zmq.Poller is not async #1022

Closed fcollonval closed 2 months ago

fcollonval commented 2 months ago

The line https://github.com/jupyter/jupyter_client/blob/0a19278ed8d4090080a44760498a38ad9d4e0d99/jupyter_client/client.py#L533 makes the code blocking.

We should use zmq.asyncio.Poller.

Seen when working on https://github.com/datalayer/jupyter-server-nbmodel, when manually testing the code, jupyter-server requests are blocked.
