Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.
This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.
We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
A recent patch made it possible to restart KWin when it crashes, this
opens the possibility to do it for development purposes. So far it could
be done using `killall -9 kwin_wayland`. This patch embraces this
functionality under --replace so it's a bit more documented and under
its own semantics.
It is done by returning the process with 133 exit code and picking that
code specifically as a wish to restart.
Add the activities info to the list of properties provided by
the `queryWindowInfo()` dBus method, and suggest them to the
user when inspecting a given window.
An empty activity list means "All Activities" (null UUID)
Also get the null UUID value instead of having it hardcoded.
The scripting api is not suitable for implementing all features that
should not be implemented in libkwin. For example, the krunner
integration or screencasting are the things that don't belong to be
compiled right into kwin and yet we don't have any other choice.
This change introduces a quick and dirty plugin infrastructure that
can be used to implement things such as colord integration, krunner
integration, etc.
Currently, the method `createErrorReply()` with empty strings
errors out and the client gets no answer:
```
QDBusConnection: error: could not send error message to service "":
Error name cannot be empty
```
Simple test:
qdbus org.kde.KWin /KWin org.kde.KWin.showDebugConsole
qdbus org.kde.KWin /KWin org.kde.KWin.queryWindowInfo
Error name uses D-Bus Interface-like notation as suggested in
https://doc.qt.io/qt-5/qdbuserror.html#name
CCBUG: 340477
This change replaces the remaining usages of the old connect syntax with
the new connect syntax.
Unfortunately, there are still places where we have to use SIGNAL() and
SLOT() macros, for example the stuff that deals with d-bus business.
Clazy was used to create this change. There were a few cases that needed
manual intervention, the majority of those cases were about resolving
ambiguity caused by overloaded signals.
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.
Summary:
Compositor::hasScene() is redundant. Depending on use case, it can be
replaced by checking either m_state or Compositor::scene().

Summary:
This patch is a first take at splitting up of the Compositor class into
Wayland and X11 child classes.
In this first patch we mostly deal with setup and teardown procedures.
A future goal is to further differentiate the compositing part itself too.

This removes the restart function of the Compositor class and renames the
internal reinitialize function.
Instead of the restart function reinitialize can be called. Reading again
the settings in this case is fine, since it is done rarely. This reduces
the code complexity.

Summary:
The dialog invoked through user actions menu takes the internal uuid as
command line argument which allows to query the required information
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.
Test Plan: Run a nested Wayland and opened the dialog on a wayland window

Summary:
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.

Summary:
implement virtual desktop support for Wayland.
use the new virtual desktop protocol from D12820
The VirtualDesktopManager class needed some big change in order
to accomodate it, which is where most changes are.
Other than that, it's mostly connections to wire up
VirtualDesktopsManager and VirtualDesktopsManagement(the wayland protocol impl)
Depends on D12820
Other notable detail, is the client visibility updated to reflect the presence
of the client in the plasmavirtualdesktop.
(and the unSetDesktop concept)

Summary:
This call is added for the window rules kcm which has a detect
functionality. As that detect functionality cannot query any Wayland
windows we need to have some functionality in KWin core. Furthermore
this allows to simplify the code in the kcm as all the custom X11
interaction can be removed. KWin internally has the functionality to
find a window at a given position.
From a security perspective adding this dbus method is fine as the user
stays in control of the functionality. It requires active click to
select a window.
The new dbus call is already used in the rules kcm replacing the
X11 based detect functionality. That a detect is now able to get
information for both X11 and Wayland windows. So far only X11 windows
on X11 were supported. So this fills an important gap in the Wayland
offerings. It should now be possible to create rules for Wayland
windows (though may not be fully functional).
Test Plan: Run the kwin_rules_dialog and it detected the window correctly

Summary:
KWin's DBusInterface announces the service name on an X11 root window
property. For this it requires a runtime dependency on X11. If we would
try to start kwin_wayland without XWayland support this would result in
a crash.
This change turns the dependency into an optional one by checking
whether the KWin::Application has support for X11 and registers a
connection to announce the property as soon as a connection is
established. Thus it even supports the restart of XWayland now.

On Wayland compositing is required. It doesn't make any sense to offer
the user to disable the compositor or to allow windows to block
compositing.
The Compositor DBus interface gains a new property whether the platform
requires compositing. This is queried by the compositing kcm and based
on that the two mentioned options get hidden and not stored to config
file.

Summary:
CompositingPrefs is only relevant for X11 standalone. It had some
"hacks" to make it not block Compositing on Wayland. Thus it was in
its current form not really useful.
Now all the functionality is provided through Platform with a default
implementation which is sensible for Wayland platforms.
The X11 standalone platform implements the new methods with the
Wayland checks removed.
In addition all calls to CompositingPrefs now go through the platform
directly and CompositingPrefs is completely dropped.

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.

So far it was bound to whether we build for GLES. But this is
semantically wrong. It might be possible that even on desktop gl
epoxy is built without GLX support, thus we need to reflect this.
This change ensures that epoxy/glx.h is only included if available,
that relevant code is bound to it and that checks are in place to
enforce EGL if not build with glx support.
In addtion the glxbackend.cpp is now only included in the build set
if available.
It doesn't make much sense any more as we do no longer link EGL since the
switch to epoxy. And epoxy pulls it in at runtime if needed.
Even more on Wayland it's just plain stupid to have EGL disabled. So
removing the option just simplifies our code base without any
disadvantages.

This is a temporary workaround for bug 349992 which causes freezes
during startup as kwin and kamd dead lock each other on DBus.
To workaround we don't call Activities::create and check in every

As a result kwin_wayland now starts pretty fast.

All activities related code moves into new singleton class Activities.
This class gets only included into the build if the build option is
enabled which means there are less ifdefs all over the code and it also
handles better the moc doesn't like ifdef case.
The class holds the list of open and all activites, the current and the
previous activity and the KActivities::Controller. It also emits the
signals for any activities related changes.
Workspace still contains some activities related code. That is the
adjustment on change of current activity. Nevertheless the code looks
much cleaner now and does not contain the confusing naming conflict with
takeActivity() which existed before.
In all the places where Activities got used the code got adjusted and
quite often the ifdef got added with a fallback for the disabled case.
The hack used to be used to hide windows before they get embedded into
another window. This has been wrong on multiple levels:
1. it does not belong into a window manager - the window should take care
of this by itself
2. Window title is not a proper way to identify windows
3. Using D-Bus to inform an X11 window manager about windows which should
not get managed is rather strange
4. The hack only works with KWin, but not with any other X Window Manager
5. Windows identified with this hack still appear in Alt+Tab, that is
they are managed after all. Only a flicker is suppressed
6. Such windows are shown in the taskbar which nicely illustrates how
wrong a D-Bus call to the window manager is
That the hack has been introduced for Java Applets in KHTML also shows
that this is wrong. Why does Gecko and WebKit not need such a hack? Why
is KHTML tied so closely to X11 and KWin? Having a hack for a technology
which is obsoleted (Java Applets) and shouldn't be used due to security
issues is another reason to no longer support this hack. This usage has
been removed from KHTML as of 67939b1 of kdelibs git repo.

The ownership for virtual desktops is moved from Workspace into a new
VirtualDesktopManager. The manager is responsible for providing the count
of virtual desktops and keeping track of the currently used virtual
desktop.
All methods related to moving between desktops are also moved from
Workspace to the new manager, though all methods related to Clients on
Virtual Desktops remain in Workspace for the time being. This is to have
the new manager as independent from KWin core as possible.
An rather important change for the handling of virtual desktops is that
the count and the id of a desktop is now an unsinged integer instead of
an integer. The reason for that is that we cannot have a negative count
of desktops as well as it is not possible to be on a desktop with a
negative identifier.
In that regard it is important to remember that a Client can be on a
desktop with a negative identifier. The special value for a Client being
on all desktops is handled by using -1 as a desktop. For the time being
this is not adjusted but instead of comparing the virtual desktop ids one
should prefer to use the convenient methods like isOnDesktop and
isOnAllDesktops. This would allow in future to internally change the
representation for on all desktops.
It is more Placement related and does not really fit into geometry given
that it only calls methods on Placement. It probably only was inside
Workspace due to being part of the DBus interface. The DBus methods are
used by external components so it needs to stay.
The DBus Wrapper is now calling the methods on the singleton Placement
directly, so no need in Workspace anymore.
It is not used anywhere inside KWin at all and the DBus method is not
used anywhere inside KDE's repositories (according to lxr). Because of
that marked as deprecated and going to die with Qt 5.

Two new interfaces are introduced:
* org.kde.kwin.Compositing
* org.kde.kwin.Effects
The Compositing interface is generated from scriptable elements on the
KWin::Compositor class and the Compositor is exported as /Compositor.
It provides the general Compositing related D-Bus methods like whether
the compositor is active and toggling and so on.
The Effects interface is generated from scriptable elements on the
KWin::EffectsHandlerImpl class and the instance is exported as /Effects.
It provides all the effects related D-Bus methods like loading an effect
or the list of all effects.
This removes the need to have all these methods provided on the global
org.kde.KWin interface. For backwards compatibility they are kept, but
no longer provided by the Workspace class. Instead a new DBusInterface
is generated which wrapps the calls and delegates it to one of our three
related Singleton objects:
* Workspace
* Compositor
* EffectsHandlerImpl
