Fields

• acceptorTracer :: !(Tracer IO (TraceSendRecv (TraceObjectForward lo)))

  The tracer that will be used by the acceptor in its network layer.

• forwarderEndpoint :: !FilePath

  The endpoint that will be used to listen to the forwarder. Only local socket/pipe is supported.

• whatToRequest :: !NumberOfTraceObjects

  The request specifies how many TraceObjects will be requested.

• shouldWeStop :: !(TVar Bool)

  TVar that can be used as a brake: if an external thread sets it to True, the acceptor will send MsgDone message to the forwarder and their session will be closed.

Fields

• forwarderTracer :: !(Tracer IO (TraceSendRecv (TraceObjectForward lo)))

  The tracer that will be used by the forwarder in its network layer.

• acceptorEndpoint :: !FilePath

  The endpoint that will be used to connect to the acceptor. Only local socket/pipe is supported.

• disconnectedQueueSize :: !Word

  The big size of internal queue for tracing items. We use it in the beginning of the session, to avoid queue overflow, because initially there is no connection with acceptor yet, and the number of tracing items after node's start may be very big.

• connectedQueueSize :: !Word

  The small size of internal queue for tracing items. We use it after the big queue is empty, which means that acceptor is connected and tracing items are already forwarded to it. We switch to small queue to reduce memory usage in the node.
