43 * insdel.c (move_gap): Remove.
44 (move_gap_both): Add eassert.
45 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

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

74 * buffer.c (buffer_slot_type_mismatch): Remove.
75 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

81 Use Qstringp for default-directory, buffer-file-name,
82 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
83 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
85 * data.c (store_symval_forwarding): Adjust to call the predicate.
87 2013-01-09 Juanma Barranquero <lekktu@gmail.com>

102 (make_gap_1): New function to adjust the gap of any buffer.
103 * coding.c (coding_alloc_by_making_gap): Use it.
104 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
105 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
107 2013-01-08 Juri Linkov <juri@jurta.org>
109 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
110 of (supports :underline (:style wave)). (Bug#13000)

128 trailing dash is properly added.
130 2013-01-05 Eli Zaretskii <eliz@gnu.org>
132 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
133 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
134 digits for buffer positions, before misalignment starts.
135 Display "0" for integer "object" field.
136 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
137 Display the newline glyph more unambiguously.
139 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
141 * nsterm.m (ns_draw_underwave):
142 * w32term.c (w32_draw_underwave):
143 * xterm.c (x_draw_underwave): Make underwave look more triangular
144 and also degrade gracefully for small fonts. (Bug#13000)
146 * nsterm.m (ns_draw_text_decoration):
147 * w32term.c (x_draw_glyph_string):
148 * xterm.c (x_draw_glyph_string): Don't use previous underline
149 thickness and position if previous underline type is underwave.
151 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
153 * fileio.c (Ffile_acl): Undocument return format.
155 2013-01-02 Glenn Morris <rgm@gnu.org>
157 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
159 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
162 * dired.c (file_name_completion):
163 * doc.c (get_doc_string):

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

195 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
196 Check toolbar_is_packed.
197 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
198 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
199 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
201 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
202 (xg_update_menubar): Update title only if
203 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
204 (xg_update_submenu): Skip tearoff only if
205 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
206 (xg_initialize): Initialize xg_detached_menus only if
207 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
209 * xterm.h (struct x_output): Surround handlebox_widget with
210 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
211 toolbar_in_hbox is bool.
213 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
215 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
216 (LIBS_GNUSTEP): Define.
217 (LIBES): Add $(LIBS_GNUSTEP).
218 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
220 2012-12-30 Eli Zaretskii <eliz@gnu.org>
222 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
223 continuation glyph on a TTY with an indication of an empty line.
226 2012-12-29 Eli Zaretskii <eliz@gnu.org>
228 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
229 file's SELinux context or ACLs successfully set, nil otherwise.
231 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
233 * w32proc.c (reader_thread): Avoid passing NULL handles to
234 SetEvent and WaitForSingleObject.
236 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
238 Port EXTERNALLY_VISIBLE to Clang 3.2.
239 * conf_post.h (__has_attribute): New macro.
240 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
242 2012-12-27 Glenn Morris <rgm@gnu.org>
244 * cygw32.c (Fcygwin_convert_file_name_to_windows)

247 2012-12-27 Eli Zaretskii <eliz@gnu.org>
249 * fileio.c (file_name_as_directory, directory_file_name):
250 Accept an additional argument MULTIBYTE to indicate whether the input C
251 came from a multibyte or a unibyte Lisp string; all callers
252 adjusted. Don't assume the input string is always multibyte.
254 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
255 don't ENCODE_FILE them, and return a unibyte string if the input
257 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
258 don't assume the input strings will always be multibyte. If the
259 input strings are multibyte, decode strings obtained from C
262 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
264 * lisp.h (toplevel): Add two notices to the comment about
265 defining a new Lisp data type.
266 * print.c (print_object): If Lisp_Save_Value object's pointer
267 is the address of a memory area containing Lisp_Objects, try
269 * alloc.c (valid_lisp_object_p): Adjust comment.
271 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
273 * keyboard.c (record_asynch_buffer_change): Initialize an event
274 only if it's really needed.
275 * frame.h (enum output_method): Remove output_mac member since
276 it's a leftover from the deleted code.
277 * frame.c (Fframep): Adjust user here ...
278 * terminal.c (Fterminal_live_p): ... and here.
279 * coding.c (Qmac): Now here because it's only used to denote
280 end-of-line encoding type.
281 (syms_of_coding): DEFSYM it.
282 * frame.h (Qmac): Remove duplicated declaration.
284 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
286 * window.c (select_window_1): Now static, since it's used only here.
288 2012-12-25 Eli Zaretskii <eliz@gnu.org>
290 * window.c (window_body_cols): Subtract display margins from the
291 window body width on TTYs as well. See
292 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
293 for the original report.
295 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
297 * xdisp.c (redisplay_window): Remove inner local variable
298 because the outer shadowed one has the same meaning.
299 * xterm.h (struct x_output): Remove toolbar_detached member since it's
301 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
302 (xg_create_tool_bar): Adjust users.
304 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
306 * buffer.h (BUF_COMPACT): New macro to follow the common style.
307 * buffer.c (Fget_buffer_create): Use it to set compact field of
308 struct buffer_text to avoid accessing an uninitialized value
309 when compact_buffer is called for the first time.
310 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
311 (Fset_buffer_modified_p): Use buffer_window_count to check
312 whether the buffer is displayed in some window.
313 * xdisp.c (message_dolog): Likewise.
315 2012-12-23 Eli Zaretskii <eliz@gnu.org>
317 * w32.c (acl_set_file): If setting the file security descriptor
318 fails, and the new DACL is identical to the existing one, silently
319 return success. This fixes problems for users backing up their
320 own files without having the necessary privileges for setting
321 security descriptors.
323 * w32proc.c (reader_thread): Do not index fd_info[] with negative
325 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
326 after WaitForSingleObject returns normally. This expedites reader
327 thread shutdown when delete_child triggers it.
328 (reap_subprocess): More accurate commentary for why we call
329 delete_child only when cp->fd is negative.
331 * w32.c (sys_close): Do not call delete_child on a subprocess
332 whose handle is not yet closed. Instead, set its file descriptor
333 to a negative value, so that reap_subprocess will call
334 delete_child on that subprocess when its SIGCHLD arrives.
335 This avoids closing handles used for communications between sys_select
336 and reader_thread, which doesn't give sys_select a chance to
337 notice that the process exited and invoke the SIGCHLD handler for
340 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
342 * nsfns.m (Fns_do_applescript): Run event loop until script has
343 been executed (Bug#12969).
344 (ns_run_ascript): Chech as_script for nil, set to nil after
347 2012-12-22 Martin Rudalics <rudalics@gmx.at>
349 * window.c (Fselect_window): Reword doc-string (Bug#13248).

353 * w32term.c (w32fullscreen_hook): New function.
354 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
356 2012-12-21 Eli Zaretskii <eliz@gnu.org>
358 * fileio.c (Finsert_file_contents): Doc fix.
360 * w32proc.c (new_child, delete_child, find_child_pid): For a
361 subprocess, consider its slot being in use as long as its process
362 handle (procinfo.hProcess) is not NULL. This avoids reusing the
363 slot when a new process is started immediately after killing
364 another one, without waiting enough time for the first process to
365 be reaped and resources allocated for it be orderly freed.
367 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
369 2012-12-21 Chong Yidong <cyd@gnu.org>
371 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
373 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
375 2012-12-21 Eli Zaretskii <eliz@gnu.org>
377 * w32.c (get_name_and_id): Always pass NULL as the first argument
378 of lookup_account_sid. Avoids crashes with UNC file names that
379 refer to DFS domains, not to specific machine names. (Bug#12621)
380 Remove now unused argument FNAME; all callers changed.
381 (get_file_owner_and_group): Remove now unused argument FNAME; all
384 2012-12-21 Chong Yidong <cyd@gnu.org>
386 * editfns.c (Finsert_char): Since read-char-by-name now signals an
387 error for invalid chars, don't check for a nil return value.
389 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
391 Avoid calls to CHAR_TO_BYTE if byte position is known.
392 * editfns.c (make_buffer_string_both): Use move_gap_both.
393 (Fbuffer_string): Use make_buffer_string_both.
394 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
396 (buf_bytepos_to_charpos): Likewise.
397 (charpos_to_bytepos): Remove.
398 * fileio.c (Finsert_file_contents): Use move_gap_both.
399 * search.c (Freplace_match): Likewise.
400 * process.c (process_send_region): Likewise. Use convenient
401 names for byte positions.
402 * lisp.h (charpos_to_bytepos): Remove prototype.
403 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
404 * insdel.c (move_gap): Likewise.

413 (redisplay_internal): Don't bother selecting the frame to get the
414 proper value of frame-local variables (bug#13225).
416 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
418 * textprop.c (set_text_properties_1): Do not allow NULL interval.
419 Rename 4th argument since it may be buffer or string. Adjust comment.
420 * intervals.c (graft_intervals_info_buffer): Find an interval here.
422 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
424 * coding.c (Fdetect_coding_region): Do not check start and end with
425 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
426 (code_convert_region): Likewise.
428 2012-12-18 Eli Zaretskii <eliz@gnu.org>
430 * w32.c (acl_get_file, acl_set_file): Run the file name through
431 map_w32_filename, and resolve any symlinks in the file name, like
433 (acl_set_file): Call revert_to_self, if any privileges were
436 2012-12-17 Juanma Barranquero <lekktu@gmail.com>

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

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

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

529 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
530 asynchronous subprocess, record the name of the input file name,
532 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
533 delete the file, record it as pending deletion when the subprocess

544 Fix permissions bugs with setgid directories etc. (Bug#13125)
545 * dired.c (Ffile_attributes): Return t as the 9th attribute,

558 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
559 try to get accurate owner and group information from NT file
560 security APIs. This is to make most callers of 'stat' and
561 'lstat', which don't need that information, much faster.
563 * dired.c (Ffile_attributes) [WINDOWSNT]:
564 Set w32_stat_get_owner_group to a non-zero value, to request accurate
565 owner and group information from 'lstat'.

569 * fileio.c (Finsert_file_contents): Don't put tail into head area,
570 as that confuses set-auto-coding, so insist on the head-read
571 returning the full 1024 bytes. Let lseek compute the tail offset;

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

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

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

650 2012-12-11 Eli Zaretskii <eliz@gnu.org>
652 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
653 encoded_file_name, which is what it is.

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

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

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

999 Don't let call-process be a zombie factory (Bug#12980).
1000 Fixing this bug required some cleanup of the signal-handling code.
1001 As a side effect, this change also fixes a longstanding rare race
1002 condition whereby Emacs could mistakenly kill unrelated processes,
1003 and it fixes a bug where a second C-g does not kill a recalcitrant
1004 synchronous process in GNU/Linux and similar platforms.
1005 The patch should also fix the last vestiges of Bug#9488,
1006 a bug which has mostly been fixed on the trunk by other changes.
1007 * callproc.c, process.h (synch_process_alive, synch_process_death)
1008 (synch_process_termsig, sync_process_retcode):
1009 Remove. All uses removed, to simplify analysis and so that
1010 less consing is done inside critical sections.
1011 * callproc.c (call_process_exited): Remove. All uses replaced
1012 with !synch_process_pid.
1013 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1014 These take the role of what used to be in unwind-protect arg.
1016 (block_child_signal, unblock_child_signal):
1017 New functions, to avoid races that could kill innocent-victim processes.
1018 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1019 (call_process_kill): Record killed processes as deleted, so that
1020 zombies do not clutter up the system. Do this inside a critical
1021 section, to avoid a race that would allow the clutter.
1022 (call_process_cleanup): Fix code so that the second C-g works again
1023 on common platforms such as GNU/Linux.
1024 (Fcall_process): Create the child process in a critical section,
1025 to fix a race condition. If creating an asynchronous process,
1026 record it as deleted so that zombies do not clutter up the system.
1027 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1028 light of these changes. Omit unnecessary call to emacs_close
1029 before failure, as the unwind-protect code does that.
1030 * callproc.c (call_process_cleanup):
1031 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1032 * process.c (record_deleted_pid): New function, containing
1033 code refactored out of Fdelete_process.
1034 (Fdelete_process): Use it.
1035 (process_status_retrieved): Remove. All callers changed to use
1036 child_status_change.
1037 (record_child_status_change): Remove, folding its contents into ...
1038 (handle_child_signal): ... this signal handler. Now, this
1039 function is purely a handler for SIGCHLD, and is not called after
1040 a synchronous waitpid returns; the synchronous code is moved to
1041 wait_for_termination. There is no need to worry about reaping
1042 more than one child now.
1043 * sysdep.c (get_child_status, child_status_changed): New functions.
1044 (wait_for_termination): Now takes int * status and bool
1045 interruptible arguments, too. Do not record child status change;
1046 that's now the caller's responsibility. All callers changed.
1047 Reimplement in terms of get_child_status.
1048 (wait_for_termination_1, interruptible_wait_for_termination):
1049 Remove. All callers changed to use wait_for_termination.
1050 * syswait.h: Include <stdbool.h>, for bool.
1051 (record_child_status_change, interruptible_wait_for_termination):
1053 (record_deleted_pid, child_status_changed): New decls.
1054 (wait_for_termination): Adjust to API changes noted above.
1056 * bytecode.c, lisp.h (Qbytecode): Remove.
1057 No longer needed after 2012-11-20 interactive-p changes.
1059 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1061 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1062 the scroll margin, move point outside the margin. (Bug#13055)
1064 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1066 * gtkutil.c (my_log_handler): New function.
1067 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1069 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1071 * lisp.h (modify_region): Rename to...
1072 (modify_region_1): ...new prototype.
1073 * textprop.c (modify_region): Now static. Adjust users.
1074 * insdel.c (modify_region): Rename to...
1075 (modify_region_1): ...new function to work with current buffer.
1076 Adjust comment and users. Use true and false for booleans.
1078 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1080 * alloc.c (free_save_value): New function.
1081 (safe_alloca_unwind): Use it.
1082 * lisp.h (free_save_value): New prototype.
1083 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1085 (save_excursion_restore): Adjust to match saved data structure.
1086 Use free_save_value to offload some work from GC. Drop obsolete
1089 2012-12-03 Chong Yidong <cyd@gnu.org>
1091 * fileio.c (Vauto_save_list_file_name): Doc fix.
1093 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1095 * w32fns.c: Remove prototype of atof.
1096 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1098 (file_dialog_callback): Make it UINT_PTR.
1100 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1103 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1104 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1107 2012-12-03 Glenn Morris <rgm@gnu.org>
1109 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1111 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1113 Fix xpalloc confusion after memory is exhausted.
1114 * alloc.c (xpalloc): Comment fix.
1115 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1116 and signals an error, do not clear charset_table_size, as
1117 charset_table is still valid.
1118 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1120 Use execve to avoid need to munge environ (Bug#13054).
1121 * callproc.c (Fcall_process):
1122 * process.c (create_process):
1123 Don't save and restore environ; no longer needed.
1124 * callproc.c (child_setup):
1125 Use execve, not execvp, to preserve environ.
1127 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1129 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1131 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1133 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1134 display for sliced images (Bug#10500).
1136 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1138 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1140 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1141 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1143 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1145 * xdisp.c (window_outdated): Remove eassert since it hits
1146 some suspicious corner cases (see Bug#13007 and Bug#13012).
1147 (mode_line_update_needed): New function.

1150 (redisplay_internal, unwind_redisplay): Use it.
1151 (redisplay_internal): Move comment about buffer_shared...
1152 (buffer_shared_and_changed): ...near to its real use.
1154 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1156 * callproc.c (Fcall_process): Don't misreport vfork failure.
1158 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1160 * callproc.c (Fcall_process): Fix vfork portability problems.
1161 Do not assume that fd[0], count, filefd, and save_environ survive
1162 vfork. Fix bug whereby wrong errno value could be reported for
1163 pipe failure. Some minor cleanups, too, as follows. Move buf and
1164 bufsize to the context where they're needed. Change new_argv to
1165 be of type char **, as this is more convenient and avoids casts.
1166 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1167 Now local constants, not macros.
1169 2012-11-18 Kenichi Handa <handa@gnu.org>
1171 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1172 for the variable "f".
1174 2012-11-13 Kenichi Handa <handa@gnu.org>
1176 * font.c (font_unparse_xlfd): Exclude special characters from the
1177 generating XLFD name.
1179 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

1219 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1220 between bpos_covered and bpos_max. This fixes cursor display when
1221 several display strings follow each other.
1223 * .gdbinit (pgx): If the glyph's object is a string, display the
1224 pointer to string data, rather than the value of the string object
1225 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1227 * indent.c (Fvertical_motion): If the starting position is covered
1228 by a display string, return to one position before that, to avoid
1229 overshooting it inside move_it_to. (Bug#12930)
1231 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

1250 of a literal "/". (Bug#12955)
1251 (gl-stamp): Invoke fc.exe directly, not through cmd.

1255 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1256 * dired.c: Assume HAVE_DIRENT_H.
1257 (NAMLEN): Remove, replacing with ...
1258 (dirent_namelen): New function. All uses changed. Use the GNU macro
1259 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1260 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1261 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1262 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1264 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1265 * ndir.h: Rename to ../nt/inc/dirent.h.
1266 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1267 Do not include <dirent.h>; no longer needed.
1268 * w32.c: Include <dirent.h> rather than "ndir.h".
1270 2012-11-23 Chong Yidong <cyd@gnu.org>
1272 * xftfont.c (xftfont_open): Remove duplicate assignment.
1274 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1276 * alloc.c (Fgarbage_collect): Unblock input after clearing
1277 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1278 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1279 * msdos.c (IT_frame_up_to_date): Use it here...
1280 * w32term.c (w32_frame_up_to_date): ...here...
1281 * xterm.c (XTframe_up_to_date): ...and here...
1282 * nsterm.m (ns_frame_up_to_date): ...but not here.

1296 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1298 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1299 with Windows system header.

1324 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1326 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1327 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1328 Define for the MSVC compiler.
1330 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1332 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1333 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to

1335 dostounix_filename assumes it gets a unibyte string.
1336 Reported by Michel de Ruiter <michel@sentient.nl>, see

1375 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1376 cygwin_convert_file_name*.

1381 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1383 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1385 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1387 * w32select.c: Include w32common.h before w32term.h, so that
1388 windows.h gets included before w32term.h uses some of its
1389 features, see below.
1391 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1393 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

1400 (ns_select): Return at once if events are held (Bug#12834).
1402 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1404 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1405 Needed following 2012-10-20 change. (Bug#12902)
1407 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1409 * w32proc.c (waitpid): Remove unused label get_result.
1411 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1413 * makefile.w32-in (SYSWAIT_H): New macro.

1421 * emacs.c, term.c (O_RDWR): Remove.
1422 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1423 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1424 * nsterm.m: Assume <fcntl.h> exists.
1425 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1426 (create_pty, Fmake_network_process, server_accept_connection)
1427 (wait_reading_process_output, init_process_emacs):
1429 (wait_reading_process_output): Put in a special case for WINDOWSNT
1430 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1431 It's not clear this is needed, but it's a more-conservative change.
1432 (create_process): Assume FD_CLOEXEC.
1433 (create_process, create_pty): Assume O_NOCTTY.
1434 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1435 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1436 Omit if not DOS_NT, since F_GETFL is not defined there.
1437 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1438 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1440 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1441 lack it, since gnulib guarantees this.
1442 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1444 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1446 * w32.c (faccessat): Pretend that directories have the execute bit
1447 set. Emacs expects that, e.g., in files.el:cd-absolute.
1449 * w32proc.c (create_child): Don't clip the PID of the child
1450 process to fit into an Emacs integer, as this is no longer a
1452 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1453 reaping only the process specified by PID argument, if that is
1454 positive. Use PID instead of dead_child to know which process to
1455 reap. Wait for the child to die only if WNOHANG is not in
1457 (sys_select): Don't set dead_child.
1459 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1460 as it is no longer needed.
1462 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1464 (record_child_status_change): Remove the setting of
1465 record_at_most_one_child for the !WNOHANG case.
1467 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1469 Fix problems in ns port found by static checking.
1470 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1471 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1472 not to process group.
1473 (ns_select): Use emacs_write, not write, as that's more robust
1474 in the presence of signals.
1475 (fd_handler:): Check for read errors.
1477 2012-11-16 Glenn Morris <rgm@gnu.org>
1479 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1481 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1483 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1485 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1487 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1488 use the same value of thread handle.
1489 (start_timer_thread): If the timer thread exited (due to error),
1490 clean up by closing the two handles it used. Duplicate the caller
1491 thread's handle here, so it gets duplicated only once, when
1492 launching the timer thread. Set priority of the timer thread, not
1494 (getitimer): Don't duplicate the caller thread's handle here.
1497 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1499 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1502 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1504 Remove no-longer-used pty_max_bytes variable.
1505 * process.c (pty_max_bytes): Remove; unused.
1506 (send_process): Do not set it.
1508 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1510 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1511 Update dependencies.
1513 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1515 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1516 This follows up on the 2012-09-29 patch that removed indirection
1517 for the 'function' field. Reported by Sergey Vinokurov in
1518 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1520 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1522 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1523 different name, as the MS runtime does not have such a function,
1524 and probably never will.) All callers changed. Ignore DIRFD
1525 value if PATH is an absolute file name, to match Posix spec
1526 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1529 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1531 * xdisp.c (echo_area_display, redisplay_internal):
1532 Omit redundant check whether frame_garbaged is set.
1534 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1536 Use faccessat, not access, when checking file permissions (Bug#12632).
1537 This fixes a bug that has been present in Emacs since its creation.
1538 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1539 which must set some sort of record. (Torek's bug report was against
1540 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1541 same common flaw.) See Torek's Usenet posting
1542 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1543 Posted: Fri Apr 8 14:18:56 1983.
1544 * Makefile.in (LIB_EACCESS): New macro.
1546 * callproc.c (init_callproc):
1547 * charset.c (init_charset):
1548 * fileio.c (check_existing, check_executable, check_writable)
1550 * lread.c (openp, load_path_check):
1551 * process.c (allocate_pty):
1553 Use effective UID when checking permissions, not real UID.
1554 * callproc.c (init_callproc):
1555 * charset.c (init_charset):
1556 * lread.c (load_path_check, init_lread):
1557 Test whether directories are accessible, not merely whether they exist.
1558 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1559 * fileio.c (check_existing, check_executable, check_writable)
1561 Use symbolic names instead of integers for the flags, as they're
1563 (check_writable): New arg AMODE. All uses changed.
1564 Set errno on failure.
1565 (Ffile_readable_p): Use faccessat, not stat + open + close.
1566 (Ffile_writable_p): No need to call check_existing + check_writable.
1567 Just call check_writable and then look at errno. This saves a syscall.
1568 dir should never be nil; replace an unnecessary runtime check
1569 with an eassert. When checking the parent directory of a nonexistent
1570 file, check that the directory is searchable as well as writable, as
1571 we can't create files in unsearchable directories.
1572 (file_directory_p): New function, which uses 'stat' on most platforms
1573 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1574 (Ffile_directory_p, Fset_file_times): Use it.
1575 (file_accessible_directory_p): New function, which uses a single
1576 syscall for efficiency.
1577 (Ffile_accessible_directory_p): Use it.
1578 * xrdb.c (file_p): Use file_directory_p.
1579 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1580 * lread.c (openp): When opening a file, use fstat rather than
1581 stat, as that avoids a permissions race. When not opening a file,
1582 use file_directory_p rather than stat.
1583 (dir_warning): First arg is now a usage string, not a format.
1584 Use errno. All uses changed.
1585 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1586 that merely introduced a race.
1587 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1588 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1589 and similarly for the other O_* flags.
1590 * w32.c (sys_faccessat): Rename from sys_access and switch to
1591 faccessat's API. All uses changed.
1592 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1593 (magic_db): Rename from magic_file_p.
1594 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1595 char *, so that we don't have to test for file existence
1596 separately from opening the file for reading. This removes a race
1597 fixes a permission-checking problem, and simplifies the code.
1599 (file_p): Remove; no longer needed.
1601 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1603 Omit glyphs initialization at startup.
1604 * dispnew.c (glyphs_initialized_initially_p): Remove.
1605 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1606 (Fredraw_frame): Move actual code from here...
1607 (redraw_frame): ...to here. Add eassert. Adjust comment.
1608 (Fredraw_display): Use redraw_frame.
1609 * xdisp.c (clear_garbaged_frames): Likewise.
1611 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1613 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1614 passed to pint2str and pint2hrstr to be at most the size of the
1615 frame's decode_mode_spec_buffer. This avoids crashes with very
1616 large values of FIELD_WIDTH argument to decode_mode_spec.
1619 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1621 Fix a race with verify-visited-file-modtime (Bug#12863).
1622 Since at least 1991 Emacs has ignored an mtime difference of no
1623 more than one second, but my guess is that this was to work around
1624 file system bugs that were fixed long ago. Since the race is
1625 causing problems now, let's remove that code.
1626 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1627 whose time stamp is off by no more than a second. Insist that the
1628 file time stamps match exactly.
1630 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1632 * frame.h (struct frame): Convert external_tool_bar member to
1633 1-bit unsigned bitfield.
1634 * termhooks.h (struct terminal): Remove mouse_moved member since
1635 all users are long dead. Adjust comment on mouse_position_hook.
1637 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1639 Simplify by using FOR_EACH_FRAME here and there.
1640 * frame.c (next_frame, prev_frame, other_visible_frames)
1641 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1642 * w32term.c (x_window_to_scroll_bar): Likewise.
1643 * window.c (window_list): Likewise.
1644 * xdisp.c (x_consider_frame_title): Likewise.
1645 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1646 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1647 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1648 * xmenu.c (menubar_id_to_frame): Likewise.
1649 * xselect.c (frame_for_x_selection): Likewise.
1650 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1651 (x_window_to_menu_bar): Likewise.
1652 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1654 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1656 * data.c (Qdefalias_fset_function): Now static.
1658 Another tweak to vectorlike_header change.
1659 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1660 Remove, and replace all uses with ...
1661 (next_in_free_list, set_next_in_free_list):
1662 New functions, which respect C's aliasing rules better.
1664 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1666 * window.c (list4i): Rename from 'quad'. All uses changed.
1667 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1669 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1671 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1672 warning about mixing declarations and code in ISO C90.
1674 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1676 * window.c (Fsplit_window_internal): Set combination limit of
1677 new parent window to t iff Vwindow_combination_limit is t;
1678 fixing a regression introduced with the change from 2012-09-22.
1679 (Fset_window_combination_limit): Fix doc-string.
1681 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1683 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1684 amount when the scroll margins are too large. When scrolling
1685 backwards in the buffer, give up if cannot reach point or the
1686 scroll margin within a reasonable number of screen lines.
1687 Fixes point position in window under scroll-up/down-aggressively when
1688 point is positioned many lines beyond the window top/bottom.
1691 * ralloc.c (relinquish): If real_morecore fails to return memory
1692 to the system, don't crash; instead, leave the last heap
1693 unchanged and return. (Bug#12774)
1695 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1697 * lisp.h (AUTOLOADP): New macro.
1698 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1699 * data.c (Ffset): Remove special ad-advice-info handling.
1700 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1702 (Finteractive_form): Simplify.
1703 (Fquo): Don't insist on having at least 2 arguments.
1704 (Qdefalias_fset_function): New var.
1706 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1708 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1710 * nsfont.m (Qcondensed, Qexpanded): New variables.
1711 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1712 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1714 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1716 Fix recently introduced crash on MS-Windows (Bug#12839).
1717 * w32term.h (struct scroll_bar): Use convenient header.
1718 (SCROLL_BAR_VEC_SIZE): Remove.
1719 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1721 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1723 Tweak last vectorlike_header change.
1724 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1725 vectorlike object on the free list. This is introduced to avoid
1726 some (but not all) pointer casting and aliasing problems, see
1727 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1728 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1730 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1732 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1734 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1735 been removed, so remove them here also.
1737 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1739 * doc.c (Fdocumentation): Handle new property
1740 dynamic-docstring-function to replace the old ad-advice-info.
1742 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1744 * fns.c (Qeql, hashtest_eq): Now static.
1746 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1748 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1749 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1750 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
1751 * buffer.c (compare_overlays): Use XLI rather than XHASH.
1753 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1755 Use same hash function for hashfn_profiler as for hash_string etc.
1756 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1757 * lisp.h (sxhash_combine): New inline function, with the contents
1758 of the old SXHASH_COMBINE.
1759 * profiler.c (hashfn_profiler): Use it, instead of having a
1760 special hash function containing a comparison that always yields 1.
1762 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1764 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1765 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1766 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1769 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1771 * image.c (xpm_make_color_table_h): Fix compiler error because
1772 make_hash_table changed.
1774 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1776 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1778 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1780 Use ad-hoc comparison function for the profiler's hash-tables.
1781 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1782 (make_log): Use them.
1783 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1784 call Fequal any more.
1785 (Ffunction_equal): New function.
1786 (cmpfn_profiler, hashfn_profiler): New functions.
1787 (syms_of_profiler): Initialize them.
1788 * lisp.h (struct hash_table_test): New struct.

1793 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1794 (hash_lookup, hash_remove_from_table): Move assertion checking of
1795 hashfn result here. Check hash-equality before calling cmpfn.
1796 (Fmake_hash_table): Adjust call to make_hash_table.
1797 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
1798 (syms_of_fns): Initialize them.

1802 * print.c (print_object): Adjust to new hash-table struct.
1803 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
1805 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1807 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1808 value of w32-scroll-lock-modifier is neither nil nor one of the
1809 known key modifiers. (Bug#12806)
1811 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1813 Shrink struct vectorlike_header to the only size field.
1814 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1816 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1817 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1818 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1819 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1820 information from the vector header. Adjust comment.
1821 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
1822 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
1824 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
1825 (struct vectorlike_header): Remove next member. Adjust comment.

1828 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
1829 (sweep_string, lisp_malloc): Remove useless prototypes.
1830 (enum mem_type): Adjust comment.
1831 (NEXT_IN_FREE_LIST): New macro.
1832 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1833 (Fmake_bool_vector): Likewise.
1834 (struct large_vector): New type to represent allocation unit for
1835 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1836 (large_vectors): Change type to struct large_vector.
1837 (allocate_vector_from_block): Simplify.
1838 (PSEUDOVECTOR_NBYTES): Replace with...
1839 (vector_nbytes): ...new function. Adjust users.
1840 (sweep_vectors): Adjust processing of large vectors.
1841 (allocate_vectorlike): Likewise.
1842 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1843 Add easserts. Adjust XSETPVECTYPESIZE usage.
1844 (allocate_buffer): Use BUFFER_PVEC_INIT.
1845 (live_vector_p): Adjust to match large vector.
1846 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1847 * buffer.h (struct buffer): Add next member.
1848 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1850 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1851 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1852 (copy_hash_table): Adjust to match vector header change.
1853 * lread.c (defsubr): Use XSETPVECTYPE.
1854 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
1855 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
1856 (xvecsize): New command.
1858 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1860 * keyboard.c (event_to_kboard): Do not dereference
1861 frame_or_window field of SELECTION_REQUEST_EVENT
1862 and SELECTION_CLEAR_EVENT events (Bug#12814).
1863 * xterm.h (struct selection_input_event): Adjust comment.
1865 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1867 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1868 such as Scroll Lock, if the respective keys are treated as
1869 function keys, not as modifiers. This avoids destroying non-ASCII
1870 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1872 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1874 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1876 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1878 Restore some duplicate definitions (Bug#12814).
1879 This undoes part of the 2012-11-03 changes. Some people build
1880 with plain -g rather than with -g3, and they need the duplicate
1881 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1882 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1883 Define as macros, as well as as enums or as constants.
1885 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1887 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1888 to keypad keys (Bug#12816).
1890 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1892 Minor adjustments of recently-changed frame functions.
1893 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1894 known to be a frame (we're in the FRAMEP branch).
1895 * lisp.h (Qframep): Remove decl. frame.h declares this.
1896 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1897 since they're meant for Lisp fixnum values.
1899 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1901 * window.c (Fwindow_combination_limit): Revert to the only
1902 required argument and adjust docstring as suggested in
1903 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1904 by Martin Rudalics <rudalics@gmx.at>.
1906 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1908 Widely used frame validity and checking functions.
1909 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1910 * frame.c (decode_live_frame, decode_any_frame): New functions.
1911 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1912 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1913 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

1920 (frame_buffer_list, frame_buffer_predicate): Remove.
1921 * lisp.h (frame_buffer_predicate): Remove prototype.
1922 * buffer.c (Fother_buffer): Use decode_any_frame.
1923 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1924 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1925 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1926 (Fclose_font, Ffont_info): Use decode_live_frame.
1927 * fontset.c (check_fontset_name): Likewise.
1928 * terminal.c (Fframe_terminal): Likewise.
1929 * w32fns.c (check_x_frame): Likewise.
1930 * window.c (Fminibuffer_window, Fwindow_at)
1931 (Fcurrent_window_configuration): Likewise.

1933 Likewise. Allow zero number of arguments. Adjust docstring.
1934 * dispnew.c (Fredraw_frame): Likewise.
1935 * xfaces.c (frame_or_selected_frame): Remove.
1936 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1937 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1938 (Fframe_face_alist): Use decode_live_frame.
1939 * xfns.c (check_x_frame): Likewise.
1941 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1943 * window.c (quad): New function.
1944 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1945 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1946 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1947 (Fwindow_line_height): Use it.
1948 (Fwindow_fringes): Use list3.
1949 (Fwindow_scroll_bars): Use list4.
1950 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1951 (Fwindow_combination_limit): Allow zero number of arguments.
1953 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1955 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1957 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1958 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1959 file descriptor 2 for standard error. (Bug#12805)
1961 2012-11-05 Chong Yidong <cyd@gnu.org>
1963 * process.c (wait_reading_process_output): Revert previous change.
1965 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1967 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1968 This removes code that has been obsolete since around 1990.
1969 * callproc.c (Fcall_process):
1971 * process.c (create_process):
1972 * term.c (dissociate_if_controlling_tty):
1973 Assume setsid exists.
1974 * callproc.c (child_setup): Assume setpgid exists and behaves as
1975 per POSIX.1-1988 or later.
1976 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1977 * emacs.c (shut_down_emacs):
1978 * sysdep.c (sys_suspend, init_foreground_group):
1979 Assume getpgrp behaves as per POSIX.1-1998 or later.
1980 * msdos.c (setpgrp): Remove.
1981 (tcgetpgrp, setpgid, setsid): New functions.
1982 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1983 * term.c (no_controlling_tty): Remove; unused.
1984 * w32proc.c (setpgrp): Remove.
1985 (setsid, tcgetpgrp): New functions.
1987 Simplify by assuming __fpending.
1988 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1989 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1990 Do not assume that __fpending's result fits in int.
1992 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1994 Remove EMACS_OUTQSIZE+sleep hack.
1995 * dispnew.c (update_frame_1): Remove hack for terminals slower
1996 than 2400 bps, which throttled Emacs by having it sleep.
1997 This code hasn't worked since at least 2007, when the multi-tty stuff
1998 was added, and anyway those old terminals are long dead.
1999 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2000 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2002 Fix data-loss with --version (Bug#9574).
2003 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2004 as we can't assume that emacs_strerror is initialized, and strerror
2005 is good enough here.
2006 (main): Invoke atexit earlier, to catch earlier instances of
2007 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2009 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2011 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2012 (keyDown): Remap keypad keys to X11 virtual key codes.
2014 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2016 Fix data-loss with --batch (Bug#9574).
2017 * emacs.c: Include <close-stream.h>.
2018 (close_output_streams): New function.
2019 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2020 and handles errors appropriately.
2021 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2024 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2025 The symptom is a diagnostic "GLib-WARNING **: In call to
2026 g_spawn_sync(), exit status of a child process was requested but
2027 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2028 waitpid(), so exit status can't be returned." The diagnostic
2029 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2030 The real bug is a race condition between Emacs and glib: Emacs
2031 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2032 so that glib can't find it. Work around the bug by invoking
2033 waitpid only on subprocesses that Emacs itself creates.
2034 * process.c (create_process, record_child_status_change):
2035 Don't use special value -1 in pid field, as the caller now must
2036 know the pid rather than having the callee infer it.
2037 The inference was sometimes incorrect anyway, due to another race.
2038 (create_process): Set new 'alive' member if child is created.
2039 (process_status_retrieved): New function.
2040 (record_child_status_change): Use it.
2041 Accept negative 1st argument, which means to wait for the
2042 processes that Emacs already knows about. Move special-case code
2043 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2044 processes that have already been waited for, by testing and
2045 clearing new 'alive' member.
2046 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2047 now does this internally.
2048 (handle_child_signal): Let record_child_status_change do all
2049 the work, since we do not want to reap all exited child processes,
2050 only the child processes that Emacs itself created.
2051 * process.h (Lisp_Process): New boolean member 'alive'.
2053 Omit duplicate definitions no longer needed with gcc -g3.
2054 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2055 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2056 Define only as macros. There's no longer any need to also define
2057 these symbols as enums or as constants, since we now assume
2058 gcc -g3 when debugging.
2060 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2062 * lisp.mk: Adjust comments to the fact that term/internal is now
2063 loaded from loadup.el.
2065 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2066 (msdos_fatal_signal): New function.
2067 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2070 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2071 for GCC versions before 4.
2072 (emacs_raise): Define to call msdos_fatal_signal.
2074 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2075 iterator when starting in the middle of a display or overlay
2078 2012-11-03 Chong Yidong <cyd@gnu.org>
2080 * process.c (wait_reading_process_output): Clean up the last
2083 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2085 * process.c (wait_reading_process_output): Avoid a race condition
2086 with SIGIO delivery (Bug#11536).
2088 2012-11-03 Chong Yidong <cyd@gnu.org>
2090 * buffer.c (cursor_type): Untabify docstring.
2092 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2094 * frame.h (struct frame): Drop can_have_scroll_bars member
2095 which is meaningless for a long time. Adjust comments.
2096 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2097 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2099 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2101 * window.c (decode_next_window_args): Update window arg after
2102 calling decode_live_window and so fix crash reported at
2103 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2104 by Juanma Barranquero <lekktu@gmail.com>.
2105 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2106 * font.c (Ffont_at): Likewise.
2108 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2110 * widget.c (resize_cb): New function.
2111 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2112 (EmacsFrameResize): Check if all is up to date before changing frame
2115 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2117 Implement backtrace output for fatal errors on MS-Windows.
2118 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2119 (BACKTRACE_LIMIT_MAX): New macro.
2120 (w32_backtrace): New function.
2121 (emacs_abort): Use w32_backtrace when the user chooses not to
2122 attach a debugger. Update the text of the abort dialog.
2124 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2126 Window-related stuff cleanup here and there.
2127 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2128 Use decode_any_window.
2129 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2130 * xdisp.c (Fformat_mode_line): Likewise.
2131 * font.c (Ffont_at): Use decode_live_window.
2132 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2133 * window.c (decode_next_window_args): Likewise.
2134 (decode_any_window): Remove static.
2135 * window.h (decode_any_window): Add prototype.
2136 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2137 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2140 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2142 Remove pad from struct input_event.
2143 * termhooks.h (struct input_event): Remove padding field.
2145 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2146 member is never cons for a long time. Adjust comment.
2147 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2148 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2149 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2150 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2152 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2154 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2156 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2158 Fix crash when using Emacs as commit editor for git (Bug#12697).
2159 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2160 and it is configured in conf_post.h.
2161 (Fcall_process): Don't invoke both setsid and setpgid; the former
2162 is enough, if it exists.
2163 * callproc.c (Fcall_process, child_setup):
2164 * process.c (create_process): Use setpgid.
2165 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2167 * dispnew.c (init_display): Initialize the foreground group
2168 if we are running a tty display.
2169 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2170 * lisp.h (init_foreground_group): New decl.
2171 * sysdep.c (inherited_pgroup): New static var.
2172 (init_foreground_group, tcsetpgrp_without_stopping)
2173 (narrow_foreground_group, widen_foreground_group): New functions.
2174 (init_sys_modes): Narrow foreground group.
2175 (reset_sys_modes): Widen foreground group.
2177 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2179 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2181 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2183 * minibuf.c (read_minibuf): Restore current buffer since
2184 choose_minibuf_frame calling Fset_frame_selected_window may
2185 change it (Bug#12766).
2187 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2189 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2191 2012-10-30 Kenichi Handa <handa@gnu.org>
2193 * font.c (Ffont_at): If WINDOW is specified and it is not
2194 displaying the current buffer, signal an error.
2196 2012-10-29 Daniel Colascione <dancol@dancol.org>
2198 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2199 In preparation for fixing bug#12739, move these functions from
2202 * coding.h, coding.c: ... to here, and compile them only when
2203 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2204 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2206 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2208 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2209 (timer_loop, getitimer, setitimer): Use it instead of
2210 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2212 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2215 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2217 * nsterm.m (NO_APPDEFINED_DATA): New define.
2218 (last_appdefined_event_data): New variable
2219 (last_appdefined_event): Remove.
2220 (ns_select): Initialize t from last_appdefined_event_data instead
2221 of [last_appdefined_event data1].
2222 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2223 remove last_appdefined_event (Bug#12698).
2225 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2227 * frame.c (x_set_font): Catch internal error.
2229 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2231 Avoid overflow in w32 implementation of interval timers.
2232 When possible, for ITIMER_PROF count only times the main thread
2234 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2235 'volatile ULONGLONG' types. All the other data which was
2236 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2237 (GetThreadTimes_Proc): New typedef.
2238 (w32_get_timer_time): New function, returns a suitable time value
2240 (timer_loop): Enter critical section when accessing ULONGLONG
2241 values of the itimer_data struct, as these accesses are no longer
2242 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2243 Remove unused variable.
2244 (init_timers): Initialize s_pfn_Get_Thread_Times.
2245 (start_timer_thread): Don't assign itimer->caller_thread here.
2246 (getitimer): Assign itimer->caller_thread here.
2247 (setitimer): Always call getitimer to get the value of ticks_now.
2248 (sys_spawnve): Avoid compiler warning about format mismatch.
2250 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2252 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2253 mouse movement events if the menu bar is active. This avoids
2254 producing a busy "hour-glass" cursor by Windows if the mouse
2255 pointer is positioned over a tooltip shown for some menu item.
2257 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2259 Don't assume process IDs fit in int.
2260 * emacs.c (shut_down_emacs) [!DOS_NT]:
2261 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2262 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2263 Use pid_t, not int, to store process IDs, as 'int'
2264 is not wide enough on a few platforms (e.g., AIX and IRIX).
2266 2012-10-23 Kenichi Handa <handa@gnu.org>
2268 The following change is to make face-font-rescale-alist work
2269 correctly for non-ASCII fonts.
2271 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2272 (font_open_for_lface): Handle Vface_font_rescale_alist.
2274 2012-10-23 Chong Yidong <cyd@gnu.org>
2276 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2278 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2280 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2282 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2284 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2287 2012-10-21 Glenn Morris <rgm@gnu.org>
2289 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2291 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2293 Port to OpenBSD 5.1.
2294 * frame.c (Fmouse_position, Fmouse_pixel_position):
2295 * xdisp.c (produce_stretch_glyph):
2296 Declare local vars only when they're needed.
2297 This is clearer and avoids a warning on OpenBSD about unused vars.
2298 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2299 This is safer, and avoids OpenBSD warnings about unused vars.
2300 * keyboard.c (record_menu_key): Remove unnecessary decl.
2301 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2302 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2303 as our definition clashes with OpenBSD's.
2304 * xfaces.c (load_face_colors, check_lface_attrs)
2305 (get_lface_attributes_no_remap, get_lface_attributes)
2306 (lface_fully_specified_p, x_supports_face_attributes_p)
2307 (tty_supports_face_attributes_p, face_fontset, realize_face)
2308 (realize_x_face, realize_tty_face):
2309 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2310 merely Lisp_Object *. This is more informative and avoids
2311 a warning on OpenBSD about accessing beyond an object's size.
2313 2012-10-20 Chong Yidong <cyd@gnu.org>
2315 * lread.c (Fload): Doc fix (Bug#12592).
2317 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2319 * font.c (Ffont_at): Fix previous change.
2321 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2323 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2324 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2327 * alloc.c (NSTATICS): Decrease to 0x800.
2329 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
2331 * fns.c (Fnreverse): Include the problem element when signaling an
2334 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2336 * nsterm.m (ns_select): Check writefds before call to
2337 FD_ISSET (Bug#12668).
2339 2012-10-18 Daniel Colascione <dancol@dancol.org>
2341 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2342 (staticpro): If we run out of staticpro slots, die with an
2343 informative error instead of just calling emacs_abort.

2602 since unsigned is guaranteed to have that behavior and signed is not.
2603 (read_char): Use ptrdiff_t for string length.
2604 (get_input_pending): Remove first argument, since it was always
2605 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2606 and behave as if it had that value. Return new value of
2607 input_pending. All callers changed.
2608 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2609 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

2655 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2656 'is_tooltip_frame', to avoid confusion with its global namesake.
2658 2012-10-08 Daniel Colascione <dancol@dancol.org>
2660 * xdisp.c (start_hourglass): Call w32_note_current_window when
2661 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2662 build that caused Emacs to display the hourglass cursor forever.
2664 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2665 which is broken under remote desktop, calculate the number of
2666 colors available for a display based on the display's number of
2667 planes and number of bits per pixel per plane. (bug#10397).
2669 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2671 * nsfont.m (Vfonts_in_cache): New variable.

2706 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2707 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close

2732 Use `report_file_error' instead of `error' in order to better
2733 inform users of what went wrong. Increase NTGUI_UNICODE file
2734 dialog box file name length to 32k, the maximum allowed by the NT
2737 * w32common.h: New file.

2744 * unexw32.c, unexcw.c: Include w32common.h.
2746 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2747 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2748 to call syms_of_w32select.
2750 * cygw32.h: Remove obsolete EXFUN declarations.

2769 2012-10-08 Daniel Colascione <dancol@dancol.org>
2771 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2772 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,

2776 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2777 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2778 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2779 now a supported configuration.
2781 * Makefile.in: consolidate image variables into LIBIMAGE; add
2782 W32_OBJ and W32_LIBS. Compile new files.
2785 (_DebPrint) declare tracing facility for W32 debugging. We need
2786 to unify tracing later.
2788 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2789 unconditional use of W32 Unicode functions. Cygwin runs only on
2790 100% Unicode operating systems.
2792 * cygw32.c: New file. Define Cygwin-specific facilities.
2793 (Fcygwin_convert_path_to_windows)
2794 (Fcygwin_convert_path_from_windows): New user functions for
2795 accessing Cygwin path-munging routines.
2797 * cygw32.h: New file.
2798 (WCSDATA, to_unicode, from_unicode): Define facilities for storing

2802 (w32_strerror): Just what it says on the tin.
2804 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2805 also run for Cygwin; both systems have the same problem with using
2806 GUI facilities in a forked child. Also call syms_of_cygw32,
2807 syms_of_w32select in correct places.
2809 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2810 needs fork-then-exec for daemon launching.
2812 * font.h: Include frame.h.
2814 * image.c: Use the image library cache machinery only when we're
2815 compiling for native WINDOWSNT; Cygwin can use shared libraries
2816 like any other Unixlike system.
2818 * keyboard.c: Clarify a comment regarding the input loop.
2820 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2821 functions directly instead of trying to detect at runtime that our
2822 host operating system supports them. We make this change for two
2823 reasons: Cygwin lacks support for the multibyte character
2824 conversion functions used by the legacy menu code, and Cygwin
2825 never needs to rely on non-Unicode APIs.
2827 * unexw32.c (hinst): Declare extern.
2829 * w32.c: Change header order;
2830 (w32_strerror): Move to w32fns.c because we need it for
2831 non-WINDOWSNT builds.
2833 * w32.h: Add #error macro to make sure we don't include w32.h for
2834 Cygwin builds. Remove w32select declarations.
2836 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2837 w32fns.c. w32console.c is WINDOWSNT-only.
2839 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2840 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2842 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2843 (w32_major_version, w32_minor_version, w32_build_number)
2844 (os_subtype, sound_type): Define here
2845 (w32_defined_color): Make color parameter const for consistency
2846 with other _defined_color functions.
2847 (w32_createwindow): Unconditionally call w32_init_class instead of
2848 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2849 through the code is complex and unnecessary because class
2850 registration is practically free.
2851 (w32_name_of_message): New EMACSDEBUG-only function.
2852 (Fset_message_beep): Move here
2853 (Fx_open_connection): Require that the display name for Windows be
2854 "w32" for consistency, emacsclient disambiguation, and maybe, one
2855 day, multi-window-system support.
2856 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2857 Cygwin files for W32 GUI facilities, since these clearly don't
2858 expect Cygwin names.
2859 (_DebPrint): Define.
2860 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2861 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2862 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2863 (w32_last_error): Remove.
2865 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2867 * w32heap.c (syspage_mask): Declare here.
2868 (cache_system_info): Remove.
2870 * w32inevt.c (faked_key): Define globally, not statically.
2871 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2872 (w32_console_toggle_lock_key): Move to w32fns.c.
2874 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2876 * w32proc.c (_DebPrint): Move to w32fns.c.
2877 * w32select.c: Include string.h, stdio.h for Cygwin.
2878 * w32select.h: New File.
2880 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2882 (w32_message_fd): New variable. Under Cygwin, holds the file
2883 descriptor the system used to tell us about pending thread
2886 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2887 that prevented compilation under non-WINDOWSNT systems.
2889 (w32_initialize): Open /dev/windows and assign it to
2890 w32_message_fd. Provide w32 feature.
2892 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2893 (WM_EMACS_INPUT_READY): add.
2894 (prepend_msg, w32_message_fd): Declare globally.
2897 (keyboard_handle): Use only when WINDOWSNT.
2898 (notify_msg_ready): New function. Posts a message to the main
2899 thread's message queue under CYGWIN, which wakes up the main
2900 thread from select(2) by making the /dev/windows file descriptor
2901 ready. Under WINDOWSNT, it sets an event the same way the old
2904 (post, prepend_msg): Actually call notify_msg_ready instead of
2905 setting the input event directly.
2907 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2909 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2910 but it still has blocs in it, don't return it to the system,
2911 instead of aborting. (Bug#12402)
2913 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2915 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2917 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2918 MAC_OS_X_VERSION_10_6.
2919 (syms_of_nsterm): Remove comment about Panther and above for
2921 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2922 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2923 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2925 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2926 MAC_OS_X_VERSION_10_4.
2928 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2929 MAC_OS_X_VERSION_10_2.
2931 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2933 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2934 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2936 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2937 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2938 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2939 Remove ns_in_resize check.
2940 (ns_clear_frame_area): Remove resize handle code.
2942 * nsfns.m (ns_in_resize): Remove.
2943 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2944 Remove ns_in_resize check.
2946 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2948 Improve sys_siglist detection.
2949 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2950 defined as a macro, as is done in Solaris.
2951 (sys_siglist_entries): New macro.
2952 (save_strsignal): Use it.
2953 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2954 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2956 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2958 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2959 fullscreen/Fullscreen.
2961 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2962 tobar_height is new.
2964 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2965 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2966 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2967 (windowDidResize:): Check for correct window if old style fullscreen.
2968 Capitalize word in comment. Remove incorrect comment.
2969 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2970 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2971 error in drawing background.
2972 (toggleFullScreen:): Remove comment. Rearrange calls.
2973 Set toolbar values to zero, save old height in tobar_height.
2974 Restore tool bar height when leaving fullscreen.
2975 (canBecomeMainWindow): New function.
2977 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2979 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2981 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2983 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2985 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2986 that time stamps of directories could also be changed.
2987 Don't request the too broad GENERIC_WRITE, only the more restrictive
2988 FILE_WRITE_ATTRIBUTES access rights.
2990 * fileio.c (Fset_file_times): Special-case ignoring errors for
2991 directories only on MSDOS, not on MS-Windows.
2993 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2995 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2997 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2999 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3000 see whether CreateFile failed.
3002 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3004 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3005 to avoid similar races.
3006 * keyboard.c (pending_signals): Now bool, not int.
3008 Port timers to OpenBSD, plus check for timer failures.
3009 OpenBSD problem reported by Han Boetes.
3010 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3012 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3013 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3014 like OpenBSD, which has timer_settime but does not declare it.
3015 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3016 whether to use itimerspec-related primitives. All uses of
3017 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3019 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3021 * profiler.c (handle_profiler_signal): Fix a malloc race
3022 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3024 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3026 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3028 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3030 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3031 consistent with the change in return value of 'safe_strsignal'.
3033 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3035 Prefer plain 'static' to 'static inline' (Bug#12541).
3036 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3037 (bidi_set_sor_type, bidi_push_embedding_level)
3038 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3039 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3040 (bidi_cache_search, bidi_cache_ensure_space)

3042 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3043 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3044 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3045 Now 'static', not 'static inline'.
3047 Count overruns when profiling; change units to ns.
3048 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3049 Give extra weight to samples after overruns, to attempt to count
3050 the time more accurately.
3051 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3052 the underlying primitives nominally do ns.
3053 (Fprofiler_cpu_start): Document the change. Mention that
3054 the sampling intervals are only approximate.
3056 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3058 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3060 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3061 case for the special 0 coding-system.
3063 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3064 (Fmake_overlay): Remove redundant tests.
3065 (fix_start_end_in_overlays): Remove redundant recentering.
3067 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3069 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3070 Update dependencies.
3072 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3074 Fix a malloc race condition involving strsignal.
3075 A signal can arrive in the middle of a malloc, and Emacs's signal
3076 handler can invoke strsignal, which can invoke malloc, which is
3077 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3078 Fix it by altering the signal handler so that it does not invoke
3080 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3081 * process.c (status_message): Use const pointer, in case strsignal
3082 is #defined to safe_strsignal.
3083 * sysdep.c (sys_siglist, init_signals): Always define and
3084 initialize a substitute sys_siglist if the system does not define
3085 one, even if HAVE_STRSIGNAL.
3086 (safe_strsignal): Rename from strsignal. Always define,
3087 using sys_siglist. Return a const pointer.
3088 * syssignal.h (safe_strsignal): New decl.
3089 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3091 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3093 * w32proc.c (timer_loop): Fix code that waits for timer
3094 expiration, to avoid high CPU usage.
3096 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3098 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3099 (sweep_weak_table): Remove redundant prototypes.
3101 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3103 * emacs.c: Move the inclusion of TERM_HEADER after including
3104 windows.h on WINDOWSNT. This avoids compilation problems with
3107 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3109 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3110 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3111 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3112 as the previous version used 'void *'.
3114 * ralloc.c (ROUNDUP): Fix last change.
3115 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3118 * w32proc.c <disable_itimers>: New static flag.
3119 (init_timers): Initialize it to zero, after creating the critical
3120 sections used by the timer threads.
3121 (term_timers): Set to 1 before deleting the critical sections.
3122 (getitimer, setitimer): If disable_itimers is non-zero, return an
3123 error indication without doing anything. Reported by Fabrice
3124 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3125 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3127 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3130 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3131 term_ntproc after all the other bookkeeping, to get timers working
3132 as long as possible.
3134 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3136 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3137 Suggested by Juri Linkov in
3138 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3140 Prefer plain 'static' to 'static inline' (Bug#12541).
3141 With static functions, modern compilers inline pretty well by
3142 themselves; advice from programmers often hurts as much as it helps.
3143 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3144 this change shrinks the text size of the Emacs executable by 1.1%
3145 without affecting CPU significantly in my benchmark.
3146 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
3147 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

3221 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
3222 Now 'static', not 'static inline'.
3225 (bidi_copy_it): Do the whole copy with a single memcpy.
3226 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3228 Revert the FOLLOW-SYMLINKS change for file-attributes.
3229 Doing it right would require several changes to Tramp, and there's
3230 not enough time to get that tested before the freeze today.
3231 * dired.c (directory_files_internal, Ffile_attributes):
3234 * frame.c (x_report_frame_params): Port better to wider ints.
3235 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3236 or that pointers can be printed in 15 decimal digits.
3237 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3241 Support x64 build on MS-Windows.
3242 * w32term.h (SCROLL_BAR_PACK, SCROLL_BAR_UNPACK): Define for x64.

3251 arithmetics for compatibility with x64.
3253 * w32menu.c (add_menu_item): Use UINT_PTR instead of UINT, for
3254 compatibility with x64.
3256 * w32heap.h: Adjust prototypes and declarations.
3258 * w32heap.c (RVA_TO_PTR, allocate_heap, sbrk, init_heap)
3259 (round_heap): Use DWORD_PTR, ptrdiff_t and size_t instead of

3439 (handle_profiler_signal): Rename from sigprof_handler_1,
3440 for consistency with other handlers. Do not check whether
3441 cpu_log is a hash-table if garbage collecting, since it

3447 Prefer timer_settime if available, and prefer
3448 thread cputime clocks, then process cputime clocks, then
3449 monotonic clocks, to the old realtime clock. Use make_timeval
3450 to round more-correctly when falling back to setitimer.
3451 (Fprofiler_cpu_start): Use it.
3452 (Fprofiler_cpu_stop): Prefer timer_settime if available.

3722 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3724 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3725 fatal_error_backtrace.
3727 * w32proc.c (sys_kill): Undo last change: don't do anything when
3728 invoked to deliver SIGABRT to our own process. This is now
3729 handled by emacs_raise.
3731 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3733 * w32term.c (w32_read_socket): Remove leftover reference to
3734 interrupt_input_pending.
3736 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3738 Do not use SA_NODEFER.
3739 Problem reported by Dani Moncayo in
3740 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3742 * sysdep.c (emacs_abort): Do not reset signal handler.
3743 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3744 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3745 wanted even on POSIXish hosts, and it doesn't work on Windows.
3747 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3749 * xterm.c (x_term_init): Call fixup_locale before and after calling
3750 gtk_init (Bug#12392).
3752 2012-09-23 Chong Yidong <cyd@gnu.org>
3754 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3755 Vdynamic_library_alist.
3757 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3758 (Fgnutls_available_p): Caller changed.
3760 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3761 (Flibxml_parse_xml_region): Likewise.
3763 * dispextern.h (struct image_type): Remove arg from init function.
3765 * image.c (Finit_image_library, lookup_image_type)
3766 (define_image_type): Remove now-unneeded second arg.
3767 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3768 (init_tiff_functions, init_gif_functions, init_svg_functions):
3769 Arglist and w32_delayed_load calling convention changed.
3770 (gs_type): Remove init_gs_functions; there is no such function.
3771 (valid_image_p, make_image): Fix caller to lookup_image_type.
3773 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3775 Simplify and avoid signal-handling races (Bug#12471).
3777 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3778 Avoid recursive loop if there's a fatal error in the function itself.
3779 * atimer.c (pending_atimers):
3780 * blockinput.h: Don't include "atimer.h"; no longer needed.
3781 (interrupt_input_pending): Remove. All uses removed.
3782 pending_signals now counts both atimers and ordinary interrupts.
3783 This is less racy than having three separate pending-signal flags.
3784 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3786 Rename from their upper-case counterparts BLOCK_INPUT,
3787 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3788 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3789 This makes it easier to access volatile variables more accurately.
3790 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3791 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3792 that's more reliable if the code is buggy and sets
3793 interrupt_input_blocked to a negative value. All uses changed.
3794 * atimer.c (deliver_alarm_signal):
3795 Remove. No need to deliver this to the parent; any thread can
3796 handle this signal now. All uses replaced by underlying handler.
3797 * atimer.c (turn_on_atimers):
3798 * dispnew.c (handle_window_change_signal):
3799 * emacs.c (handle_danger_signal):
3800 * keyboard.c (kbd_buffer_get_event):
3801 Don't reestablish signal handler; not needed with sigaction.
3802 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3804 Rework to avoid unnecessary accesses to volatile variables.
3805 (UNBLOCK_INPUT_TO): Now a function.
3806 (totally_unblock_input, unblock_input): New decls.
3807 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3808 (init_data): Remove. Necessary stuff now done in init_signal.
3809 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3810 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3811 (fatal_error_code): Remove; no longer needed.
3812 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3813 it doesn't always backtrace. All uses changed. No need to reset
3814 signal to default, since sigaction and/or die does that for us now.
3815 Use emacs_raise (FOO), not kill (getpid (), FOO).
3816 (main): Check more-accurately whether we're dumping.
3817 Move fatal-error setup to sysdep.c
3818 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3819 * gtkutil.c (xg_get_file_name, xg_get_font):
3820 Remove no-longer-needed signal-mask manipulation.
3821 * keyboard.c, process.c (POLL_FOR_INPUT):
3822 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3823 * keyboard.c (read_avail_input): Remove.
3824 All uses replaced by gobble_input.
3825 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3826 (kbd_buffer_store_event_hold, gobble_input):
3827 (record_asynch_buffer_change) [USABLE_SIGIO]:
3828 (store_user_signal_events):
3829 No need to mess with signal mask.
3830 (gobble_input): If blocking input and there are terminals, simply
3831 set pending_signals to 1 and return. All hooks changed to not
3832 worry about whether input is blocked.
3833 (process_pending_signals): Clear pending_signals before processing
3834 them, in case a signal comes in while we're processing.
3835 By convention callers now test pending_signals before calling us.
3836 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3837 New functions, to support changes to blockinput.h.
3838 (handle_input_available_signal): Now extern.
3839 (reinvoke_input_signal): Remove. All uses replaced by
3841 (quit_count): Now volatile, since a signal handler uses it.
3842 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3843 All callers changed. Block SIGINT only if not already blocked.
3844 Clear sigmask reliably, even if Fsignal returns, which it can.
3845 Omit unnecessary accesses to volatile var.
3846 (quit_throw_to_read_char): No need to restore sigmask.
3847 * keyboard.c (gobble_input, handle_user_signal):
3848 * process.c (wait_reading_process_output):
3849 Call signal-handling code rather than killing ourselves.
3850 * lisp.h: Include <float.h>, for...
3851 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3852 (pending_signals): Now volatile.
3853 (syms_of_data): Now const if IEEE floating point.
3854 (handle_input_available_signal) [USABLE_SIGIO]:
3855 (terminate_due_to_signal, record_child_status_change): New decls.
3856 * process.c (create_process): Avoid disaster if memory is exhausted
3857 while we're processing a vfork, by tightening the critical section
3859 (send_process_frame, process_sent_to, handle_pipe_signal)
3860 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3862 (send_process): No need for setjmp/longjmp any more, since the
3863 SIGPIPE stuff is now gone. Instead, report an error if errno
3865 (record_child_status_change): Now extern. PID and W are now args.
3866 Return void, not bool. All callers changed.
3867 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3868 Remove. All uses removed. This bug should be fixed now in a
3870 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3871 and record the child status change directly. This avoids the
3872 need to futz with the signal mask.
3873 (process_fatal_action): Move here from emacs.c.
3874 (emacs_sigaction_flags): New function, containing
3875 much of what used to be in emacs_sigaction_init.
3876 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3877 caught by emacs, to make races less likely.
3878 (deliver_process_signal): Rename from handle_on_main_thread.
3880 (BACKTRACE_LIMIT_MAX): Now at top level.
3881 (thread_backtrace_buffer, threadback_backtrace_pointers):
3883 (deliver_thread_signal, deliver_fatal_thread_signal):
3884 New functions, for more-accurate delivery of thread-specific signals.
3885 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3886 (deliver_arith_signal): Handle in this thread, not
3887 in the main thread, since it's triggered by this thread.
3888 (maybe_fatal_sig): New function.
3889 (init_signals): New arg DUMPING so that we can be more accurate
3890 about whether we're dumping. Caller changed.
3891 Treat thread-specific signals differently from process-general signals.
3892 Block all signals while handling fatal error; that's safer.
3893 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3895 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3896 Ignore SIGPIPE unless batch.
3897 (emacs_backtrace): Output backtrace for the appropriate thread,
3898 which is not necessarily the main thread.
3899 * syssignal.h: Include <stdbool.h>.
3900 (emacs_raise): New macro.
3901 * xterm.c (x_connection_signal): Remove; no longer needed
3902 now that we use sigaction.
3903 (x_connection_closed): No need to mess with sigmask now.
3904 (x_initialize): No need to reset SIGPIPE handler here, since
3905 init_signals does this for us now.
3907 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3909 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3910 background rect may be larger (Bug#12245).
3912 2012-09-23 Chong Yidong <cyd@gnu.org>
3914 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3916 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3918 * .gdbinit: Just stop at fatal_error_backtrace.
3919 See Stefan Monnier's request in
3920 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3921 Remove no-longer-used query of system type.
3923 2012-09-22 Chong Yidong <cyd@gnu.org>
3925 * search.c (Freplace_match): Doc fix (Bug#12325).
3927 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3929 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3930 (Fline_end_position): Doc fix.
3932 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3934 2012-09-22 Chong Yidong <cyd@gnu.org>
3936 * dispextern.h (struct image_type): Add new slot, storing a type
3937 initialization function.
3939 * image.c (define_image_type): Call the image initializer function
3940 if it is defined. Arguments and return value changed.
3941 (valid_image_p, make_image): Callers changed.
3942 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3943 (gif_type, imagemagick_type, svg_type, gs_type):
3944 Add initialization functions.
3945 (Finit_image_library): Call lookup_image_type.
3946 (CHECK_LIB_AVAILABLE): Macro deleted.
3947 (lookup_image_type): Call define_image_type here, rather than via
3948 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3949 (syms_of_image): Move define_image_type calls for xbm_type and
3950 pbm_type to lookup_image_type.
3952 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3954 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3955 'idle_timers' from here ...
3956 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3957 lists, to avoid infloops when the timer does something stupid,
3958 like reinvoke itself with the same or smaller time-out.
3961 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3963 * window.c (Fsplit_window_internal): Handle only Qt value of
3964 Vwindow_combination_limit separately.
3965 (Qtemp_buffer_resize): New symbol.
3966 (Vwindow_combination_limit): New default value.
3969 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3971 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3972 the new overlay string. (Bug#10159)
3974 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3976 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3977 or that fprintf is async-signal-safe. POSIX doesn't require
3980 2012-09-22 Chong Yidong <cyd@gnu.org>
3982 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3985 2012-09-22 Kenichi Handa <handa@gnu.org>
3987 * composite.c (composition_reseat_it): Handle the case that a
3988 grapheme cluster is not covered by a single font (Bug#12352).
3990 2012-09-21 Chong Yidong <cyd@gnu.org>
3992 * image.c (define_image_type): Avoid adding duplicate types to
3993 image_types (Bug#12463). Suggested by Jörg Walter.
3995 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3997 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3998 (print_load_command_name): Add case LC_DATA_IN_CODE.
3999 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4001 2012-09-21 Glenn Morris <rgm@gnu.org>
4003 * eval.c (Frun_hook_with_args_until_success)
4004 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4006 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4008 * fileio.c (Ffile_selinux_context): Only call freecon when
4009 lgetfilecon succeeded.
4010 (Fset_file_selinux_context): Likewise. (Bug#12444)
4012 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4014 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4015 reordering, locate the cursor by calling set_cursor_from_row; if
4016 that fails, clear the desired glyph matrix before returning a
4017 failure indication to the caller. Fixes leaving garbled display
4018 when fast scrolling with a down-key. (Bug#12403)
4019 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4020 scrolling through multibyte text.
4022 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4024 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4025 calling mark_vectorlike since that's the one that marks the window.
4026 (mark_discard_killed_buffers): Mark the final cdr.
4027 * window.h (struct window): Move prev/next_buffers to the
4028 non-standard fields.
4029 * window.c (make_window): Initialize prev/next_buffers manually.
4031 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4033 Omit unused arg EXPECTED from socket hooks.
4034 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4035 * nsterm.m (ns_term_init):
4036 * termhooks.h (struct terminal.read_socket_hook):
4037 * w32inevt.c (w32_console_read_socket):
4038 * w32term.c (w32_read_socket):
4039 * xterm.c (XTread_socket):
4040 Omit unused arg EXPECTED. All callers changed.
4041 (store_user_signal_events): Return void, not int, since callers no
4042 longer care about the return value. All uses changed.
4044 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4046 * w32gui.h (XParseGeometry): Do not declare.
4048 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4050 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4051 Ignore 'expected'. See Eli Zaretskii in
4052 <http://bugs.gnu.org/12471#8> (last line).
4054 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4055 (XParseGeometry): Now static. Substitute extremal values for
4056 values that are out of range.
4058 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4060 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4062 * nsfns.m (XParseGeometry): Remove.
4063 (Fx_create_frame): Call x_set_offset to correctly interpret
4064 top_pos in geometry.
4066 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4067 (Fx_parse_geometry): If there is a space in string, call
4068 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4070 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4072 * search.c (scan_buffer): Use character positions in calls to
4073 region_cache_forward and region_cache_backward, not byte
4074 positions. (Bug#12196)
4076 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4077 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4079 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4080 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4081 emacs_blocked_malloc, now deleted.
4083 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4085 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4086 The workaround was for improving performance on Solaris 2.4, but
4087 is getting in the way now. Emacs will still work if someone is
4088 still running Solaris 2.4 in a museum somewhere; Sun dropped
4089 support for Solaris 2.4 in 2003.
4090 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4091 * process.c (create_process) [HAVE_WORKING_VFORK]:
4092 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4093 since Emacs no longer uses vfork on that platform.
4095 2012-09-17 Glenn Morris <rgm@gnu.org>
4097 * emacs.c: Use COPYRIGHT.
4099 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4101 Remove configure's --without-sync-input option (Bug#12450).
4102 When auditing signal-handling in preparation for cleaning it up,
4103 I found that SYNC_INPUT has race conditions and would be a real
4104 pain to fix. Since it's an undocumented and deprecated
4105 configure-time option, now seems like a good time to remove it.
4106 Also see <http://bugs.gnu.org/11080#16>.
4107 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4108 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4109 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4110 (malloc_hysteresis):
4111 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4112 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4113 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4114 (dont_register_blocks, bytes_used_when_reconsidered)
4115 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4116 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4117 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4118 Remove. All uses removed.
4119 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4120 implementation, one that depends on whether the new macro
4121 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4123 * atimer.c (run_timers, handle_alarm_signal):
4124 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4125 (handle_async_input, process_pending_signals)
4126 (handle_input_available_signal, init_keyboard):
4127 * nsterm.m (ns_read_socket):

4132 * xterm.c (XTread_socket):
4134 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4135 * eval.c (handling_signal): Remove. All uses removed.
4136 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4137 All uses replaced with the SYNC_INPUT version.
4138 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4140 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4143 * font.c (Ffont_shape_gstring): Remove unused local.
4145 2012-09-16 Glenn Morris <rgm@gnu.org>
4147 * Makefile.in (clean): No longer run nextstep's clean.
4149 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4151 (ns-app): Move here from ns.mk, and simplify.
4152 (clean): Simplify nextstep entry.
4153 * ns.mk: Remove file.
4155 2012-09-17 Kenichi Handa <handa@gnu.org>
4157 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4158 not covert the last few charactes.
4160 2012-09-16 Kenichi Handa <handa@gnu.org>
4162 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4163 here, but just check the validity of glyphs in the glyph-string.
4165 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4167 * window.c (Fwindow_parameter, Fset_window_parameter):
4168 Accept any window as argument (Bug#12452).
4170 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4172 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4173 to ns_term_init to avoid memory leak.
4175 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4176 explicit retain/release.
4177 (ns_term_init): Only allow one display. Initialize outerpool and
4180 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4182 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4183 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4184 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4185 the Microsoft problem in a different way, by altering ../nt/config.nt.
4187 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4202 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4203 by lisp.h. This completes removal of setjmp.h inclusion
4204 erroneously announced in the previous commit. (Bug#12446)
4206 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4209 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4210 not defined as a macro. The latter happens on MS-Windows.
4213 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4215 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4216 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4217 Some instances of '#include <setjmp.h>' removed, if the
4218 only reason for the instance was because "lisp.h" was included.
4219 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4220 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4221 and _longjmp with the new symbols. Emacs already uses _setjmp if
4222 available, so this change affects only POSIXish hosts that have
4223 sigsetjmp but not _setjmp, such as some versions of Solaris and
4224 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4225 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4226 (png_load_body) [HAVE_PNG]:
4227 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4228 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4229 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4230 since PNG requires jmp_buf. This is the only exception to the
4231 general rule that we now use sys_setjmp and sys_longjmp.
4232 This exception is OK since this code does not change the signal
4233 mask or longjmp out of a signal handler.
4235 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4237 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4238 Include "syssignal.h", for 'main_thread'.
4240 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4242 Avoid out-of-range marker position (Bug#12426).
4243 * insdel.c (replace_range, replace_range_2):
4244 Adjust markers before overlays, as suggested by comments.
4245 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4246 Remove redundant check before calling offset_intervals.
4248 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4250 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4251 current buffer (Bug#12387).
4253 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4255 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4257 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4259 Use a more backwards-compatible timer format (Bug#12430).
4260 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4261 vector element, not from the 4th, since PSECS is now at the end.
4262 (Fcurrent_idle_time): Doc fix.
4264 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4266 Function to mark objects and remove killed buffers at once.
4267 * alloc.c (discard_killed_buffers): Rename to ...
4268 (mark_discard_killed buffers) ... new name. Add marking
4269 of remaining objects. Fix comment. Adjust users.
4270 (mark_object): Do not touch frame buffer lists here.
4271 * frame.c (delete_frame): Reset frame buffer lists here.
4273 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4275 Better workaround for GNOME bug when --enable-gcc-warnings.
4276 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4277 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4278 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4280 Simplify SIGIO usage (Bug#12408).
4281 The code that dealt with SIGIO was crufty and confusing, e.g., it
4282 played tricks like "#undef SIGIO" but these tricks were not used
4283 consistently. Simplify mostly by not #undeffing standard symbols,
4284 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4285 or not as we please) rather than "defined SIGIO" (standard symbol
4286 that we probably shouldn't #undef).
4287 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4288 Modules that need it can include it.
4289 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4290 * dispextern.h (ignore_sigio): New decl.
4291 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4292 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4293 * emacs.c (shut_down_emacs):
4294 * keyboard.c (kbd_buffer_store_event_hold):
4295 Use ignore_sigio rather than invoking 'signal' directly.
4296 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4298 (FIONREAD, SIGIO): Do not #undef.
4299 (tty_read_avail_input): Use #error rather than a syntax error.
4300 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4301 for I_PIPE, used by SETUP_SLAVE_PTY.
4302 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4303 * sysdep.c (croak): Remove; no longer needed. This bit of
4304 temporary code, with Fred N. Fish's comment that it's temporary,
4305 has been in Emacs since at least 1992!
4306 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4307 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4308 * syssignal.h (croak): Remove decl.
4309 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4310 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4311 now that we're termios-only.
4312 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4313 * term.c (dissociate_if_controlling_tty): Use #error rather than
4316 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4317 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4318 to work around GNOME bug 683906.
4319 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4320 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4321 This works around GCC bug 54561.
4323 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4325 More fixes for 'volatile' and setjmp/longjmp.
4326 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4327 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4328 (png_load_body) [HAVE_PNG]:
4329 (jpeg_load_body) [HAVE_JPEG]:
4330 New function, with most of the old parent function's body.
4331 (png_load) [HAVE_PNG]:
4332 (jpeg_load) [HAVE_JPEG]:
4333 Invoke the new function, to avoid longjmp munging our locals.
4334 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4335 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4336 longjmp is passed 2, as the C standard doesn't guarantee this.
4337 Instead, store the failure code into mgr->failure_code.
4339 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4341 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4342 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4343 (syms_of_keyboard): Remove support for unread-command-char.
4345 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4347 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4348 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4349 violation. (Bug#12426)
4351 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4353 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4355 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4357 * eval.c: Add `inhibit-debugger'.
4358 (Qinhibit_debugger): New symbol.
4359 (call_debugger): Bind it instead of Qdebug_on_error.
4360 (maybe_call_debugger): Test Vinhibit_debugger.
4361 (syms_of_eval): Define inhibit-debugger.
4362 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4363 (syms_of_xdisp): Remove inhibit-debug-on-message.
4365 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4367 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4368 If a nonvolatile local variable is written before a _longjmp to
4369 the frame containing the variable, and is read after the _longjmp,
4370 the value read is indeterminate. Some local variables of type
4371 'struct handler' and 'struct catchtag' are used in this way, so
4372 mark each of their slots as volatile if the slot can be set before
4373 _longjmp and read afterwards.
4374 * lisp.h (struct handler): var and chosen_clause are now volatile.
4375 (struct catchtag): val, next, and pdlcount are now volatile.
4377 * bidi.c (bidi_push_it, bidi_pop_it):
4378 * fns.c (copy_hash_table):
4379 * image.c (define_image_type):
4380 * keyboard.c (kbd_buffer_store_event_hold):
4381 * process.c (Fprocess_send_eof):
4382 * xfaces.c (x_create_gc) [HAVE_NS]:
4383 * xgselect.c (xg_select):
4384 Prefer assignment to memcpy when either will do.
4386 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4387 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4388 time an item is removed. No need to mark this function 'inline';
4389 the compiler knows better than we do.
4391 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4393 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4394 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4395 to change_frame_size (Bug#12388).
4396 (windowDidResize:): Pass YES to updateFrameSize.
4398 * nsterm.h: Add delay parameter to updateFrameSize.
4400 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4402 Discard killed buffers from deleted window and frame objects.
4403 This reduces an amount of references to killed buffers and
4404 helps GC to reclaim them faster.
4405 * alloc.c (discard_killed_buffers): New function.
4406 (mark_object): Use it for deleted windows and frames.
4407 (mark_object): If symbol's value is set up for a killed buffer
4408 or deleted frame, restore its global binding.
4409 * data.c (swap_in_global_binding): Add GC notice.
4410 (swap_in_symval_forwarding): Use convenient set_blv_where.
4411 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4412 * window.h: ... to here.
4414 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4416 Convenient macro to check whether the buffer is live.
4417 * buffer.h (BUFFER_LIVE_P): New macro.
4418 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4419 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4421 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4423 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4424 composition cases (Bug#12364).
4426 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4427 overhang of succeeding glyphs overlapping box cursor.
4429 * w32term.c (x_draw_glyph_string): Likewise.
4431 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4433 Simplify, document, and port floating-point (Bug#12381).
4434 The porting part of this patch fixes bugs on non-IEEE platforms
4435 with frexp, ldexp, logb.
4436 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4438 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4439 support, by removing commented-out code and briefly listing the
4440 C89 functions excluded. The commented-out stuff was confusing
4441 maintenance, e.g., we thought we needed cbrt but it was commented out.
4442 (logb): Remove decl; no longer needed.
4443 (isfinite): New macro, if not already supplied.
4444 (isnan): Don't replace any existing macro.
4445 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4446 are present on all C89 platforms.
4447 (Ffrexp): Do not special-case zero, as frexp does the right thing
4449 (Flogb): Do not use logb, as it doesn't have the desired meaning
4450 on hosts that use non-base-2 floating point. Instead, stick with
4451 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4452 frexp, to avoid getting an unspecified result.
4454 * xdisp.c (Qinhibit_debug_on_message): Now static.
4456 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4458 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4459 NSBezierPath (Bug#12131).
4461 2012-09-10 Chong Yidong <cyd@gnu.org>
4463 * fns.c (Fdelq, Fdelete): Doc fix.
4465 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4467 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4468 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4470 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4472 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4473 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4476 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4478 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4479 left fringe if the window has a left margin. This avoids leaving
4480 traces of the cursor because its leftmost pixel is not drawn over.
4482 * dispnew.c (update_window_line): When the left margin area of a
4483 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4484 that screen line. (Bug#12277)
4486 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4488 Assume C89 or later for math functions (Bug#12381).
4489 This simplifies the code, and makes it a bit smaller and faster,
4490 and (most important) makes it easier to clean up signal handling
4491 since we can stop worring about floating-point exceptions in
4492 library code. That was a problem before C89, but the problem
4493 went away many years ago on all practical Emacs targets.
4494 * data.c, image.c, lread.c, print.c:
4495 Don't include <math.h>; no longer needed.
4496 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4497 might be autoconfigured, as that never happens.
4499 * doprnt.c (DBL_MAX_10_EXP):
4500 * print.c (DBL_DIG):
4501 Remove. C89 or later always defines these.
4502 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4503 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4504 (arith_error, domain_error, domain_error2):
4505 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4506 no longer needed -- we simply return what C returns. All uses removed.
4507 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4509 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4510 Remove. All uses expanded, as these macros are no longer used
4511 more than once and are now more trouble than they're worth.
4512 (Ftan): Use tan, not sin / cos.
4513 (Flogb): Assume C89 frexp.
4514 (fmod_float): Assume C89 fmod.
4515 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4516 (init_floatfns): Remove. All uses removed.
4518 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4520 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4521 compositeToPoint for OSX < 10.6 (Bug#12390).
4523 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4525 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4526 This produces more-accurate results.
4528 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4530 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4531 changes (Bug#12088).
4533 2012-09-08 Chong Yidong <cyd@gnu.org>
4535 * syntax.c (Fstring_to_syntax): Doc fix.
4537 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4539 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4540 in the internal border.
4541 (x_set_window_size): Remove static variables and their usage.
4542 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4543 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4544 Remove fringe/internal border adjustment (Bug#11052).
4545 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4546 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4547 (ns_fix_rect_ibw): Remove.
4548 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4549 (ns_dumpglyphs_box_or_relief): Ditto.
4550 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4552 (ns_dumpglyphs_image): Ditto.
4553 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4555 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4556 their usage. Add fringe_extended_p and its use as in other terms.
4557 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4558 scroll bar was removed.
4559 (updateFrameSize): New function.
4560 (windowDidResize): Move code to updateFrameSize and call it.
4562 * nsterm.h (EmacsView): Add updateFrameSize.
4564 2012-09-07 Chong Yidong <cyd@gnu.org>
4566 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4568 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4570 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4572 More signal-handler cleanup (Bug#12327).
4573 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4574 Problem introduced when merging patches. Noted by Eli Zaretskii in
4575 <http://bugs.gnu.org/12327#67>.
4576 * floatfns.c: Comment fix.
4577 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4578 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4579 and anyway the declaration is harmless even if SIGDANGER is not defined.
4580 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4581 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4582 source files not surprisingly expected syssignal.h to define, or
4583 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4584 Include <sys/ioctl.h>, for FIONREAD.
4585 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4586 This eliminates a problem whereby other files mysteriously had
4587 to include "syssignal.h" before including "systty.h" if they
4588 wanted to use "#ifdef SIGIO".
4590 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4592 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4594 * w32.c (sigemptyset): Empty the set.
4595 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4597 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4599 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4601 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4602 (mark_object): Likewise for frame objects.
4604 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4606 * syssignal.h (handle_on_main_thread): Always declare,
4607 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4608 This ports to platforms without HAVE_PTHREAD.

4612 Signal-handler cleanup (Bug#12327).
4613 Emacs's signal handlers were written in the old 4.2BSD style with
4614 sigblock and sigmask and so forth, and this led to some
4615 inefficiencies and confusion. Rewrite these to use
4616 pthread_sigmask etc. without copying signal sets around. Also,
4617 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4618 'signal', and instead use functions that do not attempt to take
4619 over the system name space. This patch causes Emacs's text
4620 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4621 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4622 Do not include <signal.h> or "syssignal.h", as these
4623 modules do not use signals.
4624 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4625 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4626 Do not include <signal.h>, as "syssignal.h" does that for us now.
4627 * atimer.c (sigmask_atimers): New function.
4628 (block_atimers, unblock_atimers): New functions,
4629 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4631 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4632 no longer needed here.
4633 * emacs.c (main): Inspect existing signal handler with sigaction,
4634 so that there's no need to block and unblock SIGHUP.
4635 * sysdep.c (struct save_signal): New member 'action', replacing
4636 old member 'handler'.
4637 (save_signal_handlers, restore_signal_handlers):
4638 Use sigaction instead of 'signal' to save and restore.
4639 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4640 New function. All users of 'signal' modified to use set_sighandler
4641 if they're writeonly, and to use sys_signal if they're read+write.
4642 (emacs_sigaction_init, forwarded_signal): New functions.
4643 (sys_signal): Remove. All uses replaced by calls to sigaction
4644 and emacs_sigaction_init, or by direct calls to 'signal'.
4645 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4646 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4647 all uses replaced by pthread_sigmask etc. calls.
4648 * syssignal.h: Include <signal.h>.
4649 (emacs_sigaction_init, forwarded_signal): New decls.
4650 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4651 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4652 (sigmask, sys_sigmask): Remove; no longer needed.
4653 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4654 (sigblock, sigunblock, sigfree):
4655 (sigsetmask) [!defined sigsetmask]:
4656 Remove. All uses replaced by pthread_sigmask.
4657 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4658 no longer need to be replaced, and its typical old uses
4659 are now done via emacs_sigaction_init and sigaction.
4660 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4661 (sys_sigdel): Remove; unused.
4662 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4664 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4666 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4667 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4669 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4671 Explicitly mark buffer_defaults and buffer_local_symbols.
4672 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4673 mark_local_symbols here.
4674 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4675 since special buffers aren't marked here any more.
4676 (allocate_buffer): Chain new buffer with all_buffers here...
4677 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4679 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4680 (syms_of_buffer): Remove staticpro of the above.
4681 (init_buffer_once): Set names for buffer_defaults and
4682 buffer_local_symbols.
4684 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4686 Use bool for booleans in font-related modules.
4687 * font.c (font_intern_prop, font_style_to_value)
4688 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4689 (generate_otf_features, font_check_otf_features, font_check_otf)
4690 (font_match_p, font_list_entities, font_at):
4691 * fontset.c (fontset_id_valid_p, reorder_font_vector
4692 (fontset_find_font, Fset_fontset_font)
4693 (face_suitable_for_char_p) [0]:
4694 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4695 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4696 (m17n_flt_initialized, ftfont_shape_by_flt):
4697 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4698 * nsfont.m (nsfont_draw):
4699 * w32font.c (w32font_draw):
4700 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4701 Use bool for booleans.
4702 * font.h: Adjust to above API changes.
4703 (struct font, struct font_driver, struct font_driver_list):
4704 Use bool for booleans.
4705 (struct font): Remove useless member encoding_type.
4707 * fontset.c, xftfont.c: Omit unnecessary static decls.
4709 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4711 * alloc.c (mark_object): Revert window marking code
4712 since it's unsafe for the Fset_window_configuration.
4714 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4716 Fix race conditions with signal handlers and errno (Bug#12327).
4717 Be more systematic about preserving errno whenever a signal
4718 handler returns, even if it's not in the main thread. Do this by
4719 renaming signal handlers to distinguish between signal delivery
4720 and signal handling. All uses changed.
4721 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4722 * data.c (deliver_arith_signal): Rename from arith_error.
4723 * dispnew.c (deliver_window_change_signal): Rename from
4724 window_change_signal.
4725 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4726 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4727 * keyboard.c (deliver_input_available_signal): Rename from
4728 input_available_signal.
4729 (deliver_user_signal): Rename from handle_user_signal.
4730 (deliver_interrupt_signal): Rename from interrupt_signal.
4731 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4732 (deliver_child_signal): Rename from sigchld_handler.
4733 * atimer.c (handle_alarm_signal):
4734 * data.c (handle_arith_signal):
4735 * dispnew.c (handle_window_change_signal):
4736 * emacs.c (handle_fatal_signal, handle_danger_signal):
4737 * keyboard.c (handle_input_available_signal):
4738 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4739 * process.c (handle_pipe_signal, handle_child_signal):
4740 New functions, with the actual signal-handling code taken from the
4741 original respective signal handlers, sans the sporadic attempts to
4742 preserve errno, since that's now done by handle_on_main_thread.
4743 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4744 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4745 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4747 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4748 Move initialization of main_thread to sysdep.c's init_signals.
4749 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4750 our usage, and simplifies the mainline code.
4751 (record_child_status_change): New static function, as a helper
4752 for handle_child_signal, and with most of the old child handler's
4754 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4755 (handle_child_signal): Use the above.
4756 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4757 Moved here from emacs.c.
4758 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4759 code moved here from emacs.c's main function.
4760 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4761 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4762 This lets callers save and restore errno properly.
4764 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4766 Remove redundant or unused things here and there.
4767 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4768 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4769 * editfns.c (Fcompare_buffer_substrings): Likewise.
4770 * frame.h (struct terminal, struct font_driver_list):
4771 Remove redundant declarations.
4772 * window.h (Qleft, Qright): Likewise.
4774 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4776 Do not mark objects from deleted buffers, windows and frames.
4777 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4778 (mark_object): Likewise for windows and frames.
4780 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4782 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4783 buffer_defaults and buffer_local_symbols as valid objects.
4784 Return special value to denote them.
4786 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4788 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4789 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4790 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4791 (file_name_absolute_p, Fsubstitute_in_file_name):
4792 (check_executable, check_writable, Ffile_accessible_directory_p)
4793 (Fset_file_selinux_context, Fdefault_file_modes)
4794 (Finsert_file_contents, choose_write_coding_system)
4795 (Fwrite_region, build_annotations, a_write, e_write)
4797 * filelock.c (boot_time_initialized, get_boot_time)
4798 (get_boot_time_1, lock_file_1, within_one_second):
4799 * floatfns.c (in_float):
4800 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4801 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4802 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4803 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4804 * window.c (compare_window_configurations):
4805 Use bool for booleans.
4806 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4807 (Fdefault_file_modes): Now mode_t, not int, for modes.
4808 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4809 (internal_delete_file): Now returns void, not a (boolean) int,
4810 since nobody was looking at the return value.
4811 * lisp.h, window.h: Adjust to above API changes.
4813 * xdisp.c (set_message): Simplify and reindent last change.
4815 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4817 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4819 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4821 * eval.c (call_debugger): Make the function non-static so that we
4822 can call it from set_message.
4824 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4825 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4827 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4829 Give more-useful info on a fatal error (Bug#12328).
4830 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4831 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4832 of doing the work ourselves.
4833 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4834 do most of the work.
4835 (fatal_error_backtrace): New function, taken from the guts
4836 of the old fatal_error_signal, but with a new option to output
4838 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4839 info about the signal than just its number.
4840 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4841 * sysdep.c: Include <execinfo.h>
4842 (emacs_backtrace): New function, taken partly from the previous
4843 code of the 'die' function.
4844 (emacs_abort): Call fatal_error_backtrace rather than abort.
4846 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4848 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4849 eager (load-time) macro-expansion.
4850 * lisp.mk (lisp): Add macroexp.
4852 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4854 Simplify redefinition of 'abort' (Bug#12316).
4855 Do not try to redefine the 'abort' function. Instead, redo
4856 the code so that it calls 'emacs_abort' rather than 'abort'.
4857 This removes the need for the NO_ABORT configure-time macro
4858 and makes it easier to change the abort code to do a backtrace.
4859 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4860 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4861 Remove; sysdep.c's emacs_abort now takes its place.
4862 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4863 'abort' changed to use 'emacs_abort'.
4864 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4865 (abort) [!defined abort]: Rename to ...
4866 (emacs_abort): ... new name.
4867 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4868 the place of the old 'abort' in emacs.c.
4869 * w32.c, w32fns.c (abort): Do not #undef.
4870 * w32.c (emacs_abort): Rename from w32_abort.
4872 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4874 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4875 offsets[j].dv, since the y axis of the screen coordinates points
4876 down, while the y axis of the font definition coordinates points
4877 up. This fixes display of Arabic diacritics such as KASRA and
4878 KASRATAN. (Bug#11860)
4880 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4882 Be more systematic about _setjmp vs setjmp.
4883 * alloc.c (test_setjmp, mark_stack):
4884 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4885 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4886 (png_load, my_error_exit, jpeg_load):
4887 * process.c (send_process_trap, send_process):
4888 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4889 The underscored versions are up to 30x faster on some hosts.
4890 Formerly, the code used setjmp+longjmp sometimes and
4891 _setjmp+_longjmp at other times, with no particular reason to
4892 prefer setjmp+longjmp.
4894 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4896 Fix minor problem found by static checking.
4897 * buffer.c (Fdelete_all_overlays): Return nil.
4899 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4901 * buffer.c (Fdelete_all_overlays): New function.
4903 2012-09-03 Chong Yidong <cyd@gnu.org>
4905 * gtkutil.c: Add extern decl for Qxft.
4907 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4909 * emacs.c, eval.c: Use bool for boolean.
4910 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4911 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4912 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4913 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4914 (main, decode_env_path, Fdaemon_initialized):

4916 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4917 (maybe_call_debugger, Fbacktrace):
4918 * process.c (read_process_output, exec_sentinel):
4919 Use bool for booleans.
4920 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4921 All callers changed.
4922 * eval.c (interactive_p): Omit always-true boolean argument
4923 EXCLUDE_SUBRS_P. All callers changed.
4924 * dispextern.h, lisp.h: Reflect above API changes.
4925 * firstfile.c (dummy): Use the address of 'main', whose signature
4926 won't change, instead of the address of 'initialize', whose
4927 signature just changed from int to bool.
4928 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4929 * msdos.c (fatal_error_in_progress): ... from here.
4930 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4932 (redisplay_internal, unwind_redisplay): Simply clear
4933 REDISPLAYING_P when unwinding, instead of saving its previous,
4934 always-false value and then restoring it.
4936 Clean up some extern decls.
4937 Mostly, this hoists extern decls out of .c files and into .h files.
4938 That way, we're more likely to catch errors if the interfaces change.
4939 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4940 declare xg_mark_data.
4941 * dispextern.h (x_frame_parm_handlers):
4943 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4944 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4945 (Qultra_bold, Qoblique, Qitalic):
4946 Move extern decl here from .c file.
4947 * alloc.c (xg_mark_data) [USE_GTK]:
4949 * eval.c (Qlexical_binding):
4950 * fns.c (time) [!HAVE_UNISTD_H]:
4951 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
4952 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

4956 * process.c (QCfamily, QCfilter):
4957 * widget.c (free_frame_faces):
4958 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4959 * xfont.c (x_clear_errors):
4960 * xterm.c (x_frame_parm_handlers):
4961 Remove now-redundant extern decls.
4962 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4963 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4965 * xfaces.c: Remove unnecessary static decls.
4966 * xterm.c (updating_frame): Remove decl of nonexistent object.
4968 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4969 when building globals.h, as the objects that are not built on
4970 this host are not needed to compile C files on this host.
4972 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4974 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4976 * frame.h: Add missing prototype for x_wm_set_size_hint.
4978 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4980 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.

4982 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4983 (Fsubstitute_command_keys):

4986 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
4987 (format_time_string, general_insert_function)
4988 (make_buffer_string, make_buffer_string_both)
4989 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

5002 * keyboard.c (decode_timer):
5003 Use bool for boolean.
5004 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5005 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5007 2012-09-02 Chong Yidong <cyd@gnu.org>
5009 * keymap.c (push_key_description): Print M-TAB as C-M-i
5012 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5014 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

5022 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5024 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5025 more than one grapheme cluster passed to the shaper: compute the
5026 offset adjustment values separately for each cluster. (Bug#11860)
5028 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5029 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5030 about implicit conversions from integer to pointer.
5032 2012-09-01 Daniel Colascione <dancol@dancol.org>
5034 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

5050 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
5051 x_wm_set_size_hint, x_query_colors, x_real_positions,
5052 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
5053 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
5054 all of which have been moved to common code.
5056 * xfaces.c: Include TERM_HEADER instead of listing all possible
5057 window-system headers.
5059 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

5080 * keyboard.c: Include TERM_HEADER instead of listing all possible
5081 window-system headers.
5083 * image.c: Include TERM_HEADER instead of listing all possible
5084 window-system headers. Declare Vlibrary_cache when compiling for
5087 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
5088 window system declarations.
5090 * frame.h: Move common functions here: set_frame_menubar,
5091 x_set_window_size, x_sync, x_get_focus_frame,
5092 x_set_mouse_position, x_set_mouse_pixel_position,
5093 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5104 window-system headers.
5106 * emacs.c: Include TERM_HEADER.

5120 * lisp.h (mark_ttys): Remove prototype.
5121 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5122 to mark_ttys because all possible values of 'top_frame' slot are
5123 the frames which are reachable from Vframe_list.
5124 * term.c (mark_ttys): Remove.
5125 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5127 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5129 Change struct frame bitfields from unsigned char to unsigned.
5130 * frame.h (struct frame): Change type of 'display_preempted',

5144 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
5145 does not become zero (Bug#12234).
5147 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
5149 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
5150 for GCC 4.7.1 x86-64.
5152 2012-08-30 Glenn Morris <rgm@gnu.org>
5154 * lread.c (init_lread): For out-of-tree builds, only add the
5155 source directory's site-lisp dir to the load-path if it exists,
5156 consistent with in-tree builds. (Bug#12302)
5158 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5160 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

5162 (windowShouldClose:): Set window_closed.
5163 (dealloc): New member, free button_values.
5164 (process_dialog:): Make member function. Remove window argument,

5170 (addSplit): Remove return self, declare return value as void.
5171 (clicked:): Remove return self, declare return value as void.
5172 Set dialog_return to button_values[seltag]. Code formatting change.
5173 (initFromContents:isQuestion:): Adjust call to process_dialog.
5174 Code formatting change.
5175 (timeout_handler:): Set timer_fired to YES.
5176 (runDialogAt:): Set timer_fired to NO.
5177 Handle click on close button as quit.
5179 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5180 Add window_closed and button_values. Add void as return value for
5181 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5182 Add process_dialog as new member.
5184 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5186 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
5187 is not one of the heaps we manage. (Bug#12242)
5189 2012-08-28 Glenn Morris <rgm@gnu.org>
5191 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

5253 * dispextern.h (struct composition_it): Use bool for boolean.
5254 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
5255 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
5256 * dired.c (file_name_completion):
5257 Use bool for boolean. (This was missed in an earlier change.)
5259 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5261 * window.c (Fset_window_configuration): Revert first part of
5264 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
5266 * nsterm.h (NSPanel): New class variable dialog_return.

5322 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5323 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5324 not a boolean 'int', since callers never look at the return value.
5325 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5326 * coding.h (decoding_buffer_size, encoding_buffer_size)
5327 (emacs_mule_string_char): Remove unused extern decls.
5328 (struct iso_2022_spec, struct coding_system):

5344 buffer doesn't appear in the selected window, go to its old
5347 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5349 Special MEM_TYPE_SPARE to denote reserved memory.
5350 * alloc.c (enum mem_type): New memory type.
5351 (refill_memory_reserve): Use new type for spare memory.
5352 This prevents live_cons_p and live_string_p from incorrect

5362 * window.c (Qwindow_valid_p, decode_valid_window):
5363 Now static, not extern.
5364 * data.c (Qinterval): Remove; unused.

5381 (map_sub_char_table):
5382 Use bool for boolean.
5383 * character.c (str_to_unibyte): Omit last boolean argument; it was
5384 always 0. All callers changed.
5385 * character.h, charset.h: Adjust to match previous changes.
5386 * character.h (char_printable_p): Remove decl of nonexistent function.
5387 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5388 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5389 are all boolean, so make them single-bit bitfields.
5391 * lisp.h (ASET): Remove attempt to detect side effects.
5392 It was meant to be temporary and it often doesn't work,
5393 because when IDX has side effects the behavior of IDX==IDX
5394 is undefined. See Stefan Monnier in
5395 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5397 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5399 * lisp.h (functionp): New function (extracted from Ffunctionp).
5400 (FUNCTIONP): Use it.
5401 * eval.c (Ffunctionp): Use it.
5403 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5405 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5406 as that's faster and simpler than static storage. Don't bother
5407 with the g_main_context_query overhead if g_main_context_pending
5408 says no events are pending.
5409 (gfds, gfds_size): Remove these static vars.
5410 (xgselect_initialize): Remove; no longer needed.
5411 All uses and decls removed.
5413 * emacs.c (fatal_error_signal_hook): Remove.
5414 All uses removed. This leftover from old code was always 0.
5416 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5417 * casefiddle.c (casify_object, casify_region):
5418 * casetab.c (set_case_table):

5420 * category.h (CHAR_HAS_CATEGORY):
5421 Use bool for booleans, instead of int.
5423 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5425 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5427 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5429 On assertion failure, print backtrace if available.
5430 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5431 (die) [ENABLE_CHECKING]: Print a backtrace if available.

5440 * lisp.h (USE_SAFE_ALLOCA):
5441 Use bool for booleans, instead of int.
5442 * lisp.h, process.h: Adjust prototypes to match above changes.
5443 * callint.c (Fcall_interactively): Don't assume the mark's
5444 offset fits in 'int'.
5446 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5448 * buffer.c, buffer.h: Use bool for boolean.

5455 (mmap_enlarge, mmap_set_vars):
5456 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5457 Use bool for booleans, instead of int.
5458 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5459 since the 1-or-0 return value is always ignored anyway.
5460 (mmap_initialized_p):
5461 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5462 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5464 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5466 * bidi.c: Use bool for boolean.
5467 This is a bit more readable, and makes the text segment of bidi.o
5468 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5469 Presumably it's faster too.

5474 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5475 (bidi_explicit_dir_char, bidi_level_of_next_char)
5476 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5477 Use bool for booleans, instead of int.
5478 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5479 (bidi_unshelve_cache): Adjust decls to match code.
5481 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5483 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5486 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5488 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5489 * atimer.h: Include <stdbool.h>.
5491 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5493 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5494 compile time tests instead of run time tests on systems that do
5496 (FRAME_MAC_P): Remove leftover from deleted code.
5497 * frame.c (syms_of_frame): Remove leftover from deleted code.
5499 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5501 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5503 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5505 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5506 Otherwise, the compiler complains about (A?B:C) where B is void
5507 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5508 (fontset_add): Return void, for FONTSET_ADD.
5510 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5512 * alloc.c: Use bool for booleans.
5513 (gc_in_progress, abort_on_gc)
5514 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5515 (dont_register_blocks) [GC_MALLOC_CHECK]:
5516 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5517 (check_string_bytes, make_specified_string, memory_full)
5518 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5519 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5520 (mark_stack, valid_pointer_p, make_pure_string)
5521 (Fgarbage_collect, survives_gc_p, gc_sweep):
5522 Use bool for booleans, instead of int.
5523 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5524 Remove unused local.
5525 * alloc.c (PURE_POINTER_P):
5526 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5527 * editfns.c (Fformat):
5528 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5530 * fns.c (sweep_weak_table):
5531 * lisp.h (suppress_checking, push_message, survives_gc_p)
5532 (make_pure_string, gc_in_progress, abort_on_gc):
5533 * lread.c (readchar, read1):
5534 * print.c (Fprin1_to_string):
5535 * xdisp.c (push_message):
5536 Use bool for booleans affected directly or indirectly by
5539 Make recently-introduced setters macros.
5540 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5541 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5542 (set_fontset_default, set_fontset_fallback): Rename from their
5543 upper-case counterparts, and make them functions rather than macros.
5544 This is more consistent with the other recently-introduced setters.
5545 These don't need to be inline, since they're local.
5547 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5549 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5550 the loop (Bug#12247).
5552 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5554 * lisp.h (vcopy): Use memcpy rather than our own loop.
5555 This fixes a performance regression introduced by the recent
5556 addition of vcopy. This means 'vcopy' will need to be modified
5557 for a copying collector, but that's OK. Also, tighten the
5558 checking in the assertion.
5560 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5562 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5563 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5564 non-base glyph for the width of the base character, according to
5565 what x_draw_composite_glyph_string_foreground expects.
5566 Generate WADJUST value according to composition_gstring_width's
5567 expectations, to produce correct width of the composed character.
5568 Reverse the sign of the DU offset produced by ScriptPlace.
5570 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5572 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5574 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5576 Avoid direct writes to contents member of struct Lisp_Vector.
5577 * lisp.h (vcopy): New function to copy data into vector.
5578 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5579 * fns.c (Ffillarray): Use ASET.
5580 * keyboard.c (timer_check_2): Use AREF and ASET.
5581 (append_tool_bar_item, Frecent_keys): Use vcopy.
5582 * lread.c (read_vector): Use ASET.
5583 * msdos.c (Frecent_doskeys): Use vcopy.
5584 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5585 (Finternal_merge_in_global_face): Use ASET and vcopy.

5591 the position of its buffer's point.
5592 (Fset_window_point): For the selected window always go in its
5593 buffer to the specified position.
5595 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5597 Setter macros for fontsets.
5598 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5599 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5600 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5603 2012-08-20 Glenn Morris <rgm@gnu.org>
5605 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5606 Don't assume that `ln -f' works.
5608 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5610 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5611 and later about non-assignments with no effect. See discussion at
5612 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5615 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5617 Inline setter functions for Lisp_Objects slots of struct specbinding.
5618 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5621 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5623 * window.c (select_window): Always make selected window's buffer
5626 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5628 Use AREF and ASET for docstrings of category tables.
5629 * category.h (CATEGORY_DOCSTRING): Use AREF.
5630 (SET_CATEGORY_DOCSTRING): Use ASET.
5631 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5633 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5635 Inline setter functions for hash table members.
5636 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5637 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5638 (set_hash_key_and_value, set_hash_index, set_hash_next)
5639 (set_hash_hash): New functions.
5640 * charset.c, fns.c: Adjust users.
5642 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5644 Inline getter and setter functions for per-buffer values.
5645 * buffer.h (per_buffer_default, set_per_buffer_default)
5646 (per_buffer_value, set_per_buffer_value): New functions.
5647 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5648 * buffer.c, data.c: Adjust users.
5650 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5652 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5654 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5656 Rely on <config.h> + <unistd.h> to declare 'environ',
5657 as gnulib does this if the system doesn't.
5658 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5659 Remove declaration. MS-Windows declares it on stdlib.h which is
5660 included by conf_post.h.
5661 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5662 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5663 * vm-limit.c: Include <unistd.h>, for 'environ'.
5665 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5666 (start_of_data): Remove decl; mem-limits.h provides it.
5668 * xdisp.c (handle_invisible_prop): Make it a bit faster
5669 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5671 2012-08-19 Chong Yidong <cyd@gnu.org>
5673 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5676 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5678 * .gdbinit: Use call instead of set when calling a function in the
5681 * data.c (set_internal): Don't use set_blv_found.
5682 (Fkill_local_variable): Likewise.
5684 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5686 * nsfont.m (ns_ascii_average_width): Ensure the string
5687 ascii_printable is initialized with a null-terminated character
5688 array. Otherwise, it can contain undesired extra characters.
5690 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5692 port new setting code to Sun C 5.8 2005/10/13
5693 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5694 Return void, not Lisp_Object. Otherwise, the compiler
5695 complains about (A?B:C) where B is void and C is Lisp_Object
5696 when compiling CHAR_TABLE_SET, due to the recent change to
5697 the API of sub_char_table_set_contents.
5699 2012-08-18 Chong Yidong <cyd@gnu.org>
5701 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5702 for the string case (Bug#3874).

5857 The old version was confusing because it used the same name
5858 'parent' for two different things.
5860 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

5871 font spec, make the font's attributes take precedence over
5872 directly-specified attributes.
5873 (merge_face_ref): Recognize :font.
5875 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

6530 * w32.c (init_environment): Change the default values of many
6531 environment variables in dflt_envvars[] to NULL, to avoid pushing
6532 them into environment when they were not already defined.
6533 Remove the code that deletes site-lisp subdirectories from the default
6534 value of EMACSLOADPATH, as it is no longer needed.
6535 (check_windows_init_file): Now external, not static.
6536 Use Vload_path as is, without adding anything, as this function is now
6537 called when Vload_path is already set up.
6539 * w32.h (check_windows_init_file): Add prototype.
6541 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6573 (make_pure_float, make_pure_vector):
6574 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

6584 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6585 Remove unnecessary pointer casts.
6586 * alloc.c (record_xmalloc): New function.
6587 * lisp.h (record_xmalloc): New decl.
6588 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6589 more like a function. This is because the pointer cast is not
6590 needed. All uses changed.
6591 * print.c (print_string, print_error_message): Avoid length recalc.
6593 Improve fix for macroexp crash with debugging (Bug#12118).
6594 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6595 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6596 not supposed to be invoked from the garbage collector.
6597 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6598 (gc_aset): New function, which is like ASET but can be
6599 used in the garbage collector.
6600 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

6615 headers (most versions of MinGW w32api don't).
6616 (get_security_info, create_symbolic_link)
6617 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
6619 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
6620 in the argument file name.

6623 (sys_rename): Diagnose renaming of a symlink when the user doesn't
6624 have the required privileges.
6625 (get_file_security_desc_by_name): Rename from
6626 get_file_security_desc.

6628 with addition of handling of symlinks and support for 'lstat'.
6629 If possible, get file's attributes and security information by
6630 handle, not by name. Produce S_IFLNK bit for symlinks, when
6631 called from 'lstat'.
6632 (stat, lstat): New functions, call 'stat_worker'.
6633 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6634 symlinks when the underlying filesystem supports them.
6636 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6638 Fix macroexp crash on Windows with debugging (Bug#12118).
6639 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6640 checking subscripts; problem introduced with the recent
6641 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6642 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6643 since it's used in non-static inline functions now.
6645 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6646 Don't assume buffer size fits in 'int'. Remove unused local.

6667 * dispnew.c (DISPEXTERN_INLINE):
6668 * sysdep.c (SYSTIME_INLINE):
6669 Define to EXTERN_INLINE, so that the corresponding functions
6670 are compiled into code.
6671 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6672 (INLINE_HEADER_END): New macros.
6673 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6693 hard-coding the path separator.
6695 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6697 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6698 This how ASET and AREF are supposed to work, and makes
6699 it easier to think about future improvements. See
6700 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6701 * charset.h (set_charset_attr): New function.

7191 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from

7193 the fix for 12036 would have avoided some of the problems noted in
7194 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7195 would have been more obvious.
7196 * emacs.c: Do not include <verify.h>; no longer needed.

7205 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7206 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7207 not be usable in #if. This simplifies things.
7209 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7211 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7216 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7217 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7218 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7219 Adjust to changes in lisp.h and emacs.c, by using

7222 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7223 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7224 instead of gdb_valbits.

8132 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8133 * nsterm.m (ns_term_init):
8134 Avoid the need for strncpy, by using build_string or
8135 make_unibyte_string directly. Use dtoastr, not snprintf.
8136 * process.c (Fmake_network_process): Diagnose service names that
8137 are too long, rather than silently truncating them or creating
8138 non-null-terminated names.
8139 (Fnetwork_interface_info): Likewise, for interface names.
8140 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8141 Prefer sprintf to strncat.
8142 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

8154 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8155 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

8168 Optimize pure C strings initialization.
8169 * lisp.h (make_pure_string): Fix prototype.
8170 (build_pure_c_string): New function, defined as static inline. This
8171 provides a better opportunity to optimize away calls to strlen when
8172 the function is called with compile-time constant argument.
8173 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8174 argument, adjust users accordingly. Use build_pure_c_string where
8176 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8177 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8178 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8180 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8182 Avoid calls to strlen in miscellaneous functions.
8183 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8184 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8185 * lread.c (openp): Likewise.
8187 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8189 Avoid calls to strlen in path processing functions.
8190 * fileio.c (file_name_as_directory): Add comment. Change to add
8191 srclen argument and return the length of result. Adjust users
8193 (directory_file_name): Fix comment. Change to add srclen argument,
8194 swap 1st and 2nd arguments to obey the common convention.
8195 Adjust users accordingly.
8196 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8198 2012-07-10 Glenn Morris <rgm@gnu.org>
8200 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

8205 * s/gnu.h (DATA_START): Move definitions to configure.
8207 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8208 We include usg5-4-common.h, which defines them both.
8210 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8211 O_RDONLY already includes it).
8213 Stop ns builds setting the EMACSLOADPATH environment variable.
8214 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8215 Now it does not set EMACSLOADPATH, just returns the load-path string.
8216 * nsterm.h: Update accordingly.
8217 * lread.c [HAVE_NS]: Include nsterm.h.
8218 (init_lread) [HAVE_NS]: Use ns_load_path.

8221 2012-07-09 Glenn Morris <rgm@gnu.org>
8223 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8224 since the included bsd-common.h does so.
8226 Stop ns builds setting the EMACSPATH environment variable.
8227 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8228 (ns_init_paths): Do not set EMACSPATH.
8229 * nsterm.h (ns_exec_path): Add it.
8230 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8233 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8235 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8237 * process.c (wait_reading_process_output): 'waitchannels' was unset
8238 when read_kbd || !NILP (wait_for_cell); fix this.
8240 Add GCC-style 'const' attribute to functions that can use it.
8241 * character.h (char_resolve_modifier_mask):
8242 * keyboard.h (make_ctrl_char):
8243 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8250 Declare the dummy function with ATTRIBUTE_CONST.
8251 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8252 Add decls with ATTRIBUTE_CONST.
8254 Minor improvements to make_formatted_string.
8255 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8256 where int is good enough, as vsprintf returns an int.
8257 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8259 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8261 Use make_formatted_string to avoid double length calculation.
8262 * lisp.h (make_formatted_string): New prototype.
8263 * alloc.c (make_formatted_string): New function.
8264 * buffer.c (Fgenerate_new_buffer_name): Use it.
8265 * dbusbind.c (syms_of_dbusbind): Likewise.

8268 * frame.c (make_terminal_frame, set_term_frame_name)
8269 (x_report_frame_params): Likewise.
8270 * image.c (gs_load): Likewise.
8271 * minibuf.c (get_minibuffer): Likewise.

8286 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8288 Move marker debugging code under MARKER_DEBUG.
8289 * marker.c (MARKER_DEBUG): Move marker debugging code under
8290 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8291 for bootstrap with --enable-checking (~3x slowdown reported
8292 by Juanma Barranquero <lekktu@gmail.com>).
8293 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8295 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8297 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8298 See <http://bugs.gnu.org/11825#29>.
8300 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8302 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8303 has no font, use the frame's font. (Bug#11813)
8304 (display_line): Add commentary about displaying truncation glyphs
8306 (produce_special_glyphs): Move here from term.c.
8308 * term.c (produce_special_glyphs): Move to xdisp.c.
8310 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8313 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8315 * xdisp.c (display_line): Avoid warning about implicit declaration
8318 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8320 * lisp.h: Remove empty conditional.
8322 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8324 * lread.c (load_path_check): Now static.
8326 Fix some minor --with-ns problems found by static checking.
8327 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8328 (x_set_font) [!HAVE_X_WINDOWS]:
8329 * image.c (xpm_load_image) [HAVE_NS]:
8330 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8331 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8332 Remove unused local.
8333 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8334 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8335 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8336 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8337 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8338 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8339 Fix pointer signedness problem.
8340 * xfaces.c (FRAME_X_FONT_TABLE):
8341 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8343 2012-07-07 Glenn Morris <rgm@gnu.org>
8345 * lread.c (load_path_check): New function, split from init_lread.
8346 (init_lread): Reorganize. Motivation:
8347 If EMACSLOADPATH is set, check/warn about that rather than the
8348 defaults, which we are not going to use. Hence we can remove
8349 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8350 Don't warn if site-lisp directories are missing.
8351 If not installed, start from a blank load-path, since
8352 PATH_LOADSEARCH refers to the eventual installation directories.
8354 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8356 Support truncation and continuation glyphs on GUI frames, when
8357 fringes are disabled. (Bug#11832)
8358 * xdisp.c (init_iterator): Get dimensions of truncation and
8359 continuation glyphs even if on GUI frames.
8360 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8361 or both, are absent.
8362 (start_display, move_it_in_display_line_to): Handle the case of a
8363 GUI frame without a fringe to display continuation or truncation
8365 (insert_left_trunc_glyphs): Support GUI frames: make sure
8366 truncation glyphs overwrite enough glyphs from the current line to
8367 have sufficient space in pixels.
8368 (display_line): Support truncation and continuation glyphs on GUI
8369 frames. If some spare pixels are left on the line after inserting
8370 the truncation glyphs, fill that space with a stretch glyph of a
8371 suitably computed width.
8373 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8374 produce_glyphs, to support GUI sessions.
8376 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8378 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8380 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8382 Do not require float-time's arg to fit in time_t (Bug#11825).
8383 This works better on hosts where time_t is unsigned, and where
8384 float-time is applied to the (negative) difference between two times.
8385 * editfns.c (decode_time_components): Last arg is now double *,
8386 not int *, and means to store all the result as a double, without
8387 worrying about whether the seconds part fits in time_t.
8388 All callers changed.
8389 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8390 All callers changed.
8391 (Ffloat_time): Do not fail merely because the specified time falls
8392 outside of time_t range.
8394 2012-07-07 Glenn Morris <rgm@gnu.org>
8396 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8402 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8403 Update dependencies.
8405 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8407 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8409 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

8411 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8412 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8413 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8414 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8416 * xfont.c (compare_font_names): Redo to omit the need for casts.
8418 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8420 * xfns.c (Fx_change_window_property): Doc fix.
8421 * w32fns.c (Fx_change_window_property): Doc fix.
8423 * w32fns.c (Fx_window_property): Accept the same arguments as the
8424 X Windows version. Doc fix.
8425 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8427 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8428 Eli Zaretskii <eliz@gnu.org>
8430 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8431 Windows-specific code from nt/config.nt moved here.
8432 Obsolete settings removed.
8434 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8436 * process.c: Avoid unnecessary calls to gettime.
8437 (wait_reading_process_output): Don't get the time of day
8438 when gobbling data immediately and not waiting, as there's no need
8439 for it in that case. This removes a FIXME.
8441 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8443 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8444 is defined (Bug#11768).
8446 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8448 Fix marker debugging code.
8449 * marker.c (byte_char_debug_check): Do not perform the check
8450 if buffer is not multibyte.
8451 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8452 Call byte_char_debug_check with correct arguments.
8454 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8456 Compile marker debugging code only if ENABLE_CHECKING is defined.
8457 * marker.c (byte_char_debug_check, count_markers):
8458 Use only if ENABLE_CHECKING is defined.
8459 (byte_debug_flag): Remove.
8460 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8461 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8463 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8465 Avoid code repetition in marker-related functions.
8466 * marker.c (attach_marker): New function.
8467 (Fset_marker, set_marker_restricted, set_marker_both)
8468 (set_marker_restricted_both): Use it.
8469 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8470 Consistently rename charno to charpos.
8471 (marker_position): Add eassert.
8472 (marker_byte_position): Convert to eassert.

8491 * window.c (save_window_save): Likewise.
8493 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8495 Do not use Fdelete_overlay in delete_all_overlays
8496 to avoid redundant calls to unchain_overlay.
8497 * buffer.c (drop_overlay): New function.
8498 (delete_all_overlays, Fdelete_overlay): Use it.
8499 * minibuf.c (get_minibuffer): Fix comment.
8501 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8503 Port to OpenBSD 5.1 amd64.
8504 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8505 This is needed for OpenBSD, and should be harmless on all BSD systems.
8506 Also, include <sys/sysctl.h>, as it should be available on all
8507 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8508 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8509 use p_pid member, not kp_proc.pid.
8511 2012-07-06 Glenn Morris <rgm@gnu.org>
8513 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8515 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8517 More xmalloc and related cleanup.
8518 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8519 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
8520 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
8521 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
8522 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:

8526 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8528 Omit needless casts involving void * pointers and allocation.
8529 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8530 as the former is more robust if P's type is changed.
8531 Prefer xzalloc to xmalloc + memset 0.
8532 Simplify malloc-or-realloc to realloc.
8533 Don't worry about xmalloc returning a null pointer.
8534 Prefer xstrdup to xmalloc + strcpy.
8535 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8537 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8538 alloca of a constant.
8540 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8542 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8543 hscroll is larger than the line width. Fixes long and futile
8544 looping inside extend_face_to_end_of_line (on a TTY) producing
8545 glyphs that are not needed and thrown away.
8547 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8549 * marker.c (set_marker_restricted_both): Simplify by using
8552 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

8575 * xdisp.c (window_hscroll_limited): New function.
8576 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8577 coordinates when window's hscroll is set to insanely large
8580 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8582 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8583 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
8585 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8588 * lisp.h (xzalloc): New prototype. Omit needless casts.

8643 * fileio.c (time_error_value): Check the right error number.
8644 Problem reported by Troels Nielsen in
8645 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8647 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8649 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8650 This should be fixed in a better way; see Eli Zaretskii in
8651 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8652 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8654 * fileio.c (time_error_value): Rename from special_mtime.
8655 The old name's problems were noted by Eli Zaretskii in
8656 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8658 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8659 This variable's comment says Emacs needs at least one GDB-visible
8660 symbol of type enum pvec_type, to work around GDB problems.
8661 The symbol's value doesn't matter.
8663 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8664 that causes compilation to fail on pre-C99 compilers.
8666 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8668 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8669 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8671 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8673 * buffer.c (init_buffer_once): Fix initialization of
8674 headers for buffer_defaults and buffer_local_symbols.
8675 Reported by Juanma Barranquero <lekktu@gmail.com>.
8677 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8679 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8680 * lisp.h (enum pvec_type): Use fewer bits.
8681 (PSEUDOVECTOR_SIZE_BITS): New constant.
8682 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8683 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8684 change in pvec_type.
8685 (PSEUDOVECTOR_TYPEP): New macro.
8686 (TYPED_PSEUDOVECTORP): Use it.
8687 * fns.c (internal_equal): Adapt code to extract pvectype.

8689 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8690 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8691 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8692 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8693 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8694 abusing vector->header.next.nbytes.
8695 (live_vector_p): Use PVEC_TYPE.
8696 (mark_object): Adapt code to extract pvectype. Use switch.
8698 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8700 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8701 Tighten new eassert a bit.
8703 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8705 Fix compilation with --enable-gcc-warnings and -O1
8707 * doprnt.c (doprnt): Change type of tem to int, initialize
8708 to avoid compiler warning. Add eassert.
8709 * search.c (simple_search): Initialize match_byte to avoid
8710 compiler warning. Add eassert.
8712 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8714 Avoid weird behavior with large horizontal scrolls.
8715 Without this change, for example, large hscroll values would
8716 mess up Emacs's display on Fedora 15 x86, presumably due to
8717 overflows in int calculations in the display code.
8718 Also, if buffers had long lines, Emacs would freeze.
8719 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8720 (set_window_hscroll): New function, containing the old guts of
8721 Fset_window_hscroll. Return the clipped value.
8722 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8723 This avoids the need to check against PTRDIFF_MAX.
8725 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8727 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8729 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8731 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8733 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8734 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8735 since GCC 4.4.6 issues a bogus warning for them.
8737 Fix bugs in file timestamp newness comparisons.
8738 * fileio.c (Ffile_newer_than_file_p):
8739 * lread.c (Fload): Use full timestamp resolution of files,
8740 not just the 1-second resolution, so that files that are only
8741 slightly newer still count as newer.
8742 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8743 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8745 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8747 * fileio.c: Improve handling of file time marker. (Bug#11852)
8748 (special_mtime): New function.
8749 (Finsert_file_contents, Fverify_visited_file_modtime):
8750 Use it to set special mtime values consistently.
8752 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8754 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8755 marker for non-existing file. (Bug#11852)
8757 2012-07-03 Glenn Morris <rgm@gnu.org>
8759 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8760 and did not make it into globals.h).
8762 2012-07-03 Tom Tromey <tromey@redhat.com>
8764 * window.c (Fset_window_margins, Fset_window_fringes)
8765 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8766 * textprop.c (Fprevious_property_change): No longer static.
8767 * syntax.c (Fsyntax_table_p): No longer static.

8789 * intervals.h: Remove EXFUNs.
8790 * fontset.h: Remove EXFUN.

8796 * window.h: Remove EXFUNs.

8798 * xterm.h: Remove EXFUN.
8800 2012-07-03 Glenn Morris <rgm@gnu.org>
8802 * lisp.h (Frandom): Make it visible to C.
8803 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8804 buffer for invisible buffers. (Bug#1229)
8806 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8808 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8809 values which aren't power of 2.
8810 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8811 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8814 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8816 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8818 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8820 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8822 * alloc.c (allocate_vector_block): Remove redundant
8823 calls to mallopt if DOUG_LEA_MALLOC is defined.
8824 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8825 avoid calls to mallopt if zero_vector is returned.
8827 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8829 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8830 is enabled, avoid dereferencing NULL current_sblock if
8833 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8835 Cleanup basic buffer management.
8836 * buffer.h (struct buffer): Change layout to use generic vector
8837 marking code. Fix some comments. Change type of 'clip_changed'
8838 to bitfield. Remove unused #ifndef old.
8839 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8840 (GET_OVERLAYS_AT): Fix indentation.
8841 (for_each_per_buffer_object_at): New macro.

8845 * alloc.c (allocate_buffer): Adjust to match new layout of
8846 struct buffer. Fix comment.
8847 (mark_overlay): New function.

8850 (mark_object): Use it. Adjust marking of misc objects
8851 and related comments.
8853 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8855 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8856 wrapper that is not needed because the wrapped code is a no-op (zero
8857 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8858 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8860 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8862 * alloc.c (mark_buffer): Simplify. Remove prototype.
8863 (mark_object): Add comment. Reorganize marking of vector-like
8864 objects. Use CHECK_LIVE for all vector-like objects except buffers
8865 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8866 Avoid redundant calls to mark_vectorlike for bool vectors.
8868 2012-06-30 Glenn Morris <rgm@gnu.org>
8870 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8872 * epaths.in (PATH_SITELOADSEARCH): New.
8873 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8874 This is rather than relying on --enable-locallisppath elements
8875 having "site-lisp" in their names. (Bug#10208#25, 11658)
8877 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8879 * w32proc.c (sys_select): Accept and ignore one more argument.
8881 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8883 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8884 (pselect) [!MS_DOS]: Redirect to sys_select.
8886 * sysdep.c: Don't include dos.h and dosfns.h.
8888 * process.c (sys_select):
8889 * msdos.c (sys_select): Accept one more argument and ignore it.
8891 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8892 adapt data types and code to that.
8895 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8896 which clashes with the gnulib function of the same name.
8898 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8900 * font.c (font_style_to_value, font_style_symbolic)
8901 (font_prop_validate_style): Add type checks for values in
8904 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8906 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8909 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8911 * xdisp.c (try_window_id): Undo last change.
8913 * w32.c (getwd): Adjust commentary about startup_dir.
8914 (init_environment): Always call sys_access, even in non-MSVC
8915 builds. Don't chdir to the directory of the Emacs executable.
8916 This undoes code from 1997 which was justified by the need to
8917 "avoid conflicts when removing and renaming directories". But its
8918 downside was that every relative file name was being interpreted
8919 relative to the directory of the Emacs executable, which can never
8920 be TRT. In particular, it broke sys_access when called with
8921 relative file names.
8922 (sys_access): Map GetLastError to errno.
8924 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8926 * window.h (struct window): Change type of 'fringes_outside_margins'

8930 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8933 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8935 * gnutls.c (emacs_gnutls_handshake):
8936 Add QUIT to make the loop interruptible.
8938 2012-06-29 Glenn Morris <rgm@gnu.org>
8940 * charset.c (init_charset): Make lack of etc/charsets fatal.
8942 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8944 * editfns.c (region_limit): Fix type mismatch.
8946 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8948 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8949 undefined. Convert from xassert to eassert.
8950 * nsmenu.m: Convert from xassert to eassert.
8951 * nsterm.m: Likewise.
8953 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8955 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8957 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8959 Avoid integer overflow on scroll-left and scroll-right.
8960 * window.c (HSCROLL_MAX): New macro.
8961 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8962 overflow when requested scroll falls outside ptrdiff_t range.
8964 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8966 * window.h (struct window): Change type of 'hscroll',
8967 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8968 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8969 Adjust users accordingly.
8970 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8971 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8972 from EMACS_INT to ptrdiff_t.
8973 (make_window): Omit redundant initialization.
8975 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8977 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8979 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8981 * window.h (struct window): Change type of 'use_time' and
8982 'sequence_number' from Lisp_Object to int.

8991 enabled with --enable-checking=[all,glyphs] configure option.
8992 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8993 adjust comments accordingly.

9044 avoid GCC warning about unused macro.
9046 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9048 * alloc.c (allocate_string): Omit intervals initialization.
9049 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9050 as in make_pure_string and make_pure_c_string.
9052 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9054 * alloc.c (allocate_string): Fix last change.
9056 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9108 a better opportunity to optimize away calls to strlen when the
9109 function is called with compile-time constant argument.
9110 * image.c (imagemagick_error): Convert to build_string.
9111 * w32proc.c (sys_spawnve): Likewise.
9112 * xterm.c (x_term_init): Likewise.
9114 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9116 Use sprintf return value instead of invoking strlen on result.
9117 In the old days this wasn't portable, since some sprintf
9118 implementations returned char *. But they died out years ago and
9119 Emacs already assumes sprintf returns int.
9120 Similarly for float_to_string.
9121 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9122 * ccl.c (ccl_driver):
9123 * character.c (string_escape_byte8):

9126 * print.c (print_object):
9127 * xdisp.c (message_dolog):
9128 * xfns.c (syms_of_xfns):
9129 Use sprintf or float_to_string result to avoid need to call strlen.
9130 * data.c (Fnumber_to_string):
9131 Use make_unibyte_string, since the string must be ASCII.
9132 * lisp.h, print.c (float_to_string): Now returns int length.
9133 * term.c (produce_glyphless_glyph):
9134 Use sprintf result rather than recomputing it.
9136 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9137 * Makefile.in (ALL_CFLAGS):
9138 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9139 * gmalloc.c, regex.c: Include <config.h> unconditionally.
9141 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9143 * dispextern.h (xstrcasecmp): Define to library function
9144 strcasecmp if available.
9145 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

9160 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9162 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9163 sprintf already null-terminates its output.
9165 * xfns.c (x_window): Remove redundant cast.
9167 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9169 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9170 `const char *' to `char *' to avoid compiler warning.
9172 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9174 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9175 instead of truncating it to 63 (admittedly a generous limit).
9177 * process.c: Fix spelling and caps in comments.
9179 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9181 * emacs.c (setpgrp): Remove definition, unused.

9228 Remove unnecessary forward decls.
9230 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9232 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

9234 * dispnew.c (Fsleep_for, sit_for):
9235 * keyboard.c (kbd_buffer_get_event):
9236 * process.c (Faccept_process_output):
9237 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9238 This improves on the previous patch, which introduced a bug
9239 when time_t is unsigned and as wide as intmax_t.
9240 See <http://bugs.gnu.org/9000#51>.
9242 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9244 * dispnew.c (sit_for, Fsleep_for):
9245 * keyboard.c (kbd_buffer_get_event):

9258 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9259 Privately reported by Herbert J. Skuhra.
9260 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9262 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9263 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9265 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9267 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9268 last argument of make_unibyte_string.
9270 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9271 language ID in the event parameters.
9273 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9274 event.code, not the obscure "character set ID".
9276 2012-06-23 Chong Yidong <cyd@gnu.org>
9278 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

9297 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9298 Privately reported by Herbert J. Skuhra.
9299 [__FreeBSD__]: Remove "*/" typo after "#include".

9305 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9307 Support higher-resolution time stamps (Bug#9000).
9308 The time stamps are only nanosecond-resolution at the C level,
9309 since that's the best that any real-world system supports now.
9310 But they are picosecond-resolution at the Lisp level, as that's
9311 easy, and leaves room for future OS improvements.
9313 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9316 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9317 Don't get current time unless it's needed.
9319 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9320 now provides it if it's absent.
9321 (start_atimer): Port to higher-res time stamps.
9322 Check for time stamp overflow. Don't get current time more
9323 often than is needed.
9325 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9326 Include systime.h, not time.h.
9327 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9329 * dired.c: Include stat-time.h.
9330 (Ffile-attributes): File times now have higher resolution.
9332 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9333 (struct image): Timestamp now has higher resolution.
9335 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9336 has at least microseconds now. All uses removed.
9337 (update_frame, update_single_window, update_window, update_frame_1)
9338 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9339 (duration_to_sec_usec): Remove; no longer needed.
9341 * editfns.c (time_overflow): Now extern.
9342 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9343 (float-time, Fformat_time_string, Fcurrent_time_string)

9346 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9347 (decode_time_components, lisp_seconds_argument): New functions.
9348 (make_time): Now static.
9349 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9350 Report an error if the time is invalid, rather than having the caller
9353 * fileio.c: Include <stat-time.h>
9354 (Fcopy_file): Copy higher-resolution time stamps.
9355 Prefer to set the time stamp via a file descriptor if that works.
9356 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9357 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9358 (Fvisited_file_modtime, Fset_visited_file_modtime):
9359 Support higher-resolution time stamps.
9361 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9363 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9365 * image.c (prepare_image_for_display, clear_image_cache)
9366 (lookup_image): Port to higer-resolution time stamps.
9368 * keyboard.c (start_polling, bind_polling_period):
9369 Check for time stamp overflow.
9370 (read_char, kbd_buffer_get_event, timer_start_idle)
9371 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9372 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9373 Port to higher-resolution time stamps. Do not assume time_t is signed.
9374 (decode_timer): New function. Timers are now vectors of length 9,
9375 not 8, to accommodate the picosecond component.
9376 (timer_check_2): Use it.
9378 * nsterm.m (select_timeout, timeval_subtract): Remove.
9379 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9380 as they're a bit more accurate and handle overflow better.
9381 (ns_select): Change prototype to be compatible with pselect.
9382 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9383 * nsterm.h (ns_select): Adjust prototype.
9385 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9386 us-resolution time stamps.
9387 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9389 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9391 * lisp.h (time_overflow): New decl.
9392 (wait_reading_process_output): First arg is now intmax_t, not int,
9393 to accommodate larger waits.
9395 * process.h (struct Lisp_Process.read_output_delay):
9396 Now counts nanoseconds, not microseconds.
9397 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9399 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9400 (wait_reading_process_output):
9401 Port to ns-resolution time stamps.
9402 (Faccept_process_output, wait_reading_process_output):
9403 Check for time stamp overflow. Do not assume time_t is signed.
9404 (select_wrapper): Remove; we now use pselect.
9405 (Fprocess_attributes): Now generates ns-resolution time stamps.
9407 * sysdep.c: Include utimens.h. Don't include utime.h
9408 or worry about struct utimbuf; gnulib does that for us now.
9409 (gettimeofday): Remove; gnulib provides a substitute.
9410 (make_timeval): New function.
9411 (set_file_times): Now sets ns-resolution time stamps.
9412 New arg FD; all uses changed.
9413 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9414 (system_process_attributes):
9415 Now returns ns-resolution time stamp. All uses changed.
9416 Check for time stamp overflow.
9418 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9419 provides a substitute now.
9421 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9422 since it guarantees struct timespec.
9423 (EMACS_TIME): Now struct timespec, so that we can support
9424 ns-resolution time stamps.
9425 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9426 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9427 (EMACS_USECS): Remove.
9428 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9429 so multiply the arg by 1000 before storing it.
9430 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9432 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9433 Port to ns-resolution time stamps.
9434 (EMACS_TIME_NEG_P): Remove; replaced by....
9435 (EMACS_TIME_SIGN): New macro.
9436 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9437 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

9439 (make_timeval, make_lisp_time, decode_time_components): New decls.
9440 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9441 that it mishandled time_t overflow. You can't compare by subtracting!
9442 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9443 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9445 * term.c: Include <sys/time.h>.
9446 (timeval_to_Time): New function, for proper overflow wraparound.

9451 (Fprimitive_undo): Use them when restoring time stamps.
9453 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9454 (w32_get_internal_run_time):
9455 Port to higher-resolution Emacs time stamps.
9456 (ltime): Now accepts single 64-bit integer, as that's more convenient
9459 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9461 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9462 for compatibility with pselect. Support ns-resolution time stamps.
9464 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9466 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9467 Check for time stamp overflow, and support ns-resolution time stamps.
9469 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9470 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9471 (timeval_subtract): Remove; no longer needed.
9472 (XTflash, XTring_bell, x_wait_for_event):
9473 Port to ns-resolution time stamps. Don't assume time_t is signed.
9475 2012-06-22 Chong Yidong <cyd@gnu.org>
9477 * xdisp.c (x_consider_frame_title): Revert last change.
9479 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9481 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9482 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9483 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9484 staticidx goes up to 1597 out of 1600 = 0x640.)
9486 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9488 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9489 Otherwise, the umask might be mistakenly 0 while handling input signals.
9491 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9493 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9499 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9500 access to `contents' member of Lisp_Vector objects with AREF and ASET
9503 2012-06-19 Chong Yidong <cyd@gnu.org>

9509 frame's selected window and its terminal's top-frame.
9510 (unwind_format_mode_line): Restore them.
9511 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9513 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9514 since tty frames can be explicitly named.
9515 (prepare_menu_bars): Likewise.
9517 * term.c (Ftty_top_frame): New function.
9519 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9521 Port byte-code-meter to modern targets.
9522 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9523 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9524 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9525 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9526 (METER_1, METER_2): Simplify.
9528 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
9530 * data.c (Fdefalias): Return `symbol' (bug#11686).
9532 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9534 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9535 gets killed during executing of this function (Bug#11665).

9758 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9759 Use an inline function on all platforms when using the union type,
9760 since this is simpler and 'static inline' can be used portably

9904 * doprnt.c (doprnt): Truncate multibyte char correctly.
9905 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9906 would mishandle a string argument "Xc" if X was a multibyte

9982 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9983 fields from Lisp_Object to bitfield. Adjust users accordingly.

9991 and 'double' in a couple of places.
9993 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9995 * xdisp.c (handle_stop): Detect whether we have overlay strings
9996 loaded by testing it->current.overlay_string_index to be
9997 non-negative, instead of checking whether n_overlay_strings is
9998 positive. (Bug#11587)

10015 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10016 for the duration of call to load_charset, to avoid problems with
10017 callers of maybe_unify_char that access buffer text through C
10020 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10021 decrement the inhibition flag, instead of just setting or
10024 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10026 Remove obsolete '#define static' cruft.
10027 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10028 This #undef was "temporary" in 2000; it is no longer needed
10029 now that '#define static' has gone away.
10030 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10031 (gray_bitmap_bits): Remove; no longer needed.
10032 All uses replaced with definiens.
10033 * xterm.c: Include "bitmaps/gray.xbm".
10035 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10037 Clean up __executable_start, monstartup when --enable-profiling.
10038 The following changes affect the code only when profiling.
10039 * dispnew.c (__executable_start): Rename from safe_bcopy.
10040 Define only on platforms that need it.
10041 * emacs.c: Include <sys/gmon.h> when profiling.
10042 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10043 (__executable_start): Remove decl, since lisp.h does it now.
10044 (safe_bcopy): Remove decl; no longer has that name.
10045 (main): Coalesce #if into single bit of code, for simplicity.
10046 Cast pointers to uintptr_t, since standard libraries want integers
10048 * lisp.h (__executable_start): New decl.
10050 2012-05-31 Glenn Morris <rgm@gnu.org>
10052 * image.c (Fimagemagick_types): Doc fix.
10054 2012-05-30 Jim Meyering <meyering@redhat.com>
10056 * callproc.c (Fcall_process_region): Include directory component
10057 in mkstemp error message (Bug#11586).
10059 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10061 * alloc.c, lisp.h (make_pure_vector): Now static.
10063 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10065 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10066 Move to byte-run.el.

10069 (Qdefun): Move from eval.c.
10070 * lisp.h (Qdefun): Remove.
10071 * lread.c (read1): Tiny simplification.
10073 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10075 Do not create empty overlays with the evaporate property (Bug#9642).
10076 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10077 Bug#9642, but explicitly check that the buffer the overlay would
10078 be moved to is live and rearrange lines to make sure that errors
10079 will not put the overlay in an inconsistent state.
10080 (Fdelete_overlay): Cosmetics.
10082 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10084 * w32term.c (my_bring_window_to_top): New function.
10085 (x_raise_frame): Use handle returned by DeferWindowPos, which
10086 could be different from the original one.

10096 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10098 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10099 This avoids undefined behavior that might cause the eassert
10100 to not catch an out-of-range value.
10102 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10104 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10105 Update dependencies.
10107 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10109 * bidi.c (bidi_mirror_char): Fix last change.
10111 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

10114 when referring to sectname field in printf format.
10116 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10118 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10119 Only r_alloc_inhibit_buffer_relocation needed to be added;
10120 the others were already declared.
10122 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10123 before checking whether it's out of range. Put the check inside
10125 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10127 2012-05-27 Ken Brown <kbrown@cornell.edu>
10129 * callproc.c (Fcall_process): Restore a line that was accidentally
10130 commented out in the 2011-02-13 change (bug#11547).
10132 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10134 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10135 defined on ralloc.c.
10137 * buffer.c [REL_ALLOC]: Remove prototypes of
10138 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10139 they are now on lisp.h.
10141 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10143 * search.c (search_buffer): Use it to inhibit relocation of buffer
10144 text while re_search_2 is doing its job, because re_search_2 is
10145 passed C pointers to buffer text. (Bug#11519)
10147 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10148 Update value to 24.
10150 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10151 state after an additional call to move_it_in_display_line_to, keep
10152 the values of it->max_ascent and it->max_descent found for the
10154 (pos_visible_p): Revert the comparison against bottom_y to what it
10155 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10158 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10160 Fix coding-related core dumps with gcc -ftrapv.
10161 The code was computing A - B, where A and B are pointers, and B is
10162 random garbage. This can lead to core dumps on platforms that
10163 have special pointer registers, and it also leads to core dumps on
10164 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10165 A - B only when B is initialized properly.
10166 * coding.c (coding_set_source, coding_set_destination): Return void.
10167 (coding_change_source, coding_change_destinations): New functions,
10168 with the old behaviors of coding_set_source and coding_set_destination.
10169 All callers that need an offset changed to use these new functions.
10171 2012-05-26 Glenn Morris <rgm@gnu.org>
10173 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10175 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10177 Extend mouse support on W32 text-mode console.
10178 * xdisp.c (draw_row_with_mouse_face):
10179 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10181 * w32console.c: Include window.h.
10182 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10184 (initialize_w32_display): Initialize mouse-highlight data.
10186 * w32inevt.c: Include termchar.h and window.h.
10187 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10188 moves, call note_mouse_highlight. If help_echo changed, call
10189 gen_help_event to produce help-echo message in the echo area.
10190 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10193 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10195 * lread.c (read1): Simplify slightly to avoid an overflow warning
10196 with GCC 4.7.0 on x86-64.
10198 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10200 * bidi.c (bidi_mirror_char): Revert last change: an int is
10201 definitely wide enough here.
10203 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10205 Fix integer width and related bugs (Bug#9874).
10206 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
10207 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
10208 (string_bytes, check_sblock, allocate_string_data):
10209 (compact_small_strings, Fmake_bool_vector, make_string)
10210 (make_unibyte_string, make_multibyte_string)
10211 (make_string_from_bytes, make_specified_string)
10212 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10213 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10215 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10216 (allocate_pseudovector):
10217 Use int, not EMACS_INT, where int is wide enough.
10218 (inhibit_garbage_collection, Fgarbage_collect):
10219 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10220 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10221 int might not be wide enough.
10222 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10223 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10224 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10225 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10226 (bidi_level_of_next_char, bidi_move_to_visually_next):
10227 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10228 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10229 (Fkill_buffer, Fset_buffer_major_mode)
10230 (advance_to_char_boundary, Fbuffer_swap_text)
10231 (Fset_buffer_multibyte, overlays_at, overlays_in)
10232 (overlay_touches_p, struct sortvec, record_overlay_string)
10233 (overlay_strings, recenter_overlay_lists)
10234 (adjust_overlays_for_insert, adjust_overlays_for_delete)
10235 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
10236 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
10237 (Foverlay_recenter, last_overlay_modification_hooks_used)
10238 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10239 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10240 (validate_region): Omit unnecessary test for b <= e,
10241 since that's guaranteed by the previous test.
10242 (adjust_overlays_for_delete): Avoid pos + length overflow.
10243 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10244 (report_overlay_modification):
10245 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10246 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10247 Omit pointer cast, which isn't needed anyway, and doesn't work
10248 after the EMACS_INT -> ptrdiff_t change.
10249 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10250 * buffer.h: Adjust decls to match defn changes elsewhere.
10251 (struct buffer_text, struct buffer):
10252 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10253 Use EMACS_INT, not int, where int might not be wide enough.
10254 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10255 not int, to avoid needless 32-bit limit on 64-bit hosts.
10256 (exec_byte_code): Use tighter memory-full test, one that checks
10257 for alloca overflow. Don't compute the address of the object just
10258 before an array, as that's not portable. Use EMACS_INT, not
10259 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10260 * callint.c (Fcall_interactively):
10261 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10262 * callproc.c (call_process_kill, Fcall_process):
10263 Don't assume pid_t fits into an Emacs fixnum.
10264 (call_process_cleanup, Fcall_process, child_setup):

10268 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10269 (Fcall_process): Simplify handling of volatile integers.

10271 * casefiddle.c (casify_object, casify_region, operate_on_word)
10272 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10273 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10274 (casify_object): Avoid integer overflow when overallocating buffer.
10275 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10276 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10277 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10278 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10279 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10280 integers are now checked earlier. All uses replaced with XINT.
10282 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10283 For CCL_MapSingle, check that content and value are in int range.
10284 (ccl_driver, Fregister_code_conversion_map):
10285 Check that Vcode_version_map_vector is a vector.
10286 (resolve_symbol_ccl_program): Check that vector header is in range.
10287 Always copy the vector, so that we can check its contents reliably
10288 now rather than having to recheck each instruction as it's being
10289 executed. Check that vector words fit in 'int'.
10290 (ccl_get_compiled_code, Fregister_ccl_program)
10291 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10292 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10293 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10294 contents are in range.
10295 (Fccl_execute_on_string): Check that status is in range.
10296 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10297 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10298 Accept and return EMACS_INT, not int, because callers can pass values
10299 out of 'int' range.
10300 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10301 (multibyte_chars_in_text, parse_str_as_multibyte)

10304 (string_escape_byte8, Fget_byte):
10305 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10306 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10307 avoid mishandling large integers.
10308 * character.h: Adjust decls to match defn changes elsewhere.
10309 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10310 (Ffind_charset_region):
10311 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

10313 (load_charset_map_from_vector, Fdefine_charset_internal):
10314 Don't assume fixnum fits in int.
10315 (load_charset_map_from_vector, Fmap_charset_chars):
10316 Remove now-unnecessary CHECK_NATNUMs.
10317 (Fdefine_charset_internal): Check ranges here, more carefully.
10318 Don't rely on undefined behavior with signed left shift overflow.
10319 Don't assume unsigned int fits into fixnum, or that fixnum fits
10320 into unsigned int. Don't require max_code to be a valid fixnum;
10321 that's not true for gb10830 4-byte on a 32-bit host. Allow
10322 invalid_code to be a cons, for the same reason. Require code_offset
10323 to be a character. Avoid int overflow if max_char is close
10325 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10326 this is intended anyway and avoids some undefined behavior.
10327 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10328 INDEX_TO_CODE_POINT, as that's what it expects.
10329 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10330 * charset.h (DECODE_CHAR): Return int, not unsigned;
10331 this is what was intended anyway, and it avoids undefined behavior.
10332 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10333 integer-overflow issues.
10334 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10335 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10336 where the argument is EMACS_INT, and this behavior is not intended.
10337 * chartab.c (Fmake_char_table, Fset_char_table_range)
10338 (uniprop_get_decoder, uniprop_get_encoder):
10339 Don't assume fixnum fits in int.
10340 * cmds.c (move_point): New function, that does the gist of
10341 Fforward_char and Fbackward_char, but does so while checking
10342 for integer overflow more accurately.
10343 (Fforward_char, Fbackward_char): Use it.
10344 (Fforward_line, Fend_of_line, internal_self_insert)
10345 (internal_self_insert):
10346 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10347 Fix a FIXME, by checking for integer overflow when calculating
10348 target_clm and actual_clm.

10380 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10381 (consume_chars): Rewrite to not calculate an address outside buffer.
10382 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10383 Don't access memory outside of the args array.
10384 (Fdefine_coding_system_internal): Check for charset-id overflow.
10385 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10386 result of ENCODE_CHAR.
10387 * coding.h: Adjust decls to match defn changes elsewhere.
10388 (struct coding_system):

11089 * xterm.h (x_in_use): Declare.
11090 * xgselect.c: Include xterm.h.
11091 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11092 and `display_arg' (bug#9754).
11094 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11096 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11098 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11099 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11101 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11103 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11105 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11106 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11108 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11109 reference to image_cache->refcount.
11110 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11112 2012-05-17 Juri Linkov <juri@jurta.org>
11114 * search.c (Fword_search_regexp, Fword_search_backward)
11115 (Fword_search_forward, Fword_search_backward_lax)
11116 (Fword_search_forward_lax): Move functions to isearch.el
11117 (bug#10145, bug#11381).
11119 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11121 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11123 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11125 * lread.c (init_obarray): Declare Qt and Qnil as special.
11127 2012-05-14 Glenn Morris <rgm@gnu.org>
11129 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11130 Put "libexec" before "bin", for the sake of init_callproc_1.
11132 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11134 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11136 * unexaix.c: Port to more-recent AIX compilers.
11137 (report_error, report_error_1, make_hdr, copy_sym)
11138 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11139 Make arguments const char *, not char *, to avoid violations of C
11140 standard and to fix some AIX warnings reported by Gilles Pion.
11142 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11144 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11145 already have overlays loaded.
11146 (handle_single_display_spec): Before returning without displaying
11147 fringe bitmap, synchronize the bidi iterator with the main display
11148 iterator, by calling iterate_out_of_display_property.
11149 (iterate_out_of_display_property): Detect buffer iteration by
11150 testing that it->string is a Lisp string.
11151 (get_next_display_element): When the current object is exhausted,
11152 and there's something on it->stack, call set_iterator_to_next to
11153 proceed with what's on the stack, instead of returning zero.
11154 (set_iterator_to_next): If called at the end of a Lisp string,
11155 proceed to consider_string_end without incrementing string
11156 position. Don't increment display vector index past the end of
11157 the display vector. (Bug#11417)
11158 (pos_visible_p): Don't report a position visible when move_it_to
11159 stopped at the last line of window, which happens to be scanned
11160 backwards by the bidi iteration. (Bug#11464)
11162 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11164 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11165 and right-margin display specs even if the spec is invalid or we
11166 are on a TTY, and thus unable to display on the fringes.
11167 That's because the text with the property will not be displayed anyway,
11168 so we need to signal to the caller that this is a "replacing"
11169 display spec. This fixes display when the spec is invalid or we
11172 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11174 * unexaix.c (make_hdr): Fix typo in prototype.
11175 This bug broke the build on AIX. Problem reported by Gilles Pion.
11177 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11179 * keyboard.c (kbd_buffer_get_event): Read special events also in
11180 batch mode. (Bug#11415)
11182 2012-05-12 Glenn Morris <rgm@gnu.org>
11184 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11186 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11188 * lisp.mk (lisp): Add newcomment.elc.
11190 2012-05-12 Glenn Morris <rgm@gnu.org>
11192 * Makefile.in (MKDIR_P): New, set by configure.
11193 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11195 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11197 Remove unused function hourglass_started.
11198 * dispextern.h (hourglass_started):
11199 * w32fns.c (hourglass_started):
11200 * xdisp.c (hourglass_started): Remove.
11202 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11204 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11205 Update dependencies.
11207 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11209 * xgselect.c (xg_select): Put maxfds+1 into a var.
11210 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11212 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11214 2012-05-10 Dave Abrahams <dave@boostpro.com>
11216 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11217 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11219 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11221 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11222 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11223 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11224 Initialize xd_registered_buses.
11226 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11228 Untag more efficiently if USE_LSB_TAG.
11229 This is based on a proposal by YAMAMOTO Mitsuharu in
11230 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11231 For an admittedly artificial (nth 8000 longlist) benchmark on
11232 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11233 Emacs's overall text size by 1%.
11234 * lisp.h (XUNTAG): New macro.
11235 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11236 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11237 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11238 * eval.c (Fautoload):
11239 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11240 * frame.h (XFRAME): Use XUNTAG.
11242 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11243 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11244 Remove unportable assumptions about print widths of types like
11246 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11247 intptr_t when converting between pointer and integer, to avoid GCC
11248 warnings about wrong width.
11250 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11252 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11253 stack for each reader_thread, instead of defaulting to 8MB
11254 determined by the linker. This avoids failures in creating
11255 subprocesses on Windows 7, see the discussion in this thread:
11256 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11258 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11260 Fix up display of the *Minibuf-0* buffer in the mini window.
11261 * keyboard.c (read_char): Don't clear the echo area if there's no
11263 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11264 contents of *Minibuf-0*) if there's no message displayed in its stead.
11266 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11268 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11271 2012-05-06 Chong Yidong <cyd@gnu.org>
11273 * lisp.mk (lisp): Update.
11275 2012-05-05 Jim Meyering <meyering@redhat.com>
11277 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11279 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11281 * data.c (PUT_ERROR): New macro.
11282 (syms_of_data): Use it. Add new error type `user-error'.
11283 * undo.c (user_error): New function.
11284 (Fprimitive_undo): Use it.
11285 * print.c (print_error_message): Adjust print style for `user-error'.
11286 * keyboard.c (user_error): New function.
11287 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11289 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11291 Do not limit current-time-string to years 1000..9999.
11292 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11293 (Fcurrent_time_string): Support any year that is supported by the
11294 underlying localtime representation. Don't use asctime, as it
11295 has undefined behavior for years outside the range -999..9999.
11297 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11299 Fix race conditions involving setenv, gmtime, localtime, asctime.
11300 Without this fix, interrupts could mess up code that uses these
11301 nonreentrant functions, since setting TZ invalidates existing
11302 tm_zone or tzname values, and since most of these functions return
11303 pointers to static storage.
11304 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11305 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11306 Grow the critical sections to include not just invoking
11307 localtime/gmtime, but also accessing these functions' results
11308 including their tm_zone values if any, and any related TZ setting.
11309 (format_time_string): Last arg is now struct tm *, not struct tm **,
11310 so that the struct tm is saved in the critical section.
11311 All callers changed. Simplify allocation of initial buffer, partly
11312 motivated by the fact that memory allocation needs to be outside
11313 the critical section.
11315 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11317 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11318 with RESET_INTERVAL.
11320 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11321 Remove duplicated buffer name initialization.
11323 2012-05-02 Jim Meyering <jim@meyering.net>
11325 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11327 * xfns.c (x_window): Use xstrdup (Bug#11375).
11329 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11331 * xdisp.c (pos_visible_p): If already at a newline from the
11332 display string before the 'while' loop, don't walk back the glyphs
11333 from it3.glyph_row. Solves assertion violation when the display
11334 string begins with a newline (egg.el). (Bug#11367)
11336 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11338 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11341 2012-05-01 Glenn Morris <rgm@gnu.org>
11343 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11344 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11345 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11346 All were removed before 23.1.
11348 * dispnew.c: Remove HAVE_LIBNCURSES test;
11349 it is always true on relevant platforms.
11351 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11352 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11354 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11356 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11358 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11359 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11362 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11364 Do not avoid creating empty evaporating overlays (Bug#9642).
11365 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11366 That is, do not delete an evaporating overlay if it becomes
11367 empty after its bounds are adjusted to fit within its buffer.
11368 This fix caused other problems, and I'm reverting it until we get
11369 to the bottom of them.
11371 2012-04-27 Chong Yidong <cyd@gnu.org>
11373 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11375 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11377 * xdisp.c (pos_visible_p): If the window start position is beyond
11378 ZV, start the display from buffer beginning. Prevents assertion
11379 violation in init_iterator when the minibuffer window is scrolled
11380 via the scroll bar.
11382 * window.c (window_scroll_pixel_based): Likewise.
11384 2012-04-27 Chong Yidong <cyd@gnu.org>
11386 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11388 2012-04-27 Glenn Morris <rgm@gnu.org>
11390 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11391 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11393 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11395 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11396 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11398 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11400 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11401 display element, check also the underlying string or buffer
11402 character. (Bug#11341)
11404 * w32menu.c: Include w32heap.h.
11405 (add_menu_item): If the call to AppendMenuW (via
11406 unicode_append_menu) fails, disable Unicode menus only if we are
11407 running on Windows 9X/Me.
11409 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11411 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11412 (xgetint): Add missing shift for LSB tags.
11414 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11416 * keyboard.c (read_char): Don't wipe echo area for select window
11417 events: These might get delayed via `mouse-autoselect-window'
11420 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11422 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11423 manipulation of :loaded-from data.
11425 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11427 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11428 now a cons (bug#11311).
11430 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11432 Do not create empty overlays with the evaporate property (Bug#9642).
11433 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11434 if it becomes empty after its bounds are adjusted to fit within
11435 its buffer. Without this fix, in a nonempty buffer (let ((o
11436 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11437 yields an empty overlay that has the evaporate property, which is
11438 not supposed to happen.
11440 Fix minor GTK3 problems found by static checking.
11441 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11442 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11443 (struct _EmacsFixedClass, emacs_fixed_get_type):
11444 Move decls here from emacsgtkfixed.h, since they needn't be public.
11445 (emacs_fixed_get_type): Now static.
11446 (emacs_fixed_class_init): Omit unused local.
11447 (emacs_fixed_child_type): Remove; unused.
11448 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11449 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11450 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11451 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11452 (EMACS_FIXED_GET_CLASS): Remove; unused.
11453 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11455 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11456 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11458 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11460 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11461 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11462 (__malloc_size_t, __malloc_ptrdiff_t):
11463 Remove. All uses removed, replaced by the definiens if needed,
11464 since we can assume C89 or better now.
11465 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11473 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11474 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11475 Define using prototypes, not old style.
11476 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11477 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11478 (align): Don't assume that signed integer overflow wraps around.
11479 Omit unused local var.
11480 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11481 (_free_internal_nolock, memalign, mallochook, reallochook):
11482 Omit no-longer-needed casts.
11483 (valloc): Use getpagesize, not __getpagesize.
11484 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11485 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11487 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11489 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11491 Move functions from C to Lisp. Make non-blocking method calls
11492 the default. Implement further D-Bus standard interfaces.
11494 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

11510 (xd_signature, xd_append_arg): Allow float for integer types.
11511 (xd_get_connection_references): New function.
11512 (xd_get_connection_address): Rename from xd_initialize.
11513 Return cached address.
11514 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
11515 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp
11517 (Fdbus_init_bus): New optional arg PRIVATE. Cache address.
11518 Return number of refcounts.
11519 (Fdbus_get_unique_name): Make stronger parameter check.
11520 (Fdbus_message_internal): New defun.

11549 2012-04-22 Leo Liu <sdl.web@gmail.com>
11551 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
11553 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11555 * sysdep.c [__FreeBSD__]: Minor cleanups.
11556 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11557 Use Emacs indenting style more consistently. Avoid some casts.
11558 Use 'double' consistently rather than mixing 'float' and 'double'.

11562 * sysdep.c (list_system_processes, system_process_attributes):
11563 Add implementation for FreeBSD (Bug#5243).

11569 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11571 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11572 It is never used otherwise.
11574 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11576 * print.c (print_preprocess): Only check print_depth if print-circle
11578 (print_object): Check for cycles even when print-circle is nil and
11579 print-gensym is t, but only check print_depth if print-circle is nil.
11581 2012-04-20 Chong Yidong <cyd@gnu.org>
11583 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11584 set the status to "failed" and ensure that sentinel is run.
11586 2012-04-20 Glenn Morris <rgm@gnu.org>
11588 * process.c (Fset_process_inherit_coding_system_flag)
11589 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

11599 farther than the first row after the header line, if any.
11600 Don't consider the header-line row as "partially visible", even if
11601 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
11603 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

11617 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11618 -Wunused-result, -Wunused-variable. This should go away once
11619 the Emacs and Gnulib regex code is merged.
11620 (xmalloc, xrealloc): Now static.
11622 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

11639 New extern decls, to avoid calling undeclared functions.
11640 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11641 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11642 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11643 (NEED_MEM_INSERT): New macro.
11644 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11645 Remove one incorrect comment and fix another.

11660 Remove decls. This fixes an "It stinks!".
11662 * alloc.c (which_symbols): Fix alignment issue / type clash.
11664 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11666 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11667 (struct Lisp_Misc_Any): Likewise.
11668 (struct Lisp_Free): Likewise.
11669 * alloc.c (union aligned_Lisp_Symbol): Define.

11681 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11682 * s/netbsd.h, s/sol2-6.h:
11683 Remove definition of GC_MARK_STACK, since the default now works.
11684 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

11686 no longer the default.
11687 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11689 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11691 * lread.c (lisp_file_lexically_bound_p):
11692 Fix hang at ";-*-\n" (bug#11238).
11694 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11696 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
11697 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

11710 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11712 2012-04-11 Daniel Colascione <dancol@dancol.org>
11714 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11715 against is gone. It's better to use vfork now so that when Cygwin
11716 gains a new, working vfork, we use it automatically (bug#10398).
11718 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11720 * window.c (save_window_save): Obey window-point-insertion-type.

11738 * w32.c (w32_delayed_load): Record the full path of the library
11739 being loaded (bug#10424).
11741 2012-04-09 Glenn Morris <rgm@gnu.org>
11743 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11744 not just in the obarray, before snarfing them. (Bug#11036)

11761 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11762 attempts per process (connection).
11764 2012-04-09 Chong Yidong <cyd@gnu.org>
11766 * eval.c (Fuser_variable_p, user_variable_p_eh)

11768 (Fdefvar): Caller changed.
11770 * callint.c (Finteractive, Fcall_interactively):
11771 * minibuf.c (Fread_variable): Callers changed.
11773 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11775 * xdisp.c (set_cursor_from_row): If the display string appears in
11776 the buffer at position that is closer to point than the position
11777 after the display string, display the cursor on the first glyph of
11778 the display string. Fixes cursor display when a 'display' text
11779 property immediately follows invisible text. (Bug#11094)
11781 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11783 composite.c: use 'double' consistently
11784 * composite.c (get_composition_id): Use 'double' consistently
11785 instead of converting 'float' to 'double' and vice versa; this is
11786 easier to understand and avoids a GCC warning.
11788 2012-04-09 Glenn Morris <rgm@gnu.org>
11790 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11791 preparation for dumping it with emacs. (Bug#4789)

11813 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11814 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11815 objects, as mark_maybe_pointer will catch them otherwise.
11816 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11817 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

11829 (GLOBAL_SOURCES): Add xml.c.
11830 ($(BLD)/xml.$(O)): New dependency list.
11832 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11833 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11834 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11835 [!WINDOWSNT]: New macros.
11836 (init_libxml2_functions, libxml2_loaded_p): New functions.
11837 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11838 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11839 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11840 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11842 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11843 Call init_libxml2_functions before calling libxml2 functions.
11844 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11846 * emacs.c: Don't include libxml/parser.h.
11847 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11848 xmlCleanupParser directly.

11852 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11854 * indent.c (Fvertical_motion): If there is a display string at
11855 point, use it.vpos to compute how many lines to backtrack after
11856 move_it_to point. (Bug#11133)
11858 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11860 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11861 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11862 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11863 macros related to unification of CJK characters. For the details,
11864 see the discussion following the message here:
11865 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11867 2012-04-04 Chong Yidong <cyd@gnu.org>
11869 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11871 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11873 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

11881 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11883 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11884 position we get to after a call to move_it_to fails the
11885 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11886 only if we wind up in a string from display property. (Bug#11063)
11888 * window.c (Fdelete_other_windows_internal): Invalidate the row
11889 and column information about mouse highlight, so that redisplay
11890 restores it after reallocating the glyph matrices. (Bug#7464)
11892 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11893 string comes from a `display' text property, use the buffer
11894 position of that property as if we actually saw that position in
11896 (move_it_by_lines): Remove the assertion that
11897 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11898 violated when there's a before-string at the beginning of a line.
11901 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11903 * xdisp.c (append_space_for_newline): If the default face was

11905 (extend_face_to_end_of_line): Use the remapped default face for
11906 extending the face to the end of the line.
11907 (display_line): Call extend_face_to_end_of_line when the default
11908 face was remapped. (Bug#11068)
11910 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11912 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11914 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

11930 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11931 (command_loop_1): Use it; inhibit selection update for

11936 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11938 2012-03-25 Kenichi Handa <handa@m17n.org>
11940 * dispextern.h (struct glyph): Change the bit length of
11941 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11943 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11945 * s/ms-w32.h (tzname): Include time.h before redirecting to

11954 !SYNC_INPUT. (Bug#11080)
11956 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11958 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11959 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11960 when fetching a multibyte character consumes more bytes than
11961 CHAR_BYTES returns, due to unification of CJK characters in
11962 string_char. (Bug#11073)
11964 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11966 * process.c (wait_reading_process_output): Handle pty disconnect
11967 by refraining from sending oneself a SIGCHLD (bug#10933).
11969 2012-03-22 Chong Yidong <cyd@gnu.org>
11971 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11973 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11974 Mark string as coming from a prefix property.
11975 (handle_face_prop): Use default face for prefix strings (Bug#4281).

11996 it fit in a valid range (Bug#11003).
11998 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12000 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12001 that is not from display property, accept the row as a "cursor
12002 row" if one of the string's character has a non-nil `cursor'
12003 property. Fixes cursor positioning when there are newlines in
12004 overlay strings, e.g. in icomplete.el. (Bug#11035)
12006 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12008 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

12037 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12040 2012-03-03 Glenn Morris <rgm@gnu.org>
12042 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12044 2012-03-02 Eli Zaretskii <eliz@gnu.org>

12055 * buffer.c (buffer-list-update-hook): Doc fix.
12057 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12059 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12060 push_it before setting up the iterator for the first overlay
12061 string, even if we have an empty string loaded.
12062 (next_overlay_string): If there's an empty string on the iterator
12063 stack, pop the stack. (Bug#10903)
12065 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12067 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12068 Suggested by Stefan Monnier in
12069 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12070 * alloc.c (widen_to_Lisp_Object): New static function.
12071 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12072 and widening them to Lisp_Objects. This would work even if
12073 USE_LSB_TAG is defined and wide integers are used, which might
12074 happen in a future version of Emacs.
12076 2012-02-25 Chong Yidong <cyd@gnu.org>
12078 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12083 before saving to clipboard manager.
12085 2012-02-24 Chong Yidong <cyd@gnu.org>
12087 * keyboard.c (process_special_events): Handle all X selection
12088 requests in kbd_buffer, not just the next one (Bug#8869).
12090 2012-02-23 Chong Yidong <cyd@gnu.org>
12092 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12093 call when setting menu-bar-lines and tool-bar-lines parameters.
12094 (unwind_create_frame_1): New helper function.
12096 * window.c (inhibit_window_configuration_change_hook): New var.

12107 * fileio.c (Vfile_name_handler_alist): Doc fix.
12109 * buffer.c (Fget_file_buffer): Protect against invalid file
12110 handler return value.

12115 when computing $valmask.
12117 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12118 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12119 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12120 It's useless in that case, and it can cause problems on hosts
12121 that allocate halves of EMACS_INT values separately.
12122 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12123 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12124 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12125 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12126 it avoids undefined behavior on hosts where shifting right by more
12127 than the word width has undefined behavior.
12129 2012-02-19 Chong Yidong <cyd@gnu.org>
12131 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12132 (Funhandled_file_name_directory, Ffile_name_as_directory)
12133 (Fdirectory_file_name, Fexpand_file_name)
12134 (Fsubstitute_in_file_name): Protect against invalid file handler
12135 return values (Bug#10845).

12149 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12151 2012-02-15 Chong Yidong <cyd@gnu.org>
12153 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12154 marked as special. Also, starting docstrings with * is obsolete.

12169 2012-02-12 Chong Yidong <cyd@gnu.org>
12171 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12172 as that creates a dangerous corner case.
12174 * window.c (Fdelete_window_internal): Invalidate the mouse
12175 highlight (Bug#9904).
12177 2012-02-12 Glenn Morris <rgm@gnu.org>

12182 * nsselect.m (Fx_own_selection_internal)
12183 (Fx_disown_selection_internal, Fx_selection_exists_p)
12184 (Fx_selection_owner_p, Fx_get_selection_internal):
12185 Sync docs and argument specs with the xselect.c versions.
12187 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

12207 2012-02-07 Chong Yidong <cyd@gnu.org>
12209 * buffer.c (Fbuffer_local_variables)
12210 (buffer_lisp_local_variables): Handle unbound vars correctly;
12211 don't let Qunbound leak into Lisp.
12213 2012-02-07 Glenn Morris <rgm@gnu.org>
12215 * image.c (Fimagemagick_types): Doc fix.
12217 * image.c (imagemagick-render-type): Change it from a lisp object
12218 to an integer. Move the doc here from the lisp manual.

12235 2012-02-04 Eli Zaretskii <eliz@gnu.org>
12237 * w32.c (get_emacs_configuration_options):
12238 Include --enable-checking, if specified, in the return value.

12248 before BEGV. (Bug#10696)
12250 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12252 Handle overflow when computing char display width (Bug#9496).
12253 * character.c (char_width): Return EMACS_INT, not int.
12254 (char_width, c_string_width): Check for overflow when
12255 computing the width; this is possible now that individual
12256 characters can have unbounded width. Problem introduced
12257 by merge from Emacs 23 on 2012-01-19.

12277 0, do not call append_composite_glyph.
12279 2012-02-02 Kenichi Handa <handa@m17n.org>
12281 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12283 (x_produce_glyphs): If the component of a composition is a null
12284 string, set it->pixel_width to 1 to avoid zero-width glyph.

12288 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12289 first 2 arguments are identical. This makes inserting large
12290 output from a subprocess an order of magnitude faster on
12291 MS-Windows, where all sbrk'ed memory is always contiguous.
12293 2012-01-31 Glenn Morris <rgm@gnu.org>

12386 Update template values to be closer to their typical values these days.
12388 2012-01-09 Eli Zaretskii <eliz@gnu.org>
12390 * xdisp.c (rows_from_pos_range): Accept additional argument
12391 DISP_STRING, and accept any glyph in a row whose object is that
12392 string as eligible for mouse highlight. Fixes mouse highlight of
12393 display strings from overlays. (Bug#10464)
12395 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
12397 emacs: fix an auto-save permissions race condition (Bug#10400)
12398 * fileio.c (auto_saving_dir_umask): New static var.
12399 (Fmake_directory_internal): Use it.
12400 (do_auto_save_make_dir): Set it, instead of invoking chmod after

12404 (Fdo_auto_save): Catch all errors, not just file errors, so
12405 that the var is always cleared.

12462 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
12463 property that ends at ZV, so that the bidi iteration could be

12744 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12745 verifies glyph row's hash code--we have just reallocated the

12907 Otherwise, valgrind does not work on some platforms.
12908 Problem reported by Andreas Schwab in
12909 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12910 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12911 is set, removing the need for VIRT_ADDRESS_VARIES.
12912 (PURE_P): Use a more-efficient implementation that needs just one
12913 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12914 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12915 to 4 (xorl, subq, cmpq, setbe).
12916 * alloc.c (pure): Always extern now, since that's the
12917 VIRT_ADDR_VARIES behavior.
12918 (PURE_POINTER_P): Use a single comparison, not two, for
12919 consistency with the new puresize.h.
12920 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12921 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
12922 Remove VIRT_ADDR_VARIES no longer needed.
12924 2011-11-19 Eli Zaretskii <eliz@gnu.org>
12926 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
12927 (erase_phys_cursor, update_window_cursor, show_mouse_face)

13390 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
13391 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
13392 (g_b_init_get_glyph_outline_w): New static variables.
13393 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
13394 (GetGlyphOutlineW_Proc): New typedefs.
13395 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
13396 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13398 (w32font_open_internal, compute_metrics):
13399 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13400 instead of calling the "wide" APIs directly.
13402 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13404 * w32.h (syms_of_w32font): Add prototype.
13406 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13408 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13409 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13410 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13411 (Fmove_to_window_line): Doc fix.
13413 2011-10-27 Chong Yidong <cyd@gnu.org>
13415 * process.c (make_process): Set gnutls_state to NULL.
13417 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13418 non-NULL, regardless of GNUTLS_INITSTAGE.
13419 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13420 an error. Set process slots as soon as we allocate them.
13422 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13424 2011-10-27 Chong Yidong <cyd@gnu.org>
13426 * gnutls.c (emacs_gnutls_deinit): New function.
13427 Deallocate credentials structures as well as calling gnutls_deinit.
13428 (Fgnutls_deinit, Fgnutls_boot): Use it.
13430 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13431 (deactivate_process): Call emacs_gnutls_deinit.
13433 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13435 * image.c (x_create_x_image_and_pixmap):
13436 * w32.c (sys_rename, w32_delayed_load):
13437 * w32font.c (fill_in_logfont):
13438 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13440 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13442 * w32fns.c (w32_default_color_map): New function,
13443 extracted from Fw32_default_color_map.
13444 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13446 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13448 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13450 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13452 * keyboard.c (test_undefined): New function (bug#9751).
13453 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13455 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13457 * sysdep.c (init_sys_modes): Fix the check for the controlling
13458 terminal (Bug#6649).
13460 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13462 * dispextern.h (struct bidi_it): New member next_en_type.
13464 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13465 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13466 current character, check also for next_en_type being WEAK_EN.
13467 (bidi_resolve_weak): Don't enter the expensive loop if the current
13468 position is before next_en_pos. Record the bidi type of the first
13469 non-ET, non-BN character we find, in addition to its position.
13470 (bidi_level_of_next_char): Invalidate next_en_type when
13471 next_en_pos is over-stepped.
13473 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13475 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13476 * editfns.c: Rewrite current-time-zone so that it invokes
13477 the equivalent of (format-time-string "%Z") to get the time zone name.
13478 This fixes a bug when the time zone name contains characters that
13479 need converting from the system time locale to Emacs internal format.
13480 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13481 that patch fixed format-time-string to do the conversion, but
13482 I forgot to fix current-time-zone.
13483 (format_time_string): New function, containing most of
13484 what Fformat_time_string used to contain.
13485 (Fformat_time_string): Rewrite in terms of format_time_string.
13486 This doesn't change this function's behavior.
13487 (current-time-zone): Rewrite to use format_time_string.
13488 This fixes the bug reported by Michael Schierl in
13489 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13490 Jason Rumney's 2007-06-07 change worked around this bug, but
13492 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13494 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13496 * xdisp.c (start_display): If the character at POS is displayed
13497 via a display vector, reset IT->current.dpvec_index to zero.
13498 (try_window_reusing_current_matrix): If a line ends in a display
13499 vector or the next line starts in a display vector, continue
13500 redrawing the window even though the character position of
13501 start_row was reached.
13504 2011-10-18 Chong Yidong <cyd@gnu.org>
13506 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13507 with nobreak-char-display too.
13509 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13511 Fix part 3 of bug#9771.
13512 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13513 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13514 non-neutral characters if the current character is a paragraph
13515 separator (a.k.a. Newline). This avoids running the same
13516 expensive loop twice, once when we consume the preceding newline
13517 and the other time when the line actually needs to be displayed.
13518 Avoid the loop when we see neutrals on the base embedding level
13519 following a character whose directionality is the same as the
13520 paragraph's. This avoids running the expensive loop when a line
13521 ends in a long sequence of neutrals, like control characters.
13522 Add assertion against STRONG_AL type. Slightly rearrange code
13523 that determines the type of a neutral given the first non-neutral
13525 (bidi_level_of_next_char): Set next_en_pos to zero when
13526 invalidating its info.
13528 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13530 * xdisp.c (push_display_prop): Determine whether to record string
13531 or buffer position by IT->string, not by IT->method. Allow
13532 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13533 (move_it_vertically_backward): Don't look for character position
13534 immediately after the newline when in a continuation line.
13537 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13539 * window.c (coordinates_in_window): Rewrite and delabelize
13540 vertical border check. (Bug#5357) (Bug#9618)
13542 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13544 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13545 errors in XSetWindowBorder (bug#9310).
13547 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13549 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13550 avoid crash when xmalloc overrun checking is enabled.
13552 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13554 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13555 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13556 cursor motion with <left> and <right> arrow keys.
13558 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13559 some callers set that themselves.
13561 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13563 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13564 display string and the previous row comes from the same string and
13565 is empty. (Bug#9739) (Bug#9738)
13567 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13569 * doc.c (get_doc_string): Encode file name (bug#9735).
13571 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13573 * bidi.c (bidi_level_of_next_char):
13574 * xdisp.c (get_visually_first_element): Remove old incorrect
13575 comments regarding the Unicode Line Separator character.
13577 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13579 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13581 * alloc.c (Fgc_status): Do not access beyond zombies array
13582 boundary if nzombies > MAX_ZOMBIES.
13583 * alloc.c (dump_zombies): Add missing format specifier.
13585 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13587 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13588 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13590 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13591 Some packages use them to denote characters with modifiers.
13593 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13595 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13596 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13597 matching a pp-number. Rename parameter var to var1.
13599 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13601 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13603 2011-10-08 Glenn Morris <rgm@gnu.org>
13605 * callint.c (Fcall_interactively): Give a more explicit error for the
13606 'c' case with a non-character input. (Bug#8479)
13608 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13610 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13612 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13613 lines that are hscrolled on the left.
13615 * dispnew.c (buffer_posn_from_coords): Account for a possible
13616 presence of header-line. (Bug#4426)
13618 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13620 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13621 Don't advertise functionality which we discourage or doesn't work.
13623 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13625 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13626 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13627 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13628 this makes Emacs dump core during garbage collection on rare
13629 occasions. sizeof is obviously inferior to offsetof here, so
13630 stick with offsetof.
13631 (GC_POINTER_ALIGNMENT): New macro.
13632 (mark_memory): Omit 3rd (offset) arg; caller changed.
13633 Don't assume EMACS_INT alignment is the same as pointer alignment.
13635 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13637 * keyboard.c (read_key_sequence_remapped): New var.
13638 (read_key_sequence): Compute remapping in the right buffer.
13639 (command_loop_1): Use read_key_sequence's remapping directly.
13641 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13643 * dired.c (file_name_completion): Don't expand file name.
13644 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13645 before checking file name handler.
13647 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13648 they've been requested explicitly (bug#9591).
13650 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13652 * keymap.c (Fsingle_key_description): Use make_specified_string
13653 instead of build_string to build string from push_key_description.
13656 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13658 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13659 This fixes a Y2038 bug on 64-bit hosts.
13660 * buffer.c (reset_buffer):
13661 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13662 (Fclear_buffer_auto_save_failure):
13663 Use 0, not -1, to represent an unset failure time, since time_t
13664 might not be signed.
13666 Remove dependency on glibc malloc internals.
13667 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13668 Move back here from lisp.h, but with their new implementations.
13669 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13670 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13671 * charset.c (charset_table_init): New static var.
13672 (syms_of_charset): Use it instead of xmalloc. This removes a
13673 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13674 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13675 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13676 Move back to alloc.c.
13677 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13678 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13680 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13682 * nsterm.m (windowDidResize): Call x_set_window_size only when
13683 ns_in_resize is true. Otherwise set pixelwidth/height and
13684 call change_frame_size (Bug#9628).
13686 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13688 Port --enable-checking=all to Fedora 14 x86-64.
13689 * charset.c (syms_of_charset): Also account for glibc malloc's
13690 internal overhead when calculating the initial malloc maximum.
13692 Port --enable-checking=all to Fedora 14 x86.
13693 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13695 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13696 (overrun_check_realloc, overrun_check_free):
13697 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13698 That way, xmalloc returns a properly-aligned pointer even if
13699 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13700 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13701 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13702 into account when calculating the initial malloc maximum.
13703 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13704 Move here from alloc.c, so that charset.c can use it too.
13705 Properly align; the old code wasn't right for common 32-bit hosts
13706 when configured with --enable-checking=all.
13707 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13708 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13710 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13712 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13715 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13717 * xdisp.c (compute_display_string_end): If there's no display
13718 string at CHARPOS, return -1.
13720 * bidi.c (bidi_fetch_char): When compute_display_string_end
13721 returns a negative value, treat the character as a normal
13722 character not covered by a display string. (Bug#9624)
13724 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13726 * lread.c (Fread_from_string): Fix typo in docstring.
13728 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13730 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13731 newline, reseat the iterator instead of bidi-iterating there one
13732 character at a time. (Bug#9610)
13733 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13734 TO_CHARPOS if the bidi iterator is at base embedding level.
13736 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13738 * lread.c (readevalloop): Use correct code for NBSP.
13739 (read1): Likewise. (Bug#9608)
13741 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13743 * dbusbind.c (Fdbus_register_signal): When service is not
13744 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13746 2011-09-25 Glenn Morris <rgm@gnu.org>
13748 * buffer.c (truncate-lines): Doc fix.
13750 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13752 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13753 (Fset_window_next_buffers): Doc fix.
13755 2011-09-24 Glenn Morris <rgm@gnu.org>
13757 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13759 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13761 Fix minor problems found by static checking.
13762 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13763 * indent.c (Fvertical_motion): Fix == vs = typo.
13765 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13767 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13768 Default value is now t. Doc fix.
13770 * indent.c (Fvertical_motion): Compute and apply the overshoot
13771 logic when moving up, not only when moving down. Fix the
13772 confusing name and values of the it_overshoot_expected variable;
13773 logic changes accordingly. (Bug#9254) (Bug#9549)
13775 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13776 CHARPOS is covered by a display string which includes newlines.
13777 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13778 is covered by a display string with embedded newlines.
13780 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13782 * dbusbind.c (Fdbus_register_signal): Add match rule to
13783 Vdbus_registered_objects_table. (Bug#9581)
13784 (Fdbus_register_method, Vdbus_registered_objects_table):
13787 2011-09-24 Jim Meyering <meyering@redhat.com>
13789 do not ignore write error for any output size
13790 The previous change was incomplete.
13791 While it makes emacs --batch detect the vast majority of stdout
13792 write failures, errors were still ignored whenever the output size is
13793 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13794 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13795 && echo FAIL: ignored write error
13796 FAIL: ignored write error
13797 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13798 && echo FAIL: ignored write error
13799 FAIL: ignored write error
13800 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13802 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13804 * emacs.c (Fkill_emacs): In noninteractive mode exit
13805 non-successfully if a write error occurred on stdout. (Bug#9574)
13807 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13809 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13812 * dispextern.h (struct it): Update the comment documenting what
13815 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13817 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13818 a display string, extend search for cursor position to end of row.
13819 (find_row_edges): If the row ends in a newline from a display
13820 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13821 Handle the case of a display string with multiple newlines.
13822 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13823 non-empty line. Fixes confusing cursor motion with arrow keys at
13824 the beginning of a line that starts with whitespace.
13826 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13828 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13831 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13833 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13834 boolean (Bug#9154).
13836 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13838 * xdisp.c (display_line): Record maximum and minimum buffer
13839 positions even if no glyphs were produced (e.g., by a zero-width
13840 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13841 buffer positions that will be removed from the glyph row because
13843 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13844 column is beyond frame width: don't subtract 1 "pixel" when
13845 computing width of the stretch.
13846 (reseat_at_next_visible_line_start): Undo the change made on
13847 2011-09-17 that saved paragraph information and restored it after
13848 the call to `reseat'. (Bug#9545)
13850 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13852 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13853 and turn window cursor on if cleared (Bug#9415).
13855 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13857 * search.c (boyer_moore): Take unibyte characters from pattern
13858 literally. (Bug#9458)
13860 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13862 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13864 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13866 Fix minor problem found by static checking.
13867 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13868 initialized, to pacify gcc -Wuninitialized.
13870 * fileio.c: Report proper errno when syscall falls.
13871 (Finsert_file_contents): Save and restore errno,
13872 so that report_file_error outputs the correct diagnostic.
13873 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13875 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13877 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13879 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13881 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13882 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13884 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13886 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13887 about the current paragraph and restore it after the call to reseat.
13889 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13890 (bidi_find_paragraph_start): Search back for paragraph beginning
13891 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13892 (bidi_move_to_visually_next): Only trigger paragraph-related
13893 computations when the last character is a newline or at EOB, not
13894 just any NEUTRAL_B. (Bug#9470)
13896 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13897 truncated lines if point is covered by a display string. (Bug#9524)
13899 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13901 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13902 (cons_to_x_long): New function.
13903 (lisp_data_to_selection_data): Use it. Correct the test for
13904 short-versus-long data; it was negated. Break out of vector
13905 loop, for efficiency, when a long datum is discovered.
13907 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13909 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13911 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13913 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13914 GCC PR/17406) by declaring this function with external scope.
13916 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13918 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13919 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13921 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13923 * editfns.c (Fformat): Correctly handle text properties on "%%".
13925 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13927 * xterm.c (x_draw_composite_glyph_string_foreground):
13928 * w32term.c (x_draw_composite_glyph_string_foreground):
13929 * term.c (encode_terminal_code):
13930 * composite.c (composition_update_it, get_composition_id):
13931 * xdisp.c (get_next_display_element)
13932 (fill_composite_glyph_string): Add comments about special meaning
13933 of TAB characters in a composition.
13935 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13937 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13938 This occurs when processing a multibyte format.
13939 Problem reported by Wolfgang Jenker.
13941 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13943 * xdisp.c (try_cursor_movement): Only check for exact match if
13944 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13946 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13948 Remove unused external symbols.
13949 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13950 * xdisp.c (calc_pixel_width_or_height): Now static.
13951 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13952 * indent.c (check_display_width):
13953 * w32term.c: Fix comment to match code.
13954 * xterm.c, xterm.h (x_catching_errors): Remove.
13956 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13958 * xselect.c: Use signed conversions more consistently (Bug#9498).
13959 (selection_data_to_lisp_data): Assume incoming selection data are
13960 signed integers, not unsigned. This is to be consistent with
13961 outgoing selection data, which was modified to use signed integers
13962 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13963 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13964 expects long, not unsigned long.
13966 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13968 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13969 computation of loop end. Reported by Johan Bockgård
13972 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13974 * frame.c (Fother_visible_frames_p): Function deleted.
13976 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13978 * indent.c (compute_motion): Process display vector front to back
13979 rather than the other way around. (Bug#2496)
13981 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13983 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13985 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13987 * minibuf.c (Fread_from_minibuffer): Doc fix.
13989 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13991 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13992 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13994 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13996 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13997 value for non-existent files.
13999 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14001 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14002 set its "size" to -1. This will set the modtime_size field of
14003 the corresponding buffer to -1, which is what
14004 verify-visited-file-modtime expects for files that do not exist.
14007 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14009 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14011 * lisp.h: ... from here. push_key_description is no longer
14012 defined in keyboard.c, so its declaration should not be in
14013 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14014 logically belongs with push_key_description.
14016 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14018 * buffer.h: Include <sys/types.h> instead of <time.h>.
14019 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14020 Problem reported by Herbert J. Skuhra.
14022 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14024 * xml.c (parse_region): Make the parsing work for
14025 non-comment-starting XML files again (bug#9144).
14027 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14029 * image.c (gif_load): Fix calculation of bottom and right corner.
14032 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14034 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14035 redisplay in small windows.
14037 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14039 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14041 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14043 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14044 Operate on live windows only.
14046 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14048 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14050 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14052 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14053 only under bidi iteration.
14055 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14057 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14059 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14061 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14062 Without this fix, the command to link temacs failed due to an
14063 undefined symbol __builtin_isnan. This is because
14064 /usr/include/iso/math_c99.h #defines isnan(x) to
14065 __builtin_isnan(x), but the bundled gcc, which identifies itself
14066 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14068 * floatfns.c (isnan): #undef, and then #define to a clone of
14070 (Fisnan): Always define, since it's always available now.
14071 (syms_of_floatfns): Always define isnan at the Lisp level.
14073 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14075 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14077 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14079 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14080 The previous code assumed that file offsets (off_t values) fit in
14081 EMACS_INT variables, which is not true on typical 32-bit hosts.
14082 The code messed up by falsely reporting buffer overflow in cases
14083 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14084 when "big" contains more than 2**29 bytes, even though this
14085 inserts just one byte and does not overflow the buffer.
14086 (Finsert_file_contents): Store file offsets as off_t
14087 values, not as EMACS_INT values. Check for overflow when
14088 converting between EMACS_INT and off_t. When checking for
14089 buffer overflow or for overlap, take the offsets into account.
14090 Don't use EMACS_INT for small values where int suffices.
14091 When checking for overlap, fix a typo: ZV was used where
14092 ZV_BYTE was intended.
14093 (Fwrite_region): Don't assume off_t fits into 'long'.
14094 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14096 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14098 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14100 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14102 sprintf-related integer and memory overflow issues (Bug#9412).
14104 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14105 (esprintf, exprintf, evxprintf): New functions.
14106 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14107 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14108 (modify_event_symbol): Do not assume that the length of
14109 name_alist_or_stem is safe to alloca and fits in int.
14110 (Fexecute_extended_command): Likewise for function name and binding.
14111 (Frecursion_depth): Wrap around reliably on integer overflow.
14112 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14113 since some callers pass EMACS_INT values.
14114 (Fsingle_key_description): Don't crash if symbol name contains more
14115 than MAX_ALLOCA bytes.
14116 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14117 (get_minibuffer): Arg is now EMACS_INT, not int.
14118 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14119 (esprintf, exprintf, evxprintf): New decls.
14120 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14122 * dbusbind.c (signature_cat): New function.
14123 (xd_signature, Fdbus_register_signal):
14124 Do not overrun buffer; instead, report string overflow.
14126 * dispnew.c (add_window_display_history): Don't overrun buffer.
14127 Truncate instead; this is OK since it's just a log.
14129 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14130 even if the time zone offset is outlandishly large.
14131 Don't mishandle offset == INT_MIN.
14133 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14134 when creating daemon; the previous buffer-overflow check was incorrect.
14136 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14137 which has the guts of the old verror function.
14139 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14140 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14142 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14143 (font_unparse_xlfd): Don't blindly alloca long strings.
14144 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14145 fits in int, when using sprintf. Use single snprintf to count
14146 length of string rather than counting it via multiple sprintfs;
14147 that's simpler and more reliable.
14148 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14149 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14150 sprintf, in case result does not fit in int.
14152 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14153 (fontset_from_font): Print it.
14155 * frame.c (tty_frame_count): Now printmax_t, not int.
14156 (make_terminal_frame, set_term_frame_name): Print it.
14157 (x_report_frame_params): In X, window IDs are unsigned long,
14158 not signed long, so print them as unsigned.
14159 (validate_x_resource_name): Check for implausibly long names,
14160 and don't assume name length fits in 'int'.
14161 (x_get_resource_string): Don't blindly alloca invocation name;
14162 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14165 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14166 (xg_check_special_colors, xg_set_geometry):
14167 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14169 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14170 Use esprintf, not sprintf, in case result does not fit in int.
14172 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14173 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14174 it as a large positive number.
14175 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14176 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14178 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14179 in case result does not fit in int.
14181 * print.c (float_to_string): Detect width overflow more reliably.
14182 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14183 buffer overrun. Don't assume list length fits in 'int'. Treat
14184 print length of 0 as 0, not as infinity; to be consistent with other
14185 uses of print length in this function. Don't overflow print length
14186 index. Don't assume hash table size fits in 'long', or that
14187 vectorlike size fits in 'unsigned long'.
14189 * process.c (make_process): Use printmax_t, not int, to format
14190 process-name gensyms.
14192 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14194 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14195 to avoid potential buffer overrun.
14197 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14198 if X resource line is longer than 512 bytes.
14200 * xfns.c (x_window): Make sprintf buffer a bit bigger
14201 to avoid potential buffer overrun.
14203 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14205 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14207 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14209 Integer overflow fixes for scrolling, etc.
14210 Without these, Emacs silently mishandles large integers sometimes.
14211 For example, "C-u 4294967297 M-x recenter" was treated as if
14212 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14214 * xdisp.c (try_window_id): Check Emacs fixnum range before
14215 converting to 'int'.
14217 * window.c (window_scroll_line_based, Frecenter):
14218 Check that an Emacs fixnum is in range before assigning it to 'int'.
14219 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14220 values converted from Emacs fixnums.
14221 (Frecenter): Don't wrap around a line count if it is out of 'int'
14222 range; instead, treat it as an extreme value.
14223 (Fset_window_configuration, compare_window_configurations):
14224 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14226 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14227 that can exceed INT_MAX. Check that EMACS_INT value is in range
14228 before assigning it to the (possibly-narrower) index.
14229 (match_limit): Don't assume that a fixnum can fit in 'int'.
14231 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14234 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14235 (Fvertical_motion): Don't wrap around LINES values that don't fit
14236 in 'int'. Instead, treat them as extreme values. This is good
14237 enough for windows, which can't have more than INT_MAX lines anyway.
14239 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14241 * Require libxml/parser.h to avoid compilation warning.
14243 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14245 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14246 since this reportedly can destroy thread storage.
14248 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14250 * syntax.c (find_defun_start): Update all cache variables if
14251 exiting early (Bug#9401).
14253 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14255 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14257 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14258 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14259 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14261 * term.c (tty_append_glyph): New function.
14262 (produce_stretch_glyph): Static function and its prototype deleted.
14264 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14267 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14269 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14270 when checking :margin (Bug#9390).
14271 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14272 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14273 so that the name doesn't mislead. All uses changed.
14275 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14277 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14280 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14282 * xdisp.c (move_it_to): Don't bail out early when reaching
14283 position beyond to_charpos, if we are scanning backwards.
14284 (move_it_vertically_backward): When DY == 0, make sure we get to
14285 the first character in the line after the newline.
14287 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14289 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14290 (ccl_driver): Do not generate an out-of-range pointer.
14291 (Fccl_execute_on_string): Remove unnecessary check for
14292 integer overflow, noted by Stefan Monnier in
14293 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14294 Remove a FIXME that didn't need fixing.
14295 Simplify the newly-introduced buffer reallocation code.
14297 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14299 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14301 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14303 Integer and memory overflow issues (Bug#9196).
14305 * doc.c (get_doc_string): Rework so that
14306 get_doc_string_buffer_size is the actual buffer size, rather than
14307 being 1 less than the actual buffer size; this makes xpalloc more
14310 * image.c (x_allocate_bitmap_record, cache_image):
14311 * xselect.c (Fx_register_dnd_atom):
14312 Simplify previous changes by using xpalloc.
14314 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14315 since either will do and ptrdiff_t is convenient with xpalloc.
14317 * charset.c (charset_table_size)
14318 (struct charset_sort_data.priority): Now ptrdiff_t.
14319 (charset_compare): Don't overflow if priorities differ greatly.
14320 (Fsort_charsets): Don't assume list length fits in int.
14321 Check for size-calculation overflow when allocating sort data.
14322 (syms_of_charset): Allocate an initial charset table that is
14323 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14325 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14327 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14328 The actual value is always <= INT_MAX, and leaving it unsigned made
14329 overflow checking harder.
14331 * dispextern.h (struct glyph_matrix.rows_allocated)
14332 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14333 with xpalloc. The values are still always <= INT_MAX.
14335 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14337 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14338 (SAFE_NALLOCA): New macro.
14340 * region-cache.c (struct boundary.pos, find_cache_boundary)
14341 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14342 (set_cache_region, invalidate_region_cache)
14343 (revalidate_region_cache, know_region_cache, region_cache_forward)
14344 (region_cache_backward, pp_cache):
14345 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14346 so that ptrdiff_t * can be passed to xpalloc.
14347 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14348 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14349 (pp_cache): Don't assume cache_len fits in int.
14350 * region-cache.h: Adjust extern decls to match.
14352 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14353 EMACS_INT, since either will do, for xpalloc.
14355 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14356 (xnmalloc, xnrealloc, xpalloc): New functions.
14358 * bidi.c (bidi_shelve_header_size): New constant.
14359 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14360 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14362 * bidi.c (bidi_cache_shrink):
14363 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14365 Don't update size of array until after memory allocation succeeds,
14366 because xmalloc/xrealloc may not return.
14367 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14368 now that we have proper integer overflow checking.
14369 (record_overlay_string, overlay_strings): Catch overflows when
14370 calculating size of overlay_str_buf.
14372 * callproc.c (Fcall_process): Check for size overflow when
14373 calculating size of args2.
14374 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14375 Normally we prefer signed values, but sticking with ptrdiff_t would
14376 require adding more-complicated checks.
14378 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14379 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14380 Redo buffer-overflow calculations to avoid integer overflow.
14381 Add a FIXME comment where memory seems to be over-allocated.
14383 * character.c (Fstring): Check for size-calculation overflow.
14385 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14386 unnecessary integer overflow. Check for size overflow.
14387 (encode_coding_object): Don't update size until xmalloc succeeds.
14389 * composite.c (get_composition_id): Check for overflow in glyph
14390 length calculations.
14392 Integer and memory overflow fixes for display code.
14393 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14394 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14395 (scrolling_window): Check for overflow in size calculations.

14402 * fns.c (concat): Check for overflow in size calculations.
14403 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14404 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

14407 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14408 (get_doc_string): Check for size calculation overflow.
14409 Don't update size until allocation succeeds.
14410 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14411 EMACS_INT, where ptrdiff_t will do.
14412 (Fsubstitute_command_keys): Check for string overflow.
14414 * editfns.c (set_time_zone_rule): Don't assume environment length
14416 (message_length): Now ptrdiff_t, not int.
14417 (Fmessage_box): Don't update size until allocation succeeds.
14418 Don't assume message length fits in int.
14419 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14421 * emacs.c (main): Do not reallocate argv, since there is a null at
14422 the end that can be overwritten, and this way there's no need to
14423 worry about size-calculation overflow.
14424 (sort_args): Check for size-calculation overflow.
14426 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14428 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14430 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14431 (x_set_scroll_bar_width, x_figure_window_size):
14432 Check for integer overflow.
14433 (x_set_alpha): Do not assume XINT fits in int.
14435 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14436 This is for the members text_lines, text_cols, total_lines, total_cols,
14437 where the system imposes an 'int' limit.
14439 * fringe.c (Fdefine_fringe_bitmap):
14440 Don't update size until alloc works.
14442 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14443 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14445 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14446 Check for size-calculation overflow.
14447 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14448 do, as we prefer signed integers.
14449 (id_to_widget.max_size, id_to_widget.used)
14450 (xg_store_widget_in_map, xg_remove_widget_from_map)
14451 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14452 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14453 Use and return ptrdiff_t, not int.
14454 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14455 * gtkutil.h: Change prototypes to match the above.
14457 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14458 are duplicate now that they've been promoted to lisp.h.
14459 (x_allocate_bitmap_record, x_alloc_image_color)
14460 (make_image_cache, cache_image, xpm_load):
14461 Don't update size until alloc is done.

14465 (ct_colors_allocated_max): New constant.
14466 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

14472 Use ptrdiff_t, not int, to count maps.
14473 (read_char_minibuf_menu_prompt): Check for overflow in size
14474 calculations. Don't update size until allocation succeeds.
14475 Redo calculations to avoid overflow.
14476 * keyboard.h: Change prototypes to match the above.
14478 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
14480 (current_minor_maps): Check for size calculation overflow.
14481 * keymap.h: Change prototypes to match the above.
14483 * lread.c (read1, init_obarray): Don't update size until alloc done.
14485 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

14488 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
14489 Now ptrdiff_t, not int.
14490 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

14502 (Fset_match_data): Don't assume list lengths fit in 'int'.
14504 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14505 for command line length. Do not attempt to address one before the
14506 beginning of an array, as that's not portable.
14508 * term.c (max_frame_lines): Remove; unused.
14509 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14511 (encode_terminal_code, calculate_costs): Check for size
14512 calculation overflow.

14518 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14519 subtracting pointers.
14520 (gobble_line): Check for overflow more carefully. Don't update size
14523 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
14524 Don't update size until alloc done.
14525 Redo size calculations to avoid overflow.
14526 Check for size calculation overflow.

14534 Use ptrdiff_t, not int, for sizes.
14535 (Finternal_make_lisp_face, cache_face):
14536 Check for size calculation overflow.
14537 (cache_face): Treat size calculation overflows as if they were
14538 memory exhaustion (the usual treatment), rather than aborting.
14540 * xfns.c (x_encode_text, x_set_name_internal)
14541 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14542 sizes, since they can exceed INT_MAX in size. Check for size
14543 calculation overflow.
14545 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
14546 (xg_select): Check for size calculation overflow.
14547 Don't update size until alloc done.
14549 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14550 as sprintf is limited to int lengths.
14552 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14553 (X_LONG_MIN): New macros.
14554 Use them to make the following changes clearer.
14555 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14556 This change doesn't affect the value now, but it may help remind
14557 future maintainers not to raise the value too much later.
14558 (SELECTION_QUANTUM): Remove, replacing with ...
14559 (selection_quantum): ... new function, which avoids overflow.
14561 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14562 assumption that selection length fits in 'int'.
14563 (x_reply_selection_request, x_handle_selection_request)
14564 (x_get_window_property, receive_incremental_selection)
14565 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
14566 (lisp_data_to_selection_data, clean_local_selection_data):
14567 Use ptrdiff_t, not int, to record length of selection.
14568 (x_reply_selection_request, x_get_window_property)
14569 (receive_incremental_selection, x_property_data_to_lisp):
14570 Redo calculations to avoid overflow.
14571 (x_reply_selection_request): When sending hint, ceiling it at

14574 (x_get_window_property, receive_incremental_selection)
14575 (lisp_data_to_selection_data, x_property_data_to_lisp):
14576 Check for size-calculation overflow.
14577 (x_get_window_property, receive_incremental_selection)
14578 (lisp_data_to_selection_data, Fx_register_dnd_atom):
14579 Don't store size until memory allocation succeeds.
14580 (x_get_window_property): Plug memory leak on memory exhaustion.
14581 Don't double-block input; malloc is safe here. Don't assume 2**34
14582 - 4 fits in unsigned long. Add an xassert to check
14583 XGetWindowProperty overflow. Be more careful about overflow
14584 calculations, and distinguish size from memory overflow better.
14585 (receive_incremental_selection): When tracing, don't assume
14586 unsigned int is less than INT_MAX.
14587 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14588 harmful) conversions of unsigned short to int.
14589 (lisp_data_to_selection_data): Don't assume that integers
14590 in the range -65535 through -1 fit in an X unsigned short.
14591 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14592 result parameters unless successful. Rely on cons_to_unsigned
14593 to report problems with elements; the old code wasn't right anyway.
14594 (x_check_property_data): Check for int overflow; we cannot use
14595 a wider type due to X limits.
14596 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
14598 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
14600 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
14601 (x_term_init): Check for size calculation overflow.
14602 (x_color_cells): Don't store size until memory allocation succeeds.
14603 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
14604 Don't assume alloca size is less than MAX_ALLOCA.
14605 (x_term_init): Don't assume length fits in int (sprintf is limited
14608 Use ptrdiff_t for composition IDs.

14627 * image.c (xpm_get_color_table_h):
14628 * lisp.h (hash_lookup, hash_put):
14629 * minibuf.c (Ftest_completion):
14630 Use ptrdiff_t for hash table indexes, not int (which is too
14631 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14632 32-bit --with-wide-int hosts).
14634 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14635 Add a FIXME comment about memory leaks.
14636 (syms_of_charset): Don't assume xmalloc returns.
14638 Don't assume that stated character widths fit in int.
14639 * character.c (Fchar_width, c_string_width, lisp_string_width):
14640 * character.h (CHAR_WIDTH):
14641 * indent.c (MULTIBYTE_BYTES_WIDTH):
14642 Use sanitize_char_width to avoid undefined and/or bad behavior
14643 with outlandish widths.
14644 * character.h (sanitize_tab_width): Rename from sanitize_width,
14645 now that we have two such functions. All uses changed.
14646 (sanitize_char_width): New inline function.
14648 Don't assume that tab-width fits in int.
14649 * character.h (sanitize_width): New inline function.
14650 (SANE_TAB_WIDTH): New macro.
14651 (ASCII_CHAR_WIDTH): Use it.
14652 * indent.c (sane_tab_width): Remove. All uses replaced by
14653 SANE_TAB_WIDTH (current_buffer).

14656 * fileio.c: Integer overflow issues with file modes.
14657 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
14659 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
14660 Remove unreachable code.

14663 * xterm.c: Don't go over XClientMessageEvent limit.
14664 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14665 (x_send_scroll_bar_event): Likewise. Check that the size does not
14666 exceed limits imposed by XClientMessageEvent, as well as the usual
14667 ptrdiff_t and size_t limits.
14669 * keyboard.c: Overflow, signedness and related fixes.
14670 (make_lispy_movement): Use same integer type in forward decl
14671 that is used in the definition.
14672 (read_key_sequence, keyremap_step):
14673 Change bufsize argument back to int, undoing my 2011-03-30 change.
14674 We prefer signed types, and int is wide enough here.
14675 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14676 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14677 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14678 length, not size_t. Use ptrdiff_t for index, not int.
14679 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14680 possibility of integer overflow.
14682 Overflow, signedness and related fixes for images.
14684 * dispextern.h (struct it.stack[0].u.image.image_id)
14685 (struct_it.image_id, struct image.id, struct image_cache.size)
14686 (struct image_cache.used, struct image_cache.ref_count):

14691 * nsmenu.m (update_frame_tool_bar):
14692 * xdisp.c (calc_pixel_width_or_height):
14693 * xfns.c (image_cache_refcount):
14694 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
14695 on typical 64-bit hosts.

14703 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
14704 (lookup_image): Remove unnecessary tests.
14705 (xbm_image_p): Locals are now of int, not EMACS_INT,
14706 since parse_image_check makes sure they fit into int.
14707 (png_load, gif_load, svg_load_image):
14708 Prefer int to unsigned where either will do.
14709 (tiff_handler): New function, combining the cores of the
14710 old tiff_error_handler and tiff_warning_handler.
14711 This function is rewritten to use vsnprintf and thereby avoid
14712 stack buffer overflows. It uses only the features of vsnprintf
14713 that are common to both POSIX and native Microsoft.
14714 (tiff_error_handler, tiff_warning_handler): Use it.
14715 (tiff_load, gif_load, imagemagick_load_image):
14716 Don't assume :index value fits in 'int'.

14794 * xdisp.c (redisplay_window): When computing centering_position,
14795 account for the height of the header line. (Bug#8874)
14797 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14798 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14799 candidate is selected by the mouse, and that candidate has a
14800 composed character under the mouse.
14802 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14803 coordinates reported by pos-visible-in-window-p for a composed

14814 composed buffer positions.
14816 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14818 * image.c (gif_load): Don't assume that each subimage has the same
14819 dimensions as the base image. Handle disposal method that is
14820 "undefined" by the gif spec (Bug#9335).

14830 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14831 from an Org mode buffer to a Speedbar frame.
14833 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14834 a composition, take its buffer position from IT->cmp_it.charpos.
14835 Fixes cursor positioning at the beginning of a line that begins
14836 with a composed character.
14838 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14840 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14841 character bidirectional type, use STRONG_L instead. Fixes crashes
14842 in a buffer produced by `describe-categories'.
14844 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14845 members before the level stack, so they would be saved and
14846 restored when copying iterator state. Fixes incorrect reordering
14847 around TABs covered by display properties.

15192 accommodate underlining, etc.
15194 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15196 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15199 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15201 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15202 Without this fix, if a signal arrives just after memory fills up,
15203 'malloc' might be invoked reentrantly.
15205 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15206 In other words, assume that every image size is allowed, on non-X
15207 hosts. This assumption is probably wrong, but it lets Emacs compile.
15209 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15211 * regex.c (re_iswctype): Convert return values to boolean.
15213 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15215 * xdisp.c (compute_display_string_pos): Don't use cached display
15216 string position if the buffer had its restriction changed.
15219 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15221 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15223 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15225 Integer signedness and overflow and related fixes. (Bug#9079)
15227 * bidi.c: Integer size and overflow fixes.
15228 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15229 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15230 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15231 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15232 (bidi_find_other_level_edge):
15233 Use ptrdiff_t instead of EMACS_INT where either will do.
15234 This works better on 32-bit hosts configured --with-wide-int.
15235 (bidi_cache_ensure_space): Check for size-calculation overflow.
15236 Use % rather than repeated addition, for better worst-case speed.
15237 Don't set bidi_cache_size until after xrealloc returns, because it
15239 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15240 (bidi_cache_ensure_space): Also check that the bidi cache size
15241 does not exceed that of the largest Lisp string or buffer. See Eli
15242 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15244 * alloc.c (__malloc_size_t): Remove.
15245 All uses replaced by size_t. See Andreas Schwab's note
15246 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15248 * image.c: Improve checking for integer overflow.
15249 (check_image_size): Assume that f is nonnull, since
15250 it is always nonnull in practice. This is one less thing to
15251 worry about when checking for integer overflow later.
15252 (x_check_image_size): New function, which checks for integer
15253 overflow issues inside X.
15254 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15255 This removes the need for a memory_full check.
15256 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15257 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15258 (xbm_read_bitmap_data): Change locals back to 'int', since
15259 their values must fit in 'int'.
15260 (xpm_load_image, png_load, tiff_load):
15261 Invoke x_create_x_image_and_pixmap earlier,
15262 to avoid much needless work if the image is too large.
15263 (tiff_load): Treat overly large images as if
15264 x_create_x_image_and_pixmap failed, not as malloc failures.
15265 (gs_load): Use x_check_image_size.
15267 * gtkutil.c: Omit integer casts.
15268 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15269 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15271 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15273 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15274 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15275 would wrongly return t on a 64-bit host.
15277 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15278 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15279 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15280 and therefore cause GCC to emit a bogus diagnostic in some cases.
15282 * image.c: Integer signedness and overflow and related fixes.
15283 This is not an exhaustive set of fixes, but it's time to
15284 record what I've got.
15285 (lookup_pixel_color, check_image_size): Remove redundant decls.
15286 (check_image_size): Don't assume that arbitrary EMACS_INT values
15287 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15288 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15289 (tiff_load, imagemagick_load_image):
15290 Check for overflow in size calculations.
15291 (x_create_x_image_and_pixmap): Remove unnecessary test for
15292 xmalloc returning NULL; that can't happen.
15293 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15294 (xpm_color_bucket): Use better integer hashing function.
15295 (xpm_cache_color): Don't possibly over-allocate memory.
15296 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15297 (gif_memory_source):
15298 Use ptrdiff_t, not int or size_t, to record sizes.
15299 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15300 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15301 either works, as we prefer signed integers.
15302 (tiff_read_from_memory, tiff_write_from_memory):
15303 Return tsize_t, not size_t, since that's what the TIFF API wants.
15304 (tiff_read_from_memory): Don't fail simply because the read would
15305 go past EOF; instead, return a short read.
15306 (tiff_load): Omit no-longer-needed casts.
15307 (Fimagemagick_types): Don't assume size fits into 'int'.
15309 Improve hashing quality when configured --with-wide-int.
15310 * fns.c (hash_string): New function, taken from sxhash_string.
15311 Do not discard information about ASCII character case; this
15312 discarding is no longer needed.
15313 (sxhash-string): Use it. Change sig to match it. Caller changed.
15314 * lisp.h: Declare it.
15315 * lread.c (hash_string): Remove, since we now use fns.c's version.
15316 The fns.c version returns a wider integer if --with-wide-int is
15317 specified, so this should help the quality of the hashing a bit.
15319 * emacs.c: Integer overflow minor fix.
15320 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15321 Define only if GNU_LINUX.
15322 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15324 * dispnew.c: Integer signedness and overflow fixes.
15325 Remove unnecessary forward decls, that were a maintenance hassle.
15326 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15328 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15329 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15330 (prepare_desired_row, line_draw_cost):
15331 Use int, not unsigned, where either works.
15332 (save_current_matrix, restore_current_matrix):
15333 Use ptrdiff_t, not size_t, where either works.
15334 (init_display): Check for overflow more accurately, and without
15335 relying on undefined behavior.
15337 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15338 Remove, replacing with the new symbols in lisp.h. All uses changed.
15339 * fileio.c (make_temp_name):
15340 * filelock.c (lock_file_1, lock_file):
15341 * xdisp.c (message_dolog):
15342 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15343 Use pMd etc. instead.
15344 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15345 replacing the pWIDE etc. symbols removed from editfns.c.
15347 * keyboard.h (num_input_events): Now uintmax_t.
15348 This is (very slightly) less likely to mess up due to wraparound.
15351 * buffer.c: Integer signedness fixes.
15352 (alloc_buffer_text, enlarge_buffer_text):
15353 Use ptrdiff_t rather than size_t when either will do, as we prefer
15356 * alloc.c: Integer signedness and overflow fixes.
15357 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15358 (__malloc_size_t): Default to size_t, not to int.
15359 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15360 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15361 Prefer ptrdiff_t to size_t when either would do, as we prefer
15363 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15364 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15365 Now const. Initialize with values that are in range even if char
15367 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15368 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15369 These functions do the right thing with sizes > 2**32.
15370 (check_depth): Now ptrdiff_t, not int.
15371 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15372 Adjust to new way of storing sizes. Check for size overflow bugs
15374 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15375 slightly wrong anyway, as it missed one instance of
15376 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15377 (refill_memory_reserve): Omit needless cast to size_t.
15378 (mark_object_loop_halt): Mark as externally visible.
15380 * xselect.c: Integer signedness and overflow fixes.
15381 (Fx_register_dnd_atom, x_handle_dnd_message):
15382 Use ptrdiff_t, not size_t, since we prefer signed.
15383 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15384 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15385 x_dnd_atoms_size and x_dnd_atoms_length.
15387 * doprnt.c: Prefer signed to unsigned when either works.
15389 * doprnt.c (doprnt):
15391 * xdisp.c (vmessage):
15392 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15393 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15394 prefer signed arithmetic to avoid comparison confusion.
15395 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15396 but is a bit tricky.
15398 Assume freestanding C89 headers, string.h, stdlib.h.
15399 * data.c, doprnt.c, floatfns.c, print.c:
15400 Include float.h unconditionally.
15401 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15402 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15403 * regex.c: Likewise for stddef.h, string.h.
15404 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15405 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15406 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15407 (STDC_HEADERS): Remove obsolete defines.
15408 * sysdep.c: Include limits.h unconditionally.
15410 Assume support for memcmp, memcpy, memmove, memset.
15411 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15412 * regex.c (memcmp, memcpy):
15413 Remove; we assume C89 now.
15415 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15416 (__malloc_safe_bcopy): Remove; no longer needed.
15418 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15419 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15420 well either way, and we prefer signed to unsigned.
15422 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15424 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15425 closes the connection while we're reading (bug#9182).
15427 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15429 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15430 are specified (Bug#9168).
15432 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15434 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15435 Found by GCC static checking and --with-wide-int on a 32-bit host.
15437 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15439 * xdisp.c (compute_display_string_pos): Fix logic of caching
15440 previous display string position. Initialize cached_prev_pos to
15441 -1. Fixes slow-down at the beginning of a buffer.
15443 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15445 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15446 for attrs[LFACE_FONTSET_INDEX].
15448 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15450 * xml.c (parse_region): Remove unused local
15451 that was recently introduced.
15453 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15455 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15456 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15458 * xdisp.c (move_it_in_display_line_to): Record the best matching
15459 position for TO_CHARPOS while scanning the line, and restore it on
15460 exit if none of the characters scanned was an exact match.
15461 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15462 when exact match is impossible due to invisible text, and the
15463 lines are truncated.
15465 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15467 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15470 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15472 Fix a significant slow-down of cursor motion with C-n, C-p,
15473 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15474 auto-repeat under bidi redisplay in fontified buffers.
15475 * xdisp.c (compute_stop_pos_backwards): New function.
15476 (next_element_from_buffer): Call compute_stop_pos_backwards to
15477 find a suitable prev_stop when we find ourselves before
15479 (reseat): Don't look for prev_stop, as that could mean a very long
15481 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15482 <cached_disp_overlay_modiff>: Cache for last found display string
15484 (compute_display_string_pos): Return the cached position if asked
15485 about the same buffer in the same area of character positions, and
15486 the buffer wasn't changed since the time the display string
15487 position was cached.
15489 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15491 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15492 is an integer, which is important for empty lines. (Bug#9149)
15494 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15496 * frame.c (Fmodify_frame_parameters): In tty case, update the
15497 default face if necessary (Bug#4238).
15499 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15501 * editfns.c (Fstring_to_char): No need to explain what a character
15502 is in the docstring (Bug#6576).
15504 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15506 * xml.c (parse_region): Make sure we always return a tree.
15508 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15510 * xml.c (parse_region): If a document contains only comments,
15513 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15515 * xml.c (make_dom): Return comments, too.
15517 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15520 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15521 and the surrounding thread.
15522 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15523 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15524 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15526 * s/openbsd.h (BROKEN_SIGIO): Define.
15527 * unexelf.c (unexec) [__OpenBSD__]:
15528 Don't update the .mdebug section of the Alpha COFF symbol table.
15530 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15532 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15535 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15537 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15538 This fixes some race conditions on the permissions of any newly
15541 * alloc.c (valid_pointer_p): Use pipe, not open.
15542 This fixes some permissions issues when debugging.
15544 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15545 If fchown fails to set both uid and gid, try to set just gid,
15546 as that is sometimes allowed. Adjust the file's mode to eliminate
15547 setuid or setgid bits that are inappropriate if fchown fails.
15549 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15551 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15552 to compare Lisp_Objects.
15553 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15554 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15555 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15557 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15559 * lread.c (read_integer): Unread even EOF character.
15560 (read1): Likewise. Properly record start position of symbol.
15562 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15563 symbol character follows.
15565 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15567 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15568 This works around a problem with the previous change to Fcopy_file.
15569 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15570 and without this change, GCC might complain about discarding
15571 fchown's return value.
15573 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15575 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15577 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15579 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15581 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15583 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15584 it's used from the C level.
15586 * process.c: Use the same condition for POLL_FOR_INPUT in both
15587 keyboard.c and process.c (bug#1858).
15589 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15591 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15592 (Fgnutls_boot): Use it.
15594 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15596 * doc.c (Fsubstitute_command_keys): Revert last change.
15598 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15600 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15601 quotes the next character, and doesn't affect other longer
15602 sequences (bug#8935).
15604 * lread.c (syms_of_lread): Clarify that is isn't only
15605 `eval-buffer' and `eval-defun' that's affected by
15606 `lexical-binding' (bug#8460).
15608 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15610 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15611 bidi redisplay when a line includes both an image and is truncated.
15613 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15615 Fix minor problems found by static checking.
15616 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15617 (elsz): Now a signed constant, not a size_t var. We prefer signed
15618 types to unsigned, to avoid integer comparison confusion. Without
15619 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15620 "cannot optimize loop, the loop counter may overflow", a symptom
15622 * indent.c (Fvertical_motion): Mark locals as initialized.
15623 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15625 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15627 * search.c (Fre_search_backward): Mention `case-fold-search' in
15628 all the re_search_* functions (bug#8138).
15630 * keyboard.c (Fopen_dribble_file): Document when the file is
15633 2011-07-14 Eli Zaretskii <eliz@gnu.org>

16147 (clone_per_buffer_values): Don't assume that

16149 This isn't true in general, and it's particularly not true
16150 if Emacs is configured with --with-wide-int.
16151 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16152 New macros, used in the buffer.c change.

16188 Random fixes. E.g., (random) never returned negative values.
16189 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16190 subseconds part to the entropy, as that's a bit more random.
16191 Prefer signed to unsigned, since the signedness doesn't matter and
16192 in general we prefer signed. When given a limit, use a
16193 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16194 latter isn't right if USE_2_TAGS_FOR_INTS.
16195 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16196 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16208 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16209 This is more efficient than Ffile_directory_p and avoids a minor race.

16213 * buffer.c (Foverlay_put): Say what the return value is
16216 * fileio.c (barf_or_query_if_file_exists): Check first if the file

16220 error be more correct.
16222 * fns.c (Frequire): Remove the mention of the .gz files, since
16223 that's installation-specific, but keep the mention of
16224 `get-load-suffixes'.

16236 Qgnutls_bootprop_verify_error (which is no longer used).
16238 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16239 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16240 Also (re)move comments that are misplaced or no longer relevant.
16242 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16244 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16269 * lread.c (syms_of_lread): Mention single symbols defined by

16341 * eval.c (struct backtrace): Simplify and port the data structure.
16342 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16343 signed bit field, as this assumption is not portable and it makes
16344 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16345 "char debug_on_exit : 1" as this is not portable either; instead,
16346 use the portable "unsigned int debug_on_exit : 1". Remove unused
16347 member evalargs. Remove obsolete comments about cc bombing out.
16349 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16511 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16513 Integer and buffer overflow fixes (Bug#8873).
16515 * print.c (printchar, strout): Check for string overflow.
16516 (PRINTPREPARE, printchar, strout):
16517 Don't set size unless allocation succeeds.
16519 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16520 for sizes. Check for string overflow more accurately.
16521 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16523 * macros.c: Integer and buffer overflow fixes.
16524 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16525 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
16526 Use ptrdiff_t, not int, for sizes.
16527 Don't increment bufsize until after realloc succeeds.
16528 Check for size-calculation overflow.
16529 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16531 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16533 * lread.c: Integer overflow fixes.
16534 (read_integer): Radix is now EMACS_INT, not int,
16535 to improve quality of diagnostics for out-of-range radices.
16536 Calculate buffer size correctly for out-of-range radices.
16537 (read1): Check for integer overflow in radices, and in
16538 read-circle numbers.
16539 (read_escape): Avoid int overflow.
16540 (Fload, openp, read_buffer_size, read1)
16541 (substitute_object_recurse, read_vector, read_list, map_obarray):
16542 Use ptrdiff_t, not int, for sizes.
16543 (read1): Use EMACS_INT, not int, for sizes.
16544 Check for size overflow.
16546 * image.c (cache_image): Check for size arithmetic overflow.
16548 * lread.c: Integer overflow issues.
16549 (saved_doc_string_size, saved_doc_string_length)
16550 (prev_saved_doc_string_size, prev_saved_doc_string_length):
16551 Now ptrdiff_t, not int.
16552 (read1): Don't assume doc string length fits in int. Check for

16555 (read_escape): Check for hex character overflow.
16557 2011-06-22 Leo Liu <sdl.web@gmail.com>
16559 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16560 Move to minibuffer.el.
16562 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16564 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16565 The following patches are for when GLYPH_DEBUG && !XASSERT.
16566 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16567 * dispnew.c (flush_stdout):
16568 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16569 Mark as externally visible.
16570 * dispnew.c (check_window_matrix_pointers): Now static.
16571 * dispnew.c (window_to_frame_vpos):
16572 * xfns.c (unwind_create_frame):
16573 * xterm.c (x_check_font): Remove unused local.
16574 * scroll.c (CHECK_BOUNDS):
16575 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16576 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16577 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16578 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16579 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16581 (debug_method_add): Use va_list and vsprintf rather than relying
16582 on undefined behavior with wrong number of arguments.
16583 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16584 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16585 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16586 since we're not interested in debugging glyphs with old libraries.
16587 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16588 GCC 4.6.0's static checking.
16590 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16592 Integer overflow and signedness fixes (Bug#8873).

16601 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16602 (x_create_bitmap_from_xpm_data):
16603 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16604 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16606 * xfaces.c (load_pixmap):
16607 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16608 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16609 (.bitmaps_last, struct x_output.icon_bitmap):
16610 Use ptrdiff_t, not int, for bitmap indexes.
16611 (x_allocate_bitmap_record): Check for size overflow.
16612 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16614 Use ptrdiff_t, not int, for overlay counts.
16615 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16616 * editfns.c (overlays_around, get_pos_property):
16617 * textprop.c (get_char_property_and_overlay):
16618 * xdisp.c (next_overlay_change, note_mouse_highlight):
16619 * xfaces.c (face_at_buffer_position):
16620 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16621 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16622 (Fnext_overlay_change, Fprevious_overlay_change)
16623 (mouse_face_overlay_overlaps, Foverlays_in):
16624 Use ptrdiff_t, not int, for sizes.
16625 (overlays_at, overlays_in): Check for size-calculation overflow.
16627 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16629 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16630 (x_session_initialize): Do not assume string length fits in int.
16632 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16633 This is unlikely, but can occur if DPI is outlandish.
16635 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16636 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16638 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16639 * xrdb.c (magic_file_p, search_magic_path):
16640 Omit last arg SUFFIX; it was always 0. All callers changed.
16641 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16643 * xfont.c (xfont_match): Avoid need for strlen.
16645 * xfns.c: Don't assume strlen fits in int.
16646 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16648 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16649 not unsigned long, as we prefer signed integers. All callers changed.
16650 Detect integer overflow in repeat count.
16651 (message_dolog): Don't assume print length fits in 39 bytes.
16652 (display_mode_element): Don't assume strlen fits in int.
16654 * termcap.c: Don't assume sizes fit in int and never overflow.
16655 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16656 (gobble_line): Check for size-calculation overflow.
16658 * minibuf.c (Fread_buffer):
16659 * lread.c (intern, intern_c_string):
16660 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16661 Don't assume string length fits in int.
16663 * keyboard.c (parse_tool_bar_item):
16664 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16666 * font.c: Don't assume string length fits in int.
16667 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16668 Use ptrdiff_t, not int.
16669 (font_intern_prop): Don't assume string length fits in int.
16670 Don't assume integer property fits in fixnum.
16671 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16673 * filelock.c: Fix some buffer overrun and integer overflow issues.
16674 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16675 Reformulate so as not to need the command string.
16676 Invoke gzip -cd rather than gunzip, as it's more portable.
16677 (lock_info_type, lock_file_1, lock_file):
16678 Don't assume pid_t and time_t fit in unsigned long.
16679 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16680 (current_lock_owner): Prefer signed type for sizes.
16681 Use memcpy, not strncpy, where memcpy is what is really wanted.
16682 Don't assume (via atoi) that time_t and pid_t fit in int.
16683 Check for time_t and/or pid_t out of range, e.g., via a network share.
16684 Don't alloca where an auto var works fine.
16686 * fileio.c: Fix some integer overflow issues.
16687 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16688 Don't assume string length fits in int.
16689 (directory_file_name): Don't assume string length fits in long.
16690 (make_temp_name): Don't assume pid fits in int, or that its print
16691 length is less than 20.
16693 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16695 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16697 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16699 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16700 We prefer signed integers, even for size calculations.
16702 * emacs.c: Don't assume string length fits in 'int'.
16703 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16704 (main): Don't invoke strlen when not needed.
16706 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16707 (XD_DEBUG_MESSAGE): Don't waste a byte.
16709 * callproc.c (getenv_internal_1, getenv_internal)
16710 (Fgetenv_internal):
16711 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16713 * lread.c (invalid_syntax): Omit length argument.
16714 All uses changed. This doesn't fix a bug, but it simplifies the
16715 code away from its former Hollerith-constant appearance, and it's
16716 one less 'int' to worry about when looking at integer-overflow issues.
16717 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16719 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16720 This didn't break anything, but it didn't help either.
16721 It's confusing to put a bogus integer in a place where the actual
16722 value does not matter.
16723 (LIST_END_P): Remove unused macro and its bogus comment.
16724 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16726 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16727 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16729 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16730 We prefer signed types, and the value cannot exceed the EMACS_INT
16731 range anyway (because otherwise the length would not be representable).
16732 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16733 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16734 This avoids a GCC warning when WIDE_EMACS_INT.
16736 * indent.c (sane_tab_width): New function.
16737 (current_column, scan_for_column, Findent_to, position_indentation)
16738 (compute_motion): Use it. This is just for clarity.
16739 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16741 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16743 * lisp.h (lint_assume): New macro.
16744 * composite.c (composition_gstring_put_cache):
16745 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16747 * editfns.c, insdel.c:
16748 Omit unnecessary forward decls, to simplify future changes.
16750 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16752 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16754 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16755 Use much-faster test for byte-length change.
16756 Don't assume string byte-length fits in 'int'.
16757 Check that character arg fits in 'int'.
16758 (mapcar1): Declare byte as byte, for clarity.
16760 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16762 * fns.c (concat): Catch string overflow earlier.
16763 Do not rely on integer wraparound.
16765 * dispextern.h (struct it.overlay_strings_charpos)
16766 (struct it.selective): Now EMACS_INT, not int.
16767 * xdisp.c (forward_to_next_line_start)
16768 (back_to_previous_visible_line_start)
16769 (reseat_at_next_visible_line_start, next_element_from_buffer):
16770 Don't arbitrarily truncate the value of 'selective' to int.
16772 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16774 * composite.c: Don't truncate sizes to 'int'.
16775 (composition_gstring_p, composition_reseat_it)
16776 (composition_adjust_point): Use EMACS_INT, not int.
16777 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16778 not EMACS_UINT, for indexes.
16780 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16782 * buffer.c: Include <verify.h>.
16783 (struct sortvec.priority, struct sortstr.priority):
16784 Now EMACS_INT, not int.
16785 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16786 (struct sortstr.size, record_overlay_string)
16787 (struct sortstrlist.size, struct sortlist.used):
16788 Don't truncate size to int.
16789 (record_overlay_string): Check for size-calculation overflow.
16790 (init_buffer_once): Check at compile-time, not run-time.
16792 2011-06-22 Jim Meyering <meyering@redhat.com>
16794 Don't leak an XBM-image-sized buffer
16795 * image.c (xbm_load): Free the image buffer after using it.
16797 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16800 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16801 that Sun C diagnosed.
16802 * fns.c (secure_hash): Fix pointer signedness issue.
16803 * intervals.c (static_offset_intervals): New function.
16804 (offset_intervals): Use it.
16806 2011-06-21 Leo Liu <sdl.web@gmail.com>
16809 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16812 * fns.c (secure_hash): Rename from crypto_hash_function and change
16813 the first arg to accept symbols.
16814 (Fsecure_hash): New primitive.
16815 (syms_of_fns): New symbols.
16817 2011-06-20 Deniz Dogan <deniz@dogan.se>
16819 * process.c (Fset_process_buffer): Clarify return value in
16822 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16824 * dispnew.c (add_window_display_history): Use BVAR.
16826 * xdisp.c (debug_method_add): Use BVAR.
16827 (check_window_end, dump_glyph_matrix, dump_glyph)
16828 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16830 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16833 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16834 check till after the cache is created in init_frame_faces.
16836 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16838 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16840 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16842 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16843 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16844 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16846 Improve buffer-overflow checking (Bug#8873).
16847 * fileio.c (Finsert_file_contents):
16848 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16849 Remove the old (too-loose) buffer overflow checks.
16850 They weren't needed, since make_gap checks for buffer overflow.
16851 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16852 The old code merely checked for Emacs fixnum overflow, and relied
16853 on undefined (wraparound) behavior. The new code avoids undefined
16854 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16856 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16857 Tune. Don't use wider integers than needed. Don't use alloca.
16858 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16860 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16862 * insdel.c, lisp.h (buffer_overflow): New function.
16863 (insert_from_buffer_1, replace_range, replace_range_2):
16864 * insdel.c (make_gap_larger):
16865 * editfns.c (Finsert_char):
16866 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16868 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16870 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16872 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16874 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16875 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16877 * fileio.c: Don't assume EMACS_INT fits in off_t.
16878 (emacs_lseek): New static function.
16879 (Finsert_file_contents, Fwrite_region): Use it.
16880 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16882 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16884 * fns.c: Don't overflow int when computing a list length.
16885 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16886 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16887 truncation on 64-bit hosts. Check for QUIT every
16888 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16889 faster and is responsive enough.
16890 (Flength): Report an error instead of overflowing an integer.
16891 (Fsafe_length): Return a float if the value is not representable
16892 as a fixnum. This shouldn't happen except in contrived situations.
16893 (Fnthcdr, Fsort): Don't assume list length fits in int.
16894 (Fcopy_sequence): Don't assume vector length fits in int.
16896 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16897 (header_size, word_size): New constants.
16898 (allocate_vectorlike): Don't check size overflow here.
16899 (allocate_vector): Check it here instead, since this is the only
16900 caller of allocate_vectorlike that could cause overflow.
16901 Check that the new vector's length is representable as a fixnum.
16903 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16904 The previous code was bogus. For example, next_almost_prime (32)
16905 returned 39, which is undesirable as it is a multiple of 3; and
16906 next_almost_prime (24) returned 25, which is a multiple of 5 so
16907 why was the code bothering to check for multiples of 7?
16909 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16911 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16913 Variadic C functions now count arguments with ptrdiff_t.
16914 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16915 Back then I didn't know that the Emacs coding style prefers signed int.
16916 Also, in the meantime I found a few more instances where arguments
16917 were being counted with int, which may truncate counts on 64-bit
16918 machines, or EMACS_INT, which may be unnecessarily wide.
16919 * lisp.h (struct Lisp_Subr.function.aMANY)
16920 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16921 Arg counts are now ptrdiff_t, not size_t.
16922 All variadic functions and their callers changed accordingly.
16923 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16924 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16925 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16926 * callint.c (Fcall_interactively): Check arg count for overflow,
16927 to avoid potential buffer overrun. Use signed char, not 'int',
16928 for 'varies' array, so that we needn't bother to check its size
16929 calculation for overflow.
16930 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16931 * eval.c (apply_lambda):
16932 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16933 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16934 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16936 * callint.c (Fcall_interactively): Don't use index var as event count.
16938 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16939 * mem-limits.h (SIZE): Remove; no longer used.
16941 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16943 Remove unnecessary casts.
16944 * xterm.c (x_term_init):
16945 * xfns.c (x_set_border_pixel):
16946 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16947 These aren't needed now that we assume ANSI C.
16949 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16950 It's more likely to cause problems (due to unsigned overflow)
16953 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16955 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16957 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16959 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16961 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16963 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16965 GLYPH_CODE_FACE returns EMACS_INT, not int.
16966 * dispextern.h (merge_faces):
16967 * xfaces.c (merge_faces):
16968 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16969 Don't assume EMACS_INT fits in int.
16971 * character.h (CHAR_VALID_P): Remove unused parameter.
16972 * fontset.c, lisp.h, xdisp.c: All uses changed.
16974 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16976 * fns.c (concat): Minor tuning based on overflow analysis.
16977 This doesn't fix any bugs. Use int to hold character, instead
16978 of constantly refetching from Emacs object. Use XFASTINT, not
16979 XINT, for value known to be a character. Don't bother comparing
16980 a single byte to 0400, as it's always less.
16982 * floatfns.c (Fexpt):
16983 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16985 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16988 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16990 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16991 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16992 incorrectly succeed when S was a string, because 4294967386 was
16993 truncated before it was used.
16995 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16996 Otherwise, an out-of-range integer could cause undefined behavior
16999 * composite.c: Use int, not EMACS_INT, for characters.
17000 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17001 EMACS_INT, for values that are known to be in character range.
17002 This doesn't fix any bugs but is the usual style inside Emacs and
17003 may generate better code on 32-bit machines.
17005 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17006 This is for reasons similar to the recent CHAR_STRING fix.
17007 * charset.c (Fencode_char): Check that character arg is actually
17008 a character. Pass an int to ENCODE_CHAR.
17009 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17010 wider than 'int', as a compile-time check to prevent future regressions
17013 * character.c (char_string): Remove unnecessary casts.
17015 Make sure a 64-bit char is never passed to CHAR_STRING.
17016 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17017 by silently ignoring the top 32 bits, allowing some values
17018 that were far too large to be valid characters.
17019 * character.h: Include <verify.h>.
17020 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17021 arguments are no wider than unsigned, as a compile-time check
17022 to prevent future regressions in this area.
17024 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17025 (Fsubst_char_in_region):
17027 * xdisp.c (decode_mode_spec_coding):
17028 Adjust to CHAR_STRING's new requirement.
17029 * editfns.c (Finsert_char, Fsubst_char_in_region):
17030 * fns.c (concat): Check that character args are actually
17031 characters. Without this test, these functions did the wrong
17032 thing with wildly out-of-range values on 64-bit hosts.
17034 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17035 These casts should not be needed on 32-bit hosts, either.
17036 * keyboard.c (read_char):
17037 * lread.c (Fload): Remove casts to unsigned.
17039 * lisp.h (UNSIGNED_CMP): New macro.
17040 This fixes comparison bugs on 64-bit hosts.
17041 (ASCII_CHAR_P): Use it.
17042 * casefiddle.c (casify_object):
17043 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17044 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17045 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17046 * dispextern.h (FACE_FROM_ID):
17047 * keyboard.c (read_char): Use UNSIGNED_CMP.
17049 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17050 not to EMACS_INT, to avoid GCC warning.
17052 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17054 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17055 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17056 isn't needed on 32-bit machines.
17058 * buffer.c (Fgenerate_new_buffer_name):
17059 Use EMACS_INT for count, not int.
17060 (advance_to_char_boundary): Return EMACS_INT, not int.
17062 * data.c (Qcompiled_function): Now static.
17064 * window.c (window_body_lines): Now static.
17066 * image.c (gif_load): Rename local to avoid shadowing.
17068 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17069 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17070 * alloc.c (make_save_value): Integer argument is now of type
17071 ptrdiff_t, not int.
17072 (mark_object): Use ptrdiff_t, not int.
17073 * lisp.h (pD): New macro.
17074 * print.c (print_object): Use it.
17076 * alloc.c: Use EMACS_INT, not int, to count objects.
17077 (total_conses, total_markers, total_symbols, total_vector_size)
17078 (total_free_conses, total_free_markers, total_free_symbols)
17079 (total_free_floats, total_floats, total_free_intervals)
17080 (total_intervals, total_strings, total_free_strings):
17081 Now EMACS_INT, not int. All uses changed.
17082 (Fgarbage_collect): Compute overall total using a double, so that
17083 integer overflow is less likely to be a problem. Check for overflow
17084 when converting back to an integer.
17085 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17086 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17087 These were 'int' variables that could overflow on 64-bit hosts;
17088 they were never used, so remove them instead of repairing them.
17089 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17090 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17091 Previously, this ceilinged at INT_MAX, but that doesn't work on
17093 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17095 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17096 (allocate_vectorlike): Check for ptrdiff_t overflow.
17097 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17098 when a (possibly-narrower) signed value would do just as well.
17099 We prefer using signed arithmetic, to avoid comparison confusion.
17101 * alloc.c: Catch some string size overflows that we were missing.
17102 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17103 for convenience in STRING_BYTES_MAX.
17104 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17105 The definition here is exact; the one in lisp.h was approximate.
17106 (allocate_string_data): Check for string overflow. This catches
17107 some instances we weren't catching before. Also, it catches
17108 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17109 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17110 and ptrdiff_t and EMACS_INT are both 64 bits.
17112 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17113 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17114 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17116 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17118 * alloc.c (Fmake_string): Check for out-of-range init.
17120 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17122 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17124 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17126 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

17129 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17130 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17131 (style_changed_cb): Call update_theme_scrollbar_width and call
17132 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17133 all frames (Bug#8505).
17134 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17135 Call gtk_window_set_resizable if HAVE_GTK3.

17137 and height if HAVE_GTK3 (Bug#8505).
17138 (scroll_bar_width_for_theme): New variable.
17139 (update_theme_scrollbar_width): New function.
17140 (xg_get_default_scrollbar_width): Move code to
17141 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17142 (xg_initialize): Call update_theme_scrollbar_width.
17144 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17146 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17148 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17150 * frame.c (make_frame): Call other_buffer_safely instead of
17153 * window.c (temp_output_buffer_show): Call display_buffer with
17154 second argument Vtemp_buffer_show_specifiers and reset latter
17155 immediately after the call.
17156 (Vtemp_buffer_show_specifiers): New variable.
17157 (auto_window_vscroll_p, next_screen_context_lines)
17158 (Vscroll_preserve_screen_position): Remove leading asterisks from

17204 (Fset_window_configuration): Rewrite to handle dead buffers and
17205 consequently deletable windows.
17206 (window_tree, Fwindow_tree): Remove. Supply functionality in

17341 Remove static from declaration of Qdelete_window, it's
17342 temporarily needed by Fbury_buffer.
17343 (replace_window): Don't assign orig_top_line and
17345 (Fdelete_window, delete_window): Remove. Window deletion is

17347 (window_loop): Remove DELETE_OTHER_WINDOWS case.
17348 Replace Fdelete_window calls with calls to Qdelete_window.
17349 (Fdelete_other_windows): Remove. Deleting other windows is

17722 value of a `display' property is a "replacing spec".
17723 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17724 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

17754 * gnutls.c: Use Emacs's memory allocators.
17755 Without this change, the gnutls library would invoke malloc etc.
17756 directly, which causes problems on non-SYNC_INPUT hosts, and which
17757 runs afoul of improving memory_full behavior. (Bug#8761)
17758 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17759 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17760 xfree instead of the default malloc, realloc, free.
17761 (Fgnutls_boot): No need to check for memory allocation failure,
17762 since xmalloc does that for us.

17786 * alloc.c (allocate_vectorlike):
17787 Check for overflow in vector size calculations.
17788 * ccl.c (ccl_driver):
17789 Check for overflow when converting EMACS_INT to int.

17791 need to be updated by these changes.
17792 * fns.c (make_hash_table, maybe_resize_hash_table):
17793 Check for integer overflow with large hash tables.
17794 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17795 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17796 (SXHASH_REDUCE): New macro.
17797 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17798 Use it instead of discarding useful hash info with large hash values.
17799 (sxhash_float): New function.
17800 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17801 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17802 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17803 Rewrite to use FIXNUM_BITS, as this simplifies things.
17804 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17805 Adjust signatures to match updated version of code.
17806 (consing_since_gc): Now EMACS_INT, since a single hash table can
17807 use more than INT_MAX bytes.
17809 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17811 Make it possible to build with GCC-4.6+ -O2 -flto.
17813 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17815 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17817 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17818 Call minibuffer-inactive-mode.
17820 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
17822 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17823 Update dependencies.
17825 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17827 * data.c (init_data): Remove code for UTS, this system is not
17830 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17832 Don't force ./temacs to start in terminal mode.
17834 * frame.c (make_initial_frame): Initialize faces in all cases, not
17835 only when CANNOT_DUMP is defined.
17836 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17838 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17840 * dispnew.c (add_window_display_history): Use const for the string
17841 pointer. Remove declaration, not needed.
17843 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17845 Use 'inline', not 'INLINE'.
17846 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17847 * alloc.c, fontset.c (INLINE): Remove.
17848 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17849 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17850 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17851 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17852 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17854 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17856 Make it possible to run ./temacs.
17858 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17859 syms_of_callproc does the same thing. Remove test for
17860 "initialized", do it in the caller.
17861 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17863 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17865 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17866 (read_minibuf): Use get_minibuffer.
17867 (syms_of_minibuf): Use DEFSYM.
17868 (Qmetadata): New var.
17869 * data.c (Qbuffer): Don't make it static.
17870 (syms_of_data): Use DEFSYM.
17872 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17874 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17875 (CCL_CODE_MIN): New macro.
17877 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17879 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17881 * eval.c (Qdebug): Now static.
17882 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17883 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17884 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17886 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17888 * image.c: Various fixes to ImageMagick code comments.
17889 (Fimagemagick_types): Doc fix.
17891 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17893 Minor fixes prompted by GCC 4.6.0 warnings.
17895 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17897 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17898 (x_clipboard_manager_save_all): Move extern decl to ...
17899 * xterm.h: ... here, so that it can be checked for consistency.
17901 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17903 * xselect.c (x_clipboard_manager_save_frame)
17904 (x_clipboard_manager_save_all): New functions.
17905 (Fx_clipboard_manager_save): Lisp function deleted.
17907 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17908 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17910 * xterm.h: Update prototype.
17912 2011-05-28 William Xu <william.xwl@gmail.com>
17914 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17915 exiting (Bug#8239).
17917 2011-05-28 Jim Meyering <meyering@redhat.com>
17919 Avoid a sign-extension bug in crypto_hash_function.
17920 * fns.c (to_uchar): Define.
17921 (crypto_hash_function): Use it to convert some newly-signed
17922 variables to unsigned, to avoid sign-extension bugs. For example,
17923 without this change, (md5 "truc") would evaluate to
17924 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17925 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17926 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17928 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17930 Integer overflow fixes.
17932 * dbusbind.c: Serial number integer overflow fixes.
17933 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17934 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17935 to hold a serial number that is too large for a fixnum.
17936 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17937 Check for serial numbers out of range. Decode any serial number
17938 that was so large that it became a float. (Bug#8722)
17940 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17941 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17942 Use XFASTINT rather than XUINT when numbers are nonnegative.
17943 (xd_append_arg, Fdbus_method_return_internal):
17944 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17945 arguments, check that Lisp number is nonnegative, rather than
17946 silently wrapping negative numbers around. (Bug#8722)
17947 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17950 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17952 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17954 ccl: Add integer overflow checks.
17955 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17956 (IN_INT_RANGE): New macros.
17957 (ccl_driver): Use them to check for integer overflow when
17958 decoding a CCL program. Many of the new checks are whether XINT (x)
17959 fits in int; it doesn't always, on 64-bit hosts. The new version
17960 doesn't catch all possible integer overflows, but it's an
17961 improvement. (Bug#8719)
17963 * alloc.c (make_event_array): Use XINT, not XUINT.
17964 There's no need for unsigned here.
17966 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17967 This follows up to the 2011-05-06 change that substituted uintptr_t
17968 for EMACS_INT. This case wasn't caught back then.
17970 Rework Fformat to avoid integer overflow issues.
17971 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17972 now (part of C89). Include <verify.h>.
17973 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17974 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17975 (Fformat): Avoid the prepass trying to compute sizes; it was only
17976 approximate and thus did not catch overflow reliably. Instead, walk
17977 through the format just once, formatting and computing sizes as we go,
17978 checking for integer overflow at every step, and allocating a larger
17979 buffer as needed. Keep track separately whether the format is
17980 multibyte. Keep only the most-recently calculated precision, rather
17981 than them all. Record whether each argument has been converted to
17982 string. Use EMACS_INT, not int, for byte and char and arg counts.
17983 Support field widths and precisions larger than INT_MAX. Avoid
17984 sprintf's undefined behavior with conversion specifications such as %#d
17985 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17986 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17987 formatting out-of-range floating point numbers with int
17988 formats. (Bug#8668)
17990 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17992 * data.c: Avoid integer truncation in expressions involving floats.
17993 * data.c: Include <intprops.h>.
17994 (arith_driver): When there's an integer overflow in an expression
17995 involving floating point, convert the integers to floating point
17996 so that the resulting value does not suffer from catastrophic
17997 integer truncation. For example, on a 64-bit host (* 4
17998 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17999 Do not rely on undefined behavior after integer overflow.
18001 merge count_size_as_multibyte, parse_str_to_multibyte
18002 * character.c, character.h (count_size_as_multibyte):
18003 Rename from parse_str_to_multibyte; all uses changed.
18004 Check for integer overflow.
18005 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18006 since it's now a duplicate of the other. This is more of
18007 a character than a buffer op, so better that it's in character.c.
18008 * fns.c, print.c: Adjust to above changes.
18010 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18012 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18014 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18016 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18017 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18018 (x_clipboard_manager_save): Now static.
18019 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18021 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18022 (crypto_hash_function): Now static.
18023 Fix pointer signedness problems. Avoid unnecessary initializations.
18025 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18027 * termhooks.h (Vselection_alist): Make it terminal-local.
18029 * terminal.c (create_terminal): Initialize it.
18031 * xselect.c: Support for clipboard managers.
18032 (Vselection_alist): Move to termhooks.h as terminal-local var.
18033 (LOCAL_SELECTION): New macro.
18034 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18035 (symbol_to_x_atom): Remove gratuitous arg.
18036 (x_handle_selection_request, lisp_data_to_selection_data)
18037 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18038 (x_own_selection, x_get_local_selection, x_convert_selection):
18039 New arg, specifying work frame. Use terminal-local Vselection_alist.
18040 (some_frame_on_display): Delete unused function.
18041 (Fx_own_selection_internal, Fx_get_selection_internal)
18042 (Fx_disown_selection_internal, Fx_selection_owner_p)
18043 (Fx_selection_exists_p): New optional frame arg.
18044 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18045 (x_handle_selection_clear): Don't treat other terminals with the
18046 same keyboard specially. Use the terminal-local Vselection_alist.
18047 (x_clear_frame_selections): Use Frun_hook_with_args.
18049 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18051 * xterm.h: Add support for those atoms.
18053 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18055 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18056 (converted_selections, conversion_fail_tag): New global variables.
18057 (x_selection_request_lisp_error): Free the above.
18058 (x_get_local_selection): Remove unnecessary code.
18059 (x_reply_selection_request): Args changed; handle arbitrary array
18060 of converted selections stored in converted_selections.
18061 Separate the XChangeProperty and SelectionNotify steps.
18062 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18063 (x_convert_selection): New function.
18064 (x_handle_selection_event): Simplify.
18065 (x_get_foreign_selection): Don't ignore incoming requests while
18066 waiting for an answer; this will fail when we implement
18067 SAVE_TARGETS, and seems unnecessary anyway.
18068 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18069 (Vx_sent_selection_functions): Doc fix.
18071 2011-05-26 Leo Liu <sdl.web@gmail.com>
18073 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18075 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18077 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18079 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18080 for fringe update if it has periodic bitmap.
18081 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18082 and fringe_bitmap_periodic_p.
18084 * fringe.c (get_fringe_bitmap_data): New function.
18085 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18086 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18087 row. Mark glyph row for fringe update if periodicity changed.
18089 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18090 for fringe update unless it has periodic bitmap.
18092 2011-05-25 Kenichi Handa <handa@m17n.org>
18094 * xdisp.c (get_next_display_element): Set correct it->face_id for
18095 a static composition.
18097 2011-05-24 Leo Liu <sdl.web@gmail.com>
18100 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18102 * fns.c (crypto_hash_function, Fsha1): New function.
18103 (Fmd5): Use crypto_hash_function.
18104 (syms_of_fns): Add Ssha1.
18106 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18108 * gnutls.c: Remove unused macros.
18109 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18110 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18111 Remove macros that are defined and never used.
18112 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18114 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18116 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18117 (Fx_get_selection_internal): Minor cleanup.
18118 (Fx_own_selection_internal): Rename arguments for consistency with
18121 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18123 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18125 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18127 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18129 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18131 * dispnew.c (scrolling_window): Don't exclude the case that the
18132 last enabled row in the desired matrix touches the bottom boundary.
18134 2011-05-21 Glenn Morris <rgm@gnu.org>
18136 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18137 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18138 and add some more files.
18140 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18142 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18143 report_file_error introduced by the change from 2011-05-07.
18145 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18147 * systime.h (Time): Define only if emacs is defined.
18148 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18149 where the include path doesn't have X11/X.h by default. See
18150 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18152 2011-05-20 Kenichi Handa <handa@m17n.org>
18154 * composite.c (find_automatic_composition): Fix previous change.
18156 2011-05-20 Glenn Morris <rgm@gnu.org>
18158 * lisp.mk: New file, split from Makefile.in.
18159 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18160 (shortlisp): Remove.
18161 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18163 2011-05-19 Glenn Morris <rgm@gnu.org>
18165 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18166 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18167 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18168 (lisp): Set the order to that of loadup.el.
18169 (shortlisp): Make it a copy of $lisp.
18170 (SOME_MACHINE_LISP): Remove.
18171 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18172 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18174 2011-05-18 Kenichi Handa <handa@m17n.org>
18176 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18177 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18178 (find_automatic_composition): Mostly rewrite for efficiency.
18180 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18182 * makefile.w32-in: Update dependencies.
18184 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18186 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18187 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18189 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18191 Fix some integer overflow issues, such as string length overflow.
18193 * insdel.c (count_size_as_multibyte): Check for string overflow.
18195 * character.c (lisp_string_width): Check for string overflow.
18196 Use EMACS_INT, not int, for string indexes and lengths; in
18197 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18198 the resulting string length overflows an EMACS_INT; instead,
18199 report a string overflow if no precision given. When checking for
18200 precision exhaustion, use a check that cannot possibly have
18201 integer overflow. (Bug#8675)
18202 * character.h (lisp_string_width): Adjust to new signature.
18204 * alloc.c (string_overflow): New function.
18205 (Fmake_string): Use it. This doesn't change behavior, but saves
18206 a few bytes and will simplify future changes.
18207 * character.c (string_escape_byte8): Likewise.
18208 * lisp.h (string_overflow): New decl.
18210 Fixups, following up to the user-interface timestamp change.
18211 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18212 for UI timestamps, instead of unsigned long.
18213 * msdos.c (mouse_get_pos): Likewise.
18214 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18215 * w32gui.h (Time): Define by including "systime.h" rather than by
18216 declaring it ourselves. (Bug#8664)
18218 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18219 * image.c (clear_image_cache): Likewise.
18221 * term.c (term_mouse_position): Don't assume time_t wraparound.
18223 Be more systematic about user-interface timestamps.
18224 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18225 and sometimes 'EMACS_UINT', to represent these timestamps.
18226 This change causes it to use 'Time' uniformly, as that's what X uses.
18227 This makes the code easier to follow, and makes it easier to catch
18228 integer overflow bugs such as Bug#8664.
18229 * frame.c (Fmouse_position, Fmouse_pixel_position):
18230 Use Time, not unsigned long, for user-interface timestamps.
18231 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18232 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18233 * keyboard.h (last_event_timestamp): Likewise.
18234 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18235 * menu.h (xmenu_show): Likewise.
18236 * term.c (term_mouse_position): Likewise.
18237 * termhooks.h (struct input_event.timestamp): Likewise.
18238 (struct terminal.mouse_position_hook): Likewise.
18239 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18240 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18241 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18242 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18243 what it was before.
18244 * menu.h, termhooks.h: Include "systime.h", for Time.
18246 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18247 Don't assume that the difference between two unsigned long values
18248 can fit into an integer. At this point, we know button_down_time
18249 <= event->timestamp, so the difference must be nonnegative, so
18250 there's no need to cast the result if double-click-time is
18251 nonnegative, as it should be; check that it's nonnegative, just in
18252 case. This bug is triggered when events are more than 2**31 ms
18253 apart (about 25 days). (Bug#8664)
18255 * xselect.c (last_event_timestamp): Remove duplicate decl.
18256 (x_own_selection): Remove needless cast to unsigned long.
18258 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18259 that always fit in int. Use a sentinel instead of a counter, to
18260 avoid a temp and to allay GCC's concerns about possible int overflow.
18261 * frame.h (struct frame): Use int for menu_bar_items_used
18262 instead of EMACS_INT, since it always fits in int.
18264 * menu.c (grow_menu_items): Check for int overflow.
18266 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18268 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18269 Before, the code was not consistent. These values cannot exceed
18270 2**31 - 1 so there's no need to make them unsigned.
18271 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18272 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18273 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18275 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18277 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18278 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18279 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18280 presumably because the widths might not match.
18282 * window.c (size_window): Avoid needless test at loop start.
18284 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18286 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18288 2011-05-12 Drew Adams <drew.adams@oracle.com>
18290 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18292 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18294 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18295 `width' to `bar_area_x' and `bar_area_width', respectively.
18296 (x_scroll_run): Take account of fringe background extension.
18298 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18299 Rename local vars `left' and `width' to `bar_area_x' and
18300 `bar_area_width', respectively.
18301 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18302 background extension.
18304 2011-05-10 Jim Meyering <meyering@redhat.com>
18306 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18308 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18310 * image.c (Finit_image_library): Return t for built-in image types,
18311 like pbm and xbm. (Bug#8640)
18313 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18315 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18317 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18319 * w32console.c (Fset_screen_color): Doc fix.
18320 (Fget_screen_color): New function.
18321 (syms_of_ntterm): Defsubr it.
18323 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18324 unlink the temporary file if Fcall_process didn't create it in the
18326 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18327 child process will be redirected to a file specified with `:file'.
18328 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18329 cue to call_process_cleanup not to close that handle.
18331 2011-05-07 Ben Key <bkey76@gmail.com>
18333 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18334 one of two shell specific rules, either bootstrap-temacs-CMD or
18335 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18336 to the previous implementation of the bootstrap-temacs rule.
18337 The bootstrap-temacs-CMD rule is similar to the previous
18338 implementation of the bootstrap-temacs rule except that it
18339 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18342 These changes, along with some changes to nt/configure.bat,
18343 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18344 earlier fix to add support for --cflags and --ldflags options
18345 that include quotes so that it works whether make uses cmd or
18348 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18350 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18351 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18353 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18354 a string. Handle both cases.
18355 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18356 (Fdbus_register_method): Use Qinvalid_function.
18358 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18360 * makefile.w32-in: Update dependencies.
18361 (LISP_H): Add inttypes.h and stdin.h.
18362 (PROCESS_H): Add unistd.h.
18364 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18366 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18367 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18369 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18371 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18373 * term.c (vfatal): Remove stray call to va_end.
18374 It's not needed and the C Standard doesn't allow it here anyway.
18376 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18377 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18379 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18382 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18384 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18386 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18388 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18390 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18392 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18393 * charset.c (Fdefine_charset_internal): Don't initialize
18394 charset.code_space[15]. The value was garbage, on hosts with
18395 32-bit int (Bug#8600).
18397 * lread.c (read_integer): Be more consistent with string-to-number.
18398 Use string_to_number to do the actual conversion; this avoids
18399 rounding errors and fixes some other screwups. Without this fix,
18400 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18401 (digit_to_number): Move earlier, for benefit of read_integer.
18402 Return -1 if the digit is out of range for the base, -2 if it is
18403 not a digit in any supported base. (Bug#8602)
18405 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18407 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18408 to match comment at start of function. This also removes a
18409 GCC warning about overflow in a 32+64-bit port.
18411 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18413 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18414 Reported by Stefan Monnier in
18415 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18416 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18417 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18419 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18420 (EMACS_UINTPTR): Likewise, with uintptr_t.
18422 * lisp.h: Prefer 64-bit EMACS_INT if available.
18423 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18424 on 32-bit hosts that have 64-bit int, so that they can access
18426 However, temporarily disable this change unless the temporary
18427 symbol WIDE_EMACS_INT is defined.
18429 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18431 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18432 This removes an assumption that EMACS_INT and long are the same
18433 width as pointers. The assumption is true for Emacs porting targets
18434 now, but we want to make other targets possible.
18435 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18436 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18437 In the rest of the code, change types of integers that hold casted
18438 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18439 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18440 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18441 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18442 No need to cast type when ORing.
18443 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18444 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18445 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18446 assume EMACS_INT is the same width as char *.
18447 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18448 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18449 Remove no-longer-needed casts.
18450 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18451 (xg_tool_bar_help_callback, xg_make_tool_item):
18452 Use EMACS_INTPTR to hold an integer
18453 that will be cast to void *; this can avoid a GCC warning
18454 if EMACS_INT is not the same width as void *.
18455 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18456 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18457 (current_message_1, set_message_1):
18458 Use a local to convert to proper width without a cast.
18459 * xmenu.c (dialog_selection_callback): Likewise.
18461 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18462 Also, don't assume VALBITS / RAND_BITS is less than 5,
18463 and don't rely on undefined behavior when shifting a 1 left into
18465 * lisp.h (get_random): Change signature to match.
18467 * lread.c (hash_string): Use size_t, not int, for hash computation.
18468 Normally we prefer signed values; but hashing is special, because
18469 it's better to use unsigned division on hash table sizes so that
18470 the remainder is nonnegative. Also, size_t is the natural width
18471 for hashing into memory. The previous code used 'int', which doesn't
18472 retain enough info to hash well into very large tables.
18473 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18475 * dbusbind.c: Don't possibly lose pointer info when converting.
18476 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18477 Use XPNTR rather than XHASH, so that the high-order bits of
18478 the pointer aren't lost when converting through void *.
18480 * eval.c (Fautoload): Don't double-shift a pointer.
18482 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18484 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18486 * gnutls.c (DEF_GNUTLS_FN):
18487 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18489 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18491 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18494 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18496 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18497 New version that can reserve upto 2GB of heap space.
18499 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18501 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18503 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18505 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18506 `gnutls_certificate_set_x509_key_file'.
18508 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18510 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18511 Update dependencies.
18513 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18515 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18516 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18517 Remove unused parameter `fildes'.
18518 * process.c (read_process_output, send_process): Don't pass it.
18520 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18522 Fix previous change: the library cache is defined in w32.c.
18523 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18524 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18526 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18528 Implement dynamic loading of GnuTLS on Windows.
18530 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18531 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18532 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18535 * gnutls.c (Qgnutls_dll): Define.
18536 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18537 (gnutls_*): Declare function pointers.
18538 (init_gnutls_functions): New function to initialize function pointers.
18539 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18540 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18541 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18542 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18543 (emacs_gnutls_write, emacs_gnutls_read)
18544 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18545 (Fgnutls_available_p): New function.
18546 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18547 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18548 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18550 * image.c: Include w32.h.
18551 (Vimage_type_cache): Delete.
18552 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18553 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18554 (w32_delayed_load): Move to w32.c.
18556 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18558 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18559 (w32_delayed_load): Move from image.c. When loading a library, record
18560 its filename in the :loaded-from property of the library id.
18561 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18562 Initialize and staticpro them.
18563 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18565 * process.c: Include lisp.h before w32.h, not after.
18566 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18567 instead of gnutls_record_check_pending.
18569 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18571 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18573 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18574 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18577 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18579 * xterm.c (x_set_frame_alpha): Do not set property on anything
18580 else than FRAME_X_OUTER_WINDOW (Bug#8608).

18598 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18600 * callproc.c: Indentation fixup.
18602 * sysdep.c (wait_for_termination_1): Make static.
18603 (wait_for_termination, interruptible_wait_for_termination):
18604 Move after wait_for_termination_1.
18606 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18608 * sysdep.c (interruptible_wait_for_termination): New function
18609 which is like wait_for_termination, but allows keyboard
18612 * callproc.c (Fcall_process): Add (:file "file") as an option for
18614 (Fcall_process_region): Ditto.
18616 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18618 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18619 rather than `XVECTOR (FOO)->size'.
18621 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18622 inttypes.h, as a gnulib replacement is used if it not available in
18625 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18627 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18628 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18629 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18631 * coding.c (coding_alloc_by_realloc): Error out if destination
18632 will grow beyond MOST_POSITIVE_FIXNUM.
18633 (decode_coding_emacs_mule): Abort if there isn't enough place in
18634 charbuf for the composition carryover bytes. Reserve an extra

18642 aborting when %lld or %lll format is passed.
18643 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18644 %llo or %llx format is passed. (Bug#8545)
18646 * window.c (window_scroll_line_based): Use a marker instead of
18647 simple variables to record original value of point. (Bug#7952)
18649 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18650 produced by %s or %c overflows available buffer space. (Bug#8545)
18652 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18654 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18655 (SIZE_MAX): Move defn after all includes, as they might #define it.
18657 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18659 * w32.c (init_environment): Warn about defaulting HOME to C:\.

18677 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18679 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18681 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18683 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18685 * makefile.w32-in: Update dependencies.
18687 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18689 Improve `doprnt' and its usage. (Bug#8545)
18690 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18691 `format_end'. Remove support for %l as a conversion specifier.
18692 Don't use xrealloc. Improve diagnostics when the %l size modifier
18693 is used. Update the commentary.
18695 * eval.c (verror): Simplify calculation of size_t.
18697 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18700 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18702 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18705 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18707 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18708 This makes this file independent of the recent pseudovector change.
18710 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18712 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18714 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18715 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18716 Remove unused local.
18717 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18719 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18720 GCC 4.6.0 optimizes based on type-based alias analysis.
18721 For example, if b is of type struct buffer * and v of type struct
18722 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18723 != &v->size, and therefore "v->size = 1; b->size = 2; return
18724 v->size;" must therefore return 1. This assumption is incorrect
18725 for Emacs, since it type-puns struct Lisp_Vector * with many other
18726 types. To fix this problem, this patch adds a new type struct
18727 vectorlike_header that documents the constraints on layout of vectors
18728 and pseudovectors, and helps optimizing compilers not get fooled
18729 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18730 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18731 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18733 (XSETPVECTYPE): Rewrite in terms of new macro.
18734 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18735 This is a bit clearer, and further avoids the possibility of
18736 undesirable aliasing.
18737 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18738 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18739 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18740 since Lisp_Subr is a special case (no "next" field).
18741 (ASIZE): Now uses header.size rather than size.
18742 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18743 to avoid the hassle of writing XVECTOR (foo)->header.size.
18744 (struct vectorlike_header): New type.
18745 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18746 object, to help avoid aliasing.
18747 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18748 (SUBRP): Likewise, since Lisp_Subr is a special case.
18749 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18750 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18751 (struct Lisp_Hash_Table): Combine first two members into a single
18752 struct vectorlike_header member. All uses of "size" and "next" members
18753 changed to be "header.size" and "header.next".
18754 * buffer.h (struct buffer): Likewise.
18755 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18756 * frame.h (struct frame): Likewise.
18757 * process.h (struct Lisp_Process): Likewise.
18758 * termhooks.h (struct terminal): Likewise.
18759 * window.c (struct save_window_data, struct saved_window): Likewise.
18760 * window.h (struct window): Likewise.
18761 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18762 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18763 * buffer.c (init_buffer_once): Likewise.
18764 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18766 * process.c (Fformat_network_address): Use local var for size,
18769 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18771 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18772 * data.c (atof): Remove decl; no longer used or needed.
18773 (digit_to_number): Move to lread.c.
18774 (Fstring_to_number): Use new string_to_number function, to be
18775 consistent with how the Lisp reader treats infinities and NaNs.
18776 Do not assume that floating-point numbers represent EMACS_INT
18777 without losing information; this is not true on most 64-bit hosts.
18778 Avoid double-rounding errors, by insisting on integers when
18779 parsing non-base-10 numbers, as the documentation specifies.
18780 * lisp.h (string_to_number): New decl, replacing ...
18781 (isfloat_string): Remove.
18782 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18783 (read1): Do not accept +. and -. as integers; this
18784 appears to have been a coding error. Similarly, do not accept
18785 strings like +-1e0 as floating point numbers. Do not report
18786 overflow for integer overflows unless the base is not 10 which
18787 means we have no simple and reliable way to continue.
18788 Break out the floating-point parsing into a new
18789 function string_to_number, so that Fstring_to_number parses
18790 floating point numbers consistently with the Lisp reader.
18791 (digit_to_number): Move here from data.c. Make it static inline.
18792 (E_CHAR, EXP_INT): Remove, replacing with ...
18793 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18794 (string_to_number): New function, replacing isfloat_string.
18795 This function checks for valid syntax and produces the resulting
18796 Lisp float number too. Rework it so that string-to-number
18797 no longer mishandles examples like "1.0e+". Use strtoumax,
18798 so that overflow for non-base-10 numbers is reported only when
18799 there's no portable and simple way to convert to floating point.
18801 * textprop.c (set_text_properties_1): Rewrite for clarity,
18802 and to avoid GCC warning about integer overflow.
18804 * intervals.h (struct interval): Use EMACS_INT for members
18805 where EMACS_UINT might cause problems. See
18806 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18807 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18808 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18810 (offset_intervals): Tell GCC not to worry about length overflow
18811 when negating a negative length.
18813 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18814 (overrun_check_free): Likewise.
18816 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18817 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18820 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18821 (gnutls_make_error): Rename local to avoid shadowing.
18822 (gnutls_emacs_global_deinit): ifdef out; not used.
18823 (Fgnutls_boot): Use const for pointer to readonly storage.
18824 Comment out unused local. Fix pointer signedness problems.
18826 * lread.c (openp): Don't stuff size_t into an 'int'.
18827 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18828 about possible signed overflow.
18830 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18831 (GDK_KEY_g): Don't define if already defined.
18832 (xg_prepare_tooltip): Avoid pointer signedness problem.
18833 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18835 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18836 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18838 * xfns.c (Fx_window_property): Simplify a bit,
18839 to make a bit faster and to avoid GCC 4.6.0 warning.
18840 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18842 * fns.c (internal_equal): Don't assume size_t fits in int.
18844 * alloc.c (compact_small_strings): Tighten assertion a little.
18846 Replace pEd with more-general pI, and fix some printf arg casts.
18847 * lisp.h (pI): New macro, generalizing old pEd macro to other
18848 conversion specifiers. For example, use "...%"pI"d..." rather
18849 than "...%"pEd"...".
18850 (pEd): Remove. All uses replaced with similar uses of pI.
18851 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18852 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18853 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18854 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18855 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18856 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18857 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18859 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18860 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18861 * print.c (safe_debug_print, print_object): Likewise.
18862 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18864 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18865 avoiding the 0 flag, which is not portable.
18866 * process.c (Fmake_network_process): Use pI to avoid cast.
18867 * region-cache.c (pp_cache): Likewise.
18868 * xdisp.c (decode_mode_spec): Likewise.
18869 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18870 behavior on 64-bit hosts with printf arg.
18871 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18872 (x_stop_queuing_selection_requests): Likewise.
18873 (x_get_window_property): Don't truncate byte count to an 'int'
18876 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18877 here, since it parses constructs like leading '-' and spaces,
18878 which are not wanted; and it overflows with large numbers.
18879 Instead, simply match F[0-9]+, which is what is wanted anyway.
18881 * alloc.c: Remove unportable assumptions about struct layout.
18882 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18883 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18884 (allocate_vectorlike, make_pure_vector): Use the new macros,
18885 plus offsetof, to remove unportable assumptions about struct layout.
18886 These assumptions hold on all porting targets that I know of, but
18887 they are not guaranteed, they're easy to remove, and removing them
18888 makes further changes easier.
18890 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18891 This doesn't fix a bug but makes the code clearer.
18892 (string_overrun_cookie): Now const. Use initializers that
18893 don't formally overflow signed char, to avoid warnings.
18894 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18895 can cause Emacs to crash when string overrun checking is enabled.
18896 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18897 multiple of sizeof (EMACS_INT); it need not be, if
18898 alignof(EMACS_INT) < sizeof (EMACS_INT).
18899 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18901 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18908 supposed to be handshaking. (Bug#8556)
18909 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18911 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

18928 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18930 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18931 "cast to pointer from integer of different size".
18933 Improve doprnt and its use in verror. (Bug#8545)
18934 * doprnt.c (doprnt): Document the set of format control sequences
18935 supported by the function. Use SAFE_ALLOCA instead of always
18938 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18939 is one byte too soon. Don't use xrealloc; instead xfree and
18942 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18944 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18947 * gnutls.c: Renamed global_initialized to
18948 gnutls_global_initialized. Added internals for the
18949 :verify-hostname-error, :verify-error, and :verify-flags
18950 parameters of `gnutls-boot' and documented those parameters in the
18951 docstring. Start callback support.
18952 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18953 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18954 on error. Return error code.
18955 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18956 (emacs_gnutls_read): Likewise.
18957 (Fgnutls_boot): Return handshake error code.

19021 <char-direction-table>: Deleted.
19023 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19025 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19026 * doprnt.c: Include limits.h.
19027 (SIZE_MAX): New macro.
19028 (doprnt): Return a size_t value. 2nd arg is now size_t.
19029 Many local variables are now size_t instead of int or unsigned.
19030 Improve overflow protection. Support `l' modifier for integer
19031 conversions. Support %l conversion. Don't assume an EMACS_INT
19032 argument for integer conversions and for %c.
19034 * lisp.h (doprnt): Restore prototype.
19036 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19037 $(SRC)/character.h.
19039 * Makefile.in (base_obj): Add back doprnt.o.
19041 * deps.mk (doprnt.o): Add back prerequisites.
19042 (callint.o): Depend on character.h.
19044 * eval.c (internal_lisp_condition_case): Include the handler
19045 representation in the error message.
19046 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19047 when breaking from the loop.
19049 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19051 * callint.c (Fcall_interactively): When displaying error message
19052 about invalid control letter, pass the character's codepoint, not
19053 a pointer to its multibyte form. Improve display of the character
19054 in octal and display also its hex code.
19056 * character.c (char_string): Use %x to display the (unsigned)
19057 codepoint of an invalid character, to avoid displaying a bogus
19060 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19061 `error', not SYMBOL_NAME itself.
19063 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19064 character arguments to `error'.
19066 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19067 to `error' in error message about FINAL_CHAR argument. Make sure
19068 FINAL_CHAR is a character, and use %c when it is passed as
19069 argument to `error'.

19258 * nsfont.m: Fixed bugs in ns_get_family and
19259 ns_descriptor_to_entity that were caused by using free to
19260 deallocate memory blocks that were allocated by xmalloc (via
19261 xstrdup). This caused Emacs to crash when compiled with
19262 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19263 --enable-checking=xmallocoverrun). xfree is now used to
19264 deallocate these memory blocks.

19281 (emacs_read, emacs_write): Use it.
19282 * process.c (send_process): Adjust to the new signatures of
19283 emacs_write and emacs_gnutls_write. Do not attempt to store

19612 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
19613 * lisp.h: Remove these decls.
19615 * buffer.c (buffer_count): Remove unused var.
19617 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
19618 so that it's not optimized away.
19619 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
19620 * dispextern.h (bidi_dump_cached_states): Remove, since it's
19621 exported only to the debugger.
19623 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
19624 * atimer.h (run_all_atimers): Remove; not exported.
19626 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19627 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19628 was inaccessible from Lisp.
19629 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19630 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19632 alloc.c: Import and export fewer symbols, and remove unused items.
19633 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19635 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19636 it's not optimized away by whole-program optimization.
19637 (message_enable_multibyte, free_misc): Remove.
19638 (catchlist, handlerlist, mark_backtrace):
19639 Declare only if BYTE_MARK_STACK.
19640 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
19641 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.

19648 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
19649 (mark_backtrace): Define only if BYTE_MARK_STACK.
19650 * xdisp.c (message_enable_multibyte): Now static.
19652 Declare Lisp_Object Q* variables to be 'static' if not exported.
19653 This makes it easier for human readers (and static analyzers)
19654 to see whether these variables are used from other modules.
19655 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
19656 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
19657 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

19664 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
19665 Remove decls of unexported vars.
19666 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19668 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19670 Make Emacs functions such as Fatom 'static' by default.
19671 This makes it easier for human readers (and static analyzers)
19672 to see whether these functions can be called from other modules.
19673 DEFUN now defines a static function. To make the function external
19674 so that it can be used in other C modules, use the new macro DEFUE.
19675 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19676 (Finit_image_library):
19677 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
19678 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19679 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19680 Remove decls, since these functions are now static.
19681 (Funintern, Fget_internal_run_time): New decls, since these functions
19682 were already external.
19684 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19685 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

19691 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19692 Mark functions with DEFUE instead of DEFUN,
19693 if they are used in other modules.
19694 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19695 decls for now-static functions.
19696 * buffer.h (Fdelete_overlay): Remove decl.
19697 * callproc.c (Fgetenv_internal): Mark as internal.

19706 * image.c (Finit_image_library): New forward static decl.
19707 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
19708 * intervals.h (Fprevious_property_change):
19709 (Fremove_list_of_text_properties): Remove decls.
19710 * keyboard.c (Fthis_command_keys): Remove decl.
19711 (Fcommand_execute): New forward static decl.

19732 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19734 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19735 when at ZV. (Bug#8487)
19737 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19739 * charset.c (Fclear_charset_maps): Use xfree instead of free.

19742 * sound.c (sound_cleanup, alsa_close): Likewise.
19743 * termcap.c (tgetent): Likewise.

19745 * xsettings.c (read_and_apply_settings): Likewise.
19747 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19748 (overrun_check_free): Protoize.
19750 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19752 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19753 since callers should never pass a negative size.
19754 Change the signature to match that of plain 'read' and 'write'; see
19755 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19756 * lisp.h: Update prototypes of emacs_write and emacs_read.
19758 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19760 * xdisp.c (redisplay_window): Don't try to determine the character
19761 position of the scroll margin if the window start point w->startp
19762 is outside the buffer's accessible region. (Bug#8468)
19764 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19766 Fix write-region and its subroutines for buffers > 2GB.
19767 * fileio.c (a_write, e_write): Modify declaration of arguments and
19768 local variables to support buffers larger than 2GB.
19769 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19771 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19772 argument, local variables, and return value.
19774 * lisp.h: Update prototypes of emacs_write and emacs_read.
19776 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19778 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19780 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19782 Fix more problems found by GCC 4.6.0's static checks.
19784 * xdisp.c (vmessage): Use a better test for character truncation.
19786 * charset.c (load_charset_map): <, not <=, for optimization,
19787 and to avoid potential problems with integer overflow.
19788 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19789 * casetab.c (set_identity, shuffle): Likewise.
19790 * editfns.c (Fformat): Likewise.
19791 * syntax.c (skip_chars): Likewise.
19793 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19794 This also lets GCC 4.6.0 generate slightly better loop code.
19796 * callint.c (Fcall_interactively): <, not <=, for optimization.
19797 (Fcall_interactively): Count the number of arguments produced,
19798 not the number of arguments given. This is simpler and lets GCC
19799 4.6.0 generate slightly better code.
19801 * ftfont.c: Distingish more carefully between FcChar8 and char.
19802 The previous code passed unsigned char * to a functions like
19803 strlen and xstrcasecmp that expect char *, which does not
19804 conform to the C standard.
19805 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19806 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19807 char * when the C standard requires it.
19809 * keyboard.c (read_char): Remove unused var.
19811 * eval.c: Port to Windows vsnprintf (Bug#8435).
19812 Include <limits.h>.
19813 (SIZE_MAX): Define if the headers do not.
19814 (verror): Do not give up if vsnprintf returns a negative count.
19815 Instead, grow the buffer. This ports to Windows vsnprintf, which
19816 does not conform to C99. Problem reported by Eli Zaretskii.
19817 Also, simplify the allocation scheme, by avoiding the need for
19818 calling realloc, and removing the ALLOCATED variable.
19820 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19822 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19823 But keep the doprint source code for now, as we might revamp it
19824 and use it again (Bug#8435).
19825 * lisp.h (doprnt): Remove.
19826 * Makefile.in (base_obj): Remove doprnt.o.
19827 * deps.mk (doprnt.o): Remove.
19829 error: Print 32- and 64-bit integers portably (Bug#8435).
19830 Without this change, on typical 64-bit hosts error ("...%d...", N)
19831 was used to print both 32- and 64-bit integers N, which relied on
19832 undefined behavior.
19833 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19834 * lisp.h (error, verror): Mark as printf-like functions.
19835 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19836 Report overflow in size calculations when allocating printf buffer.
19837 Do not truncate output string at its first null byte.
19838 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19839 Truncate the output at a character boundary, since vsnprintf does not
19841 * charset.c (check_iso_charset_parameter): Convert internal
19842 character to string before calling 'error', since %c now has the
19844 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19845 overflow when computing char to be passed to 'error'. Do not
19846 pass Lisp_Object to 'error'; pass the integer instead.
19847 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19848 formatted with plain %d.
19850 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19852 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19854 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19856 * xterm.c (x_catch_errors): Remove duplicate declaration.
19858 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19860 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19862 2011-04-10 Jim Meyering <meyering@redhat.com>
19864 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19865 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19866 return ssize_t not "int", and use size_t as the buffer length.
19867 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19868 * gnutls.h: Update declarations.
19869 * process.c (read_process_output): Use ssize_t, to match.
19870 (send_process): Likewise.
19872 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19874 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19876 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19878 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19879 Use unsigned char, to match FcChar8 type definition.
19881 * xterm.c (handle_one_xevent):
19882 * xmenu.c (create_and_show_popup_menu):
19883 * xselect.c (x_decline_selection_request)
19884 (x_reply_selection_request): Avoid type-punned deref of X events.
19886 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19888 Fix some uses of `int' instead of EMACS_INT.
19889 * search.c (string_match_1, fast_string_match)
19890 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19891 (scan_buffer, find_next_newline_no_quit)
19892 (find_before_next_newline, search_command, Freplace_match)
19893 (Fmatch_data): Make some `int' variables be EMACS_INT.
19895 * xdisp.c (display_count_lines): 3rd argument and return value now
19896 EMACS_INT. All callers changed.
19897 (pint2hrstr): Last argument is now EMACS_INT.
19899 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19900 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19901 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

19904 (decode_coding_ccl, decode_coding_charset)
19905 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
19906 (decode_coding_iso_2022, decode_coding_emacs_mule)
19907 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
19908 <char_offset, last_offset>: Declare EMACS_INT.

19910 (encode_coding_emacs_mule, encode_invocation_designation)
19911 (encode_designation_at_bol, encode_coding_iso_2022)
19912 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19913 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19915 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19916 (encode_invocation_designation): Last argument P_NCHARS is now
19918 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19919 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19921 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19924 * ccl.c (Fccl_execute_on_string): Declare some variables
19927 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19929 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19931 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19933 * process.c (Fformat_network_address): Doc fix.
19935 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19937 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19939 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19941 * keyboard.c (read_char): Call Lisp function help-form-show,
19942 instead of using internal_with_output_to_temp_buffer.
19943 (Qhelp_form_show): New var.
19944 (syms_of_keyboard): Use DEFSYM macro.
19946 * print.c (internal_with_output_to_temp_buffer): Function deleted.
19948 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
19950 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19952 * process.c (Flist_processes): Remove to Lisp.
19953 (list_processes_1): Delete.
19955 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19957 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19959 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19961 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19963 Fix more problems found by GCC 4.6.0's static checks.
19965 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19967 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19969 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19971 * xdisp.c (vmessage): Mark as a printf-like function.
19973 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19975 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19977 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19978 printf-like functions.
19979 (tiff_load): Add casts to remove these marks before passing them
19980 to system-supplied API.
19982 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19984 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19985 This avoids several warnings with gcc -Wstrict-overflow.
19986 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19987 directly, rather than having caller test rule sign. This avoids
19988 some unnecessary tests.
19989 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19990 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19991 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19993 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19994 (xfont_open): Avoid unnecessary tests.
19996 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19998 * composite.h, composite.c (composition_gstring_put_cache):
19999 Use EMACS_INT, not int, for length.
20001 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20002 breaking out part of COMPOSITION_DECODE_RULE.
20003 (COMPOSITION_DECODE_RULE): Use it.
20004 * composite.c (get_composition_id): Remove unused local vars,
20005 by using the new macro.
20007 * textprop.c (set_text_properties_1): Change while to do-while,
20008 since the condition is always true at first.
20010 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20011 (interval_deletion_adjustment): Return unsigned value.
20014 * process.c (list_processes_1, create_pty, read_process_output):

20016 (create_pty): Remove unnecessary "volatile"s.
20017 (Fnetwork_interface_info): Avoid possibility of int overflow.
20018 (read_process_output): Do adaptive read buffering even if carryover.

20030 * print.c (print_error_message): Avoid int overflow.
20032 * font.c (font_list_entities): Redo for clarity,
20033 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

20048 (wordify): Omit three unnecessary tests.
20050 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

20055 * dired.c (file_name_completion): Remove var that is set but not used.
20057 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20059 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20060 (Finsert_file_contents): Remove unnecessary code checking fd.
20062 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20063 Check for integer overflow on size calculations.
20065 * buffer.c (Fprevious_overlay_change): Remove var that is set
20068 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20069 Remove vars that are set but not used.
20070 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20071 (timer_check_2): Mark vars as initialized.
20073 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20075 * image.c (lookup_image): Remove var that is set but not used.
20076 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20078 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20079 that are set but not used.
20081 * xfns.c (make_invisible_cursor): Don't return garbage
20082 if XCreateBitmapFromData fails (Bug#8410).
20084 * xselect.c (x_get_local_selection, x_handle_property_notify):
20085 Remove vars that are set but not used.
20087 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20088 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20090 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20091 Remove var that is set but not used.
20092 (scroll_bar_windows_size): Now size_t, not int.
20093 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20094 Check for overflow.
20096 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20097 (map_tty_color) [!defined MSDOS]: Likewise.
20099 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20101 * coding.c: Remove vars that are set but not used.
20102 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20103 All callers changed.
20104 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20105 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20106 (decode_coding_charset): Remove vars that are set but not used.
20108 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20109 that is set but not used.
20111 * print.c (print_object): Remove var that is set but not used.
20113 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20114 The gnulib version avoids calling malloc in the usual case,
20115 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20116 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20117 * filelock.c (current_lock_owner): Likewise.
20118 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20119 * sysdep.c: Include allocator.h, careadlinkat.h.
20120 (emacs_no_realloc_allocator): New static constant.
20121 (emacs_readlink): New function.
20122 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20123 ../lib/careadlinkat.h.
20125 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20127 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20128 first non-nil return value).

20139 (get_char_face_and_encoding): Remove parameter `multibyte_p',
20140 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20142 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20143 and thereabouts. All callers changed.
20144 (get_per_char_metric): Remove parameter `f', unused since
20145 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20147 2011-04-02 Jim Meyering <meyering@redhat.com>
20149 do not dereference NULL upon failed strdup
20150 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20151 (ns_get_family): Likewise.
20153 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20155 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20157 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20159 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20162 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20164 Add lexical binding.
20166 * window.c (Ftemp_output_buffer_show): New fun.
20167 (Fsave_window_excursion):
20168 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20170 * lread.c (lisp_file_lexically_bound_p): New function.
20171 (Fload): Bind Qlexical_binding.
20172 (readevalloop): Remove `evalfun' arg.
20173 Bind Qinternal_interpreter_environment.
20174 (Feval_buffer): Bind Qlexical_binding.
20175 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20177 (syms_of_lread): Declare `lexical-binding'.
20179 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20181 * keyboard.c (eval_dyn): New fun.
20182 (menu_item_eval_property): Use it.
20184 * image.c (parse_image_spec): Use Ffunctionp.
20186 * fns.c (concat, mapcar1): Accept byte-code-functions.
20188 * eval.c (Fsetq): Handle lexical vars.
20189 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20190 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20191 (FletX, Flet): Obey lexical binding.
20192 (Fcommandp): Handle closures.
20193 (Feval): New `lexical' arg.
20194 (eval_sub): New function extracted from Feval. Use it almost
20195 everywhere where Feval was used. Look up vars in lexical env.
20197 (Ffunctionp): Move from subr.el.
20198 (Ffuncall): Handle closures.
20199 (apply_lambda): Remove `eval_flags'.
20200 (funcall_lambda): Handle closures and new byte-code-functions.
20201 (Fspecial_variable_p): New function.
20202 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20203 but without exporting it to Lisp.
20205 * doc.c (Fdocumentation, store_function_docstring):
20206 * data.c (Finteractive_form): Handle closures.
20208 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20211 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20213 (exec_byte_code): New function extracted from Fbyte_code to handle new
20214 calling convention for byte-code-functions. Add new byte-codes.
20216 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20218 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20220 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20222 * xdisp.c (redisplay_internal): Fix prototype.
20224 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20226 * xdisp.c (SCROLL_LIMIT): New macro.
20227 (try_scrolling): Use it when setting scroll_limit.
20228 Limit scrolling to 100 screen lines.
20229 (redisplay_window): Even when falling back on "recentering",
20230 position point in the window according to scroll-conservatively,
20231 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20233 (try_scrolling): When point is above the window, allow searching
20234 as far as scroll_max, or one screenful, to compute vertical
20235 distance from PT to the scroll margin position. This prevents
20236 try_scrolling from unnecessarily failing when
20237 scroll-conservatively is set to a value slightly larger than the
20238 window height. Clean up the case of PT below the margin at bottom
20239 of window: scroll_max can no longer be INT_MAX. When aggressive
20240 scrolling is in use, don't let point enter the opposite scroll
20241 margin as result of the scroll.
20242 (syms_of_xdisp) <scroll-conservatively>: Document the
20243 threshold of 100 lines for never-recentering scrolling.
20245 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20247 * dispextern.h (move_it_by_lines):
20248 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20249 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20250 (message_log_check_duplicate): Remove parameters `prev_bol' and
20251 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20252 (redisplay_internal): Remove parameter `preserve_echo_area',
20253 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20255 * indent.c (Fvertical_motion):
20256 * window.c (window_scroll_pixel_based, Frecenter):
20257 Don't pass `need_y_p' to `move_it_by_lines'.
20259 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20261 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20262 steal a few bits to be more compact.
20263 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20264 Remove unneeded casts.
20266 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20268 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20270 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20271 binding" message (bug#7967).
20273 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20275 Fix more problems found by GCC 4.6.0's static checks.
20277 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20278 Remove unused local var.
20280 * editfns.c (Fmessage_box): Remove unused local var.
20282 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20283 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20284 Omit unused local vars.
20285 * window.c (shrink_windows): Omit unused local var.
20286 * menu.c (digest_single_submenu): Omit unused local var.
20287 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20288 Omit unused local var.
20290 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20291 Don't assume string length fits in int.
20292 (keyremap_step, read_key_sequence): Use size_t for sizes.
20293 (read_key_sequence): Don't check last_real_key_start redundantly.
20295 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20296 instead of alloca (Bug#8344).
20298 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20299 (Fbacktrace_frame): Don't assume nframes fits in int.
20301 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20303 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20306 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20308 * cm.c (calccost): Turn while-do into do-while, for clarity.
20310 * keyboard.c (syms_of_keyboard): Use the same style as later
20311 in this function when indexing through an array. This also
20312 works around GCC bug 48267.
20314 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20316 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20318 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20319 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20321 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20322 This avoids undefined behavior on integer overflow, and is a bit
20323 more convenient anyway since it is compared to a size_t variable.
20325 Variadic C functions now count arguments with size_t, not int.
20326 This avoids an unnecessary limitation on 64-bit machines, which
20327 caused (substring ...) to crash on large vectors (Bug#8344).

20337 * fns.c (concat): Likewise.
20338 * frame.c (x_set_frame_parameters): Likewise.
20339 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20340 0 if not found, not -1. All callers changed.
20342 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20343 (stack_copy_size): Now size_t, not int.
20344 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20346 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20348 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20349 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20350 All callers changed.
20352 * lisp.h (multibyte_char_to_unibyte):
20353 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20354 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20362 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
20364 * keyboard.c (safe_run_hook_funcall): New function.
20365 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20366 don't set the hook to nil, but remove the offending function instead.
20367 (Qcommand_hook_internal): Remove, unused.
20368 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20369 Vcommand_hook_internal.
20371 * eval.c (enum run_hooks_condition): Remove.
20372 (funcall_nil, funcall_not): New functions.
20373 (run_hook_with_args): Call each function through a `funcall' argument.
20374 Remove `cond' argument, now redundant.

20376 (Frun_hook_with_args_until_failure): Adjust accordingly.
20377 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

20387 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20388 All callers changed.
20390 * w32.c (_wsa_errlist): Use braces for struct initializers.
20392 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
20393 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
20394 All callers changed.

20539 * term.c (Fsuspend_tty, Fresume_tty):
20540 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20541 * window.c (temp_output_buffer_show):

20549 * buffer.c (Fkill_all_local_variables):
20550 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20552 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20553 unconditionally since it does the check itself.
20555 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20557 Fix more problems found by GCC 4.5.2's static checks.
20559 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20560 the first time through the loop, since we know p0 < p1 then.
20561 This also avoids a gcc -Wstrict-overflow warning.
20563 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20564 leading to a memory leak, possible in functions like
20565 load_charset_map_from_file that can allocate an unbounded number
20566 of objects (Bug#8318).
20568 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20569 that could (at least in theory) be that large.
20571 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20572 This is less likely to overflow, and avoids undefined behavior if
20573 overflow does occur. All callers changed. Use strtoul to scan
20574 for the unsigned long integer.
20575 (pint2hrstr): Simplify and tune code slightly.
20576 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20586 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20589 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20591 * process.c (Fmake_network_process): Use socklen_t, not int,
20592 where POSIX says socklen_t is required in portable programs.
20593 This fixes a porting bug on hosts like 64-bit HP-UX, where
20594 socklen_t is wider than int (Bug#8277).
20595 (Fmake_network_process, server_accept_connection):
20596 (wait_reading_process_output, read_process_output):
20599 * process.c: Rename or move locals to avoid shadowing.

20609 Make tparam.h and terminfo.c consistent.
20610 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20611 Include tparam.h instead, since it declares them.
20612 * cm.h (PC): Remove extern decl; tparam.h now does this.
20613 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20614 * terminfo.c: Include tparam.h, to check interfaces.
20615 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20616 (tparam): Adjust signature to match interface in tparam.h;
20617 this removes some undefined behavior. Check that outstring and len
20618 are zero, which they always are with Emacs.
20619 * tparam.h (PC, BC, UP): New extern decls.
20621 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20622 (xftfont_open): Rename locals to avoid shadowing.

20639 (find_automatic_composition, composition_adjust_point): Likewise.
20640 (composition_update_it): Mark var as initialized.
20641 (find_automatic_composition): Mark vars as initialized,
20642 with a FIXME (Bug#8290).

20646 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20647 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20648 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20649 to avoid shadowing.
20651 * textprop.c (property_change_between_p): Remove; unused.
20653 * intervals.c (interval_start_pos): Now static.
20655 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20661 Fix pointer signedness.
20662 (alsa_choose_format): Remove unused local var.
20663 (wav_play): Initialize a variable to 0, to prevent undefined
20664 behavior (Bug#8278).
20666 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20668 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20670 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20671 clobbering (Bug#8298).
20672 * sysdep.c (sys_subshell): Likewise.
20673 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20675 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20676 This should get cleaned up, so that child_setup has the
20677 same signature on all platforms.
20679 * callproc.c (call_process_cleanup): Now static.
20680 (relocate_fd): Rename locals to avoid shadowing.
20682 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20684 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20685 not to be necessary, and produces flickering.
20687 2011-03-20 Glenn Morris <rgm@gnu.org>
20689 * config.in: Remove file.
20691 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20693 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20694 are now in src/globals.h.
20695 (syms_of_minibuf): Remove spurious & from previous change.

20721 (sigchld_handler): Now static.
20723 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20724 That way, the code declares only the vars that it needs.

20734 (CONSTANTLIM): Remove; unused.
20735 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20736 Define only if needed.
20738 * unexelf.c (unexec): Name an expression,
20739 to avoid gcc -Wbad-function-cast warning.
20740 Use a different way to cause a compilation error if anyone uses
20741 n rather than nn, a way that does not involve shadowing.
20742 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20744 * deps.mk (unexalpha.o): Remove; unused.
20746 New file unexec.h, the (simple) interface for unexec (Bug#8267).

20813 (Ftranslate_region_internal, Fformat):
20814 Rename or remove local vars to avoid shadowing.

20817 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20820 * lisp.h (eassert): Check that the argument compiles, even if
20821 ENABLE_CHECKING is not defined.
20823 * data.c (Findirect_variable): Name an expression, to avoid
20824 gcc -Wbad-function-cast warning.

20841 (Fmemory_limit): Cast sbrk's returned value to char *.

20867 (RETALLOC_IF): Define only if needed.
20868 (WORDCHAR_P): Likewise. This one is never needed, but is used
20869 only in a comment talking about a compiler bug, so put inside
20870 the #if 0 of that comment.

20899 New macros, so that the caller can use some names other than
20900 gcpro1, gcpro2, etc.
20901 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20903 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20904 argument, for consistency with GCPRO2_VAR, etc: it is now the

20908 Rename locals to avoid shadowing.
20910 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20911 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20912 dired.c's scmp function, had undefined behavior.
20913 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20914 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20915 * buffer.h: ... to here, because these macros use current_buffer,
20916 and the new implementation with inline functions needs to have
20917 current_buffer in scope now, rather than later when the macros
20919 (downcase, upcase1): New static inline functions.
20920 (DOWNCASE, UPCASE1): Reimplement using these functions.
20921 This avoids undefined behavior in expressions like

20955 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

20962 * buffer.c (fix_overlays_before): Mark locals as initialized.
20963 (fix_start_end_in_overlays): Likewise. This function should be
20964 simplified by using pointers-to-pointers, but that's a different

20968 (report_overlay_modification): Rename locals to avoid shadowing.

20973 to suppress a gcc -Wclobbered warning that does not seem to be right.
20974 (MAXPATHLEN): Define only if needed.

20977 * systty.h: ... to here, so that they can be checked.

20982 * sysdep.c (reset_io): Now static.
20983 (wait_for_termination_signal): Remove; unused.
20985 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

20991 (describe_map_tree):
20992 Rename locals to avoid shadowing.
20994 * keyboard.c: Declare functions static if they are not used elsewhere.

21319 * coding.c (coding_set_source, coding_set_destination):

21323 a block, when the outer 'i' will do.
21324 (decode_coding_utf_8, decode_coding_utf_16, detect_coding_emacs_mule):

21335 (decode_coding_emacs_mule): Mark variables that gcc
21336 -Wuninitialized does not deduce are never used uninitialized.
21337 (detect_coding_iso_2022): Initialize a local variable that might
21338 be used uninitialized. Leave a FIXME because it's not clear that
21339 this initialization is needed. (Bug#8211)
