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

39 * insdel.c (move_gap): Remove.
40 (move_gap_both): Add eassert.
41 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

51 switches from 'signal' to 'pthread_sigmask', which is safer in
52 multithreaded applications.
53 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
54 which has already arranged for that.
55 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
56 This is the main part of the bug fix.

77 Use Qstringp for default-directory, buffer-file-name,
78 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
79 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for

99 * coding.c (coding_alloc_by_making_gap): Use it.
100 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
101 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
103 2013-01-08 Juri Linkov <juri@jurta.org>
105 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
106 of (supports :underline (:style wave)). (Bug#13000)

124 trailing dash is properly added.
126 2013-01-05 Eli Zaretskii <eliz@gnu.org>
128 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
129 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
130 digits for buffer positions, before misalignment starts.
131 Display "0" for integer "object" field.
132 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
133 Display the newline glyph more unambiguously.
135 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
137 * nsterm.m (ns_draw_underwave):
138 * w32term.c (w32_draw_underwave):
139 * xterm.c (x_draw_underwave): Make underwave look more triangular
140 and also degrade gracefully for small fonts. (Bug#13000)
142 * nsterm.m (ns_draw_text_decoration):
143 * w32term.c (x_draw_glyph_string):
144 * xterm.c (x_draw_glyph_string): Don't use previous underline
145 thickness and position if previous underline type is underwave.
147 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
149 * fileio.c (Ffile_acl): Undocument return format.

153 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
155 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
158 * dired.c (file_name_completion):
159 * doc.c (get_doc_string):

164 * minibuf.c (Ftry_completion):
165 * term.c (tty_ins_del_lines):
166 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
167 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
169 2012-12-31 Eli Zaretskii <eliz@gnu.org>
171 * w32.c (unsetenv): Set up the string passed to _putenv
173 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
174 for the bug this caused.
176 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
178 * coding.c (Qmac): Now static.
180 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
182 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
183 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
184 handlebox_widget. Set toolbar_in_hbox to false/true, set
185 toolbar_is_packed to true.
186 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
187 (update_frame_tool_bar): Check toolbar_is_packed for packing.

191 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
192 Check toolbar_is_packed.
193 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
194 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
195 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
197 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
198 (xg_update_menubar): Update title only if
199 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
200 (xg_update_submenu): Skip tearoff only if
201 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
202 (xg_initialize): Initialize xg_detached_menus only if
203 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
205 * xterm.h (struct x_output): Surround handlebox_widget with
206 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
207 toolbar_in_hbox is bool.
209 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
211 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
212 (LIBS_GNUSTEP): Define.
213 (LIBES): Add $(LIBS_GNUSTEP).

216 2012-12-30 Eli Zaretskii <eliz@gnu.org>
218 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
219 continuation glyph on a TTY with an indication of an empty line.
222 2012-12-29 Eli Zaretskii <eliz@gnu.org>
224 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
225 file's SELinux context or ACLs successfully set, nil otherwise.
227 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
229 * w32proc.c (reader_thread): Avoid passing NULL handles to
230 SetEvent and WaitForSingleObject.
232 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
234 Port EXTERNALLY_VISIBLE to Clang 3.2.
235 * conf_post.h (__has_attribute): New macro.
236 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
238 2012-12-27 Glenn Morris <rgm@gnu.org>
240 * cygw32.c (Fcygwin_convert_file_name_to_windows)

243 2012-12-27 Eli Zaretskii <eliz@gnu.org>
245 * fileio.c (file_name_as_directory, directory_file_name):
246 Accept an additional argument MULTIBYTE to indicate whether the input C
247 came from a multibyte or a unibyte Lisp string; all callers
248 adjusted. Don't assume the input string is always multibyte.
250 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
251 don't ENCODE_FILE them, and return a unibyte string if the input
253 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
254 don't assume the input strings will always be multibyte. If the
255 input strings are multibyte, decode strings obtained from C

260 * lisp.h (toplevel): Add two notices to the comment about
261 defining a new Lisp data type.
262 * print.c (print_object): If Lisp_Save_Value object's pointer
263 is the address of a memory area containing Lisp_Objects, try
265 * alloc.c (valid_lisp_object_p): Adjust comment.
267 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
269 * keyboard.c (record_asynch_buffer_change): Initialize an event
270 only if it's really needed.
271 * frame.h (enum output_method): Remove output_mac member since
272 it's a leftover from the deleted code.
273 * frame.c (Fframep): Adjust user here ...
274 * terminal.c (Fterminal_live_p): ... and here.
275 * coding.c (Qmac): Now here because it's only used to denote
276 end-of-line encoding type.
277 (syms_of_coding): DEFSYM it.
278 * frame.h (Qmac): Remove duplicated declaration.
280 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
282 * window.c (select_window_1): Now static, since it's used only here.
284 2012-12-25 Eli Zaretskii <eliz@gnu.org>
286 * window.c (window_body_cols): Subtract display margins from the
287 window body width on TTYs as well. See
288 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
289 for the original report.
291 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
293 * xdisp.c (redisplay_window): Remove inner local variable
294 because the outer shadowed one has the same meaning.
295 * xterm.h (struct x_output): Remove toolbar_detached member since it's
297 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
298 (xg_create_tool_bar): Adjust users.
300 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
302 * buffer.h (BUF_COMPACT): New macro to follow the common style.
303 * buffer.c (Fget_buffer_create): Use it to set compact field of
304 struct buffer_text to avoid accessing an uninitialized value
305 when compact_buffer is called for the first time.
306 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
307 (Fset_buffer_modified_p): Use buffer_window_count to check
308 whether the buffer is displayed in some window.
309 * xdisp.c (message_dolog): Likewise.
311 2012-12-23 Eli Zaretskii <eliz@gnu.org>
313 * w32.c (acl_set_file): If setting the file security descriptor
314 fails, and the new DACL is identical to the existing one, silently
315 return success. This fixes problems for users backing up their
316 own files without having the necessary privileges for setting
317 security descriptors.
319 * w32proc.c (reader_thread): Do not index fd_info[] with negative
321 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
322 after WaitForSingleObject returns normally. This expedites reader
323 thread shutdown when delete_child triggers it.
324 (reap_subprocess): More accurate commentary for why we call
325 delete_child only when cp->fd is negative.
327 * w32.c (sys_close): Do not call delete_child on a subprocess
328 whose handle is not yet closed. Instead, set its file descriptor
329 to a negative value, so that reap_subprocess will call
330 delete_child on that subprocess when its SIGCHLD arrives.
331 This avoids closing handles used for communications between sys_select
332 and reader_thread, which doesn't give sys_select a chance to
333 notice that the process exited and invoke the SIGCHLD handler for
336 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
338 * nsfns.m (Fns_do_applescript): Run event loop until script has
339 been executed (Bug#12969).
340 (ns_run_ascript): Chech as_script for nil, set to nil after
343 2012-12-22 Martin Rudalics <rudalics@gmx.at>
345 * window.c (Fselect_window): Reword doc-string (Bug#13248).

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

409 (redisplay_internal): Don't bother selecting the frame to get the
410 proper value of frame-local variables (bug#13225).
412 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
414 * textprop.c (set_text_properties_1): Do not allow NULL interval.
415 Rename 4th argument since it may be buffer or string. Adjust comment.
416 * intervals.c (graft_intervals_info_buffer): Find an interval here.
418 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
420 * coding.c (Fdetect_coding_region): Do not check start and end with
421 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
422 (code_convert_region): Likewise.
424 2012-12-18 Eli Zaretskii <eliz@gnu.org>
426 * w32.c (acl_get_file, acl_set_file): Run the file name through
427 map_w32_filename, and resolve any symlinks in the file name, like
429 (acl_set_file): Call revert_to_self, if any privileges were
432 2012-12-17 Juanma Barranquero <lekktu@gmail.com>

435 ($(BLD)/w32.$(O)): Update dependencies.
437 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
439 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
440 propagate redisplay's scrolling (if any) to the right window.
441 (redisplay_internal): Use ensure_selected_frame.
442 (display_mode_lines): Complete last fix.
443 * window.c (select_window_1): New func, extracted from select_window.
444 (select_window): Use it.
445 * window.h (select_window_1): Declare.

471 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
473 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
474 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
475 for some of that bug's symptoms can now cause Emacs to abort.
476 Remove the workaround.
477 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
478 The bug that caused SIGCHLD to get lost has been fixed, and the
479 workaround for it can now cause Emacs to abort.
481 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
483 * sysdep.c (emacs_abort): Bump backtrace size to 40.
484 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
485 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

507 (record_infile, record_pending_deletion): New prototypes.
509 * w32proc.c (new_child): Initialize input_file and
510 pending_deletion members of the child.
511 (delete_child): Delete the child's temporary input file, if any,
512 that is pending deletion.

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

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

554 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
555 try to get accurate owner and group information from NT file
556 security APIs. This is to make most callers of 'stat' and
557 'lstat', which don't need that information, much faster.
559 * dired.c (Ffile_attributes) [WINDOWSNT]:
560 Set w32_stat_get_owner_group to a non-zero value, to request accurate
561 owner and group information from 'lstat'.
563 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
565 * fileio.c (Finsert_file_contents): Don't put tail into head area,
566 as that confuses set-auto-coding, so insist on the head-read
567 returning the full 1024 bytes. Let lseek compute the tail offset;
568 less work for us. Do not ignore I/O errors when reading the tail.

595 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
597 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
598 fstat shouldn't fail, and if it does fail copy-file should not proceed.
599 Remove unnecessary S_ISLNK test, as (contra the comments) this
600 function can't copy symlinks. Improve quality of error message
601 when attempting to copy files that are neither regular files nor

612 2012-12-12 Daniel Colascione <dancol@dancol.org>
614 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
615 the dumped Emacs is not a sparse file, greatly improving Cygwin
616 "make bootstrap" performance.

625 * xdisp.c (handle_face_prop): Fix logic of computing
626 it->start_of_box_run_p.
627 (append_space_for_newline): If the glyph row is R2L, reset the
628 iterator's end_of_box_run_p flag before prepending the space glyph.
629 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
630 iterator's start_of_box_run_p flag before prepending the stretch.
631 (append_glyph, produce_image_glyph, append_composite_glyph)
632 (append_stretch_glyph, append_glyphless_glyph): Reverse the
633 left_box_line_p and right_box_line_p flags of the glyph for R2L
634 glyph rows. (Bug#13011)

646 2012-12-11 Eli Zaretskii <eliz@gnu.org>
648 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
649 encoded_file_name, which is what it is.
651 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

684 (hinst): Remove unneeded extern declaration.
685 (_start): Remove initialization of above variables; remove
686 initialization of hinst, as cache_system_info now does that.
688 * emacs.c (main): Call cache_system_info early in startup; we
689 previously weren't calling it in Cygwin builds.

957 fails, signal an error instead of continuing with an empty
959 Encode expanded temp file pattern before passing it to mkstemp or
962 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
963 Encode the file name before passing it to dostounix_filename, in
964 case it will downcase it (under w32-downcase-file-names).

969 Minor call-process cleanups.
970 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS

995 Don't let call-process be a zombie factory (Bug#12980).
996 Fixing this bug required some cleanup of the signal-handling code.
997 As a side effect, this change also fixes a longstanding rare race
998 condition whereby Emacs could mistakenly kill unrelated processes,
999 and it fixes a bug where a second C-g does not kill a recalcitrant
1000 synchronous process in GNU/Linux and similar platforms.
1001 The patch should also fix the last vestiges of Bug#9488,
1002 a bug which has mostly been fixed on the trunk by other changes.
1003 * callproc.c, process.h (synch_process_alive, synch_process_death)
1004 (synch_process_termsig, sync_process_retcode):
1005 Remove. All uses removed, to simplify analysis and so that
1006 less consing is done inside critical sections.
1007 * callproc.c (call_process_exited): Remove. All uses replaced
1008 with !synch_process_pid.
1009 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1010 These take the role of what used to be in unwind-protect arg.
1012 (block_child_signal, unblock_child_signal):
1013 New functions, to avoid races that could kill innocent-victim processes.
1014 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1015 (call_process_kill): Record killed processes as deleted, so that
1016 zombies do not clutter up the system. Do this inside a critical
1017 section, to avoid a race that would allow the clutter.
1018 (call_process_cleanup): Fix code so that the second C-g works again
1019 on common platforms such as GNU/Linux.
1020 (Fcall_process): Create the child process in a critical section,
1021 to fix a race condition. If creating an asynchronous process,
1022 record it as deleted so that zombies do not clutter up the system.
1023 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1024 light of these changes. Omit unnecessary call to emacs_close
1025 before failure, as the unwind-protect code does that.
1026 * callproc.c (call_process_cleanup):
1027 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1028 * process.c (record_deleted_pid): New function, containing
1029 code refactored out of Fdelete_process.
1030 (Fdelete_process): Use it.
1031 (process_status_retrieved): Remove. All callers changed to use
1032 child_status_change.
1033 (record_child_status_change): Remove, folding its contents into ...
1034 (handle_child_signal): ... this signal handler. Now, this
1035 function is purely a handler for SIGCHLD, and is not called after
1036 a synchronous waitpid returns; the synchronous code is moved to
1037 wait_for_termination. There is no need to worry about reaping
1038 more than one child now.
1039 * sysdep.c (get_child_status, child_status_changed): New functions.
1040 (wait_for_termination): Now takes int * status and bool
1041 interruptible arguments, too. Do not record child status change;
1042 that's now the caller's responsibility. All callers changed.
1043 Reimplement in terms of get_child_status.
1044 (wait_for_termination_1, interruptible_wait_for_termination):
1045 Remove. All callers changed to use wait_for_termination.
1046 * syswait.h: Include <stdbool.h>, for bool.
1047 (record_child_status_change, interruptible_wait_for_termination):
1049 (record_deleted_pid, child_status_changed): New decls.
1050 (wait_for_termination): Adjust to API changes noted above.
1052 * bytecode.c, lisp.h (Qbytecode): Remove.
1053 No longer needed after 2012-11-20 interactive-p changes.
1055 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1057 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1058 the scroll margin, move point outside the margin. (Bug#13055)
1060 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1062 * gtkutil.c (my_log_handler): New function.
1063 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1065 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1067 * lisp.h (modify_region): Rename to...
1068 (modify_region_1): ...new prototype.
1069 * textprop.c (modify_region): Now static. Adjust users.
1070 * insdel.c (modify_region): Rename to...
1071 (modify_region_1): ...new function to work with current buffer.
1072 Adjust comment and users. Use true and false for booleans.
1074 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1076 * alloc.c (free_save_value): New function.
1077 (safe_alloca_unwind): Use it.
1078 * lisp.h (free_save_value): New prototype.
1079 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1081 (save_excursion_restore): Adjust to match saved data structure.
1082 Use free_save_value to offload some work from GC. Drop obsolete
1085 2012-12-03 Chong Yidong <cyd@gnu.org>
1087 * fileio.c (Vauto_save_list_file_name): Doc fix.
1089 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1091 * w32fns.c: Remove prototype of atof.
1092 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1094 (file_dialog_callback): Make it UINT_PTR.
1096 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1099 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1100 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1103 2012-12-03 Glenn Morris <rgm@gnu.org>
1105 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1107 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1109 Fix xpalloc confusion after memory is exhausted.
1110 * alloc.c (xpalloc): Comment fix.
1111 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1112 and signals an error, do not clear charset_table_size, as
1113 charset_table is still valid.
1114 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1116 Use execve to avoid need to munge environ (Bug#13054).
1117 * callproc.c (Fcall_process):
1118 * process.c (create_process):
1119 Don't save and restore environ; no longer needed.
1120 * callproc.c (child_setup):
1121 Use execve, not execvp, to preserve environ.
1123 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1125 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1127 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1129 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1130 display for sliced images (Bug#10500).
1132 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1134 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1136 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1137 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1139 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1141 * xdisp.c (window_outdated): Remove eassert since it hits
1142 some suspicious corner cases (see Bug#13007 and Bug#13012).
1143 (mode_line_update_needed): New function.
1144 (redisplay_internal, redisplay_window): Use it.
1145 (ensure_selected_frame): New function.
1146 (redisplay_internal, unwind_redisplay): Use it.
1147 (redisplay_internal): Move comment about buffer_shared...
1148 (buffer_shared_and_changed): ...near to its real use.
1150 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1152 * callproc.c (Fcall_process): Don't misreport vfork failure.
1154 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1156 * callproc.c (Fcall_process): Fix vfork portability problems.
1157 Do not assume that fd[0], count, filefd, and save_environ survive
1158 vfork. Fix bug whereby wrong errno value could be reported for
1159 pipe failure. Some minor cleanups, too, as follows. Move buf and
1160 bufsize to the context where they're needed. Change new_argv to
1161 be of type char **, as this is more convenient and avoids casts.
1162 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1163 Now local constants, not macros.
1165 2012-11-18 Kenichi Handa <handa@gnu.org>
1167 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1168 for the variable "f".
1170 2012-11-13 Kenichi Handa <handa@gnu.org>
1172 * font.c (font_unparse_xlfd): Exclude special characters from the
1173 generating XLFD name.
1175 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

1200 violations when repeatedly clicking on the "Top" link of the
1201 "bread-crumbs" in Info buffers.

1215 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1216 between bpos_covered and bpos_max. This fixes cursor display when
1217 several display strings follow each other.
1219 * .gdbinit (pgx): If the glyph's object is a string, display the
1220 pointer to string data, rather than the value of the string object
1221 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1223 * indent.c (Fvertical_motion): If the starting position is covered
1224 by a display string, return to one position before that, to avoid
1225 overshooting it inside move_it_to. (Bug#12930)
1227 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1229 * frame.h (struct frame): Remove display_preempted member

1238 Drop unused pending_menu_activation member.
1239 * xterm.h (struct x_output): Drop outdated #if 0 code.
1240 Use bitfields for explicit_parent, asked_for_visible,
1241 has_been_visible and net_wm_state_hidden_seen members.

1245 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1246 of a literal "/". (Bug#12955)
1247 (gl-stamp): Invoke fc.exe directly, not through cmd.

1251 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1252 * dired.c: Assume HAVE_DIRENT_H.
1253 (NAMLEN): Remove, replacing with ...
1254 (dirent_namelen): New function. All uses changed. Use the GNU macro
1255 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1256 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1257 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1258 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1260 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1261 * ndir.h: Rename to ../nt/inc/dirent.h.
1262 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1263 Do not include <dirent.h>; no longer needed.
1264 * w32.c: Include <dirent.h> rather than "ndir.h".
1266 2012-11-23 Chong Yidong <cyd@gnu.org>
1268 * xftfont.c (xftfont_open): Remove duplicate assignment.
1270 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1272 * alloc.c (Fgarbage_collect): Unblock input after clearing
1273 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1274 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1275 * msdos.c (IT_frame_up_to_date): Use it here...
1276 * w32term.c (w32_frame_up_to_date): ...here...
1277 * xterm.c (XTframe_up_to_date): ...and here...
1278 * nsterm.m (ns_frame_up_to_date): ...but not here.
1279 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1281 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1282 Do not check whether GC is in progress.

1290 'tail' and 'frame' local variables.
1292 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1294 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1295 with Windows system header.
1297 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1299 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1300 * alloc.c: Assume unistd.h exists.

1304 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1305 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1306 * w32.h (getcwd): Remove decl.
1308 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>

1316 * emacs.c (main): Set the G_SLICE environment variable for all
1317 Cygwin builds, not just GTK builds. See
1318 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1320 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1322 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1323 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1324 Define for the MSVC compiler.
1326 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1328 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1329 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1330 dostounix_filename. Prevents crashes down the road, because
1331 dostounix_filename assumes it gets a unibyte string.
1332 Reported by Michel de Ruiter <michel@sentient.nl>, see
1333 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

1371 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1372 cygwin_convert_file_name*.
1374 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1375 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1377 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1379 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1381 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1383 * w32select.c: Include w32common.h before w32term.h, so that
1384 windows.h gets included before w32term.h uses some of its
1385 features, see below.
1387 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1389 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

1395 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1396 (ns_select): Return at once if events are held (Bug#12834).
1398 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1400 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1401 Needed following 2012-10-20 change. (Bug#12902)
1403 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1405 * w32proc.c (waitpid): Remove unused label get_result.
1407 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1409 * makefile.w32-in (SYSWAIT_H): New macro.
1410 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1411 ($(BLD)/sysdep.$(O)): Update dependencies.
1413 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>

1417 * emacs.c, term.c (O_RDWR): Remove.
1418 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1419 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1420 * nsterm.m: Assume <fcntl.h> exists.
1421 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1422 (create_pty, Fmake_network_process, server_accept_connection)
1423 (wait_reading_process_output, init_process_emacs):
1425 (wait_reading_process_output): Put in a special case for WINDOWSNT
1426 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1427 It's not clear this is needed, but it's a more-conservative change.
1428 (create_process): Assume FD_CLOEXEC.
1429 (create_process, create_pty): Assume O_NOCTTY.
1430 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1431 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1432 Omit if not DOS_NT, since F_GETFL is not defined there.
1433 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1434 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1436 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1437 lack it, since gnulib guarantees this.
1438 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1440 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1442 * w32.c (faccessat): Pretend that directories have the execute bit
1443 set. Emacs expects that, e.g., in files.el:cd-absolute.
1445 * w32proc.c (create_child): Don't clip the PID of the child
1446 process to fit into an Emacs integer, as this is no longer a
1448 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1449 reaping only the process specified by PID argument, if that is
1450 positive. Use PID instead of dead_child to know which process to
1451 reap. Wait for the child to die only if WNOHANG is not in
1453 (sys_select): Don't set dead_child.
1455 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1456 as it is no longer needed.
1458 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1460 (record_child_status_change): Remove the setting of
1461 record_at_most_one_child for the !WNOHANG case.
1463 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1465 Fix problems in ns port found by static checking.
1466 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1467 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1468 not to process group.
1469 (ns_select): Use emacs_write, not write, as that's more robust
1470 in the presence of signals.
1471 (fd_handler:): Check for read errors.
1473 2012-11-16 Glenn Morris <rgm@gnu.org>
1475 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1477 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1479 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1481 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1483 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1484 use the same value of thread handle.
1485 (start_timer_thread): If the timer thread exited (due to error),
1486 clean up by closing the two handles it used. Duplicate the caller
1487 thread's handle here, so it gets duplicated only once, when
1488 launching the timer thread. Set priority of the timer thread, not
1490 (getitimer): Don't duplicate the caller thread's handle here.
1493 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1495 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1498 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1500 Remove no-longer-used pty_max_bytes variable.
1501 * process.c (pty_max_bytes): Remove; unused.
1502 (send_process): Do not set it.
1504 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1506 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1507 Update dependencies.
1509 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1511 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1512 This follows up on the 2012-09-29 patch that removed indirection
1513 for the 'function' field. Reported by Sergey Vinokurov in
1514 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1516 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1518 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1519 different name, as the MS runtime does not have such a function,
1520 and probably never will.) All callers changed. Ignore DIRFD
1521 value if PATH is an absolute file name, to match Posix spec
1522 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1525 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1527 * xdisp.c (echo_area_display, redisplay_internal):
1528 Omit redundant check whether frame_garbaged is set.
1530 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1532 Use faccessat, not access, when checking file permissions (Bug#12632).
1533 This fixes a bug that has been present in Emacs since its creation.
1534 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1535 which must set some sort of record. (Torek's bug report was against
1536 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1537 same common flaw.) See Torek's Usenet posting
1538 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1539 Posted: Fri Apr 8 14:18:56 1983.
1540 * Makefile.in (LIB_EACCESS): New macro.
1542 * callproc.c (init_callproc):
1543 * charset.c (init_charset):
1544 * fileio.c (check_existing, check_executable, check_writable)
1546 * lread.c (openp, load_path_check):
1547 * process.c (allocate_pty):
1549 Use effective UID when checking permissions, not real UID.
1550 * callproc.c (init_callproc):
1551 * charset.c (init_charset):
1552 * lread.c (load_path_check, init_lread):
1553 Test whether directories are accessible, not merely whether they exist.
1554 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1555 * fileio.c (check_existing, check_executable, check_writable)
1557 Use symbolic names instead of integers for the flags, as they're
1559 (check_writable): New arg AMODE. All uses changed.
1560 Set errno on failure.
1561 (Ffile_readable_p): Use faccessat, not stat + open + close.
1562 (Ffile_writable_p): No need to call check_existing + check_writable.
1563 Just call check_writable and then look at errno. This saves a syscall.
1564 dir should never be nil; replace an unnecessary runtime check
1565 with an eassert. When checking the parent directory of a nonexistent
1566 file, check that the directory is searchable as well as writable, as
1567 we can't create files in unsearchable directories.
1568 (file_directory_p): New function, which uses 'stat' on most platforms
1569 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1570 (Ffile_directory_p, Fset_file_times): Use it.
1571 (file_accessible_directory_p): New function, which uses a single
1572 syscall for efficiency.
1573 (Ffile_accessible_directory_p): Use it.
1574 * xrdb.c (file_p): Use file_directory_p.
1575 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1576 * lread.c (openp): When opening a file, use fstat rather than
1577 stat, as that avoids a permissions race. When not opening a file,
1578 use file_directory_p rather than stat.
1579 (dir_warning): First arg is now a usage string, not a format.
1580 Use errno. All uses changed.
1581 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1582 that merely introduced a race.
1583 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1584 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1585 and similarly for the other O_* flags.
1586 * w32.c (sys_faccessat): Rename from sys_access and switch to
1587 faccessat's API. All uses changed.
1588 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1589 (magic_db): Rename from magic_file_p.
1590 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1591 char *, so that we don't have to test for file existence
1592 separately from opening the file for reading. This removes a race
1593 fixes a permission-checking problem, and simplifies the code.
1595 (file_p): Remove; no longer needed.
1597 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1599 Omit glyphs initialization at startup.
1600 * dispnew.c (glyphs_initialized_initially_p): Remove.
1601 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1602 (Fredraw_frame): Move actual code from here...
1603 (redraw_frame): ...to here. Add eassert. Adjust comment.
1604 (Fredraw_display): Use redraw_frame.
1605 * xdisp.c (clear_garbaged_frames): Likewise.
1607 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1609 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1610 passed to pint2str and pint2hrstr to be at most the size of the
1611 frame's decode_mode_spec_buffer. This avoids crashes with very
1612 large values of FIELD_WIDTH argument to decode_mode_spec.
1615 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1617 Fix a race with verify-visited-file-modtime (Bug#12863).
1618 Since at least 1991 Emacs has ignored an mtime difference of no
1619 more than one second, but my guess is that this was to work around
1620 file system bugs that were fixed long ago. Since the race is
1621 causing problems now, let's remove that code.
1622 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1623 whose time stamp is off by no more than a second. Insist that the
1624 file time stamps match exactly.
1626 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1628 * frame.h (struct frame): Convert external_tool_bar member to
1629 1-bit unsigned bitfield.
1630 * termhooks.h (struct terminal): Remove mouse_moved member since
1631 all users are long dead. Adjust comment on mouse_position_hook.
1633 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1635 Simplify by using FOR_EACH_FRAME here and there.
1636 * frame.c (next_frame, prev_frame, other_visible_frames)
1637 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1638 * w32term.c (x_window_to_scroll_bar): Likewise.
1639 * window.c (window_list): Likewise.
1640 * xdisp.c (x_consider_frame_title): Likewise.
1641 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1642 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1643 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1644 * xmenu.c (menubar_id_to_frame): Likewise.
1645 * xselect.c (frame_for_x_selection): Likewise.
1646 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1647 (x_window_to_menu_bar): Likewise.
1648 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1650 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1652 * data.c (Qdefalias_fset_function): Now static.
1654 Another tweak to vectorlike_header change.
1655 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1656 Remove, and replace all uses with ...
1657 (next_in_free_list, set_next_in_free_list):
1658 New functions, which respect C's aliasing rules better.
1660 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1662 * window.c (list4i): Rename from 'quad'. All uses changed.
1663 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1665 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1667 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1668 warning about mixing declarations and code in ISO C90.
1670 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1672 * window.c (Fsplit_window_internal): Set combination limit of
1673 new parent window to t iff Vwindow_combination_limit is t;
1674 fixing a regression introduced with the change from 2012-09-22.
1675 (Fset_window_combination_limit): Fix doc-string.
1677 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1679 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1680 amount when the scroll margins are too large. When scrolling
1681 backwards in the buffer, give up if cannot reach point or the
1682 scroll margin within a reasonable number of screen lines.
1683 Fixes point position in window under scroll-up/down-aggressively when
1684 point is positioned many lines beyond the window top/bottom.
1687 * ralloc.c (relinquish): If real_morecore fails to return memory
1688 to the system, don't crash; instead, leave the last heap
1689 unchanged and return. (Bug#12774)
1691 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1693 * lisp.h (AUTOLOADP): New macro.
1694 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1695 * data.c (Ffset): Remove special ad-advice-info handling.
1696 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1698 (Finteractive_form): Simplify.
1699 (Fquo): Don't insist on having at least 2 arguments.
1700 (Qdefalias_fset_function): New var.
1702 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1704 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1706 * nsfont.m (Qcondensed, Qexpanded): New variables.
1707 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1708 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1710 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1712 Fix recently introduced crash on MS-Windows (Bug#12839).
1713 * w32term.h (struct scroll_bar): Use convenient header.
1714 (SCROLL_BAR_VEC_SIZE): Remove.
1715 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1717 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1719 Tweak last vectorlike_header change.
1720 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1721 vectorlike object on the free list. This is introduced to avoid
1722 some (but not all) pointer casting and aliasing problems, see
1723 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1724 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1726 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1728 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1730 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1731 been removed, so remove them here also.
1733 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1735 * doc.c (Fdocumentation): Handle new property
1736 dynamic-docstring-function to replace the old ad-advice-info.
1738 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1740 * fns.c (Qeql, hashtest_eq): Now static.
1742 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1744 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1745 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1746 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
1747 * buffer.c (compare_overlays): Use XLI rather than XHASH.
1749 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1751 Use same hash function for hashfn_profiler as for hash_string etc.
1752 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1753 * lisp.h (sxhash_combine): New inline function, with the contents
1754 of the old SXHASH_COMBINE.
1755 * profiler.c (hashfn_profiler): Use it, instead of having a
1756 special hash function containing a comparison that always yields 1.
1758 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1760 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1761 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1762 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1765 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1767 * image.c (xpm_make_color_table_h): Fix compiler error because
1768 make_hash_table changed.
1770 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1772 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1774 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1776 Use ad-hoc comparison function for the profiler's hash-tables.
1777 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1778 (make_log): Use them.
1779 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1780 call Fequal any more.
1781 (Ffunction_equal): New function.
1782 (cmpfn_profiler, hashfn_profiler): New functions.
1783 (syms_of_profiler): Initialize them.
1784 * lisp.h (struct hash_table_test): New struct.

1789 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1790 (hash_lookup, hash_remove_from_table): Move assertion checking of
1791 hashfn result here. Check hash-equality before calling cmpfn.
1792 (Fmake_hash_table): Adjust call to make_hash_table.
1793 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
1794 (syms_of_fns): Initialize them.

1798 * print.c (print_object): Adjust to new hash-table struct.
1799 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
1801 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1803 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1804 value of w32-scroll-lock-modifier is neither nil nor one of the
1805 known key modifiers. (Bug#12806)
1807 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1809 Shrink struct vectorlike_header to the only size field.
1810 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1812 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1813 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1814 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1815 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1816 information from the vector header. Adjust comment.
1817 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
1818 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
1820 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
1821 (struct vectorlike_header): Remove next member. Adjust comment.

1824 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
1825 (sweep_string, lisp_malloc): Remove useless prototypes.
1826 (enum mem_type): Adjust comment.
1827 (NEXT_IN_FREE_LIST): New macro.
1828 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1829 (Fmake_bool_vector): Likewise.
1830 (struct large_vector): New type to represent allocation unit for
1831 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1832 (large_vectors): Change type to struct large_vector.
1833 (allocate_vector_from_block): Simplify.
1834 (PSEUDOVECTOR_NBYTES): Replace with...
1835 (vector_nbytes): ...new function. Adjust users.
1836 (sweep_vectors): Adjust processing of large vectors.
1837 (allocate_vectorlike): Likewise.
1838 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1839 Add easserts. Adjust XSETPVECTYPESIZE usage.
1840 (allocate_buffer): Use BUFFER_PVEC_INIT.
1841 (live_vector_p): Adjust to match large vector.
1842 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1843 * buffer.h (struct buffer): Add next member.
1844 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1846 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1847 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1848 (copy_hash_table): Adjust to match vector header change.
1849 * lread.c (defsubr): Use XSETPVECTYPE.
1850 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
1851 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
1852 (xvecsize): New command.
1854 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1856 * keyboard.c (event_to_kboard): Do not dereference
1857 frame_or_window field of SELECTION_REQUEST_EVENT
1858 and SELECTION_CLEAR_EVENT events (Bug#12814).
1859 * xterm.h (struct selection_input_event): Adjust comment.
1861 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1863 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1864 such as Scroll Lock, if the respective keys are treated as
1865 function keys, not as modifiers. This avoids destroying non-ASCII
1866 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1868 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1870 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1872 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1874 Restore some duplicate definitions (Bug#12814).
1875 This undoes part of the 2012-11-03 changes. Some people build
1876 with plain -g rather than with -g3, and they need the duplicate
1877 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1878 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1879 Define as macros, as well as as enums or as constants.
1881 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1883 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1884 to keypad keys (Bug#12816).
1886 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1888 Minor adjustments of recently-changed frame functions.
1889 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1890 known to be a frame (we're in the FRAMEP branch).
1891 * lisp.h (Qframep): Remove decl. frame.h declares this.
1892 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1893 since they're meant for Lisp fixnum values.
1895 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1897 * window.c (Fwindow_combination_limit): Revert to the only
1898 required argument and adjust docstring as suggested in
1899 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1900 by Martin Rudalics <rudalics@gmx.at>.
1902 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

1917 * lisp.h (frame_buffer_predicate): Remove prototype.
1918 * buffer.c (Fother_buffer): Use decode_any_frame.
1919 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1920 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1921 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1922 (Fclose_font, Ffont_info): Use decode_live_frame.
1923 * fontset.c (check_fontset_name): Likewise.
1924 * terminal.c (Fframe_terminal): Likewise.
1925 * w32fns.c (check_x_frame): Likewise.
1926 * window.c (Fminibuffer_window, Fwindow_at)
1927 (Fcurrent_window_configuration): Likewise.

1931 * xfaces.c (frame_or_selected_frame): Remove.
1932 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1933 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)

1946 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1947 (Fwindow_combination_limit): Allow zero number of arguments.
1949 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1951 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1953 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1954 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1955 file descriptor 2 for standard error. (Bug#12805)
1957 2012-11-05 Chong Yidong <cyd@gnu.org>
1959 * process.c (wait_reading_process_output): Revert previous change.
1961 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1963 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1964 This removes code that has been obsolete since around 1990.
1965 * callproc.c (Fcall_process):
1967 * process.c (create_process):
1968 * term.c (dissociate_if_controlling_tty):
1969 Assume setsid exists.
1970 * callproc.c (child_setup): Assume setpgid exists and behaves as
1971 per POSIX.1-1988 or later.
1972 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1973 * emacs.c (shut_down_emacs):
1974 * sysdep.c (sys_suspend, init_foreground_group):
1975 Assume getpgrp behaves as per POSIX.1-1998 or later.
1976 * msdos.c (setpgrp): Remove.
1977 (tcgetpgrp, setpgid, setsid): New functions.
1978 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1979 * term.c (no_controlling_tty): Remove; unused.
1980 * w32proc.c (setpgrp): Remove.
1981 (setsid, tcgetpgrp): New functions.
1983 Simplify by assuming __fpending.
1984 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1985 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1986 Do not assume that __fpending's result fits in int.
1988 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1990 Remove EMACS_OUTQSIZE+sleep hack.
1991 * dispnew.c (update_frame_1): Remove hack for terminals slower
1992 than 2400 bps, which throttled Emacs by having it sleep.
1993 This code hasn't worked since at least 2007, when the multi-tty stuff
1994 was added, and anyway those old terminals are long dead.
1995 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1996 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1998 Fix data-loss with --version (Bug#9574).
1999 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2000 as we can't assume that emacs_strerror is initialized, and strerror
2001 is good enough here.
2002 (main): Invoke atexit earlier, to catch earlier instances of
2003 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2005 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2007 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2008 (keyDown): Remap keypad keys to X11 virtual key codes.
2010 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2012 Fix data-loss with --batch (Bug#9574).
2013 * emacs.c: Include <close-stream.h>.
2014 (close_output_streams): New function.
2015 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2016 and handles errors appropriately.
2017 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2020 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2021 The symptom is a diagnostic "GLib-WARNING **: In call to
2022 g_spawn_sync(), exit status of a child process was requested but
2023 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2024 waitpid(), so exit status can't be returned." The diagnostic
2025 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2026 The real bug is a race condition between Emacs and glib: Emacs
2027 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2028 so that glib can't find it. Work around the bug by invoking
2029 waitpid only on subprocesses that Emacs itself creates.
2030 * process.c (create_process, record_child_status_change):
2031 Don't use special value -1 in pid field, as the caller now must
2032 know the pid rather than having the callee infer it.
2033 The inference was sometimes incorrect anyway, due to another race.
2034 (create_process): Set new 'alive' member if child is created.
2035 (process_status_retrieved): New function.
2036 (record_child_status_change): Use it.
2037 Accept negative 1st argument, which means to wait for the
2038 processes that Emacs already knows about. Move special-case code
2039 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2040 processes that have already been waited for, by testing and
2041 clearing new 'alive' member.
2042 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2043 now does this internally.
2044 (handle_child_signal): Let record_child_status_change do all
2045 the work, since we do not want to reap all exited child processes,
2046 only the child processes that Emacs itself created.
2047 * process.h (Lisp_Process): New boolean member 'alive'.
2049 Omit duplicate definitions no longer needed with gcc -g3.
2050 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2051 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2052 Define only as macros. There's no longer any need to also define
2053 these symbols as enums or as constants, since we now assume
2054 gcc -g3 when debugging.
2056 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2058 * lisp.mk: Adjust comments to the fact that term/internal is now
2059 loaded from loadup.el.
2061 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2062 (msdos_fatal_signal): New function.
2063 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2066 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2067 for GCC versions before 4.
2068 (emacs_raise): Define to call msdos_fatal_signal.
2070 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2071 iterator when starting in the middle of a display or overlay
2074 2012-11-03 Chong Yidong <cyd@gnu.org>
2076 * process.c (wait_reading_process_output): Clean up the last
2079 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2081 * process.c (wait_reading_process_output): Avoid a race condition
2082 with SIGIO delivery (Bug#11536).
2084 2012-11-03 Chong Yidong <cyd@gnu.org>
2086 * buffer.c (cursor_type): Untabify docstring.
2088 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2090 * frame.h (struct frame): Drop can_have_scroll_bars member
2091 which is meaningless for a long time. Adjust comments.
2092 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2093 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2095 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2097 * window.c (decode_next_window_args): Update window arg after
2098 calling decode_live_window and so fix crash reported at
2099 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2100 by Juanma Barranquero <lekktu@gmail.com>.
2101 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2102 * font.c (Ffont_at): Likewise.
2104 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2106 * widget.c (resize_cb): New function.
2107 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2108 (EmacsFrameResize): Check if all is up to date before changing frame
2111 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2113 Implement backtrace output for fatal errors on MS-Windows.
2114 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2115 (BACKTRACE_LIMIT_MAX): New macro.
2116 (w32_backtrace): New function.
2117 (emacs_abort): Use w32_backtrace when the user chooses not to
2118 attach a debugger. Update the text of the abort dialog.
2120 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2122 Window-related stuff cleanup here and there.
2123 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2124 Use decode_any_window.
2125 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2126 * xdisp.c (Fformat_mode_line): Likewise.
2127 * font.c (Ffont_at): Use decode_live_window.
2128 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2129 * window.c (decode_next_window_args): Likewise.
2130 (decode_any_window): Remove static.
2131 * window.h (decode_any_window): Add prototype.
2132 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2133 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2136 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2138 Remove pad from struct input_event.
2139 * termhooks.h (struct input_event): Remove padding field.
2141 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2142 member is never cons for a long time. Adjust comment.
2143 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2144 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2145 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2146 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2148 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2150 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2152 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2154 Fix crash when using Emacs as commit editor for git (Bug#12697).
2155 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2156 and it is configured in conf_post.h.
2157 (Fcall_process): Don't invoke both setsid and setpgid; the former
2158 is enough, if it exists.
2159 * callproc.c (Fcall_process, child_setup):
2160 * process.c (create_process): Use setpgid.
2161 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2163 * dispnew.c (init_display): Initialize the foreground group
2164 if we are running a tty display.
2165 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2166 * lisp.h (init_foreground_group): New decl.
2167 * sysdep.c (inherited_pgroup): New static var.
2168 (init_foreground_group, tcsetpgrp_without_stopping)
2169 (narrow_foreground_group, widen_foreground_group): New functions.
2170 (init_sys_modes): Narrow foreground group.
2171 (reset_sys_modes): Widen foreground group.
2173 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2175 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2177 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2179 * minibuf.c (read_minibuf): Restore current buffer since
2180 choose_minibuf_frame calling Fset_frame_selected_window may
2181 change it (Bug#12766).
2183 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2185 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2187 2012-10-30 Kenichi Handa <handa@gnu.org>
2189 * font.c (Ffont_at): If WINDOW is specified and it is not
2190 displaying the current buffer, signal an error.
2192 2012-10-29 Daniel Colascione <dancol@dancol.org>
2194 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2195 In preparation for fixing bug#12739, move these functions from
2198 * coding.h, coding.c: ... to here, and compile them only when
2199 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2200 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2202 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2204 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2205 (timer_loop, getitimer, setitimer): Use it instead of
2206 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2208 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2211 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2213 * nsterm.m (NO_APPDEFINED_DATA): New define.
2214 (last_appdefined_event_data): New variable
2215 (last_appdefined_event): Remove.
2216 (ns_select): Initialize t from last_appdefined_event_data instead
2217 of [last_appdefined_event data1].
2218 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2219 remove last_appdefined_event (Bug#12698).
2221 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2223 * frame.c (x_set_font): Catch internal error.
2225 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2227 Avoid overflow in w32 implementation of interval timers.
2228 When possible, for ITIMER_PROF count only times the main thread
2230 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2231 'volatile ULONGLONG' types. All the other data which was
2232 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2233 (GetThreadTimes_Proc): New typedef.
2234 (w32_get_timer_time): New function, returns a suitable time value
2236 (timer_loop): Enter critical section when accessing ULONGLONG
2237 values of the itimer_data struct, as these accesses are no longer
2238 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2239 Remove unused variable.
2240 (init_timers): Initialize s_pfn_Get_Thread_Times.
2241 (start_timer_thread): Don't assign itimer->caller_thread here.
2242 (getitimer): Assign itimer->caller_thread here.
2243 (setitimer): Always call getitimer to get the value of ticks_now.
2244 (sys_spawnve): Avoid compiler warning about format mismatch.
2246 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2248 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2249 mouse movement events if the menu bar is active. This avoids
2250 producing a busy "hour-glass" cursor by Windows if the mouse
2251 pointer is positioned over a tooltip shown for some menu item.
2253 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2255 Don't assume process IDs fit in int.
2256 * emacs.c (shut_down_emacs) [!DOS_NT]:
2257 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2258 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2259 Use pid_t, not int, to store process IDs, as 'int'
2260 is not wide enough on a few platforms (e.g., AIX and IRIX).
2262 2012-10-23 Kenichi Handa <handa@gnu.org>
2264 The following change is to make face-font-rescale-alist work
2265 correctly for non-ASCII fonts.
2267 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2268 (font_open_for_lface): Handle Vface_font_rescale_alist.
2270 2012-10-23 Chong Yidong <cyd@gnu.org>
2272 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2274 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2276 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2278 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2280 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2283 2012-10-21 Glenn Morris <rgm@gnu.org>
2285 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2287 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2289 Port to OpenBSD 5.1.
2290 * frame.c (Fmouse_position, Fmouse_pixel_position):
2291 * xdisp.c (produce_stretch_glyph):
2292 Declare local vars only when they're needed.
2293 This is clearer and avoids a warning on OpenBSD about unused vars.
2294 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2295 This is safer, and avoids OpenBSD warnings about unused vars.
2296 * keyboard.c (record_menu_key): Remove unnecessary decl.
2297 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2298 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2299 as our definition clashes with OpenBSD's.
2300 * xfaces.c (load_face_colors, check_lface_attrs)
2301 (get_lface_attributes_no_remap, get_lface_attributes)
2302 (lface_fully_specified_p, x_supports_face_attributes_p)
2303 (tty_supports_face_attributes_p, face_fontset, realize_face)
2304 (realize_x_face, realize_tty_face):
2305 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2306 merely Lisp_Object *. This is more informative and avoids
2307 a warning on OpenBSD about accessing beyond an object's size.
2309 2012-10-20 Chong Yidong <cyd@gnu.org>
2311 * lread.c (Fload): Doc fix (Bug#12592).
2313 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2315 * font.c (Ffont_at): Fix previous change.
2317 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2319 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2320 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2323 * alloc.c (NSTATICS): Decrease to 0x800.
2325 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
2327 * fns.c (Fnreverse): Include the problem element when signaling an
2330 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2332 * nsterm.m (ns_select): Check writefds before call to
2333 FD_ISSET (Bug#12668).
2335 2012-10-18 Daniel Colascione <dancol@dancol.org>
2337 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2338 (staticpro): If we run out of staticpro slots, die with an
2339 informative error instead of just calling emacs_abort.

2598 since unsigned is guaranteed to have that behavior and signed is not.
2599 (read_char): Use ptrdiff_t for string length.
2600 (get_input_pending): Remove first argument, since it was always
2601 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2602 and behave as if it had that value. Return new value of
2603 input_pending. All callers changed.
2604 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2605 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

2608 All callers changed.

2632 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
2634 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2636 * commands.h (immediate_quit): Remove duplicate decl.

2648 match what GetLastError returns. Explain why the function is
2651 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2652 'is_tooltip_frame', to avoid confusion with its global namesake.
2654 2012-10-08 Daniel Colascione <dancol@dancol.org>
2656 * xdisp.c (start_hourglass): Call w32_note_current_window when
2657 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2658 build that caused Emacs to display the hourglass cursor forever.
2660 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2661 which is broken under remote desktop, calculate the number of
2662 colors available for a display based on the display's number of
2663 planes and number of bits per pixel per plane. (bug#10397).
2665 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2667 * nsfont.m (Vfonts_in_cache): New variable.
2668 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2669 are used. Add cached fonts to Vfonts_in_cache.
2670 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2672 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2674 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now

2692 ($(BLD)/w32heap.$(O)):
2693 ($(BLD)/w32menu.$(O)):
2694 ($(BLD)/w32proc.$(O)): Add w32common.h.
2696 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now

2700 2012-10-08 Daniel Colascione <dancol@dancol.org>
2702 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2703 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2704 accidental message numbering hole. Change other messages to

2722 Remove duplicate definitions.
2724 * w32fns.c: Include w32common.h; include w32heap.h only in
2727 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2728 Use `report_file_error' instead of `error' in order to better
2729 inform users of what went wrong. Increase NTGUI_UNICODE file
2730 dialog box file name length to 32k, the maximum allowed by the NT
2733 * w32common.h: New file.
2734 (ROUND_UP, ROUND_DOWN, get_page_size)
2735 (get_allocation_unit, get_processor_type, get_w32_major_version)

2738 (OS_NT, os_subtype, cache_system_info): Move here.
2740 * unexw32.c, unexcw.c: Include w32common.h.
2742 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2743 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2744 to call syms_of_w32select.
2746 * cygw32.h: Remove obsolete EXFUN declarations.
2748 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

2760 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2762 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2765 2012-10-08 Daniel Colascione <dancol@dancol.org>
2767 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2768 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2769 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2770 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2771 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2772 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2773 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2774 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2775 now a supported configuration.
2777 * Makefile.in: consolidate image variables into LIBIMAGE; add
2778 W32_OBJ and W32_LIBS. Compile new files.
2781 (_DebPrint) declare tracing facility for W32 debugging. We need
2782 to unify tracing later.
2784 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2785 unconditional use of W32 Unicode functions. Cygwin runs only on
2786 100% Unicode operating systems.
2788 * cygw32.c: New file. Define Cygwin-specific facilities.
2789 (Fcygwin_convert_path_to_windows)
2790 (Fcygwin_convert_path_from_windows): New user functions for
2791 accessing Cygwin path-munging routines.
2793 * cygw32.h: New file.
2794 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2795 UTF-16LE strings temporarily inside non-Lisp-visible string
2798 (w32_strerror): Just what it says on the tin.
2800 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2801 also run for Cygwin; both systems have the same problem with using
2802 GUI facilities in a forked child. Also call syms_of_cygw32,
2803 syms_of_w32select in correct places.
2805 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2806 needs fork-then-exec for daemon launching.
2808 * font.h: Include frame.h.
2810 * image.c: Use the image library cache machinery only when we're
2811 compiling for native WINDOWSNT; Cygwin can use shared libraries
2812 like any other Unixlike system.
2814 * keyboard.c: Clarify a comment regarding the input loop.
2816 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2817 functions directly instead of trying to detect at runtime that our
2818 host operating system supports them. We make this change for two
2819 reasons: Cygwin lacks support for the multibyte character
2820 conversion functions used by the legacy menu code, and Cygwin
2821 never needs to rely on non-Unicode APIs.
2823 * unexw32.c (hinst): Declare extern.
2825 * w32.c: Change header order;
2826 (w32_strerror): Move to w32fns.c because we need it for
2827 non-WINDOWSNT builds.
2829 * w32.h: Add #error macro to make sure we don't include w32.h for
2830 Cygwin builds. Remove w32select declarations.
2832 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2833 w32fns.c. w32console.c is WINDOWSNT-only.
2835 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2836 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2838 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2839 (w32_major_version, w32_minor_version, w32_build_number)
2840 (os_subtype, sound_type): Define here
2841 (w32_defined_color): Make color parameter const for consistency
2842 with other _defined_color functions.
2843 (w32_createwindow): Unconditionally call w32_init_class instead of
2844 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2845 through the code is complex and unnecessary because class
2846 registration is practically free.
2847 (w32_name_of_message): New EMACSDEBUG-only function.
2848 (Fset_message_beep): Move here
2849 (Fx_open_connection): Require that the display name for Windows be
2850 "w32" for consistency, emacsclient disambiguation, and maybe, one
2851 day, multi-window-system support.
2852 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2853 Cygwin files for W32 GUI facilities, since these clearly don't
2854 expect Cygwin names.
2855 (_DebPrint): Define.
2856 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2857 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2858 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2859 (w32_last_error): Remove.
2861 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2863 * w32heap.c (syspage_mask): Declare here.
2864 (cache_system_info): Remove.
2866 * w32inevt.c (faked_key): Define globally, not statically.
2867 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2868 (w32_console_toggle_lock_key): Move to w32fns.c.
2870 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2872 * w32proc.c (_DebPrint): Move to w32fns.c.
2873 * w32select.c: Include string.h, stdio.h for Cygwin.
2874 * w32select.h: New File.
2876 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2878 (w32_message_fd): New variable. Under Cygwin, holds the file
2879 descriptor the system used to tell us about pending thread
2882 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2883 that prevented compilation under non-WINDOWSNT systems.
2885 (w32_initialize): Open /dev/windows and assign it to
2886 w32_message_fd. Provide w32 feature.
2888 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2889 (WM_EMACS_INPUT_READY): add.
2890 (prepend_msg, w32_message_fd): Declare globally.
2893 (keyboard_handle): Use only when WINDOWSNT.
2894 (notify_msg_ready): New function. Posts a message to the main
2895 thread's message queue under CYGWIN, which wakes up the main
2896 thread from select(2) by making the /dev/windows file descriptor
2897 ready. Under WINDOWSNT, it sets an event the same way the old
2900 (post, prepend_msg): Actually call notify_msg_ready instead of
2901 setting the input event directly.
2903 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2905 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2906 but it still has blocs in it, don't return it to the system,
2907 instead of aborting. (Bug#12402)
2909 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2911 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2913 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2914 MAC_OS_X_VERSION_10_6.
2915 (syms_of_nsterm): Remove comment about Panther and above for
2917 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2918 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2919 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2921 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2922 MAC_OS_X_VERSION_10_4.
2924 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2925 MAC_OS_X_VERSION_10_2.
2927 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2929 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2930 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2932 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2933 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2934 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2935 Remove ns_in_resize check.
2936 (ns_clear_frame_area): Remove resize handle code.
2938 * nsfns.m (ns_in_resize): Remove.
2939 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2940 Remove ns_in_resize check.
2942 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2944 Improve sys_siglist detection.
2945 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2946 defined as a macro, as is done in Solaris.
2947 (sys_siglist_entries): New macro.
2948 (save_strsignal): Use it.
2949 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2950 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2952 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2954 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2955 fullscreen/Fullscreen.
2957 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2958 tobar_height is new.
2960 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2961 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2962 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2963 (windowDidResize:): Check for correct window if old style fullscreen.
2964 Capitalize word in comment. Remove incorrect comment.
2965 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2966 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2967 error in drawing background.
2968 (toggleFullScreen:): Remove comment. Rearrange calls.
2969 Set toolbar values to zero, save old height in tobar_height.
2970 Restore tool bar height when leaving fullscreen.
2971 (canBecomeMainWindow): New function.
2973 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2975 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2977 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2979 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2981 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2982 that time stamps of directories could also be changed.
2983 Don't request the too broad GENERIC_WRITE, only the more restrictive
2984 FILE_WRITE_ATTRIBUTES access rights.
2986 * fileio.c (Fset_file_times): Special-case ignoring errors for
2987 directories only on MSDOS, not on MS-Windows.
2989 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2991 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2993 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2995 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2996 see whether CreateFile failed.
2998 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3000 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3001 to avoid similar races.
3002 * keyboard.c (pending_signals): Now bool, not int.
3004 Port timers to OpenBSD, plus check for timer failures.
3005 OpenBSD problem reported by Han Boetes.
3006 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3008 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3009 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3010 like OpenBSD, which has timer_settime but does not declare it.
3011 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3012 whether to use itimerspec-related primitives. All uses of
3013 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3015 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3017 * profiler.c (handle_profiler_signal): Fix a malloc race
3018 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3020 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3022 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3024 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3026 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3027 consistent with the change in return value of 'safe_strsignal'.
3029 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3031 Prefer plain 'static' to 'static inline' (Bug#12541).
3032 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3033 (bidi_set_sor_type, bidi_push_embedding_level)
3034 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3035 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

3039 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3040 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3041 Now 'static', not 'static inline'.
3043 Count overruns when profiling; change units to ns.
3044 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3045 Give extra weight to samples after overruns, to attempt to count
3046 the time more accurately.
3047 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3048 the underlying primitives nominally do ns.
3049 (Fprofiler_cpu_start): Document the change. Mention that
3050 the sampling intervals are only approximate.
3052 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3054 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3056 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3057 case for the special 0 coding-system.
3059 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3060 (Fmake_overlay): Remove redundant tests.
3061 (fix_start_end_in_overlays): Remove redundant recentering.
3063 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3065 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3066 Update dependencies.
3068 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3070 Fix a malloc race condition involving strsignal.
3071 A signal can arrive in the middle of a malloc, and Emacs's signal
3072 handler can invoke strsignal, which can invoke malloc, which is
3073 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3074 Fix it by altering the signal handler so that it does not invoke
3076 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3077 * process.c (status_message): Use const pointer, in case strsignal
3078 is #defined to safe_strsignal.
3079 * sysdep.c (sys_siglist, init_signals): Always define and
3080 initialize a substitute sys_siglist if the system does not define
3081 one, even if HAVE_STRSIGNAL.
3082 (safe_strsignal): Rename from strsignal. Always define,
3083 using sys_siglist. Return a const pointer.
3084 * syssignal.h (safe_strsignal): New decl.
3085 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3087 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3089 * w32proc.c (timer_loop): Fix code that waits for timer
3090 expiration, to avoid high CPU usage.
3092 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3094 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3095 (sweep_weak_table): Remove redundant prototypes.
3097 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3099 * emacs.c: Move the inclusion of TERM_HEADER after including
3100 windows.h on WINDOWSNT. This avoids compilation problems with
3103 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3105 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3106 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3107 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3108 as the previous version used 'void *'.
3110 * ralloc.c (ROUNDUP): Fix last change.
3111 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3114 * w32proc.c <disable_itimers>: New static flag.
3115 (init_timers): Initialize it to zero, after creating the critical
3116 sections used by the timer threads.
3117 (term_timers): Set to 1 before deleting the critical sections.
3118 (getitimer, setitimer): If disable_itimers is non-zero, return an
3119 error indication without doing anything. Reported by Fabrice
3120 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3121 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3123 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3126 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3127 term_ntproc after all the other bookkeeping, to get timers working
3128 as long as possible.
3130 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3132 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3133 Suggested by Juri Linkov in
3134 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3136 Prefer plain 'static' to 'static inline' (Bug#12541).
3137 With static functions, modern compilers inline pretty well by
3138 themselves; advice from programmers often hurts as much as it helps.
3139 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3140 this change shrinks the text size of the Emacs executable by 1.1%
3141 without affecting CPU significantly in my benchmark.
3142 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
3143 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

3217 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
3218 Now 'static', not 'static inline'.
3221 (bidi_copy_it): Do the whole copy with a single memcpy.
3222 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3224 Revert the FOLLOW-SYMLINKS change for file-attributes.
3225 Doing it right would require several changes to Tramp, and there's
3226 not enough time to get that tested before the freeze today.
3227 * dired.c (directory_files_internal, Ffile_attributes):
3230 * frame.c (x_report_frame_params): Port better to wider ints.
3231 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3232 or that pointers can be printed in 15 decimal digits.
3233 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3250 compatibility with x64.
3252 * w32heap.h: Adjust prototypes and declarations.
3254 * w32heap.c (RVA_TO_PTR, allocate_heap, sbrk, init_heap)
3255 (round_heap): Use DWORD_PTR, ptrdiff_t and size_t instead of
3256 DWORD, long, and unsigned long, for compatibility with x64.
3257 (allocate_heap) [_WIN64]: Reserve 32GB of memory.

3435 (handle_profiler_signal): Rename from sigprof_handler_1,
3436 for consistency with other handlers. Do not check whether
3437 cpu_log is a hash-table if garbage collecting, since it

3440 for consistency with other handlers.
3441 (setup_cpu_timer): New function, with much of what used to be in

3443 Prefer timer_settime if available, and prefer
3444 thread cputime clocks, then process cputime clocks, then
3445 monotonic clocks, to the old realtime clock. Use make_timeval
3446 to round more-correctly when falling back to setitimer.
3447 (Fprofiler_cpu_start): Use it.
3448 (Fprofiler_cpu_stop): Prefer timer_settime if available.

3718 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3720 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3721 fatal_error_backtrace.
3723 * w32proc.c (sys_kill): Undo last change: don't do anything when
3724 invoked to deliver SIGABRT to our own process. This is now
3725 handled by emacs_raise.
3727 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3729 * w32term.c (w32_read_socket): Remove leftover reference to
3730 interrupt_input_pending.
3732 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3734 Do not use SA_NODEFER.
3735 Problem reported by Dani Moncayo in
3736 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3738 * sysdep.c (emacs_abort): Do not reset signal handler.
3739 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3740 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3741 wanted even on POSIXish hosts, and it doesn't work on Windows.
3743 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3745 * xterm.c (x_term_init): Call fixup_locale before and after calling
3746 gtk_init (Bug#12392).
3748 2012-09-23 Chong Yidong <cyd@gnu.org>
3750 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3751 Vdynamic_library_alist.
3753 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3754 (Fgnutls_available_p): Caller changed.
3756 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3757 (Flibxml_parse_xml_region): Likewise.
3759 * dispextern.h (struct image_type): Remove arg from init function.
3761 * image.c (Finit_image_library, lookup_image_type)
3762 (define_image_type): Remove now-unneeded second arg.
3763 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3764 (init_tiff_functions, init_gif_functions, init_svg_functions):
3765 Arglist and w32_delayed_load calling convention changed.
3766 (gs_type): Remove init_gs_functions; there is no such function.
3767 (valid_image_p, make_image): Fix caller to lookup_image_type.
3769 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3771 Simplify and avoid signal-handling races (Bug#12471).
3773 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3774 Avoid recursive loop if there's a fatal error in the function itself.
3775 * atimer.c (pending_atimers):
3776 * blockinput.h: Don't include "atimer.h"; no longer needed.
3777 (interrupt_input_pending): Remove. All uses removed.
3778 pending_signals now counts both atimers and ordinary interrupts.
3779 This is less racy than having three separate pending-signal flags.
3780 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3782 Rename from their upper-case counterparts BLOCK_INPUT,
3783 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3784 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3785 This makes it easier to access volatile variables more accurately.
3786 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3787 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3788 that's more reliable if the code is buggy and sets
3789 interrupt_input_blocked to a negative value. All uses changed.
3790 * atimer.c (deliver_alarm_signal):
3791 Remove. No need to deliver this to the parent; any thread can
3792 handle this signal now. All uses replaced by underlying handler.
3793 * atimer.c (turn_on_atimers):
3794 * dispnew.c (handle_window_change_signal):
3795 * emacs.c (handle_danger_signal):
3796 * keyboard.c (kbd_buffer_get_event):
3797 Don't reestablish signal handler; not needed with sigaction.
3798 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3800 Rework to avoid unnecessary accesses to volatile variables.
3801 (UNBLOCK_INPUT_TO): Now a function.
3802 (totally_unblock_input, unblock_input): New decls.
3803 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3804 (init_data): Remove. Necessary stuff now done in init_signal.
3805 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3806 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3807 (fatal_error_code): Remove; no longer needed.
3808 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3809 it doesn't always backtrace. All uses changed. No need to reset
3810 signal to default, since sigaction and/or die does that for us now.
3811 Use emacs_raise (FOO), not kill (getpid (), FOO).
3812 (main): Check more-accurately whether we're dumping.
3813 Move fatal-error setup to sysdep.c
3814 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3815 * gtkutil.c (xg_get_file_name, xg_get_font):
3816 Remove no-longer-needed signal-mask manipulation.
3817 * keyboard.c, process.c (POLL_FOR_INPUT):
3818 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3819 * keyboard.c (read_avail_input): Remove.
3820 All uses replaced by gobble_input.
3821 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3822 (kbd_buffer_store_event_hold, gobble_input):
3823 (record_asynch_buffer_change) [USABLE_SIGIO]:
3824 (store_user_signal_events):
3825 No need to mess with signal mask.
3826 (gobble_input): If blocking input and there are terminals, simply
3827 set pending_signals to 1 and return. All hooks changed to not
3828 worry about whether input is blocked.
3829 (process_pending_signals): Clear pending_signals before processing
3830 them, in case a signal comes in while we're processing.
3831 By convention callers now test pending_signals before calling us.
3832 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3833 New functions, to support changes to blockinput.h.
3834 (handle_input_available_signal): Now extern.
3835 (reinvoke_input_signal): Remove. All uses replaced by
3837 (quit_count): Now volatile, since a signal handler uses it.
3838 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3839 All callers changed. Block SIGINT only if not already blocked.
3840 Clear sigmask reliably, even if Fsignal returns, which it can.
3841 Omit unnecessary accesses to volatile var.
3842 (quit_throw_to_read_char): No need to restore sigmask.
3843 * keyboard.c (gobble_input, handle_user_signal):
3844 * process.c (wait_reading_process_output):
3845 Call signal-handling code rather than killing ourselves.
3846 * lisp.h: Include <float.h>, for...
3847 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3848 (pending_signals): Now volatile.
3849 (syms_of_data): Now const if IEEE floating point.
3850 (handle_input_available_signal) [USABLE_SIGIO]:
3851 (terminate_due_to_signal, record_child_status_change): New decls.
3852 * process.c (create_process): Avoid disaster if memory is exhausted
3853 while we're processing a vfork, by tightening the critical section
3855 (send_process_frame, process_sent_to, handle_pipe_signal)
3856 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3858 (send_process): No need for setjmp/longjmp any more, since the
3859 SIGPIPE stuff is now gone. Instead, report an error if errno
3861 (record_child_status_change): Now extern. PID and W are now args.
3862 Return void, not bool. All callers changed.
3863 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3864 Remove. All uses removed. This bug should be fixed now in a
3866 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3867 and record the child status change directly. This avoids the
3868 need to futz with the signal mask.
3869 (process_fatal_action): Move here from emacs.c.
3870 (emacs_sigaction_flags): New function, containing
3871 much of what used to be in emacs_sigaction_init.
3872 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3873 caught by emacs, to make races less likely.
3874 (deliver_process_signal): Rename from handle_on_main_thread.
3876 (BACKTRACE_LIMIT_MAX): Now at top level.
3877 (thread_backtrace_buffer, threadback_backtrace_pointers):
3879 (deliver_thread_signal, deliver_fatal_thread_signal):
3880 New functions, for more-accurate delivery of thread-specific signals.
3881 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3882 (deliver_arith_signal): Handle in this thread, not
3883 in the main thread, since it's triggered by this thread.
3884 (maybe_fatal_sig): New function.
3885 (init_signals): New arg DUMPING so that we can be more accurate
3886 about whether we're dumping. Caller changed.
3887 Treat thread-specific signals differently from process-general signals.
3888 Block all signals while handling fatal error; that's safer.
3889 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3891 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3892 Ignore SIGPIPE unless batch.
3893 (emacs_backtrace): Output backtrace for the appropriate thread,
3894 which is not necessarily the main thread.
3895 * syssignal.h: Include <stdbool.h>.
3896 (emacs_raise): New macro.
3897 * xterm.c (x_connection_signal): Remove; no longer needed
3898 now that we use sigaction.
3899 (x_connection_closed): No need to mess with sigmask now.
3900 (x_initialize): No need to reset SIGPIPE handler here, since
3901 init_signals does this for us now.
3903 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3905 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3906 background rect may be larger (Bug#12245).
3908 2012-09-23 Chong Yidong <cyd@gnu.org>
3910 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3912 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3914 * .gdbinit: Just stop at fatal_error_backtrace.
3915 See Stefan Monnier's request in
3916 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3917 Remove no-longer-used query of system type.
3919 2012-09-22 Chong Yidong <cyd@gnu.org>
3921 * search.c (Freplace_match): Doc fix (Bug#12325).
3923 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3925 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3926 (Fline_end_position): Doc fix.
3928 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3930 2012-09-22 Chong Yidong <cyd@gnu.org>
3932 * dispextern.h (struct image_type): Add new slot, storing a type
3933 initialization function.
3935 * image.c (define_image_type): Call the image initializer function
3936 if it is defined. Arguments and return value changed.
3937 (valid_image_p, make_image): Callers changed.
3938 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3939 (gif_type, imagemagick_type, svg_type, gs_type):
3940 Add initialization functions.
3941 (Finit_image_library): Call lookup_image_type.
3942 (CHECK_LIB_AVAILABLE): Macro deleted.
3943 (lookup_image_type): Call define_image_type here, rather than via
3944 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3945 (syms_of_image): Move define_image_type calls for xbm_type and
3946 pbm_type to lookup_image_type.
3948 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3950 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3951 'idle_timers' from here ...
3952 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3953 lists, to avoid infloops when the timer does something stupid,
3954 like reinvoke itself with the same or smaller time-out.
3957 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3959 * window.c (Fsplit_window_internal): Handle only Qt value of
3960 Vwindow_combination_limit separately.
3961 (Qtemp_buffer_resize): New symbol.
3962 (Vwindow_combination_limit): New default value.
3965 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3967 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3968 the new overlay string. (Bug#10159)
3970 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3972 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3973 or that fprintf is async-signal-safe. POSIX doesn't require
3976 2012-09-22 Chong Yidong <cyd@gnu.org>
3978 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3981 2012-09-22 Kenichi Handa <handa@gnu.org>
3983 * composite.c (composition_reseat_it): Handle the case that a
3984 grapheme cluster is not covered by a single font (Bug#12352).
3986 2012-09-21 Chong Yidong <cyd@gnu.org>
3988 * image.c (define_image_type): Avoid adding duplicate types to
3989 image_types (Bug#12463). Suggested by Jörg Walter.
3991 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3993 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3994 (print_load_command_name): Add case LC_DATA_IN_CODE.
3995 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3997 2012-09-21 Glenn Morris <rgm@gnu.org>
3999 * eval.c (Frun_hook_with_args_until_success)
4000 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4002 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4004 * fileio.c (Ffile_selinux_context): Only call freecon when
4005 lgetfilecon succeeded.
4006 (Fset_file_selinux_context): Likewise. (Bug#12444)
4008 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4010 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4011 reordering, locate the cursor by calling set_cursor_from_row; if
4012 that fails, clear the desired glyph matrix before returning a
4013 failure indication to the caller. Fixes leaving garbled display
4014 when fast scrolling with a down-key. (Bug#12403)
4015 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4016 scrolling through multibyte text.
4018 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4020 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4021 calling mark_vectorlike since that's the one that marks the window.
4022 (mark_discard_killed_buffers): Mark the final cdr.
4023 * window.h (struct window): Move prev/next_buffers to the
4024 non-standard fields.
4025 * window.c (make_window): Initialize prev/next_buffers manually.
4027 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4029 Omit unused arg EXPECTED from socket hooks.
4030 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4031 * nsterm.m (ns_term_init):
4032 * termhooks.h (struct terminal.read_socket_hook):
4033 * w32inevt.c (w32_console_read_socket):
4034 * w32term.c (w32_read_socket):
4035 * xterm.c (XTread_socket):
4036 Omit unused arg EXPECTED. All callers changed.
4037 (store_user_signal_events): Return void, not int, since callers no
4038 longer care about the return value. All uses changed.
4040 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4042 * w32gui.h (XParseGeometry): Do not declare.
4044 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4046 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4047 Ignore 'expected'. See Eli Zaretskii in
4048 <http://bugs.gnu.org/12471#8> (last line).
4050 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4051 (XParseGeometry): Now static. Substitute extremal values for
4052 values that are out of range.
4054 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4056 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4058 * nsfns.m (XParseGeometry): Remove.
4059 (Fx_create_frame): Call x_set_offset to correctly interpret
4060 top_pos in geometry.
4062 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4063 (Fx_parse_geometry): If there is a space in string, call
4064 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4066 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4068 * search.c (scan_buffer): Use character positions in calls to
4069 region_cache_forward and region_cache_backward, not byte
4070 positions. (Bug#12196)
4072 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4073 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4075 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4076 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4077 emacs_blocked_malloc, now deleted.
4079 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4081 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4082 The workaround was for improving performance on Solaris 2.4, but
4083 is getting in the way now. Emacs will still work if someone is
4084 still running Solaris 2.4 in a museum somewhere; Sun dropped
4085 support for Solaris 2.4 in 2003.
4086 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4087 * process.c (create_process) [HAVE_WORKING_VFORK]:
4088 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4089 since Emacs no longer uses vfork on that platform.
4091 2012-09-17 Glenn Morris <rgm@gnu.org>
4093 * emacs.c: Use COPYRIGHT.
4095 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4097 Remove configure's --without-sync-input option (Bug#12450).
4098 When auditing signal-handling in preparation for cleaning it up,
4099 I found that SYNC_INPUT has race conditions and would be a real
4100 pain to fix. Since it's an undocumented and deprecated
4101 configure-time option, now seems like a good time to remove it.
4102 Also see <http://bugs.gnu.org/11080#16>.
4103 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4104 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4105 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4106 (malloc_hysteresis):
4107 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4108 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4109 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4110 (dont_register_blocks, bytes_used_when_reconsidered)
4111 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4112 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4113 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4114 Remove. All uses removed.
4115 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4116 implementation, one that depends on whether the new macro
4117 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4119 * atimer.c (run_timers, handle_alarm_signal):
4120 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4121 (handle_async_input, process_pending_signals)
4122 (handle_input_available_signal, init_keyboard):
4123 * nsterm.m (ns_read_socket):
4124 * process.c (wait_reading_process_output):
4125 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4126 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4128 * xterm.c (XTread_socket):
4130 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4131 * eval.c (handling_signal): Remove. All uses removed.
4132 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4133 All uses replaced with the SYNC_INPUT version.
4134 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4136 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4139 * font.c (Ffont_shape_gstring): Remove unused local.
4141 2012-09-16 Glenn Morris <rgm@gnu.org>
4143 * Makefile.in (clean): No longer run nextstep's clean.
4145 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4147 (ns-app): Move here from ns.mk, and simplify.
4148 (clean): Simplify nextstep entry.
4149 * ns.mk: Remove file.
4151 2012-09-17 Kenichi Handa <handa@gnu.org>
4153 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4154 not covert the last few charactes.
4156 2012-09-16 Kenichi Handa <handa@gnu.org>
4158 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4159 here, but just check the validity of glyphs in the glyph-string.
4161 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4163 * window.c (Fwindow_parameter, Fset_window_parameter):
4164 Accept any window as argument (Bug#12452).
4166 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4168 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4169 to ns_term_init to avoid memory leak.
4171 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4172 explicit retain/release.
4173 (ns_term_init): Only allow one display. Initialize outerpool and
4176 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4178 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4179 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4180 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4181 the Microsoft problem in a different way, by altering ../nt/config.nt.
4183 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4198 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4199 by lisp.h. This completes removal of setjmp.h inclusion
4200 erroneously announced in the previous commit. (Bug#12446)
4202 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4205 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4206 not defined as a macro. The latter happens on MS-Windows.
4209 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4211 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4212 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4213 Some instances of '#include <setjmp.h>' removed, if the
4214 only reason for the instance was because "lisp.h" was included.
4215 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4216 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4217 and _longjmp with the new symbols. Emacs already uses _setjmp if
4218 available, so this change affects only POSIXish hosts that have
4219 sigsetjmp but not _setjmp, such as some versions of Solaris and
4220 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4221 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4222 (png_load_body) [HAVE_PNG]:
4223 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4224 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4225 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4226 since PNG requires jmp_buf. This is the only exception to the
4227 general rule that we now use sys_setjmp and sys_longjmp.
4228 This exception is OK since this code does not change the signal
4229 mask or longjmp out of a signal handler.
4231 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4233 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4234 Include "syssignal.h", for 'main_thread'.
4236 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4238 Avoid out-of-range marker position (Bug#12426).
4239 * insdel.c (replace_range, replace_range_2):
4240 Adjust markers before overlays, as suggested by comments.
4241 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4242 Remove redundant check before calling offset_intervals.
4244 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4246 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4247 current buffer (Bug#12387).
4249 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4251 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4253 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4255 Use a more backwards-compatible timer format (Bug#12430).
4256 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4257 vector element, not from the 4th, since PSECS is now at the end.
4258 (Fcurrent_idle_time): Doc fix.
4260 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4262 Function to mark objects and remove killed buffers at once.
4263 * alloc.c (discard_killed_buffers): Rename to ...
4264 (mark_discard_killed buffers) ... new name. Add marking
4265 of remaining objects. Fix comment. Adjust users.
4266 (mark_object): Do not touch frame buffer lists here.
4267 * frame.c (delete_frame): Reset frame buffer lists here.
4269 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4271 Better workaround for GNOME bug when --enable-gcc-warnings.
4272 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4273 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4274 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4276 Simplify SIGIO usage (Bug#12408).
4277 The code that dealt with SIGIO was crufty and confusing, e.g., it
4278 played tricks like "#undef SIGIO" but these tricks were not used
4279 consistently. Simplify mostly by not #undeffing standard symbols,
4280 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4281 or not as we please) rather than "defined SIGIO" (standard symbol
4282 that we probably shouldn't #undef).
4283 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4284 Modules that need it can include it.
4285 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4286 * dispextern.h (ignore_sigio): New decl.
4287 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4288 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4289 * emacs.c (shut_down_emacs):
4290 * keyboard.c (kbd_buffer_store_event_hold):
4291 Use ignore_sigio rather than invoking 'signal' directly.
4292 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4294 (FIONREAD, SIGIO): Do not #undef.
4295 (tty_read_avail_input): Use #error rather than a syntax error.
4296 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4297 for I_PIPE, used by SETUP_SLAVE_PTY.
4298 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4299 * sysdep.c (croak): Remove; no longer needed. This bit of
4300 temporary code, with Fred N. Fish's comment that it's temporary,
4301 has been in Emacs since at least 1992!
4302 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4303 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4304 * syssignal.h (croak): Remove decl.
4305 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4306 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4307 now that we're termios-only.
4308 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4309 * term.c (dissociate_if_controlling_tty): Use #error rather than
4312 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4313 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4314 to work around GNOME bug 683906.
4315 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4316 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4317 This works around GCC bug 54561.
4319 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4321 More fixes for 'volatile' and setjmp/longjmp.
4322 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4323 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4324 (png_load_body) [HAVE_PNG]:
4325 (jpeg_load_body) [HAVE_JPEG]:
4326 New function, with most of the old parent function's body.
4327 (png_load) [HAVE_PNG]:
4328 (jpeg_load) [HAVE_JPEG]:
4329 Invoke the new function, to avoid longjmp munging our locals.
4330 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4331 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4332 longjmp is passed 2, as the C standard doesn't guarantee this.
4333 Instead, store the failure code into mgr->failure_code.
4335 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4337 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4338 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4339 (syms_of_keyboard): Remove support for unread-command-char.
4341 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4343 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4344 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4345 violation. (Bug#12426)
4347 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4349 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4351 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4353 * eval.c: Add `inhibit-debugger'.
4354 (Qinhibit_debugger): New symbol.
4355 (call_debugger): Bind it instead of Qdebug_on_error.
4356 (maybe_call_debugger): Test Vinhibit_debugger.
4357 (syms_of_eval): Define inhibit-debugger.
4358 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4359 (syms_of_xdisp): Remove inhibit-debug-on-message.
4361 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4363 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4364 If a nonvolatile local variable is written before a _longjmp to
4365 the frame containing the variable, and is read after the _longjmp,
4366 the value read is indeterminate. Some local variables of type
4367 'struct handler' and 'struct catchtag' are used in this way, so
4368 mark each of their slots as volatile if the slot can be set before
4369 _longjmp and read afterwards.
4370 * lisp.h (struct handler): var and chosen_clause are now volatile.
4371 (struct catchtag): val, next, and pdlcount are now volatile.
4373 * bidi.c (bidi_push_it, bidi_pop_it):
4374 * fns.c (copy_hash_table):
4375 * image.c (define_image_type):
4376 * keyboard.c (kbd_buffer_store_event_hold):
4377 * process.c (Fprocess_send_eof):
4378 * xfaces.c (x_create_gc) [HAVE_NS]:
4379 * xgselect.c (xg_select):
4380 Prefer assignment to memcpy when either will do.
4382 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4383 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4384 time an item is removed. No need to mark this function 'inline';
4385 the compiler knows better than we do.
4387 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4389 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4390 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4391 to change_frame_size (Bug#12388).
4392 (windowDidResize:): Pass YES to updateFrameSize.
4394 * nsterm.h: Add delay parameter to updateFrameSize.
4396 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4398 Discard killed buffers from deleted window and frame objects.
4399 This reduces an amount of references to killed buffers and
4400 helps GC to reclaim them faster.
4401 * alloc.c (discard_killed_buffers): New function.
4402 (mark_object): Use it for deleted windows and frames.
4403 (mark_object): If symbol's value is set up for a killed buffer
4404 or deleted frame, restore its global binding.
4405 * data.c (swap_in_global_binding): Add GC notice.
4406 (swap_in_symval_forwarding): Use convenient set_blv_where.
4407 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4408 * window.h: ... to here.
4410 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4412 Convenient macro to check whether the buffer is live.
4413 * buffer.h (BUFFER_LIVE_P): New macro.
4414 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4415 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4417 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4419 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4420 composition cases (Bug#12364).
4422 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4423 overhang of succeeding glyphs overlapping box cursor.
4425 * w32term.c (x_draw_glyph_string): Likewise.
4427 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4429 Simplify, document, and port floating-point (Bug#12381).
4430 The porting part of this patch fixes bugs on non-IEEE platforms
4431 with frexp, ldexp, logb.
4432 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4434 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4435 support, by removing commented-out code and briefly listing the
4436 C89 functions excluded. The commented-out stuff was confusing
4437 maintenance, e.g., we thought we needed cbrt but it was commented out.
4438 (logb): Remove decl; no longer needed.
4439 (isfinite): New macro, if not already supplied.
4440 (isnan): Don't replace any existing macro.
4441 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4442 are present on all C89 platforms.
4443 (Ffrexp): Do not special-case zero, as frexp does the right thing
4445 (Flogb): Do not use logb, as it doesn't have the desired meaning
4446 on hosts that use non-base-2 floating point. Instead, stick with
4447 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4448 frexp, to avoid getting an unspecified result.
4450 * xdisp.c (Qinhibit_debug_on_message): Now static.
4452 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4454 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4455 NSBezierPath (Bug#12131).
4457 2012-09-10 Chong Yidong <cyd@gnu.org>
4459 * fns.c (Fdelq, Fdelete): Doc fix.
4461 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4463 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4464 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4466 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4468 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4469 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4472 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4474 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4475 left fringe if the window has a left margin. This avoids leaving
4476 traces of the cursor because its leftmost pixel is not drawn over.
4478 * dispnew.c (update_window_line): When the left margin area of a
4479 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4480 that screen line. (Bug#12277)
4482 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4484 Assume C89 or later for math functions (Bug#12381).
4485 This simplifies the code, and makes it a bit smaller and faster,
4486 and (most important) makes it easier to clean up signal handling
4487 since we can stop worring about floating-point exceptions in
4488 library code. That was a problem before C89, but the problem
4489 went away many years ago on all practical Emacs targets.
4490 * data.c, image.c, lread.c, print.c:
4491 Don't include <math.h>; no longer needed.
4492 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4493 might be autoconfigured, as that never happens.
4495 * doprnt.c (DBL_MAX_10_EXP):
4496 * print.c (DBL_DIG):
4497 Remove. C89 or later always defines these.
4498 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4499 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4500 (arith_error, domain_error, domain_error2):
4501 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4502 no longer needed -- we simply return what C returns. All uses removed.
4503 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4505 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4506 Remove. All uses expanded, as these macros are no longer used
4507 more than once and are now more trouble than they're worth.
4508 (Ftan): Use tan, not sin / cos.
4509 (Flogb): Assume C89 frexp.
4510 (fmod_float): Assume C89 fmod.
4511 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4512 (init_floatfns): Remove. All uses removed.
4514 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4516 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4517 compositeToPoint for OSX < 10.6 (Bug#12390).
4519 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4521 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4522 This produces more-accurate results.
4524 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4526 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4527 changes (Bug#12088).
4529 2012-09-08 Chong Yidong <cyd@gnu.org>
4531 * syntax.c (Fstring_to_syntax): Doc fix.
4533 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4535 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4536 in the internal border.
4537 (x_set_window_size): Remove static variables and their usage.
4538 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4539 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4540 Remove fringe/internal border adjustment (Bug#11052).
4541 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4542 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4543 (ns_fix_rect_ibw): Remove.
4544 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4545 (ns_dumpglyphs_box_or_relief): Ditto.
4546 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4548 (ns_dumpglyphs_image): Ditto.
4549 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4551 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4552 their usage. Add fringe_extended_p and its use as in other terms.
4553 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4554 scroll bar was removed.
4555 (updateFrameSize): New function.
4556 (windowDidResize): Move code to updateFrameSize and call it.
4558 * nsterm.h (EmacsView): Add updateFrameSize.
4560 2012-09-07 Chong Yidong <cyd@gnu.org>
4562 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4564 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4566 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4568 More signal-handler cleanup (Bug#12327).
4569 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4570 Problem introduced when merging patches. Noted by Eli Zaretskii in
4571 <http://bugs.gnu.org/12327#67>.
4572 * floatfns.c: Comment fix.
4573 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4574 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4575 and anyway the declaration is harmless even if SIGDANGER is not defined.
4576 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4577 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4578 source files not surprisingly expected syssignal.h to define, or
4579 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4580 Include <sys/ioctl.h>, for FIONREAD.
4581 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4582 This eliminates a problem whereby other files mysteriously had
4583 to include "syssignal.h" before including "systty.h" if they
4584 wanted to use "#ifdef SIGIO".
4586 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4588 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4590 * w32.c (sigemptyset): Empty the set.
4591 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4593 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4595 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4597 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4598 (mark_object): Likewise for frame objects.
4600 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4602 * syssignal.h (handle_on_main_thread): Always declare,
4603 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4604 This ports to platforms without HAVE_PTHREAD.
4606 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4608 Signal-handler cleanup (Bug#12327).
4609 Emacs's signal handlers were written in the old 4.2BSD style with
4610 sigblock and sigmask and so forth, and this led to some
4611 inefficiencies and confusion. Rewrite these to use
4612 pthread_sigmask etc. without copying signal sets around. Also,
4613 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4614 'signal', and instead use functions that do not attempt to take
4615 over the system name space. This patch causes Emacs's text
4616 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4617 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4618 Do not include <signal.h> or "syssignal.h", as these
4619 modules do not use signals.
4620 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4621 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4622 Do not include <signal.h>, as "syssignal.h" does that for us now.
4623 * atimer.c (sigmask_atimers): New function.
4624 (block_atimers, unblock_atimers): New functions,
4625 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4627 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4628 no longer needed here.
4629 * emacs.c (main): Inspect existing signal handler with sigaction,
4630 so that there's no need to block and unblock SIGHUP.
4631 * sysdep.c (struct save_signal): New member 'action', replacing
4632 old member 'handler'.
4633 (save_signal_handlers, restore_signal_handlers):
4634 Use sigaction instead of 'signal' to save and restore.
4635 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4636 New function. All users of 'signal' modified to use set_sighandler
4637 if they're writeonly, and to use sys_signal if they're read+write.
4638 (emacs_sigaction_init, forwarded_signal): New functions.
4639 (sys_signal): Remove. All uses replaced by calls to sigaction
4640 and emacs_sigaction_init, or by direct calls to 'signal'.
4641 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4642 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4643 all uses replaced by pthread_sigmask etc. calls.
4644 * syssignal.h: Include <signal.h>.
4645 (emacs_sigaction_init, forwarded_signal): New decls.
4646 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4647 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4648 (sigmask, sys_sigmask): Remove; no longer needed.
4649 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4650 (sigblock, sigunblock, sigfree):
4651 (sigsetmask) [!defined sigsetmask]:
4652 Remove. All uses replaced by pthread_sigmask.
4653 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4654 no longer need to be replaced, and its typical old uses
4655 are now done via emacs_sigaction_init and sigaction.
4656 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4657 (sys_sigdel): Remove; unused.
4658 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4660 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4662 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4663 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4665 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4667 Explicitly mark buffer_defaults and buffer_local_symbols.
4668 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4669 mark_local_symbols here.
4670 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4671 since special buffers aren't marked here any more.
4672 (allocate_buffer): Chain new buffer with all_buffers here...
4673 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4675 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4676 (syms_of_buffer): Remove staticpro of the above.
4677 (init_buffer_once): Set names for buffer_defaults and
4678 buffer_local_symbols.
4680 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4682 Use bool for booleans in font-related modules.
4683 * font.c (font_intern_prop, font_style_to_value)
4684 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4685 (generate_otf_features, font_check_otf_features, font_check_otf)
4686 (font_match_p, font_list_entities, font_at):
4687 * fontset.c (fontset_id_valid_p, reorder_font_vector
4688 (fontset_find_font, Fset_fontset_font)
4689 (face_suitable_for_char_p) [0]:
4690 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4691 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4692 (m17n_flt_initialized, ftfont_shape_by_flt):
4693 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4694 * nsfont.m (nsfont_draw):
4695 * w32font.c (w32font_draw):
4696 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4697 Use bool for booleans.
4698 * font.h: Adjust to above API changes.
4699 (struct font, struct font_driver, struct font_driver_list):
4700 Use bool for booleans.
4701 (struct font): Remove useless member encoding_type.
4703 * fontset.c, xftfont.c: Omit unnecessary static decls.
4705 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4707 * alloc.c (mark_object): Revert window marking code
4708 since it's unsafe for the Fset_window_configuration.
4710 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4712 Fix race conditions with signal handlers and errno (Bug#12327).
4713 Be more systematic about preserving errno whenever a signal
4714 handler returns, even if it's not in the main thread. Do this by
4715 renaming signal handlers to distinguish between signal delivery
4716 and signal handling. All uses changed.
4717 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4718 * data.c (deliver_arith_signal): Rename from arith_error.
4719 * dispnew.c (deliver_window_change_signal): Rename from
4720 window_change_signal.
4721 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4722 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4723 * keyboard.c (deliver_input_available_signal): Rename from
4724 input_available_signal.
4725 (deliver_user_signal): Rename from handle_user_signal.
4726 (deliver_interrupt_signal): Rename from interrupt_signal.
4727 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4728 (deliver_child_signal): Rename from sigchld_handler.
4729 * atimer.c (handle_alarm_signal):
4730 * data.c (handle_arith_signal):
4731 * dispnew.c (handle_window_change_signal):
4732 * emacs.c (handle_fatal_signal, handle_danger_signal):
4733 * keyboard.c (handle_input_available_signal):
4734 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4735 * process.c (handle_pipe_signal, handle_child_signal):
4736 New functions, with the actual signal-handling code taken from the
4737 original respective signal handlers, sans the sporadic attempts to
4738 preserve errno, since that's now done by handle_on_main_thread.
4739 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4740 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4741 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4743 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4744 Move initialization of main_thread to sysdep.c's init_signals.
4745 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4746 our usage, and simplifies the mainline code.
4747 (record_child_status_change): New static function, as a helper
4748 for handle_child_signal, and with most of the old child handler's
4750 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4751 (handle_child_signal): Use the above.
4752 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4753 Moved here from emacs.c.
4754 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4755 code moved here from emacs.c's main function.
4756 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4757 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4758 This lets callers save and restore errno properly.
4760 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4762 Remove redundant or unused things here and there.
4763 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4764 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4765 * editfns.c (Fcompare_buffer_substrings): Likewise.
4766 * frame.h (struct terminal, struct font_driver_list):
4767 Remove redundant declarations.
4768 * window.h (Qleft, Qright): Likewise.
4770 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4772 Do not mark objects from deleted buffers, windows and frames.
4773 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4774 (mark_object): Likewise for windows and frames.
4776 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4778 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4779 buffer_defaults and buffer_local_symbols as valid objects.
4780 Return special value to denote them.
4782 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4784 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4785 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4786 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4787 (file_name_absolute_p, Fsubstitute_in_file_name):
4788 (check_executable, check_writable, Ffile_accessible_directory_p)
4789 (Fset_file_selinux_context, Fdefault_file_modes)
4790 (Finsert_file_contents, choose_write_coding_system)
4791 (Fwrite_region, build_annotations, a_write, e_write)
4793 * filelock.c (boot_time_initialized, get_boot_time)
4794 (get_boot_time_1, lock_file_1, within_one_second):
4795 * floatfns.c (in_float):
4796 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4797 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4798 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4799 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4800 * window.c (compare_window_configurations):
4801 Use bool for booleans.
4802 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4803 (Fdefault_file_modes): Now mode_t, not int, for modes.
4804 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4805 (internal_delete_file): Now returns void, not a (boolean) int,
4806 since nobody was looking at the return value.
4807 * lisp.h, window.h: Adjust to above API changes.
4809 * xdisp.c (set_message): Simplify and reindent last change.
4811 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4813 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4815 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4817 * eval.c (call_debugger): Make the function non-static so that we
4818 can call it from set_message.
4820 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4821 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4823 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4825 Give more-useful info on a fatal error (Bug#12328).
4826 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4827 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4828 of doing the work ourselves.
4829 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4830 do most of the work.
4831 (fatal_error_backtrace): New function, taken from the guts
4832 of the old fatal_error_signal, but with a new option to output
4834 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4835 info about the signal than just its number.
4836 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4837 * sysdep.c: Include <execinfo.h>
4838 (emacs_backtrace): New function, taken partly from the previous
4839 code of the 'die' function.
4840 (emacs_abort): Call fatal_error_backtrace rather than abort.
4842 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4844 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4845 eager (load-time) macro-expansion.
4846 * lisp.mk (lisp): Add macroexp.
4848 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4850 Simplify redefinition of 'abort' (Bug#12316).
4851 Do not try to redefine the 'abort' function. Instead, redo
4852 the code so that it calls 'emacs_abort' rather than 'abort'.
4853 This removes the need for the NO_ABORT configure-time macro
4854 and makes it easier to change the abort code to do a backtrace.
4855 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4856 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4857 Remove; sysdep.c's emacs_abort now takes its place.
4858 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4859 'abort' changed to use 'emacs_abort'.
4860 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4861 (abort) [!defined abort]: Rename to ...
4862 (emacs_abort): ... new name.
4863 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4864 the place of the old 'abort' in emacs.c.
4865 * w32.c, w32fns.c (abort): Do not #undef.
4866 * w32.c (emacs_abort): Rename from w32_abort.
4868 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4870 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4871 offsets[j].dv, since the y axis of the screen coordinates points
4872 down, while the y axis of the font definition coordinates points
4873 up. This fixes display of Arabic diacritics such as KASRA and
4874 KASRATAN. (Bug#11860)
4876 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4878 Be more systematic about _setjmp vs setjmp.
4879 * alloc.c (test_setjmp, mark_stack):
4880 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4881 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4882 (png_load, my_error_exit, jpeg_load):
4883 * process.c (send_process_trap, send_process):
4884 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4885 The underscored versions are up to 30x faster on some hosts.
4886 Formerly, the code used setjmp+longjmp sometimes and
4887 _setjmp+_longjmp at other times, with no particular reason to
4888 prefer setjmp+longjmp.
4890 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4892 Fix minor problem found by static checking.
4893 * buffer.c (Fdelete_all_overlays): Return nil.
4895 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4897 * buffer.c (Fdelete_all_overlays): New function.
4899 2012-09-03 Chong Yidong <cyd@gnu.org>
4901 * gtkutil.c: Add extern decl for Qxft.
4903 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4905 * emacs.c, eval.c: Use bool for boolean.
4906 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4907 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4908 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4909 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)

4912 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4913 (maybe_call_debugger, Fbacktrace):
4914 * process.c (read_process_output, exec_sentinel):
4915 Use bool for booleans.
4916 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4917 All callers changed.
4918 * eval.c (interactive_p): Omit always-true boolean argument
4919 EXCLUDE_SUBRS_P. All callers changed.
4920 * dispextern.h, lisp.h: Reflect above API changes.
4921 * firstfile.c (dummy): Use the address of 'main', whose signature
4922 won't change, instead of the address of 'initialize', whose
4923 signature just changed from int to bool.
4924 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4925 * msdos.c (fatal_error_in_progress): ... from here.
4926 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4928 (redisplay_internal, unwind_redisplay): Simply clear
4929 REDISPLAYING_P when unwinding, instead of saving its previous,
4930 always-false value and then restoring it.
4932 Clean up some extern decls.
4933 Mostly, this hoists extern decls out of .c files and into .h files.
4934 That way, we're more likely to catch errors if the interfaces change.
4935 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4936 declare xg_mark_data.
4937 * dispextern.h (x_frame_parm_handlers):
4939 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4940 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4941 (Qultra_bold, Qoblique, Qitalic):
4942 Move extern decl here from .c file.
4943 * alloc.c (xg_mark_data) [USE_GTK]:
4945 * eval.c (Qlexical_binding):
4946 * fns.c (time) [!HAVE_UNISTD_H]:

4952 * process.c (QCfamily, QCfilter):
4953 * widget.c (free_frame_faces):

4955 * xfont.c (x_clear_errors):
4956 * xterm.c (x_frame_parm_handlers):
4957 Remove now-redundant extern decls.
4958 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4959 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4961 * xfaces.c: Remove unnecessary static decls.
4962 * xterm.c (updating_frame): Remove decl of nonexistent object.
4964 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4965 when building globals.h, as the objects that are not built on
4966 this host are not needed to compile C files on this host.
4968 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4970 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4972 * frame.h: Add missing prototype for x_wm_set_size_hint.
4974 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4999 Use bool for boolean.
5000 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5001 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5003 2012-09-02 Chong Yidong <cyd@gnu.org>
5005 * keymap.c (push_key_description): Print M-TAB as C-M-i
5008 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5010 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

5020 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5021 more than one grapheme cluster passed to the shaper: compute the
5022 offset adjustment values separately for each cluster. (Bug#11860)
5024 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5025 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5026 about implicit conversions from integer to pointer.
5028 2012-09-01 Daniel Colascione <dancol@dancol.org>
5030 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

5046 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
5047 x_wm_set_size_hint, x_query_colors, x_real_positions,
5048 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
5049 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
5050 all of which have been moved to common code.
5052 * xfaces.c: Include TERM_HEADER instead of listing all possible
5053 window-system headers.
5055 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

5076 * keyboard.c: Include TERM_HEADER instead of listing all possible
5077 window-system headers.
5079 * image.c: Include TERM_HEADER instead of listing all possible
5080 window-system headers. Declare Vlibrary_cache when compiling for
5083 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
5084 window system declarations.
5086 * frame.h: Move common functions here: set_frame_menubar,
5087 x_set_window_size, x_sync, x_get_focus_frame,
5088 x_set_mouse_position, x_set_mouse_pixel_position,
5089 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
5090 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
5091 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,
5092 x_activate_menubar, x_real_positions, x_bitmap_icon,
5093 x_set_menu_bar_lines, free_frame_menubar, x_free_frame_resources,
5096 * frame.c: Include TERM_HEADER instead of listing all possible
5097 window-system headers.
5099 * font.c: Include TERM_HEADER instead of listing all possible
5100 window-system headers.
5102 * emacs.c: Include TERM_HEADER.
5104 * dispnew.c: Include TERM_HEADER instead of listing all possible

5110 the current window system; include in list of objects to link into
5113 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5115 Remove mark_ttys function and fix tty_display_info initialization.
5116 * lisp.h (mark_ttys): Remove prototype.
5117 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5118 to mark_ttys because all possible values of 'top_frame' slot are
5119 the frames which are reachable from Vframe_list.
5120 * term.c (mark_ttys): Remove.
5121 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5123 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5125 Change struct frame bitfields from unsigned char to unsigned.
5126 * frame.h (struct frame): Change type of 'display_preempted',

5140 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
5141 does not become zero (Bug#12234).
5143 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
5145 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
5146 for GCC 4.7.1 x86-64.
5148 2012-08-30 Glenn Morris <rgm@gnu.org>
5150 * lread.c (init_lread): For out-of-tree builds, only add the
5151 source directory's site-lisp dir to the load-path if it exists,
5152 consistent with in-tree builds. (Bug#12302)
5154 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5156 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

5158 (windowShouldClose:): Set window_closed.
5159 (dealloc): New member, free button_values.
5160 (process_dialog:): Make member function. Remove window argument,

5170 Code formatting change.
5171 (timeout_handler:): Set timer_fired to YES.
5172 (runDialogAt:): Set timer_fired to NO.
5173 Handle click on close button as quit.
5175 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5176 Add window_closed and button_values. Add void as return value for
5177 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5178 Add process_dialog as new member.
5180 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5182 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
5183 is not one of the heaps we manage. (Bug#12242)
5185 2012-08-28 Glenn Morris <rgm@gnu.org>
5187 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

5243 (change_frame_size_1, sit_for):
5244 Use bool for boolean.
5245 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
5246 and remove last int (actually boolean) argument, which was always 0.
5247 All callers changed.

5249 * dispextern.h (struct composition_it): Use bool for boolean.
5250 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
5251 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
5252 * dired.c (file_name_completion):
5253 Use bool for boolean. (This was missed in an earlier change.)
5255 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5257 * window.c (Fset_window_configuration): Revert first part of
5260 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>

5285 Use bool for booleans.
5286 * dired.c (file_name_completion):
5287 * process.h (fd_callback):
5288 Omit int (actually boolean) argument. It wasn't being used.

5318 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5319 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5320 not a boolean 'int', since callers never look at the return value.
5321 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5322 * coding.h (decoding_buffer_size, encoding_buffer_size)
5323 (emacs_mule_string_char): Remove unused extern decls.
5324 (struct iso_2022_spec, struct coding_system):

5340 buffer doesn't appear in the selected window, go to its old
5343 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5345 Special MEM_TYPE_SPARE to denote reserved memory.
5346 * alloc.c (enum mem_type): New memory type.
5347 (refill_memory_reserve): Use new type for spare memory.
5348 This prevents live_cons_p and live_string_p from incorrect

5377 (map_sub_char_table):
5378 Use bool for boolean.
5379 * character.c (str_to_unibyte): Omit last boolean argument; it was
5380 always 0. All callers changed.
5381 * character.h, charset.h: Adjust to match previous changes.
5382 * character.h (char_printable_p): Remove decl of nonexistent function.
5383 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5384 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5385 are all boolean, so make them single-bit bitfields.
5387 * lisp.h (ASET): Remove attempt to detect side effects.
5388 It was meant to be temporary and it often doesn't work,
5389 because when IDX has side effects the behavior of IDX==IDX
5390 is undefined. See Stefan Monnier in
5391 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5393 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5395 * lisp.h (functionp): New function (extracted from Ffunctionp).
5396 (FUNCTIONP): Use it.
5397 * eval.c (Ffunctionp): Use it.
5399 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5401 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5402 as that's faster and simpler than static storage. Don't bother
5403 with the g_main_context_query overhead if g_main_context_pending
5404 says no events are pending.
5405 (gfds, gfds_size): Remove these static vars.
5406 (xgselect_initialize): Remove; no longer needed.
5407 All uses and decls removed.
5409 * emacs.c (fatal_error_signal_hook): Remove.
5410 All uses removed. This leftover from old code was always 0.
5412 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5413 * casefiddle.c (casify_object, casify_region):
5414 * casetab.c (set_case_table):

5416 * category.h (CHAR_HAS_CATEGORY):
5417 Use bool for booleans, instead of int.
5419 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5421 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5423 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5425 On assertion failure, print backtrace if available.
5426 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5427 (die) [ENABLE_CHECKING]: Print a backtrace if available.

5436 * lisp.h (USE_SAFE_ALLOCA):
5437 Use bool for booleans, instead of int.
5438 * lisp.h, process.h: Adjust prototypes to match above changes.
5439 * callint.c (Fcall_interactively): Don't assume the mark's
5440 offset fits in 'int'.
5442 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5444 * buffer.c, buffer.h: Use bool for boolean.
5445 * buffer.c (reset_buffer_local_variables)

5451 (mmap_enlarge, mmap_set_vars):
5452 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5453 Use bool for booleans, instead of int.
5454 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5455 since the 1-or-0 return value is always ignored anyway.
5456 (mmap_initialized_p):
5457 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5458 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5460 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5462 * bidi.c: Use bool for boolean.
5463 This is a bit more readable, and makes the text segment of bidi.o
5464 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5465 Presumably it's faster too.

5472 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5473 Use bool for booleans, instead of int.
5474 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5475 (bidi_unshelve_cache): Adjust decls to match code.
5477 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5479 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5482 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5484 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5485 * atimer.h: Include <stdbool.h>.
5487 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5489 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5490 compile time tests instead of run time tests on systems that do
5492 (FRAME_MAC_P): Remove leftover from deleted code.
5493 * frame.c (syms_of_frame): Remove leftover from deleted code.
5495 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

5499 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5501 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5502 Otherwise, the compiler complains about (A?B:C) where B is void
5503 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5504 (fontset_add): Return void, for FONTSET_ADD.
5506 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5508 * alloc.c: Use bool for booleans.
5509 (gc_in_progress, abort_on_gc)
5510 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5511 (dont_register_blocks) [GC_MALLOC_CHECK]:
5512 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5513 (check_string_bytes, make_specified_string, memory_full)
5514 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5515 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5516 (mark_stack, valid_pointer_p, make_pure_string)
5517 (Fgarbage_collect, survives_gc_p, gc_sweep):
5518 Use bool for booleans, instead of int.
5519 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5520 Remove unused local.
5521 * alloc.c (PURE_POINTER_P):
5522 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5523 * editfns.c (Fformat):
5524 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5526 * fns.c (sweep_weak_table):
5527 * lisp.h (suppress_checking, push_message, survives_gc_p)
5528 (make_pure_string, gc_in_progress, abort_on_gc):
5529 * lread.c (readchar, read1):
5530 * print.c (Fprin1_to_string):
5531 * xdisp.c (push_message):
5532 Use bool for booleans affected directly or indirectly by
5535 Make recently-introduced setters macros.
5536 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5537 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5538 (set_fontset_default, set_fontset_fallback): Rename from their
5539 upper-case counterparts, and make them functions rather than macros.
5540 This is more consistent with the other recently-introduced setters.
5541 These don't need to be inline, since they're local.
5543 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5545 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5546 the loop (Bug#12247).
5548 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5550 * lisp.h (vcopy): Use memcpy rather than our own loop.
5551 This fixes a performance regression introduced by the recent
5552 addition of vcopy. This means 'vcopy' will need to be modified
5553 for a copying collector, but that's OK. Also, tighten the
5554 checking in the assertion.
5556 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5558 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5559 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5560 non-base glyph for the width of the base character, according to
5561 what x_draw_composite_glyph_string_foreground expects.
5562 Generate WADJUST value according to composition_gstring_width's
5563 expectations, to produce correct width of the composed character.
5564 Reverse the sign of the DU offset produced by ScriptPlace.
5566 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5568 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5570 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5572 Avoid direct writes to contents member of struct Lisp_Vector.
5573 * lisp.h (vcopy): New function to copy data into vector.
5574 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5575 * fns.c (Ffillarray): Use ASET.
5576 * keyboard.c (timer_check_2): Use AREF and ASET.
5577 (append_tool_bar_item, Frecent_keys): Use vcopy.
5578 * lread.c (read_vector): Use ASET.
5579 * msdos.c (Frecent_doskeys): Use vcopy.
5580 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5581 (Finternal_merge_in_global_face): Use ASET and vcopy.
5582 * xfont.c (xfont_list_pattern): Likewise.

5587 the position of its buffer's point.
5588 (Fset_window_point): For the selected window always go in its
5589 buffer to the specified position.
5591 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5593 Setter macros for fontsets.
5594 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5595 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5596 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5599 2012-08-20 Glenn Morris <rgm@gnu.org>
5601 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5602 Don't assume that `ln -f' works.
5604 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5606 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5607 and later about non-assignments with no effect. See discussion at
5608 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5611 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5613 Inline setter functions for Lisp_Objects slots of struct specbinding.
5614 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5617 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5619 * window.c (select_window): Always make selected window's buffer
5622 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5624 Use AREF and ASET for docstrings of category tables.
5625 * category.h (CATEGORY_DOCSTRING): Use AREF.
5626 (SET_CATEGORY_DOCSTRING): Use ASET.
5627 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5629 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5631 Inline setter functions for hash table members.
5632 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5633 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5634 (set_hash_key_and_value, set_hash_index, set_hash_next)
5635 (set_hash_hash): New functions.
5636 * charset.c, fns.c: Adjust users.
5638 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5640 Inline getter and setter functions for per-buffer values.
5641 * buffer.h (per_buffer_default, set_per_buffer_default)
5642 (per_buffer_value, set_per_buffer_value): New functions.
5643 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5644 * buffer.c, data.c: Adjust users.
5646 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5648 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5650 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5652 Rely on <config.h> + <unistd.h> to declare 'environ',
5653 as gnulib does this if the system doesn't.
5654 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5655 Remove declaration. MS-Windows declares it on stdlib.h which is
5656 included by conf_post.h.
5657 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5658 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5659 * vm-limit.c: Include <unistd.h>, for 'environ'.
5661 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5662 (start_of_data): Remove decl; mem-limits.h provides it.
5664 * xdisp.c (handle_invisible_prop): Make it a bit faster
5665 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5667 2012-08-19 Chong Yidong <cyd@gnu.org>
5669 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5672 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5674 * .gdbinit: Use call instead of set when calling a function in the
5677 * data.c (set_internal): Don't use set_blv_found.
5678 (Fkill_local_variable): Likewise.
5680 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5682 * nsfont.m (ns_ascii_average_width): Ensure the string
5683 ascii_printable is initialized with a null-terminated character
5684 array. Otherwise, it can contain undesired extra characters.
5686 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5688 port new setting code to Sun C 5.8 2005/10/13
5689 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5690 Return void, not Lisp_Object. Otherwise, the compiler
5691 complains about (A?B:C) where B is void and C is Lisp_Object
5692 when compiling CHAR_TABLE_SET, due to the recent change to
5693 the API of sub_char_table_set_contents.
5695 2012-08-18 Chong Yidong <cyd@gnu.org>
5697 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5698 for the string case (Bug#3874).

5853 The old version was confusing because it used the same name
5854 'parent' for two different things.
5856 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
5858 Functions to get and set Lisp_Object fields of buffer-local variables.

5867 font spec, make the font's attributes take precedence over
5868 directly-specified attributes.
5869 (merge_face_ref): Recognize :font.
5871 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

6525 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6526 * w32.c (init_environment): Change the default values of many
6527 environment variables in dflt_envvars[] to NULL, to avoid pushing
6528 them into environment when they were not already defined.
6529 Remove the code that deletes site-lisp subdirectories from the default
6530 value of EMACSLOADPATH, as it is no longer needed.
6531 (check_windows_init_file): Now external, not static.
6532 Use Vload_path as is, without adding anything, as this function is now
6533 called when Vload_path is already set up.
6535 * w32.h (check_windows_init_file): Add prototype.
6537 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6544 installation tree, as appropriate.
6546 * callproc.c (init_callproc_1): Call decode_env_path instead of
6547 doing its equivalent by hand.

6549 the code that sets Vexec_path run on MS-Windows.
6551 * lread.c (init_lread): Add comments to #ifdef's.
6553 * msdos.c (dos_set_window_size, IT_update_begin)

6565 Remove unnecessary casts involving pointers.
6566 These casts are no longer needed now that we assume C89 or later,

6580 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6581 Remove unnecessary pointer casts.
6582 * alloc.c (record_xmalloc): New function.
6583 * lisp.h (record_xmalloc): New decl.
6584 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6585 more like a function. This is because the pointer cast is not
6586 needed. All uses changed.
6587 * print.c (print_string, print_error_message): Avoid length recalc.
6589 Improve fix for macroexp crash with debugging (Bug#12118).
6590 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6591 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6592 not supposed to be invoked from the garbage collector.
6593 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6594 (gc_aset): New function, which is like ASET but can be
6595 used in the garbage collector.

6624 with addition of handling of symlinks and support for 'lstat'.
6625 If possible, get file's attributes and security information by
6626 handle, not by name. Produce S_IFLNK bit for symlinks, when
6627 called from 'lstat'.
6628 (stat, lstat): New functions, call 'stat_worker'.
6629 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6630 symlinks when the underlying filesystem supports them.
6632 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6634 Fix macroexp crash on Windows with debugging (Bug#12118).
6635 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6636 checking subscripts; problem introduced with the recent
6637 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6638 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6639 since it's used in non-static inline functions now.
6641 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6642 Don't assume buffer size fits in 'int'. Remove unused local.

6659 * category.c (CATEGORY_INLINE):
6660 * character.c (CHARACTER_INLINE):
6661 * charset.c (CHARSET_INLINE):
6662 * composite.c (COMPOSITE_INLINE):
6663 * dispnew.c (DISPEXTERN_INLINE):
6664 * sysdep.c (SYSTIME_INLINE):
6665 Define to EXTERN_INLINE, so that the corresponding functions
6666 are compiled into code.
6667 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6668 (INLINE_HEADER_END): New macros.
6669 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6689 hard-coding the path separator.
6691 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6693 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6694 This how ASET and AREF are supposed to work, and makes
6695 it easier to think about future improvements. See
6696 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6697 * charset.h (set_charset_attr): New function.

7189 the fix for 12036 would have avoided some of the problems noted in
7190 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7191 would have been more obvious.

7201 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7202 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7203 not be usable in #if. This simplifies things.
7205 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7207 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7212 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7213 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7214 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7215 Adjust to changes in lisp.h and emacs.c, by using

7218 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

7220 instead of gdb_valbits.
7221 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7222 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7223 instead of gdb_array_mark_flag.
7224 (xboolvector): Get size from $->size, not $->header.size.

8130 Avoid the need for strncpy, by using build_string or
8131 make_unibyte_string directly. Use dtoastr, not snprintf.
8132 * process.c (Fmake_network_process): Diagnose service names that
8133 are too long, rather than silently truncating them or creating
8134 non-null-terminated names.
8135 (Fnetwork_interface_info): Likewise, for interface names.
8136 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8137 Prefer sprintf to strncat.
8138 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

8150 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8151 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

8164 Optimize pure C strings initialization.
8165 * lisp.h (make_pure_string): Fix prototype.
8166 (build_pure_c_string): New function, defined as static inline. This
8167 provides a better opportunity to optimize away calls to strlen when
8168 the function is called with compile-time constant argument.
8169 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8170 argument, adjust users accordingly. Use build_pure_c_string where
8172 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8173 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8174 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8176 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8178 Avoid calls to strlen in miscellaneous functions.
8179 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8180 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8181 * lread.c (openp): Likewise.
8183 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8185 Avoid calls to strlen in path processing functions.
8186 * fileio.c (file_name_as_directory): Add comment. Change to add
8187 srclen argument and return the length of result. Adjust users
8189 (directory_file_name): Fix comment. Change to add srclen argument,
8190 swap 1st and 2nd arguments to obey the common convention.
8191 Adjust users accordingly.
8192 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8194 2012-07-10 Glenn Morris <rgm@gnu.org>
8196 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

8201 * s/gnu.h (DATA_START): Move definitions to configure.
8203 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8204 We include usg5-4-common.h, which defines them both.
8206 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8207 O_RDONLY already includes it).
8209 Stop ns builds setting the EMACSLOADPATH environment variable.
8210 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8211 Now it does not set EMACSLOADPATH, just returns the load-path string.
8212 * nsterm.h: Update accordingly.
8213 * lread.c [HAVE_NS]: Include nsterm.h.
8214 (init_lread) [HAVE_NS]: Use ns_load_path.

8217 2012-07-09 Glenn Morris <rgm@gnu.org>
8219 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8220 since the included bsd-common.h does so.
8222 Stop ns builds setting the EMACSPATH environment variable.
8223 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8224 (ns_init_paths): Do not set EMACSPATH.
8225 * nsterm.h (ns_exec_path): Add it.
8226 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8229 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8231 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8233 * process.c (wait_reading_process_output): 'waitchannels' was unset
8234 when read_kbd || !NILP (wait_for_cell); fix this.
8236 Add GCC-style 'const' attribute to functions that can use it.
8237 * character.h (char_resolve_modifier_mask):
8238 * keyboard.h (make_ctrl_char):
8239 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8246 Declare the dummy function with ATTRIBUTE_CONST.
8247 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8248 Add decls with ATTRIBUTE_CONST.
8250 Minor improvements to make_formatted_string.
8251 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8252 where int is good enough, as vsprintf returns an int.
8253 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8255 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8257 Use make_formatted_string to avoid double length calculation.
8258 * lisp.h (make_formatted_string): New prototype.
8259 * alloc.c (make_formatted_string): New function.
8260 * buffer.c (Fgenerate_new_buffer_name): Use it.

8265 (x_report_frame_params): Likewise.
8266 * image.c (gs_load): Likewise.
8267 * minibuf.c (get_minibuffer): Likewise.

8282 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8284 Move marker debugging code under MARKER_DEBUG.
8285 * marker.c (MARKER_DEBUG): Move marker debugging code under
8286 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8287 for bootstrap with --enable-checking (~3x slowdown reported
8288 by Juanma Barranquero <lekktu@gmail.com>).
8289 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8291 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8293 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8294 See <http://bugs.gnu.org/11825#29>.
8296 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8298 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8299 has no font, use the frame's font. (Bug#11813)
8300 (display_line): Add commentary about displaying truncation glyphs
8302 (produce_special_glyphs): Move here from term.c.
8304 * term.c (produce_special_glyphs): Move to xdisp.c.
8306 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8309 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8311 * xdisp.c (display_line): Avoid warning about implicit declaration
8314 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8316 * lisp.h: Remove empty conditional.
8318 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8320 * lread.c (load_path_check): Now static.
8322 Fix some minor --with-ns problems found by static checking.
8323 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8324 (x_set_font) [!HAVE_X_WINDOWS]:
8325 * image.c (xpm_load_image) [HAVE_NS]:
8326 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8327 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8328 Remove unused local.
8329 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8330 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8331 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8332 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8333 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8334 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8335 Fix pointer signedness problem.
8336 * xfaces.c (FRAME_X_FONT_TABLE):
8337 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8339 2012-07-07 Glenn Morris <rgm@gnu.org>
8341 * lread.c (load_path_check): New function, split from init_lread.
8342 (init_lread): Reorganize. Motivation:
8343 If EMACSLOADPATH is set, check/warn about that rather than the
8344 defaults, which we are not going to use. Hence we can remove
8345 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8346 Don't warn if site-lisp directories are missing.
8347 If not installed, start from a blank load-path, since
8348 PATH_LOADSEARCH refers to the eventual installation directories.
8350 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8352 Support truncation and continuation glyphs on GUI frames, when
8353 fringes are disabled. (Bug#11832)
8354 * xdisp.c (init_iterator): Get dimensions of truncation and
8355 continuation glyphs even if on GUI frames.
8356 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8357 or both, are absent.
8358 (start_display, move_it_in_display_line_to): Handle the case of a
8359 GUI frame without a fringe to display continuation or truncation
8361 (insert_left_trunc_glyphs): Support GUI frames: make sure
8362 truncation glyphs overwrite enough glyphs from the current line to
8363 have sufficient space in pixels.
8364 (display_line): Support truncation and continuation glyphs on GUI
8365 frames. If some spare pixels are left on the line after inserting
8366 the truncation glyphs, fill that space with a stretch glyph of a
8367 suitably computed width.
8369 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8370 produce_glyphs, to support GUI sessions.
8372 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8374 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8376 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8378 Do not require float-time's arg to fit in time_t (Bug#11825).
8379 This works better on hosts where time_t is unsigned, and where
8380 float-time is applied to the (negative) difference between two times.
8381 * editfns.c (decode_time_components): Last arg is now double *,
8382 not int *, and means to store all the result as a double, without
8383 worrying about whether the seconds part fits in time_t.
8384 All callers changed.
8385 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8386 All callers changed.
8387 (Ffloat_time): Do not fail merely because the specified time falls
8388 outside of time_t range.
8390 2012-07-07 Glenn Morris <rgm@gnu.org>
8392 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8398 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8399 Update dependencies.
8401 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8403 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8405 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

8407 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8408 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8409 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

8412 * xfont.c (compare_font_names): Redo to omit the need for casts.
8414 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8416 * xfns.c (Fx_change_window_property): Doc fix.
8417 * w32fns.c (Fx_change_window_property): Doc fix.
8419 * w32fns.c (Fx_window_property): Accept the same arguments as the
8420 X Windows version. Doc fix.
8421 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8423 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8424 Eli Zaretskii <eliz@gnu.org>
8426 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8427 Windows-specific code from nt/config.nt moved here.
8428 Obsolete settings removed.
8430 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8432 * process.c: Avoid unnecessary calls to gettime.
8433 (wait_reading_process_output): Don't get the time of day
8434 when gobbling data immediately and not waiting, as there's no need
8435 for it in that case. This removes a FIXME.
8437 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8439 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8440 is defined (Bug#11768).
8442 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8444 Fix marker debugging code.
8445 * marker.c (byte_char_debug_check): Do not perform the check
8446 if buffer is not multibyte.
8447 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8448 Call byte_char_debug_check with correct arguments.
8450 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8452 Compile marker debugging code only if ENABLE_CHECKING is defined.
8453 * marker.c (byte_char_debug_check, count_markers):
8454 Use only if ENABLE_CHECKING is defined.
8455 (byte_debug_flag): Remove.
8456 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8457 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8459 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8461 Avoid code repetition in marker-related functions.
8462 * marker.c (attach_marker): New function.
8463 (Fset_marker, set_marker_restricted, set_marker_both)
8464 (set_marker_restricted_both): Use it.
8465 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8466 Consistently rename charno to charpos.
8467 (marker_position): Add eassert.
8468 (marker_byte_position): Convert to eassert.

8487 * window.c (save_window_save): Likewise.
8489 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8491 Do not use Fdelete_overlay in delete_all_overlays
8492 to avoid redundant calls to unchain_overlay.
8493 * buffer.c (drop_overlay): New function.
8494 (delete_all_overlays, Fdelete_overlay): Use it.
8495 * minibuf.c (get_minibuffer): Fix comment.
8497 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8499 Port to OpenBSD 5.1 amd64.
8500 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8501 This is needed for OpenBSD, and should be harmless on all BSD systems.
8502 Also, include <sys/sysctl.h>, as it should be available on all
8503 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8504 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8505 use p_pid member, not kp_proc.pid.
8507 2012-07-06 Glenn Morris <rgm@gnu.org>
8509 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8511 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8513 More xmalloc and related cleanup.
8514 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8515 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

8522 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8524 Omit needless casts involving void * pointers and allocation.
8525 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8526 as the former is more robust if P's type is changed.
8527 Prefer xzalloc to xmalloc + memset 0.
8528 Simplify malloc-or-realloc to realloc.
8529 Don't worry about xmalloc returning a null pointer.
8530 Prefer xstrdup to xmalloc + strcpy.
8531 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8533 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8534 alloca of a constant.
8536 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8538 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8539 hscroll is larger than the line width. Fixes long and futile
8540 looping inside extend_face_to_end_of_line (on a TTY) producing
8541 glyphs that are not needed and thrown away.
8543 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8545 * marker.c (set_marker_restricted_both): Simplify by using
8548 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

8571 * xdisp.c (window_hscroll_limited): New function.
8572 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8573 coordinates when window's hscroll is set to insanely large
8576 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8578 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8579 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
8581 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8584 * lisp.h (xzalloc): New prototype. Omit needless casts.
8585 * alloc.c (xzalloc): New function. Omit needless casts.

8639 * fileio.c (time_error_value): Check the right error number.
8640 Problem reported by Troels Nielsen in
8641 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8643 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8645 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8646 This should be fixed in a better way; see Eli Zaretskii in
8647 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8648 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8650 * fileio.c (time_error_value): Rename from special_mtime.
8651 The old name's problems were noted by Eli Zaretskii in
8652 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8654 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8655 This variable's comment says Emacs needs at least one GDB-visible
8656 symbol of type enum pvec_type, to work around GDB problems.
8657 The symbol's value doesn't matter.
8659 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8660 that causes compilation to fail on pre-C99 compilers.
8662 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8664 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8665 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8667 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8669 * buffer.c (init_buffer_once): Fix initialization of
8670 headers for buffer_defaults and buffer_local_symbols.
8671 Reported by Juanma Barranquero <lekktu@gmail.com>.
8673 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8675 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8676 * lisp.h (enum pvec_type): Use fewer bits.
8677 (PSEUDOVECTOR_SIZE_BITS): New constant.
8678 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8679 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8680 change in pvec_type.
8681 (PSEUDOVECTOR_TYPEP): New macro.
8682 (TYPED_PSEUDOVECTORP): Use it.
8683 * fns.c (internal_equal): Adapt code to extract pvectype.
8684 * emacs.c (gdb_pvec_type): Update type.
8685 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8686 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8687 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8688 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8689 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8690 abusing vector->header.next.nbytes.
8691 (live_vector_p): Use PVEC_TYPE.
8692 (mark_object): Adapt code to extract pvectype. Use switch.
8694 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8696 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8697 Tighten new eassert a bit.
8699 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8701 Fix compilation with --enable-gcc-warnings and -O1
8703 * doprnt.c (doprnt): Change type of tem to int, initialize
8704 to avoid compiler warning. Add eassert.
8705 * search.c (simple_search): Initialize match_byte to avoid
8706 compiler warning. Add eassert.
8708 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8710 Avoid weird behavior with large horizontal scrolls.
8711 Without this change, for example, large hscroll values would
8712 mess up Emacs's display on Fedora 15 x86, presumably due to
8713 overflows in int calculations in the display code.
8714 Also, if buffers had long lines, Emacs would freeze.
8715 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8716 (set_window_hscroll): New function, containing the old guts of
8717 Fset_window_hscroll. Return the clipped value.
8718 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8719 This avoids the need to check against PTRDIFF_MAX.
8721 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8723 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8725 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8727 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8729 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8730 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8731 since GCC 4.4.6 issues a bogus warning for them.
8733 Fix bugs in file timestamp newness comparisons.
8734 * fileio.c (Ffile_newer_than_file_p):
8735 * lread.c (Fload): Use full timestamp resolution of files,
8736 not just the 1-second resolution, so that files that are only
8737 slightly newer still count as newer.
8738 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8739 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8741 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8743 * fileio.c: Improve handling of file time marker. (Bug#11852)
8744 (special_mtime): New function.
8745 (Finsert_file_contents, Fverify_visited_file_modtime):
8746 Use it to set special mtime values consistently.
8748 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8750 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8751 marker for non-existing file. (Bug#11852)
8753 2012-07-03 Glenn Morris <rgm@gnu.org>
8755 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8756 and did not make it into globals.h).
8758 2012-07-03 Tom Tromey <tromey@redhat.com>
8760 * window.c (Fset_window_margins, Fset_window_fringes)
8761 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8762 * textprop.c (Fprevious_property_change): No longer static.
8763 * syntax.c (Fsyntax_table_p): No longer static.

8784 * dispextern.h: Remove EXFUNs.
8785 * intervals.h: Remove EXFUNs.
8786 * fontset.h: Remove EXFUN.

8791 * w32term.h: Remove EXFUNs.
8792 * window.h: Remove EXFUNs.
8793 * xsettings.h: Remove EXFUN.
8794 * xterm.h: Remove EXFUN.
8796 2012-07-03 Glenn Morris <rgm@gnu.org>
8798 * lisp.h (Frandom): Make it visible to C.
8799 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8800 buffer for invisible buffers. (Bug#1229)
8802 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8804 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8805 values which aren't power of 2.
8806 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8807 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8810 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8812 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8814 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8816 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8818 * alloc.c (allocate_vector_block): Remove redundant
8819 calls to mallopt if DOUG_LEA_MALLOC is defined.
8820 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8821 avoid calls to mallopt if zero_vector is returned.
8823 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8825 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8826 is enabled, avoid dereferencing NULL current_sblock if
8829 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8831 Cleanup basic buffer management.
8832 * buffer.h (struct buffer): Change layout to use generic vector
8833 marking code. Fix some comments. Change type of 'clip_changed'
8834 to bitfield. Remove unused #ifndef old.
8835 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8836 (GET_OVERLAYS_AT): Fix indentation.
8837 (for_each_per_buffer_object_at): New macro.

8841 * alloc.c (allocate_buffer): Adjust to match new layout of
8842 struct buffer. Fix comment.
8843 (mark_overlay): New function.

8846 (mark_object): Use it. Adjust marking of misc objects
8847 and related comments.
8849 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8851 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8852 wrapper that is not needed because the wrapped code is a no-op (zero
8853 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8854 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8856 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8858 * alloc.c (mark_buffer): Simplify. Remove prototype.
8859 (mark_object): Add comment. Reorganize marking of vector-like
8860 objects. Use CHECK_LIVE for all vector-like objects except buffers
8861 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8862 Avoid redundant calls to mark_vectorlike for bool vectors.
8864 2012-06-30 Glenn Morris <rgm@gnu.org>
8866 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8868 * epaths.in (PATH_SITELOADSEARCH): New.
8869 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8870 This is rather than relying on --enable-locallisppath elements
8871 having "site-lisp" in their names. (Bug#10208#25, 11658)
8873 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8875 * w32proc.c (sys_select): Accept and ignore one more argument.
8877 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8879 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8880 (pselect) [!MS_DOS]: Redirect to sys_select.
8882 * sysdep.c: Don't include dos.h and dosfns.h.
8884 * process.c (sys_select):
8885 * msdos.c (sys_select): Accept one more argument and ignore it.
8887 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8888 adapt data types and code to that.
8891 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8892 which clashes with the gnulib function of the same name.
8894 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8896 * font.c (font_style_to_value, font_style_symbolic)
8897 (font_prop_validate_style): Add type checks for values in
8900 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8902 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8905 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8907 * xdisp.c (try_window_id): Undo last change.
8909 * w32.c (getwd): Adjust commentary about startup_dir.
8910 (init_environment): Always call sys_access, even in non-MSVC
8911 builds. Don't chdir to the directory of the Emacs executable.
8912 This undoes code from 1997 which was justified by the need to
8913 "avoid conflicts when removing and renaming directories". But its
8914 downside was that every relative file name was being interpreted
8915 relative to the directory of the Emacs executable, which can never
8916 be TRT. In particular, it broke sys_access when called with
8917 relative file names.
8918 (sys_access): Map GetLastError to errno.
8920 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8922 * window.h (struct window): Change type of 'fringes_outside_margins'

8926 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8929 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8931 * gnutls.c (emacs_gnutls_handshake):
8932 Add QUIT to make the loop interruptible.
8934 2012-06-29 Glenn Morris <rgm@gnu.org>
8936 * charset.c (init_charset): Make lack of etc/charsets fatal.
8938 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8940 * editfns.c (region_limit): Fix type mismatch.
8942 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8944 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8945 undefined. Convert from xassert to eassert.
8946 * nsmenu.m: Convert from xassert to eassert.
8947 * nsterm.m: Likewise.
8949 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8951 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8953 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8955 Avoid integer overflow on scroll-left and scroll-right.
8956 * window.c (HSCROLL_MAX): New macro.
8957 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8958 overflow when requested scroll falls outside ptrdiff_t range.
8960 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8962 * window.h (struct window): Change type of 'hscroll',
8963 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8964 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8965 Adjust users accordingly.
8966 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8967 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8968 from EMACS_INT to ptrdiff_t.
8969 (make_window): Omit redundant initialization.
8971 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8973 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8975 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8977 * window.h (struct window): Change type of 'use_time' and
8978 'sequence_number' from Lisp_Object to int.

8987 enabled with --enable-checking=[all,glyphs] configure option.
8988 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8989 adjust comments accordingly.

9040 avoid GCC warning about unused macro.
9042 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9044 * alloc.c (allocate_string): Omit intervals initialization.
9045 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9046 as in make_pure_string and make_pure_c_string.
9048 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9050 * alloc.c (allocate_string): Fix last change.
9052 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9102 * alloc.c: Remove build_string.
9103 * lisp.h: Define build_string as static inline. This provides
9104 a better opportunity to optimize away calls to strlen when the
9105 function is called with compile-time constant argument.
9106 * image.c (imagemagick_error): Convert to build_string.
9107 * w32proc.c (sys_spawnve): Likewise.
9108 * xterm.c (x_term_init): Likewise.
9110 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9112 Use sprintf return value instead of invoking strlen on result.
9113 In the old days this wasn't portable, since some sprintf
9114 implementations returned char *. But they died out years ago and
9115 Emacs already assumes sprintf returns int.
9116 Similarly for float_to_string.
9117 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9118 * ccl.c (ccl_driver):
9119 * character.c (string_escape_byte8):
9120 * data.c (Fnumber_to_string):

9122 * print.c (print_object):
9123 * xdisp.c (message_dolog):
9124 * xfns.c (syms_of_xfns):
9125 Use sprintf or float_to_string result to avoid need to call strlen.
9126 * data.c (Fnumber_to_string):
9127 Use make_unibyte_string, since the string must be ASCII.
9128 * lisp.h, print.c (float_to_string): Now returns int length.
9129 * term.c (produce_glyphless_glyph):
9130 Use sprintf result rather than recomputing it.
9132 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9133 * Makefile.in (ALL_CFLAGS):
9134 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9135 * gmalloc.c, regex.c: Include <config.h> unconditionally.
9137 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9139 * dispextern.h (xstrcasecmp): Define to library function
9140 strcasecmp if available.
9141 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
9143 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

9156 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9158 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9159 sprintf already null-terminates its output.
9161 * xfns.c (x_window): Remove redundant cast.
9163 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9165 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9166 `const char *' to `char *' to avoid compiler warning.
9168 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9170 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9171 instead of truncating it to 63 (admittedly a generous limit).
9173 * process.c: Fix spelling and caps in comments.
9175 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9177 * emacs.c (setpgrp): Remove definition, unused.

9221 Use _Noreturn rather than NO_RETURN.
9222 No need for separate decl merely because of _Noreturn.
9223 * sound.c (sound_warning, parse_sound):
9224 Remove unnecessary forward decls.
9226 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9228 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
9229 * lisp.h (WAIT_READING_MAX): New macro.
9230 * dispnew.c (Fsleep_for, sit_for):
9231 * keyboard.c (kbd_buffer_get_event):
9232 * process.c (Faccept_process_output):
9233 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9234 This improves on the previous patch, which introduced a bug
9235 when time_t is unsigned and as wide as intmax_t.
9236 See <http://bugs.gnu.org/9000#51>.
9238 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9240 * dispnew.c (sit_for, Fsleep_for):
9241 * keyboard.c (kbd_buffer_get_event):

9254 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9255 Privately reported by Herbert J. Skuhra.
9256 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9258 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9259 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9261 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9263 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9264 last argument of make_unibyte_string.
9266 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9267 language ID in the event parameters.
9269 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9270 event.code, not the obscure "character set ID".
9272 2012-06-23 Chong Yidong <cyd@gnu.org>
9274 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9276 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9278 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

9293 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9294 Privately reported by Herbert J. Skuhra.
9295 [__FreeBSD__]: Remove "*/" typo after "#include".

9299 Don't assume EMACS_TIME and struct timeval are the same type.
9301 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9303 Support higher-resolution time stamps (Bug#9000).
9304 The time stamps are only nanosecond-resolution at the C level,
9305 since that's the best that any real-world system supports now.
9306 But they are picosecond-resolution at the Lisp level, as that's
9307 easy, and leaves room for future OS improvements.
9309 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9312 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9313 Don't get current time unless it's needed.
9315 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9316 now provides it if it's absent.
9317 (start_atimer): Port to higher-res time stamps.
9318 Check for time stamp overflow. Don't get current time more
9319 often than is needed.
9321 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9322 Include systime.h, not time.h.
9323 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9325 * dired.c: Include stat-time.h.
9326 (Ffile-attributes): File times now have higher resolution.
9328 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9329 (struct image): Timestamp now has higher resolution.
9331 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9332 has at least microseconds now. All uses removed.
9333 (update_frame, update_single_window, update_window, update_frame_1)
9334 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9335 (duration_to_sec_usec): Remove; no longer needed.
9337 * editfns.c (time_overflow): Now extern.
9338 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9339 (float-time, Fformat_time_string, Fcurrent_time_string)
9340 (Fcurrent_time_zone): Accept and generate higher-resolution
9342 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9343 (decode_time_components, lisp_seconds_argument): New functions.
9344 (make_time): Now static.
9345 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9346 Report an error if the time is invalid, rather than having the caller
9349 * fileio.c: Include <stat-time.h>
9350 (Fcopy_file): Copy higher-resolution time stamps.
9351 Prefer to set the time stamp via a file descriptor if that works.
9352 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9353 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9354 (Fvisited_file_modtime, Fset_visited_file_modtime):
9355 Support higher-resolution time stamps.
9357 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9359 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9361 * image.c (prepare_image_for_display, clear_image_cache)
9362 (lookup_image): Port to higer-resolution time stamps.
9364 * keyboard.c (start_polling, bind_polling_period):
9365 Check for time stamp overflow.
9366 (read_char, kbd_buffer_get_event, timer_start_idle)
9367 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9368 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9369 Port to higher-resolution time stamps. Do not assume time_t is signed.
9370 (decode_timer): New function. Timers are now vectors of length 9,
9371 not 8, to accommodate the picosecond component.
9372 (timer_check_2): Use it.
9374 * nsterm.m (select_timeout, timeval_subtract): Remove.
9375 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9376 as they're a bit more accurate and handle overflow better.
9377 (ns_select): Change prototype to be compatible with pselect.
9378 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9379 * nsterm.h (ns_select): Adjust prototype.
9381 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9382 us-resolution time stamps.
9383 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9385 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9387 * lisp.h (time_overflow): New decl.
9388 (wait_reading_process_output): First arg is now intmax_t, not int,
9389 to accommodate larger waits.
9391 * process.h (struct Lisp_Process.read_output_delay):
9392 Now counts nanoseconds, not microseconds.
9393 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9395 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9396 (wait_reading_process_output):
9397 Port to ns-resolution time stamps.
9398 (Faccept_process_output, wait_reading_process_output):
9399 Check for time stamp overflow. Do not assume time_t is signed.
9400 (select_wrapper): Remove; we now use pselect.
9401 (Fprocess_attributes): Now generates ns-resolution time stamps.
9403 * sysdep.c: Include utimens.h. Don't include utime.h
9404 or worry about struct utimbuf; gnulib does that for us now.
9405 (gettimeofday): Remove; gnulib provides a substitute.
9406 (make_timeval): New function.
9407 (set_file_times): Now sets ns-resolution time stamps.
9408 New arg FD; all uses changed.
9409 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9410 (system_process_attributes):
9411 Now returns ns-resolution time stamp. All uses changed.
9412 Check for time stamp overflow.
9414 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9415 provides a substitute now.
9417 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9418 since it guarantees struct timespec.
9419 (EMACS_TIME): Now struct timespec, so that we can support
9420 ns-resolution time stamps.
9421 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9422 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9423 (EMACS_USECS): Remove.
9424 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9425 so multiply the arg by 1000 before storing it.
9426 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9428 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9429 Port to ns-resolution time stamps.
9430 (EMACS_TIME_NEG_P): Remove; replaced by....
9431 (EMACS_TIME_SIGN): New macro.
9432 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9433 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9434 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9435 (make_timeval, make_lisp_time, decode_time_components): New decls.
9436 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9437 that it mishandled time_t overflow. You can't compare by subtracting!
9438 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9439 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9441 * term.c: Include <sys/time.h>.
9442 (timeval_to_Time): New function, for proper overflow wraparound.

9445 * undo.c (record_first_change): Support higher-resolution time stamps
9447 (Fprimitive_undo): Use them when restoring time stamps.
9449 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9450 (w32_get_internal_run_time):
9451 Port to higher-resolution Emacs time stamps.
9452 (ltime): Now accepts single 64-bit integer, as that's more convenient
9455 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9457 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9458 for compatibility with pselect. Support ns-resolution time stamps.
9460 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9462 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9463 Check for time stamp overflow, and support ns-resolution time stamps.
9465 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9466 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9467 (timeval_subtract): Remove; no longer needed.
9468 (XTflash, XTring_bell, x_wait_for_event):
9469 Port to ns-resolution time stamps. Don't assume time_t is signed.
9471 2012-06-22 Chong Yidong <cyd@gnu.org>
9473 * xdisp.c (x_consider_frame_title): Revert last change.
9475 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9477 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9478 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9479 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9480 staticidx goes up to 1597 out of 1600 = 0x640.)
9482 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9484 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9485 Otherwise, the umask might be mistakenly 0 while handling input signals.
9487 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9489 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9494 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
9495 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9496 access to `contents' member of Lisp_Vector objects with AREF and ASET
9499 2012-06-19 Chong Yidong <cyd@gnu.org>
9501 * frame.c (delete_frame): When selecting a frame on a different
9502 text terminal, do not alter the terminal's top-frame.

9505 frame's selected window and its terminal's top-frame.
9506 (unwind_format_mode_line): Restore them.
9507 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9509 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9510 since tty frames can be explicitly named.
9511 (prepare_menu_bars): Likewise.
9513 * term.c (Ftty_top_frame): New function.
9515 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9517 Port byte-code-meter to modern targets.
9518 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9519 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9520 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9521 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9522 (METER_1, METER_2): Simplify.
9524 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
9526 * data.c (Fdefalias): Return `symbol' (bug#11686).
9528 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9530 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9531 gets killed during executing of this function (Bug#11665).
9532 Try to always return Qt when the buffer has been actually killed.
9533 (Vkill_buffer_query_functions): In doc-string say that functions
9534 run by this hook should not change the current buffer.
9536 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9538 Fix recently-introduced process.c problems found by static checking.
9539 * process.c (write_queue_push, write_queue_pop, send_process):

9754 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9755 Use an inline function on all platforms when using the union type,
9756 since this is simpler and 'static inline' can be used portably

9900 * doprnt.c (doprnt): Truncate multibyte char correctly.
9901 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9902 would mishandle a string argument "Xc" if X was a multibyte

9987 and 'double' in a couple of places.
9989 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9991 * xdisp.c (handle_stop): Detect whether we have overlay strings
9992 loaded by testing it->current.overlay_string_index to be
9993 non-negative, instead of checking whether n_overlay_strings is
9994 positive. (Bug#11587)

10011 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10012 for the duration of call to load_charset, to avoid problems with
10013 callers of maybe_unify_char that access buffer text through C
10016 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10017 decrement the inhibition flag, instead of just setting or

10024 This #undef was "temporary" in 2000; it is no longer needed
10025 now that '#define static' has gone away.
10026 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10027 (gray_bitmap_bits): Remove; no longer needed.
10028 All uses replaced with definiens.
10029 * xterm.c: Include "bitmaps/gray.xbm".
10031 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10033 Clean up __executable_start, monstartup when --enable-profiling.
10034 The following changes affect the code only when profiling.
10035 * dispnew.c (__executable_start): Rename from safe_bcopy.
10036 Define only on platforms that need it.
10037 * emacs.c: Include <sys/gmon.h> when profiling.
10038 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10039 (__executable_start): Remove decl, since lisp.h does it now.
10040 (safe_bcopy): Remove decl; no longer has that name.
10041 (main): Coalesce #if into single bit of code, for simplicity.
10042 Cast pointers to uintptr_t, since standard libraries want integers
10044 * lisp.h (__executable_start): New decl.
10046 2012-05-31 Glenn Morris <rgm@gnu.org>
10048 * image.c (Fimagemagick_types): Doc fix.
10050 2012-05-30 Jim Meyering <meyering@redhat.com>
10052 * callproc.c (Fcall_process_region): Include directory component

10055 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10057 * alloc.c, lisp.h (make_pure_vector): Now static.
10059 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10061 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10062 Move to byte-run.el.

10065 (Qdefun): Move from eval.c.
10066 * lisp.h (Qdefun): Remove.
10067 * lread.c (read1): Tiny simplification.
10069 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10071 Do not create empty overlays with the evaporate property (Bug#9642).
10072 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10073 Bug#9642, but explicitly check that the buffer the overlay would
10074 be moved to is live and rearrange lines to make sure that errors
10075 will not put the overlay in an inconsistent state.
10076 (Fdelete_overlay): Cosmetics.
10078 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10080 * w32term.c (my_bring_window_to_top): New function.
10081 (x_raise_frame): Use handle returned by DeferWindowPos, which
10082 could be different from the original one.

10092 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10094 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10095 This avoids undefined behavior that might cause the eassert
10096 to not catch an out-of-range value.
10098 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10100 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10101 Update dependencies.
10103 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10105 * bidi.c (bidi_mirror_char): Fix last change.
10107 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

10110 when referring to sectname field in printf format.
10112 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10114 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10115 Only r_alloc_inhibit_buffer_relocation needed to be added;
10116 the others were already declared.
10118 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10119 before checking whether it's out of range. Put the check inside
10121 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10123 2012-05-27 Ken Brown <kbrown@cornell.edu>
10125 * callproc.c (Fcall_process): Restore a line that was accidentally
10126 commented out in the 2011-02-13 change (bug#11547).
10128 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10130 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10131 defined on ralloc.c.
10133 * buffer.c [REL_ALLOC]: Remove prototypes of
10134 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10135 they are now on lisp.h.
10137 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10139 * search.c (search_buffer): Use it to inhibit relocation of buffer
10140 text while re_search_2 is doing its job, because re_search_2 is
10141 passed C pointers to buffer text. (Bug#11519)
10143 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10144 Update value to 24.
10146 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10147 state after an additional call to move_it_in_display_line_to, keep
10148 the values of it->max_ascent and it->max_descent found for the
10150 (pos_visible_p): Revert the comparison against bottom_y to what it
10151 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10154 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10156 Fix coding-related core dumps with gcc -ftrapv.
10157 The code was computing A - B, where A and B are pointers, and B is
10158 random garbage. This can lead to core dumps on platforms that
10159 have special pointer registers, and it also leads to core dumps on
10160 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10161 A - B only when B is initialized properly.
10162 * coding.c (coding_set_source, coding_set_destination): Return void.
10163 (coding_change_source, coding_change_destinations): New functions,
10164 with the old behaviors of coding_set_source and coding_set_destination.
10165 All callers that need an offset changed to use these new functions.
10167 2012-05-26 Glenn Morris <rgm@gnu.org>
10169 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10171 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10173 Extend mouse support on W32 text-mode console.
10174 * xdisp.c (draw_row_with_mouse_face):
10175 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10177 * w32console.c: Include window.h.
10178 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10180 (initialize_w32_display): Initialize mouse-highlight data.
10182 * w32inevt.c: Include termchar.h and window.h.
10183 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10184 moves, call note_mouse_highlight. If help_echo changed, call
10185 gen_help_event to produce help-echo message in the echo area.
10186 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10189 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10191 * lread.c (read1): Simplify slightly to avoid an overflow warning
10192 with GCC 4.7.0 on x86-64.
10194 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10196 * bidi.c (bidi_mirror_char): Revert last change: an int is
10197 definitely wide enough here.
10199 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10201 Fix integer width and related bugs (Bug#9874).
10202 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
10203 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
10204 (string_bytes, check_sblock, allocate_string_data):
10205 (compact_small_strings, Fmake_bool_vector, make_string)
10206 (make_unibyte_string, make_multibyte_string)
10207 (make_string_from_bytes, make_specified_string)
10208 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10209 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10211 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10212 (allocate_pseudovector):
10213 Use int, not EMACS_INT, where int is wide enough.
10214 (inhibit_garbage_collection, Fgarbage_collect):
10215 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10216 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10217 int might not be wide enough.
10218 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10219 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10220 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10221 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10222 (bidi_level_of_next_char, bidi_move_to_visually_next):
10223 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10224 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10225 (Fkill_buffer, Fset_buffer_major_mode)
10226 (advance_to_char_boundary, Fbuffer_swap_text)
10227 (Fset_buffer_multibyte, overlays_at, overlays_in)
10228 (overlay_touches_p, struct sortvec, record_overlay_string)
10229 (overlay_strings, recenter_overlay_lists)
10230 (adjust_overlays_for_insert, adjust_overlays_for_delete)
10231 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
10232 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
10233 (Foverlay_recenter, last_overlay_modification_hooks_used)
10234 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10235 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10236 (validate_region): Omit unnecessary test for b <= e,
10237 since that's guaranteed by the previous test.
10238 (adjust_overlays_for_delete): Avoid pos + length overflow.
10239 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10240 (report_overlay_modification):
10241 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10242 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10243 Omit pointer cast, which isn't needed anyway, and doesn't work
10244 after the EMACS_INT -> ptrdiff_t change.
10245 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10246 * buffer.h: Adjust decls to match defn changes elsewhere.
10247 (struct buffer_text, struct buffer):
10248 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10249 Use EMACS_INT, not int, where int might not be wide enough.
10250 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10251 not int, to avoid needless 32-bit limit on 64-bit hosts.
10252 (exec_byte_code): Use tighter memory-full test, one that checks
10253 for alloca overflow. Don't compute the address of the object just
10254 before an array, as that's not portable. Use EMACS_INT, not
10255 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10256 * callint.c (Fcall_interactively):
10257 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10258 * callproc.c (call_process_kill, Fcall_process):
10259 Don't assume pid_t fits into an Emacs fixnum.
10260 (call_process_cleanup, Fcall_process, child_setup):

10264 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10265 (Fcall_process): Simplify handling of volatile integers.

10267 * casefiddle.c (casify_object, casify_region, operate_on_word)
10268 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10270 (casify_object): Avoid integer overflow when overallocating buffer.
10271 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10272 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10273 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10274 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10275 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10276 integers are now checked earlier. All uses replaced with XINT.
10278 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10279 For CCL_MapSingle, check that content and value are in int range.
10280 (ccl_driver, Fregister_code_conversion_map):
10281 Check that Vcode_version_map_vector is a vector.
10282 (resolve_symbol_ccl_program): Check that vector header is in range.
10283 Always copy the vector, so that we can check its contents reliably
10284 now rather than having to recheck each instruction as it's being
10285 executed. Check that vector words fit in 'int'.
10286 (ccl_get_compiled_code, Fregister_ccl_program)
10287 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10288 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10289 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10290 contents are in range.
10291 (Fccl_execute_on_string): Check that status is in range.
10292 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10293 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10294 Accept and return EMACS_INT, not int, because callers can pass values
10295 out of 'int' range.
10296 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10297 (multibyte_chars_in_text, parse_str_as_multibyte)

10299 (str_as_unibyte, str_to_unibyte, string_count_byte8)
10300 (string_escape_byte8, Fget_byte):
10301 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10302 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10303 avoid mishandling large integers.
10304 * character.h: Adjust decls to match defn changes elsewhere.
10305 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10306 (Ffind_charset_region):
10307 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

10309 (load_charset_map_from_vector, Fdefine_charset_internal):
10310 Don't assume fixnum fits in int.
10311 (load_charset_map_from_vector, Fmap_charset_chars):
10312 Remove now-unnecessary CHECK_NATNUMs.
10313 (Fdefine_charset_internal): Check ranges here, more carefully.
10314 Don't rely on undefined behavior with signed left shift overflow.
10315 Don't assume unsigned int fits into fixnum, or that fixnum fits
10316 into unsigned int. Don't require max_code to be a valid fixnum;
10317 that's not true for gb10830 4-byte on a 32-bit host. Allow
10318 invalid_code to be a cons, for the same reason. Require code_offset
10319 to be a character. Avoid int overflow if max_char is close
10321 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10322 this is intended anyway and avoids some undefined behavior.
10323 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10324 INDEX_TO_CODE_POINT, as that's what it expects.
10325 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10326 * charset.h (DECODE_CHAR): Return int, not unsigned;
10327 this is what was intended anyway, and it avoids undefined behavior.
10328 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10329 integer-overflow issues.
10330 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10331 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10332 where the argument is EMACS_INT, and this behavior is not intended.
10333 * chartab.c (Fmake_char_table, Fset_char_table_range)
10334 (uniprop_get_decoder, uniprop_get_encoder):
10335 Don't assume fixnum fits in int.
10336 * cmds.c (move_point): New function, that does the gist of
10337 Fforward_char and Fbackward_char, but does so while checking
10338 for integer overflow more accurately.
10339 (Fforward_char, Fbackward_char): Use it.
10340 (Fforward_line, Fend_of_line, internal_self_insert)
10341 (internal_self_insert):
10342 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10343 Fix a FIXME, by checking for integer overflow when calculating
10344 target_clm and actual_clm.

10376 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10377 (consume_chars): Rewrite to not calculate an address outside buffer.
10378 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10379 Don't access memory outside of the args array.
10380 (Fdefine_coding_system_internal): Check for charset-id overflow.
10381 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10382 result of ENCODE_CHAR.
10383 * coding.h: Adjust decls to match defn changes elsewhere.
10384 (struct coding_system):
10385 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10401 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
10402 Do not attempt to compute the address of the object just before a
10403 buffer; this is not portable.
10405 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11095 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11097 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11099 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11101 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11102 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11104 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11105 reference to image_cache->refcount.
11106 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11108 2012-05-17 Juri Linkov <juri@jurta.org>
11110 * search.c (Fword_search_regexp, Fword_search_backward)
11111 (Fword_search_forward, Fword_search_backward_lax)
11112 (Fword_search_forward_lax): Move functions to isearch.el
11113 (bug#10145, bug#11381).
11115 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11117 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11119 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11121 * lread.c (init_obarray): Declare Qt and Qnil as special.
11123 2012-05-14 Glenn Morris <rgm@gnu.org>
11125 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11126 Put "libexec" before "bin", for the sake of init_callproc_1.
11128 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11130 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11132 * unexaix.c: Port to more-recent AIX compilers.
11133 (report_error, report_error_1, make_hdr, copy_sym)
11134 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11135 Make arguments const char *, not char *, to avoid violations of C
11136 standard and to fix some AIX warnings reported by Gilles Pion.
11138 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11140 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11141 already have overlays loaded.
11142 (handle_single_display_spec): Before returning without displaying
11143 fringe bitmap, synchronize the bidi iterator with the main display
11144 iterator, by calling iterate_out_of_display_property.
11145 (iterate_out_of_display_property): Detect buffer iteration by
11146 testing that it->string is a Lisp string.
11147 (get_next_display_element): When the current object is exhausted,
11148 and there's something on it->stack, call set_iterator_to_next to
11149 proceed with what's on the stack, instead of returning zero.
11150 (set_iterator_to_next): If called at the end of a Lisp string,
11151 proceed to consider_string_end without incrementing string
11152 position. Don't increment display vector index past the end of
11153 the display vector. (Bug#11417)
11154 (pos_visible_p): Don't report a position visible when move_it_to
11155 stopped at the last line of window, which happens to be scanned
11156 backwards by the bidi iteration. (Bug#11464)
11158 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11160 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11161 and right-margin display specs even if the spec is invalid or we
11162 are on a TTY, and thus unable to display on the fringes.
11163 That's because the text with the property will not be displayed anyway,
11164 so we need to signal to the caller that this is a "replacing"
11165 display spec. This fixes display when the spec is invalid or we
11168 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11170 * unexaix.c (make_hdr): Fix typo in prototype.
11171 This bug broke the build on AIX. Problem reported by Gilles Pion.
11173 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11175 * keyboard.c (kbd_buffer_get_event): Read special events also in
11176 batch mode. (Bug#11415)
11178 2012-05-12 Glenn Morris <rgm@gnu.org>
11180 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11182 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11184 * lisp.mk (lisp): Add newcomment.elc.
11186 2012-05-12 Glenn Morris <rgm@gnu.org>
11188 * Makefile.in (MKDIR_P): New, set by configure.
11189 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11191 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11193 Remove unused function hourglass_started.
11194 * dispextern.h (hourglass_started):
11195 * w32fns.c (hourglass_started):
11196 * xdisp.c (hourglass_started): Remove.
11198 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11200 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11201 Update dependencies.
11203 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11205 * xgselect.c (xg_select): Put maxfds+1 into a var.
11206 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11208 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11210 2012-05-10 Dave Abrahams <dave@boostpro.com>
11212 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11213 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11215 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11217 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11218 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11219 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11220 Initialize xd_registered_buses.
11222 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11224 Untag more efficiently if USE_LSB_TAG.
11225 This is based on a proposal by YAMAMOTO Mitsuharu in
11226 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11227 For an admittedly artificial (nth 8000 longlist) benchmark on
11228 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11229 Emacs's overall text size by 1%.
11230 * lisp.h (XUNTAG): New macro.
11231 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11232 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11233 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11234 * eval.c (Fautoload):
11235 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11236 * frame.h (XFRAME): Use XUNTAG.
11238 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11239 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11240 Remove unportable assumptions about print widths of types like
11242 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11243 intptr_t when converting between pointer and integer, to avoid GCC
11244 warnings about wrong width.
11246 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11248 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11249 stack for each reader_thread, instead of defaulting to 8MB
11250 determined by the linker. This avoids failures in creating
11251 subprocesses on Windows 7, see the discussion in this thread:
11252 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11254 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11256 Fix up display of the *Minibuf-0* buffer in the mini window.
11257 * keyboard.c (read_char): Don't clear the echo area if there's no
11259 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11260 contents of *Minibuf-0*) if there's no message displayed in its stead.
11262 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11264 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11267 2012-05-06 Chong Yidong <cyd@gnu.org>
11269 * lisp.mk (lisp): Update.
11271 2012-05-05 Jim Meyering <meyering@redhat.com>
11273 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11275 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11277 * data.c (PUT_ERROR): New macro.
11278 (syms_of_data): Use it. Add new error type `user-error'.
11279 * undo.c (user_error): New function.
11280 (Fprimitive_undo): Use it.
11281 * print.c (print_error_message): Adjust print style for `user-error'.
11282 * keyboard.c (user_error): New function.
11283 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11285 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11287 Do not limit current-time-string to years 1000..9999.
11288 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11289 (Fcurrent_time_string): Support any year that is supported by the
11290 underlying localtime representation. Don't use asctime, as it
11291 has undefined behavior for years outside the range -999..9999.
11293 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11295 Fix race conditions involving setenv, gmtime, localtime, asctime.
11296 Without this fix, interrupts could mess up code that uses these
11297 nonreentrant functions, since setting TZ invalidates existing
11298 tm_zone or tzname values, and since most of these functions return
11299 pointers to static storage.
11300 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11301 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11302 Grow the critical sections to include not just invoking
11303 localtime/gmtime, but also accessing these functions' results
11304 including their tm_zone values if any, and any related TZ setting.
11305 (format_time_string): Last arg is now struct tm *, not struct tm **,
11306 so that the struct tm is saved in the critical section.
11307 All callers changed. Simplify allocation of initial buffer, partly
11308 motivated by the fact that memory allocation needs to be outside
11309 the critical section.
11311 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11313 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11314 with RESET_INTERVAL.
11316 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11317 Remove duplicated buffer name initialization.
11319 2012-05-02 Jim Meyering <jim@meyering.net>
11321 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11323 * xfns.c (x_window): Use xstrdup (Bug#11375).
11325 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11327 * xdisp.c (pos_visible_p): If already at a newline from the
11328 display string before the 'while' loop, don't walk back the glyphs
11329 from it3.glyph_row. Solves assertion violation when the display
11330 string begins with a newline (egg.el). (Bug#11367)
11332 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11334 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11337 2012-05-01 Glenn Morris <rgm@gnu.org>
11339 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11340 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11341 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11342 All were removed before 23.1.
11344 * dispnew.c: Remove HAVE_LIBNCURSES test;
11345 it is always true on relevant platforms.
11347 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11348 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11350 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11352 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11354 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11355 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11358 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11360 Do not avoid creating empty evaporating overlays (Bug#9642).
11361 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11362 That is, do not delete an evaporating overlay if it becomes
11363 empty after its bounds are adjusted to fit within its buffer.
11364 This fix caused other problems, and I'm reverting it until we get
11365 to the bottom of them.
11367 2012-04-27 Chong Yidong <cyd@gnu.org>
11369 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11371 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11373 * xdisp.c (pos_visible_p): If the window start position is beyond
11374 ZV, start the display from buffer beginning. Prevents assertion
11375 violation in init_iterator when the minibuffer window is scrolled
11376 via the scroll bar.
11378 * window.c (window_scroll_pixel_based): Likewise.
11380 2012-04-27 Chong Yidong <cyd@gnu.org>
11382 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11384 2012-04-27 Glenn Morris <rgm@gnu.org>
11386 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11387 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11389 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11391 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11392 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11394 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11396 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11397 display element, check also the underlying string or buffer
11398 character. (Bug#11341)
11400 * w32menu.c: Include w32heap.h.
11401 (add_menu_item): If the call to AppendMenuW (via
11402 unicode_append_menu) fails, disable Unicode menus only if we are
11403 running on Windows 9X/Me.
11405 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11407 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11408 (xgetint): Add missing shift for LSB tags.
11410 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11412 * keyboard.c (read_char): Don't wipe echo area for select window
11413 events: These might get delayed via `mouse-autoselect-window'
11416 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11418 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11419 manipulation of :loaded-from data.
11421 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11423 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11424 now a cons (bug#11311).
11426 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11428 Do not create empty overlays with the evaporate property (Bug#9642).
11429 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11430 if it becomes empty after its bounds are adjusted to fit within
11431 its buffer. Without this fix, in a nonempty buffer (let ((o
11432 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11433 yields an empty overlay that has the evaporate property, which is
11434 not supposed to happen.
11436 Fix minor GTK3 problems found by static checking.
11437 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11438 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11439 (struct _EmacsFixedClass, emacs_fixed_get_type):
11440 Move decls here from emacsgtkfixed.h, since they needn't be public.
11441 (emacs_fixed_get_type): Now static.
11442 (emacs_fixed_class_init): Omit unused local.
11443 (emacs_fixed_child_type): Remove; unused.
11444 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11445 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11446 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11447 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11448 (EMACS_FIXED_GET_CLASS): Remove; unused.
11449 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11451 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11452 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11454 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11456 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11457 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11458 (__malloc_size_t, __malloc_ptrdiff_t):
11459 Remove. All uses removed, replaced by the definiens if needed,
11460 since we can assume C89 or better now.
11461 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11469 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11470 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11471 Define using prototypes, not old style.
11472 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11473 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11474 (align): Don't assume that signed integer overflow wraps around.
11475 Omit unused local var.
11476 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11477 (_free_internal_nolock, memalign, mallochook, reallochook):
11478 Omit no-longer-needed casts.
11479 (valloc): Use getpagesize, not __getpagesize.
11480 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11481 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11483 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11485 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11487 Move functions from C to Lisp. Make non-blocking method calls
11488 the default. Implement further D-Bus standard interfaces.
11490 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

11506 (xd_signature, xd_append_arg): Allow float for integer types.
11507 (xd_get_connection_references): New function.
11508 (xd_get_connection_address): Rename from xd_initialize.
11509 Return cached address.
11510 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
11511 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp
11513 (Fdbus_init_bus): New optional arg PRIVATE. Cache address.
11514 Return number of refcounts.
11515 (Fdbus_get_unique_name): Make stronger parameter check.
11516 (Fdbus_message_internal): New defun.

11545 2012-04-22 Leo Liu <sdl.web@gmail.com>
11547 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
11549 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11551 * sysdep.c [__FreeBSD__]: Minor cleanups.
11552 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11553 Use Emacs indenting style more consistently. Avoid some casts.
11554 Use 'double' consistently rather than mixing 'float' and 'double'.

11558 * sysdep.c (list_system_processes, system_process_attributes):
11559 Add implementation for FreeBSD (Bug#5243).

11565 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11567 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11568 It is never used otherwise.
11570 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11572 * print.c (print_preprocess): Only check print_depth if print-circle
11574 (print_object): Check for cycles even when print-circle is nil and
11575 print-gensym is t, but only check print_depth if print-circle is nil.
11577 2012-04-20 Chong Yidong <cyd@gnu.org>
11579 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11580 set the status to "failed" and ensure that sentinel is run.
11582 2012-04-20 Glenn Morris <rgm@gnu.org>
11584 * process.c (Fset_process_inherit_coding_system_flag)
11585 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

11593 row, return zero immediately.
11594 (try_cursor_movement): If inside continuation line, don't back up
11595 farther than the first row after the header line, if any.
11596 Don't consider the header-line row as "partially visible", even if
11597 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
11599 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

11611 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
11612 * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
11613 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11614 -Wunused-result, -Wunused-variable. This should go away once
11615 the Emacs and Gnulib regex code is merged.
11616 (xmalloc, xrealloc): Now static.
11618 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

11635 New extern decls, to avoid calling undeclared functions.
11636 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11637 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11638 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11639 (NEED_MEM_INSERT): New macro.
11640 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11641 Remove one incorrect comment and fix another.

11656 Remove decls. This fixes an "It stinks!".
11658 * alloc.c (which_symbols): Fix alignment issue / type clash.
11660 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11662 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11663 (struct Lisp_Misc_Any): Likewise.
11664 (struct Lisp_Free): Likewise.
11665 * alloc.c (union aligned_Lisp_Symbol): Define.

11677 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11678 * s/netbsd.h, s/sol2-6.h:
11679 Remove definition of GC_MARK_STACK, since the default now works.
11680 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

11682 no longer the default.
11683 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11685 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11687 * lread.c (lisp_file_lexically_bound_p):
11688 Fix hang at ";-*-\n" (bug#11238).
11690 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11692 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
11693 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

11706 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11708 2012-04-11 Daniel Colascione <dancol@dancol.org>
11710 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11711 against is gone. It's better to use vfork now so that when Cygwin
11712 gains a new, working vfork, we use it automatically (bug#10398).
11714 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11716 * window.c (save_window_save): Obey window-point-insertion-type.

11734 * w32.c (w32_delayed_load): Record the full path of the library
11735 being loaded (bug#10424).
11737 2012-04-09 Glenn Morris <rgm@gnu.org>
11739 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11740 not just in the obarray, before snarfing them. (Bug#11036)

11757 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11758 attempts per process (connection).
11760 2012-04-09 Chong Yidong <cyd@gnu.org>
11762 * eval.c (Fuser_variable_p, user_variable_p_eh)

11764 (Fdefvar): Caller changed.
11766 * callint.c (Finteractive, Fcall_interactively):
11767 * minibuf.c (Fread_variable): Callers changed.
11769 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11771 * xdisp.c (set_cursor_from_row): If the display string appears in
11772 the buffer at position that is closer to point than the position
11773 after the display string, display the cursor on the first glyph of
11774 the display string. Fixes cursor display when a 'display' text
11775 property immediately follows invisible text. (Bug#11094)
11777 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11779 composite.c: use 'double' consistently
11780 * composite.c (get_composition_id): Use 'double' consistently
11781 instead of converting 'float' to 'double' and vice versa; this is
11782 easier to understand and avoids a GCC warning.
11784 2012-04-09 Glenn Morris <rgm@gnu.org>
11786 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11787 preparation for dumping it with emacs. (Bug#4789)

11808 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11809 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11810 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11811 objects, as mark_maybe_pointer will catch them otherwise.
11812 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11813 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

11824 * makefile.w32-in (OBJ2): Add xml.$(O).
11825 (GLOBAL_SOURCES): Add xml.c.
11826 ($(BLD)/xml.$(O)): New dependency list.
11828 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11829 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11830 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11831 [!WINDOWSNT]: New macros.
11832 (init_libxml2_functions, libxml2_loaded_p): New functions.
11833 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11834 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11835 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11836 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11838 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11839 Call init_libxml2_functions before calling libxml2 functions.
11840 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11842 * emacs.c: Don't include libxml/parser.h.
11843 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11844 xmlCleanupParser directly.

11848 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11850 * indent.c (Fvertical_motion): If there is a display string at
11851 point, use it.vpos to compute how many lines to backtrack after
11852 move_it_to point. (Bug#11133)
11854 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11856 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11857 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11858 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11859 macros related to unification of CJK characters. For the details,
11860 see the discussion following the message here:
11861 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11863 2012-04-04 Chong Yidong <cyd@gnu.org>
11865 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11867 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11869 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

11877 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11879 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11880 position we get to after a call to move_it_to fails the
11881 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11882 only if we wind up in a string from display property. (Bug#11063)
11884 * window.c (Fdelete_other_windows_internal): Invalidate the row
11885 and column information about mouse highlight, so that redisplay
11886 restores it after reallocating the glyph matrices. (Bug#7464)
11888 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11889 string comes from a `display' text property, use the buffer
11890 position of that property as if we actually saw that position in
11892 (move_it_by_lines): Remove the assertion that
11893 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11894 violated when there's a before-string at the beginning of a line.
11897 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11899 * xdisp.c (append_space_for_newline): If the default face was
11900 remapped, use the remapped face for the appended newline.
11901 (extend_face_to_end_of_line): Use the remapped default face for
11902 extending the face to the end of the line.
11903 (display_line): Call extend_face_to_end_of_line when the default
11904 face was remapped. (Bug#11068)
11906 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11908 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11910 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

11926 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11927 (command_loop_1): Use it; inhibit selection update for

11932 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11934 2012-03-25 Kenichi Handa <handa@m17n.org>
11936 * dispextern.h (struct glyph): Change the bit length of
11937 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11939 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11941 * s/ms-w32.h (tzname): Include time.h before redirecting to

11950 !SYNC_INPUT. (Bug#11080)
11952 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11954 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11955 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11956 when fetching a multibyte character consumes more bytes than
11957 CHAR_BYTES returns, due to unification of CJK characters in
11958 string_char. (Bug#11073)
11960 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11962 * process.c (wait_reading_process_output): Handle pty disconnect
11963 by refraining from sending oneself a SIGCHLD (bug#10933).
11965 2012-03-22 Chong Yidong <cyd@gnu.org>
11967 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11969 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

11991 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
11992 it fit in a valid range (Bug#11003).
11994 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11996 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11997 that is not from display property, accept the row as a "cursor
11998 row" if one of the string's character has a non-nil `cursor'
11999 property. Fixes cursor positioning when there are newlines in
12000 overlay strings, e.g. in icomplete.el. (Bug#11035)
12002 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12004 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

12036 2012-03-03 Glenn Morris <rgm@gnu.org>
12038 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12040 2012-03-02 Eli Zaretskii <eliz@gnu.org>

12043 position past the first glyph_row that ends at ZV. (Bug#10902)
12044 (redisplay_window, next_element_from_string): Fix typos in
12046 (redisplay_window): Pass to move_it_vertically the margin in
12047 pixels, not in screen lines.
12049 2012-03-02 Glenn Morris <rgm@gnu.org>
12051 * buffer.c (buffer-list-update-hook): Doc fix.
12053 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12055 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12056 push_it before setting up the iterator for the first overlay
12057 string, even if we have an empty string loaded.
12058 (next_overlay_string): If there's an empty string on the iterator
12059 stack, pop the stack. (Bug#10903)
12061 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12063 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12064 Suggested by Stefan Monnier in
12065 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12066 * alloc.c (widen_to_Lisp_Object): New static function.
12067 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12068 and widening them to Lisp_Objects. This would work even if
12069 USE_LSB_TAG is defined and wide integers are used, which might
12070 happen in a future version of Emacs.
12072 2012-02-25 Chong Yidong <cyd@gnu.org>
12074 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12079 before saving to clipboard manager.
12081 2012-02-24 Chong Yidong <cyd@gnu.org>
12083 * keyboard.c (process_special_events): Handle all X selection
12084 requests in kbd_buffer, not just the next one (Bug#8869).
12086 2012-02-23 Chong Yidong <cyd@gnu.org>
12088 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12089 call when setting menu-bar-lines and tool-bar-lines parameters.
12090 (unwind_create_frame_1): New helper function.
12092 * window.c (inhibit_window_configuration_change_hook): New var.

12103 * fileio.c (Vfile_name_handler_alist): Doc fix.
12105 * buffer.c (Fget_file_buffer): Protect against invalid file
12106 handler return value.

12111 when computing $valmask.
12113 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12114 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12115 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12116 It's useless in that case, and it can cause problems on hosts
12117 that allocate halves of EMACS_INT values separately.
12118 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12119 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12120 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12121 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12122 it avoids undefined behavior on hosts where shifting right by more
12123 than the word width has undefined behavior.
12125 2012-02-19 Chong Yidong <cyd@gnu.org>
12127 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12128 (Funhandled_file_name_directory, Ffile_name_as_directory)
12129 (Fdirectory_file_name, Fexpand_file_name)
12130 (Fsubstitute_in_file_name): Protect against invalid file handler
12131 return values (Bug#10845).

12145 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12147 2012-02-15 Chong Yidong <cyd@gnu.org>
12149 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12150 marked as special. Also, starting docstrings with * is obsolete.

12165 2012-02-12 Chong Yidong <cyd@gnu.org>
12167 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12168 as that creates a dangerous corner case.
12170 * window.c (Fdelete_window_internal): Invalidate the mouse
12171 highlight (Bug#9904).
12173 2012-02-12 Glenn Morris <rgm@gnu.org>

12178 * nsselect.m (Fx_own_selection_internal)
12179 (Fx_disown_selection_internal, Fx_selection_exists_p)
12180 (Fx_selection_owner_p, Fx_get_selection_internal):
12181 Sync docs and argument specs with the xselect.c versions.
12183 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

12203 2012-02-07 Chong Yidong <cyd@gnu.org>
12205 * buffer.c (Fbuffer_local_variables)
12206 (buffer_lisp_local_variables): Handle unbound vars correctly;
12207 don't let Qunbound leak into Lisp.
12209 2012-02-07 Glenn Morris <rgm@gnu.org>
12211 * image.c (Fimagemagick_types): Doc fix.
12213 * image.c (imagemagick-render-type): Change it from a lisp object
12214 to an integer. Move the doc here from the lisp manual.

12231 2012-02-04 Eli Zaretskii <eliz@gnu.org>
12233 * w32.c (get_emacs_configuration_options):
12234 Include --enable-checking, if specified, in the return value.

12244 before BEGV. (Bug#10696)
12246 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12248 Handle overflow when computing char display width (Bug#9496).
12249 * character.c (char_width): Return EMACS_INT, not int.
12250 (char_width, c_string_width): Check for overflow when
12251 computing the width; this is possible now that individual
12252 characters can have unbounded width. Problem introduced
12253 by merge from Emacs 23 on 2012-01-19.

12277 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12279 (x_produce_glyphs): If the component of a composition is a null

12284 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12285 first 2 arguments are identical. This makes inserting large
12286 output from a subprocess an order of magnitude faster on
12287 MS-Windows, where all sbrk'ed memory is always contiguous.
12289 2012-01-31 Glenn Morris <rgm@gnu.org>

12386 * xdisp.c (rows_from_pos_range): Accept additional argument
12387 DISP_STRING, and accept any glyph in a row whose object is that
12388 string as eligible for mouse highlight. Fixes mouse highlight of
12389 display strings from overlays. (Bug#10464)
12391 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
12393 emacs: fix an auto-save permissions race condition (Bug#10400)

12395 (Fmake_directory_internal): Use it.
12396 (do_auto_save_make_dir): Set it, instead of invoking chmod after

12740 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12741 verifies glyph row's hash code--we have just reallocated the

12903 Otherwise, valgrind does not work on some platforms.
12904 Problem reported by Andreas Schwab in
12905 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12906 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12907 is set, removing the need for VIRT_ADDRESS_VARIES.
12908 (PURE_P): Use a more-efficient implementation that needs just one
12909 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12910 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12911 to 4 (xorl, subq, cmpq, setbe).
12912 * alloc.c (pure): Always extern now, since that's the
12913 VIRT_ADDR_VARIES behavior.
12914 (PURE_POINTER_P): Use a single comparison, not two, for
12915 consistency with the new puresize.h.
12916 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12917 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

12922 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
12923 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12924 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12925 behave as if the cursor position were at the window margin.
12927 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12928 and the cursor position is out of bounds, behave as if the cursor
12929 position were at the window margin. (Bug#10075)
12931 2011-11-18 Chong Yidong <cyd@gnu.org>
12933 * window.c (Fwindow_combination_limit): Make first argument
12934 non-optional, since it is meaningless for live windows like the
12937 2011-11-18 Dmitry Antipov <dmantipov@yandex.ru>

13395 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13396 instead of calling the "wide" APIs directly.
13398 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13400 * w32.h (syms_of_w32font): Add prototype.
13402 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13404 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13405 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13406 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13407 (Fmove_to_window_line): Doc fix.
13409 2011-10-27 Chong Yidong <cyd@gnu.org>
13411 * process.c (make_process): Set gnutls_state to NULL.
13413 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13414 non-NULL, regardless of GNUTLS_INITSTAGE.
13415 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13416 an error. Set process slots as soon as we allocate them.
13418 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13420 2011-10-27 Chong Yidong <cyd@gnu.org>
13422 * gnutls.c (emacs_gnutls_deinit): New function.
13423 Deallocate credentials structures as well as calling gnutls_deinit.
13424 (Fgnutls_deinit, Fgnutls_boot): Use it.
13426 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13427 (deactivate_process): Call emacs_gnutls_deinit.
13429 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13431 * image.c (x_create_x_image_and_pixmap):
13432 * w32.c (sys_rename, w32_delayed_load):
13433 * w32font.c (fill_in_logfont):
13434 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13436 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13438 * w32fns.c (w32_default_color_map): New function,
13439 extracted from Fw32_default_color_map.
13440 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13442 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13444 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13446 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13448 * keyboard.c (test_undefined): New function (bug#9751).
13449 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13451 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13453 * sysdep.c (init_sys_modes): Fix the check for the controlling
13454 terminal (Bug#6649).
13456 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13458 * dispextern.h (struct bidi_it): New member next_en_type.
13460 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13461 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13462 current character, check also for next_en_type being WEAK_EN.
13463 (bidi_resolve_weak): Don't enter the expensive loop if the current
13464 position is before next_en_pos. Record the bidi type of the first
13465 non-ET, non-BN character we find, in addition to its position.
13466 (bidi_level_of_next_char): Invalidate next_en_type when
13467 next_en_pos is over-stepped.
13469 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13471 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13472 * editfns.c: Rewrite current-time-zone so that it invokes
13473 the equivalent of (format-time-string "%Z") to get the time zone name.
13474 This fixes a bug when the time zone name contains characters that
13475 need converting from the system time locale to Emacs internal format.
13476 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13477 that patch fixed format-time-string to do the conversion, but
13478 I forgot to fix current-time-zone.
13479 (format_time_string): New function, containing most of
13480 what Fformat_time_string used to contain.
13481 (Fformat_time_string): Rewrite in terms of format_time_string.
13482 This doesn't change this function's behavior.
13483 (current-time-zone): Rewrite to use format_time_string.
13484 This fixes the bug reported by Michael Schierl in
13485 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13486 Jason Rumney's 2007-06-07 change worked around this bug, but
13488 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13490 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13492 * xdisp.c (start_display): If the character at POS is displayed
13493 via a display vector, reset IT->current.dpvec_index to zero.
13494 (try_window_reusing_current_matrix): If a line ends in a display
13495 vector or the next line starts in a display vector, continue
13496 redrawing the window even though the character position of
13497 start_row was reached.
13500 2011-10-18 Chong Yidong <cyd@gnu.org>
13502 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13503 with nobreak-char-display too.
13505 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13507 Fix part 3 of bug#9771.
13508 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13509 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13510 non-neutral characters if the current character is a paragraph
13511 separator (a.k.a. Newline). This avoids running the same
13512 expensive loop twice, once when we consume the preceding newline
13513 and the other time when the line actually needs to be displayed.
13514 Avoid the loop when we see neutrals on the base embedding level
13515 following a character whose directionality is the same as the
13516 paragraph's. This avoids running the expensive loop when a line
13517 ends in a long sequence of neutrals, like control characters.
13518 Add assertion against STRONG_AL type. Slightly rearrange code
13519 that determines the type of a neutral given the first non-neutral
13521 (bidi_level_of_next_char): Set next_en_pos to zero when
13522 invalidating its info.
13524 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13526 * xdisp.c (push_display_prop): Determine whether to record string
13527 or buffer position by IT->string, not by IT->method. Allow
13528 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13529 (move_it_vertically_backward): Don't look for character position
13530 immediately after the newline when in a continuation line.
13533 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13535 * window.c (coordinates_in_window): Rewrite and delabelize
13536 vertical border check. (Bug#5357) (Bug#9618)
13538 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13540 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13541 errors in XSetWindowBorder (bug#9310).
13543 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13545 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13546 avoid crash when xmalloc overrun checking is enabled.
13548 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13550 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13551 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13552 cursor motion with <left> and <right> arrow keys.
13554 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13555 some callers set that themselves.
13557 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13559 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13560 display string and the previous row comes from the same string and
13561 is empty. (Bug#9739) (Bug#9738)
13563 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13565 * doc.c (get_doc_string): Encode file name (bug#9735).
13567 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13569 * bidi.c (bidi_level_of_next_char):
13570 * xdisp.c (get_visually_first_element): Remove old incorrect
13571 comments regarding the Unicode Line Separator character.
13573 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13575 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13577 * alloc.c (Fgc_status): Do not access beyond zombies array
13578 boundary if nzombies > MAX_ZOMBIES.
13579 * alloc.c (dump_zombies): Add missing format specifier.
13581 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13583 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13584 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13586 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13587 Some packages use them to denote characters with modifiers.
13589 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13591 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13592 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13593 matching a pp-number. Rename parameter var to var1.
13595 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13597 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13599 2011-10-08 Glenn Morris <rgm@gnu.org>
13601 * callint.c (Fcall_interactively): Give a more explicit error for the
13602 'c' case with a non-character input. (Bug#8479)
13604 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13606 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13608 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13609 lines that are hscrolled on the left.
13611 * dispnew.c (buffer_posn_from_coords): Account for a possible
13612 presence of header-line. (Bug#4426)
13614 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13616 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13617 Don't advertise functionality which we discourage or doesn't work.
13619 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13621 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13622 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13623 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13624 this makes Emacs dump core during garbage collection on rare
13625 occasions. sizeof is obviously inferior to offsetof here, so
13626 stick with offsetof.
13627 (GC_POINTER_ALIGNMENT): New macro.
13628 (mark_memory): Omit 3rd (offset) arg; caller changed.
13629 Don't assume EMACS_INT alignment is the same as pointer alignment.
13631 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13633 * keyboard.c (read_key_sequence_remapped): New var.
13634 (read_key_sequence): Compute remapping in the right buffer.
13635 (command_loop_1): Use read_key_sequence's remapping directly.
13637 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13639 * dired.c (file_name_completion): Don't expand file name.
13640 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13641 before checking file name handler.
13643 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13644 they've been requested explicitly (bug#9591).
13646 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13648 * keymap.c (Fsingle_key_description): Use make_specified_string
13649 instead of build_string to build string from push_key_description.
13652 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13654 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13655 This fixes a Y2038 bug on 64-bit hosts.
13656 * buffer.c (reset_buffer):
13657 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13658 (Fclear_buffer_auto_save_failure):
13659 Use 0, not -1, to represent an unset failure time, since time_t
13660 might not be signed.
13662 Remove dependency on glibc malloc internals.
13663 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13664 Move back here from lisp.h, but with their new implementations.
13665 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13666 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13667 * charset.c (charset_table_init): New static var.
13668 (syms_of_charset): Use it instead of xmalloc. This removes a
13669 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13670 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13671 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13672 Move back to alloc.c.
13673 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13674 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13676 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13678 * nsterm.m (windowDidResize): Call x_set_window_size only when
13679 ns_in_resize is true. Otherwise set pixelwidth/height and
13680 call change_frame_size (Bug#9628).
13682 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13684 Port --enable-checking=all to Fedora 14 x86-64.
13685 * charset.c (syms_of_charset): Also account for glibc malloc's
13686 internal overhead when calculating the initial malloc maximum.
13688 Port --enable-checking=all to Fedora 14 x86.
13689 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13691 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13692 (overrun_check_realloc, overrun_check_free):
13693 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13694 That way, xmalloc returns a properly-aligned pointer even if
13695 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13696 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13697 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13698 into account when calculating the initial malloc maximum.
13699 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13700 Move here from alloc.c, so that charset.c can use it too.
13701 Properly align; the old code wasn't right for common 32-bit hosts
13702 when configured with --enable-checking=all.
13703 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13704 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13706 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13708 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13711 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13713 * xdisp.c (compute_display_string_end): If there's no display
13714 string at CHARPOS, return -1.
13716 * bidi.c (bidi_fetch_char): When compute_display_string_end
13717 returns a negative value, treat the character as a normal
13718 character not covered by a display string. (Bug#9624)
13720 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13722 * lread.c (Fread_from_string): Fix typo in docstring.
13724 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13726 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13727 newline, reseat the iterator instead of bidi-iterating there one
13728 character at a time. (Bug#9610)
13729 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13730 TO_CHARPOS if the bidi iterator is at base embedding level.
13732 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13734 * lread.c (readevalloop): Use correct code for NBSP.
13735 (read1): Likewise. (Bug#9608)
13737 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13739 * dbusbind.c (Fdbus_register_signal): When service is not
13740 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13742 2011-09-25 Glenn Morris <rgm@gnu.org>
13744 * buffer.c (truncate-lines): Doc fix.
13746 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13748 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13749 (Fset_window_next_buffers): Doc fix.
13751 2011-09-24 Glenn Morris <rgm@gnu.org>
13753 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13755 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13757 Fix minor problems found by static checking.
13758 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13759 * indent.c (Fvertical_motion): Fix == vs = typo.
13761 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13763 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13764 Default value is now t. Doc fix.
13766 * indent.c (Fvertical_motion): Compute and apply the overshoot
13767 logic when moving up, not only when moving down. Fix the
13768 confusing name and values of the it_overshoot_expected variable;
13769 logic changes accordingly. (Bug#9254) (Bug#9549)
13771 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13772 CHARPOS is covered by a display string which includes newlines.
13773 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13774 is covered by a display string with embedded newlines.
13776 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13778 * dbusbind.c (Fdbus_register_signal): Add match rule to
13779 Vdbus_registered_objects_table. (Bug#9581)
13780 (Fdbus_register_method, Vdbus_registered_objects_table):
13783 2011-09-24 Jim Meyering <meyering@redhat.com>
13785 do not ignore write error for any output size
13786 The previous change was incomplete.
13787 While it makes emacs --batch detect the vast majority of stdout
13788 write failures, errors were still ignored whenever the output size is
13789 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13790 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13791 && echo FAIL: ignored write error
13792 FAIL: ignored write error
13793 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13794 && echo FAIL: ignored write error
13795 FAIL: ignored write error
13796 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13798 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13800 * emacs.c (Fkill_emacs): In noninteractive mode exit
13801 non-successfully if a write error occurred on stdout. (Bug#9574)
13803 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13805 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13808 * dispextern.h (struct it): Update the comment documenting what
13811 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13813 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13814 a display string, extend search for cursor position to end of row.
13815 (find_row_edges): If the row ends in a newline from a display
13816 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13817 Handle the case of a display string with multiple newlines.
13818 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13819 non-empty line. Fixes confusing cursor motion with arrow keys at
13820 the beginning of a line that starts with whitespace.
13822 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13824 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13827 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13829 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13830 boolean (Bug#9154).
13832 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13834 * xdisp.c (display_line): Record maximum and minimum buffer
13835 positions even if no glyphs were produced (e.g., by a zero-width
13836 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13837 buffer positions that will be removed from the glyph row because
13839 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13840 column is beyond frame width: don't subtract 1 "pixel" when
13841 computing width of the stretch.
13842 (reseat_at_next_visible_line_start): Undo the change made on
13843 2011-09-17 that saved paragraph information and restored it after
13844 the call to `reseat'. (Bug#9545)
13846 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13848 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13849 and turn window cursor on if cleared (Bug#9415).
13851 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13853 * search.c (boyer_moore): Take unibyte characters from pattern
13854 literally. (Bug#9458)
13856 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13858 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13860 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13862 Fix minor problem found by static checking.
13863 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13864 initialized, to pacify gcc -Wuninitialized.
13866 * fileio.c: Report proper errno when syscall falls.
13867 (Finsert_file_contents): Save and restore errno,
13868 so that report_file_error outputs the correct diagnostic.
13869 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13871 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13873 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13875 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13877 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13878 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13880 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13882 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13883 about the current paragraph and restore it after the call to reseat.
13885 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13886 (bidi_find_paragraph_start): Search back for paragraph beginning
13887 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13888 (bidi_move_to_visually_next): Only trigger paragraph-related
13889 computations when the last character is a newline or at EOB, not
13890 just any NEUTRAL_B. (Bug#9470)
13892 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13893 truncated lines if point is covered by a display string. (Bug#9524)
13895 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13897 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13898 (cons_to_x_long): New function.
13899 (lisp_data_to_selection_data): Use it. Correct the test for
13900 short-versus-long data; it was negated. Break out of vector
13901 loop, for efficiency, when a long datum is discovered.
13903 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13905 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13907 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13909 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13910 GCC PR/17406) by declaring this function with external scope.
13912 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13914 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13915 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13917 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13919 * editfns.c (Fformat): Correctly handle text properties on "%%".
13921 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13923 * xterm.c (x_draw_composite_glyph_string_foreground):
13924 * w32term.c (x_draw_composite_glyph_string_foreground):
13925 * term.c (encode_terminal_code):
13926 * composite.c (composition_update_it, get_composition_id):
13927 * xdisp.c (get_next_display_element)
13928 (fill_composite_glyph_string): Add comments about special meaning
13929 of TAB characters in a composition.
13931 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13933 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13934 This occurs when processing a multibyte format.
13935 Problem reported by Wolfgang Jenker.
13937 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13939 * xdisp.c (try_cursor_movement): Only check for exact match if
13940 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13942 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13944 Remove unused external symbols.
13945 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13946 * xdisp.c (calc_pixel_width_or_height): Now static.
13947 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13948 * indent.c (check_display_width):
13949 * w32term.c: Fix comment to match code.
13950 * xterm.c, xterm.h (x_catching_errors): Remove.
13952 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13954 * xselect.c: Use signed conversions more consistently (Bug#9498).
13955 (selection_data_to_lisp_data): Assume incoming selection data are
13956 signed integers, not unsigned. This is to be consistent with
13957 outgoing selection data, which was modified to use signed integers
13958 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13959 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13960 expects long, not unsigned long.
13962 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13964 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13965 computation of loop end. Reported by Johan Bockgård
13968 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13970 * frame.c (Fother_visible_frames_p): Function deleted.
13972 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13974 * indent.c (compute_motion): Process display vector front to back
13975 rather than the other way around. (Bug#2496)
13977 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13979 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13981 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13983 * minibuf.c (Fread_from_minibuffer): Doc fix.
13985 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13987 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13988 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13990 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13992 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13993 value for non-existent files.
13995 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13997 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13998 set its "size" to -1. This will set the modtime_size field of
13999 the corresponding buffer to -1, which is what
14000 verify-visited-file-modtime expects for files that do not exist.
14003 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14005 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14007 * lisp.h: ... from here. push_key_description is no longer
14008 defined in keyboard.c, so its declaration should not be in
14009 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14010 logically belongs with push_key_description.
14012 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14014 * buffer.h: Include <sys/types.h> instead of <time.h>.
14015 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14016 Problem reported by Herbert J. Skuhra.
14018 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14020 * xml.c (parse_region): Make the parsing work for
14021 non-comment-starting XML files again (bug#9144).
14023 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14025 * image.c (gif_load): Fix calculation of bottom and right corner.
14028 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14030 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14031 redisplay in small windows.
14033 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14035 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14037 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14039 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14040 Operate on live windows only.
14042 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14044 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14046 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14048 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14049 only under bidi iteration.
14051 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14053 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14055 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14057 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14058 Without this fix, the command to link temacs failed due to an
14059 undefined symbol __builtin_isnan. This is because
14060 /usr/include/iso/math_c99.h #defines isnan(x) to
14061 __builtin_isnan(x), but the bundled gcc, which identifies itself
14062 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14064 * floatfns.c (isnan): #undef, and then #define to a clone of
14066 (Fisnan): Always define, since it's always available now.
14067 (syms_of_floatfns): Always define isnan at the Lisp level.
14069 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14071 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14073 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14075 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14076 The previous code assumed that file offsets (off_t values) fit in
14077 EMACS_INT variables, which is not true on typical 32-bit hosts.
14078 The code messed up by falsely reporting buffer overflow in cases
14079 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14080 when "big" contains more than 2**29 bytes, even though this
14081 inserts just one byte and does not overflow the buffer.
14082 (Finsert_file_contents): Store file offsets as off_t
14083 values, not as EMACS_INT values. Check for overflow when
14084 converting between EMACS_INT and off_t. When checking for
14085 buffer overflow or for overlap, take the offsets into account.
14086 Don't use EMACS_INT for small values where int suffices.
14087 When checking for overlap, fix a typo: ZV was used where
14088 ZV_BYTE was intended.
14089 (Fwrite_region): Don't assume off_t fits into 'long'.
14090 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14092 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14094 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14096 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14098 sprintf-related integer and memory overflow issues (Bug#9412).
14100 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14101 (esprintf, exprintf, evxprintf): New functions.
14102 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14103 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14104 (modify_event_symbol): Do not assume that the length of
14105 name_alist_or_stem is safe to alloca and fits in int.
14106 (Fexecute_extended_command): Likewise for function name and binding.
14107 (Frecursion_depth): Wrap around reliably on integer overflow.
14108 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14109 since some callers pass EMACS_INT values.
14110 (Fsingle_key_description): Don't crash if symbol name contains more
14111 than MAX_ALLOCA bytes.
14112 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14113 (get_minibuffer): Arg is now EMACS_INT, not int.
14114 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14115 (esprintf, exprintf, evxprintf): New decls.
14116 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14118 * dbusbind.c (signature_cat): New function.
14119 (xd_signature, Fdbus_register_signal):
14120 Do not overrun buffer; instead, report string overflow.
14122 * dispnew.c (add_window_display_history): Don't overrun buffer.
14123 Truncate instead; this is OK since it's just a log.
14125 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14126 even if the time zone offset is outlandishly large.
14127 Don't mishandle offset == INT_MIN.
14129 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14130 when creating daemon; the previous buffer-overflow check was incorrect.
14132 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14133 which has the guts of the old verror function.
14135 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14136 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14138 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14139 (font_unparse_xlfd): Don't blindly alloca long strings.
14140 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14141 fits in int, when using sprintf. Use single snprintf to count
14142 length of string rather than counting it via multiple sprintfs;
14143 that's simpler and more reliable.
14144 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14145 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14146 sprintf, in case result does not fit in int.
14148 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14149 (fontset_from_font): Print it.
14151 * frame.c (tty_frame_count): Now printmax_t, not int.
14152 (make_terminal_frame, set_term_frame_name): Print it.
14153 (x_report_frame_params): In X, window IDs are unsigned long,
14154 not signed long, so print them as unsigned.
14155 (validate_x_resource_name): Check for implausibly long names,
14156 and don't assume name length fits in 'int'.
14157 (x_get_resource_string): Don't blindly alloca invocation name;
14158 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14161 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14162 (xg_check_special_colors, xg_set_geometry):
14163 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14165 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14166 Use esprintf, not sprintf, in case result does not fit in int.
14168 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14169 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14170 it as a large positive number.
14171 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14172 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14174 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14175 in case result does not fit in int.
14177 * print.c (float_to_string): Detect width overflow more reliably.
14178 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14179 buffer overrun. Don't assume list length fits in 'int'. Treat
14180 print length of 0 as 0, not as infinity; to be consistent with other
14181 uses of print length in this function. Don't overflow print length
14182 index. Don't assume hash table size fits in 'long', or that
14183 vectorlike size fits in 'unsigned long'.
14185 * process.c (make_process): Use printmax_t, not int, to format
14186 process-name gensyms.
14188 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14190 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14191 to avoid potential buffer overrun.
14193 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14194 if X resource line is longer than 512 bytes.
14196 * xfns.c (x_window): Make sprintf buffer a bit bigger
14197 to avoid potential buffer overrun.
14199 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14201 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14203 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14205 Integer overflow fixes for scrolling, etc.
14206 Without these, Emacs silently mishandles large integers sometimes.
14207 For example, "C-u 4294967297 M-x recenter" was treated as if
14208 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14210 * xdisp.c (try_window_id): Check Emacs fixnum range before
14211 converting to 'int'.
14213 * window.c (window_scroll_line_based, Frecenter):
14214 Check that an Emacs fixnum is in range before assigning it to 'int'.
14215 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14216 values converted from Emacs fixnums.
14217 (Frecenter): Don't wrap around a line count if it is out of 'int'
14218 range; instead, treat it as an extreme value.
14219 (Fset_window_configuration, compare_window_configurations):
14220 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14222 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14223 that can exceed INT_MAX. Check that EMACS_INT value is in range
14224 before assigning it to the (possibly-narrower) index.
14225 (match_limit): Don't assume that a fixnum can fit in 'int'.
14227 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14230 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14231 (Fvertical_motion): Don't wrap around LINES values that don't fit
14232 in 'int'. Instead, treat them as extreme values. This is good
14233 enough for windows, which can't have more than INT_MAX lines anyway.
14235 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14237 * Require libxml/parser.h to avoid compilation warning.
14239 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14241 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14242 since this reportedly can destroy thread storage.
14244 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14246 * syntax.c (find_defun_start): Update all cache variables if
14247 exiting early (Bug#9401).
14249 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14251 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14253 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14254 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14255 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14257 * term.c (tty_append_glyph): New function.
14258 (produce_stretch_glyph): Static function and its prototype deleted.
14260 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14263 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14265 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14266 when checking :margin (Bug#9390).
14267 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14268 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14269 so that the name doesn't mislead. All uses changed.
14271 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14273 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14276 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14278 * xdisp.c (move_it_to): Don't bail out early when reaching
14279 position beyond to_charpos, if we are scanning backwards.
14280 (move_it_vertically_backward): When DY == 0, make sure we get to
14281 the first character in the line after the newline.
14283 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14285 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14286 (ccl_driver): Do not generate an out-of-range pointer.
14287 (Fccl_execute_on_string): Remove unnecessary check for
14288 integer overflow, noted by Stefan Monnier in
14289 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14290 Remove a FIXME that didn't need fixing.
14291 Simplify the newly-introduced buffer reallocation code.
14293 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14295 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14297 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14299 Integer and memory overflow issues (Bug#9196).
14301 * doc.c (get_doc_string): Rework so that
14302 get_doc_string_buffer_size is the actual buffer size, rather than
14303 being 1 less than the actual buffer size; this makes xpalloc more
14306 * image.c (x_allocate_bitmap_record, cache_image):
14307 * xselect.c (Fx_register_dnd_atom):
14308 Simplify previous changes by using xpalloc.
14310 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14311 since either will do and ptrdiff_t is convenient with xpalloc.
14313 * charset.c (charset_table_size)
14314 (struct charset_sort_data.priority): Now ptrdiff_t.
14315 (charset_compare): Don't overflow if priorities differ greatly.
14316 (Fsort_charsets): Don't assume list length fits in int.
14317 Check for size-calculation overflow when allocating sort data.
14318 (syms_of_charset): Allocate an initial charset table that is
14319 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14321 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14323 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14324 The actual value is always <= INT_MAX, and leaving it unsigned made
14325 overflow checking harder.
14327 * dispextern.h (struct glyph_matrix.rows_allocated)
14328 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14329 with xpalloc. The values are still always <= INT_MAX.
14331 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14333 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14334 (SAFE_NALLOCA): New macro.
14336 * region-cache.c (struct boundary.pos, find_cache_boundary)
14337 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14338 (set_cache_region, invalidate_region_cache)
14339 (revalidate_region_cache, know_region_cache, region_cache_forward)
14340 (region_cache_backward, pp_cache):
14341 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14342 so that ptrdiff_t * can be passed to xpalloc.
14343 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14344 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14345 (pp_cache): Don't assume cache_len fits in int.
14346 * region-cache.h: Adjust extern decls to match.
14348 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14349 EMACS_INT, since either will do, for xpalloc.
14351 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14352 (xnmalloc, xnrealloc, xpalloc): New functions.
14354 * bidi.c (bidi_shelve_header_size): New constant.
14355 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14356 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14358 * bidi.c (bidi_cache_shrink):
14359 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14361 Don't update size of array until after memory allocation succeeds,
14362 because xmalloc/xrealloc may not return.
14363 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14364 now that we have proper integer overflow checking.
14365 (record_overlay_string, overlay_strings): Catch overflows when
14366 calculating size of overlay_str_buf.
14368 * callproc.c (Fcall_process): Check for size overflow when
14369 calculating size of args2.
14370 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14371 Normally we prefer signed values, but sticking with ptrdiff_t would
14372 require adding more-complicated checks.
14374 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14375 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14376 Redo buffer-overflow calculations to avoid integer overflow.
14377 Add a FIXME comment where memory seems to be over-allocated.
14379 * character.c (Fstring): Check for size-calculation overflow.
14381 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14382 unnecessary integer overflow. Check for size overflow.
14383 (encode_coding_object): Don't update size until xmalloc succeeds.
14385 * composite.c (get_composition_id): Check for overflow in glyph
14386 length calculations.
14388 Integer and memory overflow fixes for display code.
14389 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14390 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14391 (scrolling_window): Check for overflow in size calculations.

14398 * fns.c (concat): Check for overflow in size calculations.
14399 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14400 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

14403 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14404 (get_doc_string): Check for size calculation overflow.
14405 Don't update size until allocation succeeds.
14406 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14407 EMACS_INT, where ptrdiff_t will do.
14408 (Fsubstitute_command_keys): Check for string overflow.
14410 * editfns.c (set_time_zone_rule): Don't assume environment length
14412 (message_length): Now ptrdiff_t, not int.
14413 (Fmessage_box): Don't update size until allocation succeeds.
14414 Don't assume message length fits in int.
14415 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14417 * emacs.c (main): Do not reallocate argv, since there is a null at
14418 the end that can be overwritten, and this way there's no need to
14419 worry about size-calculation overflow.
14420 (sort_args): Check for size-calculation overflow.
14422 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14424 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14426 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14427 (x_set_scroll_bar_width, x_figure_window_size):
14428 Check for integer overflow.
14429 (x_set_alpha): Do not assume XINT fits in int.
14431 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14432 This is for the members text_lines, text_cols, total_lines, total_cols,
14433 where the system imposes an 'int' limit.
14435 * fringe.c (Fdefine_fringe_bitmap):
14436 Don't update size until alloc works.
14438 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14439 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14441 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14442 Check for size-calculation overflow.
14443 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14444 do, as we prefer signed integers.
14445 (id_to_widget.max_size, id_to_widget.used)
14446 (xg_store_widget_in_map, xg_remove_widget_from_map)
14447 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14448 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14449 Use and return ptrdiff_t, not int.
14450 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14451 * gtkutil.h: Change prototypes to match the above.
14453 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14454 are duplicate now that they've been promoted to lisp.h.
14455 (x_allocate_bitmap_record, x_alloc_image_color)
14456 (make_image_cache, cache_image, xpm_load):
14457 Don't update size until alloc is done.

14468 Use ptrdiff_t, not int, to count maps.
14469 (read_char_minibuf_menu_prompt): Check for overflow in size
14470 calculations. Don't update size until allocation succeeds.
14471 Redo calculations to avoid overflow.
14472 * keyboard.h: Change prototypes to match the above.
14474 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
14476 (current_minor_maps): Check for size calculation overflow.
14477 * keymap.h: Change prototypes to match the above.
14479 * lread.c (read1, init_obarray): Don't update size until alloc done.
14481 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

14500 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14501 for command line length. Do not attempt to address one before the
14502 beginning of an array, as that's not portable.
14504 * term.c (max_frame_lines): Remove; unused.
14505 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14507 (encode_terminal_code, calculate_costs): Check for size
14508 calculation overflow.

14514 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14515 subtracting pointers.
14516 (gobble_line): Check for overflow more carefully. Don't update size
14519 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
14520 Don't update size until alloc done.

14530 Use ptrdiff_t, not int, for sizes.
14531 (Finternal_make_lisp_face, cache_face):
14532 Check for size calculation overflow.
14533 (cache_face): Treat size calculation overflows as if they were
14534 memory exhaustion (the usual treatment), rather than aborting.
14536 * xfns.c (x_encode_text, x_set_name_internal)
14537 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14538 sizes, since they can exceed INT_MAX in size. Check for size

14542 (xg_select): Check for size calculation overflow.
14543 Don't update size until alloc done.
14545 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14546 as sprintf is limited to int lengths.
14548 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14549 (X_LONG_MIN): New macros.
14550 Use them to make the following changes clearer.
14551 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14552 This change doesn't affect the value now, but it may help remind
14553 future maintainers not to raise the value too much later.
14554 (SELECTION_QUANTUM): Remove, replacing with ...
14555 (selection_quantum): ... new function, which avoids overflow.
14557 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14558 assumption that selection length fits in 'int'.
14559 (x_reply_selection_request, x_handle_selection_request)
14560 (x_get_window_property, receive_incremental_selection)
14561 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
14562 (lisp_data_to_selection_data, clean_local_selection_data):
14563 Use ptrdiff_t, not int, to record length of selection.
14564 (x_reply_selection_request, x_get_window_property)

14566 Redo calculations to avoid overflow.
14567 (x_reply_selection_request): When sending hint, ceiling it at
14568 X_LONG_MAX rather than relying on wraparound overflow to send
14570 (x_get_window_property, receive_incremental_selection)
14571 (lisp_data_to_selection_data, x_property_data_to_lisp):
14572 Check for size-calculation overflow.
14573 (x_get_window_property, receive_incremental_selection)
14574 (lisp_data_to_selection_data, Fx_register_dnd_atom):
14575 Don't store size until memory allocation succeeds.
14576 (x_get_window_property): Plug memory leak on memory exhaustion.
14577 Don't double-block input; malloc is safe here. Don't assume 2**34
14578 - 4 fits in unsigned long. Add an xassert to check
14579 XGetWindowProperty overflow. Be more careful about overflow
14580 calculations, and distinguish size from memory overflow better.
14581 (receive_incremental_selection): When tracing, don't assume
14582 unsigned int is less than INT_MAX.
14583 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14584 harmful) conversions of unsigned short to int.
14585 (lisp_data_to_selection_data): Don't assume that integers
14586 in the range -65535 through -1 fit in an X unsigned short.
14587 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14588 result parameters unless successful. Rely on cons_to_unsigned
14589 to report problems with elements; the old code wasn't right anyway.
14590 (x_check_property_data): Check for int overflow; we cannot use
14591 a wider type due to X limits.
14592 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
14594 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
14596 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
14597 (x_term_init): Check for size calculation overflow.
14598 (x_color_cells): Don't store size until memory allocation succeeds.
14599 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
14600 Don't assume alloca size is less than MAX_ALLOCA.

14624 * lisp.h (hash_lookup, hash_put):
14625 * minibuf.c (Ftest_completion):
14626 Use ptrdiff_t for hash table indexes, not int (which is too
14627 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14628 32-bit --with-wide-int hosts).
14630 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14631 Add a FIXME comment about memory leaks.
14632 (syms_of_charset): Don't assume xmalloc returns.
14634 Don't assume that stated character widths fit in int.
14635 * character.c (Fchar_width, c_string_width, lisp_string_width):
14636 * character.h (CHAR_WIDTH):
14637 * indent.c (MULTIBYTE_BYTES_WIDTH):
14638 Use sanitize_char_width to avoid undefined and/or bad behavior
14639 with outlandish widths.
14640 * character.h (sanitize_tab_width): Rename from sanitize_width,
14641 now that we have two such functions. All uses changed.
14642 (sanitize_char_width): New inline function.
14644 Don't assume that tab-width fits in int.
14645 * character.h (sanitize_width): New inline function.
14646 (SANE_TAB_WIDTH): New macro.
14647 (ASCII_CHAR_WIDTH): Use it.

14652 * fileio.c: Integer overflow issues with file modes.
14653 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
14655 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

14660 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14661 (x_send_scroll_bar_event): Likewise. Check that the size does not
14662 exceed limits imposed by XClientMessageEvent, as well as the usual
14663 ptrdiff_t and size_t limits.
14665 * keyboard.c: Overflow, signedness and related fixes.
14666 (make_lispy_movement): Use same integer type in forward decl
14667 that is used in the definition.
14668 (read_key_sequence, keyremap_step):
14669 Change bufsize argument back to int, undoing my 2011-03-30 change.
14670 We prefer signed types, and int is wide enough here.
14671 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14672 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14673 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14674 length, not size_t. Use ptrdiff_t for index, not int.
14675 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14676 possibility of integer overflow.
14678 Overflow, signedness and related fixes for images.
14680 * dispextern.h (struct it.stack[0].u.image.image_id)
14681 (struct_it.image_id, struct image.id, struct image_cache.size)

14688 * xdisp.c (calc_pixel_width_or_height):
14689 * xfns.c (image_cache_refcount):
14690 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
14691 on typical 64-bit hosts.

14699 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
14700 (lookup_image): Remove unnecessary tests.
14701 (xbm_image_p): Locals are now of int, not EMACS_INT,
14702 since parse_image_check makes sure they fit into int.
14703 (png_load, gif_load, svg_load_image):
14704 Prefer int to unsigned where either will do.
14705 (tiff_handler): New function, combining the cores of the
14706 old tiff_error_handler and tiff_warning_handler.
14707 This function is rewritten to use vsnprintf and thereby avoid
14708 stack buffer overflows. It uses only the features of vsnprintf
14709 that are common to both POSIX and native Microsoft.
14710 (tiff_error_handler, tiff_warning_handler): Use it.
14711 (tiff_load, gif_load, imagemagick_load_image):
14712 Don't assume :index value fits in 'int'.
14713 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14714 (imagemagick_load_image): Check that crop parameters fit into
14715 the integer types that MagickCropImage accepts. Don't assume
14716 Vimagemagick_render_type has a nonnegative value. Don't assume
14717 size_t fits in 'long'.
14718 (gs_load): Use printmax_t to print the widest integers possible.
14719 Check for integer overflow when computing image height and width.
14721 2011-08-26 Eli Zaretskii <eliz@gnu.org>

14732 (handle_single_display_spec): If the display spec is of the form
14733 `(space ...)', and specifies display in the text area, return 2
14735 (try_cursor_movement): Check for the need to scroll more
14736 accurately, and prefer exact match for point under bidi.
14737 Don't advance `row' beyond the last row of the window.

14758 positioning on the newline at EOL of R2L text within L2R
14759 paragraph, and vice versa.
14760 (try_cursor_movement): Check continued rows, in addition to
14761 continuation rows. Fixes unwarranted scroll when point enters a
14762 continued line of R2L text within an L2R paragraph, or vice versa.

14790 * xdisp.c (redisplay_window): When computing centering_position,
14791 account for the height of the header line. (Bug#8874)
14793 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14794 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14795 candidate is selected by the mouse, and that candidate has a
14796 composed character under the mouse.
14798 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14799 coordinates reported by pos-visible-in-window-p for a composed
14800 character in column zero.
14802 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

14809 consider it a hit if to_charpos is anywhere in the range of the
14810 composed buffer positions.
14812 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14814 * image.c (gif_load): Don't assume that each subimage has the same
14815 dimensions as the base image. Handle disposal method that is
14816 "undefined" by the gif spec (Bug#9335).
14818 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14820 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14826 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14827 from an Org mode buffer to a Speedbar frame.
14829 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14830 a composition, take its buffer position from IT->cmp_it.charpos.
14831 Fixes cursor positioning at the beginning of a line that begins
14832 with a composed character.
14834 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14836 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14837 character bidirectional type, use STRONG_L instead. Fixes crashes
14838 in a buffer produced by `describe-categories'.
14840 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14841 members before the level stack, so they would be saved and
14842 restored when copying iterator state. Fixes incorrect reordering
14843 around TABs covered by display properties.

14933 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14934 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14935 the event loop (Bug#7276).

14979 the iterator structure wrt the object coming from a display
14980 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14981 properties. (Bug#9284)

15201 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15202 In other words, assume that every image size is allowed, on non-X
15203 hosts. This assumption is probably wrong, but it lets Emacs compile.
15205 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15207 * regex.c (re_iswctype): Convert return values to boolean.
15209 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15211 * xdisp.c (compute_display_string_pos): Don't use cached display
15212 string position if the buffer had its restriction changed.
15215 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15217 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15219 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15221 Integer signedness and overflow and related fixes. (Bug#9079)
15223 * bidi.c: Integer size and overflow fixes.
15224 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15225 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15226 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15227 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15228 (bidi_find_other_level_edge):
15229 Use ptrdiff_t instead of EMACS_INT where either will do.
15230 This works better on 32-bit hosts configured --with-wide-int.
15231 (bidi_cache_ensure_space): Check for size-calculation overflow.
15232 Use % rather than repeated addition, for better worst-case speed.
15233 Don't set bidi_cache_size until after xrealloc returns, because it
15235 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15236 (bidi_cache_ensure_space): Also check that the bidi cache size
15237 does not exceed that of the largest Lisp string or buffer. See Eli
15238 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15240 * alloc.c (__malloc_size_t): Remove.
15241 All uses replaced by size_t. See Andreas Schwab's note
15242 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15244 * image.c: Improve checking for integer overflow.
15245 (check_image_size): Assume that f is nonnull, since
15246 it is always nonnull in practice. This is one less thing to
15247 worry about when checking for integer overflow later.
15248 (x_check_image_size): New function, which checks for integer
15249 overflow issues inside X.
15250 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15251 This removes the need for a memory_full check.
15252 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15253 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15254 (xbm_read_bitmap_data): Change locals back to 'int', since
15255 their values must fit in 'int'.
15256 (xpm_load_image, png_load, tiff_load):
15257 Invoke x_create_x_image_and_pixmap earlier,
15258 to avoid much needless work if the image is too large.
15259 (tiff_load): Treat overly large images as if
15260 x_create_x_image_and_pixmap failed, not as malloc failures.
15261 (gs_load): Use x_check_image_size.
15263 * gtkutil.c: Omit integer casts.
15264 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15265 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15267 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15269 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15270 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15271 would wrongly return t on a 64-bit host.
15273 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15274 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15275 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15276 and therefore cause GCC to emit a bogus diagnostic in some cases.
15278 * image.c: Integer signedness and overflow and related fixes.
15279 This is not an exhaustive set of fixes, but it's time to
15280 record what I've got.
15281 (lookup_pixel_color, check_image_size): Remove redundant decls.
15282 (check_image_size): Don't assume that arbitrary EMACS_INT values
15283 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15284 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15285 (tiff_load, imagemagick_load_image):
15286 Check for overflow in size calculations.
15287 (x_create_x_image_and_pixmap): Remove unnecessary test for
15288 xmalloc returning NULL; that can't happen.
15289 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15290 (xpm_color_bucket): Use better integer hashing function.
15291 (xpm_cache_color): Don't possibly over-allocate memory.
15292 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15293 (gif_memory_source):
15294 Use ptrdiff_t, not int or size_t, to record sizes.
15295 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15296 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15297 either works, as we prefer signed integers.
15298 (tiff_read_from_memory, tiff_write_from_memory):
15299 Return tsize_t, not size_t, since that's what the TIFF API wants.
15300 (tiff_read_from_memory): Don't fail simply because the read would
15301 go past EOF; instead, return a short read.
15302 (tiff_load): Omit no-longer-needed casts.
15303 (Fimagemagick_types): Don't assume size fits into 'int'.
15305 Improve hashing quality when configured --with-wide-int.
15306 * fns.c (hash_string): New function, taken from sxhash_string.
15307 Do not discard information about ASCII character case; this
15308 discarding is no longer needed.
15309 (sxhash-string): Use it. Change sig to match it. Caller changed.
15310 * lisp.h: Declare it.
15311 * lread.c (hash_string): Remove, since we now use fns.c's version.
15312 The fns.c version returns a wider integer if --with-wide-int is
15313 specified, so this should help the quality of the hashing a bit.
15315 * emacs.c: Integer overflow minor fix.
15316 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15317 Define only if GNU_LINUX.
15318 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15320 * dispnew.c: Integer signedness and overflow fixes.
15321 Remove unnecessary forward decls, that were a maintenance hassle.
15322 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15324 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15325 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15326 (prepare_desired_row, line_draw_cost):
15327 Use int, not unsigned, where either works.
15328 (save_current_matrix, restore_current_matrix):
15329 Use ptrdiff_t, not size_t, where either works.
15330 (init_display): Check for overflow more accurately, and without
15331 relying on undefined behavior.
15333 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15334 Remove, replacing with the new symbols in lisp.h. All uses changed.
15335 * fileio.c (make_temp_name):
15336 * filelock.c (lock_file_1, lock_file):
15337 * xdisp.c (message_dolog):
15338 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15339 Use pMd etc. instead.
15340 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15341 replacing the pWIDE etc. symbols removed from editfns.c.
15343 * keyboard.h (num_input_events): Now uintmax_t.
15344 This is (very slightly) less likely to mess up due to wraparound.
15347 * buffer.c: Integer signedness fixes.
15348 (alloc_buffer_text, enlarge_buffer_text):
15349 Use ptrdiff_t rather than size_t when either will do, as we prefer
15352 * alloc.c: Integer signedness and overflow fixes.
15353 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15354 (__malloc_size_t): Default to size_t, not to int.
15355 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15356 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15357 Prefer ptrdiff_t to size_t when either would do, as we prefer
15359 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15360 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15361 Now const. Initialize with values that are in range even if char
15363 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15364 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15365 These functions do the right thing with sizes > 2**32.
15366 (check_depth): Now ptrdiff_t, not int.
15367 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15368 Adjust to new way of storing sizes. Check for size overflow bugs
15370 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15371 slightly wrong anyway, as it missed one instance of
15372 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15373 (refill_memory_reserve): Omit needless cast to size_t.
15374 (mark_object_loop_halt): Mark as externally visible.
15376 * xselect.c: Integer signedness and overflow fixes.
15377 (Fx_register_dnd_atom, x_handle_dnd_message):
15378 Use ptrdiff_t, not size_t, since we prefer signed.
15379 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15380 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15381 x_dnd_atoms_size and x_dnd_atoms_length.
15383 * doprnt.c: Prefer signed to unsigned when either works.
15385 * doprnt.c (doprnt):
15387 * xdisp.c (vmessage):
15388 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15389 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15390 prefer signed arithmetic to avoid comparison confusion.
15391 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15392 but is a bit tricky.
15394 Assume freestanding C89 headers, string.h, stdlib.h.
15395 * data.c, doprnt.c, floatfns.c, print.c:
15396 Include float.h unconditionally.
15397 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15398 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15399 * regex.c: Likewise for stddef.h, string.h.
15400 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15401 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15402 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15403 (STDC_HEADERS): Remove obsolete defines.
15404 * sysdep.c: Include limits.h unconditionally.
15406 Assume support for memcmp, memcpy, memmove, memset.
15407 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15408 * regex.c (memcmp, memcpy):
15409 Remove; we assume C89 now.
15411 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15412 (__malloc_safe_bcopy): Remove; no longer needed.
15414 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15415 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15416 well either way, and we prefer signed to unsigned.
15418 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15420 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15421 closes the connection while we're reading (bug#9182).
15423 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15425 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15426 are specified (Bug#9168).
15428 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15430 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15431 Found by GCC static checking and --with-wide-int on a 32-bit host.
15433 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15435 * xdisp.c (compute_display_string_pos): Fix logic of caching
15436 previous display string position. Initialize cached_prev_pos to
15437 -1. Fixes slow-down at the beginning of a buffer.
15439 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15441 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15442 for attrs[LFACE_FONTSET_INDEX].
15444 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15446 * xml.c (parse_region): Remove unused local
15447 that was recently introduced.
15449 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15451 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15452 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15454 * xdisp.c (move_it_in_display_line_to): Record the best matching
15455 position for TO_CHARPOS while scanning the line, and restore it on
15456 exit if none of the characters scanned was an exact match.
15457 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15458 when exact match is impossible due to invisible text, and the
15459 lines are truncated.
15461 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15463 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15466 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15468 Fix a significant slow-down of cursor motion with C-n, C-p,
15469 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15470 auto-repeat under bidi redisplay in fontified buffers.
15471 * xdisp.c (compute_stop_pos_backwards): New function.
15472 (next_element_from_buffer): Call compute_stop_pos_backwards to
15473 find a suitable prev_stop when we find ourselves before
15475 (reseat): Don't look for prev_stop, as that could mean a very long
15477 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15478 <cached_disp_overlay_modiff>: Cache for last found display string
15480 (compute_display_string_pos): Return the cached position if asked
15481 about the same buffer in the same area of character positions, and
15482 the buffer wasn't changed since the time the display string
15483 position was cached.
15485 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15487 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15488 is an integer, which is important for empty lines. (Bug#9149)
15490 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15492 * frame.c (Fmodify_frame_parameters): In tty case, update the
15493 default face if necessary (Bug#4238).
15495 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15497 * editfns.c (Fstring_to_char): No need to explain what a character
15498 is in the docstring (Bug#6576).
15500 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15502 * xml.c (parse_region): Make sure we always return a tree.
15504 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15506 * xml.c (parse_region): If a document contains only comments,
15509 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15511 * xml.c (make_dom): Return comments, too.
15513 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15516 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15517 and the surrounding thread.
15518 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15519 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15520 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15522 * s/openbsd.h (BROKEN_SIGIO): Define.
15523 * unexelf.c (unexec) [__OpenBSD__]:
15524 Don't update the .mdebug section of the Alpha COFF symbol table.
15526 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15528 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15531 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15533 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15534 This fixes some race conditions on the permissions of any newly
15537 * alloc.c (valid_pointer_p): Use pipe, not open.
15538 This fixes some permissions issues when debugging.
15540 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15541 If fchown fails to set both uid and gid, try to set just gid,
15542 as that is sometimes allowed. Adjust the file's mode to eliminate
15543 setuid or setgid bits that are inappropriate if fchown fails.
15545 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15547 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15548 to compare Lisp_Objects.
15549 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15550 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15551 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15553 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15555 * lread.c (read_integer): Unread even EOF character.
15556 (read1): Likewise. Properly record start position of symbol.
15558 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15559 symbol character follows.
15561 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15563 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15564 This works around a problem with the previous change to Fcopy_file.
15565 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15566 and without this change, GCC might complain about discarding
15567 fchown's return value.
15569 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15571 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15573 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15575 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15577 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15579 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15580 it's used from the C level.
15582 * process.c: Use the same condition for POLL_FOR_INPUT in both
15583 keyboard.c and process.c (bug#1858).
15585 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15587 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15588 (Fgnutls_boot): Use it.
15590 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15592 * doc.c (Fsubstitute_command_keys): Revert last change.
15594 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15596 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15597 quotes the next character, and doesn't affect other longer
15598 sequences (bug#8935).
15600 * lread.c (syms_of_lread): Clarify that is isn't only
15601 `eval-buffer' and `eval-defun' that's affected by
15602 `lexical-binding' (bug#8460).
15604 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15606 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15607 bidi redisplay when a line includes both an image and is truncated.
15609 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15611 Fix minor problems found by static checking.
15612 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15613 (elsz): Now a signed constant, not a size_t var. We prefer signed
15614 types to unsigned, to avoid integer comparison confusion. Without
15615 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15616 "cannot optimize loop, the loop counter may overflow", a symptom
15618 * indent.c (Fvertical_motion): Mark locals as initialized.
15619 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15621 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15623 * search.c (Fre_search_backward): Mention `case-fold-search' in
15624 all the re_search_* functions (bug#8138).
15626 * keyboard.c (Fopen_dribble_file): Document when the file is
15629 2011-07-14 Eli Zaretskii <eliz@gnu.org>
15631 * bidi.c (bidi_dump_cached_states): Fix format of displaying
15634 Support bidi reordering of display and overlay strings.
15635 * xdisp.c (compute_display_string_pos)
15636 (compute_display_string_end): Accept additional argument STRING.
15637 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15638 (reseat_to_string): Initialize bidi_it->string.s and
15639 bidi_it->string.schars.
15640 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15641 NULL (avoids a crash in bidi_paragraph_init).
15642 Initialize itb.string.lstring.

16141 * alloc.c (mark_buffer):
16142 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
16143 (clone_per_buffer_values): Don't assume that
16144 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
16145 This isn't true in general, and it's particularly not true
16146 if Emacs is configured with --with-wide-int.
16147 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16148 New macros, used in the buffer.c change.

16182 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
16184 Random fixes. E.g., (random) never returned negative values.
16185 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16186 subseconds part to the entropy, as that's a bit more random.
16187 Prefer signed to unsigned, since the signedness doesn't matter and
16188 in general we prefer signed. When given a limit, use a
16189 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16190 latter isn't right if USE_2_TAGS_FOR_INTS.
16191 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16192 not 0..VALMASK. Don't discard "excess" bits that random () returns.
16194 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
16196 * textprop.c (text_property_stickiness):
16197 Obey Vtext_property_default_nonsticky.

16204 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16205 This is more efficient than Ffile_directory_p and avoids a minor race.
16207 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16209 * buffer.c (Foverlay_put): Say what the return value is
16212 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16213 is a directory before asking whether to use the file name
16215 (barf_or_query_if_file_exists): Make the "File is a directory"
16216 error be more correct.
16218 * fns.c (Frequire): Remove the mention of the .gz files, since
16219 that's installation-specific, but keep the mention of
16220 `get-load-suffixes'.
16222 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
16224 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

16230 (syms_of_gnutls): Remove duplicate DEFSYM for
16231 Qgnutls_bootprop_verify_hostname_error, an error for
16232 Qgnutls_bootprop_verify_error (which is no longer used).
16234 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16235 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16236 Also (re)move comments that are misplaced or no longer relevant.
16238 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16240 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
16242 2011-07-03 Chong Yidong <cyd@stupidchicken.com>
16244 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
16245 and background color parameters if they have been changed.

16299 (syms_of_keymap): Defsubr make-composed-keymap.
16300 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16337 * eval.c (struct backtrace): Simplify and port the data structure.
16338 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16339 signed bit field, as this assumption is not portable and it makes
16340 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16341 "char debug_on_exit : 1" as this is not portable either; instead,
16342 use the portable "unsigned int debug_on_exit : 1". Remove unused
16343 member evalargs. Remove obsolete comments about cc bombing out.
16345 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16520 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16521 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
16522 Use ptrdiff_t, not int, for sizes.
16523 Don't increment bufsize until after realloc succeeds.
16524 Check for size-calculation overflow.
16525 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16527 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16529 * lread.c: Integer overflow fixes.
16530 (read_integer): Radix is now EMACS_INT, not int,
16531 to improve quality of diagnostics for out-of-range radices.
16532 Calculate buffer size correctly for out-of-range radices.
16533 (read1): Check for integer overflow in radices, and in
16534 read-circle numbers.
16535 (read_escape): Avoid int overflow.
16536 (Fload, openp, read_buffer_size, read1)
16537 (substitute_object_recurse, read_vector, read_list, map_obarray):
16538 Use ptrdiff_t, not int, for sizes.
16539 (read1): Use EMACS_INT, not int, for sizes.

16551 (read_escape): Check for hex character overflow.
16553 2011-06-22 Leo Liu <sdl.web@gmail.com>
16555 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16556 Move to minibuffer.el.
16558 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16560 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16561 The following patches are for when GLYPH_DEBUG && !XASSERT.
16562 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16563 * dispnew.c (flush_stdout):
16564 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16565 Mark as externally visible.
16566 * dispnew.c (check_window_matrix_pointers): Now static.
16567 * dispnew.c (window_to_frame_vpos):
16568 * xfns.c (unwind_create_frame):
16569 * xterm.c (x_check_font): Remove unused local.
16570 * scroll.c (CHECK_BOUNDS):
16571 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16572 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16573 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16574 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16575 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16577 (debug_method_add): Use va_list and vsprintf rather than relying
16578 on undefined behavior with wrong number of arguments.
16579 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16580 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16581 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16582 since we're not interested in debugging glyphs with old libraries.
16583 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16584 GCC 4.6.0's static checking.
16586 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16588 Integer overflow and signedness fixes (Bug#8873).

16597 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16598 (x_create_bitmap_from_xpm_data):
16599 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16600 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16602 * xfaces.c (load_pixmap):
16603 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16604 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16605 (.bitmaps_last, struct x_output.icon_bitmap):
16606 Use ptrdiff_t, not int, for bitmap indexes.
16607 (x_allocate_bitmap_record): Check for size overflow.
16608 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16610 Use ptrdiff_t, not int, for overlay counts.
16611 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16612 * editfns.c (overlays_around, get_pos_property):
16613 * textprop.c (get_char_property_and_overlay):
16614 * xdisp.c (next_overlay_change, note_mouse_highlight):
16615 * xfaces.c (face_at_buffer_position):
16616 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16617 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16618 (Fnext_overlay_change, Fprevious_overlay_change)
16619 (mouse_face_overlay_overlaps, Foverlays_in):
16620 Use ptrdiff_t, not int, for sizes.
16621 (overlays_at, overlays_in): Check for size-calculation overflow.
16623 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16625 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16626 (x_session_initialize): Do not assume string length fits in int.
16628 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16629 This is unlikely, but can occur if DPI is outlandish.
16631 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16632 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16634 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16635 * xrdb.c (magic_file_p, search_magic_path):
16636 Omit last arg SUFFIX; it was always 0. All callers changed.
16637 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16639 * xfont.c (xfont_match): Avoid need for strlen.
16641 * xfns.c: Don't assume strlen fits in int.
16642 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16644 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16645 not unsigned long, as we prefer signed integers. All callers changed.
16646 Detect integer overflow in repeat count.
16647 (message_dolog): Don't assume print length fits in 39 bytes.
16648 (display_mode_element): Don't assume strlen fits in int.
16650 * termcap.c: Don't assume sizes fit in int and never overflow.
16651 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16652 (gobble_line): Check for size-calculation overflow.
16654 * minibuf.c (Fread_buffer):
16655 * lread.c (intern, intern_c_string):
16656 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16657 Don't assume string length fits in int.
16659 * keyboard.c (parse_tool_bar_item):
16660 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16662 * font.c: Don't assume string length fits in int.
16663 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16664 Use ptrdiff_t, not int.
16665 (font_intern_prop): Don't assume string length fits in int.
16666 Don't assume integer property fits in fixnum.
16667 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16669 * filelock.c: Fix some buffer overrun and integer overflow issues.
16670 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16671 Reformulate so as not to need the command string.
16672 Invoke gzip -cd rather than gunzip, as it's more portable.
16673 (lock_info_type, lock_file_1, lock_file):
16674 Don't assume pid_t and time_t fit in unsigned long.
16675 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16676 (current_lock_owner): Prefer signed type for sizes.
16677 Use memcpy, not strncpy, where memcpy is what is really wanted.
16678 Don't assume (via atoi) that time_t and pid_t fit in int.
16679 Check for time_t and/or pid_t out of range, e.g., via a network share.
16680 Don't alloca where an auto var works fine.
16682 * fileio.c: Fix some integer overflow issues.
16683 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16684 Don't assume string length fits in int.
16685 (directory_file_name): Don't assume string length fits in long.
16686 (make_temp_name): Don't assume pid fits in int, or that its print
16687 length is less than 20.
16689 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16691 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16693 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16695 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16696 We prefer signed integers, even for size calculations.
16698 * emacs.c: Don't assume string length fits in 'int'.
16699 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16700 (main): Don't invoke strlen when not needed.
16702 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16703 (XD_DEBUG_MESSAGE): Don't waste a byte.
16705 * callproc.c (getenv_internal_1, getenv_internal)
16706 (Fgetenv_internal):
16707 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16709 * lread.c (invalid_syntax): Omit length argument.
16710 All uses changed. This doesn't fix a bug, but it simplifies the
16711 code away from its former Hollerith-constant appearance, and it's
16712 one less 'int' to worry about when looking at integer-overflow issues.
16713 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16715 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16716 This didn't break anything, but it didn't help either.
16717 It's confusing to put a bogus integer in a place where the actual
16718 value does not matter.
16719 (LIST_END_P): Remove unused macro and its bogus comment.
16720 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16722 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16723 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16725 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16726 We prefer signed types, and the value cannot exceed the EMACS_INT
16727 range anyway (because otherwise the length would not be representable).
16728 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16729 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16730 This avoids a GCC warning when WIDE_EMACS_INT.
16732 * indent.c (sane_tab_width): New function.
16733 (current_column, scan_for_column, Findent_to, position_indentation)
16734 (compute_motion): Use it. This is just for clarity.
16735 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16737 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16739 * lisp.h (lint_assume): New macro.
16740 * composite.c (composition_gstring_put_cache):
16741 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16743 * editfns.c, insdel.c:
16744 Omit unnecessary forward decls, to simplify future changes.
16746 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16748 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16750 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16751 Use much-faster test for byte-length change.
16752 Don't assume string byte-length fits in 'int'.
16753 Check that character arg fits in 'int'.
16754 (mapcar1): Declare byte as byte, for clarity.
16756 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16758 * fns.c (concat): Catch string overflow earlier.
16759 Do not rely on integer wraparound.
16761 * dispextern.h (struct it.overlay_strings_charpos)
16762 (struct it.selective): Now EMACS_INT, not int.
16763 * xdisp.c (forward_to_next_line_start)
16764 (back_to_previous_visible_line_start)
16765 (reseat_at_next_visible_line_start, next_element_from_buffer):
16766 Don't arbitrarily truncate the value of 'selective' to int.
16768 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16770 * composite.c: Don't truncate sizes to 'int'.
16771 (composition_gstring_p, composition_reseat_it)
16772 (composition_adjust_point): Use EMACS_INT, not int.
16773 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16774 not EMACS_UINT, for indexes.
16776 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16778 * buffer.c: Include <verify.h>.
16779 (struct sortvec.priority, struct sortstr.priority):
16780 Now EMACS_INT, not int.
16781 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16782 (struct sortstr.size, record_overlay_string)
16783 (struct sortstrlist.size, struct sortlist.used):
16784 Don't truncate size to int.
16785 (record_overlay_string): Check for size-calculation overflow.
16786 (init_buffer_once): Check at compile-time, not run-time.
16788 2011-06-22 Jim Meyering <meyering@redhat.com>
16790 Don't leak an XBM-image-sized buffer
16791 * image.c (xbm_load): Free the image buffer after using it.
16793 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16796 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16797 that Sun C diagnosed.
16798 * fns.c (secure_hash): Fix pointer signedness issue.
16799 * intervals.c (static_offset_intervals): New function.
16800 (offset_intervals): Use it.
16802 2011-06-21 Leo Liu <sdl.web@gmail.com>
16805 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16808 * fns.c (secure_hash): Rename from crypto_hash_function and change
16809 the first arg to accept symbols.
16810 (Fsecure_hash): New primitive.
16811 (syms_of_fns): New symbols.
16813 2011-06-20 Deniz Dogan <deniz@dogan.se>
16815 * process.c (Fset_process_buffer): Clarify return value in
16818 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16820 * dispnew.c (add_window_display_history): Use BVAR.
16822 * xdisp.c (debug_method_add): Use BVAR.
16823 (check_window_end, dump_glyph_matrix, dump_glyph)
16824 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16826 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16829 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16830 check till after the cache is created in init_frame_faces.
16832 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16834 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16836 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16838 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16839 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16840 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16842 Improve buffer-overflow checking (Bug#8873).
16843 * fileio.c (Finsert_file_contents):
16844 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16845 Remove the old (too-loose) buffer overflow checks.
16846 They weren't needed, since make_gap checks for buffer overflow.
16847 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16848 The old code merely checked for Emacs fixnum overflow, and relied
16849 on undefined (wraparound) behavior. The new code avoids undefined
16850 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16852 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16853 Tune. Don't use wider integers than needed. Don't use alloca.
16854 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16856 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16858 * insdel.c, lisp.h (buffer_overflow): New function.
16859 (insert_from_buffer_1, replace_range, replace_range_2):
16860 * insdel.c (make_gap_larger):
16861 * editfns.c (Finsert_char):
16862 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16864 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16866 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16868 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16870 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16871 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16873 * fileio.c: Don't assume EMACS_INT fits in off_t.
16874 (emacs_lseek): New static function.
16875 (Finsert_file_contents, Fwrite_region): Use it.
16876 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16878 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16880 * fns.c: Don't overflow int when computing a list length.
16881 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16882 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16883 truncation on 64-bit hosts. Check for QUIT every
16884 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16885 faster and is responsive enough.
16886 (Flength): Report an error instead of overflowing an integer.
16887 (Fsafe_length): Return a float if the value is not representable
16888 as a fixnum. This shouldn't happen except in contrived situations.
16889 (Fnthcdr, Fsort): Don't assume list length fits in int.
16890 (Fcopy_sequence): Don't assume vector length fits in int.
16892 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16893 (header_size, word_size): New constants.
16894 (allocate_vectorlike): Don't check size overflow here.
16895 (allocate_vector): Check it here instead, since this is the only
16896 caller of allocate_vectorlike that could cause overflow.
16897 Check that the new vector's length is representable as a fixnum.
16899 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16900 The previous code was bogus. For example, next_almost_prime (32)
16901 returned 39, which is undesirable as it is a multiple of 3; and
16902 next_almost_prime (24) returned 25, which is a multiple of 5 so
16903 why was the code bothering to check for multiples of 7?
16905 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16907 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16909 Variadic C functions now count arguments with ptrdiff_t.
16910 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16911 Back then I didn't know that the Emacs coding style prefers signed int.
16912 Also, in the meantime I found a few more instances where arguments
16913 were being counted with int, which may truncate counts on 64-bit
16914 machines, or EMACS_INT, which may be unnecessarily wide.
16915 * lisp.h (struct Lisp_Subr.function.aMANY)
16916 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16917 Arg counts are now ptrdiff_t, not size_t.
16918 All variadic functions and their callers changed accordingly.
16919 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16920 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16921 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16922 * callint.c (Fcall_interactively): Check arg count for overflow,
16923 to avoid potential buffer overrun. Use signed char, not 'int',
16924 for 'varies' array, so that we needn't bother to check its size
16925 calculation for overflow.
16926 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16927 * eval.c (apply_lambda):
16928 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16929 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16930 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16932 * callint.c (Fcall_interactively): Don't use index var as event count.
16934 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16935 * mem-limits.h (SIZE): Remove; no longer used.
16937 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16939 Remove unnecessary casts.
16940 * xterm.c (x_term_init):
16941 * xfns.c (x_set_border_pixel):
16942 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16943 These aren't needed now that we assume ANSI C.
16945 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16946 It's more likely to cause problems (due to unsigned overflow)
16949 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16951 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16953 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16955 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16957 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16959 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16961 GLYPH_CODE_FACE returns EMACS_INT, not int.
16962 * dispextern.h (merge_faces):
16963 * xfaces.c (merge_faces):
16964 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16965 Don't assume EMACS_INT fits in int.
16967 * character.h (CHAR_VALID_P): Remove unused parameter.
16968 * fontset.c, lisp.h, xdisp.c: All uses changed.
16970 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16972 * fns.c (concat): Minor tuning based on overflow analysis.
16973 This doesn't fix any bugs. Use int to hold character, instead
16974 of constantly refetching from Emacs object. Use XFASTINT, not
16975 XINT, for value known to be a character. Don't bother comparing
16976 a single byte to 0400, as it's always less.
16978 * floatfns.c (Fexpt):
16979 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16981 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16984 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16986 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16987 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16988 incorrectly succeed when S was a string, because 4294967386 was
16989 truncated before it was used.
16991 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16992 Otherwise, an out-of-range integer could cause undefined behavior
16995 * composite.c: Use int, not EMACS_INT, for characters.
16996 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16997 EMACS_INT, for values that are known to be in character range.
16998 This doesn't fix any bugs but is the usual style inside Emacs and
16999 may generate better code on 32-bit machines.
17001 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17002 This is for reasons similar to the recent CHAR_STRING fix.
17003 * charset.c (Fencode_char): Check that character arg is actually
17004 a character. Pass an int to ENCODE_CHAR.
17005 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17006 wider than 'int', as a compile-time check to prevent future regressions
17009 * character.c (char_string): Remove unnecessary casts.
17011 Make sure a 64-bit char is never passed to CHAR_STRING.
17012 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17013 by silently ignoring the top 32 bits, allowing some values
17014 that were far too large to be valid characters.
17015 * character.h: Include <verify.h>.
17016 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17017 arguments are no wider than unsigned, as a compile-time check
17018 to prevent future regressions in this area.
17020 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17021 (Fsubst_char_in_region):
17023 * xdisp.c (decode_mode_spec_coding):
17024 Adjust to CHAR_STRING's new requirement.
17025 * editfns.c (Finsert_char, Fsubst_char_in_region):
17026 * fns.c (concat): Check that character args are actually
17027 characters. Without this test, these functions did the wrong
17028 thing with wildly out-of-range values on 64-bit hosts.
17030 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17031 These casts should not be needed on 32-bit hosts, either.
17032 * keyboard.c (read_char):
17033 * lread.c (Fload): Remove casts to unsigned.
17035 * lisp.h (UNSIGNED_CMP): New macro.
17036 This fixes comparison bugs on 64-bit hosts.
17037 (ASCII_CHAR_P): Use it.
17038 * casefiddle.c (casify_object):
17039 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17040 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17041 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17042 * dispextern.h (FACE_FROM_ID):
17043 * keyboard.c (read_char): Use UNSIGNED_CMP.
17045 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17046 not to EMACS_INT, to avoid GCC warning.
17048 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17050 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17051 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17052 isn't needed on 32-bit machines.
17054 * buffer.c (Fgenerate_new_buffer_name):
17055 Use EMACS_INT for count, not int.
17056 (advance_to_char_boundary): Return EMACS_INT, not int.
17058 * data.c (Qcompiled_function): Now static.
17060 * window.c (window_body_lines): Now static.
17062 * image.c (gif_load): Rename local to avoid shadowing.
17064 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17065 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17066 * alloc.c (make_save_value): Integer argument is now of type
17067 ptrdiff_t, not int.
17068 (mark_object): Use ptrdiff_t, not int.
17069 * lisp.h (pD): New macro.
17070 * print.c (print_object): Use it.
17072 * alloc.c: Use EMACS_INT, not int, to count objects.
17073 (total_conses, total_markers, total_symbols, total_vector_size)
17074 (total_free_conses, total_free_markers, total_free_symbols)
17075 (total_free_floats, total_floats, total_free_intervals)
17076 (total_intervals, total_strings, total_free_strings):
17077 Now EMACS_INT, not int. All uses changed.
17078 (Fgarbage_collect): Compute overall total using a double, so that
17079 integer overflow is less likely to be a problem. Check for overflow
17080 when converting back to an integer.
17081 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17082 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17083 These were 'int' variables that could overflow on 64-bit hosts;
17084 they were never used, so remove them instead of repairing them.
17085 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17086 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17087 Previously, this ceilinged at INT_MAX, but that doesn't work on
17089 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17091 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17092 (allocate_vectorlike): Check for ptrdiff_t overflow.
17093 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17094 when a (possibly-narrower) signed value would do just as well.
17095 We prefer using signed arithmetic, to avoid comparison confusion.
17097 * alloc.c: Catch some string size overflows that we were missing.
17098 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17099 for convenience in STRING_BYTES_MAX.
17100 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17101 The definition here is exact; the one in lisp.h was approximate.
17102 (allocate_string_data): Check for string overflow. This catches
17103 some instances we weren't catching before. Also, it catches
17104 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17105 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17106 and ptrdiff_t and EMACS_INT are both 64 bits.
17108 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17109 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17110 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17112 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17114 * alloc.c (Fmake_string): Check for out-of-range init.
17116 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17118 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17120 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17122 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

17133 and height if HAVE_GTK3 (Bug#8505).
17134 (scroll_bar_width_for_theme): New variable.
17135 (update_theme_scrollbar_width): New function.
17136 (xg_get_default_scrollbar_width): Move code to
17137 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

17140 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17142 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

17146 * frame.c (make_frame): Call other_buffer_safely instead of
17149 * window.c (temp_output_buffer_show): Call display_buffer with
17150 second argument Vtemp_buffer_show_specifiers and reset latter
17151 immediately after the call.
17152 (Vtemp_buffer_show_specifiers): New variable.
17153 (auto_window_vscroll_p, next_screen_context_lines)
17154 (Vscroll_preserve_screen_position): Remove leading asterisks from

17337 Remove static from declaration of Qdelete_window, it's
17338 temporarily needed by Fbury_buffer.
17339 (replace_window): Don't assign orig_top_line and

17718 value of a `display' property is a "replacing spec".
17719 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17720 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

17750 * gnutls.c: Use Emacs's memory allocators.
17751 Without this change, the gnutls library would invoke malloc etc.
17752 directly, which causes problems on non-SYNC_INPUT hosts, and which
17753 runs afoul of improving memory_full behavior. (Bug#8761)
17754 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17755 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17756 xfree instead of the default malloc, realloc, free.
17757 (Fgnutls_boot): No need to check for memory allocation failure,
17758 since xmalloc does that for us.

17782 * alloc.c (allocate_vectorlike):
17783 Check for overflow in vector size calculations.
17784 * ccl.c (ccl_driver):
17785 Check for overflow when converting EMACS_INT to int.

17787 need to be updated by these changes.
17788 * fns.c (make_hash_table, maybe_resize_hash_table):
17789 Check for integer overflow with large hash tables.
17790 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17791 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17792 (SXHASH_REDUCE): New macro.
17793 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17794 Use it instead of discarding useful hash info with large hash values.
17795 (sxhash_float): New function.
17796 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17797 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17798 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17799 Rewrite to use FIXNUM_BITS, as this simplifies things.
17800 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17801 Adjust signatures to match updated version of code.
17802 (consing_since_gc): Now EMACS_INT, since a single hash table can
17803 use more than INT_MAX bytes.

17818 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17819 Update dependencies.
17821 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17823 * data.c (init_data): Remove code for UTS, this system is not
17826 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17828 Don't force ./temacs to start in terminal mode.
17830 * frame.c (make_initial_frame): Initialize faces in all cases, not
17831 only when CANNOT_DUMP is defined.
17832 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17834 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17836 * dispnew.c (add_window_display_history): Use const for the string
17837 pointer. Remove declaration, not needed.
17839 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17841 Use 'inline', not 'INLINE'.
17842 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17843 * alloc.c, fontset.c (INLINE): Remove.
17844 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17845 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17846 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17847 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17848 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17850 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17852 Make it possible to run ./temacs.
17854 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17855 syms_of_callproc does the same thing. Remove test for
17856 "initialized", do it in the caller.
17857 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17859 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17861 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17862 (read_minibuf): Use get_minibuffer.
17863 (syms_of_minibuf): Use DEFSYM.
17864 (Qmetadata): New var.
17865 * data.c (Qbuffer): Don't make it static.
17866 (syms_of_data): Use DEFSYM.
17868 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17870 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17871 (CCL_CODE_MIN): New macro.
17873 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17875 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17877 * eval.c (Qdebug): Now static.
17878 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17879 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17880 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17882 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17884 * image.c: Various fixes to ImageMagick code comments.
17885 (Fimagemagick_types): Doc fix.
17887 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17889 Minor fixes prompted by GCC 4.6.0 warnings.
17891 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17893 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17894 (x_clipboard_manager_save_all): Move extern decl to ...
17895 * xterm.h: ... here, so that it can be checked for consistency.
17897 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17899 * xselect.c (x_clipboard_manager_save_frame)
17900 (x_clipboard_manager_save_all): New functions.
17901 (Fx_clipboard_manager_save): Lisp function deleted.
17903 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17904 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17906 * xterm.h: Update prototype.
17908 2011-05-28 William Xu <william.xwl@gmail.com>
17910 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17911 exiting (Bug#8239).
17913 2011-05-28 Jim Meyering <meyering@redhat.com>
17915 Avoid a sign-extension bug in crypto_hash_function.
17916 * fns.c (to_uchar): Define.
17917 (crypto_hash_function): Use it to convert some newly-signed
17918 variables to unsigned, to avoid sign-extension bugs. For example,
17919 without this change, (md5 "truc") would evaluate to
17920 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17921 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17922 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17924 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17926 Integer overflow fixes.
17928 * dbusbind.c: Serial number integer overflow fixes.
17929 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17930 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17931 to hold a serial number that is too large for a fixnum.
17932 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17933 Check for serial numbers out of range. Decode any serial number
17934 that was so large that it became a float. (Bug#8722)
17936 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17937 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17938 Use XFASTINT rather than XUINT when numbers are nonnegative.
17939 (xd_append_arg, Fdbus_method_return_internal):
17940 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17941 arguments, check that Lisp number is nonnegative, rather than
17942 silently wrapping negative numbers around. (Bug#8722)
17943 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17946 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17948 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17950 ccl: Add integer overflow checks.
17951 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17952 (IN_INT_RANGE): New macros.
17953 (ccl_driver): Use them to check for integer overflow when
17954 decoding a CCL program. Many of the new checks are whether XINT (x)
17955 fits in int; it doesn't always, on 64-bit hosts. The new version
17956 doesn't catch all possible integer overflows, but it's an
17957 improvement. (Bug#8719)
17959 * alloc.c (make_event_array): Use XINT, not XUINT.
17960 There's no need for unsigned here.
17962 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17963 This follows up to the 2011-05-06 change that substituted uintptr_t
17964 for EMACS_INT. This case wasn't caught back then.
17966 Rework Fformat to avoid integer overflow issues.
17967 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17968 now (part of C89). Include <verify.h>.
17969 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17970 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17971 (Fformat): Avoid the prepass trying to compute sizes; it was only
17972 approximate and thus did not catch overflow reliably. Instead, walk
17973 through the format just once, formatting and computing sizes as we go,
17974 checking for integer overflow at every step, and allocating a larger
17975 buffer as needed. Keep track separately whether the format is
17976 multibyte. Keep only the most-recently calculated precision, rather
17977 than them all. Record whether each argument has been converted to
17978 string. Use EMACS_INT, not int, for byte and char and arg counts.
17979 Support field widths and precisions larger than INT_MAX. Avoid
17980 sprintf's undefined behavior with conversion specifications such as %#d
17981 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17982 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17983 formatting out-of-range floating point numbers with int
17984 formats. (Bug#8668)
17986 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17988 * data.c: Avoid integer truncation in expressions involving floats.
17989 * data.c: Include <intprops.h>.
17990 (arith_driver): When there's an integer overflow in an expression
17991 involving floating point, convert the integers to floating point
17992 so that the resulting value does not suffer from catastrophic
17993 integer truncation. For example, on a 64-bit host (* 4
17994 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17995 Do not rely on undefined behavior after integer overflow.
17997 merge count_size_as_multibyte, parse_str_to_multibyte
17998 * character.c, character.h (count_size_as_multibyte):
17999 Rename from parse_str_to_multibyte; all uses changed.
18000 Check for integer overflow.
18001 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18002 since it's now a duplicate of the other. This is more of
18003 a character than a buffer op, so better that it's in character.c.
18004 * fns.c, print.c: Adjust to above changes.
18006 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18008 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18010 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18012 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18013 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18014 (x_clipboard_manager_save): Now static.
18015 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18017 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18018 (crypto_hash_function): Now static.
18019 Fix pointer signedness problems. Avoid unnecessary initializations.
18021 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18023 * termhooks.h (Vselection_alist): Make it terminal-local.
18025 * terminal.c (create_terminal): Initialize it.
18027 * xselect.c: Support for clipboard managers.
18028 (Vselection_alist): Move to termhooks.h as terminal-local var.
18029 (LOCAL_SELECTION): New macro.
18030 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18031 (symbol_to_x_atom): Remove gratuitous arg.
18032 (x_handle_selection_request, lisp_data_to_selection_data)
18033 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18034 (x_own_selection, x_get_local_selection, x_convert_selection):
18035 New arg, specifying work frame. Use terminal-local Vselection_alist.
18036 (some_frame_on_display): Delete unused function.
18037 (Fx_own_selection_internal, Fx_get_selection_internal)
18038 (Fx_disown_selection_internal, Fx_selection_owner_p)
18039 (Fx_selection_exists_p): New optional frame arg.
18040 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18041 (x_handle_selection_clear): Don't treat other terminals with the
18042 same keyboard specially. Use the terminal-local Vselection_alist.
18043 (x_clear_frame_selections): Use Frun_hook_with_args.
18045 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18047 * xterm.h: Add support for those atoms.
18049 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18051 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18052 (converted_selections, conversion_fail_tag): New global variables.
18053 (x_selection_request_lisp_error): Free the above.
18054 (x_get_local_selection): Remove unnecessary code.
18055 (x_reply_selection_request): Args changed; handle arbitrary array
18056 of converted selections stored in converted_selections.
18057 Separate the XChangeProperty and SelectionNotify steps.
18058 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18059 (x_convert_selection): New function.
18060 (x_handle_selection_event): Simplify.
18061 (x_get_foreign_selection): Don't ignore incoming requests while
18062 waiting for an answer; this will fail when we implement
18063 SAVE_TARGETS, and seems unnecessary anyway.
18064 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18065 (Vx_sent_selection_functions): Doc fix.
18067 2011-05-26 Leo Liu <sdl.web@gmail.com>
18069 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18071 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18073 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18075 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18076 for fringe update if it has periodic bitmap.
18077 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18078 and fringe_bitmap_periodic_p.
18080 * fringe.c (get_fringe_bitmap_data): New function.
18081 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18082 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18083 row. Mark glyph row for fringe update if periodicity changed.
18085 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18086 for fringe update unless it has periodic bitmap.
18088 2011-05-25 Kenichi Handa <handa@m17n.org>
18090 * xdisp.c (get_next_display_element): Set correct it->face_id for
18091 a static composition.
18093 2011-05-24 Leo Liu <sdl.web@gmail.com>
18096 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18098 * fns.c (crypto_hash_function, Fsha1): New function.
18099 (Fmd5): Use crypto_hash_function.
18100 (syms_of_fns): Add Ssha1.
18102 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18104 * gnutls.c: Remove unused macros.
18105 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18106 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18107 Remove macros that are defined and never used.
18108 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18110 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18112 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18113 (Fx_get_selection_internal): Minor cleanup.
18114 (Fx_own_selection_internal): Rename arguments for consistency with
18117 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18119 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18121 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18123 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18125 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18127 * dispnew.c (scrolling_window): Don't exclude the case that the
18128 last enabled row in the desired matrix touches the bottom boundary.
18130 2011-05-21 Glenn Morris <rgm@gnu.org>
18132 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18133 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18134 and add some more files.
18136 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18138 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18139 report_file_error introduced by the change from 2011-05-07.
18141 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18143 * systime.h (Time): Define only if emacs is defined.
18144 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18145 where the include path doesn't have X11/X.h by default. See
18146 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18148 2011-05-20 Kenichi Handa <handa@m17n.org>
18150 * composite.c (find_automatic_composition): Fix previous change.
18152 2011-05-20 Glenn Morris <rgm@gnu.org>
18154 * lisp.mk: New file, split from Makefile.in.
18155 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18156 (shortlisp): Remove.
18157 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18159 2011-05-19 Glenn Morris <rgm@gnu.org>
18161 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18162 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18163 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18164 (lisp): Set the order to that of loadup.el.
18165 (shortlisp): Make it a copy of $lisp.
18166 (SOME_MACHINE_LISP): Remove.
18167 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18168 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18170 2011-05-18 Kenichi Handa <handa@m17n.org>
18172 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18173 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18174 (find_automatic_composition): Mostly rewrite for efficiency.
18176 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18178 * makefile.w32-in: Update dependencies.
18180 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18182 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18183 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18185 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18187 Fix some integer overflow issues, such as string length overflow.
18189 * insdel.c (count_size_as_multibyte): Check for string overflow.
18191 * character.c (lisp_string_width): Check for string overflow.
18192 Use EMACS_INT, not int, for string indexes and lengths; in
18193 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18194 the resulting string length overflows an EMACS_INT; instead,
18195 report a string overflow if no precision given. When checking for
18196 precision exhaustion, use a check that cannot possibly have
18197 integer overflow. (Bug#8675)
18198 * character.h (lisp_string_width): Adjust to new signature.
18200 * alloc.c (string_overflow): New function.
18201 (Fmake_string): Use it. This doesn't change behavior, but saves
18202 a few bytes and will simplify future changes.
18203 * character.c (string_escape_byte8): Likewise.
18204 * lisp.h (string_overflow): New decl.
18206 Fixups, following up to the user-interface timestamp change.
18207 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18208 for UI timestamps, instead of unsigned long.
18209 * msdos.c (mouse_get_pos): Likewise.
18210 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18211 * w32gui.h (Time): Define by including "systime.h" rather than by
18212 declaring it ourselves. (Bug#8664)
18214 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18215 * image.c (clear_image_cache): Likewise.
18217 * term.c (term_mouse_position): Don't assume time_t wraparound.
18219 Be more systematic about user-interface timestamps.
18220 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18221 and sometimes 'EMACS_UINT', to represent these timestamps.
18222 This change causes it to use 'Time' uniformly, as that's what X uses.
18223 This makes the code easier to follow, and makes it easier to catch
18224 integer overflow bugs such as Bug#8664.
18225 * frame.c (Fmouse_position, Fmouse_pixel_position):
18226 Use Time, not unsigned long, for user-interface timestamps.
18227 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18228 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18229 * keyboard.h (last_event_timestamp): Likewise.
18230 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18231 * menu.h (xmenu_show): Likewise.
18232 * term.c (term_mouse_position): Likewise.
18233 * termhooks.h (struct input_event.timestamp): Likewise.
18234 (struct terminal.mouse_position_hook): Likewise.
18235 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18236 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18237 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18238 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18239 what it was before.
18240 * menu.h, termhooks.h: Include "systime.h", for Time.
18242 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18243 Don't assume that the difference between two unsigned long values
18244 can fit into an integer. At this point, we know button_down_time
18245 <= event->timestamp, so the difference must be nonnegative, so
18246 there's no need to cast the result if double-click-time is
18247 nonnegative, as it should be; check that it's nonnegative, just in
18248 case. This bug is triggered when events are more than 2**31 ms
18249 apart (about 25 days). (Bug#8664)
18251 * xselect.c (last_event_timestamp): Remove duplicate decl.
18252 (x_own_selection): Remove needless cast to unsigned long.
18254 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18255 that always fit in int. Use a sentinel instead of a counter, to
18256 avoid a temp and to allay GCC's concerns about possible int overflow.
18257 * frame.h (struct frame): Use int for menu_bar_items_used
18258 instead of EMACS_INT, since it always fits in int.
18260 * menu.c (grow_menu_items): Check for int overflow.
18262 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18264 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18265 Before, the code was not consistent. These values cannot exceed
18266 2**31 - 1 so there's no need to make them unsigned.
18267 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18268 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18269 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18271 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18273 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18274 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18275 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18276 presumably because the widths might not match.
18278 * window.c (size_window): Avoid needless test at loop start.
18280 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18282 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18284 2011-05-12 Drew Adams <drew.adams@oracle.com>
18286 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18288 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18290 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18291 `width' to `bar_area_x' and `bar_area_width', respectively.
18292 (x_scroll_run): Take account of fringe background extension.
18294 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18295 Rename local vars `left' and `width' to `bar_area_x' and
18296 `bar_area_width', respectively.
18297 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18298 background extension.
18300 2011-05-10 Jim Meyering <meyering@redhat.com>
18302 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18304 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18306 * image.c (Finit_image_library): Return t for built-in image types,
18307 like pbm and xbm. (Bug#8640)
18309 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18311 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18313 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18315 * w32console.c (Fset_screen_color): Doc fix.
18316 (Fget_screen_color): New function.
18317 (syms_of_ntterm): Defsubr it.
18319 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18320 unlink the temporary file if Fcall_process didn't create it in the
18322 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18323 child process will be redirected to a file specified with `:file'.
18324 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18325 cue to call_process_cleanup not to close that handle.
18327 2011-05-07 Ben Key <bkey76@gmail.com>
18329 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18330 one of two shell specific rules, either bootstrap-temacs-CMD or
18331 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18332 to the previous implementation of the bootstrap-temacs rule.
18333 The bootstrap-temacs-CMD rule is similar to the previous
18334 implementation of the bootstrap-temacs rule except that it
18335 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18338 These changes, along with some changes to nt/configure.bat,
18339 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18340 earlier fix to add support for --cflags and --ldflags options
18341 that include quotes so that it works whether make uses cmd or
18344 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18346 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18347 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18349 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18350 a string. Handle both cases.
18351 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18352 (Fdbus_register_method): Use Qinvalid_function.
18354 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18356 * makefile.w32-in: Update dependencies.
18357 (LISP_H): Add inttypes.h and stdin.h.
18358 (PROCESS_H): Add unistd.h.
18360 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18362 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18363 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18365 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18367 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18369 * term.c (vfatal): Remove stray call to va_end.
18370 It's not needed and the C Standard doesn't allow it here anyway.
18372 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18373 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18375 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18378 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18380 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18382 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18384 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18386 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18388 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18389 * charset.c (Fdefine_charset_internal): Don't initialize
18390 charset.code_space[15]. The value was garbage, on hosts with
18391 32-bit int (Bug#8600).
18393 * lread.c (read_integer): Be more consistent with string-to-number.
18394 Use string_to_number to do the actual conversion; this avoids
18395 rounding errors and fixes some other screwups. Without this fix,
18396 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18397 (digit_to_number): Move earlier, for benefit of read_integer.
18398 Return -1 if the digit is out of range for the base, -2 if it is
18399 not a digit in any supported base. (Bug#8602)
18401 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18403 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18404 to match comment at start of function. This also removes a
18405 GCC warning about overflow in a 32+64-bit port.
18407 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18409 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18410 Reported by Stefan Monnier in
18411 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18412 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18413 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18415 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18416 (EMACS_UINTPTR): Likewise, with uintptr_t.
18418 * lisp.h: Prefer 64-bit EMACS_INT if available.
18419 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18420 on 32-bit hosts that have 64-bit int, so that they can access
18422 However, temporarily disable this change unless the temporary
18423 symbol WIDE_EMACS_INT is defined.
18425 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18427 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18428 This removes an assumption that EMACS_INT and long are the same
18429 width as pointers. The assumption is true for Emacs porting targets
18430 now, but we want to make other targets possible.
18431 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18432 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18433 In the rest of the code, change types of integers that hold casted
18434 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18435 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18436 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18437 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18438 No need to cast type when ORing.
18439 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18440 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18441 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18442 assume EMACS_INT is the same width as char *.
18443 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18444 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18445 Remove no-longer-needed casts.
18446 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18447 (xg_tool_bar_help_callback, xg_make_tool_item):
18448 Use EMACS_INTPTR to hold an integer
18449 that will be cast to void *; this can avoid a GCC warning
18450 if EMACS_INT is not the same width as void *.
18451 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18452 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18453 (current_message_1, set_message_1):
18454 Use a local to convert to proper width without a cast.
18455 * xmenu.c (dialog_selection_callback): Likewise.
18457 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18458 Also, don't assume VALBITS / RAND_BITS is less than 5,
18459 and don't rely on undefined behavior when shifting a 1 left into
18461 * lisp.h (get_random): Change signature to match.
18463 * lread.c (hash_string): Use size_t, not int, for hash computation.
18464 Normally we prefer signed values; but hashing is special, because
18465 it's better to use unsigned division on hash table sizes so that
18466 the remainder is nonnegative. Also, size_t is the natural width
18467 for hashing into memory. The previous code used 'int', which doesn't
18468 retain enough info to hash well into very large tables.
18469 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18471 * dbusbind.c: Don't possibly lose pointer info when converting.
18472 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18473 Use XPNTR rather than XHASH, so that the high-order bits of
18474 the pointer aren't lost when converting through void *.
18476 * eval.c (Fautoload): Don't double-shift a pointer.
18478 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18480 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18482 * gnutls.c (DEF_GNUTLS_FN):
18483 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18485 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18487 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18490 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18492 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18493 New version that can reserve upto 2GB of heap space.
18495 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18497 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18499 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18501 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18502 `gnutls_certificate_set_x509_key_file'.
18504 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18506 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18507 Update dependencies.
18509 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18511 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18512 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18513 Remove unused parameter `fildes'.
18514 * process.c (read_process_output, send_process): Don't pass it.
18516 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18518 Fix previous change: the library cache is defined in w32.c.
18519 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18520 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18522 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18524 Implement dynamic loading of GnuTLS on Windows.
18526 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18527 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18528 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18531 * gnutls.c (Qgnutls_dll): Define.
18532 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18533 (gnutls_*): Declare function pointers.
18534 (init_gnutls_functions): New function to initialize function pointers.
18535 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)

18537 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18538 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18539 (emacs_gnutls_write, emacs_gnutls_read)
18540 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18541 (Fgnutls_available_p): New function.
18542 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18543 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18544 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18546 * image.c: Include w32.h.
18547 (Vimage_type_cache): Delete.
18548 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18549 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18550 (w32_delayed_load): Move to w32.c.
18552 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18554 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18555 (w32_delayed_load): Move from image.c. When loading a library, record
18556 its filename in the :loaded-from property of the library id.
18557 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18558 Initialize and staticpro them.
18559 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18561 * process.c: Include lisp.h before w32.h, not after.
18562 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18563 instead of gnutls_record_check_pending.
18565 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18567 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18569 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18570 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18573 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18575 * xterm.c (x_set_frame_alpha): Do not set property on anything
18576 else than FRAME_X_OUTER_WINDOW (Bug#8608).

18594 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18596 * callproc.c: Indentation fixup.
18598 * sysdep.c (wait_for_termination_1): Make static.
18599 (wait_for_termination, interruptible_wait_for_termination):
18600 Move after wait_for_termination_1.
18602 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18604 * sysdep.c (interruptible_wait_for_termination): New function
18605 which is like wait_for_termination, but allows keyboard
18608 * callproc.c (Fcall_process): Add (:file "file") as an option for
18610 (Fcall_process_region): Ditto.
18612 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18614 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18615 rather than `XVECTOR (FOO)->size'.
18617 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18618 inttypes.h, as a gnulib replacement is used if it not available in
18621 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18623 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18624 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18625 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18627 * coding.c (coding_alloc_by_realloc): Error out if destination
18628 will grow beyond MOST_POSITIVE_FIXNUM.
18629 (decode_coding_emacs_mule): Abort if there isn't enough place in

18642 * window.c (window_scroll_line_based): Use a marker instead of
18643 simple variables to record original value of point. (Bug#7952)
18645 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18646 produced by %s or %c overflows available buffer space. (Bug#8545)
18648 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18650 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18651 (SIZE_MAX): Move defn after all includes, as they might #define it.
18653 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18655 * w32.c (init_environment): Warn about defaulting HOME to C:\.

18675 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18677 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18679 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18681 * makefile.w32-in: Update dependencies.
18683 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18685 Improve `doprnt' and its usage. (Bug#8545)
18686 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18687 `format_end'. Remove support for %l as a conversion specifier.
18688 Don't use xrealloc. Improve diagnostics when the %l size modifier
18689 is used. Update the commentary.
18691 * eval.c (verror): Simplify calculation of size_t.
18693 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18696 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18698 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18701 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18703 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18704 This makes this file independent of the recent pseudovector change.
18706 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18708 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18710 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18711 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18712 Remove unused local.
18713 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18715 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18716 GCC 4.6.0 optimizes based on type-based alias analysis.
18717 For example, if b is of type struct buffer * and v of type struct
18718 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18719 != &v->size, and therefore "v->size = 1; b->size = 2; return
18720 v->size;" must therefore return 1. This assumption is incorrect
18721 for Emacs, since it type-puns struct Lisp_Vector * with many other
18722 types. To fix this problem, this patch adds a new type struct
18723 vectorlike_header that documents the constraints on layout of vectors
18724 and pseudovectors, and helps optimizing compilers not get fooled
18725 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18726 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18727 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18729 (XSETPVECTYPE): Rewrite in terms of new macro.
18730 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18731 This is a bit clearer, and further avoids the possibility of
18732 undesirable aliasing.
18733 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18734 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18735 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18736 since Lisp_Subr is a special case (no "next" field).
18737 (ASIZE): Now uses header.size rather than size.
18738 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18739 to avoid the hassle of writing XVECTOR (foo)->header.size.
18740 (struct vectorlike_header): New type.
18741 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18742 object, to help avoid aliasing.
18743 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18744 (SUBRP): Likewise, since Lisp_Subr is a special case.
18745 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18746 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18747 (struct Lisp_Hash_Table): Combine first two members into a single
18748 struct vectorlike_header member. All uses of "size" and "next" members
18749 changed to be "header.size" and "header.next".
18750 * buffer.h (struct buffer): Likewise.
18751 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18752 * frame.h (struct frame): Likewise.
18753 * process.h (struct Lisp_Process): Likewise.
18754 * termhooks.h (struct terminal): Likewise.
18755 * window.c (struct save_window_data, struct saved_window): Likewise.
18756 * window.h (struct window): Likewise.
18757 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18758 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18759 * buffer.c (init_buffer_once): Likewise.
18760 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18762 * process.c (Fformat_network_address): Use local var for size,
18765 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18767 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18768 * data.c (atof): Remove decl; no longer used or needed.
18769 (digit_to_number): Move to lread.c.
18770 (Fstring_to_number): Use new string_to_number function, to be
18771 consistent with how the Lisp reader treats infinities and NaNs.
18772 Do not assume that floating-point numbers represent EMACS_INT
18773 without losing information; this is not true on most 64-bit hosts.
18774 Avoid double-rounding errors, by insisting on integers when
18775 parsing non-base-10 numbers, as the documentation specifies.
18776 * lisp.h (string_to_number): New decl, replacing ...
18777 (isfloat_string): Remove.
18778 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18779 (read1): Do not accept +. and -. as integers; this
18780 appears to have been a coding error. Similarly, do not accept
18781 strings like +-1e0 as floating point numbers. Do not report
18782 overflow for integer overflows unless the base is not 10 which
18783 means we have no simple and reliable way to continue.
18784 Break out the floating-point parsing into a new
18785 function string_to_number, so that Fstring_to_number parses
18786 floating point numbers consistently with the Lisp reader.
18787 (digit_to_number): Move here from data.c. Make it static inline.
18788 (E_CHAR, EXP_INT): Remove, replacing with ...
18789 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18790 (string_to_number): New function, replacing isfloat_string.
18791 This function checks for valid syntax and produces the resulting
18792 Lisp float number too. Rework it so that string-to-number
18793 no longer mishandles examples like "1.0e+". Use strtoumax,
18794 so that overflow for non-base-10 numbers is reported only when
18795 there's no portable and simple way to convert to floating point.
18797 * textprop.c (set_text_properties_1): Rewrite for clarity,
18798 and to avoid GCC warning about integer overflow.
18800 * intervals.h (struct interval): Use EMACS_INT for members
18801 where EMACS_UINT might cause problems. See
18802 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18803 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18804 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18806 (offset_intervals): Tell GCC not to worry about length overflow
18807 when negating a negative length.
18809 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18810 (overrun_check_free): Likewise.
18812 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18813 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18816 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18817 (gnutls_make_error): Rename local to avoid shadowing.
18818 (gnutls_emacs_global_deinit): ifdef out; not used.
18819 (Fgnutls_boot): Use const for pointer to readonly storage.
18820 Comment out unused local. Fix pointer signedness problems.
18822 * lread.c (openp): Don't stuff size_t into an 'int'.
18823 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18824 about possible signed overflow.
18826 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18827 (GDK_KEY_g): Don't define if already defined.
18828 (xg_prepare_tooltip): Avoid pointer signedness problem.
18829 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18831 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18832 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18834 * xfns.c (Fx_window_property): Simplify a bit,
18835 to make a bit faster and to avoid GCC 4.6.0 warning.
18836 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18838 * fns.c (internal_equal): Don't assume size_t fits in int.
18840 * alloc.c (compact_small_strings): Tighten assertion a little.
18842 Replace pEd with more-general pI, and fix some printf arg casts.
18843 * lisp.h (pI): New macro, generalizing old pEd macro to other
18844 conversion specifiers. For example, use "...%"pI"d..." rather
18845 than "...%"pEd"...".
18846 (pEd): Remove. All uses replaced with similar uses of pI.
18847 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18848 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18849 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18850 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18851 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18852 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18853 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18855 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18856 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18857 * print.c (safe_debug_print, print_object): Likewise.
18858 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18860 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18861 avoiding the 0 flag, which is not portable.
18862 * process.c (Fmake_network_process): Use pI to avoid cast.
18863 * region-cache.c (pp_cache): Likewise.
18864 * xdisp.c (decode_mode_spec): Likewise.
18865 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18866 behavior on 64-bit hosts with printf arg.
18867 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18868 (x_stop_queuing_selection_requests): Likewise.
18869 (x_get_window_property): Don't truncate byte count to an 'int'
18872 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18873 here, since it parses constructs like leading '-' and spaces,
18874 which are not wanted; and it overflows with large numbers.
18875 Instead, simply match F[0-9]+, which is what is wanted anyway.
18877 * alloc.c: Remove unportable assumptions about struct layout.
18878 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18879 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18880 (allocate_vectorlike, make_pure_vector): Use the new macros,
18881 plus offsetof, to remove unportable assumptions about struct layout.
18882 These assumptions hold on all porting targets that I know of, but
18883 they are not guaranteed, they're easy to remove, and removing them
18884 makes further changes easier.
18886 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18887 This doesn't fix a bug but makes the code clearer.
18888 (string_overrun_cookie): Now const. Use initializers that
18889 don't formally overflow signed char, to avoid warnings.
18890 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18891 can cause Emacs to crash when string overrun checking is enabled.
18892 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18893 multiple of sizeof (EMACS_INT); it need not be, if
18894 alignof(EMACS_INT) < sizeof (EMACS_INT).
18895 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18897 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
18899 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
18901 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
18903 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
18904 supposed to be handshaking. (Bug#8556)
18905 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18907 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
18909 * lisp.h (Qdebug): List symbol.
18910 * eval.c (Qdebug): Restore global linkage.

18912 (handle_user_signal): Break into debugger when debug-on-event
18913 matches the current signal symbol.
18915 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18917 * alloc.c (check_sblock, check_string_bytes)
18918 (check_string_free_list): Convert to standard C.
18920 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18922 * w32.c (emacs_gnutls_push): Fix typo.
18924 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18926 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18927 "cast to pointer from integer of different size".
18929 Improve doprnt and its use in verror. (Bug#8545)
18930 * doprnt.c (doprnt): Document the set of format control sequences
18931 supported by the function. Use SAFE_ALLOCA instead of always
18934 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18935 is one byte too soon. Don't use xrealloc; instead xfree and
18938 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18940 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18943 * gnutls.c: Renamed global_initialized to
18944 gnutls_global_initialized. Added internals for the
18945 :verify-hostname-error, :verify-error, and :verify-flags
18946 parameters of `gnutls-boot' and documented those parameters in the
18947 docstring. Start callback support.
18948 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18949 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18950 on error. Return error code.
18951 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18952 (emacs_gnutls_read): Likewise.
18953 (Fgnutls_boot): Return handshake error code.
18954 (emacs_gnutls_handle_error): New function.
18955 (wsaerror_to_errno): Likewise.

19010 changes in globals.h immediately force recompilation.
19011 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19012 $(CURDIR)/s/ms-w32.h.

19017 <char-direction-table>: Deleted.
19019 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19021 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19022 * doprnt.c: Include limits.h.
19023 (SIZE_MAX): New macro.
19024 (doprnt): Return a size_t value. 2nd arg is now size_t.
19025 Many local variables are now size_t instead of int or unsigned.
19026 Improve overflow protection. Support `l' modifier for integer
19027 conversions. Support %l conversion. Don't assume an EMACS_INT
19028 argument for integer conversions and for %c.
19030 * lisp.h (doprnt): Restore prototype.
19032 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19033 $(SRC)/character.h.
19035 * Makefile.in (base_obj): Add back doprnt.o.
19037 * deps.mk (doprnt.o): Add back prerequisites.
19038 (callint.o): Depend on character.h.
19040 * eval.c (internal_lisp_condition_case): Include the handler
19041 representation in the error message.
19042 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19043 when breaking from the loop.
19045 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19047 * callint.c (Fcall_interactively): When displaying error message
19048 about invalid control letter, pass the character's codepoint, not
19049 a pointer to its multibyte form. Improve display of the character
19050 in octal and display also its hex code.
19052 * character.c (char_string): Use %x to display the (unsigned)
19053 codepoint of an invalid character, to avoid displaying a bogus
19056 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19057 `error', not SYMBOL_NAME itself.
19059 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19060 character arguments to `error'.
19062 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19063 to `error' in error message about FINAL_CHAR argument. Make sure
19064 FINAL_CHAR is a character, and use %c when it is passed as
19065 argument to `error'.

19129 Define only if needed.
19131 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
19132 by pacifying GCC about it. Maybe it's time to retire it?

19608 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
19609 * lisp.h: Remove these decls.
19611 * buffer.c (buffer_count): Remove unused var.
19613 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
19614 so that it's not optimized away.
19615 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
19616 * dispextern.h (bidi_dump_cached_states): Remove, since it's
19617 exported only to the debugger.
19619 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
19620 * atimer.h (run_all_atimers): Remove; not exported.
19622 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19623 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19624 was inaccessible from Lisp.
19625 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19626 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19628 alloc.c: Import and export fewer symbols, and remove unused items.
19629 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19631 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19632 it's not optimized away by whole-program optimization.
19633 (message_enable_multibyte, free_misc): Remove.
19634 (catchlist, handlerlist, mark_backtrace):
19635 Declare only if BYTE_MARK_STACK.
19636 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
19637 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
19638 (message_enable_multibyte): Remove decl.
19639 (free_misc, interval_free_list, float_block, float_block_index):

19644 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
19645 (mark_backtrace): Define only if BYTE_MARK_STACK.
19646 * xdisp.c (message_enable_multibyte): Now static.
19648 Declare Lisp_Object Q* variables to be 'static' if not exported.
19649 This makes it easier for human readers (and static analyzers)
19650 to see whether these variables are used from other modules.
19651 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
19652 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
19653 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

19657 * xmenu.c, xselect.c:
19658 Declare Q* vars static if they are not used in other modules.

19660 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
19661 Remove decls of unexported vars.
19662 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19664 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19666 Make Emacs functions such as Fatom 'static' by default.
19667 This makes it easier for human readers (and static analyzers)
19668 to see whether these functions can be called from other modules.
19669 DEFUN now defines a static function. To make the function external
19670 so that it can be used in other C modules, use the new macro DEFUE.
19671 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19672 (Finit_image_library):
19673 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
19674 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19675 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19676 Remove decls, since these functions are now static.
19677 (Funintern, Fget_internal_run_time): New decls, since these functions
19678 were already external.
19680 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19681 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

19687 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19688 Mark functions with DEFUE instead of DEFUN,
19689 if they are used in other modules.
19690 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19691 decls for now-static functions.
19692 * buffer.h (Fdelete_overlay): Remove decl.
19693 * callproc.c (Fgetenv_internal): Mark as internal.

19702 * image.c (Finit_image_library): New forward static decl.
19703 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

19728 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19730 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19731 when at ZV. (Bug#8487)
19733 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19735 * charset.c (Fclear_charset_maps): Use xfree instead of free.

19738 * sound.c (sound_cleanup, alsa_close): Likewise.
19739 * termcap.c (tgetent): Likewise.
19740 * xfns.c (x_default_font_parameter): Likewise.
19741 * xsettings.c (read_and_apply_settings): Likewise.
19743 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19744 (overrun_check_free): Protoize.
19746 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19748 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19749 since callers should never pass a negative size.
19750 Change the signature to match that of plain 'read' and 'write'; see
19751 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19752 * lisp.h: Update prototypes of emacs_write and emacs_read.
19754 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19756 * xdisp.c (redisplay_window): Don't try to determine the character
19757 position of the scroll margin if the window start point w->startp
19758 is outside the buffer's accessible region. (Bug#8468)
19760 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19762 Fix write-region and its subroutines for buffers > 2GB.
19763 * fileio.c (a_write, e_write): Modify declaration of arguments and
19764 local variables to support buffers larger than 2GB.
19765 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19767 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19768 argument, local variables, and return value.
19770 * lisp.h: Update prototypes of emacs_write and emacs_read.
19772 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19774 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19776 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19778 Fix more problems found by GCC 4.6.0's static checks.
19780 * xdisp.c (vmessage): Use a better test for character truncation.
19782 * charset.c (load_charset_map): <, not <=, for optimization,
19783 and to avoid potential problems with integer overflow.
19784 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19785 * casetab.c (set_identity, shuffle): Likewise.
19786 * editfns.c (Fformat): Likewise.
19787 * syntax.c (skip_chars): Likewise.
19789 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19790 This also lets GCC 4.6.0 generate slightly better loop code.
19792 * callint.c (Fcall_interactively): <, not <=, for optimization.
19793 (Fcall_interactively): Count the number of arguments produced,
19794 not the number of arguments given. This is simpler and lets GCC
19795 4.6.0 generate slightly better code.
19797 * ftfont.c: Distingish more carefully between FcChar8 and char.
19798 The previous code passed unsigned char * to a functions like
19799 strlen and xstrcasecmp that expect char *, which does not
19800 conform to the C standard.
19801 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19802 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19803 char * when the C standard requires it.
19805 * keyboard.c (read_char): Remove unused var.
19807 * eval.c: Port to Windows vsnprintf (Bug#8435).
19808 Include <limits.h>.
19809 (SIZE_MAX): Define if the headers do not.
19810 (verror): Do not give up if vsnprintf returns a negative count.
19811 Instead, grow the buffer. This ports to Windows vsnprintf, which
19812 does not conform to C99. Problem reported by Eli Zaretskii.
19813 Also, simplify the allocation scheme, by avoiding the need for
19814 calling realloc, and removing the ALLOCATED variable.
19816 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19818 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19819 But keep the doprint source code for now, as we might revamp it
19820 and use it again (Bug#8435).
19821 * lisp.h (doprnt): Remove.
19822 * Makefile.in (base_obj): Remove doprnt.o.
19823 * deps.mk (doprnt.o): Remove.
19825 error: Print 32- and 64-bit integers portably (Bug#8435).
19826 Without this change, on typical 64-bit hosts error ("...%d...", N)
19827 was used to print both 32- and 64-bit integers N, which relied on
19828 undefined behavior.
19829 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19830 * lisp.h (error, verror): Mark as printf-like functions.
19831 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19832 Report overflow in size calculations when allocating printf buffer.
19833 Do not truncate output string at its first null byte.
19834 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19835 Truncate the output at a character boundary, since vsnprintf does not
19837 * charset.c (check_iso_charset_parameter): Convert internal
19838 character to string before calling 'error', since %c now has the
19840 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19841 overflow when computing char to be passed to 'error'. Do not
19842 pass Lisp_Object to 'error'; pass the integer instead.
19843 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19844 formatted with plain %d.
19846 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19848 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19850 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19852 * xterm.c (x_catch_errors): Remove duplicate declaration.
19854 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19856 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19858 2011-04-10 Jim Meyering <meyering@redhat.com>
19860 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19861 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19862 return ssize_t not "int", and use size_t as the buffer length.
19863 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19864 * gnutls.h: Update declarations.
19865 * process.c (read_process_output): Use ssize_t, to match.
19866 (send_process): Likewise.
19868 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19870 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19872 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19874 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19875 Use unsigned char, to match FcChar8 type definition.
19877 * xterm.c (handle_one_xevent):
19878 * xmenu.c (create_and_show_popup_menu):
19879 * xselect.c (x_decline_selection_request)
19880 (x_reply_selection_request): Avoid type-punned deref of X events.
19882 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19884 Fix some uses of `int' instead of EMACS_INT.
19885 * search.c (string_match_1, fast_string_match)
19886 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19887 (scan_buffer, find_next_newline_no_quit)
19888 (find_before_next_newline, search_command, Freplace_match)
19889 (Fmatch_data): Make some `int' variables be EMACS_INT.
19891 * xdisp.c (display_count_lines): 3rd argument and return value now
19892 EMACS_INT. All callers changed.
19893 (pint2hrstr): Last argument is now EMACS_INT.
19895 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19896 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19897 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

19907 (encode_designation_at_bol, encode_coding_iso_2022)
19908 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19909 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19911 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19912 (encode_invocation_designation): Last argument P_NCHARS is now
19914 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19915 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19917 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19920 * ccl.c (Fccl_execute_on_string): Declare some variables
19923 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19925 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19927 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19929 * process.c (Fformat_network_address): Doc fix.
19931 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19933 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19935 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19937 * keyboard.c (read_char): Call Lisp function help-form-show,
19938 instead of using internal_with_output_to_temp_buffer.
19939 (Qhelp_form_show): New var.
19940 (syms_of_keyboard): Use DEFSYM macro.
19942 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19946 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19948 * process.c (Flist_processes): Remove to Lisp.
19949 (list_processes_1): Delete.
19951 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19953 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19955 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19957 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19959 Fix more problems found by GCC 4.6.0's static checks.
19961 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19963 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19965 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19967 * xdisp.c (vmessage): Mark as a printf-like function.
19969 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19971 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19973 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19974 printf-like functions.
19975 (tiff_load): Add casts to remove these marks before passing them
19976 to system-supplied API.
19978 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19980 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19981 This avoids several warnings with gcc -Wstrict-overflow.
19982 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19983 directly, rather than having caller test rule sign. This avoids
19984 some unnecessary tests.
19985 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19986 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19987 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19989 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19990 (xfont_open): Avoid unnecessary tests.
19992 * composite.c (composition_gstring_put_cache): Use unsigned integer.

20001 by using the new macro.
20003 * textprop.c (set_text_properties_1): Change while to do-while,
20004 since the condition is always true at first.
20006 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20007 (interval_deletion_adjustment): Return unsigned value.
20010 * process.c (list_processes_1, create_pty, read_process_output):

20026 * print.c (print_error_message): Avoid int overflow.
20028 * font.c (font_list_entities): Redo for clarity,

20044 (wordify): Omit three unnecessary tests.
20046 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

20051 * dired.c (file_name_completion): Remove var that is set but not used.
20053 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20055 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20056 (Finsert_file_contents): Remove unnecessary code checking fd.
20058 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20059 Check for integer overflow on size calculations.
20061 * buffer.c (Fprevious_overlay_change): Remove var that is set
20064 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20065 Remove vars that are set but not used.
20066 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20067 (timer_check_2): Mark vars as initialized.
20069 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20071 * image.c (lookup_image): Remove var that is set but not used.
20072 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20074 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20075 that are set but not used.
20077 * xfns.c (make_invisible_cursor): Don't return garbage
20078 if XCreateBitmapFromData fails (Bug#8410).
20080 * xselect.c (x_get_local_selection, x_handle_property_notify):
20081 Remove vars that are set but not used.
20083 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20084 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20086 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20087 Remove var that is set but not used.
20088 (scroll_bar_windows_size): Now size_t, not int.
20089 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20090 Check for overflow.
20092 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20093 (map_tty_color) [!defined MSDOS]: Likewise.
20095 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20097 * coding.c: Remove vars that are set but not used.
20098 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20099 All callers changed.
20100 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20101 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20102 (decode_coding_charset): Remove vars that are set but not used.
20104 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20105 that is set but not used.
20107 * print.c (print_object): Remove var that is set but not used.
20109 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20110 The gnulib version avoids calling malloc in the usual case,
20111 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20112 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20113 * filelock.c (current_lock_owner): Likewise.
20114 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20115 * sysdep.c: Include allocator.h, careadlinkat.h.
20116 (emacs_no_realloc_allocator): New static constant.
20117 (emacs_readlink): New function.
20118 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20119 ../lib/careadlinkat.h.
20121 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20123 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20124 first non-nil return value).

20138 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20139 and thereabouts. All callers changed.
20140 (get_per_char_metric): Remove parameter `f', unused since
20141 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20143 2011-04-02 Jim Meyering <meyering@redhat.com>
20145 do not dereference NULL upon failed strdup
20146 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20147 (ns_get_family): Likewise.
20149 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20151 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20153 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20155 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20158 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20160 Add lexical binding.
20162 * window.c (Ftemp_output_buffer_show): New fun.
20163 (Fsave_window_excursion):
20164 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20166 * lread.c (lisp_file_lexically_bound_p): New function.
20167 (Fload): Bind Qlexical_binding.
20168 (readevalloop): Remove `evalfun' arg.
20169 Bind Qinternal_interpreter_environment.
20170 (Feval_buffer): Bind Qlexical_binding.
20171 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20173 (syms_of_lread): Declare `lexical-binding'.
20175 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20177 * keyboard.c (eval_dyn): New fun.
20178 (menu_item_eval_property): Use it.
20180 * image.c (parse_image_spec): Use Ffunctionp.
20182 * fns.c (concat, mapcar1): Accept byte-code-functions.
20184 * eval.c (Fsetq): Handle lexical vars.
20185 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20186 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20187 (FletX, Flet): Obey lexical binding.
20188 (Fcommandp): Handle closures.
20189 (Feval): New `lexical' arg.
20190 (eval_sub): New function extracted from Feval. Use it almost
20191 everywhere where Feval was used. Look up vars in lexical env.
20193 (Ffunctionp): Move from subr.el.
20194 (Ffuncall): Handle closures.
20195 (apply_lambda): Remove `eval_flags'.
20196 (funcall_lambda): Handle closures and new byte-code-functions.
20197 (Fspecial_variable_p): New function.
20198 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20199 but without exporting it to Lisp.
20201 * doc.c (Fdocumentation, store_function_docstring):
20202 * data.c (Finteractive_form): Handle closures.
20204 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20207 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20209 (exec_byte_code): New function extracted from Fbyte_code to handle new
20210 calling convention for byte-code-functions. Add new byte-codes.
20212 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20214 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20216 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20218 * xdisp.c (redisplay_internal): Fix prototype.
20220 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20222 * xdisp.c (SCROLL_LIMIT): New macro.
20223 (try_scrolling): Use it when setting scroll_limit.
20224 Limit scrolling to 100 screen lines.
20225 (redisplay_window): Even when falling back on "recentering",
20226 position point in the window according to scroll-conservatively,
20227 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20229 (try_scrolling): When point is above the window, allow searching
20230 as far as scroll_max, or one screenful, to compute vertical
20231 distance from PT to the scroll margin position. This prevents
20232 try_scrolling from unnecessarily failing when
20233 scroll-conservatively is set to a value slightly larger than the
20234 window height. Clean up the case of PT below the margin at bottom
20235 of window: scroll_max can no longer be INT_MAX. When aggressive
20236 scrolling is in use, don't let point enter the opposite scroll
20237 margin as result of the scroll.
20238 (syms_of_xdisp) <scroll-conservatively>: Document the
20239 threshold of 100 lines for never-recentering scrolling.
20241 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20243 * dispextern.h (move_it_by_lines):
20244 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

20246 (message_log_check_duplicate): Remove parameters `prev_bol' and
20247 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20248 (redisplay_internal): Remove parameter `preserve_echo_area',
20249 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20251 * indent.c (Fvertical_motion):
20252 * window.c (window_scroll_pixel_based, Frecenter):
20253 Don't pass `need_y_p' to `move_it_by_lines'.
20255 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20257 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20258 steal a few bits to be more compact.
20259 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20260 Remove unneeded casts.
20262 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20264 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20266 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20267 binding" message (bug#7967).
20269 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20271 Fix more problems found by GCC 4.6.0's static checks.
20273 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20274 Remove unused local var.
20276 * editfns.c (Fmessage_box): Remove unused local var.
20278 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20279 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20280 Omit unused local vars.
20281 * window.c (shrink_windows): Omit unused local var.
20282 * menu.c (digest_single_submenu): Omit unused local var.
20283 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20284 Omit unused local var.
20286 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20287 Don't assume string length fits in int.
20288 (keyremap_step, read_key_sequence): Use size_t for sizes.
20289 (read_key_sequence): Don't check last_real_key_start redundantly.
20291 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20292 instead of alloca (Bug#8344).
20294 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20295 (Fbacktrace_frame): Don't assume nframes fits in int.
20297 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20299 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20302 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20304 * cm.c (calccost): Turn while-do into do-while, for clarity.
20306 * keyboard.c (syms_of_keyboard): Use the same style as later
20307 in this function when indexing through an array. This also
20308 works around GCC bug 48267.
20310 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20312 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20314 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20315 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20317 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20318 This avoids undefined behavior on integer overflow, and is a bit
20319 more convenient anyway since it is compared to a size_t variable.
20321 Variadic C functions now count arguments with size_t, not int.
20322 This avoids an unnecessary limitation on 64-bit machines, which
20323 caused (substring ...) to crash on large vectors (Bug#8344).

20333 * fns.c (concat): Likewise.
20334 * frame.c (x_set_frame_parameters): Likewise.
20335 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20336 0 if not found, not -1. All callers changed.
20338 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20339 (stack_copy_size): Now size_t, not int.
20340 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20342 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20344 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20345 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20346 All callers changed.

20361 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20362 don't set the hook to nil, but remove the offending function instead.
20363 (Qcommand_hook_internal): Remove, unused.
20364 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20365 Vcommand_hook_internal.
20367 * eval.c (enum run_hooks_condition): Remove.
20368 (funcall_nil, funcall_not): New functions.
20369 (run_hook_with_args): Call each function through a `funcall' argument.

20383 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20384 All callers changed.
20386 * w32.c (_wsa_errlist): Use braces for struct initializers.
20388 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

20535 * term.c (Fsuspend_tty, Fresume_tty):
20536 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20537 * window.c (temp_output_buffer_show):

20545 * buffer.c (Fkill_all_local_variables):
20546 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20548 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20549 unconditionally since it does the check itself.
20551 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20553 Fix more problems found by GCC 4.5.2's static checks.
20555 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20556 the first time through the loop, since we know p0 < p1 then.
20557 This also avoids a gcc -Wstrict-overflow warning.
20559 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20560 leading to a memory leak, possible in functions like
20561 load_charset_map_from_file that can allocate an unbounded number
20562 of objects (Bug#8318).
20564 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20565 that could (at least in theory) be that large.
20567 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20568 This is less likely to overflow, and avoids undefined behavior if
20569 overflow does occur. All callers changed. Use strtoul to scan
20570 for the unsigned long integer.
20571 (pint2hrstr): Simplify and tune code slightly.
20572 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20587 * process.c (Fmake_network_process): Use socklen_t, not int,
20588 where POSIX says socklen_t is required in portable programs.
20589 This fixes a porting bug on hosts like 64-bit HP-UX, where
20590 socklen_t is wider than int (Bug#8277).
20591 (Fmake_network_process, server_accept_connection):
20592 (wait_reading_process_output, read_process_output):
20595 * process.c: Rename or move locals to avoid shadowing.

20605 Make tparam.h and terminfo.c consistent.
20606 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20607 Include tparam.h instead, since it declares them.
20608 * cm.h (PC): Remove extern decl; tparam.h now does this.
20609 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20610 * terminfo.c: Include tparam.h, to check interfaces.
20611 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20612 (tparam): Adjust signature to match interface in tparam.h;
20613 this removes some undefined behavior. Check that outstring and len
20614 are zero, which they always are with Emacs.
20615 * tparam.h (PC, BC, UP): New extern decls.
20617 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20618 (xftfont_open): Rename locals to avoid shadowing.

20635 (find_automatic_composition, composition_adjust_point): Likewise.
20636 (composition_update_it): Mark var as initialized.
20637 (find_automatic_composition): Mark vars as initialized,
20638 with a FIXME (Bug#8290).

20642 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20643 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20644 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20645 to avoid shadowing.
20647 * textprop.c (property_change_between_p): Remove; unused.
20649 * intervals.c (interval_start_pos): Now static.
20651 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20657 Fix pointer signedness.
20658 (alsa_choose_format): Remove unused local var.
20659 (wav_play): Initialize a variable to 0, to prevent undefined
20660 behavior (Bug#8278).
20662 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20664 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20666 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20667 clobbering (Bug#8298).
20668 * sysdep.c (sys_subshell): Likewise.
20669 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20671 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20672 This should get cleaned up, so that child_setup has the
20673 same signature on all platforms.
20675 * callproc.c (call_process_cleanup): Now static.
20676 (relocate_fd): Rename locals to avoid shadowing.
20678 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20680 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20681 not to be necessary, and produces flickering.
20683 2011-03-20 Glenn Morris <rgm@gnu.org>
20685 * config.in: Remove file.
20687 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

20717 (sigchld_handler): Now static.
20719 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.

20732 Define only if needed.
20734 * unexelf.c (unexec): Name an expression,
20735 to avoid gcc -Wbad-function-cast warning.
20736 Use a different way to cause a compilation error if anyone uses
20737 n rather than nn, a way that does not involve shadowing.
20738 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20740 * deps.mk (unexalpha.o): Remove; unused.
20742 New file unexec.h, the (simple) interface for unexec (Bug#8267).

20837 (Fmemory_limit): Cast sbrk's returned value to char *.

20864 (WORDCHAR_P): Likewise. This one is never needed, but is used

20895 New macros, so that the caller can use some names other than
20896 gcpro1, gcpro2, etc.
20897 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20899 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20900 argument, for consistency with GCPRO2_VAR, etc: it is now the
20901 prefix of the variable, not the variable itself. All uses
20903 * dired.c (directory_files_internal, file_name_completion):
20904 Rename locals to avoid shadowing.
20906 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20907 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20908 dired.c's scmp function, had undefined behavior.
20909 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20910 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20911 * buffer.h: ... to here, because these macros use current_buffer,
20912 and the new implementation with inline functions needs to have
20913 current_buffer in scope now, rather than later when the macros
20915 (downcase, upcase1): New static inline functions.
20916 (DOWNCASE, UPCASE1): Reimplement using these functions.
20917 This avoids undefined behavior in expressions like
20918 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20919 from race conditions in accessing the global variables
20920 case_temp1 and case_temp2.

20948 so that gcc does not warn that these functions aren't declared.

20951 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20952 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.

20958 * buffer.c (fix_overlays_before): Mark locals as initialized.
20959 (fix_start_end_in_overlays): Likewise. This function should be
20960 simplified by using pointers-to-pointers, but that's a different

20964 (report_overlay_modification): Rename locals to avoid shadowing.

20969 to suppress a gcc -Wclobbered warning that does not seem to be right.
20970 (MAXPATHLEN): Define only if needed.

20973 * systty.h: ... to here, so that they can be checked.
20975 * fns.c (get_random, seed_random): Move extern decls from here ...
20976 * lisp.h: ... to here, so that they can be checked.
20978 * sysdep.c (reset_io): Now static.
20979 (wait_for_termination_signal): Remove; unused.
20981 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

20985 (DENSE_TABLE_SIZE): Remove; unused.
20986 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20987 (describe_map_tree):
20988 Rename locals to avoid shadowing.
20990 * keyboard.c: Declare functions static if they are not used elsewhere.

21331 (decode_coding_emacs_mule): Mark variables that gcc
21332 -Wuninitialized does not deduce are never used uninitialized.
21333 (detect_coding_iso_2022): Initialize a local variable that might
21334 be used uninitialized. Leave a FIXME because it's not clear that
21335 this initialization is needed. (Bug#8211)
21336 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
