I'm porting a TCP/IP client from wxWdigets to Qt. I've tried this under both
5.4.2 and 5.6.2.
I have a user-configured timeout value for network reads. The default is 300
seconds (5 minutes). I am feeding that to QTcpSocket::waitForReadyRead(), and
it's basically ignoring--worse, it's generating an error. It doesn't seem to
matter if it's 300,000 msecs or 3,000,000 msecs, I get "Network operation
timed out" (5) returned from it.
int msecs = timeout * 1000000;
if(!socket.waitForReadyRead(msecs))
{
QString msg = QString(tr("An error occurred while receiving data
from the server: \"%1\" (%2).")).arg(socket.errorString()).arg(socket.error());
...
This causes the communications to fail, even though the action takes place
pretty much instantly, because I'm running the server on the same machine for
testing/debugging. If I tell QTcpSocket::waitForReadyRead() to wait forever:
if(!socket.waitForReadyRead(-1))
everything runs smoothly.
I've done nothing with the QTcpSocket instance in terms of configuration. I
just create it, and then start the ball rolling with a call to
connectToHost(). Have I not configured some Qt5-thing correctly?
