There's no need to derive. This fixes the build with MSVC 2017 under
/permissive-. I don't know what was wrong (ICC, Clang and GCC don't
complain), but it must be related to "Lookup members in dependent base"
in [1].

Even if a callback type is not automatically re-enabled, callbacks are
implicitly enabled when the source has been added to the run loop.
In this case, calling CFSocketEnableCallBacks() could produce an extra
notification if there is a pending event in the queue.
The bug is quite unstable and completely depends on the internal OS
delays. So, it can't be tested inside Qt.

There were still two cases where spurious notifications would be
possible:
- user calls hasPendingDatagrams()/pendingDatagramSize() on UDP
socket somewhere outside the slot connected to readyRead()
signal (::WSARecvFrom posts FD_READ notification, even if
a notification for incoming datagram already exists in the
message queue);
- a socket was registered to receive several types of event and
WM_QT_ACTIVATENOTIFIERS message is located between the
different events for this socket in the queue.
Provided patch ensures that the message queue is synchronized with
the Qt event processing mechanism and adds a way to detect spurious
notifications inside the window procedure.

... as this would require us to remove usage of QAbstractEventDispatcher::flush
from Qt source code as well. We can not do this already in Qt 5.9 as there are
few event dispatchers in Qt that actually do override the ::flush (with non empty
bodies). Removing this code could result in behavior changes (not very likely) for
some user code. This method will be removed in Qt6.
Instead mark it with a well known "### Qt{Version}" comment.
This patch amends 41eefd7. The warning was:
qcoreapplication.cpp: In static member function ‘static void QCoreApplication::flush()’:

... as it has outlived its original purpose:
Qt3 implementation on X11:
void QApplication::flush() { flushX(); }
void QApplication::flushX() { if (appDpy) XFlush( appDpy ); }
Qt4 implementation on X11:
Did nothing when QApplication::flush() was called (the flush()
overrides in {unix,glib} event dispatchers with empty bodies).
In Qt5 this function somehow has been repurposed (inconsistently)
to do what QCoreApplication::sendPostedEvents already does:
QAbstractEventDispatcher::flush() = 0;
=> QCocoaEventDispatcher::flush() {}
=> QEventDispatcherCoreFoundation::flush() {}
=> QIOSEventDispatcher (does not override ::flush())
=> QEventDispatcherGlib::flush() {}
=> QPAEventDispatcherGlib (does not override ::flush())
=> QEventDispatcherUNIX::flush() {}
=> QUnixEventDispatcherQPA (when QT_NO_GLIB=true)
::flush() { if (qApp) qApp->sendPostedEvents(); })
==> QAndroidEventDispatcher (does not override ::flush())
=> QEventDispatcherWin32::flush() {}
=> QOffscreenEventDispatcher::flush() {
if (qApp) qApp->sendPostedEvents();
QEventDispatcherWin32::flush();
}
=> QWindowsGuiEventDispatcher (does not override ::flush())
=> QWindowsDirect2DEventDispatcher (does not override ::flush())
=> QEventDispatcherWinRT::flush() {}
=> QOffscreenEventDispatcher::flush() {
if (qApp) qApp->sendPostedEvents();
QEventDispatcherWinRT::flush();
}
=> QWinRTEventDispatcher (qminimaleglintegration.cpp) (does not override ::flush())
=> QWinRTEventDispatcher (qwinrteventdispatcher.h) (does not override ::flush())
Whatever this function was doing on macOS in Qt3 and Qt4 also has been
dropped in Qt5. It appears that the other event dispatchers in Qt5 that
have overrides for flush() have simply copy-pasted this logic.
Clearly the documentation of QCoreApplication::flush() is outdated and
has nothing to do with the actual implementation in Qt5.
This function is rarely used in Qt5 sources. It should be safe to remove
the calls to QCoreApplication::flush() from Qt source code, as this
function has been doing nothing on most platforms anyways. Repurposing
it even broke handling of posted events (see QTBUG-48717).
[ChangeLog][QtCore][Event loop] QCoreApplication::flush() is now
deprecated. Use QCoreApplication::processEvents() and
QCoreApplication::sendPostedEvents() instead.

This was simply not working for two reasons:
- The index passed to QMetaObject::metacall was not right (there was an offset
because of the return type)
- If the registration succeeded, the arguments were not even initialized.
The tests in tst_moc always called QMetaMethod::parameterType before calling invoke,
which was properly registering the type. So this was not seen in the tests before.

This reverts commit 47cc9e23a313d67a4a3107242f205d2473842021.
We use QCoreApplication::applicationDirPath in the logging initialization to find
a possible qtlogging.ini file. Because QCoreApplication::applicationDirPath requires
a QCoreApplication instance this leads to a qWarning, which in turn leads to a
recursive call to the logging initialization, and in turn to a recursive mutex deadlock.

The developer should see what's wrong even on release builds.
That code hides any mistakes we do in JNI which are pretty critical
for developers because they can't see what's wrong with their code. e.g.
QtAndroid::activity().callMethod<void>("wrongMethodName")
*silently* fails, which is so wrong!

std::nullptr_t is nullary: it accepts only one value, nullptr. So we
don't need to read or write anything. This commit simply adds the two

though there's no change in behavior.

Some compilers are known to complain about this with a warning. GCC
complains about const on return values on -Wignored-qualifiers (enabled
at -Wextra), so it's not too much of a jump to assume that others do
too. Besides, this is not Qt Library API policy. As maintainer for
QtCore, I'm exercising my prerrogative in specifying certain unspecified
parts of the coding style, like I've done for constructor initializer
lists.
Since all the classes involved are exported (including QVector, through
derived classes), we can't remove the qualifier until Qt 6, since there
are compilers known to encode the qualifier in the mangled name
(suncc). I'm not introducing #ifdef to silence unknown compilers unless
we get an actual complaint.

Timer IDs have been reused since Qt 4.5 or thereabouts, so just checking
if the timer ID is in the timer dictionary is an incorrect check: our
timer may have been deleted and replaced by another with the same ID.
Instead of deleting the WinTimerInfo object, let's just mark it as
unregistered by setting timerId to -1 and cooperate in deleting at the
appropriate places. Since unregisterTimer skips deleting if inTimerEvent
is true, the appropriate places are everywhere that set inTimerEvent to
true.

For the windows file system engine, we add an extra macro to use
library loading if configured to do so, but avoid it on WinRT, as
none of the symbols would be found.
We also QT_REQUIRE_CONFIG(library) in the library headers and
exclude the sources from the build if library loading is disabled.
This, in turn, makes it necessary to clean up some header inclusions.

Commit fb376e0fcc8d2d0a1731a588bfc6497d05e090e6 removed an array that
facilitated returning the names of built-in types, to avoid the jump tables
from the switch statement. This commit brings it back but makes the array a
compile-time constant string offset table.
The array is created by way of a set of C++11 constexpr functions, so we
require that compiler feature. I've tested that MSVC 2015 does support
it as well as the ICC 17 when masquerading as MSVC 2015, so I've enabled
for that too. The only compiler left out is MSVC 2013.
If we didn't need to support MSVC 2015, this could have been written
more simply with C++14 relaxed constexpr.
This also adds unit tests to confirm that QMetaType::typeName() does
return null when we said it would. We're testing QMetaType::User-1
(which we'll likely never use) and QMetaType::LastWidgetsType-1 to
select something inside the range of the built-in types.

RunLoopModeTracker as one of Qt Cocoa classes was not wrapped
in namespace which limited its use in Objective-C single symbol space.

This adds the tabletTracking property in the same way that mouseTracking already
existed: there is a WA_TabletTracking attribute, and a TabletTrackingChange event
to notify when it changes. So for widget applications it's an opt-in feature.
QtQuick applications don't yet make use of tablet events, but when they do
in the future, we don't yet have a mechanism to turn the move events off;
it remains to be seen whether that will be necessary.
[ChangeLog][QtWidget] QWidget now has a tabletTracking property, analogous
to mouseTracking, which will enable TabletMove events while the stylus is
hovering, even if no button is pressed. This allows applications to show
feedback based on the other tablet event properties such as rotation and tilt.

QObject::connect will extract the QArgumentType for first the signal,
then the slot. The QArgumentType with a string constructor will query
the metatype system to get the meta type id. But it might happen that
between the extraction of the signal's argument and the slot's argument,
qRegisterMetaType was called in another thread. For this reason, it's
possible that one QArgumentType has a type id while the other does not.
For this reason, we should fall back to compare the string if any of
the argument's type is 0.

Adding 0 each time will obviously not produce a new identifier each
time...
Also use static initialization for QBasicAtomicInt.
A default-constructed static QBasicAtomicInt at function scope
will be dynamically initialized. It will still be zero-initialized,
but at least GCC adds guard variables for such objects.
When using aggregate initialization, the guard disappears.

It was unnecessary, since we only cached the static types, which are all
generated by the macro anyway. The way it was implemented, this produced
data races that are strictly-speaking UB, even if all the threads were
writing the same values to the same data locations.
This commit changes a little the code to simplify, since we're changing
those lines anyway.

If the QSemaphore::tryAcquire() call times out, we mustn't
touch *res, because there was no happens-before relation
established between *res = result in the lambda and our
returning *res;
Fix by returning a default-constructed hash in that case.
Add a strategic std::move().
The same problem exists in runOnAndroidThreadSync(), but
I have no idea how to solve it, because there the shared
object is the runnable itself.

The code obtained an iterator into a QHash under mutex protection,
then dropped the lock, dereferenced the iterator several times and
only retook the lock to erase the element from the QHash.
This is very smelly. QHash provides no official iterator validity
guarantees, and the container isn't const, either (which would imply
thread-safety). In particular, the dereference into the container
outside the critical section is cause for concerns.
Simplify the code, removing any doubts about its race-freedom, by
taking the payload item out of the hash before dropping the lock, and
using only the local strong reference in the remainder of the
function.
The only other references to g_pendingPermissionRequests are
insertions with unique-by-construction keys in QtAndroidPrivate's
requestPermissions(), so there was no reason to keep the item in the
hash for the whole duration of the sendRequestPermissionsResult()
call.
