Description

I had a working setup using jupyter-server 1.12.1, in which jupyter lab was working with Python, R, and Julia kernels. I just checked today that when just updating in this setup jupyter-server from 1.12.1 to 1.13.0 makes jupyter lab fail with timeout when connecting to the R and Julia kernels. Python works.

Reproduce

  1. execute on terminal prompt "jupyter lab"
  2. use the GUI in the browser to create a new notebook (File -> New -> Notebook)
  3. select "R" kernel
  4. wait
  5. on the terminal the log ends with "tornado.util.TimeoutError: Timeout"
  6. the notebook on the browser does not execute any command

R and Julia notebooks do not even start on jupyter lab.

Expected behavior

R and Julia notebooks should work on jupyter lab.

Context

  • Operating System and version: Linux Fedora 34
  • Browser and version: google-chrome-stable-96.0.4664.93-1.x86_64
  • Jupyter Server version: 1.13.0

Hi @alusiani - could you please provide the server console's output after reproducing the issue with DEBUG logging enabled (just add --debug to the server start command)?

The nudge timeouts suggest that the server has not received the response from the kernel for its kernel-info-request. It's also odd that we see 3 nudge warnings for each logging period (every 10 attempts) and I'm hoping the debug logging might shed some light on that as well.

Hi,

here is the log with the --debug option:

Thank you. I'm guessing this is related to #628 and that the R and Julia kernels only deal with the shell channel for kernel-info requests.

Also curious about the 3 (separate) nudge loggings per attempt.

Having the same issue with Julia.

Python and SageMath work fine in JupyterLab, but Julia does not.

Julia does work in Jupyter Notebook however.

This is in Arch Linux.

@kevin-bates thanks for pinging me on this, you're absolutely right, kernels should handle th kernel_info_request on both channels now (and remove it form the shell when jupyter/enhancement-proposals#82 has been accepted.

@alusiani For the R kernel, the handler of kernel_info should be added here.

Does it mean that all kernels are now essentially broken until updated? That would break experience of many, many kernels which are not currently maintained. Would it be possible to make it optional until the JEP is accepted?

I would actually be in favor of "fixing" the different kernels (meaning they can handle kernel_info requests on both shell and control for now), we will have to do so at some point, so why not starting now?

There are many kernels: https://gist.github.com/chronitis/682c4e0d9f663e85e3d87e97cd7d1624 and these are only the ones we know about. My preference would be that such breaking changes should happen in a major version with a prior warning to give kernels time to migrate.

Would it be possible to fallback to shell channel for now if there is no reply on control channel?

Yes, I will implement that.
