trait Conductor extends AnyRef

The conductor is the one orchestrating the test: it governs the akka.remote.testconductor.Controller’s port to which all akka.remote.testconductor.Players connect, it issues commands to their akka.remote.testconductor.NetworkFailureInjector and provides support for barriers using the akka.remote.testconductor.BarrierCoordinator. All of this is bundled inside the akka.remote.testconductor.TestConductorExt extension.

  26. def removeNode(node: RoleName): Future[Done]

    Remove a remote host from the list, so that the remaining nodes may still pass subsequent barriers.

    Remove a remote host from the list, so that the remaining nodes may still pass subsequent barriers. This must be done before the client connection breaks down in order to affect an “orderly” removal (i.e. without failing present and future barriers).

    node

    is the symbolic name of the node which is to be removed

  27. def shutdown(node: RoleName, abort: Boolean): Future[Done]

    Tell the actor system at the remote node to shut itself down without awaiting termination of remote-deployed children.

  29. def sockAddr: Future[InetSocketAddress]

    Obtain the port to which the controller’s socket is actually bound.

    Obtain the port to which the controller’s socket is actually bound. This will deviate from the configuration in akka.testconductor.port in case that was given as zero.

  30. def startController(participants: Int, name: RoleName, controllerPort: InetSocketAddress): Future[InetSocketAddress]

    Start the akka.remote.testconductor.Controller, which in turn will bind to a TCP port as specified in the akka.testconductor.port config property, where 0 denotes automatic allocation.

    Start the akka.remote.testconductor.Controller, which in turn will bind to a TCP port as specified in the akka.testconductor.port config property, where 0 denotes automatic allocation. Since the latter is actually preferred, a Future[Int] is returned which will be completed with the port number actually chosen, so that this can then be communicated to the players for their proper start-up.

    This method also invokes akka.remote.testconductor.Player.startClient, since it is expected that the conductor participates in barriers for overall coordination. The returned Future will only be completed once the client’s start-up finishes, which in fact waits for all other players to connect.

    participants

    gives the number of participants which shall connect before any of their startClient() operations complete.

  3. def throttle(node: RoleName, target: RoleName, direction: Direction, rateMBit: Double): Future[Done]

    Make the remoting pipeline on the node throttle data sent to or received from the given remote peer.

    Make the remoting pipeline on the node throttle data sent to or received from the given remote peer. Throttling works by delaying packet submission within the netty pipeline until the packet would have been completely sent according to the given rate, the previous packet completion and the current packet length. In case of large packets they are split up if the calculated send pause would exceed akka.testconductor.packet-split-threshold (roughly). All of this uses the system’s scheduler, which is not terribly precise and will execute tasks later than they are schedule (even on average), but that is countered by using the actual execution time for determining how much to send, leading to the correct output rate, but with increased latency.

    Note

    To use this feature you must activate the failure injector and throttler transport adapters by specifying testTransport(on = true) in your MultiNodeConfig.

    node

    is the symbolic name of the node which is to be affected

    target

    is the symbolic name of the other node to which connectivity shall be throttled

    direction

    can be either Direction.Send, Direction.Receive or Direction.Both

    rateMBit

    is the maximum data rate in MBit
