- Issue: Remove more deprecated importlib APIs from Python 3.12 #98040
|
Still lots of test failures and probably more things to remove, but it's a start! |
|
@brettcannon @ericsnowcurrently Well, this branch is already getting pretty big. Pull a thread, unravel a sweater. There's still some things to do (see the ticket), but it's not too late to provide feedback. I was pretty aggressive in removing things that seemed to be obsolete or testing obsolete APIs, so hopefully I wasn't too eager to remove things. Feedback welcome! |
However! pip 22.2.2 still relies on pkgutil.ImpImporter so these things cannot be removed until this issue is resolved: pypa/pip#11501
|
Should this PR be a draft until the tests are passing? |
Yes, done. The blocker is being worked on upstream so I think pip 23.0 will likely unblock this PR. In the meantime, I'll keep the branch clean as is. |
Plus, it's a private, undocumented API.
* test.test_importlib.fixtures.NullFinder * ...BadLoaderFinder.find_module * ...test_api.InvalidatingNullFinder.find_module * ...test.test_zipimport test of z.find_module
There was a problem hiding this comment.
There's quite a few places in the docs where we need to update cross references as of this PR (mainly pre-fixing with an !) -- though as they're on lines too far from the changes I can't do inline suggestions.
Would you be happy for me to push to this branch with said docs cross-referencing changes?
A
Yes, this would be very helpful, thanks. |
Done, thank you! A |
Thank you! |

The `MyFinder` subclass of [`MetaPathFinder`](https://docs.python.org/3.11/library/importlib.html#importlib.abc.MetaPathFinder) currently only implements the deprecated `find_module` method. That deprecated method was [removed](python/cpython#98059) in Python 3.12. This change adds an implementation for its replacement method called `find_spec`.
The included `six.py` is from version 1.9.0. This version is not compatible with Python 3.12, which [removed](python/cpython#98059) the deprecated `MetaPathFinder.find_module` method. This change updates `six.py` to version [1.16.0](https://github.com/benjaminp/six/blob/65486e4383f9f411da95937451205d3c7b61b9e1/six.py), which uses the replacement `MetaPathFinder.find_spec` method.
