The following order of events are legal:
Typically order is:
- server announces a new output
- client binds to a new output
- server updates the surface to be on new output
But we can have events occur in the following order:
- server announces a new output
- server updates the surface to be on new output
- client binds to a new output
At which point when we update the surface there is no ID to tell the
client which output the surface is on.
This patch watches for clients binding to output and updates
appropriately.
Be more explicit about the types, prefer passing semantically correct
parents and keep track of the pads from the object rather than relying
on them being initialised properly.
We send modifiers to the active client when they change, and when we
focus an existing client we send the cached state.
For this reason it's important we always update our internal store of
modifiers regardless of whether a surface is currently active.
Unit test is adopted accordingly.
BUG: 429930
The main reason why we have factory methods is that up to some point,
kwayland had its own signal to indicate when globals have to be removed.
Now that all globals add destroy listeners for the wl_display object,
we don't have that signal. Most factory methods are equivalent to doing
new T(display).
Besides adding unnecessary boilerplate code, another reason to get rid
of the factory methods is to reduce the amount of merge conflicts. If
several persons work on implementing wayland protocols at the same time,
sooner or later someone will have to resolve merge conflicts in Display.
libwayland-server allows the wl_display accept client connections on
more than one socket. We currently don't listen on multiple sockets,
but it would be nice if Display supported such operation mode.
And make them public in th keyboard_interface, there's no point in
wrapping this in seat_interface with new approach

A threshold exists to stop users flooding the server for no reason.
However, there is a usecase for small timeouts.
rsibreak has a "please relax for 20 seconds" interface. Here it makes
perfect sense to know if a user is active in small increments. The plan
is to start a 1s timer and wait for that. Then we wait locally for 20s
without a resume event.
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.
closesplasma/kwayland-server#2
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.
