Summary:
This change standardizes the behavior regarding the destructor request.
The destructor should destroy the resource and nothing else. The
Wayland library invokes the static unbind method once the resource is
destroyed. The implementation provided by Resource::Private::unbind
triggers a delete later on the Resource. So there is no need to trigger
a deleteLater from the destructor request callback.
This change adds a generic implementation to Resource::Private which is
now used by all inheriting classes replacing the custom implementations.
Test Plan:
For a few Resources the test is extended to ensure that the Resource
gets deleted on server side.

The text input change creates an additional serial, so the check
for last generated serial on the Display fails. The test is now
adjusted to the new semantics. A more reliable way would be to
verify the serial on the SeatInterface, though.
Summary:
This change introduces support for text input. Text input allows to
compose text on the server (e.g. through a virtual keyboard) and sent
the composed text to the client.
There are multiple interfaces for text input. QtWayland 5.6 uses
wl_text_input, QtWayland 5.7 uses zwp_text_input_v2.
wl_text_input is from pre Wayland-Protocols times and considered as
UnstableV0 in this implementation. The other interface is UnstableV2.
Unfortunately the V2 variant is not yet part of Wayland-Protocols, but
used in Qt.
The implementation hides the different interfaces as good as possible.
The general idea is the same, the differences are rather minor.
This means changes to how interfaces are wrapped normally. On client
side in the Registry a manager is factored which represent either of
the two interfaces. Similar on the server side Display's factory method
takes an argument to decide which interface should be factored. This
way a user of the library can expose both interfaces and thus be
compatible with Qt 5.6 and Qt 5.7 onwards.

Summary:
When destroying a SurfaceInterface all callbacks are getting destroyed.
This used to iterate over the callbacks and performing
wl_resource_destroy on them. This triggered the destroy handler which
removes the resource from the callback list. Which means removing from
the list we are iterating on. This could result in a double delete or
accessing invalid memory.
This change copies all callbacks to a temporary list and clears the
normal lists. So the destroy handler does no longer modify the lists
currently being iterated on.

The ShellSurface might have the resource destroyed, before being deleted,
so there is a short time frame where resource might be null.
Crash was caught by KWin.
Reviewed-By: sebas and notmart
A downstream KWin test shows a possible heap-use-after-free if we
access the wl_client pointer. Basically we get the client disconnected
just before the focused surface gets unbind. Thus for a short moment
the ClientConnection pointer is gone. This needs to be extended with
a test case, but for the moment it should be good enough to get KWin
green again.
Summary:
So far the server component performed manual cleanup in some cases
when a client disconnects. But this is not needed: the Wayland library
calls the static unbind methods which do cleanup. If we cleanup ourselves
this can result in double deletes in the worst case, so let's only use
the Wayland functionality.
Adjusted:
* RegionInterface
* SurfaceInterface
* ShellSurfaceInterface (doesn't take a parent anymore)
* DpmsInterface
* QtSurfaceExtensionInterface
* KeyboardInterface
* PointerInterface
* TouchInterface
* DataOfferInterface
* PlasmaShellSurfaceInterface
For each adjusted case a test case is added to verify that the cleanup
works. Exceptions are DpmsInterface as the actual Resource is not exposed
at all in the Server component and DataOfferInterface as that is server
side created.

From time to time the test is failing on build.kde.org with an ASAN
heap-use-after-free error. From my investigation this seems to be caused
by the OutputDevice being constructed on the stack and being destroyed
while handling Wayland events, but before all are handled.
The test mostly operates on the changed signal. There is also a done
signal emitted later on. Wayland sends the done after a set of changes
is transmitted. Thus the test is adjusted to wait for done instead of
changed. So we can ensure that all events are handled before the object
gets destroyed.
I have never been able to reproduce the problem locally, so I cannot
guarantee that the issue is solved for good. If it still happens more
investigation will be needed.

Summary:
The protocol is extended by a dedicated destructor request. When a
PlasmaWindow is umapped we no longer destroy the resource directly,
but only send the unmap. The client is then supposed to clean up
(which it already did in that case) and will invoke the destructor.
The PlasmaWindowInterface object will be automatically deleted after
the unmap once all resources bound for it are destroyed.
The tests are extended by two new test cases which triggered protocol
errors on the client side prior to this change.

If the focused pointer and keyboard surface is the same we use pointer
clicks as a hint to which child surface should have keyboard focus.
Keyboard focus handling for sub surfaces is rather limited overall.
We just don't have a good model on how to determine which child surface
should get the keyboard focus. When passing focus to a surface there
is no way to know which of the sub-surfaces should get the focus.
Ideally the client should handle this, but that's just not the case.
The best we have is a reference through the pointer. But that's of
course also limited. Keyboard focus passed to the surface for another
reason (Alt+Tab) cannot select the proper sub-surface without interaction
from another input device.

Summary:
The idea behind this change is to make the existance of sub-surfaces
an implementation detail for pointer events. The user of the library
does not need to care about on which sub-surface the pointer is on.
It only needs to care about the main surface and passes the focus to
the main surface.
Internally the PointerInterface takes care of sending the enter to
the sub-surface at the current pointer position. Also whenever the
pointer position changes, the PointerInterface evaluates whether it
triggered a change for the focused sub-surface and sends enter/leave
events accordingly. If the focused sub-surface does not change, it
sends motion events as normally, but of course under consideration
of the sub-surface position.
Overall this means that from pointer usage perspective a user of the
library doesn't need to care about the fact that there are sub-surfaces
at all. The library does the correct thing for it.

Summary:
This change introduces a damage tracking feature in SurfaceInterface.
So far the SurfaceInterface only exposes the damage compared to the
last attached buffer. But this is not always usefull for the user of
the library. E.g. if:
* server renders
* client damages buffer and commits
* client damages buffer and commits
* server wants render
In this situation the last damage information is not helpful to the
user of the library. It would need the combined damage information over
all attached buffers.
The new API combines the damage of the two commits in the example above.
The user of the library can then call resetTrackedDamage once it
processed the current damage (e.g. by updating the OpenGL texture).

Summary:
QtWayland doesn't map the parent sub-surfaces in a sub-surface tree.
According to the spec this would mean also the child sub-surface is not
mapped. But being strict according to the spec will make applications
like SystemSettings fail badly. Embedded child windows will not be
rendered and QtWayland is going to hard freeze. This is not acceptable,
thus we need to workaround this QtWayland bug till it's fixed.
It's worth mentioning that Weston as the reference compositor also
doesn't handle this situation according to spec and renders the
sub-surface. See https://bugs.freedesktop.org/show_bug.cgi?id=94735
The difficult part for the workaround is to determine whether a surface
should be considered unmapped. E.g. when the parent gets unmapped we need
to really unmap it. But what's the difference between an unmapped parent
surface which should be considered mapped and an unmapped parent surface
which should be considered unmapped?
The implementation goes with considering a new sub-surface always as
mapped - independently of whether it ever got a buffer attached. As soon
as it had a buffer attached and it gets unmapped again, it will go back
to a standard conform way.
The behavior now is not standard conform, thus the autotest is adjusted
to have QEXPECT_FAIL for the now no longer standard conform areas.

the input handling as a not mapped sub-surface should not get any input

QtWayland doesn't commit the parent surface when creating a sub-surface.
This results in a QtWayland application to freeze as it renders to the
surface and waits for the frame rendered, which it will never get as the
Compositor waits for the commit on the parent prior to mapping the
sub-surface.
To work around this behavior, we apply the adding/removing directly.
The behavior around this is actually not fully documented, so QtWayland
is not wrong per se. See:
https://lists.freedesktop.org/archives/wayland-devel/2016-March/027540.html
Once this is properly clarified and implemented in the Client, we should
revert this change.
Differential Revision: https://phabricator.kde.org/D1191
The idea behind this signal is to notify whenever the tree of sub
surfaces changes in a way that a repaint of the Surface is required.
Possible situations are:
* surface damaged
* surface unmapped
* subsurface added/removed
* subsurface moved (position changed)
* subsurface stacking changed
Ideally it would be possible to provide the actual area which needs
repainting, but due to the possible complexity of the tree, synced
and desynced changes this doesn't look worth the effort. A user of
the signal might trigger too many repaints with it, but if it really
wants to be only notified about the actual changes, it can just track
the individual sub-surfaces.
When committing the state of a sub-surface, the state should not
be immediately applied if the sub-surface is in synchronized mode.
Instead it should be cached and only applied after the parent surface's
state is applied.
To implement this the Surface::Private has now a third cached state
buffer. When committing the state is either swapped between pending and
current or pending and subSurfacePending. Once the parent state is
applied the state is swapped between subSurfacePending and current.
The logic for applying state changes is changed. Instead of copying the
complete state object, the individual state changes are now copied and the
source gets completely reset to default values. Only the children tree is
copied back, as that list needs to be modified.
The mode is not sufficient to determine whether a SubSurface is in
synchronized mode.
Quoting spec:
"Even if a sub-surface is in desynchronized mode, it will behave as in
synchronized mode, if its parent surface behaves as in synchronized mode.
This rule is applied recursively throughout the tree of surfaces.
This means, that one can set a sub-surface into synchronized mode, and
then assume that all its child and grand-child sub-surfaces are
synchronized, too, without explicitly setting them."
The test application creates a sub-surface tree consisting of overall
three surfaces:
* blue main surface
* red sub surface
* green sub surface to the red sub surface
All surfaces are in synchronized mode. There is a timer to turn the
green surface into yellow after five seconds.
Summary:
The wrapper for wl_surface::set_buffer_scale was still missing.
Main reason for implementation is the need for the added auto-test.

DataDevice exposes new methods to get the DataOffer provided through
drag'n'drop and also signals to indicate the various changes on the
DataDevice during drag'n'drop.
This allows to add a first basic auto test for the drag'n'drop
functionality covering both server and client side.
Summary:
How drag'n'drop works on Wayland:
When a surface has a pointer grab and a button pressed on the surface
(implicit grab) the client can initiate a drag'n'drop operation on the
data device. For this the client needs to provide a data source
describing the data to be transmitted with the drag'n'drop operation.
When a drag'n'drop operation is active all pointer events are interpreted
as part of the drag'n'drop operation, the pointer device is grabbed.
Pointer events are no longer sent to the focused pointer but to the
focused data device. When the pointer moves to another surface an
enter event is sent to a data device for that surface and a leave
event is sent to the data device previously focused. An enter event
carries a data offer which is created from the data source for the
operation.
During pointer motion there is a feedback mechanism. The data offer
can signal to the data source that it can or cannot accept the data
at the current pointer position. This can be used by the client being
dragged from to update the cursor.
The drag'n'drop operation ends with the implicit grab being removed,
that is the pressed pointer button which triggered the operation gets
released. The server sends a drop event to the focused data device.
The data transfer can now be started. For that the receiving client
creates a pipe and passes the file descriptor through the data offer
to the sending data source. The sending client will write into the
file descriptor and close it to finish the transfer.
Drag'n'drop could also be initiated through a touch device grab, but
this is not yet implemented.
The implementation in this change focuses on the adjustments for pointer.
For the user of the library drag'n'drop is implemented in the
SeatInterface. Signals are emitted whenever drag is started or ended.
The interaction for pointer events hardly changes. Motion, button press
and button release can still be indicated in the same way. If a button
release removes the implicit grab the drop is automatically performed,
without the user of the library having to do anything.
The only change during drag and drop for the library user is that
setFocusedPointerSurface is blocked. To update the current drag target
the library user should use setDragTarget. Sending the enter/leave to the
data device gets performed automatically.
The data device which triggered the drag and drop operation is exposed
in the SeatInterface. The user of the library should make sure to render
the additional drag icon provided on the data device. At least QtWayland
based applications will freeze during drag and drop if the icon doesn't
get rendered.
The implementation is currently still lacking the client side and due to
that also auto test. It's currently only tested with QtWayland clients.

A system isn't idle by definition below 5 sec. Before it's not possible
to properly determine whether the user is still interacting with the
system or not. Thus such a short timeout is not sufficient to determine
whether the system is idle.
Furthermore allowing short timeouts like 1 msec can be used to gather
information from the system. It would allow to reconstruct the timestamp
changes on the seat very reliable, which we do not want a Client to know.
And also this can be used to get events on each key press and key release
and the time between each of the events. This can be used to gather
statistics which would in worst case allow to reconstruct what the user
is typing. Determining where a word starts and ends should be relatively
straight forward if you know the timing. With the length of the word and
the statistics of alphabetic distribution it becomes possible to
reconstruct some words. And also individual letters. With enough
statistic and some known words one can determine how long it takes to
press a certain letter. At that point the idle interface would be a
keylogger.
To prevent such attacks the timestamp is now modified to be at least
5 sec. Why 5 sec? Because it's the smallest timestamp used in the
KIdleTime example application which I do not want to break.
5 sec are long enough to destroy this possible attack.

This implements the server part of the screen management protocol. The
protocol is implemented as a wayland protocol.
It provides the following mechanisms:
- a list of outputs, close to wl_output, with additional properties for
enabled, uuid, edid, etc.. These OutputDevices correspond to a
connected output that can be enabled by the compositor, but is not
necessarily currently used for rendering.
- a global OutputManagement, which allows creating config objects, one
per client. The client can make changes to the outputs through
setScale(outputdevice*, scale) for example.
- an OutputConfiguration resource, that can be handed to a client and
used for configuration. Changes are double buffered here. Only after
OutputConfiguration.apply() has been called, the changes are relayed
over the global OutputManagement.
The compositor is responsible to handle changes.
For a more detailed description, see the API docs in especially

* add semicolons after class declarations -- one less thing to fix in the
resulting code

Uses QWidgets to render a very small UI.
* lists each Output
* for each output shows whether dpms is supported
* and which dpms mode it's in
* and provides a button to change the mode
Adding support for a org_kde_kwin_dpms interface. On server side
Dpms is mostly bound to the OutputInterface exposing just a very
small manager. Whether Dpms is supported and which mode is used is
tracked directly on the OutputInterface.
In the header for each request a method is created, with following
features:
* ignores requests working as destructor
* adjusts return type for requests containing newId
* adds QObject *parent = nullptr for requests containing newId
* adds the arguements
* turns arguments from wayland into Qt types
In the cpp the same logic is applied. Methods are not properly
implemented and won't compile in the case of returning.
* parses the protocol
* can derive file name to generate from protocol name
* detects which interface is a global and which one is referenced
* generates client code for global and for resource
* comes with a mapping.txt file to translate wl -> KWayland
The small tool added here allows to automate the process of generating
the boiler plate for an interface. Currently it's able to generate the
Client side code representing a wl_global.
The tool does not get installed, so run it from build directory:
Example usage:
./kwaylandScanner -c Foo -f foo -g wl_foo
This will generate a wrapper for the wl_foo interface in files:
foo.h and foo.cpp
The class is called KWayland::Client::Foo.
The tool will be extended. Following things are on the TODO list:
* parse xml to get the Wayland names
* add listener (if needed)
* generate code for Wayland interfaces representing Resources
* generate the Server boiler plate

* Raises wl_seat supported version to 4 in both server and client
* Raises wl_keyboard supported version to 4 in wl_keyboard
* wl_pointer and wl_touch are still on version 3
* Raises minimum Wayland version to 1.6

the blur to, in case the window is shaped
