for f in oci oci-rootless containerd containerd-1.0; do TESTFLAGS="--run //worker=$f\$ -v" ./hack/test integration; done succeeds but ./hack/test integration hangs.

Seems something is not working when multiple workers are simultaneously being tested.

AkihiroSuda · 2019-04-14T09:15:40Z

Even with multiple workers, the test suite passes after commenting out some testcases in client_test.go.

I assume we are hitting some quota (FD?) when we have lots of testcases/workers running.

0cc96a1 once succeeded but failed after restarting CI. Locally always fails.

@@ -111,6 +111,7 @@ func (c *conn) Close() (err error) {
 			err = c.stream.RecvMsg(m)
 			if err != nil {

This was the cause of the failure.

CI now passing 🎉

@tonistiigi @thaJeztah PTAL

I think you could equivalently have moved the existing Unlock() to a defer next to the Lock()?
