Make the rx `or' and `seq' forms accept zero arguments to produce a
never-matching regexp and an empty string, respectively.
* lisp/emacs-lisp/rx.el (rx-constituents, rx-or): Permit zero args.
(rx): Amend doc string for `or' and `seq'.

* etc/NEWS (Changes in Specialized Modes and Packages): Mention the change.
Make `auto-revert-avoid-polling' have effect in global-auto-revert-mode.
Buffers actually handled by that mode are marked with a non-nil value
of `auto-revert--global-mode'. When global-auto-revert-mode is
entered, eligible buffers are marked in that way, and hooks are set up
to mark new buffers and take care of buffers whose file names change.
This way the existing poll-avoidance logic can be used, since the
entire set of buffers in auto-revert is known.
A new hook, `after-set-visited-file-name-hook', was added to handle
the case when the file name of a tracked buffer changes.
* lisp/autorevert.el (auto-revert-avoid-polling): Amend doc string.
(auto-revert--global-mode): New buffer-local variable.
(global-auto-revert-mode): Mark existing buffers and set up hooks when
mode is entered; do the opposite when exited.

(auto-revert--set-visited-file-name-advice): New functions.
(auto-revert--polled-buffers, auto-revert--need-polling-p)
(auto-revert-notify-handler)
(auto-revert-active-p): Modify logic to cover global-auto-revert-mode.
* lisp/files.el (after-set-visited-file-name-hook): New hook.
(set-visited-file-name-hook): Call new hook.
* test/lisp/autorevert-tests.el (top): Use lexical-binding.
(auto-revert-test--write-file, auto-revert-test--buffer-string)
(auto-revert-test--wait-for, auto-revert-test--wait-for-buffer-text)
(auto-revert-test05-global-notify): New test.
* doc/lispref/hooks.texi (Standard Hooks):
Mention new hook (in a comment, since it's unclear whether it should
actually be documented here)
* etc/NEWS (Changes in Specialized Modes and Packages): Update entry.
* test/lisp/autorevert-tests.el (auto-revert--deftest-remote):
Fix typo.
(auto-revert-test02-auto-revert-deleted-file): On emba, there are
no stopped events.
Emacs_Pix_Container is a pointer to a struct representing pixmap data
on the backend. Emacs_Pix_Context is the context for the
bitmap/pixmap on the backend. Only w32 currently makes this
distinction; they are otherwise the same type.
* src/dispextern.h: Remove XImagePtr in favor of
using XImage* directly. Rename XImagePtr_or_DC to Emacs_Pix_Context.
[HAVE_X_WINDOWS] Alias Emacs_Pix_Container and
Emacs_Pix_Context to XImage*.
[HAVE_NS] Alias Emacs_Pix_Container and Emacs_Pix_Context to trivial
Emacs_Pixmap definition.
[HAVE_NTGUI]: Alias Emacs_Pix_Container to XImage* and
Emacs_Pix_Context to HDC.
* src/dispextern.h:
* src/image.c: Use Emacs_Pix_Container over XImagePtr and
Emacs_Pix_Context over XImagePtr_or_DC.
* src/dispextern.h [HAVE_X_WINDOWS]: Alias Emacs_GC to XGCValues.
[!HAVE_X_WINDOWS]: Define Emacs_GC, GCForeground, and GCBackground.

* src/w32term.c: Use Emacs_GC over XGCValues. Do not set unused font
field.
* src/xfaces.c: Use Emacs_GC over XGCValues and GC.
* lisp/filenotify.el (file-notify-callback):
Comment out condition that does not seem to make any sense. All it
seems to do is allowing notifications for files on the form DIR/X/X
when we really just are watching DIR/X/Y.
* lisp/vc/log-view.el (log-view-diff, log-view-diff-changeset):
* doc/emacs/maintaining.texi (VC Change Log): Document behavior of
log-view-diff at the beginning and the end of the log buffer
when the region is active. (Bug#35624)
* lisp/vc/vc-git.el (vc-git-print-log): Insert newline at the
beginning to enable the feature of diffing with the working revision.
* lisp/cus-edit.el (custom-browse-insert-prefix): Remove XEmacs
compat code and make obsolete.
(custom-group-value-create): Use `insert' directly.
* lisp/emacs-lisp/elint.el (elint-check-conditional-form): Don't
refer to function that doesn't have an if any more.
* lisp/gnus/gnus-group.el (gnus-group-sort-flat): As
gnus-newsrc-hashtb is now a real (unsorted) hash table, use
gnus-group-list to maintain group sort order.
(gnus-group-sort-selected-flat): Ditto.
* lisp/gnus/gnus-start.el (gnus-subscribe-alphabetically): Simplify
function using seq-find.
(gnus-subscribe-killed, gnus-subscribe-zombies): Use cl-pushnew to
avoid adding duplicates (can happen when un/subscribing multiple
times to one group).
* lisp/arc-mode.el (arc-insert-unibyte): Rename from
insert-unibyte, make into a function, and remove the superfluous
string-to-multibyte. Change callers throughout the file.
(hs-set-up-overlay, hs-adjust-block-beginning): Use non-nil default for
function variables, so `add-function` can be used on them.
(hs-toggle-hiding): Make it work for mouse bindings as well.
(hs-minor-mode-map): Use it for the mouse binding.
(hs-grok-mode-type): Use bound-and-true-p.
(hs-life-goes-on): Use `declare` for the debug spec.
(hs-mouse-toggle-hiding): Make it an obsolete alias.

New macros.
(x_cr_destroy_frame_context) [USE_CAIRO]: Rename from x_cr_destroy_surface.
All Uses changed. Don't use FRAME_CR_SURFACE. Make non-static.
(x_cr_update_surface_desired_size) [USE_CAIRO]: New function.
(x_begin_cr_clip) [USE_CAIRO]: Create Xlib surface if Xdbe is in use.
Use FRAME_CR_SURFACE_DESIRED_WIDTH and FRAME_CR_SURFACE_DESIRED_HEIGHT.
(x_end_cr_clip) [USE_CAIRO]: Call x_mark_frame_dirty if Xdbe is in use.
(x_cr_draw_frame, x_cr_export_frames) [USE_CAIRO]: Save and restore cairo
context instead of freeing and clearing it.
(x_update_begin) [USE_CAIRO]: Don't create cairo surface here.
(show_back_buffer) [USE_CAIRO]: Call cairo_surface_flush before swapping.
(x_update_end) [USE_CAIRO]: Don't copy image surface if Xdbe is in use.
Get image surface by cairo_get_target instead of FRAME_CR_SURFACE.
(x_scroll_run) [USE_CAIRO]: Use XCopyArea if Xdbe is in use.
(handle_one_xevent) [USE_CAIRO] <ConfigureNotify>: Call
x_cr_update_surface_desired_size instead of x_cr_destroy_surface.
(x_free_frame_resources) [USE_CAIRO]: Call x_cr_destroy_frame_context instead
of x_free_cr_resources.
* src/xfns.c (set_up_x_back_buffer, tear_down_x_back_buffer) [USE_CAIRO]:
Call x_cr_destroy_frame_context.
This is a different fix for bug#34909, which should also fix bug#35739.
Our downloading code used to automatically decode the result according
to the usual heuristics for files. This caused problems when we later
needed to save the data in a file that needed to be byte-for-byte
equal to the original in order to pass the signature verification,
especially because we didn't keep track of which coding-system was
used to decode the data.
(package--unless-error): New macro extracted from
package--with-response-buffer-1, so that we can specify edebug and
indent specs.
(package--with-response-buffer-1): Use it. More importantly, change
code so it runs `body` in a unibyte buffer with undecoded data.
(package--download-one-archive): Don't encode with utf-8 since the data
is not decoded yet.
(describe-package-1): Explicitly decode the readem.txt files here.
* lisp/url/url-handlers.el (url-insert-file-contents): Use it.
(url-insert): Don't decode if buffer is unibyte.
* lisp/url/url-http.el (url-http--insert-file-helper): New function,
extracted from url-insert-file-contents.
Prefer librsvg for display of splash.svg
When both librsvg and Imagemagick are available, Emacs should
prefer librsvg to render SVG images. However, Emacs was using
Imagemagick to render its own splash.svg file because
image-type-from-file-header returned nil for that file.
* lisp/image.el (image-type-from-buffer)
(image-type-from-file-header): Look at the first 8192 bytes of
the image, not just the first 256. For Emacs’s own splash.svg
file, image-type-header-regexps needs to look at 939 bytes.
8192 bytes is a reasonable number nowadays given typical file
system design.
* test/lisp/image-tests.el (image-tests--emacs-images-directory):
New contant.
(image-type-from-file-header-test): New test.
In the bug scenario, the second and subsequent noise macros with parentheses
were getting font-lock-type-face.
* lisp/progmodes/cc-engine.el (c-end-of-token)
(c-forward-noise-clause-not-macro-decl): New functions.
(c-find-decl-prefix-search): Handle noise macros by skipping over them.
(c-forward-decl-or-cast-1): In the loop checking for types, skip over all
consecutive noise macros with parens, not just one.
* src/image.c (initialize_image_type): Test if the type is in
Vlibrary_cache up front, and return true without calling the
'init' method if the type was already initialized.
* lisp/net/tramp-compat.el (format-spec): Do not require advice, cl-lib,
custom, password-cache, timer and ucs-normalize.
* lisp/net/tramp-gvfs.el: Do not require zeroconf. Declare
zeroconf-* functions.
(tramp-gvfs-enabled): Autoload `zeroconf-init'.
* lisp/net/tramp-sh.el: Do not require dired.
* lisp/net/tramp.el (tramp-get-debug-buffer): Do not require outline.
(tramp-file-name-for-operation): Extend docstring.
(tramp-parse-netrc): Do not require netrc. Autoload `netrc-parse'.
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.
* lisp/autorevert.el (auto-revert-buffers):
Modify condition for using notification.
* lisp/files.el (buffer-auto-revert-by-notification): New variable.
* lisp/dired.el (dired-mode): Set buffer-auto-revert-by-notification.
* doc/emacs/arevert-xtra.texi (Non-File Buffers): Document new variable.
* etc/NEWS (Changes in Specialized Modes and Packages): Describe new variable.
