Drop messages where channel does not exist - #914
Merged
Merged
Conversation
At the moment, if a message is received and a channel does not exist the channel is created (via channels.get) to process the message. This can lead to issues with channels.release, which also detaches the channel after removing it from the channel map. If the timing is unfortunate, then the DETACH message will come back and re-create the channel, meaning it cannot be recreated afresh later. This change fixes the issues by dropping any messages that are received for a non existent channel and logs the fact that this has happened. Fixes #913

Code looks good overall. I have made some requests that will hopefully improve the code.
