Motivation: As described in #5734 Before this change, if the server had to do some sort of setup after a handshake was completed based on handshake's information, the only way available was to wait (in a separate thread) for the handshaker to be added as an attribute to the channel. Too much hassle. Modifications: Handshake completed event need to be stateful now, so I've added a tiny class holding just the HTTP upgrade request and the selected subprotocol which is fired as an event after the handshake has finished. I've also deprecated the old enum used as stateless event and I left the code that fires it for backward compatibility. It should be removed in the next mayor release. Result: It should be much simpler now to do initialization stuff based on subprotocol or request headers on handshake completion. No asynchronous waiting needed anymore. |
