* 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-test03-autorevert)
(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.
* src/w32notify.c (report_w32notify_error): New function.
(Fw32notify_add_watch, Fw32notify_rm_watch): Use it to report
errors, instead of calling report_file_error. (Bug#21432)
Problem reported by Ashish SHUKLA in:
http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00531.html
* configure.ac: Check for struct unipair.unicode instead of for
<linux/kd.h>, since that’s more specific to what the code actually needs.
* src/terminal.c: Use HAVE_STRUCT_UNIPAIR_UNICODE, not HAVE_LINUX_KD_H.
* src/indent.c (Fvertical_motion): Don't leave point in the middle
of an overlay string with newlines, as that will position the
cursor after the string at whatever column is there. (Bug#21468)
* lisp/emacs-lisp/syntax.el (syntax-propertize--done): Remove.
(syntax-propertize): Set syntax-propertize--done even if
syntax-propertize-function is nil. Avoid recursive invocations.
(syntax-propertize-chunks): New var.
(internal--syntax-propertize): Use it. Rename from syntax--jit-propertize.
Simplify.
(parse-sexp-propertize-function): Don't set any more.
* src/syntax.c (SETUP_SYNTAX_TABLE): Call parse_sexp_propertize as needed.
(parse_sexp_propertize): Don't assume charpos is not yet propertized.
Call Qinternal__syntax_propertize instead of
Vparse_sexp_propertize_function. Truncate e_property if needed.
(update_syntax_table_forward): Streamline.
(syms_of_syntax): Define Qinternal__syntax_propertize.
(syntax_propertize__done): Rename from parse_sexp_propertize_done.
Mostly this just changes ` to ' in static text. Some exceptions:
* INSTALL.REPO: Use curved quotes, as the diagnostic in question
typically does that now.
* admin/quick-install-emacs (TRY, top level):
Use straight quoting in diagnostics.
* src/README: Fix working-directory confusion.
* lisp/emacs-lisp/syntax.el (syntax--jit-propertize): New function.
(parse-sexp-propertize-function): Use it.
(syntax-propertize): Disable parse-sexp-propertize-function.
* src/syntax.c (parse_sexp_propertize, update_syntax_table_forward):
New functions.
(syms_of_syntax): New vars `parse-sexp-propertize-done' and
`parse-sexp-propertize-function'.
* src/syntax.h (struct gl_state_s): Add `e_property_truncated' field.
(UPDATE_SYNTAX_TABLE_FORWARD): Use update_syntax_table_forward.
(SETUP_BUFFER_SYNTAX_TABLE): Set e_property_truncated.
* lisp/progmodes/elisp-mode.el (elisp-byte-code-syntax-propertize):
Don't assume `point' is set.
The function is used now even in non-graphical environments.
Problem reported by Glenn Morris in:

* src/font.c (Finternal_char_font): Move here ...
* src/fontset.c (Finternal_char_font): ... from here.
This should help Emacs work better out-of-the-box on Linux consoles,
which have only limited support for displaying Unicode characters.
Also, undo the recent change that caused text-quoting-style to
affect quote display on terminals, so that the two features are
independent. See Alan Mackenzie in:
http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00244.html
Finally, add a style parameter to startup--setup-quote-display,
so that this function can also be invoked after startup, with
different styles depending on user preference at the time.
* configure.ac: Check for linux/kd.h header.
* doc/emacs/display.texi (Text Display): Document quote display.
* doc/lispref/display.texi (Active Display Table):
* etc/NEWS:
* lisp/startup.el (startup--setup-quote-display, command-line):
text-quoting-style no longer affects quote display.
* doc/lispref/frames.texi (Terminal Parameters): Fix typo.
* lisp/international/mule-util.el (char-displayable-p):
* lisp/startup.el (startup--setup-quote-display):
On a text terminal supporting glyph codes, use the reported
glyph codes instead of the terminal coding system, as this
is more accurate on the Linux console.
* lisp/startup.el (startup--setup-quote-display):
New optional arg STYLE.
* src/fontset.c (Finternal_char_font):
Report glyph codes for a text terminal, if they are available.
Currently this is supported only for the Linux console.
* src/termhooks.h (struct terminal): New member glyph-code-table.
* src/terminal.c [HAVE_LINUX_KD_H]: Include <errno.h>, <linux/kd.h>.
(calculate_glyph_code_table) [HAVE_LINUX_KD_H]: New function.
(terminal_glyph_code): New function.
* src/dispnew.c (redraw_frame): Don't redisplay all frames.
* src/xdisp.c (echo_area_display): Set the frame's `redisplay' bit
rather than returning a "resized_p" boolean.
(redisplay_internal): Adjust call accordingly.
* src/xfaces.c (free_realized_faces): Don't redisplay all frames.
(free_all_realized_faces): Set windows_or_buffers_changed so as to ease
tracking of this undesirable situation.
* src/w32.c (sys_unlink): If 'unlink' fails, and the argument is a
symlink to a directory, try again with 'rmdir'.
(is_symlink): If the argument is a symlink to a directory, set a
bit in the return value to indicate that fact.
* src/process.c (wait_reading_process_output): Add a
'tls_available' set and manipulate it instead of 'Available' when
checking TLS inputs. Assign the value to 'Available' only if we
find any TLS data waiting to be read. This avoids error messages
from 'inotify' that tries to read data it shouldn't. (Bug#21337)
* src/xdisp.c (forget_escape_and_glyphless_faces): New function.
(display_echo_area_1, redisplay_internal): Call it to avoid
reusing stale face IDs for 'escape-glyph' and 'glyphless-char'
faces, which could case a segfault if the frame's face cache was
freed since the last redisplay. (Bug#21394)
* src/xfaces.c (free_realized_faces): Call forget_escape_and_glyphless_faces.
* src/dispextern.h (forget_escape_and_glyphless_faces): Add prototype.
