17 * keyboard.c (echo_add_char): New function, factored out from
18 echo_char. Don't add a space if the previous echo string was
21 (read_key_sequence): When echoing mock input, ensure that the
22 trailing dash is properly added.
24 2013-01-05 Eli Zaretskii <eliz@gnu.org>
26 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
27 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
28 digits for buffer positions, before misalignment starts.
29 Display "0" for integer "object" field.
30 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
31 Display the newline glyph more unambiguously.
33 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
35 * nsterm.m (ns_draw_underwave):
36 * w32term.c (w32_draw_underwave):
37 * xterm.c (x_draw_underwave): Make underwave look more triangular
38 and also degrade gracefully for small fonts. (Bug#13000)
40 * nsterm.m (ns_draw_text_decoration):
41 * w32term.c (x_draw_glyph_string):
42 * xterm.c (x_draw_glyph_string): Don't use previous underline
43 thickness and position if previous underline type is underwave.

51 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
53 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
56 * dired.c (file_name_completion):
57 * doc.c (get_doc_string):
58 * floatfns.c (round2):
59 * font.c (font_score, font_delete_unmatched):
60 * fringe.c (compute_fringe_widths):
61 * lread.c (read_list):
62 * minibuf.c (Ftry_completion):
63 * term.c (tty_ins_del_lines):
64 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
65 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
67 2012-12-31 Eli Zaretskii <eliz@gnu.org>
69 * w32.c (unsetenv): Set up the string passed to _putenv
71 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
72 for the bug this caused.
74 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
76 * coding.c (Qmac): Now static.
78 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
80 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
81 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
82 handlebox_widget. Set toolbar_in_hbox to false/true, set
83 toolbar_is_packed to true.
84 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
85 (update_frame_tool_bar): Check toolbar_is_packed for packing.
86 Show all on TOOLBAR_TOP_WIDGET.
87 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
88 by TOOLBAR_TOP_WIDGET.
89 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
90 Check toolbar_is_packed.
91 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
92 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
93 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
95 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
96 (xg_update_menubar): Update title only if
97 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
98 (xg_update_submenu): Skip tearoff only if
99 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
100 (xg_initialize): Initialize xg_detached_menus only if
101 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
103 * xterm.h (struct x_output): Surround handlebox_widget with
104 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
105 toolbar_in_hbox is bool.
107 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
109 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
110 (LIBS_GNUSTEP): Define.
111 (LIBES): Add $(LIBS_GNUSTEP).
112 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
114 2012-12-30 Eli Zaretskii <eliz@gnu.org>
116 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
117 continuation glyph on a TTY with an indication of an empty line.
120 2012-12-29 Eli Zaretskii <eliz@gnu.org>
122 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
123 file's SELinux context or ACLs successfully set, nil otherwise.
125 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
127 * w32proc.c (reader_thread): Avoid passing NULL handles to
128 SetEvent and WaitForSingleObject.
130 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
132 Port EXTERNALLY_VISIBLE to Clang 3.2.
133 * conf_post.h (__has_attribute): New macro.
134 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
136 2012-12-27 Glenn Morris <rgm@gnu.org>
138 * cygw32.c (Fcygwin_convert_file_name_to_windows)
139 (Fcygwin_convert_file_name_from_windows): Doc fixes.
141 2012-12-27 Eli Zaretskii <eliz@gnu.org>
143 * fileio.c (file_name_as_directory, directory_file_name):
144 Accept an additional argument MULTIBYTE to indicate whether the input C
145 came from a multibyte or a unibyte Lisp string; all callers
146 adjusted. Don't assume the input string is always multibyte.
148 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
149 don't ENCODE_FILE them, and return a unibyte string if the input
151 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
152 don't assume the input strings will always be multibyte. If the
153 input strings are multibyte, decode strings obtained from C
156 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
158 * lisp.h (toplevel): Add two notices to the comment about
159 defining a new Lisp data type.
160 * print.c (print_object): If Lisp_Save_Value object's pointer
161 is the address of a memory area containing Lisp_Objects, try
163 * alloc.c (valid_lisp_object_p): Adjust comment.
165 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
167 * keyboard.c (record_asynch_buffer_change): Initialize an event
168 only if it's really needed.
169 * frame.h (enum output_method): Remove output_mac member since
170 it's a leftover from the deleted code.
171 * frame.c (Fframep): Adjust user here ...
172 * terminal.c (Fterminal_live_p): ... and here.
173 * coding.c (Qmac): Now here because it's only used to denote
174 end-of-line encoding type.
175 (syms_of_coding): DEFSYM it.
176 * frame.h (Qmac): Remove duplicated declaration.
178 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
180 * window.c (select_window_1): Now static, since it's used only here.
182 2012-12-25 Eli Zaretskii <eliz@gnu.org>
184 * window.c (window_body_cols): Subtract display margins from the
185 window body width on TTYs as well. See
186 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
187 for the original report.
189 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
191 * xdisp.c (redisplay_window): Remove inner local variable
192 because the outer shadowed one has the same meaning.
193 * xterm.h (struct x_output): Remove toolbar_detached member since it's
195 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
196 (xg_create_tool_bar): Adjust users.
198 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
200 * buffer.h (BUF_COMPACT): New macro to follow the common style.
201 * buffer.c (Fget_buffer_create): Use it to set compact field of
202 struct buffer_text to avoid accessing an uninitialized value
203 when compact_buffer is called for the first time.
204 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
205 (Fset_buffer_modified_p): Use buffer_window_count to check
206 whether the buffer is displayed in some window.
207 * xdisp.c (message_dolog): Likewise.
209 2012-12-23 Eli Zaretskii <eliz@gnu.org>
211 * w32.c (acl_set_file): If setting the file security descriptor
212 fails, and the new DACL is identical to the existing one, silently
213 return success. This fixes problems for users backing up their
214 own files without having the necessary privileges for setting
215 security descriptors.
217 * w32proc.c (reader_thread): Do not index fd_info[] with negative
219 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
220 after WaitForSingleObject returns normally. This expedites reader
221 thread shutdown when delete_child triggers it.
222 (reap_subprocess): More accurate commentary for why we call
223 delete_child only when cp->fd is negative.
225 * w32.c (sys_close): Do not call delete_child on a subprocess
226 whose handle is not yet closed. Instead, set its file descriptor
227 to a negative value, so that reap_subprocess will call
228 delete_child on that subprocess when its SIGCHLD arrives.
229 This avoids closing handles used for communications between sys_select
230 and reader_thread, which doesn't give sys_select a chance to
231 notice that the process exited and invoke the SIGCHLD handler for
234 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
236 * nsfns.m (Fns_do_applescript): Run event loop until script has
237 been executed (Bug#12969).
238 (ns_run_ascript): Chech as_script for nil, set to nil after
241 2012-12-22 Martin Rudalics <rudalics@gmx.at>
243 * window.c (Fselect_window): Reword doc-string (Bug#13248).
245 2012-12-22 Eli Zaretskii <eliz@gnu.org>
247 * w32term.c (w32fullscreen_hook): New function.
248 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
250 2012-12-21 Eli Zaretskii <eliz@gnu.org>
252 * fileio.c (Finsert_file_contents): Doc fix.
254 * w32proc.c (new_child, delete_child, find_child_pid): For a
255 subprocess, consider its slot being in use as long as its process
256 handle (procinfo.hProcess) is not NULL. This avoids reusing the
257 slot when a new process is started immediately after killing
258 another one, without waiting enough time for the first process to
259 be reaped and resources allocated for it be orderly freed.
261 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
263 2012-12-21 Chong Yidong <cyd@gnu.org>
265 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
267 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
269 2012-12-21 Eli Zaretskii <eliz@gnu.org>
271 * w32.c (get_name_and_id): Always pass NULL as the first argument
272 of lookup_account_sid. Avoids crashes with UNC file names that
273 refer to DFS domains, not to specific machine names. (Bug#12621)
274 Remove now unused argument FNAME; all callers changed.
275 (get_file_owner_and_group): Remove now unused argument FNAME; all
278 2012-12-21 Chong Yidong <cyd@gnu.org>
280 * editfns.c (Finsert_char): Since read-char-by-name now signals an
281 error for invalid chars, don't check for a nil return value.
283 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
285 Avoid calls to CHAR_TO_BYTE if byte position is known.
286 * editfns.c (make_buffer_string_both): Use move_gap_both.
287 (Fbuffer_string): Use make_buffer_string_both.
288 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
290 (buf_bytepos_to_charpos): Likewise.
291 (charpos_to_bytepos): Remove.
292 * fileio.c (Finsert_file_contents): Use move_gap_both.
293 * search.c (Freplace_match): Likewise.
294 * process.c (process_send_region): Likewise. Use convenient
295 names for byte positions.
296 * lisp.h (charpos_to_bytepos): Remove prototype.
297 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
298 * insdel.c (move_gap): Likewise.
300 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
302 * xdisp.c (redisplay_internal): Remove now-unused local.
304 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
306 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
307 (redisplay_internal): Don't bother selecting the frame to get the
308 proper value of frame-local variables (bug#13225).
310 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
312 * textprop.c (set_text_properties_1): Do not allow NULL interval.
313 Rename 4th argument since it may be buffer or string. Adjust comment.
314 * intervals.c (graft_intervals_info_buffer): Find an interval here.
316 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
318 * coding.c (Fdetect_coding_region): Do not check start and end with
319 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
320 (code_convert_region): Likewise.
322 2012-12-18 Eli Zaretskii <eliz@gnu.org>
324 * w32.c (acl_get_file, acl_set_file): Run the file name through
325 map_w32_filename, and resolve any symlinks in the file name, like
327 (acl_set_file): Call revert_to_self, if any privileges were
330 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
332 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
333 ($(BLD)/w32.$(O)): Update dependencies.
335 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
337 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
338 propagate redisplay's scrolling (if any) to the right window.
339 (redisplay_internal): Use ensure_selected_frame.
340 (display_mode_lines): Complete last fix.
341 * window.c (select_window_1): New func, extracted from select_window.
342 (select_window): Use it.
343 * window.h (select_window_1): Declare.
345 2012-12-17 Eli Zaretskii <eliz@gnu.org>
347 Emulate Posix ACL APIs on MS-Windows.
348 * w32.c: Include sddl.h and sys/acl.h.
349 (SDDL_REVISION_1): Define if not already defined.
350 (g_b_init_get_security_descriptor_dacl)
351 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)

361 (get_security_descriptor_group): Set errno to ENOTSUP.
362 (set_file_security, get_security_descriptor_dacl)
363 (is_valid_security_descriptor, convert_sd_to_sddl)
364 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
365 (acl_free, acl_get_file, acl_set_file): New functions.
367 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
369 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
371 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
372 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
373 for some of that bug's symptoms can now cause Emacs to abort.
374 Remove the workaround.
375 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
376 The bug that caused SIGCHLD to get lost has been fixed, and the
377 workaround for it can now cause Emacs to abort.
379 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
381 * sysdep.c (emacs_abort): Bump backtrace size to 40.
382 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
383 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
385 2012-12-16 Romain Francoise <romain@orebokech.com>
387 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
388 (Fcopy_file): Change last arg to `preserve_extended_attributes'
389 and copy ACL entries of file in addition to SELinux context if set.
390 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
392 * Makefile.in (LIBACL_LIBS): New macro.
395 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
397 * fileio.c (internal_delete_file): Use bool for boolean.
399 2012-12-15 Eli Zaretskii <eliz@gnu.org>
401 Fix bug #13079 on MS-Windows with temp files not being deleted.
402 * w32.h (_child_process): New members input_file and
404 (register_child): First argument is now pid_t.
405 (record_infile, record_pending_deletion): New prototypes.
407 * w32proc.c (new_child): Initialize input_file and
408 pending_deletion members of the child.
409 (delete_child): Delete the child's temporary input file, if any,
410 that is pending deletion.
411 (register_child): First argument is now pid_t.
412 (record_infile, record_pending_deletion): New functions.
413 (reap_subprocess): Fix a typo in DebPrint string.
414 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
416 * fileio.c (internal_delete_file): Return an int again: non-zero
417 if delete-file succeeds, zero otherwise.
419 * lisp.h (internal_delete_file): Adjust prototype.
421 * callproc.c (Fcall_process): Don't overwrite infile with result
423 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
424 asynchronous subprocess, record the name of the input file name,
426 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
427 delete the file, record it as pending deletion when the subprocess
430 2012-12-14 Eli Zaretskii <eliz@gnu.org>
432 * editfns.c [HAVE_PWD_H]: Include grp.h.
434 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
436 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
438 Fix permissions bugs with setgid directories etc. (Bug#13125)
439 * dired.c (Ffile_attributes): Return t as the 9th attribute,
440 to mark it as a placeholder. The old value was often wrong.
441 The only user of this attribute has been changed to use
442 file-ownership-preserved-p instead, with its new group arg.
443 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
445 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

448 Keep selected_window and selected_frame in sync.
450 2012-12-14 Eli Zaretskii <eliz@gnu.org>
452 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
453 try to get accurate owner and group information from NT file
454 security APIs. This is to make most callers of 'stat' and
455 'lstat', which don't need that information, much faster.
457 * dired.c (Ffile_attributes) [WINDOWSNT]:
458 Set w32_stat_get_owner_group to a non-zero value, to request accurate
459 owner and group information from 'lstat'.
461 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
463 * fileio.c (Finsert_file_contents): Don't put tail into head area,
464 as that confuses set-auto-coding, so insist on the head-read
465 returning the full 1024 bytes. Let lseek compute the tail offset;
466 less work for us. Do not ignore I/O errors when reading the tail.
468 * xdisp.c: Minor style fixes.
469 (init_iterator): Hoist assignment out of if-expression.
470 (markpos_of_region): Callers now test for sign, not for -1.
472 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
474 Minor redisplay optimization when the region length is zero.
475 * xdisp.c (markpos_of_region): New function.
476 (init_iterator): Do not highlight the region of zero length.
477 (redisplay_window): Check whether the region is of non-zero length.
478 (try_cursor_movement): Allow if the region length is zero.
479 (try_window_reusing_current_matrix, try_window_id): Likewise.
481 2012-12-13 Eli Zaretskii <eliz@gnu.org>
483 * search.c (search_buffer): Check the inverse translations of each
484 character in pattern when the buffer being searched is unibyte.
487 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
489 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
490 files, fixing a regression from 24.2.
491 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
493 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
495 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
496 fstat shouldn't fail, and if it does fail copy-file should not proceed.
497 Remove unnecessary S_ISLNK test, as (contra the comments) this
498 function can't copy symlinks. Improve quality of error message
499 when attempting to copy files that are neither regular files nor
502 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
504 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.

582 (hinst): Remove unneeded extern declaration.
583 (_start): Remove initialization of above variables; remove

726 * w32.c (unsetenv): Return 0 if the input string is too long.
728 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>

745 no longer needed here.
746 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
747 Move to inside set_time_zone_rule; they don't need file scope any more.
748 (set_time_zone_rule): Maintain the TZ=value string separately.
749 (syms_of_editfns): Don't initialize initial_tz;
750 init_editfns now does it.
751 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
752 * lisp.h (xputenv): New decl.
754 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

801 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
803 * frame.c (make_frame): Do not set window's buffer to t.
804 * window.c (Fsplit_window_internal): Likewise. Previously it was
805 used to indicate that the window is being set up. Now we use
806 set_window_buffer for all new windows, so the condition in ...
807 (Fset_window_buffer): ... is always true and can be removed.
809 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
811 Convenient macro to check whether the buffer is hidden.
812 * buffer.h (BUFFER_HIDDEN_P): New macro.

819 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
820 if the child process is still running. Instead, exit the wait
821 loop and return zero. (Bug#13086)
823 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
825 * frame.h (x_char_width, x_char_height): Remove prototypes.

838 Fix a recently-introduced delete-process race condition.
839 * callproc.c, process.h (record_kill_process):
840 New function, containing part of the old call_process_kill.
841 (call_process_kill): Use it.
842 This does not change call_process_kill's behavior.
843 * process.c (Fdelete_process): Use record_kill_process to fix a
844 race condition that could cause Emacs to lose track of a child.
846 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
848 Avoid code duplication between prev_frame and next_frame.
849 * frame.c (candidate_frame): New function. Add comment.
850 (prev_frame, next_frame): Use it. Adjust comment.
852 2012-12-06 Eli Zaretskii <eliz@gnu.org>
854 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
855 fails, signal an error instead of continuing with an empty
857 Encode expanded temp file pattern before passing it to mkstemp or
860 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
861 Encode the file name before passing it to dostounix_filename, in
862 case it will downcase it (under w32-downcase-file-names).
865 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
867 Minor call-process cleanups.
868 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
869 at the same time as other platforms, to simplify analysis.
870 No need for fd0_volatile since we have synch_process_fd.
871 Avoid needless emacs_close; arg is always negative.
873 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
875 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
878 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>

882 and mouse_face_hidden members to a bitfields.
883 * frame.h (struct frame): Remove set-but-not-used space_width member.
884 (FRAME_SPACE_WIDTH): Remove.

887 member. Adjust users. Convert term_initted, delete_in_insert_mode,
888 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
889 members to a bitfields.
891 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
893 Don't let call-process be a zombie factory (Bug#12980).
894 Fixing this bug required some cleanup of the signal-handling code.
895 As a side effect, this change also fixes a longstanding rare race
896 condition whereby Emacs could mistakenly kill unrelated processes,
897 and it fixes a bug where a second C-g does not kill a recalcitrant
898 synchronous process in GNU/Linux and similar platforms.
899 The patch should also fix the last vestiges of Bug#9488,
900 a bug which has mostly been fixed on the trunk by other changes.
901 * callproc.c, process.h (synch_process_alive, synch_process_death)
902 (synch_process_termsig, sync_process_retcode):
903 Remove. All uses removed, to simplify analysis and so that
904 less consing is done inside critical sections.
905 * callproc.c (call_process_exited): Remove. All uses replaced
906 with !synch_process_pid.
907 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
908 These take the role of what used to be in unwind-protect arg.
910 (block_child_signal, unblock_child_signal):
911 New functions, to avoid races that could kill innocent-victim processes.
912 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
913 (call_process_kill): Record killed processes as deleted, so that
914 zombies do not clutter up the system. Do this inside a critical
915 section, to avoid a race that would allow the clutter.
916 (call_process_cleanup): Fix code so that the second C-g works again
917 on common platforms such as GNU/Linux.
918 (Fcall_process): Create the child process in a critical section,
919 to fix a race condition. If creating an asynchronous process,
920 record it as deleted so that zombies do not clutter up the system.
921 Do unwind-protect for WINDOWSNT too, as that's simpler in the
922 light of these changes. Omit unnecessary call to emacs_close
923 before failure, as the unwind-protect code does that.
924 * callproc.c (call_process_cleanup):
925 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
926 * process.c (record_deleted_pid): New function, containing
927 code refactored out of Fdelete_process.
928 (Fdelete_process): Use it.
929 (process_status_retrieved): Remove. All callers changed to use
931 (record_child_status_change): Remove, folding its contents into ...
932 (handle_child_signal): ... this signal handler. Now, this
933 function is purely a handler for SIGCHLD, and is not called after
934 a synchronous waitpid returns; the synchronous code is moved to
935 wait_for_termination. There is no need to worry about reaping
936 more than one child now.
937 * sysdep.c (get_child_status, child_status_changed): New functions.
938 (wait_for_termination): Now takes int * status and bool
939 interruptible arguments, too. Do not record child status change;
940 that's now the caller's responsibility. All callers changed.
941 Reimplement in terms of get_child_status.
942 (wait_for_termination_1, interruptible_wait_for_termination):
943 Remove. All callers changed to use wait_for_termination.
944 * syswait.h: Include <stdbool.h>, for bool.
945 (record_child_status_change, interruptible_wait_for_termination):
947 (record_deleted_pid, child_status_changed): New decls.
948 (wait_for_termination): Adjust to API changes noted above.
950 * bytecode.c, lisp.h (Qbytecode): Remove.
951 No longer needed after 2012-11-20 interactive-p changes.
953 2012-12-03 Eli Zaretskii <eliz@gnu.org>
955 * xdisp.c (redisplay_window): If the cursor is visible, but inside
956 the scroll margin, move point outside the margin. (Bug#13055)
958 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
960 * gtkutil.c (my_log_handler): New function.
961 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
963 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
965 * lisp.h (modify_region): Rename to...
966 (modify_region_1): ...new prototype.
967 * textprop.c (modify_region): Now static. Adjust users.
968 * insdel.c (modify_region): Rename to...
969 (modify_region_1): ...new function to work with current buffer.
970 Adjust comment and users. Use true and false for booleans.
972 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
974 * alloc.c (free_save_value): New function.
975 (safe_alloca_unwind): Use it.
976 * lisp.h (free_save_value): New prototype.
977 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
979 (save_excursion_restore): Adjust to match saved data structure.
980 Use free_save_value to offload some work from GC. Drop obsolete
983 2012-12-03 Chong Yidong <cyd@gnu.org>
985 * fileio.c (Vauto_save_list_file_name): Doc fix.
987 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
989 * w32fns.c: Remove prototype of atof.
990 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
992 (file_dialog_callback): Make it UINT_PTR.
994 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
997 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
998 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already

1007 Fix xpalloc confusion after memory is exhausted.
1008 * alloc.c (xpalloc): Comment fix.
1009 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1010 and signals an error, do not clear charset_table_size, as
1011 charset_table is still valid.
1012 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1014 Use execve to avoid need to munge environ (Bug#13054).
1015 * callproc.c (Fcall_process):
1016 * process.c (create_process):
1017 Don't save and restore environ; no longer needed.
1018 * callproc.c (child_setup):
1019 Use execve, not execvp, to preserve environ.
1021 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1023 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1025 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1027 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1028 display for sliced images (Bug#10500).
1030 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1032 2012-11-30 Juanma Barranquero <lekktu@gmail.com>

1035 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1037 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1039 * xdisp.c (window_outdated): Remove eassert since it hits
1040 some suspicious corner cases (see Bug#13007 and Bug#13012).
1041 (mode_line_update_needed): New function.
1042 (redisplay_internal, redisplay_window): Use it.
1043 (ensure_selected_frame): New function.
1044 (redisplay_internal, unwind_redisplay): Use it.
1045 (redisplay_internal): Move comment about buffer_shared...
1046 (buffer_shared_and_changed): ...near to its real use.
1048 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1050 * callproc.c (Fcall_process): Don't misreport vfork failure.
1052 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1054 * callproc.c (Fcall_process): Fix vfork portability problems.
1055 Do not assume that fd[0], count, filefd, and save_environ survive
1056 vfork. Fix bug whereby wrong errno value could be reported for
1057 pipe failure. Some minor cleanups, too, as follows. Move buf and
1058 bufsize to the context where they're needed. Change new_argv to
1059 be of type char **, as this is more convenient and avoids casts.
1060 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1061 Now local constants, not macros.
1063 2012-11-18 Kenichi Handa <handa@gnu.org>
1065 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1066 for the variable "f".
1068 2012-11-13 Kenichi Handa <handa@gnu.org>
1070 * font.c (font_unparse_xlfd): Exclude special characters from the
1071 generating XLFD name.
1073 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

1077 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1079 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1098 violations when repeatedly clicking on the "Top" link of the
1099 "bread-crumbs" in Info buffers.

1109 were always defined.
1111 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1113 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1114 between bpos_covered and bpos_max. This fixes cursor display when
1115 several display strings follow each other.
1117 * .gdbinit (pgx): If the glyph's object is a string, display the
1118 pointer to string data, rather than the value of the string object
1119 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1121 * indent.c (Fvertical_motion): If the starting position is covered
1122 by a display string, return to one position before that, to avoid
1123 overshooting it inside move_it_to. (Bug#12930)
1125 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1127 * frame.h (struct frame): Remove display_preempted member
1128 since all users are dead long ago.

1130 * w32menu.c (pending_menu_activation): Remove since not
1132 (set_frame_menubar): Adjust user.
1133 * w32term.h (struct x_output): Drop outdated #if 0 code.
1134 (struct w32_output): Use bitfields for explicit_parent,
1135 asked_for_visible and menubar_active members.
1136 Drop unused pending_menu_activation member.
1137 * xterm.h (struct x_output): Drop outdated #if 0 code.
1138 Use bitfields for explicit_parent, asked_for_visible,
1139 has_been_visible and net_wm_state_hidden_seen members.
1141 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1143 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1144 of a literal "/". (Bug#12955)
1145 (gl-stamp): Invoke fc.exe directly, not through cmd.
1147 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1149 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1150 * dired.c: Assume HAVE_DIRENT_H.
1151 (NAMLEN): Remove, replacing with ...
1152 (dirent_namelen): New function. All uses changed. Use the GNU macro
1153 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1154 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1155 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1156 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1158 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1159 * ndir.h: Rename to ../nt/inc/dirent.h.
1160 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1161 Do not include <dirent.h>; no longer needed.
1162 * w32.c: Include <dirent.h> rather than "ndir.h".
1164 2012-11-23 Chong Yidong <cyd@gnu.org>
1166 * xftfont.c (xftfont_open): Remove duplicate assignment.
1168 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1170 * alloc.c (Fgarbage_collect): Unblock input after clearing
1171 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1172 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1173 * msdos.c (IT_frame_up_to_date): Use it here...
1174 * w32term.c (w32_frame_up_to_date): ...here...
1175 * xterm.c (XTframe_up_to_date): ...and here...
1176 * nsterm.m (ns_frame_up_to_date): ...but not here.
1177 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1179 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1180 Do not check whether GC is in progress.
1182 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1184 * xdisp.c (window_buffer_changed): New function.
1185 (update_menu_bar, update_tool_bar): Use it to
1186 simplify large 'if' statements.
1187 (redisplay_internal): Generalize commonly used
1188 'tail' and 'frame' local variables.
1190 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1192 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1193 with Windows system header.
1195 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1197 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1198 * alloc.c: Assume unistd.h exists.
1199 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1200 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1201 (getwd) [USG]: Remove; no longer needed.
1202 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1203 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1204 * w32.h (getcwd): Remove decl.
1206 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1208 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1209 Make it set selected_window as well.
1210 (update_tool_bar): Use it.
1212 2012-11-21 Ken Brown <kbrown@cornell.edu>
1214 * emacs.c (main): Set the G_SLICE environment variable for all
1215 Cygwin builds, not just GTK builds. See
1216 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1218 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1220 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1221 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1222 Define for the MSVC compiler.
1224 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1226 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1227 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1228 dostounix_filename. Prevents crashes down the road, because
1229 dostounix_filename assumes it gets a unibyte string.
1230 Reported by Michel de Ruiter <michel@sentient.nl>, see
1231 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

1241 Test NILP rather than Qunbound.
1242 (Ffmakunbound): Set to Qnil.
1243 (Fsymbol_function): Never signal an error.
1244 (Finteractive_form): Ignore Qunbound.
1246 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1248 * eval.c (interactive_p): Remove no-longer-used decl.
1250 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1252 * xdisp.c (buffer_shared): Adjust comment.
1253 (buffer_shared_and_changed): New function.
1254 (prepare_menu_bars, redisplay_internal): Use it to
1255 decide whether all windows or frames should be updated.
1256 (window_outdated): New function.
1257 (text_outside_line_unchanged_p, redisplay_window): Use it.
1258 (redisplay_internal): Likewise. Fix indentation.
1260 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1262 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1263 (syms_of_eval): Remove corresponding defsubr.
1264 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1266 2012-11-19 Daniel Colascione <dancol@dancol.org>
1268 * w32fns.c (Fx_file_dialog):
1269 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1270 cygwin_convert_file_name*.
1272 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1273 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1275 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1277 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1279 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1281 * w32select.c: Include w32common.h before w32term.h, so that
1282 windows.h gets included before w32term.h uses some of its
1283 features, see below.
1285 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1287 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1289 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1291 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1293 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1294 (ns_select): Return at once if events are held (Bug#12834).
1296 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1298 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1299 Needed following 2012-10-20 change. (Bug#12902)
1301 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1303 * w32proc.c (waitpid): Remove unused label get_result.
1305 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1307 * makefile.w32-in (SYSWAIT_H): New macro.
1308 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1309 ($(BLD)/sysdep.$(O)): Update dependencies.
1311 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1313 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1314 * callproc.c (relocate_fd): Assume F_DUPFD.
1315 * emacs.c, term.c (O_RDWR): Remove.
1316 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1317 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1318 * nsterm.m: Assume <fcntl.h> exists.
1319 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1320 (create_pty, Fmake_network_process, server_accept_connection)
1321 (wait_reading_process_output, init_process_emacs):
1323 (wait_reading_process_output): Put in a special case for WINDOWSNT
1324 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1325 It's not clear this is needed, but it's a more-conservative change.
1326 (create_process): Assume FD_CLOEXEC.
1327 (create_process, create_pty): Assume O_NOCTTY.
1328 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1329 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1330 Omit if not DOS_NT, since F_GETFL is not defined there.
1331 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1332 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1334 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1335 lack it, since gnulib guarantees this.
1336 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1338 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1340 * w32.c (faccessat): Pretend that directories have the execute bit
1341 set. Emacs expects that, e.g., in files.el:cd-absolute.
1343 * w32proc.c (create_child): Don't clip the PID of the child
1344 process to fit into an Emacs integer, as this is no longer a
1346 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1347 reaping only the process specified by PID argument, if that is
1348 positive. Use PID instead of dead_child to know which process to
1349 reap. Wait for the child to die only if WNOHANG is not in
1351 (sys_select): Don't set dead_child.
1353 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1354 as it is no longer needed.
1356 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1358 (record_child_status_change): Remove the setting of
1359 record_at_most_one_child for the !WNOHANG case.
1361 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1363 Fix problems in ns port found by static checking.
1364 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1365 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1366 not to process group.
1367 (ns_select): Use emacs_write, not write, as that's more robust
1368 in the presence of signals.
1369 (fd_handler:): Check for read errors.
1371 2012-11-16 Glenn Morris <rgm@gnu.org>
1373 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1375 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1377 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1379 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1381 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1382 use the same value of thread handle.
1383 (start_timer_thread): If the timer thread exited (due to error),
1384 clean up by closing the two handles it used. Duplicate the caller
1385 thread's handle here, so it gets duplicated only once, when
1386 launching the timer thread. Set priority of the timer thread, not
1388 (getitimer): Don't duplicate the caller thread's handle here.
1391 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1393 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1396 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1398 Remove no-longer-used pty_max_bytes variable.
1399 * process.c (pty_max_bytes): Remove; unused.
1400 (send_process): Do not set it.
1402 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1404 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1405 Update dependencies.
1407 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1409 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1410 This follows up on the 2012-09-29 patch that removed indirection
1411 for the 'function' field. Reported by Sergey Vinokurov in
1412 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1414 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1416 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1417 different name, as the MS runtime does not have such a function,
1418 and probably never will.) All callers changed. Ignore DIRFD
1419 value if PATH is an absolute file name, to match Posix spec
1420 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1423 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1425 * xdisp.c (echo_area_display, redisplay_internal):
1426 Omit redundant check whether frame_garbaged is set.
1428 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1430 Use faccessat, not access, when checking file permissions (Bug#12632).
1431 This fixes a bug that has been present in Emacs since its creation.
1432 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1433 which must set some sort of record. (Torek's bug report was against
1434 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1435 same common flaw.) See Torek's Usenet posting
1436 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1437 Posted: Fri Apr 8 14:18:56 1983.

1452 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1453 * fileio.c (check_existing, check_executable, check_writable)
1455 Use symbolic names instead of integers for the flags, as they're
1457 (check_writable): New arg AMODE. All uses changed.
1458 Set errno on failure.
1459 (Ffile_readable_p): Use faccessat, not stat + open + close.
1460 (Ffile_writable_p): No need to call check_existing + check_writable.
1461 Just call check_writable and then look at errno. This saves a syscall.
1462 dir should never be nil; replace an unnecessary runtime check
1463 with an eassert. When checking the parent directory of a nonexistent
1464 file, check that the directory is searchable as well as writable, as
1465 we can't create files in unsearchable directories.
1466 (file_directory_p): New function, which uses 'stat' on most platforms
1467 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1468 (Ffile_directory_p, Fset_file_times): Use it.
1469 (file_accessible_directory_p): New function, which uses a single
1470 syscall for efficiency.
1471 (Ffile_accessible_directory_p): Use it.
1472 * xrdb.c (file_p): Use file_directory_p.
1473 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1474 * lread.c (openp): When opening a file, use fstat rather than
1475 stat, as that avoids a permissions race. When not opening a file,
1476 use file_directory_p rather than stat.
1477 (dir_warning): First arg is now a usage string, not a format.
1478 Use errno. All uses changed.
1479 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1480 that merely introduced a race.
1481 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1482 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1483 and similarly for the other O_* flags.
1484 * w32.c (sys_faccessat): Rename from sys_access and switch to
1485 faccessat's API. All uses changed.
1486 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1487 (magic_db): Rename from magic_file_p.
1488 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1489 char *, so that we don't have to test for file existence
1490 separately from opening the file for reading. This removes a race
1491 fixes a permission-checking problem, and simplifies the code.
1493 (file_p): Remove; no longer needed.
1495 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1497 Omit glyphs initialization at startup.
1498 * dispnew.c (glyphs_initialized_initially_p): Remove.

1503 * xdisp.c (clear_garbaged_frames): Likewise.
1505 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1507 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1508 passed to pint2str and pint2hrstr to be at most the size of the
1509 frame's decode_mode_spec_buffer. This avoids crashes with very
1510 large values of FIELD_WIDTH argument to decode_mode_spec.
1513 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1515 Fix a race with verify-visited-file-modtime (Bug#12863).
1516 Since at least 1991 Emacs has ignored an mtime difference of no
1517 more than one second, but my guess is that this was to work around
1518 file system bugs that were fixed long ago. Since the race is
1519 causing problems now, let's remove that code.
1520 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1521 whose time stamp is off by no more than a second. Insist that the
1522 file time stamps match exactly.
1524 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1526 * frame.h (struct frame): Convert external_tool_bar member to
1527 1-bit unsigned bitfield.

1529 all users are long dead. Adjust comment on mouse_position_hook.
1531 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1533 Simplify by using FOR_EACH_FRAME here and there.
1534 * frame.c (next_frame, prev_frame, other_visible_frames)
1535 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1536 * w32term.c (x_window_to_scroll_bar): Likewise.
1537 * window.c (window_list): Likewise.
1538 * xdisp.c (x_consider_frame_title): Likewise.
1539 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1540 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1541 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1542 * xmenu.c (menubar_id_to_frame): Likewise.
1543 * xselect.c (frame_for_x_selection): Likewise.
1544 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1545 (x_window_to_menu_bar): Likewise.
1546 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1548 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1550 * data.c (Qdefalias_fset_function): Now static.
1552 Another tweak to vectorlike_header change.
1553 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1554 Remove, and replace all uses with ...
1555 (next_in_free_list, set_next_in_free_list):
1556 New functions, which respect C's aliasing rules better.
1558 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1560 * window.c (list4i): Rename from 'quad'. All uses changed.
1561 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1563 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1565 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1566 warning about mixing declarations and code in ISO C90.
1568 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1570 * window.c (Fsplit_window_internal): Set combination limit of
1571 new parent window to t iff Vwindow_combination_limit is t;
1572 fixing a regression introduced with the change from 2012-09-22.
1573 (Fset_window_combination_limit): Fix doc-string.
1575 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1577 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1578 amount when the scroll margins are too large. When scrolling
1579 backwards in the buffer, give up if cannot reach point or the
1580 scroll margin within a reasonable number of screen lines.
1581 Fixes point position in window under scroll-up/down-aggressively when
1582 point is positioned many lines beyond the window top/bottom.
1585 * ralloc.c (relinquish): If real_morecore fails to return memory
1586 to the system, don't crash; instead, leave the last heap
1587 unchanged and return. (Bug#12774)
1589 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1591 * lisp.h (AUTOLOADP): New macro.

1593 * data.c (Ffset): Remove special ad-advice-info handling.
1594 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1596 (Finteractive_form): Simplify.
1597 (Fquo): Don't insist on having at least 2 arguments.
1598 (Qdefalias_fset_function): New var.
1600 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1602 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1604 * nsfont.m (Qcondensed, Qexpanded): New variables.

1606 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1608 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1610 Fix recently introduced crash on MS-Windows (Bug#12839).
1611 * w32term.h (struct scroll_bar): Use convenient header.
1612 (SCROLL_BAR_VEC_SIZE): Remove.
1613 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1615 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1617 Tweak last vectorlike_header change.
1618 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1619 vectorlike object on the free list. This is introduced to avoid
1620 some (but not all) pointer casting and aliasing problems, see
1621 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1622 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1624 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1626 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1628 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1629 been removed, so remove them here also.
1631 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1633 * doc.c (Fdocumentation): Handle new property
1634 dynamic-docstring-function to replace the old ad-advice-info.
1636 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1638 * fns.c (Qeql, hashtest_eq): Now static.
1640 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1642 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1643 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1644 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

1651 * lisp.h (sxhash_combine): New inline function, with the contents
1652 of the old SXHASH_COMBINE.
1653 * profiler.c (hashfn_profiler): Use it, instead of having a
1654 special hash function containing a comparison that always yields 1.
1656 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1658 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1659 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1660 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1663 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1665 * image.c (xpm_make_color_table_h): Fix compiler error because
1666 make_hash_table changed.

1670 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1672 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1674 Use ad-hoc comparison function for the profiler's hash-tables.
1675 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1676 (make_log): Use them.
1677 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1678 call Fequal any more.

1688 (hash_lookup, hash_remove_from_table): Move assertion checking of
1689 hashfn result here. Check hash-equality before calling cmpfn.

1726 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1727 (Fmake_bool_vector): Likewise.
1728 (struct large_vector): New type to represent allocation unit for
1729 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1730 (large_vectors): Change type to struct large_vector.
1731 (allocate_vector_from_block): Simplify.
1732 (PSEUDOVECTOR_NBYTES): Replace with...

1754 * keyboard.c (event_to_kboard): Do not dereference
1755 frame_or_window field of SELECTION_REQUEST_EVENT

1759 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1761 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1762 such as Scroll Lock, if the respective keys are treated as
1763 function keys, not as modifiers. This avoids destroying non-ASCII
1764 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1766 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1768 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1770 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1772 Restore some duplicate definitions (Bug#12814).
1773 This undoes part of the 2012-11-03 changes. Some people build
1774 with plain -g rather than with -g3, and they need the duplicate
1775 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1776 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1777 Define as macros, as well as as enums or as constants.

1781 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1782 to keypad keys (Bug#12816).
1784 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1786 Minor adjustments of recently-changed frame functions.
1787 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1788 known to be a frame (we're in the FRAMEP branch).
1789 * lisp.h (Qframep): Remove decl. frame.h declares this.
1790 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1791 since they're meant for Lisp fixnum values.
1793 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1795 * window.c (Fwindow_combination_limit): Revert to the only
1796 required argument and adjust docstring as suggested in
1797 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1798 by Martin Rudalics <rudalics@gmx.at>.

1844 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1845 (Fwindow_combination_limit): Allow zero number of arguments.
1847 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1849 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1851 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1852 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1853 file descriptor 2 for standard error. (Bug#12805)
1855 2012-11-05 Chong Yidong <cyd@gnu.org>
1857 * process.c (wait_reading_process_output): Revert previous change.
1859 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1861 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1862 This removes code that has been obsolete since around 1990.
1863 * callproc.c (Fcall_process):
1865 * process.c (create_process):
1866 * term.c (dissociate_if_controlling_tty):
1867 Assume setsid exists.
1868 * callproc.c (child_setup): Assume setpgid exists and behaves as

1870 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1871 * emacs.c (shut_down_emacs):
1872 * sysdep.c (sys_suspend, init_foreground_group):
1873 Assume getpgrp behaves as per POSIX.1-1998 or later.

1882 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1883 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1884 Do not assume that __fpending's result fits in int.
1886 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1888 Remove EMACS_OUTQSIZE+sleep hack.
1889 * dispnew.c (update_frame_1): Remove hack for terminals slower
1890 than 2400 bps, which throttled Emacs by having it sleep.
1891 This code hasn't worked since at least 2007, when the multi-tty stuff
1892 was added, and anyway those old terminals are long dead.
1893 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1894 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1896 Fix data-loss with --version (Bug#9574).
1897 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1898 as we can't assume that emacs_strerror is initialized, and strerror
1899 is good enough here.
1900 (main): Invoke atexit earlier, to catch earlier instances of
1901 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1903 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1905 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1906 (keyDown): Remap keypad keys to X11 virtual key codes.
1908 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1910 Fix data-loss with --batch (Bug#9574).
1911 * emacs.c: Include <close-stream.h>.
1912 (close_output_streams): New function.
1913 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1914 and handles errors appropriately.
1915 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1918 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1919 The symptom is a diagnostic "GLib-WARNING **: In call to
1920 g_spawn_sync(), exit status of a child process was requested but
1921 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1922 waitpid(), so exit status can't be returned." The diagnostic
1923 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1924 The real bug is a race condition between Emacs and glib: Emacs
1925 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1926 so that glib can't find it. Work around the bug by invoking
1927 waitpid only on subprocesses that Emacs itself creates.
1928 * process.c (create_process, record_child_status_change):
1929 Don't use special value -1 in pid field, as the caller now must
1930 know the pid rather than having the callee infer it.
1931 The inference was sometimes incorrect anyway, due to another race.
1932 (create_process): Set new 'alive' member if child is created.
1933 (process_status_retrieved): New function.
1934 (record_child_status_change): Use it.
1935 Accept negative 1st argument, which means to wait for the
1936 processes that Emacs already knows about. Move special-case code
1937 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1938 processes that have already been waited for, by testing and
1939 clearing new 'alive' member.
1940 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1941 now does this internally.
1942 (handle_child_signal): Let record_child_status_change do all
1943 the work, since we do not want to reap all exited child processes,
1944 only the child processes that Emacs itself created.
1945 * process.h (Lisp_Process): New boolean member 'alive'.
1947 Omit duplicate definitions no longer needed with gcc -g3.
1948 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1949 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1950 Define only as macros. There's no longer any need to also define
1951 these symbols as enums or as constants, since we now assume
1952 gcc -g3 when debugging.
1954 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1956 * lisp.mk: Adjust comments to the fact that term/internal is now
1957 loaded from loadup.el.
1959 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1960 (msdos_fatal_signal): New function.
1961 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1964 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1965 for GCC versions before 4.
1966 (emacs_raise): Define to call msdos_fatal_signal.
1968 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1969 iterator when starting in the middle of a display or overlay
1972 2012-11-03 Chong Yidong <cyd@gnu.org>
1974 * process.c (wait_reading_process_output): Clean up the last
1977 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1979 * process.c (wait_reading_process_output): Avoid a race condition
1980 with SIGIO delivery (Bug#11536).
1982 2012-11-03 Chong Yidong <cyd@gnu.org>
1984 * buffer.c (cursor_type): Untabify docstring.
1986 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1988 * frame.h (struct frame): Drop can_have_scroll_bars member
1989 which is meaningless for a long time. Adjust comments.
1990 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1991 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1993 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1995 * window.c (decode_next_window_args): Update window arg after
1996 calling decode_live_window and so fix crash reported at
1997 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1998 by Juanma Barranquero <lekktu@gmail.com>.
1999 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2000 * font.c (Ffont_at): Likewise.
2002 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2004 * widget.c (resize_cb): New function.
2005 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2006 (EmacsFrameResize): Check if all is up to date before changing frame
2009 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2011 Implement backtrace output for fatal errors on MS-Windows.
2012 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2013 (BACKTRACE_LIMIT_MAX): New macro.
2014 (w32_backtrace): New function.
2015 (emacs_abort): Use w32_backtrace when the user chooses not to
2016 attach a debugger. Update the text of the abort dialog.
2018 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2020 Window-related stuff cleanup here and there.
2021 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2022 Use decode_any_window.
2023 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2024 * xdisp.c (Fformat_mode_line): Likewise.
2025 * font.c (Ffont_at): Use decode_live_window.
2026 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2027 * window.c (decode_next_window_args): Likewise.
2028 (decode_any_window): Remove static.
2029 * window.h (decode_any_window): Add prototype.
2030 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2031 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2034 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2036 Remove pad from struct input_event.
2037 * termhooks.h (struct input_event): Remove padding field.
2039 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2040 member is never cons for a long time. Adjust comment.
2041 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2042 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2043 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2044 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2046 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2048 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2050 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2052 Fix crash when using Emacs as commit editor for git (Bug#12697).
2053 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2054 and it is configured in conf_post.h.
2055 (Fcall_process): Don't invoke both setsid and setpgid; the former
2056 is enough, if it exists.
2057 * callproc.c (Fcall_process, child_setup):
2058 * process.c (create_process): Use setpgid.
2059 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2061 * dispnew.c (init_display): Initialize the foreground group
2062 if we are running a tty display.
2063 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2064 * lisp.h (init_foreground_group): New decl.
2065 * sysdep.c (inherited_pgroup): New static var.
2066 (init_foreground_group, tcsetpgrp_without_stopping)
2067 (narrow_foreground_group, widen_foreground_group): New functions.
2068 (init_sys_modes): Narrow foreground group.
2069 (reset_sys_modes): Widen foreground group.
2071 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2073 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2075 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2077 * minibuf.c (read_minibuf): Restore current buffer since
2078 choose_minibuf_frame calling Fset_frame_selected_window may
2079 change it (Bug#12766).
2081 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2083 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2085 2012-10-30 Kenichi Handa <handa@gnu.org>
2087 * font.c (Ffont_at): If WINDOW is specified and it is not
2088 displaying the current buffer, signal an error.
2090 2012-10-29 Daniel Colascione <dancol@dancol.org>
2092 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2093 In preparation for fixing bug#12739, move these functions from
2096 * coding.h, coding.c: ... to here, and compile them only when
2097 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2098 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2100 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2102 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2103 (timer_loop, getitimer, setitimer): Use it instead of
2104 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2106 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2109 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2111 * nsterm.m (NO_APPDEFINED_DATA): New define.
2112 (last_appdefined_event_data): New variable
2113 (last_appdefined_event): Remove.
2114 (ns_select): Initialize t from last_appdefined_event_data instead
2115 of [last_appdefined_event data1].
2116 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2117 remove last_appdefined_event (Bug#12698).
2119 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2121 * frame.c (x_set_font): Catch internal error.
2123 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2125 Avoid overflow in w32 implementation of interval timers.
2126 When possible, for ITIMER_PROF count only times the main thread
2128 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2129 'volatile ULONGLONG' types. All the other data which was
2130 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2131 (GetThreadTimes_Proc): New typedef.
2132 (w32_get_timer_time): New function, returns a suitable time value
2134 (timer_loop): Enter critical section when accessing ULONGLONG
2135 values of the itimer_data struct, as these accesses are no longer
2136 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2137 Remove unused variable.
2138 (init_timers): Initialize s_pfn_Get_Thread_Times.
2139 (start_timer_thread): Don't assign itimer->caller_thread here.
2140 (getitimer): Assign itimer->caller_thread here.
2141 (setitimer): Always call getitimer to get the value of ticks_now.
2142 (sys_spawnve): Avoid compiler warning about format mismatch.
2144 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2146 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2147 mouse movement events if the menu bar is active. This avoids
2148 producing a busy "hour-glass" cursor by Windows if the mouse
2149 pointer is positioned over a tooltip shown for some menu item.
2151 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2153 Don't assume process IDs fit in int.
2154 * emacs.c (shut_down_emacs) [!DOS_NT]:
2155 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2156 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2157 Use pid_t, not int, to store process IDs, as 'int'
2158 is not wide enough on a few platforms (e.g., AIX and IRIX).
2160 2012-10-23 Kenichi Handa <handa@gnu.org>
2162 The following change is to make face-font-rescale-alist work
2163 correctly for non-ASCII fonts.
2165 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2166 (font_open_for_lface): Handle Vface_font_rescale_alist.
2168 2012-10-23 Chong Yidong <cyd@gnu.org>
2170 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2172 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2174 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2176 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2178 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2181 2012-10-21 Glenn Morris <rgm@gnu.org>
2183 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2185 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2187 Port to OpenBSD 5.1.
2188 * frame.c (Fmouse_position, Fmouse_pixel_position):
2189 * xdisp.c (produce_stretch_glyph):
2190 Declare local vars only when they're needed.
2191 This is clearer and avoids a warning on OpenBSD about unused vars.
2192 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2193 This is safer, and avoids OpenBSD warnings about unused vars.
2194 * keyboard.c (record_menu_key): Remove unnecessary decl.
2195 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2196 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2197 as our definition clashes with OpenBSD's.
2198 * xfaces.c (load_face_colors, check_lface_attrs)
2199 (get_lface_attributes_no_remap, get_lface_attributes)
2200 (lface_fully_specified_p, x_supports_face_attributes_p)
2201 (tty_supports_face_attributes_p, face_fontset, realize_face)
2202 (realize_x_face, realize_tty_face):
2203 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2204 merely Lisp_Object *. This is more informative and avoids
2205 a warning on OpenBSD about accessing beyond an object's size.
2207 2012-10-20 Chong Yidong <cyd@gnu.org>
2209 * lread.c (Fload): Doc fix (Bug#12592).
2211 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2213 * font.c (Ffont_at): Fix previous change.
2215 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2217 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2218 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2221 * alloc.c (NSTATICS): Decrease to 0x800.
2223 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

2228 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2230 * nsterm.m (ns_select): Check writefds before call to
2231 FD_ISSET (Bug#12668).
2233 2012-10-18 Daniel Colascione <dancol@dancol.org>
2235 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2236 (staticpro): If we run out of staticpro slots, die with an
2237 informative error instead of just calling emacs_abort.
2239 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2241 Fix two flaws reported by Dmitry Antipov.
2242 * window.c (Ftemp_output_buffer_show): Remove.
2243 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
2244 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.

2262 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
2263 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
2264 (sys_link): Add prototypes.
2266 * w32.c: Include w32select.h.
2267 (sys_access, e_malloc, sys_select): Add prototypes.
2268 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
2270 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
2272 * unexw32.c: Include lisp.h and w32.h.
2274 * term.c [WINDOWSNT]: Include w32term.h.
2276 * process.c [WINDOWSNT]: Add prototype of sys_select.
2278 * fileio.c [WINDOWSNT]: Include w32.h.
2280 * dispnew.c [WINDOWSNT]: Include w32.h.
2282 * cygw32.c (Fcygwin_convert_path_to_windows)
2283 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
2284 Lisp_Object values. (Bug#12661)
2286 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
2287 to Lisp_Object. (Bug#12661)
2289 2012-10-17 Kenichi Handa <handa@gnu.org>

2299 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
2301 Do not verify indirection counters of killed buffers (Bug#12579).
2302 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
2303 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.

2307 * alloc.c (Fmake_byte_code): Fix typo in comment.
2308 * print.c (print_interval): Define as static to match prototype.
2309 * indent.c (disptab_matches_widthtab, recompute_width_table):

2323 2012-10-15 Martin Rudalics <rudalics@gmx.at>
2325 * window.c (Fwindow_end): Rewrite check whether cached position
2326 can be used (Bug#12600).

2328 Set windows_or_buffers_changed.
2330 2012-10-15 Daniel Colascione <dancol@dancol.org>
2332 * dbusbind.c: Fix cygw32 build break when compiling with dbus
2333 enabled by undefining the symbol "interface", which the platform
2334 headers define to something incompatible.
2336 2012-10-14 Daniel Colascione <dancol@dancol.org>
2338 * image.c (init_tiff_functions, init_imagemagick_functions)

2348 * gtkutil.c (xg_set_widget_bg): Divide by 65535 (Bug#12612).
2350 2012-10-13 HANATAKA, Shinya <bogytech@gmail.com> (tiny change)

2355 2012-10-13 Andreas Schwab <schwab@linux-m68k.org>
2357 * fileio.c: Formatting fixes.
2359 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
2361 Fix some stat-related races.
2362 * fileio.c (Fwrite_region): Avoid race condition if a file is
2363 removed or renamed by some other process immediately after Emacs
2364 writes it but before Emacs stats it. Do not assume that stat (or
2366 * image.c (slurp_file): Resolve the file name with fopen + fstat
2367 rather than stat + fopen.
2368 (pbm_read_file) [0]: Remove unused code with stat race.
2369 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:
2370 Remove ineffective code with stat race.
2372 2012-10-12 Stefan Monnier <monnier@iro.umontreal.ca>

2385 is zero (Bug#12384).
2387 2012-10-12 Juanma Barranquero <lekktu@gmail.com>

2393 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
2395 * fileio.c (check_existing): New function.
2396 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
2397 instead of calling 'stat', when what's needed is to check whether
2398 a file exists. This avoids expensive system calls on MS-Windows.
2401 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
2403 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
2404 determine whether a file exists and is not a directory.
2406 * lisp.h (check_existing): Add prototype.
2408 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
2410 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

2440 Use bool for booleans.
2441 * lread.c (safe_to_load_version): Rename from safe_to_load_p,

2450 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
2452 * marker.c (cached_modiff): EMACS_INT, not int.
2454 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
2455 instead of having a wrong decl.

2493 (detect_input_pending_run_timers):
2494 * process.c (wait_reading_process_output):
2495 Use unsigned for counter where wraparound-on-overflow is desired,
2496 since unsigned is guaranteed to have that behavior and signed is not.
2497 (read_char): Use ptrdiff_t for string length.
2498 (get_input_pending): Remove first argument, since it was always
2499 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2500 and behave as if it had that value. Return new value of
2501 input_pending. All callers changed.
2502 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2503 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
2505 * keymap.c (push_key_description): Omit last arg, which was always 1.
2506 All callers changed.
2508 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
2510 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

2526 Don't include termopts.h.
2528 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
2530 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
2532 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2534 * commands.h (immediate_quit): Remove duplicate decl.
2536 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
2538 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
2540 (nsfont_open): Remove setting of Vfonts_in_cache.
2541 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
2543 2012-10-09 Eli Zaretskii <eliz@gnu.org>
2545 * w32fns.c (w32_last_error): Change the return value to DWORD, to
2546 match what GetLastError returns. Explain why the function is
2549 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2550 'is_tooltip_frame', to avoid confusion with its global namesake.
2552 2012-10-08 Daniel Colascione <dancol@dancol.org>
2554 * xdisp.c (start_hourglass): Call w32_note_current_window when
2555 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2556 build that caused Emacs to display the hourglass cursor forever.
2558 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2559 which is broken under remote desktop, calculate the number of
2560 colors available for a display based on the display's number of
2561 planes and number of bits per pixel per plane. (bug#10397).
2563 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2565 * nsfont.m (Vfonts_in_cache): New variable.
2566 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2567 are used. Add cached fonts to Vfonts_in_cache.
2568 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2570 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2572 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2574 (FONT_H): Define after FRAME_H.
2575 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2576 Update dependencies.
2578 * w32term.c: Remove leftover declaration of keyboard_codepage.
2580 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2582 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2583 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2584 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2585 (GLOBAL_SOURCES): Add cygw32.c.
2586 ($(BLD)/unexw32.$(O)):
2588 ($(BLD)/w32console.$(O)):
2589 ($(BLD)/w32fns.$(O)):
2590 ($(BLD)/w32heap.$(O)):
2591 ($(BLD)/w32menu.$(O)):
2592 ($(BLD)/w32proc.$(O)): Add w32common.h.
2594 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2596 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2598 2012-10-08 Daniel Colascione <dancol@dancol.org>
2600 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2601 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2602 accidental message numbering hole. Change other messages to
2605 * w32select.h (HAVE_W32SELECT): Remove.
2607 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2608 w32common.h instead of w32heap.h.
2610 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2611 (get_allocation_unit, get_processor_type, get_w32_major_version)
2612 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2613 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2614 (OS_NT, os_subtype, cache_system_info): Move declarations to
2617 * w32heap.c: Include w32common.h.
2618 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2619 (w32_minor_version, w32_build_number, w32_subtype):
2620 Remove duplicate definitions.
2622 * w32fns.c: Include w32common.h; include w32heap.h only in
2625 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2626 Use `report_file_error' instead of `error' in order to better
2627 inform users of what went wrong. Increase NTGUI_UNICODE file
2628 dialog box file name length to 32k, the maximum allowed by the NT
2631 * w32common.h: New file.
2632 (ROUND_UP, ROUND_DOWN, get_page_size)
2633 (get_allocation_unit, get_processor_type, get_w32_major_version)
2634 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2635 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2636 (OS_NT, os_subtype, cache_system_info): Move here.
2638 * unexw32.c, unexcw.c: Include w32common.h.
2640 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2641 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2642 to call syms_of_w32select.
2644 * cygw32.h: Remove obsolete EXFUN declarations.
2646 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2648 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2649 of w32inevt.o from SOME_MACHINE_OBJECTS.
2651 2012-10-08 Daniel Colascione <dancol@dancol.org>
2653 * image.c: Permanent fix for JPEG compilation issue --- limit
2654 jpeglib `boolean' redefinition to Cygwin builds.
2656 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2658 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2660 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2663 2012-10-08 Daniel Colascione <dancol@dancol.org>
2665 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2666 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2667 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2668 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2669 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2670 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2671 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2672 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2673 now a supported configuration.
2675 * Makefile.in: consolidate image variables into LIBIMAGE; add
2676 W32_OBJ and W32_LIBS. Compile new files.
2679 (_DebPrint) declare tracing facility for W32 debugging. We need
2680 to unify tracing later.
2682 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2683 unconditional use of W32 Unicode functions. Cygwin runs only on
2684 100% Unicode operating systems.
2686 * cygw32.c: New file. Define Cygwin-specific facilities.
2687 (Fcygwin_convert_path_to_windows)
2688 (Fcygwin_convert_path_from_windows): New user functions for
2689 accessing Cygwin path-munging routines.
2691 * cygw32.h: New file.
2692 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2693 UTF-16LE strings temporarily inside non-Lisp-visible string
2696 (w32_strerror): Just what it says on the tin.
2698 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2699 also run for Cygwin; both systems have the same problem with using
2700 GUI facilities in a forked child. Also call syms_of_cygw32,
2701 syms_of_w32select in correct places.
2703 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2704 needs fork-then-exec for daemon launching.
2706 * font.h: Include frame.h.
2708 * image.c: Use the image library cache machinery only when we're
2709 compiling for native WINDOWSNT; Cygwin can use shared libraries
2710 like any other Unixlike system.
2712 * keyboard.c: Clarify a comment regarding the input loop.
2714 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2715 functions directly instead of trying to detect at runtime that our
2716 host operating system supports them. We make this change for two
2717 reasons: Cygwin lacks support for the multibyte character
2718 conversion functions used by the legacy menu code, and Cygwin
2719 never needs to rely on non-Unicode APIs.
2721 * unexw32.c (hinst): Declare extern.
2723 * w32.c: Change header order;
2724 (w32_strerror): Move to w32fns.c because we need it for
2725 non-WINDOWSNT builds.
2727 * w32.h: Add #error macro to make sure we don't include w32.h for
2728 Cygwin builds. Remove w32select declarations.
2730 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2731 w32fns.c. w32console.c is WINDOWSNT-only.
2733 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2734 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2736 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2737 (w32_major_version, w32_minor_version, w32_build_number)
2738 (os_subtype, sound_type): Define here
2739 (w32_defined_color): Make color parameter const for consistency
2740 with other _defined_color functions.
2741 (w32_createwindow): Unconditionally call w32_init_class instead of
2742 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2743 through the code is complex and unnecessary because class
2744 registration is practically free.
2745 (w32_name_of_message): New EMACSDEBUG-only function.
2746 (Fset_message_beep): Move here
2747 (Fx_open_connection): Require that the display name for Windows be
2748 "w32" for consistency, emacsclient disambiguation, and maybe, one
2749 day, multi-window-system support.
2750 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2751 Cygwin files for W32 GUI facilities, since these clearly don't
2752 expect Cygwin names.
2753 (_DebPrint): Define.
2754 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2755 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2756 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2757 (w32_last_error): Remove.
2759 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2761 * w32heap.c (syspage_mask): Declare here.
2762 (cache_system_info): Remove.
2764 * w32inevt.c (faked_key): Define globally, not statically.
2765 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2766 (w32_console_toggle_lock_key): Move to w32fns.c.
2768 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2770 * w32proc.c (_DebPrint): Move to w32fns.c.
2771 * w32select.c: Include string.h, stdio.h for Cygwin.
2772 * w32select.h: New File.
2774 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2776 (w32_message_fd): New variable. Under Cygwin, holds the file
2777 descriptor the system used to tell us about pending thread
2780 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2781 that prevented compilation under non-WINDOWSNT systems.
2783 (w32_initialize): Open /dev/windows and assign it to
2784 w32_message_fd. Provide w32 feature.
2786 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2787 (WM_EMACS_INPUT_READY): add.
2788 (prepend_msg, w32_message_fd): Declare globally.
2791 (keyboard_handle): Use only when WINDOWSNT.
2792 (notify_msg_ready): New function. Posts a message to the main
2793 thread's message queue under CYGWIN, which wakes up the main
2794 thread from select(2) by making the /dev/windows file descriptor
2795 ready. Under WINDOWSNT, it sets an event the same way the old
2798 (post, prepend_msg): Actually call notify_msg_ready instead of
2799 setting the input event directly.
2801 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2803 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2804 but it still has blocs in it, don't return it to the system,
2805 instead of aborting. (Bug#12402)
2807 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2809 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2811 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2812 MAC_OS_X_VERSION_10_6.
2813 (syms_of_nsterm): Remove comment about Panther and above for
2815 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2816 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2817 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2819 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2820 MAC_OS_X_VERSION_10_4.
2822 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2823 MAC_OS_X_VERSION_10_2.
2825 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2827 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2828 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.

2840 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2842 Improve sys_siglist detection.
2843 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2844 defined as a macro, as is done in Solaris.
2845 (sys_siglist_entries): New macro.
2846 (save_strsignal): Use it.
2847 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2848 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2850 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2852 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2853 fullscreen/Fullscreen.
2855 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2856 tobar_height is new.
2858 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2859 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2860 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2861 (windowDidResize:): Check for correct window if old style fullscreen.
2862 Capitalize word in comment. Remove incorrect comment.
2863 (initFrameFromEmacs:): tbar_height renamed tibar_height.

2873 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2875 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2877 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2879 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2880 that time stamps of directories could also be changed.
2881 Don't request the too broad GENERIC_WRITE, only the more restrictive
2882 FILE_WRITE_ATTRIBUTES access rights.
2884 * fileio.c (Fset_file_times): Special-case ignoring errors for
2885 directories only on MSDOS, not on MS-Windows.
2887 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2889 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2891 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2893 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2894 see whether CreateFile failed.
2896 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2898 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2899 to avoid similar races.
2900 * keyboard.c (pending_signals): Now bool, not int.
2902 Port timers to OpenBSD, plus check for timer failures.
2903 OpenBSD problem reported by Han Boetes.
2904 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2906 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2907 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2908 like OpenBSD, which has timer_settime but does not declare it.
2909 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2910 whether to use itimerspec-related primitives. All uses of
2911 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2913 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2915 * profiler.c (handle_profiler_signal): Fix a malloc race
2916 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2918 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2920 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2922 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2924 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2925 consistent with the change in return value of 'safe_strsignal'.
2927 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2929 Prefer plain 'static' to 'static inline' (Bug#12541).
2930 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2931 (bidi_set_sor_type, bidi_push_embedding_level)
2932 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

2937 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2938 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2939 Now 'static', not 'static inline'.
2941 Count overruns when profiling; change units to ns.
2942 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2943 Give extra weight to samples after overruns, to attempt to count
2944 the time more accurately.
2945 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2946 the underlying primitives nominally do ns.
2947 (Fprofiler_cpu_start): Document the change. Mention that
2948 the sampling intervals are only approximate.
2950 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2952 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2954 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2955 case for the special 0 coding-system.
2957 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2958 (Fmake_overlay): Remove redundant tests.
2959 (fix_start_end_in_overlays): Remove redundant recentering.
2961 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2963 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2964 Update dependencies.
2966 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2968 Fix a malloc race condition involving strsignal.
2969 A signal can arrive in the middle of a malloc, and Emacs's signal
2970 handler can invoke strsignal, which can invoke malloc, which is
2971 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2972 Fix it by altering the signal handler so that it does not invoke
2974 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2975 * process.c (status_message): Use const pointer, in case strsignal
2976 is #defined to safe_strsignal.
2977 * sysdep.c (sys_siglist, init_signals): Always define and
2978 initialize a substitute sys_siglist if the system does not define
2979 one, even if HAVE_STRSIGNAL.
2980 (safe_strsignal): Rename from strsignal. Always define,
2981 using sys_siglist. Return a const pointer.
2982 * syssignal.h (safe_strsignal): New decl.
2983 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2985 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2987 * w32proc.c (timer_loop): Fix code that waits for timer
2988 expiration, to avoid high CPU usage.
2990 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2992 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2993 (sweep_weak_table): Remove redundant prototypes.
2995 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2997 * emacs.c: Move the inclusion of TERM_HEADER after including
2998 windows.h on WINDOWSNT. This avoids compilation problems with
3001 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3003 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3004 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3005 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3006 as the previous version used 'void *'.
3008 * ralloc.c (ROUNDUP): Fix last change.
3009 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3012 * w32proc.c <disable_itimers>: New static flag.
3013 (init_timers): Initialize it to zero, after creating the critical
3014 sections used by the timer threads.
3015 (term_timers): Set to 1 before deleting the critical sections.
3016 (getitimer, setitimer): If disable_itimers is non-zero, return an
3017 error indication without doing anything. Reported by Fabrice
3018 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3019 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3021 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3024 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3025 term_ntproc after all the other bookkeeping, to get timers working
3026 as long as possible.
3028 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3030 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3031 Suggested by Juri Linkov in
3032 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3034 Prefer plain 'static' to 'static inline' (Bug#12541).
3035 With static functions, modern compilers inline pretty well by
3036 themselves; advice from programmers often hurts as much as it helps.
3037 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3038 this change shrinks the text size of the Emacs executable by 1.1%
3039 without affecting CPU significantly in my benchmark.
3040 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3120 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3122 Revert the FOLLOW-SYMLINKS change for file-attributes.
3123 Doing it right would require several changes to Tramp, and there's
3124 not enough time to get that tested before the freeze today.
3125 * dired.c (directory_files_internal, Ffile_attributes):
3128 * frame.c (x_report_frame_params): Port better to wider ints.
3129 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3130 or that pointers can be printed in 15 decimal digits.
3131 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3168 (check_memory_limits): Adjust prototypes of real_morecore and
3169 __morecore to receive argument of type ptrdiff_t. Use size_t for

3241 to hourglass timer expiration.
3242 (start_hourglass, cancel_hourglass, DEFAULT_HOURGLASS_DELAY):
3243 Remove, no longer used.
3244 (w32_note_current_window, show_hourglass, hide_hourglass):

3249 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
3251 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
3253 * w32.h (init_timers, term_timers): Add prototypes.
3255 2012-09-30 Kenichi Handa <handa@gnu.org>
3257 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
3258 to the buffer relocation which may be caused by ccl_driver.

3276 (windowDidExitFullScreen, toggleFullScreen, handleFS)
3277 (setFSValue): New functions.
3278 (EmacsFSWindow): New implementation.

3289 fullscreen. Set maximized_width/height. Act on next_maximized.
3291 * nsterm.h (MAC_OS_X_VERSION_10_7, MAC_OS_X_VERSION_10_8): New.
3292 (EmacsView): Add variables for fullscreen.
3293 (handleFS, setFSValue, toggleFullScreen): New in EmacsView.
3294 (EmacsFSWindow): New interface for fullscreen.
3296 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
3298 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
3300 2012-09-30 Chong Yidong <cyd@gnu.org>
3302 * fns.c (Frandom): Doc fix.
3304 2012-09-30 Martin Rudalics <rudalics@gmx.at>
3306 * window.c (Vwindow_combination_limit): New default value.
3307 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
3309 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
3311 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
3312 Suggested by Eli Zaretskii in
3313 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
3315 2012-09-30 Eli Zaretskii <eliz@gnu.org>
3317 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
3318 HAVE_TIMER_SETTIME is defined.
3320 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
3322 Profiler improvements: more-accurate timers, overflow checks.
3323 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3324 signal.h, setjmp.h. Include systime.h instead.
3325 (saturated_add): New function.
3326 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
3327 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
3328 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
3330 (enum profiler_cpu_running): New enum.
3331 (profiler_cpu_running): Now of that enum type, not bool.
3332 All uses changed to store the new value.
3333 (handle_profiler_signal): Rename from sigprof_handler_1,
3334 for consistency with other handlers. Do not check whether
3335 cpu_log is a hash-table if garbage collecting, since it
3336 doesn't matter in that case.
3337 (deliver_profiler_signal): Rename from sigprof_handler,
3338 for consistency with other handlers.
3339 (setup_cpu_timer): New function, with much of what used to be in
3340 Fprofiler_cpu_start. Check for out-of-range argument.
3341 Prefer timer_settime if available, and prefer
3342 thread cputime clocks, then process cputime clocks, then
3343 monotonic clocks, to the old realtime clock. Use make_timeval
3344 to round more-correctly when falling back to setitimer.
3345 (Fprofiler_cpu_start): Use it.
3346 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3347 Don't assume that passing NULL as the 2nd argument of setitimer
3348 is the same as passing a pointer to all-zero storage.
3349 Ignore SIGPROF afterwards.
3350 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3351 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3352 non-fatal signal handlers. Ignore SIGPROF on startup.
3353 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3354 in profiler.c, since sysdep.c now uses it.
3356 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
3357 Suggested by Eli Zaretskii in
3358 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

3373 2012-09-28 Glenn Morris <rgm@gnu.org>
3375 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
3376 (Frun_hook_with_args_until_failure): Doc fixes.
3378 2012-09-28 Eli Zaretskii <eliz@gnu.org>
3380 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
3381 Qautomatic_redisplay and change the symbol name. All users changed.
3383 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>

3408 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
3410 * character.h (MAYBE_UNIFY_CHAR): Remove.
3411 * charset.c, charset.h (maybe_unify_char): Now static.
3412 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3413 Since this stuff is now private to charset.c, there's no need for
3414 a public macro and no need to inline by hand.
3416 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
3417 Stefan Monnier <monnier@iro.umontreal.ca>

3447 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
3449 Prefer POSIX timers if available.
3450 They avoid a race if the timer is too close to the current time.
3451 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
3452 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
3453 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
3455 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3457 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
3458 CHAR_STRING_ADVANCE.
3459 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
3460 STRING_CHAR_ADVANCE.

3478 * w32.h (Vlibrary_cache): Do not declare.
3480 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3482 * w32proc.c (sys_signal): Handle all signals defined by the
3483 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3484 handlers for signals supported by Windows. Don't override
3485 term_ntproc as the handler for SIGABRT.
3486 (sigaction): Rewrite to call sys_signal instead of duplicating its
3488 (sys_kill): Improve commentary.
3490 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3491 consistency with a signature of a signal handler. All callers
3493 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3494 install term_ntproc as a signal handler for SIGABRT, as that
3495 should be done by the dumped Emacs.
3497 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3499 * w32select.c (term_w32select): Protect against repeated
3500 invocation by setting clipboard_owner to NULL after calling
3503 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
3504 and term_ntproc to their modified signatures.
3506 * character.c (char_string, string_char): Remove calls to
3507 MAYBE_UNIFY_CHAR. See the discussion starting at

3511 2012-09-25 Chong Yidong <cyd@gnu.org>
3513 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
3515 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
3517 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
3518 when encountering an unknown bytecode.
3520 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3522 image.c, indent.c: Use bool for booleans.
3523 * dispextern.h (struct image_type): Members valid_p, load, init

3525 * image.c: Omit unnecessary static decls.
3526 (x_create_bitmap_mask, x_build_heuristic_mask):
3527 Return void, not int, since callers don't care about the return value.

3564 Move pid_t related decls out of lisp.h.
3565 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3566 (interruptible_wait_for_termination):
3567 Move these decls from lisp.h to syswait.h, since they use pid_t.
3568 Needed on FreeBSD; see Herbert J. Skuhra in
3569 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3570 * callproc.c: Include syswait.h.

3616 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3618 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3619 fatal_error_backtrace.
3621 * w32proc.c (sys_kill): Undo last change: don't do anything when
3622 invoked to deliver SIGABRT to our own process. This is now
3623 handled by emacs_raise.
3625 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3627 * w32term.c (w32_read_socket): Remove leftover reference to
3628 interrupt_input_pending.
3630 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3632 Do not use SA_NODEFER.
3633 Problem reported by Dani Moncayo in
3634 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3636 * sysdep.c (emacs_abort): Do not reset signal handler.
3637 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3638 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3639 wanted even on POSIXish hosts, and it doesn't work on Windows.
3641 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3643 * xterm.c (x_term_init): Call fixup_locale before and after calling
3644 gtk_init (Bug#12392).
3646 2012-09-23 Chong Yidong <cyd@gnu.org>
3648 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3649 Vdynamic_library_alist.
3651 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3652 (Fgnutls_available_p): Caller changed.
3654 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3655 (Flibxml_parse_xml_region): Likewise.
3657 * dispextern.h (struct image_type): Remove arg from init function.
3659 * image.c (Finit_image_library, lookup_image_type)
3660 (define_image_type): Remove now-unneeded second arg.
3661 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3662 (init_tiff_functions, init_gif_functions, init_svg_functions):
3663 Arglist and w32_delayed_load calling convention changed.
3664 (gs_type): Remove init_gs_functions; there is no such function.
3665 (valid_image_p, make_image): Fix caller to lookup_image_type.
3667 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3669 Simplify and avoid signal-handling races (Bug#12471).
3671 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3672 Avoid recursive loop if there's a fatal error in the function itself.
3673 * atimer.c (pending_atimers):
3674 * blockinput.h: Don't include "atimer.h"; no longer needed.
3675 (interrupt_input_pending): Remove. All uses removed.
3676 pending_signals now counts both atimers and ordinary interrupts.
3677 This is less racy than having three separate pending-signal flags.
3678 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3680 Rename from their upper-case counterparts BLOCK_INPUT,
3681 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3682 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3683 This makes it easier to access volatile variables more accurately.
3684 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3685 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3686 that's more reliable if the code is buggy and sets
3687 interrupt_input_blocked to a negative value. All uses changed.
3688 * atimer.c (deliver_alarm_signal):
3689 Remove. No need to deliver this to the parent; any thread can
3690 handle this signal now. All uses replaced by underlying handler.
3691 * atimer.c (turn_on_atimers):
3692 * dispnew.c (handle_window_change_signal):
3693 * emacs.c (handle_danger_signal):
3694 * keyboard.c (kbd_buffer_get_event):
3695 Don't reestablish signal handler; not needed with sigaction.
3696 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3698 Rework to avoid unnecessary accesses to volatile variables.
3699 (UNBLOCK_INPUT_TO): Now a function.
3700 (totally_unblock_input, unblock_input): New decls.
3701 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3702 (init_data): Remove. Necessary stuff now done in init_signal.
3703 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3704 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3705 (fatal_error_code): Remove; no longer needed.
3706 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3707 it doesn't always backtrace. All uses changed. No need to reset
3708 signal to default, since sigaction and/or die does that for us now.
3709 Use emacs_raise (FOO), not kill (getpid (), FOO).
3710 (main): Check more-accurately whether we're dumping.
3711 Move fatal-error setup to sysdep.c
3712 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3713 * gtkutil.c (xg_get_file_name, xg_get_font):
3714 Remove no-longer-needed signal-mask manipulation.
3715 * keyboard.c, process.c (POLL_FOR_INPUT):
3716 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3717 * keyboard.c (read_avail_input): Remove.
3718 All uses replaced by gobble_input.
3719 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3720 (kbd_buffer_store_event_hold, gobble_input):
3721 (record_asynch_buffer_change) [USABLE_SIGIO]:
3722 (store_user_signal_events):
3723 No need to mess with signal mask.
3724 (gobble_input): If blocking input and there are terminals, simply
3725 set pending_signals to 1 and return. All hooks changed to not
3726 worry about whether input is blocked.
3727 (process_pending_signals): Clear pending_signals before processing
3728 them, in case a signal comes in while we're processing.
3729 By convention callers now test pending_signals before calling us.
3730 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3731 New functions, to support changes to blockinput.h.
3732 (handle_input_available_signal): Now extern.
3733 (reinvoke_input_signal): Remove. All uses replaced by
3735 (quit_count): Now volatile, since a signal handler uses it.
3736 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3737 All callers changed. Block SIGINT only if not already blocked.
3738 Clear sigmask reliably, even if Fsignal returns, which it can.
3739 Omit unnecessary accesses to volatile var.
3740 (quit_throw_to_read_char): No need to restore sigmask.
3741 * keyboard.c (gobble_input, handle_user_signal):
3742 * process.c (wait_reading_process_output):
3743 Call signal-handling code rather than killing ourselves.
3744 * lisp.h: Include <float.h>, for...
3745 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3746 (pending_signals): Now volatile.
3747 (syms_of_data): Now const if IEEE floating point.
3748 (handle_input_available_signal) [USABLE_SIGIO]:
3749 (terminate_due_to_signal, record_child_status_change): New decls.
3750 * process.c (create_process): Avoid disaster if memory is exhausted
3751 while we're processing a vfork, by tightening the critical section
3753 (send_process_frame, process_sent_to, handle_pipe_signal)
3754 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3756 (send_process): No need for setjmp/longjmp any more, since the
3757 SIGPIPE stuff is now gone. Instead, report an error if errno
3759 (record_child_status_change): Now extern. PID and W are now args.
3760 Return void, not bool. All callers changed.
3761 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3762 Remove. All uses removed. This bug should be fixed now in a
3764 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3765 and record the child status change directly. This avoids the
3766 need to futz with the signal mask.
3767 (process_fatal_action): Move here from emacs.c.
3768 (emacs_sigaction_flags): New function, containing
3769 much of what used to be in emacs_sigaction_init.
3770 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3771 caught by emacs, to make races less likely.
3772 (deliver_process_signal): Rename from handle_on_main_thread.
3774 (BACKTRACE_LIMIT_MAX): Now at top level.
3775 (thread_backtrace_buffer, threadback_backtrace_pointers):
3777 (deliver_thread_signal, deliver_fatal_thread_signal):
3778 New functions, for more-accurate delivery of thread-specific signals.
3779 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3780 (deliver_arith_signal): Handle in this thread, not
3781 in the main thread, since it's triggered by this thread.
3782 (maybe_fatal_sig): New function.
3783 (init_signals): New arg DUMPING so that we can be more accurate
3784 about whether we're dumping. Caller changed.
3785 Treat thread-specific signals differently from process-general signals.
3786 Block all signals while handling fatal error; that's safer.
3787 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3789 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3790 Ignore SIGPIPE unless batch.
3791 (emacs_backtrace): Output backtrace for the appropriate thread,
3792 which is not necessarily the main thread.
3793 * syssignal.h: Include <stdbool.h>.
3794 (emacs_raise): New macro.
3795 * xterm.c (x_connection_signal): Remove; no longer needed
3796 now that we use sigaction.
3797 (x_connection_closed): No need to mess with sigmask now.
3798 (x_initialize): No need to reset SIGPIPE handler here, since
3799 init_signals does this for us now.
3801 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3803 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3804 background rect may be larger (Bug#12245).
3806 2012-09-23 Chong Yidong <cyd@gnu.org>
3808 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3810 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3812 * .gdbinit: Just stop at fatal_error_backtrace.
3813 See Stefan Monnier's request in
3814 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3815 Remove no-longer-used query of system type.
3817 2012-09-22 Chong Yidong <cyd@gnu.org>
3819 * search.c (Freplace_match): Doc fix (Bug#12325).
3821 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3823 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3824 (Fline_end_position): Doc fix.
3826 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3828 2012-09-22 Chong Yidong <cyd@gnu.org>
3830 * dispextern.h (struct image_type): Add new slot, storing a type
3831 initialization function.
3833 * image.c (define_image_type): Call the image initializer function
3834 if it is defined. Arguments and return value changed.
3835 (valid_image_p, make_image): Callers changed.
3836 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3837 (gif_type, imagemagick_type, svg_type, gs_type):
3838 Add initialization functions.
3839 (Finit_image_library): Call lookup_image_type.
3840 (CHECK_LIB_AVAILABLE): Macro deleted.
3841 (lookup_image_type): Call define_image_type here, rather than via
3842 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3843 (syms_of_image): Move define_image_type calls for xbm_type and
3844 pbm_type to lookup_image_type.
3846 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3848 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3849 'idle_timers' from here ...
3850 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3851 lists, to avoid infloops when the timer does something stupid,
3852 like reinvoke itself with the same or smaller time-out.
3855 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3857 * window.c (Fsplit_window_internal): Handle only Qt value of
3858 Vwindow_combination_limit separately.
3859 (Qtemp_buffer_resize): New symbol.
3860 (Vwindow_combination_limit): New default value.
3863 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3865 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3866 the new overlay string. (Bug#10159)
3868 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3870 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3871 or that fprintf is async-signal-safe. POSIX doesn't require
3874 2012-09-22 Chong Yidong <cyd@gnu.org>
3876 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3879 2012-09-22 Kenichi Handa <handa@gnu.org>
3881 * composite.c (composition_reseat_it): Handle the case that a
3882 grapheme cluster is not covered by a single font (Bug#12352).
3884 2012-09-21 Chong Yidong <cyd@gnu.org>
3886 * image.c (define_image_type): Avoid adding duplicate types to
3887 image_types (Bug#12463). Suggested by Jörg Walter.
3889 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3891 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3892 (print_load_command_name): Add case LC_DATA_IN_CODE.
3893 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3895 2012-09-21 Glenn Morris <rgm@gnu.org>
3897 * eval.c (Frun_hook_with_args_until_success)
3898 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3900 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3902 * fileio.c (Ffile_selinux_context): Only call freecon when
3903 lgetfilecon succeeded.
3904 (Fset_file_selinux_context): Likewise. (Bug#12444)
3906 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3908 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3909 reordering, locate the cursor by calling set_cursor_from_row; if
3910 that fails, clear the desired glyph matrix before returning a
3911 failure indication to the caller. Fixes leaving garbled display
3912 when fast scrolling with a down-key. (Bug#12403)
3913 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3914 scrolling through multibyte text.
3916 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3918 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3919 calling mark_vectorlike since that's the one that marks the window.
3920 (mark_discard_killed_buffers): Mark the final cdr.
3921 * window.h (struct window): Move prev/next_buffers to the
3922 non-standard fields.
3923 * window.c (make_window): Initialize prev/next_buffers manually.
3925 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3927 Omit unused arg EXPECTED from socket hooks.
3928 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3929 * nsterm.m (ns_term_init):
3930 * termhooks.h (struct terminal.read_socket_hook):
3931 * w32inevt.c (w32_console_read_socket):
3932 * w32term.c (w32_read_socket):
3933 * xterm.c (XTread_socket):
3934 Omit unused arg EXPECTED. All callers changed.
3935 (store_user_signal_events): Return void, not int, since callers no
3936 longer care about the return value. All uses changed.
3938 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3940 * w32gui.h (XParseGeometry): Do not declare.
3942 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3944 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3945 Ignore 'expected'. See Eli Zaretskii in
3946 <http://bugs.gnu.org/12471#8> (last line).
3948 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3949 (XParseGeometry): Now static. Substitute extremal values for
3950 values that are out of range.
3952 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3954 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3956 * nsfns.m (XParseGeometry): Remove.
3957 (Fx_create_frame): Call x_set_offset to correctly interpret
3958 top_pos in geometry.
3960 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3961 (Fx_parse_geometry): If there is a space in string, call
3962 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3964 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3966 * search.c (scan_buffer): Use character positions in calls to
3967 region_cache_forward and region_cache_backward, not byte
3968 positions. (Bug#12196)
3970 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3971 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3973 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3974 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3975 emacs_blocked_malloc, now deleted.
3977 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3979 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3980 The workaround was for improving performance on Solaris 2.4, but
3981 is getting in the way now. Emacs will still work if someone is
3982 still running Solaris 2.4 in a museum somewhere; Sun dropped
3983 support for Solaris 2.4 in 2003.
3984 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3985 * process.c (create_process) [HAVE_WORKING_VFORK]:
3986 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3987 since Emacs no longer uses vfork on that platform.
3989 2012-09-17 Glenn Morris <rgm@gnu.org>
3991 * emacs.c: Use COPYRIGHT.
3993 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3995 Remove configure's --without-sync-input option (Bug#12450).
3996 When auditing signal-handling in preparation for cleaning it up,
3997 I found that SYNC_INPUT has race conditions and would be a real
3998 pain to fix. Since it's an undocumented and deprecated
3999 configure-time option, now seems like a good time to remove it.
4000 Also see <http://bugs.gnu.org/11080#16>.
4001 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4002 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4003 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4004 (malloc_hysteresis):
4005 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4006 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4007 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4008 (dont_register_blocks, bytes_used_when_reconsidered)
4009 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4010 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4011 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4012 Remove. All uses removed.
4013 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4014 implementation, one that depends on whether the new macro
4015 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4017 * atimer.c (run_timers, handle_alarm_signal):
4018 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4019 (handle_async_input, process_pending_signals)
4020 (handle_input_available_signal, init_keyboard):
4021 * nsterm.m (ns_read_socket):
4022 * process.c (wait_reading_process_output):
4023 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4024 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4026 * xterm.c (XTread_socket):
4028 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4029 * eval.c (handling_signal): Remove. All uses removed.
4030 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4031 All uses replaced with the SYNC_INPUT version.
4032 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4034 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4037 * font.c (Ffont_shape_gstring): Remove unused local.
4039 2012-09-16 Glenn Morris <rgm@gnu.org>
4041 * Makefile.in (clean): No longer run nextstep's clean.
4043 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4045 (ns-app): Move here from ns.mk, and simplify.
4046 (clean): Simplify nextstep entry.
4047 * ns.mk: Remove file.
4049 2012-09-17 Kenichi Handa <handa@gnu.org>
4051 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4052 not covert the last few charactes.
4054 2012-09-16 Kenichi Handa <handa@gnu.org>
4056 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4057 here, but just check the validity of glyphs in the glyph-string.
4059 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4061 * window.c (Fwindow_parameter, Fset_window_parameter):
4062 Accept any window as argument (Bug#12452).
4064 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4066 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4067 to ns_term_init to avoid memory leak.
4069 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4070 explicit retain/release.
4071 (ns_term_init): Only allow one display. Initialize outerpool and
4074 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4076 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4077 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4078 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4079 the Microsoft problem in a different way, by altering ../nt/config.nt.
4081 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4096 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4097 by lisp.h. This completes removal of setjmp.h inclusion
4098 erroneously announced in the previous commit. (Bug#12446)
4100 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4103 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4104 not defined as a macro. The latter happens on MS-Windows.
4107 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4109 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4110 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4111 Some instances of '#include <setjmp.h>' removed, if the
4112 only reason for the instance was because "lisp.h" was included.
4113 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4114 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4115 and _longjmp with the new symbols. Emacs already uses _setjmp if
4116 available, so this change affects only POSIXish hosts that have
4117 sigsetjmp but not _setjmp, such as some versions of Solaris and
4118 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4119 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4120 (png_load_body) [HAVE_PNG]:
4121 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4122 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4123 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4124 since PNG requires jmp_buf. This is the only exception to the
4125 general rule that we now use sys_setjmp and sys_longjmp.
4126 This exception is OK since this code does not change the signal
4127 mask or longjmp out of a signal handler.
4129 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4131 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4132 Include "syssignal.h", for 'main_thread'.
4134 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4136 Avoid out-of-range marker position (Bug#12426).
4137 * insdel.c (replace_range, replace_range_2):
4138 Adjust markers before overlays, as suggested by comments.
4139 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4140 Remove redundant check before calling offset_intervals.
4142 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4144 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4145 current buffer (Bug#12387).
4147 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4149 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4151 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4153 Use a more backwards-compatible timer format (Bug#12430).
4154 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4155 vector element, not from the 4th, since PSECS is now at the end.
4156 (Fcurrent_idle_time): Doc fix.
4158 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4160 Function to mark objects and remove killed buffers at once.
4161 * alloc.c (discard_killed_buffers): Rename to ...
4162 (mark_discard_killed buffers) ... new name. Add marking
4163 of remaining objects. Fix comment. Adjust users.
4164 (mark_object): Do not touch frame buffer lists here.
4165 * frame.c (delete_frame): Reset frame buffer lists here.
4167 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4169 Better workaround for GNOME bug when --enable-gcc-warnings.
4170 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4171 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in

4174 Simplify SIGIO usage (Bug#12408).
4175 The code that dealt with SIGIO was crufty and confusing, e.g., it
4176 played tricks like "#undef SIGIO" but these tricks were not used
4177 consistently. Simplify mostly by not #undeffing standard symbols,
4178 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4179 or not as we please) rather than "defined SIGIO" (standard symbol
4180 that we probably shouldn't #undef).
4181 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4182 Modules that need it can include it.
4183 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4184 * dispextern.h (ignore_sigio): New decl.
4185 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4186 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4187 * emacs.c (shut_down_emacs):
4188 * keyboard.c (kbd_buffer_store_event_hold):
4189 Use ignore_sigio rather than invoking 'signal' directly.
4190 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4192 (FIONREAD, SIGIO): Do not #undef.
4193 (tty_read_avail_input): Use #error rather than a syntax error.
4194 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4195 for I_PIPE, used by SETUP_SLAVE_PTY.
4196 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4197 * sysdep.c (croak): Remove; no longer needed. This bit of
4198 temporary code, with Fred N. Fish's comment that it's temporary,
4199 has been in Emacs since at least 1992!
4200 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4201 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4202 * syssignal.h (croak): Remove decl.
4203 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4204 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4205 now that we're termios-only.
4206 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4207 * term.c (dissociate_if_controlling_tty): Use #error rather than
4210 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4211 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4212 to work around GNOME bug 683906.
4213 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4214 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4215 This works around GCC bug 54561.
4217 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4219 More fixes for 'volatile' and setjmp/longjmp.
4220 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4221 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4222 (png_load_body) [HAVE_PNG]:
4223 (jpeg_load_body) [HAVE_JPEG]:
4224 New function, with most of the old parent function's body.
4225 (png_load) [HAVE_PNG]:
4226 (jpeg_load) [HAVE_JPEG]:
4227 Invoke the new function, to avoid longjmp munging our locals.
4228 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4229 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4230 longjmp is passed 2, as the C standard doesn't guarantee this.
4231 Instead, store the failure code into mgr->failure_code.
4233 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4235 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4236 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4237 (syms_of_keyboard): Remove support for unread-command-char.
4239 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4241 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4242 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4243 violation. (Bug#12426)
4245 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4247 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4249 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4251 * eval.c: Add `inhibit-debugger'.
4252 (Qinhibit_debugger): New symbol.
4253 (call_debugger): Bind it instead of Qdebug_on_error.
4254 (maybe_call_debugger): Test Vinhibit_debugger.
4255 (syms_of_eval): Define inhibit-debugger.
4256 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4257 (syms_of_xdisp): Remove inhibit-debug-on-message.
4259 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4261 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4262 If a nonvolatile local variable is written before a _longjmp to
4263 the frame containing the variable, and is read after the _longjmp,
4264 the value read is indeterminate. Some local variables of type
4265 'struct handler' and 'struct catchtag' are used in this way, so
4266 mark each of their slots as volatile if the slot can be set before
4267 _longjmp and read afterwards.
4268 * lisp.h (struct handler): var and chosen_clause are now volatile.
4269 (struct catchtag): val, next, and pdlcount are now volatile.
4271 * bidi.c (bidi_push_it, bidi_pop_it):
4272 * fns.c (copy_hash_table):
4273 * image.c (define_image_type):
4274 * keyboard.c (kbd_buffer_store_event_hold):
4275 * process.c (Fprocess_send_eof):
4276 * xfaces.c (x_create_gc) [HAVE_NS]:
4277 * xgselect.c (xg_select):
4278 Prefer assignment to memcpy when either will do.
4280 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4281 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4282 time an item is removed. No need to mark this function 'inline';
4283 the compiler knows better than we do.
4285 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4287 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4288 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4289 to change_frame_size (Bug#12388).
4290 (windowDidResize:): Pass YES to updateFrameSize.
4292 * nsterm.h: Add delay parameter to updateFrameSize.
4294 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4296 Discard killed buffers from deleted window and frame objects.
4297 This reduces an amount of references to killed buffers and
4298 helps GC to reclaim them faster.
4299 * alloc.c (discard_killed_buffers): New function.
4300 (mark_object): Use it for deleted windows and frames.
4301 (mark_object): If symbol's value is set up for a killed buffer
4302 or deleted frame, restore its global binding.
4303 * data.c (swap_in_global_binding): Add GC notice.
4304 (swap_in_symval_forwarding): Use convenient set_blv_where.
4305 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4306 * window.h: ... to here.
4308 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4310 Convenient macro to check whether the buffer is live.
4311 * buffer.h (BUFFER_LIVE_P): New macro.
4312 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4313 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4315 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4317 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4318 composition cases (Bug#12364).
4320 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4321 overhang of succeeding glyphs overlapping box cursor.
4323 * w32term.c (x_draw_glyph_string): Likewise.
4325 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4327 Simplify, document, and port floating-point (Bug#12381).
4328 The porting part of this patch fixes bugs on non-IEEE platforms
4329 with frexp, ldexp, logb.
4330 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4332 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4333 support, by removing commented-out code and briefly listing the
4334 C89 functions excluded. The commented-out stuff was confusing
4335 maintenance, e.g., we thought we needed cbrt but it was commented out.
4336 (logb): Remove decl; no longer needed.
4337 (isfinite): New macro, if not already supplied.
4338 (isnan): Don't replace any existing macro.
4339 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4340 are present on all C89 platforms.
4341 (Ffrexp): Do not special-case zero, as frexp does the right thing
4343 (Flogb): Do not use logb, as it doesn't have the desired meaning
4344 on hosts that use non-base-2 floating point. Instead, stick with
4345 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4346 frexp, to avoid getting an unspecified result.
4348 * xdisp.c (Qinhibit_debug_on_message): Now static.
4350 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4352 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4353 NSBezierPath (Bug#12131).
4355 2012-09-10 Chong Yidong <cyd@gnu.org>
4357 * fns.c (Fdelq, Fdelete): Doc fix.
4359 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4361 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4362 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4364 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4366 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4367 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4370 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4372 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4373 left fringe if the window has a left margin. This avoids leaving
4374 traces of the cursor because its leftmost pixel is not drawn over.
4376 * dispnew.c (update_window_line): When the left margin area of a
4377 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4378 that screen line. (Bug#12277)
4380 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4382 Assume C89 or later for math functions (Bug#12381).
4383 This simplifies the code, and makes it a bit smaller and faster,
4384 and (most important) makes it easier to clean up signal handling
4385 since we can stop worring about floating-point exceptions in
4386 library code. That was a problem before C89, but the problem
4387 went away many years ago on all practical Emacs targets.
4388 * data.c, image.c, lread.c, print.c:
4389 Don't include <math.h>; no longer needed.
4390 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4391 might be autoconfigured, as that never happens.
4393 * doprnt.c (DBL_MAX_10_EXP):
4394 * print.c (DBL_DIG):
4395 Remove. C89 or later always defines these.
4396 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4397 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4398 (arith_error, domain_error, domain_error2):
4399 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4400 no longer needed -- we simply return what C returns. All uses removed.
4401 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4403 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4404 Remove. All uses expanded, as these macros are no longer used
4405 more than once and are now more trouble than they're worth.
4406 (Ftan): Use tan, not sin / cos.
4407 (Flogb): Assume C89 frexp.
4408 (fmod_float): Assume C89 fmod.
4409 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4410 (init_floatfns): Remove. All uses removed.
4412 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4414 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4415 compositeToPoint for OSX < 10.6 (Bug#12390).
4417 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4419 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4420 This produces more-accurate results.
4422 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4424 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4425 changes (Bug#12088).
4427 2012-09-08 Chong Yidong <cyd@gnu.org>
4429 * syntax.c (Fstring_to_syntax): Doc fix.
4431 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4433 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4434 in the internal border.
4435 (x_set_window_size): Remove static variables and their usage.
4436 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4437 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4438 Remove fringe/internal border adjustment (Bug#11052).
4439 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4440 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4441 (ns_fix_rect_ibw): Remove.
4442 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4443 (ns_dumpglyphs_box_or_relief): Ditto.
4444 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4446 (ns_dumpglyphs_image): Ditto.
4447 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4449 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4450 their usage. Add fringe_extended_p and its use as in other terms.
4451 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4452 scroll bar was removed.
4453 (updateFrameSize): New function.
4454 (windowDidResize): Move code to updateFrameSize and call it.
4456 * nsterm.h (EmacsView): Add updateFrameSize.
4458 2012-09-07 Chong Yidong <cyd@gnu.org>
4460 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4462 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4464 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4466 More signal-handler cleanup (Bug#12327).
4467 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4468 Problem introduced when merging patches. Noted by Eli Zaretskii in
4469 <http://bugs.gnu.org/12327#67>.
4470 * floatfns.c: Comment fix.
4471 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4472 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4473 and anyway the declaration is harmless even if SIGDANGER is not defined.
4474 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4475 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4476 source files not surprisingly expected syssignal.h to define, or
4477 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4478 Include <sys/ioctl.h>, for FIONREAD.
4479 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4480 This eliminates a problem whereby other files mysteriously had
4481 to include "syssignal.h" before including "systty.h" if they
4482 wanted to use "#ifdef SIGIO".
4484 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4486 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4488 * w32.c (sigemptyset): Empty the set.
4489 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4491 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4493 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4495 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4496 (mark_object): Likewise for frame objects.
4498 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4500 * syssignal.h (handle_on_main_thread): Always declare,
4501 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4502 This ports to platforms without HAVE_PTHREAD.
4504 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4506 Signal-handler cleanup (Bug#12327).
4507 Emacs's signal handlers were written in the old 4.2BSD style with
4508 sigblock and sigmask and so forth, and this led to some
4509 inefficiencies and confusion. Rewrite these to use
4510 pthread_sigmask etc. without copying signal sets around. Also,
4511 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4512 'signal', and instead use functions that do not attempt to take
4513 over the system name space. This patch causes Emacs's text
4514 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4515 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4516 Do not include <signal.h> or "syssignal.h", as these
4517 modules do not use signals.
4518 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4519 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4520 Do not include <signal.h>, as "syssignal.h" does that for us now.
4521 * atimer.c (sigmask_atimers): New function.
4522 (block_atimers, unblock_atimers): New functions,
4523 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4525 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4526 no longer needed here.
4527 * emacs.c (main): Inspect existing signal handler with sigaction,
4528 so that there's no need to block and unblock SIGHUP.
4529 * sysdep.c (struct save_signal): New member 'action', replacing
4530 old member 'handler'.
4531 (save_signal_handlers, restore_signal_handlers):
4532 Use sigaction instead of 'signal' to save and restore.
4533 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4534 New function. All users of 'signal' modified to use set_sighandler
4535 if they're writeonly, and to use sys_signal if they're read+write.
4536 (emacs_sigaction_init, forwarded_signal): New functions.
4537 (sys_signal): Remove. All uses replaced by calls to sigaction
4538 and emacs_sigaction_init, or by direct calls to 'signal'.
4539 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4540 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4541 all uses replaced by pthread_sigmask etc. calls.
4542 * syssignal.h: Include <signal.h>.
4543 (emacs_sigaction_init, forwarded_signal): New decls.
4544 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4545 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4546 (sigmask, sys_sigmask): Remove; no longer needed.
4547 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4548 (sigblock, sigunblock, sigfree):
4549 (sigsetmask) [!defined sigsetmask]:
4550 Remove. All uses replaced by pthread_sigmask.
4551 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4552 no longer need to be replaced, and its typical old uses
4553 are now done via emacs_sigaction_init and sigaction.
4554 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4555 (sys_sigdel): Remove; unused.
4556 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4558 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4560 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4561 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4563 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4565 Explicitly mark buffer_defaults and buffer_local_symbols.
4566 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4567 mark_local_symbols here.
4568 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4569 since special buffers aren't marked here any more.
4570 (allocate_buffer): Chain new buffer with all_buffers here...
4571 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4573 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4574 (syms_of_buffer): Remove staticpro of the above.
4575 (init_buffer_once): Set names for buffer_defaults and
4576 buffer_local_symbols.
4578 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4580 Use bool for booleans in font-related modules.
4581 * font.c (font_intern_prop, font_style_to_value)
4582 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4583 (generate_otf_features, font_check_otf_features, font_check_otf)
4584 (font_match_p, font_list_entities, font_at):

4586 (fontset_find_font, Fset_fontset_font)
4587 (face_suitable_for_char_p) [0]:
4588 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4589 (ftfont_open, ftfont_text_extents, ftfont_check_otf):

4592 * nsfont.m (nsfont_draw):
4593 * w32font.c (w32font_draw):
4594 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4595 Use bool for booleans.
4596 * font.h: Adjust to above API changes.
4597 (struct font, struct font_driver, struct font_driver_list):
4598 Use bool for booleans.
4599 (struct font): Remove useless member encoding_type.
4601 * fontset.c, xftfont.c: Omit unnecessary static decls.
4603 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4605 * alloc.c (mark_object): Revert window marking code
4606 since it's unsafe for the Fset_window_configuration.
4608 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4610 Fix race conditions with signal handlers and errno (Bug#12327).
4611 Be more systematic about preserving errno whenever a signal
4612 handler returns, even if it's not in the main thread. Do this by
4613 renaming signal handlers to distinguish between signal delivery
4614 and signal handling. All uses changed.
4615 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4616 * data.c (deliver_arith_signal): Rename from arith_error.
4617 * dispnew.c (deliver_window_change_signal): Rename from
4618 window_change_signal.
4619 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4620 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4621 * keyboard.c (deliver_input_available_signal): Rename from
4622 input_available_signal.
4623 (deliver_user_signal): Rename from handle_user_signal.
4624 (deliver_interrupt_signal): Rename from interrupt_signal.
4625 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4626 (deliver_child_signal): Rename from sigchld_handler.
4627 * atimer.c (handle_alarm_signal):
4628 * data.c (handle_arith_signal):
4629 * dispnew.c (handle_window_change_signal):
4630 * emacs.c (handle_fatal_signal, handle_danger_signal):
4631 * keyboard.c (handle_input_available_signal):
4632 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4633 * process.c (handle_pipe_signal, handle_child_signal):
4634 New functions, with the actual signal-handling code taken from the
4635 original respective signal handlers, sans the sporadic attempts to
4636 preserve errno, since that's now done by handle_on_main_thread.
4637 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4638 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4639 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4641 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4642 Move initialization of main_thread to sysdep.c's init_signals.
4643 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4644 our usage, and simplifies the mainline code.
4645 (record_child_status_change): New static function, as a helper
4646 for handle_child_signal, and with most of the old child handler's
4648 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4649 (handle_child_signal): Use the above.
4650 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4651 Moved here from emacs.c.
4652 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4653 code moved here from emacs.c's main function.
4654 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4655 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4656 This lets callers save and restore errno properly.
4658 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4660 Remove redundant or unused things here and there.
4661 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4662 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4663 * editfns.c (Fcompare_buffer_substrings): Likewise.
4664 * frame.h (struct terminal, struct font_driver_list):
4665 Remove redundant declarations.
4666 * window.h (Qleft, Qright): Likewise.
4668 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4670 Do not mark objects from deleted buffers, windows and frames.
4671 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4672 (mark_object): Likewise for windows and frames.
4674 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4676 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4677 buffer_defaults and buffer_local_symbols as valid objects.
4678 Return special value to denote them.
4680 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4682 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4683 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4684 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4685 (file_name_absolute_p, Fsubstitute_in_file_name):
4686 (check_executable, check_writable, Ffile_accessible_directory_p)
4687 (Fset_file_selinux_context, Fdefault_file_modes)
4688 (Finsert_file_contents, choose_write_coding_system)
4689 (Fwrite_region, build_annotations, a_write, e_write)
4691 * filelock.c (boot_time_initialized, get_boot_time)
4692 (get_boot_time_1, lock_file_1, within_one_second):
4693 * floatfns.c (in_float):
4694 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4695 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4696 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4697 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4698 * window.c (compare_window_configurations):
4699 Use bool for booleans.
4700 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4701 (Fdefault_file_modes): Now mode_t, not int, for modes.
4702 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4703 (internal_delete_file): Now returns void, not a (boolean) int,
4704 since nobody was looking at the return value.
4705 * lisp.h, window.h: Adjust to above API changes.
4707 * xdisp.c (set_message): Simplify and reindent last change.
4709 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4711 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4713 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4715 * eval.c (call_debugger): Make the function non-static so that we
4716 can call it from set_message.
4718 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4719 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4721 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4723 Give more-useful info on a fatal error (Bug#12328).
4724 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4725 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4726 of doing the work ourselves.
4727 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4728 do most of the work.
4729 (fatal_error_backtrace): New function, taken from the guts
4730 of the old fatal_error_signal, but with a new option to output
4732 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4733 info about the signal than just its number.
4734 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4735 * sysdep.c: Include <execinfo.h>
4736 (emacs_backtrace): New function, taken partly from the previous
4737 code of the 'die' function.
4738 (emacs_abort): Call fatal_error_backtrace rather than abort.
4740 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4742 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4743 eager (load-time) macro-expansion.
4744 * lisp.mk (lisp): Add macroexp.
4746 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4748 Simplify redefinition of 'abort' (Bug#12316).
4749 Do not try to redefine the 'abort' function. Instead, redo
4750 the code so that it calls 'emacs_abort' rather than 'abort'.
4751 This removes the need for the NO_ABORT configure-time macro
4752 and makes it easier to change the abort code to do a backtrace.
4753 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4754 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4755 Remove; sysdep.c's emacs_abort now takes its place.
4756 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4757 'abort' changed to use 'emacs_abort'.
4758 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4759 (abort) [!defined abort]: Rename to ...
4760 (emacs_abort): ... new name.
4761 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4762 the place of the old 'abort' in emacs.c.
4763 * w32.c, w32fns.c (abort): Do not #undef.
4764 * w32.c (emacs_abort): Rename from w32_abort.
4766 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4768 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4769 offsets[j].dv, since the y axis of the screen coordinates points
4770 down, while the y axis of the font definition coordinates points
4771 up. This fixes display of Arabic diacritics such as KASRA and
4772 KASRATAN. (Bug#11860)
4774 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4776 Be more systematic about _setjmp vs setjmp.
4777 * alloc.c (test_setjmp, mark_stack):
4778 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4779 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4780 (png_load, my_error_exit, jpeg_load):
4781 * process.c (send_process_trap, send_process):
4782 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4783 The underscored versions are up to 30x faster on some hosts.
4784 Formerly, the code used setjmp+longjmp sometimes and
4785 _setjmp+_longjmp at other times, with no particular reason to
4786 prefer setjmp+longjmp.
4788 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4790 Fix minor problem found by static checking.
4791 * buffer.c (Fdelete_all_overlays): Return nil.
4793 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4795 * buffer.c (Fdelete_all_overlays): New function.
4797 2012-09-03 Chong Yidong <cyd@gnu.org>
4799 * gtkutil.c: Add extern decl for Qxft.
4801 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4803 * emacs.c, eval.c: Use bool for boolean.
4804 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4805 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4806 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4807 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4808 (main, decode_env_path, Fdaemon_initialized):
4809 * eval.c (call_debugger, Finteractive_p, interactive_p):
4810 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4811 (maybe_call_debugger, Fbacktrace):
4812 * process.c (read_process_output, exec_sentinel):
4813 Use bool for booleans.
4814 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4815 All callers changed.
4816 * eval.c (interactive_p): Omit always-true boolean argument
4817 EXCLUDE_SUBRS_P. All callers changed.
4818 * dispextern.h, lisp.h: Reflect above API changes.
4819 * firstfile.c (dummy): Use the address of 'main', whose signature
4820 won't change, instead of the address of 'initialize', whose
4821 signature just changed from int to bool.
4822 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4823 * msdos.c (fatal_error_in_progress): ... from here.
4824 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4826 (redisplay_internal, unwind_redisplay): Simply clear
4827 REDISPLAYING_P when unwinding, instead of saving its previous,
4828 always-false value and then restoring it.
4830 Clean up some extern decls.
4831 Mostly, this hoists extern decls out of .c files and into .h files.
4832 That way, we're more likely to catch errors if the interfaces change.
4833 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4834 declare xg_mark_data.
4835 * dispextern.h (x_frame_parm_handlers):
4837 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4838 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4839 (Qultra_bold, Qoblique, Qitalic):
4840 Move extern decl here from .c file.
4841 * alloc.c (xg_mark_data) [USE_GTK]:
4843 * eval.c (Qlexical_binding):
4844 * fns.c (time) [!HAVE_UNISTD_H]:

4850 * process.c (QCfamily, QCfilter):
4851 * widget.c (free_frame_faces):
4852 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4853 * xfont.c (x_clear_errors):
4854 * xterm.c (x_frame_parm_handlers):
4855 Remove now-redundant extern decls.
4856 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4857 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4859 * xfaces.c: Remove unnecessary static decls.
4860 * xterm.c (updating_frame): Remove decl of nonexistent object.
4862 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4863 when building globals.h, as the objects that are not built on
4864 this host are not needed to compile C files on this host.
4866 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4868 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4870 * frame.h: Add missing prototype for x_wm_set_size_hint.
4872 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4876 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4877 (Fsubstitute_command_keys):

4882 (make_buffer_string, make_buffer_string_both)
4883 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

4906 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4908 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4909 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

4914 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4916 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4918 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4919 more than one grapheme cluster passed to the shaper: compute the
4920 offset adjustment values separately for each cluster. (Bug#11860)
4922 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4923 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4924 about implicit conversions from integer to pointer.
4926 2012-09-01 Daniel Colascione <dancol@dancol.org>
4928 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4929 system used too early.
4931 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
4933 Better seed support for (random).
4934 * emacs.c (main): Call init_random.
4935 * fns.c (Frandom): Set the seed from a string argument, if given.
4936 Remove long-obsolete Gentzel cruft.

4946 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
4947 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
4948 all of which have been moved to common code.
4950 * xfaces.c: Include TERM_HEADER instead of listing all possible
4951 window-system headers.
4953 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

4957 directly accessing frame internals.
4959 * w32font.h: Include font.h. Define syms_of_w32font and
4962 * process.c: Include TERM_HEADER instead of listing all possible
4963 window-system headers.
4965 * nsterm.h: Remove declarations now in frame.h.
4966 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
4968 * menu.c: Include TERM_HEADER instead of listing all possible
4969 window-system headers.
4971 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
4974 * keyboard.c: Include TERM_HEADER instead of listing all possible
4975 window-system headers.
4977 * image.c: Include TERM_HEADER instead of listing all possible
4978 window-system headers. Declare Vlibrary_cache when compiling for
4981 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
4982 window system declarations.
4984 * frame.h: Move common functions here: set_frame_menubar,
4985 x_set_window_size, x_sync, x_get_focus_frame,
4986 x_set_mouse_position, x_set_mouse_pixel_position,
4987 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5007 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
5008 the current window system; include in list of objects to link into
5011 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5013 Remove mark_ttys function and fix tty_display_info initialization.
5014 * lisp.h (mark_ttys): Remove prototype.
5015 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5016 to mark_ttys because all possible values of 'top_frame' slot are
5017 the frames which are reachable from Vframe_list.
5018 * term.c (mark_ttys): Remove.
5019 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5021 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5023 Change struct frame bitfields from unsigned char to unsigned.
5024 * frame.h (struct frame): Change type of 'display_preempted',
5025 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
5026 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
5027 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
5028 bitfields from unsigned char to unsigned.
5030 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5032 Remove unused member of struct x_output and struct w32_output.
5033 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
5034 * w32term.h (struct w32_output): Likewise.
5036 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
5038 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
5039 does not become zero (Bug#12234).
5041 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
5043 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
5044 for GCC 4.7.1 x86-64.
5046 2012-08-30 Glenn Morris <rgm@gnu.org>
5048 * lread.c (init_lread): For out-of-tree builds, only add the
5049 source directory's site-lisp dir to the load-path if it exists,
5050 consistent with in-tree builds. (Bug#12302)
5052 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5054 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
5055 button_values to NULL. Call setStykeMask so dialogs get a close button.
5056 (windowShouldClose:): Set window_closed.
5057 (dealloc): New member, free button_values.
5058 (process_dialog:): Make member function. Remove window argument,
5059 replace window with self. Count buttons and allocate and store values
5061 (addButton:value:row:): value is int with the name tag. Call setTag
5062 with tag. Remove return self, declare return value as void.
5063 (addString:row:): Remove return self, declare return value as void.
5064 (addSplit): Remove return self, declare return value as void.
5065 (clicked:): Remove return self, declare return value as void.
5066 Set dialog_return to button_values[seltag]. Code formatting change.
5067 (initFromContents:isQuestion:): Adjust call to process_dialog.
5068 Code formatting change.
5069 (timeout_handler:): Set timer_fired to YES.
5070 (runDialogAt:): Set timer_fired to NO.
5071 Handle click on close button as quit.
5073 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5074 Add window_closed and button_values. Add void as return value for
5075 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5076 Add process_dialog as new member.
5078 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5080 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
5081 is not one of the heaps we manage. (Bug#12242)
5083 2012-08-28 Glenn Morris <rgm@gnu.org>
5085 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
5087 2012-08-28 Martin Rudalics <rudalics@gmx.at>
5089 * window.c (Fset_window_configuration): Remove handling of
5090 auto-buffer-name window parameter. Install revision of reverted
5093 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
5095 Do not allow to set major mode for a dead buffer.
5096 * buffer.c (Fset_buffer_major_mode): Signal an error
5097 if the buffer is dead.
5098 (Fother_buffer, other_buffer_safely): Remove redundant
5101 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
5103 Always use set_buffer_if_live to restore original buffer at unwind.
5104 * buffer.h (record_unwind_current_buffer): New function.
5105 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
5106 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
5107 * undo.c, window.c: Adjust users.
5108 * buffer.c (set_buffer_if_live): Fix comment.
5110 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
5112 Fix usage of set_buffer_internal.
5113 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
5114 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
5115 * coding.c (decode_coding): Omit redundant test.
5116 * fileio.c (decide_coding_unwind): Likewise.
5117 * fns.c (secure_hash): Likewise.
5118 * insdel.c (modify_region): Likewise.
5119 * keyboard.c (command_loop_1): Likewise.
5120 * print.c (PRINTFINISH): Likewise.
5121 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
5123 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

5143 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
5144 and remove last int (actually boolean) argument, which was always 0.
5145 All callers changed.
5146 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
5147 * dispextern.h (struct composition_it): Use bool for boolean.
5148 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
5149 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
5150 * dired.c (file_name_completion):
5151 Use bool for boolean. (This was missed in an earlier change.)
5153 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5155 * window.c (Fset_window_configuration): Revert first part of
5158 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
5160 * nsterm.h (NSPanel): New class variable dialog_return.
5162 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
5163 Initialize dialog_return.
5164 (windowShouldClose:): Use stop instead of stopModalWithCode.
5165 (clicked:): Ditto, and also set dialog_return (Bug#12258).
5166 (timeout_handler:): Use stop instead of abortModal. Send a dummy
5168 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

5183 Use bool for booleans.
5184 * dired.c (file_name_completion):
5185 * process.h (fd_callback):
5186 Omit int (actually boolean) argument. It wasn't being used.
5188 * composite.h, lisp.h: Reflect above API changes.

5213 Use bool for booleans.
5214 * coding.h, lisp.h: Reflect above API changes.
5215 * coding.c: Remove unnecessary static function decls.
5216 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5217 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5218 not a boolean 'int', since callers never look at the return value.
5219 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5220 * coding.h (decoding_buffer_size, encoding_buffer_size)
5221 (emacs_mule_string_char): Remove unused extern decls.
5222 (struct iso_2022_spec, struct coding_system):
5223 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5224 (struct emacs_mule_spec): Remove unused field 'full_support'.
5225 All initializations removed.
5226 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5228 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5230 Fix spare memory change (Bug#12286).
5231 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5232 (valid_lisp_object_p): Likewise.
5234 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5236 * window.c (Fset_window_configuration): Record any window's old
5237 buffer if it's replaced (see Bug#8789). If the new current
5238 buffer doesn't appear in the selected window, go to its old
5241 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5243 Special MEM_TYPE_SPARE to denote reserved memory.
5244 * alloc.c (enum mem_type): New memory type.
5245 (refill_memory_reserve): Use new type for spare memory.
5246 This prevents live_cons_p and live_string_p from incorrect
5247 detection of uninitialized objects from spare memory as live.
5249 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5252 * Makefile.in (.PHONY): versioclean -> versionclean.
5254 Remove unused external symbols.
5255 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5256 * window.c (Qwindow_valid_p, decode_valid_window):
5257 Now static, not extern.
5258 * data.c (Qinterval): Remove; unused.
5259 (syms_of_data): Do not define 'interval'.
5260 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5261 * window.h (decode_valid_window):
5264 * character.c, charset.c, chartab.c: Use bool for booleans.

5275 (map_sub_char_table):
5276 Use bool for boolean.
5277 * character.c (str_to_unibyte): Omit last boolean argument; it was
5278 always 0. All callers changed.
5279 * character.h, charset.h: Adjust to match previous changes.
5280 * character.h (char_printable_p): Remove decl of nonexistent function.
5281 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5282 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5283 are all boolean, so make them single-bit bitfields.
5285 * lisp.h (ASET): Remove attempt to detect side effects.
5286 It was meant to be temporary and it often doesn't work,
5287 because when IDX has side effects the behavior of IDX==IDX
5288 is undefined. See Stefan Monnier in
5289 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5291 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5293 * lisp.h (functionp): New function (extracted from Ffunctionp).
5294 (FUNCTIONP): Use it.
5295 * eval.c (Ffunctionp): Use it.
5297 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5299 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5300 as that's faster and simpler than static storage. Don't bother
5301 with the g_main_context_query overhead if g_main_context_pending
5302 says no events are pending.
5303 (gfds, gfds_size): Remove these static vars.
5304 (xgselect_initialize): Remove; no longer needed.
5305 All uses and decls removed.
5307 * emacs.c (fatal_error_signal_hook): Remove.
5308 All uses removed. This leftover from old code was always 0.
5310 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5311 * casefiddle.c (casify_object, casify_region):
5312 * casetab.c (set_case_table):
5313 * category.c, category.h (word_boundary_p):
5314 * category.h (CHAR_HAS_CATEGORY):
5315 Use bool for booleans, instead of int.
5317 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5319 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5321 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5323 On assertion failure, print backtrace if available.
5324 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5325 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5326 * Makefile.in (LIB_EXECINFO): New macro.
5329 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5330 * bytecode.c (exec_byte_code):
5331 * callint.c (check_mark, Fcall_interactively):
5332 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5333 (getenv_internal, sync_process_alive, call_process_exited):
5334 * lisp.h (USE_SAFE_ALLOCA):
5335 Use bool for booleans, instead of int.
5336 * lisp.h, process.h: Adjust prototypes to match above changes.
5337 * callint.c (Fcall_interactively): Don't assume the mark's
5338 offset fits in 'int'.
5340 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5342 * buffer.c, buffer.h: Use bool for boolean.

5349 (mmap_enlarge, mmap_set_vars):
5350 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5351 Use bool for booleans, instead of int.
5352 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5353 since the 1-or-0 return value is always ignored anyway.
5354 (mmap_initialized_p):
5355 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5356 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5358 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5360 * bidi.c: Use bool for boolean.
5361 This is a bit more readable, and makes the text segment of bidi.o
5362 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5363 Presumably it's faster too.
5364 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

5369 (bidi_explicit_dir_char, bidi_level_of_next_char)
5370 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5371 Use bool for booleans, instead of int.
5372 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5373 (bidi_unshelve_cache): Adjust decls to match code.
5375 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5377 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5380 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5382 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5383 * atimer.h: Include <stdbool.h>.
5385 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5387 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5388 compile time tests instead of run time tests on systems that do
5390 (FRAME_MAC_P): Remove leftover from deleted code.
5391 * frame.c (syms_of_frame): Remove leftover from deleted code.
5393 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5395 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5397 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5399 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5400 Otherwise, the compiler complains about (A?B:C) where B is void
5401 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5402 (fontset_add): Return void, for FONTSET_ADD.
5404 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5406 * alloc.c: Use bool for booleans.
5407 (gc_in_progress, abort_on_gc)
5408 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5409 (dont_register_blocks) [GC_MALLOC_CHECK]:
5410 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

5412 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5413 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5414 (mark_stack, valid_pointer_p, make_pure_string)
5415 (Fgarbage_collect, survives_gc_p, gc_sweep):
5416 Use bool for booleans, instead of int.
5417 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5418 Remove unused local.
5419 * alloc.c (PURE_POINTER_P):
5420 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5421 * editfns.c (Fformat):
5422 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5424 * fns.c (sweep_weak_table):
5425 * lisp.h (suppress_checking, push_message, survives_gc_p)
5426 (make_pure_string, gc_in_progress, abort_on_gc):
5427 * lread.c (readchar, read1):
5428 * print.c (Fprin1_to_string):
5429 * xdisp.c (push_message):
5430 Use bool for booleans affected directly or indirectly by
5433 Make recently-introduced setters macros.
5434 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5435 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5436 (set_fontset_default, set_fontset_fallback): Rename from their
5437 upper-case counterparts, and make them functions rather than macros.
5438 This is more consistent with the other recently-introduced setters.
5439 These don't need to be inline, since they're local.
5441 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5443 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5444 the loop (Bug#12247).
5446 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5448 * lisp.h (vcopy): Use memcpy rather than our own loop.
5449 This fixes a performance regression introduced by the recent
5450 addition of vcopy. This means 'vcopy' will need to be modified
5451 for a copying collector, but that's OK. Also, tighten the
5452 checking in the assertion.
5454 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5456 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5457 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5458 non-base glyph for the width of the base character, according to
5459 what x_draw_composite_glyph_string_foreground expects.
5460 Generate WADJUST value according to composition_gstring_width's
5461 expectations, to produce correct width of the composed character.
5462 Reverse the sign of the DU offset produced by ScriptPlace.
5464 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5466 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5468 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5470 Avoid direct writes to contents member of struct Lisp_Vector.
5471 * lisp.h (vcopy): New function to copy data into vector.
5472 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5473 * fns.c (Ffillarray): Use ASET.

5548 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>

5551 as gnulib does this if the system doesn't.
5552 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

6421 2012-08-04 Eli Zaretskii <eliz@gnu.org>
6423 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6424 * w32.c (init_environment): Change the default values of many
6425 environment variables in dflt_envvars[] to NULL, to avoid pushing
6426 them into environment when they were not already defined.
6427 Remove the code that deletes site-lisp subdirectories from the default
6428 value of EMACSLOADPATH, as it is no longer needed.
6429 (check_windows_init_file): Now external, not static.
6430 Use Vload_path as is, without adding anything, as this function is now
6431 called when Vload_path is already set up.
6433 * w32.h (check_windows_init_file): Add prototype.
6435 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
6436 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
6437 compatibility with Posix platforms.
6438 (main): Move the call to check_windows_init_file to here from
6440 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
6441 any, in the DEFALT argument into the root of the Emacs build or
6442 installation tree, as appropriate.
6444 * callproc.c (init_callproc_1): Call decode_env_path instead of
6445 doing its equivalent by hand.
6446 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
6447 the code that sets Vexec_path run on MS-Windows.
6449 * lread.c (init_lread): Add comments to #ifdef's.
6451 * msdos.c (dos_set_window_size, IT_update_begin)

6459 Now constants, not macros.
6461 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
6463 Remove unnecessary casts involving pointers.
6464 These casts are no longer needed now that we assume C89 or later,
6465 since they involve casting to or from void *.
6466 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
6467 (make_pure_float, make_pure_vector):
6468 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

6478 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6479 Remove unnecessary pointer casts.
6480 * alloc.c (record_xmalloc): New function.
6481 * lisp.h (record_xmalloc): New decl.
6482 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6483 more like a function. This is because the pointer cast is not
6484 needed. All uses changed.
6485 * print.c (print_string, print_error_message): Avoid length recalc.
6487 Improve fix for macroexp crash with debugging (Bug#12118).
6488 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6489 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6490 not supposed to be invoked from the garbage collector.
6491 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6492 (gc_aset): New function, which is like ASET but can be
6493 used in the garbage collector.
6494 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

6507 (map_w32_filename): Improve commentary. Simplify switch.
6508 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
6509 headers (most versions of MinGW w32api don't).
6510 (get_security_info, create_symbolic_link)
6511 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
6513 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
6514 in the argument file name.

6517 (sys_rename): Diagnose renaming of a symlink when the user doesn't
6518 have the required privileges.
6519 (get_file_security_desc_by_name): Rename from
6520 get_file_security_desc.

6522 with addition of handling of symlinks and support for 'lstat'.
6523 If possible, get file's attributes and security information by
6524 handle, not by name. Produce S_IFLNK bit for symlinks, when
6525 called from 'lstat'.
6526 (stat, lstat): New functions, call 'stat_worker'.
6527 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6528 symlinks when the underlying filesystem supports them.
6530 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6532 Fix macroexp crash on Windows with debugging (Bug#12118).
6533 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6534 checking subscripts; problem introduced with the recent
6535 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6536 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6537 since it's used in non-static inline functions now.
6539 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6540 Don't assume buffer size fits in 'int'. Remove unused local.

6558 * character.c (CHARACTER_INLINE):
6559 * charset.c (CHARSET_INLINE):
6560 * composite.c (COMPOSITE_INLINE):
6561 * dispnew.c (DISPEXTERN_INLINE):
6562 * sysdep.c (SYSTIME_INLINE):
6563 Define to EXTERN_INLINE, so that the corresponding functions
6564 are compiled into code.
6565 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6566 (INLINE_HEADER_END): New macros.
6567 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6589 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6591 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6592 This how ASET and AREF are supposed to work, and makes
6593 it easier to think about future improvements. See
6594 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6595 * charset.h (set_charset_attr): New function.

6848 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
6849 does that unconditionally. Remove file, which is now empty.
6851 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
6854 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
6856 Export to GDB most of lisp.h's remaining object-like macros.

6869 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
6870 Move to after the definition of struct Lisp_Char_Table,
6871 since the former now needs that type defined.

6972 * w32inevt.c: Include w32inevt.h.
6973 (w32_read_console_input): New inline function, calls either
6974 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
6975 w32_console_unicode_input.
6976 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
6977 (w32_kbd_patch_key, key_event): Use the codepage returned by
6978 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
6979 (key_event): use uChar.UnicodeChar only if
6980 w32_console_unicode_input is non-zero.

7007 * alloc.c (listn): Fix the order the arguments are consed onto the
7010 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7011 enumeration constants, as PURE and HEAP are too general, and clash
7012 with other headers and sources, such as gmalloc.c and the
7013 MS-Windows system headers. All users changed.
7015 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7017 Revert last save_excursion_save and save_excursion_restore changes.
7018 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7028 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
7030 Improve GDB symbol export (Bug#12036).
7031 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7032 arms of an 'if', not using conditional expressions; otherwise GDB
7033 complains about the types in the unevaluated arm when the argument
7034 is an integer literal.
7035 (xgetint): Simplify expression.
7036 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7037 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7038 Zaretskii in <http://bugs.gnu.org/12036#13>.
7039 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7040 needed now that we have gdb_make_enums_visible.
7041 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7042 (enum enum_USE_LSB_TAG):
7043 New enum types, packaging up enums that need to be exported to GDB.

7061 * xdisp.c (syms_of_xdisp): Likewise.
7062 * xfns.c (syms_of_xfns): Likewise.
7064 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7066 Fast save_excursion_save and save_excursion_restore.
7067 * lisp.h (struct Lisp_Excursion): New data type.
7068 (PVEC_EXCURSION): New pseudovector type.
7069 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7070 to deal with it. Adjust comments.

7081 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7083 Fix export of symbols to GDB (Bug#12036).
7084 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
7085 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7086 emacs.c, as this is a more-suitable home. Had this been done earlier
7087 the fix for 12036 would have avoided some of the problems noted in
7088 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7089 would have been more obvious.
7090 * emacs.c: Do not include <verify.h>; no longer needed.
7091 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7092 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7093 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7094 Remove; now done in lisp.h.
7095 * lisp.h (PUBLISH_TO_GDB): New macro.

7098 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7099 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7100 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7101 not be usable in #if. This simplifies things.
7103 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7105 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7107 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

7110 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7111 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7112 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7113 Adjust to changes in lisp.h and emacs.c, by using
7114 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7115 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7116 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7117 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7118 instead of gdb_valbits.
7119 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7120 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7121 instead of gdb_array_mark_flag.
7122 (xboolvector): Get size from $->size, not $->header.size.
7123 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7124 (xreload, hook-run, hookpost-run): Remove.
7125 * emacs.c: Include <verify.h>.
7126 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7127 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7129 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7130 (gdb_USE_LSB_TAG): New enum constants.
7131 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7132 Also define these as enum constants, so they're visible to GDB.
7133 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7134 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7135 as constants, so they're visible to GDB.
7136 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
7137 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
7138 Now enum constants, not macros, so they're visible to GDB.
7139 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7140 more convenient now. All uses changed.
7141 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7142 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7144 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
7146 Explicitly free restriction data that are not needed anymore.
7147 * editfns.c (save_restriction_restore): Free restriction data.
7149 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
7151 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7152 add argument, tune behavior, and adjust all callers.
7154 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7156 Use typedef for EMACS_INT, EMACS_UINT.
7157 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7158 than macros. This simplifies debugging in the usual case, since
7159 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7160 and it allows expressions involving EMACS_INT casts.
7161 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7163 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7171 that FOCUS-FRAME can be omitted.
7173 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7175 Adjust buffer text indirection counters at the end of Fkill_buffer.
7176 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7177 buffer is definitely dead. This should really fix an issue reported
7178 by Christoph Scholtes again. (Bug#12007).
7179 (init_buffer_once): Initialize indirection counters of
7180 buffer_defaults and buffer_local_symbols (for sanity and safety).
7182 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7184 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7185 and continuation glyphs on tooltip frames, leave them at zero.
7186 Avoids continued lines in tooltips. (Bug#11832)
7188 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7190 Simplify copy_overlay.
7191 * buffer.c (copy_overlay): Simplify. Use build_marker.

7197 or invalid. (Bug#12025)
7199 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
7200 it signals an error when a tooltip frame is being created.
7202 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7204 Cleanup miscellaneous objects allocation and initialization.
7205 * alloc.c (allocate_misc): Change to static. Add argument to
7206 specify the subtype. Adjust comment and users.
7207 (build_overlay): New function.
7208 * buffer.c (copy_overlays, Fmake_overlay): Use it.
7209 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
7210 (allocate_misc): Remove prototype.
7211 (build_overlay): Add prototype.
7213 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7215 Swap buffer text indirection counters in Fbuffer_swap_text.
7216 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7217 This avoids crash reported by Christoph Scholtes at
7218 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7220 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7222 * nsmenu.m (Popdown_data): New struct.
7223 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7225 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7226 (initWithContentRect): Make imgView and contentView non-static

7981 The functional style also makes code easier to read and maintain.
7982 * systime.h: Include <sys/time.h> on all hosts, not just if
7983 WINDOWSNT, since 'struct timeval' is needed in general.

8024 Prefer snprintf to strncpy.
8025 * nsterm.m (ns_term_init):
8026 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8027 * nsterm.m (ns_term_init):
8028 Avoid the need for strncpy, by using build_string or
8029 make_unibyte_string directly. Use dtoastr, not snprintf.
8030 * process.c (Fmake_network_process): Diagnose service names that
8031 are too long, rather than silently truncating them or creating
8032 non-null-terminated names.

8049 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8050 where argument type is known to be a Lisp_Cons.

8105 O_RDONLY already includes it).
8107 Stop ns builds setting the EMACSLOADPATH environment variable.
8108 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8109 Now it does not set EMACSLOADPATH, just returns the load-path string.
8110 * nsterm.h: Update accordingly.
8111 * lread.c [HAVE_NS]: Include nsterm.h.
8112 (init_lread) [HAVE_NS]: Use ns_load_path.

8122 (ns_init_paths): Do not set EMACSPATH.

8127 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8129 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8131 * process.c (wait_reading_process_output): 'waitchannels' was unset
8132 when read_kbd || !NILP (wait_for_cell); fix this.
8134 Add GCC-style 'const' attribute to functions that can use it.
8135 * character.h (char_resolve_modifier_mask):
8136 * keyboard.h (make_ctrl_char):
8137 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8138 (init_character_once, next_almost_prime, init_fns, init_image)
8139 (flush_pending_output, init_sound):

8144 Declare the dummy function with ATTRIBUTE_CONST.
8145 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8146 Add decls with ATTRIBUTE_CONST.
8148 Minor improvements to make_formatted_string.
8149 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8150 where int is good enough, as vsprintf returns an int.
8151 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8153 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8155 Use make_formatted_string to avoid double length calculation.
8156 * lisp.h (make_formatted_string): New prototype.
8157 * alloc.c (make_formatted_string): New function.
8158 * buffer.c (Fgenerate_new_buffer_name): Use it.

8161 * filelock.c (get_boot_time): Likewise.
8162 * frame.c (make_terminal_frame, set_term_frame_name)
8163 (x_report_frame_params): Likewise.
8164 * image.c (gs_load): Likewise.

8176 * nsterm.h (ns_etc_directory): Add it.
8177 * callproc.c [HAVE_NS]: Include nsterm.h.
8178 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
8180 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8182 Move marker debugging code under MARKER_DEBUG.
8183 * marker.c (MARKER_DEBUG): Move marker debugging code under
8184 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8185 for bootstrap with --enable-checking (~3x slowdown reported
8186 by Juanma Barranquero <lekktu@gmail.com>).
8187 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8189 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8191 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8192 See <http://bugs.gnu.org/11825#29>.
8194 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8196 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8197 has no font, use the frame's font. (Bug#11813)
8198 (display_line): Add commentary about displaying truncation glyphs
8200 (produce_special_glyphs): Move here from term.c.
8202 * term.c (produce_special_glyphs): Move to xdisp.c.
8204 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8207 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8209 * xdisp.c (display_line): Avoid warning about implicit declaration
8212 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8214 * lisp.h: Remove empty conditional.
8216 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8218 * lread.c (load_path_check): Now static.
8220 Fix some minor --with-ns problems found by static checking.
8221 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8222 (x_set_font) [!HAVE_X_WINDOWS]:
8223 * image.c (xpm_load_image) [HAVE_NS]:
8224 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8225 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8226 Remove unused local.
8227 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8228 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8229 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8230 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8231 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8232 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8233 Fix pointer signedness problem.
8234 * xfaces.c (FRAME_X_FONT_TABLE):
8235 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8237 2012-07-07 Glenn Morris <rgm@gnu.org>
8239 * lread.c (load_path_check): New function, split from init_lread.
8240 (init_lread): Reorganize. Motivation:
8241 If EMACSLOADPATH is set, check/warn about that rather than the
8242 defaults, which we are not going to use. Hence we can remove
8243 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8244 Don't warn if site-lisp directories are missing.
8245 If not installed, start from a blank load-path, since
8246 PATH_LOADSEARCH refers to the eventual installation directories.
8248 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8250 Support truncation and continuation glyphs on GUI frames, when
8251 fringes are disabled. (Bug#11832)
8252 * xdisp.c (init_iterator): Get dimensions of truncation and
8253 continuation glyphs even if on GUI frames.
8254 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8255 or both, are absent.
8256 (start_display, move_it_in_display_line_to): Handle the case of a
8257 GUI frame without a fringe to display continuation or truncation
8259 (insert_left_trunc_glyphs): Support GUI frames: make sure
8260 truncation glyphs overwrite enough glyphs from the current line to
8261 have sufficient space in pixels.
8262 (display_line): Support truncation and continuation glyphs on GUI
8263 frames. If some spare pixels are left on the line after inserting
8264 the truncation glyphs, fill that space with a stretch glyph of a
8265 suitably computed width.
8267 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8268 produce_glyphs, to support GUI sessions.
8270 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8272 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8274 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8276 Do not require float-time's arg to fit in time_t (Bug#11825).
8277 This works better on hosts where time_t is unsigned, and where
8278 float-time is applied to the (negative) difference between two times.
8279 * editfns.c (decode_time_components): Last arg is now double *,
8280 not int *, and means to store all the result as a double, without
8281 worrying about whether the seconds part fits in time_t.
8282 All callers changed.
8283 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8284 All callers changed.
8285 (Ffloat_time): Do not fail merely because the specified time falls
8286 outside of time_t range.
8288 2012-07-07 Glenn Morris <rgm@gnu.org>
8290 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8297 Update dependencies.
8299 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8301 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8303 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

8305 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8306 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8307 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

8310 * xfont.c (compare_font_names): Redo to omit the need for casts.
8312 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8314 * xfns.c (Fx_change_window_property): Doc fix.
8315 * w32fns.c (Fx_change_window_property): Doc fix.
8317 * w32fns.c (Fx_window_property): Accept the same arguments as the
8318 X Windows version. Doc fix.
8319 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8321 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8322 Eli Zaretskii <eliz@gnu.org>
8324 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8325 Windows-specific code from nt/config.nt moved here.
8326 Obsolete settings removed.
8328 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8330 * process.c: Avoid unnecessary calls to gettime.
8331 (wait_reading_process_output): Don't get the time of day
8332 when gobbling data immediately and not waiting, as there's no need
8333 for it in that case. This removes a FIXME.
8335 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8337 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8338 is defined (Bug#11768).
8340 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8342 Fix marker debugging code.
8343 * marker.c (byte_char_debug_check): Do not perform the check
8344 if buffer is not multibyte.
8345 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8346 Call byte_char_debug_check with correct arguments.
8348 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8350 Compile marker debugging code only if ENABLE_CHECKING is defined.
8351 * marker.c (byte_char_debug_check, count_markers):
8352 Use only if ENABLE_CHECKING is defined.
8353 (byte_debug_flag): Remove.
8354 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8355 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8357 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8359 Avoid code repetition in marker-related functions.
8360 * marker.c (attach_marker): New function.
8361 (Fset_marker, set_marker_restricted, set_marker_both)
8362 (set_marker_restricted_both): Use it.
8363 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8364 Consistently rename charno to charpos.
8365 (marker_position): Add eassert.
8366 (marker_byte_position): Convert to eassert.

8381 * editfns.c (buildmark): Remove.
8382 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
8383 (save_restriction_save): Use build_marker.
8384 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8385 * window.c (save_window_save): Likewise.
8387 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8389 Do not use Fdelete_overlay in delete_all_overlays
8390 to avoid redundant calls to unchain_overlay.
8391 * buffer.c (drop_overlay): New function.
8392 (delete_all_overlays, Fdelete_overlay): Use it.
8393 * minibuf.c (get_minibuffer): Fix comment.
8395 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8397 Port to OpenBSD 5.1 amd64.
8398 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8399 This is needed for OpenBSD, and should be harmless on all BSD systems.
8400 Also, include <sys/sysctl.h>, as it should be available on all
8401 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8402 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8403 use p_pid member, not kp_proc.pid.
8405 2012-07-06 Glenn Morris <rgm@gnu.org>
8407 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8409 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8411 More xmalloc and related cleanup.
8412 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8413 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
8414 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

8418 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
8419 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
8420 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8422 Omit needless casts involving void * pointers and allocation.
8423 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8424 as the former is more robust if P's type is changed.
8425 Prefer xzalloc to xmalloc + memset 0.
8426 Simplify malloc-or-realloc to realloc.
8427 Don't worry about xmalloc returning a null pointer.
8428 Prefer xstrdup to xmalloc + strcpy.
8429 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8431 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8432 alloca of a constant.
8434 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8436 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8437 hscroll is larger than the line width. Fixes long and futile
8438 looping inside extend_face_to_end_of_line (on a TTY) producing
8439 glyphs that are not needed and thrown away.
8441 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8443 * marker.c (set_marker_restricted_both): Simplify by using

8457 followed by gtk_box_set_homogeneous (Bug#11768).
8458 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8459 (update_theme_scrollbar_width, xg_create_scroll_bar):
8460 Use gtk_scrollbar_new (Bug#11768).
8461 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8462 (is_box_type): New function (Bug#11768).
8463 (xg_tool_item_stale_p): Call is_box_type.
8464 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8465 with default display (Bug#11768).
8467 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8469 * xdisp.c (window_hscroll_limited): New function.
8470 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8471 coordinates when window's hscroll is set to insanely large
8474 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8476 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8477 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

8543 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8544 This should be fixed in a better way; see Eli Zaretskii in
8545 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8546 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8548 * fileio.c (time_error_value): Rename from special_mtime.
8549 The old name's problems were noted by Eli Zaretskii in
8550 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8552 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8553 This variable's comment says Emacs needs at least one GDB-visible
8554 symbol of type enum pvec_type, to work around GDB problems.
8555 The symbol's value doesn't matter.
8557 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8558 that causes compilation to fail on pre-C99 compilers.
8560 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

8584 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8585 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8586 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8587 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8588 abusing vector->header.next.nbytes.
8589 (live_vector_p): Use PVEC_TYPE.
8590 (mark_object): Adapt code to extract pvectype. Use switch.
8592 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8594 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8595 Tighten new eassert a bit.
8597 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8599 Fix compilation with --enable-gcc-warnings and -O1
8601 * doprnt.c (doprnt): Change type of tem to int, initialize
8602 to avoid compiler warning. Add eassert.
8603 * search.c (simple_search): Initialize match_byte to avoid
8604 compiler warning. Add eassert.
8606 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8608 Avoid weird behavior with large horizontal scrolls.
8609 Without this change, for example, large hscroll values would
8610 mess up Emacs's display on Fedora 15 x86, presumably due to
8611 overflows in int calculations in the display code.
8612 Also, if buffers had long lines, Emacs would freeze.
8613 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8614 (set_window_hscroll): New function, containing the old guts of
8615 Fset_window_hscroll. Return the clipped value.
8616 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8617 This avoids the need to check against PTRDIFF_MAX.
8619 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8621 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8623 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8625 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8627 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8628 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8629 since GCC 4.4.6 issues a bogus warning for them.
8631 Fix bugs in file timestamp newness comparisons.
8632 * fileio.c (Ffile_newer_than_file_p):
8633 * lread.c (Fload): Use full timestamp resolution of files,
8634 not just the 1-second resolution, so that files that are only
8635 slightly newer still count as newer.
8636 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8637 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8639 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8641 * fileio.c: Improve handling of file time marker. (Bug#11852)
8642 (special_mtime): New function.
8643 (Finsert_file_contents, Fverify_visited_file_modtime):
8644 Use it to set special mtime values consistently.
8646 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8648 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8649 marker for non-existing file. (Bug#11852)
8651 2012-07-03 Glenn Morris <rgm@gnu.org>
8653 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8654 and did not make it into globals.h).
8656 2012-07-03 Tom Tromey <tromey@redhat.com>
8658 * window.c (Fset_window_margins, Fset_window_fringes)
8659 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8660 * textprop.c (Fprevious_property_change): No longer static.
8661 * syntax.c (Fsyntax_table_p): No longer static.
8662 * process.c (Fget_process, Fprocess_datagram_address): No longer

8674 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): No longer
8676 * dired.c (Ffile_attributes): No longer static.
8677 * composite.c (Fcomposition_get_gstring): No longer static.
8678 * callproc.c (Fgetenv_internal): No longer static.
8680 * ccl.h: Remove EXFUNs.
8681 * buffer.h: Remove EXFUNs.
8682 * dispextern.h: Remove EXFUNs.
8683 * intervals.h: Remove EXFUNs.
8684 * fontset.h: Remove EXFUN.
8685 * font.h: Remove EXFUNs.
8686 * dosfns.c (system_process_attributes): Remove EXFUN.
8687 * keymap.h: Remove EXFUNs.
8688 * lisp.h: Remove EXFUNs.
8689 * w32term.h: Remove EXFUNs.
8690 * window.h: Remove EXFUNs.
8691 * xsettings.h: Remove EXFUN.
8692 * xterm.h: Remove EXFUN.
8694 2012-07-03 Glenn Morris <rgm@gnu.org>
8696 * lisp.h (Frandom): Make it visible to C.
8697 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8698 buffer for invisible buffers. (Bug#1229)
8700 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8702 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8703 values which aren't power of 2.
8704 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8705 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8708 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8710 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8712 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8714 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8716 * alloc.c (allocate_vector_block): Remove redundant
8717 calls to mallopt if DOUG_LEA_MALLOC is defined.
8718 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8719 avoid calls to mallopt if zero_vector is returned.
8721 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8723 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8724 is enabled, avoid dereferencing NULL current_sblock if
8727 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8729 Cleanup basic buffer management.
8730 * buffer.h (struct buffer): Change layout to use generic vector
8731 marking code. Fix some comments. Change type of 'clip_changed'
8732 to bitfield. Remove unused #ifndef old.
8733 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8734 (GET_OVERLAYS_AT): Fix indentation.
8735 (for_each_per_buffer_object_at): New macro.
8736 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8737 (Fbuffer_local_variables): Use it.
8738 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8739 * alloc.c (allocate_buffer): Adjust to match new layout of
8740 struct buffer. Fix comment.
8741 (mark_overlay): New function.
8742 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8743 Lisp area of struct buffer.
8744 (mark_object): Use it. Adjust marking of misc objects
8745 and related comments.
8747 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8749 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8750 wrapper that is not needed because the wrapped code is a no-op (zero
8751 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8752 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8754 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8756 * alloc.c (mark_buffer): Simplify. Remove prototype.
8757 (mark_object): Add comment. Reorganize marking of vector-like
8758 objects. Use CHECK_LIVE for all vector-like objects except buffers
8759 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8760 Avoid redundant calls to mark_vectorlike for bool vectors.
8762 2012-06-30 Glenn Morris <rgm@gnu.org>
8764 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8766 * epaths.in (PATH_SITELOADSEARCH): New.
8767 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8768 This is rather than relying on --enable-locallisppath elements
8769 having "site-lisp" in their names. (Bug#10208#25, 11658)
8771 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8773 * w32proc.c (sys_select): Accept and ignore one more argument.
8775 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8777 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8778 (pselect) [!MS_DOS]: Redirect to sys_select.
8780 * sysdep.c: Don't include dos.h and dosfns.h.
8782 * process.c (sys_select):
8783 * msdos.c (sys_select): Accept one more argument and ignore it.
8785 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8786 adapt data types and code to that.
8789 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8790 which clashes with the gnulib function of the same name.
8792 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8794 * font.c (font_style_to_value, font_style_symbolic)
8795 (font_prop_validate_style): Add type checks for values in
8798 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8800 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8803 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8805 * xdisp.c (try_window_id): Undo last change.
8807 * w32.c (getwd): Adjust commentary about startup_dir.
8808 (init_environment): Always call sys_access, even in non-MSVC
8809 builds. Don't chdir to the directory of the Emacs executable.
8810 This undoes code from 1997 which was justified by the need to
8811 "avoid conflicts when removing and renaming directories". But its
8812 downside was that every relative file name was being interpreted
8813 relative to the directory of the Emacs executable, which can never
8814 be TRT. In particular, it broke sys_access when called with
8815 relative file names.
8816 (sys_access): Map GetLastError to errno.
8818 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8820 * window.h (struct window): Change type of 'fringes_outside_margins'

8824 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8827 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8829 * gnutls.c (emacs_gnutls_handshake):
8830 Add QUIT to make the loop interruptible.
8832 2012-06-29 Glenn Morris <rgm@gnu.org>
8834 * charset.c (init_charset): Make lack of etc/charsets fatal.
8836 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8838 * editfns.c (region_limit): Fix type mismatch.
8840 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8842 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8843 undefined. Convert from xassert to eassert.
8844 * nsmenu.m: Convert from xassert to eassert.
8845 * nsterm.m: Likewise.
8847 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8849 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8851 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8853 Avoid integer overflow on scroll-left and scroll-right.
8854 * window.c (HSCROLL_MAX): New macro.
8855 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8856 overflow when requested scroll falls outside ptrdiff_t range.
8858 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8860 * window.h (struct window): Change type of 'hscroll',
8861 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8862 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8863 Adjust users accordingly.
8864 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8865 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8866 from EMACS_INT to ptrdiff_t.
8867 (make_window): Omit redundant initialization.
8869 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

8873 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8875 * window.h (struct window): Change type of 'use_time' and
8876 'sequence_number' from Lisp_Object to int.

8886 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8887 adjust comments accordingly.

8936 * alloc.c (allocate_string_data): Remove dead code.
8937 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
8938 avoid GCC warning about unused macro.
8940 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8942 * alloc.c (allocate_string): Omit intervals initialization.
8943 * alloc.c (make_uninit_multibyte_string): Initialize intervals
8944 as in make_pure_string and make_pure_c_string.
8946 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8948 * alloc.c (allocate_string): Fix last change.
8950 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9000 * alloc.c: Remove build_string.
9001 * lisp.h: Define build_string as static inline. This provides
9002 a better opportunity to optimize away calls to strlen when the
9003 function is called with compile-time constant argument.
9004 * image.c (imagemagick_error): Convert to build_string.
9005 * w32proc.c (sys_spawnve): Likewise.
9006 * xterm.c (x_term_init): Likewise.
9008 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9010 Use sprintf return value instead of invoking strlen on result.
9011 In the old days this wasn't portable, since some sprintf
9012 implementations returned char *. But they died out years ago and
9013 Emacs already assumes sprintf returns int.
9014 Similarly for float_to_string.
9015 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9016 * ccl.c (ccl_driver):
9017 * character.c (string_escape_byte8):

9020 * print.c (print_object):
9021 * xdisp.c (message_dolog):
9022 * xfns.c (syms_of_xfns):
9023 Use sprintf or float_to_string result to avoid need to call strlen.
9024 * data.c (Fnumber_to_string):
9025 Use make_unibyte_string, since the string must be ASCII.
9026 * lisp.h, print.c (float_to_string): Now returns int length.
9027 * term.c (produce_glyphless_glyph):
9028 Use sprintf result rather than recomputing it.
9030 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9031 * Makefile.in (ALL_CFLAGS):
9032 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

9038 strcasecmp if available.

9054 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9056 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9057 sprintf already null-terminates its output.

9061 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9063 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

9066 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9068 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9069 instead of truncating it to 63 (admittedly a generous limit).
9071 * process.c: Fix spelling and caps in comments.
9073 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9075 * emacs.c (setpgrp): Remove definition, unused.

9085 (SYSTIME_H): Add nt/inc/sys/time.h.
9087 * systime.h [WINDOWSNT]: Include sys/time.h.

9199 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9201 Support higher-resolution time stamps (Bug#9000).
9202 The time stamps are only nanosecond-resolution at the C level,
9203 since that's the best that any real-world system supports now.
9204 But they are picosecond-resolution at the Lisp level, as that's
9205 easy, and leaves room for future OS improvements.
9207 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9210 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9211 Don't get current time unless it's needed.
9213 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9214 now provides it if it's absent.
9215 (start_atimer): Port to higher-res time stamps.
9216 Check for time stamp overflow. Don't get current time more
9217 often than is needed.
9219 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9220 Include systime.h, not time.h.
9221 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9223 * dired.c: Include stat-time.h.
9224 (Ffile-attributes): File times now have higher resolution.

9227 (struct image): Timestamp now has higher resolution.
9229 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9230 has at least microseconds now. All uses removed.
9231 (update_frame, update_single_window, update_window, update_frame_1)
9232 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9233 (duration_to_sec_usec): Remove; no longer needed.
9235 * editfns.c (time_overflow): Now extern.

9241 (decode_time_components, lisp_seconds_argument): New functions.
9242 (make_time): Now static.
9243 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9244 Report an error if the time is invalid, rather than having the caller
9247 * fileio.c: Include <stat-time.h>
9248 (Fcopy_file): Copy higher-resolution time stamps.
9249 Prefer to set the time stamp via a file descriptor if that works.

9251 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9252 (Fvisited_file_modtime, Fset_visited_file_modtime):
9253 Support higher-resolution time stamps.
9255 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9257 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9259 * image.c (prepare_image_for_display, clear_image_cache)
9260 (lookup_image): Port to higer-resolution time stamps.
9262 * keyboard.c (start_polling, bind_polling_period):
9263 Check for time stamp overflow.
9264 (read_char, kbd_buffer_get_event, timer_start_idle)
9265 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9266 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9267 Port to higher-resolution time stamps. Do not assume time_t is signed.
9268 (decode_timer): New function. Timers are now vectors of length 9,
9269 not 8, to accommodate the picosecond component.
9270 (timer_check_2): Use it.
9272 * nsterm.m (select_timeout, timeval_subtract): Remove.
9273 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9274 as they're a bit more accurate and handle overflow better.
9275 (ns_select): Change prototype to be compatible with pselect.
9276 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9277 * nsterm.h (ns_select): Adjust prototype.
9279 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9280 us-resolution time stamps.
9281 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9283 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9285 * lisp.h (time_overflow): New decl.
9286 (wait_reading_process_output): First arg is now intmax_t, not int,
9287 to accommodate larger waits.
9289 * process.h (struct Lisp_Process.read_output_delay):
9290 Now counts nanoseconds, not microseconds.
9291 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9293 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9294 (wait_reading_process_output):
9295 Port to ns-resolution time stamps.
9296 (Faccept_process_output, wait_reading_process_output):
9297 Check for time stamp overflow. Do not assume time_t is signed.
9298 (select_wrapper): Remove; we now use pselect.
9299 (Fprocess_attributes): Now generates ns-resolution time stamps.
9301 * sysdep.c: Include utimens.h. Don't include utime.h
9302 or worry about struct utimbuf; gnulib does that for us now.
9303 (gettimeofday): Remove; gnulib provides a substitute.
9304 (make_timeval): New function.
9305 (set_file_times): Now sets ns-resolution time stamps.
9306 New arg FD; all uses changed.
9307 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9308 (system_process_attributes):
9309 Now returns ns-resolution time stamp. All uses changed.
9310 Check for time stamp overflow.
9312 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9313 provides a substitute now.
9315 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9316 since it guarantees struct timespec.
9317 (EMACS_TIME): Now struct timespec, so that we can support
9318 ns-resolution time stamps.
9319 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9320 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9321 (EMACS_USECS): Remove.
9322 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9323 so multiply the arg by 1000 before storing it.
9324 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9326 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9327 Port to ns-resolution time stamps.
9328 (EMACS_TIME_NEG_P): Remove; replaced by....
9329 (EMACS_TIME_SIGN): New macro.
9330 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9331 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9332 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9333 (make_timeval, make_lisp_time, decode_time_components): New decls.
9334 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9335 that it mishandled time_t overflow. You can't compare by subtracting!
9336 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9337 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9339 * term.c: Include <sys/time.h>.
9340 (timeval_to_Time): New function, for proper overflow wraparound.

9345 (Fprimitive_undo): Use them when restoring time stamps.
9347 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9348 (w32_get_internal_run_time):
9349 Port to higher-resolution Emacs time stamps.
9350 (ltime): Now accepts single 64-bit integer, as that's more convenient
9353 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9355 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9356 for compatibility with pselect. Support ns-resolution time stamps.
9358 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9360 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9361 Check for time stamp overflow, and support ns-resolution time stamps.
9363 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9364 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9365 (timeval_subtract): Remove; no longer needed.
9366 (XTflash, XTring_bell, x_wait_for_event):
9367 Port to ns-resolution time stamps. Don't assume time_t is signed.
9369 2012-06-22 Chong Yidong <cyd@gnu.org>
9371 * xdisp.c (x_consider_frame_title): Revert last change.
9373 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9375 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9376 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9377 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9378 staticidx goes up to 1597 out of 1600 = 0x640.)
9380 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9382 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9383 Otherwise, the umask might be mistakenly 0 while handling input signals.

9394 access to `contents' member of Lisp_Vector objects with AREF and ASET
9397 2012-06-19 Chong Yidong <cyd@gnu.org>
9399 * frame.c (delete_frame): When selecting a frame on a different

9404 (unwind_format_mode_line): Restore them.
9405 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9407 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9408 since tty frames can be explicitly named.
9409 (prepare_menu_bars): Likewise.
9411 * term.c (Ftty_top_frame): New function.
9413 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

9417 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9418 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9419 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9420 (METER_1, METER_2): Simplify.
9422 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

9426 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9428 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9429 gets killed during executing of this function (Bug#11665).
9430 Try to always return Qt when the buffer has been actually killed.
9431 (Vkill_buffer_query_functions): In doc-string say that functions
9432 run by this hook should not change the current buffer.
9434 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9436 Fix recently-introduced process.c problems found by static checking.

9454 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
9456 * lisp.h (eassert): Assume C89 or later.
9457 This removes the need for CHECK.
9458 (CHECK): Remove. Its comments about always evaluating its
9459 argument were confusing, as 'eassert' typically does not evaluate
9462 * coding.c (produce_chars): Use ptrdiff_t, not int.
9464 * xterm.c (x_draw_underwave): Check for integer overflow.
9465 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9649 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
9650 code works fine either way, and efficiency is not a concern here,
9651 as the union type is for debugging, not for production.
9652 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9653 Use an inline function on all platforms when using the union type,
9654 since this is simpler and 'static inline' can be used portably
9656 (LISP_INITIALLY_ZERO): New macro.
9657 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
9658 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

9740 * xdisp.c (vmessage): Treat frame message as multibyte.
9741 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))

9761 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
9763 2012-06-08 Eli Zaretskii <eliz@gnu.org>
9765 * alloc.c (allocate_vectorlike): Fix last change.

9796 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9798 * doprnt.c (doprnt): Truncate multibyte char correctly.
9799 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9800 would mishandle a string argument "Xc" if X was a multibyte
9801 character of length 2: it would truncate after X's first byte
9802 rather than including all of X.
9804 2012-06-06 Chong Yidong <cyd@gnu.org>
9806 * buffer.c (word_wrap): Doc fix.

9855 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9856 Convert pctcpu and pctmem to Lisp float properly.
9857 Let the compiler fold better, as 100.0/0x8000 is exact.
9859 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9861 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9864 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9866 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9868 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>

9871 bitfields where appropriate, remove unused fields.
9872 * window.h (struct window): Remove unused 'last_mark_x' and
9873 'last_mark_y' fields. Rename 'mini_p' field to 'mini',

9876 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9877 fields from Lisp_Object to bitfield. Adjust users accordingly.

9885 and 'double' in a couple of places.
9887 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9889 * xdisp.c (handle_stop): Detect whether we have overlay strings
9890 loaded by testing it->current.overlay_string_index to be
9891 non-negative, instead of checking whether n_overlay_strings is
9892 positive. (Bug#11587)
9894 2012-05-31 Chong Yidong <cyd@gnu.org>
9896 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

9902 * search.c (search_buffer): Remove calls to
9903 r_alloc_inhibit_buffer_relocation, as it is now called by
9904 maybe_unify_char, which was the cause of relocation of buffer text
9907 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9909 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9910 for the duration of call to load_charset, to avoid problems with
9911 callers of maybe_unify_char that access buffer text through C
9914 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9915 decrement the inhibition flag, instead of just setting or
9918 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9920 Remove obsolete '#define static' cruft.
9921 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9922 This #undef was "temporary" in 2000; it is no longer needed
9923 now that '#define static' has gone away.
9924 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9925 (gray_bitmap_bits): Remove; no longer needed.
9926 All uses replaced with definiens.

9970 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9971 Bug#9642, but explicitly check that the buffer the overlay would
9972 be moved to is live and rearrange lines to make sure that errors
9973 will not put the overlay in an inconsistent state.
9974 (Fdelete_overlay): Cosmetics.
9976 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9978 * w32term.c (my_bring_window_to_top): New function.

10032 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10033 they are now on lisp.h.
10035 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10037 * search.c (search_buffer): Use it to inhibit relocation of buffer
10038 text while re_search_2 is doing its job, because re_search_2 is
10039 passed C pointers to buffer text. (Bug#11519)
10041 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10042 Update value to 24.
10044 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10045 state after an additional call to move_it_in_display_line_to, keep
10046 the values of it->max_ascent and it->max_descent found for the
10048 (pos_visible_p): Revert the comparison against bottom_y to what it
10049 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.

10054 Fix coding-related core dumps with gcc -ftrapv.
10055 The code was computing A - B, where A and B are pointers, and B is
10056 random garbage. This can lead to core dumps on platforms that
10057 have special pointer registers, and it also leads to core dumps on
10058 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10059 A - B only when B is initialized properly.
10060 * coding.c (coding_set_source, coding_set_destination): Return void.
10061 (coding_change_source, coding_change_destinations): New functions,
10062 with the old behaviors of coding_set_source and coding_set_destination.
10063 All callers that need an offset changed to use these new functions.
10065 2012-05-26 Glenn Morris <rgm@gnu.org>

10080 * w32inevt.c: Include termchar.h and window.h.
10081 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10082 moves, call note_mouse_highlight. If help_echo changed, call
10083 gen_help_event to produce help-echo message in the echo area.
10084 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10087 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10089 * lread.c (read1): Simplify slightly to avoid an overflow warning
10090 with GCC 4.7.0 on x86-64.
10092 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10094 * bidi.c (bidi_mirror_char): Revert last change: an int is
10095 definitely wide enough here.
10097 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

10115 int might not be wide enough.

10131 (Foverlay_recenter, last_overlay_modification_hooks_used)
10132 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10133 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10134 (validate_region): Omit unnecessary test for b <= e,
10135 since that's guaranteed by the previous test.
10136 (adjust_overlays_for_delete): Avoid pos + length overflow.
10137 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10138 (report_overlay_modification):
10139 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10140 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10141 Omit pointer cast, which isn't needed anyway, and doesn't work
10142 after the EMACS_INT -> ptrdiff_t change.
10143 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10144 * buffer.h: Adjust decls to match defn changes elsewhere.

10147 Use EMACS_INT, not int, where int might not be wide enough.
10148 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10149 not int, to avoid needless 32-bit limit on 64-bit hosts.
10150 (exec_byte_code): Use tighter memory-full test, one that checks
10151 for alloca overflow. Don't compute the address of the object just
10152 before an array, as that's not portable. Use EMACS_INT, not
10153 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10154 * callint.c (Fcall_interactively):
10155 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10156 * callproc.c (call_process_kill, Fcall_process):
10157 Don't assume pid_t fits into an Emacs fixnum.

10167 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10168 (casify_object): Avoid integer overflow when overallocating buffer.
10169 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10170 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10171 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10172 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10173 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10174 integers are now checked earlier. All uses replaced with XINT.
10176 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10177 For CCL_MapSingle, check that content and value are in int range.

10179 Check that Vcode_version_map_vector is a vector.
10180 (resolve_symbol_ccl_program): Check that vector header is in range.
10181 Always copy the vector, so that we can check its contents reliably
10182 now rather than having to recheck each instruction as it's being
10183 executed. Check that vector words fit in 'int'.
10184 (ccl_get_compiled_code, Fregister_ccl_program)
10185 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10186 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10187 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10188 contents are in range.
10189 (Fccl_execute_on_string): Check that status is in range.
10190 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10191 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10192 Accept and return EMACS_INT, not int, because callers can pass values
10193 out of 'int' range.

10199 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10200 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10201 avoid mishandling large integers.
10202 * character.h: Adjust decls to match defn changes elsewhere.
10203 * charset.c (load_charset_map_from_file, find_charsets_in_text)

10210 Remove now-unnecessary CHECK_NATNUMs.
10211 (Fdefine_charset_internal): Check ranges here, more carefully.
10212 Don't rely on undefined behavior with signed left shift overflow.
10213 Don't assume unsigned int fits into fixnum, or that fixnum fits
10214 into unsigned int. Don't require max_code to be a valid fixnum;
10215 that's not true for gb10830 4-byte on a 32-bit host. Allow
10216 invalid_code to be a cons, for the same reason. Require code_offset
10217 to be a character. Avoid int overflow if max_char is close
10219 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10220 this is intended anyway and avoids some undefined behavior.
10221 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10222 INDEX_TO_CODE_POINT, as that's what it expects.
10223 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10224 * charset.h (DECODE_CHAR): Return int, not unsigned;
10225 this is what was intended anyway, and it avoids undefined behavior.
10226 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10227 integer-overflow issues.
10228 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10229 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10230 where the argument is EMACS_INT, and this behavior is not intended.
10231 * chartab.c (Fmake_char_table, Fset_char_table_range)
10232 (uniprop_get_decoder, uniprop_get_encoder):
10233 Don't assume fixnum fits in int.
10234 * cmds.c (move_point): New function, that does the gist of
10235 Fforward_char and Fbackward_char, but does so while checking
10236 for integer overflow more accurately.
10237 (Fforward_char, Fbackward_char): Use it.
10238 (Fforward_line, Fend_of_line, internal_self_insert)
10239 (internal_self_insert):
10240 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11021 2012-05-14 Glenn Morris <rgm@gnu.org>

11028 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

11031 (report_error, report_error_1, make_hdr, copy_sym)
11032 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11033 Make arguments const char *, not char *, to avoid violations of C
11034 standard and to fix some AIX warnings reported by Gilles Pion.
11036 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11038 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11039 already have overlays loaded.
11040 (handle_single_display_spec): Before returning without displaying
11041 fringe bitmap, synchronize the bidi iterator with the main display
11042 iterator, by calling iterate_out_of_display_property.
11043 (iterate_out_of_display_property): Detect buffer iteration by
11044 testing that it->string is a Lisp string.
11045 (get_next_display_element): When the current object is exhausted,
11046 and there's something on it->stack, call set_iterator_to_next to
11047 proceed with what's on the stack, instead of returning zero.
11048 (set_iterator_to_next): If called at the end of a Lisp string,
11049 proceed to consider_string_end without incrementing string
11050 position. Don't increment display vector index past the end of
11051 the display vector. (Bug#11417)
11052 (pos_visible_p): Don't report a position visible when move_it_to
11053 stopped at the last line of window, which happens to be scanned
11054 backwards by the bidi iteration. (Bug#11464)
11056 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11058 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11059 and right-margin display specs even if the spec is invalid or we
11060 are on a TTY, and thus unable to display on the fringes.
11061 That's because the text with the property will not be displayed anyway,
11062 so we need to signal to the caller that this is a "replacing"
11063 display spec. This fixes display when the spec is invalid or we
11066 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11068 * unexaix.c (make_hdr): Fix typo in prototype.
11069 This bug broke the build on AIX. Problem reported by Gilles Pion.

11084 2012-05-12 Glenn Morris <rgm@gnu.org>
11086 * Makefile.in (MKDIR_P): New, set by configure.
11087 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.

11098 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11099 Update dependencies.
11101 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11103 * xgselect.c (xg_select): Put maxfds+1 into a var.
11104 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11106 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11108 2012-05-10 Dave Abrahams <dave@boostpro.com>
11110 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11111 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11113 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11115 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11116 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11117 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11118 Initialize xd_registered_buses.
11120 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11122 Untag more efficiently if USE_LSB_TAG.
11123 This is based on a proposal by YAMAMOTO Mitsuharu in
11124 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11125 For an admittedly artificial (nth 8000 longlist) benchmark on
11126 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11127 Emacs's overall text size by 1%.
11128 * lisp.h (XUNTAG): New macro.
11129 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11130 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11131 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11132 * eval.c (Fautoload):
11133 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11134 * frame.h (XFRAME): Use XUNTAG.
11136 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11137 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11138 Remove unportable assumptions about print widths of types like
11140 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11141 intptr_t when converting between pointer and integer, to avoid GCC
11142 warnings about wrong width.
11144 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11146 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11147 stack for each reader_thread, instead of defaulting to 8MB
11148 determined by the linker. This avoids failures in creating
11149 subprocesses on Windows 7, see the discussion in this thread:
11150 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11152 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11154 Fix up display of the *Minibuf-0* buffer in the mini window.
11155 * keyboard.c (read_char): Don't clear the echo area if there's no
11157 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11158 contents of *Minibuf-0*) if there's no message displayed in its stead.
11160 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11162 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11165 2012-05-06 Chong Yidong <cyd@gnu.org>
11167 * lisp.mk (lisp): Update.
11169 2012-05-05 Jim Meyering <meyering@redhat.com>
11171 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11173 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11175 * data.c (PUT_ERROR): New macro.
11176 (syms_of_data): Use it. Add new error type `user-error'.
11177 * undo.c (user_error): New function.
11178 (Fprimitive_undo): Use it.
11179 * print.c (print_error_message): Adjust print style for `user-error'.
11180 * keyboard.c (user_error): New function.
11181 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11183 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11185 Do not limit current-time-string to years 1000..9999.
11186 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11187 (Fcurrent_time_string): Support any year that is supported by the
11188 underlying localtime representation. Don't use asctime, as it
11189 has undefined behavior for years outside the range -999..9999.
11191 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11193 Fix race conditions involving setenv, gmtime, localtime, asctime.
11194 Without this fix, interrupts could mess up code that uses these
11195 nonreentrant functions, since setting TZ invalidates existing
11196 tm_zone or tzname values, and since most of these functions return
11197 pointers to static storage.
11198 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11199 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11200 Grow the critical sections to include not just invoking
11201 localtime/gmtime, but also accessing these functions' results
11202 including their tm_zone values if any, and any related TZ setting.
11203 (format_time_string): Last arg is now struct tm *, not struct tm **,
11204 so that the struct tm is saved in the critical section.
11205 All callers changed. Simplify allocation of initial buffer, partly
11206 motivated by the fact that memory allocation needs to be outside
11207 the critical section.
11209 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11211 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11212 with RESET_INTERVAL.
11214 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11215 Remove duplicated buffer name initialization.
11217 2012-05-02 Jim Meyering <jim@meyering.net>
11219 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11221 * xfns.c (x_window): Use xstrdup (Bug#11375).
11223 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11225 * xdisp.c (pos_visible_p): If already at a newline from the
11226 display string before the 'while' loop, don't walk back the glyphs
11227 from it3.glyph_row. Solves assertion violation when the display
11228 string begins with a newline (egg.el). (Bug#11367)
11230 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11232 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11235 2012-05-01 Glenn Morris <rgm@gnu.org>
11237 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11238 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11239 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11240 All were removed before 23.1.
11242 * dispnew.c: Remove HAVE_LIBNCURSES test;
11243 it is always true on relevant platforms.
11245 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11246 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11248 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11250 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11252 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11253 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11256 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11258 Do not avoid creating empty evaporating overlays (Bug#9642).
11259 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11260 That is, do not delete an evaporating overlay if it becomes
11261 empty after its bounds are adjusted to fit within its buffer.
11262 This fix caused other problems, and I'm reverting it until we get
11263 to the bottom of them.
11265 2012-04-27 Chong Yidong <cyd@gnu.org>
11267 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11269 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11271 * xdisp.c (pos_visible_p): If the window start position is beyond
11272 ZV, start the display from buffer beginning. Prevents assertion
11273 violation in init_iterator when the minibuffer window is scrolled
11274 via the scroll bar.
11276 * window.c (window_scroll_pixel_based): Likewise.
11278 2012-04-27 Chong Yidong <cyd@gnu.org>
11280 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11282 2012-04-27 Glenn Morris <rgm@gnu.org>
11284 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11285 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11287 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11289 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11290 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11292 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11294 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11295 display element, check also the underlying string or buffer
11296 character. (Bug#11341)
11298 * w32menu.c: Include w32heap.h.
11299 (add_menu_item): If the call to AppendMenuW (via
11300 unicode_append_menu) fails, disable Unicode menus only if we are
11301 running on Windows 9X/Me.
11303 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11305 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11306 (xgetint): Add missing shift for LSB tags.
11308 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11310 * keyboard.c (read_char): Don't wipe echo area for select window
11311 events: These might get delayed via `mouse-autoselect-window'
11314 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11316 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11317 manipulation of :loaded-from data.
11319 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11321 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11322 now a cons (bug#11311).
11324 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11326 Do not create empty overlays with the evaporate property (Bug#9642).
11327 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11328 if it becomes empty after its bounds are adjusted to fit within
11329 its buffer. Without this fix, in a nonempty buffer (let ((o
11330 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11331 yields an empty overlay that has the evaporate property, which is
11332 not supposed to happen.
11334 Fix minor GTK3 problems found by static checking.
11335 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11336 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11337 (struct _EmacsFixedClass, emacs_fixed_get_type):

11340 (emacs_fixed_class_init): Omit unused local.
11341 (emacs_fixed_child_type): Remove; unused.

11343 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11344 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11345 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11346 (EMACS_FIXED_GET_CLASS): Remove; unused.
11347 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11349 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11350 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11352 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11354 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11355 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11356 (__malloc_size_t, __malloc_ptrdiff_t):
11357 Remove. All uses removed, replaced by the definiens if needed,
11358 since we can assume C89 or better now.
11359 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
11360 (protect_malloc_state, align, get_contiguous_space)

11366 (special_realloc, _realloc_internal_nolock, _realloc_internal)
11367 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11368 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11369 Define using prototypes, not old style.
11370 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11371 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

11376 Omit no-longer-needed casts.
11377 (valloc): Use getpagesize, not __getpagesize.
11378 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11379 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11381 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11383 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

11434 * alloc.c: Handle unusual debugging option combinations.
11435 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
11436 since the two debugging options are incompatible.
11437 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
11439 (mem_init, mem_insert, mem_insert_fixup):
11440 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

11450 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11451 Use Emacs indenting style more consistently. Avoid some casts.
11452 Use 'double' consistently rather than mixing 'float' and 'double'.
11454 2012-04-21 Eduard Wiebe <usenet@pusto.de>
11456 * sysdep.c (list_system_processes, system_process_attributes):

11491 row, return zero immediately.
11492 (try_cursor_movement): If inside continuation line, don't back up
11493 farther than the first row after the header line, if any.
11494 Don't consider the header-line row as "partially visible", even if
11495 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

11533 New extern decls, to avoid calling undeclared functions.
11534 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11535 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11536 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11537 (NEED_MEM_INSERT): New macro.
11538 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11539 Remove one incorrect comment and fix another.

11553 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
11554 Remove decls. This fixes an "It stinks!".
11556 * alloc.c (which_symbols): Fix alignment issue / type clash.
11558 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11560 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11561 (struct Lisp_Misc_Any): Likewise.
11562 (struct Lisp_Free): Likewise.
11563 * alloc.c (union aligned_Lisp_Symbol): Define.

11571 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
11573 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
11574 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
11575 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11576 * s/netbsd.h, s/sol2-6.h:
11577 Remove definition of GC_MARK_STACK, since the default now works.
11578 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11579 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11580 no longer the default.
11581 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11583 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11585 * lread.c (lisp_file_lexically_bound_p):
11586 Fix hang at ";-*-\n" (bug#11238).
11588 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11590 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

11602 2012-04-13 Reuben Thomas <rrt@sc3d.org>
11604 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11606 2012-04-11 Daniel Colascione <dancol@dancol.org>
11608 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11609 against is gone. It's better to use vfork now so that when Cygwin
11610 gains a new, working vfork, we use it automatically (bug#10398).
11612 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11630 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
11632 * w32.c (w32_delayed_load): Record the full path of the library
11633 being loaded (bug#10424).
11635 2012-04-09 Glenn Morris <rgm@gnu.org>
11637 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11638 not just in the obarray, before snarfing them. (Bug#11036)
11640 * Makefile.in ($(leimdir)/leim-list.el):
11641 Pass EMACS rather than BUILT_EMACS.
11643 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
11645 * process.c (make_process):
11646 * process.h: Add integer `gnutls_handshakes_tried' member to

11655 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11656 attempts per process (connection).
11658 2012-04-09 Chong Yidong <cyd@gnu.org>
11660 * eval.c (Fuser_variable_p, user_variable_p_eh)
11661 (lisp_indirect_variable): Functions deleted.
11662 (Fdefvar): Caller changed.
11664 * callint.c (Finteractive, Fcall_interactively):
11665 * minibuf.c (Fread_variable): Callers changed.
11667 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11669 * xdisp.c (set_cursor_from_row): If the display string appears in
11670 the buffer at position that is closer to point than the position
11671 after the display string, display the cursor on the first glyph of
11672 the display string. Fixes cursor display when a 'display' text
11673 property immediately follows invisible text. (Bug#11094)
11675 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11677 composite.c: use 'double' consistently
11678 * composite.c (get_composition_id): Use 'double' consistently
11679 instead of converting 'float' to 'double' and vice versa; this is
11680 easier to understand and avoids a GCC warning.
11682 2012-04-09 Glenn Morris <rgm@gnu.org>
11684 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11685 preparation for dumping it with emacs. (Bug#4789)
11686 (leimdir): New variable.

11707 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11708 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11709 objects, as mark_maybe_pointer will catch them otherwise.
11710 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11711 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

11720 Support building on MS-Windows with libxml2.
11722 * makefile.w32-in (OBJ2): Add xml.$(O).
11723 (GLOBAL_SOURCES): Add xml.c.
11724 ($(BLD)/xml.$(O)): New dependency list.
11726 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11727 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11728 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11729 [!WINDOWSNT]: New macros.
11730 (init_libxml2_functions, libxml2_loaded_p): New functions.
11731 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11732 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11733 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11734 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11736 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11737 Call init_libxml2_functions before calling libxml2 functions.
11738 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11740 * emacs.c: Don't include libxml/parser.h.
11741 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11742 xmlCleanupParser directly.
11744 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11746 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11748 * indent.c (Fvertical_motion): If there is a display string at
11749 point, use it.vpos to compute how many lines to backtrack after
11750 move_it_to point. (Bug#11133)
11752 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11754 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11755 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11756 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11757 macros related to unification of CJK characters. For the details,
11758 see the discussion following the message here:
11759 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11761 2012-04-04 Chong Yidong <cyd@gnu.org>
11763 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11765 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11767 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

11775 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11777 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11778 position we get to after a call to move_it_to fails the
11779 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11780 only if we wind up in a string from display property. (Bug#11063)
11782 * window.c (Fdelete_other_windows_internal): Invalidate the row
11783 and column information about mouse highlight, so that redisplay
11784 restores it after reallocating the glyph matrices. (Bug#7464)
11786 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11787 string comes from a `display' text property, use the buffer
11788 position of that property as if we actually saw that position in
11790 (move_it_by_lines): Remove the assertion that
11791 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11792 violated when there's a before-string at the beginning of a line.
11795 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11797 * xdisp.c (append_space_for_newline): If the default face was

11799 (extend_face_to_end_of_line): Use the remapped default face for
11800 extending the face to the end of the line.
11801 (display_line): Call extend_face_to_end_of_line when the default
11802 face was remapped. (Bug#11068)
11804 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11806 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11808 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

11824 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11825 (command_loop_1): Use it; inhibit selection update for

11832 2012-03-25 Kenichi Handa <handa@m17n.org>
11834 * dispextern.h (struct glyph): Change the bit length of
11835 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11837 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11839 * s/ms-w32.h (tzname): Include time.h before redirecting to

11848 !SYNC_INPUT. (Bug#11080)
11850 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11852 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11853 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11854 when fetching a multibyte character consumes more bytes than
11855 CHAR_BYTES returns, due to unification of CJK characters in
11856 string_char. (Bug#11073)
11858 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11860 * process.c (wait_reading_process_output): Handle pty disconnect
11861 by refraining from sending oneself a SIGCHLD (bug#10933).

11892 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11894 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11895 that is not from display property, accept the row as a "cursor
11896 row" if one of the string's character has a non-nil `cursor'
11897 property. Fixes cursor positioning when there are newlines in
11898 overlay strings, e.g. in icomplete.el. (Bug#11035)
11900 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11902 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11904 2012-03-12 Chong Yidong <cyd@gnu.org>
11906 * eval.c (inhibit_lisp_code): Rename from
11907 inhibit_window_configuration_change_hook; move from window.c.
11909 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11910 * window.c (run_window_configuration_change_hook)
11911 (syms_of_window): Callers changed.
11913 2012-03-11 Chong Yidong <cyd@gnu.org>

11926 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11928 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11930 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11931 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11934 2012-03-03 Glenn Morris <rgm@gnu.org>
11936 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11938 2012-03-02 Eli Zaretskii <eliz@gnu.org>

11941 position past the first glyph_row that ends at ZV. (Bug#10902)
11942 (redisplay_window, next_element_from_string): Fix typos in
11944 (redisplay_window): Pass to move_it_vertically the margin in
11945 pixels, not in screen lines.
11947 2012-03-02 Glenn Morris <rgm@gnu.org>
11949 * buffer.c (buffer-list-update-hook): Doc fix.
11951 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11953 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11954 push_it before setting up the iterator for the first overlay
11955 string, even if we have an empty string loaded.
11956 (next_overlay_string): If there's an empty string on the iterator
11957 stack, pop the stack. (Bug#10903)
11959 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11961 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11962 Suggested by Stefan Monnier in
11963 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11964 * alloc.c (widen_to_Lisp_Object): New static function.
11965 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11966 and widening them to Lisp_Objects. This would work even if
11967 USE_LSB_TAG is defined and wide integers are used, which might
11968 happen in a future version of Emacs.
11970 2012-02-25 Chong Yidong <cyd@gnu.org>
11972 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11975 * xselect.c (Fx_selection_exists_p): Doc fix.

12012 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12013 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12014 It's useless in that case, and it can cause problems on hosts
12015 that allocate halves of EMACS_INT values separately.
12016 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12017 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12018 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12019 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12020 it avoids undefined behavior on hosts where shifting right by more
12021 than the word width has undefined behavior.
12023 2012-02-19 Chong Yidong <cyd@gnu.org>
12025 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12026 (Funhandled_file_name_directory, Ffile_name_as_directory)

12068 * window.c (Fdelete_window_internal): Invalidate the mouse
12069 highlight (Bug#9904).

12147 * character.c (char_width): Return EMACS_INT, not int.
12148 (char_width, c_string_width): Check for overflow when

12182 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12183 first 2 arguments are identical. This makes inserting large

12638 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12639 verifies glyph row's hash code--we have just reallocated the

12805 is set, removing the need for VIRT_ADDRESS_VARIES.
12806 (PURE_P): Use a more-efficient implementation that needs just one

12823 behave as if the cursor position were at the window margin.
12825 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12826 and the cursor position is out of bounds, behave as if the cursor
12827 position were at the window margin. (Bug#10075)
12829 2011-11-18 Chong Yidong <cyd@gnu.org>
12831 * window.c (Fwindow_combination_limit): Make first argument

12853 compute_line_metrics.
12854 (compute_line_metrics): Call row_hash, instead of computing the
12857 * dispnew.c (verify_row_hash): Call row_hash for computing the
12858 hash code of a row, instead of duplicating code from xdisp.c.
12860 * dispextern.h (row_hash): Add prototype.
12862 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
12864 * frame.c (delete_frame): Don't delete the terminal when the last

12913 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12914 with user-defined heap size. Bump the default size of the temacs

12918 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12919 current_matrix and desired_matrix. (Bug#9990)
12920 (verify_row_hash) [XASSERTS]: New function.

12965 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
12967 Avoid some portability problems by eschewing 'extern inline' functions.
12968 The trivial performance wins aren't worth the portability hassles; see
12969 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12971 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

13020 This is also needed for porting to any host where GC_MARK_STACK is
13021 not GC_MAKE_GCPROS_NOOPS.
13022 (which_symbols): Use it.

13037 * xmenu.c (cleanup_widget_value_tree): New function.
13038 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
13039 calling free_menubar_widget_value_tree directly (Bug#9830).
13041 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>

13045 (window_box_width, window_box_left, window_box_left_offset)
13046 (window_box_right, window_box_right_offset): Declare extern.
13047 Otherwise, these inline functions do not conform to C99 and
13048 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13049 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13050 * intervals.c (adjust_intervals_for_insertion)

13053 (static_offset_intervals): Remove.
13054 (offset_intervals): Rewrite using the old contents of
13055 static_offset_intervals. The old version didn't conform to C99
13056 because an extern inline function contained a reference to an
13057 identifier with static linkage.

13079 (Fwindow_vscroll): Doc fix.

13081 argument, since it makes no sense to pass a live window and for
13082 consistency with window-child.

13123 official. Move initialization of image_cache_refcount and
13124 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

13292 (w32font_open_internal, compute_metrics):
13293 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13294 instead of calling the "wide" APIs directly.

13369 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13370 * editfns.c: Rewrite current-time-zone so that it invokes
13371 the equivalent of (format-time-string "%Z") to get the time zone name.
13372 This fixes a bug when the time zone name contains characters that
13373 need converting from the system time locale to Emacs internal format.
13374 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13375 that patch fixed format-time-string to do the conversion, but
13376 I forgot to fix current-time-zone.
13377 (format_time_string): New function, containing most of
13378 what Fformat_time_string used to contain.
13379 (Fformat_time_string): Rewrite in terms of format_time_string.
13380 This doesn't change this function's behavior.
13381 (current-time-zone): Rewrite to use format_time_string.
13382 This fixes the bug reported by Michael Schierl in
13383 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13384 Jason Rumney's 2007-06-07 change worked around this bug, but
13386 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13388 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13390 * xdisp.c (start_display): If the character at POS is displayed
13391 via a display vector, reset IT->current.dpvec_index to zero.
13392 (try_window_reusing_current_matrix): If a line ends in a display
13393 vector or the next line starts in a display vector, continue
13394 redrawing the window even though the character position of
13395 start_row was reached.
13398 2011-10-18 Chong Yidong <cyd@gnu.org>
13400 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13401 with nobreak-char-display too.
13403 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13405 Fix part 3 of bug#9771.
13406 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13407 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13408 non-neutral characters if the current character is a paragraph
13409 separator (a.k.a. Newline). This avoids running the same
13410 expensive loop twice, once when we consume the preceding newline
13411 and the other time when the line actually needs to be displayed.
13412 Avoid the loop when we see neutrals on the base embedding level
13413 following a character whose directionality is the same as the
13414 paragraph's. This avoids running the expensive loop when a line
13415 ends in a long sequence of neutrals, like control characters.
13416 Add assertion against STRONG_AL type. Slightly rearrange code
13417 that determines the type of a neutral given the first non-neutral
13419 (bidi_level_of_next_char): Set next_en_pos to zero when
13420 invalidating its info.
13422 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13424 * xdisp.c (push_display_prop): Determine whether to record string
13425 or buffer position by IT->string, not by IT->method. Allow
13426 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13427 (move_it_vertically_backward): Don't look for character position
13428 immediately after the newline when in a continuation line.
13431 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13433 * window.c (coordinates_in_window): Rewrite and delabelize
13434 vertical border check. (Bug#5357) (Bug#9618)
13436 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13438 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13439 errors in XSetWindowBorder (bug#9310).
13441 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13443 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13444 avoid crash when xmalloc overrun checking is enabled.
13446 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13448 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13449 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13450 cursor motion with <left> and <right> arrow keys.
13452 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13453 some callers set that themselves.
13455 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13457 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13458 display string and the previous row comes from the same string and
13459 is empty. (Bug#9739) (Bug#9738)
13461 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13463 * doc.c (get_doc_string): Encode file name (bug#9735).
13465 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13467 * bidi.c (bidi_level_of_next_char):
13468 * xdisp.c (get_visually_first_element): Remove old incorrect
13469 comments regarding the Unicode Line Separator character.
13471 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13473 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13475 * alloc.c (Fgc_status): Do not access beyond zombies array
13476 boundary if nzombies > MAX_ZOMBIES.
13477 * alloc.c (dump_zombies): Add missing format specifier.
13479 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13481 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13482 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13484 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13485 Some packages use them to denote characters with modifiers.
13487 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13489 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13490 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13491 matching a pp-number. Rename parameter var to var1.
13493 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13495 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13497 2011-10-08 Glenn Morris <rgm@gnu.org>
13499 * callint.c (Fcall_interactively): Give a more explicit error for the
13500 'c' case with a non-character input. (Bug#8479)
13502 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13504 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13506 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13507 lines that are hscrolled on the left.
13509 * dispnew.c (buffer_posn_from_coords): Account for a possible
13510 presence of header-line. (Bug#4426)
13512 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13514 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13515 Don't advertise functionality which we discourage or doesn't work.
13517 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13519 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13520 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13521 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13522 this makes Emacs dump core during garbage collection on rare
13523 occasions. sizeof is obviously inferior to offsetof here, so
13524 stick with offsetof.
13525 (GC_POINTER_ALIGNMENT): New macro.
13526 (mark_memory): Omit 3rd (offset) arg; caller changed.
13527 Don't assume EMACS_INT alignment is the same as pointer alignment.
13529 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13531 * keyboard.c (read_key_sequence_remapped): New var.
13532 (read_key_sequence): Compute remapping in the right buffer.
13533 (command_loop_1): Use read_key_sequence's remapping directly.
13535 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13537 * dired.c (file_name_completion): Don't expand file name.
13538 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13539 before checking file name handler.
13541 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13542 they've been requested explicitly (bug#9591).
13544 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13546 * keymap.c (Fsingle_key_description): Use make_specified_string
13547 instead of build_string to build string from push_key_description.
13550 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13552 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13553 This fixes a Y2038 bug on 64-bit hosts.
13554 * buffer.c (reset_buffer):
13555 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13556 (Fclear_buffer_auto_save_failure):
13557 Use 0, not -1, to represent an unset failure time, since time_t
13558 might not be signed.
13560 Remove dependency on glibc malloc internals.
13561 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13562 Move back here from lisp.h, but with their new implementations.
13563 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13564 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13565 * charset.c (charset_table_init): New static var.
13566 (syms_of_charset): Use it instead of xmalloc. This removes a
13567 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13568 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13569 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13570 Move back to alloc.c.
13571 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13572 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13574 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13576 * nsterm.m (windowDidResize): Call x_set_window_size only when
13577 ns_in_resize is true. Otherwise set pixelwidth/height and
13578 call change_frame_size (Bug#9628).
13580 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13582 Port --enable-checking=all to Fedora 14 x86-64.
13583 * charset.c (syms_of_charset): Also account for glibc malloc's
13584 internal overhead when calculating the initial malloc maximum.
13586 Port --enable-checking=all to Fedora 14 x86.
13587 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13589 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13590 (overrun_check_realloc, overrun_check_free):
13591 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13592 That way, xmalloc returns a properly-aligned pointer even if
13593 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13594 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13595 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13596 into account when calculating the initial malloc maximum.
13597 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13598 Move here from alloc.c, so that charset.c can use it too.
13599 Properly align; the old code wasn't right for common 32-bit hosts
13600 when configured with --enable-checking=all.
13601 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13602 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13604 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13606 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13609 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13611 * xdisp.c (compute_display_string_end): If there's no display
13612 string at CHARPOS, return -1.
13614 * bidi.c (bidi_fetch_char): When compute_display_string_end
13615 returns a negative value, treat the character as a normal
13616 character not covered by a display string. (Bug#9624)
13618 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13620 * lread.c (Fread_from_string): Fix typo in docstring.
13622 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13624 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13625 newline, reseat the iterator instead of bidi-iterating there one
13626 character at a time. (Bug#9610)
13627 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13628 TO_CHARPOS if the bidi iterator is at base embedding level.
13630 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13632 * lread.c (readevalloop): Use correct code for NBSP.
13633 (read1): Likewise. (Bug#9608)
13635 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13637 * dbusbind.c (Fdbus_register_signal): When service is not
13638 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13640 2011-09-25 Glenn Morris <rgm@gnu.org>
13642 * buffer.c (truncate-lines): Doc fix.
13644 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13646 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13647 (Fset_window_next_buffers): Doc fix.
13649 2011-09-24 Glenn Morris <rgm@gnu.org>
13651 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13653 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13655 Fix minor problems found by static checking.
13656 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13657 * indent.c (Fvertical_motion): Fix == vs = typo.
13659 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13661 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13662 Default value is now t. Doc fix.
13664 * indent.c (Fvertical_motion): Compute and apply the overshoot
13665 logic when moving up, not only when moving down. Fix the
13666 confusing name and values of the it_overshoot_expected variable;
13667 logic changes accordingly. (Bug#9254) (Bug#9549)
13669 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13670 CHARPOS is covered by a display string which includes newlines.
13671 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13672 is covered by a display string with embedded newlines.
13674 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13676 * dbusbind.c (Fdbus_register_signal): Add match rule to
13677 Vdbus_registered_objects_table. (Bug#9581)
13678 (Fdbus_register_method, Vdbus_registered_objects_table):
13681 2011-09-24 Jim Meyering <meyering@redhat.com>
13683 do not ignore write error for any output size
13684 The previous change was incomplete.
13685 While it makes emacs --batch detect the vast majority of stdout
13686 write failures, errors were still ignored whenever the output size is
13687 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13688 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13689 && echo FAIL: ignored write error
13690 FAIL: ignored write error
13691 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13692 && echo FAIL: ignored write error
13693 FAIL: ignored write error
13694 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13696 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13698 * emacs.c (Fkill_emacs): In noninteractive mode exit
13699 non-successfully if a write error occurred on stdout. (Bug#9574)
13701 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13703 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13706 * dispextern.h (struct it): Update the comment documenting what
13709 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13711 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13712 a display string, extend search for cursor position to end of row.
13713 (find_row_edges): If the row ends in a newline from a display
13714 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13715 Handle the case of a display string with multiple newlines.
13716 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13717 non-empty line. Fixes confusing cursor motion with arrow keys at
13718 the beginning of a line that starts with whitespace.
13720 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13722 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13725 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13727 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13728 boolean (Bug#9154).
13730 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13732 * xdisp.c (display_line): Record maximum and minimum buffer
13733 positions even if no glyphs were produced (e.g., by a zero-width
13734 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13735 buffer positions that will be removed from the glyph row because
13737 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13738 column is beyond frame width: don't subtract 1 "pixel" when
13739 computing width of the stretch.
13740 (reseat_at_next_visible_line_start): Undo the change made on
13741 2011-09-17 that saved paragraph information and restored it after
13742 the call to `reseat'. (Bug#9545)
13744 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13746 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13747 and turn window cursor on if cleared (Bug#9415).
13749 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13751 * search.c (boyer_moore): Take unibyte characters from pattern
13752 literally. (Bug#9458)
13754 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13756 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13758 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13760 Fix minor problem found by static checking.
13761 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13762 initialized, to pacify gcc -Wuninitialized.
13764 * fileio.c: Report proper errno when syscall falls.
13765 (Finsert_file_contents): Save and restore errno,
13766 so that report_file_error outputs the correct diagnostic.
13767 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13769 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13771 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13773 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13775 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13776 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13778 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13780 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13781 about the current paragraph and restore it after the call to reseat.
13783 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13784 (bidi_find_paragraph_start): Search back for paragraph beginning
13785 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13786 (bidi_move_to_visually_next): Only trigger paragraph-related
13787 computations when the last character is a newline or at EOB, not
13788 just any NEUTRAL_B. (Bug#9470)
13790 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13791 truncated lines if point is covered by a display string. (Bug#9524)
13793 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13795 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13796 (cons_to_x_long): New function.
13797 (lisp_data_to_selection_data): Use it. Correct the test for
13798 short-versus-long data; it was negated. Break out of vector
13799 loop, for efficiency, when a long datum is discovered.
13801 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13803 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13805 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13807 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13808 GCC PR/17406) by declaring this function with external scope.
13810 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13812 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

13817 * editfns.c (Fformat): Correctly handle text properties on "%%".
13819 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13821 * xterm.c (x_draw_composite_glyph_string_foreground):
13822 * w32term.c (x_draw_composite_glyph_string_foreground):
13823 * term.c (encode_terminal_code):
13824 * composite.c (composition_update_it, get_composition_id):
13825 * xdisp.c (get_next_display_element)
13826 (fill_composite_glyph_string): Add comments about special meaning
13827 of TAB characters in a composition.
13829 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13831 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13832 This occurs when processing a multibyte format.
13833 Problem reported by Wolfgang Jenker.
13835 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13837 * xdisp.c (try_cursor_movement): Only check for exact match if
13838 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13840 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13842 Remove unused external symbols.
13843 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13844 * xdisp.c (calc_pixel_width_or_height): Now static.
13845 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13846 * indent.c (check_display_width):
13847 * w32term.c: Fix comment to match code.
13848 * xterm.c, xterm.h (x_catching_errors): Remove.
13850 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13852 * xselect.c: Use signed conversions more consistently (Bug#9498).
13853 (selection_data_to_lisp_data): Assume incoming selection data are
13854 signed integers, not unsigned. This is to be consistent with
13855 outgoing selection data, which was modified to use signed integers
13856 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13857 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13858 expects long, not unsigned long.
13860 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13862 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13863 computation of loop end. Reported by Johan Bockgård
13866 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13868 * frame.c (Fother_visible_frames_p): Function deleted.
13870 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13872 * indent.c (compute_motion): Process display vector front to back
13873 rather than the other way around. (Bug#2496)
13875 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13877 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13879 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13881 * minibuf.c (Fread_from_minibuffer): Doc fix.
13883 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13885 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13886 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13888 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13890 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13891 value for non-existent files.
13893 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13895 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13896 set its "size" to -1. This will set the modtime_size field of
13897 the corresponding buffer to -1, which is what
13898 verify-visited-file-modtime expects for files that do not exist.
13901 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13903 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13905 * lisp.h: ... from here. push_key_description is no longer
13906 defined in keyboard.c, so its declaration should not be in
13907 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13908 logically belongs with push_key_description.
13910 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13912 * buffer.h: Include <sys/types.h> instead of <time.h>.
13913 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13914 Problem reported by Herbert J. Skuhra.
13916 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13918 * xml.c (parse_region): Make the parsing work for
13919 non-comment-starting XML files again (bug#9144).
13921 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13923 * image.c (gif_load): Fix calculation of bottom and right corner.
13926 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13928 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13929 redisplay in small windows.
13931 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13933 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13935 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13937 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13938 Operate on live windows only.
13940 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13942 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13944 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13946 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13947 only under bidi iteration.
13949 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13951 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13953 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13955 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13956 Without this fix, the command to link temacs failed due to an
13957 undefined symbol __builtin_isnan. This is because
13958 /usr/include/iso/math_c99.h #defines isnan(x) to
13959 __builtin_isnan(x), but the bundled gcc, which identifies itself
13960 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13962 * floatfns.c (isnan): #undef, and then #define to a clone of
13964 (Fisnan): Always define, since it's always available now.
13965 (syms_of_floatfns): Always define isnan at the Lisp level.
13967 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13969 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13971 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13973 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13974 The previous code assumed that file offsets (off_t values) fit in
13975 EMACS_INT variables, which is not true on typical 32-bit hosts.
13976 The code messed up by falsely reporting buffer overflow in cases
13977 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13978 when "big" contains more than 2**29 bytes, even though this
13979 inserts just one byte and does not overflow the buffer.
13980 (Finsert_file_contents): Store file offsets as off_t
13981 values, not as EMACS_INT values. Check for overflow when
13982 converting between EMACS_INT and off_t. When checking for
13983 buffer overflow or for overlap, take the offsets into account.
13984 Don't use EMACS_INT for small values where int suffices.
13985 When checking for overlap, fix a typo: ZV was used where
13986 ZV_BYTE was intended.
13987 (Fwrite_region): Don't assume off_t fits into 'long'.
13988 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13990 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13992 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13994 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13996 sprintf-related integer and memory overflow issues (Bug#9412).
13998 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13999 (esprintf, exprintf, evxprintf): New functions.
14000 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14001 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14002 (modify_event_symbol): Do not assume that the length of
14003 name_alist_or_stem is safe to alloca and fits in int.
14004 (Fexecute_extended_command): Likewise for function name and binding.
14005 (Frecursion_depth): Wrap around reliably on integer overflow.
14006 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14007 since some callers pass EMACS_INT values.
14008 (Fsingle_key_description): Don't crash if symbol name contains more
14009 than MAX_ALLOCA bytes.
14010 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14011 (get_minibuffer): Arg is now EMACS_INT, not int.
14012 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14013 (esprintf, exprintf, evxprintf): New decls.
14014 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14016 * dbusbind.c (signature_cat): New function.
14017 (xd_signature, Fdbus_register_signal):
14018 Do not overrun buffer; instead, report string overflow.
14020 * dispnew.c (add_window_display_history): Don't overrun buffer.
14021 Truncate instead; this is OK since it's just a log.
14023 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14024 even if the time zone offset is outlandishly large.
14025 Don't mishandle offset == INT_MIN.
14027 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14028 when creating daemon; the previous buffer-overflow check was incorrect.
14030 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14031 which has the guts of the old verror function.
14033 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14034 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14036 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14037 (font_unparse_xlfd): Don't blindly alloca long strings.
14038 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14039 fits in int, when using sprintf. Use single snprintf to count
14040 length of string rather than counting it via multiple sprintfs;
14041 that's simpler and more reliable.
14042 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14043 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14044 sprintf, in case result does not fit in int.
14046 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14047 (fontset_from_font): Print it.
14049 * frame.c (tty_frame_count): Now printmax_t, not int.
14050 (make_terminal_frame, set_term_frame_name): Print it.
14051 (x_report_frame_params): In X, window IDs are unsigned long,
14052 not signed long, so print them as unsigned.
14053 (validate_x_resource_name): Check for implausibly long names,
14054 and don't assume name length fits in 'int'.
14055 (x_get_resource_string): Don't blindly alloca invocation name;
14056 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14059 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14060 (xg_check_special_colors, xg_set_geometry):
14061 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14063 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14064 Use esprintf, not sprintf, in case result does not fit in int.
14066 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14067 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14068 it as a large positive number.
14069 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14070 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14072 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14073 in case result does not fit in int.
14075 * print.c (float_to_string): Detect width overflow more reliably.
14076 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14077 buffer overrun. Don't assume list length fits in 'int'. Treat
14078 print length of 0 as 0, not as infinity; to be consistent with other
14079 uses of print length in this function. Don't overflow print length
14080 index. Don't assume hash table size fits in 'long', or that
14081 vectorlike size fits in 'unsigned long'.
14083 * process.c (make_process): Use printmax_t, not int, to format
14084 process-name gensyms.
14086 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14088 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14089 to avoid potential buffer overrun.
14091 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14092 if X resource line is longer than 512 bytes.
14094 * xfns.c (x_window): Make sprintf buffer a bit bigger
14095 to avoid potential buffer overrun.
14097 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14099 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14101 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14103 Integer overflow fixes for scrolling, etc.
14104 Without these, Emacs silently mishandles large integers sometimes.
14105 For example, "C-u 4294967297 M-x recenter" was treated as if
14106 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14108 * xdisp.c (try_window_id): Check Emacs fixnum range before
14109 converting to 'int'.
14111 * window.c (window_scroll_line_based, Frecenter):
14112 Check that an Emacs fixnum is in range before assigning it to 'int'.
14113 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14114 values converted from Emacs fixnums.
14115 (Frecenter): Don't wrap around a line count if it is out of 'int'
14116 range; instead, treat it as an extreme value.
14117 (Fset_window_configuration, compare_window_configurations):
14118 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14120 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14121 that can exceed INT_MAX. Check that EMACS_INT value is in range
14122 before assigning it to the (possibly-narrower) index.
14123 (match_limit): Don't assume that a fixnum can fit in 'int'.
14125 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14128 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14129 (Fvertical_motion): Don't wrap around LINES values that don't fit
14130 in 'int'. Instead, treat them as extreme values. This is good
14131 enough for windows, which can't have more than INT_MAX lines anyway.
14133 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14135 * Require libxml/parser.h to avoid compilation warning.
14137 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14139 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14140 since this reportedly can destroy thread storage.
14142 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14144 * syntax.c (find_defun_start): Update all cache variables if
14145 exiting early (Bug#9401).
14147 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14149 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14151 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14152 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14153 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14155 * term.c (tty_append_glyph): New function.
14156 (produce_stretch_glyph): Static function and its prototype deleted.
14158 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14161 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14163 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14164 when checking :margin (Bug#9390).
14165 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14166 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14167 so that the name doesn't mislead. All uses changed.
14169 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14171 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14174 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14176 * xdisp.c (move_it_to): Don't bail out early when reaching
14177 position beyond to_charpos, if we are scanning backwards.
14178 (move_it_vertically_backward): When DY == 0, make sure we get to
14179 the first character in the line after the newline.
14181 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14183 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14184 (ccl_driver): Do not generate an out-of-range pointer.
14185 (Fccl_execute_on_string): Remove unnecessary check for
14186 integer overflow, noted by Stefan Monnier in
14187 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14188 Remove a FIXME that didn't need fixing.
14189 Simplify the newly-introduced buffer reallocation code.
14191 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14193 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14195 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14197 Integer and memory overflow issues (Bug#9196).
14199 * doc.c (get_doc_string): Rework so that
14200 get_doc_string_buffer_size is the actual buffer size, rather than
14201 being 1 less than the actual buffer size; this makes xpalloc more
14204 * image.c (x_allocate_bitmap_record, cache_image):
14205 * xselect.c (Fx_register_dnd_atom):
14206 Simplify previous changes by using xpalloc.
14208 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14209 since either will do and ptrdiff_t is convenient with xpalloc.
14211 * charset.c (charset_table_size)
14212 (struct charset_sort_data.priority): Now ptrdiff_t.
14213 (charset_compare): Don't overflow if priorities differ greatly.
14214 (Fsort_charsets): Don't assume list length fits in int.
14215 Check for size-calculation overflow when allocating sort data.
14216 (syms_of_charset): Allocate an initial charset table that is
14217 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14219 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14221 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14222 The actual value is always <= INT_MAX, and leaving it unsigned made
14223 overflow checking harder.
14225 * dispextern.h (struct glyph_matrix.rows_allocated)
14226 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14227 with xpalloc. The values are still always <= INT_MAX.
14229 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14231 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14232 (SAFE_NALLOCA): New macro.
14234 * region-cache.c (struct boundary.pos, find_cache_boundary)
14235 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14236 (set_cache_region, invalidate_region_cache)
14237 (revalidate_region_cache, know_region_cache, region_cache_forward)
14238 (region_cache_backward, pp_cache):
14239 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14240 so that ptrdiff_t * can be passed to xpalloc.
14241 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14242 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14243 (pp_cache): Don't assume cache_len fits in int.
14244 * region-cache.h: Adjust extern decls to match.
14246 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14247 EMACS_INT, since either will do, for xpalloc.
14249 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14250 (xnmalloc, xnrealloc, xpalloc): New functions.
14252 * bidi.c (bidi_shelve_header_size): New constant.
14253 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14254 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14256 * bidi.c (bidi_cache_shrink):
14257 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14259 Don't update size of array until after memory allocation succeeds,
14260 because xmalloc/xrealloc may not return.
14261 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14262 now that we have proper integer overflow checking.
14263 (record_overlay_string, overlay_strings): Catch overflows when
14264 calculating size of overlay_str_buf.
14266 * callproc.c (Fcall_process): Check for size overflow when
14267 calculating size of args2.
14268 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14269 Normally we prefer signed values, but sticking with ptrdiff_t would
14270 require adding more-complicated checks.
14272 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14273 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14274 Redo buffer-overflow calculations to avoid integer overflow.
14275 Add a FIXME comment where memory seems to be over-allocated.
14277 * character.c (Fstring): Check for size-calculation overflow.
14279 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14280 unnecessary integer overflow. Check for size overflow.
14281 (encode_coding_object): Don't update size until xmalloc succeeds.
14283 * composite.c (get_composition_id): Check for overflow in glyph
14284 length calculations.
14286 Integer and memory overflow fixes for display code.
14287 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14288 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14289 (scrolling_window): Check for overflow in size calculations.
14290 (line_draw_cost, realloc_glyph_pool, add_row_entry):
14291 Don't assume glyph table len fits in int.
14292 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
14293 (row_table_size): Now ptrdiff_t, not int.
14294 (scrolling_window): Avoid overflow in size calculations.
14295 Don't update size until allocation succeeds.
14296 * fns.c (concat): Check for overflow in size calculations.
14297 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.

14313 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14315 * emacs.c (main): Do not reallocate argv, since there is a null at
14316 the end that can be overwritten, and this way there's no need to
14317 worry about size-calculation overflow.
14318 (sort_args): Check for size-calculation overflow.

14341 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14342 do, as we prefer signed integers.

14447 (X_LONG_MIN): New macros.
14448 Use them to make the following changes clearer.
14449 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

14451 future maintainers not to raise the value too much later.
14452 (SELECTION_QUANTUM): Remove, replacing with ...
14453 (selection_quantum): ... new function, which avoids overflow.
14455 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14456 assumption that selection length fits in 'int'.

14473 Don't store size until memory allocation succeeds.
14474 (x_get_window_property): Plug memory leak on memory exhaustion.
14475 Don't double-block input; malloc is safe here. Don't assume 2**34
14476 - 4 fits in unsigned long. Add an xassert to check
14477 XGetWindowProperty overflow. Be more careful about overflow
14478 calculations, and distinguish size from memory overflow better.
14479 (receive_incremental_selection): When tracing, don't assume
14480 unsigned int is less than INT_MAX.
14481 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

14484 in the range -65535 through -1 fit in an X unsigned short.
14485 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14486 result parameters unless successful. Rely on cons_to_unsigned
14487 to report problems with elements; the old code wasn't right anyway.

14522 * lisp.h (hash_lookup, hash_put):
14523 * minibuf.c (Ftest_completion):
14524 Use ptrdiff_t for hash table indexes, not int (which is too
14525 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14526 32-bit --with-wide-int hosts).
14528 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14529 Add a FIXME comment about memory leaks.

14567 Change bufsize argument back to int, undoing my 2011-03-30 change.
14568 We prefer signed types, and int is wide enough here.
14569 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14570 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14571 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14572 length, not size_t. Use ptrdiff_t for index, not int.
14573 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14574 possibility of integer overflow.

14602 Prefer int to unsigned where either will do.
14603 (tiff_handler): New function, combining the cores of the
14604 old tiff_error_handler and tiff_warning_handler.

14606 stack buffer overflows. It uses only the features of vsnprintf
14607 that are common to both POSIX and native Microsoft.
14608 (tiff_error_handler, tiff_warning_handler): Use it.
14609 (tiff_load, gif_load, imagemagick_load_image):
14610 Don't assume :index value fits in 'int'.
14611 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

14656 positioning on the newline at EOL of R2L text within L2R
14657 paragraph, and vice versa.
14658 (try_cursor_movement): Check continued rows, in addition to
14659 continuation rows. Fixes unwarranted scroll when point enters a
14660 continued line of R2L text within an L2R paragraph, or vice versa.
14661 (cursor_row_p): Consider the case of point being equal to
14662 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

14691 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14692 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14693 candidate is selected by the mouse, and that candidate has a
14694 composed character under the mouse.
14696 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14697 coordinates reported by pos-visible-in-window-p for a composed

14707 consider it a hit if to_charpos is anywhere in the range of the
14708 composed buffer positions.
14710 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14712 * image.c (gif_load): Don't assume that each subimage has the same
14713 dimensions as the base image. Handle disposal method that is
14714 "undefined" by the gif spec (Bug#9335).
14716 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14718 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14730 with a composed character.
14732 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14734 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14735 character bidirectional type, use STRONG_L instead. Fixes crashes
14736 in a buffer produced by `describe-categories'.
14738 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14739 members before the level stack, so they would be saved and
14740 restored when copying iterator state. Fixes incorrect reordering
14741 around TABs covered by display properties.
14743 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14745 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
14747 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
14749 * eval.c (internal_condition_case, internal_condition_case_1)
14750 (internal_condition_case_2, internal_condition_case_n):
14751 Remove unnecessary aborts (Bug#9081).
14753 2011-08-17 Eli Zaretskii <eliz@gnu.org>
14755 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
14756 has no `load' handler, try opening the file locally. (Bug#9311)
14758 2011-08-16 Ken Brown <kbrown@cornell.edu>
14760 * gmalloc.c: Expand comment.
14762 2011-08-16 Eli Zaretskii <eliz@gnu.org>
14764 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
14765 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
14767 2011-08-16 Ken Brown <kbrown@cornell.edu>
14769 Fix memory allocation problems in Cygwin build (Bug#9273).
14771 * unexcw.c ( __malloc_initialized): Declare external variable.

14776 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
14778 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
14779 in the static heap.
14780 [CYGWIN] (special_realloc): New function.
14781 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
14782 requests to realloc storage in the static heap.
14784 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
14786 * bidi.c (bidi_initialize): Remove unused local.

14793 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
14795 * dispextern.h: Fix a typo in the comment to bidi_type_t.
14797 * chartab.c: Improve commentary for the uniprop_table API.
14799 * bidi.c (bidi_paragraph_init): Support zero value of
14800 bidi_ignore_explicit_marks_for_paragraph_level.
14801 (bidi_initialize): Use uniprop_table instead of including
14802 biditype.h and bidimirror.h.
14804 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
14805 coordinates of the iterator when restoring from ppos_it.
14808 2011-08-14 Kenichi Handa <handa@m17n.org>
14810 * process.c (create_process): Call setup_process_coding_systems
14811 after the pid of the process is set to -1 (Bug#8162).
14813 2011-08-14 Eli Zaretskii <eliz@gnu.org>
14815 * xdisp.c (move_it_in_display_line_to): Don't invoke
14816 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14817 ppos_it. Fixes vertical cursor motion when line beginning is
14818 covered by an image. (Bug#9296)
14820 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14822 * nsterm.h (ns_run_ascript): Declare.
14823 (NSAPP_DATA2_RUNASSCRIPT): Define.
14825 * nsfns.m (as_script, as_result, as_status): New static variables.
14826 (ns_run_ascript): New function.
14827 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14828 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14829 the event loop. Get status from as_status (Bug#7276).
14831 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14832 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14833 the event loop (Bug#7276).
14835 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14837 * gnutls.c (QCgnutls_bootprop_priority)
14838 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
14839 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
14840 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
14841 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
14842 (QCgnutls_bootprop_verify_hostname_error)
14843 (QCgnutls_bootprop_callbacks_verify): Rename from
14844 Qgnutls_bootprop_..., all uses changed.
14846 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
14849 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
14851 * xfaces.c (Qframe_set_background_mode): Now static.

14856 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
14858 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
14859 (Fnetwork_interface_list): Allocate in increments of bytes instead
14860 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14861 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14863 (struct ifflag_def): notrailers is smart on OSX.
14864 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14865 Get hardware address with getifaddrs if available.
14867 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14869 * xdisp.c (iterate_out_of_display_property): xassert that
14870 IT->position is set to within IT->object's boundaries. Break from
14871 the loop as soon as EOB is reached; avoids infloops in redisplay
14872 when IT->position is set up wrongly due to some bug.
14873 Set IT->current to match the bidi iterator unconditionally.
14874 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14875 entry. Force push_it to save on the stack the current
14876 buffer/string position, to be restored by pop_it. Fix flags in
14877 the iterator structure wrt the object coming from a display
14878 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14879 properties. (Bug#9284)
14881 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14883 * fontset.c (fontset_get_font_group): Add proper type checks.
14886 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14888 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
14889 and LC_VERSION_MIN_MACOSX.
14890 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
14891 (dump_it) [LC_FUNCTION_STARTS]: Use it.
14893 2011-08-08 Eli Zaretskii <eliz@gnu.org>
14895 * xdisp.c (forward_to_next_line_start): Allow to use the
14896 no-display-properties-and-no-overlays under bidi display.
14897 Set disp_pos in the bidi iterator to avoid searches for display
14898 properties and overlays.
14900 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14902 * editfns.c (Fset_time_zone_rule): Document relationship with the
14905 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
14906 the font entity extracted from the cache (Bug#8109).
14908 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14910 * composite.c (autocmp_chars): Don't reset point. That is done by
14911 restore_point_unwind (Bug#5984).
14913 2011-08-07 Juri Linkov <juri@jurta.org>
14915 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14916 to show the arg `TIME' instead of `TIMEVAL'.
14918 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14920 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14921 display property strides EOL and includes a newline, as in
14922 longlines-mode. (Bug#9254)
14923 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14924 word-wrap under bidirectional display. (Bug#9224)
14926 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14927 is non-zero, even if the data buffer is NULL. Fixes a crash in
14928 vertical-motion with longlines-mode. (Bug#9254)
14930 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14932 * bidi.c <bidi_cache_total_alloc>: Now static.
14933 (bidi_initialize): Initialize bidi_cache_total_alloc.
14935 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14938 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14939 amount allocated this far in `bidi_cache_total_alloc'.
14940 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14941 non-zero, only free the data buffer without restoring the cache
14942 contents. All callers changed.
14944 * dispextern.h (bidi_unshelve_cache): Update prototype.
14946 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14947 (move_it_in_display_line, move_it_to)
14948 (move_it_vertically_backward, move_it_by_lines): Replace the call
14949 to xfree to an equivalent call to bidi_unshelve_cache.
14950 (move_it_in_display_line_to): Fix logic of returning
14951 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14953 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14955 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14956 came from a string character with a `cursor' property. (Bug#9229)
14958 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14960 * Makefile.in (LIB_PTHREAD): New variable.
14961 (LIBES): Add LIB_PTHREAD (Bug#9216).
14963 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14964 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14966 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14968 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14970 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14972 * xterm.c (x_find_topmost_parent): New function.
14973 (x_set_frame_alpha): Find topmost parent window with
14974 x_find_topmost_parent and set the property there also (bug#9181).
14975 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14977 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14979 * callproc.c (Fcall_process): Avoid vfork clobbering
14980 the local vars buffer, coding_systems, current_dir.
14982 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14984 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14986 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14988 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14989 so that it is not optimized away.
14991 * xdisp.c (compute_display_string_pos): Remove unused local.
14993 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14995 Fix slow cursor motion and scrolling in large buffers with
14996 selective display, like Org Mode buffers. (Bug#9218)
14998 * dispextern.h (struct bidi_it): New member disp_prop_p.
15000 * xdisp.c: Remove one-slot cache of display string positions.
15001 (compute_display_string_pos): Accept an additional argument
15002 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15003 for a display string or property. If found, set DISP_PROP_P
15006 * bidi.c (bidi_fetch_char): Accept an additional argument
15007 DISP_PROP_P, and pass it to compute_display_string_pos.
15008 Only handle text covered by a display string if DISP_PROP_P is returned
15009 non-zero. All callers of bidi_fetch_char changed.
15011 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15013 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15015 2010-12-03 Don March <don@ohspite.net>
15017 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15018 last character M-[char] is translated to ESC [char] (bug#7541).
15020 2011-08-02 Kenichi Handa <handa@m17n.org>
15022 * lisp.h (uniprop_table): Extern it.
15024 * chartab.c (uniprop_table): Make it non-static.
15026 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15028 * xdisp.c (forward_to_next_line_start): Accept additional argument
15029 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15031 (reseat_at_next_visible_line_start): Use the bidi iterator state
15032 returned by forward_to_next_line_start to restore the state of
15033 it->bidi_it after backing up to previous newline. (Bug#9212)
15035 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15037 * regex.c (re_comp): Protoize.
15038 (re_exec): Fix return type.
15039 (regexec): Fix type of `ret'. (Bug#9203)
15041 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15043 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15044 This is needed if max-image-size is a floating-point number.
15046 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15048 * print.c (print_object): Print empty symbol as ##.
15050 * lread.c (read1): Read ## as empty symbol.
15052 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15054 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15055 setting frame foreground color (Bug#9175).
15056 (x_set_background_color): Likewise.
15058 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15059 contents (Bug#9176).
15060 (EmacsTooltip -init): Remove bezels and add shadows to
15063 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15064 or scroll bar (Bug#8470).
15066 * nsfont.m (nsfont_open): Remove assignment to voffset and
15067 unnecessary vars hshink, expand, hd, full_height, min_height.
15068 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15070 * nsterm.h (nsfont_info): Remove voffset field.
15072 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15074 Implement strike-through and overline on NextStep (Bug#8863).
15076 * nsfont.m (nsfont_open): Use underline position provided by font,
15077 instead of hard-coded value of 2.
15078 (nsfont_draw): Call ns_draw_text_decoration instead.
15080 * nsterm.h: Add declaration for ns_draw_text_decoration.
15082 * nsterm.m (ns_draw_text_decoration): New function for drawing
15083 underline, overline, and strike-through.
15084 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15085 ns_draw_text_decoration. Change treatment of cursor drawing to
15086 accommodate underlining, etc.
15088 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15090 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15093 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15095 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15096 Without this fix, if a signal arrives just after memory fills up,
15097 'malloc' might be invoked reentrantly.
15099 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15100 In other words, assume that every image size is allowed, on non-X
15101 hosts. This assumption is probably wrong, but it lets Emacs compile.
15103 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15105 * regex.c (re_iswctype): Convert return values to boolean.
15107 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15109 * xdisp.c (compute_display_string_pos): Don't use cached display
15110 string position if the buffer had its restriction changed.
15113 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15115 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15117 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15119 Integer signedness and overflow and related fixes. (Bug#9079)
15121 * bidi.c: Integer size and overflow fixes.
15122 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15123 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15124 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15125 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15126 (bidi_find_other_level_edge):
15127 Use ptrdiff_t instead of EMACS_INT where either will do.
15128 This works better on 32-bit hosts configured --with-wide-int.
15129 (bidi_cache_ensure_space): Check for size-calculation overflow.
15130 Use % rather than repeated addition, for better worst-case speed.
15131 Don't set bidi_cache_size until after xrealloc returns, because it
15133 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15134 (bidi_cache_ensure_space): Also check that the bidi cache size
15135 does not exceed that of the largest Lisp string or buffer. See Eli
15136 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15138 * alloc.c (__malloc_size_t): Remove.
15139 All uses replaced by size_t. See Andreas Schwab's note
15140 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15142 * image.c: Improve checking for integer overflow.
15143 (check_image_size): Assume that f is nonnull, since
15144 it is always nonnull in practice. This is one less thing to
15145 worry about when checking for integer overflow later.
15146 (x_check_image_size): New function, which checks for integer
15147 overflow issues inside X.
15148 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15149 This removes the need for a memory_full check.
15150 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15151 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15152 (xbm_read_bitmap_data): Change locals back to 'int', since
15153 their values must fit in 'int'.
15154 (xpm_load_image, png_load, tiff_load):
15155 Invoke x_create_x_image_and_pixmap earlier,
15156 to avoid much needless work if the image is too large.
15157 (tiff_load): Treat overly large images as if
15158 x_create_x_image_and_pixmap failed, not as malloc failures.
15159 (gs_load): Use x_check_image_size.
15161 * gtkutil.c: Omit integer casts.
15162 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15163 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15165 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15167 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15168 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15169 would wrongly return t on a 64-bit host.
15171 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15172 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15173 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15174 and therefore cause GCC to emit a bogus diagnostic in some cases.
15176 * image.c: Integer signedness and overflow and related fixes.
15177 This is not an exhaustive set of fixes, but it's time to
15178 record what I've got.
15179 (lookup_pixel_color, check_image_size): Remove redundant decls.
15180 (check_image_size): Don't assume that arbitrary EMACS_INT values
15181 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15182 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15183 (tiff_load, imagemagick_load_image):
15184 Check for overflow in size calculations.
15185 (x_create_x_image_and_pixmap): Remove unnecessary test for
15186 xmalloc returning NULL; that can't happen.
15187 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15188 (xpm_color_bucket): Use better integer hashing function.
15189 (xpm_cache_color): Don't possibly over-allocate memory.
15190 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15191 (gif_memory_source):
15192 Use ptrdiff_t, not int or size_t, to record sizes.
15193 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15194 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15195 either works, as we prefer signed integers.
15196 (tiff_read_from_memory, tiff_write_from_memory):
15197 Return tsize_t, not size_t, since that's what the TIFF API wants.
15198 (tiff_read_from_memory): Don't fail simply because the read would
15199 go past EOF; instead, return a short read.
15200 (tiff_load): Omit no-longer-needed casts.
15201 (Fimagemagick_types): Don't assume size fits into 'int'.
15203 Improve hashing quality when configured --with-wide-int.
15204 * fns.c (hash_string): New function, taken from sxhash_string.
15205 Do not discard information about ASCII character case; this
15206 discarding is no longer needed.
15207 (sxhash-string): Use it. Change sig to match it. Caller changed.
15208 * lisp.h: Declare it.
15209 * lread.c (hash_string): Remove, since we now use fns.c's version.
15210 The fns.c version returns a wider integer if --with-wide-int is
15211 specified, so this should help the quality of the hashing a bit.
15213 * emacs.c: Integer overflow minor fix.
15214 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15215 Define only if GNU_LINUX.
15216 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15218 * dispnew.c: Integer signedness and overflow fixes.
15219 Remove unnecessary forward decls, that were a maintenance hassle.
15220 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15222 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15223 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15224 (prepare_desired_row, line_draw_cost):
15225 Use int, not unsigned, where either works.
15226 (save_current_matrix, restore_current_matrix):
15227 Use ptrdiff_t, not size_t, where either works.
15228 (init_display): Check for overflow more accurately, and without
15229 relying on undefined behavior.
15231 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15232 Remove, replacing with the new symbols in lisp.h. All uses changed.
15233 * fileio.c (make_temp_name):
15234 * filelock.c (lock_file_1, lock_file):
15235 * xdisp.c (message_dolog):
15236 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15237 Use pMd etc. instead.
15238 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15239 replacing the pWIDE etc. symbols removed from editfns.c.
15241 * keyboard.h (num_input_events): Now uintmax_t.
15242 This is (very slightly) less likely to mess up due to wraparound.
15245 * buffer.c: Integer signedness fixes.
15246 (alloc_buffer_text, enlarge_buffer_text):
15247 Use ptrdiff_t rather than size_t when either will do, as we prefer
15250 * alloc.c: Integer signedness and overflow fixes.
15251 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15252 (__malloc_size_t): Default to size_t, not to int.
15253 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15254 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15255 Prefer ptrdiff_t to size_t when either would do, as we prefer
15257 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15258 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15259 Now const. Initialize with values that are in range even if char
15261 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15262 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15263 These functions do the right thing with sizes > 2**32.
15264 (check_depth): Now ptrdiff_t, not int.
15265 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15266 Adjust to new way of storing sizes. Check for size overflow bugs
15268 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15269 slightly wrong anyway, as it missed one instance of
15270 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15271 (refill_memory_reserve): Omit needless cast to size_t.
15272 (mark_object_loop_halt): Mark as externally visible.
15274 * xselect.c: Integer signedness and overflow fixes.
15275 (Fx_register_dnd_atom, x_handle_dnd_message):
15276 Use ptrdiff_t, not size_t, since we prefer signed.
15277 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15278 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15279 x_dnd_atoms_size and x_dnd_atoms_length.
15281 * doprnt.c: Prefer signed to unsigned when either works.
15283 * doprnt.c (doprnt):
15285 * xdisp.c (vmessage):
15286 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15287 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15288 prefer signed arithmetic to avoid comparison confusion.
15289 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15290 but is a bit tricky.
15292 Assume freestanding C89 headers, string.h, stdlib.h.
15293 * data.c, doprnt.c, floatfns.c, print.c:
15294 Include float.h unconditionally.
15295 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15296 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15297 * regex.c: Likewise for stddef.h, string.h.
15298 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15299 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15300 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15301 (STDC_HEADERS): Remove obsolete defines.
15302 * sysdep.c: Include limits.h unconditionally.
15304 Assume support for memcmp, memcpy, memmove, memset.
15305 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15306 * regex.c (memcmp, memcpy):
15307 Remove; we assume C89 now.
15309 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15310 (__malloc_safe_bcopy): Remove; no longer needed.
15312 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15313 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15314 well either way, and we prefer signed to unsigned.
15316 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15318 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15319 closes the connection while we're reading (bug#9182).
15321 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15323 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15324 are specified (Bug#9168).
15326 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15328 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15329 Found by GCC static checking and --with-wide-int on a 32-bit host.
15331 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15333 * xdisp.c (compute_display_string_pos): Fix logic of caching
15334 previous display string position. Initialize cached_prev_pos to
15335 -1. Fixes slow-down at the beginning of a buffer.
15337 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15339 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15340 for attrs[LFACE_FONTSET_INDEX].
15342 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15344 * xml.c (parse_region): Remove unused local
15345 that was recently introduced.
15347 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15349 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15350 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15352 * xdisp.c (move_it_in_display_line_to): Record the best matching
15353 position for TO_CHARPOS while scanning the line, and restore it on
15354 exit if none of the characters scanned was an exact match.
15355 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15356 when exact match is impossible due to invisible text, and the
15357 lines are truncated.
15359 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15361 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15364 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15366 Fix a significant slow-down of cursor motion with C-n, C-p,
15367 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15368 auto-repeat under bidi redisplay in fontified buffers.
15369 * xdisp.c (compute_stop_pos_backwards): New function.
15370 (next_element_from_buffer): Call compute_stop_pos_backwards to
15371 find a suitable prev_stop when we find ourselves before
15373 (reseat): Don't look for prev_stop, as that could mean a very long
15375 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15376 <cached_disp_overlay_modiff>: Cache for last found display string
15378 (compute_display_string_pos): Return the cached position if asked
15379 about the same buffer in the same area of character positions, and
15380 the buffer wasn't changed since the time the display string
15381 position was cached.
15383 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15385 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15386 is an integer, which is important for empty lines. (Bug#9149)
15388 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15390 * frame.c (Fmodify_frame_parameters): In tty case, update the
15391 default face if necessary (Bug#4238).
15393 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15395 * editfns.c (Fstring_to_char): No need to explain what a character
15396 is in the docstring (Bug#6576).
15398 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15400 * xml.c (parse_region): Make sure we always return a tree.
15402 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15404 * xml.c (parse_region): If a document contains only comments,
15407 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15409 * xml.c (make_dom): Return comments, too.
15411 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15414 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15415 and the surrounding thread.
15416 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15417 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15418 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15420 * s/openbsd.h (BROKEN_SIGIO): Define.
15421 * unexelf.c (unexec) [__OpenBSD__]:
15422 Don't update the .mdebug section of the Alpha COFF symbol table.
15424 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15426 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15429 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15431 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15432 This fixes some race conditions on the permissions of any newly
15435 * alloc.c (valid_pointer_p): Use pipe, not open.
15436 This fixes some permissions issues when debugging.
15438 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15439 If fchown fails to set both uid and gid, try to set just gid,
15440 as that is sometimes allowed. Adjust the file's mode to eliminate
15441 setuid or setgid bits that are inappropriate if fchown fails.
15443 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15445 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15446 to compare Lisp_Objects.
15447 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15448 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15449 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15451 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15453 * lread.c (read_integer): Unread even EOF character.
15454 (read1): Likewise. Properly record start position of symbol.
15456 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15457 symbol character follows.
15459 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15461 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15462 This works around a problem with the previous change to Fcopy_file.
15463 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15464 and without this change, GCC might complain about discarding
15465 fchown's return value.
15467 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15469 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15471 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15473 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15475 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15477 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15478 it's used from the C level.
15480 * process.c: Use the same condition for POLL_FOR_INPUT in both
15481 keyboard.c and process.c (bug#1858).
15483 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15485 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15486 (Fgnutls_boot): Use it.
15488 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15490 * doc.c (Fsubstitute_command_keys): Revert last change.
15492 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15494 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15495 quotes the next character, and doesn't affect other longer
15496 sequences (bug#8935).
15498 * lread.c (syms_of_lread): Clarify that is isn't only
15499 `eval-buffer' and `eval-defun' that's affected by
15500 `lexical-binding' (bug#8460).
15502 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15504 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15505 bidi redisplay when a line includes both an image and is truncated.
15507 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15509 Fix minor problems found by static checking.
15510 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15511 (elsz): Now a signed constant, not a size_t var. We prefer signed
15512 types to unsigned, to avoid integer comparison confusion. Without
15513 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15514 "cannot optimize loop, the loop counter may overflow", a symptom
15516 * indent.c (Fvertical_motion): Mark locals as initialized.
15517 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15519 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15521 * search.c (Fre_search_backward): Mention `case-fold-search' in
15522 all the re_search_* functions (bug#8138).
15524 * keyboard.c (Fopen_dribble_file): Document when the file is
15527 2011-07-14 Eli Zaretskii <eliz@gnu.org>
15529 * bidi.c (bidi_dump_cached_states): Fix format of displaying
15532 Support bidi reordering of display and overlay strings.
15533 * xdisp.c (compute_display_string_pos)
15534 (compute_display_string_end): Accept additional argument STRING.
15535 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15536 (reseat_to_string): Initialize bidi_it->string.s and
15537 bidi_it->string.schars.
15538 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15539 NULL (avoids a crash in bidi_paragraph_init).
15540 Initialize itb.string.lstring.
15541 (init_iterator): Call bidi_init_it only of a valid
15542 buffer position was specified. Initialize paragraph_embedding to
15544 (reseat_to_string): Initialize the bidi iterator.
15545 (display_string): If we need to ignore text properties of
15546 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15547 original value of -1 will not work with bidi.)
15548 (compute_display_string_pos): First arg is now struct
15549 `text_pos *'; all callers changed. Support display properties on
15551 (compute_display_string_end): Support display properties on Lisp
15553 (init_iterator, reseat_1, reseat_to_string): Initialize the
15554 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15555 when iterating on a string not from display properties).
15556 (compute_display_string_pos, compute_display_string_end):
15557 Fix calculation of the object to scan. Fixes an error when using
15559 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15560 base_level_stop; instead, set base_level_stop to BEGV.
15561 Fixes crashes in vertical-motion.
15562 (next_element_from_buffer): Improve commentary for when
15563 the iterator is before prev_stop.
15564 (init_iterator): Initialize bidi_p from the default value of
15565 bidi-display-reordering, not from buffer-local value. Use the
15566 buffer-local value only if initializing for buffer iteration.
15567 (handle_invisible_prop): Support invisible properties on strings
15568 that are being bidi-reordered.
15569 (set_iterator_to_next): Support bidi reordering of C strings and
15571 (next_element_from_string): Support bidi reordering of Lisp
15573 (handle_stop_backwards): Support Lisp strings as well.
15574 (display_string): Support display of R2L glyph rows.
15575 Use IT_STRING_CHARPOS when displaying from a Lisp string.
15576 (init_iterator): Don't initialize it->bidi_p for strings
15578 (reseat_to_string): Initialize it->bidi_p for strings here.
15579 (next_element_from_string, next_element_from_c_string)
15580 (next_element_from_buffer): Add xassert's for correspondence
15581 between IT's object being iterated and it->bidi_it.string
15583 (face_before_or_after_it_pos): Support bidi iteration.
15584 (next_element_from_c_string): Handle the case of the first string
15585 character that is not the first one in the visual order.
15586 (get_visually_first_element): New function, refactored from common
15587 parts of next_element_from_buffer, next_element_from_string, and
15588 next_element_from_c_string.
15589 (tool_bar_lines_needed, redisplay_tool_bar)
15590 (display_menu_bar): Force left-to-right direction. Add a FIXME
15591 comment for making that be controlled by a user option.
15592 (push_it, pop_it): Save and restore the state of the
15593 bidi iterator. Save and restore the bidi_p flag.
15594 (pop_it): Iterate out of display property for string iteration as
15596 (iterate_out_of_display_property): Support iteration over strings.
15597 (handle_single_display_spec): Set up it->bidi_it for iteration
15598 over a display string, and call bidi_init_it.
15599 (handle_single_display_spec, next_overlay_string)
15600 (get_overlay_strings_1, push_display_prop): Set up the bidi
15601 iterator for displaying display or overlay strings.
15602 (forward_to_next_line_start): Don't use the shortcut if
15604 (back_to_previous_visible_line_start): If handle_display_prop
15605 pushed the iterator stack, restore the internal state of the bidi
15606 iterator by calling bidi_pop_it same number of times.
15607 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15608 and we are bidi-iterating, don't decrement the iterator position;
15609 instead, set the first_elt flag in the bidi iterator, to produce
15611 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15612 (push_display_prop): xassert that we are iterating a buffer.
15613 (push_it, pop_it): Save and restore paragraph_embedding member.
15614 (handle_single_display_spec, next_overlay_string)
15615 (get_overlay_strings_1, reseat_1, reseat_to_string)
15616 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15617 correctly. Don't assume unibyte strings are not bidi-reordered.
15618 (compute_display_string_pos)
15619 (compute_display_string_end): Fix handling the case of C string.
15620 (push_it, pop_it): Save and restore from_disp_prop_p.
15621 (handle_single_display_spec, push_display_prop): Set the
15622 from_disp_prop_p flag.
15623 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
15624 (pop_it): Call iterate_out_of_display_property only if we are
15625 popping after iteration over a string that came from a display
15626 property. Fix a typo in popping stretch info. Add an assertion
15627 for verifying that the iterator position is in sync with the bidi
15629 (handle_single_display_spec, get_overlay_strings_1)
15630 (push_display_prop): Fix initialization of paragraph direction for
15631 string when that of the parent object is not yet determined.
15632 (reseat_1): Call bidi_init_it to resync the bidi

16080 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
16082 Random fixes. E.g., (random) never returned negative values.
16083 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16084 subseconds part to the entropy, as that's a bit more random.
16085 Prefer signed to unsigned, since the signedness doesn't matter and
16086 in general we prefer signed. When given a limit, use a
16087 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16088 latter isn't right if USE_2_TAGS_FOR_INTS.
16089 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16090 not 0..VALMASK. Don't discard "excess" bits that random () returns.
16092 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
16094 * textprop.c (text_property_stickiness):
16095 Obey Vtext_property_default_nonsticky.

16102 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16103 This is more efficient than Ffile_directory_p and avoids a minor race.
16105 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16107 * buffer.c (Foverlay_put): Say what the return value is
16110 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16111 is a directory before asking whether to use the file name
16113 (barf_or_query_if_file_exists): Make the "File is a directory"
16114 error be more correct.
16116 * fns.c (Frequire): Remove the mention of the .gz files, since
16117 that's installation-specific, but keep the mention of
16118 `get-load-suffixes'.
16120 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
16122 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

16127 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
16128 (syms_of_gnutls): Remove duplicate DEFSYM for
16129 Qgnutls_bootprop_verify_hostname_error, an error for
16130 Qgnutls_bootprop_verify_error (which is no longer used).
16132 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16133 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16134 Also (re)move comments that are misplaced or no longer relevant.
16136 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16138 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16163 * lread.c (syms_of_lread): Mention single symbols defined by
16164 `defvar' or `defconst' (bug#7154).
16166 * fns.c (Frequire): Mention .el.gz files (bug#7314).
16167 (Frequire): Mention get-load-suffixes.
16169 2011-07-02 Martin Rudalics <rudalics@gmx.at>

16197 (syms_of_keymap): Defsubr make-composed-keymap.
16198 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16235 * eval.c (struct backtrace): Simplify and port the data structure.
16236 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16237 signed bit field, as this assumption is not portable and it makes
16238 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16239 "char debug_on_exit : 1" as this is not portable either; instead,
16240 use the portable "unsigned int debug_on_exit : 1". Remove unused
16241 member evalargs. Remove obsolete comments about cc bombing out.
16243 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
16245 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

16313 (emacs_fixed_get_preferred_height): Use min_width/height from
16314 frames size_hint to set minimum and natural (Bug#8919).
16315 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
16316 and use min_width/height from frames size_hint to set
16317 min_width/height (Bug#8919).

16409 * print.c (printchar, strout): Check for string overflow.
16410 (PRINTPREPARE, printchar, strout):
16411 Don't set size unless allocation succeeds.
16413 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16414 for sizes. Check for string overflow more accurately.

16428 (read_integer): Radix is now EMACS_INT, not int,
16429 to improve quality of diagnostics for out-of-range radices.
16430 Calculate buffer size correctly for out-of-range radices.
16431 (read1): Check for integer overflow in radices, and in
16432 read-circle numbers.
16433 (read_escape): Avoid int overflow.
16434 (Fload, openp, read_buffer_size, read1)
16435 (substitute_object_recurse, read_vector, read_list, map_obarray):
16436 Use ptrdiff_t, not int, for sizes.

16458 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16459 The following patches are for when GLYPH_DEBUG && !XASSERT.
16460 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16461 * dispnew.c (flush_stdout):
16462 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16463 Mark as externally visible.
16464 * dispnew.c (check_window_matrix_pointers): Now static.
16465 * dispnew.c (window_to_frame_vpos):
16466 * xfns.c (unwind_create_frame):

16473 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16475 (debug_method_add): Use va_list and vsprintf rather than relying
16476 on undefined behavior with wrong number of arguments.
16477 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16478 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16479 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16480 since we're not interested in debugging glyphs with old libraries.
16481 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16482 GCC 4.6.0's static checking.
16484 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16486 Integer overflow and signedness fixes (Bug#8873).

16502 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16503 (.bitmaps_last, struct x_output.icon_bitmap):
16504 Use ptrdiff_t, not int, for bitmap indexes.
16505 (x_allocate_bitmap_record): Check for size overflow.
16506 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16508 Use ptrdiff_t, not int, for overlay counts.
16509 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16510 * editfns.c (overlays_around, get_pos_property):
16511 * textprop.c (get_char_property_and_overlay):
16512 * xdisp.c (next_overlay_change, note_mouse_highlight):
16513 * xfaces.c (face_at_buffer_position):
16514 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16515 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16516 (Fnext_overlay_change, Fprevious_overlay_change)
16517 (mouse_face_overlay_overlaps, Foverlays_in):
16518 Use ptrdiff_t, not int, for sizes.
16519 (overlays_at, overlays_in): Check for size-calculation overflow.
16521 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16523 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16524 (x_session_initialize): Do not assume string length fits in int.
16526 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16527 This is unlikely, but can occur if DPI is outlandish.
16529 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16530 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16532 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16533 * xrdb.c (magic_file_p, search_magic_path):
16534 Omit last arg SUFFIX; it was always 0. All callers changed.
16535 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16537 * xfont.c (xfont_match): Avoid need for strlen.
16539 * xfns.c: Don't assume strlen fits in int.
16540 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16542 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16543 not unsigned long, as we prefer signed integers. All callers changed.
16544 Detect integer overflow in repeat count.
16545 (message_dolog): Don't assume print length fits in 39 bytes.
16546 (display_mode_element): Don't assume strlen fits in int.
16548 * termcap.c: Don't assume sizes fit in int and never overflow.
16549 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16550 (gobble_line): Check for size-calculation overflow.
16552 * minibuf.c (Fread_buffer):
16553 * lread.c (intern, intern_c_string):
16554 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16555 Don't assume string length fits in int.
16557 * keyboard.c (parse_tool_bar_item):
16558 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16560 * font.c: Don't assume string length fits in int.
16561 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16562 Use ptrdiff_t, not int.
16563 (font_intern_prop): Don't assume string length fits in int.
16564 Don't assume integer property fits in fixnum.
16565 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16567 * filelock.c: Fix some buffer overrun and integer overflow issues.
16568 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16569 Reformulate so as not to need the command string.
16570 Invoke gzip -cd rather than gunzip, as it's more portable.
16571 (lock_info_type, lock_file_1, lock_file):
16572 Don't assume pid_t and time_t fit in unsigned long.
16573 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16574 (current_lock_owner): Prefer signed type for sizes.
16575 Use memcpy, not strncpy, where memcpy is what is really wanted.
16576 Don't assume (via atoi) that time_t and pid_t fit in int.
16577 Check for time_t and/or pid_t out of range, e.g., via a network share.
16578 Don't alloca where an auto var works fine.
16580 * fileio.c: Fix some integer overflow issues.
16581 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16582 Don't assume string length fits in int.
16583 (directory_file_name): Don't assume string length fits in long.
16584 (make_temp_name): Don't assume pid fits in int, or that its print
16585 length is less than 20.
16587 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16589 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16591 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16593 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16594 We prefer signed integers, even for size calculations.
16596 * emacs.c: Don't assume string length fits in 'int'.
16597 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16598 (main): Don't invoke strlen when not needed.
16600 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16601 (XD_DEBUG_MESSAGE): Don't waste a byte.
16603 * callproc.c (getenv_internal_1, getenv_internal)
16604 (Fgetenv_internal):
16605 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16607 * lread.c (invalid_syntax): Omit length argument.
16608 All uses changed. This doesn't fix a bug, but it simplifies the
16609 code away from its former Hollerith-constant appearance, and it's
16610 one less 'int' to worry about when looking at integer-overflow issues.
16611 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16613 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16614 This didn't break anything, but it didn't help either.
16615 It's confusing to put a bogus integer in a place where the actual
16616 value does not matter.
16617 (LIST_END_P): Remove unused macro and its bogus comment.
16618 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16620 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16621 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16623 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16624 We prefer signed types, and the value cannot exceed the EMACS_INT
16625 range anyway (because otherwise the length would not be representable).
16626 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16627 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16628 This avoids a GCC warning when WIDE_EMACS_INT.
16630 * indent.c (sane_tab_width): New function.
16631 (current_column, scan_for_column, Findent_to, position_indentation)
16632 (compute_motion): Use it. This is just for clarity.
16633 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16635 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16637 * lisp.h (lint_assume): New macro.
16638 * composite.c (composition_gstring_put_cache):
16639 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16641 * editfns.c, insdel.c:
16642 Omit unnecessary forward decls, to simplify future changes.
16644 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16646 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16648 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16649 Use much-faster test for byte-length change.
16650 Don't assume string byte-length fits in 'int'.
16651 Check that character arg fits in 'int'.
16652 (mapcar1): Declare byte as byte, for clarity.
16654 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16656 * fns.c (concat): Catch string overflow earlier.
16657 Do not rely on integer wraparound.
16659 * dispextern.h (struct it.overlay_strings_charpos)
16660 (struct it.selective): Now EMACS_INT, not int.
16661 * xdisp.c (forward_to_next_line_start)
16662 (back_to_previous_visible_line_start)
16663 (reseat_at_next_visible_line_start, next_element_from_buffer):
16664 Don't arbitrarily truncate the value of 'selective' to int.
16666 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16668 * composite.c: Don't truncate sizes to 'int'.
16669 (composition_gstring_p, composition_reseat_it)
16670 (composition_adjust_point): Use EMACS_INT, not int.
16671 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16672 not EMACS_UINT, for indexes.
16674 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16676 * buffer.c: Include <verify.h>.
16677 (struct sortvec.priority, struct sortstr.priority):
16678 Now EMACS_INT, not int.
16679 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16680 (struct sortstr.size, record_overlay_string)
16681 (struct sortstrlist.size, struct sortlist.used):
16682 Don't truncate size to int.
16683 (record_overlay_string): Check for size-calculation overflow.
16684 (init_buffer_once): Check at compile-time, not run-time.
16686 2011-06-22 Jim Meyering <meyering@redhat.com>
16688 Don't leak an XBM-image-sized buffer
16689 * image.c (xbm_load): Free the image buffer after using it.
16691 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16694 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16695 that Sun C diagnosed.
16696 * fns.c (secure_hash): Fix pointer signedness issue.
16697 * intervals.c (static_offset_intervals): New function.
16698 (offset_intervals): Use it.
16700 2011-06-21 Leo Liu <sdl.web@gmail.com>
16703 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16706 * fns.c (secure_hash): Rename from crypto_hash_function and change
16707 the first arg to accept symbols.
16708 (Fsecure_hash): New primitive.
16709 (syms_of_fns): New symbols.
16711 2011-06-20 Deniz Dogan <deniz@dogan.se>
16713 * process.c (Fset_process_buffer): Clarify return value in
16716 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16718 * dispnew.c (add_window_display_history): Use BVAR.
16720 * xdisp.c (debug_method_add): Use BVAR.
16721 (check_window_end, dump_glyph_matrix, dump_glyph)
16722 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16724 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16727 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16728 check till after the cache is created in init_frame_faces.
16730 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16732 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16734 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16736 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16737 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16738 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16740 Improve buffer-overflow checking (Bug#8873).
16741 * fileio.c (Finsert_file_contents):
16742 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16743 Remove the old (too-loose) buffer overflow checks.
16744 They weren't needed, since make_gap checks for buffer overflow.
16745 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16746 The old code merely checked for Emacs fixnum overflow, and relied
16747 on undefined (wraparound) behavior. The new code avoids undefined
16748 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16750 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16751 Tune. Don't use wider integers than needed. Don't use alloca.
16752 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16754 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16756 * insdel.c, lisp.h (buffer_overflow): New function.
16757 (insert_from_buffer_1, replace_range, replace_range_2):
16758 * insdel.c (make_gap_larger):
16759 * editfns.c (Finsert_char):
16760 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16762 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16764 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16766 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16768 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16769 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16771 * fileio.c: Don't assume EMACS_INT fits in off_t.
16772 (emacs_lseek): New static function.
16773 (Finsert_file_contents, Fwrite_region): Use it.
16774 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16776 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16778 * fns.c: Don't overflow int when computing a list length.
16779 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16780 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16781 truncation on 64-bit hosts. Check for QUIT every
16782 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16783 faster and is responsive enough.
16784 (Flength): Report an error instead of overflowing an integer.
16785 (Fsafe_length): Return a float if the value is not representable
16786 as a fixnum. This shouldn't happen except in contrived situations.
16787 (Fnthcdr, Fsort): Don't assume list length fits in int.
16788 (Fcopy_sequence): Don't assume vector length fits in int.
16790 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16791 (header_size, word_size): New constants.
16792 (allocate_vectorlike): Don't check size overflow here.
16793 (allocate_vector): Check it here instead, since this is the only
16794 caller of allocate_vectorlike that could cause overflow.
16795 Check that the new vector's length is representable as a fixnum.
16797 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16798 The previous code was bogus. For example, next_almost_prime (32)
16799 returned 39, which is undesirable as it is a multiple of 3; and
16800 next_almost_prime (24) returned 25, which is a multiple of 5 so
16801 why was the code bothering to check for multiples of 7?
16803 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16805 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16807 Variadic C functions now count arguments with ptrdiff_t.
16808 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16809 Back then I didn't know that the Emacs coding style prefers signed int.
16810 Also, in the meantime I found a few more instances where arguments
16811 were being counted with int, which may truncate counts on 64-bit
16812 machines, or EMACS_INT, which may be unnecessarily wide.
16813 * lisp.h (struct Lisp_Subr.function.aMANY)
16814 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16815 Arg counts are now ptrdiff_t, not size_t.
16816 All variadic functions and their callers changed accordingly.
16817 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16818 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16819 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16820 * callint.c (Fcall_interactively): Check arg count for overflow,
16821 to avoid potential buffer overrun. Use signed char, not 'int',
16822 for 'varies' array, so that we needn't bother to check its size
16823 calculation for overflow.
16824 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16825 * eval.c (apply_lambda):
16826 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16827 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16828 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16830 * callint.c (Fcall_interactively): Don't use index var as event count.
16832 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16833 * mem-limits.h (SIZE): Remove; no longer used.
16835 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16837 Remove unnecessary casts.
16838 * xterm.c (x_term_init):
16839 * xfns.c (x_set_border_pixel):
16840 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16841 These aren't needed now that we assume ANSI C.
16843 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16844 It's more likely to cause problems (due to unsigned overflow)
16847 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16849 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16851 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16853 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16855 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16857 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16859 GLYPH_CODE_FACE returns EMACS_INT, not int.
16860 * dispextern.h (merge_faces):
16861 * xfaces.c (merge_faces):
16862 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16863 Don't assume EMACS_INT fits in int.
16865 * character.h (CHAR_VALID_P): Remove unused parameter.
16866 * fontset.c, lisp.h, xdisp.c: All uses changed.
16868 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16870 * fns.c (concat): Minor tuning based on overflow analysis.
16871 This doesn't fix any bugs. Use int to hold character, instead
16872 of constantly refetching from Emacs object. Use XFASTINT, not
16873 XINT, for value known to be a character. Don't bother comparing
16874 a single byte to 0400, as it's always less.
16876 * floatfns.c (Fexpt):
16877 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16879 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16882 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16884 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16885 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16886 incorrectly succeed when S was a string, because 4294967386 was
16887 truncated before it was used.
16889 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16890 Otherwise, an out-of-range integer could cause undefined behavior
16893 * composite.c: Use int, not EMACS_INT, for characters.
16894 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16895 EMACS_INT, for values that are known to be in character range.
16896 This doesn't fix any bugs but is the usual style inside Emacs and
16897 may generate better code on 32-bit machines.
16899 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16900 This is for reasons similar to the recent CHAR_STRING fix.
16901 * charset.c (Fencode_char): Check that character arg is actually
16902 a character. Pass an int to ENCODE_CHAR.
16903 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16904 wider than 'int', as a compile-time check to prevent future regressions
16907 * character.c (char_string): Remove unnecessary casts.
16909 Make sure a 64-bit char is never passed to CHAR_STRING.
16910 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16911 by silently ignoring the top 32 bits, allowing some values
16912 that were far too large to be valid characters.
16913 * character.h: Include <verify.h>.
16914 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16915 arguments are no wider than unsigned, as a compile-time check
16916 to prevent future regressions in this area.
16918 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16919 (Fsubst_char_in_region):
16921 * xdisp.c (decode_mode_spec_coding):
16922 Adjust to CHAR_STRING's new requirement.
16923 * editfns.c (Finsert_char, Fsubst_char_in_region):
16924 * fns.c (concat): Check that character args are actually
16925 characters. Without this test, these functions did the wrong
16926 thing with wildly out-of-range values on 64-bit hosts.
16928 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16929 These casts should not be needed on 32-bit hosts, either.
16930 * keyboard.c (read_char):
16931 * lread.c (Fload): Remove casts to unsigned.
16933 * lisp.h (UNSIGNED_CMP): New macro.
16934 This fixes comparison bugs on 64-bit hosts.
16935 (ASCII_CHAR_P): Use it.
16936 * casefiddle.c (casify_object):
16937 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16938 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16939 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16940 * dispextern.h (FACE_FROM_ID):
16941 * keyboard.c (read_char): Use UNSIGNED_CMP.
16943 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16944 not to EMACS_INT, to avoid GCC warning.
16946 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16948 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16949 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and

17585 instead of using explicit *_CHAR codes.
17586 (bidi_resolve_explicit, bidi_resolve_weak):

17595 (bidi_level_of_next_char): Don't try to lookup the cache for the
17596 next/previous character if nothing is cached there yet, or if we
17597 were just reseat()'ed to a new position.
17599 * xdisp.c (set_cursor_from_row): Set start and stop points
17600 according to the row's direction when priming the loop that looks
17601 for the glyph on which to display cursor.

17603 (display_prop_intangible_p): Reimplement to call
17604 handle_display_spec instead of single_display_spec_intangible_p.
17605 Accept 3 additional arguments needed by handle_display_spec.
17606 This fixes incorrect cursor motion across display property with complex

17614 (compute_display_string_pos): Accept additional argument
17615 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17616 value of a `display' property is a "replacing spec".
17617 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17618 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17619 the display property, but just return a value indicating whether
17620 the display property will replace the characters it covers.
17621 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17622 frame_window_p members of struct bidi_it.
17623 (compute_display_string_pos, compute_display_string_end):

17648 * gnutls.c: Use Emacs's memory allocators.
17649 Without this change, the gnutls library would invoke malloc etc.
17650 directly, which causes problems on non-SYNC_INPUT hosts, and which
17651 runs afoul of improving memory_full behavior. (Bug#8761)
17652 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17653 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17654 xfree instead of the default malloc, realloc, free.
17655 (Fgnutls_boot): No need to check for memory allocation failure,
17656 since xmalloc does that for us.
17658 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

17679 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17680 * alloc.c (allocate_vectorlike):
17681 Check for overflow in vector size calculations.
17682 * ccl.c (ccl_driver):
17683 Check for overflow when converting EMACS_INT to int.

17685 need to be updated by these changes.
17686 * fns.c (make_hash_table, maybe_resize_hash_table):
17687 Check for integer overflow with large hash tables.
17688 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17689 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17690 (SXHASH_REDUCE): New macro.
17691 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17692 Use it instead of discarding useful hash info with large hash values.
17693 (sxhash_float): New function.
17694 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17695 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17696 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17697 Rewrite to use FIXNUM_BITS, as this simplifies things.
17698 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17699 Adjust signatures to match updated version of code.
17700 (consing_since_gc): Now EMACS_INT, since a single hash table can
17701 use more than INT_MAX bytes.

17750 Make it possible to run ./temacs.
17752 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17753 syms_of_callproc does the same thing. Remove test for

17822 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17824 Integer overflow fixes.
17826 * dbusbind.c: Serial number integer overflow fixes.
17827 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17828 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17829 to hold a serial number that is too large for a fixnum.
17830 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17831 Check for serial numbers out of range. Decode any serial number
17832 that was so large that it became a float. (Bug#8722)
17834 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17835 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17836 Use XFASTINT rather than XUINT when numbers are nonnegative.
17837 (xd_append_arg, Fdbus_method_return_internal):
17838 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17839 arguments, check that Lisp number is nonnegative, rather than
17840 silently wrapping negative numbers around. (Bug#8722)
17841 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17844 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17846 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17848 ccl: Add integer overflow checks.
17849 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17850 (IN_INT_RANGE): New macros.
17851 (ccl_driver): Use them to check for integer overflow when
17852 decoding a CCL program. Many of the new checks are whether XINT (x)
17853 fits in int; it doesn't always, on 64-bit hosts. The new version
17854 doesn't catch all possible integer overflows, but it's an
17855 improvement. (Bug#8719)
17857 * alloc.c (make_event_array): Use XINT, not XUINT.
17858 There's no need for unsigned here.
17860 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17861 This follows up to the 2011-05-06 change that substituted uintptr_t
17862 for EMACS_INT. This case wasn't caught back then.
17864 Rework Fformat to avoid integer overflow issues.
17865 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17866 now (part of C89). Include <verify.h>.
17867 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17868 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17869 (Fformat): Avoid the prepass trying to compute sizes; it was only
17870 approximate and thus did not catch overflow reliably. Instead, walk
17871 through the format just once, formatting and computing sizes as we go,
17872 checking for integer overflow at every step, and allocating a larger
17873 buffer as needed. Keep track separately whether the format is
17874 multibyte. Keep only the most-recently calculated precision, rather
17875 than them all. Record whether each argument has been converted to
17876 string. Use EMACS_INT, not int, for byte and char and arg counts.
17877 Support field widths and precisions larger than INT_MAX. Avoid
17878 sprintf's undefined behavior with conversion specifications such as %#d
17879 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17880 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17881 formatting out-of-range floating point numbers with int
17882 formats. (Bug#8668)
17884 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17886 * data.c: Avoid integer truncation in expressions involving floats.
17887 * data.c: Include <intprops.h>.
17888 (arith_driver): When there's an integer overflow in an expression
17889 involving floating point, convert the integers to floating point
17890 so that the resulting value does not suffer from catastrophic
17891 integer truncation. For example, on a 64-bit host (* 4
17892 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17893 Do not rely on undefined behavior after integer overflow.
17895 merge count_size_as_multibyte, parse_str_to_multibyte
17896 * character.c, character.h (count_size_as_multibyte):
17897 Rename from parse_str_to_multibyte; all uses changed.
17898 Check for integer overflow.
17899 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17900 since it's now a duplicate of the other. This is more of
17901 a character than a buffer op, so better that it's in character.c.
17902 * fns.c, print.c: Adjust to above changes.
17904 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17906 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17908 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17910 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17911 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17912 (x_clipboard_manager_save): Now static.
17913 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17915 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17916 (crypto_hash_function): Now static.
17917 Fix pointer signedness problems. Avoid unnecessary initializations.
17919 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17921 * termhooks.h (Vselection_alist): Make it terminal-local.
17923 * terminal.c (create_terminal): Initialize it.
17925 * xselect.c: Support for clipboard managers.
17926 (Vselection_alist): Move to termhooks.h as terminal-local var.
17927 (LOCAL_SELECTION): New macro.
17928 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17929 (symbol_to_x_atom): Remove gratuitous arg.
17930 (x_handle_selection_request, lisp_data_to_selection_data)
17931 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17932 (x_own_selection, x_get_local_selection, x_convert_selection):
17933 New arg, specifying work frame. Use terminal-local Vselection_alist.
17934 (some_frame_on_display): Delete unused function.
17935 (Fx_own_selection_internal, Fx_get_selection_internal)
17936 (Fx_disown_selection_internal, Fx_selection_owner_p)
17937 (Fx_selection_exists_p): New optional frame arg.
17938 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17939 (x_handle_selection_clear): Don't treat other terminals with the
17940 same keyboard specially. Use the terminal-local Vselection_alist.
17941 (x_clear_frame_selections): Use Frun_hook_with_args.
17943 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17945 * xterm.h: Add support for those atoms.
17947 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17949 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17950 (converted_selections, conversion_fail_tag): New global variables.
17951 (x_selection_request_lisp_error): Free the above.
17952 (x_get_local_selection): Remove unnecessary code.
17953 (x_reply_selection_request): Args changed; handle arbitrary array
17954 of converted selections stored in converted_selections.
17955 Separate the XChangeProperty and SelectionNotify steps.
17956 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17957 (x_convert_selection): New function.
17958 (x_handle_selection_event): Simplify.
17959 (x_get_foreign_selection): Don't ignore incoming requests while
17960 waiting for an answer; this will fail when we implement
17961 SAVE_TARGETS, and seems unnecessary anyway.
17962 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17963 (Vx_sent_selection_functions): Doc fix.
17965 2011-05-26 Leo Liu <sdl.web@gmail.com>
17967 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17969 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17971 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17973 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17974 for fringe update if it has periodic bitmap.
17975 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17976 and fringe_bitmap_periodic_p.
17978 * fringe.c (get_fringe_bitmap_data): New function.
17979 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17980 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17981 row. Mark glyph row for fringe update if periodicity changed.
17983 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17984 for fringe update unless it has periodic bitmap.
17986 2011-05-25 Kenichi Handa <handa@m17n.org>
17988 * xdisp.c (get_next_display_element): Set correct it->face_id for
17989 a static composition.
17991 2011-05-24 Leo Liu <sdl.web@gmail.com>
17994 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17996 * fns.c (crypto_hash_function, Fsha1): New function.
17997 (Fmd5): Use crypto_hash_function.
17998 (syms_of_fns): Add Ssha1.
18000 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18002 * gnutls.c: Remove unused macros.
18003 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18004 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18005 Remove macros that are defined and never used.
18006 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18008 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18010 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18011 (Fx_get_selection_internal): Minor cleanup.
18012 (Fx_own_selection_internal): Rename arguments for consistency with
18015 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18017 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18019 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18021 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18023 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18025 * dispnew.c (scrolling_window): Don't exclude the case that the
18026 last enabled row in the desired matrix touches the bottom boundary.
18028 2011-05-21 Glenn Morris <rgm@gnu.org>
18030 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18031 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18032 and add some more files.
18034 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18036 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18037 report_file_error introduced by the change from 2011-05-07.
18039 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18041 * systime.h (Time): Define only if emacs is defined.
18042 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18043 where the include path doesn't have X11/X.h by default. See
18044 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18046 2011-05-20 Kenichi Handa <handa@m17n.org>
18048 * composite.c (find_automatic_composition): Fix previous change.
18050 2011-05-20 Glenn Morris <rgm@gnu.org>
18052 * lisp.mk: New file, split from Makefile.in.
18053 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18054 (shortlisp): Remove.
18055 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18057 2011-05-19 Glenn Morris <rgm@gnu.org>
18059 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18060 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18061 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18062 (lisp): Set the order to that of loadup.el.
18063 (shortlisp): Make it a copy of $lisp.
18064 (SOME_MACHINE_LISP): Remove.
18065 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18066 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18068 2011-05-18 Kenichi Handa <handa@m17n.org>
18070 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18071 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18072 (find_automatic_composition): Mostly rewrite for efficiency.
18074 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18076 * makefile.w32-in: Update dependencies.
18078 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18080 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18081 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18083 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18085 Fix some integer overflow issues, such as string length overflow.
18087 * insdel.c (count_size_as_multibyte): Check for string overflow.
18089 * character.c (lisp_string_width): Check for string overflow.
18090 Use EMACS_INT, not int, for string indexes and lengths; in
18091 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18092 the resulting string length overflows an EMACS_INT; instead,
18093 report a string overflow if no precision given. When checking for
18094 precision exhaustion, use a check that cannot possibly have
18095 integer overflow. (Bug#8675)
18096 * character.h (lisp_string_width): Adjust to new signature.
18098 * alloc.c (string_overflow): New function.
18099 (Fmake_string): Use it. This doesn't change behavior, but saves
18100 a few bytes and will simplify future changes.
18101 * character.c (string_escape_byte8): Likewise.
18102 * lisp.h (string_overflow): New decl.
18104 Fixups, following up to the user-interface timestamp change.
18105 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18106 for UI timestamps, instead of unsigned long.
18107 * msdos.c (mouse_get_pos): Likewise.
18108 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18109 * w32gui.h (Time): Define by including "systime.h" rather than by
18110 declaring it ourselves. (Bug#8664)
18112 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18113 * image.c (clear_image_cache): Likewise.
18115 * term.c (term_mouse_position): Don't assume time_t wraparound.
18117 Be more systematic about user-interface timestamps.
18118 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18119 and sometimes 'EMACS_UINT', to represent these timestamps.
18120 This change causes it to use 'Time' uniformly, as that's what X uses.
18121 This makes the code easier to follow, and makes it easier to catch
18122 integer overflow bugs such as Bug#8664.
18123 * frame.c (Fmouse_position, Fmouse_pixel_position):
18124 Use Time, not unsigned long, for user-interface timestamps.
18125 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18126 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18127 * keyboard.h (last_event_timestamp): Likewise.
18128 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18129 * menu.h (xmenu_show): Likewise.
18130 * term.c (term_mouse_position): Likewise.
18131 * termhooks.h (struct input_event.timestamp): Likewise.
18132 (struct terminal.mouse_position_hook): Likewise.
18133 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18134 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18135 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18136 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18137 what it was before.
18138 * menu.h, termhooks.h: Include "systime.h", for Time.
18140 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18141 Don't assume that the difference between two unsigned long values
18142 can fit into an integer. At this point, we know button_down_time
18143 <= event->timestamp, so the difference must be nonnegative, so
18144 there's no need to cast the result if double-click-time is
18145 nonnegative, as it should be; check that it's nonnegative, just in
18146 case. This bug is triggered when events are more than 2**31 ms
18147 apart (about 25 days). (Bug#8664)
18149 * xselect.c (last_event_timestamp): Remove duplicate decl.
18150 (x_own_selection): Remove needless cast to unsigned long.
18152 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18153 that always fit in int. Use a sentinel instead of a counter, to
18154 avoid a temp and to allay GCC's concerns about possible int overflow.
18155 * frame.h (struct frame): Use int for menu_bar_items_used
18156 instead of EMACS_INT, since it always fits in int.
18158 * menu.c (grow_menu_items): Check for int overflow.
18160 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18162 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18163 Before, the code was not consistent. These values cannot exceed
18164 2**31 - 1 so there's no need to make them unsigned.
18165 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18166 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18167 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18169 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18171 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18172 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18173 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18174 presumably because the widths might not match.
18176 * window.c (size_window): Avoid needless test at loop start.
18178 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18180 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18182 2011-05-12 Drew Adams <drew.adams@oracle.com>
18184 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18186 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18188 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18189 `width' to `bar_area_x' and `bar_area_width', respectively.
18190 (x_scroll_run): Take account of fringe background extension.
18192 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18193 Rename local vars `left' and `width' to `bar_area_x' and
18194 `bar_area_width', respectively.
18195 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18196 background extension.
18198 2011-05-10 Jim Meyering <meyering@redhat.com>
18200 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18202 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18204 * image.c (Finit_image_library): Return t for built-in image types,
18205 like pbm and xbm. (Bug#8640)
18207 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18209 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18211 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18213 * w32console.c (Fset_screen_color): Doc fix.
18214 (Fget_screen_color): New function.
18215 (syms_of_ntterm): Defsubr it.
18217 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18218 unlink the temporary file if Fcall_process didn't create it in the
18220 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18221 child process will be redirected to a file specified with `:file'.
18222 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18223 cue to call_process_cleanup not to close that handle.
18225 2011-05-07 Ben Key <bkey76@gmail.com>
18227 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18228 one of two shell specific rules, either bootstrap-temacs-CMD or
18229 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18230 to the previous implementation of the bootstrap-temacs rule.
18231 The bootstrap-temacs-CMD rule is similar to the previous
18232 implementation of the bootstrap-temacs rule except that it
18233 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18236 These changes, along with some changes to nt/configure.bat,
18237 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18238 earlier fix to add support for --cflags and --ldflags options
18239 that include quotes so that it works whether make uses cmd or
18242 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18244 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18245 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18247 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18248 a string. Handle both cases.
18249 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18250 (Fdbus_register_method): Use Qinvalid_function.
18252 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18254 * makefile.w32-in: Update dependencies.
18255 (LISP_H): Add inttypes.h and stdin.h.
18256 (PROCESS_H): Add unistd.h.
18258 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18260 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18261 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18263 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18265 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18267 * term.c (vfatal): Remove stray call to va_end.
18268 It's not needed and the C Standard doesn't allow it here anyway.
18270 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18271 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18273 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18276 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18278 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18280 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18282 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18284 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18286 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18287 * charset.c (Fdefine_charset_internal): Don't initialize
18288 charset.code_space[15]. The value was garbage, on hosts with
18289 32-bit int (Bug#8600).
18291 * lread.c (read_integer): Be more consistent with string-to-number.
18292 Use string_to_number to do the actual conversion; this avoids
18293 rounding errors and fixes some other screwups. Without this fix,
18294 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18295 (digit_to_number): Move earlier, for benefit of read_integer.
18296 Return -1 if the digit is out of range for the base, -2 if it is
18297 not a digit in any supported base. (Bug#8602)
18299 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18301 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18302 to match comment at start of function. This also removes a
18303 GCC warning about overflow in a 32+64-bit port.
18305 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18307 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18308 Reported by Stefan Monnier in
18309 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18310 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18311 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18313 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18314 (EMACS_UINTPTR): Likewise, with uintptr_t.
18316 * lisp.h: Prefer 64-bit EMACS_INT if available.
18317 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18318 on 32-bit hosts that have 64-bit int, so that they can access
18320 However, temporarily disable this change unless the temporary
18321 symbol WIDE_EMACS_INT is defined.
18323 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18325 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18326 This removes an assumption that EMACS_INT and long are the same
18327 width as pointers. The assumption is true for Emacs porting targets
18328 now, but we want to make other targets possible.
18329 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18330 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18331 In the rest of the code, change types of integers that hold casted
18332 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18333 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18334 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18335 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18336 No need to cast type when ORing.
18337 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18338 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18339 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18340 assume EMACS_INT is the same width as char *.
18341 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18342 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18343 Remove no-longer-needed casts.
18344 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18345 (xg_tool_bar_help_callback, xg_make_tool_item):
18346 Use EMACS_INTPTR to hold an integer
18347 that will be cast to void *; this can avoid a GCC warning
18348 if EMACS_INT is not the same width as void *.
18349 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18350 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18351 (current_message_1, set_message_1):
18352 Use a local to convert to proper width without a cast.
18353 * xmenu.c (dialog_selection_callback): Likewise.
18355 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18356 Also, don't assume VALBITS / RAND_BITS is less than 5,
18357 and don't rely on undefined behavior when shifting a 1 left into
18359 * lisp.h (get_random): Change signature to match.
18361 * lread.c (hash_string): Use size_t, not int, for hash computation.
18362 Normally we prefer signed values; but hashing is special, because
18363 it's better to use unsigned division on hash table sizes so that
18364 the remainder is nonnegative. Also, size_t is the natural width
18365 for hashing into memory. The previous code used 'int', which doesn't
18366 retain enough info to hash well into very large tables.
18367 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18369 * dbusbind.c: Don't possibly lose pointer info when converting.
18370 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18371 Use XPNTR rather than XHASH, so that the high-order bits of
18372 the pointer aren't lost when converting through void *.
18374 * eval.c (Fautoload): Don't double-shift a pointer.
18376 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18378 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18380 * gnutls.c (DEF_GNUTLS_FN):
18381 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18383 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18385 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18388 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18390 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18391 New version that can reserve upto 2GB of heap space.
18393 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18395 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18397 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18399 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18400 `gnutls_certificate_set_x509_key_file'.
18402 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18404 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18405 Update dependencies.
18407 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18409 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18410 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18411 Remove unused parameter `fildes'.
18412 * process.c (read_process_output, send_process): Don't pass it.
18414 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18416 Fix previous change: the library cache is defined in w32.c.
18417 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18418 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18420 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18422 Implement dynamic loading of GnuTLS on Windows.
18424 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18425 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18426 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18429 * gnutls.c (Qgnutls_dll): Define.
18430 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18431 (gnutls_*): Declare function pointers.
18432 (init_gnutls_functions): New function to initialize function pointers.
18433 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18434 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18435 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18436 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18437 (emacs_gnutls_write, emacs_gnutls_read)
18438 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18439 (Fgnutls_available_p): New function.
18440 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18441 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18442 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18444 * image.c: Include w32.h.
18445 (Vimage_type_cache): Delete.

18450 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18452 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18453 (w32_delayed_load): Move from image.c. When loading a library, record
18454 its filename in the :loaded-from property of the library id.
18455 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18456 Initialize and staticpro them.
18457 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18459 * process.c: Include lisp.h before w32.h, not after.
18460 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18461 instead of gnutls_record_check_pending.
18463 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18465 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18467 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18468 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18471 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18473 * xterm.c (x_set_frame_alpha): Do not set property on anything
18474 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18476 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18478 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18480 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18482 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
18483 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

18492 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18494 * callproc.c: Indentation fixup.
18496 * sysdep.c (wait_for_termination_1): Make static.
18497 (wait_for_termination, interruptible_wait_for_termination):
18498 Move after wait_for_termination_1.
18500 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18502 * sysdep.c (interruptible_wait_for_termination): New function
18503 which is like wait_for_termination, but allows keyboard
18506 * callproc.c (Fcall_process): Add (:file "file") as an option for
18508 (Fcall_process_region): Ditto.
18510 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18512 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18513 rather than `XVECTOR (FOO)->size'.
18515 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18516 inttypes.h, as a gnulib replacement is used if it not available in
18519 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18521 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18522 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18523 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18525 * coding.c (coding_alloc_by_realloc): Error out if destination
18526 will grow beyond MOST_POSITIVE_FIXNUM.
18527 (decode_coding_emacs_mule): Abort if there isn't enough place in
18528 charbuf for the composition carryover bytes. Reserve an extra
18529 space for up to 2 characters produced in a loop.
18530 (decode_coding_iso_2022): Abort if there isn't enough place in
18531 charbuf for the composition carryover bytes.
18533 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18535 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18536 aborting when %lld or %lll format is passed.
18537 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18538 %llo or %llx format is passed. (Bug#8545)
18540 * window.c (window_scroll_line_based): Use a marker instead of
18541 simple variables to record original value of point. (Bug#7952)
18543 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18544 produced by %s or %c overflows available buffer space. (Bug#8545)
18546 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18548 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18549 (SIZE_MAX): Move defn after all includes, as they might #define it.
18551 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18553 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18555 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18557 * keyboard.c (Qdelayed_warnings_hook): Define.
18558 (command_loop_1): Run `delayed-warnings-hook'
18559 if Vdelayed_warnings_list is non-nil.
18560 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18561 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18563 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18565 * doprnt.c (doprnt): Don't return value smaller than the buffer
18566 size if the message was truncated. (Bug#8545).
18568 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18570 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18571 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18573 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18575 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18577 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18579 * makefile.w32-in: Update dependencies.
18581 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18583 Improve `doprnt' and its usage. (Bug#8545)
18584 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18585 `format_end'. Remove support for %l as a conversion specifier.
18586 Don't use xrealloc. Improve diagnostics when the %l size modifier
18587 is used. Update the commentary.
18589 * eval.c (verror): Simplify calculation of size_t.
18591 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18594 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18596 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18599 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18601 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18602 This makes this file independent of the recent pseudovector change.
18604 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18606 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18608 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18609 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18610 Remove unused local.
18611 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18613 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18614 GCC 4.6.0 optimizes based on type-based alias analysis.
18615 For example, if b is of type struct buffer * and v of type struct
18616 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18617 != &v->size, and therefore "v->size = 1; b->size = 2; return
18618 v->size;" must therefore return 1. This assumption is incorrect
18619 for Emacs, since it type-puns struct Lisp_Vector * with many other
18620 types. To fix this problem, this patch adds a new type struct
18621 vectorlike_header that documents the constraints on layout of vectors
18622 and pseudovectors, and helps optimizing compilers not get fooled
18623 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18624 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18625 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18627 (XSETPVECTYPE): Rewrite in terms of new macro.
18628 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18629 This is a bit clearer, and further avoids the possibility of
18630 undesirable aliasing.
18631 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18632 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18633 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18634 since Lisp_Subr is a special case (no "next" field).
18635 (ASIZE): Now uses header.size rather than size.
18636 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18637 to avoid the hassle of writing XVECTOR (foo)->header.size.
18638 (struct vectorlike_header): New type.
18639 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18640 object, to help avoid aliasing.
18641 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18642 (SUBRP): Likewise, since Lisp_Subr is a special case.
18643 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18644 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18645 (struct Lisp_Hash_Table): Combine first two members into a single
18646 struct vectorlike_header member. All uses of "size" and "next" members
18647 changed to be "header.size" and "header.next".
18648 * buffer.h (struct buffer): Likewise.
18649 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18650 * frame.h (struct frame): Likewise.
18651 * process.h (struct Lisp_Process): Likewise.
18652 * termhooks.h (struct terminal): Likewise.
18653 * window.c (struct save_window_data, struct saved_window): Likewise.
18654 * window.h (struct window): Likewise.
18655 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18656 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18657 * buffer.c (init_buffer_once): Likewise.
18658 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18660 * process.c (Fformat_network_address): Use local var for size,
18663 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18665 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18666 * data.c (atof): Remove decl; no longer used or needed.
18667 (digit_to_number): Move to lread.c.
18668 (Fstring_to_number): Use new string_to_number function, to be
18669 consistent with how the Lisp reader treats infinities and NaNs.
18670 Do not assume that floating-point numbers represent EMACS_INT
18671 without losing information; this is not true on most 64-bit hosts.
18672 Avoid double-rounding errors, by insisting on integers when
18673 parsing non-base-10 numbers, as the documentation specifies.
18674 * lisp.h (string_to_number): New decl, replacing ...
18675 (isfloat_string): Remove.
18676 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18677 (read1): Do not accept +. and -. as integers; this
18678 appears to have been a coding error. Similarly, do not accept
18679 strings like +-1e0 as floating point numbers. Do not report
18680 overflow for integer overflows unless the base is not 10 which
18681 means we have no simple and reliable way to continue.
18682 Break out the floating-point parsing into a new
18683 function string_to_number, so that Fstring_to_number parses
18684 floating point numbers consistently with the Lisp reader.
18685 (digit_to_number): Move here from data.c. Make it static inline.
18686 (E_CHAR, EXP_INT): Remove, replacing with ...
18687 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18688 (string_to_number): New function, replacing isfloat_string.
18689 This function checks for valid syntax and produces the resulting
18690 Lisp float number too. Rework it so that string-to-number
18691 no longer mishandles examples like "1.0e+". Use strtoumax,
18692 so that overflow for non-base-10 numbers is reported only when
18693 there's no portable and simple way to convert to floating point.
18695 * textprop.c (set_text_properties_1): Rewrite for clarity,
18696 and to avoid GCC warning about integer overflow.
18698 * intervals.h (struct interval): Use EMACS_INT for members
18699 where EMACS_UINT might cause problems. See
18700 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18701 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18702 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18704 (offset_intervals): Tell GCC not to worry about length overflow
18705 when negating a negative length.
18707 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18708 (overrun_check_free): Likewise.
18710 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18711 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18714 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18715 (gnutls_make_error): Rename local to avoid shadowing.
18716 (gnutls_emacs_global_deinit): ifdef out; not used.
18717 (Fgnutls_boot): Use const for pointer to readonly storage.
18718 Comment out unused local. Fix pointer signedness problems.
18720 * lread.c (openp): Don't stuff size_t into an 'int'.
18721 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18722 about possible signed overflow.
18724 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18725 (GDK_KEY_g): Don't define if already defined.
18726 (xg_prepare_tooltip): Avoid pointer signedness problem.
18727 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18729 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18730 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18732 * xfns.c (Fx_window_property): Simplify a bit,
18733 to make a bit faster and to avoid GCC 4.6.0 warning.
18734 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18736 * fns.c (internal_equal): Don't assume size_t fits in int.
18738 * alloc.c (compact_small_strings): Tighten assertion a little.
18740 Replace pEd with more-general pI, and fix some printf arg casts.
18741 * lisp.h (pI): New macro, generalizing old pEd macro to other
18742 conversion specifiers. For example, use "...%"pI"d..." rather
18743 than "...%"pEd"...".
18744 (pEd): Remove. All uses replaced with similar uses of pI.
18745 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18746 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18747 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18748 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18749 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18750 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18751 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18753 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18754 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18755 * print.c (safe_debug_print, print_object): Likewise.
18756 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18758 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18759 avoiding the 0 flag, which is not portable.
18760 * process.c (Fmake_network_process): Use pI to avoid cast.
18761 * region-cache.c (pp_cache): Likewise.
18762 * xdisp.c (decode_mode_spec): Likewise.
18763 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18764 behavior on 64-bit hosts with printf arg.
18765 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18766 (x_stop_queuing_selection_requests): Likewise.
18767 (x_get_window_property): Don't truncate byte count to an 'int'
18770 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18771 here, since it parses constructs like leading '-' and spaces,
18772 which are not wanted; and it overflows with large numbers.
18773 Instead, simply match F[0-9]+, which is what is wanted anyway.
18775 * alloc.c: Remove unportable assumptions about struct layout.
18776 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18777 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18778 (allocate_vectorlike, make_pure_vector): Use the new macros,
18779 plus offsetof, to remove unportable assumptions about struct layout.
18780 These assumptions hold on all porting targets that I know of, but
18781 they are not guaranteed, they're easy to remove, and removing them
18782 makes further changes easier.
18784 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18785 This doesn't fix a bug but makes the code clearer.
18786 (string_overrun_cookie): Now const. Use initializers that
18787 don't formally overflow signed char, to avoid warnings.
18788 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18789 can cause Emacs to crash when string overrun checking is enabled.
18790 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18791 multiple of sizeof (EMACS_INT); it need not be, if
18792 alignof(EMACS_INT) < sizeof (EMACS_INT).
18793 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18795 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18822 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18824 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18825 "cast to pointer from integer of different size".
18827 Improve doprnt and its use in verror. (Bug#8545)
18828 * doprnt.c (doprnt): Document the set of format control sequences
18829 supported by the function. Use SAFE_ALLOCA instead of always
18832 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18833 is one byte too soon. Don't use xrealloc; instead xfree and
18836 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18838 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18841 * gnutls.c: Renamed global_initialized to
18842 gnutls_global_initialized. Added internals for the
18843 :verify-hostname-error, :verify-error, and :verify-flags
18844 parameters of `gnutls-boot' and documented those parameters in the
18845 docstring. Start callback support.
18846 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18847 unless a fatal error occurred. Call gnutls_alert_send_appropriate

18921 (SIZE_MAX): New macro.
18922 (doprnt): Return a size_t value. 2nd arg is now size_t.
18923 Many local variables are now size_t instead of int or unsigned.
18924 Improve overflow protection. Support `l' modifier for integer
18925 conversions. Support %l conversion. Don't assume an EMACS_INT
18926 argument for integer conversions and for %c.
18928 * lisp.h (doprnt): Restore prototype.
18930 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18931 $(SRC)/character.h.
18933 * Makefile.in (base_obj): Add back doprnt.o.
18935 * deps.mk (doprnt.o): Add back prerequisites.

18945 * callint.c (Fcall_interactively): When displaying error message
18946 about invalid control letter, pass the character's codepoint, not
18947 a pointer to its multibyte form. Improve display of the character
18948 in octal and display also its hex code.
18950 * character.c (char_string): Use %x to display the (unsigned)
18951 codepoint of an invalid character, to avoid displaying a bogus
18954 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18955 `error', not SYMBOL_NAME itself.
18957 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

19033 * dispextern.h (struct redisplay_interface): Rename param
19034 to avoid shadowing.
19035 * termhooks.h (struct terminal): Likewise.

19044 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
19045 so that we aren't warned about unused symbols.

19083 out-of-range initializers by using, for example, '\xab' rather
19086 * xgselect.c (xgselect_initialize): Check vs interface
19087 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

19152 * nsfont.m: Fixed bugs in ns_get_family and
19153 ns_descriptor_to_entity that were caused by using free to
19154 deallocate memory blocks that were allocated by xmalloc (via
19155 xstrdup). This caused Emacs to crash when compiled with
19156 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19157 --enable-checking=xmallocoverrun). xfree is now used to
19158 deallocate these memory blocks.

19567 DEFUN now defines a static function. To make the function external
19568 so that it can be used in other C modules, use the new macro DEFUE.
19569 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19570 (Finit_image_library):
19571 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
19572 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19573 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19574 Remove decls, since these functions are now static.
19575 (Funintern, Fget_internal_run_time): New decls, since these functions
19576 were already external.
19578 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19579 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
19580 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

19582 * keyboard.c, keymap.c, lread.c:
19583 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
19584 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
19585 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19586 Mark functions with DEFUE instead of DEFUN,
19587 if they are used in other modules.
19588 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19589 decls for now-static functions.
19590 * buffer.h (Fdelete_overlay): Remove decl.
19591 * callproc.c (Fgetenv_internal): Mark as internal.
19592 * composite.c (Fremove_list_of_text_properties): Remove decl.

19598 (Funintern): Remove extern decl; now in .h file where it belongs.
19599 * fileio.c (Fmake_symbolic_link): New forward static decl.
19600 * image.c (Finit_image_library): New forward static decl.
19601 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
19602 * intervals.h (Fprevious_property_change):
19603 (Fremove_list_of_text_properties): Remove decls.

19626 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19628 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19629 when at ZV. (Bug#8487)
19631 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19633 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19635 * keyboard.c (parse_tool_bar_item): Likewise.
19636 * sound.c (sound_cleanup, alsa_close): Likewise.
19637 * termcap.c (tgetent): Likewise.
19638 * xfns.c (x_default_font_parameter): Likewise.
19639 * xsettings.c (read_and_apply_settings): Likewise.
19641 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19642 (overrun_check_free): Protoize.
19644 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19646 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19647 since callers should never pass a negative size.
19648 Change the signature to match that of plain 'read' and 'write'; see
19649 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19650 * lisp.h: Update prototypes of emacs_write and emacs_read.
19652 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19654 * xdisp.c (redisplay_window): Don't try to determine the character
19655 position of the scroll margin if the window start point w->startp
19656 is outside the buffer's accessible region. (Bug#8468)
19658 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19660 Fix write-region and its subroutines for buffers > 2GB.
19661 * fileio.c (a_write, e_write): Modify declaration of arguments and
19662 local variables to support buffers larger than 2GB.
19663 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19665 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19666 argument, local variables, and return value.
19668 * lisp.h: Update prototypes of emacs_write and emacs_read.
19670 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19672 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19674 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19676 Fix more problems found by GCC 4.6.0's static checks.
19678 * xdisp.c (vmessage): Use a better test for character truncation.
19680 * charset.c (load_charset_map): <, not <=, for optimization,
19681 and to avoid potential problems with integer overflow.
19682 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19683 * casetab.c (set_identity, shuffle): Likewise.
19684 * editfns.c (Fformat): Likewise.
19685 * syntax.c (skip_chars): Likewise.
19687 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19688 This also lets GCC 4.6.0 generate slightly better loop code.
19690 * callint.c (Fcall_interactively): <, not <=, for optimization.
19691 (Fcall_interactively): Count the number of arguments produced,
19692 not the number of arguments given. This is simpler and lets GCC
19693 4.6.0 generate slightly better code.
19695 * ftfont.c: Distingish more carefully between FcChar8 and char.
19696 The previous code passed unsigned char * to a functions like
19697 strlen and xstrcasecmp that expect char *, which does not
19698 conform to the C standard.
19699 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19700 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19701 char * when the C standard requires it.
19703 * keyboard.c (read_char): Remove unused var.
19705 * eval.c: Port to Windows vsnprintf (Bug#8435).
19706 Include <limits.h>.
19707 (SIZE_MAX): Define if the headers do not.
19708 (verror): Do not give up if vsnprintf returns a negative count.
19709 Instead, grow the buffer. This ports to Windows vsnprintf, which
19710 does not conform to C99. Problem reported by Eli Zaretskii.
19711 Also, simplify the allocation scheme, by avoiding the need for
19712 calling realloc, and removing the ALLOCATED variable.
19714 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19716 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19717 But keep the doprint source code for now, as we might revamp it
19718 and use it again (Bug#8435).
19719 * lisp.h (doprnt): Remove.
19720 * Makefile.in (base_obj): Remove doprnt.o.
19721 * deps.mk (doprnt.o): Remove.
19723 error: Print 32- and 64-bit integers portably (Bug#8435).
19724 Without this change, on typical 64-bit hosts error ("...%d...", N)
19725 was used to print both 32- and 64-bit integers N, which relied on
19726 undefined behavior.
19727 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19728 * lisp.h (error, verror): Mark as printf-like functions.
19729 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19730 Report overflow in size calculations when allocating printf buffer.
19731 Do not truncate output string at its first null byte.
19732 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19733 Truncate the output at a character boundary, since vsnprintf does not
19735 * charset.c (check_iso_charset_parameter): Convert internal
19736 character to string before calling 'error', since %c now has the
19738 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19739 overflow when computing char to be passed to 'error'. Do not
19740 pass Lisp_Object to 'error'; pass the integer instead.
19741 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19742 formatted with plain %d.
19744 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19746 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19748 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19750 * xterm.c (x_catch_errors): Remove duplicate declaration.
19752 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19754 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19756 2011-04-10 Jim Meyering <meyering@redhat.com>
19758 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19759 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19760 return ssize_t not "int", and use size_t as the buffer length.
19761 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19762 * gnutls.h: Update declarations.
19763 * process.c (read_process_output): Use ssize_t, to match.
19764 (send_process): Likewise.
19766 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19768 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19770 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19772 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19773 Use unsigned char, to match FcChar8 type definition.
19775 * xterm.c (handle_one_xevent):
19776 * xmenu.c (create_and_show_popup_menu):
19777 * xselect.c (x_decline_selection_request)
19778 (x_reply_selection_request): Avoid type-punned deref of X events.
19780 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19782 Fix some uses of `int' instead of EMACS_INT.
19783 * search.c (string_match_1, fast_string_match)
19784 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19785 (scan_buffer, find_next_newline_no_quit)
19786 (find_before_next_newline, search_command, Freplace_match)
19787 (Fmatch_data): Make some `int' variables be EMACS_INT.
19789 * xdisp.c (display_count_lines): 3rd argument and return value now
19790 EMACS_INT. All callers changed.
19791 (pint2hrstr): Last argument is now EMACS_INT.
19793 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19794 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19795 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
19796 (decode_coding_utf_16, decode_coding_emacs_mule)

19798 (decode_coding_ccl, decode_coding_charset)
19799 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
19800 (decode_coding_iso_2022, decode_coding_emacs_mule)
19801 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
19802 <char_offset, last_offset>: Declare EMACS_INT.

19805 (encode_designation_at_bol, encode_coding_iso_2022)
19806 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19807 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19809 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19810 (encode_invocation_designation): Last argument P_NCHARS is now
19812 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19813 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19815 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19818 * ccl.c (Fccl_execute_on_string): Declare some variables
19821 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19823 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19825 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19827 * process.c (Fformat_network_address): Doc fix.
19829 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19831 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19833 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19835 * keyboard.c (read_char): Call Lisp function help-form-show,
19836 instead of using internal_with_output_to_temp_buffer.
19837 (Qhelp_form_show): New var.
19838 (syms_of_keyboard): Use DEFSYM macro.
19840 * print.c (internal_with_output_to_temp_buffer): Function deleted.
19842 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
19844 2011-04-06 Chong Yidong <cyd@stupidchicken.com>

19851 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19853 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19855 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19857 Fix more problems found by GCC 4.6.0's static checks.

19863 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19865 * xdisp.c (vmessage): Mark as a printf-like function.
19867 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19869 * sound.c (sound_warning): Don't crash if arg contains a printf format.

19872 printf-like functions.
19873 (tiff_load): Add casts to remove these marks before passing them
19874 to system-supplied API.
19876 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19878 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19879 This avoids several warnings with gcc -Wstrict-overflow.
19880 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19881 directly, rather than having caller test rule sign. This avoids
19882 some unnecessary tests.
19883 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19884 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19885 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19887 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19888 (xfont_open): Avoid unnecessary tests.
19890 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19892 * composite.h, composite.c (composition_gstring_put_cache):
19893 Use EMACS_INT, not int, for length.

19899 by using the new macro.
19901 * textprop.c (set_text_properties_1): Change while to do-while,
19902 since the condition is always true at first.
19904 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19905 (interval_deletion_adjustment): Return unsigned value.
19908 * process.c (list_processes_1, create_pty, read_process_output):

19918 (update_syntax_table): Use unsigned instead of int.
19920 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19921 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19922 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19924 * print.c (print_error_message): Avoid int overflow.
19926 * font.c (font_list_entities): Redo for clarity,
19927 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19929 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19930 (font_score): Avoid potential overflow in diff calculation.
19932 * fns.c (substring_both): Remove var that is set but not used.
19933 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19935 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19937 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19938 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19939 can always succeed if overflow has undefined behavior.
19941 * search.c (boyer_moore, wordify): Remove vars set but not used.
19942 (wordify): Omit three unnecessary tests.
19944 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19945 All callers changed. This avoids the need for an unused var.
19947 * casefiddle.c (casify_region): Remove var that is set but not used.
19949 * dired.c (file_name_completion): Remove var that is set but not used.
19951 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19953 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19954 (Finsert_file_contents): Remove unnecessary code checking fd.
19956 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19957 Check for integer overflow on size calculations.
19959 * buffer.c (Fprevious_overlay_change): Remove var that is set
19962 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19963 Remove vars that are set but not used.
19964 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19965 (timer_check_2): Mark vars as initialized.
19967 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19969 * image.c (lookup_image): Remove var that is set but not used.
19970 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19972 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19973 that are set but not used.
19975 * xfns.c (make_invisible_cursor): Don't return garbage
19976 if XCreateBitmapFromData fails (Bug#8410).
19978 * xselect.c (x_get_local_selection, x_handle_property_notify):
19979 Remove vars that are set but not used.
19981 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19982 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19984 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19985 Remove var that is set but not used.
19986 (scroll_bar_windows_size): Now size_t, not int.
19987 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19988 Check for overflow.
19990 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19991 (map_tty_color) [!defined MSDOS]: Likewise.
19993 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19995 * coding.c: Remove vars that are set but not used.
19996 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19997 All callers changed.
19998 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19999 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20000 (decode_coding_charset): Remove vars that are set but not used.
20002 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20003 that is set but not used.
20005 * print.c (print_object): Remove var that is set but not used.
20007 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20008 The gnulib version avoids calling malloc in the usual case,
20009 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20010 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20011 * filelock.c (current_lock_owner): Likewise.

20014 (emacs_no_realloc_allocator): New static constant.
20015 (emacs_readlink): New function.
20016 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

20043 do not dereference NULL upon failed strdup
20044 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20045 (ns_get_family): Likewise.
20047 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

20053 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20056 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20058 Add lexical binding.

20069 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20071 (syms_of_lread): Declare `lexical-binding'.
20073 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20075 * keyboard.c (eval_dyn): New fun.
20076 (menu_item_eval_property): Use it.
20078 * image.c (parse_image_spec): Use Ffunctionp.
20080 * fns.c (concat, mapcar1): Accept byte-code-functions.
20082 * eval.c (Fsetq): Handle lexical vars.

20084 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20085 (FletX, Flet): Obey lexical binding.
20086 (Fcommandp): Handle closures.
20087 (Feval): New `lexical' arg.
20088 (eval_sub): New function extracted from Feval. Use it almost
20089 everywhere where Feval was used. Look up vars in lexical env.
20091 (Ffunctionp): Move from subr.el.
20092 (Ffuncall): Handle closures.
20093 (apply_lambda): Remove `eval_flags'.
20094 (funcall_lambda): Handle closures and new byte-code-functions.
20095 (Fspecial_variable_p): New function.
20096 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20097 but without exporting it to Lisp.
20099 * doc.c (Fdocumentation, store_function_docstring):
20100 * data.c (Finteractive_form): Handle closures.
20102 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20105 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20107 (exec_byte_code): New function extracted from Fbyte_code to handle new
20108 calling convention for byte-code-functions. Add new byte-codes.
20110 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

20116 * xdisp.c (redisplay_internal): Fix prototype.
20118 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20120 * xdisp.c (SCROLL_LIMIT): New macro.

20122 Limit scrolling to 100 screen lines.
20123 (redisplay_window): Even when falling back on "recentering",
20124 position point in the window according to scroll-conservatively,
20125 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20127 (try_scrolling): When point is above the window, allow searching
20128 as far as scroll_max, or one screenful, to compute vertical
20129 distance from PT to the scroll margin position. This prevents
20130 try_scrolling from unnecessarily failing when
20131 scroll-conservatively is set to a value slightly larger than the
20132 window height. Clean up the case of PT below the margin at bottom
20133 of window: scroll_max can no longer be INT_MAX. When aggressive
20134 scrolling is in use, don't let point enter the opposite scroll
20135 margin as result of the scroll.
20136 (syms_of_xdisp) <scroll-conservatively>: Document the
20137 threshold of 100 lines for never-recentering scrolling.

20147 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20149 * indent.c (Fvertical_motion):
20150 * window.c (window_scroll_pixel_based, Frecenter):
20151 Don't pass `need_y_p' to `move_it_by_lines'.
20153 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20155 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20156 steal a few bits to be more compact.
20157 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20158 Remove unneeded casts.
20160 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20162 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20164 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20165 binding" message (bug#7967).
20167 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20169 Fix more problems found by GCC 4.6.0's static checks.
20171 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20172 Remove unused local var.
20174 * editfns.c (Fmessage_box): Remove unused local var.
20176 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20177 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20178 Omit unused local vars.
20179 * window.c (shrink_windows): Omit unused local var.
20180 * menu.c (digest_single_submenu): Omit unused local var.
20181 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20182 Omit unused local var.
20184 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20185 Don't assume string length fits in int.
20186 (keyremap_step, read_key_sequence): Use size_t for sizes.

20189 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20190 instead of alloca (Bug#8344).
20192 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20193 (Fbacktrace_frame): Don't assume nframes fits in int.
20195 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

20202 * cm.c (calccost): Turn while-do into do-while, for clarity.
20204 * keyboard.c (syms_of_keyboard): Use the same style as later
20205 in this function when indexing through an array. This also
20206 works around GCC bug 48267.
20208 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20210 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20212 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20213 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20215 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20216 This avoids undefined behavior on integer overflow, and is a bit
20217 more convenient anyway since it is compared to a size_t variable.
20219 Variadic C functions now count arguments with size_t, not int.
20220 This avoids an unnecessary limitation on 64-bit machines, which
20221 caused (substring ...) to crash on large vectors (Bug#8344).

20231 * fns.c (concat): Likewise.
20232 * frame.c (x_set_frame_parameters): Likewise.
20233 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20234 0 if not found, not -1. All callers changed.
20236 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20237 (stack_copy_size): Now size_t, not int.
20238 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20240 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

20259 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20260 don't set the hook to nil, but remove the offending function instead.

20262 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20263 Vcommand_hook_internal.

20266 (funcall_nil, funcall_not): New functions.
20267 (run_hook_with_args): Call each function through a `funcall' argument.

20446 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20447 unconditionally since it does the check itself.
20449 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20451 Fix more problems found by GCC 4.5.2's static checks.
20453 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20454 the first time through the loop, since we know p0 < p1 then.
20455 This also avoids a gcc -Wstrict-overflow warning.
20457 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20458 leading to a memory leak, possible in functions like
20459 load_charset_map_from_file that can allocate an unbounded number
20460 of objects (Bug#8318).
20462 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20463 that could (at least in theory) be that large.
20465 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20466 This is less likely to overflow, and avoids undefined behavior if
20467 overflow does occur. All callers changed. Use strtoul to scan
20468 for the unsigned long integer.
20469 (pint2hrstr): Simplify and tune code slightly.
20470 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
20472 * scroll.c (do_scrolling): Work around GCC bug 48228.
20473 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
20475 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
20476 This also avoids a warning with gcc -Wstrict-overflow.
20477 (validate_x_resource_name): Simplify count usage.
20478 This also avoids a warning with gcc -Wstrict-overflow.
20480 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20483 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20485 * process.c (Fmake_network_process): Use socklen_t, not int,
20486 where POSIX says socklen_t is required in portable programs.
20487 This fixes a porting bug on hosts like 64-bit HP-UX, where
20488 socklen_t is wider than int (Bug#8277).
20489 (Fmake_network_process, server_accept_connection):
20490 (wait_reading_process_output, read_process_output):
20493 * process.c: Rename or move locals to avoid shadowing.

20503 Make tparam.h and terminfo.c consistent.
20504 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20505 Include tparam.h instead, since it declares them.
20506 * cm.h (PC): Remove extern decl; tparam.h now does this.
20507 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20508 * terminfo.c: Include tparam.h, to check interfaces.
20509 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20510 (tparam): Adjust signature to match interface in tparam.h;
20511 this removes some undefined behavior. Check that outstring and len
20512 are zero, which they always are with Emacs.
20513 * tparam.h (PC, BC, UP): New extern decls.
20515 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20516 (xftfont_open): Rename locals to avoid shadowing.
20518 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

20528 * xml.c (make_dom): Now static.
20530 * composite.c (composition_compute_stop_pos): Rename local to
20532 (composition_reseat_it): Remove unused locals.
20533 (find_automatic_composition, composition_adjust_point): Likewise.
20534 (composition_update_it): Mark var as initialized.
20535 (find_automatic_composition): Mark vars as initialized,
20536 with a FIXME (Bug#8290).

20539 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
20540 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20541 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20542 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20543 to avoid shadowing.
20545 * textprop.c (property_change_between_p): Remove; unused.
20547 * intervals.c (interval_start_pos): Now static.
20549 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20552 Rename locals to avoid shadowing.
20554 * sound.c (wav_play, au_play, Fplay_sound_internal):
20555 Fix pointer signedness.
20556 (alsa_choose_format): Remove unused local var.
20557 (wav_play): Initialize a variable to 0, to prevent undefined
20558 behavior (Bug#8278).
20560 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20562 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20564 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20565 clobbering (Bug#8298).
20566 * sysdep.c (sys_subshell): Likewise.
20567 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20569 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20570 This should get cleaned up, so that child_setup has the
20571 same signature on all platforms.
20573 * callproc.c (call_process_cleanup): Now static.
20574 (relocate_fd): Rename locals to avoid shadowing.
20576 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20578 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20579 not to be necessary, and produces flickering.
20581 2011-03-20 Glenn Morris <rgm@gnu.org>
20583 * config.in: Remove file.
20585 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20587 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20588 are now in src/globals.h.
20589 (syms_of_minibuf): Remove spurious & from previous change.
20591 2011-03-20 Leo Liu <sdl.web@gmail.com>
20593 * minibuf.c (completing-read-function): New variable.
20594 (completing-read-default): Rename from completing-read.
20595 (completing-read): Call completing-read-function.
20597 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
20599 * xfaces.c (Fx_load_color_file):
20600 Read color file from absolute filename (bug#8250).
20602 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
20604 * makefile.w32-in: Update dependencies.
20606 2011-03-17 Eli Zaretskii <eliz@gnu.org>
20608 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

20615 (sigchld_handler): Now static.
20617 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20618 That way, the code declares only the vars that it needs.
20619 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
20620 * s/cygwin.h (PTY_ITERATION): Likewise.
20621 * s/darwin.h (PTY_ITERATION): Likewise.

20628 (CONSTANTLIM): Remove; unused.
20629 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20630 Define only if needed.
20632 * unexelf.c (unexec): Name an expression,
20633 to avoid gcc -Wbad-function-cast warning.
20634 Use a different way to cause a compilation error if anyone uses
20635 n rather than nn, a way that does not involve shadowing.
20636 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20638 * deps.mk (unexalpha.o): Remove; unused.
20640 New file unexec.h, the (simple) interface for unexec (Bug#8267).
20641 * unexec.h: New file.
20642 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
20643 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
20644 Depend on unexec.h.
20645 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
20646 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
20647 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
20648 Change as necessary to match prototype in unexec.h.
20650 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

20667 (font_sort_entities): Mark var as initialized.
20669 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
20671 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

20695 * callint.c (quotify_arg, quotify_args): Now static.
20696 (Fcall_interactively): Rename locals to avoid shadowing.
20697 Use const pointer when appropriate.

20703 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
20704 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20705 some of which prompt warnings from gcc -Wbad-function-cast.
20706 (Fformat_time_string, Fencode_time, Finsert_char):
20707 (Ftranslate_region_internal, Fformat):
20708 Rename or remove local vars to avoid shadowing.
20709 (Ftranslate_region_internal): Mark var as initialized.
20711 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20714 * lisp.h (eassert): Check that the argument compiles, even if
20715 ENABLE_CHECKING is not defined.
20717 * data.c (Findirect_variable): Name an expression, to avoid
20718 gcc -Wbad-function-cast warning.
20719 (default_value, arithcompare, arith_driver, arith_error): Now static.

20727 Rename locals to avoid shadowing.
20728 (mark_stack): Move local variables into the #ifdef region where
20730 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
20731 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
20733 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
20734 (GC_STRING_CHARS): Remove; not used.
20735 (Fmemory_limit): Cast sbrk's returned value to char *.
20737 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
20738 avoids undefined behavior in theory.
20740 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
20742 Use functions, not macros, for up- and down-casing (Bug#8254).
20743 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20744 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20745 to use the following functions instead of these macros.
20746 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20747 EMACS_INT, since callers assume the returned value fits in int.
20748 (upcase1): Likewise, for UPCASE_TABLE.
20749 (uppercasep, lowercasep, upcase): New static inline functions.
20750 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
20751 the race-condition problem in the old DOWNCASE.
20753 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

20757 Remove unused local vars.
20758 (FREE_VAR): Rewrite so as not to use empty "else",
20759 which gcc can warn about.
20760 (regex_compile, re_match_2_internal): Mark locals as initialized.
20761 (RETALLOC_IF): Define only if needed.
20762 (WORDCHAR_P): Likewise. This one is never needed, but is used
20763 only in a comment talking about a compiler bug, so put inside
20764 the #if 0 of that comment.
20765 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20766 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
20769 * search.c (boyer_moore): Rename locals to avoid shadowing.
20770 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

20781 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
20783 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
20784 Rename locals to avoid shadowing.
20785 (Fvertical_motion): Mark locals as initialized.
20787 * casefiddle.c (casify_object, casify_region): Now static.
20788 (casify_region): Mark local as initialized.
20790 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
20792 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20793 New macros, so that the caller can use some names other than
20794 gcpro1, gcpro2, etc.
20795 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20797 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20798 argument, for consistency with GCPRO2_VAR, etc: it is now the
20799 prefix of the variable, not the variable itself. All uses
20801 * dired.c (directory_files_internal, file_name_completion):
20802 Rename locals to avoid shadowing.
20804 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20805 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20806 dired.c's scmp function, had undefined behavior.
20807 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20808 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20809 * buffer.h: ... to here, because these macros use current_buffer,
20810 and the new implementation with inline functions needs to have
20811 current_buffer in scope now, rather than later when the macros
20813 (downcase, upcase1): New static inline functions.
20814 (DOWNCASE, UPCASE1): Reimplement using these functions.
20815 This avoids undefined behavior in expressions like
20816 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20817 from race conditions in accessing the global variables
20818 case_temp1 and case_temp2.
20819 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20820 * lisp.h (case_temp1, case_temp2): Remove their decls.
20821 * character.h (ASCII_CHAR_P): Move from here ...
20822 * lisp.h: ... to here, so that the inline functions mentioned
20823 above can use them.
20825 * dired.c (directory_files_internal_unwind): Now static.
20827 * fileio.c (file_name_as_directory, directory_file_name):
20828 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
20830 (file_name_as_directory): Use const pointers when appropriate.
20831 (Fexpand_file_name): Likewise. In particular, newdir might
20832 point at constant storage, so make it a const pointer.
20833 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20834 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20836 (Fset_file_times, Finsert_file_contents, auto_save_error):
20837 Rename locals to avoid shadowing.
20839 * minibuf.c (choose_minibuf_frame_1): Now static.
20840 (Ftry_completion, Fall_completions): Rename or remove locals
20841 to avoid shadowing.
20843 * marker.c (bytepos_to_charpos): Remove; unused.
20845 * lisp.h (verify_bytepos, count_markers): New decls,
20846 so that gcc does not warn that these functions aren't declared.
20848 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20849 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20850 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20851 (copy_text): Remove unused local var.
20853 * filelock.c (within_one_second): Now static.
20854 (lock_file_1): Rename local to avoid shadowing.
20856 * buffer.c (fix_overlays_before): Mark locals as initialized.
20857 (fix_start_end_in_overlays): Likewise. This function should be
20858 simplified by using pointers-to-pointers, but that's a different
20860 (switch_to_buffer_1): Now static.
20861 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20862 (report_overlay_modification): Rename locals to avoid shadowing.
20864 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
20865 Fix pointer signedness issue.
20866 (sys_subshell): Mark local as volatile if checking for lint,
20867 to suppress a gcc -Wclobbered warning that does not seem to be right.
20868 (MAXPATHLEN): Define only if needed.
20870 * process.c (serial_open, serial_configure): Move decls from here ...
20871 * systty.h: ... to here, so that they can be checked.
20873 * fns.c (get_random, seed_random): Move extern decls from here ...
20874 * lisp.h: ... to here, so that they can be checked.
20876 * sysdep.c (reset_io): Now static.
20877 (wait_for_termination_signal): Remove; unused.
20879 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
20880 (copy_keymap_item, append_key, push_text_char_description):
20882 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
20883 (DENSE_TABLE_SIZE): Remove; unused.
20884 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20885 (describe_map_tree):
20886 Rename locals to avoid shadowing.
20888 * keyboard.c: Declare functions static if they are not used elsewhere.
20889 (echo_char, echo_dash, cmd_error, top_level_2):
20890 (poll_for_input, handle_async_input): Now static.
20891 (read_char, kbd_buffer_get_event, make_lispy_position):
20892 (make_lispy_event, make_lispy_movement, apply_modifiers):
20893 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
20894 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
