1 2013-01-28 Eli Zaretskii <eliz@gnu.org>
3 * w32.c (opendir): Now accepts a 'const char *'.
5 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
7 Remove obsolete redisplay code. See the discussion at
8 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
9 * dispnew.c (preemption_period, preemption_next_check): Remove.
10 (Vredisplay_preemption_period): Likewise.
11 (update_frame, update_single_window, update_window, update_frame_1):
12 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
13 used, following the 2012-06-22 change.
15 2013-01-25 Eli Zaretskii <eliz@gnu.org>
17 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)

27 2013-01-25 Eli Zaretskii <eliz@gnu.org>
29 * w32.c (max_filename_mbslen): New function.
30 (normalize_filename, readdir): Use it to detect locales where ANSI
31 encoding of file names uses a double-byte character set (DBCS).
32 If a DBCS encoding is used, advance by characters using
33 CharNextExA, instead of incrementing a 'char *' pointer. Use
34 _mbslwr instead of _strlwr. (Bug#13515)
36 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
37 request of memory reservation to 1.7GB. (Bug#13065)
39 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
41 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
42 at check_extra_latin label. (Bug#13505)
44 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
46 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
47 Avoid redundant calls to strlen.
49 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
51 Drop async_visible and async_iconified fields of struct frame.
52 This is possible because async input is gone; for details, see
53 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
54 * frame.h (struct frame): Remove async_visible and async_iconified
55 members, convert garbaged to unsigned bitfield. Adjust comments.
56 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
57 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
58 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
59 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
60 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
62 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
63 properly. Likewise for obscured.
65 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
68 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
70 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
72 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
73 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
75 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
77 * xdisp.c (message2, message2_nolog): Remove functions.
78 (message3, message3_nolog): Extract nbytes and multibyteness directly
79 from the string. Change all callers.
80 (message3_nolog): Don't set message_enable_multibyte since set_message
82 (message1, message1_nolog): Use message3.
83 (vmessage): Use a stack allocated buffer rather than f->message_buf.
84 (with_echo_area_buffer): Remove last two arguments. Update all callers.
85 (set_message): Drop all but the second arg, which has to be a string.
86 (set_message_1): Simplify now that we know that a1 is NULL and the
87 second arg is a string.
88 * frame.h (struct frame): Remove `message_buf' field.
89 Use glyphs_initialized_p instead.
90 (FRAME_MESSAGE_BUF): Remove macro.
91 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
92 * lisp.h (message2, message2_nolog): Remove declarations.
93 (message3, message3_nolog): Update declarations.
94 * keyboard.c (read_char_minibuf_menu_text)
95 (read_char_minibuf_menu_width): Remove vars.
96 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
97 to correctly handle multibyte strings.
98 * frame.c (delete_frame): Don't free message_buf any more.
99 * editfns.c (message_text, message_length): Remove vars.
100 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
101 * fileio.c (auto_save_error): Use message3 instead of message2.
102 * dispnew.c (adjust_frame_message_buffer): Remove function.
104 2013-01-23 Eli Zaretskii <eliz@gnu.org>

109 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
111 * insdel.c (prepare_to_modify_buffer): Force redisplay if
112 hidden buffer is prepared to modification (Bug#13164).
114 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
116 * window.h (struct window): Change window_end_valid member from
117 Lisp_Object to a bitfield. Adjust comments.
118 (wset_window_end_valid): Remove.
119 * window.c (adjust_window_count): Clear window_end_valid.
120 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
121 (Fwindow_line_height, set_window_buffer, Frecenter)
122 (Fsplit_window_internal, Fdelete_other_windows_internal)
123 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
124 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
125 * xdisp.c (check_window_end, reconsider_clip_changes)
126 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
127 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
128 (find_first_unchanged_at_end_row, try_window_id): Likewise.
130 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
132 * xdisp.c (mark_window_display_accurate): Simplify the loop
133 assuming that the only one of vchild, hchild or buffer window
134 slots is non-nil. Call mark_window_display_accurate_1 for
135 the leaf windows only.
136 (mark_window_display_accurate_1): Always assume leaf window.
139 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
141 * emacs.c (Qkill_emacs_hook): Now static.
143 * fileio.c (Finsert_file_contents): Simplify.
144 Remove unnecessary assignments and tests.
146 2013-01-21 Eli Zaretskii <eliz@gnu.org>
148 * w32.c (acl_set_file): Don't test for errors unless
149 set_file_security returns FALSE. Avoids spurious errors when
152 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
154 * fileio.c (Finsert_file_contents): Revert code introduced at
155 2013-01-18 in favor of the simpler and generally better fix.
156 Save stack space by removing 'buffer' and reusing 'read_buf'
159 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
161 * lisp.h (eabs): Define unconditionally (Bug#13419).
162 The old "#if !defined (eabs)" was an unnecessary revenant of back
163 when this macro was called "abs". Document 'eabs' better.
165 2013-01-19 Glenn Morris <rgm@gnu.org>
167 * fns.c (Frandom): Doc fix.
169 2013-01-19 Eli Zaretskii <eliz@gnu.org>
171 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
172 segfault when there are lots of overlays.
174 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
175 when there are lots of overlays. See
176 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
177 for the details and a way to reproduce.
179 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
181 * fileio.c: Use O_APPEND to append.
182 This corresponds better to the natural interpretation of "append",
183 and avoids the need to open the output file twice, or to invoke
184 lseek when APPEND is neither nil nor a number.
185 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
186 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
187 file possibly twice, and lseeking to its end; this avoids the
188 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
189 at the same time: the combination is never needed and apparently
190 it doesn't work with DOS_NT.
192 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
193 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
195 Allow floating-point file offsets.
196 Problem reported by Vitalie Spinu in
197 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
198 * fileio.c (emacs_lseek): Remove.
199 (file_offset): New function.
200 (Finsert_file_contents, Fwrite_region): Use it.
202 2013-01-19 Chong Yidong <cyd@gnu.org>
204 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
205 aborting on Fsignal (Bug#13289).
207 2013-01-19 Eli Zaretskii <eliz@gnu.org>
209 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
210 set_file_security as failure due to insufficient privileges.
211 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
212 (fstat): Return owner and group like 'stat' and 'lstat' do.
214 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
216 Work around bug in CIFS and vboxsf file systems (Bug#13149).
217 The bug was observed on Ubuntu operating inside a virtual machine,
218 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
219 The workaround introduces a race condition on non-buggy hosts,
220 but it's an unlikely race and anyway there's a nearly identical
221 nearby race that can't be fixed.
222 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
224 (Fwrite_region): Test for file system time stamp bug.
225 (init_fileio): New function.
226 * lisp.h (init_fileio): Declare it.
227 * emacs.c (main): Call it.
229 * fileio.c (Finsert_file_contents): Simplify new diagnostic
230 and make it more consistent with other stat-failure diagnostics.
232 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
234 Fix crash when inserting data from non-regular files. See
235 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
236 for the error description produced by valgrind.
237 * fileio.c (read_non_regular): Rename to read_contents.
238 Free Lisp_Save_Value object used to pass parameters.
239 (read_non_regular_quit): Rename to read_contents_quit.
240 (Finsert_file_contents): Redesign internal file reading loop to adjust
241 gap and end positions after each read and so help make_gap to work
242 properly. Do not signal an I/O error too early and so do not leave
243 not yet decoded characters in a buffer, which was the reason of
244 redisplay crash. Use list2 to build return value. Adjust comments.
246 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
248 Close a race when statting and reading files (Bug#13149).
249 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
250 This avoids a race if the file is renamed between stat and open.
251 This race is not the problem originally noted in Bug#13149;
252 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
254 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

261 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
262 * alloc.c (format_save_value): Rename to make_save_value.
263 (make_save_pointer): New function.
264 (record_xmalloc): Use make_save_pointer.
265 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
266 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
267 Change users of make_save_value to make_save_pointer.
268 Likewise for format_save_value and make_save_value.
270 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

285 * fileio.c (non_regular_fd, non_regular_inserted)
286 (non_regular_nbytes): Remove.
287 (Finsert_file_contents): Convert trytry to ptrdiff_t. Use
288 format_save_value to pass parameters to read_non_regular.
289 (read_non_regular): Use XSAVE_ macros to extract parameters.
291 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
293 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
295 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
297 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
298 extraction from any Lisp_Save_Value slot. Add type checking.
299 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
300 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
301 * xselect.c: All users changed.
303 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
305 Some convenient bits to deal with Lisp_Save_Values.
306 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
307 (allocate_misc): Remove prototype.
308 (format_save_value): New prototype.

313 * editfns.c (save_excursion_save): Use format_save_value.
314 (save_excursion_restore): Use XSAVE_OBJECT.
316 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
318 Avoid needless casts with XSAVE_POINTER.
319 * alloc.c (mark_object) [GC_MARK_STACK]:
320 * dired.c (directory_files_internal_unwind):
321 * fileio.c (do_auto_save_unwind):
322 * gtkutil.c (pop_down_dialog):
323 * keymap.c (map_keymap_char_table_item):
324 * lread.c (load_unwind):
325 * nsmenu.m (pop_down_menu):
326 * print.c (print_object) [GC_MARK_STACK]:
327 * xfns.c (clean_up_file_dialog):
328 * xmenu.c (cleanup_widget_value_tree):
329 Omit casts between XSAVE_POINTER and a pointer type.
331 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
333 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
334 * eval.c (eval_sub): Protect `form' from being GCed before its
335 car and cdr becomes protected with the backtrace entry.
337 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
339 Make Lisp_Save_Value more versatile storage for up to four objects.
340 * lisp.h (toplevel): Enumeration to describe types of saved objects.
341 (struct Lisp_Save_Value): New layout. Adjust comments.

343 (XSAVE_INTEGER): Likewise.
344 (allocate_misc): Add prototype.
345 (free_misc): Likewise.
346 * alloc.c (allocate_misc): Now global.
347 (free_misc): Likewise. Adjust comment.
348 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
349 (free_save_value): Likewise.
350 (mark_object): Likewise.
351 * editfns.c (save_excursion_save): Pack everything within
352 Lisp_Save_Value and so avoid xmalloc.
353 (save_excursion_restore): Adjust to match new layout. Use free_misc
354 because we do not allocate extra memory any more. Add eassert.
355 * print.c (print_object): New code to print Lisp_Save_Value. Do not
356 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
357 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
358 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
359 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.
361 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

371 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
372 Move handlers here from emacs.c; they were out of place.
374 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
376 * xterm.c (syms_of_xterm): Adjust documentation for
377 scroll-bar-adjust-thumb-portion.
379 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
381 * xterm.c (scroll-bar-adjust-thumb-portion): New variable to
382 determine whether scroll bar thumb size should be adjusted or
383 not. Use variable for MOTIF.
385 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for
388 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

397 (nsfont_open): Move block_input earlier. Add unblock_input before early
399 (nsfont_draw): Add block/unblock_input calls.
401 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
403 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
404 for old_charpos and old_bytepos.
406 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>

409 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
410 Clear tzvalbuf_in_environ if this workaround is in effect.
411 Problem and fix reported by Kazuhiro Ito.
413 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
415 * insdel.c (Fcombine_after_change_execute, syms_of_insdel): Fix
416 ambiguous doc string cross-reference(s).
418 * keyboard.c (Fcommand_execute, syms_of_keyboard): Fix ambiguous
419 doc string cross-reference(s).
421 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
422 string cross-reference(s).
424 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
426 Avoid unnecessary byte position calculation for the gap movement.
427 Since all users of move_gap do CHAR_TO_BYTE for other purposes
428 anyway, all of them should use move_gap_both instead.
429 * lisp.h (move_gap): Remove prototype.
430 * insdel.c (move_gap): Remove.
431 (move_gap_both): Add eassert.
432 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.
433 * xml.c (parse_region): Likewise.
435 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
437 emacsclient -t should not suspend Emacs server (Bug#13387)
438 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
440 * term.c (init_tty): Use them instead of rolling our own code.
441 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
442 switches from 'signal' to 'pthread_sigmask', which is safer in
443 multithreaded applications.
444 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
445 which has already arranged for that.
446 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
447 This is the main part of the bug fix.
449 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
451 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around

454 2013-01-10 Dmitry Antipov <dmantipov@yandex.ru>
456 Omit buffer_slot_type_mismatch and use generic predicates to enforce
457 the type of per-buffer values where appropriate.
458 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
459 predicate, which is how it's really used now. Adjust comment.
460 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
461 * buffer.c (buffer_slot_type_mismatch): Remove.
462 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
463 predicate. Adjust comment.
464 (syms_of_buffer): Use Qsymbolp for major-mode. Use Qintegerp for
465 fill-column, left-margin, tab-width, buffer-saved-size,
466 left-margin-width, right-margin-width, left-fringe-width,
467 right-fringe-width, scroll-bar-width and buffer-display-count.
468 Use Qstringp for default-directory, buffer-file-name,
469 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
470 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for

515 trailing dash is properly added.
517 2013-01-05 Eli Zaretskii <eliz@gnu.org>
519 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
520 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
521 digits for buffer positions, before misalignment starts.
522 Display "0" for integer "object" field.
523 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
524 Display the newline glyph more unambiguously.
526 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
528 * nsterm.m (ns_draw_underwave):
529 * w32term.c (w32_draw_underwave):
530 * xterm.c (x_draw_underwave): Make underwave look more triangular
531 and also degrade gracefully for small fonts. (Bug#13000)
533 * nsterm.m (ns_draw_text_decoration):
534 * w32term.c (x_draw_glyph_string):
535 * xterm.c (x_draw_glyph_string): Don't use previous underline
536 thickness and position if previous underline type is underwave.
538 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
540 * fileio.c (Ffile_acl): Undocument return format.

549 * dired.c (file_name_completion):
550 * doc.c (get_doc_string):
551 * floatfns.c (round2):
552 * font.c (font_score, font_delete_unmatched):
553 * fringe.c (compute_fringe_widths):
554 * lread.c (read_list):
555 * minibuf.c (Ftry_completion):
556 * term.c (tty_ins_del_lines):
557 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
558 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
560 2012-12-31 Eli Zaretskii <eliz@gnu.org>
562 * w32.c (unsetenv): Set up the string passed to _putenv
564 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
565 for the bug this caused.
567 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
569 * coding.c (Qmac): Now static.
571 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
573 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
574 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
575 handlebox_widget. Set toolbar_in_hbox to false/true, set
576 toolbar_is_packed to true.
577 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
578 (update_frame_tool_bar): Check toolbar_is_packed for packing.
579 Show all on TOOLBAR_TOP_WIDGET.
580 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
581 by TOOLBAR_TOP_WIDGET.
582 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
583 Check toolbar_is_packed.
584 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
585 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
586 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
588 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
589 (xg_update_menubar): Update title only if
590 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
591 (xg_update_submenu): Skip tearoff only if
592 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
593 (xg_initialize): Initialize xg_detached_menus only if
594 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
596 * xterm.h (struct x_output): Surround handlebox_widget with

598 toolbar_in_hbox is bool.
600 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
602 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
603 (LIBS_GNUSTEP): Define.
604 (LIBES): Add $(LIBS_GNUSTEP).

607 2012-12-30 Eli Zaretskii <eliz@gnu.org>
609 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
610 continuation glyph on a TTY with an indication of an empty line.
613 2012-12-29 Eli Zaretskii <eliz@gnu.org>
615 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
616 file's SELinux context or ACLs successfully set, nil otherwise.
618 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
620 * w32proc.c (reader_thread): Avoid passing NULL handles to
621 SetEvent and WaitForSingleObject.
623 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
625 Port EXTERNALLY_VISIBLE to Clang 3.2.
626 * conf_post.h (__has_attribute): New macro.
627 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
629 2012-12-27 Glenn Morris <rgm@gnu.org>
631 * cygw32.c (Fcygwin_convert_file_name_to_windows)
632 (Fcygwin_convert_file_name_from_windows): Doc fixes.
634 2012-12-27 Eli Zaretskii <eliz@gnu.org>
636 * fileio.c (file_name_as_directory, directory_file_name):
637 Accept an additional argument MULTIBYTE to indicate whether the input C
638 came from a multibyte or a unibyte Lisp string; all callers
639 adjusted. Don't assume the input string is always multibyte.
641 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
642 don't ENCODE_FILE them, and return a unibyte string if the input
644 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
645 don't assume the input strings will always be multibyte. If the
646 input strings are multibyte, decode strings obtained from C
649 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
651 * lisp.h (toplevel): Add two notices to the comment about
652 defining a new Lisp data type.
653 * print.c (print_object): If Lisp_Save_Value object's pointer

656 * alloc.c (valid_lisp_object_p): Adjust comment.
658 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
660 * keyboard.c (record_asynch_buffer_change): Initialize an event
661 only if it's really needed.
662 * frame.h (enum output_method): Remove output_mac member since
663 it's a leftover from the deleted code.
664 * frame.c (Fframep): Adjust user here ...
665 * terminal.c (Fterminal_live_p): ... and here.
666 * coding.c (Qmac): Now here because it's only used to denote
667 end-of-line encoding type.
668 (syms_of_coding): DEFSYM it.
669 * frame.h (Qmac): Remove duplicated declaration.
671 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
673 * window.c (select_window_1): Now static, since it's used only here.
675 2012-12-25 Eli Zaretskii <eliz@gnu.org>
677 * window.c (window_body_cols): Subtract display margins from the
678 window body width on TTYs as well. See
679 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
680 for the original report.
682 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
684 * xdisp.c (redisplay_window): Remove inner local variable
685 because the outer shadowed one has the same meaning.
686 * xterm.h (struct x_output): Remove toolbar_detached member since it's
688 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
689 (xg_create_tool_bar): Adjust users.
691 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
693 * buffer.h (BUF_COMPACT): New macro to follow the common style.
694 * buffer.c (Fget_buffer_create): Use it to set compact field of
695 struct buffer_text to avoid accessing an uninitialized value
696 when compact_buffer is called for the first time.
697 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
698 (Fset_buffer_modified_p): Use buffer_window_count to check
699 whether the buffer is displayed in some window.
700 * xdisp.c (message_dolog): Likewise.
702 2012-12-23 Eli Zaretskii <eliz@gnu.org>
704 * w32.c (acl_set_file): If setting the file security descriptor
705 fails, and the new DACL is identical to the existing one, silently
706 return success. This fixes problems for users backing up their
707 own files without having the necessary privileges for setting
708 security descriptors.
710 * w32proc.c (reader_thread): Do not index fd_info[] with negative
712 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
713 after WaitForSingleObject returns normally. This expedites reader
714 thread shutdown when delete_child triggers it.
715 (reap_subprocess): More accurate commentary for why we call
716 delete_child only when cp->fd is negative.
718 * w32.c (sys_close): Do not call delete_child on a subprocess
719 whose handle is not yet closed. Instead, set its file descriptor
720 to a negative value, so that reap_subprocess will call
721 delete_child on that subprocess when its SIGCHLD arrives.
722 This avoids closing handles used for communications between sys_select
723 and reader_thread, which doesn't give sys_select a chance to
724 notice that the process exited and invoke the SIGCHLD handler for
727 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
729 * nsfns.m (Fns_do_applescript): Run event loop until script has
730 been executed (Bug#12969).
731 (ns_run_ascript): Chech as_script for nil, set to nil after
734 2012-12-22 Martin Rudalics <rudalics@gmx.at>
736 * window.c (Fselect_window): Reword doc-string (Bug#13248).

740 * w32term.c (w32fullscreen_hook): New function.
741 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
743 2012-12-21 Eli Zaretskii <eliz@gnu.org>
745 * fileio.c (Finsert_file_contents): Doc fix.
747 * w32proc.c (new_child, delete_child, find_child_pid): For a
748 subprocess, consider its slot being in use as long as its process
749 handle (procinfo.hProcess) is not NULL. This avoids reusing the
750 slot when a new process is started immediately after killing
751 another one, without waiting enough time for the first process to
752 be reaped and resources allocated for it be orderly freed.
754 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
756 2012-12-21 Chong Yidong <cyd@gnu.org>
758 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
760 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
762 2012-12-21 Eli Zaretskii <eliz@gnu.org>
764 * w32.c (get_name_and_id): Always pass NULL as the first argument
765 of lookup_account_sid. Avoids crashes with UNC file names that
766 refer to DFS domains, not to specific machine names. (Bug#12621)
767 Remove now unused argument FNAME; all callers changed.
768 (get_file_owner_and_group): Remove now unused argument FNAME; all
771 2012-12-21 Chong Yidong <cyd@gnu.org>
773 * editfns.c (Finsert_char): Since read-char-by-name now signals an
774 error for invalid chars, don't check for a nil return value.
776 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
778 Avoid calls to CHAR_TO_BYTE if byte position is known.
779 * editfns.c (make_buffer_string_both): Use move_gap_both.
780 (Fbuffer_string): Use make_buffer_string_both.
781 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
783 (buf_bytepos_to_charpos): Likewise.
784 (charpos_to_bytepos): Remove.
785 * fileio.c (Finsert_file_contents): Use move_gap_both.
786 * search.c (Freplace_match): Likewise.
787 * process.c (process_send_region): Likewise. Use convenient
788 names for byte positions.
789 * lisp.h (charpos_to_bytepos): Remove prototype.
790 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
791 * insdel.c (move_gap): Likewise.
793 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
795 * xdisp.c (redisplay_internal): Remove now-unused local.
797 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
799 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
800 (redisplay_internal): Don't bother selecting the frame to get the
801 proper value of frame-local variables (bug#13225).
803 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
805 * textprop.c (set_text_properties_1): Do not allow NULL interval.
806 Rename 4th argument since it may be buffer or string. Adjust comment.
807 * intervals.c (graft_intervals_info_buffer): Find an interval here.
809 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
811 * coding.c (Fdetect_coding_region): Do not check start and end with
812 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
813 (code_convert_region): Likewise.
815 2012-12-18 Eli Zaretskii <eliz@gnu.org>
817 * w32.c (acl_get_file, acl_set_file): Run the file name through
818 map_w32_filename, and resolve any symlinks in the file name, like
820 (acl_set_file): Call revert_to_self, if any privileges were

826 ($(BLD)/w32.$(O)): Update dependencies.
828 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
830 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
831 propagate redisplay's scrolling (if any) to the right window.
832 (redisplay_internal): Use ensure_selected_frame.
833 (display_mode_lines): Complete last fix.
834 * window.c (select_window_1): New func, extracted from select_window.
835 (select_window): Use it.
836 * window.h (select_window_1): Declare.
838 2012-12-17 Eli Zaretskii <eliz@gnu.org>
840 Emulate Posix ACL APIs on MS-Windows.
841 * w32.c: Include sddl.h and sys/acl.h.
842 (SDDL_REVISION_1): Define if not already defined.

860 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
862 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
864 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
865 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
866 for some of that bug's symptoms can now cause Emacs to abort.
867 Remove the workaround.
868 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
869 The bug that caused SIGCHLD to get lost has been fixed, and the
870 workaround for it can now cause Emacs to abort.
872 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
874 * sysdep.c (emacs_abort): Bump backtrace size to 40.
875 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
876 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
878 2012-12-16 Romain Francoise <romain@orebokech.com>
880 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
881 (Fcopy_file): Change last arg to `preserve_extended_attributes'
882 and copy ACL entries of file in addition to SELinux context if set.
883 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
885 * Makefile.in (LIBACL_LIBS): New macro.
888 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
890 * fileio.c (internal_delete_file): Use bool for boolean.
892 2012-12-15 Eli Zaretskii <eliz@gnu.org>
894 Fix bug #13079 on MS-Windows with temp files not being deleted.
895 * w32.h (_child_process): New members input_file and
897 (register_child): First argument is now pid_t.
898 (record_infile, record_pending_deletion): New prototypes.
900 * w32proc.c (new_child): Initialize input_file and
901 pending_deletion members of the child.
902 (delete_child): Delete the child's temporary input file, if any,
903 that is pending deletion.
904 (register_child): First argument is now pid_t.
905 (record_infile, record_pending_deletion): New functions.
906 (reap_subprocess): Fix a typo in DebPrint string.
907 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
909 * fileio.c (internal_delete_file): Return an int again: non-zero
910 if delete-file succeeds, zero otherwise.
912 * lisp.h (internal_delete_file): Adjust prototype.
914 * callproc.c (Fcall_process): Don't overwrite infile with result
916 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
917 asynchronous subprocess, record the name of the input file name,
919 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
920 delete the file, record it as pending deletion when the subprocess
923 2012-12-14 Eli Zaretskii <eliz@gnu.org>
925 * editfns.c [HAVE_PWD_H]: Include grp.h.
927 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
929 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
931 Fix permissions bugs with setgid directories etc. (Bug#13125)
932 * dired.c (Ffile_attributes): Return t as the 9th attribute,
933 to mark it as a placeholder. The old value was often wrong.
934 The only user of this attribute has been changed to use
935 file-ownership-preserved-p instead, with its new group arg.
936 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
938 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

943 2012-12-14 Eli Zaretskii <eliz@gnu.org>
945 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
946 try to get accurate owner and group information from NT file
947 security APIs. This is to make most callers of 'stat' and
948 'lstat', which don't need that information, much faster.
950 * dired.c (Ffile_attributes) [WINDOWSNT]:
951 Set w32_stat_get_owner_group to a non-zero value, to request accurate
952 owner and group information from 'lstat'.
954 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
956 * fileio.c (Finsert_file_contents): Don't put tail into head area,
957 as that confuses set-auto-coding, so insist on the head-read
958 returning the full 1024 bytes. Let lseek compute the tail offset;
959 less work for us. Do not ignore I/O errors when reading the tail.
961 * xdisp.c: Minor style fixes.
962 (init_iterator): Hoist assignment out of if-expression.
963 (markpos_of_region): Callers now test for sign, not for -1.
965 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
967 Minor redisplay optimization when the region length is zero.
968 * xdisp.c (markpos_of_region): New function.

1075 (hinst): Remove unneeded extern declaration.
1076 (_start): Remove initialization of above variables; remove

1225 * dbusbind.c (Fdbus_init_bus):
1227 * xterm.c (x_term_init):

1238 no longer needed here.
1239 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:

1241 (set_time_zone_rule): Maintain the TZ=value string separately.
1242 (syms_of_editfns): Don't initialize initial_tz;
1243 init_editfns now does it.
1244 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.

1262 Simplify get_lim_data.
1263 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1264 Remove USG and vlimit methods; no longer used these days.
1265 Add #error catchall just in case.
1267 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1268 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1269 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

1294 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1296 * frame.c (make_frame): Do not set window's buffer to t.
1297 * window.c (Fsplit_window_internal): Likewise. Previously it was
1298 used to indicate that the window is being set up. Now we use
1299 set_window_buffer for all new windows, so the condition in ...
1300 (Fset_window_buffer): ... is always true and can be removed.
1302 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1304 Convenient macro to check whether the buffer is hidden.
1305 * buffer.h (BUFFER_HIDDEN_P): New macro.

1312 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG

1314 loop and return zero. (Bug#13086)
1316 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1318 * frame.h (x_char_width, x_char_height): Remove prototypes.

1331 Fix a recently-introduced delete-process race condition.
1332 * callproc.c, process.h (record_kill_process):
1333 New function, containing part of the old call_process_kill.
1334 (call_process_kill): Use it.
1335 This does not change call_process_kill's behavior.
1336 * process.c (Fdelete_process): Use record_kill_process to fix a
1337 race condition that could cause Emacs to lose track of a child.
1339 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1341 Avoid code duplication between prev_frame and next_frame.
1342 * frame.c (candidate_frame): New function. Add comment.

1345 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1347 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1348 fails, signal an error instead of continuing with an empty
1350 Encode expanded temp file pattern before passing it to mkstemp or
1353 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1354 Encode the file name before passing it to dostounix_filename, in
1355 case it will downcase it (under w32-downcase-file-names).
1358 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1360 Minor call-process cleanups.
1361 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1362 at the same time as other platforms, to simplify analysis.
1363 No need for fd0_volatile since we have synch_process_fd.
1364 Avoid needless emacs_close; arg is always negative.
1366 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1368 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

1373 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1374 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1375 and mouse_face_hidden members to a bitfields.

1380 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1381 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1382 members to a bitfields.
1384 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1386 Don't let call-process be a zombie factory (Bug#12980).
1387 Fixing this bug required some cleanup of the signal-handling code.
1388 As a side effect, this change also fixes a longstanding rare race
1389 condition whereby Emacs could mistakenly kill unrelated processes,
1390 and it fixes a bug where a second C-g does not kill a recalcitrant
1391 synchronous process in GNU/Linux and similar platforms.
1392 The patch should also fix the last vestiges of Bug#9488,
1393 a bug which has mostly been fixed on the trunk by other changes.
1394 * callproc.c, process.h (synch_process_alive, synch_process_death)
1395 (synch_process_termsig, sync_process_retcode):
1396 Remove. All uses removed, to simplify analysis and so that
1397 less consing is done inside critical sections.
1398 * callproc.c (call_process_exited): Remove. All uses replaced
1399 with !synch_process_pid.
1400 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1401 These take the role of what used to be in unwind-protect arg.
1403 (block_child_signal, unblock_child_signal):
1404 New functions, to avoid races that could kill innocent-victim processes.
1405 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1406 (call_process_kill): Record killed processes as deleted, so that
1407 zombies do not clutter up the system. Do this inside a critical
1408 section, to avoid a race that would allow the clutter.
1409 (call_process_cleanup): Fix code so that the second C-g works again
1410 on common platforms such as GNU/Linux.
1411 (Fcall_process): Create the child process in a critical section,
1412 to fix a race condition. If creating an asynchronous process,
1413 record it as deleted so that zombies do not clutter up the system.
1414 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1415 light of these changes. Omit unnecessary call to emacs_close
1416 before failure, as the unwind-protect code does that.
1417 * callproc.c (call_process_cleanup):
1418 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1419 * process.c (record_deleted_pid): New function, containing
1420 code refactored out of Fdelete_process.
1421 (Fdelete_process): Use it.
1422 (process_status_retrieved): Remove. All callers changed to use
1423 child_status_change.
1424 (record_child_status_change): Remove, folding its contents into ...
1425 (handle_child_signal): ... this signal handler. Now, this
1426 function is purely a handler for SIGCHLD, and is not called after
1427 a synchronous waitpid returns; the synchronous code is moved to
1428 wait_for_termination. There is no need to worry about reaping
1429 more than one child now.
1430 * sysdep.c (get_child_status, child_status_changed): New functions.
1431 (wait_for_termination): Now takes int * status and bool
1432 interruptible arguments, too. Do not record child status change;
1433 that's now the caller's responsibility. All callers changed.

1500 Fix xpalloc confusion after memory is exhausted.
1501 * alloc.c (xpalloc): Comment fix.
1502 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory

1548 Do not assume that fd[0], count, filefd, and save_environ survive
1549 vfork. Fix bug whereby wrong errno value could be reported for
1550 pipe failure. Some minor cleanups, too, as follows. Move buf and
1551 bufsize to the context where they're needed. Change new_argv to
1552 be of type char **, as this is more convenient and avoids casts.
1553 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1554 Now local constants, not macros.
1556 2012-11-18 Kenichi Handa <handa@gnu.org>

1606 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1607 between bpos_covered and bpos_max. This fixes cursor display when
1608 several display strings follow each other.
1610 * .gdbinit (pgx): If the glyph's object is a string, display the
1611 pointer to string data, rather than the value of the string object
1612 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1614 * indent.c (Fvertical_motion): If the starting position is covered
1615 by a display string, return to one position before that, to avoid
1616 overshooting it inside move_it_to. (Bug#12930)

1661 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>

1667 * w32term.c (w32_frame_up_to_date): ...here...
1668 * xterm.c (XTframe_up_to_date): ...and here...

1711 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1713 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1714 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:

1772 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1774 * w32select.c: Include w32common.h before w32term.h, so that
1775 windows.h gets included before w32term.h uses some of its
1776 features, see below.

1812 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1813 (create_pty, Fmake_network_process, server_accept_connection)
1814 (wait_reading_process_output, init_process_emacs):
1816 (wait_reading_process_output): Put in a special case for WINDOWSNT
1817 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1818 It's not clear this is needed, but it's a more-conservative change.
1819 (create_process): Assume FD_CLOEXEC.
1820 (create_process, create_pty): Assume O_NOCTTY.
1821 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.

1825 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1827 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1828 lack it, since gnulib guarantees this.

1837 process to fit into an Emacs integer, as this is no longer a
1839 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1840 reaping only the process specified by PID argument, if that is
1841 positive. Use PID instead of dead_child to know which process to
1842 reap. Wait for the child to die only if WNOHANG is not in
1844 (sys_select): Don't set dead_child.
1846 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1847 as it is no longer needed.

1856 Fix problems in ns port found by static checking.
1857 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1858 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1859 not to process group.
1860 (ns_select): Use emacs_write, not write, as that's more robust
1861 in the presence of signals.

1875 use the same value of thread handle.
1876 (start_timer_thread): If the timer thread exited (due to error),
1877 clean up by closing the two handles it used. Duplicate the caller
1878 thread's handle here, so it gets duplicated only once, when
1879 launching the timer thread. Set priority of the timer thread, not
1881 (getitimer): Don't duplicate the caller thread's handle here.
1884 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1886 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is

1891 Remove no-longer-used pty_max_bytes variable.
1892 * process.c (pty_max_bytes): Remove; unused.

1900 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1902 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1903 This follows up on the 2012-09-29 patch that removed indirection
1904 for the 'function' field. Reported by Sergey Vinokurov in
1905 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1907 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1909 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1910 different name, as the MS runtime does not have such a function,
1911 and probably never will.) All callers changed. Ignore DIRFD
1912 value if PATH is an absolute file name, to match Posix spec
1913 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1916 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1918 * xdisp.c (echo_area_display, redisplay_internal):
1919 Omit redundant check whether frame_garbaged is set.
1921 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1923 Use faccessat, not access, when checking file permissions (Bug#12632).
1924 This fixes a bug that has been present in Emacs since its creation.
1925 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1926 which must set some sort of record. (Torek's bug report was against
1927 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1928 same common flaw.) See Torek's Usenet posting
1929 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1930 Posted: Fri Apr 8 14:18:56 1983.
1931 * Makefile.in (LIB_EACCESS): New macro.
1933 * callproc.c (init_callproc):
1934 * charset.c (init_charset):
1935 * fileio.c (check_existing, check_executable, check_writable)
1937 * lread.c (openp, load_path_check):
1938 * process.c (allocate_pty):
1940 Use effective UID when checking permissions, not real UID.
1941 * callproc.c (init_callproc):
1942 * charset.c (init_charset):
1943 * lread.c (load_path_check, init_lread):
1944 Test whether directories are accessible, not merely whether they exist.
1945 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1946 * fileio.c (check_existing, check_executable, check_writable)
1948 Use symbolic names instead of integers for the flags, as they're
1950 (check_writable): New arg AMODE. All uses changed.
1951 Set errno on failure.
1952 (Ffile_readable_p): Use faccessat, not stat + open + close.
1953 (Ffile_writable_p): No need to call check_existing + check_writable.
1954 Just call check_writable and then look at errno. This saves a syscall.
1955 dir should never be nil; replace an unnecessary runtime check
1956 with an eassert. When checking the parent directory of a nonexistent
1957 file, check that the directory is searchable as well as writable, as
1958 we can't create files in unsearchable directories.
1959 (file_directory_p): New function, which uses 'stat' on most platforms
1960 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1961 (Ffile_directory_p, Fset_file_times): Use it.
1962 (file_accessible_directory_p): New function, which uses a single
1963 syscall for efficiency.
1964 (Ffile_accessible_directory_p): Use it.
1965 * xrdb.c (file_p): Use file_directory_p.
1966 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1967 * lread.c (openp): When opening a file, use fstat rather than
1968 stat, as that avoids a permissions race. When not opening a file,
1969 use file_directory_p rather than stat.
1970 (dir_warning): First arg is now a usage string, not a format.
1971 Use errno. All uses changed.
1972 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1973 that merely introduced a race.
1974 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1975 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1976 and similarly for the other O_* flags.
1977 * w32.c (sys_faccessat): Rename from sys_access and switch to
1978 faccessat's API. All uses changed.
1979 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1980 (magic_db): Rename from magic_file_p.
1981 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1982 char *, so that we don't have to test for file existence
1983 separately from opening the file for reading. This removes a race
1984 fixes a permission-checking problem, and simplifies the code.
1986 (file_p): Remove; no longer needed.
1988 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1990 Omit glyphs initialization at startup.
1991 * dispnew.c (glyphs_initialized_initially_p): Remove.
1992 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1993 (Fredraw_frame): Move actual code from here...
1994 (redraw_frame): ...to here. Add eassert. Adjust comment.
1995 (Fredraw_display): Use redraw_frame.
1996 * xdisp.c (clear_garbaged_frames): Likewise.
1998 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2000 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2001 passed to pint2str and pint2hrstr to be at most the size of the
2002 frame's decode_mode_spec_buffer. This avoids crashes with very
2003 large values of FIELD_WIDTH argument to decode_mode_spec.
2006 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2008 Fix a race with verify-visited-file-modtime (Bug#12863).
2009 Since at least 1991 Emacs has ignored an mtime difference of no
2010 more than one second, but my guess is that this was to work around
2011 file system bugs that were fixed long ago. Since the race is
2012 causing problems now, let's remove that code.
2013 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2014 whose time stamp is off by no more than a second. Insist that the
2015 file time stamps match exactly.
2017 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2019 * frame.h (struct frame): Convert external_tool_bar member to
2020 1-bit unsigned bitfield.
2021 * termhooks.h (struct terminal): Remove mouse_moved member since
2022 all users are long dead. Adjust comment on mouse_position_hook.
2024 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2026 Simplify by using FOR_EACH_FRAME here and there.
2027 * frame.c (next_frame, prev_frame, other_visible_frames)
2028 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2029 * w32term.c (x_window_to_scroll_bar): Likewise.
2030 * window.c (window_list): Likewise.
2031 * xdisp.c (x_consider_frame_title): Likewise.
2032 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2033 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2034 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2035 * xmenu.c (menubar_id_to_frame): Likewise.
2036 * xselect.c (frame_for_x_selection): Likewise.
2037 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2038 (x_window_to_menu_bar): Likewise.
2039 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2041 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2043 * data.c (Qdefalias_fset_function): Now static.
2045 Another tweak to vectorlike_header change.
2046 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2047 Remove, and replace all uses with ...
2048 (next_in_free_list, set_next_in_free_list):
2049 New functions, which respect C's aliasing rules better.
2051 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2053 * window.c (list4i): Rename from 'quad'. All uses changed.
2054 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2056 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2058 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2059 warning about mixing declarations and code in ISO C90.
2061 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2063 * window.c (Fsplit_window_internal): Set combination limit of
2064 new parent window to t iff Vwindow_combination_limit is t;
2065 fixing a regression introduced with the change from 2012-09-22.
2066 (Fset_window_combination_limit): Fix doc-string.
2068 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2070 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2071 amount when the scroll margins are too large. When scrolling
2072 backwards in the buffer, give up if cannot reach point or the
2073 scroll margin within a reasonable number of screen lines.
2074 Fixes point position in window under scroll-up/down-aggressively when
2075 point is positioned many lines beyond the window top/bottom.
2078 * ralloc.c (relinquish): If real_morecore fails to return memory
2079 to the system, don't crash; instead, leave the last heap
2080 unchanged and return. (Bug#12774)
2082 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2084 * lisp.h (AUTOLOADP): New macro.
2085 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.

2087 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2089 (Finteractive_form): Simplify.
2090 (Fquo): Don't insist on having at least 2 arguments.
2091 (Qdefalias_fset_function): New var.
2093 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2095 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2097 * nsfont.m (Qcondensed, Qexpanded): New variables.

2099 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2101 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2103 Fix recently introduced crash on MS-Windows (Bug#12839).
2104 * w32term.h (struct scroll_bar): Use convenient header.
2105 (SCROLL_BAR_VEC_SIZE): Remove.
2106 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2108 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2110 Tweak last vectorlike_header change.
2111 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2112 vectorlike object on the free list. This is introduced to avoid
2113 some (but not all) pointer casting and aliasing problems, see
2114 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2115 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2117 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2119 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2121 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2122 been removed, so remove them here also.
2124 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2126 * doc.c (Fdocumentation): Handle new property
2127 dynamic-docstring-function to replace the old ad-advice-info.
2129 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2131 * fns.c (Qeql, hashtest_eq): Now static.
2133 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2135 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2136 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2137 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2138 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2140 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2142 Use same hash function for hashfn_profiler as for hash_string etc.
2143 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2144 * lisp.h (sxhash_combine): New inline function, with the contents
2145 of the old SXHASH_COMBINE.
2146 * profiler.c (hashfn_profiler): Use it, instead of having a
2147 special hash function containing a comparison that always yields 1.
2149 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2151 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2152 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2153 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2156 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2158 * image.c (xpm_make_color_table_h): Fix compiler error because
2159 make_hash_table changed.

2163 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2165 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2167 Use ad-hoc comparison function for the profiler's hash-tables.
2168 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2169 (make_log): Use them.
2170 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2171 call Fequal any more.

2180 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2181 (hash_lookup, hash_remove_from_table): Move assertion checking of
2182 hashfn result here. Check hash-equality before calling cmpfn.

2195 value of w32-scroll-lock-modifier is neither nil nor one of the
2196 known key modifiers. (Bug#12806)
2198 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2200 Shrink struct vectorlike_header to the only size field.
2201 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2203 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2204 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2205 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2206 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2207 information from the vector header. Adjust comment.

2219 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2220 (Fmake_bool_vector): Likewise.
2221 (struct large_vector): New type to represent allocation unit for
2222 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2223 (large_vectors): Change type to struct large_vector.
2224 (allocate_vector_from_block): Simplify.
2225 (PSEUDOVECTOR_NBYTES): Replace with...
2226 (vector_nbytes): ...new function. Adjust users.
2227 (sweep_vectors): Adjust processing of large vectors.

2232 (live_vector_p): Adjust to match large vector.
2233 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2234 * buffer.h (struct buffer): Add next member.
2235 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2237 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

2245 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2247 * keyboard.c (event_to_kboard): Do not dereference
2248 frame_or_window field of SELECTION_REQUEST_EVENT
2249 and SELECTION_CLEAR_EVENT events (Bug#12814).
2250 * xterm.h (struct selection_input_event): Adjust comment.
2252 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2254 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2255 such as Scroll Lock, if the respective keys are treated as
2256 function keys, not as modifiers. This avoids destroying non-ASCII
2257 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2259 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2261 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2263 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2265 Restore some duplicate definitions (Bug#12814).
2266 This undoes part of the 2012-11-03 changes. Some people build
2267 with plain -g rather than with -g3, and they need the duplicate
2268 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2269 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2270 Define as macros, as well as as enums or as constants.
2272 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2274 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2275 to keypad keys (Bug#12816).
2277 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2279 Minor adjustments of recently-changed frame functions.
2280 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2281 known to be a frame (we're in the FRAMEP branch).
2282 * lisp.h (Qframep): Remove decl. frame.h declares this.
2283 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2284 since they're meant for Lisp fixnum values.
2286 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2288 * window.c (Fwindow_combination_limit): Revert to the only
2289 required argument and adjust docstring as suggested in
2290 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2291 by Martin Rudalics <rudalics@gmx.at>.

2332 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2333 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2334 (Fwindow_line_height): Use it.
2335 (Fwindow_fringes): Use list3.
2336 (Fwindow_scroll_bars): Use list4.
2337 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2338 (Fwindow_combination_limit): Allow zero number of arguments.
2340 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2342 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2344 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2345 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2346 file descriptor 2 for standard error. (Bug#12805)
2348 2012-11-05 Chong Yidong <cyd@gnu.org>
2350 * process.c (wait_reading_process_output): Revert previous change.
2352 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2354 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2355 This removes code that has been obsolete since around 1990.
2356 * callproc.c (Fcall_process):
2358 * process.c (create_process):
2359 * term.c (dissociate_if_controlling_tty):
2360 Assume setsid exists.
2361 * callproc.c (child_setup): Assume setpgid exists and behaves as
2362 per POSIX.1-1988 or later.
2363 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2364 * emacs.c (shut_down_emacs):
2365 * sysdep.c (sys_suspend, init_foreground_group):
2366 Assume getpgrp behaves as per POSIX.1-1998 or later.
2367 * msdos.c (setpgrp): Remove.
2368 (tcgetpgrp, setpgid, setsid): New functions.
2369 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2370 * term.c (no_controlling_tty): Remove; unused.
2371 * w32proc.c (setpgrp): Remove.
2372 (setsid, tcgetpgrp): New functions.
2374 Simplify by assuming __fpending.
2375 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2376 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2377 Do not assume that __fpending's result fits in int.
2379 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2381 Remove EMACS_OUTQSIZE+sleep hack.
2382 * dispnew.c (update_frame_1): Remove hack for terminals slower
2383 than 2400 bps, which throttled Emacs by having it sleep.
2384 This code hasn't worked since at least 2007, when the multi-tty stuff
2385 was added, and anyway those old terminals are long dead.
2386 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2387 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2389 Fix data-loss with --version (Bug#9574).
2390 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2391 as we can't assume that emacs_strerror is initialized, and strerror
2392 is good enough here.
2393 (main): Invoke atexit earlier, to catch earlier instances of
2394 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2396 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2398 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2399 (keyDown): Remap keypad keys to X11 virtual key codes.
2401 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2403 Fix data-loss with --batch (Bug#9574).
2404 * emacs.c: Include <close-stream.h>.
2405 (close_output_streams): New function.
2406 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2407 and handles errors appropriately.
2408 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2411 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2412 The symptom is a diagnostic "GLib-WARNING **: In call to
2413 g_spawn_sync(), exit status of a child process was requested but
2414 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2415 waitpid(), so exit status can't be returned." The diagnostic
2416 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2417 The real bug is a race condition between Emacs and glib: Emacs
2418 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2419 so that glib can't find it. Work around the bug by invoking
2420 waitpid only on subprocesses that Emacs itself creates.
2421 * process.c (create_process, record_child_status_change):
2422 Don't use special value -1 in pid field, as the caller now must
2423 know the pid rather than having the callee infer it.
2424 The inference was sometimes incorrect anyway, due to another race.
2425 (create_process): Set new 'alive' member if child is created.
2426 (process_status_retrieved): New function.
2427 (record_child_status_change): Use it.
2428 Accept negative 1st argument, which means to wait for the
2429 processes that Emacs already knows about. Move special-case code
2430 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2431 processes that have already been waited for, by testing and
2432 clearing new 'alive' member.
2433 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2434 now does this internally.
2435 (handle_child_signal): Let record_child_status_change do all
2436 the work, since we do not want to reap all exited child processes,
2437 only the child processes that Emacs itself created.
2438 * process.h (Lisp_Process): New boolean member 'alive'.
2440 Omit duplicate definitions no longer needed with gcc -g3.
2441 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2442 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2443 Define only as macros. There's no longer any need to also define
2444 these symbols as enums or as constants, since we now assume
2445 gcc -g3 when debugging.
2447 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2449 * lisp.mk: Adjust comments to the fact that term/internal is now
2450 loaded from loadup.el.
2452 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2453 (msdos_fatal_signal): New function.
2454 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2457 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2458 for GCC versions before 4.
2459 (emacs_raise): Define to call msdos_fatal_signal.
2461 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2462 iterator when starting in the middle of a display or overlay
2465 2012-11-03 Chong Yidong <cyd@gnu.org>
2467 * process.c (wait_reading_process_output): Clean up the last
2470 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2472 * process.c (wait_reading_process_output): Avoid a race condition
2473 with SIGIO delivery (Bug#11536).
2475 2012-11-03 Chong Yidong <cyd@gnu.org>
2477 * buffer.c (cursor_type): Untabify docstring.
2479 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2481 * frame.h (struct frame): Drop can_have_scroll_bars member
2482 which is meaningless for a long time. Adjust comments.
2483 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2484 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2486 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2488 * window.c (decode_next_window_args): Update window arg after
2489 calling decode_live_window and so fix crash reported at
2490 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2491 by Juanma Barranquero <lekktu@gmail.com>.
2492 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2493 * font.c (Ffont_at): Likewise.
2495 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2497 * widget.c (resize_cb): New function.
2498 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2499 (EmacsFrameResize): Check if all is up to date before changing frame
2502 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2504 Implement backtrace output for fatal errors on MS-Windows.
2505 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2506 (BACKTRACE_LIMIT_MAX): New macro.
2507 (w32_backtrace): New function.
2508 (emacs_abort): Use w32_backtrace when the user chooses not to
2509 attach a debugger. Update the text of the abort dialog.
2511 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2513 Window-related stuff cleanup here and there.
2514 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2515 Use decode_any_window.
2516 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2517 * xdisp.c (Fformat_mode_line): Likewise.
2518 * font.c (Ffont_at): Use decode_live_window.
2519 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2520 * window.c (decode_next_window_args): Likewise.
2521 (decode_any_window): Remove static.
2522 * window.h (decode_any_window): Add prototype.
2523 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2524 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2527 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2529 Remove pad from struct input_event.
2530 * termhooks.h (struct input_event): Remove padding field.
2532 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2533 member is never cons for a long time. Adjust comment.
2534 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2535 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2536 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2537 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2539 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2541 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2543 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2545 Fix crash when using Emacs as commit editor for git (Bug#12697).
2546 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2547 and it is configured in conf_post.h.
2548 (Fcall_process): Don't invoke both setsid and setpgid; the former
2549 is enough, if it exists.
2550 * callproc.c (Fcall_process, child_setup):
2551 * process.c (create_process): Use setpgid.
2552 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2554 * dispnew.c (init_display): Initialize the foreground group
2555 if we are running a tty display.
2556 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2557 * lisp.h (init_foreground_group): New decl.
2558 * sysdep.c (inherited_pgroup): New static var.
2559 (init_foreground_group, tcsetpgrp_without_stopping)
2560 (narrow_foreground_group, widen_foreground_group): New functions.
2561 (init_sys_modes): Narrow foreground group.
2562 (reset_sys_modes): Widen foreground group.
2564 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2566 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2568 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2570 * minibuf.c (read_minibuf): Restore current buffer since
2571 choose_minibuf_frame calling Fset_frame_selected_window may
2572 change it (Bug#12766).
2574 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2576 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2578 2012-10-30 Kenichi Handa <handa@gnu.org>
2580 * font.c (Ffont_at): If WINDOW is specified and it is not
2581 displaying the current buffer, signal an error.
2583 2012-10-29 Daniel Colascione <dancol@dancol.org>
2585 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2586 In preparation for fixing bug#12739, move these functions from
2589 * coding.h, coding.c: ... to here, and compile them only when
2590 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2591 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2593 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2595 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2596 (timer_loop, getitimer, setitimer): Use it instead of
2597 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2599 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2602 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2604 * nsterm.m (NO_APPDEFINED_DATA): New define.
2605 (last_appdefined_event_data): New variable
2606 (last_appdefined_event): Remove.
2607 (ns_select): Initialize t from last_appdefined_event_data instead
2608 of [last_appdefined_event data1].
2609 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2610 remove last_appdefined_event (Bug#12698).
2612 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2614 * frame.c (x_set_font): Catch internal error.
2616 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2618 Avoid overflow in w32 implementation of interval timers.
2619 When possible, for ITIMER_PROF count only times the main thread
2621 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2622 'volatile ULONGLONG' types. All the other data which was
2623 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2624 (GetThreadTimes_Proc): New typedef.
2625 (w32_get_timer_time): New function, returns a suitable time value
2627 (timer_loop): Enter critical section when accessing ULONGLONG
2628 values of the itimer_data struct, as these accesses are no longer
2629 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2630 Remove unused variable.
2631 (init_timers): Initialize s_pfn_Get_Thread_Times.
2632 (start_timer_thread): Don't assign itimer->caller_thread here.
2633 (getitimer): Assign itimer->caller_thread here.
2634 (setitimer): Always call getitimer to get the value of ticks_now.
2635 (sys_spawnve): Avoid compiler warning about format mismatch.
2637 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2639 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2640 mouse movement events if the menu bar is active. This avoids
2641 producing a busy "hour-glass" cursor by Windows if the mouse
2642 pointer is positioned over a tooltip shown for some menu item.
2644 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2646 Don't assume process IDs fit in int.
2647 * emacs.c (shut_down_emacs) [!DOS_NT]:
2648 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2649 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2650 Use pid_t, not int, to store process IDs, as 'int'
2651 is not wide enough on a few platforms (e.g., AIX and IRIX).
2653 2012-10-23 Kenichi Handa <handa@gnu.org>
2655 The following change is to make face-font-rescale-alist work
2656 correctly for non-ASCII fonts.
2658 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2659 (font_open_for_lface): Handle Vface_font_rescale_alist.
2661 2012-10-23 Chong Yidong <cyd@gnu.org>
2663 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2665 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2667 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2669 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2671 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2674 2012-10-21 Glenn Morris <rgm@gnu.org>
2676 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2678 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2680 Port to OpenBSD 5.1.
2681 * frame.c (Fmouse_position, Fmouse_pixel_position):
2682 * xdisp.c (produce_stretch_glyph):
2683 Declare local vars only when they're needed.
2684 This is clearer and avoids a warning on OpenBSD about unused vars.
2685 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2686 This is safer, and avoids OpenBSD warnings about unused vars.
2687 * keyboard.c (record_menu_key): Remove unnecessary decl.
2688 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2689 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2690 as our definition clashes with OpenBSD's.
2691 * xfaces.c (load_face_colors, check_lface_attrs)
2692 (get_lface_attributes_no_remap, get_lface_attributes)
2693 (lface_fully_specified_p, x_supports_face_attributes_p)
2694 (tty_supports_face_attributes_p, face_fontset, realize_face)
2695 (realize_x_face, realize_tty_face):
2696 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2697 merely Lisp_Object *. This is more informative and avoids
2698 a warning on OpenBSD about accessing beyond an object's size.
2700 2012-10-20 Chong Yidong <cyd@gnu.org>
2702 * lread.c (Fload): Doc fix (Bug#12592).
2704 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2706 * font.c (Ffont_at): Fix previous change.
2708 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2710 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2711 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2714 * alloc.c (NSTATICS): Decrease to 0x800.
2716 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

2721 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2723 * nsterm.m (ns_select): Check writefds before call to
2724 FD_ISSET (Bug#12668).
2726 2012-10-18 Daniel Colascione <dancol@dancol.org>
2728 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2729 (staticpro): If we run out of staticpro slots, die with an
2730 informative error instead of just calling emacs_abort.
2732 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2734 Fix two flaws reported by Dmitry Antipov.
2735 * window.c (Ftemp_output_buffer_show): Remove.
2736 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
2737 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
2739 2012-10-17 Eli Zaretskii <eliz@gnu.org>
2741 * makefile.w32-in ($(BLD)/w32.$(O)):
2742 ($(BLD)/vm-limit.$(O)):
2744 ($(BLD)/unexw32.$(O)):
2745 ($(BLD)/fileio.$(O)):
2746 ($(BLD)/dispnew.$(O)): Update dependencies.
2748 * w32term.h (w32_initialize_display_info, initialize_w32_display):
2751 * w32proc.c: Include ctype.h.
2753 * w32.h (init_environment, check_windows_init_file)
2754 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
2755 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
2756 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
2757 (sys_link): Add prototypes.
2759 * w32.c: Include w32select.h.
2760 (sys_access, e_malloc, sys_select): Add prototypes.
2761 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
2763 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
2765 * unexw32.c: Include lisp.h and w32.h.
2767 * term.c [WINDOWSNT]: Include w32term.h.
2769 * process.c [WINDOWSNT]: Add prototype of sys_select.
2771 * fileio.c [WINDOWSNT]: Include w32.h.
2773 * dispnew.c [WINDOWSNT]: Include w32.h.
2775 * cygw32.c (Fcygwin_convert_path_to_windows)
2776 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
2777 Lisp_Object values. (Bug#12661)
2779 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
2780 to Lisp_Object. (Bug#12661)
2782 2012-10-17 Kenichi Handa <handa@gnu.org>
2784 * xdisp.c (reseat_1): Make the information stored in it->cmp_it
2787 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
2789 * buffer.c (Fkill_buffer): When unchaining the marker,
2790 reset its buffer pointer to NULL (Bug#12652).
2792 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
2794 Do not verify indirection counters of killed buffers (Bug#12579).
2795 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
2796 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
2798 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>

2831 * image.c (init_tiff_functions, init_imagemagick_functions)
2832 (init_svg_functions): Fix cygw32 build break by using these
2833 functions only when WINDOWSNT _and_ HAVE_NTGUI.

2854 Fix some stat-related races.
2855 * fileio.c (Fwrite_region): Avoid race condition if a file is
2856 removed or renamed by some other process immediately after Emacs
2857 writes it but before Emacs stats it. Do not assume that stat (or

2888 * fileio.c (check_existing): New function.
2889 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
2890 instead of calling 'stat', when what's needed is to check whether
2891 a file exists. This avoids expensive system calls on MS-Windows.
2894 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
2896 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

2987 * process.c (wait_reading_process_output):
2988 Use unsigned for counter where wraparound-on-overflow is desired,
2989 since unsigned is guaranteed to have that behavior and signed is not.
2990 (read_char): Use ptrdiff_t for string length.
2991 (get_input_pending): Remove first argument, since it was always
2992 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2993 and behave as if it had that value. Return new value of
2994 input_pending. All callers changed.
2995 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2996 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
2998 * keymap.c (push_key_description): Omit last arg, which was always 1.
2999 All callers changed.
3001 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
3003 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

3019 Don't include termopts.h.
3021 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3023 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3025 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3027 * commands.h (immediate_quit): Remove duplicate decl.
3029 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3031 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3034 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3036 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3038 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3039 match what GetLastError returns. Explain why the function is
3042 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3043 'is_tooltip_frame', to avoid confusion with its global namesake.
3045 2012-10-08 Daniel Colascione <dancol@dancol.org>
3047 * xdisp.c (start_hourglass): Call w32_note_current_window when
3048 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3049 build that caused Emacs to display the hourglass cursor forever.
3051 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3052 which is broken under remote desktop, calculate the number of
3053 colors available for a display based on the display's number of
3054 planes and number of bits per pixel per plane. (bug#10397).
3056 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3058 * nsfont.m (Vfonts_in_cache): New variable.
3059 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3060 are used. Add cached fonts to Vfonts_in_cache.
3061 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3063 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3065 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3067 (FONT_H): Define after FRAME_H.
3068 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3069 Update dependencies.
3071 * w32term.c: Remove leftover declaration of keyboard_codepage.
3073 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3075 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3076 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3077 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3078 (GLOBAL_SOURCES): Add cygw32.c.
3079 ($(BLD)/unexw32.$(O)):
3081 ($(BLD)/w32console.$(O)):
3082 ($(BLD)/w32fns.$(O)):
3083 ($(BLD)/w32heap.$(O)):
3084 ($(BLD)/w32menu.$(O)):
3085 ($(BLD)/w32proc.$(O)): Add w32common.h.
3087 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3089 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3091 2012-10-08 Daniel Colascione <dancol@dancol.org>
3093 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3094 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3095 accidental message numbering hole. Change other messages to
3098 * w32select.h (HAVE_W32SELECT): Remove.
3100 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3101 w32common.h instead of w32heap.h.
3103 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3104 (get_allocation_unit, get_processor_type, get_w32_major_version)
3105 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3106 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3107 (OS_NT, os_subtype, cache_system_info): Move declarations to
3110 * w32heap.c: Include w32common.h.
3111 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3112 (w32_minor_version, w32_build_number, w32_subtype):
3113 Remove duplicate definitions.
3115 * w32fns.c: Include w32common.h; include w32heap.h only in
3118 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3119 Use `report_file_error' instead of `error' in order to better
3120 inform users of what went wrong. Increase NTGUI_UNICODE file
3121 dialog box file name length to 32k, the maximum allowed by the NT
3124 * w32common.h: New file.
3125 (ROUND_UP, ROUND_DOWN, get_page_size)
3126 (get_allocation_unit, get_processor_type, get_w32_major_version)
3127 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3128 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3129 (OS_NT, os_subtype, cache_system_info): Move here.
3131 * unexw32.c, unexcw.c: Include w32common.h.
3133 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3134 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3135 to call syms_of_w32select.
3137 * cygw32.h: Remove obsolete EXFUN declarations.
3139 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

3142 of w32inevt.o from SOME_MACHINE_OBJECTS.
3144 2012-10-08 Daniel Colascione <dancol@dancol.org>
3146 * image.c: Permanent fix for JPEG compilation issue --- limit
3147 jpeglib `boolean' redefinition to Cygwin builds.
3149 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3151 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3153 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3156 2012-10-08 Daniel Colascione <dancol@dancol.org>
3158 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3159 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3160 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3161 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3162 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3163 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3164 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3165 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3166 now a supported configuration.
3168 * Makefile.in: consolidate image variables into LIBIMAGE; add
3169 W32_OBJ and W32_LIBS. Compile new files.
3172 (_DebPrint) declare tracing facility for W32 debugging. We need
3173 to unify tracing later.
3175 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3176 unconditional use of W32 Unicode functions. Cygwin runs only on
3177 100% Unicode operating systems.
3179 * cygw32.c: New file. Define Cygwin-specific facilities.
3180 (Fcygwin_convert_path_to_windows)
3181 (Fcygwin_convert_path_from_windows): New user functions for
3182 accessing Cygwin path-munging routines.
3184 * cygw32.h: New file.
3185 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3186 UTF-16LE strings temporarily inside non-Lisp-visible string
3189 (w32_strerror): Just what it says on the tin.
3191 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3192 also run for Cygwin; both systems have the same problem with using
3193 GUI facilities in a forked child. Also call syms_of_cygw32,
3194 syms_of_w32select in correct places.
3196 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3197 needs fork-then-exec for daemon launching.
3199 * font.h: Include frame.h.
3201 * image.c: Use the image library cache machinery only when we're
3202 compiling for native WINDOWSNT; Cygwin can use shared libraries
3203 like any other Unixlike system.
3205 * keyboard.c: Clarify a comment regarding the input loop.
3207 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3208 functions directly instead of trying to detect at runtime that our
3209 host operating system supports them. We make this change for two
3210 reasons: Cygwin lacks support for the multibyte character
3211 conversion functions used by the legacy menu code, and Cygwin
3212 never needs to rely on non-Unicode APIs.
3214 * unexw32.c (hinst): Declare extern.
3216 * w32.c: Change header order;
3217 (w32_strerror): Move to w32fns.c because we need it for
3218 non-WINDOWSNT builds.
3220 * w32.h: Add #error macro to make sure we don't include w32.h for
3221 Cygwin builds. Remove w32select declarations.
3223 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3224 w32fns.c. w32console.c is WINDOWSNT-only.
3226 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3227 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3229 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3230 (w32_major_version, w32_minor_version, w32_build_number)
3231 (os_subtype, sound_type): Define here
3232 (w32_defined_color): Make color parameter const for consistency
3233 with other _defined_color functions.
3234 (w32_createwindow): Unconditionally call w32_init_class instead of
3235 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3236 through the code is complex and unnecessary because class
3237 registration is practically free.
3238 (w32_name_of_message): New EMACSDEBUG-only function.
3239 (Fset_message_beep): Move here
3240 (Fx_open_connection): Require that the display name for Windows be
3241 "w32" for consistency, emacsclient disambiguation, and maybe, one
3242 day, multi-window-system support.
3243 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3244 Cygwin files for W32 GUI facilities, since these clearly don't
3245 expect Cygwin names.
3246 (_DebPrint): Define.
3247 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3248 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3249 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3250 (w32_last_error): Remove.
3252 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3254 * w32heap.c (syspage_mask): Declare here.
3255 (cache_system_info): Remove.
3257 * w32inevt.c (faked_key): Define globally, not statically.
3258 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3259 (w32_console_toggle_lock_key): Move to w32fns.c.
3261 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3263 * w32proc.c (_DebPrint): Move to w32fns.c.
3264 * w32select.c: Include string.h, stdio.h for Cygwin.
3265 * w32select.h: New File.
3267 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3269 (w32_message_fd): New variable. Under Cygwin, holds the file
3270 descriptor the system used to tell us about pending thread
3273 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3274 that prevented compilation under non-WINDOWSNT systems.
3276 (w32_initialize): Open /dev/windows and assign it to
3277 w32_message_fd. Provide w32 feature.
3279 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3280 (WM_EMACS_INPUT_READY): add.
3281 (prepend_msg, w32_message_fd): Declare globally.
3284 (keyboard_handle): Use only when WINDOWSNT.
3285 (notify_msg_ready): New function. Posts a message to the main
3286 thread's message queue under CYGWIN, which wakes up the main
3287 thread from select(2) by making the /dev/windows file descriptor
3288 ready. Under WINDOWSNT, it sets an event the same way the old
3291 (post, prepend_msg): Actually call notify_msg_ready instead of
3292 setting the input event directly.
3294 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3296 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3297 but it still has blocs in it, don't return it to the system,
3298 instead of aborting. (Bug#12402)
3300 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>

3335 Improve sys_siglist detection.
3336 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3337 defined as a macro, as is done in Solaris.
3338 (sys_siglist_entries): New macro.
3339 (save_strsignal): Use it.
3340 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3341 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3343 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3345 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3346 fullscreen/Fullscreen.
3348 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3349 tobar_height is new.
3351 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3352 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3353 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

3362 (canBecomeMainWindow): New function.
3364 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3366 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3368 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3370 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3372 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3373 that time stamps of directories could also be changed.
3374 Don't request the too broad GENERIC_WRITE, only the more restrictive
3375 FILE_WRITE_ATTRIBUTES access rights.
3377 * fileio.c (Fset_file_times): Special-case ignoring errors for
3378 directories only on MSDOS, not on MS-Windows.
3380 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3382 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3384 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3386 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3387 see whether CreateFile failed.
3389 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3391 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3392 to avoid similar races.
3393 * keyboard.c (pending_signals): Now bool, not int.
3395 Port timers to OpenBSD, plus check for timer failures.
3396 OpenBSD problem reported by Han Boetes.
3397 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3399 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3400 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3401 like OpenBSD, which has timer_settime but does not declare it.
3402 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3403 whether to use itimerspec-related primitives. All uses of
3404 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3406 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3408 * profiler.c (handle_profiler_signal): Fix a malloc race
3409 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3411 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3413 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3415 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3417 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3418 consistent with the change in return value of 'safe_strsignal'.
3420 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3422 Prefer plain 'static' to 'static inline' (Bug#12541).
3423 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3424 (bidi_set_sor_type, bidi_push_embedding_level)
3425 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

3430 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3431 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3432 Now 'static', not 'static inline'.
3434 Count overruns when profiling; change units to ns.
3435 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3436 Give extra weight to samples after overruns, to attempt to count
3437 the time more accurately.
3438 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3439 the underlying primitives nominally do ns.
3440 (Fprofiler_cpu_start): Document the change. Mention that
3441 the sampling intervals are only approximate.
3443 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3445 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3447 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3448 case for the special 0 coding-system.
3450 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3451 (Fmake_overlay): Remove redundant tests.
3452 (fix_start_end_in_overlays): Remove redundant recentering.
3454 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3456 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3457 Update dependencies.
3459 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3461 Fix a malloc race condition involving strsignal.
3462 A signal can arrive in the middle of a malloc, and Emacs's signal
3463 handler can invoke strsignal, which can invoke malloc, which is
3464 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3465 Fix it by altering the signal handler so that it does not invoke
3467 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3468 * process.c (status_message): Use const pointer, in case strsignal
3469 is #defined to safe_strsignal.
3470 * sysdep.c (sys_siglist, init_signals): Always define and
3471 initialize a substitute sys_siglist if the system does not define
3472 one, even if HAVE_STRSIGNAL.
3473 (safe_strsignal): Rename from strsignal. Always define,
3474 using sys_siglist. Return a const pointer.
3475 * syssignal.h (safe_strsignal): New decl.
3476 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3478 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3480 * w32proc.c (timer_loop): Fix code that waits for timer
3481 expiration, to avoid high CPU usage.
3483 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3485 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3486 (sweep_weak_table): Remove redundant prototypes.
3488 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3490 * emacs.c: Move the inclusion of TERM_HEADER after including
3491 windows.h on WINDOWSNT. This avoids compilation problems with
3494 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3496 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3497 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3498 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3499 as the previous version used 'void *'.
3501 * ralloc.c (ROUNDUP): Fix last change.
3502 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3505 * w32proc.c <disable_itimers>: New static flag.
3506 (init_timers): Initialize it to zero, after creating the critical
3507 sections used by the timer threads.
3508 (term_timers): Set to 1 before deleting the critical sections.
3509 (getitimer, setitimer): If disable_itimers is non-zero, return an
3510 error indication without doing anything. Reported by Fabrice
3511 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3512 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3514 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3517 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3518 term_ntproc after all the other bookkeeping, to get timers working
3519 as long as possible.
3521 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3523 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3524 Suggested by Juri Linkov in
3525 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3527 Prefer plain 'static' to 'static inline' (Bug#12541).
3528 With static functions, modern compilers inline pretty well by
3529 themselves; advice from programmers often hurts as much as it helps.
3530 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3531 this change shrinks the text size of the Emacs executable by 1.1%
3532 without affecting CPU significantly in my benchmark.
3533 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3612 (bidi_copy_it): Do the whole copy with a single memcpy.
3613 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3615 Revert the FOLLOW-SYMLINKS change for file-attributes.
3616 Doing it right would require several changes to Tramp, and there's
3617 not enough time to get that tested before the freeze today.
3618 * dired.c (directory_files_internal, Ffile_attributes):
3621 * frame.c (x_report_frame_params): Port better to wider ints.
3622 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3623 or that pointers can be printed in 15 decimal digits.
3624 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
3626 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>

3660 * vm-limit.c (lim_data): Now size_t.
3661 (check_memory_limits): Adjust prototypes of real_morecore and
3662 __morecore to receive argument of type ptrdiff_t. Use size_t for

3805 Suggested by Eli Zaretskii in
3806 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
3808 2012-09-30 Eli Zaretskii <eliz@gnu.org>
3810 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
3811 HAVE_TIMER_SETTIME is defined.

3815 Profiler improvements: more-accurate timers, overflow checks.
3816 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3817 signal.h, setjmp.h. Include systime.h instead.
3818 (saturated_add): New function.

3825 All uses changed to store the new value.
3826 (handle_profiler_signal): Rename from sigprof_handler_1,
3827 for consistency with other handlers. Do not check whether
3828 cpu_log is a hash-table if garbage collecting, since it
3829 doesn't matter in that case.

3831 for consistency with other handlers.
3832 (setup_cpu_timer): New function, with much of what used to be in
3833 Fprofiler_cpu_start. Check for out-of-range argument.
3834 Prefer timer_settime if available, and prefer
3835 thread cputime clocks, then process cputime clocks, then
3836 monotonic clocks, to the old realtime clock. Use make_timeval
3837 to round more-correctly when falling back to setitimer.
3838 (Fprofiler_cpu_start): Use it.
3839 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3840 Don't assume that passing NULL as the 2nd argument of setitimer

3843 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3844 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3845 non-fatal signal handlers. Ignore SIGPROF on startup.
3846 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3847 in profiler.c, since sysdep.c now uses it.
3849 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

3905 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3906 Since this stuff is now private to charset.c, there's no need for
3907 a public macro and no need to inline by hand.

3979 (sigaction): Rewrite to call sys_signal instead of duplicating its
3981 (sys_kill): Improve commentary.
3983 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3984 consistency with a signature of a signal handler. All callers
3986 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3987 install term_ntproc as a signal handler for SIGABRT, as that
3988 should be done by the dumped Emacs.
3990 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3992 * w32select.c (term_w32select): Protect against repeated
3993 invocation by setting clipboard_owner to NULL after calling

4111 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4112 fatal_error_backtrace.
4114 * w32proc.c (sys_kill): Undo last change: don't do anything when

4155 (init_tiff_functions, init_gif_functions, init_svg_functions):
4156 Arglist and w32_delayed_load calling convention changed.
4157 (gs_type): Remove init_gs_functions; there is no such function.
4158 (valid_image_p, make_image): Fix caller to lookup_image_type.
4160 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4162 Simplify and avoid signal-handling races (Bug#12471).
4164 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4165 Avoid recursive loop if there's a fatal error in the function itself.
4166 * atimer.c (pending_atimers):
4167 * blockinput.h: Don't include "atimer.h"; no longer needed.
4168 (interrupt_input_pending): Remove. All uses removed.
4169 pending_signals now counts both atimers and ordinary interrupts.
4170 This is less racy than having three separate pending-signal flags.
4171 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4173 Rename from their upper-case counterparts BLOCK_INPUT,
4174 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4175 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4176 This makes it easier to access volatile variables more accurately.
4177 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4178 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4179 that's more reliable if the code is buggy and sets
4180 interrupt_input_blocked to a negative value. All uses changed.
4181 * atimer.c (deliver_alarm_signal):
4182 Remove. No need to deliver this to the parent; any thread can
4183 handle this signal now. All uses replaced by underlying handler.
4184 * atimer.c (turn_on_atimers):
4185 * dispnew.c (handle_window_change_signal):
4186 * emacs.c (handle_danger_signal):
4187 * keyboard.c (kbd_buffer_get_event):
4188 Don't reestablish signal handler; not needed with sigaction.
4189 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4191 Rework to avoid unnecessary accesses to volatile variables.
4192 (UNBLOCK_INPUT_TO): Now a function.
4193 (totally_unblock_input, unblock_input): New decls.
4194 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4195 (init_data): Remove. Necessary stuff now done in init_signal.
4196 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4197 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4198 (fatal_error_code): Remove; no longer needed.
4199 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4200 it doesn't always backtrace. All uses changed. No need to reset
4201 signal to default, since sigaction and/or die does that for us now.
4202 Use emacs_raise (FOO), not kill (getpid (), FOO).
4203 (main): Check more-accurately whether we're dumping.
4204 Move fatal-error setup to sysdep.c
4205 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4206 * gtkutil.c (xg_get_file_name, xg_get_font):
4207 Remove no-longer-needed signal-mask manipulation.
4208 * keyboard.c, process.c (POLL_FOR_INPUT):
4209 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4210 * keyboard.c (read_avail_input): Remove.
4211 All uses replaced by gobble_input.
4212 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4213 (kbd_buffer_store_event_hold, gobble_input):
4214 (record_asynch_buffer_change) [USABLE_SIGIO]:
4215 (store_user_signal_events):
4216 No need to mess with signal mask.
4217 (gobble_input): If blocking input and there are terminals, simply
4218 set pending_signals to 1 and return. All hooks changed to not
4219 worry about whether input is blocked.
4220 (process_pending_signals): Clear pending_signals before processing
4221 them, in case a signal comes in while we're processing.
4222 By convention callers now test pending_signals before calling us.
4223 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4224 New functions, to support changes to blockinput.h.
4225 (handle_input_available_signal): Now extern.
4226 (reinvoke_input_signal): Remove. All uses replaced by
4228 (quit_count): Now volatile, since a signal handler uses it.
4229 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4230 All callers changed. Block SIGINT only if not already blocked.
4231 Clear sigmask reliably, even if Fsignal returns, which it can.
4232 Omit unnecessary accesses to volatile var.
4233 (quit_throw_to_read_char): No need to restore sigmask.
4234 * keyboard.c (gobble_input, handle_user_signal):
4235 * process.c (wait_reading_process_output):
4236 Call signal-handling code rather than killing ourselves.
4237 * lisp.h: Include <float.h>, for...
4238 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4239 (pending_signals): Now volatile.
4240 (syms_of_data): Now const if IEEE floating point.
4241 (handle_input_available_signal) [USABLE_SIGIO]:
4242 (terminate_due_to_signal, record_child_status_change): New decls.
4243 * process.c (create_process): Avoid disaster if memory is exhausted
4244 while we're processing a vfork, by tightening the critical section
4246 (send_process_frame, process_sent_to, handle_pipe_signal)
4247 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4249 (send_process): No need for setjmp/longjmp any more, since the
4250 SIGPIPE stuff is now gone. Instead, report an error if errno
4252 (record_child_status_change): Now extern. PID and W are now args.
4253 Return void, not bool. All callers changed.
4254 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4255 Remove. All uses removed. This bug should be fixed now in a
4257 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4258 and record the child status change directly. This avoids the
4259 need to futz with the signal mask.
4260 (process_fatal_action): Move here from emacs.c.
4261 (emacs_sigaction_flags): New function, containing
4262 much of what used to be in emacs_sigaction_init.
4263 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4264 caught by emacs, to make races less likely.
4265 (deliver_process_signal): Rename from handle_on_main_thread.
4267 (BACKTRACE_LIMIT_MAX): Now at top level.
4268 (thread_backtrace_buffer, threadback_backtrace_pointers):
4270 (deliver_thread_signal, deliver_fatal_thread_signal):
4271 New functions, for more-accurate delivery of thread-specific signals.
4272 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4273 (deliver_arith_signal): Handle in this thread, not
4274 in the main thread, since it's triggered by this thread.
4275 (maybe_fatal_sig): New function.
4276 (init_signals): New arg DUMPING so that we can be more accurate
4277 about whether we're dumping. Caller changed.
4278 Treat thread-specific signals differently from process-general signals.
4279 Block all signals while handling fatal error; that's safer.
4280 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4282 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4283 Ignore SIGPIPE unless batch.
4284 (emacs_backtrace): Output backtrace for the appropriate thread,
4285 which is not necessarily the main thread.
4286 * syssignal.h: Include <stdbool.h>.
4287 (emacs_raise): New macro.
4288 * xterm.c (x_connection_signal): Remove; no longer needed
4289 now that we use sigaction.
4290 (x_connection_closed): No need to mess with sigmask now.
4291 (x_initialize): No need to reset SIGPIPE handler here, since
4292 init_signals does this for us now.
4294 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4296 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4297 background rect may be larger (Bug#12245).
4299 2012-09-23 Chong Yidong <cyd@gnu.org>
4301 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4303 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4305 * .gdbinit: Just stop at fatal_error_backtrace.
4306 See Stefan Monnier's request in
4307 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4308 Remove no-longer-used query of system type.
4310 2012-09-22 Chong Yidong <cyd@gnu.org>
4312 * search.c (Freplace_match): Doc fix (Bug#12325).
4314 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4316 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4317 (Fline_end_position): Doc fix.
4319 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4321 2012-09-22 Chong Yidong <cyd@gnu.org>
4323 * dispextern.h (struct image_type): Add new slot, storing a type
4324 initialization function.
4326 * image.c (define_image_type): Call the image initializer function
4327 if it is defined. Arguments and return value changed.
4328 (valid_image_p, make_image): Callers changed.
4329 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4330 (gif_type, imagemagick_type, svg_type, gs_type):
4331 Add initialization functions.
4332 (Finit_image_library): Call lookup_image_type.
4333 (CHECK_LIB_AVAILABLE): Macro deleted.
4334 (lookup_image_type): Call define_image_type here, rather than via
4335 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4336 (syms_of_image): Move define_image_type calls for xbm_type and
4337 pbm_type to lookup_image_type.
4339 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4341 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4342 'idle_timers' from here ...
4343 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4344 lists, to avoid infloops when the timer does something stupid,
4345 like reinvoke itself with the same or smaller time-out.
4348 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4350 * window.c (Fsplit_window_internal): Handle only Qt value of
4351 Vwindow_combination_limit separately.
4352 (Qtemp_buffer_resize): New symbol.
4353 (Vwindow_combination_limit): New default value.
4356 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4358 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4359 the new overlay string. (Bug#10159)
4361 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4363 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4364 or that fprintf is async-signal-safe. POSIX doesn't require
4367 2012-09-22 Chong Yidong <cyd@gnu.org>
4369 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4372 2012-09-22 Kenichi Handa <handa@gnu.org>
4374 * composite.c (composition_reseat_it): Handle the case that a
4375 grapheme cluster is not covered by a single font (Bug#12352).
4377 2012-09-21 Chong Yidong <cyd@gnu.org>
4379 * image.c (define_image_type): Avoid adding duplicate types to
4380 image_types (Bug#12463). Suggested by Jörg Walter.
4382 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4384 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4385 (print_load_command_name): Add case LC_DATA_IN_CODE.
4386 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4388 2012-09-21 Glenn Morris <rgm@gnu.org>
4390 * eval.c (Frun_hook_with_args_until_success)
4391 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4393 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4395 * fileio.c (Ffile_selinux_context): Only call freecon when
4396 lgetfilecon succeeded.
4397 (Fset_file_selinux_context): Likewise. (Bug#12444)
4399 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4401 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4402 reordering, locate the cursor by calling set_cursor_from_row; if
4403 that fails, clear the desired glyph matrix before returning a
4404 failure indication to the caller. Fixes leaving garbled display
4405 when fast scrolling with a down-key. (Bug#12403)
4406 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4407 scrolling through multibyte text.
4409 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4411 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4412 calling mark_vectorlike since that's the one that marks the window.
4413 (mark_discard_killed_buffers): Mark the final cdr.
4414 * window.h (struct window): Move prev/next_buffers to the
4415 non-standard fields.
4416 * window.c (make_window): Initialize prev/next_buffers manually.
4418 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4420 Omit unused arg EXPECTED from socket hooks.
4421 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4422 * nsterm.m (ns_term_init):
4423 * termhooks.h (struct terminal.read_socket_hook):
4424 * w32inevt.c (w32_console_read_socket):
4425 * w32term.c (w32_read_socket):
4426 * xterm.c (XTread_socket):
4427 Omit unused arg EXPECTED. All callers changed.
4428 (store_user_signal_events): Return void, not int, since callers no
4429 longer care about the return value. All uses changed.
4431 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4433 * w32gui.h (XParseGeometry): Do not declare.
4435 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4437 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4438 Ignore 'expected'. See Eli Zaretskii in
4439 <http://bugs.gnu.org/12471#8> (last line).
4441 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4442 (XParseGeometry): Now static. Substitute extremal values for
4443 values that are out of range.
4445 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4447 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4449 * nsfns.m (XParseGeometry): Remove.
4450 (Fx_create_frame): Call x_set_offset to correctly interpret
4451 top_pos in geometry.
4453 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4454 (Fx_parse_geometry): If there is a space in string, call
4455 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4457 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4459 * search.c (scan_buffer): Use character positions in calls to
4460 region_cache_forward and region_cache_backward, not byte
4461 positions. (Bug#12196)
4463 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4464 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4466 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4467 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4468 emacs_blocked_malloc, now deleted.
4470 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4472 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4473 The workaround was for improving performance on Solaris 2.4, but
4474 is getting in the way now. Emacs will still work if someone is
4475 still running Solaris 2.4 in a museum somewhere; Sun dropped
4476 support for Solaris 2.4 in 2003.
4477 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4478 * process.c (create_process) [HAVE_WORKING_VFORK]:
4479 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4480 since Emacs no longer uses vfork on that platform.
4482 2012-09-17 Glenn Morris <rgm@gnu.org>
4484 * emacs.c: Use COPYRIGHT.
4486 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4488 Remove configure's --without-sync-input option (Bug#12450).
4489 When auditing signal-handling in preparation for cleaning it up,
4490 I found that SYNC_INPUT has race conditions and would be a real
4491 pain to fix. Since it's an undocumented and deprecated
4492 configure-time option, now seems like a good time to remove it.
4493 Also see <http://bugs.gnu.org/11080#16>.
4494 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4495 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4496 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4497 (malloc_hysteresis):
4498 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4499 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4500 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4501 (dont_register_blocks, bytes_used_when_reconsidered)
4502 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4503 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4504 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4505 Remove. All uses removed.
4506 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4507 implementation, one that depends on whether the new macro
4508 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4510 * atimer.c (run_timers, handle_alarm_signal):
4511 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4512 (handle_async_input, process_pending_signals)
4513 (handle_input_available_signal, init_keyboard):
4514 * nsterm.m (ns_read_socket):
4515 * process.c (wait_reading_process_output):
4516 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4517 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4519 * xterm.c (XTread_socket):
4521 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4522 * eval.c (handling_signal): Remove. All uses removed.
4523 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4524 All uses replaced with the SYNC_INPUT version.
4525 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4527 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4530 * font.c (Ffont_shape_gstring): Remove unused local.
4532 2012-09-16 Glenn Morris <rgm@gnu.org>
4534 * Makefile.in (clean): No longer run nextstep's clean.
4536 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4538 (ns-app): Move here from ns.mk, and simplify.
4539 (clean): Simplify nextstep entry.
4540 * ns.mk: Remove file.
4542 2012-09-17 Kenichi Handa <handa@gnu.org>
4544 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4545 not covert the last few charactes.
4547 2012-09-16 Kenichi Handa <handa@gnu.org>
4549 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4550 here, but just check the validity of glyphs in the glyph-string.
4552 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4554 * window.c (Fwindow_parameter, Fset_window_parameter):
4555 Accept any window as argument (Bug#12452).
4557 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4559 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4560 to ns_term_init to avoid memory leak.
4562 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4563 explicit retain/release.
4564 (ns_term_init): Only allow one display. Initialize outerpool and
4567 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4569 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4570 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4571 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4572 the Microsoft problem in a different way, by altering ../nt/config.nt.
4574 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4589 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4590 by lisp.h. This completes removal of setjmp.h inclusion
4591 erroneously announced in the previous commit. (Bug#12446)
4593 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4596 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4597 not defined as a macro. The latter happens on MS-Windows.
4600 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4602 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4603 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4604 Some instances of '#include <setjmp.h>' removed, if the
4605 only reason for the instance was because "lisp.h" was included.
4606 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4607 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4608 and _longjmp with the new symbols. Emacs already uses _setjmp if
4609 available, so this change affects only POSIXish hosts that have
4610 sigsetjmp but not _setjmp, such as some versions of Solaris and
4611 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4612 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4613 (png_load_body) [HAVE_PNG]:
4614 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4615 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4616 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4617 since PNG requires jmp_buf. This is the only exception to the
4618 general rule that we now use sys_setjmp and sys_longjmp.
4619 This exception is OK since this code does not change the signal
4620 mask or longjmp out of a signal handler.
4622 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4624 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4625 Include "syssignal.h", for 'main_thread'.
4627 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4629 Avoid out-of-range marker position (Bug#12426).
4630 * insdel.c (replace_range, replace_range_2):
4631 Adjust markers before overlays, as suggested by comments.
4632 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4633 Remove redundant check before calling offset_intervals.
4635 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4637 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4638 current buffer (Bug#12387).
4640 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4642 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4644 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4646 Use a more backwards-compatible timer format (Bug#12430).
4647 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4648 vector element, not from the 4th, since PSECS is now at the end.
4649 (Fcurrent_idle_time): Doc fix.
4651 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4653 Function to mark objects and remove killed buffers at once.
4654 * alloc.c (discard_killed_buffers): Rename to ...
4655 (mark_discard_killed buffers) ... new name. Add marking
4656 of remaining objects. Fix comment. Adjust users.
4657 (mark_object): Do not touch frame buffer lists here.
4658 * frame.c (delete_frame): Reset frame buffer lists here.
4660 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4662 Better workaround for GNOME bug when --enable-gcc-warnings.
4663 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4664 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4665 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4667 Simplify SIGIO usage (Bug#12408).
4668 The code that dealt with SIGIO was crufty and confusing, e.g., it
4669 played tricks like "#undef SIGIO" but these tricks were not used
4670 consistently. Simplify mostly by not #undeffing standard symbols,
4671 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4672 or not as we please) rather than "defined SIGIO" (standard symbol
4673 that we probably shouldn't #undef).
4674 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4675 Modules that need it can include it.
4676 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4677 * dispextern.h (ignore_sigio): New decl.
4678 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4679 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4680 * emacs.c (shut_down_emacs):
4681 * keyboard.c (kbd_buffer_store_event_hold):
4682 Use ignore_sigio rather than invoking 'signal' directly.
4683 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4685 (FIONREAD, SIGIO): Do not #undef.
4686 (tty_read_avail_input): Use #error rather than a syntax error.
4687 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4688 for I_PIPE, used by SETUP_SLAVE_PTY.
4689 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4690 * sysdep.c (croak): Remove; no longer needed. This bit of
4691 temporary code, with Fred N. Fish's comment that it's temporary,
4692 has been in Emacs since at least 1992!
4693 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4694 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4695 * syssignal.h (croak): Remove decl.
4696 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4697 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4698 now that we're termios-only.
4699 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4700 * term.c (dissociate_if_controlling_tty): Use #error rather than
4703 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4704 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4705 to work around GNOME bug 683906.
4706 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4707 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4708 This works around GCC bug 54561.
4710 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4712 More fixes for 'volatile' and setjmp/longjmp.
4713 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4714 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4715 (png_load_body) [HAVE_PNG]:
4716 (jpeg_load_body) [HAVE_JPEG]:
4717 New function, with most of the old parent function's body.
4718 (png_load) [HAVE_PNG]:
4719 (jpeg_load) [HAVE_JPEG]:
4720 Invoke the new function, to avoid longjmp munging our locals.
4721 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4722 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4723 longjmp is passed 2, as the C standard doesn't guarantee this.
4724 Instead, store the failure code into mgr->failure_code.
4726 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4728 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4729 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4730 (syms_of_keyboard): Remove support for unread-command-char.
4732 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4734 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4735 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4736 violation. (Bug#12426)
4738 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4740 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4742 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4744 * eval.c: Add `inhibit-debugger'.
4745 (Qinhibit_debugger): New symbol.
4746 (call_debugger): Bind it instead of Qdebug_on_error.
4747 (maybe_call_debugger): Test Vinhibit_debugger.
4748 (syms_of_eval): Define inhibit-debugger.
4749 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4750 (syms_of_xdisp): Remove inhibit-debug-on-message.
4752 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4754 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4755 If a nonvolatile local variable is written before a _longjmp to
4756 the frame containing the variable, and is read after the _longjmp,
4757 the value read is indeterminate. Some local variables of type
4758 'struct handler' and 'struct catchtag' are used in this way, so
4759 mark each of their slots as volatile if the slot can be set before
4760 _longjmp and read afterwards.
4761 * lisp.h (struct handler): var and chosen_clause are now volatile.
4762 (struct catchtag): val, next, and pdlcount are now volatile.
4764 * bidi.c (bidi_push_it, bidi_pop_it):
4765 * fns.c (copy_hash_table):
4766 * image.c (define_image_type):
4767 * keyboard.c (kbd_buffer_store_event_hold):
4768 * process.c (Fprocess_send_eof):
4769 * xfaces.c (x_create_gc) [HAVE_NS]:
4770 * xgselect.c (xg_select):
4771 Prefer assignment to memcpy when either will do.
4773 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4774 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4775 time an item is removed. No need to mark this function 'inline';
4776 the compiler knows better than we do.
4778 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4780 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4781 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4782 to change_frame_size (Bug#12388).
4783 (windowDidResize:): Pass YES to updateFrameSize.
4785 * nsterm.h: Add delay parameter to updateFrameSize.
4787 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4789 Discard killed buffers from deleted window and frame objects.
4790 This reduces an amount of references to killed buffers and
4791 helps GC to reclaim them faster.
4792 * alloc.c (discard_killed_buffers): New function.
4793 (mark_object): Use it for deleted windows and frames.
4794 (mark_object): If symbol's value is set up for a killed buffer
4795 or deleted frame, restore its global binding.
4796 * data.c (swap_in_global_binding): Add GC notice.
4797 (swap_in_symval_forwarding): Use convenient set_blv_where.
4798 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4799 * window.h: ... to here.
4801 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4803 Convenient macro to check whether the buffer is live.
4804 * buffer.h (BUFFER_LIVE_P): New macro.
4805 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4806 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4808 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4810 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4811 composition cases (Bug#12364).
4813 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4814 overhang of succeeding glyphs overlapping box cursor.
4816 * w32term.c (x_draw_glyph_string): Likewise.
4818 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4820 Simplify, document, and port floating-point (Bug#12381).
4821 The porting part of this patch fixes bugs on non-IEEE platforms
4822 with frexp, ldexp, logb.
4823 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4825 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4826 support, by removing commented-out code and briefly listing the
4827 C89 functions excluded. The commented-out stuff was confusing
4828 maintenance, e.g., we thought we needed cbrt but it was commented out.
4829 (logb): Remove decl; no longer needed.
4830 (isfinite): New macro, if not already supplied.
4831 (isnan): Don't replace any existing macro.
4832 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4833 are present on all C89 platforms.
4834 (Ffrexp): Do not special-case zero, as frexp does the right thing
4836 (Flogb): Do not use logb, as it doesn't have the desired meaning
4837 on hosts that use non-base-2 floating point. Instead, stick with
4838 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4839 frexp, to avoid getting an unspecified result.
4841 * xdisp.c (Qinhibit_debug_on_message): Now static.
4843 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4845 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4846 NSBezierPath (Bug#12131).
4848 2012-09-10 Chong Yidong <cyd@gnu.org>
4850 * fns.c (Fdelq, Fdelete): Doc fix.
4852 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4854 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4855 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4857 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4859 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4860 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4863 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4865 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4866 left fringe if the window has a left margin. This avoids leaving
4867 traces of the cursor because its leftmost pixel is not drawn over.
4869 * dispnew.c (update_window_line): When the left margin area of a
4870 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4871 that screen line. (Bug#12277)
4873 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4875 Assume C89 or later for math functions (Bug#12381).
4876 This simplifies the code, and makes it a bit smaller and faster,
4877 and (most important) makes it easier to clean up signal handling
4878 since we can stop worring about floating-point exceptions in
4879 library code. That was a problem before C89, but the problem
4880 went away many years ago on all practical Emacs targets.
4881 * data.c, image.c, lread.c, print.c:
4882 Don't include <math.h>; no longer needed.
4883 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4884 might be autoconfigured, as that never happens.
4886 * doprnt.c (DBL_MAX_10_EXP):
4887 * print.c (DBL_DIG):
4888 Remove. C89 or later always defines these.
4889 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4890 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4891 (arith_error, domain_error, domain_error2):
4892 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4893 no longer needed -- we simply return what C returns. All uses removed.
4894 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4896 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4897 Remove. All uses expanded, as these macros are no longer used
4898 more than once and are now more trouble than they're worth.
4899 (Ftan): Use tan, not sin / cos.
4900 (Flogb): Assume C89 frexp.
4901 (fmod_float): Assume C89 fmod.
4902 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4903 (init_floatfns): Remove. All uses removed.
4905 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4907 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4908 compositeToPoint for OSX < 10.6 (Bug#12390).
4910 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4912 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4913 This produces more-accurate results.
4915 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4917 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4918 changes (Bug#12088).
4920 2012-09-08 Chong Yidong <cyd@gnu.org>
4922 * syntax.c (Fstring_to_syntax): Doc fix.
4924 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4926 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4927 in the internal border.
4928 (x_set_window_size): Remove static variables and their usage.
4929 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4930 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4931 Remove fringe/internal border adjustment (Bug#11052).
4932 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4933 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4934 (ns_fix_rect_ibw): Remove.
4935 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4936 (ns_dumpglyphs_box_or_relief): Ditto.
4937 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4939 (ns_dumpglyphs_image): Ditto.
4940 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4942 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4943 their usage. Add fringe_extended_p and its use as in other terms.
4944 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4945 scroll bar was removed.
4946 (updateFrameSize): New function.
4947 (windowDidResize): Move code to updateFrameSize and call it.
4949 * nsterm.h (EmacsView): Add updateFrameSize.
4951 2012-09-07 Chong Yidong <cyd@gnu.org>
4953 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4955 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4957 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4959 More signal-handler cleanup (Bug#12327).
4960 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4961 Problem introduced when merging patches. Noted by Eli Zaretskii in
4962 <http://bugs.gnu.org/12327#67>.
4963 * floatfns.c: Comment fix.
4964 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4965 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4966 and anyway the declaration is harmless even if SIGDANGER is not defined.
4967 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4968 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4969 source files not surprisingly expected syssignal.h to define, or
4970 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4971 Include <sys/ioctl.h>, for FIONREAD.
4972 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4973 This eliminates a problem whereby other files mysteriously had
4974 to include "syssignal.h" before including "systty.h" if they
4975 wanted to use "#ifdef SIGIO".
4977 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4979 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4981 * w32.c (sigemptyset): Empty the set.
4982 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4984 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4986 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4988 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4989 (mark_object): Likewise for frame objects.
4991 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4993 * syssignal.h (handle_on_main_thread): Always declare,
4994 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4995 This ports to platforms without HAVE_PTHREAD.
4997 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4999 Signal-handler cleanup (Bug#12327).
5000 Emacs's signal handlers were written in the old 4.2BSD style with
5001 sigblock and sigmask and so forth, and this led to some
5002 inefficiencies and confusion. Rewrite these to use
5003 pthread_sigmask etc. without copying signal sets around. Also,
5004 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5005 'signal', and instead use functions that do not attempt to take
5006 over the system name space. This patch causes Emacs's text
5007 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5008 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5009 Do not include <signal.h> or "syssignal.h", as these
5010 modules do not use signals.
5011 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5012 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5013 Do not include <signal.h>, as "syssignal.h" does that for us now.
5014 * atimer.c (sigmask_atimers): New function.
5015 (block_atimers, unblock_atimers): New functions,
5016 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5018 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5019 no longer needed here.
5020 * emacs.c (main): Inspect existing signal handler with sigaction,
5021 so that there's no need to block and unblock SIGHUP.
5022 * sysdep.c (struct save_signal): New member 'action', replacing
5023 old member 'handler'.
5024 (save_signal_handlers, restore_signal_handlers):
5025 Use sigaction instead of 'signal' to save and restore.
5026 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5027 New function. All users of 'signal' modified to use set_sighandler
5028 if they're writeonly, and to use sys_signal if they're read+write.
5029 (emacs_sigaction_init, forwarded_signal): New functions.
5030 (sys_signal): Remove. All uses replaced by calls to sigaction
5031 and emacs_sigaction_init, or by direct calls to 'signal'.
5032 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5033 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5034 all uses replaced by pthread_sigmask etc. calls.
5035 * syssignal.h: Include <signal.h>.
5036 (emacs_sigaction_init, forwarded_signal): New decls.
5037 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5038 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5039 (sigmask, sys_sigmask): Remove; no longer needed.
5040 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5041 (sigblock, sigunblock, sigfree):
5042 (sigsetmask) [!defined sigsetmask]:
5043 Remove. All uses replaced by pthread_sigmask.
5044 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5045 no longer need to be replaced, and its typical old uses
5046 are now done via emacs_sigaction_init and sigaction.
5047 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5048 (sys_sigdel): Remove; unused.
5049 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5051 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5053 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5054 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5056 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5058 Explicitly mark buffer_defaults and buffer_local_symbols.
5059 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5060 mark_local_symbols here.
5061 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5062 since special buffers aren't marked here any more.
5063 (allocate_buffer): Chain new buffer with all_buffers here...
5064 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5066 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5067 (syms_of_buffer): Remove staticpro of the above.
5068 (init_buffer_once): Set names for buffer_defaults and
5069 buffer_local_symbols.
5071 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5073 Use bool for booleans in font-related modules.
5074 * font.c (font_intern_prop, font_style_to_value)
5075 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5076 (generate_otf_features, font_check_otf_features, font_check_otf)
5077 (font_match_p, font_list_entities, font_at):
5078 * fontset.c (fontset_id_valid_p, reorder_font_vector
5079 (fontset_find_font, Fset_fontset_font)
5080 (face_suitable_for_char_p) [0]:
5081 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5082 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5083 (m17n_flt_initialized, ftfont_shape_by_flt):
5084 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5085 * nsfont.m (nsfont_draw):
5086 * w32font.c (w32font_draw):
5087 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5088 Use bool for booleans.
5089 * font.h: Adjust to above API changes.
5090 (struct font, struct font_driver, struct font_driver_list):
5091 Use bool for booleans.
5092 (struct font): Remove useless member encoding_type.
5094 * fontset.c, xftfont.c: Omit unnecessary static decls.
5096 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5098 * alloc.c (mark_object): Revert window marking code
5099 since it's unsafe for the Fset_window_configuration.
5101 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5103 Fix race conditions with signal handlers and errno (Bug#12327).
5104 Be more systematic about preserving errno whenever a signal
5105 handler returns, even if it's not in the main thread. Do this by
5106 renaming signal handlers to distinguish between signal delivery
5107 and signal handling. All uses changed.
5108 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5109 * data.c (deliver_arith_signal): Rename from arith_error.
5110 * dispnew.c (deliver_window_change_signal): Rename from
5111 window_change_signal.
5112 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5113 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5114 * keyboard.c (deliver_input_available_signal): Rename from
5115 input_available_signal.
5116 (deliver_user_signal): Rename from handle_user_signal.
5117 (deliver_interrupt_signal): Rename from interrupt_signal.
5118 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5119 (deliver_child_signal): Rename from sigchld_handler.
5120 * atimer.c (handle_alarm_signal):
5121 * data.c (handle_arith_signal):
5122 * dispnew.c (handle_window_change_signal):
5123 * emacs.c (handle_fatal_signal, handle_danger_signal):
5124 * keyboard.c (handle_input_available_signal):
5125 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5126 * process.c (handle_pipe_signal, handle_child_signal):
5127 New functions, with the actual signal-handling code taken from the
5128 original respective signal handlers, sans the sporadic attempts to
5129 preserve errno, since that's now done by handle_on_main_thread.
5130 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5131 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5132 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5134 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5135 Move initialization of main_thread to sysdep.c's init_signals.
5136 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5137 our usage, and simplifies the mainline code.
5138 (record_child_status_change): New static function, as a helper
5139 for handle_child_signal, and with most of the old child handler's
5141 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5142 (handle_child_signal): Use the above.
5143 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5144 Moved here from emacs.c.
5145 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5146 code moved here from emacs.c's main function.
5147 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5148 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5149 This lets callers save and restore errno properly.
5151 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5153 Remove redundant or unused things here and there.
5154 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5155 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5156 * editfns.c (Fcompare_buffer_substrings): Likewise.
5157 * frame.h (struct terminal, struct font_driver_list):
5158 Remove redundant declarations.
5159 * window.h (Qleft, Qright): Likewise.
5161 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5163 Do not mark objects from deleted buffers, windows and frames.
5164 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5165 (mark_object): Likewise for windows and frames.
5167 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5169 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5170 buffer_defaults and buffer_local_symbols as valid objects.
5171 Return special value to denote them.
5173 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5175 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5176 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5177 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5178 (file_name_absolute_p, Fsubstitute_in_file_name):
5179 (check_executable, check_writable, Ffile_accessible_directory_p)
5180 (Fset_file_selinux_context, Fdefault_file_modes)
5181 (Finsert_file_contents, choose_write_coding_system)
5182 (Fwrite_region, build_annotations, a_write, e_write)
5184 * filelock.c (boot_time_initialized, get_boot_time)
5185 (get_boot_time_1, lock_file_1, within_one_second):
5186 * floatfns.c (in_float):
5187 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5188 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5189 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5190 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5191 * window.c (compare_window_configurations):
5192 Use bool for booleans.
5193 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5194 (Fdefault_file_modes): Now mode_t, not int, for modes.
5195 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5196 (internal_delete_file): Now returns void, not a (boolean) int,
5197 since nobody was looking at the return value.
5198 * lisp.h, window.h: Adjust to above API changes.
5200 * xdisp.c (set_message): Simplify and reindent last change.
5202 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5204 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5206 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5208 * eval.c (call_debugger): Make the function non-static so that we
5209 can call it from set_message.
5211 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5212 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5214 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5216 Give more-useful info on a fatal error (Bug#12328).
5217 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5218 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5219 of doing the work ourselves.
5220 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5221 do most of the work.
5222 (fatal_error_backtrace): New function, taken from the guts
5223 of the old fatal_error_signal, but with a new option to output
5225 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5226 info about the signal than just its number.
5227 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5228 * sysdep.c: Include <execinfo.h>
5229 (emacs_backtrace): New function, taken partly from the previous
5230 code of the 'die' function.
5231 (emacs_abort): Call fatal_error_backtrace rather than abort.
5233 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5235 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5236 eager (load-time) macro-expansion.
5237 * lisp.mk (lisp): Add macroexp.
5239 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5241 Simplify redefinition of 'abort' (Bug#12316).
5242 Do not try to redefine the 'abort' function. Instead, redo
5243 the code so that it calls 'emacs_abort' rather than 'abort'.
5244 This removes the need for the NO_ABORT configure-time macro
5245 and makes it easier to change the abort code to do a backtrace.
5246 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5247 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5248 Remove; sysdep.c's emacs_abort now takes its place.
5249 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5250 'abort' changed to use 'emacs_abort'.
5251 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5252 (abort) [!defined abort]: Rename to ...
5253 (emacs_abort): ... new name.
5254 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5255 the place of the old 'abort' in emacs.c.
5256 * w32.c, w32fns.c (abort): Do not #undef.
5257 * w32.c (emacs_abort): Rename from w32_abort.
5259 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5261 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5262 offsets[j].dv, since the y axis of the screen coordinates points
5263 down, while the y axis of the font definition coordinates points
5264 up. This fixes display of Arabic diacritics such as KASRA and
5265 KASRATAN. (Bug#11860)
5267 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5269 Be more systematic about _setjmp vs setjmp.
5270 * alloc.c (test_setjmp, mark_stack):
5271 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5272 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5273 (png_load, my_error_exit, jpeg_load):
5274 * process.c (send_process_trap, send_process):
5275 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5276 The underscored versions are up to 30x faster on some hosts.
5277 Formerly, the code used setjmp+longjmp sometimes and
5278 _setjmp+_longjmp at other times, with no particular reason to
5279 prefer setjmp+longjmp.
5281 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5283 Fix minor problem found by static checking.
5284 * buffer.c (Fdelete_all_overlays): Return nil.
5286 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5288 * buffer.c (Fdelete_all_overlays): New function.
5290 2012-09-03 Chong Yidong <cyd@gnu.org>
5292 * gtkutil.c: Add extern decl for Qxft.
5294 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5296 * emacs.c, eval.c: Use bool for boolean.
5297 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5298 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5299 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5300 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5301 (main, decode_env_path, Fdaemon_initialized):
5302 * eval.c (call_debugger, Finteractive_p, interactive_p):
5303 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5304 (maybe_call_debugger, Fbacktrace):
5305 * process.c (read_process_output, exec_sentinel):
5306 Use bool for booleans.
5307 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5308 All callers changed.
5309 * eval.c (interactive_p): Omit always-true boolean argument
5310 EXCLUDE_SUBRS_P. All callers changed.
5311 * dispextern.h, lisp.h: Reflect above API changes.
5312 * firstfile.c (dummy): Use the address of 'main', whose signature
5313 won't change, instead of the address of 'initialize', whose
5314 signature just changed from int to bool.
5315 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5316 * msdos.c (fatal_error_in_progress): ... from here.
5317 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5319 (redisplay_internal, unwind_redisplay): Simply clear
5320 REDISPLAYING_P when unwinding, instead of saving its previous,
5321 always-false value and then restoring it.
5323 Clean up some extern decls.
5324 Mostly, this hoists extern decls out of .c files and into .h files.
5325 That way, we're more likely to catch errors if the interfaces change.
5326 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5327 declare xg_mark_data.
5328 * dispextern.h (x_frame_parm_handlers):
5330 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5331 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5332 (Qultra_bold, Qoblique, Qitalic):
5333 Move extern decl here from .c file.
5334 * alloc.c (xg_mark_data) [USE_GTK]:
5336 * eval.c (Qlexical_binding):
5337 * fns.c (time) [!HAVE_UNISTD_H]:

5343 * process.c (QCfamily, QCfilter):
5344 * widget.c (free_frame_faces):
5345 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5346 * xfont.c (x_clear_errors):
5347 * xterm.c (x_frame_parm_handlers):
5348 Remove now-redundant extern decls.
5349 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5350 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5352 * xfaces.c: Remove unnecessary static decls.
5353 * xterm.c (updating_frame): Remove decl of nonexistent object.
5355 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5356 when building globals.h, as the objects that are not built on
5357 this host are not needed to compile C files on this host.
5359 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5361 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5363 * frame.h: Add missing prototype for x_wm_set_size_hint.
5365 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5367 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.

5369 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
5370 (Fsubstitute_command_keys):

5372 (save_excursion_save, save_excursion_restore)
5373 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
5374 (format_time_string, general_insert_function)
5375 (make_buffer_string, make_buffer_string_both)
5376 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
5377 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

5388 (set_intervals_multibyte_1, set_intervals_multibyte):
5389 * keyboard.c (decode_timer):
5390 Use bool for boolean.
5391 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5392 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5394 2012-09-02 Chong Yidong <cyd@gnu.org>
5396 * keymap.c (push_key_description): Print M-TAB as C-M-i
5399 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5401 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5402 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

5407 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5409 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5411 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5412 more than one grapheme cluster passed to the shaper: compute the
5413 offset adjustment values separately for each cluster. (Bug#11860)
5415 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5416 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5417 about implicit conversions from integer to pointer.
5419 2012-09-01 Daniel Colascione <dancol@dancol.org>
5421 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5422 system used too early.
5424 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5426 Better seed support for (random).
5427 * emacs.c (main): Call init_random.
5428 * fns.c (Frandom): Set the seed from a string argument, if given.
5429 Remove long-obsolete Gentzel cruft.
5430 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
5431 (init_random): New function.
5433 2012-09-01 Daniel Colascione <dancol@dancol.org>
5435 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
5436 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
5437 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
5438 x_wm_set_size_hint, x_query_colors, x_real_positions,
5439 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
5440 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
5441 all of which have been moved to common code.
5443 * xfaces.c: Include TERM_HEADER instead of listing all possible
5444 window-system headers.
5446 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
5449 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
5450 directly accessing frame internals.
5452 * w32font.h: Include font.h. Define syms_of_w32font and
5455 * process.c: Include TERM_HEADER instead of listing all possible
5456 window-system headers.
5458 * nsterm.h: Remove declarations now in frame.h.
5459 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
5461 * menu.c: Include TERM_HEADER instead of listing all possible
5462 window-system headers.
5464 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
5467 * keyboard.c: Include TERM_HEADER instead of listing all possible
5468 window-system headers.
5470 * image.c: Include TERM_HEADER instead of listing all possible
5471 window-system headers. Declare Vlibrary_cache when compiling for
5474 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
5475 window system declarations.
5477 * frame.h: Move common functions here: set_frame_menubar,
5478 x_set_window_size, x_sync, x_get_focus_frame,

5507 * lisp.h (mark_ttys): Remove prototype.
5508 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

5531 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
5532 does not become zero (Bug#12234).
5534 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>

5542 source directory's site-lisp dir to the load-path if it exists,
5543 consistent with in-tree builds. (Bug#12302)
5545 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5547 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

5562 (timeout_handler:): Set timer_fired to YES.
5563 (runDialogAt:): Set timer_fired to NO.
5564 Handle click on close button as quit.
5566 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5567 Add window_closed and button_values. Add void as return value for
5568 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5569 Add process_dialog as new member.
5571 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5573 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5709 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5710 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5711 not a boolean 'int', since callers never look at the return value.

5713 * coding.h (decoding_buffer_size, encoding_buffer_size)
5714 (emacs_mule_string_char): Remove unused extern decls.
5715 (struct iso_2022_spec, struct coding_system):

5723 Fix spare memory change (Bug#12286).
5724 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5725 (valid_lisp_object_p): Likewise.
5727 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5729 * window.c (Fset_window_configuration): Record any window's old
5730 buffer if it's replaced (see Bug#8789). If the new current
5731 buffer doesn't appear in the selected window, go to its old
5734 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5736 Special MEM_TYPE_SPARE to denote reserved memory.
5737 * alloc.c (enum mem_type): New memory type.
5738 (refill_memory_reserve): Use new type for spare memory.
5739 This prevents live_cons_p and live_string_p from incorrect

5742 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5745 * Makefile.in (.PHONY): versioclean -> versionclean.

5748 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5749 * window.c (Qwindow_valid_p, decode_valid_window):
5750 Now static, not extern.
5751 * data.c (Qinterval): Remove; unused.

5768 (map_sub_char_table):
5769 Use bool for boolean.
5770 * character.c (str_to_unibyte): Omit last boolean argument; it was
5771 always 0. All callers changed.
5772 * character.h, charset.h: Adjust to match previous changes.
5773 * character.h (char_printable_p): Remove decl of nonexistent function.
5774 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5775 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5776 are all boolean, so make them single-bit bitfields.
5778 * lisp.h (ASET): Remove attempt to detect side effects.
5779 It was meant to be temporary and it often doesn't work,
5780 because when IDX has side effects the behavior of IDX==IDX
5781 is undefined. See Stefan Monnier in
5782 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5784 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5786 * lisp.h (functionp): New function (extracted from Ffunctionp).
5787 (FUNCTIONP): Use it.
5788 * eval.c (Ffunctionp): Use it.
5790 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5792 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5793 as that's faster and simpler than static storage. Don't bother
5794 with the g_main_context_query overhead if g_main_context_pending
5795 says no events are pending.
5796 (gfds, gfds_size): Remove these static vars.
5797 (xgselect_initialize): Remove; no longer needed.
5798 All uses and decls removed.
5800 * emacs.c (fatal_error_signal_hook): Remove.
5801 All uses removed. This leftover from old code was always 0.
5803 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5804 * casefiddle.c (casify_object, casify_region):
5805 * casetab.c (set_case_table):

5816 On assertion failure, print backtrace if available.
5817 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.

5828 Use bool for booleans, instead of int.
5829 * lisp.h, process.h: Adjust prototypes to match above changes.
5830 * callint.c (Fcall_interactively): Don't assume the mark's
5831 offset fits in 'int'.

5843 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5844 Use bool for booleans, instead of int.
5845 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5846 since the 1-or-0 return value is always ignored anyway.
5847 (mmap_initialized_p):
5848 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5849 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5851 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5853 * bidi.c: Use bool for boolean.
5854 This is a bit more readable, and makes the text segment of bidi.o
5855 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5856 Presumably it's faster too.

5890 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5892 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5893 Otherwise, the compiler complains about (A?B:C) where B is void
5894 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5895 (fontset_add): Return void, for FONTSET_ADD.
5897 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>

5922 * xdisp.c (push_message):
5923 Use bool for booleans affected directly or indirectly by
5926 Make recently-introduced setters macros.
5927 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5928 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5929 (set_fontset_default, set_fontset_fallback): Rename from their
5930 upper-case counterparts, and make them functions rather than macros.
5931 This is more consistent with the other recently-introduced setters.
5932 These don't need to be inline, since they're local.
5934 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5936 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in

5939 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5941 * lisp.h (vcopy): Use memcpy rather than our own loop.
5942 This fixes a performance regression introduced by the recent
5943 addition of vcopy. This means 'vcopy' will need to be modified
5944 for a copying collector, but that's OK. Also, tighten the
5945 checking in the assertion.
5947 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5949 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5950 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5951 non-base glyph for the width of the base character, according to
5952 what x_draw_composite_glyph_string_foreground expects.
5953 Generate WADJUST value according to composition_gstring_width's
5954 expectations, to produce correct width of the composed character.
5955 Reverse the sign of the DU offset produced by ScriptPlace.
5957 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5959 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5961 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5963 Avoid direct writes to contents member of struct Lisp_Vector.
5964 * lisp.h (vcopy): New function to copy data into vector.

5980 buffer to the specified position.
5982 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>

5985 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5986 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5987 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5990 2012-08-20 Glenn Morris <rgm@gnu.org>
5992 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5993 Don't assume that `ln -f' works.
5995 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5997 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5998 and later about non-assignments with no effect. See discussion at
5999 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6002 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6004 Inline setter functions for Lisp_Objects slots of struct specbinding.
6005 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6008 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6010 * window.c (select_window): Always make selected window's buffer
6013 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>

6016 * category.h (CATEGORY_DOCSTRING): Use AREF.
6017 (SET_CATEGORY_DOCSTRING): Use ASET.
6018 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6020 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6022 Inline setter functions for hash table members.
6023 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6024 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6025 (set_hash_key_and_value, set_hash_index, set_hash_next)
6026 (set_hash_hash): New functions.
6027 * charset.c, fns.c: Adjust users.
6029 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6031 Inline getter and setter functions for per-buffer values.

6035 * buffer.c, data.c: Adjust users.
6037 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6039 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6041 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6043 Rely on <config.h> + <unistd.h> to declare 'environ',
6044 as gnulib does this if the system doesn't.
6045 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6046 Remove declaration. MS-Windows declares it on stdlib.h which is
6047 included by conf_post.h.
6048 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6049 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6050 * vm-limit.c: Include <unistd.h>, for 'environ'.
6052 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6053 (start_of_data): Remove decl; mem-limits.h provides it.
6055 * xdisp.c (handle_invisible_prop): Make it a bit faster
6056 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6058 2012-08-19 Chong Yidong <cyd@gnu.org>
6060 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6063 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>

6068 * data.c (set_internal): Don't use set_blv_found.
6069 (Fkill_local_variable): Likewise.
6071 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6073 * nsfont.m (ns_ascii_average_width): Ensure the string
6074 ascii_printable is initialized with a null-terminated character
6075 array. Otherwise, it can contain undesired extra characters.
6077 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6079 port new setting code to Sun C 5.8 2005/10/13
6080 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6081 Return void, not Lisp_Object. Otherwise, the compiler
6082 complains about (A?B:C) where B is void and C is Lisp_Object
6083 when compiling CHAR_TABLE_SET, due to the recent change to
6084 the API of sub_char_table_set_contents.
6086 2012-08-18 Chong Yidong <cyd@gnu.org>
6088 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

6259 directly-specified attributes.
6260 (merge_face_ref): Recognize :font.
6262 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

6309 Use C-locale tests instead of locale-specific tests for character
6310 types, since we want the ASCII interpretation here, not the
6311 interpretation suitable for whatever happens to be the current locale.

6916 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6917 * w32.c (init_environment): Change the default values of many
6918 environment variables in dflt_envvars[] to NULL, to avoid pushing
6919 them into environment when they were not already defined.
6920 Remove the code that deletes site-lisp subdirectories from the default
6921 value of EMACSLOADPATH, as it is no longer needed.
6922 (check_windows_init_file): Now external, not static.
6923 Use Vload_path as is, without adding anything, as this function is now
6924 called when Vload_path is already set up.
6926 * w32.h (check_windows_init_file): Add prototype.
6928 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6930 compatibility with Posix platforms.
6931 (main): Move the call to check_windows_init_file to here from

6935 installation tree, as appropriate.
6937 * callproc.c (init_callproc_1): Call decode_env_path instead of
6938 doing its equivalent by hand.
6939 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
6940 the code that sets Vexec_path run on MS-Windows.

6971 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6972 Remove unnecessary pointer casts.
6973 * alloc.c (record_xmalloc): New function.
6974 * lisp.h (record_xmalloc): New decl.
6975 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6976 more like a function. This is because the pointer cast is not
6977 needed. All uses changed.
6978 * print.c (print_string, print_error_message): Avoid length recalc.
6980 Improve fix for macroexp crash with debugging (Bug#12118).
6981 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6982 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6983 not supposed to be invoked from the garbage collector.

6985 (gc_aset): New function, which is like ASET but can be
6986 used in the garbage collector.

7002 headers (most versions of MinGW w32api don't).
7003 (get_security_info, create_symbolic_link)
7004 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
7006 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
7007 in the argument file name.

7011 have the required privileges.
7012 (get_file_security_desc_by_name): Rename from

7015 with addition of handling of symlinks and support for 'lstat'.
7016 If possible, get file's attributes and security information by
7017 handle, not by name. Produce S_IFLNK bit for symlinks, when
7018 called from 'lstat'.
7019 (stat, lstat): New functions, call 'stat_worker'.
7020 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7021 symlinks when the underlying filesystem supports them.
7023 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7025 Fix macroexp crash on Windows with debugging (Bug#12118).
7026 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7027 checking subscripts; problem introduced with the recent
7028 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7029 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7030 since it's used in non-static inline functions now.
7032 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7033 Don't assume buffer size fits in 'int'. Remove unused local.

7051 * character.c (CHARACTER_INLINE):
7052 * charset.c (CHARSET_INLINE):
7053 * composite.c (COMPOSITE_INLINE):
7054 * dispnew.c (DISPEXTERN_INLINE):
7055 * sysdep.c (SYSTIME_INLINE):
7056 Define to EXTERN_INLINE, so that the corresponding functions
7057 are compiled into code.
7058 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7059 (INLINE_HEADER_END): New macros.
7060 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7082 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7084 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7085 This how ASET and AREF are supposed to work, and makes
7086 it easier to think about future improvements. See
7087 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7088 * charset.h (set_charset_attr): New function.

7342 does that unconditionally. Remove file, which is now empty.
7344 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
7347 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
7349 Export to GDB most of lisp.h's remaining object-like macros.

7468 w32_console_unicode_input.
7469 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
7470 (w32_kbd_patch_key, key_event): Use the codepage returned by
7471 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

7503 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7504 enumeration constants, as PURE and HEAP are too general, and clash
7505 with other headers and sources, such as gmalloc.c and the
7506 MS-Windows system headers. All users changed.
7508 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7510 Revert last save_excursion_save and save_excursion_restore changes.
7511 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7524 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7525 arms of an 'if', not using conditional expressions; otherwise GDB
7526 complains about the types in the unevaluated arm when the argument
7527 is an integer literal.
7528 (xgetint): Simplify expression.
7529 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7530 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7531 Zaretskii in <http://bugs.gnu.org/12036#13>.
7532 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7533 needed now that we have gdb_make_enums_visible.
7534 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7535 (enum enum_USE_LSB_TAG):
7536 New enum types, packaging up enums that need to be exported to GDB.
7538 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

7554 * xdisp.c (syms_of_xdisp): Likewise.
7555 * xfns.c (syms_of_xfns): Likewise.
7557 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7559 Fast save_excursion_save and save_excursion_restore.
7560 * lisp.h (struct Lisp_Excursion): New data type.
7561 (PVEC_EXCURSION): New pseudovector type.
7562 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7563 to deal with it. Adjust comments.

7574 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7576 Fix export of symbols to GDB (Bug#12036).
7577 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
7578 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7579 emacs.c, as this is a more-suitable home. Had this been done earlier
7580 the fix for 12036 would have avoided some of the problems noted in
7581 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7582 would have been more obvious.
7583 * emacs.c: Do not include <verify.h>; no longer needed.
7584 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7585 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7586 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7587 Remove; now done in lisp.h.
7588 * lisp.h (PUBLISH_TO_GDB): New macro.

7591 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7592 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7593 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7594 not be usable in #if. This simplifies things.
7596 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7598 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7600 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7602 Simplify export of symbols to GDB (Bug#12036).
7603 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7604 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7605 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7606 Adjust to changes in lisp.h and emacs.c, by using
7607 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7608 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7609 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7610 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7611 instead of gdb_valbits.
7612 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7613 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7614 instead of gdb_array_mark_flag.
7615 (xboolvector): Get size from $->size, not $->header.size.
7616 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7617 (xreload, hook-run, hookpost-run): Remove.
7618 * emacs.c: Include <verify.h>.
7619 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7620 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7622 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7623 (gdb_USE_LSB_TAG): New enum constants.
7624 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7625 Also define these as enum constants, so they're visible to GDB.
7626 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7627 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7628 as constants, so they're visible to GDB.
7629 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
7630 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
7631 Now enum constants, not macros, so they're visible to GDB.
7632 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7633 more convenient now. All uses changed.
7634 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7635 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7637 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
7639 Explicitly free restriction data that are not needed anymore.
7640 * editfns.c (save_restriction_restore): Free restriction data.
7642 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
7644 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7645 add argument, tune behavior, and adjust all callers.
7647 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7649 Use typedef for EMACS_INT, EMACS_UINT.
7650 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7651 than macros. This simplifies debugging in the usual case, since
7652 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7653 and it allows expressions involving EMACS_INT casts.
7654 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7656 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
7658 * nsterm.m (ns_read_socket): Return early if there is a modal
7661 2012-07-25 Martin Rudalics <rudalics@gmx.at>

7664 that FOCUS-FRAME can be omitted.
7666 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7668 Adjust buffer text indirection counters at the end of Fkill_buffer.
7669 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7670 buffer is definitely dead. This should really fix an issue reported
7671 by Christoph Scholtes again. (Bug#12007).
7672 (init_buffer_once): Initialize indirection counters of

8517 Prefer snprintf to strncpy.
8518 * nsterm.m (ns_term_init):
8519 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8520 * nsterm.m (ns_term_init):
8521 Avoid the need for strncpy, by using build_string or
8522 make_unibyte_string directly. Use dtoastr, not snprintf.
8523 * process.c (Fmake_network_process): Diagnose service names that
8524 are too long, rather than silently truncating them or creating
8525 non-null-terminated names.

8578 srclen argument and return the length of result. Adjust users
8580 (directory_file_name): Fix comment. Change to add srclen argument,
8581 swap 1st and 2nd arguments to obey the common convention.
8582 Adjust users accordingly.
8583 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8585 2012-07-10 Glenn Morris <rgm@gnu.org>
8587 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
8588 Move PENDING_OUTPUT_COUNT definition to configure.
8590 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
8591 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8592 * s/gnu.h (DATA_START): Move definitions to configure.
8594 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8595 We include usg5-4-common.h, which defines them both.
8597 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8598 O_RDONLY already includes it).
8600 Stop ns builds setting the EMACSLOADPATH environment variable.
8601 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8602 Now it does not set EMACSLOADPATH, just returns the load-path string.
8603 * nsterm.h: Update accordingly.
8604 * lread.c [HAVE_NS]: Include nsterm.h.
8605 (init_lread) [HAVE_NS]: Use ns_load_path.

8608 2012-07-09 Glenn Morris <rgm@gnu.org>
8610 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8611 since the included bsd-common.h does so.
8613 Stop ns builds setting the EMACSPATH environment variable.
8614 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8615 (ns_init_paths): Do not set EMACSPATH.
8616 * nsterm.h (ns_exec_path): Add it.
8617 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8620 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8622 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8624 * process.c (wait_reading_process_output): 'waitchannels' was unset
8625 when read_kbd || !NILP (wait_for_cell); fix this.
8627 Add GCC-style 'const' attribute to functions that can use it.
8628 * character.h (char_resolve_modifier_mask):
8629 * keyboard.h (make_ctrl_char):
8630 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8631 (init_character_once, next_almost_prime, init_fns, init_image)
8632 (flush_pending_output, init_sound):

8637 Declare the dummy function with ATTRIBUTE_CONST.
8638 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8639 Add decls with ATTRIBUTE_CONST.
8641 Minor improvements to make_formatted_string.
8642 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8643 where int is good enough, as vsprintf returns an int.
8644 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8646 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8648 Use make_formatted_string to avoid double length calculation.
8649 * lisp.h (make_formatted_string): New prototype.
8650 * alloc.c (make_formatted_string): New function.
8651 * buffer.c (Fgenerate_new_buffer_name): Use it.

8655 * frame.c (make_terminal_frame, set_term_frame_name)
8656 (x_report_frame_params): Likewise.

8673 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8675 Move marker debugging code under MARKER_DEBUG.
8676 * marker.c (MARKER_DEBUG): Move marker debugging code under
8677 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8678 for bootstrap with --enable-checking (~3x slowdown reported
8679 by Juanma Barranquero <lekktu@gmail.com>).
8680 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8682 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8684 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8685 See <http://bugs.gnu.org/11825#29>.
8687 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8689 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8690 has no font, use the frame's font. (Bug#11813)
8691 (display_line): Add commentary about displaying truncation glyphs
8693 (produce_special_glyphs): Move here from term.c.
8695 * term.c (produce_special_glyphs): Move to xdisp.c.
8697 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8700 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8702 * xdisp.c (display_line): Avoid warning about implicit declaration
8705 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8707 * lisp.h: Remove empty conditional.
8709 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8711 * lread.c (load_path_check): Now static.
8713 Fix some minor --with-ns problems found by static checking.
8714 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8715 (x_set_font) [!HAVE_X_WINDOWS]:
8716 * image.c (xpm_load_image) [HAVE_NS]:
8717 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8718 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8719 Remove unused local.
8720 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8721 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8722 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8723 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8724 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8725 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8726 Fix pointer signedness problem.
8727 * xfaces.c (FRAME_X_FONT_TABLE):
8728 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8730 2012-07-07 Glenn Morris <rgm@gnu.org>
8732 * lread.c (load_path_check): New function, split from init_lread.
8733 (init_lread): Reorganize. Motivation:
8734 If EMACSLOADPATH is set, check/warn about that rather than the
8735 defaults, which we are not going to use. Hence we can remove
8736 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8737 Don't warn if site-lisp directories are missing.
8738 If not installed, start from a blank load-path, since
8739 PATH_LOADSEARCH refers to the eventual installation directories.
8741 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8743 Support truncation and continuation glyphs on GUI frames, when
8744 fringes are disabled. (Bug#11832)
8745 * xdisp.c (init_iterator): Get dimensions of truncation and
8746 continuation glyphs even if on GUI frames.
8747 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8748 or both, are absent.
8749 (start_display, move_it_in_display_line_to): Handle the case of a
8750 GUI frame without a fringe to display continuation or truncation
8752 (insert_left_trunc_glyphs): Support GUI frames: make sure
8753 truncation glyphs overwrite enough glyphs from the current line to
8754 have sufficient space in pixels.
8755 (display_line): Support truncation and continuation glyphs on GUI
8756 frames. If some spare pixels are left on the line after inserting
8757 the truncation glyphs, fill that space with a stretch glyph of a
8758 suitably computed width.
8760 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8761 produce_glyphs, to support GUI sessions.
8763 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8765 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8767 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8769 Do not require float-time's arg to fit in time_t (Bug#11825).
8770 This works better on hosts where time_t is unsigned, and where
8771 float-time is applied to the (negative) difference between two times.
8772 * editfns.c (decode_time_components): Last arg is now double *,
8773 not int *, and means to store all the result as a double, without
8774 worrying about whether the seconds part fits in time_t.
8775 All callers changed.
8776 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8777 All callers changed.
8778 (Ffloat_time): Do not fail merely because the specified time falls
8779 outside of time_t range.
8781 2012-07-07 Glenn Morris <rgm@gnu.org>
8783 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8798 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8799 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8800 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

8803 * xfont.c (compare_font_names): Redo to omit the need for casts.
8805 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8807 * xfns.c (Fx_change_window_property): Doc fix.
8808 * w32fns.c (Fx_change_window_property): Doc fix.
8810 * w32fns.c (Fx_window_property): Accept the same arguments as the
8811 X Windows version. Doc fix.
8812 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8814 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8815 Eli Zaretskii <eliz@gnu.org>
8817 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8818 Windows-specific code from nt/config.nt moved here.
8819 Obsolete settings removed.
8821 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8823 * process.c: Avoid unnecessary calls to gettime.
8824 (wait_reading_process_output): Don't get the time of day
8825 when gobbling data immediately and not waiting, as there's no need
8826 for it in that case. This removes a FIXME.
8828 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8830 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8831 is defined (Bug#11768).
8833 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8837 if buffer is not multibyte.
8838 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8839 Call byte_char_debug_check with correct arguments.
8841 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8843 Compile marker debugging code only if ENABLE_CHECKING is defined.
8844 * marker.c (byte_char_debug_check, count_markers):
8845 Use only if ENABLE_CHECKING is defined.
8846 (byte_debug_flag): Remove.
8847 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8848 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8850 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8852 Avoid code repetition in marker-related functions.
8853 * marker.c (attach_marker): New function.
8854 (Fset_marker, set_marker_restricted, set_marker_both)
8855 (set_marker_restricted_both): Use it.
8856 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8857 Consistently rename charno to charpos.

8878 * window.c (save_window_save): Likewise.
8880 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8882 Do not use Fdelete_overlay in delete_all_overlays
8883 to avoid redundant calls to unchain_overlay.
8884 * buffer.c (drop_overlay): New function.
8885 (delete_all_overlays, Fdelete_overlay): Use it.
8886 * minibuf.c (get_minibuffer): Fix comment.
8888 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8890 Port to OpenBSD 5.1 amd64.
8891 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8892 This is needed for OpenBSD, and should be harmless on all BSD systems.
8893 Also, include <sys/sysctl.h>, as it should be available on all
8894 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8895 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8896 use p_pid member, not kp_proc.pid.
8898 2012-07-06 Glenn Morris <rgm@gnu.org>
8900 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8902 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8904 More xmalloc and related cleanup.

8913 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8915 Omit needless casts involving void * pointers and allocation.
8916 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8917 as the former is more robust if P's type is changed.
8918 Prefer xzalloc to xmalloc + memset 0.
8919 Simplify malloc-or-realloc to realloc.
8920 Don't worry about xmalloc returning a null pointer.
8921 Prefer xstrdup to xmalloc + strcpy.
8922 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8924 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8925 alloca of a constant.

8930 hscroll is larger than the line width. Fixes long and futile
8931 looping inside extend_face_to_end_of_line (on a TTY) producing
8932 glyphs that are not needed and thrown away.
8934 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

8962 * xdisp.c (window_hscroll_limited): New function.
8963 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8964 coordinates when window's hscroll is set to insanely large

9036 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9037 This should be fixed in a better way; see Eli Zaretskii in
9038 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9039 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9041 * fileio.c (time_error_value): Rename from special_mtime.
9042 The old name's problems were noted by Eli Zaretskii in
9043 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9045 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9046 This variable's comment says Emacs needs at least one GDB-visible
9047 symbol of type enum pvec_type, to work around GDB problems.
9048 The symbol's value doesn't matter.
9050 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9051 that causes compilation to fail on pre-C99 compilers.
9053 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9055 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9056 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9058 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9060 * buffer.c (init_buffer_once): Fix initialization of
9061 headers for buffer_defaults and buffer_local_symbols.
9062 Reported by Juanma Barranquero <lekktu@gmail.com>.
9064 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9066 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9067 * lisp.h (enum pvec_type): Use fewer bits.
9068 (PSEUDOVECTOR_SIZE_BITS): New constant.
9069 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9070 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9071 change in pvec_type.
9072 (PSEUDOVECTOR_TYPEP): New macro.
9073 (TYPED_PSEUDOVECTORP): Use it.
9074 * fns.c (internal_equal): Adapt code to extract pvectype.
9075 * emacs.c (gdb_pvec_type): Update type.
9076 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9077 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9078 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9079 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9080 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9081 abusing vector->header.next.nbytes.
9082 (live_vector_p): Use PVEC_TYPE.
9083 (mark_object): Adapt code to extract pvectype. Use switch.
9085 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9087 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9088 Tighten new eassert a bit.
9090 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9092 Fix compilation with --enable-gcc-warnings and -O1
9094 * doprnt.c (doprnt): Change type of tem to int, initialize
9095 to avoid compiler warning. Add eassert.
9096 * search.c (simple_search): Initialize match_byte to avoid
9097 compiler warning. Add eassert.
9099 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9101 Avoid weird behavior with large horizontal scrolls.
9102 Without this change, for example, large hscroll values would
9103 mess up Emacs's display on Fedora 15 x86, presumably due to
9104 overflows in int calculations in the display code.
9105 Also, if buffers had long lines, Emacs would freeze.
9106 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9107 (set_window_hscroll): New function, containing the old guts of
9108 Fset_window_hscroll. Return the clipped value.
9109 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9110 This avoids the need to check against PTRDIFF_MAX.
9112 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9114 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9116 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9118 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9120 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9121 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9122 since GCC 4.4.6 issues a bogus warning for them.
9124 Fix bugs in file timestamp newness comparisons.
9125 * fileio.c (Ffile_newer_than_file_p):
9126 * lread.c (Fload): Use full timestamp resolution of files,
9127 not just the 1-second resolution, so that files that are only
9128 slightly newer still count as newer.
9129 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9130 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9132 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9134 * fileio.c: Improve handling of file time marker. (Bug#11852)
9135 (special_mtime): New function.
9136 (Finsert_file_contents, Fverify_visited_file_modtime):
9137 Use it to set special mtime values consistently.
9139 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9141 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9142 marker for non-existing file. (Bug#11852)
9144 2012-07-03 Glenn Morris <rgm@gnu.org>
9146 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9147 and did not make it into globals.h).
9149 2012-07-03 Tom Tromey <tromey@redhat.com>
9151 * window.c (Fset_window_margins, Fset_window_fringes)
9152 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9153 * textprop.c (Fprevious_property_change): No longer static.
9154 * syntax.c (Fsyntax_table_p): No longer static.
9155 * process.c (Fget_process, Fprocess_datagram_address): No longer

9170 * composite.c (Fcomposition_get_gstring): No longer static.
9171 * callproc.c (Fgetenv_internal): No longer static.
9173 * ccl.h: Remove EXFUNs.
9174 * buffer.h: Remove EXFUNs.
9175 * dispextern.h: Remove EXFUNs.
9176 * intervals.h: Remove EXFUNs.
9177 * fontset.h: Remove EXFUN.
9178 * font.h: Remove EXFUNs.
9179 * dosfns.c (system_process_attributes): Remove EXFUN.
9180 * keymap.h: Remove EXFUNs.
9181 * lisp.h: Remove EXFUNs.
9182 * w32term.h: Remove EXFUNs.
9183 * window.h: Remove EXFUNs.
9184 * xsettings.h: Remove EXFUN.
9185 * xterm.h: Remove EXFUN.
9187 2012-07-03 Glenn Morris <rgm@gnu.org>
9189 * lisp.h (Frandom): Make it visible to C.
9190 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9191 buffer for invisible buffers. (Bug#1229)
9193 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9195 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9196 values which aren't power of 2.
9197 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9198 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9201 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9203 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9205 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9207 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9209 * alloc.c (allocate_vector_block): Remove redundant
9210 calls to mallopt if DOUG_LEA_MALLOC is defined.
9211 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9212 avoid calls to mallopt if zero_vector is returned.
9214 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9216 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9217 is enabled, avoid dereferencing NULL current_sblock if
9220 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9222 Cleanup basic buffer management.
9223 * buffer.h (struct buffer): Change layout to use generic vector
9224 marking code. Fix some comments. Change type of 'clip_changed'
9225 to bitfield. Remove unused #ifndef old.
9226 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9227 (GET_OVERLAYS_AT): Fix indentation.
9228 (for_each_per_buffer_object_at): New macro.
9229 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
9230 (Fbuffer_local_variables): Use it.
9231 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9232 * alloc.c (allocate_buffer): Adjust to match new layout of
9233 struct buffer. Fix comment.
9234 (mark_overlay): New function.
9235 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9236 Lisp area of struct buffer.
9237 (mark_object): Use it. Adjust marking of misc objects
9238 and related comments.
9240 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9242 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9243 wrapper that is not needed because the wrapped code is a no-op (zero
9244 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9245 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9247 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9249 * alloc.c (mark_buffer): Simplify. Remove prototype.
9250 (mark_object): Add comment. Reorganize marking of vector-like
9251 objects. Use CHECK_LIVE for all vector-like objects except buffers
9252 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9253 Avoid redundant calls to mark_vectorlike for bool vectors.
9255 2012-06-30 Glenn Morris <rgm@gnu.org>
9257 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9259 * epaths.in (PATH_SITELOADSEARCH): New.
9260 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9261 This is rather than relying on --enable-locallisppath elements
9262 having "site-lisp" in their names. (Bug#10208#25, 11658)
9264 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9266 * w32proc.c (sys_select): Accept and ignore one more argument.
9268 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9270 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9271 (pselect) [!MS_DOS]: Redirect to sys_select.
9273 * sysdep.c: Don't include dos.h and dosfns.h.
9275 * process.c (sys_select):
9276 * msdos.c (sys_select): Accept one more argument and ignore it.
9278 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9279 adapt data types and code to that.
9282 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9283 which clashes with the gnulib function of the same name.
9285 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9287 * font.c (font_style_to_value, font_style_symbolic)
9288 (font_prop_validate_style): Add type checks for values in
9291 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9293 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9296 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9298 * xdisp.c (try_window_id): Undo last change.
9300 * w32.c (getwd): Adjust commentary about startup_dir.
9301 (init_environment): Always call sys_access, even in non-MSVC
9302 builds. Don't chdir to the directory of the Emacs executable.
9303 This undoes code from 1997 which was justified by the need to
9304 "avoid conflicts when removing and renaming directories". But its
9305 downside was that every relative file name was being interpreted
9306 relative to the directory of the Emacs executable, which can never
9307 be TRT. In particular, it broke sys_access when called with
9308 relative file names.
9309 (sys_access): Map GetLastError to errno.
9311 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9313 * window.h (struct window): Change type of 'fringes_outside_margins'

9317 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9320 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9322 * gnutls.c (emacs_gnutls_handshake):
9323 Add QUIT to make the loop interruptible.
9325 2012-06-29 Glenn Morris <rgm@gnu.org>
9327 * charset.c (init_charset): Make lack of etc/charsets fatal.
9329 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9331 * editfns.c (region_limit): Fix type mismatch.
9333 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9335 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9336 undefined. Convert from xassert to eassert.
9337 * nsmenu.m: Convert from xassert to eassert.
9338 * nsterm.m: Likewise.
9340 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9342 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9344 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9346 Avoid integer overflow on scroll-left and scroll-right.
9347 * window.c (HSCROLL_MAX): New macro.
9348 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9349 overflow when requested scroll falls outside ptrdiff_t range.
9351 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9353 * window.h (struct window): Change type of 'hscroll',
9354 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9355 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9356 Adjust users accordingly.
9357 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9358 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9359 from EMACS_INT to ptrdiff_t.
9360 (make_window): Omit redundant initialization.
9362 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9366 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9368 * window.h (struct window): Change type of 'use_time' and
9369 'sequence_number' from Lisp_Object to int.

9379 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9380 adjust comments accordingly.

9435 * alloc.c (allocate_string): Omit intervals initialization.
9436 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9437 as in make_pure_string and make_pure_c_string.
9439 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9441 * alloc.c (allocate_string): Fix last change.
9443 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9493 * alloc.c: Remove build_string.
9494 * lisp.h: Define build_string as static inline. This provides
9495 a better opportunity to optimize away calls to strlen when the
9496 function is called with compile-time constant argument.
9497 * image.c (imagemagick_error): Convert to build_string.
9498 * w32proc.c (sys_spawnve): Likewise.
9499 * xterm.c (x_term_init): Likewise.
9501 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9503 Use sprintf return value instead of invoking strlen on result.
9504 In the old days this wasn't portable, since some sprintf
9505 implementations returned char *. But they died out years ago and
9506 Emacs already assumes sprintf returns int.
9507 Similarly for float_to_string.
9508 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9509 * ccl.c (ccl_driver):
9510 * character.c (string_escape_byte8):

9513 * print.c (print_object):
9514 * xdisp.c (message_dolog):
9515 * xfns.c (syms_of_xfns):
9516 Use sprintf or float_to_string result to avoid need to call strlen.
9517 * data.c (Fnumber_to_string):
9518 Use make_unibyte_string, since the string must be ASCII.
9519 * lisp.h, print.c (float_to_string): Now returns int length.
9520 * term.c (produce_glyphless_glyph):
9521 Use sprintf result rather than recomputing it.
9523 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9524 * Makefile.in (ALL_CFLAGS):
9525 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

9622 * keyboard.c (kbd_buffer_get_event):
9623 * process.c (Faccept_process_output):
9624 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9625 This improves on the previous patch, which introduced a bug
9626 when time_t is unsigned and as wide as intmax_t.
9627 See <http://bugs.gnu.org/9000#51>.
9629 2012-06-23 Eli Zaretskii <eliz@gnu.org>

9658 language ID in the event parameters.
9660 * w32term.c (w32_read_socket): Put the new keyboard codepage into

9690 Don't assume EMACS_TIME and struct timeval are the same type.
9692 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9694 Support higher-resolution time stamps (Bug#9000).
9695 The time stamps are only nanosecond-resolution at the C level,
9696 since that's the best that any real-world system supports now.
9697 But they are picosecond-resolution at the Lisp level, as that's
9698 easy, and leaves room for future OS improvements.
9700 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9703 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9704 Don't get current time unless it's needed.
9706 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9707 now provides it if it's absent.
9708 (start_atimer): Port to higher-res time stamps.
9709 Check for time stamp overflow. Don't get current time more
9710 often than is needed.
9712 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9713 Include systime.h, not time.h.
9714 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9716 * dired.c: Include stat-time.h.
9717 (Ffile-attributes): File times now have higher resolution.

9720 (struct image): Timestamp now has higher resolution.
9722 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9723 has at least microseconds now. All uses removed.
9724 (update_frame, update_single_window, update_window, update_frame_1)
9725 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9726 (duration_to_sec_usec): Remove; no longer needed.
9728 * editfns.c (time_overflow): Now extern.

9733 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9734 (decode_time_components, lisp_seconds_argument): New functions.
9735 (make_time): Now static.
9736 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9737 Report an error if the time is invalid, rather than having the caller
9740 * fileio.c: Include <stat-time.h>
9741 (Fcopy_file): Copy higher-resolution time stamps.
9742 Prefer to set the time stamp via a file descriptor if that works.

9744 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9745 (Fvisited_file_modtime, Fset_visited_file_modtime):
9746 Support higher-resolution time stamps.
9748 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9750 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9752 * image.c (prepare_image_for_display, clear_image_cache)
9753 (lookup_image): Port to higer-resolution time stamps.
9755 * keyboard.c (start_polling, bind_polling_period):
9756 Check for time stamp overflow.
9757 (read_char, kbd_buffer_get_event, timer_start_idle)
9758 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9759 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9760 Port to higher-resolution time stamps. Do not assume time_t is signed.
9761 (decode_timer): New function. Timers are now vectors of length 9,
9762 not 8, to accommodate the picosecond component.
9763 (timer_check_2): Use it.
9765 * nsterm.m (select_timeout, timeval_subtract): Remove.
9766 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9767 as they're a bit more accurate and handle overflow better.
9768 (ns_select): Change prototype to be compatible with pselect.
9769 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9770 * nsterm.h (ns_select): Adjust prototype.
9772 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9773 us-resolution time stamps.
9774 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9776 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9778 * lisp.h (time_overflow): New decl.
9779 (wait_reading_process_output): First arg is now intmax_t, not int,
9780 to accommodate larger waits.
9782 * process.h (struct Lisp_Process.read_output_delay):
9783 Now counts nanoseconds, not microseconds.
9784 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9786 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9787 (wait_reading_process_output):
9788 Port to ns-resolution time stamps.
9789 (Faccept_process_output, wait_reading_process_output):
9790 Check for time stamp overflow. Do not assume time_t is signed.
9791 (select_wrapper): Remove; we now use pselect.
9792 (Fprocess_attributes): Now generates ns-resolution time stamps.
9794 * sysdep.c: Include utimens.h. Don't include utime.h
9795 or worry about struct utimbuf; gnulib does that for us now.
9796 (gettimeofday): Remove; gnulib provides a substitute.
9797 (make_timeval): New function.
9798 (set_file_times): Now sets ns-resolution time stamps.
9799 New arg FD; all uses changed.
9800 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9801 (system_process_attributes):
9802 Now returns ns-resolution time stamp. All uses changed.
9803 Check for time stamp overflow.
9805 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9806 provides a substitute now.
9808 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9809 since it guarantees struct timespec.
9810 (EMACS_TIME): Now struct timespec, so that we can support
9811 ns-resolution time stamps.
9812 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9813 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9814 (EMACS_USECS): Remove.
9815 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9816 so multiply the arg by 1000 before storing it.
9817 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9819 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9820 Port to ns-resolution time stamps.
9821 (EMACS_TIME_NEG_P): Remove; replaced by....
9822 (EMACS_TIME_SIGN): New macro.
9823 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9824 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9825 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9826 (make_timeval, make_lisp_time, decode_time_components): New decls.
9827 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9828 that it mishandled time_t overflow. You can't compare by subtracting!
9829 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9830 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9832 * term.c: Include <sys/time.h>.
9833 (timeval_to_Time): New function, for proper overflow wraparound.

9841 (w32_get_internal_run_time):
9842 Port to higher-resolution Emacs time stamps.
9843 (ltime): Now accepts single 64-bit integer, as that's more convenient
9846 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9848 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9849 for compatibility with pselect. Support ns-resolution time stamps.
9851 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9853 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9854 Check for time stamp overflow, and support ns-resolution time stamps.
9856 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9857 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9858 (timeval_subtract): Remove; no longer needed.
9859 (XTflash, XTring_bell, x_wait_for_event):
9860 Port to ns-resolution time stamps. Don't assume time_t is signed.
9862 2012-06-22 Chong Yidong <cyd@gnu.org>

9866 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9868 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9869 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9870 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9871 staticidx goes up to 1597 out of 1600 = 0x640.)
9873 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9875 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9876 Otherwise, the umask might be mistakenly 0 while handling input signals.

9897 (unwind_format_mode_line): Restore them.
9898 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9900 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9901 since tty frames can be explicitly named.
9902 (prepare_menu_bars): Likewise.
9904 * term.c (Ftty_top_frame): New function.
9906 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

9909 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9910 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9911 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9912 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9913 (METER_1, METER_2): Simplify.
9915 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
9917 * data.c (Fdefalias): Return `symbol' (bug#11686).
9919 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9921 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9922 gets killed during executing of this function (Bug#11665).
9923 Try to always return Qt when the buffer has been actually killed.
9924 (Vkill_buffer_query_functions): In doc-string say that functions
9925 run by this hook should not change the current buffer.
9927 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9929 Fix recently-introduced process.c problems found by static checking.
9930 * process.c (write_queue_push, write_queue_pop, send_process):

9947 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
9949 * lisp.h (eassert): Assume C89 or later.
9950 This removes the need for CHECK.
9951 (CHECK): Remove. Its comments about always evaluating its
9952 argument were confusing, as 'eassert' typically does not evaluate
9955 * coding.c (produce_chars): Use ptrdiff_t, not int.
9957 * xterm.c (x_draw_underwave): Check for integer overflow.
9958 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10144 as the union type is for debugging, not for production.
10145 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10146 Use an inline function on all platforms when using the union type,
10147 since this is simpler and 'static inline' can be used portably

10254 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).

10291 * doprnt.c (doprnt): Truncate multibyte char correctly.
10292 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10293 would mishandle a string argument "Xc" if X was a multibyte
10294 character of length 2: it would truncate after X's first byte
10295 rather than including all of X.
10297 2012-06-06 Chong Yidong <cyd@gnu.org>

10346 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10348 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10349 Convert pctcpu and pctmem to Lisp float properly.
10350 Let the compiler fold better, as 100.0/0x8000 is exact.
10352 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10354 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10361 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10363 For a 'struct window', replace some Lisp_Object fields to
10364 bitfields where appropriate, remove unused fields.

10366 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10367 change its type from Lisp_Object to bitfield.
10368 Change type of 'force_start', 'optional_new_start',
10369 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

10376 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10377 Use 'float' consistently, rather than 'float' in most places
10378 and 'double' in a couple of places.
10380 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10382 * xdisp.c (handle_stop): Detect whether we have overlay strings
10383 loaded by testing it->current.overlay_string_index to be
10384 non-negative, instead of checking whether n_overlay_strings is
10385 positive. (Bug#11587)
10387 2012-05-31 Chong Yidong <cyd@gnu.org>
10389 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10395 * search.c (search_buffer): Remove calls to
10396 r_alloc_inhibit_buffer_relocation, as it is now called by

10402 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10403 for the duration of call to load_charset, to avoid problems with
10404 callers of maybe_unify_char that access buffer text through C
10407 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10408 decrement the inhibition flag, instead of just setting or
10411 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10413 Remove obsolete '#define static' cruft.
10414 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10415 This #undef was "temporary" in 2000; it is no longer needed
10416 now that '#define static' has gone away.
10417 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10418 (gray_bitmap_bits): Remove; no longer needed.

10431 (safe_bcopy): Remove decl; no longer has that name.
10432 (main): Coalesce #if into single bit of code, for simplicity.

10457 * lisp.h (Qdefun): Remove.
10458 * lread.c (read1): Tiny simplification.
10460 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10462 Do not create empty overlays with the evaporate property (Bug#9642).
10463 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10464 Bug#9642, but explicitly check that the buffer the overlay would
10465 be moved to is live and rearrange lines to make sure that errors
10466 will not put the overlay in an inconsistent state.
10467 (Fdelete_overlay): Cosmetics.
10469 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10471 * w32term.c (my_bring_window_to_top): New function.
10472 (x_raise_frame): Use handle returned by DeferWindowPos, which
10473 could be different from the original one.
10474 Call my_bring_window_to_top instead of my_set_foreground_window.
10477 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
10478 by calling BringWindowToTop.

10483 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10485 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10486 This avoids undefined behavior that might cause the eassert
10487 to not catch an out-of-range value.
10489 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10491 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10492 Update dependencies.
10494 2012-05-27 Eli Zaretskii <eliz@gnu.org>

10501 when referring to sectname field in printf format.
10503 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10505 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10506 Only r_alloc_inhibit_buffer_relocation needed to be added;
10507 the others were already declared.
10509 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10510 before checking whether it's out of range. Put the check inside
10512 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10514 2012-05-27 Ken Brown <kbrown@cornell.edu>
10516 * callproc.c (Fcall_process): Restore a line that was accidentally
10517 commented out in the 2011-02-13 change (bug#11547).
10519 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10521 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10522 defined on ralloc.c.
10524 * buffer.c [REL_ALLOC]: Remove prototypes of
10525 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10526 they are now on lisp.h.
10528 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10530 * search.c (search_buffer): Use it to inhibit relocation of buffer
10531 text while re_search_2 is doing its job, because re_search_2 is
10532 passed C pointers to buffer text. (Bug#11519)
10534 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10535 Update value to 24.
10537 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10538 state after an additional call to move_it_in_display_line_to, keep
10539 the values of it->max_ascent and it->max_descent found for the
10541 (pos_visible_p): Revert the comparison against bottom_y to what it
10542 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10545 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10547 Fix coding-related core dumps with gcc -ftrapv.
10548 The code was computing A - B, where A and B are pointers, and B is
10549 random garbage. This can lead to core dumps on platforms that
10550 have special pointer registers, and it also leads to core dumps on
10551 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10552 A - B only when B is initialized properly.
10553 * coding.c (coding_set_source, coding_set_destination): Return void.
10554 (coding_change_source, coding_change_destinations): New functions,
10555 with the old behaviors of coding_set_source and coding_set_destination.
10556 All callers that need an offset changed to use these new functions.
10558 2012-05-26 Glenn Morris <rgm@gnu.org>
10560 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10562 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10564 Extend mouse support on W32 text-mode console.
10565 * xdisp.c (draw_row_with_mouse_face):
10566 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10568 * w32console.c: Include window.h.
10569 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10571 (initialize_w32_display): Initialize mouse-highlight data.
10573 * w32inevt.c: Include termchar.h and window.h.
10574 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10575 moves, call note_mouse_highlight. If help_echo changed, call
10576 gen_help_event to produce help-echo message in the echo area.
10577 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10580 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10582 * lread.c (read1): Simplify slightly to avoid an overflow warning
10583 with GCC 4.7.0 on x86-64.
10585 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10587 * bidi.c (bidi_mirror_char): Revert last change: an int is
10588 definitely wide enough here.
10590 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10592 Fix integer width and related bugs (Bug#9874).

10599 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10600 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10602 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10603 (allocate_pseudovector):
10604 Use int, not EMACS_INT, where int is wide enough.
10605 (inhibit_garbage_collection, Fgarbage_collect):
10606 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10607 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10608 int might not be wide enough.
10609 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10610 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10611 (bidi_at_paragraph_end, bidi_find_paragraph_start)

10624 (Foverlay_recenter, last_overlay_modification_hooks_used)
10625 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10626 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10627 (validate_region): Omit unnecessary test for b <= e,
10628 since that's guaranteed by the previous test.
10629 (adjust_overlays_for_delete): Avoid pos + length overflow.
10630 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10631 (report_overlay_modification):
10632 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10633 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10634 Omit pointer cast, which isn't needed anyway, and doesn't work
10635 after the EMACS_INT -> ptrdiff_t change.
10636 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10637 * buffer.h: Adjust decls to match defn changes elsewhere.
10638 (struct buffer_text, struct buffer):
10639 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10640 Use EMACS_INT, not int, where int might not be wide enough.
10641 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10642 not int, to avoid needless 32-bit limit on 64-bit hosts.
10643 (exec_byte_code): Use tighter memory-full test, one that checks
10644 for alloca overflow. Don't compute the address of the object just
10645 before an array, as that's not portable. Use EMACS_INT, not
10646 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10647 * callint.c (Fcall_interactively):
10648 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10649 * callproc.c (call_process_kill, Fcall_process):
10650 Don't assume pid_t fits into an Emacs fixnum.
10651 (call_process_cleanup, Fcall_process, child_setup):

10655 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10656 (Fcall_process): Simplify handling of volatile integers.

10659 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10660 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10661 (casify_object): Avoid integer overflow when overallocating buffer.
10662 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10663 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10664 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10665 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10666 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10667 integers are now checked earlier. All uses replaced with XINT.
10669 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10670 For CCL_MapSingle, check that content and value are in int range.
10671 (ccl_driver, Fregister_code_conversion_map):
10672 Check that Vcode_version_map_vector is a vector.
10673 (resolve_symbol_ccl_program): Check that vector header is in range.
10674 Always copy the vector, so that we can check its contents reliably
10675 now rather than having to recheck each instruction as it's being
10676 executed. Check that vector words fit in 'int'.
10677 (ccl_get_compiled_code, Fregister_ccl_program)
10678 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10679 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10680 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10681 contents are in range.
10682 (Fccl_execute_on_string): Check that status is in range.
10683 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10684 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10685 Accept and return EMACS_INT, not int, because callers can pass values
10686 out of 'int' range.

10688 (multibyte_chars_in_text, parse_str_as_multibyte)

10691 (string_escape_byte8, Fget_byte):
10692 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10693 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10694 avoid mishandling large integers.
10695 * character.h: Adjust decls to match defn changes elsewhere.
10696 * charset.c (load_charset_map_from_file, find_charsets_in_text)

10701 Don't assume fixnum fits in int.
10702 (load_charset_map_from_vector, Fmap_charset_chars):
10703 Remove now-unnecessary CHECK_NATNUMs.
10704 (Fdefine_charset_internal): Check ranges here, more carefully.
10705 Don't rely on undefined behavior with signed left shift overflow.
10706 Don't assume unsigned int fits into fixnum, or that fixnum fits
10707 into unsigned int. Don't require max_code to be a valid fixnum;
10708 that's not true for gb10830 4-byte on a 32-bit host. Allow
10709 invalid_code to be a cons, for the same reason. Require code_offset
10710 to be a character. Avoid int overflow if max_char is close
10712 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10713 this is intended anyway and avoids some undefined behavior.
10714 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10715 INDEX_TO_CODE_POINT, as that's what it expects.
10716 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10717 * charset.h (DECODE_CHAR): Return int, not unsigned;
10718 this is what was intended anyway, and it avoids undefined behavior.
10719 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10720 integer-overflow issues.
10721 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10722 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10723 where the argument is EMACS_INT, and this behavior is not intended.
10724 * chartab.c (Fmake_char_table, Fset_char_table_range)
10725 (uniprop_get_decoder, uniprop_get_encoder):
10726 Don't assume fixnum fits in int.
10727 * cmds.c (move_point): New function, that does the gist of
10728 Fforward_char and Fbackward_char, but does so while checking
10729 for integer overflow more accurately.
10730 (Fforward_char, Fbackward_char): Use it.
10731 (Fforward_line, Fend_of_line, internal_self_insert)
10732 (internal_self_insert):
10733 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10734 Fix a FIXME, by checking for integer overflow when calculating
10735 target_clm and actual_clm.

10768 (consume_chars): Rewrite to not calculate an address outside buffer.
10769 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10770 Don't access memory outside of the args array.
10771 (Fdefine_coding_system_internal): Check for charset-id overflow.
10772 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10773 result of ENCODE_CHAR.

10792 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
10793 Do not attempt to compute the address of the object just before a
10794 buffer; this is not portable.

11521 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11523 * unexaix.c: Port to more-recent AIX compilers.
11524 (report_error, report_error_1, make_hdr, copy_sym)
11525 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11526 Make arguments const char *, not char *, to avoid violations of C
11527 standard and to fix some AIX warnings reported by Gilles Pion.
11529 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11531 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11532 already have overlays loaded.
11533 (handle_single_display_spec): Before returning without displaying
11534 fringe bitmap, synchronize the bidi iterator with the main display
11535 iterator, by calling iterate_out_of_display_property.
11536 (iterate_out_of_display_property): Detect buffer iteration by
11537 testing that it->string is a Lisp string.
11538 (get_next_display_element): When the current object is exhausted,
11539 and there's something on it->stack, call set_iterator_to_next to
11540 proceed with what's on the stack, instead of returning zero.
11541 (set_iterator_to_next): If called at the end of a Lisp string,
11542 proceed to consider_string_end without incrementing string
11543 position. Don't increment display vector index past the end of
11544 the display vector. (Bug#11417)
11545 (pos_visible_p): Don't report a position visible when move_it_to
11546 stopped at the last line of window, which happens to be scanned
11547 backwards by the bidi iteration. (Bug#11464)
11549 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11551 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11552 and right-margin display specs even if the spec is invalid or we
11553 are on a TTY, and thus unable to display on the fringes.
11554 That's because the text with the property will not be displayed anyway,
11555 so we need to signal to the caller that this is a "replacing"
11556 display spec. This fixes display when the spec is invalid or we
11559 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11561 * unexaix.c (make_hdr): Fix typo in prototype.
11562 This bug broke the build on AIX. Problem reported by Gilles Pion.
11564 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11566 * keyboard.c (kbd_buffer_get_event): Read special events also in
11567 batch mode. (Bug#11415)
11569 2012-05-12 Glenn Morris <rgm@gnu.org>
11571 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11573 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11575 * lisp.mk (lisp): Add newcomment.elc.
11577 2012-05-12 Glenn Morris <rgm@gnu.org>
11579 * Makefile.in (MKDIR_P): New, set by configure.
11580 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11582 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11584 Remove unused function hourglass_started.
11585 * dispextern.h (hourglass_started):
11586 * w32fns.c (hourglass_started):
11587 * xdisp.c (hourglass_started): Remove.
11589 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11591 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11592 Update dependencies.
11594 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11596 * xgselect.c (xg_select): Put maxfds+1 into a var.
11597 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11599 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11601 2012-05-10 Dave Abrahams <dave@boostpro.com>
11603 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11604 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11606 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11608 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11609 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11610 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11611 Initialize xd_registered_buses.
11613 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11615 Untag more efficiently if USE_LSB_TAG.
11616 This is based on a proposal by YAMAMOTO Mitsuharu in
11617 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11618 For an admittedly artificial (nth 8000 longlist) benchmark on
11619 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11620 Emacs's overall text size by 1%.
11621 * lisp.h (XUNTAG): New macro.
11622 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11623 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11624 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11625 * eval.c (Fautoload):
11626 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11627 * frame.h (XFRAME): Use XUNTAG.
11629 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11630 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11631 Remove unportable assumptions about print widths of types like
11633 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11634 intptr_t when converting between pointer and integer, to avoid GCC
11635 warnings about wrong width.
11637 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11639 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11640 stack for each reader_thread, instead of defaulting to 8MB
11641 determined by the linker. This avoids failures in creating
11642 subprocesses on Windows 7, see the discussion in this thread:
11643 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11645 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11647 Fix up display of the *Minibuf-0* buffer in the mini window.
11648 * keyboard.c (read_char): Don't clear the echo area if there's no
11650 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11651 contents of *Minibuf-0*) if there's no message displayed in its stead.
11653 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11655 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11658 2012-05-06 Chong Yidong <cyd@gnu.org>
11660 * lisp.mk (lisp): Update.
11662 2012-05-05 Jim Meyering <meyering@redhat.com>
11664 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11666 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11668 * data.c (PUT_ERROR): New macro.
11669 (syms_of_data): Use it. Add new error type `user-error'.
11670 * undo.c (user_error): New function.
11671 (Fprimitive_undo): Use it.
11672 * print.c (print_error_message): Adjust print style for `user-error'.
11673 * keyboard.c (user_error): New function.
11674 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11676 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11678 Do not limit current-time-string to years 1000..9999.
11679 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11680 (Fcurrent_time_string): Support any year that is supported by the
11681 underlying localtime representation. Don't use asctime, as it
11682 has undefined behavior for years outside the range -999..9999.
11684 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11686 Fix race conditions involving setenv, gmtime, localtime, asctime.
11687 Without this fix, interrupts could mess up code that uses these
11688 nonreentrant functions, since setting TZ invalidates existing
11689 tm_zone or tzname values, and since most of these functions return
11690 pointers to static storage.
11691 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11692 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11693 Grow the critical sections to include not just invoking
11694 localtime/gmtime, but also accessing these functions' results
11695 including their tm_zone values if any, and any related TZ setting.
11696 (format_time_string): Last arg is now struct tm *, not struct tm **,
11697 so that the struct tm is saved in the critical section.
11698 All callers changed. Simplify allocation of initial buffer, partly
11699 motivated by the fact that memory allocation needs to be outside
11700 the critical section.
11702 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11704 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11705 with RESET_INTERVAL.
11707 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11708 Remove duplicated buffer name initialization.
11710 2012-05-02 Jim Meyering <jim@meyering.net>
11712 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11714 * xfns.c (x_window): Use xstrdup (Bug#11375).
11716 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11718 * xdisp.c (pos_visible_p): If already at a newline from the
11719 display string before the 'while' loop, don't walk back the glyphs
11720 from it3.glyph_row. Solves assertion violation when the display
11721 string begins with a newline (egg.el). (Bug#11367)
11723 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11725 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11728 2012-05-01 Glenn Morris <rgm@gnu.org>
11730 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11731 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11732 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11733 All were removed before 23.1.
11735 * dispnew.c: Remove HAVE_LIBNCURSES test;
11736 it is always true on relevant platforms.
11738 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11739 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11741 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11743 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11745 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11746 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11749 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11751 Do not avoid creating empty evaporating overlays (Bug#9642).
11752 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11753 That is, do not delete an evaporating overlay if it becomes
11754 empty after its bounds are adjusted to fit within its buffer.
11755 This fix caused other problems, and I'm reverting it until we get
11756 to the bottom of them.
11758 2012-04-27 Chong Yidong <cyd@gnu.org>
11760 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11762 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11764 * xdisp.c (pos_visible_p): If the window start position is beyond
11765 ZV, start the display from buffer beginning. Prevents assertion
11766 violation in init_iterator when the minibuffer window is scrolled
11767 via the scroll bar.
11769 * window.c (window_scroll_pixel_based): Likewise.
11771 2012-04-27 Chong Yidong <cyd@gnu.org>
11773 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11775 2012-04-27 Glenn Morris <rgm@gnu.org>
11777 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11778 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11780 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11782 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11783 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11785 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11787 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11788 display element, check also the underlying string or buffer
11789 character. (Bug#11341)
11791 * w32menu.c: Include w32heap.h.
11792 (add_menu_item): If the call to AppendMenuW (via
11793 unicode_append_menu) fails, disable Unicode menus only if we are
11794 running on Windows 9X/Me.
11796 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11798 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11799 (xgetint): Add missing shift for LSB tags.
11801 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11803 * keyboard.c (read_char): Don't wipe echo area for select window
11804 events: These might get delayed via `mouse-autoselect-window'
11807 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11809 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11810 manipulation of :loaded-from data.
11812 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11814 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11815 now a cons (bug#11311).
11817 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11819 Do not create empty overlays with the evaporate property (Bug#9642).
11820 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11821 if it becomes empty after its bounds are adjusted to fit within
11822 its buffer. Without this fix, in a nonempty buffer (let ((o
11823 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11824 yields an empty overlay that has the evaporate property, which is
11825 not supposed to happen.
11827 Fix minor GTK3 problems found by static checking.
11828 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11829 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11830 (struct _EmacsFixedClass, emacs_fixed_get_type):
11831 Move decls here from emacsgtkfixed.h, since they needn't be public.
11832 (emacs_fixed_get_type): Now static.
11833 (emacs_fixed_class_init): Omit unused local.
11834 (emacs_fixed_child_type): Remove; unused.
11835 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11836 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11837 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11838 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11839 (EMACS_FIXED_GET_CLASS): Remove; unused.
11840 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11842 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11843 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11845 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11847 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11848 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11849 (__malloc_size_t, __malloc_ptrdiff_t):
11850 Remove. All uses removed, replaced by the definiens if needed,
11851 since we can assume C89 or better now.
11852 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11859 (special_realloc, _realloc_internal_nolock, _realloc_internal)
11860 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11861 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11862 Define using prototypes, not old style.
11863 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11864 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11865 (align): Don't assume that signed integer overflow wraps around.
11866 Omit unused local var.
11867 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11868 (_free_internal_nolock, memalign, mallochook, reallochook):
11869 Omit no-longer-needed casts.
11870 (valloc): Use getpagesize, not __getpagesize.
11871 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11872 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11874 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11876 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11878 Move functions from C to Lisp. Make non-blocking method calls
11879 the default. Implement further D-Bus standard interfaces.
11881 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

11897 (xd_signature, xd_append_arg): Allow float for integer types.
11898 (xd_get_connection_references): New function.
11899 (xd_get_connection_address): Rename from xd_initialize.
11900 Return cached address.
11901 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
11902 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp
11904 (Fdbus_init_bus): New optional arg PRIVATE. Cache address.

11906 (Fdbus_get_unique_name): Make stronger parameter check.
11907 (Fdbus_message_internal): New defun.
11908 (Fdbus_call_method, Fdbus_call_method_asynchronously)
11909 (Fdbus_method_return_internal, Fdbus_method_error_internal)
11910 (Fdbus_send_signal, Fdbus_register_service)
11911 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

11921 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11923 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
11924 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
11925 Do not assume ptrdiff_t is the same width as 'int'.
11927 * alloc.c: Handle unusual debugging option combinations.
11928 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
11929 since the two debugging options are incompatible.
11930 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
11932 (mem_init, mem_insert, mem_insert_fixup):
11933 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
11934 (NEED_MEM_INSERT): Remove; no longer needed.
11936 2012-04-22 Leo Liu <sdl.web@gmail.com>

11940 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11942 * sysdep.c [__FreeBSD__]: Minor cleanups.
11943 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11944 Use Emacs indenting style more consistently. Avoid some casts.
11945 Use 'double' consistently rather than mixing 'float' and 'double'.
11947 2012-04-21 Eduard Wiebe <usenet@pusto.de>
11949 * sysdep.c (list_system_processes, system_process_attributes):
11950 Add implementation for FreeBSD (Bug#5243).

11956 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11958 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11959 It is never used otherwise.
11961 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11963 * print.c (print_preprocess): Only check print_depth if print-circle
11965 (print_object): Check for cycles even when print-circle is nil and
11966 print-gensym is t, but only check print_depth if print-circle is nil.
11968 2012-04-20 Chong Yidong <cyd@gnu.org>
11970 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11971 set the status to "failed" and ensure that sentinel is run.
11973 2012-04-20 Glenn Morris <rgm@gnu.org>
11975 * process.c (Fset_process_inherit_coding_system_flag)
11976 (Fset_process_query_on_exit_flag): Doc fix (mention return value).
11977 (Fmake_network_process, Fmake_serial_process): Doc fix.

11984 row, return zero immediately.
11985 (try_cursor_movement): If inside continuation line, don't back up
11986 farther than the first row after the header line, if any.
11987 Don't consider the header-line row as "partially visible", even if
11988 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
11990 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11992 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"

11999 * Makefile.in (C_WARNINGS_SWITCH): Remove.
12000 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
12001 (ALL_CFLAGS): Use new macros rather than old.
12002 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.

12004 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
12005 -Wunused-result, -Wunused-variable. This should go away once
12006 the Emacs and Gnulib regex code is merged.
12007 (xmalloc, xrealloc): Now static.
12009 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

12026 New extern decls, to avoid calling undeclared functions.
12027 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12028 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12029 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12030 (NEED_MEM_INSERT): New macro.
12031 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12032 Remove one incorrect comment and fix another.

12046 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
12047 Remove decls. This fixes an "It stinks!".
12049 * alloc.c (which_symbols): Fix alignment issue / type clash.
12051 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
12053 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
12054 (struct Lisp_Misc_Any): Likewise.
12055 (struct Lisp_Free): Likewise.
12056 * alloc.c (union aligned_Lisp_Symbol): Define.

12066 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
12067 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
12068 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12069 * s/netbsd.h, s/sol2-6.h:
12070 Remove definition of GC_MARK_STACK, since the default now works.
12071 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12072 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12073 no longer the default.
12074 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12076 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12078 * lread.c (lisp_file_lexically_bound_p):
12079 Fix hang at ";-*-\n" (bug#11238).
12081 2012-04-14 Eli Zaretskii <eliz@gnu.org>
12083 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
12084 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

12095 2012-04-13 Reuben Thomas <rrt@sc3d.org>
12097 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
12099 2012-04-11 Daniel Colascione <dancol@dancol.org>
12101 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12102 against is gone. It's better to use vfork now so that when Cygwin
12103 gains a new, working vfork, we use it automatically (bug#10398).
12105 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
12107 * window.c (save_window_save): Obey window-point-insertion-type.

12123 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
12125 * w32.c (w32_delayed_load): Record the full path of the library
12126 being loaded (bug#10424).
12128 2012-04-09 Glenn Morris <rgm@gnu.org>
12130 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12131 not just in the obarray, before snarfing them. (Bug#11036)

12134 Pass EMACS rather than BUILT_EMACS.
12136 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12138 * process.c (make_process):
12139 * process.h: Add integer `gnutls_handshakes_tried' member to

12146 (emacs_gnutls_read): Use new log functions,
12147 `gnutls_handshakes_tried' process member, and
12148 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12149 attempts per process (connection).
12151 2012-04-09 Chong Yidong <cyd@gnu.org>
12153 * eval.c (Fuser_variable_p, user_variable_p_eh)
12154 (lisp_indirect_variable): Functions deleted.
12155 (Fdefvar): Caller changed.
12157 * callint.c (Finteractive, Fcall_interactively):
12158 * minibuf.c (Fread_variable): Callers changed.
12160 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12162 * xdisp.c (set_cursor_from_row): If the display string appears in
12163 the buffer at position that is closer to point than the position
12164 after the display string, display the cursor on the first glyph of
12165 the display string. Fixes cursor display when a 'display' text
12166 property immediately follows invisible text. (Bug#11094)
12168 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12170 composite.c: use 'double' consistently
12171 * composite.c (get_composition_id): Use 'double' consistently
12172 instead of converting 'float' to 'double' and vice versa; this is
12173 easier to understand and avoids a GCC warning.
12175 2012-04-09 Glenn Morris <rgm@gnu.org>
12177 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12178 preparation for dumping it with emacs. (Bug#4789)
12179 (leimdir): New variable.

12199 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12200 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12201 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12202 objects, as mark_maybe_pointer will catch them otherwise.
12203 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12204 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12215 * makefile.w32-in (OBJ2): Add xml.$(O).
12216 (GLOBAL_SOURCES): Add xml.c.
12217 ($(BLD)/xml.$(O)): New dependency list.
12219 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12220 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12221 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12222 [!WINDOWSNT]: New macros.
12223 (init_libxml2_functions, libxml2_loaded_p): New functions.
12224 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12225 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12226 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12227 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12229 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12230 Call init_libxml2_functions before calling libxml2 functions.
12231 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12233 * emacs.c: Don't include libxml/parser.h.
12234 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12235 xmlCleanupParser directly.
12237 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12239 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12241 * indent.c (Fvertical_motion): If there is a display string at
12242 point, use it.vpos to compute how many lines to backtrack after
12243 move_it_to point. (Bug#11133)
12245 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12247 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12248 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12249 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12250 macros related to unification of CJK characters. For the details,
12251 see the discussion following the message here:
12252 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12254 2012-04-04 Chong Yidong <cyd@gnu.org>
12256 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12258 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12260 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12261 instead of alloca. (Bug#11138)
12263 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12265 * w32menu.c (is_simple_dialog): Properly check lisp types.
12268 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12270 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12271 position we get to after a call to move_it_to fails the
12272 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12273 only if we wind up in a string from display property. (Bug#11063)
12275 * window.c (Fdelete_other_windows_internal): Invalidate the row
12276 and column information about mouse highlight, so that redisplay
12277 restores it after reallocating the glyph matrices. (Bug#7464)
12279 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12280 string comes from a `display' text property, use the buffer
12281 position of that property as if we actually saw that position in
12283 (move_it_by_lines): Remove the assertion that
12284 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12285 violated when there's a before-string at the beginning of a line.
12288 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12290 * xdisp.c (append_space_for_newline): If the default face was
12291 remapped, use the remapped face for the appended newline.
12292 (extend_face_to_end_of_line): Use the remapped default face for
12293 extending the face to the end of the line.
12294 (display_line): Call extend_face_to_end_of_line when the default
12295 face was remapped. (Bug#11068)
12297 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12299 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

12317 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12318 (command_loop_1): Use it; inhibit selection update for
12319 handle-select-window too (Bug#8996).

12323 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12325 2012-03-25 Kenichi Handa <handa@m17n.org>
12327 * dispextern.h (struct glyph): Change the bit length of
12328 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12330 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12332 * s/ms-w32.h (tzname): Include time.h before redirecting to

12337 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12340 * xterm.c (XTread_socket): Only modify handling_signal if
12341 !SYNC_INPUT. (Bug#11080)
12343 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12345 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12346 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12347 when fetching a multibyte character consumes more bytes than
12348 CHAR_BYTES returns, due to unification of CJK characters in
12349 string_char. (Bug#11073)
12351 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12353 * process.c (wait_reading_process_output): Handle pty disconnect
12354 by refraining from sending oneself a SIGCHLD (bug#10933).
12356 2012-03-22 Chong Yidong <cyd@gnu.org>
12358 * dispextern.h (struct it): New member string_from_prefix_prop_p.
12360 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12361 Mark string as coming from a prefix property.
12362 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12363 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12365 2012-03-21 Chong Yidong <cyd@gnu.org>
12367 * xfaces.c (Vface_remapping_alist): Doc fix.
12369 2012-03-20 Eli Zaretskii <eliz@gnu.org>

12383 it fit in a valid range (Bug#11003).
12385 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12387 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12388 that is not from display property, accept the row as a "cursor
12389 row" if one of the string's character has a non-nil `cursor'
12390 property. Fixes cursor positioning when there are newlines in
12391 overlay strings, e.g. in icomplete.el. (Bug#11035)
12393 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12395 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12397 2012-03-12 Chong Yidong <cyd@gnu.org>
12399 * eval.c (inhibit_lisp_code): Rename from
12400 inhibit_window_configuration_change_hook; move from window.c.
12402 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12403 * window.c (run_window_configuration_change_hook)
12404 (syms_of_window): Callers changed.
12406 2012-03-11 Chong Yidong <cyd@gnu.org>
12408 * keymap.c (Fkey_description): Doc fix (Bug#9700).

12427 2012-03-03 Glenn Morris <rgm@gnu.org>
12429 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12431 2012-03-02 Eli Zaretskii <eliz@gnu.org>

12444 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12446 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12447 push_it before setting up the iterator for the first overlay
12448 string, even if we have an empty string loaded.
12449 (next_overlay_string): If there's an empty string on the iterator
12450 stack, pop the stack. (Bug#10903)
12452 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12454 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12455 Suggested by Stefan Monnier in
12456 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12457 * alloc.c (widen_to_Lisp_Object): New static function.
12458 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12459 and widening them to Lisp_Objects. This would work even if
12460 USE_LSB_TAG is defined and wide integers are used, which might
12461 happen in a future version of Emacs.
12463 2012-02-25 Chong Yidong <cyd@gnu.org>
12465 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12470 before saving to clipboard manager.
12472 2012-02-24 Chong Yidong <cyd@gnu.org>
12474 * keyboard.c (process_special_events): Handle all X selection
12475 requests in kbd_buffer, not just the next one (Bug#8869).
12477 2012-02-23 Chong Yidong <cyd@gnu.org>
12479 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12480 call when setting menu-bar-lines and tool-bar-lines parameters.
12481 (unwind_create_frame_1): New helper function.
12483 * window.c (inhibit_window_configuration_change_hook): New var.

12502 when computing $valmask.
12504 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12505 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12506 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12507 It's useless in that case, and it can cause problems on hosts
12508 that allocate halves of EMACS_INT values separately.
12509 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12510 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12511 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12512 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12513 it avoids undefined behavior on hosts where shifting right by more
12514 than the word width has undefined behavior.
12516 2012-02-19 Chong Yidong <cyd@gnu.org>
12518 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12519 (Funhandled_file_name_directory, Ffile_name_as_directory)

12521 (Fsubstitute_in_file_name): Protect against invalid file handler
12522 return values (Bug#10845).

12538 2012-02-15 Chong Yidong <cyd@gnu.org>
12540 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

12556 2012-02-12 Chong Yidong <cyd@gnu.org>
12558 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12559 as that creates a dangerous corner case.
12561 * window.c (Fdelete_window_internal): Invalidate the mouse
12562 highlight (Bug#9904).
12564 2012-02-12 Glenn Morris <rgm@gnu.org>

12594 2012-02-07 Chong Yidong <cyd@gnu.org>
12596 * buffer.c (Fbuffer_local_variables)
12597 (buffer_lisp_local_variables): Handle unbound vars correctly;
12598 don't let Qunbound leak into Lisp.
12600 2012-02-07 Glenn Morris <rgm@gnu.org>
12602 * image.c (Fimagemagick_types): Doc fix.
12604 * image.c (imagemagick-render-type): Change it from a lisp object
12605 to an integer. Move the doc here from the lisp manual.

12635 before BEGV. (Bug#10696)
12637 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12639 Handle overflow when computing char display width (Bug#9496).
12640 * character.c (char_width): Return EMACS_INT, not int.
12641 (char_width, c_string_width): Check for overflow when
12642 computing the width; this is possible now that individual
12643 characters can have unbounded width. Problem introduced
12644 by merge from Emacs 23 on 2012-01-19.

12668 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12670 (x_produce_glyphs): If the component of a composition is a null

12675 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12676 first 2 arguments are identical. This makes inserting large
12677 output from a subprocess an order of magnitude faster on
12678 MS-Windows, where all sbrk'ed memory is always contiguous.

13131 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13132 verifies glyph row's hash code--we have just reallocated the

13297 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13298 is set, removing the need for VIRT_ADDRESS_VARIES.
13299 (PURE_P): Use a more-efficient implementation that needs just one

13302 to 4 (xorl, subq, cmpq, setbe).
13303 * alloc.c (pure): Always extern now, since that's the

13314 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13315 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13316 behave as if the cursor position were at the window margin.
13318 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13319 and the cursor position is out of bounds, behave as if the cursor
13320 position were at the window margin. (Bug#10075)
13322 2011-11-18 Chong Yidong <cyd@gnu.org>
13324 * window.c (Fwindow_combination_limit): Make first argument

13345 * xdisp.c (row_hash): New function, body extracted from
13346 compute_line_metrics.
13347 (compute_line_metrics): Call row_hash, instead of computing the
13350 * dispnew.c (verify_row_hash): Call row_hash for computing the
13351 hash code of a row, instead of duplicating code from xdisp.c.
13353 * dispextern.h (row_hash): Add prototype.
13355 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13357 * frame.c (delete_frame): Don't delete the terminal when the last

13461 The trivial performance wins aren't worth the portability hassles; see
13462 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13464 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

13540 Otherwise, these inline functions do not conform to C99 and
13541 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13542 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13543 * intervals.c (adjust_intervals_for_insertion)

13546 (static_offset_intervals): Remove.
13547 (offset_intervals): Rewrite using the old contents of
13548 static_offset_intervals. The old version didn't conform to C99
13549 because an extern inline function contained a reference to an
13550 identifier with static linkage.

13820 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13822 * image.c (x_create_x_image_and_pixmap):
13823 * w32.c (sys_rename, w32_delayed_load):
13824 * w32font.c (fill_in_logfont):
13825 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13827 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13829 * w32fns.c (w32_default_color_map): New function,
13830 extracted from Fw32_default_color_map.
13831 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13833 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13835 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13837 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13839 * keyboard.c (test_undefined): New function (bug#9751).
13840 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13842 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13844 * sysdep.c (init_sys_modes): Fix the check for the controlling
13845 terminal (Bug#6649).
13847 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13849 * dispextern.h (struct bidi_it): New member next_en_type.
13851 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13852 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13853 current character, check also for next_en_type being WEAK_EN.
13854 (bidi_resolve_weak): Don't enter the expensive loop if the current
13855 position is before next_en_pos. Record the bidi type of the first
13856 non-ET, non-BN character we find, in addition to its position.
13857 (bidi_level_of_next_char): Invalidate next_en_type when
13858 next_en_pos is over-stepped.
13860 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13862 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13863 * editfns.c: Rewrite current-time-zone so that it invokes
13864 the equivalent of (format-time-string "%Z") to get the time zone name.
13865 This fixes a bug when the time zone name contains characters that
13866 need converting from the system time locale to Emacs internal format.
13867 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13868 that patch fixed format-time-string to do the conversion, but
13869 I forgot to fix current-time-zone.
13870 (format_time_string): New function, containing most of
13871 what Fformat_time_string used to contain.
13872 (Fformat_time_string): Rewrite in terms of format_time_string.
13873 This doesn't change this function's behavior.
13874 (current-time-zone): Rewrite to use format_time_string.
13875 This fixes the bug reported by Michael Schierl in
13876 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13877 Jason Rumney's 2007-06-07 change worked around this bug, but
13879 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13881 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13883 * xdisp.c (start_display): If the character at POS is displayed
13884 via a display vector, reset IT->current.dpvec_index to zero.
13885 (try_window_reusing_current_matrix): If a line ends in a display
13886 vector or the next line starts in a display vector, continue
13887 redrawing the window even though the character position of
13888 start_row was reached.
13891 2011-10-18 Chong Yidong <cyd@gnu.org>
13893 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13894 with nobreak-char-display too.
13896 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13898 Fix part 3 of bug#9771.
13899 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13900 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13901 non-neutral characters if the current character is a paragraph
13902 separator (a.k.a. Newline). This avoids running the same
13903 expensive loop twice, once when we consume the preceding newline
13904 and the other time when the line actually needs to be displayed.
13905 Avoid the loop when we see neutrals on the base embedding level
13906 following a character whose directionality is the same as the
13907 paragraph's. This avoids running the expensive loop when a line
13908 ends in a long sequence of neutrals, like control characters.
13909 Add assertion against STRONG_AL type. Slightly rearrange code
13910 that determines the type of a neutral given the first non-neutral
13912 (bidi_level_of_next_char): Set next_en_pos to zero when
13913 invalidating its info.
13915 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13917 * xdisp.c (push_display_prop): Determine whether to record string
13918 or buffer position by IT->string, not by IT->method. Allow
13919 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13920 (move_it_vertically_backward): Don't look for character position
13921 immediately after the newline when in a continuation line.
13924 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13926 * window.c (coordinates_in_window): Rewrite and delabelize
13927 vertical border check. (Bug#5357) (Bug#9618)
13929 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13931 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13932 errors in XSetWindowBorder (bug#9310).
13934 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13936 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13937 avoid crash when xmalloc overrun checking is enabled.
13939 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13941 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13942 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13943 cursor motion with <left> and <right> arrow keys.
13945 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13946 some callers set that themselves.
13948 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13950 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13951 display string and the previous row comes from the same string and
13952 is empty. (Bug#9739) (Bug#9738)
13954 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13956 * doc.c (get_doc_string): Encode file name (bug#9735).
13958 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13960 * bidi.c (bidi_level_of_next_char):
13961 * xdisp.c (get_visually_first_element): Remove old incorrect
13962 comments regarding the Unicode Line Separator character.
13964 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13966 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13968 * alloc.c (Fgc_status): Do not access beyond zombies array
13969 boundary if nzombies > MAX_ZOMBIES.
13970 * alloc.c (dump_zombies): Add missing format specifier.
13972 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13974 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13975 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13977 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13978 Some packages use them to denote characters with modifiers.
13980 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13982 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13983 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13984 matching a pp-number. Rename parameter var to var1.
13986 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13988 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13990 2011-10-08 Glenn Morris <rgm@gnu.org>
13992 * callint.c (Fcall_interactively): Give a more explicit error for the
13993 'c' case with a non-character input. (Bug#8479)
13995 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13997 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13999 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14000 lines that are hscrolled on the left.
14002 * dispnew.c (buffer_posn_from_coords): Account for a possible
14003 presence of header-line. (Bug#4426)
14005 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14007 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14008 Don't advertise functionality which we discourage or doesn't work.
14010 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14012 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14013 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14014 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14015 this makes Emacs dump core during garbage collection on rare
14016 occasions. sizeof is obviously inferior to offsetof here, so
14017 stick with offsetof.
14018 (GC_POINTER_ALIGNMENT): New macro.
14019 (mark_memory): Omit 3rd (offset) arg; caller changed.
14020 Don't assume EMACS_INT alignment is the same as pointer alignment.
14022 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14024 * keyboard.c (read_key_sequence_remapped): New var.
14025 (read_key_sequence): Compute remapping in the right buffer.
14026 (command_loop_1): Use read_key_sequence's remapping directly.
14028 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14030 * dired.c (file_name_completion): Don't expand file name.
14031 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14032 before checking file name handler.
14034 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14035 they've been requested explicitly (bug#9591).
14037 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14039 * keymap.c (Fsingle_key_description): Use make_specified_string
14040 instead of build_string to build string from push_key_description.
14043 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14045 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14046 This fixes a Y2038 bug on 64-bit hosts.
14047 * buffer.c (reset_buffer):
14048 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14049 (Fclear_buffer_auto_save_failure):
14050 Use 0, not -1, to represent an unset failure time, since time_t
14051 might not be signed.
14053 Remove dependency on glibc malloc internals.
14054 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14055 Move back here from lisp.h, but with their new implementations.
14056 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14057 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14058 * charset.c (charset_table_init): New static var.
14059 (syms_of_charset): Use it instead of xmalloc. This removes a
14060 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14061 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14062 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14063 Move back to alloc.c.
14064 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14065 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14067 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14069 * nsterm.m (windowDidResize): Call x_set_window_size only when
14070 ns_in_resize is true. Otherwise set pixelwidth/height and
14071 call change_frame_size (Bug#9628).
14073 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14075 Port --enable-checking=all to Fedora 14 x86-64.
14076 * charset.c (syms_of_charset): Also account for glibc malloc's
14077 internal overhead when calculating the initial malloc maximum.
14079 Port --enable-checking=all to Fedora 14 x86.
14080 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14082 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14083 (overrun_check_realloc, overrun_check_free):
14084 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14085 That way, xmalloc returns a properly-aligned pointer even if
14086 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14087 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14088 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14089 into account when calculating the initial malloc maximum.
14090 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14091 Move here from alloc.c, so that charset.c can use it too.
14092 Properly align; the old code wasn't right for common 32-bit hosts
14093 when configured with --enable-checking=all.
14094 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14095 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14097 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14099 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14102 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14104 * xdisp.c (compute_display_string_end): If there's no display
14105 string at CHARPOS, return -1.
14107 * bidi.c (bidi_fetch_char): When compute_display_string_end
14108 returns a negative value, treat the character as a normal
14109 character not covered by a display string. (Bug#9624)
14111 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14113 * lread.c (Fread_from_string): Fix typo in docstring.
14115 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14117 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14118 newline, reseat the iterator instead of bidi-iterating there one
14119 character at a time. (Bug#9610)
14120 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14121 TO_CHARPOS if the bidi iterator is at base embedding level.
14123 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14125 * lread.c (readevalloop): Use correct code for NBSP.
14126 (read1): Likewise. (Bug#9608)
14128 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14130 * dbusbind.c (Fdbus_register_signal): When service is not
14131 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14133 2011-09-25 Glenn Morris <rgm@gnu.org>
14135 * buffer.c (truncate-lines): Doc fix.
14137 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14139 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14140 (Fset_window_next_buffers): Doc fix.
14142 2011-09-24 Glenn Morris <rgm@gnu.org>
14144 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14146 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14148 Fix minor problems found by static checking.
14149 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14150 * indent.c (Fvertical_motion): Fix == vs = typo.
14152 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14154 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14155 Default value is now t. Doc fix.
14157 * indent.c (Fvertical_motion): Compute and apply the overshoot
14158 logic when moving up, not only when moving down. Fix the
14159 confusing name and values of the it_overshoot_expected variable;
14160 logic changes accordingly. (Bug#9254) (Bug#9549)
14162 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14163 CHARPOS is covered by a display string which includes newlines.
14164 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14165 is covered by a display string with embedded newlines.
14167 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14169 * dbusbind.c (Fdbus_register_signal): Add match rule to
14170 Vdbus_registered_objects_table. (Bug#9581)
14171 (Fdbus_register_method, Vdbus_registered_objects_table):
14174 2011-09-24 Jim Meyering <meyering@redhat.com>
14176 do not ignore write error for any output size
14177 The previous change was incomplete.
14178 While it makes emacs --batch detect the vast majority of stdout
14179 write failures, errors were still ignored whenever the output size is
14180 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14181 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14182 && echo FAIL: ignored write error
14183 FAIL: ignored write error
14184 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14185 && echo FAIL: ignored write error
14186 FAIL: ignored write error
14187 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14189 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14191 * emacs.c (Fkill_emacs): In noninteractive mode exit
14192 non-successfully if a write error occurred on stdout. (Bug#9574)
14194 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14196 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14199 * dispextern.h (struct it): Update the comment documenting what
14202 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14204 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14205 a display string, extend search for cursor position to end of row.
14206 (find_row_edges): If the row ends in a newline from a display
14207 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14208 Handle the case of a display string with multiple newlines.
14209 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14210 non-empty line. Fixes confusing cursor motion with arrow keys at
14211 the beginning of a line that starts with whitespace.
14213 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14215 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14218 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14220 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14221 boolean (Bug#9154).
14223 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14225 * xdisp.c (display_line): Record maximum and minimum buffer
14226 positions even if no glyphs were produced (e.g., by a zero-width
14227 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14228 buffer positions that will be removed from the glyph row because
14230 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14231 column is beyond frame width: don't subtract 1 "pixel" when
14232 computing width of the stretch.
14233 (reseat_at_next_visible_line_start): Undo the change made on
14234 2011-09-17 that saved paragraph information and restored it after
14235 the call to `reseat'. (Bug#9545)
14237 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14239 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14240 and turn window cursor on if cleared (Bug#9415).
14242 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14244 * search.c (boyer_moore): Take unibyte characters from pattern
14245 literally. (Bug#9458)
14247 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14249 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14251 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14253 Fix minor problem found by static checking.
14254 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14255 initialized, to pacify gcc -Wuninitialized.
14257 * fileio.c: Report proper errno when syscall falls.
14258 (Finsert_file_contents): Save and restore errno,
14259 so that report_file_error outputs the correct diagnostic.
14260 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14262 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14264 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14266 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14268 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14269 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14271 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14273 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14274 about the current paragraph and restore it after the call to reseat.
14276 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14277 (bidi_find_paragraph_start): Search back for paragraph beginning
14278 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14279 (bidi_move_to_visually_next): Only trigger paragraph-related
14280 computations when the last character is a newline or at EOB, not
14281 just any NEUTRAL_B. (Bug#9470)
14283 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14284 truncated lines if point is covered by a display string. (Bug#9524)
14286 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14288 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14289 (cons_to_x_long): New function.
14290 (lisp_data_to_selection_data): Use it. Correct the test for
14291 short-versus-long data; it was negated. Break out of vector
14292 loop, for efficiency, when a long datum is discovered.
14294 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14296 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14298 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14300 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14301 GCC PR/17406) by declaring this function with external scope.
14303 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14305 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14306 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14308 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14310 * editfns.c (Fformat): Correctly handle text properties on "%%".
14312 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14314 * xterm.c (x_draw_composite_glyph_string_foreground):
14315 * w32term.c (x_draw_composite_glyph_string_foreground):
14316 * term.c (encode_terminal_code):
14317 * composite.c (composition_update_it, get_composition_id):
14318 * xdisp.c (get_next_display_element)
14319 (fill_composite_glyph_string): Add comments about special meaning
14320 of TAB characters in a composition.
14322 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14324 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14325 This occurs when processing a multibyte format.
14326 Problem reported by Wolfgang Jenker.
14328 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14330 * xdisp.c (try_cursor_movement): Only check for exact match if
14331 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14333 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14335 Remove unused external symbols.
14336 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14337 * xdisp.c (calc_pixel_width_or_height): Now static.
14338 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14339 * indent.c (check_display_width):
14340 * w32term.c: Fix comment to match code.
14341 * xterm.c, xterm.h (x_catching_errors): Remove.
14343 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14345 * xselect.c: Use signed conversions more consistently (Bug#9498).
14346 (selection_data_to_lisp_data): Assume incoming selection data are
14347 signed integers, not unsigned. This is to be consistent with
14348 outgoing selection data, which was modified to use signed integers
14349 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14350 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14351 expects long, not unsigned long.
14353 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14355 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14356 computation of loop end. Reported by Johan Bockgård
14359 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14361 * frame.c (Fother_visible_frames_p): Function deleted.
14363 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14365 * indent.c (compute_motion): Process display vector front to back
14366 rather than the other way around. (Bug#2496)
14368 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14370 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14372 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14374 * minibuf.c (Fread_from_minibuffer): Doc fix.
14376 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14378 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14379 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14381 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14383 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14384 value for non-existent files.
14386 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14388 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14389 set its "size" to -1. This will set the modtime_size field of
14390 the corresponding buffer to -1, which is what
14391 verify-visited-file-modtime expects for files that do not exist.
14394 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14396 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14398 * lisp.h: ... from here. push_key_description is no longer
14399 defined in keyboard.c, so its declaration should not be in
14400 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14401 logically belongs with push_key_description.
14403 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14405 * buffer.h: Include <sys/types.h> instead of <time.h>.
14406 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14407 Problem reported by Herbert J. Skuhra.
14409 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14411 * xml.c (parse_region): Make the parsing work for
14412 non-comment-starting XML files again (bug#9144).
14414 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14416 * image.c (gif_load): Fix calculation of bottom and right corner.
14419 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14421 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14422 redisplay in small windows.
14424 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14426 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14428 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14430 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14431 Operate on live windows only.
14433 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14435 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14437 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14439 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14440 only under bidi iteration.
14442 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14444 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14446 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14448 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14449 Without this fix, the command to link temacs failed due to an
14450 undefined symbol __builtin_isnan. This is because
14451 /usr/include/iso/math_c99.h #defines isnan(x) to
14452 __builtin_isnan(x), but the bundled gcc, which identifies itself
14453 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14455 * floatfns.c (isnan): #undef, and then #define to a clone of
14457 (Fisnan): Always define, since it's always available now.
14458 (syms_of_floatfns): Always define isnan at the Lisp level.
14460 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14462 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14464 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14466 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14467 The previous code assumed that file offsets (off_t values) fit in
14468 EMACS_INT variables, which is not true on typical 32-bit hosts.
14469 The code messed up by falsely reporting buffer overflow in cases
14470 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14471 when "big" contains more than 2**29 bytes, even though this
14472 inserts just one byte and does not overflow the buffer.
14473 (Finsert_file_contents): Store file offsets as off_t
14474 values, not as EMACS_INT values. Check for overflow when
14475 converting between EMACS_INT and off_t. When checking for
14476 buffer overflow or for overlap, take the offsets into account.
14477 Don't use EMACS_INT for small values where int suffices.
14478 When checking for overlap, fix a typo: ZV was used where
14479 ZV_BYTE was intended.
14480 (Fwrite_region): Don't assume off_t fits into 'long'.
14481 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14483 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14485 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14487 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14489 sprintf-related integer and memory overflow issues (Bug#9412).
14491 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14492 (esprintf, exprintf, evxprintf): New functions.
14493 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14494 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14495 (modify_event_symbol): Do not assume that the length of
14496 name_alist_or_stem is safe to alloca and fits in int.
14497 (Fexecute_extended_command): Likewise for function name and binding.
14498 (Frecursion_depth): Wrap around reliably on integer overflow.
14499 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14500 since some callers pass EMACS_INT values.
14501 (Fsingle_key_description): Don't crash if symbol name contains more
14502 than MAX_ALLOCA bytes.
14503 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14504 (get_minibuffer): Arg is now EMACS_INT, not int.
14505 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14506 (esprintf, exprintf, evxprintf): New decls.
14507 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14509 * dbusbind.c (signature_cat): New function.
14510 (xd_signature, Fdbus_register_signal):
14511 Do not overrun buffer; instead, report string overflow.
14513 * dispnew.c (add_window_display_history): Don't overrun buffer.
14514 Truncate instead; this is OK since it's just a log.
14516 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14517 even if the time zone offset is outlandishly large.
14518 Don't mishandle offset == INT_MIN.
14520 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14521 when creating daemon; the previous buffer-overflow check was incorrect.
14523 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14524 which has the guts of the old verror function.
14526 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14527 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14529 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14530 (font_unparse_xlfd): Don't blindly alloca long strings.
14531 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14532 fits in int, when using sprintf. Use single snprintf to count
14533 length of string rather than counting it via multiple sprintfs;
14534 that's simpler and more reliable.
14535 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14536 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14537 sprintf, in case result does not fit in int.
14539 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14540 (fontset_from_font): Print it.
14542 * frame.c (tty_frame_count): Now printmax_t, not int.
14543 (make_terminal_frame, set_term_frame_name): Print it.
14544 (x_report_frame_params): In X, window IDs are unsigned long,
14545 not signed long, so print them as unsigned.
14546 (validate_x_resource_name): Check for implausibly long names,
14547 and don't assume name length fits in 'int'.
14548 (x_get_resource_string): Don't blindly alloca invocation name;
14549 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14552 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14553 (xg_check_special_colors, xg_set_geometry):
14554 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14556 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14557 Use esprintf, not sprintf, in case result does not fit in int.
14559 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14560 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14561 it as a large positive number.
14562 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14563 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14565 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14566 in case result does not fit in int.
14568 * print.c (float_to_string): Detect width overflow more reliably.
14569 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14570 buffer overrun. Don't assume list length fits in 'int'. Treat
14571 print length of 0 as 0, not as infinity; to be consistent with other
14572 uses of print length in this function. Don't overflow print length
14573 index. Don't assume hash table size fits in 'long', or that
14574 vectorlike size fits in 'unsigned long'.
14576 * process.c (make_process): Use printmax_t, not int, to format
14577 process-name gensyms.
14579 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14581 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14582 to avoid potential buffer overrun.
14584 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14585 if X resource line is longer than 512 bytes.
14587 * xfns.c (x_window): Make sprintf buffer a bit bigger
14588 to avoid potential buffer overrun.
14590 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14592 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14594 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14596 Integer overflow fixes for scrolling, etc.
14597 Without these, Emacs silently mishandles large integers sometimes.
14598 For example, "C-u 4294967297 M-x recenter" was treated as if
14599 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14601 * xdisp.c (try_window_id): Check Emacs fixnum range before
14602 converting to 'int'.
14604 * window.c (window_scroll_line_based, Frecenter):
14605 Check that an Emacs fixnum is in range before assigning it to 'int'.
14606 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14607 values converted from Emacs fixnums.
14608 (Frecenter): Don't wrap around a line count if it is out of 'int'
14609 range; instead, treat it as an extreme value.
14610 (Fset_window_configuration, compare_window_configurations):
14611 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14613 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14614 that can exceed INT_MAX. Check that EMACS_INT value is in range
14615 before assigning it to the (possibly-narrower) index.
14616 (match_limit): Don't assume that a fixnum can fit in 'int'.
14618 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14621 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14622 (Fvertical_motion): Don't wrap around LINES values that don't fit
14623 in 'int'. Instead, treat them as extreme values. This is good
14624 enough for windows, which can't have more than INT_MAX lines anyway.
14626 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14628 * Require libxml/parser.h to avoid compilation warning.
14630 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14632 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14633 since this reportedly can destroy thread storage.
14635 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14637 * syntax.c (find_defun_start): Update all cache variables if
14638 exiting early (Bug#9401).
14640 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14642 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14644 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14645 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14646 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14648 * term.c (tty_append_glyph): New function.
14649 (produce_stretch_glyph): Static function and its prototype deleted.
14651 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14654 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14656 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14657 when checking :margin (Bug#9390).
14658 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14659 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14660 so that the name doesn't mislead. All uses changed.
14662 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14664 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14667 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14669 * xdisp.c (move_it_to): Don't bail out early when reaching
14670 position beyond to_charpos, if we are scanning backwards.
14671 (move_it_vertically_backward): When DY == 0, make sure we get to
14672 the first character in the line after the newline.
14674 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14676 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14677 (ccl_driver): Do not generate an out-of-range pointer.
14678 (Fccl_execute_on_string): Remove unnecessary check for
14679 integer overflow, noted by Stefan Monnier in
14680 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14681 Remove a FIXME that didn't need fixing.
14682 Simplify the newly-introduced buffer reallocation code.
14684 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14686 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14688 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14690 Integer and memory overflow issues (Bug#9196).
14692 * doc.c (get_doc_string): Rework so that
14693 get_doc_string_buffer_size is the actual buffer size, rather than
14694 being 1 less than the actual buffer size; this makes xpalloc more
14697 * image.c (x_allocate_bitmap_record, cache_image):
14698 * xselect.c (Fx_register_dnd_atom):
14699 Simplify previous changes by using xpalloc.
14701 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14702 since either will do and ptrdiff_t is convenient with xpalloc.
14704 * charset.c (charset_table_size)
14705 (struct charset_sort_data.priority): Now ptrdiff_t.
14706 (charset_compare): Don't overflow if priorities differ greatly.
14707 (Fsort_charsets): Don't assume list length fits in int.
14708 Check for size-calculation overflow when allocating sort data.
14709 (syms_of_charset): Allocate an initial charset table that is
14710 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14712 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14714 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14715 The actual value is always <= INT_MAX, and leaving it unsigned made
14716 overflow checking harder.
14718 * dispextern.h (struct glyph_matrix.rows_allocated)
14719 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14720 with xpalloc. The values are still always <= INT_MAX.
14722 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14724 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14725 (SAFE_NALLOCA): New macro.

14730 (revalidate_region_cache, know_region_cache, region_cache_forward)
14731 (region_cache_backward, pp_cache):
14732 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14733 so that ptrdiff_t * can be passed to xpalloc.

14750 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14752 Don't update size of array until after memory allocation succeeds,
14753 because xmalloc/xrealloc may not return.
14754 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14755 now that we have proper integer overflow checking.
14756 (record_overlay_string, overlay_strings): Catch overflows when
14757 calculating size of overlay_str_buf.
14759 * callproc.c (Fcall_process): Check for size overflow when

14763 require adding more-complicated checks.
14765 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14766 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

14806 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14808 * emacs.c (main): Do not reallocate argv, since there is a null at
14809 the end that can be overwritten, and this way there's no need to
14810 worry about size-calculation overflow.
14811 (sort_args): Check for size-calculation overflow.
14813 * eval.c (init_eval_once, grow_specpdl): Don't update size until

14820 (x_set_alpha): Do not assume XINT fits in int.
14822 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14823 This is for the members text_lines, text_cols, total_lines, total_cols,

14941 Use them to make the following changes clearer.
14942 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

14945 (SELECTION_QUANTUM): Remove, replacing with ...
14946 (selection_quantum): ... new function, which avoids overflow.
14948 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

14966 Don't store size until memory allocation succeeds.
14967 (x_get_window_property): Plug memory leak on memory exhaustion.
14968 Don't double-block input; malloc is safe here. Don't assume 2**34
14969 - 4 fits in unsigned long. Add an xassert to check
14970 XGetWindowProperty overflow. Be more careful about overflow
14971 calculations, and distinguish size from memory overflow better.

14973 unsigned int is less than INT_MAX.
14974 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

14978 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14979 result parameters unless successful. Rely on cons_to_unsigned
14980 to report problems with elements; the old code wasn't right anyway.

15062 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15063 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15064 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15065 length, not size_t. Use ptrdiff_t for index, not int.
15066 (keyremap_step, read_key_sequence): Redo bufsize check to avoid

15095 Prefer int to unsigned where either will do.
15096 (tiff_handler): New function, combining the cores of the
15097 old tiff_error_handler and tiff_warning_handler.
15098 This function is rewritten to use vsnprintf and thereby avoid
15099 stack buffer overflows. It uses only the features of vsnprintf
15100 that are common to both POSIX and native Microsoft.
15101 (tiff_error_handler, tiff_warning_handler): Use it.
15102 (tiff_load, gif_load, imagemagick_load_image):
15103 Don't assume :index value fits in 'int'.

15146 buffers, return left-to-right.
15147 (set_cursor_from_row): Consider candidate row a win if its glyph
15148 represents a newline and point is on that newline. Fixes cursor
15149 positioning on the newline at EOL of R2L text within L2R
15150 paragraph, and vice versa.
15151 (try_cursor_movement): Check continued rows, in addition to
15152 continuation rows. Fixes unwarranted scroll when point enters a
15153 continued line of R2L text within an L2R paragraph, or vice versa.
15154 (cursor_row_p): Consider the case of point being equal to
15155 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15156 from the end of a short line to the beginning of a continued line
15157 of R2L text within L2R paragraph.
15158 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15159 composed characters.

15174 2011-08-22 Kenichi Handa <handa@m17n.org>
15176 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15177 extra slot even if the purpose is char-code-property-table.
15179 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15181 * xdisp.c (redisplay_window): When computing centering_position,
15182 account for the height of the header line. (Bug#8874)
15184 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15185 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15186 candidate is selected by the mouse, and that candidate has a
15187 composed character under the mouse.
15189 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15190 coordinates reported by pos-visible-in-window-p for a composed
15191 character in column zero.
15193 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15195 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15197 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15199 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15200 consider it a hit if to_charpos is anywhere in the range of the
15201 composed buffer positions.
15203 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15205 * image.c (gif_load): Don't assume that each subimage has the same
15206 dimensions as the base image. Handle disposal method that is
15207 "undefined" by the gif spec (Bug#9335).
15209 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15211 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
15212 (Fcondition_case): Document `debug' symbol in error handler.
15214 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15216 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15217 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15218 from an Org mode buffer to a Speedbar frame.
15220 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15221 a composition, take its buffer position from IT->cmp_it.charpos.
15222 Fixes cursor positioning at the beginning of a line that begins
15223 with a composed character.
15225 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15227 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15228 character bidirectional type, use STRONG_L instead. Fixes crashes
15229 in a buffer produced by `describe-categories'.
15231 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15232 members before the level stack, so they would be saved and
15233 restored when copying iterator state. Fixes incorrect reordering
15234 around TABs covered by display properties.
15236 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15238 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
15240 2011-08-17 Chong Yidong <cyd@stupidchicken.com>

15243 (internal_condition_case_2, internal_condition_case_n):
15244 Remove unnecessary aborts (Bug#9081).
15246 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15248 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15249 has no `load' handler, try opening the file locally. (Bug#9311)
15251 2011-08-16 Ken Brown <kbrown@cornell.edu>
15253 * gmalloc.c: Expand comment.
15255 2011-08-16 Eli Zaretskii <eliz@gnu.org>

15269 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
15271 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
15272 in the static heap.
15273 [CYGWIN] (special_realloc): New function.
15274 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
15275 requests to realloc storage in the static heap.

15304 after the pid of the process is set to -1 (Bug#8162).
15306 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15308 * xdisp.c (move_it_in_display_line_to): Don't invoke
15309 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15310 ppos_it. Fixes vertical cursor motion when line beginning is
15311 covered by an image. (Bug#9296)
15313 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15315 * nsterm.h (ns_run_ascript): Declare.

15319 (ns_run_ascript): New function.
15320 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15321 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15322 the event loop. Get status from as_status (Bug#7276).
15324 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15325 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15326 the event loop (Bug#7276).
15328 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15330 * gnutls.c (QCgnutls_bootprop_priority)
15331 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
15332 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
15333 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
15334 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
15335 (QCgnutls_bootprop_verify_hostname_error)

15352 (Fnetwork_interface_list): Allocate in increments of bytes instead
15353 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15354 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15356 (struct ifflag_def): notrailers is smart on OSX.
15357 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15358 Get hardware address with getifaddrs if available.
15360 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15362 * xdisp.c (iterate_out_of_display_property): xassert that
15363 IT->position is set to within IT->object's boundaries. Break from
15364 the loop as soon as EOB is reached; avoids infloops in redisplay
15365 when IT->position is set up wrongly due to some bug.
15366 Set IT->current to match the bidi iterator unconditionally.
15367 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15368 entry. Force push_it to save on the stack the current
15369 buffer/string position, to be restored by pop_it. Fix flags in
15370 the iterator structure wrt the object coming from a display
15371 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15372 properties. (Bug#9284)
15374 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15376 * fontset.c (fontset_get_font_group): Add proper type checks.

15389 no-display-properties-and-no-overlays under bidi display.
15390 Set disp_pos in the bidi iterator to avoid searches for display
15391 properties and overlays.
15393 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15395 * editfns.c (Fset_time_zone_rule): Document relationship with the

15404 restore_point_unwind (Bug#5984).
15406 2011-08-07 Juri Linkov <juri@jurta.org>
15408 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15409 to show the arg `TIME' instead of `TIMEVAL'.
15411 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15413 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15414 display property strides EOL and includes a newline, as in
15415 longlines-mode. (Bug#9254)
15416 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15417 word-wrap under bidirectional display. (Bug#9224)
15419 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15420 is non-zero, even if the data buffer is NULL. Fixes a crash in
15421 vertical-motion with longlines-mode. (Bug#9254)
15423 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15425 * bidi.c <bidi_cache_total_alloc>: Now static.
15426 (bidi_initialize): Initialize bidi_cache_total_alloc.
15428 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15431 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15432 amount allocated this far in `bidi_cache_total_alloc'.
15433 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15434 non-zero, only free the data buffer without restoring the cache
15435 contents. All callers changed.
15437 * dispextern.h (bidi_unshelve_cache): Update prototype.
15439 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15440 (move_it_in_display_line, move_it_to)
15441 (move_it_vertically_backward, move_it_by_lines): Replace the call
15442 to xfree to an equivalent call to bidi_unshelve_cache.
15443 (move_it_in_display_line_to): Fix logic of returning
15444 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15446 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15448 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15449 came from a string character with a `cursor' property. (Bug#9229)

15463 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15465 * xterm.c (x_find_topmost_parent): New function.
15466 (x_set_frame_alpha): Find topmost parent window with
15467 x_find_topmost_parent and set the property there also (bug#9181).
15468 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15470 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>

15496 for a display string or property. If found, set DISP_PROP_P
15499 * bidi.c (bidi_fetch_char): Accept an additional argument
15500 DISP_PROP_P, and pass it to compute_display_string_pos.
15501 Only handle text covered by a display string if DISP_PROP_P is returned
15502 non-zero. All callers of bidi_fetch_char changed.
15504 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15506 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

15530 * regex.c (re_comp): Protoize.
15531 (re_exec): Fix return type.
15532 (regexec): Fix type of `ret'. (Bug#9203)
15534 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15536 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15537 This is needed if max-image-size is a floating-point number.
15539 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15541 * print.c (print_object): Print empty symbol as ##.

15586 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15588 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15589 Without this fix, if a signal arrives just after memory fills up,
15590 'malloc' might be invoked reentrantly.
15592 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15593 In other words, assume that every image size is allowed, on non-X
15594 hosts. This assumption is probably wrong, but it lets Emacs compile.
15596 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15598 * regex.c (re_iswctype): Convert return values to boolean.

15615 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15616 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15617 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15618 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15619 (bidi_find_other_level_edge):
15620 Use ptrdiff_t instead of EMACS_INT where either will do.
15621 This works better on 32-bit hosts configured --with-wide-int.
15622 (bidi_cache_ensure_space): Check for size-calculation overflow.
15623 Use % rather than repeated addition, for better worst-case speed.
15624 Don't set bidi_cache_size until after xrealloc returns, because it
15626 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15627 (bidi_cache_ensure_space): Also check that the bidi cache size
15628 does not exceed that of the largest Lisp string or buffer. See Eli
15629 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15631 * alloc.c (__malloc_size_t): Remove.
15632 All uses replaced by size_t. See Andreas Schwab's note
15633 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15635 * image.c: Improve checking for integer overflow.
15636 (check_image_size): Assume that f is nonnull, since
15637 it is always nonnull in practice. This is one less thing to
15638 worry about when checking for integer overflow later.
15639 (x_check_image_size): New function, which checks for integer
15640 overflow issues inside X.
15641 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15642 This removes the need for a memory_full check.
15643 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15644 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15645 (xbm_read_bitmap_data): Change locals back to 'int', since
15646 their values must fit in 'int'.
15647 (xpm_load_image, png_load, tiff_load):
15648 Invoke x_create_x_image_and_pixmap earlier,
15649 to avoid much needless work if the image is too large.
15650 (tiff_load): Treat overly large images as if
15651 x_create_x_image_and_pixmap failed, not as malloc failures.
15652 (gs_load): Use x_check_image_size.
15654 * gtkutil.c: Omit integer casts.
15655 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15656 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15658 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15660 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15661 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15662 would wrongly return t on a 64-bit host.
15664 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15665 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15666 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15667 and therefore cause GCC to emit a bogus diagnostic in some cases.
15669 * image.c: Integer signedness and overflow and related fixes.
15670 This is not an exhaustive set of fixes, but it's time to
15671 record what I've got.
15672 (lookup_pixel_color, check_image_size): Remove redundant decls.
15673 (check_image_size): Don't assume that arbitrary EMACS_INT values
15674 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15675 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15676 (tiff_load, imagemagick_load_image):
15677 Check for overflow in size calculations.
15678 (x_create_x_image_and_pixmap): Remove unnecessary test for
15679 xmalloc returning NULL; that can't happen.
15680 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15681 (xpm_color_bucket): Use better integer hashing function.
15682 (xpm_cache_color): Don't possibly over-allocate memory.
15683 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15684 (gif_memory_source):
15685 Use ptrdiff_t, not int or size_t, to record sizes.
15686 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15687 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15688 either works, as we prefer signed integers.
15689 (tiff_read_from_memory, tiff_write_from_memory):
15690 Return tsize_t, not size_t, since that's what the TIFF API wants.
15691 (tiff_read_from_memory): Don't fail simply because the read would
15692 go past EOF; instead, return a short read.
15693 (tiff_load): Omit no-longer-needed casts.
15694 (Fimagemagick_types): Don't assume size fits into 'int'.
15696 Improve hashing quality when configured --with-wide-int.
15697 * fns.c (hash_string): New function, taken from sxhash_string.
15698 Do not discard information about ASCII character case; this
15699 discarding is no longer needed.
15700 (sxhash-string): Use it. Change sig to match it. Caller changed.
15701 * lisp.h: Declare it.
15702 * lread.c (hash_string): Remove, since we now use fns.c's version.
15703 The fns.c version returns a wider integer if --with-wide-int is
15704 specified, so this should help the quality of the hashing a bit.
15706 * emacs.c: Integer overflow minor fix.
15707 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15708 Define only if GNU_LINUX.
15709 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15711 * dispnew.c: Integer signedness and overflow fixes.
15712 Remove unnecessary forward decls, that were a maintenance hassle.
15713 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15715 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15716 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15717 (prepare_desired_row, line_draw_cost):
15718 Use int, not unsigned, where either works.
15719 (save_current_matrix, restore_current_matrix):
15720 Use ptrdiff_t, not size_t, where either works.
15721 (init_display): Check for overflow more accurately, and without
15722 relying on undefined behavior.
15724 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15725 Remove, replacing with the new symbols in lisp.h. All uses changed.
15726 * fileio.c (make_temp_name):
15727 * filelock.c (lock_file_1, lock_file):
15728 * xdisp.c (message_dolog):
15729 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15730 Use pMd etc. instead.
15731 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15732 replacing the pWIDE etc. symbols removed from editfns.c.
15734 * keyboard.h (num_input_events): Now uintmax_t.
15735 This is (very slightly) less likely to mess up due to wraparound.
15738 * buffer.c: Integer signedness fixes.
15739 (alloc_buffer_text, enlarge_buffer_text):
15740 Use ptrdiff_t rather than size_t when either will do, as we prefer
15743 * alloc.c: Integer signedness and overflow fixes.
15744 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15745 (__malloc_size_t): Default to size_t, not to int.
15746 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15747 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15748 Prefer ptrdiff_t to size_t when either would do, as we prefer
15750 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15751 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15752 Now const. Initialize with values that are in range even if char
15754 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15755 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15756 These functions do the right thing with sizes > 2**32.
15757 (check_depth): Now ptrdiff_t, not int.
15758 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15759 Adjust to new way of storing sizes. Check for size overflow bugs
15761 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15762 slightly wrong anyway, as it missed one instance of
15763 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15764 (refill_memory_reserve): Omit needless cast to size_t.
15765 (mark_object_loop_halt): Mark as externally visible.
15767 * xselect.c: Integer signedness and overflow fixes.
15768 (Fx_register_dnd_atom, x_handle_dnd_message):
15769 Use ptrdiff_t, not size_t, since we prefer signed.
15770 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15771 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15772 x_dnd_atoms_size and x_dnd_atoms_length.
15774 * doprnt.c: Prefer signed to unsigned when either works.
15776 * doprnt.c (doprnt):
15778 * xdisp.c (vmessage):
15779 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15780 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15781 prefer signed arithmetic to avoid comparison confusion.
15782 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15783 but is a bit tricky.
15785 Assume freestanding C89 headers, string.h, stdlib.h.
15786 * data.c, doprnt.c, floatfns.c, print.c:
15787 Include float.h unconditionally.
15788 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15789 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15790 * regex.c: Likewise for stddef.h, string.h.
15791 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15792 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15793 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15794 (STDC_HEADERS): Remove obsolete defines.
15795 * sysdep.c: Include limits.h unconditionally.
15797 Assume support for memcmp, memcpy, memmove, memset.
15798 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15799 * regex.c (memcmp, memcpy):
15800 Remove; we assume C89 now.
15802 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15803 (__malloc_safe_bcopy): Remove; no longer needed.
15805 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15806 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15807 well either way, and we prefer signed to unsigned.
15809 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15811 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15812 closes the connection while we're reading (bug#9182).
15814 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15816 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15817 are specified (Bug#9168).
15819 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15821 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15822 Found by GCC static checking and --with-wide-int on a 32-bit host.
15824 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15826 * xdisp.c (compute_display_string_pos): Fix logic of caching
15827 previous display string position. Initialize cached_prev_pos to
15828 -1. Fixes slow-down at the beginning of a buffer.
15830 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15832 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15833 for attrs[LFACE_FONTSET_INDEX].
15835 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15837 * xml.c (parse_region): Remove unused local
15838 that was recently introduced.
15840 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15842 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15843 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15845 * xdisp.c (move_it_in_display_line_to): Record the best matching
15846 position for TO_CHARPOS while scanning the line, and restore it on
15847 exit if none of the characters scanned was an exact match.
15848 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15849 when exact match is impossible due to invisible text, and the
15850 lines are truncated.
15852 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15854 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15857 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15859 Fix a significant slow-down of cursor motion with C-n, C-p,
15860 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15861 auto-repeat under bidi redisplay in fontified buffers.
15862 * xdisp.c (compute_stop_pos_backwards): New function.
15863 (next_element_from_buffer): Call compute_stop_pos_backwards to
15864 find a suitable prev_stop when we find ourselves before
15866 (reseat): Don't look for prev_stop, as that could mean a very long
15868 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15869 <cached_disp_overlay_modiff>: Cache for last found display string
15871 (compute_display_string_pos): Return the cached position if asked
15872 about the same buffer in the same area of character positions, and
15873 the buffer wasn't changed since the time the display string
15874 position was cached.
15876 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15878 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15879 is an integer, which is important for empty lines. (Bug#9149)
15881 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15883 * frame.c (Fmodify_frame_parameters): In tty case, update the
15884 default face if necessary (Bug#4238).
15886 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15888 * editfns.c (Fstring_to_char): No need to explain what a character
15889 is in the docstring (Bug#6576).
15891 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15893 * xml.c (parse_region): Make sure we always return a tree.
15895 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15897 * xml.c (parse_region): If a document contains only comments,
15900 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15902 * xml.c (make_dom): Return comments, too.
15904 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15907 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15908 and the surrounding thread.
15909 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15910 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15911 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15913 * s/openbsd.h (BROKEN_SIGIO): Define.
15914 * unexelf.c (unexec) [__OpenBSD__]:
15915 Don't update the .mdebug section of the Alpha COFF symbol table.
15917 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15919 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15922 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15924 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15925 This fixes some race conditions on the permissions of any newly
15928 * alloc.c (valid_pointer_p): Use pipe, not open.
15929 This fixes some permissions issues when debugging.
15931 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15932 If fchown fails to set both uid and gid, try to set just gid,
15933 as that is sometimes allowed. Adjust the file's mode to eliminate
15934 setuid or setgid bits that are inappropriate if fchown fails.
15936 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15938 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15939 to compare Lisp_Objects.
15940 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15941 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15942 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15944 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15946 * lread.c (read_integer): Unread even EOF character.
15947 (read1): Likewise. Properly record start position of symbol.
15949 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15950 symbol character follows.
15952 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15954 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15955 This works around a problem with the previous change to Fcopy_file.
15956 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15957 and without this change, GCC might complain about discarding
15958 fchown's return value.
15960 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15962 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15964 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15966 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15968 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15970 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15971 it's used from the C level.
15973 * process.c: Use the same condition for POLL_FOR_INPUT in both
15974 keyboard.c and process.c (bug#1858).
15976 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15978 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15979 (Fgnutls_boot): Use it.
15981 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15983 * doc.c (Fsubstitute_command_keys): Revert last change.
15985 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15987 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15988 quotes the next character, and doesn't affect other longer
15989 sequences (bug#8935).
15991 * lread.c (syms_of_lread): Clarify that is isn't only
15992 `eval-buffer' and `eval-defun' that's affected by
15993 `lexical-binding' (bug#8460).
15995 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15997 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15998 bidi redisplay when a line includes both an image and is truncated.
16000 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16002 Fix minor problems found by static checking.
16003 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16004 (elsz): Now a signed constant, not a size_t var. We prefer signed
16005 types to unsigned, to avoid integer comparison confusion. Without
16006 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16007 "cannot optimize loop, the loop counter may overflow", a symptom
16009 * indent.c (Fvertical_motion): Mark locals as initialized.
16010 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16012 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16014 * search.c (Fre_search_backward): Mention `case-fold-search' in
16015 all the re_search_* functions (bug#8138).
16017 * keyboard.c (Fopen_dribble_file): Document when the file is
16020 2011-07-14 Eli Zaretskii <eliz@gnu.org>
16022 * bidi.c (bidi_dump_cached_states): Fix format of displaying
16025 Support bidi reordering of display and overlay strings.
16026 * xdisp.c (compute_display_string_pos)
16027 (compute_display_string_end): Accept additional argument STRING.
16028 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
16029 (reseat_to_string): Initialize bidi_it->string.s and
16030 bidi_it->string.schars.
16031 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16032 NULL (avoids a crash in bidi_paragraph_init).
16033 Initialize itb.string.lstring.
16034 (init_iterator): Call bidi_init_it only of a valid
16035 buffer position was specified. Initialize paragraph_embedding to
16037 (reseat_to_string): Initialize the bidi iterator.
16038 (display_string): If we need to ignore text properties of
16039 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16040 original value of -1 will not work with bidi.)
16041 (compute_display_string_pos): First arg is now struct
16042 `text_pos *'; all callers changed. Support display properties on
16044 (compute_display_string_end): Support display properties on Lisp
16046 (init_iterator, reseat_1, reseat_to_string): Initialize the
16047 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16048 when iterating on a string not from display properties).
16049 (compute_display_string_pos, compute_display_string_end):
16050 Fix calculation of the object to scan. Fixes an error when using
16052 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16053 base_level_stop; instead, set base_level_stop to BEGV.
16054 Fixes crashes in vertical-motion.
16055 (next_element_from_buffer): Improve commentary for when
16056 the iterator is before prev_stop.
16057 (init_iterator): Initialize bidi_p from the default value of
16058 bidi-display-reordering, not from buffer-local value. Use the
16059 buffer-local value only if initializing for buffer iteration.
16060 (handle_invisible_prop): Support invisible properties on strings
16061 that are being bidi-reordered.
16062 (set_iterator_to_next): Support bidi reordering of C strings and
16064 (next_element_from_string): Support bidi reordering of Lisp
16066 (handle_stop_backwards): Support Lisp strings as well.

16532 * alloc.c (mark_buffer):
16533 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
16534 (clone_per_buffer_values): Don't assume that
16535 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
16536 This isn't true in general, and it's particularly not true
16537 if Emacs is configured with --with-wide-int.
16538 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16539 New macros, used in the buffer.c change.

16575 Random fixes. E.g., (random) never returned negative values.
16576 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16577 subseconds part to the entropy, as that's a bit more random.
16578 Prefer signed to unsigned, since the signedness doesn't matter and
16579 in general we prefer signed. When given a limit, use a
16580 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16581 latter isn't right if USE_2_TAGS_FOR_INTS.
16582 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16583 not 0..VALMASK. Don't discard "excess" bits that random () returns.
16585 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
16587 * textprop.c (text_property_stickiness):
16588 Obey Vtext_property_default_nonsticky.

16595 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16596 This is more efficient than Ffile_directory_p and avoids a minor race.
16598 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16600 * buffer.c (Foverlay_put): Say what the return value is
16603 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16604 is a directory before asking whether to use the file name
16606 (barf_or_query_if_file_exists): Make the "File is a directory"
16607 error be more correct.
16609 * fns.c (Frequire): Remove the mention of the .gz files, since
16610 that's installation-specific, but keep the mention of
16611 `get-load-suffixes'.

16615 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

16621 (syms_of_gnutls): Remove duplicate DEFSYM for
16622 Qgnutls_bootprop_verify_hostname_error, an error for
16623 Qgnutls_bootprop_verify_error (which is no longer used).
16625 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16626 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16627 Also (re)move comments that are misplaced or no longer relevant.
16629 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16631 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16690 (syms_of_keymap): Defsubr make-composed-keymap.
16691 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16728 * eval.c (struct backtrace): Simplify and port the data structure.
16729 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16730 signed bit field, as this assumption is not portable and it makes
16731 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16732 "char debug_on_exit : 1" as this is not portable either; instead,
16733 use the portable "unsigned int debug_on_exit : 1". Remove unused
16734 member evalargs. Remove obsolete comments about cc bombing out.
16736 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16944 2011-06-22 Leo Liu <sdl.web@gmail.com>
16946 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16947 Move to minibuffer.el.
16949 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16951 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16952 The following patches are for when GLYPH_DEBUG && !XASSERT.
16953 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16954 * dispnew.c (flush_stdout):
16955 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16956 Mark as externally visible.
16957 * dispnew.c (check_window_matrix_pointers): Now static.
16958 * dispnew.c (window_to_frame_vpos):
16959 * xfns.c (unwind_create_frame):
16960 * xterm.c (x_check_font): Remove unused local.
16961 * scroll.c (CHECK_BOUNDS):
16962 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16963 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16964 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16965 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16966 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16968 (debug_method_add): Use va_list and vsprintf rather than relying
16969 on undefined behavior with wrong number of arguments.
16970 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16971 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16972 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16973 since we're not interested in debugging glyphs with old libraries.
16974 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16975 GCC 4.6.0's static checking.
16977 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16979 Integer overflow and signedness fixes (Bug#8873).

16988 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16989 (x_create_bitmap_from_xpm_data):
16990 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16991 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16993 * xfaces.c (load_pixmap):
16994 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16995 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16996 (.bitmaps_last, struct x_output.icon_bitmap):
16997 Use ptrdiff_t, not int, for bitmap indexes.
16998 (x_allocate_bitmap_record): Check for size overflow.
16999 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17001 Use ptrdiff_t, not int, for overlay counts.
17002 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17003 * editfns.c (overlays_around, get_pos_property):
17004 * textprop.c (get_char_property_and_overlay):
17005 * xdisp.c (next_overlay_change, note_mouse_highlight):
17006 * xfaces.c (face_at_buffer_position):
17007 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17008 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17009 (Fnext_overlay_change, Fprevious_overlay_change)
17010 (mouse_face_overlay_overlaps, Foverlays_in):
17011 Use ptrdiff_t, not int, for sizes.
17012 (overlays_at, overlays_in): Check for size-calculation overflow.
17014 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17016 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17017 (x_session_initialize): Do not assume string length fits in int.
17019 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17020 This is unlikely, but can occur if DPI is outlandish.
17022 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17023 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17025 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17026 * xrdb.c (magic_file_p, search_magic_path):
17027 Omit last arg SUFFIX; it was always 0. All callers changed.
17028 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17030 * xfont.c (xfont_match): Avoid need for strlen.
17032 * xfns.c: Don't assume strlen fits in int.
17033 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17035 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17036 not unsigned long, as we prefer signed integers. All callers changed.
17037 Detect integer overflow in repeat count.
17038 (message_dolog): Don't assume print length fits in 39 bytes.
17039 (display_mode_element): Don't assume strlen fits in int.
17041 * termcap.c: Don't assume sizes fit in int and never overflow.
17042 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17043 (gobble_line): Check for size-calculation overflow.
17045 * minibuf.c (Fread_buffer):
17046 * lread.c (intern, intern_c_string):
17047 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17048 Don't assume string length fits in int.
17050 * keyboard.c (parse_tool_bar_item):
17051 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17053 * font.c: Don't assume string length fits in int.
17054 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17055 Use ptrdiff_t, not int.
17056 (font_intern_prop): Don't assume string length fits in int.
17057 Don't assume integer property fits in fixnum.
17058 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17060 * filelock.c: Fix some buffer overrun and integer overflow issues.
17061 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17062 Reformulate so as not to need the command string.
17063 Invoke gzip -cd rather than gunzip, as it's more portable.
17064 (lock_info_type, lock_file_1, lock_file):
17065 Don't assume pid_t and time_t fit in unsigned long.
17066 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17067 (current_lock_owner): Prefer signed type for sizes.
17068 Use memcpy, not strncpy, where memcpy is what is really wanted.
17069 Don't assume (via atoi) that time_t and pid_t fit in int.
17070 Check for time_t and/or pid_t out of range, e.g., via a network share.
17071 Don't alloca where an auto var works fine.
17073 * fileio.c: Fix some integer overflow issues.
17074 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17075 Don't assume string length fits in int.
17076 (directory_file_name): Don't assume string length fits in long.
17077 (make_temp_name): Don't assume pid fits in int, or that its print
17078 length is less than 20.
17080 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17082 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17084 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17086 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17087 We prefer signed integers, even for size calculations.
17089 * emacs.c: Don't assume string length fits in 'int'.
17090 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17091 (main): Don't invoke strlen when not needed.
17093 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17094 (XD_DEBUG_MESSAGE): Don't waste a byte.
17096 * callproc.c (getenv_internal_1, getenv_internal)
17097 (Fgetenv_internal):
17098 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17100 * lread.c (invalid_syntax): Omit length argument.
17101 All uses changed. This doesn't fix a bug, but it simplifies the
17102 code away from its former Hollerith-constant appearance, and it's
17103 one less 'int' to worry about when looking at integer-overflow issues.
17104 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17106 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17107 This didn't break anything, but it didn't help either.
17108 It's confusing to put a bogus integer in a place where the actual
17109 value does not matter.
17110 (LIST_END_P): Remove unused macro and its bogus comment.
17111 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17113 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17114 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17116 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17117 We prefer signed types, and the value cannot exceed the EMACS_INT
17118 range anyway (because otherwise the length would not be representable).
17119 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17120 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17121 This avoids a GCC warning when WIDE_EMACS_INT.
17123 * indent.c (sane_tab_width): New function.
17124 (current_column, scan_for_column, Findent_to, position_indentation)
17125 (compute_motion): Use it. This is just for clarity.
17126 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17128 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17130 * lisp.h (lint_assume): New macro.
17131 * composite.c (composition_gstring_put_cache):
17132 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17134 * editfns.c, insdel.c:
17135 Omit unnecessary forward decls, to simplify future changes.
17137 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17139 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17141 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17142 Use much-faster test for byte-length change.
17143 Don't assume string byte-length fits in 'int'.
17144 Check that character arg fits in 'int'.
17145 (mapcar1): Declare byte as byte, for clarity.
17147 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17149 * fns.c (concat): Catch string overflow earlier.
17150 Do not rely on integer wraparound.
17152 * dispextern.h (struct it.overlay_strings_charpos)
17153 (struct it.selective): Now EMACS_INT, not int.
17154 * xdisp.c (forward_to_next_line_start)
17155 (back_to_previous_visible_line_start)
17156 (reseat_at_next_visible_line_start, next_element_from_buffer):
17157 Don't arbitrarily truncate the value of 'selective' to int.
17159 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17161 * composite.c: Don't truncate sizes to 'int'.
17162 (composition_gstring_p, composition_reseat_it)
17163 (composition_adjust_point): Use EMACS_INT, not int.
17164 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17165 not EMACS_UINT, for indexes.
17167 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17169 * buffer.c: Include <verify.h>.
17170 (struct sortvec.priority, struct sortstr.priority):
17171 Now EMACS_INT, not int.
17172 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17173 (struct sortstr.size, record_overlay_string)
17174 (struct sortstrlist.size, struct sortlist.used):
17175 Don't truncate size to int.
17176 (record_overlay_string): Check for size-calculation overflow.
17177 (init_buffer_once): Check at compile-time, not run-time.
17179 2011-06-22 Jim Meyering <meyering@redhat.com>
17181 Don't leak an XBM-image-sized buffer
17182 * image.c (xbm_load): Free the image buffer after using it.
17184 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17187 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17188 that Sun C diagnosed.
17189 * fns.c (secure_hash): Fix pointer signedness issue.
17190 * intervals.c (static_offset_intervals): New function.
17191 (offset_intervals): Use it.
17193 2011-06-21 Leo Liu <sdl.web@gmail.com>
17196 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17199 * fns.c (secure_hash): Rename from crypto_hash_function and change
17200 the first arg to accept symbols.
17201 (Fsecure_hash): New primitive.
17202 (syms_of_fns): New symbols.
17204 2011-06-20 Deniz Dogan <deniz@dogan.se>
17206 * process.c (Fset_process_buffer): Clarify return value in
17209 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17211 * dispnew.c (add_window_display_history): Use BVAR.
17213 * xdisp.c (debug_method_add): Use BVAR.
17214 (check_window_end, dump_glyph_matrix, dump_glyph)
17215 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17217 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17220 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17221 check till after the cache is created in init_frame_faces.
17223 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17225 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17227 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17229 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17230 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17231 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17233 Improve buffer-overflow checking (Bug#8873).
17234 * fileio.c (Finsert_file_contents):
17235 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17236 Remove the old (too-loose) buffer overflow checks.
17237 They weren't needed, since make_gap checks for buffer overflow.
17238 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17239 The old code merely checked for Emacs fixnum overflow, and relied
17240 on undefined (wraparound) behavior. The new code avoids undefined
17241 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17243 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17244 Tune. Don't use wider integers than needed. Don't use alloca.
17245 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17247 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17249 * insdel.c, lisp.h (buffer_overflow): New function.
17250 (insert_from_buffer_1, replace_range, replace_range_2):
17251 * insdel.c (make_gap_larger):
17252 * editfns.c (Finsert_char):
17253 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17255 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17257 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17259 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17261 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17262 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17264 * fileio.c: Don't assume EMACS_INT fits in off_t.
17265 (emacs_lseek): New static function.
17266 (Finsert_file_contents, Fwrite_region): Use it.
17267 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17269 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17271 * fns.c: Don't overflow int when computing a list length.
17272 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17273 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17274 truncation on 64-bit hosts. Check for QUIT every
17275 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17276 faster and is responsive enough.
17277 (Flength): Report an error instead of overflowing an integer.
17278 (Fsafe_length): Return a float if the value is not representable
17279 as a fixnum. This shouldn't happen except in contrived situations.
17280 (Fnthcdr, Fsort): Don't assume list length fits in int.
17281 (Fcopy_sequence): Don't assume vector length fits in int.
17283 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17284 (header_size, word_size): New constants.
17285 (allocate_vectorlike): Don't check size overflow here.
17286 (allocate_vector): Check it here instead, since this is the only
17287 caller of allocate_vectorlike that could cause overflow.
17288 Check that the new vector's length is representable as a fixnum.
17290 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17291 The previous code was bogus. For example, next_almost_prime (32)
17292 returned 39, which is undesirable as it is a multiple of 3; and
17293 next_almost_prime (24) returned 25, which is a multiple of 5 so
17294 why was the code bothering to check for multiples of 7?
17296 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17298 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17300 Variadic C functions now count arguments with ptrdiff_t.
17301 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17302 Back then I didn't know that the Emacs coding style prefers signed int.
17303 Also, in the meantime I found a few more instances where arguments
17304 were being counted with int, which may truncate counts on 64-bit
17305 machines, or EMACS_INT, which may be unnecessarily wide.
17306 * lisp.h (struct Lisp_Subr.function.aMANY)
17307 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17308 Arg counts are now ptrdiff_t, not size_t.
17309 All variadic functions and their callers changed accordingly.
17310 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17311 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17312 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17313 * callint.c (Fcall_interactively): Check arg count for overflow,
17314 to avoid potential buffer overrun. Use signed char, not 'int',
17315 for 'varies' array, so that we needn't bother to check its size
17316 calculation for overflow.
17317 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17318 * eval.c (apply_lambda):
17319 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17320 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17321 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17323 * callint.c (Fcall_interactively): Don't use index var as event count.
17325 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17326 * mem-limits.h (SIZE): Remove; no longer used.
17328 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17330 Remove unnecessary casts.
17331 * xterm.c (x_term_init):
17332 * xfns.c (x_set_border_pixel):
17333 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17334 These aren't needed now that we assume ANSI C.
17336 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17337 It's more likely to cause problems (due to unsigned overflow)
17340 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17342 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17344 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17346 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17348 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17350 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17352 GLYPH_CODE_FACE returns EMACS_INT, not int.
17353 * dispextern.h (merge_faces):
17354 * xfaces.c (merge_faces):
17355 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17356 Don't assume EMACS_INT fits in int.
17358 * character.h (CHAR_VALID_P): Remove unused parameter.
17359 * fontset.c, lisp.h, xdisp.c: All uses changed.
17361 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17363 * fns.c (concat): Minor tuning based on overflow analysis.
17364 This doesn't fix any bugs. Use int to hold character, instead
17365 of constantly refetching from Emacs object. Use XFASTINT, not
17366 XINT, for value known to be a character. Don't bother comparing
17367 a single byte to 0400, as it's always less.
17369 * floatfns.c (Fexpt):
17370 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17372 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17375 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17377 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17378 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17379 incorrectly succeed when S was a string, because 4294967386 was
17380 truncated before it was used.
17382 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17383 Otherwise, an out-of-range integer could cause undefined behavior
17386 * composite.c: Use int, not EMACS_INT, for characters.
17387 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17388 EMACS_INT, for values that are known to be in character range.
17389 This doesn't fix any bugs but is the usual style inside Emacs and
17390 may generate better code on 32-bit machines.
17392 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17393 This is for reasons similar to the recent CHAR_STRING fix.
17394 * charset.c (Fencode_char): Check that character arg is actually
17395 a character. Pass an int to ENCODE_CHAR.
17396 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17397 wider than 'int', as a compile-time check to prevent future regressions
17400 * character.c (char_string): Remove unnecessary casts.
17402 Make sure a 64-bit char is never passed to CHAR_STRING.
17403 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17404 by silently ignoring the top 32 bits, allowing some values
17405 that were far too large to be valid characters.
17406 * character.h: Include <verify.h>.
17407 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17408 arguments are no wider than unsigned, as a compile-time check
17409 to prevent future regressions in this area.
17411 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17412 (Fsubst_char_in_region):
17414 * xdisp.c (decode_mode_spec_coding):
17415 Adjust to CHAR_STRING's new requirement.
17416 * editfns.c (Finsert_char, Fsubst_char_in_region):
17417 * fns.c (concat): Check that character args are actually
17418 characters. Without this test, these functions did the wrong
17419 thing with wildly out-of-range values on 64-bit hosts.
17421 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17422 These casts should not be needed on 32-bit hosts, either.
17423 * keyboard.c (read_char):
17424 * lread.c (Fload): Remove casts to unsigned.
17426 * lisp.h (UNSIGNED_CMP): New macro.
17427 This fixes comparison bugs on 64-bit hosts.
17428 (ASCII_CHAR_P): Use it.
17429 * casefiddle.c (casify_object):
17430 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17431 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17432 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17433 * dispextern.h (FACE_FROM_ID):
17434 * keyboard.c (read_char): Use UNSIGNED_CMP.
17436 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17437 not to EMACS_INT, to avoid GCC warning.
17439 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17441 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17442 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17443 isn't needed on 32-bit machines.
17445 * buffer.c (Fgenerate_new_buffer_name):
17446 Use EMACS_INT for count, not int.
17447 (advance_to_char_boundary): Return EMACS_INT, not int.
17449 * data.c (Qcompiled_function): Now static.
17451 * window.c (window_body_lines): Now static.
17453 * image.c (gif_load): Rename local to avoid shadowing.
17455 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17456 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17457 * alloc.c (make_save_value): Integer argument is now of type
17458 ptrdiff_t, not int.
17459 (mark_object): Use ptrdiff_t, not int.
17460 * lisp.h (pD): New macro.
17461 * print.c (print_object): Use it.
17463 * alloc.c: Use EMACS_INT, not int, to count objects.
17464 (total_conses, total_markers, total_symbols, total_vector_size)
17465 (total_free_conses, total_free_markers, total_free_symbols)
17466 (total_free_floats, total_floats, total_free_intervals)
17467 (total_intervals, total_strings, total_free_strings):
17468 Now EMACS_INT, not int. All uses changed.
17469 (Fgarbage_collect): Compute overall total using a double, so that
17470 integer overflow is less likely to be a problem. Check for overflow
17471 when converting back to an integer.
17472 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17473 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17474 These were 'int' variables that could overflow on 64-bit hosts;
17475 they were never used, so remove them instead of repairing them.
17476 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17477 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17478 Previously, this ceilinged at INT_MAX, but that doesn't work on
17480 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17482 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17483 (allocate_vectorlike): Check for ptrdiff_t overflow.
17484 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17485 when a (possibly-narrower) signed value would do just as well.
17486 We prefer using signed arithmetic, to avoid comparison confusion.
17488 * alloc.c: Catch some string size overflows that we were missing.
17489 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17490 for convenience in STRING_BYTES_MAX.
17491 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17492 The definition here is exact; the one in lisp.h was approximate.
17493 (allocate_string_data): Check for string overflow. This catches
17494 some instances we weren't catching before. Also, it catches
17495 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17496 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17497 and ptrdiff_t and EMACS_INT are both 64 bits.
17499 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17500 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17501 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17503 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17505 * alloc.c (Fmake_string): Check for out-of-range init.
17507 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17509 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17511 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17513 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

17516 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17517 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17518 (style_changed_cb): Call update_theme_scrollbar_width and call
17519 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17520 all frames (Bug#8505).
17521 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17522 Call gtk_window_set_resizable if HAVE_GTK3.

17524 and height if HAVE_GTK3 (Bug#8505).
17525 (scroll_bar_width_for_theme): New variable.
17526 (update_theme_scrollbar_width): New function.
17527 (xg_get_default_scrollbar_width): Move code to
17528 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

17531 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17533 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17535 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17537 * frame.c (make_frame): Call other_buffer_safely instead of
17540 * window.c (temp_output_buffer_show): Call display_buffer with
17541 second argument Vtemp_buffer_show_specifiers and reset latter
17542 immediately after the call.
17543 (Vtemp_buffer_show_specifiers): New variable.
17544 (auto_window_vscroll_p, next_screen_context_lines)
17545 (Vscroll_preserve_screen_position): Remove leading asterisks from

18109 value of a `display' property is a "replacing spec".
18110 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18111 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

18141 * gnutls.c: Use Emacs's memory allocators.
18142 Without this change, the gnutls library would invoke malloc etc.
18143 directly, which causes problems on non-SYNC_INPUT hosts, and which
18144 runs afoul of improving memory_full behavior. (Bug#8761)
18145 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18146 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18147 xfree instead of the default malloc, realloc, free.
18148 (Fgnutls_boot): No need to check for memory allocation failure,
18149 since xmalloc does that for us.

18178 need to be updated by these changes.
18179 * fns.c (make_hash_table, maybe_resize_hash_table):
18180 Check for integer overflow with large hash tables.
18181 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18182 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18183 (SXHASH_REDUCE): New macro.
18184 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18185 Use it instead of discarding useful hash info with large hash values.
18186 (sxhash_float): New function.
18187 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18188 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18189 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18190 Rewrite to use FIXNUM_BITS, as this simplifies things.
18191 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18192 Adjust signatures to match updated version of code.
18193 (consing_since_gc): Now EMACS_INT, since a single hash table can
18194 use more than INT_MAX bytes.

18243 Make it possible to run ./temacs.
18245 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18246 syms_of_callproc does the same thing. Remove test for
18247 "initialized", do it in the caller.
18248 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18250 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18252 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18253 (read_minibuf): Use get_minibuffer.
18254 (syms_of_minibuf): Use DEFSYM.
18255 (Qmetadata): New var.
18256 * data.c (Qbuffer): Don't make it static.
18257 (syms_of_data): Use DEFSYM.
18259 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18261 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18262 (CCL_CODE_MIN): New macro.
18264 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18266 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18268 * eval.c (Qdebug): Now static.
18269 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18270 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18271 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18273 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18275 * image.c: Various fixes to ImageMagick code comments.
18276 (Fimagemagick_types): Doc fix.
18278 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18280 Minor fixes prompted by GCC 4.6.0 warnings.
18282 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18284 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18285 (x_clipboard_manager_save_all): Move extern decl to ...
18286 * xterm.h: ... here, so that it can be checked for consistency.
18288 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18290 * xselect.c (x_clipboard_manager_save_frame)
18291 (x_clipboard_manager_save_all): New functions.
18292 (Fx_clipboard_manager_save): Lisp function deleted.
18294 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18295 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18297 * xterm.h: Update prototype.
18299 2011-05-28 William Xu <william.xwl@gmail.com>
18301 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18302 exiting (Bug#8239).
18304 2011-05-28 Jim Meyering <meyering@redhat.com>
18306 Avoid a sign-extension bug in crypto_hash_function.
18307 * fns.c (to_uchar): Define.
18308 (crypto_hash_function): Use it to convert some newly-signed
18309 variables to unsigned, to avoid sign-extension bugs. For example,
18310 without this change, (md5 "truc") would evaluate to
18311 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18312 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18313 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18315 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18317 Integer overflow fixes.
18319 * dbusbind.c: Serial number integer overflow fixes.
18320 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18321 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18322 to hold a serial number that is too large for a fixnum.
18323 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18324 Check for serial numbers out of range. Decode any serial number
18325 that was so large that it became a float. (Bug#8722)
18327 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18328 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18329 Use XFASTINT rather than XUINT when numbers are nonnegative.
18330 (xd_append_arg, Fdbus_method_return_internal):
18331 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18332 arguments, check that Lisp number is nonnegative, rather than
18333 silently wrapping negative numbers around. (Bug#8722)
18334 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18337 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18339 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18341 ccl: Add integer overflow checks.
18342 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18343 (IN_INT_RANGE): New macros.
18344 (ccl_driver): Use them to check for integer overflow when
18345 decoding a CCL program. Many of the new checks are whether XINT (x)
18346 fits in int; it doesn't always, on 64-bit hosts. The new version
18347 doesn't catch all possible integer overflows, but it's an
18348 improvement. (Bug#8719)
18350 * alloc.c (make_event_array): Use XINT, not XUINT.
18351 There's no need for unsigned here.
18353 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18354 This follows up to the 2011-05-06 change that substituted uintptr_t
18355 for EMACS_INT. This case wasn't caught back then.
18357 Rework Fformat to avoid integer overflow issues.
18358 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18359 now (part of C89). Include <verify.h>.
18360 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18361 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18362 (Fformat): Avoid the prepass trying to compute sizes; it was only
18363 approximate and thus did not catch overflow reliably. Instead, walk
18364 through the format just once, formatting and computing sizes as we go,
18365 checking for integer overflow at every step, and allocating a larger
18366 buffer as needed. Keep track separately whether the format is
18367 multibyte. Keep only the most-recently calculated precision, rather
18368 than them all. Record whether each argument has been converted to
18369 string. Use EMACS_INT, not int, for byte and char and arg counts.
18370 Support field widths and precisions larger than INT_MAX. Avoid
18371 sprintf's undefined behavior with conversion specifications such as %#d
18372 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18373 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18374 formatting out-of-range floating point numbers with int
18375 formats. (Bug#8668)
18377 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18379 * data.c: Avoid integer truncation in expressions involving floats.
18380 * data.c: Include <intprops.h>.
18381 (arith_driver): When there's an integer overflow in an expression
18382 involving floating point, convert the integers to floating point
18383 so that the resulting value does not suffer from catastrophic
18384 integer truncation. For example, on a 64-bit host (* 4
18385 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18386 Do not rely on undefined behavior after integer overflow.
18388 merge count_size_as_multibyte, parse_str_to_multibyte
18389 * character.c, character.h (count_size_as_multibyte):
18390 Rename from parse_str_to_multibyte; all uses changed.
18391 Check for integer overflow.
18392 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18393 since it's now a duplicate of the other. This is more of
18394 a character than a buffer op, so better that it's in character.c.
18395 * fns.c, print.c: Adjust to above changes.
18397 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18399 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18401 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18403 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18404 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18405 (x_clipboard_manager_save): Now static.
18406 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18408 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18409 (crypto_hash_function): Now static.
18410 Fix pointer signedness problems. Avoid unnecessary initializations.
18412 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18414 * termhooks.h (Vselection_alist): Make it terminal-local.
18416 * terminal.c (create_terminal): Initialize it.
18418 * xselect.c: Support for clipboard managers.
18419 (Vselection_alist): Move to termhooks.h as terminal-local var.
18420 (LOCAL_SELECTION): New macro.
18421 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18422 (symbol_to_x_atom): Remove gratuitous arg.
18423 (x_handle_selection_request, lisp_data_to_selection_data)
18424 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18425 (x_own_selection, x_get_local_selection, x_convert_selection):
18426 New arg, specifying work frame. Use terminal-local Vselection_alist.
18427 (some_frame_on_display): Delete unused function.
18428 (Fx_own_selection_internal, Fx_get_selection_internal)
18429 (Fx_disown_selection_internal, Fx_selection_owner_p)
18430 (Fx_selection_exists_p): New optional frame arg.
18431 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18432 (x_handle_selection_clear): Don't treat other terminals with the
18433 same keyboard specially. Use the terminal-local Vselection_alist.
18434 (x_clear_frame_selections): Use Frun_hook_with_args.
18436 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18438 * xterm.h: Add support for those atoms.
18440 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18442 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18443 (converted_selections, conversion_fail_tag): New global variables.
18444 (x_selection_request_lisp_error): Free the above.
18445 (x_get_local_selection): Remove unnecessary code.
18446 (x_reply_selection_request): Args changed; handle arbitrary array
18447 of converted selections stored in converted_selections.
18448 Separate the XChangeProperty and SelectionNotify steps.
18449 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18450 (x_convert_selection): New function.
18451 (x_handle_selection_event): Simplify.
18452 (x_get_foreign_selection): Don't ignore incoming requests while
18453 waiting for an answer; this will fail when we implement
18454 SAVE_TARGETS, and seems unnecessary anyway.
18455 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18456 (Vx_sent_selection_functions): Doc fix.
18458 2011-05-26 Leo Liu <sdl.web@gmail.com>
18460 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18462 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18464 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18466 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18467 for fringe update if it has periodic bitmap.
18468 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18469 and fringe_bitmap_periodic_p.
18471 * fringe.c (get_fringe_bitmap_data): New function.
18472 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18473 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18474 row. Mark glyph row for fringe update if periodicity changed.
18476 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18477 for fringe update unless it has periodic bitmap.
18479 2011-05-25 Kenichi Handa <handa@m17n.org>
18481 * xdisp.c (get_next_display_element): Set correct it->face_id for
18482 a static composition.
18484 2011-05-24 Leo Liu <sdl.web@gmail.com>
18487 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18489 * fns.c (crypto_hash_function, Fsha1): New function.
18490 (Fmd5): Use crypto_hash_function.
18491 (syms_of_fns): Add Ssha1.
18493 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18495 * gnutls.c: Remove unused macros.
18496 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18497 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18498 Remove macros that are defined and never used.
18499 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18501 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18503 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18504 (Fx_get_selection_internal): Minor cleanup.
18505 (Fx_own_selection_internal): Rename arguments for consistency with
18508 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18510 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18512 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18514 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18516 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18518 * dispnew.c (scrolling_window): Don't exclude the case that the
18519 last enabled row in the desired matrix touches the bottom boundary.
18521 2011-05-21 Glenn Morris <rgm@gnu.org>
18523 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18524 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18525 and add some more files.
18527 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18529 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18530 report_file_error introduced by the change from 2011-05-07.
18532 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18534 * systime.h (Time): Define only if emacs is defined.
18535 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18536 where the include path doesn't have X11/X.h by default. See
18537 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18539 2011-05-20 Kenichi Handa <handa@m17n.org>
18541 * composite.c (find_automatic_composition): Fix previous change.
18543 2011-05-20 Glenn Morris <rgm@gnu.org>
18545 * lisp.mk: New file, split from Makefile.in.
18546 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18547 (shortlisp): Remove.
18548 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18550 2011-05-19 Glenn Morris <rgm@gnu.org>
18552 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18553 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18554 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18555 (lisp): Set the order to that of loadup.el.
18556 (shortlisp): Make it a copy of $lisp.
18557 (SOME_MACHINE_LISP): Remove.
18558 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18559 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18561 2011-05-18 Kenichi Handa <handa@m17n.org>
18563 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18564 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18565 (find_automatic_composition): Mostly rewrite for efficiency.
18567 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18569 * makefile.w32-in: Update dependencies.
18571 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18573 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18574 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18576 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18578 Fix some integer overflow issues, such as string length overflow.
18580 * insdel.c (count_size_as_multibyte): Check for string overflow.
18582 * character.c (lisp_string_width): Check for string overflow.
18583 Use EMACS_INT, not int, for string indexes and lengths; in
18584 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18585 the resulting string length overflows an EMACS_INT; instead,
18586 report a string overflow if no precision given. When checking for
18587 precision exhaustion, use a check that cannot possibly have
18588 integer overflow. (Bug#8675)
18589 * character.h (lisp_string_width): Adjust to new signature.
18591 * alloc.c (string_overflow): New function.
18592 (Fmake_string): Use it. This doesn't change behavior, but saves
18593 a few bytes and will simplify future changes.
18594 * character.c (string_escape_byte8): Likewise.
18595 * lisp.h (string_overflow): New decl.
18597 Fixups, following up to the user-interface timestamp change.
18598 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18599 for UI timestamps, instead of unsigned long.
18600 * msdos.c (mouse_get_pos): Likewise.
18601 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18602 * w32gui.h (Time): Define by including "systime.h" rather than by
18603 declaring it ourselves. (Bug#8664)
18605 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18606 * image.c (clear_image_cache): Likewise.
18608 * term.c (term_mouse_position): Don't assume time_t wraparound.
18610 Be more systematic about user-interface timestamps.
18611 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18612 and sometimes 'EMACS_UINT', to represent these timestamps.
18613 This change causes it to use 'Time' uniformly, as that's what X uses.
18614 This makes the code easier to follow, and makes it easier to catch
18615 integer overflow bugs such as Bug#8664.
18616 * frame.c (Fmouse_position, Fmouse_pixel_position):
18617 Use Time, not unsigned long, for user-interface timestamps.
18618 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18619 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18620 * keyboard.h (last_event_timestamp): Likewise.
18621 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18622 * menu.h (xmenu_show): Likewise.
18623 * term.c (term_mouse_position): Likewise.
18624 * termhooks.h (struct input_event.timestamp): Likewise.
18625 (struct terminal.mouse_position_hook): Likewise.
18626 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18627 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18628 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18629 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18630 what it was before.
18631 * menu.h, termhooks.h: Include "systime.h", for Time.
18633 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18634 Don't assume that the difference between two unsigned long values
18635 can fit into an integer. At this point, we know button_down_time
18636 <= event->timestamp, so the difference must be nonnegative, so
18637 there's no need to cast the result if double-click-time is
18638 nonnegative, as it should be; check that it's nonnegative, just in
18639 case. This bug is triggered when events are more than 2**31 ms
18640 apart (about 25 days). (Bug#8664)
18642 * xselect.c (last_event_timestamp): Remove duplicate decl.
18643 (x_own_selection): Remove needless cast to unsigned long.
18645 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18646 that always fit in int. Use a sentinel instead of a counter, to
18647 avoid a temp and to allay GCC's concerns about possible int overflow.
18648 * frame.h (struct frame): Use int for menu_bar_items_used
18649 instead of EMACS_INT, since it always fits in int.
18651 * menu.c (grow_menu_items): Check for int overflow.
18653 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18655 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18656 Before, the code was not consistent. These values cannot exceed
18657 2**31 - 1 so there's no need to make them unsigned.
18658 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18659 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18660 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18662 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18664 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18665 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18666 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18667 presumably because the widths might not match.
18669 * window.c (size_window): Avoid needless test at loop start.
18671 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18673 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18675 2011-05-12 Drew Adams <drew.adams@oracle.com>
18677 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18679 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18681 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18682 `width' to `bar_area_x' and `bar_area_width', respectively.
18683 (x_scroll_run): Take account of fringe background extension.
18685 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18686 Rename local vars `left' and `width' to `bar_area_x' and
18687 `bar_area_width', respectively.
18688 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18689 background extension.
18691 2011-05-10 Jim Meyering <meyering@redhat.com>
18693 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18695 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18697 * image.c (Finit_image_library): Return t for built-in image types,
18698 like pbm and xbm. (Bug#8640)
18700 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18702 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18704 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18706 * w32console.c (Fset_screen_color): Doc fix.
18707 (Fget_screen_color): New function.
18708 (syms_of_ntterm): Defsubr it.
18710 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18711 unlink the temporary file if Fcall_process didn't create it in the
18713 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18714 child process will be redirected to a file specified with `:file'.
18715 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18716 cue to call_process_cleanup not to close that handle.
18718 2011-05-07 Ben Key <bkey76@gmail.com>
18720 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18721 one of two shell specific rules, either bootstrap-temacs-CMD or
18722 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18723 to the previous implementation of the bootstrap-temacs rule.
18724 The bootstrap-temacs-CMD rule is similar to the previous
18725 implementation of the bootstrap-temacs rule except that it
18726 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18729 These changes, along with some changes to nt/configure.bat,
18730 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18731 earlier fix to add support for --cflags and --ldflags options
18732 that include quotes so that it works whether make uses cmd or
18735 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18737 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18738 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18740 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18741 a string. Handle both cases.
18742 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18743 (Fdbus_register_method): Use Qinvalid_function.
18745 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18747 * makefile.w32-in: Update dependencies.
18748 (LISP_H): Add inttypes.h and stdin.h.
18749 (PROCESS_H): Add unistd.h.
18751 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18753 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18754 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18756 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18758 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18760 * term.c (vfatal): Remove stray call to va_end.
18761 It's not needed and the C Standard doesn't allow it here anyway.
18763 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18764 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18766 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18769 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18771 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18773 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18775 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18777 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18779 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18780 * charset.c (Fdefine_charset_internal): Don't initialize
18781 charset.code_space[15]. The value was garbage, on hosts with
18782 32-bit int (Bug#8600).
18784 * lread.c (read_integer): Be more consistent with string-to-number.
18785 Use string_to_number to do the actual conversion; this avoids
18786 rounding errors and fixes some other screwups. Without this fix,
18787 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18788 (digit_to_number): Move earlier, for benefit of read_integer.
18789 Return -1 if the digit is out of range for the base, -2 if it is
18790 not a digit in any supported base. (Bug#8602)
18792 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18794 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18795 to match comment at start of function. This also removes a
18796 GCC warning about overflow in a 32+64-bit port.
18798 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18800 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18801 Reported by Stefan Monnier in
18802 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18803 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18804 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18806 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18807 (EMACS_UINTPTR): Likewise, with uintptr_t.
18809 * lisp.h: Prefer 64-bit EMACS_INT if available.
18810 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18811 on 32-bit hosts that have 64-bit int, so that they can access
18813 However, temporarily disable this change unless the temporary
18814 symbol WIDE_EMACS_INT is defined.
18816 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18818 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18819 This removes an assumption that EMACS_INT and long are the same
18820 width as pointers. The assumption is true for Emacs porting targets
18821 now, but we want to make other targets possible.
18822 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18823 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18824 In the rest of the code, change types of integers that hold casted
18825 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18826 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18827 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18828 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18829 No need to cast type when ORing.
18830 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18831 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18832 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18833 assume EMACS_INT is the same width as char *.
18834 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18835 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18836 Remove no-longer-needed casts.
18837 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18838 (xg_tool_bar_help_callback, xg_make_tool_item):
18839 Use EMACS_INTPTR to hold an integer
18840 that will be cast to void *; this can avoid a GCC warning
18841 if EMACS_INT is not the same width as void *.
18842 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18843 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18844 (current_message_1, set_message_1):
18845 Use a local to convert to proper width without a cast.
18846 * xmenu.c (dialog_selection_callback): Likewise.
18848 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18849 Also, don't assume VALBITS / RAND_BITS is less than 5,
18850 and don't rely on undefined behavior when shifting a 1 left into
18852 * lisp.h (get_random): Change signature to match.
18854 * lread.c (hash_string): Use size_t, not int, for hash computation.
18855 Normally we prefer signed values; but hashing is special, because
18856 it's better to use unsigned division on hash table sizes so that
18857 the remainder is nonnegative. Also, size_t is the natural width
18858 for hashing into memory. The previous code used 'int', which doesn't
18859 retain enough info to hash well into very large tables.
18860 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18862 * dbusbind.c: Don't possibly lose pointer info when converting.
18863 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18864 Use XPNTR rather than XHASH, so that the high-order bits of
18865 the pointer aren't lost when converting through void *.
18867 * eval.c (Fautoload): Don't double-shift a pointer.
18869 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18871 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18873 * gnutls.c (DEF_GNUTLS_FN):
18874 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18876 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18878 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18881 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18883 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18884 New version that can reserve upto 2GB of heap space.
18886 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18888 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

18892 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18893 `gnutls_certificate_set_x509_key_file'.
18895 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18897 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18898 Update dependencies.
18900 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18902 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18903 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18904 Remove unused parameter `fildes'.
18905 * process.c (read_process_output, send_process): Don't pass it.
18907 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18909 Fix previous change: the library cache is defined in w32.c.
18910 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18911 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18913 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18915 Implement dynamic loading of GnuTLS on Windows.
18917 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18918 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18919 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18922 * gnutls.c (Qgnutls_dll): Define.
18923 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18924 (gnutls_*): Declare function pointers.
18925 (init_gnutls_functions): New function to initialize function pointers.

18928 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18929 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18930 (emacs_gnutls_write, emacs_gnutls_read)
18931 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18932 (Fgnutls_available_p): New function.
18933 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18934 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18935 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18937 * image.c: Include w32.h.
18938 (Vimage_type_cache): Delete.
18939 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18940 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18941 (w32_delayed_load): Move to w32.c.
18943 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18945 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18946 (w32_delayed_load): Move from image.c. When loading a library, record
18947 its filename in the :loaded-from property of the library id.
18948 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18949 Initialize and staticpro them.
18950 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18952 * process.c: Include lisp.h before w32.h, not after.
18953 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18954 instead of gnutls_record_check_pending.
18956 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18958 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18960 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18961 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18964 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18966 * xterm.c (x_set_frame_alpha): Do not set property on anything
18967 else than FRAME_X_OUTER_WINDOW (Bug#8608).

18985 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18987 * callproc.c: Indentation fixup.
18989 * sysdep.c (wait_for_termination_1): Make static.
18990 (wait_for_termination, interruptible_wait_for_termination):
18991 Move after wait_for_termination_1.
18993 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18995 * sysdep.c (interruptible_wait_for_termination): New function
18996 which is like wait_for_termination, but allows keyboard
18999 * callproc.c (Fcall_process): Add (:file "file") as an option for
19001 (Fcall_process_region): Ditto.
19003 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19005 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19006 rather than `XVECTOR (FOO)->size'.
19008 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19009 inttypes.h, as a gnulib replacement is used if it not available in
19012 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19014 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19015 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19016 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19018 * coding.c (coding_alloc_by_realloc): Error out if destination
19019 will grow beyond MOST_POSITIVE_FIXNUM.
19020 (decode_coding_emacs_mule): Abort if there isn't enough place in
19021 charbuf for the composition carryover bytes. Reserve an extra
19022 space for up to 2 characters produced in a loop.
19023 (decode_coding_iso_2022): Abort if there isn't enough place in
19024 charbuf for the composition carryover bytes.

19029 aborting when %lld or %lll format is passed.
19030 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19031 %llo or %llx format is passed. (Bug#8545)
19033 * window.c (window_scroll_line_based): Use a marker instead of
19034 simple variables to record original value of point. (Bug#7952)
19036 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19037 produced by %s or %c overflows available buffer space. (Bug#8545)
19039 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19041 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19042 (SIZE_MAX): Move defn after all includes, as they might #define it.
19044 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19046 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19048 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

19051 (command_loop_1): Run `delayed-warnings-hook'
19052 if Vdelayed_warnings_list is non-nil.

19056 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19058 * doprnt.c (doprnt): Don't return value smaller than the buffer
19059 size if the message was truncated. (Bug#8545).
19061 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19063 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19064 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19066 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19068 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19070 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19072 * makefile.w32-in: Update dependencies.
19074 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19076 Improve `doprnt' and its usage. (Bug#8545)
19077 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19078 `format_end'. Remove support for %l as a conversion specifier.
19079 Don't use xrealloc. Improve diagnostics when the %l size modifier
19080 is used. Update the commentary.
19082 * eval.c (verror): Simplify calculation of size_t.
19084 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19087 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19089 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19092 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19094 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19095 This makes this file independent of the recent pseudovector change.
19097 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19099 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19101 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19102 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19103 Remove unused local.
19104 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19106 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19107 GCC 4.6.0 optimizes based on type-based alias analysis.
19108 For example, if b is of type struct buffer * and v of type struct
19109 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19110 != &v->size, and therefore "v->size = 1; b->size = 2; return
19111 v->size;" must therefore return 1. This assumption is incorrect
19112 for Emacs, since it type-puns struct Lisp_Vector * with many other
19113 types. To fix this problem, this patch adds a new type struct
19114 vectorlike_header that documents the constraints on layout of vectors
19115 and pseudovectors, and helps optimizing compilers not get fooled
19116 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19117 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19118 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19120 (XSETPVECTYPE): Rewrite in terms of new macro.
19121 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19122 This is a bit clearer, and further avoids the possibility of
19123 undesirable aliasing.
19124 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19125 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19126 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19127 since Lisp_Subr is a special case (no "next" field).
19128 (ASIZE): Now uses header.size rather than size.
19129 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19130 to avoid the hassle of writing XVECTOR (foo)->header.size.
19131 (struct vectorlike_header): New type.
19132 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19133 object, to help avoid aliasing.
19134 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19135 (SUBRP): Likewise, since Lisp_Subr is a special case.
19136 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19137 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19138 (struct Lisp_Hash_Table): Combine first two members into a single
19139 struct vectorlike_header member. All uses of "size" and "next" members
19140 changed to be "header.size" and "header.next".
19141 * buffer.h (struct buffer): Likewise.
19142 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19143 * frame.h (struct frame): Likewise.
19144 * process.h (struct Lisp_Process): Likewise.
19145 * termhooks.h (struct terminal): Likewise.
19146 * window.c (struct save_window_data, struct saved_window): Likewise.
19147 * window.h (struct window): Likewise.
19148 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19149 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19150 * buffer.c (init_buffer_once): Likewise.
19151 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19153 * process.c (Fformat_network_address): Use local var for size,
19156 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19158 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19159 * data.c (atof): Remove decl; no longer used or needed.
19160 (digit_to_number): Move to lread.c.
19161 (Fstring_to_number): Use new string_to_number function, to be
19162 consistent with how the Lisp reader treats infinities and NaNs.
19163 Do not assume that floating-point numbers represent EMACS_INT
19164 without losing information; this is not true on most 64-bit hosts.
19165 Avoid double-rounding errors, by insisting on integers when
19166 parsing non-base-10 numbers, as the documentation specifies.
19167 * lisp.h (string_to_number): New decl, replacing ...
19168 (isfloat_string): Remove.
19169 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19170 (read1): Do not accept +. and -. as integers; this
19171 appears to have been a coding error. Similarly, do not accept
19172 strings like +-1e0 as floating point numbers. Do not report
19173 overflow for integer overflows unless the base is not 10 which
19174 means we have no simple and reliable way to continue.
19175 Break out the floating-point parsing into a new
19176 function string_to_number, so that Fstring_to_number parses
19177 floating point numbers consistently with the Lisp reader.
19178 (digit_to_number): Move here from data.c. Make it static inline.
19179 (E_CHAR, EXP_INT): Remove, replacing with ...
19180 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19181 (string_to_number): New function, replacing isfloat_string.
19182 This function checks for valid syntax and produces the resulting
19183 Lisp float number too. Rework it so that string-to-number
19184 no longer mishandles examples like "1.0e+". Use strtoumax,
19185 so that overflow for non-base-10 numbers is reported only when
19186 there's no portable and simple way to convert to floating point.
19188 * textprop.c (set_text_properties_1): Rewrite for clarity,
19189 and to avoid GCC warning about integer overflow.
19191 * intervals.h (struct interval): Use EMACS_INT for members
19192 where EMACS_UINT might cause problems. See
19193 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19194 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19195 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19197 (offset_intervals): Tell GCC not to worry about length overflow
19198 when negating a negative length.
19200 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19201 (overrun_check_free): Likewise.
19203 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19204 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19207 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19208 (gnutls_make_error): Rename local to avoid shadowing.
19209 (gnutls_emacs_global_deinit): ifdef out; not used.
19210 (Fgnutls_boot): Use const for pointer to readonly storage.
19211 Comment out unused local. Fix pointer signedness problems.
19213 * lread.c (openp): Don't stuff size_t into an 'int'.
19214 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19215 about possible signed overflow.
19217 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19218 (GDK_KEY_g): Don't define if already defined.
19219 (xg_prepare_tooltip): Avoid pointer signedness problem.
19220 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19222 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19223 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19225 * xfns.c (Fx_window_property): Simplify a bit,
19226 to make a bit faster and to avoid GCC 4.6.0 warning.
19227 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19229 * fns.c (internal_equal): Don't assume size_t fits in int.
19231 * alloc.c (compact_small_strings): Tighten assertion a little.
19233 Replace pEd with more-general pI, and fix some printf arg casts.
19234 * lisp.h (pI): New macro, generalizing old pEd macro to other
19235 conversion specifiers. For example, use "...%"pI"d..." rather
19236 than "...%"pEd"...".
19237 (pEd): Remove. All uses replaced with similar uses of pI.
19238 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19239 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19240 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19241 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19242 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19243 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19244 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19246 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19247 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19248 * print.c (safe_debug_print, print_object): Likewise.
19249 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19251 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19252 avoiding the 0 flag, which is not portable.
19253 * process.c (Fmake_network_process): Use pI to avoid cast.
19254 * region-cache.c (pp_cache): Likewise.
19255 * xdisp.c (decode_mode_spec): Likewise.
19256 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19257 behavior on 64-bit hosts with printf arg.
19258 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19259 (x_stop_queuing_selection_requests): Likewise.
19260 (x_get_window_property): Don't truncate byte count to an 'int'
19263 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19264 here, since it parses constructs like leading '-' and spaces,
19265 which are not wanted; and it overflows with large numbers.
19266 Instead, simply match F[0-9]+, which is what is wanted anyway.
19268 * alloc.c: Remove unportable assumptions about struct layout.
19269 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19270 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19271 (allocate_vectorlike, make_pure_vector): Use the new macros,
19272 plus offsetof, to remove unportable assumptions about struct layout.
19273 These assumptions hold on all porting targets that I know of, but
19274 they are not guaranteed, they're easy to remove, and removing them
19275 makes further changes easier.
19277 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19278 This doesn't fix a bug but makes the code clearer.
19279 (string_overrun_cookie): Now const. Use initializers that
19280 don't formally overflow signed char, to avoid warnings.
19281 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19282 can cause Emacs to crash when string overrun checking is enabled.
19283 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19284 multiple of sizeof (EMACS_INT); it need not be, if
19285 alignof(EMACS_INT) < sizeof (EMACS_INT).
19286 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19288 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19295 supposed to be handshaking. (Bug#8556)
19296 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19298 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

19304 matches the current signal symbol.
19306 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19308 * alloc.c (check_sblock, check_string_bytes)
19309 (check_string_free_list): Convert to standard C.
19311 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19313 * w32.c (emacs_gnutls_push): Fix typo.
19315 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19317 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19318 "cast to pointer from integer of different size".
19320 Improve doprnt and its use in verror. (Bug#8545)
19321 * doprnt.c (doprnt): Document the set of format control sequences
19322 supported by the function. Use SAFE_ALLOCA instead of always
19325 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19326 is one byte too soon. Don't use xrealloc; instead xfree and
19329 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19331 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19334 * gnutls.c: Renamed global_initialized to
19335 gnutls_global_initialized. Added internals for the
19336 :verify-hostname-error, :verify-error, and :verify-flags
19337 parameters of `gnutls-boot' and documented those parameters in the
19338 docstring. Start callback support.
19339 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19340 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19341 on error. Return error code.

19343 (emacs_gnutls_read): Likewise.
19344 (Fgnutls_boot): Return handshake error code.
19345 (emacs_gnutls_handle_error): New function.

19401 changes in globals.h immediately force recompilation.
19402 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19403 $(CURDIR)/s/ms-w32.h.

19408 <char-direction-table>: Deleted.
19410 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19412 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19413 * doprnt.c: Include limits.h.
19414 (SIZE_MAX): New macro.
19415 (doprnt): Return a size_t value. 2nd arg is now size_t.
19416 Many local variables are now size_t instead of int or unsigned.
19417 Improve overflow protection. Support `l' modifier for integer
19418 conversions. Support %l conversion. Don't assume an EMACS_INT
19419 argument for integer conversions and for %c.
19421 * lisp.h (doprnt): Restore prototype.
19423 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19424 $(SRC)/character.h.
19426 * Makefile.in (base_obj): Add back doprnt.o.
19428 * deps.mk (doprnt.o): Add back prerequisites.
19429 (callint.o): Depend on character.h.
19431 * eval.c (internal_lisp_condition_case): Include the handler
19432 representation in the error message.
19433 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19434 when breaking from the loop.
19436 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19438 * callint.c (Fcall_interactively): When displaying error message
19439 about invalid control letter, pass the character's codepoint, not
19440 a pointer to its multibyte form. Improve display of the character
19441 in octal and display also its hex code.
19443 * character.c (char_string): Use %x to display the (unsigned)
19444 codepoint of an invalid character, to avoid displaying a bogus
19447 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19448 `error', not SYMBOL_NAME itself.
19450 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19451 character arguments to `error'.
19453 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19454 to `error' in error message about FINAL_CHAR argument. Make sure
19455 FINAL_CHAR is a character, and use %c when it is passed as
19456 argument to `error'.

19520 Define only if needed.
19522 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
19523 by pacifying GCC about it. Maybe it's time to retire it?
19524 * xfaces.c (USG, __TIMEVAL__): Likewise.
19526 * dispextern.h (struct redisplay_interface): Rename param
19527 to avoid shadowing.
19528 * termhooks.h (struct terminal): Likewise.
19529 * xterm.c (xembed_send_message): Likewise.
19531 * insdel.c (make_gap_smaller): Define only if
19532 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
19534 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
19537 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
19538 so that we aren't warned about unused symbols.
19540 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
19542 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
19544 * xfns.c (x_real_positions): Mark locals as initialized.
19546 * xmenu.c (xmenu_show): Don't use uninitialized vars.
19548 * xterm.c: Fix problems found by static analysis with other toolkits.
19549 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
19550 (x_dispatch_event): Declare static if USE_GTK, and
19551 define if USE_GTK || USE_X_TOOLKIT.
19552 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
19553 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
19554 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
19555 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
19557 * xmenu.c (menu_help_callback): Pointer type fixes.
19558 Use const pointers when pointing at readonly data. Avoid pointer
19559 signedness clashes.

20000 * lisp.h: Remove these decls.
20002 * buffer.c (buffer_count): Remove unused var.
20004 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
20005 so that it's not optimized away.
20006 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
20007 * dispextern.h (bidi_dump_cached_states): Remove, since it's
20008 exported only to the debugger.
20010 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
20011 * atimer.h (run_all_atimers): Remove; not exported.
20013 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20014 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20015 was inaccessible from Lisp.
20016 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20017 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20019 alloc.c: Import and export fewer symbols, and remove unused items.
20020 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20022 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20023 it's not optimized away by whole-program optimization.
20024 (message_enable_multibyte, free_misc): Remove.
20025 (catchlist, handlerlist, mark_backtrace):
20026 Declare only if BYTE_MARK_STACK.
20027 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
20028 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
20029 (message_enable_multibyte): Remove decl.
20030 (free_misc, interval_free_list, float_block, float_block_index):
20031 (n_float_blocks, float_free_list, cons_block, cons_block_index):
20032 (cons_free_list, last_marked_index):
20034 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
20035 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20036 (mark_backtrace): Define only if BYTE_MARK_STACK.
20037 * xdisp.c (message_enable_multibyte): Now static.
20039 Declare Lisp_Object Q* variables to be 'static' if not exported.
20040 This makes it easier for human readers (and static analyzers)
20041 to see whether these variables are used from other modules.
20042 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20043 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
20044 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
20045 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:

20047 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
20048 * xmenu.c, xselect.c:
20049 Declare Q* vars static if they are not used in other modules.
20050 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
20051 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
20052 Remove decls of unexported vars.
20053 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20055 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20057 Make Emacs functions such as Fatom 'static' by default.
20058 This makes it easier for human readers (and static analyzers)
20059 to see whether these functions can be called from other modules.
20060 DEFUN now defines a static function. To make the function external
20061 so that it can be used in other C modules, use the new macro DEFUE.
20062 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20063 (Finit_image_library):
20064 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20065 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20066 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20067 Remove decls, since these functions are now static.
20068 (Funintern, Fget_internal_run_time): New decls, since these functions
20069 were already external.
20071 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
20072 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
20073 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

20078 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
20079 Mark functions with DEFUE instead of DEFUN,
20080 if they are used in other modules.
20081 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20082 decls for now-static functions.
20083 * buffer.h (Fdelete_overlay): Remove decl.
20084 * callproc.c (Fgetenv_internal): Mark as internal.
20085 * composite.c (Fremove_list_of_text_properties): Remove decl.

20091 (Funintern): Remove extern decl; now in .h file where it belongs.
20092 * fileio.c (Fmake_symbolic_link): New forward static decl.
20093 * image.c (Finit_image_library): New forward static decl.
20094 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20095 * intervals.h (Fprevious_property_change):
20096 (Fremove_list_of_text_properties): Remove decls.
20097 * keyboard.c (Fthis_command_keys): Remove decl.
20098 (Fcommand_execute): New forward static decl.
20099 * keymap.c (Flookup_key): New forward static decl.
20100 (Fcopy_keymap): Now static.
20101 * keymap.h (Flookup_key): Remove decl.
20102 * process.c (Fget_process): New forward static decl.
20103 (Fprocess_datagram_address): Mark as internal.

20116 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
20119 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20121 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20122 when at ZV. (Bug#8487)
20124 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20126 * charset.c (Fclear_charset_maps): Use xfree instead of free.
20128 * keyboard.c (parse_tool_bar_item): Likewise.
20129 * sound.c (sound_cleanup, alsa_close): Likewise.
20130 * termcap.c (tgetent): Likewise.
20131 * xfns.c (x_default_font_parameter): Likewise.
20132 * xsettings.c (read_and_apply_settings): Likewise.
20134 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20135 (overrun_check_free): Protoize.
20137 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20139 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20140 since callers should never pass a negative size.
20141 Change the signature to match that of plain 'read' and 'write'; see
20142 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20143 * lisp.h: Update prototypes of emacs_write and emacs_read.
20145 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20147 * xdisp.c (redisplay_window): Don't try to determine the character
20148 position of the scroll margin if the window start point w->startp
20149 is outside the buffer's accessible region. (Bug#8468)
20151 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20153 Fix write-region and its subroutines for buffers > 2GB.
20154 * fileio.c (a_write, e_write): Modify declaration of arguments and
20155 local variables to support buffers larger than 2GB.
20156 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20158 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20159 argument, local variables, and return value.
20161 * lisp.h: Update prototypes of emacs_write and emacs_read.
20163 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20165 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20167 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20169 Fix more problems found by GCC 4.6.0's static checks.
20171 * xdisp.c (vmessage): Use a better test for character truncation.
20173 * charset.c (load_charset_map): <, not <=, for optimization,
20174 and to avoid potential problems with integer overflow.
20175 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20176 * casetab.c (set_identity, shuffle): Likewise.
20177 * editfns.c (Fformat): Likewise.
20178 * syntax.c (skip_chars): Likewise.
20180 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20181 This also lets GCC 4.6.0 generate slightly better loop code.
20183 * callint.c (Fcall_interactively): <, not <=, for optimization.
20184 (Fcall_interactively): Count the number of arguments produced,
20185 not the number of arguments given. This is simpler and lets GCC
20186 4.6.0 generate slightly better code.
20188 * ftfont.c: Distingish more carefully between FcChar8 and char.
20189 The previous code passed unsigned char * to a functions like
20190 strlen and xstrcasecmp that expect char *, which does not
20191 conform to the C standard.
20192 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20193 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20194 char * when the C standard requires it.
20196 * keyboard.c (read_char): Remove unused var.
20198 * eval.c: Port to Windows vsnprintf (Bug#8435).
20199 Include <limits.h>.
20200 (SIZE_MAX): Define if the headers do not.
20201 (verror): Do not give up if vsnprintf returns a negative count.
20202 Instead, grow the buffer. This ports to Windows vsnprintf, which
20203 does not conform to C99. Problem reported by Eli Zaretskii.
20204 Also, simplify the allocation scheme, by avoiding the need for
20205 calling realloc, and removing the ALLOCATED variable.
20207 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20209 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20210 But keep the doprint source code for now, as we might revamp it
20211 and use it again (Bug#8435).
20212 * lisp.h (doprnt): Remove.
20213 * Makefile.in (base_obj): Remove doprnt.o.
20214 * deps.mk (doprnt.o): Remove.
20216 error: Print 32- and 64-bit integers portably (Bug#8435).
20217 Without this change, on typical 64-bit hosts error ("...%d...", N)
20218 was used to print both 32- and 64-bit integers N, which relied on
20219 undefined behavior.
20220 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20221 * lisp.h (error, verror): Mark as printf-like functions.
20222 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20223 Report overflow in size calculations when allocating printf buffer.
20224 Do not truncate output string at its first null byte.
20225 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20226 Truncate the output at a character boundary, since vsnprintf does not
20228 * charset.c (check_iso_charset_parameter): Convert internal
20229 character to string before calling 'error', since %c now has the
20231 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20232 overflow when computing char to be passed to 'error'. Do not
20233 pass Lisp_Object to 'error'; pass the integer instead.
20234 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20235 formatted with plain %d.
20237 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20239 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20241 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20243 * xterm.c (x_catch_errors): Remove duplicate declaration.
20245 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20247 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20249 2011-04-10 Jim Meyering <meyering@redhat.com>
20251 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20252 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20253 return ssize_t not "int", and use size_t as the buffer length.
20254 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20255 * gnutls.h: Update declarations.
20256 * process.c (read_process_output): Use ssize_t, to match.
20257 (send_process): Likewise.
20259 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20261 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20263 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20265 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20266 Use unsigned char, to match FcChar8 type definition.
20268 * xterm.c (handle_one_xevent):
20269 * xmenu.c (create_and_show_popup_menu):
20270 * xselect.c (x_decline_selection_request)
20271 (x_reply_selection_request): Avoid type-punned deref of X events.
20273 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20275 Fix some uses of `int' instead of EMACS_INT.
20276 * search.c (string_match_1, fast_string_match)
20277 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20278 (scan_buffer, find_next_newline_no_quit)
20279 (find_before_next_newline, search_command, Freplace_match)
20280 (Fmatch_data): Make some `int' variables be EMACS_INT.
20282 * xdisp.c (display_count_lines): 3rd argument and return value now
20283 EMACS_INT. All callers changed.
20284 (pint2hrstr): Last argument is now EMACS_INT.
20286 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20287 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20288 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20289 (decode_coding_utf_16, decode_coding_emacs_mule)

20291 (decode_coding_ccl, decode_coding_charset)
20292 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.

20299 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20300 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20302 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20303 (encode_invocation_designation): Last argument P_NCHARS is now
20305 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20306 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20308 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20311 * ccl.c (Fccl_execute_on_string): Declare some variables
20314 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20316 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20318 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20320 * process.c (Fformat_network_address): Doc fix.
20322 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20324 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20326 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20328 * keyboard.c (read_char): Call Lisp function help-form-show,
20329 instead of using internal_with_output_to_temp_buffer.
20330 (Qhelp_form_show): New var.
20331 (syms_of_keyboard): Use DEFSYM macro.
20333 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20340 (list_processes_1): Delete.
20342 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20344 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20346 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20348 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20350 Fix more problems found by GCC 4.6.0's static checks.
20352 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20354 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20356 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20358 * xdisp.c (vmessage): Mark as a printf-like function.
20360 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20362 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20364 * image.c (tiff_error_handler, tiff_warning_handler): Mark as

20367 to system-supplied API.
20369 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20371 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20372 This avoids several warnings with gcc -Wstrict-overflow.
20373 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20374 directly, rather than having caller test rule sign. This avoids
20375 some unnecessary tests.
20376 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20377 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20378 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20380 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20381 (xfont_open): Avoid unnecessary tests.
20383 * composite.c (composition_gstring_put_cache): Use unsigned integer.

20392 by using the new macro.
20394 * textprop.c (set_text_properties_1): Change while to do-while,
20395 since the condition is always true at first.
20397 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20398 (interval_deletion_adjustment): Return unsigned value.
20401 * process.c (list_processes_1, create_pty, read_process_output):

20417 * print.c (print_error_message): Avoid int overflow.
20419 * font.c (font_list_entities): Redo for clarity,
20420 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20422 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20423 (font_score): Avoid potential overflow in diff calculation.
20425 * fns.c (substring_both): Remove var that is set but not used.
20426 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20428 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20430 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20431 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20432 can always succeed if overflow has undefined behavior.

20435 (wordify): Omit three unnecessary tests.
20437 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20438 All callers changed. This avoids the need for an unused var.
20440 * casefiddle.c (casify_region): Remove var that is set but not used.
20442 * dired.c (file_name_completion): Remove var that is set but not used.
20444 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20446 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20447 (Finsert_file_contents): Remove unnecessary code checking fd.
20449 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20450 Check for integer overflow on size calculations.
20452 * buffer.c (Fprevious_overlay_change): Remove var that is set
20455 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20456 Remove vars that are set but not used.
20457 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20458 (timer_check_2): Mark vars as initialized.
20460 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20462 * image.c (lookup_image): Remove var that is set but not used.
20463 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20465 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20466 that are set but not used.
20468 * xfns.c (make_invisible_cursor): Don't return garbage
20469 if XCreateBitmapFromData fails (Bug#8410).
20471 * xselect.c (x_get_local_selection, x_handle_property_notify):
20472 Remove vars that are set but not used.
20474 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20475 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20477 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20478 Remove var that is set but not used.
20479 (scroll_bar_windows_size): Now size_t, not int.
20480 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20481 Check for overflow.
20483 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20484 (map_tty_color) [!defined MSDOS]: Likewise.
20486 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20488 * coding.c: Remove vars that are set but not used.
20489 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20490 All callers changed.
20491 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20492 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20493 (decode_coding_charset): Remove vars that are set but not used.
20495 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20496 that is set but not used.
20498 * print.c (print_object): Remove var that is set but not used.
20500 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20501 The gnulib version avoids calling malloc in the usual case,
20502 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20503 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20504 * filelock.c (current_lock_owner): Likewise.
20505 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20506 * sysdep.c: Include allocator.h, careadlinkat.h.
20507 (emacs_no_realloc_allocator): New static constant.
20508 (emacs_readlink): New function.
20509 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20510 ../lib/careadlinkat.h.
20512 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20514 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20515 first non-nil return value).

20529 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20530 and thereabouts. All callers changed.
20531 (get_per_char_metric): Remove parameter `f', unused since
20532 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20534 2011-04-02 Jim Meyering <meyering@redhat.com>
20536 do not dereference NULL upon failed strdup
20537 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20538 (ns_get_family): Likewise.
20540 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20542 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20544 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20546 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20549 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20551 Add lexical binding.
20553 * window.c (Ftemp_output_buffer_show): New fun.
20554 (Fsave_window_excursion):
20555 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20557 * lread.c (lisp_file_lexically_bound_p): New function.
20558 (Fload): Bind Qlexical_binding.
20559 (readevalloop): Remove `evalfun' arg.
20560 Bind Qinternal_interpreter_environment.
20561 (Feval_buffer): Bind Qlexical_binding.
20562 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20564 (syms_of_lread): Declare `lexical-binding'.
20566 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20568 * keyboard.c (eval_dyn): New fun.
20569 (menu_item_eval_property): Use it.
20571 * image.c (parse_image_spec): Use Ffunctionp.
20573 * fns.c (concat, mapcar1): Accept byte-code-functions.
20575 * eval.c (Fsetq): Handle lexical vars.
20576 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20577 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20578 (FletX, Flet): Obey lexical binding.
20579 (Fcommandp): Handle closures.
20580 (Feval): New `lexical' arg.
20581 (eval_sub): New function extracted from Feval. Use it almost
20582 everywhere where Feval was used. Look up vars in lexical env.
20584 (Ffunctionp): Move from subr.el.
20585 (Ffuncall): Handle closures.
20586 (apply_lambda): Remove `eval_flags'.
20587 (funcall_lambda): Handle closures and new byte-code-functions.
20588 (Fspecial_variable_p): New function.
20589 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20590 but without exporting it to Lisp.
20592 * doc.c (Fdocumentation, store_function_docstring):
20593 * data.c (Finteractive_form): Handle closures.
20595 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20598 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20600 (exec_byte_code): New function extracted from Fbyte_code to handle new
20601 calling convention for byte-code-functions. Add new byte-codes.
20603 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20605 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20607 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20609 * xdisp.c (redisplay_internal): Fix prototype.
20611 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20613 * xdisp.c (SCROLL_LIMIT): New macro.
20614 (try_scrolling): Use it when setting scroll_limit.
20615 Limit scrolling to 100 screen lines.
20616 (redisplay_window): Even when falling back on "recentering",
20617 position point in the window according to scroll-conservatively,
20618 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20620 (try_scrolling): When point is above the window, allow searching
20621 as far as scroll_max, or one screenful, to compute vertical
20622 distance from PT to the scroll margin position. This prevents
20623 try_scrolling from unnecessarily failing when
20624 scroll-conservatively is set to a value slightly larger than the
20625 window height. Clean up the case of PT below the margin at bottom
20626 of window: scroll_max can no longer be INT_MAX. When aggressive
20627 scrolling is in use, don't let point enter the opposite scroll
20628 margin as result of the scroll.
20629 (syms_of_xdisp) <scroll-conservatively>: Document the
20630 threshold of 100 lines for never-recentering scrolling.
20632 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

20637 (message_log_check_duplicate): Remove parameters `prev_bol' and
20638 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20639 (redisplay_internal): Remove parameter `preserve_echo_area',
20640 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20642 * indent.c (Fvertical_motion):
20643 * window.c (window_scroll_pixel_based, Frecenter):
20644 Don't pass `need_y_p' to `move_it_by_lines'.
20646 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20648 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20649 steal a few bits to be more compact.
20650 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20651 Remove unneeded casts.
20653 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20655 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20657 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20658 binding" message (bug#7967).
20660 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20662 Fix more problems found by GCC 4.6.0's static checks.
20664 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20665 Remove unused local var.
20667 * editfns.c (Fmessage_box): Remove unused local var.
20669 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20670 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20671 Omit unused local vars.
20672 * window.c (shrink_windows): Omit unused local var.
20673 * menu.c (digest_single_submenu): Omit unused local var.
20674 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20675 Omit unused local var.
20677 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20678 Don't assume string length fits in int.
20679 (keyremap_step, read_key_sequence): Use size_t for sizes.
20680 (read_key_sequence): Don't check last_real_key_start redundantly.
20682 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20683 instead of alloca (Bug#8344).
20685 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20686 (Fbacktrace_frame): Don't assume nframes fits in int.
20688 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20690 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20693 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20695 * cm.c (calccost): Turn while-do into do-while, for clarity.
20697 * keyboard.c (syms_of_keyboard): Use the same style as later
20698 in this function when indexing through an array. This also
20699 works around GCC bug 48267.
20701 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20703 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20705 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20706 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20708 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20709 This avoids undefined behavior on integer overflow, and is a bit
20710 more convenient anyway since it is compared to a size_t variable.
20712 Variadic C functions now count arguments with size_t, not int.
20713 This avoids an unnecessary limitation on 64-bit machines, which
20714 caused (substring ...) to crash on large vectors (Bug#8344).

20724 * fns.c (concat): Likewise.
20725 * frame.c (x_set_frame_parameters): Likewise.
20726 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20727 0 if not found, not -1. All callers changed.
20729 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20730 (stack_copy_size): Now size_t, not int.
20731 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20733 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20735 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20736 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20737 All callers changed.
20739 * lisp.h (multibyte_char_to_unibyte):
20740 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20741 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20752 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20753 don't set the hook to nil, but remove the offending function instead.
20754 (Qcommand_hook_internal): Remove, unused.
20755 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20756 Vcommand_hook_internal.
20758 * eval.c (enum run_hooks_condition): Remove.
20759 (funcall_nil, funcall_not): New functions.
20760 (run_hook_with_args): Call each function through a `funcall' argument.

20774 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20775 All callers changed.
20777 * w32.c (_wsa_errlist): Use braces for struct initializers.
20779 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

20895 Remove unused variable `width'.
20897 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
20899 * w32term.c (x_set_glyph_string_clipping):
20900 Don't pass uninitialized region to CombineRgn.

20924 2011-03-23 Julien Danjou <julien@danjou.info>
20926 * term.c (Fsuspend_tty, Fresume_tty):
20927 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20928 * window.c (temp_output_buffer_show):
20929 * insdel.c (signal_before_change):
20930 * frame.c (Fhandle_switch_frame):
20931 * fileio.c (Fdo_auto_save):

20934 * cmds.c (internal_self_insert):
20935 * callint.c (Fcall_interactively):
20936 * buffer.c (Fkill_all_local_variables):
20937 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20939 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20940 unconditionally since it does the check itself.
20942 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20944 Fix more problems found by GCC 4.5.2's static checks.
20946 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20947 the first time through the loop, since we know p0 < p1 then.
20948 This also avoids a gcc -Wstrict-overflow warning.
20950 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20951 leading to a memory leak, possible in functions like
20952 load_charset_map_from_file that can allocate an unbounded number
20953 of objects (Bug#8318).
20955 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20956 that could (at least in theory) be that large.
20958 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20959 This is less likely to overflow, and avoids undefined behavior if
20960 overflow does occur. All callers changed. Use strtoul to scan
20961 for the unsigned long integer.
20962 (pint2hrstr): Simplify and tune code slightly.
20963 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
20965 * scroll.c (do_scrolling): Work around GCC bug 48228.
20966 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
20968 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
20969 This also avoids a warning with gcc -Wstrict-overflow.
20970 (validate_x_resource_name): Simplify count usage.
20971 This also avoids a warning with gcc -Wstrict-overflow.
20973 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20976 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20978 * process.c (Fmake_network_process): Use socklen_t, not int,
20979 where POSIX says socklen_t is required in portable programs.
20980 This fixes a porting bug on hosts like 64-bit HP-UX, where
20981 socklen_t is wider than int (Bug#8277).
20982 (Fmake_network_process, server_accept_connection):
20983 (wait_reading_process_output, read_process_output):
20986 * process.c: Rename or move locals to avoid shadowing.

20996 Make tparam.h and terminfo.c consistent.
20997 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20998 Include tparam.h instead, since it declares them.
20999 * cm.h (PC): Remove extern decl; tparam.h now does this.
21000 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21001 * terminfo.c: Include tparam.h, to check interfaces.
21002 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21003 (tparam): Adjust signature to match interface in tparam.h;
21004 this removes some undefined behavior. Check that outstring and len
21005 are zero, which they always are with Emacs.
21006 * tparam.h (PC, BC, UP): New extern decls.
21008 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21009 (xftfont_open): Rename locals to avoid shadowing.
21011 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21012 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21013 (OTF_TAG_SYM): Omit macro if not needed.

21021 * xml.c (make_dom): Now static.
21023 * composite.c (composition_compute_stop_pos): Rename local to
21025 (composition_reseat_it): Remove unused locals.
21026 (find_automatic_composition, composition_adjust_point): Likewise.
21027 (composition_update_it): Mark var as initialized.
21028 (find_automatic_composition): Mark vars as initialized,
21029 with a FIXME (Bug#8290).

21032 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21033 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21034 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21035 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21036 to avoid shadowing.
21038 * textprop.c (property_change_between_p): Remove; unused.
21040 * intervals.c (interval_start_pos): Now static.
21042 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

21045 Rename locals to avoid shadowing.
21047 * sound.c (wav_play, au_play, Fplay_sound_internal):
21048 Fix pointer signedness.
21049 (alsa_choose_format): Remove unused local var.
21050 (wav_play): Initialize a variable to 0, to prevent undefined
21051 behavior (Bug#8278).
21053 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21055 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21057 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21058 clobbering (Bug#8298).
21059 * sysdep.c (sys_subshell): Likewise.
21060 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21062 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21063 This should get cleaned up, so that child_setup has the
21064 same signature on all platforms.
21066 * callproc.c (call_process_cleanup): Now static.
21067 (relocate_fd): Rename locals to avoid shadowing.
21069 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21071 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21072 not to be necessary, and produces flickering.
21074 2011-03-20 Glenn Morris <rgm@gnu.org>
21076 * config.in: Remove file.
21078 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21080 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21081 are now in src/globals.h.
21082 (syms_of_minibuf): Remove spurious & from previous change.
21084 2011-03-20 Leo Liu <sdl.web@gmail.com>
21086 * minibuf.c (completing-read-function): New variable.
21087 (completing-read-default): Rename from completing-read.
21088 (completing-read): Call completing-read-function.
21090 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
21092 * xfaces.c (Fx_load_color_file):
21093 Read color file from absolute filename (bug#8250).
21095 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
21097 * makefile.w32-in: Update dependencies.
21099 2011-03-17 Eli Zaretskii <eliz@gnu.org>
21101 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

21108 (sigchld_handler): Now static.
21110 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
21111 That way, the code declares only the vars that it needs.
21112 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
21113 * s/cygwin.h (PTY_ITERATION): Likewise.
21114 * s/darwin.h (PTY_ITERATION): Likewise.

21121 (CONSTANTLIM): Remove; unused.
21122 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
21123 Define only if needed.
21125 * unexelf.c (unexec): Name an expression,
21126 to avoid gcc -Wbad-function-cast warning.
21127 Use a different way to cause a compilation error if anyone uses
21128 n rather than nn, a way that does not involve shadowing.
21129 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21131 * deps.mk (unexalpha.o): Remove; unused.
21133 New file unexec.h, the (simple) interface for unexec (Bug#8267).
21134 * unexec.h: New file.
21135 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
21136 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
21137 Depend on unexec.h.
21138 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
21139 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
21140 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
21141 Change as necessary to match prototype in unexec.h.
21143 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
21145 (back_comment, skip_chars): Mark vars as initialized.

21159 instead of using an uninitialized var.
21160 (font_sort_entities): Mark var as initialized.
21162 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
21164 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

21188 * callint.c (quotify_arg, quotify_args): Now static.
21189 (Fcall_interactively): Rename locals to avoid shadowing.
21190 Use const pointer when appropriate.

21196 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
21197 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21198 some of which prompt warnings from gcc -Wbad-function-cast.
21199 (Fformat_time_string, Fencode_time, Finsert_char):
21200 (Ftranslate_region_internal, Fformat):
21201 Rename or remove local vars to avoid shadowing.
21202 (Ftranslate_region_internal): Mark var as initialized.
21204 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
21207 * lisp.h (eassert): Check that the argument compiles, even if
21208 ENABLE_CHECKING is not defined.
21210 * data.c (Findirect_variable): Name an expression, to avoid
21211 gcc -Wbad-function-cast warning.

21223 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
21224 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
21226 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
21227 (GC_STRING_CHARS): Remove; not used.
21228 (Fmemory_limit): Cast sbrk's returned value to char *.
21230 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
21231 avoids undefined behavior in theory.
21233 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.

21236 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21237 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21238 to use the following functions instead of these macros.
21239 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21240 EMACS_INT, since callers assume the returned value fits in int.
21241 (upcase1): Likewise, for UPCASE_TABLE.
21242 (uppercasep, lowercasep, upcase): New static inline functions.
21243 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21247 Rename locals to avoid shadowing.
21248 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
21249 (regex_compile, re_search_2, re_match_2_internal):
21250 Remove unused local vars.
21251 (FREE_VAR): Rewrite so as not to use empty "else",
21252 which gcc can warn about.
21253 (regex_compile, re_match_2_internal): Mark locals as initialized.
21254 (RETALLOC_IF): Define only if needed.
21255 (WORDCHAR_P): Likewise. This one is never needed, but is used
21256 only in a comment talking about a compiler bug, so put inside
21257 the #if 0 of that comment.
21258 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21259 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21262 * search.c (boyer_moore): Rename locals to avoid shadowing.
21263 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
21264 (PREV_CHAR_BOUNDARY): Likewise.
21266 * search.c (simple_search): Remove unused var.
21268 * dired.c (compile_pattern): Move decl from here ...

21274 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
21276 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
21277 Rename locals to avoid shadowing.
21278 (Fvertical_motion): Mark locals as initialized.
21280 * casefiddle.c (casify_object, casify_region): Now static.
21281 (casify_region): Mark local as initialized.
21283 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
21285 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21286 New macros, so that the caller can use some names other than
21287 gcpro1, gcpro2, etc.
21288 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21290 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21291 argument, for consistency with GCPRO2_VAR, etc: it is now the
21292 prefix of the variable, not the variable itself. All uses
21294 * dired.c (directory_files_internal, file_name_completion):
21295 Rename locals to avoid shadowing.
21297 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21298 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21299 dired.c's scmp function, had undefined behavior.
21300 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21301 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21302 * buffer.h: ... to here, because these macros use current_buffer,
21303 and the new implementation with inline functions needs to have
21304 current_buffer in scope now, rather than later when the macros
21306 (downcase, upcase1): New static inline functions.
21307 (DOWNCASE, UPCASE1): Reimplement using these functions.
21308 This avoids undefined behavior in expressions like
21309 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21310 from race conditions in accessing the global variables
21311 case_temp1 and case_temp2.
21312 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21313 * lisp.h (case_temp1, case_temp2): Remove their decls.
21314 * character.h (ASCII_CHAR_P): Move from here ...
21315 * lisp.h: ... to here, so that the inline functions mentioned
21316 above can use them.
