Some old platforms don't have atomic integer supports for 64-bit wise
integer.
As indicated in GPUVis:
// Erase all knowledge of this ctx so it can be reused
We can reuse numbers after end_ctx, so with we should be fine with
32-bit integer.
Let's use a 32 bit integer for context.
bind(2) expects its second parameters is a "const struct sockaddr*",
let's cast the "struct sockaddr_un*" to "struct sockaddr*" before
passing into bind(2).
SUN_LEN is a BSD extension that also implemented by GNU, let's define
_DEFAULT_SOURCE before including "sys/un.h".
When the monitor is created, the surface may already have child
sub-surfaces. The childSubSurfaceAdded signal won't be emitted for them,
we need to handle this case explicitly.
BUG: 433511
FIXED-IN: 5.21.2
In QJSEngine, QRect is an Object, which is correct. This means that we
cannot use simple assignment operator to copy geometries, we need to use
standard ways to copy Objects, such as Object.assign() or the spread
operator, which is not available in QJSEngine yet.
Summary:
QScriptEngine is deprecated for years and suffers bitrot.
Plasma hit one super major bug with it in 5.11.0 and has now ported
away.
Main porting notes:
- creating low level functions no longer exists
The old global functions are exposed on the ScriptedEffect instance
and then the QJSValue wrappers of the globalObject are modified to
trampoline the methods at a wrapper level.
- We can then use QJSEngine to automatically do argument error checking
rather than unmarshalling a QJSValue manually which significantly
reduces a lot of code.
- We can't make FPX2 a native type, so these are QJSValue args and
unboxed there.
Long term I want overloads for animate that take int/QSize/QPoint which
are native JS types, but that might be an API break.
Test Plan:
Hopefully comprehensive unit test which passes
Tested fade/fadeDesktop manually.
It's a very invasive change, so I expect some things will be broke
please help test any JS effects.

Otherwise the input method test seems to fail with the following error
"The name org.kde.kwin.testvirtualkeyboard was not provided by any
.service files"
Otherwise if powerdevil for example is configured to turn screen off on
the power key press, we will turn it right back on when we get key
release event.

According to the spec, when the pointer enters a surface, the contents
of the cursor becomes undefined. The client should call set_cursor() to
make sure that the cursor image is correct.
Currently, the wobbly windows effect assumes that the window data will
be updated on every repaint. However, there are legit cases when the
time diff between frames can be 0, for example when per screen rendering
is on.
If we are unlucky enough and the geometry of the window changes in that
very short moment, the mapping between window quads and the bezier
patch will be wrong. The window will most likely bounce back and forth.
In order to improve handling of that tricky case, this change makes the
computeBezierPoint() function take the "uv" coordinates rather than the
absolute "xy" coordinates of window vertices. This loosens the
connection between the real geometry of the window and the cached bezier
patch, and overall makes the effect's timing code more robust.
This can be also useful if the wobbly windows effect starts accumulating
time diffs and performing the integration step every N msecs with the
purpose of maintaining uniform "wobbliness" across different refresh rates.
BUG: 433187
There are a couple of reasons not to use the lambda:
* It is unnecessary. The DrmGpu has the DRM file descriptor
* If a crash occurs somewhere in the lambda, the backtrace will be hard
to read
* Instead of processing events in the destructor of the DrmBackend
class, we should keep dispatching events without involving
QCoreApplication::processEvents() until all page flips are completed.
There seems to be an interval between when you copy something from a Wayland
client and when you attempt to paste it into an X client where m_chunks.first().first
is empty, and trying to access its .data() will cause an assertion. While we can't
really gracefully handle this situation, we can at least terminate the function early
and turn the paste operation into a noop instead of a crash.
I just had that crash, this is what coredumpctl suggested it was
happening.
We don't need to make sure we're in dmabuf mode to remove the buffer.
Worst case scenario it won't remove anything. Check the spa_data before
querying in case it's null.
qEnvironmentVariableIntValue() will return 0 if the specified variable
is not set.
This means that swap events will be disabled on AMD GPUs unless the env
var is set explicitly to 1.
This is in a way working around bad protocol, input-method-unstable-v1
and also input-method-unstable-v2 does not have a way for input-method
to mark itself as "deactivated". This can happen when e.g. user closes
the virtual keyboard using swiping down or "close keyboard" button in
keyboard.
When this happens, the state between compositor, text_input and
input_method gets out of sync, compositor does not know that input
method got deactivated and hence it will continue sending various events
to it. The quick way around it is to change focus, which makes
compositor send deactivate request to input-method, that puts compositor
and input-method in sync again.
This patch aims to solve this by tracking the last state of input
method, If we know that input method is active and text input sends us
the show event, we toggle the input-method.
I will re-iterate that this is in no way proper solution, ideally
input-method-unstable-v3 or input-method-unstable-v2 even (since it is
not upstream anyway) gains the new request which essentially allows
input-method to sync enabled/disabled state with compositor.
The contents of the if branch is identical to the implementation of the
Toplevel::damageNotifyEvent() function and setReadyForPainting() will
never be called because m_syncRequest.isPending can be true only if the
window supports sync counters.
In case the compositor wants to cancel a touch sequence, we need to
ignore subsequent touch motion and touch up events until a new sequence
is initiated by the user.
Previously, it was implicitly handled by clearing the mapping table
between the touch slots and touch ids generated by kwayland-server.
