LGTM, could you add a unit test for this behavior?
The `Http2Session#request()` method internally listens to the "connect" event if the session has not yet established a connection so that the actual request can be sent after the connection has been established. This commit removes the event listener after it runs and carries out the request and is no longer needed. In practice this shouldn't affect the behavior of the session object since the "connect" event fires only once anyway, but removing the listener releases its references. The rest of this class subscribes to the "connect" event with `once` instead of `on` as well. Tested by adding a new test that ensures `Http2Session#request()` is called before the connection is established, indicated by a "connect" listener that is run. The test also ensures all "connect" listeners are removed after the connection is established.
@mcollina Thanks for reviewing. I added a unit test that fails without this commit and passes with it. |
