3 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
4 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
5 digits for buffer positions, before misalignment starts. Display
6 "0" for integer "object" field.
7 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
8 Display the newline glyph more unambiguously.
10 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12 * nsterm.m (ns_draw_underwave):
13 * w32term.c (w32_draw_underwave):
14 * xterm.c (x_draw_underwave): Make underwave look more triangular
15 and also degrade gracefully for small fonts. (Bug#13000)
17 * nsterm.m (ns_draw_text_decoration):
18 * w32term.c (x_draw_glyph_string):
19 * xterm.c (x_draw_glyph_string): Don't use previous underline
20 thickness and position if previous underline type is underwave.

26 2013-01-02 Glenn Morris <rgm@gnu.org>
28 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
30 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
33 * dired.c (file_name_completion):

39 * minibuf.c (Ftry_completion):
40 * term.c (tty_ins_del_lines):
41 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
42 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
44 2012-12-31 Eli Zaretskii <eliz@gnu.org>
46 * w32.c (unsetenv): Set up the string passed to _putenv
48 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
49 for the bug this caused.
51 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
53 * coding.c (Qmac): Now static.
55 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
57 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
58 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
59 handlebox_widget. Set toolbar_in_hbox to false/true, set
60 toolbar_is_packed to true.
61 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
62 (update_frame_tool_bar): Check toolbar_is_packed for packing.
63 Show all on TOOLBAR_TOP_WIDGET.
64 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
65 by TOOLBAR_TOP_WIDGET.
66 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
67 Check toolbar_is_packed.
68 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
69 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
70 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
72 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
73 (xg_update_menubar): Update title only if
74 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
75 (xg_update_submenu): Skip tearoff only if
76 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
77 (xg_initialize): Initialize xg_detached_menus only if
78 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
80 * xterm.h (struct x_output): Surround handlebox_widget with
81 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
82 toolbar_in_hbox is bool.
84 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
86 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
87 (LIBS_GNUSTEP): Define.
88 (LIBES): Add $(LIBS_GNUSTEP).
89 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
91 2012-12-30 Eli Zaretskii <eliz@gnu.org>
93 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
94 continuation glyph on a TTY with an indication of an empty line.
97 2012-12-29 Eli Zaretskii <eliz@gnu.org>
99 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
100 file's SELinux context or ACLs successfully set, nil otherwise.
102 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
104 * w32proc.c (reader_thread): Avoid passing NULL handles to
105 SetEvent and WaitForSingleObject.
107 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
109 Port EXTERNALLY_VISIBLE to Clang 3.2.
110 * conf_post.h (__has_attribute): New macro.
111 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
113 2012-12-27 Glenn Morris <rgm@gnu.org>
115 * cygw32.c (Fcygwin_convert_file_name_to_windows)
116 (Fcygwin_convert_file_name_from_windows): Doc fixes.
118 2012-12-27 Eli Zaretskii <eliz@gnu.org>
120 * fileio.c (file_name_as_directory, directory_file_name): Accept
121 an additional argument MULTIBYTE to indicate whether the input C
122 came from a multibyte or a unibyte Lisp string; all callers
123 adjusted. Don't assume the input string is always multibyte.
125 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
126 don't ENCODE_FILE them, and return a unibyte string if the input
128 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
129 don't assume the input strings will always be multibyte. If the
130 input strings are multibyte, decode strings obtained from C
133 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
135 * lisp.h (toplevel): Add two notices to the comment about
136 defining a new Lisp data type.
137 * print.c (print_object): If Lisp_Save_Value object's pointer
138 is the address of a memory area containing Lisp_Objects, try
140 * alloc.c (valid_lisp_object_p): Adjust comment.
142 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
144 * keyboard.c (record_asynch_buffer_change): Initialize an event
145 only if it's really needed.
146 * frame.h (enum output_method): Remove output_mac member since
147 it's a leftover from the deleted code.
148 * frame.c (Fframep): Adjust user here ...
149 * terminal.c (Fterminal_live_p): ... and here.
150 * coding.c (Qmac): Now here because it's only used to denote
151 end-of-line encoding type.
152 (syms_of_coding): DEFSYM it.
153 * frame.h (Qmac): Remove duplicated declaration.
155 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
157 * window.c (select_window_1): Now static, since it's used only here.
159 2012-12-25 Eli Zaretskii <eliz@gnu.org>
161 * window.c (window_body_cols): Subtract display margins from the
162 window body width on TTYs as well. See
163 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
164 for the original report.
166 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
168 * xdisp.c (redisplay_window): Remove inner local variable
169 because the outer shadowed one has the same meaning.
170 * xterm.h (struct x_output): Remove toolbar_detached member since it's
172 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
173 (xg_create_tool_bar): Adjust users.
175 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
177 * buffer.h (BUF_COMPACT): New macro to follow the common style.
178 * buffer.c (Fget_buffer_create): Use it to set compact field of
179 struct buffer_text to avoid accessing an uninitialized value
180 when compact_buffer is called for the first time.
181 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
182 (Fset_buffer_modified_p): Use buffer_window_count to check
183 whether the buffer is displayed in some window.
184 * xdisp.c (message_dolog): Likewise.
186 2012-12-23 Eli Zaretskii <eliz@gnu.org>
188 * w32.c (acl_set_file): If setting the file security descriptor
189 fails, and the new DACL is identical to the existing one, silently
190 return success. This fixes problems for users backing up their
191 own files without having the necessary privileges for setting
192 security descriptors.
194 * w32proc.c (reader_thread): Do not index fd_info[] with negative
196 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
197 after WaitForSingleObject returns normally. This expedites reader
198 thread shutdown when delete_child triggers it.
199 (reap_subprocess): More accurate commentary for why we call
200 delete_child only when cp->fd is negative.
202 * w32.c (sys_close): Do not call delete_child on a subprocess
203 whose handle is not yet closed. Instead, set its file descriptor
204 to a negative value, so that reap_subprocess will call
205 delete_child on that subprocess when its SIGCHLD arrives. This
206 avoids closing handles used for communications between sys_select
207 and reader_thread, which doesn't give sys_select a chance to
208 notice that the process exited and invoke the SIGCHLD handler for
211 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
213 * nsfns.m (Fns_do_applescript): Run event loop until script has
214 been executed (Bug#12969).
215 (ns_run_ascript): Chech as_script for nil, set to nil after
218 2012-12-22 Martin Rudalics <rudalics@gmx.at>
220 * window.c (Fselect_window): Reword doc-string (Bug#13248).
222 2012-12-22 Eli Zaretskii <eliz@gnu.org>
224 * w32term.c (w32fullscreen_hook): New function.
225 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
227 2012-12-21 Eli Zaretskii <eliz@gnu.org>
229 * fileio.c (Finsert_file_contents): Doc fix.
231 * w32proc.c (new_child, delete_child, find_child_pid): For a
232 subprocess, consider its slot being in use as long as its process
233 handle (procinfo.hProcess) is not NULL. This avoids reusing the
234 slot when a new process is started immediately after killing
235 another one, without waiting enough time for the first process to
236 be reaped and resources allocated for it be orderly freed.
238 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
240 2012-12-21 Chong Yidong <cyd@gnu.org>
242 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
244 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
246 2012-12-21 Eli Zaretskii <eliz@gnu.org>
248 * w32.c (get_name_and_id): Always pass NULL as the first argument
249 of lookup_account_sid. Avoids crashes with UNC file names that
250 refer to DFS domains, not to specific machine names. (Bug#12621)
251 Remove now unused argument FNAME; all callers changed.
252 (get_file_owner_and_group): Remove now unused argument FNAME; all
255 2012-12-21 Chong Yidong <cyd@gnu.org>
257 * editfns.c (Finsert_char): Since read-char-by-name now signals an
258 error for invalid chars, don't check for a nil return value.
260 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
262 Avoid calls to CHAR_TO_BYTE if byte position is known.
263 * editfns.c (make_buffer_string_both): Use move_gap_both.
264 (Fbuffer_string): Use make_buffer_string_both.
265 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
267 (buf_bytepos_to_charpos): Likewise.
268 (charpos_to_bytepos): Remove.
269 * fileio.c (Finsert_file_contents): Use move_gap_both.
270 * search.c (Freplace_match): Likewise.
271 * process.c (process_send_region): Likewise. Use convenient
272 names for byte positions.
273 * lisp.h (charpos_to_bytepos): Remove prototype.
274 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
275 * insdel.c (move_gap): Likewise.
277 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
279 * xdisp.c (redisplay_internal): Remove now-unused local.
281 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
283 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
284 (redisplay_internal): Don't bother selecting the frame to get the
285 proper value of frame-local variables (bug#13225).
287 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
289 * textprop.c (set_text_properties_1): Do not allow NULL interval.
290 Rename 4th argument since it may be buffer or string. Adjust comment.
291 * intervals.c (graft_intervals_info_buffer): Find an interval here.
293 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
295 * coding.c (Fdetect_coding_region): Do not check start and end with
296 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
297 (code_convert_region): Likewise.
299 2012-12-18 Eli Zaretskii <eliz@gnu.org>
301 * w32.c (acl_get_file, acl_set_file): Run the file name through
302 map_w32_filename, and resolve any symlinks in the file name, like
304 (acl_set_file): Call revert_to_self, if any privileges were
307 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
309 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
310 ($(BLD)/w32.$(O)): Update dependencies.
312 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
314 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
315 propagate redisplay's scrolling (if any) to the right window.
316 (redisplay_internal): Use ensure_selected_frame.
317 (display_mode_lines): Complete last fix.
318 * window.c (select_window_1): New func, extracted from select_window.
319 (select_window): Use it.
320 * window.h (select_window_1): Declare.
322 2012-12-17 Eli Zaretskii <eliz@gnu.org>
324 Emulate Posix ACL APIs on MS-Windows.
325 * w32.c: Include sddl.h and sys/acl.h.
326 (SDDL_REVISION_1): Define if not already defined.
327 (g_b_init_get_security_descriptor_dacl)
328 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)

338 (get_security_descriptor_group): Set errno to ENOTSUP.
339 (set_file_security, get_security_descriptor_dacl)
340 (is_valid_security_descriptor, convert_sd_to_sddl)
341 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
342 (acl_free, acl_get_file, acl_set_file): New functions.
344 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
346 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
348 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
349 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
350 for some of that bug's symptoms can now cause Emacs to abort.
351 Remove the workaround.
352 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
353 The bug that caused SIGCHLD to get lost has been fixed, and the
354 workaround for it can now cause Emacs to abort.
356 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
358 * sysdep.c (emacs_abort): Bump backtrace size to 40.
359 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
360 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
362 2012-12-16 Romain Francoise <romain@orebokech.com>
364 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
365 (Fcopy_file): Change last arg to `preserve_extended_attributes'
366 and copy ACL entries of file in addition to SELinux context if set.
367 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
369 * Makefile.in (LIBACL_LIBS): New macro.
372 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
374 * fileio.c (internal_delete_file): Use bool for boolean.
376 2012-12-15 Eli Zaretskii <eliz@gnu.org>
378 Fix bug #13079 on MS-Windows with temp files not being deleted.
379 * w32.h (_child_process): New members input_file and
381 (register_child): First argument is now pid_t.
382 (record_infile, record_pending_deletion): New prototypes.
384 * w32proc.c (new_child): Initialize input_file and
385 pending_deletion members of the child.
386 (delete_child): Delete the child's temporary input file, if any,
387 that is pending deletion.
388 (register_child): First argument is now pid_t.
389 (record_infile, record_pending_deletion): New functions.
390 (reap_subprocess): Fix a typo in DebPrint string.
391 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
393 * fileio.c (internal_delete_file): Return an int again: non-zero
394 if delete-file succeeds, zero otherwise.
396 * lisp.h (internal_delete_file): Adjust prototype.
398 * callproc.c (Fcall_process): Don't overwrite infile with result
400 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
401 asynchronous subprocess, record the name of the input file name,
403 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
404 delete the file, record it as pending deletion when the subprocess
407 2012-12-14 Eli Zaretskii <eliz@gnu.org>
409 * editfns.c [HAVE_PWD_H]: Include grp.h.
411 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
413 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
415 Fix permissions bugs with setgid directories etc. (Bug#13125)
416 * dired.c (Ffile_attributes): Return t as the 9th attribute,
417 to mark it as a placeholder. The old value was often wrong.
418 The only user of this attribute has been changed to use
419 file-ownership-preserved-p instead, with its new group arg.
420 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
422 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

425 Keep selected_window and selected_frame in sync.
427 2012-12-14 Eli Zaretskii <eliz@gnu.org>
429 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
430 try to get accurate owner and group information from NT file
431 security APIs. This is to make most callers of 'stat' and
432 'lstat', which don't need that information, much faster.
434 * dired.c (Ffile_attributes) [WINDOWSNT]:
435 Set w32_stat_get_owner_group to a non-zero value, to request accurate
436 owner and group information from 'lstat'.
438 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
440 * fileio.c (Finsert_file_contents): Don't put tail into head area,
441 as that confuses set-auto-coding, so insist on the head-read
442 returning the full 1024 bytes. Let lseek compute the tail offset;
443 less work for us. Do not ignore I/O errors when reading the tail.
445 * xdisp.c: Minor style fixes.
446 (init_iterator): Hoist assignment out of if-expression.
447 (markpos_of_region): Callers now test for sign, not for -1.
449 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
451 Minor redisplay optimization when the region length is zero.
452 * xdisp.c (markpos_of_region): New function.
453 (init_iterator): Do not highlight the region of zero length.
454 (redisplay_window): Check whether the region is of non-zero length.
455 (try_cursor_movement): Allow if the region length is zero.
456 (try_window_reusing_current_matrix, try_window_id): Likewise.
458 2012-12-13 Eli Zaretskii <eliz@gnu.org>
460 * search.c (search_buffer): Check the inverse translations of each
461 character in pattern when the buffer being searched is unibyte.
464 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
466 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
467 files, fixing a regression from 24.2.
468 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
470 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
472 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
473 fstat shouldn't fail, and if it does fail copy-file should not proceed.
474 Remove unnecessary S_ISLNK test, as (contra the comments) this
475 function can't copy symlinks. Improve quality of error message
476 when attempting to copy files that are neither regular files nor
479 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
481 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.

483 * window.c (Frecenter):
484 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
485 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
487 2012-12-12 Daniel Colascione <dancol@dancol.org>
489 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
490 the dumped Emacs is not a sparse file, greatly improving Cygwin
491 "make bootstrap" performance.
493 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
495 * inotify.c (inotify_callback): Generate an Emacs event for every
496 incoming inotify event.
498 2012-12-11 Eli Zaretskii <eliz@gnu.org>
500 * xdisp.c (handle_face_prop): Fix logic of computing
501 it->start_of_box_run_p.

507 (append_stretch_glyph, append_glyphless_glyph): Reverse the
508 left_box_line_p and right_box_line_p flags of the glyph for R2L
509 glyph rows. (Bug#13011)

559 (hinst): Remove unneeded extern declaration.
560 (_start): Remove initialization of above variables; remove
561 initialization of hinst, as cache_system_info now does that.

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

703 * w32.c (unsetenv): Return 0 if the input string is too long.
705 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>

722 no longer needed here.
723 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
724 Move to inside set_time_zone_rule; they don't need file scope any more.
725 (set_time_zone_rule): Maintain the TZ=value string separately.
726 (syms_of_editfns): Don't initialize initial_tz;
727 init_editfns now does it.
728 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
729 * lisp.h (xputenv): New decl.
731 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

752 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
753 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
754 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.

756 (record_child_status_change, handle_child_signal, deliver_child_signal)

775 This will cause a production Emacs to dump core instead of
778 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
780 * frame.c (make_frame): Do not set window's buffer to t.
781 * window.c (Fsplit_window_internal): Likewise. Previously it was
782 used to indicate that the window is being set up. Now we use
783 set_window_buffer for all new windows, so the condition in ...
784 (Fset_window_buffer): ... is always true and can be removed.
786 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
788 Convenient macro to check whether the buffer is hidden.
789 * buffer.h (BUFFER_HIDDEN_P): New macro.

796 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
797 if the child process is still running. Instead, exit the wait
798 loop and return zero. (Bug#13086)

813 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
815 Fix a recently-introduced delete-process race condition.
816 * callproc.c, process.h (record_kill_process):
817 New function, containing part of the old call_process_kill.
818 (call_process_kill): Use it.
819 This does not change call_process_kill's behavior.
820 * process.c (Fdelete_process): Use record_kill_process to fix a
821 race condition that could cause Emacs to lose track of a child.
823 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
825 Avoid code duplication between prev_frame and next_frame.
826 * frame.c (candidate_frame): New function. Add comment.
827 (prev_frame, next_frame): Use it. Adjust comment.
829 2012-12-06 Eli Zaretskii <eliz@gnu.org>
831 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
832 fails, signal an error instead of continuing with an empty
834 Encode expanded temp file pattern before passing it to mkstemp or
837 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
838 Encode the file name before passing it to dostounix_filename, in
839 case it will downcase it (under w32-downcase-file-names).
842 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
844 Minor call-process cleanups.
845 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
846 at the same time as other platforms, to simplify analysis.
847 No need for fd0_volatile since we have synch_process_fd.
848 Avoid needless emacs_close; arg is always negative.
850 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
852 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
855 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
857 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
858 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
859 and mouse_face_hidden members to a bitfields.
860 * frame.h (struct frame): Remove set-but-not-used space_width member.
861 (FRAME_SPACE_WIDTH): Remove.

864 member. Adjust users. Convert term_initted, delete_in_insert_mode,
865 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
866 members to a bitfields.
868 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
870 Don't let call-process be a zombie factory (Bug#12980).
871 Fixing this bug required some cleanup of the signal-handling code.
872 As a side effect, this change also fixes a longstanding rare race
873 condition whereby Emacs could mistakenly kill unrelated processes,
874 and it fixes a bug where a second C-g does not kill a recalcitrant
875 synchronous process in GNU/Linux and similar platforms.
876 The patch should also fix the last vestiges of Bug#9488,
877 a bug which has mostly been fixed on the trunk by other changes.
878 * callproc.c, process.h (synch_process_alive, synch_process_death)
879 (synch_process_termsig, sync_process_retcode):
880 Remove. All uses removed, to simplify analysis and so that
881 less consing is done inside critical sections.
882 * callproc.c (call_process_exited): Remove. All uses replaced
883 with !synch_process_pid.
884 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
885 These take the role of what used to be in unwind-protect arg.
887 (block_child_signal, unblock_child_signal):
888 New functions, to avoid races that could kill innocent-victim processes.
889 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
890 (call_process_kill): Record killed processes as deleted, so that
891 zombies do not clutter up the system. Do this inside a critical
892 section, to avoid a race that would allow the clutter.
893 (call_process_cleanup): Fix code so that the second C-g works again
894 on common platforms such as GNU/Linux.
895 (Fcall_process): Create the child process in a critical section,
896 to fix a race condition. If creating an asynchronous process,
897 record it as deleted so that zombies do not clutter up the system.
898 Do unwind-protect for WINDOWSNT too, as that's simpler in the
899 light of these changes. Omit unnecessary call to emacs_close
900 before failure, as the unwind-protect code does that.
901 * callproc.c (call_process_cleanup):
902 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
903 * process.c (record_deleted_pid): New function, containing
904 code refactored out of Fdelete_process.
905 (Fdelete_process): Use it.
906 (process_status_retrieved): Remove. All callers changed to use
908 (record_child_status_change): Remove, folding its contents into ...
909 (handle_child_signal): ... this signal handler. Now, this
910 function is purely a handler for SIGCHLD, and is not called after
911 a synchronous waitpid returns; the synchronous code is moved to
912 wait_for_termination. There is no need to worry about reaping
913 more than one child now.
914 * sysdep.c (get_child_status, child_status_changed): New functions.
915 (wait_for_termination): Now takes int * status and bool
916 interruptible arguments, too. Do not record child status change;
917 that's now the caller's responsibility. All callers changed.
918 Reimplement in terms of get_child_status.
919 (wait_for_termination_1, interruptible_wait_for_termination):
920 Remove. All callers changed to use wait_for_termination.
921 * syswait.h: Include <stdbool.h>, for bool.
922 (record_child_status_change, interruptible_wait_for_termination):
924 (record_deleted_pid, child_status_changed): New decls.
925 (wait_for_termination): Adjust to API changes noted above.
927 * bytecode.c, lisp.h (Qbytecode): Remove.
928 No longer needed after 2012-11-20 interactive-p changes.
930 2012-12-03 Eli Zaretskii <eliz@gnu.org>
932 * xdisp.c (redisplay_window): If the cursor is visible, but inside
933 the scroll margin, move point outside the margin. (Bug#13055)
935 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
937 * gtkutil.c (my_log_handler): New function.
938 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
940 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
942 * lisp.h (modify_region): Rename to...
943 (modify_region_1): ...new prototype.
944 * textprop.c (modify_region): Now static. Adjust users.
945 * insdel.c (modify_region): Rename to...
946 (modify_region_1): ...new function to work with current buffer.
947 Adjust comment and users. Use true and false for booleans.
949 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
951 * alloc.c (free_save_value): New function.
952 (safe_alloca_unwind): Use it.
953 * lisp.h (free_save_value): New prototype.
954 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
956 (save_excursion_restore): Adjust to match saved data structure.
957 Use free_save_value to offload some work from GC. Drop obsolete
960 2012-12-03 Chong Yidong <cyd@gnu.org>
962 * fileio.c (Vauto_save_list_file_name): Doc fix.
964 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>

975 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
978 2012-12-03 Glenn Morris <rgm@gnu.org>

984 Fix xpalloc confusion after memory is exhausted.
985 * alloc.c (xpalloc): Comment fix.
986 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
987 and signals an error, do not clear charset_table_size, as
988 charset_table is still valid.
989 * doprnt.c (evxprintf): Clear *BUF after freeing it.
991 Use execve to avoid need to munge environ (Bug#13054).
992 * callproc.c (Fcall_process):
993 * process.c (create_process):
994 Don't save and restore environ; no longer needed.
995 * callproc.c (child_setup):
996 Use execve, not execvp, to preserve environ.
998 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1000 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1002 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1004 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1005 display for sliced images (Bug#10500).
1007 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1009 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1011 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1012 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1014 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1016 * xdisp.c (window_outdated): Remove eassert since it hits
1017 some suspicious corner cases (see Bug#13007 and Bug#13012).
1018 (mode_line_update_needed): New function.
1019 (redisplay_internal, redisplay_window): Use it.
1020 (ensure_selected_frame): New function.
1021 (redisplay_internal, unwind_redisplay): Use it.
1022 (redisplay_internal): Move comment about buffer_shared...
1023 (buffer_shared_and_changed): ...near to its real use.
1025 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1027 * callproc.c (Fcall_process): Don't misreport vfork failure.
1029 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1031 * callproc.c (Fcall_process): Fix vfork portability problems.
1032 Do not assume that fd[0], count, filefd, and save_environ survive
1033 vfork. Fix bug whereby wrong errno value could be reported for
1034 pipe failure. Some minor cleanups, too, as follows. Move buf and
1035 bufsize to the context where they're needed. Change new_argv to
1036 be of type char **, as this is more convenient and avoids casts.
1037 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1038 Now local constants, not macros.
1040 2012-11-18 Kenichi Handa <handa@gnu.org>
1042 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1043 for the variable "f".
1045 2012-11-13 Kenichi Handa <handa@gnu.org>
1047 * font.c (font_unparse_xlfd): Exclude special characters from the
1048 generating XLFD name.
1050 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1052 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

1054 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1056 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1060 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1061 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
1062 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
1063 * lread.c (readbyte_from_file): Assume EINTR is defined.
1064 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1065 Assume EIO and EAGAIN are defined.
1066 * unexcoff.c (write_segment): Assume EFAULT is defined.
1068 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1070 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1073 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1074 highlighting on the frame was cleared. Prevents assertion
1075 violations when repeatedly clicking on the "Top" link of the
1076 "bread-crumbs" in Info buffers.
1078 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

1085 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1086 were always defined.
1088 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1090 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1091 between bpos_covered and bpos_max. This fixes cursor display when
1092 several display strings follow each other.
1094 * .gdbinit (pgx): If the glyph's object is a string, display the
1095 pointer to string data, rather than the value of the string object
1096 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1098 * indent.c (Fvertical_motion): If the starting position is covered
1099 by a display string, return to one position before that, to avoid
1100 overshooting it inside move_it_to. (Bug#12930)
1102 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1104 * frame.h (struct frame): Remove display_preempted member
1105 since all users are dead long ago.
1106 * nsterm.h (struct x_output): Use the only dummy member.
1107 * w32menu.c (pending_menu_activation): Remove since not
1109 (set_frame_menubar): Adjust user.
1110 * w32term.h (struct x_output): Drop outdated #if 0 code.
1111 (struct w32_output): Use bitfields for explicit_parent,
1112 asked_for_visible and menubar_active members.
1113 Drop unused pending_menu_activation member.
1114 * xterm.h (struct x_output): Drop outdated #if 0 code.
1115 Use bitfields for explicit_parent, asked_for_visible,
1116 has_been_visible and net_wm_state_hidden_seen members.
1118 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1120 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1121 of a literal "/". (Bug#12955)
1122 (gl-stamp): Invoke fc.exe directly, not through cmd.
1124 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1126 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1127 * dired.c: Assume HAVE_DIRENT_H.
1128 (NAMLEN): Remove, replacing with ...
1129 (dirent_namelen): New function. All uses changed. Use the GNU macro
1130 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1131 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1132 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1133 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1135 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1136 * ndir.h: Rename to ../nt/inc/dirent.h.
1137 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1138 Do not include <dirent.h>; no longer needed.
1139 * w32.c: Include <dirent.h> rather than "ndir.h".
1141 2012-11-23 Chong Yidong <cyd@gnu.org>
1143 * xftfont.c (xftfont_open): Remove duplicate assignment.
1145 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1147 * alloc.c (Fgarbage_collect): Unblock input after clearing
1148 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1149 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1150 * msdos.c (IT_frame_up_to_date): Use it here...
1151 * w32term.c (w32_frame_up_to_date): ...here...
1152 * xterm.c (XTframe_up_to_date): ...and here...
1153 * nsterm.m (ns_frame_up_to_date): ...but not here.
1154 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1156 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1157 Do not check whether GC is in progress.
1159 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1161 * xdisp.c (window_buffer_changed): New function.
1162 (update_menu_bar, update_tool_bar): Use it to
1163 simplify large 'if' statements.
1164 (redisplay_internal): Generalize commonly used
1165 'tail' and 'frame' local variables.
1167 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1169 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1170 with Windows system header.
1172 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1174 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1175 * alloc.c: Assume unistd.h exists.
1176 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1177 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1178 (getwd) [USG]: Remove; no longer needed.
1179 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1180 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1181 * w32.h (getcwd): Remove decl.
1183 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1185 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1186 Make it set selected_window as well.
1187 (update_tool_bar): Use it.
1189 2012-11-21 Ken Brown <kbrown@cornell.edu>
1191 * emacs.c (main): Set the G_SLICE environment variable for all
1192 Cygwin builds, not just GTK builds. See
1193 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1195 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1197 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1198 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1199 Define for the MSVC compiler.
1201 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1203 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1204 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1205 dostounix_filename. Prevents crashes down the road, because
1206 dostounix_filename assumes it gets a unibyte string.
1207 Reported by Michel de Ruiter <michel@sentient.nl>, see
1208 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1210 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1214 * lread.c (init_obarray): Set `function' fields to Qnil.
1215 * eval.c (Fcommandp): Ignore Qunbound.
1216 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1217 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1218 Test NILP rather than Qunbound.
1219 (Ffmakunbound): Set to Qnil.
1220 (Fsymbol_function): Never signal an error.
1221 (Finteractive_form): Ignore Qunbound.
1223 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1225 * eval.c (interactive_p): Remove no-longer-used decl.
1227 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1229 * xdisp.c (buffer_shared): Adjust comment.
1230 (buffer_shared_and_changed): New function.
1231 (prepare_menu_bars, redisplay_internal): Use it to
1232 decide whether all windows or frames should be updated.
1233 (window_outdated): New function.
1234 (text_outside_line_unchanged_p, redisplay_window): Use it.
1235 (redisplay_internal): Likewise. Fix indentation.
1237 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1239 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1240 (syms_of_eval): Remove corresponding defsubr.
1241 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1243 2012-11-19 Daniel Colascione <dancol@dancol.org>
1245 * w32fns.c (Fx_file_dialog):
1246 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1247 cygwin_convert_file_name*.
1249 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1250 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1252 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1254 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1256 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1258 * w32select.c: Include w32common.h before w32term.h, so that
1259 windows.h gets included before w32term.h uses some of its
1260 features, see below.
1262 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1264 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1266 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1268 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1270 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1271 (ns_select): Return at once if events are held (Bug#12834).
1273 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1275 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1276 Needed following 2012-10-20 change. (Bug#12902)
1278 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1280 * w32proc.c (waitpid): Remove unused label get_result.
1282 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1284 * makefile.w32-in (SYSWAIT_H): New macro.
1285 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1286 ($(BLD)/sysdep.$(O)): Update dependencies.
1288 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1290 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1291 * callproc.c (relocate_fd): Assume F_DUPFD.
1292 * emacs.c, term.c (O_RDWR): Remove.
1293 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1294 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1295 * nsterm.m: Assume <fcntl.h> exists.
1296 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1297 (create_pty, Fmake_network_process, server_accept_connection)
1298 (wait_reading_process_output, init_process_emacs):
1300 (wait_reading_process_output): Put in a special case for WINDOWSNT
1301 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1302 It's not clear this is needed, but it's a more-conservative change.
1303 (create_process): Assume FD_CLOEXEC.
1304 (create_process, create_pty): Assume O_NOCTTY.
1305 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1306 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1307 Omit if not DOS_NT, since F_GETFL is not defined there.
1308 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1309 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1311 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1312 lack it, since gnulib guarantees this.
1313 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1315 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1317 * w32.c (faccessat): Pretend that directories have the execute bit
1318 set. Emacs expects that, e.g., in files.el:cd-absolute.
1320 * w32proc.c (create_child): Don't clip the PID of the child
1321 process to fit into an Emacs integer, as this is no longer a
1323 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1324 reaping only the process specified by PID argument, if that is
1325 positive. Use PID instead of dead_child to know which process to
1326 reap. Wait for the child to die only if WNOHANG is not in
1328 (sys_select): Don't set dead_child.
1330 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1331 as it is no longer needed.
1333 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1335 (record_child_status_change): Remove the setting of
1336 record_at_most_one_child for the !WNOHANG case.
1338 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1340 Fix problems in ns port found by static checking.
1341 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1342 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1343 not to process group.
1344 (ns_select): Use emacs_write, not write, as that's more robust
1345 in the presence of signals.
1346 (fd_handler:): Check for read errors.
1348 2012-11-16 Glenn Morris <rgm@gnu.org>
1350 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1352 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1354 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1356 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1358 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1359 use the same value of thread handle.
1360 (start_timer_thread): If the timer thread exited (due to error),
1361 clean up by closing the two handles it used. Duplicate the caller
1362 thread's handle here, so it gets duplicated only once, when
1363 launching the timer thread. Set priority of the timer thread, not
1365 (getitimer): Don't duplicate the caller thread's handle here.
1368 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1370 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1373 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1375 Remove no-longer-used pty_max_bytes variable.
1376 * process.c (pty_max_bytes): Remove; unused.
1377 (send_process): Do not set it.
1379 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1381 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1382 Update dependencies.
1384 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1386 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1387 This follows up on the 2012-09-29 patch that removed indirection
1388 for the 'function' field. Reported by Sergey Vinokurov in
1389 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1391 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1393 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1394 different name, as the MS runtime does not have such a function,
1395 and probably never will.) All callers changed. Ignore DIRFD
1396 value if PATH is an absolute file name, to match Posix spec
1397 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1400 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1402 * xdisp.c (echo_area_display, redisplay_internal):
1403 Omit redundant check whether frame_garbaged is set.
1405 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1407 Use faccessat, not access, when checking file permissions (Bug#12632).
1408 This fixes a bug that has been present in Emacs since its creation.
1409 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1410 which must set some sort of record. (Torek's bug report was against
1411 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1412 same common flaw.) See Torek's Usenet posting
1413 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1414 Posted: Fri Apr 8 14:18:56 1983.
1415 * Makefile.in (LIB_EACCESS): New macro.
1417 * callproc.c (init_callproc):
1418 * charset.c (init_charset):
1419 * fileio.c (check_existing, check_executable, check_writable)
1421 * lread.c (openp, load_path_check):
1422 * process.c (allocate_pty):
1424 Use effective UID when checking permissions, not real UID.
1425 * callproc.c (init_callproc):
1426 * charset.c (init_charset):
1427 * lread.c (load_path_check, init_lread):
1428 Test whether directories are accessible, not merely whether they exist.
1429 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1430 * fileio.c (check_existing, check_executable, check_writable)
1432 Use symbolic names instead of integers for the flags, as they're
1434 (check_writable): New arg AMODE. All uses changed.
1435 Set errno on failure.
1436 (Ffile_readable_p): Use faccessat, not stat + open + close.
1437 (Ffile_writable_p): No need to call check_existing + check_writable.
1438 Just call check_writable and then look at errno. This saves a syscall.
1439 dir should never be nil; replace an unnecessary runtime check
1440 with an eassert. When checking the parent directory of a nonexistent
1441 file, check that the directory is searchable as well as writable, as
1442 we can't create files in unsearchable directories.
1443 (file_directory_p): New function, which uses 'stat' on most platforms
1444 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1445 (Ffile_directory_p, Fset_file_times): Use it.
1446 (file_accessible_directory_p): New function, which uses a single
1447 syscall for efficiency.
1448 (Ffile_accessible_directory_p): Use it.
1449 * xrdb.c (file_p): Use file_directory_p.
1450 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1451 * lread.c (openp): When opening a file, use fstat rather than
1452 stat, as that avoids a permissions race. When not opening a file,
1453 use file_directory_p rather than stat.
1454 (dir_warning): First arg is now a usage string, not a format.
1455 Use errno. All uses changed.
1456 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1457 that merely introduced a race.
1458 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1459 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1460 and similarly for the other O_* flags.
1461 * w32.c (sys_faccessat): Rename from sys_access and switch to
1462 faccessat's API. All uses changed.
1463 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1464 (magic_db): Rename from magic_file_p.
1465 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1466 char *, so that we don't have to test for file existence
1467 separately from opening the file for reading. This removes a race
1468 fixes a permission-checking problem, and simplifies the code.
1470 (file_p): Remove; no longer needed.
1472 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1474 Omit glyphs initialization at startup.

1485 passed to pint2str and pint2hrstr to be at most the size of the
1486 frame's decode_mode_spec_buffer. This avoids crashes with very
1487 large values of FIELD_WIDTH argument to decode_mode_spec.
1490 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1492 Fix a race with verify-visited-file-modtime (Bug#12863).
1493 Since at least 1991 Emacs has ignored an mtime difference of no
1494 more than one second, but my guess is that this was to work around
1495 file system bugs that were fixed long ago. Since the race is
1496 causing problems now, let's remove that code.
1497 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1498 whose time stamp is off by no more than a second. Insist that the
1499 file time stamps match exactly.
1501 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1503 * frame.h (struct frame): Convert external_tool_bar member to
1504 1-bit unsigned bitfield.

1506 all users are long dead. Adjust comment on mouse_position_hook.
1508 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1510 Simplify by using FOR_EACH_FRAME here and there.
1511 * frame.c (next_frame, prev_frame, other_visible_frames)

1518 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1519 * xmenu.c (menubar_id_to_frame): Likewise.
1520 * xselect.c (frame_for_x_selection): Likewise.
1521 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1522 (x_window_to_menu_bar): Likewise.
1523 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1525 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1527 * data.c (Qdefalias_fset_function): Now static.
1529 Another tweak to vectorlike_header change.
1530 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1531 Remove, and replace all uses with ...
1532 (next_in_free_list, set_next_in_free_list):
1533 New functions, which respect C's aliasing rules better.
1535 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1537 * window.c (list4i): Rename from 'quad'. All uses changed.
1538 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1540 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1542 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1543 warning about mixing declarations and code in ISO C90.
1545 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1547 * window.c (Fsplit_window_internal): Set combination limit of
1548 new parent window to t iff Vwindow_combination_limit is t;
1549 fixing a regression introduced with the change from 2012-09-22.
1550 (Fset_window_combination_limit): Fix doc-string.
1552 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1554 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1555 amount when the scroll margins are too large. When scrolling
1556 backwards in the buffer, give up if cannot reach point or the
1557 scroll margin within a reasonable number of screen lines.
1558 Fixes point position in window under scroll-up/down-aggressively when
1559 point is positioned many lines beyond the window top/bottom.
1562 * ralloc.c (relinquish): If real_morecore fails to return memory
1563 to the system, don't crash; instead, leave the last heap
1564 unchanged and return. (Bug#12774)
1566 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1568 * lisp.h (AUTOLOADP): New macro.

1573 (Finteractive_form): Simplify.
1574 (Fquo): Don't insist on having at least 2 arguments.
1575 (Qdefalias_fset_function): New var.
1577 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1579 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

1585 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1587 Fix recently introduced crash on MS-Windows (Bug#12839).
1588 * w32term.h (struct scroll_bar): Use convenient header.
1589 (SCROLL_BAR_VEC_SIZE): Remove.
1590 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1592 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1594 Tweak last vectorlike_header change.
1595 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1596 vectorlike object on the free list. This is introduced to avoid
1597 some (but not all) pointer casting and aliasing problems, see
1598 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1599 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

1603 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1605 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1606 been removed, so remove them here also.
1608 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1610 * doc.c (Fdocumentation): Handle new property
1611 dynamic-docstring-function to replace the old ad-advice-info.
1613 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1615 * fns.c (Qeql, hashtest_eq): Now static.
1617 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1619 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1620 * fns.c (hashfn_eq, hashfn_eql, sxhash):

1628 * lisp.h (sxhash_combine): New inline function, with the contents
1629 of the old SXHASH_COMBINE.

1631 special hash function containing a comparison that always yields 1.
1633 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1635 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1636 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1637 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1640 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1642 * image.c (xpm_make_color_table_h): Fix compiler error because
1643 make_hash_table changed.
1645 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1647 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1649 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1651 Use ad-hoc comparison function for the profiler's hash-tables.
1652 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1653 (make_log): Use them.
1654 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1655 call Fequal any more.

1664 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1665 (hash_lookup, hash_remove_from_table): Move assertion checking of
1666 hashfn result here. Check hash-equality before calling cmpfn.

1684 Shrink struct vectorlike_header to the only size field.
1685 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1687 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

1689 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1690 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1691 information from the vector header. Adjust comment.

1703 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1704 (Fmake_bool_vector): Likewise.
1705 (struct large_vector): New type to represent allocation unit for
1706 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1707 (large_vectors): Change type to struct large_vector.
1708 (allocate_vector_from_block): Simplify.
1709 (PSEUDOVECTOR_NBYTES): Replace with...

1715 (allocate_buffer): Use BUFFER_PVEC_INIT.
1716 (live_vector_p): Adjust to match large vector.
1717 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1718 * buffer.h (struct buffer): Add next member.
1719 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1721 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

1727 (xvecsize): New command.
1729 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1731 * keyboard.c (event_to_kboard): Do not dereference
1732 frame_or_window field of SELECTION_REQUEST_EVENT
1733 and SELECTION_CLEAR_EVENT events (Bug#12814).
1734 * xterm.h (struct selection_input_event): Adjust comment.
1736 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1738 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1739 such as Scroll Lock, if the respective keys are treated as
1740 function keys, not as modifiers. This avoids destroying non-ASCII
1741 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1743 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1745 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1747 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1749 Restore some duplicate definitions (Bug#12814).
1750 This undoes part of the 2012-11-03 changes. Some people build
1751 with plain -g rather than with -g3, and they need the duplicate
1752 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1753 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1754 Define as macros, as well as as enums or as constants.
1756 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1758 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1759 to keypad keys (Bug#12816).
1761 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1763 Minor adjustments of recently-changed frame functions.
1764 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1765 known to be a frame (we're in the FRAMEP branch).
1766 * lisp.h (Qframep): Remove decl. frame.h declares this.
1767 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1768 since they're meant for Lisp fixnum values.
1770 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1772 * window.c (Fwindow_combination_limit): Revert to the only
1773 required argument and adjust docstring as suggested in
1774 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1775 by Martin Rudalics <rudalics@gmx.at>.
1777 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

1807 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1808 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1809 (Fframe_face_alist): Use decode_live_frame.
1810 * xfns.c (check_x_frame): Likewise.
1812 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

1817 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1818 (Fwindow_line_height): Use it.
1819 (Fwindow_fringes): Use list3.
1820 (Fwindow_scroll_bars): Use list4.
1821 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1822 (Fwindow_combination_limit): Allow zero number of arguments.
1824 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1826 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1828 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1829 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1830 file descriptor 2 for standard error. (Bug#12805)
1832 2012-11-05 Chong Yidong <cyd@gnu.org>
1834 * process.c (wait_reading_process_output): Revert previous change.
1836 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1838 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1839 This removes code that has been obsolete since around 1990.
1840 * callproc.c (Fcall_process):
1842 * process.c (create_process):
1843 * term.c (dissociate_if_controlling_tty):
1844 Assume setsid exists.
1845 * callproc.c (child_setup): Assume setpgid exists and behaves as
1846 per POSIX.1-1988 or later.
1847 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1848 * emacs.c (shut_down_emacs):
1849 * sysdep.c (sys_suspend, init_foreground_group):
1850 Assume getpgrp behaves as per POSIX.1-1998 or later.
1851 * msdos.c (setpgrp): Remove.
1852 (tcgetpgrp, setpgid, setsid): New functions.
1853 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1854 * term.c (no_controlling_tty): Remove; unused.
1855 * w32proc.c (setpgrp): Remove.
1856 (setsid, tcgetpgrp): New functions.
1858 Simplify by assuming __fpending.
1859 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1860 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1861 Do not assume that __fpending's result fits in int.
1863 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1865 Remove EMACS_OUTQSIZE+sleep hack.
1866 * dispnew.c (update_frame_1): Remove hack for terminals slower
1867 than 2400 bps, which throttled Emacs by having it sleep.
1868 This code hasn't worked since at least 2007, when the multi-tty stuff
1869 was added, and anyway those old terminals are long dead.
1870 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1871 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1873 Fix data-loss with --version (Bug#9574).
1874 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1875 as we can't assume that emacs_strerror is initialized, and strerror
1876 is good enough here.
1877 (main): Invoke atexit earlier, to catch earlier instances of
1878 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1880 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1882 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1883 (keyDown): Remap keypad keys to X11 virtual key codes.
1885 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1887 Fix data-loss with --batch (Bug#9574).
1888 * emacs.c: Include <close-stream.h>.
1889 (close_output_streams): New function.
1890 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1891 and handles errors appropriately.
1892 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1895 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1896 The symptom is a diagnostic "GLib-WARNING **: In call to
1897 g_spawn_sync(), exit status of a child process was requested but
1898 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1899 waitpid(), so exit status can't be returned." The diagnostic
1900 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1901 The real bug is a race condition between Emacs and glib: Emacs
1902 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1903 so that glib can't find it. Work around the bug by invoking
1904 waitpid only on subprocesses that Emacs itself creates.
1905 * process.c (create_process, record_child_status_change):
1906 Don't use special value -1 in pid field, as the caller now must
1907 know the pid rather than having the callee infer it.
1908 The inference was sometimes incorrect anyway, due to another race.
1909 (create_process): Set new 'alive' member if child is created.
1910 (process_status_retrieved): New function.
1911 (record_child_status_change): Use it.
1912 Accept negative 1st argument, which means to wait for the
1913 processes that Emacs already knows about. Move special-case code
1914 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1915 processes that have already been waited for, by testing and
1916 clearing new 'alive' member.
1917 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1918 now does this internally.
1919 (handle_child_signal): Let record_child_status_change do all
1920 the work, since we do not want to reap all exited child processes,
1921 only the child processes that Emacs itself created.
1922 * process.h (Lisp_Process): New boolean member 'alive'.
1924 Omit duplicate definitions no longer needed with gcc -g3.
1925 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1926 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1927 Define only as macros. There's no longer any need to also define
1928 these symbols as enums or as constants, since we now assume
1929 gcc -g3 when debugging.
1931 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1933 * lisp.mk: Adjust comments to the fact that term/internal is now
1934 loaded from loadup.el.
1936 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1937 (msdos_fatal_signal): New function.
1938 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1941 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1942 for GCC versions before 4.
1943 (emacs_raise): Define to call msdos_fatal_signal.
1945 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1946 iterator when starting in the middle of a display or overlay
1949 2012-11-03 Chong Yidong <cyd@gnu.org>
1951 * process.c (wait_reading_process_output): Clean up the last
1954 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1956 * process.c (wait_reading_process_output): Avoid a race condition
1957 with SIGIO delivery (Bug#11536).
1959 2012-11-03 Chong Yidong <cyd@gnu.org>
1961 * buffer.c (cursor_type): Untabify docstring.
1963 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1965 * frame.h (struct frame): Drop can_have_scroll_bars member
1966 which is meaningless for a long time. Adjust comments.
1967 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1968 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1970 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1972 * window.c (decode_next_window_args): Update window arg after
1973 calling decode_live_window and so fix crash reported at
1974 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1975 by Juanma Barranquero <lekktu@gmail.com>.
1976 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1977 * font.c (Ffont_at): Likewise.
1979 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1981 * widget.c (resize_cb): New function.
1982 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1983 (EmacsFrameResize): Check if all is up to date before changing frame
1986 2012-11-02 Eli Zaretskii <eliz@gnu.org>

1990 (BACKTRACE_LIMIT_MAX): New macro.
1991 (w32_backtrace): New function.
1992 (emacs_abort): Use w32_backtrace when the user chooses not to
1993 attach a debugger. Update the text of the abort dialog.
1995 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1997 Window-related stuff cleanup here and there.
1998 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1999 Use decode_any_window.
2000 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2001 * xdisp.c (Fformat_mode_line): Likewise.
2002 * font.c (Ffont_at): Use decode_live_window.
2003 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2004 * window.c (decode_next_window_args): Likewise.
2005 (decode_any_window): Remove static.
2006 * window.h (decode_any_window): Add prototype.
2007 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2008 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2011 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2013 Remove pad from struct input_event.
2014 * termhooks.h (struct input_event): Remove padding field.
2016 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2017 member is never cons for a long time. Adjust comment.
2018 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2019 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2020 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2021 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2023 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2025 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2027 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2029 Fix crash when using Emacs as commit editor for git (Bug#12697).
2030 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2031 and it is configured in conf_post.h.
2032 (Fcall_process): Don't invoke both setsid and setpgid; the former
2033 is enough, if it exists.
2034 * callproc.c (Fcall_process, child_setup):
2035 * process.c (create_process): Use setpgid.
2036 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2038 * dispnew.c (init_display): Initialize the foreground group
2039 if we are running a tty display.
2040 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2041 * lisp.h (init_foreground_group): New decl.
2042 * sysdep.c (inherited_pgroup): New static var.
2043 (init_foreground_group, tcsetpgrp_without_stopping)
2044 (narrow_foreground_group, widen_foreground_group): New functions.
2045 (init_sys_modes): Narrow foreground group.
2046 (reset_sys_modes): Widen foreground group.
2048 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2050 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2052 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2054 * minibuf.c (read_minibuf): Restore current buffer since
2055 choose_minibuf_frame calling Fset_frame_selected_window may
2056 change it (Bug#12766).
2058 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2060 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2062 2012-10-30 Kenichi Handa <handa@gnu.org>
2064 * font.c (Ffont_at): If WINDOW is specified and it is not
2065 displaying the current buffer, signal an error.
2067 2012-10-29 Daniel Colascione <dancol@dancol.org>
2069 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2070 In preparation for fixing bug#12739, move these functions from
2073 * coding.h, coding.c: ... to here, and compile them only when
2074 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2075 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2077 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2079 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2080 (timer_loop, getitimer, setitimer): Use it instead of
2081 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2083 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2086 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2088 * nsterm.m (NO_APPDEFINED_DATA): New define.
2089 (last_appdefined_event_data): New variable
2090 (last_appdefined_event): Remove.
2091 (ns_select): Initialize t from last_appdefined_event_data instead
2092 of [last_appdefined_event data1].
2093 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2094 remove last_appdefined_event (Bug#12698).
2096 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2098 * frame.c (x_set_font): Catch internal error.
2100 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2102 Avoid overflow in w32 implementation of interval timers.
2103 When possible, for ITIMER_PROF count only times the main thread
2105 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2106 'volatile ULONGLONG' types. All the other data which was
2107 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2108 (GetThreadTimes_Proc): New typedef.
2109 (w32_get_timer_time): New function, returns a suitable time value
2111 (timer_loop): Enter critical section when accessing ULONGLONG
2112 values of the itimer_data struct, as these accesses are no longer
2113 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2114 Remove unused variable.
2115 (init_timers): Initialize s_pfn_Get_Thread_Times.
2116 (start_timer_thread): Don't assign itimer->caller_thread here.
2117 (getitimer): Assign itimer->caller_thread here.
2118 (setitimer): Always call getitimer to get the value of ticks_now.
2119 (sys_spawnve): Avoid compiler warning about format mismatch.
2121 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2123 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2124 mouse movement events if the menu bar is active. This avoids
2125 producing a busy "hour-glass" cursor by Windows if the mouse
2126 pointer is positioned over a tooltip shown for some menu item.
2128 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2130 Don't assume process IDs fit in int.
2131 * emacs.c (shut_down_emacs) [!DOS_NT]:
2132 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2133 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2134 Use pid_t, not int, to store process IDs, as 'int'
2135 is not wide enough on a few platforms (e.g., AIX and IRIX).
2137 2012-10-23 Kenichi Handa <handa@gnu.org>
2139 The following change is to make face-font-rescale-alist work
2140 correctly for non-ASCII fonts.
2142 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2143 (font_open_for_lface): Handle Vface_font_rescale_alist.
2145 2012-10-23 Chong Yidong <cyd@gnu.org>
2147 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2149 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

2158 2012-10-21 Glenn Morris <rgm@gnu.org>
2160 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2162 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2164 Port to OpenBSD 5.1.
2165 * frame.c (Fmouse_position, Fmouse_pixel_position):
2166 * xdisp.c (produce_stretch_glyph):
2167 Declare local vars only when they're needed.
2168 This is clearer and avoids a warning on OpenBSD about unused vars.
2169 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2170 This is safer, and avoids OpenBSD warnings about unused vars.
2171 * keyboard.c (record_menu_key): Remove unnecessary decl.
2172 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2173 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2174 as our definition clashes with OpenBSD's.
2175 * xfaces.c (load_face_colors, check_lface_attrs)
2176 (get_lface_attributes_no_remap, get_lface_attributes)
2177 (lface_fully_specified_p, x_supports_face_attributes_p)
2178 (tty_supports_face_attributes_p, face_fontset, realize_face)
2179 (realize_x_face, realize_tty_face):
2180 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2181 merely Lisp_Object *. This is more informative and avoids
2182 a warning on OpenBSD about accessing beyond an object's size.
2184 2012-10-20 Chong Yidong <cyd@gnu.org>
2186 * lread.c (Fload): Doc fix (Bug#12592).
2188 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2190 * font.c (Ffont_at): Fix previous change.
2192 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2194 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2195 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

2212 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2213 (staticpro): If we run out of staticpro slots, die with an
2214 informative error instead of just calling emacs_abort.
2216 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2218 Fix two flaws reported by Dmitry Antipov.
2219 * window.c (Ftemp_output_buffer_show): Remove.

2240 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
2241 (sys_link): Add prototypes.
2243 * w32.c: Include w32select.h.
2244 (sys_access, e_malloc, sys_select): Add prototypes.

2259 * cygw32.c (Fcygwin_convert_path_to_windows)
2260 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
2261 Lisp_Object values. (Bug#12661)
2263 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
2264 to Lisp_Object. (Bug#12661)

2336 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
2338 Fix some stat-related races.
2339 * fileio.c (Fwrite_region): Avoid race condition if a file is
2340 removed or renamed by some other process immediately after Emacs
2341 writes it but before Emacs stats it. Do not assume that stat (or
2343 * image.c (slurp_file): Resolve the file name with fopen + fstat
2344 rather than stat + fopen.

2362 is zero (Bug#12384).
2364 2012-10-12 Juanma Barranquero <lekktu@gmail.com>
2366 * makefile.w32-in ($(BLD)/w32select.$(O)): Update dependencies.
2368 2012-10-12 Eli Zaretskii <eliz@gnu.org>
2370 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
2372 * fileio.c (check_existing): New function.
2373 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
2374 instead of calling 'stat', when what's needed is to check whether
2375 a file exists. This avoids expensive system calls on MS-Windows.
2378 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
2380 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
2381 determine whether a file exists and is not a directory.
2383 * lisp.h (check_existing): Add prototype.
2385 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
2387 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.
2389 2012-10-12 Glenn Morris <rgm@gnu.org>

2416 (xmenu_show, xdialog_show):
2417 Use bool for booleans.
2418 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
2419 as it's not a predicate. All uses changed. Omit unnecessary
2422 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
2424 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.
2425 (save_excursion_restore): Do not restore mark if it was not saved.
2427 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
2429 * marker.c (cached_modiff): EMACS_INT, not int.
2431 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
2432 instead of having a wrong decl.
2433 * nsmenu.m (waiting_for_input): Remove wrong decl.
2435 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2437 keyboard.c, keymap.c: Use bool for booleans.

2468 Use bool for boolean.
2469 * keyboard.c (timers_run, swallow_events)
2470 (detect_input_pending_run_timers):
2471 * process.c (wait_reading_process_output):
2472 Use unsigned for counter where wraparound-on-overflow is desired,
2473 since unsigned is guaranteed to have that behavior and signed is not.
2474 (read_char): Use ptrdiff_t for string length.
2475 (get_input_pending): Remove first argument, since it was always
2476 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2477 and behave as if it had that value. Return new value of
2478 input_pending. All callers changed.
2479 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2480 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
2482 * keymap.c (push_key_description): Omit last arg, which was always 1.
2483 All callers changed.
2485 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
2487 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

2498 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2500 Clean out old termopts cruft.
2501 * termopts.h (flow_control, meta_key): Remove unused decls.
2502 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
2503 Don't include termopts.h.
2505 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
2507 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
2509 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2511 * commands.h (immediate_quit): Remove duplicate decl.
2513 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
2515 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
2517 (nsfont_open): Remove setting of Vfonts_in_cache.
2518 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
2520 2012-10-09 Eli Zaretskii <eliz@gnu.org>
2522 * w32fns.c (w32_last_error): Change the return value to DWORD, to
2523 match what GetLastError returns. Explain why the function is
2526 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2527 'is_tooltip_frame', to avoid confusion with its global namesake.
2529 2012-10-08 Daniel Colascione <dancol@dancol.org>
2531 * xdisp.c (start_hourglass): Call w32_note_current_window when
2532 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2533 build that caused Emacs to display the hourglass cursor forever.
2535 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2536 which is broken under remote desktop, calculate the number of
2537 colors available for a display based on the display's number of
2538 planes and number of bits per pixel per plane. (bug#10397).
2540 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2542 * nsfont.m (Vfonts_in_cache): New variable.
2543 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2544 are used. Add cached fonts to Vfonts_in_cache.
2545 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2547 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2549 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2551 (FONT_H): Define after FRAME_H.
2552 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2553 Update dependencies.
2555 * w32term.c: Remove leftover declaration of keyboard_codepage.
2557 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2559 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2560 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2561 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2562 (GLOBAL_SOURCES): Add cygw32.c.
2563 ($(BLD)/unexw32.$(O)):
2565 ($(BLD)/w32console.$(O)):
2566 ($(BLD)/w32fns.$(O)):
2567 ($(BLD)/w32heap.$(O)):
2568 ($(BLD)/w32menu.$(O)):
2569 ($(BLD)/w32proc.$(O)): Add w32common.h.
2571 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2573 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2575 2012-10-08 Daniel Colascione <dancol@dancol.org>
2577 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2578 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2579 accidental message numbering hole. Change other messages to
2582 * w32select.h (HAVE_W32SELECT): Remove.
2584 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2585 w32common.h instead of w32heap.h.
2587 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2588 (get_allocation_unit, get_processor_type, get_w32_major_version)
2589 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2590 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2591 (OS_NT, os_subtype, cache_system_info): Move declarations to
2594 * w32heap.c: Include w32common.h.
2595 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2596 (w32_minor_version, w32_build_number, w32_subtype):
2597 Remove duplicate definitions.
2599 * w32fns.c: Include w32common.h; include w32heap.h only in
2602 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2603 Use `report_file_error' instead of `error' in order to better
2604 inform users of what went wrong. Increase NTGUI_UNICODE file
2605 dialog box file name length to 32k, the maximum allowed by the NT
2608 * w32common.h: New file.
2609 (ROUND_UP, ROUND_DOWN, get_page_size)
2610 (get_allocation_unit, get_processor_type, get_w32_major_version)
2611 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2612 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2613 (OS_NT, os_subtype, cache_system_info): Move here.
2615 * unexw32.c, unexcw.c: Include w32common.h.
2617 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2618 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2619 to call syms_of_w32select.
2621 * cygw32.h: Remove obsolete EXFUN declarations.
2623 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2625 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2626 of w32inevt.o from SOME_MACHINE_OBJECTS.
2628 2012-10-08 Daniel Colascione <dancol@dancol.org>
2630 * image.c: Permanent fix for JPEG compilation issue --- limit
2631 jpeglib `boolean' redefinition to Cygwin builds.
2633 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2635 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2637 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2640 2012-10-08 Daniel Colascione <dancol@dancol.org>
2642 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2643 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2644 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2645 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2646 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2647 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2648 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2649 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2650 now a supported configuration.
2652 * Makefile.in: consolidate image variables into LIBIMAGE; add
2653 W32_OBJ and W32_LIBS. Compile new files.
2656 (_DebPrint) declare tracing facility for W32 debugging. We need
2657 to unify tracing later.
2659 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2660 unconditional use of W32 Unicode functions. Cygwin runs only on
2661 100% Unicode operating systems.
2663 * cygw32.c: New file. Define Cygwin-specific facilities.
2664 (Fcygwin_convert_path_to_windows)
2665 (Fcygwin_convert_path_from_windows): New user functions for
2666 accessing Cygwin path-munging routines.
2668 * cygw32.h: New file.
2669 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2670 UTF-16LE strings temporarily inside non-Lisp-visible string
2673 (w32_strerror): Just what it says on the tin.
2675 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2676 also run for Cygwin; both systems have the same problem with using
2677 GUI facilities in a forked child. Also call syms_of_cygw32,
2678 syms_of_w32select in correct places.
2680 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2681 needs fork-then-exec for daemon launching.
2683 * font.h: Include frame.h.
2685 * image.c: Use the image library cache machinery only when we're
2686 compiling for native WINDOWSNT; Cygwin can use shared libraries
2687 like any other Unixlike system.
2689 * keyboard.c: Clarify a comment regarding the input loop.
2691 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2692 functions directly instead of trying to detect at runtime that our
2693 host operating system supports them. We make this change for two
2694 reasons: Cygwin lacks support for the multibyte character
2695 conversion functions used by the legacy menu code, and Cygwin
2696 never needs to rely on non-Unicode APIs.
2698 * unexw32.c (hinst): Declare extern.
2700 * w32.c: Change header order;
2701 (w32_strerror): Move to w32fns.c because we need it for
2702 non-WINDOWSNT builds.
2704 * w32.h: Add #error macro to make sure we don't include w32.h for
2705 Cygwin builds. Remove w32select declarations.
2707 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2708 w32fns.c. w32console.c is WINDOWSNT-only.
2710 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2711 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2713 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2714 (w32_major_version, w32_minor_version, w32_build_number)
2715 (os_subtype, sound_type): Define here
2716 (w32_defined_color): Make color parameter const for consistency
2717 with other _defined_color functions.
2718 (w32_createwindow): Unconditionally call w32_init_class instead of
2719 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2720 through the code is complex and unnecessary because class
2721 registration is practically free.
2722 (w32_name_of_message): New EMACSDEBUG-only function.
2723 (Fset_message_beep): Move here
2724 (Fx_open_connection): Require that the display name for Windows be
2725 "w32" for consistency, emacsclient disambiguation, and maybe, one
2726 day, multi-window-system support.
2727 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2728 Cygwin files for W32 GUI facilities, since these clearly don't
2729 expect Cygwin names.
2730 (_DebPrint): Define.
2731 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2732 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2733 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2734 (w32_last_error): Remove.
2736 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2738 * w32heap.c (syspage_mask): Declare here.
2739 (cache_system_info): Remove.
2741 * w32inevt.c (faked_key): Define globally, not statically.
2742 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2743 (w32_console_toggle_lock_key): Move to w32fns.c.
2745 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2747 * w32proc.c (_DebPrint): Move to w32fns.c.
2748 * w32select.c: Include string.h, stdio.h for Cygwin.
2749 * w32select.h: New File.
2751 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2753 (w32_message_fd): New variable. Under Cygwin, holds the file
2754 descriptor the system used to tell us about pending thread
2757 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2758 that prevented compilation under non-WINDOWSNT systems.
2760 (w32_initialize): Open /dev/windows and assign it to
2761 w32_message_fd. Provide w32 feature.
2763 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2764 (WM_EMACS_INPUT_READY): add.
2765 (prepend_msg, w32_message_fd): Declare globally.
2768 (keyboard_handle): Use only when WINDOWSNT.
2769 (notify_msg_ready): New function. Posts a message to the main
2770 thread's message queue under CYGWIN, which wakes up the main
2771 thread from select(2) by making the /dev/windows file descriptor
2772 ready. Under WINDOWSNT, it sets an event the same way the old
2775 (post, prepend_msg): Actually call notify_msg_ready instead of
2776 setting the input event directly.
2778 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2780 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2781 but it still has blocs in it, don't return it to the system,
2782 instead of aborting. (Bug#12402)
2784 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2786 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2788 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2789 MAC_OS_X_VERSION_10_6.
2790 (syms_of_nsterm): Remove comment about Panther and above for
2792 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2793 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2794 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2796 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2797 MAC_OS_X_VERSION_10_4.
2799 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2800 MAC_OS_X_VERSION_10_2.
2802 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2804 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2805 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2807 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2808 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2809 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2810 Remove ns_in_resize check.
2811 (ns_clear_frame_area): Remove resize handle code.
2813 * nsfns.m (ns_in_resize): Remove.
2814 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2815 Remove ns_in_resize check.
2817 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2819 Improve sys_siglist detection.
2820 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2821 defined as a macro, as is done in Solaris.
2822 (sys_siglist_entries): New macro.
2823 (save_strsignal): Use it.
2824 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2825 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2827 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2829 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2830 fullscreen/Fullscreen.
2832 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2833 tobar_height is new.
2835 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2836 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2837 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2838 (windowDidResize:): Check for correct window if old style fullscreen.
2839 Capitalize word in comment. Remove incorrect comment.
2840 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2841 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2842 error in drawing background.
2843 (toggleFullScreen:): Remove comment. Rearrange calls.

2852 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2854 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2856 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2857 that time stamps of directories could also be changed.
2858 Don't request the too broad GENERIC_WRITE, only the more restrictive
2859 FILE_WRITE_ATTRIBUTES access rights.
2861 * fileio.c (Fset_file_times): Special-case ignoring errors for
2862 directories only on MSDOS, not on MS-Windows.
2864 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2866 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2868 2012-10-04 Eli Zaretskii <eliz@gnu.org>

2871 see whether CreateFile failed.
2873 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2875 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2876 to avoid similar races.
2877 * keyboard.c (pending_signals): Now bool, not int.
2879 Port timers to OpenBSD, plus check for timer failures.
2880 OpenBSD problem reported by Han Boetes.
2881 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2883 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2884 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2885 like OpenBSD, which has timer_settime but does not declare it.
2886 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2887 whether to use itimerspec-related primitives. All uses of
2888 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2890 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2892 * profiler.c (handle_profiler_signal): Fix a malloc race
2893 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2895 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2897 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2899 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2901 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2902 consistent with the change in return value of 'safe_strsignal'.
2904 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2906 Prefer plain 'static' to 'static inline' (Bug#12541).
2907 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2908 (bidi_set_sor_type, bidi_push_embedding_level)
2909 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

2914 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2915 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2916 Now 'static', not 'static inline'.
2918 Count overruns when profiling; change units to ns.
2919 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2920 Give extra weight to samples after overruns, to attempt to count
2921 the time more accurately.
2922 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2923 the underlying primitives nominally do ns.
2924 (Fprofiler_cpu_start): Document the change. Mention that
2925 the sampling intervals are only approximate.
2927 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2929 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2931 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2932 case for the special 0 coding-system.
2934 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2935 (Fmake_overlay): Remove redundant tests.
2936 (fix_start_end_in_overlays): Remove redundant recentering.
2938 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2940 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2941 Update dependencies.
2943 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2945 Fix a malloc race condition involving strsignal.
2946 A signal can arrive in the middle of a malloc, and Emacs's signal
2947 handler can invoke strsignal, which can invoke malloc, which is
2948 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2949 Fix it by altering the signal handler so that it does not invoke
2951 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2952 * process.c (status_message): Use const pointer, in case strsignal
2953 is #defined to safe_strsignal.
2954 * sysdep.c (sys_siglist, init_signals): Always define and
2955 initialize a substitute sys_siglist if the system does not define
2956 one, even if HAVE_STRSIGNAL.
2957 (safe_strsignal): Rename from strsignal. Always define,
2958 using sys_siglist. Return a const pointer.
2959 * syssignal.h (safe_strsignal): New decl.
2960 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2962 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2964 * w32proc.c (timer_loop): Fix code that waits for timer
2965 expiration, to avoid high CPU usage.
2967 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2969 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2970 (sweep_weak_table): Remove redundant prototypes.
2972 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2974 * emacs.c: Move the inclusion of TERM_HEADER after including
2975 windows.h on WINDOWSNT. This avoids compilation problems with
2978 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2980 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2981 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2982 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2983 as the previous version used 'void *'.
2985 * ralloc.c (ROUNDUP): Fix last change.
2986 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2989 * w32proc.c <disable_itimers>: New static flag.
2990 (init_timers): Initialize it to zero, after creating the critical
2991 sections used by the timer threads.
2992 (term_timers): Set to 1 before deleting the critical sections.
2993 (getitimer, setitimer): If disable_itimers is non-zero, return an
2994 error indication without doing anything. Reported by Fabrice
2995 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2996 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2998 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3001 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3002 term_ntproc after all the other bookkeeping, to get timers working
3003 as long as possible.
3005 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3007 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3008 Suggested by Juri Linkov in
3009 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3011 Prefer plain 'static' to 'static inline' (Bug#12541).
3012 With static functions, modern compilers inline pretty well by
3013 themselves; advice from programmers often hurts as much as it helps.
3014 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3015 this change shrinks the text size of the Emacs executable by 1.1%
3016 without affecting CPU significantly in my benchmark.
3017 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3099 Revert the FOLLOW-SYMLINKS change for file-attributes.
3100 Doing it right would require several changes to Tramp, and there's
3101 not enough time to get that tested before the freeze today.
3102 * dired.c (directory_files_internal, Ffile_attributes):
3105 * frame.c (x_report_frame_params): Port better to wider ints.
3106 Do not assume that EMACS_UINT is the same width as uprintmax_t,

3226 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
3228 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
3230 * w32.h (init_timers, term_timers): Add prototypes.
3232 2012-09-30 Kenichi Handa <handa@gnu.org>
3234 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
3235 to the buffer relocation which may be caused by ccl_driver.

3269 (EmacsView): Add variables for fullscreen.
3270 (handleFS, setFSValue, toggleFullScreen): New in EmacsView.
3271 (EmacsFSWindow): New interface for fullscreen.
3273 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
3275 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
3277 2012-09-30 Chong Yidong <cyd@gnu.org>
3279 * fns.c (Frandom): Doc fix.
3281 2012-09-30 Martin Rudalics <rudalics@gmx.at>
3283 * window.c (Vwindow_combination_limit): New default value.
3284 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
3286 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
3288 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
3289 Suggested by Eli Zaretskii in
3290 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
3292 2012-09-30 Eli Zaretskii <eliz@gnu.org>
3294 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
3295 HAVE_TIMER_SETTIME is defined.
3297 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
3299 Profiler improvements: more-accurate timers, overflow checks.
3300 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3301 signal.h, setjmp.h. Include systime.h instead.
3302 (saturated_add): New function.
3303 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
3304 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
3305 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
3307 (enum profiler_cpu_running): New enum.
3308 (profiler_cpu_running): Now of that enum type, not bool.
3309 All uses changed to store the new value.
3310 (handle_profiler_signal): Rename from sigprof_handler_1,
3311 for consistency with other handlers. Do not check whether
3312 cpu_log is a hash-table if garbage collecting, since it
3313 doesn't matter in that case.
3314 (deliver_profiler_signal): Rename from sigprof_handler,
3315 for consistency with other handlers.
3316 (setup_cpu_timer): New function, with much of what used to be in
3317 Fprofiler_cpu_start. Check for out-of-range argument.
3318 Prefer timer_settime if available, and prefer
3319 thread cputime clocks, then process cputime clocks, then
3320 monotonic clocks, to the old realtime clock. Use make_timeval
3321 to round more-correctly when falling back to setitimer.
3322 (Fprofiler_cpu_start): Use it.
3323 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3324 Don't assume that passing NULL as the 2nd argument of setitimer
3325 is the same as passing a pointer to all-zero storage.
3326 Ignore SIGPROF afterwards.
3327 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3328 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3329 non-fatal signal handlers. Ignore SIGPROF on startup.
3330 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3331 in profiler.c, since sysdep.c now uses it.
3333 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
3334 Suggested by Eli Zaretskii in
3335 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

3348 (Fbacktrace_frame): Adjust accordingly.
3350 2012-09-28 Glenn Morris <rgm@gnu.org>
3352 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
3353 (Frun_hook_with_args_until_failure): Doc fixes.
3355 2012-09-28 Eli Zaretskii <eliz@gnu.org>
3357 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
3358 Qautomatic_redisplay and change the symbol name. All users changed.
3360 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
3362 * profiler.c (sigprof_handler): Fix race condition.

3368 2012-09-27 Paul Eggert <eggert@cs.ucla.edu>
3370 Check more robustly for timer_settime.
3371 * Makefile.in (LIB_TIMER_TIME): New macro.
3373 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
3374 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
3377 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
3379 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.

3385 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
3387 * character.h (MAYBE_UNIFY_CHAR): Remove.
3388 * charset.c, charset.h (maybe_unify_char): Now static.
3389 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3390 Since this stuff is now private to charset.c, there's no need for
3391 a public macro and no need to inline by hand.
3393 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
3394 Stefan Monnier <monnier@iro.umontreal.ca>
3395 Juanma Barranquero <lekktu@gmail.com>

3420 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
3422 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
3424 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
3426 Prefer POSIX timers if available.
3427 They avoid a race if the timer is too close to the current time.
3428 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
3429 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
3430 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
3432 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3434 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
3435 CHAR_STRING_ADVANCE.
3436 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
3437 STRING_CHAR_ADVANCE.
3439 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
3441 Move Vlibrary_cache to emacs.c and reset before dumping.

3453 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
3455 * w32.h (Vlibrary_cache): Do not declare.
3457 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3459 * w32proc.c (sys_signal): Handle all signals defined by the
3460 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3461 handlers for signals supported by Windows. Don't override
3462 term_ntproc as the handler for SIGABRT.
3463 (sigaction): Rewrite to call sys_signal instead of duplicating its
3465 (sys_kill): Improve commentary.
3467 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3468 consistency with a signature of a signal handler. All callers
3470 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3471 install term_ntproc as a signal handler for SIGABRT, as that
3472 should be done by the dumped Emacs.
3474 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3476 * w32select.c (term_w32select): Protect against repeated
3477 invocation by setting clipboard_owner to NULL after calling
3480 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
3481 and term_ntproc to their modified signatures.
3483 * character.c (char_string, string_char): Remove calls to
3484 MAYBE_UNIFY_CHAR. See the discussion starting at
3485 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
3488 2012-09-25 Chong Yidong <cyd@gnu.org>
3490 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
3492 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
3494 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
3495 when encountering an unknown bytecode.
3497 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3499 image.c, indent.c: Use bool for booleans.
3500 * dispextern.h (struct image_type): Members valid_p, load, init
3501 now return bool, not int. All uses changed.
3502 * image.c: Omit unnecessary static decls.
3503 (x_create_bitmap_mask, x_build_heuristic_mask):

3539 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3541 Move pid_t related decls out of lisp.h.
3542 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3543 (interruptible_wait_for_termination):
3544 Move these decls from lisp.h to syswait.h, since they use pid_t.
3545 Needed on FreeBSD; see Herbert J. Skuhra in
3546 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3547 * callproc.c: Include syswait.h.

3593 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3595 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3596 fatal_error_backtrace.
3598 * w32proc.c (sys_kill): Undo last change: don't do anything when
3599 invoked to deliver SIGABRT to our own process. This is now
3600 handled by emacs_raise.
3602 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3604 * w32term.c (w32_read_socket): Remove leftover reference to
3605 interrupt_input_pending.
3607 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3609 Do not use SA_NODEFER.
3610 Problem reported by Dani Moncayo in
3611 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3613 * sysdep.c (emacs_abort): Do not reset signal handler.
3614 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3615 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3616 wanted even on POSIXish hosts, and it doesn't work on Windows.
3618 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3620 * xterm.c (x_term_init): Call fixup_locale before and after calling
3621 gtk_init (Bug#12392).
3623 2012-09-23 Chong Yidong <cyd@gnu.org>
3625 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3626 Vdynamic_library_alist.
3628 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3629 (Fgnutls_available_p): Caller changed.
3631 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3632 (Flibxml_parse_xml_region): Likewise.
3634 * dispextern.h (struct image_type): Remove arg from init function.
3636 * image.c (Finit_image_library, lookup_image_type)
3637 (define_image_type): Remove now-unneeded second arg.
3638 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3639 (init_tiff_functions, init_gif_functions, init_svg_functions):
3640 Arglist and w32_delayed_load calling convention changed.
3641 (gs_type): Remove init_gs_functions; there is no such function.
3642 (valid_image_p, make_image): Fix caller to lookup_image_type.
3644 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3646 Simplify and avoid signal-handling races (Bug#12471).
3648 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3649 Avoid recursive loop if there's a fatal error in the function itself.
3650 * atimer.c (pending_atimers):
3651 * blockinput.h: Don't include "atimer.h"; no longer needed.
3652 (interrupt_input_pending): Remove. All uses removed.
3653 pending_signals now counts both atimers and ordinary interrupts.
3654 This is less racy than having three separate pending-signal flags.
3655 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3657 Rename from their upper-case counterparts BLOCK_INPUT,
3658 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3659 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3660 This makes it easier to access volatile variables more accurately.
3661 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3662 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3663 that's more reliable if the code is buggy and sets
3664 interrupt_input_blocked to a negative value. All uses changed.
3665 * atimer.c (deliver_alarm_signal):
3666 Remove. No need to deliver this to the parent; any thread can
3667 handle this signal now. All uses replaced by underlying handler.
3668 * atimer.c (turn_on_atimers):
3669 * dispnew.c (handle_window_change_signal):
3670 * emacs.c (handle_danger_signal):
3671 * keyboard.c (kbd_buffer_get_event):
3672 Don't reestablish signal handler; not needed with sigaction.
3673 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3675 Rework to avoid unnecessary accesses to volatile variables.
3676 (UNBLOCK_INPUT_TO): Now a function.
3677 (totally_unblock_input, unblock_input): New decls.
3678 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3679 (init_data): Remove. Necessary stuff now done in init_signal.
3680 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3681 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3682 (fatal_error_code): Remove; no longer needed.
3683 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3684 it doesn't always backtrace. All uses changed. No need to reset
3685 signal to default, since sigaction and/or die does that for us now.
3686 Use emacs_raise (FOO), not kill (getpid (), FOO).
3687 (main): Check more-accurately whether we're dumping.
3688 Move fatal-error setup to sysdep.c
3689 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3690 * gtkutil.c (xg_get_file_name, xg_get_font):
3691 Remove no-longer-needed signal-mask manipulation.
3692 * keyboard.c, process.c (POLL_FOR_INPUT):
3693 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3694 * keyboard.c (read_avail_input): Remove.
3695 All uses replaced by gobble_input.
3696 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3697 (kbd_buffer_store_event_hold, gobble_input):
3698 (record_asynch_buffer_change) [USABLE_SIGIO]:
3699 (store_user_signal_events):
3700 No need to mess with signal mask.
3701 (gobble_input): If blocking input and there are terminals, simply
3702 set pending_signals to 1 and return. All hooks changed to not
3703 worry about whether input is blocked.
3704 (process_pending_signals): Clear pending_signals before processing
3705 them, in case a signal comes in while we're processing.
3706 By convention callers now test pending_signals before calling us.
3707 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3708 New functions, to support changes to blockinput.h.
3709 (handle_input_available_signal): Now extern.
3710 (reinvoke_input_signal): Remove. All uses replaced by
3712 (quit_count): Now volatile, since a signal handler uses it.
3713 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3714 All callers changed. Block SIGINT only if not already blocked.
3715 Clear sigmask reliably, even if Fsignal returns, which it can.
3716 Omit unnecessary accesses to volatile var.
3717 (quit_throw_to_read_char): No need to restore sigmask.
3718 * keyboard.c (gobble_input, handle_user_signal):
3719 * process.c (wait_reading_process_output):
3720 Call signal-handling code rather than killing ourselves.
3721 * lisp.h: Include <float.h>, for...
3722 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3723 (pending_signals): Now volatile.
3724 (syms_of_data): Now const if IEEE floating point.
3725 (handle_input_available_signal) [USABLE_SIGIO]:
3726 (terminate_due_to_signal, record_child_status_change): New decls.
3727 * process.c (create_process): Avoid disaster if memory is exhausted
3728 while we're processing a vfork, by tightening the critical section
3730 (send_process_frame, process_sent_to, handle_pipe_signal)
3731 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3733 (send_process): No need for setjmp/longjmp any more, since the
3734 SIGPIPE stuff is now gone. Instead, report an error if errno
3736 (record_child_status_change): Now extern. PID and W are now args.
3737 Return void, not bool. All callers changed.
3738 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3739 Remove. All uses removed. This bug should be fixed now in a
3741 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3742 and record the child status change directly. This avoids the
3743 need to futz with the signal mask.
3744 (process_fatal_action): Move here from emacs.c.
3745 (emacs_sigaction_flags): New function, containing
3746 much of what used to be in emacs_sigaction_init.
3747 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3748 caught by emacs, to make races less likely.
3749 (deliver_process_signal): Rename from handle_on_main_thread.
3751 (BACKTRACE_LIMIT_MAX): Now at top level.
3752 (thread_backtrace_buffer, threadback_backtrace_pointers):
3754 (deliver_thread_signal, deliver_fatal_thread_signal):
3755 New functions, for more-accurate delivery of thread-specific signals.
3756 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3757 (deliver_arith_signal): Handle in this thread, not
3758 in the main thread, since it's triggered by this thread.
3759 (maybe_fatal_sig): New function.
3760 (init_signals): New arg DUMPING so that we can be more accurate
3761 about whether we're dumping. Caller changed.
3762 Treat thread-specific signals differently from process-general signals.
3763 Block all signals while handling fatal error; that's safer.
3764 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3766 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3767 Ignore SIGPIPE unless batch.
3768 (emacs_backtrace): Output backtrace for the appropriate thread,
3769 which is not necessarily the main thread.
3770 * syssignal.h: Include <stdbool.h>.
3771 (emacs_raise): New macro.
3772 * xterm.c (x_connection_signal): Remove; no longer needed
3773 now that we use sigaction.
3774 (x_connection_closed): No need to mess with sigmask now.
3775 (x_initialize): No need to reset SIGPIPE handler here, since
3776 init_signals does this for us now.
3778 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3780 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3781 background rect may be larger (Bug#12245).
3783 2012-09-23 Chong Yidong <cyd@gnu.org>
3785 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3787 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3789 * .gdbinit: Just stop at fatal_error_backtrace.
3790 See Stefan Monnier's request in
3791 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3792 Remove no-longer-used query of system type.
3794 2012-09-22 Chong Yidong <cyd@gnu.org>
3796 * search.c (Freplace_match): Doc fix (Bug#12325).
3798 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3800 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3801 (Fline_end_position): Doc fix.
3803 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3805 2012-09-22 Chong Yidong <cyd@gnu.org>
3807 * dispextern.h (struct image_type): Add new slot, storing a type
3808 initialization function.
3810 * image.c (define_image_type): Call the image initializer function
3811 if it is defined. Arguments and return value changed.
3812 (valid_image_p, make_image): Callers changed.
3813 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3814 (gif_type, imagemagick_type, svg_type, gs_type):
3815 Add initialization functions.
3816 (Finit_image_library): Call lookup_image_type.
3817 (CHECK_LIB_AVAILABLE): Macro deleted.
3818 (lookup_image_type): Call define_image_type here, rather than via
3819 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3820 (syms_of_image): Move define_image_type calls for xbm_type and
3821 pbm_type to lookup_image_type.
3823 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3825 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3826 'idle_timers' from here ...
3827 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3828 lists, to avoid infloops when the timer does something stupid,
3829 like reinvoke itself with the same or smaller time-out.
3832 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3834 * window.c (Fsplit_window_internal): Handle only Qt value of
3835 Vwindow_combination_limit separately.
3836 (Qtemp_buffer_resize): New symbol.
3837 (Vwindow_combination_limit): New default value.
3840 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3842 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3843 the new overlay string. (Bug#10159)
3845 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3847 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3848 or that fprintf is async-signal-safe. POSIX doesn't require
3851 2012-09-22 Chong Yidong <cyd@gnu.org>
3853 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3856 2012-09-22 Kenichi Handa <handa@gnu.org>
3858 * composite.c (composition_reseat_it): Handle the case that a
3859 grapheme cluster is not covered by a single font (Bug#12352).
3861 2012-09-21 Chong Yidong <cyd@gnu.org>
3863 * image.c (define_image_type): Avoid adding duplicate types to
3864 image_types (Bug#12463). Suggested by Jörg Walter.
3866 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3868 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3869 (print_load_command_name): Add case LC_DATA_IN_CODE.
3870 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3872 2012-09-21 Glenn Morris <rgm@gnu.org>
3874 * eval.c (Frun_hook_with_args_until_success)
3875 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3877 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3879 * fileio.c (Ffile_selinux_context): Only call freecon when
3880 lgetfilecon succeeded.
3881 (Fset_file_selinux_context): Likewise. (Bug#12444)
3883 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3885 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3886 reordering, locate the cursor by calling set_cursor_from_row; if
3887 that fails, clear the desired glyph matrix before returning a
3888 failure indication to the caller. Fixes leaving garbled display
3889 when fast scrolling with a down-key. (Bug#12403)
3890 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3891 scrolling through multibyte text.
3893 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3895 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3896 calling mark_vectorlike since that's the one that marks the window.
3897 (mark_discard_killed_buffers): Mark the final cdr.
3898 * window.h (struct window): Move prev/next_buffers to the
3899 non-standard fields.
3900 * window.c (make_window): Initialize prev/next_buffers manually.
3902 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3904 Omit unused arg EXPECTED from socket hooks.
3905 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3906 * nsterm.m (ns_term_init):
3907 * termhooks.h (struct terminal.read_socket_hook):
3908 * w32inevt.c (w32_console_read_socket):
3909 * w32term.c (w32_read_socket):
3910 * xterm.c (XTread_socket):
3911 Omit unused arg EXPECTED. All callers changed.
3912 (store_user_signal_events): Return void, not int, since callers no
3913 longer care about the return value. All uses changed.
3915 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3917 * w32gui.h (XParseGeometry): Do not declare.
3919 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3921 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3922 Ignore 'expected'. See Eli Zaretskii in
3923 <http://bugs.gnu.org/12471#8> (last line).
3925 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3926 (XParseGeometry): Now static. Substitute extremal values for
3927 values that are out of range.
3929 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3931 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3933 * nsfns.m (XParseGeometry): Remove.
3934 (Fx_create_frame): Call x_set_offset to correctly interpret
3935 top_pos in geometry.
3937 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3938 (Fx_parse_geometry): If there is a space in string, call
3939 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3941 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3943 * search.c (scan_buffer): Use character positions in calls to
3944 region_cache_forward and region_cache_backward, not byte
3945 positions. (Bug#12196)
3947 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3948 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3950 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3951 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3952 emacs_blocked_malloc, now deleted.
3954 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3956 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3957 The workaround was for improving performance on Solaris 2.4, but
3958 is getting in the way now. Emacs will still work if someone is
3959 still running Solaris 2.4 in a museum somewhere; Sun dropped
3960 support for Solaris 2.4 in 2003.
3961 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3962 * process.c (create_process) [HAVE_WORKING_VFORK]:
3963 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3964 since Emacs no longer uses vfork on that platform.
3966 2012-09-17 Glenn Morris <rgm@gnu.org>
3968 * emacs.c: Use COPYRIGHT.
3970 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3972 Remove configure's --without-sync-input option (Bug#12450).
3973 When auditing signal-handling in preparation for cleaning it up,
3974 I found that SYNC_INPUT has race conditions and would be a real
3975 pain to fix. Since it's an undocumented and deprecated
3976 configure-time option, now seems like a good time to remove it.
3977 Also see <http://bugs.gnu.org/11080#16>.
3978 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3979 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3980 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3981 (malloc_hysteresis):
3982 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3983 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3984 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3985 (dont_register_blocks, bytes_used_when_reconsidered)
3986 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3987 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3988 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3989 Remove. All uses removed.
3990 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3991 implementation, one that depends on whether the new macro
3992 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3994 * atimer.c (run_timers, handle_alarm_signal):
3995 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3996 (handle_async_input, process_pending_signals)
3997 (handle_input_available_signal, init_keyboard):
3998 * nsterm.m (ns_read_socket):
3999 * process.c (wait_reading_process_output):
4000 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4001 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4003 * xterm.c (XTread_socket):
4005 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4006 * eval.c (handling_signal): Remove. All uses removed.
4007 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4008 All uses replaced with the SYNC_INPUT version.
4009 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4011 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4014 * font.c (Ffont_shape_gstring): Remove unused local.
4016 2012-09-16 Glenn Morris <rgm@gnu.org>
4018 * Makefile.in (clean): No longer run nextstep's clean.
4020 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4022 (ns-app): Move here from ns.mk, and simplify.
4023 (clean): Simplify nextstep entry.
4024 * ns.mk: Remove file.
4026 2012-09-17 Kenichi Handa <handa@gnu.org>
4028 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4029 not covert the last few charactes.
4031 2012-09-16 Kenichi Handa <handa@gnu.org>
4033 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4034 here, but just check the validity of glyphs in the glyph-string.
4036 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4038 * window.c (Fwindow_parameter, Fset_window_parameter):
4039 Accept any window as argument (Bug#12452).
4041 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4043 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4044 to ns_term_init to avoid memory leak.
4046 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4047 explicit retain/release.
4048 (ns_term_init): Only allow one display. Initialize outerpool and
4051 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4053 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4054 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4055 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4056 the Microsoft problem in a different way, by altering ../nt/config.nt.
4058 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4073 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4074 by lisp.h. This completes removal of setjmp.h inclusion
4075 erroneously announced in the previous commit. (Bug#12446)
4077 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4080 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4081 not defined as a macro. The latter happens on MS-Windows.
4084 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4086 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4087 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4088 Some instances of '#include <setjmp.h>' removed, if the
4089 only reason for the instance was because "lisp.h" was included.
4090 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4091 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4092 and _longjmp with the new symbols. Emacs already uses _setjmp if
4093 available, so this change affects only POSIXish hosts that have
4094 sigsetjmp but not _setjmp, such as some versions of Solaris and
4095 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4096 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4097 (png_load_body) [HAVE_PNG]:
4098 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4099 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4100 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4101 since PNG requires jmp_buf. This is the only exception to the
4102 general rule that we now use sys_setjmp and sys_longjmp.
4103 This exception is OK since this code does not change the signal
4104 mask or longjmp out of a signal handler.
4106 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4108 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4109 Include "syssignal.h", for 'main_thread'.
4111 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4113 Avoid out-of-range marker position (Bug#12426).
4114 * insdel.c (replace_range, replace_range_2):
4115 Adjust markers before overlays, as suggested by comments.
4116 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4117 Remove redundant check before calling offset_intervals.
4119 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4121 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4122 current buffer (Bug#12387).
4124 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4126 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4128 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4130 Use a more backwards-compatible timer format (Bug#12430).
4131 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4132 vector element, not from the 4th, since PSECS is now at the end.
4133 (Fcurrent_idle_time): Doc fix.
4135 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4137 Function to mark objects and remove killed buffers at once.
4138 * alloc.c (discard_killed_buffers): Rename to ...
4139 (mark_discard_killed buffers) ... new name. Add marking
4140 of remaining objects. Fix comment. Adjust users.
4141 (mark_object): Do not touch frame buffer lists here.
4142 * frame.c (delete_frame): Reset frame buffer lists here.
4144 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4146 Better workaround for GNOME bug when --enable-gcc-warnings.
4147 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4148 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4149 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4151 Simplify SIGIO usage (Bug#12408).
4152 The code that dealt with SIGIO was crufty and confusing, e.g., it
4153 played tricks like "#undef SIGIO" but these tricks were not used
4154 consistently. Simplify mostly by not #undeffing standard symbols,
4155 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4156 or not as we please) rather than "defined SIGIO" (standard symbol
4157 that we probably shouldn't #undef).
4158 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4159 Modules that need it can include it.
4160 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4161 * dispextern.h (ignore_sigio): New decl.
4162 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4163 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4164 * emacs.c (shut_down_emacs):
4165 * keyboard.c (kbd_buffer_store_event_hold):
4166 Use ignore_sigio rather than invoking 'signal' directly.
4167 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4169 (FIONREAD, SIGIO): Do not #undef.
4170 (tty_read_avail_input): Use #error rather than a syntax error.
4171 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4172 for I_PIPE, used by SETUP_SLAVE_PTY.
4173 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4174 * sysdep.c (croak): Remove; no longer needed. This bit of
4175 temporary code, with Fred N. Fish's comment that it's temporary,
4176 has been in Emacs since at least 1992!
4177 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4178 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4179 * syssignal.h (croak): Remove decl.
4180 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4181 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4182 now that we're termios-only.
4183 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4184 * term.c (dissociate_if_controlling_tty): Use #error rather than
4187 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4188 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4189 to work around GNOME bug 683906.
4190 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4191 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4192 This works around GCC bug 54561.
4194 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4196 More fixes for 'volatile' and setjmp/longjmp.
4197 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4198 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4199 (png_load_body) [HAVE_PNG]:
4200 (jpeg_load_body) [HAVE_JPEG]:
4201 New function, with most of the old parent function's body.
4202 (png_load) [HAVE_PNG]:
4203 (jpeg_load) [HAVE_JPEG]:
4204 Invoke the new function, to avoid longjmp munging our locals.
4205 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4206 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4207 longjmp is passed 2, as the C standard doesn't guarantee this.
4208 Instead, store the failure code into mgr->failure_code.
4210 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4212 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4213 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4214 (syms_of_keyboard): Remove support for unread-command-char.
4216 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4218 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4219 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4220 violation. (Bug#12426)
4222 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4224 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4226 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4228 * eval.c: Add `inhibit-debugger'.
4229 (Qinhibit_debugger): New symbol.
4230 (call_debugger): Bind it instead of Qdebug_on_error.
4231 (maybe_call_debugger): Test Vinhibit_debugger.
4232 (syms_of_eval): Define inhibit-debugger.
4233 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4234 (syms_of_xdisp): Remove inhibit-debug-on-message.
4236 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4238 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4239 If a nonvolatile local variable is written before a _longjmp to
4240 the frame containing the variable, and is read after the _longjmp,
4241 the value read is indeterminate. Some local variables of type
4242 'struct handler' and 'struct catchtag' are used in this way, so
4243 mark each of their slots as volatile if the slot can be set before
4244 _longjmp and read afterwards.
4245 * lisp.h (struct handler): var and chosen_clause are now volatile.
4246 (struct catchtag): val, next, and pdlcount are now volatile.
4248 * bidi.c (bidi_push_it, bidi_pop_it):
4249 * fns.c (copy_hash_table):
4250 * image.c (define_image_type):
4251 * keyboard.c (kbd_buffer_store_event_hold):
4252 * process.c (Fprocess_send_eof):
4253 * xfaces.c (x_create_gc) [HAVE_NS]:
4254 * xgselect.c (xg_select):
4255 Prefer assignment to memcpy when either will do.
4257 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4258 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4259 time an item is removed. No need to mark this function 'inline';
4260 the compiler knows better than we do.
4262 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4264 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4265 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4266 to change_frame_size (Bug#12388).
4267 (windowDidResize:): Pass YES to updateFrameSize.
4269 * nsterm.h: Add delay parameter to updateFrameSize.
4271 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4273 Discard killed buffers from deleted window and frame objects.
4274 This reduces an amount of references to killed buffers and
4275 helps GC to reclaim them faster.
4276 * alloc.c (discard_killed_buffers): New function.
4277 (mark_object): Use it for deleted windows and frames.
4278 (mark_object): If symbol's value is set up for a killed buffer
4279 or deleted frame, restore its global binding.
4280 * data.c (swap_in_global_binding): Add GC notice.
4281 (swap_in_symval_forwarding): Use convenient set_blv_where.
4282 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4283 * window.h: ... to here.
4285 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4287 Convenient macro to check whether the buffer is live.
4288 * buffer.h (BUFFER_LIVE_P): New macro.
4289 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4290 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4292 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4294 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4295 composition cases (Bug#12364).
4297 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4298 overhang of succeeding glyphs overlapping box cursor.
4300 * w32term.c (x_draw_glyph_string): Likewise.
4302 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4304 Simplify, document, and port floating-point (Bug#12381).
4305 The porting part of this patch fixes bugs on non-IEEE platforms
4306 with frexp, ldexp, logb.
4307 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4309 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4310 support, by removing commented-out code and briefly listing the
4311 C89 functions excluded. The commented-out stuff was confusing
4312 maintenance, e.g., we thought we needed cbrt but it was commented out.
4313 (logb): Remove decl; no longer needed.
4314 (isfinite): New macro, if not already supplied.
4315 (isnan): Don't replace any existing macro.
4316 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4317 are present on all C89 platforms.
4318 (Ffrexp): Do not special-case zero, as frexp does the right thing
4320 (Flogb): Do not use logb, as it doesn't have the desired meaning
4321 on hosts that use non-base-2 floating point. Instead, stick with
4322 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4323 frexp, to avoid getting an unspecified result.
4325 * xdisp.c (Qinhibit_debug_on_message): Now static.
4327 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4329 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4330 NSBezierPath (Bug#12131).
4332 2012-09-10 Chong Yidong <cyd@gnu.org>
4334 * fns.c (Fdelq, Fdelete): Doc fix.
4336 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4338 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4339 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4341 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4343 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4344 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4347 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4349 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4350 left fringe if the window has a left margin. This avoids leaving
4351 traces of the cursor because its leftmost pixel is not drawn over.
4353 * dispnew.c (update_window_line): When the left margin area of a
4354 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4355 that screen line. (Bug#12277)
4357 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4359 Assume C89 or later for math functions (Bug#12381).
4360 This simplifies the code, and makes it a bit smaller and faster,
4361 and (most important) makes it easier to clean up signal handling
4362 since we can stop worring about floating-point exceptions in
4363 library code. That was a problem before C89, but the problem
4364 went away many years ago on all practical Emacs targets.
4365 * data.c, image.c, lread.c, print.c:
4366 Don't include <math.h>; no longer needed.
4367 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4368 might be autoconfigured, as that never happens.
4370 * doprnt.c (DBL_MAX_10_EXP):
4371 * print.c (DBL_DIG):
4372 Remove. C89 or later always defines these.
4373 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4374 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4375 (arith_error, domain_error, domain_error2):
4376 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4377 no longer needed -- we simply return what C returns. All uses removed.
4378 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4380 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4381 Remove. All uses expanded, as these macros are no longer used
4382 more than once and are now more trouble than they're worth.
4383 (Ftan): Use tan, not sin / cos.
4384 (Flogb): Assume C89 frexp.
4385 (fmod_float): Assume C89 fmod.
4386 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4387 (init_floatfns): Remove. All uses removed.
4389 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4391 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4392 compositeToPoint for OSX < 10.6 (Bug#12390).
4394 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4396 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4397 This produces more-accurate results.
4399 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4401 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4402 changes (Bug#12088).
4404 2012-09-08 Chong Yidong <cyd@gnu.org>
4406 * syntax.c (Fstring_to_syntax): Doc fix.
4408 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4410 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4411 in the internal border.
4412 (x_set_window_size): Remove static variables and their usage.
4413 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4414 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4415 Remove fringe/internal border adjustment (Bug#11052).
4416 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4417 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4418 (ns_fix_rect_ibw): Remove.
4419 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4420 (ns_dumpglyphs_box_or_relief): Ditto.
4421 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4423 (ns_dumpglyphs_image): Ditto.
4424 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4426 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4427 their usage. Add fringe_extended_p and its use as in other terms.
4428 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4429 scroll bar was removed.
4430 (updateFrameSize): New function.
4431 (windowDidResize): Move code to updateFrameSize and call it.
4433 * nsterm.h (EmacsView): Add updateFrameSize.
4435 2012-09-07 Chong Yidong <cyd@gnu.org>
4437 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4439 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4441 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4443 More signal-handler cleanup (Bug#12327).
4444 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4445 Problem introduced when merging patches. Noted by Eli Zaretskii in
4446 <http://bugs.gnu.org/12327#67>.
4447 * floatfns.c: Comment fix.
4448 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4449 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4450 and anyway the declaration is harmless even if SIGDANGER is not defined.
4451 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4452 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4453 source files not surprisingly expected syssignal.h to define, or
4454 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4455 Include <sys/ioctl.h>, for FIONREAD.
4456 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4457 This eliminates a problem whereby other files mysteriously had
4458 to include "syssignal.h" before including "systty.h" if they
4459 wanted to use "#ifdef SIGIO".
4461 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4463 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4465 * w32.c (sigemptyset): Empty the set.
4466 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4468 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4470 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4472 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4473 (mark_object): Likewise for frame objects.
4475 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4477 * syssignal.h (handle_on_main_thread): Always declare,
4478 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4479 This ports to platforms without HAVE_PTHREAD.
4481 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4483 Signal-handler cleanup (Bug#12327).
4484 Emacs's signal handlers were written in the old 4.2BSD style with
4485 sigblock and sigmask and so forth, and this led to some
4486 inefficiencies and confusion. Rewrite these to use
4487 pthread_sigmask etc. without copying signal sets around. Also,
4488 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4489 'signal', and instead use functions that do not attempt to take
4490 over the system name space. This patch causes Emacs's text
4491 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4492 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4493 Do not include <signal.h> or "syssignal.h", as these
4494 modules do not use signals.
4495 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4496 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4497 Do not include <signal.h>, as "syssignal.h" does that for us now.
4498 * atimer.c (sigmask_atimers): New function.
4499 (block_atimers, unblock_atimers): New functions,
4500 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4502 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4503 no longer needed here.
4504 * emacs.c (main): Inspect existing signal handler with sigaction,
4505 so that there's no need to block and unblock SIGHUP.
4506 * sysdep.c (struct save_signal): New member 'action', replacing
4507 old member 'handler'.
4508 (save_signal_handlers, restore_signal_handlers):
4509 Use sigaction instead of 'signal' to save and restore.
4510 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4511 New function. All users of 'signal' modified to use set_sighandler
4512 if they're writeonly, and to use sys_signal if they're read+write.
4513 (emacs_sigaction_init, forwarded_signal): New functions.
4514 (sys_signal): Remove. All uses replaced by calls to sigaction
4515 and emacs_sigaction_init, or by direct calls to 'signal'.
4516 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4517 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4518 all uses replaced by pthread_sigmask etc. calls.
4519 * syssignal.h: Include <signal.h>.
4520 (emacs_sigaction_init, forwarded_signal): New decls.
4521 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4522 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4523 (sigmask, sys_sigmask): Remove; no longer needed.
4524 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4525 (sigblock, sigunblock, sigfree):
4526 (sigsetmask) [!defined sigsetmask]:
4527 Remove. All uses replaced by pthread_sigmask.
4528 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4529 no longer need to be replaced, and its typical old uses
4530 are now done via emacs_sigaction_init and sigaction.
4531 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4532 (sys_sigdel): Remove; unused.
4533 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4535 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4537 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4538 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4540 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4542 Explicitly mark buffer_defaults and buffer_local_symbols.
4543 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4544 mark_local_symbols here.
4545 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4546 since special buffers aren't marked here any more.
4547 (allocate_buffer): Chain new buffer with all_buffers here...
4548 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4550 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4551 (syms_of_buffer): Remove staticpro of the above.
4552 (init_buffer_once): Set names for buffer_defaults and
4553 buffer_local_symbols.
4555 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4557 Use bool for booleans in font-related modules.
4558 * font.c (font_intern_prop, font_style_to_value)
4559 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4560 (generate_otf_features, font_check_otf_features, font_check_otf)
4561 (font_match_p, font_list_entities, font_at):
4562 * fontset.c (fontset_id_valid_p, reorder_font_vector
4563 (fontset_find_font, Fset_fontset_font)
4564 (face_suitable_for_char_p) [0]:
4565 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4566 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4567 (m17n_flt_initialized, ftfont_shape_by_flt):
4568 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4569 * nsfont.m (nsfont_draw):
4570 * w32font.c (w32font_draw):
4571 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4572 Use bool for booleans.
4573 * font.h: Adjust to above API changes.
4574 (struct font, struct font_driver, struct font_driver_list):
4575 Use bool for booleans.
4576 (struct font): Remove useless member encoding_type.
4578 * fontset.c, xftfont.c: Omit unnecessary static decls.
4580 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4582 * alloc.c (mark_object): Revert window marking code
4583 since it's unsafe for the Fset_window_configuration.
4585 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4587 Fix race conditions with signal handlers and errno (Bug#12327).
4588 Be more systematic about preserving errno whenever a signal
4589 handler returns, even if it's not in the main thread. Do this by
4590 renaming signal handlers to distinguish between signal delivery
4591 and signal handling. All uses changed.
4592 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4593 * data.c (deliver_arith_signal): Rename from arith_error.
4594 * dispnew.c (deliver_window_change_signal): Rename from
4595 window_change_signal.
4596 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4597 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4598 * keyboard.c (deliver_input_available_signal): Rename from
4599 input_available_signal.
4600 (deliver_user_signal): Rename from handle_user_signal.
4601 (deliver_interrupt_signal): Rename from interrupt_signal.
4602 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4603 (deliver_child_signal): Rename from sigchld_handler.
4604 * atimer.c (handle_alarm_signal):
4605 * data.c (handle_arith_signal):
4606 * dispnew.c (handle_window_change_signal):
4607 * emacs.c (handle_fatal_signal, handle_danger_signal):
4608 * keyboard.c (handle_input_available_signal):
4609 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4610 * process.c (handle_pipe_signal, handle_child_signal):
4611 New functions, with the actual signal-handling code taken from the
4612 original respective signal handlers, sans the sporadic attempts to
4613 preserve errno, since that's now done by handle_on_main_thread.
4614 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4615 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4616 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4618 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4619 Move initialization of main_thread to sysdep.c's init_signals.
4620 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4621 our usage, and simplifies the mainline code.
4622 (record_child_status_change): New static function, as a helper
4623 for handle_child_signal, and with most of the old child handler's
4625 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4626 (handle_child_signal): Use the above.
4627 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4628 Moved here from emacs.c.
4629 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4630 code moved here from emacs.c's main function.
4631 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4632 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4633 This lets callers save and restore errno properly.
4635 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4637 Remove redundant or unused things here and there.
4638 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4639 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4640 * editfns.c (Fcompare_buffer_substrings): Likewise.
4641 * frame.h (struct terminal, struct font_driver_list):
4642 Remove redundant declarations.
4643 * window.h (Qleft, Qright): Likewise.
4645 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4647 Do not mark objects from deleted buffers, windows and frames.
4648 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4649 (mark_object): Likewise for windows and frames.
4651 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4653 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4654 buffer_defaults and buffer_local_symbols as valid objects.
4655 Return special value to denote them.
4657 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4659 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4660 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4661 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4662 (file_name_absolute_p, Fsubstitute_in_file_name):
4663 (check_executable, check_writable, Ffile_accessible_directory_p)
4664 (Fset_file_selinux_context, Fdefault_file_modes)
4665 (Finsert_file_contents, choose_write_coding_system)
4666 (Fwrite_region, build_annotations, a_write, e_write)
4668 * filelock.c (boot_time_initialized, get_boot_time)
4669 (get_boot_time_1, lock_file_1, within_one_second):
4670 * floatfns.c (in_float):
4671 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4672 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4673 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4674 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4675 * window.c (compare_window_configurations):
4676 Use bool for booleans.
4677 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4678 (Fdefault_file_modes): Now mode_t, not int, for modes.
4679 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4680 (internal_delete_file): Now returns void, not a (boolean) int,
4681 since nobody was looking at the return value.
4682 * lisp.h, window.h: Adjust to above API changes.
4684 * xdisp.c (set_message): Simplify and reindent last change.
4686 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4688 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4690 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4692 * eval.c (call_debugger): Make the function non-static so that we
4693 can call it from set_message.
4695 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4696 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4698 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4700 Give more-useful info on a fatal error (Bug#12328).
4701 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4702 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4703 of doing the work ourselves.
4704 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4705 do most of the work.
4706 (fatal_error_backtrace): New function, taken from the guts
4707 of the old fatal_error_signal, but with a new option to output
4709 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4710 info about the signal than just its number.
4711 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4712 * sysdep.c: Include <execinfo.h>
4713 (emacs_backtrace): New function, taken partly from the previous
4714 code of the 'die' function.
4715 (emacs_abort): Call fatal_error_backtrace rather than abort.
4717 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4719 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4720 eager (load-time) macro-expansion.
4721 * lisp.mk (lisp): Add macroexp.
4723 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4725 Simplify redefinition of 'abort' (Bug#12316).
4726 Do not try to redefine the 'abort' function. Instead, redo
4727 the code so that it calls 'emacs_abort' rather than 'abort'.
4728 This removes the need for the NO_ABORT configure-time macro
4729 and makes it easier to change the abort code to do a backtrace.
4730 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4731 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4732 Remove; sysdep.c's emacs_abort now takes its place.
4733 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4734 'abort' changed to use 'emacs_abort'.
4735 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4736 (abort) [!defined abort]: Rename to ...
4737 (emacs_abort): ... new name.
4738 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4739 the place of the old 'abort' in emacs.c.
4740 * w32.c, w32fns.c (abort): Do not #undef.
4741 * w32.c (emacs_abort): Rename from w32_abort.
4743 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4745 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4746 offsets[j].dv, since the y axis of the screen coordinates points
4747 down, while the y axis of the font definition coordinates points
4748 up. This fixes display of Arabic diacritics such as KASRA and
4749 KASRATAN. (Bug#11860)
4751 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4753 Be more systematic about _setjmp vs setjmp.
4754 * alloc.c (test_setjmp, mark_stack):
4755 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4756 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4757 (png_load, my_error_exit, jpeg_load):
4758 * process.c (send_process_trap, send_process):
4759 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4760 The underscored versions are up to 30x faster on some hosts.
4761 Formerly, the code used setjmp+longjmp sometimes and
4762 _setjmp+_longjmp at other times, with no particular reason to
4763 prefer setjmp+longjmp.
4765 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4767 Fix minor problem found by static checking.
4768 * buffer.c (Fdelete_all_overlays): Return nil.
4770 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4772 * buffer.c (Fdelete_all_overlays): New function.
4774 2012-09-03 Chong Yidong <cyd@gnu.org>
4776 * gtkutil.c: Add extern decl for Qxft.
4778 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4780 * emacs.c, eval.c: Use bool for boolean.
4781 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4782 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4783 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

4788 (maybe_call_debugger, Fbacktrace):
4789 * process.c (read_process_output, exec_sentinel):
4790 Use bool for booleans.
4791 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4792 All callers changed.
4793 * eval.c (interactive_p): Omit always-true boolean argument
4794 EXCLUDE_SUBRS_P. All callers changed.
4795 * dispextern.h, lisp.h: Reflect above API changes.
4796 * firstfile.c (dummy): Use the address of 'main', whose signature
4797 won't change, instead of the address of 'initialize', whose
4798 signature just changed from int to bool.
4799 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4800 * msdos.c (fatal_error_in_progress): ... from here.
4801 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4803 (redisplay_internal, unwind_redisplay): Simply clear
4804 REDISPLAYING_P when unwinding, instead of saving its previous,
4805 always-false value and then restoring it.
4807 Clean up some extern decls.
4808 Mostly, this hoists extern decls out of .c files and into .h files.
4809 That way, we're more likely to catch errors if the interfaces change.
4810 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4811 declare xg_mark_data.
4812 * dispextern.h (x_frame_parm_handlers):
4814 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4815 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4816 (Qultra_bold, Qoblique, Qitalic):
4817 Move extern decl here from .c file.
4818 * alloc.c (xg_mark_data) [USE_GTK]:
4820 * eval.c (Qlexical_binding):
4821 * fns.c (time) [!HAVE_UNISTD_H]:

4827 * process.c (QCfamily, QCfilter):
4828 * widget.c (free_frame_faces):
4829 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4830 * xfont.c (x_clear_errors):
4831 * xterm.c (x_frame_parm_handlers):
4832 Remove now-redundant extern decls.
4833 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4834 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4836 * xfaces.c: Remove unnecessary static decls.
4837 * xterm.c (updating_frame): Remove decl of nonexistent object.
4839 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4840 when building globals.h, as the objects that are not built on
4841 this host are not needed to compile C files on this host.
4843 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4845 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

4853 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4854 (Fsubstitute_command_keys):

4856 (save_excursion_save, save_excursion_restore)
4857 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
4858 (format_time_string, general_insert_function)
4859 (make_buffer_string, make_buffer_string_both)
4860 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
4861 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)
4862 (copy_text, insert_1, insert_1_both, insert_from_string)
4863 (insert_from_string_before_markers, insert_from_string_1)

4872 (set_intervals_multibyte_1, set_intervals_multibyte):
4873 * keyboard.c (decode_timer):
4874 Use bool for boolean.
4875 * intervals.h, lisp.h, systime.h: Reflect above API changes.

4880 * keymap.c (push_key_description): Print M-TAB as C-M-i
4883 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4885 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4886 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

4891 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4893 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4895 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4896 more than one grapheme cluster passed to the shaper: compute the
4897 offset adjustment values separately for each cluster. (Bug#11860)
4899 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4900 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4901 about implicit conversions from integer to pointer.
4903 2012-09-01 Daniel Colascione <dancol@dancol.org>
4905 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4906 system used too early.
4908 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
4910 Better seed support for (random).
4911 * emacs.c (main): Call init_random.
4912 * fns.c (Frandom): Set the seed from a string argument, if given.
4913 Remove long-obsolete Gentzel cruft.

4923 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
4924 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
4925 all of which have been moved to common code.
4927 * xfaces.c: Include TERM_HEADER instead of listing all possible
4928 window-system headers.
4930 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

4934 directly accessing frame internals.
4936 * w32font.h: Include font.h. Define syms_of_w32font and
4939 * process.c: Include TERM_HEADER instead of listing all possible
4940 window-system headers.
4942 * nsterm.h: Remove declarations now in frame.h.
4943 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
4945 * menu.c: Include TERM_HEADER instead of listing all possible
4946 window-system headers.
4948 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
4951 * keyboard.c: Include TERM_HEADER instead of listing all possible
4952 window-system headers.
4954 * image.c: Include TERM_HEADER instead of listing all possible
4955 window-system headers. Declare Vlibrary_cache when compiling for
4958 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
4959 window system declarations.
4961 * frame.h: Move common functions here: set_frame_menubar,
4962 x_set_window_size, x_sync, x_get_focus_frame,
4963 x_set_mouse_position, x_set_mouse_pixel_position,
4964 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
4965 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
4966 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,

4984 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
4985 the current window system; include in list of objects to link into
4988 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4990 Remove mark_ttys function and fix tty_display_info initialization.
4991 * lisp.h (mark_ttys): Remove prototype.
4992 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
4993 to mark_ttys because all possible values of 'top_frame' slot are
4994 the frames which are reachable from Vframe_list.
4995 * term.c (mark_ttys): Remove.
4996 (init_tty): Safely initialize 'top_frame' slot with Qnil.
4998 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5000 Change struct frame bitfields from unsigned char to unsigned.
5001 * frame.h (struct frame): Change type of 'display_preempted',
5002 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
5003 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
5004 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
5005 bitfields from unsigned char to unsigned.
5007 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5009 Remove unused member of struct x_output and struct w32_output.
5010 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.

5013 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
5015 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
5016 does not become zero (Bug#12234).
5018 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
5020 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
5021 for GCC 4.7.1 x86-64.
5023 2012-08-30 Glenn Morris <rgm@gnu.org>
5025 * lread.c (init_lread): For out-of-tree builds, only add the
5026 source directory's site-lisp dir to the load-path if it exists,
5027 consistent with in-tree builds. (Bug#12302)
5029 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5031 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
5032 button_values to NULL. Call setStykeMask so dialogs get a close button.
5033 (windowShouldClose:): Set window_closed.
5034 (dealloc): New member, free button_values.
5035 (process_dialog:): Make member function. Remove window argument,
5036 replace window with self. Count buttons and allocate and store values
5038 (addButton:value:row:): value is int with the name tag. Call setTag
5039 with tag. Remove return self, declare return value as void.
5040 (addString:row:): Remove return self, declare return value as void.
5041 (addSplit): Remove return self, declare return value as void.
5042 (clicked:): Remove return self, declare return value as void.
5043 Set dialog_return to button_values[seltag]. Code formatting change.
5044 (initFromContents:isQuestion:): Adjust call to process_dialog.
5045 Code formatting change.
5046 (timeout_handler:): Set timer_fired to YES.
5047 (runDialogAt:): Set timer_fired to NO.
5048 Handle click on close button as quit.
5050 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5051 Add window_closed and button_values. Add void as return value for
5052 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5053 Add process_dialog as new member.
5055 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5057 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
5058 is not one of the heaps we manage. (Bug#12242)
5060 2012-08-28 Glenn Morris <rgm@gnu.org>
5062 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

5073 * buffer.c (Fset_buffer_major_mode): Signal an error
5074 if the buffer is dead.
5075 (Fother_buffer, other_buffer_safely): Remove redundant
5078 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
5080 Always use set_buffer_if_live to restore original buffer at unwind.
5081 * buffer.h (record_unwind_current_buffer): New function.
5082 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:

5084 * undo.c, window.c: Adjust users.
5085 * buffer.c (set_buffer_if_live): Fix comment.
5087 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
5089 Fix usage of set_buffer_internal.
5090 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
5091 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
5092 * coding.c (decode_coding): Omit redundant test.

5120 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
5121 and remove last int (actually boolean) argument, which was always 0.
5122 All callers changed.
5123 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
5124 * dispextern.h (struct composition_it): Use bool for boolean.
5125 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
5126 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
5127 * dired.c (file_name_completion):
5128 Use bool for boolean. (This was missed in an earlier change.)
5130 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5132 * window.c (Fset_window_configuration): Revert first part of
5135 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
5137 * nsterm.h (NSPanel): New class variable dialog_return.
5139 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
5140 Initialize dialog_return.
5141 (windowShouldClose:): Use stop instead of stopModalWithCode.
5142 (clicked:): Ditto, and also set dialog_return (Bug#12258).
5143 (timeout_handler:): Use stop instead of abortModal. Send a dummy
5145 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

5190 Use bool for booleans.
5191 * coding.h, lisp.h: Reflect above API changes.
5192 * coding.c: Remove unnecessary static function decls.
5193 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5194 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5195 not a boolean 'int', since callers never look at the return value.
5196 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5197 * coding.h (decoding_buffer_size, encoding_buffer_size)
5198 (emacs_mule_string_char): Remove unused extern decls.
5199 (struct iso_2022_spec, struct coding_system):

5201 (struct emacs_mule_spec): Remove unused field 'full_support'.
5202 All initializations removed.
5203 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5205 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5207 Fix spare memory change (Bug#12286).
5208 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5209 (valid_lisp_object_p): Likewise.
5211 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5213 * window.c (Fset_window_configuration): Record any window's old
5214 buffer if it's replaced (see Bug#8789). If the new current
5215 buffer doesn't appear in the selected window, go to its old
5218 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5220 Special MEM_TYPE_SPARE to denote reserved memory.
5221 * alloc.c (enum mem_type): New memory type.
5222 (refill_memory_reserve): Use new type for spare memory.
5223 This prevents live_cons_p and live_string_p from incorrect
5224 detection of uninitialized objects from spare memory as live.
5226 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5229 * Makefile.in (.PHONY): versioclean -> versionclean.
5231 Remove unused external symbols.
5232 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5233 * window.c (Qwindow_valid_p, decode_valid_window):
5234 Now static, not extern.
5235 * data.c (Qinterval): Remove; unused.
5236 (syms_of_data): Do not define 'interval'.
5237 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5238 * window.h (decode_valid_window):
5241 * character.c, charset.c, chartab.c: Use bool for booleans.

5252 (map_sub_char_table):
5253 Use bool for boolean.
5254 * character.c (str_to_unibyte): Omit last boolean argument; it was
5255 always 0. All callers changed.
5256 * character.h, charset.h: Adjust to match previous changes.
5257 * character.h (char_printable_p): Remove decl of nonexistent function.
5258 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5259 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5260 are all boolean, so make them single-bit bitfields.
5262 * lisp.h (ASET): Remove attempt to detect side effects.
5263 It was meant to be temporary and it often doesn't work,
5264 because when IDX has side effects the behavior of IDX==IDX
5265 is undefined. See Stefan Monnier in
5266 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5268 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5270 * lisp.h (functionp): New function (extracted from Ffunctionp).
5271 (FUNCTIONP): Use it.
5272 * eval.c (Ffunctionp): Use it.
5274 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5276 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5277 as that's faster and simpler than static storage. Don't bother
5278 with the g_main_context_query overhead if g_main_context_pending
5279 says no events are pending.
5280 (gfds, gfds_size): Remove these static vars.
5281 (xgselect_initialize): Remove; no longer needed.
5282 All uses and decls removed.
5284 * emacs.c (fatal_error_signal_hook): Remove.
5285 All uses removed. This leftover from old code was always 0.
5287 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5288 * casefiddle.c (casify_object, casify_region):
5289 * casetab.c (set_case_table):
5290 * category.c, category.h (word_boundary_p):
5291 * category.h (CHAR_HAS_CATEGORY):
5292 Use bool for booleans, instead of int.
5294 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5296 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5298 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5300 On assertion failure, print backtrace if available.
5301 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5302 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5303 * Makefile.in (LIB_EXECINFO): New macro.
5306 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5307 * bytecode.c (exec_byte_code):
5308 * callint.c (check_mark, Fcall_interactively):
5309 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5310 (getenv_internal, sync_process_alive, call_process_exited):
5311 * lisp.h (USE_SAFE_ALLOCA):
5312 Use bool for booleans, instead of int.
5313 * lisp.h, process.h: Adjust prototypes to match above changes.
5314 * callint.c (Fcall_interactively): Don't assume the mark's
5315 offset fits in 'int'.
5317 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5319 * buffer.c, buffer.h: Use bool for boolean.
5320 * buffer.c (reset_buffer_local_variables)

5326 (mmap_enlarge, mmap_set_vars):
5327 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5328 Use bool for booleans, instead of int.
5329 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5330 since the 1-or-0 return value is always ignored anyway.
5331 (mmap_initialized_p):
5332 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5333 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5335 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5337 * bidi.c: Use bool for boolean.
5338 This is a bit more readable, and makes the text segment of bidi.o
5339 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5340 Presumably it's faster too.
5341 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5343 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5344 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5345 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5346 (bidi_explicit_dir_char, bidi_level_of_next_char)
5347 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5348 Use bool for booleans, instead of int.
5349 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5350 (bidi_unshelve_cache): Adjust decls to match code.
5352 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5354 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5357 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5359 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5360 * atimer.h: Include <stdbool.h>.
5362 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5364 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5365 compile time tests instead of run time tests on systems that do
5367 (FRAME_MAC_P): Remove leftover from deleted code.
5368 * frame.c (syms_of_frame): Remove leftover from deleted code.
5370 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5372 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5374 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5376 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5377 Otherwise, the compiler complains about (A?B:C) where B is void
5378 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5379 (fontset_add): Return void, for FONTSET_ADD.
5381 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5383 * alloc.c: Use bool for booleans.
5384 (gc_in_progress, abort_on_gc)
5385 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5386 (dont_register_blocks) [GC_MALLOC_CHECK]:
5387 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5388 (check_string_bytes, make_specified_string, memory_full)
5389 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5390 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5391 (mark_stack, valid_pointer_p, make_pure_string)
5392 (Fgarbage_collect, survives_gc_p, gc_sweep):
5393 Use bool for booleans, instead of int.
5394 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5395 Remove unused local.
5396 * alloc.c (PURE_POINTER_P):
5397 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5398 * editfns.c (Fformat):
5399 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5401 * fns.c (sweep_weak_table):
5402 * lisp.h (suppress_checking, push_message, survives_gc_p)
5403 (make_pure_string, gc_in_progress, abort_on_gc):
5404 * lread.c (readchar, read1):
5405 * print.c (Fprin1_to_string):
5406 * xdisp.c (push_message):
5407 Use bool for booleans affected directly or indirectly by
5410 Make recently-introduced setters macros.
5411 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5412 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5413 (set_fontset_default, set_fontset_fallback): Rename from their
5414 upper-case counterparts, and make them functions rather than macros.
5415 This is more consistent with the other recently-introduced setters.
5416 These don't need to be inline, since they're local.
5418 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5420 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5421 the loop (Bug#12247).
5423 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5425 * lisp.h (vcopy): Use memcpy rather than our own loop.
5426 This fixes a performance regression introduced by the recent
5427 addition of vcopy. This means 'vcopy' will need to be modified
5428 for a copying collector, but that's OK. Also, tighten the
5429 checking in the assertion.
5431 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5433 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5434 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5435 non-base glyph for the width of the base character, according to
5436 what x_draw_composite_glyph_string_foreground expects.
5437 Generate WADJUST value according to composition_gstring_width's
5438 expectations, to produce correct width of the composed character.
5439 Reverse the sign of the DU offset produced by ScriptPlace.
5441 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5443 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5445 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5447 Avoid direct writes to contents member of struct Lisp_Vector.
5448 * lisp.h (vcopy): New function to copy data into vector.
5449 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5450 * fns.c (Ffillarray): Use ASET.
5451 * keyboard.c (timer_check_2): Use AREF and ASET.
5452 (append_tool_bar_item, Frecent_keys): Use vcopy.
5453 * lread.c (read_vector): Use ASET.
5454 * msdos.c (Frecent_doskeys): Use vcopy.
5455 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5456 (Finternal_merge_in_global_face): Use ASET and vcopy.
5457 * xfont.c (xfont_list_pattern): Likewise.
5459 2012-08-21 Martin Rudalics <rudalics@gmx.at>
5461 * window.c (Fwindow_point): For the selected window always return
5462 the position of its buffer's point.
5463 (Fset_window_point): For the selected window always go in its
5464 buffer to the specified position.
5466 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5468 Setter macros for fontsets.
5469 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)

5525 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5527 Rely on <config.h> + <unistd.h> to declare 'environ',
5528 as gnulib does this if the system doesn't.
5529 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5530 Remove declaration. MS-Windows declares it on stdlib.h which is

5564 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5565 Return void, not Lisp_Object. Otherwise, the compiler

6400 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6401 * w32.c (init_environment): Change the default values of many
6402 environment variables in dflt_envvars[] to NULL, to avoid pushing
6403 them into environment when they were not already defined.
6404 Remove the code that deletes site-lisp subdirectories from the default
6405 value of EMACSLOADPATH, as it is no longer needed.
6406 (check_windows_init_file): Now external, not static.
6407 Use Vload_path as is, without adding anything, as this function is now
6408 called when Vload_path is already set up.
6410 * w32.h (check_windows_init_file): Add prototype.
6412 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
6413 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
6414 compatibility with Posix platforms.
6415 (main): Move the call to check_windows_init_file to here from
6417 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
6418 any, in the DEFALT argument into the root of the Emacs build or
6419 installation tree, as appropriate.
6421 * callproc.c (init_callproc_1): Call decode_env_path instead of
6422 doing its equivalent by hand.
6423 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
6424 the code that sets Vexec_path run on MS-Windows.
6426 * lread.c (init_lread): Add comments to #ifdef's.
6428 * msdos.c (dos_set_window_size, IT_update_begin)
6429 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
6430 instead of direct references.

6436 Now constants, not macros.
6438 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
6440 Remove unnecessary casts involving pointers.
6441 These casts are no longer needed now that we assume C89 or later,
6442 since they involve casting to or from void *.
6443 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
6444 (make_pure_float, make_pure_vector):
6445 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

6454 (x_get_window_property, x_get_window_property_as_lisp_data):
6455 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6456 Remove unnecessary pointer casts.
6457 * alloc.c (record_xmalloc): New function.
6458 * lisp.h (record_xmalloc): New decl.
6459 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6460 more like a function. This is because the pointer cast is not
6461 needed. All uses changed.
6462 * print.c (print_string, print_error_message): Avoid length recalc.
6464 Improve fix for macroexp crash with debugging (Bug#12118).
6465 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6466 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6467 not supposed to be invoked from the garbage collector.
6468 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6469 (gc_aset): New function, which is like ASET but can be
6470 used in the garbage collector.
6471 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

6483 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
6484 (map_w32_filename): Improve commentary. Simplify switch.
6485 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
6486 headers (most versions of MinGW w32api don't).
6487 (get_security_info, create_symbolic_link)
6488 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
6490 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
6491 in the argument file name.

6494 (sys_rename): Diagnose renaming of a symlink when the user doesn't
6495 have the required privileges.
6496 (get_file_security_desc_by_name): Rename from
6497 get_file_security_desc.
6498 (stat_worker): New function, with most of the guts of 'stat', and
6499 with addition of handling of symlinks and support for 'lstat'.
6500 If possible, get file's attributes and security information by
6501 handle, not by name. Produce S_IFLNK bit for symlinks, when
6502 called from 'lstat'.
6503 (stat, lstat): New functions, call 'stat_worker'.
6504 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6505 symlinks when the underlying filesystem supports them.
6507 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6509 Fix macroexp crash on Windows with debugging (Bug#12118).
6510 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6511 checking subscripts; problem introduced with the recent
6512 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6513 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6514 since it's used in non-static inline functions now.
6516 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6517 Don't assume buffer size fits in 'int'. Remove unused local.

6535 * character.c (CHARACTER_INLINE):
6536 * charset.c (CHARSET_INLINE):
6537 * composite.c (COMPOSITE_INLINE):
6538 * dispnew.c (DISPEXTERN_INLINE):
6539 * sysdep.c (SYSTIME_INLINE):
6540 Define to EXTERN_INLINE, so that the corresponding functions
6541 are compiled into code.
6542 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6543 (INLINE_HEADER_END): New macros.
6544 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6564 hard-coding the path separator.
6566 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6568 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6569 This how ASET and AREF are supposed to work, and makes
6570 it easier to think about future improvements. See
6571 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6572 * charset.h (set_charset_attr): New function.

6826 does that unconditionally. Remove file, which is now empty.
6828 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
6831 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

6846 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
6847 Move to after the definition of struct Lisp_Char_Table,
6848 since the former now needs that type defined.

6949 * w32inevt.c: Include w32inevt.h.
6950 (w32_read_console_input): New inline function, calls either
6951 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
6952 w32_console_unicode_input.
6953 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
6954 (w32_kbd_patch_key, key_event): Use the codepage returned by
6955 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
6956 (key_event): use uChar.UnicodeChar only if
6957 w32_console_unicode_input is non-zero.

6987 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
6988 enumeration constants, as PURE and HEAP are too general, and clash
6989 with other headers and sources, such as gmalloc.c and the
6990 MS-Windows system headers. All users changed.
6992 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6994 Revert last save_excursion_save and save_excursion_restore changes.
6995 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7005 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
7007 Improve GDB symbol export (Bug#12036).
7008 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7009 arms of an 'if', not using conditional expressions; otherwise GDB
7010 complains about the types in the unevaluated arm when the argument
7011 is an integer literal.
7012 (xgetint): Simplify expression.
7013 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7014 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7015 Zaretskii in <http://bugs.gnu.org/12036#13>.
7016 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7017 needed now that we have gdb_make_enums_visible.
7018 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7019 (enum enum_USE_LSB_TAG):
7020 New enum types, packaging up enums that need to be exported to GDB.

7039 * xfns.c (syms_of_xfns): Likewise.
7041 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7043 Fast save_excursion_save and save_excursion_restore.
7044 * lisp.h (struct Lisp_Excursion): New data type.
7045 (PVEC_EXCURSION): New pseudovector type.
7046 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7047 to deal with it. Adjust comments.

7058 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7060 Fix export of symbols to GDB (Bug#12036).
7061 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
7062 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7063 emacs.c, as this is a more-suitable home. Had this been done earlier
7064 the fix for 12036 would have avoided some of the problems noted in
7065 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7066 would have been more obvious.
7067 * emacs.c: Do not include <verify.h>; no longer needed.
7068 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7069 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7070 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

7076 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7077 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7078 not be usable in #if. This simplifies things.
7080 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7082 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7084 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

7087 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7088 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7089 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7090 Adjust to changes in lisp.h and emacs.c, by using
7091 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7092 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7093 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7094 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7095 instead of gdb_valbits.
7096 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7097 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7098 instead of gdb_array_mark_flag.
7099 (xboolvector): Get size from $->size, not $->header.size.
7100 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7101 (xreload, hook-run, hookpost-run): Remove.
7102 * emacs.c: Include <verify.h>.
7103 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7104 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7106 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7107 (gdb_USE_LSB_TAG): New enum constants.
7108 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7109 Also define these as enum constants, so they're visible to GDB.
7110 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7111 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7112 as constants, so they're visible to GDB.
7113 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
7114 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
7115 Now enum constants, not macros, so they're visible to GDB.
7116 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7117 more convenient now. All uses changed.
7118 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7119 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7121 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7126 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
7128 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7129 add argument, tune behavior, and adjust all callers.
7131 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7133 Use typedef for EMACS_INT, EMACS_UINT.
7134 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7135 than macros. This simplifies debugging in the usual case, since
7136 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7137 and it allows expressions involving EMACS_INT casts.
7138 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7140 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7148 that FOCUS-FRAME can be omitted.
7150 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7152 Adjust buffer text indirection counters at the end of Fkill_buffer.
7153 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7154 buffer is definitely dead. This should really fix an issue reported
7155 by Christoph Scholtes again. (Bug#12007).
7156 (init_buffer_once): Initialize indirection counters of
7157 buffer_defaults and buffer_local_symbols (for sanity and safety).
7159 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7161 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7162 and continuation glyphs on tooltip frames, leave them at zero.
7163 Avoids continued lines in tooltips. (Bug#11832)
7165 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7167 Simplify copy_overlay.
7168 * buffer.c (copy_overlay): Simplify. Use build_marker.

7174 or invalid. (Bug#12025)
7176 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
7177 it signals an error when a tooltip frame is being created.
7179 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7181 Cleanup miscellaneous objects allocation and initialization.
7182 * alloc.c (allocate_misc): Change to static. Add argument to
7183 specify the subtype. Adjust comment and users.
7184 (build_overlay): New function.
7185 * buffer.c (copy_overlays, Fmake_overlay): Use it.
7186 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
7187 (allocate_misc): Remove prototype.
7188 (build_overlay): Add prototype.
7190 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7192 Swap buffer text indirection counters in Fbuffer_swap_text.
7193 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7194 This avoids crash reported by Christoph Scholtes at
7195 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7197 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7199 * nsmenu.m (Popdown_data): New struct.
7200 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7202 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7203 (initWithContentRect): Make imgView and contentView non-static
7204 and autorelease them. Also autorelease img and matrix (Bug#12005).
7205 (dealloc): Remove (Bug#12005).
7207 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7209 Adjust consing_since_gc when objects are explicitly freed.
7210 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
7211 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
7212 (free_cons, free_misc): Subtract object size from consing_since_gc.
7214 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

7218 (live_buffer, set_marker_internal): New function.
7219 (Fset_marker, set_marker_restricted): Use set_marker_internal.
7220 (set_marker_both, set_marker_restricted_both): Use live_buffer.
7222 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7224 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7225 as it's limited by the amount of memory, not by INT_MAX.

7953 * s/aix4-2.h (unix): Remove; no longer needed.
7955 EMACS_TIME simplification (Bug#11875).
7956 This replaces macros (which typically do not work in GDB)

7958 The functional style also makes code easier to read and maintain.
7959 * systime.h: Include <sys/time.h> on all hosts, not just if
7960 WINDOWSNT, since 'struct timeval' is needed in general.

8000 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8001 Prefer snprintf to strncpy.
8002 * nsterm.m (ns_term_init):
8003 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8004 * nsterm.m (ns_term_init):
8005 Avoid the need for strncpy, by using build_string or
8006 make_unibyte_string directly. Use dtoastr, not snprintf.
8007 * process.c (Fmake_network_process): Diagnose service names that
8008 are too long, rather than silently truncating them or creating
8009 non-null-terminated names.
8010 (Fnetwork_interface_info): Likewise, for interface names.
8011 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8012 Prefer sprintf to strncat.

8026 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8027 where argument type is known to be a Lisp_Cons.

8043 the function is called with compile-time constant argument.
8044 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8045 argument, adjust users accordingly. Use build_pure_c_string where

8079 We include usg5-4-common.h, which defines them both.
8081 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8082 O_RDONLY already includes it).
8084 Stop ns builds setting the EMACSLOADPATH environment variable.
8085 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8086 Now it does not set EMACSLOADPATH, just returns the load-path string.
8087 * nsterm.h: Update accordingly.
8088 * lread.c [HAVE_NS]: Include nsterm.h.
8089 (init_lread) [HAVE_NS]: Use ns_load_path.

8099 (ns_init_paths): Do not set EMACSPATH.
8100 * nsterm.h (ns_exec_path): Add it.
8101 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8104 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.

8128 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8130 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8132 Use make_formatted_string to avoid double length calculation.
8133 * lisp.h (make_formatted_string): New prototype.
8134 * alloc.c (make_formatted_string): New function.
8135 * buffer.c (Fgenerate_new_buffer_name): Use it.

8138 * filelock.c (get_boot_time): Likewise.
8139 * frame.c (make_terminal_frame, set_term_frame_name)
8140 (x_report_frame_params): Likewise.

8153 * nsterm.h (ns_etc_directory): Add it.
8154 * callproc.c [HAVE_NS]: Include nsterm.h.
8155 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
8157 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8159 Move marker debugging code under MARKER_DEBUG.
8160 * marker.c (MARKER_DEBUG): Move marker debugging code under
8161 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8162 for bootstrap with --enable-checking (~3x slowdown reported
8163 by Juanma Barranquero <lekktu@gmail.com>).
8164 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8166 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8168 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8169 See <http://bugs.gnu.org/11825#29>.
8171 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8173 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8174 has no font, use the frame's font. (Bug#11813)
8175 (display_line): Add commentary about displaying truncation glyphs
8177 (produce_special_glyphs): Move here from term.c.
8179 * term.c (produce_special_glyphs): Move to xdisp.c.
8181 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8184 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8186 * xdisp.c (display_line): Avoid warning about implicit declaration
8189 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8191 * lisp.h: Remove empty conditional.
8193 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8195 * lread.c (load_path_check): Now static.
8197 Fix some minor --with-ns problems found by static checking.
8198 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8199 (x_set_font) [!HAVE_X_WINDOWS]:
8200 * image.c (xpm_load_image) [HAVE_NS]:
8201 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8202 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8203 Remove unused local.
8204 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8205 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8206 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8207 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8208 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):

8212 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8214 2012-07-07 Glenn Morris <rgm@gnu.org>
8216 * lread.c (load_path_check): New function, split from init_lread.
8217 (init_lread): Reorganize. Motivation:
8218 If EMACSLOADPATH is set, check/warn about that rather than the
8219 defaults, which we are not going to use. Hence we can remove
8220 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8221 Don't warn if site-lisp directories are missing.
8222 If not installed, start from a blank load-path, since
8223 PATH_LOADSEARCH refers to the eventual installation directories.
8225 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8227 Support truncation and continuation glyphs on GUI frames, when
8228 fringes are disabled. (Bug#11832)
8229 * xdisp.c (init_iterator): Get dimensions of truncation and
8230 continuation glyphs even if on GUI frames.
8231 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8232 or both, are absent.
8233 (start_display, move_it_in_display_line_to): Handle the case of a
8234 GUI frame without a fringe to display continuation or truncation
8236 (insert_left_trunc_glyphs): Support GUI frames: make sure
8237 truncation glyphs overwrite enough glyphs from the current line to
8238 have sufficient space in pixels.
8239 (display_line): Support truncation and continuation glyphs on GUI
8240 frames. If some spare pixels are left on the line after inserting
8241 the truncation glyphs, fill that space with a stretch glyph of a
8242 suitably computed width.
8244 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8245 produce_glyphs, to support GUI sessions.
8247 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8249 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8251 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8253 Do not require float-time's arg to fit in time_t (Bug#11825).
8254 This works better on hosts where time_t is unsigned, and where
8255 float-time is applied to the (negative) difference between two times.
8256 * editfns.c (decode_time_components): Last arg is now double *,
8257 not int *, and means to store all the result as a double, without
8258 worrying about whether the seconds part fits in time_t.
8259 All callers changed.
8260 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8261 All callers changed.
8262 (Ffloat_time): Do not fail merely because the specified time falls
8263 outside of time_t range.
8265 2012-07-07 Glenn Morris <rgm@gnu.org>
8267 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8274 Update dependencies.
8276 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8278 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8280 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

8282 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8283 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8284 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

8287 * xfont.c (compare_font_names): Redo to omit the need for casts.
8289 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8291 * xfns.c (Fx_change_window_property): Doc fix.
8292 * w32fns.c (Fx_change_window_property): Doc fix.
8294 * w32fns.c (Fx_window_property): Accept the same arguments as the
8295 X Windows version. Doc fix.
8296 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8298 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8299 Eli Zaretskii <eliz@gnu.org>
8301 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8302 Windows-specific code from nt/config.nt moved here.
8303 Obsolete settings removed.
8305 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8307 * process.c: Avoid unnecessary calls to gettime.
8308 (wait_reading_process_output): Don't get the time of day
8309 when gobbling data immediately and not waiting, as there's no need
8310 for it in that case. This removes a FIXME.
8312 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8314 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8315 is defined (Bug#11768).
8317 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8319 Fix marker debugging code.
8320 * marker.c (byte_char_debug_check): Do not perform the check
8321 if buffer is not multibyte.
8322 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8323 Call byte_char_debug_check with correct arguments.
8325 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8327 Compile marker debugging code only if ENABLE_CHECKING is defined.
8328 * marker.c (byte_char_debug_check, count_markers):
8329 Use only if ENABLE_CHECKING is defined.
8330 (byte_debug_flag): Remove.
8331 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8332 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8334 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8336 Avoid code repetition in marker-related functions.
8337 * marker.c (attach_marker): New function.
8338 (Fset_marker, set_marker_restricted, set_marker_both)
8339 (set_marker_restricted_both): Use it.
8340 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8341 Consistently rename charno to charpos.
8342 (marker_position): Add eassert.
8343 (marker_byte_position): Convert to eassert.

8358 * editfns.c (buildmark): Remove.
8359 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
8360 (save_restriction_save): Use build_marker.
8361 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8362 * window.c (save_window_save): Likewise.
8364 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8366 Do not use Fdelete_overlay in delete_all_overlays
8367 to avoid redundant calls to unchain_overlay.
8368 * buffer.c (drop_overlay): New function.
8369 (delete_all_overlays, Fdelete_overlay): Use it.
8370 * minibuf.c (get_minibuffer): Fix comment.
8372 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8374 Port to OpenBSD 5.1 amd64.
8375 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8376 This is needed for OpenBSD, and should be harmless on all BSD systems.
8377 Also, include <sys/sysctl.h>, as it should be available on all
8378 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8379 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8380 use p_pid member, not kp_proc.pid.
8382 2012-07-06 Glenn Morris <rgm@gnu.org>
8384 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8386 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8388 More xmalloc and related cleanup.
8389 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8390 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

8397 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8399 Omit needless casts involving void * pointers and allocation.
8400 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8401 as the former is more robust if P's type is changed.
8402 Prefer xzalloc to xmalloc + memset 0.
8403 Simplify malloc-or-realloc to realloc.
8404 Don't worry about xmalloc returning a null pointer.
8405 Prefer xstrdup to xmalloc + strcpy.
8406 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8408 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8409 alloca of a constant.
8411 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8413 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8414 hscroll is larger than the line width. Fixes long and futile
8415 looping inside extend_face_to_end_of_line (on a TTY) producing
8416 glyphs that are not needed and thrown away.
8418 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8420 * marker.c (set_marker_restricted_both): Simplify by using
8423 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

8434 followed by gtk_box_set_homogeneous (Bug#11768).
8435 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8436 (update_theme_scrollbar_width, xg_create_scroll_bar):
8437 Use gtk_scrollbar_new (Bug#11768).
8438 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8439 (is_box_type): New function (Bug#11768).
8440 (xg_tool_item_stale_p): Call is_box_type.
8441 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8442 with default display (Bug#11768).
8444 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8446 * xdisp.c (window_hscroll_limited): New function.
8447 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8448 coordinates when window's hscroll is set to insanely large
8451 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8453 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8520 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8521 This should be fixed in a better way; see Eli Zaretskii in
8522 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8523 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8525 * fileio.c (time_error_value): Rename from special_mtime.
8526 The old name's problems were noted by Eli Zaretskii in
8527 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8529 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8530 This variable's comment says Emacs needs at least one GDB-visible
8531 symbol of type enum pvec_type, to work around GDB problems.
8532 The symbol's value doesn't matter.
8534 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8535 that causes compilation to fail on pre-C99 compilers.
8537 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8539 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

8562 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8563 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8564 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8565 abusing vector->header.next.nbytes.
8566 (live_vector_p): Use PVEC_TYPE.
8567 (mark_object): Adapt code to extract pvectype. Use switch.
8569 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8571 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8572 Tighten new eassert a bit.
8574 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8576 Fix compilation with --enable-gcc-warnings and -O1
8578 * doprnt.c (doprnt): Change type of tem to int, initialize
8579 to avoid compiler warning. Add eassert.
8580 * search.c (simple_search): Initialize match_byte to avoid
8581 compiler warning. Add eassert.
8583 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8585 Avoid weird behavior with large horizontal scrolls.
8586 Without this change, for example, large hscroll values would
8587 mess up Emacs's display on Fedora 15 x86, presumably due to
8588 overflows in int calculations in the display code.
8589 Also, if buffers had long lines, Emacs would freeze.
8590 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8591 (set_window_hscroll): New function, containing the old guts of
8592 Fset_window_hscroll. Return the clipped value.
8593 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8594 This avoids the need to check against PTRDIFF_MAX.
8596 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8598 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8600 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8602 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8604 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8605 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8606 since GCC 4.4.6 issues a bogus warning for them.
8608 Fix bugs in file timestamp newness comparisons.
8609 * fileio.c (Ffile_newer_than_file_p):
8610 * lread.c (Fload): Use full timestamp resolution of files,
8611 not just the 1-second resolution, so that files that are only
8612 slightly newer still count as newer.
8613 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8614 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8616 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8618 * fileio.c: Improve handling of file time marker. (Bug#11852)
8619 (special_mtime): New function.
8620 (Finsert_file_contents, Fverify_visited_file_modtime):
8621 Use it to set special mtime values consistently.
8623 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8625 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8626 marker for non-existing file. (Bug#11852)
8628 2012-07-03 Glenn Morris <rgm@gnu.org>
8630 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8631 and did not make it into globals.h).
8633 2012-07-03 Tom Tromey <tromey@redhat.com>
8635 * window.c (Fset_window_margins, Fset_window_fringes)
8636 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8637 * textprop.c (Fprevious_property_change): No longer static.
8638 * syntax.c (Fsyntax_table_p): No longer static.

8660 * intervals.h: Remove EXFUNs.
8661 * fontset.h: Remove EXFUN.

8667 * window.h: Remove EXFUNs.

8669 * xterm.h: Remove EXFUN.
8671 2012-07-03 Glenn Morris <rgm@gnu.org>
8673 * lisp.h (Frandom): Make it visible to C.

8675 buffer for invisible buffers. (Bug#1229)
8677 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8679 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8680 values which aren't power of 2.
8681 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8682 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8685 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8687 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8689 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8691 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8693 * alloc.c (allocate_vector_block): Remove redundant
8694 calls to mallopt if DOUG_LEA_MALLOC is defined.
8695 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8696 avoid calls to mallopt if zero_vector is returned.
8698 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8700 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8701 is enabled, avoid dereferencing NULL current_sblock if
8704 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8706 Cleanup basic buffer management.
8707 * buffer.h (struct buffer): Change layout to use generic vector
8708 marking code. Fix some comments. Change type of 'clip_changed'
8709 to bitfield. Remove unused #ifndef old.
8710 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8711 (GET_OVERLAYS_AT): Fix indentation.
8712 (for_each_per_buffer_object_at): New macro.
8713 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8714 (Fbuffer_local_variables): Use it.
8715 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8716 * alloc.c (allocate_buffer): Adjust to match new layout of
8717 struct buffer. Fix comment.
8718 (mark_overlay): New function.
8719 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8720 Lisp area of struct buffer.
8721 (mark_object): Use it. Adjust marking of misc objects
8722 and related comments.
8724 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8726 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8727 wrapper that is not needed because the wrapped code is a no-op (zero
8728 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8729 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8731 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8733 * alloc.c (mark_buffer): Simplify. Remove prototype.
8734 (mark_object): Add comment. Reorganize marking of vector-like
8735 objects. Use CHECK_LIVE for all vector-like objects except buffers
8736 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8737 Avoid redundant calls to mark_vectorlike for bool vectors.
8739 2012-06-30 Glenn Morris <rgm@gnu.org>
8741 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8743 * epaths.in (PATH_SITELOADSEARCH): New.
8744 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8745 This is rather than relying on --enable-locallisppath elements
8746 having "site-lisp" in their names. (Bug#10208#25, 11658)
8748 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8750 * w32proc.c (sys_select): Accept and ignore one more argument.
8752 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8754 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8755 (pselect) [!MS_DOS]: Redirect to sys_select.
8757 * sysdep.c: Don't include dos.h and dosfns.h.
8759 * process.c (sys_select):
8760 * msdos.c (sys_select): Accept one more argument and ignore it.
8762 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8763 adapt data types and code to that.
8766 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8767 which clashes with the gnulib function of the same name.
8769 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8771 * font.c (font_style_to_value, font_style_symbolic)
8772 (font_prop_validate_style): Add type checks for values in
8775 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8777 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8780 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8782 * xdisp.c (try_window_id): Undo last change.
8784 * w32.c (getwd): Adjust commentary about startup_dir.
8785 (init_environment): Always call sys_access, even in non-MSVC
8786 builds. Don't chdir to the directory of the Emacs executable.
8787 This undoes code from 1997 which was justified by the need to
8788 "avoid conflicts when removing and renaming directories". But its
8789 downside was that every relative file name was being interpreted
8790 relative to the directory of the Emacs executable, which can never
8791 be TRT. In particular, it broke sys_access when called with
8792 relative file names.
8793 (sys_access): Map GetLastError to errno.
8795 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8797 * window.h (struct window): Change type of 'fringes_outside_margins'
8798 to bitfield. Fix comment. Adjust users accordingly.

8801 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8804 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8806 * gnutls.c (emacs_gnutls_handshake):
8807 Add QUIT to make the loop interruptible.
8809 2012-06-29 Glenn Morris <rgm@gnu.org>
8811 * charset.c (init_charset): Make lack of etc/charsets fatal.
8813 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8815 * editfns.c (region_limit): Fix type mismatch.
8817 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8819 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8820 undefined. Convert from xassert to eassert.
8821 * nsmenu.m: Convert from xassert to eassert.
8822 * nsterm.m: Likewise.
8824 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8826 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8828 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8830 Avoid integer overflow on scroll-left and scroll-right.
8831 * window.c (HSCROLL_MAX): New macro.
8832 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8833 overflow when requested scroll falls outside ptrdiff_t range.
8835 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8837 * window.h (struct window): Change type of 'hscroll',
8838 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8839 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8840 Adjust users accordingly.
8841 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8842 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8843 from EMACS_INT to ptrdiff_t.
8844 (make_window): Omit redundant initialization.
8846 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

8850 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8852 * window.h (struct window): Change type of 'use_time' and
8853 'sequence_number' from Lisp_Object to int.

8863 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8864 adjust comments accordingly.

8915 avoid GCC warning about unused macro.
8917 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8919 * alloc.c (allocate_string): Omit intervals initialization.
8920 * alloc.c (make_uninit_multibyte_string): Initialize intervals
8921 as in make_pure_string and make_pure_c_string.
8923 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8925 * alloc.c (allocate_string): Fix last change.
8927 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

8977 * alloc.c: Remove build_string.
8978 * lisp.h: Define build_string as static inline. This provides
8979 a better opportunity to optimize away calls to strlen when the
8980 function is called with compile-time constant argument.
8981 * image.c (imagemagick_error): Convert to build_string.
8982 * w32proc.c (sys_spawnve): Likewise.
8983 * xterm.c (x_term_init): Likewise.
8985 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8987 Use sprintf return value instead of invoking strlen on result.
8988 In the old days this wasn't portable, since some sprintf
8989 implementations returned char *. But they died out years ago and
8990 Emacs already assumes sprintf returns int.
8991 Similarly for float_to_string.
8992 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8993 * ccl.c (ccl_driver):

8999 * xfns.c (syms_of_xfns):
9000 Use sprintf or float_to_string result to avoid need to call strlen.
9001 * data.c (Fnumber_to_string):
9002 Use make_unibyte_string, since the string must be ASCII.
9003 * lisp.h, print.c (float_to_string): Now returns int length.
9004 * term.c (produce_glyphless_glyph):
9005 Use sprintf result rather than recomputing it.
9007 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9008 * Makefile.in (ALL_CFLAGS):

9040 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

9045 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9046 instead of truncating it to 63 (admittedly a generous limit).
9048 * process.c: Fix spelling and caps in comments.

9176 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9178 Support higher-resolution time stamps (Bug#9000).
9179 The time stamps are only nanosecond-resolution at the C level,
9180 since that's the best that any real-world system supports now.
9181 But they are picosecond-resolution at the Lisp level, as that's
9182 easy, and leaves room for future OS improvements.
9184 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9187 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9188 Don't get current time unless it's needed.
9190 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9191 now provides it if it's absent.
9192 (start_atimer): Port to higher-res time stamps.
9193 Check for time stamp overflow. Don't get current time more
9194 often than is needed.
9196 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9197 Include systime.h, not time.h.
9198 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

9204 (struct image): Timestamp now has higher resolution.
9206 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9207 has at least microseconds now. All uses removed.
9208 (update_frame, update_single_window, update_window, update_frame_1)
9209 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9210 (duration_to_sec_usec): Remove; no longer needed.
9212 * editfns.c (time_overflow): Now extern.

9218 (decode_time_components, lisp_seconds_argument): New functions.
9219 (make_time): Now static.
9220 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9221 Report an error if the time is invalid, rather than having the caller
9224 * fileio.c: Include <stat-time.h>
9225 (Fcopy_file): Copy higher-resolution time stamps.
9226 Prefer to set the time stamp via a file descriptor if that works.

9228 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9229 (Fvisited_file_modtime, Fset_visited_file_modtime):
9230 Support higher-resolution time stamps.
9232 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9234 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9236 * image.c (prepare_image_for_display, clear_image_cache)
9237 (lookup_image): Port to higer-resolution time stamps.
9239 * keyboard.c (start_polling, bind_polling_period):
9240 Check for time stamp overflow.
9241 (read_char, kbd_buffer_get_event, timer_start_idle)
9242 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9243 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9244 Port to higher-resolution time stamps. Do not assume time_t is signed.
9245 (decode_timer): New function. Timers are now vectors of length 9,
9246 not 8, to accommodate the picosecond component.
9247 (timer_check_2): Use it.
9249 * nsterm.m (select_timeout, timeval_subtract): Remove.
9250 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9251 as they're a bit more accurate and handle overflow better.
9252 (ns_select): Change prototype to be compatible with pselect.
9253 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9254 * nsterm.h (ns_select): Adjust prototype.
9256 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9257 us-resolution time stamps.
9258 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9260 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9262 * lisp.h (time_overflow): New decl.
9263 (wait_reading_process_output): First arg is now intmax_t, not int,
9264 to accommodate larger waits.
9266 * process.h (struct Lisp_Process.read_output_delay):
9267 Now counts nanoseconds, not microseconds.
9268 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

9271 (wait_reading_process_output):
9272 Port to ns-resolution time stamps.
9273 (Faccept_process_output, wait_reading_process_output):
9274 Check for time stamp overflow. Do not assume time_t is signed.
9275 (select_wrapper): Remove; we now use pselect.
9276 (Fprocess_attributes): Now generates ns-resolution time stamps.
9278 * sysdep.c: Include utimens.h. Don't include utime.h
9279 or worry about struct utimbuf; gnulib does that for us now.
9280 (gettimeofday): Remove; gnulib provides a substitute.
9281 (make_timeval): New function.
9282 (set_file_times): Now sets ns-resolution time stamps.
9283 New arg FD; all uses changed.
9284 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9285 (system_process_attributes):
9286 Now returns ns-resolution time stamp. All uses changed.
9287 Check for time stamp overflow.
9289 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9290 provides a substitute now.
9292 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9293 since it guarantees struct timespec.
9294 (EMACS_TIME): Now struct timespec, so that we can support
9295 ns-resolution time stamps.
9296 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9297 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9298 (EMACS_USECS): Remove.
9299 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9300 so multiply the arg by 1000 before storing it.
9301 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9303 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9304 Port to ns-resolution time stamps.
9305 (EMACS_TIME_NEG_P): Remove; replaced by....
9306 (EMACS_TIME_SIGN): New macro.
9307 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9308 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9309 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9310 (make_timeval, make_lisp_time, decode_time_components): New decls.
9311 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9312 that it mishandled time_t overflow. You can't compare by subtracting!
9313 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9314 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9316 * term.c: Include <sys/time.h>.
9317 (timeval_to_Time): New function, for proper overflow wraparound.

9322 (Fprimitive_undo): Use them when restoring time stamps.
9324 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9325 (w32_get_internal_run_time):
9326 Port to higher-resolution Emacs time stamps.
9327 (ltime): Now accepts single 64-bit integer, as that's more convenient
9330 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9332 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9333 for compatibility with pselect. Support ns-resolution time stamps.
9335 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9337 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9338 Check for time stamp overflow, and support ns-resolution time stamps.
9340 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9341 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9342 (timeval_subtract): Remove; no longer needed.
9343 (XTflash, XTring_bell, x_wait_for_event):
9344 Port to ns-resolution time stamps. Don't assume time_t is signed.
9346 2012-06-22 Chong Yidong <cyd@gnu.org>

9350 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9352 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9353 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9354 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9355 staticidx goes up to 1597 out of 1600 = 0x640.)
9357 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9359 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9360 Otherwise, the umask might be mistakenly 0 while handling input signals.

9382 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9384 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9385 since tty frames can be explicitly named.
9386 (prepare_menu_bars): Likewise.
9388 * term.c (Ftty_top_frame): New function.
9390 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

9394 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9395 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9396 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

9405 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9406 gets killed during executing of this function (Bug#11665).
9407 Try to always return Qt when the buffer has been actually killed.
9408 (Vkill_buffer_query_functions): In doc-string say that functions
9409 run by this hook should not change the current buffer.
9411 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9413 Fix recently-introduced process.c problems found by static checking.

9431 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
9433 * lisp.h (eassert): Assume C89 or later.
9434 This removes the need for CHECK.
9435 (CHECK): Remove. Its comments about always evaluating its
9436 argument were confusing, as 'eassert' typically does not evaluate
9439 * coding.c (produce_chars): Use ptrdiff_t, not int.
9441 * xterm.c (x_draw_underwave): Check for integer overflow.
9442 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9583 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
9585 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct

9594 * frame.c (delete_frame): Remove outdated comment.
9595 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
9596 USE_LISP_UNION_TYPE.

9620 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
9621 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
9622 * lisp.h (USE_LSB_TAG): Allow the builder to compile with

9624 USE_LSB_TAG now is always defined to be either 0 or 1.
9626 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
9627 code works fine either way, and efficiency is not a concern here,
9628 as the union type is for debugging, not for production.
9629 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9630 Use an inline function on all platforms when using the union type,
9631 since this is simpler and 'static inline' can be used portably
9633 (LISP_INITIALLY_ZERO): New macro.
9634 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
9635 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

9662 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
9663 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
9664 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

9704 dbus_type_is_basic if available.
9705 (xd_extract_signed, xd_extract_unsigned): Rename from
9706 extract_signed and extract_unsigned, respectively. Adapt callers.

9717 * xdisp.c (vmessage): Treat frame message as multibyte.
9718 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))

9738 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
9740 2012-06-08 Eli Zaretskii <eliz@gnu.org>
9742 * alloc.c (allocate_vectorlike): Fix last change.

9746 Block-based vector allocation of small vectors.
9747 * lisp.h (struct vectorlike_header): New field `nbytes',
9748 adjust comment accordingly.

9773 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9775 * doprnt.c (doprnt): Truncate multibyte char correctly.
9776 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9777 would mishandle a string argument "Xc" if X was a multibyte
9778 character of length 2: it would truncate after X's first byte
9779 rather than including all of X.
9781 2012-06-06 Chong Yidong <cyd@gnu.org>
9783 * buffer.c (word_wrap): Doc fix.

9832 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9833 Convert pctcpu and pctmem to Lisp float properly.
9834 Let the compiler fold better, as 100.0/0x8000 is exact.
9836 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9838 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9841 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9843 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9845 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
9847 For a 'struct window', replace some Lisp_Object fields to
9848 bitfields where appropriate, remove unused fields.
9849 * window.h (struct window): Remove unused 'last_mark_x' and
9850 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
9851 change its type from Lisp_Object to bitfield.
9852 Change type of 'force_start', 'optional_new_start',
9853 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9854 fields from Lisp_Object to bitfield. Adjust users accordingly.
9856 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9858 Pacify gcc -Wdouble-precision when using Xaw.
9859 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9860 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9861 Use 'float' consistently, rather than 'float' in most places
9862 and 'double' in a couple of places.
9864 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9866 * xdisp.c (handle_stop): Detect whether we have overlay strings
9867 loaded by testing it->current.overlay_string_index to be
9868 non-negative, instead of checking whether n_overlay_strings is
9869 positive. (Bug#11587)
9871 2012-05-31 Chong Yidong <cyd@gnu.org>
9873 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

9879 * search.c (search_buffer): Remove calls to
9880 r_alloc_inhibit_buffer_relocation, as it is now called by
9881 maybe_unify_char, which was the cause of relocation of buffer text
9884 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9886 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9887 for the duration of call to load_charset, to avoid problems with
9888 callers of maybe_unify_char that access buffer text through C
9891 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9892 decrement the inhibition flag, instead of just setting or
9895 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9897 Remove obsolete '#define static' cruft.
9898 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9899 This #undef was "temporary" in 2000; it is no longer needed
9900 now that '#define static' has gone away.
9901 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9902 (gray_bitmap_bits): Remove; no longer needed.
9903 All uses replaced with definiens.

9915 (safe_bcopy): Remove decl; no longer has that name.
9916 (main): Coalesce #if into single bit of code, for simplicity.

9947 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9948 Bug#9642, but explicitly check that the buffer the overlay would
9949 be moved to is live and rearrange lines to make sure that errors
9950 will not put the overlay in an inconsistent state.
9951 (Fdelete_overlay): Cosmetics.
9953 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9955 * w32term.c (my_bring_window_to_top): New function.
9956 (x_raise_frame): Use handle returned by DeferWindowPos, which

9989 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9990 Only r_alloc_inhibit_buffer_relocation needed to be added;
9991 the others were already declared.
9993 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9994 before checking whether it's out of range. Put the check inside
9996 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9998 2012-05-27 Ken Brown <kbrown@cornell.edu>

10010 they are now on lisp.h.
10012 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10014 * search.c (search_buffer): Use it to inhibit relocation of buffer
10015 text while re_search_2 is doing its job, because re_search_2 is
10016 passed C pointers to buffer text. (Bug#11519)
10018 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10019 Update value to 24.

10025 (pos_visible_p): Revert the comparison against bottom_y to what it
10026 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10029 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10031 Fix coding-related core dumps with gcc -ftrapv.
10032 The code was computing A - B, where A and B are pointers, and B is
10033 random garbage. This can lead to core dumps on platforms that
10034 have special pointer registers, and it also leads to core dumps on
10035 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10036 A - B only when B is initialized properly.
10037 * coding.c (coding_set_source, coding_set_destination): Return void.
10038 (coding_change_source, coding_change_destinations): New functions,

10059 moves, call note_mouse_highlight. If help_echo changed, call
10060 gen_help_event to produce help-echo message in the echo area.
10061 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10064 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10066 * lread.c (read1): Simplify slightly to avoid an overflow warning
10067 with GCC 4.7.0 on x86-64.
10069 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10071 * bidi.c (bidi_mirror_char): Revert last change: an int is
10072 definitely wide enough here.
10074 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

10088 Use int, not EMACS_INT, where int is wide enough.
10089 (inhibit_garbage_collection, Fgarbage_collect):
10090 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10091 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10092 int might not be wide enough.

10108 (Foverlay_recenter, last_overlay_modification_hooks_used)
10109 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10110 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10111 (validate_region): Omit unnecessary test for b <= e,
10112 since that's guaranteed by the previous test.
10113 (adjust_overlays_for_delete): Avoid pos + length overflow.
10114 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10115 (report_overlay_modification):
10116 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10117 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10118 Omit pointer cast, which isn't needed anyway, and doesn't work
10119 after the EMACS_INT -> ptrdiff_t change.
10120 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10121 * buffer.h: Adjust decls to match defn changes elsewhere.

10126 not int, to avoid needless 32-bit limit on 64-bit hosts.
10127 (exec_byte_code): Use tighter memory-full test, one that checks
10128 for alloca overflow. Don't compute the address of the object just
10129 before an array, as that's not portable. Use EMACS_INT, not
10130 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10131 * callint.c (Fcall_interactively):
10132 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10133 * callproc.c (call_process_kill, Fcall_process):

10144 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10145 (casify_object): Avoid integer overflow when overallocating buffer.
10146 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

10149 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10150 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

10153 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10154 For CCL_MapSingle, check that content and value are in int range.

10156 Check that Vcode_version_map_vector is a vector.
10157 (resolve_symbol_ccl_program): Check that vector header is in range.
10158 Always copy the vector, so that we can check its contents reliably
10159 now rather than having to recheck each instruction as it's being
10160 executed. Check that vector words fit in 'int'.
10161 (ccl_get_compiled_code, Fregister_ccl_program)
10162 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10163 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10164 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10165 contents are in range.
10166 (Fccl_execute_on_string): Check that status is in range.
10167 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10168 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10169 Accept and return EMACS_INT, not int, because callers can pass values
10170 out of 'int' range.

10176 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10177 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10178 avoid mishandling large integers.

10187 Remove now-unnecessary CHECK_NATNUMs.
10188 (Fdefine_charset_internal): Check ranges here, more carefully.
10189 Don't rely on undefined behavior with signed left shift overflow.
10190 Don't assume unsigned int fits into fixnum, or that fixnum fits
10191 into unsigned int. Don't require max_code to be a valid fixnum;
10192 that's not true for gb10830 4-byte on a 32-bit host. Allow
10193 invalid_code to be a cons, for the same reason. Require code_offset
10194 to be a character. Avoid int overflow if max_char is close
10196 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10197 this is intended anyway and avoids some undefined behavior.
10198 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10199 INDEX_TO_CODE_POINT, as that's what it expects.
10200 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10201 * charset.h (DECODE_CHAR): Return int, not unsigned;
10202 this is what was intended anyway, and it avoids undefined behavior.
10203 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10204 integer-overflow issues.
10205 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10206 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10207 where the argument is EMACS_INT, and this behavior is not intended.
10208 * chartab.c (Fmake_char_table, Fset_char_table_range)
10209 (uniprop_get_decoder, uniprop_get_encoder):
10210 Don't assume fixnum fits in int.
10211 * cmds.c (move_point): New function, that does the gist of
10212 Fforward_char and Fbackward_char, but does so while checking
10213 for integer overflow more accurately.
10214 (Fforward_char, Fbackward_char): Use it.
10215 (Fforward_line, Fend_of_line, internal_self_insert)
10216 (internal_self_insert):
10217 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10998 2012-05-14 Glenn Morris <rgm@gnu.org>
11000 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").

11008 (report_error, report_error_1, make_hdr, copy_sym)
11009 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11010 Make arguments const char *, not char *, to avoid violations of C
11011 standard and to fix some AIX warnings reported by Gilles Pion.
11013 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11015 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11016 already have overlays loaded.
11017 (handle_single_display_spec): Before returning without displaying
11018 fringe bitmap, synchronize the bidi iterator with the main display
11019 iterator, by calling iterate_out_of_display_property.
11020 (iterate_out_of_display_property): Detect buffer iteration by
11021 testing that it->string is a Lisp string.
11022 (get_next_display_element): When the current object is exhausted,
11023 and there's something on it->stack, call set_iterator_to_next to
11024 proceed with what's on the stack, instead of returning zero.
11025 (set_iterator_to_next): If called at the end of a Lisp string,
11026 proceed to consider_string_end without incrementing string
11027 position. Don't increment display vector index past the end of
11028 the display vector. (Bug#11417)
11029 (pos_visible_p): Don't report a position visible when move_it_to
11030 stopped at the last line of window, which happens to be scanned
11031 backwards by the bidi iteration. (Bug#11464)
11033 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11035 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11036 and right-margin display specs even if the spec is invalid or we
11037 are on a TTY, and thus unable to display on the fringes.
11038 That's because the text with the property will not be displayed anyway,
11039 so we need to signal to the caller that this is a "replacing"
11040 display spec. This fixes display when the spec is invalid or we
11043 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11045 * unexaix.c (make_hdr): Fix typo in prototype.

11076 Update dependencies.
11078 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11080 * xgselect.c (xg_select): Put maxfds+1 into a var.
11081 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11083 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11085 2012-05-10 Dave Abrahams <dave@boostpro.com>

11092 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11093 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11094 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11095 Initialize xd_registered_buses.
11097 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11099 Untag more efficiently if USE_LSB_TAG.
11100 This is based on a proposal by YAMAMOTO Mitsuharu in
11101 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11102 For an admittedly artificial (nth 8000 longlist) benchmark on
11103 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11104 Emacs's overall text size by 1%.
11105 * lisp.h (XUNTAG): New macro.
11106 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11107 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11108 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11109 * eval.c (Fautoload):
11110 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11111 * frame.h (XFRAME): Use XUNTAG.
11113 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11114 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11115 Remove unportable assumptions about print widths of types like
11117 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11118 intptr_t when converting between pointer and integer, to avoid GCC
11119 warnings about wrong width.
11121 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11123 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11124 stack for each reader_thread, instead of defaulting to 8MB
11125 determined by the linker. This avoids failures in creating
11126 subprocesses on Windows 7, see the discussion in this thread:
11127 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11129 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11131 Fix up display of the *Minibuf-0* buffer in the mini window.
11132 * keyboard.c (read_char): Don't clear the echo area if there's no
11134 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11135 contents of *Minibuf-0*) if there's no message displayed in its stead.
11137 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11139 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11142 2012-05-06 Chong Yidong <cyd@gnu.org>
11144 * lisp.mk (lisp): Update.
11146 2012-05-05 Jim Meyering <meyering@redhat.com>
11148 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11150 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11152 * data.c (PUT_ERROR): New macro.
11153 (syms_of_data): Use it. Add new error type `user-error'.
11154 * undo.c (user_error): New function.
11155 (Fprimitive_undo): Use it.
11156 * print.c (print_error_message): Adjust print style for `user-error'.
11157 * keyboard.c (user_error): New function.
11158 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11160 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11162 Do not limit current-time-string to years 1000..9999.
11163 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11164 (Fcurrent_time_string): Support any year that is supported by the
11165 underlying localtime representation. Don't use asctime, as it
11166 has undefined behavior for years outside the range -999..9999.
11168 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11170 Fix race conditions involving setenv, gmtime, localtime, asctime.
11171 Without this fix, interrupts could mess up code that uses these
11172 nonreentrant functions, since setting TZ invalidates existing
11173 tm_zone or tzname values, and since most of these functions return
11174 pointers to static storage.
11175 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11176 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11177 Grow the critical sections to include not just invoking
11178 localtime/gmtime, but also accessing these functions' results
11179 including their tm_zone values if any, and any related TZ setting.
11180 (format_time_string): Last arg is now struct tm *, not struct tm **,
11181 so that the struct tm is saved in the critical section.
11182 All callers changed. Simplify allocation of initial buffer, partly
11183 motivated by the fact that memory allocation needs to be outside
11184 the critical section.
11186 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11188 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11189 with RESET_INTERVAL.
11191 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11192 Remove duplicated buffer name initialization.
11194 2012-05-02 Jim Meyering <jim@meyering.net>
11196 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11198 * xfns.c (x_window): Use xstrdup (Bug#11375).
11200 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11202 * xdisp.c (pos_visible_p): If already at a newline from the
11203 display string before the 'while' loop, don't walk back the glyphs
11204 from it3.glyph_row. Solves assertion violation when the display
11205 string begins with a newline (egg.el). (Bug#11367)
11207 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11209 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11212 2012-05-01 Glenn Morris <rgm@gnu.org>
11214 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11215 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11216 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11217 All were removed before 23.1.
11219 * dispnew.c: Remove HAVE_LIBNCURSES test;
11220 it is always true on relevant platforms.
11222 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11223 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11225 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11227 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11229 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11230 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11233 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11235 Do not avoid creating empty evaporating overlays (Bug#9642).
11236 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11237 That is, do not delete an evaporating overlay if it becomes
11238 empty after its bounds are adjusted to fit within its buffer.
11239 This fix caused other problems, and I'm reverting it until we get
11240 to the bottom of them.
11242 2012-04-27 Chong Yidong <cyd@gnu.org>
11244 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11246 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11248 * xdisp.c (pos_visible_p): If the window start position is beyond
11249 ZV, start the display from buffer beginning. Prevents assertion
11250 violation in init_iterator when the minibuffer window is scrolled
11251 via the scroll bar.
11253 * window.c (window_scroll_pixel_based): Likewise.
11255 2012-04-27 Chong Yidong <cyd@gnu.org>
11257 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11259 2012-04-27 Glenn Morris <rgm@gnu.org>
11261 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11262 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11264 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11266 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11267 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11269 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11271 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11272 display element, check also the underlying string or buffer
11273 character. (Bug#11341)
11275 * w32menu.c: Include w32heap.h.
11276 (add_menu_item): If the call to AppendMenuW (via
11277 unicode_append_menu) fails, disable Unicode menus only if we are
11278 running on Windows 9X/Me.
11280 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11282 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11283 (xgetint): Add missing shift for LSB tags.
11285 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11287 * keyboard.c (read_char): Don't wipe echo area for select window
11288 events: These might get delayed via `mouse-autoselect-window'
11291 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11293 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11294 manipulation of :loaded-from data.
11296 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11298 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11299 now a cons (bug#11311).
11301 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11303 Do not create empty overlays with the evaporate property (Bug#9642).
11304 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11305 if it becomes empty after its bounds are adjusted to fit within
11306 its buffer. Without this fix, in a nonempty buffer (let ((o
11307 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11308 yields an empty overlay that has the evaporate property, which is
11309 not supposed to happen.
11311 Fix minor GTK3 problems found by static checking.
11312 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11313 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11314 (struct _EmacsFixedClass, emacs_fixed_get_type):

11317 (emacs_fixed_class_init): Omit unused local.
11318 (emacs_fixed_child_type): Remove; unused.

11320 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11321 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11322 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11323 (EMACS_FIXED_GET_CLASS): Remove; unused.

11327 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11329 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11331 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11332 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11333 (__malloc_size_t, __malloc_ptrdiff_t):
11334 Remove. All uses removed, replaced by the definiens if needed,
11335 since we can assume C89 or better now.
11336 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
11337 (protect_malloc_state, align, get_contiguous_space)

11343 (special_realloc, _realloc_internal_nolock, _realloc_internal)
11344 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11345 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11346 Define using prototypes, not old style.
11347 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11348 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11349 (align): Don't assume that signed integer overflow wraps around.
11350 Omit unused local var.
11351 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

11353 Omit no-longer-needed casts.
11354 (valloc): Use getpagesize, not __getpagesize.
11355 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11356 (struct hdr): The 'magic' member is now size_t, not unsigned long.

11411 * alloc.c: Handle unusual debugging option combinations.
11412 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
11413 since the two debugging options are incompatible.
11414 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
11416 (mem_init, mem_insert, mem_insert_fixup):
11417 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

11427 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11428 Use Emacs indenting style more consistently. Avoid some casts.

11468 row, return zero immediately.
11469 (try_cursor_movement): If inside continuation line, don't back up
11470 farther than the first row after the header line, if any.
11471 Don't consider the header-line row as "partially visible", even if
11472 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

11510 New extern decls, to avoid calling undeclared functions.
11511 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11512 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined

11515 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11516 Remove one incorrect comment and fix another.

11520 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
11521 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
11522 (r_alloc_sbrk): Now static.
11524 Improve ralloc.c interface checking.
11525 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
11526 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

11529 [REL_ALLOC]: ... to here, to check interface.
11530 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
11531 Remove decls. This fixes an "It stinks!".
11533 * alloc.c (which_symbols): Fix alignment issue / type clash.
11535 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11537 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11538 (struct Lisp_Misc_Any): Likewise.
11539 (struct Lisp_Free): Likewise.
11540 * alloc.c (union aligned_Lisp_Symbol): Define.
11541 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
11542 aligned_Lisp_Symbol instead of struct Lisp_Symbol.
11543 (union aligned_Lisp_Misc): Define.
11544 (MARKER_BLOCK_SIZE, struct marker_block): Use union
11545 aligned_Lisp_Misc instead of union Lisp_Misc.
11546 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
11548 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
11550 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
11551 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
11552 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11553 * s/netbsd.h, s/sol2-6.h:
11554 Remove definition of GC_MARK_STACK, since the default now works.
11555 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11556 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11557 no longer the default.
11558 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11560 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11562 * lread.c (lisp_file_lexically_bound_p):
11563 Fix hang at ";-*-\n" (bug#11238).
11565 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11567 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
11568 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

11577 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
11579 2012-04-13 Reuben Thomas <rrt@sc3d.org>
11581 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11583 2012-04-11 Daniel Colascione <dancol@dancol.org>
11585 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11586 against is gone. It's better to use vfork now so that when Cygwin
11587 gains a new, working vfork, we use it automatically (bug#10398).
11589 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11591 * window.c (save_window_save): Obey window-point-insertion-type.

11604 (force_quit_count): New var.
11605 (handle_interrupt): Use it.
11607 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
11609 * w32.c (w32_delayed_load): Record the full path of the library
11610 being loaded (bug#10424).
11612 2012-04-09 Glenn Morris <rgm@gnu.org>
11614 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11615 not just in the obarray, before snarfing them. (Bug#11036)
11617 * Makefile.in ($(leimdir)/leim-list.el):
11618 Pass EMACS rather than BUILT_EMACS.
11620 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
11622 * process.c (make_process):
11623 * process.h: Add integer `gnutls_handshakes_tried' member to
11626 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
11627 Add convenience `GNUTLS_LOG2i' macro.
11629 * gnutls.c (gnutls_log_function2i): Convenience log function.
11630 (emacs_gnutls_read): Use new log functions,
11631 `gnutls_handshakes_tried' process member, and
11632 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11633 attempts per process (connection).
11635 2012-04-09 Chong Yidong <cyd@gnu.org>
11637 * eval.c (Fuser_variable_p, user_variable_p_eh)
11638 (lisp_indirect_variable): Functions deleted.
11639 (Fdefvar): Caller changed.
11641 * callint.c (Finteractive, Fcall_interactively):
11642 * minibuf.c (Fread_variable): Callers changed.
11644 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11646 * xdisp.c (set_cursor_from_row): If the display string appears in
11647 the buffer at position that is closer to point than the position
11648 after the display string, display the cursor on the first glyph of
11649 the display string. Fixes cursor display when a 'display' text
11650 property immediately follows invisible text. (Bug#11094)
11652 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11654 composite.c: use 'double' consistently
11655 * composite.c (get_composition_id): Use 'double' consistently
11656 instead of converting 'float' to 'double' and vice versa; this is
11657 easier to understand and avoids a GCC warning.
11659 2012-04-09 Glenn Morris <rgm@gnu.org>
11661 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11662 preparation for dumping it with emacs. (Bug#4789)
11663 (leimdir): New variable.
11664 ($(leimdir)/leim-list.el): New rule.
11665 (emacs$(EXEEXT)): Depend on leim-list.el.

11668 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
11669 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
11671 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>

11678 * xml.c (init_libxml2_functions) [WINDOWSNT]:
11679 Remove unused local variable.
11681 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
11683 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11684 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11685 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11686 objects, as mark_maybe_pointer will catch them otherwise.
11687 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11688 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
11690 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
11692 Fix typo that broke non-Windows builds.

11695 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11697 Support building on MS-Windows with libxml2.
11699 * makefile.w32-in (OBJ2): Add xml.$(O).
11700 (GLOBAL_SOURCES): Add xml.c.
11701 ($(BLD)/xml.$(O)): New dependency list.
11703 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11704 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11705 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11706 [!WINDOWSNT]: New macros.
11707 (init_libxml2_functions, libxml2_loaded_p): New functions.
11708 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11709 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11710 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11711 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11713 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11714 Call init_libxml2_functions before calling libxml2 functions.
11715 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11717 * emacs.c: Don't include libxml/parser.h.
11718 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11719 xmlCleanupParser directly.
11721 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11723 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11725 * indent.c (Fvertical_motion): If there is a display string at
11726 point, use it.vpos to compute how many lines to backtrack after
11727 move_it_to point. (Bug#11133)
11729 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11731 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11732 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11733 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11734 macros related to unification of CJK characters. For the details,
11735 see the discussion following the message here:
11736 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11738 2012-04-04 Chong Yidong <cyd@gnu.org>
11740 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11742 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11744 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
11745 instead of alloca. (Bug#11138)
11747 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
11749 * w32menu.c (is_simple_dialog): Properly check lisp types.
11752 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11754 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11755 position we get to after a call to move_it_to fails the
11756 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11757 only if we wind up in a string from display property. (Bug#11063)
11759 * window.c (Fdelete_other_windows_internal): Invalidate the row
11760 and column information about mouse highlight, so that redisplay
11761 restores it after reallocating the glyph matrices. (Bug#7464)
11763 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11764 string comes from a `display' text property, use the buffer
11765 position of that property as if we actually saw that position in
11767 (move_it_by_lines): Remove the assertion that
11768 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11769 violated when there's a before-string at the beginning of a line.
11772 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11774 * xdisp.c (append_space_for_newline): If the default face was
11775 remapped, use the remapped face for the appended newline.
11776 (extend_face_to_end_of_line): Use the remapped default face for
11777 extending the face to the end of the line.
11778 (display_line): Call extend_face_to_end_of_line when the default
11779 face was remapped. (Bug#11068)
11781 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11783 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11785 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
11787 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
11789 2012-03-27 Glenn Morris <rgm@gnu.org>
11791 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11794 2012-03-26 Kenichi Handa <handa@m17n.org>
11796 * dispextern.h (struct glyph): Fix previous change. Change the
11797 bit length of glyphless.ch to 25 (Bug#11082).

11801 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11802 (command_loop_1): Use it; inhibit selection update for
11803 handle-select-window too (Bug#8996).
11805 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
11807 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11809 2012-03-25 Kenichi Handa <handa@m17n.org>
11811 * dispextern.h (struct glyph): Change the bit length of
11812 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11814 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11816 * s/ms-w32.h (tzname): Include time.h before redirecting to
11817 _tzname. Fixes the MSVC build. (Bug#9960)
11819 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
11821 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11824 * xterm.c (XTread_socket): Only modify handling_signal if
11825 !SYNC_INPUT. (Bug#11080)
11827 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11829 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11830 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11831 when fetching a multibyte character consumes more bytes than
11832 CHAR_BYTES returns, due to unification of CJK characters in
11833 string_char. (Bug#11073)
11835 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11837 * process.c (wait_reading_process_output): Handle pty disconnect
11838 by refraining from sending oneself a SIGCHLD (bug#10933).
11840 2012-03-22 Chong Yidong <cyd@gnu.org>
11842 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11844 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11845 Mark string as coming from a prefix property.

11851 * xfaces.c (Vface_remapping_alist): Doc fix.
11853 2012-03-20 Eli Zaretskii <eliz@gnu.org>
11855 * w32proc.c (Fw32_set_console_codepage)
11856 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
11859 2012-03-20 Chong Yidong <cyd@gnu.org>
11861 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
11862 to reflect default non-nil value of redisplay-dont-pause.

11867 it fit in a valid range (Bug#11003).
11869 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11871 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11872 that is not from display property, accept the row as a "cursor
11873 row" if one of the string's character has a non-nil `cursor'
11874 property. Fixes cursor positioning when there are newlines in
11875 overlay strings, e.g. in icomplete.el. (Bug#11035)
11877 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11879 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11881 2012-03-12 Chong Yidong <cyd@gnu.org>
11883 * eval.c (inhibit_lisp_code): Rename from
11884 inhibit_window_configuration_change_hook; move from window.c.
11886 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11887 * window.c (run_window_configuration_change_hook)
11888 (syms_of_window): Callers changed.
11890 2012-03-11 Chong Yidong <cyd@gnu.org>
11892 * keymap.c (Fkey_description): Doc fix (Bug#9700).
11894 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
11896 2012-03-10 Chong Yidong <cyd@gnu.org>
11898 * frame.c (other_visible_frames): Don't assume the selected frame
11899 is visible (Bug#10955).
11901 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11903 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11905 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11907 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11908 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11911 2012-03-03 Glenn Morris <rgm@gnu.org>
11913 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11915 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11917 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11918 position past the first glyph_row that ends at ZV. (Bug#10902)
11919 (redisplay_window, next_element_from_string): Fix typos in
11921 (redisplay_window): Pass to move_it_vertically the margin in
11922 pixels, not in screen lines.
11924 2012-03-02 Glenn Morris <rgm@gnu.org>
11926 * buffer.c (buffer-list-update-hook): Doc fix.
11928 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11930 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11931 push_it before setting up the iterator for the first overlay
11932 string, even if we have an empty string loaded.
11933 (next_overlay_string): If there's an empty string on the iterator
11934 stack, pop the stack. (Bug#10903)
11936 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11938 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11939 Suggested by Stefan Monnier in
11940 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11941 * alloc.c (widen_to_Lisp_Object): New static function.
11942 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11943 and widening them to Lisp_Objects. This would work even if
11944 USE_LSB_TAG is defined and wide integers are used, which might
11945 happen in a future version of Emacs.
11947 2012-02-25 Chong Yidong <cyd@gnu.org>
11949 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11952 * xselect.c (Fx_selection_exists_p): Doc fix.
11953 (x_clipboard_manager_save_all): Print an informative message
11954 before saving to clipboard manager.
11956 2012-02-24 Chong Yidong <cyd@gnu.org>
11958 * keyboard.c (process_special_events): Handle all X selection
11959 requests in kbd_buffer, not just the next one (Bug#8869).
11961 2012-02-23 Chong Yidong <cyd@gnu.org>
11963 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11964 call when setting menu-bar-lines and tool-bar-lines parameters.
11965 (unwind_create_frame_1): New helper function.
11967 * window.c (inhibit_window_configuration_change_hook): New var.

11986 when computing $valmask.
11988 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11989 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11990 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11991 It's useless in that case, and it can cause problems on hosts
11992 that allocate halves of EMACS_INT values separately.
11993 Reported by Dan Horák. Diagnosed by Andreas Schwab in

12615 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12616 verifies glyph row's hash code--we have just reallocated the

12781 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12782 is set, removing the need for VIRT_ADDRESS_VARIES.
12783 (PURE_P): Use a more-efficient implementation that needs just one

12790 consistency with the new puresize.h.
12791 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12792 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

12800 behave as if the cursor position were at the window margin.
12802 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12803 and the cursor position is out of bounds, behave as if the cursor
12804 position were at the window margin. (Bug#10075)
12806 2011-11-18 Chong Yidong <cyd@gnu.org>
12808 * window.c (Fwindow_combination_limit): Make first argument

12830 compute_line_metrics.
12831 (compute_line_metrics): Call row_hash, instead of computing the
12834 * dispnew.c (verify_row_hash): Call row_hash for computing the
12835 hash code of a row, instead of duplicating code from xdisp.c.
12837 * dispextern.h (row_hash): Add prototype.
12839 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
12841 * frame.c (delete_frame): Don't delete the terminal when the last

12890 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12891 with user-defined heap size. Bump the default size of the temacs

12895 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12896 current_matrix and desired_matrix. (Bug#9990)
12897 (verify_row_hash) [XASSERTS]: New function.

12942 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
12944 Avoid some portability problems by eschewing 'extern inline' functions.
12945 The trivial performance wins aren't worth the portability hassles; see

12997 This is also needed for porting to any host where GC_MARK_STACK is
12998 not GC_MAKE_GCPROS_NOOPS.
12999 (which_symbols): Use it.

13014 * xmenu.c (cleanup_widget_value_tree): New function.
13015 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

13022 (window_box_width, window_box_left, window_box_left_offset)
13023 (window_box_right, window_box_right_offset): Declare extern.
13024 Otherwise, these inline functions do not conform to C99 and
13025 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13026 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13027 * intervals.c (adjust_intervals_for_insertion)
13028 (adjust_intervals_for_deletion): Now extern, because otherwise the

13030 (static_offset_intervals): Remove.
13031 (offset_intervals): Rewrite using the old contents of
13032 static_offset_intervals. The old version didn't conform to C99
13033 because an extern inline function contained a reference to an
13034 identifier with static linkage.

13099 Move terminal->reference_count++ just before making the frame
13100 official. Move initialization of image_cache_refcount and
13101 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

13269 (w32font_open_internal, compute_metrics):
13270 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13271 instead of calling the "wide" APIs directly.

13338 (bidi_resolve_weak): Don't enter the expensive loop if the current
13339 position is before next_en_pos. Record the bidi type of the first
13340 non-ET, non-BN character we find, in addition to its position.
13341 (bidi_level_of_next_char): Invalidate next_en_type when
13342 next_en_pos is over-stepped.
13344 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13346 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13347 * editfns.c: Rewrite current-time-zone so that it invokes
13348 the equivalent of (format-time-string "%Z") to get the time zone name.
13349 This fixes a bug when the time zone name contains characters that
13350 need converting from the system time locale to Emacs internal format.
13351 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13352 that patch fixed format-time-string to do the conversion, but
13353 I forgot to fix current-time-zone.
13354 (format_time_string): New function, containing most of
13355 what Fformat_time_string used to contain.
13356 (Fformat_time_string): Rewrite in terms of format_time_string.
13357 This doesn't change this function's behavior.
13358 (current-time-zone): Rewrite to use format_time_string.
13359 This fixes the bug reported by Michael Schierl in
13360 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13361 Jason Rumney's 2007-06-07 change worked around this bug, but
13363 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13365 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13367 * xdisp.c (start_display): If the character at POS is displayed
13368 via a display vector, reset IT->current.dpvec_index to zero.
13369 (try_window_reusing_current_matrix): If a line ends in a display
13370 vector or the next line starts in a display vector, continue
13371 redrawing the window even though the character position of
13372 start_row was reached.
13375 2011-10-18 Chong Yidong <cyd@gnu.org>
13377 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13378 with nobreak-char-display too.
13380 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13382 Fix part 3 of bug#9771.
13383 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13384 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13385 non-neutral characters if the current character is a paragraph
13386 separator (a.k.a. Newline). This avoids running the same
13387 expensive loop twice, once when we consume the preceding newline
13388 and the other time when the line actually needs to be displayed.
13389 Avoid the loop when we see neutrals on the base embedding level
13390 following a character whose directionality is the same as the
13391 paragraph's. This avoids running the expensive loop when a line
13392 ends in a long sequence of neutrals, like control characters.
13393 Add assertion against STRONG_AL type. Slightly rearrange code
13394 that determines the type of a neutral given the first non-neutral
13396 (bidi_level_of_next_char): Set next_en_pos to zero when
13397 invalidating its info.
13399 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13401 * xdisp.c (push_display_prop): Determine whether to record string
13402 or buffer position by IT->string, not by IT->method. Allow
13403 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13404 (move_it_vertically_backward): Don't look for character position
13405 immediately after the newline when in a continuation line.
13408 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13410 * window.c (coordinates_in_window): Rewrite and delabelize
13411 vertical border check. (Bug#5357) (Bug#9618)
13413 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13415 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13416 errors in XSetWindowBorder (bug#9310).
13418 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13420 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13421 avoid crash when xmalloc overrun checking is enabled.
13423 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13425 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13426 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13427 cursor motion with <left> and <right> arrow keys.
13429 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13430 some callers set that themselves.
13432 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13434 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13435 display string and the previous row comes from the same string and
13436 is empty. (Bug#9739) (Bug#9738)
13438 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13440 * doc.c (get_doc_string): Encode file name (bug#9735).
13442 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13444 * bidi.c (bidi_level_of_next_char):
13445 * xdisp.c (get_visually_first_element): Remove old incorrect
13446 comments regarding the Unicode Line Separator character.
13448 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13450 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13452 * alloc.c (Fgc_status): Do not access beyond zombies array
13453 boundary if nzombies > MAX_ZOMBIES.
13454 * alloc.c (dump_zombies): Add missing format specifier.
13456 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13458 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13459 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13461 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13462 Some packages use them to denote characters with modifiers.
13464 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13466 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13467 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13468 matching a pp-number. Rename parameter var to var1.
13470 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13472 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13474 2011-10-08 Glenn Morris <rgm@gnu.org>
13476 * callint.c (Fcall_interactively): Give a more explicit error for the
13477 'c' case with a non-character input. (Bug#8479)
13479 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13481 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13483 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13484 lines that are hscrolled on the left.
13486 * dispnew.c (buffer_posn_from_coords): Account for a possible
13487 presence of header-line. (Bug#4426)
13489 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13491 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13492 Don't advertise functionality which we discourage or doesn't work.
13494 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13496 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13497 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13498 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13499 this makes Emacs dump core during garbage collection on rare
13500 occasions. sizeof is obviously inferior to offsetof here, so
13501 stick with offsetof.
13502 (GC_POINTER_ALIGNMENT): New macro.
13503 (mark_memory): Omit 3rd (offset) arg; caller changed.
13504 Don't assume EMACS_INT alignment is the same as pointer alignment.
13506 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13508 * keyboard.c (read_key_sequence_remapped): New var.
13509 (read_key_sequence): Compute remapping in the right buffer.
13510 (command_loop_1): Use read_key_sequence's remapping directly.
13512 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13514 * dired.c (file_name_completion): Don't expand file name.
13515 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13516 before checking file name handler.
13518 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13519 they've been requested explicitly (bug#9591).
13521 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13523 * keymap.c (Fsingle_key_description): Use make_specified_string
13524 instead of build_string to build string from push_key_description.
13527 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13529 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13530 This fixes a Y2038 bug on 64-bit hosts.
13531 * buffer.c (reset_buffer):
13532 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13533 (Fclear_buffer_auto_save_failure):
13534 Use 0, not -1, to represent an unset failure time, since time_t
13535 might not be signed.
13537 Remove dependency on glibc malloc internals.
13538 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13539 Move back here from lisp.h, but with their new implementations.
13540 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13541 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13542 * charset.c (charset_table_init): New static var.
13543 (syms_of_charset): Use it instead of xmalloc. This removes a
13544 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13545 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13546 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13547 Move back to alloc.c.
13548 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13549 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13551 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13553 * nsterm.m (windowDidResize): Call x_set_window_size only when
13554 ns_in_resize is true. Otherwise set pixelwidth/height and
13555 call change_frame_size (Bug#9628).
13557 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13559 Port --enable-checking=all to Fedora 14 x86-64.
13560 * charset.c (syms_of_charset): Also account for glibc malloc's
13561 internal overhead when calculating the initial malloc maximum.
13563 Port --enable-checking=all to Fedora 14 x86.
13564 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13566 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13567 (overrun_check_realloc, overrun_check_free):
13568 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13569 That way, xmalloc returns a properly-aligned pointer even if
13570 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13571 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13572 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13573 into account when calculating the initial malloc maximum.
13574 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13575 Move here from alloc.c, so that charset.c can use it too.
13576 Properly align; the old code wasn't right for common 32-bit hosts
13577 when configured with --enable-checking=all.
13578 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13579 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13581 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13583 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13586 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13588 * xdisp.c (compute_display_string_end): If there's no display
13589 string at CHARPOS, return -1.
13591 * bidi.c (bidi_fetch_char): When compute_display_string_end
13592 returns a negative value, treat the character as a normal
13593 character not covered by a display string. (Bug#9624)
13595 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13597 * lread.c (Fread_from_string): Fix typo in docstring.
13599 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13601 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13602 newline, reseat the iterator instead of bidi-iterating there one
13603 character at a time. (Bug#9610)
13604 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13605 TO_CHARPOS if the bidi iterator is at base embedding level.
13607 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13609 * lread.c (readevalloop): Use correct code for NBSP.
13610 (read1): Likewise. (Bug#9608)
13612 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13614 * dbusbind.c (Fdbus_register_signal): When service is not
13615 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13617 2011-09-25 Glenn Morris <rgm@gnu.org>
13619 * buffer.c (truncate-lines): Doc fix.
13621 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13623 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13624 (Fset_window_next_buffers): Doc fix.
13626 2011-09-24 Glenn Morris <rgm@gnu.org>
13628 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13630 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13632 Fix minor problems found by static checking.
13633 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13634 * indent.c (Fvertical_motion): Fix == vs = typo.
13636 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13638 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13639 Default value is now t. Doc fix.
13641 * indent.c (Fvertical_motion): Compute and apply the overshoot
13642 logic when moving up, not only when moving down. Fix the
13643 confusing name and values of the it_overshoot_expected variable;
13644 logic changes accordingly. (Bug#9254) (Bug#9549)
13646 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13647 CHARPOS is covered by a display string which includes newlines.
13648 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13649 is covered by a display string with embedded newlines.
13651 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13653 * dbusbind.c (Fdbus_register_signal): Add match rule to
13654 Vdbus_registered_objects_table. (Bug#9581)
13655 (Fdbus_register_method, Vdbus_registered_objects_table):
13658 2011-09-24 Jim Meyering <meyering@redhat.com>
13660 do not ignore write error for any output size
13661 The previous change was incomplete.
13662 While it makes emacs --batch detect the vast majority of stdout
13663 write failures, errors were still ignored whenever the output size is
13664 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13665 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13666 && echo FAIL: ignored write error
13667 FAIL: ignored write error
13668 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13669 && echo FAIL: ignored write error
13670 FAIL: ignored write error
13671 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13673 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13675 * emacs.c (Fkill_emacs): In noninteractive mode exit
13676 non-successfully if a write error occurred on stdout. (Bug#9574)
13678 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13680 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13683 * dispextern.h (struct it): Update the comment documenting what
13686 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13688 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13689 a display string, extend search for cursor position to end of row.
13690 (find_row_edges): If the row ends in a newline from a display
13691 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13692 Handle the case of a display string with multiple newlines.
13693 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13694 non-empty line. Fixes confusing cursor motion with arrow keys at
13695 the beginning of a line that starts with whitespace.
13697 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13699 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13702 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13704 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13705 boolean (Bug#9154).
13707 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13709 * xdisp.c (display_line): Record maximum and minimum buffer
13710 positions even if no glyphs were produced (e.g., by a zero-width
13711 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13712 buffer positions that will be removed from the glyph row because
13714 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13715 column is beyond frame width: don't subtract 1 "pixel" when
13716 computing width of the stretch.
13717 (reseat_at_next_visible_line_start): Undo the change made on
13718 2011-09-17 that saved paragraph information and restored it after
13719 the call to `reseat'. (Bug#9545)
13721 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13723 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13724 and turn window cursor on if cleared (Bug#9415).
13726 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13728 * search.c (boyer_moore): Take unibyte characters from pattern
13729 literally. (Bug#9458)
13731 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13733 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13735 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13737 Fix minor problem found by static checking.
13738 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13739 initialized, to pacify gcc -Wuninitialized.
13741 * fileio.c: Report proper errno when syscall falls.
13742 (Finsert_file_contents): Save and restore errno,
13743 so that report_file_error outputs the correct diagnostic.
13744 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13746 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13748 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13750 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13752 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13753 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13755 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13757 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13758 about the current paragraph and restore it after the call to reseat.
13760 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13761 (bidi_find_paragraph_start): Search back for paragraph beginning
13762 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13763 (bidi_move_to_visually_next): Only trigger paragraph-related
13764 computations when the last character is a newline or at EOB, not
13765 just any NEUTRAL_B. (Bug#9470)
13767 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13768 truncated lines if point is covered by a display string. (Bug#9524)
13770 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13772 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13773 (cons_to_x_long): New function.
13774 (lisp_data_to_selection_data): Use it. Correct the test for
13775 short-versus-long data; it was negated. Break out of vector
13776 loop, for efficiency, when a long datum is discovered.
13778 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13780 * eval.c (Fquote): Document its non-consing behavior (bug#9482).

13801 * composite.c (composition_update_it, get_composition_id):
13802 * xdisp.c (get_next_display_element)
13803 (fill_composite_glyph_string): Add comments about special meaning
13804 of TAB characters in a composition.
13806 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13808 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13809 This occurs when processing a multibyte format.
13810 Problem reported by Wolfgang Jenker.
13812 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13814 * xdisp.c (try_cursor_movement): Only check for exact match if
13815 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13817 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13819 Remove unused external symbols.
13820 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13821 * xdisp.c (calc_pixel_width_or_height): Now static.
13822 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

13827 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13829 * xselect.c: Use signed conversions more consistently (Bug#9498).
13830 (selection_data_to_lisp_data): Assume incoming selection data are
13831 signed integers, not unsigned. This is to be consistent with
13832 outgoing selection data, which was modified to use signed integers
13833 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13834 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13835 expects long, not unsigned long.

13845 * frame.c (Fother_visible_frames_p): Function deleted.
13847 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13849 * indent.c (compute_motion): Process display vector front to back
13850 rather than the other way around. (Bug#2496)
13852 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13854 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13856 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13858 * minibuf.c (Fread_from_minibuffer): Doc fix.
13860 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13862 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13863 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13865 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13867 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13868 value for non-existent files.
13870 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13872 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13873 set its "size" to -1. This will set the modtime_size field of
13874 the corresponding buffer to -1, which is what
13875 verify-visited-file-modtime expects for files that do not exist.
13878 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13880 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13882 * lisp.h: ... from here. push_key_description is no longer
13883 defined in keyboard.c, so its declaration should not be in
13884 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13885 logically belongs with push_key_description.
13887 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13889 * buffer.h: Include <sys/types.h> instead of <time.h>.
13890 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13891 Problem reported by Herbert J. Skuhra.
13893 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13895 * xml.c (parse_region): Make the parsing work for
13896 non-comment-starting XML files again (bug#9144).
13898 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13900 * image.c (gif_load): Fix calculation of bottom and right corner.
13903 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13905 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13906 redisplay in small windows.
13908 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13910 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13912 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13914 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13915 Operate on live windows only.
13917 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13919 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13921 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13923 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13924 only under bidi iteration.
13926 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13928 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13930 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13932 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13933 Without this fix, the command to link temacs failed due to an
13934 undefined symbol __builtin_isnan. This is because
13935 /usr/include/iso/math_c99.h #defines isnan(x) to
13936 __builtin_isnan(x), but the bundled gcc, which identifies itself
13937 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13939 * floatfns.c (isnan): #undef, and then #define to a clone of
13941 (Fisnan): Always define, since it's always available now.
13942 (syms_of_floatfns): Always define isnan at the Lisp level.
13944 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13946 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13948 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13950 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13951 The previous code assumed that file offsets (off_t values) fit in
13952 EMACS_INT variables, which is not true on typical 32-bit hosts.
13953 The code messed up by falsely reporting buffer overflow in cases
13954 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13955 when "big" contains more than 2**29 bytes, even though this
13956 inserts just one byte and does not overflow the buffer.
13957 (Finsert_file_contents): Store file offsets as off_t
13958 values, not as EMACS_INT values. Check for overflow when
13959 converting between EMACS_INT and off_t. When checking for
13960 buffer overflow or for overlap, take the offsets into account.
13961 Don't use EMACS_INT for small values where int suffices.
13962 When checking for overlap, fix a typo: ZV was used where
13963 ZV_BYTE was intended.
13964 (Fwrite_region): Don't assume off_t fits into 'long'.
13965 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13967 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13969 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13971 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13973 sprintf-related integer and memory overflow issues (Bug#9412).
13975 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13976 (esprintf, exprintf, evxprintf): New functions.
13977 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13978 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13979 (modify_event_symbol): Do not assume that the length of
13980 name_alist_or_stem is safe to alloca and fits in int.
13981 (Fexecute_extended_command): Likewise for function name and binding.
13982 (Frecursion_depth): Wrap around reliably on integer overflow.
13983 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13984 since some callers pass EMACS_INT values.
13985 (Fsingle_key_description): Don't crash if symbol name contains more
13986 than MAX_ALLOCA bytes.
13987 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13988 (get_minibuffer): Arg is now EMACS_INT, not int.
13989 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13990 (esprintf, exprintf, evxprintf): New decls.
13991 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13993 * dbusbind.c (signature_cat): New function.
13994 (xd_signature, Fdbus_register_signal):
13995 Do not overrun buffer; instead, report string overflow.
13997 * dispnew.c (add_window_display_history): Don't overrun buffer.
13998 Truncate instead; this is OK since it's just a log.
14000 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14001 even if the time zone offset is outlandishly large.
14002 Don't mishandle offset == INT_MIN.
14004 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14005 when creating daemon; the previous buffer-overflow check was incorrect.
14007 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14008 which has the guts of the old verror function.
14010 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14011 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14013 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14014 (font_unparse_xlfd): Don't blindly alloca long strings.
14015 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14016 fits in int, when using sprintf. Use single snprintf to count
14017 length of string rather than counting it via multiple sprintfs;
14018 that's simpler and more reliable.
14019 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14020 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14021 sprintf, in case result does not fit in int.
14023 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14024 (fontset_from_font): Print it.
14026 * frame.c (tty_frame_count): Now printmax_t, not int.
14027 (make_terminal_frame, set_term_frame_name): Print it.
14028 (x_report_frame_params): In X, window IDs are unsigned long,
14029 not signed long, so print them as unsigned.
14030 (validate_x_resource_name): Check for implausibly long names,
14031 and don't assume name length fits in 'int'.
14032 (x_get_resource_string): Don't blindly alloca invocation name;
14033 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14036 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14037 (xg_check_special_colors, xg_set_geometry):
14038 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14040 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14041 Use esprintf, not sprintf, in case result does not fit in int.
14043 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14044 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14045 it as a large positive number.
14046 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14047 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14049 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14050 in case result does not fit in int.
14052 * print.c (float_to_string): Detect width overflow more reliably.
14053 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14054 buffer overrun. Don't assume list length fits in 'int'. Treat
14055 print length of 0 as 0, not as infinity; to be consistent with other
14056 uses of print length in this function. Don't overflow print length
14057 index. Don't assume hash table size fits in 'long', or that
14058 vectorlike size fits in 'unsigned long'.
14060 * process.c (make_process): Use printmax_t, not int, to format
14061 process-name gensyms.
14063 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14065 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14066 to avoid potential buffer overrun.
14068 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14069 if X resource line is longer than 512 bytes.
14071 * xfns.c (x_window): Make sprintf buffer a bit bigger
14072 to avoid potential buffer overrun.
14074 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14076 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14078 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14080 Integer overflow fixes for scrolling, etc.
14081 Without these, Emacs silently mishandles large integers sometimes.
14082 For example, "C-u 4294967297 M-x recenter" was treated as if
14083 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14085 * xdisp.c (try_window_id): Check Emacs fixnum range before
14086 converting to 'int'.
14088 * window.c (window_scroll_line_based, Frecenter):
14089 Check that an Emacs fixnum is in range before assigning it to 'int'.
14090 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14091 values converted from Emacs fixnums.
14092 (Frecenter): Don't wrap around a line count if it is out of 'int'
14093 range; instead, treat it as an extreme value.
14094 (Fset_window_configuration, compare_window_configurations):
14095 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14097 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14098 that can exceed INT_MAX. Check that EMACS_INT value is in range
14099 before assigning it to the (possibly-narrower) index.
14100 (match_limit): Don't assume that a fixnum can fit in 'int'.
14102 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14105 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14106 (Fvertical_motion): Don't wrap around LINES values that don't fit
14107 in 'int'. Instead, treat them as extreme values. This is good
14108 enough for windows, which can't have more than INT_MAX lines anyway.
14110 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14112 * Require libxml/parser.h to avoid compilation warning.
14114 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14116 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14117 since this reportedly can destroy thread storage.
14119 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14121 * syntax.c (find_defun_start): Update all cache variables if
14122 exiting early (Bug#9401).
14124 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14126 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14128 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14129 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14130 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14132 * term.c (tty_append_glyph): New function.
14133 (produce_stretch_glyph): Static function and its prototype deleted.
14135 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14138 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14140 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14141 when checking :margin (Bug#9390).
14142 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14143 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14144 so that the name doesn't mislead. All uses changed.
14146 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14148 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14151 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14153 * xdisp.c (move_it_to): Don't bail out early when reaching
14154 position beyond to_charpos, if we are scanning backwards.
14155 (move_it_vertically_backward): When DY == 0, make sure we get to
14156 the first character in the line after the newline.
14158 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14160 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14161 (ccl_driver): Do not generate an out-of-range pointer.
14162 (Fccl_execute_on_string): Remove unnecessary check for
14163 integer overflow, noted by Stefan Monnier in
14164 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14165 Remove a FIXME that didn't need fixing.
14166 Simplify the newly-introduced buffer reallocation code.
14168 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14170 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14172 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14174 Integer and memory overflow issues (Bug#9196).
14176 * doc.c (get_doc_string): Rework so that
14177 get_doc_string_buffer_size is the actual buffer size, rather than
14178 being 1 less than the actual buffer size; this makes xpalloc more
14181 * image.c (x_allocate_bitmap_record, cache_image):
14182 * xselect.c (Fx_register_dnd_atom):
14183 Simplify previous changes by using xpalloc.
14185 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14186 since either will do and ptrdiff_t is convenient with xpalloc.
14188 * charset.c (charset_table_size)
14189 (struct charset_sort_data.priority): Now ptrdiff_t.
14190 (charset_compare): Don't overflow if priorities differ greatly.
14191 (Fsort_charsets): Don't assume list length fits in int.
14192 Check for size-calculation overflow when allocating sort data.
14193 (syms_of_charset): Allocate an initial charset table that is
14194 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14196 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14198 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14199 The actual value is always <= INT_MAX, and leaving it unsigned made
14200 overflow checking harder.
14202 * dispextern.h (struct glyph_matrix.rows_allocated)
14203 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14204 with xpalloc. The values are still always <= INT_MAX.
14206 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14208 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14209 (SAFE_NALLOCA): New macro.
14211 * region-cache.c (struct boundary.pos, find_cache_boundary)
14212 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14213 (set_cache_region, invalidate_region_cache)
14214 (revalidate_region_cache, know_region_cache, region_cache_forward)
14215 (region_cache_backward, pp_cache):
14216 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14217 so that ptrdiff_t * can be passed to xpalloc.
14218 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14219 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14220 (pp_cache): Don't assume cache_len fits in int.
14221 * region-cache.h: Adjust extern decls to match.
14223 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14224 EMACS_INT, since either will do, for xpalloc.
14226 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14227 (xnmalloc, xnrealloc, xpalloc): New functions.
14229 * bidi.c (bidi_shelve_header_size): New constant.
14230 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14231 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14233 * bidi.c (bidi_cache_shrink):
14234 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14236 Don't update size of array until after memory allocation succeeds,
14237 because xmalloc/xrealloc may not return.
14238 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14239 now that we have proper integer overflow checking.
14240 (record_overlay_string, overlay_strings): Catch overflows when
14241 calculating size of overlay_str_buf.
14243 * callproc.c (Fcall_process): Check for size overflow when
14244 calculating size of args2.
14245 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14246 Normally we prefer signed values, but sticking with ptrdiff_t would
14247 require adding more-complicated checks.
14249 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14250 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14251 Redo buffer-overflow calculations to avoid integer overflow.
14252 Add a FIXME comment where memory seems to be over-allocated.
14254 * character.c (Fstring): Check for size-calculation overflow.
14256 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14257 unnecessary integer overflow. Check for size overflow.
14258 (encode_coding_object): Don't update size until xmalloc succeeds.
14260 * composite.c (get_composition_id): Check for overflow in glyph
14261 length calculations.
14263 Integer and memory overflow fixes for display code.
14264 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14265 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14266 (scrolling_window): Check for overflow in size calculations.
14267 (line_draw_cost, realloc_glyph_pool, add_row_entry):
14268 Don't assume glyph table len fits in int.
14269 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
14270 (row_table_size): Now ptrdiff_t, not int.
14271 (scrolling_window): Avoid overflow in size calculations.
14272 Don't update size until allocation succeeds.
14273 * fns.c (concat): Check for overflow in size calculations.
14274 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14275 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
14276 (NEXT_ALMOST_PRIME_LIMIT): New constant.
14278 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14279 (get_doc_string): Check for size calculation overflow.
14280 Don't update size until allocation succeeds.
14281 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14282 EMACS_INT, where ptrdiff_t will do.
14283 (Fsubstitute_command_keys): Check for string overflow.
14285 * editfns.c (set_time_zone_rule): Don't assume environment length
14287 (message_length): Now ptrdiff_t, not int.
14288 (Fmessage_box): Don't update size until allocation succeeds.
14289 Don't assume message length fits in int.
14290 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14292 * emacs.c (main): Do not reallocate argv, since there is a null at
14293 the end that can be overwritten, and this way there's no need to
14294 worry about size-calculation overflow.
14295 (sort_args): Check for size-calculation overflow.
14297 * eval.c (init_eval_once, grow_specpdl): Don't update size until

14303 Check for integer overflow.
14304 (x_set_alpha): Do not assume XINT fits in int.
14306 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14307 This is for the members text_lines, text_cols, total_lines, total_cols,
14308 where the system imposes an 'int' limit.
14310 * fringe.c (Fdefine_fringe_bitmap):

14317 Check for size-calculation overflow.
14318 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14319 do, as we prefer signed integers.
14320 (id_to_widget.max_size, id_to_widget.used)
14321 (xg_store_widget_in_map, xg_remove_widget_from_map)

14375 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14376 for command line length. Do not attempt to address one before the
14377 beginning of an array, as that's not portable.

14407 Check for size calculation overflow.
14408 (cache_face): Treat size calculation overflows as if they were
14409 memory exhaustion (the usual treatment), rather than aborting.
14411 * xfns.c (x_encode_text, x_set_name_internal)
14412 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14413 sizes, since they can exceed INT_MAX in size. Check for size
14414 calculation overflow.
14416 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
14417 (xg_select): Check for size calculation overflow.
14418 Don't update size until alloc done.
14420 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14421 as sprintf is limited to int lengths.
14423 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14424 (X_LONG_MIN): New macros.
14425 Use them to make the following changes clearer.
14426 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14427 This change doesn't affect the value now, but it may help remind
14428 future maintainers not to raise the value too much later.
14429 (SELECTION_QUANTUM): Remove, replacing with ...
14430 (selection_quantum): ... new function, which avoids overflow.
14432 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14433 assumption that selection length fits in 'int'.

14450 Don't store size until memory allocation succeeds.
14451 (x_get_window_property): Plug memory leak on memory exhaustion.
14452 Don't double-block input; malloc is safe here. Don't assume 2**34
14453 - 4 fits in unsigned long. Add an xassert to check
14454 XGetWindowProperty overflow. Be more careful about overflow
14455 calculations, and distinguish size from memory overflow better.
14456 (receive_incremental_selection): When tracing, don't assume
14457 unsigned int is less than INT_MAX.
14458 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

14461 in the range -65535 through -1 fit in an X unsigned short.
14462 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14463 result parameters unless successful. Rely on cons_to_unsigned
14464 to report problems with elements; the old code wasn't right anyway.
14465 (x_check_property_data): Check for int overflow; we cannot use
14466 a wider type due to X limits.
14467 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

14499 * lisp.h (hash_lookup, hash_put):
14500 * minibuf.c (Ftest_completion):
14501 Use ptrdiff_t for hash table indexes, not int (which is too
14502 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14503 32-bit --with-wide-int hosts).
14505 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14506 Add a FIXME comment about memory leaks.
14507 (syms_of_charset): Don't assume xmalloc returns.

14514 with outlandish widths.
14515 * character.h (sanitize_tab_width): Rename from sanitize_width,
14516 now that we have two such functions. All uses changed.

14534 * xterm.c: Don't go over XClientMessageEvent limit.
14535 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14536 (x_send_scroll_bar_event): Likewise. Check that the size does not
14537 exceed limits imposed by XClientMessageEvent, as well as the usual
14538 ptrdiff_t and size_t limits.
14540 * keyboard.c: Overflow, signedness and related fixes.
14541 (make_lispy_movement): Use same integer type in forward decl
14542 that is used in the definition.
14543 (read_key_sequence, keyremap_step):
14544 Change bufsize argument back to int, undoing my 2011-03-30 change.
14545 We prefer signed types, and int is wide enough here.
14546 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14547 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14548 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14549 length, not size_t. Use ptrdiff_t for index, not int.
14550 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14551 possibility of integer overflow.
14553 Overflow, signedness and related fixes for images.

14575 (lookup_image): Remove unnecessary tests.
14576 (xbm_image_p): Locals are now of int, not EMACS_INT,
14577 since parse_image_check makes sure they fit into int.
14578 (png_load, gif_load, svg_load_image):
14579 Prefer int to unsigned where either will do.
14580 (tiff_handler): New function, combining the cores of the
14581 old tiff_error_handler and tiff_warning_handler.
14582 This function is rewritten to use vsnprintf and thereby avoid
14583 stack buffer overflows. It uses only the features of vsnprintf
14584 that are common to both POSIX and native Microsoft.
14585 (tiff_error_handler, tiff_warning_handler): Use it.
14586 (tiff_load, gif_load, imagemagick_load_image):
14587 Don't assume :index value fits in 'int'.
14588 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14589 (imagemagick_load_image): Check that crop parameters fit into
14590 the integer types that MagickCropImage accepts. Don't assume
14591 Vimagemagick_render_type has a nonnegative value. Don't assume
14592 size_t fits in 'long'.
14593 (gs_load): Use printmax_t to print the widest integers possible.
14594 Check for integer overflow when computing image height and width.

14606 handle_single_display_spec, not just 1 or zero.
14607 (handle_single_display_spec): If the display spec is of the form
14608 `(space ...)', and specifies display in the text area, return 2
14610 (try_cursor_movement): Check for the need to scroll more
14611 accurately, and prefer exact match for point under bidi.
14612 Don't advance `row' beyond the last row of the window.

14630 buffers, return left-to-right.
14631 (set_cursor_from_row): Consider candidate row a win if its glyph
14632 represents a newline and point is on that newline. Fixes cursor
14633 positioning on the newline at EOL of R2L text within L2R
14634 paragraph, and vice versa.
14635 (try_cursor_movement): Check continued rows, in addition to
14636 continuation rows. Fixes unwarranted scroll when point enters a
14637 continued line of R2L text within an L2R paragraph, or vice versa.
14638 (cursor_row_p): Consider the case of point being equal to
14639 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14640 from the end of a short line to the beginning of a continued line
14641 of R2L text within L2R paragraph.
14642 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

14665 * xdisp.c (redisplay_window): When computing centering_position,
14666 account for the height of the header line. (Bug#8874)
14668 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14669 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14670 candidate is selected by the mouse, and that candidate has a
14671 composed character under the mouse.
14673 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14674 coordinates reported by pos-visible-in-window-p for a composed
14675 character in column zero.
14677 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

14681 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14683 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14684 consider it a hit if to_charpos is anywhere in the range of the
14685 composed buffer positions.
14687 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14689 * image.c (gif_load): Don't assume that each subimage has the same
14690 dimensions as the base image. Handle disposal method that is
14691 "undefined" by the gif spec (Bug#9335).
14693 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14695 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14700 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14701 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14702 from an Org mode buffer to a Speedbar frame.
14704 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14705 a composition, take its buffer position from IT->cmp_it.charpos.
14706 Fixes cursor positioning at the beginning of a line that begins
14707 with a composed character.
14709 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14711 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14712 character bidirectional type, use STRONG_L instead. Fixes crashes
14713 in a buffer produced by `describe-categories'.
14715 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14716 members before the level stack, so they would be saved and
14717 restored when copying iterator state. Fixes incorrect reordering
14718 around TABs covered by display properties.
14720 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

14733 has no `load' handler, try opening the file locally. (Bug#9311)
14735 2011-08-16 Ken Brown <kbrown@cornell.edu>
14737 * gmalloc.c: Expand comment.
14739 2011-08-16 Eli Zaretskii <eliz@gnu.org>
14741 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
14742 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
14744 2011-08-16 Ken Brown <kbrown@cornell.edu>
14746 Fix memory allocation problems in Cygwin build (Bug#9273).
14748 * unexcw.c ( __malloc_initialized): Declare external variable.
14749 (fixup_executable): Force the dumped emacs to reinitialize malloc.
14751 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
14753 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
14755 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
14756 in the static heap.
14757 [CYGWIN] (special_realloc): New function.
14758 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
14759 requests to realloc storage in the static heap.
14761 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
14763 * bidi.c (bidi_initialize): Remove unused local.
14765 2011-08-15 Eli Zaretskii <eliz@gnu.org>
14768 * biditype.h: Remove file.
14769 * makefile.w32-in ($(BLD)/bidi.$(O)):
14770 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
14772 * dispextern.h: Fix a typo in the comment to bidi_type_t.
14774 * chartab.c: Improve commentary for the uniprop_table API.
14776 * bidi.c (bidi_paragraph_init): Support zero value of
14777 bidi_ignore_explicit_marks_for_paragraph_level.
14778 (bidi_initialize): Use uniprop_table instead of including
14779 biditype.h and bidimirror.h.
14781 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
14782 coordinates of the iterator when restoring from ppos_it.
14785 2011-08-14 Kenichi Handa <handa@m17n.org>
14787 * process.c (create_process): Call setup_process_coding_systems
14788 after the pid of the process is set to -1 (Bug#8162).
14790 2011-08-14 Eli Zaretskii <eliz@gnu.org>
14792 * xdisp.c (move_it_in_display_line_to): Don't invoke
14793 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14794 ppos_it. Fixes vertical cursor motion when line beginning is
14795 covered by an image. (Bug#9296)
14797 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14799 * nsterm.h (ns_run_ascript): Declare.
14800 (NSAPP_DATA2_RUNASSCRIPT): Define.
14802 * nsfns.m (as_script, as_result, as_status): New static variables.
14803 (ns_run_ascript): New function.
14804 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14805 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14806 the event loop. Get status from as_status (Bug#7276).
14808 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14809 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14810 the event loop (Bug#7276).
14812 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14814 * gnutls.c (QCgnutls_bootprop_priority)
14815 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
14816 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
14817 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
14818 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
14819 (QCgnutls_bootprop_verify_hostname_error)
14820 (QCgnutls_bootprop_callbacks_verify): Rename from
14821 Qgnutls_bootprop_..., all uses changed.
14823 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
14826 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
14828 * xfaces.c (Qframe_set_background_mode): Now static.
14829 * dispextern.h (Qframe_set_background_mode): Remove decl.

14833 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
14835 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
14836 (Fnetwork_interface_list): Allocate in increments of bytes instead
14837 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14838 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14840 (struct ifflag_def): notrailers is smart on OSX.
14841 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14842 Get hardware address with getifaddrs if available.
14844 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14846 * xdisp.c (iterate_out_of_display_property): xassert that
14847 IT->position is set to within IT->object's boundaries. Break from
14848 the loop as soon as EOB is reached; avoids infloops in redisplay
14849 when IT->position is set up wrongly due to some bug.
14850 Set IT->current to match the bidi iterator unconditionally.
14851 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14852 entry. Force push_it to save on the stack the current
14853 buffer/string position, to be restored by pop_it. Fix flags in
14854 the iterator structure wrt the object coming from a display
14855 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14856 properties. (Bug#9284)
14858 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14860 * fontset.c (fontset_get_font_group): Add proper type checks.
14863 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14865 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
14866 and LC_VERSION_MIN_MACOSX.
14867 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
14868 (dump_it) [LC_FUNCTION_STARTS]: Use it.
14870 2011-08-08 Eli Zaretskii <eliz@gnu.org>
14872 * xdisp.c (forward_to_next_line_start): Allow to use the
14873 no-display-properties-and-no-overlays under bidi display.
14874 Set disp_pos in the bidi iterator to avoid searches for display
14875 properties and overlays.
14877 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14879 * editfns.c (Fset_time_zone_rule): Document relationship with the
14882 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
14883 the font entity extracted from the cache (Bug#8109).
14885 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14887 * composite.c (autocmp_chars): Don't reset point. That is done by
14888 restore_point_unwind (Bug#5984).
14890 2011-08-07 Juri Linkov <juri@jurta.org>
14892 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14893 to show the arg `TIME' instead of `TIMEVAL'.
14895 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14897 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14898 display property strides EOL and includes a newline, as in
14899 longlines-mode. (Bug#9254)
14900 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14901 word-wrap under bidirectional display. (Bug#9224)
14903 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14904 is non-zero, even if the data buffer is NULL. Fixes a crash in
14905 vertical-motion with longlines-mode. (Bug#9254)
14907 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14909 * bidi.c <bidi_cache_total_alloc>: Now static.
14910 (bidi_initialize): Initialize bidi_cache_total_alloc.
14912 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14915 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14916 amount allocated this far in `bidi_cache_total_alloc'.
14917 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14918 non-zero, only free the data buffer without restoring the cache
14919 contents. All callers changed.
14921 * dispextern.h (bidi_unshelve_cache): Update prototype.
14923 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14924 (move_it_in_display_line, move_it_to)
14925 (move_it_vertically_backward, move_it_by_lines): Replace the call
14926 to xfree to an equivalent call to bidi_unshelve_cache.
14927 (move_it_in_display_line_to): Fix logic of returning
14928 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14930 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14932 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14933 came from a string character with a `cursor' property. (Bug#9229)
14935 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14937 * Makefile.in (LIB_PTHREAD): New variable.
14938 (LIBES): Add LIB_PTHREAD (Bug#9216).
14940 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14941 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14943 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14945 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14947 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14949 * xterm.c (x_find_topmost_parent): New function.
14950 (x_set_frame_alpha): Find topmost parent window with
14951 x_find_topmost_parent and set the property there also (bug#9181).
14952 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14954 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14956 * callproc.c (Fcall_process): Avoid vfork clobbering
14957 the local vars buffer, coding_systems, current_dir.
14959 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14961 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14963 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14965 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14966 so that it is not optimized away.
14968 * xdisp.c (compute_display_string_pos): Remove unused local.
14970 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14972 Fix slow cursor motion and scrolling in large buffers with
14973 selective display, like Org Mode buffers. (Bug#9218)
14975 * dispextern.h (struct bidi_it): New member disp_prop_p.
14977 * xdisp.c: Remove one-slot cache of display string positions.
14978 (compute_display_string_pos): Accept an additional argument
14979 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14980 for a display string or property. If found, set DISP_PROP_P
14983 * bidi.c (bidi_fetch_char): Accept an additional argument
14984 DISP_PROP_P, and pass it to compute_display_string_pos.
14985 Only handle text covered by a display string if DISP_PROP_P is returned
14986 non-zero. All callers of bidi_fetch_char changed.
14988 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14990 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14992 2010-12-03 Don March <don@ohspite.net>
14994 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14995 last character M-[char] is translated to ESC [char] (bug#7541).
14997 2011-08-02 Kenichi Handa <handa@m17n.org>
14999 * lisp.h (uniprop_table): Extern it.
15001 * chartab.c (uniprop_table): Make it non-static.
15003 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15005 * xdisp.c (forward_to_next_line_start): Accept additional argument
15006 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15008 (reseat_at_next_visible_line_start): Use the bidi iterator state
15009 returned by forward_to_next_line_start to restore the state of
15010 it->bidi_it after backing up to previous newline. (Bug#9212)
15012 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15014 * regex.c (re_comp): Protoize.
15015 (re_exec): Fix return type.
15016 (regexec): Fix type of `ret'. (Bug#9203)
15018 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15020 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15021 This is needed if max-image-size is a floating-point number.
15023 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15025 * print.c (print_object): Print empty symbol as ##.
15027 * lread.c (read1): Read ## as empty symbol.
15029 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15031 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15032 setting frame foreground color (Bug#9175).
15033 (x_set_background_color): Likewise.
15035 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15036 contents (Bug#9176).
15037 (EmacsTooltip -init): Remove bezels and add shadows to
15040 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15041 or scroll bar (Bug#8470).
15043 * nsfont.m (nsfont_open): Remove assignment to voffset and
15044 unnecessary vars hshink, expand, hd, full_height, min_height.
15045 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15047 * nsterm.h (nsfont_info): Remove voffset field.
15049 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15051 Implement strike-through and overline on NextStep (Bug#8863).
15053 * nsfont.m (nsfont_open): Use underline position provided by font,
15054 instead of hard-coded value of 2.
15055 (nsfont_draw): Call ns_draw_text_decoration instead.
15057 * nsterm.h: Add declaration for ns_draw_text_decoration.
15059 * nsterm.m (ns_draw_text_decoration): New function for drawing
15060 underline, overline, and strike-through.
15061 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15062 ns_draw_text_decoration. Change treatment of cursor drawing to
15063 accommodate underlining, etc.
15065 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15067 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15070 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15072 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15073 Without this fix, if a signal arrives just after memory fills up,
15074 'malloc' might be invoked reentrantly.
15076 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15077 In other words, assume that every image size is allowed, on non-X
15078 hosts. This assumption is probably wrong, but it lets Emacs compile.
15080 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15082 * regex.c (re_iswctype): Convert return values to boolean.
15084 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15086 * xdisp.c (compute_display_string_pos): Don't use cached display
15087 string position if the buffer had its restriction changed.
15090 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15092 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15094 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15096 Integer signedness and overflow and related fixes. (Bug#9079)
15098 * bidi.c: Integer size and overflow fixes.
15099 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15100 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15101 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15102 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15103 (bidi_find_other_level_edge):
15104 Use ptrdiff_t instead of EMACS_INT where either will do.
15105 This works better on 32-bit hosts configured --with-wide-int.
15106 (bidi_cache_ensure_space): Check for size-calculation overflow.
15107 Use % rather than repeated addition, for better worst-case speed.
15108 Don't set bidi_cache_size until after xrealloc returns, because it
15110 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15111 (bidi_cache_ensure_space): Also check that the bidi cache size
15112 does not exceed that of the largest Lisp string or buffer. See Eli
15113 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15115 * alloc.c (__malloc_size_t): Remove.
15116 All uses replaced by size_t. See Andreas Schwab's note
15117 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15119 * image.c: Improve checking for integer overflow.
15120 (check_image_size): Assume that f is nonnull, since
15121 it is always nonnull in practice. This is one less thing to
15122 worry about when checking for integer overflow later.
15123 (x_check_image_size): New function, which checks for integer
15124 overflow issues inside X.
15125 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15126 This removes the need for a memory_full check.
15127 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15128 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15129 (xbm_read_bitmap_data): Change locals back to 'int', since
15130 their values must fit in 'int'.
15131 (xpm_load_image, png_load, tiff_load):
15132 Invoke x_create_x_image_and_pixmap earlier,
15133 to avoid much needless work if the image is too large.
15134 (tiff_load): Treat overly large images as if
15135 x_create_x_image_and_pixmap failed, not as malloc failures.
15136 (gs_load): Use x_check_image_size.
15138 * gtkutil.c: Omit integer casts.
15139 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15140 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15142 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15144 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15145 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15146 would wrongly return t on a 64-bit host.
15148 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15149 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15150 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15151 and therefore cause GCC to emit a bogus diagnostic in some cases.
15153 * image.c: Integer signedness and overflow and related fixes.
15154 This is not an exhaustive set of fixes, but it's time to
15155 record what I've got.
15156 (lookup_pixel_color, check_image_size): Remove redundant decls.
15157 (check_image_size): Don't assume that arbitrary EMACS_INT values
15158 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15159 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15160 (tiff_load, imagemagick_load_image):
15161 Check for overflow in size calculations.
15162 (x_create_x_image_and_pixmap): Remove unnecessary test for
15163 xmalloc returning NULL; that can't happen.
15164 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15165 (xpm_color_bucket): Use better integer hashing function.
15166 (xpm_cache_color): Don't possibly over-allocate memory.
15167 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15168 (gif_memory_source):
15169 Use ptrdiff_t, not int or size_t, to record sizes.
15170 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15171 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15172 either works, as we prefer signed integers.
15173 (tiff_read_from_memory, tiff_write_from_memory):
15174 Return tsize_t, not size_t, since that's what the TIFF API wants.
15175 (tiff_read_from_memory): Don't fail simply because the read would
15176 go past EOF; instead, return a short read.
15177 (tiff_load): Omit no-longer-needed casts.
15178 (Fimagemagick_types): Don't assume size fits into 'int'.
15180 Improve hashing quality when configured --with-wide-int.
15181 * fns.c (hash_string): New function, taken from sxhash_string.
15182 Do not discard information about ASCII character case; this
15183 discarding is no longer needed.
15184 (sxhash-string): Use it. Change sig to match it. Caller changed.
15185 * lisp.h: Declare it.
15186 * lread.c (hash_string): Remove, since we now use fns.c's version.
15187 The fns.c version returns a wider integer if --with-wide-int is
15188 specified, so this should help the quality of the hashing a bit.
15190 * emacs.c: Integer overflow minor fix.
15191 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15192 Define only if GNU_LINUX.
15193 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15195 * dispnew.c: Integer signedness and overflow fixes.
15196 Remove unnecessary forward decls, that were a maintenance hassle.
15197 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15199 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15200 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15201 (prepare_desired_row, line_draw_cost):
15202 Use int, not unsigned, where either works.
15203 (save_current_matrix, restore_current_matrix):
15204 Use ptrdiff_t, not size_t, where either works.
15205 (init_display): Check for overflow more accurately, and without
15206 relying on undefined behavior.
15208 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15209 Remove, replacing with the new symbols in lisp.h. All uses changed.
15210 * fileio.c (make_temp_name):
15211 * filelock.c (lock_file_1, lock_file):
15212 * xdisp.c (message_dolog):
15213 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15214 Use pMd etc. instead.
15215 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15216 replacing the pWIDE etc. symbols removed from editfns.c.
15218 * keyboard.h (num_input_events): Now uintmax_t.
15219 This is (very slightly) less likely to mess up due to wraparound.
15222 * buffer.c: Integer signedness fixes.
15223 (alloc_buffer_text, enlarge_buffer_text):
15224 Use ptrdiff_t rather than size_t when either will do, as we prefer
15227 * alloc.c: Integer signedness and overflow fixes.
15228 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15229 (__malloc_size_t): Default to size_t, not to int.
15230 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15231 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15232 Prefer ptrdiff_t to size_t when either would do, as we prefer
15234 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15235 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15236 Now const. Initialize with values that are in range even if char
15238 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15239 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15240 These functions do the right thing with sizes > 2**32.
15241 (check_depth): Now ptrdiff_t, not int.
15242 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15243 Adjust to new way of storing sizes. Check for size overflow bugs
15245 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15246 slightly wrong anyway, as it missed one instance of
15247 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15248 (refill_memory_reserve): Omit needless cast to size_t.
15249 (mark_object_loop_halt): Mark as externally visible.
15251 * xselect.c: Integer signedness and overflow fixes.
15252 (Fx_register_dnd_atom, x_handle_dnd_message):
15253 Use ptrdiff_t, not size_t, since we prefer signed.
15254 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15255 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15256 x_dnd_atoms_size and x_dnd_atoms_length.
15258 * doprnt.c: Prefer signed to unsigned when either works.
15260 * doprnt.c (doprnt):
15262 * xdisp.c (vmessage):
15263 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15264 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15265 prefer signed arithmetic to avoid comparison confusion.
15266 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15267 but is a bit tricky.
15269 Assume freestanding C89 headers, string.h, stdlib.h.
15270 * data.c, doprnt.c, floatfns.c, print.c:
15271 Include float.h unconditionally.
15272 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15273 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15274 * regex.c: Likewise for stddef.h, string.h.
15275 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15276 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15277 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15278 (STDC_HEADERS): Remove obsolete defines.
15279 * sysdep.c: Include limits.h unconditionally.
15281 Assume support for memcmp, memcpy, memmove, memset.
15282 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15283 * regex.c (memcmp, memcpy):
15284 Remove; we assume C89 now.
15286 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15287 (__malloc_safe_bcopy): Remove; no longer needed.
15289 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15290 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15291 well either way, and we prefer signed to unsigned.
15293 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15295 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15296 closes the connection while we're reading (bug#9182).
15298 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15300 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15301 are specified (Bug#9168).
15303 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15305 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15306 Found by GCC static checking and --with-wide-int on a 32-bit host.
15308 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15310 * xdisp.c (compute_display_string_pos): Fix logic of caching
15311 previous display string position. Initialize cached_prev_pos to
15312 -1. Fixes slow-down at the beginning of a buffer.
15314 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15316 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15317 for attrs[LFACE_FONTSET_INDEX].
15319 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15321 * xml.c (parse_region): Remove unused local
15322 that was recently introduced.
15324 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15326 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15327 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15329 * xdisp.c (move_it_in_display_line_to): Record the best matching
15330 position for TO_CHARPOS while scanning the line, and restore it on
15331 exit if none of the characters scanned was an exact match.
15332 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15333 when exact match is impossible due to invisible text, and the
15334 lines are truncated.
15336 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15338 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15341 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15343 Fix a significant slow-down of cursor motion with C-n, C-p,
15344 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15345 auto-repeat under bidi redisplay in fontified buffers.
15346 * xdisp.c (compute_stop_pos_backwards): New function.
15347 (next_element_from_buffer): Call compute_stop_pos_backwards to
15348 find a suitable prev_stop when we find ourselves before
15350 (reseat): Don't look for prev_stop, as that could mean a very long
15352 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15353 <cached_disp_overlay_modiff>: Cache for last found display string
15355 (compute_display_string_pos): Return the cached position if asked
15356 about the same buffer in the same area of character positions, and
15357 the buffer wasn't changed since the time the display string
15358 position was cached.
15360 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15362 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15363 is an integer, which is important for empty lines. (Bug#9149)
15365 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15367 * frame.c (Fmodify_frame_parameters): In tty case, update the
15368 default face if necessary (Bug#4238).
15370 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15372 * editfns.c (Fstring_to_char): No need to explain what a character
15373 is in the docstring (Bug#6576).
15375 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15377 * xml.c (parse_region): Make sure we always return a tree.
15379 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15381 * xml.c (parse_region): If a document contains only comments,
15384 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15386 * xml.c (make_dom): Return comments, too.
15388 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15391 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15392 and the surrounding thread.
15393 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15394 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15395 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15397 * s/openbsd.h (BROKEN_SIGIO): Define.
15398 * unexelf.c (unexec) [__OpenBSD__]:
15399 Don't update the .mdebug section of the Alpha COFF symbol table.
15401 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15403 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15406 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15408 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15409 This fixes some race conditions on the permissions of any newly
15412 * alloc.c (valid_pointer_p): Use pipe, not open.
15413 This fixes some permissions issues when debugging.
15415 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15416 If fchown fails to set both uid and gid, try to set just gid,
15417 as that is sometimes allowed. Adjust the file's mode to eliminate
15418 setuid or setgid bits that are inappropriate if fchown fails.
15420 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15422 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15423 to compare Lisp_Objects.
15424 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15425 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15426 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15428 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15430 * lread.c (read_integer): Unread even EOF character.
15431 (read1): Likewise. Properly record start position of symbol.
15433 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15434 symbol character follows.
15436 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15438 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15439 This works around a problem with the previous change to Fcopy_file.
15440 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15441 and without this change, GCC might complain about discarding
15442 fchown's return value.
15444 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15446 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15448 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15450 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15452 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15454 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15455 it's used from the C level.
15457 * process.c: Use the same condition for POLL_FOR_INPUT in both
15458 keyboard.c and process.c (bug#1858).
15460 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15462 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15463 (Fgnutls_boot): Use it.
15465 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15467 * doc.c (Fsubstitute_command_keys): Revert last change.
15469 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15471 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15472 quotes the next character, and doesn't affect other longer
15473 sequences (bug#8935).
15475 * lread.c (syms_of_lread): Clarify that is isn't only
15476 `eval-buffer' and `eval-defun' that's affected by
15477 `lexical-binding' (bug#8460).
15479 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15481 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15482 bidi redisplay when a line includes both an image and is truncated.
15484 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15486 Fix minor problems found by static checking.
15487 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15488 (elsz): Now a signed constant, not a size_t var. We prefer signed
15489 types to unsigned, to avoid integer comparison confusion. Without
15490 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15491 "cannot optimize loop, the loop counter may overflow", a symptom
15493 * indent.c (Fvertical_motion): Mark locals as initialized.
15494 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15496 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15498 * search.c (Fre_search_backward): Mention `case-fold-search' in
15499 all the re_search_* functions (bug#8138).
15501 * keyboard.c (Fopen_dribble_file): Document when the file is
15504 2011-07-14 Eli Zaretskii <eliz@gnu.org>
15506 * bidi.c (bidi_dump_cached_states): Fix format of displaying
15509 Support bidi reordering of display and overlay strings.

15511 (compute_display_string_end): Accept additional argument STRING.
15512 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15513 (reseat_to_string): Initialize bidi_it->string.s and
15514 bidi_it->string.schars.
15515 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15516 NULL (avoids a crash in bidi_paragraph_init).
15517 Initialize itb.string.lstring.
15518 (init_iterator): Call bidi_init_it only of a valid
15519 buffer position was specified. Initialize paragraph_embedding to
15521 (reseat_to_string): Initialize the bidi iterator.
15522 (display_string): If we need to ignore text properties of
15523 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15524 original value of -1 will not work with bidi.)
15525 (compute_display_string_pos): First arg is now struct
15526 `text_pos *'; all callers changed. Support display properties on
15528 (compute_display_string_end): Support display properties on Lisp
15530 (init_iterator, reseat_1, reseat_to_string): Initialize the
15531 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15532 when iterating on a string not from display properties).
15533 (compute_display_string_pos, compute_display_string_end):
15534 Fix calculation of the object to scan. Fixes an error when using
15536 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15537 base_level_stop; instead, set base_level_stop to BEGV.
15538 Fixes crashes in vertical-motion.
15539 (next_element_from_buffer): Improve commentary for when
15540 the iterator is before prev_stop.
15541 (init_iterator): Initialize bidi_p from the default value of
15542 bidi-display-reordering, not from buffer-local value. Use the
15543 buffer-local value only if initializing for buffer iteration.
15544 (handle_invisible_prop): Support invisible properties on strings
15545 that are being bidi-reordered.
15546 (set_iterator_to_next): Support bidi reordering of C strings and
15548 (next_element_from_string): Support bidi reordering of Lisp
15550 (handle_stop_backwards): Support Lisp strings as well.
15551 (display_string): Support display of R2L glyph rows.
15552 Use IT_STRING_CHARPOS when displaying from a Lisp string.
15553 (init_iterator): Don't initialize it->bidi_p for strings
15555 (reseat_to_string): Initialize it->bidi_p for strings here.
15556 (next_element_from_string, next_element_from_c_string)
15557 (next_element_from_buffer): Add xassert's for correspondence
15558 between IT's object being iterated and it->bidi_it.string
15560 (face_before_or_after_it_pos): Support bidi iteration.
15561 (next_element_from_c_string): Handle the case of the first string
15562 character that is not the first one in the visual order.
15563 (get_visually_first_element): New function, refactored from common
15564 parts of next_element_from_buffer, next_element_from_string, and
15565 next_element_from_c_string.
15566 (tool_bar_lines_needed, redisplay_tool_bar)
15567 (display_menu_bar): Force left-to-right direction. Add a FIXME
15568 comment for making that be controlled by a user option.
15569 (push_it, pop_it): Save and restore the state of the
15570 bidi iterator. Save and restore the bidi_p flag.
15571 (pop_it): Iterate out of display property for string iteration as
15573 (iterate_out_of_display_property): Support iteration over strings.
15574 (handle_single_display_spec): Set up it->bidi_it for iteration
15575 over a display string, and call bidi_init_it.
15576 (handle_single_display_spec, next_overlay_string)
15577 (get_overlay_strings_1, push_display_prop): Set up the bidi
15578 iterator for displaying display or overlay strings.
15579 (forward_to_next_line_start): Don't use the shortcut if
15581 (back_to_previous_visible_line_start): If handle_display_prop
15582 pushed the iterator stack, restore the internal state of the bidi
15583 iterator by calling bidi_pop_it same number of times.
15584 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15585 and we are bidi-iterating, don't decrement the iterator position;
15586 instead, set the first_elt flag in the bidi iterator, to produce
15588 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15589 (push_display_prop): xassert that we are iterating a buffer.
15590 (push_it, pop_it): Save and restore paragraph_embedding member.
15591 (handle_single_display_spec, next_overlay_string)
15592 (get_overlay_strings_1, reseat_1, reseat_to_string)
15593 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15594 correctly. Don't assume unibyte strings are not bidi-reordered.
15595 (compute_display_string_pos)
15596 (compute_display_string_end): Fix handling the case of C string.
15597 (push_it, pop_it): Save and restore from_disp_prop_p.
15598 (handle_single_display_spec, push_display_prop): Set the
15599 from_disp_prop_p flag.
15600 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
15601 (pop_it): Call iterate_out_of_display_property only if we are
15602 popping after iteration over a string that came from a display
15603 property. Fix a typo in popping stretch info. Add an assertion
15604 for verifying that the iterator position is in sync with the bidi
15606 (handle_single_display_spec, get_overlay_strings_1)
15607 (push_display_prop): Fix initialization of paragraph direction for
15608 string when that of the parent object is not yet determined.
15609 (reseat_1): Call bidi_init_it to resync the bidi
15610 iterator with IT's position. (Bug#7616)
15611 (find_row_edges): If ROW->start.pos gives position
15612 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
15613 (handle_stop, back_to_previous_visible_line_start, reseat_1):
15614 Reset the from_disp_prop_p flag.
15615 (SAVE_IT, RESTORE_IT): New macros.
15616 (pos_visible_p, face_before_or_after_it_pos)
15617 (back_to_previous_visible_line_start)
15618 (move_it_in_display_line_to, move_it_in_display_line)
15619 (move_it_to, move_it_vertically_backward, move_it_by_lines)
15620 (try_scrolling, redisplay_window, display_line): Use them when
15621 saving a temporary copy of the iterator and restoring it back.
15622 (back_to_previous_visible_line_start, reseat_1)
15623 (init_iterator): Empty the bidi cache "stack".
15624 (move_it_in_display_line_to): If iterator ended up at

16063 in general we prefer signed. When given a limit, use a
16064 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16065 latter isn't right if USE_2_TAGS_FOR_INTS.
16066 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16067 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16071 * textprop.c (text_property_stickiness):
16072 Obey Vtext_property_default_nonsticky.

16084 * buffer.c (Foverlay_put): Say what the return value is
16087 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16088 is a directory before asking whether to use the file name

16091 error be more correct.
16093 * fns.c (Frequire): Remove the mention of the .gz files, since
16094 that's installation-specific, but keep the mention of
16095 `get-load-suffixes'.
16097 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
16099 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

16110 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

16212 * eval.c (struct backtrace): Simplify and port the data structure.
16213 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16214 signed bit field, as this assumption is not portable and it makes
16215 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16216 "char debug_on_exit : 1" as this is not portable either; instead,
16217 use the portable "unsigned int debug_on_exit : 1". Remove unused
16218 member evalargs. Remove obsolete comments about cc bombing out.
16220 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16290 (emacs_fixed_get_preferred_height): Use min_width/height from
16291 frames size_hint to set minimum and natural (Bug#8919).
16292 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
16293 and use min_width/height from frames size_hint to set
16294 min_width/height (Bug#8919).

16314 Use gnulib's dup2 module instead of rolling our own.
16315 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

16387 (PRINTPREPARE, printchar, strout):
16388 Don't set size unless allocation succeeds.
16390 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16391 for sizes. Check for string overflow more accurately.

16405 (read_integer): Radix is now EMACS_INT, not int,
16406 to improve quality of diagnostics for out-of-range radices.
16407 Calculate buffer size correctly for out-of-range radices.
16408 (read1): Check for integer overflow in radices, and in
16409 read-circle numbers.
16410 (read_escape): Avoid int overflow.
16411 (Fload, openp, read_buffer_size, read1)
16412 (substitute_object_recurse, read_vector, read_list, map_obarray):

16435 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16436 The following patches are for when GLYPH_DEBUG && !XASSERT.
16437 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16438 * dispnew.c (flush_stdout):
16439 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16440 Mark as externally visible.
16441 * dispnew.c (check_window_matrix_pointers): Now static.
16442 * dispnew.c (window_to_frame_vpos):
16443 * xfns.c (unwind_create_frame):

16452 (debug_method_add): Use va_list and vsprintf rather than relying
16453 on undefined behavior with wrong number of arguments.
16454 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16455 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16456 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16457 since we're not interested in debugging glyphs with old libraries.
16458 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16459 GCC 4.6.0's static checking.
16461 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

16495 Use ptrdiff_t, not int, for sizes.
16496 (overlays_at, overlays_in): Check for size-calculation overflow.
16498 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16500 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16501 (x_session_initialize): Do not assume string length fits in int.
16503 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16504 This is unlikely, but can occur if DPI is outlandish.
16506 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16507 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16509 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16510 * xrdb.c (magic_file_p, search_magic_path):
16511 Omit last arg SUFFIX; it was always 0. All callers changed.
16512 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16514 * xfont.c (xfont_match): Avoid need for strlen.
16516 * xfns.c: Don't assume strlen fits in int.
16517 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16519 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16520 not unsigned long, as we prefer signed integers. All callers changed.
16521 Detect integer overflow in repeat count.
16522 (message_dolog): Don't assume print length fits in 39 bytes.
16523 (display_mode_element): Don't assume strlen fits in int.
16525 * termcap.c: Don't assume sizes fit in int and never overflow.
16526 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16527 (gobble_line): Check for size-calculation overflow.
16529 * minibuf.c (Fread_buffer):
16530 * lread.c (intern, intern_c_string):
16531 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16532 Don't assume string length fits in int.
16534 * keyboard.c (parse_tool_bar_item):
16535 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16537 * font.c: Don't assume string length fits in int.
16538 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16539 Use ptrdiff_t, not int.
16540 (font_intern_prop): Don't assume string length fits in int.
16541 Don't assume integer property fits in fixnum.
16542 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16544 * filelock.c: Fix some buffer overrun and integer overflow issues.
16545 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16546 Reformulate so as not to need the command string.
16547 Invoke gzip -cd rather than gunzip, as it's more portable.
16548 (lock_info_type, lock_file_1, lock_file):
16549 Don't assume pid_t and time_t fit in unsigned long.
16550 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16551 (current_lock_owner): Prefer signed type for sizes.
16552 Use memcpy, not strncpy, where memcpy is what is really wanted.
16553 Don't assume (via atoi) that time_t and pid_t fit in int.
16554 Check for time_t and/or pid_t out of range, e.g., via a network share.
16555 Don't alloca where an auto var works fine.
16557 * fileio.c: Fix some integer overflow issues.
16558 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16559 Don't assume string length fits in int.
16560 (directory_file_name): Don't assume string length fits in long.
16561 (make_temp_name): Don't assume pid fits in int, or that its print
16562 length is less than 20.
16564 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16566 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16568 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16570 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16571 We prefer signed integers, even for size calculations.
16573 * emacs.c: Don't assume string length fits in 'int'.
16574 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16575 (main): Don't invoke strlen when not needed.
16577 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16578 (XD_DEBUG_MESSAGE): Don't waste a byte.
16580 * callproc.c (getenv_internal_1, getenv_internal)
16581 (Fgetenv_internal):
16582 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16584 * lread.c (invalid_syntax): Omit length argument.
16585 All uses changed. This doesn't fix a bug, but it simplifies the
16586 code away from its former Hollerith-constant appearance, and it's
16587 one less 'int' to worry about when looking at integer-overflow issues.
16588 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16590 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16591 This didn't break anything, but it didn't help either.
16592 It's confusing to put a bogus integer in a place where the actual
16593 value does not matter.
16594 (LIST_END_P): Remove unused macro and its bogus comment.
16595 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16597 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16598 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16600 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16601 We prefer signed types, and the value cannot exceed the EMACS_INT
16602 range anyway (because otherwise the length would not be representable).
16603 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16604 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16605 This avoids a GCC warning when WIDE_EMACS_INT.
16607 * indent.c (sane_tab_width): New function.
16608 (current_column, scan_for_column, Findent_to, position_indentation)
16609 (compute_motion): Use it. This is just for clarity.
16610 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16612 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16614 * lisp.h (lint_assume): New macro.
16615 * composite.c (composition_gstring_put_cache):
16616 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16618 * editfns.c, insdel.c:
16619 Omit unnecessary forward decls, to simplify future changes.
16621 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16623 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16625 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16626 Use much-faster test for byte-length change.
16627 Don't assume string byte-length fits in 'int'.
16628 Check that character arg fits in 'int'.
16629 (mapcar1): Declare byte as byte, for clarity.
16631 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16633 * fns.c (concat): Catch string overflow earlier.
16634 Do not rely on integer wraparound.
16636 * dispextern.h (struct it.overlay_strings_charpos)
16637 (struct it.selective): Now EMACS_INT, not int.
16638 * xdisp.c (forward_to_next_line_start)
16639 (back_to_previous_visible_line_start)
16640 (reseat_at_next_visible_line_start, next_element_from_buffer):
16641 Don't arbitrarily truncate the value of 'selective' to int.
16643 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16645 * composite.c: Don't truncate sizes to 'int'.
16646 (composition_gstring_p, composition_reseat_it)
16647 (composition_adjust_point): Use EMACS_INT, not int.
16648 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16649 not EMACS_UINT, for indexes.
16651 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16653 * buffer.c: Include <verify.h>.
16654 (struct sortvec.priority, struct sortstr.priority):
16655 Now EMACS_INT, not int.
16656 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16657 (struct sortstr.size, record_overlay_string)
16658 (struct sortstrlist.size, struct sortlist.used):
16659 Don't truncate size to int.
16660 (record_overlay_string): Check for size-calculation overflow.
16661 (init_buffer_once): Check at compile-time, not run-time.
16663 2011-06-22 Jim Meyering <meyering@redhat.com>
16665 Don't leak an XBM-image-sized buffer
16666 * image.c (xbm_load): Free the image buffer after using it.
16668 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16671 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16672 that Sun C diagnosed.
16673 * fns.c (secure_hash): Fix pointer signedness issue.
16674 * intervals.c (static_offset_intervals): New function.
16675 (offset_intervals): Use it.
16677 2011-06-21 Leo Liu <sdl.web@gmail.com>
16680 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16683 * fns.c (secure_hash): Rename from crypto_hash_function and change
16684 the first arg to accept symbols.
16685 (Fsecure_hash): New primitive.
16686 (syms_of_fns): New symbols.
16688 2011-06-20 Deniz Dogan <deniz@dogan.se>
16690 * process.c (Fset_process_buffer): Clarify return value in
16693 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16695 * dispnew.c (add_window_display_history): Use BVAR.
16697 * xdisp.c (debug_method_add): Use BVAR.
16698 (check_window_end, dump_glyph_matrix, dump_glyph)
16699 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16701 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16704 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16705 check till after the cache is created in init_frame_faces.
16707 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16709 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16711 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16713 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16714 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16715 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16717 Improve buffer-overflow checking (Bug#8873).
16718 * fileio.c (Finsert_file_contents):
16719 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16720 Remove the old (too-loose) buffer overflow checks.
16721 They weren't needed, since make_gap checks for buffer overflow.
16722 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16723 The old code merely checked for Emacs fixnum overflow, and relied
16724 on undefined (wraparound) behavior. The new code avoids undefined
16725 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16727 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16728 Tune. Don't use wider integers than needed. Don't use alloca.
16729 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16731 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16733 * insdel.c, lisp.h (buffer_overflow): New function.
16734 (insert_from_buffer_1, replace_range, replace_range_2):
16735 * insdel.c (make_gap_larger):
16736 * editfns.c (Finsert_char):
16737 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16739 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16741 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16743 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16745 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16746 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16748 * fileio.c: Don't assume EMACS_INT fits in off_t.
16749 (emacs_lseek): New static function.
16750 (Finsert_file_contents, Fwrite_region): Use it.
16751 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16753 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16755 * fns.c: Don't overflow int when computing a list length.
16756 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16757 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16758 truncation on 64-bit hosts. Check for QUIT every
16759 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16760 faster and is responsive enough.
16761 (Flength): Report an error instead of overflowing an integer.
16762 (Fsafe_length): Return a float if the value is not representable
16763 as a fixnum. This shouldn't happen except in contrived situations.
16764 (Fnthcdr, Fsort): Don't assume list length fits in int.
16765 (Fcopy_sequence): Don't assume vector length fits in int.
16767 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16768 (header_size, word_size): New constants.
16769 (allocate_vectorlike): Don't check size overflow here.
16770 (allocate_vector): Check it here instead, since this is the only
16771 caller of allocate_vectorlike that could cause overflow.
16772 Check that the new vector's length is representable as a fixnum.
16774 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16775 The previous code was bogus. For example, next_almost_prime (32)
16776 returned 39, which is undesirable as it is a multiple of 3; and
16777 next_almost_prime (24) returned 25, which is a multiple of 5 so
16778 why was the code bothering to check for multiples of 7?
16780 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16782 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16784 Variadic C functions now count arguments with ptrdiff_t.
16785 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16786 Back then I didn't know that the Emacs coding style prefers signed int.
16787 Also, in the meantime I found a few more instances where arguments
16788 were being counted with int, which may truncate counts on 64-bit
16789 machines, or EMACS_INT, which may be unnecessarily wide.
16790 * lisp.h (struct Lisp_Subr.function.aMANY)
16791 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16792 Arg counts are now ptrdiff_t, not size_t.
16793 All variadic functions and their callers changed accordingly.
16794 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16795 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16796 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16797 * callint.c (Fcall_interactively): Check arg count for overflow,
16798 to avoid potential buffer overrun. Use signed char, not 'int',
16799 for 'varies' array, so that we needn't bother to check its size
16800 calculation for overflow.
16801 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16802 * eval.c (apply_lambda):
16803 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16804 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16805 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16807 * callint.c (Fcall_interactively): Don't use index var as event count.
16809 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16810 * mem-limits.h (SIZE): Remove; no longer used.
16812 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16814 Remove unnecessary casts.
16815 * xterm.c (x_term_init):
16816 * xfns.c (x_set_border_pixel):
16817 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16818 These aren't needed now that we assume ANSI C.
16820 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16821 It's more likely to cause problems (due to unsigned overflow)
16824 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16826 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16828 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16830 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16832 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16834 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16836 GLYPH_CODE_FACE returns EMACS_INT, not int.
16837 * dispextern.h (merge_faces):
16838 * xfaces.c (merge_faces):
16839 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16840 Don't assume EMACS_INT fits in int.
16842 * character.h (CHAR_VALID_P): Remove unused parameter.
16843 * fontset.c, lisp.h, xdisp.c: All uses changed.
16845 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16847 * fns.c (concat): Minor tuning based on overflow analysis.
16848 This doesn't fix any bugs. Use int to hold character, instead
16849 of constantly refetching from Emacs object. Use XFASTINT, not
16850 XINT, for value known to be a character. Don't bother comparing
16851 a single byte to 0400, as it's always less.
16853 * floatfns.c (Fexpt):
16854 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16856 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16859 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16861 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16862 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16863 incorrectly succeed when S was a string, because 4294967386 was
16864 truncated before it was used.
16866 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16867 Otherwise, an out-of-range integer could cause undefined behavior
16870 * composite.c: Use int, not EMACS_INT, for characters.
16871 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16872 EMACS_INT, for values that are known to be in character range.
16873 This doesn't fix any bugs but is the usual style inside Emacs and
16874 may generate better code on 32-bit machines.
16876 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16877 This is for reasons similar to the recent CHAR_STRING fix.
16878 * charset.c (Fencode_char): Check that character arg is actually
16879 a character. Pass an int to ENCODE_CHAR.
16880 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16881 wider than 'int', as a compile-time check to prevent future regressions
16884 * character.c (char_string): Remove unnecessary casts.
16886 Make sure a 64-bit char is never passed to CHAR_STRING.
16887 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16888 by silently ignoring the top 32 bits, allowing some values
16889 that were far too large to be valid characters.
16890 * character.h: Include <verify.h>.
16891 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16892 arguments are no wider than unsigned, as a compile-time check
16893 to prevent future regressions in this area.
16895 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16896 (Fsubst_char_in_region):
16898 * xdisp.c (decode_mode_spec_coding):
16899 Adjust to CHAR_STRING's new requirement.
16900 * editfns.c (Finsert_char, Fsubst_char_in_region):
16901 * fns.c (concat): Check that character args are actually
16902 characters. Without this test, these functions did the wrong
16903 thing with wildly out-of-range values on 64-bit hosts.
16905 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16906 These casts should not be needed on 32-bit hosts, either.
16907 * keyboard.c (read_char):
16908 * lread.c (Fload): Remove casts to unsigned.
16910 * lisp.h (UNSIGNED_CMP): New macro.
16911 This fixes comparison bugs on 64-bit hosts.
16912 (ASCII_CHAR_P): Use it.
16913 * casefiddle.c (casify_object):
16914 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16915 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16916 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16917 * dispextern.h (FACE_FROM_ID):
16918 * keyboard.c (read_char): Use UNSIGNED_CMP.
16920 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16921 not to EMACS_INT, to avoid GCC warning.
16923 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16925 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16926 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16927 isn't needed on 32-bit machines.
16929 * buffer.c (Fgenerate_new_buffer_name):
16930 Use EMACS_INT for count, not int.
16931 (advance_to_char_boundary): Return EMACS_INT, not int.
16933 * data.c (Qcompiled_function): Now static.
16935 * window.c (window_body_lines): Now static.
16937 * image.c (gif_load): Rename local to avoid shadowing.
16939 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16940 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16941 * alloc.c (make_save_value): Integer argument is now of type
16942 ptrdiff_t, not int.
16943 (mark_object): Use ptrdiff_t, not int.
16944 * lisp.h (pD): New macro.
16945 * print.c (print_object): Use it.
16947 * alloc.c: Use EMACS_INT, not int, to count objects.
16948 (total_conses, total_markers, total_symbols, total_vector_size)

16958 These were 'int' variables that could overflow on 64-bit hosts;
16959 they were never used, so remove them instead of repairing them.

16976 The definition here is exact; the one in lisp.h was approximate.
16977 (allocate_string_data): Check for string overflow. This catches
16978 some instances we weren't catching before. Also, it catches
16979 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16980 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16981 and ptrdiff_t and EMACS_INT are both 64 bits.

17489 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
17490 Do not assume that spare memory exists; that assumption is valid
17491 only if SYSTEM_MALLOC.
17492 (LARGE_REQUEST): New macro, so that the issue of large requests
17493 is separated from the issue of spare memory.

17562 instead of using explicit *_CHAR codes.
17563 (bidi_resolve_explicit, bidi_resolve_weak):

17572 (bidi_level_of_next_char): Don't try to lookup the cache for the
17573 next/previous character if nothing is cached there yet, or if we
17574 were just reseat()'ed to a new position.
17576 * xdisp.c (set_cursor_from_row): Set start and stop points
17577 according to the row's direction when priming the loop that looks
17578 for the glyph on which to display cursor.
17579 (single_display_spec_intangible_p): Function deleted.
17580 (display_prop_intangible_p): Reimplement to call
17581 handle_display_spec instead of single_display_spec_intangible_p.
17582 Accept 3 additional arguments needed by handle_display_spec.
17583 This fixes incorrect cursor motion across display property with complex
17584 values: lists, `(when COND...)' forms, etc.

17586 lists with the argument STRING its top-level element.
17587 (display_prop_string_p): Fix the condition for processing a

17590 last portion of handle_display_prop.
17591 (compute_display_string_pos): Accept additional argument
17592 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17593 value of a `display' property is a "replacing spec".
17594 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17595 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17596 the display property, but just return a value indicating whether
17597 the display property will replace the characters it covers.
17598 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17599 frame_window_p members of struct bidi_it.
17600 (compute_display_string_pos, compute_display_string_end):

17623 All callers changed. (Bug#8762)
17625 * gnutls.c: Use Emacs's memory allocators.
17626 Without this change, the gnutls library would invoke malloc etc.
17627 directly, which causes problems on non-SYNC_INPUT hosts, and which
17628 runs afoul of improving memory_full behavior. (Bug#8761)
17629 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17630 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17631 xfree instead of the default malloc, realloc, free.
17632 (Fgnutls_boot): No need to check for memory allocation failure,
17633 since xmalloc does that for us.
17635 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

17655 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17656 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17657 * alloc.c (allocate_vectorlike):
17658 Check for overflow in vector size calculations.
17659 * ccl.c (ccl_driver):
17660 Check for overflow when converting EMACS_INT to int.

17662 need to be updated by these changes.
17663 * fns.c (make_hash_table, maybe_resize_hash_table):
17664 Check for integer overflow with large hash tables.
17665 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17666 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17667 (SXHASH_REDUCE): New macro.
17668 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17669 Use it instead of discarding useful hash info with large hash values.
17670 (sxhash_float): New function.
17671 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17672 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17673 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17674 Rewrite to use FIXNUM_BITS, as this simplifies things.
17675 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17676 Adjust signatures to match updated version of code.
17677 (consing_since_gc): Now EMACS_INT, since a single hash table can
17678 use more than INT_MAX bytes.

17727 Make it possible to run ./temacs.
17729 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17730 syms_of_callproc does the same thing. Remove test for

17791 * fns.c (to_uchar): Define.
17792 (crypto_hash_function): Use it to convert some newly-signed
17793 variables to unsigned, to avoid sign-extension bugs. For example,
17794 without this change, (md5 "truc") would evaluate to
17795 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17796 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in

17812 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17813 Use XFASTINT rather than XUINT when numbers are nonnegative.
17814 (xd_append_arg, Fdbus_method_return_internal):
17815 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17816 arguments, check that Lisp number is nonnegative, rather than
17817 silently wrapping negative numbers around. (Bug#8722)
17818 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17821 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17823 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17825 ccl: Add integer overflow checks.
17826 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17827 (IN_INT_RANGE): New macros.
17828 (ccl_driver): Use them to check for integer overflow when
17829 decoding a CCL program. Many of the new checks are whether XINT (x)
17830 fits in int; it doesn't always, on 64-bit hosts. The new version
17831 doesn't catch all possible integer overflows, but it's an
17832 improvement. (Bug#8719)
17834 * alloc.c (make_event_array): Use XINT, not XUINT.
17835 There's no need for unsigned here.
17837 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17838 This follows up to the 2011-05-06 change that substituted uintptr_t
17839 for EMACS_INT. This case wasn't caught back then.
17841 Rework Fformat to avoid integer overflow issues.
17842 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17843 now (part of C89). Include <verify.h>.
17844 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17845 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17846 (Fformat): Avoid the prepass trying to compute sizes; it was only
17847 approximate and thus did not catch overflow reliably. Instead, walk
17848 through the format just once, formatting and computing sizes as we go,
17849 checking for integer overflow at every step, and allocating a larger
17850 buffer as needed. Keep track separately whether the format is
17851 multibyte. Keep only the most-recently calculated precision, rather
17852 than them all. Record whether each argument has been converted to
17853 string. Use EMACS_INT, not int, for byte and char and arg counts.
17854 Support field widths and precisions larger than INT_MAX. Avoid
17855 sprintf's undefined behavior with conversion specifications such as %#d
17856 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17857 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17858 formatting out-of-range floating point numbers with int
17859 formats. (Bug#8668)
17861 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17863 * data.c: Avoid integer truncation in expressions involving floats.
17864 * data.c: Include <intprops.h>.
17865 (arith_driver): When there's an integer overflow in an expression
17866 involving floating point, convert the integers to floating point
17867 so that the resulting value does not suffer from catastrophic
17868 integer truncation. For example, on a 64-bit host (* 4
17869 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17870 Do not rely on undefined behavior after integer overflow.
17872 merge count_size_as_multibyte, parse_str_to_multibyte
17873 * character.c, character.h (count_size_as_multibyte):
17874 Rename from parse_str_to_multibyte; all uses changed.
17875 Check for integer overflow.
17876 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17877 since it's now a duplicate of the other. This is more of
17878 a character than a buffer op, so better that it's in character.c.
17879 * fns.c, print.c: Adjust to above changes.
17881 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17883 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17885 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17887 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17888 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17889 (x_clipboard_manager_save): Now static.
17890 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17892 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17893 (crypto_hash_function): Now static.
17894 Fix pointer signedness problems. Avoid unnecessary initializations.
17896 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17898 * termhooks.h (Vselection_alist): Make it terminal-local.
17900 * terminal.c (create_terminal): Initialize it.
17902 * xselect.c: Support for clipboard managers.
17903 (Vselection_alist): Move to termhooks.h as terminal-local var.
17904 (LOCAL_SELECTION): New macro.
17905 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17906 (symbol_to_x_atom): Remove gratuitous arg.
17907 (x_handle_selection_request, lisp_data_to_selection_data)
17908 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17909 (x_own_selection, x_get_local_selection, x_convert_selection):
17910 New arg, specifying work frame. Use terminal-local Vselection_alist.
17911 (some_frame_on_display): Delete unused function.
17912 (Fx_own_selection_internal, Fx_get_selection_internal)
17913 (Fx_disown_selection_internal, Fx_selection_owner_p)
17914 (Fx_selection_exists_p): New optional frame arg.
17915 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17916 (x_handle_selection_clear): Don't treat other terminals with the
17917 same keyboard specially. Use the terminal-local Vselection_alist.
17918 (x_clear_frame_selections): Use Frun_hook_with_args.
17920 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17922 * xterm.h: Add support for those atoms.
17924 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17926 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17927 (converted_selections, conversion_fail_tag): New global variables.
17928 (x_selection_request_lisp_error): Free the above.
17929 (x_get_local_selection): Remove unnecessary code.
17930 (x_reply_selection_request): Args changed; handle arbitrary array
17931 of converted selections stored in converted_selections.
17932 Separate the XChangeProperty and SelectionNotify steps.
17933 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17934 (x_convert_selection): New function.
17935 (x_handle_selection_event): Simplify.
17936 (x_get_foreign_selection): Don't ignore incoming requests while
17937 waiting for an answer; this will fail when we implement
17938 SAVE_TARGETS, and seems unnecessary anyway.
17939 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17940 (Vx_sent_selection_functions): Doc fix.
17942 2011-05-26 Leo Liu <sdl.web@gmail.com>
17944 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17946 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17948 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17950 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17951 for fringe update if it has periodic bitmap.
17952 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17953 and fringe_bitmap_periodic_p.
17955 * fringe.c (get_fringe_bitmap_data): New function.
17956 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17957 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17958 row. Mark glyph row for fringe update if periodicity changed.
17960 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17961 for fringe update unless it has periodic bitmap.
17963 2011-05-25 Kenichi Handa <handa@m17n.org>
17965 * xdisp.c (get_next_display_element): Set correct it->face_id for
17966 a static composition.
17968 2011-05-24 Leo Liu <sdl.web@gmail.com>
17971 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17973 * fns.c (crypto_hash_function, Fsha1): New function.
17974 (Fmd5): Use crypto_hash_function.
17975 (syms_of_fns): Add Ssha1.
17977 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17979 * gnutls.c: Remove unused macros.
17980 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17981 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17982 Remove macros that are defined and never used.
17983 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17985 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17987 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17988 (Fx_get_selection_internal): Minor cleanup.
17989 (Fx_own_selection_internal): Rename arguments for consistency with
17992 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17994 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17996 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17998 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18000 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18002 * dispnew.c (scrolling_window): Don't exclude the case that the
18003 last enabled row in the desired matrix touches the bottom boundary.
18005 2011-05-21 Glenn Morris <rgm@gnu.org>
18007 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18008 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18009 and add some more files.
18011 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18013 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18014 report_file_error introduced by the change from 2011-05-07.
18016 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18018 * systime.h (Time): Define only if emacs is defined.
18019 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18020 where the include path doesn't have X11/X.h by default. See
18021 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18023 2011-05-20 Kenichi Handa <handa@m17n.org>
18025 * composite.c (find_automatic_composition): Fix previous change.
18027 2011-05-20 Glenn Morris <rgm@gnu.org>
18029 * lisp.mk: New file, split from Makefile.in.
18030 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18031 (shortlisp): Remove.
18032 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18034 2011-05-19 Glenn Morris <rgm@gnu.org>
18036 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18037 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18038 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18039 (lisp): Set the order to that of loadup.el.
18040 (shortlisp): Make it a copy of $lisp.
18041 (SOME_MACHINE_LISP): Remove.
18042 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18043 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18045 2011-05-18 Kenichi Handa <handa@m17n.org>
18047 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18048 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18049 (find_automatic_composition): Mostly rewrite for efficiency.
18051 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18053 * makefile.w32-in: Update dependencies.
18055 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18057 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18058 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18060 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18062 Fix some integer overflow issues, such as string length overflow.
18064 * insdel.c (count_size_as_multibyte): Check for string overflow.
18066 * character.c (lisp_string_width): Check for string overflow.
18067 Use EMACS_INT, not int, for string indexes and lengths; in
18068 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18069 the resulting string length overflows an EMACS_INT; instead,
18070 report a string overflow if no precision given. When checking for
18071 precision exhaustion, use a check that cannot possibly have
18072 integer overflow. (Bug#8675)
18073 * character.h (lisp_string_width): Adjust to new signature.
18075 * alloc.c (string_overflow): New function.
18076 (Fmake_string): Use it. This doesn't change behavior, but saves
18077 a few bytes and will simplify future changes.
18078 * character.c (string_escape_byte8): Likewise.
18079 * lisp.h (string_overflow): New decl.
18081 Fixups, following up to the user-interface timestamp change.
18082 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18083 for UI timestamps, instead of unsigned long.
18084 * msdos.c (mouse_get_pos): Likewise.
18085 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18086 * w32gui.h (Time): Define by including "systime.h" rather than by
18087 declaring it ourselves. (Bug#8664)
18089 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18090 * image.c (clear_image_cache): Likewise.
18092 * term.c (term_mouse_position): Don't assume time_t wraparound.
18094 Be more systematic about user-interface timestamps.
18095 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18096 and sometimes 'EMACS_UINT', to represent these timestamps.
18097 This change causes it to use 'Time' uniformly, as that's what X uses.
18098 This makes the code easier to follow, and makes it easier to catch
18099 integer overflow bugs such as Bug#8664.
18100 * frame.c (Fmouse_position, Fmouse_pixel_position):
18101 Use Time, not unsigned long, for user-interface timestamps.
18102 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18103 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18104 * keyboard.h (last_event_timestamp): Likewise.
18105 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18106 * menu.h (xmenu_show): Likewise.
18107 * term.c (term_mouse_position): Likewise.
18108 * termhooks.h (struct input_event.timestamp): Likewise.
18109 (struct terminal.mouse_position_hook): Likewise.
18110 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18111 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18112 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18113 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18114 what it was before.
18115 * menu.h, termhooks.h: Include "systime.h", for Time.
18117 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18118 Don't assume that the difference between two unsigned long values
18119 can fit into an integer. At this point, we know button_down_time
18120 <= event->timestamp, so the difference must be nonnegative, so
18121 there's no need to cast the result if double-click-time is
18122 nonnegative, as it should be; check that it's nonnegative, just in
18123 case. This bug is triggered when events are more than 2**31 ms
18124 apart (about 25 days). (Bug#8664)
18126 * xselect.c (last_event_timestamp): Remove duplicate decl.
18127 (x_own_selection): Remove needless cast to unsigned long.
18129 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18130 that always fit in int. Use a sentinel instead of a counter, to
18131 avoid a temp and to allay GCC's concerns about possible int overflow.
18132 * frame.h (struct frame): Use int for menu_bar_items_used
18133 instead of EMACS_INT, since it always fits in int.
18135 * menu.c (grow_menu_items): Check for int overflow.
18137 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18139 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18140 Before, the code was not consistent. These values cannot exceed
18141 2**31 - 1 so there's no need to make them unsigned.
18142 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18143 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18144 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18146 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18148 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18149 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18150 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18151 presumably because the widths might not match.
18153 * window.c (size_window): Avoid needless test at loop start.
18155 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18157 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18159 2011-05-12 Drew Adams <drew.adams@oracle.com>
18161 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18163 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18165 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18166 `width' to `bar_area_x' and `bar_area_width', respectively.
18167 (x_scroll_run): Take account of fringe background extension.
18169 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18170 Rename local vars `left' and `width' to `bar_area_x' and
18171 `bar_area_width', respectively.
18172 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18173 background extension.
18175 2011-05-10 Jim Meyering <meyering@redhat.com>
18177 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18179 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18181 * image.c (Finit_image_library): Return t for built-in image types,
18182 like pbm and xbm. (Bug#8640)
18184 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18186 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18188 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18190 * w32console.c (Fset_screen_color): Doc fix.
18191 (Fget_screen_color): New function.
18192 (syms_of_ntterm): Defsubr it.
18194 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18195 unlink the temporary file if Fcall_process didn't create it in the
18197 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18198 child process will be redirected to a file specified with `:file'.
18199 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18200 cue to call_process_cleanup not to close that handle.
18202 2011-05-07 Ben Key <bkey76@gmail.com>
18204 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18205 one of two shell specific rules, either bootstrap-temacs-CMD or
18206 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18207 to the previous implementation of the bootstrap-temacs rule.
18208 The bootstrap-temacs-CMD rule is similar to the previous
18209 implementation of the bootstrap-temacs rule except that it
18210 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18213 These changes, along with some changes to nt/configure.bat,
18214 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18215 earlier fix to add support for --cflags and --ldflags options
18216 that include quotes so that it works whether make uses cmd or
18219 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18221 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18222 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18224 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18225 a string. Handle both cases.
18226 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18227 (Fdbus_register_method): Use Qinvalid_function.
18229 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18231 * makefile.w32-in: Update dependencies.
18232 (LISP_H): Add inttypes.h and stdin.h.
18233 (PROCESS_H): Add unistd.h.
18235 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18237 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18238 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18240 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18242 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18244 * term.c (vfatal): Remove stray call to va_end.
18245 It's not needed and the C Standard doesn't allow it here anyway.
18247 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18248 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18250 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18253 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18255 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18257 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18259 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18261 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18263 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18264 * charset.c (Fdefine_charset_internal): Don't initialize
18265 charset.code_space[15]. The value was garbage, on hosts with
18266 32-bit int (Bug#8600).
18268 * lread.c (read_integer): Be more consistent with string-to-number.
18269 Use string_to_number to do the actual conversion; this avoids
18270 rounding errors and fixes some other screwups. Without this fix,
18271 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18272 (digit_to_number): Move earlier, for benefit of read_integer.
18273 Return -1 if the digit is out of range for the base, -2 if it is
18274 not a digit in any supported base. (Bug#8602)
18276 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18278 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18279 to match comment at start of function. This also removes a
18280 GCC warning about overflow in a 32+64-bit port.
18282 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18284 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18285 Reported by Stefan Monnier in
18286 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18287 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18288 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18290 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18291 (EMACS_UINTPTR): Likewise, with uintptr_t.
18293 * lisp.h: Prefer 64-bit EMACS_INT if available.
18294 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18295 on 32-bit hosts that have 64-bit int, so that they can access
18297 However, temporarily disable this change unless the temporary
18298 symbol WIDE_EMACS_INT is defined.
18300 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18302 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18303 This removes an assumption that EMACS_INT and long are the same
18304 width as pointers. The assumption is true for Emacs porting targets
18305 now, but we want to make other targets possible.
18306 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18307 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18308 In the rest of the code, change types of integers that hold casted
18309 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18310 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18311 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18312 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18313 No need to cast type when ORing.
18314 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18315 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18316 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18317 assume EMACS_INT is the same width as char *.
18318 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18319 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18320 Remove no-longer-needed casts.
18321 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18322 (xg_tool_bar_help_callback, xg_make_tool_item):
18323 Use EMACS_INTPTR to hold an integer
18324 that will be cast to void *; this can avoid a GCC warning
18325 if EMACS_INT is not the same width as void *.
18326 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18327 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18328 (current_message_1, set_message_1):
18329 Use a local to convert to proper width without a cast.
18330 * xmenu.c (dialog_selection_callback): Likewise.
18332 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18333 Also, don't assume VALBITS / RAND_BITS is less than 5,
18334 and don't rely on undefined behavior when shifting a 1 left into
18336 * lisp.h (get_random): Change signature to match.
18338 * lread.c (hash_string): Use size_t, not int, for hash computation.
18339 Normally we prefer signed values; but hashing is special, because
18340 it's better to use unsigned division on hash table sizes so that
18341 the remainder is nonnegative. Also, size_t is the natural width
18342 for hashing into memory. The previous code used 'int', which doesn't
18343 retain enough info to hash well into very large tables.
18344 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18346 * dbusbind.c: Don't possibly lose pointer info when converting.
18347 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18348 Use XPNTR rather than XHASH, so that the high-order bits of
18349 the pointer aren't lost when converting through void *.
18351 * eval.c (Fautoload): Don't double-shift a pointer.
18353 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18355 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18357 * gnutls.c (DEF_GNUTLS_FN):
18358 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18360 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18362 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18365 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18367 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18368 New version that can reserve upto 2GB of heap space.
18370 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18372 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18374 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18376 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18377 `gnutls_certificate_set_x509_key_file'.
18379 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18381 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18382 Update dependencies.
18384 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18386 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18387 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18388 Remove unused parameter `fildes'.
18389 * process.c (read_process_output, send_process): Don't pass it.
18391 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18393 Fix previous change: the library cache is defined in w32.c.
18394 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18395 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18397 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18399 Implement dynamic loading of GnuTLS on Windows.
18401 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18402 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18403 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18406 * gnutls.c (Qgnutls_dll): Define.
18407 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18408 (gnutls_*): Declare function pointers.
18409 (init_gnutls_functions): New function to initialize function pointers.

18412 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18413 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18414 (emacs_gnutls_write, emacs_gnutls_read)
18415 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18416 (Fgnutls_available_p): New function.
18417 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

18425 (w32_delayed_load): Move to w32.c.
18427 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18429 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18430 (w32_delayed_load): Move from image.c. When loading a library, record
18431 its filename in the :loaded-from property of the library id.
18432 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18433 Initialize and staticpro them.
18434 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18436 * process.c: Include lisp.h before w32.h, not after.
18437 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18438 instead of gnutls_record_check_pending.
18440 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18442 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18444 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18445 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18448 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18450 * xterm.c (x_set_frame_alpha): Do not set property on anything
18451 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18453 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18455 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18457 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18459 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

18473 * sysdep.c (wait_for_termination_1): Make static.
18474 (wait_for_termination, interruptible_wait_for_termination):
18475 Move after wait_for_termination_1.
18477 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18479 * sysdep.c (interruptible_wait_for_termination): New function
18480 which is like wait_for_termination, but allows keyboard
18483 * callproc.c (Fcall_process): Add (:file "file") as an option for
18485 (Fcall_process_region): Ditto.
18487 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18489 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18490 rather than `XVECTOR (FOO)->size'.
18492 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18493 inttypes.h, as a gnulib replacement is used if it not available in
18496 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18498 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18499 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18500 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18502 * coding.c (coding_alloc_by_realloc): Error out if destination
18503 will grow beyond MOST_POSITIVE_FIXNUM.
18504 (decode_coding_emacs_mule): Abort if there isn't enough place in
18505 charbuf for the composition carryover bytes. Reserve an extra
18506 space for up to 2 characters produced in a loop.
18507 (decode_coding_iso_2022): Abort if there isn't enough place in
18508 charbuf for the composition carryover bytes.
18510 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18512 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18513 aborting when %lld or %lll format is passed.
18514 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18515 %llo or %llx format is passed. (Bug#8545)
18517 * window.c (window_scroll_line_based): Use a marker instead of
18518 simple variables to record original value of point. (Bug#7952)
18520 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18521 produced by %s or %c overflows available buffer space. (Bug#8545)
18523 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18525 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18526 (SIZE_MAX): Move defn after all includes, as they might #define it.
18528 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

18532 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18534 * keyboard.c (Qdelayed_warnings_hook): Define.
18535 (command_loop_1): Run `delayed-warnings-hook'
18536 if Vdelayed_warnings_list is non-nil.
18537 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18538 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18540 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18542 * doprnt.c (doprnt): Don't return value smaller than the buffer
18543 size if the message was truncated. (Bug#8545).
18545 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18547 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18548 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18550 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18552 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18554 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18556 * makefile.w32-in: Update dependencies.
18558 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18560 Improve `doprnt' and its usage. (Bug#8545)
18561 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18562 `format_end'. Remove support for %l as a conversion specifier.
18563 Don't use xrealloc. Improve diagnostics when the %l size modifier
18564 is used. Update the commentary.
18566 * eval.c (verror): Simplify calculation of size_t.
18568 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18571 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18573 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18576 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18578 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18579 This makes this file independent of the recent pseudovector change.
18581 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18583 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18585 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18586 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18587 Remove unused local.
18588 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18590 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18591 GCC 4.6.0 optimizes based on type-based alias analysis.
18592 For example, if b is of type struct buffer * and v of type struct
18593 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18594 != &v->size, and therefore "v->size = 1; b->size = 2; return
18595 v->size;" must therefore return 1. This assumption is incorrect
18596 for Emacs, since it type-puns struct Lisp_Vector * with many other
18597 types. To fix this problem, this patch adds a new type struct
18598 vectorlike_header that documents the constraints on layout of vectors
18599 and pseudovectors, and helps optimizing compilers not get fooled
18600 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18601 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18602 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18604 (XSETPVECTYPE): Rewrite in terms of new macro.
18605 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18606 This is a bit clearer, and further avoids the possibility of
18607 undesirable aliasing.
18608 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18609 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18610 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18611 since Lisp_Subr is a special case (no "next" field).
18612 (ASIZE): Now uses header.size rather than size.
18613 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18614 to avoid the hassle of writing XVECTOR (foo)->header.size.
18615 (struct vectorlike_header): New type.
18616 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18617 object, to help avoid aliasing.
18618 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18619 (SUBRP): Likewise, since Lisp_Subr is a special case.
18620 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18621 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18622 (struct Lisp_Hash_Table): Combine first two members into a single
18623 struct vectorlike_header member. All uses of "size" and "next" members
18624 changed to be "header.size" and "header.next".
18625 * buffer.h (struct buffer): Likewise.
18626 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18627 * frame.h (struct frame): Likewise.
18628 * process.h (struct Lisp_Process): Likewise.
18629 * termhooks.h (struct terminal): Likewise.
18630 * window.c (struct save_window_data, struct saved_window): Likewise.
18631 * window.h (struct window): Likewise.
18632 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18633 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18634 * buffer.c (init_buffer_once): Likewise.
18635 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18637 * process.c (Fformat_network_address): Use local var for size,
18640 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18642 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18643 * data.c (atof): Remove decl; no longer used or needed.
18644 (digit_to_number): Move to lread.c.
18645 (Fstring_to_number): Use new string_to_number function, to be
18646 consistent with how the Lisp reader treats infinities and NaNs.
18647 Do not assume that floating-point numbers represent EMACS_INT
18648 without losing information; this is not true on most 64-bit hosts.
18649 Avoid double-rounding errors, by insisting on integers when
18650 parsing non-base-10 numbers, as the documentation specifies.
18651 * lisp.h (string_to_number): New decl, replacing ...
18652 (isfloat_string): Remove.
18653 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18654 (read1): Do not accept +. and -. as integers; this
18655 appears to have been a coding error. Similarly, do not accept
18656 strings like +-1e0 as floating point numbers. Do not report
18657 overflow for integer overflows unless the base is not 10 which
18658 means we have no simple and reliable way to continue.
18659 Break out the floating-point parsing into a new
18660 function string_to_number, so that Fstring_to_number parses
18661 floating point numbers consistently with the Lisp reader.
18662 (digit_to_number): Move here from data.c. Make it static inline.
18663 (E_CHAR, EXP_INT): Remove, replacing with ...
18664 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18665 (string_to_number): New function, replacing isfloat_string.
18666 This function checks for valid syntax and produces the resulting
18667 Lisp float number too. Rework it so that string-to-number
18668 no longer mishandles examples like "1.0e+". Use strtoumax,
18669 so that overflow for non-base-10 numbers is reported only when
18670 there's no portable and simple way to convert to floating point.
18672 * textprop.c (set_text_properties_1): Rewrite for clarity,
18673 and to avoid GCC warning about integer overflow.
18675 * intervals.h (struct interval): Use EMACS_INT for members
18676 where EMACS_UINT might cause problems. See
18677 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18678 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18679 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18681 (offset_intervals): Tell GCC not to worry about length overflow
18682 when negating a negative length.
18684 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18685 (overrun_check_free): Likewise.
18687 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18688 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18691 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18692 (gnutls_make_error): Rename local to avoid shadowing.

18695 Comment out unused local. Fix pointer signedness problems.
18697 * lread.c (openp): Don't stuff size_t into an 'int'.
18698 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18699 about possible signed overflow.
18701 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18702 (GDK_KEY_g): Don't define if already defined.
18703 (xg_prepare_tooltip): Avoid pointer signedness problem.
18704 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18706 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18707 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18709 * xfns.c (Fx_window_property): Simplify a bit,
18710 to make a bit faster and to avoid GCC 4.6.0 warning.
18711 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18713 * fns.c (internal_equal): Don't assume size_t fits in int.
18715 * alloc.c (compact_small_strings): Tighten assertion a little.
18717 Replace pEd with more-general pI, and fix some printf arg casts.
18718 * lisp.h (pI): New macro, generalizing old pEd macro to other
18719 conversion specifiers. For example, use "...%"pI"d..." rather
18720 than "...%"pEd"...".
18721 (pEd): Remove. All uses replaced with similar uses of pI.
18722 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18723 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18724 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18725 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.

18727 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18728 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18730 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18731 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18732 * print.c (safe_debug_print, print_object): Likewise.
18733 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18735 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18736 avoiding the 0 flag, which is not portable.
18737 * process.c (Fmake_network_process): Use pI to avoid cast.
18738 * region-cache.c (pp_cache): Likewise.
18739 * xdisp.c (decode_mode_spec): Likewise.
18740 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18741 behavior on 64-bit hosts with printf arg.
18742 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18743 (x_stop_queuing_selection_requests): Likewise.
18744 (x_get_window_property): Don't truncate byte count to an 'int'
18747 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18748 here, since it parses constructs like leading '-' and spaces,
18749 which are not wanted; and it overflows with large numbers.
18750 Instead, simply match F[0-9]+, which is what is wanted anyway.
18752 * alloc.c: Remove unportable assumptions about struct layout.
18753 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18754 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18755 (allocate_vectorlike, make_pure_vector): Use the new macros,
18756 plus offsetof, to remove unportable assumptions about struct layout.
18757 These assumptions hold on all porting targets that I know of, but
18758 they are not guaranteed, they're easy to remove, and removing them
18759 makes further changes easier.
18761 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18762 This doesn't fix a bug but makes the code clearer.
18763 (string_overrun_cookie): Now const. Use initializers that
18764 don't formally overflow signed char, to avoid warnings.
18765 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18766 can cause Emacs to crash when string overrun checking is enabled.
18767 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18768 multiple of sizeof (EMACS_INT); it need not be, if
18769 alignof(EMACS_INT) < sizeof (EMACS_INT).
18770 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18772 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18799 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18801 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18802 "cast to pointer from integer of different size".
18804 Improve doprnt and its use in verror. (Bug#8545)
18805 * doprnt.c (doprnt): Document the set of format control sequences
18806 supported by the function. Use SAFE_ALLOCA instead of always
18809 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18810 is one byte too soon. Don't use xrealloc; instead xfree and
18813 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18815 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

18819 gnutls_global_initialized. Added internals for the
18820 :verify-hostname-error, :verify-error, and :verify-flags
18821 parameters of `gnutls-boot' and documented those parameters in the
18822 docstring. Start callback support.
18823 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18824 unless a fatal error occurred. Call gnutls_alert_send_appropriate

18902 conversions. Support %l conversion. Don't assume an EMACS_INT
18903 argument for integer conversions and for %c.

18922 * callint.c (Fcall_interactively): When displaying error message
18923 about invalid control letter, pass the character's codepoint, not

18928 codepoint of an invalid character, to avoid displaying a bogus
18931 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18932 `error', not SYMBOL_NAME itself.

18937 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18938 to `error' in error message about FINAL_CHAR argument. Make sure
18939 FINAL_CHAR is a character, and use %c when it is passed as
18940 argument to `error'.
18942 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18944 * s/ms-w32.h (localtime): Redirect to sys_localtime.
18946 * w32.c: Include <time.h>.

19007 by pacifying GCC about it. Maybe it's time to retire it?
19008 * xfaces.c (USG, __TIMEVAL__): Likewise.
19010 * dispextern.h (struct redisplay_interface): Rename param
19011 to avoid shadowing.
19012 * termhooks.h (struct terminal): Likewise.
19013 * xterm.c (xembed_send_message): Likewise.
19015 * insdel.c (make_gap_smaller): Define only if
19016 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.

19059 compatible char. Avoid the old compiler warnings about
19060 out-of-range initializers by using, for example, '\xab' rather
19063 * xgselect.c (xgselect_initialize): Check vs interface
19064 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

19114 (group_in_compile_stack, re_search, re_search_2, regex_compile)
19115 (re_compile_pattern, re_exec): Declare arguments and local
19116 variables `size_t' and `ssize_t' and return values `regoff_t', as

19124 specify buffer/string position and length are now ssize_t and
19125 size_t. Return type is regoff_t.
19127 2011-04-16 Ben Key <bkey76@gmail.com>
19129 * nsfont.m: Fixed bugs in ns_get_family and
19130 ns_descriptor_to_entity that were caused by using free to
19131 deallocate memory blocks that were allocated by xmalloc (via
19132 xstrdup). This caused Emacs to crash when compiled with
19133 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19134 --enable-checking=xmallocoverrun). xfree is now used to
19135 deallocate these memory blocks.

19562 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19563 Mark functions with DEFUE instead of DEFUN,
19564 if they are used in other modules.
19565 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19566 decls for now-static functions.
19567 * buffer.h (Fdelete_overlay): Remove decl.
19568 * callproc.c (Fgetenv_internal): Mark as internal.

19576 * fileio.c (Fmake_symbolic_link): New forward static decl.
19577 * image.c (Finit_image_library): New forward static decl.

19603 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19605 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19606 when at ZV. (Bug#8487)
19608 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19610 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19612 * keyboard.c (parse_tool_bar_item): Likewise.
19613 * sound.c (sound_cleanup, alsa_close): Likewise.
19614 * termcap.c (tgetent): Likewise.
19615 * xfns.c (x_default_font_parameter): Likewise.
19616 * xsettings.c (read_and_apply_settings): Likewise.
19618 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19619 (overrun_check_free): Protoize.
19621 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19623 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19624 since callers should never pass a negative size.
19625 Change the signature to match that of plain 'read' and 'write'; see
19626 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19627 * lisp.h: Update prototypes of emacs_write and emacs_read.
19629 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19631 * xdisp.c (redisplay_window): Don't try to determine the character
19632 position of the scroll margin if the window start point w->startp
19633 is outside the buffer's accessible region. (Bug#8468)
19635 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19637 Fix write-region and its subroutines for buffers > 2GB.
19638 * fileio.c (a_write, e_write): Modify declaration of arguments and
19639 local variables to support buffers larger than 2GB.
19640 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19642 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19643 argument, local variables, and return value.
19645 * lisp.h: Update prototypes of emacs_write and emacs_read.
19647 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19649 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19651 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19653 Fix more problems found by GCC 4.6.0's static checks.
19655 * xdisp.c (vmessage): Use a better test for character truncation.
19657 * charset.c (load_charset_map): <, not <=, for optimization,
19658 and to avoid potential problems with integer overflow.
19659 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19660 * casetab.c (set_identity, shuffle): Likewise.
19661 * editfns.c (Fformat): Likewise.
19662 * syntax.c (skip_chars): Likewise.
19664 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19665 This also lets GCC 4.6.0 generate slightly better loop code.
19667 * callint.c (Fcall_interactively): <, not <=, for optimization.
19668 (Fcall_interactively): Count the number of arguments produced,
19669 not the number of arguments given. This is simpler and lets GCC
19670 4.6.0 generate slightly better code.
19672 * ftfont.c: Distingish more carefully between FcChar8 and char.
19673 The previous code passed unsigned char * to a functions like
19674 strlen and xstrcasecmp that expect char *, which does not
19675 conform to the C standard.
19676 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19677 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19678 char * when the C standard requires it.
19680 * keyboard.c (read_char): Remove unused var.
19682 * eval.c: Port to Windows vsnprintf (Bug#8435).
19683 Include <limits.h>.
19684 (SIZE_MAX): Define if the headers do not.
19685 (verror): Do not give up if vsnprintf returns a negative count.
19686 Instead, grow the buffer. This ports to Windows vsnprintf, which
19687 does not conform to C99. Problem reported by Eli Zaretskii.
19688 Also, simplify the allocation scheme, by avoiding the need for
19689 calling realloc, and removing the ALLOCATED variable.
19691 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19693 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19694 But keep the doprint source code for now, as we might revamp it
19695 and use it again (Bug#8435).
19696 * lisp.h (doprnt): Remove.
19697 * Makefile.in (base_obj): Remove doprnt.o.
19698 * deps.mk (doprnt.o): Remove.
19700 error: Print 32- and 64-bit integers portably (Bug#8435).
19701 Without this change, on typical 64-bit hosts error ("...%d...", N)
19702 was used to print both 32- and 64-bit integers N, which relied on
19703 undefined behavior.
19704 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19705 * lisp.h (error, verror): Mark as printf-like functions.
19706 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19707 Report overflow in size calculations when allocating printf buffer.
19708 Do not truncate output string at its first null byte.
19709 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19710 Truncate the output at a character boundary, since vsnprintf does not
19712 * charset.c (check_iso_charset_parameter): Convert internal
19713 character to string before calling 'error', since %c now has the
19715 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19716 overflow when computing char to be passed to 'error'. Do not
19717 pass Lisp_Object to 'error'; pass the integer instead.
19718 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19719 formatted with plain %d.
19721 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19723 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19725 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19727 * xterm.c (x_catch_errors): Remove duplicate declaration.
19729 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19731 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19733 2011-04-10 Jim Meyering <meyering@redhat.com>
19735 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19736 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19737 return ssize_t not "int", and use size_t as the buffer length.
19738 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19739 * gnutls.h: Update declarations.
19740 * process.c (read_process_output): Use ssize_t, to match.
19741 (send_process): Likewise.
19743 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19745 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19747 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19749 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19750 Use unsigned char, to match FcChar8 type definition.
19752 * xterm.c (handle_one_xevent):
19753 * xmenu.c (create_and_show_popup_menu):
19754 * xselect.c (x_decline_selection_request)
19755 (x_reply_selection_request): Avoid type-punned deref of X events.
19757 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19759 Fix some uses of `int' instead of EMACS_INT.
19760 * search.c (string_match_1, fast_string_match)
19761 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19762 (scan_buffer, find_next_newline_no_quit)
19763 (find_before_next_newline, search_command, Freplace_match)
19764 (Fmatch_data): Make some `int' variables be EMACS_INT.
19766 * xdisp.c (display_count_lines): 3rd argument and return value now
19767 EMACS_INT. All callers changed.
19768 (pint2hrstr): Last argument is now EMACS_INT.
19770 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19771 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19772 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

19775 (decode_coding_ccl, decode_coding_charset)
19776 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
19777 (decode_coding_iso_2022, decode_coding_emacs_mule)
19778 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
19779 <char_offset, last_offset>: Declare EMACS_INT.

19782 (encode_designation_at_bol, encode_coding_iso_2022)
19783 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19784 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19786 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19787 (encode_invocation_designation): Last argument P_NCHARS is now
19789 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19790 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19792 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19795 * ccl.c (Fccl_execute_on_string): Declare some variables
19798 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19800 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19802 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19804 * process.c (Fformat_network_address): Doc fix.
19806 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19808 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19810 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19812 * keyboard.c (read_char): Call Lisp function help-form-show,
19813 instead of using internal_with_output_to_temp_buffer.
19814 (Qhelp_form_show): New var.
19815 (syms_of_keyboard): Use DEFSYM macro.
19817 * print.c (internal_with_output_to_temp_buffer): Function deleted.
19819 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
19821 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19823 * process.c (Flist_processes): Remove to Lisp.
19824 (list_processes_1): Delete.
19826 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19828 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19830 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19832 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19834 Fix more problems found by GCC 4.6.0's static checks.

19838 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19840 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19842 * xdisp.c (vmessage): Mark as a printf-like function.
19844 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19846 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19848 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19849 printf-like functions.
19850 (tiff_load): Add casts to remove these marks before passing them
19851 to system-supplied API.
19853 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19855 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19856 This avoids several warnings with gcc -Wstrict-overflow.
19857 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19858 directly, rather than having caller test rule sign. This avoids
19859 some unnecessary tests.
19860 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19861 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19862 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19864 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19865 (xfont_open): Avoid unnecessary tests.
19867 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19869 * composite.h, composite.c (composition_gstring_put_cache):
19870 Use EMACS_INT, not int, for length.

19873 breaking out part of COMPOSITION_DECODE_RULE.
19874 (COMPOSITION_DECODE_RULE): Use it.

19876 by using the new macro.
19878 * textprop.c (set_text_properties_1): Change while to do-while,
19879 since the condition is always true at first.
19881 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19882 (interval_deletion_adjustment): Return unsigned value.
19885 * process.c (list_processes_1, create_pty, read_process_output):

19895 (update_syntax_table): Use unsigned instead of int.
19897 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19898 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19899 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19901 * print.c (print_error_message): Avoid int overflow.
19903 * font.c (font_list_entities): Redo for clarity,
19904 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19906 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19907 (font_score): Avoid potential overflow in diff calculation.
19909 * fns.c (substring_both): Remove var that is set but not used.
19910 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19912 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19914 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19915 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19916 can always succeed if overflow has undefined behavior.
19918 * search.c (boyer_moore, wordify): Remove vars set but not used.
19919 (wordify): Omit three unnecessary tests.
19921 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19922 All callers changed. This avoids the need for an unused var.
19924 * casefiddle.c (casify_region): Remove var that is set but not used.
19926 * dired.c (file_name_completion): Remove var that is set but not used.
19928 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19930 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19931 (Finsert_file_contents): Remove unnecessary code checking fd.
19933 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19934 Check for integer overflow on size calculations.
19936 * buffer.c (Fprevious_overlay_change): Remove var that is set
19939 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19940 Remove vars that are set but not used.
19941 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19942 (timer_check_2): Mark vars as initialized.
19944 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19946 * image.c (lookup_image): Remove var that is set but not used.
19947 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19949 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19950 that are set but not used.
19952 * xfns.c (make_invisible_cursor): Don't return garbage
19953 if XCreateBitmapFromData fails (Bug#8410).
19955 * xselect.c (x_get_local_selection, x_handle_property_notify):
19956 Remove vars that are set but not used.
19958 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19959 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19961 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19962 Remove var that is set but not used.

19964 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19965 Check for overflow.
19967 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19968 (map_tty_color) [!defined MSDOS]: Likewise.
19970 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19972 * coding.c: Remove vars that are set but not used.
19973 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19974 All callers changed.
19975 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19976 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19977 (decode_coding_charset): Remove vars that are set but not used.
19979 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19980 that is set but not used.
19982 * print.c (print_object): Remove var that is set but not used.
19984 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19985 The gnulib version avoids calling malloc in the usual case,
19986 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19987 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19988 * filelock.c (current_lock_owner): Likewise.
19989 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19990 * sysdep.c: Include allocator.h, careadlinkat.h.
19991 (emacs_no_realloc_allocator): New static constant.
19992 (emacs_readlink): New function.
19993 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19994 ../lib/careadlinkat.h.
19996 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19998 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19999 first non-nil return value).

20008 * xdisp.c (display_count_lines): Remove parameter `start',
20009 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

20015 (get_per_char_metric): Remove parameter `f', unused since
20016 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20018 2011-04-02 Jim Meyering <meyering@redhat.com>
20020 do not dereference NULL upon failed strdup
20021 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20022 (ns_get_family): Likewise.
20024 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20026 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20028 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20030 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20033 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20035 Add lexical binding.
20037 * window.c (Ftemp_output_buffer_show): New fun.
20038 (Fsave_window_excursion):
20039 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20041 * lread.c (lisp_file_lexically_bound_p): New function.
20042 (Fload): Bind Qlexical_binding.
20043 (readevalloop): Remove `evalfun' arg.
20044 Bind Qinternal_interpreter_environment.
20045 (Feval_buffer): Bind Qlexical_binding.
20046 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20048 (syms_of_lread): Declare `lexical-binding'.
20050 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20052 * keyboard.c (eval_dyn): New fun.
20053 (menu_item_eval_property): Use it.
20055 * image.c (parse_image_spec): Use Ffunctionp.
20057 * fns.c (concat, mapcar1): Accept byte-code-functions.
20059 * eval.c (Fsetq): Handle lexical vars.
20060 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20061 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20062 (FletX, Flet): Obey lexical binding.
20063 (Fcommandp): Handle closures.
20064 (Feval): New `lexical' arg.
20065 (eval_sub): New function extracted from Feval. Use it almost
20066 everywhere where Feval was used. Look up vars in lexical env.
20068 (Ffunctionp): Move from subr.el.
20069 (Ffuncall): Handle closures.
20070 (apply_lambda): Remove `eval_flags'.
20071 (funcall_lambda): Handle closures and new byte-code-functions.
20072 (Fspecial_variable_p): New function.
20073 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20074 but without exporting it to Lisp.
20076 * doc.c (Fdocumentation, store_function_docstring):
20077 * data.c (Finteractive_form): Handle closures.
20079 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20082 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20084 (exec_byte_code): New function extracted from Fbyte_code to handle new
20085 calling convention for byte-code-functions. Add new byte-codes.
20087 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20089 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20091 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20093 * xdisp.c (redisplay_internal): Fix prototype.
20095 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20097 * xdisp.c (SCROLL_LIMIT): New macro.
20098 (try_scrolling): Use it when setting scroll_limit.
20099 Limit scrolling to 100 screen lines.
20100 (redisplay_window): Even when falling back on "recentering",
20101 position point in the window according to scroll-conservatively,
20102 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20104 (try_scrolling): When point is above the window, allow searching
20105 as far as scroll_max, or one screenful, to compute vertical
20106 distance from PT to the scroll margin position. This prevents
20107 try_scrolling from unnecessarily failing when
20108 scroll-conservatively is set to a value slightly larger than the
20109 window height. Clean up the case of PT below the margin at bottom
20110 of window: scroll_max can no longer be INT_MAX. When aggressive
20111 scrolling is in use, don't let point enter the opposite scroll
20112 margin as result of the scroll.
20113 (syms_of_xdisp) <scroll-conservatively>: Document the
20114 threshold of 100 lines for never-recentering scrolling.
20116 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20118 * dispextern.h (move_it_by_lines):
20119 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

20121 (message_log_check_duplicate): Remove parameters `prev_bol' and
20122 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20123 (redisplay_internal): Remove parameter `preserve_echo_area',
20124 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20126 * indent.c (Fvertical_motion):
20127 * window.c (window_scroll_pixel_based, Frecenter):
20128 Don't pass `need_y_p' to `move_it_by_lines'.
20130 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20132 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20133 steal a few bits to be more compact.
20134 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20135 Remove unneeded casts.
20137 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20139 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20141 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20142 binding" message (bug#7967).
20144 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20146 Fix more problems found by GCC 4.6.0's static checks.
20148 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20149 Remove unused local var.
20151 * editfns.c (Fmessage_box): Remove unused local var.
20153 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20154 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20155 Omit unused local vars.
20156 * window.c (shrink_windows): Omit unused local var.
20157 * menu.c (digest_single_submenu): Omit unused local var.
20158 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20159 Omit unused local var.
20161 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20162 Don't assume string length fits in int.
20163 (keyremap_step, read_key_sequence): Use size_t for sizes.
20164 (read_key_sequence): Don't check last_real_key_start redundantly.
20166 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20167 instead of alloca (Bug#8344).
20169 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20170 (Fbacktrace_frame): Don't assume nframes fits in int.
20172 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

20179 * cm.c (calccost): Turn while-do into do-while, for clarity.
20181 * keyboard.c (syms_of_keyboard): Use the same style as later
20182 in this function when indexing through an array. This also
20183 works around GCC bug 48267.
20185 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20187 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20189 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20190 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20192 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20193 This avoids undefined behavior on integer overflow, and is a bit
20194 more convenient anyway since it is compared to a size_t variable.
20196 Variadic C functions now count arguments with size_t, not int.
20197 This avoids an unnecessary limitation on 64-bit machines, which
20198 caused (substring ...) to crash on large vectors (Bug#8344).

20208 * fns.c (concat): Likewise.
20209 * frame.c (x_set_frame_parameters): Likewise.
20210 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20211 0 if not found, not -1. All callers changed.
20213 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20214 (stack_copy_size): Now size_t, not int.
20215 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20217 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20219 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

20236 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20237 don't set the hook to nil, but remove the offending function instead.
20238 (Qcommand_hook_internal): Remove, unused.
20239 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20240 Vcommand_hook_internal.
20242 * eval.c (enum run_hooks_condition): Remove.
20243 (funcall_nil, funcall_not): New functions.
20244 (run_hook_with_args): Call each function through a `funcall' argument.
20245 Remove `cond' argument, now redundant.
20246 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
20247 (Frun_hook_with_args_until_failure): Adjust accordingly.
20248 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

20271 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.

20421 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20423 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20424 unconditionally since it does the check itself.
20426 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20428 Fix more problems found by GCC 4.5.2's static checks.
20430 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20431 the first time through the loop, since we know p0 < p1 then.
20432 This also avoids a gcc -Wstrict-overflow warning.
20434 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20435 leading to a memory leak, possible in functions like
20436 load_charset_map_from_file that can allocate an unbounded number
20437 of objects (Bug#8318).
20439 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20440 that could (at least in theory) be that large.
20442 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20443 This is less likely to overflow, and avoids undefined behavior if
20444 overflow does occur. All callers changed. Use strtoul to scan
20445 for the unsigned long integer.
20446 (pint2hrstr): Simplify and tune code slightly.
20447 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
20449 * scroll.c (do_scrolling): Work around GCC bug 48228.
20450 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

20455 This also avoids a warning with gcc -Wstrict-overflow.
20457 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20460 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20462 * process.c (Fmake_network_process): Use socklen_t, not int,
20463 where POSIX says socklen_t is required in portable programs.
20464 This fixes a porting bug on hosts like 64-bit HP-UX, where
20465 socklen_t is wider than int (Bug#8277).
20466 (Fmake_network_process, server_accept_connection):
20467 (wait_reading_process_output, read_process_output):
20470 * process.c: Rename or move locals to avoid shadowing.

20480 Make tparam.h and terminfo.c consistent.
20481 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20482 Include tparam.h instead, since it declares them.
20483 * cm.h (PC): Remove extern decl; tparam.h now does this.
20484 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20485 * terminfo.c: Include tparam.h, to check interfaces.
20486 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20487 (tparam): Adjust signature to match interface in tparam.h;
20488 this removes some undefined behavior. Check that outstring and len
20489 are zero, which they always are with Emacs.
20490 * tparam.h (PC, BC, UP): New extern decls.
20492 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20493 (xftfont_open): Rename locals to avoid shadowing.

20511 (composition_update_it): Mark var as initialized.
20512 (find_automatic_composition): Mark vars as initialized,
20513 with a FIXME (Bug#8290).

20519 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20520 to avoid shadowing.
20522 * textprop.c (property_change_between_p): Remove; unused.
20524 * intervals.c (interval_start_pos): Now static.
20526 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20532 Fix pointer signedness.
20533 (alsa_choose_format): Remove unused local var.
20534 (wav_play): Initialize a variable to 0, to prevent undefined
20535 behavior (Bug#8278).
20537 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20539 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20541 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20542 clobbering (Bug#8298).
20543 * sysdep.c (sys_subshell): Likewise.
20544 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20546 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20547 This should get cleaned up, so that child_setup has the
20548 same signature on all platforms.
20550 * callproc.c (call_process_cleanup): Now static.
20551 (relocate_fd): Rename locals to avoid shadowing.
20553 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20555 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20556 not to be necessary, and produces flickering.
20558 2011-03-20 Glenn Morris <rgm@gnu.org>
20560 * config.in: Remove file.
20562 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20564 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20565 are now in src/globals.h.
20566 (syms_of_minibuf): Remove spurious & from previous change.

20576 * xfaces.c (Fx_load_color_file):
20577 Read color file from absolute filename (bug#8250).
20579 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
20581 * makefile.w32-in: Update dependencies.
20583 2011-03-17 Eli Zaretskii <eliz@gnu.org>

20592 (sigchld_handler): Now static.
20594 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20595 That way, the code declares only the vars that it needs.

20605 (CONSTANTLIM): Remove; unused.
20606 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20607 Define only if needed.
20609 * unexelf.c (unexec): Name an expression,
20610 to avoid gcc -Wbad-function-cast warning.
20611 Use a different way to cause a compilation error if anyone uses
20612 n rather than nn, a way that does not involve shadowing.
20613 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20615 * deps.mk (unexalpha.o): Remove; unused.
20617 New file unexec.h, the (simple) interface for unexec (Bug#8267).
20618 * unexec.h: New file.
20619 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
20620 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
20621 Depend on unexec.h.
20622 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
20623 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
20624 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
20625 Change as necessary to match prototype in unexec.h.
20627 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

20672 * callint.c (quotify_arg, quotify_args): Now static.
20673 (Fcall_interactively): Rename locals to avoid shadowing.

20680 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
20681 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20682 some of which prompt warnings from gcc -Wbad-function-cast.
20683 (Fformat_time_string, Fencode_time, Finsert_char):
20684 (Ftranslate_region_internal, Fformat):
20685 Rename or remove local vars to avoid shadowing.

20688 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20691 * lisp.h (eassert): Check that the argument compiles, even if
20692 ENABLE_CHECKING is not defined.
20694 * data.c (Findirect_variable): Name an expression, to avoid
20695 gcc -Wbad-function-cast warning.

20704 Rename locals to avoid shadowing.
20705 (mark_stack): Move local variables into the #ifdef region where
20707 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
20708 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
20710 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
20711 (GC_STRING_CHARS): Remove; not used.
20712 (Fmemory_limit): Cast sbrk's returned value to char *.
20714 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
20715 avoids undefined behavior in theory.
20717 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
20719 Use functions, not macros, for up- and down-casing (Bug#8254).
20720 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20721 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20722 to use the following functions instead of these macros.
20723 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20724 EMACS_INT, since callers assume the returned value fits in int.
20725 (upcase1): Likewise, for UPCASE_TABLE.
20726 (uppercasep, lowercasep, upcase): New static inline functions.
20727 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20736 which gcc can warn about.
20737 (regex_compile, re_match_2_internal): Mark locals as initialized.
20738 (RETALLOC_IF): Define only if needed.
20739 (WORDCHAR_P): Likewise. This one is never needed, but is used
20740 only in a comment talking about a compiler bug, so put inside
20741 the #if 0 of that comment.
20742 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20743 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
20746 * search.c (boyer_moore): Rename locals to avoid shadowing.
20747 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

20769 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20770 New macros, so that the caller can use some names other than
20771 gcpro1, gcpro2, etc.
20772 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20774 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20775 argument, for consistency with GCPRO2_VAR, etc: it is now the
20776 prefix of the variable, not the variable itself. All uses
20778 * dired.c (directory_files_internal, file_name_completion):
20779 Rename locals to avoid shadowing.
20781 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20782 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20783 dired.c's scmp function, had undefined behavior.
20784 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20785 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20786 * buffer.h: ... to here, because these macros use current_buffer,
20787 and the new implementation with inline functions needs to have
20788 current_buffer in scope now, rather than later when the macros
20790 (downcase, upcase1): New static inline functions.
20791 (DOWNCASE, UPCASE1): Reimplement using these functions.
20792 This avoids undefined behavior in expressions like
20793 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20794 from race conditions in accessing the global variables
20795 case_temp1 and case_temp2.
20796 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20797 * lisp.h (case_temp1, case_temp2): Remove their decls.
20798 * character.h (ASCII_CHAR_P): Move from here ...
20799 * lisp.h: ... to here, so that the inline functions mentioned
20800 above can use them.
20802 * dired.c (directory_files_internal_unwind): Now static.
20804 * fileio.c (file_name_as_directory, directory_file_name):

20807 (file_name_as_directory): Use const pointers when appropriate.
20808 (Fexpand_file_name): Likewise. In particular, newdir might
20809 point at constant storage, so make it a const pointer.
20810 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20811 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20813 (Fset_file_times, Finsert_file_contents, auto_save_error):
20814 Rename locals to avoid shadowing.
20816 * minibuf.c (choose_minibuf_frame_1): Now static.
20817 (Ftry_completion, Fall_completions): Rename or remove locals
20818 to avoid shadowing.
20820 * marker.c (bytepos_to_charpos): Remove; unused.
20822 * lisp.h (verify_bytepos, count_markers): New decls,
20823 so that gcc does not warn that these functions aren't declared.
20825 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20826 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20827 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20828 (copy_text): Remove unused local var.
20830 * filelock.c (within_one_second): Now static.
20831 (lock_file_1): Rename local to avoid shadowing.
20833 * buffer.c (fix_overlays_before): Mark locals as initialized.
20834 (fix_start_end_in_overlays): Likewise. This function should be
20835 simplified by using pointers-to-pointers, but that's a different
20837 (switch_to_buffer_1): Now static.
20838 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20839 (report_overlay_modification): Rename locals to avoid shadowing.
20841 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
20842 Fix pointer signedness issue.
20843 (sys_subshell): Mark local as volatile if checking for lint,
20844 to suppress a gcc -Wclobbered warning that does not seem to be right.
20845 (MAXPATHLEN): Define only if needed.
20847 * process.c (serial_open, serial_configure): Move decls from here ...
20848 * systty.h: ... to here, so that they can be checked.
20850 * fns.c (get_random, seed_random): Move extern decls from here ...
20851 * lisp.h: ... to here, so that they can be checked.
20853 * sysdep.c (reset_io): Now static.
20854 (wait_for_termination_signal): Remove; unused.
20856 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
20857 (copy_keymap_item, append_key, push_text_char_description):
20859 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
20860 (DENSE_TABLE_SIZE): Remove; unused.
20861 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20862 (describe_map_tree):
20863 Rename locals to avoid shadowing.
20865 * keyboard.c: Declare functions static if they are not used elsewhere.
20866 (echo_char, echo_dash, cmd_error, top_level_2):
20867 (poll_for_input, handle_async_input): Now static.
20868 (read_char, kbd_buffer_get_event, make_lispy_position):
20869 (make_lispy_event, make_lispy_movement, apply_modifiers):
20870 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
20871 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
20872 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
20873 (read_key_sequence, read_char): Mark locals as initialized.

20878 * alloc.c (mark_kboards): ... from here.
20880 * lisp.h (force_auto_save_soon): New decl.
20882 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
20883 (DEFINE_DUMMY_FUNCTION): New macro.
20884 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
20886 (main): Add casts to avoid warnings
20887 if GCC considers string literals to be constants.
