* src/w32uniscribe.c (uniscribe_otf_capability): Add commentary
about the expected results and why the new Uniscribe APIs are not
used in this function.
(ScriptGetFontScriptTags_Proc, ScriptGetFontLanguageTags_Proc)
(ScriptGetFontFeatureTags_Proc): New function typedefs.
(uniscribe_new_apis): New static variable.
(uniscribe_check_features): New function, implements OTF features
verification while correctly accounting for features in the list
after the nil member, if any.
(uniscribe_check_otf_1): New function, retrieves the features
supported by the font for the requested script and language using
the Uniscribe APIs available from Windows Vista onwards.
(uniscribe_check_otf): If the new Uniscribe APIs are available,
use them in preference to reading the font data directly. Call
uniscribe_check_features to verify that the requested features are
supported, replacing the original incomplete code.
(syms_of_w32uniscribe): Initialize function pointers for the new
Uniscribe APIs. (Bug#21260)
(otf_features): Scan the script, langsys, and feature arrays back
to front, so that the result we return has them in alphabetical
order, like ftfont.c does.
* src/w32fns.c (syms_of_w32fns) <w32-disable-new-uniscribe-apis>:
New variable for debugging w32uniscribe.c code.
* src/window.c (Fwindow_edges, Fwindow_pixel_edges)
(Fwindow_absolute_pixel_edges, Fwindow_inside_edges)
(Fwindow_inside_pixel_edges, Fwindow_inside_absolute_pixel_edges):
Move to window.el.
(calc_absolute_offset): Remove.
* lisp/frame.el (frame-edges): New function.
* lisp/window.el (window-edges, window-pixel-edges)
(window-absolute-pixel-edges): Move here from window.c.
(window-body-edges, window-body-pixel-edges)
(window-absolute-body-pixel-edges): Move here from window.c and
rename "inside" to "body". Keep old names as aliases.
(window-absolute-pixel-position): New function.
* src/w32fns.c (TITLEBAR_INFO): Make it a typedef so MinGW64
builds can use the declaration from the system headers.
(GetTitleBarInfo_Proc, Fx_frame_geometry): Adapt to new
definition of TITLEBAR_INFO.
Suggested by Eli Zaretskii <eliz@gnu.org>
* src/image.c (image_size_error): New function. All uses of
image_error with "Invalid image size ..." changed to use it.
* src/image.c (image_size_error, xbm_load_image, xbm_load)
(xpm_load, xpm_load_image, xpm_load, pbm_load, png_load_body)
(jpeg_load_body, tiff_load, gif_load, imagemagick_load_image)
(imagemagick_load, svg_load, svg_load_image, gs_load)
(x_kill_gs_process):
* src/lread.c (load_warn_old_style_backquotes):
* src/xfaces.c (load_pixmap):
* src/xselect.c (x_clipboard_manager_error_1):
Use %qs, not uLSQM and uRSQM.
* src/syntax.c (Finternal_describe_syntax_value):
Prefer Fsubstitute_command_keys to Fformat, as this lets
us use AUTO_STRING.
* src/xdisp.c (vadd_to_log): Use AUTO_STRING on the format argument,
as it's now guaranteed to be ASCII.
* src/xselect.c (x_clipboard_manager_error_2):
Avoid grave accent in low-level stderr diagnostic.
* src/print.c (print_error_message):
Don't assume that the caller's name is unibyte.
* src/xdisp.c (vadd_to_log):
Don't assume that the formatted diagnostic is unibyte.
Also, close some minor races when opening image files, by opening
them once instead of multiple times.
* src/gtkutil.c (xg_get_image_for_pixmap):
* src/image.c (xpm_load, tiff_load, gif_load, imagemagick_load)
(svg_load):
* src/nsimage.m (allocInitFromFile:):
* src/xfns.c (xg_set_icon):
Encode file name, since x_find_image_file no longer does that.
* src/image.c (x_find_image_fd): New function.
(x_find_image_file): Use it. Do not encode resulting file name,
since callers sometimes need it decoded.
(slurp_file): File arg is now a fd, not a file name.
All callers changed. This saves us having to open the file twice.
(xbm_load, xpm_load, pbm_load, png_load_body, jpeg_load_body)
(svg_load):
Use x_find_image_fd and fdopen to save a file-open.
Report file name that failed.
* src/lread.c (openp): If PREDICATE is t, open the file in binary mode.
Problem reported by Ernesto Alfonso (Bug#21279).
* doc/lispref/searching.texi (Regexp Search, Simple Match Data):
Document more carefully what happens to match data after a failed
search.
* src/search.c (Fmatch_beginning, Fmatch_end): Document that
the return value is undefined if the last search failed.
(Fmatch_data): Simplify doc string line 1.
When run with --batch, check that curved quotes are compatible with
the system locale before outputting them in diagnostics.
Problem reported by Eli Zaretskii in:
http://lists.gnu.org/archive/html/emacs-devel/2015-08/msg00594.html
* lisp/startup.el (command-line): Set internal--text-quoting-flag
after the standard display table is initialized.
* src/doc.c (default_to_grave_quoting_style): New function.
(text_quoting_style): Use it.
(text_quoting_flag): New static var, visible to Lisp as
internal--text-quoting-flag.
* src/emacs.c: Include <wchar.h> if available.
(using_utf8): New function.
(main): Use it to initialize text_quoting_flag.
* src/regex.h (btowc) [WIDE_CHAR_SUPPORT && emacs]:
Don't define, as it's not needed and it clashes with wchar.h.
* nt/configure.bat: Remove everything except the blurb about the
new build procedure.
* make-dist: Remove references to makefile.w32-in in various
directories, and to files in nt/ that were deleted.
* etc/NEWS: Mention the fact that the files were dropped.
* src/doprnt.c (doprnt):
Format ` and ' as per ‘text-quoting-style’.
* src/xdisp.c (vmessage, message): Mention that the format should
not contain ` or '.
This is a followup to the recent doc string change, and deals with
diagnostics and the like. This patch is more conservative than
the doc string change, in that the behavior of ‘format’ changes
only if its first arg contains curved quotes and the user prefers
straight or grave quotes. (Come to think of it, perhaps we should
be similarly conservative with doc strings too, but that can wait.)
The upside of this conservatism is that existing usage is almost
surely unaffected. The downside is that we'll eventually have to
change Emacs's format strings to use curved quotes in places where
the user might want curved quotes, but that's a simple and
mechanical translation that I'm willing to do later. (Bug#21222)
* doc/lispref/help.texi (Keys in Documentation):
Move description of text-quoting-style from here ...
* doc/lispref/strings.texi (Formatting Strings):
... to here, and describe new behavior of ‘format’.
* etc/NEWS: Describe new behavior.
* lisp/calc/calc-help.el (calc-describe-thing):
* lisp/emacs-lisp/derived.el (derived-mode-make-docstring):
* lisp/info.el (Info-find-index-name):
Use ‘concat’ rather than ‘format’ to avoid misinterpretation
of recently-added curved quotes.
* src/doc.c (uLSQM0, uLSQM1, uLSQM2, uRSQM0, uRSQM1, uRSQM2):
Move from here ...
* src/lisp.h: ... to here.
* src/doc.c (text_quoting_style): New function.
(Fsubstitute_command_keys): Use it.
* src/editfns.c (Fformat): Implement new behavior.
* src/lisp.h (enum text_quoting_style): New enum.
* src/alloc.c (purecopy): Warn about removing a string's text
properties even when the same string was already pure-copied
earlier.
* lisp/progmodes/elisp-mode.el (elisp--xref-format)
(elisp--xref-format-extra): Fix the commentary.
* src/alloc.c (run_finalizer_handler):
* src/charset.c (load_charset_map_from_vector):
* src/nsimage.m (ns_load_image):
* src/xfaces.c (load_pixmap, load_color2):
Simplify, now that add_to_log has a variable number of args.
* src/image.c (image_error): Take a variable number of args.
Callers simplified.
* src/lisp.h (add_to_log, vadd_to_log): Adjust to new APIs.
* src/xdisp.c (format_nargs, vadd_to_log): New functions.
(add_to_log): Make varargs, and reimplement in terms of vadd_to_log.
* src/xfaces.c (merge_face_ref): Fix typo that omitted color name.
* keyboard.c (apply_modifiers_uncached, parse_solitary_modifier)
(parse_modifiers_uncached): React gracefully to "up-" modifiers:
those may easily be injected by user-level Lisp code.
(read_key_sequence): Discard unbound up-events like unbound
down-events: they are even more likely only relevant for special
purposes.
While Emacs will not produce up-events on its own currently (those are
converted to drag or click events before being converted to
Lisp-readable structures), the input queue can be made to contain them
by synthesizing events to `unread-command-events'. Emacs should deal
consistently with such events.
* src/xdisp.c (append_space_for_newline): Don't try to fix ascent
and descent values of non-empty glyph rows, since they could have
forced low values deliberately. (Bug#21243)
* src/emacs.c (synchronize_locale) [WINDOWSNT]: Call fixup_locale
after setting LC_ALL to the desired locale, to avoid affecting how
numbers are read and printed. (Bug#21223)
* src/xsettings.c (parse_settings): Don't use Xft/DPI default
value of -1, which evaluates to 2**32 - 1 (Bug#21152).
Remove unnecessary cast while we're in the neighborhood.
* src/dispnew.c (add_window_display_history) [GLYPH_DEBUG]:
Remove redundant quotes.
* src/doc.c (uLSQM, uRSQM): New macros.
* src/doc.c (Fsubstitute_command_keys):
* src/syntax.c (Finternal_describe_syntax_value): Follow the user
preference for quotes rather than hardcoding the ‘grave’ style.
* src/regex.c (PUSH_FAILURE_POINT, POP_FAILURE_POINT)
(re_match_2_internal) [DEBUG]: In debugging output, quote C
strings with "...", not `...'.
* src/xdisp.c (pop_it): Reset the flag to ignore overlays at this
buffer position, if we move the iterator to a new position as
result of jumping over text covered by a "replacing" display
property.
* test/redisplay-testsuite.el (test-redisplay-4): Add 2 new tests.
* src/w32fns.c (w32_reset_stack_overflow_guard)
(stack_overflow_handler): New functions for handling C stack
overflow exceptions.
(my_exception_handler): Handle EXCEPTION_STACK_OVERFLOW exceptions
specially, and zero out except_addr if we do.
(globals_of_w32fns): Initialize dwMainThreadId in non-interactive
mode.
* src/sysdep.c [HAVE_STACK_OVERFLOW_HANDLING]: Add !WINDOWSNT to
the condition, as HAVE_STACK_OVERFLOW_HANDLING is now defined for
the MinGW build, but the code guarded by that is for Posix hosts.
* src/keyboard.c (command_loop) [WINDOWSNT]: Call
w32_reset_stack_overflow_guard.
* nt/inc/ms-w32.h (sigjmp_buf): New typedef.
(sigsetjmp): New macro.
(w32_reset_stack_overflow_guard): Declare the prototype.
* configure.ac (HAVE_STACK_OVERFLOW_HANDLING): Set to 1 for MinGW.
* src/xdisp.c (handle_invisible_prop): If the next change of
invisibility spec does not mean the beginning of a visible text,
update the string position from which to start the search for the
next invisibility change. This avoids an infinite loop when we
have more than one invisibility spec that are made inactive by
buffer-invisibility-spec. Simplify code. (Bug#21200)
* test/redisplay-testsuite.el (test-redisplay-4): Add a test case
for the situation that caused bug #21200.
Rename help-quote-translation to text-quoting-style,
and use symbols rather than characters as values.

This is needed to correctly handle the session's first keystroke,
if it has any modifiers. (Bug#19994)
* src/xdisp.c (append_space_for_newline): Honor 'line-height'
property and 'line-spacing' frame parameter or variable or
property for empty lines, by doing the same processing as in

* src/profiler.c (make_log): Make args EMACS_INT, not int,
to avoid unwanted behavior on 'int' overflow.
(make_log, evict_lower_half, record_backtrace):
Use ptrdiff_t, not int, for object indexes.
* src/w32fns.c (syms_of_w32fns) <w32-use-fallback-wm-chars-method>:
New variable.
(w32_wnd_proc): Use it to invoke the old code that processed
character keys, as fallback, when this variable is non-nil. Fix
typos in comments. (Bug#19994)
* src/w32fns.c (get_wm_chars, deliver_wm_chars): New functions.
(FPRINTF_WM_CHARS) [DEBUG_WM_CHARS]: New macro for debugging.

upon receiving WM_KEYDOWN or WM_SYSKEYDOWN messages. If that is
successful, don't call TranslateMessage. (Bug#19994)
