guix (like nix) used a separate prefix for each package. Thus the header
files for
qtdeclarative are in /gnu/store/…-qtdeclarative-5.9.1/include/qt5/ while
the ones for
qtbase are in /gnu/store/…-base-5.9.1/include/qt5/. This means that
*each* dependency's include directory must be specified. This is in
contrast to a "normal" Unix-system, where all includes end up in
/usr/include/qt5 and missing to defined some include-dependencies does
often not raise an error.

The load method and updateLayout ensure the virtual desktop information
is synced to RootInfo and thus to other X11 applications. Thus we need
to call it again when initing X11.

It's confusing to search for usages of ClientList::Iterator and then
discover it's all just commented out. Before falling another time over
it: let's remove it.
Summary:
So far the method only operated on X11 clients. So when the last desktop
got removed Wayland clients were still on it. As the auto test showed:
this results in a crash.
Credits go to code coverage as it showed that area as red, which made me
look on it and realize this must be broken.

The FreeBSD build is currently failing with:
kwingltexture_p.h:83:23: error: no function named 'cleanupGL' with type
'void ()' was found in the specified scope
friend void KWin::cleanupGL();
This change hopefully addresses the problem.
The connect to Compositor::sceneCreated must be disconnected again,
otherwise a restart of the Compositor results in Workspace being created
again.
Thanks to our autotests for finding this problem!
The integrationTest function takes a new optional argument whether the
test supports a Wayland Only mode. If that's the case the test is
compiled twice, once (as always) as "foo" with XWayland support and
once as "foo_waylandonly" without XWayland support.
This way we can ensure that our code always supports both modes. The
tests found multiple issues. At the moment fast running tests are
sporadically crashing on tear down. This needs further investigation.
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.
The operation mode X11 and Wayland is no longer supported and probably
hasn't been supported for the last few years. But now there is the
possibility to run Wayland only, so introduce this as a dedicated new
OperationMode.
Summary:
Unfortunately a rather large change which required more refactoring than
initially expected. The main problem was that some parts needed to go
into platformsupport so that the platform plugins can link them. Due to
the rather monolithic nature of scene_opengl.h a few changes were
required:
* SceneOpenGL::Texture -> SceneOpenGLTexture
* SceneOpenGL::TexturePrivate -> SceneOpenGLTexturePrivate
* texture based code into dedicated files
* SwapProfiler code into dedicated files
* SwapProfiler only used in x11 variants
* Safety checks for OpenGL scene moved into the new plugin
* signal declared in SceneOpenGL moved to Scene, so that we don't need
to include SceneOpenGL in composite
Test Plan: Nested OpenGL compositor works

Summary:
The xStackingOrder unlike indicated by it's name is relevant for both
X11 and Wayland and contains the stacking order of the windows used for
compositing.
So far it was determined whether it needs to be recreated based on
whether an xcb query is pending. This change introduces a boolean
variable to check whether the stacking order is dirty and guards the X11
specific code to only be run if we have an X11 connection.
This is to my current knowledge the last remaining issue where X11 was
used during the normal Wayland operation mode. Now it should be possible
to re-order the Workspace startup [1] and try to run kwin_wayland without
Wayland support.
[1] Workspace::Workspace and Workspace::init is still highly X11
specific and needs to be split into X11 only and general parts.

Summary:
If an Effect has replaced the TabBox and wants to react on mouse events
the EffectsHandlerImpl also has an X11Filter, so we only need to make
sure the events go to that filter.
Motion: TabBox did not filter out, so events will go to the Effects
filter.
Press/Release: TabBox should not operate if Effects take the events.
The events are filtered out by Effects if there is a grab, so just
check for that and go out. Effects will take care.

If the system has a virtual device and KWin is run on virtual platform
we can assume the user intended that KWin should use the virtual device
and not a render node of the system.
This might fix the random test failures on build.kde.org (T6546).
Summary:
The base idea behind this change is to keep the system responsive no
matter what other processes do. All input and rendering needs to go
through the windowing system, so keeping it responsive is important.
Currently KWin competes with all other processes for resources and this
can render the system unusable. Consider some processes running amok. In
this case the user might not be able to easily close the applications as
KWin does not get the cpu time to perform the input tasks requested by
the user.
Or in the case of playing a demanding game it is important that KWin
gets scheduled to forward the pointer input events. The user doesn't
want that the game (or another process) wins against the windowing
sytem.
The disadvantage is that KWin always wins against other processes with
real time scheduling. This could result in KWin running amok stalling
the system. On the other hand this is no change to the current situation
as if KWin runs amok the sytem is unusable.
The change uses libcap to set CAP_SYS_NICE on kwin_wayland executable.
KWin_wayland on start sets the scheduling policy to SCHED_RR with the
lowest possible priority. Thus any other SCHED_RR process will win
against KWin. So real time processes are not affected by this change!
After adjusting the scheduling (which requires CAP_SYS_NICE) KWin drops
this capability again.
Test Plan:
Verified that KWin adjusts the scheduler, that it is not passed
to child processes, that the capability gets dropped and not passed to
child processes.

Instead of calling reconfigure() on screen size changes, which deletes
and recreates the effect, we can just update the one texture that's mapped to
the screen size.

From the wayland commit.
>What surprises me is that BlurManager recreates for Output changes.
>That sounds like a bug in KWin (or an area which could be improved).
I had thought the same and wrote this (though wanted to have kwayland fixed first)
Test Plan:
Logged in and out (my screen resizes on startup due to scaling)
Tested on my X machine by turning a screen off. Nothing broke, plasma
panels looked the same.
Note: Eike tried this patch last week and claimed kwin still crashed.
We don't have a backtrace so it could have been something unrelated,
applied wrong or that he was deliberately lying to wind me up.

Similar to the Blur patch. Arguably rven less reason as this doesn't

We don't need to delete and recreate the entire effect every time the
screen changes; This deletes the wayland global which causes quite a bit
of extra work for the clients.

Changed resolution under X, and scale under wayland

Summary:
The ObscurringWindows are a hack to make it more unlikely that the
desktop wallpaper becomes visible while switching desktops. This was
introduced in 2001 with SVN revision 90111
(git d194f74314).
In 2001 desktop switching was probably a costly action where it was not
possible to just reorder the desktop in one frame. Nowadays we use
mostly compositing and with compositing the ObscurringWindows are
already disabled. But even in the case that no compositing is used I
consider it as very unlikely that the desktop becomes visible during the
switching. Given that I think it's time to remove this legacy solution.

Summary:
Creating the X11Filter directly on startup caused a regression as the
filter got too early in the chain and stole events from the
XInputIntegrationFilter. We don't need the filter all the time, but only
when we have established the TabBox grab. Likewise we can destroy the
filter again when releasing the TabBox grab. So it's much more
encapsulated now.

Summary:
So far both Workspace and Toplevel emitted signals for every property
notify event on the root window and the respective Toplevel windows. The
signals were only used in EffectsHandlerImpl to forward to the effect
system in case the property which changed is registered by an effect.
This change introduces a dedicated event filter for this which is only
created in EffectsHandlerImpl in case an X11 connection is available. It
supports a restart of the X11 system.
The signals used so far are removed from Workspace and Toplevel.

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

Some distributions (e.g. Arch, FreeBSD) call the DMZ-White cursor theme
Vanilla-DMZ. Due to that our tests are failing even if the correct theme
is installed (see also T6623). This change tries to detect whether
DMZ-White is installed by looking into the GenericDataLocation. If not
found we set to Vanilla-DMZ. No guarantee that the check works for all
setups, but it's only tests...
Seems to have been used in old compositing kcm, documented as DBus API.
But Workspace doesn't expose a DBus interface anymore and our new DBus
interface does not call this method -> it is dead.
Summary:
The code ifdefed by ENABLE_TRANSIENCY_CHECK does no longer compile and
has not compiled since the switch to Qt 5 and KF5 as it still uses
kDebug and (worse) kDBacktrace. There are several other changes which
broke the code and I failed trying to get it to compile again. It's a
classic example of bitrot happening to code which is never getting
compiled.
As this has not been in a state which could compile for at least several
years, I think it's best to completely remove it.
