Wednesday 21 October

Participants

• Bernard
• Sumana
• Pradyun
• Ernest
• Georgia

Agenda:

• #8713: Pip downloads lots of different versions of the same package
  • From yesterday's meeting "we need documentation"

    • Proposed: https://editor.nuboso.ei8fdb.org/s/SJZgHFTPw

  • Also like to propose:
    • helping the user remove the packages pip backtracks through.
      • Better solution to this is improving pip cache

  • Paul gave comments - https://python.zulipchat.com/#narrow/stream/218659-pip-development/topic/blockers.2Fbug.20triage/near/214045901

  • Ernest: pip should probably present the message before downloading 8 packages.
    • GA: This is a good point and good feedback!
    • Ernest: We should present the message immediately when backtracking the choice, the first time (i.e. at first backtrack).
      • Bernard: we'd discussed this at some length during the initial discussion and kind-of pulled this number out of the air.
      • B: Don't think presenting a message that pip "might" do something.
      • Sumana: show "this could take a while" message after the 2nd backtrack
        • Pradyun: We have n = 8, we can change it to 1 -- I think it's reasonable and a good change for all the reasons Ernest has mentioned.
        • TODO: Pradyun to add an n=1 threshhold to display the initial info message
  • Next steps:

    • Pradyun and Bernard to discuss what possible solutions users can try to - https://editor.nuboso.ei8fdb.org/b7-Q2qrdTom5KTMZGXEoNA?view#Possible-solutions

    • Bernard to make PR.
      • Markdown-to-rST
        • Sumana suggests using pandoc

        • Pradyun: if you'd like, feel free to look at https://pradyunsg.me/furo/reference/ for A/B differences between them?

      • can possibly get this done this evening
      • ideally: merged in tomorrow
• Note: Next week is Daylight Savings for parts of the world! Just to flag the meeting time might change for some folks, and not for others!
  • Ah fun.
• Will we release pip 20.3, with new resolver as default, within next week?

  • https://github.com/pypa/pip/projects/5

    • https://github.com/pypa/pip/issues/8664 performance

      • TODO: Sumana: We've not mentioned that people should try pip 20.2.4 in the issue -- DONE

    • Requirements with (potentially conflicting) options https://github.com/pypa/pip/issues/7846

      • legacy pip has inconsistent behavior.
      • TODO: defer to post-release -- DONE

    • https://github.com/pypa/pip/issues/8495 & https://github.com/pypa/pip/issues/8492 New resolver error message is confusing if a package has inconsistent dependencies

      • currently being iterated.
      • TODO: Pradyun to make a comment
      • Georgia: we have survey feedback and are thinking through the best way to deliver what we can
        • Nicole is planning to post the synthesis from the survey on the issue.
        • so, when will this be a merged PR? We're not sure.
        • Sumana: urgency
        • TODO: Georgia: will check with Nicole, follow up, unblock. Thinks it is pretty close
          • team has been looking at and synthesizing survey results
    • pip editable install with new dependency resolver fails despite correct version numbers #8785
      • "next step here is for @uranusjr and @pradyunsg to have a chat about what to do next."
      • They talked, but Pradyun needs to talk with him again to come up with a solution.
      • TODO: Pradyun to move conversation to issuetracker so it is visible

  • https://github.com/pypa/pip/projects/6

    • covered in other discussions

  • https://github.com/pypa/pip/milestone/38

    • Question about https://github.com/pypa/pip/issues/8333 Check in prepare_linked_requirement for an existing directory is setuptools-specific #8333

      • Does Pradyun need to do anything about this?
      • DONE: Sumana tried to delegate to others -- Paul will try to take a look
  • So: yes. Let's try to release Wed or Thurs, the 28th or 29th.
    • Pradyun: feels good.
      • date sounds fair. Maaaaaaybe a beta on 28th or 29th if we can't manage a stable release on 28th/29th. if we have 1-2 outstanding PRs/issues.
        • Sumana: and then a stable release the subsequent release, in early Nov.
    • Georgia: feels good
    • Bernard: feels good
    • Sumana: neutral
  • TODO: Sumana: start drafting announcement blog post(s)/email(s)/tweet(s)
• Early November - US may have civil unrest, let's reduce what we ask of our US people that week
  • Simply Secure is aiming to not have any meetings on Nov 3rd + 4th to allow everyone flexibility

  • TODO: Sumana to braindump some "things to do immediately after release" thoughts into Zulip or GitHub for Pradyun to use in case he needs to step up in her stead

  • TODO: Sumana to ask Bethanie to reschedule Nov 3-4 meetings, but NOT to Nov 5-6 (Bernard)... perhaps do Monday instead?
