Example 1 with StreamClosedException

use of tech.pegasys.teku.networking.p2p.rpc.StreamClosedException in project teku by ConsenSys.

the class BeaconBlocksByRootMessageHandlerTest method onIncomingMessage_interruptedByClosedStream.

@ParameterizedTest(name = "protocol={0}")
@MethodSource("protocolIdParams")
public void onIncomingMessage_interruptedByClosedStream(final String protocolId) {
    final List<SignedBeaconBlock> blocks = buildChain(5);
    // Mock callback to appear to be closed
    doThrow(new StreamClosedException()).when(callback).respond(any());
    final BeaconBlocksByRootRequestMessage message = createRequest(blocks);
    handler.onIncomingMessage(protocolId, peer, message, callback);
    // Check that we only asked for the first block
    verify(store, times(1)).retrieveSignedBlock(any());
    verify(callback, times(1)).respond(any());
}

Example 2 with StreamClosedException

use of tech.pegasys.teku.networking.p2p.rpc.StreamClosedException in project teku by ConsenSys.

the class BeaconBlocksByRangeMessageHandler method onIncomingMessage.

@Override
