During QCoreApplication initialization, we create the main thread's event
dispatcher, which for a GUI app happens via QGuiApplicationPrivate's
createEventDispatcher() override. This in turn relies on the platform
integration to create the event dispatcher, but to do that it needs to
create the platform integration first. And this might result in calling
APIs that themselves initialize the main thread event dispatcher, such
as QEventLoop, which non-lazily creates an event dispatcher for the thread.
We already had a check to catch the platform integration setting the
QCoreApplictionPrivate::eventDispatcher member, but not anything for
checking the current thread data.
On macOS this resulted in a leak of QEventDispatcherUNIX because
QCocoaDrag contained a QEventLoop member. We now track the event
loop temproarily via a pointer instead, like we do in other places.
An alternative fix would be to defer the initialization of QCocoaDrag
until QCocoaIntegration::drag() is called, but that would run the
risk of something calling the function during platform initialization
and we'd be back to the same problem.
It's unclear why QEventLoop is not lazily ensuring the event dispatcher,
and this might be a wider fix for similar issues.

In Qt >= 6.1, < 6.5, a trivially constructible type would have the
NeedsDestruction flag set, but it's dtor pointer would have been null.
In Qt 6.5, the meaning of the NeedsDestruction flag was changed to be
more aligned with what the name suggests, and thus would only be set for
non-trivially destructible types. For QMetaType this was fine, but
QVariant has a check for acceptable metatypes which attempts to verify
whether a QMetaType is usable for QVariant. The check assumes the
semantics of Qt 6.5, and thus fails for metatypes created by older Qt
versions.
To fix this issue, we increment the QMetaType revision field, and only
check the metatype's destruction support if the revision is high enough.
In theory, that allows passing unsuitable metatypes from older Qt
versions to QVariant; however, such code would have been broken in prior
Qt releases already (which didn't attempt the check), and no code that
used to work in any released Qt version will break (as we simply skip a
check that was passing before).

To fix the broken sliders reported in QTBUG-98093 a workaround was
added by 4bee9cdc0a where we would
call initWithFrame on an already initialized NSSlider.
This breaks the contract of object initialization in Objective-C,
as the class is free to allocate and prepare resources for the
instance without freeing previously acquired resources first.
As noted by the Object Initialization chapter of the Concepts
in Objective-C Programming guide, "Once an object is initialized,
you should not initialize it again.":
https://tinyurl.com/objc-object-init
And as observed in QTBUG-112899, the additional initialization
resulted in a memory leak.
The other part of 4bee9cdc0a
was that we now called startTrackingAt twice when drawing.
Both from setupSlider, for all consumers, and from
drawComplexControl, and as it turns out, this is the key
thing that "fixes" the pressed knob drawing of NSSlider.
For some reason, NSSlider needs the duplicate startTrackingAt
call both to draw the knob as pressed, and to not let one
drawing pass affect another drawing pass. This would benefit
from further investigation, but for now the removed leak
is an improvement.

mutex *does* release the contents of the object to memory, but without
the corresponding mutex acquisition, we couldn't guarantee that the
object's contents would be observed. Now we can.
We don't need to fix the load inside the mutex because the mutex will
have acquired everything from either a previous call to pointer() or to
reset(). The store inside reset() need not be storeRelease() either
because the effect of observing the Uninitialized state will be to lock
the mutex.
None of this is used to protect the data as it is being mutated by the
user in multiple threads, or their access simultaneously with reset()
(which is why the load outside the mutex was removed).

Functions in Qt that take a callback need to support callables with or

implementation of those overloads follows a pattern that ultimately
results in a QSlotObjectBase implementation being created and
passed to an implementation helper that takes care of the logic.
Factor that common pattern into a new helper template in QtPrivate
that returns a suitable QSlotObjectBase after checking that the
functor is compatible with the specified argument types.
Use that new helper template in the implementation of
QCoreApplication::requestPermission and QHostInfo::lookupHost.
The only disadvantage of centralizing this logic is that we cannot print
a more detailed error message indicating which argument types the
caller expects. However, that information is visible from the detailed

Problem: "ninja clean" does not fully clean the build directories of
configure-time executables (e.g. syncqt). This can lead to problems when
building with compiler and linker launchers: on configure time, the
launchers are not used (compare CMake issue #20762). After a "ninja
clean", the executable might be removed but the object files are still
there. This leads to a situation where the object files have been
created without the compiler launcher but are linked with the linker
launcher. We encountered a situation however, where the linker launcher
requires the usage of the compiler launcher.
The configure-time executable has a ${target}_build custom command that
runs "cmake --build" and creates a timestamp file to track when to build
the target. To circumvent the problem of stale object files we add the
"--clean-first" argument to that target to fully rebuild configure-time
executables if the timestamp file is out of date.
The performance this imposes is negligible, because
1. Those configure-time executables are seldom out of date.
2. They are supposed to be "tiny executables with system dependencies
only" anyway.

Move the logic of updating the scoll offset into the makeVisible

between the last tab and the right edge of the widget of there is still
a scroll; or to reset it to 0 if there is enough space for the entire

cannot skip this when the buttons are invisible. However, the

This commit introduces fine-grained Bluetooth permissions control to
the QBluetoothPermission class.
For now the fine-tuning of the permissions is only supported on
Android. On Apple enabling any of the permissions is equivalent to
requesting full Bluetooth control.

The crash is caused by the cleanup sending trace messages when the
plugin has already been destroyed. Add shutdown callback to the plugin
to indicate this has happened. We can't use signals since that also
generetes trace event.
