You can still receive messages from disconnected users
ekimekim opened this issue · comments
When a user is disconnected, several messages from them may have already been received (but not processed yet). This can create situations where messages from disconnected users are processed. This can cause many Bad Things, most notably:
- A channel can receive a message from a user that isn't connected. I've observed this in practice, where the client sees a QUIT for a user, followed by a message from them.
- Certain internal actions which assume the user is in
ircd.userswill fail, including a second attempt at disconnect.
I propose simply adding a check to user.dataReceived that ignores any data once the user is disconnected.
Fixed
