QWidget and QWindow use bits in QObjectPrivate to provide for a couple
of shortcuts -- one in qobject_cast, and another in the isWidgetType() /
isWindowType() functions in QObject. These can be optimized by simply
looking at the bits, without actually doing more expensive runtime
casts.
These bits were set on construction, but not unset on destruction. The
result was for instance that destroying a QWidget would report that the
object was still a QWidget when ~QObject was reached.
Fix this
1) by setting the bits only when QWidget / QWindow constructors start;
2) by resetting the bits once ~QWidget / ~QWindow are completed.
Technically speaking this is not 100% correct in the presence of data
members, but luckily those classes don't have any.
Amend an existing test for QWidget (whose comment said exactly the
opposite of what the test actually did) and add a test for QWindow.
Some other code was wrongly relying on isWidgetType() returning true
for destroyed QWidgets; amend it as needed.
[ChangeLog][QtCore][QObject] Using qobject_cast on partially constructed
or destroyed QWidget/QWindow instances now yields correct results.
Similarly, using the convenience isWidgetType() / isWindowType()
functions now correctly return false on such instances. Before,
qobject_cast (and the convenience functions) would erroneously report
that a given object was a QWidget (resp. QWindow) even during that
object's construction (before QObject's constructor had completed) or
destruction (after QWidget's (resp. QWindow's) destructors had been
completed). This was semantically wrong and inconsistent with other ways
of gathering runtime type information regarding such an object (e.g.
dynamic_cast, obj->metaObject()->className() and so on).

We were clipping the source rect to the image, both pre and post
scrolling, but did not apply the same logic to the target position.
By computing the target position based on the already clipped source
rect we ensure that the target position is also correct.
This was causing valgrind warnings on Linux, and crashes on Windows,
when trying to test the lower level QBackingStore::scroll() function.
The reason we were not seeing this in practice was that QWidget does
its own sanitation and clipping of the arguments before passing them
on.
As a drive-by, fix the access of image to use constBits instead of a
manual cast, and rename variables to better reflect their use.

After 556511f9f3, which moved the resolve
mask storage into the palette's d-pointer, modifying the resolve mask
requires a detach. As of now, we only detached when setting a different
brush, but always modified the resolve mask, which broke palettes that
shared the d-pointer (likely the global default palette).
However, detaching has negative side effects when styles set brushes on
temporary palette objects and then use that palette object's cache key
to build a cache of pixmaps. As each drawing would detach the palette
(even if the palette doesn't change, which is likely), the cache key
changes with each detach, and the cache would quickly increase in size.
This was addressed in changes d7bcdc3a44
and 1e75dcf251.
We can either detach and find other ways to address the issues from
QTBUG-65475, or we can not change the resolve mask when the brush doesn't
change and completely ignore the call.
Since QFont ignores the setting of any attribute to a value that is
identical to the current value, and since it's possible to force that
the resolve-bit is set by calling setBrush twice with different brushes,
ignoring the call seems like the better solution.
[ChangeLog][QtGui][QPalette] Setting a brush on a palette that is
identical to the current brush no longer sets the resolve mask bit for
that particular role, so items using the palette will continue to
inherit changes from parent items.

The QtTest best practices documentations recommends using output
mechanisms such as qDebug() and qWarning() for diagnostic messages,
and this is also what most of our own tests do.
The QWARN() macro and corresponding internal QTest::qWarn() function
was added when QtTest was first implemented, but was likely meant as
an internal implementation detail, like its cousin QTestLog::info(),
which does not have any corresponding macro.
This theory is backed by our own QtTest self-test (tst_silent)
describing the output from QWARN() as "an internal testlib warning".
The only difference between QWARN() and qWarning(), besides the much
richer feature set of the latter, is that qWarning() will not pass
on file and line number information in release mode, but QWARN() will.
This is an acceptable loss of functionality, considering that the user
can override this behavior by defining QT_MESSAGELOGCONTEXT.

When a foreign event loop that does not enter an alertable wait state
is running (which is also the case when a native dialog window is
modal), pipe handlers would freeze temporarily due to their APC
callbacks not being invoked.
We address this problem by moving the I/O callbacks to the Windows
thread pool, and only posting completion events to the main loop
from there. That makes the actual I/O completely independent from
any main loop, while the signal delivery works also with foreign
loops (because Qt event delivery uses Windows messages, which foreign
loops typically handle correctly).
As a nice side effect, performance (and in particular scalability)
is improved.
Several other approaches have been tried:
1) Using QWinEventNotifier was about a quarter slower and scaled much
worse. Additionally, it also required a rather egregious hack to
handle the (pathological) case of a single thread talking to both
ends of a QLocalSocket synchronously.
2) Queuing APCs from the thread pool to the main thread and also
posting wake-up events to its event loop, and handling I/O on the
main thread; this performed roughly like this solution, but scaled
half as well, and the separate wake-up path was still deemed hacky.
3) Only posting wake-up events to the main thread from the thread pool,
and still handling I/O on the main thread; this still performed
comparably to 2), and the pathological case was not handled at all.
4) Using this approach for reads and that of 3) for writes was slightly
faster with big amounts of data, but scaled slightly worse, and the
diverging implementations were deemed not desirable.

it calls QWindowSystemInterfacePrivate::fromNativeTouchPoints to

Therefore we must give that function touchpoints that are actually in
