Controller
’s port to which all
Player

akka.remote.testconductor.NetworkFailureInjector
and provides support
for barriers using the BarrierCoordinator
.
All of this is bundled inside the TestConductorExt
extension.Modifier and Type | Method and Description |
---|---|
scala.concurrent.Future<Done> |
abort(RoleName node,
RoleName target)
Tell the remote support to TCP_RESET the connection to the given remote
peer.
|
scala.concurrent.Future<Done> |
blackhole(RoleName node,
RoleName target,
ThrottlerTransportAdapter.Direction direction)
Switch the Netty pipeline of the remote support into blackhole mode for
sending and/or receiving: it will just drop all messages right before
submitting them to the Socket or right after receiving them from the
Socket.
|
ActorRef |
controller() |
scala.concurrent.Future<Done> |
disconnect(RoleName node,
RoleName target)
Tell the remote support to shutdown the connection to the given remote
peer.
|
scala.concurrent.Future<Done> |
exit(RoleName node,
int exitValue)
Tell the remote node to shut itself down using System.exit with the given
exitValue.
|
scala.concurrent.Future<scala.collection.Iterable<RoleName>> |
getNodes()
Obtain the list of remote host names currently registered.
|
scala.concurrent.Future<Done> |
passThrough(RoleName node,
RoleName target,
ThrottlerTransportAdapter.Direction direction)
Switch the Netty pipeline of the remote support into pass through mode for
sending and/or receiving.
|
scala.concurrent.Future<Done> |
removeNode(RoleName node)
Remove a remote host from the list, so that the remaining nodes may still
pass subsequent barriers.
|
void |
requireTestConductorTranport() |
scala.concurrent.Future<Done> |
shutdown(RoleName node)
Tell the actor system at the remote node to shut itself down.
|
scala.concurrent.Future<Done> |
shutdown(RoleName node,
boolean abort)
Tell the actor system at the remote node to shut itself down without
awaiting termination of remote-deployed children.
|
scala.concurrent.Future<java.net.InetSocketAddress> |
sockAddr()
Obtain the port to which the controller’s socket is actually bound.
|
scala.concurrent.Future<java.net.InetSocketAddress> |
startController(int participants,
RoleName name,
java.net.InetSocketAddress controllerPort)
Start the
Controller , which in turn will
bind to a TCP port as specified in the akka.testconductor.port config
property, where 0 denotes automatic allocation. |
scala.concurrent.Future<Done> |
throttle(RoleName node,
RoleName target,
ThrottlerTransportAdapter.Direction direction,
double rateMBit)
Make the remoting pipeline on the node throttle data sent to or received
from the given remote peer.

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 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.

(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.
