[Development] QThread usage/guidance

[Tony Van Eerd]

What was the final resolution (if any) of  the email thread "QThread::finished() race → fixing QThread"
http://lists.qt-project.org/pipermail/development/2011-November/000284.html


In particular as seen in http://mayaposch.wordpress.com/2011/11/01/how-to-really-truly-use-qthreads-the-full-explanation/

                worker->moveToThread(thread);
                connect(worker, SIGNAL(error(QString)), this, SLOT(errorString(QString)));
                connect(thread, SIGNAL(started()), worker, SLOT(process()));
                connect(worker, SIGNAL(finished()), thread, SLOT(quit()));
                connect(worker, SIGNAL(finished()), worker, SLOT(deleteLater()));
                connect(thread, SIGNAL(finished()), thread, SLOT(deleteLater()));

Is there a race where the worker deleteLater() doesn't happen due to the thread having already finished?

I'm trying to provide guidance to teams on QThread usage...
