Hello -
I have migrated to akka-streams 2.4.4 from 1.0. The following snippet of
code (part of a larger application) used to work properly in 1.0 but fails
in 2.4.4 ..
def run(): Unit = {
implicit val mat = ActorMaterializer()
val summarizer = system.actorOf(Props[Summarizer])
logger.info(s"Receiver: binding to $host:$port")
Tcp().bind(host, port).runForeach { conn =>
val receiveSink =
conn.flow
.via(Framing.delimiter(ByteString("\n"), maximumFrameLength =
4000, allowTruncation = true)).map(_.utf8String)
.map(_.split(","))
.mapConcat(Transaction(_).toList)
.to(Sink.fromSubscriber(ActorSubscriber[Transaction](summarizer)))
Source.empty.to(receiveSink).run() // ##
}
import system.dispatcher
system.scheduler.schedule(0.seconds, 30.seconds, summarizer,
LogSummaryBalance)
}
The problem is in the line marked // ##. When the client connects to this
service, I get different types of errors every time .. e.g. Broken Pipe,
Connection reset by peer etc. May be some race condition as the errors
differ every time.
Do I need to do anything different for the new version ?
Any help ?
Thanks.
