Agenda

• Mike

  • Fix scrolling on undo/redo and selection restoration - RTC fallout: Fix scrolling and selection restoration on undo/redo jupyterlab#17158
    • what was the reason for vendoring y.js bindings?
  • help with PR reviews needed, PRs coming in are not hard!
  • stabilizing cells height draft Stabilize cell height when scrolling jupyterlab#17132
  • completer (and inline completer) gets triggered when collaborator is typing Completer (and inline completer) gets triggered when collaborator is typing jupyterlab#17172
    • we need a special annotation to ignore some changes
  • 4.4.0 beta

    • Allow customizing the ServiceManager with plugins jupyterlab#16794 - marked as ready for review 1 hour ago 🎉
    • Allow changing the position of the code console prompt cell, add settings and toolbar items jupyterlab#13837

• 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 notebook and lab can't open in RTC jupyter-collaboration#390 (comment)

    • 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. Should most collaboration python packages depend on jupyterlab? jupyter-collaboration#425

• Jeremy

  • Allow customizing the ServiceManager: Allow customizing the ServiceManager with plugins jupyterlab#16794
  • Allow changing the code console prompt cell position: Allow changing the position of the code console prompt cell, add settings and toolbar items jupyterlab#13837
