e087a3666b Fix regression caused by backward compatibility support in data source
We should only enforce the check whether a data source has set the
actions for drag on drop on a selection if it's at least version 3. For
backward compatibility we used to set a default action which would
ensure that a version <3 and >3 client can interact with each other. But
due to that the action was set to a default value which breaks any
selection. Sorry about that.

This change ensures the backward compatibility behavior does not break
selection.

As the regression causes all clients to quit it is a severe regression
which requires fast action. Due to that I'm doing a maintainer push
without review. I encourage everyone to do a post commit review.

Sorry for not noticing the regression before. The backward compatibility
was the last thing I added in that patch set and apparently I did not
run all tests again.

42432a14fc Add support for version 3 of data device manager interface
Summary:
The main difference compared to version 2 is additional drag and drop
actions. The source and destination can negotiate whether the data
should be copied or moved or the user should be asked for either or.
This seems to be important for GTK, but is not yet implemented in Qt.

The main motivation for adding support is that it is required by SDL to
launch on Wayland.

20c53ee098 Fix ASAN warnings in XDGForeignV2Interface
Summary:
The current code captures a char* from a wayland event in a lambda.
By creating the QString first when we capture that by value we'll
implicitly shallow copy it.

The other issue was
someHash.erase(it);
*it->foo();

Even though where the iterator points to is still valid, the iterator
itself is an object that gets modified in erase which ASAN didn't like.

Design rationale:
Could be it's own class with Display as an arg, but we need the lifespan

needs to be set after we're started but before clients connect.

Better to enfore rules with code than with documentation.

I'm filtering by interface name as there isn't any other good
identifier of what a wl_global refers to, even if you could assume
you can cast the userdata to a Server::Global.

665c0535fe Add support for zwp_idle_inhibit_manager_v1
Summary:
This protocol allows to indicate that a wl_surface should inhibit idle
actions such as DPMS, screen locking if the surface is visible.

The protocol is quite simple: it just creates an IdleInhibitor for a
Surface. If such an IdleInhibitor exists the Surface is considered to
inhibit idle.

On the server side it is also exposed like that through the API. The
IdleInhibitorInterface is private to the library and only
SurfaceInterface is extended to expose whether it currently inhibits
idle.

f5cfe92b8a [server] Support inhibiting the IdleInterface
Summary:
This is a preparation step to support idle_inhibit_unstable_v1 protocol.
As in Plasma powermanagement, screen locking, dpms, etc. is not
controlled by the wayland compositor but by external components through
the IdleTimeout interface the compositor needs a way to inhibit the idle
timeouts. So once idle_inhibit_unstable_v1 is implemented the compositor
can hook this up to the inhibit API in IdleInterface and thus inhibit
powermanagement, etc. as requested by the idle_inhibit_unstable_v1
protocol.

The added API is straight forward:
 * inhibit: inhibits idle timeouts
 * uninhibit: uninhibits again
 * inhibit and uninhibit must be called in pairs, so twice inhibit,
means uninhibit must be called twice
 * isInhibited: whether it's inhibited
 * and a signal that it changed

The signal is mostly used internally to stop the timers.

Test Plan: Test case extended

9feb359676 Wayland foreign protocol
Summary:
Implement the "foreign" wayland protocol.
A client can export a surface with an unique string as handle,
then another client can refer to that surface and set an own surface as
child of that surface.
Potential use cases are out-of-process dialogs, such as file dialogs,
meant to be used by sandboxed processes that may not have the access
it needs to implement such dialogs.
The handle needs to be shared between the processes with other means,
such as dbus or command line paramenters.

The public api of the server side only tracks parent/child relationships as this is the only data kwin would need it for, the rest of the api is not exported so should be safer from eventual protocol changes

Test Plan:
the autotest works, but has a lot of random crashes when deleting surfaces,
unfortunately backtraces don't tell much and the crashes never occur when running into valgrind
behavior may still be wrong, depending on how the protocol is supposed
to work if more clients try to set the same exported surface as parent

6b460f9a7f Only send OutputConfig sendApplied / sendFailed to the right resource
Summary:
I don't understand the original logic.
s_allResources contains /every/ resource, not just outputconfigurations.

Sending org_kde_kwin_outputconfiguration_send_applied to a wl_surface (for example),
results in an error.

The reason kwin doesn't currently crash is because we don't actually send
applied/failed after setting outputs. (which is another bug)

Test Plan: The existing unit test still passes.

01cace30dd Don't crash if a client (legally) uses deleted global contrast manager
Summary:
There is a race condition in the following situation:

    - Server creates a global
    - Client binds to that global (making a new resource for that
global)
    Simultaneously:
    - The client uses this resource
    - The server deletes the global

This was fixed for Blur, but as mention in that commit can also happen here.

e8850b014c Don't crash if a client (legally) uses a deleted global
Summary:
There is a race condition in the following situation:

- Server creates a global
- Client binds to that global (making a new resource for that global)
Simultaneously:
- The client uses this resource
- The server deletes the global

We then process an event for a resource linked to a deleted global.

This is noted in the specification, the client documentation says:
"The object remains valid and requests to the object will be
ignored until the client destroys it, to avoid races between the global
going away and a client sending a request to it. "

KWayland does not handle this at all.

The global's user data refer to our C++ wrapper
The resource's user data refer to *the same* C++ wrapper

When the global is deleted the resource user data now refers to garbage.

To fix the issue, instead of setting the resource userdata to the
global, we set it to a smartpointer to the global stored on the heap.

We can then validate if our global is still valid.

Theoretically this applies to every global

Practically there are only 3 globals that don't have the lifespan of the
server. Output (which is read only and doesn't matter), Blur and
BackgroundContrast.

Blur resets it's global when a screen geometry changes.

Unfotunately this exactly at the same time that Plasmashell is
doing a lot of processing and creating some blurs.

3c67cc1399 Support XDG v6
Summary:

The main clever part that's not just boring boiler plate is how we
handle the structure change
A surface now has an XDGSurface which then has a an Xdg TopLevel or a
Xdg Popup

We need to fit this into the public API which assumes a surface has a
Surface or a Popup.
The old Surface is similar to the new TopLevel.

The shoehorning works by relying on the fact that a surface without a
role is pretty useless.

Clients create the surface implicitly with the toplevel or implicitly
with the popup.
The server only announced it has a new "XdgSurface" when it gets a new
zxdg_surface_get_toplevel.

----

Popup decisions:
- On popup creation the server should copy the current info from the
positioner and then it gets deleted. Given kwaylands job is to keep
state, we expose all these parameter via popup.

- Due to this positioner is not exposed as a resource anywhere.

- Server API is 100% backwards compatiable.
i.e new code will work identically with v5 clients.

- Client API is not.  Grabs are called separately from the constructor,
and the parent surface changed to an xdgsurface, not a raw surface.
V5 code still works as-is, just not with the new constructors.

It seemed better to match the v6 (and what will be the stable v7) than
to try and do hacks and lose functionality.
Given the client needs to change the code to opt into V6 anyway. I don't
think this is a huge problem.

Test Plan: Current test still passes.

f1491e009e Treat input RGB buffers as premultiplied
Summary:
Currently the server treats incoming buffers as not premultiplied.

KWayland::Client sends data that is ARGB32 and ARGB32_Premultiplied as
the same
WL_SHM_FORMAT_ARGB8888.

According to a post on wayland-devel by Fredrik Höglund, all RGB data
should be treated as premultiplied, which matches what Qt is doing.

Client now performs a conversion rather than sending
mismatched data,

Note: This commit will still breaks a bunch of tests in
kwin as it compares the server output to a fixed
QImage with a format.

Test Plan:
Existing tests pass

Modified surface test to check the pixel data relative to the output
QImage format
not the input format (i.e both input from ARGB32 and
ARGB32_Premultiplied) should
both end up in a QImage with format Premultiplied with premultiplied
values.

The existing test was confirming that data was corrupted, checking that
even though
the output format was not pre-multiplied, the data was.

c6b085f5eb [client] Track all created ConnectionThreads and add API to access them
Summary:
This is change needed by KWin. KWin has the problem that it destroys its
internal Wayland connection (KWin as client for KWin as server) before
shutting down the application. Other external libraries loaded into KWin
(e.g. breeze window decoration) are unloaded later on, then try to clean
up their Wayland resources and crash KWin due to accessing a no longer
valid Wayland connection.

With the help of this new API KWin can access all connections during
the clean up and destroy them before shutting down the Wayland server and
thus exit cleanly.

9266a94400 [server] Send keyboard leave when client destroys the focused surface
Summary:
This is a change inspired by https://bugreports.qt.io/browse/QTBUG-61930.
When Qt closes a window due to a key press event it starts to repeat the
event as KWayland does not send a keyboard leave event. Weston on the
other hand does send out the keyboard leave. In my opinion it doesn't
make much sense to send out the keyboard leave in this situation and in
my opinion that is a client bug, but if it makes clients happy we can
send them the keyboard leave. Similar this should be done for pointer,
touch, etc.

67521b975b Validate surface is valid when sending TextInput leave event
Summary:
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:
"Did the Wayland server die" error messages when running clients.

Test Plan:
Got errors after setting up qt virtual keyboard.
Had reproducible case.
Restarted kwin after this patch, now doesn't crash.

b44a8fb556 Implementation of PointerConstraints protcol
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.

c72510c932 [server] Reduce overhead of pointersForSurface
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.

a3a7356995 Implementation of PointerGestures protocol
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.

99bcb89c3b Remove /KF5 include directory injection
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.

d92592a291 Support passing generic QIcon through PlasmaWindow interface
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.

Summary:
In the situation that a wl_client gets destroyed while still
wl_resources are around it can happen that one of them calls into the
ClientConnection during the cleanup handling which gets triggered at the
same time. This can then trigger a crash.

This change uses deleteLater for the ClientConnection and sets the hold
wl_client pointer to null instead of deleting directly. So the
ClientConnection is still around while the Resources gets cleaned up.
This is similar to the cleanup of Resource where on unbind the
wl_resource pointer is set to null and the Resource gets delete later.

a96776ac0e Implement support for the relative pointer protocol
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.

9f3d6c8f84 [server] Cancel previous selection from SeatInterface::setSelection
Summary:
When changing the selection the previous selection needs to be
cancelled. This is already done in the "normal" updating of the
selection. If the previous selection doesn't get cancelled QtWayland is
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
way.

25dbc84dbc [server] Send key events to all wl_keyboard resources of a client
Summary:
This is what Weston does. With this change clients can create multiple
wl_keyboard instances and thus get events reported to all of them. This
will be needed to e.g. support KModifierKeyInfo on Wayland.

Similar changes are probably also needed for pointer and touch.

Test Plan:
Auto test for seat still passes. A custom change to kscreenlocker
is able to report whether caps lock is on with this change.

9e8f123513 [server] Don't send key release for not pressed keys and no double key press
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.

BUG: 366625
