Release 0.910 planning

[JukkaL]

I'm planning to release mypy 0.910 next week. It's only going to me a small feature release -- cherry-picks on top of 0.902. The main thing I want in is mypy --install-types --non-interactive (#10616). I'll probably also cherry-pick some typeshed fixes (#10621). If anybody wants something else in the release, please leave a comment here.

I probably won't include any new features unless they address some issue introduced in 0.900.

Maybe also cherry-pick python/typeshed#5579

Thoughts on #10560 ? Fixes crashes that have been reported multiple times.

[JukkaL]

Any fixes to crashes are potentially good, as long as the fix doesn't seem risky (since we aren't going to follow our full, safe release process).

[srittau]

The stubgen PRs (#10623, #10624, #10625, and #10626 if it gets approved) would be low risk for mypy itself, but could prevent unsuitable typeshed submissions.

[JukkaL]

The stubgen updates sound all good.

Some other PRs that seem safe:

• Address #10648 #10655 (doc update)
• pyopenssl types package corrected #10656 (type package name fix)
• Don't suggest to install stubs with py.typed files #10652 (don't suggest installing stubs for packages with py.typed)

Since there have been some recent fixes related to type packages, I might postpone the release for a few days until early next week to give more time for further issues to come up.

[JukkaL]

I'd also like to fix #10653 (crash), which is a regression from 0.812, assuming we can find a self-contained repro.

The crash #10647 also sounds possibly bad, though I haven't looked into it in any detail yet.

Fixing #10645 at least partially would also be nice.

Finally, this improvement to --install-types --non-interactive could be nice to have: #10600 (comment)

[JukkaL]

Also it would be good to improve the error message when --install-types can't find a mypy cache (see discussion in #10600).

[TH3CHARLie]

I can help bisect #10653 and see if I can fix it

[hauntsaninja]

mypy_primer can make bisection easier, try: mypy_primer -p test.py --bisect --old v0.812 (although there might be some issues crossing back and forth between getting rid of submodules / if there are other changes you might want to use --bisect-output AssertionError / pass --debug to see what it's doing)

[TH3CHARLie]

cool, I wasn't aware mypy_primer has these functionalities

[srittau]

Another package name fix: #10681.

[JukkaL]

#10653 is the biggest remaining potential release blocker for which we don't have a PR yet. I'll also want to make some documentation and/error message updates, but these are straightforward.

I may skip the typeshed cherry-picks, since I've been busy with other fixes, and we don't have an existing workflow for performing cherry-picks.

[TH3CHARLie]

@JukkaL do you have a hard expected deadline for this release? if so we may need some quick (and therefore maybe dirty) patch to address #10653

[JukkaL]

I don't have a hard deadline, so it's basically "as soon as feasible". I'll have a look at #10653 today.

[JukkaL]

The release-0.910 branch now contains all the things I want. I'll do some more testing and if everything goes well, I'm planning to make the release later today (Tue).

[christianbundy]

There have been ~180 commits since this release, is there anything I can do to help get another release cut?

(Apologies for the necro-bump, I was going to make a new issue but the issue template says not to make issues for questions.)
