It's possible for the surface to be unbound when we send the leave
event; we've called Resource::unbind() of Surface, so the Surface has,
deleteLater called, but it's still a valid object, and the first check
passes.
We get in this situation because when a surface is destroyed, we're
handling text input from the same source event.
Sending a nullpointer is a protocol error, and wayland kindly closes the
connection.
This fixes my constant:

The setRegion call allows a null region. This means nullptr is an
allowed value which can be passed to ConfinedPointer::setRegion and
LockedPointer::setRegion.
In that case we crash if we try to convert the Region into a wl_region.
Thus add proper nullptr check, just like in
PointerConstraints::lockPointer and ::confinePointer.
Auto test adjusted to cover the condition.
Summary:
The pointer constraints protocol is an unstable protocol and thus
the implementation follows the semantics of unstable protocols.
The protocol allows to create a constraint on the pointer - either a
lock or a confinement on a surface. Those are not activated at once, but
when the compositor actively grants it.
During lock no further pointer motion is emitted, during confinement the
pointer is kept in a certain area.
This implements T4451.

Summary:
In SeatInterface we need to get all PointerInterfaces related to a given
Surface (Client) and call a method on it. The implementation we had so
far went through all Pointers and put all PointerInterfaces into a new
temporary QVector. In most cases all we did then was iterating over the
returned vector.
Which means we created a temporary vector for nothing.
This change implements a kind of std::for_each with the constraints of
the previously used pointersForSurface which does the check that Surface
is not null and that the client matches. If a PointerInterface is found
for that, the passed in method is invoked on it.

With this change the generator is able to detect whether an interface
follows the unstable semantics. In that case the header file on server
side looks different. An enum needs to be generated containing the
interface version. Each of the generated classes has a new method
interfaceVersion returning that enum. The ctor of the class is protected
instead of private.
So far only the header side is adjusted. The implementation currently
generates not matching code.
* static void fooCallback definitions added to Private class
* static const foo_listener s_lister added to Private class
* Private::setup generates the foo_add_listner call
* implementation of s_listener added
* base implementation with a TODO marker added for the callbacks
Summary:
Pointer gestures are created for a pointer and there are two types of
gestures: swipe and pinch.
At a given time there can only be one active gesture. The implementation
in SeatInterface ensures that there can only be one active gesture.
Each gesture consists of a start event, 0 to multiple update events and
an end event. The end can also be a cancel. To better support this the
implementation doesn't follow the protocol and splits end and cancel
into dedicated methods in the server side and into dedicated signals in
the client side.

This is ancient code that is outright wrong most of the time and at best
just incredibly unnecessary.
It is also not present in the great majority of frameworks due to this.
Its wrongness comes from the fact that it hardcodes the installation path,
which breaks relocatability of the KF5 tree as it will always attempt to
find the include dir $PREFIX/KF5 (e.g. /usr/include/KF5), which may or may
not exist given that the tree was relocated.
Worse yet, in a cross-building scenario we maybe for example
build on ARM and install to /usr but for cross building take the entire ARM
tree and shift it into /arm/usr/. If we then crossbuild on that tree the
bogus include list in this framework will make sure that we always search
in /usr/include/KF5 and thus potentially load a !ARM header simply because
the relevant ARM header was not installed etc.. Similarly of course a
build in $HOME can pick up /usr/include/KF5 headers because the home ones
are missing, causing unexpected results.
This happens whenever the KDE_INSTALL_INCLUDEDIR_KF5 var is absolute, which
it usually is.
On top of all that the premise of the code in question is flawed. It seeks
to add $PREFIX/$KF5INCLUDES to the search paths (e.g. /usr/include/KF5).
This is unnecessary because the target itself is properly installed via
cmake's install(TARGETS ... EXPORT ...) function [1]. This function has
smart functionality built in which will add the passed INCLUDES destination
to the INTERFACE_INCLUDE_DIRECTORIES property of the targets (i.e. what
the useless code wants to do) [2].
So what happens is that we install the target to the
KF5 locations, which has "include/KF5" as INCLUDES location,
thus causing the correct path to be added to the includes list of the
Targets.cmake file.
In particular thanks to more internal magic in cmake it will do so with
automatically resolved root paths such that the installed tree is
relocatable and able to relatively find the other KF5/* headers. So it
does what the code in question wants to do, just correctly.
Since cmake automatically takes care of injecting $prefix/include/KF5 we
can simply get rid of the wrong custom inejection code. This makes the
generated cmake file find the correct include/KF5/ directory and stops it
from always expecting a /usr/include/KF5/ directory to be present.

CHANGELOG: Improved relocatability of CMake export
The test destroyed the connection prior to destroying registry and event
queue. Thus causing problems. Hopefully this change fixes the segfault
on build.kde.org.
The test has KWayland::Client objects like Registry as member variables
of the test object. This causes the objects to be destroyed with the
dtor after cleanupTestCase is run which destroys the connection and
Wayland server. At least on the CI system this seems to cause problem.
In general our tests do not keep any state around, especially not
KWayland::Client objects. The normal way is to have a new dedicated
client connection for every test method. This test doesn't follow this
approach at all.
In case that this change does not fix the test and still crashes on
build.kde.org the only option is to drop the test and replace it by a
new variant which follows the approach of other tests.
Reorder the cleanup code. It doesn't make sense to delete the client
side objects after deleting the server side objects. This might be a
reason for the failing tests on build.kde.org.

Summary:
By default a panel does not take focus. But there are panels which

Summary:
Especially for Xwayland windows the compositor might not have a themed
icon name. Resulting in a task manager not having dedicated icons for
Xwayland windows.
This change deprecates the way how a compositor is supposed to set the
window icon. Instead of passing the themed icon name, it is now supposed to
pass the QIcon. In case it's a themed icon the existing way to pass to
the client is used.
Otherwise a new event is used to inform the client that there is an icon
- no data is transmitted at this point. The client can then create a
file descriptor and pass it to the compositor. The compositor serializes
the icon into the file descriptor and the client can read from it. This
all happens transparently on client side there is no api change at all.
The writing and reading of the icon is done in a thread. Due to that
Qt5::Concurrent is now a required dependency instead of an optional
dependency.

wl_resource pointer is set to null and the Resource gets delete later.

Summary:
This change implements the zwp_relative_pointer_v1 protocol which allows
to send relative motion events.
The (unstable) protocol consists of a RelativePointerManager which
creates RelativePointers for a given Pointer. This interface currently
only has one event to report the relative motion. It carries the delta,
the non-accelerated-delta and a timestamp in microsends granularity.
On the server side the implementation is mostly internal. Once a
RelativePointerManagerInterface is created one can send relative motion
events through the SeatInterface. The SeatInterface takes care of
sending it to the responding RelativePointerInterface. The protocol does
not restrict the sending of "normal" and relative motion events. Thus it
can be combined in any way one wants. This allows to have a rather
simple implementation. A user of the SeatInterface can just start to
feed the relative motion events (if the information is available) to the
SeatInterface together with the pointer events.
On client side a new RelativePointerManager and RelativePointer class
are added. The RelativePointerManager creates the RelativePointer for a
given Pointer. The event sent to RelativePointer is transformed in a
normal signal.

When changing the selection the previous selection needs to be

not able to accept anything new from the clipboard. The setSelection
didn't cancel it yet, due to that copy from Xwayland to QtWayland
windows doesn't work in KWin as KWin uses the setSelection call for the
Xwayland clipboard.
With this change the cancelling of previous selection is moved into a
dedicated method and called from the normal way and the setSelection

Summary:
This change makes use of the internal key state in better way. If a
key is not considered pressed, no key release is sent. This can happen
for example if the compositor grabs a key press (global shortcut) but not
the release. The Wayland client cannot do anything with the release as it
never got the press. Thus it doesn't make sense to send the release.
Similar if a key is already pressed, it doesn't make sense to send
another press event. This ensures that if the server sends in repeating
key presses they are filtered out. Key repeat is handled on client side.
Also if several physical keys send the same key code, pressing them at
the same time won't send double press/release event.
This change might cause regressions in KWin in case KWin does not handle
the situation correctly. But that would be a bug in KWin which needs to
be fixed there. If it causes regressions the bug might have shown in
other situations as well.

According to the Wayland documentation a data source needs to be
cancelled whenever it is no longer valid. A reason for no longer being
valid is that the data source has been replaced by another data source.
So far KWayland did not implement this aspect which resulted in clipboard
breaking in QtWayland applications. As soon as one copied once from an
application it was no longer possible to paste to it from another
application.
With this change the data source gets properly cancelled and also
ensured that the server code doesn't run into a possible crash condition
when trying to cancel an already unbound data source.

On build.kde.org the Surface is often already destroyed when returning
from waiting on client disconnected.
This change tries to handle the situation better: only if the signal
is not yet emitted, try to wait for it.
Newer Weston renamed the interface to the unstable naming scheme. As
KWayland does not support this interface yet, the tests are failing.
This change skips the test if the Weston is too new and doesn't provide
the expected interface any more.
If the client deletes the currently entered Surface the Pointer should
return null in Pointer::enteredSurface and not invalid memory.
At the same time a now incorrect assert is removed. After the client
deletes the Surface it might still get a left event for the Surface.
In that case a comparison between the enteredSurface and the Surface
from the leave event would fail.

Summary:
This change introduces support for the unstable xdg-shell interface in
the server. The implementation is based on version 5 of the unstable
interface. This is the version used by toolkits like e.g. GTK.
There is also a version 6 of the protocol under development which is
incompatible. This makes it difficult to implement it in a backward
compatible way.
Because of that the implementation is a little bit different to other
interfaces and inspired by the TextInput interfaces:
On client side an XdgShell class is exposed which does not represent
it directly. Instead it delegates everything to an XdgShellUnstableV5
implementation. For the Surface/Popup the same is done.
In the Registry it's possible to create an XdgShell and it accepts
the XdgShellUnstableV5 and in future will accept XdgUnstableV6, etc.
On server side it also follows the approach from TextInput. That is
there is a version enum which gets passed to the factory method in
Display. It currently supports only V5, but in future can be extended
for V6. As there is lots of similar code between wl_shell, xdg_shell
and in future xdg_shell_unstable_v6 a templated GenericShellInterface
class is added which combines the common parts.

When setting the keyboard focus the server needs also to send the current
selection to the client. So far KWayland only sent the selection if it was
set. That is if the last focused client cleared the selection it was not
updated and the client might have had an outdated selection.
To prevent this situation the server now explicitly sends the clear to the
client on enter if there is no selection. Also if the selection is cleared,
the SeatInterface now unsets it's current selection to make sure that the
next focused keyboard will get the clear selection sent.

Summary:
This is a gotcha moment:
1. Create Surface with id 1
2. destroy that Surface
3. Create another Surface
Now if in step 3 the id is by pure chance getting reused and also 1, the
wl_resource pointer of the SurfaceInterface of step 1 and step 3 are
the same. This is rather unexpected and causes problems.
When creating a ShellSurface in step 1 and step 3 it would fail. KWayland
finds a ShellSurface which was already created for the Surface. The same
can happen with QtSurfaceExtensionInterface and PlasmaShellInterface which
also go into error state.
On client side this would trigger a protocol error and terminate the
application. An easy way to reproduce is opening the file open dialog
from within Kate multiple times.
This change addresses this problem by setting the surface pointer in
those classes to null when the parent Surface gets destroyed. Thus
creating a new ShellSurface won't find the old referenced Surface any
more.
For ShellSurface and PlasmaShellSurface a test case is added which hit
the condition without this change. For QtSurfaceExtension we don't have
the client side, so we cannot really simulate the condition.

Summary:
So far for internal cleanup we mostly listen to QObject::destroyed.
When a Resource gets unbind the wl_resource is set to null and the
Resource gets deleteLater. This creates a short time frame when the
Resource is still there, but the wl_resource is null. For most internal
usages the Resource is completely useless at that point and should no
longer be considered. So far it was still considered and could hit
crashers, if a code path did not nullptr check. Unfortunately
libwayland-server is not nullptr safe: if called with a null value it
tends to crash.
So this check introduces a new signal unbound which can be listend to
in addition to the destroyed signal. It's used in SeatInterface for
DataDeviceInterface, where we experienced a crash related to that.
A test case is added which exposes the crash, but it already needs
the unbound signal to get into the crashy condition. The actual crash
is fixed twice - with the help of the unbound signal, but also by
introducing the nullptr check where it's needed.

Summary:
The fact that the buffer is still referenced - that is used - when the
BufferInterface gets destroyed is an error, but it is not fatal.
Unfortunately KWin/Wayland is still hitting this assert from time to
time and the assert is not helping to find the cause as a backtrace
does not show where a reference is still hold.
This change removes the hard assert by a soft warning. The advantage
of the warning is that the compositor is not killed and that we can
observe the reason and find a usage pattern which triggers the condition.
With that we will hopefully be able to find the case where the buffer
is still referenced when being destroyed and fix that.
