Summary:
The syncing of the window geometry to the internal geometry can
unfortunately cause a freeze in very special conditions:
1. create QML component
2. a Plasma::Dialog gets created
3. It creates the DialogShadows
4. This triggers QGlobalStatic creation which locks a non-recursive
mutex
5. The creation of DialogShadows creates a Registry and triggers a
roundtrip on the Wayland server
6. KWin processes all Wayland events
7. This triggers the creation of a ShellClient
8. The ShellClient has a PlasmaShellSurface which requested a position
9. The new geometry does not match the geometry of the Plasma::Dialog
10. ShellClient syncs the geometry to the Plasma::Dialog
11. Plasma::Dialog updates the theme because window geometry changed
12. This accesses the DialogShadows...
which is still in the non recursive mutex and we have a freeze.
By delaying the sync to the end of cycle we jump out of this deadly
sequence.
BUG: 384441
Test Plan:
The freeze doesn't hit any more. It's possible that some test
cases need adjustments.

Summary:
Bringing another caption feature from X11 to Wayland. If we have
multiple windows with the same caption, starting from the second window
a suffix <number> is added.
E.g. if we have three windows with caption "foo", the naming is:
* foo
* foo <2>
* foo <3>
The change tries to use as much shared code between the X11 and Wayland
implementation. Unfortunately it's not possible to share completely as
the X11 implementation does X11 specific things like editing the visible
name.
By sharing the code the numbering also works cross windowing system.
That is if a window is called "foo" on X11, a new window on Wayland with
caption "foo" will get adjusted to "foo <2>" and vice versa.
The change also eliminates a duplicated signal for captionChanged in
ShellClient (found by test case).
By using the shared implementation on X11 side a bug gets fixed which
got introduced with the support of "unresponsive", this is no longer
considered and the numbering still works even if there is a window which
is unresponsive.

As I don't want to include abstract_client.h in workspace.h a new enum
is created for the quick tiling flags used in Workspace. This caused a

Summary:
So far KWin did not properly handle popup windows. That is when a popup
surface got created and a click outside the surface happened KWin did not
send out the popupDone Wayland event.
This change makes KWin aware of whether a surface is a popup and tracks
through a new PopupInputFilter whether there are popup windows. In case
there are popups the new filter waits for mouse press events and cancels
the popups if the press does not happen on any surface belonging to the
same client. To quote the relevant section of the Wayland documentation:
The popup grab continues until the window is destroyed or a mouse
button is pressed in any other client's window. A click in any of the
client's surfaces is reported as normal, however, clicks in other
clients' surfaces will be discarded and trigger the callback.
So far the support is still incomplete. Not yet implemented are:
* support xdg_shell popup windows
* verifying whether the popup is allowed to be a popup
* cancel the popup on more global interactions like screen lock or

This brings back global menu support in KWin.
The DBusMenu infrastructure is different that we just read the DBus service name and

Differential Revision: https://phabricator.kde.org/D3089
Summary:
The OnScreenNotification gets moved during its placement. This update
of the geometry did not get synced to the QWindow's geometry as it
should.
The reason for this is the rather special implementation of
AbstractClient::move. This just modifies the geom variable and does not
call into setGeometry at all. Instead a virtual doMove method is invoked
to inform the platform specific client implementation about the move of
the window. For a "normal" ShellClient that is fine - there is nothing
to do.
This change adds an implementation of doMove in ShellClient to sync the
geometry to the internal window. This is not yet enough to fix the
geometry of the OnScreenNotification. It gets placed with a
GeometryUpdatesBlocker in place causing the doMove never to be called.
Instead setGeometry is invoked again when the geometry updates get
unblocked. So far ShellClient did not do anything in this case. This
change ensures that at least the doSetGeometry method is performed again.

Summary:
AbstractClient gains a new pure virtual killWindow method and this gets
implemented in ShellClient.
ShellClient performs the killing by sending a term signal to the
process. This can only work if the client connected through the socket
and didn't get a socketpair fd passed. In that case the pid is KWin's
and KWin doesn't want to terminate. Thus this is special handled to
destroy the connection instead.
In case terminating the process has no effect, the connection gets
destroyed after five seconds.
The KillWindow is adjusted to operate on AbstractClient instead of
Client.
This implements T4463.

So far KWin used the window title provided from the window directly
without any sanitizing. This could result in broken window decorations
if the title included line breaks. Those were passed to the decoration
and depending on the way how the decoration renders the title, it could
result in visual breakage.
Having line breaks in a window title doesn't make sense. Given that KWin
now simplifies the title when copying it to it's own structure. This
also ensures that the title passed to e.g. task manager does not have
any line breaks on Wayland.

Summary:
KWindowSystem provides a KDE specific property for the desktop file
name. This allows KWin to take the icon from the desktop file. The
advantage from the desktop file is that KWin normally gets higher
resolution icons than provided through the xproperty based icons used
previously. If the desktop file does not provide an icon name, KWin
falls back to the previous implementation.
As on Wayland the icon is taken from the desktop file name already the
code for X11 and Wayland is merged in AbstractClient. Also to the
PlasmaWindowInterface the appId is taken from the new desktop file
instead of the resourceName. Due to that for Xwayland windows where KWin
knows the desktop file name it can be passed to PlasmaWindowInterface.
This allows e.g. the task manager to better map the windows to
applications and provide better icons. Also it means that icons do not
need to be passed as bitmap data to the clients.
Test Plan:
Verified that icon is taking from desktop file if provided and
from X property if not provided and that Wayland windows still have icon.

Summary:
On Wayland the QtExtendedSurface is used to pass the path to the color
scheme using the generic window property. To support this ShellClient
installs an event filter on the extended surface and listens for dynamic
property change events.
As the color scheme is KDE specific anyway it is not a problem that a Qt
specific interface is being used. For other toolkits just passing the
name to KDE's color scheme isn't sufficient anyway. If at some point we
find a way to support this for e.g. GTK+ we would need to come up with a
dedicated interface.

Plasmashell's desktop windows are RGBA which forces the compositor to
perform blending and render the background. That is absolutely pointless

rendering which will never be visible (including shader push/pop).

be considered as opaque by setting the depth to 24. Thus blending is
disabled and the background is not rendered.
