* 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.

* doc/lispref/help.texi (Keys in Documentation)
* etc/NEWS:
* lisp/cus-start.el (standard):
* src/doc.c (Fsubstitute_command_keys, syms_of_doc):
Document and/or implement the new behavior instead of the old.
(syms_of_doc): New symbols 'grave' and 'straight'.
* doc/lispref/text.texi (Special Properties), etc/NEWS: Document this.
* lisp/epa.el (epa--select-keys): Remove no-longer-needed calls to
substitute-command-keys.
* src/keyboard.c (show_help_echo, parse_menu_item): Call
substitute-command-keys on the help string before displaying it.
* src/w32fns.c (globals_of_w32fns): Initialize after_deadkey to -1.
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
x_produce_glyph for newline characters. (Bug#21165)
* 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.
(w32_wnd_proc): Call deliver_wm_chars to process non-special keys
upon receiving WM_KEYDOWN or WM_SYSKEYDOWN messages. If that is
successful, don't call TranslateMessage. (Bug#19994)
* src/w32fns.c (Fw32_shell_execute): Don't use filename_to_utf16
and filename_to_ansi to convert the DOCUMENT argument, as it could
be a URL that is not limited to MAX_PATH characters. Instead, use
MultiByteToWideChar directly, and allocate heap storage as
required to accommodate the converted string. Likewise with
non-Unicode operation. Ensure OPERATION is null-terminated, even
if it is longer than 32K bytes. (Bug#21158)
* src/xdisp.c (expose_window, expose_area): Avoid comparisons
between signed negative values and unsigned values. This
prevented redisplay on expose events when the window showed a very
large image.
* src/w32proc.c (Fw32_get_codepage_charset): Avoid compilation
warning.
(CompareStringW_Proc): New typedef.
(w32_compare_strings): Use it, to pacify compiler warnings under
"-Wincompatible-pointer-types".
* src/w32fns.c (GetDiskFreeSpaceExW_Proc)
(GetDiskFreeSpaceExA_Proc): New typedefs.
(Ffile_system_info): Use them, to pacify compiler warnings under
"-Wincompatible-pointer-types".
Copyright-paperwork-exempt: yes
Use slightly-longer cost vectors. Without this change,
calculate_direct_scrolling can have a subscript violation when
FRAME_LINES (frame) <= delta.
* src/scroll.c (calculate_scrolling, calculate_direct_scrolling)
(line_ins_del, do_line_insertion_deletion_costs):
Allocate and use slightly-larger cost vectors, ones based on
FRAME_TOTAL_LINES instead of FRAME_LINES.
* src/coding.c (encode_coding_object): Also initialize
coding->src_pos and coding->src_pos_byte when NILP (src_object).
This avoids later use of uninitialized storage.
This simplifies time conversions in other time zones.
It also prevents display-time-world tampering with TZ (Bug#21020).
* admin/admin.el (add-release-logs):
Use improved add-log-time-format API.
* admin/merge-gnulib (GNULIB_MODULES): Add time_rz, timegm.
(GNULIB_TOOL_FLAGS): Avoid flexmember, setenv, unsetenv.
* configure.ac (tzalloc): Remove test for this, since
Emacs no longer uses HAVE_TZALLOC directly.

(tzeqlen): New constant; prefer it to (sizeof "TZ=" - 1).
(emacs_localtime_rz, emacs_mktime_z, xtzalloc, xtzfree)
(tzlookup): New static functions.
(init_editfns): New arg DUMPING. All uses changed.
(init_editfns): Omit most initialization if dumping, not if
!initialized. Initialize wall_clock_tz and local_tz.
(emacs_nmemftime, format_time_string): Time zone argument can now
be any time zone, not just a boolean for UTC or local time. All
callers changed.
(Fformat_time_string, Fencode_time, Fcurrent_time_string)

(Fdecode_time, Fset_time_zone_rule): ZONE arg can now also take
the same form as with the other new additions.

Remove; now supplied by gnulib.
* src/emacs.c (main):
* src/lisp.h (init_editfns): Adjust to init_editfns API change.

Remove code that tried to handle a subset of these situations by
manual iteration of buffer text. (Bug#17777)
Crowe's patch in:
https://lists.gnu.org/archive/html/emacs-devel/2015-07/msg00106.html
A problem in this area has been reported by several users; see
Bug#16737, Bug#17101, Bug#17026, Bug#17172, Bug#19320, Bug#20283.
This fix differs from Mike Crowe's patch in that it should avoid a
race condition that could lose SIGIO signals. ignore_sigio dates
back to the 1980s when some platforms couldn't block signals, and
could only ignore them, which led to races when signals arrived
while being ignored. We shouldn't have to worry about those old
platforms now.
* src/dispextern.h, src/sysdep.c (ignore_sigio): Remove.
* src/emacs.c (shut_down_emacs):
Don't call ignore_sigio; unrequest_sigio should suffice.
* src/keyboard.c (kbd_buffer_store_buffered_event):
Use unrequest_sigio, not ignore_sigio.
(kbd_buffer_get_event):
Call request_sigio when getting the ball rolling again.
Improve the heuristic for distinguishing stack overflows from
other SIGSEGV causes (Bug#21004). Corinna Vinschen explained that
the getrlimit method wasn't portable to Cygwin; see:
https://www.cygwin.com/ml/cygwin/2015-07/msg00092.html
Corinna suggested pthread_getattr_np but this also has problems.
Instead, replace the low-level system stuff with a simple
heuristic based on known good stack addresses.
* src/eval.c, src/lisp.h (near_C_stack_top): New function.
* src/sysdep.c: Don't include <sys/resource.h>.
(stack_direction): Remove. All uses removed.
(stack_overflow): New function.
(handle_sigsegv): Use it instead of incorrect getrlimit heuristic.
Make SEGV fatal in non-main threads.
After stack overflow, command_loop calls init_eval, and this needs to
clear gcprolist and byte_stack_list (Bug#20996).
* src/alloc.c (init_alloc):
Move gcprolist and byte_stack_list initialization from here ...
* src/eval.c (init_eval): ... to here.
* src/macfont.m (macfont_family_cache): New variable.
(syms_of_macfont): Initialize it.
(macfont_available_families_cache): New variable.
(macfont_invalidate_family_cache, macfont_get_family_cache_if_present)
(macfont_set_family_cache, macfont_invalidate_available_families_cache)
(macfont_handle_font_change_notification)
(macfont_init_font_change_handler)
(macfont_copy_available_families_cache): New functions.
(macfont_create_family_with_symbol): Use font family caches.
(macfont_list, macfont_list_family): Use
macfont_copy_available_families_cache instead of
mac_font_create_available_families.
