* Do not wait in QWindowsPipe{Reader|Writer}::stop()Joerg Bornemann2017-07-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | A deadlock can occur if the user does QLocalSocket *ls = new QLocalSocket; ls->moveToThread(t); ... delete ls; Then QLocalSocket calls QWindowsPipeReader::stop() in a different thread than the I/O operation is running in. The waitForNotified(-1) call would then wait indefinitely until the I/O thread is in alertable wait state again. Especially on application shut down this might never be the case, and the application would deadlock. Solve this by detaching the Overlapped object from the QWindowsPipe{Reader|Writer} in stop() and delete it in the callback.

| * Rework QWindowsPipeReaderJoerg Bornemann2016-03-171-12/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The use of QWinOverlappedIoNotifier in QWindowsPipeReader restricts us in the following ways: - The handle that gets assigned to QWinOverlappedIoNotifier is forever tied to an I/O completion port. - Other notification mechanisms like I/O completion routines of WriteFileEx do not work with such a handle. - No other QWinOverlappedIoNotifier can be registered for this handle. To achieve the ultimate goal of making QWindowsPipeWriter thread-free (to fix QTBUG-23378 and QTBUG-38185) we remove the usage of QWinOverlappedIoNotifier from QWindowsPipeReader and use the ReadFileEx API instead. This has the additional advantage of removing the need for any thread synchronization, as the I/O completion routine runs in the thread that ReadFileEx was called on, leading to simpler and faster code.

| | * let QWindowsPipeReader::stop() cancel the current I/O operationJoerg Bornemann2015-04-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In rare cases the I/O operation was still running after the destructor was running, which then modified free'd memory and caused a malformed heap. To prevent this, we ensure that QWindowsPipeReader::stop() cancels a running I/O operation and sets the readSequenceStarted flag correctly. Also, we prevent the start of a new read operation after we called stop().

| | * remove emitReadyReadTimer from QWindowsPipeReaderJoerg Bornemann2015-04-161-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The zero timeout singleshot timer emitReadyReadTimer was used to emit the readyRead signal via the event loop in case of a synchronous read. In that particular case, ReadFile would return successfully, and the notified slot would not be called. Now, that we use an I/O completion port, the notified slot is always called, even in the synchronous case. The emitReadyReadTimer is not needed anymore. This is also supported by the fact that the timer is immediately stopped in notified() after it was started in completeAsyncRead().
