Right now, the app folder dialog isn't really a dialog,
since it is actually added to the AppDisplay. Furthermore,
having it added in AppDisplay may mess up with its sizing
calculations, since AppDisplay has a ClutterBinLayout and
the folder dialog has a fairly large minimum size.
Add the folder dialog to the overview group. Next commits
will adjust various actors to be able to better handle it.

Events have a clear and obvious connection to the calendar, and similar
to the Clocks and Weather sections there's a strong link to a particular
application.
Adding them as another section to the right-hand side of the calendar
therefore presents a viable alternative to the old events section.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1282
The idea behind hiding the notifications and media section on days
other than today was that they represent present activity together
with today's events, in contrast to past and future events from
other days.
After events were moved out of the message list, that behavior is
no longer useful: We just guarantee that the left-hand side of the
calendar will always be empty when browsing the calendar.
Adjust to that by removing the limitation by date.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1282
While treating notifications as a type of present event was a neat
concept, there are some issues with it that we never managed to
address (not least the inability to "open" an event).
So remove the current events section from the message list; we'll
bring back events in a different form later.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1282
This comment is no longer correct, we're not inserting any actors here
to adjust for the window border, but we're modifying the allocation of
the children to adjust for that border.
Since that happens in the layout manager anyway, remove the comment
here.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1297
Now that we handle all ClutterClones belonging to the WindowClone pretty
much the same, we can add a generic _addWindow function to WindowClone
which creates the ClutterClone and adds it to the layout manager.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1297
This isn't quite the same as the allocation, but it's what the workspace
actually wants to use given that we use the bounding box of the
WindowClone for all the layout calculation.
So instead of calculating the windowCenter in the WindowClone, make use
of the bounding-box property of the layout manager and return the center
point of that.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1297
Make use of the new bounding-box property we introduced for the
WindowClones layout manager in the last commit.
With this we can remove all the bounding box calculation code from the
WindowClone class and simply use the "notify::bounding-box" signal to
notify changes to our size. To make sure users of the WindowClone don't
break, we now have to convert the layout managers ClutterActorBox in our
getter function to a JS object.
Since we now also don't have to connect to the "destroy" signal of the
attached dialogs anymore, we can remove _disconnectSignals() and only
listen to "destroy" of the toplevel window.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1297
Move the tracking of the bounding box and all the layout related things
out of the WindowClone class and into the layout manager. This allows
the layout manager to keep track of its windows itself and simply notify
the new bounding-box property in case that box changes.

WorkspacesDisplay is a ClutterActor subclass, and overriding
the show and hide methods require chaining up, otherwise the

Unlike the desktop-entry hint, the app name is not optional. That

Since we now have a layout manager for the WindowClone that allows
allocating it a size that isn't the absolute size of the window, we can
now give the WindowClone an artificial size and it will get scaled
accordingly.
So make use of that and stop positioning WindowClones using fixed
position and scale and use a fixed position and fixed size instead. This
will make it easier to use a ClutterLayoutManager to allocate the
WindowClones, because layout managers should only set the allocation of
their children, not the scale.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1294
Since we're going to override the fixed width and height of the
ClutterActor the WindowClone is subclassing, remove those confusing
getter methods for width and height and switch to the public boundingBox
for getting that information.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1294
The getOriginalPosition() API of WindowClone can easily be replaced by
using the existing boundingBox property, which reflects the windows
bounding box in absolute coordinates. This property is also used
everywhere else in the Workspace object, so we can use it here, too.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1294
Change the preferred size functions of the layout manager of window
clones to allow allocating smaller sizes, too. Also scale down the
allocation sizes of the ClutterClones our allocate implementation so
the ClutterClones will scale their texture accordingly.
This will enable us to position the window clones using their allocation
size instead of their scale, which is necessary when introducing a new
ClutterLayoutManager that positions the window clones.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1294
We're going to add a ClutterLayoutManager responsible for allocating the
WindowClones. Since layout managers should only set the allocation of
actors, not the translation or scale, we need to position the
WindowClones using their x, y, width and height properties.
The first step for this is to revert this commit, which switched from
setting fixed positions on WindowClones to using the translation
properties.
This reverts commit 8929c89d1f.

Being able to visualize the actor tree is a handy feature

As explained in the comment in _init() of WindowClone, we hide the
actual clone from picking so it doesn't interfere with XDND.

We currently only remove the screenshot operation from the shooter
map if the color pick operation completed successfully, but not if
it was cancelled. As a result, we now reject any further requests
from the same sender because we assume that there is an ongoing
operation.
Fix this by moving the cleanup to a finally clause that runs for
both code paths.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1288
Right now _createScreenshot() returns a tuple that indicates failure
when a sender requests a screenshot operation before a previously
started operation finished.
However that doesn't work for the PickColor() method, as it uses a
different return type than the other methods.
Address this by returning an error instead, which works in any case;
arguably trying to start multiple operations in parallel is an error
by the caller more than it is a failed operation anyway.

Now that the only user of the IconGrid is AppDisplay, and
it only uses the paginated icon grid, there's no point in
having the two classes split anymore.
In addition to that, future commits will introduce a layout

merging PaginatedIconGrid and IconGrid in the same class will
vastly simplify this transition.
Merge PaginatedIconGrid into IconGrid, and adapt AppDisplay
to this change.

The Frequent apps grid has a few problems:
* On a fresh install there would be no history of app usage so the
applications shown in the grid have no relevance it takes time
to be useful instead of being useful from the start;
* The grid has far too many items in it to be relevant; 24 apps is
well beyond the average use case as most people don't frequently
use that many, so it gets populated with several apps that are
single use (hello xterm);
* The position of items in the grid are always changing based on an
unknown frequency metric (and not by user-intended input) which
makes it a poor way to quickly launch apps as one would have to
constantly learn the positions of the items in the grid;
* Having two app grids is a bit superfluous and needlessly complicates
the app launching navigation: you have to spend time checking the
frequent grid and if it's not there you have to switch over to another
grid and find the app you need in there it's not straightforward.
Remove the Frequent tab and simplify the related code.

With color picking implemented in the compositor, we
can do better than letting the user pick a pixel with
the crosshair cursor, and present them with a preview
of the color that will be selected.
Do this by replacing the cursor with a custom icon and
apply a recoloring effect, where we replace a given color
with the color of the currently hovered pixel (similar
to a green screen).

logExtensionError() currently saves the error message by calling
toString() on the passed error. That's convenient as it allows to
pass a string instead of a "proper" error, but the result isn't
great for the common Error case: Its toString() method prefixes
the message with the error name, which usually is just "Error:".
The plain message is more suitable for displaying it to users,
so use that for Error objects.

For fd.o notifications, we are taking the sender's PID into
account when associating notifications with sources (mainly
to deal with notify-send).
This broke when the implementation under the well-known name

as sender.
Restore the old behavior by resolving the sender PID in the
separate service, and pass it as hint to the implementation
in gnome-shell.

Spidermonkey caches imports, which means that uninstalling an
old extension version and installing a new one doesn't work as
expected: If the previous version was loaded, then its code will
be imported instead.
For the last couple of releases this has been a reliable source
of extension bug reports after major GNOME updates. Thankfully
chrome-gnome-shell removed its update support in favor of our
built-in support now, but users may still use older versions
or perform those actions manually, so it still makes sense to
catch this case and set an appropriate error.

The do-not-disturb button and the contained switch are
tied together via a bidirectional property binding.
However it still matters which objects are used as source
and target, as that will determine the initial state: Right
now the (unchecked) button is used as source, which means
that do-not-disturb is turned off on startup.
We want the state to be preserved, so swap source and target
to let the switch (that is bound to the underlying GSetting)
control the initial state.

by Soup.Session. Doing so also sets a default timeout of 60 seconds.

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.

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.

Just as with the last commit, we should not break the assumption made by

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.

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

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).
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1174
Our intended behavior when bluetooth is turned off is to keep
the menu visible if devices had been set up previously.
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.

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.

In some situations we could end up not with lingering 'view-loaded'

Fix this by removing any lingering signal or later handlers when

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!

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.

It seems there is a weird race condition between Clutter trying to
destroy the keyboard actor and Clutter trying to hide the keyboardBox
container actor: If the keyboardBox is hidden before destroying the
keyboard actor, Clutter doesn't repaint anything and the keyboard
remains visible until something else draws over it.
To fix this issue until we find the underlying Clutter bug, simply
destroy the keyboard actor before hiding the keyboardBox. The order in
which we call these doesn't matter anyway since hideKeyboard(true) hides
the keyboard immediately without an animation.

We're dealing with attached keyboards now using the touch_mode property
of ClutterSeat: If a device has a keyboard attached, the touch-mode is
FALSE and we won't automatically show the OSK on touches, also the
touch-mode gets set to FALSE when an external keyboard is being plugged
in, so that also hides the OSK automatically.
With that, we can now ignore keyboard devices when updating the last
used device and no longer have to special-case our own virtual devices.
Because there was no special-case for the virtual device we use on
Wayland now, this fixes a bug where the keyboard disappeared after
touching keys like Enter or Backspace.

Instead of adding a dragMonitor for every icon in the grid as soon as
one icon is getting dragged, only add a dragMonitor for the icon that is
currently being dragged over (ie. the current drag-target). With a large
number of icons in the iconGrid, this should significantly reduce lags
while dragging.
We can do this by detecting the DnD-entering of an icon or folder using
the `handleDragOver()` callback of drag-targets, adding the dragMonitor
because we know an icon is hovering above the drag-target and then
detecting the DnD-leaving of the drag-target by using the `dragMotion()`
handler, where we remove the dragMonitor again as soon as the
targetActor is no longer our actor (ie. the drag-target).

While it should be impossible to destroy a FolderIcon while a DnD action
is still going on, there might still be rare cases where this happens

So make sure we're on the safe side here and don't potentially leave
dragMonitors around after the icon is destroyed by removing the
dragMonitor inside the onDestroy handler of the FolderIcon, just like we
do for AppIcons.

Blacklist support was added all the way back in commit 1e286e43, but
the code had been defunctional until recently. While uninstalling an

we don't know if an extension was *actually* blacklisted:
The website returns that operation for any extensions for which it
doesn't find any versions that match the shell version. That is, the
most likely reason is that the user updated to a new GNOME release
which the extension doesn't support yet.
It doesn't look like the website is going to change that behavior any
time soon[0], so drop the 'blacklist' handling for the time being.

Since PackageKit 1.11.1, the prompt to install updates on the end
session dialog has been (mostly) broken. The problem is that it only
works if PackageKit is running at the time the end session dialog is
opened; otherwise, our GDBusProxy has invalidated all of its properties,
which we read to see if update is possible. We need to autostart
PackageKit before reading its properties to fix this problem. That would
be easy if we were calling a method to see if an update or distro
upgrade were available, but since we're just checking a property, using
cached properties won't suffice. We'll have to manually check the
property value to ensure we autostart PackageKit.
Most of the code is written by Florian. Thanks Florian!

On X11, _onFocusChanged() updates the input region, as well as the
reactive-ness of the dialog's buttons.
That method is not only used as signal handlers (which are correctly
disconnected when the dialog is hidden), it also runs when the "show"
transition completes.
That's a problem if the transition is still ongoing when the dialog is
hidden, as it will then only complete when it is replaced by the "hide"
transition, after the this._dialog has been reset to null, and trying
to access the dialog's buttons results in an error.
Avoid this by explicitly removing all transition on hide before

There are two ways for applications to provide a high contrast icon:
1. install an icon into the HighContrast theme
2. install a symbolic icon into the default hicolor theme
The latter is preferred nowadays, and implemented in the high-contrast
CSS variant by enforcing the symbolic icon style.
However together with the way we currently enable/disable high-contrast,
this can lead to the following race:
1. the GTK theme is changed from HighContrast
2. we reload the default stylesheet
3. the icon style changes to "regular", so we request a
new icon from the HighContrast icon theme
4. the icon theme is changed from HighContrast
5. we evict existing icons from the cache
6. we reload icons for the new icon theme; however as we
find a pending request (from 3), we re-use it
7. the request from 3 finishes, and we end up with a
wrong icon in the cache
The simplest fix is to change the icon theme before the GTK theme: Unlike the
theme name, the icon style is encoded in the cache key, so we won't re-use
an old (and incorrect) request in that case.

When launching the default calendar application, we special-case

assume that 'evolution-calendar.desktop' exists when evolution does
(even though we ship the .desktop file ourselves, it is considered
invalid if the executable isn't found)

At least for the time being, this looks like the easiest option to

- we could add a systemd unit, but then we'd need to update the

making it necessary for gnome-shell, gnome-shell-extensions and
gnome-session to be updated to 3.36.1 in lockstep
- autostart is problematic as it would make gnome-shell conflict
with other notification daemons; also autostart is most useful
with automatic shutdown, which would require tracking signal
subscriber to determine when the service is unused

This caches GAppInfo so that the compositor thread does not have to perform
costly disk access to load them. Instead, they are loaded from a worker
thread and the ShellAppCache notifies of changes.
To simplify maintenance, ShellAppCache manages this directly and the
existing ShellAppSystem wraps the cache. We may want to graft these
together in the future, but now it provides the easiest way to backport
changes to older Shell releases.
Another source of compositor thread disk access was in determining the
name for an application directory. Translations are provided via GKeyFile
installed in "desktop-directories". Each time we would build the name
for a label (or update it) we would have to load all of these files.
Instead, the ShellAppCache caches that information and updates the cache
in bulk when those change. We can reduce this in the future to do less
work, but chances are these will come together anyway so that is probably
worth fixing if we ever come across it.

Since the FolderViews are not connected to the "installed-changed"
signal, we need to reload their apps by calling _redisplay() when an app
is removed or installed. We can't connect to "installed-changed" inside
FolderView because we need to ensure _redisplay() of the FolderView is
called before AppView tries to access the apps of the folder inside
_refilterApps(). So reload the FolderViews inside AllViews _redisplay()
implementation to ensure everything is up to date before accessing the
apps of the folder.
Since the "apps-changed" signal of FolderIcon now indirectly triggers a
_redisplay() of the FolderViews, the 'changed' handler of FolderView is
now redundant and can be removed. Because of this, we also need to move
the emission of the "apps-changed" signal to the start of the signal
handler to make sure the view is updated before we try to access items
of the view.

However, XSettings is by no mean mandatory for X11 clients and many
legacy X11 clients do not implement XSettings. Those who do always have

We do spawn gsd-xsettings, and watch its name before notifying on the

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

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.
