Allow non-file buffers to declare that notification on their
default-directory is sufficient to know when auto-revert updates are
required by setting the new variable `buffer-auto-revert-by-notification'
to non-nil. If nil, the default, then auto-revert will poll
those buffers instead. (bug#35418).
Currently, only Dired sets that variable.

The list of dir local variables to apply is now sorted by the number
of parent modes of the mode used as the key in the association list.
That way when the variables are applied in order the variables from
more specific modes will override those from less specific modes.
If there are directory entries in the list then they are sorted in
order of name length. The list of modes for that dir is then
recursively sorted with the same mechanism. That way variables tied
to a particular subdirectory override those in in a parent directory.
Previously the behaviour didn’t seem to be well defined anyway and was
dependent on the order they appeared in the file. However this order
was changed in version 26.1 and it probably also depended on the
number of dir-local files that are merged.
Bug#33400
* lisp/files.el (dir-locals-get-sort-score, dir-locals-sort-variables)
(dir-locals-read-from-dir): Sort the dir locals so that more precise
modes and directory-specific entries have override lesser ones.
* doc/emacs/custom.texi (Directory Variables): Document the priority.
This fixes bug #35647. State that when indent-tabs-mode is non-nil, spaces
are inserted before the tab rather than the tab being replaced by spaces.

non-nil and remove vestiges of bug#10190.
* doc/lispref/os.texi (Recording Input): Document optional argument
of recent-keys.

* etc/NEWS: Announce it as an incompatible change.
* src/keyboard.c (Frecent_keys): Clarify that returned "events" are
not real events.

Put all information about auto-revert into a section of its own, and
organise the text in a more logical way. Previously it was mainly
described in the section about reverting (bug#35418).
* doc/emacs/files.texi (Files): Adjust menu.
(Reverting, Auto Revert, Autorevert): Add node `Auto Revert' and move
text on that topic from `Reverting', rearranged. Turn the old
`Autorevert' node into a subsection under `Auto Revert'.
* doc/emacs/arevert-xtra.texi (Autorevert): Rename and turn into
subsubsection.
* doc/emacs/buffers.texi (Several Buffers): Adjust references.
* doc/emacs/emacs.texi (Top): Adjust menu.
* doc/emacs/emacs-xtra.texi (Top): Adjust menu.
(Non-File Buffers): Add node and section lines.
* doc/emacs/misc.texi (emacsclient Options):
* doc/emacs/cmdargs.texi (Initial Options): Document that
using --daemon=NAME will need to specify the same NAME when
invoking 'emacscilent'. (Bug#35547)
* doc/lispref/processes.texi (Filter Functions): Use
insert-before-markers in the "ordinary" filter example, like
internal-default-process-filter does.
It is a waste to periodically poll files that use change notification
in auto-revert mode; stop doing that. If no files need polling,
turn off the periodic execution entirely to further avoid wasting power.
Use a timer to inhibit immediate reversion for some time after a
notification, for throttling.
This change does not apply to files in global-auto-revert-mode, where
polling is still necessary. It is disabled by default, and enabled by
setting `auto-revert-avoid-polling' to non-nil.
* lisp/autorevert.el
(toplevel): Require cl-lib.
(auto-revert-avoid-polling, auto-revert--polled-buffers)
(auto-revert--need-polling-p, auto-revert--lockout-interval)

Use auto-revert--polled-buffers and auto-revert--need-polling-p.

Time values are a fundamental data type, and such conversions are hard
to implement within modules because of the various forms of time
values in Emacs Lisp. Adding dedicated conversion functions can
significantly simplify module code dealing with times.
This approach uses nanosecond precision. While Emacs in theory has
support for higher-precision time values, in practice most languages
and standards, such as POSIX, C, Java, and Go, have settled on
nanosecond-precision integers to represent time.
* src/emacs-module.h.in: Add header for struct timespec.
