QTcpServer problem receiving big files

[ruben.rodrigues]

Do you read the data from the socket anywhere?

yes, right after.

QDataStream in(tcpSocket);
in.setVersion(QDataStream::Qt_4_5);
 
forever {
	if (nextBlockSize == 0){
		if (tcpSocket->bytesAvailable() < sizeof (qint64))
			break;
		in >> nextBlockSize;
		cout << "Block size: " << QString::number(nextBlockSize).toStdString() << endl;
	}
 
	if (tcpSocket->bytesAvailable() < nextBlockSize)
	{
		cout << "Going to break" << endl;
		break;
	}
 
	in >> _applicationCall;
	in >> _classCall;
	in >> _methodCall;
	in >> _eBusinessObject;
        in >> qba;
}

QDataStream in(tcpSocket);
in.setVersion(QDataStream::Qt_4_5);

forever {
	if (nextBlockSize == 0){
		if (tcpSocket->bytesAvailable() < sizeof (qint64))
			break;
		in >> nextBlockSize;
		cout << "Block size: " << QString::number(nextBlockSize).toStdString() << endl;
	}

	if (tcpSocket->bytesAvailable() < nextBlockSize)
	{
		cout << "Going to break" << endl;
		break;
	}

	in >> _applicationCall;
	in >> _classCall;
	in >> _methodCall;
	in >> _eBusinessObject;
        in >> qba;
}

To copy to clipboard, switch view to plain text mode 

and this works if the qba (QByteArray) is small but when it's large like the one I want to store the server stops. Probably it waits until it receives data = 31525678435008617 bytes which means forever.
