22fbb5be6e Clear focus if the widget being deleted is the parent's focus child.
If a widget is deleted as a result of a window activation changed then
it is possible that the parent does not clear the focus because of the
activation change. If the focus child is actually part of an embedded
widget in the graphicsview then it needs to be handled explicitly in
this case too.

5d192deed9 Fix crash on qdbus when return type is a raw dbus type

it basically means unresolved and when you try to access the string data
go to a index that doesn't exist

So what I do is save the return type in rawReturnType if it is a raw
one and reassign the type to IsUnresolvedType | strings.enter(mm.rawReturnType)
instead of -1 when "saving" the metaobject

9f8a724cda Work around msvc /clr LNK2005 errors with QList
This patch fixes a compatibility with Qt 5 and Microsoft C++ /clr mode.
The QList copy constructor defines a Cleanup class that causes LNK2005
errors. It is a compiler problem, but the patch is simple. The use of
QT_TRY/QT_RETHROW instead of a Cleanup class is more consistent with other
Qt code, so is arguably preferable even without the compiler bug.

Fixes race between QDBusConnectionPrivate::processFinishedCall()

QDBusPendingCallPrivate) and deletion of the QDBusPendingCallPrivate
object through QDBusPendingCall::d's destructor (a member of type

segmentation fault with CrashTest example on slow/single core

72ecf5a7ec Remove QDBusPendingCallPrivate::autoDelete logic.
First step to fix race condition about deleting QDBusPendingCallPrivate.

In a multithreaded application on a slow/single core cpu the following
race (and segmentation fault) can occur:

First thread A is running:
A:  QDBusPendingReply<> reply = pi->asyncCallWithArgumentList(method, argumentList);

Then when the dbus answer arrives thread B will call:

B:  QDBusConnectionPrivate::processFinishedCall()
B:      ...
B:      locker.unlock()

and runs until here, go on with thread A:

A:  reply.waitForFinished();
A:    QDBusPendingCallPrivate::waitForFinished()
A:    {
A:        QMutexLocker locker(&mutex);
A:        if (replyMessage.type() != QDBusMessage::InvalidMessage)
A:            return;

which returns immediately (mutex acquired, replyMessage alread set), now
reply goes out of scope (destructor called) and QDBusPendingCall::d's
destructor of type QExplicitlySharedDataPointer<QDBusPendingCallPrivate>
deletes the reference counted object QDBusPendingCallPrivate.

Now thread B continues, still in processFinishedCall()

B:      if (call->watcherHelper)
B:          call->watcherHelper->emitSignals(msg, call->sentMessage);
B:
B:      if (msg.type() == QDBusMessage::ErrorMessage)
B:          emit connection->callWithCallbackFailed(QDBusError(msg),
B:              call->sentMessage);

accessing alread deleted object QDBusPendingCallPrivate via call->...

Fixed QDBusPendingCallPrivate deletion by proper reference counting
will be done in the next commit.

64e3bd481e Fix unprotected access to QDBusPendingCallPrivate::pending.
In QDBusConnectionPrivate::waitForFinished() pcall->pending was used
after the protection by pcall->mutex was released. A simultaneous
call to QDBusConnectionPrivate::processFinishedCall() was able
to reset pcall->pending to null before it was used for the
q_dbus_pending_call_block(pcall->pending) call.

Fixed by releasing (and setting to 0) of pcall->pending in
processFinishedCall() only in case no one is waiting yet, otherwise
release pcall->pending by the first thread waiting in waitForFinished().

There is still a race condition about deleting QDBusPendingCallPrivate
(too early) which will be fixed in the next two commits.
