Due to being a compositor, kwin has to conform to some certain
interfaces. It means a lot of virtual functions and function tables to
integrate with C APIs. Naturally, we not always want to use every
argument in such functions.
Since we get -Wunused-parameter from -Wall, we have to plumb those
unused arguments in order to suppress compiler warnings at the moment.
However, I don't think that extra work is worth it. We cannot change or
alter prototypes in any way to fix the warning the desired way. Q_UNUSED
and similar macros are not good indicators of whether an argument is
used too, we tend to overlook putting or removing those macros. I've
also noticed that Q_UNUSED are not used to guide us with the removal no
longer needed parameters.
Therefore, I think it's worth adding -Wno-unused-parameter compiler
option to stop the compiler producing warnings about unused parameters.
It changes nothing except that we don't need to put Q_UNUSED anymore,
which can be really cumbersome sometimes. Note that it doesn't affect
unused variables, you'll still get a -Wunused-variable compiler warning
if a variable is unused.
There are a few benefits to using smart pointers from the standard library:
- std::unique_ptr has move semantics. With move semantics, transfer of ownership
can be properly expressed
- std::shared_ptr is more efficient than QSharedPointer
- more developers are used to them, making contributions for newcomers easier
We're also already using a mix of both; because Qt shared pointers provide
no benefits, porting to standard smart pointers improves consistency in
the code base. Because of that, this commit ports most of the uses of QSharedPointer
to std::shared_ptr, and some uses of QScopedPointer to std::unique_ptr
This makes KWin switch to in-tree copy of KWaylandServer codebase.
KWaylandServer namespace has been left as is. It will be addressed later
by renaming classes in order to fit in the KWin namespace.
The plasma window management protocol is intended to be used by
plasmashell. Since kwin and plasmashell have the same release cycle, we
know that the legacy virtual desktop stuff is unused so it can be
dropped to simplify code.
Currently, plasma window model test fails because the null icon is
received after executing the main body of the test.
FAIL! : PlasmaWindowModelTest::testVirtualDesktops() '!dataChangedSpy.wait(100)' returned FALSE. ()
Loc: [/data/projects/src/kwayland-server/autotests/client/test_plasma_window_model.cpp(583)]
We can fix the test by waiting for the iconChanged signal to be emitted,
but we will need to wait in all tests too. Furthermore, it doesn't make a
lot of sense to wait for an icon that was never set.
This change makes the compositor send an icon only if there is one.
It's a behavioral change, but it shouldn't regress anything because kwin
always sets icons via the plasma window management protocol even for apps
that have no valid app id.
It also makes the api of the PlasmaWindowInterface class more intuitive.
PlasmaWindowInterface is a "Server-managed multicasting resources". We
no longer need our wrapper to outlive objects so we can tidy that up.
It's weird to have a method call to an object delete the object, so
memory management is moved to the caller to be consistent.
s_version is used only to initialize a global so there is no point for
storing protocol version in a static member field and use funky syntax
in the cpp file to initialize it. This change also simplifies the code.
Summary:
Remove unused variables and members.
We were often storing the q of classes without ever needing them. I'd
just do it when it's useful. We do it in the private class so it can
always be added, removes boilerplate code.
Don't use std::move when returning temporary QImage. The compiler is
smart enough to know to do it but produces the warning "moving a
temporary object prevents copy elision".
Remove unused lambda captured variables.

Summary:
Implement the virtual desktop protocol discussed in
T4457 xml protocol, client and server part.
The PlasmaVirtualDesktopManagement interface manages the desktops
instantiation and layout, each desktop is a PlasmaVirtualDesktop
instance which contains unique id, name and position.
PlasmaWindow has new events: plasmaVirtualDesktopEntered
and plasmaVirtualDesktopLeft when a window enters or leaves a desktop,
and desktops as the list of desktops is in. A window can be on
any subset of desktops, if the list is empty, it's considered on all desktops.

Summary:
Especially for Xwayland windows the compositor might not have a themed
icon name. Resulting in a task manager not having dedicated icons for
Xwayland windows.
This change deprecates the way how a compositor is supposed to set the
window icon. Instead of passing the themed icon name, it is now supposed to
pass the QIcon. In case it's a themed icon the existing way to pass to
the client is used.
Otherwise a new event is used to inform the client that there is an icon
- no data is transmitted at this point. The client can then create a
file descriptor and pass it to the compositor. The compositor serializes
the icon into the file descriptor and the client can read from it. This
all happens transparently on client side there is no api change at all.
The writing and reading of the icon is done in a thread. Due to that
Qt5::Concurrent is now a required dependency instead of an optional
dependency.

Differential Revision: https://phabricator.kde.org/D1779
Summary:
The event is sent to the client once all initial state is transmitted.
This means the client is able to see the PlasmaWindow completely created
and not in the intermediate state with further updates being pushed after
being created.
The client side API is adjusted to emit the windowCreated signal after
the initial state event is received. In addition if the window is already
unmapped, the signal will never be emitted which means the not valid
windows are not exposed to the client at all.
The tests are adjusted to reflect the new reality, which in most cases
just means removing the comment that this needs to be improved.
There is one kind of unrelated change included: when an empty icon is
set, the client side now creates a QIcon() instead of going through
QIcon::fromTheme. This wrong behavior was exposed now by the auto tests.

Summary:
So far we directly destroyed the resource on the server side. But this
causes a wayland error when the client tries to cleanup. This results in
the client being destroyed. A problem which brings down plasmashell
regularly when short living windows are shown. This happens e.g. in
Dolphin with the adress auto complete.
This change addresses the problem by creating a temporary
PlasmaWindowInterface for the already unmapped window. It doesn't get
added to the list of known windows and it's only purpose is to properly
handle the unmap and the destroy of the just created resource.

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.
