Example 6 with HttpClientListener

use of io.reactivex.netty.servo.http.HttpClientListener in project ribbon by Netflix.

the class NettyClientTest method testLoadBalancingObservablesWithReadTimeout.

@Test
public void testLoadBalancingObservablesWithReadTimeout() throws Exception {
    NettyHttpLoadBalancerErrorHandler errorHandler = new NettyHttpLoadBalancerErrorHandler(1, 3, true);
    MockWebServer server = new MockWebServer();
    String content = "{\"name\": \"ribbon\", \"age\": 2}";
    server.enqueue(new MockResponse().setResponseCode(200).setHeader("Content-type", "application/json").setBody(content));
    server.play();
    IClientConfig config = DefaultClientConfigImpl.getClientConfigWithDefaultValues().set(CommonClientConfigKey.ReadTimeout, 100);
    HttpClientRequest<ByteBuf> request = HttpClientRequest.createGet("/testAsync/readTimeout");
    BaseLoadBalancer lb = new BaseLoadBalancer(new DummyPing(), new AvailabilityFilteringRule());
    LoadBalancingHttpClient<ByteBuf, ByteBuf> lbObservables = RibbonTransport.newHttpClient(lb, config, errorHandler);
    Server goodServer = new Server("localhost:" + server.getPort());
    Server badServer = new Server("localhost:" + port);
    lb.setServersList(Lists.newArrayList(goodServer, badServer, badServer, goodServer));
    Observable<Person> observableWithRetries = getPersonObservable(lbObservables.submit(request));
    ObserverWithLatch<Person> observer = new ObserverWithLatch<Person>();
    observableWithRetries.subscribe(observer);
    observer.await();
    if (observer.error != null) {
        observer.error.printStackTrace();
    }
    assertEquals("ribbon", observer.obj.name);
    assertEquals(2, observer.obj.age);
    ServerStats stats = lbObservables.getServerStats(badServer);
    server.shutdown();
    final HttpClientListener listener = lbObservables.getListener();
    waitUntilTrueOrTimeout(1000, new Func0<Boolean>() {

        @Override
        public Boolean call() {
            return listener.getPoolReleases() == 5;
        }
    });
    assertEquals(0, listener.getPoolReuse());
    // two requests to bad server because retry same server is set to 1
    assertEquals(4, stats.getTotalRequestsCount());
    assertEquals(0, stats.getActiveRequestsCount());
    assertEquals(4, stats.getSuccessiveConnectionFailureCount());
    stats = lbObservables.getServerStats(goodServer);
    assertEquals(1, stats.getTotalRequestsCount());

Example 7 with HttpClientListener

use of io.reactivex.netty.servo.http.HttpClientListener in project ribbon by Netflix.

the class NettyClientTest method testPoolReuse.

@Test
public void testPoolReuse() throws Exception {
    HttpClientRequest<ByteBuf> request = HttpClientRequest.createGet(SERVICE_URI + "testAsync/person");
    LoadBalancingHttpClient<ByteBuf, ByteBuf> observableClient = RibbonTransport.newHttpClient(IClientConfig.Builder.newBuilder().withDefaultValues().withMaxAutoRetries(1).withMaxAutoRetriesNextServer(1).build());
    Observable<HttpClientResponse<ByteBuf>> response = observableClient.submit(request);
    Person person = getPersonObservable(response).toBlocking().single();
    assertEquals(EmbeddedResources.defaultPerson, person);
    response = observableClient.submit(request);
    person = getPersonObservable(response).toBlocking().single();
    assertEquals(EmbeddedResources.defaultPerson, person);
    final HttpClientListener listener = observableClient.getListener();
    assertEquals(2, listener.getPoolAcquires());
    waitUntilTrueOrTimeout(1000, new Func0<Boolean>() {

        @Override
        public Boolean call() {
            return listener.getPoolReleases() == 2;
        }
    });
    assertEquals(1, listener.getConnectionCount());
    assertEquals(1, listener.getPoolReuse());
