Ensures that all Wayland objects are destroyed and the cleanup handling
is performed before tearing down the Compositor. This fixes for example
a crash if a Surface with a Shadow is still around at tear down.
WaitForFinished blocks our main thread, but Xwayland wants to talk
to Wayland and blocks as well. So let's ensure events are processed
while terminating Xwayland.
Some effects do X11 calls in their cleanup code through external
libraries (e.g. KSelectionOwner). As we cannot control that we need
to ensure the effects are unloaded prior to destroying the Xwayland
connection.
We need to destroy the ClientConnections we create. Also we need
to disconnect our Xwayland error handling before destroying it, otherwise
it would trigger the abort for crashing Xwayland.
During Compositor tear down Xwayland is already destroyed. Thus it
doesn't make sense to try to delete the support properties: either
it freezes in xcb or it crashes because the connection is null.
At the same time we also ensure that the connection internally is
reset to null. Note: the one in kwinglobals.h caches and could cause
use-after-free errors. Any tear-down code must be migrated to
kwinApp()->x11Connection().
We need to destroy the compositor after Xwayland terminated and after
the internal Wayland connection is destroyed. This means when destroying
the Workspace we may no longer destroy the Compositor at the same time.
Also we need to ensure that other tear down functionality doesn't call
into the no longer existing internal client connection.
With this change kwin doesn't crash when exiting with Wayland and/or
X11 windows still open.
Methods are no longer virtual. The only x11 specific usage in these
methods (resizeInc) is replaced by a virtual method. Default resize
increments is QSize(1,1) for AbstractClient.
Don't emit both geometryShapeChanged and geometryChanged: the one
is set up to call the other.
Also adjust tests because maximize changes triggers too many geometry
changed signals.
Method no longer virtual and only implemented in AbstractClient.
The implementaton works in a generic way nowadyas.
Added an autotest for the basic packTo behavior for packing against
a screen border. Packing towards other clients still needs adjustments
in the Placement code.
The signals operate on AbstractClient nowadays, so we can have one
implementation for both Client and ShellClient.
Only X specific connections are only done for Client.
So far only moving through useractions menu is possible and only through
cursor control (mouse events are lost).
A basic first autotest is added to validate the moving of Windows.
The problem we had was closing a glxgears through an Aurorae theme
crashed KWin inside QtQuick.
This test case simulates the sequence:
1. starts glxgears
2. wait till we have a Client for it
3. send mouse move to guessed close button position
4. send mouse press/release at that position
5. verify the window is closed
6. verify glxgears exits
With the given commit reverted this crashes, with it in place it passes.
Please note: on CI it might fail as glxgears is not yet installed. [1]
Also we cannot enforce using Aurorae from the test yet, though on
the CI system it should get picked automatically as no other deco
plugin should be installed.

If the size is the same it's basically just a window movement. That's
nothing we need to roundtrip to the client, but can adjust the geometry
change directly.
The quick tiling test is adjusted to test this together with
sendToScreen. Each window is also sent to the next screen to verify the
state doesn't change and geometry is updated.
Note: the flag for quick maximization seems to get lost in this setup.
Very basic: all screens have same size and are ordered from left to
right. It's mostly meant to allow easy test cases with multi-screen.
The quick tiling test demonstrates how it's used.
This is needed to properly restore to a valid geometry after quick
maximizing. Note: this is not yet perfect, actually it should be done
after initial placing, which means we do need a manage method like
Client.
The autotest for quick tiling is extended to cover maximize changes
and cover this case.
Base test verifies the quick tile positions. No maximization or direct
state changes tested yet.
Required to have Toplevel and AbstractClient exported. Otherwise we
cannot use the SignalSpy.
As expected in a025791d7b the tests
fail on the CI system due to llvmpipe. Let's try whether enforcing
O2 makes them run, if not update to switch to Q is following.
If the surface indicates that it doesn't want keyboard focus we shouldn't
give it keyboard focus.
This was a problem with Kate's autocompletion tool tip windows.

This is the beginning of a new testing era for KWin: finally we are
able to test against a running KWin. This works by making use of the
new virtual framebuffer backend for Wayland. It starts a specific
Application subclass which is mostly a fork of ApplicationWayland.
The individual tests are able to influence the socket name and the
size of the virtual screen. This is supposed to be done in
initTestCase. To know when KWin is fully started one can use the
workspaceCreated signal of KWin::Application. KWin is not started in
another process, but the kwin library is used, so the test has pretty
much full introspection to everything going on inside KWin. It can
access the Workspace, WaylandServer, fake input events through
InputRedirection and so on.
Once the test KWin is running it's possible to connect to it using
KWayland::Client library. This allows to introspect the Workspace
to see whether all worked as expected (e.g. correct stacking order,
active window and so on).
This first autotest is mostly meant to illustrate how to setup a
test and how one can use KWayland::Client to interact with the mock
KWin. For more tests it is suggested to move the connections to the
Wayland server in the init() and cleanup() methods.
The change also affects the qpa plugin: the specific check to only
run in binaries called kwin_wayland doesn't hold any more. This can
now be overwritten by an env variable.
Please note that this first test will probably fail in the CI system
as it might not have XWayland which is needed by KWin.
