Support configuration of WebSocket's "max_queue"

[ssproessig-thales]

Currently, uvicorn supports configuring WebSocket's max_size using Config.ws_max_size.

I'd be interested in configuring max_queue as well, e.g. via ws_max_queue.

I did not find any way to change the built-in default of 2**5=32 that is set for the default value in WebSocketCommonProtocol.__init__ otherwise.

Would this be an ok idea? Or are there maybe problems?

I don't know. Does wsproto also allows that configuration?

Didn't see any queue in their code. Seems like they use generators and yield events out directly

• https://github.com/python-hyper/wsproto/blob/main/src/wsproto/frame_protocol.py#L568C28-L568C28
• https://github.com/python-hyper/wsproto/blob/main/src/wsproto/connection.py#L150
• https://github.com/python-hyper/wsproto/blob/main/src/wsproto/frame_protocol.py#L502

Looks like the raw socket buffer is used directly.

I never used wsproto, though.

Would be a websockets only option (as max_size, isn't it?)...

yep, since we already have max_size, then we can have max_queue as well.
