We cannot end a drag after the destroyed() signal for the source data
device is emitted because DataDeviceInterface and its d pointer are gone
by that time.
One of the most disappointing things when writing autotests is dealing
with a race condition where destructor requests are processed after all
globals have been destroyed.
With this change, the Display object will destroy all clients and their
resources before destroying the wl_display object. The good thing about
doing so is that shut down logic becomes simple. We don't have to assume
that wl_resource objects can outlive their wl_global objects, etc. The
bad thing is that it exposed a couple of pre-existing latent bugs in the
data device and the xdg foreign code.

Getting the object associated with the particular wl_resource is not
difficult, but it involves a pretty reasonable amount of boilerplate
code.
This change, introduces a helper function with an intend to reduce the
amount of boilerplate code.
It can be used as resource_cast<const ObjectPrivate *>(resource) or
just simply resource_cast<ObjectPrivate *>(resource).
Every time the icon surface is committed, we need to accumulate the
surface offset. However, this is not easy to do on the compositor side
with the current design.
This change introduces a new class DragAndDropIcon that defines a
surface role as well as accumulates surface offsets on every commit.
This fixes a bug where the dnd icon jumps all of sudden while dragging
an image from Firefox to other applications.
This change rewrites implementation of subsurfaces with qtwaylandscanner
and fixes various smaller issues, such as proper handling of position
updates for subsurfaces in the desync mode and getting rid of QPointer in
the public API.
Parenting both registry and the client connection to the test leads to a
confusing teardown order. Especially as m_connection is explicitly
deleted in cleanup()
Scoping registry to where it's actually used solves that
It is allowed to call surface_attach multiple times with the same
buffer. We want to only connect once.
Found whilst debugging a freeze, going through the list of
BufferInterface connections I had multiple to the same SurfaceInterface.
CCBUG: 428361
Currently, Firefox will stuck in "dnd" mode if you try to drag any of
its tabs. The main reason for that is that kwin doesn't send the
wl_data_source.cancelled event if the pointer button has been released
and there is no target surface or if the data source hasn't been
accepted by anyone.
CCBUG: 427528
During DataDevice migration we moved dataDevicesForSurface away from the
existing template macro due to inheritance reasons at the time.
The SeatInterface::setDragTarget() is used with null surfaces
- Get rid of the KF5 deprecated methods related to keymap,
kwayland-server is not source compatible with kwayland, so we don't
need to keep the deprecated methods
- Move the key repeat, modifiers and keymap handling fully into the
KeyboardInterface.
- Get rid of some of the keyboard related code base from the
seat_interface.

Some input related code in kwin is mislead by the fact that when the
input region is infinite, SurfaceInterface::input() is going to return
an empty QRegion object.
We cannot really do that because the client could have just set a valid
empty wl_region object to ignore all input events.
This change makes SurfaceInterface assign an actually infinite region
when a NULL input region has been passed to set_input_region().
modifiers request by the input method is supposed to send the raw
modifiers based on the keymap of the keyboard grabbed as result of the
grab_keyboard request. If input method client is not using the keysym
functionality it can decide to not send out the modifiers_map, since it
is already known to compositor as part of keymap event sent by it.
While at it also guard against empty modifiers_map, if this happens
ideally compositor should handle that information based on the keymap
sent out using grab_keyboard function, but since currently, we do not
have the grab_keyboard implemented in here, send out the NoModifier if
that happens.
When touching a surface that doesn't register to wl_touch events, KWin
didn't send frame events (which it does for regular pointer and touch
events), causing severe updating issues with some clients.
Test Plan:
Launch a client that doesn't attach to wl_touch (for instance,
rootston) with WAYLAND_DEBUG=client and watch the logs while touching
its window.
The xdg-output spec omits whether the compositor has to destroy all xdg-
output resources when the associated wl_output global is removed.
This means that no xdg-output resource should be destroyed unless the
client has called the destructor request; otherwise the client may panic
due to protocol errors.
Starting with Qt 5.15.2, it's okay to destroy generated wrapper objects
without destroying associated resources. Destructor requests will be
handled behind the scenes for inert and orphaned resources by code that
is generated by qtwaylandscanner.
BUG: 426293
If we track the commit counts at compositor global, this will fail
horribly for anything other than the first text-input-v3 client, as for
new client the serial count will not be what it expects in the done()
request and it will simply consider events as outdated and will refuse
to accept those events
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.
If a frame callback resource is destroyed, it will unregister itself
from corresponding lists in current, pending, and cached state.
However, this means that we need to be super duper careful when the
compositor wants to destroy all frame callbacks. We need to make a copy
of a frameCallbacks list; otherwise a call to removeOne() will
invalidate iterators and the compositor may crash.
Currently, that copy is made implicitly. Some people may see that code
and add qAsConst() without realizing the consequences it will lead to.
This change improves the readability of that code by making explicit
copies of frameCallbacks in code that shuts down SurfaceInterface.
This was done mostly because I wanted to get rid of the Resource
dependency in AbstractDataSource so I can make our xwl bridge direct,
but this also fixes up some issues with object lifespan present in the
previous version and keeps all our clipboard code in-line.
When the focusedTextInputSurfaceChanged() signal is emitted, it is
expected that SeatInterface::focusedTextInputSurface() will return
the new focused text input surface.
