5e254666b0 messageTray: Add missing property getter
gjs has gotten less forgiving about missing getters/setters, and
commit 6aa1b817 missed the missing getter in the base policy class.

Most notifications use a policy subclass that already provides a
getter, but at least Main.notify() and friends don't; unbreak them
by fixing the base class.

d3880c0bff main: Unset the right prevFocus actor after the focus stack got shifted
When a modal that's not on top of the modalActorFocusStack gets popped,
we shift the focus stack as described in popModal() to ensure the chain
remains correct. That however destroys the association of a modal actor
and its prevFocus actor on the focus stack, because the prevFocus actors
are now moved to different entries of the stack.

Now when a prevFocus actor gets destroyed, we don't handle that case
correctly and search for the modal actor that was associated with the
prevFocus actor before the stack was shifted, which means we end up
unsetting the wrong prevFocus actor.

So fix that and search the stack for the prevFocus actor which is being
destroyed instead to unset the correct entry.

Thanks to Florian Müllner for figuring out the actual issue and
proposing this fix.

2e80995f19 overviewControls: Remove transitions before updating adjustment value
The workspace switcher blocks state updates while the indicator is
animating. Since commit 9c1940ef9d the indicator is considered to
be animating when the workspace adjustment's value doesn't equal the
active workspace.

There is one case though where this breaks badly: When a workspace
is inserted before the active one, the adjustment's upper and value
properties are changed without transitions. But if that change happens
while there's an ongoing transition to the previously active workspace,
the value gets out of sync with the active workspace and we end up
blocking state updates indefinitely.

Fix this by removing any transitions before setting the adjustment
value.

49d6db34b7 altTab: Set allocation before allocating children
Just as with the last commit, we should not break the assumption made by
Clutter that parents have their allocation set before their children get
allocated, so fix that here, too.

In this case we have to fix it by chaining up to the parent vfunc
override and updating the allocation once more before allocating the
`this._label` child.

JS: migrate from the global window to globalThis
As of mozjs68 (gjs-1.64) `globalThis` is recommended over `window` and
it makes more sense in this context anyways. Migrate the few instances
of `window` we use and adjust the eslint configuration.

`window` will continue to resolve to `globalThis`, so this won't affect

d94d0f60c8 calendar: Do less work in hasEvents()
getEvents() filters all events for the given range and sorts the result.

That's more than we need when checking whether there are any events,
where we only care that there's at least one event in the range.

function, so hasEvents() can return after at most one iteration.

6aa1b817c9 messageTray: Make NotificationPolicy properties read-only
These properties are never written; in the base class they are always
their default values, and in the subclasses the getters are overridden.

This will be necessary because GJS is adding checks to make sure that
readable properties always have a getter, writable properties always
have a setter, and that the variations of camelCase/snake_case are
handled correctly. It's supposedly backwards compatible, but that
assumes that code is not doing things like forgetting a setter on a
writable property. (If the missing setter had ever been called, it might
have led to a crash, which is why we've made this change.)

This is the minimally invasive patch which should work with both older
and newer versions of GJS. If you decide to require GJS 1.65.2, then
you'll also be able to remove the getters from NotificationPolicy as
well.

167bc080d9 appDisplay: Reorganize AppDisplay actor hierarchy
Right now, the actor hierarchy is such that the scroll view
does not contain the actual grid. It looks as follows:

              StScrollView
                    ↓
               StBoxLayout
                    ↓
                ShellStack
                ↓        ↓
   PaginatedIconGrid     StWidget

This hierarchy can be slightly reorganized by changing it to be as
follows:

            ShellStack
             ↓     ↓
   StScrollView   StWidget
        ↓
   StBoxLayout
        ↓
 PaginatedIconGrid

This will simplify future work where the PaginatedIconGrid will be
an implementation of StScrollable, in which case we'll be able to
simply remove the StBoxLayout from there.

If a search provider is installed by an app which is blacklisted for the

also filter built-in search providers, if any of them end up needing to

21de88c3ba bluetooth: Do not update hadSetupDevices on adapter changes
While we now deal more gracefully with adapter removals, we can
still mess up the hadSetupDevices tracking:

As adapters become available before any devices, we'll always
reset the setting to false when Bluetooth is turned on. And if
no set up device happens to be in range, it will still be false
when Bluetooth is turned off again.

To address that, only update the setting if we have an adapter
(like we do now) and we had one before (so it wasn't the adapter
itself that changed).

Our intended behavior when bluetooth is turned off is to keep

However since gnome-bluetooth@c437c729, devices are removed
first before removing the default adapter, so we now end up
always setting the property to false before checking for it.

Fix this by deferring all model changes to an idle, so that
we can process them as a unit. Do the same for proxy property
changes, as those may trigger a row-removal.

a0def23940 main: Don't override DesktopAppInfo desktop if already GNOME
During the shell initialization we call the (deprecated) function to
override the Desktop environment in Gio DesktopAppInfo to make sure that
applications are correctly shown (as per commit b2fbf5a2), however this
might break the cases in which $XDG_CURRENT_DESKTOP is already set and
contains GNOME (given that is now a list).

In Ubuntu this is in fact set to: ubuntu:GNOME.
Now, if an application contains NotShowIn=ubuntu, the key will be ignored by
the shell, and the application is still listed everywhere.

So, override the DesktopAppInfo desktop environment only in the case that
the current desktop is not already GNOME.

At the current date I think we could just safely get rid of this override at
all, but there could be still cases where it still might be useful, like when
running as nested in some other environment, so keeping it.

e.g. after a minute after the activities overview was already closed.

Fix this by removing any lingering signal or later handlers when
unmapping.

764527c8c9 js: Promisify async operations
Promises make asynchronous operations easier to manage, in particular
when used through the async/await syntax that allows for asynchronous
code to closely resemble synchronous one.

gjs has included a Gio._promisify() helper for a while now, which
monkey-patches methods that follow GIO's async pattern to return a
Promise when called without a callback argument.

Use that to get rid of all those GAsyncReadyCallbacks!

5c33fe4a0a appDisplay: Don't start animation from the 'paint' signal
Starting the animation from the actor 'paint' signal has various
unwanted consequences, such as sometimes trigger a
clutter_actor_queue_relayout() during the paint phase. One unwanted
consequence was that an offscreen actor effect was disabled during
painting, meaning the effect would begin being active, but later during
the post-paint processing being disabled. The caused said effect to push
an offscreen framebuffer to the paint context, but then just destroy it
instead of popping it. When this happened, we'd end up trying to operate
on a framebuffer that may had been finalized, or not, depending on the
garbage collector. Sometimes, for some users, this caused a segmentation
fault when trying to pop a matrix from the framebuffer matrix stack.

Deal with this more properly, by using the 'view-loaded' signal to wait
with animation until the view is loaded, as well as using MetaLater to
schedule the start of the animation.

For when a view was signalled to be ready, we're in a state where we can
start animation before the next frame as the layout is ready, but when
not, we have to add back the "hack" where we must wait for one frame for
the target icon positions to be up to date. Do this by adding a
MetaLater IDLE callback that starts the animation *after* the next
frame. This also needs the old 'opacity = 0' work around to not show an
incorrect first frame.
