* src/alloc.c (mark_object): Fix bug in checking code.
When GC_CHECK_MARKED_OBJECTS is defined, the bug caused
CHECK_ALLOCATED_AND_LIVE_SYMBOL to repeatedly do the
CHECK_ALLOCATED and CHECK_LIVE tests for the first symbol in each
bucket. The bug did not affect behavior either in the normal case
where GC_CHECK_MARKED_OBJECTS is not defined, or where Emacs does
not have an internal error that a properly-written
CHECK_ALLOCATED_AND_LIVE_SYMBOL would detect.
* src/bidi.c (bidi_resolve_neutral): Treat all Bn (a.k.a. "control")
characters the same as directional formatting controls.
(bidi_level_of_next_char): Include all Bn characters in rule L1,
as mandated by the UBA.
* src/xdisp.c (redisplay_internal, try_cursor_movement)
(try_window_reusing_current_matrix, try_window_id): Remove
redundant restrictions on redisplay optimizations based on the
frame's 'redisplay' flag. See
http://osdir.com/ml/general/2015-10/msg02110.html for the relevant
discussions.
* src/coding.c (choose_write_coding_system): More validation of
coding-system from various sources. Suggested by Andreas Schwab
<schwab@linux-m68k.org>. (Bug#21602)
* src/fileio.c (choose_write_coding_system)
(Finsert_file_contents): Check validity of coding-system-for-write
and coding-system-for-read bound by the caller. (Bug#21602)
Revert "Improve last commit to process.c" and "Remove callback-handled
channels from Available set" because they did not fix bug#21313.
This reverts commits bfa1aa8e2b and
27f871907cc24f33a7d12ac3a4ab71a88f0bc554..
* src/xdisp.c (try_window_id, try_window_reusing_current_matrix)
(try_cursor_movement): Don't relax requirements for redisplay
optimizations for the selected frame. (Bug#21597)
This reverts commit c4c1fb9772.
* src/xdisp.c (try_window_id, try_window_reusing_current_matrix)
(try_cursor_movement): Relax requirements for redisplay
optimizations for the selected frame. (Bug#21597)
These optimizations were previously disabled by the
windows_or_buffers_changed flag, which now is not set
when only some frames need to be redrawn.
* src/xdisp.c (redisplay_internal): Redisplay any frame whose
'redisplay' flag is set.
(try_window_reusing_current_matrix, try_window_id)
(try_cursor_movement): Disable these optimizations when the
frame's 'redisplay' flag is set.
* src/xfns.c (x_set_menu_bar_lines, x_change_tool_bar_height):
* src/xfaces.c (Finternal_make_lisp_face, Finternal_copy_lisp_face)
(Finternal_set_lisp_face_attribute, update_face_from_frame_parameter):
* src/frame.c (x_set_screen_gamma): Set the specific frame's
`redisplay' bit rather than windows_or_buffers_changed.
* src/window.c (apply_window_adjustment): Remove redundant setting of
windows_or_buffers_changed.
* src/xdisp.c (redisplay_internal): Set the specific frame's
`redisplay' bit rather than update_mode_lines in response to
cursor_type_changed.
(syms_of_xdisp): Use hash-tables for redisplay_*_cause tables.
(AINC): Adjust accordingly.
* src/window.c (Fpos_visible_in_window_p): Clarify the meaning of
t for POS. See
http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg01040.html
for the original report.
* doc/lispref/windows.texi (Window Start and End): Clarify the
meaning of t for the POSITION argument of pos-visible-in-window-p.
* src/xdisp.c (redisplay_internal): Inhibit freeing of realized
faces for as long as we might have desired matrices that reference
those faces. (Bug#21428)
* src/frame.h (struct f): New flag face_change.
* src/xfaces.c (Finternal_make_lisp_face)
(Finternal_copy_lisp_face, Finternal_set_lisp_face_attribute)
(update_face_from_frame_parameter): Set the face_change flag only
for the frame whose faces are affected.
* src/xdisp.c (init_iterator): If a frame's face_change flag is
set, free faces only on that frame.
(redisplay_internal): Disable "display optimization 1" if the
frame's face_change flag is set.
(redisplay_window): Don't allow skipping a window's redisplay if
its frame's face_change flag is set.
* src/frame.c (x_set_screen_gamma): Instead of calling
Fclear_face_cache, call clear_face_cache and set
windows_or_buffers_changed to a non-zero value. This avoids
setting the global face_change flag that triggers face realization
on all frames and thorough redisplay of all of them.
* lisp/term/tty-colors.el (tty-register-default-colors): Don't
clear face cache if the selected frame is a GUI frame.
* src/nsterm.m:
* src/lisp.h:
* src/editfns.c:
* src/doprnt.c: Add 'coding' cookies -- these files include
Unicode characters and should be decoded as UTF-8.
* src/xdisp.c (produce_stretch_glyph): Support ':relative-width'
space display spec on text-mode terminals, by calling
PRODUCE_GLYPHS instead of x_produce_glyphs. Remove the HAVE_WINDOW_SYSTEM
guards from the supporting code, as well as the test for a GUI frame.
* lisp/filenotify.el (file-notify-callback): Fix typo.
(gfile-valid-p): Remove defalias.
* src/gfilenotify.c (dir_monitor_callback): Cancel the monitor if
the file or directory to be watched is deleted.
(Fgfile_add_watch): Make watch_object a triple.
(Fgfile_rm_watch): Check, whether watch is cancelled already.
(Fgfile_valid_p): New defun.
(syms_of_gfilenotify): Declare Sgfile_valid_p.
* src/xdisp.c (face_before_or_after_it_pos): Use do-while rather
than while loop to avoid GCC -Wmaybe-uninitialized diagnostic with
charpos. The loop should always execute at least once anyway.
