Participants:

• Sumana
• Pradyun
• Bernard
• Georgia (30 min in)

Agenda:

• https://github.com/pypa/pip/pull/9017 -- Log an informational message when backtracking takes multiple rounds on a specific package #9017

  • P just merged it. \o/

• https://github.com/pypa/pip/pull/9040 -- Include backtracking in user guide

  • Feedback?
  • [Pradyun and Sumana review it live during call]

• https://github.com/pypa/pip/issues/7744 -- Handle conflicts from installed packages when updating other packages

  • Prioritization: OK to defer to _after_ 20.3.beta1 or should we do it *now*?
    • SH: I think can defer to after the beta.
      • Tradeoffs:
        • Want beta out by this week. But don't want to put more work on P's desk with all that currently needs to be done.
      • People who may not have tried 20.2.4, might try this. There's a benefit to better error messages reducing confusion + support load.
    • P: would prefer to wait til after the beta

    • GA & BT are fine with deferring to Pradyun!

  • https://github.com/pypa/pip/issues/8495 -- Error message update: inconsistent/conflicting dependencies

    • #8495 -- before beta or ok if it is after? implementation: Show dependency tree in ResolutionImpossible error message #9036

    • Language changes in error message, logic changes in behavior
    • what's achievable by this week? nice to have for beta, definitely have it for 20.3 release
    • We can also release another beta 2 days later with this!
    • Resolved: not hold the 20.3 BETA for this fix
• Resolver survey
  • BT: the link will work for all future survey exports
  • Pradyun is looking at the reports

Pradyun planning the rest of his evening:

• https://github.com/pypa/pip/pull/9056 -- Documentation update: migration guide (review)

• https://github.com/pypa/pip/pull/9044 -- Documentation update: resolver default (review)

• https://github.com/pypa/pip/pull/9019 -- Flip the switch on new resolver (implement)
