21 Avoid unnecessary byte position calculation for the gap movement.
22 Since all users of move_gap do CHAR_TO_BYTE for other purposes
23 anyway, all of them should use move_gap_both instead.
24 * lisp.h (move_gap): Remove prototype.
25 * insdel.c (move_gap): Remove.
26 (move_gap_both): Add eassert.
27 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

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

56 * buffer.c (buffer_slot_type_mismatch): Remove.
57 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
58 predicate. Adjust comment.
59 (syms_of_buffer): Use Qsymbolp for major-mode. Use Qintegerp for
60 fill-column, left-margin, tab-width, buffer-saved-size,
61 left-margin-width, right-margin-width, left-fringe-width,

63 Use Qstringp for default-directory, buffer-file-name,
64 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
65 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
67 * data.c (store_symval_forwarding): Adjust to call the predicate.
69 2013-01-09 Juanma Barranquero <lekktu@gmail.com>

85 * coding.c (coding_alloc_by_making_gap): Use it.
86 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
87 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
89 2013-01-08 Juri Linkov <juri@jurta.org>
91 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
92 of (supports :underline (:style wave)). (Bug#13000)

110 trailing dash is properly added.
112 2013-01-05 Eli Zaretskii <eliz@gnu.org>
114 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
115 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
116 digits for buffer positions, before misalignment starts.
117 Display "0" for integer "object" field.
118 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
119 Display the newline glyph more unambiguously.
121 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
123 * nsterm.m (ns_draw_underwave):
124 * w32term.c (w32_draw_underwave):
125 * xterm.c (x_draw_underwave): Make underwave look more triangular
126 and also degrade gracefully for small fonts. (Bug#13000)
128 * nsterm.m (ns_draw_text_decoration):
129 * w32term.c (x_draw_glyph_string):
130 * xterm.c (x_draw_glyph_string): Don't use previous underline
131 thickness and position if previous underline type is underwave.
133 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
135 * fileio.c (Ffile_acl): Undocument return format.

139 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
141 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
144 * dired.c (file_name_completion):
145 * doc.c (get_doc_string):

150 * minibuf.c (Ftry_completion):
151 * term.c (tty_ins_del_lines):
152 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
153 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
155 2012-12-31 Eli Zaretskii <eliz@gnu.org>
157 * w32.c (unsetenv): Set up the string passed to _putenv
159 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
160 for the bug this caused.
162 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
164 * coding.c (Qmac): Now static.
166 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
168 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
169 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
170 handlebox_widget. Set toolbar_in_hbox to false/true, set
171 toolbar_is_packed to true.
172 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
173 (update_frame_tool_bar): Check toolbar_is_packed for packing.
174 Show all on TOOLBAR_TOP_WIDGET.
175 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned

177 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
178 Check toolbar_is_packed.
179 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
180 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
181 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
183 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
184 (xg_update_menubar): Update title only if
185 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
186 (xg_update_submenu): Skip tearoff only if
187 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
188 (xg_initialize): Initialize xg_detached_menus only if
189 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
191 * xterm.h (struct x_output): Surround handlebox_widget with
192 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
193 toolbar_in_hbox is bool.
195 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
197 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
198 (LIBS_GNUSTEP): Define.
199 (LIBES): Add $(LIBS_GNUSTEP).

202 2012-12-30 Eli Zaretskii <eliz@gnu.org>
204 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
205 continuation glyph on a TTY with an indication of an empty line.
208 2012-12-29 Eli Zaretskii <eliz@gnu.org>
210 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
211 file's SELinux context or ACLs successfully set, nil otherwise.
213 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
215 * w32proc.c (reader_thread): Avoid passing NULL handles to
216 SetEvent and WaitForSingleObject.
218 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
220 Port EXTERNALLY_VISIBLE to Clang 3.2.
221 * conf_post.h (__has_attribute): New macro.
222 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
224 2012-12-27 Glenn Morris <rgm@gnu.org>
226 * cygw32.c (Fcygwin_convert_file_name_to_windows)
227 (Fcygwin_convert_file_name_from_windows): Doc fixes.
229 2012-12-27 Eli Zaretskii <eliz@gnu.org>
231 * fileio.c (file_name_as_directory, directory_file_name):
232 Accept an additional argument MULTIBYTE to indicate whether the input C
233 came from a multibyte or a unibyte Lisp string; all callers
234 adjusted. Don't assume the input string is always multibyte.
236 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
237 don't ENCODE_FILE them, and return a unibyte string if the input
239 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
240 don't assume the input strings will always be multibyte. If the
241 input strings are multibyte, decode strings obtained from C
244 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
246 * lisp.h (toplevel): Add two notices to the comment about
247 defining a new Lisp data type.
248 * print.c (print_object): If Lisp_Save_Value object's pointer
249 is the address of a memory area containing Lisp_Objects, try
251 * alloc.c (valid_lisp_object_p): Adjust comment.
253 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
255 * keyboard.c (record_asynch_buffer_change): Initialize an event
256 only if it's really needed.
257 * frame.h (enum output_method): Remove output_mac member since
258 it's a leftover from the deleted code.
259 * frame.c (Fframep): Adjust user here ...
260 * terminal.c (Fterminal_live_p): ... and here.
261 * coding.c (Qmac): Now here because it's only used to denote
262 end-of-line encoding type.
263 (syms_of_coding): DEFSYM it.
264 * frame.h (Qmac): Remove duplicated declaration.
266 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
268 * window.c (select_window_1): Now static, since it's used only here.
270 2012-12-25 Eli Zaretskii <eliz@gnu.org>
272 * window.c (window_body_cols): Subtract display margins from the
273 window body width on TTYs as well. See
274 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
275 for the original report.
277 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
279 * xdisp.c (redisplay_window): Remove inner local variable
280 because the outer shadowed one has the same meaning.
281 * xterm.h (struct x_output): Remove toolbar_detached member since it's
283 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
284 (xg_create_tool_bar): Adjust users.
286 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
288 * buffer.h (BUF_COMPACT): New macro to follow the common style.
289 * buffer.c (Fget_buffer_create): Use it to set compact field of
290 struct buffer_text to avoid accessing an uninitialized value
291 when compact_buffer is called for the first time.
292 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
293 (Fset_buffer_modified_p): Use buffer_window_count to check
294 whether the buffer is displayed in some window.
295 * xdisp.c (message_dolog): Likewise.
297 2012-12-23 Eli Zaretskii <eliz@gnu.org>
299 * w32.c (acl_set_file): If setting the file security descriptor
300 fails, and the new DACL is identical to the existing one, silently
301 return success. This fixes problems for users backing up their
302 own files without having the necessary privileges for setting
303 security descriptors.
305 * w32proc.c (reader_thread): Do not index fd_info[] with negative
307 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
308 after WaitForSingleObject returns normally. This expedites reader
309 thread shutdown when delete_child triggers it.
310 (reap_subprocess): More accurate commentary for why we call
311 delete_child only when cp->fd is negative.
313 * w32.c (sys_close): Do not call delete_child on a subprocess
314 whose handle is not yet closed. Instead, set its file descriptor
315 to a negative value, so that reap_subprocess will call
316 delete_child on that subprocess when its SIGCHLD arrives.
317 This avoids closing handles used for communications between sys_select
318 and reader_thread, which doesn't give sys_select a chance to
319 notice that the process exited and invoke the SIGCHLD handler for
322 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
324 * nsfns.m (Fns_do_applescript): Run event loop until script has
325 been executed (Bug#12969).
326 (ns_run_ascript): Chech as_script for nil, set to nil after
329 2012-12-22 Martin Rudalics <rudalics@gmx.at>
331 * window.c (Fselect_window): Reword doc-string (Bug#13248).
333 2012-12-22 Eli Zaretskii <eliz@gnu.org>
335 * w32term.c (w32fullscreen_hook): New function.
336 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
338 2012-12-21 Eli Zaretskii <eliz@gnu.org>
340 * fileio.c (Finsert_file_contents): Doc fix.
342 * w32proc.c (new_child, delete_child, find_child_pid): For a
343 subprocess, consider its slot being in use as long as its process
344 handle (procinfo.hProcess) is not NULL. This avoids reusing the
345 slot when a new process is started immediately after killing
346 another one, without waiting enough time for the first process to
347 be reaped and resources allocated for it be orderly freed.
349 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
351 2012-12-21 Chong Yidong <cyd@gnu.org>
353 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
355 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
357 2012-12-21 Eli Zaretskii <eliz@gnu.org>
359 * w32.c (get_name_and_id): Always pass NULL as the first argument
360 of lookup_account_sid. Avoids crashes with UNC file names that
361 refer to DFS domains, not to specific machine names. (Bug#12621)
362 Remove now unused argument FNAME; all callers changed.
363 (get_file_owner_and_group): Remove now unused argument FNAME; all
366 2012-12-21 Chong Yidong <cyd@gnu.org>
368 * editfns.c (Finsert_char): Since read-char-by-name now signals an
369 error for invalid chars, don't check for a nil return value.
371 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
373 Avoid calls to CHAR_TO_BYTE if byte position is known.
374 * editfns.c (make_buffer_string_both): Use move_gap_both.
375 (Fbuffer_string): Use make_buffer_string_both.
376 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
378 (buf_bytepos_to_charpos): Likewise.

380 * fileio.c (Finsert_file_contents): Use move_gap_both.
381 * search.c (Freplace_match): Likewise.
382 * process.c (process_send_region): Likewise. Use convenient
383 names for byte positions.
384 * lisp.h (charpos_to_bytepos): Remove prototype.
385 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
386 * insdel.c (move_gap): Likewise.

395 (redisplay_internal): Don't bother selecting the frame to get the
396 proper value of frame-local variables (bug#13225).
398 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
400 * textprop.c (set_text_properties_1): Do not allow NULL interval.
401 Rename 4th argument since it may be buffer or string. Adjust comment.
402 * intervals.c (graft_intervals_info_buffer): Find an interval here.
404 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
406 * coding.c (Fdetect_coding_region): Do not check start and end with
407 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
408 (code_convert_region): Likewise.
410 2012-12-18 Eli Zaretskii <eliz@gnu.org>
412 * w32.c (acl_get_file, acl_set_file): Run the file name through
413 map_w32_filename, and resolve any symlinks in the file name, like
415 (acl_set_file): Call revert_to_self, if any privileges were
418 2012-12-17 Juanma Barranquero <lekktu@gmail.com>

421 ($(BLD)/w32.$(O)): Update dependencies.
423 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
425 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
426 propagate redisplay's scrolling (if any) to the right window.
427 (redisplay_internal): Use ensure_selected_frame.
428 (display_mode_lines): Complete last fix.
429 * window.c (select_window_1): New func, extracted from select_window.
430 (select_window): Use it.
431 * window.h (select_window_1): Declare.
433 2012-12-17 Eli Zaretskii <eliz@gnu.org>

457 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
459 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
460 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
461 for some of that bug's symptoms can now cause Emacs to abort.
462 Remove the workaround.
463 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
464 The bug that caused SIGCHLD to get lost has been fixed, and the
465 workaround for it can now cause Emacs to abort.
467 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
469 * sysdep.c (emacs_abort): Bump backtrace size to 40.
470 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
471 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

497 (delete_child): Delete the child's temporary input file, if any,
498 that is pending deletion.
499 (register_child): First argument is now pid_t.
500 (record_infile, record_pending_deletion): New functions.
501 (reap_subprocess): Fix a typo in DebPrint string.
502 (sys_spawnve, sys_kill): Use pid_t for PID arguments.

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

526 Fix permissions bugs with setgid directories etc. (Bug#13125)
527 * dired.c (Ffile_attributes): Return t as the 9th attribute,
528 to mark it as a placeholder. The old value was often wrong.
529 The only user of this attribute has been changed to use
530 file-ownership-preserved-p instead, with its new group arg.
531 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

540 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
541 try to get accurate owner and group information from NT file
542 security APIs. This is to make most callers of 'stat' and
543 'lstat', which don't need that information, much faster.
545 * dired.c (Ffile_attributes) [WINDOWSNT]:
546 Set w32_stat_get_owner_group to a non-zero value, to request accurate
547 owner and group information from 'lstat'.
549 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
551 * fileio.c (Finsert_file_contents): Don't put tail into head area,
552 as that confuses set-auto-coding, so insist on the head-read
553 returning the full 1024 bytes. Let lseek compute the tail offset;
554 less work for us. Do not ignore I/O errors when reading the tail.
556 * xdisp.c: Minor style fixes.
557 (init_iterator): Hoist assignment out of if-expression.
558 (markpos_of_region): Callers now test for sign, not for -1.

581 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
583 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
584 fstat shouldn't fail, and if it does fail copy-file should not proceed.
585 Remove unnecessary S_ISLNK test, as (contra the comments) this
586 function can't copy symlinks. Improve quality of error message
587 when attempting to copy files that are neither regular files nor

598 2012-12-12 Daniel Colascione <dancol@dancol.org>
600 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
601 the dumped Emacs is not a sparse file, greatly improving Cygwin

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

632 2012-12-11 Eli Zaretskii <eliz@gnu.org>
634 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
635 encoded_file_name, which is what it is.
637 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
639 Consistently use marker_position and marker_byte_position.

660 * w32term.c, keyboard.c: Fix build break in cygw32 by omitting
661 Windows file notification functionality unless WINDOWSNT.
663 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
666 * w32fns.c (cache_system_info): Initialize the global hinst
667 variable here so various initialization calls DTRT.
669 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
670 (hinst): Remove unneeded extern declaration.
671 (_start): Remove initialization of above variables; remove
672 initialization of hinst, as cache_system_info now does that.
674 * emacs.c (main): Call cache_system_info early in startup; we
675 previously weren't calling it in Cygwin builds.
677 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):

704 Support for filesystem notifications on MS-Windows.
705 * w32proc.c (sys_select): If drain_message_queue returns non-zero,
706 and this is a TTY frame, signal the caller that keyboard input is
709 * w32xfns.c (drain_message_queue): Now returns an int: an
710 indication whether any WM_EMACS_FILENOTIFY messages were found in

800 displayed on the left or the right margin, don't consider it as a
801 factor in cursor positioning. (Bug#13108)

814 * w32.c (unsetenv): Return 0 if the input string is too long.
816 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>

833 no longer needed here.
834 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:

836 (set_time_zone_rule): Maintain the TZ=value string separately.
837 (syms_of_editfns): Don't initialize initial_tz;
838 init_editfns now does it.

892 * window.c (Fsplit_window_internal): Likewise. Previously it was

913 * frame.h (x_char_width, x_char_height): Remove prototypes.

927 * callproc.c, process.h (record_kill_process):
928 New function, containing part of the old call_process_kill.
929 (call_process_kill): Use it.
930 This does not change call_process_kill's behavior.
931 * process.c (Fdelete_process): Use record_kill_process to fix a
932 race condition that could cause Emacs to lose track of a child.
934 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
936 Avoid code duplication between prev_frame and next_frame.
937 * frame.c (candidate_frame): New function. Add comment.
938 (prev_frame, next_frame): Use it. Adjust comment.
940 2012-12-06 Eli Zaretskii <eliz@gnu.org>
942 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
943 fails, signal an error instead of continuing with an empty
945 Encode expanded temp file pattern before passing it to mkstemp or
948 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
949 Encode the file name before passing it to dostounix_filename, in
950 case it will downcase it (under w32-downcase-file-names).
953 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
955 Minor call-process cleanups.
956 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
957 at the same time as other platforms, to simplify analysis.
958 No need for fd0_volatile since we have synch_process_fd.
959 Avoid needless emacs_close; arg is always negative.

963 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
966 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>

979 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
981 Don't let call-process be a zombie factory (Bug#12980).
982 Fixing this bug required some cleanup of the signal-handling code.
983 As a side effect, this change also fixes a longstanding rare race
984 condition whereby Emacs could mistakenly kill unrelated processes,
985 and it fixes a bug where a second C-g does not kill a recalcitrant
986 synchronous process in GNU/Linux and similar platforms.
987 The patch should also fix the last vestiges of Bug#9488,
988 a bug which has mostly been fixed on the trunk by other changes.
989 * callproc.c, process.h (synch_process_alive, synch_process_death)
990 (synch_process_termsig, sync_process_retcode):
991 Remove. All uses removed, to simplify analysis and so that
992 less consing is done inside critical sections.
993 * callproc.c (call_process_exited): Remove. All uses replaced
994 with !synch_process_pid.
995 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
996 These take the role of what used to be in unwind-protect arg.
998 (block_child_signal, unblock_child_signal):
999 New functions, to avoid races that could kill innocent-victim processes.
1000 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1001 (call_process_kill): Record killed processes as deleted, so that
1002 zombies do not clutter up the system. Do this inside a critical
1003 section, to avoid a race that would allow the clutter.
1004 (call_process_cleanup): Fix code so that the second C-g works again
1005 on common platforms such as GNU/Linux.
1006 (Fcall_process): Create the child process in a critical section,
1007 to fix a race condition. If creating an asynchronous process,
1008 record it as deleted so that zombies do not clutter up the system.
1009 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1010 light of these changes. Omit unnecessary call to emacs_close
1011 before failure, as the unwind-protect code does that.
1012 * callproc.c (call_process_cleanup):
1013 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1014 * process.c (record_deleted_pid): New function, containing
1015 code refactored out of Fdelete_process.
1016 (Fdelete_process): Use it.
1017 (process_status_retrieved): Remove. All callers changed to use
1018 child_status_change.
1019 (record_child_status_change): Remove, folding its contents into ...
1020 (handle_child_signal): ... this signal handler. Now, this
1021 function is purely a handler for SIGCHLD, and is not called after
1022 a synchronous waitpid returns; the synchronous code is moved to
1023 wait_for_termination. There is no need to worry about reaping
1024 more than one child now.
1025 * sysdep.c (get_child_status, child_status_changed): New functions.
1026 (wait_for_termination): Now takes int * status and bool
1027 interruptible arguments, too. Do not record child status change;
1028 that's now the caller's responsibility. All callers changed.
1029 Reimplement in terms of get_child_status.
1030 (wait_for_termination_1, interruptible_wait_for_termination):
1031 Remove. All callers changed to use wait_for_termination.
1032 * syswait.h: Include <stdbool.h>, for bool.
1033 (record_child_status_change, interruptible_wait_for_termination):
1035 (record_deleted_pid, child_status_changed): New decls.
1036 (wait_for_termination): Adjust to API changes noted above.
1038 * bytecode.c, lisp.h (Qbytecode): Remove.
1039 No longer needed after 2012-11-20 interactive-p changes.
1041 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1043 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1044 the scroll margin, move point outside the margin. (Bug#13055)

1048 * gtkutil.c (my_log_handler): New function.
1049 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1051 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1053 * lisp.h (modify_region): Rename to...
1054 (modify_region_1): ...new prototype.
1055 * textprop.c (modify_region): Now static. Adjust users.
1056 * insdel.c (modify_region): Rename to...
1057 (modify_region_1): ...new function to work with current buffer.
1058 Adjust comment and users. Use true and false for booleans.
1060 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1062 * alloc.c (free_save_value): New function.
1063 (safe_alloca_unwind): Use it.
1064 * lisp.h (free_save_value): New prototype.
1065 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1067 (save_excursion_restore): Adjust to match saved data structure.
1068 Use free_save_value to offload some work from GC. Drop obsolete
1071 2012-12-03 Chong Yidong <cyd@gnu.org>
1073 * fileio.c (Vauto_save_list_file_name): Doc fix.
1075 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1077 * w32fns.c: Remove prototype of atof.
1078 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1080 (file_dialog_callback): Make it UINT_PTR.
1082 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1085 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1086 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1089 2012-12-03 Glenn Morris <rgm@gnu.org>
1091 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1093 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1095 Fix xpalloc confusion after memory is exhausted.
1096 * alloc.c (xpalloc): Comment fix.
1097 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1098 and signals an error, do not clear charset_table_size, as
1099 charset_table is still valid.
1100 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1102 Use execve to avoid need to munge environ (Bug#13054).
1103 * callproc.c (Fcall_process):
1104 * process.c (create_process):
1105 Don't save and restore environ; no longer needed.
1106 * callproc.c (child_setup):
1107 Use execve, not execvp, to preserve environ.
1109 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1111 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1113 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1115 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1116 display for sliced images (Bug#10500).
1118 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1120 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1122 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1123 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1125 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1127 * xdisp.c (window_outdated): Remove eassert since it hits
1128 some suspicious corner cases (see Bug#13007 and Bug#13012).
1129 (mode_line_update_needed): New function.
1130 (redisplay_internal, redisplay_window): Use it.
1131 (ensure_selected_frame): New function.
1132 (redisplay_internal, unwind_redisplay): Use it.
1133 (redisplay_internal): Move comment about buffer_shared...
1134 (buffer_shared_and_changed): ...near to its real use.
1136 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1138 * callproc.c (Fcall_process): Don't misreport vfork failure.
1140 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1142 * callproc.c (Fcall_process): Fix vfork portability problems.
1143 Do not assume that fd[0], count, filefd, and save_environ survive
1144 vfork. Fix bug whereby wrong errno value could be reported for
1145 pipe failure. Some minor cleanups, too, as follows. Move buf and
1146 bufsize to the context where they're needed. Change new_argv to
1147 be of type char **, as this is more convenient and avoids casts.
1148 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1149 Now local constants, not macros.
1151 2012-11-18 Kenichi Handa <handa@gnu.org>
1153 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1154 for the variable "f".

1158 * font.c (font_unparse_xlfd): Exclude special characters from the
1159 generating XLFD name.

1177 * unexcoff.c (write_segment): Assume EFAULT is defined.
1179 2012-11-27 Eli Zaretskii <eliz@gnu.org>

1184 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1185 highlighting on the frame was cleared. Prevents assertion
1186 violations when repeatedly clicking on the "Top" link of the
1187 "bread-crumbs" in Info buffers.

1201 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1202 between bpos_covered and bpos_max. This fixes cursor display when
1203 several display strings follow each other.
1205 * .gdbinit (pgx): If the glyph's object is a string, display the
1206 pointer to string data, rather than the value of the string object
1207 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1209 * indent.c (Fvertical_motion): If the starting position is covered
1210 by a display string, return to one position before that, to avoid
1211 overshooting it inside move_it_to. (Bug#12930)
1213 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1215 * frame.h (struct frame): Remove display_preempted member

1218 * w32menu.c (pending_menu_activation): Remove since not
1220 (set_frame_menubar): Adjust user.
1221 * w32term.h (struct x_output): Drop outdated #if 0 code.

1224 Drop unused pending_menu_activation member.
1225 * xterm.h (struct x_output): Drop outdated #if 0 code.
1226 Use bitfields for explicit_parent, asked_for_visible,
1227 has_been_visible and net_wm_state_hidden_seen members.
1229 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1231 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1232 of a literal "/". (Bug#12955)
1233 (gl-stamp): Invoke fc.exe directly, not through cmd.

1238 * dired.c: Assume HAVE_DIRENT_H.
1239 (NAMLEN): Remove, replacing with ...
1240 (dirent_namelen): New function. All uses changed. Use the GNU macro
1241 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1242 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1243 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1244 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1246 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1247 * ndir.h: Rename to ../nt/inc/dirent.h.
1248 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1249 Do not include <dirent.h>; no longer needed.
1250 * w32.c: Include <dirent.h> rather than "ndir.h".
1252 2012-11-23 Chong Yidong <cyd@gnu.org>
1254 * xftfont.c (xftfont_open): Remove duplicate assignment.
1256 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1258 * alloc.c (Fgarbage_collect): Unblock input after clearing
1259 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1260 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1261 * msdos.c (IT_frame_up_to_date): Use it here...
1262 * w32term.c (w32_frame_up_to_date): ...here...
1263 * xterm.c (XTframe_up_to_date): ...and here...
1264 * nsterm.m (ns_frame_up_to_date): ...but not here.
1265 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1267 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1268 Do not check whether GC is in progress.
1270 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1272 * xdisp.c (window_buffer_changed): New function.
1273 (update_menu_bar, update_tool_bar): Use it to
1274 simplify large 'if' statements.
1275 (redisplay_internal): Generalize commonly used
1276 'tail' and 'frame' local variables.
1278 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1280 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1281 with Windows system header.
1283 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1285 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1286 * alloc.c: Assume unistd.h exists.
1287 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1288 * sysdep.c (get_current_dir_name): Assume getcwd exists.

1290 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1291 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1292 * w32.h (getcwd): Remove decl.
1294 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1296 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1297 Make it set selected_window as well.
1298 (update_tool_bar): Use it.
1300 2012-11-21 Ken Brown <kbrown@cornell.edu>
1302 * emacs.c (main): Set the G_SLICE environment variable for all
1303 Cygwin builds, not just GTK builds. See
1304 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1306 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1308 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1309 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1310 Define for the MSVC compiler.
1312 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1314 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1315 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1316 dostounix_filename. Prevents crashes down the road, because
1317 dostounix_filename assumes it gets a unibyte string.
1318 Reported by Michel de Ruiter <michel@sentient.nl>, see

1350 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1351 (syms_of_eval): Remove corresponding defsubr.
1352 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1354 2012-11-19 Daniel Colascione <dancol@dancol.org>
1356 * w32fns.c (Fx_file_dialog):
1357 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1358 cygwin_convert_file_name*.
1360 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1361 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1363 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1365 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1367 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1369 * w32select.c: Include w32common.h before w32term.h, so that
1370 windows.h gets included before w32term.h uses some of its
1371 features, see below.
1373 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1375 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

1379 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1381 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1382 (ns_select): Return at once if events are held (Bug#12834).
1384 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1386 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1387 Needed following 2012-10-20 change. (Bug#12902)
1389 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1391 * w32proc.c (waitpid): Remove unused label get_result.
1393 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1395 * makefile.w32-in (SYSWAIT_H): New macro.
1396 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1397 ($(BLD)/sysdep.$(O)): Update dependencies.
1399 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>

1402 * callproc.c (relocate_fd): Assume F_DUPFD.
1403 * emacs.c, term.c (O_RDWR): Remove.
1404 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1405 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1406 * nsterm.m: Assume <fcntl.h> exists.
1407 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1408 (create_pty, Fmake_network_process, server_accept_connection)
1409 (wait_reading_process_output, init_process_emacs):
1411 (wait_reading_process_output): Put in a special case for WINDOWSNT
1412 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1413 It's not clear this is needed, but it's a more-conservative change.
1414 (create_process): Assume FD_CLOEXEC.
1415 (create_process, create_pty): Assume O_NOCTTY.
1416 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1417 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1418 Omit if not DOS_NT, since F_GETFL is not defined there.
1419 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1420 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1422 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1423 lack it, since gnulib guarantees this.
1424 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1426 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1428 * w32.c (faccessat): Pretend that directories have the execute bit
1429 set. Emacs expects that, e.g., in files.el:cd-absolute.
1431 * w32proc.c (create_child): Don't clip the PID of the child
1432 process to fit into an Emacs integer, as this is no longer a
1434 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1435 reaping only the process specified by PID argument, if that is
1436 positive. Use PID instead of dead_child to know which process to
1437 reap. Wait for the child to die only if WNOHANG is not in
1439 (sys_select): Don't set dead_child.
1441 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1442 as it is no longer needed.
1444 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1446 (record_child_status_change): Remove the setting of
1447 record_at_most_one_child for the !WNOHANG case.
1449 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1451 Fix problems in ns port found by static checking.
1452 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1453 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1454 not to process group.
1455 (ns_select): Use emacs_write, not write, as that's more robust
1456 in the presence of signals.
1457 (fd_handler:): Check for read errors.
1459 2012-11-16 Glenn Morris <rgm@gnu.org>
1461 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1463 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1465 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1467 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1469 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1470 use the same value of thread handle.
1471 (start_timer_thread): If the timer thread exited (due to error),
1472 clean up by closing the two handles it used. Duplicate the caller
1473 thread's handle here, so it gets duplicated only once, when
1474 launching the timer thread. Set priority of the timer thread, not
1476 (getitimer): Don't duplicate the caller thread's handle here.
1479 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1481 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1484 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1486 Remove no-longer-used pty_max_bytes variable.
1487 * process.c (pty_max_bytes): Remove; unused.
1488 (send_process): Do not set it.
1490 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1492 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1493 Update dependencies.
1495 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1497 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1498 This follows up on the 2012-09-29 patch that removed indirection
1499 for the 'function' field. Reported by Sergey Vinokurov in
1500 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1502 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1504 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1505 different name, as the MS runtime does not have such a function,
1506 and probably never will.) All callers changed. Ignore DIRFD
1507 value if PATH is an absolute file name, to match Posix spec
1508 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1511 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1513 * xdisp.c (echo_area_display, redisplay_internal):
1514 Omit redundant check whether frame_garbaged is set.
1516 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1518 Use faccessat, not access, when checking file permissions (Bug#12632).
1519 This fixes a bug that has been present in Emacs since its creation.
1520 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1521 which must set some sort of record. (Torek's bug report was against
1522 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1523 same common flaw.) See Torek's Usenet posting
1524 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1525 Posted: Fri Apr 8 14:18:56 1983.
1526 * Makefile.in (LIB_EACCESS): New macro.
1528 * callproc.c (init_callproc):
1529 * charset.c (init_charset):
1530 * fileio.c (check_existing, check_executable, check_writable)
1532 * lread.c (openp, load_path_check):
1533 * process.c (allocate_pty):
1535 Use effective UID when checking permissions, not real UID.
1536 * callproc.c (init_callproc):
1537 * charset.c (init_charset):
1538 * lread.c (load_path_check, init_lread):
1539 Test whether directories are accessible, not merely whether they exist.
1540 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1541 * fileio.c (check_existing, check_executable, check_writable)
1543 Use symbolic names instead of integers for the flags, as they're
1545 (check_writable): New arg AMODE. All uses changed.
1546 Set errno on failure.
1547 (Ffile_readable_p): Use faccessat, not stat + open + close.
1548 (Ffile_writable_p): No need to call check_existing + check_writable.
1549 Just call check_writable and then look at errno. This saves a syscall.
1550 dir should never be nil; replace an unnecessary runtime check
1551 with an eassert. When checking the parent directory of a nonexistent
1552 file, check that the directory is searchable as well as writable, as
1553 we can't create files in unsearchable directories.
1554 (file_directory_p): New function, which uses 'stat' on most platforms
1555 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1556 (Ffile_directory_p, Fset_file_times): Use it.
1557 (file_accessible_directory_p): New function, which uses a single
1558 syscall for efficiency.
1559 (Ffile_accessible_directory_p): Use it.
1560 * xrdb.c (file_p): Use file_directory_p.
1561 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1562 * lread.c (openp): When opening a file, use fstat rather than
1563 stat, as that avoids a permissions race. When not opening a file,
1564 use file_directory_p rather than stat.
1565 (dir_warning): First arg is now a usage string, not a format.
1566 Use errno. All uses changed.
1567 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1568 that merely introduced a race.
1569 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1570 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1571 and similarly for the other O_* flags.
1572 * w32.c (sys_faccessat): Rename from sys_access and switch to
1573 faccessat's API. All uses changed.
1574 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1575 (magic_db): Rename from magic_file_p.
1576 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1577 char *, so that we don't have to test for file existence
1578 separately from opening the file for reading. This removes a race
1579 fixes a permission-checking problem, and simplifies the code.
1581 (file_p): Remove; no longer needed.
1583 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1585 Omit glyphs initialization at startup.
1586 * dispnew.c (glyphs_initialized_initially_p): Remove.
1587 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1588 (Fredraw_frame): Move actual code from here...
1589 (redraw_frame): ...to here. Add eassert. Adjust comment.
1590 (Fredraw_display): Use redraw_frame.
1591 * xdisp.c (clear_garbaged_frames): Likewise.
1593 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1595 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1596 passed to pint2str and pint2hrstr to be at most the size of the
1597 frame's decode_mode_spec_buffer. This avoids crashes with very
1598 large values of FIELD_WIDTH argument to decode_mode_spec.
1601 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1603 Fix a race with verify-visited-file-modtime (Bug#12863).
1604 Since at least 1991 Emacs has ignored an mtime difference of no
1605 more than one second, but my guess is that this was to work around
1606 file system bugs that were fixed long ago. Since the race is
1607 causing problems now, let's remove that code.
1608 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1609 whose time stamp is off by no more than a second. Insist that the
1610 file time stamps match exactly.
1612 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1614 * frame.h (struct frame): Convert external_tool_bar member to
1615 1-bit unsigned bitfield.
1616 * termhooks.h (struct terminal): Remove mouse_moved member since
1617 all users are long dead. Adjust comment on mouse_position_hook.
1619 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1621 Simplify by using FOR_EACH_FRAME here and there.
1622 * frame.c (next_frame, prev_frame, other_visible_frames)
1623 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1624 * w32term.c (x_window_to_scroll_bar): Likewise.
1625 * window.c (window_list): Likewise.
1626 * xdisp.c (x_consider_frame_title): Likewise.
1627 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1628 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1629 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1630 * xmenu.c (menubar_id_to_frame): Likewise.
1631 * xselect.c (frame_for_x_selection): Likewise.
1632 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1633 (x_window_to_menu_bar): Likewise.
1634 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1636 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1638 * data.c (Qdefalias_fset_function): Now static.
1640 Another tweak to vectorlike_header change.
1641 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1642 Remove, and replace all uses with ...
1643 (next_in_free_list, set_next_in_free_list):
1644 New functions, which respect C's aliasing rules better.
1646 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1648 * window.c (list4i): Rename from 'quad'. All uses changed.
1649 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1651 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1653 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1654 warning about mixing declarations and code in ISO C90.
1656 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1658 * window.c (Fsplit_window_internal): Set combination limit of
1659 new parent window to t iff Vwindow_combination_limit is t;
1660 fixing a regression introduced with the change from 2012-09-22.
1661 (Fset_window_combination_limit): Fix doc-string.
1663 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1665 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1666 amount when the scroll margins are too large. When scrolling
1667 backwards in the buffer, give up if cannot reach point or the
1668 scroll margin within a reasonable number of screen lines.
1669 Fixes point position in window under scroll-up/down-aggressively when
1670 point is positioned many lines beyond the window top/bottom.
1673 * ralloc.c (relinquish): If real_morecore fails to return memory
1674 to the system, don't crash; instead, leave the last heap
1675 unchanged and return. (Bug#12774)
1677 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1679 * lisp.h (AUTOLOADP): New macro.
1680 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1681 * data.c (Ffset): Remove special ad-advice-info handling.
1682 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1684 (Finteractive_form): Simplify.
1685 (Fquo): Don't insist on having at least 2 arguments.
1686 (Qdefalias_fset_function): New var.
1688 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1690 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1692 * nsfont.m (Qcondensed, Qexpanded): New variables.
1693 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1694 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1696 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1698 Fix recently introduced crash on MS-Windows (Bug#12839).
1699 * w32term.h (struct scroll_bar): Use convenient header.
1700 (SCROLL_BAR_VEC_SIZE): Remove.
1701 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1703 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1705 Tweak last vectorlike_header change.
1706 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1707 vectorlike object on the free list. This is introduced to avoid
1708 some (but not all) pointer casting and aliasing problems, see
1709 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1710 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1712 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1714 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1716 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1717 been removed, so remove them here also.
1719 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1721 * doc.c (Fdocumentation): Handle new property
1722 dynamic-docstring-function to replace the old ad-advice-info.
1724 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1726 * fns.c (Qeql, hashtest_eq): Now static.
1728 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1730 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1731 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1732 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
1733 * buffer.c (compare_overlays): Use XLI rather than XHASH.
1735 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1737 Use same hash function for hashfn_profiler as for hash_string etc.
1738 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1739 * lisp.h (sxhash_combine): New inline function, with the contents
1740 of the old SXHASH_COMBINE.
1741 * profiler.c (hashfn_profiler): Use it, instead of having a
1742 special hash function containing a comparison that always yields 1.
1744 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1746 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1747 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1748 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1751 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1753 * image.c (xpm_make_color_table_h): Fix compiler error because
1754 make_hash_table changed.
1756 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1758 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1760 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1762 Use ad-hoc comparison function for the profiler's hash-tables.
1763 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1764 (make_log): Use them.
1765 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1766 call Fequal any more.
1767 (Ffunction_equal): New function.
1768 (cmpfn_profiler, hashfn_profiler): New functions.
1769 (syms_of_profiler): Initialize them.
1770 * lisp.h (struct hash_table_test): New struct.

1775 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1776 (hash_lookup, hash_remove_from_table): Move assertion checking of
1777 hashfn result here. Check hash-equality before calling cmpfn.

1784 * print.c (print_object): Adjust to new hash-table struct.
1785 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
1787 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1789 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1790 value of w32-scroll-lock-modifier is neither nil nor one of the
1791 known key modifiers. (Bug#12806)
1793 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1795 Shrink struct vectorlike_header to the only size field.
1796 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1798 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1799 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1800 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1801 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1802 information from the vector header. Adjust comment.
1803 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
1804 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
1806 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
1807 (struct vectorlike_header): Remove next member. Adjust comment.

1810 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
1811 (sweep_string, lisp_malloc): Remove useless prototypes.
1812 (enum mem_type): Adjust comment.
1813 (NEXT_IN_FREE_LIST): New macro.
1814 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1815 (Fmake_bool_vector): Likewise.
1816 (struct large_vector): New type to represent allocation unit for
1817 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1818 (large_vectors): Change type to struct large_vector.
1819 (allocate_vector_from_block): Simplify.
1820 (PSEUDOVECTOR_NBYTES): Replace with...
1821 (vector_nbytes): ...new function. Adjust users.
1822 (sweep_vectors): Adjust processing of large vectors.
1823 (allocate_vectorlike): Likewise.
1824 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1825 Add easserts. Adjust XSETPVECTYPESIZE usage.
1826 (allocate_buffer): Use BUFFER_PVEC_INIT.
1827 (live_vector_p): Adjust to match large vector.
1828 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1829 * buffer.h (struct buffer): Add next member.
1830 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1832 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1833 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1834 (copy_hash_table): Adjust to match vector header change.
1835 * lread.c (defsubr): Use XSETPVECTYPE.
1836 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
1837 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
1838 (xvecsize): New command.
1840 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1842 * keyboard.c (event_to_kboard): Do not dereference
1843 frame_or_window field of SELECTION_REQUEST_EVENT
1844 and SELECTION_CLEAR_EVENT events (Bug#12814).
1845 * xterm.h (struct selection_input_event): Adjust comment.
1847 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1849 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1850 such as Scroll Lock, if the respective keys are treated as
1851 function keys, not as modifiers. This avoids destroying non-ASCII
1852 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1854 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1856 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1858 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1860 Restore some duplicate definitions (Bug#12814).
1861 This undoes part of the 2012-11-03 changes. Some people build
1862 with plain -g rather than with -g3, and they need the duplicate
1863 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1864 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1865 Define as macros, as well as as enums or as constants.
1867 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1869 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1870 to keypad keys (Bug#12816).
1872 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1874 Minor adjustments of recently-changed frame functions.
1875 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1876 known to be a frame (we're in the FRAMEP branch).
1877 * lisp.h (Qframep): Remove decl. frame.h declares this.
1878 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1879 since they're meant for Lisp fixnum values.
1881 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1883 * window.c (Fwindow_combination_limit): Revert to the only
1884 required argument and adjust docstring as suggested in
1885 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1886 by Martin Rudalics <rudalics@gmx.at>.
1888 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1890 Widely used frame validity and checking functions.
1891 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.

1902 (frame_buffer_list, frame_buffer_predicate): Remove.
1903 * lisp.h (frame_buffer_predicate): Remove prototype.
1904 * buffer.c (Fother_buffer): Use decode_any_frame.
1905 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1906 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1907 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1908 (Fclose_font, Ffont_info): Use decode_live_frame.

1923 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1925 * window.c (quad): New function.
1926 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1927 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1928 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)

1930 (Fwindow_fringes): Use list3.
1931 (Fwindow_scroll_bars): Use list4.
1932 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1933 (Fwindow_combination_limit): Allow zero number of arguments.
1935 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1937 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1939 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1940 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1941 file descriptor 2 for standard error. (Bug#12805)
1943 2012-11-05 Chong Yidong <cyd@gnu.org>
1945 * process.c (wait_reading_process_output): Revert previous change.
1947 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1949 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1950 This removes code that has been obsolete since around 1990.
1951 * callproc.c (Fcall_process):
1953 * process.c (create_process):
1954 * term.c (dissociate_if_controlling_tty):
1955 Assume setsid exists.
1956 * callproc.c (child_setup): Assume setpgid exists and behaves as
1957 per POSIX.1-1988 or later.
1958 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1959 * emacs.c (shut_down_emacs):
1960 * sysdep.c (sys_suspend, init_foreground_group):
1961 Assume getpgrp behaves as per POSIX.1-1998 or later.
1962 * msdos.c (setpgrp): Remove.
1963 (tcgetpgrp, setpgid, setsid): New functions.
1964 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1965 * term.c (no_controlling_tty): Remove; unused.
1966 * w32proc.c (setpgrp): Remove.
1967 (setsid, tcgetpgrp): New functions.
1969 Simplify by assuming __fpending.
1970 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1971 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1972 Do not assume that __fpending's result fits in int.
1974 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1976 Remove EMACS_OUTQSIZE+sleep hack.
1977 * dispnew.c (update_frame_1): Remove hack for terminals slower
1978 than 2400 bps, which throttled Emacs by having it sleep.
1979 This code hasn't worked since at least 2007, when the multi-tty stuff
1980 was added, and anyway those old terminals are long dead.
1981 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1982 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1984 Fix data-loss with --version (Bug#9574).
1985 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1986 as we can't assume that emacs_strerror is initialized, and strerror
1987 is good enough here.
1988 (main): Invoke atexit earlier, to catch earlier instances of
1989 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1991 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1993 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1994 (keyDown): Remap keypad keys to X11 virtual key codes.
1996 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1998 Fix data-loss with --batch (Bug#9574).
1999 * emacs.c: Include <close-stream.h>.
2000 (close_output_streams): New function.
2001 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2002 and handles errors appropriately.
2003 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2006 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2007 The symptom is a diagnostic "GLib-WARNING **: In call to
2008 g_spawn_sync(), exit status of a child process was requested but
2009 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2010 waitpid(), so exit status can't be returned." The diagnostic
2011 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2012 The real bug is a race condition between Emacs and glib: Emacs
2013 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2014 so that glib can't find it. Work around the bug by invoking
2015 waitpid only on subprocesses that Emacs itself creates.
2016 * process.c (create_process, record_child_status_change):
2017 Don't use special value -1 in pid field, as the caller now must
2018 know the pid rather than having the callee infer it.
2019 The inference was sometimes incorrect anyway, due to another race.
2020 (create_process): Set new 'alive' member if child is created.
2021 (process_status_retrieved): New function.
2022 (record_child_status_change): Use it.
2023 Accept negative 1st argument, which means to wait for the
2024 processes that Emacs already knows about. Move special-case code
2025 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2026 processes that have already been waited for, by testing and
2027 clearing new 'alive' member.
2028 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2029 now does this internally.
2030 (handle_child_signal): Let record_child_status_change do all
2031 the work, since we do not want to reap all exited child processes,
2032 only the child processes that Emacs itself created.
2033 * process.h (Lisp_Process): New boolean member 'alive'.
2035 Omit duplicate definitions no longer needed with gcc -g3.
2036 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2037 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2038 Define only as macros. There's no longer any need to also define
2039 these symbols as enums or as constants, since we now assume
2040 gcc -g3 when debugging.
2042 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2044 * lisp.mk: Adjust comments to the fact that term/internal is now
2045 loaded from loadup.el.
2047 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2048 (msdos_fatal_signal): New function.
2049 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2052 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2053 for GCC versions before 4.
2054 (emacs_raise): Define to call msdos_fatal_signal.
2056 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2057 iterator when starting in the middle of a display or overlay
2060 2012-11-03 Chong Yidong <cyd@gnu.org>
2062 * process.c (wait_reading_process_output): Clean up the last
2065 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2067 * process.c (wait_reading_process_output): Avoid a race condition
2068 with SIGIO delivery (Bug#11536).
2070 2012-11-03 Chong Yidong <cyd@gnu.org>
2072 * buffer.c (cursor_type): Untabify docstring.
2074 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2076 * frame.h (struct frame): Drop can_have_scroll_bars member
2077 which is meaningless for a long time. Adjust comments.
2078 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2079 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2081 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2083 * window.c (decode_next_window_args): Update window arg after
2084 calling decode_live_window and so fix crash reported at
2085 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2086 by Juanma Barranquero <lekktu@gmail.com>.
2087 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2088 * font.c (Ffont_at): Likewise.
2090 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2092 * widget.c (resize_cb): New function.
2093 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2094 (EmacsFrameResize): Check if all is up to date before changing frame
2097 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2099 Implement backtrace output for fatal errors on MS-Windows.
2100 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2101 (BACKTRACE_LIMIT_MAX): New macro.
2102 (w32_backtrace): New function.
2103 (emacs_abort): Use w32_backtrace when the user chooses not to
2104 attach a debugger. Update the text of the abort dialog.
2106 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2108 Window-related stuff cleanup here and there.
2109 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2110 Use decode_any_window.
2111 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2112 * xdisp.c (Fformat_mode_line): Likewise.
2113 * font.c (Ffont_at): Use decode_live_window.
2114 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2115 * window.c (decode_next_window_args): Likewise.
2116 (decode_any_window): Remove static.
2117 * window.h (decode_any_window): Add prototype.
2118 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2119 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2122 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2124 Remove pad from struct input_event.
2125 * termhooks.h (struct input_event): Remove padding field.
2127 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2128 member is never cons for a long time. Adjust comment.
2129 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2130 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2131 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2132 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2134 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2136 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2138 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2140 Fix crash when using Emacs as commit editor for git (Bug#12697).
2141 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2142 and it is configured in conf_post.h.
2143 (Fcall_process): Don't invoke both setsid and setpgid; the former
2144 is enough, if it exists.
2145 * callproc.c (Fcall_process, child_setup):
2146 * process.c (create_process): Use setpgid.
2147 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2149 * dispnew.c (init_display): Initialize the foreground group
2150 if we are running a tty display.
2151 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2152 * lisp.h (init_foreground_group): New decl.
2153 * sysdep.c (inherited_pgroup): New static var.
2154 (init_foreground_group, tcsetpgrp_without_stopping)
2155 (narrow_foreground_group, widen_foreground_group): New functions.
2156 (init_sys_modes): Narrow foreground group.
2157 (reset_sys_modes): Widen foreground group.
2159 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2161 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2163 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2165 * minibuf.c (read_minibuf): Restore current buffer since
2166 choose_minibuf_frame calling Fset_frame_selected_window may
2167 change it (Bug#12766).
2169 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2171 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2173 2012-10-30 Kenichi Handa <handa@gnu.org>
2175 * font.c (Ffont_at): If WINDOW is specified and it is not
2176 displaying the current buffer, signal an error.
2178 2012-10-29 Daniel Colascione <dancol@dancol.org>
2180 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2181 In preparation for fixing bug#12739, move these functions from
2184 * coding.h, coding.c: ... to here, and compile them only when
2185 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2186 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2188 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2190 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2191 (timer_loop, getitimer, setitimer): Use it instead of
2192 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2194 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2197 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2199 * nsterm.m (NO_APPDEFINED_DATA): New define.
2200 (last_appdefined_event_data): New variable
2201 (last_appdefined_event): Remove.
2202 (ns_select): Initialize t from last_appdefined_event_data instead
2203 of [last_appdefined_event data1].
2204 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2205 remove last_appdefined_event (Bug#12698).
2207 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2209 * frame.c (x_set_font): Catch internal error.
2211 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2213 Avoid overflow in w32 implementation of interval timers.
2214 When possible, for ITIMER_PROF count only times the main thread
2216 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2217 'volatile ULONGLONG' types. All the other data which was
2218 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2219 (GetThreadTimes_Proc): New typedef.
2220 (w32_get_timer_time): New function, returns a suitable time value
2222 (timer_loop): Enter critical section when accessing ULONGLONG
2223 values of the itimer_data struct, as these accesses are no longer
2224 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2225 Remove unused variable.
2226 (init_timers): Initialize s_pfn_Get_Thread_Times.
2227 (start_timer_thread): Don't assign itimer->caller_thread here.
2228 (getitimer): Assign itimer->caller_thread here.
2229 (setitimer): Always call getitimer to get the value of ticks_now.
2230 (sys_spawnve): Avoid compiler warning about format mismatch.
2232 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2234 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2235 mouse movement events if the menu bar is active. This avoids
2236 producing a busy "hour-glass" cursor by Windows if the mouse
2237 pointer is positioned over a tooltip shown for some menu item.
2239 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2241 Don't assume process IDs fit in int.
2242 * emacs.c (shut_down_emacs) [!DOS_NT]:
2243 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2244 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2245 Use pid_t, not int, to store process IDs, as 'int'
2246 is not wide enough on a few platforms (e.g., AIX and IRIX).
2248 2012-10-23 Kenichi Handa <handa@gnu.org>
2250 The following change is to make face-font-rescale-alist work
2251 correctly for non-ASCII fonts.
2253 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2254 (font_open_for_lface): Handle Vface_font_rescale_alist.
2256 2012-10-23 Chong Yidong <cyd@gnu.org>
2258 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2260 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2262 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2264 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2266 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2269 2012-10-21 Glenn Morris <rgm@gnu.org>
2271 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2273 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2275 Port to OpenBSD 5.1.
2276 * frame.c (Fmouse_position, Fmouse_pixel_position):
2277 * xdisp.c (produce_stretch_glyph):
2278 Declare local vars only when they're needed.
2279 This is clearer and avoids a warning on OpenBSD about unused vars.
2280 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2281 This is safer, and avoids OpenBSD warnings about unused vars.
2282 * keyboard.c (record_menu_key): Remove unnecessary decl.
2283 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2284 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2285 as our definition clashes with OpenBSD's.
2286 * xfaces.c (load_face_colors, check_lface_attrs)
2287 (get_lface_attributes_no_remap, get_lface_attributes)
2288 (lface_fully_specified_p, x_supports_face_attributes_p)
2289 (tty_supports_face_attributes_p, face_fontset, realize_face)
2290 (realize_x_face, realize_tty_face):
2291 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2292 merely Lisp_Object *. This is more informative and avoids
2293 a warning on OpenBSD about accessing beyond an object's size.
2295 2012-10-20 Chong Yidong <cyd@gnu.org>
2297 * lread.c (Fload): Doc fix (Bug#12592).
2299 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2301 * font.c (Ffont_at): Fix previous change.
2303 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2305 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2306 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2309 * alloc.c (NSTATICS): Decrease to 0x800.
2311 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
2313 * fns.c (Fnreverse): Include the problem element when signaling an
2316 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2318 * nsterm.m (ns_select): Check writefds before call to
2319 FD_ISSET (Bug#12668).
2321 2012-10-18 Daniel Colascione <dancol@dancol.org>
2323 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2324 (staticpro): If we run out of staticpro slots, die with an
2325 informative error instead of just calling emacs_abort.
2327 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2329 Fix two flaws reported by Dmitry Antipov.
2330 * window.c (Ftemp_output_buffer_show): Remove.
2331 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
2332 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
2334 2012-10-17 Eli Zaretskii <eliz@gnu.org>
2336 * makefile.w32-in ($(BLD)/w32.$(O)):
2337 ($(BLD)/vm-limit.$(O)):
2339 ($(BLD)/unexw32.$(O)):
2340 ($(BLD)/fileio.$(O)):
2341 ($(BLD)/dispnew.$(O)): Update dependencies.

2584 since unsigned is guaranteed to have that behavior and signed is not.
2585 (read_char): Use ptrdiff_t for string length.
2586 (get_input_pending): Remove first argument, since it was always
2587 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2588 and behave as if it had that value. Return new value of
2589 input_pending. All callers changed.
2590 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2591 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

2594 All callers changed.

2620 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2622 * commands.h (immediate_quit): Remove duplicate decl.

2634 match what GetLastError returns. Explain why the function is
2637 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2638 'is_tooltip_frame', to avoid confusion with its global namesake.
2640 2012-10-08 Daniel Colascione <dancol@dancol.org>
2642 * xdisp.c (start_hourglass): Call w32_note_current_window when
2643 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2644 build that caused Emacs to display the hourglass cursor forever.
2646 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2647 which is broken under remote desktop, calculate the number of
2648 colors available for a display based on the display's number of
2649 planes and number of bits per pixel per plane. (bug#10397).
2651 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2653 * nsfont.m (Vfonts_in_cache): New variable.
2654 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2655 are used. Add cached fonts to Vfonts_in_cache.
2656 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2658 2012-10-08 Juanma Barranquero <lekktu@gmail.com>

2680 ($(BLD)/w32proc.$(O)): Add w32common.h.
2682 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now

2686 2012-10-08 Daniel Colascione <dancol@dancol.org>
2688 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2689 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2690 accidental message numbering hole. Change other messages to

2708 Remove duplicate definitions.
2710 * w32fns.c: Include w32common.h; include w32heap.h only in
2713 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2714 Use `report_file_error' instead of `error' in order to better
2715 inform users of what went wrong. Increase NTGUI_UNICODE file
2716 dialog box file name length to 32k, the maximum allowed by the NT
2719 * w32common.h: New file.
2720 (ROUND_UP, ROUND_DOWN, get_page_size)
2721 (get_allocation_unit, get_processor_type, get_w32_major_version)

2724 (OS_NT, os_subtype, cache_system_info): Move here.
2726 * unexw32.c, unexcw.c: Include w32common.h.
2728 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2729 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2730 to call syms_of_w32select.
2732 * cygw32.h: Remove obsolete EXFUN declarations.
2734 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

2746 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2748 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2751 2012-10-08 Daniel Colascione <dancol@dancol.org>
2753 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2754 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2755 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,

2758 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2759 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2760 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2761 now a supported configuration.
2763 * Makefile.in: consolidate image variables into LIBIMAGE; add
2764 W32_OBJ and W32_LIBS. Compile new files.
2767 (_DebPrint) declare tracing facility for W32 debugging. We need
2768 to unify tracing later.
2770 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2771 unconditional use of W32 Unicode functions. Cygwin runs only on
2772 100% Unicode operating systems.
2774 * cygw32.c: New file. Define Cygwin-specific facilities.
2775 (Fcygwin_convert_path_to_windows)
2776 (Fcygwin_convert_path_from_windows): New user functions for
2777 accessing Cygwin path-munging routines.
2779 * cygw32.h: New file.
2780 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2781 UTF-16LE strings temporarily inside non-Lisp-visible string
2784 (w32_strerror): Just what it says on the tin.
2786 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2787 also run for Cygwin; both systems have the same problem with using
2788 GUI facilities in a forked child. Also call syms_of_cygw32,
2789 syms_of_w32select in correct places.
2791 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2792 needs fork-then-exec for daemon launching.
2794 * font.h: Include frame.h.
2796 * image.c: Use the image library cache machinery only when we're
2797 compiling for native WINDOWSNT; Cygwin can use shared libraries
2798 like any other Unixlike system.
2800 * keyboard.c: Clarify a comment regarding the input loop.
2802 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2803 functions directly instead of trying to detect at runtime that our
2804 host operating system supports them. We make this change for two
2805 reasons: Cygwin lacks support for the multibyte character
2806 conversion functions used by the legacy menu code, and Cygwin
2807 never needs to rely on non-Unicode APIs.
2809 * unexw32.c (hinst): Declare extern.
2811 * w32.c: Change header order;
2812 (w32_strerror): Move to w32fns.c because we need it for
2813 non-WINDOWSNT builds.
2815 * w32.h: Add #error macro to make sure we don't include w32.h for
2816 Cygwin builds. Remove w32select declarations.
2818 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2819 w32fns.c. w32console.c is WINDOWSNT-only.
2821 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2822 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2824 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2825 (w32_major_version, w32_minor_version, w32_build_number)
2826 (os_subtype, sound_type): Define here
2827 (w32_defined_color): Make color parameter const for consistency
2828 with other _defined_color functions.
2829 (w32_createwindow): Unconditionally call w32_init_class instead of
2830 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2831 through the code is complex and unnecessary because class
2832 registration is practically free.
2833 (w32_name_of_message): New EMACSDEBUG-only function.
2834 (Fset_message_beep): Move here
2835 (Fx_open_connection): Require that the display name for Windows be
2836 "w32" for consistency, emacsclient disambiguation, and maybe, one
2837 day, multi-window-system support.
2838 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2839 Cygwin files for W32 GUI facilities, since these clearly don't
2840 expect Cygwin names.
2841 (_DebPrint): Define.
2842 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2843 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2844 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2845 (w32_last_error): Remove.
2847 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2849 * w32heap.c (syspage_mask): Declare here.
2850 (cache_system_info): Remove.
2852 * w32inevt.c (faked_key): Define globally, not statically.
2853 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2854 (w32_console_toggle_lock_key): Move to w32fns.c.
2856 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2858 * w32proc.c (_DebPrint): Move to w32fns.c.
2859 * w32select.c: Include string.h, stdio.h for Cygwin.
2860 * w32select.h: New File.
2862 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2864 (w32_message_fd): New variable. Under Cygwin, holds the file
2865 descriptor the system used to tell us about pending thread
2868 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2869 that prevented compilation under non-WINDOWSNT systems.
2871 (w32_initialize): Open /dev/windows and assign it to
2872 w32_message_fd. Provide w32 feature.
2874 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2875 (WM_EMACS_INPUT_READY): add.
2876 (prepend_msg, w32_message_fd): Declare globally.
2879 (keyboard_handle): Use only when WINDOWSNT.
2880 (notify_msg_ready): New function. Posts a message to the main
2881 thread's message queue under CYGWIN, which wakes up the main
2882 thread from select(2) by making the /dev/windows file descriptor
2883 ready. Under WINDOWSNT, it sets an event the same way the old
2886 (post, prepend_msg): Actually call notify_msg_ready instead of
2887 setting the input event directly.
2889 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2891 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2892 but it still has blocs in it, don't return it to the system,
2893 instead of aborting. (Bug#12402)
2895 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2897 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2899 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2900 MAC_OS_X_VERSION_10_6.
2901 (syms_of_nsterm): Remove comment about Panther and above for
2903 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

2905 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2907 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2908 MAC_OS_X_VERSION_10_4.
2910 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2911 MAC_OS_X_VERSION_10_2.
2913 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2915 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2916 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2918 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2919 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2920 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2921 Remove ns_in_resize check.
2922 (ns_clear_frame_area): Remove resize handle code.
2924 * nsfns.m (ns_in_resize): Remove.
2925 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2926 Remove ns_in_resize check.
2928 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2930 Improve sys_siglist detection.
2931 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2932 defined as a macro, as is done in Solaris.
2933 (sys_siglist_entries): New macro.
2934 (save_strsignal): Use it.
2935 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2936 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2938 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2940 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2941 fullscreen/Fullscreen.
2943 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2944 tobar_height is new.
2946 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2947 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2948 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2949 (windowDidResize:): Check for correct window if old style fullscreen.
2950 Capitalize word in comment. Remove incorrect comment.
2951 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2952 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2953 error in drawing background.
2954 (toggleFullScreen:): Remove comment. Rearrange calls.
2955 Set toolbar values to zero, save old height in tobar_height.
2956 Restore tool bar height when leaving fullscreen.
2957 (canBecomeMainWindow): New function.
2959 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2961 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2963 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2965 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2967 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2968 that time stamps of directories could also be changed.
2969 Don't request the too broad GENERIC_WRITE, only the more restrictive
2970 FILE_WRITE_ATTRIBUTES access rights.
2972 * fileio.c (Fset_file_times): Special-case ignoring errors for
2973 directories only on MSDOS, not on MS-Windows.
2975 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2977 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2979 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2981 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2982 see whether CreateFile failed.
2984 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2986 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2987 to avoid similar races.
2988 * keyboard.c (pending_signals): Now bool, not int.
2990 Port timers to OpenBSD, plus check for timer failures.
2991 OpenBSD problem reported by Han Boetes.
2992 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2994 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2995 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2996 like OpenBSD, which has timer_settime but does not declare it.
2997 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2998 whether to use itimerspec-related primitives. All uses of
2999 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3001 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3003 * profiler.c (handle_profiler_signal): Fix a malloc race
3004 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3006 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3008 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3010 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3012 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3013 consistent with the change in return value of 'safe_strsignal'.
3015 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3017 Prefer plain 'static' to 'static inline' (Bug#12541).
3018 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3019 (bidi_set_sor_type, bidi_push_embedding_level)
3020 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3021 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3022 (bidi_cache_search, bidi_cache_ensure_space)
3023 (bidi_cache_iterator_state, bidi_cache_find)
3024 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3025 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3026 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3027 Now 'static', not 'static inline'.
3029 Count overruns when profiling; change units to ns.
3030 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3031 Give extra weight to samples after overruns, to attempt to count
3032 the time more accurately.
3033 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3034 the underlying primitives nominally do ns.
3035 (Fprofiler_cpu_start): Document the change. Mention that
3036 the sampling intervals are only approximate.
3038 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3040 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3042 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3043 case for the special 0 coding-system.
3045 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3046 (Fmake_overlay): Remove redundant tests.
3047 (fix_start_end_in_overlays): Remove redundant recentering.
3049 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3051 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3052 Update dependencies.
3054 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3056 Fix a malloc race condition involving strsignal.
3057 A signal can arrive in the middle of a malloc, and Emacs's signal
3058 handler can invoke strsignal, which can invoke malloc, which is
3059 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3060 Fix it by altering the signal handler so that it does not invoke
3062 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3063 * process.c (status_message): Use const pointer, in case strsignal
3064 is #defined to safe_strsignal.
3065 * sysdep.c (sys_siglist, init_signals): Always define and
3066 initialize a substitute sys_siglist if the system does not define
3067 one, even if HAVE_STRSIGNAL.
3068 (safe_strsignal): Rename from strsignal. Always define,
3069 using sys_siglist. Return a const pointer.
3070 * syssignal.h (safe_strsignal): New decl.
3071 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3073 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3075 * w32proc.c (timer_loop): Fix code that waits for timer
3076 expiration, to avoid high CPU usage.
3078 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3080 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3081 (sweep_weak_table): Remove redundant prototypes.
3083 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3085 * emacs.c: Move the inclusion of TERM_HEADER after including
3086 windows.h on WINDOWSNT. This avoids compilation problems with
3089 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3091 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3092 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3093 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3094 as the previous version used 'void *'.
3096 * ralloc.c (ROUNDUP): Fix last change.
3097 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3100 * w32proc.c <disable_itimers>: New static flag.
3101 (init_timers): Initialize it to zero, after creating the critical
3102 sections used by the timer threads.
3103 (term_timers): Set to 1 before deleting the critical sections.
3104 (getitimer, setitimer): If disable_itimers is non-zero, return an
3105 error indication without doing anything. Reported by Fabrice
3106 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3107 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3109 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3112 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3113 term_ntproc after all the other bookkeeping, to get timers working
3114 as long as possible.
3116 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3118 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3119 Suggested by Juri Linkov in
3120 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3122 Prefer plain 'static' to 'static inline' (Bug#12541).
3123 With static functions, modern compilers inline pretty well by
3124 themselves; advice from programmers often hurts as much as it helps.
3125 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3126 this change shrinks the text size of the Emacs executable by 1.1%
3127 without affecting CPU significantly in my benchmark.
3128 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
3129 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
3130 (mark_maybe_object, mark_maybe_pointer, bounded_number):

3203 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
3204 Now 'static', not 'static inline'.
3207 (bidi_copy_it): Do the whole copy with a single memcpy.
3208 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3210 Revert the FOLLOW-SYMLINKS change for file-attributes.
3211 Doing it right would require several changes to Tramp, and there's
3212 not enough time to get that tested before the freeze today.
3213 * dired.c (directory_files_internal, Ffile_attributes):
3216 * frame.c (x_report_frame_params): Port better to wider ints.
3217 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3218 or that pointers can be printed in 15 decimal digits.
3219 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
3221 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>

3240 * w32heap.c (RVA_TO_PTR, allocate_heap, sbrk, init_heap)
3241 (round_heap): Use DWORD_PTR, ptrdiff_t and size_t instead of
3242 DWORD, long, and unsigned long, for compatibility with x64.

3250 * w32.c (init_environment, get_emacs_configuration): Support AMD64
3252 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
3253 compatibility with x64.
3255 * vm-limit.c (lim_data): Now size_t.
3256 (check_memory_limits): Adjust prototypes of real_morecore and
3257 __morecore to receive argument of type ptrdiff_t. Use size_t for
3258 five_percent and data_size.
3260 * unexw32.c: Use DWORD_PTR instead of DWORD for file-scope

3400 Suggested by Eli Zaretskii in
3401 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
3403 2012-09-30 Eli Zaretskii <eliz@gnu.org>
3405 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if

3410 Profiler improvements: more-accurate timers, overflow checks.
3411 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3412 signal.h, setjmp.h. Include systime.h instead.

3420 All uses changed to store the new value.
3421 (handle_profiler_signal): Rename from sigprof_handler_1,
3422 for consistency with other handlers. Do not check whether
3423 cpu_log is a hash-table if garbage collecting, since it
3424 doesn't matter in that case.

3426 for consistency with other handlers.
3427 (setup_cpu_timer): New function, with much of what used to be in
3428 Fprofiler_cpu_start. Check for out-of-range argument.
3429 Prefer timer_settime if available, and prefer
3430 thread cputime clocks, then process cputime clocks, then
3431 monotonic clocks, to the old realtime clock. Use make_timeval
3432 to round more-correctly when falling back to setitimer.
3433 (Fprofiler_cpu_start): Use it.
3434 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3435 Don't assume that passing NULL as the 2nd argument of setitimer

3438 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3439 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3440 non-fatal signal handlers. Ignore SIGPROF on startup.
3441 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3442 in profiler.c, since sysdep.c now uses it.
3444 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

3500 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3501 Since this stuff is now private to charset.c, there's no need for
3502 a public macro and no need to inline by hand.

3576 (sys_kill): Improve commentary.
3578 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3579 consistency with a signature of a signal handler. All callers
3581 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3582 install term_ntproc as a signal handler for SIGABRT, as that
3583 should be done by the dumped Emacs.

3702 ($(BLD)/w32xfns.$(O)): Update dependencies.
3704 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3706 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3707 fatal_error_backtrace.
3709 * w32proc.c (sys_kill): Undo last change: don't do anything when
3710 invoked to deliver SIGABRT to our own process. This is now
3711 handled by emacs_raise.
3713 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3715 * w32term.c (w32_read_socket): Remove leftover reference to
3716 interrupt_input_pending.
3718 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3720 Do not use SA_NODEFER.
3721 Problem reported by Dani Moncayo in
3722 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3724 * sysdep.c (emacs_abort): Do not reset signal handler.
3725 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3726 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3727 wanted even on POSIXish hosts, and it doesn't work on Windows.
3729 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3731 * xterm.c (x_term_init): Call fixup_locale before and after calling
3732 gtk_init (Bug#12392).
3734 2012-09-23 Chong Yidong <cyd@gnu.org>
3736 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3737 Vdynamic_library_alist.
3739 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3740 (Fgnutls_available_p): Caller changed.
3742 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3743 (Flibxml_parse_xml_region): Likewise.
3745 * dispextern.h (struct image_type): Remove arg from init function.
3747 * image.c (Finit_image_library, lookup_image_type)
3748 (define_image_type): Remove now-unneeded second arg.
3749 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3750 (init_tiff_functions, init_gif_functions, init_svg_functions):
3751 Arglist and w32_delayed_load calling convention changed.
3752 (gs_type): Remove init_gs_functions; there is no such function.
3753 (valid_image_p, make_image): Fix caller to lookup_image_type.
3755 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3757 Simplify and avoid signal-handling races (Bug#12471).
3759 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3760 Avoid recursive loop if there's a fatal error in the function itself.
3761 * atimer.c (pending_atimers):
3762 * blockinput.h: Don't include "atimer.h"; no longer needed.
3763 (interrupt_input_pending): Remove. All uses removed.
3764 pending_signals now counts both atimers and ordinary interrupts.
3765 This is less racy than having three separate pending-signal flags.
3766 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3768 Rename from their upper-case counterparts BLOCK_INPUT,
3769 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3770 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3771 This makes it easier to access volatile variables more accurately.
3772 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3773 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3774 that's more reliable if the code is buggy and sets
3775 interrupt_input_blocked to a negative value. All uses changed.
3776 * atimer.c (deliver_alarm_signal):
3777 Remove. No need to deliver this to the parent; any thread can
3778 handle this signal now. All uses replaced by underlying handler.
3779 * atimer.c (turn_on_atimers):
3780 * dispnew.c (handle_window_change_signal):
3781 * emacs.c (handle_danger_signal):
3782 * keyboard.c (kbd_buffer_get_event):
3783 Don't reestablish signal handler; not needed with sigaction.
3784 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3786 Rework to avoid unnecessary accesses to volatile variables.
3787 (UNBLOCK_INPUT_TO): Now a function.
3788 (totally_unblock_input, unblock_input): New decls.
3789 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3790 (init_data): Remove. Necessary stuff now done in init_signal.
3791 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3792 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3793 (fatal_error_code): Remove; no longer needed.
3794 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3795 it doesn't always backtrace. All uses changed. No need to reset
3796 signal to default, since sigaction and/or die does that for us now.
3797 Use emacs_raise (FOO), not kill (getpid (), FOO).
3798 (main): Check more-accurately whether we're dumping.
3799 Move fatal-error setup to sysdep.c
3800 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3801 * gtkutil.c (xg_get_file_name, xg_get_font):
3802 Remove no-longer-needed signal-mask manipulation.
3803 * keyboard.c, process.c (POLL_FOR_INPUT):
3804 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3805 * keyboard.c (read_avail_input): Remove.
3806 All uses replaced by gobble_input.
3807 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3808 (kbd_buffer_store_event_hold, gobble_input):
3809 (record_asynch_buffer_change) [USABLE_SIGIO]:
3810 (store_user_signal_events):
3811 No need to mess with signal mask.
3812 (gobble_input): If blocking input and there are terminals, simply
3813 set pending_signals to 1 and return. All hooks changed to not
3814 worry about whether input is blocked.
3815 (process_pending_signals): Clear pending_signals before processing
3816 them, in case a signal comes in while we're processing.
3817 By convention callers now test pending_signals before calling us.
3818 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3819 New functions, to support changes to blockinput.h.
3820 (handle_input_available_signal): Now extern.
3821 (reinvoke_input_signal): Remove. All uses replaced by
3823 (quit_count): Now volatile, since a signal handler uses it.
3824 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3825 All callers changed. Block SIGINT only if not already blocked.
3826 Clear sigmask reliably, even if Fsignal returns, which it can.
3827 Omit unnecessary accesses to volatile var.
3828 (quit_throw_to_read_char): No need to restore sigmask.
3829 * keyboard.c (gobble_input, handle_user_signal):
3830 * process.c (wait_reading_process_output):
3831 Call signal-handling code rather than killing ourselves.
3832 * lisp.h: Include <float.h>, for...
3833 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3834 (pending_signals): Now volatile.
3835 (syms_of_data): Now const if IEEE floating point.
3836 (handle_input_available_signal) [USABLE_SIGIO]:
3837 (terminate_due_to_signal, record_child_status_change): New decls.
3838 * process.c (create_process): Avoid disaster if memory is exhausted
3839 while we're processing a vfork, by tightening the critical section
3841 (send_process_frame, process_sent_to, handle_pipe_signal)
3842 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3844 (send_process): No need for setjmp/longjmp any more, since the
3845 SIGPIPE stuff is now gone. Instead, report an error if errno
3847 (record_child_status_change): Now extern. PID and W are now args.
3848 Return void, not bool. All callers changed.
3849 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3850 Remove. All uses removed. This bug should be fixed now in a
3852 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3853 and record the child status change directly. This avoids the
3854 need to futz with the signal mask.
3855 (process_fatal_action): Move here from emacs.c.
3856 (emacs_sigaction_flags): New function, containing
3857 much of what used to be in emacs_sigaction_init.
3858 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3859 caught by emacs, to make races less likely.
3860 (deliver_process_signal): Rename from handle_on_main_thread.
3862 (BACKTRACE_LIMIT_MAX): Now at top level.
3863 (thread_backtrace_buffer, threadback_backtrace_pointers):
3865 (deliver_thread_signal, deliver_fatal_thread_signal):
3866 New functions, for more-accurate delivery of thread-specific signals.
3867 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3868 (deliver_arith_signal): Handle in this thread, not
3869 in the main thread, since it's triggered by this thread.
3870 (maybe_fatal_sig): New function.
3871 (init_signals): New arg DUMPING so that we can be more accurate
3872 about whether we're dumping. Caller changed.
3873 Treat thread-specific signals differently from process-general signals.
3874 Block all signals while handling fatal error; that's safer.
3875 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3877 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3878 Ignore SIGPIPE unless batch.
3879 (emacs_backtrace): Output backtrace for the appropriate thread,
3880 which is not necessarily the main thread.
3881 * syssignal.h: Include <stdbool.h>.
3882 (emacs_raise): New macro.
3883 * xterm.c (x_connection_signal): Remove; no longer needed
3884 now that we use sigaction.
3885 (x_connection_closed): No need to mess with sigmask now.
3886 (x_initialize): No need to reset SIGPIPE handler here, since
3887 init_signals does this for us now.
3889 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3891 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3892 background rect may be larger (Bug#12245).
3894 2012-09-23 Chong Yidong <cyd@gnu.org>
3896 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3898 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3900 * .gdbinit: Just stop at fatal_error_backtrace.
3901 See Stefan Monnier's request in
3902 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3903 Remove no-longer-used query of system type.
3905 2012-09-22 Chong Yidong <cyd@gnu.org>
3907 * search.c (Freplace_match): Doc fix (Bug#12325).
3909 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3911 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3912 (Fline_end_position): Doc fix.
3914 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3916 2012-09-22 Chong Yidong <cyd@gnu.org>
3918 * dispextern.h (struct image_type): Add new slot, storing a type
3919 initialization function.
3921 * image.c (define_image_type): Call the image initializer function
3922 if it is defined. Arguments and return value changed.
3923 (valid_image_p, make_image): Callers changed.
3924 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3925 (gif_type, imagemagick_type, svg_type, gs_type):
3926 Add initialization functions.
3927 (Finit_image_library): Call lookup_image_type.
3928 (CHECK_LIB_AVAILABLE): Macro deleted.
3929 (lookup_image_type): Call define_image_type here, rather than via
3930 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3931 (syms_of_image): Move define_image_type calls for xbm_type and
3932 pbm_type to lookup_image_type.
3934 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3936 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3937 'idle_timers' from here ...
3938 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3939 lists, to avoid infloops when the timer does something stupid,
3940 like reinvoke itself with the same or smaller time-out.
3943 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3945 * window.c (Fsplit_window_internal): Handle only Qt value of
3946 Vwindow_combination_limit separately.
3947 (Qtemp_buffer_resize): New symbol.
3948 (Vwindow_combination_limit): New default value.
3951 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3953 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3954 the new overlay string. (Bug#10159)
3956 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3958 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3959 or that fprintf is async-signal-safe. POSIX doesn't require
3962 2012-09-22 Chong Yidong <cyd@gnu.org>
3964 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3967 2012-09-22 Kenichi Handa <handa@gnu.org>
3969 * composite.c (composition_reseat_it): Handle the case that a
3970 grapheme cluster is not covered by a single font (Bug#12352).
3972 2012-09-21 Chong Yidong <cyd@gnu.org>
3974 * image.c (define_image_type): Avoid adding duplicate types to
3975 image_types (Bug#12463). Suggested by Jörg Walter.
3977 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3979 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3980 (print_load_command_name): Add case LC_DATA_IN_CODE.
3981 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3983 2012-09-21 Glenn Morris <rgm@gnu.org>
3985 * eval.c (Frun_hook_with_args_until_success)
3986 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3988 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3990 * fileio.c (Ffile_selinux_context): Only call freecon when
3991 lgetfilecon succeeded.
3992 (Fset_file_selinux_context): Likewise. (Bug#12444)
3994 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3996 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3997 reordering, locate the cursor by calling set_cursor_from_row; if
3998 that fails, clear the desired glyph matrix before returning a
3999 failure indication to the caller. Fixes leaving garbled display
4000 when fast scrolling with a down-key. (Bug#12403)
4001 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4002 scrolling through multibyte text.
4004 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4006 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4007 calling mark_vectorlike since that's the one that marks the window.
4008 (mark_discard_killed_buffers): Mark the final cdr.
4009 * window.h (struct window): Move prev/next_buffers to the
4010 non-standard fields.
4011 * window.c (make_window): Initialize prev/next_buffers manually.
4013 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4015 Omit unused arg EXPECTED from socket hooks.
4016 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4017 * nsterm.m (ns_term_init):
4018 * termhooks.h (struct terminal.read_socket_hook):
4019 * w32inevt.c (w32_console_read_socket):
4020 * w32term.c (w32_read_socket):
4021 * xterm.c (XTread_socket):
4022 Omit unused arg EXPECTED. All callers changed.
4023 (store_user_signal_events): Return void, not int, since callers no
4024 longer care about the return value. All uses changed.
4026 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4028 * w32gui.h (XParseGeometry): Do not declare.
4030 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4032 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4033 Ignore 'expected'. See Eli Zaretskii in
4034 <http://bugs.gnu.org/12471#8> (last line).
4036 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4037 (XParseGeometry): Now static. Substitute extremal values for
4038 values that are out of range.
4040 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4042 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4044 * nsfns.m (XParseGeometry): Remove.
4045 (Fx_create_frame): Call x_set_offset to correctly interpret
4046 top_pos in geometry.
4048 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4049 (Fx_parse_geometry): If there is a space in string, call
4050 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4052 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4054 * search.c (scan_buffer): Use character positions in calls to
4055 region_cache_forward and region_cache_backward, not byte
4056 positions. (Bug#12196)
4058 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4059 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4061 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4062 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4063 emacs_blocked_malloc, now deleted.
4065 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4067 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4068 The workaround was for improving performance on Solaris 2.4, but
4069 is getting in the way now. Emacs will still work if someone is
4070 still running Solaris 2.4 in a museum somewhere; Sun dropped
4071 support for Solaris 2.4 in 2003.
4072 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4073 * process.c (create_process) [HAVE_WORKING_VFORK]:
4074 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4075 since Emacs no longer uses vfork on that platform.
4077 2012-09-17 Glenn Morris <rgm@gnu.org>
4079 * emacs.c: Use COPYRIGHT.
4081 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4083 Remove configure's --without-sync-input option (Bug#12450).
4084 When auditing signal-handling in preparation for cleaning it up,
4085 I found that SYNC_INPUT has race conditions and would be a real
4086 pain to fix. Since it's an undocumented and deprecated
4087 configure-time option, now seems like a good time to remove it.
4088 Also see <http://bugs.gnu.org/11080#16>.
4089 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4090 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4091 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4092 (malloc_hysteresis):
4093 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4094 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4095 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4096 (dont_register_blocks, bytes_used_when_reconsidered)
4097 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4098 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4099 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4100 Remove. All uses removed.
4101 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4102 implementation, one that depends on whether the new macro
4103 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4105 * atimer.c (run_timers, handle_alarm_signal):
4106 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4107 (handle_async_input, process_pending_signals)
4108 (handle_input_available_signal, init_keyboard):
4109 * nsterm.m (ns_read_socket):
4110 * process.c (wait_reading_process_output):
4111 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4112 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4114 * xterm.c (XTread_socket):
4116 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4117 * eval.c (handling_signal): Remove. All uses removed.
4118 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4119 All uses replaced with the SYNC_INPUT version.
4120 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4122 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4125 * font.c (Ffont_shape_gstring): Remove unused local.
4127 2012-09-16 Glenn Morris <rgm@gnu.org>
4129 * Makefile.in (clean): No longer run nextstep's clean.
4131 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4133 (ns-app): Move here from ns.mk, and simplify.
4134 (clean): Simplify nextstep entry.
4135 * ns.mk: Remove file.
4137 2012-09-17 Kenichi Handa <handa@gnu.org>
4139 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4140 not covert the last few charactes.
4142 2012-09-16 Kenichi Handa <handa@gnu.org>
4144 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4145 here, but just check the validity of glyphs in the glyph-string.
4147 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4149 * window.c (Fwindow_parameter, Fset_window_parameter):
4150 Accept any window as argument (Bug#12452).
4152 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4154 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4155 to ns_term_init to avoid memory leak.
4157 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4158 explicit retain/release.
4159 (ns_term_init): Only allow one display. Initialize outerpool and
4162 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4164 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4165 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4166 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4167 the Microsoft problem in a different way, by altering ../nt/config.nt.
4169 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4184 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4185 by lisp.h. This completes removal of setjmp.h inclusion
4186 erroneously announced in the previous commit. (Bug#12446)
4188 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4191 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4192 not defined as a macro. The latter happens on MS-Windows.
4195 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4197 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4198 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4199 Some instances of '#include <setjmp.h>' removed, if the
4200 only reason for the instance was because "lisp.h" was included.
4201 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4202 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4203 and _longjmp with the new symbols. Emacs already uses _setjmp if
4204 available, so this change affects only POSIXish hosts that have
4205 sigsetjmp but not _setjmp, such as some versions of Solaris and
4206 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4207 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4208 (png_load_body) [HAVE_PNG]:
4209 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4210 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4211 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4212 since PNG requires jmp_buf. This is the only exception to the
4213 general rule that we now use sys_setjmp and sys_longjmp.
4214 This exception is OK since this code does not change the signal
4215 mask or longjmp out of a signal handler.
4217 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4219 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4220 Include "syssignal.h", for 'main_thread'.
4222 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4224 Avoid out-of-range marker position (Bug#12426).
4225 * insdel.c (replace_range, replace_range_2):
4226 Adjust markers before overlays, as suggested by comments.
4227 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4228 Remove redundant check before calling offset_intervals.
4230 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4232 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4233 current buffer (Bug#12387).
4235 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4237 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4239 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4241 Use a more backwards-compatible timer format (Bug#12430).
4242 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4243 vector element, not from the 4th, since PSECS is now at the end.
4244 (Fcurrent_idle_time): Doc fix.
4246 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4248 Function to mark objects and remove killed buffers at once.
4249 * alloc.c (discard_killed_buffers): Rename to ...
4250 (mark_discard_killed buffers) ... new name. Add marking
4251 of remaining objects. Fix comment. Adjust users.
4252 (mark_object): Do not touch frame buffer lists here.
4253 * frame.c (delete_frame): Reset frame buffer lists here.
4255 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4257 Better workaround for GNOME bug when --enable-gcc-warnings.
4258 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4259 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4260 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4262 Simplify SIGIO usage (Bug#12408).
4263 The code that dealt with SIGIO was crufty and confusing, e.g., it
4264 played tricks like "#undef SIGIO" but these tricks were not used
4265 consistently. Simplify mostly by not #undeffing standard symbols,
4266 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4267 or not as we please) rather than "defined SIGIO" (standard symbol
4268 that we probably shouldn't #undef).
4269 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4270 Modules that need it can include it.
4271 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4272 * dispextern.h (ignore_sigio): New decl.
4273 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4274 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4275 * emacs.c (shut_down_emacs):
4276 * keyboard.c (kbd_buffer_store_event_hold):
4277 Use ignore_sigio rather than invoking 'signal' directly.
4278 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4280 (FIONREAD, SIGIO): Do not #undef.
4281 (tty_read_avail_input): Use #error rather than a syntax error.
4282 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4283 for I_PIPE, used by SETUP_SLAVE_PTY.
4284 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4285 * sysdep.c (croak): Remove; no longer needed. This bit of
4286 temporary code, with Fred N. Fish's comment that it's temporary,
4287 has been in Emacs since at least 1992!
4288 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4289 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4290 * syssignal.h (croak): Remove decl.
4291 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4292 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4293 now that we're termios-only.
4294 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4295 * term.c (dissociate_if_controlling_tty): Use #error rather than
4298 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4299 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4300 to work around GNOME bug 683906.
4301 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4302 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4303 This works around GCC bug 54561.
4305 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4307 More fixes for 'volatile' and setjmp/longjmp.
4308 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4309 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4310 (png_load_body) [HAVE_PNG]:
4311 (jpeg_load_body) [HAVE_JPEG]:
4312 New function, with most of the old parent function's body.
4313 (png_load) [HAVE_PNG]:
4314 (jpeg_load) [HAVE_JPEG]:
4315 Invoke the new function, to avoid longjmp munging our locals.
4316 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4317 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4318 longjmp is passed 2, as the C standard doesn't guarantee this.
4319 Instead, store the failure code into mgr->failure_code.
4321 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4323 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4324 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4325 (syms_of_keyboard): Remove support for unread-command-char.
4327 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4329 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4330 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4331 violation. (Bug#12426)
4333 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4335 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4337 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4339 * eval.c: Add `inhibit-debugger'.
4340 (Qinhibit_debugger): New symbol.
4341 (call_debugger): Bind it instead of Qdebug_on_error.
4342 (maybe_call_debugger): Test Vinhibit_debugger.
4343 (syms_of_eval): Define inhibit-debugger.
4344 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4345 (syms_of_xdisp): Remove inhibit-debug-on-message.
4347 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4349 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4350 If a nonvolatile local variable is written before a _longjmp to
4351 the frame containing the variable, and is read after the _longjmp,
4352 the value read is indeterminate. Some local variables of type
4353 'struct handler' and 'struct catchtag' are used in this way, so
4354 mark each of their slots as volatile if the slot can be set before
4355 _longjmp and read afterwards.
4356 * lisp.h (struct handler): var and chosen_clause are now volatile.
4357 (struct catchtag): val, next, and pdlcount are now volatile.
4359 * bidi.c (bidi_push_it, bidi_pop_it):
4360 * fns.c (copy_hash_table):
4361 * image.c (define_image_type):
4362 * keyboard.c (kbd_buffer_store_event_hold):
4363 * process.c (Fprocess_send_eof):
4364 * xfaces.c (x_create_gc) [HAVE_NS]:
4365 * xgselect.c (xg_select):
4366 Prefer assignment to memcpy when either will do.
4368 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4369 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4370 time an item is removed. No need to mark this function 'inline';
4371 the compiler knows better than we do.
4373 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4375 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4376 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4377 to change_frame_size (Bug#12388).
4378 (windowDidResize:): Pass YES to updateFrameSize.
4380 * nsterm.h: Add delay parameter to updateFrameSize.
4382 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4384 Discard killed buffers from deleted window and frame objects.
4385 This reduces an amount of references to killed buffers and
4386 helps GC to reclaim them faster.
4387 * alloc.c (discard_killed_buffers): New function.
4388 (mark_object): Use it for deleted windows and frames.
4389 (mark_object): If symbol's value is set up for a killed buffer
4390 or deleted frame, restore its global binding.
4391 * data.c (swap_in_global_binding): Add GC notice.
4392 (swap_in_symval_forwarding): Use convenient set_blv_where.
4393 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4394 * window.h: ... to here.
4396 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4398 Convenient macro to check whether the buffer is live.
4399 * buffer.h (BUFFER_LIVE_P): New macro.
4400 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4401 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4403 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4405 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4406 composition cases (Bug#12364).
4408 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4409 overhang of succeeding glyphs overlapping box cursor.
4411 * w32term.c (x_draw_glyph_string): Likewise.
4413 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4415 Simplify, document, and port floating-point (Bug#12381).
4416 The porting part of this patch fixes bugs on non-IEEE platforms
4417 with frexp, ldexp, logb.
4418 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4420 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4421 support, by removing commented-out code and briefly listing the
4422 C89 functions excluded. The commented-out stuff was confusing
4423 maintenance, e.g., we thought we needed cbrt but it was commented out.
4424 (logb): Remove decl; no longer needed.
4425 (isfinite): New macro, if not already supplied.
4426 (isnan): Don't replace any existing macro.
4427 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4428 are present on all C89 platforms.
4429 (Ffrexp): Do not special-case zero, as frexp does the right thing
4431 (Flogb): Do not use logb, as it doesn't have the desired meaning
4432 on hosts that use non-base-2 floating point. Instead, stick with
4433 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4434 frexp, to avoid getting an unspecified result.
4436 * xdisp.c (Qinhibit_debug_on_message): Now static.
4438 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4440 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4441 NSBezierPath (Bug#12131).
4443 2012-09-10 Chong Yidong <cyd@gnu.org>
4445 * fns.c (Fdelq, Fdelete): Doc fix.
4447 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4449 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4450 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4452 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4454 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4455 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4458 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4460 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4461 left fringe if the window has a left margin. This avoids leaving
4462 traces of the cursor because its leftmost pixel is not drawn over.
4464 * dispnew.c (update_window_line): When the left margin area of a
4465 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4466 that screen line. (Bug#12277)
4468 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4470 Assume C89 or later for math functions (Bug#12381).
4471 This simplifies the code, and makes it a bit smaller and faster,
4472 and (most important) makes it easier to clean up signal handling
4473 since we can stop worring about floating-point exceptions in
4474 library code. That was a problem before C89, but the problem
4475 went away many years ago on all practical Emacs targets.
4476 * data.c, image.c, lread.c, print.c:
4477 Don't include <math.h>; no longer needed.
4478 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4479 might be autoconfigured, as that never happens.
4481 * doprnt.c (DBL_MAX_10_EXP):
4482 * print.c (DBL_DIG):
4483 Remove. C89 or later always defines these.
4484 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4485 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4486 (arith_error, domain_error, domain_error2):
4487 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4488 no longer needed -- we simply return what C returns. All uses removed.
4489 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4491 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4492 Remove. All uses expanded, as these macros are no longer used
4493 more than once and are now more trouble than they're worth.
4494 (Ftan): Use tan, not sin / cos.
4495 (Flogb): Assume C89 frexp.
4496 (fmod_float): Assume C89 fmod.
4497 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4498 (init_floatfns): Remove. All uses removed.
4500 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4502 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4503 compositeToPoint for OSX < 10.6 (Bug#12390).
4505 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4507 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4508 This produces more-accurate results.
4510 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4512 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4513 changes (Bug#12088).
4515 2012-09-08 Chong Yidong <cyd@gnu.org>
4517 * syntax.c (Fstring_to_syntax): Doc fix.
4519 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4521 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4522 in the internal border.
4523 (x_set_window_size): Remove static variables and their usage.
4524 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4525 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4526 Remove fringe/internal border adjustment (Bug#11052).
4527 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4528 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4529 (ns_fix_rect_ibw): Remove.
4530 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4531 (ns_dumpglyphs_box_or_relief): Ditto.
4532 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4534 (ns_dumpglyphs_image): Ditto.
4535 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4537 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4538 their usage. Add fringe_extended_p and its use as in other terms.
4539 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4540 scroll bar was removed.
4541 (updateFrameSize): New function.
4542 (windowDidResize): Move code to updateFrameSize and call it.
4544 * nsterm.h (EmacsView): Add updateFrameSize.
4546 2012-09-07 Chong Yidong <cyd@gnu.org>
4548 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4550 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4552 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4554 More signal-handler cleanup (Bug#12327).
4555 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4556 Problem introduced when merging patches. Noted by Eli Zaretskii in
4557 <http://bugs.gnu.org/12327#67>.
4558 * floatfns.c: Comment fix.
4559 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4560 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4561 and anyway the declaration is harmless even if SIGDANGER is not defined.
4562 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4563 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4564 source files not surprisingly expected syssignal.h to define, or
4565 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4566 Include <sys/ioctl.h>, for FIONREAD.
4567 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4568 This eliminates a problem whereby other files mysteriously had
4569 to include "syssignal.h" before including "systty.h" if they
4570 wanted to use "#ifdef SIGIO".
4572 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4574 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4576 * w32.c (sigemptyset): Empty the set.
4577 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4579 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4581 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4583 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4584 (mark_object): Likewise for frame objects.
4586 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4588 * syssignal.h (handle_on_main_thread): Always declare,
4589 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4590 This ports to platforms without HAVE_PTHREAD.
4592 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4594 Signal-handler cleanup (Bug#12327).
4595 Emacs's signal handlers were written in the old 4.2BSD style with
4596 sigblock and sigmask and so forth, and this led to some
4597 inefficiencies and confusion. Rewrite these to use
4598 pthread_sigmask etc. without copying signal sets around. Also,
4599 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4600 'signal', and instead use functions that do not attempt to take
4601 over the system name space. This patch causes Emacs's text
4602 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4603 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4604 Do not include <signal.h> or "syssignal.h", as these
4605 modules do not use signals.
4606 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4607 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4608 Do not include <signal.h>, as "syssignal.h" does that for us now.
4609 * atimer.c (sigmask_atimers): New function.
4610 (block_atimers, unblock_atimers): New functions,
4611 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4613 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4614 no longer needed here.
4615 * emacs.c (main): Inspect existing signal handler with sigaction,
4616 so that there's no need to block and unblock SIGHUP.
4617 * sysdep.c (struct save_signal): New member 'action', replacing
4618 old member 'handler'.
4619 (save_signal_handlers, restore_signal_handlers):
4620 Use sigaction instead of 'signal' to save and restore.
4621 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4622 New function. All users of 'signal' modified to use set_sighandler
4623 if they're writeonly, and to use sys_signal if they're read+write.
4624 (emacs_sigaction_init, forwarded_signal): New functions.
4625 (sys_signal): Remove. All uses replaced by calls to sigaction
4626 and emacs_sigaction_init, or by direct calls to 'signal'.
4627 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4628 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4629 all uses replaced by pthread_sigmask etc. calls.
4630 * syssignal.h: Include <signal.h>.
4631 (emacs_sigaction_init, forwarded_signal): New decls.
4632 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.

4635 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4636 (sigblock, sigunblock, sigfree):
4637 (sigsetmask) [!defined sigsetmask]:
4638 Remove. All uses replaced by pthread_sigmask.
4639 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4640 no longer need to be replaced, and its typical old uses
4641 are now done via emacs_sigaction_init and sigaction.
4642 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4643 (sys_sigdel): Remove; unused.
4644 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4646 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4648 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4649 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4651 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4653 Explicitly mark buffer_defaults and buffer_local_symbols.
4654 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4655 mark_local_symbols here.
4656 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4657 since special buffers aren't marked here any more.
4658 (allocate_buffer): Chain new buffer with all_buffers here...
4659 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4661 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4662 (syms_of_buffer): Remove staticpro of the above.

4666 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4668 Use bool for booleans in font-related modules.
4669 * font.c (font_intern_prop, font_style_to_value)
4670 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4671 (generate_otf_features, font_check_otf_features, font_check_otf)
4672 (font_match_p, font_list_entities, font_at):
4673 * fontset.c (fontset_id_valid_p, reorder_font_vector
4674 (fontset_find_font, Fset_fontset_font)
4675 (face_suitable_for_char_p) [0]:
4676 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4677 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4678 (m17n_flt_initialized, ftfont_shape_by_flt):
4679 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4680 * nsfont.m (nsfont_draw):
4681 * w32font.c (w32font_draw):
4682 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4683 Use bool for booleans.
4684 * font.h: Adjust to above API changes.
4685 (struct font, struct font_driver, struct font_driver_list):
4686 Use bool for booleans.
4687 (struct font): Remove useless member encoding_type.
4689 * fontset.c, xftfont.c: Omit unnecessary static decls.
4691 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4693 * alloc.c (mark_object): Revert window marking code
4694 since it's unsafe for the Fset_window_configuration.
4696 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4698 Fix race conditions with signal handlers and errno (Bug#12327).
4699 Be more systematic about preserving errno whenever a signal
4700 handler returns, even if it's not in the main thread. Do this by
4701 renaming signal handlers to distinguish between signal delivery
4702 and signal handling. All uses changed.
4703 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4704 * data.c (deliver_arith_signal): Rename from arith_error.
4705 * dispnew.c (deliver_window_change_signal): Rename from
4706 window_change_signal.
4707 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4708 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4709 * keyboard.c (deliver_input_available_signal): Rename from
4710 input_available_signal.
4711 (deliver_user_signal): Rename from handle_user_signal.
4712 (deliver_interrupt_signal): Rename from interrupt_signal.
4713 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4714 (deliver_child_signal): Rename from sigchld_handler.
4715 * atimer.c (handle_alarm_signal):
4716 * data.c (handle_arith_signal):
4717 * dispnew.c (handle_window_change_signal):
4718 * emacs.c (handle_fatal_signal, handle_danger_signal):
4719 * keyboard.c (handle_input_available_signal):
4720 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4721 * process.c (handle_pipe_signal, handle_child_signal):
4722 New functions, with the actual signal-handling code taken from the
4723 original respective signal handlers, sans the sporadic attempts to
4724 preserve errno, since that's now done by handle_on_main_thread.
4725 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4726 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4727 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4729 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4730 Move initialization of main_thread to sysdep.c's init_signals.
4731 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4732 our usage, and simplifies the mainline code.
4733 (record_child_status_change): New static function, as a helper
4734 for handle_child_signal, and with most of the old child handler's
4736 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4737 (handle_child_signal): Use the above.
4738 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4739 Moved here from emacs.c.
4740 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4741 code moved here from emacs.c's main function.
4742 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4743 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4744 This lets callers save and restore errno properly.
4746 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4748 Remove redundant or unused things here and there.
4749 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4750 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4751 * editfns.c (Fcompare_buffer_substrings): Likewise.
4752 * frame.h (struct terminal, struct font_driver_list):
4753 Remove redundant declarations.
4754 * window.h (Qleft, Qright): Likewise.
4756 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4758 Do not mark objects from deleted buffers, windows and frames.
4759 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4760 (mark_object): Likewise for windows and frames.
4762 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4764 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4765 buffer_defaults and buffer_local_symbols as valid objects.
4766 Return special value to denote them.
4768 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4770 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4771 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4772 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4773 (file_name_absolute_p, Fsubstitute_in_file_name):
4774 (check_executable, check_writable, Ffile_accessible_directory_p)
4775 (Fset_file_selinux_context, Fdefault_file_modes)
4776 (Finsert_file_contents, choose_write_coding_system)
4777 (Fwrite_region, build_annotations, a_write, e_write)
4779 * filelock.c (boot_time_initialized, get_boot_time)
4780 (get_boot_time_1, lock_file_1, within_one_second):
4781 * floatfns.c (in_float):
4782 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4783 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4784 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4785 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4786 * window.c (compare_window_configurations):
4787 Use bool for booleans.
4788 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4789 (Fdefault_file_modes): Now mode_t, not int, for modes.
4790 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4791 (internal_delete_file): Now returns void, not a (boolean) int,
4792 since nobody was looking at the return value.
4793 * lisp.h, window.h: Adjust to above API changes.
4795 * xdisp.c (set_message): Simplify and reindent last change.
4797 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4799 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4801 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4803 * eval.c (call_debugger): Make the function non-static so that we
4804 can call it from set_message.
4806 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4807 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4809 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4811 Give more-useful info on a fatal error (Bug#12328).
4812 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4813 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4814 of doing the work ourselves.
4815 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4816 do most of the work.
4817 (fatal_error_backtrace): New function, taken from the guts
4818 of the old fatal_error_signal, but with a new option to output
4820 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4821 info about the signal than just its number.
4822 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4823 * sysdep.c: Include <execinfo.h>
4824 (emacs_backtrace): New function, taken partly from the previous
4825 code of the 'die' function.
4826 (emacs_abort): Call fatal_error_backtrace rather than abort.
4828 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4830 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4831 eager (load-time) macro-expansion.
4832 * lisp.mk (lisp): Add macroexp.
4834 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4836 Simplify redefinition of 'abort' (Bug#12316).
4837 Do not try to redefine the 'abort' function. Instead, redo
4838 the code so that it calls 'emacs_abort' rather than 'abort'.
4839 This removes the need for the NO_ABORT configure-time macro
4840 and makes it easier to change the abort code to do a backtrace.
4841 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4842 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4843 Remove; sysdep.c's emacs_abort now takes its place.
4844 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4845 'abort' changed to use 'emacs_abort'.
4846 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4847 (abort) [!defined abort]: Rename to ...
4848 (emacs_abort): ... new name.
4849 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4850 the place of the old 'abort' in emacs.c.
4851 * w32.c, w32fns.c (abort): Do not #undef.
4852 * w32.c (emacs_abort): Rename from w32_abort.
4854 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4856 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4857 offsets[j].dv, since the y axis of the screen coordinates points
4858 down, while the y axis of the font definition coordinates points
4859 up. This fixes display of Arabic diacritics such as KASRA and
4860 KASRATAN. (Bug#11860)
4862 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4864 Be more systematic about _setjmp vs setjmp.
4865 * alloc.c (test_setjmp, mark_stack):
4866 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4867 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4868 (png_load, my_error_exit, jpeg_load):
4869 * process.c (send_process_trap, send_process):
4870 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4871 The underscored versions are up to 30x faster on some hosts.
4872 Formerly, the code used setjmp+longjmp sometimes and
4873 _setjmp+_longjmp at other times, with no particular reason to
4874 prefer setjmp+longjmp.
4876 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4878 Fix minor problem found by static checking.
4879 * buffer.c (Fdelete_all_overlays): Return nil.
4881 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4883 * buffer.c (Fdelete_all_overlays): New function.
4885 2012-09-03 Chong Yidong <cyd@gnu.org>
4887 * gtkutil.c: Add extern decl for Qxft.
4889 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4891 * emacs.c, eval.c: Use bool for boolean.
4892 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4893 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4894 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4895 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4896 (main, decode_env_path, Fdaemon_initialized):

4898 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4899 (maybe_call_debugger, Fbacktrace):
4900 * process.c (read_process_output, exec_sentinel):
4901 Use bool for booleans.
4902 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4903 All callers changed.
4904 * eval.c (interactive_p): Omit always-true boolean argument
4905 EXCLUDE_SUBRS_P. All callers changed.
4906 * dispextern.h, lisp.h: Reflect above API changes.
4907 * firstfile.c (dummy): Use the address of 'main', whose signature
4908 won't change, instead of the address of 'initialize', whose
4909 signature just changed from int to bool.
4910 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4911 * msdos.c (fatal_error_in_progress): ... from here.
4912 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4914 (redisplay_internal, unwind_redisplay): Simply clear
4915 REDISPLAYING_P when unwinding, instead of saving its previous,
4916 always-false value and then restoring it.
4918 Clean up some extern decls.
4919 Mostly, this hoists extern decls out of .c files and into .h files.
4920 That way, we're more likely to catch errors if the interfaces change.
4921 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4922 declare xg_mark_data.
4923 * dispextern.h (x_frame_parm_handlers):
4925 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4926 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4927 (Qultra_bold, Qoblique, Qitalic):
4928 Move extern decl here from .c file.
4929 * alloc.c (xg_mark_data) [USE_GTK]:
4931 * eval.c (Qlexical_binding):
4932 * fns.c (time) [!HAVE_UNISTD_H]:

4938 * process.c (QCfamily, QCfilter):
4939 * widget.c (free_frame_faces):
4940 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4941 * xfont.c (x_clear_errors):
4942 * xterm.c (x_frame_parm_handlers):
4943 Remove now-redundant extern decls.
4944 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4945 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4947 * xfaces.c: Remove unnecessary static decls.
4948 * xterm.c (updating_frame): Remove decl of nonexistent object.
4950 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4951 when building globals.h, as the objects that are not built on
4952 this host are not needed to compile C files on this host.
4954 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4956 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4958 * frame.h: Add missing prototype for x_wm_set_size_hint.
4960 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4964 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4965 (Fsubstitute_command_keys):

4967 (save_excursion_save, save_excursion_restore)
4968 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
4969 (format_time_string, general_insert_function)
4970 (make_buffer_string, make_buffer_string_both)
4971 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

4984 * keyboard.c (decode_timer):
4985 Use bool for boolean.
4986 * intervals.h, lisp.h, systime.h: Reflect above API changes.
4987 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
4989 2012-09-02 Chong Yidong <cyd@gnu.org>
4991 * keymap.c (push_key_description): Print M-TAB as C-M-i
4994 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4996 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4997 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
4998 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

5002 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5004 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5006 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5007 more than one grapheme cluster passed to the shaper: compute the
5008 offset adjustment values separately for each cluster. (Bug#11860)
5010 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5011 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5012 about implicit conversions from integer to pointer.
5014 2012-09-01 Daniel Colascione <dancol@dancol.org>
5016 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

5331 Special MEM_TYPE_SPARE to denote reserved memory.
5332 * alloc.c (enum mem_type): New memory type.
5333 (refill_memory_reserve): Use new type for spare memory.

5369 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5370 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5371 are all boolean, so make them single-bit bitfields.
5373 * lisp.h (ASET): Remove attempt to detect side effects.
5374 It was meant to be temporary and it often doesn't work,
5375 because when IDX has side effects the behavior of IDX==IDX
5376 is undefined. See Stefan Monnier in
5377 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5379 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

5382 (FUNCTIONP): Use it.

5387 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5388 as that's faster and simpler than static storage. Don't bother
5389 with the g_main_context_query overhead if g_main_context_pending
5390 says no events are pending.
5391 (gfds, gfds_size): Remove these static vars.
5392 (xgselect_initialize): Remove; no longer needed.
5393 All uses and decls removed.
5395 * emacs.c (fatal_error_signal_hook): Remove.
5396 All uses removed. This leftover from old code was always 0.

5423 Use bool for booleans, instead of int.
5424 * lisp.h, process.h: Adjust prototypes to match above changes.
5425 * callint.c (Fcall_interactively): Don't assume the mark's
5426 offset fits in 'int'.

5439 Use bool for booleans, instead of int.
5440 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5441 since the 1-or-0 return value is always ignored anyway.
5442 (mmap_initialized_p):
5443 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5444 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5446 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5448 * bidi.c: Use bool for boolean.
5449 This is a bit more readable, and makes the text segment of bidi.o
5450 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5451 Presumably it's faster too.

5475 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5476 compile time tests instead of run time tests on systems that do
5478 (FRAME_MAC_P): Remove leftover from deleted code.

5485 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5487 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5488 Otherwise, the compiler complains about (A?B:C) where B is void
5489 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5490 (fontset_add): Return void, for FONTSET_ADD.
5492 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5494 * alloc.c: Use bool for booleans.
5495 (gc_in_progress, abort_on_gc)
5496 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5497 (dont_register_blocks) [GC_MALLOC_CHECK]:
5498 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5499 (check_string_bytes, make_specified_string, memory_full)
5500 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5501 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5502 (mark_stack, valid_pointer_p, make_pure_string)
5503 (Fgarbage_collect, survives_gc_p, gc_sweep):
5504 Use bool for booleans, instead of int.
5505 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5506 Remove unused local.
5507 * alloc.c (PURE_POINTER_P):
5508 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5509 * editfns.c (Fformat):
5510 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5512 * fns.c (sweep_weak_table):
5513 * lisp.h (suppress_checking, push_message, survives_gc_p)
5514 (make_pure_string, gc_in_progress, abort_on_gc):
5515 * lread.c (readchar, read1):
5516 * print.c (Fprin1_to_string):
5517 * xdisp.c (push_message):
5518 Use bool for booleans affected directly or indirectly by
5521 Make recently-introduced setters macros.
5522 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5523 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5524 (set_fontset_default, set_fontset_fallback): Rename from their
5525 upper-case counterparts, and make them functions rather than macros.
5526 This is more consistent with the other recently-introduced setters.
5527 These don't need to be inline, since they're local.
5529 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5531 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5532 the loop (Bug#12247).
5534 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5536 * lisp.h (vcopy): Use memcpy rather than our own loop.
5537 This fixes a performance regression introduced by the recent
5538 addition of vcopy. This means 'vcopy' will need to be modified
5539 for a copying collector, but that's OK. Also, tighten the
5540 checking in the assertion.
5542 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5544 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5545 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5546 non-base glyph for the width of the base character, according to
5547 what x_draw_composite_glyph_string_foreground expects.
5548 Generate WADJUST value according to composition_gstring_width's
5549 expectations, to produce correct width of the composed character.
5550 Reverse the sign of the DU offset produced by ScriptPlace.
5552 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5554 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5556 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5558 Avoid direct writes to contents member of struct Lisp_Vector.
5559 * lisp.h (vcopy): New function to copy data into vector.
5560 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5561 * fns.c (Ffillarray): Use ASET.
5562 * keyboard.c (timer_check_2): Use AREF and ASET.
5563 (append_tool_bar_item, Frecent_keys): Use vcopy.
5564 * lread.c (read_vector): Use ASET.
5565 * msdos.c (Frecent_doskeys): Use vcopy.
5566 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5567 (Finternal_merge_in_global_face): Use ASET and vcopy.
5568 * xfont.c (xfont_list_pattern): Likewise.

5573 the position of its buffer's point.
5574 (Fset_window_point): For the selected window always go in its
5575 buffer to the specified position.
5577 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5579 Setter macros for fontsets.
5580 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5581 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5582 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5585 2012-08-20 Glenn Morris <rgm@gnu.org>
5587 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5588 Don't assume that `ln -f' works.
5590 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5592 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5593 and later about non-assignments with no effect. See discussion at
5594 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5597 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5599 Inline setter functions for Lisp_Objects slots of struct specbinding.
5600 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5603 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5605 * window.c (select_window): Always make selected window's buffer
5608 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5610 Use AREF and ASET for docstrings of category tables.
5611 * category.h (CATEGORY_DOCSTRING): Use AREF.
5612 (SET_CATEGORY_DOCSTRING): Use ASET.
5613 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5615 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5617 Inline setter functions for hash table members.
5618 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5619 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5620 (set_hash_key_and_value, set_hash_index, set_hash_next)
5621 (set_hash_hash): New functions.
5622 * charset.c, fns.c: Adjust users.
5624 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5626 Inline getter and setter functions for per-buffer values.
5627 * buffer.h (per_buffer_default, set_per_buffer_default)
5628 (per_buffer_value, set_per_buffer_value): New functions.

5630 * buffer.c, data.c: Adjust users.
5632 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5634 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5636 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5638 Rely on <config.h> + <unistd.h> to declare 'environ',
5639 as gnulib does this if the system doesn't.
5640 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5641 Remove declaration. MS-Windows declares it on stdlib.h which is
5642 included by conf_post.h.
5643 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5644 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5645 * vm-limit.c: Include <unistd.h>, for 'environ'.
5647 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5648 (start_of_data): Remove decl; mem-limits.h provides it.
5650 * xdisp.c (handle_invisible_prop): Make it a bit faster
5651 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5653 2012-08-19 Chong Yidong <cyd@gnu.org>
5655 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5658 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>

5663 * data.c (set_internal): Don't use set_blv_found.
5664 (Fkill_local_variable): Likewise.
5666 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5668 * nsfont.m (ns_ascii_average_width): Ensure the string
5669 ascii_printable is initialized with a null-terminated character
5670 array. Otherwise, it can contain undesired extra characters.
5672 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5674 port new setting code to Sun C 5.8 2005/10/13
5675 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5676 Return void, not Lisp_Object. Otherwise, the compiler
5677 complains about (A?B:C) where B is void and C is Lisp_Object
5678 when compiling CHAR_TABLE_SET, due to the recent change to
5679 the API of sub_char_table_set_contents.
5681 2012-08-18 Chong Yidong <cyd@gnu.org>
5683 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5684 for the string case (Bug#3874).

5839 The old version was confusing because it used the same name
5840 'parent' for two different things.

5854 directly-specified attributes.
5855 (merge_face_ref): Recognize :font.
5857 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

6511 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6512 * w32.c (init_environment): Change the default values of many
6513 environment variables in dflt_envvars[] to NULL, to avoid pushing
6514 them into environment when they were not already defined.
6515 Remove the code that deletes site-lisp subdirectories from the default
6516 value of EMACSLOADPATH, as it is no longer needed.
6517 (check_windows_init_file): Now external, not static.
6518 Use Vload_path as is, without adding anything, as this function is now
6519 called when Vload_path is already set up.
6521 * w32.h (check_windows_init_file): Add prototype.
6523 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6530 installation tree, as appropriate.
6532 * callproc.c (init_callproc_1): Call decode_env_path instead of
6533 doing its equivalent by hand.

6535 the code that sets Vexec_path run on MS-Windows.
6537 * lread.c (init_lread): Add comments to #ifdef's.
6539 * msdos.c (dos_set_window_size, IT_update_begin)

6551 Remove unnecessary casts involving pointers.
6552 These casts are no longer needed now that we assume C89 or later,

6566 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6567 Remove unnecessary pointer casts.
6568 * alloc.c (record_xmalloc): New function.
6569 * lisp.h (record_xmalloc): New decl.
6570 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6571 more like a function. This is because the pointer cast is not
6572 needed. All uses changed.
6573 * print.c (print_string, print_error_message): Avoid length recalc.
6575 Improve fix for macroexp crash with debugging (Bug#12118).
6576 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6577 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6578 not supposed to be invoked from the garbage collector.
6579 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6580 (gc_aset): New function, which is like ASET but can be
6581 used in the garbage collector.
6582 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

6597 headers (most versions of MinGW w32api don't).
6598 (get_security_info, create_symbolic_link)
6599 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

6610 with addition of handling of symlinks and support for 'lstat'.
6611 If possible, get file's attributes and security information by
6612 handle, not by name. Produce S_IFLNK bit for symlinks, when
6613 called from 'lstat'.
6614 (stat, lstat): New functions, call 'stat_worker'.
6615 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6616 symlinks when the underlying filesystem supports them.
6618 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6620 Fix macroexp crash on Windows with debugging (Bug#12118).
6621 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6622 checking subscripts; problem introduced with the recent
6623 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6624 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6625 since it's used in non-static inline functions now.
6627 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6628 Don't assume buffer size fits in 'int'. Remove unused local.

6645 * category.c (CATEGORY_INLINE):
6646 * character.c (CHARACTER_INLINE):
6647 * charset.c (CHARSET_INLINE):
6648 * composite.c (COMPOSITE_INLINE):
6649 * dispnew.c (DISPEXTERN_INLINE):
6650 * sysdep.c (SYSTIME_INLINE):
6651 Define to EXTERN_INLINE, so that the corresponding functions
6652 are compiled into code.
6653 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6654 (INLINE_HEADER_END): New macros.
6655 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6675 hard-coding the path separator.
6677 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6679 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6680 This how ASET and AREF are supposed to work, and makes
6681 it easier to think about future improvements. See
6682 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6683 * charset.h (set_charset_attr): New function.

7175 the fix for 12036 would have avoided some of the problems noted in
7176 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7177 would have been more obvious.

7187 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7188 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7189 not be usable in #if. This simplifies things.
7191 2012-07-26 Juanma Barranquero <lekktu@gmail.com>

7200 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7201 Adjust to changes in lisp.h and emacs.c, by using

7211 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7212 (xreload, hook-run, hookpost-run): Remove.
7213 * emacs.c: Include <verify.h>.
7214 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7215 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7217 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7218 (gdb_USE_LSB_TAG): New enum constants.
7219 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

8112 Prefer snprintf to strncpy.
8113 * nsterm.m (ns_term_init):
8114 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8115 * nsterm.m (ns_term_init):
8116 Avoid the need for strncpy, by using build_string or
8117 make_unibyte_string directly. Use dtoastr, not snprintf.
8118 * process.c (Fmake_network_process): Diagnose service names that
8119 are too long, rather than silently truncating them or creating

8150 Optimize pure C strings initialization.
8151 * lisp.h (make_pure_string): Fix prototype.
8152 (build_pure_c_string): New function, defined as static inline. This
8153 provides a better opportunity to optimize away calls to strlen when
8154 the function is called with compile-time constant argument.
8155 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8156 argument, adjust users accordingly. Use build_pure_c_string where
8158 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8159 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8160 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8162 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8164 Avoid calls to strlen in miscellaneous functions.
8165 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8166 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8167 * lread.c (openp): Likewise.
8169 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8171 Avoid calls to strlen in path processing functions.
8172 * fileio.c (file_name_as_directory): Add comment. Change to add
8173 srclen argument and return the length of result. Adjust users
8175 (directory_file_name): Fix comment. Change to add srclen argument,
8176 swap 1st and 2nd arguments to obey the common convention.
8177 Adjust users accordingly.
8178 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8180 2012-07-10 Glenn Morris <rgm@gnu.org>
8182 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
8183 Move PENDING_OUTPUT_COUNT definition to configure.

8187 * s/gnu.h (DATA_START): Move definitions to configure.
8189 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8190 We include usg5-4-common.h, which defines them both.
8192 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8193 O_RDONLY already includes it).
8195 Stop ns builds setting the EMACSLOADPATH environment variable.
8196 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8197 Now it does not set EMACSLOADPATH, just returns the load-path string.
8198 * nsterm.h: Update accordingly.
8199 * lread.c [HAVE_NS]: Include nsterm.h.
8200 (init_lread) [HAVE_NS]: Use ns_load_path.

8203 2012-07-09 Glenn Morris <rgm@gnu.org>
8205 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8206 since the included bsd-common.h does so.
8208 Stop ns builds setting the EMACSPATH environment variable.
8209 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8210 (ns_init_paths): Do not set EMACSPATH.
8211 * nsterm.h (ns_exec_path): Add it.
8212 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8215 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8217 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8219 * process.c (wait_reading_process_output): 'waitchannels' was unset
8220 when read_kbd || !NILP (wait_for_cell); fix this.
8222 Add GCC-style 'const' attribute to functions that can use it.
8223 * character.h (char_resolve_modifier_mask):
8224 * keyboard.h (make_ctrl_char):
8225 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8233 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8234 Add decls with ATTRIBUTE_CONST.
8236 Minor improvements to make_formatted_string.
8237 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8238 where int is good enough, as vsprintf returns an int.
8239 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8241 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8243 Use make_formatted_string to avoid double length calculation.
8244 * lisp.h (make_formatted_string): New prototype.
8245 * alloc.c (make_formatted_string): New function.
8246 * buffer.c (Fgenerate_new_buffer_name): Use it.

8268 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8270 Move marker debugging code under MARKER_DEBUG.
8271 * marker.c (MARKER_DEBUG): Move marker debugging code under
8272 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8273 for bootstrap with --enable-checking (~3x slowdown reported
8274 by Juanma Barranquero <lekktu@gmail.com>).
8275 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8277 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8279 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8280 See <http://bugs.gnu.org/11825#29>.
8282 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8284 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8285 has no font, use the frame's font. (Bug#11813)
8286 (display_line): Add commentary about displaying truncation glyphs
8288 (produce_special_glyphs): Move here from term.c.
8290 * term.c (produce_special_glyphs): Move to xdisp.c.
8292 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8295 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8297 * xdisp.c (display_line): Avoid warning about implicit declaration
8300 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8302 * lisp.h: Remove empty conditional.
8304 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8306 * lread.c (load_path_check): Now static.
8308 Fix some minor --with-ns problems found by static checking.
8309 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8310 (x_set_font) [!HAVE_X_WINDOWS]:
8311 * image.c (xpm_load_image) [HAVE_NS]:
8312 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8313 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8314 Remove unused local.
8315 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8316 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8317 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8318 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8319 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8320 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8321 Fix pointer signedness problem.
8322 * xfaces.c (FRAME_X_FONT_TABLE):
8323 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8325 2012-07-07 Glenn Morris <rgm@gnu.org>
8327 * lread.c (load_path_check): New function, split from init_lread.
8328 (init_lread): Reorganize. Motivation:
8329 If EMACSLOADPATH is set, check/warn about that rather than the
8330 defaults, which we are not going to use. Hence we can remove
8331 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8332 Don't warn if site-lisp directories are missing.
8333 If not installed, start from a blank load-path, since
8334 PATH_LOADSEARCH refers to the eventual installation directories.
8336 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8338 Support truncation and continuation glyphs on GUI frames, when
8339 fringes are disabled. (Bug#11832)
8340 * xdisp.c (init_iterator): Get dimensions of truncation and
8341 continuation glyphs even if on GUI frames.
8342 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8343 or both, are absent.
8344 (start_display, move_it_in_display_line_to): Handle the case of a
8345 GUI frame without a fringe to display continuation or truncation
8347 (insert_left_trunc_glyphs): Support GUI frames: make sure
8348 truncation glyphs overwrite enough glyphs from the current line to
8349 have sufficient space in pixels.
8350 (display_line): Support truncation and continuation glyphs on GUI
8351 frames. If some spare pixels are left on the line after inserting
8352 the truncation glyphs, fill that space with a stretch glyph of a
8353 suitably computed width.
8355 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8356 produce_glyphs, to support GUI sessions.
8358 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8360 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8362 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8364 Do not require float-time's arg to fit in time_t (Bug#11825).
8365 This works better on hosts where time_t is unsigned, and where
8366 float-time is applied to the (negative) difference between two times.
8367 * editfns.c (decode_time_components): Last arg is now double *,
8368 not int *, and means to store all the result as a double, without
8369 worrying about whether the seconds part fits in time_t.
8370 All callers changed.
8371 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8372 All callers changed.
8373 (Ffloat_time): Do not fail merely because the specified time falls
8374 outside of time_t range.
8376 2012-07-07 Glenn Morris <rgm@gnu.org>
8378 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8384 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8385 Update dependencies.
8387 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8389 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

8393 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8394 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8395 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

8398 * xfont.c (compare_font_names): Redo to omit the need for casts.
8400 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8402 * xfns.c (Fx_change_window_property): Doc fix.
8403 * w32fns.c (Fx_change_window_property): Doc fix.
8405 * w32fns.c (Fx_window_property): Accept the same arguments as the
8406 X Windows version. Doc fix.
8407 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8409 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8410 Eli Zaretskii <eliz@gnu.org>
8412 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8413 Windows-specific code from nt/config.nt moved here.
8414 Obsolete settings removed.
8416 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8418 * process.c: Avoid unnecessary calls to gettime.
8419 (wait_reading_process_output): Don't get the time of day
8420 when gobbling data immediately and not waiting, as there's no need
8421 for it in that case. This removes a FIXME.
8423 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8425 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8426 is defined (Bug#11768).
8428 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8430 Fix marker debugging code.
8431 * marker.c (byte_char_debug_check): Do not perform the check
8432 if buffer is not multibyte.
8433 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8434 Call byte_char_debug_check with correct arguments.
8436 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8438 Compile marker debugging code only if ENABLE_CHECKING is defined.
8439 * marker.c (byte_char_debug_check, count_markers):
8440 Use only if ENABLE_CHECKING is defined.
8441 (byte_debug_flag): Remove.
8442 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8443 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8445 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8447 Avoid code repetition in marker-related functions.
8448 * marker.c (attach_marker): New function.
8449 (Fset_marker, set_marker_restricted, set_marker_both)
8450 (set_marker_restricted_both): Use it.
8451 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8452 Consistently rename charno to charpos.
8453 (marker_position): Add eassert.
8454 (marker_byte_position): Convert to eassert.

8473 * window.c (save_window_save): Likewise.
8475 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8477 Do not use Fdelete_overlay in delete_all_overlays
8478 to avoid redundant calls to unchain_overlay.
8479 * buffer.c (drop_overlay): New function.
8480 (delete_all_overlays, Fdelete_overlay): Use it.
8481 * minibuf.c (get_minibuffer): Fix comment.
8483 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8485 Port to OpenBSD 5.1 amd64.
8486 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8487 This is needed for OpenBSD, and should be harmless on all BSD systems.
8488 Also, include <sys/sysctl.h>, as it should be available on all
8489 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8490 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8491 use p_pid member, not kp_proc.pid.
8493 2012-07-06 Glenn Morris <rgm@gnu.org>
8495 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8497 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8499 More xmalloc and related cleanup.
8500 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8501 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

8508 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8510 Omit needless casts involving void * pointers and allocation.
8511 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8512 as the former is more robust if P's type is changed.
8513 Prefer xzalloc to xmalloc + memset 0.
8514 Simplify malloc-or-realloc to realloc.
8515 Don't worry about xmalloc returning a null pointer.
8516 Prefer xstrdup to xmalloc + strcpy.
8517 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8519 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8520 alloca of a constant.
8522 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8524 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8525 hscroll is larger than the line width. Fixes long and futile
8526 looping inside extend_face_to_end_of_line (on a TTY) producing
8527 glyphs that are not needed and thrown away.
8529 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8531 * marker.c (set_marker_restricted_both): Simplify by using

8557 * xdisp.c (window_hscroll_limited): New function.
8558 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8559 coordinates when window's hscroll is set to insanely large
8562 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8564 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8565 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
8567 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

8625 * fileio.c (time_error_value): Check the right error number.
8626 Problem reported by Troels Nielsen in
8627 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8629 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8631 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8632 This should be fixed in a better way; see Eli Zaretskii in
8633 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8634 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8636 * fileio.c (time_error_value): Rename from special_mtime.
8637 The old name's problems were noted by Eli Zaretskii in
8638 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8640 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8641 This variable's comment says Emacs needs at least one GDB-visible
8642 symbol of type enum pvec_type, to work around GDB problems.
8643 The symbol's value doesn't matter.
8645 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8646 that causes compilation to fail on pre-C99 compilers.
8648 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8650 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

8653 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8655 * buffer.c (init_buffer_once): Fix initialization of
8656 headers for buffer_defaults and buffer_local_symbols.
8657 Reported by Juanma Barranquero <lekktu@gmail.com>.
8659 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8661 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8662 * lisp.h (enum pvec_type): Use fewer bits.
8663 (PSEUDOVECTOR_SIZE_BITS): New constant.
8664 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8665 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8666 change in pvec_type.
8667 (PSEUDOVECTOR_TYPEP): New macro.
8668 (TYPED_PSEUDOVECTORP): Use it.
8669 * fns.c (internal_equal): Adapt code to extract pvectype.

8673 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8674 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8675 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8676 abusing vector->header.next.nbytes.
8677 (live_vector_p): Use PVEC_TYPE.
8678 (mark_object): Adapt code to extract pvectype. Use switch.
8680 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8682 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8683 Tighten new eassert a bit.
8685 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8687 Fix compilation with --enable-gcc-warnings and -O1
8689 * doprnt.c (doprnt): Change type of tem to int, initialize
8690 to avoid compiler warning. Add eassert.
8691 * search.c (simple_search): Initialize match_byte to avoid
8692 compiler warning. Add eassert.
8694 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8696 Avoid weird behavior with large horizontal scrolls.
8697 Without this change, for example, large hscroll values would
8698 mess up Emacs's display on Fedora 15 x86, presumably due to
8699 overflows in int calculations in the display code.
8700 Also, if buffers had long lines, Emacs would freeze.
8701 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8702 (set_window_hscroll): New function, containing the old guts of
8703 Fset_window_hscroll. Return the clipped value.
8704 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8705 This avoids the need to check against PTRDIFF_MAX.
8707 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8709 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8711 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8713 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8715 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8716 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8717 since GCC 4.4.6 issues a bogus warning for them.
8719 Fix bugs in file timestamp newness comparisons.
8720 * fileio.c (Ffile_newer_than_file_p):
8721 * lread.c (Fload): Use full timestamp resolution of files,
8722 not just the 1-second resolution, so that files that are only
8723 slightly newer still count as newer.
8724 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8725 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8727 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8729 * fileio.c: Improve handling of file time marker. (Bug#11852)
8730 (special_mtime): New function.
8731 (Finsert_file_contents, Fverify_visited_file_modtime):
8732 Use it to set special mtime values consistently.
8734 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8736 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8737 marker for non-existing file. (Bug#11852)
8739 2012-07-03 Glenn Morris <rgm@gnu.org>
8741 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8742 and did not make it into globals.h).
8744 2012-07-03 Tom Tromey <tromey@redhat.com>
8746 * window.c (Fset_window_margins, Fset_window_fringes)

8782 2012-07-03 Glenn Morris <rgm@gnu.org>
8784 * lisp.h (Frandom): Make it visible to C.
8785 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8786 buffer for invisible buffers. (Bug#1229)

8790 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8791 values which aren't power of 2.
8792 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8793 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8796 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8798 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8800 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8802 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8804 * alloc.c (allocate_vector_block): Remove redundant
8805 calls to mallopt if DOUG_LEA_MALLOC is defined.
8806 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8807 avoid calls to mallopt if zero_vector is returned.
8809 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8811 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8812 is enabled, avoid dereferencing NULL current_sblock if
8815 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8817 Cleanup basic buffer management.
8818 * buffer.h (struct buffer): Change layout to use generic vector
8819 marking code. Fix some comments. Change type of 'clip_changed'
8820 to bitfield. Remove unused #ifndef old.
8821 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8822 (GET_OVERLAYS_AT): Fix indentation.
8823 (for_each_per_buffer_object_at): New macro.

8827 * alloc.c (allocate_buffer): Adjust to match new layout of
8828 struct buffer. Fix comment.
8829 (mark_overlay): New function.

8832 (mark_object): Use it. Adjust marking of misc objects
8833 and related comments.
8835 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8837 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8838 wrapper that is not needed because the wrapped code is a no-op (zero
8839 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8840 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8842 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8844 * alloc.c (mark_buffer): Simplify. Remove prototype.
8845 (mark_object): Add comment. Reorganize marking of vector-like
8846 objects. Use CHECK_LIVE for all vector-like objects except buffers
8847 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8848 Avoid redundant calls to mark_vectorlike for bool vectors.
8850 2012-06-30 Glenn Morris <rgm@gnu.org>
8852 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8854 * epaths.in (PATH_SITELOADSEARCH): New.
8855 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8856 This is rather than relying on --enable-locallisppath elements
8857 having "site-lisp" in their names. (Bug#10208#25, 11658)
8859 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8861 * w32proc.c (sys_select): Accept and ignore one more argument.
8863 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8865 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8866 (pselect) [!MS_DOS]: Redirect to sys_select.
8868 * sysdep.c: Don't include dos.h and dosfns.h.
8870 * process.c (sys_select):
8871 * msdos.c (sys_select): Accept one more argument and ignore it.
8873 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8874 adapt data types and code to that.
8877 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8878 which clashes with the gnulib function of the same name.
8880 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8882 * font.c (font_style_to_value, font_style_symbolic)
8883 (font_prop_validate_style): Add type checks for values in
8886 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8888 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8891 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8893 * xdisp.c (try_window_id): Undo last change.
8895 * w32.c (getwd): Adjust commentary about startup_dir.
8896 (init_environment): Always call sys_access, even in non-MSVC
8897 builds. Don't chdir to the directory of the Emacs executable.
8898 This undoes code from 1997 which was justified by the need to
8899 "avoid conflicts when removing and renaming directories". But its
8900 downside was that every relative file name was being interpreted
8901 relative to the directory of the Emacs executable, which can never
8902 be TRT. In particular, it broke sys_access when called with
8903 relative file names.
8904 (sys_access): Map GetLastError to errno.
8906 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8908 * window.h (struct window): Change type of 'fringes_outside_margins'

8912 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8915 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8917 * gnutls.c (emacs_gnutls_handshake):
8918 Add QUIT to make the loop interruptible.
8920 2012-06-29 Glenn Morris <rgm@gnu.org>
8922 * charset.c (init_charset): Make lack of etc/charsets fatal.
8924 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8926 * editfns.c (region_limit): Fix type mismatch.
8928 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8930 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8931 undefined. Convert from xassert to eassert.
8932 * nsmenu.m: Convert from xassert to eassert.
8933 * nsterm.m: Likewise.
8935 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8937 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8939 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8941 Avoid integer overflow on scroll-left and scroll-right.
8942 * window.c (HSCROLL_MAX): New macro.
8943 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8944 overflow when requested scroll falls outside ptrdiff_t range.
8946 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8948 * window.h (struct window): Change type of 'hscroll',
8949 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8950 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8951 Adjust users accordingly.
8952 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8953 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8954 from EMACS_INT to ptrdiff_t.
8955 (make_window): Omit redundant initialization.
8957 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

8961 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8963 * window.h (struct window): Change type of 'use_time' and
8964 'sequence_number' from Lisp_Object to int.

8974 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8975 adjust comments accordingly.

9030 * alloc.c (allocate_string): Omit intervals initialization.
9031 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9032 as in make_pure_string and make_pure_c_string.

9088 * alloc.c: Remove build_string.
9089 * lisp.h: Define build_string as static inline. This provides
9090 a better opportunity to optimize away calls to strlen when the
9091 function is called with compile-time constant argument.
9092 * image.c (imagemagick_error): Convert to build_string.
9093 * w32proc.c (sys_spawnve): Likewise.
9094 * xterm.c (x_term_init): Likewise.
9096 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9098 Use sprintf return value instead of invoking strlen on result.
9099 In the old days this wasn't portable, since some sprintf
9100 implementations returned char *. But they died out years ago and
9101 Emacs already assumes sprintf returns int.
9102 Similarly for float_to_string.
9103 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9104 * ccl.c (ccl_driver):
9105 * character.c (string_escape_byte8):
9106 * data.c (Fnumber_to_string):

9108 * print.c (print_object):
9109 * xdisp.c (message_dolog):
9110 * xfns.c (syms_of_xfns):
9111 Use sprintf or float_to_string result to avoid need to call strlen.
9112 * data.c (Fnumber_to_string):
9113 Use make_unibyte_string, since the string must be ASCII.
9114 * lisp.h, print.c (float_to_string): Now returns int length.
9115 * term.c (produce_glyphless_glyph):
9116 Use sprintf result rather than recomputing it.
9118 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9119 * Makefile.in (ALL_CFLAGS):
9120 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9121 * gmalloc.c, regex.c: Include <config.h> unconditionally.
9123 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9125 * dispextern.h (xstrcasecmp): Define to library function
9126 strcasecmp if available.
9127 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
9129 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

9142 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9144 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9145 sprintf already null-terminates its output.
9147 * xfns.c (x_window): Remove redundant cast.
9149 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9151 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9152 `const char *' to `char *' to avoid compiler warning.
9154 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9156 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9157 instead of truncating it to 63 (admittedly a generous limit).
9159 * process.c: Fix spelling and caps in comments.
9161 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9163 * emacs.c (setpgrp): Remove definition, unused.

9209 * sound.c (sound_warning, parse_sound):
9210 Remove unnecessary forward decls.
9212 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9214 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
9215 * lisp.h (WAIT_READING_MAX): New macro.
9216 * dispnew.c (Fsleep_for, sit_for):
9217 * keyboard.c (kbd_buffer_get_event):
9218 * process.c (Faccept_process_output):
9219 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9220 This improves on the previous patch, which introduced a bug
9221 when time_t is unsigned and as wide as intmax_t.
9222 See <http://bugs.gnu.org/9000#51>.
9224 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9226 * dispnew.c (sit_for, Fsleep_for):
9227 * keyboard.c (kbd_buffer_get_event):

9240 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9241 Privately reported by Herbert J. Skuhra.
9242 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9244 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9245 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9247 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9249 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9250 last argument of make_unibyte_string.
9252 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9253 language ID in the event parameters.
9255 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9256 event.code, not the obscure "character set ID".
9258 2012-06-23 Chong Yidong <cyd@gnu.org>
9260 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9262 2012-06-23 Eli Zaretskii <eliz@gnu.org>

9279 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9280 Privately reported by Herbert J. Skuhra.
9281 [__FreeBSD__]: Remove "*/" typo after "#include".

9287 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9289 Support higher-resolution time stamps (Bug#9000).
9290 The time stamps are only nanosecond-resolution at the C level,
9291 since that's the best that any real-world system supports now.
9292 But they are picosecond-resolution at the Lisp level, as that's
9293 easy, and leaves room for future OS improvements.
9295 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9298 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9299 Don't get current time unless it's needed.
9301 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9302 now provides it if it's absent.
9303 (start_atimer): Port to higher-res time stamps.
9304 Check for time stamp overflow. Don't get current time more
9305 often than is needed.
9307 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9308 Include systime.h, not time.h.
9309 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9311 * dired.c: Include stat-time.h.
9312 (Ffile-attributes): File times now have higher resolution.
9314 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9315 (struct image): Timestamp now has higher resolution.
9317 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9318 has at least microseconds now. All uses removed.
9319 (update_frame, update_single_window, update_window, update_frame_1)
9320 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9321 (duration_to_sec_usec): Remove; no longer needed.
9323 * editfns.c (time_overflow): Now extern.
9324 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9325 (float-time, Fformat_time_string, Fcurrent_time_string)

9328 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9329 (decode_time_components, lisp_seconds_argument): New functions.
9330 (make_time): Now static.
9331 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9332 Report an error if the time is invalid, rather than having the caller
9335 * fileio.c: Include <stat-time.h>
9336 (Fcopy_file): Copy higher-resolution time stamps.
9337 Prefer to set the time stamp via a file descriptor if that works.

9339 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9340 (Fvisited_file_modtime, Fset_visited_file_modtime):
9341 Support higher-resolution time stamps.
9343 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9345 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9347 * image.c (prepare_image_for_display, clear_image_cache)
9348 (lookup_image): Port to higer-resolution time stamps.
9350 * keyboard.c (start_polling, bind_polling_period):
9351 Check for time stamp overflow.
9352 (read_char, kbd_buffer_get_event, timer_start_idle)
9353 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9354 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9355 Port to higher-resolution time stamps. Do not assume time_t is signed.
9356 (decode_timer): New function. Timers are now vectors of length 9,
9357 not 8, to accommodate the picosecond component.
9358 (timer_check_2): Use it.
9360 * nsterm.m (select_timeout, timeval_subtract): Remove.
9361 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9362 as they're a bit more accurate and handle overflow better.
9363 (ns_select): Change prototype to be compatible with pselect.
9364 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9365 * nsterm.h (ns_select): Adjust prototype.
9367 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9368 us-resolution time stamps.
9369 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9371 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9373 * lisp.h (time_overflow): New decl.
9374 (wait_reading_process_output): First arg is now intmax_t, not int,
9375 to accommodate larger waits.
9377 * process.h (struct Lisp_Process.read_output_delay):
9378 Now counts nanoseconds, not microseconds.
9379 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9381 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9382 (wait_reading_process_output):
9383 Port to ns-resolution time stamps.
9384 (Faccept_process_output, wait_reading_process_output):
9385 Check for time stamp overflow. Do not assume time_t is signed.
9386 (select_wrapper): Remove; we now use pselect.
9387 (Fprocess_attributes): Now generates ns-resolution time stamps.
9389 * sysdep.c: Include utimens.h. Don't include utime.h
9390 or worry about struct utimbuf; gnulib does that for us now.
9391 (gettimeofday): Remove; gnulib provides a substitute.
9392 (make_timeval): New function.
9393 (set_file_times): Now sets ns-resolution time stamps.
9394 New arg FD; all uses changed.
9395 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9396 (system_process_attributes):
9397 Now returns ns-resolution time stamp. All uses changed.
9398 Check for time stamp overflow.
9400 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9401 provides a substitute now.
9403 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9404 since it guarantees struct timespec.
9405 (EMACS_TIME): Now struct timespec, so that we can support
9406 ns-resolution time stamps.
9407 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9408 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9409 (EMACS_USECS): Remove.
9410 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9411 so multiply the arg by 1000 before storing it.
9412 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9414 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9415 Port to ns-resolution time stamps.
9416 (EMACS_TIME_NEG_P): Remove; replaced by....
9417 (EMACS_TIME_SIGN): New macro.
9418 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9419 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

9421 (make_timeval, make_lisp_time, decode_time_components): New decls.
9422 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9423 that it mishandled time_t overflow. You can't compare by subtracting!
9424 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9425 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9427 * term.c: Include <sys/time.h>.
9428 (timeval_to_Time): New function, for proper overflow wraparound.

9433 (Fprimitive_undo): Use them when restoring time stamps.
9435 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9436 (w32_get_internal_run_time):
9437 Port to higher-resolution Emacs time stamps.
9438 (ltime): Now accepts single 64-bit integer, as that's more convenient
9441 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9443 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9444 for compatibility with pselect. Support ns-resolution time stamps.
9446 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9448 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9449 Check for time stamp overflow, and support ns-resolution time stamps.
9451 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9452 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9453 (timeval_subtract): Remove; no longer needed.
9454 (XTflash, XTring_bell, x_wait_for_event):
9455 Port to ns-resolution time stamps. Don't assume time_t is signed.
9457 2012-06-22 Chong Yidong <cyd@gnu.org>

9461 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9463 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9464 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9465 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9466 staticidx goes up to 1597 out of 1600 = 0x640.)
9468 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9470 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9471 Otherwise, the umask might be mistakenly 0 while handling input signals.

9492 (unwind_format_mode_line): Restore them.
9493 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9495 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9496 since tty frames can be explicitly named.
9497 (prepare_menu_bars): Likewise.
9499 * term.c (Ftty_top_frame): New function.
9501 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9503 Port byte-code-meter to modern targets.
9504 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9505 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9506 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9507 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9508 (METER_1, METER_2): Simplify.
9510 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
9512 * data.c (Fdefalias): Return `symbol' (bug#11686).
9514 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9516 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9517 gets killed during executing of this function (Bug#11665).
9518 Try to always return Qt when the buffer has been actually killed.
9519 (Vkill_buffer_query_functions): In doc-string say that functions
9520 run by this hook should not change the current buffer.
9522 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9524 Fix recently-introduced process.c problems found by static checking.
9525 * process.c (write_queue_push, write_queue_pop, send_process):
9526 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
9527 (write_queue_pop): Fix pointer signedness problem.
9528 (send_process): Remove unused local.
9530 2012-06-17 Chong Yidong <cyd@gnu.org>
9532 * xdisp.c (redisplay_internal): No need to redisplay terminal
9533 frames that are not on top.
9535 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
9537 * process.c (make_process): Initialize write_queue.
9538 (write_queue_push, write_queue_pop): New functions.

9542 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>

9739 as the union type is for debugging, not for production.
9740 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9741 Use an inline function on all platforms when using the union type,
9742 since this is simpler and 'static inline' can be used portably

9886 * doprnt.c (doprnt): Truncate multibyte char correctly.
9887 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9888 would mishandle a string argument "Xc" if X was a multibyte
9889 character of length 2: it would truncate after X's first byte
9890 rather than including all of X.

9973 and 'double' in a couple of places.
9975 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9977 * xdisp.c (handle_stop): Detect whether we have overlay strings
9978 loaded by testing it->current.overlay_string_index to be
9979 non-negative, instead of checking whether n_overlay_strings is
9980 positive. (Bug#11587)

9997 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9998 for the duration of call to load_charset, to avoid problems with
9999 callers of maybe_unify_char that access buffer text through C
10002 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10003 decrement the inhibition flag, instead of just setting or

10009 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

10023 * emacs.c: Include <sys/gmon.h> when profiling.
10024 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10025 (__executable_start): Remove decl, since lisp.h does it now.
10026 (safe_bcopy): Remove decl; no longer has that name.
10027 (main): Coalesce #if into single bit of code, for simplicity.
10028 Cast pointers to uintptr_t, since standard libraries want integers
10030 * lisp.h (__executable_start): New decl.
10032 2012-05-31 Glenn Morris <rgm@gnu.org>
10034 * image.c (Fimagemagick_types): Doc fix.

10057 Do not create empty overlays with the evaporate property (Bug#9642).
10058 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10059 Bug#9642, but explicitly check that the buffer the overlay would
10060 be moved to is live and rearrange lines to make sure that errors
10061 will not put the overlay in an inconsistent state.
10062 (Fdelete_overlay): Cosmetics.
10064 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10066 * w32term.c (my_bring_window_to_top): New function.
10067 (x_raise_frame): Use handle returned by DeferWindowPos, which
10068 could be different from the original one.

10078 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10080 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10081 This avoids undefined behavior that might cause the eassert
10082 to not catch an out-of-range value.
10084 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10086 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10087 Update dependencies.
10089 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10091 * bidi.c (bidi_mirror_char): Fix last change.
10093 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

10096 when referring to sectname field in printf format.
10098 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10100 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10101 Only r_alloc_inhibit_buffer_relocation needed to be added;
10102 the others were already declared.
10104 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10105 before checking whether it's out of range. Put the check inside
10107 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10109 2012-05-27 Ken Brown <kbrown@cornell.edu>
10111 * callproc.c (Fcall_process): Restore a line that was accidentally
10112 commented out in the 2011-02-13 change (bug#11547).
10114 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10116 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10117 defined on ralloc.c.
10119 * buffer.c [REL_ALLOC]: Remove prototypes of
10120 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10121 they are now on lisp.h.
10123 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10125 * search.c (search_buffer): Use it to inhibit relocation of buffer
10126 text while re_search_2 is doing its job, because re_search_2 is
10127 passed C pointers to buffer text. (Bug#11519)
10129 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10130 Update value to 24.
10132 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10133 state after an additional call to move_it_in_display_line_to, keep
10134 the values of it->max_ascent and it->max_descent found for the
10136 (pos_visible_p): Revert the comparison against bottom_y to what it
10137 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10140 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10142 Fix coding-related core dumps with gcc -ftrapv.
10143 The code was computing A - B, where A and B are pointers, and B is
10144 random garbage. This can lead to core dumps on platforms that
10145 have special pointer registers, and it also leads to core dumps on
10146 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10147 A - B only when B is initialized properly.
10148 * coding.c (coding_set_source, coding_set_destination): Return void.
10149 (coding_change_source, coding_change_destinations): New functions,
10150 with the old behaviors of coding_set_source and coding_set_destination.
10151 All callers that need an offset changed to use these new functions.
10153 2012-05-26 Glenn Morris <rgm@gnu.org>
10155 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10157 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10159 Extend mouse support on W32 text-mode console.
10160 * xdisp.c (draw_row_with_mouse_face):
10161 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10163 * w32console.c: Include window.h.
10164 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10166 (initialize_w32_display): Initialize mouse-highlight data.
10168 * w32inevt.c: Include termchar.h and window.h.
10169 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10170 moves, call note_mouse_highlight. If help_echo changed, call
10171 gen_help_event to produce help-echo message in the echo area.
10172 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10175 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10177 * lread.c (read1): Simplify slightly to avoid an overflow warning
10178 with GCC 4.7.0 on x86-64.
10180 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10182 * bidi.c (bidi_mirror_char): Revert last change: an int is
10183 definitely wide enough here.
10185 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10187 Fix integer width and related bugs (Bug#9874).

10197 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10198 (allocate_pseudovector):
10199 Use int, not EMACS_INT, where int is wide enough.
10200 (inhibit_garbage_collection, Fgarbage_collect):
10201 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10202 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10203 int might not be wide enough.
10204 (bidi_cache_search, bidi_cache_find, bidi_init_it)

10219 (Foverlay_recenter, last_overlay_modification_hooks_used)
10220 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10221 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10222 (validate_region): Omit unnecessary test for b <= e,
10223 since that's guaranteed by the previous test.
10224 (adjust_overlays_for_delete): Avoid pos + length overflow.
10225 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10226 (report_overlay_modification):
10227 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10228 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10229 Omit pointer cast, which isn't needed anyway, and doesn't work
10230 after the EMACS_INT -> ptrdiff_t change.
10231 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10232 * buffer.h: Adjust decls to match defn changes elsewhere.
10233 (struct buffer_text, struct buffer):
10234 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10235 Use EMACS_INT, not int, where int might not be wide enough.
10236 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10237 not int, to avoid needless 32-bit limit on 64-bit hosts.
10238 (exec_byte_code): Use tighter memory-full test, one that checks
10239 for alloca overflow. Don't compute the address of the object just
10240 before an array, as that's not portable. Use EMACS_INT, not
10241 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10242 * callint.c (Fcall_interactively):
10243 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10244 * callproc.c (call_process_kill, Fcall_process):
10245 Don't assume pid_t fits into an Emacs fixnum.
10246 (call_process_cleanup, Fcall_process, child_setup):

10250 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10251 (Fcall_process): Simplify handling of volatile integers.

10254 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10255 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10256 (casify_object): Avoid integer overflow when overallocating buffer.
10257 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10258 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10259 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10260 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10261 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10262 integers are now checked earlier. All uses replaced with XINT.
10264 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10265 For CCL_MapSingle, check that content and value are in int range.
10266 (ccl_driver, Fregister_code_conversion_map):
10267 Check that Vcode_version_map_vector is a vector.
10268 (resolve_symbol_ccl_program): Check that vector header is in range.
10269 Always copy the vector, so that we can check its contents reliably
10270 now rather than having to recheck each instruction as it's being
10271 executed. Check that vector words fit in 'int'.
10272 (ccl_get_compiled_code, Fregister_ccl_program)
10273 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10274 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10275 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10276 contents are in range.
10277 (Fccl_execute_on_string): Check that status is in range.
10278 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10279 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10280 Accept and return EMACS_INT, not int, because callers can pass values
10281 out of 'int' range.

10283 (multibyte_chars_in_text, parse_str_as_multibyte)

10287 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10288 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10289 avoid mishandling large integers.
10290 * character.h: Adjust decls to match defn changes elsewhere.
10291 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10292 (Ffind_charset_region):
10293 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

10296 Don't assume fixnum fits in int.
10297 (load_charset_map_from_vector, Fmap_charset_chars):
10298 Remove now-unnecessary CHECK_NATNUMs.
10299 (Fdefine_charset_internal): Check ranges here, more carefully.
10300 Don't rely on undefined behavior with signed left shift overflow.
10301 Don't assume unsigned int fits into fixnum, or that fixnum fits
10302 into unsigned int. Don't require max_code to be a valid fixnum;
10303 that's not true for gb10830 4-byte on a 32-bit host. Allow
10304 invalid_code to be a cons, for the same reason. Require code_offset
10305 to be a character. Avoid int overflow if max_char is close
10307 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10308 this is intended anyway and avoids some undefined behavior.
10309 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10310 INDEX_TO_CODE_POINT, as that's what it expects.
10311 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10312 * charset.h (DECODE_CHAR): Return int, not unsigned;
10313 this is what was intended anyway, and it avoids undefined behavior.
10314 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10315 integer-overflow issues.
10316 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10317 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10318 where the argument is EMACS_INT, and this behavior is not intended.
10319 * chartab.c (Fmake_char_table, Fset_char_table_range)
10320 (uniprop_get_decoder, uniprop_get_encoder):
10321 Don't assume fixnum fits in int.
10322 * cmds.c (move_point): New function, that does the gist of
10323 Fforward_char and Fbackward_char, but does so while checking
10324 for integer overflow more accurately.
10325 (Fforward_char, Fbackward_char): Use it.
10326 (Fforward_line, Fend_of_line, internal_self_insert)
10327 (internal_self_insert):
10328 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10363 (consume_chars): Rewrite to not calculate an address outside buffer.
10364 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10365 Don't access memory outside of the args array.
10366 (Fdefine_coding_system_internal): Check for charset-id overflow.
10367 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10368 result of ENCODE_CHAR.
10369 * coding.h: Adjust decls to match defn changes elsewhere.
10370 (struct coding_system):

10387 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
10388 Do not attempt to compute the address of the object just before a
10389 buffer; this is not portable.
10391 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11094 2012-05-17 Juri Linkov <juri@jurta.org>
11096 * search.c (Fword_search_regexp, Fword_search_backward)
11097 (Fword_search_forward, Fword_search_backward_lax)
11098 (Fword_search_forward_lax): Move functions to isearch.el
11099 (bug#10145, bug#11381).
11101 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11103 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11105 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11107 * lread.c (init_obarray): Declare Qt and Qnil as special.
11109 2012-05-14 Glenn Morris <rgm@gnu.org>
11111 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11112 Put "libexec" before "bin", for the sake of init_callproc_1.
11114 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11116 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11118 * unexaix.c: Port to more-recent AIX compilers.
11119 (report_error, report_error_1, make_hdr, copy_sym)
11120 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11121 Make arguments const char *, not char *, to avoid violations of C
11122 standard and to fix some AIX warnings reported by Gilles Pion.
11124 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11126 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11127 already have overlays loaded.
11128 (handle_single_display_spec): Before returning without displaying
11129 fringe bitmap, synchronize the bidi iterator with the main display
11130 iterator, by calling iterate_out_of_display_property.
11131 (iterate_out_of_display_property): Detect buffer iteration by
11132 testing that it->string is a Lisp string.
11133 (get_next_display_element): When the current object is exhausted,
11134 and there's something on it->stack, call set_iterator_to_next to
11135 proceed with what's on the stack, instead of returning zero.
11136 (set_iterator_to_next): If called at the end of a Lisp string,
11137 proceed to consider_string_end without incrementing string
11138 position. Don't increment display vector index past the end of
11139 the display vector. (Bug#11417)
11140 (pos_visible_p): Don't report a position visible when move_it_to
11141 stopped at the last line of window, which happens to be scanned
11142 backwards by the bidi iteration. (Bug#11464)
11144 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11146 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11147 and right-margin display specs even if the spec is invalid or we
11148 are on a TTY, and thus unable to display on the fringes.
11149 That's because the text with the property will not be displayed anyway,
11150 so we need to signal to the caller that this is a "replacing"
11151 display spec. This fixes display when the spec is invalid or we
11154 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11156 * unexaix.c (make_hdr): Fix typo in prototype.
11157 This bug broke the build on AIX. Problem reported by Gilles Pion.
11159 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11161 * keyboard.c (kbd_buffer_get_event): Read special events also in
11162 batch mode. (Bug#11415)
11164 2012-05-12 Glenn Morris <rgm@gnu.org>
11166 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11168 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11170 * lisp.mk (lisp): Add newcomment.elc.
11172 2012-05-12 Glenn Morris <rgm@gnu.org>
11174 * Makefile.in (MKDIR_P): New, set by configure.
11175 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11177 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11179 Remove unused function hourglass_started.
11180 * dispextern.h (hourglass_started):
11181 * w32fns.c (hourglass_started):
11182 * xdisp.c (hourglass_started): Remove.
11184 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11186 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11187 Update dependencies.
11189 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11191 * xgselect.c (xg_select): Put maxfds+1 into a var.
11192 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11194 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11196 2012-05-10 Dave Abrahams <dave@boostpro.com>
11198 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11199 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11201 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11203 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11204 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11205 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11206 Initialize xd_registered_buses.
11208 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11210 Untag more efficiently if USE_LSB_TAG.
11211 This is based on a proposal by YAMAMOTO Mitsuharu in
11212 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11213 For an admittedly artificial (nth 8000 longlist) benchmark on
11214 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11215 Emacs's overall text size by 1%.
11216 * lisp.h (XUNTAG): New macro.
11217 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11218 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11219 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11220 * eval.c (Fautoload):
11221 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11222 * frame.h (XFRAME): Use XUNTAG.
11224 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11225 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11226 Remove unportable assumptions about print widths of types like
11228 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11229 intptr_t when converting between pointer and integer, to avoid GCC
11230 warnings about wrong width.
11232 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11234 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11235 stack for each reader_thread, instead of defaulting to 8MB
11236 determined by the linker. This avoids failures in creating
11237 subprocesses on Windows 7, see the discussion in this thread:
11238 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11240 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11242 Fix up display of the *Minibuf-0* buffer in the mini window.
11243 * keyboard.c (read_char): Don't clear the echo area if there's no
11245 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11246 contents of *Minibuf-0*) if there's no message displayed in its stead.
11248 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11250 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11253 2012-05-06 Chong Yidong <cyd@gnu.org>
11255 * lisp.mk (lisp): Update.
11257 2012-05-05 Jim Meyering <meyering@redhat.com>
11259 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11261 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11263 * data.c (PUT_ERROR): New macro.
11264 (syms_of_data): Use it. Add new error type `user-error'.
11265 * undo.c (user_error): New function.
11266 (Fprimitive_undo): Use it.
11267 * print.c (print_error_message): Adjust print style for `user-error'.
11268 * keyboard.c (user_error): New function.
11269 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11271 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11273 Do not limit current-time-string to years 1000..9999.
11274 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11275 (Fcurrent_time_string): Support any year that is supported by the
11276 underlying localtime representation. Don't use asctime, as it
11277 has undefined behavior for years outside the range -999..9999.
11279 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11281 Fix race conditions involving setenv, gmtime, localtime, asctime.
11282 Without this fix, interrupts could mess up code that uses these
11283 nonreentrant functions, since setting TZ invalidates existing
11284 tm_zone or tzname values, and since most of these functions return
11285 pointers to static storage.
11286 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11287 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11288 Grow the critical sections to include not just invoking
11289 localtime/gmtime, but also accessing these functions' results
11290 including their tm_zone values if any, and any related TZ setting.
11291 (format_time_string): Last arg is now struct tm *, not struct tm **,
11292 so that the struct tm is saved in the critical section.
11293 All callers changed. Simplify allocation of initial buffer, partly
11294 motivated by the fact that memory allocation needs to be outside
11295 the critical section.
11297 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11299 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11300 with RESET_INTERVAL.
11302 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11303 Remove duplicated buffer name initialization.
11305 2012-05-02 Jim Meyering <jim@meyering.net>
11307 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11309 * xfns.c (x_window): Use xstrdup (Bug#11375).
11311 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11313 * xdisp.c (pos_visible_p): If already at a newline from the
11314 display string before the 'while' loop, don't walk back the glyphs
11315 from it3.glyph_row. Solves assertion violation when the display
11316 string begins with a newline (egg.el). (Bug#11367)
11318 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11320 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11323 2012-05-01 Glenn Morris <rgm@gnu.org>
11325 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11326 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11327 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11328 All were removed before 23.1.
11330 * dispnew.c: Remove HAVE_LIBNCURSES test;
11331 it is always true on relevant platforms.
11333 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11334 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11336 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11338 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11340 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11341 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11344 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11346 Do not avoid creating empty evaporating overlays (Bug#9642).
11347 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11348 That is, do not delete an evaporating overlay if it becomes
11349 empty after its bounds are adjusted to fit within its buffer.
11350 This fix caused other problems, and I'm reverting it until we get
11351 to the bottom of them.
11353 2012-04-27 Chong Yidong <cyd@gnu.org>
11355 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11357 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11359 * xdisp.c (pos_visible_p): If the window start position is beyond
11360 ZV, start the display from buffer beginning. Prevents assertion
11361 violation in init_iterator when the minibuffer window is scrolled
11362 via the scroll bar.
11364 * window.c (window_scroll_pixel_based): Likewise.
11366 2012-04-27 Chong Yidong <cyd@gnu.org>
11368 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11370 2012-04-27 Glenn Morris <rgm@gnu.org>
11372 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11373 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11375 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11377 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11378 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11380 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11382 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11383 display element, check also the underlying string or buffer
11384 character. (Bug#11341)
11386 * w32menu.c: Include w32heap.h.
11387 (add_menu_item): If the call to AppendMenuW (via
11388 unicode_append_menu) fails, disable Unicode menus only if we are
11389 running on Windows 9X/Me.
11391 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11393 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11394 (xgetint): Add missing shift for LSB tags.
11396 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11398 * keyboard.c (read_char): Don't wipe echo area for select window
11399 events: These might get delayed via `mouse-autoselect-window'
11402 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11404 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11405 manipulation of :loaded-from data.
11407 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11409 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11410 now a cons (bug#11311).
11412 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11414 Do not create empty overlays with the evaporate property (Bug#9642).
11415 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11416 if it becomes empty after its bounds are adjusted to fit within
11417 its buffer. Without this fix, in a nonempty buffer (let ((o
11418 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11419 yields an empty overlay that has the evaporate property, which is
11420 not supposed to happen.
11422 Fix minor GTK3 problems found by static checking.
11423 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11424 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11425 (struct _EmacsFixedClass, emacs_fixed_get_type):
11426 Move decls here from emacsgtkfixed.h, since they needn't be public.
11427 (emacs_fixed_get_type): Now static.
11428 (emacs_fixed_class_init): Omit unused local.
11429 (emacs_fixed_child_type): Remove; unused.
11430 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11431 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11432 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11433 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11434 (EMACS_FIXED_GET_CLASS): Remove; unused.
11435 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11437 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11438 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11440 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11442 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11443 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11444 (__malloc_size_t, __malloc_ptrdiff_t):
11445 Remove. All uses removed, replaced by the definiens if needed,
11446 since we can assume C89 or better now.
11447 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11455 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11456 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11457 Define using prototypes, not old style.
11458 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11459 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11460 (align): Don't assume that signed integer overflow wraps around.
11461 Omit unused local var.
11462 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11463 (_free_internal_nolock, memalign, mallochook, reallochook):
11464 Omit no-longer-needed casts.
11465 (valloc): Use getpagesize, not __getpagesize.
11466 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11467 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11469 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11471 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11473 Move functions from C to Lisp. Make non-blocking method calls
11474 the default. Implement further D-Bus standard interfaces.
11476 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

11492 (xd_signature, xd_append_arg): Allow float for integer types.
11493 (xd_get_connection_references): New function.
11494 (xd_get_connection_address): Rename from xd_initialize.
11495 Return cached address.
11496 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
11497 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp
11499 (Fdbus_init_bus): New optional arg PRIVATE. Cache address.
11500 Return number of refcounts.
11501 (Fdbus_get_unique_name): Make stronger parameter check.

11516 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11518 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
11519 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
11520 Do not assume ptrdiff_t is the same width as 'int'.
11522 * alloc.c: Handle unusual debugging option combinations.
11523 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
11524 since the two debugging options are incompatible.
11525 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

11535 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11537 * sysdep.c [__FreeBSD__]: Minor cleanups.
11538 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11539 Use Emacs indenting style more consistently. Avoid some casts.
11540 Use 'double' consistently rather than mixing 'float' and 'double'.
11542 2012-04-21 Eduard Wiebe <usenet@pusto.de>
11544 * sysdep.c (list_system_processes, system_process_attributes):
11545 Add implementation for FreeBSD (Bug#5243).

11551 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11553 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11554 It is never used otherwise.
11556 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11558 * print.c (print_preprocess): Only check print_depth if print-circle
11560 (print_object): Check for cycles even when print-circle is nil and
11561 print-gensym is t, but only check print_depth if print-circle is nil.
11563 2012-04-20 Chong Yidong <cyd@gnu.org>
11565 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11566 set the status to "failed" and ensure that sentinel is run.
11568 2012-04-20 Glenn Morris <rgm@gnu.org>
11570 * process.c (Fset_process_inherit_coding_system_flag)
11571 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

11579 row, return zero immediately.
11580 (try_cursor_movement): If inside continuation line, don't back up
11581 farther than the first row after the header line, if any.
11582 Don't consider the header-line row as "partially visible", even if
11583 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
11585 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11587 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"

11594 * Makefile.in (C_WARNINGS_SWITCH): Remove.
11595 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
11596 (ALL_CFLAGS): Use new macros rather than old.
11597 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.

11599 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11600 -Wunused-result, -Wunused-variable. This should go away once
11601 the Emacs and Gnulib regex code is merged.
11602 (xmalloc, xrealloc): Now static.
11604 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

11621 New extern decls, to avoid calling undeclared functions.
11622 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11623 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11624 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11625 (NEED_MEM_INSERT): New macro.
11626 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11627 Remove one incorrect comment and fix another.

11641 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
11642 Remove decls. This fixes an "It stinks!".
11644 * alloc.c (which_symbols): Fix alignment issue / type clash.
11646 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11648 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11649 (struct Lisp_Misc_Any): Likewise.
11650 (struct Lisp_Free): Likewise.
11651 * alloc.c (union aligned_Lisp_Symbol): Define.

11659 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
11661 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
11662 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
11663 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11664 * s/netbsd.h, s/sol2-6.h:
11665 Remove definition of GC_MARK_STACK, since the default now works.
11666 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11667 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11668 no longer the default.
11669 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11671 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11673 * lread.c (lisp_file_lexically_bound_p):
11674 Fix hang at ";-*-\n" (bug#11238).
11676 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11678 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
11679 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

11688 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
11690 2012-04-13 Reuben Thomas <rrt@sc3d.org>
11692 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11694 2012-04-11 Daniel Colascione <dancol@dancol.org>
11696 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11697 against is gone. It's better to use vfork now so that when Cygwin
11698 gains a new, working vfork, we use it automatically (bug#10398).
11700 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11702 * window.c (save_window_save): Obey window-point-insertion-type.

11718 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
11720 * w32.c (w32_delayed_load): Record the full path of the library
11721 being loaded (bug#10424).
11723 2012-04-09 Glenn Morris <rgm@gnu.org>
11725 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11726 not just in the obarray, before snarfing them. (Bug#11036)

11729 Pass EMACS rather than BUILT_EMACS.
11731 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
11733 * process.c (make_process):
11734 * process.h: Add integer `gnutls_handshakes_tried' member to
11737 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.

11743 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11744 attempts per process (connection).
11746 2012-04-09 Chong Yidong <cyd@gnu.org>
11748 * eval.c (Fuser_variable_p, user_variable_p_eh)
11749 (lisp_indirect_variable): Functions deleted.
11750 (Fdefvar): Caller changed.
11752 * callint.c (Finteractive, Fcall_interactively):
11753 * minibuf.c (Fread_variable): Callers changed.
11755 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11757 * xdisp.c (set_cursor_from_row): If the display string appears in
11758 the buffer at position that is closer to point than the position
11759 after the display string, display the cursor on the first glyph of
11760 the display string. Fixes cursor display when a 'display' text
11761 property immediately follows invisible text. (Bug#11094)
11763 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11765 composite.c: use 'double' consistently
11766 * composite.c (get_composition_id): Use 'double' consistently
11767 instead of converting 'float' to 'double' and vice versa; this is
11768 easier to understand and avoids a GCC warning.
11770 2012-04-09 Glenn Morris <rgm@gnu.org>
11772 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11773 preparation for dumping it with emacs. (Bug#4789)
11774 (leimdir): New variable.

11794 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11795 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11796 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11797 objects, as mark_maybe_pointer will catch them otherwise.
11798 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11799 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

11806 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11808 Support building on MS-Windows with libxml2.
11810 * makefile.w32-in (OBJ2): Add xml.$(O).
11811 (GLOBAL_SOURCES): Add xml.c.
11812 ($(BLD)/xml.$(O)): New dependency list.
11814 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11815 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11816 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11817 [!WINDOWSNT]: New macros.
11818 (init_libxml2_functions, libxml2_loaded_p): New functions.
11819 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11820 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11821 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11822 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11824 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11825 Call init_libxml2_functions before calling libxml2 functions.
11826 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11828 * emacs.c: Don't include libxml/parser.h.
11829 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11830 xmlCleanupParser directly.
11832 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11834 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11836 * indent.c (Fvertical_motion): If there is a display string at
11837 point, use it.vpos to compute how many lines to backtrack after
11838 move_it_to point. (Bug#11133)
11840 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11842 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11843 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11844 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11845 macros related to unification of CJK characters. For the details,
11846 see the discussion following the message here:
11847 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11849 2012-04-04 Chong Yidong <cyd@gnu.org>
11851 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11853 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11855 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
11856 instead of alloca. (Bug#11138)
11858 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
11860 * w32menu.c (is_simple_dialog): Properly check lisp types.
11863 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11865 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11866 position we get to after a call to move_it_to fails the
11867 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11868 only if we wind up in a string from display property. (Bug#11063)
11870 * window.c (Fdelete_other_windows_internal): Invalidate the row
11871 and column information about mouse highlight, so that redisplay
11872 restores it after reallocating the glyph matrices. (Bug#7464)
11874 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11875 string comes from a `display' text property, use the buffer
11876 position of that property as if we actually saw that position in
11878 (move_it_by_lines): Remove the assertion that
11879 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11880 violated when there's a before-string at the beginning of a line.
11883 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11885 * xdisp.c (append_space_for_newline): If the default face was
11886 remapped, use the remapped face for the appended newline.
11887 (extend_face_to_end_of_line): Use the remapped default face for
11888 extending the face to the end of the line.
11889 (display_line): Call extend_face_to_end_of_line when the default
11890 face was remapped. (Bug#11068)
11892 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11894 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11896 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
11898 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
11900 2012-03-27 Glenn Morris <rgm@gnu.org>
11902 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11905 2012-03-26 Kenichi Handa <handa@m17n.org>

11912 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11913 (command_loop_1): Use it; inhibit selection update for
11914 handle-select-window too (Bug#8996).

11918 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11920 2012-03-25 Kenichi Handa <handa@m17n.org>
11922 * dispextern.h (struct glyph): Change the bit length of
11923 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11925 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11927 * s/ms-w32.h (tzname): Include time.h before redirecting to
11928 _tzname. Fixes the MSVC build. (Bug#9960)
11930 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
11932 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11935 * xterm.c (XTread_socket): Only modify handling_signal if
11936 !SYNC_INPUT. (Bug#11080)
11938 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11940 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11941 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11942 when fetching a multibyte character consumes more bytes than
11943 CHAR_BYTES returns, due to unification of CJK characters in
11944 string_char. (Bug#11073)
11946 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11948 * process.c (wait_reading_process_output): Handle pty disconnect
11949 by refraining from sending oneself a SIGCHLD (bug#10933).
11951 2012-03-22 Chong Yidong <cyd@gnu.org>
11953 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11955 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11956 Mark string as coming from a prefix property.
11957 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11958 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11960 2012-03-21 Chong Yidong <cyd@gnu.org>
11962 * xfaces.c (Vface_remapping_alist): Doc fix.
11964 2012-03-20 Eli Zaretskii <eliz@gnu.org>
11966 * w32proc.c (Fw32_set_console_codepage)
11967 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

11978 it fit in a valid range (Bug#11003).
11980 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11982 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11983 that is not from display property, accept the row as a "cursor
11984 row" if one of the string's character has a non-nil `cursor'
11985 property. Fixes cursor positioning when there are newlines in
11986 overlay strings, e.g. in icomplete.el. (Bug#11035)
11988 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

12019 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12022 2012-03-03 Glenn Morris <rgm@gnu.org>
12024 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12026 2012-03-02 Eli Zaretskii <eliz@gnu.org>

12029 position past the first glyph_row that ends at ZV. (Bug#10902)
12030 (redisplay_window, next_element_from_string): Fix typos in
12032 (redisplay_window): Pass to move_it_vertically the margin in

12037 * buffer.c (buffer-list-update-hook): Doc fix.
12039 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12041 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12042 push_it before setting up the iterator for the first overlay
12043 string, even if we have an empty string loaded.
12044 (next_overlay_string): If there's an empty string on the iterator
12045 stack, pop the stack. (Bug#10903)
12047 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12049 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12050 Suggested by Stefan Monnier in
12051 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12052 * alloc.c (widen_to_Lisp_Object): New static function.
12053 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12054 and widening them to Lisp_Objects. This would work even if
12055 USE_LSB_TAG is defined and wide integers are used, which might
12056 happen in a future version of Emacs.
12058 2012-02-25 Chong Yidong <cyd@gnu.org>
12060 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12069 * keyboard.c (process_special_events): Handle all X selection
12070 requests in kbd_buffer, not just the next one (Bug#8869).
12072 2012-02-23 Chong Yidong <cyd@gnu.org>
12074 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12075 call when setting menu-bar-lines and tool-bar-lines parameters.
12076 (unwind_create_frame_1): New helper function.
12078 * window.c (inhibit_window_configuration_change_hook): New var.

12097 when computing $valmask.
12099 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12100 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12101 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12102 It's useless in that case, and it can cause problems on hosts
12103 that allocate halves of EMACS_INT values separately.
12104 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12105 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12106 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12107 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12108 it avoids undefined behavior on hosts where shifting right by more
12109 than the word width has undefined behavior.
12111 2012-02-19 Chong Yidong <cyd@gnu.org>
12113 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12114 (Funhandled_file_name_directory, Ffile_name_as_directory)

12116 (Fsubstitute_in_file_name): Protect against invalid file handler
12117 return values (Bug#10845).

12133 2012-02-15 Chong Yidong <cyd@gnu.org>
12135 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

12151 2012-02-12 Chong Yidong <cyd@gnu.org>
12153 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12154 as that creates a dangerous corner case.
12156 * window.c (Fdelete_window_internal): Invalidate the mouse
12157 highlight (Bug#9904).
12159 2012-02-12 Glenn Morris <rgm@gnu.org>

12189 2012-02-07 Chong Yidong <cyd@gnu.org>
12191 * buffer.c (Fbuffer_local_variables)
12192 (buffer_lisp_local_variables): Handle unbound vars correctly;
12193 don't let Qunbound leak into Lisp.
12195 2012-02-07 Glenn Morris <rgm@gnu.org>
12197 * image.c (Fimagemagick_types): Doc fix.
12199 * image.c (imagemagick-render-type): Change it from a lisp object
12200 to an integer. Move the doc here from the lisp manual.

12230 before BEGV. (Bug#10696)
12232 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12234 Handle overflow when computing char display width (Bug#9496).
12235 * character.c (char_width): Return EMACS_INT, not int.
12236 (char_width, c_string_width): Check for overflow when
12237 computing the width; this is possible now that individual
12238 characters can have unbounded width. Problem introduced
12239 by merge from Emacs 23 on 2012-01-19.

12263 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12265 (x_produce_glyphs): If the component of a composition is a null

12270 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12271 first 2 arguments are identical. This makes inserting large
12272 output from a subprocess an order of magnitude faster on
12273 MS-Windows, where all sbrk'ed memory is always contiguous.

12373 DISP_STRING, and accept any glyph in a row whose object is that
12374 string as eligible for mouse highlight. Fixes mouse highlight of
12375 display strings from overlays. (Bug#10464)
12377 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
12379 emacs: fix an auto-save permissions race condition (Bug#10400)

12381 (Fmake_directory_internal): Use it.

12892 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12893 is set, removing the need for VIRT_ADDRESS_VARIES.
12894 (PURE_P): Use a more-efficient implementation that needs just one

12897 to 4 (xorl, subq, cmpq, setbe).
12898 * alloc.c (pure): Always extern now, since that's the

12909 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12910 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12911 behave as if the cursor position were at the window margin.
12913 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12914 and the cursor position is out of bounds, behave as if the cursor
12915 position were at the window margin. (Bug#10075)
12917 2011-11-18 Chong Yidong <cyd@gnu.org>
12919 * window.c (Fwindow_combination_limit): Make first argument

12992 Fixes assertion violations in row_equal_p. (Bug#10035)
12994 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

13143 static_offset_intervals. The old version didn't conform to C99
13144 because an extern inline function contained a reference to an

13395 2011-10-27 Chong Yidong <cyd@gnu.org>
13397 * process.c (make_process): Set gnutls_state to NULL.
13399 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13400 non-NULL, regardless of GNUTLS_INITSTAGE.
13401 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13402 an error. Set process slots as soon as we allocate them.
13404 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13406 2011-10-27 Chong Yidong <cyd@gnu.org>
13408 * gnutls.c (emacs_gnutls_deinit): New function.
13409 Deallocate credentials structures as well as calling gnutls_deinit.
13410 (Fgnutls_deinit, Fgnutls_boot): Use it.
13412 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13413 (deactivate_process): Call emacs_gnutls_deinit.
13415 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13417 * image.c (x_create_x_image_and_pixmap):
13418 * w32.c (sys_rename, w32_delayed_load):
13419 * w32font.c (fill_in_logfont):
13420 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13422 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13424 * w32fns.c (w32_default_color_map): New function,
13425 extracted from Fw32_default_color_map.
13426 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13428 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13430 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13432 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13434 * keyboard.c (test_undefined): New function (bug#9751).
13435 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13437 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13439 * sysdep.c (init_sys_modes): Fix the check for the controlling
13440 terminal (Bug#6649).
13442 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13444 * dispextern.h (struct bidi_it): New member next_en_type.
13446 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13447 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13448 current character, check also for next_en_type being WEAK_EN.
13449 (bidi_resolve_weak): Don't enter the expensive loop if the current
13450 position is before next_en_pos. Record the bidi type of the first
13451 non-ET, non-BN character we find, in addition to its position.
13452 (bidi_level_of_next_char): Invalidate next_en_type when
13453 next_en_pos is over-stepped.
13455 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13457 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13458 * editfns.c: Rewrite current-time-zone so that it invokes
13459 the equivalent of (format-time-string "%Z") to get the time zone name.
13460 This fixes a bug when the time zone name contains characters that
13461 need converting from the system time locale to Emacs internal format.
13462 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13463 that patch fixed format-time-string to do the conversion, but
13464 I forgot to fix current-time-zone.
13465 (format_time_string): New function, containing most of
13466 what Fformat_time_string used to contain.
13467 (Fformat_time_string): Rewrite in terms of format_time_string.
13468 This doesn't change this function's behavior.
13469 (current-time-zone): Rewrite to use format_time_string.
13470 This fixes the bug reported by Michael Schierl in
13471 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13472 Jason Rumney's 2007-06-07 change worked around this bug, but
13474 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13476 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13478 * xdisp.c (start_display): If the character at POS is displayed
13479 via a display vector, reset IT->current.dpvec_index to zero.
13480 (try_window_reusing_current_matrix): If a line ends in a display
13481 vector or the next line starts in a display vector, continue
13482 redrawing the window even though the character position of
13483 start_row was reached.
13486 2011-10-18 Chong Yidong <cyd@gnu.org>
13488 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13489 with nobreak-char-display too.
13491 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13493 Fix part 3 of bug#9771.
13494 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13495 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13496 non-neutral characters if the current character is a paragraph
13497 separator (a.k.a. Newline). This avoids running the same
13498 expensive loop twice, once when we consume the preceding newline
13499 and the other time when the line actually needs to be displayed.
13500 Avoid the loop when we see neutrals on the base embedding level
13501 following a character whose directionality is the same as the
13502 paragraph's. This avoids running the expensive loop when a line
13503 ends in a long sequence of neutrals, like control characters.
13504 Add assertion against STRONG_AL type. Slightly rearrange code
13505 that determines the type of a neutral given the first non-neutral
13507 (bidi_level_of_next_char): Set next_en_pos to zero when
13508 invalidating its info.
13510 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13512 * xdisp.c (push_display_prop): Determine whether to record string
13513 or buffer position by IT->string, not by IT->method. Allow
13514 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13515 (move_it_vertically_backward): Don't look for character position
13516 immediately after the newline when in a continuation line.
13519 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13521 * window.c (coordinates_in_window): Rewrite and delabelize
13522 vertical border check. (Bug#5357) (Bug#9618)
13524 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13526 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13527 errors in XSetWindowBorder (bug#9310).
13529 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13531 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13532 avoid crash when xmalloc overrun checking is enabled.
13534 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13536 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13537 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13538 cursor motion with <left> and <right> arrow keys.
13540 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13541 some callers set that themselves.
13543 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13545 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13546 display string and the previous row comes from the same string and
13547 is empty. (Bug#9739) (Bug#9738)
13549 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13551 * doc.c (get_doc_string): Encode file name (bug#9735).
13553 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13555 * bidi.c (bidi_level_of_next_char):
13556 * xdisp.c (get_visually_first_element): Remove old incorrect
13557 comments regarding the Unicode Line Separator character.
13559 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13561 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13563 * alloc.c (Fgc_status): Do not access beyond zombies array
13564 boundary if nzombies > MAX_ZOMBIES.
13565 * alloc.c (dump_zombies): Add missing format specifier.
13567 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13569 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13570 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13572 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13573 Some packages use them to denote characters with modifiers.
13575 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13577 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13578 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13579 matching a pp-number. Rename parameter var to var1.
13581 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13583 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13585 2011-10-08 Glenn Morris <rgm@gnu.org>
13587 * callint.c (Fcall_interactively): Give a more explicit error for the
13588 'c' case with a non-character input. (Bug#8479)
13590 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13592 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13594 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13595 lines that are hscrolled on the left.
13597 * dispnew.c (buffer_posn_from_coords): Account for a possible
13598 presence of header-line. (Bug#4426)
13600 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13602 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13603 Don't advertise functionality which we discourage or doesn't work.
13605 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13607 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13608 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13609 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13610 this makes Emacs dump core during garbage collection on rare
13611 occasions. sizeof is obviously inferior to offsetof here, so
13612 stick with offsetof.
13613 (GC_POINTER_ALIGNMENT): New macro.
13614 (mark_memory): Omit 3rd (offset) arg; caller changed.
13615 Don't assume EMACS_INT alignment is the same as pointer alignment.
13617 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13619 * keyboard.c (read_key_sequence_remapped): New var.
13620 (read_key_sequence): Compute remapping in the right buffer.
13621 (command_loop_1): Use read_key_sequence's remapping directly.
13623 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13625 * dired.c (file_name_completion): Don't expand file name.
13626 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13627 before checking file name handler.
13629 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13630 they've been requested explicitly (bug#9591).
13632 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13634 * keymap.c (Fsingle_key_description): Use make_specified_string
13635 instead of build_string to build string from push_key_description.
13638 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13640 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13641 This fixes a Y2038 bug on 64-bit hosts.
13642 * buffer.c (reset_buffer):
13643 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13644 (Fclear_buffer_auto_save_failure):
13645 Use 0, not -1, to represent an unset failure time, since time_t
13646 might not be signed.
13648 Remove dependency on glibc malloc internals.
13649 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13650 Move back here from lisp.h, but with their new implementations.
13651 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13652 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13653 * charset.c (charset_table_init): New static var.
13654 (syms_of_charset): Use it instead of xmalloc. This removes a
13655 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13656 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13657 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13658 Move back to alloc.c.
13659 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13660 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13662 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13664 * nsterm.m (windowDidResize): Call x_set_window_size only when
13665 ns_in_resize is true. Otherwise set pixelwidth/height and
13666 call change_frame_size (Bug#9628).
13668 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13670 Port --enable-checking=all to Fedora 14 x86-64.
13671 * charset.c (syms_of_charset): Also account for glibc malloc's
13672 internal overhead when calculating the initial malloc maximum.
13674 Port --enable-checking=all to Fedora 14 x86.
13675 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13677 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13678 (overrun_check_realloc, overrun_check_free):
13679 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13680 That way, xmalloc returns a properly-aligned pointer even if
13681 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13682 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13683 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13684 into account when calculating the initial malloc maximum.
13685 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13686 Move here from alloc.c, so that charset.c can use it too.
13687 Properly align; the old code wasn't right for common 32-bit hosts
13688 when configured with --enable-checking=all.
13689 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13690 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13692 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13694 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13697 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13699 * xdisp.c (compute_display_string_end): If there's no display
13700 string at CHARPOS, return -1.
13702 * bidi.c (bidi_fetch_char): When compute_display_string_end
13703 returns a negative value, treat the character as a normal
13704 character not covered by a display string. (Bug#9624)
13706 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13708 * lread.c (Fread_from_string): Fix typo in docstring.
13710 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13712 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13713 newline, reseat the iterator instead of bidi-iterating there one
13714 character at a time. (Bug#9610)
13715 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13716 TO_CHARPOS if the bidi iterator is at base embedding level.
13718 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13720 * lread.c (readevalloop): Use correct code for NBSP.
13721 (read1): Likewise. (Bug#9608)
13723 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13725 * dbusbind.c (Fdbus_register_signal): When service is not
13726 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13728 2011-09-25 Glenn Morris <rgm@gnu.org>
13730 * buffer.c (truncate-lines): Doc fix.
13732 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13734 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13735 (Fset_window_next_buffers): Doc fix.
13737 2011-09-24 Glenn Morris <rgm@gnu.org>
13739 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13741 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13743 Fix minor problems found by static checking.
13744 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13745 * indent.c (Fvertical_motion): Fix == vs = typo.
13747 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13749 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13750 Default value is now t. Doc fix.
13752 * indent.c (Fvertical_motion): Compute and apply the overshoot
13753 logic when moving up, not only when moving down. Fix the
13754 confusing name and values of the it_overshoot_expected variable;
13755 logic changes accordingly. (Bug#9254) (Bug#9549)
13757 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13758 CHARPOS is covered by a display string which includes newlines.
13759 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13760 is covered by a display string with embedded newlines.
13762 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13764 * dbusbind.c (Fdbus_register_signal): Add match rule to
13765 Vdbus_registered_objects_table. (Bug#9581)
13766 (Fdbus_register_method, Vdbus_registered_objects_table):
13769 2011-09-24 Jim Meyering <meyering@redhat.com>
13771 do not ignore write error for any output size
13772 The previous change was incomplete.
13773 While it makes emacs --batch detect the vast majority of stdout
13774 write failures, errors were still ignored whenever the output size is
13775 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13776 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13777 && echo FAIL: ignored write error
13778 FAIL: ignored write error
13779 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13780 && echo FAIL: ignored write error
13781 FAIL: ignored write error
13782 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13784 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13786 * emacs.c (Fkill_emacs): In noninteractive mode exit
13787 non-successfully if a write error occurred on stdout. (Bug#9574)
13789 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13791 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13794 * dispextern.h (struct it): Update the comment documenting what
13797 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13799 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13800 a display string, extend search for cursor position to end of row.
13801 (find_row_edges): If the row ends in a newline from a display
13802 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13803 Handle the case of a display string with multiple newlines.
13804 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13805 non-empty line. Fixes confusing cursor motion with arrow keys at
13806 the beginning of a line that starts with whitespace.
13808 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13810 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13813 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13815 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13816 boolean (Bug#9154).
13818 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13820 * xdisp.c (display_line): Record maximum and minimum buffer
13821 positions even if no glyphs were produced (e.g., by a zero-width
13822 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13823 buffer positions that will be removed from the glyph row because
13825 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13826 column is beyond frame width: don't subtract 1 "pixel" when
13827 computing width of the stretch.
13828 (reseat_at_next_visible_line_start): Undo the change made on
13829 2011-09-17 that saved paragraph information and restored it after
13830 the call to `reseat'. (Bug#9545)
13832 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13834 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13835 and turn window cursor on if cleared (Bug#9415).
13837 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13839 * search.c (boyer_moore): Take unibyte characters from pattern
13840 literally. (Bug#9458)
13842 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13844 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13846 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13848 Fix minor problem found by static checking.
13849 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13850 initialized, to pacify gcc -Wuninitialized.
13852 * fileio.c: Report proper errno when syscall falls.
13853 (Finsert_file_contents): Save and restore errno,
13854 so that report_file_error outputs the correct diagnostic.
13855 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13857 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13859 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13861 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13863 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13864 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13866 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13868 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13869 about the current paragraph and restore it after the call to reseat.
13871 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13872 (bidi_find_paragraph_start): Search back for paragraph beginning
13873 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13874 (bidi_move_to_visually_next): Only trigger paragraph-related
13875 computations when the last character is a newline or at EOB, not
13876 just any NEUTRAL_B. (Bug#9470)
13878 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13879 truncated lines if point is covered by a display string. (Bug#9524)
13881 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13883 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13884 (cons_to_x_long): New function.
13885 (lisp_data_to_selection_data): Use it. Correct the test for
13886 short-versus-long data; it was negated. Break out of vector
13887 loop, for efficiency, when a long datum is discovered.
13889 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13891 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13893 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13895 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13896 GCC PR/17406) by declaring this function with external scope.
13898 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13900 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13901 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13903 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13905 * editfns.c (Fformat): Correctly handle text properties on "%%".
13907 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13909 * xterm.c (x_draw_composite_glyph_string_foreground):
13910 * w32term.c (x_draw_composite_glyph_string_foreground):
13911 * term.c (encode_terminal_code):
13912 * composite.c (composition_update_it, get_composition_id):
13913 * xdisp.c (get_next_display_element)
13914 (fill_composite_glyph_string): Add comments about special meaning
13915 of TAB characters in a composition.
13917 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13919 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13920 This occurs when processing a multibyte format.
13921 Problem reported by Wolfgang Jenker.
13923 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13925 * xdisp.c (try_cursor_movement): Only check for exact match if
13926 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13928 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13930 Remove unused external symbols.
13931 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13932 * xdisp.c (calc_pixel_width_or_height): Now static.
13933 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13934 * indent.c (check_display_width):
13935 * w32term.c: Fix comment to match code.
13936 * xterm.c, xterm.h (x_catching_errors): Remove.
13938 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13940 * xselect.c: Use signed conversions more consistently (Bug#9498).
13941 (selection_data_to_lisp_data): Assume incoming selection data are
13942 signed integers, not unsigned. This is to be consistent with
13943 outgoing selection data, which was modified to use signed integers
13944 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13945 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13946 expects long, not unsigned long.
13948 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13950 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13951 computation of loop end. Reported by Johan Bockgård
13954 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13956 * frame.c (Fother_visible_frames_p): Function deleted.
13958 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13960 * indent.c (compute_motion): Process display vector front to back
13961 rather than the other way around. (Bug#2496)
13963 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13965 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13967 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13969 * minibuf.c (Fread_from_minibuffer): Doc fix.
13971 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13973 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13974 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13976 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13978 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13979 value for non-existent files.
13981 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13983 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13984 set its "size" to -1. This will set the modtime_size field of
13985 the corresponding buffer to -1, which is what
13986 verify-visited-file-modtime expects for files that do not exist.
13989 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13991 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13993 * lisp.h: ... from here. push_key_description is no longer
13994 defined in keyboard.c, so its declaration should not be in
13995 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13996 logically belongs with push_key_description.
13998 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14000 * buffer.h: Include <sys/types.h> instead of <time.h>.
14001 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14002 Problem reported by Herbert J. Skuhra.
14004 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14006 * xml.c (parse_region): Make the parsing work for
14007 non-comment-starting XML files again (bug#9144).
14009 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14011 * image.c (gif_load): Fix calculation of bottom and right corner.
14014 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14016 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14017 redisplay in small windows.
14019 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14021 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14023 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14025 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14026 Operate on live windows only.
14028 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14030 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14032 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14034 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14035 only under bidi iteration.
14037 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14039 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14041 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14043 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14044 Without this fix, the command to link temacs failed due to an
14045 undefined symbol __builtin_isnan. This is because
14046 /usr/include/iso/math_c99.h #defines isnan(x) to
14047 __builtin_isnan(x), but the bundled gcc, which identifies itself
14048 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14050 * floatfns.c (isnan): #undef, and then #define to a clone of
14052 (Fisnan): Always define, since it's always available now.
14053 (syms_of_floatfns): Always define isnan at the Lisp level.
14055 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14057 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14059 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14061 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14062 The previous code assumed that file offsets (off_t values) fit in
14063 EMACS_INT variables, which is not true on typical 32-bit hosts.
14064 The code messed up by falsely reporting buffer overflow in cases
14065 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14066 when "big" contains more than 2**29 bytes, even though this
14067 inserts just one byte and does not overflow the buffer.
14068 (Finsert_file_contents): Store file offsets as off_t
14069 values, not as EMACS_INT values. Check for overflow when
14070 converting between EMACS_INT and off_t. When checking for
14071 buffer overflow or for overlap, take the offsets into account.
14072 Don't use EMACS_INT for small values where int suffices.
14073 When checking for overlap, fix a typo: ZV was used where
14074 ZV_BYTE was intended.
14075 (Fwrite_region): Don't assume off_t fits into 'long'.
14076 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14078 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14080 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14082 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14084 sprintf-related integer and memory overflow issues (Bug#9412).
14086 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14087 (esprintf, exprintf, evxprintf): New functions.
14088 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14089 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14090 (modify_event_symbol): Do not assume that the length of
14091 name_alist_or_stem is safe to alloca and fits in int.
14092 (Fexecute_extended_command): Likewise for function name and binding.
14093 (Frecursion_depth): Wrap around reliably on integer overflow.
14094 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14095 since some callers pass EMACS_INT values.
14096 (Fsingle_key_description): Don't crash if symbol name contains more
14097 than MAX_ALLOCA bytes.
14098 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14099 (get_minibuffer): Arg is now EMACS_INT, not int.
14100 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14101 (esprintf, exprintf, evxprintf): New decls.
14102 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14104 * dbusbind.c (signature_cat): New function.
14105 (xd_signature, Fdbus_register_signal):
14106 Do not overrun buffer; instead, report string overflow.
14108 * dispnew.c (add_window_display_history): Don't overrun buffer.
14109 Truncate instead; this is OK since it's just a log.
14111 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14112 even if the time zone offset is outlandishly large.
14113 Don't mishandle offset == INT_MIN.
14115 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14116 when creating daemon; the previous buffer-overflow check was incorrect.
14118 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14119 which has the guts of the old verror function.
14121 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14122 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14124 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14125 (font_unparse_xlfd): Don't blindly alloca long strings.
14126 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14127 fits in int, when using sprintf. Use single snprintf to count
14128 length of string rather than counting it via multiple sprintfs;
14129 that's simpler and more reliable.
14130 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14131 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14132 sprintf, in case result does not fit in int.
14134 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14135 (fontset_from_font): Print it.
14137 * frame.c (tty_frame_count): Now printmax_t, not int.
14138 (make_terminal_frame, set_term_frame_name): Print it.
14139 (x_report_frame_params): In X, window IDs are unsigned long,
14140 not signed long, so print them as unsigned.
14141 (validate_x_resource_name): Check for implausibly long names,
14142 and don't assume name length fits in 'int'.
14143 (x_get_resource_string): Don't blindly alloca invocation name;
14144 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14147 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14148 (xg_check_special_colors, xg_set_geometry):
14149 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14151 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14152 Use esprintf, not sprintf, in case result does not fit in int.
14154 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14155 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14156 it as a large positive number.
14157 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14158 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14160 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14161 in case result does not fit in int.
14163 * print.c (float_to_string): Detect width overflow more reliably.
14164 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14165 buffer overrun. Don't assume list length fits in 'int'. Treat
14166 print length of 0 as 0, not as infinity; to be consistent with other
14167 uses of print length in this function. Don't overflow print length
14168 index. Don't assume hash table size fits in 'long', or that
14169 vectorlike size fits in 'unsigned long'.
14171 * process.c (make_process): Use printmax_t, not int, to format
14172 process-name gensyms.
14174 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14176 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14177 to avoid potential buffer overrun.
14179 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14180 if X resource line is longer than 512 bytes.
14182 * xfns.c (x_window): Make sprintf buffer a bit bigger
14183 to avoid potential buffer overrun.
14185 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14187 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14189 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14191 Integer overflow fixes for scrolling, etc.
14192 Without these, Emacs silently mishandles large integers sometimes.
14193 For example, "C-u 4294967297 M-x recenter" was treated as if
14194 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14196 * xdisp.c (try_window_id): Check Emacs fixnum range before
14197 converting to 'int'.
14199 * window.c (window_scroll_line_based, Frecenter):
14200 Check that an Emacs fixnum is in range before assigning it to 'int'.
14201 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14202 values converted from Emacs fixnums.
14203 (Frecenter): Don't wrap around a line count if it is out of 'int'
14204 range; instead, treat it as an extreme value.
14205 (Fset_window_configuration, compare_window_configurations):
14206 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14208 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14209 that can exceed INT_MAX. Check that EMACS_INT value is in range
14210 before assigning it to the (possibly-narrower) index.
14211 (match_limit): Don't assume that a fixnum can fit in 'int'.
14213 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14216 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14217 (Fvertical_motion): Don't wrap around LINES values that don't fit
14218 in 'int'. Instead, treat them as extreme values. This is good
14219 enough for windows, which can't have more than INT_MAX lines anyway.
14221 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14223 * Require libxml/parser.h to avoid compilation warning.
14225 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14227 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14228 since this reportedly can destroy thread storage.
14230 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14232 * syntax.c (find_defun_start): Update all cache variables if
14233 exiting early (Bug#9401).
14235 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14237 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14239 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14240 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14241 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14243 * term.c (tty_append_glyph): New function.
14244 (produce_stretch_glyph): Static function and its prototype deleted.
14246 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14249 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14251 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14252 when checking :margin (Bug#9390).
14253 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14254 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14255 so that the name doesn't mislead. All uses changed.
14257 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14259 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14262 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14264 * xdisp.c (move_it_to): Don't bail out early when reaching
14265 position beyond to_charpos, if we are scanning backwards.
14266 (move_it_vertically_backward): When DY == 0, make sure we get to
14267 the first character in the line after the newline.
14269 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14271 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14272 (ccl_driver): Do not generate an out-of-range pointer.
14273 (Fccl_execute_on_string): Remove unnecessary check for
14274 integer overflow, noted by Stefan Monnier in
14275 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14276 Remove a FIXME that didn't need fixing.
14277 Simplify the newly-introduced buffer reallocation code.
14279 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14281 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14283 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14285 Integer and memory overflow issues (Bug#9196).
14287 * doc.c (get_doc_string): Rework so that
14288 get_doc_string_buffer_size is the actual buffer size, rather than
14289 being 1 less than the actual buffer size; this makes xpalloc more
14292 * image.c (x_allocate_bitmap_record, cache_image):
14293 * xselect.c (Fx_register_dnd_atom):
14294 Simplify previous changes by using xpalloc.
14296 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14297 since either will do and ptrdiff_t is convenient with xpalloc.
14299 * charset.c (charset_table_size)
14300 (struct charset_sort_data.priority): Now ptrdiff_t.
14301 (charset_compare): Don't overflow if priorities differ greatly.
14302 (Fsort_charsets): Don't assume list length fits in int.
14303 Check for size-calculation overflow when allocating sort data.
14304 (syms_of_charset): Allocate an initial charset table that is
14305 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14307 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14309 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14310 The actual value is always <= INT_MAX, and leaving it unsigned made

14313 * dispextern.h (struct glyph_matrix.rows_allocated)
14314 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14315 with xpalloc. The values are still always <= INT_MAX.

14325 (revalidate_region_cache, know_region_cache, region_cache_forward)
14326 (region_cache_backward, pp_cache):
14327 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14328 so that ptrdiff_t * can be passed to xpalloc.
14329 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14330 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

14345 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14347 Don't update size of array until after memory allocation succeeds,
14348 because xmalloc/xrealloc may not return.
14349 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14350 now that we have proper integer overflow checking.
14351 (record_overlay_string, overlay_strings): Catch overflows when
14352 calculating size of overlay_str_buf.
14354 * callproc.c (Fcall_process): Check for size overflow when
14355 calculating size of args2.
14356 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14357 Normally we prefer signed values, but sticking with ptrdiff_t would
14358 require adding more-complicated checks.
14360 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14361 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14362 Redo buffer-overflow calculations to avoid integer overflow.
14363 Add a FIXME comment where memory seems to be over-allocated.
14365 * character.c (Fstring): Check for size-calculation overflow.
14367 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid

14401 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14403 * emacs.c (main): Do not reallocate argv, since there is a null at
14404 the end that can be overwritten, and this way there's no need to
14405 worry about size-calculation overflow.
14406 (sort_args): Check for size-calculation overflow.
14408 * eval.c (init_eval_once, grow_specpdl): Don't update size until

14414 Check for integer overflow.
14415 (x_set_alpha): Do not assume XINT fits in int.
14417 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14418 This is for the members text_lines, text_cols, total_lines, total_cols,
14419 where the system imposes an 'int' limit.
14421 * fringe.c (Fdefine_fringe_bitmap):
14422 Don't update size until alloc works.

14427 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14428 Check for size-calculation overflow.
14429 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14430 do, as we prefer signed integers.

14437 * gtkutil.h: Change prototypes to match the above.
14439 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

14486 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14487 for command line length. Do not attempt to address one before the
14488 beginning of an array, as that's not portable.

14535 (X_LONG_MIN): New macros.
14536 Use them to make the following changes clearer.
14537 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14538 This change doesn't affect the value now, but it may help remind
14539 future maintainers not to raise the value too much later.
14540 (SELECTION_QUANTUM): Remove, replacing with ...
14541 (selection_quantum): ... new function, which avoids overflow.
14543 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14544 assumption that selection length fits in 'int'.

14561 Don't store size until memory allocation succeeds.
14562 (x_get_window_property): Plug memory leak on memory exhaustion.
14563 Don't double-block input; malloc is safe here. Don't assume 2**34
14564 - 4 fits in unsigned long. Add an xassert to check
14565 XGetWindowProperty overflow. Be more careful about overflow
14566 calculations, and distinguish size from memory overflow better.
14567 (receive_incremental_selection): When tracing, don't assume
14568 unsigned int is less than INT_MAX.
14569 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

14572 in the range -65535 through -1 fit in an X unsigned short.
14573 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14574 result parameters unless successful. Rely on cons_to_unsigned
14575 to report problems with elements; the old code wasn't right anyway.
14576 (x_check_property_data): Check for int overflow; we cannot use
14577 a wider type due to X limits.

14610 * lisp.h (hash_lookup, hash_put):
14611 * minibuf.c (Ftest_completion):
14612 Use ptrdiff_t for hash table indexes, not int (which is too
14613 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

14625 with outlandish widths.
14626 * character.h (sanitize_tab_width): Rename from sanitize_width,

14652 (make_lispy_movement): Use same integer type in forward decl
14653 that is used in the definition.

14655 Change bufsize argument back to int, undoing my 2011-03-30 change.
14656 We prefer signed types, and int is wide enough here.
14657 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14658 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14659 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14660 length, not size_t. Use ptrdiff_t for index, not int.
14661 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14662 possibility of integer overflow.

14690 Prefer int to unsigned where either will do.
14691 (tiff_handler): New function, combining the cores of the
14692 old tiff_error_handler and tiff_warning_handler.
14693 This function is rewritten to use vsnprintf and thereby avoid
14694 stack buffer overflows. It uses only the features of vsnprintf
14695 that are common to both POSIX and native Microsoft.
14696 (tiff_error_handler, tiff_warning_handler): Use it.
14697 (tiff_load, gif_load, imagemagick_load_image):
14698 Don't assume :index value fits in 'int'.

14701 the integer types that MagickCropImage accepts. Don't assume
14702 Vimagemagick_render_type has a nonnegative value. Don't assume

14740 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
14741 buffers, return left-to-right.
14742 (set_cursor_from_row): Consider candidate row a win if its glyph
14743 represents a newline and point is on that newline. Fixes cursor
14744 positioning on the newline at EOL of R2L text within L2R
14745 paragraph, and vice versa.
14746 (try_cursor_movement): Check continued rows, in addition to
14747 continuation rows. Fixes unwarranted scroll when point enters a
14748 continued line of R2L text within an L2R paragraph, or vice versa.
14749 (cursor_row_p): Consider the case of point being equal to
14750 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

14774 2011-08-23 Eli Zaretskii <eliz@gnu.org>
14776 * xdisp.c (redisplay_window): When computing centering_position,
14777 account for the height of the header line. (Bug#8874)
14779 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14780 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14781 candidate is selected by the mouse, and that candidate has a
14782 composed character under the mouse.
14784 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14785 coordinates reported by pos-visible-in-window-p for a composed
14786 character in column zero.
14788 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

14792 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14794 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14795 consider it a hit if to_charpos is anywhere in the range of the
14796 composed buffer positions.
14798 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14800 * image.c (gif_load): Don't assume that each subimage has the same
14801 dimensions as the base image. Handle disposal method that is
14802 "undefined" by the gif spec (Bug#9335).
14804 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14806 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
14807 (Fcondition_case): Document `debug' symbol in error handler.
14809 2011-08-19 Eli Zaretskii <eliz@gnu.org>
14811 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14812 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14813 from an Org mode buffer to a Speedbar frame.
14815 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14816 a composition, take its buffer position from IT->cmp_it.charpos.
14817 Fixes cursor positioning at the beginning of a line that begins
14818 with a composed character.
14820 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14822 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14823 character bidirectional type, use STRONG_L instead. Fixes crashes
14824 in a buffer produced by `describe-categories'.
14826 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14827 members before the level stack, so they would be saved and
14828 restored when copying iterator state. Fixes incorrect reordering
14829 around TABs covered by display properties.
14831 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14833 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
14835 2011-08-17 Chong Yidong <cyd@stupidchicken.com>

14838 (internal_condition_case_2, internal_condition_case_n):
14839 Remove unnecessary aborts (Bug#9081).
14841 2011-08-17 Eli Zaretskii <eliz@gnu.org>
14843 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
14844 has no `load' handler, try opening the file locally. (Bug#9311)
14846 2011-08-16 Ken Brown <kbrown@cornell.edu>
14848 * gmalloc.c: Expand comment.
14850 2011-08-16 Eli Zaretskii <eliz@gnu.org>

14899 after the pid of the process is set to -1 (Bug#8162).
14901 2011-08-14 Eli Zaretskii <eliz@gnu.org>
14903 * xdisp.c (move_it_in_display_line_to): Don't invoke
14904 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14905 ppos_it. Fixes vertical cursor motion when line beginning is
14906 covered by an image. (Bug#9296)
14908 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14910 * nsterm.h (ns_run_ascript): Declare.

14915 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14916 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14917 the event loop. Get status from as_status (Bug#7276).
14919 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14920 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14921 the event loop (Bug#7276).
14923 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14925 * gnutls.c (QCgnutls_bootprop_priority)

14947 (Fnetwork_interface_list): Allocate in increments of bytes instead
14948 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14949 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14951 (struct ifflag_def): notrailers is smart on OSX.
14952 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14953 Get hardware address with getifaddrs if available.
14955 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14957 * xdisp.c (iterate_out_of_display_property): xassert that
14958 IT->position is set to within IT->object's boundaries. Break from
14959 the loop as soon as EOB is reached; avoids infloops in redisplay
14960 when IT->position is set up wrongly due to some bug.
14961 Set IT->current to match the bidi iterator unconditionally.
14962 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14963 entry. Force push_it to save on the stack the current
14964 buffer/string position, to be restored by pop_it. Fix flags in
14965 the iterator structure wrt the object coming from a display
14966 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14967 properties. (Bug#9284)
14969 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14971 * fontset.c (fontset_get_font_group): Add proper type checks.

15003 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15004 to show the arg `TIME' instead of `TIMEVAL'.
15006 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15008 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15009 display property strides EOL and includes a newline, as in
15010 longlines-mode. (Bug#9254)
15011 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15012 word-wrap under bidirectional display. (Bug#9224)
15014 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15015 is non-zero, even if the data buffer is NULL. Fixes a crash in
15016 vertical-motion with longlines-mode. (Bug#9254)
15018 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15020 * bidi.c <bidi_cache_total_alloc>: Now static.

15026 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15027 amount allocated this far in `bidi_cache_total_alloc'.
15028 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15029 non-zero, only free the data buffer without restoring the cache
15030 contents. All callers changed.
15032 * dispextern.h (bidi_unshelve_cache): Update prototype.
15034 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15035 (move_it_in_display_line, move_it_to)
15036 (move_it_vertically_backward, move_it_by_lines): Replace the call
15037 to xfree to an equivalent call to bidi_unshelve_cache.
15038 (move_it_in_display_line_to): Fix logic of returning
15039 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)

15095 DISP_PROP_P, and pass it to compute_display_string_pos.
15096 Only handle text covered by a display string if DISP_PROP_P is returned
15097 non-zero. All callers of bidi_fetch_char changed.
15099 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

15185 'malloc' might be invoked reentrantly.
15187 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15188 In other words, assume that every image size is allowed, on non-X
15189 hosts. This assumption is probably wrong, but it lets Emacs compile.

15201 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15203 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15205 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15207 Integer signedness and overflow and related fixes. (Bug#9079)
15209 * bidi.c: Integer size and overflow fixes.
15210 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15211 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15212 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15213 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15214 (bidi_find_other_level_edge):
15215 Use ptrdiff_t instead of EMACS_INT where either will do.
15216 This works better on 32-bit hosts configured --with-wide-int.
15217 (bidi_cache_ensure_space): Check for size-calculation overflow.
15218 Use % rather than repeated addition, for better worst-case speed.
15219 Don't set bidi_cache_size until after xrealloc returns, because it
15221 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15222 (bidi_cache_ensure_space): Also check that the bidi cache size
15223 does not exceed that of the largest Lisp string or buffer. See Eli
15224 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15226 * alloc.c (__malloc_size_t): Remove.
15227 All uses replaced by size_t. See Andreas Schwab's note
15228 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15230 * image.c: Improve checking for integer overflow.
15231 (check_image_size): Assume that f is nonnull, since
15232 it is always nonnull in practice. This is one less thing to
15233 worry about when checking for integer overflow later.
15234 (x_check_image_size): New function, which checks for integer
15235 overflow issues inside X.
15236 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15237 This removes the need for a memory_full check.
15238 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15239 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15240 (xbm_read_bitmap_data): Change locals back to 'int', since
15241 their values must fit in 'int'.
15242 (xpm_load_image, png_load, tiff_load):
15243 Invoke x_create_x_image_and_pixmap earlier,
15244 to avoid much needless work if the image is too large.
15245 (tiff_load): Treat overly large images as if
15246 x_create_x_image_and_pixmap failed, not as malloc failures.
15247 (gs_load): Use x_check_image_size.
15249 * gtkutil.c: Omit integer casts.
15250 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15251 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15253 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15255 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15256 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15257 would wrongly return t on a 64-bit host.
15259 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15260 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15261 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15262 and therefore cause GCC to emit a bogus diagnostic in some cases.
15264 * image.c: Integer signedness and overflow and related fixes.
15265 This is not an exhaustive set of fixes, but it's time to
15266 record what I've got.
15267 (lookup_pixel_color, check_image_size): Remove redundant decls.
15268 (check_image_size): Don't assume that arbitrary EMACS_INT values
15269 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15270 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15271 (tiff_load, imagemagick_load_image):
15272 Check for overflow in size calculations.
15273 (x_create_x_image_and_pixmap): Remove unnecessary test for
15274 xmalloc returning NULL; that can't happen.
15275 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15276 (xpm_color_bucket): Use better integer hashing function.
15277 (xpm_cache_color): Don't possibly over-allocate memory.
15278 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15279 (gif_memory_source):
15280 Use ptrdiff_t, not int or size_t, to record sizes.
15281 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15282 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15283 either works, as we prefer signed integers.
15284 (tiff_read_from_memory, tiff_write_from_memory):
15285 Return tsize_t, not size_t, since that's what the TIFF API wants.
15286 (tiff_read_from_memory): Don't fail simply because the read would
15287 go past EOF; instead, return a short read.
15288 (tiff_load): Omit no-longer-needed casts.
15289 (Fimagemagick_types): Don't assume size fits into 'int'.
15291 Improve hashing quality when configured --with-wide-int.
15292 * fns.c (hash_string): New function, taken from sxhash_string.
15293 Do not discard information about ASCII character case; this
15294 discarding is no longer needed.
15295 (sxhash-string): Use it. Change sig to match it. Caller changed.
15296 * lisp.h: Declare it.
15297 * lread.c (hash_string): Remove, since we now use fns.c's version.
15298 The fns.c version returns a wider integer if --with-wide-int is
15299 specified, so this should help the quality of the hashing a bit.
15301 * emacs.c: Integer overflow minor fix.
15302 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15303 Define only if GNU_LINUX.
15304 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15306 * dispnew.c: Integer signedness and overflow fixes.
15307 Remove unnecessary forward decls, that were a maintenance hassle.
15308 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15310 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15311 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15312 (prepare_desired_row, line_draw_cost):
15313 Use int, not unsigned, where either works.
15314 (save_current_matrix, restore_current_matrix):
15315 Use ptrdiff_t, not size_t, where either works.
15316 (init_display): Check for overflow more accurately, and without
15317 relying on undefined behavior.
15319 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15320 Remove, replacing with the new symbols in lisp.h. All uses changed.
15321 * fileio.c (make_temp_name):
15322 * filelock.c (lock_file_1, lock_file):
15323 * xdisp.c (message_dolog):
15324 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15325 Use pMd etc. instead.
15326 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15327 replacing the pWIDE etc. symbols removed from editfns.c.
15329 * keyboard.h (num_input_events): Now uintmax_t.
15330 This is (very slightly) less likely to mess up due to wraparound.
15333 * buffer.c: Integer signedness fixes.
15334 (alloc_buffer_text, enlarge_buffer_text):
15335 Use ptrdiff_t rather than size_t when either will do, as we prefer
15338 * alloc.c: Integer signedness and overflow fixes.
15339 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15340 (__malloc_size_t): Default to size_t, not to int.
15341 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15342 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15343 Prefer ptrdiff_t to size_t when either would do, as we prefer
15345 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15346 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15347 Now const. Initialize with values that are in range even if char
15349 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15350 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15351 These functions do the right thing with sizes > 2**32.
15352 (check_depth): Now ptrdiff_t, not int.
15353 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15354 Adjust to new way of storing sizes. Check for size overflow bugs
15356 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15357 slightly wrong anyway, as it missed one instance of
15358 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15359 (refill_memory_reserve): Omit needless cast to size_t.
15360 (mark_object_loop_halt): Mark as externally visible.
15362 * xselect.c: Integer signedness and overflow fixes.
15363 (Fx_register_dnd_atom, x_handle_dnd_message):
15364 Use ptrdiff_t, not size_t, since we prefer signed.
15365 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15366 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15367 x_dnd_atoms_size and x_dnd_atoms_length.
15369 * doprnt.c: Prefer signed to unsigned when either works.
15371 * doprnt.c (doprnt):
15373 * xdisp.c (vmessage):
15374 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15375 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15376 prefer signed arithmetic to avoid comparison confusion.
15377 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15378 but is a bit tricky.
15380 Assume freestanding C89 headers, string.h, stdlib.h.
15381 * data.c, doprnt.c, floatfns.c, print.c:
15382 Include float.h unconditionally.
15383 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15384 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15385 * regex.c: Likewise for stddef.h, string.h.
15386 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15387 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15388 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15389 (STDC_HEADERS): Remove obsolete defines.
15390 * sysdep.c: Include limits.h unconditionally.
15392 Assume support for memcmp, memcpy, memmove, memset.
15393 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15394 * regex.c (memcmp, memcpy):
15395 Remove; we assume C89 now.
15397 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15398 (__malloc_safe_bcopy): Remove; no longer needed.
15400 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15401 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15402 well either way, and we prefer signed to unsigned.
15404 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15406 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15407 closes the connection while we're reading (bug#9182).
15409 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15411 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15412 are specified (Bug#9168).
15414 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15416 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15417 Found by GCC static checking and --with-wide-int on a 32-bit host.
15419 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15421 * xdisp.c (compute_display_string_pos): Fix logic of caching
15422 previous display string position. Initialize cached_prev_pos to
15423 -1. Fixes slow-down at the beginning of a buffer.
15425 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15427 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15428 for attrs[LFACE_FONTSET_INDEX].
15430 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15432 * xml.c (parse_region): Remove unused local
15433 that was recently introduced.
15435 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15437 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15438 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15440 * xdisp.c (move_it_in_display_line_to): Record the best matching
15441 position for TO_CHARPOS while scanning the line, and restore it on
15442 exit if none of the characters scanned was an exact match.
15443 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15444 when exact match is impossible due to invisible text, and the
15445 lines are truncated.
15447 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15449 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15452 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15454 Fix a significant slow-down of cursor motion with C-n, C-p,
15455 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15456 auto-repeat under bidi redisplay in fontified buffers.
15457 * xdisp.c (compute_stop_pos_backwards): New function.
15458 (next_element_from_buffer): Call compute_stop_pos_backwards to
15459 find a suitable prev_stop when we find ourselves before
15461 (reseat): Don't look for prev_stop, as that could mean a very long
15463 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15464 <cached_disp_overlay_modiff>: Cache for last found display string
15466 (compute_display_string_pos): Return the cached position if asked
15467 about the same buffer in the same area of character positions, and
15468 the buffer wasn't changed since the time the display string
15469 position was cached.
15471 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15473 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15474 is an integer, which is important for empty lines. (Bug#9149)
15476 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15478 * frame.c (Fmodify_frame_parameters): In tty case, update the
15479 default face if necessary (Bug#4238).
15481 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15483 * editfns.c (Fstring_to_char): No need to explain what a character
15484 is in the docstring (Bug#6576).
15486 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15488 * xml.c (parse_region): Make sure we always return a tree.
15490 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15492 * xml.c (parse_region): If a document contains only comments,
15495 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15497 * xml.c (make_dom): Return comments, too.
15499 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15502 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15503 and the surrounding thread.
15504 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15505 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15506 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15508 * s/openbsd.h (BROKEN_SIGIO): Define.
15509 * unexelf.c (unexec) [__OpenBSD__]:
15510 Don't update the .mdebug section of the Alpha COFF symbol table.
15512 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15514 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15517 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15519 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15520 This fixes some race conditions on the permissions of any newly
15523 * alloc.c (valid_pointer_p): Use pipe, not open.
15524 This fixes some permissions issues when debugging.
15526 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15527 If fchown fails to set both uid and gid, try to set just gid,
15528 as that is sometimes allowed. Adjust the file's mode to eliminate
15529 setuid or setgid bits that are inappropriate if fchown fails.
15531 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15533 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15534 to compare Lisp_Objects.
15535 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15536 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15537 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15539 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15541 * lread.c (read_integer): Unread even EOF character.
15542 (read1): Likewise. Properly record start position of symbol.
15544 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15545 symbol character follows.
15547 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15549 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15550 This works around a problem with the previous change to Fcopy_file.
15551 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15552 and without this change, GCC might complain about discarding
15553 fchown's return value.
15555 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15557 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15559 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15561 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15563 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15565 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15566 it's used from the C level.
15568 * process.c: Use the same condition for POLL_FOR_INPUT in both
15569 keyboard.c and process.c (bug#1858).
15571 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15573 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15574 (Fgnutls_boot): Use it.
15576 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15578 * doc.c (Fsubstitute_command_keys): Revert last change.
15580 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15582 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15583 quotes the next character, and doesn't affect other longer
15584 sequences (bug#8935).
15586 * lread.c (syms_of_lread): Clarify that is isn't only
15587 `eval-buffer' and `eval-defun' that's affected by
15588 `lexical-binding' (bug#8460).
15590 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15592 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15593 bidi redisplay when a line includes both an image and is truncated.
15595 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15597 Fix minor problems found by static checking.
15598 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15599 (elsz): Now a signed constant, not a size_t var. We prefer signed
15600 types to unsigned, to avoid integer comparison confusion. Without
15601 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15602 "cannot optimize loop, the loop counter may overflow", a symptom
15604 * indent.c (Fvertical_motion): Mark locals as initialized.
15605 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15607 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15609 * search.c (Fre_search_backward): Mention `case-fold-search' in
15610 all the re_search_* functions (bug#8138).
15612 * keyboard.c (Fopen_dribble_file): Document when the file is
15615 2011-07-14 Eli Zaretskii <eliz@gnu.org>
15617 * bidi.c (bidi_dump_cached_states): Fix format of displaying
15620 Support bidi reordering of display and overlay strings.
15621 * xdisp.c (compute_display_string_pos)
15622 (compute_display_string_end): Accept additional argument STRING.
15623 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15624 (reseat_to_string): Initialize bidi_it->string.s and
15625 bidi_it->string.schars.
15626 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15627 NULL (avoids a crash in bidi_paragraph_init).
15628 Initialize itb.string.lstring.
15629 (init_iterator): Call bidi_init_it only of a valid
15630 buffer position was specified. Initialize paragraph_embedding to
15632 (reseat_to_string): Initialize the bidi iterator.
15633 (display_string): If we need to ignore text properties of
15634 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15635 original value of -1 will not work with bidi.)
15636 (compute_display_string_pos): First arg is now struct
15637 `text_pos *'; all callers changed. Support display properties on
15639 (compute_display_string_end): Support display properties on Lisp
15641 (init_iterator, reseat_1, reseat_to_string): Initialize the

16129 (clone_per_buffer_values): Don't assume that

16131 This isn't true in general, and it's particularly not true
16132 if Emacs is configured with --with-wide-int.
16133 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16134 New macros, used in the buffer.c change.

16170 Random fixes. E.g., (random) never returned negative values.
16171 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16172 subseconds part to the entropy, as that's a bit more random.
16173 Prefer signed to unsigned, since the signedness doesn't matter and
16174 in general we prefer signed. When given a limit, use a
16175 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16176 latter isn't right if USE_2_TAGS_FOR_INTS.
16177 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16178 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16182 * textprop.c (text_property_stickiness):
16183 Obey Vtext_property_default_nonsticky.

16190 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16191 This is more efficient than Ffile_directory_p and avoids a minor race.
16193 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16195 * buffer.c (Foverlay_put): Say what the return value is
16198 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16199 is a directory before asking whether to use the file name
16201 (barf_or_query_if_file_exists): Make the "File is a directory"
16202 error be more correct.
16204 * fns.c (Frequire): Remove the mention of the .gz files, since
16205 that's installation-specific, but keep the mention of
16206 `get-load-suffixes'.

16210 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

16218 Qgnutls_bootprop_verify_error (which is no longer used).
16220 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16221 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16222 Also (re)move comments that are misplaced or no longer relevant.
16224 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16226 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16285 (syms_of_keymap): Defsubr make-composed-keymap.
16286 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16323 * eval.c (struct backtrace): Simplify and port the data structure.
16324 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16325 signed bit field, as this assumption is not portable and it makes
16326 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16327 "char debug_on_exit : 1" as this is not portable either; instead,
16328 use the portable "unsigned int debug_on_exit : 1". Remove unused
16329 member evalargs. Remove obsolete comments about cc bombing out.
16331 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16517 to improve quality of diagnostics for out-of-range radices.
16518 Calculate buffer size correctly for out-of-range radices.
16519 (read1): Check for integer overflow in radices, and in
16520 read-circle numbers.
16521 (read_escape): Avoid int overflow.
16522 (Fload, openp, read_buffer_size, read1)
16523 (substitute_object_recurse, read_vector, read_list, map_obarray):
16524 Use ptrdiff_t, not int, for sizes.
16525 (read1): Use EMACS_INT, not int, for sizes.
16526 Check for size overflow.
16528 * image.c (cache_image): Check for size arithmetic overflow.
16530 * lread.c: Integer overflow issues.
16531 (saved_doc_string_size, saved_doc_string_length)
16532 (prev_saved_doc_string_size, prev_saved_doc_string_length):
16533 Now ptrdiff_t, not int.
16534 (read1): Don't assume doc string length fits in int. Check for
16535 out-of-range doc string lengths.
16536 (read_list): Don't assume file position fits in int.
16537 (read_escape): Check for hex character overflow.
16539 2011-06-22 Leo Liu <sdl.web@gmail.com>
16541 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16542 Move to minibuffer.el.
16544 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16546 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16547 The following patches are for when GLYPH_DEBUG && !XASSERT.
16548 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16549 * dispnew.c (flush_stdout):
16550 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16551 Mark as externally visible.
16552 * dispnew.c (check_window_matrix_pointers): Now static.
16553 * dispnew.c (window_to_frame_vpos):
16554 * xfns.c (unwind_create_frame):
16555 * xterm.c (x_check_font): Remove unused local.
16556 * scroll.c (CHECK_BOUNDS):
16557 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16558 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16559 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16560 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16561 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16563 (debug_method_add): Use va_list and vsprintf rather than relying
16564 on undefined behavior with wrong number of arguments.
16565 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16566 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16567 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16568 since we're not interested in debugging glyphs with old libraries.
16569 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16570 GCC 4.6.0's static checking.
16572 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16574 Integer overflow and signedness fixes (Bug#8873).

16583 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16584 (x_create_bitmap_from_xpm_data):
16585 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16586 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16588 * xfaces.c (load_pixmap):
16589 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16590 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16591 (.bitmaps_last, struct x_output.icon_bitmap):
16592 Use ptrdiff_t, not int, for bitmap indexes.
16593 (x_allocate_bitmap_record): Check for size overflow.
16594 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16596 Use ptrdiff_t, not int, for overlay counts.
16597 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16598 * editfns.c (overlays_around, get_pos_property):
16599 * textprop.c (get_char_property_and_overlay):
16600 * xdisp.c (next_overlay_change, note_mouse_highlight):
16601 * xfaces.c (face_at_buffer_position):
16602 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16603 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16604 (Fnext_overlay_change, Fprevious_overlay_change)
16605 (mouse_face_overlay_overlaps, Foverlays_in):
16606 Use ptrdiff_t, not int, for sizes.
16607 (overlays_at, overlays_in): Check for size-calculation overflow.
16609 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16611 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16612 (x_session_initialize): Do not assume string length fits in int.
16614 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16615 This is unlikely, but can occur if DPI is outlandish.
16617 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16618 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16620 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16621 * xrdb.c (magic_file_p, search_magic_path):
16622 Omit last arg SUFFIX; it was always 0. All callers changed.
16623 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16625 * xfont.c (xfont_match): Avoid need for strlen.
16627 * xfns.c: Don't assume strlen fits in int.
16628 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16630 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16631 not unsigned long, as we prefer signed integers. All callers changed.
16632 Detect integer overflow in repeat count.
16633 (message_dolog): Don't assume print length fits in 39 bytes.
16634 (display_mode_element): Don't assume strlen fits in int.
16636 * termcap.c: Don't assume sizes fit in int and never overflow.
16637 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16638 (gobble_line): Check for size-calculation overflow.
16640 * minibuf.c (Fread_buffer):
16641 * lread.c (intern, intern_c_string):
16642 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16643 Don't assume string length fits in int.
16645 * keyboard.c (parse_tool_bar_item):
16646 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16648 * font.c: Don't assume string length fits in int.
16649 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16650 Use ptrdiff_t, not int.
16651 (font_intern_prop): Don't assume string length fits in int.
16652 Don't assume integer property fits in fixnum.
16653 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16655 * filelock.c: Fix some buffer overrun and integer overflow issues.
16656 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16657 Reformulate so as not to need the command string.
16658 Invoke gzip -cd rather than gunzip, as it's more portable.
16659 (lock_info_type, lock_file_1, lock_file):
16660 Don't assume pid_t and time_t fit in unsigned long.
16661 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16662 (current_lock_owner): Prefer signed type for sizes.
16663 Use memcpy, not strncpy, where memcpy is what is really wanted.
16664 Don't assume (via atoi) that time_t and pid_t fit in int.
16665 Check for time_t and/or pid_t out of range, e.g., via a network share.
16666 Don't alloca where an auto var works fine.
16668 * fileio.c: Fix some integer overflow issues.
16669 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16670 Don't assume string length fits in int.
16671 (directory_file_name): Don't assume string length fits in long.
16672 (make_temp_name): Don't assume pid fits in int, or that its print
16673 length is less than 20.
16675 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16677 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16679 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16681 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16682 We prefer signed integers, even for size calculations.
16684 * emacs.c: Don't assume string length fits in 'int'.
16685 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16686 (main): Don't invoke strlen when not needed.
16688 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16689 (XD_DEBUG_MESSAGE): Don't waste a byte.
16691 * callproc.c (getenv_internal_1, getenv_internal)
16692 (Fgetenv_internal):
16693 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16695 * lread.c (invalid_syntax): Omit length argument.
16696 All uses changed. This doesn't fix a bug, but it simplifies the
16697 code away from its former Hollerith-constant appearance, and it's
16698 one less 'int' to worry about when looking at integer-overflow issues.
16699 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16701 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16702 This didn't break anything, but it didn't help either.
16703 It's confusing to put a bogus integer in a place where the actual
16704 value does not matter.
16705 (LIST_END_P): Remove unused macro and its bogus comment.
16706 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16708 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16709 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16711 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16712 We prefer signed types, and the value cannot exceed the EMACS_INT
16713 range anyway (because otherwise the length would not be representable).
16714 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16715 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16716 This avoids a GCC warning when WIDE_EMACS_INT.
16718 * indent.c (sane_tab_width): New function.
16719 (current_column, scan_for_column, Findent_to, position_indentation)
16720 (compute_motion): Use it. This is just for clarity.
16721 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16723 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16725 * lisp.h (lint_assume): New macro.
16726 * composite.c (composition_gstring_put_cache):
16727 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16729 * editfns.c, insdel.c:
16730 Omit unnecessary forward decls, to simplify future changes.
16732 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16734 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16736 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16737 Use much-faster test for byte-length change.
16738 Don't assume string byte-length fits in 'int'.
16739 Check that character arg fits in 'int'.
16740 (mapcar1): Declare byte as byte, for clarity.
16742 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16744 * fns.c (concat): Catch string overflow earlier.
16745 Do not rely on integer wraparound.
16747 * dispextern.h (struct it.overlay_strings_charpos)
16748 (struct it.selective): Now EMACS_INT, not int.
16749 * xdisp.c (forward_to_next_line_start)
16750 (back_to_previous_visible_line_start)
16751 (reseat_at_next_visible_line_start, next_element_from_buffer):
16752 Don't arbitrarily truncate the value of 'selective' to int.
16754 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16756 * composite.c: Don't truncate sizes to 'int'.
16757 (composition_gstring_p, composition_reseat_it)
16758 (composition_adjust_point): Use EMACS_INT, not int.
16759 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16760 not EMACS_UINT, for indexes.
16762 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16764 * buffer.c: Include <verify.h>.
16765 (struct sortvec.priority, struct sortstr.priority):
16766 Now EMACS_INT, not int.
16767 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16768 (struct sortstr.size, record_overlay_string)
16769 (struct sortstrlist.size, struct sortlist.used):
16770 Don't truncate size to int.
16771 (record_overlay_string): Check for size-calculation overflow.
16772 (init_buffer_once): Check at compile-time, not run-time.
16774 2011-06-22 Jim Meyering <meyering@redhat.com>
16776 Don't leak an XBM-image-sized buffer
16777 * image.c (xbm_load): Free the image buffer after using it.
16779 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16782 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16783 that Sun C diagnosed.
16784 * fns.c (secure_hash): Fix pointer signedness issue.
16785 * intervals.c (static_offset_intervals): New function.
16786 (offset_intervals): Use it.
16788 2011-06-21 Leo Liu <sdl.web@gmail.com>
16791 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16794 * fns.c (secure_hash): Rename from crypto_hash_function and change
16795 the first arg to accept symbols.
16796 (Fsecure_hash): New primitive.
16797 (syms_of_fns): New symbols.
16799 2011-06-20 Deniz Dogan <deniz@dogan.se>
16801 * process.c (Fset_process_buffer): Clarify return value in
16804 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16806 * dispnew.c (add_window_display_history): Use BVAR.
16808 * xdisp.c (debug_method_add): Use BVAR.
16809 (check_window_end, dump_glyph_matrix, dump_glyph)
16810 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16812 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16815 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16816 check till after the cache is created in init_frame_faces.
16818 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16820 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16822 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16824 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16825 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16826 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16828 Improve buffer-overflow checking (Bug#8873).
16829 * fileio.c (Finsert_file_contents):
16830 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16831 Remove the old (too-loose) buffer overflow checks.
16832 They weren't needed, since make_gap checks for buffer overflow.
16833 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16834 The old code merely checked for Emacs fixnum overflow, and relied
16835 on undefined (wraparound) behavior. The new code avoids undefined
16836 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16838 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16839 Tune. Don't use wider integers than needed. Don't use alloca.
16840 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16842 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16844 * insdel.c, lisp.h (buffer_overflow): New function.
16845 (insert_from_buffer_1, replace_range, replace_range_2):
16846 * insdel.c (make_gap_larger):
16847 * editfns.c (Finsert_char):
16848 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16850 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16852 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16854 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16856 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16857 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16859 * fileio.c: Don't assume EMACS_INT fits in off_t.
16860 (emacs_lseek): New static function.
16861 (Finsert_file_contents, Fwrite_region): Use it.
16862 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16864 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16866 * fns.c: Don't overflow int when computing a list length.
16867 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16868 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16869 truncation on 64-bit hosts. Check for QUIT every
16870 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16871 faster and is responsive enough.
16872 (Flength): Report an error instead of overflowing an integer.
16873 (Fsafe_length): Return a float if the value is not representable
16874 as a fixnum. This shouldn't happen except in contrived situations.
16875 (Fnthcdr, Fsort): Don't assume list length fits in int.
16876 (Fcopy_sequence): Don't assume vector length fits in int.
16878 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16879 (header_size, word_size): New constants.
16880 (allocate_vectorlike): Don't check size overflow here.
16881 (allocate_vector): Check it here instead, since this is the only
16882 caller of allocate_vectorlike that could cause overflow.
16883 Check that the new vector's length is representable as a fixnum.
16885 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16886 The previous code was bogus. For example, next_almost_prime (32)
16887 returned 39, which is undesirable as it is a multiple of 3; and
16888 next_almost_prime (24) returned 25, which is a multiple of 5 so
16889 why was the code bothering to check for multiples of 7?
16891 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16893 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16895 Variadic C functions now count arguments with ptrdiff_t.
16896 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16897 Back then I didn't know that the Emacs coding style prefers signed int.
16898 Also, in the meantime I found a few more instances where arguments
16899 were being counted with int, which may truncate counts on 64-bit
16900 machines, or EMACS_INT, which may be unnecessarily wide.
16901 * lisp.h (struct Lisp_Subr.function.aMANY)
16902 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16903 Arg counts are now ptrdiff_t, not size_t.
16904 All variadic functions and their callers changed accordingly.
16905 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16906 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16907 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16908 * callint.c (Fcall_interactively): Check arg count for overflow,
16909 to avoid potential buffer overrun. Use signed char, not 'int',
16910 for 'varies' array, so that we needn't bother to check its size
16911 calculation for overflow.
16912 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16913 * eval.c (apply_lambda):
16914 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16915 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16916 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16918 * callint.c (Fcall_interactively): Don't use index var as event count.
16920 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16921 * mem-limits.h (SIZE): Remove; no longer used.
16923 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16925 Remove unnecessary casts.
16926 * xterm.c (x_term_init):
16927 * xfns.c (x_set_border_pixel):
16928 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16929 These aren't needed now that we assume ANSI C.
16931 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16932 It's more likely to cause problems (due to unsigned overflow)
16935 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16937 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16939 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16941 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16943 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16945 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16947 GLYPH_CODE_FACE returns EMACS_INT, not int.
16948 * dispextern.h (merge_faces):
16949 * xfaces.c (merge_faces):
16950 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16951 Don't assume EMACS_INT fits in int.
16953 * character.h (CHAR_VALID_P): Remove unused parameter.
16954 * fontset.c, lisp.h, xdisp.c: All uses changed.
16956 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16958 * fns.c (concat): Minor tuning based on overflow analysis.
16959 This doesn't fix any bugs. Use int to hold character, instead
16960 of constantly refetching from Emacs object. Use XFASTINT, not
16961 XINT, for value known to be a character. Don't bother comparing
16962 a single byte to 0400, as it's always less.
16964 * floatfns.c (Fexpt):
16965 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16967 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16970 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16972 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16973 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16974 incorrectly succeed when S was a string, because 4294967386 was
16975 truncated before it was used.
16977 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16978 Otherwise, an out-of-range integer could cause undefined behavior
16981 * composite.c: Use int, not EMACS_INT, for characters.
16982 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16983 EMACS_INT, for values that are known to be in character range.
16984 This doesn't fix any bugs but is the usual style inside Emacs and
16985 may generate better code on 32-bit machines.
16987 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16988 This is for reasons similar to the recent CHAR_STRING fix.
16989 * charset.c (Fencode_char): Check that character arg is actually
16990 a character. Pass an int to ENCODE_CHAR.
16991 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16992 wider than 'int', as a compile-time check to prevent future regressions
16995 * character.c (char_string): Remove unnecessary casts.
16997 Make sure a 64-bit char is never passed to CHAR_STRING.
16998 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16999 by silently ignoring the top 32 bits, allowing some values
17000 that were far too large to be valid characters.
17001 * character.h: Include <verify.h>.
17002 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17003 arguments are no wider than unsigned, as a compile-time check
17004 to prevent future regressions in this area.
17006 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17007 (Fsubst_char_in_region):
17009 * xdisp.c (decode_mode_spec_coding):
17010 Adjust to CHAR_STRING's new requirement.
17011 * editfns.c (Finsert_char, Fsubst_char_in_region):
17012 * fns.c (concat): Check that character args are actually
17013 characters. Without this test, these functions did the wrong
17014 thing with wildly out-of-range values on 64-bit hosts.
17016 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17017 These casts should not be needed on 32-bit hosts, either.
17018 * keyboard.c (read_char):
17019 * lread.c (Fload): Remove casts to unsigned.
17021 * lisp.h (UNSIGNED_CMP): New macro.
17022 This fixes comparison bugs on 64-bit hosts.
17023 (ASCII_CHAR_P): Use it.
17024 * casefiddle.c (casify_object):
17025 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17026 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17027 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17028 * dispextern.h (FACE_FROM_ID):
17029 * keyboard.c (read_char): Use UNSIGNED_CMP.
17031 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17032 not to EMACS_INT, to avoid GCC warning.
17034 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17036 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17037 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17038 isn't needed on 32-bit machines.
17040 * buffer.c (Fgenerate_new_buffer_name):
17041 Use EMACS_INT for count, not int.
17042 (advance_to_char_boundary): Return EMACS_INT, not int.
17044 * data.c (Qcompiled_function): Now static.
17046 * window.c (window_body_lines): Now static.
17048 * image.c (gif_load): Rename local to avoid shadowing.
17050 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17051 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17052 * alloc.c (make_save_value): Integer argument is now of type
17053 ptrdiff_t, not int.
17054 (mark_object): Use ptrdiff_t, not int.
17055 * lisp.h (pD): New macro.
17056 * print.c (print_object): Use it.
17058 * alloc.c: Use EMACS_INT, not int, to count objects.
17059 (total_conses, total_markers, total_symbols, total_vector_size)
17060 (total_free_conses, total_free_markers, total_free_symbols)
17061 (total_free_floats, total_floats, total_free_intervals)
17062 (total_intervals, total_strings, total_free_strings):
17063 Now EMACS_INT, not int. All uses changed.
17064 (Fgarbage_collect): Compute overall total using a double, so that
17065 integer overflow is less likely to be a problem. Check for overflow
17066 when converting back to an integer.
17067 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17068 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17069 These were 'int' variables that could overflow on 64-bit hosts;
17070 they were never used, so remove them instead of repairing them.
17071 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17072 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17073 Previously, this ceilinged at INT_MAX, but that doesn't work on
17075 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17077 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17078 (allocate_vectorlike): Check for ptrdiff_t overflow.
17079 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17080 when a (possibly-narrower) signed value would do just as well.
17081 We prefer using signed arithmetic, to avoid comparison confusion.
17083 * alloc.c: Catch some string size overflows that we were missing.
17084 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17085 for convenience in STRING_BYTES_MAX.
17086 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17087 The definition here is exact; the one in lisp.h was approximate.
17088 (allocate_string_data): Check for string overflow. This catches
17089 some instances we weren't catching before. Also, it catches
17090 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17091 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17092 and ptrdiff_t and EMACS_INT are both 64 bits.
17094 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17095 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17096 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17098 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17100 * alloc.c (Fmake_string): Check for out-of-range init.
17102 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17104 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17106 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17108 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

17111 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17112 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17113 (style_changed_cb): Call update_theme_scrollbar_width and call
17114 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17115 all frames (Bug#8505).
17116 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17117 Call gtk_window_set_resizable if HAVE_GTK3.

17119 and height if HAVE_GTK3 (Bug#8505).
17120 (scroll_bar_width_for_theme): New variable.
17121 (update_theme_scrollbar_width): New function.
17122 (xg_get_default_scrollbar_width): Move code to
17123 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

17126 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17128 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

17132 * frame.c (make_frame): Call other_buffer_safely instead of
17135 * window.c (temp_output_buffer_show): Call display_buffer with
17136 second argument Vtemp_buffer_show_specifiers and reset latter
17137 immediately after the call.
17138 (Vtemp_buffer_show_specifiers): New variable.
17139 (auto_window_vscroll_p, next_screen_context_lines)
17140 (Vscroll_preserve_screen_position): Remove leading asterisks from

17691 (display_prop_intangible_p): Reimplement to call
17692 handle_display_spec instead of single_display_spec_intangible_p.

17704 value of a `display' property is a "replacing spec".
17705 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17706 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

17736 * gnutls.c: Use Emacs's memory allocators.
17737 Without this change, the gnutls library would invoke malloc etc.
17738 directly, which causes problems on non-SYNC_INPUT hosts, and which
17739 runs afoul of improving memory_full behavior. (Bug#8761)
17740 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17741 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17742 xfree instead of the default malloc, realloc, free.
17743 (Fgnutls_boot): No need to check for memory allocation failure,
17744 since xmalloc does that for us.

17767 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17768 * alloc.c (allocate_vectorlike):
17769 Check for overflow in vector size calculations.
17770 * ccl.c (ccl_driver):
17771 Check for overflow when converting EMACS_INT to int.

17773 need to be updated by these changes.
17774 * fns.c (make_hash_table, maybe_resize_hash_table):
17775 Check for integer overflow with large hash tables.
17776 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17777 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17778 (SXHASH_REDUCE): New macro.
17779 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17780 Use it instead of discarding useful hash info with large hash values.
17781 (sxhash_float): New function.
17782 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17783 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17784 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17785 Rewrite to use FIXNUM_BITS, as this simplifies things.
17786 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17787 Adjust signatures to match updated version of code.
17788 (consing_since_gc): Now EMACS_INT, since a single hash table can
17789 use more than INT_MAX bytes.

17817 only when CANNOT_DUMP is defined.
17818 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17820 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17822 * dispnew.c (add_window_display_history): Use const for the string
17823 pointer. Remove declaration, not needed.
17825 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17827 Use 'inline', not 'INLINE'.
17828 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17829 * alloc.c, fontset.c (INLINE): Remove.
17830 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17831 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17832 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17833 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17834 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17836 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17838 Make it possible to run ./temacs.
17840 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17841 syms_of_callproc does the same thing. Remove test for
17842 "initialized", do it in the caller.
17843 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17845 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17847 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17848 (read_minibuf): Use get_minibuffer.
17849 (syms_of_minibuf): Use DEFSYM.
17850 (Qmetadata): New var.
17851 * data.c (Qbuffer): Don't make it static.
17852 (syms_of_data): Use DEFSYM.
17854 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17856 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17857 (CCL_CODE_MIN): New macro.
17859 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17861 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17863 * eval.c (Qdebug): Now static.
17864 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17865 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17866 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17868 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17870 * image.c: Various fixes to ImageMagick code comments.
17871 (Fimagemagick_types): Doc fix.
17873 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17875 Minor fixes prompted by GCC 4.6.0 warnings.
17877 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17879 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17880 (x_clipboard_manager_save_all): Move extern decl to ...
17881 * xterm.h: ... here, so that it can be checked for consistency.
17883 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17885 * xselect.c (x_clipboard_manager_save_frame)
17886 (x_clipboard_manager_save_all): New functions.
17887 (Fx_clipboard_manager_save): Lisp function deleted.
17889 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17890 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17892 * xterm.h: Update prototype.
17894 2011-05-28 William Xu <william.xwl@gmail.com>
17896 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17897 exiting (Bug#8239).
17899 2011-05-28 Jim Meyering <meyering@redhat.com>
17901 Avoid a sign-extension bug in crypto_hash_function.
17902 * fns.c (to_uchar): Define.
17903 (crypto_hash_function): Use it to convert some newly-signed
17904 variables to unsigned, to avoid sign-extension bugs. For example,
17905 without this change, (md5 "truc") would evaluate to
17906 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17907 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17908 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17910 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17912 Integer overflow fixes.
17914 * dbusbind.c: Serial number integer overflow fixes.
17915 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17916 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17917 to hold a serial number that is too large for a fixnum.
17918 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17919 Check for serial numbers out of range. Decode any serial number
17920 that was so large that it became a float. (Bug#8722)
17922 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17923 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17924 Use XFASTINT rather than XUINT when numbers are nonnegative.
17925 (xd_append_arg, Fdbus_method_return_internal):
17926 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17927 arguments, check that Lisp number is nonnegative, rather than
17928 silently wrapping negative numbers around. (Bug#8722)
17929 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17932 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17934 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17936 ccl: Add integer overflow checks.
17937 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17938 (IN_INT_RANGE): New macros.
17939 (ccl_driver): Use them to check for integer overflow when
17940 decoding a CCL program. Many of the new checks are whether XINT (x)
17941 fits in int; it doesn't always, on 64-bit hosts. The new version
17942 doesn't catch all possible integer overflows, but it's an
17943 improvement. (Bug#8719)
17945 * alloc.c (make_event_array): Use XINT, not XUINT.
17946 There's no need for unsigned here.
17948 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17949 This follows up to the 2011-05-06 change that substituted uintptr_t
17950 for EMACS_INT. This case wasn't caught back then.
17952 Rework Fformat to avoid integer overflow issues.
17953 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17954 now (part of C89). Include <verify.h>.
17955 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17956 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17957 (Fformat): Avoid the prepass trying to compute sizes; it was only
17958 approximate and thus did not catch overflow reliably. Instead, walk
17959 through the format just once, formatting and computing sizes as we go,
17960 checking for integer overflow at every step, and allocating a larger
17961 buffer as needed. Keep track separately whether the format is
17962 multibyte. Keep only the most-recently calculated precision, rather
17963 than them all. Record whether each argument has been converted to
17964 string. Use EMACS_INT, not int, for byte and char and arg counts.
17965 Support field widths and precisions larger than INT_MAX. Avoid
17966 sprintf's undefined behavior with conversion specifications such as %#d
17967 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17968 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17969 formatting out-of-range floating point numbers with int
17970 formats. (Bug#8668)
17972 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17974 * data.c: Avoid integer truncation in expressions involving floats.
17975 * data.c: Include <intprops.h>.
17976 (arith_driver): When there's an integer overflow in an expression
17977 involving floating point, convert the integers to floating point
17978 so that the resulting value does not suffer from catastrophic
17979 integer truncation. For example, on a 64-bit host (* 4
17980 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17981 Do not rely on undefined behavior after integer overflow.
17983 merge count_size_as_multibyte, parse_str_to_multibyte
17984 * character.c, character.h (count_size_as_multibyte):
17985 Rename from parse_str_to_multibyte; all uses changed.
17986 Check for integer overflow.
17987 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17988 since it's now a duplicate of the other. This is more of
17989 a character than a buffer op, so better that it's in character.c.
17990 * fns.c, print.c: Adjust to above changes.
17992 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17994 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17996 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17998 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17999 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18000 (x_clipboard_manager_save): Now static.
18001 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18003 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18004 (crypto_hash_function): Now static.
18005 Fix pointer signedness problems. Avoid unnecessary initializations.
18007 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18009 * termhooks.h (Vselection_alist): Make it terminal-local.
18011 * terminal.c (create_terminal): Initialize it.
18013 * xselect.c: Support for clipboard managers.
18014 (Vselection_alist): Move to termhooks.h as terminal-local var.
18015 (LOCAL_SELECTION): New macro.
18016 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18017 (symbol_to_x_atom): Remove gratuitous arg.
18018 (x_handle_selection_request, lisp_data_to_selection_data)
18019 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18020 (x_own_selection, x_get_local_selection, x_convert_selection):
18021 New arg, specifying work frame. Use terminal-local Vselection_alist.
18022 (some_frame_on_display): Delete unused function.
18023 (Fx_own_selection_internal, Fx_get_selection_internal)
18024 (Fx_disown_selection_internal, Fx_selection_owner_p)
18025 (Fx_selection_exists_p): New optional frame arg.
18026 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18027 (x_handle_selection_clear): Don't treat other terminals with the
18028 same keyboard specially. Use the terminal-local Vselection_alist.
18029 (x_clear_frame_selections): Use Frun_hook_with_args.
18031 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18033 * xterm.h: Add support for those atoms.
18035 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18037 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18038 (converted_selections, conversion_fail_tag): New global variables.
18039 (x_selection_request_lisp_error): Free the above.
18040 (x_get_local_selection): Remove unnecessary code.
18041 (x_reply_selection_request): Args changed; handle arbitrary array
18042 of converted selections stored in converted_selections.
18043 Separate the XChangeProperty and SelectionNotify steps.
18044 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18045 (x_convert_selection): New function.
18046 (x_handle_selection_event): Simplify.
18047 (x_get_foreign_selection): Don't ignore incoming requests while
18048 waiting for an answer; this will fail when we implement
18049 SAVE_TARGETS, and seems unnecessary anyway.
18050 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18051 (Vx_sent_selection_functions): Doc fix.
18053 2011-05-26 Leo Liu <sdl.web@gmail.com>
18055 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18057 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18059 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18061 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18062 for fringe update if it has periodic bitmap.
18063 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18064 and fringe_bitmap_periodic_p.
18066 * fringe.c (get_fringe_bitmap_data): New function.
18067 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18068 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18069 row. Mark glyph row for fringe update if periodicity changed.
18071 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18072 for fringe update unless it has periodic bitmap.
18074 2011-05-25 Kenichi Handa <handa@m17n.org>
18076 * xdisp.c (get_next_display_element): Set correct it->face_id for
18077 a static composition.
18079 2011-05-24 Leo Liu <sdl.web@gmail.com>
18082 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18084 * fns.c (crypto_hash_function, Fsha1): New function.
18085 (Fmd5): Use crypto_hash_function.
18086 (syms_of_fns): Add Ssha1.
18088 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18090 * gnutls.c: Remove unused macros.
18091 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18092 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18093 Remove macros that are defined and never used.
18094 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18096 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18098 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18099 (Fx_get_selection_internal): Minor cleanup.
18100 (Fx_own_selection_internal): Rename arguments for consistency with
18103 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18105 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18107 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18109 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18111 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18113 * dispnew.c (scrolling_window): Don't exclude the case that the
18114 last enabled row in the desired matrix touches the bottom boundary.
18116 2011-05-21 Glenn Morris <rgm@gnu.org>
18118 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18119 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18120 and add some more files.
18122 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18124 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18125 report_file_error introduced by the change from 2011-05-07.
18127 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18129 * systime.h (Time): Define only if emacs is defined.
18130 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18131 where the include path doesn't have X11/X.h by default. See
18132 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18134 2011-05-20 Kenichi Handa <handa@m17n.org>
18136 * composite.c (find_automatic_composition): Fix previous change.
18138 2011-05-20 Glenn Morris <rgm@gnu.org>
18140 * lisp.mk: New file, split from Makefile.in.
18141 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18142 (shortlisp): Remove.
18143 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18145 2011-05-19 Glenn Morris <rgm@gnu.org>
18147 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18148 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18149 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18150 (lisp): Set the order to that of loadup.el.
18151 (shortlisp): Make it a copy of $lisp.
18152 (SOME_MACHINE_LISP): Remove.
18153 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18154 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18156 2011-05-18 Kenichi Handa <handa@m17n.org>
18158 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18159 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18160 (find_automatic_composition): Mostly rewrite for efficiency.
18162 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18164 * makefile.w32-in: Update dependencies.
18166 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18168 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18169 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18171 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18173 Fix some integer overflow issues, such as string length overflow.
18175 * insdel.c (count_size_as_multibyte): Check for string overflow.
18177 * character.c (lisp_string_width): Check for string overflow.
18178 Use EMACS_INT, not int, for string indexes and lengths; in
18179 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18180 the resulting string length overflows an EMACS_INT; instead,
18181 report a string overflow if no precision given. When checking for
18182 precision exhaustion, use a check that cannot possibly have
18183 integer overflow. (Bug#8675)
18184 * character.h (lisp_string_width): Adjust to new signature.
18186 * alloc.c (string_overflow): New function.
18187 (Fmake_string): Use it. This doesn't change behavior, but saves
18188 a few bytes and will simplify future changes.
18189 * character.c (string_escape_byte8): Likewise.
18190 * lisp.h (string_overflow): New decl.
18192 Fixups, following up to the user-interface timestamp change.
18193 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18194 for UI timestamps, instead of unsigned long.
18195 * msdos.c (mouse_get_pos): Likewise.
18196 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18197 * w32gui.h (Time): Define by including "systime.h" rather than by
18198 declaring it ourselves. (Bug#8664)
18200 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18201 * image.c (clear_image_cache): Likewise.
18203 * term.c (term_mouse_position): Don't assume time_t wraparound.
18205 Be more systematic about user-interface timestamps.
18206 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18207 and sometimes 'EMACS_UINT', to represent these timestamps.
18208 This change causes it to use 'Time' uniformly, as that's what X uses.
18209 This makes the code easier to follow, and makes it easier to catch
18210 integer overflow bugs such as Bug#8664.
18211 * frame.c (Fmouse_position, Fmouse_pixel_position):
18212 Use Time, not unsigned long, for user-interface timestamps.
18213 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18214 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18215 * keyboard.h (last_event_timestamp): Likewise.
18216 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18217 * menu.h (xmenu_show): Likewise.
18218 * term.c (term_mouse_position): Likewise.
18219 * termhooks.h (struct input_event.timestamp): Likewise.
18220 (struct terminal.mouse_position_hook): Likewise.
18221 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18222 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18223 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18224 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18225 what it was before.
18226 * menu.h, termhooks.h: Include "systime.h", for Time.
18228 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18229 Don't assume that the difference between two unsigned long values
18230 can fit into an integer. At this point, we know button_down_time
18231 <= event->timestamp, so the difference must be nonnegative, so
18232 there's no need to cast the result if double-click-time is
18233 nonnegative, as it should be; check that it's nonnegative, just in
18234 case. This bug is triggered when events are more than 2**31 ms
18235 apart (about 25 days). (Bug#8664)
18237 * xselect.c (last_event_timestamp): Remove duplicate decl.
18238 (x_own_selection): Remove needless cast to unsigned long.
18240 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18241 that always fit in int. Use a sentinel instead of a counter, to
18242 avoid a temp and to allay GCC's concerns about possible int overflow.
18243 * frame.h (struct frame): Use int for menu_bar_items_used
18244 instead of EMACS_INT, since it always fits in int.
18246 * menu.c (grow_menu_items): Check for int overflow.
18248 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18250 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18251 Before, the code was not consistent. These values cannot exceed
18252 2**31 - 1 so there's no need to make them unsigned.
18253 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18254 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18255 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18257 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18259 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18260 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18261 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18262 presumably because the widths might not match.
18264 * window.c (size_window): Avoid needless test at loop start.
18266 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18268 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18270 2011-05-12 Drew Adams <drew.adams@oracle.com>
18272 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18274 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18276 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18277 `width' to `bar_area_x' and `bar_area_width', respectively.
18278 (x_scroll_run): Take account of fringe background extension.
18280 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18281 Rename local vars `left' and `width' to `bar_area_x' and
18282 `bar_area_width', respectively.
18283 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18284 background extension.
18286 2011-05-10 Jim Meyering <meyering@redhat.com>
18288 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18290 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18292 * image.c (Finit_image_library): Return t for built-in image types,
18293 like pbm and xbm. (Bug#8640)
18295 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18297 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18299 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18301 * w32console.c (Fset_screen_color): Doc fix.
18302 (Fget_screen_color): New function.
18303 (syms_of_ntterm): Defsubr it.
18305 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18306 unlink the temporary file if Fcall_process didn't create it in the
18308 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18309 child process will be redirected to a file specified with `:file'.
18310 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18311 cue to call_process_cleanup not to close that handle.
18313 2011-05-07 Ben Key <bkey76@gmail.com>
18315 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18316 one of two shell specific rules, either bootstrap-temacs-CMD or
18317 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18318 to the previous implementation of the bootstrap-temacs rule.
18319 The bootstrap-temacs-CMD rule is similar to the previous
18320 implementation of the bootstrap-temacs rule except that it
18321 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18324 These changes, along with some changes to nt/configure.bat,
18325 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18326 earlier fix to add support for --cflags and --ldflags options
18327 that include quotes so that it works whether make uses cmd or
18330 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18332 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18333 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18335 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18336 a string. Handle both cases.
18337 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18338 (Fdbus_register_method): Use Qinvalid_function.
18340 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18342 * makefile.w32-in: Update dependencies.
18343 (LISP_H): Add inttypes.h and stdin.h.
18344 (PROCESS_H): Add unistd.h.
18346 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18348 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18349 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18351 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18353 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18355 * term.c (vfatal): Remove stray call to va_end.
18356 It's not needed and the C Standard doesn't allow it here anyway.
18358 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18359 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18361 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18364 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18366 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18368 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18370 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18372 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18374 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18375 * charset.c (Fdefine_charset_internal): Don't initialize
18376 charset.code_space[15]. The value was garbage, on hosts with
18377 32-bit int (Bug#8600).
18379 * lread.c (read_integer): Be more consistent with string-to-number.
18380 Use string_to_number to do the actual conversion; this avoids
18381 rounding errors and fixes some other screwups. Without this fix,
18382 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18383 (digit_to_number): Move earlier, for benefit of read_integer.
18384 Return -1 if the digit is out of range for the base, -2 if it is
18385 not a digit in any supported base. (Bug#8602)
18387 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18389 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18390 to match comment at start of function. This also removes a
18391 GCC warning about overflow in a 32+64-bit port.
18393 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18395 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18396 Reported by Stefan Monnier in
18397 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18398 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18399 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18401 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18402 (EMACS_UINTPTR): Likewise, with uintptr_t.
18404 * lisp.h: Prefer 64-bit EMACS_INT if available.
18405 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18406 on 32-bit hosts that have 64-bit int, so that they can access
18408 However, temporarily disable this change unless the temporary
18409 symbol WIDE_EMACS_INT is defined.
18411 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18413 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18414 This removes an assumption that EMACS_INT and long are the same
18415 width as pointers. The assumption is true for Emacs porting targets
18416 now, but we want to make other targets possible.
18417 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18418 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18419 In the rest of the code, change types of integers that hold casted
18420 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18421 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18422 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18423 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18424 No need to cast type when ORing.
18425 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18426 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18427 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18428 assume EMACS_INT is the same width as char *.
18429 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18430 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18431 Remove no-longer-needed casts.
18432 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18433 (xg_tool_bar_help_callback, xg_make_tool_item):
18434 Use EMACS_INTPTR to hold an integer
18435 that will be cast to void *; this can avoid a GCC warning
18436 if EMACS_INT is not the same width as void *.
18437 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18438 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18439 (current_message_1, set_message_1):
18440 Use a local to convert to proper width without a cast.
18441 * xmenu.c (dialog_selection_callback): Likewise.
18443 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18444 Also, don't assume VALBITS / RAND_BITS is less than 5,
18445 and don't rely on undefined behavior when shifting a 1 left into
18447 * lisp.h (get_random): Change signature to match.
18449 * lread.c (hash_string): Use size_t, not int, for hash computation.
18450 Normally we prefer signed values; but hashing is special, because
18451 it's better to use unsigned division on hash table sizes so that
18452 the remainder is nonnegative. Also, size_t is the natural width
18453 for hashing into memory. The previous code used 'int', which doesn't
18454 retain enough info to hash well into very large tables.
18455 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18457 * dbusbind.c: Don't possibly lose pointer info when converting.
18458 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18459 Use XPNTR rather than XHASH, so that the high-order bits of
18460 the pointer aren't lost when converting through void *.
18462 * eval.c (Fautoload): Don't double-shift a pointer.
18464 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18466 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18468 * gnutls.c (DEF_GNUTLS_FN):
18469 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18471 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18473 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18476 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18478 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18479 New version that can reserve upto 2GB of heap space.
18481 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18483 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

18487 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18488 `gnutls_certificate_set_x509_key_file'.
18490 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18492 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18493 Update dependencies.
18495 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18497 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18498 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18499 Remove unused parameter `fildes'.
18500 * process.c (read_process_output, send_process): Don't pass it.
18502 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18504 Fix previous change: the library cache is defined in w32.c.
18505 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18506 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18508 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18510 Implement dynamic loading of GnuTLS on Windows.
18512 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18513 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18514 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18517 * gnutls.c (Qgnutls_dll): Define.
18518 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18519 (gnutls_*): Declare function pointers.
18520 (init_gnutls_functions): New function to initialize function pointers.

18523 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18524 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18525 (emacs_gnutls_write, emacs_gnutls_read)
18526 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18527 (Fgnutls_available_p): New function.
18528 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

18535 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18536 (w32_delayed_load): Move to w32.c.
18538 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18540 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18541 (w32_delayed_load): Move from image.c. When loading a library, record
18542 its filename in the :loaded-from property of the library id.
18543 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18544 Initialize and staticpro them.
18545 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18547 * process.c: Include lisp.h before w32.h, not after.
18548 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18549 instead of gnutls_record_check_pending.
18551 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18553 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18555 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18556 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18559 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18561 * xterm.c (x_set_frame_alpha): Do not set property on anything

18584 * sysdep.c (wait_for_termination_1): Make static.
18585 (wait_for_termination, interruptible_wait_for_termination):
18586 Move after wait_for_termination_1.
18588 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18590 * sysdep.c (interruptible_wait_for_termination): New function
18591 which is like wait_for_termination, but allows keyboard
18594 * callproc.c (Fcall_process): Add (:file "file") as an option for
18596 (Fcall_process_region): Ditto.
18598 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18600 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18601 rather than `XVECTOR (FOO)->size'.
18603 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18604 inttypes.h, as a gnulib replacement is used if it not available in
18607 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18609 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18610 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18611 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18613 * coding.c (coding_alloc_by_realloc): Error out if destination
18614 will grow beyond MOST_POSITIVE_FIXNUM.
18615 (decode_coding_emacs_mule): Abort if there isn't enough place in

18628 * window.c (window_scroll_line_based): Use a marker instead of
18629 simple variables to record original value of point. (Bug#7952)
18631 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18632 produced by %s or %c overflows available buffer space. (Bug#8545)
18634 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18636 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18637 (SIZE_MAX): Move defn after all includes, as they might #define it.
18639 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18641 * w32.c (init_environment): Warn about defaulting HOME to C:\.

18665 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18667 * makefile.w32-in: Update dependencies.

18671 Improve `doprnt' and its usage. (Bug#8545)
18672 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18673 `format_end'. Remove support for %l as a conversion specifier.
18674 Don't use xrealloc. Improve diagnostics when the %l size modifier
18675 is used. Update the commentary.
18677 * eval.c (verror): Simplify calculation of size_t.
18679 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18682 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18684 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18687 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18689 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18690 This makes this file independent of the recent pseudovector change.
18692 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18694 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18696 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18697 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18698 Remove unused local.
18699 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18701 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18702 GCC 4.6.0 optimizes based on type-based alias analysis.
18703 For example, if b is of type struct buffer * and v of type struct
18704 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18705 != &v->size, and therefore "v->size = 1; b->size = 2; return
18706 v->size;" must therefore return 1. This assumption is incorrect
18707 for Emacs, since it type-puns struct Lisp_Vector * with many other
18708 types. To fix this problem, this patch adds a new type struct
18709 vectorlike_header that documents the constraints on layout of vectors
18710 and pseudovectors, and helps optimizing compilers not get fooled
18711 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18712 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18713 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18715 (XSETPVECTYPE): Rewrite in terms of new macro.
18716 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18717 This is a bit clearer, and further avoids the possibility of
18718 undesirable aliasing.
18719 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18720 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18721 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18722 since Lisp_Subr is a special case (no "next" field).
18723 (ASIZE): Now uses header.size rather than size.
18724 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18725 to avoid the hassle of writing XVECTOR (foo)->header.size.
18726 (struct vectorlike_header): New type.
18727 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18728 object, to help avoid aliasing.
18729 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18730 (SUBRP): Likewise, since Lisp_Subr is a special case.
18731 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18732 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18733 (struct Lisp_Hash_Table): Combine first two members into a single
18734 struct vectorlike_header member. All uses of "size" and "next" members
18735 changed to be "header.size" and "header.next".
18736 * buffer.h (struct buffer): Likewise.
18737 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18738 * frame.h (struct frame): Likewise.
18739 * process.h (struct Lisp_Process): Likewise.
18740 * termhooks.h (struct terminal): Likewise.
18741 * window.c (struct save_window_data, struct saved_window): Likewise.
18742 * window.h (struct window): Likewise.
18743 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18744 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18745 * buffer.c (init_buffer_once): Likewise.
18746 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18748 * process.c (Fformat_network_address): Use local var for size,
18751 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18753 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18754 * data.c (atof): Remove decl; no longer used or needed.
18755 (digit_to_number): Move to lread.c.
18756 (Fstring_to_number): Use new string_to_number function, to be
18757 consistent with how the Lisp reader treats infinities and NaNs.
18758 Do not assume that floating-point numbers represent EMACS_INT
18759 without losing information; this is not true on most 64-bit hosts.
18760 Avoid double-rounding errors, by insisting on integers when
18761 parsing non-base-10 numbers, as the documentation specifies.
18762 * lisp.h (string_to_number): New decl, replacing ...
18763 (isfloat_string): Remove.
18764 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18765 (read1): Do not accept +. and -. as integers; this
18766 appears to have been a coding error. Similarly, do not accept
18767 strings like +-1e0 as floating point numbers. Do not report
18768 overflow for integer overflows unless the base is not 10 which
18769 means we have no simple and reliable way to continue.
18770 Break out the floating-point parsing into a new
18771 function string_to_number, so that Fstring_to_number parses
18772 floating point numbers consistently with the Lisp reader.
18773 (digit_to_number): Move here from data.c. Make it static inline.
18774 (E_CHAR, EXP_INT): Remove, replacing with ...
18775 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18776 (string_to_number): New function, replacing isfloat_string.
18777 This function checks for valid syntax and produces the resulting
18778 Lisp float number too. Rework it so that string-to-number
18779 no longer mishandles examples like "1.0e+". Use strtoumax,
18780 so that overflow for non-base-10 numbers is reported only when
18781 there's no portable and simple way to convert to floating point.
18783 * textprop.c (set_text_properties_1): Rewrite for clarity,
18784 and to avoid GCC warning about integer overflow.
18786 * intervals.h (struct interval): Use EMACS_INT for members
18787 where EMACS_UINT might cause problems. See
18788 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18789 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18790 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18792 (offset_intervals): Tell GCC not to worry about length overflow
18793 when negating a negative length.
18795 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18796 (overrun_check_free): Likewise.
18798 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18799 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18802 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18803 (gnutls_make_error): Rename local to avoid shadowing.
18804 (gnutls_emacs_global_deinit): ifdef out; not used.
18805 (Fgnutls_boot): Use const for pointer to readonly storage.
18806 Comment out unused local. Fix pointer signedness problems.
18808 * lread.c (openp): Don't stuff size_t into an 'int'.
18809 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18810 about possible signed overflow.
18812 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18813 (GDK_KEY_g): Don't define if already defined.
18814 (xg_prepare_tooltip): Avoid pointer signedness problem.
18815 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18817 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18818 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18820 * xfns.c (Fx_window_property): Simplify a bit,
18821 to make a bit faster and to avoid GCC 4.6.0 warning.
18822 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18824 * fns.c (internal_equal): Don't assume size_t fits in int.
18826 * alloc.c (compact_small_strings): Tighten assertion a little.
18828 Replace pEd with more-general pI, and fix some printf arg casts.
18829 * lisp.h (pI): New macro, generalizing old pEd macro to other
18830 conversion specifiers. For example, use "...%"pI"d..." rather
18831 than "...%"pEd"...".
18832 (pEd): Remove. All uses replaced with similar uses of pI.
18833 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18834 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18835 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18836 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18837 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18838 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18839 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18841 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18842 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18843 * print.c (safe_debug_print, print_object): Likewise.
18844 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18846 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18847 avoiding the 0 flag, which is not portable.
18848 * process.c (Fmake_network_process): Use pI to avoid cast.
18849 * region-cache.c (pp_cache): Likewise.
18850 * xdisp.c (decode_mode_spec): Likewise.
18851 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18852 behavior on 64-bit hosts with printf arg.
18853 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18854 (x_stop_queuing_selection_requests): Likewise.
18855 (x_get_window_property): Don't truncate byte count to an 'int'
18858 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18859 here, since it parses constructs like leading '-' and spaces,
18860 which are not wanted; and it overflows with large numbers.
18861 Instead, simply match F[0-9]+, which is what is wanted anyway.
18863 * alloc.c: Remove unportable assumptions about struct layout.
18864 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18865 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18866 (allocate_vectorlike, make_pure_vector): Use the new macros,
18867 plus offsetof, to remove unportable assumptions about struct layout.
18868 These assumptions hold on all porting targets that I know of, but
18869 they are not guaranteed, they're easy to remove, and removing them
18870 makes further changes easier.
18872 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18873 This doesn't fix a bug but makes the code clearer.
18874 (string_overrun_cookie): Now const. Use initializers that
18875 don't formally overflow signed char, to avoid warnings.
18876 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18877 can cause Emacs to crash when string overrun checking is enabled.
18878 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18879 multiple of sizeof (EMACS_INT); it need not be, if
18880 alignof(EMACS_INT) < sizeof (EMACS_INT).
18881 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18883 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18890 supposed to be handshaking. (Bug#8556)
18891 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18893 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

18903 * alloc.c (check_sblock, check_string_bytes)
18904 (check_string_free_list): Convert to standard C.
18906 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18908 * w32.c (emacs_gnutls_push): Fix typo.
18910 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18912 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18913 "cast to pointer from integer of different size".
18915 Improve doprnt and its use in verror. (Bug#8545)
18916 * doprnt.c (doprnt): Document the set of format control sequences
18917 supported by the function. Use SAFE_ALLOCA instead of always
18920 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18921 is one byte too soon. Don't use xrealloc; instead xfree and
18924 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18926 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18929 * gnutls.c: Renamed global_initialized to
18930 gnutls_global_initialized. Added internals for the
18931 :verify-hostname-error, :verify-error, and :verify-flags
18932 parameters of `gnutls-boot' and documented those parameters in the
18933 docstring. Start callback support.
18934 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18935 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18936 on error. Return error code.
18937 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18938 (emacs_gnutls_read): Likewise.
18939 (Fgnutls_boot): Return handshake error code.

19003 <char-direction-table>: Deleted.
19005 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19007 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19008 * doprnt.c: Include limits.h.
19009 (SIZE_MAX): New macro.
19010 (doprnt): Return a size_t value. 2nd arg is now size_t.
19011 Many local variables are now size_t instead of int or unsigned.
19012 Improve overflow protection. Support `l' modifier for integer
19013 conversions. Support %l conversion. Don't assume an EMACS_INT
19014 argument for integer conversions and for %c.
19016 * lisp.h (doprnt): Restore prototype.
19018 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19019 $(SRC)/character.h.
19021 * Makefile.in (base_obj): Add back doprnt.o.
19023 * deps.mk (doprnt.o): Add back prerequisites.
19024 (callint.o): Depend on character.h.
19026 * eval.c (internal_lisp_condition_case): Include the handler
19027 representation in the error message.
19028 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19029 when breaking from the loop.
19031 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19033 * callint.c (Fcall_interactively): When displaying error message
19034 about invalid control letter, pass the character's codepoint, not
19035 a pointer to its multibyte form. Improve display of the character
19036 in octal and display also its hex code.
19038 * character.c (char_string): Use %x to display the (unsigned)
19039 codepoint of an invalid character, to avoid displaying a bogus
19042 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19043 `error', not SYMBOL_NAME itself.
19045 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19046 character arguments to `error'.
19048 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19049 to `error' in error message about FINAL_CHAR argument. Make sure
19050 FINAL_CHAR is a character, and use %c when it is passed as
19051 argument to `error'.

19115 Define only if needed.
19117 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
19118 by pacifying GCC about it. Maybe it's time to retire it?
19119 * xfaces.c (USG, __TIMEVAL__): Likewise.
19121 * dispextern.h (struct redisplay_interface): Rename param
19122 to avoid shadowing.
19123 * termhooks.h (struct terminal): Likewise.
19124 * xterm.c (xembed_send_message): Likewise.
19126 * insdel.c (make_gap_smaller): Define only if
19127 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
19129 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
19132 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
19133 so that we aren't warned about unused symbols.

19586 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
19587 * ccl.c (Vccl_program_table): Now static.
19588 (check_ccl_update): Remove; unused.
19590 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
19591 * category.h: ... from here.
19592 * category.c (check_category_table, set_category_set): Now static.
19594 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
19595 * lisp.h: Remove these decls.
19597 * buffer.c (buffer_count): Remove unused var.
19599 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
19600 so that it's not optimized away.
19601 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
19602 * dispextern.h (bidi_dump_cached_states): Remove, since it's
19603 exported only to the debugger.
19605 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
19606 * atimer.h (run_all_atimers): Remove; not exported.
19608 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19609 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19610 was inaccessible from Lisp.
19611 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19612 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19614 alloc.c: Import and export fewer symbols, and remove unused items.
19615 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19617 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19618 it's not optimized away by whole-program optimization.
19619 (message_enable_multibyte, free_misc): Remove.
19620 (catchlist, handlerlist, mark_backtrace):
19621 Declare only if BYTE_MARK_STACK.
19622 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
19623 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
19624 (message_enable_multibyte): Remove decl.
19625 (free_misc, interval_free_list, float_block, float_block_index):

19627 (cons_free_list, last_marked_index):
19629 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
19630 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
19631 (mark_backtrace): Define only if BYTE_MARK_STACK.
19632 * xdisp.c (message_enable_multibyte): Now static.
19634 Declare Lisp_Object Q* variables to be 'static' if not exported.
19635 This makes it easier for human readers (and static analyzers)
19636 to see whether these variables are used from other modules.
19637 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
19638 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
19639 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

19642 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
19643 * xmenu.c, xselect.c:
19644 Declare Q* vars static if they are not used in other modules.
19645 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
19646 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
19647 Remove decls of unexported vars.
19648 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19650 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19652 Make Emacs functions such as Fatom 'static' by default.
19653 This makes it easier for human readers (and static analyzers)
19654 to see whether these functions can be called from other modules.
19655 DEFUN now defines a static function. To make the function external
19656 so that it can be used in other C modules, use the new macro DEFUE.
19657 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19658 (Finit_image_library):
19659 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
19660 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19661 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19662 Remove decls, since these functions are now static.
19663 (Funintern, Fget_internal_run_time): New decls, since these functions
19664 were already external.
19666 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19667 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
19668 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

19673 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19674 Mark functions with DEFUE instead of DEFUN,
19675 if they are used in other modules.
19676 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19677 decls for now-static functions.
19678 * buffer.h (Fdelete_overlay): Remove decl.
19679 * callproc.c (Fgetenv_internal): Mark as internal.
19680 * composite.c (Fremove_list_of_text_properties): Remove decl.

19684 * doc.c (Fdocumntation_property): New forward static decl.
19685 * eval.c (Ffetch_bytecode): New forward static decl.
19686 (Funintern): Remove extern decl; now in .h file where it belongs.
19687 * fileio.c (Fmake_symbolic_link): New forward static decl.
19688 * image.c (Finit_image_library): New forward static decl.
19689 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
19690 * intervals.h (Fprevious_property_change):
19691 (Fremove_list_of_text_properties): Remove decls.
19692 * keyboard.c (Fthis_command_keys): Remove decl.
19693 (Fcommand_execute): New forward static decl.
19694 * keymap.c (Flookup_key): New forward static decl.
19695 (Fcopy_keymap): Now static.
19696 * keymap.h (Flookup_key): Remove decl.
19697 * process.c (Fget_process): New forward static decl.
19698 (Fprocess_datagram_address): Mark as internal.

19709 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
19711 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
19714 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19716 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19717 when at ZV. (Bug#8487)
19719 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19721 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19723 * keyboard.c (parse_tool_bar_item): Likewise.
19724 * sound.c (sound_cleanup, alsa_close): Likewise.
19725 * termcap.c (tgetent): Likewise.
19726 * xfns.c (x_default_font_parameter): Likewise.
19727 * xsettings.c (read_and_apply_settings): Likewise.
19729 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19730 (overrun_check_free): Protoize.
19732 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19734 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19735 since callers should never pass a negative size.
19736 Change the signature to match that of plain 'read' and 'write'; see
19737 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19738 * lisp.h: Update prototypes of emacs_write and emacs_read.
19740 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19742 * xdisp.c (redisplay_window): Don't try to determine the character
19743 position of the scroll margin if the window start point w->startp
19744 is outside the buffer's accessible region. (Bug#8468)
19746 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19748 Fix write-region and its subroutines for buffers > 2GB.
19749 * fileio.c (a_write, e_write): Modify declaration of arguments and
19750 local variables to support buffers larger than 2GB.
19751 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19753 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19754 argument, local variables, and return value.
19756 * lisp.h: Update prototypes of emacs_write and emacs_read.
19758 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19760 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19762 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19764 Fix more problems found by GCC 4.6.0's static checks.
19766 * xdisp.c (vmessage): Use a better test for character truncation.
19768 * charset.c (load_charset_map): <, not <=, for optimization,
19769 and to avoid potential problems with integer overflow.
19770 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19771 * casetab.c (set_identity, shuffle): Likewise.
19772 * editfns.c (Fformat): Likewise.
19773 * syntax.c (skip_chars): Likewise.
19775 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19776 This also lets GCC 4.6.0 generate slightly better loop code.
19778 * callint.c (Fcall_interactively): <, not <=, for optimization.
19779 (Fcall_interactively): Count the number of arguments produced,
19780 not the number of arguments given. This is simpler and lets GCC
19781 4.6.0 generate slightly better code.
19783 * ftfont.c: Distingish more carefully between FcChar8 and char.
19784 The previous code passed unsigned char * to a functions like
19785 strlen and xstrcasecmp that expect char *, which does not
19786 conform to the C standard.
19787 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19788 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19789 char * when the C standard requires it.
19791 * keyboard.c (read_char): Remove unused var.
19793 * eval.c: Port to Windows vsnprintf (Bug#8435).
19794 Include <limits.h>.
19795 (SIZE_MAX): Define if the headers do not.
19796 (verror): Do not give up if vsnprintf returns a negative count.
19797 Instead, grow the buffer. This ports to Windows vsnprintf, which
19798 does not conform to C99. Problem reported by Eli Zaretskii.
19799 Also, simplify the allocation scheme, by avoiding the need for
19800 calling realloc, and removing the ALLOCATED variable.
19802 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19804 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19805 But keep the doprint source code for now, as we might revamp it
19806 and use it again (Bug#8435).
19807 * lisp.h (doprnt): Remove.
19808 * Makefile.in (base_obj): Remove doprnt.o.
19809 * deps.mk (doprnt.o): Remove.
19811 error: Print 32- and 64-bit integers portably (Bug#8435).
19812 Without this change, on typical 64-bit hosts error ("...%d...", N)
19813 was used to print both 32- and 64-bit integers N, which relied on
19814 undefined behavior.
19815 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19816 * lisp.h (error, verror): Mark as printf-like functions.
19817 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19818 Report overflow in size calculations when allocating printf buffer.
19819 Do not truncate output string at its first null byte.
19820 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19821 Truncate the output at a character boundary, since vsnprintf does not
19823 * charset.c (check_iso_charset_parameter): Convert internal
19824 character to string before calling 'error', since %c now has the
19826 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19827 overflow when computing char to be passed to 'error'. Do not
19828 pass Lisp_Object to 'error'; pass the integer instead.
19829 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19830 formatted with plain %d.
19832 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19834 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19836 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19838 * xterm.c (x_catch_errors): Remove duplicate declaration.
19840 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19842 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19844 2011-04-10 Jim Meyering <meyering@redhat.com>
19846 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19847 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19848 return ssize_t not "int", and use size_t as the buffer length.
19849 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19850 * gnutls.h: Update declarations.
19851 * process.c (read_process_output): Use ssize_t, to match.
19852 (send_process): Likewise.
19854 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19856 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19858 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19860 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19861 Use unsigned char, to match FcChar8 type definition.
19863 * xterm.c (handle_one_xevent):
19864 * xmenu.c (create_and_show_popup_menu):
19865 * xselect.c (x_decline_selection_request)
19866 (x_reply_selection_request): Avoid type-punned deref of X events.
19868 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19870 Fix some uses of `int' instead of EMACS_INT.
19871 * search.c (string_match_1, fast_string_match)
19872 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19873 (scan_buffer, find_next_newline_no_quit)
19874 (find_before_next_newline, search_command, Freplace_match)
19875 (Fmatch_data): Make some `int' variables be EMACS_INT.
19877 * xdisp.c (display_count_lines): 3rd argument and return value now
19878 EMACS_INT. All callers changed.
19879 (pint2hrstr): Last argument is now EMACS_INT.
19881 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19882 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19883 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
19884 (decode_coding_utf_16, decode_coding_emacs_mule)
19885 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
19886 (decode_coding_ccl, decode_coding_charset)
19887 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
19888 (decode_coding_iso_2022, decode_coding_emacs_mule)
19889 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
19890 <char_offset, last_offset>: Declare EMACS_INT.

19892 (encode_coding_emacs_mule, encode_invocation_designation)
19893 (encode_designation_at_bol, encode_coding_iso_2022)
19894 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19895 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19897 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19898 (encode_invocation_designation): Last argument P_NCHARS is now
19900 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19901 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19903 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19906 * ccl.c (Fccl_execute_on_string): Declare some variables
19909 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19911 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19913 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19915 * process.c (Fformat_network_address): Doc fix.
19917 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19919 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19921 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19923 * keyboard.c (read_char): Call Lisp function help-form-show,
19924 instead of using internal_with_output_to_temp_buffer.
19925 (Qhelp_form_show): New var.
19926 (syms_of_keyboard): Use DEFSYM macro.
19928 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19932 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19934 * process.c (Flist_processes): Remove to Lisp.
19935 (list_processes_1): Delete.
19937 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19939 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19941 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19943 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19945 Fix more problems found by GCC 4.6.0's static checks.
19947 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19949 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19951 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19953 * xdisp.c (vmessage): Mark as a printf-like function.
19955 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19957 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19959 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19960 printf-like functions.
19961 (tiff_load): Add casts to remove these marks before passing them
19962 to system-supplied API.
19964 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19966 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19967 This avoids several warnings with gcc -Wstrict-overflow.
19968 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19969 directly, rather than having caller test rule sign. This avoids
19970 some unnecessary tests.
19971 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19972 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19973 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19975 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19976 (xfont_open): Avoid unnecessary tests.
19978 * composite.c (composition_gstring_put_cache): Use unsigned integer.

19987 by using the new macro.
19989 * textprop.c (set_text_properties_1): Change while to do-while,
19990 since the condition is always true at first.
19992 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19993 (interval_deletion_adjustment): Return unsigned value.
19996 * process.c (list_processes_1, create_pty, read_process_output):
19997 (exec_sentinel): Remove vars that were set but not used.
19998 (create_pty): Remove unnecessary "volatile"s.

20001 (read_process_output): Simplify nbytes computation if buffered.
20003 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
20005 * syntax.c (scan_words): Remove var that was set but not used.
20006 (update_syntax_table): Use unsigned instead of int.
20008 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

20012 * print.c (print_error_message): Avoid int overflow.
20014 * font.c (font_list_entities): Redo for clarity,
20015 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

20030 (wordify): Omit three unnecessary tests.
20032 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

20035 * casefiddle.c (casify_region): Remove var that is set but not used.
20037 * dired.c (file_name_completion): Remove var that is set but not used.
20039 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20041 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20042 (Finsert_file_contents): Remove unnecessary code checking fd.
20044 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20045 Check for integer overflow on size calculations.
20047 * buffer.c (Fprevious_overlay_change): Remove var that is set
20050 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20051 Remove vars that are set but not used.
20052 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20053 (timer_check_2): Mark vars as initialized.
20055 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20057 * image.c (lookup_image): Remove var that is set but not used.
20058 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20060 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20061 that are set but not used.
20063 * xfns.c (make_invisible_cursor): Don't return garbage
20064 if XCreateBitmapFromData fails (Bug#8410).
20066 * xselect.c (x_get_local_selection, x_handle_property_notify):
20067 Remove vars that are set but not used.
20069 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20070 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20072 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20073 Remove var that is set but not used.
20074 (scroll_bar_windows_size): Now size_t, not int.
20075 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20076 Check for overflow.
20078 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20079 (map_tty_color) [!defined MSDOS]: Likewise.
20081 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20083 * coding.c: Remove vars that are set but not used.
20084 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20085 All callers changed.
20086 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20087 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20088 (decode_coding_charset): Remove vars that are set but not used.
20090 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20091 that is set but not used.
20093 * print.c (print_object): Remove var that is set but not used.
20095 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20096 The gnulib version avoids calling malloc in the usual case,
20097 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20098 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20099 * filelock.c (current_lock_owner): Likewise.
20100 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20101 * sysdep.c: Include allocator.h, careadlinkat.h.
20102 (emacs_no_realloc_allocator): New static constant.
20103 (emacs_readlink): New function.
20104 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20105 ../lib/careadlinkat.h.
20107 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20109 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20110 first non-nil return value).

20126 (get_per_char_metric): Remove parameter `f', unused since
20127 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20129 2011-04-02 Jim Meyering <meyering@redhat.com>
20131 do not dereference NULL upon failed strdup
20132 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20133 (ns_get_family): Likewise.
20135 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20137 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20139 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20141 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20144 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20146 Add lexical binding.
20148 * window.c (Ftemp_output_buffer_show): New fun.
20149 (Fsave_window_excursion):
20150 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20152 * lread.c (lisp_file_lexically_bound_p): New function.
20153 (Fload): Bind Qlexical_binding.
20154 (readevalloop): Remove `evalfun' arg.
20155 Bind Qinternal_interpreter_environment.
20156 (Feval_buffer): Bind Qlexical_binding.
20157 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20159 (syms_of_lread): Declare `lexical-binding'.
20161 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20163 * keyboard.c (eval_dyn): New fun.
20164 (menu_item_eval_property): Use it.
20166 * image.c (parse_image_spec): Use Ffunctionp.
20168 * fns.c (concat, mapcar1): Accept byte-code-functions.
20170 * eval.c (Fsetq): Handle lexical vars.
20171 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20172 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20173 (FletX, Flet): Obey lexical binding.
20174 (Fcommandp): Handle closures.
20175 (Feval): New `lexical' arg.
20176 (eval_sub): New function extracted from Feval. Use it almost
20177 everywhere where Feval was used. Look up vars in lexical env.
20179 (Ffunctionp): Move from subr.el.
20180 (Ffuncall): Handle closures.
20181 (apply_lambda): Remove `eval_flags'.
20182 (funcall_lambda): Handle closures and new byte-code-functions.
20183 (Fspecial_variable_p): New function.
20184 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20185 but without exporting it to Lisp.
20187 * doc.c (Fdocumentation, store_function_docstring):
20188 * data.c (Finteractive_form): Handle closures.
20190 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20193 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20195 (exec_byte_code): New function extracted from Fbyte_code to handle new
20196 calling convention for byte-code-functions. Add new byte-codes.
20198 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20200 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20202 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20204 * xdisp.c (redisplay_internal): Fix prototype.
20206 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20208 * xdisp.c (SCROLL_LIMIT): New macro.
20209 (try_scrolling): Use it when setting scroll_limit.
20210 Limit scrolling to 100 screen lines.
20211 (redisplay_window): Even when falling back on "recentering",
20212 position point in the window according to scroll-conservatively,
20213 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20215 (try_scrolling): When point is above the window, allow searching
20216 as far as scroll_max, or one screenful, to compute vertical
20217 distance from PT to the scroll margin position. This prevents
20218 try_scrolling from unnecessarily failing when
20219 scroll-conservatively is set to a value slightly larger than the
20220 window height. Clean up the case of PT below the margin at bottom
20221 of window: scroll_max can no longer be INT_MAX. When aggressive
20222 scrolling is in use, don't let point enter the opposite scroll
20223 margin as result of the scroll.
20224 (syms_of_xdisp) <scroll-conservatively>: Document the
20225 threshold of 100 lines for never-recentering scrolling.
20227 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20229 * dispextern.h (move_it_by_lines):

20232 (message_log_check_duplicate): Remove parameters `prev_bol' and
20233 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20234 (redisplay_internal): Remove parameter `preserve_echo_area',
20235 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20237 * indent.c (Fvertical_motion):
20238 * window.c (window_scroll_pixel_based, Frecenter):
20239 Don't pass `need_y_p' to `move_it_by_lines'.
20241 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20243 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20244 steal a few bits to be more compact.
20245 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20246 Remove unneeded casts.
20248 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20250 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20252 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20253 binding" message (bug#7967).
20255 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20257 Fix more problems found by GCC 4.6.0's static checks.
20259 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20260 Remove unused local var.
20262 * editfns.c (Fmessage_box): Remove unused local var.
20264 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20265 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20266 Omit unused local vars.
20267 * window.c (shrink_windows): Omit unused local var.
20268 * menu.c (digest_single_submenu): Omit unused local var.
20269 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20270 Omit unused local var.
20272 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20273 Don't assume string length fits in int.
20274 (keyremap_step, read_key_sequence): Use size_t for sizes.
20275 (read_key_sequence): Don't check last_real_key_start redundantly.
20277 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20278 instead of alloca (Bug#8344).
20280 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20281 (Fbacktrace_frame): Don't assume nframes fits in int.
20283 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

20288 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20290 * cm.c (calccost): Turn while-do into do-while, for clarity.
20292 * keyboard.c (syms_of_keyboard): Use the same style as later
20293 in this function when indexing through an array. This also
20294 works around GCC bug 48267.
20296 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20298 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20300 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20301 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20303 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20304 This avoids undefined behavior on integer overflow, and is a bit
20305 more convenient anyway since it is compared to a size_t variable.
20307 Variadic C functions now count arguments with size_t, not int.
20308 This avoids an unnecessary limitation on 64-bit machines, which
20309 caused (substring ...) to crash on large vectors (Bug#8344).

20319 * fns.c (concat): Likewise.
20320 * frame.c (x_set_frame_parameters): Likewise.
20321 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20322 0 if not found, not -1. All callers changed.
20324 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20325 (stack_copy_size): Now size_t, not int.
20326 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20328 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20330 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20331 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20347 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20348 don't set the hook to nil, but remove the offending function instead.
20349 (Qcommand_hook_internal): Remove, unused.
20350 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20351 Vcommand_hook_internal.
20353 * eval.c (enum run_hooks_condition): Remove.
20354 (funcall_nil, funcall_not): New functions.
20355 (run_hook_with_args): Call each function through a `funcall' argument.

20369 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20370 All callers changed.
20372 * w32.c (_wsa_errlist): Use braces for struct initializers.
20374 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

20521 * term.c (Fsuspend_tty, Fresume_tty):
20522 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20523 * window.c (temp_output_buffer_show):
20524 * insdel.c (signal_before_change):
20525 * frame.c (Fhandle_switch_frame):

20530 * callint.c (Fcall_interactively):
20531 * buffer.c (Fkill_all_local_variables):
20532 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20534 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20535 unconditionally since it does the check itself.
20537 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20539 Fix more problems found by GCC 4.5.2's static checks.
20541 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20542 the first time through the loop, since we know p0 < p1 then.
20543 This also avoids a gcc -Wstrict-overflow warning.
20545 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20546 leading to a memory leak, possible in functions like
20547 load_charset_map_from_file that can allocate an unbounded number
20548 of objects (Bug#8318).
20550 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20551 that could (at least in theory) be that large.
20553 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20554 This is less likely to overflow, and avoids undefined behavior if
20555 overflow does occur. All callers changed. Use strtoul to scan
20556 for the unsigned long integer.
20557 (pint2hrstr): Simplify and tune code slightly.
20558 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20568 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20571 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20573 * process.c (Fmake_network_process): Use socklen_t, not int,
20574 where POSIX says socklen_t is required in portable programs.
20575 This fixes a porting bug on hosts like 64-bit HP-UX, where
20576 socklen_t is wider than int (Bug#8277).
20577 (Fmake_network_process, server_accept_connection):
20578 (wait_reading_process_output, read_process_output):
20581 * process.c: Rename or move locals to avoid shadowing.

20591 Make tparam.h and terminfo.c consistent.
20592 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20593 Include tparam.h instead, since it declares them.
20594 * cm.h (PC): Remove extern decl; tparam.h now does this.
20595 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20596 * terminfo.c: Include tparam.h, to check interfaces.
20597 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20598 (tparam): Adjust signature to match interface in tparam.h;
20599 this removes some undefined behavior. Check that outstring and len
20600 are zero, which they always are with Emacs.
20601 * tparam.h (PC, BC, UP): New extern decls.
20603 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20604 (xftfont_open): Rename locals to avoid shadowing.

20621 (find_automatic_composition, composition_adjust_point): Likewise.
20622 (composition_update_it): Mark var as initialized.
20623 (find_automatic_composition): Mark vars as initialized,
20624 with a FIXME (Bug#8290).

20628 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20629 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20630 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20631 to avoid shadowing.
20633 * textprop.c (property_change_between_p): Remove; unused.
20635 * intervals.c (interval_start_pos): Now static.
20637 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20643 Fix pointer signedness.
20644 (alsa_choose_format): Remove unused local var.
20645 (wav_play): Initialize a variable to 0, to prevent undefined
20646 behavior (Bug#8278).
20648 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20650 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20652 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20653 clobbering (Bug#8298).
20654 * sysdep.c (sys_subshell): Likewise.
20655 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20657 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20658 This should get cleaned up, so that child_setup has the
20659 same signature on all platforms.
20661 * callproc.c (call_process_cleanup): Now static.
20662 (relocate_fd): Rename locals to avoid shadowing.
20664 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20666 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20667 not to be necessary, and produces flickering.
20669 2011-03-20 Glenn Morris <rgm@gnu.org>
20671 * config.in: Remove file.
20673 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20675 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20676 are now in src/globals.h.
20677 (syms_of_minibuf): Remove spurious & from previous change.

20703 (sigchld_handler): Now static.
20705 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.

20718 Define only if needed.
20720 * unexelf.c (unexec): Name an expression,
20721 to avoid gcc -Wbad-function-cast warning.
20722 Use a different way to cause a compilation error if anyone uses
20723 n rather than nn, a way that does not involve shadowing.
20724 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20726 * deps.mk (unexalpha.o): Remove; unused.
20728 New file unexec.h, the (simple) interface for unexec (Bug#8267).

20823 (Fmemory_limit): Cast sbrk's returned value to char *.

20849 (RETALLOC_IF): Define only if needed.
20850 (WORDCHAR_P): Likewise. This one is never needed, but is used
20851 only in a comment talking about a compiler bug, so put inside
20852 the #if 0 of that comment.

20880 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20881 New macros, so that the caller can use some names other than
20882 gcpro1, gcpro2, etc.
20883 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20885 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20886 argument, for consistency with GCPRO2_VAR, etc: it is now the
20887 prefix of the variable, not the variable itself. All uses
20889 * dired.c (directory_files_internal, file_name_completion):
20890 Rename locals to avoid shadowing.
20892 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20893 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20894 dired.c's scmp function, had undefined behavior.

20896 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20897 * buffer.h: ... to here, because these macros use current_buffer,
20898 and the new implementation with inline functions needs to have
20899 current_buffer in scope now, rather than later when the macros
20901 (downcase, upcase1): New static inline functions.
20902 (DOWNCASE, UPCASE1): Reimplement using these functions.
20903 This avoids undefined behavior in expressions like
20904 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20905 from race conditions in accessing the global variables

20945 (fix_start_end_in_overlays): Likewise. This function should be
20946 simplified by using pointers-to-pointers, but that's a different

20949 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20950 (report_overlay_modification): Rename locals to avoid shadowing.

20953 Fix pointer signedness issue.
20954 (sys_subshell): Mark local as volatile if checking for lint,
20955 to suppress a gcc -Wclobbered warning that does not seem to be right.
20956 (MAXPATHLEN): Define only if needed.
20958 * process.c (serial_open, serial_configure): Move decls from here ...
20959 * systty.h: ... to here, so that they can be checked.
20961 * fns.c (get_random, seed_random): Move extern decls from here ...

20973 (describe_map_tree):
20974 Rename locals to avoid shadowing.
20976 * keyboard.c: Declare functions static if they are not used elsewhere.

21318 -Wuninitialized does not deduce are never used uninitialized.
21319 (detect_coding_iso_2022): Initialize a local variable that might
21320 be used uninitialized. Leave a FIXME because it's not clear that
21321 this initialization is needed. (Bug#8211)
21322 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
21323 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):

21326 Remove unused macros.
21328 * category.c (hash_get_category_set): Remove unused local var.
21329 (copy_category_table): Now static, since it's not used elsewhere.

21354 Move these decls to tparam.h, and make them agree with what
21355 is actually in tparam.c. The previous trick of using incompatible
21356 decls in different modules does not conform to the C standard.
21357 All callers of tparam changed to use tparam's actual API.
21358 * tparam.c (tparam1, tparam, tgoto):
