It is a very privacy-concerning component, so we will treat it
specifically.
As it is, it will have to come from the --inputmethod argument. We can
work on some UI later on to select which keyboards are available.
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.
In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.
Debugging the panel thumbnails I realised that the setPosition calls
didn't have an effect. This is probably not the only way to fix this bug
but does fix the bug.
At the moment it only brings the position from the interface.
If the Xwayland process crashes, it will bring down the entire session
together with itself. Obviously, we don't want that. At least, Wayland
clients should survive the crash.
This change refactors relevant X11 parts to handle Xwayland crashes in a
less fatal way.
In order to handle Xwayland crashes better, a pair of start() and stop()
methods had been introduced in the Xwayland class to allow starting and
stopping the Xwayland process at any moment.
If we detect that the Xwayland process has crashed, we will immediately
stop the Xwayland server, which in its turn will deactivate the socket
notifier and destroy all connected X11 clients. Unfortunately, a couple
of subtle changes in X11Client::releaseWindow() and Unmanaged::release()
had to be made to ensure that we are left with a valid state after the
Xwayland server has been stopped.
Sub-classes of the AbstractClient class need a valid instance of the
Workspace class to function as desired. We should not create xdg-shell
clients until the workspace is created.
Xwayland can operate in two modes - rootless and rootful. When Xwayland
operates in the rootful mode, a container window is created where all
native X11 clients are placed. The container window is an xdg-toplevel
surface. Most compositors are not interested in rootful mode.
When Xwayland operates in the rootless mode, every X11 window is going
to be represented with a Wayland surface that has no role assigned to it.
In order to associate a wayland surface with an X11 window, Xwayland
will send a client message of type WL_SURFACE_ID.
Since we want Xwayland operate only in rootless mode, the check that
verifies that a newly created xdg-toplevel surface belongs to Xwayland
is pointless. We are never going to hit that case.
Currently in order to load an Xcursor theme, kwin uses libwayland api,
which looks really awkward because of the way how the compositor talks
to itself via the internal connection.
The main motivation behind this change is to limit the usage of kwayland
client api in kwin.
Summary:
Restrict to process with `X-KDE-DBUS-Restricted-Interfaces=org.kde.kwin.Screenshot` in their corresponding Service file,
to take screenshots.
Such a program can now take immediate screenshots.
Adds a utility file to group KService related logic.

The wp_viewporter compositor extension allows clients to crop and scale
their surfaces. It can be especially useful for applications wishing to
reduce their power consumption, e.g. video players, etc.
Given that there is no any direct relationship between the surface size
and the buffer size anymore, we have to use specialized helper methods
for converting coordinates from the surface-local space to buffer pixel
space and vice versa.
There are several ways to handle unmapping of a wl_surface. The first
one is to destroy the associated AbstractClient instance. The second one
is to transition the AbstractClient in a special state.
The problem with the second approach is that it makes animations such as
fade out more difficult to handle since effects in kwin are geared more
towards the first approach (destroying AbstractClient).
Summary:
This change splits the XdgShellClient class to better match existing
abstractions in the xdg-shell protocol and fix a few issues related to
sending configure events.
In the new client classes, configure events are handled differently.
Instead of blocking configure events, we try to send them as late as
possible. Delaying configure events will let us merge changeMaximize()
for X11 clients and Wayland clients and it also fixes the bug where
we don't send the final configure event when user has finished resizing
a window.
Given that configure events are not sent immediately, XdgSurfaceClient
keeps the last requested frame geometry and the last requested client
geometry.
This patch doesn't intend to fix all issues in kwin's implementation of
the xdg-shell protocol. For example, we still handle surface unmapping
very poorly.
Test Plan: Tests pass.

Summary:
Demote the "interface not granted" message from a warning to debug
and improve the wording a bit.
We are listing all the interfaces, it's not like we're not granting an interface
that the application wants, it's that we're not offering an interface to an application
because it didn't opt in.
Only report every miss once, to reduce the noise.

Summary:
KScreenLocker only anymore takes an FD when it tries to lock. The connection
is created and kept internally in KWin.
At the moment we do not do any further checks on the lock but directly hand
over an FD whenever KScreenLocker is about to lock.

xdg-shell stable has been around for quite a while. A quick analysis

Summary:
Currently, we have only one shell client type - XdgShellClient. We use
it when we are dealing with Wayland clients. But it isn't really a good
idea because we may need to support shell surfaces other than xdg-shell
ones, for example input panel surfaces.
In order to make kwin more extensible, this change replaces all usages
of the XdgShellClient class with the AbstractClient class.
Test Plan: Existing tests pass.
