A test to simulate auto-hiding panels. Preparation step for making the
slidingpopups effect working again for auto-hiding panels.
The test case simulates creating a panel at the screen edge, hides it
through the property and shows it again through the edge.
Summary:
The WaylandServer creates the XdgShellV5 interface and hooks it up
to create a ShellSurface whenever an xdg surface or xdg popup is created.
ShellClient gains some new ctors for the different variants and is
adjusted to delegate to xdg surface respectively.
With this change KWin mostly supports xdg-shell protocol. Still missing
is support for the "geometry" request which is rather difficult to
implement in KWin.

This allows effects to animate when a window is shown again and when
a window gets hidden but not yet closed/destroyed. This situation
happens on X11 for e.g. auto hiding panels and on Wayland for pretty
much any window which properly unmaps (windowHidden) prior to destroy.

Summary:
So far when a ShellClient got unmapped ready_for_painting was set to
false. That is the ShellClient was treated in the same way as a not
yet shown window. It was completely excluded from painting, a close
animation impossible.
This change makes use of the functionality available in
Client::hiddenInternal(). The window is considered as hidden, thus
still excluded from e.g. getting input events, but could be rendered
any time as we still have a previous window pixmap (if referenced).
This allows to have it considered in the rendering pass, but effects
still cannot make use of it as that state is not yet exposed to the
effects.

The struts test is extended by a setup containing two horizontal
screens, bottom aligned with the left screen smaller than the right.
Thus there is a dead area in the top left corner. In addition there's
a panel on top left screen.
Apparently KWin allowed windows to open in the dead area. The test
case reconstructs this by opening a window with the same size hints,
but in the test it's working correctly.
A few more cases where we need to ensure that the created window is
destroyed before going into next test method.
Interesting observation: the generated window ids are identical.
Possible problem with KWayland::ClientConnection?
New test method which verifies that a newly mapped window is rendered
correctly, that cursor image set on it is rendered correctly, also when
pointer moves.
Summary:
Many tests create a Wayland window, render it and then wait till it's
created in KWin as a ShellClient. To reduce code duplication the test
helper provides helper methods to wait for the next ShellClient to be
shown and to directly render and wait for the window for that to be
shown.

Summary:
A new namespace KWin::Test is added which provides a few helper
functions. It makes it easy to setup a KWayland client connection with
the base set to be able to create a Surface and flags to create
additional interfaces. This replaces the KWayland connection dance in
init() methods. For cleanup() there is also a dedicated helper function.
In addition there are helper functions to:
* render a surface
* create a surface
* create a shell surface
* flush the wayland client connection
* access to the created interfaces - for compatibility with existing code
The idea is to extend this Test library also for other common use cases
like creating an X11 connection and X11 windows, etc.

Summary:
The idea behind this autotest is inspired by bug 356328 which produced
incorrect rendering results. Also it's inspired by openQA which performs
image reference comparisons.
This test case tries to go further. It creates reference images which
must match the rendering result exactly. So far the test case verifies
the start condition - kwin started and one frame is rendered with default
cursor in the middle of the screen. And it verifies the moving of the
cursor without any windows shown. Whenever the cursor moves a repaint
should be triggered and the old and new area should be properly
repainted.
To support this the test needs some minor changes in KWin:
* Scene provides a frameRendered signal - needed for waiting on frame
* Scene and SceneQPainter are exported
* SceneQPainter provides access to it's Backend, so that we get to the
backbuffer
* ScriptedEffectLoader is exported for getting a list of all scripted
effects - (we don't want fade to manipulate the rendering)

Summary:
The clipboard sync is done by a dedicated helper binary launched by
KWin. This helper binary is forced to xcb platform to piggy-back on
Qt's implementation of the X11 clipboard. In addition it implements
the Wayland clipboard - which is much simpler. Reading the Wayland
clipboard is based on the implementation in QtWayland.
KWin internally knows the DataDeviceInterface belonging to the helper
application. Whenever an xwayland client is focussed, this DataDevice
is allowed to set the selection and KWin manually updates the current
selection in the SeatInterface. By that the sync from X11 to Wayland
is implemented. When afterwards a Wayland client is selected, it's sent
the current selection which references the X clipboard and a data
transfer can be initiated in the normal Wayland way.
For the other direction KWin sends the current selection to the helper's
DataDevice whenever an xwayland window is focused. The helper application
reads the Wayland clipboard and sets it on the X11 clipboard. Thus the
Wayland clipboard is synced to X11.
The approach used here will also be useful for implementing a clipboard
manager (aka klipper).
Currently the implementation is not yet fully completed. We need to
make sure that the helper application gets restarted in case of a crash.

For XWayland windows the window might be activated before the Wayland
Surface is set for it. Thus the keyboard focus is not passed to the
window. Only on the next activate after the window got created the
window got keyboard focus.
This change addresses this problem by emitting a signal from Toplevel
when the surface changes. The KeyboardInput listens to this signal
for the active client and updates keyboard focus again if the surface
changes. Thus keyboard focus is properly passed to XWayland windows.

The checks in Client::adjustedClientArea were a little bit too
agressive, excluding also valid setups.
This change addresses the regression by keeping the actual intended
improvements in place.
The check in Client::adjustedClientArea is now only done for the
special case of desktopArea == area. This ensures that a strut excluding
a complete screen won't affect the overall workarea.
In addition new checks are introduced in Workspace::updateClientArea.
When calculating the new sareas a check is performed whether the
intersection with the adjustedClientArea would result in the sarea
becoming empty (thus a screen being completely removed). If that's the
case the geometry is ignored to not exclude a complete screen.
Interestingly I should have noticed that something with the logic is
odd. As the test case had two commented geometries which we now get.

Summary:
The method xRenderBlendPicture created a static XRenderPicture on
first usage. To cleanup a XRenderPicture an xcb_connection_t* is needed.
As it's static the cleanup happens on exit handler and at that time Qt
already destroyed the xcb_connection_t*. With a certain chance this will
crash.
To expose the problem a Q_ASSERT(qApp) is added in the destructor of
XRenderPicture. Using xrenderBlendPicture() will hit this assert on
application exit. This is demonstrated by the added auto test.
The actual fix to the problem is moving the static variable out of
the method and introduce a global cleanup method just like the init
method. This is now called from Workspace dtor, so before application
goes down.

Summary:
The implementation was broken as it transformed the QRects into QRegions,
subtracted the geometries and took the bounding rect again. In several
setups this could result in the strut getting ignored.
This change improves the calculation of the struts by creating a QMargin
which describes the area which needs to be subtracted from a screen rect.
The QMargin is only adjusted for the edge the window borders. We can
assume that a window with a strut needs to border a screen on Wayland.
With this change we are also able to support panels between screens.
On Wayland a panel placed on the right of a left screen affects the
maximization area of the left screen, but does not affect the overall
workarea.

This new test includes everything used in events.cpp to the mocked
functionality of libinput. Only key event is implemented so far, the

The test verifies that a KeyEvent gets created and the key press/release

Summary:
The signals emitted by LibInput::Connection carry the Device for which
the input event was received. This Device is passed to the input handlers.
Custom event classes are added which extend QMouseEvent, QKeyEvent and
QWheelEvent respectively and expose the Device. The Device is only passed
around as a forward declared pointer, so even if compiled without libinput
support, it should still compile.
Event handlers which need to get access to the Device can now just cast
the event pointer to the custom class and access it. This can be used in
future to handle device specific key codes, etc.
As we don't have a proper event classes for touch events the event
handlers do not yet have access to the Device. Here the internal API
needs to be adjusted in future.

Summary:

the already created Device.

* rename AbstractBackend to Platform
* move backends/ to plugins/platforms/
* don't bind platforms to Wayland only
* provide a platform plugin for "normal" X11
* share more code between X11 and Wayland
This change moves the platform/backend from waylandServer to Application.
The init of the plugin happens directly in the Application from the
KPluginMetaData. There is no need to externally init it and set the
parent.
WaylandServer::backend() currently just delegates to
kwinApp()->platform(), the idea is to drop this method completely.
The test infrastructure is also adjusted to this change.

On build.kde.org we cannot use the breeze cursor theme. Instead we have
DMZ-White (debian package dmz-cursor-theme).
This change adjusts the PointerInput test to enforce DMZ-White and uses
SizeAllCursor instead of OpenHandCursor as that one seems to be missing
in that theme.
Hopefully with these changes the test starts to pass on build.kde.org.
Summary:
A user shouldn't be able to manually move/resize a desktop window or
a panel. So far this wasn't ensured.

Summary:
The idea behind the debugging console is to have a feature comparable
to xprop and xwininfo just for Wayland. We cannot have command line
utils as that violates the security restrictions, thus it needs to be
exposed directly in KWin.
The debugging console is invoked through DBus:
qdbus org.kde.KWin /KWin showDebugConsole
This opens a window with a tree view. The DebugConsoleModel which is
used by the tree view groups all windows into four categories:
* x11 clients (that is Workspace::clientList() and Workspace::desktopList())
* x11 unmanaged (Workspace::unmanagedList())
* wayland shell clients (WaylandServer::clients())
* wayland internal clients (KWin's own QWindows - WaylandServer::internalClients())
Each window is a child to one of the four categories. Each window itself
has all it's QProperties exposed as children.
This allows to properly inspect KWin's internal knowledge for windows and
should make it easier to investigate problems. E.g. what's a window's
geometry, what's it's window type and so on.
The debugging console is intended as a developer tool and not expected to
be used by users. That's why it's invokation is rather hidden. Due to
the fact that it's internal to KWin it results in:
* no window decoration
* stealing keyboard focus
* no way to resize, close, move from KWin side
* rendered above all other windows
There is a dedicated close button to get rid of it again. While the
console is shown it's hardly possible to interact with the system in
a normal way anymore. This is something which might be improved in
future.
At the moment the model is able to update when windows are added/removed,
but not yet when a property changes. Due to the lack of interaction with
the existing system, that's not a high priority at the moment, but can
be added in future.

A transient window should always be visible on the current screen.
This change ensures that a transient is always placed in a way that
the transient window is visible on the screen ignoring the transient
offset hint if it has to be.
Unfortunately QtWayland doesn't set the transient hint correctly:
a sub menu is a transient to the main window and not to the parent
menu resulting in quite off positioned menus, see:
https://bugreports.qt.io/browse/QTBUG-51640
Need to add client pos to the transient's position. The offset is
relative to the parent surface, but the client doesn't know about the
size of the decoration, thus KWin needs to add it.
Test creates windows and transients for it and verifies the position.
For decorated windows the position is currently broken as it does not
consider the adjusted client position.
Try to fix test on CI system. With neither a config nor the env variables
the cursor selection falls back to the default cursor theme, which might
not contain the cursors we need.
When starting effect mouse interception the current focused window
and or decoration should get a leave event. Similar when the effect mouse
interception ends the current pointer position needs to be evaluated and
a pointer enter be sent if needed.
The test case verifies that setting an override cursor during mouse
interception works and that it's also possible to change it. When
ending mouse interception the cursor image should be adjusted again.
The test shows that when mouse interception starts KWin should send
a pointer leave event to the current focused window and similar needs
to handle the stop of mouse interception.
Updating the focused pointer surface results in the cursor to change.
The CursorImage needs the current focused window to evaluate which cursor
to use, though. Thus we need to make sure that the window reflects the
current state before updating the seat.
This test case verifies that the cursor image and hot spot changes
correctly when focusing a window, changes when damaged and hides.
Test shows that when focusing a window the cursor image is not
removed, neither that unfocus sets back to fallback cursor properly.
Small regression: the command didn't get updated at all, so it was always
MouseNothing.
To prevent such a regression to sneak in again the change comes with
autotest for the action on inactive and active window.
As a Wayland server KWin does not have to emit additional key repeat
events (unlike X11). The clients are responsible for handling this based
on the provided key repeat information.
Internally KWin needs key repeat, though. E.g. the effects need key
repeat (filtering in Present Windows), window moving by keyboard needs
repeat, etc. etc.
This change introduces the internal key repeat. For each key press a
QTimer is started which gets canceled again on the key release. If the
timer fires it invoked processKey with a new KeyboardKeyAutoRepeat state.
This is handled just like a KeyPress, but states are not updated and
the QKeyEvent has autorepeat set to true.
The event filters check for the autorepeat state and filter the event
out if they are not interested in it. E.g. the filters passing the event
to the Wayland client need to filter it out.
Currently auto-repeat is bound to using libinput. This needs to be
modified. The only backend sending repeated events is X11, thus for
other backends it should be enabled.
Whether creating a timer on each key event is a good idea is something to
evaluate in future.

Experimental testing in real world showed it's just a signing issue
in this specific case. The events passed to wayland clients scroll
in correct direction.
With that all the actions are implemented just like on X11.
There are two not yet implemented differences:
* hide splash window when clicking it
* replay event on special window
Implemented in the ForwardEventFilter: before forwarding the event
to the window we check whether a modifier is pressed and perform the
wheel command.
Possible improvements: each axis event triggers the same change, there
is no adjusted scaling.
This change implements the mouse command for modifier (alt/meta) plus
click in InputRedirection so that it also works on Wayland.
Modifier plus mouse wheel is not implemented yet.
For easier code in Options a new method is added which provides the
configured modifier as a Qt::KeyboardModifier instead of a Qt::Key code.
Test case is added which simulates all variants of modifiers plus
supported mouse buttons to trigger move.
Canceling the animation in the animationEnded handler triggers a crash.
This is due to multiple lists being iterated and manipulated at the same
time.
This adds a test case which simulates the crashy situation.

So far the key handler in the InternalWindowEventFilter used the
PointerInputRedirection's internal window. This had the result that
key events were only delivered to an internal window if the window
was under the cursor.
This change tries sending the event to the latest created and visible
window. Thus e.g. with nested context menus it goes to the current
sub menu as expected. The return value of sendEvent is used to filter
out the event.
This makes QCursor::pos and QCursor::setPos function correctly. KWin
actually wouldn't need it as KWin has the KWin::Cursor replacement, but
it allows Qt internal API to have it function correctly and also the
zoom effect does use QCursor::setPos.
The mapping is slightly inspired by the mapping in QtWayland.
But the mapping in QtWayland seems wrong. E.g. there is a linux kernel
button called BTN_BACK which is not mapped to Qt::BackButton.
Anyway we are not really interested in the mapping being 100 % correct
for the case in KWin. KWin internally uses only very few mouse buttons
and all others are only relevant to figure out whether buttons are
pressed. The button code itself is passed to the seat with the native
code.
The MoveResizeWindowTest is extended by a test case to verify that
the move only ends once all mouse buttons are released. So far this
is not yet the case as KWin has an incorrect mapping of buttons to
Qt::MouseButtons.
So far KSldApp was always either in state AcquiringLock or Unlocked
during the tests. Due to a fix in WaylandServer it now can also enter
the Locked state. But this is timing related and also depends on whether
the greeter works at all. E.g. on build.kde.org the greeter fails to
start, so it never enters the Locked state.
The adjusted test now considers that the state might have changed to
Locked and expects one additional signal to be emitted.
CI system is adjusted, so that OpenGL should work. At least latest
run didn't show the EGL warnings in the lock screen test. So let's
try to enable again. It's possible that this fails horribly. If that's
the case I'll revert again.
The dontCrashGlxgearsTest is kept on QPainter as locally it crashes
on teardown (needs fixing).
The logic should not be tied to whether libinput is used. It's relevant
for all Wayland backends whether they use libinput or not.
In addition this should generate a pointer motion event, so that proper
processing can take place and we get proper pointer enter events.
The test removes the second screen while the cursor is on it. This
should warp the pointer to the center of first screen and trigger
a focus enter event.
As can be seen by the expect failures currently it's bound to libinput
and also doesn't process the event as if it were a pointer event.
If the pointer is warped the position change should be treated like
a change coming from the input device. Our normal processing should
take place.
A problem in this case is the timestamp to pass to the wayland server.
Normally our timestamps come from the backend/libinput and we don't
know the next one. As an intermediate solution we just use the last
timestamp on the seat. In future a solution could be to not use the
backend's timestamp at all, but have our own timestamp handling.
When warping a pointer through Cursor::setPos it should be processed
just like any other pointer event. It should generate enter/leave event,
create motion events, etc. This is currently not the case as the test
shows.
A new test case which ensures that when stacking order changes the
pointer focus gets re-evaluated and updated. I was positively surprised
to notice that this already works.
Noticed two other problems while writing the test case:
* warping pointer does not re-evaluate the pointer pos
* deleting a ShellSurface (client) does not destroy the ShellClient (server)
When the screen gets locked any existing sequence gets cancelled
and the focused touch surface gets reset. While screen is locked
touch events are filtered to only go to lock screen or input methods.
Test case is added for touch event during lock screen.

Instead of only making the active client the focused keyboard surface,
the method now also performs the lock screen security restriction.
Also just like udatePointerWindow the method becomes public, so that
it can be used from the LockScreenEventFilter and is connected for
lock state changes. This means as soon as the screen locks the current
focused keyboard surface will get a leave event and get an enter event
once the screen unlocks.
The auto test is adjusted to verify these new conditions.
Reviewed-By: Bhushan Shah
InputRedirection connects to lockStateChanged to udate the current
pointer window. This way we can ensure that the current pointer
surface gets reset as soon as the screen locks (c.f. the expect
fail in the autotest) and also that it restores to the surface under
the mouse once the screen is unlocked.
The relevant code was not yet lock screen aware and performed an
early exit. Part of the code was fine, e.g. findToplevel is lock
screen aware. So this change adjusts the methods for updating the
internal window and decoration to be lock screen aware, that is they
get reset. With that updatePointerWindow is also lock screen aware.
Thus the LockScreenFilter can also use updatePointerWindow just like
the normal handling and does not need to reimplement parts of it. As
it now relies on other code being correct it has an additional check
to verify that the current pointer surface is a surface which is allowed
to get events. If it isn't the events are not forwarded.

The test creates a QRasterWindow which through KWin's internal QPA
is considered an internal window. In the test methods we simulate
various pointer events (enter/leave, press/release, wheel).
First test case is whether wheel events are forwarded correctly.
From the code it seems to me like up/down is inversed. Needs manual
testing.
As this requires working decorations it's possible that this test
will fail on build.kde.org.
Interesting approach I would not have expected to work. A dummy Effect
class is created in the test and an instance is passed to
EffectsHandler's startMouseInterception. It doesn't verify whether it's
an Effect it knows or has created, so it's totally happy with the dummy.
It shows that motion and press/release are passed to the Effect when
screen is not locked and doesn't while the screen is locked.
On the CI system our tests failed due to the greeter failing to start
due to OpenGL problems. This was because we waited for a window to show
which never happened. Thus the test failed.
This change makes use of the new lockStateChanged signal to determine
when the screen gets locked/unlocked.
It's still possible that the test fails as I'm not able to reproduce
the failure condition on the CI system.
First test case is to ensure that pointer motion events trigger a
leave event on the surface the pointer is on.
The test case shows errors in the input handling.
More tests need to be added.
Trigger quick tiling by moving the window. For moving the window only
keyboard keys are used.
The test experienced some problems with the Outline triggering crashes.
To work around them the test disables the Outline by specifying an
invalid configuration.
Ensures that all Wayland objects are destroyed and the cleanup handling
is performed before tearing down the Compositor. This fixes for example
a crash if a Surface with a Shadow is still around at tear down.
WaitForFinished blocks our main thread, but Xwayland wants to talk
to Wayland and blocks as well. So let's ensure events are processed
while terminating Xwayland.
Some effects do X11 calls in their cleanup code through external
libraries (e.g. KSelectionOwner). As we cannot control that we need
to ensure the effects are unloaded prior to destroying the Xwayland
connection.
We need to destroy the ClientConnections we create. Also we need
to disconnect our Xwayland error handling before destroying it, otherwise
it would trigger the abort for crashing Xwayland.
During Compositor tear down Xwayland is already destroyed. Thus it
doesn't make sense to try to delete the support properties: either
it freezes in xcb or it crashes because the connection is null.
At the same time we also ensure that the connection internally is
reset to null. Note: the one in kwinglobals.h caches and could cause
use-after-free errors. Any tear-down code must be migrated to
kwinApp()->x11Connection().
We need to destroy the compositor after Xwayland terminated and after
the internal Wayland connection is destroyed. This means when destroying
the Workspace we may no longer destroy the Compositor at the same time.
Also we need to ensure that other tear down functionality doesn't call
into the no longer existing internal client connection.
With this change kwin doesn't crash when exiting with Wayland and/or
X11 windows still open.

Methods are no longer virtual. The only x11 specific usage in these
methods (resizeInc) is replaced by a virtual method. Default resize
increments is QSize(1,1) for AbstractClient.
Don't emit both geometryShapeChanged and geometryChanged: the one
is set up to call the other.
Also adjust tests because maximize changes triggers too many geometry
changed signals.
Method no longer virtual and only implemented in AbstractClient.
The implementaton works in a generic way nowadyas.
Added an autotest for the basic packTo behavior for packing against
a screen border. Packing towards other clients still needs adjustments
in the Placement code.
The signals operate on AbstractClient nowadays, so we can have one
implementation for both Client and ShellClient.
Only X specific connections are only done for Client.
So far only moving through useractions menu is possible and only through
cursor control (mouse events are lost).
A basic first autotest is added to validate the moving of Windows.
The problem we had was closing a glxgears through an Aurorae theme
crashed KWin inside QtQuick.
This test case simulates the sequence:
1. starts glxgears
2. wait till we have a Client for it
3. send mouse move to guessed close button position
4. send mouse press/release at that position
5. verify the window is closed
6. verify glxgears exits
With the given commit reverted this crashes, with it in place it passes.
Please note: on CI it might fail as glxgears is not yet installed. [1]
Also we cannot enforce using Aurorae from the test yet, though on
the CI system it should get picked automatically as no other deco
plugin should be installed.

If the size is the same it's basically just a window movement. That's
nothing we need to roundtrip to the client, but can adjust the geometry
change directly.
The quick tiling test is adjusted to test this together with
sendToScreen. Each window is also sent to the next screen to verify the
state doesn't change and geometry is updated.
Note: the flag for quick maximization seems to get lost in this setup.
Very basic: all screens have same size and are ordered from left to
right. It's mostly meant to allow easy test cases with multi-screen.
The quick tiling test demonstrates how it's used.
Last commit removed a setGeometry call that I thought was only used to clear an edge (which we don't want) but was in fact crucial to the next test.

This is needed to properly restore to a valid geometry after quick
maximizing. Note: this is not yet perfect, actually it should be done
after initial placing, which means we do need a manage method like
Client.
The autotest for quick tiling is extended to cover maximize changes
and cover this case.
Base test verifies the quick tile positions. No maximization or direct
state changes tested yet.
Required to have Toplevel and AbstractClient exported. Otherwise we
cannot use the SignalSpy.

Add an action type to screen edge show to allow raise/lower as well as

to know what the raise is for.

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.
With Qt 5.5 the physicalSize of a screen is broken if the X system does
not provide the XRandR extension. This caused our screen edge test to
fail on the CI system (Xvfb) due to approach window being based on the
dpi.
The problem itself is addressed for Qt in:
https://codereview.qt-project.org/126808
This change just worksaround till the change has made it into our CI
system (at which point the expected fails will break).

The test put a reference to the XCB::Window as data
to the _net_wm_transient property, not the window ID
This "works" (you get various garbage transients for
the leader in addition) as long as the window id itself
is the first item in the structure (because that is what
the test resolves to verify what it has done) bug fails
when the XCB::Window structure changes and anything
is the first item (or, btw., when the compiler feels
to re-align the structure and adds some padding...)
So let's fix the test by at least passing the proper

KWin::connection() uses the property to resolve the value instead of

It's a convenient class to encapsulate the ICCCM WM_SIZE_HINT.
Instead of exposing just the properties it provides accessors for
the interesting parts and applies sanity checks.
The test is flaky during the wait for Xephyr. Giving it more time should
hopefully make it more reliable.
The better way would be to switch to the command line argument
-displayfd pipeFd
unfortunately the Xephyr on the CI system does not yet support this
command line argument.
A new implementation of the Screens interface is added which uses XRandR
directly instead of relying on QDesktopWidget. The implementation is
provided in a new implementation file screens_xrandr.cpp.
XRandRScreens comes with a unit test. Unfortunately it's rather difficult
to provide a proper unit test against XRandR. Xvfb (which is obviously
used on the CI system) doesn't provide the XRandR extension. Also on a
"normal" developer system one would not want to just execute the test as
the results are not predictable (number of available outputs?) and the
test would mess up the setup resulting in nobody wanting to execute the
test.
As a solution to both problems the unit test starts Xephyr as a nested
X server. This allows to have at least some limited tests against XRandR.
Nevertheless there are a few things which I was not able to test:
* multiple outputs
* no output at all
The nested X Server approach makes the interaction rather complex. Qt
opens it's connection against the main X Server thus QX11Info provides
a wrong connection and also KWin::connection() which is heavily used by
xcbutils and thus all the RandR wrappers have the wrong connection. To
circumvent this problem the test is GUILESS. In case it would call into
any code using QX11Info, it would probably either runtime fail or crash.

The new test does not cover ScreenEdges completely, so far the
following areas are handled:
* creating of the edges
* reserving of edges
* trigger callback
* cursor pushback
* blocking of edges for fullscreen active clients
The default was set that the grid size for one desktop is (1, 2)
which doesn't make any sense at all - it should be (1, 1).
This most likely only affects the unit test as in production the
default layout is taken fron NETRootInfo.
This is a very interesting auto test as Screens uses both Workspace
and Client. Thus it operates in the "impossible to mock" area.
The solution is to provide mock includes in autotests and ensure that
when building the auto-test the mock header includes will be picked
first. There is now a mock class for Workspace and Client providing
just the API pieces used inside Screens.
As Screens is abstract and we cannot properly interact with
QDesktopWidget there is also a MockScreens class inheriting from Screens
and mocking the required functionality (by just operating on a list of
QRects).
The auto-test itself is only performing checks on the abstract class.
The mock class is indirectly tested by Screens calling into the virtual
methods. The test case is not yet complete, but looking quite good
already.
So far the Seat interface is provided together with pointer and
keyboard. As always touch is not yet implemented. The pointer interface
is still lacking the set cursor callback. Keyboard on the other hand is
complete.
Both Keyboard and Pointer have the concept of a focused surface and only
to the bound interface belonging to the same client as the focused
surface events are sent.
The change comes with a set of new auto tests also verifying the client
side which wasn't possible before as we couldn't fake events.
ShellSurfaceInterface is not yet completely implemented. Several parts
are still TODO, e.g. move/resize is missing, setting to maximized is
missing and also flags for fullscreen are missing.
The surface test is extended as far as possible.
The Display provides a method to create the shm pool and a
BufferInterface class is added to the server module. It is created
from the SurfaceInterface when a buffer gets attached to the surface.
The BufferInterface can be referenced and once its unreferenced it
sends a buffer release to the client and destroys itself.
For the case that the buffer is a shm buffer the BufferInterface
provides a convenience method to turn it into a QImage.
The auto test for Surface is extended by attaching buffers to the
surface and verifying that the content is correct.
As far as it's currently possible to implement. CompositorInterface is
able to create a surface and emits the created SurfaceInterface. It
does not yet support regions.
The SurfaceInterface is already more complete. It keeps track of the
double buffered states and emits signals when one of the values are
changed after the committing. It supports frame callbacks and has a
hook to mark the frame as rendered.
What's still missing are the regions (as it's not implemented in
CompositorInterface) and attaching the buffer as we do not yet support
creating shm buffers and pools.
The client side test is changed to use our own server and extended to
test damage and frame callback. The test needs to be extended for scale
and transform, but that is still missing in the client side
implementation.
So far this new module contains:
* Display
* OutputInterface
Display manages the server socket and server event loop. In general it's
the entry point to any part of the server.
OutputInterface is the abstraction for the wl_output interface on server
side. An OutputInterface is created through the Display.
The auto tests for ConnectionThread and Output are adjusted to use the
internal server instead of starting Weston. Especially the Output test
could be extended to test much more as we have absolute control over
the server now.
Technically the Surface itself does not have a size, it's the
ShellSurface or the size of the FullScreenShell's Output. But it
simplifies a lot if we keep track of the size in the Surface as that
way we can hide the fact which kind of Shell is used.
The user of the Surface must connect either the FullscreenShell's
Output or the ShellSurface to set the size on the Surface.
The fullscreen shell is only provided with at least Weston 1.5.
It should be checked on runtime, but that's difficult as Weston doesn't
fail if it cannot find the shell.so. So we disable it based on the
assumption that if Wayland library is not 1.5 the Weston is also not 1.5.
A Surface class is split out which holds a wl_surface and supports
attaching a buffer, setting the damage and emitting a signal when the
frame callback got called.
It doesn't come with a unit test yet as it first needs the ShmPool
and Buffer properly split out to easily set it up.
New classes Shell and ShellSurface are created. Both are in shell.[h|cpp]
to indicate their close relationship with the Shell having to create the
ShellSurface.
WaylandBackend is adjusted to hold a Shell* and ShellSurface* instead of
the lower level structs. This also required adjustements to the creation
of the Backend as it now doesn't set a default size any more. Thus the
backendReady signal may not be emitted before the initial configure
event arrived. This also makes it easier to support either the fullscreen
shell or wl_shell at the same time.
Of course a unit test is added for the two new classes. This needs to
be extended once we have more control over the mock Wayland server.
At the same time adding an autotest for the Output, moving the listener
into the Output class and providing enums for Subpixel and Transform.
KWin now requires wl_ouput interface version 2 as that allows us to emit
the changed signal in a better way.
The unit test is not yet capable of testing everything, we need a mock
Wayland server which is more flexible.
