Agenda

• Darian

  • Executive Council + SSC update

• Steve

  • New minor release today? Adding JPY_SESSION_NAME
    • Will do this later today or next Monday
  • API docs PR - would appreciate a review to make sure I didn't accidentally break something
  • Cleaning up typings in jupyter_events.
  • Warning emitted by pyzmq 25: "zmq.eventloop.ioloop is deprecated in pyzmq 17" - Warning emitted by pyzmq 25: "zmq.eventloop.ioloop is deprecated in pyzmq 17" jupyter/jupyter_client#913

• Vidar

  • I expect this fails for synchronous contents managers, but I wasn't able to reproduce it locally. Has the jupyter_core code been updated to handle it? Do we need to bump lower version bound if so? https://github.com/jupyter-server/jupyter_server/blob/5cce2afcbeeb44581e9b29ab27fef75a12d651ca/jupyter_server/services/contents/manager.py#L82 -- MAINT: Coro is not coro-function. jupyter/jupyter_core#330
  • 1.x patch / minor release?
    • https://github.com/jupyter-server/jupyter_server/releases/tag/v1.23.5 released today,
    • 2.1 release planned today or next Monday

Agenda

• Steve

  • Only load enabled extension packages PR merged
  • Bug in preferred_dir affecting JupyterLab - ServerApp.preferred_dir wrongly set if root_dir is overwritten in extension app jupyter_server#1181

• Kevin

  • Custom entries in kernelspec model (resources stanza)
    • Will recommend application customizations be placed into the free-form metadata stanza that is located in the spec stanza.

• David Q

  • Async procedures in initialize_settings()?
    • run_sync utility function in jupyter_core
    • serverapp.io_loop.add_callback()
    • Future directions: make initialize_settings() and initialize_handlers() async and have a running event loop beforehands

• Johan

  • JEP for optional features - JEP for Optional Features jupyter/enhancement-proposals#92

• Vidar

  • Any note on how to generically support both jupyter_server 2 and notebook 6 as server extension? E.g. what is the best way to detect if we are being imported/loaded as a server 2.0 extension?
    • Force jupyter-server v1 to check against notebook v6 jupyterlab/jupyterlab#13716

Agenda

• Kevin:

  • Trailets question: Is it possible to configure traits on multiple instances of a class with different values for the various traits on each instance?
    • Not natively as they are class based. Some form of custom loader/configurator would be necessary.

• Piyush:

  • Bug bounty program: Participating in Security Bug Bounty program jupyterlab/frontends-team-compass#174
    • Should jupyter-server be included in this? Or, is jupyterlab testing going to cover that?
    • If yes, how should we track this?

• Steve

  • Going to release Jupyter Client 8 today. Should be no major user-facing changes, mostly internal cleanup around async handling.

• Vidar

  • If someone wants to take over this partial PR, I'd appreciate it: Use pydevd ipython hook ipython/ipykernel#1047
    • Johan mentioned he'd take a look (thanks Johan!)

Agenda

• Kevin:

  • New repo for gateway-provisioners
    • Zach will call a vote via the Server Council to determine if it will be moved.

• Zach

  • Security Bug Bounty Program
    • Decision by February 5th (Sunday)
    • What repositories should we have them review?
      • jupyter_server
      • enterprise_gateway
        • package_name: jupyter-enterprise-gateway
        • installation instructions
        • documentation
        • how to report issues: security@ipython.org or kbates4@gmail.com
      • jupyverse
      • jupyter_server_ydoc
      • ...?
      • Follow up with the Jupyter Standards group: jupyter-standards-council@googlegroups.com regarding inclusion of jupyter_client
    • Two things needed to proceed:
      • a representative to be the main point person to correspond with the bug bounty program.
      • a group of team members willing+able to review, verify, and respond to any reported bugs.
        • Kevin Bates, Jessica Xu, Andrii Ieroshenko
      • Piyush: Putting together a doc here

• Steve

  • 2.2 released with "Only load enabled extension packages"
  • Adopted more linting rules

Agenda

• Frederic:

  • jupyter-server v2 / notebook v6 issue
    It looks like it brings trouble even outside of the Binder usage.

  • Jupyter Server v2 on Binder: currently it requires two tricks

    • Use a start script to not use jupyter notebook as start application
    • Force upgrading Python to be Python 3.8 or above; the default image is using Python 3.7 that is no more supported since jupyter-server 2.0.0

    A gist to demonstrate a setup: https://gist.github.com/fcollonval/8a761e045dbf12f053f9c6bf1166cba8
    On Gitter, Jeremy explain how to use conda to bump Python: https://gitter.im/jupyterlab/jupyterlab?at=63e3adb8f4ead81aa367dd0f

• Darian: JVM kernels

• Johan: new C++ kernel
  https://github.com/compiler-research/xeus-clang-repl

• Zach: Add a post_start method to ExtensionApps

  • Does anyone see an issue with adding such a method?
    • Nothing raised during the meeting.
  • Add async post_start method to ExtensionApp jupyter_server#1203

Agenda

• Frederic

  • I want to point out the JupyterLab PR Upgrade to MathJax 3 - this will drop the usage of server config mathjax_config that for example is leverage by jupyter_server_mathjax. Is it a good or a bad change to drop that server configuration? Feel free to comment on the JupyterLab PR.

  We can move on with the PR. But as follow-up, JupyterLab team needs to release the older MathJax 2 extension independently (preferably in the jupyter-renderers). This is similar to vega management we have done.

• Zach

  • JS council: remember to vote on the gateway-provisioners proposal
  • 2.3.0 Released this past week with IPv6 support

• Jupyter Enhancement Proposals to begin reviewing:

  1. Parameterized kernel specs proposal
  2. Kernel sub-shells
  3. Kernel Handshaking pattern

[ellisonbg]

On the MathJax 2 extension. Is there a reason or signal why we need to support MathJax 2? MathJax 3 has been out for over 3 years, so it isn't clear that this is needed. Thoughts?

[ellisonbg]

ping @fcollonval on the MathJax 2 question.

[dlqqq]

^ On this note, the MathJax 2 extension will still be preserved in the JupyterLab 3.x branch, so it's not clear why it would need to be migrated to a separate repo; IMO it should only be maintained for as long as 3.x is maintained, so keeping it living in that branch seems sufficient.

[krassowski]

One of the points in discussion previously was that MathJax 3 does not support line breaking and we had a conversation about whether we should wait for it MathJax 4 which will support it here: jupyterlab/jupyterlab#7218 (comment).
