38 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
40 * xterm.c (syms_of_xterm): Adjust documentation for
41 scroll-bar-adjust-thumb-portion.

102 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
104 * term.c (init_tty): Use them instead of rolling our own code.
105 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
106 switches from 'signal' to 'pthread_sigmask', which is safer in
107 multithreaded applications.
108 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
109 which has already arranged for that.
110 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
111 This is the main part of the bug fix.

121 the type of per-buffer values where appropriate.
122 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
123 predicate, which is how it's really used now. Adjust comment.

125 * buffer.c (buffer_slot_type_mismatch): Remove.
126 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
127 predicate. Adjust comment.

130 left-margin-width, right-margin-width, left-fringe-width,
131 right-fringe-width, scroll-bar-width and buffer-display-count.
132 Use Qstringp for default-directory, buffer-file-name,
133 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
134 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
136 * data.c (store_symval_forwarding): Adjust to call the predicate.
138 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
140 * w32.c (get_name_and_id, acl_set_file):

153 (make_gap_1): New function to adjust the gap of any buffer.
154 * coding.c (coding_alloc_by_making_gap): Use it.
155 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
156 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

179 trailing dash is properly added.
181 2013-01-05 Eli Zaretskii <eliz@gnu.org>
183 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
184 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
185 digits for buffer positions, before misalignment starts.
186 Display "0" for integer "object" field.
187 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
188 Display the newline glyph more unambiguously.
190 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
192 * nsterm.m (ns_draw_underwave):
193 * w32term.c (w32_draw_underwave):
194 * xterm.c (x_draw_underwave): Make underwave look more triangular
195 and also degrade gracefully for small fonts. (Bug#13000)
197 * nsterm.m (ns_draw_text_decoration):
198 * w32term.c (x_draw_glyph_string):
199 * xterm.c (x_draw_glyph_string): Don't use previous underline
200 thickness and position if previous underline type is underwave.

220 * term.c (tty_ins_del_lines):
221 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
222 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
224 2012-12-31 Eli Zaretskii <eliz@gnu.org>
226 * w32.c (unsetenv): Set up the string passed to _putenv
228 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
229 for the bug this caused.
231 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
233 * coding.c (Qmac): Now static.
235 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
237 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
238 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
239 handlebox_widget. Set toolbar_in_hbox to false/true, set
240 toolbar_is_packed to true.
241 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
242 (update_frame_tool_bar): Check toolbar_is_packed for packing.

246 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
247 Check toolbar_is_packed.
248 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
249 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
250 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
252 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
253 (xg_update_menubar): Update title only if
254 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
255 (xg_update_submenu): Skip tearoff only if
256 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.

258 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
260 * xterm.h (struct x_output): Surround handlebox_widget with
261 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,

264 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
266 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
267 (LIBS_GNUSTEP): Define.
268 (LIBES): Add $(LIBS_GNUSTEP).

273 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
274 continuation glyph on a TTY with an indication of an empty line.
277 2012-12-29 Eli Zaretskii <eliz@gnu.org>
279 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
280 file's SELinux context or ACLs successfully set, nil otherwise.
282 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
284 * w32proc.c (reader_thread): Avoid passing NULL handles to
285 SetEvent and WaitForSingleObject.
287 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
289 Port EXTERNALLY_VISIBLE to Clang 3.2.
290 * conf_post.h (__has_attribute): New macro.

300 * fileio.c (file_name_as_directory, directory_file_name):
301 Accept an additional argument MULTIBYTE to indicate whether the input C
302 came from a multibyte or a unibyte Lisp string; all callers
303 adjusted. Don't assume the input string is always multibyte.
305 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
306 don't ENCODE_FILE them, and return a unibyte string if the input
308 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
309 don't assume the input strings will always be multibyte. If the

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

320 * alloc.c (valid_lisp_object_p): Adjust comment.
322 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
324 * keyboard.c (record_asynch_buffer_change): Initialize an event
325 only if it's really needed.
326 * frame.h (enum output_method): Remove output_mac member since
327 it's a leftover from the deleted code.
328 * frame.c (Fframep): Adjust user here ...
329 * terminal.c (Fterminal_live_p): ... and here.
330 * coding.c (Qmac): Now here because it's only used to denote
331 end-of-line encoding type.
332 (syms_of_coding): DEFSYM it.
333 * frame.h (Qmac): Remove duplicated declaration.
335 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
337 * window.c (select_window_1): Now static, since it's used only here.

341 * window.c (window_body_cols): Subtract display margins from the
342 window body width on TTYs as well. See
343 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
344 for the original report.
346 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
348 * xdisp.c (redisplay_window): Remove inner local variable
349 because the outer shadowed one has the same meaning.
350 * xterm.h (struct x_output): Remove toolbar_detached member since it's
352 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
353 (xg_create_tool_bar): Adjust users.
355 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
357 * buffer.h (BUF_COMPACT): New macro to follow the common style.
358 * buffer.c (Fget_buffer_create): Use it to set compact field of
359 struct buffer_text to avoid accessing an uninitialized value
360 when compact_buffer is called for the first time.
361 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
362 (Fset_buffer_modified_p): Use buffer_window_count to check
363 whether the buffer is displayed in some window.
364 * xdisp.c (message_dolog): Likewise.
366 2012-12-23 Eli Zaretskii <eliz@gnu.org>
368 * w32.c (acl_set_file): If setting the file security descriptor
369 fails, and the new DACL is identical to the existing one, silently
370 return success. This fixes problems for users backing up their
371 own files without having the necessary privileges for setting
372 security descriptors.
374 * w32proc.c (reader_thread): Do not index fd_info[] with negative
376 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
377 after WaitForSingleObject returns normally. This expedites reader
378 thread shutdown when delete_child triggers it.
379 (reap_subprocess): More accurate commentary for why we call
380 delete_child only when cp->fd is negative.
382 * w32.c (sys_close): Do not call delete_child on a subprocess
383 whose handle is not yet closed. Instead, set its file descriptor
384 to a negative value, so that reap_subprocess will call
385 delete_child on that subprocess when its SIGCHLD arrives.
386 This avoids closing handles used for communications between sys_select
387 and reader_thread, which doesn't give sys_select a chance to
388 notice that the process exited and invoke the SIGCHLD handler for
391 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
393 * nsfns.m (Fns_do_applescript): Run event loop until script has
394 been executed (Bug#12969).
395 (ns_run_ascript): Chech as_script for nil, set to nil after
398 2012-12-22 Martin Rudalics <rudalics@gmx.at>
400 * window.c (Fselect_window): Reword doc-string (Bug#13248).
402 2012-12-22 Eli Zaretskii <eliz@gnu.org>
404 * w32term.c (w32fullscreen_hook): New function.
405 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
407 2012-12-21 Eli Zaretskii <eliz@gnu.org>
409 * fileio.c (Finsert_file_contents): Doc fix.
411 * w32proc.c (new_child, delete_child, find_child_pid): For a
412 subprocess, consider its slot being in use as long as its process
413 handle (procinfo.hProcess) is not NULL. This avoids reusing the
414 slot when a new process is started immediately after killing
415 another one, without waiting enough time for the first process to
416 be reaped and resources allocated for it be orderly freed.
418 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
420 2012-12-21 Chong Yidong <cyd@gnu.org>
422 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
424 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
426 2012-12-21 Eli Zaretskii <eliz@gnu.org>
428 * w32.c (get_name_and_id): Always pass NULL as the first argument
429 of lookup_account_sid. Avoids crashes with UNC file names that
430 refer to DFS domains, not to specific machine names. (Bug#12621)
431 Remove now unused argument FNAME; all callers changed.
432 (get_file_owner_and_group): Remove now unused argument FNAME; all
435 2012-12-21 Chong Yidong <cyd@gnu.org>
437 * editfns.c (Finsert_char): Since read-char-by-name now signals an
438 error for invalid chars, don't check for a nil return value.
440 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
442 Avoid calls to CHAR_TO_BYTE if byte position is known.
443 * editfns.c (make_buffer_string_both): Use move_gap_both.
444 (Fbuffer_string): Use make_buffer_string_both.
445 * marker.c (buf_charpos_to_bytepos): Convert to eassert.

449 * fileio.c (Finsert_file_contents): Use move_gap_both.
450 * search.c (Freplace_match): Likewise.
451 * process.c (process_send_region): Likewise. Use convenient
452 names for byte positions.
453 * lisp.h (charpos_to_bytepos): Remove prototype.
454 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
455 * insdel.c (move_gap): Likewise.

465 proper value of frame-local variables (bug#13225).
467 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
469 * textprop.c (set_text_properties_1): Do not allow NULL interval.
470 Rename 4th argument since it may be buffer or string. Adjust comment.
471 * intervals.c (graft_intervals_info_buffer): Find an interval here.
473 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
475 * coding.c (Fdetect_coding_region): Do not check start and end with
476 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
477 (code_convert_region): Likewise.
479 2012-12-18 Eli Zaretskii <eliz@gnu.org>
481 * w32.c (acl_get_file, acl_set_file): Run the file name through
482 map_w32_filename, and resolve any symlinks in the file name, like
484 (acl_set_file): Call revert_to_self, if any privileges were
487 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
489 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
490 ($(BLD)/w32.$(O)): Update dependencies.
492 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
494 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
495 propagate redisplay's scrolling (if any) to the right window.
496 (redisplay_internal): Use ensure_selected_frame.
497 (display_mode_lines): Complete last fix.
498 * window.c (select_window_1): New func, extracted from select_window.
499 (select_window): Use it.

528 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
529 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
530 for some of that bug's symptoms can now cause Emacs to abort.
531 Remove the workaround.
532 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
533 The bug that caused SIGCHLD to get lost has been fixed, and the

562 (record_infile, record_pending_deletion): New prototypes.
564 * w32proc.c (new_child): Initialize input_file and
565 pending_deletion members of the child.
566 (delete_child): Delete the child's temporary input file, if any,
567 that is pending deletion.

583 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
584 delete the file, record it as pending deletion when the subprocess
587 2012-12-14 Eli Zaretskii <eliz@gnu.org>

609 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
610 try to get accurate owner and group information from NT file

614 * dired.c (Ffile_attributes) [WINDOWSNT]:
615 Set w32_stat_get_owner_group to a non-zero value, to request accurate
616 owner and group information from 'lstat'.

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

650 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
652 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
653 fstat shouldn't fail, and if it does fail copy-file should not proceed.
654 Remove unnecessary S_ISLNK test, as (contra the comments) this
655 function can't copy symlinks. Improve quality of error message
656 when attempting to copy files that are neither regular files nor

680 * xdisp.c (handle_face_prop): Fix logic of computing
681 it->start_of_box_run_p.
682 (append_space_for_newline): If the glyph row is R2L, reset the
683 iterator's end_of_box_run_p flag before prepending the space glyph.
684 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
685 iterator's start_of_box_run_p flag before prepending the stretch.

993 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
995 Fix a recently-introduced delete-process race condition.
996 * callproc.c, process.h (record_kill_process):
997 New function, containing part of the old call_process_kill.
998 (call_process_kill): Use it.
999 This does not change call_process_kill's behavior.
1000 * process.c (Fdelete_process): Use record_kill_process to fix a
1001 race condition that could cause Emacs to lose track of a child.
1003 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1005 Avoid code duplication between prev_frame and next_frame.
1006 * frame.c (candidate_frame): New function. Add comment.
1007 (prev_frame, next_frame): Use it. Adjust comment.
1009 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1011 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1012 fails, signal an error instead of continuing with an empty
1014 Encode expanded temp file pattern before passing it to mkstemp or
1017 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1018 Encode the file name before passing it to dostounix_filename, in
1019 case it will downcase it (under w32-downcase-file-names).
1022 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1024 Minor call-process cleanups.
1025 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1026 at the same time as other platforms, to simplify analysis.
1027 No need for fd0_volatile since we have synch_process_fd.
1028 Avoid needless emacs_close; arg is always negative.
1030 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1032 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1035 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1037 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1038 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1039 and mouse_face_hidden members to a bitfields.
1040 * frame.h (struct frame): Remove set-but-not-used space_width member.
1041 (FRAME_SPACE_WIDTH): Remove.
1042 * nsterm.m, w32term.c, xterm.c: Adjust users.
1043 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1044 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1045 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1046 members to a bitfields.
1048 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1050 Don't let call-process be a zombie factory (Bug#12980).
1051 Fixing this bug required some cleanup of the signal-handling code.
1052 As a side effect, this change also fixes a longstanding rare race
1053 condition whereby Emacs could mistakenly kill unrelated processes,
1054 and it fixes a bug where a second C-g does not kill a recalcitrant
1055 synchronous process in GNU/Linux and similar platforms.
1056 The patch should also fix the last vestiges of Bug#9488,
1057 a bug which has mostly been fixed on the trunk by other changes.
1058 * callproc.c, process.h (synch_process_alive, synch_process_death)
1059 (synch_process_termsig, sync_process_retcode):
1060 Remove. All uses removed, to simplify analysis and so that
1061 less consing is done inside critical sections.
1062 * callproc.c (call_process_exited): Remove. All uses replaced
1063 with !synch_process_pid.
1064 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1065 These take the role of what used to be in unwind-protect arg.
1067 (block_child_signal, unblock_child_signal):
1068 New functions, to avoid races that could kill innocent-victim processes.
1069 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1070 (call_process_kill): Record killed processes as deleted, so that
1071 zombies do not clutter up the system. Do this inside a critical
1072 section, to avoid a race that would allow the clutter.
1073 (call_process_cleanup): Fix code so that the second C-g works again
1074 on common platforms such as GNU/Linux.
1075 (Fcall_process): Create the child process in a critical section,
1076 to fix a race condition. If creating an asynchronous process,
1077 record it as deleted so that zombies do not clutter up the system.
1078 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1079 light of these changes. Omit unnecessary call to emacs_close
1080 before failure, as the unwind-protect code does that.
1081 * callproc.c (call_process_cleanup):
1082 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1083 * process.c (record_deleted_pid): New function, containing
1084 code refactored out of Fdelete_process.
1085 (Fdelete_process): Use it.
1086 (process_status_retrieved): Remove. All callers changed to use
1087 child_status_change.
1088 (record_child_status_change): Remove, folding its contents into ...
1089 (handle_child_signal): ... this signal handler. Now, this
1090 function is purely a handler for SIGCHLD, and is not called after
1091 a synchronous waitpid returns; the synchronous code is moved to
1092 wait_for_termination. There is no need to worry about reaping
1093 more than one child now.
1094 * sysdep.c (get_child_status, child_status_changed): New functions.
1095 (wait_for_termination): Now takes int * status and bool
1096 interruptible arguments, too. Do not record child status change;
1097 that's now the caller's responsibility. All callers changed.
1098 Reimplement in terms of get_child_status.
1099 (wait_for_termination_1, interruptible_wait_for_termination):
1100 Remove. All callers changed to use wait_for_termination.
1101 * syswait.h: Include <stdbool.h>, for bool.
1102 (record_child_status_change, interruptible_wait_for_termination):
1104 (record_deleted_pid, child_status_changed): New decls.
1105 (wait_for_termination): Adjust to API changes noted above.
1107 * bytecode.c, lisp.h (Qbytecode): Remove.
1108 No longer needed after 2012-11-20 interactive-p changes.
1110 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1112 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1113 the scroll margin, move point outside the margin. (Bug#13055)
1115 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1117 * gtkutil.c (my_log_handler): New function.
1118 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1120 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1122 * lisp.h (modify_region): Rename to...
1123 (modify_region_1): ...new prototype.
1124 * textprop.c (modify_region): Now static. Adjust users.
1125 * insdel.c (modify_region): Rename to...
1126 (modify_region_1): ...new function to work with current buffer.
1127 Adjust comment and users. Use true and false for booleans.
1129 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1131 * alloc.c (free_save_value): New function.
1132 (safe_alloca_unwind): Use it.
1133 * lisp.h (free_save_value): New prototype.
1134 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1136 (save_excursion_restore): Adjust to match saved data structure.
1137 Use free_save_value to offload some work from GC. Drop obsolete
1140 2012-12-03 Chong Yidong <cyd@gnu.org>
1142 * fileio.c (Vauto_save_list_file_name): Doc fix.
1144 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1146 * w32fns.c: Remove prototype of atof.
1147 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1149 (file_dialog_callback): Make it UINT_PTR.
1151 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1154 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1155 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1158 2012-12-03 Glenn Morris <rgm@gnu.org>
1160 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1162 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1164 Fix xpalloc confusion after memory is exhausted.
1165 * alloc.c (xpalloc): Comment fix.
1166 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1167 and signals an error, do not clear charset_table_size, as
1168 charset_table is still valid.
1169 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1171 Use execve to avoid need to munge environ (Bug#13054).
1172 * callproc.c (Fcall_process):
1173 * process.c (create_process):
1174 Don't save and restore environ; no longer needed.
1175 * callproc.c (child_setup):
1176 Use execve, not execvp, to preserve environ.
1178 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1180 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1182 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1184 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1185 display for sliced images (Bug#10500).
1187 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1189 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1191 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1192 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1194 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1196 * xdisp.c (window_outdated): Remove eassert since it hits
1197 some suspicious corner cases (see Bug#13007 and Bug#13012).
1198 (mode_line_update_needed): New function.
1199 (redisplay_internal, redisplay_window): Use it.
1200 (ensure_selected_frame): New function.
1201 (redisplay_internal, unwind_redisplay): Use it.
1202 (redisplay_internal): Move comment about buffer_shared...
1203 (buffer_shared_and_changed): ...near to its real use.
1205 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1207 * callproc.c (Fcall_process): Don't misreport vfork failure.
1209 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1211 * callproc.c (Fcall_process): Fix vfork portability problems.
1212 Do not assume that fd[0], count, filefd, and save_environ survive
1213 vfork. Fix bug whereby wrong errno value could be reported for
1214 pipe failure. Some minor cleanups, too, as follows. Move buf and
1215 bufsize to the context where they're needed. Change new_argv to
1216 be of type char **, as this is more convenient and avoids casts.
1217 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1218 Now local constants, not macros.
1220 2012-11-18 Kenichi Handa <handa@gnu.org>
1222 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1223 for the variable "f".
1225 2012-11-13 Kenichi Handa <handa@gnu.org>
1227 * font.c (font_unparse_xlfd): Exclude special characters from the
1228 generating XLFD name.
1230 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1232 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

1234 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1236 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1243 * lread.c (readbyte_from_file): Assume EINTR is defined.
1244 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1245 Assume EIO and EAGAIN are defined.
1246 * unexcoff.c (write_segment): Assume EFAULT is defined.
1248 2012-11-27 Eli Zaretskii <eliz@gnu.org>

1253 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1254 highlighting on the frame was cleared. Prevents assertion
1255 violations when repeatedly clicking on the "Top" link of the
1256 "bread-crumbs" in Info buffers.

1270 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1271 between bpos_covered and bpos_max. This fixes cursor display when
1272 several display strings follow each other.
1274 * .gdbinit (pgx): If the glyph's object is a string, display the
1275 pointer to string data, rather than the value of the string object
1276 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1278 * indent.c (Fvertical_motion): If the starting position is covered
1279 by a display string, return to one position before that, to avoid
1280 overshooting it inside move_it_to. (Bug#12930)
1282 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

1293 Drop unused pending_menu_activation member.
1294 * xterm.h (struct x_output): Drop outdated #if 0 code.
1295 Use bitfields for explicit_parent, asked_for_visible,
1296 has_been_visible and net_wm_state_hidden_seen members.

1301 of a literal "/". (Bug#12955)
1302 (gl-stamp): Invoke fc.exe directly, not through cmd.

1307 * dired.c: Assume HAVE_DIRENT_H.
1308 (NAMLEN): Remove, replacing with ...
1309 (dirent_namelen): New function. All uses changed. Use the GNU macro
1310 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1311 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1312 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1313 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1315 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1316 * ndir.h: Rename to ../nt/inc/dirent.h.
1317 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1318 Do not include <dirent.h>; no longer needed.
1319 * w32.c: Include <dirent.h> rather than "ndir.h".
1321 2012-11-23 Chong Yidong <cyd@gnu.org>
1323 * xftfont.c (xftfont_open): Remove duplicate assignment.
1325 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1327 * alloc.c (Fgarbage_collect): Unblock input after clearing
1328 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1329 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1330 * msdos.c (IT_frame_up_to_date): Use it here...
1331 * w32term.c (w32_frame_up_to_date): ...here...
1332 * xterm.c (XTframe_up_to_date): ...and here...
1333 * nsterm.m (ns_frame_up_to_date): ...but not here.

1341 * xdisp.c (window_buffer_changed): New function.
1342 (update_menu_bar, update_tool_bar): Use it to
1343 simplify large 'if' statements.

1345 'tail' and 'frame' local variables.
1347 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1349 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1350 with Windows system header.
1352 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1354 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).

1371 * emacs.c (main): Set the G_SLICE environment variable for all
1372 Cygwin builds, not just GTK builds. See
1373 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1375 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1377 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1378 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1379 Define for the MSVC compiler.
1381 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1383 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1384 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1385 dostounix_filename. Prevents crashes down the road, because
1386 dostounix_filename assumes it gets a unibyte string.
1387 Reported by Michel de Ruiter <michel@sentient.nl>, see
1388 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

1414 (text_outside_line_unchanged_p, redisplay_window): Use it.
1415 (redisplay_internal): Likewise. Fix indentation.

1426 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1427 cygwin_convert_file_name*.
1429 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1430 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1432 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>

1436 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1438 * w32select.c: Include w32common.h before w32term.h, so that
1439 windows.h gets included before w32term.h uses some of its
1440 features, see below.
1442 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1444 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

1450 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1451 (ns_select): Return at once if events are held (Bug#12834).
1453 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1455 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1456 Needed following 2012-10-20 change. (Bug#12902)
1458 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1460 * w32proc.c (waitpid): Remove unused label get_result.
1462 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1464 * makefile.w32-in (SYSWAIT_H): New macro.
1465 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1466 ($(BLD)/sysdep.$(O)): Update dependencies.
1468 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1470 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1471 * callproc.c (relocate_fd): Assume F_DUPFD.
1472 * emacs.c, term.c (O_RDWR): Remove.
1473 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1474 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1475 * nsterm.m: Assume <fcntl.h> exists.
1476 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1477 (create_pty, Fmake_network_process, server_accept_connection)
1478 (wait_reading_process_output, init_process_emacs):
1480 (wait_reading_process_output): Put in a special case for WINDOWSNT
1481 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1482 It's not clear this is needed, but it's a more-conservative change.
1483 (create_process): Assume FD_CLOEXEC.
1484 (create_process, create_pty): Assume O_NOCTTY.
1485 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1486 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1487 Omit if not DOS_NT, since F_GETFL is not defined there.
1488 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1489 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1491 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1492 lack it, since gnulib guarantees this.
1493 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1495 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1497 * w32.c (faccessat): Pretend that directories have the execute bit
1498 set. Emacs expects that, e.g., in files.el:cd-absolute.
1500 * w32proc.c (create_child): Don't clip the PID of the child
1501 process to fit into an Emacs integer, as this is no longer a
1503 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1504 reaping only the process specified by PID argument, if that is
1505 positive. Use PID instead of dead_child to know which process to
1506 reap. Wait for the child to die only if WNOHANG is not in
1508 (sys_select): Don't set dead_child.
1510 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1511 as it is no longer needed.
1513 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1515 (record_child_status_change): Remove the setting of
1516 record_at_most_one_child for the !WNOHANG case.
1518 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1520 Fix problems in ns port found by static checking.
1521 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1522 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1523 not to process group.
1524 (ns_select): Use emacs_write, not write, as that's more robust
1525 in the presence of signals.
1526 (fd_handler:): Check for read errors.
1528 2012-11-16 Glenn Morris <rgm@gnu.org>
1530 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1532 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1534 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1536 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1538 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1539 use the same value of thread handle.
1540 (start_timer_thread): If the timer thread exited (due to error),
1541 clean up by closing the two handles it used. Duplicate the caller
1542 thread's handle here, so it gets duplicated only once, when
1543 launching the timer thread. Set priority of the timer thread, not
1545 (getitimer): Don't duplicate the caller thread's handle here.
1548 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1550 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1553 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1555 Remove no-longer-used pty_max_bytes variable.
1556 * process.c (pty_max_bytes): Remove; unused.
1557 (send_process): Do not set it.
1559 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1561 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1562 Update dependencies.
1564 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1566 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1567 This follows up on the 2012-09-29 patch that removed indirection
1568 for the 'function' field. Reported by Sergey Vinokurov in
1569 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1571 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1573 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1574 different name, as the MS runtime does not have such a function,
1575 and probably never will.) All callers changed. Ignore DIRFD
1576 value if PATH is an absolute file name, to match Posix spec
1577 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1580 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1582 * xdisp.c (echo_area_display, redisplay_internal):
1583 Omit redundant check whether frame_garbaged is set.
1585 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1587 Use faccessat, not access, when checking file permissions (Bug#12632).
1588 This fixes a bug that has been present in Emacs since its creation.
1589 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1590 which must set some sort of record. (Torek's bug report was against
1591 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1592 same common flaw.) See Torek's Usenet posting
1593 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1594 Posted: Fri Apr 8 14:18:56 1983.
1595 * Makefile.in (LIB_EACCESS): New macro.
1597 * callproc.c (init_callproc):
1598 * charset.c (init_charset):
1599 * fileio.c (check_existing, check_executable, check_writable)
1601 * lread.c (openp, load_path_check):
1602 * process.c (allocate_pty):
1604 Use effective UID when checking permissions, not real UID.
1605 * callproc.c (init_callproc):
1606 * charset.c (init_charset):
1607 * lread.c (load_path_check, init_lread):
1608 Test whether directories are accessible, not merely whether they exist.
1609 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1610 * fileio.c (check_existing, check_executable, check_writable)
1612 Use symbolic names instead of integers for the flags, as they're
1614 (check_writable): New arg AMODE. All uses changed.
1615 Set errno on failure.
1616 (Ffile_readable_p): Use faccessat, not stat + open + close.
1617 (Ffile_writable_p): No need to call check_existing + check_writable.
1618 Just call check_writable and then look at errno. This saves a syscall.
1619 dir should never be nil; replace an unnecessary runtime check
1620 with an eassert. When checking the parent directory of a nonexistent
1621 file, check that the directory is searchable as well as writable, as
1622 we can't create files in unsearchable directories.
1623 (file_directory_p): New function, which uses 'stat' on most platforms
1624 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1625 (Ffile_directory_p, Fset_file_times): Use it.
1626 (file_accessible_directory_p): New function, which uses a single
1627 syscall for efficiency.
1628 (Ffile_accessible_directory_p): Use it.
1629 * xrdb.c (file_p): Use file_directory_p.
1630 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1631 * lread.c (openp): When opening a file, use fstat rather than
1632 stat, as that avoids a permissions race. When not opening a file,
1633 use file_directory_p rather than stat.
1634 (dir_warning): First arg is now a usage string, not a format.
1635 Use errno. All uses changed.
1636 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1637 that merely introduced a race.
1638 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1639 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1640 and similarly for the other O_* flags.
1641 * w32.c (sys_faccessat): Rename from sys_access and switch to
1642 faccessat's API. All uses changed.
1643 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1644 (magic_db): Rename from magic_file_p.
1645 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1646 char *, so that we don't have to test for file existence
1647 separately from opening the file for reading. This removes a race
1648 fixes a permission-checking problem, and simplifies the code.
1650 (file_p): Remove; no longer needed.
1652 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1654 Omit glyphs initialization at startup.
1655 * dispnew.c (glyphs_initialized_initially_p): Remove.
1656 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1657 (Fredraw_frame): Move actual code from here...
1658 (redraw_frame): ...to here. Add eassert. Adjust comment.
1659 (Fredraw_display): Use redraw_frame.
1660 * xdisp.c (clear_garbaged_frames): Likewise.
1662 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1664 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1665 passed to pint2str and pint2hrstr to be at most the size of the
1666 frame's decode_mode_spec_buffer. This avoids crashes with very
1667 large values of FIELD_WIDTH argument to decode_mode_spec.
1670 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1672 Fix a race with verify-visited-file-modtime (Bug#12863).
1673 Since at least 1991 Emacs has ignored an mtime difference of no
1674 more than one second, but my guess is that this was to work around
1675 file system bugs that were fixed long ago. Since the race is
1676 causing problems now, let's remove that code.
1677 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1678 whose time stamp is off by no more than a second. Insist that the
1679 file time stamps match exactly.
1681 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1683 * frame.h (struct frame): Convert external_tool_bar member to
1684 1-bit unsigned bitfield.
1685 * termhooks.h (struct terminal): Remove mouse_moved member since
1686 all users are long dead. Adjust comment on mouse_position_hook.
1688 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1690 Simplify by using FOR_EACH_FRAME here and there.
1691 * frame.c (next_frame, prev_frame, other_visible_frames)
1692 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1693 * w32term.c (x_window_to_scroll_bar): Likewise.
1694 * window.c (window_list): Likewise.
1695 * xdisp.c (x_consider_frame_title): Likewise.
1696 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1697 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1698 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1699 * xmenu.c (menubar_id_to_frame): Likewise.
1700 * xselect.c (frame_for_x_selection): Likewise.
1701 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1702 (x_window_to_menu_bar): Likewise.
1703 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1705 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1707 * data.c (Qdefalias_fset_function): Now static.
1709 Another tweak to vectorlike_header change.
1710 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1711 Remove, and replace all uses with ...
1712 (next_in_free_list, set_next_in_free_list):
1713 New functions, which respect C's aliasing rules better.
1715 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1717 * window.c (list4i): Rename from 'quad'. All uses changed.
1718 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1720 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1722 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1723 warning about mixing declarations and code in ISO C90.
1725 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1727 * window.c (Fsplit_window_internal): Set combination limit of
1728 new parent window to t iff Vwindow_combination_limit is t;
1729 fixing a regression introduced with the change from 2012-09-22.
1730 (Fset_window_combination_limit): Fix doc-string.
1732 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1734 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1735 amount when the scroll margins are too large. When scrolling
1736 backwards in the buffer, give up if cannot reach point or the
1737 scroll margin within a reasonable number of screen lines.
1738 Fixes point position in window under scroll-up/down-aggressively when
1739 point is positioned many lines beyond the window top/bottom.
1742 * ralloc.c (relinquish): If real_morecore fails to return memory
1743 to the system, don't crash; instead, leave the last heap
1744 unchanged and return. (Bug#12774)
1746 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1748 * lisp.h (AUTOLOADP): New macro.
1749 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1750 * data.c (Ffset): Remove special ad-advice-info handling.
1751 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1753 (Finteractive_form): Simplify.
1754 (Fquo): Don't insist on having at least 2 arguments.
1755 (Qdefalias_fset_function): New var.
1757 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1759 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

1765 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1767 Fix recently introduced crash on MS-Windows (Bug#12839).
1768 * w32term.h (struct scroll_bar): Use convenient header.
1769 (SCROLL_BAR_VEC_SIZE): Remove.
1770 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1772 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1774 Tweak last vectorlike_header change.
1775 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1776 vectorlike object on the free list. This is introduced to avoid
1777 some (but not all) pointer casting and aliasing problems, see
1778 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1779 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1781 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1783 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1785 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1786 been removed, so remove them here also.
1788 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1790 * doc.c (Fdocumentation): Handle new property
1791 dynamic-docstring-function to replace the old ad-advice-info.
1793 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1795 * fns.c (Qeql, hashtest_eq): Now static.

1801 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
1802 * buffer.c (compare_overlays): Use XLI rather than XHASH.
1804 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1806 Use same hash function for hashfn_profiler as for hash_string etc.
1807 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1808 * lisp.h (sxhash_combine): New inline function, with the contents
1809 of the old SXHASH_COMBINE.
1810 * profiler.c (hashfn_profiler): Use it, instead of having a
1811 special hash function containing a comparison that always yields 1.
1813 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1815 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1816 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1817 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1820 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1822 * image.c (xpm_make_color_table_h): Fix compiler error because
1823 make_hash_table changed.
1825 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1827 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1829 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1831 Use ad-hoc comparison function for the profiler's hash-tables.
1832 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1833 (make_log): Use them.
1834 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1835 call Fequal any more.

1844 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1845 (hash_lookup, hash_remove_from_table): Move assertion checking of
1846 hashfn result here. Check hash-equality before calling cmpfn.

1856 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1858 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1859 value of w32-scroll-lock-modifier is neither nil nor one of the
1860 known key modifiers. (Bug#12806)
1862 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1864 Shrink struct vectorlike_header to the only size field.
1865 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1867 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1868 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1869 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1870 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1871 information from the vector header. Adjust comment.

1882 (NEXT_IN_FREE_LIST): New macro.
1883 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1884 (Fmake_bool_vector): Likewise.
1885 (struct large_vector): New type to represent allocation unit for
1886 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1887 (large_vectors): Change type to struct large_vector.
1888 (allocate_vector_from_block): Simplify.
1889 (PSEUDOVECTOR_NBYTES): Replace with...
1890 (vector_nbytes): ...new function. Adjust users.

1896 (live_vector_p): Adjust to match large vector.
1897 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1898 * buffer.h (struct buffer): Add next member.
1899 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1901 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1902 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1903 (copy_hash_table): Adjust to match vector header change.
1904 * lread.c (defsubr): Use XSETPVECTYPE.
1905 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
1906 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
1907 (xvecsize): New command.
1909 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1911 * keyboard.c (event_to_kboard): Do not dereference
1912 frame_or_window field of SELECTION_REQUEST_EVENT
1913 and SELECTION_CLEAR_EVENT events (Bug#12814).
1914 * xterm.h (struct selection_input_event): Adjust comment.
1916 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1918 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1919 such as Scroll Lock, if the respective keys are treated as
1920 function keys, not as modifiers. This avoids destroying non-ASCII
1921 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1923 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1925 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1927 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1929 Restore some duplicate definitions (Bug#12814).
1930 This undoes part of the 2012-11-03 changes. Some people build
1931 with plain -g rather than with -g3, and they need the duplicate
1932 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1933 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1934 Define as macros, as well as as enums or as constants.
1936 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1938 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1939 to keypad keys (Bug#12816).
1941 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1943 Minor adjustments of recently-changed frame functions.
1944 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1945 known to be a frame (we're in the FRAMEP branch).
1946 * lisp.h (Qframep): Remove decl. frame.h declares this.
1947 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1948 since they're meant for Lisp fixnum values.
1950 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1952 * window.c (Fwindow_combination_limit): Revert to the only
1953 required argument and adjust docstring as suggested in
1954 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1955 by Martin Rudalics <rudalics@gmx.at>.
1957 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1959 Widely used frame validity and checking functions.
1960 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1961 * frame.c (decode_live_frame, decode_any_frame): New functions.
1962 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1963 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1964 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1965 (Fframe_pointer_visible_p): Use decode_any_frame.
1966 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
1967 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
1968 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1969 (Fframe_focus): Likewise. Allow zero number of arguments.
1971 (frame_buffer_list, frame_buffer_predicate): Remove.
1972 * lisp.h (frame_buffer_predicate): Remove prototype.
1973 * buffer.c (Fother_buffer): Use decode_any_frame.
1974 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1975 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1976 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1977 (Fclose_font, Ffont_info): Use decode_live_frame.
1978 * fontset.c (check_fontset_name): Likewise.
1979 * terminal.c (Fframe_terminal): Likewise.
1980 * w32fns.c (check_x_frame): Likewise.
1981 * window.c (Fminibuffer_window, Fwindow_at)
1982 (Fcurrent_window_configuration): Likewise.
1983 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1984 Likewise. Allow zero number of arguments. Adjust docstring.
1985 * dispnew.c (Fredraw_frame): Likewise.
1986 * xfaces.c (frame_or_selected_frame): Remove.
1987 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1988 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1989 (Fframe_face_alist): Use decode_live_frame.
1990 * xfns.c (check_x_frame): Likewise.
1992 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1994 * window.c (quad): New function.
1995 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1996 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1997 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1998 (Fwindow_line_height): Use it.
1999 (Fwindow_fringes): Use list3.
2000 (Fwindow_scroll_bars): Use list4.
2001 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2002 (Fwindow_combination_limit): Allow zero number of arguments.
2004 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2006 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2008 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2009 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2010 file descriptor 2 for standard error. (Bug#12805)
2012 2012-11-05 Chong Yidong <cyd@gnu.org>
2014 * process.c (wait_reading_process_output): Revert previous change.
2016 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2018 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2019 This removes code that has been obsolete since around 1990.
2020 * callproc.c (Fcall_process):
2022 * process.c (create_process):
2023 * term.c (dissociate_if_controlling_tty):
2024 Assume setsid exists.
2025 * callproc.c (child_setup): Assume setpgid exists and behaves as
2026 per POSIX.1-1988 or later.
2027 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2028 * emacs.c (shut_down_emacs):
2029 * sysdep.c (sys_suspend, init_foreground_group):
2030 Assume getpgrp behaves as per POSIX.1-1998 or later.
2031 * msdos.c (setpgrp): Remove.
2032 (tcgetpgrp, setpgid, setsid): New functions.
2033 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2034 * term.c (no_controlling_tty): Remove; unused.
2035 * w32proc.c (setpgrp): Remove.
2036 (setsid, tcgetpgrp): New functions.
2038 Simplify by assuming __fpending.
2039 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2040 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2041 Do not assume that __fpending's result fits in int.
2043 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2045 Remove EMACS_OUTQSIZE+sleep hack.
2046 * dispnew.c (update_frame_1): Remove hack for terminals slower
2047 than 2400 bps, which throttled Emacs by having it sleep.
2048 This code hasn't worked since at least 2007, when the multi-tty stuff
2049 was added, and anyway those old terminals are long dead.
2050 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2051 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2053 Fix data-loss with --version (Bug#9574).
2054 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2055 as we can't assume that emacs_strerror is initialized, and strerror
2056 is good enough here.
2057 (main): Invoke atexit earlier, to catch earlier instances of
2058 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2060 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2062 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2063 (keyDown): Remap keypad keys to X11 virtual key codes.
2065 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2067 Fix data-loss with --batch (Bug#9574).
2068 * emacs.c: Include <close-stream.h>.
2069 (close_output_streams): New function.
2070 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2071 and handles errors appropriately.
2072 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2075 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2076 The symptom is a diagnostic "GLib-WARNING **: In call to
2077 g_spawn_sync(), exit status of a child process was requested but
2078 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2079 waitpid(), so exit status can't be returned." The diagnostic
2080 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2081 The real bug is a race condition between Emacs and glib: Emacs
2082 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2083 so that glib can't find it. Work around the bug by invoking
2084 waitpid only on subprocesses that Emacs itself creates.
2085 * process.c (create_process, record_child_status_change):
2086 Don't use special value -1 in pid field, as the caller now must
2087 know the pid rather than having the callee infer it.
2088 The inference was sometimes incorrect anyway, due to another race.
2089 (create_process): Set new 'alive' member if child is created.
2090 (process_status_retrieved): New function.
2091 (record_child_status_change): Use it.
2092 Accept negative 1st argument, which means to wait for the
2093 processes that Emacs already knows about. Move special-case code
2094 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2095 processes that have already been waited for, by testing and
2096 clearing new 'alive' member.
2097 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2098 now does this internally.
2099 (handle_child_signal): Let record_child_status_change do all
2100 the work, since we do not want to reap all exited child processes,
2101 only the child processes that Emacs itself created.
2102 * process.h (Lisp_Process): New boolean member 'alive'.
2104 Omit duplicate definitions no longer needed with gcc -g3.
2105 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2106 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2107 Define only as macros. There's no longer any need to also define
2108 these symbols as enums or as constants, since we now assume
2109 gcc -g3 when debugging.
2111 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2113 * lisp.mk: Adjust comments to the fact that term/internal is now
2114 loaded from loadup.el.
2116 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2117 (msdos_fatal_signal): New function.
2118 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2121 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2122 for GCC versions before 4.
2123 (emacs_raise): Define to call msdos_fatal_signal.
2125 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2126 iterator when starting in the middle of a display or overlay
2129 2012-11-03 Chong Yidong <cyd@gnu.org>
2131 * process.c (wait_reading_process_output): Clean up the last
2134 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2136 * process.c (wait_reading_process_output): Avoid a race condition
2137 with SIGIO delivery (Bug#11536).
2139 2012-11-03 Chong Yidong <cyd@gnu.org>
2141 * buffer.c (cursor_type): Untabify docstring.
2143 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2145 * frame.h (struct frame): Drop can_have_scroll_bars member
2146 which is meaningless for a long time. Adjust comments.
2147 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2148 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2150 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2152 * window.c (decode_next_window_args): Update window arg after
2153 calling decode_live_window and so fix crash reported at
2154 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2155 by Juanma Barranquero <lekktu@gmail.com>.
2156 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2157 * font.c (Ffont_at): Likewise.
2159 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2161 * widget.c (resize_cb): New function.
2162 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2163 (EmacsFrameResize): Check if all is up to date before changing frame
2166 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2168 Implement backtrace output for fatal errors on MS-Windows.
2169 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2170 (BACKTRACE_LIMIT_MAX): New macro.
2171 (w32_backtrace): New function.
2172 (emacs_abort): Use w32_backtrace when the user chooses not to
2173 attach a debugger. Update the text of the abort dialog.
2175 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2177 Window-related stuff cleanup here and there.
2178 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2179 Use decode_any_window.
2180 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2181 * xdisp.c (Fformat_mode_line): Likewise.
2182 * font.c (Ffont_at): Use decode_live_window.
2183 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2184 * window.c (decode_next_window_args): Likewise.
2185 (decode_any_window): Remove static.
2186 * window.h (decode_any_window): Add prototype.
2187 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2188 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2191 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2193 Remove pad from struct input_event.
2194 * termhooks.h (struct input_event): Remove padding field.
2196 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2197 member is never cons for a long time. Adjust comment.
2198 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2199 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2200 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2201 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2203 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2205 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2207 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2209 Fix crash when using Emacs as commit editor for git (Bug#12697).
2210 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2211 and it is configured in conf_post.h.
2212 (Fcall_process): Don't invoke both setsid and setpgid; the former
2213 is enough, if it exists.
2214 * callproc.c (Fcall_process, child_setup):
2215 * process.c (create_process): Use setpgid.
2216 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2218 * dispnew.c (init_display): Initialize the foreground group
2219 if we are running a tty display.
2220 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2221 * lisp.h (init_foreground_group): New decl.
2222 * sysdep.c (inherited_pgroup): New static var.
2223 (init_foreground_group, tcsetpgrp_without_stopping)
2224 (narrow_foreground_group, widen_foreground_group): New functions.
2225 (init_sys_modes): Narrow foreground group.
2226 (reset_sys_modes): Widen foreground group.
2228 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2230 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2232 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2234 * minibuf.c (read_minibuf): Restore current buffer since
2235 choose_minibuf_frame calling Fset_frame_selected_window may
2236 change it (Bug#12766).
2238 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2240 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2242 2012-10-30 Kenichi Handa <handa@gnu.org>
2244 * font.c (Ffont_at): If WINDOW is specified and it is not
2245 displaying the current buffer, signal an error.
2247 2012-10-29 Daniel Colascione <dancol@dancol.org>
2249 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2250 In preparation for fixing bug#12739, move these functions from
2253 * coding.h, coding.c: ... to here, and compile them only when
2254 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2255 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2257 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2259 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2260 (timer_loop, getitimer, setitimer): Use it instead of
2261 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2263 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2266 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2268 * nsterm.m (NO_APPDEFINED_DATA): New define.
2269 (last_appdefined_event_data): New variable
2270 (last_appdefined_event): Remove.
2271 (ns_select): Initialize t from last_appdefined_event_data instead
2272 of [last_appdefined_event data1].
2273 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2274 remove last_appdefined_event (Bug#12698).
2276 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2278 * frame.c (x_set_font): Catch internal error.
2280 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2282 Avoid overflow in w32 implementation of interval timers.
2283 When possible, for ITIMER_PROF count only times the main thread
2285 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2286 'volatile ULONGLONG' types. All the other data which was
2287 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2288 (GetThreadTimes_Proc): New typedef.
2289 (w32_get_timer_time): New function, returns a suitable time value
2291 (timer_loop): Enter critical section when accessing ULONGLONG
2292 values of the itimer_data struct, as these accesses are no longer
2293 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2294 Remove unused variable.
2295 (init_timers): Initialize s_pfn_Get_Thread_Times.
2296 (start_timer_thread): Don't assign itimer->caller_thread here.
2297 (getitimer): Assign itimer->caller_thread here.
2298 (setitimer): Always call getitimer to get the value of ticks_now.
2299 (sys_spawnve): Avoid compiler warning about format mismatch.
2301 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2303 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2304 mouse movement events if the menu bar is active. This avoids
2305 producing a busy "hour-glass" cursor by Windows if the mouse
2306 pointer is positioned over a tooltip shown for some menu item.
2308 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2310 Don't assume process IDs fit in int.
2311 * emacs.c (shut_down_emacs) [!DOS_NT]:
2312 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2313 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2314 Use pid_t, not int, to store process IDs, as 'int'
2315 is not wide enough on a few platforms (e.g., AIX and IRIX).
2317 2012-10-23 Kenichi Handa <handa@gnu.org>
2319 The following change is to make face-font-rescale-alist work
2320 correctly for non-ASCII fonts.
2322 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2323 (font_open_for_lface): Handle Vface_font_rescale_alist.
2325 2012-10-23 Chong Yidong <cyd@gnu.org>
2327 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2329 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2331 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2333 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2335 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2338 2012-10-21 Glenn Morris <rgm@gnu.org>
2340 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.

2822 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2823 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2824 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2825 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2826 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2827 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2828 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2829 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2830 now a supported configuration.
2832 * Makefile.in: consolidate image variables into LIBIMAGE; add
2833 W32_OBJ and W32_LIBS. Compile new files.
2836 (_DebPrint) declare tracing facility for W32 debugging. We need
2837 to unify tracing later.
2839 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2840 unconditional use of W32 Unicode functions. Cygwin runs only on
2841 100% Unicode operating systems.
2843 * cygw32.c: New file. Define Cygwin-specific facilities.
2844 (Fcygwin_convert_path_to_windows)
2845 (Fcygwin_convert_path_from_windows): New user functions for
2846 accessing Cygwin path-munging routines.
2848 * cygw32.h: New file.
2849 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2850 UTF-16LE strings temporarily inside non-Lisp-visible string
2853 (w32_strerror): Just what it says on the tin.
2855 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2856 also run for Cygwin; both systems have the same problem with using
2857 GUI facilities in a forked child. Also call syms_of_cygw32,
2858 syms_of_w32select in correct places.
2860 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2861 needs fork-then-exec for daemon launching.
2863 * font.h: Include frame.h.
2865 * image.c: Use the image library cache machinery only when we're
2866 compiling for native WINDOWSNT; Cygwin can use shared libraries
2867 like any other Unixlike system.
2869 * keyboard.c: Clarify a comment regarding the input loop.
2871 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2872 functions directly instead of trying to detect at runtime that our
2873 host operating system supports them. We make this change for two
2874 reasons: Cygwin lacks support for the multibyte character
2875 conversion functions used by the legacy menu code, and Cygwin
2876 never needs to rely on non-Unicode APIs.
2878 * unexw32.c (hinst): Declare extern.
2880 * w32.c: Change header order;
2881 (w32_strerror): Move to w32fns.c because we need it for
2882 non-WINDOWSNT builds.
2884 * w32.h: Add #error macro to make sure we don't include w32.h for
2885 Cygwin builds. Remove w32select declarations.
2887 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2888 w32fns.c. w32console.c is WINDOWSNT-only.
2890 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2891 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2893 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2894 (w32_major_version, w32_minor_version, w32_build_number)
2895 (os_subtype, sound_type): Define here
2896 (w32_defined_color): Make color parameter const for consistency
2897 with other _defined_color functions.
2898 (w32_createwindow): Unconditionally call w32_init_class instead of
2899 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2900 through the code is complex and unnecessary because class
2901 registration is practically free.
2902 (w32_name_of_message): New EMACSDEBUG-only function.
2903 (Fset_message_beep): Move here
2904 (Fx_open_connection): Require that the display name for Windows be
2905 "w32" for consistency, emacsclient disambiguation, and maybe, one
2906 day, multi-window-system support.
2907 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2908 Cygwin files for W32 GUI facilities, since these clearly don't
2909 expect Cygwin names.
2910 (_DebPrint): Define.
2911 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2912 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2913 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2914 (w32_last_error): Remove.
2916 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2918 * w32heap.c (syspage_mask): Declare here.
2919 (cache_system_info): Remove.
2921 * w32inevt.c (faked_key): Define globally, not statically.
2922 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2923 (w32_console_toggle_lock_key): Move to w32fns.c.
2925 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2927 * w32proc.c (_DebPrint): Move to w32fns.c.
2928 * w32select.c: Include string.h, stdio.h for Cygwin.
2929 * w32select.h: New File.
2931 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2933 (w32_message_fd): New variable. Under Cygwin, holds the file
2934 descriptor the system used to tell us about pending thread
2937 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2938 that prevented compilation under non-WINDOWSNT systems.
2940 (w32_initialize): Open /dev/windows and assign it to
2941 w32_message_fd. Provide w32 feature.
2943 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2944 (WM_EMACS_INPUT_READY): add.
2945 (prepend_msg, w32_message_fd): Declare globally.
2948 (keyboard_handle): Use only when WINDOWSNT.
2949 (notify_msg_ready): New function. Posts a message to the main
2950 thread's message queue under CYGWIN, which wakes up the main
2951 thread from select(2) by making the /dev/windows file descriptor
2952 ready. Under WINDOWSNT, it sets an event the same way the old
2955 (post, prepend_msg): Actually call notify_msg_ready instead of
2956 setting the input event directly.
2958 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2960 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2961 but it still has blocs in it, don't return it to the system,
2962 instead of aborting. (Bug#12402)
2964 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2966 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2968 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2969 MAC_OS_X_VERSION_10_6.
2970 (syms_of_nsterm): Remove comment about Panther and above for
2972 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2973 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2974 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2976 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2977 MAC_OS_X_VERSION_10_4.
2979 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2980 MAC_OS_X_VERSION_10_2.
2982 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2984 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2985 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2987 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2988 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2989 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2990 Remove ns_in_resize check.
2991 (ns_clear_frame_area): Remove resize handle code.
2993 * nsfns.m (ns_in_resize): Remove.
2994 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2995 Remove ns_in_resize check.
2997 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2999 Improve sys_siglist detection.
3000 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3001 defined as a macro, as is done in Solaris.
3002 (sys_siglist_entries): New macro.
3003 (save_strsignal): Use it.
3004 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3005 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3007 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3009 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3010 fullscreen/Fullscreen.
3012 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3013 tobar_height is new.
3015 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3016 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3017 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3018 (windowDidResize:): Check for correct window if old style fullscreen.
3019 Capitalize word in comment. Remove incorrect comment.
3020 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3021 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3022 error in drawing background.
3023 (toggleFullScreen:): Remove comment. Rearrange calls.
3024 Set toolbar values to zero, save old height in tobar_height.
3025 Restore tool bar height when leaving fullscreen.
3026 (canBecomeMainWindow): New function.
3028 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3030 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3032 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3034 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3036 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3037 that time stamps of directories could also be changed.
3038 Don't request the too broad GENERIC_WRITE, only the more restrictive
3039 FILE_WRITE_ATTRIBUTES access rights.
3041 * fileio.c (Fset_file_times): Special-case ignoring errors for
3042 directories only on MSDOS, not on MS-Windows.
3044 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3046 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3048 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3050 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3051 see whether CreateFile failed.
3053 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3055 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3056 to avoid similar races.
3057 * keyboard.c (pending_signals): Now bool, not int.
3059 Port timers to OpenBSD, plus check for timer failures.
3060 OpenBSD problem reported by Han Boetes.
3061 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3063 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3064 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3065 like OpenBSD, which has timer_settime but does not declare it.
3066 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3067 whether to use itimerspec-related primitives. All uses of
3068 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3070 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3072 * profiler.c (handle_profiler_signal): Fix a malloc race
3073 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3075 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3077 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3079 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3081 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3082 consistent with the change in return value of 'safe_strsignal'.
3084 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3086 Prefer plain 'static' to 'static inline' (Bug#12541).
3087 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3088 (bidi_set_sor_type, bidi_push_embedding_level)
3089 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3090 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3091 (bidi_cache_search, bidi_cache_ensure_space)
3092 (bidi_cache_iterator_state, bidi_cache_find)
3093 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3094 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3095 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3096 Now 'static', not 'static inline'.
3098 Count overruns when profiling; change units to ns.
3099 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3100 Give extra weight to samples after overruns, to attempt to count
3101 the time more accurately.
3102 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3103 the underlying primitives nominally do ns.
3104 (Fprofiler_cpu_start): Document the change. Mention that
3105 the sampling intervals are only approximate.
3107 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3109 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3111 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3112 case for the special 0 coding-system.
3114 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3115 (Fmake_overlay): Remove redundant tests.
3116 (fix_start_end_in_overlays): Remove redundant recentering.
3118 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3120 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3121 Update dependencies.
3123 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3125 Fix a malloc race condition involving strsignal.
3126 A signal can arrive in the middle of a malloc, and Emacs's signal
3127 handler can invoke strsignal, which can invoke malloc, which is
3128 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3129 Fix it by altering the signal handler so that it does not invoke
3131 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3132 * process.c (status_message): Use const pointer, in case strsignal
3133 is #defined to safe_strsignal.
3134 * sysdep.c (sys_siglist, init_signals): Always define and
3135 initialize a substitute sys_siglist if the system does not define
3136 one, even if HAVE_STRSIGNAL.
3137 (safe_strsignal): Rename from strsignal. Always define,
3138 using sys_siglist. Return a const pointer.
3139 * syssignal.h (safe_strsignal): New decl.
3140 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3142 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3144 * w32proc.c (timer_loop): Fix code that waits for timer
3145 expiration, to avoid high CPU usage.
3147 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3149 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3150 (sweep_weak_table): Remove redundant prototypes.
3152 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3154 * emacs.c: Move the inclusion of TERM_HEADER after including
3155 windows.h on WINDOWSNT. This avoids compilation problems with
3158 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3160 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3161 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3162 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3163 as the previous version used 'void *'.
3165 * ralloc.c (ROUNDUP): Fix last change.
3166 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3169 * w32proc.c <disable_itimers>: New static flag.
3170 (init_timers): Initialize it to zero, after creating the critical
3171 sections used by the timer threads.
3172 (term_timers): Set to 1 before deleting the critical sections.
3173 (getitimer, setitimer): If disable_itimers is non-zero, return an
3174 error indication without doing anything. Reported by Fabrice
3175 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3176 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3178 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3181 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3182 term_ntproc after all the other bookkeeping, to get timers working
3183 as long as possible.
3185 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3187 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3188 Suggested by Juri Linkov in
3189 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3191 Prefer plain 'static' to 'static inline' (Bug#12541).
3192 With static functions, modern compilers inline pretty well by
3193 themselves; advice from programmers often hurts as much as it helps.
3194 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3195 this change shrinks the text size of the Emacs executable by 1.1%
3196 without affecting CPU significantly in my benchmark.
3197 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3490 (handle_profiler_signal): Rename from sigprof_handler_1,
3491 for consistency with other handlers. Do not check whether
3492 cpu_log is a hash-table if garbage collecting, since it

3495 for consistency with other handlers.
3496 (setup_cpu_timer): New function, with much of what used to be in

3498 Prefer timer_settime if available, and prefer
3499 thread cputime clocks, then process cputime clocks, then
3500 monotonic clocks, to the old realtime clock. Use make_timeval
3501 to round more-correctly when falling back to setitimer.
3502 (Fprofiler_cpu_start): Use it.
3503 (Fprofiler_cpu_stop): Prefer timer_settime if available.

3722 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3723 (interruptible_wait_for_termination):
3724 Move these decls from lisp.h to syswait.h, since they use pid_t.
3725 Needed on FreeBSD; see Herbert J. Skuhra in
3726 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3727 * callproc.c: Include syswait.h.
3729 gnutls.c, gtkutil.c: Use bool for boolean.
3730 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)
3731 (emacs_gnutls_handle_error):
3732 * gtkutil.c (xg_check_special_colors, xg_prepare_tooltip)

3742 (update_frame_tool_bar, free_frame_tool_bar):
3743 * gtkutil.c, w32term.c, xterm.c (x_wm_set_size_hint):
3744 * nsmenu.m (ns_update_menubar):
3745 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
3746 * xfns.c (Fx_show_tip) [USE_GTK]:
3747 Use bool for boolean.
3748 * gtkutil.c (xg_update_frame_menubar):
3749 * xmenu.c (update_frame_menubar):
3750 Return void, not int, since caller ignores return value.
3751 * gtkutil.c (xg_change_toolbar_position):
3754 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3756 * makefile.w32-in (BLOCKINPUT_H): Remove.
3757 (SYSSIGNAL_H): New macro.

3773 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3775 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3776 fatal_error_backtrace.
3778 * w32proc.c (sys_kill): Undo last change: don't do anything when
3779 invoked to deliver SIGABRT to our own process. This is now
3780 handled by emacs_raise.
3782 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3784 * w32term.c (w32_read_socket): Remove leftover reference to
3785 interrupt_input_pending.
3787 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3789 Do not use SA_NODEFER.
3790 Problem reported by Dani Moncayo in
3791 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3793 * sysdep.c (emacs_abort): Do not reset signal handler.
3794 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3795 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3796 wanted even on POSIXish hosts, and it doesn't work on Windows.
3798 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3800 * xterm.c (x_term_init): Call fixup_locale before and after calling
3801 gtk_init (Bug#12392).
3803 2012-09-23 Chong Yidong <cyd@gnu.org>
3805 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3806 Vdynamic_library_alist.
3808 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3809 (Fgnutls_available_p): Caller changed.
3811 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3812 (Flibxml_parse_xml_region): Likewise.
3814 * dispextern.h (struct image_type): Remove arg from init function.
3816 * image.c (Finit_image_library, lookup_image_type)
3817 (define_image_type): Remove now-unneeded second arg.
3818 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3819 (init_tiff_functions, init_gif_functions, init_svg_functions):
3820 Arglist and w32_delayed_load calling convention changed.
3821 (gs_type): Remove init_gs_functions; there is no such function.
3822 (valid_image_p, make_image): Fix caller to lookup_image_type.
3824 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3826 Simplify and avoid signal-handling races (Bug#12471).
3828 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3829 Avoid recursive loop if there's a fatal error in the function itself.
3830 * atimer.c (pending_atimers):
3831 * blockinput.h: Don't include "atimer.h"; no longer needed.
3832 (interrupt_input_pending): Remove. All uses removed.
3833 pending_signals now counts both atimers and ordinary interrupts.
3834 This is less racy than having three separate pending-signal flags.
3835 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3837 Rename from their upper-case counterparts BLOCK_INPUT,
3838 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3839 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3840 This makes it easier to access volatile variables more accurately.
3841 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3842 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3843 that's more reliable if the code is buggy and sets
3844 interrupt_input_blocked to a negative value. All uses changed.
3845 * atimer.c (deliver_alarm_signal):
3846 Remove. No need to deliver this to the parent; any thread can
3847 handle this signal now. All uses replaced by underlying handler.
3848 * atimer.c (turn_on_atimers):
3849 * dispnew.c (handle_window_change_signal):
3850 * emacs.c (handle_danger_signal):
3851 * keyboard.c (kbd_buffer_get_event):
3852 Don't reestablish signal handler; not needed with sigaction.
3853 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3855 Rework to avoid unnecessary accesses to volatile variables.
3856 (UNBLOCK_INPUT_TO): Now a function.
3857 (totally_unblock_input, unblock_input): New decls.
3858 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3859 (init_data): Remove. Necessary stuff now done in init_signal.
3860 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3861 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3862 (fatal_error_code): Remove; no longer needed.
3863 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3864 it doesn't always backtrace. All uses changed. No need to reset
3865 signal to default, since sigaction and/or die does that for us now.
3866 Use emacs_raise (FOO), not kill (getpid (), FOO).
3867 (main): Check more-accurately whether we're dumping.
3868 Move fatal-error setup to sysdep.c
3869 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3870 * gtkutil.c (xg_get_file_name, xg_get_font):
3871 Remove no-longer-needed signal-mask manipulation.
3872 * keyboard.c, process.c (POLL_FOR_INPUT):
3873 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3874 * keyboard.c (read_avail_input): Remove.
3875 All uses replaced by gobble_input.
3876 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3877 (kbd_buffer_store_event_hold, gobble_input):
3878 (record_asynch_buffer_change) [USABLE_SIGIO]:
3879 (store_user_signal_events):
3880 No need to mess with signal mask.
3881 (gobble_input): If blocking input and there are terminals, simply
3882 set pending_signals to 1 and return. All hooks changed to not
3883 worry about whether input is blocked.
3884 (process_pending_signals): Clear pending_signals before processing
3885 them, in case a signal comes in while we're processing.
3886 By convention callers now test pending_signals before calling us.
3887 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3888 New functions, to support changes to blockinput.h.
3889 (handle_input_available_signal): Now extern.
3890 (reinvoke_input_signal): Remove. All uses replaced by
3892 (quit_count): Now volatile, since a signal handler uses it.
3893 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3894 All callers changed. Block SIGINT only if not already blocked.
3895 Clear sigmask reliably, even if Fsignal returns, which it can.
3896 Omit unnecessary accesses to volatile var.
3897 (quit_throw_to_read_char): No need to restore sigmask.
3898 * keyboard.c (gobble_input, handle_user_signal):
3899 * process.c (wait_reading_process_output):
3900 Call signal-handling code rather than killing ourselves.
3901 * lisp.h: Include <float.h>, for...
3902 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3903 (pending_signals): Now volatile.
3904 (syms_of_data): Now const if IEEE floating point.
3905 (handle_input_available_signal) [USABLE_SIGIO]:
3906 (terminate_due_to_signal, record_child_status_change): New decls.
3907 * process.c (create_process): Avoid disaster if memory is exhausted
3908 while we're processing a vfork, by tightening the critical section
3910 (send_process_frame, process_sent_to, handle_pipe_signal)
3911 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3913 (send_process): No need for setjmp/longjmp any more, since the
3914 SIGPIPE stuff is now gone. Instead, report an error if errno
3916 (record_child_status_change): Now extern. PID and W are now args.
3917 Return void, not bool. All callers changed.
3918 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3919 Remove. All uses removed. This bug should be fixed now in a
3921 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3922 and record the child status change directly. This avoids the
3923 need to futz with the signal mask.
3924 (process_fatal_action): Move here from emacs.c.
3925 (emacs_sigaction_flags): New function, containing
3926 much of what used to be in emacs_sigaction_init.
3927 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3928 caught by emacs, to make races less likely.
3929 (deliver_process_signal): Rename from handle_on_main_thread.
3931 (BACKTRACE_LIMIT_MAX): Now at top level.
3932 (thread_backtrace_buffer, threadback_backtrace_pointers):
3934 (deliver_thread_signal, deliver_fatal_thread_signal):
3935 New functions, for more-accurate delivery of thread-specific signals.
3936 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3937 (deliver_arith_signal): Handle in this thread, not
3938 in the main thread, since it's triggered by this thread.
3939 (maybe_fatal_sig): New function.
3940 (init_signals): New arg DUMPING so that we can be more accurate
3941 about whether we're dumping. Caller changed.
3942 Treat thread-specific signals differently from process-general signals.
3943 Block all signals while handling fatal error; that's safer.
3944 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3946 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3947 Ignore SIGPIPE unless batch.
3948 (emacs_backtrace): Output backtrace for the appropriate thread,
3949 which is not necessarily the main thread.
3950 * syssignal.h: Include <stdbool.h>.
3951 (emacs_raise): New macro.
3952 * xterm.c (x_connection_signal): Remove; no longer needed
3953 now that we use sigaction.
3954 (x_connection_closed): No need to mess with sigmask now.
3955 (x_initialize): No need to reset SIGPIPE handler here, since
3956 init_signals does this for us now.
3958 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3960 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3961 background rect may be larger (Bug#12245).
3963 2012-09-23 Chong Yidong <cyd@gnu.org>
3965 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3967 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3969 * .gdbinit: Just stop at fatal_error_backtrace.
3970 See Stefan Monnier's request in
3971 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3972 Remove no-longer-used query of system type.
3974 2012-09-22 Chong Yidong <cyd@gnu.org>
3976 * search.c (Freplace_match): Doc fix (Bug#12325).
3978 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3980 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3981 (Fline_end_position): Doc fix.
3983 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3985 2012-09-22 Chong Yidong <cyd@gnu.org>
3987 * dispextern.h (struct image_type): Add new slot, storing a type
3988 initialization function.
3990 * image.c (define_image_type): Call the image initializer function
3991 if it is defined. Arguments and return value changed.
3992 (valid_image_p, make_image): Callers changed.
3993 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3994 (gif_type, imagemagick_type, svg_type, gs_type):
3995 Add initialization functions.
3996 (Finit_image_library): Call lookup_image_type.
3997 (CHECK_LIB_AVAILABLE): Macro deleted.
3998 (lookup_image_type): Call define_image_type here, rather than via
3999 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4000 (syms_of_image): Move define_image_type calls for xbm_type and
4001 pbm_type to lookup_image_type.
4003 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4005 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4006 'idle_timers' from here ...
4007 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4008 lists, to avoid infloops when the timer does something stupid,
4009 like reinvoke itself with the same or smaller time-out.
4012 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4014 * window.c (Fsplit_window_internal): Handle only Qt value of
4015 Vwindow_combination_limit separately.
4016 (Qtemp_buffer_resize): New symbol.
4017 (Vwindow_combination_limit): New default value.
4020 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4022 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4023 the new overlay string. (Bug#10159)
4025 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4027 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4028 or that fprintf is async-signal-safe. POSIX doesn't require
4031 2012-09-22 Chong Yidong <cyd@gnu.org>
4033 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4036 2012-09-22 Kenichi Handa <handa@gnu.org>
4038 * composite.c (composition_reseat_it): Handle the case that a
4039 grapheme cluster is not covered by a single font (Bug#12352).
4041 2012-09-21 Chong Yidong <cyd@gnu.org>
4043 * image.c (define_image_type): Avoid adding duplicate types to
4044 image_types (Bug#12463). Suggested by Jörg Walter.
4046 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4048 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4049 (print_load_command_name): Add case LC_DATA_IN_CODE.
4050 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4052 2012-09-21 Glenn Morris <rgm@gnu.org>
4054 * eval.c (Frun_hook_with_args_until_success)
4055 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4057 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4059 * fileio.c (Ffile_selinux_context): Only call freecon when
4060 lgetfilecon succeeded.
4061 (Fset_file_selinux_context): Likewise. (Bug#12444)
4063 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4065 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4066 reordering, locate the cursor by calling set_cursor_from_row; if
4067 that fails, clear the desired glyph matrix before returning a
4068 failure indication to the caller. Fixes leaving garbled display
4069 when fast scrolling with a down-key. (Bug#12403)
4070 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4071 scrolling through multibyte text.
4073 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4075 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4076 calling mark_vectorlike since that's the one that marks the window.
4077 (mark_discard_killed_buffers): Mark the final cdr.
4078 * window.h (struct window): Move prev/next_buffers to the
4079 non-standard fields.
4080 * window.c (make_window): Initialize prev/next_buffers manually.
4082 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4084 Omit unused arg EXPECTED from socket hooks.
4085 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4086 * nsterm.m (ns_term_init):
4087 * termhooks.h (struct terminal.read_socket_hook):
4088 * w32inevt.c (w32_console_read_socket):
4089 * w32term.c (w32_read_socket):
4090 * xterm.c (XTread_socket):
4091 Omit unused arg EXPECTED. All callers changed.
4092 (store_user_signal_events): Return void, not int, since callers no
4093 longer care about the return value. All uses changed.
4095 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4097 * w32gui.h (XParseGeometry): Do not declare.
4099 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4101 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4102 Ignore 'expected'. See Eli Zaretskii in
4103 <http://bugs.gnu.org/12471#8> (last line).
4105 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4106 (XParseGeometry): Now static. Substitute extremal values for
4107 values that are out of range.
4109 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4111 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4113 * nsfns.m (XParseGeometry): Remove.
4114 (Fx_create_frame): Call x_set_offset to correctly interpret
4115 top_pos in geometry.
4117 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4118 (Fx_parse_geometry): If there is a space in string, call
4119 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4121 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4123 * search.c (scan_buffer): Use character positions in calls to
4124 region_cache_forward and region_cache_backward, not byte
4125 positions. (Bug#12196)
4127 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4128 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4130 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4131 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4132 emacs_blocked_malloc, now deleted.
4134 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4136 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4137 The workaround was for improving performance on Solaris 2.4, but
4138 is getting in the way now. Emacs will still work if someone is
4139 still running Solaris 2.4 in a museum somewhere; Sun dropped
4140 support for Solaris 2.4 in 2003.
4141 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4142 * process.c (create_process) [HAVE_WORKING_VFORK]:
4143 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4144 since Emacs no longer uses vfork on that platform.
4146 2012-09-17 Glenn Morris <rgm@gnu.org>
4148 * emacs.c: Use COPYRIGHT.
4150 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4152 Remove configure's --without-sync-input option (Bug#12450).
4153 When auditing signal-handling in preparation for cleaning it up,
4154 I found that SYNC_INPUT has race conditions and would be a real
4155 pain to fix. Since it's an undocumented and deprecated
4156 configure-time option, now seems like a good time to remove it.
4157 Also see <http://bugs.gnu.org/11080#16>.
4158 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4159 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4160 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4161 (malloc_hysteresis):
4162 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4163 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4164 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4165 (dont_register_blocks, bytes_used_when_reconsidered)
4166 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4167 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4168 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4169 Remove. All uses removed.
4170 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4171 implementation, one that depends on whether the new macro
4172 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4174 * atimer.c (run_timers, handle_alarm_signal):
4175 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4176 (handle_async_input, process_pending_signals)
4177 (handle_input_available_signal, init_keyboard):
4178 * nsterm.m (ns_read_socket):
4179 * process.c (wait_reading_process_output):
4180 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4181 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4183 * xterm.c (XTread_socket):
4185 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4186 * eval.c (handling_signal): Remove. All uses removed.
4187 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4188 All uses replaced with the SYNC_INPUT version.
4189 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4191 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4194 * font.c (Ffont_shape_gstring): Remove unused local.
4196 2012-09-16 Glenn Morris <rgm@gnu.org>
4198 * Makefile.in (clean): No longer run nextstep's clean.
4200 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4202 (ns-app): Move here from ns.mk, and simplify.
4203 (clean): Simplify nextstep entry.
4204 * ns.mk: Remove file.
4206 2012-09-17 Kenichi Handa <handa@gnu.org>
4208 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4209 not covert the last few charactes.
4211 2012-09-16 Kenichi Handa <handa@gnu.org>
4213 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4214 here, but just check the validity of glyphs in the glyph-string.
4216 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4218 * window.c (Fwindow_parameter, Fset_window_parameter):
4219 Accept any window as argument (Bug#12452).
4221 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4223 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4224 to ns_term_init to avoid memory leak.
4226 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4227 explicit retain/release.
4228 (ns_term_init): Only allow one display. Initialize outerpool and
4231 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4233 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4234 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4235 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4236 the Microsoft problem in a different way, by altering ../nt/config.nt.
4238 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4253 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4254 by lisp.h. This completes removal of setjmp.h inclusion
4255 erroneously announced in the previous commit. (Bug#12446)
4257 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4260 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4261 not defined as a macro. The latter happens on MS-Windows.
4264 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4266 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4267 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4268 Some instances of '#include <setjmp.h>' removed, if the
4269 only reason for the instance was because "lisp.h" was included.
4270 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4271 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4272 and _longjmp with the new symbols. Emacs already uses _setjmp if
4273 available, so this change affects only POSIXish hosts that have
4274 sigsetjmp but not _setjmp, such as some versions of Solaris and
4275 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4276 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4277 (png_load_body) [HAVE_PNG]:
4278 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4279 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4280 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4281 since PNG requires jmp_buf. This is the only exception to the
4282 general rule that we now use sys_setjmp and sys_longjmp.
4283 This exception is OK since this code does not change the signal
4284 mask or longjmp out of a signal handler.
4286 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4288 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4289 Include "syssignal.h", for 'main_thread'.
4291 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4293 Avoid out-of-range marker position (Bug#12426).
4294 * insdel.c (replace_range, replace_range_2):
4295 Adjust markers before overlays, as suggested by comments.
4296 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4297 Remove redundant check before calling offset_intervals.
4299 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4301 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4302 current buffer (Bug#12387).
4304 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4306 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4308 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4310 Use a more backwards-compatible timer format (Bug#12430).
4311 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4312 vector element, not from the 4th, since PSECS is now at the end.
4313 (Fcurrent_idle_time): Doc fix.
4315 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4317 Function to mark objects and remove killed buffers at once.
4318 * alloc.c (discard_killed_buffers): Rename to ...
4319 (mark_discard_killed buffers) ... new name. Add marking
4320 of remaining objects. Fix comment. Adjust users.
4321 (mark_object): Do not touch frame buffer lists here.
4322 * frame.c (delete_frame): Reset frame buffer lists here.
4324 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4326 Better workaround for GNOME bug when --enable-gcc-warnings.
4327 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4328 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4329 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4331 Simplify SIGIO usage (Bug#12408).
4332 The code that dealt with SIGIO was crufty and confusing, e.g., it
4333 played tricks like "#undef SIGIO" but these tricks were not used
4334 consistently. Simplify mostly by not #undeffing standard symbols,
4335 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4336 or not as we please) rather than "defined SIGIO" (standard symbol
4337 that we probably shouldn't #undef).
4338 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4339 Modules that need it can include it.
4340 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4341 * dispextern.h (ignore_sigio): New decl.
4342 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4343 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4344 * emacs.c (shut_down_emacs):
4345 * keyboard.c (kbd_buffer_store_event_hold):
4346 Use ignore_sigio rather than invoking 'signal' directly.
4347 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4349 (FIONREAD, SIGIO): Do not #undef.
4350 (tty_read_avail_input): Use #error rather than a syntax error.
4351 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4352 for I_PIPE, used by SETUP_SLAVE_PTY.
4353 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4354 * sysdep.c (croak): Remove; no longer needed. This bit of
4355 temporary code, with Fred N. Fish's comment that it's temporary,
4356 has been in Emacs since at least 1992!
4357 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4358 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4359 * syssignal.h (croak): Remove decl.
4360 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4361 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4362 now that we're termios-only.
4363 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4364 * term.c (dissociate_if_controlling_tty): Use #error rather than
4367 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4368 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4369 to work around GNOME bug 683906.
4370 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4371 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4372 This works around GCC bug 54561.
4374 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4376 More fixes for 'volatile' and setjmp/longjmp.
4377 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4378 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4379 (png_load_body) [HAVE_PNG]:
4380 (jpeg_load_body) [HAVE_JPEG]:
4381 New function, with most of the old parent function's body.
4382 (png_load) [HAVE_PNG]:
4383 (jpeg_load) [HAVE_JPEG]:
4384 Invoke the new function, to avoid longjmp munging our locals.
4385 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4386 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4387 longjmp is passed 2, as the C standard doesn't guarantee this.
4388 Instead, store the failure code into mgr->failure_code.
4390 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4392 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4393 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4394 (syms_of_keyboard): Remove support for unread-command-char.
4396 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4398 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4399 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4400 violation. (Bug#12426)
4402 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4404 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4406 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4408 * eval.c: Add `inhibit-debugger'.
4409 (Qinhibit_debugger): New symbol.
4410 (call_debugger): Bind it instead of Qdebug_on_error.
4411 (maybe_call_debugger): Test Vinhibit_debugger.
4412 (syms_of_eval): Define inhibit-debugger.
4413 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4414 (syms_of_xdisp): Remove inhibit-debug-on-message.
4416 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4418 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4419 If a nonvolatile local variable is written before a _longjmp to
4420 the frame containing the variable, and is read after the _longjmp,
4421 the value read is indeterminate. Some local variables of type
4422 'struct handler' and 'struct catchtag' are used in this way, so
4423 mark each of their slots as volatile if the slot can be set before
4424 _longjmp and read afterwards.
4425 * lisp.h (struct handler): var and chosen_clause are now volatile.
4426 (struct catchtag): val, next, and pdlcount are now volatile.
4428 * bidi.c (bidi_push_it, bidi_pop_it):
4429 * fns.c (copy_hash_table):
4430 * image.c (define_image_type):
4431 * keyboard.c (kbd_buffer_store_event_hold):
4432 * process.c (Fprocess_send_eof):
4433 * xfaces.c (x_create_gc) [HAVE_NS]:
4434 * xgselect.c (xg_select):
4435 Prefer assignment to memcpy when either will do.
4437 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4438 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4439 time an item is removed. No need to mark this function 'inline';
4440 the compiler knows better than we do.
4442 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4444 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4445 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4446 to change_frame_size (Bug#12388).
4447 (windowDidResize:): Pass YES to updateFrameSize.
4449 * nsterm.h: Add delay parameter to updateFrameSize.
4451 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4453 Discard killed buffers from deleted window and frame objects.
4454 This reduces an amount of references to killed buffers and
4455 helps GC to reclaim them faster.
4456 * alloc.c (discard_killed_buffers): New function.
4457 (mark_object): Use it for deleted windows and frames.
4458 (mark_object): If symbol's value is set up for a killed buffer
4459 or deleted frame, restore its global binding.
4460 * data.c (swap_in_global_binding): Add GC notice.
4461 (swap_in_symval_forwarding): Use convenient set_blv_where.
4462 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4463 * window.h: ... to here.
4465 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4467 Convenient macro to check whether the buffer is live.
4468 * buffer.h (BUFFER_LIVE_P): New macro.
4469 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4470 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4472 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4474 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4475 composition cases (Bug#12364).
4477 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4478 overhang of succeeding glyphs overlapping box cursor.
4480 * w32term.c (x_draw_glyph_string): Likewise.
4482 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4484 Simplify, document, and port floating-point (Bug#12381).
4485 The porting part of this patch fixes bugs on non-IEEE platforms
4486 with frexp, ldexp, logb.
4487 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4489 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4490 support, by removing commented-out code and briefly listing the
4491 C89 functions excluded. The commented-out stuff was confusing
4492 maintenance, e.g., we thought we needed cbrt but it was commented out.
4493 (logb): Remove decl; no longer needed.
4494 (isfinite): New macro, if not already supplied.
4495 (isnan): Don't replace any existing macro.
4496 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4497 are present on all C89 platforms.
4498 (Ffrexp): Do not special-case zero, as frexp does the right thing
4500 (Flogb): Do not use logb, as it doesn't have the desired meaning
4501 on hosts that use non-base-2 floating point. Instead, stick with
4502 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4503 frexp, to avoid getting an unspecified result.
4505 * xdisp.c (Qinhibit_debug_on_message): Now static.
4507 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4509 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4510 NSBezierPath (Bug#12131).
4512 2012-09-10 Chong Yidong <cyd@gnu.org>
4514 * fns.c (Fdelq, Fdelete): Doc fix.
4516 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4518 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4519 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4521 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4523 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4524 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4527 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4529 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4530 left fringe if the window has a left margin. This avoids leaving
4531 traces of the cursor because its leftmost pixel is not drawn over.
4533 * dispnew.c (update_window_line): When the left margin area of a
4534 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4535 that screen line. (Bug#12277)
4537 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4539 Assume C89 or later for math functions (Bug#12381).
4540 This simplifies the code, and makes it a bit smaller and faster,
4541 and (most important) makes it easier to clean up signal handling
4542 since we can stop worring about floating-point exceptions in
4543 library code. That was a problem before C89, but the problem
4544 went away many years ago on all practical Emacs targets.
4545 * data.c, image.c, lread.c, print.c:
4546 Don't include <math.h>; no longer needed.
4547 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4548 might be autoconfigured, as that never happens.
4550 * doprnt.c (DBL_MAX_10_EXP):
4551 * print.c (DBL_DIG):
4552 Remove. C89 or later always defines these.
4553 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4554 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4555 (arith_error, domain_error, domain_error2):
4556 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4557 no longer needed -- we simply return what C returns. All uses removed.
4558 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4560 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4561 Remove. All uses expanded, as these macros are no longer used
4562 more than once and are now more trouble than they're worth.
4563 (Ftan): Use tan, not sin / cos.
4564 (Flogb): Assume C89 frexp.
4565 (fmod_float): Assume C89 fmod.
4566 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4567 (init_floatfns): Remove. All uses removed.
4569 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4571 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4572 compositeToPoint for OSX < 10.6 (Bug#12390).
4574 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4576 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4577 This produces more-accurate results.
4579 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4581 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4582 changes (Bug#12088).
4584 2012-09-08 Chong Yidong <cyd@gnu.org>
4586 * syntax.c (Fstring_to_syntax): Doc fix.
4588 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4590 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4591 in the internal border.
4592 (x_set_window_size): Remove static variables and their usage.
4593 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4594 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4595 Remove fringe/internal border adjustment (Bug#11052).
4596 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4597 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4598 (ns_fix_rect_ibw): Remove.
4599 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4600 (ns_dumpglyphs_box_or_relief): Ditto.
4601 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4603 (ns_dumpglyphs_image): Ditto.
4604 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4606 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4607 their usage. Add fringe_extended_p and its use as in other terms.
4608 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4609 scroll bar was removed.
4610 (updateFrameSize): New function.
4611 (windowDidResize): Move code to updateFrameSize and call it.
4613 * nsterm.h (EmacsView): Add updateFrameSize.
4615 2012-09-07 Chong Yidong <cyd@gnu.org>
4617 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4619 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4621 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4623 More signal-handler cleanup (Bug#12327).
4624 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4625 Problem introduced when merging patches. Noted by Eli Zaretskii in
4626 <http://bugs.gnu.org/12327#67>.
4627 * floatfns.c: Comment fix.
4628 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4629 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4630 and anyway the declaration is harmless even if SIGDANGER is not defined.
4631 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4632 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4633 source files not surprisingly expected syssignal.h to define, or
4634 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4635 Include <sys/ioctl.h>, for FIONREAD.
4636 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4637 This eliminates a problem whereby other files mysteriously had
4638 to include "syssignal.h" before including "systty.h" if they
4639 wanted to use "#ifdef SIGIO".
4641 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4643 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4645 * w32.c (sigemptyset): Empty the set.
4646 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4648 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4650 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4652 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4653 (mark_object): Likewise for frame objects.
4655 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4657 * syssignal.h (handle_on_main_thread): Always declare,
4658 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4659 This ports to platforms without HAVE_PTHREAD.
4661 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4663 Signal-handler cleanup (Bug#12327).
4664 Emacs's signal handlers were written in the old 4.2BSD style with
4665 sigblock and sigmask and so forth, and this led to some
4666 inefficiencies and confusion. Rewrite these to use
4667 pthread_sigmask etc. without copying signal sets around. Also,
4668 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4669 'signal', and instead use functions that do not attempt to take
4670 over the system name space. This patch causes Emacs's text
4671 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4672 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4673 Do not include <signal.h> or "syssignal.h", as these
4674 modules do not use signals.
4675 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4676 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4677 Do not include <signal.h>, as "syssignal.h" does that for us now.
4678 * atimer.c (sigmask_atimers): New function.
4679 (block_atimers, unblock_atimers): New functions,
4680 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4682 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4683 no longer needed here.
4684 * emacs.c (main): Inspect existing signal handler with sigaction,
4685 so that there's no need to block and unblock SIGHUP.
4686 * sysdep.c (struct save_signal): New member 'action', replacing
4687 old member 'handler'.
4688 (save_signal_handlers, restore_signal_handlers):
4689 Use sigaction instead of 'signal' to save and restore.
4690 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4691 New function. All users of 'signal' modified to use set_sighandler
4692 if they're writeonly, and to use sys_signal if they're read+write.
4693 (emacs_sigaction_init, forwarded_signal): New functions.
4694 (sys_signal): Remove. All uses replaced by calls to sigaction
4695 and emacs_sigaction_init, or by direct calls to 'signal'.
4696 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4697 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4698 all uses replaced by pthread_sigmask etc. calls.
4699 * syssignal.h: Include <signal.h>.
4700 (emacs_sigaction_init, forwarded_signal): New decls.
4701 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4702 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4703 (sigmask, sys_sigmask): Remove; no longer needed.
4704 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4705 (sigblock, sigunblock, sigfree):
4706 (sigsetmask) [!defined sigsetmask]:
4707 Remove. All uses replaced by pthread_sigmask.
4708 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4709 no longer need to be replaced, and its typical old uses
4710 are now done via emacs_sigaction_init and sigaction.
4711 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4712 (sys_sigdel): Remove; unused.
4713 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4715 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4717 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4718 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4720 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4722 Explicitly mark buffer_defaults and buffer_local_symbols.
4723 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4724 mark_local_symbols here.
4725 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4726 since special buffers aren't marked here any more.
4727 (allocate_buffer): Chain new buffer with all_buffers here...
4728 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4730 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4731 (syms_of_buffer): Remove staticpro of the above.
4732 (init_buffer_once): Set names for buffer_defaults and
4733 buffer_local_symbols.
4735 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4737 Use bool for booleans in font-related modules.
4738 * font.c (font_intern_prop, font_style_to_value)
4739 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4740 (generate_otf_features, font_check_otf_features, font_check_otf)
4741 (font_match_p, font_list_entities, font_at):
4742 * fontset.c (fontset_id_valid_p, reorder_font_vector
4743 (fontset_find_font, Fset_fontset_font)
4744 (face_suitable_for_char_p) [0]:
4745 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4746 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4747 (m17n_flt_initialized, ftfont_shape_by_flt):
4748 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4749 * nsfont.m (nsfont_draw):
4750 * w32font.c (w32font_draw):
4751 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4752 Use bool for booleans.
4753 * font.h: Adjust to above API changes.
4754 (struct font, struct font_driver, struct font_driver_list):
4755 Use bool for booleans.
4756 (struct font): Remove useless member encoding_type.
4758 * fontset.c, xftfont.c: Omit unnecessary static decls.
4760 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4762 * alloc.c (mark_object): Revert window marking code
4763 since it's unsafe for the Fset_window_configuration.
4765 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4767 Fix race conditions with signal handlers and errno (Bug#12327).
4768 Be more systematic about preserving errno whenever a signal
4769 handler returns, even if it's not in the main thread. Do this by
4770 renaming signal handlers to distinguish between signal delivery
4771 and signal handling. All uses changed.
4772 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4773 * data.c (deliver_arith_signal): Rename from arith_error.
4774 * dispnew.c (deliver_window_change_signal): Rename from
4775 window_change_signal.
4776 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4777 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4778 * keyboard.c (deliver_input_available_signal): Rename from
4779 input_available_signal.
4780 (deliver_user_signal): Rename from handle_user_signal.
4781 (deliver_interrupt_signal): Rename from interrupt_signal.
4782 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4783 (deliver_child_signal): Rename from sigchld_handler.
4784 * atimer.c (handle_alarm_signal):
4785 * data.c (handle_arith_signal):
4786 * dispnew.c (handle_window_change_signal):
4787 * emacs.c (handle_fatal_signal, handle_danger_signal):
4788 * keyboard.c (handle_input_available_signal):
4789 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4790 * process.c (handle_pipe_signal, handle_child_signal):
4791 New functions, with the actual signal-handling code taken from the
4792 original respective signal handlers, sans the sporadic attempts to
4793 preserve errno, since that's now done by handle_on_main_thread.
4794 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4795 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4796 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4798 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4799 Move initialization of main_thread to sysdep.c's init_signals.
4800 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4801 our usage, and simplifies the mainline code.
4802 (record_child_status_change): New static function, as a helper
4803 for handle_child_signal, and with most of the old child handler's
4805 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4806 (handle_child_signal): Use the above.
4807 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4808 Moved here from emacs.c.
4809 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4810 code moved here from emacs.c's main function.
4811 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4812 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4813 This lets callers save and restore errno properly.
4815 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4817 Remove redundant or unused things here and there.
4818 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4819 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4820 * editfns.c (Fcompare_buffer_substrings): Likewise.
4821 * frame.h (struct terminal, struct font_driver_list):
4822 Remove redundant declarations.
4823 * window.h (Qleft, Qright): Likewise.
4825 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4827 Do not mark objects from deleted buffers, windows and frames.
4828 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4829 (mark_object): Likewise for windows and frames.
4831 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4833 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4834 buffer_defaults and buffer_local_symbols as valid objects.
4835 Return special value to denote them.
4837 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4839 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4840 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4841 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4842 (file_name_absolute_p, Fsubstitute_in_file_name):
4843 (check_executable, check_writable, Ffile_accessible_directory_p)
4844 (Fset_file_selinux_context, Fdefault_file_modes)
4845 (Finsert_file_contents, choose_write_coding_system)
4846 (Fwrite_region, build_annotations, a_write, e_write)
4848 * filelock.c (boot_time_initialized, get_boot_time)
4849 (get_boot_time_1, lock_file_1, within_one_second):
4850 * floatfns.c (in_float):
4851 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4852 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4853 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4854 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4855 * window.c (compare_window_configurations):
4856 Use bool for booleans.
4857 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4858 (Fdefault_file_modes): Now mode_t, not int, for modes.
4859 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4860 (internal_delete_file): Now returns void, not a (boolean) int,
4861 since nobody was looking at the return value.
4862 * lisp.h, window.h: Adjust to above API changes.
4864 * xdisp.c (set_message): Simplify and reindent last change.
4866 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4868 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4870 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4872 * eval.c (call_debugger): Make the function non-static so that we
4873 can call it from set_message.
4875 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4876 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4878 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4880 Give more-useful info on a fatal error (Bug#12328).
4881 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4882 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4883 of doing the work ourselves.
4884 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4885 do most of the work.
4886 (fatal_error_backtrace): New function, taken from the guts
4887 of the old fatal_error_signal, but with a new option to output
4889 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4890 info about the signal than just its number.
4891 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4892 * sysdep.c: Include <execinfo.h>
4893 (emacs_backtrace): New function, taken partly from the previous
4894 code of the 'die' function.
4895 (emacs_abort): Call fatal_error_backtrace rather than abort.
4897 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4899 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4900 eager (load-time) macro-expansion.
4901 * lisp.mk (lisp): Add macroexp.
4903 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4905 Simplify redefinition of 'abort' (Bug#12316).
4906 Do not try to redefine the 'abort' function. Instead, redo
4907 the code so that it calls 'emacs_abort' rather than 'abort'.
4908 This removes the need for the NO_ABORT configure-time macro
4909 and makes it easier to change the abort code to do a backtrace.
4910 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4911 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4912 Remove; sysdep.c's emacs_abort now takes its place.
4913 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4914 'abort' changed to use 'emacs_abort'.
4915 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4916 (abort) [!defined abort]: Rename to ...
4917 (emacs_abort): ... new name.
4918 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4919 the place of the old 'abort' in emacs.c.
4920 * w32.c, w32fns.c (abort): Do not #undef.
4921 * w32.c (emacs_abort): Rename from w32_abort.
4923 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4925 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4926 offsets[j].dv, since the y axis of the screen coordinates points
4927 down, while the y axis of the font definition coordinates points
4928 up. This fixes display of Arabic diacritics such as KASRA and
4929 KASRATAN. (Bug#11860)
4931 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4933 Be more systematic about _setjmp vs setjmp.
4934 * alloc.c (test_setjmp, mark_stack):
4935 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4936 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4937 (png_load, my_error_exit, jpeg_load):
4938 * process.c (send_process_trap, send_process):
4939 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4940 The underscored versions are up to 30x faster on some hosts.
4941 Formerly, the code used setjmp+longjmp sometimes and
4942 _setjmp+_longjmp at other times, with no particular reason to
4943 prefer setjmp+longjmp.
4945 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4947 Fix minor problem found by static checking.
4948 * buffer.c (Fdelete_all_overlays): Return nil.
4950 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4952 * buffer.c (Fdelete_all_overlays): New function.
4954 2012-09-03 Chong Yidong <cyd@gnu.org>
4956 * gtkutil.c: Add extern decl for Qxft.
4958 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4960 * emacs.c, eval.c: Use bool for boolean.
4961 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4962 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4963 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4964 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4965 (main, decode_env_path, Fdaemon_initialized):
4966 * eval.c (call_debugger, Finteractive_p, interactive_p):
4967 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4968 (maybe_call_debugger, Fbacktrace):
4969 * process.c (read_process_output, exec_sentinel):
4970 Use bool for booleans.
4971 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4972 All callers changed.
4973 * eval.c (interactive_p): Omit always-true boolean argument
4974 EXCLUDE_SUBRS_P. All callers changed.
4975 * dispextern.h, lisp.h: Reflect above API changes.
4976 * firstfile.c (dummy): Use the address of 'main', whose signature
4977 won't change, instead of the address of 'initialize', whose
4978 signature just changed from int to bool.
4979 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4980 * msdos.c (fatal_error_in_progress): ... from here.
4981 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4983 (redisplay_internal, unwind_redisplay): Simply clear
4984 REDISPLAYING_P when unwinding, instead of saving its previous,
4985 always-false value and then restoring it.
4987 Clean up some extern decls.
4988 Mostly, this hoists extern decls out of .c files and into .h files.
4989 That way, we're more likely to catch errors if the interfaces change.
4990 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4991 declare xg_mark_data.
4992 * dispextern.h (x_frame_parm_handlers):
4994 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4995 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4996 (Qultra_bold, Qoblique, Qitalic):
4997 Move extern decl here from .c file.
4998 * alloc.c (xg_mark_data) [USE_GTK]:
5000 * eval.c (Qlexical_binding):
5001 * fns.c (time) [!HAVE_UNISTD_H]:
5002 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
5003 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
5004 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
5005 * lread.c (Qinternal_interpreter_environment):
5006 * minibuf.c (Qbuffer):
5007 * process.c (QCfamily, QCfilter):
5008 * widget.c (free_frame_faces):
5009 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5010 * xfont.c (x_clear_errors):
5011 * xterm.c (x_frame_parm_handlers):
5012 Remove now-redundant extern decls.
5013 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5014 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5016 * xfaces.c: Remove unnecessary static decls.
5017 * xterm.c (updating_frame): Remove decl of nonexistent object.
5019 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5020 when building globals.h, as the objects that are not built on
5021 this host are not needed to compile C files on this host.
5023 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>

5077 offset adjustment values separately for each cluster. (Bug#11860)
5079 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5080 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5081 about implicit conversions from integer to pointer.

5139 window system declarations.
5141 * frame.h: Move common functions here: set_frame_menubar,
5142 x_set_window_size, x_sync, x_get_focus_frame,
5143 x_set_mouse_position, x_set_mouse_pixel_position,
5144 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5201 for GCC 4.7.1 x86-64.
5203 2012-08-30 Glenn Morris <rgm@gnu.org>
5205 * lread.c (init_lread): For out-of-tree builds, only add the
5206 source directory's site-lisp dir to the load-path if it exists,
5207 consistent with in-tree builds. (Bug#12302)
5209 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

5230 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5231 Add window_closed and button_values. Add void as return value for
5232 add(Button|String|Split). addButton takes int instead of Lisp_Object.

5439 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5440 are all boolean, so make them single-bit bitfields.
5442 * lisp.h (ASET): Remove attempt to detect side effects.
5443 It was meant to be temporary and it often doesn't work,
5444 because when IDX has side effects the behavior of IDX==IDX
5445 is undefined. See Stefan Monnier in
5446 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5448 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

5451 (FUNCTIONP): Use it.
5452 * eval.c (Ffunctionp): Use it.
5454 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5456 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5457 as that's faster and simpler than static storage. Don't bother
5458 with the g_main_context_query overhead if g_main_context_pending
5459 says no events are pending.
5460 (gfds, gfds_size): Remove these static vars.
5461 (xgselect_initialize): Remove; no longer needed.
5462 All uses and decls removed.
5464 * emacs.c (fatal_error_signal_hook): Remove.

5476 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5478 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5480 On assertion failure, print backtrace if available.
5481 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5482 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5483 * Makefile.in (LIB_EXECINFO): New macro.
5486 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5487 * bytecode.c (exec_byte_code):
5488 * callint.c (check_mark, Fcall_interactively):
5489 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5490 (getenv_internal, sync_process_alive, call_process_exited):
5491 * lisp.h (USE_SAFE_ALLOCA):
5492 Use bool for booleans, instead of int.
5493 * lisp.h, process.h: Adjust prototypes to match above changes.
5494 * callint.c (Fcall_interactively): Don't assume the mark's
5495 offset fits in 'int'.
5497 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5499 * buffer.c, buffer.h: Use bool for boolean.
5500 * buffer.c (reset_buffer_local_variables)
5501 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5502 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
5503 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
5504 (overlay_touches_p, overlay_strings, Foverlay_put)
5505 (report_overlay_modification, call_overlay_mod_hooks):
5506 (mmap_enlarge, mmap_set_vars):
5507 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5508 Use bool for booleans, instead of int.
5509 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5510 since the 1-or-0 return value is always ignored anyway.
5511 (mmap_initialized_p):
5512 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5513 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5515 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5517 * bidi.c: Use bool for boolean.
5518 This is a bit more readable, and makes the text segment of bidi.o
5519 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5520 Presumably it's faster too.
5521 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5523 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5524 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5525 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5526 (bidi_explicit_dir_char, bidi_level_of_next_char)
5527 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5528 Use bool for booleans, instead of int.
5529 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5530 (bidi_unshelve_cache): Adjust decls to match code.
5532 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5534 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5537 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5539 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5540 * atimer.h: Include <stdbool.h>.
5542 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5544 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5545 compile time tests instead of run time tests on systems that do
5547 (FRAME_MAC_P): Remove leftover from deleted code.
5548 * frame.c (syms_of_frame): Remove leftover from deleted code.
5550 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5552 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5554 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5556 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5557 Otherwise, the compiler complains about (A?B:C) where B is void
5558 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5559 (fontset_add): Return void, for FONTSET_ADD.
5561 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5563 * alloc.c: Use bool for booleans.
5564 (gc_in_progress, abort_on_gc)
5565 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5566 (dont_register_blocks) [GC_MALLOC_CHECK]:
5567 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5568 (check_string_bytes, make_specified_string, memory_full)
5569 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5570 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5571 (mark_stack, valid_pointer_p, make_pure_string)
5572 (Fgarbage_collect, survives_gc_p, gc_sweep):
5573 Use bool for booleans, instead of int.
5574 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5575 Remove unused local.
5576 * alloc.c (PURE_POINTER_P):
5577 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5578 * editfns.c (Fformat):
5579 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5581 * fns.c (sweep_weak_table):
5582 * lisp.h (suppress_checking, push_message, survives_gc_p)
5583 (make_pure_string, gc_in_progress, abort_on_gc):
5584 * lread.c (readchar, read1):
5585 * print.c (Fprin1_to_string):
5586 * xdisp.c (push_message):
5587 Use bool for booleans affected directly or indirectly by
5590 Make recently-introduced setters macros.
5591 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5592 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5593 (set_fontset_default, set_fontset_fallback): Rename from their
5594 upper-case counterparts, and make them functions rather than macros.
5595 This is more consistent with the other recently-introduced setters.
5596 These don't need to be inline, since they're local.
5598 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5600 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5601 the loop (Bug#12247).
5603 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5605 * lisp.h (vcopy): Use memcpy rather than our own loop.
5606 This fixes a performance regression introduced by the recent
5607 addition of vcopy. This means 'vcopy' will need to be modified
5608 for a copying collector, but that's OK. Also, tighten the
5609 checking in the assertion.
5611 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5613 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5614 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5615 non-base glyph for the width of the base character, according to
5616 what x_draw_composite_glyph_string_foreground expects.
5617 Generate WADJUST value according to composition_gstring_width's
5618 expectations, to produce correct width of the composed character.
5619 Reverse the sign of the DU offset produced by ScriptPlace.
5621 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5623 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5625 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5627 Avoid direct writes to contents member of struct Lisp_Vector.
5628 * lisp.h (vcopy): New function to copy data into vector.
5629 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5630 * fns.c (Ffillarray): Use ASET.
5631 * keyboard.c (timer_check_2): Use AREF and ASET.
5632 (append_tool_bar_item, Frecent_keys): Use vcopy.
5633 * lread.c (read_vector): Use ASET.
5634 * msdos.c (Frecent_doskeys): Use vcopy.
5635 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5636 (Finternal_merge_in_global_face): Use ASET and vcopy.

5642 the position of its buffer's point.
5643 (Fset_window_point): For the selected window always go in its
5644 buffer to the specified position.
5646 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5648 Setter macros for fontsets.
5649 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5650 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5651 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5654 2012-08-20 Glenn Morris <rgm@gnu.org>
5656 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5657 Don't assume that `ln -f' works.
5659 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5661 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5662 and later about non-assignments with no effect. See discussion at
5663 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5666 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5668 Inline setter functions for Lisp_Objects slots of struct specbinding.
5669 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5672 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5674 * window.c (select_window): Always make selected window's buffer
5677 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5679 Use AREF and ASET for docstrings of category tables.
5680 * category.h (CATEGORY_DOCSTRING): Use AREF.
5681 (SET_CATEGORY_DOCSTRING): Use ASET.
5682 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5684 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5686 Inline setter functions for hash table members.
5687 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5688 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5689 (set_hash_key_and_value, set_hash_index, set_hash_next)
5690 (set_hash_hash): New functions.
5691 * charset.c, fns.c: Adjust users.
5693 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5695 Inline getter and setter functions for per-buffer values.
5696 * buffer.h (per_buffer_default, set_per_buffer_default)
5697 (per_buffer_value, set_per_buffer_value): New functions.
5698 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5699 * buffer.c, data.c: Adjust users.
5701 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5703 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5705 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5707 Rely on <config.h> + <unistd.h> to declare 'environ',
5708 as gnulib does this if the system doesn't.
5709 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5710 Remove declaration. MS-Windows declares it on stdlib.h which is
5711 included by conf_post.h.
5712 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5713 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5714 * vm-limit.c: Include <unistd.h>, for 'environ'.
5716 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5717 (start_of_data): Remove decl; mem-limits.h provides it.
5719 * xdisp.c (handle_invisible_prop): Make it a bit faster
5720 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5722 2012-08-19 Chong Yidong <cyd@gnu.org>
5724 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5727 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5729 * .gdbinit: Use call instead of set when calling a function in the
5732 * data.c (set_internal): Don't use set_blv_found.
5733 (Fkill_local_variable): Likewise.
5735 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5737 * nsfont.m (ns_ascii_average_width): Ensure the string
5738 ascii_printable is initialized with a null-terminated character
5739 array. Otherwise, it can contain undesired extra characters.
5741 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5743 port new setting code to Sun C 5.8 2005/10/13
5744 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5745 Return void, not Lisp_Object. Otherwise, the compiler
5746 complains about (A?B:C) where B is void and C is Lisp_Object
5747 when compiling CHAR_TABLE_SET, due to the recent change to
5748 the API of sub_char_table_set_contents.
5750 2012-08-18 Chong Yidong <cyd@gnu.org>
5752 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5753 for the string case (Bug#3874).

6581 * w32.c (init_environment): Change the default values of many
6582 environment variables in dflt_envvars[] to NULL, to avoid pushing
6583 them into environment when they were not already defined.
6584 Remove the code that deletes site-lisp subdirectories from the default
6585 value of EMACSLOADPATH, as it is no longer needed.
6586 (check_windows_init_file): Now external, not static.
6587 Use Vload_path as is, without adding anything, as this function is now
6588 called when Vload_path is already set up.
6590 * w32.h (check_windows_init_file): Add prototype.
6592 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6635 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6636 Remove unnecessary pointer casts.
6637 * alloc.c (record_xmalloc): New function.
6638 * lisp.h (record_xmalloc): New decl.
6639 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6640 more like a function. This is because the pointer cast is not
6641 needed. All uses changed.
6642 * print.c (print_string, print_error_message): Avoid length recalc.
6644 Improve fix for macroexp crash with debugging (Bug#12118).
6645 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6646 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6647 not supposed to be invoked from the garbage collector.

6649 (gc_aset): New function, which is like ASET but can be
6650 used in the garbage collector.

6675 have the required privileges.
6676 (get_file_security_desc_by_name): Rename from

6679 with addition of handling of symlinks and support for 'lstat'.
6680 If possible, get file's attributes and security information by
6681 handle, not by name. Produce S_IFLNK bit for symlinks, when
6682 called from 'lstat'.
6683 (stat, lstat): New functions, call 'stat_worker'.
6684 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6685 symlinks when the underlying filesystem supports them.
6687 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6689 Fix macroexp crash on Windows with debugging (Bug#12118).
6690 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6691 checking subscripts; problem introduced with the recent
6692 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6693 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6694 since it's used in non-static inline functions now.
6696 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6697 Don't assume buffer size fits in 'int'. Remove unused local.

6717 * composite.c (COMPOSITE_INLINE):
6718 * dispnew.c (DISPEXTERN_INLINE):
6719 * sysdep.c (SYSTIME_INLINE):
6720 Define to EXTERN_INLINE, so that the corresponding functions
6721 are compiled into code.
6722 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6723 (INLINE_HEADER_END): New macros.
6724 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6744 hard-coding the path separator.
6746 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6748 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6749 This how ASET and AREF are supposed to work, and makes
6750 it easier to think about future improvements. See
6751 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6752 * charset.h (set_charset_attr): New function.

7240 Fix export of symbols to GDB (Bug#12036).
7241 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
7242 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7243 emacs.c, as this is a more-suitable home. Had this been done earlier
7244 the fix for 12036 would have avoided some of the problems noted in
7245 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7246 would have been more obvious.
7247 * emacs.c: Do not include <verify.h>; no longer needed.
7248 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7249 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7250 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7251 Remove; now done in lisp.h.
7252 * lisp.h (PUBLISH_TO_GDB): New macro.
7253 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
7254 (DATA_SEG_BITS): Use it.
7255 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7256 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7257 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7258 not be usable in #if. This simplifies things.
7260 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7262 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7264 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7266 Simplify export of symbols to GDB (Bug#12036).
7267 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7268 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7269 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7270 Adjust to changes in lisp.h and emacs.c, by using
7271 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7272 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7273 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7274 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7275 instead of gdb_valbits.
7276 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7277 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7278 instead of gdb_array_mark_flag.
7279 (xboolvector): Get size from $->size, not $->header.size.
7280 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7281 (xreload, hook-run, hookpost-run): Remove.
7282 * emacs.c: Include <verify.h>.
7283 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7284 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7286 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7287 (gdb_USE_LSB_TAG): New enum constants.
7288 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7289 Also define these as enum constants, so they're visible to GDB.
7290 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7291 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7292 as constants, so they're visible to GDB.
7293 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
7294 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
7295 Now enum constants, not macros, so they're visible to GDB.
7296 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7297 more convenient now. All uses changed.
7298 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7299 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7301 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
7303 Explicitly free restriction data that are not needed anymore.
7304 * editfns.c (save_restriction_restore): Free restriction data.
7306 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
7308 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7309 add argument, tune behavior, and adjust all callers.
7311 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7313 Use typedef for EMACS_INT, EMACS_UINT.
7314 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7315 than macros. This simplifies debugging in the usual case, since
7316 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7317 and it allows expressions involving EMACS_INT casts.
7318 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7320 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
7322 * nsterm.m (ns_read_socket): Return early if there is a modal

7328 that FOCUS-FRAME can be omitted.
7330 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7332 Adjust buffer text indirection counters at the end of Fkill_buffer.
7333 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7334 buffer is definitely dead. This should really fix an issue reported
7335 by Christoph Scholtes again. (Bug#12007).
7336 (init_buffer_once): Initialize indirection counters of
7337 buffer_defaults and buffer_local_symbols (for sanity and safety).
7339 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7341 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7342 and continuation glyphs on tooltip frames, leave them at zero.
7343 Avoids continued lines in tooltips. (Bug#11832)
7345 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7347 Simplify copy_overlay.
7348 * buffer.c (copy_overlay): Simplify. Use build_marker.

7354 or invalid. (Bug#12025)
7356 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
7357 it signals an error when a tooltip frame is being created.
7359 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7361 Cleanup miscellaneous objects allocation and initialization.
7362 * alloc.c (allocate_misc): Change to static. Add argument to
7363 specify the subtype. Adjust comment and users.
7364 (build_overlay): New function.
7365 * buffer.c (copy_overlays, Fmake_overlay): Use it.
7366 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.

7368 (build_overlay): Add prototype.
7370 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7372 Swap buffer text indirection counters in Fbuffer_swap_text.
7373 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7374 This avoids crash reported by Christoph Scholtes at
7375 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7377 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7379 * nsmenu.m (Popdown_data): New struct.
7380 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7382 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

7384 and autorelease them. Also autorelease img and matrix (Bug#12005).
7385 (dealloc): Remove (Bug#12005).

7398 (live_buffer, set_marker_internal): New function.
7399 (Fset_marker, set_marker_restricted): Use set_marker_internal.

7402 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7404 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7405 as it's limited by the amount of memory, not by INT_MAX.
7407 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7409 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7410 in special-event-map. See the discussion at

7491 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
7492 'for_each_per_buffer_object_at'.

7545 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
7547 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug

7560 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7562 * eval.c (Fdefvar): Don't check constants since we only set the var if
7563 it's not yet defined anyway (bug#11904).
7565 * lisp.h (last_undo_boundary): Declare new var.
7566 * keyboard.c (command_loop_1): Set it.
7567 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
7568 were auto-added by the command loop (bug#11774).
7570 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>

8138 The functional style also makes code easier to read and maintain.
8139 * systime.h: Include <sys/time.h> on all hosts, not just if
8140 WINDOWSNT, since 'struct timeval' is needed in general.
8141 (EMACS_TIME): Now a typedef, not a macro.
8142 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
8144 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
8145 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
8146 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
8147 (EMACS_TIME_LE): Now functions, not macros.
8148 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
8149 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
8150 which are not functions. All uses rewritten to use:
8151 (make_emacs_time): New function.
8152 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8153 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8154 not functions. All uses rewritten to use the following, respectively:
8155 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8156 (add_emacs_time, sub_emacs_time): New functions.
8157 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8158 * fileio.c (Fcopy_file):
8159 * xterm.c (XTflash): Get the current time closer to when it's used.
8160 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8167 * frame.c (Fmake_terminal_frame):
8168 * gtkutil.c (get_utf8_string):
8170 * nsmenu.m (ns_update_menubar):
8171 * regex.c (regerror):
8172 Prefer memcpy to strncpy and strncat when either will do.

8174 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8175 (menu_separator_name_p):
8176 * nsmenu.m (ns_update_menubar):
8177 Prefer memcmp to strncmp when either will do.
8178 * nsterm.m: Include <ftoastr.h>.
8180 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8181 Prefer snprintf to strncpy.
8182 * nsterm.m (ns_term_init):
8183 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8184 * nsterm.m (ns_term_init):
8185 Avoid the need for strncpy, by using build_string or
8186 make_unibyte_string directly. Use dtoastr, not snprintf.
8187 * process.c (Fmake_network_process): Diagnose service names that
8188 are too long, rather than silently truncating them or creating
8189 non-null-terminated names.
8190 (Fnetwork_interface_info): Likewise, for interface names.
8191 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8192 Prefer sprintf to strncat.
8193 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8194 Prefer vsnprintf to vsprintf + strncpy.
8196 2012-07-10 Glenn Morris <rgm@gnu.org>
8198 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8199 Clarify fallback case.
8201 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8203 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
8204 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
8205 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8206 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8207 where argument type is known to be a Lisp_Cons.

8219 Optimize pure C strings initialization.
8220 * lisp.h (make_pure_string): Fix prototype.
8221 (build_pure_c_string): New function, defined as static inline. This
8222 provides a better opportunity to optimize away calls to strlen when
8223 the function is called with compile-time constant argument.
8224 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8225 argument, adjust users accordingly. Use build_pure_c_string where
8227 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8228 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8229 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8231 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8233 Avoid calls to strlen in miscellaneous functions.
8234 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8235 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8236 * lread.c (openp): Likewise.
8238 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8240 Avoid calls to strlen in path processing functions.
8241 * fileio.c (file_name_as_directory): Add comment. Change to add
8242 srclen argument and return the length of result. Adjust users
8244 (directory_file_name): Fix comment. Change to add srclen argument,
8245 swap 1st and 2nd arguments to obey the common convention.
8246 Adjust users accordingly.
8247 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8249 2012-07-10 Glenn Morris <rgm@gnu.org>
8251 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
8252 Move PENDING_OUTPUT_COUNT definition to configure.
8254 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
8255 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8256 * s/gnu.h (DATA_START): Move definitions to configure.
8258 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8259 We include usg5-4-common.h, which defines them both.
8261 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8262 O_RDONLY already includes it).
8264 Stop ns builds setting the EMACSLOADPATH environment variable.
8265 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8266 Now it does not set EMACSLOADPATH, just returns the load-path string.
8267 * nsterm.h: Update accordingly.
8268 * lread.c [HAVE_NS]: Include nsterm.h.
8269 (init_lread) [HAVE_NS]: Use ns_load_path.
8270 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8272 2012-07-09 Glenn Morris <rgm@gnu.org>
8274 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8275 since the included bsd-common.h does so.
8277 Stop ns builds setting the EMACSPATH environment variable.
8278 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8279 (ns_init_paths): Do not set EMACSPATH.
8280 * nsterm.h (ns_exec_path): Add it.
8281 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8284 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8286 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8288 * process.c (wait_reading_process_output): 'waitchannels' was unset
8289 when read_kbd || !NILP (wait_for_cell); fix this.
8291 Add GCC-style 'const' attribute to functions that can use it.
8292 * character.h (char_resolve_modifier_mask):
8293 * keyboard.h (make_ctrl_char):
8294 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8295 (init_character_once, next_almost_prime, init_fns, init_image)
8296 (flush_pending_output, init_sound):
8297 * mem-limits.h (start_of_data):
8298 * menu.h (finish_menu_items):

8301 Declare the dummy function with ATTRIBUTE_CONST.
8302 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8303 Add decls with ATTRIBUTE_CONST.
8305 Minor improvements to make_formatted_string.
8306 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8307 where int is good enough, as vsprintf returns an int.
8308 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8310 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8312 Use make_formatted_string to avoid double length calculation.
8313 * lisp.h (make_formatted_string): New prototype.
8314 * alloc.c (make_formatted_string): New function.
8315 * buffer.c (Fgenerate_new_buffer_name): Use it.
8316 * dbusbind.c (syms_of_dbusbind): Likewise.
8317 * editfns.c (Fcurrent_time_zone): Likewise.
8318 * filelock.c (get_boot_time): Likewise.
8319 * frame.c (make_terminal_frame, set_term_frame_name)
8320 (x_report_frame_params): Likewise.
8321 * image.c (gs_load): Likewise.
8322 * minibuf.c (get_minibuffer): Likewise.

8337 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8339 Move marker debugging code under MARKER_DEBUG.
8340 * marker.c (MARKER_DEBUG): Move marker debugging code under
8341 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8342 for bootstrap with --enable-checking (~3x slowdown reported
8343 by Juanma Barranquero <lekktu@gmail.com>).
8344 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8346 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8348 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8349 See <http://bugs.gnu.org/11825#29>.
8351 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8353 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8354 has no font, use the frame's font. (Bug#11813)
8355 (display_line): Add commentary about displaying truncation glyphs
8357 (produce_special_glyphs): Move here from term.c.
8359 * term.c (produce_special_glyphs): Move to xdisp.c.
8361 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8364 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8366 * xdisp.c (display_line): Avoid warning about implicit declaration
8369 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8371 * lisp.h: Remove empty conditional.
8373 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8375 * lread.c (load_path_check): Now static.
8377 Fix some minor --with-ns problems found by static checking.
8378 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8379 (x_set_font) [!HAVE_X_WINDOWS]:
8380 * image.c (xpm_load_image) [HAVE_NS]:
8381 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8382 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8383 Remove unused local.
8384 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8385 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8386 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8387 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8388 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8389 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8390 Fix pointer signedness problem.
8391 * xfaces.c (FRAME_X_FONT_TABLE):
8392 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8394 2012-07-07 Glenn Morris <rgm@gnu.org>
8396 * lread.c (load_path_check): New function, split from init_lread.
8397 (init_lread): Reorganize. Motivation:
8398 If EMACSLOADPATH is set, check/warn about that rather than the
8399 defaults, which we are not going to use. Hence we can remove
8400 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8401 Don't warn if site-lisp directories are missing.
8402 If not installed, start from a blank load-path, since
8403 PATH_LOADSEARCH refers to the eventual installation directories.
8405 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8407 Support truncation and continuation glyphs on GUI frames, when
8408 fringes are disabled. (Bug#11832)
8409 * xdisp.c (init_iterator): Get dimensions of truncation and
8410 continuation glyphs even if on GUI frames.
8411 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8412 or both, are absent.
8413 (start_display, move_it_in_display_line_to): Handle the case of a
8414 GUI frame without a fringe to display continuation or truncation
8416 (insert_left_trunc_glyphs): Support GUI frames: make sure
8417 truncation glyphs overwrite enough glyphs from the current line to
8418 have sufficient space in pixels.
8419 (display_line): Support truncation and continuation glyphs on GUI
8420 frames. If some spare pixels are left on the line after inserting
8421 the truncation glyphs, fill that space with a stretch glyph of a
8422 suitably computed width.
8424 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8425 produce_glyphs, to support GUI sessions.
8427 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8429 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8431 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8433 Do not require float-time's arg to fit in time_t (Bug#11825).
8434 This works better on hosts where time_t is unsigned, and where
8435 float-time is applied to the (negative) difference between two times.
8436 * editfns.c (decode_time_components): Last arg is now double *,
8437 not int *, and means to store all the result as a double, without
8438 worrying about whether the seconds part fits in time_t.
8439 All callers changed.
8440 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8441 All callers changed.
8442 (Ffloat_time): Do not fail merely because the specified time falls
8443 outside of time_t range.
8445 2012-07-07 Glenn Morris <rgm@gnu.org>
8447 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
8448 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
8449 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
8451 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
8453 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8454 Update dependencies.
8456 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8458 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8460 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
8461 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
8462 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8463 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8464 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8465 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8467 * xfont.c (compare_font_names): Redo to omit the need for casts.
8469 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8471 * xfns.c (Fx_change_window_property): Doc fix.
8472 * w32fns.c (Fx_change_window_property): Doc fix.
8474 * w32fns.c (Fx_window_property): Accept the same arguments as the
8475 X Windows version. Doc fix.
8476 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8478 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8479 Eli Zaretskii <eliz@gnu.org>
8481 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8482 Windows-specific code from nt/config.nt moved here.
8483 Obsolete settings removed.
8485 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8487 * process.c: Avoid unnecessary calls to gettime.
8488 (wait_reading_process_output): Don't get the time of day
8489 when gobbling data immediately and not waiting, as there's no need
8490 for it in that case. This removes a FIXME.
8492 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8494 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8495 is defined (Bug#11768).
8497 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8499 Fix marker debugging code.
8500 * marker.c (byte_char_debug_check): Do not perform the check
8501 if buffer is not multibyte.
8502 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8503 Call byte_char_debug_check with correct arguments.
8505 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8507 Compile marker debugging code only if ENABLE_CHECKING is defined.
8508 * marker.c (byte_char_debug_check, count_markers):
8509 Use only if ENABLE_CHECKING is defined.
8510 (byte_debug_flag): Remove.
8511 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8512 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8514 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8516 Avoid code repetition in marker-related functions.
8517 * marker.c (attach_marker): New function.
8518 (Fset_marker, set_marker_restricted, set_marker_both)
8519 (set_marker_restricted_both): Use it.
8520 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8521 Consistently rename charno to charpos.
8522 (marker_position): Add eassert.
8523 (marker_byte_position): Convert to eassert.
8525 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8527 Simplify list operations in unchain_overlay and unchain_marker.
8528 * buffer.c (unchain_overlay): Simplify. Add comment.
8529 * marker.c (unchain_marker): Simplify. Fix comments.
8531 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8541 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8542 * window.c (save_window_save): Likewise.
8544 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8546 Do not use Fdelete_overlay in delete_all_overlays
8547 to avoid redundant calls to unchain_overlay.
8548 * buffer.c (drop_overlay): New function.
8549 (delete_all_overlays, Fdelete_overlay): Use it.
8550 * minibuf.c (get_minibuffer): Fix comment.
8552 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8554 Port to OpenBSD 5.1 amd64.
8555 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8556 This is needed for OpenBSD, and should be harmless on all BSD systems.
8557 Also, include <sys/sysctl.h>, as it should be available on all
8558 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8559 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8560 use p_pid member, not kp_proc.pid.
8562 2012-07-06 Glenn Morris <rgm@gnu.org>
8564 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8566 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8568 More xmalloc and related cleanup.
8569 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8570 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

8577 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8579 Omit needless casts involving void * pointers and allocation.
8580 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8581 as the former is more robust if P's type is changed.
8582 Prefer xzalloc to xmalloc + memset 0.
8583 Simplify malloc-or-realloc to realloc.
8584 Don't worry about xmalloc returning a null pointer.
8585 Prefer xstrdup to xmalloc + strcpy.
8586 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8588 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8589 alloca of a constant.
8591 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8593 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8594 hscroll is larger than the line width. Fixes long and futile
8595 looping inside extend_face_to_end_of_line (on a TTY) producing
8596 glyphs that are not needed and thrown away.
8598 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8600 * marker.c (set_marker_restricted_both): Simplify by using

8605 * editfns.c (region_limit): Simplify by using clip_to_bounds.
8607 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
8609 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
8610 not defined (Bug#11768).
8611 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
8612 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
8613 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
8614 followed by gtk_box_set_homogeneous (Bug#11768).
8615 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8616 (update_theme_scrollbar_width, xg_create_scroll_bar):
8617 Use gtk_scrollbar_new (Bug#11768).
8618 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

8626 * xdisp.c (window_hscroll_limited): New function.
8627 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8628 coordinates when window's hscroll is set to insanely large
8631 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8633 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8694 * fileio.c (time_error_value): Check the right error number.
8695 Problem reported by Troels Nielsen in
8696 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8698 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8700 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8701 This should be fixed in a better way; see Eli Zaretskii in
8702 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8703 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8705 * fileio.c (time_error_value): Rename from special_mtime.
8706 The old name's problems were noted by Eli Zaretskii in
8707 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8709 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8710 This variable's comment says Emacs needs at least one GDB-visible
8711 symbol of type enum pvec_type, to work around GDB problems.
8712 The symbol's value doesn't matter.
8714 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8715 that causes compilation to fail on pre-C99 compilers.
8717 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8719 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

8722 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8724 * buffer.c (init_buffer_once): Fix initialization of
8725 headers for buffer_defaults and buffer_local_symbols.
8726 Reported by Juanma Barranquero <lekktu@gmail.com>.
8728 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8730 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8731 * lisp.h (enum pvec_type): Use fewer bits.
8732 (PSEUDOVECTOR_SIZE_BITS): New constant.
8733 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8734 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8735 change in pvec_type.
8736 (PSEUDOVECTOR_TYPEP): New macro.
8737 (TYPED_PSEUDOVECTORP): Use it.
8738 * fns.c (internal_equal): Adapt code to extract pvectype.

8742 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8743 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8744 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8745 abusing vector->header.next.nbytes.
8746 (live_vector_p): Use PVEC_TYPE.
8747 (mark_object): Adapt code to extract pvectype. Use switch.
8749 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8751 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8752 Tighten new eassert a bit.
8754 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8756 Fix compilation with --enable-gcc-warnings and -O1
8758 * doprnt.c (doprnt): Change type of tem to int, initialize
8759 to avoid compiler warning. Add eassert.
8760 * search.c (simple_search): Initialize match_byte to avoid
8761 compiler warning. Add eassert.
8763 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8765 Avoid weird behavior with large horizontal scrolls.
8766 Without this change, for example, large hscroll values would
8767 mess up Emacs's display on Fedora 15 x86, presumably due to
8768 overflows in int calculations in the display code.
8769 Also, if buffers had long lines, Emacs would freeze.
8770 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8771 (set_window_hscroll): New function, containing the old guts of
8772 Fset_window_hscroll. Return the clipped value.
8773 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8774 This avoids the need to check against PTRDIFF_MAX.
8776 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8778 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8780 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8782 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8784 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8785 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8786 since GCC 4.4.6 issues a bogus warning for them.
8788 Fix bugs in file timestamp newness comparisons.
8789 * fileio.c (Ffile_newer_than_file_p):
8790 * lread.c (Fload): Use full timestamp resolution of files,
8791 not just the 1-second resolution, so that files that are only
8792 slightly newer still count as newer.
8793 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8794 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8796 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8798 * fileio.c: Improve handling of file time marker. (Bug#11852)
8799 (special_mtime): New function.
8800 (Finsert_file_contents, Fverify_visited_file_modtime):
8801 Use it to set special mtime values consistently.
8803 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8805 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8806 marker for non-existing file. (Bug#11852)
8808 2012-07-03 Glenn Morris <rgm@gnu.org>
8810 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8811 and did not make it into globals.h).
8813 2012-07-03 Tom Tromey <tromey@redhat.com>
8815 * window.c (Fset_window_margins, Fset_window_fringes)
8816 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8817 * textprop.c (Fprevious_property_change): No longer static.
8818 * syntax.c (Fsyntax_table_p): No longer static.

8840 * intervals.h: Remove EXFUNs.
8841 * fontset.h: Remove EXFUN.

8846 * w32term.h: Remove EXFUNs.
8847 * window.h: Remove EXFUNs.

8849 * xterm.h: Remove EXFUN.
8851 2012-07-03 Glenn Morris <rgm@gnu.org>
8853 * lisp.h (Frandom): Make it visible to C.
8854 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8855 buffer for invisible buffers. (Bug#1229)
8857 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8859 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8860 values which aren't power of 2.
8861 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8862 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8865 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8867 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8869 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8871 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8873 * alloc.c (allocate_vector_block): Remove redundant
8874 calls to mallopt if DOUG_LEA_MALLOC is defined.
8875 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8876 avoid calls to mallopt if zero_vector is returned.
8878 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8880 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8881 is enabled, avoid dereferencing NULL current_sblock if
8884 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8886 Cleanup basic buffer management.
8887 * buffer.h (struct buffer): Change layout to use generic vector
8888 marking code. Fix some comments. Change type of 'clip_changed'
8889 to bitfield. Remove unused #ifndef old.
8890 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8891 (GET_OVERLAYS_AT): Fix indentation.
8892 (for_each_per_buffer_object_at): New macro.
8893 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

8895 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8896 * alloc.c (allocate_buffer): Adjust to match new layout of
8897 struct buffer. Fix comment.
8898 (mark_overlay): New function.

8900 Lisp area of struct buffer.
8901 (mark_object): Use it. Adjust marking of misc objects
8902 and related comments.
8904 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8906 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8907 wrapper that is not needed because the wrapped code is a no-op (zero
8908 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8909 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8911 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8913 * alloc.c (mark_buffer): Simplify. Remove prototype.
8914 (mark_object): Add comment. Reorganize marking of vector-like
8915 objects. Use CHECK_LIVE for all vector-like objects except buffers
8916 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8917 Avoid redundant calls to mark_vectorlike for bool vectors.
8919 2012-06-30 Glenn Morris <rgm@gnu.org>
8921 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8923 * epaths.in (PATH_SITELOADSEARCH): New.
8924 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8925 This is rather than relying on --enable-locallisppath elements
8926 having "site-lisp" in their names. (Bug#10208#25, 11658)
8928 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8930 * w32proc.c (sys_select): Accept and ignore one more argument.
8932 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8934 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8935 (pselect) [!MS_DOS]: Redirect to sys_select.
8937 * sysdep.c: Don't include dos.h and dosfns.h.
8939 * process.c (sys_select):
8940 * msdos.c (sys_select): Accept one more argument and ignore it.
8942 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8943 adapt data types and code to that.
8946 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8947 which clashes with the gnulib function of the same name.
8949 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8951 * font.c (font_style_to_value, font_style_symbolic)
8952 (font_prop_validate_style): Add type checks for values in
8955 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8957 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8960 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8962 * xdisp.c (try_window_id): Undo last change.
8964 * w32.c (getwd): Adjust commentary about startup_dir.
8965 (init_environment): Always call sys_access, even in non-MSVC
8966 builds. Don't chdir to the directory of the Emacs executable.
8967 This undoes code from 1997 which was justified by the need to
8968 "avoid conflicts when removing and renaming directories". But its
8969 downside was that every relative file name was being interpreted
8970 relative to the directory of the Emacs executable, which can never
8971 be TRT. In particular, it broke sys_access when called with
8972 relative file names.
8973 (sys_access): Map GetLastError to errno.
8975 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8977 * window.h (struct window): Change type of 'fringes_outside_margins'

8981 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8984 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8986 * gnutls.c (emacs_gnutls_handshake):
8987 Add QUIT to make the loop interruptible.
8989 2012-06-29 Glenn Morris <rgm@gnu.org>
8991 * charset.c (init_charset): Make lack of etc/charsets fatal.
8993 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8995 * editfns.c (region_limit): Fix type mismatch.
8997 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8999 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9000 undefined. Convert from xassert to eassert.
9001 * nsmenu.m: Convert from xassert to eassert.
9002 * nsterm.m: Likewise.
9004 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9006 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9008 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9010 Avoid integer overflow on scroll-left and scroll-right.
9011 * window.c (HSCROLL_MAX): New macro.
9012 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9013 overflow when requested scroll falls outside ptrdiff_t range.
9015 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9017 * window.h (struct window): Change type of 'hscroll',
9018 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9019 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9020 Adjust users accordingly.
9021 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9022 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9023 from EMACS_INT to ptrdiff_t.
9024 (make_window): Omit redundant initialization.
9026 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9028 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9030 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9032 * window.h (struct window): Change type of 'use_time' and
9033 'sequence_number' from Lisp_Object to int.
9034 * frame.c (make_frame): Adjust users accordingly.
9035 * print.c (print_object): Likewise.
9036 * window.c (select_window, Fwindow_use_time, make_parent_window)
9037 (make_window): Likewise.
9039 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9041 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
9042 enabled with --enable-checking=[all,glyphs] configure option.
9043 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9044 adjust comments accordingly.
9045 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
9046 undefined, adjust comments accordingly.

9167 Use sprintf return value instead of invoking strlen on result.
9168 In the old days this wasn't portable, since some sprintf
9169 implementations returned char *. But they died out years ago and
9170 Emacs already assumes sprintf returns int.
9171 Similarly for float_to_string.
9172 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

9180 Use sprintf or float_to_string result to avoid need to call strlen.
9181 * data.c (Fnumber_to_string):
9182 Use make_unibyte_string, since the string must be ASCII.
9183 * lisp.h, print.c (float_to_string): Now returns int length.
9184 * term.c (produce_glyphless_glyph):
9185 Use sprintf result rather than recomputing it.
9187 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

9220 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

9225 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9226 instead of truncating it to 63 (admittedly a generous limit).

9287 * process.c (Faccept_process_output):

9356 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9358 Support higher-resolution time stamps (Bug#9000).
9359 The time stamps are only nanosecond-resolution at the C level,
9360 since that's the best that any real-world system supports now.
9361 But they are picosecond-resolution at the Lisp level, as that's
9362 easy, and leaves room for future OS improvements.
9364 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9367 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9368 Don't get current time unless it's needed.
9370 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9371 now provides it if it's absent.
9372 (start_atimer): Port to higher-res time stamps.
9373 Check for time stamp overflow. Don't get current time more
9374 often than is needed.
9376 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9377 Include systime.h, not time.h.
9378 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9380 * dired.c: Include stat-time.h.
9381 (Ffile-attributes): File times now have higher resolution.
9383 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9384 (struct image): Timestamp now has higher resolution.
9386 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9387 has at least microseconds now. All uses removed.
9388 (update_frame, update_single_window, update_window, update_frame_1)
9389 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9390 (duration_to_sec_usec): Remove; no longer needed.
9392 * editfns.c (time_overflow): Now extern.
9393 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9394 (float-time, Fformat_time_string, Fcurrent_time_string)

9398 (decode_time_components, lisp_seconds_argument): New functions.
9399 (make_time): Now static.
9400 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9401 Report an error if the time is invalid, rather than having the caller
9404 * fileio.c: Include <stat-time.h>
9405 (Fcopy_file): Copy higher-resolution time stamps.
9406 Prefer to set the time stamp via a file descriptor if that works.
9407 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9408 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9409 (Fvisited_file_modtime, Fset_visited_file_modtime):
9410 Support higher-resolution time stamps.
9412 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9414 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9416 * image.c (prepare_image_for_display, clear_image_cache)
9417 (lookup_image): Port to higer-resolution time stamps.
9419 * keyboard.c (start_polling, bind_polling_period):
9420 Check for time stamp overflow.
9421 (read_char, kbd_buffer_get_event, timer_start_idle)
9422 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9423 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9424 Port to higher-resolution time stamps. Do not assume time_t is signed.
9425 (decode_timer): New function. Timers are now vectors of length 9,
9426 not 8, to accommodate the picosecond component.
9427 (timer_check_2): Use it.
9429 * nsterm.m (select_timeout, timeval_subtract): Remove.
9430 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9431 as they're a bit more accurate and handle overflow better.
9432 (ns_select): Change prototype to be compatible with pselect.
9433 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9434 * nsterm.h (ns_select): Adjust prototype.
9436 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9437 us-resolution time stamps.
9438 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9440 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9442 * lisp.h (time_overflow): New decl.
9443 (wait_reading_process_output): First arg is now intmax_t, not int,
9444 to accommodate larger waits.
9446 * process.h (struct Lisp_Process.read_output_delay):
9447 Now counts nanoseconds, not microseconds.
9448 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9450 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9451 (wait_reading_process_output):
9452 Port to ns-resolution time stamps.
9453 (Faccept_process_output, wait_reading_process_output):
9454 Check for time stamp overflow. Do not assume time_t is signed.
9455 (select_wrapper): Remove; we now use pselect.
9456 (Fprocess_attributes): Now generates ns-resolution time stamps.
9458 * sysdep.c: Include utimens.h. Don't include utime.h
9459 or worry about struct utimbuf; gnulib does that for us now.
9460 (gettimeofday): Remove; gnulib provides a substitute.
9461 (make_timeval): New function.
9462 (set_file_times): Now sets ns-resolution time stamps.
9463 New arg FD; all uses changed.
9464 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9465 (system_process_attributes):
9466 Now returns ns-resolution time stamp. All uses changed.
9467 Check for time stamp overflow.
9469 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9470 provides a substitute now.
9472 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9473 since it guarantees struct timespec.
9474 (EMACS_TIME): Now struct timespec, so that we can support
9475 ns-resolution time stamps.
9476 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9477 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9478 (EMACS_USECS): Remove.
9479 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9480 so multiply the arg by 1000 before storing it.
9481 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9483 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9484 Port to ns-resolution time stamps.
9485 (EMACS_TIME_NEG_P): Remove; replaced by....
9486 (EMACS_TIME_SIGN): New macro.
9487 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9488 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9489 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9490 (make_timeval, make_lisp_time, decode_time_components): New decls.
9491 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9492 that it mishandled time_t overflow. You can't compare by subtracting!
9493 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9494 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9496 * term.c: Include <sys/time.h>.
9497 (timeval_to_Time): New function, for proper overflow wraparound.
9498 (term_mouse_position, term_mouse_click): Use it.
9500 * undo.c (record_first_change): Support higher-resolution time stamps
9502 (Fprimitive_undo): Use them when restoring time stamps.
9504 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9505 (w32_get_internal_run_time):
9506 Port to higher-resolution Emacs time stamps.
9507 (ltime): Now accepts single 64-bit integer, as that's more convenient
9510 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9512 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9513 for compatibility with pselect. Support ns-resolution time stamps.
9515 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9517 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9518 Check for time stamp overflow, and support ns-resolution time stamps.
9520 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9521 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9522 (timeval_subtract): Remove; no longer needed.
9523 (XTflash, XTring_bell, x_wait_for_event):
9524 Port to ns-resolution time stamps. Don't assume time_t is signed.
9526 2012-06-22 Chong Yidong <cyd@gnu.org>
9528 * xdisp.c (x_consider_frame_title): Revert last change.
9530 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9532 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9533 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER

9809 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9810 Use an inline function on all platforms when using the union type,
9811 since this is simpler and 'static inline' can be used portably

9956 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9957 would mishandle a string argument "Xc" if X was a multibyte

9959 rather than including all of X.

10012 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10013 Convert pctcpu and pctmem to Lisp float properly.
10014 Let the compiler fold better, as 100.0/0x8000 is exact.
10016 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10018 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10021 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
10023 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
10025 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10027 For a 'struct window', replace some Lisp_Object fields to
10028 bitfields where appropriate, remove unused fields.
10029 * window.h (struct window): Remove unused 'last_mark_x' and
10030 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10031 change its type from Lisp_Object to bitfield.
10032 Change type of 'force_start', 'optional_new_start',
10033 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10034 fields from Lisp_Object to bitfield. Adjust users accordingly.
10036 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10038 Pacify gcc -Wdouble-precision when using Xaw.
10039 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10040 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10041 Use 'float' consistently, rather than 'float' in most places
10042 and 'double' in a couple of places.
10044 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10046 * xdisp.c (handle_stop): Detect whether we have overlay strings
10047 loaded by testing it->current.overlay_string_index to be
10048 non-negative, instead of checking whether n_overlay_strings is
10049 positive. (Bug#11587)
10051 2012-05-31 Chong Yidong <cyd@gnu.org>
10053 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10055 * doc.c (Fsubstitute_command_keys): Doc fix.
10057 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10059 * search.c (search_buffer): Remove calls to
10060 r_alloc_inhibit_buffer_relocation, as it is now called by
10061 maybe_unify_char, which was the cause of relocation of buffer text
10064 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10066 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10067 for the duration of call to load_charset, to avoid problems with
10068 callers of maybe_unify_char that access buffer text through C
10071 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10072 decrement the inhibition flag, instead of just setting or
10075 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10077 Remove obsolete '#define static' cruft.
10078 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10079 This #undef was "temporary" in 2000; it is no longer needed
10080 now that '#define static' has gone away.
10081 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10082 (gray_bitmap_bits): Remove; no longer needed.
10083 All uses replaced with definiens.
10084 * xterm.c: Include "bitmaps/gray.xbm".
10086 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10088 Clean up __executable_start, monstartup when --enable-profiling.
10089 The following changes affect the code only when profiling.
10090 * dispnew.c (__executable_start): Rename from safe_bcopy.
10091 Define only on platforms that need it.
10092 * emacs.c: Include <sys/gmon.h> when profiling.
10093 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10094 (__executable_start): Remove decl, since lisp.h does it now.
10095 (safe_bcopy): Remove decl; no longer has that name.
10096 (main): Coalesce #if into single bit of code, for simplicity.
10097 Cast pointers to uintptr_t, since standard libraries want integers
10099 * lisp.h (__executable_start): New decl.
10101 2012-05-31 Glenn Morris <rgm@gnu.org>
10103 * image.c (Fimagemagick_types): Doc fix.
10105 2012-05-30 Jim Meyering <meyering@redhat.com>
10107 * callproc.c (Fcall_process_region): Include directory component
10108 in mkstemp error message (Bug#11586).
10110 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10112 * alloc.c, lisp.h (make_pure_vector): Now static.
10114 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10116 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10117 Move to byte-run.el.
10118 (Fautoload): Do the hash-doc more carefully.
10119 * data.c (Fdefalias): Purify definition, except for keymaps.
10120 (Qdefun): Move from eval.c.
10121 * lisp.h (Qdefun): Remove.
10122 * lread.c (read1): Tiny simplification.
10124 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10126 Do not create empty overlays with the evaporate property (Bug#9642).
10127 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10128 Bug#9642, but explicitly check that the buffer the overlay would
10129 be moved to is live and rearrange lines to make sure that errors
10130 will not put the overlay in an inconsistent state.
10131 (Fdelete_overlay): Cosmetics.
10133 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10135 * w32term.c (my_bring_window_to_top): New function.
10136 (x_raise_frame): Use handle returned by DeferWindowPos, which
10137 could be different from the original one.
10138 Call my_bring_window_to_top instead of my_set_foreground_window.
10141 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
10142 by calling BringWindowToTop.
10144 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

10147 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10149 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10150 This avoids undefined behavior that might cause the eassert
10151 to not catch an out-of-range value.
10153 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10155 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10156 Update dependencies.
10158 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10160 * bidi.c (bidi_mirror_char): Fix last change.
10162 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
10164 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
10165 when referring to sectname field in printf format.
10167 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10169 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10170 Only r_alloc_inhibit_buffer_relocation needed to be added;
10171 the others were already declared.
10173 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10174 before checking whether it's out of range. Put the check inside
10176 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10178 2012-05-27 Ken Brown <kbrown@cornell.edu>
10180 * callproc.c (Fcall_process): Restore a line that was accidentally
10181 commented out in the 2011-02-13 change (bug#11547).
10183 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10185 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10186 defined on ralloc.c.
10188 * buffer.c [REL_ALLOC]: Remove prototypes of
10189 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10190 they are now on lisp.h.
10192 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10194 * search.c (search_buffer): Use it to inhibit relocation of buffer
10195 text while re_search_2 is doing its job, because re_search_2 is
10196 passed C pointers to buffer text. (Bug#11519)
10198 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10199 Update value to 24.
10201 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10202 state after an additional call to move_it_in_display_line_to, keep
10203 the values of it->max_ascent and it->max_descent found for the
10205 (pos_visible_p): Revert the comparison against bottom_y to what it
10206 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10209 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10211 Fix coding-related core dumps with gcc -ftrapv.
10212 The code was computing A - B, where A and B are pointers, and B is
10213 random garbage. This can lead to core dumps on platforms that
10214 have special pointer registers, and it also leads to core dumps on
10215 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10216 A - B only when B is initialized properly.
10217 * coding.c (coding_set_source, coding_set_destination): Return void.
10218 (coding_change_source, coding_change_destinations): New functions,
10219 with the old behaviors of coding_set_source and coding_set_destination.
10220 All callers that need an offset changed to use these new functions.
10222 2012-05-26 Glenn Morris <rgm@gnu.org>
10224 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10226 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10228 Extend mouse support on W32 text-mode console.
10229 * xdisp.c (draw_row_with_mouse_face):
10230 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10232 * w32console.c: Include window.h.
10233 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10235 (initialize_w32_display): Initialize mouse-highlight data.
10237 * w32inevt.c: Include termchar.h and window.h.
10238 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10239 moves, call note_mouse_highlight. If help_echo changed, call
10240 gen_help_event to produce help-echo message in the echo area.
10241 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10244 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10246 * lread.c (read1): Simplify slightly to avoid an overflow warning
10247 with GCC 4.7.0 on x86-64.
10249 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10251 * bidi.c (bidi_mirror_char): Revert last change: an int is
10252 definitely wide enough here.
10254 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10256 Fix integer width and related bugs (Bug#9874).
10257 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
10258 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
10259 (string_bytes, check_sblock, allocate_string_data):
10260 (compact_small_strings, Fmake_bool_vector, make_string)
10261 (make_unibyte_string, make_multibyte_string)
10262 (make_string_from_bytes, make_specified_string)
10263 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10264 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10266 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10267 (allocate_pseudovector):
10268 Use int, not EMACS_INT, where int is wide enough.
10269 (inhibit_garbage_collection, Fgarbage_collect):
10270 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10271 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10272 int might not be wide enough.
10273 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10274 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10275 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10276 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10277 (bidi_level_of_next_char, bidi_move_to_visually_next):
10278 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10279 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10280 (Fkill_buffer, Fset_buffer_major_mode)
10281 (advance_to_char_boundary, Fbuffer_swap_text)
10282 (Fset_buffer_multibyte, overlays_at, overlays_in)
10283 (overlay_touches_p, struct sortvec, record_overlay_string)
10284 (overlay_strings, recenter_overlay_lists)
10285 (adjust_overlays_for_insert, adjust_overlays_for_delete)
10286 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
10287 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
10288 (Foverlay_recenter, last_overlay_modification_hooks_used)
10289 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10290 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10291 (validate_region): Omit unnecessary test for b <= e,
10292 since that's guaranteed by the previous test.
10293 (adjust_overlays_for_delete): Avoid pos + length overflow.
10294 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10295 (report_overlay_modification):
10296 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10297 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10298 Omit pointer cast, which isn't needed anyway, and doesn't work
10299 after the EMACS_INT -> ptrdiff_t change.
10300 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10301 * buffer.h: Adjust decls to match defn changes elsewhere.
10302 (struct buffer_text, struct buffer):
10303 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10304 Use EMACS_INT, not int, where int might not be wide enough.
10305 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10306 not int, to avoid needless 32-bit limit on 64-bit hosts.
10307 (exec_byte_code): Use tighter memory-full test, one that checks
10308 for alloca overflow. Don't compute the address of the object just
10309 before an array, as that's not portable. Use EMACS_INT, not
10310 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10311 * callint.c (Fcall_interactively):
10312 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10313 * callproc.c (call_process_kill, Fcall_process):
10314 Don't assume pid_t fits into an Emacs fixnum.
10315 (call_process_cleanup, Fcall_process, child_setup):
10316 Don't assume pid_t fits into int.
10317 (call_process_cleanup, Fcall_process, delete_temp_file)
10318 (Fcall_process_region):
10319 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10320 (Fcall_process): Simplify handling of volatile integers.
10321 Use int, not EMACS_INT, where int will do.
10322 * casefiddle.c (casify_object, casify_region, operate_on_word)
10323 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10324 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10325 (casify_object): Avoid integer overflow when overallocating buffer.
10326 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10327 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10328 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10329 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10330 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10331 integers are now checked earlier. All uses replaced with XINT.
10333 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10334 For CCL_MapSingle, check that content and value are in int range.
10335 (ccl_driver, Fregister_code_conversion_map):
10336 Check that Vcode_version_map_vector is a vector.
10337 (resolve_symbol_ccl_program): Check that vector header is in range.
10338 Always copy the vector, so that we can check its contents reliably
10339 now rather than having to recheck each instruction as it's being
10340 executed. Check that vector words fit in 'int'.
10341 (ccl_get_compiled_code, Fregister_ccl_program)
10342 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10343 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10344 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10345 contents are in range.
10346 (Fccl_execute_on_string): Check that status is in range.
10347 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10348 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10349 Accept and return EMACS_INT, not int, because callers can pass values
10350 out of 'int' range.
10351 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10352 (multibyte_chars_in_text, parse_str_as_multibyte)
10353 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
10354 (str_as_unibyte, str_to_unibyte, string_count_byte8)
10355 (string_escape_byte8, Fget_byte):
10356 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10357 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10358 avoid mishandling large integers.
10359 * character.h: Adjust decls to match defn changes elsewhere.
10360 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10361 (Ffind_charset_region):
10362 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10363 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
10364 (load_charset_map_from_vector, Fdefine_charset_internal):
10365 Don't assume fixnum fits in int.
10366 (load_charset_map_from_vector, Fmap_charset_chars):
10367 Remove now-unnecessary CHECK_NATNUMs.
10368 (Fdefine_charset_internal): Check ranges here, more carefully.
10369 Don't rely on undefined behavior with signed left shift overflow.
10370 Don't assume unsigned int fits into fixnum, or that fixnum fits
10371 into unsigned int. Don't require max_code to be a valid fixnum;
10372 that's not true for gb10830 4-byte on a 32-bit host. Allow
10373 invalid_code to be a cons, for the same reason. Require code_offset
10374 to be a character. Avoid int overflow if max_char is close
10376 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10377 this is intended anyway and avoids some undefined behavior.
10378 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10379 INDEX_TO_CODE_POINT, as that's what it expects.
10380 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10381 * charset.h (DECODE_CHAR): Return int, not unsigned;
10382 this is what was intended anyway, and it avoids undefined behavior.
10383 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10384 integer-overflow issues.
10385 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10386 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10387 where the argument is EMACS_INT, and this behavior is not intended.
10388 * chartab.c (Fmake_char_table, Fset_char_table_range)
10389 (uniprop_get_decoder, uniprop_get_encoder):
10390 Don't assume fixnum fits in int.
10391 * cmds.c (move_point): New function, that does the gist of
10392 Fforward_char and Fbackward_char, but does so while checking
10393 for integer overflow more accurately.
10394 (Fforward_char, Fbackward_char): Use it.
10395 (Fforward_line, Fend_of_line, internal_self_insert)
10396 (internal_self_insert):
10397 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10398 Fix a FIXME, by checking for integer overflow when calculating
10399 target_clm and actual_clm.
10400 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
10401 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)

11092 Use VAL_MAX, not VALBITS, in #if.
11093 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11094 (EMACS_UINT): Define unconditionally now.
11095 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11096 (BITS_PER_EMACS_INT): New constants, replacing
11097 what used to be in config.h, but not useful in #if.
11098 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11099 define them any more.
11100 (VAL_MAX): New macro.
11102 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11103 BITS_PER_EMACS_INT, in #if.
11104 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11105 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11106 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11107 * s/ms-w32.h (DATA_START):
11108 Move here from removed file m/intel386.h.
11109 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11110 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11112 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11114 Assume C89 or later.
11115 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11116 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11118 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
11119 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
11120 * textprop.c, tparam.c (NULL): Remove.
11121 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
11122 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
11123 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
11124 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11125 * xterm.c (input_signal_count): Assume volatile works.
11127 2012-05-21 Ken Brown <kbrown@cornell.edu>
11129 * xgselect.c (xg_select): Fix first argument in call to 'select'
11132 2012-05-20 Ken Brown <kbrown@cornell.edu>
11134 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11135 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11137 2012-05-19 Ken Brown <kbrown@cornell.edu>
11139 * xfns.c (x_in_use): Remove `static' qualifier.
11140 * xterm.h (x_in_use): Declare.
11141 * xgselect.c: Include xterm.h.
11142 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11143 and `display_arg' (bug#9754).
11145 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11147 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11149 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11150 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11152 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11154 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11156 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11157 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11159 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11160 reference to image_cache->refcount.
11161 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11163 2012-05-17 Juri Linkov <juri@jurta.org>
11165 * search.c (Fword_search_regexp, Fword_search_backward)
11166 (Fword_search_forward, Fword_search_backward_lax)
11167 (Fword_search_forward_lax): Move functions to isearch.el
11168 (bug#10145, bug#11381).
11170 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11172 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11174 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11176 * lread.c (init_obarray): Declare Qt and Qnil as special.
11178 2012-05-14 Glenn Morris <rgm@gnu.org>
11180 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11181 Put "libexec" before "bin", for the sake of init_callproc_1.
11183 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11185 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11187 * unexaix.c: Port to more-recent AIX compilers.
11188 (report_error, report_error_1, make_hdr, copy_sym)
11189 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11190 Make arguments const char *, not char *, to avoid violations of C
11191 standard and to fix some AIX warnings reported by Gilles Pion.
11193 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11195 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11196 already have overlays loaded.
11197 (handle_single_display_spec): Before returning without displaying
11198 fringe bitmap, synchronize the bidi iterator with the main display
11199 iterator, by calling iterate_out_of_display_property.
11200 (iterate_out_of_display_property): Detect buffer iteration by
11201 testing that it->string is a Lisp string.
11202 (get_next_display_element): When the current object is exhausted,
11203 and there's something on it->stack, call set_iterator_to_next to
11204 proceed with what's on the stack, instead of returning zero.
11205 (set_iterator_to_next): If called at the end of a Lisp string,
11206 proceed to consider_string_end without incrementing string
11207 position. Don't increment display vector index past the end of
11208 the display vector. (Bug#11417)
11209 (pos_visible_p): Don't report a position visible when move_it_to
11210 stopped at the last line of window, which happens to be scanned
11211 backwards by the bidi iteration. (Bug#11464)
11213 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11215 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11216 and right-margin display specs even if the spec is invalid or we
11217 are on a TTY, and thus unable to display on the fringes.
11218 That's because the text with the property will not be displayed anyway,
11219 so we need to signal to the caller that this is a "replacing"
11220 display spec. This fixes display when the spec is invalid or we
11223 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11225 * unexaix.c (make_hdr): Fix typo in prototype.
11226 This bug broke the build on AIX. Problem reported by Gilles Pion.
11228 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11230 * keyboard.c (kbd_buffer_get_event): Read special events also in
11231 batch mode. (Bug#11415)
11233 2012-05-12 Glenn Morris <rgm@gnu.org>
11235 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11237 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11239 * lisp.mk (lisp): Add newcomment.elc.
11241 2012-05-12 Glenn Morris <rgm@gnu.org>
11243 * Makefile.in (MKDIR_P): New, set by configure.
11244 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11246 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11248 Remove unused function hourglass_started.
11249 * dispextern.h (hourglass_started):
11250 * w32fns.c (hourglass_started):
11251 * xdisp.c (hourglass_started): Remove.
11253 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11255 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11256 Update dependencies.
11258 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11260 * xgselect.c (xg_select): Put maxfds+1 into a var.
11261 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11263 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11265 2012-05-10 Dave Abrahams <dave@boostpro.com>
11267 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11268 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11270 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11272 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11273 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11274 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11275 Initialize xd_registered_buses.
11277 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11279 Untag more efficiently if USE_LSB_TAG.
11280 This is based on a proposal by YAMAMOTO Mitsuharu in
11281 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11282 For an admittedly artificial (nth 8000 longlist) benchmark on
11283 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11284 Emacs's overall text size by 1%.
11285 * lisp.h (XUNTAG): New macro.
11286 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11287 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11288 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11289 * eval.c (Fautoload):
11290 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11291 * frame.h (XFRAME): Use XUNTAG.
11293 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11294 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11295 Remove unportable assumptions about print widths of types like
11297 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11298 intptr_t when converting between pointer and integer, to avoid GCC
11299 warnings about wrong width.
11301 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11303 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11304 stack for each reader_thread, instead of defaulting to 8MB
11305 determined by the linker. This avoids failures in creating
11306 subprocesses on Windows 7, see the discussion in this thread:
11307 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11309 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11311 Fix up display of the *Minibuf-0* buffer in the mini window.
11312 * keyboard.c (read_char): Don't clear the echo area if there's no
11314 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11315 contents of *Minibuf-0*) if there's no message displayed in its stead.
11317 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11319 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11322 2012-05-06 Chong Yidong <cyd@gnu.org>
11324 * lisp.mk (lisp): Update.
11326 2012-05-05 Jim Meyering <meyering@redhat.com>
11328 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11330 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11332 * data.c (PUT_ERROR): New macro.
11333 (syms_of_data): Use it. Add new error type `user-error'.
11334 * undo.c (user_error): New function.
11335 (Fprimitive_undo): Use it.
11336 * print.c (print_error_message): Adjust print style for `user-error'.
11337 * keyboard.c (user_error): New function.
11338 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11340 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11342 Do not limit current-time-string to years 1000..9999.
11343 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11344 (Fcurrent_time_string): Support any year that is supported by the
11345 underlying localtime representation. Don't use asctime, as it
11346 has undefined behavior for years outside the range -999..9999.
11348 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11350 Fix race conditions involving setenv, gmtime, localtime, asctime.
11351 Without this fix, interrupts could mess up code that uses these
11352 nonreentrant functions, since setting TZ invalidates existing
11353 tm_zone or tzname values, and since most of these functions return
11354 pointers to static storage.
11355 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11356 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11357 Grow the critical sections to include not just invoking
11358 localtime/gmtime, but also accessing these functions' results
11359 including their tm_zone values if any, and any related TZ setting.
11360 (format_time_string): Last arg is now struct tm *, not struct tm **,
11361 so that the struct tm is saved in the critical section.
11362 All callers changed. Simplify allocation of initial buffer, partly
11363 motivated by the fact that memory allocation needs to be outside
11364 the critical section.
11366 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11368 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11369 with RESET_INTERVAL.
11371 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11372 Remove duplicated buffer name initialization.
11374 2012-05-02 Jim Meyering <jim@meyering.net>
11376 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11378 * xfns.c (x_window): Use xstrdup (Bug#11375).
11380 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11382 * xdisp.c (pos_visible_p): If already at a newline from the
11383 display string before the 'while' loop, don't walk back the glyphs
11384 from it3.glyph_row. Solves assertion violation when the display
11385 string begins with a newline (egg.el). (Bug#11367)
11387 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11389 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11392 2012-05-01 Glenn Morris <rgm@gnu.org>
11394 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11395 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11396 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11397 All were removed before 23.1.
11399 * dispnew.c: Remove HAVE_LIBNCURSES test;
11400 it is always true on relevant platforms.
11402 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11403 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11405 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11407 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11409 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11410 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11413 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11415 Do not avoid creating empty evaporating overlays (Bug#9642).
11416 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11417 That is, do not delete an evaporating overlay if it becomes
11418 empty after its bounds are adjusted to fit within its buffer.
11419 This fix caused other problems, and I'm reverting it until we get
11420 to the bottom of them.
11422 2012-04-27 Chong Yidong <cyd@gnu.org>
11424 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11426 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11428 * xdisp.c (pos_visible_p): If the window start position is beyond
11429 ZV, start the display from buffer beginning. Prevents assertion
11430 violation in init_iterator when the minibuffer window is scrolled
11431 via the scroll bar.
11433 * window.c (window_scroll_pixel_based): Likewise.
11435 2012-04-27 Chong Yidong <cyd@gnu.org>
11437 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11439 2012-04-27 Glenn Morris <rgm@gnu.org>
11441 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11442 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11444 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11446 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11447 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11449 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11451 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11452 display element, check also the underlying string or buffer
11453 character. (Bug#11341)
11455 * w32menu.c: Include w32heap.h.
11456 (add_menu_item): If the call to AppendMenuW (via
11457 unicode_append_menu) fails, disable Unicode menus only if we are
11458 running on Windows 9X/Me.
11460 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11462 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11463 (xgetint): Add missing shift for LSB tags.
11465 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11467 * keyboard.c (read_char): Don't wipe echo area for select window
11468 events: These might get delayed via `mouse-autoselect-window'
11471 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11473 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11474 manipulation of :loaded-from data.
11476 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11478 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11479 now a cons (bug#11311).
11481 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11483 Do not create empty overlays with the evaporate property (Bug#9642).
11484 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11485 if it becomes empty after its bounds are adjusted to fit within
11486 its buffer. Without this fix, in a nonempty buffer (let ((o
11487 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11488 yields an empty overlay that has the evaporate property, which is
11489 not supposed to happen.
11491 Fix minor GTK3 problems found by static checking.
11492 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11493 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11494 (struct _EmacsFixedClass, emacs_fixed_get_type):
11495 Move decls here from emacsgtkfixed.h, since they needn't be public.
11496 (emacs_fixed_get_type): Now static.
11497 (emacs_fixed_class_init): Omit unused local.
11498 (emacs_fixed_child_type): Remove; unused.
11499 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11500 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11501 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11502 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11503 (EMACS_FIXED_GET_CLASS): Remove; unused.
11504 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11506 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11507 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11509 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11511 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11512 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11513 (__malloc_size_t, __malloc_ptrdiff_t):
11514 Remove. All uses removed, replaced by the definiens if needed,
11515 since we can assume C89 or better now.
11516 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
11517 (protect_malloc_state, align, get_contiguous_space)
11518 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
11519 (malloc_atfork_handler_child, malloc_enable_thread)
11520 (malloc_initialize_1, __malloc_initialize, morecore_nolock)
11521 (_malloc_internal_nolock, _malloc_internal, malloc, _malloc)
11522 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
11523 (special_realloc, _realloc_internal_nolock, _realloc_internal)
11524 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11525 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11526 Define using prototypes, not old style.

11604 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11606 * sysdep.c [__FreeBSD__]: Minor cleanups.
11607 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11608 Use Emacs indenting style more consistently. Avoid some casts.

11692 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11693 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11694 (NEED_MEM_INSERT): New macro.
11695 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11696 Remove one incorrect comment and fix another.

11732 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11733 * s/netbsd.h, s/sol2-6.h:
11734 Remove definition of GC_MARK_STACK, since the default now works.
11735 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

11763 2012-04-11 Daniel Colascione <dancol@dancol.org>
11765 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11766 against is gone. It's better to use vfork now so that when Cygwin
11767 gains a new, working vfork, we use it automatically (bug#10398).
11769 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11822 * minibuf.c (Fread_variable): Callers changed.
11824 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11826 * xdisp.c (set_cursor_from_row): If the display string appears in
11827 the buffer at position that is closer to point than the position
11828 after the display string, display the cursor on the first glyph of
11829 the display string. Fixes cursor display when a 'display' text
11830 property immediately follows invisible text. (Bug#11094)
11832 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11834 composite.c: use 'double' consistently
11835 * composite.c (get_composition_id): Use 'double' consistently
11836 instead of converting 'float' to 'double' and vice versa; this is
11837 easier to understand and avoids a GCC warning.
11839 2012-04-09 Glenn Morris <rgm@gnu.org>
11841 * Makefile.in: Generate leim-list with bootstrap-emacs, in

11886 [!WINDOWSNT]: New macros.
11887 (init_libxml2_functions, libxml2_loaded_p): New functions.

11891 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11893 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

11903 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11905 * indent.c (Fvertical_motion): If there is a display string at
11906 point, use it.vpos to compute how many lines to backtrack after
11907 move_it_to point. (Bug#11133)
11909 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11911 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11912 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11913 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11914 macros related to unification of CJK characters. For the details,
11915 see the discussion following the message here:
11916 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

11932 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11934 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11935 position we get to after a call to move_it_to fails the
11936 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11937 only if we wind up in a string from display property. (Bug#11063)
11939 * window.c (Fdelete_other_windows_internal): Invalidate the row
11940 and column information about mouse highlight, so that redisplay
11941 restores it after reallocating the glyph matrices. (Bug#7464)
11943 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11944 string comes from a `display' text property, use the buffer
11945 position of that property as if we actually saw that position in
11947 (move_it_by_lines): Remove the assertion that
11948 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11949 violated when there's a before-string at the beginning of a line.

11971 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11974 2012-03-26 Kenichi Handa <handa@m17n.org>
11976 * dispextern.h (struct glyph): Fix previous change. Change the
11977 bit length of glyphless.ch to 25 (Bug#11082).
11979 2012-03-26 Chong Yidong <cyd@gnu.org>
11981 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11982 (command_loop_1): Use it; inhibit selection update for
11983 handle-select-window too (Bug#8996).
11985 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
11987 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11989 2012-03-25 Kenichi Handa <handa@m17n.org>
11991 * dispextern.h (struct glyph): Change the bit length of
11992 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11994 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11996 * s/ms-w32.h (tzname): Include time.h before redirecting to
11997 _tzname. Fixes the MSVC build. (Bug#9960)
11999 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12001 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12004 * xterm.c (XTread_socket): Only modify handling_signal if
12005 !SYNC_INPUT. (Bug#11080)
12007 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12009 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12010 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12011 when fetching a multibyte character consumes more bytes than
12012 CHAR_BYTES returns, due to unification of CJK characters in
12013 string_char. (Bug#11073)
12015 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12017 * process.c (wait_reading_process_output): Handle pty disconnect
12018 by refraining from sending oneself a SIGCHLD (bug#10933).
12020 2012-03-22 Chong Yidong <cyd@gnu.org>

12024 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12025 Mark string as coming from a prefix property.
12026 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12027 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12029 2012-03-21 Chong Yidong <cyd@gnu.org>
12031 * xfaces.c (Vface_remapping_alist): Doc fix.
12033 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12035 * w32proc.c (Fw32_set_console_codepage)
12036 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12039 2012-03-20 Chong Yidong <cyd@gnu.org>
12041 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12042 to reflect default non-nil value of redisplay-dont-pause.
12044 2012-03-19 Kenichi Handa <handa@m17n.org>
12046 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12047 it fit in a valid range (Bug#11003).
12049 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12051 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12052 that is not from display property, accept the row as a "cursor
12053 row" if one of the string's character has a non-nil `cursor'
12054 property. Fixes cursor positioning when there are newlines in
12055 overlay strings, e.g. in icomplete.el. (Bug#11035)
12057 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12059 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12061 2012-03-12 Chong Yidong <cyd@gnu.org>
12063 * eval.c (inhibit_lisp_code): Rename from
12064 inhibit_window_configuration_change_hook; move from window.c.
12066 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12067 * window.c (run_window_configuration_change_hook)
12068 (syms_of_window): Callers changed.
12070 2012-03-11 Chong Yidong <cyd@gnu.org>
12072 * keymap.c (Fkey_description): Doc fix (Bug#9700).
12074 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12076 2012-03-10 Chong Yidong <cyd@gnu.org>
12078 * frame.c (other_visible_frames): Don't assume the selected frame
12079 is visible (Bug#10955).
12081 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12083 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

12087 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12088 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12091 2012-03-03 Glenn Morris <rgm@gnu.org>
12093 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12095 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12097 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12098 position past the first glyph_row that ends at ZV. (Bug#10902)
12099 (redisplay_window, next_element_from_string): Fix typos in
12101 (redisplay_window): Pass to move_it_vertically the margin in
12102 pixels, not in screen lines.
12104 2012-03-02 Glenn Morris <rgm@gnu.org>
12106 * buffer.c (buffer-list-update-hook): Doc fix.
12108 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12110 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12111 push_it before setting up the iterator for the first overlay
12112 string, even if we have an empty string loaded.
12113 (next_overlay_string): If there's an empty string on the iterator
12114 stack, pop the stack. (Bug#10903)
12116 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12118 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12119 Suggested by Stefan Monnier in
12120 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12121 * alloc.c (widen_to_Lisp_Object): New static function.
12122 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12123 and widening them to Lisp_Objects. This would work even if
12124 USE_LSB_TAG is defined and wide integers are used, which might
12125 happen in a future version of Emacs.
12127 2012-02-25 Chong Yidong <cyd@gnu.org>
12129 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12132 * xselect.c (Fx_selection_exists_p): Doc fix.
12133 (x_clipboard_manager_save_all): Print an informative message
12134 before saving to clipboard manager.
12136 2012-02-24 Chong Yidong <cyd@gnu.org>
12138 * keyboard.c (process_special_events): Handle all X selection
12139 requests in kbd_buffer, not just the next one (Bug#8869).
12141 2012-02-23 Chong Yidong <cyd@gnu.org>
12143 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12144 call when setting menu-bar-lines and tool-bar-lines parameters.
12145 (unwind_create_frame_1): New helper function.
12147 * window.c (inhibit_window_configuration_change_hook): New var.
12148 (run_window_configuration_change_hook): Obey it.
12149 (syms_of_window): Initialize it.
12151 2012-02-22 Chong Yidong <cyd@gnu.org>
12153 * xterm.c (x_draw_image_relief): Add missing type check for
12154 Vtool_bar_button_margin (Bug#10743).
12156 2012-02-21 Chong Yidong <cyd@gnu.org>
12158 * fileio.c (Vfile_name_handler_alist): Doc fix.
12160 * buffer.c (Fget_file_buffer): Protect against invalid file
12161 handler return value.
12163 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
12165 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
12166 when computing $valmask.
12168 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12169 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12170 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12171 It's useless in that case, and it can cause problems on hosts
12172 that allocate halves of EMACS_INT values separately.
12173 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12174 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12175 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12176 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12177 it avoids undefined behavior on hosts where shifting right by more
12178 than the word width has undefined behavior.
12180 2012-02-19 Chong Yidong <cyd@gnu.org>
12182 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12183 (Funhandled_file_name_directory, Ffile_name_as_directory)
12184 (Fdirectory_file_name, Fexpand_file_name)
12185 (Fsubstitute_in_file_name): Protect against invalid file handler
12186 return values (Bug#10845).
12188 2012-02-18 Eli Zaretskii <eliz@gnu.org>
12190 * .gdbinit (pitx): Fix incorrect references to fields of the
12193 2012-02-17 Chong Yidong <cyd@gnu.org>

12200 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12202 2012-02-15 Chong Yidong <cyd@gnu.org>
12204 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12205 marked as special. Also, starting docstrings with * is obsolete.

12218 * keymap.c (Fsingle_key_description): Handle char ranges.
12220 2012-02-12 Chong Yidong <cyd@gnu.org>
12222 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12223 as that creates a dangerous corner case.
12225 * window.c (Fdelete_window_internal): Invalidate the mouse
12226 highlight (Bug#9904).
12228 2012-02-12 Glenn Morris <rgm@gnu.org>

12231 (Fx_get_selection_internal, Fx_disown_selection_internal)
12232 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12233 * nsselect.m (Fx_own_selection_internal)
12234 (Fx_disown_selection_internal, Fx_selection_exists_p)
12235 (Fx_selection_owner_p, Fx_get_selection_internal):
12236 Sync docs and argument specs with the xselect.c versions.
12238 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12240 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
12242 2012-02-11 Eli Zaretskii <eliz@gnu.org>
12244 * w32select.c (Fx_selection_exists_p): Sync doc string and
12245 argument list with xselect.c. (Bug#10783)
12247 * w16select.c (Fx_selection_exists_p): Sync doc string and
12248 argument list with xselect.c. (Bug#10783)

12258 2012-02-07 Chong Yidong <cyd@gnu.org>
12260 * buffer.c (Fbuffer_local_variables)
12261 (buffer_lisp_local_variables): Handle unbound vars correctly;
12262 don't let Qunbound leak into Lisp.
12264 2012-02-07 Glenn Morris <rgm@gnu.org>
12266 * image.c (Fimagemagick_types): Doc fix.
12268 * image.c (imagemagick-render-type): Change it from a lisp object
12269 to an integer. Move the doc here from the lisp manual.
12270 Treat all values not equal to 0 the same.
12272 2012-02-06 Chong Yidong <cyd@gnu.org>
12274 * doc.c (store_function_docstring): Avoid applying docstring of
12275 alias to base function (Bug#2603).
12277 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
12279 * .gdbinit (pp1, pv1): Remove redundant defines.
12282 2012-02-04 Chong Yidong <cyd@gnu.org>
12284 * nsterm.m: Declare a global (Bug#10694).
12286 2012-02-04 Eli Zaretskii <eliz@gnu.org>
12288 * w32.c (get_emacs_configuration_options):
12289 Include --enable-checking, if specified, in the return value.
12291 2012-02-04 Martin Rudalics <rudalics@gmx.at>
12293 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
12294 after rounding frame sizes. (Bug#9723)

12298 * keyboard.c (adjust_point_for_property): Don't position point
12299 before BEGV. (Bug#10696)
12301 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12303 Handle overflow when computing char display width (Bug#9496).
12304 * character.c (char_width): Return EMACS_INT, not int.
12305 (char_width, c_string_width): Check for overflow when
12306 computing the width; this is possible now that individual
12307 characters can have unbounded width. Problem introduced
12308 by merge from Emacs 23 on 2012-01-19.
12310 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
12312 * dbusbind.c (Fdbus_register_method): Mention the return value
12313 :ignore in the docstring.
12315 2012-02-02 Glenn Morris <rgm@gnu.org>
12317 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.

12325 2012-02-02 Kenichi Handa <handa@m17n.org>
12327 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
12328 0, do not call append_composite_glyph.
12330 2012-02-02 Kenichi Handa <handa@m17n.org>
12332 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12334 (x_produce_glyphs): If the component of a composition is a null
12335 string, set it->pixel_width to 1 to avoid zero-width glyph.
12337 2012-02-01 Eli Zaretskii <eliz@gnu.org>
12339 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12340 first 2 arguments are identical. This makes inserting large
12341 output from a subprocess an order of magnitude faster on
12342 MS-Windows, where all sbrk'ed memory is always contiguous.
12344 2012-01-31 Glenn Morris <rgm@gnu.org>
12346 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

12382 2012-01-21 Chong Yidong <cyd@gnu.org>
12384 * floatfns.c (Fcopysign): Make the second argument non-optional,
12385 since nil is not allowed anyway.
12387 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
12389 * process.c (read_process_output): Use p instead of XPROCESS (proc).

12392 2012-01-19 Martin Rudalics <rudalics@gmx.at>
12394 * window.c (save_window_save, Fcurrent_window_configuration)
12395 (Vwindow_persistent_parameters): Do not use Qstate.
12396 Rewrite doc-strings.
12398 2012-01-19 Kenichi Handa <handa@m17n.org>
12400 * character.c (char_width): New function.
12401 (Fchar_width, c_string_width, lisp_string_width):
12402 Use char_width (Bug#9496).

12407 (Fset_window_configuration, save_window_save): Handle persistent
12410 2012-01-14 Eli Zaretskii <eliz@gnu.org>
12412 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
12413 thrashing the stack of the thread. (Bug#9087)
12415 2012-01-12 Paul Eggert <eggert@cs.ucla.edu>
12417 * xdisp.c (rows_from_pos_range): Add parens as per gcc -Wparentheses.
12419 2012-01-11 Eli Zaretskii <eliz@gnu.org>

12422 highlight ends on a newline. (Bug#10464)
12423 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
12424 he end column for display of highlight that ends on a newline
12427 2012-01-11 Glenn Morris <rgm@gnu.org>
12429 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
12430 from load-path also when installation-directory is nil. (Bug#10208)
12432 2012-01-10 Glenn Morris <rgm@gnu.org>
12434 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
12436 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
12437 Update template values to be closer to their typical values these days.
12439 2012-01-09 Eli Zaretskii <eliz@gnu.org>
12441 * xdisp.c (rows_from_pos_range): Accept additional argument
12442 DISP_STRING, and accept any glyph in a row whose object is that
12443 string as eligible for mouse highlight. Fixes mouse highlight of
12444 display strings from overlays. (Bug#10464)
12446 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
12448 emacs: fix an auto-save permissions race condition (Bug#10400)
12449 * fileio.c (auto_saving_dir_umask): New static var.
12450 (Fmake_directory_internal): Use it.
12451 (do_auto_save_make_dir): Set it, instead of invoking chmod after
12452 creating the directory. The old code temporarily assigns
12453 too-generous permissions to the directory.
12454 (do_auto_save_eh): Clear it.
12455 (Fdo_auto_save): Catch all errors, not just file errors, so
12456 that the var is always cleared.

12957 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
12958 Otherwise, valgrind does not work on some platforms.
12959 Problem reported by Andreas Schwab in
12960 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12961 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12962 is set, removing the need for VIRT_ADDRESS_VARIES.
12963 (PURE_P): Use a more-efficient implementation that needs just one
12964 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12965 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12966 to 4 (xorl, subq, cmpq, setbe).
12967 * alloc.c (pure): Always extern now, since that's the
12968 VIRT_ADDR_VARIES behavior.
12969 (PURE_POINTER_P): Use a single comparison, not two, for
12970 consistency with the new puresize.h.
12971 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12972 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
12973 Remove VIRT_ADDR_VARIES no longer needed.

12978 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12979 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12980 behave as if the cursor position were at the window margin.
12982 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12983 and the cursor position is out of bounds, behave as if the cursor
12984 position were at the window margin. (Bug#10075)
12986 2011-11-18 Chong Yidong <cyd@gnu.org>
12988 * window.c (Fwindow_combination_limit): Make first argument

13006 hash values of the two rows. (Bug#10035)
13007 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13009 * xdisp.c (row_hash): New function, body extracted from
13010 compute_line_metrics.
13011 (compute_line_metrics): Call row_hash, instead of computing the
13014 * dispnew.c (verify_row_hash): Call row_hash for computing the
13015 hash code of a row, instead of duplicating code from xdisp.c.
13017 * dispextern.h (row_hash): Add prototype.
13019 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

13047 (Fsplit_window_internal, saved_window)
13048 (Fset_window_configuration, save_window_save): Rename all
13049 occurrences of window_nest to window_combination_limit.

13055 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13057 * xdisp.c (display_line): Move the call to
13058 highlight_trailing_whitespace before the call to
13059 compute_line_metrics, since the latter needs to see the final
13060 faces of all the glyphs to compute ROW's hash value.
13061 Fixes assertion violations in row_equal_p. (Bug#10035)
13063 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13065 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13066 just return (bug#10044).
13068 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13070 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13071 with user-defined heap size. Bump the default size of the temacs
13072 heap to 27MB, to avoid memory warning when running temacs.
13073 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13075 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13076 current_matrix and desired_matrix. (Bug#9990)
13077 (verify_row_hash) [XASSERTS]: New function.

13122 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13124 Avoid some portability problems by eschewing 'extern inline' functions.
13125 The trivial performance wins aren't worth the portability hassles; see
13126 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13128 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

13194 * xmenu.c (cleanup_widget_value_tree): New function.
13195 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

13202 (window_box_width, window_box_left, window_box_left_offset)
13203 (window_box_right, window_box_right_offset): Declare extern.
13204 Otherwise, these inline functions do not conform to C99 and
13205 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13206 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13207 * intervals.c (adjust_intervals_for_insertion)

13210 (static_offset_intervals): Remove.
13211 (offset_intervals): Rewrite using the old contents of
13212 static_offset_intervals. The old version didn't conform to C99
13213 because an extern inline function contained a reference to an
13214 identifier with static linkage.

13380 (x_handle_net_wm_state): Return what get_current_wm_state returns.
13381 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
13383 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
13385 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
13386 so that this new function doesn't get optimized away by a
13387 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
13389 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
13391 * frame.h (MOUSE_HL_INFO): Remove excess parens.
13393 2011-10-29 Eli Zaretskii <eliz@gnu.org>
13395 Fix the `xbytecode' command.
13396 * .gdbinit (xprintbytestr): New command.
13397 (xwhichsymbols): Rename from `which'; all callers changed.
13398 (xbytecode): Print the byte-code string as well.
13400 2011-10-29 Kim Storm <storm@cua.dk>
13402 * alloc.c (which_symbols): New function.
13404 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
13406 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
13409 2011-10-29 Glenn Morris <rgm@gnu.org>
13411 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
13412 Not clear what it was for, and it causes various bugs. (Bug#9839)
13414 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13416 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
13417 possible random value that matches one of those tested as
13418 condition to clear the mouse face.
13420 2011-10-28 Chong Yidong <cyd@gnu.org>
13422 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
13424 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
13426 * window.c (make_window): Initialize phys_cursor_on_p.
13428 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
13430 * lisp.h (struct Lisp_Symbol): Update comments.
13432 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
13434 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
13436 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13438 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13439 <oslsachem@gmail.com> for helping to debug this.
13441 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
13442 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
13443 (g_b_init_get_glyph_outline_w): New static variables.
13444 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
13445 (GetGlyphOutlineW_Proc): New typedefs.
13446 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
13447 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13449 (w32font_open_internal, compute_metrics):
13450 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13451 instead of calling the "wide" APIs directly.
13453 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13455 * w32.h (syms_of_w32font): Add prototype.
13457 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13459 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13460 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13461 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13462 (Fmove_to_window_line): Doc fix.
13464 2011-10-27 Chong Yidong <cyd@gnu.org>
13466 * process.c (make_process): Set gnutls_state to NULL.
13468 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13469 non-NULL, regardless of GNUTLS_INITSTAGE.
13470 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13471 an error. Set process slots as soon as we allocate them.
13473 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13475 2011-10-27 Chong Yidong <cyd@gnu.org>
13477 * gnutls.c (emacs_gnutls_deinit): New function.
13478 Deallocate credentials structures as well as calling gnutls_deinit.
13479 (Fgnutls_deinit, Fgnutls_boot): Use it.
13481 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13482 (deactivate_process): Call emacs_gnutls_deinit.
13484 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13486 * image.c (x_create_x_image_and_pixmap):
13487 * w32.c (sys_rename, w32_delayed_load):
13488 * w32font.c (fill_in_logfont):
13489 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13491 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13493 * w32fns.c (w32_default_color_map): New function,
13494 extracted from Fw32_default_color_map.
13495 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13497 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13499 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13501 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13503 * keyboard.c (test_undefined): New function (bug#9751).
13504 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13506 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13508 * sysdep.c (init_sys_modes): Fix the check for the controlling
13509 terminal (Bug#6649).
13511 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13513 * dispextern.h (struct bidi_it): New member next_en_type.
13515 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13516 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13517 current character, check also for next_en_type being WEAK_EN.
13518 (bidi_resolve_weak): Don't enter the expensive loop if the current
13519 position is before next_en_pos. Record the bidi type of the first
13520 non-ET, non-BN character we find, in addition to its position.
13521 (bidi_level_of_next_char): Invalidate next_en_type when
13522 next_en_pos is over-stepped.
13524 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13526 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13527 * editfns.c: Rewrite current-time-zone so that it invokes
13528 the equivalent of (format-time-string "%Z") to get the time zone name.
13529 This fixes a bug when the time zone name contains characters that
13530 need converting from the system time locale to Emacs internal format.
13531 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13532 that patch fixed format-time-string to do the conversion, but
13533 I forgot to fix current-time-zone.
13534 (format_time_string): New function, containing most of
13535 what Fformat_time_string used to contain.
13536 (Fformat_time_string): Rewrite in terms of format_time_string.
13537 This doesn't change this function's behavior.
13538 (current-time-zone): Rewrite to use format_time_string.
13539 This fixes the bug reported by Michael Schierl in
13540 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13541 Jason Rumney's 2007-06-07 change worked around this bug, but
13543 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13545 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13547 * xdisp.c (start_display): If the character at POS is displayed
13548 via a display vector, reset IT->current.dpvec_index to zero.
13549 (try_window_reusing_current_matrix): If a line ends in a display
13550 vector or the next line starts in a display vector, continue
13551 redrawing the window even though the character position of
13552 start_row was reached.
13555 2011-10-18 Chong Yidong <cyd@gnu.org>
13557 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13558 with nobreak-char-display too.
13560 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13562 Fix part 3 of bug#9771.
13563 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13564 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13565 non-neutral characters if the current character is a paragraph
13566 separator (a.k.a. Newline). This avoids running the same
13567 expensive loop twice, once when we consume the preceding newline
13568 and the other time when the line actually needs to be displayed.
13569 Avoid the loop when we see neutrals on the base embedding level
13570 following a character whose directionality is the same as the
13571 paragraph's. This avoids running the expensive loop when a line
13572 ends in a long sequence of neutrals, like control characters.
13573 Add assertion against STRONG_AL type. Slightly rearrange code
13574 that determines the type of a neutral given the first non-neutral
13576 (bidi_level_of_next_char): Set next_en_pos to zero when
13577 invalidating its info.
13579 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13581 * xdisp.c (push_display_prop): Determine whether to record string
13582 or buffer position by IT->string, not by IT->method. Allow
13583 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13584 (move_it_vertically_backward): Don't look for character position
13585 immediately after the newline when in a continuation line.
13588 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13590 * window.c (coordinates_in_window): Rewrite and delabelize
13591 vertical border check. (Bug#5357) (Bug#9618)
13593 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13595 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13596 errors in XSetWindowBorder (bug#9310).
13598 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13600 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13601 avoid crash when xmalloc overrun checking is enabled.
13603 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13605 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13606 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13607 cursor motion with <left> and <right> arrow keys.
13609 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13610 some callers set that themselves.
13612 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13614 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13615 display string and the previous row comes from the same string and
13616 is empty. (Bug#9739) (Bug#9738)
13618 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13620 * doc.c (get_doc_string): Encode file name (bug#9735).
13622 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13624 * bidi.c (bidi_level_of_next_char):
13625 * xdisp.c (get_visually_first_element): Remove old incorrect
13626 comments regarding the Unicode Line Separator character.
13628 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13630 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13632 * alloc.c (Fgc_status): Do not access beyond zombies array
13633 boundary if nzombies > MAX_ZOMBIES.
13634 * alloc.c (dump_zombies): Add missing format specifier.
13636 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13638 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13639 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13641 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13642 Some packages use them to denote characters with modifiers.
13644 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13646 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13647 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13648 matching a pp-number. Rename parameter var to var1.
13650 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13652 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13654 2011-10-08 Glenn Morris <rgm@gnu.org>
13656 * callint.c (Fcall_interactively): Give a more explicit error for the
13657 'c' case with a non-character input. (Bug#8479)
13659 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13661 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13663 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13664 lines that are hscrolled on the left.
13666 * dispnew.c (buffer_posn_from_coords): Account for a possible
13667 presence of header-line. (Bug#4426)
13669 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13671 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13672 Don't advertise functionality which we discourage or doesn't work.
13674 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13676 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13677 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13678 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13679 this makes Emacs dump core during garbage collection on rare
13680 occasions. sizeof is obviously inferior to offsetof here, so
13681 stick with offsetof.
13682 (GC_POINTER_ALIGNMENT): New macro.
13683 (mark_memory): Omit 3rd (offset) arg; caller changed.
13684 Don't assume EMACS_INT alignment is the same as pointer alignment.
13686 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13688 * keyboard.c (read_key_sequence_remapped): New var.
13689 (read_key_sequence): Compute remapping in the right buffer.
13690 (command_loop_1): Use read_key_sequence's remapping directly.
13692 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13694 * dired.c (file_name_completion): Don't expand file name.
13695 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13696 before checking file name handler.
13698 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13699 they've been requested explicitly (bug#9591).
13701 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13703 * keymap.c (Fsingle_key_description): Use make_specified_string
13704 instead of build_string to build string from push_key_description.
13707 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13709 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13710 This fixes a Y2038 bug on 64-bit hosts.
13711 * buffer.c (reset_buffer):
13712 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13713 (Fclear_buffer_auto_save_failure):
13714 Use 0, not -1, to represent an unset failure time, since time_t
13715 might not be signed.
13717 Remove dependency on glibc malloc internals.
13718 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13719 Move back here from lisp.h, but with their new implementations.
13720 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13721 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13722 * charset.c (charset_table_init): New static var.
13723 (syms_of_charset): Use it instead of xmalloc. This removes a
13724 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13725 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13726 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13727 Move back to alloc.c.
13728 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13729 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13731 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13733 * nsterm.m (windowDidResize): Call x_set_window_size only when
13734 ns_in_resize is true. Otherwise set pixelwidth/height and
13735 call change_frame_size (Bug#9628).
13737 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13739 Port --enable-checking=all to Fedora 14 x86-64.
13740 * charset.c (syms_of_charset): Also account for glibc malloc's
13741 internal overhead when calculating the initial malloc maximum.
13743 Port --enable-checking=all to Fedora 14 x86.
13744 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13746 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13747 (overrun_check_realloc, overrun_check_free):
13748 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13749 That way, xmalloc returns a properly-aligned pointer even if
13750 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13751 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13752 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13753 into account when calculating the initial malloc maximum.
13754 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13755 Move here from alloc.c, so that charset.c can use it too.
13756 Properly align; the old code wasn't right for common 32-bit hosts
13757 when configured with --enable-checking=all.
13758 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13759 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13761 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13763 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13766 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13768 * xdisp.c (compute_display_string_end): If there's no display
13769 string at CHARPOS, return -1.
13771 * bidi.c (bidi_fetch_char): When compute_display_string_end
13772 returns a negative value, treat the character as a normal
13773 character not covered by a display string. (Bug#9624)
13775 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13777 * lread.c (Fread_from_string): Fix typo in docstring.
13779 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13781 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13782 newline, reseat the iterator instead of bidi-iterating there one
13783 character at a time. (Bug#9610)
13784 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13785 TO_CHARPOS if the bidi iterator is at base embedding level.
13787 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13789 * lread.c (readevalloop): Use correct code for NBSP.
13790 (read1): Likewise. (Bug#9608)
13792 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13794 * dbusbind.c (Fdbus_register_signal): When service is not
13795 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13797 2011-09-25 Glenn Morris <rgm@gnu.org>
13799 * buffer.c (truncate-lines): Doc fix.
13801 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13803 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13804 (Fset_window_next_buffers): Doc fix.
13806 2011-09-24 Glenn Morris <rgm@gnu.org>
13808 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13810 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13812 Fix minor problems found by static checking.
13813 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13814 * indent.c (Fvertical_motion): Fix == vs = typo.
13816 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13818 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13819 Default value is now t. Doc fix.
13821 * indent.c (Fvertical_motion): Compute and apply the overshoot
13822 logic when moving up, not only when moving down. Fix the
13823 confusing name and values of the it_overshoot_expected variable;
13824 logic changes accordingly. (Bug#9254) (Bug#9549)
13826 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13827 CHARPOS is covered by a display string which includes newlines.
13828 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13829 is covered by a display string with embedded newlines.
13831 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13833 * dbusbind.c (Fdbus_register_signal): Add match rule to
13834 Vdbus_registered_objects_table. (Bug#9581)
13835 (Fdbus_register_method, Vdbus_registered_objects_table):
13838 2011-09-24 Jim Meyering <meyering@redhat.com>
13840 do not ignore write error for any output size
13841 The previous change was incomplete.
13842 While it makes emacs --batch detect the vast majority of stdout
13843 write failures, errors were still ignored whenever the output size is
13844 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13845 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13846 && echo FAIL: ignored write error
13847 FAIL: ignored write error
13848 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13849 && echo FAIL: ignored write error
13850 FAIL: ignored write error
13851 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13853 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13855 * emacs.c (Fkill_emacs): In noninteractive mode exit
13856 non-successfully if a write error occurred on stdout. (Bug#9574)
13858 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13860 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13863 * dispextern.h (struct it): Update the comment documenting what
13866 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13868 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13869 a display string, extend search for cursor position to end of row.
13870 (find_row_edges): If the row ends in a newline from a display
13871 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13872 Handle the case of a display string with multiple newlines.
13873 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13874 non-empty line. Fixes confusing cursor motion with arrow keys at
13875 the beginning of a line that starts with whitespace.
13877 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13879 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13882 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13884 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13885 boolean (Bug#9154).
13887 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13889 * xdisp.c (display_line): Record maximum and minimum buffer
13890 positions even if no glyphs were produced (e.g., by a zero-width
13891 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13892 buffer positions that will be removed from the glyph row because
13894 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13895 column is beyond frame width: don't subtract 1 "pixel" when
13896 computing width of the stretch.
13897 (reseat_at_next_visible_line_start): Undo the change made on
13898 2011-09-17 that saved paragraph information and restored it after
13899 the call to `reseat'. (Bug#9545)
13901 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13903 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13904 and turn window cursor on if cleared (Bug#9415).
13906 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13908 * search.c (boyer_moore): Take unibyte characters from pattern
13909 literally. (Bug#9458)
13911 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13913 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13915 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13917 Fix minor problem found by static checking.
13918 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13919 initialized, to pacify gcc -Wuninitialized.
13921 * fileio.c: Report proper errno when syscall falls.
13922 (Finsert_file_contents): Save and restore errno,
13923 so that report_file_error outputs the correct diagnostic.
13924 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13926 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13928 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13930 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13932 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13933 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13935 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13937 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13938 about the current paragraph and restore it after the call to reseat.
13940 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13941 (bidi_find_paragraph_start): Search back for paragraph beginning
13942 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13943 (bidi_move_to_visually_next): Only trigger paragraph-related
13944 computations when the last character is a newline or at EOB, not
13945 just any NEUTRAL_B. (Bug#9470)
13947 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13948 truncated lines if point is covered by a display string. (Bug#9524)
13950 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13952 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13953 (cons_to_x_long): New function.
13954 (lisp_data_to_selection_data): Use it. Correct the test for
13955 short-versus-long data; it was negated. Break out of vector
13956 loop, for efficiency, when a long datum is discovered.
13958 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13960 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13962 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13964 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13965 GCC PR/17406) by declaring this function with external scope.
13967 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13969 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13970 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13972 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13974 * editfns.c (Fformat): Correctly handle text properties on "%%".

13980 * term.c (encode_terminal_code):
13981 * composite.c (composition_update_it, get_composition_id):
13982 * xdisp.c (get_next_display_element)
13983 (fill_composite_glyph_string): Add comments about special meaning
13984 of TAB characters in a composition.
13986 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13988 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13989 This occurs when processing a multibyte format.
13990 Problem reported by Wolfgang Jenker.
13992 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13994 * xdisp.c (try_cursor_movement): Only check for exact match if
13995 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13997 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13999 Remove unused external symbols.
14000 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14001 * xdisp.c (calc_pixel_width_or_height): Now static.
14002 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14003 * indent.c (check_display_width):
14004 * w32term.c: Fix comment to match code.
14005 * xterm.c, xterm.h (x_catching_errors): Remove.
14007 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14009 * xselect.c: Use signed conversions more consistently (Bug#9498).
14010 (selection_data_to_lisp_data): Assume incoming selection data are
14011 signed integers, not unsigned. This is to be consistent with
14012 outgoing selection data, which was modified to use signed integers
14013 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14014 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14015 expects long, not unsigned long.
14017 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14019 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14020 computation of loop end. Reported by Johan Bockgård
14023 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14025 * frame.c (Fother_visible_frames_p): Function deleted.
14027 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14029 * indent.c (compute_motion): Process display vector front to back
14030 rather than the other way around. (Bug#2496)
14032 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14034 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14036 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14038 * minibuf.c (Fread_from_minibuffer): Doc fix.
14040 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14042 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14043 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14045 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14047 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14048 value for non-existent files.
14050 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14052 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14053 set its "size" to -1. This will set the modtime_size field of
14054 the corresponding buffer to -1, which is what
14055 verify-visited-file-modtime expects for files that do not exist.
14058 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14060 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14062 * lisp.h: ... from here. push_key_description is no longer
14063 defined in keyboard.c, so its declaration should not be in
14064 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14065 logically belongs with push_key_description.
14067 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14069 * buffer.h: Include <sys/types.h> instead of <time.h>.
14070 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14071 Problem reported by Herbert J. Skuhra.
14073 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14075 * xml.c (parse_region): Make the parsing work for
14076 non-comment-starting XML files again (bug#9144).
14078 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14080 * image.c (gif_load): Fix calculation of bottom and right corner.
14083 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14085 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14086 redisplay in small windows.
14088 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14090 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14092 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14094 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14095 Operate on live windows only.
14097 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14099 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14101 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14103 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14104 only under bidi iteration.
14106 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14108 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14110 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14112 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14113 Without this fix, the command to link temacs failed due to an
14114 undefined symbol __builtin_isnan. This is because
14115 /usr/include/iso/math_c99.h #defines isnan(x) to
14116 __builtin_isnan(x), but the bundled gcc, which identifies itself
14117 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14119 * floatfns.c (isnan): #undef, and then #define to a clone of
14121 (Fisnan): Always define, since it's always available now.
14122 (syms_of_floatfns): Always define isnan at the Lisp level.
14124 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14126 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14128 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14130 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14131 The previous code assumed that file offsets (off_t values) fit in
14132 EMACS_INT variables, which is not true on typical 32-bit hosts.
14133 The code messed up by falsely reporting buffer overflow in cases
14134 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14135 when "big" contains more than 2**29 bytes, even though this
14136 inserts just one byte and does not overflow the buffer.
14137 (Finsert_file_contents): Store file offsets as off_t
14138 values, not as EMACS_INT values. Check for overflow when
14139 converting between EMACS_INT and off_t. When checking for
14140 buffer overflow or for overlap, take the offsets into account.
14141 Don't use EMACS_INT for small values where int suffices.
14142 When checking for overlap, fix a typo: ZV was used where
14143 ZV_BYTE was intended.
14144 (Fwrite_region): Don't assume off_t fits into 'long'.
14145 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14147 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14149 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14151 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14153 sprintf-related integer and memory overflow issues (Bug#9412).
14155 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14156 (esprintf, exprintf, evxprintf): New functions.
14157 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14158 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14159 (modify_event_symbol): Do not assume that the length of
14160 name_alist_or_stem is safe to alloca and fits in int.
14161 (Fexecute_extended_command): Likewise for function name and binding.
14162 (Frecursion_depth): Wrap around reliably on integer overflow.
14163 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14164 since some callers pass EMACS_INT values.
14165 (Fsingle_key_description): Don't crash if symbol name contains more
14166 than MAX_ALLOCA bytes.
14167 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14168 (get_minibuffer): Arg is now EMACS_INT, not int.
14169 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14170 (esprintf, exprintf, evxprintf): New decls.
14171 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14173 * dbusbind.c (signature_cat): New function.
14174 (xd_signature, Fdbus_register_signal):
14175 Do not overrun buffer; instead, report string overflow.
14177 * dispnew.c (add_window_display_history): Don't overrun buffer.
14178 Truncate instead; this is OK since it's just a log.
14180 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14181 even if the time zone offset is outlandishly large.
14182 Don't mishandle offset == INT_MIN.
14184 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14185 when creating daemon; the previous buffer-overflow check was incorrect.
14187 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14188 which has the guts of the old verror function.
14190 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14191 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14193 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14194 (font_unparse_xlfd): Don't blindly alloca long strings.
14195 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14196 fits in int, when using sprintf. Use single snprintf to count
14197 length of string rather than counting it via multiple sprintfs;
14198 that's simpler and more reliable.
14199 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14200 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14201 sprintf, in case result does not fit in int.
14203 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14204 (fontset_from_font): Print it.
14206 * frame.c (tty_frame_count): Now printmax_t, not int.
14207 (make_terminal_frame, set_term_frame_name): Print it.
14208 (x_report_frame_params): In X, window IDs are unsigned long,
14209 not signed long, so print them as unsigned.
14210 (validate_x_resource_name): Check for implausibly long names,
14211 and don't assume name length fits in 'int'.
14212 (x_get_resource_string): Don't blindly alloca invocation name;
14213 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14216 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14217 (xg_check_special_colors, xg_set_geometry):
14218 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14220 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14221 Use esprintf, not sprintf, in case result does not fit in int.
14223 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14224 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14225 it as a large positive number.
14226 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14227 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14229 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14230 in case result does not fit in int.
14232 * print.c (float_to_string): Detect width overflow more reliably.
14233 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14234 buffer overrun. Don't assume list length fits in 'int'. Treat
14235 print length of 0 as 0, not as infinity; to be consistent with other
14236 uses of print length in this function. Don't overflow print length
14237 index. Don't assume hash table size fits in 'long', or that
14238 vectorlike size fits in 'unsigned long'.
14240 * process.c (make_process): Use printmax_t, not int, to format
14241 process-name gensyms.
14243 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14245 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14246 to avoid potential buffer overrun.
14248 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14249 if X resource line is longer than 512 bytes.
14251 * xfns.c (x_window): Make sprintf buffer a bit bigger
14252 to avoid potential buffer overrun.
14254 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14256 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14258 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14260 Integer overflow fixes for scrolling, etc.
14261 Without these, Emacs silently mishandles large integers sometimes.
14262 For example, "C-u 4294967297 M-x recenter" was treated as if
14263 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14265 * xdisp.c (try_window_id): Check Emacs fixnum range before
14266 converting to 'int'.
14268 * window.c (window_scroll_line_based, Frecenter):
14269 Check that an Emacs fixnum is in range before assigning it to 'int'.
14270 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14271 values converted from Emacs fixnums.
14272 (Frecenter): Don't wrap around a line count if it is out of 'int'
14273 range; instead, treat it as an extreme value.
14274 (Fset_window_configuration, compare_window_configurations):
14275 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14277 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14278 that can exceed INT_MAX. Check that EMACS_INT value is in range
14279 before assigning it to the (possibly-narrower) index.
14280 (match_limit): Don't assume that a fixnum can fit in 'int'.
14282 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14285 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14286 (Fvertical_motion): Don't wrap around LINES values that don't fit
14287 in 'int'. Instead, treat them as extreme values. This is good
14288 enough for windows, which can't have more than INT_MAX lines anyway.
14290 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14292 * Require libxml/parser.h to avoid compilation warning.
14294 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14296 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14297 since this reportedly can destroy thread storage.
14299 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14301 * syntax.c (find_defun_start): Update all cache variables if
14302 exiting early (Bug#9401).
14304 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14306 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14308 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14309 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14310 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14312 * term.c (tty_append_glyph): New function.
14313 (produce_stretch_glyph): Static function and its prototype deleted.
14315 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14318 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14320 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14321 when checking :margin (Bug#9390).
14322 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14323 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14324 so that the name doesn't mislead. All uses changed.
14326 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14328 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after

14333 * xdisp.c (move_it_to): Don't bail out early when reaching
14334 position beyond to_charpos, if we are scanning backwards.
14335 (move_it_vertically_backward): When DY == 0, make sure we get to
14336 the first character in the line after the newline.
14338 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14340 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14341 (ccl_driver): Do not generate an out-of-range pointer.
14342 (Fccl_execute_on_string): Remove unnecessary check for
14343 integer overflow, noted by Stefan Monnier in
14344 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14345 Remove a FIXME that didn't need fixing.
14346 Simplify the newly-introduced buffer reallocation code.
14348 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14350 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14352 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14354 Integer and memory overflow issues (Bug#9196).
14356 * doc.c (get_doc_string): Rework so that
14357 get_doc_string_buffer_size is the actual buffer size, rather than
14358 being 1 less than the actual buffer size; this makes xpalloc more
14361 * image.c (x_allocate_bitmap_record, cache_image):
14362 * xselect.c (Fx_register_dnd_atom):
14363 Simplify previous changes by using xpalloc.
14365 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14366 since either will do and ptrdiff_t is convenient with xpalloc.
14368 * charset.c (charset_table_size)
14369 (struct charset_sort_data.priority): Now ptrdiff_t.
14370 (charset_compare): Don't overflow if priorities differ greatly.
14371 (Fsort_charsets): Don't assume list length fits in int.
14372 Check for size-calculation overflow when allocating sort data.
14373 (syms_of_charset): Allocate an initial charset table that is
14374 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14376 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14378 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14379 The actual value is always <= INT_MAX, and leaving it unsigned made
14380 overflow checking harder.
14382 * dispextern.h (struct glyph_matrix.rows_allocated)
14383 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14384 with xpalloc. The values are still always <= INT_MAX.
14386 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14388 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14389 (SAFE_NALLOCA): New macro.
14391 * region-cache.c (struct boundary.pos, find_cache_boundary)
14392 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14393 (set_cache_region, invalidate_region_cache)
14394 (revalidate_region_cache, know_region_cache, region_cache_forward)
14395 (region_cache_backward, pp_cache):
14396 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14397 so that ptrdiff_t * can be passed to xpalloc.
14398 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14399 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14400 (pp_cache): Don't assume cache_len fits in int.
14401 * region-cache.h: Adjust extern decls to match.
14403 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14404 EMACS_INT, since either will do, for xpalloc.
14406 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14407 (xnmalloc, xnrealloc, xpalloc): New functions.
14409 * bidi.c (bidi_shelve_header_size): New constant.
14410 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14411 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14413 * bidi.c (bidi_cache_shrink):
14414 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14416 Don't update size of array until after memory allocation succeeds,
14417 because xmalloc/xrealloc may not return.
14418 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14419 now that we have proper integer overflow checking.
14420 (record_overlay_string, overlay_strings): Catch overflows when
14421 calculating size of overlay_str_buf.
14423 * callproc.c (Fcall_process): Check for size overflow when
14424 calculating size of args2.
14425 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14426 Normally we prefer signed values, but sticking with ptrdiff_t would
14427 require adding more-complicated checks.
14429 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14430 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14431 Redo buffer-overflow calculations to avoid integer overflow.
14432 Add a FIXME comment where memory seems to be over-allocated.
14434 * character.c (Fstring): Check for size-calculation overflow.
14436 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14437 unnecessary integer overflow. Check for size overflow.
14438 (encode_coding_object): Don't update size until xmalloc succeeds.
14440 * composite.c (get_composition_id): Check for overflow in glyph
14441 length calculations.
14443 Integer and memory overflow fixes for display code.
14444 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14445 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14446 (scrolling_window): Check for overflow in size calculations.

14458 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14459 (get_doc_string): Check for size calculation overflow.
14460 Don't update size until allocation succeeds.
14461 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14462 EMACS_INT, where ptrdiff_t will do.
14463 (Fsubstitute_command_keys): Check for string overflow.
14465 * editfns.c (set_time_zone_rule): Don't assume environment length
14467 (message_length): Now ptrdiff_t, not int.
14468 (Fmessage_box): Don't update size until allocation succeeds.
14469 Don't assume message length fits in int.
14470 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14472 * emacs.c (main): Do not reallocate argv, since there is a null at
14473 the end that can be overwritten, and this way there's no need to
14474 worry about size-calculation overflow.
14475 (sort_args): Check for size-calculation overflow.
14477 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14479 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14481 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14482 (x_set_scroll_bar_width, x_figure_window_size):
14483 Check for integer overflow.
14484 (x_set_alpha): Do not assume XINT fits in int.
14486 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14487 This is for the members text_lines, text_cols, total_lines, total_cols,
14488 where the system imposes an 'int' limit.
14490 * fringe.c (Fdefine_fringe_bitmap):
14491 Don't update size until alloc works.
14493 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14494 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14496 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14497 Check for size-calculation overflow.
14498 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14499 do, as we prefer signed integers.
14500 (id_to_widget.max_size, id_to_widget.used)
14501 (xg_store_widget_in_map, xg_remove_widget_from_map)
14502 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14503 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14504 Use and return ptrdiff_t, not int.
14505 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14506 * gtkutil.h: Change prototypes to match the above.
14508 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14509 are duplicate now that they've been promoted to lisp.h.
14510 (x_allocate_bitmap_record, x_alloc_image_color)
14511 (make_image_cache, cache_image, xpm_load):
14512 Don't update size until alloc is done.

14523 Use ptrdiff_t, not int, to count maps.
14524 (read_char_minibuf_menu_prompt): Check for overflow in size
14525 calculations. Don't update size until allocation succeeds.
14526 Redo calculations to avoid overflow.
14527 * keyboard.h: Change prototypes to match the above.

14555 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14556 for command line length. Do not attempt to address one before the
14557 beginning of an array, as that's not portable.
14559 * term.c (max_frame_lines): Remove; unused.
14560 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14562 (encode_terminal_code, calculate_costs): Check for size

14569 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14570 subtracting pointers.

14592 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14593 sizes, since they can exceed INT_MAX in size. Check for size

14597 (xg_select): Check for size calculation overflow.
14598 Don't update size until alloc done.
14600 * xrdb.c (get_environ_db): Don't assume path length fits in int,

14603 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14604 (X_LONG_MIN): New macros.
14605 Use them to make the following changes clearer.
14606 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14607 This change doesn't affect the value now, but it may help remind
14608 future maintainers not to raise the value too much later.
14609 (SELECTION_QUANTUM): Remove, replacing with ...
14610 (selection_quantum): ... new function, which avoids overflow.
14612 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14613 assumption that selection length fits in 'int'.

14626 (lisp_data_to_selection_data, x_property_data_to_lisp):

14630 Don't store size until memory allocation succeeds.
14631 (x_get_window_property): Plug memory leak on memory exhaustion.
14632 Don't double-block input; malloc is safe here. Don't assume 2**34
14633 - 4 fits in unsigned long. Add an xassert to check
14634 XGetWindowProperty overflow. Be more careful about overflow
14635 calculations, and distinguish size from memory overflow better.

14637 unsigned int is less than INT_MAX.
14638 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14639 harmful) conversions of unsigned short to int.
14640 (lisp_data_to_selection_data): Don't assume that integers
14641 in the range -65535 through -1 fit in an X unsigned short.
14642 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14643 result parameters unless successful. Rely on cons_to_unsigned
14644 to report problems with elements; the old code wasn't right anyway.
14645 (x_check_property_data): Check for int overflow; we cannot use
14646 a wider type due to X limits.
14647 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

14679 * lisp.h (hash_lookup, hash_put):
14680 * minibuf.c (Ftest_completion):
14681 Use ptrdiff_t for hash table indexes, not int (which is too
14682 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14683 32-bit --with-wide-int hosts).
14685 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14686 Add a FIXME comment about memory leaks.
14687 (syms_of_charset): Don't assume xmalloc returns.

14694 with outlandish widths.
14695 * character.h (sanitize_tab_width): Rename from sanitize_width,
14696 now that we have two such functions. All uses changed.

14717 exceed limits imposed by XClientMessageEvent, as well as the usual
14718 ptrdiff_t and size_t limits.
14720 * keyboard.c: Overflow, signedness and related fixes.

14724 Change bufsize argument back to int, undoing my 2011-03-30 change.
14725 We prefer signed types, and int is wide enough here.
14726 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14727 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14728 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14729 length, not size_t. Use ptrdiff_t for index, not int.
14730 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14731 possibility of integer overflow.
14733 Overflow, signedness and related fixes for images.
14735 * dispextern.h (struct it.stack[0].u.image.image_id)
14736 (struct_it.image_id, struct image.id, struct image_cache.size)
14737 (struct image_cache.used, struct image_cache.ref_count):
14738 * gtkutil.c (update_frame_tool_bar):
14739 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)

14742 * nsmenu.m (update_frame_tool_bar):
14743 * xdisp.c (calc_pixel_width_or_height):
14744 * xfns.c (image_cache_refcount):
14745 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
14746 on typical 64-bit hosts.
14748 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
14749 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

14752 when the callers expect that.
14753 (image_ascent): Redo ascent calculation to avoid int overflow.
14754 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
14755 (lookup_image): Remove unnecessary tests.
14756 (xbm_image_p): Locals are now of int, not EMACS_INT,
14757 since parse_image_check makes sure they fit into int.
14758 (png_load, gif_load, svg_load_image):
14759 Prefer int to unsigned where either will do.
14760 (tiff_handler): New function, combining the cores of the
14761 old tiff_error_handler and tiff_warning_handler.
14762 This function is rewritten to use vsnprintf and thereby avoid
14763 stack buffer overflows. It uses only the features of vsnprintf
14764 that are common to both POSIX and native Microsoft.
14765 (tiff_error_handler, tiff_warning_handler): Use it.
14766 (tiff_load, gif_load, imagemagick_load_image):
14767 Don't assume :index value fits in 'int'.
14768 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14769 (imagemagick_load_image): Check that crop parameters fit into
14770 the integer types that MagickCropImage accepts. Don't assume
14771 Vimagemagick_render_type has a nonnegative value. Don't assume
14772 size_t fits in 'long'.
14773 (gs_load): Use printmax_t to print the widest integers possible.
14774 Check for integer overflow when computing image height and width.
14776 2011-08-26 Eli Zaretskii <eliz@gnu.org>
14778 * xdisp.c (redisplay_window): Don't force window start if point

14786 handle_single_display_spec, not just 1 or zero.
14787 (handle_single_display_spec): If the display spec is of the form
14788 `(space ...)', and specifies display in the text area, return 2
14790 (try_cursor_movement): Check for the need to scroll more
14791 accurately, and prefer exact match for point under bidi.
14792 Don't advance `row' beyond the last row of the window.
14794 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
14795 into disp_prop; all users changed.
14797 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
14798 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
14799 for the text covered by the display property.

14809 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
14810 buffers, return left-to-right.
14811 (set_cursor_from_row): Consider candidate row a win if its glyph
14812 represents a newline and point is on that newline. Fixes cursor
14813 positioning on the newline at EOL of R2L text within L2R
14814 paragraph, and vice versa.
14815 (try_cursor_movement): Check continued rows, in addition to
14816 continuation rows. Fixes unwarranted scroll when point enters a
14817 continued line of R2L text within an L2R paragraph, or vice versa.
14818 (cursor_row_p): Consider the case of point being equal to
14819 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14820 from the end of a short line to the beginning of a continued line
14821 of R2L text within L2R paragraph.
14822 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
14823 composed characters.
14825 * bidi.c (bidi_check_type): Use xassert.
14826 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
14829 2011-08-23 Eli Zaretskii <eliz@gnu.org>

14836 * nsfont.m (ns_otf_to_script): Fix typo.
14838 2011-08-22 Kenichi Handa <handa@m17n.org>
14840 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
14841 extra slot even if the purpose is char-code-property-table.
14843 2011-08-23 Eli Zaretskii <eliz@gnu.org>
14845 * xdisp.c (redisplay_window): When computing centering_position,
14846 account for the height of the header line. (Bug#8874)
14848 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14849 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14850 candidate is selected by the mouse, and that candidate has a
14851 composed character under the mouse.
14853 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14854 coordinates reported by pos-visible-in-window-p for a composed
14855 character in column zero.
14857 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
14859 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
14861 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14863 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14864 consider it a hit if to_charpos is anywhere in the range of the
14865 composed buffer positions.
14867 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14869 * image.c (gif_load): Don't assume that each subimage has the same
14870 dimensions as the base image. Handle disposal method that is
14871 "undefined" by the gif spec (Bug#9335).
14873 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14875 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
14876 (Fcondition_case): Document `debug' symbol in error handler.
14878 2011-08-19 Eli Zaretskii <eliz@gnu.org>
14880 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14881 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14882 from an Org mode buffer to a Speedbar frame.
14884 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14885 a composition, take its buffer position from IT->cmp_it.charpos.
14886 Fixes cursor positioning at the beginning of a line that begins
14887 with a composed character.
14889 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14891 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14892 character bidirectional type, use STRONG_L instead. Fixes crashes
14893 in a buffer produced by `describe-categories'.
14895 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14896 members before the level stack, so they would be saved and
14897 restored when copying iterator state. Fixes incorrect reordering
14898 around TABs covered by display properties.
14900 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14902 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

14972 * xdisp.c (move_it_in_display_line_to): Don't invoke
14973 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14974 ppos_it. Fixes vertical cursor motion when line beginning is
14975 covered by an image. (Bug#9296)
14977 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14979 * nsterm.h (ns_run_ascript): Declare.

14983 (ns_run_ascript): New function.
14984 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14985 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14986 the event loop. Get status from as_status (Bug#7276).
14988 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14989 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14990 the event loop (Bug#7276).
14992 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

15016 (Fnetwork_interface_list): Allocate in increments of bytes instead
15017 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15018 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15020 (struct ifflag_def): notrailers is smart on OSX.
15021 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15022 Get hardware address with getifaddrs if available.
15024 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15026 * xdisp.c (iterate_out_of_display_property): xassert that
15027 IT->position is set to within IT->object's boundaries. Break from
15028 the loop as soon as EOB is reached; avoids infloops in redisplay

15030 Set IT->current to match the bidi iterator unconditionally.
15031 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15032 entry. Force push_it to save on the stack the current
15033 buffer/string position, to be restored by pop_it. Fix flags in
15034 the iterator structure wrt the object coming from a display
15035 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15036 properties. (Bug#9284)
15038 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15040 * fontset.c (fontset_get_font_group): Add proper type checks.

15053 no-display-properties-and-no-overlays under bidi display.
15054 Set disp_pos in the bidi iterator to avoid searches for display
15055 properties and overlays.
15057 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15059 * editfns.c (Fset_time_zone_rule): Document relationship with the

15068 restore_point_unwind (Bug#5984).
15070 2011-08-07 Juri Linkov <juri@jurta.org>
15072 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15073 to show the arg `TIME' instead of `TIMEVAL'.

15077 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15078 display property strides EOL and includes a newline, as in
15079 longlines-mode. (Bug#9254)
15080 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15081 word-wrap under bidirectional display. (Bug#9224)
15083 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15084 is non-zero, even if the data buffer is NULL. Fixes a crash in
15085 vertical-motion with longlines-mode. (Bug#9254)
15087 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15089 * bidi.c <bidi_cache_total_alloc>: Now static.

15095 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15096 amount allocated this far in `bidi_cache_total_alloc'.
15097 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15098 non-zero, only free the data buffer without restoring the cache
15099 contents. All callers changed.
15101 * dispextern.h (bidi_unshelve_cache): Update prototype.
15103 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

15164 DISP_PROP_P, and pass it to compute_display_string_pos.
15165 Only handle text covered by a display string if DISP_PROP_P is returned
15166 non-zero. All callers of bidi_fetch_char changed.

15185 * xdisp.c (forward_to_next_line_start): Accept additional argument
15186 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15188 (reseat_at_next_visible_line_start): Use the bidi iterator state
15189 returned by forward_to_next_line_start to restore the state of
15190 it->bidi_it after backing up to previous newline. (Bug#9212)
15192 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15194 * regex.c (re_comp): Protoize.
15195 (re_exec): Fix return type.
15196 (regexec): Fix type of `ret'. (Bug#9203)
15198 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15200 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15201 This is needed if max-image-size is a floating-point number.
15203 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15205 * print.c (print_object): Print empty symbol as ##.
15207 * lread.c (read1): Read ## as empty symbol.
15209 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15211 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15212 setting frame foreground color (Bug#9175).
15213 (x_set_background_color): Likewise.
15215 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15216 contents (Bug#9176).
15217 (EmacsTooltip -init): Remove bezels and add shadows to
15220 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15221 or scroll bar (Bug#8470).
15223 * nsfont.m (nsfont_open): Remove assignment to voffset and
15224 unnecessary vars hshink, expand, hd, full_height, min_height.
15225 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15227 * nsterm.h (nsfont_info): Remove voffset field.
15229 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15231 Implement strike-through and overline on NextStep (Bug#8863).
15233 * nsfont.m (nsfont_open): Use underline position provided by font,
15234 instead of hard-coded value of 2.
15235 (nsfont_draw): Call ns_draw_text_decoration instead.
15237 * nsterm.h: Add declaration for ns_draw_text_decoration.
15239 * nsterm.m (ns_draw_text_decoration): New function for drawing
15240 underline, overline, and strike-through.
15241 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15242 ns_draw_text_decoration. Change treatment of cursor drawing to
15243 accommodate underlining, etc.
15245 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15247 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15250 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15252 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15253 Without this fix, if a signal arrives just after memory fills up,
15254 'malloc' might be invoked reentrantly.
15256 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15257 In other words, assume that every image size is allowed, on non-X
15258 hosts. This assumption is probably wrong, but it lets Emacs compile.
15260 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15262 * regex.c (re_iswctype): Convert return values to boolean.
15264 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15266 * xdisp.c (compute_display_string_pos): Don't use cached display
15267 string position if the buffer had its restriction changed.
15270 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15272 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15274 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15276 Integer signedness and overflow and related fixes. (Bug#9079)
15278 * bidi.c: Integer size and overflow fixes.
15279 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15280 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15281 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15282 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15283 (bidi_find_other_level_edge):
15284 Use ptrdiff_t instead of EMACS_INT where either will do.
15285 This works better on 32-bit hosts configured --with-wide-int.
15286 (bidi_cache_ensure_space): Check for size-calculation overflow.
15287 Use % rather than repeated addition, for better worst-case speed.
15288 Don't set bidi_cache_size until after xrealloc returns, because it
15290 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15291 (bidi_cache_ensure_space): Also check that the bidi cache size
15292 does not exceed that of the largest Lisp string or buffer. See Eli
15293 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15295 * alloc.c (__malloc_size_t): Remove.
15296 All uses replaced by size_t. See Andreas Schwab's note
15297 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15299 * image.c: Improve checking for integer overflow.
15300 (check_image_size): Assume that f is nonnull, since
15301 it is always nonnull in practice. This is one less thing to
15302 worry about when checking for integer overflow later.
15303 (x_check_image_size): New function, which checks for integer
15304 overflow issues inside X.
15305 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15306 This removes the need for a memory_full check.
15307 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15308 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15309 (xbm_read_bitmap_data): Change locals back to 'int', since
15310 their values must fit in 'int'.
15311 (xpm_load_image, png_load, tiff_load):
15312 Invoke x_create_x_image_and_pixmap earlier,
15313 to avoid much needless work if the image is too large.
15314 (tiff_load): Treat overly large images as if
15315 x_create_x_image_and_pixmap failed, not as malloc failures.
15316 (gs_load): Use x_check_image_size.
15318 * gtkutil.c: Omit integer casts.
15319 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15320 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15322 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15324 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15325 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15326 would wrongly return t on a 64-bit host.
15328 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15329 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15330 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15331 and therefore cause GCC to emit a bogus diagnostic in some cases.
15333 * image.c: Integer signedness and overflow and related fixes.
15334 This is not an exhaustive set of fixes, but it's time to
15335 record what I've got.
15336 (lookup_pixel_color, check_image_size): Remove redundant decls.
15337 (check_image_size): Don't assume that arbitrary EMACS_INT values
15338 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15339 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15340 (tiff_load, imagemagick_load_image):
15341 Check for overflow in size calculations.
15342 (x_create_x_image_and_pixmap): Remove unnecessary test for
15343 xmalloc returning NULL; that can't happen.
15344 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15345 (xpm_color_bucket): Use better integer hashing function.
15346 (xpm_cache_color): Don't possibly over-allocate memory.
15347 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15348 (gif_memory_source):
15349 Use ptrdiff_t, not int or size_t, to record sizes.
15350 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15351 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15352 either works, as we prefer signed integers.
15353 (tiff_read_from_memory, tiff_write_from_memory):
15354 Return tsize_t, not size_t, since that's what the TIFF API wants.
15355 (tiff_read_from_memory): Don't fail simply because the read would
15356 go past EOF; instead, return a short read.
15357 (tiff_load): Omit no-longer-needed casts.
15358 (Fimagemagick_types): Don't assume size fits into 'int'.
15360 Improve hashing quality when configured --with-wide-int.
15361 * fns.c (hash_string): New function, taken from sxhash_string.
15362 Do not discard information about ASCII character case; this
15363 discarding is no longer needed.
15364 (sxhash-string): Use it. Change sig to match it. Caller changed.
15365 * lisp.h: Declare it.
15366 * lread.c (hash_string): Remove, since we now use fns.c's version.
15367 The fns.c version returns a wider integer if --with-wide-int is
15368 specified, so this should help the quality of the hashing a bit.
15370 * emacs.c: Integer overflow minor fix.
15371 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15372 Define only if GNU_LINUX.
15373 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15375 * dispnew.c: Integer signedness and overflow fixes.
15376 Remove unnecessary forward decls, that were a maintenance hassle.
15377 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15379 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15380 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15381 (prepare_desired_row, line_draw_cost):
15382 Use int, not unsigned, where either works.
15383 (save_current_matrix, restore_current_matrix):
15384 Use ptrdiff_t, not size_t, where either works.
15385 (init_display): Check for overflow more accurately, and without
15386 relying on undefined behavior.
15388 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15389 Remove, replacing with the new symbols in lisp.h. All uses changed.
15390 * fileio.c (make_temp_name):
15391 * filelock.c (lock_file_1, lock_file):
15392 * xdisp.c (message_dolog):
15393 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15394 Use pMd etc. instead.
15395 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15396 replacing the pWIDE etc. symbols removed from editfns.c.
15398 * keyboard.h (num_input_events): Now uintmax_t.
15399 This is (very slightly) less likely to mess up due to wraparound.
15402 * buffer.c: Integer signedness fixes.
15403 (alloc_buffer_text, enlarge_buffer_text):
15404 Use ptrdiff_t rather than size_t when either will do, as we prefer
15407 * alloc.c: Integer signedness and overflow fixes.
15408 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15409 (__malloc_size_t): Default to size_t, not to int.
15410 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15411 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15412 Prefer ptrdiff_t to size_t when either would do, as we prefer
15414 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15415 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15416 Now const. Initialize with values that are in range even if char
15418 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15419 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15420 These functions do the right thing with sizes > 2**32.
15421 (check_depth): Now ptrdiff_t, not int.
15422 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15423 Adjust to new way of storing sizes. Check for size overflow bugs
15425 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15426 slightly wrong anyway, as it missed one instance of
15427 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15428 (refill_memory_reserve): Omit needless cast to size_t.
15429 (mark_object_loop_halt): Mark as externally visible.
15431 * xselect.c: Integer signedness and overflow fixes.
15432 (Fx_register_dnd_atom, x_handle_dnd_message):
15433 Use ptrdiff_t, not size_t, since we prefer signed.
15434 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15435 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15436 x_dnd_atoms_size and x_dnd_atoms_length.
15438 * doprnt.c: Prefer signed to unsigned when either works.
15440 * doprnt.c (doprnt):
15442 * xdisp.c (vmessage):
15443 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15444 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15445 prefer signed arithmetic to avoid comparison confusion.
15446 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15447 but is a bit tricky.
15449 Assume freestanding C89 headers, string.h, stdlib.h.
15450 * data.c, doprnt.c, floatfns.c, print.c:
15451 Include float.h unconditionally.
15452 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15453 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15454 * regex.c: Likewise for stddef.h, string.h.
15455 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15456 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15457 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15458 (STDC_HEADERS): Remove obsolete defines.
15459 * sysdep.c: Include limits.h unconditionally.
15461 Assume support for memcmp, memcpy, memmove, memset.
15462 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15463 * regex.c (memcmp, memcpy):
15464 Remove; we assume C89 now.
15466 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15467 (__malloc_safe_bcopy): Remove; no longer needed.
15469 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15470 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15471 well either way, and we prefer signed to unsigned.
15473 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15475 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15476 closes the connection while we're reading (bug#9182).
15478 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15480 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15481 are specified (Bug#9168).
15483 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15485 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15486 Found by GCC static checking and --with-wide-int on a 32-bit host.
15488 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15490 * xdisp.c (compute_display_string_pos): Fix logic of caching
15491 previous display string position. Initialize cached_prev_pos to
15492 -1. Fixes slow-down at the beginning of a buffer.
15494 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15496 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15497 for attrs[LFACE_FONTSET_INDEX].
15499 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15501 * xml.c (parse_region): Remove unused local
15502 that was recently introduced.
15504 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15506 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15507 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15509 * xdisp.c (move_it_in_display_line_to): Record the best matching
15510 position for TO_CHARPOS while scanning the line, and restore it on
15511 exit if none of the characters scanned was an exact match.
15512 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15513 when exact match is impossible due to invisible text, and the
15514 lines are truncated.
15516 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15518 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15521 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15523 Fix a significant slow-down of cursor motion with C-n, C-p,
15524 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15525 auto-repeat under bidi redisplay in fontified buffers.
15526 * xdisp.c (compute_stop_pos_backwards): New function.
15527 (next_element_from_buffer): Call compute_stop_pos_backwards to
15528 find a suitable prev_stop when we find ourselves before
15530 (reseat): Don't look for prev_stop, as that could mean a very long
15532 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15533 <cached_disp_overlay_modiff>: Cache for last found display string
15535 (compute_display_string_pos): Return the cached position if asked
15536 about the same buffer in the same area of character positions, and
15537 the buffer wasn't changed since the time the display string
15538 position was cached.
15540 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15542 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15543 is an integer, which is important for empty lines. (Bug#9149)
15545 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15547 * frame.c (Fmodify_frame_parameters): In tty case, update the
15548 default face if necessary (Bug#4238).
15550 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15552 * editfns.c (Fstring_to_char): No need to explain what a character
15553 is in the docstring (Bug#6576).
15555 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15557 * xml.c (parse_region): Make sure we always return a tree.
15559 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15561 * xml.c (parse_region): If a document contains only comments,
15564 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15566 * xml.c (make_dom): Return comments, too.
15568 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15571 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15572 and the surrounding thread.
15573 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15574 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15575 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15577 * s/openbsd.h (BROKEN_SIGIO): Define.
15578 * unexelf.c (unexec) [__OpenBSD__]:
15579 Don't update the .mdebug section of the Alpha COFF symbol table.
15581 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15583 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15586 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15588 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15589 This fixes some race conditions on the permissions of any newly
15592 * alloc.c (valid_pointer_p): Use pipe, not open.
15593 This fixes some permissions issues when debugging.
15595 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15596 If fchown fails to set both uid and gid, try to set just gid,
15597 as that is sometimes allowed. Adjust the file's mode to eliminate
15598 setuid or setgid bits that are inappropriate if fchown fails.
15600 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15602 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15603 to compare Lisp_Objects.
15604 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15605 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15606 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15608 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15610 * lread.c (read_integer): Unread even EOF character.
15611 (read1): Likewise. Properly record start position of symbol.
15613 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15614 symbol character follows.
15616 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15618 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15619 This works around a problem with the previous change to Fcopy_file.
15620 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15621 and without this change, GCC might complain about discarding
15622 fchown's return value.
15624 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15626 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

15720 the iterator is before prev_stop.
15721 (init_iterator): Initialize bidi_p from the default value of

15768 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15769 (push_display_prop): xassert that we are iterating a buffer.

16240 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16241 subseconds part to the entropy, as that's a bit more random.
16242 Prefer signed to unsigned, since the signedness doesn't matter and
16243 in general we prefer signed. When given a limit, use a
16244 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16245 latter isn't right if USE_2_TAGS_FOR_INTS.
16246 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16247 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16290 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16291 Also (re)move comments that are misplaced or no longer relevant.

16393 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16394 signed bit field, as this assumption is not portable and it makes
16395 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16396 "char debug_on_exit : 1" as this is not portable either; instead,
16397 use the portable "unsigned int debug_on_exit : 1". Remove unused
16398 member evalargs. Remove obsolete comments about cc bombing out.

16562 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16564 Integer and buffer overflow fixes (Bug#8873).
16566 * print.c (printchar, strout): Check for string overflow.
16567 (PRINTPREPARE, printchar, strout):
16568 Don't set size unless allocation succeeds.
16570 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16571 for sizes. Check for string overflow more accurately.
16572 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16574 * macros.c: Integer and buffer overflow fixes.
16575 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16576 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
16577 Use ptrdiff_t, not int, for sizes.
16578 Don't increment bufsize until after realloc succeeds.
16579 Check for size-calculation overflow.
16580 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16582 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16584 * lread.c: Integer overflow fixes.
16585 (read_integer): Radix is now EMACS_INT, not int,
16586 to improve quality of diagnostics for out-of-range radices.
16587 Calculate buffer size correctly for out-of-range radices.
16588 (read1): Check for integer overflow in radices, and in
16589 read-circle numbers.
16590 (read_escape): Avoid int overflow.
16591 (Fload, openp, read_buffer_size, read1)
16592 (substitute_object_recurse, read_vector, read_list, map_obarray):
16593 Use ptrdiff_t, not int, for sizes.

16608 2011-06-22 Leo Liu <sdl.web@gmail.com>
16610 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16611 Move to minibuffer.el.
16613 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16615 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16616 The following patches are for when GLYPH_DEBUG && !XASSERT.
16617 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16618 * dispnew.c (flush_stdout):
16619 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16620 Mark as externally visible.
16621 * dispnew.c (check_window_matrix_pointers): Now static.
16622 * dispnew.c (window_to_frame_vpos):
16623 * xfns.c (unwind_create_frame):
16624 * xterm.c (x_check_font): Remove unused local.
16625 * scroll.c (CHECK_BOUNDS):
16626 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16627 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16628 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16629 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16630 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16632 (debug_method_add): Use va_list and vsprintf rather than relying
16633 on undefined behavior with wrong number of arguments.
16634 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16635 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16636 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16637 since we're not interested in debugging glyphs with old libraries.
16638 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16639 GCC 4.6.0's static checking.
16641 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16643 Integer overflow and signedness fixes (Bug#8873).

16652 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16653 (x_create_bitmap_from_xpm_data):
16654 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16655 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16657 * xfaces.c (load_pixmap):
16658 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16659 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16660 (.bitmaps_last, struct x_output.icon_bitmap):
16661 Use ptrdiff_t, not int, for bitmap indexes.
16662 (x_allocate_bitmap_record): Check for size overflow.
16663 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16665 Use ptrdiff_t, not int, for overlay counts.
16666 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16667 * editfns.c (overlays_around, get_pos_property):
16668 * textprop.c (get_char_property_and_overlay):
16669 * xdisp.c (next_overlay_change, note_mouse_highlight):
16670 * xfaces.c (face_at_buffer_position):
16671 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16672 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16673 (Fnext_overlay_change, Fprevious_overlay_change)
16674 (mouse_face_overlay_overlaps, Foverlays_in):
16675 Use ptrdiff_t, not int, for sizes.
16676 (overlays_at, overlays_in): Check for size-calculation overflow.
16678 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16680 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16681 (x_session_initialize): Do not assume string length fits in int.
16683 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16684 This is unlikely, but can occur if DPI is outlandish.
16686 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16687 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16689 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16690 * xrdb.c (magic_file_p, search_magic_path):
16691 Omit last arg SUFFIX; it was always 0. All callers changed.
16692 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16694 * xfont.c (xfont_match): Avoid need for strlen.
16696 * xfns.c: Don't assume strlen fits in int.
16697 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16699 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16700 not unsigned long, as we prefer signed integers. All callers changed.
16701 Detect integer overflow in repeat count.
16702 (message_dolog): Don't assume print length fits in 39 bytes.
16703 (display_mode_element): Don't assume strlen fits in int.
16705 * termcap.c: Don't assume sizes fit in int and never overflow.
16706 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16707 (gobble_line): Check for size-calculation overflow.
16709 * minibuf.c (Fread_buffer):
16710 * lread.c (intern, intern_c_string):
16711 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16712 Don't assume string length fits in int.
16714 * keyboard.c (parse_tool_bar_item):
16715 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16717 * font.c: Don't assume string length fits in int.
16718 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16719 Use ptrdiff_t, not int.
16720 (font_intern_prop): Don't assume string length fits in int.
16721 Don't assume integer property fits in fixnum.
16722 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16724 * filelock.c: Fix some buffer overrun and integer overflow issues.
16725 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16726 Reformulate so as not to need the command string.
16727 Invoke gzip -cd rather than gunzip, as it's more portable.
16728 (lock_info_type, lock_file_1, lock_file):
16729 Don't assume pid_t and time_t fit in unsigned long.
16730 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16731 (current_lock_owner): Prefer signed type for sizes.
16732 Use memcpy, not strncpy, where memcpy is what is really wanted.
16733 Don't assume (via atoi) that time_t and pid_t fit in int.
16734 Check for time_t and/or pid_t out of range, e.g., via a network share.
16735 Don't alloca where an auto var works fine.
16737 * fileio.c: Fix some integer overflow issues.
16738 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16739 Don't assume string length fits in int.
16740 (directory_file_name): Don't assume string length fits in long.
16741 (make_temp_name): Don't assume pid fits in int, or that its print
16742 length is less than 20.
16744 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16746 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16748 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16750 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16751 We prefer signed integers, even for size calculations.
16753 * emacs.c: Don't assume string length fits in 'int'.
16754 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16755 (main): Don't invoke strlen when not needed.
16757 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16758 (XD_DEBUG_MESSAGE): Don't waste a byte.
16760 * callproc.c (getenv_internal_1, getenv_internal)
16761 (Fgetenv_internal):
16762 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16764 * lread.c (invalid_syntax): Omit length argument.
16765 All uses changed. This doesn't fix a bug, but it simplifies the
16766 code away from its former Hollerith-constant appearance, and it's
16767 one less 'int' to worry about when looking at integer-overflow issues.
16768 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16770 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16771 This didn't break anything, but it didn't help either.
16772 It's confusing to put a bogus integer in a place where the actual
16773 value does not matter.
16774 (LIST_END_P): Remove unused macro and its bogus comment.
16775 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16777 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16778 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16780 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16781 We prefer signed types, and the value cannot exceed the EMACS_INT
16782 range anyway (because otherwise the length would not be representable).
16783 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16784 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16785 This avoids a GCC warning when WIDE_EMACS_INT.
16787 * indent.c (sane_tab_width): New function.
16788 (current_column, scan_for_column, Findent_to, position_indentation)
16789 (compute_motion): Use it. This is just for clarity.
16790 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16792 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16794 * lisp.h (lint_assume): New macro.
16795 * composite.c (composition_gstring_put_cache):
16796 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16798 * editfns.c, insdel.c:
16799 Omit unnecessary forward decls, to simplify future changes.
16801 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16803 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16805 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16806 Use much-faster test for byte-length change.
16807 Don't assume string byte-length fits in 'int'.
16808 Check that character arg fits in 'int'.
16809 (mapcar1): Declare byte as byte, for clarity.
16811 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16813 * fns.c (concat): Catch string overflow earlier.
16814 Do not rely on integer wraparound.
16816 * dispextern.h (struct it.overlay_strings_charpos)
16817 (struct it.selective): Now EMACS_INT, not int.
16818 * xdisp.c (forward_to_next_line_start)
16819 (back_to_previous_visible_line_start)
16820 (reseat_at_next_visible_line_start, next_element_from_buffer):
16821 Don't arbitrarily truncate the value of 'selective' to int.
16823 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16825 * composite.c: Don't truncate sizes to 'int'.
16826 (composition_gstring_p, composition_reseat_it)
16827 (composition_adjust_point): Use EMACS_INT, not int.
16828 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16829 not EMACS_UINT, for indexes.
16831 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16833 * buffer.c: Include <verify.h>.
16834 (struct sortvec.priority, struct sortstr.priority):
16835 Now EMACS_INT, not int.
16836 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16837 (struct sortstr.size, record_overlay_string)
16838 (struct sortstrlist.size, struct sortlist.used):
16839 Don't truncate size to int.
16840 (record_overlay_string): Check for size-calculation overflow.
16841 (init_buffer_once): Check at compile-time, not run-time.
16843 2011-06-22 Jim Meyering <meyering@redhat.com>
16845 Don't leak an XBM-image-sized buffer
16846 * image.c (xbm_load): Free the image buffer after using it.
16848 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16851 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16852 that Sun C diagnosed.
16853 * fns.c (secure_hash): Fix pointer signedness issue.
16854 * intervals.c (static_offset_intervals): New function.
16855 (offset_intervals): Use it.
16857 2011-06-21 Leo Liu <sdl.web@gmail.com>
16860 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16863 * fns.c (secure_hash): Rename from crypto_hash_function and change
16864 the first arg to accept symbols.
16865 (Fsecure_hash): New primitive.
16866 (syms_of_fns): New symbols.
16868 2011-06-20 Deniz Dogan <deniz@dogan.se>
16870 * process.c (Fset_process_buffer): Clarify return value in
16873 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16875 * dispnew.c (add_window_display_history): Use BVAR.
16877 * xdisp.c (debug_method_add): Use BVAR.
16878 (check_window_end, dump_glyph_matrix, dump_glyph)
16879 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16881 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16884 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16885 check till after the cache is created in init_frame_faces.
16887 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16889 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16891 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16893 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16894 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16895 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16897 Improve buffer-overflow checking (Bug#8873).
16898 * fileio.c (Finsert_file_contents):
16899 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16900 Remove the old (too-loose) buffer overflow checks.
16901 They weren't needed, since make_gap checks for buffer overflow.
16902 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16903 The old code merely checked for Emacs fixnum overflow, and relied
16904 on undefined (wraparound) behavior. The new code avoids undefined
16905 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16907 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16908 Tune. Don't use wider integers than needed. Don't use alloca.
16909 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16911 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16913 * insdel.c, lisp.h (buffer_overflow): New function.
16914 (insert_from_buffer_1, replace_range, replace_range_2):
16915 * insdel.c (make_gap_larger):
16916 * editfns.c (Finsert_char):
16917 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16919 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16921 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16923 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16925 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16926 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16928 * fileio.c: Don't assume EMACS_INT fits in off_t.
16929 (emacs_lseek): New static function.
16930 (Finsert_file_contents, Fwrite_region): Use it.
16931 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16933 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16935 * fns.c: Don't overflow int when computing a list length.
16936 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16937 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16938 truncation on 64-bit hosts. Check for QUIT every
16939 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16940 faster and is responsive enough.
16941 (Flength): Report an error instead of overflowing an integer.
16942 (Fsafe_length): Return a float if the value is not representable
16943 as a fixnum. This shouldn't happen except in contrived situations.
16944 (Fnthcdr, Fsort): Don't assume list length fits in int.
16945 (Fcopy_sequence): Don't assume vector length fits in int.
16947 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16948 (header_size, word_size): New constants.
16949 (allocate_vectorlike): Don't check size overflow here.
16950 (allocate_vector): Check it here instead, since this is the only
16951 caller of allocate_vectorlike that could cause overflow.
16952 Check that the new vector's length is representable as a fixnum.
16954 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16955 The previous code was bogus. For example, next_almost_prime (32)
16956 returned 39, which is undesirable as it is a multiple of 3; and
16957 next_almost_prime (24) returned 25, which is a multiple of 5 so
16958 why was the code bothering to check for multiples of 7?
16960 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16962 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16964 Variadic C functions now count arguments with ptrdiff_t.
16965 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16966 Back then I didn't know that the Emacs coding style prefers signed int.
16967 Also, in the meantime I found a few more instances where arguments
16968 were being counted with int, which may truncate counts on 64-bit
16969 machines, or EMACS_INT, which may be unnecessarily wide.
16970 * lisp.h (struct Lisp_Subr.function.aMANY)
16971 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16972 Arg counts are now ptrdiff_t, not size_t.
16973 All variadic functions and their callers changed accordingly.
16974 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16975 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16976 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16977 * callint.c (Fcall_interactively): Check arg count for overflow,
16978 to avoid potential buffer overrun. Use signed char, not 'int',
16979 for 'varies' array, so that we needn't bother to check its size
16980 calculation for overflow.
16981 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16982 * eval.c (apply_lambda):
16983 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16984 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16985 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16987 * callint.c (Fcall_interactively): Don't use index var as event count.
16989 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16990 * mem-limits.h (SIZE): Remove; no longer used.
16992 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16994 Remove unnecessary casts.
16995 * xterm.c (x_term_init):
16996 * xfns.c (x_set_border_pixel):
16997 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16998 These aren't needed now that we assume ANSI C.
17000 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17001 It's more likely to cause problems (due to unsigned overflow)
17004 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17006 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17008 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17010 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17012 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17014 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17016 GLYPH_CODE_FACE returns EMACS_INT, not int.
17017 * dispextern.h (merge_faces):
17018 * xfaces.c (merge_faces):
17019 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17020 Don't assume EMACS_INT fits in int.
17022 * character.h (CHAR_VALID_P): Remove unused parameter.
17023 * fontset.c, lisp.h, xdisp.c: All uses changed.
17025 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17027 * fns.c (concat): Minor tuning based on overflow analysis.
17028 This doesn't fix any bugs. Use int to hold character, instead
17029 of constantly refetching from Emacs object. Use XFASTINT, not
17030 XINT, for value known to be a character. Don't bother comparing
17031 a single byte to 0400, as it's always less.
17033 * floatfns.c (Fexpt):
17034 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17036 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17039 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17041 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17042 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17043 incorrectly succeed when S was a string, because 4294967386 was
17044 truncated before it was used.
17046 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17047 Otherwise, an out-of-range integer could cause undefined behavior
17050 * composite.c: Use int, not EMACS_INT, for characters.
17051 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17052 EMACS_INT, for values that are known to be in character range.
17053 This doesn't fix any bugs but is the usual style inside Emacs and
17054 may generate better code on 32-bit machines.
17056 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17057 This is for reasons similar to the recent CHAR_STRING fix.
17058 * charset.c (Fencode_char): Check that character arg is actually
17059 a character. Pass an int to ENCODE_CHAR.
17060 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17061 wider than 'int', as a compile-time check to prevent future regressions
17064 * character.c (char_string): Remove unnecessary casts.
17066 Make sure a 64-bit char is never passed to CHAR_STRING.
17067 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17068 by silently ignoring the top 32 bits, allowing some values
17069 that were far too large to be valid characters.
17070 * character.h: Include <verify.h>.
17071 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17072 arguments are no wider than unsigned, as a compile-time check
17073 to prevent future regressions in this area.
17075 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17076 (Fsubst_char_in_region):
17078 * xdisp.c (decode_mode_spec_coding):
17079 Adjust to CHAR_STRING's new requirement.
17080 * editfns.c (Finsert_char, Fsubst_char_in_region):
17081 * fns.c (concat): Check that character args are actually
17082 characters. Without this test, these functions did the wrong
17083 thing with wildly out-of-range values on 64-bit hosts.
17085 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17086 These casts should not be needed on 32-bit hosts, either.
17087 * keyboard.c (read_char):
17088 * lread.c (Fload): Remove casts to unsigned.
17090 * lisp.h (UNSIGNED_CMP): New macro.
17091 This fixes comparison bugs on 64-bit hosts.
17092 (ASCII_CHAR_P): Use it.
17093 * casefiddle.c (casify_object):
17094 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17095 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17096 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17097 * dispextern.h (FACE_FROM_ID):
17098 * keyboard.c (read_char): Use UNSIGNED_CMP.
17100 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17101 not to EMACS_INT, to avoid GCC warning.
17103 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17105 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17106 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17107 isn't needed on 32-bit machines.
17109 * buffer.c (Fgenerate_new_buffer_name):
17110 Use EMACS_INT for count, not int.
17111 (advance_to_char_boundary): Return EMACS_INT, not int.
17113 * data.c (Qcompiled_function): Now static.
17115 * window.c (window_body_lines): Now static.
17117 * image.c (gif_load): Rename local to avoid shadowing.
17119 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17120 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17121 * alloc.c (make_save_value): Integer argument is now of type
17122 ptrdiff_t, not int.
17123 (mark_object): Use ptrdiff_t, not int.
17124 * lisp.h (pD): New macro.
17125 * print.c (print_object): Use it.
17127 * alloc.c: Use EMACS_INT, not int, to count objects.
17128 (total_conses, total_markers, total_symbols, total_vector_size)
17129 (total_free_conses, total_free_markers, total_free_symbols)
17130 (total_free_floats, total_floats, total_free_intervals)
17131 (total_intervals, total_strings, total_free_strings):
17132 Now EMACS_INT, not int. All uses changed.
17133 (Fgarbage_collect): Compute overall total using a double, so that
17134 integer overflow is less likely to be a problem. Check for overflow
17135 when converting back to an integer.
17136 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17137 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17138 These were 'int' variables that could overflow on 64-bit hosts;
17139 they were never used, so remove them instead of repairing them.
17140 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17141 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17142 Previously, this ceilinged at INT_MAX, but that doesn't work on
17144 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17146 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17147 (allocate_vectorlike): Check for ptrdiff_t overflow.
17148 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17149 when a (possibly-narrower) signed value would do just as well.
17150 We prefer using signed arithmetic, to avoid comparison confusion.
17152 * alloc.c: Catch some string size overflows that we were missing.
17153 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17154 for convenience in STRING_BYTES_MAX.
17155 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17156 The definition here is exact; the one in lisp.h was approximate.
17157 (allocate_string_data): Check for string overflow. This catches
17158 some instances we weren't catching before. Also, it catches
17159 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17160 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17161 and ptrdiff_t and EMACS_INT are both 64 bits.
17163 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17164 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17165 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17167 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17169 * alloc.c (Fmake_string): Check for out-of-range init.
17171 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17173 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17175 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17177 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17178 xg_get_default_scrollbar_width.
17180 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17181 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17182 (style_changed_cb): Call update_theme_scrollbar_width and call
17183 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17184 all frames (Bug#8505).
17185 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17186 Call gtk_window_set_resizable if HAVE_GTK3.
17187 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17188 and height if HAVE_GTK3 (Bug#8505).
17189 (scroll_bar_width_for_theme): New variable.
17190 (update_theme_scrollbar_width): New function.
17191 (xg_get_default_scrollbar_width): Move code to
17192 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17193 (xg_initialize): Call update_theme_scrollbar_width.
17195 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17197 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17199 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17201 * frame.c (make_frame): Call other_buffer_safely instead of
17204 * window.c (temp_output_buffer_show): Call display_buffer with
17205 second argument Vtemp_buffer_show_specifiers and reset latter
17206 immediately after the call.
17207 (Vtemp_buffer_show_specifiers): New variable.
17208 (auto_window_vscroll_p, next_screen_context_lines)
17209 (Vscroll_preserve_screen_position): Remove leading asterisks from
17212 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
17214 Fix minor problems found by GCC 4.6.0 static checking.
17215 * buffer.c (Qclone_number): Remove for now, as it's unused.
17216 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
17217 (record_buffer): Remove unused local.
17218 * frame.c (other_visible_frames, frame_buffer_list): Now static.
17219 (set_frame_buffer_list): Remove; unused.
17220 * frame.h (other_visible_frames): Remove decl.
17221 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
17222 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
17223 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
17225 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
17226 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
17227 Define only if HAVE_GPM.
17228 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
17229 (update_hints_inhibit): Remove; never set. All uses removed.
17230 * widgetprv.h (emacsFrameClassRec): Remove decl.
17231 * window.c (delete_deletable_window): Now returns void, since it
17232 wasn't returning anything.
17233 (compare_window_configurations): Remove unused locals.
17234 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
17235 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
17236 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
17237 the same widths as pointers. This follows up on the 2011-05-06 patch.
17238 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
17239 * xterm.h: Likewise.
17240 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

17245 (LISP_H): Add lib/intprops.h.
17247 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
17249 * image.c (gif_load): Add animation frame delay to the metadata.
17250 (syms_of_image): Use DEFSYM. New symbol `delay'.
17252 2011-06-11 Martin Rudalics <rudalics@gmx.at>
17254 * window.c (delete_deletable_window): Re-add.
17255 (Fset_window_configuration): Rewrite to handle dead buffers and
17256 consequently deletable windows.
17257 (window_tree, Fwindow_tree): Remove. Supply functionality in
17259 (compare_window_configurations): Simplify code.
17261 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
17263 * image.c (imagemagick_load_image): Fix type mismatch.
17264 (Fimagemagick_types): Likewise.
17266 * window.h (replace_buffer_in_windows): Declare.
17268 2011-06-11 Martin Rudalics <rudalics@gmx.at>
17270 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
17271 Qclone_number. Remove external declaration of Qdelete_window.
17272 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
17274 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
17275 Run Qbuffer_list_update_hook if allowed.
17276 (Fother_buffer): Rewrite doc-string. Major rewrite for new
17277 buffer list implementation.
17278 (other_buffer_safely): New function.
17279 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
17280 calls to replace_buffer_in_windows and
17281 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
17283 (record_buffer): Inhibit quitting and rewrite using quittable
17284 functions. Run Qbuffer_list_update_hook if allowed.
17285 (Frecord_buffer, Funrecord_buffer): New functions.
17286 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
17287 Move switch-to-buffer to window.el.
17288 (bury-buffer): Move to window.el.
17289 (Vbuffer_list_update_hook): New variable.
17291 * lisp.h (other_buffer_safely): Add prototype in buffer.c
17294 * window.h (resize_frame_windows): Move up in code.
17295 (Fwindow_frame): Remove EXFUN.
17296 (replace_buffer_in_all_windows): Remove prototype.
17297 (replace_buffer_in_windows_safely): Add prototype.
17299 * window.c: Declare Qdelete_window static again. Move down
17300 declaration of select_count.
17301 (Fnext_window, Fprevious_window): Rewrite doc-strings.
17302 (Fother_window): Move to window.el.
17303 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
17304 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
17305 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
17307 (replace_buffer_in_windows): Implement by calling
17308 Qreplace_buffer_in_windows.
17309 (replace_buffer_in_all_windows): Remove with some functionality
17310 moved into replace_buffer_in_windows_safely.
17311 (replace_buffer_in_windows_safely): New function.
17312 (select_window_norecord, select_frame_norecord): Move in front
17313 of run_window_configuration_change_hook. Remove now obsolete
17315 (Fset_window_buffer): Rewrite doc-string.
17316 Call Qrecord_window_buffer.
17317 (keys_of_window): Move binding for other-window to window.el.
17319 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
17321 * dispextern.h (struct image): Replace data member, whose int_val
17322 and ptr_val fields were not used by anything, with a single
17325 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
17326 (gif_clear_image, gif_load, imagemagick_load_image)
17327 (gs_clear_image, gs_load): Callers changed.

17754 were just reseat()'ed to a new position.
17756 * xdisp.c (set_cursor_from_row): Set start and stop points
17757 according to the row's direction when priming the loop that looks

17760 (display_prop_intangible_p): Reimplement to call
17761 handle_display_spec instead of single_display_spec_intangible_p.

17766 lists with the argument STRING its top-level element.
17767 (display_prop_string_p): Fix the condition for processing a

17772 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17773 value of a `display' property is a "replacing spec".
17774 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17775 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17776 the display property, but just return a value indicating whether
17777 the display property will replace the characters it covers.
17778 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17779 frame_window_p members of struct bidi_it.

17803 All callers changed. (Bug#8762)
17805 * gnutls.c: Use Emacs's memory allocators.
17806 Without this change, the gnutls library would invoke malloc etc.
17807 directly, which causes problems on non-SYNC_INPUT hosts, and which
17808 runs afoul of improving memory_full behavior. (Bug#8761)
17809 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17810 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17811 xfree instead of the default malloc, realloc, free.
17812 (Fgnutls_boot): No need to check for memory allocation failure,
17813 since xmalloc does that for us.

17833 * lisp.h (struct Lisp_Hash_Table):
17834 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
17835 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17836 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17837 * alloc.c (allocate_vectorlike):
17838 Check for overflow in vector size calculations.
17839 * ccl.c (ccl_driver):
17840 Check for overflow when converting EMACS_INT to int.
17841 * fns.c, image.c: Remove unnecessary static decls that would otherwise
17842 need to be updated by these changes.
17843 * fns.c (make_hash_table, maybe_resize_hash_table):
17844 Check for integer overflow with large hash tables.
17845 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17846 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17847 (SXHASH_REDUCE): New macro.
17848 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17849 Use it instead of discarding useful hash info with large hash values.
17850 (sxhash_float): New function.
17851 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17852 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17853 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17854 Rewrite to use FIXNUM_BITS, as this simplifies things.
17855 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17856 Adjust signatures to match updated version of code.
17857 (consing_since_gc): Now EMACS_INT, since a single hash table can
17858 use more than INT_MAX bytes.
17860 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17862 Make it possible to build with GCC-4.6+ -O2 -flto.

17873 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17874 Update dependencies.
17876 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17878 * data.c (init_data): Remove code for UTS, this system is not
17881 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17883 Don't force ./temacs to start in terminal mode.
17885 * frame.c (make_initial_frame): Initialize faces in all cases, not
17886 only when CANNOT_DUMP is defined.
17887 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17889 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17891 * dispnew.c (add_window_display_history): Use const for the string
17892 pointer. Remove declaration, not needed.
17894 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17896 Use 'inline', not 'INLINE'.
17897 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17898 * alloc.c, fontset.c (INLINE): Remove.
17899 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17900 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17901 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17902 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17903 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17905 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17907 Make it possible to run ./temacs.
17909 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17910 syms_of_callproc does the same thing. Remove test for
17911 "initialized", do it in the caller.
17912 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17914 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17916 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17917 (read_minibuf): Use get_minibuffer.
17918 (syms_of_minibuf): Use DEFSYM.
17919 (Qmetadata): New var.
17920 * data.c (Qbuffer): Don't make it static.
17921 (syms_of_data): Use DEFSYM.
17923 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17925 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17926 (CCL_CODE_MIN): New macro.
17928 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17930 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17932 * eval.c (Qdebug): Now static.
17933 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17934 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17935 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17937 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17939 * image.c: Various fixes to ImageMagick code comments.
17940 (Fimagemagick_types): Doc fix.
17942 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17944 Minor fixes prompted by GCC 4.6.0 warnings.
17946 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17948 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17949 (x_clipboard_manager_save_all): Move extern decl to ...
17950 * xterm.h: ... here, so that it can be checked for consistency.
17952 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17954 * xselect.c (x_clipboard_manager_save_frame)
17955 (x_clipboard_manager_save_all): New functions.
17956 (Fx_clipboard_manager_save): Lisp function deleted.
17958 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17959 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17961 * xterm.h: Update prototype.
17963 2011-05-28 William Xu <william.xwl@gmail.com>
17965 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17966 exiting (Bug#8239).
17968 2011-05-28 Jim Meyering <meyering@redhat.com>
17970 Avoid a sign-extension bug in crypto_hash_function.
17971 * fns.c (to_uchar): Define.
17972 (crypto_hash_function): Use it to convert some newly-signed
17973 variables to unsigned, to avoid sign-extension bugs. For example,
17974 without this change, (md5 "truc") would evaluate to
17975 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17976 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17977 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17979 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17981 Integer overflow fixes.
17983 * dbusbind.c: Serial number integer overflow fixes.
17984 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17985 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17986 to hold a serial number that is too large for a fixnum.
17987 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17988 Check for serial numbers out of range. Decode any serial number
17989 that was so large that it became a float. (Bug#8722)
17991 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17992 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17993 Use XFASTINT rather than XUINT when numbers are nonnegative.
17994 (xd_append_arg, Fdbus_method_return_internal):
17995 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17996 arguments, check that Lisp number is nonnegative, rather than
17997 silently wrapping negative numbers around. (Bug#8722)
17998 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18001 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18003 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18005 ccl: Add integer overflow checks.
18006 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18007 (IN_INT_RANGE): New macros.
18008 (ccl_driver): Use them to check for integer overflow when
18009 decoding a CCL program. Many of the new checks are whether XINT (x)
18010 fits in int; it doesn't always, on 64-bit hosts. The new version
18011 doesn't catch all possible integer overflows, but it's an
18012 improvement. (Bug#8719)
18014 * alloc.c (make_event_array): Use XINT, not XUINT.
18015 There's no need for unsigned here.
18017 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18018 This follows up to the 2011-05-06 change that substituted uintptr_t
18019 for EMACS_INT. This case wasn't caught back then.
18021 Rework Fformat to avoid integer overflow issues.
18022 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18023 now (part of C89). Include <verify.h>.
18024 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18025 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18026 (Fformat): Avoid the prepass trying to compute sizes; it was only
18027 approximate and thus did not catch overflow reliably. Instead, walk
18028 through the format just once, formatting and computing sizes as we go,
18029 checking for integer overflow at every step, and allocating a larger
18030 buffer as needed. Keep track separately whether the format is
18031 multibyte. Keep only the most-recently calculated precision, rather
18032 than them all. Record whether each argument has been converted to
18033 string. Use EMACS_INT, not int, for byte and char and arg counts.
18034 Support field widths and precisions larger than INT_MAX. Avoid
18035 sprintf's undefined behavior with conversion specifications such as %#d
18036 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18037 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18038 formatting out-of-range floating point numbers with int
18039 formats. (Bug#8668)
18041 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18043 * data.c: Avoid integer truncation in expressions involving floats.
18044 * data.c: Include <intprops.h>.
18045 (arith_driver): When there's an integer overflow in an expression
18046 involving floating point, convert the integers to floating point
18047 so that the resulting value does not suffer from catastrophic
18048 integer truncation. For example, on a 64-bit host (* 4
18049 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18050 Do not rely on undefined behavior after integer overflow.
18052 merge count_size_as_multibyte, parse_str_to_multibyte
18053 * character.c, character.h (count_size_as_multibyte):
18054 Rename from parse_str_to_multibyte; all uses changed.
18055 Check for integer overflow.
18056 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18057 since it's now a duplicate of the other. This is more of
18058 a character than a buffer op, so better that it's in character.c.
18059 * fns.c, print.c: Adjust to above changes.
18061 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18063 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18065 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18067 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18068 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18069 (x_clipboard_manager_save): Now static.
18070 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18072 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18073 (crypto_hash_function): Now static.
18074 Fix pointer signedness problems. Avoid unnecessary initializations.
18076 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18078 * termhooks.h (Vselection_alist): Make it terminal-local.
18080 * terminal.c (create_terminal): Initialize it.
18082 * xselect.c: Support for clipboard managers.
18083 (Vselection_alist): Move to termhooks.h as terminal-local var.
18084 (LOCAL_SELECTION): New macro.
18085 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18086 (symbol_to_x_atom): Remove gratuitous arg.
18087 (x_handle_selection_request, lisp_data_to_selection_data)
18088 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18089 (x_own_selection, x_get_local_selection, x_convert_selection):
18090 New arg, specifying work frame. Use terminal-local Vselection_alist.
18091 (some_frame_on_display): Delete unused function.
18092 (Fx_own_selection_internal, Fx_get_selection_internal)
18093 (Fx_disown_selection_internal, Fx_selection_owner_p)
18094 (Fx_selection_exists_p): New optional frame arg.
18095 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18096 (x_handle_selection_clear): Don't treat other terminals with the
18097 same keyboard specially. Use the terminal-local Vselection_alist.
18098 (x_clear_frame_selections): Use Frun_hook_with_args.
18100 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18102 * xterm.h: Add support for those atoms.
18104 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18106 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18107 (converted_selections, conversion_fail_tag): New global variables.
18108 (x_selection_request_lisp_error): Free the above.
18109 (x_get_local_selection): Remove unnecessary code.
18110 (x_reply_selection_request): Args changed; handle arbitrary array
18111 of converted selections stored in converted_selections.
18112 Separate the XChangeProperty and SelectionNotify steps.
18113 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18114 (x_convert_selection): New function.
18115 (x_handle_selection_event): Simplify.
18116 (x_get_foreign_selection): Don't ignore incoming requests while
18117 waiting for an answer; this will fail when we implement
18118 SAVE_TARGETS, and seems unnecessary anyway.
18119 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18120 (Vx_sent_selection_functions): Doc fix.
18122 2011-05-26 Leo Liu <sdl.web@gmail.com>
18124 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18126 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18128 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18130 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18131 for fringe update if it has periodic bitmap.
18132 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18133 and fringe_bitmap_periodic_p.
18135 * fringe.c (get_fringe_bitmap_data): New function.
18136 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18137 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18138 row. Mark glyph row for fringe update if periodicity changed.
18140 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18141 for fringe update unless it has periodic bitmap.
18143 2011-05-25 Kenichi Handa <handa@m17n.org>

18161 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18162 Remove macros that are defined and never used.
18163 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18165 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18167 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18168 (Fx_get_selection_internal): Minor cleanup.
18169 (Fx_own_selection_internal): Rename arguments for consistency with
18172 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

18196 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18198 * systime.h (Time): Define only if emacs is defined.
18199 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18200 where the include path doesn't have X11/X.h by default. See
18201 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18203 2011-05-20 Kenichi Handa <handa@m17n.org>
18205 * composite.c (find_automatic_composition): Fix previous change.
18207 2011-05-20 Glenn Morris <rgm@gnu.org>
18209 * lisp.mk: New file, split from Makefile.in.
18210 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18211 (shortlisp): Remove.
18212 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18214 2011-05-19 Glenn Morris <rgm@gnu.org>

18217 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18218 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18219 (lisp): Set the order to that of loadup.el.
18220 (shortlisp): Make it a copy of $lisp.
18221 (SOME_MACHINE_LISP): Remove.
18222 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18223 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18225 2011-05-18 Kenichi Handa <handa@m17n.org>
18227 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18228 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18229 (find_automatic_composition): Mostly rewrite for efficiency.
18231 2011-05-18 Juanma Barranquero <lekktu@gmail.com>

18235 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18237 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18238 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18240 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18242 Fix some integer overflow issues, such as string length overflow.
18244 * insdel.c (count_size_as_multibyte): Check for string overflow.
18246 * character.c (lisp_string_width): Check for string overflow.
18247 Use EMACS_INT, not int, for string indexes and lengths; in
18248 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18249 the resulting string length overflows an EMACS_INT; instead,
18250 report a string overflow if no precision given. When checking for
18251 precision exhaustion, use a check that cannot possibly have
18252 integer overflow. (Bug#8675)
18253 * character.h (lisp_string_width): Adjust to new signature.
18255 * alloc.c (string_overflow): New function.
18256 (Fmake_string): Use it. This doesn't change behavior, but saves
18257 a few bytes and will simplify future changes.
18258 * character.c (string_escape_byte8): Likewise.
18259 * lisp.h (string_overflow): New decl.
18261 Fixups, following up to the user-interface timestamp change.
18262 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18263 for UI timestamps, instead of unsigned long.
18264 * msdos.c (mouse_get_pos): Likewise.
18265 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18266 * w32gui.h (Time): Define by including "systime.h" rather than by
18267 declaring it ourselves. (Bug#8664)
18269 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18270 * image.c (clear_image_cache): Likewise.
18272 * term.c (term_mouse_position): Don't assume time_t wraparound.
18274 Be more systematic about user-interface timestamps.
18275 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18276 and sometimes 'EMACS_UINT', to represent these timestamps.
18277 This change causes it to use 'Time' uniformly, as that's what X uses.
18278 This makes the code easier to follow, and makes it easier to catch
18279 integer overflow bugs such as Bug#8664.
18280 * frame.c (Fmouse_position, Fmouse_pixel_position):
18281 Use Time, not unsigned long, for user-interface timestamps.
18282 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18283 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18284 * keyboard.h (last_event_timestamp): Likewise.
18285 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18286 * menu.h (xmenu_show): Likewise.
18287 * term.c (term_mouse_position): Likewise.
18288 * termhooks.h (struct input_event.timestamp): Likewise.
18289 (struct terminal.mouse_position_hook): Likewise.
18290 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18291 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18292 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18293 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18294 what it was before.
18295 * menu.h, termhooks.h: Include "systime.h", for Time.
18297 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18298 Don't assume that the difference between two unsigned long values
18299 can fit into an integer. At this point, we know button_down_time
18300 <= event->timestamp, so the difference must be nonnegative, so
18301 there's no need to cast the result if double-click-time is
18302 nonnegative, as it should be; check that it's nonnegative, just in
18303 case. This bug is triggered when events are more than 2**31 ms
18304 apart (about 25 days). (Bug#8664)
18306 * xselect.c (last_event_timestamp): Remove duplicate decl.
18307 (x_own_selection): Remove needless cast to unsigned long.
18309 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18310 that always fit in int. Use a sentinel instead of a counter, to
18311 avoid a temp and to allay GCC's concerns about possible int overflow.
18312 * frame.h (struct frame): Use int for menu_bar_items_used
18313 instead of EMACS_INT, since it always fits in int.
18315 * menu.c (grow_menu_items): Check for int overflow.
18317 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18319 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18320 Before, the code was not consistent. These values cannot exceed
18321 2**31 - 1 so there's no need to make them unsigned.
18322 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18323 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18324 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18326 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18328 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18329 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18330 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18331 presumably because the widths might not match.
18333 * window.c (size_window): Avoid needless test at loop start.
18335 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18337 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18339 2011-05-12 Drew Adams <drew.adams@oracle.com>
18341 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18343 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18345 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18346 `width' to `bar_area_x' and `bar_area_width', respectively.
18347 (x_scroll_run): Take account of fringe background extension.
18349 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18350 Rename local vars `left' and `width' to `bar_area_x' and
18351 `bar_area_width', respectively.
18352 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18353 background extension.
18355 2011-05-10 Jim Meyering <meyering@redhat.com>
18357 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18359 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18361 * image.c (Finit_image_library): Return t for built-in image types,
18362 like pbm and xbm. (Bug#8640)
18364 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18366 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18368 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18370 * w32console.c (Fset_screen_color): Doc fix.
18371 (Fget_screen_color): New function.
18372 (syms_of_ntterm): Defsubr it.
18374 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18375 unlink the temporary file if Fcall_process didn't create it in the
18377 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18378 child process will be redirected to a file specified with `:file'.
18379 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18380 cue to call_process_cleanup not to close that handle.
18382 2011-05-07 Ben Key <bkey76@gmail.com>
18384 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18385 one of two shell specific rules, either bootstrap-temacs-CMD or
18386 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18387 to the previous implementation of the bootstrap-temacs rule.
18388 The bootstrap-temacs-CMD rule is similar to the previous
18389 implementation of the bootstrap-temacs rule except that it
18390 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18393 These changes, along with some changes to nt/configure.bat,
18394 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18395 earlier fix to add support for --cflags and --ldflags options
18396 that include quotes so that it works whether make uses cmd or
18399 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18401 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18402 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18404 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18405 a string. Handle both cases.
18406 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18407 (Fdbus_register_method): Use Qinvalid_function.
18409 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18411 * makefile.w32-in: Update dependencies.
18412 (LISP_H): Add inttypes.h and stdin.h.
18413 (PROCESS_H): Add unistd.h.
18415 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18417 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18418 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18420 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18422 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18424 * term.c (vfatal): Remove stray call to va_end.
18425 It's not needed and the C Standard doesn't allow it here anyway.
18427 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18428 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18430 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18433 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18435 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18437 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18439 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18441 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18443 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18444 * charset.c (Fdefine_charset_internal): Don't initialize
18445 charset.code_space[15]. The value was garbage, on hosts with
18446 32-bit int (Bug#8600).
18448 * lread.c (read_integer): Be more consistent with string-to-number.
18449 Use string_to_number to do the actual conversion; this avoids
18450 rounding errors and fixes some other screwups. Without this fix,
18451 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18452 (digit_to_number): Move earlier, for benefit of read_integer.
18453 Return -1 if the digit is out of range for the base, -2 if it is
18454 not a digit in any supported base. (Bug#8602)
18456 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18458 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18459 to match comment at start of function. This also removes a
18460 GCC warning about overflow in a 32+64-bit port.
18462 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18464 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18465 Reported by Stefan Monnier in
18466 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18467 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18468 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18470 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18471 (EMACS_UINTPTR): Likewise, with uintptr_t.
18473 * lisp.h: Prefer 64-bit EMACS_INT if available.
18474 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18475 on 32-bit hosts that have 64-bit int, so that they can access
18477 However, temporarily disable this change unless the temporary
18478 symbol WIDE_EMACS_INT is defined.
18480 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18482 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18483 This removes an assumption that EMACS_INT and long are the same
18484 width as pointers. The assumption is true for Emacs porting targets
18485 now, but we want to make other targets possible.
18486 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18487 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18488 In the rest of the code, change types of integers that hold casted
18489 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18490 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18491 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18492 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18493 No need to cast type when ORing.
18494 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18495 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18496 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18497 assume EMACS_INT is the same width as char *.
18498 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18499 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18500 Remove no-longer-needed casts.
18501 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18502 (xg_tool_bar_help_callback, xg_make_tool_item):
18503 Use EMACS_INTPTR to hold an integer
18504 that will be cast to void *; this can avoid a GCC warning
18505 if EMACS_INT is not the same width as void *.
18506 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18507 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18508 (current_message_1, set_message_1):
18509 Use a local to convert to proper width without a cast.
18510 * xmenu.c (dialog_selection_callback): Likewise.
18512 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18513 Also, don't assume VALBITS / RAND_BITS is less than 5,
18514 and don't rely on undefined behavior when shifting a 1 left into
18516 * lisp.h (get_random): Change signature to match.
18518 * lread.c (hash_string): Use size_t, not int, for hash computation.
18519 Normally we prefer signed values; but hashing is special, because
18520 it's better to use unsigned division on hash table sizes so that
18521 the remainder is nonnegative. Also, size_t is the natural width
18522 for hashing into memory. The previous code used 'int', which doesn't
18523 retain enough info to hash well into very large tables.
18524 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18526 * dbusbind.c: Don't possibly lose pointer info when converting.
18527 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18528 Use XPNTR rather than XHASH, so that the high-order bits of
18529 the pointer aren't lost when converting through void *.
18531 * eval.c (Fautoload): Don't double-shift a pointer.
18533 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18535 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18537 * gnutls.c (DEF_GNUTLS_FN):
18538 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18540 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18542 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18545 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18547 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18548 New version that can reserve upto 2GB of heap space.
18550 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18552 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18554 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18556 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18557 `gnutls_certificate_set_x509_key_file'.
18559 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18561 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18562 Update dependencies.
18564 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18566 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18567 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18568 Remove unused parameter `fildes'.
18569 * process.c (read_process_output, send_process): Don't pass it.
18571 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18573 Fix previous change: the library cache is defined in w32.c.
18574 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18575 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18577 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18579 Implement dynamic loading of GnuTLS on Windows.
18581 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18582 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18583 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18586 * gnutls.c (Qgnutls_dll): Define.
18587 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18588 (gnutls_*): Declare function pointers.
18589 (init_gnutls_functions): New function to initialize function pointers.
18590 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18591 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18592 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18593 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18594 (emacs_gnutls_write, emacs_gnutls_read)
18595 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18596 (Fgnutls_available_p): New function.
18597 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18598 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18599 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18601 * image.c: Include w32.h.
18602 (Vimage_type_cache): Delete.
18603 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18604 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18605 (w32_delayed_load): Move to w32.c.
18607 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18609 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18610 (w32_delayed_load): Move from image.c. When loading a library, record
18611 its filename in the :loaded-from property of the library id.
18612 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18613 Initialize and staticpro them.
18614 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18616 * process.c: Include lisp.h before w32.h, not after.
18617 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18618 instead of gnutls_record_check_pending.
18620 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18622 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18624 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18625 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18628 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18630 * xterm.c (x_set_frame_alpha): Do not set property on anything
18631 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18633 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18635 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18637 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18639 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
18640 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
18641 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

18646 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
18647 (Qgnutls_bootprop_callbacks_verify): Make static.
18649 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18651 * callproc.c: Indentation fixup.
18653 * sysdep.c (wait_for_termination_1): Make static.
18654 (wait_for_termination, interruptible_wait_for_termination):
18655 Move after wait_for_termination_1.
18657 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18659 * sysdep.c (interruptible_wait_for_termination): New function
18660 which is like wait_for_termination, but allows keyboard
18663 * callproc.c (Fcall_process): Add (:file "file") as an option for
18665 (Fcall_process_region): Ditto.
18667 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18669 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18670 rather than `XVECTOR (FOO)->size'.
18672 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18673 inttypes.h, as a gnulib replacement is used if it not available in
18676 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18678 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18679 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18680 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18682 * coding.c (coding_alloc_by_realloc): Error out if destination
18683 will grow beyond MOST_POSITIVE_FIXNUM.
18684 (decode_coding_emacs_mule): Abort if there isn't enough place in
18685 charbuf for the composition carryover bytes. Reserve an extra
18686 space for up to 2 characters produced in a loop.
18687 (decode_coding_iso_2022): Abort if there isn't enough place in
18688 charbuf for the composition carryover bytes.
18690 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18692 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18693 aborting when %lld or %lll format is passed.
18694 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18695 %llo or %llx format is passed. (Bug#8545)
18697 * window.c (window_scroll_line_based): Use a marker instead of
18698 simple variables to record original value of point. (Bug#7952)
18700 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18701 produced by %s or %c overflows available buffer space. (Bug#8545)
18703 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18705 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18706 (SIZE_MAX): Move defn after all includes, as they might #define it.
18708 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18710 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18712 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18714 * keyboard.c (Qdelayed_warnings_hook): Define.
18715 (command_loop_1): Run `delayed-warnings-hook'
18716 if Vdelayed_warnings_list is non-nil.
18717 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18718 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18720 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18722 * doprnt.c (doprnt): Don't return value smaller than the buffer
18723 size if the message was truncated. (Bug#8545).
18725 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18727 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18728 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18730 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18732 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18734 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18736 * makefile.w32-in: Update dependencies.
18738 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18740 Improve `doprnt' and its usage. (Bug#8545)
18741 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18742 `format_end'. Remove support for %l as a conversion specifier.
18743 Don't use xrealloc. Improve diagnostics when the %l size modifier
18744 is used. Update the commentary.
18746 * eval.c (verror): Simplify calculation of size_t.
18748 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18751 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18753 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18756 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18758 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18759 This makes this file independent of the recent pseudovector change.
18761 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18763 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18765 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18766 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18767 Remove unused local.
18768 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18770 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18771 GCC 4.6.0 optimizes based on type-based alias analysis.
18772 For example, if b is of type struct buffer * and v of type struct
18773 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18774 != &v->size, and therefore "v->size = 1; b->size = 2; return
18775 v->size;" must therefore return 1. This assumption is incorrect
18776 for Emacs, since it type-puns struct Lisp_Vector * with many other
18777 types. To fix this problem, this patch adds a new type struct
18778 vectorlike_header that documents the constraints on layout of vectors
18779 and pseudovectors, and helps optimizing compilers not get fooled
18780 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18781 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18782 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18784 (XSETPVECTYPE): Rewrite in terms of new macro.
18785 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18786 This is a bit clearer, and further avoids the possibility of
18787 undesirable aliasing.
18788 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18789 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18790 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18791 since Lisp_Subr is a special case (no "next" field).
18792 (ASIZE): Now uses header.size rather than size.
18793 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18794 to avoid the hassle of writing XVECTOR (foo)->header.size.
18795 (struct vectorlike_header): New type.
18796 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18797 object, to help avoid aliasing.
18798 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18799 (SUBRP): Likewise, since Lisp_Subr is a special case.
18800 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18801 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18802 (struct Lisp_Hash_Table): Combine first two members into a single
18803 struct vectorlike_header member. All uses of "size" and "next" members
18804 changed to be "header.size" and "header.next".
18805 * buffer.h (struct buffer): Likewise.
18806 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18807 * frame.h (struct frame): Likewise.
18808 * process.h (struct Lisp_Process): Likewise.
18809 * termhooks.h (struct terminal): Likewise.
18810 * window.c (struct save_window_data, struct saved_window): Likewise.
18811 * window.h (struct window): Likewise.
18812 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18813 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18814 * buffer.c (init_buffer_once): Likewise.
18815 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18817 * process.c (Fformat_network_address): Use local var for size,
18820 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18822 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18823 * data.c (atof): Remove decl; no longer used or needed.
18824 (digit_to_number): Move to lread.c.
18825 (Fstring_to_number): Use new string_to_number function, to be
18826 consistent with how the Lisp reader treats infinities and NaNs.
18827 Do not assume that floating-point numbers represent EMACS_INT
18828 without losing information; this is not true on most 64-bit hosts.
18829 Avoid double-rounding errors, by insisting on integers when
18830 parsing non-base-10 numbers, as the documentation specifies.
18831 * lisp.h (string_to_number): New decl, replacing ...
18832 (isfloat_string): Remove.
18833 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18834 (read1): Do not accept +. and -. as integers; this
18835 appears to have been a coding error. Similarly, do not accept
18836 strings like +-1e0 as floating point numbers. Do not report
18837 overflow for integer overflows unless the base is not 10 which
18838 means we have no simple and reliable way to continue.
18839 Break out the floating-point parsing into a new
18840 function string_to_number, so that Fstring_to_number parses
18841 floating point numbers consistently with the Lisp reader.
18842 (digit_to_number): Move here from data.c. Make it static inline.
18843 (E_CHAR, EXP_INT): Remove, replacing with ...
18844 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18845 (string_to_number): New function, replacing isfloat_string.
18846 This function checks for valid syntax and produces the resulting
18847 Lisp float number too. Rework it so that string-to-number
18848 no longer mishandles examples like "1.0e+". Use strtoumax,
18849 so that overflow for non-base-10 numbers is reported only when
18850 there's no portable and simple way to convert to floating point.
18852 * textprop.c (set_text_properties_1): Rewrite for clarity,
18853 and to avoid GCC warning about integer overflow.
18855 * intervals.h (struct interval): Use EMACS_INT for members
18856 where EMACS_UINT might cause problems. See
18857 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18858 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18859 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18861 (offset_intervals): Tell GCC not to worry about length overflow
18862 when negating a negative length.
18864 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18865 (overrun_check_free): Likewise.
18867 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18868 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18871 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18872 (gnutls_make_error): Rename local to avoid shadowing.
18873 (gnutls_emacs_global_deinit): ifdef out; not used.
18874 (Fgnutls_boot): Use const for pointer to readonly storage.
18875 Comment out unused local. Fix pointer signedness problems.
18877 * lread.c (openp): Don't stuff size_t into an 'int'.
18878 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18879 about possible signed overflow.
18881 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18882 (GDK_KEY_g): Don't define if already defined.
18883 (xg_prepare_tooltip): Avoid pointer signedness problem.
18884 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18886 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18887 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18889 * xfns.c (Fx_window_property): Simplify a bit,
18890 to make a bit faster and to avoid GCC 4.6.0 warning.
18891 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18893 * fns.c (internal_equal): Don't assume size_t fits in int.
18895 * alloc.c (compact_small_strings): Tighten assertion a little.
18897 Replace pEd with more-general pI, and fix some printf arg casts.
18898 * lisp.h (pI): New macro, generalizing old pEd macro to other
18899 conversion specifiers. For example, use "...%"pI"d..." rather
18900 than "...%"pEd"...".
18901 (pEd): Remove. All uses replaced with similar uses of pI.
18902 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18903 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18904 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18905 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18906 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18907 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18908 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18910 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18911 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18912 * print.c (safe_debug_print, print_object): Likewise.
18913 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18915 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18916 avoiding the 0 flag, which is not portable.
18917 * process.c (Fmake_network_process): Use pI to avoid cast.
18918 * region-cache.c (pp_cache): Likewise.
18919 * xdisp.c (decode_mode_spec): Likewise.
18920 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18921 behavior on 64-bit hosts with printf arg.
18922 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18923 (x_stop_queuing_selection_requests): Likewise.
18924 (x_get_window_property): Don't truncate byte count to an 'int'
18927 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18928 here, since it parses constructs like leading '-' and spaces,
18929 which are not wanted; and it overflows with large numbers.
18930 Instead, simply match F[0-9]+, which is what is wanted anyway.
18932 * alloc.c: Remove unportable assumptions about struct layout.
18933 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18934 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18935 (allocate_vectorlike, make_pure_vector): Use the new macros,
18936 plus offsetof, to remove unportable assumptions about struct layout.
18937 These assumptions hold on all porting targets that I know of, but
18938 they are not guaranteed, they're easy to remove, and removing them
18939 makes further changes easier.
18941 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18942 This doesn't fix a bug but makes the code clearer.
18943 (string_overrun_cookie): Now const. Use initializers that
18944 don't formally overflow signed char, to avoid warnings.
18945 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18946 can cause Emacs to crash when string overrun checking is enabled.
18947 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18948 multiple of sizeof (EMACS_INT); it need not be, if
18949 alignof(EMACS_INT) < sizeof (EMACS_INT).
18950 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18952 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
18954 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
18956 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
18958 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
18959 supposed to be handshaking. (Bug#8556)
18960 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18962 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
18964 * lisp.h (Qdebug): List symbol.
18965 * eval.c (Qdebug): Restore global linkage.
18966 * keyboard.c (debug-on-event): New variable.
18967 (handle_user_signal): Break into debugger when debug-on-event
18968 matches the current signal symbol.
18970 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18972 * alloc.c (check_sblock, check_string_bytes)
18973 (check_string_free_list): Convert to standard C.
18975 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18977 * w32.c (emacs_gnutls_push): Fix typo.
18979 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18981 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18982 "cast to pointer from integer of different size".
18984 Improve doprnt and its use in verror. (Bug#8545)
18985 * doprnt.c (doprnt): Document the set of format control sequences
18986 supported by the function. Use SAFE_ALLOCA instead of always
18989 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18990 is one byte too soon. Don't use xrealloc; instead xfree and
18993 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18995 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18998 * gnutls.c: Renamed global_initialized to
18999 gnutls_global_initialized. Added internals for the
19000 :verify-hostname-error, :verify-error, and :verify-flags
19001 parameters of `gnutls-boot' and documented those parameters in the
19002 docstring. Start callback support.
19003 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19004 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19005 on error. Return error code.
19006 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19007 (emacs_gnutls_read): Likewise.
19008 (Fgnutls_boot): Return handshake error code.
19009 (emacs_gnutls_handle_error): New function.
19010 (wsaerror_to_errno): Likewise.

19015 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
19016 (emacs_gnutls_push): Likewise.
19018 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
19020 * process.c (wait_reading_process_output): Check if GnuTLS
19021 buffered some data internally if no FDs are set for TLS
19024 * makefile.w32-in (OBJ2): Add gnutls.$(O).
19025 (LIBS): Link to USER_LIBS.

19030 * xdisp.c (handle_single_display_spec): Rename the
19031 display_replaced_before_p argument into display_replaced_p, to
19032 make it consistent with the commentary. Fix typos in the
19035 * textprop.c (syms_of_textprop): Remove dead code.

19041 to changes in oldXMenu/XMenu.h from 2011-04-16.
19042 <menu_help_message, prev_menu_help_message>: Constify.
19043 (IT_menu_make_room): menu->help_text is now `const char **';
19046 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
19047 to changes in oldXMenu/XMenu.h from 2011-04-16.
19048 (struct XMenu): Declare `help_text' `const char **'.

19065 changes in globals.h immediately force recompilation.
19066 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19067 $(CURDIR)/s/ms-w32.h.
19068 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
19070 * character.c (Fchar_direction): Function deleted.
19071 (syms_of_character): Don't defsubr it.
19072 <char-direction-table>: Deleted.
19074 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19076 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19077 * doprnt.c: Include limits.h.
19078 (SIZE_MAX): New macro.
19079 (doprnt): Return a size_t value. 2nd arg is now size_t.
19080 Many local variables are now size_t instead of int or unsigned.
19081 Improve overflow protection. Support `l' modifier for integer
19082 conversions. Support %l conversion. Don't assume an EMACS_INT
19083 argument for integer conversions and for %c.
19085 * lisp.h (doprnt): Restore prototype.
19087 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19088 $(SRC)/character.h.
19090 * Makefile.in (base_obj): Add back doprnt.o.
19092 * deps.mk (doprnt.o): Add back prerequisites.
19093 (callint.o): Depend on character.h.
19095 * eval.c (internal_lisp_condition_case): Include the handler
19096 representation in the error message.
19097 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19098 when breaking from the loop.
19100 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19102 * callint.c (Fcall_interactively): When displaying error message
19103 about invalid control letter, pass the character's codepoint, not
19104 a pointer to its multibyte form. Improve display of the character
19105 in octal and display also its hex code.
19107 * character.c (char_string): Use %x to display the (unsigned)
19108 codepoint of an invalid character, to avoid displaying a bogus

19310 ns_descriptor_to_entity that were caused by using free to
19311 deallocate memory blocks that were allocated by xmalloc (via

19333 * process.c (send_process): Adjust to the new signatures of
19334 emacs_write and emacs_gnutls_write. Do not attempt to store

19677 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19678 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19679 was inaccessible from Lisp.

19701 * xdisp.c (message_enable_multibyte): Now static.
19703 Declare Lisp_Object Q* variables to be 'static' if not exported.
19704 This makes it easier for human readers (and static analyzers)
19705 to see whether these variables are used from other modules.

19719 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19721 Make Emacs functions such as Fatom 'static' by default.
19722 This makes it easier for human readers (and static analyzers)
19723 to see whether these functions can be called from other modules.
19724 DEFUN now defines a static function. To make the function external
19725 so that it can be used in other C modules, use the new macro DEFUE.

19731 Remove decls, since these functions are now static.
19732 (Funintern, Fget_internal_run_time): New decls, since these functions
19733 were already external.

19743 Mark functions with DEFUE instead of DEFUN,
19744 if they are used in other modules.
19745 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19746 decls for now-static functions.
19747 * buffer.h (Fdelete_overlay): Remove decl.

19783 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19785 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19786 when at ZV. (Bug#8487)
19788 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>

19799 (overrun_check_free): Protoize.
19801 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19803 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19804 since callers should never pass a negative size.
19805 Change the signature to match that of plain 'read' and 'write'; see
19806 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19807 * lisp.h: Update prototypes of emacs_write and emacs_read.
19809 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19811 * xdisp.c (redisplay_window): Don't try to determine the character
19812 position of the scroll margin if the window start point w->startp
19813 is outside the buffer's accessible region. (Bug#8468)
19815 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19817 Fix write-region and its subroutines for buffers > 2GB.
19818 * fileio.c (a_write, e_write): Modify declaration of arguments and
19819 local variables to support buffers larger than 2GB.
19820 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19822 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19823 argument, local variables, and return value.
19825 * lisp.h: Update prototypes of emacs_write and emacs_read.
19827 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19829 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19831 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19833 Fix more problems found by GCC 4.6.0's static checks.
19835 * xdisp.c (vmessage): Use a better test for character truncation.
19837 * charset.c (load_charset_map): <, not <=, for optimization,
19838 and to avoid potential problems with integer overflow.
19839 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19840 * casetab.c (set_identity, shuffle): Likewise.
19841 * editfns.c (Fformat): Likewise.
19842 * syntax.c (skip_chars): Likewise.
19844 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19845 This also lets GCC 4.6.0 generate slightly better loop code.
19847 * callint.c (Fcall_interactively): <, not <=, for optimization.
19848 (Fcall_interactively): Count the number of arguments produced,
19849 not the number of arguments given. This is simpler and lets GCC
19850 4.6.0 generate slightly better code.
19852 * ftfont.c: Distingish more carefully between FcChar8 and char.
19853 The previous code passed unsigned char * to a functions like
19854 strlen and xstrcasecmp that expect char *, which does not
19855 conform to the C standard.
19856 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19857 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19858 char * when the C standard requires it.
19860 * keyboard.c (read_char): Remove unused var.
19862 * eval.c: Port to Windows vsnprintf (Bug#8435).
19863 Include <limits.h>.
19864 (SIZE_MAX): Define if the headers do not.
19865 (verror): Do not give up if vsnprintf returns a negative count.
19866 Instead, grow the buffer. This ports to Windows vsnprintf, which
19867 does not conform to C99. Problem reported by Eli Zaretskii.
19868 Also, simplify the allocation scheme, by avoiding the need for
19869 calling realloc, and removing the ALLOCATED variable.
19871 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19873 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19874 But keep the doprint source code for now, as we might revamp it
19875 and use it again (Bug#8435).
19876 * lisp.h (doprnt): Remove.
19877 * Makefile.in (base_obj): Remove doprnt.o.
19878 * deps.mk (doprnt.o): Remove.
19880 error: Print 32- and 64-bit integers portably (Bug#8435).
19881 Without this change, on typical 64-bit hosts error ("...%d...", N)
19882 was used to print both 32- and 64-bit integers N, which relied on
19883 undefined behavior.
19884 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19885 * lisp.h (error, verror): Mark as printf-like functions.
19886 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19887 Report overflow in size calculations when allocating printf buffer.
19888 Do not truncate output string at its first null byte.
19889 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19890 Truncate the output at a character boundary, since vsnprintf does not
19892 * charset.c (check_iso_charset_parameter): Convert internal
19893 character to string before calling 'error', since %c now has the
19895 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19896 overflow when computing char to be passed to 'error'. Do not
19897 pass Lisp_Object to 'error'; pass the integer instead.
19898 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19899 formatted with plain %d.
19901 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19903 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19905 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19907 * xterm.c (x_catch_errors): Remove duplicate declaration.
19909 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19911 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19913 2011-04-10 Jim Meyering <meyering@redhat.com>
19915 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19916 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19917 return ssize_t not "int", and use size_t as the buffer length.
19918 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19919 * gnutls.h: Update declarations.
19920 * process.c (read_process_output): Use ssize_t, to match.
19921 (send_process): Likewise.
19923 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19925 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19927 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19929 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19930 Use unsigned char, to match FcChar8 type definition.
19932 * xterm.c (handle_one_xevent):
19933 * xmenu.c (create_and_show_popup_menu):
19934 * xselect.c (x_decline_selection_request)
19935 (x_reply_selection_request): Avoid type-punned deref of X events.
19937 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19939 Fix some uses of `int' instead of EMACS_INT.
19940 * search.c (string_match_1, fast_string_match)
19941 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19942 (scan_buffer, find_next_newline_no_quit)
19943 (find_before_next_newline, search_command, Freplace_match)
19944 (Fmatch_data): Make some `int' variables be EMACS_INT.
19946 * xdisp.c (display_count_lines): 3rd argument and return value now
19947 EMACS_INT. All callers changed.
19948 (pint2hrstr): Last argument is now EMACS_INT.
19950 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19951 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19952 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

19963 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19964 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19966 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19967 (encode_invocation_designation): Last argument P_NCHARS is now
19969 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19970 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19972 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.

19994 (Qhelp_form_show): New var.
19995 (syms_of_keyboard): Use DEFSYM macro.
19997 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20010 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20012 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20014 Fix more problems found by GCC 4.6.0's static checks.
20016 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

20020 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20022 * xdisp.c (vmessage): Mark as a printf-like function.
20024 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

20029 printf-like functions.
20030 (tiff_load): Add casts to remove these marks before passing them
20031 to system-supplied API.
20033 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20035 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20036 This avoids several warnings with gcc -Wstrict-overflow.
20037 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20038 directly, rather than having caller test rule sign. This avoids
20039 some unnecessary tests.
20040 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20041 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20042 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20044 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20045 (xfont_open): Avoid unnecessary tests.
20047 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20049 * composite.h, composite.c (composition_gstring_put_cache):
20050 Use EMACS_INT, not int, for length.
20052 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20053 breaking out part of COMPOSITION_DECODE_RULE.
20054 (COMPOSITION_DECODE_RULE): Use it.
20055 * composite.c (get_composition_id): Remove unused local vars,
20056 by using the new macro.
20058 * textprop.c (set_text_properties_1): Change while to do-while,
20059 since the condition is always true at first.
20061 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20062 (interval_deletion_adjustment): Return unsigned value.
20065 * process.c (list_processes_1, create_pty, read_process_output):
20066 (exec_sentinel): Remove vars that were set but not used.
20067 (create_pty): Remove unnecessary "volatile"s.
20068 (Fnetwork_interface_info): Avoid possibility of int overflow.

20074 * syntax.c (scan_words): Remove var that was set but not used.
20075 (update_syntax_table): Use unsigned instead of int.
20077 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20078 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20079 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20081 * print.c (print_error_message): Avoid int overflow.
20083 * font.c (font_list_entities): Redo for clarity,
20084 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20086 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20087 (font_score): Avoid potential overflow in diff calculation.
20089 * fns.c (substring_both): Remove var that is set but not used.
20090 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20092 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20094 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20095 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20096 can always succeed if overflow has undefined behavior.
20098 * search.c (boyer_moore, wordify): Remove vars set but not used.
20099 (wordify): Omit three unnecessary tests.
20101 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20102 All callers changed. This avoids the need for an unused var.
20104 * casefiddle.c (casify_region): Remove var that is set but not used.
20106 * dired.c (file_name_completion): Remove var that is set but not used.
20108 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20110 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20111 (Finsert_file_contents): Remove unnecessary code checking fd.
20113 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20114 Check for integer overflow on size calculations.
20116 * buffer.c (Fprevious_overlay_change): Remove var that is set
20119 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20120 Remove vars that are set but not used.
20121 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20122 (timer_check_2): Mark vars as initialized.
20124 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20126 * image.c (lookup_image): Remove var that is set but not used.
20127 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20129 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20130 that are set but not used.
20132 * xfns.c (make_invisible_cursor): Don't return garbage
20133 if XCreateBitmapFromData fails (Bug#8410).
20135 * xselect.c (x_get_local_selection, x_handle_property_notify):
20136 Remove vars that are set but not used.
20138 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20139 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20141 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20142 Remove var that is set but not used.
20143 (scroll_bar_windows_size): Now size_t, not int.
20144 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20145 Check for overflow.
20147 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20148 (map_tty_color) [!defined MSDOS]: Likewise.
20150 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20152 * coding.c: Remove vars that are set but not used.
20153 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20154 All callers changed.
20155 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20156 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20157 (decode_coding_charset): Remove vars that are set but not used.
20159 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20160 that is set but not used.
20162 * print.c (print_object): Remove var that is set but not used.
20164 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20165 The gnulib version avoids calling malloc in the usual case,
20166 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20167 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20168 * filelock.c (current_lock_owner): Likewise.
20169 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20170 * sysdep.c: Include allocator.h, careadlinkat.h.
20171 (emacs_no_realloc_allocator): New static constant.
20172 (emacs_readlink): New function.
20173 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20174 ../lib/careadlinkat.h.
20176 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20178 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20179 first non-nil return value).
20181 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20183 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20184 if not defined (Bug#8403).
20186 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20188 * xdisp.c (display_count_lines): Remove parameter `start',
20189 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20190 (get_char_face_and_encoding): Remove parameter `multibyte_p',
20191 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20193 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20194 and thereabouts. All callers changed.
20195 (get_per_char_metric): Remove parameter `f', unused since
20196 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20198 2011-04-02 Jim Meyering <meyering@redhat.com>
20200 do not dereference NULL upon failed strdup
20201 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20202 (ns_get_family): Likewise.
20204 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20206 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20208 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20210 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20213 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20215 Add lexical binding.
20217 * window.c (Ftemp_output_buffer_show): New fun.
20218 (Fsave_window_excursion):
20219 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20221 * lread.c (lisp_file_lexically_bound_p): New function.
20222 (Fload): Bind Qlexical_binding.
20223 (readevalloop): Remove `evalfun' arg.
20224 Bind Qinternal_interpreter_environment.
20225 (Feval_buffer): Bind Qlexical_binding.
20226 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20228 (syms_of_lread): Declare `lexical-binding'.
20230 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20232 * keyboard.c (eval_dyn): New fun.
20233 (menu_item_eval_property): Use it.
20235 * image.c (parse_image_spec): Use Ffunctionp.
20237 * fns.c (concat, mapcar1): Accept byte-code-functions.
20239 * eval.c (Fsetq): Handle lexical vars.
20240 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20241 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20242 (FletX, Flet): Obey lexical binding.
20243 (Fcommandp): Handle closures.
20244 (Feval): New `lexical' arg.
20245 (eval_sub): New function extracted from Feval. Use it almost
20246 everywhere where Feval was used. Look up vars in lexical env.
20248 (Ffunctionp): Move from subr.el.
20249 (Ffuncall): Handle closures.
20250 (apply_lambda): Remove `eval_flags'.
20251 (funcall_lambda): Handle closures and new byte-code-functions.
20252 (Fspecial_variable_p): New function.
20253 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20254 but without exporting it to Lisp.
20256 * doc.c (Fdocumentation, store_function_docstring):
20257 * data.c (Finteractive_form): Handle closures.
20259 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20262 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20264 (exec_byte_code): New function extracted from Fbyte_code to handle new
20265 calling convention for byte-code-functions. Add new byte-codes.
20267 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20269 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20271 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20273 * xdisp.c (redisplay_internal): Fix prototype.
20275 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20277 * xdisp.c (SCROLL_LIMIT): New macro.
20278 (try_scrolling): Use it when setting scroll_limit.
20279 Limit scrolling to 100 screen lines.
20280 (redisplay_window): Even when falling back on "recentering",
20281 position point in the window according to scroll-conservatively,
20282 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20284 (try_scrolling): When point is above the window, allow searching
20285 as far as scroll_max, or one screenful, to compute vertical
20286 distance from PT to the scroll margin position. This prevents
20287 try_scrolling from unnecessarily failing when
20288 scroll-conservatively is set to a value slightly larger than the
20289 window height. Clean up the case of PT below the margin at bottom
20290 of window: scroll_max can no longer be INT_MAX. When aggressive
20291 scrolling is in use, don't let point enter the opposite scroll
20292 margin as result of the scroll.
20293 (syms_of_xdisp) <scroll-conservatively>: Document the
20294 threshold of 100 lines for never-recentering scrolling.
20296 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20298 * dispextern.h (move_it_by_lines):
20299 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20300 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20301 (message_log_check_duplicate): Remove parameters `prev_bol' and
20302 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20303 (redisplay_internal): Remove parameter `preserve_echo_area',
20304 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20306 * indent.c (Fvertical_motion):
20307 * window.c (window_scroll_pixel_based, Frecenter):
20308 Don't pass `need_y_p' to `move_it_by_lines'.
20310 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20312 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20313 steal a few bits to be more compact.
20314 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20315 Remove unneeded casts.
20317 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20319 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20321 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20322 binding" message (bug#7967).
20324 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20326 Fix more problems found by GCC 4.6.0's static checks.
20328 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20329 Remove unused local var.
20331 * editfns.c (Fmessage_box): Remove unused local var.
20333 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20334 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20335 Omit unused local vars.
20336 * window.c (shrink_windows): Omit unused local var.
20337 * menu.c (digest_single_submenu): Omit unused local var.
20338 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20339 Omit unused local var.
20341 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20342 Don't assume string length fits in int.
20343 (keyremap_step, read_key_sequence): Use size_t for sizes.
20344 (read_key_sequence): Don't check last_real_key_start redundantly.
20346 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20347 instead of alloca (Bug#8344).
20349 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20350 (Fbacktrace_frame): Don't assume nframes fits in int.
20352 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20354 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20357 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20359 * cm.c (calccost): Turn while-do into do-while, for clarity.
20361 * keyboard.c (syms_of_keyboard): Use the same style as later
20362 in this function when indexing through an array. This also
20363 works around GCC bug 48267.
20365 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20367 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20369 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20370 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20372 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20373 This avoids undefined behavior on integer overflow, and is a bit
20374 more convenient anyway since it is compared to a size_t variable.
20376 Variadic C functions now count arguments with size_t, not int.
20377 This avoids an unnecessary limitation on 64-bit machines, which
20378 caused (substring ...) to crash on large vectors (Bug#8344).
20379 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20380 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20381 All variadic functions and their callers changed accordingly.

20388 * fns.c (concat): Likewise.
20389 * frame.c (x_set_frame_parameters): Likewise.
20390 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20391 0 if not found, not -1. All callers changed.
20393 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20394 (stack_copy_size): Now size_t, not int.
20395 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20397 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20399 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20400 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20401 All callers changed.
20403 * lisp.h (multibyte_char_to_unibyte):
20404 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20405 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20406 * character.h (CHAR_TO_BYTE8):
20407 * cmds.c (internal_self_insert):
20408 * editfns.c (general_insert_function):
20409 * keymap.c (push_key_description):
20410 * search.c (Freplace_match):
20411 * xdisp.c (message_dolog, set_message_1): All callers changed.
20413 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
20415 * keyboard.c (safe_run_hook_funcall): New function.
20416 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20417 don't set the hook to nil, but remove the offending function instead.
20418 (Qcommand_hook_internal): Remove, unused.
20419 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20420 Vcommand_hook_internal.
20422 * eval.c (enum run_hooks_condition): Remove.
20423 (funcall_nil, funcall_not): New functions.
20424 (run_hook_with_args): Call each function through a `funcall' argument.
20425 Remove `cond' argument, now redundant.
20426 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
20427 (Frun_hook_with_args_until_failure): Adjust accordingly.
20428 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
20430 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

20600 * buffer.c (Fkill_all_local_variables):
20601 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20603 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20604 unconditionally since it does the check itself.
20606 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20608 Fix more problems found by GCC 4.5.2's static checks.
20610 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20611 the first time through the loop, since we know p0 < p1 then.
20612 This also avoids a gcc -Wstrict-overflow warning.
20614 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20615 leading to a memory leak, possible in functions like
20616 load_charset_map_from_file that can allocate an unbounded number
20617 of objects (Bug#8318).
20619 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20620 that could (at least in theory) be that large.
20622 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20623 This is less likely to overflow, and avoids undefined behavior if
20624 overflow does occur. All callers changed. Use strtoul to scan
20625 for the unsigned long integer.
20626 (pint2hrstr): Simplify and tune code slightly.
20627 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20642 * process.c (Fmake_network_process): Use socklen_t, not int,
20643 where POSIX says socklen_t is required in portable programs.
20644 This fixes a porting bug on hosts like 64-bit HP-UX, where
20645 socklen_t is wider than int (Bug#8277).
20646 (Fmake_network_process, server_accept_connection):
20647 (wait_reading_process_output, read_process_output):
20650 * process.c: Rename or move locals to avoid shadowing.

20660 Make tparam.h and terminfo.c consistent.
20661 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20662 Include tparam.h instead, since it declares them.
20663 * cm.h (PC): Remove extern decl; tparam.h now does this.
20664 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20665 * terminfo.c: Include tparam.h, to check interfaces.
20666 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20667 (tparam): Adjust signature to match interface in tparam.h;
20668 this removes some undefined behavior. Check that outstring and len
20669 are zero, which they always are with Emacs.
20670 * tparam.h (PC, BC, UP): New extern decls.
20672 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20673 (xftfont_open): Rename locals to avoid shadowing.

20691 (composition_update_it): Mark var as initialized.
20692 (find_automatic_composition): Mark vars as initialized,
20693 with a FIXME (Bug#8290).

20699 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20700 to avoid shadowing.

20712 Fix pointer signedness.
20713 (alsa_choose_format): Remove unused local var.
20714 (wav_play): Initialize a variable to 0, to prevent undefined
20715 behavior (Bug#8278).
20717 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20719 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20721 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20722 clobbering (Bug#8298).
20723 * sysdep.c (sys_subshell): Likewise.
20724 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20726 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20727 This should get cleaned up, so that child_setup has the
20728 same signature on all platforms.
20730 * callproc.c (call_process_cleanup): Now static.
20731 (relocate_fd): Rename locals to avoid shadowing.
20733 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20735 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20736 not to be necessary, and produces flickering.
20738 2011-03-20 Glenn Morris <rgm@gnu.org>
20740 * config.in: Remove file.
20742 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

20789 * unexelf.c (unexec): Name an expression,
20790 to avoid gcc -Wbad-function-cast warning.

20792 n rather than nn, a way that does not involve shadowing.
20793 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20795 * deps.mk (unexalpha.o): Remove; unused.

20884 Rename locals to avoid shadowing.
20885 (mark_stack): Move local variables into the #ifdef region where
20887 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
20888 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
20890 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
20891 (GC_STRING_CHARS): Remove; not used.
20892 (Fmemory_limit): Cast sbrk's returned value to char *.
20894 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
20895 avoids undefined behavior in theory.
20897 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
20899 Use functions, not macros, for up- and down-casing (Bug#8254).
20900 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20901 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20902 to use the following functions instead of these macros.
20903 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20904 EMACS_INT, since callers assume the returned value fits in int.
20905 (upcase1): Likewise, for UPCASE_TABLE.
20906 (uppercasep, lowercasep, upcase): New static inline functions.
20907 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
20908 the race-condition problem in the old DOWNCASE.
20910 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
20911 Rename locals to avoid shadowing.
20912 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
20913 (regex_compile, re_search_2, re_match_2_internal):
20914 Remove unused local vars.

20916 which gcc can warn about.
20917 (regex_compile, re_match_2_internal): Mark locals as initialized.
20918 (RETALLOC_IF): Define only if needed.
20919 (WORDCHAR_P): Likewise. This one is never needed, but is used
20920 only in a comment talking about a compiler bug, so put inside
20921 the #if 0 of that comment.
20922 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20923 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
20926 * search.c (boyer_moore): Rename locals to avoid shadowing.
20927 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

20938 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.

20949 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20950 New macros, so that the caller can use some names other than
20951 gcpro1, gcpro2, etc.
20952 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20954 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20955 argument, for consistency with GCPRO2_VAR, etc: it is now the
20956 prefix of the variable, not the variable itself. All uses
20958 * dired.c (directory_files_internal, file_name_completion):
20959 Rename locals to avoid shadowing.
20961 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20962 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20963 dired.c's scmp function, had undefined behavior.
20964 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20965 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20966 * buffer.h: ... to here, because these macros use current_buffer,
20967 and the new implementation with inline functions needs to have
20968 current_buffer in scope now, rather than later when the macros
20970 (downcase, upcase1): New static inline functions.
20971 (DOWNCASE, UPCASE1): Reimplement using these functions.
20972 This avoids undefined behavior in expressions like
20973 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20974 from race conditions in accessing the global variables
20975 case_temp1 and case_temp2.
20976 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20977 * lisp.h (case_temp1, case_temp2): Remove their decls.
20978 * character.h (ASCII_CHAR_P): Move from here ...
20979 * lisp.h: ... to here, so that the inline functions mentioned
20980 above can use them.
20982 * dired.c (directory_files_internal_unwind): Now static.
20984 * fileio.c (file_name_as_directory, directory_file_name):
20985 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
20987 (file_name_as_directory): Use const pointers when appropriate.
20988 (Fexpand_file_name): Likewise. In particular, newdir might
20989 point at constant storage, so make it a const pointer.
20990 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20991 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20993 (Fset_file_times, Finsert_file_contents, auto_save_error):

20998 to avoid shadowing.
21000 * marker.c (bytepos_to_charpos): Remove; unused.
21002 * lisp.h (verify_bytepos, count_markers): New decls,
21003 so that gcc does not warn that these functions aren't declared.
21005 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21006 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21007 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21008 (copy_text): Remove unused local var.
21010 * filelock.c (within_one_second): Now static.
21011 (lock_file_1): Rename local to avoid shadowing.
21013 * buffer.c (fix_overlays_before): Mark locals as initialized.
21014 (fix_start_end_in_overlays): Likewise. This function should be
21015 simplified by using pointers-to-pointers, but that's a different
21017 (switch_to_buffer_1): Now static.
21018 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21019 (report_overlay_modification): Rename locals to avoid shadowing.
21021 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21022 Fix pointer signedness issue.
21023 (sys_subshell): Mark local as volatile if checking for lint,
21024 to suppress a gcc -Wclobbered warning that does not seem to be right.
21025 (MAXPATHLEN): Define only if needed.
21027 * process.c (serial_open, serial_configure): Move decls from here ...
21028 * systty.h: ... to here, so that they can be checked.
21030 * fns.c (get_random, seed_random): Move extern decls from here ...
21031 * lisp.h: ... to here, so that they can be checked.
21033 * sysdep.c (reset_io): Now static.
21034 (wait_for_termination_signal): Remove; unused.
21036 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21041 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21042 (describe_map_tree):
21043 Rename locals to avoid shadowing.

21194 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
21195 reports time overflow. See
