Example 21 with ClientException

use of com.netflix.client.ClientException in project ribbon by Netflix.

the class NettyClientTest method testLoadBalancerThrottle.

@Test
public void testLoadBalancerThrottle() throws Exception {
    HttpClientRequest<ByteBuf> request = HttpClientRequest.createGet("/testAsync/throttle");
    IClientConfig config = DefaultClientConfigImpl.getClientConfigWithDefaultValues().set(IClientConfigKey.Keys.MaxAutoRetriesNextServer, 1).set(IClientConfigKey.Keys.OkToRetryOnAllOperations, true);
    BaseLoadBalancer lb = new BaseLoadBalancer(new DummyPing(), new AvailabilityFilteringRule());
    LoadBalancingHttpClient<ByteBuf, ByteBuf> lbObservables = RibbonTransport.newHttpClient(lb, config);
    Server server = new Server(host, port);
    lb.setServersList(Lists.newArrayList(server, server, server));
    Observable<HttpClientResponse<ByteBuf>> response = lbObservables.submit(request);
    final CountDownLatch latch = new CountDownLatch(1);
    final AtomicReference<Throwable> error = new AtomicReference<Throwable>();
    response.subscribe(new Action1<HttpClientResponse<ByteBuf>>() {

        @Override
        public void call(HttpClientResponse<ByteBuf> t1) {
            System.err.println("Get response: " + t1.getStatus().code());
            latch.countDown();
        }
    }, new Action1<Throwable>() {

        @Override
        public void call(Throwable t1) {
            error.set(t1);
            latch.countDown();
        }
    }, new Action0() {

        @Override
        public void call() {
            Thread.dumpStack();
            latch.countDown();
        }
    });
    latch.await();
    assertTrue(error.get() instanceof ClientException);
    ClientException ce = (ClientException) error.get();
    assertTrue(ce.toString(), ce.getErrorType() == ClientException.ErrorType.NUMBEROF_RETRIES_NEXTSERVER_EXCEEDED);
    assertEquals(2, lbObservables.getServerStats(server).getSuccessiveConnectionFailureCount());
}

Example 22 with ClientException

use of com.netflix.client.ClientException in project feign by OpenFeign.

the class RibbonClient method execute.

@Override

    try {
        URI asUri = URI.create(request.url());
        String clientName = asUri.getHost();

        LBClient.RibbonRequest ribbonRequest = new LBClient.RibbonRequest(delegate, request, uriWithoutHost);
        return lbClient(clientName).executeWithLoadBalancer(ribbonRequest, new FeignOptionsClientConfig(options)).toResponse();
    } catch (ClientException e) {
        propagateFirstIOException(e);
        throw new RuntimeException(e);
    }
}

Example 23 with ClientException

use of com.netflix.client.ClientException in project feign by OpenFeign.

the class PropagateFirstIOExceptionTest method propagatesDoubleNestedIOE.

/**
   * Happened in practice; a blocking observable wrapped the connect exception in a runtime
   * exception
   */
@Test

    thrown.expect(ConnectException.class);
    RibbonClient.propagateFirstIOException(new ClientException(new RuntimeException(new ConnectException())));
}
