3 * marker.c (set_marker_internal): If desired position is passed
4 as a marker, avoid call to buf_charpos_to_bytepos.
5 * window.c (Fset_window_point): Omit redundant type checking.
6 (Fset_window_start): Likewise. Format comment.
7 (window_scroll_pixel_based): Use set_marker_restricted_both
8 with character and byte positions obtained from an iterator.
9 (Fset_window_configuration): Use set_marker_restricted_both.
10 * xdisp.c (message_dolog): Likewise.
12 2013-02-10 Eli Zaretskii <eliz@gnu.org>
14 * xdisp.c (move_it_vertically_backward, move_it_by_lines): When
15 text lines are longer than window's screen lines, don't move back
16 too far. This speeds up some redisplay operations. (Bug#13675)

23 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
25 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
28 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
30 Minor hashing refactoring.
31 * fns.c (SXHASH_REDUCE): Move to lisp.h.
32 (sxhash_float): Return EMACS_UINT, for consistency with the other
34 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
35 non-static inline function and therefore can't use static vars.
36 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
37 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
38 with the other hash functions.
40 2013-02-09 Eli Zaretskii <eliz@gnu.org>
42 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
43 XXXXXX part of the temporary file pattern is not downcased even
44 when w32-downcase-file-names is non-nil. (Bug#13661)
46 * xdisp.c (decode_mode_spec): Remove handling of %t.

60 (search_command): Use eassert.
61 * syntax.c (struct lisp_parse_state): New member location_byte.
62 (scan_sexps_forward): Record from_byte and avoid redundant
63 character to byte position calculation ...

68 * lisp.h (make_uninit_vector): New function.
69 * alloc.c (Fvector, Fmake_byte_code):
70 * ccl.c (Fregister_ccl_program):

87 * coding.c (Fdefine_coding_system_internal): Use AREF where
88 argument is known to be a vector.
89 * fns.c (Flocale_info): Likewise for ASET.
90 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
91 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
93 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
95 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar

100 updateCollectionBehaviour.
102 * nsterm.m (NEW_STYLE_FS): Remove.
103 (ns_last_use_native_fullscreen): New variable.
104 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.

106 if isFullscreen returns YES.
107 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
108 (check_native_fs): New function.
109 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
110 (ns_term_init): Remove NEW_STYLE_FS.

121 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
122 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
123 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.

126 (syms_of_nsterm): Add ns-use-native-fullscreen.
128 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
130 * fileio.c (Qchoose_write_coding_system): Now static.
132 2013-02-04 Eli Zaretskii <eliz@gnu.org>
134 * xdisp.c (window_buffer_changed): region_showing can be negative,
135 which still means region is being displayed.
136 (redisplay_internal): Resurrect code that forced redisplay of the
137 whole window when showing region and the mark has changed. Record
138 the new mark position to allow redisplay optimizations.
139 (display_line): If it->region_beg_charpos is non-zero, set the
140 window's region_showing member to -1. (Bug#13623) (Bug#13626)
142 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
143 not bitfield of 1 bit.
145 2013-02-03 Daniel Colascione <dancol@dancol.org>
147 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
148 daemon mode works on cygw32 when Emacs is installed and not just
151 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
153 Avoid file time stamp bug on MS-Windows (Bug#13149).
154 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
155 as FAT32 doesn't update time stamps when truncating them.
156 Also, check that a file time stamp is not a multiple of 100 ns;
157 this should catch all instances of the problem on MS-Windows,
158 as its native file system resolution is 100 ns or worse, and
159 checking for a non-multiple of 100 ns should impose only a small
160 overhead on systems with ns resolution.
162 2013-02-02 Eli Zaretskii <eliz@gnu.org>
164 Avoid encoding file names on MS-Windows when they need to be run
165 through dostounix_filename.
166 * w32.c (normalize_filename): Accept an additional argument
167 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
168 downcase it even if w32-downcase-file-names is non-nil.
169 (dostounix_filename): Accept an additional argument MULTIBYTE and
170 pass it to normalize_filename.
171 (emacs_root_dir): Adjust.
173 * msdos.h (dostounix_filename): Adjust prototype.
175 * w32.h (dostounix_filename): Adjust prototype.
177 * msdos.c (dostounix_filename): Accept an additional argument and
179 (init_environment): Adjust callers of dostounix_filename.
181 * fileio.c (Ffile_name_directory, file_name_as_directory)
182 (directory_file_name, Fexpand_file_name)
183 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
185 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
187 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
188 variables, as egetenv is case-insensitive for DOS_NT.
190 * dired.c (file_name_completion): Don't call Fdirectory_file_name
191 with an encoded file name.
193 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
194 calls to dostounix_filename.
196 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
198 * unexw32.c (unexec): Adjust call to dostounix_filename.
200 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
202 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
205 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
208 * callproc.c (Fcall_process): Make sure program name in PATH and
209 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
210 is passed to exec/spawnve, which fails unless the file-name
213 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
214 even if w32-quote-process-args is nil.
216 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
218 Fix timestamp bug when write-region appends nothing (Bug#13149).
219 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
220 the file's time stamp doesn't change if Emacs happens to write nothing
221 to the file, and on a buggy file system this could cause Emacs to
222 incorrectly infer that the file system doesn't have the bug.
223 Avoid this problem by inhibiting the inference in this case.
225 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
227 * window.h (struct window): Convert base_line_number, base_line_pos
228 and column_number_displayed members from Lisp_Object to ptrdiff_t.

237 (wset_column_number_displayed, wset_region_showing): Remove.
238 (window_buffer_changed, mode_line_update_needed, redisplay_internal)

240 (try_window_reusing_current_matrix, try_window_id, display_line)
241 (display_mode_lines, decode_mode_spec): Adjust users.
242 * .gdbinit (pwinx): Do not print sequence_number.
244 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
246 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
247 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
248 * dired.c: Include <fcntl.h>.
249 (open_directory): New function, which uses open and fdopendir
250 rather than opendir. DOS_NT platforms still use opendir, though.

252 (file_attributes): New function, with most of the old Ffile_attributes.
253 (directory_files_internal, Ffile_attributes): Use it.

255 not dir name. All uses changed. Use fstatat rather than lstat +
257 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
258 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
259 (emacs_readlinkat): New function, with much of the old
260 Ffile_symlink_p, but with an fd argument for speed.
261 It uses readlinkat rather than careadlinkatcwd, so that it
262 need not assume the working directory.
263 (Ffile_symlink_p): Use it.
264 * filelock.c (current_lock_owner): Use emacs_readlinkat
265 rather than emacs_readlink.
266 * lisp.h (emacs_readlinkat): New decl.
267 (READLINK_BUFSIZE, emacs_readlink): Remove.
268 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
269 (emacs_norealloc_allocator, emacs_readlink): Remove.
270 This stuff is moved to fileio.c.
271 * w32.c (fstatat, readlinkat): New functions.
272 (careadlinkat): Don't check that fd == AT_FDCWD.
273 (careadlinkatcwd): Remove; no longer needed.
275 2013-01-31 Glenn Morris <rgm@gnu.org>
277 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
278 (Fwrite_region): Update for new choose_write_coding_system args.

282 2013-01-30 Eli Zaretskii <eliz@gnu.org>
284 * w32.c (sys_open): Zero out the flags for the new file descriptor.
285 (sys_close): Zero out the flags for the file descriptor before
286 closing it. (Bug#13546)
288 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
289 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
290 CharNextExA and CharPrevExA to iterate over file names encoded in
293 * w32.c (w32_get_long_filename, init_environment, readlink):
294 Support file names encoded in DBCS codepages.
295 (readlink): Use the current file-name-coding-system, not the ANSI
296 codepage, to decode and handle targets of symlinks.
298 2013-01-28 Eli Zaretskii <eliz@gnu.org>
300 * w32.c (opendir): Now accepts a 'const char *'.
302 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
304 Remove obsolete redisplay code. See the discussion at
305 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.

307 (Vredisplay_preemption_period): Likewise.
308 (update_frame, update_single_window, update_window, update_frame_1):
309 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
310 used, following the 2012-06-22 change.

324 2013-01-25 Eli Zaretskii <eliz@gnu.org>
326 * w32.c (max_filename_mbslen): New function.
327 (normalize_filename, readdir): Use it to detect locales where ANSI
328 encoding of file names uses a double-byte character set (DBCS).
329 If a DBCS encoding is used, advance by characters using
330 CharNextExA, instead of incrementing a 'char *' pointer. Use
331 _mbslwr instead of _strlwr. (Bug#13515)
333 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
334 request of memory reservation to 1.7GB. (Bug#13065)

344 Avoid redundant calls to strlen.
346 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
348 Drop async_visible and async_iconified fields of struct frame.

357 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
359 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
360 properly. Likewise for obscured.

374 * xdisp.c (message2, message2_nolog): Remove functions.
375 (message3, message3_nolog): Extract nbytes and multibyteness directly
376 from the string. Change all callers.
377 (message3_nolog): Don't set message_enable_multibyte since set_message
378 will reset it anyway.
379 (message1, message1_nolog): Use message3.
380 (vmessage): Use a stack allocated buffer rather than f->message_buf.
381 (with_echo_area_buffer): Remove last two arguments. Update all callers.
382 (set_message): Drop all but the second arg, which has to be a string.
383 (set_message_1): Simplify now that we know that a1 is NULL and the

397 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
398 * fileio.c (auto_save_error): Use message3 instead of message2.
399 * dispnew.c (adjust_frame_message_buffer): Remove function.
401 2013-01-23 Eli Zaretskii <eliz@gnu.org>
403 * w32term.c (w32fullscreen_hook): Account correctly for the screen
404 real estate used for the tool bar and the menu bar.
406 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
408 * insdel.c (prepare_to_modify_buffer): Force redisplay if
409 hidden buffer is prepared to modification (Bug#13164).
411 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>

429 * xdisp.c (mark_window_display_accurate): Simplify the loop
430 assuming that the only one of vchild, hchild or buffer window
431 slots is non-nil. Call mark_window_display_accurate_1 for
432 the leaf windows only.
433 (mark_window_display_accurate_1): Always assume leaf window.

456 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
458 * lisp.h (eabs): Define unconditionally (Bug#13419).
459 The old "#if !defined (eabs)" was an unnecessary revenant of back
460 when this macro was called "abs". Document 'eabs' better.
462 2013-01-19 Glenn Morris <rgm@gnu.org>
464 * fns.c (Frandom): Doc fix.
466 2013-01-19 Eli Zaretskii <eliz@gnu.org>
468 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
469 segfault when there are lots of overlays.
471 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
472 when there are lots of overlays. See
473 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
474 for the details and a way to reproduce.

478 * fileio.c: Use O_APPEND to append.
479 This corresponds better to the natural interpretation of "append",
480 and avoids the need to open the output file twice, or to invoke
481 lseek when APPEND is neither nil nor a number.
482 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
483 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
484 file possibly twice, and lseeking to its end; this avoids the
485 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
486 at the same time: the combination is never needed and apparently
487 it doesn't work with DOS_NT.
489 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
490 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
492 Allow floating-point file offsets.
493 Problem reported by Vitalie Spinu in
494 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
495 * fileio.c (emacs_lseek): Remove.
496 (file_offset): New function.
497 (Finsert_file_contents, Fwrite_region): Use it.
499 2013-01-19 Chong Yidong <cyd@gnu.org>
501 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
502 aborting on Fsignal (Bug#13289).
504 2013-01-19 Eli Zaretskii <eliz@gnu.org>
506 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
507 set_file_security as failure due to insufficient privileges.
508 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
509 (fstat): Return owner and group like 'stat' and 'lstat' do.
511 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
513 Work around bug in CIFS and vboxsf file systems (Bug#13149).
514 The bug was observed on Ubuntu operating inside a virtual machine,
515 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
516 The workaround introduces a race condition on non-buggy hosts,
517 but it's an unlikely race and anyway there's a nearly identical
518 nearby race that can't be fixed.
519 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
521 (Fwrite_region): Test for file system time stamp bug.
522 (init_fileio): New function.

532 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
533 for the error description produced by valgrind.
534 * fileio.c (read_non_regular): Rename to read_contents.
535 Free Lisp_Save_Value object used to pass parameters.
536 (read_non_regular_quit): Rename to read_contents_quit.
537 (Finsert_file_contents): Redesign internal file reading loop to adjust
538 gap and end positions after each read and so help make_gap to work
539 properly. Do not signal an I/O error too early and so do not leave
540 not yet decoded characters in a buffer, which was the reason of
541 redisplay crash. Use list2 to build return value. Adjust comments.
543 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
545 Close a race when statting and reading files (Bug#13149).
546 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
547 This avoids a race if the file is renamed between stat and open.
548 This race is not the problem originally noted in Bug#13149;
549 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

595 extraction from any Lisp_Save_Value slot. Add type checking.
596 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
597 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
598 * xselect.c: All users changed.

650 (save_excursion_restore): Adjust to match new layout. Use free_misc
651 because we do not allocate extra memory any more. Add eassert.
652 * print.c (print_object): New code to print Lisp_Save_Value. Do not
653 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

955 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
957 * keyboard.c (record_asynch_buffer_change): Initialize an event
958 only if it's really needed.
959 * frame.h (enum output_method): Remove output_mac member since
960 it's a leftover from the deleted code.
961 * frame.c (Fframep): Adjust user here ...
962 * terminal.c (Fterminal_live_p): ... and here.
963 * coding.c (Qmac): Now here because it's only used to denote
964 end-of-line encoding type.
965 (syms_of_coding): DEFSYM it.
966 * frame.h (Qmac): Remove duplicated declaration.
968 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
970 * window.c (select_window_1): Now static, since it's used only here.
972 2012-12-25 Eli Zaretskii <eliz@gnu.org>
974 * window.c (window_body_cols): Subtract display margins from the
975 window body width on TTYs as well. See
976 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
977 for the original report.
979 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
981 * xdisp.c (redisplay_window): Remove inner local variable
982 because the outer shadowed one has the same meaning.
983 * xterm.h (struct x_output): Remove toolbar_detached member since it's
985 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
986 (xg_create_tool_bar): Adjust users.
988 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
990 * buffer.h (BUF_COMPACT): New macro to follow the common style.
991 * buffer.c (Fget_buffer_create): Use it to set compact field of
992 struct buffer_text to avoid accessing an uninitialized value
993 when compact_buffer is called for the first time.
994 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
995 (Fset_buffer_modified_p): Use buffer_window_count to check
996 whether the buffer is displayed in some window.
997 * xdisp.c (message_dolog): Likewise.
999 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1001 * w32.c (acl_set_file): If setting the file security descriptor
1002 fails, and the new DACL is identical to the existing one, silently
1003 return success. This fixes problems for users backing up their
1004 own files without having the necessary privileges for setting
1005 security descriptors.
1007 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1009 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1010 after WaitForSingleObject returns normally. This expedites reader
1011 thread shutdown when delete_child triggers it.
1012 (reap_subprocess): More accurate commentary for why we call
1013 delete_child only when cp->fd is negative.
1015 * w32.c (sys_close): Do not call delete_child on a subprocess
1016 whose handle is not yet closed. Instead, set its file descriptor
1017 to a negative value, so that reap_subprocess will call
1018 delete_child on that subprocess when its SIGCHLD arrives.
1019 This avoids closing handles used for communications between sys_select
1020 and reader_thread, which doesn't give sys_select a chance to
1021 notice that the process exited and invoke the SIGCHLD handler for
1024 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1026 * nsfns.m (Fns_do_applescript): Run event loop until script has
1027 been executed (Bug#12969).
1028 (ns_run_ascript): Chech as_script for nil, set to nil after
1031 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1033 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1035 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1037 * w32term.c (w32fullscreen_hook): New function.
1038 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1040 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1042 * fileio.c (Finsert_file_contents): Doc fix.
1044 * w32proc.c (new_child, delete_child, find_child_pid): For a
1045 subprocess, consider its slot being in use as long as its process
1046 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1047 slot when a new process is started immediately after killing
1048 another one, without waiting enough time for the first process to
1049 be reaped and resources allocated for it be orderly freed.
1051 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1053 2012-12-21 Chong Yidong <cyd@gnu.org>
1055 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1057 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1059 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1061 * w32.c (get_name_and_id): Always pass NULL as the first argument
1062 of lookup_account_sid. Avoids crashes with UNC file names that
1063 refer to DFS domains, not to specific machine names. (Bug#12621)
1064 Remove now unused argument FNAME; all callers changed.
1065 (get_file_owner_and_group): Remove now unused argument FNAME; all
1068 2012-12-21 Chong Yidong <cyd@gnu.org>
1070 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1071 error for invalid chars, don't check for a nil return value.
1073 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1075 Avoid calls to CHAR_TO_BYTE if byte position is known.
1076 * editfns.c (make_buffer_string_both): Use move_gap_both.
1077 (Fbuffer_string): Use make_buffer_string_both.
1078 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1080 (buf_bytepos_to_charpos): Likewise.
1081 (charpos_to_bytepos): Remove.
1082 * fileio.c (Finsert_file_contents): Use move_gap_both.
1083 * search.c (Freplace_match): Likewise.
1084 * process.c (process_send_region): Likewise. Use convenient
1085 names for byte positions.
1086 * lisp.h (charpos_to_bytepos): Remove prototype.
1087 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1088 * insdel.c (move_gap): Likewise.
1090 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
1092 * xdisp.c (redisplay_internal): Remove now-unused local.
1094 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1096 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1097 (redisplay_internal): Don't bother selecting the frame to get the
1098 proper value of frame-local variables (bug#13225).
1100 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1102 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1103 Rename 4th argument since it may be buffer or string. Adjust comment.
1104 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1106 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1108 * coding.c (Fdetect_coding_region): Do not check start and end with
1109 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1110 (code_convert_region): Likewise.
1112 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1114 * w32.c (acl_get_file, acl_set_file): Run the file name through
1115 map_w32_filename, and resolve any symlinks in the file name, like
1117 (acl_set_file): Call revert_to_self, if any privileges were
1120 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1122 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1123 ($(BLD)/w32.$(O)): Update dependencies.
1125 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1127 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1128 propagate redisplay's scrolling (if any) to the right window.
1129 (redisplay_internal): Use ensure_selected_frame.
1130 (display_mode_lines): Complete last fix.
1131 * window.c (select_window_1): New func, extracted from select_window.
1132 (select_window): Use it.
1133 * window.h (select_window_1): Declare.
1135 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1137 Emulate Posix ACL APIs on MS-Windows.
1138 * w32.c: Include sddl.h and sys/acl.h.
1139 (SDDL_REVISION_1): Define if not already defined.
1140 (g_b_init_get_security_descriptor_dacl)
1141 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
1142 (g_b_init_is_valid_security_descriptor)

1155 (acl_free, acl_get_file, acl_set_file): New functions.
1157 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1159 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1161 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1162 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1163 for some of that bug's symptoms can now cause Emacs to abort.
1164 Remove the workaround.
1165 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1166 The bug that caused SIGCHLD to get lost has been fixed, and the
1167 workaround for it can now cause Emacs to abort.
1169 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1171 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1172 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1173 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1175 2012-12-16 Romain Francoise <romain@orebokech.com>
1177 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1178 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1179 and copy ACL entries of file in addition to SELinux context if set.
1180 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1182 * Makefile.in (LIBACL_LIBS): New macro.

1187 * fileio.c (internal_delete_file): Use bool for boolean.
1189 2012-12-15 Eli Zaretskii <eliz@gnu.org>
1191 Fix bug #13079 on MS-Windows with temp files not being deleted.

1194 (register_child): First argument is now pid_t.
1195 (record_infile, record_pending_deletion): New prototypes.
1197 * w32proc.c (new_child): Initialize input_file and
1198 pending_deletion members of the child.
1199 (delete_child): Delete the child's temporary input file, if any,
1200 that is pending deletion.
1201 (register_child): First argument is now pid_t.
1202 (record_infile, record_pending_deletion): New functions.
1203 (reap_subprocess): Fix a typo in DebPrint string.
1204 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1206 * fileio.c (internal_delete_file): Return an int again: non-zero
1207 if delete-file succeeds, zero otherwise.
1209 * lisp.h (internal_delete_file): Adjust prototype.
1211 * callproc.c (Fcall_process): Don't overwrite infile with result
1213 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1214 asynchronous subprocess, record the name of the input file name,
1216 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1217 delete the file, record it as pending deletion when the subprocess
1220 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1222 * editfns.c [HAVE_PWD_H]: Include grp.h.
1224 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

1228 Fix permissions bugs with setgid directories etc. (Bug#13125)
1229 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1230 to mark it as a placeholder. The old value was often wrong.
1231 The only user of this attribute has been changed to use
1232 file-ownership-preserved-p instead, with its new group arg.
1233 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1235 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

1240 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1242 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1243 try to get accurate owner and group information from NT file
1244 security APIs. This is to make most callers of 'stat' and
1245 'lstat', which don't need that information, much faster.
1247 * dired.c (Ffile_attributes) [WINDOWSNT]:
1248 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1249 owner and group information from 'lstat'.
1251 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1253 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1254 as that confuses set-auto-coding, so insist on the head-read
1255 returning the full 1024 bytes. Let lseek compute the tail offset;
1256 less work for us. Do not ignore I/O errors when reading the tail.
1258 * xdisp.c: Minor style fixes.
1259 (init_iterator): Hoist assignment out of if-expression.
1260 (markpos_of_region): Callers now test for sign, not for -1.
1262 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
1264 Minor redisplay optimization when the region length is zero.
1265 * xdisp.c (markpos_of_region): New function.
1266 (init_iterator): Do not highlight the region of zero length.
1267 (redisplay_window): Check whether the region is of non-zero length.
1268 (try_cursor_movement): Allow if the region length is zero.
1269 (try_window_reusing_current_matrix, try_window_id): Likewise.
1271 2012-12-13 Eli Zaretskii <eliz@gnu.org>
1273 * search.c (search_buffer): Check the inverse translations of each
1274 character in pattern when the buffer being searched is unibyte.
1277 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1279 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1280 files, fixing a regression from 24.2.
1281 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1283 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1285 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1286 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1287 Remove unnecessary S_ISLNK test, as (contra the comments) this
1288 function can't copy symlinks. Improve quality of error message
1289 when attempting to copy files that are neither regular files nor

1297 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1298 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1300 2012-12-12 Daniel Colascione <dancol@dancol.org>
1302 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1303 the dumped Emacs is not a sparse file, greatly improving Cygwin
1304 "make bootstrap" performance.
1306 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1308 * inotify.c (inotify_callback): Generate an Emacs event for every
1309 incoming inotify event.
1311 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1313 * xdisp.c (handle_face_prop): Fix logic of computing
1314 it->start_of_box_run_p.
1315 (append_space_for_newline): If the glyph row is R2L, reset the
1316 iterator's end_of_box_run_p flag before prepending the space glyph.
1317 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1318 iterator's start_of_box_run_p flag before prepending the stretch.
1319 (append_glyph, produce_image_glyph, append_composite_glyph)
1320 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1321 left_box_line_p and right_box_line_p flags of the glyph for R2L
1322 glyph rows. (Bug#13011)
1324 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1329 * window.c (replace_buffer_in_windows_safely): Do nothing
1330 if buffer is not shown in a window.

1336 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1337 encoded_file_name, which is what it is.
1339 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1341 Consistently use marker_position and marker_byte_position.

1350 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
1351 Replace direct access to marker fields with calls
1352 to marker_position and/or marker_byte_position.
1354 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
1356 * makefile.w32-in (SIG2STR_H): New macro.
1357 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
1358 ($(BLD)/w32notify.$(O)): Update dependencies.

1363 Windows file notification functionality unless WINDOWSNT.
1365 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1368 * w32fns.c (cache_system_info): Initialize the global hinst
1369 variable here so various initialization calls DTRT.
1371 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1372 (hinst): Remove unneeded extern declaration.
1373 (_start): Remove initialization of above variables; remove
1374 initialization of hinst, as cache_system_info now does that.
1376 * emacs.c (main): Call cache_system_info early in startup; we
1377 previously weren't calling it in Cygwin builds.
1379 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
1380 Teach the autoconf build system how to compile a Windows resource file
1381 and link it to Emacs.

1485 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
1487 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
1488 DWORD_PTR, for compatibility with 64-bit builds.

1516 * w32.c (unsetenv): Return 0 if the input string is too long.
1518 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1520 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1521 * alloc.c (xputenv): New function.
1522 * dbusbind.c (Fdbus_init_bus):
1524 * xterm.c (x_term_init):

1532 instead, use xputenv+unsetenv to set and restore TZ.
1533 (environbuf): Remove static var. All uses removed.
1534 (Fset_time_zone_rule): Do not save TZ and environ;
1535 no longer needed here.
1536 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1537 Move to inside set_time_zone_rule; they don't need file scope any more.
1538 (set_time_zone_rule): Maintain the TZ=value string separately.
1539 (syms_of_editfns): Don't initialize initial_tz;
1540 init_editfns now does it.
1541 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1542 * lisp.h (xputenv): New decl.
1544 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1546 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1548 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1550 * w32.c (unsetenv, sys_putenv): New functions.
1552 2012-12-08 Chong Yidong <cyd@gnu.org>

1555 informative (Bug#12992).
1557 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1559 Simplify get_lim_data.
1560 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1561 Remove USG and vlimit methods; no longer used these days.
1562 Add #error catchall just in case.
1564 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1565 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1566 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1567 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1568 (deleted_pid_list, Fdelete_process, create_process)
1569 (record_child_status_change, handle_child_signal, deliver_child_signal)

1573 (abbr_to_signal): New static function.
1574 (Fsignal_process): Use it to convert signal names to ints.

1585 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1587 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1588 This will cause a production Emacs to dump core instead of
1591 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1593 * frame.c (make_frame): Do not set window's buffer to t.
1594 * window.c (Fsplit_window_internal): Likewise. Previously it was
1595 used to indicate that the window is being set up. Now we use
1596 set_window_buffer for all new windows, so the condition in ...
1597 (Fset_window_buffer): ... is always true and can be removed.
1599 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1601 Convenient macro to check whether the buffer is hidden.
1602 * buffer.h (BUFFER_HIDDEN_P): New macro.
1603 * frame.c (make_frame): Use it. Adjust comment.
1604 * buffer.c (candidate_buffer): New function.
1605 (Fother_buffer, other_buffer_safely): Use it.
1607 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1609 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1610 if the child process is still running. Instead, exit the wait
1611 loop and return zero. (Bug#13086)
1613 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1615 * frame.h (x_char_width, x_char_height): Remove prototypes.

1629 * callproc.c, process.h (record_kill_process):
1630 New function, containing part of the old call_process_kill.
1631 (call_process_kill): Use it.
1632 This does not change call_process_kill's behavior.
1633 * process.c (Fdelete_process): Use record_kill_process to fix a
1634 race condition that could cause Emacs to lose track of a child.
1636 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1638 Avoid code duplication between prev_frame and next_frame.
1639 * frame.c (candidate_frame): New function. Add comment.
1640 (prev_frame, next_frame): Use it. Adjust comment.
1642 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1644 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1645 fails, signal an error instead of continuing with an empty
1647 Encode expanded temp file pattern before passing it to mkstemp or
1650 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1651 Encode the file name before passing it to dostounix_filename, in
1652 case it will downcase it (under w32-downcase-file-names).
1655 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1657 Minor call-process cleanups.
1658 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1659 at the same time as other platforms, to simplify analysis.
1660 No need for fd0_volatile since we have synch_process_fd.
1661 Avoid needless emacs_close; arg is always negative.
1663 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1665 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1668 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1670 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1671 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1672 and mouse_face_hidden members to a bitfields.
1673 * frame.h (struct frame): Remove set-but-not-used space_width member.
1674 (FRAME_SPACE_WIDTH): Remove.
1675 * nsterm.m, w32term.c, xterm.c: Adjust users.
1676 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1677 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1678 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1679 members to a bitfields.
1681 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1683 Don't let call-process be a zombie factory (Bug#12980).
1684 Fixing this bug required some cleanup of the signal-handling code.
1685 As a side effect, this change also fixes a longstanding rare race
1686 condition whereby Emacs could mistakenly kill unrelated processes,
1687 and it fixes a bug where a second C-g does not kill a recalcitrant
1688 synchronous process in GNU/Linux and similar platforms.
1689 The patch should also fix the last vestiges of Bug#9488,
1690 a bug which has mostly been fixed on the trunk by other changes.
1691 * callproc.c, process.h (synch_process_alive, synch_process_death)
1692 (synch_process_termsig, sync_process_retcode):
1693 Remove. All uses removed, to simplify analysis and so that
1694 less consing is done inside critical sections.
1695 * callproc.c (call_process_exited): Remove. All uses replaced
1696 with !synch_process_pid.
1697 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1698 These take the role of what used to be in unwind-protect arg.
1700 (block_child_signal, unblock_child_signal):
1701 New functions, to avoid races that could kill innocent-victim processes.
1702 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1703 (call_process_kill): Record killed processes as deleted, so that
1704 zombies do not clutter up the system. Do this inside a critical
1705 section, to avoid a race that would allow the clutter.
1706 (call_process_cleanup): Fix code so that the second C-g works again
1707 on common platforms such as GNU/Linux.
1708 (Fcall_process): Create the child process in a critical section,
1709 to fix a race condition. If creating an asynchronous process,
1710 record it as deleted so that zombies do not clutter up the system.
1711 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1712 light of these changes. Omit unnecessary call to emacs_close
1713 before failure, as the unwind-protect code does that.
1714 * callproc.c (call_process_cleanup):
1715 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1716 * process.c (record_deleted_pid): New function, containing
1717 code refactored out of Fdelete_process.
1718 (Fdelete_process): Use it.
1719 (process_status_retrieved): Remove. All callers changed to use
1720 child_status_change.
1721 (record_child_status_change): Remove, folding its contents into ...
1722 (handle_child_signal): ... this signal handler. Now, this
1723 function is purely a handler for SIGCHLD, and is not called after
1724 a synchronous waitpid returns; the synchronous code is moved to
1725 wait_for_termination. There is no need to worry about reaping
1726 more than one child now.
1727 * sysdep.c (get_child_status, child_status_changed): New functions.
1728 (wait_for_termination): Now takes int * status and bool
1729 interruptible arguments, too. Do not record child status change;
1730 that's now the caller's responsibility. All callers changed.
1731 Reimplement in terms of get_child_status.
1732 (wait_for_termination_1, interruptible_wait_for_termination):
1733 Remove. All callers changed to use wait_for_termination.
1734 * syswait.h: Include <stdbool.h>, for bool.
1735 (record_child_status_change, interruptible_wait_for_termination):
1737 (record_deleted_pid, child_status_changed): New decls.
1738 (wait_for_termination): Adjust to API changes noted above.
1740 * bytecode.c, lisp.h (Qbytecode): Remove.
1741 No longer needed after 2012-11-20 interactive-p changes.
1743 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1745 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1746 the scroll margin, move point outside the margin. (Bug#13055)
1748 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1750 * gtkutil.c (my_log_handler): New function.
1751 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1753 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1755 * lisp.h (modify_region): Rename to...
1756 (modify_region_1): ...new prototype.
1757 * textprop.c (modify_region): Now static. Adjust users.
1758 * insdel.c (modify_region): Rename to...
1759 (modify_region_1): ...new function to work with current buffer.
1760 Adjust comment and users. Use true and false for booleans.
1762 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1764 * alloc.c (free_save_value): New function.
1765 (safe_alloca_unwind): Use it.
1766 * lisp.h (free_save_value): New prototype.
1767 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1769 (save_excursion_restore): Adjust to match saved data structure.
1770 Use free_save_value to offload some work from GC. Drop obsolete
1773 2012-12-03 Chong Yidong <cyd@gnu.org>
1775 * fileio.c (Vauto_save_list_file_name): Doc fix.
1777 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1779 * w32fns.c: Remove prototype of atof.
1780 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1782 (file_dialog_callback): Make it UINT_PTR.
1784 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1787 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1788 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1791 2012-12-03 Glenn Morris <rgm@gnu.org>
1793 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1795 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1797 Fix xpalloc confusion after memory is exhausted.
1798 * alloc.c (xpalloc): Comment fix.
1799 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1800 and signals an error, do not clear charset_table_size, as
1801 charset_table is still valid.
1802 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1804 Use execve to avoid need to munge environ (Bug#13054).
1805 * callproc.c (Fcall_process):
1806 * process.c (create_process):
1807 Don't save and restore environ; no longer needed.
1808 * callproc.c (child_setup):
1809 Use execve, not execvp, to preserve environ.
1811 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1813 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1815 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1817 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1818 display for sliced images (Bug#10500).
1820 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1822 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1824 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1825 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1827 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1829 * xdisp.c (window_outdated): Remove eassert since it hits
1830 some suspicious corner cases (see Bug#13007 and Bug#13012).
1831 (mode_line_update_needed): New function.
1832 (redisplay_internal, redisplay_window): Use it.
1833 (ensure_selected_frame): New function.
1834 (redisplay_internal, unwind_redisplay): Use it.
1835 (redisplay_internal): Move comment about buffer_shared...
1836 (buffer_shared_and_changed): ...near to its real use.
1838 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1840 * callproc.c (Fcall_process): Don't misreport vfork failure.
1842 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1844 * callproc.c (Fcall_process): Fix vfork portability problems.
1845 Do not assume that fd[0], count, filefd, and save_environ survive
1846 vfork. Fix bug whereby wrong errno value could be reported for
1847 pipe failure. Some minor cleanups, too, as follows. Move buf and
1848 bufsize to the context where they're needed. Change new_argv to
1849 be of type char **, as this is more convenient and avoids casts.
1850 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1851 Now local constants, not macros.
1853 2012-11-18 Kenichi Handa <handa@gnu.org>

1898 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1899 were always defined.
1901 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1903 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1904 between bpos_covered and bpos_max. This fixes cursor display when
1905 several display strings follow each other.
1907 * .gdbinit (pgx): If the glyph's object is a string, display the
1908 pointer to string data, rather than the value of the string object
1909 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1911 * indent.c (Fvertical_motion): If the starting position is covered
1912 by a display string, return to one position before that, to avoid
1913 overshooting it inside move_it_to. (Bug#12930)
1915 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1917 * frame.h (struct frame): Remove display_preempted member
1918 since all users are dead long ago.
1919 * nsterm.h (struct x_output): Use the only dummy member.
1920 * w32menu.c (pending_menu_activation): Remove since not
1922 (set_frame_menubar): Adjust user.
1923 * w32term.h (struct x_output): Drop outdated #if 0 code.
1924 (struct w32_output): Use bitfields for explicit_parent,
1925 asked_for_visible and menubar_active members.
1926 Drop unused pending_menu_activation member.
1927 * xterm.h (struct x_output): Drop outdated #if 0 code.
1928 Use bitfields for explicit_parent, asked_for_visible,
1929 has_been_visible and net_wm_state_hidden_seen members.
1931 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1933 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1934 of a literal "/". (Bug#12955)
1935 (gl-stamp): Invoke fc.exe directly, not through cmd.
1937 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1939 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1940 * dired.c: Assume HAVE_DIRENT_H.
1941 (NAMLEN): Remove, replacing with ...
1942 (dirent_namelen): New function. All uses changed. Use the GNU macro
1943 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1944 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1945 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1946 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1948 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1949 * ndir.h: Rename to ../nt/inc/dirent.h.
1950 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1951 Do not include <dirent.h>; no longer needed.
1952 * w32.c: Include <dirent.h> rather than "ndir.h".
1954 2012-11-23 Chong Yidong <cyd@gnu.org>
1956 * xftfont.c (xftfont_open): Remove duplicate assignment.
1958 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1960 * alloc.c (Fgarbage_collect): Unblock input after clearing
1961 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1962 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1963 * msdos.c (IT_frame_up_to_date): Use it here...
1964 * w32term.c (w32_frame_up_to_date): ...here...
1965 * xterm.c (XTframe_up_to_date): ...and here...
1966 * nsterm.m (ns_frame_up_to_date): ...but not here.
1967 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1969 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1970 Do not check whether GC is in progress.
1972 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1974 * xdisp.c (window_buffer_changed): New function.
1975 (update_menu_bar, update_tool_bar): Use it to
1976 simplify large 'if' statements.
1977 (redisplay_internal): Generalize commonly used
1978 'tail' and 'frame' local variables.
1980 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1982 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1983 with Windows system header.
1985 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1987 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1988 * alloc.c: Assume unistd.h exists.
1989 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1990 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1991 (getwd) [USG]: Remove; no longer needed.
1992 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1993 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1994 * w32.h (getcwd): Remove decl.
1996 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1998 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1999 Make it set selected_window as well.
2000 (update_tool_bar): Use it.
2002 2012-11-21 Ken Brown <kbrown@cornell.edu>
2004 * emacs.c (main): Set the G_SLICE environment variable for all
2005 Cygwin builds, not just GTK builds. See
2006 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2008 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2010 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2011 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2012 Define for the MSVC compiler.
2014 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2016 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2017 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2018 dostounix_filename. Prevents crashes down the road, because
2019 dostounix_filename assumes it gets a unibyte string.
2020 Reported by Michel de Ruiter <michel@sentient.nl>, see
2021 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2023 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2025 Conflate Qnil and Qunbound for `symbol-function'.
2026 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
2027 * lread.c (init_obarray): Set `function' fields to Qnil.
2028 * eval.c (Fcommandp): Ignore Qunbound.
2029 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2030 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2031 Test NILP rather than Qunbound.
2032 (Ffmakunbound): Set to Qnil.
2033 (Fsymbol_function): Never signal an error.
2034 (Finteractive_form): Ignore Qunbound.
2036 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2038 * eval.c (interactive_p): Remove no-longer-used decl.
2040 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2042 * xdisp.c (buffer_shared): Adjust comment.
2043 (buffer_shared_and_changed): New function.
2044 (prepare_menu_bars, redisplay_internal): Use it to
2045 decide whether all windows or frames should be updated.
2046 (window_outdated): New function.
2047 (text_outside_line_unchanged_p, redisplay_window): Use it.
2048 (redisplay_internal): Likewise. Fix indentation.
2050 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2052 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2053 (syms_of_eval): Remove corresponding defsubr.
2054 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2056 2012-11-19 Daniel Colascione <dancol@dancol.org>
2058 * w32fns.c (Fx_file_dialog):
2059 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2060 cygwin_convert_file_name*.
2062 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2063 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2065 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2067 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2069 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2071 * w32select.c: Include w32common.h before w32term.h, so that
2072 windows.h gets included before w32term.h uses some of its
2073 features, see below.
2075 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2077 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2079 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2081 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2083 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2084 (ns_select): Return at once if events are held (Bug#12834).
2086 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2088 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2089 Needed following 2012-10-20 change. (Bug#12902)
2091 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2093 * w32proc.c (waitpid): Remove unused label get_result.
2095 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2097 * makefile.w32-in (SYSWAIT_H): New macro.
2098 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2099 ($(BLD)/sysdep.$(O)): Update dependencies.
2101 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2103 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2104 * callproc.c (relocate_fd): Assume F_DUPFD.
2105 * emacs.c, term.c (O_RDWR): Remove.
2106 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2107 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2108 * nsterm.m: Assume <fcntl.h> exists.
2109 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2110 (create_pty, Fmake_network_process, server_accept_connection)
2111 (wait_reading_process_output, init_process_emacs):
2113 (wait_reading_process_output): Put in a special case for WINDOWSNT
2114 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2115 It's not clear this is needed, but it's a more-conservative change.
2116 (create_process): Assume FD_CLOEXEC.
2117 (create_process, create_pty): Assume O_NOCTTY.
2118 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2119 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2120 Omit if not DOS_NT, since F_GETFL is not defined there.
2121 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2122 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2124 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2125 lack it, since gnulib guarantees this.
2126 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2128 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2130 * w32.c (faccessat): Pretend that directories have the execute bit
2131 set. Emacs expects that, e.g., in files.el:cd-absolute.
2133 * w32proc.c (create_child): Don't clip the PID of the child
2134 process to fit into an Emacs integer, as this is no longer a
2136 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2137 reaping only the process specified by PID argument, if that is
2138 positive. Use PID instead of dead_child to know which process to
2139 reap. Wait for the child to die only if WNOHANG is not in
2141 (sys_select): Don't set dead_child.
2143 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2144 as it is no longer needed.
2146 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2148 (record_child_status_change): Remove the setting of
2149 record_at_most_one_child for the !WNOHANG case.
2151 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2153 Fix problems in ns port found by static checking.
2154 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2155 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2156 not to process group.
2157 (ns_select): Use emacs_write, not write, as that's more robust
2158 in the presence of signals.
2159 (fd_handler:): Check for read errors.
2161 2012-11-16 Glenn Morris <rgm@gnu.org>
2163 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2165 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2167 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2169 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2171 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2172 use the same value of thread handle.
2173 (start_timer_thread): If the timer thread exited (due to error),
2174 clean up by closing the two handles it used. Duplicate the caller
2175 thread's handle here, so it gets duplicated only once, when
2176 launching the timer thread. Set priority of the timer thread, not
2178 (getitimer): Don't duplicate the caller thread's handle here.
2181 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2183 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2186 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2188 Remove no-longer-used pty_max_bytes variable.
2189 * process.c (pty_max_bytes): Remove; unused.
2190 (send_process): Do not set it.
2192 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2194 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2195 Update dependencies.
2197 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2199 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2200 This follows up on the 2012-09-29 patch that removed indirection
2201 for the 'function' field. Reported by Sergey Vinokurov in
2202 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2204 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2206 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2207 different name, as the MS runtime does not have such a function,
2208 and probably never will.) All callers changed. Ignore DIRFD
2209 value if PATH is an absolute file name, to match Posix spec
2210 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2213 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2215 * xdisp.c (echo_area_display, redisplay_internal):
2216 Omit redundant check whether frame_garbaged is set.
2218 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2220 Use faccessat, not access, when checking file permissions (Bug#12632).
2221 This fixes a bug that has been present in Emacs since its creation.
2222 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2223 which must set some sort of record. (Torek's bug report was against
2224 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2225 same common flaw.) See Torek's Usenet posting
2226 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2227 Posted: Fri Apr 8 14:18:56 1983.
2228 * Makefile.in (LIB_EACCESS): New macro.
2230 * callproc.c (init_callproc):
2231 * charset.c (init_charset):
2232 * fileio.c (check_existing, check_executable, check_writable)
2234 * lread.c (openp, load_path_check):
2235 * process.c (allocate_pty):
2237 Use effective UID when checking permissions, not real UID.
2238 * callproc.c (init_callproc):
2239 * charset.c (init_charset):
2240 * lread.c (load_path_check, init_lread):
2241 Test whether directories are accessible, not merely whether they exist.
2242 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2243 * fileio.c (check_existing, check_executable, check_writable)
2245 Use symbolic names instead of integers for the flags, as they're
2247 (check_writable): New arg AMODE. All uses changed.
2248 Set errno on failure.
2249 (Ffile_readable_p): Use faccessat, not stat + open + close.
2250 (Ffile_writable_p): No need to call check_existing + check_writable.
2251 Just call check_writable and then look at errno. This saves a syscall.
2252 dir should never be nil; replace an unnecessary runtime check
2253 with an eassert. When checking the parent directory of a nonexistent
2254 file, check that the directory is searchable as well as writable, as
2255 we can't create files in unsearchable directories.
2256 (file_directory_p): New function, which uses 'stat' on most platforms
2257 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2258 (Ffile_directory_p, Fset_file_times): Use it.
2259 (file_accessible_directory_p): New function, which uses a single
2260 syscall for efficiency.
2261 (Ffile_accessible_directory_p): Use it.
2262 * xrdb.c (file_p): Use file_directory_p.
2263 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2264 * lread.c (openp): When opening a file, use fstat rather than
2265 stat, as that avoids a permissions race. When not opening a file,
2266 use file_directory_p rather than stat.
2267 (dir_warning): First arg is now a usage string, not a format.
2268 Use errno. All uses changed.
2269 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2270 that merely introduced a race.
2271 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2272 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2273 and similarly for the other O_* flags.
2274 * w32.c (sys_faccessat): Rename from sys_access and switch to
2275 faccessat's API. All uses changed.
2276 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2277 (magic_db): Rename from magic_file_p.
2278 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2279 char *, so that we don't have to test for file existence
2280 separately from opening the file for reading. This removes a race
2281 fixes a permission-checking problem, and simplifies the code.
2283 (file_p): Remove; no longer needed.
2285 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2287 Omit glyphs initialization at startup.
2288 * dispnew.c (glyphs_initialized_initially_p): Remove.
2289 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2290 (Fredraw_frame): Move actual code from here...
2291 (redraw_frame): ...to here. Add eassert. Adjust comment.
2292 (Fredraw_display): Use redraw_frame.
2293 * xdisp.c (clear_garbaged_frames): Likewise.
2295 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2297 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2298 passed to pint2str and pint2hrstr to be at most the size of the
2299 frame's decode_mode_spec_buffer. This avoids crashes with very
2300 large values of FIELD_WIDTH argument to decode_mode_spec.
2303 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2305 Fix a race with verify-visited-file-modtime (Bug#12863).
2306 Since at least 1991 Emacs has ignored an mtime difference of no
2307 more than one second, but my guess is that this was to work around
2308 file system bugs that were fixed long ago. Since the race is
2309 causing problems now, let's remove that code.
2310 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2311 whose time stamp is off by no more than a second. Insist that the
2312 file time stamps match exactly.
2314 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2316 * frame.h (struct frame): Convert external_tool_bar member to
2317 1-bit unsigned bitfield.
2318 * termhooks.h (struct terminal): Remove mouse_moved member since
2319 all users are long dead. Adjust comment on mouse_position_hook.
2321 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2323 Simplify by using FOR_EACH_FRAME here and there.
2324 * frame.c (next_frame, prev_frame, other_visible_frames)
2325 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2326 * w32term.c (x_window_to_scroll_bar): Likewise.
2327 * window.c (window_list): Likewise.
2328 * xdisp.c (x_consider_frame_title): Likewise.
2329 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2330 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2331 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2332 * xmenu.c (menubar_id_to_frame): Likewise.
2333 * xselect.c (frame_for_x_selection): Likewise.
2334 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2335 (x_window_to_menu_bar): Likewise.
2336 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2338 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2340 * data.c (Qdefalias_fset_function): Now static.
2342 Another tweak to vectorlike_header change.
2343 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2344 Remove, and replace all uses with ...

2346 New functions, which respect C's aliasing rules better.
2348 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2350 * window.c (list4i): Rename from 'quad'. All uses changed.
2351 Needed because <sys/types.h> defines 'quad' on Solaris 10.

2365 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2367 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2368 amount when the scroll margins are too large. When scrolling
2369 backwards in the buffer, give up if cannot reach point or the
2370 scroll margin within a reasonable number of screen lines.
2371 Fixes point position in window under scroll-up/down-aggressively when
2372 point is positioned many lines beyond the window top/bottom.
2375 * ralloc.c (relinquish): If real_morecore fails to return memory
2376 to the system, don't crash; instead, leave the last heap

2390 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2392 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

2398 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2400 Fix recently introduced crash on MS-Windows (Bug#12839).
2401 * w32term.h (struct scroll_bar): Use convenient header.
2402 (SCROLL_BAR_VEC_SIZE): Remove.
2403 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2405 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2407 Tweak last vectorlike_header change.
2408 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2409 vectorlike object on the free list. This is introduced to avoid
2410 some (but not all) pointer casting and aliasing problems, see
2411 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2412 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

2416 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2418 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2419 been removed, so remove them here also.

2423 * doc.c (Fdocumentation): Handle new property
2424 dynamic-docstring-function to replace the old ad-advice-info.

2430 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2432 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2433 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2434 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

2439 Use same hash function for hashfn_profiler as for hash_string etc.
2440 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2441 * lisp.h (sxhash_combine): New inline function, with the contents
2442 of the old SXHASH_COMBINE.
2443 * profiler.c (hashfn_profiler): Use it, instead of having a
2444 special hash function containing a comparison that always yields 1.
2446 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2448 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2449 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2450 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2453 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2455 * image.c (xpm_make_color_table_h): Fix compiler error because
2456 make_hash_table changed.
2458 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2460 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2462 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2464 Use ad-hoc comparison function for the profiler's hash-tables.
2465 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2466 (make_log): Use them.
2467 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2468 call Fequal any more.

2477 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2478 (hash_lookup, hash_remove_from_table): Move assertion checking of
2479 hashfn result here. Check hash-equality before calling cmpfn.

2491 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2492 value of w32-scroll-lock-modifier is neither nil nor one of the
2493 known key modifiers. (Bug#12806)
2495 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2497 Shrink struct vectorlike_header to the only size field.
2498 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2500 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2501 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2502 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2503 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2504 information from the vector header. Adjust comment.

2519 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2520 (large_vectors): Change type to struct large_vector.
2521 (allocate_vector_from_block): Simplify.
2522 (PSEUDOVECTOR_NBYTES): Replace with...
2523 (vector_nbytes): ...new function. Adjust users.
2524 (sweep_vectors): Adjust processing of large vectors.
2525 (allocate_vectorlike): Likewise.
2526 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2527 Add easserts. Adjust XSETPVECTYPESIZE usage.
2528 (allocate_buffer): Use BUFFER_PVEC_INIT.
2529 (live_vector_p): Adjust to match large vector.
2530 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2531 * buffer.h (struct buffer): Add next member.
2532 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2534 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2535 * fns.c (internal_equal): Adjust to match enum pvec_type change.

2540 (xvecsize): New command.
2542 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2544 * keyboard.c (event_to_kboard): Do not dereference
2545 frame_or_window field of SELECTION_REQUEST_EVENT
2546 and SELECTION_CLEAR_EVENT events (Bug#12814).
2547 * xterm.h (struct selection_input_event): Adjust comment.
2549 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2551 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2552 such as Scroll Lock, if the respective keys are treated as
2553 function keys, not as modifiers. This avoids destroying non-ASCII
2554 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2556 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2558 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2560 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2562 Restore some duplicate definitions (Bug#12814).
2563 This undoes part of the 2012-11-03 changes. Some people build
2564 with plain -g rather than with -g3, and they need the duplicate
2565 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2566 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2567 Define as macros, as well as as enums or as constants.
2569 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2571 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2572 to keypad keys (Bug#12816).
2574 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2576 Minor adjustments of recently-changed frame functions.
2577 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2578 known to be a frame (we're in the FRAMEP branch).
2579 * lisp.h (Qframep): Remove decl. frame.h declares this.
2580 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2581 since they're meant for Lisp fixnum values.
2583 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2585 * window.c (Fwindow_combination_limit): Revert to the only
2586 required argument and adjust docstring as suggested in
2587 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2588 by Martin Rudalics <rudalics@gmx.at>.
2590 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2592 Widely used frame validity and checking functions.
2593 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2594 * frame.c (decode_live_frame, decode_any_frame): New functions.
2595 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2596 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2597 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2598 (Fframe_pointer_visible_p): Use decode_any_frame.
2599 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2600 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2601 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2602 (Fframe_focus): Likewise. Allow zero number of arguments.
2604 (frame_buffer_list, frame_buffer_predicate): Remove.
2605 * lisp.h (frame_buffer_predicate): Remove prototype.
2606 * buffer.c (Fother_buffer): Use decode_any_frame.
2607 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2608 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2609 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2610 (Fclose_font, Ffont_info): Use decode_live_frame.
2611 * fontset.c (check_fontset_name): Likewise.
2612 * terminal.c (Fframe_terminal): Likewise.
2613 * w32fns.c (check_x_frame): Likewise.
2614 * window.c (Fminibuffer_window, Fwindow_at)
2615 (Fcurrent_window_configuration): Likewise.
2616 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2617 Likewise. Allow zero number of arguments. Adjust docstring.
2618 * dispnew.c (Fredraw_frame): Likewise.
2619 * xfaces.c (frame_or_selected_frame): Remove.
2620 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2621 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2622 (Fframe_face_alist): Use decode_live_frame.
2623 * xfns.c (check_x_frame): Likewise.
2625 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2627 * window.c (quad): New function.
2628 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2629 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2630 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2631 (Fwindow_line_height): Use it.
2632 (Fwindow_fringes): Use list3.
2633 (Fwindow_scroll_bars): Use list4.
2634 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2635 (Fwindow_combination_limit): Allow zero number of arguments.
2637 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2639 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2641 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2642 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2643 file descriptor 2 for standard error. (Bug#12805)
2645 2012-11-05 Chong Yidong <cyd@gnu.org>
2647 * process.c (wait_reading_process_output): Revert previous change.
2649 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2651 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2652 This removes code that has been obsolete since around 1990.
2653 * callproc.c (Fcall_process):
2655 * process.c (create_process):
2656 * term.c (dissociate_if_controlling_tty):
2657 Assume setsid exists.
2658 * callproc.c (child_setup): Assume setpgid exists and behaves as
2659 per POSIX.1-1988 or later.
2660 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2661 * emacs.c (shut_down_emacs):
2662 * sysdep.c (sys_suspend, init_foreground_group):
2663 Assume getpgrp behaves as per POSIX.1-1998 or later.
2664 * msdos.c (setpgrp): Remove.
2665 (tcgetpgrp, setpgid, setsid): New functions.
2666 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2667 * term.c (no_controlling_tty): Remove; unused.
2668 * w32proc.c (setpgrp): Remove.
2669 (setsid, tcgetpgrp): New functions.
2671 Simplify by assuming __fpending.
2672 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2673 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2674 Do not assume that __fpending's result fits in int.
2676 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2678 Remove EMACS_OUTQSIZE+sleep hack.
2679 * dispnew.c (update_frame_1): Remove hack for terminals slower
2680 than 2400 bps, which throttled Emacs by having it sleep.
2681 This code hasn't worked since at least 2007, when the multi-tty stuff
2682 was added, and anyway those old terminals are long dead.
2683 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2684 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2686 Fix data-loss with --version (Bug#9574).
2687 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2688 as we can't assume that emacs_strerror is initialized, and strerror
2689 is good enough here.
2690 (main): Invoke atexit earlier, to catch earlier instances of
2691 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2693 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2695 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2696 (keyDown): Remap keypad keys to X11 virtual key codes.
2698 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2700 Fix data-loss with --batch (Bug#9574).
2701 * emacs.c: Include <close-stream.h>.
2702 (close_output_streams): New function.
2703 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2704 and handles errors appropriately.
2705 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2708 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2709 The symptom is a diagnostic "GLib-WARNING **: In call to
2710 g_spawn_sync(), exit status of a child process was requested but
2711 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2712 waitpid(), so exit status can't be returned." The diagnostic
2713 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2714 The real bug is a race condition between Emacs and glib: Emacs
2715 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2716 so that glib can't find it. Work around the bug by invoking
2717 waitpid only on subprocesses that Emacs itself creates.
2718 * process.c (create_process, record_child_status_change):
2719 Don't use special value -1 in pid field, as the caller now must
2720 know the pid rather than having the callee infer it.
2721 The inference was sometimes incorrect anyway, due to another race.
2722 (create_process): Set new 'alive' member if child is created.
2723 (process_status_retrieved): New function.
2724 (record_child_status_change): Use it.
2725 Accept negative 1st argument, which means to wait for the
2726 processes that Emacs already knows about. Move special-case code
2727 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2728 processes that have already been waited for, by testing and
2729 clearing new 'alive' member.
2730 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2731 now does this internally.
2732 (handle_child_signal): Let record_child_status_change do all
2733 the work, since we do not want to reap all exited child processes,
2734 only the child processes that Emacs itself created.
2735 * process.h (Lisp_Process): New boolean member 'alive'.
2737 Omit duplicate definitions no longer needed with gcc -g3.
2738 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2739 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2740 Define only as macros. There's no longer any need to also define
2741 these symbols as enums or as constants, since we now assume
2742 gcc -g3 when debugging.
2744 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2746 * lisp.mk: Adjust comments to the fact that term/internal is now
2747 loaded from loadup.el.
2749 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2750 (msdos_fatal_signal): New function.
2751 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2754 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2755 for GCC versions before 4.
2756 (emacs_raise): Define to call msdos_fatal_signal.
2758 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2759 iterator when starting in the middle of a display or overlay
2762 2012-11-03 Chong Yidong <cyd@gnu.org>
2764 * process.c (wait_reading_process_output): Clean up the last
2767 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2769 * process.c (wait_reading_process_output): Avoid a race condition
2770 with SIGIO delivery (Bug#11536).
2772 2012-11-03 Chong Yidong <cyd@gnu.org>
2774 * buffer.c (cursor_type): Untabify docstring.
2776 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2778 * frame.h (struct frame): Drop can_have_scroll_bars member
2779 which is meaningless for a long time. Adjust comments.

2824 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2826 Remove pad from struct input_event.
2827 * termhooks.h (struct input_event): Remove padding field.
2829 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2830 member is never cons for a long time. Adjust comment.
2831 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2832 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2833 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2834 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2836 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2838 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)

2842 Fix crash when using Emacs as commit editor for git (Bug#12697).
2843 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2844 and it is configured in conf_post.h.
2845 (Fcall_process): Don't invoke both setsid and setpgid; the former
2846 is enough, if it exists.
2847 * callproc.c (Fcall_process, child_setup):
2848 * process.c (create_process): Use setpgid.
2849 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2851 * dispnew.c (init_display): Initialize the foreground group
2852 if we are running a tty display.

2865 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2867 * minibuf.c (read_minibuf): Restore current buffer since
2868 choose_minibuf_frame calling Fset_frame_selected_window may

2880 2012-10-29 Daniel Colascione <dancol@dancol.org>
2882 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2883 In preparation for fixing bug#12739, move these functions from
2886 * coding.h, coding.c: ... to here, and compile them only when
2887 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2888 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2890 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2892 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.

2907 remove last_appdefined_event (Bug#12698).
2909 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2911 * frame.c (x_set_font): Catch internal error.
2913 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2915 Avoid overflow in w32 implementation of interval timers.
2916 When possible, for ITIMER_PROF count only times the main thread
2918 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2919 'volatile ULONGLONG' types. All the other data which was
2920 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2921 (GetThreadTimes_Proc): New typedef.
2922 (w32_get_timer_time): New function, returns a suitable time value
2924 (timer_loop): Enter critical section when accessing ULONGLONG
2925 values of the itimer_data struct, as these accesses are no longer
2926 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2927 Remove unused variable.
2928 (init_timers): Initialize s_pfn_Get_Thread_Times.
2929 (start_timer_thread): Don't assign itimer->caller_thread here.

2936 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2937 mouse movement events if the menu bar is active. This avoids
2938 producing a busy "hour-glass" cursor by Windows if the mouse
2939 pointer is positioned over a tooltip shown for some menu item.
2941 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2943 Don't assume process IDs fit in int.
2944 * emacs.c (shut_down_emacs) [!DOS_NT]:
2945 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2946 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2947 Use pid_t, not int, to store process IDs, as 'int'
2948 is not wide enough on a few platforms (e.g., AIX and IRIX).
2950 2012-10-23 Kenichi Handa <handa@gnu.org>
2952 The following change is to make face-font-rescale-alist work

2973 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2975 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>

2978 * frame.c (Fmouse_position, Fmouse_pixel_position):
2979 * xdisp.c (produce_stretch_glyph):
2980 Declare local vars only when they're needed.
2981 This is clearer and avoids a warning on OpenBSD about unused vars.

2983 This is safer, and avoids OpenBSD warnings about unused vars.
2984 * keyboard.c (record_menu_key): Remove unnecessary decl.
2985 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2986 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2987 as our definition clashes with OpenBSD's.
2988 * xfaces.c (load_face_colors, check_lface_attrs)
2989 (get_lface_attributes_no_remap, get_lface_attributes)
2990 (lface_fully_specified_p, x_supports_face_attributes_p)
2991 (tty_supports_face_attributes_p, face_fontset, realize_face)
2992 (realize_x_face, realize_tty_face):
2993 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2994 merely Lisp_Object *. This is more informative and avoids
2995 a warning on OpenBSD about accessing beyond an object's size.
2997 2012-10-20 Chong Yidong <cyd@gnu.org>
2999 * lread.c (Fload): Doc fix (Bug#12592).

3025 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3026 (staticpro): If we run out of staticpro slots, die with an
3027 informative error instead of just calling emacs_abort.

3283 (detect_input_pending_run_timers):
3284 * process.c (wait_reading_process_output):
3285 Use unsigned for counter where wraparound-on-overflow is desired,
3286 since unsigned is guaranteed to have that behavior and signed is not.
3287 (read_char): Use ptrdiff_t for string length.
3288 (get_input_pending): Remove first argument, since it was always
3289 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3290 and behave as if it had that value. Return new value of
3291 input_pending. All callers changed.
3292 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3293 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
3295 * keymap.c (push_key_description): Omit last arg, which was always 1.
3296 All callers changed.
3298 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

3309 initializer for PVEC_NORMAL_VECTOR.
3311 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>

3314 * termopts.h (flow_control, meta_key): Remove unused decls.
3315 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
3316 Don't include termopts.h.
3318 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3320 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3322 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3324 * commands.h (immediate_quit): Remove duplicate decl.
3326 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3328 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3331 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3333 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3335 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3336 match what GetLastError returns. Explain why the function is
3339 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3340 'is_tooltip_frame', to avoid confusion with its global namesake.
3342 2012-10-08 Daniel Colascione <dancol@dancol.org>
3344 * xdisp.c (start_hourglass): Call w32_note_current_window when
3345 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3346 build that caused Emacs to display the hourglass cursor forever.
3348 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3349 which is broken under remote desktop, calculate the number of
3350 colors available for a display based on the display's number of
3351 planes and number of bits per pixel per plane. (bug#10397).
3353 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3355 * nsfont.m (Vfonts_in_cache): New variable.
3356 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3357 are used. Add cached fonts to Vfonts_in_cache.
3358 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3360 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3362 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3364 (FONT_H): Define after FRAME_H.
3365 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3366 Update dependencies.
3368 * w32term.c: Remove leftover declaration of keyboard_codepage.
3370 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3372 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3373 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3374 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.

3381 ($(BLD)/w32menu.$(O)):
3382 ($(BLD)/w32proc.$(O)): Add w32common.h.
3384 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3386 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3388 2012-10-08 Daniel Colascione <dancol@dancol.org>
3390 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3391 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3392 accidental message numbering hole. Change other messages to
3395 * w32select.h (HAVE_W32SELECT): Remove.
3397 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3398 w32common.h instead of w32heap.h.

3408 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3409 (w32_minor_version, w32_build_number, w32_subtype):
3410 Remove duplicate definitions.
3412 * w32fns.c: Include w32common.h; include w32heap.h only in
3415 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3416 Use `report_file_error' instead of `error' in order to better
3417 inform users of what went wrong. Increase NTGUI_UNICODE file
3418 dialog box file name length to 32k, the maximum allowed by the NT
3421 * w32common.h: New file.
3422 (ROUND_UP, ROUND_DOWN, get_page_size)
3423 (get_allocation_unit, get_processor_type, get_w32_major_version)
3424 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3425 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3426 (OS_NT, os_subtype, cache_system_info): Move here.
3428 * unexw32.c, unexcw.c: Include w32common.h.
3430 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3431 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3432 to call syms_of_w32select.
3434 * cygw32.h: Remove obsolete EXFUN declarations.
3436 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3438 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3439 of w32inevt.o from SOME_MACHINE_OBJECTS.
3441 2012-10-08 Daniel Colascione <dancol@dancol.org>
3443 * image.c: Permanent fix for JPEG compilation issue --- limit
3444 jpeglib `boolean' redefinition to Cygwin builds.
3446 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3448 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3450 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3453 2012-10-08 Daniel Colascione <dancol@dancol.org>
3455 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3456 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3457 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3458 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3459 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3460 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3461 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3462 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3463 now a supported configuration.
3465 * Makefile.in: consolidate image variables into LIBIMAGE; add
3466 W32_OBJ and W32_LIBS. Compile new files.
3469 (_DebPrint) declare tracing facility for W32 debugging. We need
3470 to unify tracing later.
3472 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3473 unconditional use of W32 Unicode functions. Cygwin runs only on
3474 100% Unicode operating systems.
3476 * cygw32.c: New file. Define Cygwin-specific facilities.
3477 (Fcygwin_convert_path_to_windows)
3478 (Fcygwin_convert_path_from_windows): New user functions for
3479 accessing Cygwin path-munging routines.
3481 * cygw32.h: New file.
3482 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3483 UTF-16LE strings temporarily inside non-Lisp-visible string
3486 (w32_strerror): Just what it says on the tin.
3488 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3489 also run for Cygwin; both systems have the same problem with using
3490 GUI facilities in a forked child. Also call syms_of_cygw32,
3491 syms_of_w32select in correct places.
3493 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3494 needs fork-then-exec for daemon launching.
3496 * font.h: Include frame.h.
3498 * image.c: Use the image library cache machinery only when we're
3499 compiling for native WINDOWSNT; Cygwin can use shared libraries
3500 like any other Unixlike system.
3502 * keyboard.c: Clarify a comment regarding the input loop.
3504 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3505 functions directly instead of trying to detect at runtime that our
3506 host operating system supports them. We make this change for two
3507 reasons: Cygwin lacks support for the multibyte character
3508 conversion functions used by the legacy menu code, and Cygwin
3509 never needs to rely on non-Unicode APIs.
3511 * unexw32.c (hinst): Declare extern.
3513 * w32.c: Change header order;
3514 (w32_strerror): Move to w32fns.c because we need it for
3515 non-WINDOWSNT builds.
3517 * w32.h: Add #error macro to make sure we don't include w32.h for
3518 Cygwin builds. Remove w32select declarations.
3520 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3521 w32fns.c. w32console.c is WINDOWSNT-only.
3523 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3524 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3526 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3527 (w32_major_version, w32_minor_version, w32_build_number)
3528 (os_subtype, sound_type): Define here
3529 (w32_defined_color): Make color parameter const for consistency
3530 with other _defined_color functions.
3531 (w32_createwindow): Unconditionally call w32_init_class instead of
3532 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3533 through the code is complex and unnecessary because class
3534 registration is practically free.
3535 (w32_name_of_message): New EMACSDEBUG-only function.
3536 (Fset_message_beep): Move here
3537 (Fx_open_connection): Require that the display name for Windows be
3538 "w32" for consistency, emacsclient disambiguation, and maybe, one
3539 day, multi-window-system support.
3540 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3541 Cygwin files for W32 GUI facilities, since these clearly don't
3542 expect Cygwin names.
3543 (_DebPrint): Define.
3544 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3545 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3546 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3547 (w32_last_error): Remove.
3549 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3551 * w32heap.c (syspage_mask): Declare here.
3552 (cache_system_info): Remove.
3554 * w32inevt.c (faked_key): Define globally, not statically.
3555 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3556 (w32_console_toggle_lock_key): Move to w32fns.c.
3558 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3560 * w32proc.c (_DebPrint): Move to w32fns.c.
3561 * w32select.c: Include string.h, stdio.h for Cygwin.
3562 * w32select.h: New File.
3564 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3566 (w32_message_fd): New variable. Under Cygwin, holds the file
3567 descriptor the system used to tell us about pending thread
3570 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3571 that prevented compilation under non-WINDOWSNT systems.
3573 (w32_initialize): Open /dev/windows and assign it to
3574 w32_message_fd. Provide w32 feature.
3576 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3577 (WM_EMACS_INPUT_READY): add.
3578 (prepend_msg, w32_message_fd): Declare globally.
3581 (keyboard_handle): Use only when WINDOWSNT.
3582 (notify_msg_ready): New function. Posts a message to the main
3583 thread's message queue under CYGWIN, which wakes up the main
3584 thread from select(2) by making the /dev/windows file descriptor
3585 ready. Under WINDOWSNT, it sets an event the same way the old
3588 (post, prepend_msg): Actually call notify_msg_ready instead of
3589 setting the input event directly.
3591 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3593 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3594 but it still has blocs in it, don't return it to the system,
3595 instead of aborting. (Bug#12402)
3597 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3599 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3601 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3602 MAC_OS_X_VERSION_10_6.

3607 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3609 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3610 MAC_OS_X_VERSION_10_4.
3612 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3613 MAC_OS_X_VERSION_10_2.
3615 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3617 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3618 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3620 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3621 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3622 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3623 Remove ns_in_resize check.
3624 (ns_clear_frame_area): Remove resize handle code.
3626 * nsfns.m (ns_in_resize): Remove.
3627 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3628 Remove ns_in_resize check.
3630 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3632 Improve sys_siglist detection.
3633 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3634 defined as a macro, as is done in Solaris.
3635 (sys_siglist_entries): New macro.
3636 (save_strsignal): Use it.
3637 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3638 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3640 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3642 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3643 fullscreen/Fullscreen.
3645 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3646 tobar_height is new.
3648 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3649 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3650 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3651 (windowDidResize:): Check for correct window if old style fullscreen.
3652 Capitalize word in comment. Remove incorrect comment.
3653 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3654 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3655 error in drawing background.
3656 (toggleFullScreen:): Remove comment. Rearrange calls.
3657 Set toolbar values to zero, save old height in tobar_height.
3658 Restore tool bar height when leaving fullscreen.
3659 (canBecomeMainWindow): New function.
3661 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3663 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3665 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3667 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3669 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3670 that time stamps of directories could also be changed.
3671 Don't request the too broad GENERIC_WRITE, only the more restrictive
3672 FILE_WRITE_ATTRIBUTES access rights.
3674 * fileio.c (Fset_file_times): Special-case ignoring errors for
3675 directories only on MSDOS, not on MS-Windows.
3677 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3679 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3681 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3683 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3684 see whether CreateFile failed.
3686 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3688 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3689 to avoid similar races.
3690 * keyboard.c (pending_signals): Now bool, not int.
3692 Port timers to OpenBSD, plus check for timer failures.
3693 OpenBSD problem reported by Han Boetes.
3694 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3696 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3697 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3698 like OpenBSD, which has timer_settime but does not declare it.
3699 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3700 whether to use itimerspec-related primitives. All uses of
3701 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3703 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3705 * profiler.c (handle_profiler_signal): Fix a malloc race
3706 that caused Emacs to hang on Fedora 17 when profiling Lisp.

3714 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3715 consistent with the change in return value of 'safe_strsignal'.
3717 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3719 Prefer plain 'static' to 'static inline' (Bug#12541).
3720 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3721 (bidi_set_sor_type, bidi_push_embedding_level)
3722 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

3729 Now 'static', not 'static inline'.
3731 Count overruns when profiling; change units to ns.
3732 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3733 Give extra weight to samples after overruns, to attempt to count
3734 the time more accurately.
3735 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3736 the underlying primitives nominally do ns.
3737 (Fprofiler_cpu_start): Document the change. Mention that
3738 the sampling intervals are only approximate.
3740 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3742 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

3758 Fix a malloc race condition involving strsignal.
3759 A signal can arrive in the middle of a malloc, and Emacs's signal
3760 handler can invoke strsignal, which can invoke malloc, which is
3761 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3762 Fix it by altering the signal handler so that it does not invoke
3764 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3765 * process.c (status_message): Use const pointer, in case strsignal
3766 is #defined to safe_strsignal.
3767 * sysdep.c (sys_siglist, init_signals): Always define and
3768 initialize a substitute sys_siglist if the system does not define
3769 one, even if HAVE_STRSIGNAL.
3770 (safe_strsignal): Rename from strsignal. Always define,
3771 using sys_siglist. Return a const pointer.
3772 * syssignal.h (safe_strsignal): New decl.
3773 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3775 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3777 * w32proc.c (timer_loop): Fix code that waits for timer
3778 expiration, to avoid high CPU usage.
3780 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3782 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3783 (sweep_weak_table): Remove redundant prototypes.
3785 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3787 * emacs.c: Move the inclusion of TERM_HEADER after including
3788 windows.h on WINDOWSNT. This avoids compilation problems with
3791 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3793 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3794 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3795 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3796 as the previous version used 'void *'.
3798 * ralloc.c (ROUNDUP): Fix last change.
3799 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3802 * w32proc.c <disable_itimers>: New static flag.
3803 (init_timers): Initialize it to zero, after creating the critical
3804 sections used by the timer threads.
3805 (term_timers): Set to 1 before deleting the critical sections.
3806 (getitimer, setitimer): If disable_itimers is non-zero, return an
3807 error indication without doing anything. Reported by Fabrice
3808 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3809 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3811 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3814 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3815 term_ntproc after all the other bookkeeping, to get timers working
3816 as long as possible.
3818 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3820 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3821 Suggested by Juri Linkov in
3822 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3824 Prefer plain 'static' to 'static inline' (Bug#12541).
3825 With static functions, modern compilers inline pretty well by
3826 themselves; advice from programmers often hurts as much as it helps.
3827 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3828 this change shrinks the text size of the Emacs executable by 1.1%
3829 without affecting CPU significantly in my benchmark.

3910 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3912 Revert the FOLLOW-SYMLINKS change for file-attributes.
3913 Doing it right would require several changes to Tramp, and there's
3914 not enough time to get that tested before the freeze today.
3915 * dired.c (directory_files_internal, Ffile_attributes):
3918 * frame.c (x_report_frame_params): Port better to wider ints.
3919 Do not assume that EMACS_UINT is the same width as uprintmax_t,

3952 * w32.c (init_environment, get_emacs_configuration): Support AMD64
3954 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
3955 compatibility with x64.
3957 * vm-limit.c (lim_data): Now size_t.
3958 (check_memory_limits): Adjust prototypes of real_morecore and
3959 __morecore to receive argument of type ptrdiff_t. Use size_t for
3960 five_percent and data_size.
3962 * unexw32.c: Use DWORD_PTR instead of DWORD for file-scope
3963 variables, for compatibility with x64.

3986 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows

4013 sigfillset, and sigprocmask are no longer no-ops.
4014 (sigismember): New function.
4015 (struct itimer_data): New definition.
4016 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)

4045 2012-09-30 Kenichi Handa <handa@gnu.org>
4047 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
4048 to the buffer relocation which may be caused by ccl_driver.

4105 2012-09-30 Eli Zaretskii <eliz@gnu.org>
4107 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
4108 HAVE_TIMER_SETTIME is defined.
4110 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
4112 Profiler improvements: more-accurate timers, overflow checks.
4113 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4114 signal.h, setjmp.h. Include systime.h instead.
4115 (saturated_add): New function.
4116 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

4122 All uses changed to store the new value.
4123 (handle_profiler_signal): Rename from sigprof_handler_1,
4124 for consistency with other handlers. Do not check whether
4125 cpu_log is a hash-table if garbage collecting, since it
4126 doesn't matter in that case.
4127 (deliver_profiler_signal): Rename from sigprof_handler,
4128 for consistency with other handlers.
4129 (setup_cpu_timer): New function, with much of what used to be in
4130 Fprofiler_cpu_start. Check for out-of-range argument.
4131 Prefer timer_settime if available, and prefer
4132 thread cputime clocks, then process cputime clocks, then
4133 monotonic clocks, to the old realtime clock. Use make_timeval
4134 to round more-correctly when falling back to setitimer.
4135 (Fprofiler_cpu_start): Use it.
4136 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4137 Don't assume that passing NULL as the 2nd argument of setitimer
4138 is the same as passing a pointer to all-zero storage.
4139 Ignore SIGPROF afterwards.
4140 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4141 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4142 non-fatal signal handlers. Ignore SIGPROF on startup.
4143 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4144 in profiler.c, since sysdep.c now uses it.
4146 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4166 (Frun_hook_with_args_until_failure): Doc fixes.
4168 2012-09-28 Eli Zaretskii <eliz@gnu.org>
4170 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
4171 Qautomatic_redisplay and change the symbol name. All users changed.

4184 * Makefile.in (LIB_TIMER_TIME): New macro.
4186 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):

4198 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
4200 * character.h (MAYBE_UNIFY_CHAR): Remove.
4201 * charset.c, charset.h (maybe_unify_char): Now static.
4202 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4203 Since this stuff is now private to charset.c, there's no need for
4204 a public macro and no need to inline by hand.

4233 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4235 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4237 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4239 Prefer POSIX timers if available.
4240 They avoid a race if the timer is too close to the current time.
4241 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4242 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4243 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4245 2012-09-25 Eli Zaretskii <eliz@gnu.org>

4250 STRING_CHAR_ADVANCE.
4252 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4254 Move Vlibrary_cache to emacs.c and reset before dumping.
4256 * lisp.h (reset_image_types): Declare.
4257 [WINDOWSNT] (Vlibrary_cache): Declare.
4259 * image.c (reset_image_types): New function.
4261 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

4268 * w32.h (Vlibrary_cache): Do not declare.
4270 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4272 * w32proc.c (sys_signal): Handle all signals defined by the
4273 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4274 handlers for signals supported by Windows. Don't override
4275 term_ntproc as the handler for SIGABRT.
4276 (sigaction): Rewrite to call sys_signal instead of duplicating its
4278 (sys_kill): Improve commentary.
4280 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4281 consistency with a signature of a signal handler. All callers
4283 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4284 install term_ntproc as a signal handler for SIGABRT, as that
4285 should be done by the dumped Emacs.
4287 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4289 * w32select.c (term_w32select): Protect against repeated
4290 invocation by setting clipboard_owner to NULL after calling
4293 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
4294 and term_ntproc to their modified signatures.
4296 * character.c (char_string, string_char): Remove calls to
4297 MAYBE_UNIFY_CHAR. See the discussion starting at

4301 2012-09-25 Chong Yidong <cyd@gnu.org>
4303 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4305 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4307 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4308 when encountering an unknown bytecode.
4310 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4312 image.c, indent.c: Use bool for booleans.
4313 * dispextern.h (struct image_type): Members valid_p, load, init
4314 now return bool, not int. All uses changed.
4315 * image.c: Omit unnecessary static decls.
4316 (x_create_bitmap_mask, x_build_heuristic_mask):
4317 Return void, not int, since callers don't care about the return value.

4348 2012-09-24 Chong Yidong <cyd@gnu.org>
4350 * chartab.c (Fset_char_table_default): Obsolete function removed.
4352 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4354 Move pid_t related decls out of lisp.h.
4355 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4356 (interruptible_wait_for_termination):
4357 Move these decls from lisp.h to syswait.h, since they use pid_t.
4358 Needed on FreeBSD; see Herbert J. Skuhra in
4359 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4360 * callproc.c: Include syswait.h.

4378 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4379 * xfns.c (Fx_show_tip) [USE_GTK]:
4380 Use bool for boolean.
4381 * gtkutil.c (xg_update_frame_menubar):
4382 * xmenu.c (update_frame_menubar):
4383 Return void, not int, since caller ignores return value.

4387 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4389 * makefile.w32-in (BLOCKINPUT_H): Remove.

4406 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4408 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4409 fatal_error_backtrace.
4411 * w32proc.c (sys_kill): Undo last change: don't do anything when
4412 invoked to deliver SIGABRT to our own process. This is now
4413 handled by emacs_raise.
4415 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4417 * w32term.c (w32_read_socket): Remove leftover reference to
4418 interrupt_input_pending.
4420 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4422 Do not use SA_NODEFER.
4423 Problem reported by Dani Moncayo in
4424 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4426 * sysdep.c (emacs_abort): Do not reset signal handler.
4427 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4428 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4429 wanted even on POSIXish hosts, and it doesn't work on Windows.
4431 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4433 * xterm.c (x_term_init): Call fixup_locale before and after calling
4434 gtk_init (Bug#12392).
4436 2012-09-23 Chong Yidong <cyd@gnu.org>
4438 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4439 Vdynamic_library_alist.
4441 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4442 (Fgnutls_available_p): Caller changed.
4444 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4445 (Flibxml_parse_xml_region): Likewise.
4447 * dispextern.h (struct image_type): Remove arg from init function.
4449 * image.c (Finit_image_library, lookup_image_type)
4450 (define_image_type): Remove now-unneeded second arg.
4451 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4452 (init_tiff_functions, init_gif_functions, init_svg_functions):
4453 Arglist and w32_delayed_load calling convention changed.
4454 (gs_type): Remove init_gs_functions; there is no such function.
4455 (valid_image_p, make_image): Fix caller to lookup_image_type.
4457 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4459 Simplify and avoid signal-handling races (Bug#12471).
4461 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4462 Avoid recursive loop if there's a fatal error in the function itself.
4463 * atimer.c (pending_atimers):
4464 * blockinput.h: Don't include "atimer.h"; no longer needed.
4465 (interrupt_input_pending): Remove. All uses removed.
4466 pending_signals now counts both atimers and ordinary interrupts.
4467 This is less racy than having three separate pending-signal flags.
4468 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4470 Rename from their upper-case counterparts BLOCK_INPUT,
4471 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4472 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4473 This makes it easier to access volatile variables more accurately.
4474 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4475 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4476 that's more reliable if the code is buggy and sets
4477 interrupt_input_blocked to a negative value. All uses changed.
4478 * atimer.c (deliver_alarm_signal):
4479 Remove. No need to deliver this to the parent; any thread can
4480 handle this signal now. All uses replaced by underlying handler.
4481 * atimer.c (turn_on_atimers):
4482 * dispnew.c (handle_window_change_signal):
4483 * emacs.c (handle_danger_signal):
4484 * keyboard.c (kbd_buffer_get_event):
4485 Don't reestablish signal handler; not needed with sigaction.
4486 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4488 Rework to avoid unnecessary accesses to volatile variables.
4489 (UNBLOCK_INPUT_TO): Now a function.
4490 (totally_unblock_input, unblock_input): New decls.
4491 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4492 (init_data): Remove. Necessary stuff now done in init_signal.
4493 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4494 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4495 (fatal_error_code): Remove; no longer needed.
4496 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4497 it doesn't always backtrace. All uses changed. No need to reset
4498 signal to default, since sigaction and/or die does that for us now.
4499 Use emacs_raise (FOO), not kill (getpid (), FOO).
4500 (main): Check more-accurately whether we're dumping.
4501 Move fatal-error setup to sysdep.c
4502 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4503 * gtkutil.c (xg_get_file_name, xg_get_font):
4504 Remove no-longer-needed signal-mask manipulation.
4505 * keyboard.c, process.c (POLL_FOR_INPUT):
4506 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4507 * keyboard.c (read_avail_input): Remove.
4508 All uses replaced by gobble_input.
4509 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4510 (kbd_buffer_store_event_hold, gobble_input):
4511 (record_asynch_buffer_change) [USABLE_SIGIO]:
4512 (store_user_signal_events):
4513 No need to mess with signal mask.
4514 (gobble_input): If blocking input and there are terminals, simply
4515 set pending_signals to 1 and return. All hooks changed to not
4516 worry about whether input is blocked.
4517 (process_pending_signals): Clear pending_signals before processing
4518 them, in case a signal comes in while we're processing.
4519 By convention callers now test pending_signals before calling us.
4520 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4521 New functions, to support changes to blockinput.h.
4522 (handle_input_available_signal): Now extern.
4523 (reinvoke_input_signal): Remove. All uses replaced by
4525 (quit_count): Now volatile, since a signal handler uses it.
4526 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4527 All callers changed. Block SIGINT only if not already blocked.
4528 Clear sigmask reliably, even if Fsignal returns, which it can.
4529 Omit unnecessary accesses to volatile var.
4530 (quit_throw_to_read_char): No need to restore sigmask.
4531 * keyboard.c (gobble_input, handle_user_signal):
4532 * process.c (wait_reading_process_output):
4533 Call signal-handling code rather than killing ourselves.
4534 * lisp.h: Include <float.h>, for...
4535 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4536 (pending_signals): Now volatile.
4537 (syms_of_data): Now const if IEEE floating point.
4538 (handle_input_available_signal) [USABLE_SIGIO]:
4539 (terminate_due_to_signal, record_child_status_change): New decls.
4540 * process.c (create_process): Avoid disaster if memory is exhausted
4541 while we're processing a vfork, by tightening the critical section
4543 (send_process_frame, process_sent_to, handle_pipe_signal)
4544 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4546 (send_process): No need for setjmp/longjmp any more, since the
4547 SIGPIPE stuff is now gone. Instead, report an error if errno
4549 (record_child_status_change): Now extern. PID and W are now args.
4550 Return void, not bool. All callers changed.
4551 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4552 Remove. All uses removed. This bug should be fixed now in a
4554 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4555 and record the child status change directly. This avoids the
4556 need to futz with the signal mask.
4557 (process_fatal_action): Move here from emacs.c.
4558 (emacs_sigaction_flags): New function, containing
4559 much of what used to be in emacs_sigaction_init.
4560 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4561 caught by emacs, to make races less likely.
4562 (deliver_process_signal): Rename from handle_on_main_thread.
4564 (BACKTRACE_LIMIT_MAX): Now at top level.
4565 (thread_backtrace_buffer, threadback_backtrace_pointers):
4567 (deliver_thread_signal, deliver_fatal_thread_signal):
4568 New functions, for more-accurate delivery of thread-specific signals.
4569 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4570 (deliver_arith_signal): Handle in this thread, not
4571 in the main thread, since it's triggered by this thread.
4572 (maybe_fatal_sig): New function.
4573 (init_signals): New arg DUMPING so that we can be more accurate
4574 about whether we're dumping. Caller changed.
4575 Treat thread-specific signals differently from process-general signals.
4576 Block all signals while handling fatal error; that's safer.
4577 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4579 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4580 Ignore SIGPIPE unless batch.
4581 (emacs_backtrace): Output backtrace for the appropriate thread,
4582 which is not necessarily the main thread.
4583 * syssignal.h: Include <stdbool.h>.
4584 (emacs_raise): New macro.
4585 * xterm.c (x_connection_signal): Remove; no longer needed
4586 now that we use sigaction.
4587 (x_connection_closed): No need to mess with sigmask now.
4588 (x_initialize): No need to reset SIGPIPE handler here, since
4589 init_signals does this for us now.
4591 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4593 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4594 background rect may be larger (Bug#12245).
4596 2012-09-23 Chong Yidong <cyd@gnu.org>
4598 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4600 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4602 * .gdbinit: Just stop at fatal_error_backtrace.
4603 See Stefan Monnier's request in
4604 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4605 Remove no-longer-used query of system type.
4607 2012-09-22 Chong Yidong <cyd@gnu.org>
4609 * search.c (Freplace_match): Doc fix (Bug#12325).
4611 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4613 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4614 (Fline_end_position): Doc fix.
4616 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4618 2012-09-22 Chong Yidong <cyd@gnu.org>
4620 * dispextern.h (struct image_type): Add new slot, storing a type
4621 initialization function.
4623 * image.c (define_image_type): Call the image initializer function
4624 if it is defined. Arguments and return value changed.
4625 (valid_image_p, make_image): Callers changed.
4626 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4627 (gif_type, imagemagick_type, svg_type, gs_type):
4628 Add initialization functions.
4629 (Finit_image_library): Call lookup_image_type.
4630 (CHECK_LIB_AVAILABLE): Macro deleted.
4631 (lookup_image_type): Call define_image_type here, rather than via
4632 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4633 (syms_of_image): Move define_image_type calls for xbm_type and
4634 pbm_type to lookup_image_type.
4636 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4638 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4639 'idle_timers' from here ...
4640 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4641 lists, to avoid infloops when the timer does something stupid,
4642 like reinvoke itself with the same or smaller time-out.
4645 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4647 * window.c (Fsplit_window_internal): Handle only Qt value of
4648 Vwindow_combination_limit separately.
4649 (Qtemp_buffer_resize): New symbol.
4650 (Vwindow_combination_limit): New default value.
4653 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4655 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4656 the new overlay string. (Bug#10159)
4658 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4660 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4661 or that fprintf is async-signal-safe. POSIX doesn't require
4664 2012-09-22 Chong Yidong <cyd@gnu.org>
4666 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4669 2012-09-22 Kenichi Handa <handa@gnu.org>
4671 * composite.c (composition_reseat_it): Handle the case that a
4672 grapheme cluster is not covered by a single font (Bug#12352).
4674 2012-09-21 Chong Yidong <cyd@gnu.org>
4676 * image.c (define_image_type): Avoid adding duplicate types to
4677 image_types (Bug#12463). Suggested by Jörg Walter.
4679 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4681 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4682 (print_load_command_name): Add case LC_DATA_IN_CODE.
4683 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4685 2012-09-21 Glenn Morris <rgm@gnu.org>
4687 * eval.c (Frun_hook_with_args_until_success)
4688 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4690 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4692 * fileio.c (Ffile_selinux_context): Only call freecon when
4693 lgetfilecon succeeded.
4694 (Fset_file_selinux_context): Likewise. (Bug#12444)
4696 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4698 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4699 reordering, locate the cursor by calling set_cursor_from_row; if
4700 that fails, clear the desired glyph matrix before returning a
4701 failure indication to the caller. Fixes leaving garbled display
4702 when fast scrolling with a down-key. (Bug#12403)
4703 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4704 scrolling through multibyte text.
4706 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4708 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4709 calling mark_vectorlike since that's the one that marks the window.
4710 (mark_discard_killed_buffers): Mark the final cdr.
4711 * window.h (struct window): Move prev/next_buffers to the
4712 non-standard fields.
4713 * window.c (make_window): Initialize prev/next_buffers manually.
4715 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4717 Omit unused arg EXPECTED from socket hooks.
4718 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4719 * nsterm.m (ns_term_init):
4720 * termhooks.h (struct terminal.read_socket_hook):
4721 * w32inevt.c (w32_console_read_socket):
4722 * w32term.c (w32_read_socket):
4723 * xterm.c (XTread_socket):
4724 Omit unused arg EXPECTED. All callers changed.
4725 (store_user_signal_events): Return void, not int, since callers no
4726 longer care about the return value. All uses changed.
4728 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4730 * w32gui.h (XParseGeometry): Do not declare.
4732 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4734 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4735 Ignore 'expected'. See Eli Zaretskii in
4736 <http://bugs.gnu.org/12471#8> (last line).
4738 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4739 (XParseGeometry): Now static. Substitute extremal values for
4740 values that are out of range.
4742 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4744 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4746 * nsfns.m (XParseGeometry): Remove.
4747 (Fx_create_frame): Call x_set_offset to correctly interpret
4748 top_pos in geometry.
4750 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4751 (Fx_parse_geometry): If there is a space in string, call
4752 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4754 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4756 * search.c (scan_buffer): Use character positions in calls to
4757 region_cache_forward and region_cache_backward, not byte
4758 positions. (Bug#12196)
4760 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4761 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4763 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4764 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4765 emacs_blocked_malloc, now deleted.
4767 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4769 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4770 The workaround was for improving performance on Solaris 2.4, but
4771 is getting in the way now. Emacs will still work if someone is
4772 still running Solaris 2.4 in a museum somewhere; Sun dropped
4773 support for Solaris 2.4 in 2003.
4774 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4775 * process.c (create_process) [HAVE_WORKING_VFORK]:
4776 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4777 since Emacs no longer uses vfork on that platform.
4779 2012-09-17 Glenn Morris <rgm@gnu.org>
4781 * emacs.c: Use COPYRIGHT.
4783 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4785 Remove configure's --without-sync-input option (Bug#12450).
4786 When auditing signal-handling in preparation for cleaning it up,
4787 I found that SYNC_INPUT has race conditions and would be a real
4788 pain to fix. Since it's an undocumented and deprecated
4789 configure-time option, now seems like a good time to remove it.
4790 Also see <http://bugs.gnu.org/11080#16>.
4791 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4792 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4793 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4794 (malloc_hysteresis):
4795 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4796 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4797 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4798 (dont_register_blocks, bytes_used_when_reconsidered)
4799 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4800 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4801 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4802 Remove. All uses removed.
4803 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4804 implementation, one that depends on whether the new macro
4805 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4807 * atimer.c (run_timers, handle_alarm_signal):
4808 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4809 (handle_async_input, process_pending_signals)
4810 (handle_input_available_signal, init_keyboard):
4811 * nsterm.m (ns_read_socket):
4812 * process.c (wait_reading_process_output):
4813 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4814 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4816 * xterm.c (XTread_socket):
4818 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4819 * eval.c (handling_signal): Remove. All uses removed.
4820 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4821 All uses replaced with the SYNC_INPUT version.
4822 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4824 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4827 * font.c (Ffont_shape_gstring): Remove unused local.
4829 2012-09-16 Glenn Morris <rgm@gnu.org>
4831 * Makefile.in (clean): No longer run nextstep's clean.
4833 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4835 (ns-app): Move here from ns.mk, and simplify.
4836 (clean): Simplify nextstep entry.
4837 * ns.mk: Remove file.
4839 2012-09-17 Kenichi Handa <handa@gnu.org>
4841 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4842 not covert the last few charactes.
4844 2012-09-16 Kenichi Handa <handa@gnu.org>
4846 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4847 here, but just check the validity of glyphs in the glyph-string.
4849 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4851 * window.c (Fwindow_parameter, Fset_window_parameter):
4852 Accept any window as argument (Bug#12452).
4854 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4856 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4857 to ns_term_init to avoid memory leak.
4859 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4860 explicit retain/release.
4861 (ns_term_init): Only allow one display. Initialize outerpool and
4864 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4866 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4867 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4868 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4869 the Microsoft problem in a different way, by altering ../nt/config.nt.
4871 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4886 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4887 by lisp.h. This completes removal of setjmp.h inclusion
4888 erroneously announced in the previous commit. (Bug#12446)
4890 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4893 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4894 not defined as a macro. The latter happens on MS-Windows.
4897 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4899 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4900 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4901 Some instances of '#include <setjmp.h>' removed, if the
4902 only reason for the instance was because "lisp.h" was included.
4903 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4904 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4905 and _longjmp with the new symbols. Emacs already uses _setjmp if
4906 available, so this change affects only POSIXish hosts that have
4907 sigsetjmp but not _setjmp, such as some versions of Solaris and
4908 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4909 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4910 (png_load_body) [HAVE_PNG]:
4911 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4912 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4913 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4914 since PNG requires jmp_buf. This is the only exception to the
4915 general rule that we now use sys_setjmp and sys_longjmp.
4916 This exception is OK since this code does not change the signal
4917 mask or longjmp out of a signal handler.
4919 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4921 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4922 Include "syssignal.h", for 'main_thread'.
4924 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4926 Avoid out-of-range marker position (Bug#12426).
4927 * insdel.c (replace_range, replace_range_2):
4928 Adjust markers before overlays, as suggested by comments.
4929 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4930 Remove redundant check before calling offset_intervals.
4932 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4934 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4935 current buffer (Bug#12387).
4937 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4939 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4941 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4943 Use a more backwards-compatible timer format (Bug#12430).
4944 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4945 vector element, not from the 4th, since PSECS is now at the end.
4946 (Fcurrent_idle_time): Doc fix.
4948 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4950 Function to mark objects and remove killed buffers at once.
4951 * alloc.c (discard_killed_buffers): Rename to ...
4952 (mark_discard_killed buffers) ... new name. Add marking
4953 of remaining objects. Fix comment. Adjust users.
4954 (mark_object): Do not touch frame buffer lists here.
4955 * frame.c (delete_frame): Reset frame buffer lists here.
4957 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4959 Better workaround for GNOME bug when --enable-gcc-warnings.
4960 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4961 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4962 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4964 Simplify SIGIO usage (Bug#12408).
4965 The code that dealt with SIGIO was crufty and confusing, e.g., it
4966 played tricks like "#undef SIGIO" but these tricks were not used
4967 consistently. Simplify mostly by not #undeffing standard symbols,
4968 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4969 or not as we please) rather than "defined SIGIO" (standard symbol
4970 that we probably shouldn't #undef).
4971 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4972 Modules that need it can include it.
4973 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4974 * dispextern.h (ignore_sigio): New decl.
4975 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4976 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4977 * emacs.c (shut_down_emacs):
4978 * keyboard.c (kbd_buffer_store_event_hold):
4979 Use ignore_sigio rather than invoking 'signal' directly.
4980 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4982 (FIONREAD, SIGIO): Do not #undef.
4983 (tty_read_avail_input): Use #error rather than a syntax error.
4984 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4985 for I_PIPE, used by SETUP_SLAVE_PTY.
4986 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4987 * sysdep.c (croak): Remove; no longer needed. This bit of
4988 temporary code, with Fred N. Fish's comment that it's temporary,
4989 has been in Emacs since at least 1992!
4990 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4991 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4992 * syssignal.h (croak): Remove decl.
4993 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4994 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4995 now that we're termios-only.
4996 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4997 * term.c (dissociate_if_controlling_tty): Use #error rather than
5000 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5001 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5002 to work around GNOME bug 683906.
5003 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5004 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5005 This works around GCC bug 54561.
5007 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5009 More fixes for 'volatile' and setjmp/longjmp.
5010 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5011 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5012 (png_load_body) [HAVE_PNG]:
5013 (jpeg_load_body) [HAVE_JPEG]:
5014 New function, with most of the old parent function's body.
5015 (png_load) [HAVE_PNG]:
5016 (jpeg_load) [HAVE_JPEG]:
5017 Invoke the new function, to avoid longjmp munging our locals.
5018 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5019 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5020 longjmp is passed 2, as the C standard doesn't guarantee this.
5021 Instead, store the failure code into mgr->failure_code.
5023 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5025 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5026 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5027 (syms_of_keyboard): Remove support for unread-command-char.
5029 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5031 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5032 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5033 violation. (Bug#12426)
5035 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5037 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5039 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5041 * eval.c: Add `inhibit-debugger'.
5042 (Qinhibit_debugger): New symbol.
5043 (call_debugger): Bind it instead of Qdebug_on_error.
5044 (maybe_call_debugger): Test Vinhibit_debugger.
5045 (syms_of_eval): Define inhibit-debugger.
5046 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5047 (syms_of_xdisp): Remove inhibit-debug-on-message.
5049 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5051 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5052 If a nonvolatile local variable is written before a _longjmp to
5053 the frame containing the variable, and is read after the _longjmp,
5054 the value read is indeterminate. Some local variables of type
5055 'struct handler' and 'struct catchtag' are used in this way, so
5056 mark each of their slots as volatile if the slot can be set before
5057 _longjmp and read afterwards.
5058 * lisp.h (struct handler): var and chosen_clause are now volatile.
5059 (struct catchtag): val, next, and pdlcount are now volatile.
5061 * bidi.c (bidi_push_it, bidi_pop_it):
5062 * fns.c (copy_hash_table):
5063 * image.c (define_image_type):
5064 * keyboard.c (kbd_buffer_store_event_hold):
5065 * process.c (Fprocess_send_eof):
5066 * xfaces.c (x_create_gc) [HAVE_NS]:
5067 * xgselect.c (xg_select):
5068 Prefer assignment to memcpy when either will do.
5070 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5071 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5072 time an item is removed. No need to mark this function 'inline';
5073 the compiler knows better than we do.
5075 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5077 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5078 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5079 to change_frame_size (Bug#12388).
5080 (windowDidResize:): Pass YES to updateFrameSize.
5082 * nsterm.h: Add delay parameter to updateFrameSize.
5084 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5086 Discard killed buffers from deleted window and frame objects.
5087 This reduces an amount of references to killed buffers and
5088 helps GC to reclaim them faster.
5089 * alloc.c (discard_killed_buffers): New function.
5090 (mark_object): Use it for deleted windows and frames.
5091 (mark_object): If symbol's value is set up for a killed buffer
5092 or deleted frame, restore its global binding.
5093 * data.c (swap_in_global_binding): Add GC notice.
5094 (swap_in_symval_forwarding): Use convenient set_blv_where.
5095 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5096 * window.h: ... to here.
5098 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5100 Convenient macro to check whether the buffer is live.
5101 * buffer.h (BUFFER_LIVE_P): New macro.
5102 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5103 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5105 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5107 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5108 composition cases (Bug#12364).
5110 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5111 overhang of succeeding glyphs overlapping box cursor.
5113 * w32term.c (x_draw_glyph_string): Likewise.
5115 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5117 Simplify, document, and port floating-point (Bug#12381).
5118 The porting part of this patch fixes bugs on non-IEEE platforms
5119 with frexp, ldexp, logb.
5120 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5122 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5123 support, by removing commented-out code and briefly listing the
5124 C89 functions excluded. The commented-out stuff was confusing
5125 maintenance, e.g., we thought we needed cbrt but it was commented out.
5126 (logb): Remove decl; no longer needed.
5127 (isfinite): New macro, if not already supplied.
5128 (isnan): Don't replace any existing macro.
5129 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5130 are present on all C89 platforms.
5131 (Ffrexp): Do not special-case zero, as frexp does the right thing
5133 (Flogb): Do not use logb, as it doesn't have the desired meaning
5134 on hosts that use non-base-2 floating point. Instead, stick with
5135 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5136 frexp, to avoid getting an unspecified result.
5138 * xdisp.c (Qinhibit_debug_on_message): Now static.
5140 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5142 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5143 NSBezierPath (Bug#12131).
5145 2012-09-10 Chong Yidong <cyd@gnu.org>
5147 * fns.c (Fdelq, Fdelete): Doc fix.
5149 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5151 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5152 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5154 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5156 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5157 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5160 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5162 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5163 left fringe if the window has a left margin. This avoids leaving
5164 traces of the cursor because its leftmost pixel is not drawn over.
5166 * dispnew.c (update_window_line): When the left margin area of a
5167 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5168 that screen line. (Bug#12277)
5170 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5172 Assume C89 or later for math functions (Bug#12381).
5173 This simplifies the code, and makes it a bit smaller and faster,
5174 and (most important) makes it easier to clean up signal handling
5175 since we can stop worring about floating-point exceptions in
5176 library code. That was a problem before C89, but the problem
5177 went away many years ago on all practical Emacs targets.
5178 * data.c, image.c, lread.c, print.c:
5179 Don't include <math.h>; no longer needed.
5180 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5181 might be autoconfigured, as that never happens.
5183 * doprnt.c (DBL_MAX_10_EXP):
5184 * print.c (DBL_DIG):
5185 Remove. C89 or later always defines these.
5186 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5187 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5188 (arith_error, domain_error, domain_error2):
5189 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5190 no longer needed -- we simply return what C returns. All uses removed.
5191 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5193 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5194 Remove. All uses expanded, as these macros are no longer used
5195 more than once and are now more trouble than they're worth.
5196 (Ftan): Use tan, not sin / cos.
5197 (Flogb): Assume C89 frexp.
5198 (fmod_float): Assume C89 fmod.
5199 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5200 (init_floatfns): Remove. All uses removed.
5202 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5204 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5205 compositeToPoint for OSX < 10.6 (Bug#12390).
5207 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5209 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5210 This produces more-accurate results.
5212 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5214 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5215 changes (Bug#12088).
5217 2012-09-08 Chong Yidong <cyd@gnu.org>
5219 * syntax.c (Fstring_to_syntax): Doc fix.
5221 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5223 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5224 in the internal border.
5225 (x_set_window_size): Remove static variables and their usage.
5226 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5227 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5228 Remove fringe/internal border adjustment (Bug#11052).
5229 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5230 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5231 (ns_fix_rect_ibw): Remove.
5232 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5233 (ns_dumpglyphs_box_or_relief): Ditto.
5234 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5236 (ns_dumpglyphs_image): Ditto.
5237 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5239 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5240 their usage. Add fringe_extended_p and its use as in other terms.
5241 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5242 scroll bar was removed.
5243 (updateFrameSize): New function.
5244 (windowDidResize): Move code to updateFrameSize and call it.
5246 * nsterm.h (EmacsView): Add updateFrameSize.
5248 2012-09-07 Chong Yidong <cyd@gnu.org>
5250 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5252 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5254 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5256 More signal-handler cleanup (Bug#12327).
5257 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5258 Problem introduced when merging patches. Noted by Eli Zaretskii in
5259 <http://bugs.gnu.org/12327#67>.
5260 * floatfns.c: Comment fix.
5261 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5262 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5263 and anyway the declaration is harmless even if SIGDANGER is not defined.
5264 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5265 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5266 source files not surprisingly expected syssignal.h to define, or
5267 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5268 Include <sys/ioctl.h>, for FIONREAD.
5269 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5270 This eliminates a problem whereby other files mysteriously had
5271 to include "syssignal.h" before including "systty.h" if they
5272 wanted to use "#ifdef SIGIO".
5274 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5276 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5278 * w32.c (sigemptyset): Empty the set.
5279 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5281 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5283 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5285 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5286 (mark_object): Likewise for frame objects.
5288 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5290 * syssignal.h (handle_on_main_thread): Always declare,
5291 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5292 This ports to platforms without HAVE_PTHREAD.
5294 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5296 Signal-handler cleanup (Bug#12327).
5297 Emacs's signal handlers were written in the old 4.2BSD style with
5298 sigblock and sigmask and so forth, and this led to some
5299 inefficiencies and confusion. Rewrite these to use
5300 pthread_sigmask etc. without copying signal sets around. Also,
5301 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5302 'signal', and instead use functions that do not attempt to take
5303 over the system name space. This patch causes Emacs's text
5304 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5305 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5306 Do not include <signal.h> or "syssignal.h", as these
5307 modules do not use signals.
5308 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5309 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5310 Do not include <signal.h>, as "syssignal.h" does that for us now.
5311 * atimer.c (sigmask_atimers): New function.
5312 (block_atimers, unblock_atimers): New functions,
5313 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5315 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5316 no longer needed here.
5317 * emacs.c (main): Inspect existing signal handler with sigaction,
5318 so that there's no need to block and unblock SIGHUP.
5319 * sysdep.c (struct save_signal): New member 'action', replacing
5320 old member 'handler'.
5321 (save_signal_handlers, restore_signal_handlers):
5322 Use sigaction instead of 'signal' to save and restore.
5323 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5324 New function. All users of 'signal' modified to use set_sighandler
5325 if they're writeonly, and to use sys_signal if they're read+write.
5326 (emacs_sigaction_init, forwarded_signal): New functions.
5327 (sys_signal): Remove. All uses replaced by calls to sigaction
5328 and emacs_sigaction_init, or by direct calls to 'signal'.
5329 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5330 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5331 all uses replaced by pthread_sigmask etc. calls.
5332 * syssignal.h: Include <signal.h>.
5333 (emacs_sigaction_init, forwarded_signal): New decls.
5334 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5335 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5336 (sigmask, sys_sigmask): Remove; no longer needed.
5337 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5338 (sigblock, sigunblock, sigfree):
5339 (sigsetmask) [!defined sigsetmask]:
5340 Remove. All uses replaced by pthread_sigmask.
5341 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5342 no longer need to be replaced, and its typical old uses
5343 are now done via emacs_sigaction_init and sigaction.
5344 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5345 (sys_sigdel): Remove; unused.
5346 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5348 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5350 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5351 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5353 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5355 Explicitly mark buffer_defaults and buffer_local_symbols.
5356 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5357 mark_local_symbols here.
5358 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5359 since special buffers aren't marked here any more.
5360 (allocate_buffer): Chain new buffer with all_buffers here...
5361 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5363 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5364 (syms_of_buffer): Remove staticpro of the above.
5365 (init_buffer_once): Set names for buffer_defaults and
5366 buffer_local_symbols.
5368 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5370 Use bool for booleans in font-related modules.
5371 * font.c (font_intern_prop, font_style_to_value)

5373 (generate_otf_features, font_check_otf_features, font_check_otf)
5374 (font_match_p, font_list_entities, font_at):
5375 * fontset.c (fontset_id_valid_p, reorder_font_vector
5376 (fontset_find_font, Fset_fontset_font)
5377 (face_suitable_for_char_p) [0]:
5378 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5379 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5380 (m17n_flt_initialized, ftfont_shape_by_flt):
5381 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5382 * nsfont.m (nsfont_draw):
5383 * w32font.c (w32font_draw):
5384 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5385 Use bool for booleans.
5386 * font.h: Adjust to above API changes.
5387 (struct font, struct font_driver, struct font_driver_list):
5388 Use bool for booleans.
5389 (struct font): Remove useless member encoding_type.
5391 * fontset.c, xftfont.c: Omit unnecessary static decls.
5393 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5395 * alloc.c (mark_object): Revert window marking code
5396 since it's unsafe for the Fset_window_configuration.
5398 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5400 Fix race conditions with signal handlers and errno (Bug#12327).
5401 Be more systematic about preserving errno whenever a signal
5402 handler returns, even if it's not in the main thread. Do this by
5403 renaming signal handlers to distinguish between signal delivery
5404 and signal handling. All uses changed.
5405 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5406 * data.c (deliver_arith_signal): Rename from arith_error.
5407 * dispnew.c (deliver_window_change_signal): Rename from
5408 window_change_signal.
5409 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5410 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5411 * keyboard.c (deliver_input_available_signal): Rename from
5412 input_available_signal.
5413 (deliver_user_signal): Rename from handle_user_signal.
5414 (deliver_interrupt_signal): Rename from interrupt_signal.
5415 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5416 (deliver_child_signal): Rename from sigchld_handler.
5417 * atimer.c (handle_alarm_signal):
5418 * data.c (handle_arith_signal):
5419 * dispnew.c (handle_window_change_signal):
5420 * emacs.c (handle_fatal_signal, handle_danger_signal):
5421 * keyboard.c (handle_input_available_signal):
5422 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5423 * process.c (handle_pipe_signal, handle_child_signal):
5424 New functions, with the actual signal-handling code taken from the
5425 original respective signal handlers, sans the sporadic attempts to
5426 preserve errno, since that's now done by handle_on_main_thread.
5427 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5428 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5429 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5431 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5432 Move initialization of main_thread to sysdep.c's init_signals.
5433 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5434 our usage, and simplifies the mainline code.
5435 (record_child_status_change): New static function, as a helper
5436 for handle_child_signal, and with most of the old child handler's
5438 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5439 (handle_child_signal): Use the above.
5440 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5441 Moved here from emacs.c.
5442 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5443 code moved here from emacs.c's main function.
5444 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5445 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5446 This lets callers save and restore errno properly.
5448 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5450 Remove redundant or unused things here and there.
5451 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5452 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5453 * editfns.c (Fcompare_buffer_substrings): Likewise.
5454 * frame.h (struct terminal, struct font_driver_list):
5455 Remove redundant declarations.
5456 * window.h (Qleft, Qright): Likewise.
5458 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5460 Do not mark objects from deleted buffers, windows and frames.
5461 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5462 (mark_object): Likewise for windows and frames.
5464 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5466 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5467 buffer_defaults and buffer_local_symbols as valid objects.
5468 Return special value to denote them.
5470 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5472 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.

5474 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5475 (file_name_absolute_p, Fsubstitute_in_file_name):

5478 (Finsert_file_contents, choose_write_coding_system)
5479 (Fwrite_region, build_annotations, a_write, e_write)
5481 * filelock.c (boot_time_initialized, get_boot_time)
5482 (get_boot_time_1, lock_file_1, within_one_second):
5483 * floatfns.c (in_float):
5484 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5485 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5486 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5487 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5488 * window.c (compare_window_configurations):
5489 Use bool for booleans.
5490 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5491 (Fdefault_file_modes): Now mode_t, not int, for modes.
5492 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5493 (internal_delete_file): Now returns void, not a (boolean) int,
5494 since nobody was looking at the return value.
5495 * lisp.h, window.h: Adjust to above API changes.
5497 * xdisp.c (set_message): Simplify and reindent last change.
5499 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5501 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5503 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5505 * eval.c (call_debugger): Make the function non-static so that we
5506 can call it from set_message.
5508 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5509 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5511 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5513 Give more-useful info on a fatal error (Bug#12328).
5514 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5515 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5516 of doing the work ourselves.
5517 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5518 do most of the work.
5519 (fatal_error_backtrace): New function, taken from the guts
5520 of the old fatal_error_signal, but with a new option to output
5522 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5523 info about the signal than just its number.
5524 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5525 * sysdep.c: Include <execinfo.h>
5526 (emacs_backtrace): New function, taken partly from the previous
5527 code of the 'die' function.
5528 (emacs_abort): Call fatal_error_backtrace rather than abort.
5530 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5532 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5533 eager (load-time) macro-expansion.
5534 * lisp.mk (lisp): Add macroexp.
5536 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5538 Simplify redefinition of 'abort' (Bug#12316).
5539 Do not try to redefine the 'abort' function. Instead, redo
5540 the code so that it calls 'emacs_abort' rather than 'abort'.
5541 This removes the need for the NO_ABORT configure-time macro
5542 and makes it easier to change the abort code to do a backtrace.
5543 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5544 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5545 Remove; sysdep.c's emacs_abort now takes its place.
5546 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5547 'abort' changed to use 'emacs_abort'.
5548 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5549 (abort) [!defined abort]: Rename to ...
5550 (emacs_abort): ... new name.
5551 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5552 the place of the old 'abort' in emacs.c.
5553 * w32.c, w32fns.c (abort): Do not #undef.
5554 * w32.c (emacs_abort): Rename from w32_abort.
5556 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5558 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5559 offsets[j].dv, since the y axis of the screen coordinates points
5560 down, while the y axis of the font definition coordinates points
5561 up. This fixes display of Arabic diacritics such as KASRA and
5562 KASRATAN. (Bug#11860)
5564 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5566 Be more systematic about _setjmp vs setjmp.
5567 * alloc.c (test_setjmp, mark_stack):
5568 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5569 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5570 (png_load, my_error_exit, jpeg_load):
5571 * process.c (send_process_trap, send_process):
5572 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5573 The underscored versions are up to 30x faster on some hosts.
5574 Formerly, the code used setjmp+longjmp sometimes and
5575 _setjmp+_longjmp at other times, with no particular reason to
5576 prefer setjmp+longjmp.
5578 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5580 Fix minor problem found by static checking.
5581 * buffer.c (Fdelete_all_overlays): Return nil.
5583 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5585 * buffer.c (Fdelete_all_overlays): New function.
5587 2012-09-03 Chong Yidong <cyd@gnu.org>
5589 * gtkutil.c: Add extern decl for Qxft.
5591 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5593 * emacs.c, eval.c: Use bool for boolean.
5594 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

5605 All callers changed.
5606 * eval.c (interactive_p): Omit always-true boolean argument
5607 EXCLUDE_SUBRS_P. All callers changed.
5608 * dispextern.h, lisp.h: Reflect above API changes.
5609 * firstfile.c (dummy): Use the address of 'main', whose signature
5610 won't change, instead of the address of 'initialize', whose
5611 signature just changed from int to bool.
5612 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5613 * msdos.c (fatal_error_in_progress): ... from here.
5614 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5616 (redisplay_internal, unwind_redisplay): Simply clear
5617 REDISPLAYING_P when unwinding, instead of saving its previous,
5618 always-false value and then restoring it.
5620 Clean up some extern decls.
5621 Mostly, this hoists extern decls out of .c files and into .h files.
5622 That way, we're more likely to catch errors if the interfaces change.
5623 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5624 declare xg_mark_data.
5625 * dispextern.h (x_frame_parm_handlers):
5627 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5628 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

5643 * xfont.c (x_clear_errors):
5644 * xterm.c (x_frame_parm_handlers):
5645 Remove now-redundant extern decls.
5646 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5647 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5649 * xfaces.c: Remove unnecessary static decls.
5650 * xterm.c (updating_frame): Remove decl of nonexistent object.
5652 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5653 when building globals.h, as the objects that are not built on
5654 this host are not needed to compile C files on this host.
5656 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5658 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5686 * keyboard.c (decode_timer):
5687 Use bool for boolean.
5688 * intervals.h, lisp.h, systime.h: Reflect above API changes.

5696 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5698 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

5706 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5708 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5709 more than one grapheme cluster passed to the shaper: compute the
5710 offset adjustment values separately for each cluster. (Bug#11860)
5712 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5713 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5714 about implicit conversions from integer to pointer.
5716 2012-09-01 Daniel Colascione <dancol@dancol.org>
5718 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5719 system used too early.
5721 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5723 Better seed support for (random).

5752 * process.c: Include TERM_HEADER instead of listing all possible
5753 window-system headers.
5755 * nsterm.h: Remove declarations now in frame.h.
5756 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
5758 * menu.c: Include TERM_HEADER instead of listing all possible
5759 window-system headers.
5761 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
5764 * keyboard.c: Include TERM_HEADER instead of listing all possible
5765 window-system headers.
5767 * image.c: Include TERM_HEADER instead of listing all possible
5768 window-system headers. Declare Vlibrary_cache when compiling for
5771 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
5772 window system declarations.
5774 * frame.h: Move common functions here: set_frame_menubar,
5775 x_set_window_size, x_sync, x_get_focus_frame,
5776 x_set_mouse_position, x_set_mouse_pixel_position,
5777 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5801 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5803 Remove mark_ttys function and fix tty_display_info initialization.
5804 * lisp.h (mark_ttys): Remove prototype.
5805 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5806 to mark_ttys because all possible values of 'top_frame' slot are
5807 the frames which are reachable from Vframe_list.
5808 * term.c (mark_ttys): Remove.
5809 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5811 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5813 Change struct frame bitfields from unsigned char to unsigned.
5814 * frame.h (struct frame): Change type of 'display_preempted',

5816 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
5817 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
5818 bitfields from unsigned char to unsigned.

5831 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
5833 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
5834 for GCC 4.7.1 x86-64.
5836 2012-08-30 Glenn Morris <rgm@gnu.org>
5838 * lread.c (init_lread): For out-of-tree builds, only add the
5839 source directory's site-lisp dir to the load-path if it exists,
5840 consistent with in-tree builds. (Bug#12302)
5842 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5844 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

5853 (addString:row:): Remove return self, declare return value as void.
5854 (addSplit): Remove return self, declare return value as void.
5855 (clicked:): Remove return self, declare return value as void.
5856 Set dialog_return to button_values[seltag]. Code formatting change.
5857 (initFromContents:isQuestion:): Adjust call to process_dialog.
5858 Code formatting change.
5859 (timeout_handler:): Set timer_fired to YES.
5860 (runDialogAt:): Set timer_fired to NO.
5861 Handle click on close button as quit.
5863 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5864 Add window_closed and button_values. Add void as return value for
5865 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5866 Add process_dialog as new member.
5868 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5870 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
5871 is not one of the heaps we manage. (Bug#12242)

5932 Use bool for boolean.
5933 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
5934 and remove last int (actually boolean) argument, which was always 0.
5935 All callers changed.
5936 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
5937 * dispextern.h (struct composition_it): Use bool for boolean.
5938 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
5939 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
5940 * dired.c (file_name_completion):
5941 Use bool for boolean. (This was missed in an earlier change.)
5943 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5945 * window.c (Fset_window_configuration): Revert first part of
5948 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
5950 * nsterm.h (NSPanel): New class variable dialog_return.
5952 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
5953 Initialize dialog_return.
5954 (windowShouldClose:): Use stop instead of stopModalWithCode.
5955 (clicked:): Ditto, and also set dialog_return (Bug#12258).
5956 (timeout_handler:): Use stop instead of abortModal. Send a dummy
5958 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
5961 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
5963 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
5964 * composite.c (find_composition, composition_gstring_p)
5965 (composition_reseat_it, find_automatic_composition):

5971 * dbusbind.c (xd_in_read_queued_messages):
5972 * dired.c (directory_files_internal, file_name_completion):
5973 Use bool for booleans.
5974 * dired.c (file_name_completion):
5975 * process.h (fd_callback):
5976 Omit int (actually boolean) argument. It wasn't being used.
5978 * composite.h, lisp.h: Reflect above API changes.
5980 * cmds.c, coding.c: Use bool for booleans.
5981 * cmds.c (move_point, Fself_insert_command):

6001 (Fset_coding_system_priority):
6002 * fileio.c (Finsert_file_contents):
6003 Use bool for booleans.
6004 * coding.h, lisp.h: Reflect above API changes.
6005 * coding.c: Remove unnecessary static function decls.
6006 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6007 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6008 not a boolean 'int', since callers never look at the return value.
6009 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6010 * coding.h (decoding_buffer_size, encoding_buffer_size)
6011 (emacs_mule_string_char): Remove unused extern decls.
6012 (struct iso_2022_spec, struct coding_system):
6013 Use 'unsigned int : 1' for boolean fields, since there's more than one.
6014 (struct emacs_mule_spec): Remove unused field 'full_support'.
6015 All initializations removed.
6016 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6018 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6020 Fix spare memory change (Bug#12286).
6021 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6022 (valid_lisp_object_p): Likewise.
6024 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6026 * window.c (Fset_window_configuration): Record any window's old
6027 buffer if it's replaced (see Bug#8789). If the new current
6028 buffer doesn't appear in the selected window, go to its old
6031 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6033 Special MEM_TYPE_SPARE to denote reserved memory.
6034 * alloc.c (enum mem_type): New memory type.
6035 (refill_memory_reserve): Use new type for spare memory.
6036 This prevents live_cons_p and live_string_p from incorrect
6037 detection of uninitialized objects from spare memory as live.
6039 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6042 * Makefile.in (.PHONY): versioclean -> versionclean.
6044 Remove unused external symbols.
6045 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6046 * window.c (Qwindow_valid_p, decode_valid_window):
6047 Now static, not extern.
6048 * data.c (Qinterval): Remove; unused.
6049 (syms_of_data): Do not define 'interval'.
6050 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6051 * window.h (decode_valid_window):
6054 * character.c, charset.c, chartab.c: Use bool for booleans.
6055 * character.c (lisp_string_width, string_count_byte8)
6056 (string_escape_byte8):
6057 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6058 (load_charset_map_from_file, map_charset_chars)
6059 (Fdefine_charset_internal, define_charset_internal)
6060 (Fdeclare_equiv_charset, find_charsets_in_text)
6061 (Ffind_charset_region, char_charset, Fiso_charset):

6063 (sub_char_table_set, sub_char_table_set_range)
6064 (char_table_set_range, optimize_sub_char_table)
6065 (map_sub_char_table):
6066 Use bool for boolean.
6067 * character.c (str_to_unibyte): Omit last boolean argument; it was
6068 always 0. All callers changed.
6069 * character.h, charset.h: Adjust to match previous changes.
6070 * character.h (char_printable_p): Remove decl of nonexistent function.
6071 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6072 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6073 are all boolean, so make them single-bit bitfields.
6075 * lisp.h (ASET): Remove attempt to detect side effects.
6076 It was meant to be temporary and it often doesn't work,
6077 because when IDX has side effects the behavior of IDX==IDX
6078 is undefined. See Stefan Monnier in
6079 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6081 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6083 * lisp.h (functionp): New function (extracted from Ffunctionp).
6084 (FUNCTIONP): Use it.
6085 * eval.c (Ffunctionp): Use it.
6087 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6089 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6090 as that's faster and simpler than static storage. Don't bother
6091 with the g_main_context_query overhead if g_main_context_pending
6092 says no events are pending.
6093 (gfds, gfds_size): Remove these static vars.
6094 (xgselect_initialize): Remove; no longer needed.
6095 All uses and decls removed.
6097 * emacs.c (fatal_error_signal_hook): Remove.
6098 All uses removed. This leftover from old code was always 0.
6100 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6101 * casefiddle.c (casify_object, casify_region):
6102 * casetab.c (set_case_table):
6103 * category.c, category.h (word_boundary_p):
6104 * category.h (CHAR_HAS_CATEGORY):
6105 Use bool for booleans, instead of int.
6107 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6109 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6111 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6113 On assertion failure, print backtrace if available.
6114 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6115 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6116 * Makefile.in (LIB_EXECINFO): New macro.
6119 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6120 * bytecode.c (exec_byte_code):
6121 * callint.c (check_mark, Fcall_interactively):
6122 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6123 (getenv_internal, sync_process_alive, call_process_exited):
6124 * lisp.h (USE_SAFE_ALLOCA):
6125 Use bool for booleans, instead of int.
6126 * lisp.h, process.h: Adjust prototypes to match above changes.
6127 * callint.c (Fcall_interactively): Don't assume the mark's
6128 offset fits in 'int'.
6130 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6132 * buffer.c, buffer.h: Use bool for boolean.
6133 * buffer.c (reset_buffer_local_variables)
6134 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6135 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6136 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6137 (overlay_touches_p, overlay_strings, Foverlay_put)
6138 (report_overlay_modification, call_overlay_mod_hooks):
6139 (mmap_enlarge, mmap_set_vars):
6140 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6141 Use bool for booleans, instead of int.
6142 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6143 since the 1-or-0 return value is always ignored anyway.
6144 (mmap_initialized_p):
6145 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6146 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6148 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6150 * bidi.c: Use bool for boolean.
6151 This is a bit more readable, and makes the text segment of bidi.o
6152 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6153 Presumably it's faster too.
6154 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6156 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6157 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6158 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6159 (bidi_explicit_dir_char, bidi_level_of_next_char)
6160 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6161 Use bool for booleans, instead of int.
6162 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6163 (bidi_unshelve_cache): Adjust decls to match code.
6165 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6167 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6170 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6172 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6173 * atimer.h: Include <stdbool.h>.
6175 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6177 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6178 compile time tests instead of run time tests on systems that do
6180 (FRAME_MAC_P): Remove leftover from deleted code.
6181 * frame.c (syms_of_frame): Remove leftover from deleted code.
6183 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6185 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6187 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6189 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6190 Otherwise, the compiler complains about (A?B:C) where B is void
6191 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6192 (fontset_add): Return void, for FONTSET_ADD.
6194 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6196 * alloc.c: Use bool for booleans.
6197 (gc_in_progress, abort_on_gc)
6198 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6199 (dont_register_blocks) [GC_MALLOC_CHECK]:
6200 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6201 (check_string_bytes, make_specified_string, memory_full)
6202 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6203 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6204 (mark_stack, valid_pointer_p, make_pure_string)
6205 (Fgarbage_collect, survives_gc_p, gc_sweep):
6206 Use bool for booleans, instead of int.
6207 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6208 Remove unused local.
6209 * alloc.c (PURE_POINTER_P):
6210 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6211 * editfns.c (Fformat):
6212 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6214 * fns.c (sweep_weak_table):
6215 * lisp.h (suppress_checking, push_message, survives_gc_p)
6216 (make_pure_string, gc_in_progress, abort_on_gc):
6217 * lread.c (readchar, read1):
6218 * print.c (Fprin1_to_string):
6219 * xdisp.c (push_message):
6220 Use bool for booleans affected directly or indirectly by
6223 Make recently-introduced setters macros.
6224 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6225 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6226 (set_fontset_default, set_fontset_fallback): Rename from their
6227 upper-case counterparts, and make them functions rather than macros.
6228 This is more consistent with the other recently-introduced setters.
6229 These don't need to be inline, since they're local.
6231 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6233 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6234 the loop (Bug#12247).
6236 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6238 * lisp.h (vcopy): Use memcpy rather than our own loop.
6239 This fixes a performance regression introduced by the recent
6240 addition of vcopy. This means 'vcopy' will need to be modified
6241 for a copying collector, but that's OK. Also, tighten the
6242 checking in the assertion.
6244 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6246 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6247 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6248 non-base glyph for the width of the base character, according to
6249 what x_draw_composite_glyph_string_foreground expects.
6250 Generate WADJUST value according to composition_gstring_width's
6251 expectations, to produce correct width of the composed character.
6252 Reverse the sign of the DU offset produced by ScriptPlace.
6254 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6256 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6258 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6260 Avoid direct writes to contents member of struct Lisp_Vector.
6261 * lisp.h (vcopy): New function to copy data into vector.
6262 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6263 * fns.c (Ffillarray): Use ASET.
6264 * keyboard.c (timer_check_2): Use AREF and ASET.
6265 (append_tool_bar_item, Frecent_keys): Use vcopy.
6266 * lread.c (read_vector): Use ASET.
6267 * msdos.c (Frecent_doskeys): Use vcopy.
6268 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6269 (Finternal_merge_in_global_face): Use ASET and vcopy.
6270 * xfont.c (xfont_list_pattern): Likewise.
6272 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6274 * window.c (Fwindow_point): For the selected window always return
6275 the position of its buffer's point.
6276 (Fset_window_point): For the selected window always go in its
6277 buffer to the specified position.
6279 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6281 Setter macros for fontsets.
6282 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6283 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6284 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6287 2012-08-20 Glenn Morris <rgm@gnu.org>
6289 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6290 Don't assume that `ln -f' works.
6292 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6294 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6295 and later about non-assignments with no effect. See discussion at
6296 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6299 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6301 Inline setter functions for Lisp_Objects slots of struct specbinding.
6302 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6305 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6307 * window.c (select_window): Always make selected window's buffer
6310 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6312 Use AREF and ASET for docstrings of category tables.
6313 * category.h (CATEGORY_DOCSTRING): Use AREF.
6314 (SET_CATEGORY_DOCSTRING): Use ASET.
6315 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6317 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6319 Inline setter functions for hash table members.
6320 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6321 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6322 (set_hash_key_and_value, set_hash_index, set_hash_next)
6323 (set_hash_hash): New functions.
6324 * charset.c, fns.c: Adjust users.
6326 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6328 Inline getter and setter functions for per-buffer values.
6329 * buffer.h (per_buffer_default, set_per_buffer_default)
6330 (per_buffer_value, set_per_buffer_value): New functions.
6331 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6332 * buffer.c, data.c: Adjust users.
6334 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6336 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6338 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6340 Rely on <config.h> + <unistd.h> to declare 'environ',
6341 as gnulib does this if the system doesn't.
6342 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6343 Remove declaration. MS-Windows declares it on stdlib.h which is
6344 included by conf_post.h.
6345 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6346 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6347 * vm-limit.c: Include <unistd.h>, for 'environ'.
6349 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6350 (start_of_data): Remove decl; mem-limits.h provides it.
6352 * xdisp.c (handle_invisible_prop): Make it a bit faster
6353 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6355 2012-08-19 Chong Yidong <cyd@gnu.org>
6357 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6360 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6362 * .gdbinit: Use call instead of set when calling a function in the
6365 * data.c (set_internal): Don't use set_blv_found.
6366 (Fkill_local_variable): Likewise.
6368 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6370 * nsfont.m (ns_ascii_average_width): Ensure the string
6371 ascii_printable is initialized with a null-terminated character
6372 array. Otherwise, it can contain undesired extra characters.
6374 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6376 port new setting code to Sun C 5.8 2005/10/13
6377 * chartab.c, lisp.h (char_table_set, char_table_set_range):

6766 Use bool, not int, for Lisp booleans.

7245 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
7247 Export DEFAULT_REHASH_* to GDB.
7248 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
7249 Now constants, not macros.
7251 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
7253 Remove unnecessary casts involving pointers.
7254 These casts are no longer needed now that we assume C89 or later,
7255 since they involve casting to or from void *.
7256 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
7257 (make_pure_float, make_pure_vector):
7258 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

7266 * xselect.c (x_stop_queuing_selection_requests)
7267 (x_get_window_property, x_get_window_property_as_lisp_data):
7268 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7269 Remove unnecessary pointer casts.
7270 * alloc.c (record_xmalloc): New function.
7271 * lisp.h (record_xmalloc): New decl.
7272 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7273 more like a function. This is because the pointer cast is not
7274 needed. All uses changed.
7275 * print.c (print_string, print_error_message): Avoid length recalc.
7277 Improve fix for macroexp crash with debugging (Bug#12118).
7278 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7279 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7280 not supposed to be invoked from the garbage collector.
7281 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7282 (gc_aset): New function, which is like ASET but can be
7283 used in the garbage collector.
7284 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
7285 (set_hash_index): Use it instead of ASET.

7296 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
7297 (map_w32_filename): Improve commentary. Simplify switch.
7298 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
7299 headers (most versions of MinGW w32api don't).
7300 (get_security_info, create_symbolic_link)
7301 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
7303 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
7304 in the argument file name.

7307 (sys_rename): Diagnose renaming of a symlink when the user doesn't
7308 have the required privileges.
7309 (get_file_security_desc_by_name): Rename from
7310 get_file_security_desc.
7311 (stat_worker): New function, with most of the guts of 'stat', and
7312 with addition of handling of symlinks and support for 'lstat'.
7313 If possible, get file's attributes and security information by
7314 handle, not by name. Produce S_IFLNK bit for symlinks, when
7315 called from 'lstat'.
7316 (stat, lstat): New functions, call 'stat_worker'.
7317 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7318 symlinks when the underlying filesystem supports them.
7320 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7322 Fix macroexp crash on Windows with debugging (Bug#12118).
7323 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7324 checking subscripts; problem introduced with the recent
7325 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7326 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7327 since it's used in non-static inline functions now.
7329 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7330 Don't assume buffer size fits in 'int'. Remove unused local.

7342 * buffer.h, category.h, character.h, charset.h, composite.h:
7343 * dispextern.h, lisp.h, systime.h:
7344 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
7345 * alloc.c (LISP_INLINE):
7346 * buffer.c (BUFFER_INLINE):
7347 * category.c (CATEGORY_INLINE):
7348 * character.c (CHARACTER_INLINE):
7349 * charset.c (CHARSET_INLINE):
7350 * composite.c (COMPOSITE_INLINE):
7351 * dispnew.c (DISPEXTERN_INLINE):
7352 * sysdep.c (SYSTIME_INLINE):
7353 Define to EXTERN_INLINE, so that the corresponding functions
7354 are compiled into code.
7355 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7356 (INLINE_HEADER_END): New macros.
7357 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7377 hard-coding the path separator.
7379 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7381 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7382 This how ASET and AREF are supposed to work, and makes
7383 it easier to think about future improvements. See
7384 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7385 * charset.h (set_charset_attr): New function.
7386 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
7387 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

7800 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7801 enumeration constants, as PURE and HEAP are too general, and clash
7802 with other headers and sources, such as gmalloc.c and the
7803 MS-Windows system headers. All users changed.
7805 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7807 Revert last save_excursion_save and save_excursion_restore changes.
7808 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7821 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7822 arms of an 'if', not using conditional expressions; otherwise GDB
7823 complains about the types in the unevaluated arm when the argument
7824 is an integer literal.
7825 (xgetint): Simplify expression.
7826 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7827 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7828 Zaretskii in <http://bugs.gnu.org/12036#13>.
7829 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7830 needed now that we have gdb_make_enums_visible.
7831 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7832 (enum enum_USE_LSB_TAG):
7833 New enum types, packaging up enums that need to be exported to GDB.

7875 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7876 emacs.c, as this is a more-suitable home. Had this been done earlier
7877 the fix for 12036 would have avoided some of the problems noted in
7878 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7879 would have been more obvious.
7880 * emacs.c: Do not include <verify.h>; no longer needed.
7881 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

7889 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7890 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7891 not be usable in #if. This simplifies things.
7893 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7895 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7900 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7901 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7902 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7903 Adjust to changes in lisp.h and emacs.c, by using
7904 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7905 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7906 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7907 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7908 instead of gdb_valbits.
7909 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7910 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7911 instead of gdb_array_mark_flag.
7912 (xboolvector): Get size from $->size, not $->header.size.
7913 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7914 (xreload, hook-run, hookpost-run): Remove.
7915 * emacs.c: Include <verify.h>.
7916 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7917 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7919 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7920 (gdb_USE_LSB_TAG): New enum constants.
7921 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7922 Also define these as enum constants, so they're visible to GDB.
7923 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7924 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7925 as constants, so they're visible to GDB.

7928 Now enum constants, not macros, so they're visible to GDB.
7929 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7930 more convenient now. All uses changed.
7931 (VALMASK) [USE_LSB_TAG]: Also define in this case.

7941 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7942 add argument, tune behavior, and adjust all callers.
7944 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7946 Use typedef for EMACS_INT, EMACS_UINT.
7947 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7948 than macros. This simplifies debugging in the usual case, since
7949 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7950 and it allows expressions involving EMACS_INT casts.
7951 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7953 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7965 Adjust buffer text indirection counters at the end of Fkill_buffer.
7966 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7967 buffer is definitely dead. This should really fix an issue reported
7968 by Christoph Scholtes again. (Bug#12007).
7969 (init_buffer_once): Initialize indirection counters of
7970 buffer_defaults and buffer_local_symbols (for sanity and safety).
7972 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7974 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7975 and continuation glyphs on tooltip frames, leave them at zero.

8003 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8005 Swap buffer text indirection counters in Fbuffer_swap_text.
8006 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8007 This avoids crash reported by Christoph Scholtes at
8008 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8010 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8012 * nsmenu.m (Popdown_data): New struct.
8013 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8015 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
8016 (initWithContentRect): Make imgView and contentView non-static
8017 and autorelease them. Also autorelease img and matrix (Bug#12005).
8018 (dealloc): Remove (Bug#12005).
8020 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8022 Adjust consing_since_gc when objects are explicitly freed.

8035 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8037 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8038 as it's limited by the amount of memory, not by INT_MAX.
8040 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8042 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8043 in special-event-map. See the discussion at

8102 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8103 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8104 Adjust users accordingly.

8766 * s/aix4-2.h (unix): Remove; no longer needed.
8768 EMACS_TIME simplification (Bug#11875).
8769 This replaces macros (which typically do not work in GDB)

8771 The functional style also makes code easier to read and maintain.
8772 * systime.h: Include <sys/time.h> on all hosts, not just if
8773 WINDOWSNT, since 'struct timeval' is needed in general.

8789 (add_emacs_time, sub_emacs_time): New functions.
8790 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

8813 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8814 Prefer snprintf to strncpy.
8815 * nsterm.m (ns_term_init):
8816 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8817 * nsterm.m (ns_term_init):
8818 Avoid the need for strncpy, by using build_string or
8819 make_unibyte_string directly. Use dtoastr, not snprintf.
8820 * process.c (Fmake_network_process): Diagnose service names that
8821 are too long, rather than silently truncating them or creating
8822 non-null-terminated names.

8839 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8840 where argument type is known to be a Lisp_Cons.

8895 O_RDONLY already includes it).
8897 Stop ns builds setting the EMACSLOADPATH environment variable.
8898 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8899 Now it does not set EMACSLOADPATH, just returns the load-path string.

8901 * lread.c [HAVE_NS]: Include nsterm.h.
8902 (init_lread) [HAVE_NS]: Use ns_load_path.

8972 Move marker debugging code under MARKER_DEBUG.
8973 * marker.c (MARKER_DEBUG): Move marker debugging code under
8974 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8975 for bootstrap with --enable-checking (~3x slowdown reported

9027 2012-07-07 Glenn Morris <rgm@gnu.org>
9029 * lread.c (load_path_check): New function, split from init_lread.
9030 (init_lread): Reorganize. Motivation:
9031 If EMACSLOADPATH is set, check/warn about that rather than the
9032 defaults, which we are not going to use. Hence we can remove
9033 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9034 Don't warn if site-lisp directories are missing.
9035 If not installed, start from a blank load-path, since
9036 PATH_LOADSEARCH refers to the eventual installation directories.
9038 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9040 Support truncation and continuation glyphs on GUI frames, when
9041 fringes are disabled. (Bug#11832)
9042 * xdisp.c (init_iterator): Get dimensions of truncation and
9043 continuation glyphs even if on GUI frames.
9044 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9045 or both, are absent.
9046 (start_display, move_it_in_display_line_to): Handle the case of a
9047 GUI frame without a fringe to display continuation or truncation
9049 (insert_left_trunc_glyphs): Support GUI frames: make sure
9050 truncation glyphs overwrite enough glyphs from the current line to
9051 have sufficient space in pixels.
9052 (display_line): Support truncation and continuation glyphs on GUI
9053 frames. If some spare pixels are left on the line after inserting
9054 the truncation glyphs, fill that space with a stretch glyph of a
9055 suitably computed width.
9057 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9058 produce_glyphs, to support GUI sessions.
9060 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9062 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9064 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9066 Do not require float-time's arg to fit in time_t (Bug#11825).
9067 This works better on hosts where time_t is unsigned, and where
9068 float-time is applied to the (negative) difference between two times.
9069 * editfns.c (decode_time_components): Last arg is now double *,
9070 not int *, and means to store all the result as a double, without
9071 worrying about whether the seconds part fits in time_t.
9072 All callers changed.
9073 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9074 All callers changed.
9075 (Ffloat_time): Do not fail merely because the specified time falls
9076 outside of time_t range.
9078 2012-07-07 Glenn Morris <rgm@gnu.org>
9080 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9087 Update dependencies.
9089 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9091 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9093 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9094 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9095 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9096 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9097 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9098 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9100 * xfont.c (compare_font_names): Redo to omit the need for casts.
9102 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9104 * xfns.c (Fx_change_window_property): Doc fix.
9105 * w32fns.c (Fx_change_window_property): Doc fix.
9107 * w32fns.c (Fx_window_property): Accept the same arguments as the
9108 X Windows version. Doc fix.
9109 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9111 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9112 Eli Zaretskii <eliz@gnu.org>
9114 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9115 Windows-specific code from nt/config.nt moved here.
9116 Obsolete settings removed.
9118 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9120 * process.c: Avoid unnecessary calls to gettime.
9121 (wait_reading_process_output): Don't get the time of day
9122 when gobbling data immediately and not waiting, as there's no need
9123 for it in that case. This removes a FIXME.
9125 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9127 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9128 is defined (Bug#11768).
9130 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9132 Fix marker debugging code.
9133 * marker.c (byte_char_debug_check): Do not perform the check
9134 if buffer is not multibyte.
9135 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9136 Call byte_char_debug_check with correct arguments.
9138 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9140 Compile marker debugging code only if ENABLE_CHECKING is defined.
9141 * marker.c (byte_char_debug_check, count_markers):
9142 Use only if ENABLE_CHECKING is defined.
9143 (byte_debug_flag): Remove.
9144 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9145 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9147 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9149 Avoid code repetition in marker-related functions.
9150 * marker.c (attach_marker): New function.
9151 (Fset_marker, set_marker_restricted, set_marker_both)
9152 (set_marker_restricted_both): Use it.
9153 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9154 Consistently rename charno to charpos.
9155 (marker_position): Add eassert.
9156 (marker_byte_position): Convert to eassert.
9158 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9160 Simplify list operations in unchain_overlay and unchain_marker.

9162 * marker.c (unchain_marker): Simplify. Fix comments.
9164 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9166 Introduce fast path for the widely used marker operation.
9167 * alloc.c (build_marker): New function.
9168 * lisp.h (build_marker): New prototype.
9169 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9170 * composite.c (autocmp_chars): Likewise.
9171 * editfns.c (buildmark): Remove.
9172 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9173 (save_restriction_save): Use build_marker.
9174 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9175 * window.c (save_window_save): Likewise.
9177 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9179 Do not use Fdelete_overlay in delete_all_overlays
9180 to avoid redundant calls to unchain_overlay.
9181 * buffer.c (drop_overlay): New function.
9182 (delete_all_overlays, Fdelete_overlay): Use it.
9183 * minibuf.c (get_minibuffer): Fix comment.
9185 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9187 Port to OpenBSD 5.1 amd64.
9188 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9189 This is needed for OpenBSD, and should be harmless on all BSD systems.
9190 Also, include <sys/sysctl.h>, as it should be available on all
9191 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9192 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9193 use p_pid member, not kp_proc.pid.
9195 2012-07-06 Glenn Morris <rgm@gnu.org>
9197 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9199 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9201 More xmalloc and related cleanup.
9202 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
9203 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
9204 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

9208 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
9209 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9210 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9212 Omit needless casts involving void * pointers and allocation.
9213 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9214 as the former is more robust if P's type is changed.
9215 Prefer xzalloc to xmalloc + memset 0.
9216 Simplify malloc-or-realloc to realloc.
9217 Don't worry about xmalloc returning a null pointer.
9218 Prefer xstrdup to xmalloc + strcpy.
9219 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9221 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9222 alloca of a constant.
9224 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9226 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9227 hscroll is larger than the line width. Fixes long and futile
9228 looping inside extend_face_to_end_of_line (on a TTY) producing
9229 glyphs that are not needed and thrown away.
9231 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9233 * marker.c (set_marker_restricted_both): Simplify by using
9236 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9238 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9240 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

9243 not defined (Bug#11768).
9244 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9245 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9246 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9247 followed by gtk_box_set_homogeneous (Bug#11768).
9248 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9249 (update_theme_scrollbar_width, xg_create_scroll_bar):
9250 Use gtk_scrollbar_new (Bug#11768).
9251 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9252 (is_box_type): New function (Bug#11768).
9253 (xg_tool_item_stale_p): Call is_box_type.
9254 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9255 with default display (Bug#11768).
9257 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9259 * xdisp.c (window_hscroll_limited): New function.
9260 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9261 coordinates when window's hscroll is set to insanely large
9264 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9266 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9267 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
9269 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

9325 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9327 * fileio.c (time_error_value): Check the right error number.
9328 Problem reported by Troels Nielsen in
9329 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9331 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9333 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9334 This should be fixed in a better way; see Eli Zaretskii in
9335 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9336 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9338 * fileio.c (time_error_value): Rename from special_mtime.
9339 The old name's problems were noted by Eli Zaretskii in
9340 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9342 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9343 This variable's comment says Emacs needs at least one GDB-visible
9344 symbol of type enum pvec_type, to work around GDB problems.
9345 The symbol's value doesn't matter.
9347 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9348 that causes compilation to fail on pre-C99 compilers.
9350 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9352 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9353 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9355 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9357 * buffer.c (init_buffer_once): Fix initialization of
9358 headers for buffer_defaults and buffer_local_symbols.
9359 Reported by Juanma Barranquero <lekktu@gmail.com>.
9361 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9363 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9364 * lisp.h (enum pvec_type): Use fewer bits.
9365 (PSEUDOVECTOR_SIZE_BITS): New constant.
9366 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9367 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9368 change in pvec_type.
9369 (PSEUDOVECTOR_TYPEP): New macro.
9370 (TYPED_PSEUDOVECTORP): Use it.
9371 * fns.c (internal_equal): Adapt code to extract pvectype.
9372 * emacs.c (gdb_pvec_type): Update type.
9373 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9374 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9375 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9376 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9377 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9378 abusing vector->header.next.nbytes.
9379 (live_vector_p): Use PVEC_TYPE.
9380 (mark_object): Adapt code to extract pvectype. Use switch.
9382 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9384 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9385 Tighten new eassert a bit.
9387 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9389 Fix compilation with --enable-gcc-warnings and -O1
9391 * doprnt.c (doprnt): Change type of tem to int, initialize
9392 to avoid compiler warning. Add eassert.
9393 * search.c (simple_search): Initialize match_byte to avoid
9394 compiler warning. Add eassert.
9396 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9398 Avoid weird behavior with large horizontal scrolls.
9399 Without this change, for example, large hscroll values would
9400 mess up Emacs's display on Fedora 15 x86, presumably due to
9401 overflows in int calculations in the display code.
9402 Also, if buffers had long lines, Emacs would freeze.
9403 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9404 (set_window_hscroll): New function, containing the old guts of
9405 Fset_window_hscroll. Return the clipped value.
9406 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9407 This avoids the need to check against PTRDIFF_MAX.
9409 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9411 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9413 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9415 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9417 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9418 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9419 since GCC 4.4.6 issues a bogus warning for them.
9421 Fix bugs in file timestamp newness comparisons.
9422 * fileio.c (Ffile_newer_than_file_p):
9423 * lread.c (Fload): Use full timestamp resolution of files,
9424 not just the 1-second resolution, so that files that are only
9425 slightly newer still count as newer.
9426 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9427 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9429 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9431 * fileio.c: Improve handling of file time marker. (Bug#11852)
9432 (special_mtime): New function.
9433 (Finsert_file_contents, Fverify_visited_file_modtime):
9434 Use it to set special mtime values consistently.
9436 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9438 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9439 marker for non-existing file. (Bug#11852)
9441 2012-07-03 Glenn Morris <rgm@gnu.org>
9443 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9444 and did not make it into globals.h).
9446 2012-07-03 Tom Tromey <tromey@redhat.com>

9486 * lisp.h (Frandom): Make it visible to C.
9487 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9488 buffer for invisible buffers. (Bug#1229)
9490 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9492 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9493 values which aren't power of 2.
9494 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9495 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9498 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9500 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9502 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9504 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9506 * alloc.c (allocate_vector_block): Remove redundant
9507 calls to mallopt if DOUG_LEA_MALLOC is defined.
9508 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9509 avoid calls to mallopt if zero_vector is returned.
9511 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9513 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9514 is enabled, avoid dereferencing NULL current_sblock if
9517 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9519 Cleanup basic buffer management.
9520 * buffer.h (struct buffer): Change layout to use generic vector
9521 marking code. Fix some comments. Change type of 'clip_changed'
9522 to bitfield. Remove unused #ifndef old.
9523 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9524 (GET_OVERLAYS_AT): Fix indentation.
9525 (for_each_per_buffer_object_at): New macro.
9526 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

9529 * alloc.c (allocate_buffer): Adjust to match new layout of
9530 struct buffer. Fix comment.
9531 (mark_overlay): New function.
9532 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9533 Lisp area of struct buffer.
9534 (mark_object): Use it. Adjust marking of misc objects
9535 and related comments.
9537 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9539 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9540 wrapper that is not needed because the wrapped code is a no-op (zero
9541 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9542 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9544 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9546 * alloc.c (mark_buffer): Simplify. Remove prototype.
9547 (mark_object): Add comment. Reorganize marking of vector-like
9548 objects. Use CHECK_LIVE for all vector-like objects except buffers
9549 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9550 Avoid redundant calls to mark_vectorlike for bool vectors.
9552 2012-06-30 Glenn Morris <rgm@gnu.org>
9554 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9556 * epaths.in (PATH_SITELOADSEARCH): New.
9557 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9558 This is rather than relying on --enable-locallisppath elements
9559 having "site-lisp" in their names. (Bug#10208#25, 11658)
9561 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9563 * w32proc.c (sys_select): Accept and ignore one more argument.
9565 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9567 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9568 (pselect) [!MS_DOS]: Redirect to sys_select.
9570 * sysdep.c: Don't include dos.h and dosfns.h.
9572 * process.c (sys_select):
9573 * msdos.c (sys_select): Accept one more argument and ignore it.
9575 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9576 adapt data types and code to that.
9579 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9580 which clashes with the gnulib function of the same name.
9582 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9584 * font.c (font_style_to_value, font_style_symbolic)
9585 (font_prop_validate_style): Add type checks for values in
9588 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9590 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9593 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9595 * xdisp.c (try_window_id): Undo last change.
9597 * w32.c (getwd): Adjust commentary about startup_dir.
9598 (init_environment): Always call sys_access, even in non-MSVC
9599 builds. Don't chdir to the directory of the Emacs executable.
9600 This undoes code from 1997 which was justified by the need to
9601 "avoid conflicts when removing and renaming directories". But its
9602 downside was that every relative file name was being interpreted
9603 relative to the directory of the Emacs executable, which can never
9604 be TRT. In particular, it broke sys_access when called with
9605 relative file names.
9606 (sys_access): Map GetLastError to errno.
9608 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9610 * window.h (struct window): Change type of 'fringes_outside_margins'

9620 Add QUIT to make the loop interruptible.
9622 2012-06-29 Glenn Morris <rgm@gnu.org>
9624 * charset.c (init_charset): Make lack of etc/charsets fatal.
9626 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9628 * editfns.c (region_limit): Fix type mismatch.
9630 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9632 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9633 undefined. Convert from xassert to eassert.
9634 * nsmenu.m: Convert from xassert to eassert.
9635 * nsterm.m: Likewise.
9637 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9639 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9641 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9643 Avoid integer overflow on scroll-left and scroll-right.
9644 * window.c (HSCROLL_MAX): New macro.
9645 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9646 overflow when requested scroll falls outside ptrdiff_t range.

9650 * window.h (struct window): Change type of 'hscroll',
9651 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9652 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9653 Adjust users accordingly.
9654 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9655 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9656 from EMACS_INT to ptrdiff_t.
9657 (make_window): Omit redundant initialization.
9659 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9663 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9665 * window.h (struct window): Change type of 'use_time' and
9666 'sequence_number' from Lisp_Object to int.

9732 * alloc.c (allocate_string): Omit intervals initialization.
9733 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9734 as in make_pure_string and make_pure_c_string.

9792 a better opportunity to optimize away calls to strlen when the
9793 function is called with compile-time constant argument.

9795 * w32proc.c (sys_spawnve): Likewise.

9798 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9800 Use sprintf return value instead of invoking strlen on result.
9801 In the old days this wasn't portable, since some sprintf
9802 implementations returned char *. But they died out years ago and
9803 Emacs already assumes sprintf returns int.
9804 Similarly for float_to_string.
9805 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

9812 * xfns.c (syms_of_xfns):
9813 Use sprintf or float_to_string result to avoid need to call strlen.
9814 * data.c (Fnumber_to_string):
9815 Use make_unibyte_string, since the string must be ASCII.
9816 * lisp.h, print.c (float_to_string): Now returns int length.
9817 * term.c (produce_glyphless_glyph):
9818 Use sprintf result rather than recomputing it.
9820 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

9853 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

9856 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9858 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9859 instead of truncating it to 63 (admittedly a generous limit).
9861 * process.c: Fix spelling and caps in comments.
9863 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9865 * emacs.c (setpgrp): Remove definition, unused.

9919 * keyboard.c (kbd_buffer_get_event):
9920 * process.c (Faccept_process_output):

9989 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9991 Support higher-resolution time stamps (Bug#9000).
9992 The time stamps are only nanosecond-resolution at the C level,
9993 since that's the best that any real-world system supports now.
9994 But they are picosecond-resolution at the Lisp level, as that's
9995 easy, and leaves room for future OS improvements.
9997 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10000 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10001 Don't get current time unless it's needed.
10003 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10004 now provides it if it's absent.
10005 (start_atimer): Port to higher-res time stamps.
10006 Check for time stamp overflow. Don't get current time more
10007 often than is needed.
10009 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10010 Include systime.h, not time.h.
10011 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10013 * dired.c: Include stat-time.h.
10014 (Ffile-attributes): File times now have higher resolution.
10016 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10017 (struct image): Timestamp now has higher resolution.
10019 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10020 has at least microseconds now. All uses removed.
10021 (update_frame, update_single_window, update_window, update_frame_1)
10022 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10023 (duration_to_sec_usec): Remove; no longer needed.
10025 * editfns.c (time_overflow): Now extern.
10026 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10027 (float-time, Fformat_time_string, Fcurrent_time_string)

10031 (decode_time_components, lisp_seconds_argument): New functions.
10032 (make_time): Now static.
10033 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10034 Report an error if the time is invalid, rather than having the caller
10037 * fileio.c: Include <stat-time.h>
10038 (Fcopy_file): Copy higher-resolution time stamps.
10039 Prefer to set the time stamp via a file descriptor if that works.
10040 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10041 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10042 (Fvisited_file_modtime, Fset_visited_file_modtime):
10043 Support higher-resolution time stamps.
10045 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10047 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10049 * image.c (prepare_image_for_display, clear_image_cache)
10050 (lookup_image): Port to higer-resolution time stamps.
10052 * keyboard.c (start_polling, bind_polling_period):
10053 Check for time stamp overflow.
10054 (read_char, kbd_buffer_get_event, timer_start_idle)
10055 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10056 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10057 Port to higher-resolution time stamps. Do not assume time_t is signed.
10058 (decode_timer): New function. Timers are now vectors of length 9,
10059 not 8, to accommodate the picosecond component.
10060 (timer_check_2): Use it.
10062 * nsterm.m (select_timeout, timeval_subtract): Remove.
10063 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10064 as they're a bit more accurate and handle overflow better.
10065 (ns_select): Change prototype to be compatible with pselect.
10066 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10067 * nsterm.h (ns_select): Adjust prototype.
10069 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10070 us-resolution time stamps.
10071 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10073 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10075 * lisp.h (time_overflow): New decl.
10076 (wait_reading_process_output): First arg is now intmax_t, not int,
10077 to accommodate larger waits.
10079 * process.h (struct Lisp_Process.read_output_delay):
10080 Now counts nanoseconds, not microseconds.
10081 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10083 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10084 (wait_reading_process_output):
10085 Port to ns-resolution time stamps.
10086 (Faccept_process_output, wait_reading_process_output):
10087 Check for time stamp overflow. Do not assume time_t is signed.
10088 (select_wrapper): Remove; we now use pselect.
10089 (Fprocess_attributes): Now generates ns-resolution time stamps.
10091 * sysdep.c: Include utimens.h. Don't include utime.h
10092 or worry about struct utimbuf; gnulib does that for us now.
10093 (gettimeofday): Remove; gnulib provides a substitute.
10094 (make_timeval): New function.
10095 (set_file_times): Now sets ns-resolution time stamps.
10096 New arg FD; all uses changed.
10097 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10098 (system_process_attributes):
10099 Now returns ns-resolution time stamp. All uses changed.
10100 Check for time stamp overflow.
10102 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10103 provides a substitute now.
10105 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10106 since it guarantees struct timespec.
10107 (EMACS_TIME): Now struct timespec, so that we can support
10108 ns-resolution time stamps.
10109 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10110 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10111 (EMACS_USECS): Remove.
10112 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10113 so multiply the arg by 1000 before storing it.
10114 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10116 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10117 Port to ns-resolution time stamps.
10118 (EMACS_TIME_NEG_P): Remove; replaced by....

10123 (make_timeval, make_lisp_time, decode_time_components): New decls.
10124 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10125 that it mishandled time_t overflow. You can't compare by subtracting!
10126 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10127 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10129 * term.c: Include <sys/time.h>.
10130 (timeval_to_Time): New function, for proper overflow wraparound.
10131 (term_mouse_position, term_mouse_click): Use it.
10133 * undo.c (record_first_change): Support higher-resolution time stamps
10134 in the undo buffer.
10135 (Fprimitive_undo): Use them when restoring time stamps.
10137 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10138 (w32_get_internal_run_time):
10139 Port to higher-resolution Emacs time stamps.
10140 (ltime): Now accepts single 64-bit integer, as that's more convenient
10143 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10145 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10146 for compatibility with pselect. Support ns-resolution time stamps.
10148 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10150 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10151 Check for time stamp overflow, and support ns-resolution time stamps.
10153 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10154 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10155 (timeval_subtract): Remove; no longer needed.
10156 (XTflash, XTring_bell, x_wait_for_event):
10157 Port to ns-resolution time stamps. Don't assume time_t is signed.

10163 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10165 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10166 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10167 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10168 staticidx goes up to 1597 out of 1600 = 0x640.)
10170 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10172 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

10184 access to `contents' member of Lisp_Vector objects with AREF and ASET
10187 2012-06-19 Chong Yidong <cyd@gnu.org>
10189 * frame.c (delete_frame): When selecting a frame on a different
10190 text terminal, do not alter the terminal's top-frame.

10193 frame's selected window and its terminal's top-frame.
10194 (unwind_format_mode_line): Restore them.
10195 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10197 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

10199 (prepare_menu_bars): Likewise.
10201 * term.c (Ftty_top_frame): New function.
10203 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

10206 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10207 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10208 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10209 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

10216 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10218 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10219 gets killed during executing of this function (Bug#11665).
10220 Try to always return Qt when the buffer has been actually killed.
10221 (Vkill_buffer_query_functions): In doc-string say that functions
10222 run by this hook should not change the current buffer.
10224 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10226 Fix recently-introduced process.c problems found by static checking.
10227 * process.c (write_queue_push, write_queue_pop, send_process):

10246 * lisp.h (eassert): Assume C89 or later.
10247 This removes the need for CHECK.
10248 (CHECK): Remove. Its comments about always evaluating its
10249 argument were confusing, as 'eassert' typically does not evaluate
10252 * coding.c (produce_chars): Use ptrdiff_t, not int.
10254 * xterm.c (x_draw_underwave): Check for integer overflow.
10255 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10431 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
10432 (roundup_size): Verify that it is a power of 2.
10433 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
10434 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
10435 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
10436 -DUSE_LSB_TAG=0, to override the automatically-selected default.
10437 USE_LSB_TAG now is always defined to be either 0 or 1.
10439 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
10440 code works fine either way, and efficiency is not a concern here,
10441 as the union type is for debugging, not for production.
10442 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10443 Use an inline function on all platforms when using the union type,
10444 since this is simpler and 'static inline' can be used portably
10446 (LISP_INITIALLY_ZERO): New macro.
10447 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
10448 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
10450 2012-06-12 Glenn Morris <rgm@gnu.org>

10470 * image.c (imagemagick_load_image): Remove unused label.
10472 2012-06-11 Glenn Morris <rgm@gnu.org>

10475 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
10476 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
10477 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
10479 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
10481 * alloc.c (make_byte_code): New function.

10512 tty_alt_charset_p. Add tty_italic_p.
10514 2012-06-09 Michael Albinus <michael.albinus@gmx.de>
10516 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
10517 dbus_type_is_basic if available.
10518 (xd_extract_signed, xd_extract_unsigned): Rename from
10519 extract_signed and extract_unsigned, respectively. Adapt callers.

10530 * xdisp.c (vmessage): Treat frame message as multibyte.
10531 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
10532 would generate the diagnostic "Making \302\247 buffer-local while
10535 2012-06-08 Eli Zaretskii <eliz@gnu.org>
10537 * dispnew.c (showing_window_margins_p): Undo last change, which
10538 was done due to an inadvertent commit.
10539 (adjust_frame_glyphs_for_frame_redisplay): Do call
10540 showing_window_margins_p.

10548 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
10550 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
10551 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
10553 2012-06-08 Eli Zaretskii <eliz@gnu.org>
10555 * alloc.c (allocate_vectorlike): Fix last change.
10557 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
10559 Block-based vector allocation of small vectors.
10560 * lisp.h (struct vectorlike_header): New field `nbytes',
10561 adjust comment accordingly.
10562 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10563 to denote vector blocks. Adjust users (live_vector_p,
10564 mark_maybe_pointer, valid_lisp_object_p) accordingly.

10586 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10588 * doprnt.c (doprnt): Truncate multibyte char correctly.
10589 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10590 would mishandle a string argument "Xc" if X was a multibyte
10591 character of length 2: it would truncate after X's first byte
10592 rather than including all of X.
10594 2012-06-06 Chong Yidong <cyd@gnu.org>
10596 * buffer.c (word_wrap): Doc fix.
10598 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

10624 position is past the end of the mode line string.
10626 * buffer.c (buffer_local_value_1): New function, split from
10627 Fbuffer_local_value; can return Qunbound.
10628 (Fbuffer_local_value): Use it.
10629 (Vmode_line_format): Docstring tweaks.
10631 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

10643 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10645 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10646 Convert pctcpu and pctmem to Lisp float properly.
10647 Let the compiler fold better, as 100.0/0x8000 is exact.
10649 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10651 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10654 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

10658 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10660 For a 'struct window', replace some Lisp_Object fields to
10661 bitfields where appropriate, remove unused fields.
10662 * window.h (struct window): Remove unused 'last_mark_x' and
10663 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10664 change its type from Lisp_Object to bitfield.
10665 Change type of 'force_start', 'optional_new_start',
10666 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10667 fields from Lisp_Object to bitfield. Adjust users accordingly.
10669 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10671 Pacify gcc -Wdouble-precision when using Xaw.
10672 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10673 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10674 Use 'float' consistently, rather than 'float' in most places
10675 and 'double' in a couple of places.
10677 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10679 * xdisp.c (handle_stop): Detect whether we have overlay strings
10680 loaded by testing it->current.overlay_string_index to be
10681 non-negative, instead of checking whether n_overlay_strings is
10682 positive. (Bug#11587)
10684 2012-05-31 Chong Yidong <cyd@gnu.org>
10686 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10688 * doc.c (Fsubstitute_command_keys): Doc fix.
10690 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10692 * search.c (search_buffer): Remove calls to
10693 r_alloc_inhibit_buffer_relocation, as it is now called by
10694 maybe_unify_char, which was the cause of relocation of buffer text
10697 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10699 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10700 for the duration of call to load_charset, to avoid problems with
10701 callers of maybe_unify_char that access buffer text through C
10704 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10705 decrement the inhibition flag, instead of just setting or
10708 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10710 Remove obsolete '#define static' cruft.
10711 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10712 This #undef was "temporary" in 2000; it is no longer needed
10713 now that '#define static' has gone away.
10714 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10715 (gray_bitmap_bits): Remove; no longer needed.
10716 All uses replaced with definiens.
10717 * xterm.c: Include "bitmaps/gray.xbm".
10719 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

10722 The following changes affect the code only when profiling.
10723 * dispnew.c (__executable_start): Rename from safe_bcopy.
10724 Define only on platforms that need it.
10725 * emacs.c: Include <sys/gmon.h> when profiling.
10726 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10727 (__executable_start): Remove decl, since lisp.h does it now.
10728 (safe_bcopy): Remove decl; no longer has that name.
10729 (main): Coalesce #if into single bit of code, for simplicity.
10730 Cast pointers to uintptr_t, since standard libraries want integers
10732 * lisp.h (__executable_start): New decl.
10734 2012-05-31 Glenn Morris <rgm@gnu.org>
10736 * image.c (Fimagemagick_types): Doc fix.

10757 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10759 Do not create empty overlays with the evaporate property (Bug#9642).
10760 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10761 Bug#9642, but explicitly check that the buffer the overlay would
10762 be moved to is live and rearrange lines to make sure that errors
10763 will not put the overlay in an inconsistent state.
10764 (Fdelete_overlay): Cosmetics.
10766 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10768 * w32term.c (my_bring_window_to_top): New function.
10769 (x_raise_frame): Use handle returned by DeferWindowPos, which
10770 could be different from the original one.

10780 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10782 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10783 This avoids undefined behavior that might cause the eassert
10784 to not catch an out-of-range value.
10786 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10788 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

10800 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10802 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10803 Only r_alloc_inhibit_buffer_relocation needed to be added;
10804 the others were already declared.
10806 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10807 before checking whether it's out of range. Put the check inside
10809 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10811 2012-05-27 Ken Brown <kbrown@cornell.edu>
10813 * callproc.c (Fcall_process): Restore a line that was accidentally
10814 commented out in the 2011-02-13 change (bug#11547).

10818 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10819 defined on ralloc.c.
10821 * buffer.c [REL_ALLOC]: Remove prototypes of
10822 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10823 they are now on lisp.h.
10825 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10827 * search.c (search_buffer): Use it to inhibit relocation of buffer
10828 text while re_search_2 is doing its job, because re_search_2 is
10829 passed C pointers to buffer text. (Bug#11519)
10831 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10832 Update value to 24.
10834 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10835 state after an additional call to move_it_in_display_line_to, keep
10836 the values of it->max_ascent and it->max_descent found for the
10838 (pos_visible_p): Revert the comparison against bottom_y to what it
10839 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10842 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10844 Fix coding-related core dumps with gcc -ftrapv.
10845 The code was computing A - B, where A and B are pointers, and B is
10846 random garbage. This can lead to core dumps on platforms that
10847 have special pointer registers, and it also leads to core dumps on
10848 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10849 A - B only when B is initialized properly.
10850 * coding.c (coding_set_source, coding_set_destination): Return void.
10851 (coding_change_source, coding_change_destinations): New functions,
10852 with the old behaviors of coding_set_source and coding_set_destination.
10853 All callers that need an offset changed to use these new functions.
10855 2012-05-26 Glenn Morris <rgm@gnu.org>
10857 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

10862 * xdisp.c (draw_row_with_mouse_face):
10863 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10865 * w32console.c: Include window.h.
10866 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10868 (initialize_w32_display): Initialize mouse-highlight data.
10870 * w32inevt.c: Include termchar.h and window.h.
10871 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10872 moves, call note_mouse_highlight. If help_echo changed, call
10873 gen_help_event to produce help-echo message in the echo area.
10874 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10877 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10879 * lread.c (read1): Simplify slightly to avoid an overflow warning
10880 with GCC 4.7.0 on x86-64.
10882 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10884 * bidi.c (bidi_mirror_char): Revert last change: an int is
10885 definitely wide enough here.
10887 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10889 Fix integer width and related bugs (Bug#9874).

10923 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10924 (validate_region): Omit unnecessary test for b <= e,
10925 since that's guaranteed by the previous test.
10926 (adjust_overlays_for_delete): Avoid pos + length overflow.
10927 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10928 (report_overlay_modification):

10930 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10931 Omit pointer cast, which isn't needed anyway, and doesn't work
10932 after the EMACS_INT -> ptrdiff_t change.
10933 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10934 * buffer.h: Adjust decls to match defn changes elsewhere.

10939 not int, to avoid needless 32-bit limit on 64-bit hosts.
10940 (exec_byte_code): Use tighter memory-full test, one that checks
10941 for alloca overflow. Don't compute the address of the object just
10942 before an array, as that's not portable. Use EMACS_INT, not
10943 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10944 * callint.c (Fcall_interactively):
10945 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

10958 (casify_object): Avoid integer overflow when overallocating buffer.
10959 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

10962 * category.h (CATEGORYP): Don't assume arg is nonnegative.

10969 Check that Vcode_version_map_vector is a vector.
10970 (resolve_symbol_ccl_program): Check that vector header is in range.
10971 Always copy the vector, so that we can check its contents reliably
10972 now rather than having to recheck each instruction as it's being
10973 executed. Check that vector words fit in 'int'.
10974 (ccl_get_compiled_code, Fregister_ccl_program)
10975 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10976 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

10981 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

11001 (Fdefine_charset_internal): Check ranges here, more carefully.
11002 Don't rely on undefined behavior with signed left shift overflow.
11003 Don't assume unsigned int fits into fixnum, or that fixnum fits
11004 into unsigned int. Don't require max_code to be a valid fixnum;
11005 that's not true for gb10830 4-byte on a 32-bit host. Allow
11006 invalid_code to be a cons, for the same reason. Require code_offset
11007 to be a character. Avoid int overflow if max_char is close
11009 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11010 this is intended anyway and avoids some undefined behavior.
11011 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11012 INDEX_TO_CODE_POINT, as that's what it expects.
11013 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11014 * charset.h (DECODE_CHAR): Return int, not unsigned;
11015 this is what was intended anyway, and it avoids undefined behavior.
11016 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11017 integer-overflow issues.
11018 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11019 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11020 where the argument is EMACS_INT, and this behavior is not intended.
11021 * chartab.c (Fmake_char_table, Fset_char_table_range)
11022 (uniprop_get_decoder, uniprop_get_encoder):
11023 Don't assume fixnum fits in int.
11024 * cmds.c (move_point): New function, that does the gist of
11025 Fforward_char and Fbackward_char, but does so while checking
11026 for integer overflow more accurately.
11027 (Fforward_char, Fbackward_char): Use it.
11028 (Fforward_line, Fend_of_line, internal_self_insert)

11677 * xterm.c (x_x_to_emacs_modifiers):
11678 Don't assume EMACS_INT overflows nicely into int.
11679 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
11680 may come from Lisp.
11681 (handle_one_xevent): NATNUMP can eval its arg twice.
11682 (x_connection_closed):
11683 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

11697 (unreadpure): Remove function.
11698 (readevalloop): Don't call read_list with -1 flag.

11711 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11713 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11716 This directory predates autoconf and is no longer needed nowadays.
11717 Move its few remaining bits of functionality to where they're needed.
11718 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

11721 * Makefile.in (M_FILE): Remove. All uses removed.
11722 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
11723 * lisp.h (USE_LSB_TAG):
11724 * mem-limits.h (EXCEEDS_LISP_PTR):
11725 Use VAL_MAX, not VALBITS, in #if.
11726 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.

11728 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11729 (BITS_PER_EMACS_INT): New constants, replacing
11730 what used to be in config.h, but not useful in #if.
11731 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11732 define them any more.
11733 (VAL_MAX): New macro.
11735 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11736 BITS_PER_EMACS_INT, in #if.
11737 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11738 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11739 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:

11741 Move here from removed file m/intel386.h.
11742 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11743 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11745 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11747 Assume C89 or later.
11748 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

11772 * xfns.c (x_in_use): Remove `static' qualifier.
11773 * xterm.h (x_in_use): Declare.
11774 * xgselect.c: Include xterm.h.
11775 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11776 and `display_arg' (bug#9754).
11778 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>

11799 (Fword_search_forward, Fword_search_backward_lax)
11800 (Fword_search_forward_lax): Move functions to isearch.el
11801 (bug#10145, bug#11381).
11803 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11805 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11807 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11809 * lread.c (init_obarray): Declare Qt and Qnil as special.
11811 2012-05-14 Glenn Morris <rgm@gnu.org>
11813 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11814 Put "libexec" before "bin", for the sake of init_callproc_1.
11816 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11818 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11820 * unexaix.c: Port to more-recent AIX compilers.
11821 (report_error, report_error_1, make_hdr, copy_sym)
11822 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11823 Make arguments const char *, not char *, to avoid violations of C
11824 standard and to fix some AIX warnings reported by Gilles Pion.
11826 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11828 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11829 already have overlays loaded.
11830 (handle_single_display_spec): Before returning without displaying
11831 fringe bitmap, synchronize the bidi iterator with the main display
11832 iterator, by calling iterate_out_of_display_property.
11833 (iterate_out_of_display_property): Detect buffer iteration by
11834 testing that it->string is a Lisp string.
11835 (get_next_display_element): When the current object is exhausted,
11836 and there's something on it->stack, call set_iterator_to_next to
11837 proceed with what's on the stack, instead of returning zero.
11838 (set_iterator_to_next): If called at the end of a Lisp string,
11839 proceed to consider_string_end without incrementing string
11840 position. Don't increment display vector index past the end of
11841 the display vector. (Bug#11417)
11842 (pos_visible_p): Don't report a position visible when move_it_to
11843 stopped at the last line of window, which happens to be scanned
11844 backwards by the bidi iteration. (Bug#11464)
11846 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11848 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11849 and right-margin display specs even if the spec is invalid or we
11850 are on a TTY, and thus unable to display on the fringes.
11851 That's because the text with the property will not be displayed anyway,
11852 so we need to signal to the caller that this is a "replacing"
11853 display spec. This fixes display when the spec is invalid or we
11856 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11858 * unexaix.c (make_hdr): Fix typo in prototype.
11859 This bug broke the build on AIX. Problem reported by Gilles Pion.
11861 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11863 * keyboard.c (kbd_buffer_get_event): Read special events also in
11864 batch mode. (Bug#11415)
11866 2012-05-12 Glenn Morris <rgm@gnu.org>

11870 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11872 * lisp.mk (lisp): Add newcomment.elc.
11874 2012-05-12 Glenn Morris <rgm@gnu.org>
11876 * Makefile.in (MKDIR_P): New, set by configure.
11877 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11879 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11881 Remove unused function hourglass_started.
11882 * dispextern.h (hourglass_started):
11883 * w32fns.c (hourglass_started):

11888 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11889 Update dependencies.
11891 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11893 * xgselect.c (xg_select): Put maxfds+1 into a var.
11894 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11896 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11898 2012-05-10 Dave Abrahams <dave@boostpro.com>
11900 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11901 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11903 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11905 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11906 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11907 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11908 Initialize xd_registered_buses.
11910 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11912 Untag more efficiently if USE_LSB_TAG.
11913 This is based on a proposal by YAMAMOTO Mitsuharu in
11914 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11915 For an admittedly artificial (nth 8000 longlist) benchmark on
11916 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11917 Emacs's overall text size by 1%.
11918 * lisp.h (XUNTAG): New macro.
11919 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11920 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11921 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11922 * eval.c (Fautoload):
11923 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11924 * frame.h (XFRAME): Use XUNTAG.
11926 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11927 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11928 Remove unportable assumptions about print widths of types like
11930 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11931 intptr_t when converting between pointer and integer, to avoid GCC
11932 warnings about wrong width.
11934 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11936 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11937 stack for each reader_thread, instead of defaulting to 8MB
11938 determined by the linker. This avoids failures in creating
11939 subprocesses on Windows 7, see the discussion in this thread:
11940 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11942 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11944 Fix up display of the *Minibuf-0* buffer in the mini window.
11945 * keyboard.c (read_char): Don't clear the echo area if there's no
11947 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11948 contents of *Minibuf-0*) if there's no message displayed in its stead.
11950 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11952 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11955 2012-05-06 Chong Yidong <cyd@gnu.org>
11957 * lisp.mk (lisp): Update.
11959 2012-05-05 Jim Meyering <meyering@redhat.com>
11961 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11963 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11965 * data.c (PUT_ERROR): New macro.
11966 (syms_of_data): Use it. Add new error type `user-error'.
11967 * undo.c (user_error): New function.
11968 (Fprimitive_undo): Use it.
11969 * print.c (print_error_message): Adjust print style for `user-error'.
11970 * keyboard.c (user_error): New function.
11971 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11973 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11975 Do not limit current-time-string to years 1000..9999.
11976 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11977 (Fcurrent_time_string): Support any year that is supported by the
11978 underlying localtime representation. Don't use asctime, as it
11979 has undefined behavior for years outside the range -999..9999.
11981 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11983 Fix race conditions involving setenv, gmtime, localtime, asctime.
11984 Without this fix, interrupts could mess up code that uses these
11985 nonreentrant functions, since setting TZ invalidates existing
11986 tm_zone or tzname values, and since most of these functions return
11987 pointers to static storage.
11988 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11989 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11990 Grow the critical sections to include not just invoking
11991 localtime/gmtime, but also accessing these functions' results
11992 including their tm_zone values if any, and any related TZ setting.
11993 (format_time_string): Last arg is now struct tm *, not struct tm **,
11994 so that the struct tm is saved in the critical section.
11995 All callers changed. Simplify allocation of initial buffer, partly
11996 motivated by the fact that memory allocation needs to be outside
11997 the critical section.
11999 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12001 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12002 with RESET_INTERVAL.
12004 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12005 Remove duplicated buffer name initialization.
12007 2012-05-02 Jim Meyering <jim@meyering.net>
12009 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12011 * xfns.c (x_window): Use xstrdup (Bug#11375).
12013 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12015 * xdisp.c (pos_visible_p): If already at a newline from the
12016 display string before the 'while' loop, don't walk back the glyphs
12017 from it3.glyph_row. Solves assertion violation when the display
12018 string begins with a newline (egg.el). (Bug#11367)
12020 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12022 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12025 2012-05-01 Glenn Morris <rgm@gnu.org>
12027 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12028 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12029 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12030 All were removed before 23.1.
12032 * dispnew.c: Remove HAVE_LIBNCURSES test;
12033 it is always true on relevant platforms.
12035 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12036 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12038 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12040 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12042 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12043 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12046 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12048 Do not avoid creating empty evaporating overlays (Bug#9642).
12049 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12050 That is, do not delete an evaporating overlay if it becomes
12051 empty after its bounds are adjusted to fit within its buffer.
12052 This fix caused other problems, and I'm reverting it until we get
12053 to the bottom of them.
12055 2012-04-27 Chong Yidong <cyd@gnu.org>
12057 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12059 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12061 * xdisp.c (pos_visible_p): If the window start position is beyond
12062 ZV, start the display from buffer beginning. Prevents assertion
12063 violation in init_iterator when the minibuffer window is scrolled
12064 via the scroll bar.
12066 * window.c (window_scroll_pixel_based): Likewise.
12068 2012-04-27 Chong Yidong <cyd@gnu.org>
12070 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12072 2012-04-27 Glenn Morris <rgm@gnu.org>
12074 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12075 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12077 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12079 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12080 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12082 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12084 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12085 display element, check also the underlying string or buffer
12086 character. (Bug#11341)
12088 * w32menu.c: Include w32heap.h.
12089 (add_menu_item): If the call to AppendMenuW (via
12090 unicode_append_menu) fails, disable Unicode menus only if we are
12091 running on Windows 9X/Me.
12093 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12095 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12096 (xgetint): Add missing shift for LSB tags.
12098 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12100 * keyboard.c (read_char): Don't wipe echo area for select window
12101 events: These might get delayed via `mouse-autoselect-window'
12104 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12106 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12107 manipulation of :loaded-from data.
12109 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12111 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12112 now a cons (bug#11311).
12114 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12116 Do not create empty overlays with the evaporate property (Bug#9642).
12117 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12118 if it becomes empty after its bounds are adjusted to fit within
12119 its buffer. Without this fix, in a nonempty buffer (let ((o
12120 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12121 yields an empty overlay that has the evaporate property, which is
12122 not supposed to happen.
12124 Fix minor GTK3 problems found by static checking.
12125 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

12144 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12145 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12146 (__malloc_size_t, __malloc_ptrdiff_t):
12147 Remove. All uses removed, replaced by the definiens if needed,
12148 since we can assume C89 or better now.
12149 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12224 * alloc.c: Handle unusual debugging option combinations.
12225 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
12226 since the two debugging options are incompatible.
12227 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

12333 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
12334 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
12335 (r_alloc_sbrk): Now static.
12337 Improve ralloc.c interface checking.
12338 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
12339 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

12366 * s/netbsd.h, s/sol2-6.h:
12367 Remove definition of GC_MARK_STACK, since the default now works.
12368 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12369 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12370 no longer the default.
12371 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12373 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

12378 2012-04-14 Eli Zaretskii <eliz@gnu.org>
12380 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
12381 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
12383 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
12385 * nsterm.m (constrainFrameRect): Always constrain when there is only
12386 one screen (Bug#10962).
12388 2012-04-13 Ken Brown <kbrown@cornell.edu>
12390 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
12392 2012-04-13 Reuben Thomas <rrt@sc3d.org>
12394 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
12396 2012-04-11 Daniel Colascione <dancol@dancol.org>
12398 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12399 against is gone. It's better to use vfork now so that when Cygwin
12400 gains a new, working vfork, we use it automatically (bug#10398).
12402 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
12404 * window.c (save_window_save): Obey window-point-insertion-type.

12416 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
12417 (force_quit_count): New var.
12418 (handle_interrupt): Use it.
12420 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
12422 * w32.c (w32_delayed_load): Record the full path of the library
12423 being loaded (bug#10424).
12425 2012-04-09 Glenn Morris <rgm@gnu.org>
12427 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12428 not just in the obarray, before snarfing them. (Bug#11036)
12430 * Makefile.in ($(leimdir)/leim-list.el):
12431 Pass EMACS rather than BUILT_EMACS.
12433 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12435 * process.c (make_process):
12436 * process.h: Add integer `gnutls_handshakes_tried' member to
12439 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
12440 Add convenience `GNUTLS_LOG2i' macro.
12442 * gnutls.c (gnutls_log_function2i): Convenience log function.
12443 (emacs_gnutls_read): Use new log functions,
12444 `gnutls_handshakes_tried' process member, and
12445 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12446 attempts per process (connection).
12448 2012-04-09 Chong Yidong <cyd@gnu.org>
12450 * eval.c (Fuser_variable_p, user_variable_p_eh)
12451 (lisp_indirect_variable): Functions deleted.
12452 (Fdefvar): Caller changed.
12454 * callint.c (Finteractive, Fcall_interactively):
12455 * minibuf.c (Fread_variable): Callers changed.
12457 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12459 * xdisp.c (set_cursor_from_row): If the display string appears in
12460 the buffer at position that is closer to point than the position
12461 after the display string, display the cursor on the first glyph of
12462 the display string. Fixes cursor display when a 'display' text
12463 property immediately follows invisible text. (Bug#11094)
12465 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12467 composite.c: use 'double' consistently
12468 * composite.c (get_composition_id): Use 'double' consistently
12469 instead of converting 'float' to 'double' and vice versa; this is
12470 easier to understand and avoids a GCC warning.
12472 2012-04-09 Glenn Morris <rgm@gnu.org>
12474 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12475 preparation for dumping it with emacs. (Bug#4789)
12476 (leimdir): New variable.
12477 ($(leimdir)/leim-list.el): New rule.
12478 (emacs$(EXEEXT)): Depend on leim-list.el.
12480 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
12481 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
12482 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
12484 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
12486 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
12489 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
12491 * xml.c (init_libxml2_functions) [WINDOWSNT]:
12492 Remove unused local variable.
12494 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12496 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12497 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12498 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12499 objects, as mark_maybe_pointer will catch them otherwise.
12500 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12501 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
12503 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12505 Fix typo that broke non-Windows builds.
12506 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
12508 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12510 Support building on MS-Windows with libxml2.
12512 * makefile.w32-in (OBJ2): Add xml.$(O).
12513 (GLOBAL_SOURCES): Add xml.c.
12514 ($(BLD)/xml.$(O)): New dependency list.
12516 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12517 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12518 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12519 [!WINDOWSNT]: New macros.
12520 (init_libxml2_functions, libxml2_loaded_p): New functions.
12521 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12522 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12523 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12524 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12526 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12527 Call init_libxml2_functions before calling libxml2 functions.
12528 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12530 * emacs.c: Don't include libxml/parser.h.
12531 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12532 xmlCleanupParser directly.
12534 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12536 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12538 * indent.c (Fvertical_motion): If there is a display string at
12539 point, use it.vpos to compute how many lines to backtrack after
12540 move_it_to point. (Bug#11133)
12542 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12544 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12545 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12546 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12547 macros related to unification of CJK characters. For the details,
12548 see the discussion following the message here:
12549 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12551 2012-04-04 Chong Yidong <cyd@gnu.org>
12553 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12555 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12557 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12558 instead of alloca. (Bug#11138)
12560 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12562 * w32menu.c (is_simple_dialog): Properly check lisp types.
12565 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12567 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12568 position we get to after a call to move_it_to fails the
12569 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12570 only if we wind up in a string from display property. (Bug#11063)
12572 * window.c (Fdelete_other_windows_internal): Invalidate the row
12573 and column information about mouse highlight, so that redisplay
12574 restores it after reallocating the glyph matrices. (Bug#7464)
12576 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12577 string comes from a `display' text property, use the buffer
12578 position of that property as if we actually saw that position in
12580 (move_it_by_lines): Remove the assertion that
12581 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12582 violated when there's a before-string at the beginning of a line.
12585 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12587 * xdisp.c (append_space_for_newline): If the default face was
12588 remapped, use the remapped face for the appended newline.
12589 (extend_face_to_end_of_line): Use the remapped default face for
12590 extending the face to the end of the line.
12591 (display_line): Call extend_face_to_end_of_line when the default
12592 face was remapped. (Bug#11068)
12594 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12596 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12598 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12600 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12602 2012-03-27 Glenn Morris <rgm@gnu.org>
12604 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12607 2012-03-26 Kenichi Handa <handa@m17n.org>
12609 * dispextern.h (struct glyph): Fix previous change. Change the
12610 bit length of glyphless.ch to 25 (Bug#11082).
12612 2012-03-26 Chong Yidong <cyd@gnu.org>
12614 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12615 (command_loop_1): Use it; inhibit selection update for
12616 handle-select-window too (Bug#8996).
12618 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12620 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12622 2012-03-25 Kenichi Handa <handa@m17n.org>
12624 * dispextern.h (struct glyph): Change the bit length of
12625 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12627 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12629 * s/ms-w32.h (tzname): Include time.h before redirecting to
12630 _tzname. Fixes the MSVC build. (Bug#9960)
12632 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12634 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12637 * xterm.c (XTread_socket): Only modify handling_signal if
12638 !SYNC_INPUT. (Bug#11080)
12640 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12642 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12643 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12644 when fetching a multibyte character consumes more bytes than
12645 CHAR_BYTES returns, due to unification of CJK characters in
12646 string_char. (Bug#11073)
12648 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12650 * process.c (wait_reading_process_output): Handle pty disconnect
12651 by refraining from sending oneself a SIGCHLD (bug#10933).
12653 2012-03-22 Chong Yidong <cyd@gnu.org>
12655 * dispextern.h (struct it): New member string_from_prefix_prop_p.
12657 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12658 Mark string as coming from a prefix property.
12659 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12660 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12662 2012-03-21 Chong Yidong <cyd@gnu.org>
12664 * xfaces.c (Vface_remapping_alist): Doc fix.
12666 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12668 * w32proc.c (Fw32_set_console_codepage)
12669 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12672 2012-03-20 Chong Yidong <cyd@gnu.org>
12674 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12675 to reflect default non-nil value of redisplay-dont-pause.
12677 2012-03-19 Kenichi Handa <handa@m17n.org>
12679 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12680 it fit in a valid range (Bug#11003).
12682 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12684 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12685 that is not from display property, accept the row as a "cursor
12686 row" if one of the string's character has a non-nil `cursor'
12687 property. Fixes cursor positioning when there are newlines in
12688 overlay strings, e.g. in icomplete.el. (Bug#11035)
12690 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12692 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12694 2012-03-12 Chong Yidong <cyd@gnu.org>
12696 * eval.c (inhibit_lisp_code): Rename from
12697 inhibit_window_configuration_change_hook; move from window.c.
12699 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12700 * window.c (run_window_configuration_change_hook)
12701 (syms_of_window): Callers changed.
12703 2012-03-11 Chong Yidong <cyd@gnu.org>
12705 * keymap.c (Fkey_description): Doc fix (Bug#9700).
12707 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12709 2012-03-10 Chong Yidong <cyd@gnu.org>
12711 * frame.c (other_visible_frames): Don't assume the selected frame
12712 is visible (Bug#10955).
12714 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12716 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
12718 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
12720 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12721 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12724 2012-03-03 Glenn Morris <rgm@gnu.org>
12726 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12728 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12730 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12731 position past the first glyph_row that ends at ZV. (Bug#10902)
12732 (redisplay_window, next_element_from_string): Fix typos in
12734 (redisplay_window): Pass to move_it_vertically the margin in
12735 pixels, not in screen lines.
12737 2012-03-02 Glenn Morris <rgm@gnu.org>
12739 * buffer.c (buffer-list-update-hook): Doc fix.
12741 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12743 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12744 push_it before setting up the iterator for the first overlay
12745 string, even if we have an empty string loaded.
12746 (next_overlay_string): If there's an empty string on the iterator
12747 stack, pop the stack. (Bug#10903)
12749 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12751 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12752 Suggested by Stefan Monnier in
12753 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12754 * alloc.c (widen_to_Lisp_Object): New static function.
12755 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12756 and widening them to Lisp_Objects. This would work even if
12757 USE_LSB_TAG is defined and wide integers are used, which might
12758 happen in a future version of Emacs.
12760 2012-02-25 Chong Yidong <cyd@gnu.org>
12762 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12765 * xselect.c (Fx_selection_exists_p): Doc fix.
12766 (x_clipboard_manager_save_all): Print an informative message
12767 before saving to clipboard manager.
12769 2012-02-24 Chong Yidong <cyd@gnu.org>
12771 * keyboard.c (process_special_events): Handle all X selection
12772 requests in kbd_buffer, not just the next one (Bug#8869).
12774 2012-02-23 Chong Yidong <cyd@gnu.org>
12776 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12777 call when setting menu-bar-lines and tool-bar-lines parameters.
12778 (unwind_create_frame_1): New helper function.
12780 * window.c (inhibit_window_configuration_change_hook): New var.
12781 (run_window_configuration_change_hook): Obey it.
12782 (syms_of_window): Initialize it.
12784 2012-02-22 Chong Yidong <cyd@gnu.org>
12786 * xterm.c (x_draw_image_relief): Add missing type check for
12787 Vtool_bar_button_margin (Bug#10743).
12789 2012-02-21 Chong Yidong <cyd@gnu.org>
12791 * fileio.c (Vfile_name_handler_alist): Doc fix.
12793 * buffer.c (Fget_file_buffer): Protect against invalid file
12794 handler return value.
12796 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
12798 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
12799 when computing $valmask.
12801 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12802 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12803 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12804 It's useless in that case, and it can cause problems on hosts
12805 that allocate halves of EMACS_INT values separately.
12806 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12807 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12808 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12809 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12810 it avoids undefined behavior on hosts where shifting right by more
12811 than the word width has undefined behavior.
12813 2012-02-19 Chong Yidong <cyd@gnu.org>
12815 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12816 (Funhandled_file_name_directory, Ffile_name_as_directory)
12817 (Fdirectory_file_name, Fexpand_file_name)
12818 (Fsubstitute_in_file_name): Protect against invalid file handler
12819 return values (Bug#10845).
12821 2012-02-18 Eli Zaretskii <eliz@gnu.org>
12823 * .gdbinit (pitx): Fix incorrect references to fields of the
12826 2012-02-17 Chong Yidong <cyd@gnu.org>
12828 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
12830 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
12832 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
12833 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12835 2012-02-15 Chong Yidong <cyd@gnu.org>
12837 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12838 marked as special. Also, starting docstrings with * is obsolete.
12840 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
12842 * gnutls.c (emacs_gnutls_write): Fix last change.
12844 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
12846 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
12849 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
12851 * keymap.c (Fsingle_key_description): Handle char ranges.
12853 2012-02-12 Chong Yidong <cyd@gnu.org>

13428 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13429 verifies glyph row's hash code--we have just reallocated the

13594 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13595 is set, removing the need for VIRT_ADDRESS_VARIES.
13596 (PURE_P): Use a more-efficient implementation that needs just one

13603 consistency with the new puresize.h.
13604 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13605 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13611 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13612 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13613 behave as if the cursor position were at the window margin.
13615 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13616 and the cursor position is out of bounds, behave as if the cursor
13617 position were at the window margin. (Bug#10075)
13619 2011-11-18 Chong Yidong <cyd@gnu.org>
13621 * window.c (Fwindow_combination_limit): Make first argument

13640 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13642 * xdisp.c (row_hash): New function, body extracted from
13643 compute_line_metrics.
13644 (compute_line_metrics): Call row_hash, instead of computing the
13647 * dispnew.c (verify_row_hash): Call row_hash for computing the
13648 hash code of a row, instead of duplicating code from xdisp.c.
13650 * dispextern.h (row_hash): Add prototype.
13652 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13654 * frame.c (delete_frame): Don't delete the terminal when the last

13708 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13709 current_matrix and desired_matrix. (Bug#9990)
13710 (verify_row_hash) [XASSERTS]: New function.

13755 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13757 Avoid some portability problems by eschewing 'extern inline' functions.
13758 The trivial performance wins aren't worth the portability hassles; see
13759 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13761 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

13810 This is also needed for porting to any host where GC_MARK_STACK is
13811 not GC_MAKE_GCPROS_NOOPS.
13812 (which_symbols): Use it.
13814 2011-11-07 Kenichi Handa <handa@m17n.org>

13827 * xmenu.c (cleanup_widget_value_tree): New function.
13828 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
13829 calling free_menubar_widget_value_tree directly (Bug#9830).
13831 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
13833 Fix some portability problems with 'inline'.

13835 (window_box_width, window_box_left, window_box_left_offset)
13836 (window_box_right, window_box_right_offset): Declare extern.
13837 Otherwise, these inline functions do not conform to C99 and
13838 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13839 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13840 * intervals.c (adjust_intervals_for_insertion)
13841 (adjust_intervals_for_deletion): Now extern, because otherwise the

13843 (static_offset_intervals): Remove.
13844 (offset_intervals): Rewrite using the old contents of
13845 static_offset_intervals. The old version didn't conform to C99
13846 because an extern inline function contained a reference to an
13847 identifier with static linkage.
13849 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
13851 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

13871 argument, since it makes no sense to pass a live window and for
13872 consistency with window-child.

13912 Move terminal->reference_count++ just before making the frame
13913 official. Move initialization of image_cache_refcount and
13914 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

13954 previous/next-single-property-change returns nil, treat that as
13955 the beginning or the end of the buffer. (Bug#9955)
13957 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
13959 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

13994 past the beginning of the current glyph matrix.
13996 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
13998 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

14082 (w32font_open_internal, compute_metrics):
14083 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14084 instead of calling the "wide" APIs directly.

14088 * w32.h (syms_of_w32font): Add prototype.

14097 2011-10-27 Chong Yidong <cyd@gnu.org>
14099 * process.c (make_process): Set gnutls_state to NULL.
14101 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14102 non-NULL, regardless of GNUTLS_INITSTAGE.

14151 (bidi_resolve_weak): Don't enter the expensive loop if the current
14152 position is before next_en_pos. Record the bidi type of the first
14153 non-ET, non-BN character we find, in addition to its position.
14154 (bidi_level_of_next_char): Invalidate next_en_type when
14155 next_en_pos is over-stepped.
14157 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14159 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14160 * editfns.c: Rewrite current-time-zone so that it invokes
14161 the equivalent of (format-time-string "%Z") to get the time zone name.
14162 This fixes a bug when the time zone name contains characters that
14163 need converting from the system time locale to Emacs internal format.
14164 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14165 that patch fixed format-time-string to do the conversion, but
14166 I forgot to fix current-time-zone.
14167 (format_time_string): New function, containing most of
14168 what Fformat_time_string used to contain.
14169 (Fformat_time_string): Rewrite in terms of format_time_string.
14170 This doesn't change this function's behavior.
14171 (current-time-zone): Rewrite to use format_time_string.
14172 This fixes the bug reported by Michael Schierl in
14173 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14174 Jason Rumney's 2007-06-07 change worked around this bug, but
14176 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14178 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14180 * xdisp.c (start_display): If the character at POS is displayed
14181 via a display vector, reset IT->current.dpvec_index to zero.
14182 (try_window_reusing_current_matrix): If a line ends in a display
14183 vector or the next line starts in a display vector, continue
14184 redrawing the window even though the character position of
14185 start_row was reached.
14188 2011-10-18 Chong Yidong <cyd@gnu.org>
14190 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14191 with nobreak-char-display too.
14193 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14195 Fix part 3 of bug#9771.
14196 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14197 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14198 non-neutral characters if the current character is a paragraph
14199 separator (a.k.a. Newline). This avoids running the same
14200 expensive loop twice, once when we consume the preceding newline
14201 and the other time when the line actually needs to be displayed.
14202 Avoid the loop when we see neutrals on the base embedding level
14203 following a character whose directionality is the same as the
14204 paragraph's. This avoids running the expensive loop when a line
14205 ends in a long sequence of neutrals, like control characters.
14206 Add assertion against STRONG_AL type. Slightly rearrange code
14207 that determines the type of a neutral given the first non-neutral
14209 (bidi_level_of_next_char): Set next_en_pos to zero when
14210 invalidating its info.
14212 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14214 * xdisp.c (push_display_prop): Determine whether to record string
14215 or buffer position by IT->string, not by IT->method. Allow
14216 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14217 (move_it_vertically_backward): Don't look for character position
14218 immediately after the newline when in a continuation line.
14221 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14223 * window.c (coordinates_in_window): Rewrite and delabelize
14224 vertical border check. (Bug#5357) (Bug#9618)
14226 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14228 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14229 errors in XSetWindowBorder (bug#9310).
14231 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14233 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14234 avoid crash when xmalloc overrun checking is enabled.
14236 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14238 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14239 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14240 cursor motion with <left> and <right> arrow keys.
14242 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14243 some callers set that themselves.
14245 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14247 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14248 display string and the previous row comes from the same string and
14249 is empty. (Bug#9739) (Bug#9738)
14251 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14253 * doc.c (get_doc_string): Encode file name (bug#9735).
14255 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14257 * bidi.c (bidi_level_of_next_char):
14258 * xdisp.c (get_visually_first_element): Remove old incorrect
14259 comments regarding the Unicode Line Separator character.
14261 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14263 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14265 * alloc.c (Fgc_status): Do not access beyond zombies array
14266 boundary if nzombies > MAX_ZOMBIES.
14267 * alloc.c (dump_zombies): Add missing format specifier.
14269 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14271 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14272 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14274 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14275 Some packages use them to denote characters with modifiers.
14277 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14279 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14280 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14281 matching a pp-number. Rename parameter var to var1.
14283 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14285 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14287 2011-10-08 Glenn Morris <rgm@gnu.org>
14289 * callint.c (Fcall_interactively): Give a more explicit error for the
14290 'c' case with a non-character input. (Bug#8479)
14292 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14294 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14296 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14297 lines that are hscrolled on the left.
14299 * dispnew.c (buffer_posn_from_coords): Account for a possible
14300 presence of header-line. (Bug#4426)
14302 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14304 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14305 Don't advertise functionality which we discourage or doesn't work.
14307 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14309 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14310 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14311 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14312 this makes Emacs dump core during garbage collection on rare
14313 occasions. sizeof is obviously inferior to offsetof here, so
14314 stick with offsetof.
14315 (GC_POINTER_ALIGNMENT): New macro.
14316 (mark_memory): Omit 3rd (offset) arg; caller changed.
14317 Don't assume EMACS_INT alignment is the same as pointer alignment.
14319 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14321 * keyboard.c (read_key_sequence_remapped): New var.
14322 (read_key_sequence): Compute remapping in the right buffer.
14323 (command_loop_1): Use read_key_sequence's remapping directly.
14325 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14327 * dired.c (file_name_completion): Don't expand file name.
14328 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14329 before checking file name handler.
14331 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14332 they've been requested explicitly (bug#9591).
14334 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14336 * keymap.c (Fsingle_key_description): Use make_specified_string
14337 instead of build_string to build string from push_key_description.
14340 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14342 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14343 This fixes a Y2038 bug on 64-bit hosts.
14344 * buffer.c (reset_buffer):
14345 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14346 (Fclear_buffer_auto_save_failure):
14347 Use 0, not -1, to represent an unset failure time, since time_t
14348 might not be signed.
14350 Remove dependency on glibc malloc internals.
14351 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14352 Move back here from lisp.h, but with their new implementations.
14353 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14354 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14355 * charset.c (charset_table_init): New static var.
14356 (syms_of_charset): Use it instead of xmalloc. This removes a
14357 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14358 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14359 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14360 Move back to alloc.c.
14361 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14362 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14364 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14366 * nsterm.m (windowDidResize): Call x_set_window_size only when
14367 ns_in_resize is true. Otherwise set pixelwidth/height and
14368 call change_frame_size (Bug#9628).
14370 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14372 Port --enable-checking=all to Fedora 14 x86-64.
14373 * charset.c (syms_of_charset): Also account for glibc malloc's
14374 internal overhead when calculating the initial malloc maximum.
14376 Port --enable-checking=all to Fedora 14 x86.
14377 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14379 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14380 (overrun_check_realloc, overrun_check_free):
14381 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14382 That way, xmalloc returns a properly-aligned pointer even if
14383 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14384 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14385 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14386 into account when calculating the initial malloc maximum.
14387 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14388 Move here from alloc.c, so that charset.c can use it too.
14389 Properly align; the old code wasn't right for common 32-bit hosts
14390 when configured with --enable-checking=all.
14391 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14392 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14394 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14396 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14399 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14401 * xdisp.c (compute_display_string_end): If there's no display
14402 string at CHARPOS, return -1.
14404 * bidi.c (bidi_fetch_char): When compute_display_string_end
14405 returns a negative value, treat the character as a normal
14406 character not covered by a display string. (Bug#9624)
14408 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14410 * lread.c (Fread_from_string): Fix typo in docstring.
14412 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14414 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14415 newline, reseat the iterator instead of bidi-iterating there one
14416 character at a time. (Bug#9610)
14417 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14418 TO_CHARPOS if the bidi iterator is at base embedding level.
14420 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14422 * lread.c (readevalloop): Use correct code for NBSP.
14423 (read1): Likewise. (Bug#9608)
14425 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14427 * dbusbind.c (Fdbus_register_signal): When service is not
14428 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14430 2011-09-25 Glenn Morris <rgm@gnu.org>
14432 * buffer.c (truncate-lines): Doc fix.
14434 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14436 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14437 (Fset_window_next_buffers): Doc fix.
14439 2011-09-24 Glenn Morris <rgm@gnu.org>
14441 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14443 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14445 Fix minor problems found by static checking.
14446 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14447 * indent.c (Fvertical_motion): Fix == vs = typo.
14449 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14451 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14452 Default value is now t. Doc fix.
14454 * indent.c (Fvertical_motion): Compute and apply the overshoot
14455 logic when moving up, not only when moving down. Fix the
14456 confusing name and values of the it_overshoot_expected variable;
14457 logic changes accordingly. (Bug#9254) (Bug#9549)
14459 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14460 CHARPOS is covered by a display string which includes newlines.
14461 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14462 is covered by a display string with embedded newlines.
14464 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14466 * dbusbind.c (Fdbus_register_signal): Add match rule to
14467 Vdbus_registered_objects_table. (Bug#9581)
14468 (Fdbus_register_method, Vdbus_registered_objects_table):
14471 2011-09-24 Jim Meyering <meyering@redhat.com>
14473 do not ignore write error for any output size
14474 The previous change was incomplete.
14475 While it makes emacs --batch detect the vast majority of stdout
14476 write failures, errors were still ignored whenever the output size is
14477 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14478 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14479 && echo FAIL: ignored write error
14480 FAIL: ignored write error
14481 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14482 && echo FAIL: ignored write error
14483 FAIL: ignored write error
14484 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14486 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14488 * emacs.c (Fkill_emacs): In noninteractive mode exit
14489 non-successfully if a write error occurred on stdout. (Bug#9574)
14491 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14493 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14496 * dispextern.h (struct it): Update the comment documenting what
14499 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14501 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14502 a display string, extend search for cursor position to end of row.
14503 (find_row_edges): If the row ends in a newline from a display
14504 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14505 Handle the case of a display string with multiple newlines.
14506 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14507 non-empty line. Fixes confusing cursor motion with arrow keys at
14508 the beginning of a line that starts with whitespace.
14510 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14512 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14515 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14517 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14518 boolean (Bug#9154).
14520 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14522 * xdisp.c (display_line): Record maximum and minimum buffer
14523 positions even if no glyphs were produced (e.g., by a zero-width
14524 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14525 buffer positions that will be removed from the glyph row because
14527 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14528 column is beyond frame width: don't subtract 1 "pixel" when
14529 computing width of the stretch.
14530 (reseat_at_next_visible_line_start): Undo the change made on
14531 2011-09-17 that saved paragraph information and restored it after
14532 the call to `reseat'. (Bug#9545)
14534 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14536 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14537 and turn window cursor on if cleared (Bug#9415).
14539 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14541 * search.c (boyer_moore): Take unibyte characters from pattern
14542 literally. (Bug#9458)
14544 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14546 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14548 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14550 Fix minor problem found by static checking.
14551 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14552 initialized, to pacify gcc -Wuninitialized.
14554 * fileio.c: Report proper errno when syscall falls.
14555 (Finsert_file_contents): Save and restore errno,
14556 so that report_file_error outputs the correct diagnostic.
14557 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14559 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14561 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14563 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14565 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14566 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14568 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14570 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14571 about the current paragraph and restore it after the call to reseat.
14573 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14574 (bidi_find_paragraph_start): Search back for paragraph beginning
14575 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14576 (bidi_move_to_visually_next): Only trigger paragraph-related
14577 computations when the last character is a newline or at EOB, not
14578 just any NEUTRAL_B. (Bug#9470)
14580 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14581 truncated lines if point is covered by a display string. (Bug#9524)
14583 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14585 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14586 (cons_to_x_long): New function.
14587 (lisp_data_to_selection_data): Use it. Correct the test for
14588 short-versus-long data; it was negated. Break out of vector
14589 loop, for efficiency, when a long datum is discovered.
14591 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14593 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14595 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14597 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14598 GCC PR/17406) by declaring this function with external scope.
14600 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14602 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14603 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14605 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14607 * editfns.c (Fformat): Correctly handle text properties on "%%".
14609 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14611 * xterm.c (x_draw_composite_glyph_string_foreground):
14612 * w32term.c (x_draw_composite_glyph_string_foreground):
14613 * term.c (encode_terminal_code):
14614 * composite.c (composition_update_it, get_composition_id):
14615 * xdisp.c (get_next_display_element)
14616 (fill_composite_glyph_string): Add comments about special meaning
14617 of TAB characters in a composition.
14619 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14621 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14622 This occurs when processing a multibyte format.
14623 Problem reported by Wolfgang Jenker.
14625 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14627 * xdisp.c (try_cursor_movement): Only check for exact match if
14628 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14630 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14632 Remove unused external symbols.
14633 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14634 * xdisp.c (calc_pixel_width_or_height): Now static.
14635 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14636 * indent.c (check_display_width):
14637 * w32term.c: Fix comment to match code.
14638 * xterm.c, xterm.h (x_catching_errors): Remove.
14640 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14642 * xselect.c: Use signed conversions more consistently (Bug#9498).
14643 (selection_data_to_lisp_data): Assume incoming selection data are
14644 signed integers, not unsigned. This is to be consistent with
14645 outgoing selection data, which was modified to use signed integers
14646 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14647 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14648 expects long, not unsigned long.
14650 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14652 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14653 computation of loop end. Reported by Johan Bockgård
14656 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14658 * frame.c (Fother_visible_frames_p): Function deleted.
14660 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14662 * indent.c (compute_motion): Process display vector front to back
14663 rather than the other way around. (Bug#2496)
14665 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14667 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14669 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14671 * minibuf.c (Fread_from_minibuffer): Doc fix.
14673 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14675 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14676 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14678 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14680 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14681 value for non-existent files.
14683 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14685 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14686 set its "size" to -1. This will set the modtime_size field of
14687 the corresponding buffer to -1, which is what
14688 verify-visited-file-modtime expects for files that do not exist.
14691 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14693 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14695 * lisp.h: ... from here. push_key_description is no longer
14696 defined in keyboard.c, so its declaration should not be in
14697 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14698 logically belongs with push_key_description.
14700 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14702 * buffer.h: Include <sys/types.h> instead of <time.h>.
14703 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14704 Problem reported by Herbert J. Skuhra.
14706 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14708 * xml.c (parse_region): Make the parsing work for
14709 non-comment-starting XML files again (bug#9144).
14711 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14713 * image.c (gif_load): Fix calculation of bottom and right corner.
14716 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14718 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14719 redisplay in small windows.
14721 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14723 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14725 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14727 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14728 Operate on live windows only.
14730 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14732 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14734 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14736 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14737 only under bidi iteration.
14739 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14741 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14743 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14745 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14746 Without this fix, the command to link temacs failed due to an
14747 undefined symbol __builtin_isnan. This is because
14748 /usr/include/iso/math_c99.h #defines isnan(x) to
14749 __builtin_isnan(x), but the bundled gcc, which identifies itself
14750 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14752 * floatfns.c (isnan): #undef, and then #define to a clone of
14754 (Fisnan): Always define, since it's always available now.
14755 (syms_of_floatfns): Always define isnan at the Lisp level.
14757 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14759 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14761 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14763 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14764 The previous code assumed that file offsets (off_t values) fit in
14765 EMACS_INT variables, which is not true on typical 32-bit hosts.
14766 The code messed up by falsely reporting buffer overflow in cases
14767 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14768 when "big" contains more than 2**29 bytes, even though this
14769 inserts just one byte and does not overflow the buffer.
14770 (Finsert_file_contents): Store file offsets as off_t
14771 values, not as EMACS_INT values. Check for overflow when
14772 converting between EMACS_INT and off_t. When checking for
14773 buffer overflow or for overlap, take the offsets into account.
14774 Don't use EMACS_INT for small values where int suffices.
14775 When checking for overlap, fix a typo: ZV was used where
14776 ZV_BYTE was intended.
14777 (Fwrite_region): Don't assume off_t fits into 'long'.
14778 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14780 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14782 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14784 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14786 sprintf-related integer and memory overflow issues (Bug#9412).
14788 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14789 (esprintf, exprintf, evxprintf): New functions.
14790 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14791 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14792 (modify_event_symbol): Do not assume that the length of
14793 name_alist_or_stem is safe to alloca and fits in int.
14794 (Fexecute_extended_command): Likewise for function name and binding.
14795 (Frecursion_depth): Wrap around reliably on integer overflow.
14796 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14797 since some callers pass EMACS_INT values.
14798 (Fsingle_key_description): Don't crash if symbol name contains more
14799 than MAX_ALLOCA bytes.
14800 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14801 (get_minibuffer): Arg is now EMACS_INT, not int.
14802 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14803 (esprintf, exprintf, evxprintf): New decls.
14804 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14806 * dbusbind.c (signature_cat): New function.
14807 (xd_signature, Fdbus_register_signal):
14808 Do not overrun buffer; instead, report string overflow.
14810 * dispnew.c (add_window_display_history): Don't overrun buffer.
14811 Truncate instead; this is OK since it's just a log.
14813 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14814 even if the time zone offset is outlandishly large.
14815 Don't mishandle offset == INT_MIN.
14817 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14818 when creating daemon; the previous buffer-overflow check was incorrect.
14820 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14821 which has the guts of the old verror function.
14823 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14824 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14826 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14827 (font_unparse_xlfd): Don't blindly alloca long strings.
14828 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14829 fits in int, when using sprintf. Use single snprintf to count
14830 length of string rather than counting it via multiple sprintfs;
14831 that's simpler and more reliable.
14832 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14833 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14834 sprintf, in case result does not fit in int.
14836 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14837 (fontset_from_font): Print it.
14839 * frame.c (tty_frame_count): Now printmax_t, not int.
14840 (make_terminal_frame, set_term_frame_name): Print it.
14841 (x_report_frame_params): In X, window IDs are unsigned long,
14842 not signed long, so print them as unsigned.
14843 (validate_x_resource_name): Check for implausibly long names,
14844 and don't assume name length fits in 'int'.
14845 (x_get_resource_string): Don't blindly alloca invocation name;
14846 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14849 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14850 (xg_check_special_colors, xg_set_geometry):
14851 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14853 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14854 Use esprintf, not sprintf, in case result does not fit in int.
14856 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14857 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14858 it as a large positive number.
14859 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14860 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14862 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14863 in case result does not fit in int.
14865 * print.c (float_to_string): Detect width overflow more reliably.
14866 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14867 buffer overrun. Don't assume list length fits in 'int'. Treat
14868 print length of 0 as 0, not as infinity; to be consistent with other
14869 uses of print length in this function. Don't overflow print length
14870 index. Don't assume hash table size fits in 'long', or that
14871 vectorlike size fits in 'unsigned long'.
14873 * process.c (make_process): Use printmax_t, not int, to format
14874 process-name gensyms.
14876 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14878 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14879 to avoid potential buffer overrun.
14881 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14882 if X resource line is longer than 512 bytes.
14884 * xfns.c (x_window): Make sprintf buffer a bit bigger
14885 to avoid potential buffer overrun.
14887 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14889 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14891 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14893 Integer overflow fixes for scrolling, etc.
14894 Without these, Emacs silently mishandles large integers sometimes.
14895 For example, "C-u 4294967297 M-x recenter" was treated as if
14896 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14898 * xdisp.c (try_window_id): Check Emacs fixnum range before
14899 converting to 'int'.
14901 * window.c (window_scroll_line_based, Frecenter):
14902 Check that an Emacs fixnum is in range before assigning it to 'int'.
14903 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14904 values converted from Emacs fixnums.
14905 (Frecenter): Don't wrap around a line count if it is out of 'int'
14906 range; instead, treat it as an extreme value.
14907 (Fset_window_configuration, compare_window_configurations):
14908 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14910 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14911 that can exceed INT_MAX. Check that EMACS_INT value is in range
14912 before assigning it to the (possibly-narrower) index.
14913 (match_limit): Don't assume that a fixnum can fit in 'int'.
14915 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14918 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14919 (Fvertical_motion): Don't wrap around LINES values that don't fit
14920 in 'int'. Instead, treat them as extreme values. This is good
14921 enough for windows, which can't have more than INT_MAX lines anyway.
14923 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14925 * Require libxml/parser.h to avoid compilation warning.
14927 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14929 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14930 since this reportedly can destroy thread storage.
14932 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14934 * syntax.c (find_defun_start): Update all cache variables if
14935 exiting early (Bug#9401).
14937 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14939 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14941 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14942 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14943 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14945 * term.c (tty_append_glyph): New function.
14946 (produce_stretch_glyph): Static function and its prototype deleted.
14948 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14951 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14953 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14954 when checking :margin (Bug#9390).
14955 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14956 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14957 so that the name doesn't mislead. All uses changed.
14959 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14961 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14964 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14966 * xdisp.c (move_it_to): Don't bail out early when reaching
14967 position beyond to_charpos, if we are scanning backwards.
14968 (move_it_vertically_backward): When DY == 0, make sure we get to
14969 the first character in the line after the newline.
14971 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14973 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14974 (ccl_driver): Do not generate an out-of-range pointer.
14975 (Fccl_execute_on_string): Remove unnecessary check for
14976 integer overflow, noted by Stefan Monnier in
14977 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14978 Remove a FIXME that didn't need fixing.
14979 Simplify the newly-introduced buffer reallocation code.
14981 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14983 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14985 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14987 Integer and memory overflow issues (Bug#9196).
14989 * doc.c (get_doc_string): Rework so that
14990 get_doc_string_buffer_size is the actual buffer size, rather than
14991 being 1 less than the actual buffer size; this makes xpalloc more
14994 * image.c (x_allocate_bitmap_record, cache_image):
14995 * xselect.c (Fx_register_dnd_atom):
14996 Simplify previous changes by using xpalloc.
14998 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14999 since either will do and ptrdiff_t is convenient with xpalloc.
15001 * charset.c (charset_table_size)
15002 (struct charset_sort_data.priority): Now ptrdiff_t.
15003 (charset_compare): Don't overflow if priorities differ greatly.
15004 (Fsort_charsets): Don't assume list length fits in int.
15005 Check for size-calculation overflow when allocating sort data.
15006 (syms_of_charset): Allocate an initial charset table that is
15007 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15009 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15011 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15012 The actual value is always <= INT_MAX, and leaving it unsigned made
15013 overflow checking harder.
15015 * dispextern.h (struct glyph_matrix.rows_allocated)
15016 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15017 with xpalloc. The values are still always <= INT_MAX.
15019 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15021 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15022 (SAFE_NALLOCA): New macro.
15024 * region-cache.c (struct boundary.pos, find_cache_boundary)
15025 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15026 (set_cache_region, invalidate_region_cache)
15027 (revalidate_region_cache, know_region_cache, region_cache_forward)
15028 (region_cache_backward, pp_cache):
15029 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15030 so that ptrdiff_t * can be passed to xpalloc.
15031 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15032 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15033 (pp_cache): Don't assume cache_len fits in int.
15034 * region-cache.h: Adjust extern decls to match.
15036 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15037 EMACS_INT, since either will do, for xpalloc.
15039 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15040 (xnmalloc, xnrealloc, xpalloc): New functions.
15042 * bidi.c (bidi_shelve_header_size): New constant.
15043 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15044 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15046 * bidi.c (bidi_cache_shrink):
15047 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15049 Don't update size of array until after memory allocation succeeds,
15050 because xmalloc/xrealloc may not return.
15051 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15052 now that we have proper integer overflow checking.
15053 (record_overlay_string, overlay_strings): Catch overflows when
15054 calculating size of overlay_str_buf.
15056 * callproc.c (Fcall_process): Check for size overflow when
15057 calculating size of args2.
15058 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15059 Normally we prefer signed values, but sticking with ptrdiff_t would
15060 require adding more-complicated checks.
15062 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15063 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15064 Redo buffer-overflow calculations to avoid integer overflow.
15065 Add a FIXME comment where memory seems to be over-allocated.
15067 * character.c (Fstring): Check for size-calculation overflow.
15069 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15070 unnecessary integer overflow. Check for size overflow.
15071 (encode_coding_object): Don't update size until xmalloc succeeds.
15073 * composite.c (get_composition_id): Check for overflow in glyph
15074 length calculations.
15076 Integer and memory overflow fixes for display code.
15077 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15078 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15079 (scrolling_window): Check for overflow in size calculations.
15080 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15081 Don't assume glyph table len fits in int.
15082 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
15083 (row_table_size): Now ptrdiff_t, not int.
15084 (scrolling_window): Avoid overflow in size calculations.
15085 Don't update size until allocation succeeds.
15086 * fns.c (concat): Check for overflow in size calculations.
15087 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15088 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15089 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15091 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15092 (get_doc_string): Check for size calculation overflow.
15093 Don't update size until allocation succeeds.
15094 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15095 EMACS_INT, where ptrdiff_t will do.
15096 (Fsubstitute_command_keys): Check for string overflow.
15098 * editfns.c (set_time_zone_rule): Don't assume environment length
15100 (message_length): Now ptrdiff_t, not int.
15101 (Fmessage_box): Don't update size until allocation succeeds.
15102 Don't assume message length fits in int.
15103 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15105 * emacs.c (main): Do not reallocate argv, since there is a null at
15106 the end that can be overwritten, and this way there's no need to
15107 worry about size-calculation overflow.
15108 (sort_args): Check for size-calculation overflow.
15110 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15112 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15114 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15115 (x_set_scroll_bar_width, x_figure_window_size):
15116 Check for integer overflow.
15117 (x_set_alpha): Do not assume XINT fits in int.
15119 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15120 This is for the members text_lines, text_cols, total_lines, total_cols,
15121 where the system imposes an 'int' limit.
15123 * fringe.c (Fdefine_fringe_bitmap):
15124 Don't update size until alloc works.
15126 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15127 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15129 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15130 Check for size-calculation overflow.
15131 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15132 do, as we prefer signed integers.
15133 (id_to_widget.max_size, id_to_widget.used)
15134 (xg_store_widget_in_map, xg_remove_widget_from_map)
15135 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15136 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15137 Use and return ptrdiff_t, not int.
15138 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15139 * gtkutil.h: Change prototypes to match the above.
15141 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15142 are duplicate now that they've been promoted to lisp.h.
15143 (x_allocate_bitmap_record, x_alloc_image_color)
15144 (make_image_cache, cache_image, xpm_load):
15145 Don't update size until alloc is done.
15146 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15148 Check for size calculation overflow.
15149 (ct_colors_allocated_max): New constant.
15150 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

15188 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15189 for command line length. Do not attempt to address one before the
15190 beginning of an array, as that's not portable.
15192 * term.c (max_frame_lines): Remove; unused.

15222 memory exhaustion (the usual treatment), rather than aborting.
15224 * xfns.c (x_encode_text, x_set_name_internal)
15225 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15226 sizes, since they can exceed INT_MAX in size. Check for size
15227 calculation overflow.

15230 (xg_select): Check for size calculation overflow.
15231 Don't update size until alloc done.
15233 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15234 as sprintf is limited to int lengths.
15236 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15237 (X_LONG_MIN): New macros.
15238 Use them to make the following changes clearer.
15239 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15240 This change doesn't affect the value now, but it may help remind
15241 future maintainers not to raise the value too much later.
15242 (SELECTION_QUANTUM): Remove, replacing with ...
15243 (selection_quantum): ... new function, which avoids overflow.
15245 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15246 assumption that selection length fits in 'int'.

15263 Don't store size until memory allocation succeeds.
15264 (x_get_window_property): Plug memory leak on memory exhaustion.
15265 Don't double-block input; malloc is safe here. Don't assume 2**34
15266 - 4 fits in unsigned long. Add an xassert to check
15267 XGetWindowProperty overflow. Be more careful about overflow
15268 calculations, and distinguish size from memory overflow better.
15269 (receive_incremental_selection): When tracing, don't assume
15270 unsigned int is less than INT_MAX.
15271 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

15275 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15276 result parameters unless successful. Rely on cons_to_unsigned
15277 to report problems with elements; the old code wasn't right anyway.
15278 (x_check_property_data): Check for int overflow; we cannot use
15279 a wider type due to X limits.

15312 * lisp.h (hash_lookup, hash_put):
15313 * minibuf.c (Ftest_completion):
15314 Use ptrdiff_t for hash table indexes, not int (which is too
15315 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15316 32-bit --with-wide-int hosts).
15318 * charset.c (Fdefine_charset_internal): Check for integer overflow.

15347 * xterm.c: Don't go over XClientMessageEvent limit.
15348 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15349 (x_send_scroll_bar_event): Likewise. Check that the size does not
15350 exceed limits imposed by XClientMessageEvent, as well as the usual
15351 ptrdiff_t and size_t limits.

15354 (make_lispy_movement): Use same integer type in forward decl
15355 that is used in the definition.
15356 (read_key_sequence, keyremap_step):
15357 Change bufsize argument back to int, undoing my 2011-03-30 change.
15358 We prefer signed types, and int is wide enough here.
15359 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15360 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15361 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15362 length, not size_t. Use ptrdiff_t for index, not int.
15363 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15364 possibility of integer overflow.

15392 Prefer int to unsigned where either will do.
15393 (tiff_handler): New function, combining the cores of the
15394 old tiff_error_handler and tiff_warning_handler.
15395 This function is rewritten to use vsnprintf and thereby avoid
15396 stack buffer overflows. It uses only the features of vsnprintf
15397 that are common to both POSIX and native Microsoft.
15398 (tiff_error_handler, tiff_warning_handler): Use it.
15399 (tiff_load, gif_load, imagemagick_load_image):
15400 Don't assume :index value fits in 'int'.
15401 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15402 (imagemagick_load_image): Check that crop parameters fit into
15403 the integer types that MagickCropImage accepts. Don't assume
15404 Vimagemagick_render_type has a nonnegative value. Don't assume
15405 size_t fits in 'long'.
15406 (gs_load): Use printmax_t to print the widest integers possible.

15443 buffers, return left-to-right.
15444 (set_cursor_from_row): Consider candidate row a win if its glyph

15446 positioning on the newline at EOL of R2L text within L2R
15447 paragraph, and vice versa.
15448 (try_cursor_movement): Check continued rows, in addition to
15449 continuation rows. Fixes unwarranted scroll when point enters a
15450 continued line of R2L text within an L2R paragraph, or vice versa.
15451 (cursor_row_p): Consider the case of point being equal to
15452 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

15482 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15483 candidate is selected by the mouse, and that candidate has a
15484 composed character under the mouse.
15486 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15487 coordinates reported by pos-visible-in-window-p for a composed
15488 character in column zero.

15497 consider it a hit if to_charpos is anywhere in the range of the
15498 composed buffer positions.
15500 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15502 * image.c (gif_load): Don't assume that each subimage has the same
15503 dimensions as the base image. Handle disposal method that is
15504 "undefined" by the gif spec (Bug#9335).
15506 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15508 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15520 with a composed character.
15522 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15524 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15525 character bidirectional type, use STRONG_L instead. Fixes crashes
15526 in a buffer produced by `describe-categories'.
15528 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15529 members before the level stack, so they would be saved and
15530 restored when copying iterator state. Fixes incorrect reordering
15531 around TABs covered by display properties.

15598 2011-08-14 Kenichi Handa <handa@m17n.org>
15600 * process.c (create_process): Call setup_process_coding_systems
15601 after the pid of the process is set to -1 (Bug#8162).
15603 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15605 * xdisp.c (move_it_in_display_line_to): Don't invoke
15606 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15607 ppos_it. Fixes vertical cursor motion when line beginning is
15608 covered by an image. (Bug#9296)
15610 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15612 * nsterm.h (ns_run_ascript): Declare.
15613 (NSAPP_DATA2_RUNASSCRIPT): Define.
15615 * nsfns.m (as_script, as_result, as_status): New static variables.
15616 (ns_run_ascript): New function.
15617 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15618 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15619 the event loop. Get status from as_status (Bug#7276).
15621 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15622 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15623 the event loop (Bug#7276).
15625 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15627 * gnutls.c (QCgnutls_bootprop_priority)
15628 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
15629 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
15630 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
15631 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
15632 (QCgnutls_bootprop_verify_hostname_error)
15633 (QCgnutls_bootprop_callbacks_verify): Rename from
15634 Qgnutls_bootprop_..., all uses changed.
15636 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
15639 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
15641 * xfaces.c (Qframe_set_background_mode): Now static.
15642 * dispextern.h (Qframe_set_background_mode): Remove decl.
15644 * process.c (Fnetwork_interface_info): Declare local only if needed.
15646 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
15648 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15649 (Fnetwork_interface_list): Allocate in increments of bytes instead
15650 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15651 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15653 (struct ifflag_def): notrailers is smart on OSX.
15654 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15655 Get hardware address with getifaddrs if available.
15657 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15659 * xdisp.c (iterate_out_of_display_property): xassert that
15660 IT->position is set to within IT->object's boundaries. Break from
15661 the loop as soon as EOB is reached; avoids infloops in redisplay
15662 when IT->position is set up wrongly due to some bug.
15663 Set IT->current to match the bidi iterator unconditionally.
15664 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15665 entry. Force push_it to save on the stack the current
15666 buffer/string position, to be restored by pop_it. Fix flags in
15667 the iterator structure wrt the object coming from a display
15668 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15669 properties. (Bug#9284)
15671 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15673 * fontset.c (fontset_get_font_group): Add proper type checks.
15676 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15678 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
15679 and LC_VERSION_MIN_MACOSX.
15680 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
15681 (dump_it) [LC_FUNCTION_STARTS]: Use it.
15683 2011-08-08 Eli Zaretskii <eliz@gnu.org>
15685 * xdisp.c (forward_to_next_line_start): Allow to use the
15686 no-display-properties-and-no-overlays under bidi display.
15687 Set disp_pos in the bidi iterator to avoid searches for display
15688 properties and overlays.
15690 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15692 * editfns.c (Fset_time_zone_rule): Document relationship with the
15695 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
15696 the font entity extracted from the cache (Bug#8109).
15698 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15700 * composite.c (autocmp_chars): Don't reset point. That is done by
15701 restore_point_unwind (Bug#5984).
15703 2011-08-07 Juri Linkov <juri@jurta.org>
15705 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15706 to show the arg `TIME' instead of `TIMEVAL'.
15708 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15710 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15711 display property strides EOL and includes a newline, as in
15712 longlines-mode. (Bug#9254)
15713 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15714 word-wrap under bidirectional display. (Bug#9224)
15716 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15717 is non-zero, even if the data buffer is NULL. Fixes a crash in
15718 vertical-motion with longlines-mode. (Bug#9254)
15720 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15722 * bidi.c <bidi_cache_total_alloc>: Now static.
15723 (bidi_initialize): Initialize bidi_cache_total_alloc.
15725 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15728 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15729 amount allocated this far in `bidi_cache_total_alloc'.
15730 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15731 non-zero, only free the data buffer without restoring the cache
15732 contents. All callers changed.
15734 * dispextern.h (bidi_unshelve_cache): Update prototype.
15736 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15737 (move_it_in_display_line, move_it_to)
15738 (move_it_vertically_backward, move_it_by_lines): Replace the call
15739 to xfree to an equivalent call to bidi_unshelve_cache.
15740 (move_it_in_display_line_to): Fix logic of returning
15741 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15743 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15745 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15746 came from a string character with a `cursor' property. (Bug#9229)
15748 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15750 * Makefile.in (LIB_PTHREAD): New variable.
15751 (LIBES): Add LIB_PTHREAD (Bug#9216).
15753 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15754 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15756 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15758 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15760 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15762 * xterm.c (x_find_topmost_parent): New function.
15763 (x_set_frame_alpha): Find topmost parent window with
15764 x_find_topmost_parent and set the property there also (bug#9181).
15765 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15767 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15769 * callproc.c (Fcall_process): Avoid vfork clobbering
15770 the local vars buffer, coding_systems, current_dir.
15772 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15774 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15776 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15778 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15779 so that it is not optimized away.
15781 * xdisp.c (compute_display_string_pos): Remove unused local.
15783 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15785 Fix slow cursor motion and scrolling in large buffers with
15786 selective display, like Org Mode buffers. (Bug#9218)
15788 * dispextern.h (struct bidi_it): New member disp_prop_p.
15790 * xdisp.c: Remove one-slot cache of display string positions.
15791 (compute_display_string_pos): Accept an additional argument
15792 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15793 for a display string or property. If found, set DISP_PROP_P
15796 * bidi.c (bidi_fetch_char): Accept an additional argument
15797 DISP_PROP_P, and pass it to compute_display_string_pos.
15798 Only handle text covered by a display string if DISP_PROP_P is returned
15799 non-zero. All callers of bidi_fetch_char changed.
15801 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15803 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15805 2010-12-03 Don March <don@ohspite.net>
15807 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15808 last character M-[char] is translated to ESC [char] (bug#7541).
15810 2011-08-02 Kenichi Handa <handa@m17n.org>
15812 * lisp.h (uniprop_table): Extern it.
15814 * chartab.c (uniprop_table): Make it non-static.
15816 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15818 * xdisp.c (forward_to_next_line_start): Accept additional argument
15819 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15821 (reseat_at_next_visible_line_start): Use the bidi iterator state
15822 returned by forward_to_next_line_start to restore the state of
15823 it->bidi_it after backing up to previous newline. (Bug#9212)
15825 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15827 * regex.c (re_comp): Protoize.
15828 (re_exec): Fix return type.
15829 (regexec): Fix type of `ret'. (Bug#9203)
15831 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15833 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15834 This is needed if max-image-size is a floating-point number.
15836 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15838 * print.c (print_object): Print empty symbol as ##.
15840 * lread.c (read1): Read ## as empty symbol.
15842 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15844 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15845 setting frame foreground color (Bug#9175).
15846 (x_set_background_color): Likewise.
15848 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15849 contents (Bug#9176).
15850 (EmacsTooltip -init): Remove bezels and add shadows to
15853 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15854 or scroll bar (Bug#8470).
15856 * nsfont.m (nsfont_open): Remove assignment to voffset and
15857 unnecessary vars hshink, expand, hd, full_height, min_height.
15858 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15860 * nsterm.h (nsfont_info): Remove voffset field.
15862 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15864 Implement strike-through and overline on NextStep (Bug#8863).
15866 * nsfont.m (nsfont_open): Use underline position provided by font,
15867 instead of hard-coded value of 2.
15868 (nsfont_draw): Call ns_draw_text_decoration instead.
15870 * nsterm.h: Add declaration for ns_draw_text_decoration.
15872 * nsterm.m (ns_draw_text_decoration): New function for drawing
15873 underline, overline, and strike-through.
15874 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15875 ns_draw_text_decoration. Change treatment of cursor drawing to
15876 accommodate underlining, etc.
15878 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15880 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15883 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15885 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15886 Without this fix, if a signal arrives just after memory fills up,
15887 'malloc' might be invoked reentrantly.
15889 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15890 In other words, assume that every image size is allowed, on non-X
15891 hosts. This assumption is probably wrong, but it lets Emacs compile.
15893 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15895 * regex.c (re_iswctype): Convert return values to boolean.
15897 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15899 * xdisp.c (compute_display_string_pos): Don't use cached display
15900 string position if the buffer had its restriction changed.
15903 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15905 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15907 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15909 Integer signedness and overflow and related fixes. (Bug#9079)
15911 * bidi.c: Integer size and overflow fixes.
15912 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15913 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15914 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15915 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15916 (bidi_find_other_level_edge):
15917 Use ptrdiff_t instead of EMACS_INT where either will do.
15918 This works better on 32-bit hosts configured --with-wide-int.
15919 (bidi_cache_ensure_space): Check for size-calculation overflow.
15920 Use % rather than repeated addition, for better worst-case speed.
15921 Don't set bidi_cache_size until after xrealloc returns, because it
15923 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15924 (bidi_cache_ensure_space): Also check that the bidi cache size
15925 does not exceed that of the largest Lisp string or buffer. See Eli
15926 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15928 * alloc.c (__malloc_size_t): Remove.
15929 All uses replaced by size_t. See Andreas Schwab's note
15930 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15932 * image.c: Improve checking for integer overflow.
15933 (check_image_size): Assume that f is nonnull, since
15934 it is always nonnull in practice. This is one less thing to
15935 worry about when checking for integer overflow later.
15936 (x_check_image_size): New function, which checks for integer
15937 overflow issues inside X.
15938 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15939 This removes the need for a memory_full check.
15940 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15941 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15942 (xbm_read_bitmap_data): Change locals back to 'int', since
15943 their values must fit in 'int'.
15944 (xpm_load_image, png_load, tiff_load):
15945 Invoke x_create_x_image_and_pixmap earlier,
15946 to avoid much needless work if the image is too large.
15947 (tiff_load): Treat overly large images as if
15948 x_create_x_image_and_pixmap failed, not as malloc failures.
15949 (gs_load): Use x_check_image_size.
15951 * gtkutil.c: Omit integer casts.
15952 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15953 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15955 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15957 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15958 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15959 would wrongly return t on a 64-bit host.
15961 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15962 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15963 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15964 and therefore cause GCC to emit a bogus diagnostic in some cases.
15966 * image.c: Integer signedness and overflow and related fixes.
15967 This is not an exhaustive set of fixes, but it's time to
15968 record what I've got.
15969 (lookup_pixel_color, check_image_size): Remove redundant decls.
15970 (check_image_size): Don't assume that arbitrary EMACS_INT values
15971 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15972 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15973 (tiff_load, imagemagick_load_image):
15974 Check for overflow in size calculations.
15975 (x_create_x_image_and_pixmap): Remove unnecessary test for
15976 xmalloc returning NULL; that can't happen.
15977 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15978 (xpm_color_bucket): Use better integer hashing function.
15979 (xpm_cache_color): Don't possibly over-allocate memory.
15980 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15981 (gif_memory_source):
15982 Use ptrdiff_t, not int or size_t, to record sizes.
15983 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15984 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15985 either works, as we prefer signed integers.
15986 (tiff_read_from_memory, tiff_write_from_memory):
15987 Return tsize_t, not size_t, since that's what the TIFF API wants.
15988 (tiff_read_from_memory): Don't fail simply because the read would
15989 go past EOF; instead, return a short read.
15990 (tiff_load): Omit no-longer-needed casts.
15991 (Fimagemagick_types): Don't assume size fits into 'int'.
15993 Improve hashing quality when configured --with-wide-int.
15994 * fns.c (hash_string): New function, taken from sxhash_string.
15995 Do not discard information about ASCII character case; this
15996 discarding is no longer needed.
15997 (sxhash-string): Use it. Change sig to match it. Caller changed.
15998 * lisp.h: Declare it.
15999 * lread.c (hash_string): Remove, since we now use fns.c's version.
16000 The fns.c version returns a wider integer if --with-wide-int is
16001 specified, so this should help the quality of the hashing a bit.
16003 * emacs.c: Integer overflow minor fix.
16004 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16005 Define only if GNU_LINUX.
16006 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16008 * dispnew.c: Integer signedness and overflow fixes.
16009 Remove unnecessary forward decls, that were a maintenance hassle.
16010 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16012 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16013 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16014 (prepare_desired_row, line_draw_cost):
16015 Use int, not unsigned, where either works.
16016 (save_current_matrix, restore_current_matrix):
16017 Use ptrdiff_t, not size_t, where either works.
16018 (init_display): Check for overflow more accurately, and without
16019 relying on undefined behavior.
16021 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16022 Remove, replacing with the new symbols in lisp.h. All uses changed.
16023 * fileio.c (make_temp_name):
16024 * filelock.c (lock_file_1, lock_file):
16025 * xdisp.c (message_dolog):
16026 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16027 Use pMd etc. instead.
16028 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16029 replacing the pWIDE etc. symbols removed from editfns.c.
16031 * keyboard.h (num_input_events): Now uintmax_t.
16032 This is (very slightly) less likely to mess up due to wraparound.
16035 * buffer.c: Integer signedness fixes.
16036 (alloc_buffer_text, enlarge_buffer_text):
16037 Use ptrdiff_t rather than size_t when either will do, as we prefer
16040 * alloc.c: Integer signedness and overflow fixes.
16041 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16042 (__malloc_size_t): Default to size_t, not to int.
16043 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16044 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16045 Prefer ptrdiff_t to size_t when either would do, as we prefer
16047 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16048 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16049 Now const. Initialize with values that are in range even if char
16051 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16052 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16053 These functions do the right thing with sizes > 2**32.
16054 (check_depth): Now ptrdiff_t, not int.
16055 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16056 Adjust to new way of storing sizes. Check for size overflow bugs
16058 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16059 slightly wrong anyway, as it missed one instance of
16060 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16061 (refill_memory_reserve): Omit needless cast to size_t.
16062 (mark_object_loop_halt): Mark as externally visible.
16064 * xselect.c: Integer signedness and overflow fixes.
16065 (Fx_register_dnd_atom, x_handle_dnd_message):
16066 Use ptrdiff_t, not size_t, since we prefer signed.
16067 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16068 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16069 x_dnd_atoms_size and x_dnd_atoms_length.
16071 * doprnt.c: Prefer signed to unsigned when either works.
16073 * doprnt.c (doprnt):
16075 * xdisp.c (vmessage):
16076 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16077 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16078 prefer signed arithmetic to avoid comparison confusion.
16079 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16080 but is a bit tricky.
16082 Assume freestanding C89 headers, string.h, stdlib.h.
16083 * data.c, doprnt.c, floatfns.c, print.c:
16084 Include float.h unconditionally.
16085 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16086 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16087 * regex.c: Likewise for stddef.h, string.h.
16088 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16089 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16090 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16091 (STDC_HEADERS): Remove obsolete defines.
16092 * sysdep.c: Include limits.h unconditionally.
16094 Assume support for memcmp, memcpy, memmove, memset.
16095 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16096 * regex.c (memcmp, memcpy):
16097 Remove; we assume C89 now.
16099 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16100 (__malloc_safe_bcopy): Remove; no longer needed.
16102 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16103 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16104 well either way, and we prefer signed to unsigned.
16106 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16108 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16109 closes the connection while we're reading (bug#9182).
16111 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16113 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16114 are specified (Bug#9168).
16116 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16118 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16119 Found by GCC static checking and --with-wide-int on a 32-bit host.
16121 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16123 * xdisp.c (compute_display_string_pos): Fix logic of caching
16124 previous display string position. Initialize cached_prev_pos to
16125 -1. Fixes slow-down at the beginning of a buffer.
16127 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16129 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16130 for attrs[LFACE_FONTSET_INDEX].
16132 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16134 * xml.c (parse_region): Remove unused local
16135 that was recently introduced.
16137 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16139 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16140 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16142 * xdisp.c (move_it_in_display_line_to): Record the best matching
16143 position for TO_CHARPOS while scanning the line, and restore it on
16144 exit if none of the characters scanned was an exact match.
16145 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16146 when exact match is impossible due to invisible text, and the
16147 lines are truncated.
16149 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16151 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16154 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16156 Fix a significant slow-down of cursor motion with C-n, C-p,
16157 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16158 auto-repeat under bidi redisplay in fontified buffers.
16159 * xdisp.c (compute_stop_pos_backwards): New function.
16160 (next_element_from_buffer): Call compute_stop_pos_backwards to
16161 find a suitable prev_stop when we find ourselves before
16163 (reseat): Don't look for prev_stop, as that could mean a very long
16165 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16166 <cached_disp_overlay_modiff>: Cache for last found display string
16168 (compute_display_string_pos): Return the cached position if asked
16169 about the same buffer in the same area of character positions, and
16170 the buffer wasn't changed since the time the display string
16171 position was cached.
16173 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16175 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16176 is an integer, which is important for empty lines. (Bug#9149)
16178 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16180 * frame.c (Fmodify_frame_parameters): In tty case, update the
16181 default face if necessary (Bug#4238).
16183 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16185 * editfns.c (Fstring_to_char): No need to explain what a character
16186 is in the docstring (Bug#6576).
16188 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16190 * xml.c (parse_region): Make sure we always return a tree.
16192 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16194 * xml.c (parse_region): If a document contains only comments,
16197 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16199 * xml.c (make_dom): Return comments, too.
16201 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16204 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16205 and the surrounding thread.
16206 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16207 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16208 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16210 * s/openbsd.h (BROKEN_SIGIO): Define.
16211 * unexelf.c (unexec) [__OpenBSD__]:
16212 Don't update the .mdebug section of the Alpha COFF symbol table.
16214 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16216 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16219 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16221 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16222 This fixes some race conditions on the permissions of any newly
16225 * alloc.c (valid_pointer_p): Use pipe, not open.
16226 This fixes some permissions issues when debugging.
16228 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16229 If fchown fails to set both uid and gid, try to set just gid,
16230 as that is sometimes allowed. Adjust the file's mode to eliminate
16231 setuid or setgid bits that are inappropriate if fchown fails.
16233 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16235 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16236 to compare Lisp_Objects.
16237 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16238 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16239 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16241 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16243 * lread.c (read_integer): Unread even EOF character.
16244 (read1): Likewise. Properly record start position of symbol.
16246 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16247 symbol character follows.
16249 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16251 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16252 This works around a problem with the previous change to Fcopy_file.
16253 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16254 and without this change, GCC might complain about discarding
16255 fchown's return value.
16257 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16259 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16261 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16263 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16265 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16267 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16268 it's used from the C level.
16270 * process.c: Use the same condition for POLL_FOR_INPUT in both
16271 keyboard.c and process.c (bug#1858).
16273 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16275 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16276 (Fgnutls_boot): Use it.
16278 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16280 * doc.c (Fsubstitute_command_keys): Revert last change.
16282 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16284 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16285 quotes the next character, and doesn't affect other longer
16286 sequences (bug#8935).
16288 * lread.c (syms_of_lread): Clarify that is isn't only
16289 `eval-buffer' and `eval-defun' that's affected by
16290 `lexical-binding' (bug#8460).
16292 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16294 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16295 bidi redisplay when a line includes both an image and is truncated.
16297 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16299 Fix minor problems found by static checking.
16300 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16301 (elsz): Now a signed constant, not a size_t var. We prefer signed
16302 types to unsigned, to avoid integer comparison confusion. Without
16303 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16304 "cannot optimize loop, the loop counter may overflow", a symptom
16306 * indent.c (Fvertical_motion): Mark locals as initialized.
16307 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16309 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16311 * search.c (Fre_search_backward): Mention `case-fold-search' in
16312 all the re_search_* functions (bug#8138).
16314 * keyboard.c (Fopen_dribble_file): Document when the file is

16319 * bidi.c (bidi_dump_cached_states): Fix format of displaying
16322 Support bidi reordering of display and overlay strings.

16324 (compute_display_string_end): Accept additional argument STRING.
16325 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
16326 (reseat_to_string): Initialize bidi_it->string.s and
16327 bidi_it->string.schars.
16328 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16329 NULL (avoids a crash in bidi_paragraph_init).
16330 Initialize itb.string.lstring.
16331 (init_iterator): Call bidi_init_it only of a valid
16332 buffer position was specified. Initialize paragraph_embedding to
16334 (reseat_to_string): Initialize the bidi iterator.
16335 (display_string): If we need to ignore text properties of
16336 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16337 original value of -1 will not work with bidi.)
16338 (compute_display_string_pos): First arg is now struct
16339 `text_pos *'; all callers changed. Support display properties on
16341 (compute_display_string_end): Support display properties on Lisp
16343 (init_iterator, reseat_1, reseat_to_string): Initialize the
16344 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16345 when iterating on a string not from display properties).
16346 (compute_display_string_pos, compute_display_string_end):
16347 Fix calculation of the object to scan. Fixes an error when using
16349 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16350 base_level_stop; instead, set base_level_stop to BEGV.
16351 Fixes crashes in vertical-motion.
16352 (next_element_from_buffer): Improve commentary for when
16353 the iterator is before prev_stop.
16354 (init_iterator): Initialize bidi_p from the default value of
16355 bidi-display-reordering, not from buffer-local value. Use the
16356 buffer-local value only if initializing for buffer iteration.
16357 (handle_invisible_prop): Support invisible properties on strings
16358 that are being bidi-reordered.
16359 (set_iterator_to_next): Support bidi reordering of C strings and
16361 (next_element_from_string): Support bidi reordering of Lisp
16363 (handle_stop_backwards): Support Lisp strings as well.
16364 (display_string): Support display of R2L glyph rows.
16365 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16366 (init_iterator): Don't initialize it->bidi_p for strings
16368 (reseat_to_string): Initialize it->bidi_p for strings here.
16369 (next_element_from_string, next_element_from_c_string)
16370 (next_element_from_buffer): Add xassert's for correspondence
16371 between IT's object being iterated and it->bidi_it.string
16373 (face_before_or_after_it_pos): Support bidi iteration.
16374 (next_element_from_c_string): Handle the case of the first string
16375 character that is not the first one in the visual order.
16376 (get_visually_first_element): New function, refactored from common
16377 parts of next_element_from_buffer, next_element_from_string, and
16378 next_element_from_c_string.
16379 (tool_bar_lines_needed, redisplay_tool_bar)
16380 (display_menu_bar): Force left-to-right direction. Add a FIXME
16381 comment for making that be controlled by a user option.
16382 (push_it, pop_it): Save and restore the state of the
16383 bidi iterator. Save and restore the bidi_p flag.
16384 (pop_it): Iterate out of display property for string iteration as
16386 (iterate_out_of_display_property): Support iteration over strings.
16387 (handle_single_display_spec): Set up it->bidi_it for iteration
16388 over a display string, and call bidi_init_it.
16389 (handle_single_display_spec, next_overlay_string)
16390 (get_overlay_strings_1, push_display_prop): Set up the bidi
16391 iterator for displaying display or overlay strings.
16392 (forward_to_next_line_start): Don't use the shortcut if
16394 (back_to_previous_visible_line_start): If handle_display_prop
16395 pushed the iterator stack, restore the internal state of the bidi
16396 iterator by calling bidi_pop_it same number of times.
16397 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16398 and we are bidi-iterating, don't decrement the iterator position;
16399 instead, set the first_elt flag in the bidi iterator, to produce
16401 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16402 (push_display_prop): xassert that we are iterating a buffer.
16403 (push_it, pop_it): Save and restore paragraph_embedding member.
16404 (handle_single_display_spec, next_overlay_string)
16405 (get_overlay_strings_1, reseat_1, reseat_to_string)
16406 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16407 correctly. Don't assume unibyte strings are not bidi-reordered.
16408 (compute_display_string_pos)
16409 (compute_display_string_end): Fix handling the case of C string.
16410 (push_it, pop_it): Save and restore from_disp_prop_p.
16411 (handle_single_display_spec, push_display_prop): Set the
16412 from_disp_prop_p flag.
16413 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
16414 (pop_it): Call iterate_out_of_display_property only if we are
16415 popping after iteration over a string that came from a display
16416 property. Fix a typo in popping stretch info. Add an assertion
16417 for verifying that the iterator position is in sync with the bidi
16419 (handle_single_display_spec, get_overlay_strings_1)
16420 (push_display_prop): Fix initialization of paragraph direction for
16421 string when that of the parent object is not yet determined.
16422 (reseat_1): Call bidi_init_it to resync the bidi
16423 iterator with IT's position. (Bug#7616)
16424 (find_row_edges): If ROW->start.pos gives position
16425 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
16426 (handle_stop, back_to_previous_visible_line_start, reseat_1):
16427 Reset the from_disp_prop_p flag.
16428 (SAVE_IT, RESTORE_IT): New macros.
16429 (pos_visible_p, face_before_or_after_it_pos)
16430 (back_to_previous_visible_line_start)
16431 (move_it_in_display_line_to, move_it_in_display_line)
16432 (move_it_to, move_it_vertically_backward, move_it_by_lines)
16433 (try_scrolling, redisplay_window, display_line): Use them when
16434 saving a temporary copy of the iterator and restoring it back.
16435 (back_to_previous_visible_line_start, reseat_1)
16436 (init_iterator): Empty the bidi cache "stack".
16437 (move_it_in_display_line_to): If iterator ended up at
16438 EOL, but we never saw any buffer positions smaller than
16439 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16440 motion in bidi-reordered lines.
16441 (move_it_in_display_line_to): Record prev_method and prev_pos
16442 immediately before the call to set_iterator_to_next. Fixes cursor
16443 motion in bidi-reordered lines with stretch glyphs and strings
16444 displayed in margins. (Bug#8133) (Bug#8867)
16445 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16447 (pos_visible_p): Support positions in bidi-reordered lines.
16448 Save and restore bidi cache.
16450 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16451 (bidi_paragraph_info): Delete unused struct.
16452 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
16453 (bidi_cache_start): New variable.
16454 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
16456 (bidi_cache_fetch_state, bidi_cache_search)
16457 (bidi_cache_find_level_change, bidi_cache_iterator_state)
16458 (bidi_cache_find, bidi_peek_at_next_level)

16462 (bidi_fetch_char): Accept new argument STRING; all callers
16463 changed. Support iteration over a string. Support strings with
16464 display properties. Support unibyte strings. Fix the type of
16465 `len' according to what STRING_CHAR_AND_LENGTH expects.
16466 (bidi_paragraph_init, bidi_resolve_explicit_1)
16467 (bidi_resolve_explicit, bidi_resolve_weak)
16468 (bidi_level_of_next_char, bidi_move_to_visually_next):
16469 Support iteration over a string.
16470 (bidi_set_sor_type, bidi_resolve_explicit_1)
16471 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16472 can now be zero (for strings); special values 0 and -1 were
16473 changed to -1 and -2, respectively.

16561 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16563 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16564 The old code sometimes used this field without initializing it.
16566 * alloc.c (gc_sweep): Don't read past end of array.
16567 In theory, the old code could also have corrupted Emacs internals,
16568 though it'd be very unlikely.

16572 * character.c (Fcharacterp): Don't advertise optional ignored

16671 Use pthread_sigmask, not sigprocmask (Bug#9010).
16672 sigprocmask is portable only for single-threaded applications, and
16673 Emacs can be multi-threaded when it uses GTK.

16711 variable firstTime not needed on OSX >= 10.6.

16831 (clone_per_buffer_values): Don't assume that
16832 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
16833 This isn't true in general, and it's particularly not true
16834 if Emacs is configured with --with-wide-int.
16835 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16836 New macros, used in the buffer.c change.

16872 Random fixes. E.g., (random) never returned negative values.
16873 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16874 subseconds part to the entropy, as that's a bit more random.
16875 Prefer signed to unsigned, since the signedness doesn't matter and
16876 in general we prefer signed. When given a limit, use a
16877 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16878 latter isn't right if USE_2_TAGS_FOR_INTS.
16879 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16880 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16890 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
16892 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16893 This is more efficient than Ffile_directory_p and avoids a minor race.
16895 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16897 * buffer.c (Foverlay_put): Say what the return value is
16900 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16901 is a directory before asking whether to use the file name
16903 (barf_or_query_if_file_exists): Make the "File is a directory"
16904 error be more correct.
16906 * fns.c (Frequire): Remove the mention of the .gz files, since
16907 that's installation-specific, but keep the mention of
16908 `get-load-suffixes'.
16910 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
16912 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17025 * eval.c (struct backtrace): Simplify and port the data structure.
17026 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17027 signed bit field, as this assumption is not portable and it makes
17028 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17029 "char debug_on_exit : 1" as this is not portable either; instead,
17030 use the portable "unsigned int debug_on_exit : 1". Remove unused
17031 member evalargs. Remove obsolete comments about cc bombing out.

17267 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17268 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17269 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17270 since we're not interested in debugging glyphs with old libraries.
17271 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17272 GCC 4.6.0's static checking.

17359 Reformulate so as not to need the command string.
17360 Invoke gzip -cd rather than gunzip, as it's more portable.
17361 (lock_info_type, lock_file_1, lock_file):
17362 Don't assume pid_t and time_t fit in unsigned long.
17363 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17364 (current_lock_owner): Prefer signed type for sizes.
17365 Use memcpy, not strncpy, where memcpy is what is really wanted.
17366 Don't assume (via atoi) that time_t and pid_t fit in int.
17367 Check for time_t and/or pid_t out of range, e.g., via a network share.
17368 Don't alloca where an auto var works fine.
17370 * fileio.c: Fix some integer overflow issues.
17371 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17372 Don't assume string length fits in int.
17373 (directory_file_name): Don't assume string length fits in long.
17374 (make_temp_name): Don't assume pid fits in int, or that its print
17375 length is less than 20.
17377 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17379 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17381 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17383 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17384 We prefer signed integers, even for size calculations.
17386 * emacs.c: Don't assume string length fits in 'int'.
17387 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17388 (main): Don't invoke strlen when not needed.
17390 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17391 (XD_DEBUG_MESSAGE): Don't waste a byte.
17393 * callproc.c (getenv_internal_1, getenv_internal)
17394 (Fgetenv_internal):
17395 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17397 * lread.c (invalid_syntax): Omit length argument.
17398 All uses changed. This doesn't fix a bug, but it simplifies the
17399 code away from its former Hollerith-constant appearance, and it's
17400 one less 'int' to worry about when looking at integer-overflow issues.
17401 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17403 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17404 This didn't break anything, but it didn't help either.
17405 It's confusing to put a bogus integer in a place where the actual
17406 value does not matter.
17407 (LIST_END_P): Remove unused macro and its bogus comment.
17408 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17410 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17411 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17413 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17414 We prefer signed types, and the value cannot exceed the EMACS_INT
17415 range anyway (because otherwise the length would not be representable).
17416 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17417 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17418 This avoids a GCC warning when WIDE_EMACS_INT.
17420 * indent.c (sane_tab_width): New function.
17421 (current_column, scan_for_column, Findent_to, position_indentation)
17422 (compute_motion): Use it. This is just for clarity.
17423 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17425 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17427 * lisp.h (lint_assume): New macro.
17428 * composite.c (composition_gstring_put_cache):
17429 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17431 * editfns.c, insdel.c:
17432 Omit unnecessary forward decls, to simplify future changes.
17434 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17436 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17438 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17439 Use much-faster test for byte-length change.
17440 Don't assume string byte-length fits in 'int'.
17441 Check that character arg fits in 'int'.
17442 (mapcar1): Declare byte as byte, for clarity.
17444 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17446 * fns.c (concat): Catch string overflow earlier.
17447 Do not rely on integer wraparound.
17449 * dispextern.h (struct it.overlay_strings_charpos)
17450 (struct it.selective): Now EMACS_INT, not int.
17451 * xdisp.c (forward_to_next_line_start)
17452 (back_to_previous_visible_line_start)
17453 (reseat_at_next_visible_line_start, next_element_from_buffer):
17454 Don't arbitrarily truncate the value of 'selective' to int.
17456 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17458 * composite.c: Don't truncate sizes to 'int'.
17459 (composition_gstring_p, composition_reseat_it)
17460 (composition_adjust_point): Use EMACS_INT, not int.
17461 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17462 not EMACS_UINT, for indexes.
17464 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17466 * buffer.c: Include <verify.h>.
17467 (struct sortvec.priority, struct sortstr.priority):
17468 Now EMACS_INT, not int.
17469 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17470 (struct sortstr.size, record_overlay_string)
17471 (struct sortstrlist.size, struct sortlist.used):
17472 Don't truncate size to int.
17473 (record_overlay_string): Check for size-calculation overflow.
17474 (init_buffer_once): Check at compile-time, not run-time.
17476 2011-06-22 Jim Meyering <meyering@redhat.com>
17478 Don't leak an XBM-image-sized buffer
17479 * image.c (xbm_load): Free the image buffer after using it.
17481 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17484 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17485 that Sun C diagnosed.
17486 * fns.c (secure_hash): Fix pointer signedness issue.
17487 * intervals.c (static_offset_intervals): New function.
17488 (offset_intervals): Use it.
17490 2011-06-21 Leo Liu <sdl.web@gmail.com>
17493 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17496 * fns.c (secure_hash): Rename from crypto_hash_function and change
17497 the first arg to accept symbols.
17498 (Fsecure_hash): New primitive.
17499 (syms_of_fns): New symbols.
17501 2011-06-20 Deniz Dogan <deniz@dogan.se>
17503 * process.c (Fset_process_buffer): Clarify return value in
17506 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17508 * dispnew.c (add_window_display_history): Use BVAR.
17510 * xdisp.c (debug_method_add): Use BVAR.
17511 (check_window_end, dump_glyph_matrix, dump_glyph)
17512 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17514 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17517 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17518 check till after the cache is created in init_frame_faces.
17520 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17522 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17524 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17526 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17527 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17528 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17530 Improve buffer-overflow checking (Bug#8873).
17531 * fileio.c (Finsert_file_contents):
17532 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17533 Remove the old (too-loose) buffer overflow checks.
17534 They weren't needed, since make_gap checks for buffer overflow.
17535 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17536 The old code merely checked for Emacs fixnum overflow, and relied
17537 on undefined (wraparound) behavior. The new code avoids undefined
17538 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17540 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17541 Tune. Don't use wider integers than needed. Don't use alloca.
17542 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17544 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17546 * insdel.c, lisp.h (buffer_overflow): New function.
17547 (insert_from_buffer_1, replace_range, replace_range_2):
17548 * insdel.c (make_gap_larger):
17549 * editfns.c (Finsert_char):
17550 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17552 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17554 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17556 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17558 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17559 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17561 * fileio.c: Don't assume EMACS_INT fits in off_t.
17562 (emacs_lseek): New static function.
17563 (Finsert_file_contents, Fwrite_region): Use it.
17564 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17566 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17568 * fns.c: Don't overflow int when computing a list length.
17569 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17570 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17571 truncation on 64-bit hosts. Check for QUIT every
17572 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17573 faster and is responsive enough.
17574 (Flength): Report an error instead of overflowing an integer.
17575 (Fsafe_length): Return a float if the value is not representable
17576 as a fixnum. This shouldn't happen except in contrived situations.
17577 (Fnthcdr, Fsort): Don't assume list length fits in int.
17578 (Fcopy_sequence): Don't assume vector length fits in int.
17580 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17581 (header_size, word_size): New constants.
17582 (allocate_vectorlike): Don't check size overflow here.
17583 (allocate_vector): Check it here instead, since this is the only
17584 caller of allocate_vectorlike that could cause overflow.
17585 Check that the new vector's length is representable as a fixnum.
17587 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17588 The previous code was bogus. For example, next_almost_prime (32)
17589 returned 39, which is undesirable as it is a multiple of 3; and
17590 next_almost_prime (24) returned 25, which is a multiple of 5 so
17591 why was the code bothering to check for multiples of 7?
17593 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17595 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17597 Variadic C functions now count arguments with ptrdiff_t.
17598 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17599 Back then I didn't know that the Emacs coding style prefers signed int.
17600 Also, in the meantime I found a few more instances where arguments
17601 were being counted with int, which may truncate counts on 64-bit
17602 machines, or EMACS_INT, which may be unnecessarily wide.
17603 * lisp.h (struct Lisp_Subr.function.aMANY)
17604 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17605 Arg counts are now ptrdiff_t, not size_t.
17606 All variadic functions and their callers changed accordingly.
17607 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17608 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17609 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17610 * callint.c (Fcall_interactively): Check arg count for overflow,
17611 to avoid potential buffer overrun. Use signed char, not 'int',
17612 for 'varies' array, so that we needn't bother to check its size
17613 calculation for overflow.
17614 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17615 * eval.c (apply_lambda):
17616 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17617 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17618 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17620 * callint.c (Fcall_interactively): Don't use index var as event count.
17622 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17623 * mem-limits.h (SIZE): Remove; no longer used.
17625 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17627 Remove unnecessary casts.
17628 * xterm.c (x_term_init):
17629 * xfns.c (x_set_border_pixel):
17630 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17631 These aren't needed now that we assume ANSI C.
17633 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17634 It's more likely to cause problems (due to unsigned overflow)
17637 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17639 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17641 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17643 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17645 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17647 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17649 GLYPH_CODE_FACE returns EMACS_INT, not int.
17650 * dispextern.h (merge_faces):
17651 * xfaces.c (merge_faces):
17652 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17653 Don't assume EMACS_INT fits in int.
17655 * character.h (CHAR_VALID_P): Remove unused parameter.
17656 * fontset.c, lisp.h, xdisp.c: All uses changed.
17658 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17660 * fns.c (concat): Minor tuning based on overflow analysis.
17661 This doesn't fix any bugs. Use int to hold character, instead
17662 of constantly refetching from Emacs object. Use XFASTINT, not
17663 XINT, for value known to be a character. Don't bother comparing
17664 a single byte to 0400, as it's always less.
17666 * floatfns.c (Fexpt):
17667 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17669 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17672 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17674 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17675 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17676 incorrectly succeed when S was a string, because 4294967386 was
17677 truncated before it was used.
17679 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17680 Otherwise, an out-of-range integer could cause undefined behavior
17683 * composite.c: Use int, not EMACS_INT, for characters.
17684 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17685 EMACS_INT, for values that are known to be in character range.
17686 This doesn't fix any bugs but is the usual style inside Emacs and
17687 may generate better code on 32-bit machines.
17689 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17690 This is for reasons similar to the recent CHAR_STRING fix.
17691 * charset.c (Fencode_char): Check that character arg is actually
17692 a character. Pass an int to ENCODE_CHAR.
17693 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17694 wider than 'int', as a compile-time check to prevent future regressions
17697 * character.c (char_string): Remove unnecessary casts.
17699 Make sure a 64-bit char is never passed to CHAR_STRING.
17700 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17701 by silently ignoring the top 32 bits, allowing some values
17702 that were far too large to be valid characters.
17703 * character.h: Include <verify.h>.
17704 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17705 arguments are no wider than unsigned, as a compile-time check
17706 to prevent future regressions in this area.
17708 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17709 (Fsubst_char_in_region):
17711 * xdisp.c (decode_mode_spec_coding):
17712 Adjust to CHAR_STRING's new requirement.
17713 * editfns.c (Finsert_char, Fsubst_char_in_region):
17714 * fns.c (concat): Check that character args are actually
17715 characters. Without this test, these functions did the wrong
17716 thing with wildly out-of-range values on 64-bit hosts.
17718 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17719 These casts should not be needed on 32-bit hosts, either.
17720 * keyboard.c (read_char):
17721 * lread.c (Fload): Remove casts to unsigned.
17723 * lisp.h (UNSIGNED_CMP): New macro.
17724 This fixes comparison bugs on 64-bit hosts.
17725 (ASCII_CHAR_P): Use it.
17726 * casefiddle.c (casify_object):
17727 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17728 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17729 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17730 * dispextern.h (FACE_FROM_ID):
17731 * keyboard.c (read_char): Use UNSIGNED_CMP.
17733 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17734 not to EMACS_INT, to avoid GCC warning.
17736 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17738 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17739 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17740 isn't needed on 32-bit machines.
17742 * buffer.c (Fgenerate_new_buffer_name):
17743 Use EMACS_INT for count, not int.
17744 (advance_to_char_boundary): Return EMACS_INT, not int.
17746 * data.c (Qcompiled_function): Now static.
17748 * window.c (window_body_lines): Now static.
17750 * image.c (gif_load): Rename local to avoid shadowing.
17752 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17753 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17754 * alloc.c (make_save_value): Integer argument is now of type
17755 ptrdiff_t, not int.
17756 (mark_object): Use ptrdiff_t, not int.
17757 * lisp.h (pD): New macro.
17758 * print.c (print_object): Use it.
17760 * alloc.c: Use EMACS_INT, not int, to count objects.
17761 (total_conses, total_markers, total_symbols, total_vector_size)
17762 (total_free_conses, total_free_markers, total_free_symbols)
17763 (total_free_floats, total_floats, total_free_intervals)
17764 (total_intervals, total_strings, total_free_strings):
17765 Now EMACS_INT, not int. All uses changed.
17766 (Fgarbage_collect): Compute overall total using a double, so that
17767 integer overflow is less likely to be a problem. Check for overflow
17768 when converting back to an integer.
17769 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17770 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17771 These were 'int' variables that could overflow on 64-bit hosts;
17772 they were never used, so remove them instead of repairing them.
17773 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17774 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17775 Previously, this ceilinged at INT_MAX, but that doesn't work on
17777 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17779 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17780 (allocate_vectorlike): Check for ptrdiff_t overflow.
17781 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17782 when a (possibly-narrower) signed value would do just as well.
17783 We prefer using signed arithmetic, to avoid comparison confusion.
17785 * alloc.c: Catch some string size overflows that we were missing.
17786 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17787 for convenience in STRING_BYTES_MAX.
17788 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17789 The definition here is exact; the one in lisp.h was approximate.
17790 (allocate_string_data): Check for string overflow. This catches
17791 some instances we weren't catching before. Also, it catches
17792 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17793 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17794 and ptrdiff_t and EMACS_INT are both 64 bits.
17796 * character.c, coding.c, doprnt.c, editfns.c, eval.c:

18240 Minor fixes for signed vs unsigned integers.
18241 * character.h (MAYBE_UNIFY_CHAR):
18242 * charset.c (maybe_unify_char):
18243 * keyboard.c (read_char, reorder_modifiers):
18244 XINT -> XFASTINT, since the integer must be nonnegative.
18245 * ftfont.c (ftfont_spec_pattern):
18246 * keymap.c (access_keymap, silly_event_symbol_error):
18247 XUINT -> XFASTINT, since the integer must be nonnegative.
18248 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
18249 since it makes no difference and we prefer signed.
18250 * keyboard.c (record_char): Use XUINT when all the neighbors do.
18251 (access_keymap): NATNUMP -> INTEGERP, since the integer must be
18254 2011-06-06 Stefan Monnier <monnier@iro.umontreal.ca>

18294 (Fwindow_minibuffer_p): Move up in code and simplify.
18295 (Fset_frame_selected_window): Move here from frame.c.
18297 (Fselected_window, select_window, Fselect_window): Move up in
18298 code. Minor doc-string fixes.
18300 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
18302 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18303 Do not assume that spare memory exists; that assumption is valid
18304 only if SYSTEM_MALLOC.
18305 (LARGE_REQUEST): New macro, so that the issue of large requests
18306 is separated from the issue of spare memory.
18308 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
18310 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

18335 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
18336 New error handlers.
18337 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
18338 Obey Vx_select_enable_clipboard_manager. Catch errors in
18339 x_clipboard_manager_save (Bug#8779).
18340 (Vx_select_enable_clipboard_manager): New variable.
18341 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18343 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18345 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18347 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18349 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18350 in the current matrix if keep_current_p is non-zero.

18354 * bidi.c (bidi_level_of_next_char): Fix last change.
18356 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18358 Support bidi reordering of text covered by display properties.
18360 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18361 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18362 (bidi_cache_search, bidi_cache_iterator_state)
18363 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18364 (bidi_level_of_next_char, bidi_move_to_visually_next):
18365 Support character positions inside a run of characters covered by a
18367 (bidi_paragraph_init, bidi_resolve_explicit_1)
18368 (bidi_level_of_next_char): Call bidi_fetch_char and
18369 bidi_fetch_char_advance instead of FETCH_CHAR and
18370 FETCH_CHAR_ADVANCE.

18372 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18374 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18375 instead of using explicit *_CHAR codes.
18376 (bidi_resolve_explicit, bidi_resolve_weak):
18377 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18378 bidirectional text is supported only in multibyte buffers.
18379 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18380 it to initialize the frame_window_p member of struct bidi_it.
18381 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18382 (bidi_resolve_explicit, bidi_resolve_weak)

18384 bidi_it->nchars is non-positive.
18385 (bidi_level_of_next_char): Don't try to lookup the cache for the
18386 next/previous character if nothing is cached there yet, or if we
18387 were just reseat()'ed to a new position.
18389 * xdisp.c (set_cursor_from_row): Set start and stop points
18390 according to the row's direction when priming the loop that looks
18391 for the glyph on which to display cursor.
18392 (single_display_spec_intangible_p): Function deleted.
18393 (display_prop_intangible_p): Reimplement to call
18394 handle_display_spec instead of single_display_spec_intangible_p.
18395 Accept 3 additional arguments needed by handle_display_spec.
18396 This fixes incorrect cursor motion across display property with complex
18397 values: lists, `(when COND...)' forms, etc.
18398 (single_display_spec_string_p): Support property values that are
18399 lists with the argument STRING its top-level element.
18400 (display_prop_string_p): Fix the condition for processing a
18401 property that is a list to be consistent with handle_display_spec.
18402 (handle_display_spec): New function, refactored from the
18403 last portion of handle_display_prop.
18404 (compute_display_string_pos): Accept additional argument
18405 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18406 value of a `display' property is a "replacing spec".
18407 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18408 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18409 the display property, but just return a value indicating whether
18410 the display property will replace the characters it covers.
18411 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18412 frame_window_p members of struct bidi_it.
18413 (compute_display_string_pos, compute_display_string_end):
18415 (push_it): Accept second argument POSITION, where pop_it should
18416 jump to continue iteration.
18417 (reseat_1): Initialize bidi_it.disp_pos.
18419 * keyboard.c (adjust_point_for_property): Adjust the call to
18420 display_prop_intangible_p to its new signature.
18422 * dispextern.h (struct bidi_it): New member frame_window_p.
18423 (bidi_init_it): Update prototypes.
18424 (display_prop_intangible_p): Update prototype.
18425 (compute_display_string_pos, compute_display_string_end):
18426 Declare prototypes.
18427 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18430 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18432 Malloc failure behavior now depends on size of allocation.
18433 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18434 * lisp.h: Change signatures accordingly.
18435 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18436 All callers changed. (Bug#8762)
18438 * gnutls.c: Use Emacs's memory allocators.
18439 Without this change, the gnutls library would invoke malloc etc.
18440 directly, which causes problems on non-SYNC_INPUT hosts, and which
18441 runs afoul of improving memory_full behavior. (Bug#8761)
18442 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18443 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18444 xfree instead of the default malloc, realloc, free.
18445 (Fgnutls_boot): No need to check for memory allocation failure,
18446 since xmalloc does that for us.
18448 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18449 * category.c (hash_get_category_set):
18450 * ccl.c (ccl_driver):
18451 * charset.c (Fdefine_charset_internal):

18462 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18463 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18464 * image.c (make_image, search_image_cache, lookup_image)
18465 (xpm_put_color_table_h):
18466 * lisp.h (struct Lisp_Hash_Table):
18467 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18468 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18469 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18470 * alloc.c (allocate_vectorlike):
18471 Check for overflow in vector size calculations.
18472 * ccl.c (ccl_driver):
18473 Check for overflow when converting EMACS_INT to int.
18474 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18475 need to be updated by these changes.
18476 * fns.c (make_hash_table, maybe_resize_hash_table):
18477 Check for integer overflow with large hash tables.
18478 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18479 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18480 (SXHASH_REDUCE): New macro.
18481 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18482 Use it instead of discarding useful hash info with large hash values.
18483 (sxhash_float): New function.
18484 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18485 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18486 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18487 Rewrite to use FIXNUM_BITS, as this simplifies things.
18488 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18489 Adjust signatures to match updated version of code.
18490 (consing_since_gc): Now EMACS_INT, since a single hash table can
18491 use more than INT_MAX bytes.
18493 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18495 Make it possible to build with GCC-4.6+ -O2 -flto.
18497 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18499 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18501 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18502 Call minibuffer-inactive-mode.
18504 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18506 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18507 Update dependencies.
18509 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18511 * data.c (init_data): Remove code for UTS, this system is not
18514 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18516 Don't force ./temacs to start in terminal mode.
18518 * frame.c (make_initial_frame): Initialize faces in all cases, not
18519 only when CANNOT_DUMP is defined.
18520 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18522 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18524 * dispnew.c (add_window_display_history): Use const for the string
18525 pointer. Remove declaration, not needed.
18527 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18529 Use 'inline', not 'INLINE'.
18530 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18531 * alloc.c, fontset.c (INLINE): Remove.
18532 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18533 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18534 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18535 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18536 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18538 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18540 Make it possible to run ./temacs.
18542 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18543 syms_of_callproc does the same thing. Remove test for
18544 "initialized", do it in the caller.
18545 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18547 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18549 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18550 (read_minibuf): Use get_minibuffer.
18551 (syms_of_minibuf): Use DEFSYM.
18552 (Qmetadata): New var.
18553 * data.c (Qbuffer): Don't make it static.
18554 (syms_of_data): Use DEFSYM.
18556 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18558 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18559 (CCL_CODE_MIN): New macro.
18561 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18563 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18565 * eval.c (Qdebug): Now static.
18566 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18567 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18568 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18570 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18572 * image.c: Various fixes to ImageMagick code comments.
18573 (Fimagemagick_types): Doc fix.
18575 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18577 Minor fixes prompted by GCC 4.6.0 warnings.
18579 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18581 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18582 (x_clipboard_manager_save_all): Move extern decl to ...
18583 * xterm.h: ... here, so that it can be checked for consistency.
18585 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18587 * xselect.c (x_clipboard_manager_save_frame)
18588 (x_clipboard_manager_save_all): New functions.
18589 (Fx_clipboard_manager_save): Lisp function deleted.
18591 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18592 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18594 * xterm.h: Update prototype.
18596 2011-05-28 William Xu <william.xwl@gmail.com>
18598 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18599 exiting (Bug#8239).
18601 2011-05-28 Jim Meyering <meyering@redhat.com>
18603 Avoid a sign-extension bug in crypto_hash_function.
18604 * fns.c (to_uchar): Define.
18605 (crypto_hash_function): Use it to convert some newly-signed
18606 variables to unsigned, to avoid sign-extension bugs. For example,
18607 without this change, (md5 "truc") would evaluate to
18608 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18609 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18610 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18612 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18614 Integer overflow fixes.
18616 * dbusbind.c: Serial number integer overflow fixes.
18617 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18618 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18619 to hold a serial number that is too large for a fixnum.
18620 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18621 Check for serial numbers out of range. Decode any serial number
18622 that was so large that it became a float. (Bug#8722)
18624 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18625 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18626 Use XFASTINT rather than XUINT when numbers are nonnegative.
18627 (xd_append_arg, Fdbus_method_return_internal):
18628 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18629 arguments, check that Lisp number is nonnegative, rather than
18630 silently wrapping negative numbers around. (Bug#8722)
18631 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18634 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18636 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18638 ccl: Add integer overflow checks.
18639 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18640 (IN_INT_RANGE): New macros.
18641 (ccl_driver): Use them to check for integer overflow when
18642 decoding a CCL program. Many of the new checks are whether XINT (x)
18643 fits in int; it doesn't always, on 64-bit hosts. The new version
18644 doesn't catch all possible integer overflows, but it's an
18645 improvement. (Bug#8719)
18647 * alloc.c (make_event_array): Use XINT, not XUINT.
18648 There's no need for unsigned here.
18650 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18651 This follows up to the 2011-05-06 change that substituted uintptr_t
18652 for EMACS_INT. This case wasn't caught back then.
18654 Rework Fformat to avoid integer overflow issues.
18655 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18656 now (part of C89). Include <verify.h>.
18657 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18658 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18659 (Fformat): Avoid the prepass trying to compute sizes; it was only
18660 approximate and thus did not catch overflow reliably. Instead, walk
18661 through the format just once, formatting and computing sizes as we go,
18662 checking for integer overflow at every step, and allocating a larger
18663 buffer as needed. Keep track separately whether the format is
18664 multibyte. Keep only the most-recently calculated precision, rather
18665 than them all. Record whether each argument has been converted to
18666 string. Use EMACS_INT, not int, for byte and char and arg counts.
18667 Support field widths and precisions larger than INT_MAX. Avoid
18668 sprintf's undefined behavior with conversion specifications such as %#d
18669 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18670 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18671 formatting out-of-range floating point numbers with int
18672 formats. (Bug#8668)
18674 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18676 * data.c: Avoid integer truncation in expressions involving floats.
18677 * data.c: Include <intprops.h>.
18678 (arith_driver): When there's an integer overflow in an expression
18679 involving floating point, convert the integers to floating point
18680 so that the resulting value does not suffer from catastrophic
18681 integer truncation. For example, on a 64-bit host (* 4
18682 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18683 Do not rely on undefined behavior after integer overflow.
18685 merge count_size_as_multibyte, parse_str_to_multibyte
18686 * character.c, character.h (count_size_as_multibyte):
18687 Rename from parse_str_to_multibyte; all uses changed.
18688 Check for integer overflow.
18689 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18690 since it's now a duplicate of the other. This is more of
18691 a character than a buffer op, so better that it's in character.c.
18692 * fns.c, print.c: Adjust to above changes.
18694 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18696 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18698 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18700 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18701 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18702 (x_clipboard_manager_save): Now static.
18703 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18705 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18706 (crypto_hash_function): Now static.
18707 Fix pointer signedness problems. Avoid unnecessary initializations.
18709 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18711 * termhooks.h (Vselection_alist): Make it terminal-local.
18713 * terminal.c (create_terminal): Initialize it.
18715 * xselect.c: Support for clipboard managers.
18716 (Vselection_alist): Move to termhooks.h as terminal-local var.
18717 (LOCAL_SELECTION): New macro.
18718 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18719 (symbol_to_x_atom): Remove gratuitous arg.
18720 (x_handle_selection_request, lisp_data_to_selection_data)
18721 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18722 (x_own_selection, x_get_local_selection, x_convert_selection):
18723 New arg, specifying work frame. Use terminal-local Vselection_alist.
18724 (some_frame_on_display): Delete unused function.
18725 (Fx_own_selection_internal, Fx_get_selection_internal)
18726 (Fx_disown_selection_internal, Fx_selection_owner_p)
18727 (Fx_selection_exists_p): New optional frame arg.
18728 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18729 (x_handle_selection_clear): Don't treat other terminals with the
18730 same keyboard specially. Use the terminal-local Vselection_alist.
18731 (x_clear_frame_selections): Use Frun_hook_with_args.
18733 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18735 * xterm.h: Add support for those atoms.
18737 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18739 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18740 (converted_selections, conversion_fail_tag): New global variables.
18741 (x_selection_request_lisp_error): Free the above.
18742 (x_get_local_selection): Remove unnecessary code.
18743 (x_reply_selection_request): Args changed; handle arbitrary array
18744 of converted selections stored in converted_selections.
18745 Separate the XChangeProperty and SelectionNotify steps.
18746 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18747 (x_convert_selection): New function.
18748 (x_handle_selection_event): Simplify.
18749 (x_get_foreign_selection): Don't ignore incoming requests while
18750 waiting for an answer; this will fail when we implement
18751 SAVE_TARGETS, and seems unnecessary anyway.
18752 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18753 (Vx_sent_selection_functions): Doc fix.
18755 2011-05-26 Leo Liu <sdl.web@gmail.com>
18757 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18759 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18761 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18763 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18764 for fringe update if it has periodic bitmap.
18765 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18766 and fringe_bitmap_periodic_p.
18768 * fringe.c (get_fringe_bitmap_data): New function.
18769 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18770 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18771 row. Mark glyph row for fringe update if periodicity changed.
18773 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18774 for fringe update unless it has periodic bitmap.
18776 2011-05-25 Kenichi Handa <handa@m17n.org>
18778 * xdisp.c (get_next_display_element): Set correct it->face_id for
18779 a static composition.
18781 2011-05-24 Leo Liu <sdl.web@gmail.com>
18784 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18786 * fns.c (crypto_hash_function, Fsha1): New function.
18787 (Fmd5): Use crypto_hash_function.
18788 (syms_of_fns): Add Ssha1.
18790 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18792 * gnutls.c: Remove unused macros.
18793 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18794 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18795 Remove macros that are defined and never used.
18796 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18798 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18800 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18801 (Fx_get_selection_internal): Minor cleanup.
18802 (Fx_own_selection_internal): Rename arguments for consistency with
18805 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18807 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18809 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18811 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18813 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18815 * dispnew.c (scrolling_window): Don't exclude the case that the
18816 last enabled row in the desired matrix touches the bottom boundary.
18818 2011-05-21 Glenn Morris <rgm@gnu.org>
18820 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18821 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18822 and add some more files.
18824 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18826 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18827 report_file_error introduced by the change from 2011-05-07.
18829 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18831 * systime.h (Time): Define only if emacs is defined.
18832 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18833 where the include path doesn't have X11/X.h by default. See
18834 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18836 2011-05-20 Kenichi Handa <handa@m17n.org>
18838 * composite.c (find_automatic_composition): Fix previous change.
18840 2011-05-20 Glenn Morris <rgm@gnu.org>
18842 * lisp.mk: New file, split from Makefile.in.
18843 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18844 (shortlisp): Remove.
18845 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18847 2011-05-19 Glenn Morris <rgm@gnu.org>
18849 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18850 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18851 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18852 (lisp): Set the order to that of loadup.el.
18853 (shortlisp): Make it a copy of $lisp.
18854 (SOME_MACHINE_LISP): Remove.
18855 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18856 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18858 2011-05-18 Kenichi Handa <handa@m17n.org>
18860 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18861 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18862 (find_automatic_composition): Mostly rewrite for efficiency.
18864 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18866 * makefile.w32-in: Update dependencies.
18868 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18870 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18871 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18873 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18875 Fix some integer overflow issues, such as string length overflow.
18877 * insdel.c (count_size_as_multibyte): Check for string overflow.
18879 * character.c (lisp_string_width): Check for string overflow.
18880 Use EMACS_INT, not int, for string indexes and lengths; in
18881 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18882 the resulting string length overflows an EMACS_INT; instead,
18883 report a string overflow if no precision given. When checking for
18884 precision exhaustion, use a check that cannot possibly have
18885 integer overflow. (Bug#8675)
18886 * character.h (lisp_string_width): Adjust to new signature.
18888 * alloc.c (string_overflow): New function.
18889 (Fmake_string): Use it. This doesn't change behavior, but saves
18890 a few bytes and will simplify future changes.
18891 * character.c (string_escape_byte8): Likewise.
18892 * lisp.h (string_overflow): New decl.
18894 Fixups, following up to the user-interface timestamp change.
18895 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18896 for UI timestamps, instead of unsigned long.
18897 * msdos.c (mouse_get_pos): Likewise.
18898 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18899 * w32gui.h (Time): Define by including "systime.h" rather than by
18900 declaring it ourselves. (Bug#8664)
18902 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18903 * image.c (clear_image_cache): Likewise.
18905 * term.c (term_mouse_position): Don't assume time_t wraparound.
18907 Be more systematic about user-interface timestamps.
18908 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18909 and sometimes 'EMACS_UINT', to represent these timestamps.
18910 This change causes it to use 'Time' uniformly, as that's what X uses.
18911 This makes the code easier to follow, and makes it easier to catch
18912 integer overflow bugs such as Bug#8664.
18913 * frame.c (Fmouse_position, Fmouse_pixel_position):
18914 Use Time, not unsigned long, for user-interface timestamps.
18915 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18916 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18917 * keyboard.h (last_event_timestamp): Likewise.
18918 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18919 * menu.h (xmenu_show): Likewise.
18920 * term.c (term_mouse_position): Likewise.
18921 * termhooks.h (struct input_event.timestamp): Likewise.
18922 (struct terminal.mouse_position_hook): Likewise.
18923 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18924 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18925 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18926 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18927 what it was before.
18928 * menu.h, termhooks.h: Include "systime.h", for Time.
18930 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18931 Don't assume that the difference between two unsigned long values
18932 can fit into an integer. At this point, we know button_down_time
18933 <= event->timestamp, so the difference must be nonnegative, so
18934 there's no need to cast the result if double-click-time is
18935 nonnegative, as it should be; check that it's nonnegative, just in
18936 case. This bug is triggered when events are more than 2**31 ms
18937 apart (about 25 days). (Bug#8664)
18939 * xselect.c (last_event_timestamp): Remove duplicate decl.
18940 (x_own_selection): Remove needless cast to unsigned long.
18942 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18943 that always fit in int. Use a sentinel instead of a counter, to
18944 avoid a temp and to allay GCC's concerns about possible int overflow.
18945 * frame.h (struct frame): Use int for menu_bar_items_used
18946 instead of EMACS_INT, since it always fits in int.
18948 * menu.c (grow_menu_items): Check for int overflow.
18950 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18952 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18953 Before, the code was not consistent. These values cannot exceed
18954 2**31 - 1 so there's no need to make them unsigned.
18955 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18956 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18957 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18959 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18961 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18962 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18963 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18964 presumably because the widths might not match.
18966 * window.c (size_window): Avoid needless test at loop start.
18968 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18970 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18972 2011-05-12 Drew Adams <drew.adams@oracle.com>
18974 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18976 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18978 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18979 `width' to `bar_area_x' and `bar_area_width', respectively.
18980 (x_scroll_run): Take account of fringe background extension.
18982 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18983 Rename local vars `left' and `width' to `bar_area_x' and
18984 `bar_area_width', respectively.
18985 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18986 background extension.
18988 2011-05-10 Jim Meyering <meyering@redhat.com>
18990 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18992 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18994 * image.c (Finit_image_library): Return t for built-in image types,
18995 like pbm and xbm. (Bug#8640)
18997 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18999 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19001 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19003 * w32console.c (Fset_screen_color): Doc fix.
19004 (Fget_screen_color): New function.
19005 (syms_of_ntterm): Defsubr it.
19007 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19008 unlink the temporary file if Fcall_process didn't create it in the
19010 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19011 child process will be redirected to a file specified with `:file'.
19012 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19013 cue to call_process_cleanup not to close that handle.
19015 2011-05-07 Ben Key <bkey76@gmail.com>
19017 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19018 one of two shell specific rules, either bootstrap-temacs-CMD or
19019 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19020 to the previous implementation of the bootstrap-temacs rule.
19021 The bootstrap-temacs-CMD rule is similar to the previous
19022 implementation of the bootstrap-temacs rule except that it
19023 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19026 These changes, along with some changes to nt/configure.bat,
19027 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19028 earlier fix to add support for --cflags and --ldflags options
19029 that include quotes so that it works whether make uses cmd or
19032 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19034 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19035 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19037 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19038 a string. Handle both cases.
19039 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19040 (Fdbus_register_method): Use Qinvalid_function.
19042 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19044 * makefile.w32-in: Update dependencies.
19045 (LISP_H): Add inttypes.h and stdin.h.
19046 (PROCESS_H): Add unistd.h.
19048 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19050 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19051 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19053 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19055 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19057 * term.c (vfatal): Remove stray call to va_end.
19058 It's not needed and the C Standard doesn't allow it here anyway.
19060 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19061 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19063 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19066 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19068 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19070 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19072 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19074 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19076 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19077 * charset.c (Fdefine_charset_internal): Don't initialize
19078 charset.code_space[15]. The value was garbage, on hosts with
19079 32-bit int (Bug#8600).
19081 * lread.c (read_integer): Be more consistent with string-to-number.
19082 Use string_to_number to do the actual conversion; this avoids
19083 rounding errors and fixes some other screwups. Without this fix,
19084 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19085 (digit_to_number): Move earlier, for benefit of read_integer.
19086 Return -1 if the digit is out of range for the base, -2 if it is
19087 not a digit in any supported base. (Bug#8602)
19089 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19091 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19092 to match comment at start of function. This also removes a
19093 GCC warning about overflow in a 32+64-bit port.
19095 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19097 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19098 Reported by Stefan Monnier in
19099 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19100 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19101 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19103 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19104 (EMACS_UINTPTR): Likewise, with uintptr_t.
19106 * lisp.h: Prefer 64-bit EMACS_INT if available.
19107 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19108 on 32-bit hosts that have 64-bit int, so that they can access
19110 However, temporarily disable this change unless the temporary
19111 symbol WIDE_EMACS_INT is defined.
19113 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19115 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19116 This removes an assumption that EMACS_INT and long are the same
19117 width as pointers. The assumption is true for Emacs porting targets
19118 now, but we want to make other targets possible.
19119 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19120 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19121 In the rest of the code, change types of integers that hold casted
19122 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19123 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19124 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19125 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19126 No need to cast type when ORing.
19127 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19128 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19129 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19130 assume EMACS_INT is the same width as char *.
19131 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19132 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19133 Remove no-longer-needed casts.
19134 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19135 (xg_tool_bar_help_callback, xg_make_tool_item):
19136 Use EMACS_INTPTR to hold an integer
19137 that will be cast to void *; this can avoid a GCC warning
19138 if EMACS_INT is not the same width as void *.
19139 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19140 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19141 (current_message_1, set_message_1):
19142 Use a local to convert to proper width without a cast.
19143 * xmenu.c (dialog_selection_callback): Likewise.
19145 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19146 Also, don't assume VALBITS / RAND_BITS is less than 5,
19147 and don't rely on undefined behavior when shifting a 1 left into
19149 * lisp.h (get_random): Change signature to match.
19151 * lread.c (hash_string): Use size_t, not int, for hash computation.
19152 Normally we prefer signed values; but hashing is special, because
19153 it's better to use unsigned division on hash table sizes so that
19154 the remainder is nonnegative. Also, size_t is the natural width
19155 for hashing into memory. The previous code used 'int', which doesn't
19156 retain enough info to hash well into very large tables.
19157 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19159 * dbusbind.c: Don't possibly lose pointer info when converting.
19160 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19161 Use XPNTR rather than XHASH, so that the high-order bits of
19162 the pointer aren't lost when converting through void *.
19164 * eval.c (Fautoload): Don't double-shift a pointer.
19166 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19168 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19170 * gnutls.c (DEF_GNUTLS_FN):
19171 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19173 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19175 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19178 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19180 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19181 New version that can reserve upto 2GB of heap space.
19183 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19185 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19187 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19189 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19190 `gnutls_certificate_set_x509_key_file'.
19192 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

19195 Update dependencies.
19197 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19199 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19200 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19201 Remove unused parameter `fildes'.
19202 * process.c (read_process_output, send_process): Don't pass it.
19204 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19206 Fix previous change: the library cache is defined in w32.c.
19207 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19208 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19210 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19212 Implement dynamic loading of GnuTLS on Windows.
19214 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19215 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19216 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19219 * gnutls.c (Qgnutls_dll): Define.

19226 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19227 (emacs_gnutls_write, emacs_gnutls_read)
19228 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19229 (Fgnutls_available_p): New function.
19230 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

19238 (w32_delayed_load): Move to w32.c.
19240 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19242 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19243 (w32_delayed_load): Move from image.c. When loading a library, record
19244 its filename in the :loaded-from property of the library id.
19245 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19246 Initialize and staticpro them.
19247 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19249 * process.c: Include lisp.h before w32.h, not after.
19250 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19251 instead of gnutls_record_check_pending.
19253 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19255 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19257 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19258 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19261 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19263 * xterm.c (x_set_frame_alpha): Do not set property on anything
19264 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19266 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19268 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19270 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19272 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19273 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

19278 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
19279 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
19280 (Qgnutls_bootprop_callbacks_verify): Make static.
19282 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
19284 * callproc.c: Indentation fixup.
19286 * sysdep.c (wait_for_termination_1): Make static.
19287 (wait_for_termination, interruptible_wait_for_termination):
19288 Move after wait_for_termination_1.
19290 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19292 * sysdep.c (interruptible_wait_for_termination): New function
19293 which is like wait_for_termination, but allows keyboard
19296 * callproc.c (Fcall_process): Add (:file "file") as an option for
19298 (Fcall_process_region): Ditto.
19300 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19302 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19303 rather than `XVECTOR (FOO)->size'.
19305 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19306 inttypes.h, as a gnulib replacement is used if it not available in
19309 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19311 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19312 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19313 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19315 * coding.c (coding_alloc_by_realloc): Error out if destination
19316 will grow beyond MOST_POSITIVE_FIXNUM.
19317 (decode_coding_emacs_mule): Abort if there isn't enough place in
19318 charbuf for the composition carryover bytes. Reserve an extra
19319 space for up to 2 characters produced in a loop.
19320 (decode_coding_iso_2022): Abort if there isn't enough place in
19321 charbuf for the composition carryover bytes.
19323 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19325 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19326 aborting when %lld or %lll format is passed.
19327 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19328 %llo or %llx format is passed. (Bug#8545)
19330 * window.c (window_scroll_line_based): Use a marker instead of
19331 simple variables to record original value of point. (Bug#7952)
19333 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19334 produced by %s or %c overflows available buffer space. (Bug#8545)
19336 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19338 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19339 (SIZE_MAX): Move defn after all includes, as they might #define it.
19341 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19343 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19345 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19347 * keyboard.c (Qdelayed_warnings_hook): Define.
19348 (command_loop_1): Run `delayed-warnings-hook'
19349 if Vdelayed_warnings_list is non-nil.
19350 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19351 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19353 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19355 * doprnt.c (doprnt): Don't return value smaller than the buffer
19356 size if the message was truncated. (Bug#8545).
19358 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19360 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19361 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19363 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19365 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19367 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19369 * makefile.w32-in: Update dependencies.
19371 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19373 Improve `doprnt' and its usage. (Bug#8545)
19374 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19375 `format_end'. Remove support for %l as a conversion specifier.
19376 Don't use xrealloc. Improve diagnostics when the %l size modifier
19377 is used. Update the commentary.
19379 * eval.c (verror): Simplify calculation of size_t.
19381 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19384 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19386 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19389 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19391 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19392 This makes this file independent of the recent pseudovector change.
19394 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19396 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19398 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19399 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19400 Remove unused local.
19401 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19403 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19404 GCC 4.6.0 optimizes based on type-based alias analysis.
19405 For example, if b is of type struct buffer * and v of type struct
19406 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19407 != &v->size, and therefore "v->size = 1; b->size = 2; return
19408 v->size;" must therefore return 1. This assumption is incorrect
19409 for Emacs, since it type-puns struct Lisp_Vector * with many other
19410 types. To fix this problem, this patch adds a new type struct
19411 vectorlike_header that documents the constraints on layout of vectors
19412 and pseudovectors, and helps optimizing compilers not get fooled
19413 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19414 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19415 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19417 (XSETPVECTYPE): Rewrite in terms of new macro.
19418 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19419 This is a bit clearer, and further avoids the possibility of
19420 undesirable aliasing.
19421 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19422 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19423 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19424 since Lisp_Subr is a special case (no "next" field).
19425 (ASIZE): Now uses header.size rather than size.
19426 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19427 to avoid the hassle of writing XVECTOR (foo)->header.size.
19428 (struct vectorlike_header): New type.
19429 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19430 object, to help avoid aliasing.
19431 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19432 (SUBRP): Likewise, since Lisp_Subr is a special case.
19433 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19434 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19435 (struct Lisp_Hash_Table): Combine first two members into a single
19436 struct vectorlike_header member. All uses of "size" and "next" members
19437 changed to be "header.size" and "header.next".
19438 * buffer.h (struct buffer): Likewise.
19439 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19440 * frame.h (struct frame): Likewise.
19441 * process.h (struct Lisp_Process): Likewise.
19442 * termhooks.h (struct terminal): Likewise.
19443 * window.c (struct save_window_data, struct saved_window): Likewise.
19444 * window.h (struct window): Likewise.
19445 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19446 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19447 * buffer.c (init_buffer_once): Likewise.
19448 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19450 * process.c (Fformat_network_address): Use local var for size,
19453 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19455 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19456 * data.c (atof): Remove decl; no longer used or needed.
19457 (digit_to_number): Move to lread.c.
19458 (Fstring_to_number): Use new string_to_number function, to be
19459 consistent with how the Lisp reader treats infinities and NaNs.
19460 Do not assume that floating-point numbers represent EMACS_INT
19461 without losing information; this is not true on most 64-bit hosts.
19462 Avoid double-rounding errors, by insisting on integers when
19463 parsing non-base-10 numbers, as the documentation specifies.
19464 * lisp.h (string_to_number): New decl, replacing ...
19465 (isfloat_string): Remove.
19466 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19467 (read1): Do not accept +. and -. as integers; this
19468 appears to have been a coding error. Similarly, do not accept
19469 strings like +-1e0 as floating point numbers. Do not report
19470 overflow for integer overflows unless the base is not 10 which
19471 means we have no simple and reliable way to continue.
19472 Break out the floating-point parsing into a new
19473 function string_to_number, so that Fstring_to_number parses
19474 floating point numbers consistently with the Lisp reader.
19475 (digit_to_number): Move here from data.c. Make it static inline.
19476 (E_CHAR, EXP_INT): Remove, replacing with ...
19477 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19478 (string_to_number): New function, replacing isfloat_string.
19479 This function checks for valid syntax and produces the resulting
19480 Lisp float number too. Rework it so that string-to-number
19481 no longer mishandles examples like "1.0e+". Use strtoumax,
19482 so that overflow for non-base-10 numbers is reported only when
19483 there's no portable and simple way to convert to floating point.
19485 * textprop.c (set_text_properties_1): Rewrite for clarity,
19486 and to avoid GCC warning about integer overflow.
19488 * intervals.h (struct interval): Use EMACS_INT for members
19489 where EMACS_UINT might cause problems. See
19490 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19491 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19492 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19494 (offset_intervals): Tell GCC not to worry about length overflow
19495 when negating a negative length.
19497 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19498 (overrun_check_free): Likewise.
19500 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19501 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19504 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19505 (gnutls_make_error): Rename local to avoid shadowing.
19506 (gnutls_emacs_global_deinit): ifdef out; not used.
19507 (Fgnutls_boot): Use const for pointer to readonly storage.
19508 Comment out unused local. Fix pointer signedness problems.
19510 * lread.c (openp): Don't stuff size_t into an 'int'.
19511 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19512 about possible signed overflow.
19514 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19515 (GDK_KEY_g): Don't define if already defined.
19516 (xg_prepare_tooltip): Avoid pointer signedness problem.
19517 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19519 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19520 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19522 * xfns.c (Fx_window_property): Simplify a bit,
19523 to make a bit faster and to avoid GCC 4.6.0 warning.
19524 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19526 * fns.c (internal_equal): Don't assume size_t fits in int.
19528 * alloc.c (compact_small_strings): Tighten assertion a little.
19530 Replace pEd with more-general pI, and fix some printf arg casts.
19531 * lisp.h (pI): New macro, generalizing old pEd macro to other
19532 conversion specifiers. For example, use "...%"pI"d..." rather
19533 than "...%"pEd"...".
19534 (pEd): Remove. All uses replaced with similar uses of pI.
19535 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19536 * alloc.c (check_pure_size): Don't overflow by converting size to int.

19540 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19541 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19543 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19544 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19545 * print.c (safe_debug_print, print_object): Likewise.
19546 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19548 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19549 avoiding the 0 flag, which is not portable.

19551 * region-cache.c (pp_cache): Likewise.
19552 * xdisp.c (decode_mode_spec): Likewise.

19554 behavior on 64-bit hosts with printf arg.
19555 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19556 (x_stop_queuing_selection_requests): Likewise.
19557 (x_get_window_property): Don't truncate byte count to an 'int'
19560 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19561 here, since it parses constructs like leading '-' and spaces,
19562 which are not wanted; and it overflows with large numbers.
19563 Instead, simply match F[0-9]+, which is what is wanted anyway.
19565 * alloc.c: Remove unportable assumptions about struct layout.
19566 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19567 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19568 (allocate_vectorlike, make_pure_vector): Use the new macros,
19569 plus offsetof, to remove unportable assumptions about struct layout.
19570 These assumptions hold on all porting targets that I know of, but
19571 they are not guaranteed, they're easy to remove, and removing them
19572 makes further changes easier.
19574 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19575 This doesn't fix a bug but makes the code clearer.
19576 (string_overrun_cookie): Now const. Use initializers that
19577 don't formally overflow signed char, to avoid warnings.
19578 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19579 can cause Emacs to crash when string overrun checking is enabled.
19580 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19581 multiple of sizeof (EMACS_INT); it need not be, if
19582 alignof(EMACS_INT) < sizeof (EMACS_INT).
19583 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19585 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19617 Improve doprnt and its use in verror. (Bug#8545)
19618 * doprnt.c (doprnt): Document the set of format control sequences
19619 supported by the function. Use SAFE_ALLOCA instead of always
19622 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19623 is one byte too soon. Don't use xrealloc; instead xfree and

19635 docstring. Start callback support.
19636 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19637 unless a fatal error occurred. Call gnutls_alert_send_appropriate

19741 codepoint of an invalid character, to avoid displaying a bogus
19744 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19745 `error', not SYMBOL_NAME itself.

19750 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19751 to `error' in error message about FINAL_CHAR argument. Make sure
19752 FINAL_CHAR is a character, and use %c when it is passed as
19753 argument to `error'.
19755 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19757 * s/ms-w32.h (localtime): Redirect to sys_localtime.
19759 * w32.c: Include <time.h>.

19819 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
19820 by pacifying GCC about it. Maybe it's time to retire it?
19821 * xfaces.c (USG, __TIMEVAL__): Likewise.
19823 * dispextern.h (struct redisplay_interface): Rename param
19824 to avoid shadowing.
19825 * termhooks.h (struct terminal): Likewise.

19942 * nsfont.m: Fixed bugs in ns_get_family and
19943 ns_descriptor_to_entity that were caused by using free to
19944 deallocate memory blocks that were allocated by xmalloc (via
19945 xstrdup). This caused Emacs to crash when compiled with
19946 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19947 --enable-checking=xmallocoverrun). xfree is now used to
19948 deallocate these memory blocks.

19962 (emacs_read, emacs_write): Remove check for negative size, as the
19963 Emacs source code has been audited now.
19964 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
19965 (emacs_read, emacs_write): Use it.
19966 * process.c (send_process): Adjust to the new signatures of
19967 emacs_write and emacs_gnutls_write. Do not attempt to store
19968 a byte offset into an 'int'; it might overflow.

19995 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>
19997 Improve C-level modularity by making more things 'static'.

20416 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20418 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20419 when at ZV. (Bug#8487)
20421 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20423 * charset.c (Fclear_charset_maps): Use xfree instead of free.
20425 * keyboard.c (parse_tool_bar_item): Likewise.
20426 * sound.c (sound_cleanup, alsa_close): Likewise.
20427 * termcap.c (tgetent): Likewise.
20428 * xfns.c (x_default_font_parameter): Likewise.
20429 * xsettings.c (read_and_apply_settings): Likewise.
20431 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20432 (overrun_check_free): Protoize.
20434 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20436 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20437 since callers should never pass a negative size.
20438 Change the signature to match that of plain 'read' and 'write'; see
20439 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20440 * lisp.h: Update prototypes of emacs_write and emacs_read.
20442 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20444 * xdisp.c (redisplay_window): Don't try to determine the character
20445 position of the scroll margin if the window start point w->startp
20446 is outside the buffer's accessible region. (Bug#8468)
20448 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20450 Fix write-region and its subroutines for buffers > 2GB.
20451 * fileio.c (a_write, e_write): Modify declaration of arguments and
20452 local variables to support buffers larger than 2GB.
20453 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20455 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20456 argument, local variables, and return value.
20458 * lisp.h: Update prototypes of emacs_write and emacs_read.
20460 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20462 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20464 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20466 Fix more problems found by GCC 4.6.0's static checks.
20468 * xdisp.c (vmessage): Use a better test for character truncation.
20470 * charset.c (load_charset_map): <, not <=, for optimization,
20471 and to avoid potential problems with integer overflow.
20472 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20473 * casetab.c (set_identity, shuffle): Likewise.
20474 * editfns.c (Fformat): Likewise.
20475 * syntax.c (skip_chars): Likewise.
20477 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20478 This also lets GCC 4.6.0 generate slightly better loop code.
20480 * callint.c (Fcall_interactively): <, not <=, for optimization.
20481 (Fcall_interactively): Count the number of arguments produced,
20482 not the number of arguments given. This is simpler and lets GCC
20483 4.6.0 generate slightly better code.
20485 * ftfont.c: Distingish more carefully between FcChar8 and char.
20486 The previous code passed unsigned char * to a functions like
20487 strlen and xstrcasecmp that expect char *, which does not
20488 conform to the C standard.
20489 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20490 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20491 char * when the C standard requires it.
20493 * keyboard.c (read_char): Remove unused var.
20495 * eval.c: Port to Windows vsnprintf (Bug#8435).
20496 Include <limits.h>.
20497 (SIZE_MAX): Define if the headers do not.
20498 (verror): Do not give up if vsnprintf returns a negative count.
20499 Instead, grow the buffer. This ports to Windows vsnprintf, which
20500 does not conform to C99. Problem reported by Eli Zaretskii.
20501 Also, simplify the allocation scheme, by avoiding the need for
20502 calling realloc, and removing the ALLOCATED variable.
20504 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20506 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20507 But keep the doprint source code for now, as we might revamp it
20508 and use it again (Bug#8435).
20509 * lisp.h (doprnt): Remove.
20510 * Makefile.in (base_obj): Remove doprnt.o.
20511 * deps.mk (doprnt.o): Remove.
20513 error: Print 32- and 64-bit integers portably (Bug#8435).
20514 Without this change, on typical 64-bit hosts error ("...%d...", N)
20515 was used to print both 32- and 64-bit integers N, which relied on
20516 undefined behavior.
20517 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20518 * lisp.h (error, verror): Mark as printf-like functions.
20519 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20520 Report overflow in size calculations when allocating printf buffer.
20521 Do not truncate output string at its first null byte.
20522 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20523 Truncate the output at a character boundary, since vsnprintf does not
20525 * charset.c (check_iso_charset_parameter): Convert internal
20526 character to string before calling 'error', since %c now has the
20528 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20529 overflow when computing char to be passed to 'error'. Do not
20530 pass Lisp_Object to 'error'; pass the integer instead.
20531 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20532 formatted with plain %d.
20534 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20536 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20538 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20540 * xterm.c (x_catch_errors): Remove duplicate declaration.
20542 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20544 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20546 2011-04-10 Jim Meyering <meyering@redhat.com>
20548 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20549 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20550 return ssize_t not "int", and use size_t as the buffer length.
20551 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20552 * gnutls.h: Update declarations.
20553 * process.c (read_process_output): Use ssize_t, to match.
20554 (send_process): Likewise.
20556 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20558 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20560 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20562 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20563 Use unsigned char, to match FcChar8 type definition.
20565 * xterm.c (handle_one_xevent):
20566 * xmenu.c (create_and_show_popup_menu):
20567 * xselect.c (x_decline_selection_request)
20568 (x_reply_selection_request): Avoid type-punned deref of X events.
20570 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20572 Fix some uses of `int' instead of EMACS_INT.
20573 * search.c (string_match_1, fast_string_match)
20574 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20575 (scan_buffer, find_next_newline_no_quit)
20576 (find_before_next_newline, search_command, Freplace_match)
20577 (Fmatch_data): Make some `int' variables be EMACS_INT.
20579 * xdisp.c (display_count_lines): 3rd argument and return value now
20580 EMACS_INT. All callers changed.
20581 (pint2hrstr): Last argument is now EMACS_INT.
20583 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20584 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20585 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20586 (decode_coding_utf_16, decode_coding_emacs_mule)
20587 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20588 (decode_coding_ccl, decode_coding_charset)
20589 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20590 (decode_coding_iso_2022, decode_coding_emacs_mule)
20591 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20592 <char_offset, last_offset>: Declare EMACS_INT.
20593 (encode_coding_utf_8, encode_coding_utf_16)
20594 (encode_coding_emacs_mule, encode_invocation_designation)
20595 (encode_designation_at_bol, encode_coding_iso_2022)
20596 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20597 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20599 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20600 (encode_invocation_designation): Last argument P_NCHARS is now
20602 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20603 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20605 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20608 * ccl.c (Fccl_execute_on_string): Declare some variables
20611 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20613 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20615 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20617 * process.c (Fformat_network_address): Doc fix.
20619 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20621 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20623 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20625 * keyboard.c (read_char): Call Lisp function help-form-show,
20626 instead of using internal_with_output_to_temp_buffer.
20627 (Qhelp_form_show): New var.
20628 (syms_of_keyboard): Use DEFSYM macro.
20630 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20632 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20634 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20636 * process.c (Flist_processes): Remove to Lisp.
20637 (list_processes_1): Delete.
20639 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20641 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20643 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20645 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20647 Fix more problems found by GCC 4.6.0's static checks.
20649 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20651 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20653 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20655 * xdisp.c (vmessage): Mark as a printf-like function.
20657 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20659 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20661 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20662 printf-like functions.
20663 (tiff_load): Add casts to remove these marks before passing them
20664 to system-supplied API.
20666 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20668 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20669 This avoids several warnings with gcc -Wstrict-overflow.
20670 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20671 directly, rather than having caller test rule sign. This avoids
20672 some unnecessary tests.
20673 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20674 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20675 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20677 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20678 (xfont_open): Avoid unnecessary tests.
20680 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20682 * composite.h, composite.c (composition_gstring_put_cache):
20683 Use EMACS_INT, not int, for length.

20686 breaking out part of COMPOSITION_DECODE_RULE.
20687 (COMPOSITION_DECODE_RULE): Use it.

20689 by using the new macro.
20691 * textprop.c (set_text_properties_1): Change while to do-while,
20692 since the condition is always true at first.
20694 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20695 (interval_deletion_adjustment): Return unsigned value.
20698 * process.c (list_processes_1, create_pty, read_process_output):

20708 (update_syntax_table): Use unsigned instead of int.
20710 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20711 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20712 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20714 * print.c (print_error_message): Avoid int overflow.
20716 * font.c (font_list_entities): Redo for clarity,
20717 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20719 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20720 (font_score): Avoid potential overflow in diff calculation.
20722 * fns.c (substring_both): Remove var that is set but not used.
20723 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20725 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20727 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20728 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20729 can always succeed if overflow has undefined behavior.
20731 * search.c (boyer_moore, wordify): Remove vars set but not used.
20732 (wordify): Omit three unnecessary tests.
20734 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20735 All callers changed. This avoids the need for an unused var.
20737 * casefiddle.c (casify_region): Remove var that is set but not used.
20739 * dired.c (file_name_completion): Remove var that is set but not used.
20741 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20743 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20744 (Finsert_file_contents): Remove unnecessary code checking fd.
20746 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20747 Check for integer overflow on size calculations.
20749 * buffer.c (Fprevious_overlay_change): Remove var that is set
20752 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20753 Remove vars that are set but not used.
20754 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20755 (timer_check_2): Mark vars as initialized.
20757 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20759 * image.c (lookup_image): Remove var that is set but not used.
20760 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20762 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20763 that are set but not used.
20765 * xfns.c (make_invisible_cursor): Don't return garbage
20766 if XCreateBitmapFromData fails (Bug#8410).
20768 * xselect.c (x_get_local_selection, x_handle_property_notify):
20769 Remove vars that are set but not used.
20771 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

20781 (map_tty_color) [!defined MSDOS]: Likewise.
20783 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20785 * coding.c: Remove vars that are set but not used.
20786 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20787 All callers changed.
20788 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20789 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20790 (decode_coding_charset): Remove vars that are set but not used.
20792 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20793 that is set but not used.
20795 * print.c (print_object): Remove var that is set but not used.
20797 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20798 The gnulib version avoids calling malloc in the usual case,
20799 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20800 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20801 * filelock.c (current_lock_owner): Likewise.
20802 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20803 * sysdep.c: Include allocator.h, careadlinkat.h.
20804 (emacs_no_realloc_allocator): New static constant.
20805 (emacs_readlink): New function.
20806 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20807 ../lib/careadlinkat.h.
20809 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20811 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20812 first non-nil return value).
20814 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20816 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20817 if not defined (Bug#8403).
20819 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20821 * xdisp.c (display_count_lines): Remove parameter `start',
20822 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20823 (get_char_face_and_encoding): Remove parameter `multibyte_p',

20826 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20827 and thereabouts. All callers changed.
20828 (get_per_char_metric): Remove parameter `f', unused since
20829 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20833 do not dereference NULL upon failed strdup
20834 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20835 (ns_get_family): Likewise.
20837 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20839 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20841 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20843 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

20859 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20861 (syms_of_lread): Declare `lexical-binding'.
20863 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20865 * keyboard.c (eval_dyn): New fun.
20866 (menu_item_eval_property): Use it.
20868 * image.c (parse_image_spec): Use Ffunctionp.
20870 * fns.c (concat, mapcar1): Accept byte-code-functions.
20872 * eval.c (Fsetq): Handle lexical vars.
20873 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20874 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20875 (FletX, Flet): Obey lexical binding.
20876 (Fcommandp): Handle closures.
20877 (Feval): New `lexical' arg.
20878 (eval_sub): New function extracted from Feval. Use it almost
20879 everywhere where Feval was used. Look up vars in lexical env.
20881 (Ffunctionp): Move from subr.el.
20882 (Ffuncall): Handle closures.
20883 (apply_lambda): Remove `eval_flags'.
20884 (funcall_lambda): Handle closures and new byte-code-functions.
20885 (Fspecial_variable_p): New function.
20886 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20887 but without exporting it to Lisp.
20889 * doc.c (Fdocumentation, store_function_docstring):
20890 * data.c (Finteractive_form): Handle closures.
20892 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20895 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20897 (exec_byte_code): New function extracted from Fbyte_code to handle new
20898 calling convention for byte-code-functions. Add new byte-codes.
20900 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20902 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20904 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20906 * xdisp.c (redisplay_internal): Fix prototype.
20908 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20910 * xdisp.c (SCROLL_LIMIT): New macro.
20911 (try_scrolling): Use it when setting scroll_limit.
20912 Limit scrolling to 100 screen lines.
20913 (redisplay_window): Even when falling back on "recentering",
20914 position point in the window according to scroll-conservatively,
20915 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20917 (try_scrolling): When point is above the window, allow searching
20918 as far as scroll_max, or one screenful, to compute vertical
20919 distance from PT to the scroll margin position. This prevents
20920 try_scrolling from unnecessarily failing when
20921 scroll-conservatively is set to a value slightly larger than the
20922 window height. Clean up the case of PT below the margin at bottom
20923 of window: scroll_max can no longer be INT_MAX. When aggressive
20924 scrolling is in use, don't let point enter the opposite scroll
20925 margin as result of the scroll.
20926 (syms_of_xdisp) <scroll-conservatively>: Document the
20927 threshold of 100 lines for never-recentering scrolling.
20929 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20931 * dispextern.h (move_it_by_lines):
20932 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20933 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20934 (message_log_check_duplicate): Remove parameters `prev_bol' and
20935 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20936 (redisplay_internal): Remove parameter `preserve_echo_area',
20937 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20939 * indent.c (Fvertical_motion):
20940 * window.c (window_scroll_pixel_based, Frecenter):
20941 Don't pass `need_y_p' to `move_it_by_lines'.
20943 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20945 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20946 steal a few bits to be more compact.
20947 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20948 Remove unneeded casts.
20950 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20952 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20954 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20955 binding" message (bug#7967).
20957 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20959 Fix more problems found by GCC 4.6.0's static checks.
20961 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20962 Remove unused local var.
20964 * editfns.c (Fmessage_box): Remove unused local var.
20966 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20967 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20968 Omit unused local vars.
20969 * window.c (shrink_windows): Omit unused local var.
20970 * menu.c (digest_single_submenu): Omit unused local var.
20971 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20972 Omit unused local var.
20974 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20975 Don't assume string length fits in int.
20976 (keyremap_step, read_key_sequence): Use size_t for sizes.
20977 (read_key_sequence): Don't check last_real_key_start redundantly.
20979 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20980 instead of alloca (Bug#8344).
20982 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20983 (Fbacktrace_frame): Don't assume nframes fits in int.
20985 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20987 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20990 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20992 * cm.c (calccost): Turn while-do into do-while, for clarity.
20994 * keyboard.c (syms_of_keyboard): Use the same style as later
20995 in this function when indexing through an array. This also
20996 works around GCC bug 48267.
20998 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21000 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21002 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21003 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21005 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21006 This avoids undefined behavior on integer overflow, and is a bit
21007 more convenient anyway since it is compared to a size_t variable.
21009 Variadic C functions now count arguments with size_t, not int.
21010 This avoids an unnecessary limitation on 64-bit machines, which
21011 caused (substring ...) to crash on large vectors (Bug#8344).
21012 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21013 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21014 All variadic functions and their callers changed accordingly.
21015 (struct gcpro.nvars): Now size_t, not int. All uses changed.

21017 * editfns.c (general_insert_function): Likewise.
21018 * eval.c (struct backtrace.nargs, interactive_p)
21019 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21020 (funcall_lambda, mark_backtrace): Likewise.
21021 * fns.c (concat): Likewise.
21022 * frame.c (x_set_frame_parameters): Likewise.
21023 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21024 0 if not found, not -1. All callers changed.
21026 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21027 (stack_copy_size): Now size_t, not int.
21028 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21030 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21032 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21033 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21034 All callers changed.
21036 * lisp.h (multibyte_char_to_unibyte):
21037 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21038 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21039 * character.h (CHAR_TO_BYTE8):
21040 * cmds.c (internal_self_insert):
21041 * editfns.c (general_insert_function):
21042 * keymap.c (push_key_description):
21043 * search.c (Freplace_match):
21044 * xdisp.c (message_dolog, set_message_1): All callers changed.
21046 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21048 * keyboard.c (safe_run_hook_funcall): New function.
21049 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21050 don't set the hook to nil, but remove the offending function instead.
21051 (Qcommand_hook_internal): Remove, unused.
21052 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21053 Vcommand_hook_internal.
21055 * eval.c (enum run_hooks_condition): Remove.
21056 (funcall_nil, funcall_not): New functions.
21057 (run_hook_with_args): Call each function through a `funcall' argument.
21058 Remove `cond' argument, now redundant.
21059 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21060 (Frun_hook_with_args_until_failure): Adjust accordingly.
21061 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21063 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21065 * dispextern.h (string_buffer_position): Remove declaration.
21067 * print.c (strout): Remove parameter `multibyte', unused since
21068 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21070 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21071 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21072 All callers changed.
21074 * w32.c (_wsa_errlist): Use braces for struct initializers.
21076 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21077 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21078 All callers changed.
21079 (string_buffer_position): Likewise. Also, make static (it's never
21080 used outside xdisp.c).
21081 (cursor_row_p): Remove parameter `w', unused since
21082 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21084 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21085 All callers changed.
21087 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21089 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
21091 2011-03-27 Anders Lindgren <andlind@gmail.com>
21093 * nsterm.m (ns_menu_bar_is_hidden): New variable.
21094 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
21095 (ns_update_auto_hide_menu_bar): New functions.
21096 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

21100 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21102 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21104 * nsmenu.m (runDialogAt): Remove argument to timer_check.
21106 2011-03-27 Glenn Morris <rgm@gnu.org>
21108 * syssignal.h: Replace RETSIGTYPE with void.
21109 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
21110 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
21111 Replace SIGTYPE with void everywhere.
21112 * s/usg5-4-common.h (SIGTYPE): Remove definition.
21113 * s/template.h (SIGTYPE): Remove commented out definition.
21115 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21117 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21118 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21120 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21122 * w32.c (read_unc_volume): Use parameter `henum', instead of
21123 global variable `wget_enum_handle'.
21125 * keymap.c (describe_vector): Remove parameters `indices' and
21126 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
21127 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
21129 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
21131 * keyboard.c (timer_check): Remove parameter `do_it_now',
21132 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
21133 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
21134 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
21136 * keyboard.c (read_char):
21137 * w32menu.c (w32_menu_display_help):
21138 * xmenu.c (show_help_event, menu_help_callback):
21139 Adjust calls to `show_help_echo'.
21141 * gtkutil.c (xg_maybe_add_timer):
21142 * keyboard.c (readable_events):
21143 * process.c (wait_reading_process_output):
21144 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21146 * insdel.c (adjust_markers_gap_motion):
21147 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
21148 (gap_left, gap_right): Don't call it.
21150 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

21194 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
21196 * w32term.c (x_set_glyph_string_clipping):
21197 Don't pass uninitialized region to CombineRgn.
21199 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
21201 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
21202 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
21203 (Fx_close_connection): Remove unused variable `i'.
21205 * w32font.c (w32font_draw): Return number of glyphs.
21206 (w32font_open_internal): Remove unused variable `i'.

21219 (uniscribe_font_driver): Add missing initializers.
21221 2011-03-23 Julien Danjou <julien@danjou.info>
21223 * term.c (Fsuspend_tty, Fresume_tty):
21224 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21225 * window.c (temp_output_buffer_show):
21226 * insdel.c (signal_before_change):
21227 * frame.c (Fhandle_switch_frame):
21228 * fileio.c (Fdo_auto_save):
21229 * emacs.c (Fkill_emacs):
21230 * editfns.c (save_excursion_restore):
21231 * cmds.c (internal_self_insert):
21232 * callint.c (Fcall_interactively):
21233 * buffer.c (Fkill_all_local_variables):
21234 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21236 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21237 unconditionally since it does the check itself.
21239 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21241 Fix more problems found by GCC 4.5.2's static checks.
21243 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21244 the first time through the loop, since we know p0 < p1 then.
21245 This also avoids a gcc -Wstrict-overflow warning.
21247 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21248 leading to a memory leak, possible in functions like
21249 load_charset_map_from_file that can allocate an unbounded number
21250 of objects (Bug#8318).
21252 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21253 that could (at least in theory) be that large.
21255 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21256 This is less likely to overflow, and avoids undefined behavior if
21257 overflow does occur. All callers changed. Use strtoul to scan
21258 for the unsigned long integer.
21259 (pint2hrstr): Simplify and tune code slightly.
21260 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21262 * scroll.c (do_scrolling): Work around GCC bug 48228.
21263 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
21265 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
21266 This also avoids a warning with gcc -Wstrict-overflow.
21267 (validate_x_resource_name): Simplify count usage.
21268 This also avoids a warning with gcc -Wstrict-overflow.
21270 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21273 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21275 * process.c (Fmake_network_process): Use socklen_t, not int,
21276 where POSIX says socklen_t is required in portable programs.
21277 This fixes a porting bug on hosts like 64-bit HP-UX, where
21278 socklen_t is wider than int (Bug#8277).
21279 (Fmake_network_process, server_accept_connection):
21280 (wait_reading_process_output, read_process_output):
21283 * process.c: Rename or move locals to avoid shadowing.
21284 (list_processes_1, Fmake_network_process):
21285 (read_process_output_error_handler, exec_sentinel_error_handler):
21286 Rename or move locals.
21287 (Fmake_network_process): Define label "retry_connect" only if needed.
21288 (Fnetwork_interface_info): Fix pointer signedness.
21289 (process_send_signal): Add cast to avoid pointer signedness problem.
21290 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21291 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21293 Make tparam.h and terminfo.c consistent.
21294 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21295 Include tparam.h instead, since it declares them.
21296 * cm.h (PC): Remove extern decl; tparam.h now does this.

21355 clobbering (Bug#8298).
21356 * sysdep.c (sys_subshell): Likewise.
21357 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21359 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21360 This should get cleaned up, so that child_setup has the
21361 same signature on all platforms.
21363 * callproc.c (call_process_cleanup): Now static.
21364 (relocate_fd): Rename locals to avoid shadowing.
21366 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

21525 (Fmemory_limit): Cast sbrk's returned value to char *.
21527 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21535 to use the following functions instead of these macros.
21536 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21537 EMACS_INT, since callers assume the returned value fits in int.
21538 (upcase1): Likewise, for UPCASE_TABLE.
21539 (uppercasep, lowercasep, upcase): New static inline functions.
21540 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21550 (regex_compile, re_match_2_internal): Mark locals as initialized.
21551 (RETALLOC_IF): Define only if needed.
21552 (WORDCHAR_P): Likewise. This one is never needed, but is used
21553 only in a comment talking about a compiler bug, so put inside
21554 the #if 0 of that comment.
21555 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21556 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21583 New macros, so that the caller can use some names other than
21584 gcpro1, gcpro2, etc.
21585 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21587 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21588 argument, for consistency with GCPRO2_VAR, etc: it is now the
21589 prefix of the variable, not the variable itself. All uses
21591 * dired.c (directory_files_internal, file_name_completion):
21592 Rename locals to avoid shadowing.
21594 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21595 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21596 dired.c's scmp function, had undefined behavior.
21597 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21598 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21599 * buffer.h: ... to here, because these macros use current_buffer,
21600 and the new implementation with inline functions needs to have
21601 current_buffer in scope now, rather than later when the macros
21603 (downcase, upcase1): New static inline functions.
21604 (DOWNCASE, UPCASE1): Reimplement using these functions.
21605 This avoids undefined behavior in expressions like
21606 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21607 from race conditions in accessing the global variables
21608 case_temp1 and case_temp2.
21609 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21610 * lisp.h (case_temp1, case_temp2): Remove their decls.
21611 * character.h (ASCII_CHAR_P): Move from here ...
21612 * lisp.h: ... to here, so that the inline functions mentioned
21613 above can use them.

21620 (file_name_as_directory): Use const pointers when appropriate.

21624 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21626 (Fset_file_times, Finsert_file_contents, auto_save_error):

21633 * marker.c (bytepos_to_charpos): Remove; unused.
21635 * lisp.h (verify_bytepos, count_markers): New decls,
21636 so that gcc does not warn that these functions aren't declared.

21639 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

21646 * buffer.c (fix_overlays_before): Mark locals as initialized.
21647 (fix_start_end_in_overlays): Likewise. This function should be
21648 simplified by using pointers-to-pointers, but that's a different

21651 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21652 (report_overlay_modification): Rename locals to avoid shadowing.

21657 to suppress a gcc -Wclobbered warning that does not seem to be right.
21658 (MAXPATHLEN): Define only if needed.
21660 * process.c (serial_open, serial_configure): Move decls from here ...
21661 * systty.h: ... to here, so that they can be checked.
21663 * fns.c (get_random, seed_random): Move extern decls from here ...
