The current middle-click action of opening a new window on a new
workspace is a bit peculiar; it is also not overly hard to achieve
the same result by moving a new window to the desired workspace or
selecting a workspace before opening a new window. Just opening
a new window is also a more common action, so having a shortcut
available that doesn't require a modifier is a good idea as well;
change the middle-click behavior accordingly.

Having terminal launchers behave differently than any other launchers
is non-obvious and confusing. Remove the special-casing to restore

It's possible that the DBus call goes in timeout (which is bad,

This is done for properly drawing popup menu when arrow rise is 0 (in
case of background menu).
Normally, the menu with arrow rise set to 0 is drawn properly having
all four corners rounded. But when the source(click/arrowOrigin) is
near screen's edges, one of the corners (depending on source's position
and arrow alignment) is drawn right angled.
This happens because the rounded corners are skipped and right angled
arrow is drawn when arrow origin is close to the edges.(That's why when
arrow-rise is 0, it forms right angled corner).
So, a few condition checks are made to ensure that right angled corner
is not drawn.

One of the most frequent complaints about our launching behaviour is
how we handle terminals. Among all MDI applications, the terminal is
the one that is most likely to have lots of semi-independent windows
opened at the same time, and spawning new windows is much more common.
More so, if it does not support tabs.
Therefore, we special case terminal launchers to always create a new
window. It is an application that most non-technical users will not
use, so chances of them being confused by any special behaviour is
expected to be low.

AppDisplay queues a deferred work to load frequently used apps when the

This is also exposed in the ShowOSD DBus method, the "monitor"

You would think we would already do something like this, but apparently

If monitor-changed fires at startup, it will destroy all of the
backgrounds, but since this._isStartup is true, won't recreate any
of them. Additionally, since _bgManagers is indexed by monitor index,
if the primary index is not 0, it could become a sparse array (e.g.
[undefined, undefined, primaryBackground]), and our for loop will
crash trying to access properties of undefined.
Fix both of these issues by always creating background managers for
every monitor, hiding them on startup but only showing them after
the startup animation is complete.
One thing we need to watch out for is that while LayoutManager is
constructing, Main.uiGroup / Main.layoutManager will be undefined,

Our gnome-shell tweener integration has had hooks to determine when
the tweens have started and completed... except that they had a bug
in them. When a tween completed, it queued an idle handler to run
the callback in. If no tweens were running when the idle was removing,
it reset the tween state that contained the idle handler ID. It also
returned false, meaning that the source would always get removed.
If the actor had a tween in-flight when the idle was fired, it wouldn't
clean up after itself. While this is also a simple bug fix, remove the
callback so we don't queue unnecessary, unused idles.

There's a potential race condition in the search code: if we have an
outstanding search call to a provider for search "A", and if before it comes
back we do a subsearch for "AB", we won't have any results to pass along.
Previously, we used an empty list when storing the provider results, so we
effectively told the remote search app to filter through this empty list for
any search results that meet the new query, meaning we showed the user 0
results for the provider in this case.
Now that we don't store an empty list, but instead store `undefined`, this race
raises a warning. Solve it by doing an initial search query in this case
instead.
The search code isn't too smart about chained subsearches: now, if we hit this
race while already on a subsearch, we'll do an initial search for the subsearch
query instead, but that is much better than showing the user nothing. This
could be fixed in the future for a performance improvement.

When a notification becomes expanded, it's either already shown,
or in the process of being shown. Don't set the state to SHOWING
again, which confuses our state machine.
The asynchronous nature of extension loading, session loading, and more,
makes the code racy as to what is initialized first, and hard to debug.
Additionally, since gjs is single-threaded, the only code we're running
in a thread anyway is readdir, which is going to be I/O bound, so the
code here is actually likely to be faster.
Drop this in favor of some good old fashioned synchronous loading.

Long ago, the search system worked in a synchronous manner: providers
were given a query, and results were collected in a single array of
[provider, results] pairs, and then the search display was updated
from that.
We introduced an asynchronous search system when we wanted to potentially
add a Zeitgeist search provider to the Shell in 3.2. For a while, search
providers were either async or sync, which worked by storing a dummy array
in the results, and adding a method for search providers to add results
later.
Later, we removed the search system entirely and ported the remaining
search providers to simply use the API to modify the empty array, but the
remains of the synchronous search system with its silly array still
lingered.
Finally, it's time to modernize. Promises^WCallbacks are the future.
Port the one remaining in-shell search engine (app search) to the new
callback based system, and simplify the remote search system in the
process.
`a + b ? c : d` is parsed as `(a + b) ? c : d`, not the more intuitive

Before, workspacesOnlyOnPrimary was implemented in quite a crazy manner:
* If workspacesOnlyOnPrimary was false, we'd create one WorkspacesView per
monitor, with the primary one being a bit special.
* If workspacesOnlyOnPrimary was true, we'd create one WorkspacesView, and
additional montiors would be handled inside that WorkspacesView as
"extra workspaces".
This caused numerous bugs as the two modes weren't consistently
implemented, and a lot of code was duplicated between all the modes.
Fix this by always creating WorkspaceViews, even if it only handles
one interface. We do this by having two different WorkspacesView-ish
classes: WorkspacesView handles the traditional combination of lots
of workspces, and a new ExtraWorkspaceView is in control of only one
workspace.
Right now, the workspace update code is complex and spread across parts:
WorkspacesView takes a set of workspaces and looks like it owns them, but
WorkspacesDisplay is actually in charge of setting them up and creating
new ones for each WorkspacesView.
Change initialization and handling to move all of the creation/destruction
responsibilities to WorkspacesView.
We pass in monitorIndex into each WorkspacesView, which is a lie in the
workspacesOnlyOnPrimary case, as the primary WorkspacesView currently has
the responsibility of handling the extra workspaces on all the other
monitors. The commit will clean this up and punt the responsibility back
to WorkspacesDisplay.
Not because ClutterActor is bad or wrong, but because I always get
confused on the difference, and having them both in SlideLayout
makes the code a bit easier to read and understand.
The parent SlidingControl had an onOverviewShowing, but we had

When we create a result actor, cache it, so it can be used for
subsearches of the same initial. For now, to keep memory usage
and the stage graph relatively clean, don't persist the actors

This also means that we don't query getResultMetas for items
that we've seen in the same initial search.

The existing provider system is split between a confusing mess of
RemoteSearch, SearchSystem, SearchDisplay, and ViewSelector, partly
because of the vestigal in-shell search system. Move most of the
logic to search.js so it's easier to read.
We fetch and store the list of providers from the search system when we
construct SearchResults, but we never update this list when providers are
changed at runtime, causing various bugs making the search not seem as
snappy as it should be. Make sure to always fetch the list of providers
from the search system.
While the existing comment is correct in that a source's notifications
will be destroyed first, the code takes a shortcut which prevents the
Source::count-updated signal from being emitted. Given that the purpose
of the signal is to keep notification counters up-to-date which is
pointless when the source is about to be destroyed, the shortcut makes
sense; just save notifications explicitly in that case.

oVirt is software for managing medium-to-large scale deployments of
virtual machine guests across multiple hosts. It supports a feature
where users can authenticate with a central server and get
transparently connected to a guest system and then automatically get logged
into that guest to an associated user session.
Guests using old versions of GDM support this single-sign-on capability
by means of a greeter plugin, using the old greeter's extension
API.
This commit adds similar support to the gnome-shell based login screen.
How it works:
* The OVirtCredentialsManager singleton listens for
'org.ovirt.vdsm.Credentials.UserAuthenticated'
D-Bus signal on the system bus from the
'org.ovirt.vdsm.Credentials'
bus name. The service that provides that bus name is called
the oVirt guest agent. It is also responsible for interacting
with the the central server to get user credentials.
* This UserAuthenticated signal passes, as a parameter, the a token
which needs to be passed through to the PAM service that is specifically
set up to integrate with the oVirt authentication architecture.
The singleton object keeps the token internally so it can be queried
later on.
* The OVirtCredentialsManager emits a signal 'user-authenticated' on
it's object once the dbus signal is triggered
* When the 'user-authenticated' signal is emitted, the login screen
tells GDM to start user verification using the PAM service. The
authentication stack of the service includes a PAM module
provided by oVirt that securely retrieves user credentials
from the oVirt guest agent. The PAM module then forwards those
credentials on to other modules in the stack so, e.g.,
the user's gnome keyring can be automatically unlocked.
* In case of the screen shield being visible, it also will react on that
'user-authenticated' signal and lift the shield.
In that case the login screen will check on construction time if
the signal has already been triggered, and a token is available.
If a token is available it will immediately trigger the functionality
as described above.
