[gnu-emacs] / src / ChangeLog
1 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2
3 * callproc.c (Fcall_process): Make sure program name in PATH and
4 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
5 is passed to exec/spawnve, which fails unless the file-name
6 encoding is UTF-8.
7
8 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
9 even if w32-quote-process-args is nil.
10
11 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
12
13 Fix timestamp bug when write-region appends nothing (Bug#13149).
14 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
15 the file's time stamp doesn't change if Emacs happens to write nothing
16 to the file, and on a buggy file system this could cause Emacs to
17 incorrectly infer that the file system doesn't have the bug.
18 Avoid this problem by inhibiting the inference in this case.
19
20 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
21
22 * window.h (struct window): Convert base_line_number, base_line_pos
23 and column_number_displayed members from Lisp_Object to ptrdiff_t.
24 Convert region_showing member from Lisp_Object to bitfield.
25 Remove sequence_number member. Adjust comments.
26 * window.c (sequence_number): Remove.
27 (make_window): Initialize column_number_displayed.
28 * print.c (print_object): Follow the printed representation of
29 frames and print window pointer to distinguish between windows.
30 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
31 * xdisp.c (wset_base_line_number, wset_base_line_pos)
32 (wset_column_number_displayed, wset_region_showing): Remove.
33 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
34 (try_scrolling, try_cursor_movement, redisplay_window)
35 (try_window_reusing_current_matrix, try_window_id, display_line)
36 (display_mode_lines, decode_mode_spec): Adjust users.
37 * .gdbinit (pwinx): Do not print sequence_number.
38
39 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
40
41 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
42 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
43 * dired.c: Include <fcntl.h>.
44 (open_directory): New function, which uses open and fdopendir
45 rather than opendir. DOS_NT platforms still use opendir, though.
46 (directory_files_internal, file_name_completion): Use it.
47 (file_attributes): New function, with most of the old Ffile_attributes.
48 (directory_files_internal, Ffile_attributes): Use it.
49 (file_attributes, file_name_completion_stat): First arg is now fd,
50 not dir name. All uses changed. Use fstatat rather than lstat +
51 stat.
52 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
53 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
54 (emacs_readlinkat): New function, with much of the old
55 Ffile_symlink_p, but with an fd argument for speed.
56 It uses readlinkat rather than careadlinkatcwd, so that it
57 need not assume the working directory.
58 (Ffile_symlink_p): Use it.
59 * filelock.c (current_lock_owner): Use emacs_readlinkat
60 rather than emacs_readlink.
61 * lisp.h (emacs_readlinkat): New decl.
62 (READLINK_BUFSIZE, emacs_readlink): Remove.
63 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
64 (emacs_norealloc_allocator, emacs_readlink): Remove.
65 This stuff is moved to fileio.c.
66 * w32.c (fstatat, readlinkat): New functions.
67 (careadlinkat): Don't check that fd == AT_FDCWD.
68 (careadlinkatcwd): Remove; no longer needed.
69
70 2013-01-31 Glenn Morris <rgm@gnu.org>
71
72 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
73 (Fwrite_region): Update for new choose_write_coding_system args.
74 Move the last piece of choose_write_coding_system here. (Bug#13522)
75 (syms_of_fileio): Add choose-write-coding-system.
76
77 2013-01-30 Eli Zaretskii <eliz@gnu.org>
78
79 * w32.c (sys_open): Zero out the flags for the new file descriptor.
80 (sys_close): Zero out the flags for the file descriptor before
81 closing it. (Bug#13546)
82
83 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
84 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
85 CharNextExA and CharPrevExA to iterate over file names encoded in
86 DBCS. (Bug#13553)
87
88 * w32.c (w32_get_long_filename, init_environment, readlink):
89 Support file names encoded in DBCS codepages.
90 (readlink): Use the current file-name-coding-system, not the ANSI
91 codepage, to decode and handle targets of symlinks.
92
93 2013-01-28 Eli Zaretskii <eliz@gnu.org>
94
95 * w32.c (opendir): Now accepts a 'const char *'.
96
97 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
98
99 Remove obsolete redisplay code. See the discussion at
100 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
101 * dispnew.c (preemption_period, preemption_next_check): Remove.
102 (Vredisplay_preemption_period): Likewise.
103 (update_frame, update_single_window, update_window, update_frame_1):
104 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
105 used, following the 2012-06-22 change.
106
107 2013-01-25 Eli Zaretskii <eliz@gnu.org>
108
109 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
110
111 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
112
113 * font.c (num_fonts): Remove the leftover from old
114 debugging code. Adjust comment style here and there.
115 * insdel.c (insert_1): Remove.
116 * lisp.h (insert_1): Remove prototype.
117 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
118
119 2013-01-25 Eli Zaretskii <eliz@gnu.org>
120
121 * w32.c (max_filename_mbslen): New function.
122 (normalize_filename, readdir): Use it to detect locales where ANSI
123 encoding of file names uses a double-byte character set (DBCS).
124 If a DBCS encoding is used, advance by characters using
125 CharNextExA, instead of incrementing a 'char *' pointer. Use
126 _mbslwr instead of _strlwr. (Bug#13515)
127
128 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
129 request of memory reservation to 1.7GB. (Bug#13065)
130
131 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
132
133 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
134 at check_extra_latin label. (Bug#13505)
135
136 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
137
138 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
139 Avoid redundant calls to strlen.
140
141 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
142
143 Drop async_visible and async_iconified fields of struct frame.
144 This is possible because async input is gone; for details, see
145 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
146 * frame.h (struct frame): Remove async_visible and async_iconified
147 members, convert garbaged to unsigned bitfield. Adjust comments.
148 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
149 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
150 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
151 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
152 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
153 * w32term.c: Ditto.
154 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
155 properly. Likewise for obscured.
156 * xterm.c: Ditto.
157 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
158 properly.
159 * nsterm.m: Ditto.
160 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
161
162 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
163
164 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
165 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
166
167 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
168
169 * xdisp.c (message2, message2_nolog): Remove functions.
170 (message3, message3_nolog): Extract nbytes and multibyteness directly
171 from the string. Change all callers.
172 (message3_nolog): Don't set message_enable_multibyte since set_message
173 will reset it anyway.
174 (message1, message1_nolog): Use message3.
175 (vmessage): Use a stack allocated buffer rather than f->message_buf.
176 (with_echo_area_buffer): Remove last two arguments. Update all callers.
177 (set_message): Drop all but the second arg, which has to be a string.
178 (set_message_1): Simplify now that we know that a1 is NULL and the
179 second arg is a string.
180 * frame.h (struct frame): Remove `message_buf' field.
181 Use glyphs_initialized_p instead.
182 (FRAME_MESSAGE_BUF): Remove macro.
183 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
184 * lisp.h (message2, message2_nolog): Remove declarations.
185 (message3, message3_nolog): Update declarations.
186 * keyboard.c (read_char_minibuf_menu_text)
187 (read_char_minibuf_menu_width): Remove vars.
188 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
189 to correctly handle multibyte strings.
190 * frame.c (delete_frame): Don't free message_buf any more.
191 * editfns.c (message_text, message_length): Remove vars.
192 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
193 * fileio.c (auto_save_error): Use message3 instead of message2.
194 * dispnew.c (adjust_frame_message_buffer): Remove function.
195
196 2013-01-23 Eli Zaretskii <eliz@gnu.org>
197
198 * w32term.c (w32fullscreen_hook): Account correctly for the screen
199 real estate used for the tool bar and the menu bar.
200
201 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
202
203 * insdel.c (prepare_to_modify_buffer): Force redisplay if
204 hidden buffer is prepared to modification (Bug#13164).
205
206 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
207
208 * window.h (struct window): Change window_end_valid member from
209 Lisp_Object to a bitfield. Adjust comments.
210 (wset_window_end_valid): Remove.
211 * window.c (adjust_window_count): Clear window_end_valid.
212 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
213 (Fwindow_line_height, set_window_buffer, Frecenter)
214 (Fsplit_window_internal, Fdelete_other_windows_internal)
215 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
216 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
217 * xdisp.c (check_window_end, reconsider_clip_changes)
218 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
219 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
220 (find_first_unchanged_at_end_row, try_window_id): Likewise.
221
222 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
223
224 * xdisp.c (mark_window_display_accurate): Simplify the loop
225 assuming that the only one of vchild, hchild or buffer window
226 slots is non-nil. Call mark_window_display_accurate_1 for
227 the leaf windows only.
228 (mark_window_display_accurate_1): Always assume leaf window.
229 Adjust comment.
230
231 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
232
233 * emacs.c (Qkill_emacs_hook): Now static.
234
235 * fileio.c (Finsert_file_contents): Simplify.
236 Remove unnecessary assignments and tests.
237
238 2013-01-21 Eli Zaretskii <eliz@gnu.org>
239
240 * w32.c (acl_set_file): Don't test for errors unless
241 set_file_security returns FALSE. Avoids spurious errors when
242 saving files.
243
244 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
245
246 * fileio.c (Finsert_file_contents): Revert code introduced at
247 2013-01-18 in favor of the simpler and generally better fix.
248 Save stack space by removing 'buffer' and reusing 'read_buf'
249 where appropriate.
250
251 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
252
253 * lisp.h (eabs): Define unconditionally (Bug#13419).
254 The old "#if !defined (eabs)" was an unnecessary revenant of back
255 when this macro was called "abs". Document 'eabs' better.
256
257 2013-01-19 Glenn Morris <rgm@gnu.org>
258
259 * fns.c (Frandom): Doc fix.
260
261 2013-01-19 Eli Zaretskii <eliz@gnu.org>
262
263 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
264 segfault when there are lots of overlays.
265
266 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
267 when there are lots of overlays. See
268 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
269 for the details and a way to reproduce.
270
271 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
272
273 * fileio.c: Use O_APPEND to append.
274 This corresponds better to the natural interpretation of "append",
275 and avoids the need to open the output file twice, or to invoke
276 lseek when APPEND is neither nil nor a number.
277 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
278 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
279 file possibly twice, and lseeking to its end; this avoids the
280 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
281 at the same time: the combination is never needed and apparently
282 it doesn't work with DOS_NT.
283
284 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
285 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
286
287 Allow floating-point file offsets.
288 Problem reported by Vitalie Spinu in
289 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
290 * fileio.c (emacs_lseek): Remove.
291 (file_offset): New function.
292 (Finsert_file_contents, Fwrite_region): Use it.
293
294 2013-01-19 Chong Yidong <cyd@gnu.org>
295
296 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
297 aborting on Fsignal (Bug#13289).
298
299 2013-01-19 Eli Zaretskii <eliz@gnu.org>
300
301 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
302 set_file_security as failure due to insufficient privileges.
303 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
304 (fstat): Return owner and group like 'stat' and 'lstat' do.
305
306 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
307
308 Work around bug in CIFS and vboxsf file systems (Bug#13149).
309 The bug was observed on Ubuntu operating inside a virtual machine,
310 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
311 The workaround introduces a race condition on non-buggy hosts,
312 but it's an unlikely race and anyway there's a nearly identical
313 nearby race that can't be fixed.
314 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
315 New static vars.
316 (Fwrite_region): Test for file system time stamp bug.
317 (init_fileio): New function.
318 * lisp.h (init_fileio): Declare it.
319 * emacs.c (main): Call it.
320
321 * fileio.c (Finsert_file_contents): Simplify new diagnostic
322 and make it more consistent with other stat-failure diagnostics.
323
324 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
325
326 Fix crash when inserting data from non-regular files. See
327 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
328 for the error description produced by valgrind.
329 * fileio.c (read_non_regular): Rename to read_contents.
330 Free Lisp_Save_Value object used to pass parameters.
331 (read_non_regular_quit): Rename to read_contents_quit.
332 (Finsert_file_contents): Redesign internal file reading loop to adjust
333 gap and end positions after each read and so help make_gap to work
334 properly. Do not signal an I/O error too early and so do not leave
335 not yet decoded characters in a buffer, which was the reason of
336 redisplay crash. Use list2 to build return value. Adjust comments.
337
338 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
339
340 Close a race when statting and reading files (Bug#13149).
341 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
342 This avoids a race if the file is renamed between stat and open.
343 This race is not the problem originally noted in Bug#13149;
344 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
345
346 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
347
348 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
349 objects, related functions and macros.
350 (make_save_value): Adjust prototype.
351 (make_save_pointer): New prototype.
352 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
353 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
354 * alloc.c (format_save_value): Rename to make_save_value.
355 (make_save_pointer): New function.
356 (record_xmalloc): Use make_save_pointer.
357 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
358 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
359 Change users of make_save_value to make_save_pointer.
360 Likewise for format_save_value and make_save_value.
361
362 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
363
364 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
365 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
366 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
367 debugging stubs.
368
369 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
370
371 * alloc.c (free_save_value): Now static.
372
373 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
374
375 * keymap.c (map_keymap_internal): Use format_save_value.
376 (map_keymap_char_table_item): Adjust accordingly.
377 * fileio.c (non_regular_fd, non_regular_inserted)
378 (non_regular_nbytes): Remove.
379 (Finsert_file_contents): Convert trytry to ptrdiff_t. Use
380 format_save_value to pass parameters to read_non_regular.
381 (read_non_regular): Use XSAVE_ macros to extract parameters.
382 Adjust comment.
383 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
384 format_save_value.
385 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
386
387 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
388
389 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
390 extraction from any Lisp_Save_Value slot. Add type checking.
391 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
392 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
393 * xselect.c: All users changed.
394
395 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
396
397 Some convenient bits to deal with Lisp_Save_Values.
398 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
399 (allocate_misc): Remove prototype.
400 (format_save_value): New prototype.
401 * alloc.c (allocate_misc): Revert back to static.
402 (format_save_value): New function to build Lisp_Save_Value
403 object with the specified internal structure.
404 (make_save_value): Reimplement using format_save_value.
405 * editfns.c (save_excursion_save): Use format_save_value.
406 (save_excursion_restore): Use XSAVE_OBJECT.
407
408 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
409
410 Avoid needless casts with XSAVE_POINTER.
411 * alloc.c (mark_object) [GC_MARK_STACK]:
412 * dired.c (directory_files_internal_unwind):
413 * fileio.c (do_auto_save_unwind):
414 * gtkutil.c (pop_down_dialog):
415 * keymap.c (map_keymap_char_table_item):
416 * lread.c (load_unwind):
417 * nsmenu.m (pop_down_menu):
418 * print.c (print_object) [GC_MARK_STACK]:
419 * xfns.c (clean_up_file_dialog):
420 * xmenu.c (cleanup_widget_value_tree):
421 Omit casts between XSAVE_POINTER and a pointer type.

443 * editfns.c (save_excursion_save): Pack everything within
444 Lisp_Save_Value and so avoid xmalloc.
445 (save_excursion_restore): Adjust to match new layout. Use free_misc
446 because we do not allocate extra memory any more. Add eassert.
447 * print.c (print_object): New code to print Lisp_Save_Value. Do not
448 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
449 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
450 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
451 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.

461
462 Fix SIGDANGER handlers, for AIX (Bug#13408).
463 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
464 Move handlers here from emacs.c; they were out of place.
465
466 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
467
468 * xterm.c (syms_of_xterm): Adjust documentation for

515
516 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
517
518 Avoid unnecessary byte position calculation for the gap movement.
519 Since all users of move_gap do CHAR_TO_BYTE for other purposes
520 anyway, all of them should use move_gap_both instead.
521 * lisp.h (move_gap): Remove prototype.
522 * insdel.c (move_gap): Remove.
523 (move_gap_both): Add eassert.

530 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
531 New functions.
532 * term.c (init_tty): Use them instead of rolling our own code.
533 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
534 switches from 'signal' to 'pthread_sigmask', which is safer in
535 multithreaded applications.
536 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
537 which has already arranged for that.
538 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
539 This is the main part of the bug fix.

549 the type of per-buffer values where appropriate.
550 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
551 predicate, which is how it's really used now. Adjust comment.
552 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
553 * buffer.c (buffer_slot_type_mismatch): Remove.
554 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
555 predicate. Adjust comment.
556 (syms_of_buffer): Use Qsymbolp for major-mode. Use Qintegerp for

558 left-margin-width, right-margin-width, left-fringe-width,
559 right-fringe-width, scroll-bar-width and buffer-display-count.
560 Use Qstringp for default-directory, buffer-file-name,
561 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
562 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
563 line-spacing.
564 * data.c (store_symval_forwarding): Adjust to call the predicate.
565
566 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
567

574 * buffer.h (GAP_BYTES_DFL, GAP_BYTES_MIN): New macros for the special
575 gap size values.
576 * editfns.c (Fbuffer_size): Rename from Fbufsize to fit the common
577 naming convention.
578 (syms_of_editfns): Adjust defsubr. Drop commented-out obsolete code.
579 * insdel.c (make_gap_larger): Use GAP_BYTES_DFL. Adjust comment.
580 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
581 (make_gap_1): New function to adjust the gap of any buffer.
582 * coding.c (coding_alloc_by_making_gap): Use it.
583 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
584 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
585
586 2013-01-08 Juri Linkov <juri@jurta.org>
587
588 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
589 of (supports :underline (:style wave)). (Bug#13000)
590
591 2013-01-08 Aaron S. Hawley <aaron.s.hawley@gmail.com>
592

599
600 2013-01-06 Chong Yidong <cyd@gnu.org>
601
602 * keyboard.c (echo_add_char): New function, factored out from
603 echo_char. Don't add a space if the previous echo string was
604 empty (Bug#13255).
605 (echo_char): Use it.
606 (read_key_sequence): When echoing mock input, ensure that the
607 trailing dash is properly added.
608
609 2013-01-05 Eli Zaretskii <eliz@gnu.org>
610
611 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
612 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
613 digits for buffer positions, before misalignment starts.
614 Display "0" for integer "object" field.
615 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
616 Display the newline glyph more unambiguously.
617
618 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
619

626 * w32term.c (x_draw_glyph_string):
627 * xterm.c (x_draw_glyph_string): Don't use previous underline
628 thickness and position if previous underline type is underwave.
629
630 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
631
632 * fileio.c (Ffile_acl): Undocument return format.
633
634 2013-01-02 Glenn Morris <rgm@gnu.org>
635
636 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
637
638 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
639
640 Simplify via eabs.
641 * dired.c (file_name_completion):
642 * doc.c (get_doc_string):
643 * floatfns.c (round2):
644 * font.c (font_score, font_delete_unmatched):
645 * fringe.c (compute_fringe_widths):
646 * lread.c (read_list):
647 * minibuf.c (Ftry_completion):
648 * term.c (tty_ins_del_lines):
649 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
650 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
651
652 2012-12-31 Eli Zaretskii <eliz@gnu.org>
653
654 * w32.c (unsetenv): Set up the string passed to _putenv
655 correctly.
656 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
657 for the bug this caused.
658
659 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
660
661 * coding.c (Qmac): Now static.
662
663 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
664
665 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
666 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
667 handlebox_widget. Set toolbar_in_hbox to false/true, set
668 toolbar_is_packed to true.
669 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
670 (update_frame_tool_bar): Check toolbar_is_packed for packing.
671 Show all on TOOLBAR_TOP_WIDGET.
672 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
673 by TOOLBAR_TOP_WIDGET.
674 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
675 Check toolbar_is_packed.
676 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
677 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
678 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
679 false.
680 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
681 (xg_update_menubar): Update title only if
682 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
683 (xg_update_submenu): Skip tearoff only if
684 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
685 (xg_initialize): Initialize xg_detached_menus only if
686 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
687
688 * xterm.h (struct x_output): Surround handlebox_widget with
689 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
690 toolbar_in_hbox is bool.
691
692 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
693
694 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
695 (LIBS_GNUSTEP): Define.
696 (LIBES): Add $(LIBS_GNUSTEP).
697 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
698
699 2012-12-30 Eli Zaretskii <eliz@gnu.org>
700
701 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
702 continuation glyph on a TTY with an indication of an empty line.
703 (Bug#13277)
704
705 2012-12-29 Eli Zaretskii <eliz@gnu.org>
706
707 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
708 file's SELinux context or ACLs successfully set, nil otherwise.
709 (Bug#13298)
710 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
711
712 * w32proc.c (reader_thread): Avoid passing NULL handles to
713 SetEvent and WaitForSingleObject.
714
715 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
716
717 Port EXTERNALLY_VISIBLE to Clang 3.2.
718 * conf_post.h (__has_attribute): New macro.
719 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
720
721 2012-12-27 Glenn Morris <rgm@gnu.org>
722
723 * cygw32.c (Fcygwin_convert_file_name_to_windows)
724 (Fcygwin_convert_file_name_from_windows): Doc fixes.
725
726 2012-12-27 Eli Zaretskii <eliz@gnu.org>
727
728 * fileio.c (file_name_as_directory, directory_file_name):
729 Accept an additional argument MULTIBYTE to indicate whether the input C
730 came from a multibyte or a unibyte Lisp string; all callers
731 adjusted. Don't assume the input string is always multibyte.
732 (Bug#13262)
733 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
734 don't ENCODE_FILE them, and return a unibyte string if the input
735 was unibyte.
736 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
737 don't assume the input strings will always be multibyte. If the
738 input strings are multibyte, decode strings obtained from C
739 library functions.
740
741 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
742
743 * lisp.h (toplevel): Add two notices to the comment about
744 defining a new Lisp data type.
745 * print.c (print_object): If Lisp_Save_Value object's pointer
746 is the address of a memory area containing Lisp_Objects, try
747 to print them.
748 * alloc.c (valid_lisp_object_p): Adjust comment.
749
750 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
751
752 * keyboard.c (record_asynch_buffer_change): Initialize an event
753 only if it's really needed.
754 * frame.h (enum output_method): Remove output_mac member since
755 it's a leftover from the deleted code.
756 * frame.c (Fframep): Adjust user here ...
757 * terminal.c (Fterminal_live_p): ... and here.
758 * coding.c (Qmac): Now here because it's only used to denote
759 end-of-line encoding type.
760 (syms_of_coding): DEFSYM it.
761 * frame.h (Qmac): Remove duplicated declaration.
762
763 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
764
765 * window.c (select_window_1): Now static, since it's used only here.
766
767 2012-12-25 Eli Zaretskii <eliz@gnu.org>
768
769 * window.c (window_body_cols): Subtract display margins from the
770 window body width on TTYs as well. See
771 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
772 for the original report.
773
774 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
775
776 * xdisp.c (redisplay_window): Remove inner local variable
777 because the outer shadowed one has the same meaning.
778 * xterm.h (struct x_output): Remove toolbar_detached member since it's
779 set but never used.
780 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
781 (xg_create_tool_bar): Adjust users.
782
783 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
784
785 * buffer.h (BUF_COMPACT): New macro to follow the common style.
786 * buffer.c (Fget_buffer_create): Use it to set compact field of
787 struct buffer_text to avoid accessing an uninitialized value
788 when compact_buffer is called for the first time.
789 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
790 (Fset_buffer_modified_p): Use buffer_window_count to check
791 whether the buffer is displayed in some window.
792 * xdisp.c (message_dolog): Likewise.
793
794 2012-12-23 Eli Zaretskii <eliz@gnu.org>
795
796 * w32.c (acl_set_file): If setting the file security descriptor
797 fails, and the new DACL is identical to the existing one, silently
798 return success. This fixes problems for users backing up their
799 own files without having the necessary privileges for setting
800 security descriptors.
801
802 * w32proc.c (reader_thread): Do not index fd_info[] with negative
803 values.
804 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
805 after WaitForSingleObject returns normally. This expedites reader
806 thread shutdown when delete_child triggers it.
807 (reap_subprocess): More accurate commentary for why we call
808 delete_child only when cp->fd is negative.
809
810 * w32.c (sys_close): Do not call delete_child on a subprocess
811 whose handle is not yet closed. Instead, set its file descriptor
812 to a negative value, so that reap_subprocess will call
813 delete_child on that subprocess when its SIGCHLD arrives.
814 This avoids closing handles used for communications between sys_select
815 and reader_thread, which doesn't give sys_select a chance to
816 notice that the process exited and invoke the SIGCHLD handler for
817 it.
818
819 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
820
821 * nsfns.m (Fns_do_applescript): Run event loop until script has
822 been executed (Bug#12969).
823 (ns_run_ascript): Chech as_script for nil, set to nil after
824 executing script.
825
826 2012-12-22 Martin Rudalics <rudalics@gmx.at>
827
828 * window.c (Fselect_window): Reword doc-string (Bug#13248).
829
830 2012-12-22 Eli Zaretskii <eliz@gnu.org>
831
832 * w32term.c (w32fullscreen_hook): New function.
833 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
834
835 2012-12-21 Eli Zaretskii <eliz@gnu.org>
836
837 * fileio.c (Finsert_file_contents): Doc fix.
838
839 * w32proc.c (new_child, delete_child, find_child_pid): For a
840 subprocess, consider its slot being in use as long as its process
841 handle (procinfo.hProcess) is not NULL. This avoids reusing the
842 slot when a new process is started immediately after killing
843 another one, without waiting enough time for the first process to
844 be reaped and resources allocated for it be orderly freed.
845 (Bug#13086)
846 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
847
848 2012-12-21 Chong Yidong <cyd@gnu.org>
849
850 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
851
852 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
853
854 2012-12-21 Eli Zaretskii <eliz@gnu.org>
855
856 * w32.c (get_name_and_id): Always pass NULL as the first argument
857 of lookup_account_sid. Avoids crashes with UNC file names that
858 refer to DFS domains, not to specific machine names. (Bug#12621)
859 Remove now unused argument FNAME; all callers changed.
860 (get_file_owner_and_group): Remove now unused argument FNAME; all
861 callers changed.

904 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
905 (code_convert_region): Likewise.
906

908
909 * w32.c (acl_get_file, acl_set_file): Run the file name through

913 enabled.
914
915 2012-12-17 Juanma Barranquero <lekktu@gmail.com>

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

963
964 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
965
966 * sysdep.c (emacs_abort): Bump backtrace size to 40.

971
972 * fileio.c (Ffile_acl, Fset_file_acl): New functions.

1003
1004 * lisp.h (internal_delete_file): Adjust prototype.
1005
1006 * callproc.c (Fcall_process): Don't overwrite infile with result
1007 of DECODE_FILE.
1008 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1009 asynchronous subprocess, record the name of the input file name,
1010 if any.
1011 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1012 delete the file, record it as pending deletion when the subprocess
1013 exits.

1037 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1038 try to get accurate owner and group information from NT file
1039 security APIs. This is to make most callers of 'stat' and
1040 'lstat', which don't need that information, much faster.
1041
1042 * dired.c (Ffile_attributes) [WINDOWSNT]:
1043 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1044 owner and group information from 'lstat'.

1046 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1047
1048 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1049 as that confuses set-auto-coding, so insist on the head-read
1050 returning the full 1024 bytes. Let lseek compute the tail offset;
1051 less work for us. Do not ignore I/O errors when reading the tail.
1052
1053 * xdisp.c: Minor style fixes.
1054 (init_iterator): Hoist assignment out of if-expression.
1055 (markpos_of_region): Callers now test for sign, not for -1.

1077
1078 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1079
1080 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1081 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1082 Remove unnecessary S_ISLNK test, as (contra the comments) this
1083 function can't copy symlinks. Improve quality of error message
1084 when attempting to copy files that are neither regular files nor
1085 directories.
1086
1087 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>

1094
1095 2012-12-12 Daniel Colascione <dancol@dancol.org>
1096
1097 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1098 the dumped Emacs is not a sparse file, greatly improving Cygwin
1099 "make bootstrap" performance.

1112 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1113 iterator's start_of_box_run_p flag before prepending the stretch.
1114 (append_glyph, produce_image_glyph, append_composite_glyph)
1115 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1116 left_box_line_p and right_box_line_p flags of the glyph for R2L
1117 glyph rows. (Bug#13011)

1293
1294 2012-12-10 Eli Zaretskii <eliz@gnu.org>
1295
1296 * indent.c (Fvertical_motion): If a display string will be
1297 displayed on the left or the right margin, don't consider it as a
1298 factor in cursor positioning. (Bug#13108)
1299
1300 2012-12-10 Martin Rudalics <rudalics@gmx.at>
1301
1302 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
1303
1304 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>
1305
1306 * fileio.c (Fsubstitute_in_file_name): Use ptrdiff_t, not int,
1307 for string length.
1308
1309 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1310
1311 * w32.c (unsetenv): Return 0 if the input string is too long.
1312
1313 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1314
1315 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1316 * alloc.c (xputenv): New function.
1317 * dbusbind.c (Fdbus_init_bus):
1318 * emacs.c (main):
1319 * xterm.c (x_term_init):
1320 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
1321 * editfns.c (initial_tz): Move static var decl up.
1322 (tzvalbuf_in_environ): New static var.
1323 (init_editfns): Initialize these two static vars.
1324 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1325 Save old TZ value on stack, if it's small.
1326 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1327 instead, use xputenv+unsetenv to set and restore TZ.
1328 (environbuf): Remove static var. All uses removed.
1329 (Fset_time_zone_rule): Do not save TZ and environ;
1330 no longer needed here.
1331 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1332 Move to inside set_time_zone_rule; they don't need file scope any more.
1333 (set_time_zone_rule): Maintain the TZ=value string separately.
1334 (syms_of_editfns): Don't initialize initial_tz;
1335 init_editfns now does it.
1336 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1337 * lisp.h (xputenv): New decl.
1338
1339 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1340
1341 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1342
1343 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1344
1345 * w32.c (unsetenv, sys_putenv): New functions.
1346
1347 2012-12-08 Chong Yidong <cyd@gnu.org>
1348
1349 * editfns.c (Finsert_char): Make the error message more
1350 informative (Bug#12992).
1351
1352 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1353
1354 Simplify get_lim_data.
1355 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1356 Remove USG and vlimit methods; no longer used these days.
1357 Add #error catchall just in case.
1358
1359 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1360 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1361 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1362 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1363 (deleted_pid_list, Fdelete_process, create_process)
1364 (record_child_status_change, handle_child_signal, deliver_child_signal)
1365 (init_process_emacs, syms_of_process):
1366 Assume SIGCHLD is defined.
1367 (parse_signal): Remove. All uses removed.
1368 (abbr_to_signal): New static function.
1369 (Fsignal_process): Use it to convert signal names to ints.
1370 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1371 kill (getpgrp (), ...).
1372 (emacs_sigaction_init): Assume SIGCHLD is defined.
1373 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1374 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1375 * syssignal.h (EMACS_KILLPG): Remove.
1376 All uses replaced by 'kill' with a negative pid.
1377 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1378 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1379
1380 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1381
1382 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1383 This will cause a production Emacs to dump core instead of
1384 infinite-looping.
1385
1386 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1387
1388 * frame.c (make_frame): Do not set window's buffer to t.
1389 * window.c (Fsplit_window_internal): Likewise. Previously it was
1390 used to indicate that the window is being set up. Now we use
1391 set_window_buffer for all new windows, so the condition in ...
1392 (Fset_window_buffer): ... is always true and can be removed.
1393
1394 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1395
1396 Convenient macro to check whether the buffer is hidden.
1397 * buffer.h (BUFFER_HIDDEN_P): New macro.
1398 * frame.c (make_frame): Use it. Adjust comment.
1399 * buffer.c (candidate_buffer): New function.
1400 (Fother_buffer, other_buffer_safely): Use it.
1401
1402 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1403
1404 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1405 if the child process is still running. Instead, exit the wait
1406 loop and return zero. (Bug#13086)
1407
1408 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1409
1410 * frame.h (x_char_width, x_char_height): Remove prototypes.
1411 * w32term.h (x_char_width, x_char_height): Likewise.
1412 * xfns.c (x_char_width, x_char_height): Remove.
1413 * w32fns.c (x_char_width, x_char_height): Likewise.
1414 * nsfns.c (x_char_width, x_char_height): Likewise.
1415 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
1416 all window frames.
1417 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
1418 * keyboard.c (command_loop_1): Remove prototype.
1419 (command_loop_2, top_level_1): Add static to match prototype.
1420
1421 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1422
1423 Fix a recently-introduced delete-process race condition.
1424 * callproc.c, process.h (record_kill_process):
1425 New function, containing part of the old call_process_kill.
1426 (call_process_kill): Use it.
1427 This does not change call_process_kill's behavior.
1428 * process.c (Fdelete_process): Use record_kill_process to fix a
1429 race condition that could cause Emacs to lose track of a child.
1430
1431 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1432
1433 Avoid code duplication between prev_frame and next_frame.
1434 * frame.c (candidate_frame): New function. Add comment.
1435 (prev_frame, next_frame): Use it. Adjust comment.
1436
1437 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1438
1439 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1440 fails, signal an error instead of continuing with an empty
1441 string. (Bug#13079)
1442 Encode expanded temp file pattern before passing it to mkstemp or
1443 mktemp.
1444
1445 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1446 Encode the file name before passing it to dostounix_filename, in
1447 case it will downcase it (under w32-downcase-file-names).
1448 (Bug#12933)
1449
1450 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1451
1452 Minor call-process cleanups.
1453 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1454 at the same time as other platforms, to simplify analysis.
1455 No need for fd0_volatile since we have synch_process_fd.
1456 Avoid needless emacs_close; arg is always negative.
1457
1458 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1459
1460 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1461 processes.
1462
1463 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1464
1465 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1466 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1467 and mouse_face_hidden members to a bitfields.
1468 * frame.h (struct frame): Remove set-but-not-used space_width member.
1469 (FRAME_SPACE_WIDTH): Remove.
1470 * nsterm.m, w32term.c, xterm.c: Adjust users.
1471 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1472 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1473 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1474 members to a bitfields.
1475
1476 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1477
1478 Don't let call-process be a zombie factory (Bug#12980).
1479 Fixing this bug required some cleanup of the signal-handling code.
1480 As a side effect, this change also fixes a longstanding rare race
1481 condition whereby Emacs could mistakenly kill unrelated processes,
1482 and it fixes a bug where a second C-g does not kill a recalcitrant
1483 synchronous process in GNU/Linux and similar platforms.
1484 The patch should also fix the last vestiges of Bug#9488,
1485 a bug which has mostly been fixed on the trunk by other changes.
1486 * callproc.c, process.h (synch_process_alive, synch_process_death)
1487 (synch_process_termsig, sync_process_retcode):
1488 Remove. All uses removed, to simplify analysis and so that
1489 less consing is done inside critical sections.
1490 * callproc.c (call_process_exited): Remove. All uses replaced
1491 with !synch_process_pid.
1492 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1493 These take the role of what used to be in unwind-protect arg.
1494 All uses changed.
1495 (block_child_signal, unblock_child_signal):
1496 New functions, to avoid races that could kill innocent-victim processes.
1497 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1498 (call_process_kill): Record killed processes as deleted, so that
1499 zombies do not clutter up the system. Do this inside a critical
1500 section, to avoid a race that would allow the clutter.
1501 (call_process_cleanup): Fix code so that the second C-g works again
1502 on common platforms such as GNU/Linux.
1503 (Fcall_process): Create the child process in a critical section,
1504 to fix a race condition. If creating an asynchronous process,
1505 record it as deleted so that zombies do not clutter up the system.
1506 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1507 light of these changes. Omit unnecessary call to emacs_close
1508 before failure, as the unwind-protect code does that.
1509 * callproc.c (call_process_cleanup):
1510 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1511 * process.c (record_deleted_pid): New function, containing
1512 code refactored out of Fdelete_process.
1513 (Fdelete_process): Use it.
1514 (process_status_retrieved): Remove. All callers changed to use
1515 child_status_change.
1516 (record_child_status_change): Remove, folding its contents into ...
1517 (handle_child_signal): ... this signal handler. Now, this
1518 function is purely a handler for SIGCHLD, and is not called after
1519 a synchronous waitpid returns; the synchronous code is moved to
1520 wait_for_termination. There is no need to worry about reaping
1521 more than one child now.
1522 * sysdep.c (get_child_status, child_status_changed): New functions.
1523 (wait_for_termination): Now takes int * status and bool
1524 interruptible arguments, too. Do not record child status change;
1525 that's now the caller's responsibility. All callers changed.
1526 Reimplement in terms of get_child_status.
1527 (wait_for_termination_1, interruptible_wait_for_termination):
1528 Remove. All callers changed to use wait_for_termination.
1529 * syswait.h: Include <stdbool.h>, for bool.
1530 (record_child_status_change, interruptible_wait_for_termination):
1531 Remove decls.
1532 (record_deleted_pid, child_status_changed): New decls.
1533 (wait_for_termination): Adjust to API changes noted above.
1534
1535 * bytecode.c, lisp.h (Qbytecode): Remove.
1536 No longer needed after 2012-11-20 interactive-p changes.
1537
1538 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1539
1540 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1541 the scroll margin, move point outside the margin. (Bug#13055)
1542
1543 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1544
1545 * gtkutil.c (my_log_handler): New function.
1546 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1547
1548 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1549
1550 * lisp.h (modify_region): Rename to...
1551 (modify_region_1): ...new prototype.
1552 * textprop.c (modify_region): Now static. Adjust users.
1553 * insdel.c (modify_region): Rename to...
1554 (modify_region_1): ...new function to work with current buffer.
1555 Adjust comment and users. Use true and false for booleans.
1556
1557 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1558
1559 * alloc.c (free_save_value): New function.
1560 (safe_alloca_unwind): Use it.
1561 * lisp.h (free_save_value): New prototype.
1562 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1563 Add comment.
1564 (save_excursion_restore): Adjust to match saved data structure.
1565 Use free_save_value to offload some work from GC. Drop obsolete
1566 #if 0 code.
1567
1568 2012-12-03 Chong Yidong <cyd@gnu.org>
1569
1570 * fileio.c (Vauto_save_list_file_name): Doc fix.
1571
1572 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1573
1574 * w32fns.c: Remove prototype of atof.
1575 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1576 builds.
1577 (file_dialog_callback): Make it UINT_PTR.
1578
1579 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1580 with 64-bit builds.
1581
1582 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1583 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1584 defined.
1585
1586 2012-12-03 Glenn Morris <rgm@gnu.org>

1589
1590 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1591
1592 Fix xpalloc confusion after memory is exhausted.
1593 * alloc.c (xpalloc): Comment fix.
1594 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1595 and signals an error, do not clear charset_table_size, as
1596 charset_table is still valid.
1597 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1598
1599 Use execve to avoid need to munge environ (Bug#13054).
1600 * callproc.c (Fcall_process):
1601 * process.c (create_process):
1602 Don't save and restore environ; no longer needed.
1603 * callproc.c (child_setup):
1604 Use execve, not execvp, to preserve environ.
1605
1606 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1607
1608 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).

1611
1612 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1613 display for sliced images (Bug#10500).
1614
1615 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1616
1617 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1618
1619 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1620 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1621
1622 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1623
1624 * xdisp.c (window_outdated): Remove eassert since it hits
1625 some suspicious corner cases (see Bug#13007 and Bug#13012).
1626 (mode_line_update_needed): New function.
1627 (redisplay_internal, redisplay_window): Use it.
1628 (ensure_selected_frame): New function.
1629 (redisplay_internal, unwind_redisplay): Use it.

1634
1635 * callproc.c (Fcall_process): Don't misreport vfork failure.
1636
1637 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1638
1639 * callproc.c (Fcall_process): Fix vfork portability problems.
1640 Do not assume that fd[0], count, filefd, and save_environ survive
1641 vfork. Fix bug whereby wrong errno value could be reported for
1642 pipe failure. Some minor cleanups, too, as follows. Move buf and
1643 bufsize to the context where they're needed. Change new_argv to
1644 be of type char **, as this is more convenient and avoids casts.
1645 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1646 Now local constants, not macros.
1647
1648 2012-11-18 Kenichi Handa <handa@gnu.org>
1649
1650 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1651 for the variable "f".
1652
1653 2012-11-13 Kenichi Handa <handa@gnu.org>
1654
1655 * font.c (font_unparse_xlfd): Exclude special characters from the
1656 generating XLFD name.
1657
1658 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1659
1660 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

1679 (Bug#11964)
1680
1681 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1682 highlighting on the frame was cleared. Prevents assertion
1683 violations when repeatedly clicking on the "Top" link of the
1684 "bread-crumbs" in Info buffers.
1685
1686 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

1693 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1694 were always defined.
1695
1696 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1697
1698 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1699 between bpos_covered and bpos_max. This fixes cursor display when
1700 several display strings follow each other.
1701
1702 * .gdbinit (pgx): If the glyph's object is a string, display the
1703 pointer to string data, rather than the value of the string object
1704 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1705
1706 * indent.c (Fvertical_motion): If the starting position is covered
1707 by a display string, return to one position before that, to avoid
1708 overshooting it inside move_it_to. (Bug#12930)
1709
1710 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1711
1712 * frame.h (struct frame): Remove display_preempted member
1713 since all users are dead long ago.
1714 * nsterm.h (struct x_output): Use the only dummy member.
1715 * w32menu.c (pending_menu_activation): Remove since not
1716 really used.
1717 (set_frame_menubar): Adjust user.
1718 * w32term.h (struct x_output): Drop outdated #if 0 code.
1719 (struct w32_output): Use bitfields for explicit_parent,
1720 asked_for_visible and menubar_active members.
1721 Drop unused pending_menu_activation member.
1722 * xterm.h (struct x_output): Drop outdated #if 0 code.
1723 Use bitfields for explicit_parent, asked_for_visible,
1724 has_been_visible and net_wm_state_hidden_seen members.
1725
1726 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1727
1728 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1729 of a literal "/". (Bug#12955)
1730 (gl-stamp): Invoke fc.exe directly, not through cmd.
1731
1732 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1733
1734 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1735 * dired.c: Assume HAVE_DIRENT_H.
1736 (NAMLEN): Remove, replacing with ...
1737 (dirent_namelen): New function. All uses changed. Use the GNU macro
1738 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1739 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1740 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1741 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1742 $(NT_INC)/dirent.h.
1743 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1744 * ndir.h: Rename to ../nt/inc/dirent.h.
1745 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1746 Do not include <dirent.h>; no longer needed.
1747 * w32.c: Include <dirent.h> rather than "ndir.h".
1748
1749 2012-11-23 Chong Yidong <cyd@gnu.org>
1750
1751 * xftfont.c (xftfont_open): Remove duplicate assignment.

1754
1755 * alloc.c (Fgarbage_collect): Unblock input after clearing
1756 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1757 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1758 * msdos.c (IT_frame_up_to_date): Use it here...
1759 * w32term.c (w32_frame_up_to_date): ...here...
1760 * xterm.c (XTframe_up_to_date): ...and here...
1761 * nsterm.m (ns_frame_up_to_date): ...but not here.
1762 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1763 Adjust users.
1764 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

1770 (update_menu_bar, update_tool_bar): Use it to
1771 simplify large 'if' statements.
1772 (redisplay_internal): Generalize commonly used
1773 'tail' and 'frame' local variables.
1774
1775 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1776
1777 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1778 with Windows system header.
1779
1780 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1781
1782 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1783 * alloc.c: Assume unistd.h exists.
1784 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1785 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1786 (getwd) [USG]: Remove; no longer needed.
1787 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1788 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1789 * w32.h (getcwd): Remove decl.
1790
1791 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1792
1793 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1794 Make it set selected_window as well.
1795 (update_tool_bar): Use it.
1796
1797 2012-11-21 Ken Brown <kbrown@cornell.edu>
1798
1799 * emacs.c (main): Set the G_SLICE environment variable for all
1800 Cygwin builds, not just GTK builds. See
1801 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1802
1803 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1804
1805 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1806 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1807 Define for the MSVC compiler.
1808
1809 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1810
1811 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1812 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1813 dostounix_filename. Prevents crashes down the road, because
1814 dostounix_filename assumes it gets a unibyte string.
1815 Reported by Michel de Ruiter <michel@sentient.nl>, see

1818 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1819
1820 Conflate Qnil and Qunbound for `symbol-function'.
1821 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
1822 * lread.c (init_obarray): Set `function' fields to Qnil.
1823 * eval.c (Fcommandp): Ignore Qunbound.
1824 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1825 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1826 Test NILP rather than Qunbound.
1827 (Ffmakunbound): Set to Qnil.
1828 (Fsymbol_function): Never signal an error.
1829 (Finteractive_form): Ignore Qunbound.
1830
1831 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1832

1836
1837 * xdisp.c (buffer_shared): Adjust comment.
1838 (buffer_shared_and_changed): New function.
1839 (prepare_menu_bars, redisplay_internal): Use it to
1840 decide whether all windows or frames should be updated.
1841 (window_outdated): New function.
1842 (text_outside_line_unchanged_p, redisplay_window): Use it.
1843 (redisplay_internal): Likewise. Fix indentation.
1844
1845 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1846
1847 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1848 (syms_of_eval): Remove corresponding defsubr.
1849 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1850
1851 2012-11-19 Daniel Colascione <dancol@dancol.org>
1852
1853 * w32fns.c (Fx_file_dialog):
1854 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1855 cygwin_convert_file_name*.
1856
1857 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1858 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1859
1860 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1861
1862 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1863
1864 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1865
1866 * w32select.c: Include w32common.h before w32term.h, so that
1867 windows.h gets included before w32term.h uses some of its
1868 features, see below.
1869
1870 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1871 New typedefs.
1872 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1873 New prototypes.
1874 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1875
1876 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1877
1878 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1879 (ns_select): Return at once if events are held (Bug#12834).
1880
1881 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1882
1883 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1884 Needed following 2012-10-20 change. (Bug#12902)
1885
1886 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1887
1888 * w32proc.c (waitpid): Remove unused label get_result.
1889
1890 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1891
1892 * makefile.w32-in (SYSWAIT_H): New macro.
1893 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1894 ($(BLD)/sysdep.$(O)): Update dependencies.
1895
1896 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1897
1898 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1899 * callproc.c (relocate_fd): Assume F_DUPFD.
1900 * emacs.c, term.c (O_RDWR): Remove.
1901 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1902 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1903 * nsterm.m: Assume <fcntl.h> exists.
1904 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1905 (create_pty, Fmake_network_process, server_accept_connection)
1906 (wait_reading_process_output, init_process_emacs):
1907 Assume O_NONBLOCK.
1908 (wait_reading_process_output): Put in a special case for WINDOWSNT
1909 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1910 It's not clear this is needed, but it's a more-conservative change.
1911 (create_process): Assume FD_CLOEXEC.
1912 (create_process, create_pty): Assume O_NOCTTY.
1913 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1914 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1915 Omit if not DOS_NT, since F_GETFL is not defined there.
1916 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1917 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1918 (O_NOCTTY): Remove.
1919 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1920 lack it, since gnulib guarantees this.
1921 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1922
1923 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1924
1925 * w32.c (faccessat): Pretend that directories have the execute bit
1926 set. Emacs expects that, e.g., in files.el:cd-absolute.
1927
1928 * w32proc.c (create_child): Don't clip the PID of the child
1929 process to fit into an Emacs integer, as this is no longer a
1930 restriction.
1931 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1932 reaping only the process specified by PID argument, if that is
1933 positive. Use PID instead of dead_child to know which process to
1934 reap. Wait for the child to die only if WNOHANG is not in
1935 OPTIONS.
1936 (sys_select): Don't set dead_child.
1937
1938 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1939 as it is no longer needed.
1940
1941 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1942 no longer needed.
1943 (record_child_status_change): Remove the setting of
1944 record_at_most_one_child for the !WNOHANG case.
1945
1946 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1947
1948 Fix problems in ns port found by static checking.
1949 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1950 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1951 not to process group.
1952 (ns_select): Use emacs_write, not write, as that's more robust
1953 in the presence of signals.
1954 (fd_handler:): Check for read errors.
1955
1956 2012-11-16 Glenn Morris <rgm@gnu.org>
1957
1958 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1959
1960 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1961
1962 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1963
1964 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1965
1966 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1967 use the same value of thread handle.
1968 (start_timer_thread): If the timer thread exited (due to error),
1969 clean up by closing the two handles it used. Duplicate the caller
1970 thread's handle here, so it gets duplicated only once, when
1971 launching the timer thread. Set priority of the timer thread, not
1972 the caller thread.
1973 (getitimer): Don't duplicate the caller thread's handle here.
1974 (Bug#12832)
1975
1976 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1977
1978 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1979 called (Bug#12834).
1980
1981 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1982
1983 Remove no-longer-used pty_max_bytes variable.
1984 * process.c (pty_max_bytes): Remove; unused.
1985 (send_process): Do not set it.
1986
1987 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1988
1989 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1990 Update dependencies.
1991
1992 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1993
1994 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1995 This follows up on the 2012-09-29 patch that removed indirection
1996 for the 'function' field. Reported by Sergey Vinokurov in
1997 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1998
1999 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2000
2001 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2002 different name, as the MS runtime does not have such a function,
2003 and probably never will.) All callers changed. Ignore DIRFD
2004 value if PATH is an absolute file name, to match Posix spec
2005 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2006 symlinks.
2007
2008 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2009
2010 * xdisp.c (echo_area_display, redisplay_internal):
2011 Omit redundant check whether frame_garbaged is set.
2012
2013 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2014
2015 Use faccessat, not access, when checking file permissions (Bug#12632).
2016 This fixes a bug that has been present in Emacs since its creation.
2017 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2018 which must set some sort of record. (Torek's bug report was against
2019 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2020 same common flaw.) See Torek's Usenet posting
2021 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2022 Posted: Fri Apr 8 14:18:56 1983.
2023 * Makefile.in (LIB_EACCESS): New macro.
2024 (LIBES): Use it.
2025 * callproc.c (init_callproc):
2026 * charset.c (init_charset):
2027 * fileio.c (check_existing, check_executable, check_writable)
2028 (Ffile_readable_p):
2029 * lread.c (openp, load_path_check):
2030 * process.c (allocate_pty):
2031 * xrdb.c (file_p):
2032 Use effective UID when checking permissions, not real UID.
2033 * callproc.c (init_callproc):
2034 * charset.c (init_charset):
2035 * lread.c (load_path_check, init_lread):
2036 Test whether directories are accessible, not merely whether they exist.
2037 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2038 * fileio.c (check_existing, check_executable, check_writable)
2039 (Ffile_readable_p):
2040 Use symbolic names instead of integers for the flags, as they're
2041 portable now.
2042 (check_writable): New arg AMODE. All uses changed.
2043 Set errno on failure.
2044 (Ffile_readable_p): Use faccessat, not stat + open + close.
2045 (Ffile_writable_p): No need to call check_existing + check_writable.
2046 Just call check_writable and then look at errno. This saves a syscall.
2047 dir should never be nil; replace an unnecessary runtime check
2048 with an eassert. When checking the parent directory of a nonexistent
2049 file, check that the directory is searchable as well as writable, as
2050 we can't create files in unsearchable directories.
2051 (file_directory_p): New function, which uses 'stat' on most platforms
2052 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2053 (Ffile_directory_p, Fset_file_times): Use it.
2054 (file_accessible_directory_p): New function, which uses a single
2055 syscall for efficiency.
2056 (Ffile_accessible_directory_p): Use it.
2057 * xrdb.c (file_p): Use file_directory_p.
2058 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2059 * lread.c (openp): When opening a file, use fstat rather than
2060 stat, as that avoids a permissions race. When not opening a file,
2061 use file_directory_p rather than stat.
2062 (dir_warning): First arg is now a usage string, not a format.
2063 Use errno. All uses changed.
2064 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2065 that merely introduced a race.
2066 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2067 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2068 and similarly for the other O_* flags.
2069 * w32.c (sys_faccessat): Rename from sys_access and switch to
2070 faccessat's API. All uses changed.
2071 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2072 (magic_db): Rename from magic_file_p.
2073 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2074 char *, so that we don't have to test for file existence
2075 separately from opening the file for reading. This removes a race
2076 fixes a permission-checking problem, and simplifies the code.
2077 All uses changed.
2078 (file_p): Remove; no longer needed.
2079
2080 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2081
2082 Omit glyphs initialization at startup.
2083 * dispnew.c (glyphs_initialized_initially_p): Remove.
2084 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2085 (Fredraw_frame): Move actual code from here...
2086 (redraw_frame): ...to here. Add eassert. Adjust comment.
2087 (Fredraw_display): Use redraw_frame.
2088 * xdisp.c (clear_garbaged_frames): Likewise.
2089
2090 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2091
2092 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2093 passed to pint2str and pint2hrstr to be at most the size of the
2094 frame's decode_mode_spec_buffer. This avoids crashes with very
2095 large values of FIELD_WIDTH argument to decode_mode_spec.
2096 (Bug#12867)
2097
2098 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2099
2100 Fix a race with verify-visited-file-modtime (Bug#12863).
2101 Since at least 1991 Emacs has ignored an mtime difference of no
2102 more than one second, but my guess is that this was to work around
2103 file system bugs that were fixed long ago. Since the race is
2104 causing problems now, let's remove that code.
2105 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2106 whose time stamp is off by no more than a second. Insist that the
2107 file time stamps match exactly.

2167 point is positioned many lines beyond the window top/bottom.
2168 (Bug#12811)
2169
2170 * ralloc.c (relinquish): If real_morecore fails to return memory
2171 to the system, don't crash; instead, leave the last heap

2201
2202 Tweak last vectorlike_header change.
2203 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2204 vectorlike object on the free list. This is introduced to avoid

2210
2211 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2212
2213 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has

2287 value of w32-scroll-lock-modifier is neither nil nor one of the
2288 known key modifiers. (Bug#12806)
2289
2290 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>

2343
2344 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2345
2346 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2347 such as Scroll Lock, if the respective keys are treated as
2348 function keys, not as modifiers. This avoids destroying non-ASCII
2349 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2350
2351 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2352
2353 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.

2355 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2356
2357 Restore some duplicate definitions (Bug#12814).
2358 This undoes part of the 2012-11-03 changes. Some people build
2359 with plain -g rather than with -g3, and they need the duplicate
2360 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2361 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2362 Define as macros, as well as as enums or as constants.
2363

2367 to keypad keys (Bug#12816).
2368
2369 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2370
2371 Minor adjustments of recently-changed frame functions.
2372 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2373 known to be a frame (we're in the FRAMEP branch).
2374 * lisp.h (Qframep): Remove decl. frame.h declares this.
2375 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2376 since they're meant for Lisp fixnum values.
2377
2378 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2379
2380 * window.c (Fwindow_combination_limit): Revert to the only
2381 required argument and adjust docstring as suggested in
2382 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2383 by Martin Rudalics <rudalics@gmx.at>.
2384
2385 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

2431
2432 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2433
2434 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2435
2436 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2437 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2438 file descriptor 2 for standard error. (Bug#12805)
2439
2440 2012-11-05 Chong Yidong <cyd@gnu.org>
2441
2442 * process.c (wait_reading_process_output): Revert previous change.
2443
2444 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2445
2446 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2447 This removes code that has been obsolete since around 1990.
2448 * callproc.c (Fcall_process):
2449 * emacs.c (main):
2450 * process.c (create_process):
2451 * term.c (dissociate_if_controlling_tty):
2452 Assume setsid exists.
2453 * callproc.c (child_setup): Assume setpgid exists and behaves as
2454 per POSIX.1-1988 or later.
2455 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2456 * emacs.c (shut_down_emacs):
2457 * sysdep.c (sys_suspend, init_foreground_group):
2458 Assume getpgrp behaves as per POSIX.1-1998 or later.
2459 * msdos.c (setpgrp): Remove.
2460 (tcgetpgrp, setpgid, setsid): New functions.
2461 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2462 * term.c (no_controlling_tty): Remove; unused.
2463 * w32proc.c (setpgrp): Remove.
2464 (setsid, tcgetpgrp): New functions.
2465
2466 Simplify by assuming __fpending.
2467 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2468 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2469 Do not assume that __fpending's result fits in int.
2470
2471 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2472
2473 Remove EMACS_OUTQSIZE+sleep hack.
2474 * dispnew.c (update_frame_1): Remove hack for terminals slower
2475 than 2400 bps, which throttled Emacs by having it sleep.
2476 This code hasn't worked since at least 2007, when the multi-tty stuff
2477 was added, and anyway those old terminals are long dead.
2478 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2479 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2480
2481 Fix data-loss with --version (Bug#9574).
2482 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2483 as we can't assume that emacs_strerror is initialized, and strerror
2484 is good enough here.
2485 (main): Invoke atexit earlier, to catch earlier instances of
2486 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2487
2488 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2489
2490 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).

2493 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2494
2495 Fix data-loss with --batch (Bug#9574).
2496 * emacs.c: Include <close-stream.h>.
2497 (close_output_streams): New function.
2498 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2499 and handles errors appropriately.
2500 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2501 does that now.
2502
2503 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2504 The symptom is a diagnostic "GLib-WARNING **: In call to
2505 g_spawn_sync(), exit status of a child process was requested but
2506 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2507 waitpid(), so exit status can't be returned." The diagnostic
2508 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2509 The real bug is a race condition between Emacs and glib: Emacs
2510 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2511 so that glib can't find it. Work around the bug by invoking
2512 waitpid only on subprocesses that Emacs itself creates.
2513 * process.c (create_process, record_child_status_change):
2514 Don't use special value -1 in pid field, as the caller now must
2515 know the pid rather than having the callee infer it.
2516 The inference was sometimes incorrect anyway, due to another race.
2517 (create_process): Set new 'alive' member if child is created.
2518 (process_status_retrieved): New function.
2519 (record_child_status_change): Use it.
2520 Accept negative 1st argument, which means to wait for the
2521 processes that Emacs already knows about. Move special-case code
2522 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2523 processes that have already been waited for, by testing and
2524 clearing new 'alive' member.
2525 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2526 now does this internally.
2527 (handle_child_signal): Let record_child_status_change do all
2528 the work, since we do not want to reap all exited child processes,
2529 only the child processes that Emacs itself created.
2530 * process.h (Lisp_Process): New boolean member 'alive'.
2531
2532 Omit duplicate definitions no longer needed with gcc -g3.
2533 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2534 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2535 Define only as macros. There's no longer any need to also define
2536 these symbols as enums or as constants, since we now assume
2537 gcc -g3 when debugging.
2538
2539 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2540
2541 * lisp.mk: Adjust comments to the fact that term/internal is now
2542 loaded from loadup.el.
2543
2544 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2545 (msdos_fatal_signal): New function.
2546 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2547 its argument list.
2548
2549 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2550 for GCC versions before 4.
2551 (emacs_raise): Define to call msdos_fatal_signal.
2552
2553 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2554 iterator when starting in the middle of a display or overlay
2555 string. (Bug#12745)
2556
2557 2012-11-03 Chong Yidong <cyd@gnu.org>
2558
2559 * process.c (wait_reading_process_output): Clean up the last
2560 change.
2561
2562 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2563
2564 * process.c (wait_reading_process_output): Avoid a race condition
2565 with SIGIO delivery (Bug#11536).
2566
2567 2012-11-03 Chong Yidong <cyd@gnu.org>
2568
2569 * buffer.c (cursor_type): Untabify docstring.
2570
2571 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2572
2573 * frame.h (struct frame): Drop can_have_scroll_bars member
2574 which is meaningless for a long time. Adjust comments.
2575 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2576 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2577
2578 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2579
2580 * window.c (decode_next_window_args): Update window arg after
2581 calling decode_live_window and so fix crash reported at
2582 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2583 by Juanma Barranquero <lekktu@gmail.com>.
2584 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2585 * font.c (Ffont_at): Likewise.
2586
2587 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2588
2589 * widget.c (resize_cb): New function.
2590 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2591 (EmacsFrameResize): Check if all is up to date before changing frame
2592 size.
2593
2594 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2595
2596 Implement backtrace output for fatal errors on MS-Windows.
2597 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2598 (BACKTRACE_LIMIT_MAX): New macro.
2599 (w32_backtrace): New function.
2600 (emacs_abort): Use w32_backtrace when the user chooses not to
2601 attach a debugger. Update the text of the abort dialog.
2602
2603 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2604
2605 Window-related stuff cleanup here and there.
2606 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2607 Use decode_any_window.
2608 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2609 * xdisp.c (Fformat_mode_line): Likewise.
2610 * font.c (Ffont_at): Use decode_live_window.
2611 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2612 * window.c (decode_next_window_args): Likewise.
2613 (decode_any_window): Remove static.
2614 * window.h (decode_any_window): Add prototype.
2615 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2616 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2617 respectively.
2618
2619 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2620
2621 Remove pad from struct input_event.
2622 * termhooks.h (struct input_event): Remove padding field.
2623 Adjust comment.
2624 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2625 member is never cons for a long time. Adjust comment.
2626 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2627 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2628 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2629 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2630
2631 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2632
2633 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2634
2635 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2636
2637 Fix crash when using Emacs as commit editor for git (Bug#12697).
2638 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2639 and it is configured in conf_post.h.
2640 (Fcall_process): Don't invoke both setsid and setpgid; the former
2641 is enough, if it exists.
2642 * callproc.c (Fcall_process, child_setup):
2643 * process.c (create_process): Use setpgid.
2644 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2645 for the real thing.
2646 * dispnew.c (init_display): Initialize the foreground group
2647 if we are running a tty display.
2648 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2649 * lisp.h (init_foreground_group): New decl.
2650 * sysdep.c (inherited_pgroup): New static var.
2651 (init_foreground_group, tcsetpgrp_without_stopping)
2652 (narrow_foreground_group, widen_foreground_group): New functions.
2653 (init_sys_modes): Narrow foreground group.
2654 (reset_sys_modes): Widen foreground group.
2655
2656 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2657
2658 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2659
2660 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2661
2662 * minibuf.c (read_minibuf): Restore current buffer since
2663 choose_minibuf_frame calling Fset_frame_selected_window may
2664 change it (Bug#12766).
2665
2666 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2667
2668 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2669
2670 2012-10-30 Kenichi Handa <handa@gnu.org>
2671
2672 * font.c (Ffont_at): If WINDOW is specified and it is not
2673 displaying the current buffer, signal an error.
2674
2675 2012-10-29 Daniel Colascione <dancol@dancol.org>
2676
2677 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2678 In preparation for fixing bug#12739, move these functions from
2679 here...
2680
2681 * coding.h, coding.c: ... to here, and compile them only when
2682 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2683 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2684
2685 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2686
2687 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2688 (timer_loop, getitimer, setitimer): Use it instead of
2689 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2690 'clock'.
2691 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2692 literal 10000.
2693
2694 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2695
2696 * nsterm.m (NO_APPDEFINED_DATA): New define.
2697 (last_appdefined_event_data): New variable
2698 (last_appdefined_event): Remove.
2699 (ns_select): Initialize t from last_appdefined_event_data instead
2700 of [last_appdefined_event data1].
2701 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2702 remove last_appdefined_event (Bug#12698).
2703
2704 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2705
2706 * frame.c (x_set_font): Catch internal error.
2707
2708 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2709
2710 Avoid overflow in w32 implementation of interval timers.
2711 When possible, for ITIMER_PROF count only times the main thread
2712 actually executes.
2713 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2714 'volatile ULONGLONG' types. All the other data which was
2715 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2716 (GetThreadTimes_Proc): New typedef.
2717 (w32_get_timer_time): New function, returns a suitable time value
2718 for the timer.
2719 (timer_loop): Enter critical section when accessing ULONGLONG
2720 values of the itimer_data struct, as these accesses are no longer
2721 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2722 Remove unused variable.
2723 (init_timers): Initialize s_pfn_Get_Thread_Times.
2724 (start_timer_thread): Don't assign itimer->caller_thread here.
2725 (getitimer): Assign itimer->caller_thread here.
2726 (setitimer): Always call getitimer to get the value of ticks_now.
2727 (sys_spawnve): Avoid compiler warning about format mismatch.
2728
2729 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2730
2731 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2732 mouse movement events if the menu bar is active. This avoids
2733 producing a busy "hour-glass" cursor by Windows if the mouse
2734 pointer is positioned over a tooltip shown for some menu item.
2735
2736 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2737
2738 Don't assume process IDs fit in int.
2739 * emacs.c (shut_down_emacs) [!DOS_NT]:
2740 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2741 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2742 Use pid_t, not int, to store process IDs, as 'int'
2743 is not wide enough on a few platforms (e.g., AIX and IRIX).
2744
2745 2012-10-23 Kenichi Handa <handa@gnu.org>
2746
2747 The following change is to make face-font-rescale-alist work
2748 correctly for non-ASCII fonts.
2749
2750 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2751 (font_open_for_lface): Handle Vface_font_rescale_alist.
2752
2753 2012-10-23 Chong Yidong <cyd@gnu.org>
2754
2755 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2756
2757 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2758
2759 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2760 for screen font.
2761 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2762
2763 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2764 event (Bug#12681).
2765
2766 2012-10-21 Glenn Morris <rgm@gnu.org>
2767
2768 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2769
2770 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2771
2772 Port to OpenBSD 5.1.
2773 * frame.c (Fmouse_position, Fmouse_pixel_position):
2774 * xdisp.c (produce_stretch_glyph):
2775 Declare local vars only when they're needed.
2776 This is clearer and avoids a warning on OpenBSD about unused vars.
2777 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2778 This is safer, and avoids OpenBSD warnings about unused vars.
2779 * keyboard.c (record_menu_key): Remove unnecessary decl.
2780 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2781 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2782 as our definition clashes with OpenBSD's.
2783 * xfaces.c (load_face_colors, check_lface_attrs)
2784 (get_lface_attributes_no_remap, get_lface_attributes)
2785 (lface_fully_specified_p, x_supports_face_attributes_p)
2786 (tty_supports_face_attributes_p, face_fontset, realize_face)
2787 (realize_x_face, realize_tty_face):
2788 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2789 merely Lisp_Object *. This is more informative and avoids
2790 a warning on OpenBSD about accessing beyond an object's size.
2791
2792 2012-10-20 Chong Yidong <cyd@gnu.org>
2793
2794 * lread.c (Fload): Doc fix (Bug#12592).
2795

2803 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2804 for the reasons.
2805
2806 * alloc.c (NSTATICS): Decrease to 0x800.
2807
2808 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
2809
2810 * fns.c (Fnreverse): Include the problem element when signaling an
2811 error (bug#12677).
2812
2813 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2814
2815 * nsterm.m (ns_select): Check writefds before call to
2816 FD_ISSET (Bug#12668).
2817
2818 2012-10-18 Daniel Colascione <dancol@dancol.org>
2819
2820 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2821 (staticpro): If we run out of staticpro slots, die with an
2822 informative error instead of just calling emacs_abort.
2823
2824 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2825
2826 Fix two flaws reported by Dmitry Antipov.

2829 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
2830
2831 2012-10-17 Eli Zaretskii <eliz@gnu.org>
2832
2833 * makefile.w32-in ($(BLD)/w32.$(O)):
2834 ($(BLD)/vm-limit.$(O)):
2835 ($(BLD)/term.$(O)):
2836 ($(BLD)/unexw32.$(O)):
2837 ($(BLD)/fileio.$(O)):

2856
2857 * unexw32.c: Include lisp.h and w32.h.

2864
2865 * dispnew.c [WINDOWSNT]: Include w32.h.
2866
2867 * cygw32.c (Fcygwin_convert_path_to_windows)

2869 Lisp_Object values. (Bug#12661)
2870
2871 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
2872 to Lisp_Object. (Bug#12661)
2873
2874 2012-10-17 Kenichi Handa <handa@gnu.org>
2875
2876 * xdisp.c (reseat_1): Make the information stored in it->cmp_it
2877 invalidate.

2880
2881 * buffer.c (Fkill_buffer): When unchaining the marker,
2882 reset its buffer pointer to NULL (Bug#12652).
2883
2884 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
2885
2886 Do not verify indirection counters of killed buffers (Bug#12579).
2887 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
2888 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
2889

2899 * editfns.c (get_system_name): Remove.
2900 * lisp.h (get_system_name): Remove prototype.
2901 * xrdb.c (getenv, getpwuid, getpwnam): Remove prototypes.
2902 (get_environ_db): Use Vsystem_name. Avoid call to strlen.
2903
2904 2012-10-15 Daniel Colascione <dancol@dancol.org>
2905
2906 * dbusbind.c: Add comment explaining reason for previous change.
2907
2908 2012-10-15 Martin Rudalics <rudalics@gmx.at>
2909
2910 * window.c (Fwindow_end): Rewrite check whether cached position
2911 can be used (Bug#12600).
2912 (resize_frame_windows, grow_mini_window, shrink_mini_window):
2913 Set windows_or_buffers_changed.

2918 enabled by undefining the symbol "interface", which the platform
2919 headers define to something incompatible.
2920

2928
2929 * nsterm.m (ns_select): Count fd:s in writefs also (Bug#12422).

2942 * fileio.c: Formatting fixes.
2943
2944 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
2945
2946 Fix some stat-related races.
2947 * fileio.c (Fwrite_region): Avoid race condition if a file is
2948 removed or renamed by some other process immediately after Emacs
2949 writes it but before Emacs stats it. Do not assume that stat (or
2950 fstat) succeeds.
2951 * image.c (slurp_file): Resolve the file name with fopen + fstat
2952 rather than stat + fopen.
2953 (pbm_read_file) [0]: Remove unused code with stat race.

2968 return (Bug#12384).
2969 (setPosition:portion:whole:): Send SIGIO to ourselves if apploopnr
2970 is zero (Bug#12384).

2979
2980 * fileio.c (check_existing): New function.
2981 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
2982 instead of calling 'stat', when what's needed is to check whether
2983 a file exists. This avoids expensive system calls on MS-Windows.
2984 (Bug#12587)
2985
2986 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
2987
2988 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
2989 determine whether a file exists and is not a directory.
2990
2991 * lisp.h (check_existing): Add prototype.
2992
2993 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
2994

2996
2997 2012-10-12 Glenn Morris <rgm@gnu.org>
2998

3000
3001 2012-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
3002
3003 * buffer.c (Fkill_buffer): Null out the overlay list(s) as well.
3004
3005 * eval.c (Fautoload): Remember previous autoload status in load-history.

3022 (ns_menu_show):
3023 * xmenu.c (set_frame_menubar, create_and_show_popup_menu)
3024 (xmenu_show, xdialog_show):
3025 Use bool for booleans.
3026 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
3027 as it's not a predicate. All uses changed. Omit unnecessary
3028 buffer termination.
3029
3030 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
3031
3032 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.

3049 (waiting_for_input, echoing, immediate_quit, input_pending)
3050 (interrupt_input, interrupts_deferred, pop_kboard)
3051 (temporarily_switch_to_single_kboard, ignore_mouse_drag_p)
3052 (command_loop_1, adjust_point_for_property)

3070 (Fdescribe_buffer_bindings, describe_map_tree, struct describe_map_elt)
3071 (describe_map, describe_vector):
3072 * menu.c (single_menu_item):
3073 * nsmenu.m (ns_update_menubar):
3074 * process.c (wait_reading_process_output):
3075 * search.c (scan_buffer, scan_newline):
3076 Use bool for boolean.
3077 * keyboard.c (timers_run, swallow_events)
3078 (detect_input_pending_run_timers):
3079 * process.c (wait_reading_process_output):
3080 Use unsigned for counter where wraparound-on-overflow is desired,
3081 since unsigned is guaranteed to have that behavior and signed is not.
3082 (read_char): Use ptrdiff_t for string length.
3083 (get_input_pending): Remove first argument, since it was always
3084 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3085 and behave as if it had that value. Return new value of
3086 input_pending. All callers changed.
3087 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3088 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
3089 a string length.
3090 * keymap.c (push_key_description): Omit last arg, which was always 1.
3091 All callers changed.
3092
3093 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
3094
3095 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

3108 Clean out old termopts cruft.
3109 * termopts.h (flow_control, meta_key): Remove unused decls.
3110 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
3111 Don't include termopts.h.
3112
3113 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3114
3115 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3116
3117 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3118
3119 * commands.h (immediate_quit): Remove duplicate decl.
3120
3121 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3122
3123 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
3124 caching.
3125 (nsfont_open): Remove setting of Vfonts_in_cache.
3126 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3127
3128 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3129
3130 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3131 match what GetLastError returns. Explain why the function is
3132 needed.
3133
3134 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3135 'is_tooltip_frame', to avoid confusion with its global namesake.
3136
3137 2012-10-08 Daniel Colascione <dancol@dancol.org>
3138
3139 * xdisp.c (start_hourglass): Call w32_note_current_window when
3140 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3141 build that caused Emacs to display the hourglass cursor forever.
3142
3143 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3144 which is broken under remote desktop, calculate the number of
3145 colors available for a display based on the display's number of
3146 planes and number of bits per pixel per plane. (bug#10397).
3147
3148 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3149
3150 * nsfont.m (Vfonts_in_cache): New variable.
3151 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3152 are used. Add cached fonts to Vfonts_in_cache.
3153 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3154
3155 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3156
3157 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3158 in nt/config.nt.
3159 (FONT_H): Define after FRAME_H.
3160 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3161 Update dependencies.
3162
3163 * w32term.c: Remove leftover declaration of keyboard_codepage.
3164
3165 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3166
3167 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3168 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3169 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3170 (GLOBAL_SOURCES): Add cygw32.c.
3171 ($(BLD)/unexw32.$(O)):
3172 ($(BLD)/w32.$(O)):
3173 ($(BLD)/w32console.$(O)):
3174 ($(BLD)/w32fns.$(O)):
3175 ($(BLD)/w32heap.$(O)):
3176 ($(BLD)/w32menu.$(O)):
3177 ($(BLD)/w32proc.$(O)): Add w32common.h.
3178
3179 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3180 'const char *'.
3181 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3182
3183 2012-10-08 Daniel Colascione <dancol@dancol.org>
3184
3185 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3186 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3187 accidental message numbering hole. Change other messages to
3188 match.
3189
3190 * w32select.h (HAVE_W32SELECT): Remove.
3191
3192 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3193 w32common.h instead of w32heap.h.
3194
3195 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3196 (get_allocation_unit, get_processor_type, get_w32_major_version)
3197 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3198 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3199 (OS_NT, os_subtype, cache_system_info): Move declarations to
3200 w32common.
3201
3202 * w32heap.c: Include w32common.h.
3203 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3204 (w32_minor_version, w32_build_number, w32_subtype):
3205 Remove duplicate definitions.
3206
3207 * w32fns.c: Include w32common.h; include w32heap.h only in
3208 WINDOWSNT.
3209
3210 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3211 Use `report_file_error' instead of `error' in order to better
3212 inform users of what went wrong. Increase NTGUI_UNICODE file
3213 dialog box file name length to 32k, the maximum allowed by the NT
3214 kernel.
3215
3216 * w32common.h: New file.
3217 (ROUND_UP, ROUND_DOWN, get_page_size)
3218 (get_allocation_unit, get_processor_type, get_w32_major_version)
3219 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3220 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3221 (OS_NT, os_subtype, cache_system_info): Move here.
3222
3223 * unexw32.c, unexcw.c: Include w32common.h.
3224
3225 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3226 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3227 to call syms_of_w32select.
3228
3229 * cygw32.h: Remove obsolete EXFUN declarations.
3230
3231 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3232
3233 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3234 of w32inevt.o from SOME_MACHINE_OBJECTS.
3235
3236 2012-10-08 Daniel Colascione <dancol@dancol.org>
3237
3238 * image.c: Permanent fix for JPEG compilation issue --- limit
3239 jpeglib `boolean' redefinition to Cygwin builds.
3240
3241 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3242
3243 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3244
3245 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3246 Cygwin.
3247
3248 2012-10-08 Daniel Colascione <dancol@dancol.org>
3249
3250 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3251 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3252 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3253 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3254 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3255 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3256 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3257 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3258 now a supported configuration.
3259
3260 * Makefile.in: consolidate image variables into LIBIMAGE; add
3261 W32_OBJ and W32_LIBS. Compile new files.
3262
3263 * conf_post.h:
3264 (_DebPrint) declare tracing facility for W32 debugging. We need
3265 to unify tracing later.
3266
3267 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3268 unconditional use of W32 Unicode functions. Cygwin runs only on
3269 100% Unicode operating systems.
3270
3271 * cygw32.c: New file. Define Cygwin-specific facilities.
3272 (Fcygwin_convert_path_to_windows)
3273 (Fcygwin_convert_path_from_windows): New user functions for
3274 accessing Cygwin path-munging routines.
3275
3276 * cygw32.h: New file.
3277 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3278 UTF-16LE strings temporarily inside non-Lisp-visible string
3279 objects.
3280
3281 (w32_strerror): Just what it says on the tin.
3282
3283 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3284 also run for Cygwin; both systems have the same problem with using
3285 GUI facilities in a forked child. Also call syms_of_cygw32,
3286 syms_of_w32select in correct places.
3287
3288 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3289 needs fork-then-exec for daemon launching.
3290
3291 * font.h: Include frame.h.
3292
3293 * image.c: Use the image library cache machinery only when we're
3294 compiling for native WINDOWSNT; Cygwin can use shared libraries
3295 like any other Unixlike system.
3296
3297 * keyboard.c: Clarify a comment regarding the input loop.
3298
3299 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3300 functions directly instead of trying to detect at runtime that our
3301 host operating system supports them. We make this change for two
3302 reasons: Cygwin lacks support for the multibyte character
3303 conversion functions used by the legacy menu code, and Cygwin
3304 never needs to rely on non-Unicode APIs.
3305
3306 * unexw32.c (hinst): Declare extern.
3307
3308 * w32.c: Change header order;
3309 (w32_strerror): Move to w32fns.c because we need it for
3310 non-WINDOWSNT builds.
3311
3312 * w32.h: Add #error macro to make sure we don't include w32.h for
3313 Cygwin builds. Remove w32select declarations.
3314
3315 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3316 w32fns.c. w32console.c is WINDOWSNT-only.
3317
3318 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3319 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3320 POSIXy alternative.
3321 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3322 (w32_major_version, w32_minor_version, w32_build_number)
3323 (os_subtype, sound_type): Define here
3324 (w32_defined_color): Make color parameter const for consistency
3325 with other _defined_color functions.
3326 (w32_createwindow): Unconditionally call w32_init_class instead of
3327 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3328 through the code is complex and unnecessary because class
3329 registration is practically free.
3330 (w32_name_of_message): New EMACSDEBUG-only function.
3331 (Fset_message_beep): Move here
3332 (Fx_open_connection): Require that the display name for Windows be
3333 "w32" for consistency, emacsclient disambiguation, and maybe, one
3334 day, multi-window-system support.
3335 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3336 Cygwin files for W32 GUI facilities, since these clearly don't
3337 expect Cygwin names.
3338 (_DebPrint): Define.
3339 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3340 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3341 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3342 (w32_last_error): Remove.
3343
3344 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3345
3346 * w32heap.c (syspage_mask): Declare here.
3347 (cache_system_info): Remove.
3348
3349 * w32inevt.c (faked_key): Define globally, not statically.
3350 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3351 (w32_console_toggle_lock_key): Move to w32fns.c.
3352
3353 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3354
3355 * w32proc.c (_DebPrint): Move to w32fns.c.
3356 * w32select.c: Include string.h, stdio.h for Cygwin.
3357 * w32select.h: New File.
3358
3359 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3360 get_osfhandle.
3361 (w32_message_fd): New variable. Under Cygwin, holds the file
3362 descriptor the system used to tell us about pending thread
3363 messages.
3364
3365 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3366 that prevented compilation under non-WINDOWSNT systems.
3367
3368 (w32_initialize): Open /dev/windows and assign it to
3369 w32_message_fd. Provide w32 feature.
3370
3371 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3372 (WM_EMACS_INPUT_READY): add.
3373 (prepend_msg, w32_message_fd): Declare globally.
3374
3375 * w32xfns.c:
3376 (keyboard_handle): Use only when WINDOWSNT.
3377 (notify_msg_ready): New function. Posts a message to the main
3378 thread's message queue under CYGWIN, which wakes up the main
3379 thread from select(2) by making the /dev/windows file descriptor
3380 ready. Under WINDOWSNT, it sets an event the same way the old
3381 code did.
3382
3383 (post, prepend_msg): Actually call notify_msg_ready instead of
3384 setting the input event directly.
3385
3386 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3387
3388 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3389 but it still has blocs in it, don't return it to the system,
3390 instead of aborting. (Bug#12402)
3391
3392 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3393
3394 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3395
3396 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3397 MAC_OS_X_VERSION_10_6.
3398 (syms_of_nsterm): Remove comment about Panther and above for
3399 ns-antialias-text.
3400 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

3418 Remove ns_in_resize check.
3419 (ns_clear_frame_area): Remove resize handle code.
3420
3421 * nsfns.m (ns_in_resize): Remove.
3422 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3423 Remove ns_in_resize check.
3424
3425 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3426
3427 Improve sys_siglist detection.
3428 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3429 defined as a macro, as is done in Solaris.
3430 (sys_siglist_entries): New macro.
3431 (save_strsignal): Use it.
3432 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3433 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3434
3435 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3436
3437 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3438 fullscreen/Fullscreen.
3439
3440 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3441 tobar_height is new.
3442
3443 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3444 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3445 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

3447 Capitalize word in comment. Remove incorrect comment.
3448 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3449 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3450 error in drawing background.
3451 (toggleFullScreen:): Remove comment. Rearrange calls.
3452 Set toolbar values to zero, save old height in tobar_height.
3453 Restore tool bar height when leaving fullscreen.
3454 (canBecomeMainWindow): New function.
3455
3456 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3457
3458 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3459
3460 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3461
3462 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3463
3464 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3465 that time stamps of directories could also be changed.
3466 Don't request the too broad GENERIC_WRITE, only the more restrictive
3467 FILE_WRITE_ATTRIBUTES access rights.
3468
3469 * fileio.c (Fset_file_times): Special-case ignoring errors for
3470 directories only on MSDOS, not on MS-Windows.
3471
3472 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3473
3474 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3475
3476 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3477
3478 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3479 see whether CreateFile failed.
3480
3481 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3482
3483 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3484 to avoid similar races.
3485 * keyboard.c (pending_signals): Now bool, not int.
3486
3487 Port timers to OpenBSD, plus check for timer failures.
3488 OpenBSD problem reported by Han Boetes.
3489 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3490 and/or setitimer.
3491 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3492 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3493 like OpenBSD, which has timer_settime but does not declare it.
3494 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3495 whether to use itimerspec-related primitives. All uses of
3496 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3497
3498 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3499
3500 * profiler.c (handle_profiler_signal): Fix a malloc race
3501 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3502
3503 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3504
3505 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3506
3507 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3508
3509 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3510 consistent with the change in return value of 'safe_strsignal'.
3511
3512 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3513
3514 Prefer plain 'static' to 'static inline' (Bug#12541).
3515 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3516 (bidi_set_sor_type, bidi_push_embedding_level)
3517 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3518 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3519 (bidi_cache_search, bidi_cache_ensure_space)
3520 (bidi_cache_iterator_state, bidi_cache_find)
3521 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3522 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3523 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3524 Now 'static', not 'static inline'.
3525
3526 Count overruns when profiling; change units to ns.
3527 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3528 Give extra weight to samples after overruns, to attempt to count
3529 the time more accurately.
3530 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3531 the underlying primitives nominally do ns.
3532 (Fprofiler_cpu_start): Document the change. Mention that
3533 the sampling intervals are only approximate.
3534
3535 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3536
3537 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3538
3539 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3540 case for the special 0 coding-system.
3541
3542 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3543 (Fmake_overlay): Remove redundant tests.
3544 (fix_start_end_in_overlays): Remove redundant recentering.
3545
3546 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3547
3548 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3549 Update dependencies.
3550
3551 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3552
3553 Fix a malloc race condition involving strsignal.
3554 A signal can arrive in the middle of a malloc, and Emacs's signal
3555 handler can invoke strsignal, which can invoke malloc, which is
3556 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3557 Fix it by altering the signal handler so that it does not invoke
3558 strsignal.
3559 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3560 * process.c (status_message): Use const pointer, in case strsignal
3561 is #defined to safe_strsignal.
3562 * sysdep.c (sys_siglist, init_signals): Always define and
3563 initialize a substitute sys_siglist if the system does not define
3564 one, even if HAVE_STRSIGNAL.
3565 (safe_strsignal): Rename from strsignal. Always define,
3566 using sys_siglist. Return a const pointer.
3567 * syssignal.h (safe_strsignal): New decl.
3568 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3569
3570 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3571
3572 * w32proc.c (timer_loop): Fix code that waits for timer
3573 expiration, to avoid high CPU usage.
3574
3575 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3576
3577 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3578 (sweep_weak_table): Remove redundant prototypes.
3579
3580 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3581
3582 * emacs.c: Move the inclusion of TERM_HEADER after including
3583 windows.h on WINDOWSNT. This avoids compilation problems with
3584 MSVC.
3585
3586 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3587
3588 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3589 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3590 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3591 as the previous version used 'void *'.
3592
3593 * ralloc.c (ROUNDUP): Fix last change.
3594 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3595 'size_t'.
3596
3597 * w32proc.c <disable_itimers>: New static flag.
3598 (init_timers): Initialize it to zero, after creating the critical
3599 sections used by the timer threads.
3600 (term_timers): Set to 1 before deleting the critical sections.
3601 (getitimer, setitimer): If disable_itimers is non-zero, return an
3602 error indication without doing anything. Reported by Fabrice
3603 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3604 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3605 return results.
3606 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3607 support timers.
3608
3609 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3610 term_ntproc after all the other bookkeeping, to get timers working
3611 as long as possible.
3612
3613 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3614
3615 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3616 Suggested by Juri Linkov in
3617 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3618
3619 Prefer plain 'static' to 'static inline' (Bug#12541).
3620 With static functions, modern compilers inline pretty well by
3621 themselves; advice from programmers often hurts as much as it helps.
3622 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3623 this change shrinks the text size of the Emacs executable by 1.1%
3624 without affecting CPU significantly in my benchmark.
3625 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
3626 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

3704 (bidi_copy_it): Do the whole copy with a single memcpy.
3705 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3706
3707 Revert the FOLLOW-SYMLINKS change for file-attributes.
3708 Doing it right would require several changes to Tramp, and there's
3709 not enough time to get that tested before the freeze today.
3710 * dired.c (directory_files_internal, Ffile_attributes):
3711 Undo last change.
3712
3713 * frame.c (x_report_frame_params): Port better to wider ints.
3714 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3715 or that pointers can be printed in 15 decimal digits.
3716 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3906
3907 Profiler improvements: more-accurate timers, overflow checks.
3908 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3909 signal.h, setjmp.h. Include systime.h instead.
3910 (saturated_add): New function.

3918 (handle_profiler_signal): Rename from sigprof_handler_1,
3919 for consistency with other handlers. Do not check whether
3920 cpu_log is a hash-table if garbage collecting, since it
3921 doesn't matter in that case.

3923 for consistency with other handlers.
3924 (setup_cpu_timer): New function, with much of what used to be in

3926 Prefer timer_settime if available, and prefer
3927 thread cputime clocks, then process cputime clocks, then
3928 monotonic clocks, to the old realtime clock. Use make_timeval
3929 to round more-correctly when falling back to setitimer.
3930 (Fprofiler_cpu_start): Use it.
3931 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3932 Don't assume that passing NULL as the 2nd argument of setitimer

3935 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3936 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3937 non-fatal signal handlers. Ignore SIGPROF on startup.
3938 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not

4147 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4148
4149 Move pid_t related decls out of lisp.h.
4150 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4151 (interruptible_wait_for_termination):
4152 Move these decls from lisp.h to syswait.h, since they use pid_t.
4153 Needed on FreeBSD; see Herbert J. Skuhra in
4154 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4155 * callproc.c: Include syswait.h.
4156
4157 gnutls.c, gtkutil.c: Use bool for boolean.
4158 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)
4159 (emacs_gnutls_handle_error):
4160 * gtkutil.c (xg_check_special_colors, xg_prepare_tooltip)

4169 (is_box_type, xg_tool_item_stale_p, xg_update_tool_bar_sizes)
4170 (update_frame_tool_bar, free_frame_tool_bar):
4171 * gtkutil.c, w32term.c, xterm.c (x_wm_set_size_hint):
4172 * nsmenu.m (ns_update_menubar):
4173 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4174 * xfns.c (Fx_show_tip) [USE_GTK]:
4175 Use bool for boolean.
4176 * gtkutil.c (xg_update_frame_menubar):
4177 * xmenu.c (update_frame_menubar):
4178 Return void, not int, since caller ignores return value.
4179 * gtkutil.c (xg_change_toolbar_position):
4180 Return void, not 1.
4181
4182 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4183
4184 * makefile.w32-in (BLOCKINPUT_H): Remove.

4200
4201 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4202
4203 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4204 fatal_error_backtrace.
4205
4206 * w32proc.c (sys_kill): Undo last change: don't do anything when
4207 invoked to deliver SIGABRT to our own process. This is now
4208 handled by emacs_raise.
4209
4210 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4211
4212 * w32term.c (w32_read_socket): Remove leftover reference to
4213 interrupt_input_pending.
4214
4215 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4216
4217 Do not use SA_NODEFER.
4218 Problem reported by Dani Moncayo in
4219 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4220 * alloc.c (die):
4221 * sysdep.c (emacs_abort): Do not reset signal handler.
4222 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4223 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4224 wanted even on POSIXish hosts, and it doesn't work on Windows.
4225
4226 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4227
4228 * xterm.c (x_term_init): Call fixup_locale before and after calling
4229 gtk_init (Bug#12392).
4230
4231 2012-09-23 Chong Yidong <cyd@gnu.org>
4232
4233 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4234 Vdynamic_library_alist.
4235
4236 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4237 (Fgnutls_available_p): Caller changed.
4238
4239 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4240 (Flibxml_parse_xml_region): Likewise.
4241
4242 * dispextern.h (struct image_type): Remove arg from init function.
4243
4244 * image.c (Finit_image_library, lookup_image_type)
4245 (define_image_type): Remove now-unneeded second arg.
4246 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4247 (init_tiff_functions, init_gif_functions, init_svg_functions):
4248 Arglist and w32_delayed_load calling convention changed.
4249 (gs_type): Remove init_gs_functions; there is no such function.
4250 (valid_image_p, make_image): Fix caller to lookup_image_type.
4251
4252 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4253
4254 Simplify and avoid signal-handling races (Bug#12471).
4255 * alloc.c (die):
4256 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4257 Avoid recursive loop if there's a fatal error in the function itself.
4258 * atimer.c (pending_atimers):
4259 * blockinput.h: Don't include "atimer.h"; no longer needed.
4260 (interrupt_input_pending): Remove. All uses removed.
4261 pending_signals now counts both atimers and ordinary interrupts.
4262 This is less racy than having three separate pending-signal flags.
4263 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4264 (input_blocked_p):
4265 Rename from their upper-case counterparts BLOCK_INPUT,
4266 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4267 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4268 This makes it easier to access volatile variables more accurately.
4269 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4270 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4271 that's more reliable if the code is buggy and sets
4272 interrupt_input_blocked to a negative value. All uses changed.
4273 * atimer.c (deliver_alarm_signal):
4274 Remove. No need to deliver this to the parent; any thread can
4275 handle this signal now. All uses replaced by underlying handler.
4276 * atimer.c (turn_on_atimers):
4277 * dispnew.c (handle_window_change_signal):
4278 * emacs.c (handle_danger_signal):
4279 * keyboard.c (kbd_buffer_get_event):
4280 Don't reestablish signal handler; not needed with sigaction.
4281 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4282 (UNBLOCK_INPUT_TO):
4283 Rework to avoid unnecessary accesses to volatile variables.
4284 (UNBLOCK_INPUT_TO): Now a function.
4285 (totally_unblock_input, unblock_input): New decls.
4286 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4287 (init_data): Remove. Necessary stuff now done in init_signal.
4288 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4289 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4290 (fatal_error_code): Remove; no longer needed.
4291 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4292 it doesn't always backtrace. All uses changed. No need to reset
4293 signal to default, since sigaction and/or die does that for us now.
4294 Use emacs_raise (FOO), not kill (getpid (), FOO).
4295 (main): Check more-accurately whether we're dumping.
4296 Move fatal-error setup to sysdep.c
4297 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4298 * gtkutil.c (xg_get_file_name, xg_get_font):
4299 Remove no-longer-needed signal-mask manipulation.
4300 * keyboard.c, process.c (POLL_FOR_INPUT):
4301 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4302 * keyboard.c (read_avail_input): Remove.
4303 All uses replaced by gobble_input.
4304 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4305 (kbd_buffer_store_event_hold, gobble_input):
4306 (record_asynch_buffer_change) [USABLE_SIGIO]:
4307 (store_user_signal_events):
4308 No need to mess with signal mask.
4309 (gobble_input): If blocking input and there are terminals, simply
4310 set pending_signals to 1 and return. All hooks changed to not
4311 worry about whether input is blocked.
4312 (process_pending_signals): Clear pending_signals before processing
4313 them, in case a signal comes in while we're processing.
4314 By convention callers now test pending_signals before calling us.
4315 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4316 New functions, to support changes to blockinput.h.
4317 (handle_input_available_signal): Now extern.
4318 (reinvoke_input_signal): Remove. All uses replaced by
4319 handle_async_input.
4320 (quit_count): Now volatile, since a signal handler uses it.
4321 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4322 All callers changed. Block SIGINT only if not already blocked.
4323 Clear sigmask reliably, even if Fsignal returns, which it can.
4324 Omit unnecessary accesses to volatile var.
4325 (quit_throw_to_read_char): No need to restore sigmask.
4326 * keyboard.c (gobble_input, handle_user_signal):
4327 * process.c (wait_reading_process_output):
4328 Call signal-handling code rather than killing ourselves.
4329 * lisp.h: Include <float.h>, for...
4330 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4331 (pending_signals): Now volatile.
4332 (syms_of_data): Now const if IEEE floating point.
4333 (handle_input_available_signal) [USABLE_SIGIO]:
4334 (terminate_due_to_signal, record_child_status_change): New decls.
4335 * process.c (create_process): Avoid disaster if memory is exhausted
4336 while we're processing a vfork, by tightening the critical section
4337 around the vfork.
4338 (send_process_frame, process_sent_to, handle_pipe_signal)
4339 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4340 ignores SIGPIPE.
4341 (send_process): No need for setjmp/longjmp any more, since the
4342 SIGPIPE stuff is now gone. Instead, report an error if errno
4343 is EPIPE.
4344 (record_child_status_change): Now extern. PID and W are now args.
4345 Return void, not bool. All callers changed.
4346 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4347 Remove. All uses removed. This bug should be fixed now in a
4348 different way.
4349 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4350 and record the child status change directly. This avoids the
4351 need to futz with the signal mask.
4352 (process_fatal_action): Move here from emacs.c.
4353 (emacs_sigaction_flags): New function, containing
4354 much of what used to be in emacs_sigaction_init.
4355 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4356 caught by emacs, to make races less likely.
4357 (deliver_process_signal): Rename from handle_on_main_thread.
4358 All uses changed.
4359 (BACKTRACE_LIMIT_MAX): Now at top level.
4360 (thread_backtrace_buffer, threadback_backtrace_pointers):
4361 New static vars.
4362 (deliver_thread_signal, deliver_fatal_thread_signal):
4363 New functions, for more-accurate delivery of thread-specific signals.
4364 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4365 (deliver_arith_signal): Handle in this thread, not
4366 in the main thread, since it's triggered by this thread.
4367 (maybe_fatal_sig): New function.
4368 (init_signals): New arg DUMPING so that we can be more accurate
4369 about whether we're dumping. Caller changed.
4370 Treat thread-specific signals differently from process-general signals.
4371 Block all signals while handling fatal error; that's safer.
4372 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4373 on IEEE hosts.
4374 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4375 Ignore SIGPIPE unless batch.
4376 (emacs_backtrace): Output backtrace for the appropriate thread,
4377 which is not necessarily the main thread.
4378 * syssignal.h: Include <stdbool.h>.
4379 (emacs_raise): New macro.
4380 * xterm.c (x_connection_signal): Remove; no longer needed
4381 now that we use sigaction.
4382 (x_connection_closed): No need to mess with sigmask now.
4383 (x_initialize): No need to reset SIGPIPE handler here, since
4384 init_signals does this for us now.
4385
4386 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4387
4388 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4389 background rect may be larger (Bug#12245).
4390
4391 2012-09-23 Chong Yidong <cyd@gnu.org>
4392
4393 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4394
4395 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4396
4397 * .gdbinit: Just stop at fatal_error_backtrace.
4398 See Stefan Monnier's request in
4399 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4400 Remove no-longer-used query of system type.
4401
4402 2012-09-22 Chong Yidong <cyd@gnu.org>
4403
4404 * search.c (Freplace_match): Doc fix (Bug#12325).
4405

4407
4408 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4409 (Fline_end_position): Doc fix.
4410
4411 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4412
4413 2012-09-22 Chong Yidong <cyd@gnu.org>
4414
4415 * dispextern.h (struct image_type): Add new slot, storing a type
4416 initialization function.
4417
4418 * image.c (define_image_type): Call the image initializer function
4419 if it is defined. Arguments and return value changed.
4420 (valid_image_p, make_image): Callers changed.
4421 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4422 (gif_type, imagemagick_type, svg_type, gs_type):
4423 Add initialization functions.
4424 (Finit_image_library): Call lookup_image_type.
4425 (CHECK_LIB_AVAILABLE): Macro deleted.
4426 (lookup_image_type): Call define_image_type here, rather than via
4427 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4428 (syms_of_image): Move define_image_type calls for xbm_type and
4429 pbm_type to lookup_image_type.
4430
4431 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4432
4433 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4434 'idle_timers' from here ...
4435 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4436 lists, to avoid infloops when the timer does something stupid,
4437 like reinvoke itself with the same or smaller time-out.
4438 (Bug#12447)
4439
4440 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4441
4442 * window.c (Fsplit_window_internal): Handle only Qt value of
4443 Vwindow_combination_limit separately.

4453 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4454
4455 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4456 or that fprintf is async-signal-safe. POSIX doesn't require
4457 either assumption.
4458
4459 2012-09-22 Chong Yidong <cyd@gnu.org>
4460
4461 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers

4470
4471 * image.c (define_image_type): Avoid adding duplicate types to
4472 image_types (Bug#12463). Suggested by Jörg Walter.
4473
4474 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4475
4476 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4477 (print_load_command_name): Add case LC_DATA_IN_CODE.
4478 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4479
4480 2012-09-21 Glenn Morris <rgm@gnu.org>
4481
4482 * eval.c (Frun_hook_with_args_until_success)
4483 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4484
4485 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4486
4487 * fileio.c (Ffile_selinux_context): Only call freecon when
4488 lgetfilecon succeeded.
4489 (Fset_file_selinux_context): Likewise. (Bug#12444)
4490
4491 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4492
4493 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4494 reordering, locate the cursor by calling set_cursor_from_row; if
4495 that fails, clear the desired glyph matrix before returning a
4496 failure indication to the caller. Fixes leaving garbled display
4497 when fast scrolling with a down-key. (Bug#12403)
4498 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4499 scrolling through multibyte text.
4500
4501 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4502
4503 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4504 calling mark_vectorlike since that's the one that marks the window.
4505 (mark_discard_killed_buffers): Mark the final cdr.
4506 * window.h (struct window): Move prev/next_buffers to the
4507 non-standard fields.
4508 * window.c (make_window): Initialize prev/next_buffers manually.
4509
4510 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>

4518 * xterm.c (XTread_socket):
4519 Omit unused arg EXPECTED. All callers changed.
4520 (store_user_signal_events): Return void, not int, since callers no
4521 longer care about the return value. All uses changed.
4522
4523 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4524
4525 * w32gui.h (XParseGeometry): Do not declare.

4528
4529 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4530 Ignore 'expected'. See Eli Zaretskii in
4531 <http://bugs.gnu.org/12471#8> (last line).
4532
4533 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4534 (XParseGeometry): Now static. Substitute extremal values for
4535 values that are out of range.
4536
4537 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4538
4539 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4540
4541 * nsfns.m (XParseGeometry): Remove.
4542 (Fx_create_frame): Call x_set_offset to correctly interpret
4543 top_pos in geometry.
4544
4545 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4546 (Fx_parse_geometry): If there is a space in string, call
4547 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4548
4549 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4550
4551 * search.c (scan_buffer): Use character positions in calls to
4552 region_cache_forward and region_cache_backward, not byte
4553 positions. (Bug#12196)
4554
4555 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4556 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4557
4558 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4559 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4560 emacs_blocked_malloc, now deleted.
4561
4562 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4563
4564 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4565 The workaround was for improving performance on Solaris 2.4, but
4566 is getting in the way now. Emacs will still work if someone is
4567 still running Solaris 2.4 in a museum somewhere; Sun dropped
4568 support for Solaris 2.4 in 2003.
4569 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4570 * process.c (create_process) [HAVE_WORKING_VFORK]:
4571 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4572 since Emacs no longer uses vfork on that platform.
4573
4574 2012-09-17 Glenn Morris <rgm@gnu.org>
4575
4576 * emacs.c: Use COPYRIGHT.
4577
4578 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4579
4580 Remove configure's --without-sync-input option (Bug#12450).
4581 When auditing signal-handling in preparation for cleaning it up,
4582 I found that SYNC_INPUT has race conditions and would be a real
4583 pain to fix. Since it's an undocumented and deprecated
4584 configure-time option, now seems like a good time to remove it.
4585 Also see <http://bugs.gnu.org/11080#16>.
4586 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4587 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4588 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4589 (malloc_hysteresis):
4590 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4591 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4592 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4593 (dont_register_blocks, bytes_used_when_reconsidered)
4594 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4595 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4596 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4597 Remove. All uses removed.
4598 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4599 implementation, one that depends on whether the new macro
4600 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4601 is defined.
4602 * atimer.c (run_timers, handle_alarm_signal):
4603 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4604 (handle_async_input, process_pending_signals)
4605 (handle_input_available_signal, init_keyboard):
4606 * nsterm.m (ns_read_socket):
4607 * process.c (wait_reading_process_output):
4608 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4609 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4610 (emacs_write):
4611 * xterm.c (XTread_socket):
4612 Assume SYNC_INPUT.
4613 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4614 * eval.c (handling_signal): Remove. All uses removed.
4615 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4616 All uses replaced with the SYNC_INPUT version.
4617 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4618 Remove decls.
4619 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4620 Now static.
4621
4622 * font.c (Ffont_shape_gstring): Remove unused local.
4623
4624 2012-09-16 Glenn Morris <rgm@gnu.org>
4625
4626 * Makefile.in (clean): No longer run nextstep's clean.
4627
4628 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4629 (ns_frag): Remove.
4630 (ns-app): Move here from ns.mk, and simplify.
4631 (clean): Simplify nextstep entry.
4632 * ns.mk: Remove file.
4633
4634 2012-09-17 Kenichi Handa <handa@gnu.org>
4635
4636 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4637 not covert the last few charactes.
4638
4639 2012-09-16 Kenichi Handa <handa@gnu.org>
4640
4641 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4642 here, but just check the validity of glyphs in the glyph-string.
4643
4644 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4645
4646 * window.c (Fwindow_parameter, Fset_window_parameter):
4647 Accept any window as argument (Bug#12452).
4648
4649 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4650
4651 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4652 to ns_term_init to avoid memory leak.
4653
4654 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4655 explicit retain/release.
4656 (ns_term_init): Only allow one display. Initialize outerpool and
4657 ns_*_types.
4658
4659 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4660
4661 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4662 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4663 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4664 the Microsoft problem in a different way, by altering ../nt/config.nt.
4665
4666 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4667
4668 * w32xfns.c:
4669 * w32uniscribe.c:
4670 * w32term.c:
4671 * w32select.c:
4672 * w32reg.c:
4673 * w32proc.c:
4674 * w32menu.c:
4675 * w32inevt.c:
4676 * w32heap.c:
4677 * w32font.c:
4678 * w32fns.c:
4679 * w32console.c:
4680 * w32.c:
4681 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4682 by lisp.h. This completes removal of setjmp.h inclusion
4683 erroneously announced in the previous commit. (Bug#12446)
4684
4685 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4686 more accurate.
4687
4688 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4689 not defined as a macro. The latter happens on MS-Windows.
4690 (Bug#12446)
4691
4692 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4693
4694 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4695 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4696 Some instances of '#include <setjmp.h>' removed, if the
4697 only reason for the instance was because "lisp.h" was included.
4698 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4699 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4700 and _longjmp with the new symbols. Emacs already uses _setjmp if
4701 available, so this change affects only POSIXish hosts that have
4702 sigsetjmp but not _setjmp, such as some versions of Solaris and
4703 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4704 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4705 (png_load_body) [HAVE_PNG]:
4706 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4707 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4708 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4709 since PNG requires jmp_buf. This is the only exception to the
4710 general rule that we now use sys_setjmp and sys_longjmp.
4711 This exception is OK since this code does not change the signal
4712 mask or longjmp out of a signal handler.
4713
4714 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4715
4716 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4717 Include "syssignal.h", for 'main_thread'.
4718
4719 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4720
4721 Avoid out-of-range marker position (Bug#12426).
4722 * insdel.c (replace_range, replace_range_2):
4723 Adjust markers before overlays, as suggested by comments.
4724 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4725 Remove redundant check before calling offset_intervals.
4726
4727 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4728
4729 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4730 current buffer (Bug#12387).
4731
4732 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4733
4734 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4735
4736 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4737
4738 Use a more backwards-compatible timer format (Bug#12430).
4739 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4740 vector element, not from the 4th, since PSECS is now at the end.
4741 (Fcurrent_idle_time): Doc fix.
4742
4743 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4744
4745 Function to mark objects and remove killed buffers at once.
4746 * alloc.c (discard_killed_buffers): Rename to ...
4747 (mark_discard_killed buffers) ... new name. Add marking
4748 of remaining objects. Fix comment. Adjust users.
4749 (mark_object): Do not touch frame buffer lists here.
4750 * frame.c (delete_frame): Reset frame buffer lists here.
4751
4752 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4753
4754 Better workaround for GNOME bug when --enable-gcc-warnings.
4755 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4756 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4757 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4758
4759 Simplify SIGIO usage (Bug#12408).
4760 The code that dealt with SIGIO was crufty and confusing, e.g., it
4761 played tricks like "#undef SIGIO" but these tricks were not used
4762 consistently. Simplify mostly by not #undeffing standard symbols,
4763 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4764 or not as we please) rather than "defined SIGIO" (standard symbol
4765 that we probably shouldn't #undef).
4766 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4767 Modules that need it can include it.
4768 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4769 * dispextern.h (ignore_sigio): New decl.
4770 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4771 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4772 * emacs.c (shut_down_emacs):
4773 * keyboard.c (kbd_buffer_store_event_hold):
4774 Use ignore_sigio rather than invoking 'signal' directly.
4775 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4776 for FIONREAD.
4777 (FIONREAD, SIGIO): Do not #undef.
4778 (tty_read_avail_input): Use #error rather than a syntax error.
4779 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4780 for I_PIPE, used by SETUP_SLAVE_PTY.
4781 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4782 * sysdep.c (croak): Remove; no longer needed. This bit of
4783 temporary code, with Fred N. Fish's comment that it's temporary,
4784 has been in Emacs since at least 1992!
4785 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4786 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4787 * syssignal.h (croak): Remove decl.
4788 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4789 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4790 now that we're termios-only.
4791 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4792 * term.c (dissociate_if_controlling_tty): Use #error rather than
4793 a run-time error.
4794
4795 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4796 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4797 to work around GNOME bug 683906.
4798 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4799 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4800 This works around GCC bug 54561.
4801
4802 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4803
4804 More fixes for 'volatile' and setjmp/longjmp.
4805 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4806 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4807 (png_load_body) [HAVE_PNG]:
4808 (jpeg_load_body) [HAVE_JPEG]:
4809 New function, with most of the old parent function's body.
4810 (png_load) [HAVE_PNG]:
4811 (jpeg_load) [HAVE_JPEG]:
4812 Invoke the new function, to avoid longjmp munging our locals.
4813 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4814 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4815 longjmp is passed 2, as the C standard doesn't guarantee this.
4816 Instead, store the failure code into mgr->failure_code.
4817
4818 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4819
4820 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4821 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4822 (syms_of_keyboard): Remove support for unread-command-char.
4823
4824 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4825
4826 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4827 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4828 violation. (Bug#12426)
4829
4830 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4831
4832 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4833
4834 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4835
4836 * eval.c: Add `inhibit-debugger'.
4837 (Qinhibit_debugger): New symbol.
4838 (call_debugger): Bind it instead of Qdebug_on_error.
4839 (maybe_call_debugger): Test Vinhibit_debugger.
4840 (syms_of_eval): Define inhibit-debugger.
4841 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4842 (syms_of_xdisp): Remove inhibit-debug-on-message.
4843
4844 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4845
4846 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4847 If a nonvolatile local variable is written before a _longjmp to
4848 the frame containing the variable, and is read after the _longjmp,
4849 the value read is indeterminate. Some local variables of type
4850 'struct handler' and 'struct catchtag' are used in this way, so
4851 mark each of their slots as volatile if the slot can be set before
4852 _longjmp and read afterwards.
4853 * lisp.h (struct handler): var and chosen_clause are now volatile.
4854 (struct catchtag): val, next, and pdlcount are now volatile.
4855
4856 * bidi.c (bidi_push_it, bidi_pop_it):
4857 * fns.c (copy_hash_table):
4858 * image.c (define_image_type):
4859 * keyboard.c (kbd_buffer_store_event_hold):
4860 * process.c (Fprocess_send_eof):
4861 * xfaces.c (x_create_gc) [HAVE_NS]:
4862 * xgselect.c (xg_select):
4863 Prefer assignment to memcpy when either will do.
4864
4865 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4866 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4867 time an item is removed. No need to mark this function 'inline';
4868 the compiler knows better than we do.
4869
4870 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4871
4872 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4873 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4874 to change_frame_size (Bug#12388).
4875 (windowDidResize:): Pass YES to updateFrameSize.
4876
4877 * nsterm.h: Add delay parameter to updateFrameSize.
4878
4879 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4880
4881 Discard killed buffers from deleted window and frame objects.
4882 This reduces an amount of references to killed buffers and
4883 helps GC to reclaim them faster.
4884 * alloc.c (discard_killed_buffers): New function.
4885 (mark_object): Use it for deleted windows and frames.
4886 (mark_object): If symbol's value is set up for a killed buffer
4887 or deleted frame, restore its global binding.
4888 * data.c (swap_in_global_binding): Add GC notice.
4889 (swap_in_symval_forwarding): Use convenient set_blv_where.
4890 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4891 * window.h: ... to here.
4892
4893 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4894
4895 Convenient macro to check whether the buffer is live.
4896 * buffer.h (BUFFER_LIVE_P): New macro.
4897 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4898 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4899
4900 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4901
4902 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4903 composition cases (Bug#12364).
4904
4905 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4906 overhang of succeeding glyphs overlapping box cursor.
4907
4908 * w32term.c (x_draw_glyph_string): Likewise.
4909
4910 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4911
4912 Simplify, document, and port floating-point (Bug#12381).
4913 The porting part of this patch fixes bugs on non-IEEE platforms
4914 with frexp, ldexp, logb.
4915 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4916 Now static.
4917 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4918 support, by removing commented-out code and briefly listing the
4919 C89 functions excluded. The commented-out stuff was confusing
4920 maintenance, e.g., we thought we needed cbrt but it was commented out.
4921 (logb): Remove decl; no longer needed.
4922 (isfinite): New macro, if not already supplied.
4923 (isnan): Don't replace any existing macro.
4924 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4925 are present on all C89 platforms.
4926 (Ffrexp): Do not special-case zero, as frexp does the right thing
4927 for that case.
4928 (Flogb): Do not use logb, as it doesn't have the desired meaning
4929 on hosts that use non-base-2 floating point. Instead, stick with
4930 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4931 frexp, to avoid getting an unspecified result.
4932
4933 * xdisp.c (Qinhibit_debug_on_message): Now static.
4934
4935 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4936
4937 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4938 NSBezierPath (Bug#12131).
4939
4940 2012-09-10 Chong Yidong <cyd@gnu.org>
4941
4942 * fns.c (Fdelq, Fdelete): Doc fix.
4943
4944 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4945
4946 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4947 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4948
4949 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4950
4951 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4952 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4953 Use it.
4954
4955 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4956
4957 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4958 left fringe if the window has a left margin. This avoids leaving
4959 traces of the cursor because its leftmost pixel is not drawn over.
4960
4961 * dispnew.c (update_window_line): When the left margin area of a
4962 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4963 that screen line. (Bug#12277)

4965 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4966
4967 Assume C89 or later for math functions (Bug#12381).
4968 This simplifies the code, and makes it a bit smaller and faster,
4969 and (most important) makes it easier to clean up signal handling
4970 since we can stop worring about floating-point exceptions in
4971 library code. That was a problem before C89, but the problem
4972 went away many years ago on all practical Emacs targets.
4973 * data.c, image.c, lread.c, print.c:
4974 Don't include <math.h>; no longer needed.
4975 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4976 might be autoconfigured, as that never happens.
4977 * data.c (fmod):
4978 * doprnt.c (DBL_MAX_10_EXP):
4979 * print.c (DBL_DIG):
4980 Remove. C89 or later always defines these.
4981 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4982 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4983 (arith_error, domain_error, domain_error2):
4984 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4985 no longer needed -- we simply return what C returns. All uses removed.
4986 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4987 the wrapped code.
4988 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4989 Remove. All uses expanded, as these macros are no longer used
4990 more than once and are now more trouble than they're worth.
4991 (Ftan): Use tan, not sin / cos.
4992 (Flogb): Assume C89 frexp.
4993 (fmod_float): Assume C89 fmod.
4994 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4995 (init_floatfns): Remove. All uses removed.

4998
4999 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5000 compositeToPoint for OSX < 10.6 (Bug#12390).
5001
5002 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5003
5004 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5005 This produces more-accurate results.
5006
5007 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5008
5009 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5010 changes (Bug#12088).

5016 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5017
5018 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5019 in the internal border.
5020 (x_set_window_size): Remove static variables and their usage.
5021 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5022 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5023 Remove fringe/internal border adjustment (Bug#11052).
5024 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5025 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5026 (ns_fix_rect_ibw): Remove.
5027 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5028 (ns_dumpglyphs_box_or_relief): Ditto.
5029 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5030 adjustment.
5031 (ns_dumpglyphs_image): Ditto.
5032 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5033 border adjustment.
5034 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5035 their usage. Add fringe_extended_p and its use as in other terms.
5036 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5037 scroll bar was removed.
5038 (updateFrameSize): New function.
5039 (windowDidResize): Move code to updateFrameSize and call it.
5040
5041 * nsterm.h (EmacsView): Add updateFrameSize.
5042
5043 2012-09-07 Chong Yidong <cyd@gnu.org>

5050
5051 More signal-handler cleanup (Bug#12327).
5052 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5053 Problem introduced when merging patches. Noted by Eli Zaretskii in
5054 <http://bugs.gnu.org/12327#67>.
5055 * floatfns.c: Comment fix.
5056 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5057 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5058 and anyway the declaration is harmless even if SIGDANGER is not defined.
5059 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5060 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5061 source files not surprisingly expected syssignal.h to define, or
5062 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5063 Include <sys/ioctl.h>, for FIONREAD.
5064 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5065 This eliminates a problem whereby other files mysteriously had
5066 to include "syssignal.h" before including "systty.h" if they
5067 wanted to use "#ifdef SIGIO".
5068
5069 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5070
5071 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5072
5073 * w32.c (sigemptyset): Empty the set.
5074 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5075
5076 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5077
5078 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5079
5080 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5081 (mark_object): Likewise for frame objects.
5082
5083 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5084
5085 * syssignal.h (handle_on_main_thread): Always declare,
5086 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5087 This ports to platforms without HAVE_PTHREAD.
5088
5089 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>

5091 Signal-handler cleanup (Bug#12327).
5092 Emacs's signal handlers were written in the old 4.2BSD style with
5093 sigblock and sigmask and so forth, and this led to some
5094 inefficiencies and confusion. Rewrite these to use
5095 pthread_sigmask etc. without copying signal sets around. Also,
5096 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5097 'signal', and instead use functions that do not attempt to take
5098 over the system name space. This patch causes Emacs's text
5099 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5100 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5101 Do not include <signal.h> or "syssignal.h", as these
5102 modules do not use signals.
5103 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5104 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5105 Do not include <signal.h>, as "syssignal.h" does that for us now.
5106 * atimer.c (sigmask_atimers): New function.
5107 (block_atimers, unblock_atimers): New functions,
5108 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5109 All uses replaced.
5110 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5111 no longer needed here.
5112 * emacs.c (main): Inspect existing signal handler with sigaction,
5113 so that there's no need to block and unblock SIGHUP.
5114 * sysdep.c (struct save_signal): New member 'action', replacing
5115 old member 'handler'.
5116 (save_signal_handlers, restore_signal_handlers):
5117 Use sigaction instead of 'signal' to save and restore.
5118 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5119 New function. All users of 'signal' modified to use set_sighandler
5120 if they're writeonly, and to use sys_signal if they're read+write.
5121 (emacs_sigaction_init, forwarded_signal): New functions.
5122 (sys_signal): Remove. All uses replaced by calls to sigaction
5123 and emacs_sigaction_init, or by direct calls to 'signal'.
5124 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5125 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5126 all uses replaced by pthread_sigmask etc. calls.
5127 * syssignal.h: Include <signal.h>.
5128 (emacs_sigaction_init, forwarded_signal): New decls.
5129 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5130 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5131 (sigmask, sys_sigmask): Remove; no longer needed.
5132 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5133 (sigblock, sigunblock, sigfree):
5134 (sigsetmask) [!defined sigsetmask]:
5135 Remove. All uses replaced by pthread_sigmask.
5136 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5137 no longer need to be replaced, and its typical old uses
5138 are now done via emacs_sigaction_init and sigaction.
5139 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5140 (sys_sigdel): Remove; unused.
5141 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5142
5143 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5144
5145 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5146 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5147
5148 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5149
5150 Explicitly mark buffer_defaults and buffer_local_symbols.
5151 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5152 mark_local_symbols here.
5153 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5154 since special buffers aren't marked here any more.
5155 (allocate_buffer): Chain new buffer with all_buffers here...
5156 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5157 not here.
5158 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5159 (syms_of_buffer): Remove staticpro of the above.
5160 (init_buffer_once): Set names for buffer_defaults and
5161 buffer_local_symbols.
5162
5163 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>

5167 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5168 (generate_otf_features, font_check_otf_features, font_check_otf)
5169 (font_match_p, font_list_entities, font_at):

5171 (fontset_find_font, Fset_fontset_font)
5172 (face_suitable_for_char_p) [0]:
5173 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5174 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5175 (m17n_flt_initialized, ftfont_shape_by_flt):
5176 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5177 * nsfont.m (nsfont_draw):
5178 * w32font.c (w32font_draw):
5179 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5180 Use bool for booleans.
5181 * font.h: Adjust to above API changes.
5182 (struct font, struct font_driver, struct font_driver_list):
5183 Use bool for booleans.
5184 (struct font): Remove useless member encoding_type.
5185 All users removed.
5186 * fontset.c, xftfont.c: Omit unnecessary static decls.
5187
5188 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5189
5190 * alloc.c (mark_object): Revert window marking code
5191 since it's unsafe for the Fset_window_configuration.
5192
5193 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5194
5195 Fix race conditions with signal handlers and errno (Bug#12327).
5196 Be more systematic about preserving errno whenever a signal
5197 handler returns, even if it's not in the main thread. Do this by
5198 renaming signal handlers to distinguish between signal delivery
5199 and signal handling. All uses changed.
5200 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5201 * data.c (deliver_arith_signal): Rename from arith_error.
5202 * dispnew.c (deliver_window_change_signal): Rename from
5203 window_change_signal.
5204 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5205 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5206 * keyboard.c (deliver_input_available_signal): Rename from
5207 input_available_signal.
5208 (deliver_user_signal): Rename from handle_user_signal.
5209 (deliver_interrupt_signal): Rename from interrupt_signal.
5210 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5211 (deliver_child_signal): Rename from sigchld_handler.
5212 * atimer.c (handle_alarm_signal):
5213 * data.c (handle_arith_signal):
5214 * dispnew.c (handle_window_change_signal):
5215 * emacs.c (handle_fatal_signal, handle_danger_signal):
5216 * keyboard.c (handle_input_available_signal):
5217 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5218 * process.c (handle_pipe_signal, handle_child_signal):
5219 New functions, with the actual signal-handling code taken from the
5220 original respective signal handlers, sans the sporadic attempts to
5221 preserve errno, since that's now done by handle_on_main_thread.
5222 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5223 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5224 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5225 Move to sysdep.c.
5226 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5227 Move initialization of main_thread to sysdep.c's init_signals.
5228 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5229 our usage, and simplifies the mainline code.
5230 (record_child_status_change): New static function, as a helper
5231 for handle_child_signal, and with most of the old child handler's
5232 contents.
5233 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5234 (handle_child_signal): Use the above.
5235 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5236 Moved here from emacs.c.
5237 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5238 code moved here from emacs.c's main function.
5239 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5240 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5241 This lets callers save and restore errno properly.
5242
5243 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5244
5245 Remove redundant or unused things here and there.
5246 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5247 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5248 * editfns.c (Fcompare_buffer_substrings): Likewise.
5249 * frame.h (struct terminal, struct font_driver_list):
5250 Remove redundant declarations.
5251 * window.h (Qleft, Qright): Likewise.
5252
5253 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5254
5255 Do not mark objects from deleted buffers, windows and frames.
5256 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5257 (mark_object): Likewise for windows and frames.
5258
5259 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5260
5261 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5262 buffer_defaults and buffer_local_symbols as valid objects.
5263 Return special value to denote them.
5264
5265 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5266
5267 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5268 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5269 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5270 (file_name_absolute_p, Fsubstitute_in_file_name):
5271 (check_executable, check_writable, Ffile_accessible_directory_p)

5273 (Finsert_file_contents, choose_write_coding_system)
5274 (Fwrite_region, build_annotations, a_write, e_write)
5275 (Fdo_auto_save):
5276 * filelock.c (boot_time_initialized, get_boot_time)
5277 (get_boot_time_1, lock_file_1, within_one_second):
5278 * floatfns.c (in_float):
5279 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5280 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5281 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5282 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5283 * window.c (compare_window_configurations):
5284 Use bool for booleans.
5285 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5286 (Fdefault_file_modes): Now mode_t, not int, for modes.
5287 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5288 (internal_delete_file): Now returns void, not a (boolean) int,
5289 since nobody was looking at the return value.
5290 * lisp.h, window.h: Adjust to above API changes.
5291
5292 * xdisp.c (set_message): Simplify and reindent last change.
5293
5294 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5295
5296 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5297
5298 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5299
5300 * eval.c (call_debugger): Make the function non-static so that we
5301 can call it from set_message.
5302
5303 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5304 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5305
5306 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5307
5308 Give more-useful info on a fatal error (Bug#12328).
5309 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5310 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5311 of doing the work ourselves.
5312 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5313 do most of the work.
5314 (fatal_error_backtrace): New function, taken from the guts
5315 of the old fatal_error_signal, but with a new option to output
5316 a backtrace.
5317 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5318 info about the signal than just its number.
5319 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5320 * sysdep.c: Include <execinfo.h>
5321 (emacs_backtrace): New function, taken partly from the previous
5322 code of the 'die' function.
5323 (emacs_abort): Call fatal_error_backtrace rather than abort.
5324
5325 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5326
5327 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5328 eager (load-time) macro-expansion.
5329 * lisp.mk (lisp): Add macroexp.
5330
5331 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5332
5333 Simplify redefinition of 'abort' (Bug#12316).
5334 Do not try to redefine the 'abort' function. Instead, redo
5335 the code so that it calls 'emacs_abort' rather than 'abort'.
5336 This removes the need for the NO_ABORT configure-time macro
5337 and makes it easier to change the abort code to do a backtrace.
5338 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5339 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5340 Remove; sysdep.c's emacs_abort now takes its place.
5341 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5342 'abort' changed to use 'emacs_abort'.
5343 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5344 (abort) [!defined abort]: Rename to ...
5345 (emacs_abort): ... new name.
5346 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5347 the place of the old 'abort' in emacs.c.
5348 * w32.c, w32fns.c (abort): Do not #undef.
5349 * w32.c (emacs_abort): Rename from w32_abort.
5350
5351 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5352
5353 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5354 offsets[j].dv, since the y axis of the screen coordinates points
5355 down, while the y axis of the font definition coordinates points
5356 up. This fixes display of Arabic diacritics such as KASRA and
5357 KASRATAN. (Bug#11860)

5359 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5360
5361 Be more systematic about _setjmp vs setjmp.
5362 * alloc.c (test_setjmp, mark_stack):
5363 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5364 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5365 (png_load, my_error_exit, jpeg_load):
5366 * process.c (send_process_trap, send_process):
5367 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5368 The underscored versions are up to 30x faster on some hosts.
5369 Formerly, the code used setjmp+longjmp sometimes and
5370 _setjmp+_longjmp at other times, with no particular reason to
5371 prefer setjmp+longjmp.
5372
5373 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5374
5375 Fix minor problem found by static checking.

5403 * dispextern.h, lisp.h: Reflect above API changes.
5404 * firstfile.c (dummy): Use the address of 'main', whose signature
5405 won't change, instead of the address of 'initialize', whose
5406 signature just changed from int to bool.
5407 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5408 * msdos.c (fatal_error_in_progress): ... from here.
5409 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5410 of incrementing it.
5411 (redisplay_internal, unwind_redisplay): Simply clear
5412 REDISPLAYING_P when unwinding, instead of saving its previous,
5413 always-false value and then restoring it.
5414
5415 Clean up some extern decls.
5416 Mostly, this hoists extern decls out of .c files and into .h files.
5417 That way, we're more likely to catch errors if the interfaces change.
5418 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5419 declare xg_mark_data.
5420 * dispextern.h (x_frame_parm_handlers):

5440 Remove now-redundant extern decls.
5441 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5442 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5443 Now static.
5444 * xfaces.c: Remove unnecessary static decls.
5445 * xterm.c (updating_frame): Remove decl of nonexistent object.
5446
5447 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5448 when building globals.h, as the objects that are not built on
5449 this host are not needed to compile C files on this host.
5450

5452
5453 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5482 Use bool for boolean.
5483 * intervals.h, lisp.h, systime.h: Reflect above API changes.

5492
5493 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

5500
5501 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5502
5503 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5504 more than one grapheme cluster passed to the shaper: compute the
5505 offset adjustment values separately for each cluster. (Bug#11860)
5506
5507 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5508 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5509 about implicit conversions from integer to pointer.
5510
5511 2012-09-01 Daniel Colascione <dancol@dancol.org>
5512
5513 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

5535 * xfaces.c: Include TERM_HEADER instead of listing all possible
5536 window-system headers.
5537
5538 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
5539 to match header.
5540

5599 * lisp.h (mark_ttys): Remove prototype.
5600 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

5632
5633 * lread.c (init_lread): For out-of-tree builds, only add the
5634 source directory's site-lisp dir to the load-path if it exists,
5635 consistent with in-tree builds. (Bug#12302)
5636
5637 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5638
5639 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

5734 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
5735 * dired.c (file_name_completion):
5736 Use bool for boolean. (This was missed in an earlier change.)
5737
5738 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5739

5749 (windowShouldClose:): Use stop instead of stopModalWithCode.
5750 (clicked:): Ditto, and also set dialog_return (Bug#12258).
5751 (timeout_handler:): Use stop instead of abortModal. Send a dummy
5752 event.
5753 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
5754 modal loop returns.
5755
5756 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
5757
5758 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
5759 * composite.c (find_composition, composition_gstring_p)
5760 (composition_reseat_it, find_automatic_composition):
5761 * data.c (let_shadows_buffer_binding_p)
5762 (let_shadows_global_binding_p, set_internal, make_blv)
5763 (Fmake_variable_buffer_local, Fmake_local_variable)
5764 (Fmake_variable_frame_local, arithcompare, cons_to_unsigned)
5765 (cons_to_signed, arith_driver):
5766 * dbusbind.c (xd_in_read_queued_messages):
5767 * dired.c (directory_files_internal, file_name_completion):
5768 Use bool for booleans.
5769 * dired.c (file_name_completion):
5770 * process.h (fd_callback):
5771 Omit int (actually boolean) argument. It wasn't being used.
5772 All uses changed.
5773 * composite.h, lisp.h: Reflect above API changes.
5774
5775 * cmds.c, coding.c: Use bool for booleans.
5776 * cmds.c (move_point, Fself_insert_command):
5777 * coding.h (struct composition status, struct coding_system):
5778 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
5779 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)
5780 (emacs_mule_char, decode_coding_emacs_mule)
5781 (encode_coding_emacs_mule, detect_coding_iso_2022)
5782 (decode_coding_iso_2022, encode_invocation_designation)
5783 (encode_designation_at_bol, encode_coding_iso_2022)
5784 (detect_coding_sjis, detect_coding_big5, decode_coding_sjis)
5785 (decode_coding_big5, encode_coding_sjis, encode_coding_big5)
5786 (detect_coding_ccl, encode_coding_ccl, decode_coding_raw_text)
5787 (encode_coding_raw_text, detect_coding_charset)
5788 (decode_coding_charset, encode_coding_charset, detect_eol)
5789 (detect_coding, get_translation_table, produce_chars)
5790 (consume_chars, reused_workbuf_in_use)

5795 (code_convert_string, code_convert_string_norecord)
5796 (Fset_coding_system_priority):
5797 * fileio.c (Finsert_file_contents):
5798 Use bool for booleans.
5799 * coding.h, lisp.h: Reflect above API changes.
5800 * coding.c: Remove unnecessary static function decls.
5801 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5802 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5803 not a boolean 'int', since callers never look at the return value.
5804 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5805 * coding.h (decoding_buffer_size, encoding_buffer_size)
5806 (emacs_mule_string_char): Remove unused extern decls.
5807 (struct iso_2022_spec, struct coding_system):
5808 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5809 (struct emacs_mule_spec): Remove unused field 'full_support'.
5810 All initializations removed.
5811 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5812
5813 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5814
5815 Fix spare memory change (Bug#12286).
5816 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5817 (valid_lisp_object_p): Likewise.
5818
5819 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5820
5821 * window.c (Fset_window_configuration): Record any window's old
5822 buffer if it's replaced (see Bug#8789). If the new current
5823 buffer doesn't appear in the selected window, go to its old
5824 point (Bug#12208).
5825
5826 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5827
5828 Special MEM_TYPE_SPARE to denote reserved memory.
5829 * alloc.c (enum mem_type): New memory type.
5830 (refill_memory_reserve): Use new type for spare memory.
5831 This prevents live_cons_p and live_string_p from incorrect
5832 detection of uninitialized objects from spare memory as live.
5833
5834 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5835
5836 Spelling fixes.
5837 * Makefile.in (.PHONY): versioclean -> versionclean.
5838
5839 Remove unused external symbols.
5840 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5841 * window.c (Qwindow_valid_p, decode_valid_window):
5842 Now static, not extern.
5843 * data.c (Qinterval): Remove; unused.
5844 (syms_of_data): Do not define 'interval'.
5845 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5846 * window.h (decode_valid_window):
5847 Remove decls.
5848
5849 * character.c, charset.c, chartab.c: Use bool for booleans.
5850 * character.c (lisp_string_width, string_count_byte8)
5851 (string_escape_byte8):
5852 * charset.c (charset_map_loaded, load_charset_map, read_hex):
5853 (load_charset_map_from_file, map_charset_chars)
5854 (Fdefine_charset_internal, define_charset_internal)
5855 (Fdeclare_equiv_charset, find_charsets_in_text)
5856 (Ffind_charset_region, char_charset, Fiso_charset):
5857 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
5858 (sub_char_table_set, sub_char_table_set_range)
5859 (char_table_set_range, optimize_sub_char_table)
5860 (map_sub_char_table):
5861 Use bool for boolean.
5862 * character.c (str_to_unibyte): Omit last boolean argument; it was
5863 always 0. All callers changed.
5864 * character.h, charset.h: Adjust to match previous changes.
5865 * character.h (char_printable_p): Remove decl of nonexistent function.
5866 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5867 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5868 are all boolean, so make them single-bit bitfields.
5869
5870 * lisp.h (ASET): Remove attempt to detect side effects.
5871 It was meant to be temporary and it often doesn't work,
5872 because when IDX has side effects the behavior of IDX==IDX
5873 is undefined. See Stefan Monnier in
5874 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5875
5876 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5877
5878 * lisp.h (functionp): New function (extracted from Ffunctionp).
5879 (FUNCTIONP): Use it.
5880 * eval.c (Ffunctionp): Use it.
5881
5882 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5883
5884 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5885 as that's faster and simpler than static storage. Don't bother
5886 with the g_main_context_query overhead if g_main_context_pending
5887 says no events are pending.
5888 (gfds, gfds_size): Remove these static vars.
5889 (xgselect_initialize): Remove; no longer needed.
5890 All uses and decls removed.
5891
5892 * emacs.c (fatal_error_signal_hook): Remove.
5893 All uses removed. This leftover from old code was always 0.
5894
5895 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5896 * casefiddle.c (casify_object, casify_region):
5897 * casetab.c (set_case_table):
5898 * category.c, category.h (word_boundary_p):
5899 * category.h (CHAR_HAS_CATEGORY):
5900 Use bool for booleans, instead of int.
5901
5902 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5903
5904 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5905
5906 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5907
5908 On assertion failure, print backtrace if available.
5909 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5910 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5911 * Makefile.in (LIB_EXECINFO): New macro.
5912 (LIBES): Use it.
5913
5914 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5915 * bytecode.c (exec_byte_code):
5916 * callint.c (check_mark, Fcall_interactively):
5917 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5918 (getenv_internal, sync_process_alive, call_process_exited):
5919 * lisp.h (USE_SAFE_ALLOCA):
5920 Use bool for booleans, instead of int.
5921 * lisp.h, process.h: Adjust prototypes to match above changes.
5922 * callint.c (Fcall_interactively): Don't assume the mark's
5923 offset fits in 'int'.
5924
5925 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5926
5927 * buffer.c, buffer.h: Use bool for boolean.
5928 * buffer.c (reset_buffer_local_variables)
5929 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5930 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
5931 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
5932 (overlay_touches_p, overlay_strings, Foverlay_put)
5933 (report_overlay_modification, call_overlay_mod_hooks):
5934 (mmap_enlarge, mmap_set_vars):
5935 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5936 Use bool for booleans, instead of int.
5937 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5938 since the 1-or-0 return value is always ignored anyway.
5939 (mmap_initialized_p):
5940 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5941 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5942
5943 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5944
5945 * bidi.c: Use bool for boolean.
5946 This is a bit more readable, and makes the text segment of bidi.o
5947 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5948 Presumably it's faster too.
5949 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5950 Now bool.
5951 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5952 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5953 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5954 (bidi_explicit_dir_char, bidi_level_of_next_char)
5955 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5956 Use bool for booleans, instead of int.
5957 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5958 (bidi_unshelve_cache): Adjust decls to match code.
5959
5960 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5961
5962 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5963 argument.
5964
5965 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5966
5967 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5968 * atimer.h: Include <stdbool.h>.
5969
5970 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5971
5972 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5973 compile time tests instead of run time tests on systems that do
5974 not use them.
5975 (FRAME_MAC_P): Remove leftover from deleted code.
5976 * frame.c (syms_of_frame): Remove leftover from deleted code.
5977
5978 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5979
5980 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5981
5982 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5983
5984 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5985 Otherwise, the compiler complains about (A?B:C) where B is void
5986 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5987 (fontset_add): Return void, for FONTSET_ADD.
5988
5989 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5990
5991 * alloc.c: Use bool for booleans.
5992 (gc_in_progress, abort_on_gc)
5993 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5994 (dont_register_blocks) [GC_MALLOC_CHECK]:
5995 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5996 (check_string_bytes, make_specified_string, memory_full)
5997 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5998 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5999 (mark_stack, valid_pointer_p, make_pure_string)
6000 (Fgarbage_collect, survives_gc_p, gc_sweep):
6001 Use bool for booleans, instead of int.
6002 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6003 Remove unused local.
6004 * alloc.c (PURE_POINTER_P):
6005 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6006 * editfns.c (Fformat):
6007 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6008 (Fdo_auto_save):
6009 * fns.c (sweep_weak_table):
6010 * lisp.h (suppress_checking, push_message, survives_gc_p)
6011 (make_pure_string, gc_in_progress, abort_on_gc):
6012 * lread.c (readchar, read1):
6013 * print.c (Fprin1_to_string):
6014 * xdisp.c (push_message):
6015 Use bool for booleans affected directly or indirectly by
6016 alloc.c's changes.
6017
6018 Make recently-introduced setters macros.
6019 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6020 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6021 (set_fontset_default, set_fontset_fallback): Rename from their
6022 upper-case counterparts, and make them functions rather than macros.
6023 This is more consistent with the other recently-introduced setters.
6024 These don't need to be inline, since they're local.
6025
6026 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6027
6028 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6029 the loop (Bug#12247).
6030
6031 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6032
6033 * lisp.h (vcopy): Use memcpy rather than our own loop.
6034 This fixes a performance regression introduced by the recent
6035 addition of vcopy. This means 'vcopy' will need to be modified
6036 for a copying collector, but that's OK. Also, tighten the
6037 checking in the assertion.
6038
6039 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6040
6041 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6042 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6043 non-base glyph for the width of the base character, according to
6044 what x_draw_composite_glyph_string_foreground expects.
6045 Generate WADJUST value according to composition_gstring_width's
6046 expectations, to produce correct width of the composed character.
6047 Reverse the sign of the DU offset produced by ScriptPlace.
6048
6049 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6050
6051 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6052
6053 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6054
6055 Avoid direct writes to contents member of struct Lisp_Vector.
6056 * lisp.h (vcopy): New function to copy data into vector.
6057 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6058 * fns.c (Ffillarray): Use ASET.
6059 * keyboard.c (timer_check_2): Use AREF and ASET.
6060 (append_tool_bar_item, Frecent_keys): Use vcopy.
6061 * lread.c (read_vector): Use ASET.
6062 * msdos.c (Frecent_doskeys): Use vcopy.
6063 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6064 (Finternal_merge_in_global_face): Use ASET and vcopy.
6065 * xfont.c (xfont_list_pattern): Likewise.
6066
6067 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6068
6069 * window.c (Fwindow_point): For the selected window always return
6070 the position of its buffer's point.
6071 (Fset_window_point): For the selected window always go in its
6072 buffer to the specified position.
6073
6074 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6075
6076 Setter macros for fontsets.
6077 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6078 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6079 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6080 Adjust users.
6081
6082 2012-08-20 Glenn Morris <rgm@gnu.org>
6083
6084 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6085 Don't assume that `ln -f' works.
6086
6087 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6088
6089 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6090 and later about non-assignments with no effect. See discussion at
6091 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6092 details.
6093
6094 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6095
6096 Inline setter functions for Lisp_Objects slots of struct specbinding.
6097 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6098 Adjust users.
6099
6100 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6101
6102 * window.c (select_window): Always make selected window's buffer
6103 current.
6104
6105 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6106
6107 Use AREF and ASET for docstrings of category tables.
6108 * category.h (CATEGORY_DOCSTRING): Use AREF.
6109 (SET_CATEGORY_DOCSTRING): Use ASET.
6110 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6111
6112 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6113
6114 Inline setter functions for hash table members.
6115 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6116 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6117 (set_hash_key_and_value, set_hash_index, set_hash_next)
6118 (set_hash_hash): New functions.
6119 * charset.c, fns.c: Adjust users.
6120
6121 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6122
6123 Inline getter and setter functions for per-buffer values.
6124 * buffer.h (per_buffer_default, set_per_buffer_default)
6125 (per_buffer_value, set_per_buffer_value): New functions.
6126 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6127 * buffer.c, data.c: Adjust users.
6128
6129 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6130
6131 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6132
6133 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6134
6135 Rely on <config.h> + <unistd.h> to declare 'environ',
6136 as gnulib does this if the system doesn't.
6137 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6138 Remove declaration. MS-Windows declares it on stdlib.h which is
6139 included by conf_post.h.
6140 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6141 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6142 * vm-limit.c: Include <unistd.h>, for 'environ'.
6143
6144 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6145 (start_of_data): Remove decl; mem-limits.h provides it.
6146
6147 * xdisp.c (handle_invisible_prop): Make it a bit faster

6173 Return void, not Lisp_Object. Otherwise, the compiler

6175 when compiling CHAR_TABLE_SET, due to the recent change to
6176 the API of sub_char_table_set_contents.

6949
6950 Fix replacement typo.
6951 * window.c (replace_window): Set root_window instead of

7009 * w32.c (init_environment): Change the default values of many
7010 environment variables in dflt_envvars[] to NULL, to avoid pushing
7011 them into environment when they were not already defined.
7012 Remove the code that deletes site-lisp subdirectories from the default
7013 value of EMACSLOADPATH, as it is no longer needed.
7014 (check_windows_init_file): Now external, not static.
7015 Use Vload_path as is, without adding anything, as this function is now
7016 called when Vload_path is already set up.
7017
7018 * w32.h (check_windows_init_file): Add prototype.
7019
7020 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
7021 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
7022 compatibility with Posix platforms.
7023 (main): Move the call to check_windows_init_file to here from
7024 w32.c.
7025 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
7026 any, in the DEFALT argument into the root of the Emacs build or
7027 installation tree, as appropriate.
7028
7029 * callproc.c (init_callproc_1): Call decode_env_path instead of
7030 doing its equivalent by hand.

7032 the code that sets Vexec_path run on MS-Windows.
7033
7034 * lread.c (init_lread): Add comments to #ifdef's.
7035
7036 * msdos.c (dos_set_window_size, IT_update_begin)
7037 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
7038 instead of direct references.

7045
7046 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
7047
7048 Remove unnecessary casts involving pointers.
7049 These casts are no longer needed now that we assume C89 or later,
7050 since they involve casting to or from void *.
7051 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
7052 (make_pure_float, make_pure_vector):
7053 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

7061 * xselect.c (x_stop_queuing_selection_requests)
7062 (x_get_window_property, x_get_window_property_as_lisp_data):
7063 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7064 Remove unnecessary pointer casts.
7065 * alloc.c (record_xmalloc): New function.
7066 * lisp.h (record_xmalloc): New decl.
7067 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7068 more like a function. This is because the pointer cast is not
7069 needed. All uses changed.
7070 * print.c (print_string, print_error_message): Avoid length recalc.
7071
7072 Improve fix for macroexp crash with debugging (Bug#12118).
7073 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7074 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7075 not supposed to be invoked from the garbage collector.
7076 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7077 (gc_aset): New function, which is like ASET but can be
7078 used in the garbage collector.
7079 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
7080 (set_hash_index): Use it instead of ASET.

7096 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
7097 New functions.
7098 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
7099 in the argument file name.
7100 (sys_access): Call unc_volume_file_attributes only if
7101 GetFileAttributes fails with network-related error codes.
7102 (sys_rename): Diagnose renaming of a symlink when the user doesn't
7103 have the required privileges.
7104 (get_file_security_desc_by_name): Rename from
7105 get_file_security_desc.

7107 with addition of handling of symlinks and support for 'lstat'.
7108 If possible, get file's attributes and security information by
7109 handle, not by name. Produce S_IFLNK bit for symlinks, when
7110 called from 'lstat'.
7111 (stat, lstat): New functions, call 'stat_worker'.
7112 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7113 symlinks when the underlying filesystem supports them.
7114
7115 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7116
7117 Fix macroexp crash on Windows with debugging (Bug#12118).
7118 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7119 checking subscripts; problem introduced with the recent
7120 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7121 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7122 since it's used in non-static inline functions now.
7123
7124 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7125 Don't assume buffer size fits in 'int'. Remove unused local.

7139 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
7140 * alloc.c (LISP_INLINE):
7141 * buffer.c (BUFFER_INLINE):
7142 * category.c (CATEGORY_INLINE):
7143 * character.c (CHARACTER_INLINE):
7144 * charset.c (CHARSET_INLINE):
7145 * composite.c (COMPOSITE_INLINE):
7146 * dispnew.c (DISPEXTERN_INLINE):
7147 * sysdep.c (SYSTIME_INLINE):
7148 Define to EXTERN_INLINE, so that the corresponding functions
7149 are compiled into code.

7151 (INLINE_HEADER_END): New macros.
7152 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7172 hard-coding the path separator.
7173
7174 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7175
7176 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7177 This how ASET and AREF are supposed to work, and makes
7178 it easier to think about future improvements. See
7179 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

7670 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from

7672 the fix for 12036 would have avoided some of the problems noted in
7673 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7674 would have been more obvious.

7684 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7685 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7686 not be usable in #if. This simplifies things.
7687
7688 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7689
7690 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7695 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =

7701 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7702 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7703 instead of gdb_valbits.
7704 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7705 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7706 instead of gdb_array_mark_flag.
7707 (xboolvector): Get size from $->size, not $->header.size.
7708 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7709 (xreload, hook-run, hookpost-run): Remove.
7710 * emacs.c: Include <verify.h>.
7711 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7712 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7713 Remove.
7714 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7715 (gdb_USE_LSB_TAG): New enum constants.
7716 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7717 Also define these as enum constants, so they're visible to GDB.

7719 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

7723 Now enum constants, not macros, so they're visible to GDB.
7724 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7725 more convenient now. All uses changed.
7726 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7727 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7728

7730
7731 Explicitly free restriction data that are not needed anymore.
7732 * editfns.c (save_restriction_restore): Free restriction data.
7733
7734 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
7735

8561 * s/aix4-2.h (unix): Remove; no longer needed.
8562
8563 EMACS_TIME simplification (Bug#11875).
8564 This replaces macros (which typically do not work in GDB)
8565 with functions, typedefs and enums, making the code easier to debug.
8566 The functional style also makes code easier to read and maintain.
8567 * systime.h: Include <sys/time.h> on all hosts, not just if
8568 WINDOWSNT, since 'struct timeval' is needed in general.
8569 (EMACS_TIME): Now a typedef, not a macro.
8570 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
8571 not macros.
8572 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
8573 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
8574 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
8575 (EMACS_TIME_LE): Now functions, not macros.
8576 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
8577 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
8578 which are not functions. All uses rewritten to use:
8579 (make_emacs_time): New function.
8580 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8581 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8582 not functions. All uses rewritten to use the following, respectively:
8583 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8584 (add_emacs_time, sub_emacs_time): New functions.
8585 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8586 * fileio.c (Fcopy_file):
8587 * xterm.c (XTflash): Get the current time closer to when it's used.
8588 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
8589
8590 * bytecode.c (targets): Suppress -Woverride-init warnings.

8595 * frame.c (Fmake_terminal_frame):
8596 * gtkutil.c (get_utf8_string):
8597 * lread.c (openp):
8598 * nsmenu.m (ns_update_menubar):
8599 * regex.c (regerror):
8600 Prefer memcpy to strncpy and strncat when either will do.
8601 * fileio.c (Fsubstitute_in_file_name):
8602 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8603 (menu_separator_name_p):
8604 * nsmenu.m (ns_update_menubar):
8605 Prefer memcmp to strncmp when either will do.
8606 * nsterm.m: Include <ftoastr.h>.
8607 (ns_get_color):
8608 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8609 Prefer snprintf to strncpy.
8610 * nsterm.m (ns_term_init):
8611 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8612 * nsterm.m (ns_term_init):
8613 Avoid the need for strncpy, by using build_string or
8614 make_unibyte_string directly. Use dtoastr, not snprintf.
8615 * process.c (Fmake_network_process): Diagnose service names that
8616 are too long, rather than silently truncating them or creating
8617 non-null-terminated names.
8618 (Fnetwork_interface_info): Likewise, for interface names.
8619 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8620 Prefer sprintf to strncat.
8621 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8622 Prefer vsnprintf to vsprintf + strncpy.
8623
8624 2012-07-10 Glenn Morris <rgm@gnu.org>
8625
8626 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8627 Clarify fallback case.
8628
8629 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8630
8631 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
8632 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
8633 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8634 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8635 where argument type is known to be a Lisp_Cons.
8636
8637 2012-07-10 Tom Tromey <tromey@redhat.com>
8638
8639 * bytecode.c (BYTE_CODE_THREADED): New macro.
8640 (BYTE_CODES): New macro. Replaces all old byte-code defines.
8641 (enum byte_code_op): New type.
8642 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

8644
8645 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8646
8647 Optimize pure C strings initialization.
8648 * lisp.h (make_pure_string): Fix prototype.
8649 (build_pure_c_string): New function, defined as static inline. This
8650 provides a better opportunity to optimize away calls to strlen when
8651 the function is called with compile-time constant argument.
8652 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8653 argument, adjust users accordingly. Use build_pure_c_string where
8654 appropriate.
8655 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8656 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8657 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8658
8659 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8660
8661 Avoid calls to strlen in miscellaneous functions.
8662 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8663 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8664 * lread.c (openp): Likewise.
8665
8666 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8667
8668 Avoid calls to strlen in path processing functions.
8669 * fileio.c (file_name_as_directory): Add comment. Change to add
8670 srclen argument and return the length of result. Adjust users
8671 accordingly.
8672 (directory_file_name): Fix comment. Change to add srclen argument,
8673 swap 1st and 2nd arguments to obey the common convention.
8674 Adjust users accordingly.
8675 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8676
8677 2012-07-10 Glenn Morris <rgm@gnu.org>
8678
8679 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
8680 Move PENDING_OUTPUT_COUNT definition to configure.
8681
8682 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
8683 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8684 * s/gnu.h (DATA_START): Move definitions to configure.
8685
8686 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8687 We include usg5-4-common.h, which defines them both.
8688
8689 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8690 O_RDONLY already includes it).
8691
8692 Stop ns builds setting the EMACSLOADPATH environment variable.
8693 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8694 Now it does not set EMACSLOADPATH, just returns the load-path string.
8695 * nsterm.h: Update accordingly.
8696 * lread.c [HAVE_NS]: Include nsterm.h.
8697 (init_lread) [HAVE_NS]: Use ns_load_path.
8698 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8699
8700 2012-07-09 Glenn Morris <rgm@gnu.org>
8701
8702 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8703 since the included bsd-common.h does so.
8704
8705 Stop ns builds setting the EMACSPATH environment variable.
8706 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8707 (ns_init_paths): Do not set EMACSPATH.
8708 * nsterm.h (ns_exec_path): Add it.

8713
8714 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8715
8716 * process.c (wait_reading_process_output): 'waitchannels' was unset
8717 when read_kbd || !NILP (wait_for_cell); fix this.
8718
8719 Add GCC-style 'const' attribute to functions that can use it.
8720 * character.h (char_resolve_modifier_mask):
8721 * keyboard.h (make_ctrl_char):
8722 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8723 (init_character_once, next_almost_prime, init_fns, init_image)
8724 (flush_pending_output, init_sound):
8725 * mem-limits.h (start_of_data):
8726 * menu.h (finish_menu_items):
8727 Add ATTRIBUTE_CONST.
8728 * emacs.c (DEFINE_DUMMY_FUNCTION):
8729 Declare the dummy function with ATTRIBUTE_CONST.
8730 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8731 Add decls with ATTRIBUTE_CONST.
8732
8733 Minor improvements to make_formatted_string.
8734 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8735 where int is good enough, as vsprintf returns an int.
8736 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8737
8738 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8739

8764
8765 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8766
8767 Move marker debugging code under MARKER_DEBUG.
8768 * marker.c (MARKER_DEBUG): Move marker debugging code under
8769 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8770 for bootstrap with --enable-checking (~3x slowdown reported
8771 by Juanma Barranquero <lekktu@gmail.com>).
8772 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8773
8774 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8775
8776 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8777 See <http://bugs.gnu.org/11825#29>.
8778
8779 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8780
8781 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8782 has no font, use the frame's font. (Bug#11813)
8783 (display_line): Add commentary about displaying truncation glyphs
8784 on GUI frames.
8785 (produce_special_glyphs): Move here from term.c.
8786
8787 * term.c (produce_special_glyphs): Move to xdisp.c.
8788
8789 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8790 section.
8791
8792 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8793
8794 * xdisp.c (display_line): Avoid warning about implicit declaration
8795 of FRAME_FONT.
8796
8797 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8798
8799 * lisp.h: Remove empty conditional.
8800
8801 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8802
8803 * lread.c (load_path_check): Now static.
8804
8805 Fix some minor --with-ns problems found by static checking.
8806 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8807 (x_set_font) [!HAVE_X_WINDOWS]:
8808 * image.c (xpm_load_image) [HAVE_NS]:
8809 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8810 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8811 Remove unused local.
8812 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8813 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8814 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8815 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8816 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8817 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8818 Fix pointer signedness problem.
8819 * xfaces.c (FRAME_X_FONT_TABLE):
8820 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8821
8822 2012-07-07 Glenn Morris <rgm@gnu.org>
8823
8824 * lread.c (load_path_check): New function, split from init_lread.
8825 (init_lread): Reorganize. Motivation:
8826 If EMACSLOADPATH is set, check/warn about that rather than the
8827 defaults, which we are not going to use. Hence we can remove
8828 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8829 Don't warn if site-lisp directories are missing.
8830 If not installed, start from a blank load-path, since
8831 PATH_LOADSEARCH refers to the eventual installation directories.
8832
8833 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8834
8835 Support truncation and continuation glyphs on GUI frames, when
8836 fringes are disabled. (Bug#11832)
8837 * xdisp.c (init_iterator): Get dimensions of truncation and
8838 continuation glyphs even if on GUI frames.
8839 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8840 or both, are absent.
8841 (start_display, move_it_in_display_line_to): Handle the case of a
8842 GUI frame without a fringe to display continuation or truncation
8843 glyphs.
8844 (insert_left_trunc_glyphs): Support GUI frames: make sure
8845 truncation glyphs overwrite enough glyphs from the current line to
8846 have sufficient space in pixels.
8847 (display_line): Support truncation and continuation glyphs on GUI
8848 frames. If some spare pixels are left on the line after inserting
8849 the truncation glyphs, fill that space with a stretch glyph of a
8850 suitably computed width.
8851
8852 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8853 produce_glyphs, to support GUI sessions.
8854
8855 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>

8858
8859 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8860
8861 Do not require float-time's arg to fit in time_t (Bug#11825).
8862 This works better on hosts where time_t is unsigned, and where
8863 float-time is applied to the (negative) difference between two times.
8864 * editfns.c (decode_time_components): Last arg is now double *,
8865 not int *, and means to store all the result as a double, without
8866 worrying about whether the seconds part fits in time_t.
8867 All callers changed.
8868 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8869 All callers changed.
8870 (Ffloat_time): Do not fail merely because the specified time falls
8871 outside of time_t range.
8872
8873 2012-07-07 Glenn Morris <rgm@gnu.org>
8874
8875 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8885
8886 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8887
8888 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

8890 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8891 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8892 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8893 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8894
8895 * xfont.c (compare_font_names): Redo to omit the need for casts.
8896
8897 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8898
8899 * xfns.c (Fx_change_window_property): Doc fix.
8900 * w32fns.c (Fx_change_window_property): Doc fix.
8901
8902 * w32fns.c (Fx_window_property): Accept the same arguments as the
8903 X Windows version. Doc fix.

8905
8906 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8907 Eli Zaretskii <eliz@gnu.org>
8908

8911 Obsolete settings removed.
8912
8913 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8914
8915 * process.c: Avoid unnecessary calls to gettime.
8916 (wait_reading_process_output): Don't get the time of day
8917 when gobbling data immediately and not waiting, as there's no need
8918 for it in that case. This removes a FIXME.
8919
8920 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8921
8922 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3

8926
8927 Fix marker debugging code.
8928 * marker.c (byte_char_debug_check): Do not perform the check
8929 if buffer is not multibyte.

8931 Call byte_char_debug_check with correct arguments.
8932
8933 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8934
8935 Compile marker debugging code only if ENABLE_CHECKING is defined.

8966 * editfns.c (buildmark): Remove.
8967 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
8968 (save_restriction_save): Use build_marker.
8969 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8970 * window.c (save_window_save): Likewise.
8971
8972 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8973
8974 Do not use Fdelete_overlay in delete_all_overlays
8975 to avoid redundant calls to unchain_overlay.
8976 * buffer.c (drop_overlay): New function.
8977 (delete_all_overlays, Fdelete_overlay): Use it.
8978 * minibuf.c (get_minibuffer): Fix comment.
8979
8980 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8981
8982 Port to OpenBSD 5.1 amd64.
8983 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8984 This is needed for OpenBSD, and should be harmless on all BSD systems.
8985 Also, include <sys/sysctl.h>, as it should be available on all
8986 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8987 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8988 use p_pid member, not kp_proc.pid.
8989
8990 2012-07-06 Glenn Morris <rgm@gnu.org>
8991
8992 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8993
8994 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8995
8996 More xmalloc and related cleanup.
8997 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

9005 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9006 * xterm.c:
9007 Omit needless casts involving void * pointers and allocation.
9008 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9009 as the former is more robust if P's type is changed.
9010 Prefer xzalloc to xmalloc + memset 0.
9011 Simplify malloc-or-realloc to realloc.
9012 Don't worry about xmalloc returning a null pointer.
9013 Prefer xstrdup to xmalloc + strcpy.
9014 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9015 growing it.
9016 * keyboard.c (apply_modifiers_uncached): Prefer local array to

9019 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9020
9021 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9022 hscroll is larger than the line width. Fixes long and futile
9023 looping inside extend_face_to_end_of_line (on a TTY) producing
9024 glyphs that are not needed and thrown away.
9025
9026 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9027
9028 * marker.c (set_marker_restricted_both): Simplify by using
9029 clip_to_bounds.
9030
9031 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9032
9033 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9034
9035 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
9036
9037 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
9038 not defined (Bug#11768).
9039 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9040 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9041 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9042 followed by gtk_box_set_homogeneous (Bug#11768).
9043 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9044 (update_theme_scrollbar_width, xg_create_scroll_bar):
9045 Use gtk_scrollbar_new (Bug#11768).
9046 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9047 (is_box_type): New function (Bug#11768).
9048 (xg_tool_item_stale_p): Call is_box_type.
9049 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9050 with default display (Bug#11768).
9051
9052 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9053
9054 * xdisp.c (window_hscroll_limited): New function.
9055 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9056 coordinates when window's hscroll is set to insanely large
9057 values. (Bug#11857)
9058
9059 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9060
9061 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9062 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
9063

9120 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9121
9122 * fileio.c (time_error_value): Check the right error number.
9123 Problem reported by Troels Nielsen in
9124 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9125
9126 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9127
9128 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9129 This should be fixed in a better way; see Eli Zaretskii in
9130 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9131 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9132
9133 * fileio.c (time_error_value): Rename from special_mtime.
9134 The old name's problems were noted by Eli Zaretskii in
9135 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9136
9137 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9138 This variable's comment says Emacs needs at least one GDB-visible
9139 symbol of type enum pvec_type, to work around GDB problems.
9140 The symbol's value doesn't matter.
9141
9142 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9143 that causes compilation to fail on pre-C99 compilers.
9144
9145 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9146
9147 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9150 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9151
9152 * buffer.c (init_buffer_once): Fix initialization of
9153 headers for buffer_defaults and buffer_local_symbols.
9154 Reported by Juanma Barranquero <lekktu@gmail.com>.
9155
9156 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9157
9158 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9159 * lisp.h (enum pvec_type): Use fewer bits.
9160 (PSEUDOVECTOR_SIZE_BITS): New constant.
9161 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9162 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9163 change in pvec_type.
9164 (PSEUDOVECTOR_TYPEP): New macro.
9165 (TYPED_PSEUDOVECTORP): Use it.
9166 * fns.c (internal_equal): Adapt code to extract pvectype.
9167 * emacs.c (gdb_pvec_type): Update type.
9168 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9169 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9170 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9171 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9172 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9173 abusing vector->header.next.nbytes.
9174 (live_vector_p): Use PVEC_TYPE.
9175 (mark_object): Adapt code to extract pvectype. Use switch.
9176
9177 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9178
9179 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9180 Tighten new eassert a bit.
9181
9182 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9183
9184 Fix compilation with --enable-gcc-warnings and -O1
9185 optimization level.
9186 * doprnt.c (doprnt): Change type of tem to int, initialize
9187 to avoid compiler warning. Add eassert.
9188 * search.c (simple_search): Initialize match_byte to avoid
9189 compiler warning. Add eassert.
9190
9191 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9192
9193 Avoid weird behavior with large horizontal scrolls.
9194 Without this change, for example, large hscroll values would
9195 mess up Emacs's display on Fedora 15 x86, presumably due to
9196 overflows in int calculations in the display code.
9197 Also, if buffers had long lines, Emacs would freeze.
9198 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9199 (set_window_hscroll): New function, containing the old guts of
9200 Fset_window_hscroll. Return the clipped value.
9201 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9202 This avoids the need to check against PTRDIFF_MAX.
9203
9204 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9205
9206 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9207
9208 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9209
9210 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9211
9212 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9213 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9214 since GCC 4.4.6 issues a bogus warning for them.
9215
9216 Fix bugs in file timestamp newness comparisons.
9217 * fileio.c (Ffile_newer_than_file_p):
9218 * lread.c (Fload): Use full timestamp resolution of files,
9219 not just the 1-second resolution, so that files that are only
9220 slightly newer still count as newer.
9221 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9222 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9223
9224 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9225
9226 * fileio.c: Improve handling of file time marker. (Bug#11852)
9227 (special_mtime): New function.
9228 (Finsert_file_contents, Fverify_visited_file_modtime):
9229 Use it to set special mtime values consistently.
9230
9231 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9232
9233 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9234 marker for non-existing file. (Bug#11852)
9235
9236 2012-07-03 Glenn Morris <rgm@gnu.org>
9237
9238 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9239 and did not make it into globals.h).
9240
9241 2012-07-03 Tom Tromey <tromey@redhat.com>
9242
9243 * window.c (Fset_window_margins, Fset_window_fringes)

9286
9287 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9288 values which aren't power of 2.
9289 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9290 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9291 accordingly.
9292
9293 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9294
9295 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9296
9297 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9298
9299 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9300
9301 * alloc.c (allocate_vector_block): Remove redundant
9302 calls to mallopt if DOUG_LEA_MALLOC is defined.
9303 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9304 avoid calls to mallopt if zero_vector is returned.
9305
9306 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9307
9308 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES

9311
9312 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9313
9314 Cleanup basic buffer management.
9315 * buffer.h (struct buffer): Change layout to use generic vector
9316 marking code. Fix some comments. Change type of 'clip_changed'
9317 to bitfield. Remove unused #ifndef old.
9318 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9319 (GET_OVERLAYS_AT): Fix indentation.
9320 (for_each_per_buffer_object_at): New macro.

9324 * alloc.c (allocate_buffer): Adjust to match new layout of
9325 struct buffer. Fix comment.
9326 (mark_overlay): New function.
9327 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9328 Lisp area of struct buffer.
9329 (mark_object): Use it. Adjust marking of misc objects
9330 and related comments.
9331
9332 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9333
9334 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9335 wrapper that is not needed because the wrapped code is a no-op (zero
9336 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9337 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9338
9339 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9340
9341 * alloc.c (mark_buffer): Simplify. Remove prototype.
9342 (mark_object): Add comment. Reorganize marking of vector-like
9343 objects. Use CHECK_LIVE for all vector-like objects except buffers
9344 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9345 Avoid redundant calls to mark_vectorlike for bool vectors.
9346
9347 2012-06-30 Glenn Morris <rgm@gnu.org>
9348
9349 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9350
9351 * epaths.in (PATH_SITELOADSEARCH): New.
9352 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9353 This is rather than relying on --enable-locallisppath elements
9354 having "site-lisp" in their names. (Bug#10208#25, 11658)
9355
9356 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9357
9358 * w32proc.c (sys_select): Accept and ignore one more argument.
9359
9360 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9361
9362 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9363 (pselect) [!MS_DOS]: Redirect to sys_select.
9364
9365 * sysdep.c: Don't include dos.h and dosfns.h.
9366
9367 * process.c (sys_select):
9368 * msdos.c (sys_select): Accept one more argument and ignore it.
9369
9370 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9371 adapt data types and code to that.
9372
9373 * dosfns.c:
9374 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9375 which clashes with the gnulib function of the same name.
9376
9377 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9378
9379 * font.c (font_style_to_value, font_style_symbolic)
9380 (font_prop_validate_style): Add type checks for values in
9381 font_style_table.

9390 * xdisp.c (try_window_id): Undo last change.
9391
9392 * w32.c (getwd): Adjust commentary about startup_dir.
9393 (init_environment): Always call sys_access, even in non-MSVC
9394 builds. Don't chdir to the directory of the Emacs executable.
9395 This undoes code from 1997 which was justified by the need to
9396 "avoid conflicts when removing and renaming directories". But its
9397 downside was that every relative file name was being interpreted
9398 relative to the directory of the Emacs executable, which can never
9399 be TRT. In particular, it broke sys_access when called with
9400 relative file names.
9401 (sys_access): Map GetLastError to errno.

9448 Adjust users accordingly.
9449 * xdisp.c (try_cursor_movement): Replace type check with eassert.

9594
9595 Use sprintf return value instead of invoking strlen on result.
9596 In the old days this wasn't portable, since some sprintf
9597 implementations returned char *. But they died out years ago and
9598 Emacs already assumes sprintf returns int.
9599 Similarly for float_to_string.
9600 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

9607 * xfns.c (syms_of_xfns):
9608 Use sprintf or float_to_string result to avoid need to call strlen.
9609 * data.c (Fnumber_to_string):
9610 Use make_unibyte_string, since the string must be ASCII.
9611 * lisp.h, print.c (float_to_string): Now returns int length.
9612 * term.c (produce_glyphless_glyph):
9613 Use sprintf result rather than recomputing it.
9614
9615 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9616 * Makefile.in (ALL_CFLAGS):

9639 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9640
9641 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9642 sprintf already null-terminates its output.
9643
9644 * xfns.c (x_window): Remove redundant cast.
9645
9646 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9647
9648 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9649 `const char *' to `char *' to avoid compiler warning.

9652
9653 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9654 instead of truncating it to 63 (admittedly a generous limit).

9713 * dispnew.c (Fsleep_for, sit_for):
9714 * keyboard.c (kbd_buffer_get_event):
9715 * process.c (Faccept_process_output):
9716 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9717 This improves on the previous patch, which introduced a bug
9718 when time_t is unsigned and as wide as intmax_t.
9719 See <http://bugs.gnu.org/9000#51>.

9740 All uses changed.
9741 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

9785
9786 Support higher-resolution time stamps (Bug#9000).
9787 The time stamps are only nanosecond-resolution at the C level,
9788 since that's the best that any real-world system supports now.
9789 But they are picosecond-resolution at the Lisp level, as that's
9790 easy, and leaves room for future OS improvements.
9791
9792 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9793 (LIBES): Use it.
9794
9795 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9796 Don't get current time unless it's needed.
9797
9798 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9799 now provides it if it's absent.
9800 (start_atimer): Port to higher-res time stamps.
9801 Check for time stamp overflow. Don't get current time more
9802 often than is needed.
9803
9804 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9805 Include systime.h, not time.h.

9809 (Ffile-attributes): File times now have higher resolution.
9810
9811 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9812 (struct image): Timestamp now has higher resolution.
9813
9814 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9815 has at least microseconds now. All uses removed.
9816 (update_frame, update_single_window, update_window, update_frame_1)
9817 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9818 (duration_to_sec_usec): Remove; no longer needed.

9827 (make_time): Now static.
9828 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.

9830 do that.
9831
9832 * fileio.c: Include <stat-time.h>
9833 (Fcopy_file): Copy higher-resolution time stamps.
9834 Prefer to set the time stamp via a file descriptor if that works.
9835 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9836 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)

9851 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9852 Port to higher-resolution time stamps. Do not assume time_t is signed.
9853 (decode_timer): New function. Timers are now vectors of length 9,

9855 (timer_check_2): Use it.
9856
9857 * nsterm.m (select_timeout, timeval_subtract): Remove.
9858 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9859 as they're a bit more accurate and handle overflow better.
9860 (ns_select): Change prototype to be compatible with pselect.
9861 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9862 * nsterm.h (ns_select): Adjust prototype.
9863
9864 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes

9884 (Fprocess_attributes): Now generates ns-resolution time stamps.
9885
9886 * sysdep.c: Include utimens.h. Don't include utime.h
9887 or worry about struct utimbuf; gnulib does that for us now.
9888 (gettimeofday): Remove; gnulib provides a substitute.
9889 (make_timeval): New function.
9890 (set_file_times): Now sets ns-resolution time stamps.
9891 New arg FD; all uses changed.
9892 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9893 (system_process_attributes):
9894 Now returns ns-resolution time stamp. All uses changed.
9895 Check for time stamp overflow.
9896
9897 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9898 provides a substitute now.
9899
9900 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9901 since it guarantees struct timespec.
9902 (EMACS_TIME): Now struct timespec, so that we can support
9903 ns-resolution time stamps.
9904 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9905 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9906 (EMACS_USECS): Remove.
9907 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9908 so multiply the arg by 1000 before storing it.
9909 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9910 New macros.

9918 (make_timeval, make_lisp_time, decode_time_components): New decls.
9919 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9920 that it mishandled time_t overflow. You can't compare by subtracting!
9921 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9922 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

9933 (w32_get_internal_run_time):
9934 Port to higher-resolution Emacs time stamps.
9935 (ltime): Now accepts single 64-bit integer, as that's more convenient
9936 for callers.
9937
9938 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9939
9940 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9941 for compatibility with pselect. Support ns-resolution time stamps.
9942

9944
9945 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9946 Check for time stamp overflow, and support ns-resolution time stamps.
9947
9948 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9949 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9950 (timeval_subtract): Remove; no longer needed.
9951 (XTflash, XTring_bell, x_wait_for_event):
9952 Port to ns-resolution time stamps. Don't assume time_t is signed.

9958 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9959
9960 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9961 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9962 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9963 staticidx goes up to 1597 out of 1600 = 0x640.)
9964
9965 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9966
9967 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9968 Otherwise, the umask might be mistakenly 0 while handling input signals.

9978 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9979 access to `contents' member of Lisp_Vector objects with AREF and ASET
9980 where appropriate.

9991 Callers changed.
9992 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9993 since tty frames can be explicitly named.
9994 (prepare_menu_bars): Likewise.
9995
9996 * term.c (Ftty_top_frame): New function.
9997
9998 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9999
10000 Port byte-code-meter to modern targets.
10001 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10002 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10003 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10004 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10005 (METER_1, METER_2): Simplify.

10012
10013 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10014 gets killed during executing of this function (Bug#11665).
10015 Try to always return Qt when the buffer has been actually killed.
10016 (Vkill_buffer_query_functions): In doc-string say that functions
10017 run by this hook should not change the current buffer.
10018
10019 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10020
10021 Fix recently-introduced process.c problems found by static checking.

10040
10041 * lisp.h (eassert): Assume C89 or later.
10042 This removes the need for CHECK.
10043 (CHECK): Remove. Its comments about always evaluating its
10044 argument were confusing, as 'eassert' typically does not evaluate
10045 its argument.
10046
10047 * coding.c (produce_chars): Use ptrdiff_t, not int.
10048
10049 * xterm.c (x_draw_underwave): Check for integer overflow.

10144 If all the glyphs of the glyph row came from strings, and we have no
10145 cursor positioning clues, put the cursor on the first glyph of the
10146 row.
10147 (handle_face_prop): Use chunk-relative overlay string index when
10148 indexing into it->string_overlays array. (Bug#11653)
10149 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not

10230 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
10231 -DUSE_LSB_TAG=0, to override the automatically-selected default.
10232 USE_LSB_TAG now is always defined to be either 0 or 1.
10233 All uses changed.
10234 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
10235 code works fine either way, and efficiency is not a concern here,
10236 as the union type is for debugging, not for production.
10237 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10238 Use an inline function on all platforms when using the union type,
10239 since this is simpler and 'static inline' can be used portably
10240 within Emacs now.
10241 (LISP_INITIALLY_ZERO): New macro.
10242 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
10243 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

10324
10325 * xdisp.c (vmessage): Treat frame message as multibyte.
10326 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
10327 would generate the diagnostic "Making \302\247 buffer-local while
10328 let-bound!".
10329

10331
10332 * dispnew.c (showing_window_margins_p): Undo last change, which

10355 * lisp.h (struct vectorlike_header): New field `nbytes',
10356 adjust comment accordingly.
10357 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'

10374 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
10375 (init_alloc_once): Add call to init_vectors.

10380
10381 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10382
10383 * doprnt.c (doprnt): Truncate multibyte char correctly.
10384 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10385 would mishandle a string argument "Xc" if X was a multibyte
10386 character of length 2: it would truncate after X's first byte
10387 rather than including all of X.
10388
10389 2012-06-06 Chong Yidong <cyd@gnu.org>
10390

10433 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
10434 and DEFVAR it. Update all users.
10435
10436 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
10437
10438 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10439
10440 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:

10444 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10445

10452
10453 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10454
10455 For a 'struct window', replace some Lisp_Object fields to
10456 bitfields where appropriate, remove unused fields.
10457 * window.h (struct window): Remove unused 'last_mark_x' and
10458 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10459 change its type from Lisp_Object to bitfield.
10460 Change type of 'force_start', 'optional_new_start',
10461 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

10470 and 'double' in a couple of places.
10471
10472 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10473
10474 * xdisp.c (handle_stop): Detect whether we have overlay strings
10475 loaded by testing it->current.overlay_string_index to be
10476 non-negative, instead of checking whether n_overlay_strings is
10477 positive. (Bug#11587)
10478
10479 2012-05-31 Chong Yidong <cyd@gnu.org>
10480

10485 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10486
10487 * search.c (search_buffer): Remove calls to
10488 r_alloc_inhibit_buffer_relocation, as it is now called by
10489 maybe_unify_char, which was the cause of relocation of buffer text
10490 in bug#11519.
10491
10492 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10493
10494 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10495 for the duration of call to load_charset, to avoid problems with

10497 pointers.
10498
10499 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10500 decrement the inhibition flag, instead of just setting or
10501 resetting it.

10503 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10504
10505 Remove obsolete '#define static' cruft.
10506 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10507 This #undef was "temporary" in 2000; it is no longer needed
10508 now that '#define static' has gone away.
10509 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10510 (gray_bitmap_bits): Remove; no longer needed.

10519 Define only on platforms that need it.
10520 * emacs.c: Include <sys/gmon.h> when profiling.
10521 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10522 (__executable_start): Remove decl, since lisp.h does it now.
10523 (safe_bcopy): Remove decl; no longer has that name.
10524 (main): Coalesce #if into single bit of code, for simplicity.
10525 Cast pointers to uintptr_t, since standard libraries want integers
10526 and not pointers.
10527 * lisp.h (__executable_start): New decl.
10528
10529 2012-05-31 Glenn Morris <rgm@gnu.org>
10530

10553
10554 Do not create empty overlays with the evaporate property (Bug#9642).
10555 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10556 Bug#9642, but explicitly check that the buffer the overlay would
10557 be moved to is live and rearrange lines to make sure that errors
10558 will not put the overlay in an inconsistent state.
10559 (Fdelete_overlay): Cosmetics.
10560
10561 2012-05-28 Eli Zaretskii <eliz@gnu.org>

10567 (Bug#11513)
10568
10569 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
10570 by calling BringWindowToTop.

10573 (WM_EMACS_END): Increase by one.
10574
10575 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10576
10577 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10578 This avoids undefined behavior that might cause the eassert
10579 to not catch an out-of-range value.
10580
10581 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10582

10595 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10596
10597 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10598 Only r_alloc_inhibit_buffer_relocation needed to be added;
10599 the others were already declared.
10600
10601 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10602 before checking whether it's out of range. Put the check inside
10603 eassert. See
10604 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10605
10606 2012-05-27 Ken Brown <kbrown@cornell.edu>
10607
10608 * callproc.c (Fcall_process): Restore a line that was accidentally
10609 commented out in the 2011-02-13 change (bug#11547).

10620 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10621
10622 * search.c (search_buffer): Use it to inhibit relocation of buffer
10623 text while re_search_2 is doing its job, because re_search_2 is
10624 passed C pointers to buffer text. (Bug#11519)
10625
10626 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10627 Update value to 24.
10628
10629 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10630 state after an additional call to move_it_in_display_line_to, keep
10631 the values of it->max_ascent and it->max_descent found for the
10632 entire line.
10633 (pos_visible_p): Revert the comparison against bottom_y to what it
10634 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.

10638
10639 Fix coding-related core dumps with gcc -ftrapv.
10640 The code was computing A - B, where A and B are pointers, and B is
10641 random garbage. This can lead to core dumps on platforms that
10642 have special pointer registers, and it also leads to core dumps on
10643 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10644 A - B only when B is initialized properly.
10645 * coding.c (coding_set_source, coding_set_destination): Return void.
10646 (coding_change_source, coding_change_destinations): New functions,
10647 with the old behaviors of coding_set_source and coding_set_destination.
10648 All callers that need an offset changed to use these new functions.
10649
10650 2012-05-26 Glenn Morris <rgm@gnu.org>
10651
10652 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

10654 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10655
10656 Extend mouse support on W32 text-mode console.
10657 * xdisp.c (draw_row_with_mouse_face):
10658 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10659
10660 * w32console.c: Include window.h.
10661 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10662 New functions.
10663 (initialize_w32_display): Initialize mouse-highlight data.
10664
10665 * w32inevt.c: Include termchar.h and window.h.
10666 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10667 moves, call note_mouse_highlight. If help_echo changed, call
10668 gen_help_event to produce help-echo message in the echo area.
10669 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10670 highlight info.
10671
10672 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10673
10674 * lread.c (read1): Simplify slightly to avoid an overflow warning
10675 with GCC 4.7.0 on x86-64.
10676
10677 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10678
10679 * bidi.c (bidi_mirror_char): Revert last change: an int is
10680 definitely wide enough here.
10681
10682 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10683
10684 Fix integer width and related bugs (Bug#9874).
10685 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
10686 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)

10694 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10695 (allocate_pseudovector):
10696 Use int, not EMACS_INT, where int is wide enough.
10697 (inhibit_garbage_collection, Fgarbage_collect):
10698 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10699 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10700 int might not be wide enough.
10701 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10702 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

10716 (Foverlay_recenter, last_overlay_modification_hooks_used)
10717 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10718 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10719 (validate_region): Omit unnecessary test for b <= e,
10720 since that's guaranteed by the previous test.
10721 (adjust_overlays_for_delete): Avoid pos + length overflow.
10722 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10723 (report_overlay_modification):
10724 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10725 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10726 Omit pointer cast, which isn't needed anyway, and doesn't work
10727 after the EMACS_INT -> ptrdiff_t change.
10728 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10729 * buffer.h: Adjust decls to match defn changes elsewhere.
10730 (struct buffer_text, struct buffer):
10731 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10732 Use EMACS_INT, not int, where int might not be wide enough.
10733 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10734 not int, to avoid needless 32-bit limit on 64-bit hosts.
10735 (exec_byte_code): Use tighter memory-full test, one that checks
10736 for alloca overflow. Don't compute the address of the object just
10737 before an array, as that's not portable. Use EMACS_INT, not
10738 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10739 * callint.c (Fcall_interactively):
10740 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10741 * callproc.c (call_process_kill, Fcall_process):
10742 Don't assume pid_t fits into an Emacs fixnum.
10743 (call_process_cleanup, Fcall_process, child_setup):
10744 Don't assume pid_t fits into int.
10745 (call_process_cleanup, Fcall_process, delete_temp_file)

10747 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10748 (Fcall_process): Simplify handling of volatile integers.
10749 Use int, not EMACS_INT, where int will do.
10750 * casefiddle.c (casify_object, casify_region, operate_on_word)
10751 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10752 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10753 (casify_object): Avoid integer overflow when overallocating buffer.
10754 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10755 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10756 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10757 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10758 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10759 integers are now checked earlier. All uses replaced with XINT.
10760 (ccl_driver):
10761 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10762 For CCL_MapSingle, check that content and value are in int range.
10763 (ccl_driver, Fregister_code_conversion_map):
10764 Check that Vcode_version_map_vector is a vector.
10765 (resolve_symbol_ccl_program): Check that vector header is in range.
10766 Always copy the vector, so that we can check its contents reliably
10767 now rather than having to recheck each instruction as it's being
10768 executed. Check that vector words fit in 'int'.
10769 (ccl_get_compiled_code, Fregister_ccl_program)
10770 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10771 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10772 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10773 contents are in range.
10774 (Fccl_execute_on_string): Check that status is in range.
10775 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10776 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10777 Accept and return EMACS_INT, not int, because callers can pass values
10778 out of 'int' range.
10779 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10780 (multibyte_chars_in_text, parse_str_as_multibyte)

10782 (str_as_unibyte, str_to_unibyte, string_count_byte8)
10783 (string_escape_byte8, Fget_byte):
10784 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10785 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10786 avoid mishandling large integers.
10787 * character.h: Adjust decls to match defn changes elsewhere.
10788 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10789 (Ffind_charset_region):
10790 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10791 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
10792 (load_charset_map_from_vector, Fdefine_charset_internal):
10793 Don't assume fixnum fits in int.
10794 (load_charset_map_from_vector, Fmap_charset_chars):
10795 Remove now-unnecessary CHECK_NATNUMs.
10796 (Fdefine_charset_internal): Check ranges here, more carefully.
10797 Don't rely on undefined behavior with signed left shift overflow.
10798 Don't assume unsigned int fits into fixnum, or that fixnum fits
10799 into unsigned int. Don't require max_code to be a valid fixnum;
10800 that's not true for gb10830 4-byte on a 32-bit host. Allow
10801 invalid_code to be a cons, for the same reason. Require code_offset
10802 to be a character. Avoid int overflow if max_char is close
10803 to INT_MAX.
10804 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10805 this is intended anyway and avoids some undefined behavior.
10806 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10807 INDEX_TO_CODE_POINT, as that's what it expects.
10808 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10809 * charset.h (DECODE_CHAR): Return int, not unsigned;
10810 this is what was intended anyway, and it avoids undefined behavior.
10811 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10812 integer-overflow issues.
10813 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10814 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10815 where the argument is EMACS_INT, and this behavior is not intended.
10816 * chartab.c (Fmake_char_table, Fset_char_table_range)
10817 (uniprop_get_decoder, uniprop_get_encoder):
10818 Don't assume fixnum fits in int.
10819 * cmds.c (move_point): New function, that does the gist of
10820 Fforward_char and Fbackward_char, but does so while checking
10821 for integer overflow more accurately.
10822 (Fforward_char, Fbackward_char): Use it.
10823 (Fforward_line, Fend_of_line, internal_self_insert)
10824 (internal_self_insert):
10825 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10826 Fix a FIXME, by checking for integer overflow when calculating
10827 target_clm and actual_clm.

10857 (Funencodable_char_position, Fcheck_coding_systems_region)
10858 (get_translation, handle_composition_annotation, consume_chars):
10859 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10860 (consume_chars): Rewrite to not calculate an address outside buffer.
10861 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10862 Don't access memory outside of the args array.
10863 (Fdefine_coding_system_internal): Check for charset-id overflow.
10864 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10865 result of ENCODE_CHAR.
10866 * coding.h: Adjust decls to match defn changes elsewhere.
10867 (struct coding_system):
10868 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10883 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10884 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
10885 Do not attempt to compute the address of the object just before a
10886 buffer; this is not portable.
10887 (Faref, Faset):
10888 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10958 (Fformat_time_string): Remove now-unnecessary check.
10959 lisp_time_argument checks for out-of-range usec now.
10960 Use ptrdiff_t, not size_t, where ptrdiff_t will do.
10961 * emacs.c (gdb_valbits, gdb_gctypebits): Now int, not EMACS_INT.

11642
11643 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11644 and right-margin display specs even if the spec is invalid or we
11645 are on a TTY, and thus unable to display on the fringes.
11646 That's because the text with the property will not be displayed anyway,
11647 so we need to signal to the caller that this is a "replacing"
11648 display spec. This fixes display when the spec is invalid or we
11649 are on a TTY.
11650
11651 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11652
11653 * unexaix.c (make_hdr): Fix typo in prototype.
11654 This bug broke the build on AIX. Problem reported by Gilles Pion.
11655
11656 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11657
11658 * keyboard.c (kbd_buffer_get_event): Read special events also in
11659 batch mode. (Bug#11415)
11660
11661 2012-05-12 Glenn Morris <rgm@gnu.org>
11662
11663 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11664
11665 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11666
11667 * lisp.mk (lisp): Add newcomment.elc.
11668
11669 2012-05-12 Glenn Morris <rgm@gnu.org>
11670
11671 * Makefile.in (MKDIR_P): New, set by configure.
11672 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11673
11674 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11675
11676 Remove unused function hourglass_started.
11677 * dispextern.h (hourglass_started):
11678 * w32fns.c (hourglass_started):
11679 * xdisp.c (hourglass_started): Remove.
11680
11681 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11682
11683 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11684 Update dependencies.
11685
11686 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11687
11688 * xgselect.c (xg_select): Put maxfds+1 into a var.
11689 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11690
11691 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11692
11693 2012-05-10 Dave Abrahams <dave@boostpro.com>
11694
11695 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11696 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11697
11698 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11699
11700 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11701 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11702 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11703 Initialize xd_registered_buses.
11704
11705 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11706
11707 Untag more efficiently if USE_LSB_TAG.
11708 This is based on a proposal by YAMAMOTO Mitsuharu in
11709 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11710 For an admittedly artificial (nth 8000 longlist) benchmark on
11711 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11712 Emacs's overall text size by 1%.
11713 * lisp.h (XUNTAG): New macro.
11714 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11715 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11716 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11717 * eval.c (Fautoload):
11718 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11719 * frame.h (XFRAME): Use XUNTAG.
11720
11721 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11722 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11723 Remove unportable assumptions about print widths of types like
11724 dbus_uint32_t.
11725 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11726 intptr_t when converting between pointer and integer, to avoid GCC
11727 warnings about wrong width.
11728
11729 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11730
11731 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11732 stack for each reader_thread, instead of defaulting to 8MB
11733 determined by the linker. This avoids failures in creating
11734 subprocesses on Windows 7, see the discussion in this thread:
11735 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11736
11737 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11738
11739 Fix up display of the *Minibuf-0* buffer in the mini window.
11740 * keyboard.c (read_char): Don't clear the echo area if there's no
11741 message to clear.
11742 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11743 contents of *Minibuf-0*) if there's no message displayed in its stead.
11744
11745 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11746
11747 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11748 batch mode.
11749
11750 2012-05-06 Chong Yidong <cyd@gnu.org>
11751
11752 * lisp.mk (lisp): Update.
11753
11754 2012-05-05 Jim Meyering <meyering@redhat.com>
11755
11756 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11757
11758 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11759
11760 * data.c (PUT_ERROR): New macro.
11761 (syms_of_data): Use it. Add new error type `user-error'.
11762 * undo.c (user_error): New function.
11763 (Fprimitive_undo): Use it.
11764 * print.c (print_error_message): Adjust print style for `user-error'.
11765 * keyboard.c (user_error): New function.
11766 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11767
11768 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11769
11770 Do not limit current-time-string to years 1000..9999.
11771 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11772 (Fcurrent_time_string): Support any year that is supported by the
11773 underlying localtime representation. Don't use asctime, as it
11774 has undefined behavior for years outside the range -999..9999.
11775
11776 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11777
11778 Fix race conditions involving setenv, gmtime, localtime, asctime.
11779 Without this fix, interrupts could mess up code that uses these
11780 nonreentrant functions, since setting TZ invalidates existing
11781 tm_zone or tzname values, and since most of these functions return
11782 pointers to static storage.
11783 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11784 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11785 Grow the critical sections to include not just invoking
11786 localtime/gmtime, but also accessing these functions' results
11787 including their tm_zone values if any, and any related TZ setting.
11788 (format_time_string): Last arg is now struct tm *, not struct tm **,
11789 so that the struct tm is saved in the critical section.
11790 All callers changed. Simplify allocation of initial buffer, partly
11791 motivated by the fact that memory allocation needs to be outside
11792 the critical section.
11793
11794 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11795
11796 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11797 with RESET_INTERVAL.
11798
11799 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11800 Remove duplicated buffer name initialization.
11801
11802 2012-05-02 Jim Meyering <jim@meyering.net>
11803
11804 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11805
11806 * xfns.c (x_window): Use xstrdup (Bug#11375).
11807
11808 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11809
11810 * xdisp.c (pos_visible_p): If already at a newline from the
11811 display string before the 'while' loop, don't walk back the glyphs
11812 from it3.glyph_row. Solves assertion violation when the display
11813 string begins with a newline (egg.el). (Bug#11367)
11814
11815 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11816
11817 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11818 Move to simple.el.
11819
11820 2012-05-01 Glenn Morris <rgm@gnu.org>
11821
11822 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11823 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11824 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11825 All were removed before 23.1.
11826
11827 * dispnew.c: Remove HAVE_LIBNCURSES test;
11828 it is always true on relevant platforms.
11829
11830 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11831 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11832
11833 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11834
11835 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11836
11837 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11838 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11839 Remove.
11840
11841 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11842
11843 Do not avoid creating empty evaporating overlays (Bug#9642).
11844 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11845 That is, do not delete an evaporating overlay if it becomes
11846 empty after its bounds are adjusted to fit within its buffer.
11847 This fix caused other problems, and I'm reverting it until we get
11848 to the bottom of them.
11849
11850 2012-04-27 Chong Yidong <cyd@gnu.org>
11851
11852 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11853
11854 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11855
11856 * xdisp.c (pos_visible_p): If the window start position is beyond
11857 ZV, start the display from buffer beginning. Prevents assertion
11858 violation in init_iterator when the minibuffer window is scrolled
11859 via the scroll bar.
11860
11861 * window.c (window_scroll_pixel_based): Likewise.
11862
11863 2012-04-27 Chong Yidong <cyd@gnu.org>
11864
11865 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11866
11867 2012-04-27 Glenn Morris <rgm@gnu.org>
11868
11869 * fileio.c (Fcopy_file, Fset_file_selinux_context):

11871
11872 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11873
11874 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11875 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11876
11877 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11878
11879 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11880 display element, check also the underlying string or buffer
11881 character. (Bug#11341)
11882
11883 * w32menu.c: Include w32heap.h.
11884 (add_menu_item): If the call to AppendMenuW (via
11885 unicode_append_menu) fails, disable Unicode menus only if we are
11886 running on Windows 9X/Me.
11887
11888 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11889
11890 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11891 (xgetint): Add missing shift for LSB tags.
11892
11893 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11894
11895 * keyboard.c (read_char): Don't wipe echo area for select window
11896 events: These might get delayed via `mouse-autoselect-window'
11897 (Bug#11304).
11898
11899 2012-04-24 Juanma Barranquero <lekktu@gmail.com>

11902 manipulation of :loaded-from data.
11903
11904 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11905
11906 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11907 now a cons (bug#11311).
11908
11909 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11910
11911 Do not create empty overlays with the evaporate property (Bug#9642).
11912 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11913 if it becomes empty after its bounds are adjusted to fit within
11914 its buffer. Without this fix, in a nonempty buffer (let ((o
11915 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11916 yields an empty overlay that has the evaporate property, which is
11917 not supposed to happen.
11918
11919 Fix minor GTK3 problems found by static checking.
11920 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11921 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11922 (struct _EmacsFixedClass, emacs_fixed_get_type):
11923 Move decls here from emacsgtkfixed.h, since they needn't be public.
11924 (emacs_fixed_get_type): Now static.
11925 (emacs_fixed_class_init): Omit unused local.
11926 (emacs_fixed_child_type): Remove; unused.

11930 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11931 (EMACS_FIXED_GET_CLASS): Remove; unused.
11932 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11933
11934 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11935 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11936
11937 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11938
11939 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11940 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11941 (__malloc_size_t, __malloc_ptrdiff_t):
11942 Remove. All uses removed, replaced by the definiens if needed,
11943 since we can assume C89 or better now.
11944 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11952 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11953 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11954 Define using prototypes, not old style.
11955 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11956 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11957 (align): Don't assume that signed integer overflow wraps around.
11958 Omit unused local var.
11959 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11960 (_free_internal_nolock, memalign, mallochook, reallochook):
11961 Omit no-longer-needed casts.
11962 (valloc): Use getpagesize, not __getpagesize.
11963 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11964 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11965
11966 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11967
11968 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11969
11970 Move functions from C to Lisp. Make non-blocking method calls
11971 the default. Implement further D-Bus standard interfaces.
11972

11997 Return number of refcounts.
11998 (Fdbus_get_unique_name): Make stronger parameter check.

12014
12015 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
12016 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
12017 Do not assume ptrdiff_t is the same width as 'int'.
12018
12019 * alloc.c: Handle unusual debugging option combinations.
12020 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
12021 since the two debugging options are incompatible.
12022 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
12023 is defined.
12024 (mem_init, mem_insert, mem_insert_fixup):

12051 It is never used otherwise.
12052
12053 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12054
12055 * print.c (print_preprocess): Only check print_depth if print-circle
12056 is nil.
12057 (print_object): Check for cycles even when print-circle is nil and
12058 print-gensym is t, but only check print_depth if print-circle is nil.

12061
12062 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12063 set the status to "failed" and ensure that sentinel is run.
12064
12065 2012-04-20 Glenn Morris <rgm@gnu.org>
12066
12067 * process.c (Fset_process_inherit_coding_system_flag)

12069 (Fmake_network_process, Fmake_serial_process): Doc fix.
12070
12071 2012-04-20 Eli Zaretskii <eliz@gnu.org>
12072
12073 * xdisp.c (string_buffer_position_lim): Limit starting position to
12074 BEGV.
12075 (set_cursor_from_row): If called for a mode-line or header-line
12076 row, return zero immediately.
12077 (try_cursor_movement): If inside continuation line, don't back up
12078 farther than the first row after the header line, if any.
12079 Don't consider the header-line row as "partially visible", even if
12080 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
12081
12082 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

12118 New extern decls, to avoid calling undeclared functions.
12119 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12120 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12121 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12122 (NEED_MEM_INSERT): New macro.
12123 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12124 Remove one incorrect comment and fix another.

12130 (r_alloc_sbrk): Now static.
12131
12132 Improve ralloc.c interface checking.
12133 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

12135 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
12136 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
12137 [REL_ALLOC]: ... to here, to check interface.
12138 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
12139 Remove decls. This fixes an "It stinks!".
12140

12155
12156 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
12157
12158 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
12159 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
12160 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12161 * s/netbsd.h, s/sol2-6.h:
12162 Remove definition of GC_MARK_STACK, since the default now works.
12163 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12164 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12165 no longer the default.
12166 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12167
12168 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

12190
12191 2012-04-11 Daniel Colascione <dancol@dancol.org>
12192
12193 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12194 against is gone. It's better to use vfork now so that when Cygwin
12195 gains a new, working vfork, we use it automatically (bug#10398).
12196

12226 Pass EMACS rather than BUILT_EMACS.
12227

12235 Add convenience `GNUTLS_LOG2i' macro.
12236
12237 * gnutls.c (gnutls_log_function2i): Convenience log function.
12238 (emacs_gnutls_read): Use new log functions,
12239 `gnutls_handshakes_tried' process member, and
12240 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12241 attempts per process (connection).
12242
12243 2012-04-09 Chong Yidong <cyd@gnu.org>
12244

12252 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12253
12254 * xdisp.c (set_cursor_from_row): If the display string appears in
12255 the buffer at position that is closer to point than the position
12256 after the display string, display the cursor on the first glyph of
12257 the display string. Fixes cursor display when a 'display' text
12258 property immediately follows invisible text. (Bug#11094)
12259
12260 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12261
12262 composite.c: use 'double' consistently
12263 * composite.c (get_composition_id): Use 'double' consistently
12264 instead of converting 'float' to 'double' and vice versa; this is
12265 easier to understand and avoids a GCC warning.
12266
12267 2012-04-09 Glenn Morris <rgm@gnu.org>
12268
12269 * Makefile.in: Generate leim-list with bootstrap-emacs, in

12292 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12293 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12294 objects, as mark_maybe_pointer will catch them otherwise.
12295 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12296 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12313 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12314 [!WINDOWSNT]: New macros.
12315 (init_libxml2_functions, libxml2_loaded_p): New functions.

12319 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12320 linked in).

12322 Call init_libxml2_functions before calling libxml2 functions.
12323 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12324
12325 * emacs.c: Don't include libxml/parser.h.
12326 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12327 xmlCleanupParser directly.
12328
12329 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12330
12331 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12332
12333 * indent.c (Fvertical_motion): If there is a display string at
12334 point, use it.vpos to compute how many lines to backtrack after
12335 move_it_to point. (Bug#11133)
12336
12337 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12338
12339 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12340 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12341 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12342 macros related to unification of CJK characters. For the details,

12356
12357 * w32menu.c (is_simple_dialog): Properly check lisp types.

12359
12360 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12361
12362 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12363 position we get to after a call to move_it_to fails the
12364 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12365 only if we wind up in a string from display property. (Bug#11063)
12366
12367 * window.c (Fdelete_other_windows_internal): Invalidate the row
12368 and column information about mouse highlight, so that redisplay
12369 restores it after reallocating the glyph matrices. (Bug#7464)
12370
12371 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12372 string comes from a `display' text property, use the buffer
12373 position of that property as if we actually saw that position in
12374 the row's glyphs.
12375 (move_it_by_lines): Remove the assertion that
12376 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12377 violated when there's a before-string at the beginning of a line.
12378 (Bug#11063)
12379
12380 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12381
12382 * xdisp.c (append_space_for_newline): If the default face was
12383 remapped, use the remapped face for the appended newline.
12384 (extend_face_to_end_of_line): Use the remapped default face for
12385 extending the face to the end of the line.
12386 (display_line): Call extend_face_to_end_of_line when the default
12387 face was remapped. (Bug#11068)
12388
12389 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12390
12391 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

12405 bit length of glyphless.ch to 25 (Bug#11082).
12406
12407 2012-03-26 Chong Yidong <cyd@gnu.org>
12408
12409 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12410 (command_loop_1): Use it; inhibit selection update for
12411 handle-select-window too (Bug#8996).
12412
12413 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12414
12415 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

12436
12437 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12438 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12439 when fetching a multibyte character consumes more bytes than
12440 CHAR_BYTES returns, due to unification of CJK characters in
12441 string_char. (Bug#11073)
12442
12443 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12444
12445 * process.c (wait_reading_process_output): Handle pty disconnect
12446 by refraining from sending oneself a SIGCHLD (bug#10933).
12447
12448 2012-03-22 Chong Yidong <cyd@gnu.org>
12449
12450 * dispextern.h (struct it): New member string_from_prefix_prop_p.
12451
12452 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12453 Mark string as coming from a prefix property.
12454 (handle_face_prop): Use default face for prefix strings (Bug#4281).

12465 Doc fixes.
12466
12467 2012-03-20 Chong Yidong <cyd@gnu.org>
12468
12469 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12470 to reflect default non-nil value of redisplay-dont-pause.
12471
12472 2012-03-19 Kenichi Handa <handa@m17n.org>
12473
12474 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12475 it fit in a valid range (Bug#11003).
12476
12477 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12478
12479 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12480 that is not from display property, accept the row as a "cursor
12481 row" if one of the string's character has a non-nil `cursor'
12482 property. Fixes cursor positioning when there are newlines in
12483 overlay strings, e.g. in icomplete.el. (Bug#11035)
12484
12485 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12486
12487 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12488
12489 2012-03-12 Chong Yidong <cyd@gnu.org>
12490
12491 * eval.c (inhibit_lisp_code): Rename from

12493
12494 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12495 * window.c (run_window_configuration_change_hook)
12496 (syms_of_window): Callers changed.
12497

12501
12502 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12503
12504 2012-03-10 Chong Yidong <cyd@gnu.org>

12507 is visible (Bug#10955).
12508
12509 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12510

12513 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
12514
12515 * gtkutil.c (x_wm_set_size_hint): Use one row in call to

12526 position past the first glyph_row that ends at ZV. (Bug#10902)
12527 (redisplay_window, next_element_from_string): Fix typos in
12528 comments.
12529 (redisplay_window): Pass to move_it_vertically the margin in
12530 pixels, not in screen lines.
12531
12532 2012-03-02 Glenn Morris <rgm@gnu.org>
12533
12534 * buffer.c (buffer-list-update-hook): Doc fix.
12535
12536 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12537
12538 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12539 push_it before setting up the iterator for the first overlay
12540 string, even if we have an empty string loaded.
12541 (next_overlay_string): If there's an empty string on the iterator
12542 stack, pop the stack. (Bug#10903)
12543
12544 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12545
12546 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12547 Suggested by Stefan Monnier in
12548 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12549 * alloc.c (widen_to_Lisp_Object): New static function.
12550 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12551 and widening them to Lisp_Objects. This would work even if
12552 USE_LSB_TAG is defined and wide integers are used, which might
12553 happen in a future version of Emacs.
12554
12555 2012-02-25 Chong Yidong <cyd@gnu.org>
12556
12557 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12561 (x_clipboard_manager_save_all): Print an informative message
12562 before saving to clipboard manager.
12563
12564 2012-02-24 Chong Yidong <cyd@gnu.org>
12565
12566 * keyboard.c (process_special_events): Handle all X selection
12567 requests in kbd_buffer, not just the next one (Bug#8869).
12568
12569 2012-02-23 Chong Yidong <cyd@gnu.org>
12570
12571 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12572 call when setting menu-bar-lines and tool-bar-lines parameters.
12573 (unwind_create_frame_1): New helper function.
12574
12575 * window.c (inhibit_window_configuration_change_hook): New var.
12576 (run_window_configuration_change_hook): Obey it.
12577 (syms_of_window): Initialize it.
12578
12579 2012-02-22 Chong Yidong <cyd@gnu.org>
12580
12581 * xterm.c (x_draw_image_relief): Add missing type check for
12582 Vtool_bar_button_margin (Bug#10743).
12583
12584 2012-02-21 Chong Yidong <cyd@gnu.org>
12585
12586 * fileio.c (Vfile_name_handler_alist): Doc fix.
12587
12588 * buffer.c (Fget_file_buffer): Protect against invalid file
12589 handler return value.
12590
12591 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
12592
12593 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
12594 when computing $valmask.
12595
12596 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12597 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12598 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12599 It's useless in that case, and it can cause problems on hosts
12600 that allocate halves of EMACS_INT values separately.
12601 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12602 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12603 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12604 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12605 it avoids undefined behavior on hosts where shifting right by more
12606 than the word width has undefined behavior.
12607
12608 2012-02-19 Chong Yidong <cyd@gnu.org>
12609
12610 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12611 (Funhandled_file_name_directory, Ffile_name_as_directory)

12613 (Fsubstitute_in_file_name): Protect against invalid file handler
12614 return values (Bug#10845).
12615
12616 2012-02-18 Eli Zaretskii <eliz@gnu.org>
12617

12622
12623 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
12624
12625 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
12626
12627 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
12628 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12629
12630 2012-02-15 Chong Yidong <cyd@gnu.org>
12631
12632 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12633 marked as special. Also, starting docstrings with * is obsolete.
12634

12647
12648 2012-02-12 Chong Yidong <cyd@gnu.org>
12649
12650 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12651 as that creates a dangerous corner case.
12652
12653 * window.c (Fdelete_window_internal): Invalidate the mouse
12654 highlight (Bug#9904).
12655

12695
12696 * image.c (imagemagick-render-type): Change it from a lisp object
12697 to an integer. Move the doc here from the lisp manual.
12698 Treat all values not equal to 0 the same.
12699
12700 2012-02-06 Chong Yidong <cyd@gnu.org>

12732 * character.c (char_width): Return EMACS_INT, not int.
12733 (char_width, c_string_width): Check for overflow when
12734 computing the width; this is possible now that individual
12735 characters can have unbounded width. Problem introduced
12736 by merge from Emacs 23 on 2012-01-19.
12737
12738 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

12746
12747 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

12815 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
12816
12817 * process.c (read_process_output): Use p instead of XPROCESS (proc).

12820 2012-01-19 Martin Rudalics <rudalics@gmx.at>
12821
12822 * window.c (save_window_save, Fcurrent_window_configuration)
12823 (Vwindow_persistent_parameters): Do not use Qstate.

13332
13333 * dispnew.c (adjust_glyph_matrix): Don't verify hash code of mode-

13385 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13386 Otherwise, valgrind does not work on some platforms.
13387 Problem reported by Andreas Schwab in
13388 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13389 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13390 is set, removing the need for VIRT_ADDRESS_VARIES.
13391 (PURE_P): Use a more-efficient implementation that needs just one
13392 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13393 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13394 to 4 (xorl, subq, cmpq, setbe).
13395 * alloc.c (pure): Always extern now, since that's the
13396 VIRT_ADDR_VARIES behavior.
13397 (PURE_POINTER_P): Use a single comparison, not two, for
13398 consistency with the new puresize.h.
13399 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13400 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
13401 Remove VIRT_ADDR_VARIES no longer needed.

13405 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
13406 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13407 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13408 behave as if the cursor position were at the window margin.
13409
13410 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13411 and the cursor position is out of bounds, behave as if the cursor
13412 position were at the window margin. (Bug#10075)
13413
13414 2011-11-18 Chong Yidong <cyd@gnu.org>
13415
13416 * window.c (Fwindow_combination_limit): Make first argument
13417 non-optional, since it is meaningless for live windows like the
13418 selected window.
13419
13420 2011-11-18 Dmitry Antipov <dmantipov@yandex.ru>
13421

13431 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
13432 hash values of the two rows.
13433 (copy_row_except_pointers): Preserve the used[] arrays and the
13434 hash values of the two rows. (Bug#10035)
13435 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13436
13437 * xdisp.c (row_hash): New function, body extracted from
13438 compute_line_metrics.
13439 (compute_line_metrics): Call row_hash, instead of computing the
13440 hash code inline.
13441
13442 * dispnew.c (verify_row_hash): Call row_hash for computing the
13443 hash code of a row, instead of duplicating code from xdisp.c.

13481 * image.c (imagemagick_load_image): Fix typo.
13482
13483 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13484
13485 * xdisp.c (display_line): Move the call to
13486 highlight_trailing_whitespace before the call to
13487 compute_line_metrics, since the latter needs to see the final
13488 faces of all the glyphs to compute ROW's hash value.
13489 Fixes assertion violations in row_equal_p. (Bug#10035)
13490
13491 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13492
13493 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13494 just return (bug#10044).
13495
13496 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13497
13498 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13499 with user-defined heap size. Bump the default size of the temacs
13500 heap to 27MB, to avoid memory warning when running temacs.
13501 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13502
13503 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13504 current_matrix and desired_matrix. (Bug#9990)
13505 (verify_row_hash) [XASSERTS]: New function.
13506 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
13507 that the hash value of glyph rows is correct.

13552 Avoid some portability problems by eschewing 'extern inline' functions.
13553 The trivial performance wins aren't worth the portability hassles; see

13603
13604 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).

13630 (window_box_width, window_box_left, window_box_left_offset)
13631 (window_box_right, window_box_right_offset): Declare extern.
13632 Otherwise, these inline functions do not conform to C99 and
13633 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13634 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13635 * intervals.c (adjust_intervals_for_insertion)
13636 (adjust_intervals_for_deletion): Now extern, because otherwise the
13637 extern inline functions 'offset_intervals' couldn't refer to it.
13638 (static_offset_intervals): Remove.
13639 (offset_intervals): Rewrite using the old contents of
13640 static_offset_intervals. The old version didn't conform to C99
13641 because an extern inline function contained a reference to an
13642 identifier with static linkage.

13664 (Fwindow_vscroll): Doc fix.
13665 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
13666 argument, since it makes no sense to pass a live window and for
13667 consistency with window-child.

13812
13813 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,

13876 New functions.
13877 (w32font_open_internal, compute_metrics):
13878 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13879 instead of calling the "wide" APIs directly.
13880
13881 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

13897 non-NULL, regardless of GNUTLS_INITSTAGE.
13898 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13899 an error. Set process slots as soon as we allocate them.
13900
13901 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13902
13903 2011-10-27 Chong Yidong <cyd@gnu.org>
13904
13905 * gnutls.c (emacs_gnutls_deinit): New function.

13942
13943 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13944 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13945 current character, check also for next_en_type being WEAK_EN.
13946 (bidi_resolve_weak): Don't enter the expensive loop if the current
13947 position is before next_en_pos. Record the bidi type of the first
13948 non-ET, non-BN character we find, in addition to its position.
13949 (bidi_level_of_next_char): Invalidate next_en_type when
13950 next_en_pos is over-stepped.

13953
13954 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13955 * editfns.c: Rewrite current-time-zone so that it invokes
13956 the equivalent of (format-time-string "%Z") to get the time zone name.
13957 This fixes a bug when the time zone name contains characters that
13958 need converting from the system time locale to Emacs internal format.
13959 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13960 that patch fixed format-time-string to do the conversion, but
13961 I forgot to fix current-time-zone.
13962 (format_time_string): New function, containing most of
13963 what Fformat_time_string used to contain.
13964 (Fformat_time_string): Rewrite in terms of format_time_string.
13965 This doesn't change this function's behavior.
13966 (current-time-zone): Rewrite to use format_time_string.
13967 This fixes the bug reported by Michael Schierl in
13968 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13969 Jason Rumney's 2007-06-07 change worked around this bug, but
13970 didn't fix it.
13971 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13972
13973 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13974
13975 * xdisp.c (start_display): If the character at POS is displayed
13976 via a display vector, reset IT->current.dpvec_index to zero.
13977 (try_window_reusing_current_matrix): If a line ends in a display
13978 vector or the next line starts in a display vector, continue
13979 redrawing the window even though the character position of
13980 start_row was reached.
13981 (Bug#9771, part 2)
13982
13983 2011-10-18 Chong Yidong <cyd@gnu.org>
13984

13988 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13989
13990 Fix part 3 of bug#9771.
13991 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13992 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13993 non-neutral characters if the current character is a paragraph
13994 separator (a.k.a. Newline). This avoids running the same
13995 expensive loop twice, once when we consume the preceding newline
13996 and the other time when the line actually needs to be displayed.
13997 Avoid the loop when we see neutrals on the base embedding level
13998 following a character whose directionality is the same as the
13999 paragraph's. This avoids running the expensive loop when a line
14000 ends in a long sequence of neutrals, like control characters.
14001 Add assertion against STRONG_AL type. Slightly rearrange code
14002 that determines the type of a neutral given the first non-neutral
14003 that follows it.
14004 (bidi_level_of_next_char): Set next_en_pos to zero when
14005 invalidating its info.
14006
14007 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14008
14009 * xdisp.c (push_display_prop): Determine whether to record string
14010 or buffer position by IT->string, not by IT->method. Allow
14011 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14012 (move_it_vertically_backward): Don't look for character position
14013 immediately after the newline when in a continuation line.
14014 (Bug#9771, part 1)
14015
14016 2011-10-15 Martin Rudalics <rudalics@gmx.at>

14023 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14024 errors in XSetWindowBorder (bug#9310).
14025
14026 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14027
14028 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14029 avoid crash when xmalloc overrun checking is enabled.
14030
14031 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14032
14033 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14034 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14035 cursor motion with <left> and <right> arrow keys.
14036
14037 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14038 some callers set that themselves.
14039
14040 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14041
14042 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14043 display string and the previous row comes from the same string and
14044 is empty. (Bug#9739) (Bug#9738)
14045
14046 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14047
14048 * doc.c (get_doc_string): Encode file name (bug#9735).
14049
14050 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14051
14052 * bidi.c (bidi_level_of_next_char):
14053 * xdisp.c (get_visually_first_element): Remove old incorrect
14054 comments regarding the Unicode Line Separator character.
14055
14056 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14057
14058 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14059
14060 * alloc.c (Fgc_status): Do not access beyond zombies array
14061 boundary if nzombies > MAX_ZOMBIES.
14062 * alloc.c (dump_zombies): Add missing format specifier.
14063
14064 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14065
14066 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14067 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14068
14069 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14070 Some packages use them to denote characters with modifiers.
14071
14072 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14073
14074 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14075 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14076 matching a pp-number. Rename parameter var to var1.
14077
14078 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14079
14080 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14081
14082 2011-10-08 Glenn Morris <rgm@gnu.org>
14083
14084 * callint.c (Fcall_interactively): Give a more explicit error for the
14085 'c' case with a non-character input. (Bug#8479)
14086
14087 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14088
14089 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14090 lines.
14091 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14092 lines that are hscrolled on the left.
14093
14094 * dispnew.c (buffer_posn_from_coords): Account for a possible
14095 presence of header-line. (Bug#4426)
14096
14097 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14098
14099 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14100 Don't advertise functionality which we discourage or doesn't work.
14101
14102 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14103
14104 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14105 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14106 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14107 this makes Emacs dump core during garbage collection on rare
14108 occasions. sizeof is obviously inferior to offsetof here, so
14109 stick with offsetof.
14110 (GC_POINTER_ALIGNMENT): New macro.
14111 (mark_memory): Omit 3rd (offset) arg; caller changed.
14112 Don't assume EMACS_INT alignment is the same as pointer alignment.
14113
14114 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14115
14116 * keyboard.c (read_key_sequence_remapped): New var.
14117 (read_key_sequence): Compute remapping in the right buffer.
14118 (command_loop_1): Use read_key_sequence's remapping directly.
14119
14120 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14121
14122 * dired.c (file_name_completion): Don't expand file name.
14123 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14124 before checking file name handler.
14125
14126 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14127 they've been requested explicitly (bug#9591).
14128
14129 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14130
14131 * keymap.c (Fsingle_key_description): Use make_specified_string
14132 instead of build_string to build string from push_key_description.
14133 (Bug#5193)
14134
14135 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14136
14137 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14138 This fixes a Y2038 bug on 64-bit hosts.
14139 * buffer.c (reset_buffer):
14140 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14141 (Fclear_buffer_auto_save_failure):
14142 Use 0, not -1, to represent an unset failure time, since time_t
14143 might not be signed.
14144
14145 Remove dependency on glibc malloc internals.
14146 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14147 Move back here from lisp.h, but with their new implementations.
14148 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14149 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14150 * charset.c (charset_table_init): New static var.
14151 (syms_of_charset): Use it instead of xmalloc. This removes a
14152 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14153 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14154 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14155 Move back to alloc.c.
14156 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14157 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14158
14159 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14160
14161 * nsterm.m (windowDidResize): Call x_set_window_size only when
14162 ns_in_resize is true. Otherwise set pixelwidth/height and
14163 call change_frame_size (Bug#9628).
14164
14165 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14166
14167 Port --enable-checking=all to Fedora 14 x86-64.
14168 * charset.c (syms_of_charset): Also account for glibc malloc's
14169 internal overhead when calculating the initial malloc maximum.
14170
14171 Port --enable-checking=all to Fedora 14 x86.
14172 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14173 Move to lisp.h.
14174 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14175 (overrun_check_realloc, overrun_check_free):
14176 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14177 That way, xmalloc returns a properly-aligned pointer even if
14178 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14179 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14180 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14181 into account when calculating the initial malloc maximum.
14182 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14183 Move here from alloc.c, so that charset.c can use it too.
14184 Properly align; the old code wasn't right for common 32-bit hosts
14185 when configured with --enable-checking=all.
14186 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14187 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14188
14189 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14190
14191 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14192 use EDOM.
14193
14194 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14195
14196 * xdisp.c (compute_display_string_end): If there's no display
14197 string at CHARPOS, return -1.
14198
14199 * bidi.c (bidi_fetch_char): When compute_display_string_end
14200 returns a negative value, treat the character as a normal
14201 character not covered by a display string. (Bug#9624)
14202
14203 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14204
14205 * lread.c (Fread_from_string): Fix typo in docstring.
14206
14207 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14208
14209 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14210 newline, reseat the iterator instead of bidi-iterating there one
14211 character at a time. (Bug#9610)
14212 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14213 TO_CHARPOS if the bidi iterator is at base embedding level.
14214
14215 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14216
14217 * lread.c (readevalloop): Use correct code for NBSP.
14218 (read1): Likewise. (Bug#9608)
14219
14220 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14221
14222 * dbusbind.c (Fdbus_register_signal): When service is not
14223 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14224
14225 2011-09-25 Glenn Morris <rgm@gnu.org>
14226
14227 * buffer.c (truncate-lines): Doc fix.
14228
14229 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14230
14231 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14232 (Fset_window_next_buffers): Doc fix.
14233
14234 2011-09-24 Glenn Morris <rgm@gnu.org>
14235
14236 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14237

14239
14240 Fix minor problems found by static checking.
14241 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14242 * indent.c (Fvertical_motion): Fix == vs = typo.
14243
14244 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14245
14246 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14247 Default value is now t. Doc fix.
14248
14249 * indent.c (Fvertical_motion): Compute and apply the overshoot
14250 logic when moving up, not only when moving down. Fix the
14251 confusing name and values of the it_overshoot_expected variable;
14252 logic changes accordingly. (Bug#9254) (Bug#9549)
14253
14254 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14255 CHARPOS is covered by a display string which includes newlines.
14256 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14257 is covered by a display string with embedded newlines.
14258
14259 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14260
14261 * dbusbind.c (Fdbus_register_signal): Add match rule to

14265
14266 2011-09-24 Jim Meyering <meyering@redhat.com>
14267
14268 do not ignore write error for any output size
14269 The previous change was incomplete.
14270 While it makes emacs --batch detect the vast majority of stdout
14271 write failures, errors were still ignored whenever the output size is
14272 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14273 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14274 && echo FAIL: ignored write error
14275 FAIL: ignored write error
14276 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14277 && echo FAIL: ignored write error
14278 FAIL: ignored write error
14279 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14280
14281 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14282
14283 * emacs.c (Fkill_emacs): In noninteractive mode exit
14284 non-successfully if a write error occurred on stdout. (Bug#9574)
14285
14286 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14287
14288 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14289 the xassert test.
14290
14291 * dispextern.h (struct it): Update the comment documenting what
14292 can it->OBJECT be.
14293
14294 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14295
14296 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14297 a display string, extend search for cursor position to end of row.
14298 (find_row_edges): If the row ends in a newline from a display
14299 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14300 Handle the case of a display string with multiple newlines.
14301 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14302 non-empty line. Fixes confusing cursor motion with arrow keys at
14303 the beginning of a line that starts with whitespace.
14304
14305 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14306
14307 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14308 (bug#9493).
14309
14310 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14311
14312 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14313 boolean (Bug#9154).
14314
14315 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14316
14317 * xdisp.c (display_line): Record maximum and minimum buffer
14318 positions even if no glyphs were produced (e.g., by a zero-width
14319 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14320 buffer positions that will be removed from the glyph row because
14321 they don't fit.
14322 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14323 column is beyond frame width: don't subtract 1 "pixel" when
14324 computing width of the stretch.
14325 (reseat_at_next_visible_line_start): Undo the change made on
14326 2011-09-17 that saved paragraph information and restored it after
14327 the call to `reseat'. (Bug#9545)
14328
14329 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14330
14331 * xdisp.c (expose_window): Save original value of phys_cursor_on_p

14333
14334 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14335
14336 * search.c (boyer_moore): Take unibyte characters from pattern
14337 literally. (Bug#9458)
14338
14339 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14340
14341 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14342

14344
14345 Fix minor problem found by static checking.
14346 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14347 initialized, to pacify gcc -Wuninitialized.
14348
14349 * fileio.c: Report proper errno when syscall falls.
14350 (Finsert_file_contents): Save and restore errno,
14351 so that report_file_error outputs the correct diagnostic.
14352 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14353
14354 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14355
14356 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14357
14358 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14359
14360 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14361 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14362
14363 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14364
14365 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14366 about the current paragraph and restore it after the call to reseat.
14367
14368 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14369 (bidi_find_paragraph_start): Search back for paragraph beginning
14370 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14371 (bidi_move_to_visually_next): Only trigger paragraph-related
14372 computations when the last character is a newline or at EOB, not
14373 just any NEUTRAL_B. (Bug#9470)
14374
14375 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14376 truncated lines if point is covered by a display string. (Bug#9524)
14377
14378 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14379

14381 (cons_to_x_long): New function.
14382 (lisp_data_to_selection_data): Use it. Correct the test for
14383 short-versus-long data; it was negated. Break out of vector
14384 loop, for efficiency, when a long datum is discovered.
14385
14386 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14387
14388 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14389
14390 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14391
14392 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14393 GCC PR/17406) by declaring this function with external scope.
14394
14395 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14396
14397 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14398 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14399
14400 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14401
14402 * editfns.c (Fformat): Correctly handle text properties on "%%".

14412 of TAB characters in a composition.
14413
14414 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14415
14416 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14417 This occurs when processing a multibyte format.
14418 Problem reported by Wolfgang Jenker.

14422 * xdisp.c (try_cursor_movement): Only check for exact match if
14423 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14424
14425 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14426
14427 Remove unused external symbols.
14428 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14429 * xdisp.c (calc_pixel_width_or_height): Now static.
14430 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14431 * indent.c (check_display_width):
14432 * w32term.c: Fix comment to match code.
14433 * xterm.c, xterm.h (x_catching_errors): Remove.
14434
14435 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14436
14437 * xselect.c: Use signed conversions more consistently (Bug#9498).
14438 (selection_data_to_lisp_data): Assume incoming selection data are
14439 signed integers, not unsigned. This is to be consistent with
14440 outgoing selection data, which was modified to use signed integers
14441 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14442 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14443 expects long, not unsigned long.

14445 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14446

14470 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14471 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14472
14473 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14474
14475 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14476 value for non-existent files.
14477
14478 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14479
14480 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14481 set its "size" to -1. This will set the modtime_size field of
14482 the corresponding buffer to -1, which is what
14483 verify-visited-file-modtime expects for files that do not exist.
14484 (Bug#9139)
14485
14486 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14487
14488 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14489 here ...
14490 * lisp.h: ... from here. push_key_description is no longer
14491 defined in keyboard.c, so its declaration should not be in
14492 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14493 logically belongs with push_key_description.
14494
14495 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14496
14497 * buffer.h: Include <sys/types.h> instead of <time.h>.
14498 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14499 Problem reported by Herbert J. Skuhra.

14539
14540 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14541 Without this fix, the command to link temacs failed due to an
14542 undefined symbol __builtin_isnan. This is because
14543 /usr/include/iso/math_c99.h #defines isnan(x) to
14544 __builtin_isnan(x), but the bundled gcc, which identifies itself
14545 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14546 a __builtin_isnan.
14547 * floatfns.c (isnan): #undef, and then #define to a clone of
14548 what's in data.c.
14549 (Fisnan): Always define, since it's always available now.
14550 (syms_of_floatfns): Always define isnan at the Lisp level.
14551
14552 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14553
14554 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14555
14556 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14557
14558 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14559 The previous code assumed that file offsets (off_t values) fit in
14560 EMACS_INT variables, which is not true on typical 32-bit hosts.
14561 The code messed up by falsely reporting buffer overflow in cases
14562 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14563 when "big" contains more than 2**29 bytes, even though this
14564 inserts just one byte and does not overflow the buffer.
14565 (Finsert_file_contents): Store file offsets as off_t
14566 values, not as EMACS_INT values. Check for overflow when
14567 converting between EMACS_INT and off_t. When checking for
14568 buffer overflow or for overlap, take the offsets into account.
14569 Don't use EMACS_INT for small values where int suffices.
14570 When checking for overlap, fix a typo: ZV was used where
14571 ZV_BYTE was intended.
14572 (Fwrite_region): Don't assume off_t fits into 'long'.
14573 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14574
14575 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14576
14577 * dbusbind.c (xd_signature_cat): Rename from signature_cat.

14579 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14580
14581 sprintf-related integer and memory overflow issues (Bug#9412).
14582
14583 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14584 (esprintf, exprintf, evxprintf): New functions.
14585 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14586 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14587 (modify_event_symbol): Do not assume that the length of
14588 name_alist_or_stem is safe to alloca and fits in int.
14589 (Fexecute_extended_command): Likewise for function name and binding.
14590 (Frecursion_depth): Wrap around reliably on integer overflow.
14591 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14592 since some callers pass EMACS_INT values.
14593 (Fsingle_key_description): Don't crash if symbol name contains more
14594 than MAX_ALLOCA bytes.
14595 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14596 (get_minibuffer): Arg is now EMACS_INT, not int.
14597 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14598 (esprintf, exprintf, evxprintf): New decls.
14599 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14600
14601 * dbusbind.c (signature_cat): New function.
14602 (xd_signature, Fdbus_register_signal):
14603 Do not overrun buffer; instead, report string overflow.
14604
14605 * dispnew.c (add_window_display_history): Don't overrun buffer.
14606 Truncate instead; this is OK since it's just a log.
14607
14608 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14609 even if the time zone offset is outlandishly large.
14610 Don't mishandle offset == INT_MIN.
14611
14612 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14613 when creating daemon; the previous buffer-overflow check was incorrect.
14614
14615 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14616 which has the guts of the old verror function.
14617
14618 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14619 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14620
14621 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14622 (font_unparse_xlfd): Don't blindly alloca long strings.
14623 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14624 fits in int, when using sprintf. Use single snprintf to count
14625 length of string rather than counting it via multiple sprintfs;
14626 that's simpler and more reliable.
14627 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14628 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14629 sprintf, in case result does not fit in int.
14630
14631 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14632 (fontset_from_font): Print it.
14633
14634 * frame.c (tty_frame_count): Now printmax_t, not int.
14635 (make_terminal_frame, set_term_frame_name): Print it.
14636 (x_report_frame_params): In X, window IDs are unsigned long,
14637 not signed long, so print them as unsigned.
14638 (validate_x_resource_name): Check for implausibly long names,
14639 and don't assume name length fits in 'int'.
14640 (x_get_resource_string): Don't blindly alloca invocation name;
14641 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14642 not fit in int.
14643
14644 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14645 (xg_check_special_colors, xg_set_geometry):
14646 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14647
14648 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14649 Use esprintf, not sprintf, in case result does not fit in int.
14650
14651 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14652 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14653 it as a large positive number.
14654 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14655 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14656
14657 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14658 in case result does not fit in int.
14659
14660 * print.c (float_to_string): Detect width overflow more reliably.
14661 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14662 buffer overrun. Don't assume list length fits in 'int'. Treat
14663 print length of 0 as 0, not as infinity; to be consistent with other
14664 uses of print length in this function. Don't overflow print length
14665 index. Don't assume hash table size fits in 'long', or that
14666 vectorlike size fits in 'unsigned long'.
14667
14668 * process.c (make_process): Use printmax_t, not int, to format
14669 process-name gensyms.
14670
14671 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14672
14673 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14674 to avoid potential buffer overrun.
14675
14676 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14677 if X resource line is longer than 512 bytes.
14678
14679 * xfns.c (x_window): Make sprintf buffer a bit bigger
14680 to avoid potential buffer overrun.
14681
14682 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14683
14684 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14685
14686 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14687
14688 Integer overflow fixes for scrolling, etc.
14689 Without these, Emacs silently mishandles large integers sometimes.
14690 For example, "C-u 4294967297 M-x recenter" was treated as if
14691 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14692
14693 * xdisp.c (try_window_id): Check Emacs fixnum range before
14694 converting to 'int'.
14695
14696 * window.c (window_scroll_line_based, Frecenter):
14697 Check that an Emacs fixnum is in range before assigning it to 'int'.
14698 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14699 values converted from Emacs fixnums.
14700 (Frecenter): Don't wrap around a line count if it is out of 'int'
14701 range; instead, treat it as an extreme value.
14702 (Fset_window_configuration, compare_window_configurations):
14703 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14704
14705 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14706 that can exceed INT_MAX. Check that EMACS_INT value is in range
14707 before assigning it to the (possibly-narrower) index.
14708 (match_limit): Don't assume that a fixnum can fit in 'int'.
14709
14710 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14711 exceed INT_MAX.
14712
14713 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14714 (Fvertical_motion): Don't wrap around LINES values that don't fit
14715 in 'int'. Instead, treat them as extreme values. This is good
14716 enough for windows, which can't have more than INT_MAX lines anyway.
14717
14718 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14719
14720 * Require libxml/parser.h to avoid compilation warning.
14721
14722 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14723
14724 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14725 since this reportedly can destroy thread storage.
14726
14727 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14728
14729 * syntax.c (find_defun_start): Update all cache variables if
14730 exiting early (Bug#9401).
14731
14732 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14733
14734 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14735
14736 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14737 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14738 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14739
14740 * term.c (tty_append_glyph): New function.
14741 (produce_stretch_glyph): Static function and its prototype deleted.
14742
14743 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14744 Add prototypes.
14745
14746 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14747
14748 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14749 when checking :margin (Bug#9390).
14750 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14751 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14752 so that the name doesn't mislead. All uses changed.
14753
14754 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14755
14756 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14757 set_tty_hooks.
14758
14759 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14760
14761 * xdisp.c (move_it_to): Don't bail out early when reaching
14762 position beyond to_charpos, if we are scanning backwards.
14763 (move_it_vertically_backward): When DY == 0, make sure we get to
14764 the first character in the line after the newline.
14765
14766 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14767
14768 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14769 (ccl_driver): Do not generate an out-of-range pointer.
14770 (Fccl_execute_on_string): Remove unnecessary check for
14771 integer overflow, noted by Stefan Monnier in
14772 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14773 Remove a FIXME that didn't need fixing.
14774 Simplify the newly-introduced buffer reallocation code.
14775
14776 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14777
14778 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14779
14780 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14781
14782 Integer and memory overflow issues (Bug#9196).
14783
14784 * doc.c (get_doc_string): Rework so that
14785 get_doc_string_buffer_size is the actual buffer size, rather than
14786 being 1 less than the actual buffer size; this makes xpalloc more
14787 convenient.
14788
14789 * image.c (x_allocate_bitmap_record, cache_image):
14790 * xselect.c (Fx_register_dnd_atom):
14791 Simplify previous changes by using xpalloc.
14792
14793 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14794 since either will do and ptrdiff_t is convenient with xpalloc.
14795
14796 * charset.c (charset_table_size)
14797 (struct charset_sort_data.priority): Now ptrdiff_t.
14798 (charset_compare): Don't overflow if priorities differ greatly.
14799 (Fsort_charsets): Don't assume list length fits in int.
14800 Check for size-calculation overflow when allocating sort data.
14801 (syms_of_charset): Allocate an initial charset table that is
14802 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14803
14804 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14805
14806 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14807 The actual value is always <= INT_MAX, and leaving it unsigned made
14808 overflow checking harder.
14809
14810 * dispextern.h (struct glyph_matrix.rows_allocated)
14811 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14812 with xpalloc. The values are still always <= INT_MAX.
14813
14814 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14815
14816 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14817 (SAFE_NALLOCA): New macro.

14822 (revalidate_region_cache, know_region_cache, region_cache_forward)
14823 (region_cache_backward, pp_cache):
14824 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14825 so that ptrdiff_t * can be passed to xpalloc.
14826 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14827 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

14843 (overlay_strings):
14844 Don't update size of array until after memory allocation succeeds,
14845 because xmalloc/xrealloc may not return.
14846 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14847 now that we have proper integer overflow checking.

14849 calculating size of overlay_str_buf.
14850
14851 * callproc.c (Fcall_process): Check for size overflow when
14852 calculating size of args2.
14853 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14854 Normally we prefer signed values, but sticking with ptrdiff_t would
14855 require adding more-complicated checks.
14856
14857 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14858 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

14898 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14899
14900 * emacs.c (main): Do not reallocate argv, since there is a null at
14901 the end that can be overwritten, and this way there's no need to
14902 worry about size-calculation overflow.
14903 (sort_args): Check for size-calculation overflow.
14904
14905 * eval.c (init_eval_once, grow_specpdl): Don't update size until

14912 (x_set_alpha): Do not assume XINT fits in int.
14913
14914 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14915 This is for the members text_lines, text_cols, total_lines, total_cols,
14916 where the system imposes an 'int' limit.
14917
14918 * fringe.c (Fdefine_fringe_bitmap):

15032 (X_LONG_MIN): New macros.
15033 Use them to make the following changes clearer.
15034 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15035 This change doesn't affect the value now, but it may help remind
15036 future maintainers not to raise the value too much later.
15037 (SELECTION_QUANTUM): Remove, replacing with ...
15038 (selection_quantum): ... new function, which avoids overflow.
15039 All uses changed.
15040 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

15049 Redo calculations to avoid overflow.
15050 (x_reply_selection_request): When sending hint, ceiling it at
15051 X_LONG_MAX rather than relying on wraparound overflow to send
15052 something.

15054 (lisp_data_to_selection_data, x_property_data_to_lisp):

15058 Don't store size until memory allocation succeeds.
15059 (x_get_window_property): Plug memory leak on memory exhaustion.
15060 Don't double-block input; malloc is safe here. Don't assume 2**34
15061 - 4 fits in unsigned long. Add an xassert to check
15062 XGetWindowProperty overflow. Be more careful about overflow
15063 calculations, and distinguish size from memory overflow better.
15064 (receive_incremental_selection): When tracing, don't assume
15065 unsigned int is less than INT_MAX.
15066 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15067 harmful) conversions of unsigned short to int.
15068 (lisp_data_to_selection_data): Don't assume that integers
15069 in the range -65535 through -1 fit in an X unsigned short.
15070 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15071 result parameters unless successful. Rely on cons_to_unsigned
15072 to report problems with elements; the old code wasn't right anyway.
15073 (x_check_property_data): Check for int overflow; we cannot use
15074 a wider type due to X limits.

15107 * lisp.h (hash_lookup, hash_put):
15108 * minibuf.c (Ftest_completion):
15109 Use ptrdiff_t for hash table indexes, not int (which is too
15110 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15111 32-bit --with-wide-int hosts).
15112
15113 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15114 Add a FIXME comment about memory leaks.

15119 * character.h (CHAR_WIDTH):
15120 * indent.c (MULTIBYTE_BYTES_WIDTH):
15121 Use sanitize_char_width to avoid undefined and/or bad behavior
15122 with outlandish widths.
15123 * character.h (sanitize_tab_width): Rename from sanitize_width,
15124 now that we have two such functions. All uses changed.

15149 (make_lispy_movement): Use same integer type in forward decl
15150 that is used in the definition.
15151 (read_key_sequence, keyremap_step):
15152 Change bufsize argument back to int, undoing my 2011-03-30 change.
15153 We prefer signed types, and int is wide enough here.
15154 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15155 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15156 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15157 length, not size_t. Use ptrdiff_t for index, not int.
15158 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15159 possibility of integer overflow.

15183 (lookup_image): Remove unnecessary tests.
15184 (xbm_image_p): Locals are now of int, not EMACS_INT,
15185 since parse_image_check makes sure they fit into int.
15186 (png_load, gif_load, svg_load_image):
15187 Prefer int to unsigned where either will do.
15188 (tiff_handler): New function, combining the cores of the
15189 old tiff_error_handler and tiff_warning_handler.
15190 This function is rewritten to use vsnprintf and thereby avoid
15191 stack buffer overflows. It uses only the features of vsnprintf
15192 that are common to both POSIX and native Microsoft.
15193 (tiff_error_handler, tiff_warning_handler): Use it.
15194 (tiff_load, gif_load, imagemagick_load_image):
15195 Don't assume :index value fits in 'int'.
15196 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15197 (imagemagick_load_image): Check that crop parameters fit into
15198 the integer types that MagickCropImage accepts. Don't assume
15199 Vimagemagick_render_type has a nonnegative value. Don't assume
15200 size_t fits in 'long'.
15201 (gs_load): Use printmax_t to print the widest integers possible.
15202 Check for integer overflow when computing image height and width.

15210
15211 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15212 the display spec is of the form `(space ...)'.
15213 (handle_display_spec): Return the value returned by
15214 handle_single_display_spec, not just 1 or zero.
15215 (handle_single_display_spec): If the display spec is of the form
15216 `(space ...)', and specifies display in the text area, return 2
15217 rather than 1.
15218 (try_cursor_movement): Check for the need to scroll more
15219 accurately, and prefer exact match for point under bidi.
15220 Don't advance `row' beyond the last row of the window.
15221
15222 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15223 into disp_prop; all users changed.
15224
15225 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
15226 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
15227 for the text covered by the display property.

15238 buffers, return left-to-right.
15239 (set_cursor_from_row): Consider candidate row a win if its glyph
15240 represents a newline and point is on that newline. Fixes cursor
15241 positioning on the newline at EOL of R2L text within L2R
15242 paragraph, and vice versa.
15243 (try_cursor_movement): Check continued rows, in addition to
15244 continuation rows. Fixes unwarranted scroll when point enters a
15245 continued line of R2L text within an L2R paragraph, or vice versa.
15246 (cursor_row_p): Consider the case of point being equal to
15247 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15248 from the end of a short line to the beginning of a continued line
15249 of R2L text within L2R paragraph.
15250 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

15274 account for the height of the header line. (Bug#8874)
15275
15276 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15277 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15278 candidate is selected by the mouse, and that candidate has a
15279 composed character under the mouse.
15280
15281 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15282 coordinates reported by pos-visible-in-window-p for a composed

15290
15291 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15292 consider it a hit if to_charpos is anywhere in the range of the
15293 composed buffer positions.
15294
15295 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15296
15297 * image.c (gif_load): Don't assume that each subimage has the same
15298 dimensions as the base image. Handle disposal method that is
15299 "undefined" by the gif spec (Bug#9335).
15300
15301 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

15306 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15307
15308 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15309 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15310 from an Org mode buffer to a Speedbar frame.
15311
15312 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15313 a composition, take its buffer position from IT->cmp_it.charpos.
15314 Fixes cursor positioning at the beginning of a line that begins
15315 with a composed character.
15316
15317 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15318
15319 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15320 character bidirectional type, use STRONG_L instead. Fixes crashes
15321 in a buffer produced by `describe-categories'.
15322
15323 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15324 members before the level stack, so they would be saved and
15325 restored when copying iterator state. Fixes incorrect reordering
15326 around TABs covered by display properties.
15327
15328 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15329

15458 Set IT->current to match the bidi iterator unconditionally.
15459 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15460 entry. Force push_it to save on the stack the current
15461 buffer/string position, to be restored by pop_it. Fix flags in
15462 the iterator structure wrt the object coming from a display
15463 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15464 properties. (Bug#9284)

15616 (reseat_at_next_visible_line_start): Use the bidi iterator state
15617 returned by forward_to_next_line_start to restore the state of
15618 it->bidi_it after backing up to previous newline. (Bug#9212)
15619
15620 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15621
15622 * regex.c (re_comp): Protoize.
15623 (re_exec): Fix return type.
15624 (regexec): Fix type of `ret'. (Bug#9203)
15625
15626 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15627
15628 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15629 This is needed if max-image-size is a floating-point number.
15630
15631 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15632
15633 * print.c (print_object): Print empty symbol as ##.
15634
15635 * lread.c (read1): Read ## as empty symbol.
15636
15637 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15638
15639 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15640 setting frame foreground color (Bug#9175).
15641 (x_set_background_color): Likewise.
15642
15643 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15644 contents (Bug#9176).
15645 (EmacsTooltip -init): Remove bezels and add shadows to
15646 tooltip windows.
15647
15648 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15649 or scroll bar (Bug#8470).
15650
15651 * nsfont.m (nsfont_open): Remove assignment to voffset and
15652 unnecessary vars hshink, expand, hd, full_height, min_height.
15653 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15654
15655 * nsterm.h (nsfont_info): Remove voffset field.
15656
15657 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15658
15659 Implement strike-through and overline on NextStep (Bug#8863).
15660
15661 * nsfont.m (nsfont_open): Use underline position provided by font,
15662 instead of hard-coded value of 2.
15663 (nsfont_draw): Call ns_draw_text_decoration instead.
15664
15665 * nsterm.h: Add declaration for ns_draw_text_decoration.
15666
15667 * nsterm.m (ns_draw_text_decoration): New function for drawing
15668 underline, overline, and strike-through.
15669 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15670 ns_draw_text_decoration. Change treatment of cursor drawing to
15671 accommodate underlining, etc.
15672
15673 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15674
15675 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15676 default.
15677
15678 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15679
15680 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15681 Without this fix, if a signal arrives just after memory fills up,
15682 'malloc' might be invoked reentrantly.
15683
15684 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15685 In other words, assume that every image size is allowed, on non-X
15686 hosts. This assumption is probably wrong, but it lets Emacs compile.
15687
15688 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15689
15690 * regex.c (re_iswctype): Convert return values to boolean.
15691
15692 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15693
15694 * xdisp.c (compute_display_string_pos): Don't use cached display
15695 string position if the buffer had its restriction changed.
15696 (Bug#9184)
15697
15698 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15699
15700 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15701
15702 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15703
15704 Integer signedness and overflow and related fixes. (Bug#9079)
15705
15706 * bidi.c: Integer size and overflow fixes.
15707 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15708 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15709 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15710 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15711 (bidi_find_other_level_edge):
15712 Use ptrdiff_t instead of EMACS_INT where either will do.
15713 This works better on 32-bit hosts configured --with-wide-int.
15714 (bidi_cache_ensure_space): Check for size-calculation overflow.
15715 Use % rather than repeated addition, for better worst-case speed.
15716 Don't set bidi_cache_size until after xrealloc returns, because it
15717 might not return.
15718 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15719 (bidi_cache_ensure_space): Also check that the bidi cache size
15720 does not exceed that of the largest Lisp string or buffer. See Eli
15721 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15722
15723 * alloc.c (__malloc_size_t): Remove.
15724 All uses replaced by size_t. See Andreas Schwab's note
15725 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15726
15727 * image.c: Improve checking for integer overflow.
15728 (check_image_size): Assume that f is nonnull, since
15729 it is always nonnull in practice. This is one less thing to
15730 worry about when checking for integer overflow later.
15731 (x_check_image_size): New function, which checks for integer
15732 overflow issues inside X.
15733 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15734 This removes the need for a memory_full check.
15735 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15736 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15737 (xbm_read_bitmap_data): Change locals back to 'int', since
15738 their values must fit in 'int'.
15739 (xpm_load_image, png_load, tiff_load):
15740 Invoke x_create_x_image_and_pixmap earlier,
15741 to avoid much needless work if the image is too large.
15742 (tiff_load): Treat overly large images as if
15743 x_create_x_image_and_pixmap failed, not as malloc failures.
15744 (gs_load): Use x_check_image_size.
15745
15746 * gtkutil.c: Omit integer casts.
15747 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15748 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15749
15750 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15751
15752 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15753 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15754 would wrongly return t on a 64-bit host.
15755
15756 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15757 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15758 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15759 and therefore cause GCC to emit a bogus diagnostic in some cases.
15760
15761 * image.c: Integer signedness and overflow and related fixes.
15762 This is not an exhaustive set of fixes, but it's time to
15763 record what I've got.
15764 (lookup_pixel_color, check_image_size): Remove redundant decls.
15765 (check_image_size): Don't assume that arbitrary EMACS_INT values
15766 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15767 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15768 (tiff_load, imagemagick_load_image):
15769 Check for overflow in size calculations.
15770 (x_create_x_image_and_pixmap): Remove unnecessary test for
15771 xmalloc returning NULL; that can't happen.
15772 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15773 (xpm_color_bucket): Use better integer hashing function.
15774 (xpm_cache_color): Don't possibly over-allocate memory.
15775 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15776 (gif_memory_source):
15777 Use ptrdiff_t, not int or size_t, to record sizes.
15778 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15779 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15780 either works, as we prefer signed integers.
15781 (tiff_read_from_memory, tiff_write_from_memory):
15782 Return tsize_t, not size_t, since that's what the TIFF API wants.
15783 (tiff_read_from_memory): Don't fail simply because the read would
15784 go past EOF; instead, return a short read.
15785 (tiff_load): Omit no-longer-needed casts.
15786 (Fimagemagick_types): Don't assume size fits into 'int'.
15787
15788 Improve hashing quality when configured --with-wide-int.
15789 * fns.c (hash_string): New function, taken from sxhash_string.
15790 Do not discard information about ASCII character case; this
15791 discarding is no longer needed.
15792 (sxhash-string): Use it. Change sig to match it. Caller changed.
15793 * lisp.h: Declare it.
15794 * lread.c (hash_string): Remove, since we now use fns.c's version.
15795 The fns.c version returns a wider integer if --with-wide-int is
15796 specified, so this should help the quality of the hashing a bit.
15797
15798 * emacs.c: Integer overflow minor fix.
15799 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15800 Define only if GNU_LINUX.
15801 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15802
15803 * dispnew.c: Integer signedness and overflow fixes.
15804 Remove unnecessary forward decls, that were a maintenance hassle.
15805 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15806 All uses changed.
15807 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15808 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15809 (prepare_desired_row, line_draw_cost):
15810 Use int, not unsigned, where either works.
15811 (save_current_matrix, restore_current_matrix):
15812 Use ptrdiff_t, not size_t, where either works.
15813 (init_display): Check for overflow more accurately, and without
15814 relying on undefined behavior.
15815
15816 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15817 Remove, replacing with the new symbols in lisp.h. All uses changed.
15818 * fileio.c (make_temp_name):
15819 * filelock.c (lock_file_1, lock_file):
15820 * xdisp.c (message_dolog):
15821 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15822 Use pMd etc. instead.
15823 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15824 replacing the pWIDE etc. symbols removed from editfns.c.
15825
15826 * keyboard.h (num_input_events): Now uintmax_t.
15827 This is (very slightly) less likely to mess up due to wraparound.
15828 All uses changed.
15829
15830 * buffer.c: Integer signedness fixes.
15831 (alloc_buffer_text, enlarge_buffer_text):
15832 Use ptrdiff_t rather than size_t when either will do, as we prefer
15833 signed integers.
15834
15835 * alloc.c: Integer signedness and overflow fixes.
15836 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15837 (__malloc_size_t): Default to size_t, not to int.
15838 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15839 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15840 Prefer ptrdiff_t to size_t when either would do, as we prefer
15841 signed integers.
15842 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15843 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15844 Now const. Initialize with values that are in range even if char
15845 is signed.
15846 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15847 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15848 These functions do the right thing with sizes > 2**32.
15849 (check_depth): Now ptrdiff_t, not int.
15850 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15851 Adjust to new way of storing sizes. Check for size overflow bugs
15852 in rest of code.
15853 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15854 slightly wrong anyway, as it missed one instance of
15855 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15856 (refill_memory_reserve): Omit needless cast to size_t.
15857 (mark_object_loop_halt): Mark as externally visible.
15858
15859 * xselect.c: Integer signedness and overflow fixes.
15860 (Fx_register_dnd_atom, x_handle_dnd_message):
15861 Use ptrdiff_t, not size_t, since we prefer signed.
15862 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15863 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15864 x_dnd_atoms_size and x_dnd_atoms_length.
15865
15866 * doprnt.c: Prefer signed to unsigned when either works.
15867 * eval.c (verror):
15868 * doprnt.c (doprnt):
15869 * lisp.h (doprnt):
15870 * xdisp.c (vmessage):
15871 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15872 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15873 prefer signed arithmetic to avoid comparison confusion.
15874 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15875 but is a bit tricky.
15876
15877 Assume freestanding C89 headers, string.h, stdlib.h.
15878 * data.c, doprnt.c, floatfns.c, print.c:
15879 Include float.h unconditionally.
15880 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15881 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15882 * regex.c: Likewise for stddef.h, string.h.
15883 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15884 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15885 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15886 (STDC_HEADERS): Remove obsolete defines.
15887 * sysdep.c: Include limits.h unconditionally.
15888
15889 Assume support for memcmp, memcpy, memmove, memset.
15890 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15891 * regex.c (memcmp, memcpy):
15892 Remove; we assume C89 now.
15893
15894 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15895 (__malloc_safe_bcopy): Remove; no longer needed.
15896
15897 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15898 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15899 well either way, and we prefer signed to unsigned.
15900
15901 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15902
15903 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15904 closes the connection while we're reading (bug#9182).
15905
15906 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15907
15908 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15909 are specified (Bug#9168).
15910
15911 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15912
15913 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15914 Found by GCC static checking and --with-wide-int on a 32-bit host.
15915
15916 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15917
15918 * xdisp.c (compute_display_string_pos): Fix logic of caching
15919 previous display string position. Initialize cached_prev_pos to
15920 -1. Fixes slow-down at the beginning of a buffer.
15921
15922 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15923
15924 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15925 for attrs[LFACE_FONTSET_INDEX].
15926
15927 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15928
15929 * xml.c (parse_region): Remove unused local
15930 that was recently introduced.
15931
15932 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15933
15934 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15935 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15936
15937 * xdisp.c (move_it_in_display_line_to): Record the best matching
15938 position for TO_CHARPOS while scanning the line, and restore it on
15939 exit if none of the characters scanned was an exact match.
15940 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15941 when exact match is impossible due to invisible text, and the
15942 lines are truncated.
15943
15944 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15945
15946 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15947 for OSX >= 10.7.
15948
15949 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15950
15951 Fix a significant slow-down of cursor motion with C-n, C-p,
15952 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15953 auto-repeat under bidi redisplay in fontified buffers.
15954 * xdisp.c (compute_stop_pos_backwards): New function.
15955 (next_element_from_buffer): Call compute_stop_pos_backwards to
15956 find a suitable prev_stop when we find ourselves before
15957 base_level_stop.
15958 (reseat): Don't look for prev_stop, as that could mean a very long
15959 run.
15960 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15961 <cached_disp_overlay_modiff>: Cache for last found display string
15962 position.
15963 (compute_display_string_pos): Return the cached position if asked
15964 about the same buffer in the same area of character positions, and
15965 the buffer wasn't changed since the time the display string
15966 position was cached.
15967
15968 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15969
15970 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15971 is an integer, which is important for empty lines. (Bug#9149)
15972
15973 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15974
15975 * frame.c (Fmodify_frame_parameters): In tty case, update the
15976 default face if necessary (Bug#4238).
15977
15978 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15979
15980 * editfns.c (Fstring_to_char): No need to explain what a character
15981 is in the docstring (Bug#6576).
15982
15983 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15984
15985 * xml.c (parse_region): Make sure we always return a tree.
15986
15987 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15988
15989 * xml.c (parse_region): If a document contains only comments,
15990 return that, too.
15991
15992 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15993
15994 * xml.c (make_dom): Return comments, too.
15995
15996 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15997
15998 Port to OpenBSD.
15999 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16000 and the surrounding thread.
16001 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16002 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16003 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16004 timer goes off.
16005 * s/openbsd.h (BROKEN_SIGIO): Define.
16006 * unexelf.c (unexec) [__OpenBSD__]:
16007 Don't update the .mdebug section of the Alpha COFF symbol table.
16008
16009 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16010
16011 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16012 (bug#8460).
16013
16014 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16015
16016 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16017 This fixes some race conditions on the permissions of any newly
16018 created file.
16019
16020 * alloc.c (valid_pointer_p): Use pipe, not open.
16021 This fixes some permissions issues when debugging.
16022
16023 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16024 If fchown fails to set both uid and gid, try to set just gid,
16025 as that is sometimes allowed. Adjust the file's mode to eliminate
16026 setuid or setgid bits that are inappropriate if fchown fails.
16027
16028 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16029
16030 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16031 to compare Lisp_Objects.
16032 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16033 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16034 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16035
16036 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16037
16038 * lread.c (read_integer): Unread even EOF character.
16039 (read1): Likewise. Properly record start position of symbol.
16040
16041 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16042 symbol character follows.
16043
16044 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16045
16046 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16047 This works around a problem with the previous change to Fcopy_file.
16048 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16049 and without this change, GCC might complain about discarding
16050 fchown's return value.
16051
16052 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16053
16054 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16055
16056 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16057
16058 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16059
16060 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16061
16062 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16063 it's used from the C level.
16064
16065 * process.c: Use the same condition for POLL_FOR_INPUT in both
16066 keyboard.c and process.c (bug#1858).
16067
16068 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16069
16070 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16071 (Fgnutls_boot): Use it.
16072
16073 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16074
16075 * doc.c (Fsubstitute_command_keys): Revert last change.
16076
16077 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16078
16079 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16080 quotes the next character, and doesn't affect other longer
16081 sequences (bug#8935).
16082
16083 * lread.c (syms_of_lread): Clarify that is isn't only
16084 `eval-buffer' and `eval-defun' that's affected by
16085 `lexical-binding' (bug#8460).
16086
16087 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16088
16089 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16090 bidi redisplay when a line includes both an image and is truncated.
16091
16092 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16093
16094 Fix minor problems found by static checking.
16095 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16096 (elsz): Now a signed constant, not a size_t var. We prefer signed
16097 types to unsigned, to avoid integer comparison confusion. Without
16098 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16099 "cannot optimize loop, the loop counter may overflow", a symptom
16100 of the confusion.
16101 * indent.c (Fvertical_motion): Mark locals as initialized.
16102 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16103
16104 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16105
16106 * search.c (Fre_search_backward): Mention `case-fold-search' in
16107 all the re_search_* functions (bug#8138).
16108
16109 * keyboard.c (Fopen_dribble_file): Document when the file is
16110 closed (bug#8056).
16111
16112 2011-07-14 Eli Zaretskii <eliz@gnu.org>
16113
16114 * bidi.c (bidi_dump_cached_states): Fix format of displaying
16115 bidi_cache_idx.
16116
16117 Support bidi reordering of display and overlay strings.
16118 * xdisp.c (compute_display_string_pos)
16119 (compute_display_string_end): Accept additional argument STRING.

16122 bidi_it->string.schars.
16123 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16124 NULL (avoids a crash in bidi_paragraph_init).
16125 Initialize itb.string.lstring.
16126 (init_iterator): Call bidi_init_it only of a valid
16127 buffer position was specified. Initialize paragraph_embedding to
16128 L2R.
16129 (reseat_to_string): Initialize the bidi iterator.
16130 (display_string): If we need to ignore text properties of
16131 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16132 original value of -1 will not work with bidi.)
16133 (compute_display_string_pos): First arg is now struct
16134 `text_pos *'; all callers changed. Support display properties on
16135 Lisp strings.
16136 (compute_display_string_end): Support display properties on Lisp
16137 strings.
16138 (init_iterator, reseat_1, reseat_to_string): Initialize the
16139 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16140 when iterating on a string not from display properties).
16141 (compute_display_string_pos, compute_display_string_end):
16142 Fix calculation of the object to scan. Fixes an error when using
16143 arrow keys.
16144 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16145 base_level_stop; instead, set base_level_stop to BEGV.
16146 Fixes crashes in vertical-motion.
16147 (next_element_from_buffer): Improve commentary for when
16148 the iterator is before prev_stop.
16149 (init_iterator): Initialize bidi_p from the default value of
16150 bidi-display-reordering, not from buffer-local value. Use the
16151 buffer-local value only if initializing for buffer iteration.
16152 (handle_invisible_prop): Support invisible properties on strings
16153 that are being bidi-reordered.
16154 (set_iterator_to_next): Support bidi reordering of C strings and

16164 (next_element_from_string, next_element_from_c_string)
16165 (next_element_from_buffer): Add xassert's for correspondence
16166 between IT's object being iterated and it->bidi_it.string
16167 structure.
16168 (face_before_or_after_it_pos): Support bidi iteration.
16169 (next_element_from_c_string): Handle the case of the first string
16170 character that is not the first one in the visual order.
16171 (get_visually_first_element): New function, refactored from common
16172 parts of next_element_from_buffer, next_element_from_string, and
16173 next_element_from_c_string.
16174 (tool_bar_lines_needed, redisplay_tool_bar)
16175 (display_menu_bar): Force left-to-right direction. Add a FIXME
16176 comment for making that be controlled by a user option.
16177 (push_it, pop_it): Save and restore the state of the
16178 bidi iterator. Save and restore the bidi_p flag.

16185 (get_overlay_strings_1, push_display_prop): Set up the bidi
16186 iterator for displaying display or overlay strings.
16187 (forward_to_next_line_start): Don't use the shortcut if
16188 bidi-iterating.
16189 (back_to_previous_visible_line_start): If handle_display_prop
16190 pushed the iterator stack, restore the internal state of the bidi
16191 iterator by calling bidi_pop_it same number of times.
16192 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16193 and we are bidi-iterating, don't decrement the iterator position;
16194 instead, set the first_elt flag in the bidi iterator, to produce
16195 the same effect.
16196 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16197 (push_display_prop): xassert that we are iterating a buffer.
16198 (push_it, pop_it): Save and restore paragraph_embedding member.

16209 (pop_it): Call iterate_out_of_display_property only if we are
16210 popping after iteration over a string that came from a display
16211 property. Fix a typo in popping stretch info. Add an assertion
16212 for verifying that the iterator position is in sync with the bidi
16213 iterator.
16214 (handle_single_display_spec, get_overlay_strings_1)
16215 (push_display_prop): Fix initialization of paragraph direction for
16216 string when that of the parent object is not yet determined.
16217 (reseat_1): Call bidi_init_it to resync the bidi
16218 iterator with IT's position. (Bug#7616)
16219 (find_row_edges): If ROW->start.pos gives position
16220 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
16221 (handle_stop, back_to_previous_visible_line_start, reseat_1):
16222 Reset the from_disp_prop_p flag.
16223 (SAVE_IT, RESTORE_IT): New macros.

16228 (try_scrolling, redisplay_window, display_line): Use them when
16229 saving a temporary copy of the iterator and restoring it back.
16230 (back_to_previous_visible_line_start, reseat_1)
16231 (init_iterator): Empty the bidi cache "stack".
16232 (move_it_in_display_line_to): If iterator ended up at
16233 EOL, but we never saw any buffer positions smaller than
16234 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16235 motion in bidi-reordered lines.
16236 (move_it_in_display_line_to): Record prev_method and prev_pos
16237 immediately before the call to set_iterator_to_next. Fixes cursor
16238 motion in bidi-reordered lines with stretch glyphs and strings
16239 displayed in margins. (Bug#8133) (Bug#8867)
16240 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16241 TO_CHARPOS.
16242 (pos_visible_p): Support positions in bidi-reordered lines.
16243 Save and restore bidi cache.
16244

16255 (bidi_move_to_visually_next): Compare cache index with
16256 bidi_cache_start rather than with zero.
16257 (bidi_fetch_char): Accept new argument STRING; all callers
16258 changed. Support iteration over a string. Support strings with
16259 display properties. Support unibyte strings. Fix the type of
16260 `len' according to what STRING_CHAR_AND_LENGTH expects.

16275 values.
16276 (bidi_level_of_next_char): Allow the sentinel "position" to pass
16277 the test for valid cached positions. Fix the logic for looking up
16278 the sentinel state in the cache. GCPRO the Lisp string we are
16279 iterating.
16280 (bidi_push_it, bidi_pop_it): New functions.
16281 (bidi_initialize): Initialize the bidi cache start stack pointer.
16282 (bidi_cache_ensure_space): New function, refactored from part of

16290 is valid if it's going to be used.
16291 (bidi_shelve_cache, bidi_unshelve_cache): New functions.
16292 (bidi_cache_fetch_state, bidi_cache_search)
16293 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16294 (bidi_cache_iterator_state, bidi_cache_find)
16295 (bidi_find_other_level_edge, bidi_cache_start_stack):
16296 All variables related to cache indices are now EMACS_INT.
16297
16298 * dispextern.h (struct bidi_string_data): New structure.
16299 (struct bidi_it): New member `string'. Make flag members be 1-bit

16347 * xselect.c (Qx_lost_selection_functions)
16348 (Qx_sent_selection_functions): New vars.
16349 (syms_of_xselect): DEFSYM them.
16350 (x_handle_selection_request): Pass Qx_sent_selection_functions
16351 rather than Vx_sent_selection_functions to Frun_hook_with_args.
16352 (x_handle_selection_clear,x_clear_frame_selections):
16353 Pass Qx_lost_selection_functions rather than

16357
16358 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16359 The old code sometimes used this field without initializing it.
16360
16361 * alloc.c (gc_sweep): Don't read past end of array.
16362 In theory, the old code could also have corrupted Emacs internals,
16363 though it'd be very unlikely.

16667 Random fixes. E.g., (random) never returned negative values.
16668 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16669 subseconds part to the entropy, as that's a bit more random.
16670 Prefer signed to unsigned, since the signedness doesn't matter and
16671 in general we prefer signed. When given a limit, use a
16672 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16673 latter isn't right if USE_2_TAGS_FOR_INTS.

16716
16717 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16718 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

16787
16788 * Makefile.in (SETTINGS_LIBS): Fix typo.
16789
16790 2011-07-01 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
16791
16792 * coding.c (Fencode_coding_string): Record the last coding system
16793 used, as the function doc string says (bug#8738).

16802 (emacs_settings_init, gsettings_obj): Remove.
16803 (something_changedCB): New function for HAVE_GSETTINGS.

16805 with value as argument.
16806 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
16807 g_settings_new (Bug#8967). Do not create gsettings_obj.

16819
16820 * eval.c (struct backtrace): Simplify and port the data structure.
16821 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16822 signed bit field, as this assumption is not portable and it makes
16823 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16824 "char debug_on_exit : 1" as this is not portable either; instead,
16825 use the portable "unsigned int debug_on_exit : 1". Remove unused
16826 member evalargs. Remove obsolete comments about cc bombing out.
16827

16863 clearly which files are directly included by each source file,
16864 and not through other includes.
16865
16866 2011-06-27 Martin Rudalics <rudalics@gmx.at>
16867
16868 * buffer.c (Qclone_number): Declare static and DEFSYM it.
16869 (sort_overlays, overlay_strings): When an overlay's clone number
16870 matches the window's clone number process the overlay even if
16871 the overlay's window property doesn't match the current window.

16909
16910 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
16911 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
16912 called at ZV.
16913
16914 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
16915
16916 * process.c (wait_reading_process_output): Bypass select if
16917 waiting for a cell while ignoring keyboard input, and input is
16918 pending. Suggested by Jan Djärv (Bug#8869).
16919

16993
16994 * print.c (printchar, strout): Check for string overflow.
16995 (PRINTPREPARE, printchar, strout):
16996 Don't set size unless allocation succeeds.
16997
16998 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16999 for sizes. Check for string overflow more accurately.

17012 * lread.c: Integer overflow fixes.
17013 (read_integer): Radix is now EMACS_INT, not int,
17014 to improve quality of diagnostics for out-of-range radices.
17015 Calculate buffer size correctly for out-of-range radices.
17016 (read1): Check for integer overflow in radices, and in
17017 read-circle numbers.
17018 (read_escape): Avoid int overflow.
17019 (Fload, openp, read_buffer_size, read1)
17020 (substitute_object_recurse, read_vector, read_list, map_obarray):
17021 Use ptrdiff_t, not int, for sizes.

17041 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17042
17043 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17044 The following patches are for when GLYPH_DEBUG && !XASSERT.
17045 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17046 * dispnew.c (flush_stdout):
17047 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17048 Mark as externally visible.
17049 * dispnew.c (check_window_matrix_pointers): Now static.

17059 Now static.
17060 (debug_method_add): Use va_list and vsprintf rather than relying
17061 on undefined behavior with wrong number of arguments.
17062 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17063 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17064 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17065 since we're not interested in debugging glyphs with old libraries.
17066 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17067 GCC 4.6.0's static checking.
17068
17069 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

17154 Reformulate so as not to need the command string.
17155 Invoke gzip -cd rather than gunzip, as it's more portable.
17156 (lock_info_type, lock_file_1, lock_file):
17157 Don't assume pid_t and time_t fit in unsigned long.

17179 We prefer signed integers, even for size calculations.
17180
17181 * emacs.c: Don't assume string length fits in 'int'.
17182 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17183 (main): Don't invoke strlen when not needed.
17184
17185 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17186 (XD_DEBUG_MESSAGE): Don't waste a byte.
17187
17188 * callproc.c (getenv_internal_1, getenv_internal)
17189 (Fgetenv_internal):
17190 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17191
17192 * lread.c (invalid_syntax): Omit length argument.
17193 All uses changed. This doesn't fix a bug, but it simplifies the
17194 code away from its former Hollerith-constant appearance, and it's
17195 one less 'int' to worry about when looking at integer-overflow issues.
17196 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17197
17198 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17199 This didn't break anything, but it didn't help either.
17200 It's confusing to put a bogus integer in a place where the actual
17201 value does not matter.
17202 (LIST_END_P): Remove unused macro and its bogus comment.
17203 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17204
17205 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17206 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17207 implementation.
17208 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17209 We prefer signed types, and the value cannot exceed the EMACS_INT
17210 range anyway (because otherwise the length would not be representable).
17211 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17212 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17213 This avoids a GCC warning when WIDE_EMACS_INT.
17214
17215 * indent.c (sane_tab_width): New function.
17216 (current_column, scan_for_column, Findent_to, position_indentation)
17217 (compute_motion): Use it. This is just for clarity.
17218 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17219
17220 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17221
17222 * lisp.h (lint_assume): New macro.
17223 * composite.c (composition_gstring_put_cache):
17224 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17225
17226 * editfns.c, insdel.c:
17227 Omit unnecessary forward decls, to simplify future changes.
17228
17229 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17230
17231 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17232
17233 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17234 Use much-faster test for byte-length change.
17235 Don't assume string byte-length fits in 'int'.
17236 Check that character arg fits in 'int'.
17237 (mapcar1): Declare byte as byte, for clarity.
17238
17239 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17240
17241 * fns.c (concat): Catch string overflow earlier.
17242 Do not rely on integer wraparound.
17243
17244 * dispextern.h (struct it.overlay_strings_charpos)
17245 (struct it.selective): Now EMACS_INT, not int.
17246 * xdisp.c (forward_to_next_line_start)
17247 (back_to_previous_visible_line_start)
17248 (reseat_at_next_visible_line_start, next_element_from_buffer):
17249 Don't arbitrarily truncate the value of 'selective' to int.
17250
17251 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17252
17253 * composite.c: Don't truncate sizes to 'int'.
17254 (composition_gstring_p, composition_reseat_it)
17255 (composition_adjust_point): Use EMACS_INT, not int.
17256 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17257 not EMACS_UINT, for indexes.
17258
17259 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17260
17261 * buffer.c: Include <verify.h>.
17262 (struct sortvec.priority, struct sortstr.priority):
17263 Now EMACS_INT, not int.
17264 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17265 (struct sortstr.size, record_overlay_string)
17266 (struct sortstrlist.size, struct sortlist.used):
17267 Don't truncate size to int.
17268 (record_overlay_string): Check for size-calculation overflow.
17269 (init_buffer_once): Check at compile-time, not run-time.
17270
17271 2011-06-22 Jim Meyering <meyering@redhat.com>
17272
17273 Don't leak an XBM-image-sized buffer
17274 * image.c (xbm_load): Free the image buffer after using it.
17275
17276 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17277
17278 Port to Sun C.
17279 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17280 that Sun C diagnosed.
17281 * fns.c (secure_hash): Fix pointer signedness issue.
17282 * intervals.c (static_offset_intervals): New function.
17283 (offset_intervals): Use it.
17284
17285 2011-06-21 Leo Liu <sdl.web@gmail.com>
17286
17287 * deps.mk (fns.o):
17288 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17289 sha512.h.
17290
17291 * fns.c (secure_hash): Rename from crypto_hash_function and change
17292 the first arg to accept symbols.
17293 (Fsecure_hash): New primitive.
17294 (syms_of_fns): New symbols.
17295
17296 2011-06-20 Deniz Dogan <deniz@dogan.se>
17297
17298 * process.c (Fset_process_buffer): Clarify return value in
17299 docstring.
17300
17301 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17302
17303 * dispnew.c (add_window_display_history): Use BVAR.
17304
17305 * xdisp.c (debug_method_add): Use BVAR.
17306 (check_window_end, dump_glyph_matrix, dump_glyph)
17307 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17308
17309 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17310 Likewise.
17311
17312 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17313 check till after the cache is created in init_frame_faces.
17314
17315 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17316
17317 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17318
17319 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17320
17321 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17322 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17323 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17324
17325 Improve buffer-overflow checking (Bug#8873).
17326 * fileio.c (Finsert_file_contents):
17327 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17328 Remove the old (too-loose) buffer overflow checks.
17329 They weren't needed, since make_gap checks for buffer overflow.
17330 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17331 The old code merely checked for Emacs fixnum overflow, and relied
17332 on undefined (wraparound) behavior. The new code avoids undefined
17333 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17334
17335 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17336 Tune. Don't use wider integers than needed. Don't use alloca.
17337 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17338
17339 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17340
17341 * insdel.c, lisp.h (buffer_overflow): New function.
17342 (insert_from_buffer_1, replace_range, replace_range_2):
17343 * insdel.c (make_gap_larger):
17344 * editfns.c (Finsert_char):
17345 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17346
17347 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17348
17349 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17350
17351 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17352
17353 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17354 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17355
17356 * fileio.c: Don't assume EMACS_INT fits in off_t.
17357 (emacs_lseek): New static function.
17358 (Finsert_file_contents, Fwrite_region): Use it.
17359 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17360
17361 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17362
17363 * fns.c: Don't overflow int when computing a list length.
17364 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17365 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17366 truncation on 64-bit hosts. Check for QUIT every
17367 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17368 faster and is responsive enough.
17369 (Flength): Report an error instead of overflowing an integer.
17370 (Fsafe_length): Return a float if the value is not representable
17371 as a fixnum. This shouldn't happen except in contrived situations.
17372 (Fnthcdr, Fsort): Don't assume list length fits in int.
17373 (Fcopy_sequence): Don't assume vector length fits in int.
17374
17375 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17376 (header_size, word_size): New constants.
17377 (allocate_vectorlike): Don't check size overflow here.
17378 (allocate_vector): Check it here instead, since this is the only
17379 caller of allocate_vectorlike that could cause overflow.
17380 Check that the new vector's length is representable as a fixnum.
17381
17382 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17383 The previous code was bogus. For example, next_almost_prime (32)
17384 returned 39, which is undesirable as it is a multiple of 3; and
17385 next_almost_prime (24) returned 25, which is a multiple of 5 so
17386 why was the code bothering to check for multiples of 7?
17387
17388 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17389
17390 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17391
17392 Variadic C functions now count arguments with ptrdiff_t.
17393 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17394 Back then I didn't know that the Emacs coding style prefers signed int.
17395 Also, in the meantime I found a few more instances where arguments
17396 were being counted with int, which may truncate counts on 64-bit
17397 machines, or EMACS_INT, which may be unnecessarily wide.
17398 * lisp.h (struct Lisp_Subr.function.aMANY)
17399 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17400 Arg counts are now ptrdiff_t, not size_t.
17401 All variadic functions and their callers changed accordingly.
17402 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17403 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17404 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17405 * callint.c (Fcall_interactively): Check arg count for overflow,
17406 to avoid potential buffer overrun. Use signed char, not 'int',
17407 for 'varies' array, so that we needn't bother to check its size
17408 calculation for overflow.
17409 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17410 * eval.c (apply_lambda):
17411 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17412 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17413 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17414
17415 * callint.c (Fcall_interactively): Don't use index var as event count.
17416
17417 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17418 * mem-limits.h (SIZE): Remove; no longer used.
17419
17420 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17421
17422 Remove unnecessary casts.
17423 * xterm.c (x_term_init):
17424 * xfns.c (x_set_border_pixel):
17425 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17426 These aren't needed now that we assume ANSI C.
17427
17428 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17429 It's more likely to cause problems (due to unsigned overflow)
17430 than to cure them.
17431
17432 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17433
17434 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17435
17436 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17437
17438 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17439
17440 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17441
17442 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17443
17444 GLYPH_CODE_FACE returns EMACS_INT, not int.
17445 * dispextern.h (merge_faces):
17446 * xfaces.c (merge_faces):
17447 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17448 Don't assume EMACS_INT fits in int.
17449
17450 * character.h (CHAR_VALID_P): Remove unused parameter.
17451 * fontset.c, lisp.h, xdisp.c: All uses changed.
17452
17453 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17454
17455 * fns.c (concat): Minor tuning based on overflow analysis.
17456 This doesn't fix any bugs. Use int to hold character, instead
17457 of constantly refetching from Emacs object. Use XFASTINT, not
17458 XINT, for value known to be a character. Don't bother comparing
17459 a single byte to 0400, as it's always less.
17460
17461 * floatfns.c (Fexpt):
17462 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17463
17464 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17465 for characters.
17466
17467 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17468
17469 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17470 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17471 incorrectly succeed when S was a string, because 4294967386 was
17472 truncated before it was used.
17473
17474 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17475 Otherwise, an out-of-range integer could cause undefined behavior
17476 on a 64-bit host.
17477
17478 * composite.c: Use int, not EMACS_INT, for characters.
17479 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17480 EMACS_INT, for values that are known to be in character range.
17481 This doesn't fix any bugs but is the usual style inside Emacs and
17482 may generate better code on 32-bit machines.
17483
17484 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17485 This is for reasons similar to the recent CHAR_STRING fix.
17486 * charset.c (Fencode_char): Check that character arg is actually
17487 a character. Pass an int to ENCODE_CHAR.
17488 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17489 wider than 'int', as a compile-time check to prevent future regressions
17490 in this area.
17491
17492 * character.c (char_string): Remove unnecessary casts.
17493
17494 Make sure a 64-bit char is never passed to CHAR_STRING.
17495 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17496 by silently ignoring the top 32 bits, allowing some values
17497 that were far too large to be valid characters.
17498 * character.h: Include <verify.h>.
17499 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17500 arguments are no wider than unsigned, as a compile-time check
17501 to prevent future regressions in this area.
17502 * data.c (Faset):
17503 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17504 (Fsubst_char_in_region):
17505 * fns.c (concat):
17506 * xdisp.c (decode_mode_spec_coding):
17507 Adjust to CHAR_STRING's new requirement.
17508 * editfns.c (Finsert_char, Fsubst_char_in_region):
17509 * fns.c (concat): Check that character args are actually
17510 characters. Without this test, these functions did the wrong
17511 thing with wildly out-of-range values on 64-bit hosts.
17512
17513 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17514 These casts should not be needed on 32-bit hosts, either.
17515 * keyboard.c (read_char):
17516 * lread.c (Fload): Remove casts to unsigned.
17517
17518 * lisp.h (UNSIGNED_CMP): New macro.
17519 This fixes comparison bugs on 64-bit hosts.
17520 (ASCII_CHAR_P): Use it.
17521 * casefiddle.c (casify_object):
17522 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17523 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17524 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17525 * dispextern.h (FACE_FROM_ID):
17526 * keyboard.c (read_char): Use UNSIGNED_CMP.
17527
17528 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17529 not to EMACS_INT, to avoid GCC warning.
17530
17531 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17532
17533 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17534 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17535 isn't needed on 32-bit machines.
17536
17537 * buffer.c (Fgenerate_new_buffer_name):
17538 Use EMACS_INT for count, not int.
17539 (advance_to_char_boundary): Return EMACS_INT, not int.
17540
17541 * data.c (Qcompiled_function): Now static.
17542
17543 * window.c (window_body_lines): Now static.
17544
17545 * image.c (gif_load): Rename local to avoid shadowing.
17546
17547 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17548 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17549 * alloc.c (make_save_value): Integer argument is now of type
17550 ptrdiff_t, not int.
17551 (mark_object): Use ptrdiff_t, not int.
17552 * lisp.h (pD): New macro.
17553 * print.c (print_object): Use it.
17554
17555 * alloc.c: Use EMACS_INT, not int, to count objects.
17556 (total_conses, total_markers, total_symbols, total_vector_size)
17557 (total_free_conses, total_free_markers, total_free_symbols)
17558 (total_free_floats, total_floats, total_free_intervals)
17559 (total_intervals, total_strings, total_free_strings):
17560 Now EMACS_INT, not int. All uses changed.
17561 (Fgarbage_collect): Compute overall total using a double, so that
17562 integer overflow is less likely to be a problem. Check for overflow
17563 when converting back to an integer.
17564 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17565 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17566 These were 'int' variables that could overflow on 64-bit hosts;
17567 they were never used, so remove them instead of repairing them.
17568 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17569 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17570 Previously, this ceilinged at INT_MAX, but that doesn't work on
17571 64-bit machines.
17572 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17573
17574 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.

18011 * editfns.c (Fformat):
18012 * eval.c (verror):
18013 Use STRING_BYTES_MAX, not MOST_POSITIVE_FIXNUM,
18014 since they may not be the same number.
18015 * editfns.c (Finsert_char):
18016 * fileio.c (Finsert_file_contents):
18017 Likewise for BUF_BYTES_MAX.
18018
18019 * image.c: Use ptrdiff_t, not int, for sizes.
18020 (slurp_file): Switch from int to ptrdiff_t.
18021 All uses changed.
18022 (slurp_file): Check that file size fits in both size_t (for
18023 malloc) and ptrdiff_t (for sanity and safety).
18024
18025 * fileio.c (Fverify_visited_file_modtime): Avoid time overflow
18026 if b->modtime has its maximal value.
18027
18028 * dired.c (Ffile_attributes): Don't assume EMACS_INT has >32 bits.
18029
18030 Don't assume time_t can fit into int.

18036 * character.h (MAYBE_UNIFY_CHAR):
18037 * charset.c (maybe_unify_char):
18038 * keyboard.c (read_char, reorder_modifiers):
18039 XINT -> XFASTINT, since the integer must be nonnegative.
18040 * ftfont.c (ftfont_spec_pattern):
18041 * keymap.c (access_keymap, silly_event_symbol_error):
18042 XUINT -> XFASTINT, since the integer must be nonnegative.
18043 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
18044 since it makes no difference and we prefer signed.
18045 * keyboard.c (record_char): Use XUINT when all the neighbors do.
18046 (access_keymap): NATNUMP -> INTEGERP, since the integer must be
18047 nonnegative.

18094
18095 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
18096
18097 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18098 Do not assume that spare memory exists; that assumption is valid
18099 only if SYSTEM_MALLOC.
18100 (LARGE_REQUEST): New macro, so that the issue of large requests
18101 is separated from the issue of spare memory.
18102

18161 display string.
18162 (bidi_paragraph_init, bidi_resolve_explicit_1)
18163 (bidi_level_of_next_char): Call bidi_fetch_char and
18164 bidi_fetch_char_advance instead of FETCH_CHAR and
18165 FETCH_CHAR_ADVANCE.
18166 (bidi_init_it): Initialize new members.
18167 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18168 definitions.
18169 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18170 instead of using explicit *_CHAR codes.
18171 (bidi_resolve_explicit, bidi_resolve_weak):
18172 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18173 bidirectional text is supported only in multibyte buffers.

18182 were just reseat()'ed to a new position.
18183
18184 * xdisp.c (set_cursor_from_row): Set start and stop points
18185 according to the row's direction when priming the loop that looks
18186 for the glyph on which to display cursor.
18187 (single_display_spec_intangible_p): Function deleted.
18188 (display_prop_intangible_p): Reimplement to call
18189 handle_display_spec instead of single_display_spec_intangible_p.
18190 Accept 3 additional arguments needed by handle_display_spec.
18191 This fixes incorrect cursor motion across display property with complex
18192 values: lists, `(when COND...)' forms, etc.
18193 (single_display_spec_string_p): Support property values that are
18194 lists with the argument STRING its top-level element.
18195 (display_prop_string_p): Fix the condition for processing a
18196 property that is a list to be consistent with handle_display_spec.
18197 (handle_display_spec): New function, refactored from the
18198 last portion of handle_display_prop.
18199 (compute_display_string_pos): Accept additional argument

18201 value of a `display' property is a "replacing spec".
18202 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18203 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

18205 the display property will replace the characters it covers.
18206 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18207 frame_window_p members of struct bidi_it.
18208 (compute_display_string_pos, compute_display_string_end):

18211 jump to continue iteration.
18212 (reseat_1): Initialize bidi_it.disp_pos.
18213
18214 * keyboard.c (adjust_point_for_property): Adjust the call to
18215 display_prop_intangible_p to its new signature.
18216
18217 * dispextern.h (struct bidi_it): New member frame_window_p.
18218 (bidi_init_it): Update prototypes.
18219 (display_prop_intangible_p): Update prototype.
18220 (compute_display_string_pos, compute_display_string_end):
18221 Declare prototypes.
18222 (struct bidi_it): New members nchars and disp_pos. ch_len is now

18229 * lisp.h: Change signatures accordingly.
18230 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18231 All callers changed. (Bug#8762)
18232
18233 * gnutls.c: Use Emacs's memory allocators.
18234 Without this change, the gnutls library would invoke malloc etc.
18235 directly, which causes problems on non-SYNC_INPUT hosts, and which
18236 runs afoul of improving memory_full behavior. (Bug#8761)
18237 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18238 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18239 xfree instead of the default malloc, realloc, free.
18240 (Fgnutls_boot): No need to check for memory allocation failure,
18241 since xmalloc does that for us.
18242
18243 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18244 * category.c (hash_get_category_set):

18251 * dispextern.h (struct image.hash):
18252 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
18253 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

18255 (maybe_resize_hash_table, hash_lookup, hash_put)
18256 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18257 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18258 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18259 * image.c (make_image, search_image_cache, lookup_image)
18260 (xpm_put_color_table_h):
18261 * lisp.h (struct Lisp_Hash_Table):
18262 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18263 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18264 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18265 * alloc.c (allocate_vectorlike):
18266 Check for overflow in vector size calculations.
18267 * ccl.c (ccl_driver):
18268 Check for overflow when converting EMACS_INT to int.
18269 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18270 need to be updated by these changes.
18271 * fns.c (make_hash_table, maybe_resize_hash_table):
18272 Check for integer overflow with large hash tables.
18273 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18274 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18275 (SXHASH_REDUCE): New macro.
18276 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18277 Use it instead of discarding useful hash info with large hash values.
18278 (sxhash_float): New function.
18279 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18280 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18281 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18282 Rewrite to use FIXNUM_BITS, as this simplifies things.
18283 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18284 Adjust signatures to match updated version of code.
18285 (consing_since_gc): Now EMACS_INT, since a single hash table can
18286 use more than INT_MAX bytes.

18363 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18364
18365 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18366
18367 * image.c: Various fixes to ImageMagick code comments.
18368 (Fimagemagick_types): Doc fix.
18369
18370 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18371
18372 Minor fixes prompted by GCC 4.6.0 warnings.
18373
18374 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18375
18376 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18377 (x_clipboard_manager_save_all): Move extern decl to ...
18378 * xterm.h: ... here, so that it can be checked for consistency.
18379
18380 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18381
18382 * xselect.c (x_clipboard_manager_save_frame)
18383 (x_clipboard_manager_save_all): New functions.
18384 (Fx_clipboard_manager_save): Lisp function deleted.
18385
18386 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18387 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18388
18389 * xterm.h: Update prototype.
18390
18391 2011-05-28 William Xu <william.xwl@gmail.com>
18392
18393 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18394 exiting (Bug#8239).
18395
18396 2011-05-28 Jim Meyering <meyering@redhat.com>
18397
18398 Avoid a sign-extension bug in crypto_hash_function.
18399 * fns.c (to_uchar): Define.
18400 (crypto_hash_function): Use it to convert some newly-signed
18401 variables to unsigned, to avoid sign-extension bugs. For example,
18402 without this change, (md5 "truc") would evaluate to
18403 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18404 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18405 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18406
18407 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18408
18409 Integer overflow fixes.
18410
18411 * dbusbind.c: Serial number integer overflow fixes.
18412 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18413 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18414 to hold a serial number that is too large for a fixnum.
18415 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18416 Check for serial numbers out of range. Decode any serial number
18417 that was so large that it became a float. (Bug#8722)
18418
18419 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18420 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18421 Use XFASTINT rather than XUINT when numbers are nonnegative.
18422 (xd_append_arg, Fdbus_method_return_internal):
18423 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18424 arguments, check that Lisp number is nonnegative, rather than
18425 silently wrapping negative numbers around. (Bug#8722)
18426 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18427 (Bug#8722)
18428
18429 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18430
18431 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18432
18433 ccl: Add integer overflow checks.
18434 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18435 (IN_INT_RANGE): New macros.
18436 (ccl_driver): Use them to check for integer overflow when
18437 decoding a CCL program. Many of the new checks are whether XINT (x)
18438 fits in int; it doesn't always, on 64-bit hosts. The new version
18439 doesn't catch all possible integer overflows, but it's an
18440 improvement. (Bug#8719)
18441
18442 * alloc.c (make_event_array): Use XINT, not XUINT.
18443 There's no need for unsigned here.
18444
18445 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18446 This follows up to the 2011-05-06 change that substituted uintptr_t
18447 for EMACS_INT. This case wasn't caught back then.
18448
18449 Rework Fformat to avoid integer overflow issues.
18450 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18451 now (part of C89). Include <verify.h>.
18452 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18453 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18454 (Fformat): Avoid the prepass trying to compute sizes; it was only
18455 approximate and thus did not catch overflow reliably. Instead, walk
18456 through the format just once, formatting and computing sizes as we go,
18457 checking for integer overflow at every step, and allocating a larger
18458 buffer as needed. Keep track separately whether the format is
18459 multibyte. Keep only the most-recently calculated precision, rather
18460 than them all. Record whether each argument has been converted to
18461 string. Use EMACS_INT, not int, for byte and char and arg counts.
18462 Support field widths and precisions larger than INT_MAX. Avoid
18463 sprintf's undefined behavior with conversion specifications such as %#d
18464 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18465 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18466 formatting out-of-range floating point numbers with int
18467 formats. (Bug#8668)
18468
18469 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18470
18471 * data.c: Avoid integer truncation in expressions involving floats.
18472 * data.c: Include <intprops.h>.
18473 (arith_driver): When there's an integer overflow in an expression
18474 involving floating point, convert the integers to floating point
18475 so that the resulting value does not suffer from catastrophic
18476 integer truncation. For example, on a 64-bit host (* 4
18477 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18478 Do not rely on undefined behavior after integer overflow.
18479
18480 merge count_size_as_multibyte, parse_str_to_multibyte
18481 * character.c, character.h (count_size_as_multibyte):
18482 Rename from parse_str_to_multibyte; all uses changed.
18483 Check for integer overflow.
18484 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18485 since it's now a duplicate of the other. This is more of
18486 a character than a buffer op, so better that it's in character.c.
18487 * fns.c, print.c: Adjust to above changes.
18488
18489 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18490
18491 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18492
18493 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18494
18495 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18496 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18497 (x_clipboard_manager_save): Now static.
18498 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18499
18500 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18501 (crypto_hash_function): Now static.
18502 Fix pointer signedness problems. Avoid unnecessary initializations.
18503
18504 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18505
18506 * termhooks.h (Vselection_alist): Make it terminal-local.
18507
18508 * terminal.c (create_terminal): Initialize it.
18509
18510 * xselect.c: Support for clipboard managers.
18511 (Vselection_alist): Move to termhooks.h as terminal-local var.
18512 (LOCAL_SELECTION): New macro.
18513 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18514 (symbol_to_x_atom): Remove gratuitous arg.
18515 (x_handle_selection_request, lisp_data_to_selection_data)
18516 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18517 (x_own_selection, x_get_local_selection, x_convert_selection):
18518 New arg, specifying work frame. Use terminal-local Vselection_alist.
18519 (some_frame_on_display): Delete unused function.
18520 (Fx_own_selection_internal, Fx_get_selection_internal)
18521 (Fx_disown_selection_internal, Fx_selection_owner_p)
18522 (Fx_selection_exists_p): New optional frame arg.
18523 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18524 (x_handle_selection_clear): Don't treat other terminals with the
18525 same keyboard specially. Use the terminal-local Vselection_alist.
18526 (x_clear_frame_selections): Use Frun_hook_with_args.
18527
18528 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18529
18530 * xterm.h: Add support for those atoms.
18531
18532 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18533
18534 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18535 (converted_selections, conversion_fail_tag): New global variables.
18536 (x_selection_request_lisp_error): Free the above.
18537 (x_get_local_selection): Remove unnecessary code.
18538 (x_reply_selection_request): Args changed; handle arbitrary array
18539 of converted selections stored in converted_selections.
18540 Separate the XChangeProperty and SelectionNotify steps.
18541 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18542 (x_convert_selection): New function.
18543 (x_handle_selection_event): Simplify.
18544 (x_get_foreign_selection): Don't ignore incoming requests while
18545 waiting for an answer; this will fail when we implement
18546 SAVE_TARGETS, and seems unnecessary anyway.
18547 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18548 (Vx_sent_selection_functions): Doc fix.
18549
18550 2011-05-26 Leo Liu <sdl.web@gmail.com>
18551
18552 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18553
18554 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18555
18556 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18557
18558 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18559 for fringe update if it has periodic bitmap.
18560 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18561 and fringe_bitmap_periodic_p.
18562
18563 * fringe.c (get_fringe_bitmap_data): New function.
18564 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18565 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18566 row. Mark glyph row for fringe update if periodicity changed.
18567
18568 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18569 for fringe update unless it has periodic bitmap.
18570
18571 2011-05-25 Kenichi Handa <handa@m17n.org>
18572
18573 * xdisp.c (get_next_display_element): Set correct it->face_id for
18574 a static composition.
18575
18576 2011-05-24 Leo Liu <sdl.web@gmail.com>
18577
18578 * deps.mk (fns.o):
18579 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18580
18581 * fns.c (crypto_hash_function, Fsha1): New function.
18582 (Fmd5): Use crypto_hash_function.
18583 (syms_of_fns): Add Ssha1.
18584
18585 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18586
18587 * gnutls.c: Remove unused macros.
18588 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18589 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18590 Remove macros that are defined and never used.
18591 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18592
18593 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18594
18595 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18596 (Fx_get_selection_internal): Minor cleanup.
18597 (Fx_own_selection_internal): Rename arguments for consistency with
18598 select.el.
18599
18600 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18601
18602 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18603
18604 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18605
18606 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18607
18608 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18609
18610 * dispnew.c (scrolling_window): Don't exclude the case that the
18611 last enabled row in the desired matrix touches the bottom boundary.
18612
18613 2011-05-21 Glenn Morris <rgm@gnu.org>
18614
18615 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18616 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18617 and add some more files.
18618
18619 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18620
18621 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18622 report_file_error introduced by the change from 2011-05-07.
18623
18624 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18625
18626 * systime.h (Time): Define only if emacs is defined.
18627 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18628 where the include path doesn't have X11/X.h by default. See
18629 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18630
18631 2011-05-20 Kenichi Handa <handa@m17n.org>
18632
18633 * composite.c (find_automatic_composition): Fix previous change.
18634
18635 2011-05-20 Glenn Morris <rgm@gnu.org>
18636
18637 * lisp.mk: New file, split from Makefile.in.
18638 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18639 (shortlisp): Remove.
18640 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18641
18642 2011-05-19 Glenn Morris <rgm@gnu.org>
18643
18644 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18645 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18646 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18647 (lisp): Set the order to that of loadup.el.
18648 (shortlisp): Make it a copy of $lisp.
18649 (SOME_MACHINE_LISP): Remove.
18650 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18651 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18652
18653 2011-05-18 Kenichi Handa <handa@m17n.org>
18654
18655 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18656 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18657 (find_automatic_composition): Mostly rewrite for efficiency.
18658
18659 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18660
18661 * makefile.w32-in: Update dependencies.
18662
18663 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18664
18665 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18666 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18667
18668 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18669
18670 Fix some integer overflow issues, such as string length overflow.
18671
18672 * insdel.c (count_size_as_multibyte): Check for string overflow.
18673
18674 * character.c (lisp_string_width): Check for string overflow.
18675 Use EMACS_INT, not int, for string indexes and lengths; in
18676 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18677 the resulting string length overflows an EMACS_INT; instead,
18678 report a string overflow if no precision given. When checking for
18679 precision exhaustion, use a check that cannot possibly have
18680 integer overflow. (Bug#8675)
18681 * character.h (lisp_string_width): Adjust to new signature.
18682
18683 * alloc.c (string_overflow): New function.
18684 (Fmake_string): Use it. This doesn't change behavior, but saves
18685 a few bytes and will simplify future changes.
18686 * character.c (string_escape_byte8): Likewise.
18687 * lisp.h (string_overflow): New decl.
18688
18689 Fixups, following up to the user-interface timestamp change.
18690 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18691 for UI timestamps, instead of unsigned long.
18692 * msdos.c (mouse_get_pos): Likewise.
18693 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18694 * w32gui.h (Time): Define by including "systime.h" rather than by
18695 declaring it ourselves. (Bug#8664)
18696
18697 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18698 * image.c (clear_image_cache): Likewise.
18699
18700 * term.c (term_mouse_position): Don't assume time_t wraparound.
18701
18702 Be more systematic about user-interface timestamps.
18703 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18704 and sometimes 'EMACS_UINT', to represent these timestamps.
18705 This change causes it to use 'Time' uniformly, as that's what X uses.
18706 This makes the code easier to follow, and makes it easier to catch
18707 integer overflow bugs such as Bug#8664.
18708 * frame.c (Fmouse_position, Fmouse_pixel_position):
18709 Use Time, not unsigned long, for user-interface timestamps.
18710 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18711 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18712 * keyboard.h (last_event_timestamp): Likewise.
18713 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18714 * menu.h (xmenu_show): Likewise.
18715 * term.c (term_mouse_position): Likewise.
18716 * termhooks.h (struct input_event.timestamp): Likewise.
18717 (struct terminal.mouse_position_hook): Likewise.
18718 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18719 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18720 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18721 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18722 what it was before.
18723 * menu.h, termhooks.h: Include "systime.h", for Time.
18724
18725 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18726 Don't assume that the difference between two unsigned long values
18727 can fit into an integer. At this point, we know button_down_time
18728 <= event->timestamp, so the difference must be nonnegative, so
18729 there's no need to cast the result if double-click-time is
18730 nonnegative, as it should be; check that it's nonnegative, just in
18731 case. This bug is triggered when events are more than 2**31 ms
18732 apart (about 25 days). (Bug#8664)
18733
18734 * xselect.c (last_event_timestamp): Remove duplicate decl.
18735 (x_own_selection): Remove needless cast to unsigned long.
18736
18737 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18738 that always fit in int. Use a sentinel instead of a counter, to
18739 avoid a temp and to allay GCC's concerns about possible int overflow.
18740 * frame.h (struct frame): Use int for menu_bar_items_used
18741 instead of EMACS_INT, since it always fits in int.
18742
18743 * menu.c (grow_menu_items): Check for int overflow.
18744
18745 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18746
18747 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18748 Before, the code was not consistent. These values cannot exceed
18749 2**31 - 1 so there's no need to make them unsigned.
18750 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18751 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18752 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18753 as modifiers.
18754 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18755
18756 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18757 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18758 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18759 presumably because the widths might not match.
18760
18761 * window.c (size_window): Avoid needless test at loop start.
18762
18763 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18764
18765 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18766
18767 2011-05-12 Drew Adams <drew.adams@oracle.com>
18768
18769 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18770
18771 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18772
18773 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18774 `width' to `bar_area_x' and `bar_area_width', respectively.
18775 (x_scroll_run): Take account of fringe background extension.
18776
18777 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18778 Rename local vars `left' and `width' to `bar_area_x' and
18779 `bar_area_width', respectively.
18780 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18781 background extension.
18782
18783 2011-05-10 Jim Meyering <meyering@redhat.com>
18784
18785 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18786
18787 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18788
18789 * image.c (Finit_image_library): Return t for built-in image types,
18790 like pbm and xbm. (Bug#8640)
18791
18792 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18793
18794 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18795
18796 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18797
18798 * w32console.c (Fset_screen_color): Doc fix.
18799 (Fget_screen_color): New function.
18800 (syms_of_ntterm): Defsubr it.
18801
18802 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18803 unlink the temporary file if Fcall_process didn't create it in the
18804 first place.
18805 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18806 child process will be redirected to a file specified with `:file'.
18807 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18808 cue to call_process_cleanup not to close that handle.
18809
18810 2011-05-07 Ben Key <bkey76@gmail.com>
18811
18812 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18813 one of two shell specific rules, either bootstrap-temacs-CMD or
18814 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18815 to the previous implementation of the bootstrap-temacs rule.
18816 The bootstrap-temacs-CMD rule is similar to the previous
18817 implementation of the bootstrap-temacs rule except that it
18818 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18819 variable.
18820
18821 These changes, along with some changes to nt/configure.bat,
18822 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18823 earlier fix to add support for --cflags and --ldflags options
18824 that include quotes so that it works whether make uses cmd or
18825 sh as the shell.
18826
18827 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18828
18829 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18830 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18831 is a constant.
18832 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18833 a string. Handle both cases.
18834 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18835 (Fdbus_register_method): Use Qinvalid_function.
18836
18837 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18838
18839 * makefile.w32-in: Update dependencies.
18840 (LISP_H): Add inttypes.h and stdin.h.
18841 (PROCESS_H): Add unistd.h.
18842
18843 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18844
18845 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18846 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18847
18848 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18849
18850 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18851
18852 * term.c (vfatal): Remove stray call to va_end.
18853 It's not needed and the C Standard doesn't allow it here anyway.
18854
18855 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18856 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18857
18858 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18859 bytes.
18860
18861 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18862
18863 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18864
18865 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18866
18867 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18868
18869 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18870
18871 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18872 * charset.c (Fdefine_charset_internal): Don't initialize
18873 charset.code_space[15]. The value was garbage, on hosts with
18874 32-bit int (Bug#8600).
18875
18876 * lread.c (read_integer): Be more consistent with string-to-number.
18877 Use string_to_number to do the actual conversion; this avoids
18878 rounding errors and fixes some other screwups. Without this fix,
18879 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18880 (digit_to_number): Move earlier, for benefit of read_integer.
18881 Return -1 if the digit is out of range for the base, -2 if it is
18882 not a digit in any supported base. (Bug#8602)
18883
18884 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18885
18886 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18887 to match comment at start of function. This also removes a
18888 GCC warning about overflow in a 32+64-bit port.
18889
18890 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18891
18892 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18893 Reported by Stefan Monnier in
18894 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18895 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18896 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18897
18898 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18899 (EMACS_UINTPTR): Likewise, with uintptr_t.
18900
18901 * lisp.h: Prefer 64-bit EMACS_INT if available.
18902 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18903 on 32-bit hosts that have 64-bit int, so that they can access
18904 large files.
18905 However, temporarily disable this change unless the temporary
18906 symbol WIDE_EMACS_INT is defined.
18907
18908 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18909
18910 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18911 This removes an assumption that EMACS_INT and long are the same
18912 width as pointers. The assumption is true for Emacs porting targets
18913 now, but we want to make other targets possible.
18914 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18915 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18916 In the rest of the code, change types of integers that hold casted
18917 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18918 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18919 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18920 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18921 No need to cast type when ORing.
18922 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18923 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18924 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18925 assume EMACS_INT is the same width as char *.
18926 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18927 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18928 Remove no-longer-needed casts.
18929 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18930 (xg_tool_bar_help_callback, xg_make_tool_item):
18931 Use EMACS_INTPTR to hold an integer
18932 that will be cast to void *; this can avoid a GCC warning
18933 if EMACS_INT is not the same width as void *.
18934 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18935 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18936 (current_message_1, set_message_1):
18937 Use a local to convert to proper width without a cast.
18938 * xmenu.c (dialog_selection_callback): Likewise.
18939
18940 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18941 Also, don't assume VALBITS / RAND_BITS is less than 5,
18942 and don't rely on undefined behavior when shifting a 1 left into
18943 the sign bit.
18944 * lisp.h (get_random): Change signature to match.
18945
18946 * lread.c (hash_string): Use size_t, not int, for hash computation.
18947 Normally we prefer signed values; but hashing is special, because
18948 it's better to use unsigned division on hash table sizes so that
18949 the remainder is nonnegative. Also, size_t is the natural width
18950 for hashing into memory. The previous code used 'int', which doesn't
18951 retain enough info to hash well into very large tables.
18952 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18953
18954 * dbusbind.c: Don't possibly lose pointer info when converting.
18955 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18956 Use XPNTR rather than XHASH, so that the high-order bits of
18957 the pointer aren't lost when converting through void *.
18958
18959 * eval.c (Fautoload): Don't double-shift a pointer.
18960
18961 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18962
18963 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18964
18965 * gnutls.c (DEF_GNUTLS_FN):
18966 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18967
18968 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18969
18970 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18971 marker. (Bug#8610)
18972
18973 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18974

18986
18987 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18988
18989 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):

18993
18994 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18995 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18996 Remove unused parameter `fildes'.
18997 * process.c (read_process_output, send_process): Don't pass it.
18998
18999 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19000
19001 Fix previous change: the library cache is defined in w32.c.
19002 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19003 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19004
19005 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19006
19007 Implement dynamic loading of GnuTLS on Windows.
19008
19009 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19010 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19011 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19012 Declare.
19013
19014 * gnutls.c (Qgnutls_dll): Define.
19015 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19016 (gnutls_*): Declare function pointers.
19017 (init_gnutls_functions): New function to initialize function pointers.
19018 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19019 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19020 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19021 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.

19023 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19024 (Fgnutls_available_p): New function.

19032 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19033 (w32_delayed_load): Move to w32.c.
19034
19035 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19036
19037 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19038 (w32_delayed_load): Move from image.c. When loading a library, record
19039 its filename in the :loaded-from property of the library id.
19040 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19041 Initialize and staticpro them.
19042 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19043
19044 * process.c: Include lisp.h before w32.h, not after.

19049
19050 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19051
19052 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

19060
19061 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19062
19063 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19064
19065 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19066
19067 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19068 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
19069 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)
19070 (gnutls_global_initialized, Qgnutls_bootprop_priority)
19071 (Qgnutls_bootprop_trustfiles, Qgnutls_bootprop_keyfiles)
19072 (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel)
19073 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
19074 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
19075 (Qgnutls_bootprop_callbacks_verify): Make static.
19076
19077 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
19078
19079 * callproc.c: Indentation fixup.
19080
19081 * sysdep.c (wait_for_termination_1): Make static.
19082 (wait_for_termination, interruptible_wait_for_termination):
19083 Move after wait_for_termination_1.
19084
19085 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19086
19087 * sysdep.c (interruptible_wait_for_termination): New function
19088 which is like wait_for_termination, but allows keyboard
19089 interruptions.
19090
19091 * callproc.c (Fcall_process): Add (:file "file") as an option for
19092 the STDOUT buffer.
19093 (Fcall_process_region): Ditto.
19094
19095 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19096
19097 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19098 rather than `XVECTOR (FOO)->size'.
19099
19100 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19101 inttypes.h, as a gnulib replacement is used if it not available in
19102 system headers.
19103
19104 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19105
19106 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19107 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19108 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19109
19110 * coding.c (coding_alloc_by_realloc): Error out if destination
19111 will grow beyond MOST_POSITIVE_FIXNUM.
19112 (decode_coding_emacs_mule): Abort if there isn't enough place in
19113 charbuf for the composition carryover bytes. Reserve an extra
19114 space for up to 2 characters produced in a loop.
19115 (decode_coding_iso_2022): Abort if there isn't enough place in
19116 charbuf for the composition carryover bytes.
19117
19118 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19119
19120 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19121 aborting when %lld or %lll format is passed.
19122 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19123 %llo or %llx format is passed. (Bug#8545)
19124
19125 * window.c (window_scroll_line_based): Use a marker instead of
19126 simple variables to record original value of point. (Bug#7952)
19127
19128 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19129 produced by %s or %c overflows available buffer space. (Bug#8545)
19130
19131 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19132
19133 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19134 (SIZE_MAX): Move defn after all includes, as they might #define it.
19135
19136 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19137
19138 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19139
19140 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19141
19142 * keyboard.c (Qdelayed_warnings_hook): Define.
19143 (command_loop_1): Run `delayed-warnings-hook'
19144 if Vdelayed_warnings_list is non-nil.
19145 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19146 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19147
19148 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19149
19150 * doprnt.c (doprnt): Don't return value smaller than the buffer
19151 size if the message was truncated. (Bug#8545).
19152
19153 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19154
19155 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19156 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19157
19158 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19159
19160 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19161
19162 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19163
19164 * makefile.w32-in: Update dependencies.
19165
19166 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19167
19168 Improve `doprnt' and its usage. (Bug#8545)
19169 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19170 `format_end'. Remove support for %l as a conversion specifier.
19171 Don't use xrealloc. Improve diagnostics when the %l size modifier
19172 is used. Update the commentary.
19173
19174 * eval.c (verror): Simplify calculation of size_t.
19175
19176 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19177 messages.
19178
19179 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19180
19181 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19182 change.
19183
19184 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19185
19186 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19187 This makes this file independent of the recent pseudovector change.
19188
19189 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19190
19191 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19192
19193 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19194 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19195 Remove unused local.
19196 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19197
19198 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19199 GCC 4.6.0 optimizes based on type-based alias analysis.
19200 For example, if b is of type struct buffer * and v of type struct
19201 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19202 != &v->size, and therefore "v->size = 1; b->size = 2; return
19203 v->size;" must therefore return 1. This assumption is incorrect
19204 for Emacs, since it type-puns struct Lisp_Vector * with many other
19205 types. To fix this problem, this patch adds a new type struct
19206 vectorlike_header that documents the constraints on layout of vectors
19207 and pseudovectors, and helps optimizing compilers not get fooled
19208 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19209 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19210 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19211 the size member.
19212 (XSETPVECTYPE): Rewrite in terms of new macro.
19213 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19214 This is a bit clearer, and further avoids the possibility of
19215 undesirable aliasing.
19216 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19217 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19218 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19219 since Lisp_Subr is a special case (no "next" field).
19220 (ASIZE): Now uses header.size rather than size.
19221 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19222 to avoid the hassle of writing XVECTOR (foo)->header.size.
19223 (struct vectorlike_header): New type.
19224 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19225 object, to help avoid aliasing.
19226 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19227 (SUBRP): Likewise, since Lisp_Subr is a special case.
19228 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19229 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19230 (struct Lisp_Hash_Table): Combine first two members into a single
19231 struct vectorlike_header member. All uses of "size" and "next" members
19232 changed to be "header.size" and "header.next".
19233 * buffer.h (struct buffer): Likewise.
19234 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19235 * frame.h (struct frame): Likewise.
19236 * process.h (struct Lisp_Process): Likewise.
19237 * termhooks.h (struct terminal): Likewise.
19238 * window.c (struct save_window_data, struct saved_window): Likewise.
19239 * window.h (struct window): Likewise.
19240 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19241 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19242 * buffer.c (init_buffer_once): Likewise.
19243 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19244 special case.
19245 * process.c (Fformat_network_address): Use local var for size,
19246 for brevity.
19247
19248 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19249
19250 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19251 * data.c (atof): Remove decl; no longer used or needed.
19252 (digit_to_number): Move to lread.c.
19253 (Fstring_to_number): Use new string_to_number function, to be
19254 consistent with how the Lisp reader treats infinities and NaNs.
19255 Do not assume that floating-point numbers represent EMACS_INT
19256 without losing information; this is not true on most 64-bit hosts.
19257 Avoid double-rounding errors, by insisting on integers when
19258 parsing non-base-10 numbers, as the documentation specifies.
19259 * lisp.h (string_to_number): New decl, replacing ...
19260 (isfloat_string): Remove.
19261 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19262 (read1): Do not accept +. and -. as integers; this
19263 appears to have been a coding error. Similarly, do not accept
19264 strings like +-1e0 as floating point numbers. Do not report
19265 overflow for integer overflows unless the base is not 10 which
19266 means we have no simple and reliable way to continue.
19267 Break out the floating-point parsing into a new
19268 function string_to_number, so that Fstring_to_number parses
19269 floating point numbers consistently with the Lisp reader.
19270 (digit_to_number): Move here from data.c. Make it static inline.
19271 (E_CHAR, EXP_INT): Remove, replacing with ...
19272 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19273 (string_to_number): New function, replacing isfloat_string.
19274 This function checks for valid syntax and produces the resulting
19275 Lisp float number too. Rework it so that string-to-number
19276 no longer mishandles examples like "1.0e+". Use strtoumax,
19277 so that overflow for non-base-10 numbers is reported only when
19278 there's no portable and simple way to convert to floating point.
19279
19280 * textprop.c (set_text_properties_1): Rewrite for clarity,
19281 and to avoid GCC warning about integer overflow.
19282
19283 * intervals.h (struct interval): Use EMACS_INT for members
19284 where EMACS_UINT might cause problems. See
19285 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19286 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19287 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19288 All uses changed.
19289 (offset_intervals): Tell GCC not to worry about length overflow
19290 when negating a negative length.
19291
19292 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19293 (overrun_check_free): Likewise.
19294
19295 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19296 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19297 word size.
19298
19299 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19300 (gnutls_make_error): Rename local to avoid shadowing.
19301 (gnutls_emacs_global_deinit): ifdef out; not used.
19302 (Fgnutls_boot): Use const for pointer to readonly storage.
19303 Comment out unused local. Fix pointer signedness problems.
19304
19305 * lread.c (openp): Don't stuff size_t into an 'int'.
19306 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19307 about possible signed overflow.
19308
19309 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19310 (GDK_KEY_g): Don't define if already defined.
19311 (xg_prepare_tooltip): Avoid pointer signedness problem.
19312 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19313
19314 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19315 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19316
19317 * xfns.c (Fx_window_property): Simplify a bit,
19318 to make a bit faster and to avoid GCC 4.6.0 warning.
19319 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19320
19321 * fns.c (internal_equal): Don't assume size_t fits in int.
19322
19323 * alloc.c (compact_small_strings): Tighten assertion a little.
19324
19325 Replace pEd with more-general pI, and fix some printf arg casts.
19326 * lisp.h (pI): New macro, generalizing old pEd macro to other
19327 conversion specifiers. For example, use "...%"pI"d..." rather
19328 than "...%"pEd"...".
19329 (pEd): Remove. All uses replaced with similar uses of pI.
19330 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19331 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19332 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19333 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19334 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19335 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19336 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19337 64-bit hosts.
19338 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19339 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19340 * print.c (safe_debug_print, print_object): Likewise.
19341 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19342 to int.
19343 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19344 avoiding the 0 flag, which is not portable.
19345 * process.c (Fmake_network_process): Use pI to avoid cast.
19346 * region-cache.c (pp_cache): Likewise.
19347 * xdisp.c (decode_mode_spec): Likewise.
19348 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19349 behavior on 64-bit hosts with printf arg.
19350 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19351 (x_stop_queuing_selection_requests): Likewise.
19352 (x_get_window_property): Don't truncate byte count to an 'int'
19353 when tracing.
19354
19355 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19356 here, since it parses constructs like leading '-' and spaces,
19357 which are not wanted; and it overflows with large numbers.
19358 Instead, simply match F[0-9]+, which is what is wanted anyway.
19359
19360 * alloc.c: Remove unportable assumptions about struct layout.
19361 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19362 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19363 (allocate_vectorlike, make_pure_vector): Use the new macros,
19364 plus offsetof, to remove unportable assumptions about struct layout.
19365 These assumptions hold on all porting targets that I know of, but
19366 they are not guaranteed, they're easy to remove, and removing them
19367 makes further changes easier.
19368
19369 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19370 This doesn't fix a bug but makes the code clearer.
19371 (string_overrun_cookie): Now const. Use initializers that
19372 don't formally overflow signed char, to avoid warnings.
19373 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19374 can cause Emacs to crash when string overrun checking is enabled.
19375 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19376 multiple of sizeof (EMACS_INT); it need not be, if
19377 alignof(EMACS_INT) < sizeof (EMACS_INT).
19378 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19379
19380 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
19381
19382 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
19383
19384 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19385
19386 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19387 supposed to be handshaking. (Bug#8556)
19388 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19389
19390 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19391
19392 * lisp.h (Qdebug): List symbol.
19393 * eval.c (Qdebug): Restore global linkage.
19394 * keyboard.c (debug-on-event): New variable.
19395 (handle_user_signal): Break into debugger when debug-on-event
19396 matches the current signal symbol.
19397
19398 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19399
19400 * alloc.c (check_sblock, check_string_bytes)
19401 (check_string_free_list): Convert to standard C.
19402
19403 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19404
19405 * w32.c (emacs_gnutls_push): Fix typo.
19406
19407 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19408
19409 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19410 "cast to pointer from integer of different size".
19411
19412 Improve doprnt and its use in verror. (Bug#8545)
19413 * doprnt.c (doprnt): Document the set of format control sequences
19414 supported by the function. Use SAFE_ALLOCA instead of always
19415 using `alloca'.
19416
19417 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19418 is one byte too soon. Don't use xrealloc; instead xfree and
19419 xmalloc anew.
19420
19421 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19422
19423 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19424 callbacks stage.
19425
19426 * gnutls.c: Renamed global_initialized to
19427 gnutls_global_initialized. Added internals for the
19428 :verify-hostname-error, :verify-error, and :verify-flags
19429 parameters of `gnutls-boot' and documented those parameters in the
19430 docstring. Start callback support.
19431 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19432 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19433 on error. Return error code.
19434 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19435 (emacs_gnutls_read): Likewise.
19436 (Fgnutls_boot): Return handshake error code.
19437 (emacs_gnutls_handle_error): New function.
19438 (wsaerror_to_errno): Likewise.
19439
19440 * w32.h (emacs_gnutls_pull): Add prototype.
19441 (emacs_gnutls_push): Likewise.
19442
19443 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
19444 (emacs_gnutls_push): Likewise.
19445
19446 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
19447
19448 * process.c (wait_reading_process_output): Check if GnuTLS
19449 buffered some data internally if no FDs are set for TLS
19450 connections.
19451
19452 * makefile.w32-in (OBJ2): Add gnutls.$(O).
19453 (LIBS): Link to USER_LIBS.
19454 ($(BLD)/gnutls.$(0)): New target.
19455
19456 2011-04-24 Eli Zaretskii <eliz@gnu.org>
19457
19458 * xdisp.c (handle_single_display_spec): Rename the
19459 display_replaced_before_p argument into display_replaced_p, to
19460 make it consistent with the commentary. Fix typos in the
19461 commentary.
19462
19463 * textprop.c (syms_of_textprop): Remove dead code.
19464 (copy_text_properties): Delete obsolete commentary about an
19465 interface that was deleted long ago. Fix typos in the description
19466 of arguments.
19467
19468 * msdos.c (XMenuActivate, XMenuAddSelection): Adjust argument list
19469 to changes in oldXMenu/XMenu.h from 2011-04-16.
19470 <menu_help_message, prev_menu_help_message>: Constify.
19471 (IT_menu_make_room): menu->help_text is now `const char **';
19472 adjust.
19473
19474 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
19475 to changes in oldXMenu/XMenu.h from 2011-04-16.
19476 (struct XMenu): Declare `help_text' `const char **'.
19477
19478 * xfaces.c <Qunspecified>: Make extern again.
19479
19480 * syntax.c: Include sys/types.h before including regex.h, as
19481 required by POSIX.
19482
19483 * doc.c (get_doc_string): Improve the format passed to `error'.
19484
19485 * doprnt.c (doprnt): Improve commentary.
19486
19487 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
19488
19489 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
19490 them with etags.
19491
19492 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
19493 changes in globals.h immediately force recompilation.
19494 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19495 $(CURDIR)/s/ms-w32.h.
19496 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
19497
19498 * character.c (Fchar_direction): Function deleted.
19499 (syms_of_character): Don't defsubr it.
19500 <char-direction-table>: Deleted.
19501
19502 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19503
19504 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19505 * doprnt.c: Include limits.h.
19506 (SIZE_MAX): New macro.
19507 (doprnt): Return a size_t value. 2nd arg is now size_t.
19508 Many local variables are now size_t instead of int or unsigned.
19509 Improve overflow protection. Support `l' modifier for integer
19510 conversions. Support %l conversion. Don't assume an EMACS_INT
19511 argument for integer conversions and for %c.
19512
19513 * lisp.h (doprnt): Restore prototype.
19514
19515 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

19736
19737 * nsfont.m: Fixed bugs in ns_get_family and
19738 ns_descriptor_to_entity that were caused by using free to
19739 deallocate memory blocks that were allocated by xmalloc (via

19741 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19742 --enable-checking=xmallocoverrun). xfree is now used to
19743 deallocate these memory blocks.

19961 * xfaces.c (face_at_string_position):
19962 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,

19987 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
19988 worth the hassle of breaking this out.

20103 * atimer.h (run_all_atimers): Remove; not exported.
20104
20105 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.

20107 was inaccessible from Lisp.

20146
20147 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20148
20149 Make Emacs functions such as Fatom 'static' by default.
20150 This makes it easier for human readers (and static analyzers)
20151 to see whether these functions can be called from other modules.
20152 DEFUN now defines a static function. To make the function external
20153 so that it can be used in other C modules, use the new macro DEFUE.
20154 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20155 (Finit_image_library):
20156 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

20159 Remove decls, since these functions are now static.
20160 (Funintern, Fget_internal_run_time): New decls, since these functions
20161 were already external.
20162
20163 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

20209 change. (Bug#8496)
20210
20211 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20212
20213 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20214 when at ZV. (Bug#8487)
20215
20216 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20217
20218 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20228
20229 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20230
20231 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20232 since callers should never pass a negative size.
20233 Change the signature to match that of plain 'read' and 'write'; see
20234 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20235 * lisp.h: Update prototypes of emacs_write and emacs_read.
20236
20237 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20238
20239 * xdisp.c (redisplay_window): Don't try to determine the character
20240 position of the scroll margin if the window start point w->startp
20241 is outside the buffer's accessible region. (Bug#8468)
20242
20243 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20244
20245 Fix write-region and its subroutines for buffers > 2GB.
20246 * fileio.c (a_write, e_write): Modify declaration of arguments and
20247 local variables to support buffers larger than 2GB.
20248 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20249
20250 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20251 argument, local variables, and return value.
20252
20253 * lisp.h: Update prototypes of emacs_write and emacs_read.
20254
20255 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20256
20257 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20258
20259 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20260
20261 Fix more problems found by GCC 4.6.0's static checks.
20262
20263 * xdisp.c (vmessage): Use a better test for character truncation.
20264
20265 * charset.c (load_charset_map): <, not <=, for optimization,
20266 and to avoid potential problems with integer overflow.
20267 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20268 * casetab.c (set_identity, shuffle): Likewise.
20269 * editfns.c (Fformat): Likewise.
20270 * syntax.c (skip_chars): Likewise.
20271
20272 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20273 This also lets GCC 4.6.0 generate slightly better loop code.
20274
20275 * callint.c (Fcall_interactively): <, not <=, for optimization.
20276 (Fcall_interactively): Count the number of arguments produced,
20277 not the number of arguments given. This is simpler and lets GCC
20278 4.6.0 generate slightly better code.
20279
20280 * ftfont.c: Distingish more carefully between FcChar8 and char.
20281 The previous code passed unsigned char * to a functions like
20282 strlen and xstrcasecmp that expect char *, which does not
20283 conform to the C standard.
20284 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20285 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20286 char * when the C standard requires it.
20287
20288 * keyboard.c (read_char): Remove unused var.
20289
20290 * eval.c: Port to Windows vsnprintf (Bug#8435).
20291 Include <limits.h>.
20292 (SIZE_MAX): Define if the headers do not.
20293 (verror): Do not give up if vsnprintf returns a negative count.
20294 Instead, grow the buffer. This ports to Windows vsnprintf, which
20295 does not conform to C99. Problem reported by Eli Zaretskii.
20296 Also, simplify the allocation scheme, by avoiding the need for
20297 calling realloc, and removing the ALLOCATED variable.
20298
20299 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20300
20301 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20302 But keep the doprint source code for now, as we might revamp it
20303 and use it again (Bug#8435).
20304 * lisp.h (doprnt): Remove.
20305 * Makefile.in (base_obj): Remove doprnt.o.
20306 * deps.mk (doprnt.o): Remove.
20307
20308 error: Print 32- and 64-bit integers portably (Bug#8435).
20309 Without this change, on typical 64-bit hosts error ("...%d...", N)
20310 was used to print both 32- and 64-bit integers N, which relied on
20311 undefined behavior.
20312 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20313 * lisp.h (error, verror): Mark as printf-like functions.
20314 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20315 Report overflow in size calculations when allocating printf buffer.
20316 Do not truncate output string at its first null byte.
20317 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20318 Truncate the output at a character boundary, since vsnprintf does not
20319 do that.
20320 * charset.c (check_iso_charset_parameter): Convert internal
20321 character to string before calling 'error', since %c now has the
20322 printf meaning.
20323 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20324 overflow when computing char to be passed to 'error'. Do not
20325 pass Lisp_Object to 'error'; pass the integer instead.
20326 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20327 formatted with plain %d.
20328
20329 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20330
20331 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20332
20333 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20334
20335 * xterm.c (x_catch_errors): Remove duplicate declaration.
20336
20337 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20338
20339 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20340
20341 2011-04-10 Jim Meyering <meyering@redhat.com>
20342
20343 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20344 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20345 return ssize_t not "int", and use size_t as the buffer length.
20346 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20347 * gnutls.h: Update declarations.
20348 * process.c (read_process_output): Use ssize_t, to match.
20349 (send_process): Likewise.
20350

20358 Use unsigned char, to match FcChar8 type definition.
20359
20360 * xterm.c (handle_one_xevent):
20361 * xmenu.c (create_and_show_popup_menu):
20362 * xselect.c (x_decline_selection_request)
20363 (x_reply_selection_request): Avoid type-punned deref of X events.
20364
20365 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20366
20367 Fix some uses of `int' instead of EMACS_INT.
20368 * search.c (string_match_1, fast_string_match)
20369 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20370 (scan_buffer, find_next_newline_no_quit)
20371 (find_before_next_newline, search_command, Freplace_match)
20372 (Fmatch_data): Make some `int' variables be EMACS_INT.
20373
20374 * xdisp.c (display_count_lines): 3rd argument and return value now
20375 EMACS_INT. All callers changed.

20391 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20392 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20393 Declare EMACS_INT.
20394 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.

20408 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20409
20410 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20411
20412 * process.c (Fformat_network_address): Doc fix.
20413
20414 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20415
20416 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20417
20418 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20419
20420 * keyboard.c (read_char): Call Lisp function help-form-show,
20421 instead of using internal_with_output_to_temp_buffer.
20422 (Qhelp_form_show): New var.
20423 (syms_of_keyboard): Use DEFSYM macro.
20424
20425 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20426
20427 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20428

20430
20431 * process.c (Flist_processes): Remove to Lisp.
20432 (list_processes_1): Delete.
20433
20434 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20435
20436 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20437
20438 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20439
20440 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20441
20442 Fix more problems found by GCC 4.6.0's static checks.
20443
20444 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20445
20446 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20447
20448 * lisp.h (message, message_nolog, fatal): Mark as printf-like.

20459 to system-supplied API.
20460
20461 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20462
20463 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20464 This avoids several warnings with gcc -Wstrict-overflow.
20465 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20466 directly, rather than having caller test rule sign. This avoids
20467 some unnecessary tests.
20468 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20469 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20470 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20471

20484 by using the new macro.
20485
20486 * textprop.c (set_text_properties_1): Change while to do-while,
20487 since the condition is always true at first.
20488
20489 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20490 (interval_deletion_adjustment): Return unsigned value.
20491 All uses changed.
20492

20507 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20508
20509 * print.c (print_error_message): Avoid int overflow.
20510
20511 * font.c (font_list_entities): Redo for clarity,
20512 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20513
20514 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20515 (font_score): Avoid potential overflow in diff calculation.
20516
20517 * fns.c (substring_both): Remove var that is set but not used.
20518 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20519
20520 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20521
20522 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20523 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20524 can always succeed if overflow has undefined behavior.
20525
20526 * search.c (boyer_moore, wordify): Remove vars set but not used.
20527 (wordify): Omit three unnecessary tests.
20528
20529 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

20533
20534 * dired.c (file_name_completion): Remove var that is set but not used.

20539 (Finsert_file_contents): Remove unnecessary code checking fd.
20540
20541 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20542 Check for integer overflow on size calculations.
20543
20544 * buffer.c (Fprevious_overlay_change): Remove var that is set
20545 but not used.
20546

20558 that are set but not used.
20559
20560 * xfns.c (make_invisible_cursor): Don't return garbage
20561 if XCreateBitmapFromData fails (Bug#8410).

20570 Remove var that is set but not used.
20571 (scroll_bar_windows_size): Now size_t, not int.
20572 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20573 Check for overflow.
20574

20581 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20582 All callers changed.

20590 * print.c (print_object): Remove var that is set but not used.
20591
20592 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20593 The gnulib version avoids calling malloc in the usual case,
20594 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20595 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20596 * filelock.c (current_lock_owner): Likewise.
20597 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

20699 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20700
20701 * xdisp.c (redisplay_internal): Fix prototype.
20702
20703 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20704
20705 * xdisp.c (SCROLL_LIMIT): New macro.
20706 (try_scrolling): Use it when setting scroll_limit.
20707 Limit scrolling to 100 screen lines.
20708 (redisplay_window): Even when falling back on "recentering",
20709 position point in the window according to scroll-conservatively,
20710 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20711
20712 (try_scrolling): When point is above the window, allow searching
20713 as far as scroll_max, or one screenful, to compute vertical
20714 distance from PT to the scroll margin position. This prevents
20715 try_scrolling from unnecessarily failing when
20716 scroll-conservatively is set to a value slightly larger than the
20717 window height. Clean up the case of PT below the margin at bottom
20718 of window: scroll_max can no longer be INT_MAX. When aggressive
20719 scrolling is in use, don't let point enter the opposite scroll
20720 margin as result of the scroll.
20721 (syms_of_xdisp) <scroll-conservatively>: Document the
20722 threshold of 100 lines for never-recentering scrolling.
20723
20724 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20725
20726 * dispextern.h (move_it_by_lines):
20727 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20728 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20729 (message_log_check_duplicate): Remove parameters `prev_bol' and
20730 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20731 (redisplay_internal): Remove parameter `preserve_echo_area',
20732 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20733
20734 * indent.c (Fvertical_motion):
20735 * window.c (window_scroll_pixel_based, Frecenter):
20736 Don't pass `need_y_p' to `move_it_by_lines'.
20737
20738 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20739
20740 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20741 steal a few bits to be more compact.
20742 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20743 Remove unneeded casts.
20744
20745 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20746
20747 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20748
20749 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20750 binding" message (bug#7967).
20751
20752 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20753
20754 Fix more problems found by GCC 4.6.0's static checks.
20755
20756 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20757 Remove unused local var.
20758
20759 * editfns.c (Fmessage_box): Remove unused local var.
20760
20761 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20762 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20763 Omit unused local vars.
20764 * window.c (shrink_windows): Omit unused local var.
20765 * menu.c (digest_single_submenu): Omit unused local var.
20766 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20767 Omit unused local var.
20768
20769 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20770 Don't assume string length fits in int.
20771 (keyremap_step, read_key_sequence): Use size_t for sizes.
20772 (read_key_sequence): Don't check last_real_key_start redundantly.
20773
20774 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20775 instead of alloca (Bug#8344).
20776
20777 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20778 (Fbacktrace_frame): Don't assume nframes fits in int.
20779
20780 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20781
20782 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20783 concerns.
20784
20785 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20786
20787 * cm.c (calccost): Turn while-do into do-while, for clarity.
20788
20789 * keyboard.c (syms_of_keyboard): Use the same style as later
20790 in this function when indexing through an array. This also
20791 works around GCC bug 48267.
20792
20793 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20794
20795 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20796
20797 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20798 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20799
20800 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20801 This avoids undefined behavior on integer overflow, and is a bit
20802 more convenient anyway since it is compared to a size_t variable.
20803
20804 Variadic C functions now count arguments with size_t, not int.
20805 This avoids an unnecessary limitation on 64-bit machines, which
20806 caused (substring ...) to crash on large vectors (Bug#8344).
20807 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20808 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20809 All variadic functions and their callers changed accordingly.
20810 (struct gcpro.nvars): Now size_t, not int. All uses changed.
20811 * data.c (arith_driver, float_arith_driver): Likewise.
20812 * editfns.c (general_insert_function): Likewise.
20813 * eval.c (struct backtrace.nargs, interactive_p)
20814 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20815 (funcall_lambda, mark_backtrace): Likewise.
20816 * fns.c (concat): Likewise.
20817 * frame.c (x_set_frame_parameters): Likewise.
20818 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20819 0 if not found, not -1. All callers changed.
20820
20821 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20822 (stack_copy_size): Now size_t, not int.
20823 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20824

20829 All callers changed.
20830
20831 * lisp.h (multibyte_char_to_unibyte):
20832 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20833 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20834 * character.h (CHAR_TO_BYTE8):
20835 * cmds.c (internal_self_insert):
20836 * editfns.c (general_insert_function):
20837 * keymap.c (push_key_description):
20838 * search.c (Freplace_match):
20839 * xdisp.c (message_dolog, set_message_1): All callers changed.
20840
20841 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
20842
20843 * keyboard.c (safe_run_hook_funcall): New function.
20844 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20845 don't set the hook to nil, but remove the offending function instead.
20846 (Qcommand_hook_internal): Remove, unused.
20847 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20848 Vcommand_hook_internal.
20849
20850 * eval.c (enum run_hooks_condition): Remove.
20851 (funcall_nil, funcall_not): New functions.
20852 (run_hook_with_args): Call each function through a `funcall' argument.
20853 Remove `cond' argument, now redundant.
20854 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
20855 (Frun_hook_with_args_until_failure): Adjust accordingly.
20856 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
20857
20858 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20859
20860 * dispextern.h (string_buffer_position): Remove declaration.

20866 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20867 All callers changed.
20868
20869 * w32.c (_wsa_errlist): Use braces for struct initializers.
20870
20871 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

20875 used outside xdisp.c).
20876 (cursor_row_p): Remove parameter `w', unused since
20877 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

20905 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
20906 Replace SIGTYPE with void everywhere.
20907 * s/usg5-4-common.h (SIGTYPE): Remove definition.
20908 * s/template.h (SIGTYPE): Remove commented out definition.
20909
20910 2011-03-26 Eli Zaretskii <eliz@gnu.org>
20911
20912 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
20913 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
20914
20915 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
20916
20917 * w32.c (read_unc_volume): Use parameter `henum', instead of
20918 global variable `wget_enum_handle'.
20919
20920 * keymap.c (describe_vector): Remove parameters `indices' and
20921 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
20922 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
20923
20924 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
20925
20926 * keyboard.c (timer_check): Remove parameter `do_it_now',

20928 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
20929 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.

20938 * process.c (wait_reading_process_output):
20939 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
20940
20941 * insdel.c (adjust_markers_gap_motion):
20942 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
20943 (gap_left, gap_right): Don't call it.
20944
20945 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

20989 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
20990

20992 Don't pass uninitialized region to CombineRgn.
20993
20994 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
20995
20996 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
20997 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
20998 (Fx_close_connection): Remove unused variable `i'.

21000 * w32font.c (w32font_draw): Return number of glyphs.
21001 (w32font_open_internal): Remove unused variable `i'.
21002 (w32font_driver): Add missing initializer.

21020 * window.c (temp_output_buffer_show):

21028 * buffer.c (Fkill_all_local_variables):
21029 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21030 Use Frun_hooks.
21031 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21032 unconditionally since it does the check itself.
21033
21034 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21035
21036 Fix more problems found by GCC 4.5.2's static checks.
21037
21038 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21039 the first time through the loop, since we know p0 < p1 then.
21040 This also avoids a gcc -Wstrict-overflow warning.
21041
21042 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21043 leading to a memory leak, possible in functions like
21044 load_charset_map_from_file that can allocate an unbounded number
21045 of objects (Bug#8318).
21046
21047 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21048 that could (at least in theory) be that large.
21049
21050 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21051 This is less likely to overflow, and avoids undefined behavior if
21052 overflow does occur. All callers changed. Use strtoul to scan
21053 for the unsigned long integer.
21054 (pint2hrstr): Simplify and tune code slightly.
21055 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21056
21057 * scroll.c (do_scrolling): Work around GCC bug 48228.
21058 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
21059
21060 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
21061 This also avoids a warning with gcc -Wstrict-overflow.
21062 (validate_x_resource_name): Simplify count usage.
21063 This also avoids a warning with gcc -Wstrict-overflow.
21064
21065 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21066 fail (Bug#8306).
21067
21068 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21069
21070 * process.c (Fmake_network_process): Use socklen_t, not int,
21071 where POSIX says socklen_t is required in portable programs.
21072 This fixes a porting bug on hosts like 64-bit HP-UX, where
21073 socklen_t is wider than int (Bug#8277).
21074 (Fmake_network_process, server_accept_connection):
21075 (wait_reading_process_output, read_process_output):
21076 Likewise.
21077
21078 * process.c: Rename or move locals to avoid shadowing.
21079 (list_processes_1, Fmake_network_process):
21080 (read_process_output_error_handler, exec_sentinel_error_handler):
21081 Rename or move locals.
21082 (Fmake_network_process): Define label "retry_connect" only if needed.

21093 * terminfo.c: Include tparam.h, to check interfaces.
21094 (tparm): Make 1st arg a const pointer in decl. Put it at top level.

21222
21223 * deps.mk (unexalpha.o): Remove; unused.

21288 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
21289 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21290 some of which prompt warnings from gcc -Wbad-function-cast.
21291 (Fformat_time_string, Fencode_time, Finsert_char):
21292 (Ftranslate_region_internal, Fformat):
21293 Rename or remove local vars to avoid shadowing.

21301
21302 * data.c (Findirect_variable): Name an expression, to avoid

21314 they're used.
21315 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if

21320 (Fmemory_limit): Cast sbrk's returned value to char *.

21325 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21326
21327 Use functions, not macros, for up- and down-casing (Bug#8254).
21328 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21329 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21330 to use the following functions instead of these macros.
21331 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21332 EMACS_INT, since callers assume the returned value fits in int.
21333 (upcase1): Likewise, for UPCASE_TABLE.
21334 (uppercasep, lowercasep, upcase): New static inline functions.
21335 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21344 which gcc can warn about.
21345 (regex_compile, re_match_2_internal): Mark locals as initialized.
21346 (RETALLOC_IF): Define only if needed.
21347 (WORDCHAR_P): Likewise. This one is never needed, but is used
21348 only in a comment talking about a compiler bug, so put inside
21349 the #if 0 of that comment.
21350 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21351 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21365
21366 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.

21370 (Fvertical_motion): Mark locals as initialized.
21371
21372 * casefiddle.c (casify_object, casify_region): Now static.
21373 (casify_region): Mark local as initialized.
21374
21375 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
21376
21377 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21378 New macros, so that the caller can use some names other than
21379 gcpro1, gcpro2, etc.
21380 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21381 of the new macros.
21382 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21383 argument, for consistency with GCPRO2_VAR, etc: it is now the
21384 prefix of the variable, not the variable itself. All uses
21385 changed.
21386 * dired.c (directory_files_internal, file_name_completion):
21387 Rename locals to avoid shadowing.
21388
21389 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21390 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21391 dired.c's scmp function, had undefined behavior.
21392 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21393 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21394 * buffer.h: ... to here, because these macros use current_buffer,
21395 and the new implementation with inline functions needs to have
21396 current_buffer in scope now, rather than later when the macros
21397 are used.
21398 (downcase, upcase1): New static inline functions.
21399 (DOWNCASE, UPCASE1): Reimplement using these functions.
21400 This avoids undefined behavior in expressions like
21401 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21402 from race conditions in accessing the global variables
21403 case_temp1 and case_temp2.
21404 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21405 * lisp.h (case_temp1, case_temp2): Remove their decls.
21406 * character.h (ASCII_CHAR_P): Move from here ...
21407 * lisp.h: ... to here, so that the inline functions mentioned
21408 above can use them.
21409
21410 * dired.c (directory_files_internal_unwind): Now static.
21411
21412 * fileio.c (file_name_as_directory, directory_file_name):
21413 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21414 Now static.
21415 (file_name_as_directory): Use const pointers when appropriate.
21416 (Fexpand_file_name): Likewise. In particular, newdir might
21417 point at constant storage, so make it a const pointer.
21418 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21419 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21420 signedness issues.
21421 (Fset_file_times, Finsert_file_contents, auto_save_error):

21424 * minibuf.c (choose_minibuf_frame_1): Now static.
21425 (Ftry_completion, Fall_completions): Rename or remove locals
21426 to avoid shadowing.
21427
21428 * marker.c (bytepos_to_charpos): Remove; unused.
21429
21430 * lisp.h (verify_bytepos, count_markers): New decls,
21431 so that gcc does not warn that these functions aren't declared.
21432
21433 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21434 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21435 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21436 (copy_text): Remove unused local var.
21437
21438 * filelock.c (within_one_second): Now static.
21439 (lock_file_1): Rename local to avoid shadowing.
21440
21441 * buffer.c (fix_overlays_before): Mark locals as initialized.
21442 (fix_start_end_in_overlays): Likewise. This function should be
21443 simplified by using pointers-to-pointers, but that's a different
21444 matter.
21445 (switch_to_buffer_1): Now static.
21446 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21447 (report_overlay_modification): Rename locals to avoid shadowing.
21448
21449 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21450 Fix pointer signedness issue.

21452 to suppress a gcc -Wclobbered warning that does not seem to be right.
21453 (MAXPATHLEN): Define only if needed.
21454
21455 * process.c (serial_open, serial_configure): Move decls from here ...
21456 * systty.h: ... to here, so that they can be checked.
21457
21458 * fns.c (get_random, seed_random): Move extern decls from here ...
21459 * lisp.h: ... to here, so that they can be checked.
21460
21461 * sysdep.c (reset_io): Now static.
21462 (wait_for_termination_signal): Remove; unused.
21463
21464 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
21465 (copy_keymap_item, append_key, push_text_char_description):
21466 Now static.
21467 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21468 (DENSE_TABLE_SIZE): Remove; unused.
21469 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21470 (describe_map_tree):
21471 Rename locals to avoid shadowing.
21472
21473 * keyboard.c: Declare functions static if they are not used elsewhere.
21474 (echo_char, echo_dash, cmd_error, top_level_2):
21475 (poll_for_input, handle_async_input): Now static.

21484 * keyboard.h (make_ctrl_char): New decl.
21485 (mark_kboards): Move decl here ...
21486 * alloc.c (mark_kboards): ... from here.
21487
