3 * syntax.c (scan_sexps_forward): Fix byte position calculation
4 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
6 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
8 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
11 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
13 Minor hashing refactoring.
14 * fns.c (SXHASH_REDUCE): Move to lisp.h.
15 (sxhash_float): Return EMACS_UINT, for consistency with the other
17 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
18 non-static inline function and therefore can't use static vars.
19 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
20 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
21 with the other hash functions.
23 2013-02-09 Eli Zaretskii <eliz@gnu.org>
25 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
26 XXXXXX part of the temporary file pattern is not downcased even
27 when w32-downcase-file-names is non-nil. (Bug#13661)
29 * xdisp.c (decode_mode_spec): Remove handling of %t.
31 * msdos.c (careadlinkatcwd): Remove.
33 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>

39 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
41 * search.c (scan_buffer): Calculate end byte position just once.
42 (scan_newline): Do not recalculate start_byte.
43 (search_command): Use eassert.
44 * syntax.c (struct lisp_parse_state): New member location_byte.
45 (scan_sexps_forward): Record from_byte and avoid redundant
46 character to byte position calculation ...
47 (Fparse_partial_sexp): ... here. Break too long line.
49 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
51 * lisp.h (make_uninit_vector): New function.
52 * alloc.c (Fvector, Fmake_byte_code):
53 * ccl.c (Fregister_ccl_program):
54 * charset.c (Fdefine_charset_internal, define_charset_internal):
55 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
56 * composite.c (syms_of_composite):
57 * font.c (Fquery_font, Ffont_info, syms_of_font):

62 * syntax.c (init_syntax_once):
63 * w32unsubscribe.c (uniscribe_shape):
64 * window.c (Fcurrent_window_configuration):
65 * xfaces.c (Fx_family_fonts):
66 * xselect.c (selection_data_to_lisp_data): Use it.
68 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
70 * coding.c (Fdefine_coding_system_internal): Use AREF where
71 argument is known to be a vector.
72 * fns.c (Flocale_info): Likewise for ASET.
73 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
74 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
76 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
78 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
81 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
82 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
83 updateCollectionBehaviour.
85 * nsterm.m (NEW_STYLE_FS): Remove.
86 (ns_last_use_native_fullscreen): New variable.
87 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.

89 if isFullscreen returns YES.
90 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
91 (check_native_fs): New function.
92 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
93 (ns_term_init): Remove NEW_STYLE_FS.

104 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
105 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
106 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
107 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
108 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
109 (syms_of_nsterm): Add ns-use-native-fullscreen.
111 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
113 * fileio.c (Qchoose_write_coding_system): Now static.
115 2013-02-04 Eli Zaretskii <eliz@gnu.org>
117 * xdisp.c (window_buffer_changed): region_showing can be negative,
118 which still means region is being displayed.
119 (redisplay_internal): Resurrect code that forced redisplay of the
120 whole window when showing region and the mark has changed. Record
121 the new mark position to allow redisplay optimizations.
122 (display_line): If it->region_beg_charpos is non-zero, set the
123 window's region_showing member to -1. (Bug#13623) (Bug#13626)
125 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
126 not bitfield of 1 bit.
128 2013-02-03 Daniel Colascione <dancol@dancol.org>
130 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
131 daemon mode works on cygw32 when Emacs is installed and not just
134 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
136 Avoid file time stamp bug on MS-Windows (Bug#13149).
137 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
138 as FAT32 doesn't update time stamps when truncating them.
139 Also, check that a file time stamp is not a multiple of 100 ns;
140 this should catch all instances of the problem on MS-Windows,
141 as its native file system resolution is 100 ns or worse, and
142 checking for a non-multiple of 100 ns should impose only a small
143 overhead on systems with ns resolution.
145 2013-02-02 Eli Zaretskii <eliz@gnu.org>
147 Avoid encoding file names on MS-Windows when they need to be run
148 through dostounix_filename.
149 * w32.c (normalize_filename): Accept an additional argument
150 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
151 downcase it even if w32-downcase-file-names is non-nil.
152 (dostounix_filename): Accept an additional argument MULTIBYTE and
153 pass it to normalize_filename.
154 (emacs_root_dir): Adjust.
156 * msdos.h (dostounix_filename): Adjust prototype.
158 * w32.h (dostounix_filename): Adjust prototype.
160 * msdos.c (dostounix_filename): Accept an additional argument and
162 (init_environment): Adjust callers of dostounix_filename.
164 * fileio.c (Ffile_name_directory, file_name_as_directory)
165 (directory_file_name, Fexpand_file_name)
166 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
168 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
170 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
171 variables, as egetenv is case-insensitive for DOS_NT.
173 * dired.c (file_name_completion): Don't call Fdirectory_file_name
174 with an encoded file name.
176 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
177 calls to dostounix_filename.
179 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
181 * unexw32.c (unexec): Adjust call to dostounix_filename.
183 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
185 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
188 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
191 * callproc.c (Fcall_process): Make sure program name in PATH and
192 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
193 is passed to exec/spawnve, which fails unless the file-name
196 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
197 even if w32-quote-process-args is nil.
199 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
201 Fix timestamp bug when write-region appends nothing (Bug#13149).
202 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
203 the file's time stamp doesn't change if Emacs happens to write nothing
204 to the file, and on a buggy file system this could cause Emacs to
205 incorrectly infer that the file system doesn't have the bug.
206 Avoid this problem by inhibiting the inference in this case.
208 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
210 * window.h (struct window): Convert base_line_number, base_line_pos
211 and column_number_displayed members from Lisp_Object to ptrdiff_t.
212 Convert region_showing member from Lisp_Object to bitfield.
213 Remove sequence_number member. Adjust comments.
214 * window.c (sequence_number): Remove.
215 (make_window): Initialize column_number_displayed.
216 * print.c (print_object): Follow the printed representation of
217 frames and print window pointer to distinguish between windows.
218 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
219 * xdisp.c (wset_base_line_number, wset_base_line_pos)
220 (wset_column_number_displayed, wset_region_showing): Remove.
221 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
222 (try_scrolling, try_cursor_movement, redisplay_window)
223 (try_window_reusing_current_matrix, try_window_id, display_line)
224 (display_mode_lines, decode_mode_spec): Adjust users.
225 * .gdbinit (pwinx): Do not print sequence_number.
227 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
229 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
230 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
231 * dired.c: Include <fcntl.h>.
232 (open_directory): New function, which uses open and fdopendir
233 rather than opendir. DOS_NT platforms still use opendir, though.
234 (directory_files_internal, file_name_completion): Use it.
235 (file_attributes): New function, with most of the old Ffile_attributes.
236 (directory_files_internal, Ffile_attributes): Use it.
237 (file_attributes, file_name_completion_stat): First arg is now fd,
238 not dir name. All uses changed. Use fstatat rather than lstat +
240 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
241 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
242 (emacs_readlinkat): New function, with much of the old
243 Ffile_symlink_p, but with an fd argument for speed.
244 It uses readlinkat rather than careadlinkatcwd, so that it
245 need not assume the working directory.
246 (Ffile_symlink_p): Use it.
247 * filelock.c (current_lock_owner): Use emacs_readlinkat
248 rather than emacs_readlink.
249 * lisp.h (emacs_readlinkat): New decl.
250 (READLINK_BUFSIZE, emacs_readlink): Remove.
251 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
252 (emacs_norealloc_allocator, emacs_readlink): Remove.
253 This stuff is moved to fileio.c.
254 * w32.c (fstatat, readlinkat): New functions.
255 (careadlinkat): Don't check that fd == AT_FDCWD.
256 (careadlinkatcwd): Remove; no longer needed.
258 2013-01-31 Glenn Morris <rgm@gnu.org>
260 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
261 (Fwrite_region): Update for new choose_write_coding_system args.
262 Move the last piece of choose_write_coding_system here. (Bug#13522)
263 (syms_of_fileio): Add choose-write-coding-system.
265 2013-01-30 Eli Zaretskii <eliz@gnu.org>
267 * w32.c (sys_open): Zero out the flags for the new file descriptor.
268 (sys_close): Zero out the flags for the file descriptor before
269 closing it. (Bug#13546)
271 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
272 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
273 CharNextExA and CharPrevExA to iterate over file names encoded in
276 * w32.c (w32_get_long_filename, init_environment, readlink):
277 Support file names encoded in DBCS codepages.
278 (readlink): Use the current file-name-coding-system, not the ANSI
279 codepage, to decode and handle targets of symlinks.
281 2013-01-28 Eli Zaretskii <eliz@gnu.org>
283 * w32.c (opendir): Now accepts a 'const char *'.
285 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
287 Remove obsolete redisplay code. See the discussion at
288 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
289 * dispnew.c (preemption_period, preemption_next_check): Remove.
290 (Vredisplay_preemption_period): Likewise.
291 (update_frame, update_single_window, update_window, update_frame_1):
292 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
293 used, following the 2012-06-22 change.
295 2013-01-25 Eli Zaretskii <eliz@gnu.org>
297 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
299 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
301 * font.c (num_fonts): Remove the leftover from old
302 debugging code. Adjust comment style here and there.
303 * insdel.c (insert_1): Remove.
304 * lisp.h (insert_1): Remove prototype.
305 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
307 2013-01-25 Eli Zaretskii <eliz@gnu.org>
309 * w32.c (max_filename_mbslen): New function.
310 (normalize_filename, readdir): Use it to detect locales where ANSI
311 encoding of file names uses a double-byte character set (DBCS).
312 If a DBCS encoding is used, advance by characters using
313 CharNextExA, instead of incrementing a 'char *' pointer. Use
314 _mbslwr instead of _strlwr. (Bug#13515)
316 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
317 request of memory reservation to 1.7GB. (Bug#13065)
319 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
321 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
322 at check_extra_latin label. (Bug#13505)
324 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
326 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
327 Avoid redundant calls to strlen.
329 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
331 Drop async_visible and async_iconified fields of struct frame.
332 This is possible because async input is gone; for details, see
333 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
334 * frame.h (struct frame): Remove async_visible and async_iconified
335 members, convert garbaged to unsigned bitfield. Adjust comments.
336 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
337 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
338 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
339 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
340 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
342 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
343 properly. Likewise for obscured.
345 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
348 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
350 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
352 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
353 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
355 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
357 * xdisp.c (message2, message2_nolog): Remove functions.
358 (message3, message3_nolog): Extract nbytes and multibyteness directly
359 from the string. Change all callers.
360 (message3_nolog): Don't set message_enable_multibyte since set_message
361 will reset it anyway.
362 (message1, message1_nolog): Use message3.
363 (vmessage): Use a stack allocated buffer rather than f->message_buf.
364 (with_echo_area_buffer): Remove last two arguments. Update all callers.
365 (set_message): Drop all but the second arg, which has to be a string.
366 (set_message_1): Simplify now that we know that a1 is NULL and the
367 second arg is a string.
368 * frame.h (struct frame): Remove `message_buf' field.
369 Use glyphs_initialized_p instead.
370 (FRAME_MESSAGE_BUF): Remove macro.
371 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
372 * lisp.h (message2, message2_nolog): Remove declarations.
373 (message3, message3_nolog): Update declarations.
374 * keyboard.c (read_char_minibuf_menu_text)
375 (read_char_minibuf_menu_width): Remove vars.
376 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
377 to correctly handle multibyte strings.
378 * frame.c (delete_frame): Don't free message_buf any more.
379 * editfns.c (message_text, message_length): Remove vars.
380 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
381 * fileio.c (auto_save_error): Use message3 instead of message2.
382 * dispnew.c (adjust_frame_message_buffer): Remove function.
384 2013-01-23 Eli Zaretskii <eliz@gnu.org>
386 * w32term.c (w32fullscreen_hook): Account correctly for the screen
387 real estate used for the tool bar and the menu bar.
389 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
391 * insdel.c (prepare_to_modify_buffer): Force redisplay if
392 hidden buffer is prepared to modification (Bug#13164).
394 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
396 * window.h (struct window): Change window_end_valid member from
397 Lisp_Object to a bitfield. Adjust comments.
398 (wset_window_end_valid): Remove.
399 * window.c (adjust_window_count): Clear window_end_valid.
400 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
401 (Fwindow_line_height, set_window_buffer, Frecenter)
402 (Fsplit_window_internal, Fdelete_other_windows_internal)
403 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
404 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
405 * xdisp.c (check_window_end, reconsider_clip_changes)
406 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
407 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
408 (find_first_unchanged_at_end_row, try_window_id): Likewise.
410 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
412 * xdisp.c (mark_window_display_accurate): Simplify the loop
413 assuming that the only one of vchild, hchild or buffer window
414 slots is non-nil. Call mark_window_display_accurate_1 for
415 the leaf windows only.
416 (mark_window_display_accurate_1): Always assume leaf window.
419 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
421 * emacs.c (Qkill_emacs_hook): Now static.
423 * fileio.c (Finsert_file_contents): Simplify.
424 Remove unnecessary assignments and tests.
426 2013-01-21 Eli Zaretskii <eliz@gnu.org>
428 * w32.c (acl_set_file): Don't test for errors unless
429 set_file_security returns FALSE. Avoids spurious errors when
432 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
434 * fileio.c (Finsert_file_contents): Revert code introduced at
435 2013-01-18 in favor of the simpler and generally better fix.
436 Save stack space by removing 'buffer' and reusing 'read_buf'
439 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
441 * lisp.h (eabs): Define unconditionally (Bug#13419).
442 The old "#if !defined (eabs)" was an unnecessary revenant of back
443 when this macro was called "abs". Document 'eabs' better.
445 2013-01-19 Glenn Morris <rgm@gnu.org>
447 * fns.c (Frandom): Doc fix.
449 2013-01-19 Eli Zaretskii <eliz@gnu.org>
451 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
452 segfault when there are lots of overlays.
454 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
455 when there are lots of overlays. See
456 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
457 for the details and a way to reproduce.
459 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
461 * fileio.c: Use O_APPEND to append.
462 This corresponds better to the natural interpretation of "append",
463 and avoids the need to open the output file twice, or to invoke
464 lseek when APPEND is neither nil nor a number.
465 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
466 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
467 file possibly twice, and lseeking to its end; this avoids the
468 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
469 at the same time: the combination is never needed and apparently
470 it doesn't work with DOS_NT.
472 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
473 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
475 Allow floating-point file offsets.
476 Problem reported by Vitalie Spinu in
477 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
478 * fileio.c (emacs_lseek): Remove.
479 (file_offset): New function.
480 (Finsert_file_contents, Fwrite_region): Use it.
482 2013-01-19 Chong Yidong <cyd@gnu.org>
484 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
485 aborting on Fsignal (Bug#13289).
487 2013-01-19 Eli Zaretskii <eliz@gnu.org>
489 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
490 set_file_security as failure due to insufficient privileges.
491 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.

494 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
496 Work around bug in CIFS and vboxsf file systems (Bug#13149).
497 The bug was observed on Ubuntu operating inside a virtual machine,
498 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
499 The workaround introduces a race condition on non-buggy hosts,
500 but it's an unlikely race and anyway there's a nearly identical
501 nearby race that can't be fixed.
502 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
504 (Fwrite_region): Test for file system time stamp bug.
505 (init_fileio): New function.
506 * lisp.h (init_fileio): Declare it.

514 Fix crash when inserting data from non-regular files. See
515 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
516 for the error description produced by valgrind.
517 * fileio.c (read_non_regular): Rename to read_contents.
518 Free Lisp_Save_Value object used to pass parameters.
519 (read_non_regular_quit): Rename to read_contents_quit.
520 (Finsert_file_contents): Redesign internal file reading loop to adjust
521 gap and end positions after each read and so help make_gap to work
522 properly. Do not signal an I/O error too early and so do not leave
523 not yet decoded characters in a buffer, which was the reason of
524 redisplay crash. Use list2 to build return value. Adjust comments.
526 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
528 Close a race when statting and reading files (Bug#13149).
529 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
530 This avoids a race if the file is renamed between stat and open.
531 This race is not the problem originally noted in Bug#13149;
532 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

957 * window.c (window_body_cols): Subtract display margins from the
958 window body width on TTYs as well. See
959 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
960 for the original report.
962 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
964 * xdisp.c (redisplay_window): Remove inner local variable
965 because the outer shadowed one has the same meaning.
966 * xterm.h (struct x_output): Remove toolbar_detached member since it's
968 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
969 (xg_create_tool_bar): Adjust users.
971 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
973 * buffer.h (BUF_COMPACT): New macro to follow the common style.
974 * buffer.c (Fget_buffer_create): Use it to set compact field of
975 struct buffer_text to avoid accessing an uninitialized value
976 when compact_buffer is called for the first time.
977 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
978 (Fset_buffer_modified_p): Use buffer_window_count to check
979 whether the buffer is displayed in some window.
980 * xdisp.c (message_dolog): Likewise.
982 2012-12-23 Eli Zaretskii <eliz@gnu.org>
984 * w32.c (acl_set_file): If setting the file security descriptor
985 fails, and the new DACL is identical to the existing one, silently
986 return success. This fixes problems for users backing up their
987 own files without having the necessary privileges for setting
988 security descriptors.
990 * w32proc.c (reader_thread): Do not index fd_info[] with negative
992 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
993 after WaitForSingleObject returns normally. This expedites reader
994 thread shutdown when delete_child triggers it.
995 (reap_subprocess): More accurate commentary for why we call
996 delete_child only when cp->fd is negative.
998 * w32.c (sys_close): Do not call delete_child on a subprocess
999 whose handle is not yet closed. Instead, set its file descriptor
1000 to a negative value, so that reap_subprocess will call
1001 delete_child on that subprocess when its SIGCHLD arrives.
1002 This avoids closing handles used for communications between sys_select
1003 and reader_thread, which doesn't give sys_select a chance to
1004 notice that the process exited and invoke the SIGCHLD handler for
1007 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1009 * nsfns.m (Fns_do_applescript): Run event loop until script has
1010 been executed (Bug#12969).
1011 (ns_run_ascript): Chech as_script for nil, set to nil after
1014 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1016 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1018 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1020 * w32term.c (w32fullscreen_hook): New function.
1021 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1023 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1025 * fileio.c (Finsert_file_contents): Doc fix.
1027 * w32proc.c (new_child, delete_child, find_child_pid): For a
1028 subprocess, consider its slot being in use as long as its process
1029 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1030 slot when a new process is started immediately after killing
1031 another one, without waiting enough time for the first process to
1032 be reaped and resources allocated for it be orderly freed.
1034 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1036 2012-12-21 Chong Yidong <cyd@gnu.org>
1038 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1040 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1042 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1044 * w32.c (get_name_and_id): Always pass NULL as the first argument
1045 of lookup_account_sid. Avoids crashes with UNC file names that
1046 refer to DFS domains, not to specific machine names. (Bug#12621)
1047 Remove now unused argument FNAME; all callers changed.
1048 (get_file_owner_and_group): Remove now unused argument FNAME; all
1051 2012-12-21 Chong Yidong <cyd@gnu.org>
1053 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1054 error for invalid chars, don't check for a nil return value.
1056 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1058 Avoid calls to CHAR_TO_BYTE if byte position is known.
1059 * editfns.c (make_buffer_string_both): Use move_gap_both.
1060 (Fbuffer_string): Use make_buffer_string_both.
1061 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1063 (buf_bytepos_to_charpos): Likewise.
1064 (charpos_to_bytepos): Remove.
1065 * fileio.c (Finsert_file_contents): Use move_gap_both.
1066 * search.c (Freplace_match): Likewise.
1067 * process.c (process_send_region): Likewise. Use convenient
1068 names for byte positions.
1069 * lisp.h (charpos_to_bytepos): Remove prototype.
1070 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1071 * insdel.c (move_gap): Likewise.
1073 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
1075 * xdisp.c (redisplay_internal): Remove now-unused local.
1077 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1079 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1080 (redisplay_internal): Don't bother selecting the frame to get the
1081 proper value of frame-local variables (bug#13225).
1083 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1085 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1086 Rename 4th argument since it may be buffer or string. Adjust comment.
1087 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1089 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1091 * coding.c (Fdetect_coding_region): Do not check start and end with
1092 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1093 (code_convert_region): Likewise.
1095 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1097 * w32.c (acl_get_file, acl_set_file): Run the file name through
1098 map_w32_filename, and resolve any symlinks in the file name, like
1100 (acl_set_file): Call revert_to_self, if any privileges were
1103 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1105 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1106 ($(BLD)/w32.$(O)): Update dependencies.
1108 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1110 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1111 propagate redisplay's scrolling (if any) to the right window.
1112 (redisplay_internal): Use ensure_selected_frame.
1113 (display_mode_lines): Complete last fix.
1114 * window.c (select_window_1): New func, extracted from select_window.
1115 (select_window): Use it.
1116 * window.h (select_window_1): Declare.
1118 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1120 Emulate Posix ACL APIs on MS-Windows.
1121 * w32.c: Include sddl.h and sys/acl.h.
1122 (SDDL_REVISION_1): Define if not already defined.
1123 (g_b_init_get_security_descriptor_dacl)
1124 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
1125 (g_b_init_is_valid_security_descriptor)
1126 (g_b_init_set_file_security): New static flags.

1138 (acl_free, acl_get_file, acl_set_file): New functions.
1140 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1142 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1144 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1145 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1146 for some of that bug's symptoms can now cause Emacs to abort.
1147 Remove the workaround.
1148 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1149 The bug that caused SIGCHLD to get lost has been fixed, and the
1150 workaround for it can now cause Emacs to abort.
1152 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1154 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1155 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1156 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1158 2012-12-16 Romain Francoise <romain@orebokech.com>
1160 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1161 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1162 and copy ACL entries of file in addition to SELinux context if set.
1163 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1165 * Makefile.in (LIBACL_LIBS): New macro.
1168 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
1170 * fileio.c (internal_delete_file): Use bool for boolean.
1172 2012-12-15 Eli Zaretskii <eliz@gnu.org>
1174 Fix bug #13079 on MS-Windows with temp files not being deleted.

1177 (register_child): First argument is now pid_t.
1178 (record_infile, record_pending_deletion): New prototypes.
1180 * w32proc.c (new_child): Initialize input_file and
1181 pending_deletion members of the child.
1182 (delete_child): Delete the child's temporary input file, if any,
1183 that is pending deletion.
1184 (register_child): First argument is now pid_t.
1185 (record_infile, record_pending_deletion): New functions.
1186 (reap_subprocess): Fix a typo in DebPrint string.
1187 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1189 * fileio.c (internal_delete_file): Return an int again: non-zero
1190 if delete-file succeeds, zero otherwise.
1192 * lisp.h (internal_delete_file): Adjust prototype.
1194 * callproc.c (Fcall_process): Don't overwrite infile with result
1196 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1197 asynchronous subprocess, record the name of the input file name,
1199 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1200 delete the file, record it as pending deletion when the subprocess
1203 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1205 * editfns.c [HAVE_PWD_H]: Include grp.h.
1207 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

1211 Fix permissions bugs with setgid directories etc. (Bug#13125)
1212 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1213 to mark it as a placeholder. The old value was often wrong.
1214 The only user of this attribute has been changed to use
1215 file-ownership-preserved-p instead, with its new group arg.
1216 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1218 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

1223 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1225 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1226 try to get accurate owner and group information from NT file
1227 security APIs. This is to make most callers of 'stat' and
1228 'lstat', which don't need that information, much faster.
1230 * dired.c (Ffile_attributes) [WINDOWSNT]:
1231 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1232 owner and group information from 'lstat'.
1234 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1236 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1237 as that confuses set-auto-coding, so insist on the head-read
1238 returning the full 1024 bytes. Let lseek compute the tail offset;
1239 less work for us. Do not ignore I/O errors when reading the tail.
1241 * xdisp.c: Minor style fixes.
1242 (init_iterator): Hoist assignment out of if-expression.
1243 (markpos_of_region): Callers now test for sign, not for -1.
1245 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>

1248 * xdisp.c (markpos_of_region): New function.
1249 (init_iterator): Do not highlight the region of zero length.
1250 (redisplay_window): Check whether the region is of non-zero length.
1251 (try_cursor_movement): Allow if the region length is zero.
1252 (try_window_reusing_current_matrix, try_window_id): Likewise.
1254 2012-12-13 Eli Zaretskii <eliz@gnu.org>
1256 * search.c (search_buffer): Check the inverse translations of each
1257 character in pattern when the buffer being searched is unibyte.
1260 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1262 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1263 files, fixing a regression from 24.2.
1264 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1266 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1268 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1269 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1270 Remove unnecessary S_ISLNK test, as (contra the comments) this
1271 function can't copy symlinks. Improve quality of error message
1272 when attempting to copy files that are neither regular files nor

1280 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1281 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1283 2012-12-12 Daniel Colascione <dancol@dancol.org>
1285 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1286 the dumped Emacs is not a sparse file, greatly improving Cygwin
1287 "make bootstrap" performance.
1289 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1291 * inotify.c (inotify_callback): Generate an Emacs event for every
1292 incoming inotify event.
1294 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1296 * xdisp.c (handle_face_prop): Fix logic of computing
1297 it->start_of_box_run_p.
1298 (append_space_for_newline): If the glyph row is R2L, reset the
1299 iterator's end_of_box_run_p flag before prepending the space glyph.
1300 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1301 iterator's start_of_box_run_p flag before prepending the stretch.
1302 (append_glyph, produce_image_glyph, append_composite_glyph)
1303 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1304 left_box_line_p and right_box_line_p flags of the glyph for R2L
1305 glyph rows. (Bug#13011)
1307 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1309 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
1310 if changed buffer is not shown in a window.
1311 * insdel.c (prepare_to_modify_buffer): Likewise.
1312 * window.c (replace_buffer_in_windows_safely): Do nothing
1313 if buffer is not shown in a window.

1319 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1320 encoded_file_name, which is what it is.
1322 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1324 Consistently use marker_position and marker_byte_position.
1325 * fringe.c (Ffringe_bitmaps_at_pos):

1333 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
1334 Replace direct access to marker fields with calls
1335 to marker_position and/or marker_byte_position.
1337 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
1339 * makefile.w32-in (SIG2STR_H): New macro.

1346 Windows file notification functionality unless WINDOWSNT.
1348 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1351 * w32fns.c (cache_system_info): Initialize the global hinst
1352 variable here so various initialization calls DTRT.
1354 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1355 (hinst): Remove unneeded extern declaration.
1356 (_start): Remove initialization of above variables; remove
1357 initialization of hinst, as cache_system_info now does that.
1359 * emacs.c (main): Call cache_system_info early in startup; we
1360 previously weren't calling it in Cygwin builds.
1362 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
1363 Teach the autoconf build system how to compile a Windows resource file
1364 and link it to Emacs.

1466 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
1468 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
1470 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
1471 DWORD_PTR, for compatibility with 64-bit builds.
1473 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
1474 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
1475 (system_process_attributes): Use SIZE_T rather than DWORD, for

1485 displayed on the left or the right margin, don't consider it as a
1486 factor in cursor positioning. (Bug#13108)
1488 2012-12-10 Martin Rudalics <rudalics@gmx.at>
1490 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
1492 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>

1497 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1499 * w32.c (unsetenv): Return 0 if the input string is too long.
1501 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1503 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1504 * alloc.c (xputenv): New function.
1505 * dbusbind.c (Fdbus_init_bus):
1507 * xterm.c (x_term_init):
1508 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

1511 (init_editfns): Initialize these two static vars.
1512 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1513 Save old TZ value on stack, if it's small.
1514 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1515 instead, use xputenv+unsetenv to set and restore TZ.
1516 (environbuf): Remove static var. All uses removed.
1517 (Fset_time_zone_rule): Do not save TZ and environ;
1518 no longer needed here.
1519 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1520 Move to inside set_time_zone_rule; they don't need file scope any more.
1521 (set_time_zone_rule): Maintain the TZ=value string separately.
1522 (syms_of_editfns): Don't initialize initial_tz;
1523 init_editfns now does it.
1524 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1525 * lisp.h (xputenv): New decl.
1527 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1529 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1531 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1533 * w32.c (unsetenv, sys_putenv): New functions.
1535 2012-12-08 Chong Yidong <cyd@gnu.org>

1538 informative (Bug#12992).
1540 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1542 Simplify get_lim_data.
1543 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1544 Remove USG and vlimit methods; no longer used these days.
1545 Add #error catchall just in case.
1547 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1548 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1549 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1550 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1551 (deleted_pid_list, Fdelete_process, create_process)
1552 (record_child_status_change, handle_child_signal, deliver_child_signal)
1553 (init_process_emacs, syms_of_process):
1554 Assume SIGCHLD is defined.
1555 (parse_signal): Remove. All uses removed.
1556 (abbr_to_signal): New static function.
1557 (Fsignal_process): Use it to convert signal names to ints.
1558 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1559 kill (getpgrp (), ...).
1560 (emacs_sigaction_init): Assume SIGCHLD is defined.
1561 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,

1565 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1566 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1568 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1570 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1571 This will cause a production Emacs to dump core instead of
1574 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1576 * frame.c (make_frame): Do not set window's buffer to t.
1577 * window.c (Fsplit_window_internal): Likewise. Previously it was
1578 used to indicate that the window is being set up. Now we use
1579 set_window_buffer for all new windows, so the condition in ...
1580 (Fset_window_buffer): ... is always true and can be removed.
1582 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1584 Convenient macro to check whether the buffer is hidden.
1585 * buffer.h (BUFFER_HIDDEN_P): New macro.
1586 * frame.c (make_frame): Use it. Adjust comment.
1587 * buffer.c (candidate_buffer): New function.
1588 (Fother_buffer, other_buffer_safely): Use it.
1590 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1592 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1593 if the child process is still running. Instead, exit the wait
1594 loop and return zero. (Bug#13086)
1596 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1598 * frame.h (x_char_width, x_char_height): Remove prototypes.

1612 * callproc.c, process.h (record_kill_process):
1613 New function, containing part of the old call_process_kill.
1614 (call_process_kill): Use it.
1615 This does not change call_process_kill's behavior.
1616 * process.c (Fdelete_process): Use record_kill_process to fix a
1617 race condition that could cause Emacs to lose track of a child.
1619 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1621 Avoid code duplication between prev_frame and next_frame.
1622 * frame.c (candidate_frame): New function. Add comment.
1623 (prev_frame, next_frame): Use it. Adjust comment.
1625 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1627 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1628 fails, signal an error instead of continuing with an empty
1630 Encode expanded temp file pattern before passing it to mkstemp or
1633 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1634 Encode the file name before passing it to dostounix_filename, in
1635 case it will downcase it (under w32-downcase-file-names).
1638 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1640 Minor call-process cleanups.
1641 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1642 at the same time as other platforms, to simplify analysis.
1643 No need for fd0_volatile since we have synch_process_fd.
1644 Avoid needless emacs_close; arg is always negative.
1646 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1648 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1651 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1653 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1654 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1655 and mouse_face_hidden members to a bitfields.
1656 * frame.h (struct frame): Remove set-but-not-used space_width member.
1657 (FRAME_SPACE_WIDTH): Remove.
1658 * nsterm.m, w32term.c, xterm.c: Adjust users.
1659 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1660 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1661 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1662 members to a bitfields.
1664 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1666 Don't let call-process be a zombie factory (Bug#12980).
1667 Fixing this bug required some cleanup of the signal-handling code.
1668 As a side effect, this change also fixes a longstanding rare race
1669 condition whereby Emacs could mistakenly kill unrelated processes,
1670 and it fixes a bug where a second C-g does not kill a recalcitrant
1671 synchronous process in GNU/Linux and similar platforms.
1672 The patch should also fix the last vestiges of Bug#9488,
1673 a bug which has mostly been fixed on the trunk by other changes.
1674 * callproc.c, process.h (synch_process_alive, synch_process_death)
1675 (synch_process_termsig, sync_process_retcode):
1676 Remove. All uses removed, to simplify analysis and so that
1677 less consing is done inside critical sections.
1678 * callproc.c (call_process_exited): Remove. All uses replaced
1679 with !synch_process_pid.
1680 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1681 These take the role of what used to be in unwind-protect arg.
1683 (block_child_signal, unblock_child_signal):
1684 New functions, to avoid races that could kill innocent-victim processes.
1685 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1686 (call_process_kill): Record killed processes as deleted, so that
1687 zombies do not clutter up the system. Do this inside a critical
1688 section, to avoid a race that would allow the clutter.
1689 (call_process_cleanup): Fix code so that the second C-g works again
1690 on common platforms such as GNU/Linux.
1691 (Fcall_process): Create the child process in a critical section,
1692 to fix a race condition. If creating an asynchronous process,
1693 record it as deleted so that zombies do not clutter up the system.
1694 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1695 light of these changes. Omit unnecessary call to emacs_close
1696 before failure, as the unwind-protect code does that.
1697 * callproc.c (call_process_cleanup):
1698 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1699 * process.c (record_deleted_pid): New function, containing
1700 code refactored out of Fdelete_process.
1701 (Fdelete_process): Use it.
1702 (process_status_retrieved): Remove. All callers changed to use
1703 child_status_change.
1704 (record_child_status_change): Remove, folding its contents into ...
1705 (handle_child_signal): ... this signal handler. Now, this
1706 function is purely a handler for SIGCHLD, and is not called after
1707 a synchronous waitpid returns; the synchronous code is moved to
1708 wait_for_termination. There is no need to worry about reaping
1709 more than one child now.
1710 * sysdep.c (get_child_status, child_status_changed): New functions.
1711 (wait_for_termination): Now takes int * status and bool
1712 interruptible arguments, too. Do not record child status change;
1713 that's now the caller's responsibility. All callers changed.
1714 Reimplement in terms of get_child_status.
1715 (wait_for_termination_1, interruptible_wait_for_termination):
1716 Remove. All callers changed to use wait_for_termination.
1717 * syswait.h: Include <stdbool.h>, for bool.
1718 (record_child_status_change, interruptible_wait_for_termination):
1720 (record_deleted_pid, child_status_changed): New decls.
1721 (wait_for_termination): Adjust to API changes noted above.
1723 * bytecode.c, lisp.h (Qbytecode): Remove.
1724 No longer needed after 2012-11-20 interactive-p changes.
1726 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1728 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1729 the scroll margin, move point outside the margin. (Bug#13055)
1731 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1733 * gtkutil.c (my_log_handler): New function.
1734 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1736 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1738 * lisp.h (modify_region): Rename to...
1739 (modify_region_1): ...new prototype.
1740 * textprop.c (modify_region): Now static. Adjust users.
1741 * insdel.c (modify_region): Rename to...
1742 (modify_region_1): ...new function to work with current buffer.
1743 Adjust comment and users. Use true and false for booleans.
1745 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1747 * alloc.c (free_save_value): New function.
1748 (safe_alloca_unwind): Use it.
1749 * lisp.h (free_save_value): New prototype.
1750 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1752 (save_excursion_restore): Adjust to match saved data structure.
1753 Use free_save_value to offload some work from GC. Drop obsolete
1756 2012-12-03 Chong Yidong <cyd@gnu.org>
1758 * fileio.c (Vauto_save_list_file_name): Doc fix.
1760 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1762 * w32fns.c: Remove prototype of atof.
1763 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1765 (file_dialog_callback): Make it UINT_PTR.
1767 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1770 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1771 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1774 2012-12-03 Glenn Morris <rgm@gnu.org>
1776 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1778 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1780 Fix xpalloc confusion after memory is exhausted.
1781 * alloc.c (xpalloc): Comment fix.
1782 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1783 and signals an error, do not clear charset_table_size, as
1784 charset_table is still valid.
1785 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1787 Use execve to avoid need to munge environ (Bug#13054).
1788 * callproc.c (Fcall_process):
1789 * process.c (create_process):
1790 Don't save and restore environ; no longer needed.
1791 * callproc.c (child_setup):
1792 Use execve, not execvp, to preserve environ.
1794 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1796 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1798 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1800 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1801 display for sliced images (Bug#10500).
1803 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1805 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1807 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1808 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1810 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1812 * xdisp.c (window_outdated): Remove eassert since it hits
1813 some suspicious corner cases (see Bug#13007 and Bug#13012).
1814 (mode_line_update_needed): New function.
1815 (redisplay_internal, redisplay_window): Use it.
1816 (ensure_selected_frame): New function.
1817 (redisplay_internal, unwind_redisplay): Use it.
1818 (redisplay_internal): Move comment about buffer_shared...
1819 (buffer_shared_and_changed): ...near to its real use.
1821 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1823 * callproc.c (Fcall_process): Don't misreport vfork failure.
1825 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1827 * callproc.c (Fcall_process): Fix vfork portability problems.
1828 Do not assume that fd[0], count, filefd, and save_environ survive
1829 vfork. Fix bug whereby wrong errno value could be reported for
1830 pipe failure. Some minor cleanups, too, as follows. Move buf and
1831 bufsize to the context where they're needed. Change new_argv to
1832 be of type char **, as this is more convenient and avoids casts.
1833 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1834 Now local constants, not macros.
1836 2012-11-18 Kenichi Handa <handa@gnu.org>
1838 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1839 for the variable "f".
1841 2012-11-13 Kenichi Handa <handa@gnu.org>
1843 * font.c (font_unparse_xlfd): Exclude special characters from the
1844 generating XLFD name.
1846 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1848 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
1849 * dired.c (stat_uname, stat_gname):
1850 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1852 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1854 Assume EAGAIN and EINTR are defined.
1856 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1857 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
1858 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
1859 * lread.c (readbyte_from_file): Assume EINTR is defined.
1860 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1861 Assume EIO and EAGAIN are defined.
1862 * unexcoff.c (write_segment): Assume EFAULT is defined.
1864 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1866 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1869 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1870 highlighting on the frame was cleared. Prevents assertion
1871 violations when repeatedly clicking on the "Top" link of the
1872 "bread-crumbs" in Info buffers.
1874 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
1876 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
1878 2012-11-24 Ken Brown <kbrown@cornell.edu>
1880 * keyboard.c (HAVE_MOUSE):
1881 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1882 were always defined.
1884 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1886 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1887 between bpos_covered and bpos_max. This fixes cursor display when
1888 several display strings follow each other.
1890 * .gdbinit (pgx): If the glyph's object is a string, display the
1891 pointer to string data, rather than the value of the string object
1892 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1894 * indent.c (Fvertical_motion): If the starting position is covered
1895 by a display string, return to one position before that, to avoid
1896 overshooting it inside move_it_to. (Bug#12930)
1898 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1900 * frame.h (struct frame): Remove display_preempted member
1901 since all users are dead long ago.
1902 * nsterm.h (struct x_output): Use the only dummy member.
1903 * w32menu.c (pending_menu_activation): Remove since not
1905 (set_frame_menubar): Adjust user.
1906 * w32term.h (struct x_output): Drop outdated #if 0 code.
1907 (struct w32_output): Use bitfields for explicit_parent,
1908 asked_for_visible and menubar_active members.
1909 Drop unused pending_menu_activation member.
1910 * xterm.h (struct x_output): Drop outdated #if 0 code.
1911 Use bitfields for explicit_parent, asked_for_visible,
1912 has_been_visible and net_wm_state_hidden_seen members.
1914 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1916 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1917 of a literal "/". (Bug#12955)
1918 (gl-stamp): Invoke fc.exe directly, not through cmd.
1920 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1922 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1923 * dired.c: Assume HAVE_DIRENT_H.
1924 (NAMLEN): Remove, replacing with ...
1925 (dirent_namelen): New function. All uses changed. Use the GNU macro
1926 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1927 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1928 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1929 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1931 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1932 * ndir.h: Rename to ../nt/inc/dirent.h.
1933 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1934 Do not include <dirent.h>; no longer needed.
1935 * w32.c: Include <dirent.h> rather than "ndir.h".

1939 * xftfont.c (xftfont_open): Remove duplicate assignment.
1941 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1943 * alloc.c (Fgarbage_collect): Unblock input after clearing
1944 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1945 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1946 * msdos.c (IT_frame_up_to_date): Use it here...
1947 * w32term.c (w32_frame_up_to_date): ...here...
1948 * xterm.c (XTframe_up_to_date): ...and here...
1949 * nsterm.m (ns_frame_up_to_date): ...but not here.
1950 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1952 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1953 Do not check whether GC is in progress.
1955 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1957 * xdisp.c (window_buffer_changed): New function.
1958 (update_menu_bar, update_tool_bar): Use it to
1959 simplify large 'if' statements.
1960 (redisplay_internal): Generalize commonly used
1961 'tail' and 'frame' local variables.
1963 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1965 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1966 with Windows system header.
1968 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1970 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1971 * alloc.c: Assume unistd.h exists.
1972 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1973 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1974 (getwd) [USG]: Remove; no longer needed.
1975 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1976 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1977 * w32.h (getcwd): Remove decl.
1979 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1981 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1982 Make it set selected_window as well.
1983 (update_tool_bar): Use it.
1985 2012-11-21 Ken Brown <kbrown@cornell.edu>
1987 * emacs.c (main): Set the G_SLICE environment variable for all
1988 Cygwin builds, not just GTK builds. See
1989 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1991 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1993 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1994 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1995 Define for the MSVC compiler.
1997 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1999 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2000 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2001 dostounix_filename. Prevents crashes down the road, because
2002 dostounix_filename assumes it gets a unibyte string.
2003 Reported by Michel de Ruiter <michel@sentient.nl>, see
2004 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2006 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

2010 * lread.c (init_obarray): Set `function' fields to Qnil.
2011 * eval.c (Fcommandp): Ignore Qunbound.
2012 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2013 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2014 Test NILP rather than Qunbound.
2015 (Ffmakunbound): Set to Qnil.
2016 (Fsymbol_function): Never signal an error.
2017 (Finteractive_form): Ignore Qunbound.
2019 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2021 * eval.c (interactive_p): Remove no-longer-used decl.
2023 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2025 * xdisp.c (buffer_shared): Adjust comment.
2026 (buffer_shared_and_changed): New function.
2027 (prepare_menu_bars, redisplay_internal): Use it to
2028 decide whether all windows or frames should be updated.
2029 (window_outdated): New function.
2030 (text_outside_line_unchanged_p, redisplay_window): Use it.
2031 (redisplay_internal): Likewise. Fix indentation.
2033 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2035 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2036 (syms_of_eval): Remove corresponding defsubr.
2037 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2039 2012-11-19 Daniel Colascione <dancol@dancol.org>
2041 * w32fns.c (Fx_file_dialog):
2042 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2043 cygwin_convert_file_name*.
2045 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2046 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2048 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2050 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2052 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2054 * w32select.c: Include w32common.h before w32term.h, so that
2055 windows.h gets included before w32term.h uses some of its
2056 features, see below.
2058 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2060 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2062 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2064 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2066 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2067 (ns_select): Return at once if events are held (Bug#12834).
2069 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2071 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2072 Needed following 2012-10-20 change. (Bug#12902)
2074 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2076 * w32proc.c (waitpid): Remove unused label get_result.
2078 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2080 * makefile.w32-in (SYSWAIT_H): New macro.
2081 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2082 ($(BLD)/sysdep.$(O)): Update dependencies.
2084 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2086 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2087 * callproc.c (relocate_fd): Assume F_DUPFD.
2088 * emacs.c, term.c (O_RDWR): Remove.
2089 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2090 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2091 * nsterm.m: Assume <fcntl.h> exists.
2092 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2093 (create_pty, Fmake_network_process, server_accept_connection)
2094 (wait_reading_process_output, init_process_emacs):
2096 (wait_reading_process_output): Put in a special case for WINDOWSNT
2097 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2098 It's not clear this is needed, but it's a more-conservative change.
2099 (create_process): Assume FD_CLOEXEC.
2100 (create_process, create_pty): Assume O_NOCTTY.
2101 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2102 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2103 Omit if not DOS_NT, since F_GETFL is not defined there.
2104 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2105 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2107 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2108 lack it, since gnulib guarantees this.
2109 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2111 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2113 * w32.c (faccessat): Pretend that directories have the execute bit
2114 set. Emacs expects that, e.g., in files.el:cd-absolute.
2116 * w32proc.c (create_child): Don't clip the PID of the child
2117 process to fit into an Emacs integer, as this is no longer a
2119 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2120 reaping only the process specified by PID argument, if that is
2121 positive. Use PID instead of dead_child to know which process to
2122 reap. Wait for the child to die only if WNOHANG is not in
2124 (sys_select): Don't set dead_child.
2126 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2127 as it is no longer needed.
2129 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2131 (record_child_status_change): Remove the setting of
2132 record_at_most_one_child for the !WNOHANG case.
2134 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2136 Fix problems in ns port found by static checking.
2137 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2138 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2139 not to process group.
2140 (ns_select): Use emacs_write, not write, as that's more robust
2141 in the presence of signals.
2142 (fd_handler:): Check for read errors.
2144 2012-11-16 Glenn Morris <rgm@gnu.org>
2146 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2148 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2150 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2152 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2154 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2155 use the same value of thread handle.
2156 (start_timer_thread): If the timer thread exited (due to error),
2157 clean up by closing the two handles it used. Duplicate the caller
2158 thread's handle here, so it gets duplicated only once, when
2159 launching the timer thread. Set priority of the timer thread, not
2161 (getitimer): Don't duplicate the caller thread's handle here.
2164 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2166 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2169 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2171 Remove no-longer-used pty_max_bytes variable.
2172 * process.c (pty_max_bytes): Remove; unused.
2173 (send_process): Do not set it.
2175 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2177 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2178 Update dependencies.
2180 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2182 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2183 This follows up on the 2012-09-29 patch that removed indirection
2184 for the 'function' field. Reported by Sergey Vinokurov in
2185 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2187 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2189 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2190 different name, as the MS runtime does not have such a function,
2191 and probably never will.) All callers changed. Ignore DIRFD
2192 value if PATH is an absolute file name, to match Posix spec
2193 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2196 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2198 * xdisp.c (echo_area_display, redisplay_internal):
2199 Omit redundant check whether frame_garbaged is set.
2201 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2203 Use faccessat, not access, when checking file permissions (Bug#12632).
2204 This fixes a bug that has been present in Emacs since its creation.
2205 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2206 which must set some sort of record. (Torek's bug report was against
2207 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2208 same common flaw.) See Torek's Usenet posting
2209 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2210 Posted: Fri Apr 8 14:18:56 1983.
2211 * Makefile.in (LIB_EACCESS): New macro.
2213 * callproc.c (init_callproc):
2214 * charset.c (init_charset):
2215 * fileio.c (check_existing, check_executable, check_writable)
2217 * lread.c (openp, load_path_check):
2218 * process.c (allocate_pty):
2220 Use effective UID when checking permissions, not real UID.
2221 * callproc.c (init_callproc):
2222 * charset.c (init_charset):
2223 * lread.c (load_path_check, init_lread):
2224 Test whether directories are accessible, not merely whether they exist.
2225 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2226 * fileio.c (check_existing, check_executable, check_writable)
2228 Use symbolic names instead of integers for the flags, as they're
2230 (check_writable): New arg AMODE. All uses changed.
2231 Set errno on failure.
2232 (Ffile_readable_p): Use faccessat, not stat + open + close.
2233 (Ffile_writable_p): No need to call check_existing + check_writable.
2234 Just call check_writable and then look at errno. This saves a syscall.
2235 dir should never be nil; replace an unnecessary runtime check
2236 with an eassert. When checking the parent directory of a nonexistent
2237 file, check that the directory is searchable as well as writable, as
2238 we can't create files in unsearchable directories.
2239 (file_directory_p): New function, which uses 'stat' on most platforms
2240 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2241 (Ffile_directory_p, Fset_file_times): Use it.
2242 (file_accessible_directory_p): New function, which uses a single
2243 syscall for efficiency.
2244 (Ffile_accessible_directory_p): Use it.
2245 * xrdb.c (file_p): Use file_directory_p.
2246 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2247 * lread.c (openp): When opening a file, use fstat rather than
2248 stat, as that avoids a permissions race. When not opening a file,
2249 use file_directory_p rather than stat.
2250 (dir_warning): First arg is now a usage string, not a format.
2251 Use errno. All uses changed.
2252 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2253 that merely introduced a race.
2254 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2255 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2256 and similarly for the other O_* flags.
2257 * w32.c (sys_faccessat): Rename from sys_access and switch to
2258 faccessat's API. All uses changed.
2259 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2260 (magic_db): Rename from magic_file_p.
2261 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2262 char *, so that we don't have to test for file existence
2263 separately from opening the file for reading. This removes a race
2264 fixes a permission-checking problem, and simplifies the code.
2266 (file_p): Remove; no longer needed.
2268 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2270 Omit glyphs initialization at startup.
2271 * dispnew.c (glyphs_initialized_initially_p): Remove.
2272 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2273 (Fredraw_frame): Move actual code from here...
2274 (redraw_frame): ...to here. Add eassert. Adjust comment.
2275 (Fredraw_display): Use redraw_frame.
2276 * xdisp.c (clear_garbaged_frames): Likewise.
2278 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2280 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2281 passed to pint2str and pint2hrstr to be at most the size of the
2282 frame's decode_mode_spec_buffer. This avoids crashes with very
2283 large values of FIELD_WIDTH argument to decode_mode_spec.
2286 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2288 Fix a race with verify-visited-file-modtime (Bug#12863).
2289 Since at least 1991 Emacs has ignored an mtime difference of no
2290 more than one second, but my guess is that this was to work around
2291 file system bugs that were fixed long ago. Since the race is
2292 causing problems now, let's remove that code.
2293 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2294 whose time stamp is off by no more than a second. Insist that the
2295 file time stamps match exactly.
2297 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2299 * frame.h (struct frame): Convert external_tool_bar member to
2300 1-bit unsigned bitfield.
2301 * termhooks.h (struct terminal): Remove mouse_moved member since
2302 all users are long dead. Adjust comment on mouse_position_hook.
2304 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2306 Simplify by using FOR_EACH_FRAME here and there.
2307 * frame.c (next_frame, prev_frame, other_visible_frames)
2308 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2309 * w32term.c (x_window_to_scroll_bar): Likewise.
2310 * window.c (window_list): Likewise.
2311 * xdisp.c (x_consider_frame_title): Likewise.
2312 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2313 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2314 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2315 * xmenu.c (menubar_id_to_frame): Likewise.
2316 * xselect.c (frame_for_x_selection): Likewise.
2317 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2318 (x_window_to_menu_bar): Likewise.
2319 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2321 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2323 * data.c (Qdefalias_fset_function): Now static.
2325 Another tweak to vectorlike_header change.
2326 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2327 Remove, and replace all uses with ...
2328 (next_in_free_list, set_next_in_free_list):
2329 New functions, which respect C's aliasing rules better.
2331 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2333 * window.c (list4i): Rename from 'quad'. All uses changed.
2334 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2336 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2338 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2339 warning about mixing declarations and code in ISO C90.
2341 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2343 * window.c (Fsplit_window_internal): Set combination limit of
2344 new parent window to t iff Vwindow_combination_limit is t;

2350 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2351 amount when the scroll margins are too large. When scrolling
2352 backwards in the buffer, give up if cannot reach point or the
2353 scroll margin within a reasonable number of screen lines.
2354 Fixes point position in window under scroll-up/down-aggressively when
2355 point is positioned many lines beyond the window top/bottom.
2358 * ralloc.c (relinquish): If real_morecore fails to return memory
2359 to the system, don't crash; instead, leave the last heap
2360 unchanged and return. (Bug#12774)

2383 Fix recently introduced crash on MS-Windows (Bug#12839).
2384 * w32term.h (struct scroll_bar): Use convenient header.
2385 (SCROLL_BAR_VEC_SIZE): Remove.
2386 * w32term.c (x_scroll_bar_create): Use VECSIZE.

2390 Tweak last vectorlike_header change.
2391 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2392 vectorlike object on the free list. This is introduced to avoid
2393 some (but not all) pointer casting and aliasing problems, see
2394 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2395 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

2399 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2401 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2402 been removed, so remove them here also.

2406 * doc.c (Fdocumentation): Handle new property
2407 dynamic-docstring-function to replace the old ad-advice-info.

2423 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2424 * lisp.h (sxhash_combine): New inline function, with the contents
2425 of the old SXHASH_COMBINE.
2426 * profiler.c (hashfn_profiler): Use it, instead of having a
2427 special hash function containing a comparison that always yields 1.
2429 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2431 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2432 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2433 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2436 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2438 * image.c (xpm_make_color_table_h): Fix compiler error because
2439 make_hash_table changed.
2441 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2443 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2445 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2447 Use ad-hoc comparison function for the profiler's hash-tables.
2448 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2449 (make_log): Use them.
2450 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2451 call Fequal any more.

2460 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2461 (hash_lookup, hash_remove_from_table): Move assertion checking of
2462 hashfn result here. Check hash-equality before calling cmpfn.

2464 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
2465 (syms_of_fns): Initialize them.

2474 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2475 value of w32-scroll-lock-modifier is neither nil nor one of the
2476 known key modifiers. (Bug#12806)
2478 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2480 Shrink struct vectorlike_header to the only size field.
2481 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2483 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2484 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2485 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2486 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2487 information from the vector header. Adjust comment.

2502 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2503 (large_vectors): Change type to struct large_vector.
2504 (allocate_vector_from_block): Simplify.
2505 (PSEUDOVECTOR_NBYTES): Replace with...
2506 (vector_nbytes): ...new function. Adjust users.
2507 (sweep_vectors): Adjust processing of large vectors.
2508 (allocate_vectorlike): Likewise.
2509 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2510 Add easserts. Adjust XSETPVECTYPESIZE usage.
2511 (allocate_buffer): Use BUFFER_PVEC_INIT.
2512 (live_vector_p): Adjust to match large vector.
2513 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2514 * buffer.h (struct buffer): Add next member.
2515 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2517 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2518 * fns.c (internal_equal): Adjust to match enum pvec_type change.

2523 (xvecsize): New command.
2525 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2527 * keyboard.c (event_to_kboard): Do not dereference
2528 frame_or_window field of SELECTION_REQUEST_EVENT
2529 and SELECTION_CLEAR_EVENT events (Bug#12814).
2530 * xterm.h (struct selection_input_event): Adjust comment.
2532 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2534 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2535 such as Scroll Lock, if the respective keys are treated as
2536 function keys, not as modifiers. This avoids destroying non-ASCII
2537 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2539 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2541 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2543 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2545 Restore some duplicate definitions (Bug#12814).
2546 This undoes part of the 2012-11-03 changes. Some people build
2547 with plain -g rather than with -g3, and they need the duplicate
2548 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2549 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2550 Define as macros, as well as as enums or as constants.
2552 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2554 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2555 to keypad keys (Bug#12816).
2557 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2559 Minor adjustments of recently-changed frame functions.
2560 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2561 known to be a frame (we're in the FRAMEP branch).
2562 * lisp.h (Qframep): Remove decl. frame.h declares this.
2563 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2564 since they're meant for Lisp fixnum values.
2566 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2568 * window.c (Fwindow_combination_limit): Revert to the only
2569 required argument and adjust docstring as suggested in
2570 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2571 by Martin Rudalics <rudalics@gmx.at>.
2573 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2575 Widely used frame validity and checking functions.
2576 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2577 * frame.c (decode_live_frame, decode_any_frame): New functions.
2578 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2579 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2580 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2581 (Fframe_pointer_visible_p): Use decode_any_frame.
2582 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2583 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2584 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2585 (Fframe_focus): Likewise. Allow zero number of arguments.
2587 (frame_buffer_list, frame_buffer_predicate): Remove.
2588 * lisp.h (frame_buffer_predicate): Remove prototype.
2589 * buffer.c (Fother_buffer): Use decode_any_frame.
2590 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2591 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2592 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2593 (Fclose_font, Ffont_info): Use decode_live_frame.
2594 * fontset.c (check_fontset_name): Likewise.
2595 * terminal.c (Fframe_terminal): Likewise.
2596 * w32fns.c (check_x_frame): Likewise.
2597 * window.c (Fminibuffer_window, Fwindow_at)
2598 (Fcurrent_window_configuration): Likewise.
2599 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2600 Likewise. Allow zero number of arguments. Adjust docstring.
2601 * dispnew.c (Fredraw_frame): Likewise.
2602 * xfaces.c (frame_or_selected_frame): Remove.
2603 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2604 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2605 (Fframe_face_alist): Use decode_live_frame.
2606 * xfns.c (check_x_frame): Likewise.
2608 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2610 * window.c (quad): New function.
2611 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2612 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2613 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2614 (Fwindow_line_height): Use it.
2615 (Fwindow_fringes): Use list3.
2616 (Fwindow_scroll_bars): Use list4.
2617 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2618 (Fwindow_combination_limit): Allow zero number of arguments.
2620 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2622 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2624 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2625 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2626 file descriptor 2 for standard error. (Bug#12805)
2628 2012-11-05 Chong Yidong <cyd@gnu.org>
2630 * process.c (wait_reading_process_output): Revert previous change.
2632 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2634 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2635 This removes code that has been obsolete since around 1990.
2636 * callproc.c (Fcall_process):
2638 * process.c (create_process):
2639 * term.c (dissociate_if_controlling_tty):
2640 Assume setsid exists.
2641 * callproc.c (child_setup): Assume setpgid exists and behaves as
2642 per POSIX.1-1988 or later.
2643 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2644 * emacs.c (shut_down_emacs):
2645 * sysdep.c (sys_suspend, init_foreground_group):
2646 Assume getpgrp behaves as per POSIX.1-1998 or later.
2647 * msdos.c (setpgrp): Remove.
2648 (tcgetpgrp, setpgid, setsid): New functions.
2649 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2650 * term.c (no_controlling_tty): Remove; unused.
2651 * w32proc.c (setpgrp): Remove.
2652 (setsid, tcgetpgrp): New functions.
2654 Simplify by assuming __fpending.
2655 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2656 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2657 Do not assume that __fpending's result fits in int.
2659 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2661 Remove EMACS_OUTQSIZE+sleep hack.
2662 * dispnew.c (update_frame_1): Remove hack for terminals slower
2663 than 2400 bps, which throttled Emacs by having it sleep.
2664 This code hasn't worked since at least 2007, when the multi-tty stuff
2665 was added, and anyway those old terminals are long dead.
2666 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2667 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2669 Fix data-loss with --version (Bug#9574).
2670 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2671 as we can't assume that emacs_strerror is initialized, and strerror
2672 is good enough here.
2673 (main): Invoke atexit earlier, to catch earlier instances of
2674 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2676 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2678 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2679 (keyDown): Remap keypad keys to X11 virtual key codes.
2681 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2683 Fix data-loss with --batch (Bug#9574).
2684 * emacs.c: Include <close-stream.h>.
2685 (close_output_streams): New function.
2686 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2687 and handles errors appropriately.
2688 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2691 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2692 The symptom is a diagnostic "GLib-WARNING **: In call to
2693 g_spawn_sync(), exit status of a child process was requested but
2694 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2695 waitpid(), so exit status can't be returned." The diagnostic
2696 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2697 The real bug is a race condition between Emacs and glib: Emacs
2698 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2699 so that glib can't find it. Work around the bug by invoking
2700 waitpid only on subprocesses that Emacs itself creates.
2701 * process.c (create_process, record_child_status_change):
2702 Don't use special value -1 in pid field, as the caller now must
2703 know the pid rather than having the callee infer it.
2704 The inference was sometimes incorrect anyway, due to another race.
2705 (create_process): Set new 'alive' member if child is created.
2706 (process_status_retrieved): New function.
2707 (record_child_status_change): Use it.
2708 Accept negative 1st argument, which means to wait for the
2709 processes that Emacs already knows about. Move special-case code
2710 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2711 processes that have already been waited for, by testing and
2712 clearing new 'alive' member.
2713 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2714 now does this internally.
2715 (handle_child_signal): Let record_child_status_change do all
2716 the work, since we do not want to reap all exited child processes,
2717 only the child processes that Emacs itself created.
2718 * process.h (Lisp_Process): New boolean member 'alive'.
2720 Omit duplicate definitions no longer needed with gcc -g3.
2721 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2722 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2723 Define only as macros. There's no longer any need to also define
2724 these symbols as enums or as constants, since we now assume
2725 gcc -g3 when debugging.
2727 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2729 * lisp.mk: Adjust comments to the fact that term/internal is now
2730 loaded from loadup.el.
2732 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2733 (msdos_fatal_signal): New function.
2734 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2737 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2738 for GCC versions before 4.
2739 (emacs_raise): Define to call msdos_fatal_signal.
2741 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2742 iterator when starting in the middle of a display or overlay
2745 2012-11-03 Chong Yidong <cyd@gnu.org>
2747 * process.c (wait_reading_process_output): Clean up the last
2750 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2752 * process.c (wait_reading_process_output): Avoid a race condition
2753 with SIGIO delivery (Bug#11536).
2755 2012-11-03 Chong Yidong <cyd@gnu.org>
2757 * buffer.c (cursor_type): Untabify docstring.
2759 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2761 * frame.h (struct frame): Drop can_have_scroll_bars member
2762 which is meaningless for a long time. Adjust comments.
2763 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2764 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2766 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2768 * window.c (decode_next_window_args): Update window arg after
2769 calling decode_live_window and so fix crash reported at
2770 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2771 by Juanma Barranquero <lekktu@gmail.com>.
2772 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2773 * font.c (Ffont_at): Likewise.
2775 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2777 * widget.c (resize_cb): New function.
2778 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).

2791 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2793 Window-related stuff cleanup here and there.
2794 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2795 Use decode_any_window.

2803 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2804 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2807 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2809 Remove pad from struct input_event.
2810 * termhooks.h (struct input_event): Remove padding field.
2812 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2813 member is never cons for a long time. Adjust comment.
2814 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2815 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2816 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2817 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2819 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2821 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2823 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2825 Fix crash when using Emacs as commit editor for git (Bug#12697).
2826 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2827 and it is configured in conf_post.h.
2828 (Fcall_process): Don't invoke both setsid and setpgid; the former
2829 is enough, if it exists.
2830 * callproc.c (Fcall_process, child_setup):
2831 * process.c (create_process): Use setpgid.
2832 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2834 * dispnew.c (init_display): Initialize the foreground group
2835 if we are running a tty display.
2836 * emacs.c (main): Do not worry about setpgrp; init_display does it now.

2838 * sysdep.c (inherited_pgroup): New static var.
2839 (init_foreground_group, tcsetpgrp_without_stopping)

2841 (init_sys_modes): Narrow foreground group.
2842 (reset_sys_modes): Widen foreground group.
2844 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2846 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2848 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2850 * minibuf.c (read_minibuf): Restore current buffer since
2851 choose_minibuf_frame calling Fset_frame_selected_window may
2852 change it (Bug#12766).

2860 * font.c (Ffont_at): If WINDOW is specified and it is not
2861 displaying the current buffer, signal an error.
2863 2012-10-29 Daniel Colascione <dancol@dancol.org>
2865 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2866 In preparation for fixing bug#12739, move these functions from
2869 * coding.h, coding.c: ... to here, and compile them only when
2870 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2871 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2873 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2875 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2876 (timer_loop, getitimer, setitimer): Use it instead of
2877 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2879 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2882 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>

2887 (ns_select): Initialize t from last_appdefined_event_data instead
2888 of [last_appdefined_event data1].
2889 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2890 remove last_appdefined_event (Bug#12698).
2892 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2894 * frame.c (x_set_font): Catch internal error.
2896 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2898 Avoid overflow in w32 implementation of interval timers.
2899 When possible, for ITIMER_PROF count only times the main thread
2901 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2902 'volatile ULONGLONG' types. All the other data which was
2903 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2904 (GetThreadTimes_Proc): New typedef.
2905 (w32_get_timer_time): New function, returns a suitable time value
2907 (timer_loop): Enter critical section when accessing ULONGLONG
2908 values of the itimer_data struct, as these accesses are no longer
2909 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2910 Remove unused variable.
2911 (init_timers): Initialize s_pfn_Get_Thread_Times.
2912 (start_timer_thread): Don't assign itimer->caller_thread here.

2919 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2920 mouse movement events if the menu bar is active. This avoids
2921 producing a busy "hour-glass" cursor by Windows if the mouse
2922 pointer is positioned over a tooltip shown for some menu item.
2924 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2926 Don't assume process IDs fit in int.
2927 * emacs.c (shut_down_emacs) [!DOS_NT]:
2928 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2929 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2930 Use pid_t, not int, to store process IDs, as 'int'
2931 is not wide enough on a few platforms (e.g., AIX and IRIX).
2933 2012-10-23 Kenichi Handa <handa@gnu.org>
2935 The following change is to make face-font-rescale-alist work
2936 correctly for non-ASCII fonts.
2938 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2939 (font_open_for_lface): Handle Vface_font_rescale_alist.

2954 2012-10-21 Glenn Morris <rgm@gnu.org>
2956 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2958 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>

2961 * frame.c (Fmouse_position, Fmouse_pixel_position):
2962 * xdisp.c (produce_stretch_glyph):
2963 Declare local vars only when they're needed.
2964 This is clearer and avoids a warning on OpenBSD about unused vars.

2966 This is safer, and avoids OpenBSD warnings about unused vars.
2967 * keyboard.c (record_menu_key): Remove unnecessary decl.
2968 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2969 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2970 as our definition clashes with OpenBSD's.
2971 * xfaces.c (load_face_colors, check_lface_attrs)
2972 (get_lface_attributes_no_remap, get_lface_attributes)
2973 (lface_fully_specified_p, x_supports_face_attributes_p)
2974 (tty_supports_face_attributes_p, face_fontset, realize_face)
2975 (realize_x_face, realize_tty_face):
2976 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2977 merely Lisp_Object *. This is more informative and avoids
2978 a warning on OpenBSD about accessing beyond an object's size.
2980 2012-10-20 Chong Yidong <cyd@gnu.org>
2982 * lread.c (Fload): Doc fix (Bug#12592).

3008 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3009 (staticpro): If we run out of staticpro slots, die with an
3010 informative error instead of just calling emacs_abort.
3012 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3014 Fix two flaws reported by Dmitry Antipov.

3265 * keyboard.c (timers_run, swallow_events)
3266 (detect_input_pending_run_timers):
3267 * process.c (wait_reading_process_output):
3268 Use unsigned for counter where wraparound-on-overflow is desired,
3269 since unsigned is guaranteed to have that behavior and signed is not.
3270 (read_char): Use ptrdiff_t for string length.
3271 (get_input_pending): Remove first argument, since it was always
3272 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3273 and behave as if it had that value. Return new value of
3274 input_pending. All callers changed.
3275 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3276 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
3278 * keymap.c (push_key_description): Omit last arg, which was always 1.
3279 All callers changed.
3281 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

3292 initializer for PVEC_NORMAL_VECTOR.
3294 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3296 Clean out old termopts cruft.
3297 * termopts.h (flow_control, meta_key): Remove unused decls.
3298 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
3299 Don't include termopts.h.
3301 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3303 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3305 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3307 * commands.h (immediate_quit): Remove duplicate decl.
3309 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3311 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
3313 (nsfont_open): Remove setting of Vfonts_in_cache.
3314 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3316 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3318 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3319 match what GetLastError returns. Explain why the function is
3322 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3323 'is_tooltip_frame', to avoid confusion with its global namesake.
3325 2012-10-08 Daniel Colascione <dancol@dancol.org>
3327 * xdisp.c (start_hourglass): Call w32_note_current_window when
3328 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3329 build that caused Emacs to display the hourglass cursor forever.
3331 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3332 which is broken under remote desktop, calculate the number of
3333 colors available for a display based on the display's number of
3334 planes and number of bits per pixel per plane. (bug#10397).
3336 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3338 * nsfont.m (Vfonts_in_cache): New variable.
3339 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3340 are used. Add cached fonts to Vfonts_in_cache.
3341 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3343 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3345 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3347 (FONT_H): Define after FRAME_H.
3348 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3349 Update dependencies.
3351 * w32term.c: Remove leftover declaration of keyboard_codepage.
3353 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3355 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3356 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3357 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3358 (GLOBAL_SOURCES): Add cygw32.c.

3361 ($(BLD)/w32console.$(O)):
3362 ($(BLD)/w32fns.$(O)):
3363 ($(BLD)/w32heap.$(O)):
3364 ($(BLD)/w32menu.$(O)):
3365 ($(BLD)/w32proc.$(O)): Add w32common.h.
3367 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3369 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3371 2012-10-08 Daniel Colascione <dancol@dancol.org>
3373 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3374 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3375 accidental message numbering hole. Change other messages to
3378 * w32select.h (HAVE_W32SELECT): Remove.
3380 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3381 w32common.h instead of w32heap.h.
3383 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3384 (get_allocation_unit, get_processor_type, get_w32_major_version)

3387 (OS_NT, os_subtype, cache_system_info): Move declarations to
3390 * w32heap.c: Include w32common.h.
3391 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3392 (w32_minor_version, w32_build_number, w32_subtype):
3393 Remove duplicate definitions.
3395 * w32fns.c: Include w32common.h; include w32heap.h only in
3398 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3399 Use `report_file_error' instead of `error' in order to better
3400 inform users of what went wrong. Increase NTGUI_UNICODE file
3401 dialog box file name length to 32k, the maximum allowed by the NT
3404 * w32common.h: New file.
3405 (ROUND_UP, ROUND_DOWN, get_page_size)
3406 (get_allocation_unit, get_processor_type, get_w32_major_version)
3407 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3408 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3409 (OS_NT, os_subtype, cache_system_info): Move here.
3411 * unexw32.c, unexcw.c: Include w32common.h.
3413 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3414 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3415 to call syms_of_w32select.
3417 * cygw32.h: Remove obsolete EXFUN declarations.
3419 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3421 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3422 of w32inevt.o from SOME_MACHINE_OBJECTS.
3424 2012-10-08 Daniel Colascione <dancol@dancol.org>
3426 * image.c: Permanent fix for JPEG compilation issue --- limit
3427 jpeglib `boolean' redefinition to Cygwin builds.
3429 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3431 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3433 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3436 2012-10-08 Daniel Colascione <dancol@dancol.org>
3438 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3439 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3440 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3441 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3442 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3443 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3444 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3445 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3446 now a supported configuration.
3448 * Makefile.in: consolidate image variables into LIBIMAGE; add
3449 W32_OBJ and W32_LIBS. Compile new files.
3452 (_DebPrint) declare tracing facility for W32 debugging. We need
3453 to unify tracing later.
3455 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3456 unconditional use of W32 Unicode functions. Cygwin runs only on
3457 100% Unicode operating systems.
3459 * cygw32.c: New file. Define Cygwin-specific facilities.
3460 (Fcygwin_convert_path_to_windows)
3461 (Fcygwin_convert_path_from_windows): New user functions for
3462 accessing Cygwin path-munging routines.
3464 * cygw32.h: New file.
3465 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3466 UTF-16LE strings temporarily inside non-Lisp-visible string
3469 (w32_strerror): Just what it says on the tin.
3471 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3472 also run for Cygwin; both systems have the same problem with using
3473 GUI facilities in a forked child. Also call syms_of_cygw32,
3474 syms_of_w32select in correct places.
3476 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3477 needs fork-then-exec for daemon launching.
3479 * font.h: Include frame.h.
3481 * image.c: Use the image library cache machinery only when we're
3482 compiling for native WINDOWSNT; Cygwin can use shared libraries
3483 like any other Unixlike system.
3485 * keyboard.c: Clarify a comment regarding the input loop.
3487 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3488 functions directly instead of trying to detect at runtime that our
3489 host operating system supports them. We make this change for two
3490 reasons: Cygwin lacks support for the multibyte character
3491 conversion functions used by the legacy menu code, and Cygwin
3492 never needs to rely on non-Unicode APIs.
3494 * unexw32.c (hinst): Declare extern.
3496 * w32.c: Change header order;
3497 (w32_strerror): Move to w32fns.c because we need it for
3498 non-WINDOWSNT builds.
3500 * w32.h: Add #error macro to make sure we don't include w32.h for
3501 Cygwin builds. Remove w32select declarations.
3503 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3504 w32fns.c. w32console.c is WINDOWSNT-only.
3506 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3507 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3509 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3510 (w32_major_version, w32_minor_version, w32_build_number)
3511 (os_subtype, sound_type): Define here
3512 (w32_defined_color): Make color parameter const for consistency
3513 with other _defined_color functions.
3514 (w32_createwindow): Unconditionally call w32_init_class instead of
3515 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3516 through the code is complex and unnecessary because class
3517 registration is practically free.
3518 (w32_name_of_message): New EMACSDEBUG-only function.
3519 (Fset_message_beep): Move here
3520 (Fx_open_connection): Require that the display name for Windows be
3521 "w32" for consistency, emacsclient disambiguation, and maybe, one
3522 day, multi-window-system support.
3523 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3524 Cygwin files for W32 GUI facilities, since these clearly don't
3525 expect Cygwin names.
3526 (_DebPrint): Define.
3527 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3528 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3529 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3530 (w32_last_error): Remove.
3532 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3534 * w32heap.c (syspage_mask): Declare here.
3535 (cache_system_info): Remove.
3537 * w32inevt.c (faked_key): Define globally, not statically.
3538 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3539 (w32_console_toggle_lock_key): Move to w32fns.c.
3541 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3543 * w32proc.c (_DebPrint): Move to w32fns.c.
3544 * w32select.c: Include string.h, stdio.h for Cygwin.
3545 * w32select.h: New File.
3547 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3549 (w32_message_fd): New variable. Under Cygwin, holds the file
3550 descriptor the system used to tell us about pending thread
3553 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3554 that prevented compilation under non-WINDOWSNT systems.
3556 (w32_initialize): Open /dev/windows and assign it to
3557 w32_message_fd. Provide w32 feature.
3559 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3560 (WM_EMACS_INPUT_READY): add.
3561 (prepend_msg, w32_message_fd): Declare globally.
3564 (keyboard_handle): Use only when WINDOWSNT.
3565 (notify_msg_ready): New function. Posts a message to the main
3566 thread's message queue under CYGWIN, which wakes up the main
3567 thread from select(2) by making the /dev/windows file descriptor
3568 ready. Under WINDOWSNT, it sets an event the same way the old
3571 (post, prepend_msg): Actually call notify_msg_ready instead of
3572 setting the input event directly.
3574 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3576 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3577 but it still has blocs in it, don't return it to the system,
3578 instead of aborting. (Bug#12402)
3580 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3582 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3584 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3585 MAC_OS_X_VERSION_10_6.
3586 (syms_of_nsterm): Remove comment about Panther and above for
3588 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3589 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3590 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3592 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3593 MAC_OS_X_VERSION_10_4.
3595 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3596 MAC_OS_X_VERSION_10_2.
3598 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3600 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3601 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3603 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3604 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3605 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3606 Remove ns_in_resize check.
3607 (ns_clear_frame_area): Remove resize handle code.
3609 * nsfns.m (ns_in_resize): Remove.
3610 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3611 Remove ns_in_resize check.
3613 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3615 Improve sys_siglist detection.
3616 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3617 defined as a macro, as is done in Solaris.
3618 (sys_siglist_entries): New macro.
3619 (save_strsignal): Use it.
3620 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3621 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3623 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3625 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3626 fullscreen/Fullscreen.
3628 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3629 tobar_height is new.
3631 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3632 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3633 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3634 (windowDidResize:): Check for correct window if old style fullscreen.
3635 Capitalize word in comment. Remove incorrect comment.
3636 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3637 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3638 error in drawing background.
3639 (toggleFullScreen:): Remove comment. Rearrange calls.
3640 Set toolbar values to zero, save old height in tobar_height.
3641 Restore tool bar height when leaving fullscreen.
3642 (canBecomeMainWindow): New function.
3644 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3646 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3648 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3650 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3652 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3653 that time stamps of directories could also be changed.
3654 Don't request the too broad GENERIC_WRITE, only the more restrictive
3655 FILE_WRITE_ATTRIBUTES access rights.
3657 * fileio.c (Fset_file_times): Special-case ignoring errors for
3658 directories only on MSDOS, not on MS-Windows.
3660 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3662 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3664 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3666 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3667 see whether CreateFile failed.
3669 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3671 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3672 to avoid similar races.
3673 * keyboard.c (pending_signals): Now bool, not int.
3675 Port timers to OpenBSD, plus check for timer failures.
3676 OpenBSD problem reported by Han Boetes.
3677 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3679 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3680 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3681 like OpenBSD, which has timer_settime but does not declare it.
3682 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3683 whether to use itimerspec-related primitives. All uses of
3684 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3686 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3688 * profiler.c (handle_profiler_signal): Fix a malloc race
3689 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3691 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3693 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3695 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3697 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3698 consistent with the change in return value of 'safe_strsignal'.
3700 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3702 Prefer plain 'static' to 'static inline' (Bug#12541).
3703 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3704 (bidi_set_sor_type, bidi_push_embedding_level)
3705 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3706 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3707 (bidi_cache_search, bidi_cache_ensure_space)
3708 (bidi_cache_iterator_state, bidi_cache_find)
3709 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3710 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3711 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3712 Now 'static', not 'static inline'.
3714 Count overruns when profiling; change units to ns.
3715 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3716 Give extra weight to samples after overruns, to attempt to count
3717 the time more accurately.
3718 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3719 the underlying primitives nominally do ns.
3720 (Fprofiler_cpu_start): Document the change. Mention that
3721 the sampling intervals are only approximate.
3723 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3725 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3727 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3728 case for the special 0 coding-system.

3741 Fix a malloc race condition involving strsignal.
3742 A signal can arrive in the middle of a malloc, and Emacs's signal
3743 handler can invoke strsignal, which can invoke malloc, which is
3744 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3745 Fix it by altering the signal handler so that it does not invoke
3747 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3748 * process.c (status_message): Use const pointer, in case strsignal
3749 is #defined to safe_strsignal.
3750 * sysdep.c (sys_siglist, init_signals): Always define and
3751 initialize a substitute sys_siglist if the system does not define
3752 one, even if HAVE_STRSIGNAL.
3753 (safe_strsignal): Rename from strsignal. Always define,
3754 using sys_siglist. Return a const pointer.
3755 * syssignal.h (safe_strsignal): New decl.
3756 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3758 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3760 * w32proc.c (timer_loop): Fix code that waits for timer
3761 expiration, to avoid high CPU usage.
3763 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3765 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3766 (sweep_weak_table): Remove redundant prototypes.
3768 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3770 * emacs.c: Move the inclusion of TERM_HEADER after including
3771 windows.h on WINDOWSNT. This avoids compilation problems with
3774 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3776 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3777 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3778 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3779 as the previous version used 'void *'.
3781 * ralloc.c (ROUNDUP): Fix last change.
3782 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3785 * w32proc.c <disable_itimers>: New static flag.
3786 (init_timers): Initialize it to zero, after creating the critical
3787 sections used by the timer threads.
3788 (term_timers): Set to 1 before deleting the critical sections.
3789 (getitimer, setitimer): If disable_itimers is non-zero, return an
3790 error indication without doing anything. Reported by Fabrice
3791 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3792 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3794 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3797 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3798 term_ntproc after all the other bookkeeping, to get timers working
3799 as long as possible.
3801 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3803 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3804 Suggested by Juri Linkov in
3805 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3807 Prefer plain 'static' to 'static inline' (Bug#12541).
3808 With static functions, modern compilers inline pretty well by
3809 themselves; advice from programmers often hurts as much as it helps.
3810 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3811 this change shrinks the text size of the Emacs executable by 1.1%
3812 without affecting CPU significantly in my benchmark.

3893 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3895 Revert the FOLLOW-SYMLINKS change for file-attributes.
3896 Doing it right would require several changes to Tramp, and there's
3897 not enough time to get that tested before the freeze today.
3898 * dired.c (directory_files_internal, Ffile_attributes):
3901 * frame.c (x_report_frame_params): Port better to wider ints.
3902 Do not assume that EMACS_UINT is the same width as uprintmax_t,

3935 * w32.c (init_environment, get_emacs_configuration): Support AMD64
3937 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
3938 compatibility with x64.
3940 * vm-limit.c (lim_data): Now size_t.
3941 (check_memory_limits): Adjust prototypes of real_morecore and
3942 __morecore to receive argument of type ptrdiff_t. Use size_t for

4091 HAVE_TIMER_SETTIME is defined.
4093 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
4095 Profiler improvements: more-accurate timers, overflow checks.
4096 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4097 signal.h, setjmp.h. Include systime.h instead.
4098 (saturated_add): New function.
4099 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

4105 All uses changed to store the new value.
4106 (handle_profiler_signal): Rename from sigprof_handler_1,
4107 for consistency with other handlers. Do not check whether
4108 cpu_log is a hash-table if garbage collecting, since it
4109 doesn't matter in that case.

4111 for consistency with other handlers.
4112 (setup_cpu_timer): New function, with much of what used to be in
4113 Fprofiler_cpu_start. Check for out-of-range argument.
4114 Prefer timer_settime if available, and prefer
4115 thread cputime clocks, then process cputime clocks, then
4116 monotonic clocks, to the old realtime clock. Use make_timeval
4117 to round more-correctly when falling back to setitimer.
4118 (Fprofiler_cpu_start): Use it.
4119 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4120 Don't assume that passing NULL as the 2nd argument of setitimer
4121 is the same as passing a pointer to all-zero storage.
4122 Ignore SIGPROF afterwards.
4123 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4124 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4125 non-fatal signal handlers. Ignore SIGPROF on startup.
4126 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4127 in profiler.c, since sysdep.c now uses it.
4129 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4167 * Makefile.in (LIB_TIMER_TIME): New macro.
4169 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
4170 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
4173 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
4175 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.

4183 * character.h (MAYBE_UNIFY_CHAR): Remove.
4184 * charset.c, charset.h (maybe_unify_char): Now static.
4185 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4186 Since this stuff is now private to charset.c, there's no need for
4187 a public macro and no need to inline by hand.

4190 Stefan Monnier <monnier@iro.umontreal.ca>
4191 Juanma Barranquero <lekktu@gmail.com>

4216 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4218 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4220 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4222 Prefer POSIX timers if available.
4223 They avoid a race if the timer is too close to the current time.
4224 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4225 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4226 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4228 2012-09-25 Eli Zaretskii <eliz@gnu.org>

4233 STRING_CHAR_ADVANCE.
4235 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4237 Move Vlibrary_cache to emacs.c and reset before dumping.
4239 * lisp.h (reset_image_types): Declare.
4240 [WINDOWSNT] (Vlibrary_cache): Declare.
4242 * image.c (reset_image_types): New function.
4244 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
4245 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.

4255 * w32proc.c (sys_signal): Handle all signals defined by the
4256 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4257 handlers for signals supported by Windows. Don't override
4258 term_ntproc as the handler for SIGABRT.
4259 (sigaction): Rewrite to call sys_signal instead of duplicating its
4261 (sys_kill): Improve commentary.
4263 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4264 consistency with a signature of a signal handler. All callers
4266 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4267 install term_ntproc as a signal handler for SIGABRT, as that
4268 should be done by the dumped Emacs.
4270 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4272 * w32select.c (term_w32select): Protect against repeated
4273 invocation by setting clipboard_owner to NULL after calling

4277 and term_ntproc to their modified signatures.
4279 * character.c (char_string, string_char): Remove calls to
4280 MAYBE_UNIFY_CHAR. See the discussion starting at
4281 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4284 2012-09-25 Chong Yidong <cyd@gnu.org>
4286 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4288 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4290 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4291 when encountering an unknown bytecode.
4293 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4295 image.c, indent.c: Use bool for booleans.
4296 * dispextern.h (struct image_type): Members valid_p, load, init
4297 now return bool, not int. All uses changed.
4298 * image.c: Omit unnecessary static decls.
4299 (x_create_bitmap_mask, x_build_heuristic_mask):
4300 Return void, not int, since callers don't care about the return value.

4329 Use bool for booleans.
4331 2012-09-24 Chong Yidong <cyd@gnu.org>
4333 * chartab.c (Fset_char_table_default): Obsolete function removed.
4335 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4337 Move pid_t related decls out of lisp.h.
4338 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4339 (interruptible_wait_for_termination):
4340 Move these decls from lisp.h to syswait.h, since they use pid_t.
4341 Needed on FreeBSD; see Herbert J. Skuhra in
4342 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4343 * callproc.c: Include syswait.h.
4345 gnutls.c, gtkutil.c: Use bool for boolean.

4360 * nsmenu.m (ns_update_menubar):
4361 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4362 * xfns.c (Fx_show_tip) [USE_GTK]:
4363 Use bool for boolean.
4364 * gtkutil.c (xg_update_frame_menubar):
4365 * xmenu.c (update_frame_menubar):
4366 Return void, not int, since caller ignores return value.
4367 * gtkutil.c (xg_change_toolbar_position):
4370 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4372 * makefile.w32-in (BLOCKINPUT_H): Remove.

4389 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4391 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4392 fatal_error_backtrace.
4394 * w32proc.c (sys_kill): Undo last change: don't do anything when
4395 invoked to deliver SIGABRT to our own process. This is now
4396 handled by emacs_raise.
4398 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4400 * w32term.c (w32_read_socket): Remove leftover reference to
4401 interrupt_input_pending.
4403 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4405 Do not use SA_NODEFER.
4406 Problem reported by Dani Moncayo in
4407 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4409 * sysdep.c (emacs_abort): Do not reset signal handler.
4410 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4411 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4412 wanted even on POSIXish hosts, and it doesn't work on Windows.
4414 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4416 * xterm.c (x_term_init): Call fixup_locale before and after calling
4417 gtk_init (Bug#12392).
4419 2012-09-23 Chong Yidong <cyd@gnu.org>
4421 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4422 Vdynamic_library_alist.
4424 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4425 (Fgnutls_available_p): Caller changed.
4427 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4428 (Flibxml_parse_xml_region): Likewise.
4430 * dispextern.h (struct image_type): Remove arg from init function.
4432 * image.c (Finit_image_library, lookup_image_type)
4433 (define_image_type): Remove now-unneeded second arg.
4434 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4435 (init_tiff_functions, init_gif_functions, init_svg_functions):
4436 Arglist and w32_delayed_load calling convention changed.
4437 (gs_type): Remove init_gs_functions; there is no such function.
4438 (valid_image_p, make_image): Fix caller to lookup_image_type.
4440 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4442 Simplify and avoid signal-handling races (Bug#12471).
4444 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4445 Avoid recursive loop if there's a fatal error in the function itself.
4446 * atimer.c (pending_atimers):
4447 * blockinput.h: Don't include "atimer.h"; no longer needed.
4448 (interrupt_input_pending): Remove. All uses removed.
4449 pending_signals now counts both atimers and ordinary interrupts.
4450 This is less racy than having three separate pending-signal flags.
4451 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4453 Rename from their upper-case counterparts BLOCK_INPUT,
4454 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4455 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4456 This makes it easier to access volatile variables more accurately.
4457 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4458 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4459 that's more reliable if the code is buggy and sets
4460 interrupt_input_blocked to a negative value. All uses changed.
4461 * atimer.c (deliver_alarm_signal):
4462 Remove. No need to deliver this to the parent; any thread can
4463 handle this signal now. All uses replaced by underlying handler.
4464 * atimer.c (turn_on_atimers):
4465 * dispnew.c (handle_window_change_signal):
4466 * emacs.c (handle_danger_signal):
4467 * keyboard.c (kbd_buffer_get_event):
4468 Don't reestablish signal handler; not needed with sigaction.
4469 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4471 Rework to avoid unnecessary accesses to volatile variables.
4472 (UNBLOCK_INPUT_TO): Now a function.
4473 (totally_unblock_input, unblock_input): New decls.
4474 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4475 (init_data): Remove. Necessary stuff now done in init_signal.
4476 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4477 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4478 (fatal_error_code): Remove; no longer needed.
4479 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4480 it doesn't always backtrace. All uses changed. No need to reset
4481 signal to default, since sigaction and/or die does that for us now.
4482 Use emacs_raise (FOO), not kill (getpid (), FOO).
4483 (main): Check more-accurately whether we're dumping.
4484 Move fatal-error setup to sysdep.c
4485 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4486 * gtkutil.c (xg_get_file_name, xg_get_font):
4487 Remove no-longer-needed signal-mask manipulation.
4488 * keyboard.c, process.c (POLL_FOR_INPUT):
4489 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4490 * keyboard.c (read_avail_input): Remove.
4491 All uses replaced by gobble_input.
4492 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4493 (kbd_buffer_store_event_hold, gobble_input):
4494 (record_asynch_buffer_change) [USABLE_SIGIO]:
4495 (store_user_signal_events):
4496 No need to mess with signal mask.
4497 (gobble_input): If blocking input and there are terminals, simply
4498 set pending_signals to 1 and return. All hooks changed to not
4499 worry about whether input is blocked.
4500 (process_pending_signals): Clear pending_signals before processing
4501 them, in case a signal comes in while we're processing.
4502 By convention callers now test pending_signals before calling us.
4503 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4504 New functions, to support changes to blockinput.h.
4505 (handle_input_available_signal): Now extern.
4506 (reinvoke_input_signal): Remove. All uses replaced by
4508 (quit_count): Now volatile, since a signal handler uses it.
4509 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4510 All callers changed. Block SIGINT only if not already blocked.
4511 Clear sigmask reliably, even if Fsignal returns, which it can.
4512 Omit unnecessary accesses to volatile var.
4513 (quit_throw_to_read_char): No need to restore sigmask.
4514 * keyboard.c (gobble_input, handle_user_signal):
4515 * process.c (wait_reading_process_output):
4516 Call signal-handling code rather than killing ourselves.
4517 * lisp.h: Include <float.h>, for...
4518 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4519 (pending_signals): Now volatile.
4520 (syms_of_data): Now const if IEEE floating point.
4521 (handle_input_available_signal) [USABLE_SIGIO]:
4522 (terminate_due_to_signal, record_child_status_change): New decls.
4523 * process.c (create_process): Avoid disaster if memory is exhausted
4524 while we're processing a vfork, by tightening the critical section
4526 (send_process_frame, process_sent_to, handle_pipe_signal)
4527 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4529 (send_process): No need for setjmp/longjmp any more, since the
4530 SIGPIPE stuff is now gone. Instead, report an error if errno
4532 (record_child_status_change): Now extern. PID and W are now args.
4533 Return void, not bool. All callers changed.
4534 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4535 Remove. All uses removed. This bug should be fixed now in a
4537 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4538 and record the child status change directly. This avoids the
4539 need to futz with the signal mask.
4540 (process_fatal_action): Move here from emacs.c.
4541 (emacs_sigaction_flags): New function, containing
4542 much of what used to be in emacs_sigaction_init.
4543 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4544 caught by emacs, to make races less likely.
4545 (deliver_process_signal): Rename from handle_on_main_thread.
4547 (BACKTRACE_LIMIT_MAX): Now at top level.
4548 (thread_backtrace_buffer, threadback_backtrace_pointers):
4550 (deliver_thread_signal, deliver_fatal_thread_signal):
4551 New functions, for more-accurate delivery of thread-specific signals.
4552 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4553 (deliver_arith_signal): Handle in this thread, not
4554 in the main thread, since it's triggered by this thread.
4555 (maybe_fatal_sig): New function.
4556 (init_signals): New arg DUMPING so that we can be more accurate
4557 about whether we're dumping. Caller changed.
4558 Treat thread-specific signals differently from process-general signals.
4559 Block all signals while handling fatal error; that's safer.
4560 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4562 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4563 Ignore SIGPIPE unless batch.
4564 (emacs_backtrace): Output backtrace for the appropriate thread,
4565 which is not necessarily the main thread.
4566 * syssignal.h: Include <stdbool.h>.
4567 (emacs_raise): New macro.
4568 * xterm.c (x_connection_signal): Remove; no longer needed
4569 now that we use sigaction.
4570 (x_connection_closed): No need to mess with sigmask now.
4571 (x_initialize): No need to reset SIGPIPE handler here, since
4572 init_signals does this for us now.
4574 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4576 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4577 background rect may be larger (Bug#12245).
4579 2012-09-23 Chong Yidong <cyd@gnu.org>
4581 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4583 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4585 * .gdbinit: Just stop at fatal_error_backtrace.
4586 See Stefan Monnier's request in
4587 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4588 Remove no-longer-used query of system type.
4590 2012-09-22 Chong Yidong <cyd@gnu.org>
4592 * search.c (Freplace_match): Doc fix (Bug#12325).
4594 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4596 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4597 (Fline_end_position): Doc fix.
4599 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4601 2012-09-22 Chong Yidong <cyd@gnu.org>
4603 * dispextern.h (struct image_type): Add new slot, storing a type
4604 initialization function.
4606 * image.c (define_image_type): Call the image initializer function
4607 if it is defined. Arguments and return value changed.
4608 (valid_image_p, make_image): Callers changed.
4609 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4610 (gif_type, imagemagick_type, svg_type, gs_type):
4611 Add initialization functions.
4612 (Finit_image_library): Call lookup_image_type.
4613 (CHECK_LIB_AVAILABLE): Macro deleted.
4614 (lookup_image_type): Call define_image_type here, rather than via
4615 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4616 (syms_of_image): Move define_image_type calls for xbm_type and
4617 pbm_type to lookup_image_type.
4619 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4621 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4622 'idle_timers' from here ...
4623 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4624 lists, to avoid infloops when the timer does something stupid,
4625 like reinvoke itself with the same or smaller time-out.
4628 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4630 * window.c (Fsplit_window_internal): Handle only Qt value of
4631 Vwindow_combination_limit separately.
4632 (Qtemp_buffer_resize): New symbol.
4633 (Vwindow_combination_limit): New default value.
4636 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4638 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4639 the new overlay string. (Bug#10159)
4641 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4643 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4644 or that fprintf is async-signal-safe. POSIX doesn't require
4647 2012-09-22 Chong Yidong <cyd@gnu.org>
4649 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4652 2012-09-22 Kenichi Handa <handa@gnu.org>
4654 * composite.c (composition_reseat_it): Handle the case that a
4655 grapheme cluster is not covered by a single font (Bug#12352).
4657 2012-09-21 Chong Yidong <cyd@gnu.org>
4659 * image.c (define_image_type): Avoid adding duplicate types to
4660 image_types (Bug#12463). Suggested by Jörg Walter.
4662 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4664 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4665 (print_load_command_name): Add case LC_DATA_IN_CODE.
4666 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4668 2012-09-21 Glenn Morris <rgm@gnu.org>
4670 * eval.c (Frun_hook_with_args_until_success)
4671 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4673 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4675 * fileio.c (Ffile_selinux_context): Only call freecon when
4676 lgetfilecon succeeded.
4677 (Fset_file_selinux_context): Likewise. (Bug#12444)
4679 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4681 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4682 reordering, locate the cursor by calling set_cursor_from_row; if
4683 that fails, clear the desired glyph matrix before returning a
4684 failure indication to the caller. Fixes leaving garbled display
4685 when fast scrolling with a down-key. (Bug#12403)
4686 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4687 scrolling through multibyte text.
4689 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4691 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4692 calling mark_vectorlike since that's the one that marks the window.
4693 (mark_discard_killed_buffers): Mark the final cdr.
4694 * window.h (struct window): Move prev/next_buffers to the
4695 non-standard fields.
4696 * window.c (make_window): Initialize prev/next_buffers manually.
4698 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4700 Omit unused arg EXPECTED from socket hooks.
4701 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4702 * nsterm.m (ns_term_init):
4703 * termhooks.h (struct terminal.read_socket_hook):
4704 * w32inevt.c (w32_console_read_socket):
4705 * w32term.c (w32_read_socket):
4706 * xterm.c (XTread_socket):
4707 Omit unused arg EXPECTED. All callers changed.
4708 (store_user_signal_events): Return void, not int, since callers no
4709 longer care about the return value. All uses changed.
4711 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4713 * w32gui.h (XParseGeometry): Do not declare.
4715 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4717 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4718 Ignore 'expected'. See Eli Zaretskii in
4719 <http://bugs.gnu.org/12471#8> (last line).
4721 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4722 (XParseGeometry): Now static. Substitute extremal values for
4723 values that are out of range.
4725 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4727 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4729 * nsfns.m (XParseGeometry): Remove.
4730 (Fx_create_frame): Call x_set_offset to correctly interpret
4731 top_pos in geometry.
4733 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4734 (Fx_parse_geometry): If there is a space in string, call
4735 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4737 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4739 * search.c (scan_buffer): Use character positions in calls to
4740 region_cache_forward and region_cache_backward, not byte
4741 positions. (Bug#12196)
4743 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4744 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4746 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4747 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4748 emacs_blocked_malloc, now deleted.
4750 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4752 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4753 The workaround was for improving performance on Solaris 2.4, but
4754 is getting in the way now. Emacs will still work if someone is
4755 still running Solaris 2.4 in a museum somewhere; Sun dropped
4756 support for Solaris 2.4 in 2003.
4757 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4758 * process.c (create_process) [HAVE_WORKING_VFORK]:
4759 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4760 since Emacs no longer uses vfork on that platform.
4762 2012-09-17 Glenn Morris <rgm@gnu.org>
4764 * emacs.c: Use COPYRIGHT.
4766 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4768 Remove configure's --without-sync-input option (Bug#12450).
4769 When auditing signal-handling in preparation for cleaning it up,
4770 I found that SYNC_INPUT has race conditions and would be a real
4771 pain to fix. Since it's an undocumented and deprecated
4772 configure-time option, now seems like a good time to remove it.
4773 Also see <http://bugs.gnu.org/11080#16>.
4774 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4775 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4776 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4777 (malloc_hysteresis):
4778 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4779 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):

4782 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4783 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4784 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4785 Remove. All uses removed.
4786 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4787 implementation, one that depends on whether the new macro
4788 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4790 * atimer.c (run_timers, handle_alarm_signal):
4791 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4792 (handle_async_input, process_pending_signals)
4793 (handle_input_available_signal, init_keyboard):
4794 * nsterm.m (ns_read_socket):
4795 * process.c (wait_reading_process_output):
4796 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4797 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4799 * xterm.c (XTread_socket):
4801 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4802 * eval.c (handling_signal): Remove. All uses removed.
4803 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4804 All uses replaced with the SYNC_INPUT version.
4805 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4807 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4810 * font.c (Ffont_shape_gstring): Remove unused local.
4812 2012-09-16 Glenn Morris <rgm@gnu.org>
4814 * Makefile.in (clean): No longer run nextstep's clean.
4816 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4818 (ns-app): Move here from ns.mk, and simplify.
4819 (clean): Simplify nextstep entry.
4820 * ns.mk: Remove file.
4822 2012-09-17 Kenichi Handa <handa@gnu.org>
4824 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4825 not covert the last few charactes.
4827 2012-09-16 Kenichi Handa <handa@gnu.org>
4829 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4830 here, but just check the validity of glyphs in the glyph-string.
4832 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4834 * window.c (Fwindow_parameter, Fset_window_parameter):
4835 Accept any window as argument (Bug#12452).
4837 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4839 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4840 to ns_term_init to avoid memory leak.
4842 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4843 explicit retain/release.
4844 (ns_term_init): Only allow one display. Initialize outerpool and
4847 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4849 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4850 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4851 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4852 the Microsoft problem in a different way, by altering ../nt/config.nt.
4854 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4869 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4870 by lisp.h. This completes removal of setjmp.h inclusion
4871 erroneously announced in the previous commit. (Bug#12446)
4873 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4876 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4877 not defined as a macro. The latter happens on MS-Windows.
4880 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4882 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4883 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4884 Some instances of '#include <setjmp.h>' removed, if the
4885 only reason for the instance was because "lisp.h" was included.
4886 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4887 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4888 and _longjmp with the new symbols. Emacs already uses _setjmp if
4889 available, so this change affects only POSIXish hosts that have
4890 sigsetjmp but not _setjmp, such as some versions of Solaris and
4891 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4892 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4893 (png_load_body) [HAVE_PNG]:
4894 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4895 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4896 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4897 since PNG requires jmp_buf. This is the only exception to the
4898 general rule that we now use sys_setjmp and sys_longjmp.
4899 This exception is OK since this code does not change the signal
4900 mask or longjmp out of a signal handler.
4902 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4904 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4905 Include "syssignal.h", for 'main_thread'.
4907 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4909 Avoid out-of-range marker position (Bug#12426).
4910 * insdel.c (replace_range, replace_range_2):
4911 Adjust markers before overlays, as suggested by comments.
4912 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4913 Remove redundant check before calling offset_intervals.
4915 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4917 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4918 current buffer (Bug#12387).
4920 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4922 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4924 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4926 Use a more backwards-compatible timer format (Bug#12430).
4927 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4928 vector element, not from the 4th, since PSECS is now at the end.
4929 (Fcurrent_idle_time): Doc fix.
4931 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4933 Function to mark objects and remove killed buffers at once.
4934 * alloc.c (discard_killed_buffers): Rename to ...
4935 (mark_discard_killed buffers) ... new name. Add marking
4936 of remaining objects. Fix comment. Adjust users.
4937 (mark_object): Do not touch frame buffer lists here.
4938 * frame.c (delete_frame): Reset frame buffer lists here.
4940 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4942 Better workaround for GNOME bug when --enable-gcc-warnings.
4943 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4944 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4945 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4947 Simplify SIGIO usage (Bug#12408).
4948 The code that dealt with SIGIO was crufty and confusing, e.g., it
4949 played tricks like "#undef SIGIO" but these tricks were not used
4950 consistently. Simplify mostly by not #undeffing standard symbols,
4951 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4952 or not as we please) rather than "defined SIGIO" (standard symbol
4953 that we probably shouldn't #undef).
4954 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4955 Modules that need it can include it.
4956 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4957 * dispextern.h (ignore_sigio): New decl.
4958 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4959 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4960 * emacs.c (shut_down_emacs):
4961 * keyboard.c (kbd_buffer_store_event_hold):
4962 Use ignore_sigio rather than invoking 'signal' directly.
4963 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4965 (FIONREAD, SIGIO): Do not #undef.
4966 (tty_read_avail_input): Use #error rather than a syntax error.
4967 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4968 for I_PIPE, used by SETUP_SLAVE_PTY.
4969 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4970 * sysdep.c (croak): Remove; no longer needed. This bit of
4971 temporary code, with Fred N. Fish's comment that it's temporary,
4972 has been in Emacs since at least 1992!
4973 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4974 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4975 * syssignal.h (croak): Remove decl.
4976 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4977 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4978 now that we're termios-only.
4979 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4980 * term.c (dissociate_if_controlling_tty): Use #error rather than
4983 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4984 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4985 to work around GNOME bug 683906.
4986 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4987 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4988 This works around GCC bug 54561.
4990 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4992 More fixes for 'volatile' and setjmp/longjmp.
4993 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4994 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4995 (png_load_body) [HAVE_PNG]:
4996 (jpeg_load_body) [HAVE_JPEG]:
4997 New function, with most of the old parent function's body.
4998 (png_load) [HAVE_PNG]:
4999 (jpeg_load) [HAVE_JPEG]:
5000 Invoke the new function, to avoid longjmp munging our locals.
5001 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5002 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5003 longjmp is passed 2, as the C standard doesn't guarantee this.
5004 Instead, store the failure code into mgr->failure_code.
5006 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5008 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5009 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5010 (syms_of_keyboard): Remove support for unread-command-char.
5012 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5014 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5015 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5016 violation. (Bug#12426)
5018 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5020 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5022 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5024 * eval.c: Add `inhibit-debugger'.
5025 (Qinhibit_debugger): New symbol.
5026 (call_debugger): Bind it instead of Qdebug_on_error.
5027 (maybe_call_debugger): Test Vinhibit_debugger.
5028 (syms_of_eval): Define inhibit-debugger.
5029 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5030 (syms_of_xdisp): Remove inhibit-debug-on-message.
5032 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5034 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5035 If a nonvolatile local variable is written before a _longjmp to
5036 the frame containing the variable, and is read after the _longjmp,
5037 the value read is indeterminate. Some local variables of type
5038 'struct handler' and 'struct catchtag' are used in this way, so
5039 mark each of their slots as volatile if the slot can be set before
5040 _longjmp and read afterwards.
5041 * lisp.h (struct handler): var and chosen_clause are now volatile.
5042 (struct catchtag): val, next, and pdlcount are now volatile.
5044 * bidi.c (bidi_push_it, bidi_pop_it):
5045 * fns.c (copy_hash_table):
5046 * image.c (define_image_type):
5047 * keyboard.c (kbd_buffer_store_event_hold):
5048 * process.c (Fprocess_send_eof):
5049 * xfaces.c (x_create_gc) [HAVE_NS]:
5050 * xgselect.c (xg_select):
5051 Prefer assignment to memcpy when either will do.
5053 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5054 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5055 time an item is removed. No need to mark this function 'inline';
5056 the compiler knows better than we do.
5058 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5060 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5061 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5062 to change_frame_size (Bug#12388).
5063 (windowDidResize:): Pass YES to updateFrameSize.
5065 * nsterm.h: Add delay parameter to updateFrameSize.
5067 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5069 Discard killed buffers from deleted window and frame objects.
5070 This reduces an amount of references to killed buffers and
5071 helps GC to reclaim them faster.
5072 * alloc.c (discard_killed_buffers): New function.
5073 (mark_object): Use it for deleted windows and frames.
5074 (mark_object): If symbol's value is set up for a killed buffer
5075 or deleted frame, restore its global binding.
5076 * data.c (swap_in_global_binding): Add GC notice.
5077 (swap_in_symval_forwarding): Use convenient set_blv_where.
5078 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5079 * window.h: ... to here.
5081 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5083 Convenient macro to check whether the buffer is live.
5084 * buffer.h (BUFFER_LIVE_P): New macro.
5085 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5086 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5088 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5090 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5091 composition cases (Bug#12364).
5093 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5094 overhang of succeeding glyphs overlapping box cursor.
5096 * w32term.c (x_draw_glyph_string): Likewise.
5098 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5100 Simplify, document, and port floating-point (Bug#12381).
5101 The porting part of this patch fixes bugs on non-IEEE platforms
5102 with frexp, ldexp, logb.
5103 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5105 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5106 support, by removing commented-out code and briefly listing the
5107 C89 functions excluded. The commented-out stuff was confusing
5108 maintenance, e.g., we thought we needed cbrt but it was commented out.
5109 (logb): Remove decl; no longer needed.
5110 (isfinite): New macro, if not already supplied.
5111 (isnan): Don't replace any existing macro.
5112 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5113 are present on all C89 platforms.
5114 (Ffrexp): Do not special-case zero, as frexp does the right thing
5116 (Flogb): Do not use logb, as it doesn't have the desired meaning
5117 on hosts that use non-base-2 floating point. Instead, stick with
5118 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5119 frexp, to avoid getting an unspecified result.
5121 * xdisp.c (Qinhibit_debug_on_message): Now static.
5123 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5125 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5126 NSBezierPath (Bug#12131).
5128 2012-09-10 Chong Yidong <cyd@gnu.org>
5130 * fns.c (Fdelq, Fdelete): Doc fix.
5132 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5134 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5135 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5137 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5139 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5140 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5143 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5145 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5146 left fringe if the window has a left margin. This avoids leaving
5147 traces of the cursor because its leftmost pixel is not drawn over.
5149 * dispnew.c (update_window_line): When the left margin area of a
5150 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5151 that screen line. (Bug#12277)
5153 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5155 Assume C89 or later for math functions (Bug#12381).
5156 This simplifies the code, and makes it a bit smaller and faster,
5157 and (most important) makes it easier to clean up signal handling
5158 since we can stop worring about floating-point exceptions in
5159 library code. That was a problem before C89, but the problem
5160 went away many years ago on all practical Emacs targets.
5161 * data.c, image.c, lread.c, print.c:
5162 Don't include <math.h>; no longer needed.
5163 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5164 might be autoconfigured, as that never happens.
5166 * doprnt.c (DBL_MAX_10_EXP):
5167 * print.c (DBL_DIG):
5168 Remove. C89 or later always defines these.
5169 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5170 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5171 (arith_error, domain_error, domain_error2):
5172 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5173 no longer needed -- we simply return what C returns. All uses removed.
5174 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5176 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5177 Remove. All uses expanded, as these macros are no longer used
5178 more than once and are now more trouble than they're worth.
5179 (Ftan): Use tan, not sin / cos.
5180 (Flogb): Assume C89 frexp.
5181 (fmod_float): Assume C89 fmod.
5182 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5183 (init_floatfns): Remove. All uses removed.
5185 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5187 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5188 compositeToPoint for OSX < 10.6 (Bug#12390).
5190 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5192 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5193 This produces more-accurate results.
5195 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5197 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5198 changes (Bug#12088).
5200 2012-09-08 Chong Yidong <cyd@gnu.org>
5202 * syntax.c (Fstring_to_syntax): Doc fix.
5204 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5206 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5207 in the internal border.
5208 (x_set_window_size): Remove static variables and their usage.
5209 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5210 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5211 Remove fringe/internal border adjustment (Bug#11052).
5212 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5213 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5214 (ns_fix_rect_ibw): Remove.
5215 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5216 (ns_dumpglyphs_box_or_relief): Ditto.
5217 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5219 (ns_dumpglyphs_image): Ditto.
5220 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5222 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5223 their usage. Add fringe_extended_p and its use as in other terms.
5224 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5225 scroll bar was removed.
5226 (updateFrameSize): New function.
5227 (windowDidResize): Move code to updateFrameSize and call it.
5229 * nsterm.h (EmacsView): Add updateFrameSize.
5231 2012-09-07 Chong Yidong <cyd@gnu.org>
5233 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5235 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5237 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5239 More signal-handler cleanup (Bug#12327).
5240 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5241 Problem introduced when merging patches. Noted by Eli Zaretskii in
5242 <http://bugs.gnu.org/12327#67>.
5243 * floatfns.c: Comment fix.
5244 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5245 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5246 and anyway the declaration is harmless even if SIGDANGER is not defined.
5247 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5248 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5249 source files not surprisingly expected syssignal.h to define, or
5250 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5251 Include <sys/ioctl.h>, for FIONREAD.
5252 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5253 This eliminates a problem whereby other files mysteriously had
5254 to include "syssignal.h" before including "systty.h" if they
5255 wanted to use "#ifdef SIGIO".
5257 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5259 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5261 * w32.c (sigemptyset): Empty the set.
5262 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5264 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5266 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5268 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5269 (mark_object): Likewise for frame objects.
5271 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5273 * syssignal.h (handle_on_main_thread): Always declare,
5274 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5275 This ports to platforms without HAVE_PTHREAD.
5277 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5279 Signal-handler cleanup (Bug#12327).
5280 Emacs's signal handlers were written in the old 4.2BSD style with
5281 sigblock and sigmask and so forth, and this led to some
5282 inefficiencies and confusion. Rewrite these to use
5283 pthread_sigmask etc. without copying signal sets around. Also,
5284 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5285 'signal', and instead use functions that do not attempt to take
5286 over the system name space. This patch causes Emacs's text
5287 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5288 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5289 Do not include <signal.h> or "syssignal.h", as these
5290 modules do not use signals.
5291 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5292 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5293 Do not include <signal.h>, as "syssignal.h" does that for us now.
5294 * atimer.c (sigmask_atimers): New function.
5295 (block_atimers, unblock_atimers): New functions,
5296 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5298 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5299 no longer needed here.
5300 * emacs.c (main): Inspect existing signal handler with sigaction,
5301 so that there's no need to block and unblock SIGHUP.
5302 * sysdep.c (struct save_signal): New member 'action', replacing
5303 old member 'handler'.
5304 (save_signal_handlers, restore_signal_handlers):
5305 Use sigaction instead of 'signal' to save and restore.
5306 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5307 New function. All users of 'signal' modified to use set_sighandler
5308 if they're writeonly, and to use sys_signal if they're read+write.
5309 (emacs_sigaction_init, forwarded_signal): New functions.
5310 (sys_signal): Remove. All uses replaced by calls to sigaction
5311 and emacs_sigaction_init, or by direct calls to 'signal'.
5312 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5313 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5314 all uses replaced by pthread_sigmask etc. calls.
5315 * syssignal.h: Include <signal.h>.
5316 (emacs_sigaction_init, forwarded_signal): New decls.
5317 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5318 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5319 (sigmask, sys_sigmask): Remove; no longer needed.
5320 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5321 (sigblock, sigunblock, sigfree):
5322 (sigsetmask) [!defined sigsetmask]:
5323 Remove. All uses replaced by pthread_sigmask.
5324 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5325 no longer need to be replaced, and its typical old uses
5326 are now done via emacs_sigaction_init and sigaction.
5327 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5328 (sys_sigdel): Remove; unused.
5329 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5331 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5333 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5334 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5336 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5338 Explicitly mark buffer_defaults and buffer_local_symbols.
5339 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5340 mark_local_symbols here.
5341 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5342 since special buffers aren't marked here any more.
5343 (allocate_buffer): Chain new buffer with all_buffers here...
5344 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5346 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5347 (syms_of_buffer): Remove staticpro of the above.
5348 (init_buffer_once): Set names for buffer_defaults and
5349 buffer_local_symbols.
5351 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5353 Use bool for booleans in font-related modules.
5354 * font.c (font_intern_prop, font_style_to_value)
5355 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5356 (generate_otf_features, font_check_otf_features, font_check_otf)
5357 (font_match_p, font_list_entities, font_at):
5358 * fontset.c (fontset_id_valid_p, reorder_font_vector
5359 (fontset_find_font, Fset_fontset_font)
5360 (face_suitable_for_char_p) [0]:
5361 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5362 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5363 (m17n_flt_initialized, ftfont_shape_by_flt):
5364 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5365 * nsfont.m (nsfont_draw):
5366 * w32font.c (w32font_draw):
5367 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5368 Use bool for booleans.
5369 * font.h: Adjust to above API changes.
5370 (struct font, struct font_driver, struct font_driver_list):
5371 Use bool for booleans.
5372 (struct font): Remove useless member encoding_type.
5374 * fontset.c, xftfont.c: Omit unnecessary static decls.
5376 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5378 * alloc.c (mark_object): Revert window marking code
5379 since it's unsafe for the Fset_window_configuration.
5381 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5383 Fix race conditions with signal handlers and errno (Bug#12327).
5384 Be more systematic about preserving errno whenever a signal
5385 handler returns, even if it's not in the main thread. Do this by
5386 renaming signal handlers to distinguish between signal delivery
5387 and signal handling. All uses changed.
5388 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5389 * data.c (deliver_arith_signal): Rename from arith_error.
5390 * dispnew.c (deliver_window_change_signal): Rename from
5391 window_change_signal.
5392 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5393 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5394 * keyboard.c (deliver_input_available_signal): Rename from
5395 input_available_signal.
5396 (deliver_user_signal): Rename from handle_user_signal.
5397 (deliver_interrupt_signal): Rename from interrupt_signal.
5398 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5399 (deliver_child_signal): Rename from sigchld_handler.
5400 * atimer.c (handle_alarm_signal):
5401 * data.c (handle_arith_signal):
5402 * dispnew.c (handle_window_change_signal):
5403 * emacs.c (handle_fatal_signal, handle_danger_signal):
5404 * keyboard.c (handle_input_available_signal):
5405 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5406 * process.c (handle_pipe_signal, handle_child_signal):
5407 New functions, with the actual signal-handling code taken from the
5408 original respective signal handlers, sans the sporadic attempts to
5409 preserve errno, since that's now done by handle_on_main_thread.
5410 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5411 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5412 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5414 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5415 Move initialization of main_thread to sysdep.c's init_signals.
5416 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5417 our usage, and simplifies the mainline code.
5418 (record_child_status_change): New static function, as a helper
5419 for handle_child_signal, and with most of the old child handler's
5421 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5422 (handle_child_signal): Use the above.
5423 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5424 Moved here from emacs.c.
5425 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5426 code moved here from emacs.c's main function.
5427 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5428 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5429 This lets callers save and restore errno properly.
5431 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5433 Remove redundant or unused things here and there.
5434 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5435 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5436 * editfns.c (Fcompare_buffer_substrings): Likewise.
5437 * frame.h (struct terminal, struct font_driver_list):
5438 Remove redundant declarations.
5439 * window.h (Qleft, Qright): Likewise.
5441 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5443 Do not mark objects from deleted buffers, windows and frames.
5444 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5445 (mark_object): Likewise for windows and frames.
5447 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5449 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5450 buffer_defaults and buffer_local_symbols as valid objects.
5451 Return special value to denote them.
5453 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5455 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5456 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5457 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5458 (file_name_absolute_p, Fsubstitute_in_file_name):

5461 (Finsert_file_contents, choose_write_coding_system)
5462 (Fwrite_region, build_annotations, a_write, e_write)
5464 * filelock.c (boot_time_initialized, get_boot_time)
5465 (get_boot_time_1, lock_file_1, within_one_second):
5466 * floatfns.c (in_float):
5467 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5468 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5469 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5470 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5471 * window.c (compare_window_configurations):
5472 Use bool for booleans.
5473 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5474 (Fdefault_file_modes): Now mode_t, not int, for modes.
5475 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5476 (internal_delete_file): Now returns void, not a (boolean) int,
5477 since nobody was looking at the return value.
5478 * lisp.h, window.h: Adjust to above API changes.
5480 * xdisp.c (set_message): Simplify and reindent last change.
5482 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5484 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.

5488 * eval.c (call_debugger): Make the function non-static so that we
5489 can call it from set_message.
5491 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5492 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5494 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5496 Give more-useful info on a fatal error (Bug#12328).
5497 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5498 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5499 of doing the work ourselves.
5500 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5501 do most of the work.
5502 (fatal_error_backtrace): New function, taken from the guts
5503 of the old fatal_error_signal, but with a new option to output
5505 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5506 info about the signal than just its number.
5507 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5508 * sysdep.c: Include <execinfo.h>
5509 (emacs_backtrace): New function, taken partly from the previous
5510 code of the 'die' function.
5511 (emacs_abort): Call fatal_error_backtrace rather than abort.
5513 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5515 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5516 eager (load-time) macro-expansion.
5517 * lisp.mk (lisp): Add macroexp.
5519 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5521 Simplify redefinition of 'abort' (Bug#12316).
5522 Do not try to redefine the 'abort' function. Instead, redo
5523 the code so that it calls 'emacs_abort' rather than 'abort'.
5524 This removes the need for the NO_ABORT configure-time macro
5525 and makes it easier to change the abort code to do a backtrace.
5526 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5527 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5528 Remove; sysdep.c's emacs_abort now takes its place.
5529 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5530 'abort' changed to use 'emacs_abort'.
5531 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5532 (abort) [!defined abort]: Rename to ...
5533 (emacs_abort): ... new name.
5534 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5535 the place of the old 'abort' in emacs.c.
5536 * w32.c, w32fns.c (abort): Do not #undef.
5537 * w32.c (emacs_abort): Rename from w32_abort.
5539 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5541 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5542 offsets[j].dv, since the y axis of the screen coordinates points
5543 down, while the y axis of the font definition coordinates points
5544 up. This fixes display of Arabic diacritics such as KASRA and
5545 KASRATAN. (Bug#11860)
5547 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5549 Be more systematic about _setjmp vs setjmp.
5550 * alloc.c (test_setjmp, mark_stack):
5551 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5552 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5553 (png_load, my_error_exit, jpeg_load):
5554 * process.c (send_process_trap, send_process):
5555 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5556 The underscored versions are up to 30x faster on some hosts.
5557 Formerly, the code used setjmp+longjmp sometimes and
5558 _setjmp+_longjmp at other times, with no particular reason to
5559 prefer setjmp+longjmp.
5561 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5563 Fix minor problem found by static checking.
5564 * buffer.c (Fdelete_all_overlays): Return nil.
5566 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5568 * buffer.c (Fdelete_all_overlays): New function.
5570 2012-09-03 Chong Yidong <cyd@gnu.org>
5572 * gtkutil.c: Add extern decl for Qxft.
5574 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5576 * emacs.c, eval.c: Use bool for boolean.
5577 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

5588 All callers changed.
5589 * eval.c (interactive_p): Omit always-true boolean argument
5590 EXCLUDE_SUBRS_P. All callers changed.
5591 * dispextern.h, lisp.h: Reflect above API changes.
5592 * firstfile.c (dummy): Use the address of 'main', whose signature
5593 won't change, instead of the address of 'initialize', whose
5594 signature just changed from int to bool.
5595 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5596 * msdos.c (fatal_error_in_progress): ... from here.
5597 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5599 (redisplay_internal, unwind_redisplay): Simply clear
5600 REDISPLAYING_P when unwinding, instead of saving its previous,
5601 always-false value and then restoring it.
5603 Clean up some extern decls.
5604 Mostly, this hoists extern decls out of .c files and into .h files.
5605 That way, we're more likely to catch errors if the interfaces change.
5606 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5607 declare xg_mark_data.
5608 * dispextern.h (x_frame_parm_handlers):
5610 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

5623 * process.c (QCfamily, QCfilter):
5624 * widget.c (free_frame_faces):
5625 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5626 * xfont.c (x_clear_errors):
5627 * xterm.c (x_frame_parm_handlers):
5628 Remove now-redundant extern decls.
5629 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5630 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5632 * xfaces.c: Remove unnecessary static decls.
5633 * xterm.c (updating_frame): Remove decl of nonexistent object.
5635 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5636 when building globals.h, as the objects that are not built on
5637 this host are not needed to compile C files on this host.
5639 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5641 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5655 (make_buffer_string, make_buffer_string_both)
5656 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

5668 (set_intervals_multibyte_1, set_intervals_multibyte):
5669 * keyboard.c (decode_timer):
5670 Use bool for boolean.
5671 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5672 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5674 2012-09-02 Chong Yidong <cyd@gnu.org>

5679 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5681 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5682 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

5689 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5691 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5692 more than one grapheme cluster passed to the shaper: compute the
5693 offset adjustment values separately for each cluster. (Bug#11860)
5695 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5696 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5697 about implicit conversions from integer to pointer.
5699 2012-09-01 Daniel Colascione <dancol@dancol.org>
5701 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5702 system used too early.
5704 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5706 Better seed support for (random).

5742 window-system headers.
5744 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
5747 * keyboard.c: Include TERM_HEADER instead of listing all possible
5748 window-system headers.
5750 * image.c: Include TERM_HEADER instead of listing all possible
5751 window-system headers. Declare Vlibrary_cache when compiling for
5754 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
5755 window system declarations.
5757 * frame.h: Move common functions here: set_frame_menubar,
5758 x_set_window_size, x_sync, x_get_focus_frame,
5759 x_set_mouse_position, x_set_mouse_pixel_position,
5760 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5781 the current window system; include in list of objects to link into
5784 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5786 Remove mark_ttys function and fix tty_display_info initialization.
5787 * lisp.h (mark_ttys): Remove prototype.
5788 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5789 to mark_ttys because all possible values of 'top_frame' slot are
5790 the frames which are reachable from Vframe_list.
5791 * term.c (mark_ttys): Remove.
5792 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5794 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5796 Change struct frame bitfields from unsigned char to unsigned.
5797 * frame.h (struct frame): Change type of 'display_preempted',

5799 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
5800 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
5801 bitfields from unsigned char to unsigned.

5816 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
5817 for GCC 4.7.1 x86-64.
5819 2012-08-30 Glenn Morris <rgm@gnu.org>
5821 * lread.c (init_lread): For out-of-tree builds, only add the
5822 source directory's site-lisp dir to the load-path if it exists,
5823 consistent with in-tree builds. (Bug#12302)
5825 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5827 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

5837 (addSplit): Remove return self, declare return value as void.
5838 (clicked:): Remove return self, declare return value as void.
5839 Set dialog_return to button_values[seltag]. Code formatting change.

5841 Code formatting change.
5842 (timeout_handler:): Set timer_fired to YES.
5843 (runDialogAt:): Set timer_fired to NO.
5844 Handle click on close button as quit.
5846 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5847 Add window_closed and button_values. Add void as return value for
5848 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5849 Add process_dialog as new member.
5851 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5853 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5935 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
5936 Initialize dialog_return.
5937 (windowShouldClose:): Use stop instead of stopModalWithCode.
5938 (clicked:): Ditto, and also set dialog_return (Bug#12258).
5939 (timeout_handler:): Use stop instead of abortModal. Send a dummy
5941 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
5944 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
5946 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
5947 * composite.c (find_composition, composition_gstring_p)
5948 (composition_reseat_it, find_automatic_composition):
5949 * data.c (let_shadows_buffer_binding_p)
5950 (let_shadows_global_binding_p, set_internal, make_blv)
5951 (Fmake_variable_buffer_local, Fmake_local_variable)
5952 (Fmake_variable_frame_local, arithcompare, cons_to_unsigned)
5953 (cons_to_signed, arith_driver):
5954 * dbusbind.c (xd_in_read_queued_messages):
5955 * dired.c (directory_files_internal, file_name_completion):
5956 Use bool for booleans.
5957 * dired.c (file_name_completion):
5958 * process.h (fd_callback):
5959 Omit int (actually boolean) argument. It wasn't being used.
5961 * composite.h, lisp.h: Reflect above API changes.
5963 * cmds.c, coding.c: Use bool for booleans.
5964 * cmds.c (move_point, Fself_insert_command):
5965 * coding.h (struct composition status, struct coding_system):
5966 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
5967 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)
5968 (emacs_mule_char, decode_coding_emacs_mule)

5982 (Funencodable_char_position, code_convert_region)
5983 (code_convert_string, code_convert_string_norecord)
5984 (Fset_coding_system_priority):
5985 * fileio.c (Finsert_file_contents):
5986 Use bool for booleans.
5987 * coding.h, lisp.h: Reflect above API changes.
5988 * coding.c: Remove unnecessary static function decls.
5989 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5990 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5991 not a boolean 'int', since callers never look at the return value.
5992 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5993 * coding.h (decoding_buffer_size, encoding_buffer_size)
5994 (emacs_mule_string_char): Remove unused extern decls.
5995 (struct iso_2022_spec, struct coding_system):
5996 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5997 (struct emacs_mule_spec): Remove unused field 'full_support'.
5998 All initializations removed.
5999 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6001 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6003 Fix spare memory change (Bug#12286).
6004 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6005 (valid_lisp_object_p): Likewise.
6007 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6009 * window.c (Fset_window_configuration): Record any window's old
6010 buffer if it's replaced (see Bug#8789). If the new current
6011 buffer doesn't appear in the selected window, go to its old
6014 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6016 Special MEM_TYPE_SPARE to denote reserved memory.
6017 * alloc.c (enum mem_type): New memory type.
6018 (refill_memory_reserve): Use new type for spare memory.
6019 This prevents live_cons_p and live_string_p from incorrect
6020 detection of uninitialized objects from spare memory as live.
6022 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6025 * Makefile.in (.PHONY): versioclean -> versionclean.
6027 Remove unused external symbols.
6028 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6029 * window.c (Qwindow_valid_p, decode_valid_window):
6030 Now static, not extern.
6031 * data.c (Qinterval): Remove; unused.
6032 (syms_of_data): Do not define 'interval'.
6033 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6034 * window.h (decode_valid_window):
6037 * character.c, charset.c, chartab.c: Use bool for booleans.
6038 * character.c (lisp_string_width, string_count_byte8)
6039 (string_escape_byte8):
6040 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6041 (load_charset_map_from_file, map_charset_chars)
6042 (Fdefine_charset_internal, define_charset_internal)
6043 (Fdeclare_equiv_charset, find_charsets_in_text)
6044 (Ffind_charset_region, char_charset, Fiso_charset):
6045 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6046 (sub_char_table_set, sub_char_table_set_range)
6047 (char_table_set_range, optimize_sub_char_table)
6048 (map_sub_char_table):
6049 Use bool for boolean.
6050 * character.c (str_to_unibyte): Omit last boolean argument; it was
6051 always 0. All callers changed.
6052 * character.h, charset.h: Adjust to match previous changes.
6053 * character.h (char_printable_p): Remove decl of nonexistent function.
6054 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6055 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6056 are all boolean, so make them single-bit bitfields.
6058 * lisp.h (ASET): Remove attempt to detect side effects.
6059 It was meant to be temporary and it often doesn't work,
6060 because when IDX has side effects the behavior of IDX==IDX
6061 is undefined. See Stefan Monnier in
6062 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6064 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6066 * lisp.h (functionp): New function (extracted from Ffunctionp).
6067 (FUNCTIONP): Use it.
6068 * eval.c (Ffunctionp): Use it.
6070 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6072 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6073 as that's faster and simpler than static storage. Don't bother
6074 with the g_main_context_query overhead if g_main_context_pending
6075 says no events are pending.
6076 (gfds, gfds_size): Remove these static vars.
6077 (xgselect_initialize): Remove; no longer needed.
6078 All uses and decls removed.
6080 * emacs.c (fatal_error_signal_hook): Remove.
6081 All uses removed. This leftover from old code was always 0.
6083 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6084 * casefiddle.c (casify_object, casify_region):
6085 * casetab.c (set_case_table):
6086 * category.c, category.h (word_boundary_p):
6087 * category.h (CHAR_HAS_CATEGORY):
6088 Use bool for booleans, instead of int.
6090 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6092 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6094 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6096 On assertion failure, print backtrace if available.
6097 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6098 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6099 * Makefile.in (LIB_EXECINFO): New macro.
6102 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6103 * bytecode.c (exec_byte_code):
6104 * callint.c (check_mark, Fcall_interactively):
6105 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6106 (getenv_internal, sync_process_alive, call_process_exited):
6107 * lisp.h (USE_SAFE_ALLOCA):
6108 Use bool for booleans, instead of int.
6109 * lisp.h, process.h: Adjust prototypes to match above changes.
6110 * callint.c (Fcall_interactively): Don't assume the mark's
6111 offset fits in 'int'.
6113 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6115 * buffer.c, buffer.h: Use bool for boolean.
6116 * buffer.c (reset_buffer_local_variables)
6117 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6118 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6119 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6120 (overlay_touches_p, overlay_strings, Foverlay_put)
6121 (report_overlay_modification, call_overlay_mod_hooks):
6122 (mmap_enlarge, mmap_set_vars):
6123 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6124 Use bool for booleans, instead of int.
6125 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6126 since the 1-or-0 return value is always ignored anyway.
6127 (mmap_initialized_p):
6128 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6129 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6131 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6133 * bidi.c: Use bool for boolean.
6134 This is a bit more readable, and makes the text segment of bidi.o
6135 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6136 Presumably it's faster too.
6137 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6139 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6140 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6141 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6142 (bidi_explicit_dir_char, bidi_level_of_next_char)
6143 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6144 Use bool for booleans, instead of int.
6145 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6146 (bidi_unshelve_cache): Adjust decls to match code.
6148 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6150 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6153 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6155 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6156 * atimer.h: Include <stdbool.h>.
6158 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6160 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6161 compile time tests instead of run time tests on systems that do
6163 (FRAME_MAC_P): Remove leftover from deleted code.
6164 * frame.c (syms_of_frame): Remove leftover from deleted code.
6166 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6168 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6170 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6172 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6173 Otherwise, the compiler complains about (A?B:C) where B is void
6174 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6175 (fontset_add): Return void, for FONTSET_ADD.
6177 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6179 * alloc.c: Use bool for booleans.
6180 (gc_in_progress, abort_on_gc)
6181 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6182 (dont_register_blocks) [GC_MALLOC_CHECK]:
6183 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6184 (check_string_bytes, make_specified_string, memory_full)
6185 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6186 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6187 (mark_stack, valid_pointer_p, make_pure_string)
6188 (Fgarbage_collect, survives_gc_p, gc_sweep):
6189 Use bool for booleans, instead of int.
6190 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6191 Remove unused local.
6192 * alloc.c (PURE_POINTER_P):
6193 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6194 * editfns.c (Fformat):
6195 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6197 * fns.c (sweep_weak_table):
6198 * lisp.h (suppress_checking, push_message, survives_gc_p)
6199 (make_pure_string, gc_in_progress, abort_on_gc):
6200 * lread.c (readchar, read1):
6201 * print.c (Fprin1_to_string):
6202 * xdisp.c (push_message):
6203 Use bool for booleans affected directly or indirectly by
6206 Make recently-introduced setters macros.
6207 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6208 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6209 (set_fontset_default, set_fontset_fallback): Rename from their
6210 upper-case counterparts, and make them functions rather than macros.
6211 This is more consistent with the other recently-introduced setters.
6212 These don't need to be inline, since they're local.
6214 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6216 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6217 the loop (Bug#12247).
6219 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6221 * lisp.h (vcopy): Use memcpy rather than our own loop.
6222 This fixes a performance regression introduced by the recent
6223 addition of vcopy. This means 'vcopy' will need to be modified
6224 for a copying collector, but that's OK. Also, tighten the
6225 checking in the assertion.
6227 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6229 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6230 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6231 non-base glyph for the width of the base character, according to
6232 what x_draw_composite_glyph_string_foreground expects.
6233 Generate WADJUST value according to composition_gstring_width's
6234 expectations, to produce correct width of the composed character.
6235 Reverse the sign of the DU offset produced by ScriptPlace.
6237 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6239 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6241 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6243 Avoid direct writes to contents member of struct Lisp_Vector.
6244 * lisp.h (vcopy): New function to copy data into vector.
6245 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6246 * fns.c (Ffillarray): Use ASET.
6247 * keyboard.c (timer_check_2): Use AREF and ASET.
6248 (append_tool_bar_item, Frecent_keys): Use vcopy.
6249 * lread.c (read_vector): Use ASET.
6250 * msdos.c (Frecent_doskeys): Use vcopy.
6251 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6252 (Finternal_merge_in_global_face): Use ASET and vcopy.
6253 * xfont.c (xfont_list_pattern): Likewise.
6255 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6257 * window.c (Fwindow_point): For the selected window always return
6258 the position of its buffer's point.
6259 (Fset_window_point): For the selected window always go in its
6260 buffer to the specified position.
6262 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6264 Setter macros for fontsets.
6265 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6266 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6267 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6270 2012-08-20 Glenn Morris <rgm@gnu.org>
6272 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6273 Don't assume that `ln -f' works.
6275 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6277 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6278 and later about non-assignments with no effect. See discussion at
6279 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6282 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6284 Inline setter functions for Lisp_Objects slots of struct specbinding.
6285 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6288 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6290 * window.c (select_window): Always make selected window's buffer
6293 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6295 Use AREF and ASET for docstrings of category tables.
6296 * category.h (CATEGORY_DOCSTRING): Use AREF.
6297 (SET_CATEGORY_DOCSTRING): Use ASET.
6298 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6300 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6302 Inline setter functions for hash table members.
6303 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6304 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6305 (set_hash_key_and_value, set_hash_index, set_hash_next)
6306 (set_hash_hash): New functions.
6307 * charset.c, fns.c: Adjust users.
6309 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6311 Inline getter and setter functions for per-buffer values.
6312 * buffer.h (per_buffer_default, set_per_buffer_default)
6313 (per_buffer_value, set_per_buffer_value): New functions.
6314 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6315 * buffer.c, data.c: Adjust users.
6317 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6319 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6321 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6323 Rely on <config.h> + <unistd.h> to declare 'environ',
6324 as gnulib does this if the system doesn't.
6325 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6326 Remove declaration. MS-Windows declares it on stdlib.h which is
6327 included by conf_post.h.
6328 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6329 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6330 * vm-limit.c: Include <unistd.h>, for 'environ'.
6332 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6333 (start_of_data): Remove decl; mem-limits.h provides it.
6335 * xdisp.c (handle_invisible_prop): Make it a bit faster
6336 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6338 2012-08-19 Chong Yidong <cyd@gnu.org>
6340 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6343 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6345 * .gdbinit: Use call instead of set when calling a function in the
6348 * data.c (set_internal): Don't use set_blv_found.
6349 (Fkill_local_variable): Likewise.
6351 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6353 * nsfont.m (ns_ascii_average_width): Ensure the string
6354 ascii_printable is initialized with a null-terminated character
6355 array. Otherwise, it can contain undesired extra characters.
6357 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6359 port new setting code to Sun C 5.8 2005/10/13
6360 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6361 Return void, not Lisp_Object. Otherwise, the compiler
6362 complains about (A?B:C) where B is void and C is Lisp_Object
6363 when compiling CHAR_TABLE_SET, due to the recent change to
6364 the API of sub_char_table_set_contents.
6366 2012-08-18 Chong Yidong <cyd@gnu.org>
6368 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6369 for the string case (Bug#3874).
6371 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6373 * buffer.h (BSET): Remove (Bug#12215).
6374 Replace all uses with calls to new setter functions.
6375 (bset_bidi_paragraph_direction, bset_case_canon_table)

7252 Remove unnecessary pointer casts.
7253 * alloc.c (record_xmalloc): New function.
7254 * lisp.h (record_xmalloc): New decl.
7255 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7256 more like a function. This is because the pointer cast is not
7257 needed. All uses changed.
7258 * print.c (print_string, print_error_message): Avoid length recalc.
7260 Improve fix for macroexp crash with debugging (Bug#12118).
7261 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7262 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7263 not supposed to be invoked from the garbage collector.

7265 (gc_aset): New function, which is like ASET but can be
7266 used in the garbage collector.

7295 with addition of handling of symlinks and support for 'lstat'.
7296 If possible, get file's attributes and security information by
7297 handle, not by name. Produce S_IFLNK bit for symlinks, when
7298 called from 'lstat'.
7299 (stat, lstat): New functions, call 'stat_worker'.
7300 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7301 symlinks when the underlying filesystem supports them.
7303 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7305 Fix macroexp crash on Windows with debugging (Bug#12118).
7306 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7307 checking subscripts; problem introduced with the recent
7308 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7309 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7310 since it's used in non-static inline functions now.
7312 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

7333 * composite.c (COMPOSITE_INLINE):
7334 * dispnew.c (DISPEXTERN_INLINE):
7335 * sysdep.c (SYSTIME_INLINE):

7339 (INLINE_HEADER_END): New macros.
7340 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7362 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7364 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7365 This how ASET and AREF are supposed to work, and makes
7366 it easier to think about future improvements. See
7367 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7368 * charset.h (set_charset_attr): New function.

7750 (w32_kbd_patch_key, key_event): Use the codepage returned by
7751 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

7783 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7784 enumeration constants, as PURE and HEAP are too general, and clash
7785 with other headers and sources, such as gmalloc.c and the
7786 MS-Windows system headers. All users changed.
7788 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7790 Revert last save_excursion_save and save_excursion_restore changes.
7791 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7804 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7805 arms of an 'if', not using conditional expressions; otherwise GDB
7806 complains about the types in the unevaluated arm when the argument
7807 is an integer literal.
7808 (xgetint): Simplify expression.
7809 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7810 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7811 Zaretskii in <http://bugs.gnu.org/12036#13>.
7812 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7813 needed now that we have gdb_make_enums_visible.
7814 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7815 (enum enum_USE_LSB_TAG):
7816 New enum types, packaging up enums that need to be exported to GDB.

7858 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7859 emacs.c, as this is a more-suitable home. Had this been done earlier
7860 the fix for 12036 would have avoided some of the problems noted in
7861 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7862 would have been more obvious.
7863 * emacs.c: Do not include <verify.h>; no longer needed.
7864 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7865 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7866 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

7871 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7872 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7873 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7874 not be usable in #if. This simplifies things.
7876 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7878 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7883 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7884 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7885 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7886 Adjust to changes in lisp.h and emacs.c, by using
7887 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7888 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7889 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7890 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7891 instead of gdb_valbits.
7892 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7893 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7894 instead of gdb_array_mark_flag.
7895 (xboolvector): Get size from $->size, not $->header.size.
7896 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7897 (xreload, hook-run, hookpost-run): Remove.
7898 * emacs.c: Include <verify.h>.
7899 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7900 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7902 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7903 (gdb_USE_LSB_TAG): New enum constants.
7904 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7905 Also define these as enum constants, so they're visible to GDB.
7906 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7907 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7908 as constants, so they're visible to GDB.

7911 Now enum constants, not macros, so they're visible to GDB.
7912 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7913 more convenient now. All uses changed.
7914 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7915 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7917 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7924 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7925 add argument, tune behavior, and adjust all callers.
7927 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7929 Use typedef for EMACS_INT, EMACS_UINT.
7930 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7931 than macros. This simplifies debugging in the usual case, since
7932 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7933 and it allows expressions involving EMACS_INT casts.
7934 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7936 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7946 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7948 Adjust buffer text indirection counters at the end of Fkill_buffer.
7949 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7950 buffer is definitely dead. This should really fix an issue reported
7951 by Christoph Scholtes again. (Bug#12007).
7952 (init_buffer_once): Initialize indirection counters of
7953 buffer_defaults and buffer_local_symbols (for sanity and safety).
7955 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7957 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7958 and continuation glyphs on tooltip frames, leave them at zero.

7986 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7988 Swap buffer text indirection counters in Fbuffer_swap_text.
7989 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7990 This avoids crash reported by Christoph Scholtes at
7991 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7993 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7995 * nsmenu.m (Popdown_data): New struct.
7996 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7998 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7999 (initWithContentRect): Make imgView and contentView non-static
8000 and autorelease them. Also autorelease img and matrix (Bug#12005).
8001 (dealloc): Remove (Bug#12005).
8003 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8005 Adjust consing_since_gc when objects are explicitly freed.

8018 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8020 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8021 as it's limited by the amount of memory, not by INT_MAX.
8023 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8025 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8026 in special-event-map. See the discussion at

8085 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8086 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8087 Adjust users accordingly.
8088 * font.h (font_open_by_name): Adjust prototype.

8107 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8108 'for_each_per_buffer_object_at'.
8109 All uses changed. It's better to use upper-case for macros that

8111 that they're special.
8113 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
8115 * alloc.c (Fgarbage_collect): Tweak docstring.

8749 * s/aix4-2.h (unix): Remove; no longer needed.
8751 EMACS_TIME simplification (Bug#11875).
8752 This replaces macros (which typically do not work in GDB)
8753 with functions, typedefs and enums, making the code easier to debug.
8754 The functional style also makes code easier to read and maintain.
8755 * systime.h: Include <sys/time.h> on all hosts, not just if
8756 WINDOWSNT, since 'struct timeval' is needed in general.
8757 (EMACS_TIME): Now a typedef, not a macro.

8768 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8769 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8770 not functions. All uses rewritten to use the following, respectively:
8771 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8772 (add_emacs_time, sub_emacs_time): New functions.
8773 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8774 * fileio.c (Fcopy_file):
8775 * xterm.c (XTflash): Get the current time closer to when it's used.
8776 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8790 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8791 (menu_separator_name_p):
8792 * nsmenu.m (ns_update_menubar):
8793 Prefer memcmp to strncmp when either will do.
8794 * nsterm.m: Include <ftoastr.h>.
8796 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8797 Prefer snprintf to strncpy.
8798 * nsterm.m (ns_term_init):
8799 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8800 * nsterm.m (ns_term_init):
8801 Avoid the need for strncpy, by using build_string or
8802 make_unibyte_string directly. Use dtoastr, not snprintf.
8803 * process.c (Fmake_network_process): Diagnose service names that
8804 are too long, rather than silently truncating them or creating
8805 non-null-terminated names.
8806 (Fnetwork_interface_info): Likewise, for interface names.
8807 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8808 Prefer sprintf to strncat.

8812 2012-07-10 Glenn Morris <rgm@gnu.org>
8814 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8815 Clarify fallback case.
8817 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

8821 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8822 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8823 where argument type is known to be a Lisp_Cons.

8835 Optimize pure C strings initialization.
8836 * lisp.h (make_pure_string): Fix prototype.
8837 (build_pure_c_string): New function, defined as static inline. This
8838 provides a better opportunity to optimize away calls to strlen when
8839 the function is called with compile-time constant argument.
8840 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8841 argument, adjust users accordingly. Use build_pure_c_string where

8844 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8845 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8847 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8849 Avoid calls to strlen in miscellaneous functions.
8850 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8851 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8852 * lread.c (openp): Likewise.
8854 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8856 Avoid calls to strlen in path processing functions.
8857 * fileio.c (file_name_as_directory): Add comment. Change to add
8858 srclen argument and return the length of result. Adjust users
8860 (directory_file_name): Fix comment. Change to add srclen argument,

8874 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8875 We include usg5-4-common.h, which defines them both.
8877 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8878 O_RDONLY already includes it).
8880 Stop ns builds setting the EMACSLOADPATH environment variable.
8881 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8882 Now it does not set EMACSLOADPATH, just returns the load-path string.
8883 * nsterm.h: Update accordingly.
8884 * lread.c [HAVE_NS]: Include nsterm.h.
8885 (init_lread) [HAVE_NS]: Use ns_load_path.
8886 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8888 2012-07-09 Glenn Morris <rgm@gnu.org>
8890 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8891 since the included bsd-common.h does so.
8893 Stop ns builds setting the EMACSPATH environment variable.
8894 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8895 (ns_init_paths): Do not set EMACSPATH.
8896 * nsterm.h (ns_exec_path): Add it.
8897 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8900 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8902 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8904 * process.c (wait_reading_process_output): 'waitchannels' was unset
8905 when read_kbd || !NILP (wait_for_cell); fix this.
8907 Add GCC-style 'const' attribute to functions that can use it.
8908 * character.h (char_resolve_modifier_mask):
8909 * keyboard.h (make_ctrl_char):
8910 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8921 Minor improvements to make_formatted_string.
8922 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8923 where int is good enough, as vsprintf returns an int.
8924 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8926 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>

8955 Move marker debugging code under MARKER_DEBUG.
8956 * marker.c (MARKER_DEBUG): Move marker debugging code under
8957 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8958 for bootstrap with --enable-checking (~3x slowdown reported
8959 by Juanma Barranquero <lekktu@gmail.com>).
8960 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8962 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8964 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8965 See <http://bugs.gnu.org/11825#29>.

8969 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8970 has no font, use the frame's font. (Bug#11813)
8971 (display_line): Add commentary about displaying truncation glyphs
8973 (produce_special_glyphs): Move here from term.c.
8975 * term.c (produce_special_glyphs): Move to xdisp.c.
8977 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8980 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8982 * xdisp.c (display_line): Avoid warning about implicit declaration
8985 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8987 * lisp.h: Remove empty conditional.
8989 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8991 * lread.c (load_path_check): Now static.
8993 Fix some minor --with-ns problems found by static checking.
8994 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8995 (x_set_font) [!HAVE_X_WINDOWS]:
8996 * image.c (xpm_load_image) [HAVE_NS]:
8997 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8998 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8999 Remove unused local.
9000 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9001 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.

9008 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9010 2012-07-07 Glenn Morris <rgm@gnu.org>
9012 * lread.c (load_path_check): New function, split from init_lread.
9013 (init_lread): Reorganize. Motivation:
9014 If EMACSLOADPATH is set, check/warn about that rather than the
9015 defaults, which we are not going to use. Hence we can remove
9016 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9017 Don't warn if site-lisp directories are missing.
9018 If not installed, start from a blank load-path, since
9019 PATH_LOADSEARCH refers to the eventual installation directories.
9021 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9023 Support truncation and continuation glyphs on GUI frames, when
9024 fringes are disabled. (Bug#11832)
9025 * xdisp.c (init_iterator): Get dimensions of truncation and
9026 continuation glyphs even if on GUI frames.
9027 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9028 or both, are absent.
9029 (start_display, move_it_in_display_line_to): Handle the case of a
9030 GUI frame without a fringe to display continuation or truncation
9032 (insert_left_trunc_glyphs): Support GUI frames: make sure
9033 truncation glyphs overwrite enough glyphs from the current line to
9034 have sufficient space in pixels.
9035 (display_line): Support truncation and continuation glyphs on GUI
9036 frames. If some spare pixels are left on the line after inserting
9037 the truncation glyphs, fill that space with a stretch glyph of a
9038 suitably computed width.
9040 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9041 produce_glyphs, to support GUI sessions.
9043 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9045 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9047 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9049 Do not require float-time's arg to fit in time_t (Bug#11825).
9050 This works better on hosts where time_t is unsigned, and where
9051 float-time is applied to the (negative) difference between two times.
9052 * editfns.c (decode_time_components): Last arg is now double *,
9053 not int *, and means to store all the result as a double, without
9054 worrying about whether the seconds part fits in time_t.
9055 All callers changed.
9056 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9057 All callers changed.
9058 (Ffloat_time): Do not fail merely because the specified time falls
9059 outside of time_t range.
9061 2012-07-07 Glenn Morris <rgm@gnu.org>
9063 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9078 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9079 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.

9083 * xfont.c (compare_font_names): Redo to omit the need for casts.
9085 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9087 * xfns.c (Fx_change_window_property): Doc fix.
9088 * w32fns.c (Fx_change_window_property): Doc fix.
9090 * w32fns.c (Fx_window_property): Accept the same arguments as the
9091 X Windows version. Doc fix.
9092 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9094 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9095 Eli Zaretskii <eliz@gnu.org>
9097 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9098 Windows-specific code from nt/config.nt moved here.
9099 Obsolete settings removed.
9101 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9103 * process.c: Avoid unnecessary calls to gettime.
9104 (wait_reading_process_output): Don't get the time of day
9105 when gobbling data immediately and not waiting, as there's no need
9106 for it in that case. This removes a FIXME.
9108 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9110 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9111 is defined (Bug#11768).
9113 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9115 Fix marker debugging code.
9116 * marker.c (byte_char_debug_check): Do not perform the check
9117 if buffer is not multibyte.
9118 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9119 Call byte_char_debug_check with correct arguments.
9121 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9123 Compile marker debugging code only if ENABLE_CHECKING is defined.
9124 * marker.c (byte_char_debug_check, count_markers):
9125 Use only if ENABLE_CHECKING is defined.
9126 (byte_debug_flag): Remove.
9127 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9128 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9130 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9132 Avoid code repetition in marker-related functions.
9133 * marker.c (attach_marker): New function.
9134 (Fset_marker, set_marker_restricted, set_marker_both)
9135 (set_marker_restricted_both): Use it.
9136 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9137 Consistently rename charno to charpos.
9138 (marker_position): Add eassert.
9139 (marker_byte_position): Convert to eassert.

9151 * lisp.h (build_marker): New prototype.
9152 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9153 * composite.c (autocmp_chars): Likewise.
9154 * editfns.c (buildmark): Remove.
9155 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9156 (save_restriction_save): Use build_marker.
9157 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9158 * window.c (save_window_save): Likewise.
9160 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9162 Do not use Fdelete_overlay in delete_all_overlays
9163 to avoid redundant calls to unchain_overlay.
9164 * buffer.c (drop_overlay): New function.
9165 (delete_all_overlays, Fdelete_overlay): Use it.
9166 * minibuf.c (get_minibuffer): Fix comment.
9168 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9170 Port to OpenBSD 5.1 amd64.
9171 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9172 This is needed for OpenBSD, and should be harmless on all BSD systems.
9173 Also, include <sys/sysctl.h>, as it should be available on all
9174 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9175 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9176 use p_pid member, not kp_proc.pid.
9178 2012-07-06 Glenn Morris <rgm@gnu.org>
9180 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9182 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9184 More xmalloc and related cleanup.

9193 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9195 Omit needless casts involving void * pointers and allocation.
9196 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9197 as the former is more robust if P's type is changed.
9198 Prefer xzalloc to xmalloc + memset 0.
9199 Simplify malloc-or-realloc to realloc.
9200 Don't worry about xmalloc returning a null pointer.
9201 Prefer xstrdup to xmalloc + strcpy.
9202 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9204 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9205 alloca of a constant.
9207 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9209 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9210 hscroll is larger than the line width. Fixes long and futile
9211 looping inside extend_face_to_end_of_line (on a TTY) producing
9212 glyphs that are not needed and thrown away.
9214 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9216 * marker.c (set_marker_restricted_both): Simplify by using

9228 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9229 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9230 followed by gtk_box_set_homogeneous (Bug#11768).
9231 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9232 (update_theme_scrollbar_width, xg_create_scroll_bar):
9233 Use gtk_scrollbar_new (Bug#11768).
9234 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9235 (is_box_type): New function (Bug#11768).

9242 * xdisp.c (window_hscroll_limited): New function.
9243 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9244 coordinates when window's hscroll is set to insanely large
9247 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9249 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9311 Problem reported by Troels Nielsen in
9312 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

9316 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9317 This should be fixed in a better way; see Eli Zaretskii in
9318 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9319 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9321 * fileio.c (time_error_value): Rename from special_mtime.
9322 The old name's problems were noted by Eli Zaretskii in
9323 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9325 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9326 This variable's comment says Emacs needs at least one GDB-visible
9327 symbol of type enum pvec_type, to work around GDB problems.
9328 The symbol's value doesn't matter.
9330 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9331 that causes compilation to fail on pre-C99 compilers.
9333 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9335 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9347 * lisp.h (enum pvec_type): Use fewer bits.
9348 (PSEUDOVECTOR_SIZE_BITS): New constant.
9349 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9350 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9351 change in pvec_type.

9358 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9359 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9360 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9361 abusing vector->header.next.nbytes.
9362 (live_vector_p): Use PVEC_TYPE.
9363 (mark_object): Adapt code to extract pvectype. Use switch.
9365 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9367 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9368 Tighten new eassert a bit.
9370 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9372 Fix compilation with --enable-gcc-warnings and -O1
9374 * doprnt.c (doprnt): Change type of tem to int, initialize
9375 to avoid compiler warning. Add eassert.
9376 * search.c (simple_search): Initialize match_byte to avoid
9377 compiler warning. Add eassert.
9379 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9381 Avoid weird behavior with large horizontal scrolls.
9382 Without this change, for example, large hscroll values would
9383 mess up Emacs's display on Fedora 15 x86, presumably due to
9384 overflows in int calculations in the display code.
9385 Also, if buffers had long lines, Emacs would freeze.
9386 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9387 (set_window_hscroll): New function, containing the old guts of
9388 Fset_window_hscroll. Return the clipped value.
9389 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9390 This avoids the need to check against PTRDIFF_MAX.
9392 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9394 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

9398 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9400 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9401 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9402 since GCC 4.4.6 issues a bogus warning for them.
9404 Fix bugs in file timestamp newness comparisons.
9405 * fileio.c (Ffile_newer_than_file_p):
9406 * lread.c (Fload): Use full timestamp resolution of files,
9407 not just the 1-second resolution, so that files that are only
9408 slightly newer still count as newer.
9409 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9410 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9412 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9414 * fileio.c: Improve handling of file time marker. (Bug#11852)
9415 (special_mtime): New function.

9417 Use it to set special mtime values consistently.
9419 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9421 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9422 marker for non-existing file. (Bug#11852)
9424 2012-07-03 Glenn Morris <rgm@gnu.org>
9426 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9427 and did not make it into globals.h).
9429 2012-07-03 Tom Tromey <tromey@redhat.com>

9469 * lisp.h (Frandom): Make it visible to C.
9470 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9471 buffer for invisible buffers. (Bug#1229)

9475 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9476 values which aren't power of 2.
9477 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9478 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9481 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9483 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9485 * alloc.c (mark_object): Revert part of last patch to use `switch'.

9489 * alloc.c (allocate_vector_block): Remove redundant
9490 calls to mallopt if DOUG_LEA_MALLOC is defined.
9491 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9492 avoid calls to mallopt if zero_vector is returned.
9494 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9496 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9497 is enabled, avoid dereferencing NULL current_sblock if
9500 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9502 Cleanup basic buffer management.
9503 * buffer.h (struct buffer): Change layout to use generic vector
9504 marking code. Fix some comments. Change type of 'clip_changed'
9505 to bitfield. Remove unused #ifndef old.
9506 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9507 (GET_OVERLAYS_AT): Fix indentation.
9508 (for_each_per_buffer_object_at): New macro.
9509 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
9510 (Fbuffer_local_variables): Use it.
9511 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9512 * alloc.c (allocate_buffer): Adjust to match new layout of
9513 struct buffer. Fix comment.
9514 (mark_overlay): New function.
9515 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9516 Lisp area of struct buffer.
9517 (mark_object): Use it. Adjust marking of misc objects
9518 and related comments.
9520 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9522 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9523 wrapper that is not needed because the wrapped code is a no-op (zero
9524 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9525 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9527 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9529 * alloc.c (mark_buffer): Simplify. Remove prototype.
9530 (mark_object): Add comment. Reorganize marking of vector-like
9531 objects. Use CHECK_LIVE for all vector-like objects except buffers
9532 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9533 Avoid redundant calls to mark_vectorlike for bool vectors.
9535 2012-06-30 Glenn Morris <rgm@gnu.org>
9537 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9539 * epaths.in (PATH_SITELOADSEARCH): New.
9540 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9541 This is rather than relying on --enable-locallisppath elements
9542 having "site-lisp" in their names. (Bug#10208#25, 11658)
9544 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9546 * w32proc.c (sys_select): Accept and ignore one more argument.
9548 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9550 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9551 (pselect) [!MS_DOS]: Redirect to sys_select.
9553 * sysdep.c: Don't include dos.h and dosfns.h.
9555 * process.c (sys_select):
9556 * msdos.c (sys_select): Accept one more argument and ignore it.
9558 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9559 adapt data types and code to that.
9562 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9563 which clashes with the gnulib function of the same name.
9565 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9567 * font.c (font_style_to_value, font_style_symbolic)
9568 (font_prop_validate_style): Add type checks for values in
9571 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9573 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9576 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9578 * xdisp.c (try_window_id): Undo last change.
9580 * w32.c (getwd): Adjust commentary about startup_dir.
9581 (init_environment): Always call sys_access, even in non-MSVC
9582 builds. Don't chdir to the directory of the Emacs executable.
9583 This undoes code from 1997 which was justified by the need to
9584 "avoid conflicts when removing and renaming directories". But its
9585 downside was that every relative file name was being interpreted
9586 relative to the directory of the Emacs executable, which can never
9587 be TRT. In particular, it broke sys_access when called with
9588 relative file names.
9589 (sys_access): Map GetLastError to errno.
9591 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9593 * window.h (struct window): Change type of 'fringes_outside_margins'
9594 to bitfield. Fix comment. Adjust users accordingly.
9595 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9597 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9600 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9602 * gnutls.c (emacs_gnutls_handshake):
9603 Add QUIT to make the loop interruptible.
9605 2012-06-29 Glenn Morris <rgm@gnu.org>
9607 * charset.c (init_charset): Make lack of etc/charsets fatal.
9609 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9611 * editfns.c (region_limit): Fix type mismatch.
9613 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9615 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9616 undefined. Convert from xassert to eassert.
9617 * nsmenu.m: Convert from xassert to eassert.
9618 * nsterm.m: Likewise.
9620 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9622 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9624 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9626 Avoid integer overflow on scroll-left and scroll-right.
9627 * window.c (HSCROLL_MAX): New macro.
9628 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9629 overflow when requested scroll falls outside ptrdiff_t range.
9631 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9633 * window.h (struct window): Change type of 'hscroll',
9634 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9635 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9636 Adjust users accordingly.
9637 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9638 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9639 from EMACS_INT to ptrdiff_t.
9640 (make_window): Omit redundant initialization.
9642 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9644 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9646 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9648 * window.h (struct window): Change type of 'use_time' and
9649 'sequence_number' from Lisp_Object to int.

9658 enabled with --enable-checking=[all,glyphs] configure option.
9659 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9660 adjust comments accordingly.

9709 * alloc.c (allocate_string_data): Remove dead code.
9710 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
9711 avoid GCC warning about unused macro.
9713 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9715 * alloc.c (allocate_string): Omit intervals initialization.
9716 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9717 as in make_pure_string and make_pure_c_string.
9719 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9721 * alloc.c (allocate_string): Fix last change.
9723 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9748 2012-06-26 Eli Zaretskii <eliz@gnu.org>
9750 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
9751 _stricmp and _strnicmp.
9752 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.

9769 * term.c (delete_tty): Remove redundant call to memset.
9771 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9773 * alloc.c: Remove build_string.
9774 * lisp.h: Define build_string as static inline. This provides
9775 a better opportunity to optimize away calls to strlen when the
9776 function is called with compile-time constant argument.
9777 * image.c (imagemagick_error): Convert to build_string.
9778 * w32proc.c (sys_spawnve): Likewise.
9779 * xterm.c (x_term_init): Likewise.
9781 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9783 Use sprintf return value instead of invoking strlen on result.
9784 In the old days this wasn't portable, since some sprintf
9785 implementations returned char *. But they died out years ago and
9786 Emacs already assumes sprintf returns int.
9787 Similarly for float_to_string.
9788 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9789 * ccl.c (ccl_driver):
9790 * character.c (string_escape_byte8):

9793 * print.c (print_object):
9794 * xdisp.c (message_dolog):
9795 * xfns.c (syms_of_xfns):
9796 Use sprintf or float_to_string result to avoid need to call strlen.
9797 * data.c (Fnumber_to_string):
9798 Use make_unibyte_string, since the string must be ASCII.
9799 * lisp.h, print.c (float_to_string): Now returns int length.
9800 * term.c (produce_glyphless_glyph):
9801 Use sprintf result rather than recomputing it.
9803 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9804 * Makefile.in (ALL_CFLAGS):
9805 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9806 * gmalloc.c, regex.c: Include <config.h> unconditionally.

9810 * dispextern.h (xstrcasecmp): Define to library function
9811 strcasecmp if available.
9812 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
9814 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
9816 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

9827 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9829 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9830 sprintf already null-terminates its output.
9832 * xfns.c (x_window): Remove redundant cast.
9834 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9836 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9837 `const char *' to `char *' to avoid compiler warning.
9839 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9841 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9842 instead of truncating it to 63 (admittedly a generous limit).
9844 * process.c: Fix spelling and caps in comments.
9846 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9848 * emacs.c (setpgrp): Remove definition, unused.

9858 (SYSTIME_H): Add nt/inc/sys/time.h.
9860 * systime.h [WINDOWSNT]: Include sys/time.h.
9862 * s/ms-w32.h (struct timespec): Definition moved from
9863 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
9865 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

9893 No need for separate decl merely because of _Noreturn.
9894 * sound.c (sound_warning, parse_sound):
9895 Remove unnecessary forward decls.
9897 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9899 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
9900 * lisp.h (WAIT_READING_MAX): New macro.
9901 * dispnew.c (Fsleep_for, sit_for):
9902 * keyboard.c (kbd_buffer_get_event):
9903 * process.c (Faccept_process_output):
9904 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9905 This improves on the previous patch, which introduced a bug
9906 when time_t is unsigned and as wide as intmax_t.
9907 See <http://bugs.gnu.org/9000#51>.
9909 2012-06-23 Eli Zaretskii <eliz@gnu.org>

9914 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
9916 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
9918 * makefile.w32-in: Update dependencies.
9920 * w32.c (ltime): Add return type and declare static.
9921 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
9923 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9925 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9926 Privately reported by Herbert J. Skuhra.
9927 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9929 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9930 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9932 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9934 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9935 last argument of make_unibyte_string.
9937 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9938 language ID in the event parameters.
9940 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9941 event.code, not the obscure "character set ID".
9943 2012-06-23 Chong Yidong <cyd@gnu.org>
9945 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9947 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9949 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
9950 * w32.c (fdutimens): New function.
9952 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
9954 * s/ms-w32.h (pselect): Redirect to sys_select.
9956 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
9958 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
9959 in the logic of incrementing and decrementing the value of
9960 use_relocatable_buffers.
9962 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9964 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9965 Privately reported by Herbert J. Skuhra.
9966 [__FreeBSD__]: Remove "*/" typo after "#include".
9967 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
9968 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.

9970 Don't assume EMACS_TIME and struct timeval are the same type.
9972 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9974 Support higher-resolution time stamps (Bug#9000).
9975 The time stamps are only nanosecond-resolution at the C level,
9976 since that's the best that any real-world system supports now.
9977 But they are picosecond-resolution at the Lisp level, as that's
9978 easy, and leaves room for future OS improvements.
9980 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9983 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9984 Don't get current time unless it's needed.
9986 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9987 now provides it if it's absent.
9988 (start_atimer): Port to higher-res time stamps.
9989 Check for time stamp overflow. Don't get current time more

10043 (timer_check_2): Use it.
10045 * nsterm.m (select_timeout, timeval_subtract): Remove.
10046 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10047 as they're a bit more accurate and handle overflow better.

10049 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10050 * nsterm.h (ns_select): Adjust prototype.

10069 (Faccept_process_output, wait_reading_process_output):
10070 Check for time stamp overflow. Do not assume time_t is signed.
10071 (select_wrapper): Remove; we now use pselect.
10072 (Fprocess_attributes): Now generates ns-resolution time stamps.
10074 * sysdep.c: Include utimens.h. Don't include utime.h
10075 or worry about struct utimbuf; gnulib does that for us now.
10076 (gettimeofday): Remove; gnulib provides a substitute.
10077 (make_timeval): New function.
10078 (set_file_times): Now sets ns-resolution time stamps.
10079 New arg FD; all uses changed.

10082 Now returns ns-resolution time stamp. All uses changed.
10083 Check for time stamp overflow.

10086 provides a substitute now.
10088 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10089 since it guarantees struct timespec.
10090 (EMACS_TIME): Now struct timespec, so that we can support
10091 ns-resolution time stamps.
10092 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10093 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10094 (EMACS_USECS): Remove.
10095 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10096 so multiply the arg by 1000 before storing it.
10097 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10099 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

10106 (make_timeval, make_lisp_time, decode_time_components): New decls.
10107 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10108 that it mishandled time_t overflow. You can't compare by subtracting!
10109 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10110 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

10128 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10129 for compatibility with pselect. Support ns-resolution time stamps.

10138 (timeval_subtract): Remove; no longer needed.
10139 (XTflash, XTring_bell, x_wait_for_event):
10140 Port to ns-resolution time stamps. Don't assume time_t is signed.

10146 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10148 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10149 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10150 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10151 staticidx goes up to 1597 out of 1600 = 0x640.)
10153 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10155 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

10201 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10202 gets killed during executing of this function (Bug#11665).
10203 Try to always return Qt when the buffer has been actually killed.
10204 (Vkill_buffer_query_functions): In doc-string say that functions
10205 run by this hook should not change the current buffer.

10229 * lisp.h (eassert): Assume C89 or later.
10230 This removes the need for CHECK.
10231 (CHECK): Remove. Its comments about always evaluating its
10232 argument were confusing, as 'eassert' typically does not evaluate
10235 * coding.c (produce_chars): Use ptrdiff_t, not int.
10237 * xterm.c (x_draw_underwave): Check for integer overflow.
10238 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10425 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10426 Use an inline function on all platforms when using the union type,

10430 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
10431 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

10569 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10571 * doprnt.c (doprnt): Truncate multibyte char correctly.
10572 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10573 would mishandle a string argument "Xc" if X was a multibyte
10574 character of length 2: it would truncate after X's first byte
10575 rather than including all of X.
10577 2012-06-06 Chong Yidong <cyd@gnu.org>
10579 * buffer.c (word_wrap): Doc fix.

10626 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10628 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10629 Convert pctcpu and pctmem to Lisp float properly.
10630 Let the compiler fold better, as 100.0/0x8000 is exact.
10632 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10634 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10637 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

10641 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10643 For a 'struct window', replace some Lisp_Object fields to
10644 bitfields where appropriate, remove unused fields.
10645 * window.h (struct window): Remove unused 'last_mark_x' and
10646 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10647 change its type from Lisp_Object to bitfield.
10648 Change type of 'force_start', 'optional_new_start',
10649 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10650 fields from Lisp_Object to bitfield. Adjust users accordingly.
10652 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10654 Pacify gcc -Wdouble-precision when using Xaw.
10655 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10656 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10657 Use 'float' consistently, rather than 'float' in most places
10658 and 'double' in a couple of places.
10660 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10662 * xdisp.c (handle_stop): Detect whether we have overlay strings
10663 loaded by testing it->current.overlay_string_index to be
10664 non-negative, instead of checking whether n_overlay_strings is
10665 positive. (Bug#11587)
10667 2012-05-31 Chong Yidong <cyd@gnu.org>
10669 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10673 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10675 * search.c (search_buffer): Remove calls to
10676 r_alloc_inhibit_buffer_relocation, as it is now called by
10677 maybe_unify_char, which was the cause of relocation of buffer text
10680 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10682 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10683 for the duration of call to load_charset, to avoid problems with
10684 callers of maybe_unify_char that access buffer text through C
10687 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10688 decrement the inhibition flag, instead of just setting or
10691 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10693 Remove obsolete '#define static' cruft.
10694 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10695 This #undef was "temporary" in 2000; it is no longer needed
10696 now that '#define static' has gone away.
10697 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10698 (gray_bitmap_bits): Remove; no longer needed.
10699 All uses replaced with definiens.

10707 Define only on platforms that need it.
10708 * emacs.c: Include <sys/gmon.h> when profiling.

10710 (__executable_start): Remove decl, since lisp.h does it now.
10711 (safe_bcopy): Remove decl; no longer has that name.
10712 (main): Coalesce #if into single bit of code, for simplicity.
10713 Cast pointers to uintptr_t, since standard libraries want integers
10715 * lisp.h (__executable_start): New decl.
10717 2012-05-31 Glenn Morris <rgm@gnu.org>
10719 * image.c (Fimagemagick_types): Doc fix.

10742 Do not create empty overlays with the evaporate property (Bug#9642).
10743 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10744 Bug#9642, but explicitly check that the buffer the overlay would
10745 be moved to is live and rearrange lines to make sure that errors
10746 will not put the overlay in an inconsistent state.
10747 (Fdelete_overlay): Cosmetics.
10749 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10751 * w32term.c (my_bring_window_to_top): New function.
10752 (x_raise_frame): Use handle returned by DeferWindowPos, which
10753 could be different from the original one.

10766 This avoids undefined behavior that might cause the eassert
10767 to not catch an out-of-range value.
10769 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10771 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

10785 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10786 Only r_alloc_inhibit_buffer_relocation needed to be added;
10787 the others were already declared.
10789 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10790 before checking whether it's out of range. Put the check inside
10792 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10794 2012-05-27 Ken Brown <kbrown@cornell.edu>

10801 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10802 defined on ralloc.c.
10804 * buffer.c [REL_ALLOC]: Remove prototypes of

10806 they are now on lisp.h.
10808 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10810 * search.c (search_buffer): Use it to inhibit relocation of buffer
10811 text while re_search_2 is doing its job, because re_search_2 is
10812 passed C pointers to buffer text. (Bug#11519)
10814 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10815 Update value to 24.
10817 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10818 state after an additional call to move_it_in_display_line_to, keep
10819 the values of it->max_ascent and it->max_descent found for the
10821 (pos_visible_p): Revert the comparison against bottom_y to what it
10822 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10825 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10827 Fix coding-related core dumps with gcc -ftrapv.
10828 The code was computing A - B, where A and B are pointers, and B is
10829 random garbage. This can lead to core dumps on platforms that
10830 have special pointer registers, and it also leads to core dumps on
10831 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10832 A - B only when B is initialized properly.
10833 * coding.c (coding_set_source, coding_set_destination): Return void.
10834 (coding_change_source, coding_change_destinations): New functions,
10835 with the old behaviors of coding_set_source and coding_set_destination.

10846 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10848 * w32console.c: Include window.h.
10849 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10851 (initialize_w32_display): Initialize mouse-highlight data.
10853 * w32inevt.c: Include termchar.h and window.h.
10854 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10855 moves, call note_mouse_highlight. If help_echo changed, call
10856 gen_help_event to produce help-echo message in the echo area.
10857 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10860 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10862 * lread.c (read1): Simplify slightly to avoid an overflow warning
10863 with GCC 4.7.0 on x86-64.
10865 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10867 * bidi.c (bidi_mirror_char): Revert last change: an int is
10868 definitely wide enough here.

10877 (make_unibyte_string, make_multibyte_string)
10878 (make_string_from_bytes, make_specified_string)
10879 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10880 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10882 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10883 (allocate_pseudovector):
10884 Use int, not EMACS_INT, where int is wide enough.
10885 (inhibit_garbage_collection, Fgarbage_collect):

10904 (Foverlay_recenter, last_overlay_modification_hooks_used)
10905 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10906 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10907 (validate_region): Omit unnecessary test for b <= e,
10908 since that's guaranteed by the previous test.
10909 (adjust_overlays_for_delete): Avoid pos + length overflow.
10910 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10911 (report_overlay_modification):
10912 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10913 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10914 Omit pointer cast, which isn't needed anyway, and doesn't work
10915 after the EMACS_INT -> ptrdiff_t change.
10916 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10917 * buffer.h: Adjust decls to match defn changes elsewhere.

10922 not int, to avoid needless 32-bit limit on 64-bit hosts.
10923 (exec_byte_code): Use tighter memory-full test, one that checks
10924 for alloca overflow. Don't compute the address of the object just
10925 before an array, as that's not portable. Use EMACS_INT, not
10926 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10927 * callint.c (Fcall_interactively):
10928 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10929 * callproc.c (call_process_kill, Fcall_process):
10930 Don't assume pid_t fits into an Emacs fixnum.

10940 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10941 (casify_object): Avoid integer overflow when overallocating buffer.
10942 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10943 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.

10945 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10946 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

10950 For CCL_MapSingle, check that content and value are in int range.
10951 (ccl_driver, Fregister_code_conversion_map):
10952 Check that Vcode_version_map_vector is a vector.
10953 (resolve_symbol_ccl_program): Check that vector header is in range.
10954 Always copy the vector, so that we can check its contents reliably
10955 now rather than having to recheck each instruction as it's being
10956 executed. Check that vector words fit in 'int'.
10957 (ccl_get_compiled_code, Fregister_ccl_program)
10958 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10959 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

10961 contents are in range.
10962 (Fccl_execute_on_string): Check that status is in range.
10963 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10964 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10965 Accept and return EMACS_INT, not int, because callers can pass values
10966 out of 'int' range.

10972 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10973 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10974 avoid mishandling large integers.

10983 Remove now-unnecessary CHECK_NATNUMs.
10984 (Fdefine_charset_internal): Check ranges here, more carefully.
10985 Don't rely on undefined behavior with signed left shift overflow.
10986 Don't assume unsigned int fits into fixnum, or that fixnum fits
10987 into unsigned int. Don't require max_code to be a valid fixnum;
10988 that's not true for gb10830 4-byte on a 32-bit host. Allow
10989 invalid_code to be a cons, for the same reason. Require code_offset
10990 to be a character. Avoid int overflow if max_char is close
10992 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10993 this is intended anyway and avoids some undefined behavior.
10994 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10995 INDEX_TO_CODE_POINT, as that's what it expects.
10996 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10997 * charset.h (DECODE_CHAR): Return int, not unsigned;
10998 this is what was intended anyway, and it avoids undefined behavior.
10999 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11000 integer-overflow issues.
11001 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11002 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11003 where the argument is EMACS_INT, and this behavior is not intended.
11004 * chartab.c (Fmake_char_table, Fset_char_table_range)
11005 (uniprop_get_decoder, uniprop_get_encoder):
11006 Don't assume fixnum fits in int.
11007 * cmds.c (move_point): New function, that does the gist of
11008 Fforward_char and Fbackward_char, but does so while checking
11009 for integer overflow more accurately.
11010 (Fforward_char, Fbackward_char): Use it.
11011 (Fforward_line, Fend_of_line, internal_self_insert)
11012 (internal_self_insert):
11013 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11782 (Fword_search_forward, Fword_search_backward_lax)
11783 (Fword_search_forward_lax): Move functions to isearch.el

11786 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11788 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11790 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11792 * lread.c (init_obarray): Declare Qt and Qnil as special.
11794 2012-05-14 Glenn Morris <rgm@gnu.org>
11796 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11797 Put "libexec" before "bin", for the sake of init_callproc_1.
11799 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11801 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11803 * unexaix.c: Port to more-recent AIX compilers.
11804 (report_error, report_error_1, make_hdr, copy_sym)
11805 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11806 Make arguments const char *, not char *, to avoid violations of C
11807 standard and to fix some AIX warnings reported by Gilles Pion.
11809 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11811 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11812 already have overlays loaded.
11813 (handle_single_display_spec): Before returning without displaying
11814 fringe bitmap, synchronize the bidi iterator with the main display
11815 iterator, by calling iterate_out_of_display_property.
11816 (iterate_out_of_display_property): Detect buffer iteration by
11817 testing that it->string is a Lisp string.
11818 (get_next_display_element): When the current object is exhausted,
11819 and there's something on it->stack, call set_iterator_to_next to
11820 proceed with what's on the stack, instead of returning zero.
11821 (set_iterator_to_next): If called at the end of a Lisp string,
11822 proceed to consider_string_end without incrementing string
11823 position. Don't increment display vector index past the end of
11824 the display vector. (Bug#11417)
11825 (pos_visible_p): Don't report a position visible when move_it_to
11826 stopped at the last line of window, which happens to be scanned
11827 backwards by the bidi iteration. (Bug#11464)
11829 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11831 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11832 and right-margin display specs even if the spec is invalid or we
11833 are on a TTY, and thus unable to display on the fringes.
11834 That's because the text with the property will not be displayed anyway,
11835 so we need to signal to the caller that this is a "replacing"
11836 display spec. This fixes display when the spec is invalid or we
11839 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11841 * unexaix.c (make_hdr): Fix typo in prototype.
11842 This bug broke the build on AIX. Problem reported by Gilles Pion.
11844 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11846 * keyboard.c (kbd_buffer_get_event): Read special events also in
11847 batch mode. (Bug#11415)
11849 2012-05-12 Glenn Morris <rgm@gnu.org>

11853 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11855 * lisp.mk (lisp): Add newcomment.elc.
11857 2012-05-12 Glenn Morris <rgm@gnu.org>
11859 * Makefile.in (MKDIR_P): New, set by configure.
11860 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11862 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11864 Remove unused function hourglass_started.
11865 * dispextern.h (hourglass_started):
11866 * w32fns.c (hourglass_started):
11867 * xdisp.c (hourglass_started): Remove.

11871 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11872 Update dependencies.
11874 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11876 * xgselect.c (xg_select): Put maxfds+1 into a var.
11877 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11879 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11881 2012-05-10 Dave Abrahams <dave@boostpro.com>
11883 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11884 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11886 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11888 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11889 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11890 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11891 Initialize xd_registered_buses.
11893 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11895 Untag more efficiently if USE_LSB_TAG.
11896 This is based on a proposal by YAMAMOTO Mitsuharu in
11897 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11898 For an admittedly artificial (nth 8000 longlist) benchmark on
11899 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11900 Emacs's overall text size by 1%.
11901 * lisp.h (XUNTAG): New macro.
11902 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11903 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11904 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11905 * eval.c (Fautoload):
11906 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11907 * frame.h (XFRAME): Use XUNTAG.
11909 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11910 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11911 Remove unportable assumptions about print widths of types like
11913 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11914 intptr_t when converting between pointer and integer, to avoid GCC
11915 warnings about wrong width.
11917 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11919 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11920 stack for each reader_thread, instead of defaulting to 8MB
11921 determined by the linker. This avoids failures in creating
11922 subprocesses on Windows 7, see the discussion in this thread:
11923 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11925 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11927 Fix up display of the *Minibuf-0* buffer in the mini window.
11928 * keyboard.c (read_char): Don't clear the echo area if there's no
11930 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11931 contents of *Minibuf-0*) if there's no message displayed in its stead.
11933 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11935 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11938 2012-05-06 Chong Yidong <cyd@gnu.org>
11940 * lisp.mk (lisp): Update.
11942 2012-05-05 Jim Meyering <meyering@redhat.com>
11944 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11946 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11948 * data.c (PUT_ERROR): New macro.
11949 (syms_of_data): Use it. Add new error type `user-error'.
11950 * undo.c (user_error): New function.
11951 (Fprimitive_undo): Use it.
11952 * print.c (print_error_message): Adjust print style for `user-error'.
11953 * keyboard.c (user_error): New function.
11954 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11956 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11958 Do not limit current-time-string to years 1000..9999.
11959 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11960 (Fcurrent_time_string): Support any year that is supported by the
11961 underlying localtime representation. Don't use asctime, as it
11962 has undefined behavior for years outside the range -999..9999.
11964 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11966 Fix race conditions involving setenv, gmtime, localtime, asctime.
11967 Without this fix, interrupts could mess up code that uses these
11968 nonreentrant functions, since setting TZ invalidates existing
11969 tm_zone or tzname values, and since most of these functions return
11970 pointers to static storage.
11971 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11972 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11973 Grow the critical sections to include not just invoking
11974 localtime/gmtime, but also accessing these functions' results
11975 including their tm_zone values if any, and any related TZ setting.
11976 (format_time_string): Last arg is now struct tm *, not struct tm **,
11977 so that the struct tm is saved in the critical section.
11978 All callers changed. Simplify allocation of initial buffer, partly
11979 motivated by the fact that memory allocation needs to be outside
11980 the critical section.
11982 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11984 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11985 with RESET_INTERVAL.
11987 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11988 Remove duplicated buffer name initialization.
11990 2012-05-02 Jim Meyering <jim@meyering.net>
11992 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11994 * xfns.c (x_window): Use xstrdup (Bug#11375).
11996 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11998 * xdisp.c (pos_visible_p): If already at a newline from the
11999 display string before the 'while' loop, don't walk back the glyphs
12000 from it3.glyph_row. Solves assertion violation when the display
12001 string begins with a newline (egg.el). (Bug#11367)
12003 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12005 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12008 2012-05-01 Glenn Morris <rgm@gnu.org>

12011 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12012 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12013 All were removed before 23.1.
12015 * dispnew.c: Remove HAVE_LIBNCURSES test;
12016 it is always true on relevant platforms.
12018 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12019 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12021 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12023 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12025 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12026 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12029 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12031 Do not avoid creating empty evaporating overlays (Bug#9642).
12032 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12033 That is, do not delete an evaporating overlay if it becomes
12034 empty after its bounds are adjusted to fit within its buffer.
12035 This fix caused other problems, and I'm reverting it until we get
12036 to the bottom of them.
12038 2012-04-27 Chong Yidong <cyd@gnu.org>
12040 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12042 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12044 * xdisp.c (pos_visible_p): If the window start position is beyond
12045 ZV, start the display from buffer beginning. Prevents assertion
12046 violation in init_iterator when the minibuffer window is scrolled
12047 via the scroll bar.
12049 * window.c (window_scroll_pixel_based): Likewise.
12051 2012-04-27 Chong Yidong <cyd@gnu.org>
12053 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12055 2012-04-27 Glenn Morris <rgm@gnu.org>
12057 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12058 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12060 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12062 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12063 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12065 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12067 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12068 display element, check also the underlying string or buffer
12069 character. (Bug#11341)
12071 * w32menu.c: Include w32heap.h.
12072 (add_menu_item): If the call to AppendMenuW (via
12073 unicode_append_menu) fails, disable Unicode menus only if we are
12074 running on Windows 9X/Me.
12076 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12078 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12079 (xgetint): Add missing shift for LSB tags.
12081 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12083 * keyboard.c (read_char): Don't wipe echo area for select window
12084 events: These might get delayed via `mouse-autoselect-window'
12087 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12089 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12090 manipulation of :loaded-from data.
12092 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12094 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12095 now a cons (bug#11311).
12097 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12099 Do not create empty overlays with the evaporate property (Bug#9642).
12100 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12101 if it becomes empty after its bounds are adjusted to fit within
12102 its buffer. Without this fix, in a nonempty buffer (let ((o
12103 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12104 yields an empty overlay that has the evaporate property, which is
12105 not supposed to happen.
12107 Fix minor GTK3 problems found by static checking.
12108 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

12127 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12128 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12129 (__malloc_size_t, __malloc_ptrdiff_t):
12130 Remove. All uses removed, replaced by the definiens if needed,
12131 since we can assume C89 or better now.
12132 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12140 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12141 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):

12317 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
12318 (r_alloc_sbrk): Now static.
12320 Improve ralloc.c interface checking.
12321 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

12351 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12352 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12353 no longer the default.
12354 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12356 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

12379 2012-04-11 Daniel Colascione <dancol@dancol.org>
12381 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12382 against is gone. It's better to use vfork now so that when Cygwin
12383 gains a new, working vfork, we use it automatically (bug#10398).
12385 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
12387 * window.c (save_window_save): Obey window-point-insertion-type.

12399 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
12400 (force_quit_count): New var.
12401 (handle_interrupt): Use it.
12403 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
12405 * w32.c (w32_delayed_load): Record the full path of the library
12406 being loaded (bug#10424).
12408 2012-04-09 Glenn Morris <rgm@gnu.org>
12410 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12411 not just in the obarray, before snarfing them. (Bug#11036)
12413 * Makefile.in ($(leimdir)/leim-list.el):
12414 Pass EMACS rather than BUILT_EMACS.
12416 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12418 * process.c (make_process):
12419 * process.h: Add integer `gnutls_handshakes_tried' member to
12422 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
12423 Add convenience `GNUTLS_LOG2i' macro.
12425 * gnutls.c (gnutls_log_function2i): Convenience log function.
12426 (emacs_gnutls_read): Use new log functions,
12427 `gnutls_handshakes_tried' process member, and
12428 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12429 attempts per process (connection).
12431 2012-04-09 Chong Yidong <cyd@gnu.org>
12433 * eval.c (Fuser_variable_p, user_variable_p_eh)
12434 (lisp_indirect_variable): Functions deleted.
12435 (Fdefvar): Caller changed.
12437 * callint.c (Finteractive, Fcall_interactively):
12438 * minibuf.c (Fread_variable): Callers changed.
12440 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12442 * xdisp.c (set_cursor_from_row): If the display string appears in
12443 the buffer at position that is closer to point than the position
12444 after the display string, display the cursor on the first glyph of
12445 the display string. Fixes cursor display when a 'display' text
12446 property immediately follows invisible text. (Bug#11094)
12448 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12450 composite.c: use 'double' consistently
12451 * composite.c (get_composition_id): Use 'double' consistently
12452 instead of converting 'float' to 'double' and vice versa; this is
12453 easier to understand and avoids a GCC warning.
12455 2012-04-09 Glenn Morris <rgm@gnu.org>
12457 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12458 preparation for dumping it with emacs. (Bug#4789)
12459 (leimdir): New variable.
12460 ($(leimdir)/leim-list.el): New rule.
12461 (emacs$(EXEEXT)): Depend on leim-list.el.
12463 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
12464 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
12465 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
12467 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>

12475 Remove unused local variable.
12477 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12479 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12480 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12481 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12482 objects, as mark_maybe_pointer will catch them otherwise.
12483 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12484 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
12486 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12488 Fix typo that broke non-Windows builds.
12489 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
12491 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12493 Support building on MS-Windows with libxml2.
12495 * makefile.w32-in (OBJ2): Add xml.$(O).
12496 (GLOBAL_SOURCES): Add xml.c.
12497 ($(BLD)/xml.$(O)): New dependency list.
12499 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12500 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12501 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12502 [!WINDOWSNT]: New macros.
12503 (init_libxml2_functions, libxml2_loaded_p): New functions.
12504 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12505 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12506 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12507 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12509 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12510 Call init_libxml2_functions before calling libxml2 functions.
12511 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12513 * emacs.c: Don't include libxml/parser.h.
12514 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12515 xmlCleanupParser directly.
12517 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12519 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12521 * indent.c (Fvertical_motion): If there is a display string at
12522 point, use it.vpos to compute how many lines to backtrack after
12523 move_it_to point. (Bug#11133)
12525 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12527 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12528 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12529 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12530 macros related to unification of CJK characters. For the details,
12531 see the discussion following the message here:
12532 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12534 2012-04-04 Chong Yidong <cyd@gnu.org>
12536 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12538 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12540 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12541 instead of alloca. (Bug#11138)
12543 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12545 * w32menu.c (is_simple_dialog): Properly check lisp types.
12548 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12550 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12551 position we get to after a call to move_it_to fails the
12552 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12553 only if we wind up in a string from display property. (Bug#11063)
12555 * window.c (Fdelete_other_windows_internal): Invalidate the row
12556 and column information about mouse highlight, so that redisplay
12557 restores it after reallocating the glyph matrices. (Bug#7464)
12559 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12560 string comes from a `display' text property, use the buffer
12561 position of that property as if we actually saw that position in
12563 (move_it_by_lines): Remove the assertion that
12564 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12565 violated when there's a before-string at the beginning of a line.
12568 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12570 * xdisp.c (append_space_for_newline): If the default face was
12571 remapped, use the remapped face for the appended newline.
12572 (extend_face_to_end_of_line): Use the remapped default face for
12573 extending the face to the end of the line.
12574 (display_line): Call extend_face_to_end_of_line when the default
12575 face was remapped. (Bug#11068)
12577 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12579 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12581 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12583 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12585 2012-03-27 Glenn Morris <rgm@gnu.org>
12587 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12590 2012-03-26 Kenichi Handa <handa@m17n.org>
12592 * dispextern.h (struct glyph): Fix previous change. Change the
12593 bit length of glyphless.ch to 25 (Bug#11082).
12595 2012-03-26 Chong Yidong <cyd@gnu.org>
12597 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12598 (command_loop_1): Use it; inhibit selection update for
12599 handle-select-window too (Bug#8996).
12601 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12603 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12605 2012-03-25 Kenichi Handa <handa@m17n.org>
12607 * dispextern.h (struct glyph): Change the bit length of
12608 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12610 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12612 * s/ms-w32.h (tzname): Include time.h before redirecting to
12613 _tzname. Fixes the MSVC build. (Bug#9960)
12615 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12617 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12620 * xterm.c (XTread_socket): Only modify handling_signal if
12621 !SYNC_INPUT. (Bug#11080)
12623 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12625 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12626 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12627 when fetching a multibyte character consumes more bytes than
12628 CHAR_BYTES returns, due to unification of CJK characters in
12629 string_char. (Bug#11073)
12631 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12633 * process.c (wait_reading_process_output): Handle pty disconnect
12634 by refraining from sending oneself a SIGCHLD (bug#10933).
12636 2012-03-22 Chong Yidong <cyd@gnu.org>
12638 * dispextern.h (struct it): New member string_from_prefix_prop_p.
12640 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12641 Mark string as coming from a prefix property.
12642 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12643 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12645 2012-03-21 Chong Yidong <cyd@gnu.org>
12647 * xfaces.c (Vface_remapping_alist): Doc fix.
12649 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12651 * w32proc.c (Fw32_set_console_codepage)
12652 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12655 2012-03-20 Chong Yidong <cyd@gnu.org>
12657 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12658 to reflect default non-nil value of redisplay-dont-pause.
12660 2012-03-19 Kenichi Handa <handa@m17n.org>
12662 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12663 it fit in a valid range (Bug#11003).
12665 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12667 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12668 that is not from display property, accept the row as a "cursor
12669 row" if one of the string's character has a non-nil `cursor'
12670 property. Fixes cursor positioning when there are newlines in
12671 overlay strings, e.g. in icomplete.el. (Bug#11035)
12673 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12675 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12677 2012-03-12 Chong Yidong <cyd@gnu.org>
12679 * eval.c (inhibit_lisp_code): Rename from
12680 inhibit_window_configuration_change_hook; move from window.c.
12682 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12683 * window.c (run_window_configuration_change_hook)
12684 (syms_of_window): Callers changed.
12686 2012-03-11 Chong Yidong <cyd@gnu.org>
12688 * keymap.c (Fkey_description): Doc fix (Bug#9700).
12690 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12692 2012-03-10 Chong Yidong <cyd@gnu.org>
12694 * frame.c (other_visible_frames): Don't assume the selected frame
12695 is visible (Bug#10955).
12697 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12699 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
12701 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
12703 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12704 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12707 2012-03-03 Glenn Morris <rgm@gnu.org>
12709 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12711 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12713 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12714 position past the first glyph_row that ends at ZV. (Bug#10902)
12715 (redisplay_window, next_element_from_string): Fix typos in
12717 (redisplay_window): Pass to move_it_vertically the margin in
12718 pixels, not in screen lines.
12720 2012-03-02 Glenn Morris <rgm@gnu.org>
12722 * buffer.c (buffer-list-update-hook): Doc fix.
12724 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12726 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12727 push_it before setting up the iterator for the first overlay
12728 string, even if we have an empty string loaded.
12729 (next_overlay_string): If there's an empty string on the iterator
12730 stack, pop the stack. (Bug#10903)
12732 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12734 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12735 Suggested by Stefan Monnier in
12736 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12737 * alloc.c (widen_to_Lisp_Object): New static function.
12738 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12739 and widening them to Lisp_Objects. This would work even if
12740 USE_LSB_TAG is defined and wide integers are used, which might
12741 happen in a future version of Emacs.
12743 2012-02-25 Chong Yidong <cyd@gnu.org>
12745 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12748 * xselect.c (Fx_selection_exists_p): Doc fix.
12749 (x_clipboard_manager_save_all): Print an informative message
12750 before saving to clipboard manager.
12752 2012-02-24 Chong Yidong <cyd@gnu.org>
12754 * keyboard.c (process_special_events): Handle all X selection
12755 requests in kbd_buffer, not just the next one (Bug#8869).
12757 2012-02-23 Chong Yidong <cyd@gnu.org>
12759 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12760 call when setting menu-bar-lines and tool-bar-lines parameters.
12761 (unwind_create_frame_1): New helper function.
12763 * window.c (inhibit_window_configuration_change_hook): New var.
12764 (run_window_configuration_change_hook): Obey it.
12765 (syms_of_window): Initialize it.
12767 2012-02-22 Chong Yidong <cyd@gnu.org>
12769 * xterm.c (x_draw_image_relief): Add missing type check for
12770 Vtool_bar_button_margin (Bug#10743).
12772 2012-02-21 Chong Yidong <cyd@gnu.org>
12774 * fileio.c (Vfile_name_handler_alist): Doc fix.
12776 * buffer.c (Fget_file_buffer): Protect against invalid file
12777 handler return value.
12779 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
12781 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
12782 when computing $valmask.
12784 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12785 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12786 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12787 It's useless in that case, and it can cause problems on hosts
12788 that allocate halves of EMACS_INT values separately.
12789 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12790 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12791 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12792 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12793 it avoids undefined behavior on hosts where shifting right by more
12794 than the word width has undefined behavior.
12796 2012-02-19 Chong Yidong <cyd@gnu.org>
12798 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12799 (Funhandled_file_name_directory, Ffile_name_as_directory)
12800 (Fdirectory_file_name, Fexpand_file_name)
12801 (Fsubstitute_in_file_name): Protect against invalid file handler
12802 return values (Bug#10845).
12804 2012-02-18 Eli Zaretskii <eliz@gnu.org>
12806 * .gdbinit (pitx): Fix incorrect references to fields of the
12809 2012-02-17 Chong Yidong <cyd@gnu.org>
12811 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
12813 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
12815 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
12816 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12818 2012-02-15 Chong Yidong <cyd@gnu.org>
12820 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12821 marked as special. Also, starting docstrings with * is obsolete.
12823 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
12825 * gnutls.c (emacs_gnutls_write): Fix last change.
12827 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
12829 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
12832 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
12834 * keymap.c (Fsingle_key_description): Handle char ranges.
12836 2012-02-12 Chong Yidong <cyd@gnu.org>
12838 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12839 as that creates a dangerous corner case.
12841 * window.c (Fdelete_window_internal): Invalidate the mouse
12842 highlight (Bug#9904).
12844 2012-02-12 Glenn Morris <rgm@gnu.org>
12846 * xselect.c (Fx_own_selection_internal)
12847 (Fx_get_selection_internal, Fx_disown_selection_internal)
12848 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12849 * nsselect.m (Fx_own_selection_internal)
12850 (Fx_disown_selection_internal, Fx_selection_exists_p)
12851 (Fx_selection_owner_p, Fx_get_selection_internal):
12852 Sync docs and argument specs with the xselect.c versions.
12854 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

13401 cases where the *-change-functions have already been properly called
13404 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
13406 * keyboard.c (interrupt_signal): Don't call kill-emacs when

13411 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13412 verifies glyph row's hash code--we have just reallocated the
13413 glyphs, so their contents can be complete garbage. (Bug#10164)

13492 (start_display): Don't move to the next line if the display should
13493 start at a newline that is part of a display vector or an overlay

13573 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13574 Otherwise, valgrind does not work on some platforms.
13575 Problem reported by Andreas Schwab in
13576 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13577 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13578 is set, removing the need for VIRT_ADDRESS_VARIES.
13579 (PURE_P): Use a more-efficient implementation that needs just one
13580 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13581 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13582 to 4 (xorl, subq, cmpq, setbe).
13583 * alloc.c (pure): Always extern now, since that's the

13586 consistency with the new puresize.h.
13587 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13588 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13594 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13595 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13596 behave as if the cursor position were at the window margin.
13598 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13599 and the cursor position is out of bounds, behave as if the cursor
13600 position were at the window margin. (Bug#10075)
13602 2011-11-18 Chong Yidong <cyd@gnu.org>
13604 * window.c (Fwindow_combination_limit): Make first argument

13623 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13625 * xdisp.c (row_hash): New function, body extracted from
13626 compute_line_metrics.
13627 (compute_line_metrics): Call row_hash, instead of computing the
13630 * dispnew.c (verify_row_hash): Call row_hash for computing the
13631 hash code of a row, instead of duplicating code from xdisp.c.
13633 * dispextern.h (row_hash): Add prototype.
13635 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13637 * frame.c (delete_frame): Don't delete the terminal when the last

13671 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13673 * xdisp.c (display_line): Move the call to
13674 highlight_trailing_whitespace before the call to
13675 compute_line_metrics, since the latter needs to see the final
13676 faces of all the glyphs to compute ROW's hash value.
13677 Fixes assertion violations in row_equal_p. (Bug#10035)
13679 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

13686 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13687 with user-defined heap size. Bump the default size of the temacs

13691 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13692 current_matrix and desired_matrix. (Bug#9990)
13693 (verify_row_hash) [XASSERTS]: New function.

13740 Avoid some portability problems by eschewing 'extern inline' functions.
13741 The trivial performance wins aren't worth the portability hassles; see
13742 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13744 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

13810 * xmenu.c (cleanup_widget_value_tree): New function.
13811 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
13812 calling free_menubar_widget_value_tree directly (Bug#9830).
13814 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
13816 Fix some portability problems with 'inline'.
13817 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13818 (window_box_width, window_box_left, window_box_left_offset)
13819 (window_box_right, window_box_right_offset): Declare extern.
13820 Otherwise, these inline functions do not conform to C99 and
13821 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13822 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13823 * intervals.c (adjust_intervals_for_insertion)
13824 (adjust_intervals_for_deletion): Now extern, because otherwise the
13825 extern inline functions 'offset_intervals' couldn't refer to it.
13826 (static_offset_intervals): Remove.
13827 (offset_intervals): Rewrite using the old contents of
13828 static_offset_intervals. The old version didn't conform to C99
13829 because an extern inline function contained a reference to an
13830 identifier with static linkage.
13832 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
13834 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

13852 (Fwindow_vscroll): Doc fix.
13853 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
13854 argument, since it makes no sense to pass a live window and for
13855 consistency with window-child.

13883 (unwind_create_frame): New function (Bug#9943).
13884 (Fx_create_frame): Restructure code to be more similar to the one in
13885 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

13896 official. Move initialization of image_cache_refcount and
13897 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

13937 previous/next-single-property-change returns nil, treat that as
13938 the beginning or the end of the buffer. (Bug#9955)
13940 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
13942 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

13977 past the beginning of the current glyph matrix.
13979 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
13981 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

14065 (w32font_open_internal, compute_metrics):
14066 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14067 instead of calling the "wide" APIs directly.
14069 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14071 * w32.h (syms_of_w32font): Add prototype.

14077 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14078 (Fmove_to_window_line): Doc fix.
14080 2011-10-27 Chong Yidong <cyd@gnu.org>
14082 * process.c (make_process): Set gnutls_state to NULL.
14084 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14085 non-NULL, regardless of GNUTLS_INITSTAGE.

14134 (bidi_resolve_weak): Don't enter the expensive loop if the current
14135 position is before next_en_pos. Record the bidi type of the first
14136 non-ET, non-BN character we find, in addition to its position.
14137 (bidi_level_of_next_char): Invalidate next_en_type when
14138 next_en_pos is over-stepped.
14140 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14142 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14143 * editfns.c: Rewrite current-time-zone so that it invokes
14144 the equivalent of (format-time-string "%Z") to get the time zone name.
14145 This fixes a bug when the time zone name contains characters that
14146 need converting from the system time locale to Emacs internal format.
14147 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14148 that patch fixed format-time-string to do the conversion, but
14149 I forgot to fix current-time-zone.
14150 (format_time_string): New function, containing most of
14151 what Fformat_time_string used to contain.
14152 (Fformat_time_string): Rewrite in terms of format_time_string.
14153 This doesn't change this function's behavior.
14154 (current-time-zone): Rewrite to use format_time_string.
14155 This fixes the bug reported by Michael Schierl in
14156 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14157 Jason Rumney's 2007-06-07 change worked around this bug, but
14159 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14161 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14163 * xdisp.c (start_display): If the character at POS is displayed
14164 via a display vector, reset IT->current.dpvec_index to zero.
14165 (try_window_reusing_current_matrix): If a line ends in a display
14166 vector or the next line starts in a display vector, continue
14167 redrawing the window even though the character position of
14168 start_row was reached.
14171 2011-10-18 Chong Yidong <cyd@gnu.org>
14173 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14174 with nobreak-char-display too.
14176 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14178 Fix part 3 of bug#9771.
14179 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14180 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14181 non-neutral characters if the current character is a paragraph
14182 separator (a.k.a. Newline). This avoids running the same
14183 expensive loop twice, once when we consume the preceding newline
14184 and the other time when the line actually needs to be displayed.
14185 Avoid the loop when we see neutrals on the base embedding level
14186 following a character whose directionality is the same as the
14187 paragraph's. This avoids running the expensive loop when a line
14188 ends in a long sequence of neutrals, like control characters.
14189 Add assertion against STRONG_AL type. Slightly rearrange code
14190 that determines the type of a neutral given the first non-neutral
14192 (bidi_level_of_next_char): Set next_en_pos to zero when
14193 invalidating its info.
14195 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14197 * xdisp.c (push_display_prop): Determine whether to record string
14198 or buffer position by IT->string, not by IT->method. Allow
14199 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14200 (move_it_vertically_backward): Don't look for character position
14201 immediately after the newline when in a continuation line.
14204 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14206 * window.c (coordinates_in_window): Rewrite and delabelize
14207 vertical border check. (Bug#5357) (Bug#9618)

14211 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14212 errors in XSetWindowBorder (bug#9310).
14214 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14216 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14217 avoid crash when xmalloc overrun checking is enabled.
14219 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14221 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14222 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14223 cursor motion with <left> and <right> arrow keys.
14225 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14226 some callers set that themselves.
14228 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14230 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14231 display string and the previous row comes from the same string and
14232 is empty. (Bug#9739) (Bug#9738)
14234 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14236 * doc.c (get_doc_string): Encode file name (bug#9735).
14238 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14240 * bidi.c (bidi_level_of_next_char):
14241 * xdisp.c (get_visually_first_element): Remove old incorrect
14242 comments regarding the Unicode Line Separator character.
14244 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14246 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

14252 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14254 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14255 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14257 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14258 Some packages use them to denote characters with modifiers.
14260 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14262 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14263 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14264 matching a pp-number. Rename parameter var to var1.
14266 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14268 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14270 2011-10-08 Glenn Morris <rgm@gnu.org>
14272 * callint.c (Fcall_interactively): Give a more explicit error for the
14273 'c' case with a non-character input. (Bug#8479)
14275 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14277 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14279 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14280 lines that are hscrolled on the left.
14282 * dispnew.c (buffer_posn_from_coords): Account for a possible
14283 presence of header-line. (Bug#4426)
14285 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14287 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14288 Don't advertise functionality which we discourage or doesn't work.
14290 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14292 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14293 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14294 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14295 this makes Emacs dump core during garbage collection on rare
14296 occasions. sizeof is obviously inferior to offsetof here, so
14297 stick with offsetof.
14298 (GC_POINTER_ALIGNMENT): New macro.
14299 (mark_memory): Omit 3rd (offset) arg; caller changed.
14300 Don't assume EMACS_INT alignment is the same as pointer alignment.
14302 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14304 * keyboard.c (read_key_sequence_remapped): New var.
14305 (read_key_sequence): Compute remapping in the right buffer.
14306 (command_loop_1): Use read_key_sequence's remapping directly.
14308 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14310 * dired.c (file_name_completion): Don't expand file name.
14311 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14312 before checking file name handler.
14314 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14315 they've been requested explicitly (bug#9591).
14317 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14319 * keymap.c (Fsingle_key_description): Use make_specified_string
14320 instead of build_string to build string from push_key_description.
14323 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14325 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14326 This fixes a Y2038 bug on 64-bit hosts.
14327 * buffer.c (reset_buffer):
14328 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14329 (Fclear_buffer_auto_save_failure):
14330 Use 0, not -1, to represent an unset failure time, since time_t
14331 might not be signed.
14333 Remove dependency on glibc malloc internals.
14334 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14335 Move back here from lisp.h, but with their new implementations.
14336 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14337 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14338 * charset.c (charset_table_init): New static var.
14339 (syms_of_charset): Use it instead of xmalloc. This removes a
14340 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14341 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14342 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14343 Move back to alloc.c.
14344 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14345 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14347 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14349 * nsterm.m (windowDidResize): Call x_set_window_size only when
14350 ns_in_resize is true. Otherwise set pixelwidth/height and
14351 call change_frame_size (Bug#9628).
14353 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14355 Port --enable-checking=all to Fedora 14 x86-64.
14356 * charset.c (syms_of_charset): Also account for glibc malloc's
14357 internal overhead when calculating the initial malloc maximum.
14359 Port --enable-checking=all to Fedora 14 x86.
14360 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14362 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14363 (overrun_check_realloc, overrun_check_free):
14364 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14365 That way, xmalloc returns a properly-aligned pointer even if
14366 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14367 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14368 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14369 into account when calculating the initial malloc maximum.
14370 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14371 Move here from alloc.c, so that charset.c can use it too.
14372 Properly align; the old code wasn't right for common 32-bit hosts
14373 when configured with --enable-checking=all.
14374 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14375 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14377 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14379 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14382 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14384 * xdisp.c (compute_display_string_end): If there's no display
14385 string at CHARPOS, return -1.
14387 * bidi.c (bidi_fetch_char): When compute_display_string_end
14388 returns a negative value, treat the character as a normal
14389 character not covered by a display string. (Bug#9624)
14391 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14393 * lread.c (Fread_from_string): Fix typo in docstring.
14395 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14397 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14398 newline, reseat the iterator instead of bidi-iterating there one
14399 character at a time. (Bug#9610)
14400 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14401 TO_CHARPOS if the bidi iterator is at base embedding level.
14403 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14405 * lread.c (readevalloop): Use correct code for NBSP.
14406 (read1): Likewise. (Bug#9608)
14408 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14410 * dbusbind.c (Fdbus_register_signal): When service is not
14411 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14413 2011-09-25 Glenn Morris <rgm@gnu.org>
14415 * buffer.c (truncate-lines): Doc fix.
14417 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14419 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14420 (Fset_window_next_buffers): Doc fix.
14422 2011-09-24 Glenn Morris <rgm@gnu.org>
14424 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14426 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14428 Fix minor problems found by static checking.
14429 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14430 * indent.c (Fvertical_motion): Fix == vs = typo.
14432 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14434 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14435 Default value is now t. Doc fix.
14437 * indent.c (Fvertical_motion): Compute and apply the overshoot
14438 logic when moving up, not only when moving down. Fix the
14439 confusing name and values of the it_overshoot_expected variable;
14440 logic changes accordingly. (Bug#9254) (Bug#9549)
14442 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14443 CHARPOS is covered by a display string which includes newlines.
14444 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14445 is covered by a display string with embedded newlines.
14447 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14449 * dbusbind.c (Fdbus_register_signal): Add match rule to
14450 Vdbus_registered_objects_table. (Bug#9581)
14451 (Fdbus_register_method, Vdbus_registered_objects_table):
14454 2011-09-24 Jim Meyering <meyering@redhat.com>
14456 do not ignore write error for any output size
14457 The previous change was incomplete.
14458 While it makes emacs --batch detect the vast majority of stdout
14459 write failures, errors were still ignored whenever the output size is
14460 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14461 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14462 && echo FAIL: ignored write error
14463 FAIL: ignored write error
14464 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14465 && echo FAIL: ignored write error
14466 FAIL: ignored write error
14467 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14469 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14471 * emacs.c (Fkill_emacs): In noninteractive mode exit
14472 non-successfully if a write error occurred on stdout. (Bug#9574)
14474 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14476 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14479 * dispextern.h (struct it): Update the comment documenting what
14482 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14484 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14485 a display string, extend search for cursor position to end of row.
14486 (find_row_edges): If the row ends in a newline from a display
14487 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14488 Handle the case of a display string with multiple newlines.
14489 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14490 non-empty line. Fixes confusing cursor motion with arrow keys at
14491 the beginning of a line that starts with whitespace.
14493 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14495 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14498 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14500 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14501 boolean (Bug#9154).
14503 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14505 * xdisp.c (display_line): Record maximum and minimum buffer
14506 positions even if no glyphs were produced (e.g., by a zero-width
14507 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14508 buffer positions that will be removed from the glyph row because
14510 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14511 column is beyond frame width: don't subtract 1 "pixel" when
14512 computing width of the stretch.
14513 (reseat_at_next_visible_line_start): Undo the change made on
14514 2011-09-17 that saved paragraph information and restored it after
14515 the call to `reseat'. (Bug#9545)
14517 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14519 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14520 and turn window cursor on if cleared (Bug#9415).
14522 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14524 * search.c (boyer_moore): Take unibyte characters from pattern
14525 literally. (Bug#9458)
14527 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14529 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14531 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14533 Fix minor problem found by static checking.
14534 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14535 initialized, to pacify gcc -Wuninitialized.
14537 * fileio.c: Report proper errno when syscall falls.
14538 (Finsert_file_contents): Save and restore errno,
14539 so that report_file_error outputs the correct diagnostic.
14540 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14542 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14544 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14546 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14548 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14549 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14551 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14553 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14554 about the current paragraph and restore it after the call to reseat.
14556 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14557 (bidi_find_paragraph_start): Search back for paragraph beginning
14558 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14559 (bidi_move_to_visually_next): Only trigger paragraph-related
14560 computations when the last character is a newline or at EOB, not
14561 just any NEUTRAL_B. (Bug#9470)
14563 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14564 truncated lines if point is covered by a display string. (Bug#9524)
14566 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14568 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14569 (cons_to_x_long): New function.
14570 (lisp_data_to_selection_data): Use it. Correct the test for
14571 short-versus-long data; it was negated. Break out of vector
14572 loop, for efficiency, when a long datum is discovered.
14574 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14576 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14578 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14580 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14581 GCC PR/17406) by declaring this function with external scope.
14583 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14585 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14586 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14588 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14590 * editfns.c (Fformat): Correctly handle text properties on "%%".
14592 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14594 * xterm.c (x_draw_composite_glyph_string_foreground):
14595 * w32term.c (x_draw_composite_glyph_string_foreground):
14596 * term.c (encode_terminal_code):
14597 * composite.c (composition_update_it, get_composition_id):
14598 * xdisp.c (get_next_display_element)
14599 (fill_composite_glyph_string): Add comments about special meaning
14600 of TAB characters in a composition.
14602 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14604 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14605 This occurs when processing a multibyte format.
14606 Problem reported by Wolfgang Jenker.
14608 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14610 * xdisp.c (try_cursor_movement): Only check for exact match if
14611 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14613 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14615 Remove unused external symbols.
14616 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14617 * xdisp.c (calc_pixel_width_or_height): Now static.
14618 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14619 * indent.c (check_display_width):
14620 * w32term.c: Fix comment to match code.
14621 * xterm.c, xterm.h (x_catching_errors): Remove.
14623 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14625 * xselect.c: Use signed conversions more consistently (Bug#9498).
14626 (selection_data_to_lisp_data): Assume incoming selection data are
14627 signed integers, not unsigned. This is to be consistent with
14628 outgoing selection data, which was modified to use signed integers
14629 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14630 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14631 expects long, not unsigned long.
14633 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14635 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14636 computation of loop end. Reported by Johan Bockgård
14639 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14641 * frame.c (Fother_visible_frames_p): Function deleted.
14643 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14645 * indent.c (compute_motion): Process display vector front to back
14646 rather than the other way around. (Bug#2496)
14648 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14650 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14652 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14654 * minibuf.c (Fread_from_minibuffer): Doc fix.
14656 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14658 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14659 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14661 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14663 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14664 value for non-existent files.
14666 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14668 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14669 set its "size" to -1. This will set the modtime_size field of
14670 the corresponding buffer to -1, which is what
14671 verify-visited-file-modtime expects for files that do not exist.
14674 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14676 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14678 * lisp.h: ... from here. push_key_description is no longer
14679 defined in keyboard.c, so its declaration should not be in
14680 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14681 logically belongs with push_key_description.
14683 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14685 * buffer.h: Include <sys/types.h> instead of <time.h>.
14686 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14687 Problem reported by Herbert J. Skuhra.
14689 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14691 * xml.c (parse_region): Make the parsing work for
14692 non-comment-starting XML files again (bug#9144).
14694 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14696 * image.c (gif_load): Fix calculation of bottom and right corner.
14699 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14701 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14702 redisplay in small windows.
14704 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14706 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14708 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14710 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14711 Operate on live windows only.
14713 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14715 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14717 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14719 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14720 only under bidi iteration.
14722 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14724 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14726 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14728 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14729 Without this fix, the command to link temacs failed due to an
14730 undefined symbol __builtin_isnan. This is because
14731 /usr/include/iso/math_c99.h #defines isnan(x) to
14732 __builtin_isnan(x), but the bundled gcc, which identifies itself
14733 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14735 * floatfns.c (isnan): #undef, and then #define to a clone of
14737 (Fisnan): Always define, since it's always available now.
14738 (syms_of_floatfns): Always define isnan at the Lisp level.
14740 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14742 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14744 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14746 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14747 The previous code assumed that file offsets (off_t values) fit in
14748 EMACS_INT variables, which is not true on typical 32-bit hosts.
14749 The code messed up by falsely reporting buffer overflow in cases
14750 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14751 when "big" contains more than 2**29 bytes, even though this
14752 inserts just one byte and does not overflow the buffer.
14753 (Finsert_file_contents): Store file offsets as off_t
14754 values, not as EMACS_INT values. Check for overflow when
14755 converting between EMACS_INT and off_t. When checking for
14756 buffer overflow or for overlap, take the offsets into account.
14757 Don't use EMACS_INT for small values where int suffices.
14758 When checking for overlap, fix a typo: ZV was used where
14759 ZV_BYTE was intended.
14760 (Fwrite_region): Don't assume off_t fits into 'long'.
14761 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14763 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14765 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14767 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14769 sprintf-related integer and memory overflow issues (Bug#9412).
14771 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14772 (esprintf, exprintf, evxprintf): New functions.
14773 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14774 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14775 (modify_event_symbol): Do not assume that the length of
14776 name_alist_or_stem is safe to alloca and fits in int.
14777 (Fexecute_extended_command): Likewise for function name and binding.
14778 (Frecursion_depth): Wrap around reliably on integer overflow.
14779 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14780 since some callers pass EMACS_INT values.
14781 (Fsingle_key_description): Don't crash if symbol name contains more
14782 than MAX_ALLOCA bytes.
14783 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14784 (get_minibuffer): Arg is now EMACS_INT, not int.
14785 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14786 (esprintf, exprintf, evxprintf): New decls.
14787 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14789 * dbusbind.c (signature_cat): New function.
14790 (xd_signature, Fdbus_register_signal):
14791 Do not overrun buffer; instead, report string overflow.
14793 * dispnew.c (add_window_display_history): Don't overrun buffer.
14794 Truncate instead; this is OK since it's just a log.
14796 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14797 even if the time zone offset is outlandishly large.
14798 Don't mishandle offset == INT_MIN.
14800 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14801 when creating daemon; the previous buffer-overflow check was incorrect.
14803 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14804 which has the guts of the old verror function.
14806 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14807 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14809 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14810 (font_unparse_xlfd): Don't blindly alloca long strings.
14811 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14812 fits in int, when using sprintf. Use single snprintf to count
14813 length of string rather than counting it via multiple sprintfs;
14814 that's simpler and more reliable.
14815 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14816 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14817 sprintf, in case result does not fit in int.
14819 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14820 (fontset_from_font): Print it.
14822 * frame.c (tty_frame_count): Now printmax_t, not int.
14823 (make_terminal_frame, set_term_frame_name): Print it.
14824 (x_report_frame_params): In X, window IDs are unsigned long,
14825 not signed long, so print them as unsigned.
14826 (validate_x_resource_name): Check for implausibly long names,
14827 and don't assume name length fits in 'int'.
14828 (x_get_resource_string): Don't blindly alloca invocation name;
14829 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14832 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14833 (xg_check_special_colors, xg_set_geometry):
14834 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14836 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14837 Use esprintf, not sprintf, in case result does not fit in int.
14839 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14840 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14841 it as a large positive number.
14842 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14843 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14845 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14846 in case result does not fit in int.
14848 * print.c (float_to_string): Detect width overflow more reliably.
14849 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14850 buffer overrun. Don't assume list length fits in 'int'. Treat
14851 print length of 0 as 0, not as infinity; to be consistent with other
14852 uses of print length in this function. Don't overflow print length
14853 index. Don't assume hash table size fits in 'long', or that
14854 vectorlike size fits in 'unsigned long'.
14856 * process.c (make_process): Use printmax_t, not int, to format
14857 process-name gensyms.
14859 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14861 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14862 to avoid potential buffer overrun.
14864 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14865 if X resource line is longer than 512 bytes.
14867 * xfns.c (x_window): Make sprintf buffer a bit bigger
14868 to avoid potential buffer overrun.
14870 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14872 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14874 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14876 Integer overflow fixes for scrolling, etc.
14877 Without these, Emacs silently mishandles large integers sometimes.
14878 For example, "C-u 4294967297 M-x recenter" was treated as if
14879 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14881 * xdisp.c (try_window_id): Check Emacs fixnum range before
14882 converting to 'int'.
14884 * window.c (window_scroll_line_based, Frecenter):
14885 Check that an Emacs fixnum is in range before assigning it to 'int'.
14886 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14887 values converted from Emacs fixnums.
14888 (Frecenter): Don't wrap around a line count if it is out of 'int'
14889 range; instead, treat it as an extreme value.
14890 (Fset_window_configuration, compare_window_configurations):
14891 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14893 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14894 that can exceed INT_MAX. Check that EMACS_INT value is in range
14895 before assigning it to the (possibly-narrower) index.
14896 (match_limit): Don't assume that a fixnum can fit in 'int'.
14898 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14901 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14902 (Fvertical_motion): Don't wrap around LINES values that don't fit
14903 in 'int'. Instead, treat them as extreme values. This is good
14904 enough for windows, which can't have more than INT_MAX lines anyway.
14906 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14908 * Require libxml/parser.h to avoid compilation warning.
14910 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14912 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14913 since this reportedly can destroy thread storage.
14915 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14917 * syntax.c (find_defun_start): Update all cache variables if
14918 exiting early (Bug#9401).
14920 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14922 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14924 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14925 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14926 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14928 * term.c (tty_append_glyph): New function.
14929 (produce_stretch_glyph): Static function and its prototype deleted.
14931 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14934 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14936 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14937 when checking :margin (Bug#9390).
14938 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14939 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14940 so that the name doesn't mislead. All uses changed.
14942 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14944 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14947 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14949 * xdisp.c (move_it_to): Don't bail out early when reaching
14950 position beyond to_charpos, if we are scanning backwards.
14951 (move_it_vertically_backward): When DY == 0, make sure we get to
14952 the first character in the line after the newline.
14954 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14956 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14957 (ccl_driver): Do not generate an out-of-range pointer.
14958 (Fccl_execute_on_string): Remove unnecessary check for
14959 integer overflow, noted by Stefan Monnier in
14960 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14961 Remove a FIXME that didn't need fixing.
14962 Simplify the newly-introduced buffer reallocation code.
14964 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14966 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14968 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14970 Integer and memory overflow issues (Bug#9196).
14972 * doc.c (get_doc_string): Rework so that
14973 get_doc_string_buffer_size is the actual buffer size, rather than
14974 being 1 less than the actual buffer size; this makes xpalloc more
14977 * image.c (x_allocate_bitmap_record, cache_image):
14978 * xselect.c (Fx_register_dnd_atom):
14979 Simplify previous changes by using xpalloc.
14981 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14982 since either will do and ptrdiff_t is convenient with xpalloc.
14984 * charset.c (charset_table_size)
14985 (struct charset_sort_data.priority): Now ptrdiff_t.
14986 (charset_compare): Don't overflow if priorities differ greatly.
14987 (Fsort_charsets): Don't assume list length fits in int.
14988 Check for size-calculation overflow when allocating sort data.
14989 (syms_of_charset): Allocate an initial charset table that is
14990 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14992 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14994 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14995 The actual value is always <= INT_MAX, and leaving it unsigned made
14996 overflow checking harder.
14998 * dispextern.h (struct glyph_matrix.rows_allocated)
14999 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15000 with xpalloc. The values are still always <= INT_MAX.
15002 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15004 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15005 (SAFE_NALLOCA): New macro.
15007 * region-cache.c (struct boundary.pos, find_cache_boundary)
15008 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15009 (set_cache_region, invalidate_region_cache)
15010 (revalidate_region_cache, know_region_cache, region_cache_forward)
15011 (region_cache_backward, pp_cache):
15012 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15013 so that ptrdiff_t * can be passed to xpalloc.
15014 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15015 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15016 (pp_cache): Don't assume cache_len fits in int.
15017 * region-cache.h: Adjust extern decls to match.
15019 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15020 EMACS_INT, since either will do, for xpalloc.
15022 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15023 (xnmalloc, xnrealloc, xpalloc): New functions.
15025 * bidi.c (bidi_shelve_header_size): New constant.
15026 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15027 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15029 * bidi.c (bidi_cache_shrink):
15030 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15032 Don't update size of array until after memory allocation succeeds,
15033 because xmalloc/xrealloc may not return.
15034 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15035 now that we have proper integer overflow checking.
15036 (record_overlay_string, overlay_strings): Catch overflows when
15037 calculating size of overlay_str_buf.
15039 * callproc.c (Fcall_process): Check for size overflow when
15040 calculating size of args2.
15041 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15042 Normally we prefer signed values, but sticking with ptrdiff_t would
15043 require adding more-complicated checks.
15045 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15046 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15047 Redo buffer-overflow calculations to avoid integer overflow.
15048 Add a FIXME comment where memory seems to be over-allocated.
15050 * character.c (Fstring): Check for size-calculation overflow.
15052 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15053 unnecessary integer overflow. Check for size overflow.
15054 (encode_coding_object): Don't update size until xmalloc succeeds.
15056 * composite.c (get_composition_id): Check for overflow in glyph
15057 length calculations.
15059 Integer and memory overflow fixes for display code.
15060 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15061 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15062 (scrolling_window): Check for overflow in size calculations.
15063 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15064 Don't assume glyph table len fits in int.

15066 (row_table_size): Now ptrdiff_t, not int.
15067 (scrolling_window): Avoid overflow in size calculations.
15068 Don't update size until allocation succeeds.
15069 * fns.c (concat): Check for overflow in size calculations.
15070 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15071 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15072 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15074 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15075 (get_doc_string): Check for size calculation overflow.
15076 Don't update size until allocation succeeds.
15077 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15078 EMACS_INT, where ptrdiff_t will do.
15079 (Fsubstitute_command_keys): Check for string overflow.
15081 * editfns.c (set_time_zone_rule): Don't assume environment length
15083 (message_length): Now ptrdiff_t, not int.
15084 (Fmessage_box): Don't update size until allocation succeeds.
15085 Don't assume message length fits in int.
15086 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15088 * emacs.c (main): Do not reallocate argv, since there is a null at
15089 the end that can be overwritten, and this way there's no need to
15090 worry about size-calculation overflow.
15091 (sort_args): Check for size-calculation overflow.
15093 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15095 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15097 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15098 (x_set_scroll_bar_width, x_figure_window_size):
15099 Check for integer overflow.
15100 (x_set_alpha): Do not assume XINT fits in int.
15102 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15103 This is for the members text_lines, text_cols, total_lines, total_cols,
15104 where the system imposes an 'int' limit.
15106 * fringe.c (Fdefine_fringe_bitmap):
15107 Don't update size until alloc works.
15109 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15110 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15112 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15113 Check for size-calculation overflow.
15114 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15115 do, as we prefer signed integers.
15116 (id_to_widget.max_size, id_to_widget.used)
15117 (xg_store_widget_in_map, xg_remove_widget_from_map)
15118 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15119 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15120 Use and return ptrdiff_t, not int.
15121 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15122 * gtkutil.h: Change prototypes to match the above.
15124 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15125 are duplicate now that they've been promoted to lisp.h.
15126 (x_allocate_bitmap_record, x_alloc_image_color)
15127 (make_image_cache, cache_image, xpm_load):
15128 Don't update size until alloc is done.
15129 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15131 Check for size calculation overflow.
15132 (ct_colors_allocated_max): New constant.
15133 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15136 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15137 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15138 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15139 Use ptrdiff_t, not int, to count maps.
15140 (read_char_minibuf_menu_prompt): Check for overflow in size
15141 calculations. Don't update size until allocation succeeds.
15142 Redo calculations to avoid overflow.
15143 * keyboard.h: Change prototypes to match the above.
15145 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15147 (current_minor_maps): Check for size calculation overflow.
15148 * keymap.h: Change prototypes to match the above.
15150 * lread.c (read1, init_obarray): Don't update size until alloc done.
15152 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15153 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15155 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15156 Now ptrdiff_t, not int.

15169 (Fset_match_data): Don't assume list lengths fit in 'int'.
15171 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15172 for command line length. Do not attempt to address one before the
15173 beginning of an array, as that's not portable.
15175 * term.c (max_frame_lines): Remove; unused.

15202 (Finternal_make_lisp_face, cache_face):
15203 Check for size calculation overflow.
15204 (cache_face): Treat size calculation overflows as if they were
15205 memory exhaustion (the usual treatment), rather than aborting.
15207 * xfns.c (x_encode_text, x_set_name_internal)
15208 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15209 sizes, since they can exceed INT_MAX in size. Check for size
15210 calculation overflow.
15212 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15213 (xg_select): Check for size calculation overflow.
15214 Don't update size until alloc done.
15216 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15217 as sprintf is limited to int lengths.
15219 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15220 (X_LONG_MIN): New macros.
15221 Use them to make the following changes clearer.
15222 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15223 This change doesn't affect the value now, but it may help remind
15224 future maintainers not to raise the value too much later.
15225 (SELECTION_QUANTUM): Remove, replacing with ...
15226 (selection_quantum): ... new function, which avoids overflow.
15228 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15229 assumption that selection length fits in 'int'.
15230 (x_reply_selection_request, x_handle_selection_request)
15231 (x_get_window_property, receive_incremental_selection)

15246 Don't store size until memory allocation succeeds.
15247 (x_get_window_property): Plug memory leak on memory exhaustion.
15248 Don't double-block input; malloc is safe here. Don't assume 2**34
15249 - 4 fits in unsigned long. Add an xassert to check
15250 XGetWindowProperty overflow. Be more careful about overflow
15251 calculations, and distinguish size from memory overflow better.
15252 (receive_incremental_selection): When tracing, don't assume
15253 unsigned int is less than INT_MAX.
15254 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15255 harmful) conversions of unsigned short to int.

15257 in the range -65535 through -1 fit in an X unsigned short.
15258 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15259 result parameters unless successful. Rely on cons_to_unsigned
15260 to report problems with elements; the old code wasn't right anyway.
15261 (x_check_property_data): Check for int overflow; we cannot use
15262 a wider type due to X limits.
15263 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

15295 * lisp.h (hash_lookup, hash_put):
15296 * minibuf.c (Ftest_completion):
15297 Use ptrdiff_t for hash table indexes, not int (which is too
15298 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15299 32-bit --with-wide-int hosts).
15301 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15302 Add a FIXME comment about memory leaks.
15303 (syms_of_charset): Don't assume xmalloc returns.

15310 with outlandish widths.
15311 * character.h (sanitize_tab_width): Rename from sanitize_width,
15312 now that we have two such functions. All uses changed.

15330 * xterm.c: Don't go over XClientMessageEvent limit.
15331 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15332 (x_send_scroll_bar_event): Likewise. Check that the size does not
15333 exceed limits imposed by XClientMessageEvent, as well as the usual
15334 ptrdiff_t and size_t limits.
15336 * keyboard.c: Overflow, signedness and related fixes.
15337 (make_lispy_movement): Use same integer type in forward decl
15338 that is used in the definition.
15339 (read_key_sequence, keyremap_step):
15340 Change bufsize argument back to int, undoing my 2011-03-30 change.
15341 We prefer signed types, and int is wide enough here.
15342 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15343 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15344 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15345 length, not size_t. Use ptrdiff_t for index, not int.
15346 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15347 possibility of integer overflow.
15349 Overflow, signedness and related fixes for images.

15371 (lookup_image): Remove unnecessary tests.
15372 (xbm_image_p): Locals are now of int, not EMACS_INT,
15373 since parse_image_check makes sure they fit into int.
15374 (png_load, gif_load, svg_load_image):
15375 Prefer int to unsigned where either will do.
15376 (tiff_handler): New function, combining the cores of the
15377 old tiff_error_handler and tiff_warning_handler.
15378 This function is rewritten to use vsnprintf and thereby avoid
15379 stack buffer overflows. It uses only the features of vsnprintf
15380 that are common to both POSIX and native Microsoft.
15381 (tiff_error_handler, tiff_warning_handler): Use it.
15382 (tiff_load, gif_load, imagemagick_load_image):
15383 Don't assume :index value fits in 'int'.
15384 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15385 (imagemagick_load_image): Check that crop parameters fit into
15386 the integer types that MagickCropImage accepts. Don't assume
15387 Vimagemagick_render_type has a nonnegative value. Don't assume
15388 size_t fits in 'long'.
15389 (gs_load): Use printmax_t to print the widest integers possible.

15402 handle_single_display_spec, not just 1 or zero.
15403 (handle_single_display_spec): If the display spec is of the form
15404 `(space ...)', and specifies display in the text area, return 2
15406 (try_cursor_movement): Check for the need to scroll more
15407 accurately, and prefer exact match for point under bidi.
15408 Don't advance `row' beyond the last row of the window.

15426 buffers, return left-to-right.
15427 (set_cursor_from_row): Consider candidate row a win if its glyph
15428 represents a newline and point is on that newline. Fixes cursor
15429 positioning on the newline at EOL of R2L text within L2R
15430 paragraph, and vice versa.
15431 (try_cursor_movement): Check continued rows, in addition to
15432 continuation rows. Fixes unwarranted scroll when point enters a
15433 continued line of R2L text within an L2R paragraph, or vice versa.
15434 (cursor_row_p): Consider the case of point being equal to
15435 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15436 from the end of a short line to the beginning of a continued line
15437 of R2L text within L2R paragraph.

15465 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15466 candidate is selected by the mouse, and that candidate has a
15467 composed character under the mouse.
15469 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15470 coordinates reported by pos-visible-in-window-p for a composed
15471 character in column zero.

15479 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15480 consider it a hit if to_charpos is anywhere in the range of the
15481 composed buffer positions.
15483 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15485 * image.c (gif_load): Don't assume that each subimage has the same
15486 dimensions as the base image. Handle disposal method that is
15487 "undefined" by the gif spec (Bug#9335).
15489 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15491 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15501 a composition, take its buffer position from IT->cmp_it.charpos.
15502 Fixes cursor positioning at the beginning of a line that begins
15503 with a composed character.
15505 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15507 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15508 character bidirectional type, use STRONG_L instead. Fixes crashes
15509 in a buffer produced by `describe-categories'.
15511 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15512 members before the level stack, so they would be saved and
15513 restored when copying iterator state. Fixes incorrect reordering
15514 around TABs covered by display properties.

15601 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15602 the event loop. Get status from as_status (Bug#7276).
15604 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15605 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15606 the event loop (Bug#7276).
15608 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15610 * gnutls.c (QCgnutls_bootprop_priority)
15611 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
15612 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
15613 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
15614 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
15615 (QCgnutls_bootprop_verify_hostname_error)
15616 (QCgnutls_bootprop_callbacks_verify): Rename from
15617 Qgnutls_bootprop_..., all uses changed.
15619 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
15622 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
15624 * xfaces.c (Qframe_set_background_mode): Now static.
15625 * dispextern.h (Qframe_set_background_mode): Remove decl.
15627 * process.c (Fnetwork_interface_info): Declare local only if needed.
15629 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
15631 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15632 (Fnetwork_interface_list): Allocate in increments of bytes instead
15633 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15634 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15636 (struct ifflag_def): notrailers is smart on OSX.
15637 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15638 Get hardware address with getifaddrs if available.
15640 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15642 * xdisp.c (iterate_out_of_display_property): xassert that
15643 IT->position is set to within IT->object's boundaries. Break from
15644 the loop as soon as EOB is reached; avoids infloops in redisplay
15645 when IT->position is set up wrongly due to some bug.
15646 Set IT->current to match the bidi iterator unconditionally.
15647 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15648 entry. Force push_it to save on the stack the current
15649 buffer/string position, to be restored by pop_it. Fix flags in
15650 the iterator structure wrt the object coming from a display
15651 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15652 properties. (Bug#9284)
15654 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15656 * fontset.c (fontset_get_font_group): Add proper type checks.
15659 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15661 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
15662 and LC_VERSION_MIN_MACOSX.
15663 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
15664 (dump_it) [LC_FUNCTION_STARTS]: Use it.
15666 2011-08-08 Eli Zaretskii <eliz@gnu.org>
15668 * xdisp.c (forward_to_next_line_start): Allow to use the
15669 no-display-properties-and-no-overlays under bidi display.
15670 Set disp_pos in the bidi iterator to avoid searches for display
15671 properties and overlays.
15673 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15675 * editfns.c (Fset_time_zone_rule): Document relationship with the
15678 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
15679 the font entity extracted from the cache (Bug#8109).
15681 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15683 * composite.c (autocmp_chars): Don't reset point. That is done by
15684 restore_point_unwind (Bug#5984).
15686 2011-08-07 Juri Linkov <juri@jurta.org>
15688 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15689 to show the arg `TIME' instead of `TIMEVAL'.
15691 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15693 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15694 display property strides EOL and includes a newline, as in
15695 longlines-mode. (Bug#9254)
15696 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15697 word-wrap under bidirectional display. (Bug#9224)
15699 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15700 is non-zero, even if the data buffer is NULL. Fixes a crash in
15701 vertical-motion with longlines-mode. (Bug#9254)
15703 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15705 * bidi.c <bidi_cache_total_alloc>: Now static.
15706 (bidi_initialize): Initialize bidi_cache_total_alloc.
15708 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15711 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15712 amount allocated this far in `bidi_cache_total_alloc'.
15713 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15714 non-zero, only free the data buffer without restoring the cache
15715 contents. All callers changed.
15717 * dispextern.h (bidi_unshelve_cache): Update prototype.
15719 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15720 (move_it_in_display_line, move_it_to)
15721 (move_it_vertically_backward, move_it_by_lines): Replace the call
15722 to xfree to an equivalent call to bidi_unshelve_cache.
15723 (move_it_in_display_line_to): Fix logic of returning
15724 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15726 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15728 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15729 came from a string character with a `cursor' property. (Bug#9229)
15731 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15733 * Makefile.in (LIB_PTHREAD): New variable.
15734 (LIBES): Add LIB_PTHREAD (Bug#9216).
15736 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15737 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15739 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15741 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15743 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15745 * xterm.c (x_find_topmost_parent): New function.
15746 (x_set_frame_alpha): Find topmost parent window with
15747 x_find_topmost_parent and set the property there also (bug#9181).
15748 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15750 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15752 * callproc.c (Fcall_process): Avoid vfork clobbering
15753 the local vars buffer, coding_systems, current_dir.
15755 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15757 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15759 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15761 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15762 so that it is not optimized away.
15764 * xdisp.c (compute_display_string_pos): Remove unused local.
15766 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15768 Fix slow cursor motion and scrolling in large buffers with
15769 selective display, like Org Mode buffers. (Bug#9218)
15771 * dispextern.h (struct bidi_it): New member disp_prop_p.
15773 * xdisp.c: Remove one-slot cache of display string positions.
15774 (compute_display_string_pos): Accept an additional argument
15775 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15776 for a display string or property. If found, set DISP_PROP_P
15779 * bidi.c (bidi_fetch_char): Accept an additional argument
15780 DISP_PROP_P, and pass it to compute_display_string_pos.
15781 Only handle text covered by a display string if DISP_PROP_P is returned
15782 non-zero. All callers of bidi_fetch_char changed.
15784 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15786 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15788 2010-12-03 Don March <don@ohspite.net>
15790 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15791 last character M-[char] is translated to ESC [char] (bug#7541).
15793 2011-08-02 Kenichi Handa <handa@m17n.org>
15795 * lisp.h (uniprop_table): Extern it.
15797 * chartab.c (uniprop_table): Make it non-static.
15799 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15801 * xdisp.c (forward_to_next_line_start): Accept additional argument
15802 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15804 (reseat_at_next_visible_line_start): Use the bidi iterator state
15805 returned by forward_to_next_line_start to restore the state of
15806 it->bidi_it after backing up to previous newline. (Bug#9212)
15808 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15810 * regex.c (re_comp): Protoize.
15811 (re_exec): Fix return type.
15812 (regexec): Fix type of `ret'. (Bug#9203)
15814 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15816 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15817 This is needed if max-image-size is a floating-point number.
15819 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15821 * print.c (print_object): Print empty symbol as ##.
15823 * lread.c (read1): Read ## as empty symbol.
15825 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15827 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15828 setting frame foreground color (Bug#9175).
15829 (x_set_background_color): Likewise.
15831 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15832 contents (Bug#9176).
15833 (EmacsTooltip -init): Remove bezels and add shadows to
15836 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15837 or scroll bar (Bug#8470).
15839 * nsfont.m (nsfont_open): Remove assignment to voffset and
15840 unnecessary vars hshink, expand, hd, full_height, min_height.
15841 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15843 * nsterm.h (nsfont_info): Remove voffset field.
15845 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15847 Implement strike-through and overline on NextStep (Bug#8863).
15849 * nsfont.m (nsfont_open): Use underline position provided by font,
15850 instead of hard-coded value of 2.
15851 (nsfont_draw): Call ns_draw_text_decoration instead.
15853 * nsterm.h: Add declaration for ns_draw_text_decoration.
15855 * nsterm.m (ns_draw_text_decoration): New function for drawing
15856 underline, overline, and strike-through.
15857 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15858 ns_draw_text_decoration. Change treatment of cursor drawing to
15859 accommodate underlining, etc.
15861 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15863 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15866 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15868 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15869 Without this fix, if a signal arrives just after memory fills up,
15870 'malloc' might be invoked reentrantly.
15872 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15873 In other words, assume that every image size is allowed, on non-X
15874 hosts. This assumption is probably wrong, but it lets Emacs compile.
15876 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15878 * regex.c (re_iswctype): Convert return values to boolean.
15880 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15882 * xdisp.c (compute_display_string_pos): Don't use cached display
15883 string position if the buffer had its restriction changed.
15886 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15888 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15890 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15892 Integer signedness and overflow and related fixes. (Bug#9079)
15894 * bidi.c: Integer size and overflow fixes.
15895 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15896 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15897 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15898 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15899 (bidi_find_other_level_edge):
15900 Use ptrdiff_t instead of EMACS_INT where either will do.
15901 This works better on 32-bit hosts configured --with-wide-int.
15902 (bidi_cache_ensure_space): Check for size-calculation overflow.
15903 Use % rather than repeated addition, for better worst-case speed.
15904 Don't set bidi_cache_size until after xrealloc returns, because it
15906 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15907 (bidi_cache_ensure_space): Also check that the bidi cache size
15908 does not exceed that of the largest Lisp string or buffer. See Eli
15909 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15911 * alloc.c (__malloc_size_t): Remove.
15912 All uses replaced by size_t. See Andreas Schwab's note
15913 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15915 * image.c: Improve checking for integer overflow.
15916 (check_image_size): Assume that f is nonnull, since
15917 it is always nonnull in practice. This is one less thing to
15918 worry about when checking for integer overflow later.
15919 (x_check_image_size): New function, which checks for integer
15920 overflow issues inside X.
15921 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15922 This removes the need for a memory_full check.
15923 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15924 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15925 (xbm_read_bitmap_data): Change locals back to 'int', since
15926 their values must fit in 'int'.
15927 (xpm_load_image, png_load, tiff_load):
15928 Invoke x_create_x_image_and_pixmap earlier,
15929 to avoid much needless work if the image is too large.
15930 (tiff_load): Treat overly large images as if
15931 x_create_x_image_and_pixmap failed, not as malloc failures.
15932 (gs_load): Use x_check_image_size.
15934 * gtkutil.c: Omit integer casts.
15935 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15936 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15938 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15940 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15941 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15942 would wrongly return t on a 64-bit host.
15944 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15945 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15946 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15947 and therefore cause GCC to emit a bogus diagnostic in some cases.
15949 * image.c: Integer signedness and overflow and related fixes.
15950 This is not an exhaustive set of fixes, but it's time to
15951 record what I've got.
15952 (lookup_pixel_color, check_image_size): Remove redundant decls.
15953 (check_image_size): Don't assume that arbitrary EMACS_INT values
15954 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15955 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15956 (tiff_load, imagemagick_load_image):
15957 Check for overflow in size calculations.
15958 (x_create_x_image_and_pixmap): Remove unnecessary test for
15959 xmalloc returning NULL; that can't happen.
15960 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15961 (xpm_color_bucket): Use better integer hashing function.
15962 (xpm_cache_color): Don't possibly over-allocate memory.
15963 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15964 (gif_memory_source):
15965 Use ptrdiff_t, not int or size_t, to record sizes.
15966 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15967 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15968 either works, as we prefer signed integers.
15969 (tiff_read_from_memory, tiff_write_from_memory):
15970 Return tsize_t, not size_t, since that's what the TIFF API wants.
15971 (tiff_read_from_memory): Don't fail simply because the read would
15972 go past EOF; instead, return a short read.
15973 (tiff_load): Omit no-longer-needed casts.
15974 (Fimagemagick_types): Don't assume size fits into 'int'.
15976 Improve hashing quality when configured --with-wide-int.
15977 * fns.c (hash_string): New function, taken from sxhash_string.
15978 Do not discard information about ASCII character case; this
15979 discarding is no longer needed.
15980 (sxhash-string): Use it. Change sig to match it. Caller changed.
15981 * lisp.h: Declare it.
15982 * lread.c (hash_string): Remove, since we now use fns.c's version.
15983 The fns.c version returns a wider integer if --with-wide-int is
15984 specified, so this should help the quality of the hashing a bit.
15986 * emacs.c: Integer overflow minor fix.
15987 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15988 Define only if GNU_LINUX.
15989 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15991 * dispnew.c: Integer signedness and overflow fixes.
15992 Remove unnecessary forward decls, that were a maintenance hassle.
15993 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15995 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15996 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15997 (prepare_desired_row, line_draw_cost):
15998 Use int, not unsigned, where either works.
15999 (save_current_matrix, restore_current_matrix):
16000 Use ptrdiff_t, not size_t, where either works.
16001 (init_display): Check for overflow more accurately, and without
16002 relying on undefined behavior.
16004 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16005 Remove, replacing with the new symbols in lisp.h. All uses changed.
16006 * fileio.c (make_temp_name):
16007 * filelock.c (lock_file_1, lock_file):
16008 * xdisp.c (message_dolog):
16009 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16010 Use pMd etc. instead.
16011 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16012 replacing the pWIDE etc. symbols removed from editfns.c.
16014 * keyboard.h (num_input_events): Now uintmax_t.
16015 This is (very slightly) less likely to mess up due to wraparound.
16018 * buffer.c: Integer signedness fixes.
16019 (alloc_buffer_text, enlarge_buffer_text):
16020 Use ptrdiff_t rather than size_t when either will do, as we prefer
16023 * alloc.c: Integer signedness and overflow fixes.
16024 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16025 (__malloc_size_t): Default to size_t, not to int.
16026 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16027 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16028 Prefer ptrdiff_t to size_t when either would do, as we prefer
16030 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16031 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16032 Now const. Initialize with values that are in range even if char
16034 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16035 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16036 These functions do the right thing with sizes > 2**32.
16037 (check_depth): Now ptrdiff_t, not int.
16038 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16039 Adjust to new way of storing sizes. Check for size overflow bugs
16041 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16042 slightly wrong anyway, as it missed one instance of
16043 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16044 (refill_memory_reserve): Omit needless cast to size_t.
16045 (mark_object_loop_halt): Mark as externally visible.
16047 * xselect.c: Integer signedness and overflow fixes.
16048 (Fx_register_dnd_atom, x_handle_dnd_message):
16049 Use ptrdiff_t, not size_t, since we prefer signed.
16050 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16051 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16052 x_dnd_atoms_size and x_dnd_atoms_length.
16054 * doprnt.c: Prefer signed to unsigned when either works.
16056 * doprnt.c (doprnt):
16058 * xdisp.c (vmessage):
16059 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16060 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16061 prefer signed arithmetic to avoid comparison confusion.
16062 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16063 but is a bit tricky.
16065 Assume freestanding C89 headers, string.h, stdlib.h.
16066 * data.c, doprnt.c, floatfns.c, print.c:
16067 Include float.h unconditionally.
16068 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16069 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16070 * regex.c: Likewise for stddef.h, string.h.
16071 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16072 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16073 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16074 (STDC_HEADERS): Remove obsolete defines.
16075 * sysdep.c: Include limits.h unconditionally.
16077 Assume support for memcmp, memcpy, memmove, memset.
16078 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16079 * regex.c (memcmp, memcpy):
16080 Remove; we assume C89 now.
16082 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16083 (__malloc_safe_bcopy): Remove; no longer needed.
16085 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16086 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16087 well either way, and we prefer signed to unsigned.
16089 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16091 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16092 closes the connection while we're reading (bug#9182).
16094 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16096 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16097 are specified (Bug#9168).
16099 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16101 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16102 Found by GCC static checking and --with-wide-int on a 32-bit host.
16104 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16106 * xdisp.c (compute_display_string_pos): Fix logic of caching
16107 previous display string position. Initialize cached_prev_pos to
16108 -1. Fixes slow-down at the beginning of a buffer.
16110 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16112 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16113 for attrs[LFACE_FONTSET_INDEX].
16115 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16117 * xml.c (parse_region): Remove unused local
16118 that was recently introduced.
16120 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16122 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16123 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16125 * xdisp.c (move_it_in_display_line_to): Record the best matching
16126 position for TO_CHARPOS while scanning the line, and restore it on
16127 exit if none of the characters scanned was an exact match.
16128 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16129 when exact match is impossible due to invisible text, and the
16130 lines are truncated.
16132 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16134 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16137 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16139 Fix a significant slow-down of cursor motion with C-n, C-p,
16140 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16141 auto-repeat under bidi redisplay in fontified buffers.
16142 * xdisp.c (compute_stop_pos_backwards): New function.
16143 (next_element_from_buffer): Call compute_stop_pos_backwards to
16144 find a suitable prev_stop when we find ourselves before
16146 (reseat): Don't look for prev_stop, as that could mean a very long
16148 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16149 <cached_disp_overlay_modiff>: Cache for last found display string
16151 (compute_display_string_pos): Return the cached position if asked
16152 about the same buffer in the same area of character positions, and
16153 the buffer wasn't changed since the time the display string
16154 position was cached.
16156 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16158 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16159 is an integer, which is important for empty lines. (Bug#9149)
16161 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16163 * frame.c (Fmodify_frame_parameters): In tty case, update the
16164 default face if necessary (Bug#4238).
16166 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16168 * editfns.c (Fstring_to_char): No need to explain what a character
16169 is in the docstring (Bug#6576).
16171 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16173 * xml.c (parse_region): Make sure we always return a tree.
16175 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16177 * xml.c (parse_region): If a document contains only comments,
16180 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16182 * xml.c (make_dom): Return comments, too.
16184 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16187 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16188 and the surrounding thread.
16189 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16190 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16191 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16193 * s/openbsd.h (BROKEN_SIGIO): Define.
16194 * unexelf.c (unexec) [__OpenBSD__]:
16195 Don't update the .mdebug section of the Alpha COFF symbol table.
16197 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16199 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16202 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16204 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16205 This fixes some race conditions on the permissions of any newly
16208 * alloc.c (valid_pointer_p): Use pipe, not open.
16209 This fixes some permissions issues when debugging.
16211 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16212 If fchown fails to set both uid and gid, try to set just gid,
16213 as that is sometimes allowed. Adjust the file's mode to eliminate
16214 setuid or setgid bits that are inappropriate if fchown fails.
16216 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16218 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16219 to compare Lisp_Objects.
16220 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16221 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16222 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16224 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16226 * lread.c (read_integer): Unread even EOF character.
16227 (read1): Likewise. Properly record start position of symbol.
16229 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16230 symbol character follows.
16232 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16234 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16235 This works around a problem with the previous change to Fcopy_file.
16236 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16237 and without this change, GCC might complain about discarding
16238 fchown's return value.
16240 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16242 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16244 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16246 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16248 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16250 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16251 it's used from the C level.
16253 * process.c: Use the same condition for POLL_FOR_INPUT in both
16254 keyboard.c and process.c (bug#1858).
16256 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16258 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16259 (Fgnutls_boot): Use it.
16261 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16263 * doc.c (Fsubstitute_command_keys): Revert last change.
16265 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16267 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16268 quotes the next character, and doesn't affect other longer
16269 sequences (bug#8935).
16271 * lread.c (syms_of_lread): Clarify that is isn't only
16272 `eval-buffer' and `eval-defun' that's affected by
16273 `lexical-binding' (bug#8460).
16275 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16277 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16278 bidi redisplay when a line includes both an image and is truncated.
16280 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16282 Fix minor problems found by static checking.
16283 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16284 (elsz): Now a signed constant, not a size_t var. We prefer signed
16285 types to unsigned, to avoid integer comparison confusion. Without
16286 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16287 "cannot optimize loop, the loop counter may overflow", a symptom
16289 * indent.c (Fvertical_motion): Mark locals as initialized.
16290 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16292 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16294 * search.c (Fre_search_backward): Mention `case-fold-search' in
16295 all the re_search_* functions (bug#8138).
16297 * keyboard.c (Fopen_dribble_file): Document when the file is

16308 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
16309 (reseat_to_string): Initialize bidi_it->string.s and
16310 bidi_it->string.schars.
16311 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16312 NULL (avoids a crash in bidi_paragraph_init).
16313 Initialize itb.string.lstring.
16314 (init_iterator): Call bidi_init_it only of a valid
16315 buffer position was specified. Initialize paragraph_embedding to
16317 (reseat_to_string): Initialize the bidi iterator.
16318 (display_string): If we need to ignore text properties of
16319 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16320 original value of -1 will not work with bidi.)
16321 (compute_display_string_pos): First arg is now struct
16322 `text_pos *'; all callers changed. Support display properties on
16324 (compute_display_string_end): Support display properties on Lisp
16326 (init_iterator, reseat_1, reseat_to_string): Initialize the
16327 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16328 when iterating on a string not from display properties).
16329 (compute_display_string_pos, compute_display_string_end):
16330 Fix calculation of the object to scan. Fixes an error when using
16332 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16333 base_level_stop; instead, set base_level_stop to BEGV.
16334 Fixes crashes in vertical-motion.
16335 (next_element_from_buffer): Improve commentary for when
16336 the iterator is before prev_stop.
16337 (init_iterator): Initialize bidi_p from the default value of
16338 bidi-display-reordering, not from buffer-local value. Use the
16339 buffer-local value only if initializing for buffer iteration.
16340 (handle_invisible_prop): Support invisible properties on strings
16341 that are being bidi-reordered.
16342 (set_iterator_to_next): Support bidi reordering of C strings and
16344 (next_element_from_string): Support bidi reordering of Lisp
16346 (handle_stop_backwards): Support Lisp strings as well.
16347 (display_string): Support display of R2L glyph rows.
16348 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16349 (init_iterator): Don't initialize it->bidi_p for strings
16351 (reseat_to_string): Initialize it->bidi_p for strings here.
16352 (next_element_from_string, next_element_from_c_string)
16353 (next_element_from_buffer): Add xassert's for correspondence
16354 between IT's object being iterated and it->bidi_it.string

16357 (next_element_from_c_string): Handle the case of the first string
16358 character that is not the first one in the visual order.
16359 (get_visually_first_element): New function, refactored from common
16360 parts of next_element_from_buffer, next_element_from_string, and
16361 next_element_from_c_string.
16362 (tool_bar_lines_needed, redisplay_tool_bar)
16363 (display_menu_bar): Force left-to-right direction. Add a FIXME
16364 comment for making that be controlled by a user option.
16365 (push_it, pop_it): Save and restore the state of the
16366 bidi iterator. Save and restore the bidi_p flag.
16367 (pop_it): Iterate out of display property for string iteration as
16369 (iterate_out_of_display_property): Support iteration over strings.
16370 (handle_single_display_spec): Set up it->bidi_it for iteration
16371 over a display string, and call bidi_init_it.
16372 (handle_single_display_spec, next_overlay_string)
16373 (get_overlay_strings_1, push_display_prop): Set up the bidi
16374 iterator for displaying display or overlay strings.
16375 (forward_to_next_line_start): Don't use the shortcut if
16377 (back_to_previous_visible_line_start): If handle_display_prop
16378 pushed the iterator stack, restore the internal state of the bidi
16379 iterator by calling bidi_pop_it same number of times.
16380 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16381 and we are bidi-iterating, don't decrement the iterator position;
16382 instead, set the first_elt flag in the bidi iterator, to produce
16384 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16385 (push_display_prop): xassert that we are iterating a buffer.
16386 (push_it, pop_it): Save and restore paragraph_embedding member.
16387 (handle_single_display_spec, next_overlay_string)
16388 (get_overlay_strings_1, reseat_1, reseat_to_string)
16389 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16390 correctly. Don't assume unibyte strings are not bidi-reordered.
16391 (compute_display_string_pos)
16392 (compute_display_string_end): Fix handling the case of C string.
16393 (push_it, pop_it): Save and restore from_disp_prop_p.

16398 popping after iteration over a string that came from a display
16399 property. Fix a typo in popping stretch info. Add an assertion
16400 for verifying that the iterator position is in sync with the bidi
16402 (handle_single_display_spec, get_overlay_strings_1)
16403 (push_display_prop): Fix initialization of paragraph direction for
16404 string when that of the parent object is not yet determined.
16405 (reseat_1): Call bidi_init_it to resync the bidi
16406 iterator with IT's position. (Bug#7616)
16407 (find_row_edges): If ROW->start.pos gives position
16408 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
16409 (handle_stop, back_to_previous_visible_line_start, reseat_1):
16410 Reset the from_disp_prop_p flag.
16411 (SAVE_IT, RESTORE_IT): New macros.

16413 (back_to_previous_visible_line_start)
16414 (move_it_in_display_line_to, move_it_in_display_line)
16415 (move_it_to, move_it_vertically_backward, move_it_by_lines)
16416 (try_scrolling, redisplay_window, display_line): Use them when
16417 saving a temporary copy of the iterator and restoring it back.
16418 (back_to_previous_visible_line_start, reseat_1)
16419 (init_iterator): Empty the bidi cache "stack".
16420 (move_it_in_display_line_to): If iterator ended up at
16421 EOL, but we never saw any buffer positions smaller than
16422 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16423 motion in bidi-reordered lines.
16424 (move_it_in_display_line_to): Record prev_method and prev_pos
16425 immediately before the call to set_iterator_to_next. Fixes cursor
16426 motion in bidi-reordered lines with stretch glyphs and strings
16427 displayed in margins. (Bug#8133) (Bug#8867)
16428 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16430 (pos_visible_p): Support positions in bidi-reordered lines.
16431 Save and restore bidi cache.
16433 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16434 (bidi_paragraph_info): Delete unused struct.
16435 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
16436 (bidi_cache_start): New variable.
16437 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
16439 (bidi_cache_fetch_state, bidi_cache_search)
16440 (bidi_cache_find_level_change, bidi_cache_iterator_state)

16445 (bidi_fetch_char): Accept new argument STRING; all callers
16446 changed. Support iteration over a string. Support strings with
16447 display properties. Support unibyte strings. Fix the type of
16448 `len' according to what STRING_CHAR_AND_LENGTH expects.
16449 (bidi_paragraph_init, bidi_resolve_explicit_1)
16450 (bidi_resolve_explicit, bidi_resolve_weak)
16451 (bidi_level_of_next_char, bidi_move_to_visually_next):
16452 Support iteration over a string.
16453 (bidi_set_sor_type, bidi_resolve_explicit_1)
16454 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16455 can now be zero (for strings); special values 0 and -1 were
16456 changed to -1 and -2, respectively.
16457 (bidi_char_at_pos): New function.
16458 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
16459 Call it instead of FETCH_MULTIBYTE_CHAR.

16469 (bidi_initialize): Initialize the bidi cache start stack pointer.
16470 (bidi_cache_ensure_space): New function, refactored from part of

16544 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16546 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16547 The old code sometimes used this field without initializing it.
16549 * alloc.c (gc_sweep): Don't read past end of array.
16550 In theory, the old code could also have corrupted Emacs internals,
16551 though it'd be very unlikely.

16654 Use pthread_sigmask, not sigprocmask (Bug#9010).
16655 sigprocmask is portable only for single-threaded applications, and
16656 Emacs can be multi-threaded when it uses GTK.

16814 (clone_per_buffer_values): Don't assume that

16816 This isn't true in general, and it's particularly not true
16817 if Emacs is configured with --with-wide-int.
16818 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16819 New macros, used in the buffer.c change.

16855 Random fixes. E.g., (random) never returned negative values.
16856 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16857 subseconds part to the entropy, as that's a bit more random.
16858 Prefer signed to unsigned, since the signedness doesn't matter and
16859 in general we prefer signed. When given a limit, use a
16860 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16861 latter isn't right if USE_2_TAGS_FOR_INTS.
16862 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16863 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16875 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16876 This is more efficient than Ffile_directory_p and avoids a minor race.
16878 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16880 * buffer.c (Foverlay_put): Say what the return value is
16883 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16884 is a directory before asking whether to use the file name
16886 (barf_or_query_if_file_exists): Make the "File is a directory"
16887 error be more correct.
16889 * fns.c (Frequire): Remove the mention of the .gz files, since
16890 that's installation-specific, but keep the mention of
16891 `get-load-suffixes'.

16895 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

16903 Qgnutls_bootprop_verify_error (which is no longer used).
16905 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16906 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16907 Also (re)move comments that are misplaced or no longer relevant.
16909 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16911 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
16913 2011-07-03 Chong Yidong <cyd@stupidchicken.com>

17008 * eval.c (struct backtrace): Simplify and port the data structure.
17009 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17010 signed bit field, as this assumption is not portable and it makes
17011 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17012 "char debug_on_exit : 1" as this is not portable either; instead,
17013 use the portable "unsigned int debug_on_exit : 1". Remove unused
17014 member evalargs. Remove obsolete comments about cc bombing out.

17201 (read_integer): Radix is now EMACS_INT, not int,
17202 to improve quality of diagnostics for out-of-range radices.
17203 Calculate buffer size correctly for out-of-range radices.
17204 (read1): Check for integer overflow in radices, and in
17205 read-circle numbers.
17206 (read_escape): Avoid int overflow.
17207 (Fload, openp, read_buffer_size, read1)
17208 (substitute_object_recurse, read_vector, read_list, map_obarray):

17249 on undefined behavior with wrong number of arguments.
17250 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17251 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17252 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17253 since we're not interested in debugging glyphs with old libraries.
17254 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17255 GCC 4.6.0's static checking.

17296 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17297 (x_session_initialize): Do not assume string length fits in int.
17299 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

17325 * minibuf.c (Fread_buffer):
17326 * lread.c (intern, intern_c_string):
17327 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

17345 Don't assume pid_t and time_t fit in unsigned long.
17346 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17347 (current_lock_owner): Prefer signed type for sizes.
17348 Use memcpy, not strncpy, where memcpy is what is really wanted.
17349 Don't assume (via atoi) that time_t and pid_t fit in int.
17350 Check for time_t and/or pid_t out of range, e.g., via a network share.
17351 Don't alloca where an auto var works fine.

17357 (make_temp_name): Don't assume pid fits in int, or that its print
17358 length is less than 20.
17360 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17362 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17364 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17366 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17367 We prefer signed integers, even for size calculations.
17369 * emacs.c: Don't assume string length fits in 'int'.
17370 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17371 (main): Don't invoke strlen when not needed.
17373 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17374 (XD_DEBUG_MESSAGE): Don't waste a byte.
17376 * callproc.c (getenv_internal_1, getenv_internal)
17377 (Fgetenv_internal):
17378 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17380 * lread.c (invalid_syntax): Omit length argument.
17381 All uses changed. This doesn't fix a bug, but it simplifies the
17382 code away from its former Hollerith-constant appearance, and it's
17383 one less 'int' to worry about when looking at integer-overflow issues.
17384 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17386 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17387 This didn't break anything, but it didn't help either.
17388 It's confusing to put a bogus integer in a place where the actual
17389 value does not matter.
17390 (LIST_END_P): Remove unused macro and its bogus comment.
17391 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17393 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17394 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17396 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17397 We prefer signed types, and the value cannot exceed the EMACS_INT
17398 range anyway (because otherwise the length would not be representable).
17399 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17400 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17401 This avoids a GCC warning when WIDE_EMACS_INT.
17403 * indent.c (sane_tab_width): New function.
17404 (current_column, scan_for_column, Findent_to, position_indentation)
17405 (compute_motion): Use it. This is just for clarity.
17406 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17408 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17410 * lisp.h (lint_assume): New macro.
17411 * composite.c (composition_gstring_put_cache):
17412 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17414 * editfns.c, insdel.c:
17415 Omit unnecessary forward decls, to simplify future changes.
17417 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17419 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17421 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17422 Use much-faster test for byte-length change.
17423 Don't assume string byte-length fits in 'int'.
17424 Check that character arg fits in 'int'.
17425 (mapcar1): Declare byte as byte, for clarity.
17427 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17429 * fns.c (concat): Catch string overflow earlier.
17430 Do not rely on integer wraparound.
17432 * dispextern.h (struct it.overlay_strings_charpos)
17433 (struct it.selective): Now EMACS_INT, not int.
17434 * xdisp.c (forward_to_next_line_start)
17435 (back_to_previous_visible_line_start)
17436 (reseat_at_next_visible_line_start, next_element_from_buffer):
17437 Don't arbitrarily truncate the value of 'selective' to int.
17439 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17441 * composite.c: Don't truncate sizes to 'int'.
17442 (composition_gstring_p, composition_reseat_it)
17443 (composition_adjust_point): Use EMACS_INT, not int.
17444 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17445 not EMACS_UINT, for indexes.
17447 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17449 * buffer.c: Include <verify.h>.
17450 (struct sortvec.priority, struct sortstr.priority):
17451 Now EMACS_INT, not int.
17452 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17453 (struct sortstr.size, record_overlay_string)
17454 (struct sortstrlist.size, struct sortlist.used):
17455 Don't truncate size to int.
17456 (record_overlay_string): Check for size-calculation overflow.
17457 (init_buffer_once): Check at compile-time, not run-time.
17459 2011-06-22 Jim Meyering <meyering@redhat.com>
17461 Don't leak an XBM-image-sized buffer
17462 * image.c (xbm_load): Free the image buffer after using it.
17464 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17467 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17468 that Sun C diagnosed.
17469 * fns.c (secure_hash): Fix pointer signedness issue.
17470 * intervals.c (static_offset_intervals): New function.
17471 (offset_intervals): Use it.
17473 2011-06-21 Leo Liu <sdl.web@gmail.com>
17476 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17479 * fns.c (secure_hash): Rename from crypto_hash_function and change
17480 the first arg to accept symbols.
17481 (Fsecure_hash): New primitive.
17482 (syms_of_fns): New symbols.
17484 2011-06-20 Deniz Dogan <deniz@dogan.se>
17486 * process.c (Fset_process_buffer): Clarify return value in
17489 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17491 * dispnew.c (add_window_display_history): Use BVAR.
17493 * xdisp.c (debug_method_add): Use BVAR.
17494 (check_window_end, dump_glyph_matrix, dump_glyph)
17495 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17497 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17500 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17501 check till after the cache is created in init_frame_faces.
17503 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17505 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17507 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17509 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17510 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17511 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17513 Improve buffer-overflow checking (Bug#8873).
17514 * fileio.c (Finsert_file_contents):
17515 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17516 Remove the old (too-loose) buffer overflow checks.
17517 They weren't needed, since make_gap checks for buffer overflow.
17518 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17519 The old code merely checked for Emacs fixnum overflow, and relied
17520 on undefined (wraparound) behavior. The new code avoids undefined
17521 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17523 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17524 Tune. Don't use wider integers than needed. Don't use alloca.
17525 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17527 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17529 * insdel.c, lisp.h (buffer_overflow): New function.
17530 (insert_from_buffer_1, replace_range, replace_range_2):
17531 * insdel.c (make_gap_larger):
17532 * editfns.c (Finsert_char):
17533 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17535 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17537 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17539 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17541 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17542 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17544 * fileio.c: Don't assume EMACS_INT fits in off_t.
17545 (emacs_lseek): New static function.
17546 (Finsert_file_contents, Fwrite_region): Use it.
17547 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17549 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17551 * fns.c: Don't overflow int when computing a list length.
17552 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17553 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17554 truncation on 64-bit hosts. Check for QUIT every
17555 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17556 faster and is responsive enough.
17557 (Flength): Report an error instead of overflowing an integer.
17558 (Fsafe_length): Return a float if the value is not representable
17559 as a fixnum. This shouldn't happen except in contrived situations.
17560 (Fnthcdr, Fsort): Don't assume list length fits in int.
17561 (Fcopy_sequence): Don't assume vector length fits in int.
17563 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17564 (header_size, word_size): New constants.
17565 (allocate_vectorlike): Don't check size overflow here.
17566 (allocate_vector): Check it here instead, since this is the only
17567 caller of allocate_vectorlike that could cause overflow.
17568 Check that the new vector's length is representable as a fixnum.
17570 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17571 The previous code was bogus. For example, next_almost_prime (32)
17572 returned 39, which is undesirable as it is a multiple of 3; and
17573 next_almost_prime (24) returned 25, which is a multiple of 5 so
17574 why was the code bothering to check for multiples of 7?
17576 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17578 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17580 Variadic C functions now count arguments with ptrdiff_t.
17581 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17582 Back then I didn't know that the Emacs coding style prefers signed int.
17583 Also, in the meantime I found a few more instances where arguments
17584 were being counted with int, which may truncate counts on 64-bit
17585 machines, or EMACS_INT, which may be unnecessarily wide.
17586 * lisp.h (struct Lisp_Subr.function.aMANY)
17587 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17588 Arg counts are now ptrdiff_t, not size_t.
17589 All variadic functions and their callers changed accordingly.
17590 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17591 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17592 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17593 * callint.c (Fcall_interactively): Check arg count for overflow,
17594 to avoid potential buffer overrun. Use signed char, not 'int',
17595 for 'varies' array, so that we needn't bother to check its size
17596 calculation for overflow.
17597 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17598 * eval.c (apply_lambda):
17599 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17600 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17601 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17603 * callint.c (Fcall_interactively): Don't use index var as event count.
17605 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17606 * mem-limits.h (SIZE): Remove; no longer used.
17608 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17610 Remove unnecessary casts.
17611 * xterm.c (x_term_init):
17612 * xfns.c (x_set_border_pixel):
17613 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17614 These aren't needed now that we assume ANSI C.
17616 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17617 It's more likely to cause problems (due to unsigned overflow)
17620 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17622 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17624 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17626 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17628 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17630 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17632 GLYPH_CODE_FACE returns EMACS_INT, not int.
17633 * dispextern.h (merge_faces):
17634 * xfaces.c (merge_faces):
17635 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17636 Don't assume EMACS_INT fits in int.
17638 * character.h (CHAR_VALID_P): Remove unused parameter.
17639 * fontset.c, lisp.h, xdisp.c: All uses changed.
17641 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17643 * fns.c (concat): Minor tuning based on overflow analysis.
17644 This doesn't fix any bugs. Use int to hold character, instead
17645 of constantly refetching from Emacs object. Use XFASTINT, not
17646 XINT, for value known to be a character. Don't bother comparing
17647 a single byte to 0400, as it's always less.
17649 * floatfns.c (Fexpt):
17650 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17652 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17655 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17657 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17658 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17659 incorrectly succeed when S was a string, because 4294967386 was
17660 truncated before it was used.
17662 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17663 Otherwise, an out-of-range integer could cause undefined behavior
17666 * composite.c: Use int, not EMACS_INT, for characters.
17667 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17668 EMACS_INT, for values that are known to be in character range.
17669 This doesn't fix any bugs but is the usual style inside Emacs and
17670 may generate better code on 32-bit machines.
17672 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17673 This is for reasons similar to the recent CHAR_STRING fix.
17674 * charset.c (Fencode_char): Check that character arg is actually
17675 a character. Pass an int to ENCODE_CHAR.
17676 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17677 wider than 'int', as a compile-time check to prevent future regressions
17680 * character.c (char_string): Remove unnecessary casts.
17682 Make sure a 64-bit char is never passed to CHAR_STRING.
17683 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17684 by silently ignoring the top 32 bits, allowing some values
17685 that were far too large to be valid characters.
17686 * character.h: Include <verify.h>.
17687 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17688 arguments are no wider than unsigned, as a compile-time check
17689 to prevent future regressions in this area.
17691 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17692 (Fsubst_char_in_region):
17694 * xdisp.c (decode_mode_spec_coding):
17695 Adjust to CHAR_STRING's new requirement.
17696 * editfns.c (Finsert_char, Fsubst_char_in_region):
17697 * fns.c (concat): Check that character args are actually
17698 characters. Without this test, these functions did the wrong
17699 thing with wildly out-of-range values on 64-bit hosts.
17701 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17702 These casts should not be needed on 32-bit hosts, either.
17703 * keyboard.c (read_char):
17704 * lread.c (Fload): Remove casts to unsigned.
17706 * lisp.h (UNSIGNED_CMP): New macro.
17707 This fixes comparison bugs on 64-bit hosts.
17708 (ASCII_CHAR_P): Use it.
17709 * casefiddle.c (casify_object):
17710 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17711 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17712 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17713 * dispextern.h (FACE_FROM_ID):
17714 * keyboard.c (read_char): Use UNSIGNED_CMP.
17716 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17717 not to EMACS_INT, to avoid GCC warning.
17719 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17721 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17722 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17723 isn't needed on 32-bit machines.
17725 * buffer.c (Fgenerate_new_buffer_name):
17726 Use EMACS_INT for count, not int.
17727 (advance_to_char_boundary): Return EMACS_INT, not int.
17729 * data.c (Qcompiled_function): Now static.
17731 * window.c (window_body_lines): Now static.
17733 * image.c (gif_load): Rename local to avoid shadowing.
17735 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17736 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17737 * alloc.c (make_save_value): Integer argument is now of type
17738 ptrdiff_t, not int.
17739 (mark_object): Use ptrdiff_t, not int.
17740 * lisp.h (pD): New macro.
17741 * print.c (print_object): Use it.
17743 * alloc.c: Use EMACS_INT, not int, to count objects.
17744 (total_conses, total_markers, total_symbols, total_vector_size)
17745 (total_free_conses, total_free_markers, total_free_symbols)
17746 (total_free_floats, total_floats, total_free_intervals)
17747 (total_intervals, total_strings, total_free_strings):
17748 Now EMACS_INT, not int. All uses changed.
17749 (Fgarbage_collect): Compute overall total using a double, so that
17750 integer overflow is less likely to be a problem. Check for overflow
17751 when converting back to an integer.
17752 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17753 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17754 These were 'int' variables that could overflow on 64-bit hosts;
17755 they were never used, so remove them instead of repairing them.
17756 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17757 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17758 Previously, this ceilinged at INT_MAX, but that doesn't work on
17760 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17762 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17763 (allocate_vectorlike): Check for ptrdiff_t overflow.
17764 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17765 when a (possibly-narrower) signed value would do just as well.
17766 We prefer using signed arithmetic, to avoid comparison confusion.
17768 * alloc.c: Catch some string size overflows that we were missing.
17769 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17770 for convenience in STRING_BYTES_MAX.
17771 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17772 The definition here is exact; the one in lisp.h was approximate.
17773 (allocate_string_data): Check for string overflow. This catches
17774 some instances we weren't catching before. Also, it catches
17775 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17776 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17777 and ptrdiff_t and EMACS_INT are both 64 bits.
17779 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17780 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17781 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17783 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17785 * alloc.c (Fmake_string): Check for out-of-range init.
17787 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17789 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17791 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17793 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17794 xg_get_default_scrollbar_width.
17796 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17797 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17798 (style_changed_cb): Call update_theme_scrollbar_width and call

18278 (Fset_frame_selected_window): Move here from frame.c.
18280 (Fselected_window, select_window, Fselect_window): Move up in
18281 code. Minor doc-string fixes.
18283 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
18285 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18286 Do not assume that spare memory exists; that assumption is valid
18287 only if SYSTEM_MALLOC.
18288 (LARGE_REQUEST): New macro, so that the issue of large requests
18289 is separated from the issue of spare memory.
18291 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
18293 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

18319 New error handlers.
18320 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
18321 Obey Vx_select_enable_clipboard_manager. Catch errors in

18323 (Vx_select_enable_clipboard_manager): New variable.
18324 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).

18330 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18332 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap

18341 Support bidi reordering of text covered by display properties.
18343 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18344 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18345 (bidi_cache_search, bidi_cache_iterator_state)
18346 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18347 (bidi_level_of_next_char, bidi_move_to_visually_next):
18348 Support character positions inside a run of characters covered by a
18350 (bidi_paragraph_init, bidi_resolve_explicit_1)
18351 (bidi_level_of_next_char): Call bidi_fetch_char and
18352 bidi_fetch_char_advance instead of FETCH_CHAR and
18353 FETCH_CHAR_ADVANCE.

18355 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18357 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18358 instead of using explicit *_CHAR codes.
18359 (bidi_resolve_explicit, bidi_resolve_weak):
18360 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18361 bidirectional text is supported only in multibyte buffers.
18362 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18363 it to initialize the frame_window_p member of struct bidi_it.
18364 (bidi_cache_iterator_state, bidi_resolve_explicit_1)

18367 bidi_it->nchars is non-positive.
18368 (bidi_level_of_next_char): Don't try to lookup the cache for the
18369 next/previous character if nothing is cached there yet, or if we
18370 were just reseat()'ed to a new position.
18372 * xdisp.c (set_cursor_from_row): Set start and stop points
18373 according to the row's direction when priming the loop that looks
18374 for the glyph on which to display cursor.
18375 (single_display_spec_intangible_p): Function deleted.
18376 (display_prop_intangible_p): Reimplement to call
18377 handle_display_spec instead of single_display_spec_intangible_p.
18378 Accept 3 additional arguments needed by handle_display_spec.
18379 This fixes incorrect cursor motion across display property with complex
18380 values: lists, `(when COND...)' forms, etc.
18381 (single_display_spec_string_p): Support property values that are
18382 lists with the argument STRING its top-level element.
18383 (display_prop_string_p): Fix the condition for processing a
18384 property that is a list to be consistent with handle_display_spec.
18385 (handle_display_spec): New function, refactored from the
18386 last portion of handle_display_prop.
18387 (compute_display_string_pos): Accept additional argument
18388 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18389 value of a `display' property is a "replacing spec".
18390 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18391 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18392 the display property, but just return a value indicating whether
18393 the display property will replace the characters it covers.
18394 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18395 frame_window_p members of struct bidi_it.
18396 (compute_display_string_pos, compute_display_string_end):
18398 (push_it): Accept second argument POSITION, where pop_it should
18399 jump to continue iteration.
18400 (reseat_1): Initialize bidi_it.disp_pos.
18402 * keyboard.c (adjust_point_for_property): Adjust the call to
18403 display_prop_intangible_p to its new signature.
18405 * dispextern.h (struct bidi_it): New member frame_window_p.
18406 (bidi_init_it): Update prototypes.
18407 (display_prop_intangible_p): Update prototype.
18408 (compute_display_string_pos, compute_display_string_end):
18409 Declare prototypes.
18410 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18413 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18415 Malloc failure behavior now depends on size of allocation.
18416 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18417 * lisp.h: Change signatures accordingly.
18418 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18419 All callers changed. (Bug#8762)
18421 * gnutls.c: Use Emacs's memory allocators.
18422 Without this change, the gnutls library would invoke malloc etc.
18423 directly, which causes problems on non-SYNC_INPUT hosts, and which
18424 runs afoul of improving memory_full behavior. (Bug#8761)
18425 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18426 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18427 xfree instead of the default malloc, realloc, free.
18428 (Fgnutls_boot): No need to check for memory allocation failure,
18429 since xmalloc does that for us.
18431 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18432 * category.c (hash_get_category_set):
18433 * ccl.c (ccl_driver):
18434 * charset.c (Fdefine_charset_internal):

18445 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18446 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18447 * image.c (make_image, search_image_cache, lookup_image)
18448 (xpm_put_color_table_h):
18449 * lisp.h (struct Lisp_Hash_Table):
18450 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18451 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18452 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18453 * alloc.c (allocate_vectorlike):
18454 Check for overflow in vector size calculations.
18455 * ccl.c (ccl_driver):
18456 Check for overflow when converting EMACS_INT to int.
18457 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18458 need to be updated by these changes.
18459 * fns.c (make_hash_table, maybe_resize_hash_table):
18460 Check for integer overflow with large hash tables.
18461 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18462 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18463 (SXHASH_REDUCE): New macro.
18464 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18465 Use it instead of discarding useful hash info with large hash values.
18466 (sxhash_float): New function.
18467 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18468 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18469 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18470 Rewrite to use FIXNUM_BITS, as this simplifies things.
18471 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18472 Adjust signatures to match updated version of code.
18473 (consing_since_gc): Now EMACS_INT, since a single hash table can
18474 use more than INT_MAX bytes.
18476 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18478 Make it possible to build with GCC-4.6+ -O2 -flto.
18480 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18482 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18484 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18485 Call minibuffer-inactive-mode.
18487 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18489 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18490 Update dependencies.
18492 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18494 * data.c (init_data): Remove code for UTS, this system is not
18497 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18499 Don't force ./temacs to start in terminal mode.
18501 * frame.c (make_initial_frame): Initialize faces in all cases, not
18502 only when CANNOT_DUMP is defined.
18503 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18505 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18507 * dispnew.c (add_window_display_history): Use const for the string
18508 pointer. Remove declaration, not needed.
18510 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18512 Use 'inline', not 'INLINE'.
18513 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18514 * alloc.c, fontset.c (INLINE): Remove.
18515 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18516 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18517 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18518 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18519 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18521 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18523 Make it possible to run ./temacs.
18525 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18526 syms_of_callproc does the same thing. Remove test for
18527 "initialized", do it in the caller.
18528 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18530 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18532 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18533 (read_minibuf): Use get_minibuffer.
18534 (syms_of_minibuf): Use DEFSYM.
18535 (Qmetadata): New var.
18536 * data.c (Qbuffer): Don't make it static.
18537 (syms_of_data): Use DEFSYM.
18539 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18541 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18542 (CCL_CODE_MIN): New macro.
18544 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18546 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18548 * eval.c (Qdebug): Now static.
18549 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18550 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18551 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18553 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18555 * image.c: Various fixes to ImageMagick code comments.
18556 (Fimagemagick_types): Doc fix.
18558 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18560 Minor fixes prompted by GCC 4.6.0 warnings.
18562 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18564 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18565 (x_clipboard_manager_save_all): Move extern decl to ...
18566 * xterm.h: ... here, so that it can be checked for consistency.
18568 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18570 * xselect.c (x_clipboard_manager_save_frame)
18571 (x_clipboard_manager_save_all): New functions.
18572 (Fx_clipboard_manager_save): Lisp function deleted.
18574 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18575 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18577 * xterm.h: Update prototype.
18579 2011-05-28 William Xu <william.xwl@gmail.com>
18581 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18582 exiting (Bug#8239).
18584 2011-05-28 Jim Meyering <meyering@redhat.com>
18586 Avoid a sign-extension bug in crypto_hash_function.
18587 * fns.c (to_uchar): Define.
18588 (crypto_hash_function): Use it to convert some newly-signed
18589 variables to unsigned, to avoid sign-extension bugs. For example,
18590 without this change, (md5 "truc") would evaluate to
18591 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18592 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18593 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18595 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18597 Integer overflow fixes.
18599 * dbusbind.c: Serial number integer overflow fixes.
18600 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18601 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18602 to hold a serial number that is too large for a fixnum.
18603 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18604 Check for serial numbers out of range. Decode any serial number
18605 that was so large that it became a float. (Bug#8722)
18607 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18608 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18609 Use XFASTINT rather than XUINT when numbers are nonnegative.
18610 (xd_append_arg, Fdbus_method_return_internal):
18611 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18612 arguments, check that Lisp number is nonnegative, rather than
18613 silently wrapping negative numbers around. (Bug#8722)
18614 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18617 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18619 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18621 ccl: Add integer overflow checks.
18622 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18623 (IN_INT_RANGE): New macros.
18624 (ccl_driver): Use them to check for integer overflow when
18625 decoding a CCL program. Many of the new checks are whether XINT (x)
18626 fits in int; it doesn't always, on 64-bit hosts. The new version
18627 doesn't catch all possible integer overflows, but it's an
18628 improvement. (Bug#8719)
18630 * alloc.c (make_event_array): Use XINT, not XUINT.
18631 There's no need for unsigned here.
18633 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18634 This follows up to the 2011-05-06 change that substituted uintptr_t
18635 for EMACS_INT. This case wasn't caught back then.
18637 Rework Fformat to avoid integer overflow issues.
18638 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18639 now (part of C89). Include <verify.h>.
18640 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18641 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18642 (Fformat): Avoid the prepass trying to compute sizes; it was only
18643 approximate and thus did not catch overflow reliably. Instead, walk
18644 through the format just once, formatting and computing sizes as we go,
18645 checking for integer overflow at every step, and allocating a larger
18646 buffer as needed. Keep track separately whether the format is
18647 multibyte. Keep only the most-recently calculated precision, rather
18648 than them all. Record whether each argument has been converted to
18649 string. Use EMACS_INT, not int, for byte and char and arg counts.
18650 Support field widths and precisions larger than INT_MAX. Avoid
18651 sprintf's undefined behavior with conversion specifications such as %#d
18652 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18653 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18654 formatting out-of-range floating point numbers with int
18655 formats. (Bug#8668)
18657 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18659 * data.c: Avoid integer truncation in expressions involving floats.
18660 * data.c: Include <intprops.h>.
18661 (arith_driver): When there's an integer overflow in an expression
18662 involving floating point, convert the integers to floating point
18663 so that the resulting value does not suffer from catastrophic
18664 integer truncation. For example, on a 64-bit host (* 4
18665 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18666 Do not rely on undefined behavior after integer overflow.
18668 merge count_size_as_multibyte, parse_str_to_multibyte
18669 * character.c, character.h (count_size_as_multibyte):
18670 Rename from parse_str_to_multibyte; all uses changed.
18671 Check for integer overflow.
18672 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18673 since it's now a duplicate of the other. This is more of
18674 a character than a buffer op, so better that it's in character.c.
18675 * fns.c, print.c: Adjust to above changes.
18677 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18679 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18681 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18683 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18684 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18685 (x_clipboard_manager_save): Now static.
18686 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18688 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18689 (crypto_hash_function): Now static.
18690 Fix pointer signedness problems. Avoid unnecessary initializations.
18692 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18694 * termhooks.h (Vselection_alist): Make it terminal-local.
18696 * terminal.c (create_terminal): Initialize it.
18698 * xselect.c: Support for clipboard managers.
18699 (Vselection_alist): Move to termhooks.h as terminal-local var.
18700 (LOCAL_SELECTION): New macro.
18701 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18702 (symbol_to_x_atom): Remove gratuitous arg.
18703 (x_handle_selection_request, lisp_data_to_selection_data)
18704 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18705 (x_own_selection, x_get_local_selection, x_convert_selection):
18706 New arg, specifying work frame. Use terminal-local Vselection_alist.
18707 (some_frame_on_display): Delete unused function.
18708 (Fx_own_selection_internal, Fx_get_selection_internal)
18709 (Fx_disown_selection_internal, Fx_selection_owner_p)
18710 (Fx_selection_exists_p): New optional frame arg.
18711 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18712 (x_handle_selection_clear): Don't treat other terminals with the
18713 same keyboard specially. Use the terminal-local Vselection_alist.
18714 (x_clear_frame_selections): Use Frun_hook_with_args.
18716 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18718 * xterm.h: Add support for those atoms.
18720 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18722 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18723 (converted_selections, conversion_fail_tag): New global variables.
18724 (x_selection_request_lisp_error): Free the above.
18725 (x_get_local_selection): Remove unnecessary code.
18726 (x_reply_selection_request): Args changed; handle arbitrary array
18727 of converted selections stored in converted_selections.
18728 Separate the XChangeProperty and SelectionNotify steps.
18729 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18730 (x_convert_selection): New function.
18731 (x_handle_selection_event): Simplify.
18732 (x_get_foreign_selection): Don't ignore incoming requests while
18733 waiting for an answer; this will fail when we implement
18734 SAVE_TARGETS, and seems unnecessary anyway.
18735 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18736 (Vx_sent_selection_functions): Doc fix.
18738 2011-05-26 Leo Liu <sdl.web@gmail.com>
18740 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18742 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18744 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18746 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18747 for fringe update if it has periodic bitmap.
18748 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18749 and fringe_bitmap_periodic_p.
18751 * fringe.c (get_fringe_bitmap_data): New function.
18752 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18753 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18754 row. Mark glyph row for fringe update if periodicity changed.
18756 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18757 for fringe update unless it has periodic bitmap.
18759 2011-05-25 Kenichi Handa <handa@m17n.org>
18761 * xdisp.c (get_next_display_element): Set correct it->face_id for
18762 a static composition.
18764 2011-05-24 Leo Liu <sdl.web@gmail.com>
18767 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18769 * fns.c (crypto_hash_function, Fsha1): New function.
18770 (Fmd5): Use crypto_hash_function.
18771 (syms_of_fns): Add Ssha1.
18773 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18775 * gnutls.c: Remove unused macros.
18776 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18777 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18778 Remove macros that are defined and never used.
18779 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18781 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18783 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18784 (Fx_get_selection_internal): Minor cleanup.
18785 (Fx_own_selection_internal): Rename arguments for consistency with
18788 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18790 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18792 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18794 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18796 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18798 * dispnew.c (scrolling_window): Don't exclude the case that the
18799 last enabled row in the desired matrix touches the bottom boundary.
18801 2011-05-21 Glenn Morris <rgm@gnu.org>
18803 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18804 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18805 and add some more files.
18807 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18809 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18810 report_file_error introduced by the change from 2011-05-07.
18812 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18814 * systime.h (Time): Define only if emacs is defined.
18815 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18816 where the include path doesn't have X11/X.h by default. See
18817 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18819 2011-05-20 Kenichi Handa <handa@m17n.org>
18821 * composite.c (find_automatic_composition): Fix previous change.
18823 2011-05-20 Glenn Morris <rgm@gnu.org>
18825 * lisp.mk: New file, split from Makefile.in.
18826 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18827 (shortlisp): Remove.
18828 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18830 2011-05-19 Glenn Morris <rgm@gnu.org>
18832 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18833 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18834 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18835 (lisp): Set the order to that of loadup.el.
18836 (shortlisp): Make it a copy of $lisp.
18837 (SOME_MACHINE_LISP): Remove.
18838 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18839 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18841 2011-05-18 Kenichi Handa <handa@m17n.org>
18843 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18844 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18845 (find_automatic_composition): Mostly rewrite for efficiency.
18847 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18849 * makefile.w32-in: Update dependencies.
18851 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18853 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18854 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18856 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18858 Fix some integer overflow issues, such as string length overflow.
18860 * insdel.c (count_size_as_multibyte): Check for string overflow.
18862 * character.c (lisp_string_width): Check for string overflow.
18863 Use EMACS_INT, not int, for string indexes and lengths; in
18864 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18865 the resulting string length overflows an EMACS_INT; instead,
18866 report a string overflow if no precision given. When checking for
18867 precision exhaustion, use a check that cannot possibly have
18868 integer overflow. (Bug#8675)
18869 * character.h (lisp_string_width): Adjust to new signature.
18871 * alloc.c (string_overflow): New function.
18872 (Fmake_string): Use it. This doesn't change behavior, but saves
18873 a few bytes and will simplify future changes.
18874 * character.c (string_escape_byte8): Likewise.
18875 * lisp.h (string_overflow): New decl.
18877 Fixups, following up to the user-interface timestamp change.
18878 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18879 for UI timestamps, instead of unsigned long.
18880 * msdos.c (mouse_get_pos): Likewise.
18881 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18882 * w32gui.h (Time): Define by including "systime.h" rather than by
18883 declaring it ourselves. (Bug#8664)
18885 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18886 * image.c (clear_image_cache): Likewise.
18888 * term.c (term_mouse_position): Don't assume time_t wraparound.
18890 Be more systematic about user-interface timestamps.
18891 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18892 and sometimes 'EMACS_UINT', to represent these timestamps.
18893 This change causes it to use 'Time' uniformly, as that's what X uses.
18894 This makes the code easier to follow, and makes it easier to catch
18895 integer overflow bugs such as Bug#8664.
18896 * frame.c (Fmouse_position, Fmouse_pixel_position):
18897 Use Time, not unsigned long, for user-interface timestamps.
18898 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18899 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18900 * keyboard.h (last_event_timestamp): Likewise.
18901 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18902 * menu.h (xmenu_show): Likewise.
18903 * term.c (term_mouse_position): Likewise.
18904 * termhooks.h (struct input_event.timestamp): Likewise.
18905 (struct terminal.mouse_position_hook): Likewise.
18906 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18907 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18908 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18909 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18910 what it was before.
18911 * menu.h, termhooks.h: Include "systime.h", for Time.
18913 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18914 Don't assume that the difference between two unsigned long values
18915 can fit into an integer. At this point, we know button_down_time
18916 <= event->timestamp, so the difference must be nonnegative, so
18917 there's no need to cast the result if double-click-time is
18918 nonnegative, as it should be; check that it's nonnegative, just in
18919 case. This bug is triggered when events are more than 2**31 ms
18920 apart (about 25 days). (Bug#8664)
18922 * xselect.c (last_event_timestamp): Remove duplicate decl.
18923 (x_own_selection): Remove needless cast to unsigned long.
18925 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18926 that always fit in int. Use a sentinel instead of a counter, to
18927 avoid a temp and to allay GCC's concerns about possible int overflow.
18928 * frame.h (struct frame): Use int for menu_bar_items_used
18929 instead of EMACS_INT, since it always fits in int.
18931 * menu.c (grow_menu_items): Check for int overflow.
18933 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18935 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18936 Before, the code was not consistent. These values cannot exceed
18937 2**31 - 1 so there's no need to make them unsigned.
18938 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18939 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18940 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18942 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18944 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18945 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18946 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18947 presumably because the widths might not match.
18949 * window.c (size_window): Avoid needless test at loop start.
18951 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18953 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18955 2011-05-12 Drew Adams <drew.adams@oracle.com>
18957 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18959 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18961 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18962 `width' to `bar_area_x' and `bar_area_width', respectively.
18963 (x_scroll_run): Take account of fringe background extension.
18965 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18966 Rename local vars `left' and `width' to `bar_area_x' and
18967 `bar_area_width', respectively.
18968 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18969 background extension.
18971 2011-05-10 Jim Meyering <meyering@redhat.com>
18973 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18975 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18977 * image.c (Finit_image_library): Return t for built-in image types,
18978 like pbm and xbm. (Bug#8640)
18980 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18982 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18984 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18986 * w32console.c (Fset_screen_color): Doc fix.
18987 (Fget_screen_color): New function.
18988 (syms_of_ntterm): Defsubr it.
18990 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18991 unlink the temporary file if Fcall_process didn't create it in the
18993 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18994 child process will be redirected to a file specified with `:file'.
18995 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18996 cue to call_process_cleanup not to close that handle.
18998 2011-05-07 Ben Key <bkey76@gmail.com>
19000 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19001 one of two shell specific rules, either bootstrap-temacs-CMD or
19002 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19003 to the previous implementation of the bootstrap-temacs rule.
19004 The bootstrap-temacs-CMD rule is similar to the previous
19005 implementation of the bootstrap-temacs rule except that it
19006 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19009 These changes, along with some changes to nt/configure.bat,
19010 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19011 earlier fix to add support for --cflags and --ldflags options
19012 that include quotes so that it works whether make uses cmd or
19015 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19017 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19018 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19020 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19021 a string. Handle both cases.
19022 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19023 (Fdbus_register_method): Use Qinvalid_function.
19025 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19027 * makefile.w32-in: Update dependencies.
19028 (LISP_H): Add inttypes.h and stdin.h.
19029 (PROCESS_H): Add unistd.h.
19031 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19033 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19034 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19036 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19038 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19040 * term.c (vfatal): Remove stray call to va_end.
19041 It's not needed and the C Standard doesn't allow it here anyway.
19043 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19044 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19046 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19049 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19051 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19053 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19055 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19057 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19059 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19060 * charset.c (Fdefine_charset_internal): Don't initialize
19061 charset.code_space[15]. The value was garbage, on hosts with
19062 32-bit int (Bug#8600).
19064 * lread.c (read_integer): Be more consistent with string-to-number.
19065 Use string_to_number to do the actual conversion; this avoids
19066 rounding errors and fixes some other screwups. Without this fix,
19067 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19068 (digit_to_number): Move earlier, for benefit of read_integer.
19069 Return -1 if the digit is out of range for the base, -2 if it is
19070 not a digit in any supported base. (Bug#8602)
19072 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19074 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19075 to match comment at start of function. This also removes a
19076 GCC warning about overflow in a 32+64-bit port.
19078 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19080 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19081 Reported by Stefan Monnier in
19082 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19083 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19084 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19086 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19087 (EMACS_UINTPTR): Likewise, with uintptr_t.
19089 * lisp.h: Prefer 64-bit EMACS_INT if available.
19090 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19091 on 32-bit hosts that have 64-bit int, so that they can access
19093 However, temporarily disable this change unless the temporary
19094 symbol WIDE_EMACS_INT is defined.
19096 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19098 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19099 This removes an assumption that EMACS_INT and long are the same
19100 width as pointers. The assumption is true for Emacs porting targets
19101 now, but we want to make other targets possible.
19102 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19103 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19104 In the rest of the code, change types of integers that hold casted
19105 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19106 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19107 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19108 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19109 No need to cast type when ORing.
19110 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19111 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19112 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19113 assume EMACS_INT is the same width as char *.
19114 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19115 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19116 Remove no-longer-needed casts.
19117 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19118 (xg_tool_bar_help_callback, xg_make_tool_item):
19119 Use EMACS_INTPTR to hold an integer
19120 that will be cast to void *; this can avoid a GCC warning
19121 if EMACS_INT is not the same width as void *.
19122 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19123 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19124 (current_message_1, set_message_1):
19125 Use a local to convert to proper width without a cast.
19126 * xmenu.c (dialog_selection_callback): Likewise.
19128 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19129 Also, don't assume VALBITS / RAND_BITS is less than 5,
19130 and don't rely on undefined behavior when shifting a 1 left into
19132 * lisp.h (get_random): Change signature to match.
19134 * lread.c (hash_string): Use size_t, not int, for hash computation.
19135 Normally we prefer signed values; but hashing is special, because
19136 it's better to use unsigned division on hash table sizes so that
19137 the remainder is nonnegative. Also, size_t is the natural width
19138 for hashing into memory. The previous code used 'int', which doesn't
19139 retain enough info to hash well into very large tables.
19140 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19142 * dbusbind.c: Don't possibly lose pointer info when converting.
19143 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19144 Use XPNTR rather than XHASH, so that the high-order bits of
19145 the pointer aren't lost when converting through void *.
19147 * eval.c (Fautoload): Don't double-shift a pointer.
19149 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

19232 * process.c: Include lisp.h before w32.h, not after.
19233 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19234 instead of gnutls_record_check_pending.
19236 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19238 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19240 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19241 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19244 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19246 * xterm.c (x_set_frame_alpha): Do not set property on anything

19251 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19253 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19255 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

19281 (Fcall_process_region): Ditto.
19283 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19285 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19286 rather than `XVECTOR (FOO)->size'.
19288 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19289 inttypes.h, as a gnulib replacement is used if it not available in
19292 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19294 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19295 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19296 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19298 * coding.c (coding_alloc_by_realloc): Error out if destination
19299 will grow beyond MOST_POSITIVE_FIXNUM.
19300 (decode_coding_emacs_mule): Abort if there isn't enough place in
19301 charbuf for the composition carryover bytes. Reserve an extra
19302 space for up to 2 characters produced in a loop.

19304 charbuf for the composition carryover bytes.
19306 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19308 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19309 aborting when %lld or %lll format is passed.
19310 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19311 %llo or %llx format is passed. (Bug#8545)
19313 * window.c (window_scroll_line_based): Use a marker instead of
19314 simple variables to record original value of point. (Bug#7952)
19316 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19317 produced by %s or %c overflows available buffer space. (Bug#8545)
19319 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19321 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

19331 (command_loop_1): Run `delayed-warnings-hook'
19332 if Vdelayed_warnings_list is non-nil.
19333 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19334 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19336 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19338 * doprnt.c (doprnt): Don't return value smaller than the buffer
19339 size if the message was truncated. (Bug#8545).
19341 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19343 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19344 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19346 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19348 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19350 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19352 * makefile.w32-in: Update dependencies.
19354 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19356 Improve `doprnt' and its usage. (Bug#8545)
19357 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19358 `format_end'. Remove support for %l as a conversion specifier.
19359 Don't use xrealloc. Improve diagnostics when the %l size modifier
19360 is used. Update the commentary.
19362 * eval.c (verror): Simplify calculation of size_t.
19364 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19367 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19369 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19372 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19374 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19375 This makes this file independent of the recent pseudovector change.
19377 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19379 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19381 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19382 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19383 Remove unused local.
19384 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19386 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19387 GCC 4.6.0 optimizes based on type-based alias analysis.
19388 For example, if b is of type struct buffer * and v of type struct
19389 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19390 != &v->size, and therefore "v->size = 1; b->size = 2; return
19391 v->size;" must therefore return 1. This assumption is incorrect
19392 for Emacs, since it type-puns struct Lisp_Vector * with many other
19393 types. To fix this problem, this patch adds a new type struct
19394 vectorlike_header that documents the constraints on layout of vectors
19395 and pseudovectors, and helps optimizing compilers not get fooled
19396 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19397 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19398 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19400 (XSETPVECTYPE): Rewrite in terms of new macro.
19401 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19402 This is a bit clearer, and further avoids the possibility of
19403 undesirable aliasing.
19404 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19405 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19406 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19407 since Lisp_Subr is a special case (no "next" field).
19408 (ASIZE): Now uses header.size rather than size.
19409 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19410 to avoid the hassle of writing XVECTOR (foo)->header.size.
19411 (struct vectorlike_header): New type.
19412 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19413 object, to help avoid aliasing.
19414 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19415 (SUBRP): Likewise, since Lisp_Subr is a special case.
19416 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19417 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19418 (struct Lisp_Hash_Table): Combine first two members into a single
19419 struct vectorlike_header member. All uses of "size" and "next" members
19420 changed to be "header.size" and "header.next".
19421 * buffer.h (struct buffer): Likewise.
19422 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19423 * frame.h (struct frame): Likewise.
19424 * process.h (struct Lisp_Process): Likewise.
19425 * termhooks.h (struct terminal): Likewise.
19426 * window.c (struct save_window_data, struct saved_window): Likewise.
19427 * window.h (struct window): Likewise.
19428 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19429 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19430 * buffer.c (init_buffer_once): Likewise.
19431 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19433 * process.c (Fformat_network_address): Use local var for size,
19436 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19438 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19439 * data.c (atof): Remove decl; no longer used or needed.
19440 (digit_to_number): Move to lread.c.
19441 (Fstring_to_number): Use new string_to_number function, to be
19442 consistent with how the Lisp reader treats infinities and NaNs.
19443 Do not assume that floating-point numbers represent EMACS_INT
19444 without losing information; this is not true on most 64-bit hosts.
19445 Avoid double-rounding errors, by insisting on integers when
19446 parsing non-base-10 numbers, as the documentation specifies.
19447 * lisp.h (string_to_number): New decl, replacing ...
19448 (isfloat_string): Remove.
19449 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19450 (read1): Do not accept +. and -. as integers; this
19451 appears to have been a coding error. Similarly, do not accept
19452 strings like +-1e0 as floating point numbers. Do not report
19453 overflow for integer overflows unless the base is not 10 which
19454 means we have no simple and reliable way to continue.
19455 Break out the floating-point parsing into a new
19456 function string_to_number, so that Fstring_to_number parses
19457 floating point numbers consistently with the Lisp reader.
19458 (digit_to_number): Move here from data.c. Make it static inline.
19459 (E_CHAR, EXP_INT): Remove, replacing with ...
19460 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19461 (string_to_number): New function, replacing isfloat_string.
19462 This function checks for valid syntax and produces the resulting
19463 Lisp float number too. Rework it so that string-to-number
19464 no longer mishandles examples like "1.0e+". Use strtoumax,
19465 so that overflow for non-base-10 numbers is reported only when
19466 there's no portable and simple way to convert to floating point.
19468 * textprop.c (set_text_properties_1): Rewrite for clarity,
19469 and to avoid GCC warning about integer overflow.
19471 * intervals.h (struct interval): Use EMACS_INT for members
19472 where EMACS_UINT might cause problems. See
19473 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19474 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19475 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19477 (offset_intervals): Tell GCC not to worry about length overflow
19478 when negating a negative length.
19480 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19481 (overrun_check_free): Likewise.
19483 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19484 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19487 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19488 (gnutls_make_error): Rename local to avoid shadowing.
19489 (gnutls_emacs_global_deinit): ifdef out; not used.
19490 (Fgnutls_boot): Use const for pointer to readonly storage.
19491 Comment out unused local. Fix pointer signedness problems.
19493 * lread.c (openp): Don't stuff size_t into an 'int'.
19494 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19495 about possible signed overflow.
19497 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19498 (GDK_KEY_g): Don't define if already defined.
19499 (xg_prepare_tooltip): Avoid pointer signedness problem.
19500 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19502 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19503 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19505 * xfns.c (Fx_window_property): Simplify a bit,
19506 to make a bit faster and to avoid GCC 4.6.0 warning.
19507 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19509 * fns.c (internal_equal): Don't assume size_t fits in int.
19511 * alloc.c (compact_small_strings): Tighten assertion a little.
19513 Replace pEd with more-general pI, and fix some printf arg casts.
19514 * lisp.h (pI): New macro, generalizing old pEd macro to other
19515 conversion specifiers. For example, use "...%"pI"d..." rather
19516 than "...%"pEd"...".
19517 (pEd): Remove. All uses replaced with similar uses of pI.
19518 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19519 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19520 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19521 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19522 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19523 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19524 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19526 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19527 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19528 * print.c (safe_debug_print, print_object): Likewise.
19529 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19531 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19532 avoiding the 0 flag, which is not portable.
19533 * process.c (Fmake_network_process): Use pI to avoid cast.
19534 * region-cache.c (pp_cache): Likewise.
19535 * xdisp.c (decode_mode_spec): Likewise.
19536 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined

19540 (x_get_window_property): Don't truncate byte count to an 'int'
19543 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19544 here, since it parses constructs like leading '-' and spaces,
19545 which are not wanted; and it overflows with large numbers.
19546 Instead, simply match F[0-9]+, which is what is wanted anyway.
19548 * alloc.c: Remove unportable assumptions about struct layout.
19549 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19550 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19551 (allocate_vectorlike, make_pure_vector): Use the new macros,
19552 plus offsetof, to remove unportable assumptions about struct layout.
19553 These assumptions hold on all porting targets that I know of, but
19554 they are not guaranteed, they're easy to remove, and removing them
19555 makes further changes easier.
19557 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19558 This doesn't fix a bug but makes the code clearer.
19559 (string_overrun_cookie): Now const. Use initializers that
19560 don't formally overflow signed char, to avoid warnings.
19561 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19562 can cause Emacs to crash when string overrun checking is enabled.
19563 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19564 multiple of sizeof (EMACS_INT); it need not be, if
19565 alignof(EMACS_INT) < sizeof (EMACS_INT).
19566 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

19597 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19598 "cast to pointer from integer of different size".
19600 Improve doprnt and its use in verror. (Bug#8545)
19601 * doprnt.c (doprnt): Document the set of format control sequences
19602 supported by the function. Use SAFE_ALLOCA instead of always
19605 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19606 is one byte too soon. Don't use xrealloc; instead xfree and

19618 docstring. Start callback support.
19619 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19620 unless a fatal error occurred. Call gnutls_alert_send_appropriate

19724 codepoint of an invalid character, to avoid displaying a bogus
19727 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19728 `error', not SYMBOL_NAME itself.
19730 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

19733 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19734 to `error' in error message about FINAL_CHAR argument. Make sure
19735 FINAL_CHAR is a character, and use %c when it is passed as
19736 argument to `error'.
19738 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19740 * s/ms-w32.h (localtime): Redirect to sys_localtime.
19742 * w32.c: Include <time.h>.

19806 * dispextern.h (struct redisplay_interface): Rename param
19807 to avoid shadowing.
19808 * termhooks.h (struct terminal): Likewise.

19925 * nsfont.m: Fixed bugs in ns_get_family and
19926 ns_descriptor_to_entity that were caused by using free to
19927 deallocate memory blocks that were allocated by xmalloc (via
19928 xstrdup). This caused Emacs to crash when compiled with
19929 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19930 --enable-checking=xmallocoverrun). xfree is now used to
19931 deallocate these memory blocks.

19945 (emacs_read, emacs_write): Remove check for negative size, as the
19946 Emacs source code has been audited now.
19947 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
19948 (emacs_read, emacs_write): Use it.
19949 * process.c (send_process): Adjust to the new signatures of
19950 emacs_write and emacs_gnutls_write. Do not attempt to store
19951 a byte offset into an 'int'; it might overflow.
19952 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

20404 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20406 * charset.c (Fclear_charset_maps): Use xfree instead of free.
20408 * keyboard.c (parse_tool_bar_item): Likewise.
20409 * sound.c (sound_cleanup, alsa_close): Likewise.
20410 * termcap.c (tgetent): Likewise.
20411 * xfns.c (x_default_font_parameter): Likewise.
20412 * xsettings.c (read_and_apply_settings): Likewise.
20414 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20415 (overrun_check_free): Protoize.
20417 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20419 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20420 since callers should never pass a negative size.
20421 Change the signature to match that of plain 'read' and 'write'; see
20422 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20423 * lisp.h: Update prototypes of emacs_write and emacs_read.
20425 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20427 * xdisp.c (redisplay_window): Don't try to determine the character
20428 position of the scroll margin if the window start point w->startp
20429 is outside the buffer's accessible region. (Bug#8468)
20431 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20433 Fix write-region and its subroutines for buffers > 2GB.
20434 * fileio.c (a_write, e_write): Modify declaration of arguments and
20435 local variables to support buffers larger than 2GB.
20436 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20438 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20439 argument, local variables, and return value.
20441 * lisp.h: Update prototypes of emacs_write and emacs_read.
20443 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20445 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20447 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20449 Fix more problems found by GCC 4.6.0's static checks.
20451 * xdisp.c (vmessage): Use a better test for character truncation.
20453 * charset.c (load_charset_map): <, not <=, for optimization,
20454 and to avoid potential problems with integer overflow.
20455 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20456 * casetab.c (set_identity, shuffle): Likewise.
20457 * editfns.c (Fformat): Likewise.
20458 * syntax.c (skip_chars): Likewise.
20460 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20461 This also lets GCC 4.6.0 generate slightly better loop code.
20463 * callint.c (Fcall_interactively): <, not <=, for optimization.
20464 (Fcall_interactively): Count the number of arguments produced,
20465 not the number of arguments given. This is simpler and lets GCC
20466 4.6.0 generate slightly better code.
20468 * ftfont.c: Distingish more carefully between FcChar8 and char.
20469 The previous code passed unsigned char * to a functions like
20470 strlen and xstrcasecmp that expect char *, which does not
20471 conform to the C standard.
20472 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20473 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20474 char * when the C standard requires it.
20476 * keyboard.c (read_char): Remove unused var.
20478 * eval.c: Port to Windows vsnprintf (Bug#8435).
20479 Include <limits.h>.
20480 (SIZE_MAX): Define if the headers do not.
20481 (verror): Do not give up if vsnprintf returns a negative count.
20482 Instead, grow the buffer. This ports to Windows vsnprintf, which
20483 does not conform to C99. Problem reported by Eli Zaretskii.
20484 Also, simplify the allocation scheme, by avoiding the need for
20485 calling realloc, and removing the ALLOCATED variable.
20487 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20489 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20490 But keep the doprint source code for now, as we might revamp it
20491 and use it again (Bug#8435).
20492 * lisp.h (doprnt): Remove.
20493 * Makefile.in (base_obj): Remove doprnt.o.
20494 * deps.mk (doprnt.o): Remove.
20496 error: Print 32- and 64-bit integers portably (Bug#8435).
20497 Without this change, on typical 64-bit hosts error ("...%d...", N)
20498 was used to print both 32- and 64-bit integers N, which relied on
20499 undefined behavior.
20500 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20501 * lisp.h (error, verror): Mark as printf-like functions.
20502 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20503 Report overflow in size calculations when allocating printf buffer.
20504 Do not truncate output string at its first null byte.
20505 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20506 Truncate the output at a character boundary, since vsnprintf does not
20508 * charset.c (check_iso_charset_parameter): Convert internal
20509 character to string before calling 'error', since %c now has the
20511 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20512 overflow when computing char to be passed to 'error'. Do not
20513 pass Lisp_Object to 'error'; pass the integer instead.
20514 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20515 formatted with plain %d.
20517 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20519 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20521 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20523 * xterm.c (x_catch_errors): Remove duplicate declaration.
20525 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20527 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20529 2011-04-10 Jim Meyering <meyering@redhat.com>
20531 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20532 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20533 return ssize_t not "int", and use size_t as the buffer length.
20534 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20535 * gnutls.h: Update declarations.
20536 * process.c (read_process_output): Use ssize_t, to match.
20537 (send_process): Likewise.
20539 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20541 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20543 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20545 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20546 Use unsigned char, to match FcChar8 type definition.
20548 * xterm.c (handle_one_xevent):
20549 * xmenu.c (create_and_show_popup_menu):
20550 * xselect.c (x_decline_selection_request)
20551 (x_reply_selection_request): Avoid type-punned deref of X events.
20553 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20555 Fix some uses of `int' instead of EMACS_INT.
20556 * search.c (string_match_1, fast_string_match)
20557 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20558 (scan_buffer, find_next_newline_no_quit)
20559 (find_before_next_newline, search_command, Freplace_match)
20560 (Fmatch_data): Make some `int' variables be EMACS_INT.
20562 * xdisp.c (display_count_lines): 3rd argument and return value now
20563 EMACS_INT. All callers changed.
20564 (pint2hrstr): Last argument is now EMACS_INT.
20566 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20567 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20568 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20569 (decode_coding_utf_16, decode_coding_emacs_mule)

20571 (decode_coding_ccl, decode_coding_charset)
20572 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20573 (decode_coding_iso_2022, decode_coding_emacs_mule)
20574 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20575 <char_offset, last_offset>: Declare EMACS_INT.
20576 (encode_coding_utf_8, encode_coding_utf_16)
20577 (encode_coding_emacs_mule, encode_invocation_designation)
20578 (encode_designation_at_bol, encode_coding_iso_2022)
20579 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20580 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20582 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20583 (encode_invocation_designation): Last argument P_NCHARS is now
20585 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20586 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20588 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20591 * ccl.c (Fccl_execute_on_string): Declare some variables
20594 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20596 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20598 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20600 * process.c (Fformat_network_address): Doc fix.
20602 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20604 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20606 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20608 * keyboard.c (read_char): Call Lisp function help-form-show,
20609 instead of using internal_with_output_to_temp_buffer.
20610 (Qhelp_form_show): New var.
20611 (syms_of_keyboard): Use DEFSYM macro.
20613 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20615 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20617 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20619 * process.c (Flist_processes): Remove to Lisp.
20620 (list_processes_1): Delete.

20624 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20626 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20628 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20630 Fix more problems found by GCC 4.6.0's static checks.
20632 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20634 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20636 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20638 * xdisp.c (vmessage): Mark as a printf-like function.
20640 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20642 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20644 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20645 printf-like functions.
20646 (tiff_load): Add casts to remove these marks before passing them
20647 to system-supplied API.
20649 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20651 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20652 This avoids several warnings with gcc -Wstrict-overflow.
20653 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20654 directly, rather than having caller test rule sign. This avoids
20655 some unnecessary tests.
20656 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20657 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20658 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20660 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20661 (xfont_open): Avoid unnecessary tests.
20663 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20665 * composite.h, composite.c (composition_gstring_put_cache):
20666 Use EMACS_INT, not int, for length.

20669 breaking out part of COMPOSITION_DECODE_RULE.
20670 (COMPOSITION_DECODE_RULE): Use it.
20671 * composite.c (get_composition_id): Remove unused local vars,
20672 by using the new macro.
20674 * textprop.c (set_text_properties_1): Change while to do-while,
20675 since the condition is always true at first.
20677 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20678 (interval_deletion_adjustment): Return unsigned value.
20681 * process.c (list_processes_1, create_pty, read_process_output):
20682 (exec_sentinel): Remove vars that were set but not used.
20683 (create_pty): Remove unnecessary "volatile"s.

20691 (update_syntax_table): Use unsigned instead of int.
20693 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20694 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20695 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20697 * print.c (print_error_message): Avoid int overflow.
20699 * font.c (font_list_entities): Redo for clarity,
20700 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20702 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20703 (font_score): Avoid potential overflow in diff calculation.
20705 * fns.c (substring_both): Remove var that is set but not used.
20706 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20708 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20710 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20711 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20712 can always succeed if overflow has undefined behavior.
20714 * search.c (boyer_moore, wordify): Remove vars set but not used.
20715 (wordify): Omit three unnecessary tests.
20717 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20718 All callers changed. This avoids the need for an unused var.
20720 * casefiddle.c (casify_region): Remove var that is set but not used.
20722 * dired.c (file_name_completion): Remove var that is set but not used.
20724 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20726 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20727 (Finsert_file_contents): Remove unnecessary code checking fd.
20729 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20730 Check for integer overflow on size calculations.
20732 * buffer.c (Fprevious_overlay_change): Remove var that is set
20735 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20736 Remove vars that are set but not used.
20737 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20738 (timer_check_2): Mark vars as initialized.
20740 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20742 * image.c (lookup_image): Remove var that is set but not used.
20743 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20745 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20746 that are set but not used.
20748 * xfns.c (make_invisible_cursor): Don't return garbage
20749 if XCreateBitmapFromData fails (Bug#8410).
20751 * xselect.c (x_get_local_selection, x_handle_property_notify):
20752 Remove vars that are set but not used.
20754 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

20764 (map_tty_color) [!defined MSDOS]: Likewise.
20766 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20768 * coding.c: Remove vars that are set but not used.
20769 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20770 All callers changed.
20771 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20772 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20773 (decode_coding_charset): Remove vars that are set but not used.
20775 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20776 that is set but not used.
20778 * print.c (print_object): Remove var that is set but not used.
20780 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20781 The gnulib version avoids calling malloc in the usual case,
20782 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20783 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20784 * filelock.c (current_lock_owner): Likewise.
20785 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20786 * sysdep.c: Include allocator.h, careadlinkat.h.
20787 (emacs_no_realloc_allocator): New static constant.
20788 (emacs_readlink): New function.
20789 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20790 ../lib/careadlinkat.h.
20792 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20794 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20795 first non-nil return value).
20797 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20799 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20800 if not defined (Bug#8403).

20804 * xdisp.c (display_count_lines): Remove parameter `start',
20805 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

20809 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20810 and thereabouts. All callers changed.
20811 (get_per_char_metric): Remove parameter `f', unused since
20812 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20816 do not dereference NULL upon failed strdup
20817 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20818 (ns_get_family): Likewise.
20820 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20822 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.

20860 (Feval): New `lexical' arg.
20861 (eval_sub): New function extracted from Feval. Use it almost
20862 everywhere where Feval was used. Look up vars in lexical env.
20864 (Ffunctionp): Move from subr.el.
20865 (Ffuncall): Handle closures.
20866 (apply_lambda): Remove `eval_flags'.
20867 (funcall_lambda): Handle closures and new byte-code-functions.
20868 (Fspecial_variable_p): New function.
20869 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20870 but without exporting it to Lisp.
20872 * doc.c (Fdocumentation, store_function_docstring):
20873 * data.c (Finteractive_form): Handle closures.
20875 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20878 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20880 (exec_byte_code): New function extracted from Fbyte_code to handle new
20881 calling convention for byte-code-functions. Add new byte-codes.
20883 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20885 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20887 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20889 * xdisp.c (redisplay_internal): Fix prototype.
20891 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20893 * xdisp.c (SCROLL_LIMIT): New macro.
20894 (try_scrolling): Use it when setting scroll_limit.
20895 Limit scrolling to 100 screen lines.
20896 (redisplay_window): Even when falling back on "recentering",
20897 position point in the window according to scroll-conservatively,
20898 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20900 (try_scrolling): When point is above the window, allow searching
20901 as far as scroll_max, or one screenful, to compute vertical
20902 distance from PT to the scroll margin position. This prevents
20903 try_scrolling from unnecessarily failing when
20904 scroll-conservatively is set to a value slightly larger than the
20905 window height. Clean up the case of PT below the margin at bottom
20906 of window: scroll_max can no longer be INT_MAX. When aggressive
20907 scrolling is in use, don't let point enter the opposite scroll
20908 margin as result of the scroll.
20909 (syms_of_xdisp) <scroll-conservatively>: Document the
20910 threshold of 100 lines for never-recentering scrolling.
20912 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20914 * dispextern.h (move_it_by_lines):
20915 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20916 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20917 (message_log_check_duplicate): Remove parameters `prev_bol' and
20918 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20919 (redisplay_internal): Remove parameter `preserve_echo_area',
20920 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20922 * indent.c (Fvertical_motion):
20923 * window.c (window_scroll_pixel_based, Frecenter):
20924 Don't pass `need_y_p' to `move_it_by_lines'.
20926 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20928 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20929 steal a few bits to be more compact.
20930 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20931 Remove unneeded casts.
20933 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20935 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20937 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20938 binding" message (bug#7967).
20940 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20942 Fix more problems found by GCC 4.6.0's static checks.
20944 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20945 Remove unused local var.
20947 * editfns.c (Fmessage_box): Remove unused local var.
20949 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20950 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20951 Omit unused local vars.
20952 * window.c (shrink_windows): Omit unused local var.
20953 * menu.c (digest_single_submenu): Omit unused local var.
20954 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20955 Omit unused local var.
20957 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20958 Don't assume string length fits in int.
20959 (keyremap_step, read_key_sequence): Use size_t for sizes.
20960 (read_key_sequence): Don't check last_real_key_start redundantly.
20962 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20963 instead of alloca (Bug#8344).
20965 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20966 (Fbacktrace_frame): Don't assume nframes fits in int.
20968 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20970 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20973 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20975 * cm.c (calccost): Turn while-do into do-while, for clarity.
20977 * keyboard.c (syms_of_keyboard): Use the same style as later
20978 in this function when indexing through an array. This also
20979 works around GCC bug 48267.
20981 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20983 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20985 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20986 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20988 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20989 This avoids undefined behavior on integer overflow, and is a bit
20990 more convenient anyway since it is compared to a size_t variable.
20992 Variadic C functions now count arguments with size_t, not int.
20993 This avoids an unnecessary limitation on 64-bit machines, which
20994 caused (substring ...) to crash on large vectors (Bug#8344).
20995 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20996 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20997 All variadic functions and their callers changed accordingly.
20998 (struct gcpro.nvars): Now size_t, not int. All uses changed.
20999 * data.c (arith_driver, float_arith_driver): Likewise.
21000 * editfns.c (general_insert_function): Likewise.
21001 * eval.c (struct backtrace.nargs, interactive_p)
21002 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21003 (funcall_lambda, mark_backtrace): Likewise.
21004 * fns.c (concat): Likewise.
21005 * frame.c (x_set_frame_parameters): Likewise.
21006 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21007 0 if not found, not -1. All callers changed.
21009 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21010 (stack_copy_size): Now size_t, not int.
21011 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21013 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21015 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21016 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21017 All callers changed.
21019 * lisp.h (multibyte_char_to_unibyte):
21020 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21021 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21022 * character.h (CHAR_TO_BYTE8):
21023 * cmds.c (internal_self_insert):
21024 * editfns.c (general_insert_function):
21025 * keymap.c (push_key_description):
21026 * search.c (Freplace_match):
21027 * xdisp.c (message_dolog, set_message_1): All callers changed.
21029 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21031 * keyboard.c (safe_run_hook_funcall): New function.
21032 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21033 don't set the hook to nil, but remove the offending function instead.
21034 (Qcommand_hook_internal): Remove, unused.
21035 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21036 Vcommand_hook_internal.
21038 * eval.c (enum run_hooks_condition): Remove.
21039 (funcall_nil, funcall_not): New functions.
21040 (run_hook_with_args): Call each function through a `funcall' argument.
21041 Remove `cond' argument, now redundant.
21042 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21043 (Frun_hook_with_args_until_failure): Adjust accordingly.
21044 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21046 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21048 * dispextern.h (string_buffer_position): Remove declaration.
21050 * print.c (strout): Remove parameter `multibyte', unused since
21051 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21053 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21054 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21055 All callers changed.
21057 * w32.c (_wsa_errlist): Use braces for struct initializers.
21059 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21060 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21061 All callers changed.
21062 (string_buffer_position): Likewise. Also, make static (it's never
21063 used outside xdisp.c).
21064 (cursor_row_p): Remove parameter `w', unused since
21065 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21067 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21068 All callers changed.
21070 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21072 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21077 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
21078 (ns_update_auto_hide_menu_bar): New functions.
21079 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

21083 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21085 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21087 * nsmenu.m (runDialogAt): Remove argument to timer_check.
21089 2011-03-27 Glenn Morris <rgm@gnu.org>
21091 * syssignal.h: Replace RETSIGTYPE with void.
21092 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
21093 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
21094 Replace SIGTYPE with void everywhere.
21095 * s/usg5-4-common.h (SIGTYPE): Remove definition.
21096 * s/template.h (SIGTYPE): Remove commented out definition.
21098 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21100 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21101 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21103 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21105 * w32.c (read_unc_volume): Use parameter `henum', instead of
21106 global variable `wget_enum_handle'.
21108 * keymap.c (describe_vector): Remove parameters `indices' and
21109 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21112 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
21114 * keyboard.c (timer_check): Remove parameter `do_it_now',
21115 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
21116 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
21117 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
21119 * keyboard.c (read_char):
21120 * w32menu.c (w32_menu_display_help):
21121 * xmenu.c (show_help_event, menu_help_callback):
21122 Adjust calls to `show_help_echo'.
21124 * gtkutil.c (xg_maybe_add_timer):
21125 * keyboard.c (readable_events):
21126 * process.c (wait_reading_process_output):
21127 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21129 * insdel.c (adjust_markers_gap_motion):
21130 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
21131 (gap_left, gap_right): Don't call it.
21133 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
21135 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
21136 incurred during fontification.

21177 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
21179 * w32term.c (x_set_glyph_string_clipping):
21180 Don't pass uninitialized region to CombineRgn.
21182 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
21184 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
21185 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
21186 (Fx_close_connection): Remove unused variable `i'.
21188 * w32font.c (w32font_draw): Return number of glyphs.
21189 (w32font_open_internal): Remove unused variable `i'.

21202 (uniscribe_font_driver): Add missing initializers.
21204 2011-03-23 Julien Danjou <julien@danjou.info>
21206 * term.c (Fsuspend_tty, Fresume_tty):
21207 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21208 * window.c (temp_output_buffer_show):
21209 * insdel.c (signal_before_change):
21210 * frame.c (Fhandle_switch_frame):
21211 * fileio.c (Fdo_auto_save):
21212 * emacs.c (Fkill_emacs):
21213 * editfns.c (save_excursion_restore):
21214 * cmds.c (internal_self_insert):
21215 * callint.c (Fcall_interactively):
21216 * buffer.c (Fkill_all_local_variables):
21217 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21219 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21220 unconditionally since it does the check itself.
21222 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21224 Fix more problems found by GCC 4.5.2's static checks.
21226 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21227 the first time through the loop, since we know p0 < p1 then.
21228 This also avoids a gcc -Wstrict-overflow warning.
21230 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21231 leading to a memory leak, possible in functions like
21232 load_charset_map_from_file that can allocate an unbounded number
21233 of objects (Bug#8318).
21235 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21236 that could (at least in theory) be that large.
21238 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21239 This is less likely to overflow, and avoids undefined behavior if
21240 overflow does occur. All callers changed. Use strtoul to scan
21241 for the unsigned long integer.
21242 (pint2hrstr): Simplify and tune code slightly.
21243 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21245 * scroll.c (do_scrolling): Work around GCC bug 48228.
21246 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
21248 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
21249 This also avoids a warning with gcc -Wstrict-overflow.
21250 (validate_x_resource_name): Simplify count usage.
21251 This also avoids a warning with gcc -Wstrict-overflow.
21253 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21256 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21258 * process.c (Fmake_network_process): Use socklen_t, not int,
21259 where POSIX says socklen_t is required in portable programs.
21260 This fixes a porting bug on hosts like 64-bit HP-UX, where
21261 socklen_t is wider than int (Bug#8277).
21262 (Fmake_network_process, server_accept_connection):
21263 (wait_reading_process_output, read_process_output):
21266 * process.c: Rename or move locals to avoid shadowing.
21267 (list_processes_1, Fmake_network_process):
21268 (read_process_output_error_handler, exec_sentinel_error_handler):
21269 Rename or move locals.
21270 (Fmake_network_process): Define label "retry_connect" only if needed.
21271 (Fnetwork_interface_info): Fix pointer signedness.
21272 (process_send_signal): Add cast to avoid pointer signedness problem.
21273 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21274 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21276 Make tparam.h and terminfo.c consistent.
21277 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21278 Include tparam.h instead, since it declares them.
21279 * cm.h (PC): Remove extern decl; tparam.h now does this.
21280 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21281 * terminfo.c: Include tparam.h, to check interfaces.
21282 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21283 (tparam): Adjust signature to match interface in tparam.h;
21284 this removes some undefined behavior. Check that outstring and len
21285 are zero, which they always are with Emacs.
21286 * tparam.h (PC, BC, UP): New extern decls.
21288 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21289 (xftfont_open): Rename locals to avoid shadowing.
21291 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21292 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

21340 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21342 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21343 This should get cleaned up, so that child_setup has the
21344 same signature on all platforms.

21508 (Fmemory_limit): Cast sbrk's returned value to char *.
21510 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21518 to use the following functions instead of these macros.
21519 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21520 EMACS_INT, since callers assume the returned value fits in int.
21521 (upcase1): Likewise, for UPCASE_TABLE.
21522 (uppercasep, lowercasep, upcase): New static inline functions.
21523 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21533 (regex_compile, re_match_2_internal): Mark locals as initialized.
21534 (RETALLOC_IF): Define only if needed.
21535 (WORDCHAR_P): Likewise. This one is never needed, but is used
21536 only in a comment talking about a compiler bug, so put inside
21537 the #if 0 of that comment.
21538 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21539 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21566 New macros, so that the caller can use some names other than
21567 gcpro1, gcpro2, etc.
21568 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21570 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21571 argument, for consistency with GCPRO2_VAR, etc: it is now the
21572 prefix of the variable, not the variable itself. All uses
21574 * dired.c (directory_files_internal, file_name_completion):
21575 Rename locals to avoid shadowing.
21577 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21578 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21579 dired.c's scmp function, had undefined behavior.
21580 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21581 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21582 * buffer.h: ... to here, because these macros use current_buffer,
21583 and the new implementation with inline functions needs to have
21584 current_buffer in scope now, rather than later when the macros
21586 (downcase, upcase1): New static inline functions.
21587 (DOWNCASE, UPCASE1): Reimplement using these functions.
21588 This avoids undefined behavior in expressions like
21589 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21590 from race conditions in accessing the global variables
21591 case_temp1 and case_temp2.
21592 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21593 * lisp.h (case_temp1, case_temp2): Remove their decls.
21594 * character.h (ASCII_CHAR_P): Move from here ...
21595 * lisp.h: ... to here, so that the inline functions mentioned
21596 above can use them.
21598 * dired.c (directory_files_internal_unwind): Now static.
21600 * fileio.c (file_name_as_directory, directory_file_name):

21603 (file_name_as_directory): Use const pointers when appropriate.
21604 (Fexpand_file_name): Likewise. In particular, newdir might
21605 point at constant storage, so make it a const pointer.
21606 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21607 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21609 (Fset_file_times, Finsert_file_contents, auto_save_error):

21614 to avoid shadowing.
21616 * marker.c (bytepos_to_charpos): Remove; unused.
21618 * lisp.h (verify_bytepos, count_markers): New decls,
21619 so that gcc does not warn that these functions aren't declared.
21621 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21622 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21623 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21624 (copy_text): Remove unused local var.

21629 * buffer.c (fix_overlays_before): Mark locals as initialized.
21630 (fix_start_end_in_overlays): Likewise. This function should be
21631 simplified by using pointers-to-pointers, but that's a different
21633 (switch_to_buffer_1): Now static.
21634 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21635 (report_overlay_modification): Rename locals to avoid shadowing.

21638 Fix pointer signedness issue.
21639 (sys_subshell): Mark local as volatile if checking for lint,
21640 to suppress a gcc -Wclobbered warning that does not seem to be right.
21641 (MAXPATHLEN): Define only if needed.
21643 * process.c (serial_open, serial_configure): Move decls from here ...
21644 * systty.h: ... to here, so that they can be checked.
21646 * fns.c (get_random, seed_random): Move extern decls from here ...
21647 * lisp.h: ... to here, so that they can be checked.
21649 * sysdep.c (reset_io): Now static.

21658 (describe_map_tree):
21659 Rename locals to avoid shadowing.
21661 * keyboard.c: Declare functions static if they are not used elsewhere.
