d517d5428c Use qFuzzyCompare instead of qFuzzyIsNull in QPointF ==
qFuzzyIsNull has a fixed range, where qFuzzyCompare can tell if numbers
are different in a more relative range. Without it QPointFs that are
heavily scaled will be interpreted as identical, when they are quite
different at their own scale.

e15fc26e9f QSortFilterProxyModel: don't assert when old model gets destroyed
When a new model was set with setSourceModel() and the mapping was
built up, the destruction of the old model caused a reset in the
QSortFilterProxyModel which lead to an empty view or an assertion.
Now we properly disconnect the old model again and also clean up the old
mapping/persistent indexes when a new source model is set.

883d58dacd Fix tst_QDoubleSpinBox::editingFinished failing after other tests
Wait for the spinbox to show become active in the previous test. Also use
QWidget::activateWindow() instead of QApplication::setActiveWindow(). Use of the
latter seemed to result in some confusion where QWidget::isActiveWindow()
returned true but QWindow::isActive() on the underlying window returned false,
leading qWaitForWindowActive() to fail.

Also remove superfluous setting of focus. It was just set and verified.

ae8743bf86 tst_QCommandLinkButton: Add back wait to the beginning of setAutoRepeat()
setAutoRepeat() is failing on macOS and Windows when run together with
defaultAndAutoDefault(). It succeeds when run on its own. Adding the wait allows
it to succeed when run with the other tests as well.

Amends 0cb940b1d3, which removed the wait.

The comment is the same as before. I couldn't see a better way to replace the
wait (QApplication::topLevelWidgets() already returns only the testWidget and
testWidget->isActiveWindow() returns true).

Another theory I had was something waiting for the KeyRelease so I changed
QApplication::sendEvent() uses to QTest::keyClick(). It did not help but that
still seems preferable.

8e47474baf QJsonDocument: Avoid overflow of string lengths
The added test case contains the binary JSON equivalent of

    ["ž"]

with the modification that the string's length has been set to INT_MAX. In
Value::usedStorage this length is used through the pointer d like so

    s = sizeof(int) + sizeof(ushort) * qFromLittleEndian(*(int *)d);

Because 2 * INT_MAX is UINT_MAX-1, the expression as a whole evaluates to 2,
which is considered a valid storage size. However, when converting this binary
JSON into ordinary JSON we will attempt to construct a QString of length
INT_MAX.

Fixed by using String::isValid instead of Value::usedStorage. This method
already takes care to avoid the overflow problem. Additionally, I've tried in
this patch to clarify the behavior of Value::isValid a bit by writing it in a
style that is hopefully more amenable to structural induction.

Finally, the test case added in my previous patch had the wrong file extension
and is renamed in this one.

5134ff882a OpenSSL v1.1.1: fix qtbug18498_peek
Previously the test worked because the client was the last party to know
when encryption was established. However, due to changes in the TLSv1.3
handshake the server is now the last one.

In either case, relying on both to be encrypted when one of them is
finished is not great, so now we only quit the event loop when both
client and server have emitted 'encrypted'.

93e0ff037e QJsonDocument: Validate also zero-length objects
The added test case is the binary JSON equivalent of

    {"a":{"š":null}}

with two modifications. First, the length of the string "š" has been corrupted
to 0xFFFFFF00. Second and more import, the Base::size field of the inner object
has been reset to 0.

On its own the first modification would normally trigger a validation error.
However, due to the second modification the Value::usedStorage for the inner
object evaluates to 0, completely disabling all further validation of the
object's contents.

Attempting to convert this binary JSON into standard JSON will lead to the JSON
writer trying to construct a QString of length 0xFFFFFF00.

Fixed by validating also objects with usedStorage == 0.

The reason it crashed was this:
1. Button was pressed => _panTimer started with the graphics view as

2. Button was released => the graphicsview is destroyed
3. 300 ms later: Qt tries to deliver TimerEvent from _panTimer to the
   graphics view. Unfortunately, the graphics view is deleted, but Qt
   doesn't know that... (*crash*)

We therefore chose to start the timer with a destination we are controlling the

check if the actual target is already destroyed.

309dacedac Atomics: remove requirement for alignment equality with plain types
This was originally added so that you could replace a T with
QAtomicInteger<T> in the same class and still keep ABI. However, for
legacy reasons, on 32-bit x86, types larger than 4 bytes keep an old
1990s alignment of only 4 bytes, but modern std::atomic<T> for those 8-
byte types enforces an alignment of 8 bytes. Therefore, the requirement
to keep alignment is not possible to guarantee.

In other words: you may not replace T with QAtomicInteger<T> or
std::atomic<T> and assume no ABI breakages in all platforms.

This is a requirement to implement atomicity. An 8-byte type aligned to
only a 4-byte boundary could cross a 16-byte boundary or, worse, cross a
cacheline boundary. Crossing the 16-byte boundary could be bad on some
processors, but crossing the cacheline boundary (addresses ending in
0x3C, 0x7C, 0xCC and 0xFC, or 4 out of 64 possible addresses or 6.25%)
is always bad: the CPUs cannot guarantee an atomic load or store
operation.
