lithomas1 · 2023-06-20T18:29:47Z

xref ENH: Python 3.12 support #53665 (Replace xxxx with the GitHub issue number)
Tests added and passed if fixing a bug or adding a new feature
All code checks passed.
Added type annotations to new arguments/methods/functions.
Added an entry in the latest doc/source/whatsnew/vX.X.X.rst file if fixing a bug or adding a new feature.

For those interested, we have
208 failed, 172066 passed, 18996 skipped, 982 xfailed, 84 xpassed, 56 warnings in 2448.38s (0:40:48) =

Not bad, given most are parametrized, but definitely much more than last year 😭 .

I pushed up a fix to use timezone.utc. I think datetime.UTC is > PY311

lithomas1 · 2023-07-11T21:52:37Z

Thanks for updating this, and sorry for losing track of this PR.

I have the Docker image for Python 3.12 set up on my laptop, so I'll try to get some debugging in tomorrow for the Index failures, unless you beat me to it again :).

lithomas1 · 2023-07-11T23:52:14Z

Looks like the major change is

slice objects are now hashable, allowing them to be used as dict keys and set items. (Contributed by Will Bradshaw, Furkan Onder, and Raymond Hettinger in gh-101264.)

Down to 4 tests

FAILED pandas/tests/computation/test_eval.py::TestEval::test_true_false_logic - DeprecationWarning: Bitwise inversion '~' on bool is deprecated. This returns the bitwise inversion of the underlying int object and is usually not what you expect from negating a bool. Use the 'not' operator for boolean negation or ~int(x) if you really want the bitwise inversion of the underlying int.

I think I regressed one of the indexing tests in my fixes.

This should be ready now.

why does changing the order matter? the current order is pretty fine-tuned for perf

We need to check for slices in iterators by iterating through them, since they aren't allowed as hash keys.
(It doesn't make sense to have slices as keys in an Index and it breaks way too many things).
This exhausts the generator.

IIUC, this should only lower perf for generators?
(at least the is_iterator docstring only mentions that it will only return True for generators not list and co.)

Matt enabled this again a while back, I think.

very late review comment: would it make sense to make is_hashable_non_slice or something? it wouldn't surprise me if many places that use is_hashable current assume non-slice but didn't get updated by this PR

Yeah sure, I just updated the places that broke in the tests.

Is there a case where we would actually want is_hashable for a slice to equal True, though?
(I was thinking it might be cleaner to make is_hashable always return False for slices. This would be a breaking API change, though).

i think having is_hashable be anything other than a try/except around hash would cause problems. im suggesting a new function to de-duplicate the hashable-but-not-slice checks this introduces

Made an issue #55152.

I don't have the same time that I had in summer to work on pandas, but I'll try to have a look (no promises, though).
