Agenda

• Frederic

  • 📣 Performance meeting after this one.

  • JupyterLab 3.6

    • Release Candidate 0 released a week ago.
    • Lots of CI failures fixed during the past week.
    • Missing PRs:
      • Enable creating widgets in shadow DOM
      • Added config to link ts source maps
      • Any other PRs? If not I will release the final version as soon as those are in.

  • JupyterLab 4.0 - GitHub project

    • Main api breaking changes missing:
      • CodeMirror 6 using tokens: in progress
        I was slowed down by CI maintenance.
      • RTC through IDrive: in progress
    • Lumino 2;
      • beta 0 released
      • Feature to discuss before Release Candidate regarding new feature introducing Shadow DOM in Widget optionally; linked PR

• David Q, Piyush, Jason W, Andrii: Jupyter Generative AI (GAI) proposal

  • 5-minute live demo
  • Proposal: Generative AI in Jupyter jupyterlab#13804
  • Vote: Package location for Generative AI in Jupyter #172

• @jasongrout: Possible security bug bounty program. Interested, if it pans out?

• Darian

  • LabIcon question: how do you create a LabIcon if you have the URL of an SVG, not its base64 string version?
    • <image> (Not sure this answers the question)
  • Swapping in alternate service manager?
    Allow the application service manager to be set by a plugin jupyterlab#13558
    • Nick Bollweg says that this wouldn't help JupyterLite, since JLite needs its own application anyway
    • Darian says that if this doesn't solve JupyterLite's use case, which normally would just be a clone of JupyterLab, then perhaps it's not worth the extra complexity this
    • but would love:
      • app.services.kernelspecs.addKernelspecProvider
      • app.services.kernels.addKernelProvider
      • data connector for settings?
      • these are akin to the codemirror mode finding

• Mike

  • timeline update for JupyterLab 4.0? 3.7 before or after?
    • Actions that cannot go in 4.x release that nobody is working on:
      • Bumping yarn
      • Bumping the JSON schema version used

Agenda

• Frederic

  • 📣 JupyterLab 3.5.3 released - highlight @jupyterlab/builder is not depending on verdaccio any longer (huge reduction of the dev dependencies)
  • JupyterLab 3.6.0:
    • Hopefully release this week
      • Blocking point: Expose contentVisibility widget hiding mode
        I'll move forward the feature on 3.6.x to release 3.6.0. The work to merge it in master will wait a bit (blocked by upgrade of Lumino 2 beta 1).
  • Move RTC package in jupyter_server_ydoc and move that repo in JupyterLab
    Follow-up open issue on the team compass
  • Security Bug Bounty Program - funded by the European Union
    • Who wants to be the contact point? [role is to monitoring that the process runs smoothly]
      • Piyush and David Q. are volunteer for being the contact point
      • Helpers for reviewing the security reports:
        • Mike
        • Frederic
        • Andrii
        • Piyush
        • David Q.
    • What target:
      • 3.x or 4.x?
      • jupyterlab, jupyterlab-server?
      • [mike] Should we target JLab desktop, jupyterlab-git,...
    • What they need:
      • At the beginning
        • How to install?
        • How to report? -> using GitHub CVE report
        • Point of contact person/people
      • During the hunt period, the contact must be responsive to their query.
    • Please respond by Feb 5
      [Frederic] Follow-up open team-compass issue to discuss the scope of the project: Participating in Security Bug Bounty program #174

• Mehmet

  • JupyterLab Desktop rewrite
    • Major upgrade with architectural changes and new UI
    • Demo
    • Please share feedback on the PR
    • Installers for testing

• David Q.

  • Jupyter AI
    • Compass issue: Package location for Generative AI in Jupyter #172
    • Name change from Jupyter GAI => Jupyter AI
    • Call for council consensus
  • MathJax 3 upgrade
    • Update to MathJax 3 jupyterlab#7218
    • Drop version number from package name?
      • +1 from @jasongrout to renaming the package in core to just mathjax - this is more of a historical artifact since the packages were originally developed outside of JupyterLab (IIRC)
      • [Frederic] 👍
    • Why the “dual-package” pattern in JL core packages?
      • @jasongrout - the idea was to promote good patterns around code reuse - that the core code and interfaces could be shared and extended in different plugins, and replacement plugins wouldn't have to import stuff specific to an existing plugin. This particularly applies to exporting the tokens used by a plugin.
      • @jasongrout - one technical limitation we were dealing with was lack of tree-shaking. If we had tree-shaking, it helps us have lightweight imports without needing to have separate packages.
      • [Mike] it is important that we do not depend on extra packages so that downstream (like Notebook) can re-use these core packages.

• Jason W.

  • Culling old Jupyter 4.0.0 issues before release
    Booking at least 30 minutes to triage that list next week

• Andrii I.

  • Looking for place in jupyterlab code that handles choice and activation of a next tab when current tab is closed in TabBar (trying to fix jupyterlab/jupyterlab#6648)

• tony

  • accessibility meeting 15 minutes after the hour. agenda

• Jason W
  • Triaging issues in the 4.0.0 milestone
  • Feature deadline is 2023-02-28 for 4.0.0; we need to commit to issues soon or move them en masse to a provisional milestone. If nobody picks up a provisional issue (by commenting on it or by assigning it to yourself), we can move it to Future

• Frederic

  • JupyterLab 3.6.0 (and 3.6.1) released

  • jupyterlab/rtc old experiment and jupyterlab/jupyterlab_rtc new version following Move RTC in a separate extension
    Jeremy points out right fully on Gitter:

    @fcollonval @hbcarlos as a follow-up to Move jupyter-server-ydoc in this organization #175, I was wondering if you had considered reusing the jupyterlab/rtcrepo instead of jupyterlab/jupyterlab_rtc?

    [Frederic] The decision is to merge the two by keeping the old experiment in a specific branch to ease its discoverability.

• Jeremy

Agenda

• Frederic

  • Lumino 2 release
    • Is it ok to make a RC? ETA February 22nd
    • The goal is to do a RC now and the final release end of February when we do JupyterLab features freeze.
      Menu improvement PR - should be ready very soon.
  • Process to grant Triage rights
    • @HaudinFlorence is interested
    • @jasongrout: In the past, we've been pretty liberal with triage rights - if someone is legitimately interested in helping, please let them!
  • RTC package name
    jupyter_collaboration or jupyterlab_collaboration
    [William] "collaboration" can meet a lot of things that have little to do with realtime collab. (E.g., mailing around files is a form of collab, sharing and pr's, etc.)
    [Mike] jupyter sounds good
  • Extract build tools from JupyterLab
    JupyterLab 3.6 depends on Rust compile code. This brought trouble to extension authors to package/build their code on some platform where the Rust compile packages are not available.
    Do we want to extract the builder tool for 4? If yes, who want to lead on this?
    (@kafonek ypy wheels for aarch64 PR Build aarch64 take 2 y-crdt/ypy#119)
  • Performance meeting after this one.
