* 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
27f871907c..
* 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.
Although \( is needed in docstrings in Elisp code, it is not needed in
docstrings in C code, since C function definitiions do not start with
a parenthesis. The backslashes made the docstrings a bit harder to
read and to format in columns. Also, some C docstrings had ( in
column 1 and this did not appear to be causing any problems. So,
simplify C docstrings by replacing \( with ( and \) with ).
Make --enable-gcc-warnings a bit pickier, by also using -Wswitch.
* configure.ac (WERROR_CFLAGS): Don’t add -Wno-switch.
* lib-src/etags.c (main, consider_token, C_entries):
* src/coding.c (encode_invocation_designation):
* src/data.c (Ftype_of):
* src/eval.c (Fdefvaralias, default_toplevel_binding)
(Fbacktrace__locals, mark_specpdl):
* src/lisp.h (record_xmalloc):
* src/syntax.c (scan_lists, scan_sexps_forward):
* src/window.c (window_relative_x_coord):
* src/xdisp.c (push_it, pop_it):
* src/xterm.c (xg_scroll_callback, x_check_fullscreen):
Error out or do nothing (as appropriate) if a switch statement
with an enum value does not cover all of the enum.
* src/dispextern.h (struct iterator_stack_entry.u.comp):
Remove unused member discovered by using -Wswitch.
* src/lisp.h (record_xmalloc): Add a ‘+ 0’ to pacify -Wswitch.
* src/vm-limit.c (check_memory_limits):
Simplify warning-diagnostic computation by using a table.
* src/inotify.c (report_inotify_error): New function. Clone of
report_w32notify_error.
(inotify_callback, symbol_to_inotifymask, Finotify_add_watch)
(Finotify_rm_watch): Use it.
* lisp/filenotify.el (file-notify-rm-watch): Ignore `file-notify-error'.
* src/inotify.c (Finotify_valid_p): Adapt docstring.
* test/automated/file-notify-tests.el ()

(file-notify-test04-file-validity)
(file-notify-test04-file-validity-remote)
(file-notify-test05-dir-validity)
(file-notify-test05-dir-validity-remote): Adapt docstring.
(file-notify-test04-file-validity): Let events arrive before
calling final `file-notify-valid-p'. Do not ignore errors.
(file-notify-test05-dir-validity): Do not manipulate
`temporary-file-directory', it isn't necessary. Let events arrive
before calling final `file-notify-valid-p'. Do not ignore errors.
