Grizzly provider TimeoutException making async requests

[jbrittain]

When making async requests using the Grizzly provider (from AHC 2.0.0-SNAPSHOT), I get some TimeoutExceptions that should not occur. The server is serving these requests very rapidly, and the JVM isn't GCing very much. The requests serve in a fraction of a second, but the Grizzly provider says they timed out after 9 seconds. If I set the Grizzly provider's timeout to a higher number of seconds then it times out after that many seconds instead..

Some stack trace examples:

Here's what my asyncWarmup() method looks like:

public void asyncWarmup(final String testUrl) {
    List<Future<Response>> futures = new ArrayList<Future<Response>>(warmupRequests);
    for (int i = 0; i < warmupRequests; i++) {
        try {
            futures.add(this.client.prepareGet(testUrl).execute());
        } catch (IOException e) {
            System.err.println("Failed to execute get at iteration #" + i);
        }
    }

    for (Future<Response> future : futures) {
        try {
            future.get();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }
    }
}

And here's how the client is initialized:

@Override
protected void setup() {
    super.setup();

    GrizzlyAsyncHttpProviderConfig providerConfig = new GrizzlyAsyncHttpProviderConfig();
    AsyncHttpClientConfig config = new AsyncHttpClientConfig.Builder()
            .setAsyncHttpClientProviderConfig(providerConfig)
            .setMaximumConnectionsTotal(-1)
            .setMaximumConnectionsPerHost(4500)
            .setCompressionEnabled(false)
            .setAllowPoolingConnection(true /* keep-alive connection */)
            // .setAllowPoolingConnection(false /* no keep-alive connection */)
            .setConnectionTimeoutInMs(9000).setRequestTimeoutInMs(9000)
            .setIdleConnectionInPoolTimeoutInMs(3000).build();

    this.client = new AsyncHttpClient(new GrizzlyAsyncHttpProvider(config), config);

}

[rlubke]

Investigating now...

[rlubke]

Root cause is the request-in-flight idle timeout is being triggered when a connection is idle within the pool.

Good catch and thanks for logging the issue.

[jbrittain]

Interesting. Just so it's clear: when the connection is currently not being used for a request (so it's sitting in a pool of available connections), that's when the idle timeout is getting called?

Thanks for looking into it. I believe the Netty provider may have the same problem.

[rlubke]

Well, that's one part of it. The wrong timeout is being called, but digging more, it's actually not the root cause. Will be getting back to investigating this morning,

[rlubke]

Okay cleaned the code that would yield some false positives. That said, the issue persisted however, I believe I've finally narrowed the problem down.

The same test case doesn't fail with the Netty provider and this appears to be due to the fact that, by default, netty doesn't do async connections where as Grizzly does. If I enable async connections on the Netty provider, then I see the same result as with the Grizzly provider.

I'll be making some changes shortly to support configurable connection behavior.

[rlubke]

Mind pulling the latest updates from Master and verifying resolution on your end?

[jbrittain]

Sure, I'm trying it now..

[jbrittain]

It doesn't build.. looks like you need to change:

providers/netty/src/test/java/org/asynchttpclient/providers/netty/RetryNonBlockingIssue.java

from:
config.setAsyncConnect(true);

to:
bc.setAsyncConnectMode(true);

[rlubke]

Fixed, thanks.

...

I can give you a copy of the oome-heap-dump.hprof file if you'd like (if so, how?). I'm going to inspect it as well..

[rlubke]

Interesting. I'd recommend using something like dropbox to share the dump.
