With Xwayland started on demand, mutter/gnome-shell will spawn Xwayland
and GNOME settings daemon Xsettings.
Currently, gnome-shell uses a timeout of 5 seconds before canceling the
launch and declare failure to start X11 services.
While 5 seconds may seem like a lot of time, when this is executed on a
virtual machine part of a QA tests under load, this causes random
failures.
There is no good value here, we could increase the timeout but it will
always remain racy. Instead, remove the timeout, systemd itself already
has a timeout mechanism (with a much longer wait time).
Thanks to Benjamin Berg <bberg@redhat.com> for finding the root cause
and suggesting the fix.

On systems/setups not using systemd, a failure to start gsd-xsettings
with NOT_SUPPORTED does not denote a failure to start Xwayland, just
that we're not using systemd.
In that case, we should just ignore the error, otherwise it will prevent
Xwayland to start on such systems/setups without systemd.
Thanks to Rose Kunkel (@rosekunkel) for spotting the issue/suggesting
the fix.

If for some reason the xserver failed to start, mutter/gnome-shell
should not attempt to connect to the X11 display otherwise it will
lock up in XCB.
An indication of such a premature failure of the xserver is when the X11
services fail to start.
Return the status so that the caller can cancel the connection in time
and avoid the lockup of mutter/gnome-shell in case of failure.
This, however, makes the X11 services a critical component to start
Xwayland, meaning that a failure to start those services for any other
reason than the xserver failing to start would still prevent Xwayland
and therefore X11 clients to run in Wayland. This is however a lesser
issue than mutter/gnome-shell locking up.
This basically reverts commit a96753f0 - "windowManager: X11 can work
without gsd-xsettings".

Change behavior on pressing Super+Number in Activities/Overview mode
so that the overview mode is hidden and application can be used.
This makes it consistent with clicking icon in the dash.

Currently, gnome-shell uses the wrong scrolling direction for
horizontal scrolling events.
When dx < 0 for a smooth scroll event, then the scrolling direction is
supposed to be Clutter.ScrollDirection.LEFT, instead of
Clutter.ScrollDirection.RIGHT, as dx is smaller than 0.
Fix this issue by swapping the values LEFT and RIGHT.

So far, we couldn't allow workspace scrolling outside the overview
because scroll events were always sent to clients. However mutter
was changed recently to pass on scroll events when the mouse button
modifier (usually super) is pressed, which allows us to enable the
same workspace scrolling as in the overview now.

When logging out or terminating gnome-shell, mutter will unmanage all
open windows, triggering the window-close animation in gnome-shell and
very quickly after that emitting "kill-window-effects". That means we'll
call _destroyWindowDone() to cleanup our animation data, but at this
point the MetaWindow of the window is already gone, so we get an error
that get_meta_window() returns NULL.
Fix that by checking whether get_meta_window() returned NULL and if it
did, don't access the window.

To do this, we now wait for the start/stop job to complete. We also have
two targets in gnome-session to ensure that everything is working as
expected.
In order to start the services, we simply request the
gnome-session-x11-services-ready.target unit, and wait for it to become
available. To stop, we use the gnome-session-x11-services.target unit
which should stop all services in a way that is entirely race free.
This requires both gnome-session and gnome-settings-daemon changes to
work (which are in the corresponding merge requests).

Now that we properly notify mutter about when a size-change animation
has ended, it should never happen that a new size-change animation is
started without the last one being cancelled (ie. 'kill-window-effects'
being emitted).
This means there should also never be an old animationInfo attached to a
window actor, so warn in case we still find one when starting the
animation.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1251
We're currently using the hack of telling mutter that our effect is
completed (even though it isn't) in order to unfreeze updates of the
window actor.
This causes a bug with detecting the wl_outputs a window is
visible on, because the MetaWindowActor emits its "effects-completed"
signal too early, making Mutter update the wl_outputs while we're doing
the animation.
Now since meta_wayland_actor_surface_is_on_logical_monitor() uses the
transformed position and size of the MetaSurfaceActor and is being
called right after we setup the animation (but before it actually
starts, that happens at the next paint cycle) it will use a "very wrong"
rectangle: The transformation has been set to move the actor back to its
old position, and while we did already unfreeze updates and called
clutter_actor_set_position() in meta_window_actor_sync_actor_geometry(),
the actual allocation is not updated yet; this makes
clutter_actor_get_transformed_position() return a position including in
the new transformation, but not including the new allocation, and the
rectangle ends up being moved to the next monitor or completely out of
the stage.
To fix this issue properly, we need to decouple unfreezing actor updates
from emitting the "effects-completed" signal, which is now possible with
the new meta_window_actor_freeze() and meta_window_actor_thaw() APIs. So
use those new methods to freeze and thaw actor updates ourselves and
make sure to call shellwm.completed_size_change() only after the
animation has finished.

It might be that we receive a "kill-window-effects" signal between the
emission of the "size-change" and the "size-changed" signal.
In this case we already have the animationInfo attached to the window
actor, so we should also remove it.

Since commit 0ecddafc20 gsd-xsettings startup has been made conditional
on the systemd user instance being available at runtime. While that is
correct, it means that completing xwayland startup is also conditional
now.
We always want xwayland startup to go ahead, so wait for the XSettings
plugin to appear on the bus when gsd-xsettings is launched by gnome-session
and complete the task immediately if startup fails.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1252
These paths are meant for Xwayland, not for X11 compositors being restarted
through alt-f2 + r. Maybe some signal analogous to init-xserver should be
added for Xwayland shutdown paths, but this signal we are currently
listening for is backend agnostic.
Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/2329
Currently, a failure to start the Systemd unit `gsd-xsettings.target`
would be considered a failure to start Xwayland.
That means that if `gsd-xsettings.target` fails to start for whatever
reason, no X11 client can be used on Wayland.
However, XSettings is by no mean mandatory for X11 clients and many
legacy X11 clients do not implement XSettings. Those who do always have
a fallback path and therefore can still work without XSettings.
Make a failure to start the Systemd unit `gsd-xsettings.target` non
blocking for Xwayland, and just log a warning message.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/1065
We do spawn gsd-xsettings, and watch its name before notifying on the
given task, so the mutter bits can proceed with X11 startup.
One notable change is that we only start gsd-xsettings, instead of the
generic gnome-session-x11-services target. We do so as we have to wait
on a dbus name to appear in order to deem the initialization done, and
making it all depend on gsd-xsettings seems tidier.
Less notably, we also use ::shutdown-xserver to shutdown the related
services. Its major benefit is that it'd allow us to ensure the olderly
shutdown of those services, but it's unused at the moment.

When a window is being resized by the compositor, with Wayland the
compositor first asks the window to change its size and emits the
"size-change" signal, and then emits the "size-changed" signal after
the window acknowledges the new size. To show a fancy resize animation,
gnome-shell creates a "screenshot" of the resizing window on the
"size-change" signal, and later animates that "screenshot" to the new
window size on the "size-changed" signal.
Now if a client is not responding to our requests asking it to change
its size, we get a "size-change" signal and start showing the
window-clone, but never a "size-changed" signal, animating and hiding
the clone again. This causes a so called "ghost window" that is shown
above everything else and never disappears again.
To fix that, start showing the window clone once we get the
"size-changed" signal instead of the "size-change" signal. This makes
sure the window actually updates its size and the clone is going to be
hidden again.

This reverts commit c0c027c608. Because for
some reason animating external opacity and position is still incurring
internal repaints, which disables offscreening and makes fading of
overlapping actors look wrong. `ON_IDLE` should be fixed in mutter before
it is used (in boxpointer at least) again.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/2270
To bypass offscreening in cases where continuous animation is happening.
Offscreening is slower in such cases so this reduces the render time of
animations within offscreenable actors.
On an i7-7700 this reduces the render time of boxpointers for example by
25-30%.

xgettext gained some support for template strings, and no longer
fails when encountering '/' somewhere between backticks.
Unfortunately its support is still buggy as hell, and it is now
silently dropping translatable strings, yay. I hate making the
code worse, but until xgettext really gets its shit together,
the only viable way forward seems to be to not use template
strings in any files listed in POTFILES.

Since ES5, trailing commas in arrays and object literals are valid.
We generally haven't used them so far, but they are actually a good
idea, as they make additions and removals in diffs much cleaner.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
ES6 allows to omit property names where they match the name of the
assigned variable, which makes code less redunant and thus cleaner.
We will soon enforce that in our eslint rules, so make sure we use
the shorthand wherever possible.
