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.
This introduces an own QPA plugin for KWin. QtWayland's plugin is not
a good solution for KWin as QtWayland is meant for Wayland clients and
not for a Wayland server. Given that it makes more sense to have a very
minimal QPA plugin which supports the use cases we actually have.
With our own QPA plugin we should be able to improve the following
areas:
* no need to create Wayland server before QApplication
* Qt::BypassWindowManagerHint can be supported
* no workaround for creating OpenGL context in main thread
* sharing OpenGL context with Qt
* OpenGL context for Qt on libhybris backend
The plugin supports so far the following features:
* creating a QPlatformWindow using KWayland::Client (ShellSurface)
* creating a QPlatformBackingStore using a ShmPool
* creating a QPlatformOpenGLContext with Wayland::EGL
* or creating a QPlatformOpenGLContext which shares with KWin's scene
* creating a QPlatformScreen for each KWayland::Client::Output
* QPlatformNativeInterface compatible to QtWayland
If we were on e.g. vt 1 and pressed Ctrl+Alt+F1 KWin broke as it
disabled rendering for vt switch and vt switched to vt 1, which
obviously failed.
So let's check whether it's going to switch to the vt we are already
on and ignore surch requests.
Each of the backends becomes a plugin. This allows kwin_wayland to load
the requested plugin and kwin itself doesn't need to link all the
libraries needed. E.g. libdrm is no longer linked if running kwin_x11.
Also this allows to create backends for the non-standard EGL platforms
(examples could be raspberrypi or Android devices).
A new Singleton VirtualTerminal is added. It interacts with Logind to
get the VTNr to take over. To get the signal to release and acquire the
VT we use a signalfd with a QSocketNotifier to monitor for signals. The
used signals must be blocked for all threads prior to startup otherwise
they are delivered to secondary threads causing issues.
The AbstractBackend provides a virtual method to create the Screens.
A concrete backend can implement this method to create the backend
specific Screens instance.
This removes the casting logic from Screens::create.
The AbstractBackend registers itself in the WaylandServer allowing
external users to easily get to the backend and not needing to test
manually which backend is used.
Xcb::GeometryHints is a convenient wrapper around the size hints
as described in ICCCM combined with the sanity checks so far applied
by KWin after reading the property.
Instead of accessing the members of the property structure, we are
now using the convenience methods.
During ::manage no further actions are triggered when reading the
size hints. Only when they are read later on the previous checks
are applied. During ::manage they can be ignored as it had a dedicated
isManaged check.
The method ::resizeWithCheck got a new argument of type xcb_gravity_t
which defaults to 0. This is needed from ::configureRequest which so
far temporarily changed the xSizeHints structure. By passing as an
argument this is no longer needed.

means any GPL). Decoration clients will come later.

enabled by default, but will be made configurable soon. There is a known
issue with an incorrect geometry shown with konsole, but that's its fault,
and I'll get to that shortly (xterm does the right thing).
Disclaimer:
If it jams - force it. If it breaks, it probably needed replacing anyway.
