Hello,
I was playing around with Stream API 2.0 where I got a strange
error-message:
"Cannot materialize an incoming connection Flow twice.". I could track down
the issue to a code-line. So this what I am doing
Server code:
val connections = Tcp().bind(localHost.getHostName, port, backlog,
socketOptions, idleTimeout = 10.seconds)
connections.runForeach(handleConnnection(_))
where the handleConnection function spawns an Actor which setups a flow
like this:
conn.handleWith(getLogicalFlow())
Now I set some kind of timer that should close the connection (To prevent
long open TCP Connections that I for example got from a Loadbalancer I put
in front of my Server application). I did this with Akka Streaming 1.X like
this:
def closeConnection(connection: Tcp.IncomingConnection): Unit = {
implicit val materializer = ActorMaterializer()
// Handle connection with the closing Flow
connection.flow.runWith(Source.empty, Sink.cancelled)
}
I also tried:
connection.handleWith(Flow.fromSinkAndSource(Sink.cancelled, Source.empty))
But the problem seems like that I cannot change the flow as soon as it
materialized. Any good thoughts on how I could fix this?
Regards,
Thomas
