If the Xwayland executable can't be found, the whole session will die
because a criticalError() signal will be emitted.
This change replaces the criticalError() signal with a less severe
signal.
If the errorOccurred() signal has been emitted during the startup
sequence, kwin won't die and will just continue with spawning the
session process.
After splitting out the server part of KWayland into a separate repo,
all non-core protocol wrappers in KWayland::Client had become obsolete
and using them in new projects is highly discouraged.
QPointer is a really useful way to store a pointer over time.
It doesn't make have any value as a return value used by a short-lived
method.
There isn't a good copy constructor, it's effectively the same as
creating a new QWeakPointer reference that has to be cleaned up.
Testing if something is null is still the same. A new QPointer can be
made by the caller if it actually is needed.
Input handling is a very hot path called many times a frame, so it's
important to keep this light. focus() and at() are called a lot which
added up to slightly over 1% of CPU time when moving the mouse about.
The layer-shell protocol allows wayland clients to create surfaces that
can be used for building desktop environment components such as panels,
notifications, etc.
The support for the plasma-shell protocol will be dropped once plasma in

in XdgSurfaceClient setFrameGeometry is async,
so we can't rely on it having the final value immediately.

If the Xwayland process has crashed due to some bug, the user should
still be able to start applications in Xwayland mode. There is no reason
to restart the whole session just to be able to launch some application
that doesn't have native support for Wayland.
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.
In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.
If the Xwayland process crashes, it will bring down the entire session
together with itself. Obviously, we don't want that. At least, Wayland
clients should survive the crash.
This change refactors relevant X11 parts to handle Xwayland crashes in a
less fatal way.
In order to handle Xwayland crashes better, a pair of start() and stop()
methods had been introduced in the Xwayland class to allow starting and
stopping the Xwayland process at any moment.
If we detect that the Xwayland process has crashed, we will immediately
stop the Xwayland server, which in its turn will deactivate the socket
notifier and destroy all connected X11 clients. Unfortunately, a couple
of subtle changes in X11Client::releaseWindow() and Unmanaged::release()
had to be made to ensure that we are left with a valid state after the
Xwayland server has been stopped.
Currently, the trend is to get the coordinates of the hotspot and map it
to the device independent pixels at the call site.
This change makes the KXcursorSprite return the coordinates of the hotspot
in the device independent pixels to reduce the amount of duplicated code.
In rare cases, Workspace::restoreFocus() may fail, for example when the
most recently activated client is about to be destroyed or unmapped.
If it happens that we cannot restore the focus, then mark the window in
FocusIn event as active.
CCBUG: 424223
If AbstractClient::setFrameGeometry() is called from a slot connected
directly to the frameGeometryChanged() signal, then is there a good
chance that kwin will fall into an infinite recursion. However, that's
the case with only X11 and internal clients.
The root cause of the infinite recursion is that both X11Client and
InternalClient compare the new geometry against the geometry before
update blocking. In order to fix the bug, we simply need to ensure that
updateGeometryBeforeUpdateBlocking() has been called before we start
emitting the frameGeometryChanged() signal.
Furthermore, a couple of tests were added to ensure that we won't hit
this subtle bug again.
Unfortunately, a0c4a8e766 has a major bug
where clients that track focus events may get confused by focusToNull().
One such a notable example is Dota 2. It tracks the focus events to
minimize itself after the keyboard focus has been lost as well stop
playing music while it's in background. So, when we call focusToNull(),
Dota 2 will receive a corresponding FocusOut event and ask the window
manager to minimize it. It doesn't really matter that the FocusOut
event is going to be followed by a FocusIn event because when a window
is minimized, kwin will activate the next one in the focus chain.
Since those issues can't be fixed from the window manager's side, this
patch partially reverts a0c4a leaving only the autotest.
BUG: 424223
FIXED-IN: 5.19.4
Implemented for Global, Virtual Desktop and Application layout policies.

Layout saving/restoring happens on Session save/load.
Covered by unit tests
Currently, we update the input transformation matrix for the focused
pointer surface only when the frameGeometryChanged() signal is emitted.
However, since the input transformation matrix is computed based on the
current position of the upper left corner of the main surface, it is
wrong to do so because the frame geometry is a logical geometry that
doesn't have any direct relationship with the buffer geometry, i.e. the
rect on the screen occupied by the main surface.
If the input transformation matrix gets out of sync, user may notice
that pointer events are "shifted."
This change introduces a new signal that's emitted when the input
transformation matrix has been changed. Input related components in kwin
can connect to it to keep a copy of the input transformation matrix in
SeatInterface in sync. Under the hood, the new signal is just an alias
for the bufferGeometryChanged() signal.
Currently, the test passes because the activities controller doesn't
have enough time to fetch all activities. So, the test client won't be
placed on the current activity.
Since the Workspace is now created before starting the Xwayland, we now
spin the event loop, which allows the activities controller to fetch the
list of all activities and so the test client will be placed on the
current activity, i.e. client->isOnAllActivities() will no longer return
true.
This change fixes wrong assumptions in the test and makes it robust.
Sub-classes of the AbstractClient class need a valid instance of the
Workspace class to function as desired. We should not create xdg-shell
clients until the workspace is created.
The new signal is emitted when the Application has fully been initialized.
It allows us to change the startup sequence, for example create workspace
before starting the Xwayland server, without making any adjustments in our
test suit.
Don't give the InputConfig a separate config instance. I've seen it
being changed after having initialized the xkb instance which would
break the shared instance.
Using a simple config rather than reading the configuration from
the actual code-path shouldn't make a difference as a test it will be
using ~/.qttest which should be cleaned upp
Screens are set during init, to do so at cleanup doesn't bring a lot.
It leads to a potential awkward raciness with xwayland failing the test,
whilst doing something that isn't part of what we're testing here or
likely to happen in real life.
We were calling it from tests that were not running a KWin::Application
and not even including the symbols from main.cpp and main.h. The only
reason they linked was that it was static_casting up the QCoreApplication.
Depending on the current focus stealing prevention level, it's possible
for kwin to call XSetInputFocus() on a window that already has the input
focus. In which case, we won't receive the corresponding FocusIn event
and the client will remain inactive from kwin's perspective even though
it isn't.
In order to work around this issue, we can move the input focus to the
null window. By doing so, it's guaranteed that we're going to receive
the matching FocusIn event for the client.
This commit indirectly fixes a bug where fullscreen games are displayed
below panels.
We send two async actions via another process
We do a wait for one
We check that we received two events
This is racey. QTRY_COMPARE can allow both events to arrive separately.
Currently in order to load an Xcursor theme, kwin uses libwayland api,
which looks really awkward because of the way how the compositor talks
to itself via the internal connection.
The main motivation behind this change is to limit the usage of kwayland
client api in kwin.
Currently the only way for a uuser to invoke corner-tiling is to
manually set shortcuts for them. This patch adds another option: invoke
the existing shortcuts for edge tiling in a combined manner in quick
succession.
For example, hitting Meta+Left and then Meta+Up within a one-second
period will tile the active window into the top left corner. In practice
you hold down the Meta key and then press Left then Up (or Up and then
Left), and I think it feels very natural. Linux Mint's window manager
has this feature and I always missed it when I left Mint for the KDE
world.
Autotests for existing tiling shortcuts are adjusted to not break, and
additional tests for the new tiling options are added.
There are several ways to handle unmapping of a wl_surface. The first
one is to destroy the associated AbstractClient instance. The second one
is to transition the AbstractClient in a special state.
The problem with the second approach is that it makes animations such as
fade out more difficult to handle since effects in kwin are geared more
towards the first approach (destroying AbstractClient).
Summary:
This change splits the XdgShellClient class to better match existing
abstractions in the xdg-shell protocol and fix a few issues related to
sending configure events.
In the new client classes, configure events are handled differently.
Instead of blocking configure events, we try to send them as late as
possible. Delaying configure events will let us merge changeMaximize()
for X11 clients and Wayland clients and it also fixes the bug where
we don't send the final configure event when user has finished resizing
a window.
Given that configure events are not sent immediately, XdgSurfaceClient
keeps the last requested frame geometry and the last requested client
geometry.
This patch doesn't intend to fix all issues in kwin's implementation of
the xdg-shell protocol. For example, we still handle surface unmapping
very poorly.
Test Plan: Tests pass.

While Alt can be changed to Meta in KWin's settings, Alt + Left Click shortcuts often cannot be customized in apps. Rather than making every user who runs into this problem change their settings, we should change our default settings to improve KWin's default usability. The fact that Alt + Left Click to move windows is older does not matter. We are trying to use Meta for global/shell shortcuts anyway.

Summary:
Currently, there are a couple of issues with sizeForClientSize(). First
of all, we have a method called clientSizeToFrameSize() which does similar
thing except applying geometry constraints and checking window rules. The
other issue is that sizeForClientSize() is doing a bit too much, it checks
window rules, it applies a bunch of geometry constrains. Sometimes it
does not perform conversion between client sizes and frame sizes!
This change attempts to address those issues by replacing sizeForClientSize
with two similar methods and changing semantics of some methods of the
X11Client class.
The most significant difference between sizeForClientSize() and the new
methods is that neither constrainClientSize() nor constrainFrameSize()
check window rules. This is up to users of those methods. In many places,
we don't have to check window rules because we check isResizable(),
which returns false if the frame size is enforced by a window rule.

Summary:
Currently we have two signals that are emitted when the Toplevel's geometry
changes - geometryShapeChanged() and geometryChanged(). The former signal
is used primarily to invalidate cached window quads and the latter is
sort of emitted when the frame geometry changes. But it's not that easy. We
have a bunch of connects that link those signals together...
The worst part about all of this is that the window quads cache gets
invalidated every time a geometry update occurs, for example when user
moves a window around on the screen.
This change introduces a new signal and deprecates the existing geometryChanged
signal. frameGeometryChanged is similar to geometryChanged except that it is
emitted when an _actual_ geometry change has occurred.
We do still emit geometryShapeChanged signal. However, in long term, we
need to get rid of this signal or come up with something that makes sense
and doesn't require us to waste computational resources.

Summary:
Qt has its own thing where a type might also have corresponding list
alias, e.g. QObject and QObjectList, QWidget and QWidgetList. I don't
know why Qt does that, maybe for some historical reasons, but what
matters is that we copy this pattern here in KWin. While this pattern
might be useful with some long list types, for example
QList<QWeakPointer<TabBoxClient>> TabBoxClientList
in general, it causes more harm than good. For example, we've got two
new client types, do we need corresponding list typedefs for them? If
no, why do we have ClientList and so on?
Another problem with these typedefs is that you need to include utils.h
header in order to use them. A better way to handle such things is to
just forward declare a client class (if that's possible) and use it
directly with QList or QVector. This way translation units don't get
"bloated" with utils.h stuff for no apparent reason.
So, in order to make code more consistent and easier to follow, this
change drops some of our custom typedefs. Namely ConstClientList,
ClientList, DeletedList, UnmanagedList, ToplevelList, and GroupList.

A better approach to deal with internal clients is to let our QPA use
kwin core api directly. This way we can eliminate unnecessary roundtrips
as well make geometry handling much easier and comprehensible.
The last missing piece is shadows. Both Plasma::Dialog and Breeze widget

drop-shadows at the moment, I don't consider it to be a blocker. We can

Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer

Reviewing such changes has been a bit frustrating for me (so selfish!)

This change switches doxygen comment style in KWin to a more traditional

Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.
The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.
Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.
A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!
The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.
The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.
Test Plan: Compiles.

Summary:
Currently, the Night Color manager supports three operation modes:
* Automatic: in this mode, screen color temperature is computed based on
the current position of the Sun. In order to calculate sunrise & sunset
times, the manager needs coordinates of the user, which are provided by
Plasma;
* Location: this mode is very similar to the Automatic, except one minor
detail: user needs to provide his/her/their location. This mode can be
very useful if coordinates provided by Plasma are incorrect;
* Timings: unfortunately we can't compute timings of the Sun for people
living near Earth poles. This mode allows the user to specify timings of
sunrise and sunset as well the transition time.
This change introduces another mode, called Constant. With this mode the
screen color temperature is constant throughout the day. The new mode
can be useful for people wishing constant screen color temperature or
just for people living near Earth's North or South poles.

Since d51b8dc093 the test fails on CI, apparently because we test with
Breeze default settings, which is no borders now and we can move a bit into
the window geometry and still be on the border if borders exist, otherwise
not.
For now fix it by checking if there are borders or not and then test
accordingly. But long-term we should test both cases and besides not rely on
external decorations for our test, instead use a fake specific for our
integration testing.
Summary:
The size passed to an XDG shell configure request should match the
window size of the given window, we don't want to include the size of
any shadows that may be drawn by the client.
Kwin has the same concept of geometry for both window management, input
and rendering.
In order to approach this in a way that does not risk any regressions
with kwin's current structure AbstractClient::geometry remains the
canonical source and we handle the window within that internally within
ShellClient treating the windowGeometry as a set of margins from this.
This is part of a much bigger task (T10867). This patch addresses
windows growing when starting a drag based resize.

By blocking sending configure events we will have flushed the correct

On Wayland we cannot switch from OpenGL to QPainter compositor as this
would break any running OpenGL application. KWin registers it's
EGLDisplay to Wayland and without OpenGL this doesn't make sense any
more. We are not able to render OpenGL buffers in the QPainter
compositor.
While it's theoretically possible to switch from QPainter to OpenGL it
doesn't make any sense for the same reason. Any running OpenGL
application would be using llvmpipe and could not be switched to proper
OpenGL.
This change stores the selected compositing type in Platform and the
implementations can use it to restrict the supported compositors. On X11
we don't need this, all other Platforms implement the restriction. Thus
it's no longer possible to switch the backends at runtime.

Summary:
Most of the functionality which is special to internal clients is moved
from ShellClient to InternalClient. As KWin's qpa is still bound to the
Wayland protocol InternalClient inherits from ShellClient. Due to that
some aspects in ShellClient are "weird". ShellClient still detects
whether it's an internal client and uses the variable m_internal to
capture the state. This is required as we cannot use the isInternal
method. Most of m_internal usage is in init which is called from
constructor of ShellClient. Thus it's not possible to call into virtual
methods of InternalClient.
Also some of the code is duplicated and some methods are temporarily
marked as virtual.
The next step will be to remove ShmBuffer for internal windows which
should decouple the two implementations further with the long term goal
of having InternalClient inherit AbstractClient directly.

Summary:
In this patch an infrastructure is created to represent generic X selections
in a Wayland session and use them for data transfers between Xwayland windows
and Wayland native clients.
The central manager is the DataBridge class, in which Selection objects can be
created. This is hard-coded and such a Selection object persists until the end
of the session, so no arbitrary selections can be created on the fly. For now
the X Clipboard selection is supported, whose corresponding mechanism in the
Wayland protocol is just called Selection.
A Selection object listens for selection owner changes on the X side and for
similar events into the Wayland server interfaces. If a data provider is
available a selection source object is created by the Selection object. In case
data is requested on the other side, a data transfer is initialized by creating
a Transfer object. A Selection keeps track of all transfers and makes sure that
they are destroyed when they are finished or in case they idle because of
misbehaving clients.
The Clipboard class translates the X Clipboard via a proxy window. Selection
changes on the Wayland side are listened to through a new signal on the active
KWayland seat interface.
The previously used X clipboard syncer helper is disabled. The clipboard sync
autotest is changed to the new mechanism.

Summary:
KWindowSystem provides a plugin interface to have platform specific
implementations. So far KWin relied on the implementation in
KWayland-integration repository.
This is something I find unsuited, for the following reasons:
* any test in KWin for functionality set through the plugin would fail
* it's not clear what's going on where
* in worst case some code could deadlock
* KWin shouldn't use KWindowSystem and only a small subset is allowed
to be used
The last point needs some further explanation. KWin internally does not
and cannot use KWindowSystem. KWindowSystem (especially KWindowInfo) is
exposing information which KWin sets. It's more than weird if KWin asks
KWindowSystem for the state of a window it set itself. On X11 it's just
slow, on Wayland it can result in roundtrips to KWin itself which is
dangerous.
But due to using Plasma components we have a few areas where we use
KWindowSystem. E.g. a Plasma::Dialog sets a window type, the slide in
direction, blur and background contrast. This we want to support and
need to support. Other API elements we do not want, like for examples
the available windows. KWin internal windows either have direct access
to KWin or a scripting interface exposed providing (limited) access -
there is just no need to have this in KWindowSystem.
To make it more clear what KWin supports as API of KWindowSystem for
internal windows this change implements a stripped down version of the
kwayland-integration plugin. The main difference is that it does not use
KWayland at all, but a QWindow internal side channel.
To support this EffectWindow provides an accessor for internalWindow and
the three already mentioned effects are adjusted to read from the
internal QWindow and it's dynamic properties.
This change is a first step for a further refactoring. I plan to split
the internal window out of ShellClient into a dedicated class. I think
there are nowadays too many special cases. If it moves out there is the
question whether we really want to use Wayland for the internal windows
or whether this is just historic ballast (after all we used to use
qwayland for that in the beginning).
As the change could introduce regressions I'm targetting 5.16.
Test Plan:
new test case for window type, manual testing using Alt+Tab
for the effects integration. Sliding popups, blur and contrast worked fine.

Summary:
So far we didn't try to do high DPI on kwin internal windows, such as
the user context menu and tab bars and whatever.
Due to wayland scaling they were the correct phyiscal size but upscaled.
This patch fixes our QPA to enable Qt's high-dpi support.
BUG: 402853
Note icons are still low res. This is because the global
QGuiApplication::devicePixelRatio which is the max of all connected
screens is static for the duration of the app. QIcon uses this when
determining the DPR to use. This will require a Qt change.
Test Plan:
Ran at 2x on my normal DPI screen (as that's easier to see anything)
* User action menu is high DPI
* Window deco tooltips are still fine
* Tab switcher is high DPI
* Overlay in present windows Desktop grid are still ok

Summary:
The SceneOpenGLES test was starting to randomly crash on my system. On
investigation I observed that there was a graphics reset ("Attempting to
reset compositing.") which triggered a delayed restart of the
compositor. This even was only processed while waiting for XWayland to
terminate. Which resulted in a crash in KWin::getXServerVersion as the
xcb connection broke.
It makes no sense to setup the compositor again during application
shutdown. Thus the dtors set a flag that they are terminating the
application and Compositor::setup is checking for it.

Summary:
So far transients were placed anywhere on the screen. This behavior was
inspired from X11 where context menus were able to overlap any other
window and use the complete screen area. On X11 context menus and
similar windows are override redirect and thus above all windows managed
by KWin.
On Wayland, though, context menus and similar and windows just like any
other window and thus follow stacking constraints like the parent
window. A context menu is stacked just above it's parent and is
(normally) below any panels. This resulted in problems that context menu
are stacked behind the panel with unreachable options.
This change changes the placement for transients to use the
PlacementArea instead of a screen geometry. Thus the transient does not
render behind the panel. Only in case of a fullscreen the struts are
ignored.

The dialog invoked through user actions menu takes the internal uuid as

from KWin instead of using X11.
This allows to enable the system for Wayland windows.
In order to replace the usage of ClientMachine in the rules dialog the
dbus interface is extended by a value whether the window is on the
localhost. This is exposed through a virtual method on toplevel which is
overridden in ShellClient and there always returning true.

When looking at the test results on build.kde.org we see this is the
test which fails most often and it's always at the same line of code.
So I just had a look with the thought: "what's special about this code,
why could it fail?"
Looking at it we start an external process which is supposed to connect
to KWin. We wait for the process to start and then wait for the shell
client added. This assumes that at the time we handle the wait for
started the connection of the window has not happened yet.
Waiting for the process in a blocking way, might make the process fail
to connect to the Wayland session, so this is changed to not block and
instead use a signal.

This dbus method is intended to be used by the kwin rules dialog. KWin
can pass the internal id to the rules dialog through a command line
argument (or similar way) and the dialog can query the information
through the dbus call for the provided id. Thus it's possible to
implement one way to query the information which works on both X11 and
Wayland without any windowing system specific functionality.

wanted and interfere with the application. E.g. one does not want Alt+F4
to close the window, that would render the system unusable.

event filters and spies:
* global shortcuts
* modifier only shortcuts
* terminate session
* virtual terminal switching
* screen edges

For supporting Wayland windows in the kwin_rules_dialog we need a way to
pass a window id for Wayland windows to the dialog. This id needs to be
sent to the dbus interface to query window information just like the
interactive query. For Wayland windows we don't really have a window id
and it would require to also pass the windowing system to
kwin_rules_dialog and back through the dbus interface.
To not complicate things this change introduces a windowing system
independent id based on UUID. This could in future also be used
internally for areas where it's window id based and used in both
windowing systems.

Summary:
Consider current implementation of the Squash effect: if a window was
minimized, an animation will be started; if the window is unminimized
and the animation is still active (that can happen when user clicks on
app's icon really fast), the animation will be stopped and a new one will
be created. Such behavior can lead to rapid jumps in the observed
"animation".
A better approach would be first try to **reverse** the already active
animation, and if that attempt wasn't successful, start a new animation.
This patch introduces a new function to the scripted effects API that
lets JavaScript effects to control direction of animations. The
prototype of the function looks as follows:
redirect(<animation id(s)>, <direction>, [<termination policy>])
the first argument is an animation id or a list of animation ids, the
second argument specifies the new direction of the animation or
animations if a list of ids was passed as the first argument. The
third argument specifies whether the animation(s) should be terminated
when it(they) reaches the source position, currently it's relevant only
for animations that are created with set() function. The termination
policy argument is optional, by default it's Effect.TerminateAtSource.
We can use this function to fix issues with rapid jumps in the Squash
effect. Also, redirect() lets us to write effects for simple animations
in slightly different style: first, we have to start the main animation
(e.g. for the Dialog Parent effect, it would be dimming of main windows)
and then change direction of the animation depending on external events,
e.g. when the Desktop Cube effect is activated.
