Summary:
We need to wait till the helper process created the datadevice. For this
we used a while loop. On build.kde.org the test gets stuck in this loop
and times out after 10 minutes.
This change introduces a dedicated signal and we just wait for it. So if
something fails we wait only 5 sec instead of endless. This should help
investigate why the test doesn't work on build.kde.org.
Test Plan: Test works locally

Summary:
implement virtual desktop support for Wayland.
use the new virtual desktop protocol from D12820
The VirtualDesktopManager class needed some big change in order
to accomodate it, which is where most changes are.
Other than that, it's mostly connections to wire up
VirtualDesktopsManager and VirtualDesktopsManagement(the wayland protocol impl)
Depends on D12820
Other notable detail, is the client visibility updated to reflect the presence
of the client in the plasmavirtualdesktop.
(and the unSetDesktop concept)
Test Plan: used a bit a plasma session together with D12820, D13748 and D13746

With the new Wayland only mode we start too fast and it can happen that
the initWithWorkspace is called before the client connection is fully
setup. This would result in a crash in the idletime plugin once it tries
to create a seat.
To prevent this problem the code is split out into a dedicated method
and only invoked if all interfaces have been announced on the internal
connection.
Summary:
Adds XDGV6 support for the kwin side.
Popup placement support is limited to the stuff v5 had,
a simple offset, rather than the awesome new positioner.
But Qt doesn't make use of it yet either.
Also ideally we should do all the positioning before sending the first
configure, but again Qt doesn't actually do anything with that anyway.
Also integrate pinging clients

Summary:
So far KWin did not support the sequence:
1. Create wl_shell
2. Create PlasmaShellSurface
3. Create wl_shell_surface
KWin only supported the case that the PlasmaShellSurface is the last
thing to get created. This is rather limiting and can be considered a
bug. At least we had a QEXPECT_FAIL auto test for this situation. So
it was a known issue.
This change should make it easier to support the QtWayland changes in
Qt 5.8.

Summary:
This allows Client to use the Wayland-specific implementation if there
is no icon geometry set through the X11 way. That way Xwayland windows
have an icon geometry even if Plasma is using Wayland and setting the
icon geometry in the Wayland way. Which is expected as Plasma is
ignorant about the windowing system a PlasmaWindow uses.
In order to move the code from ShellClient to AbstractClient
WaylandServer gained a new findAbstractClient(Surface*) method which
is just like findClient(Surface*) with the difference that it returns
an AbstractClient instead of a ShellClient*.
Test Plan:
minimized/unminimized an X client on Wayland, verified
animation is correct (though broken in general for minimize)

If we try to query before WaylandServer created the KSldApp the service
owner change is never delivered. Thus a delay till we know that the
service is there on Wayland. On X11 the initialization can be done
directly.
To know when the WaylandServer is fully initialized an additional
signal is added to WaylandServer.
Summary:
Most platforms like the nested and virtual do not handle the outputs
themselves and WaylandServer announces the Outputs to Wayland.
So far this was static: at startup it got announced once to Wayland
and any changes were not catched.
This change makes WaylandServer listen to changes to the Screens and
sync them to Wayland.
Unfortunately KWin's internal Screen information is not sufficient to
properly synchronize this to Wayland and also Wayland by not supporting
adding/removing modes does not help.
Thus the solution implemented here is to add new outputs reflecting the
changes and then removing the old ones. This creates situations with more
outputs being present than actually there, but prevents that there are
no outputs at all.
Test Plan: Auto test added which verifies this for the virtual platform

Summary:
The WaylandServer creates the XdgShellV5 interface and hooks it up
to create a ShellSurface whenever an xdg surface or xdg popup is created.
ShellClient gains some new ctors for the different variants and is
adjusted to delegate to xdg surface respectively.
With this change KWin mostly supports xdg-shell protocol. Still missing
is support for the "geometry" request which is rather difficult to
implement in KWin.

This change makes sure that KWin detects that the Wayland server does
not work and terminates the startup early and ensures that it doesn't
crash while going down.
An error message is shown that we could not create the Wayland server.

Summary:
The clipboard sync is done by a dedicated helper binary launched by
KWin. This helper binary is forced to xcb platform to piggy-back on
Qt's implementation of the X11 clipboard. In addition it implements
the Wayland clipboard - which is much simpler. Reading the Wayland
clipboard is based on the implementation in QtWayland.
KWin internally knows the DataDeviceInterface belonging to the helper
application. Whenever an xwayland client is focussed, this DataDevice
is allowed to set the selection and KWin manually updates the current
selection in the SeatInterface. By that the sync from X11 to Wayland
is implemented. When afterwards a Wayland client is selected, it's sent
the current selection which references the X clipboard and a data
transfer can be initiated in the normal Wayland way.
For the other direction KWin sends the current selection to the helper's
DataDevice whenever an xwayland window is focused. The helper application
reads the Wayland clipboard and sets it on the X11 clipboard. Thus the
Wayland clipboard is synced to X11.
The approach used here will also be useful for implementing a clipboard
manager (aka klipper).
Currently the implementation is not yet fully completed. We need to
make sure that the helper application gets restarted in case of a crash.

Summary:
When a shell client got mapped, unmapped and mapped again we emitted
the shellClientAdded signal in WaylandServer again. This resulted in
e.g. Workspace, EffectsHandler, etc. to start managing the window again.
This can be a reason for problems we see with such windows like the
Plasma panel dialog when opened the second time.

Needs extensive testing on real world system as that changes
behavior now.

Summary:
In order to start the WaylandServer in kwin_x11 we need to make sure
that WaylandServer does not start the KScreenLocker integration. On
X11 the lock screen is provided by a different application (in Plasma
by ksmserver).
A new init flag is added to WaylandServer to not integrate with
KScreenLocker. Thus the default is still to integrate with KScreenLocker.
All direct usages of KScreenLocker are guarded to not be called if
the screenlocker integration is not present.

Summary:
This is the first change in a refactoring series. The aim is to:
* rename AbstractBackend to Platform
* move backends/ to plugins/platforms/
* don't bind platforms to Wayland only
* provide a platform plugin for "normal" X11
* share more code between X11 and Wayland
This change moves the platform/backend from waylandServer to Application.
The init of the plugin happens directly in the Application from the
KPluginMetaData. There is no need to externally init it and set the
parent.
WaylandServer::backend() currently just delegates to
kwinApp()->platform(), the idea is to drop this method completely.
The test infrastructure is also adjusted to this change.

This patch implements read access to the outputmanagement interface in
kwin_wayland's drm backend.
- outputdevices are created in DrmOutput, just like the wl_outputs
- wayland_server implements the outputmanagement interface and
- passes the changesets down into the backend
This means that the interface is announced, independently of the DRM
backend, but the actual outputs are currently only there if the DRM
backend is used.
The changes are not applied (passed into the kernel's drm interface
yet). This is obviously work-in-progress, so it's incomplete. Since it
allows us to run kwin[master] with the libkscreen KWayland backend, it's
a significant step allowing testing and further development.

We need to also destroy all idle objects when we tear down the
internal client connection. Otherwise the cleanup tries to free
the object after our Wayland connection is already destroyed.
We announce support for it and depending on whether we have a plugin
or not set the default mode to Server or None.
When a decoration interface is created it gets installed on the
ShellClient. But there it isn't properly used yet as we don't have
support for decorations in ShellClient yet.
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.
This introduces Toplevel::isLockScreen() and Toplevel::isInputMethod(),
this can be used to allow only lockscreen/inputmethods to get input
events and shown when screen is locked.
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.
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.
This allows to check if specific ShellClient is from LockScreen or not,
as well as this adds method to verify if ShellClient is from input
method like maliit.
Now that KWin knows about which window is from Screenlocker it can apply
various security restrictions like no other window then greeter is on
top of it.

REVIEW: 125954
Allows to interact with the Registry for the internal connection in
other parts of KWin and makes it possible to create more than just the
ShmPool for this Registry.
The creation of PlasmaWindowInterface is moved from WaylandServer into
AbstractClient. This allows the sub classes to better control when to
create/destroy the Client.
For creation it's bound to becoming visible - that is Windows which are
only created but never shown are not announced at all.
For Client it's destroyed with the normal tear-down of a Client, for
ShellClient it's destroyed on unmapped (which also means a new one
will be created again in case of another mapping of the surface).
As a side effect, this works around the problem that ShellClients do not
yet get destroyed for QtWayland's menus (needs further investigation).
So far this only allows to trigger show desktop functionality and exports
the state.
In future this should be restricted to just one dedicated desktop shell
process.
Input-method servers, like maliit, need to be known to KWin since KWin
needs to know about virtual keyboards. Virtual keyboards should be shown
as OSD layers, and they are one of the types of windows that actually
should be showable when the lock screen is active.
kwin_wayland --inputmethod /path/to/your/input-server
tries to start the input server. The input-server's window never gets
keyboard focus and is shown on top of all windows except for KWin's
internal clients.
The PlasmaShell interface allows to create a PlasmaShellSurface for a
given Surface. Through this interface the Surface can request:
* a specific position
* a window type
So far only the window types Normal, Panel and Desktop are supported
which is a sufficient subset for getting plasmashell to work.
In future there should be security checks so that only the dedicated
desktop shell can bind these interfaces.
Adds all internal ShellClients into a dedicated list. This ensures that
we don't perform "normal" window management on them.
In addition we add them to the top of the stacking order. This restores
behavior as it is on X11: internal windows are using BypassWindowManagerHint
and thus on top of everything.
The internal used window Id consists of two parts identifiying the
Client and one identifying the Surface. That is the first 16 bits
are set to the ClientConnection, the last 16 bits are taken from
the Surface id. As the Surface id is 32 bits, but we only use 16 bits
there is a chance of overlap. So this might need some improvement.
If the ShellClient got created for a Qt internal window, we try to
find the QWindow and if we get one, we use the geometry directly as
it got set by KWin in the first place.
Also a windowId() is added to ShellClient which can be used by the
effect system to find an EffectWindow. If it's an internal QWindow
we just use that window id. For other clients we still need some
smart solution.
QtWayland and mesa might dead lock KWin if we start rendering a QWindow
before Qt/Mesa got the last frame callback. They perform blocking wayland
event reading on the main gui thread which makes it impossible for KWin
to do the compositing and send the callback.
To workaround this problem we fake a frameRendered directly after each
damage event for a Qt internal window. Unfortunately this is not yet
completely sufficient, thus we also need to ensure that the wayland
events are processed before any events are processed which would cause
a repaint and block. Thus we first flush QtWayland's wl_display and then
our Server connection. If there were any damage events we can be sure
that the frameRendered is sent before Qt attempts to render.
QtWayland only creates popup windows if they have a parent QWindow or
if there is any window which had input. It's not enough to fake an
enter, it needs to be either a pointer button press or key press.
As KWin's useraction menu doesn't have a parent and we most likely
never send a pointer press to any QWindow it doesn't get shown. To
circumvent this we create a dummy window and fake a button press/release
on the window. After that Qt is tricked into believing there's a parent
window and shows the popup.
Faking the input is only done with at least Qt 5.5 as QtWayland crashes
on pointer event without a keymap being installed. As KWin does not yet
send keymaps we better disable the dangerous code path. With Qt 5.5 the
crash condition is fixed.
