new variable.

a buffer trying to be non-destructive, by using replace-buffer-contents.
(revert-buffer-insert-file-contents-delicately): New function, alternative
to revert-buffer-insert-file-contents-function--default-function.
(revert-buffer-with-fine-grain-max-seconds): New variable. Passed as
argument MAX-SECS of replace-buffer-contents.

(cperl-set-style): Add indentation style recommended by Damian Conway's
book "Perl Best Practices".
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-mode-test-indent-styles): Add a test to verify indentation
and unraveling of conditionals (bug#43457).
Add a command 'lossage-size' to set the maximum
number or recorded keystrokes (Bug#38796).
* src/keyboard.c (lossage_limit):
Static variable with the current lossage size limit.
(MIN_NUM_RECENT_KEYS): Renamed from NUM_RECENT_KEYS.
Set it as 100 and use it as the minimum value for lossage_limit.
Keep the same default for the vector size as before (300).
(lossage-size): New command.
(update_recent_keys): Helper function.
(command_loop_1)
(record_char)

the test also in batch mode.
For some values outside integers 0≤k≤n, (n choose k) gave wrong
results, entered infinite recursion or used unreasonably amounts of
stack space. This change fixes that and extends the function to all
integer arguments using the definitions from M. J. Kronenburg
(https://arxiv.org/abs/1105.3689).
* lisp/calc/calc-comb.el (calcFunc-choose):
Fix sign error to prevent infinite recursion and extend function to
handle all integer arguments.
(math-choose-iter, math-choose-float-iter): Rewrite in iterative form;
no TCO in elisp yet.
* test/lisp/calc/calc-tests.el (calc-tests--fac, calc-tests--choose)

interactive form.

functions.
(initialize_environment): Use them.

functions.

(tramp-archive-test-file-archive-hexlified): New defun.
(tramp-archive-test02-file-name-dissect): Use it. (Bug#43353)
* test/Makefile.in (TEST_LOCALE): Remove.
(emacs): Don't force LC_ALL=C, since it causes problems with
non-ascii directories. This mirrors a 7-year old lisp/Makefile change.
* test/lisp/subr-tests.el (subr-test-version-parsing):
* test/lisp/emacs-lisp/gv-tests.el (gv-dont-define-expander-other-file):
* test/src/callint-tests.el (call-interactively/incomplete-multibyte-sequence):
* test/src/emacs-module-tests.el (module/describe-function-1):
Don't fail if curly quotes are in use, as they can be if LC_ALL != C.

* lisp/net/dbus.el (dbus-compound-types): New defconst.
(dbus): New defgroup.
(dbus-show-dbus-errors): New defcustom.
(dbus-ignore-errors): Use it.
(dbus-set-property): Simplify.
(dbus-property-handler): Implement other compound types of properties.
* test/lisp/net/dbus-tests.el (dbus--test-register-service)
(dbus-test05-register-property): Extend tests.
It is necessary to make plist-get as a generalized variable, and this
definition allows user to use setf and other useful functions on
plist-get.
* lisp/emacs-lisp/gv.el: Add gv-define-expander for plist-get
* lisp/emacs-lisp/gv-tests.el: Add new tests for plist-get
Enabling mouse-wheel-mode binds two different mouse events, depending
on the operating system. The correct way to check for those events is
by checking mouse-wheel-up-event, as explained in the ELisp manual.
* test/lisp/mwheel-tests.el (mwheel-test-enable/disable): Check
mouse-wheel-up-event instead of mouse-4 to make the test work
irrespective of the platform it's running.
* doc/misc/dbus.texi (Properties and Annotations)
(Receiving Method Call): Document optional type symbol in
`dbus-set-property' and `dbus-register-property'.
* lisp/net/dbus.el (dbus-error-unknown-interface)
(dbus-error-unknown-method, dbus-error-unknown-object)
(dbus-error-unknown-property): New defconsts.
(dbus-peer-handler): Improve error handling.
(dbus-introspect-get-signature): Handle also properties.
(dbus-set-property, dbus-register-property): Allow optional TYPE
symbol for VALUE. (Bug#43252)
(dbus-property-handler): Implement property types. Improve error
handling.
* src/dbusbind.c (dbus-message-internal, dbus-registered-objects-table):
Fix docstring.
* test/lisp/net/dbus-tests.el (dbus-test05-register-property):
Extend test.
(dbus-test05-register-property-several-paths): New test.
* test/lisp/custom-tests.el (custom--test-theme-variables): "make
check" in the main directory didn't work because the path was
wrong. Use EMACS_TEST_DIRECTORY to find the test directory
instead.
* lisp/net/dbus.el (dbus-get-property): Adapt docstring.
(dbus-set-property): Handle case of `:write' access type.
(dbus-get-other-registered-properties): Rename from
`dbus-get-other-registered-property'.
(dbus-property-handler): Fix thinkos.
* src/dbusbind.c (xd_read_message_1): Add error_name to event args
in case of DBUS_MESSAGE_TYPE_ERROR.
* test/lisp/net/dbus-tests.el (dbus--test-enabled-session-bus)
(dbus--test-enabled-system-bus): Make them defconst.
(dbus--test-service, dbus--test-path, dbus--test-interface):
New defconst. Replace all occurences of `dbus-service-emacs' by
`dbus--test-service'.
(dbus--test-method-handler): New defun.
(dbus-test04-register-method, dbus-test05-register-property): New tests.
* lisp/custom.el (enable-theme): Since we are enabling the theme, bind
custom--inhibit-theme-enable to nil. Then rely on custom-push-theme
to do the right thing with the theme settings and prior user settings,
instead of manipulating the property here. This way, when disabling a
theme, we restore user preferences, even when the values were changed
outside of customize.
(disable-theme): Call custom-push-theme instead of handling theme
settings directly.
(custom-push-theme): Avoid another instance of Bug#28904: we don't
need the changed theme when the value recorded for it is going to be
the same as the recorded for the user theme.
* test/lisp/custom-tests.el (custom--test-theme-variables): Get rid of
a portion of the test that will always fail, because the user theme
has priority over every other theme. Expect the test to pass now that
we preserve user customizations after disabling a theme (bug#34027).
