Agenda

• Andrii

  • Looking for review / advise for "When an entire cell is extracted from lsp virtual document do not add an empty code cell equivalent, do not add new separator lines after it" https://github.com/jupyterlab/jupyterlab/pull/17412

    • Currently only prevents addition of separator lines
    • When we say "do not add an empty code cell equivalent" to virtual doc, does it mean that cell should not be represented at all / total count of cells should be decreased by 1?
    • With jupyterlab-lsp and 'python-lsp-server[all]' installed, suggestions / warnings do not work in dev-mode so testing changes in /jupyterlab/packages/lsp/src/virtual/document.ts that affect suggestions is non-trivial. Any suggestions on optimal dev workflow?

  • 2 recently discovered Notebook issues breaking user experience / not allowing users to work:

    • https://github.com/jupyter/notebook/issues/7597
    • https://github.com/jupyter/notebook/issues/7600

  • I wanted to organize a bug bash(es) for JLab 4.4 so I was curious

    • What is the release plan and if now / soon would be a good time to do the bug bash(es) or if there are still major changes and features expected to be pushed
      • RC was planned for today, there are 2 blocking issues with open PRs https://github.com/jupyterlab/jupyterlab/issues?q=is%3Aissue state%3Aopen label%3A"tag%3ARelease Blocker"
      • Release plan is (always) pinned in the JupyterLab repo https://github.com/jupyterlab/jupyterlab/issues/16904
    • Should it be a public bug bash during JLab call? Even if we don't do a public one I plan to do an internal one with my team
      • No opposition to having a bug bash next week or next week +1

• Vidar

• Andrii

  • [jupyter-collaboration] Issue #390 "notebook and lab can't open in RTC" - I can reliably and easily reproduce this problem by updating from jupyterlab-chat version that uses jupyter-collaboration v2 to one that uses jupyter-collaboration v3; .jupyter_ystore.db file is not getting moved / updated https://github.com/jupyterlab/jupyter-collaboration/issues/390#issuecomment-2591686307

    • David Q: We should explore dropping YStore by default.
    • Open new issue for a) adding a configurable for enabling YStore & defaulting to False, and b) making YStore better. Instead of a document_ttl, we should probably just have max_updates. This bounds the disk use and makes disk use independent of when the updates were made.

  • [jupyter-collaboration] Issue #425 "Should most collaboration python packages depend on jupyterlab?" Are there any downsides to adding a JupyterLab dependency pin to jupyter-collaboration? A mechanism like this to specify which versions of JupyterLab current version of jupyter-collaboration is compatible with would help with versions mismatch issues. https://github.com/jupyterlab/jupyter-collaboration/issues/425

Wednesday, July 24

Agenda

• Frederic (won't attend)

  • New security rules and update snapshots job
    I looked at how best handle the current situation that prevents the update job to be executed on non-member PRs. It looks like the easiest would be to create a team with Read access (aka nothing more than what you can do on public repo) in which we invite trusted contributor as outside collaborator.
    For example I invited a GSoC contributor for test purpose (should be dropped at the end of this meeting if the approach is deemed wrong):
    
    Then on one of her PRs, the first update snapshot comment failed (she was not yet a collaborator). The second passed (she accepted the invitation).
  • Follow up in a JupyterLab issue?

• Jason W

  • Request for comments: remove the move up/down buttons from the cell toolbar?

  • JupyterLab 4.3 beta/feature freeze approaching
  • Pull requests with "Needs Review" status: Needs Review
    • https://github.com/jupyterlab/jupyterlab/pull/10596
  • Issues with important labels: Needs Design and Needs Discussion

Wednesday, July 17

Agenda

• Andrii: PR 14375 "Settings Editor: remove pluginslist grey background" is merged. We wanted to release this settings editor UI change early as a part of an alpha to allow for user testing and feedback. Is there a plan for 4.3.0a3 before 4.3.0b1?

  • Mike: yes, we are in alpha we will switch to beta on August 5th as per https://github.com/jupyterlab/jupyterlab/issues/16315
  • Would be nice to wait for more PRs to be merged before doing another release, let's touch basis on new alpha release next week

    • Question: Integration in Lab?
      • I'd like to add menu entries in the language menu to Install a language and Help with translation. The former is not related to the extension but the latter would install the extension (another possibility is to redirect to the Lite instance or the extension repo).
      • Should that extension be in the jupyterlab GitHub org? - for now it is in lab contrib
  • Request for 4.2.x release following ws bump backport
    • What is the status of 4.2.x?
      [Mike] We can cut a new patch release - no-blocker

      • I'm not able to update the snapshots through comments - is it expected with the latest security changes? Should we relax the condition on the status of the commenter?
    • Builder is making good progress, we got jupyter labextension build/develop/watch
      • Next steps is gonna be to include jlpm and @jupyterlab/builder within that repo.
      • I have a question of code organization. That idea started as a PR in the hatch jupyter plugin. And seeing the link that that hatch builder will be tightly link to the new builder, should we use a single repo for both? I recall some counter arguments from Nick but can not find them any more
  • Make the services manager PR a plugin

• Andrii: JupyterLab PR 14375 "Settings Editor: remove pluginslist grey background" is ready for review, has green CI, and was approved by Jason W. Looking for more reviews or consensus that it's good to be merged.

      • Project Jupyter's multiple software tools/programs
      • concepts around interactive computing/kernels/notebook format
      • Lab's modularity and extensibility, replacing or modifying pieces, building new apps with Lab components

• Eric G

  • I want users to be able to spawn Hex Editor document widgets to view files in the Lab file browser
    • Currently I'm subclassing ABCWidgetFactory and using docregistry.addWidgetFactory in an attempt to accomplish this
    • ABCWidgetFactory needs an IModel subclass, so I don't know how to use the existing model factories with that class…
    • Suggestions:
      • The ImageViewer code may have relevant solutions
      • Potentially Mime render extension may be a solution, some devs shared concerns that a new widget may override defaults, but it seems that only happens when specifically requested
  • Explanatory docs are in progress, rewrite of main extension page in progress

    • Any other features that I missed? Let's do triage at the end.
      • (the screen reader aria live thing will require more work so I will bump it to 4.3)
    • Let's announce this today:
      • anyone willing to review user-facing changelog?
  • Fix for non-US keyboards ready for review (again) https://github.com/jupyterlab/jupyterlab/pull/15927
    • Side note: some other web IDEs just allow users to choose keyboard layout
  • jupyter-ai completer:
    • Distinguish between completion and chat models
    • Move methods generating completion replies to the provider
    • Consider changing the default shortcut for accepting inline completions

• Zach:

  • Make the default drive in Contents API configurable
    • Issue: https://github.com/jupyterlab/jupyterlab/issues/16099
    • Draft PR: https://github.com/jupyterlab/jupyterlab/pull/16141
    • Jupyter Collaboration breaks everything because of this issue
      • https://github.com/jupyterlab/jupyter-collaboration/issues/202
    • Should I pursue this any further or focus energy on the service manager and solve this along the way (see next point)?
      • Focus on pluggable servicemanager.
  • Pluggable ServiceManager
    • https://github.com/jupyterlab/jupyterlab/issues/15329
    • Previous work explored making a special case plugin for service managers: https://github.com/jupyterlab/jupyterlab/pull/13558
    • Do we add an additional initialization phase just for the service manager?
      • Today, servicemanager gets loaded out in the index.js phase, so there is no way to configure it.
    • I'll spend time thinking about this more.

• Eric

  • Service account for ReadTheDocs to grab docs stats (example here)
