Hello!
My server side:
def update: Iterator[ByteString]
lazy val binding = StreamTcp(system).bind(address, idleTimeout =
20.seconds)
def start(): Future[Unit] = {
val firstCompleted = Promise[Unit]()
val foreachConnection = ForeachSink[IncomingConnection] {
connection =>
val handleConnection = FlowGraph { implicit b =>
import akka.stream.scaladsl.FlowGraphImplicits._
val updateSource = Source[ByteString](() => update)
val broadcast = Broadcast[ByteString]
updateSource ~> broadcast
broadcast ~> connection.flow ~> BlackholeSink
broadcast ~> OnCompleteSink[ByteString] { res =>
firstCompleted.complete(res)
}
}
handleConnection.run()
}
val connectionsMap = binding.connections.to(foreachConnection).run()
firstCompleted.future.flatMap {_ => binding.unbind(connectionsMap)}
.recoverWith { case ex => binding.unbind(connectionsMap).flatMap(_ =>
{
Future.failed(ex)
})}
}
If i have exception on the client side, this future will be completed with
Success anyway. Is there a way to handle tcp exceptions (client disconect
for example) ?
