Affects Version/s: 5.2-alpha1
5.1.3
(was: 5.2-alpha1)
Workflow: Default workflow, editable Closed status (was: classic
default workflow)
Project: HttpComponents HttpClient (was: HttpComponents HttpCore)
> AsyncClientEndpoint is not released upon lease failure

> Key: HTTPCLIENT-2212
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2212
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (async)
> Affects Versions: 5.2-alpha1, 5.1.3
> Reporter: Lubos Husivarga
> Priority: Major
>
> When I use AsyncHttpClient and try to lease an endpoint to host
> "https://localhost";, I receive javax.net.ssl.SSLHandshakeException exception
> via callback's failed method. That's ok, because my localhost certificate is
> not signed by authority.
> The strange thing is that the endpoint is allocated from
> PoolingAsyncClientConnectionManager, but not released after the connection
> failure during the endpoint lease operation.
> There is no way to release the endpoint from callback failed method, because
> there is no reference to it.
> Failing the lease multiple times consumes all available connections from
> connection manager pool and any further lease operation remains in pending
> state preventing any other connections to the host.
> example:
>
> {code:java}
> httpManager = PoolingAsyncClientConnectionManagerBuilder.create()
> .setDefaultConnectionConfig(ConnectionConfig.custom()
> .setTimeToLive(TimeValue.NEG_ONE_MILLISECOND) //TTL is
> maximum time one connection can be used,
> //then it is closed and new one is opened. Therefore
> -1 disables TTL and same connection lasts until
> //it is actively used. Then closed by
> IdleConnectionEvictor thread.
> .build())
> .setDefaultTlsConfig(TlsConfig.custom()
> .setVersionPolicy(HttpVersionPolicy.NEGOTIATE)
> .build())
> .build();
> httpClient = HttpAsyncClients.createMinimal(
> H2Config.DEFAULT,
> Http1Config.DEFAULT,
> IOReactorConfig.DEFAULT,
> httpManager);
> httpClient.start();
>
> HttpHost host = new HttpHost("https", "localhost", 443);
> httpClient.lease(host, new FutureCallback<AsyncClientEndpoint>() {
> @Override
> public void failed(Exception ex) {
> }
>
> @Override
> public void completed(AsyncClientEndpoint result)
> {
> }
>
> @Override
> public void cancelled() {
> }
> });
>
> Set<HttpRoute> routes = httpManager.getRoutes();
> List<RouteStats> stats = new ArrayList<RouteStats>(routes.size());
>
> for(HttpRoute route : routes){
> PoolStats s = httpManager.getStats(route);
> System.out.println(route.getTargetHost().getHostName());
> System.out.println(s.getAvailable());
> System.out.println(s.getLeased());
> System.out.println(s.getMax());
> System.out.println(s.getPending());
> }
> {code}
