2021-11-26Reimplement Que with ServantBen Sima
Still todo: add authentication. But that can wait. In re-implementing this, I was able to figure out how to get the Go.mult working properly as well. The problem is that a tap from a mult channel does not remove the message from the original channel. I'm not sure if that should be a core feature or not; for now I'm just draining the channel when it's received in the Que HTTP handler. (Also, this would be a good place to put persistence: have a background job read from the original channel, and write the msg to disk via acid-state; this would obviate the need for a flush to nowhere.) Also, streaming is working now. The problem was that Scotty closes the connection after it sees a newline in the body, or something, so streaming over Scotty doesn't actually work. It's fine, Servant is better anyway.
