This is a meta issue tracking all the things that need to be cleaned up in the import system. From removing long deprecated APIs to migrating internal access to __spec__, we'll have several task lists for each related set of clean ups.

@brettcannon @ericsnowcurrently for visibility.

Removing deprecated APIs

Over in What's New for Python 3.11 there's a long list of things that have been deprecated long enough that they can be removed in Python 3.12. Here's that task list for tracking purposes. Watch for linked PRs (maybe one big one or many small ones -- we'll see!).

@brettcannon @ericsnowcurrently for visibility.

Update docs

  • Make sure examples and details from PEP 302 are covered in the importlib docs (/cc @Yhg1s )
  • Remove https://docs.python.org/3/reference/import.html#open-issues (PR)
  • It would be really nice to have a diagram.
  • (import_machinery.rst) how about a section devoted just to the attributes of modules and packages, perhaps expanding upon or supplanting the related entries in the data model reference page?
  • runpy, pkgutil, et al in the library manual should all get “See Also” links at the top pointing to the new import system section.
  • Add more explanation regarding the different ways in which __main__ is initialized?
  • Add more info on __main__ quirks/pitfalls (i.e. copy from PEP 395).

Missing deprecations

Here's a list of related APIs that have not yet been deprecated, but should be. We'll deprecate them in 3.12 and remove them in 3.14.

  • pkgutil.find_loader()
  • pkgutil.get_loader() (or it needs to be reimplemented to not use find_loader())

I've removed importlib.utils.set_loader, importlib.utils.set_package, and
importlib.utils.module_for_loader from importlib.utils in #97898 🎉

From the meta checklist:

Deprecate pkgutil.find_loader()

I kind of think we're okay here, at least for 3.12. This uses importlib.util.find_spec() so I feel like it's not so urgent to deprecate and actually probably has some utility.

Deprecate pkgutil.get_loader()

Similarly, I'm not sure this even needs to be deprecated. It is implemented in terms of the above, and thus find_spec(), and it has some potentially useful wrapper semantics.

I'm going to mark both issues as complete and not deprecate it in 3.12.

@brettcannon @ericsnowcurrently - I think this PR is ready for review. I feel good that we've implemented all the removals we need for 3.12. Like the other issues, we can address the doc updates after beta 1.

[For the imp module, I created issues for most of the 71 projects in the PyPI top 5k (listed at python/cpython#98573 (comment)), where I could find their tracker. And some already had issues.

I've checked off projects which had already fixed but not yet released, or have fixed since I created the issue, or where the project is unmaintained or otherwise abandoned and a fix is unlikely in any case.

Currently 24/71 (34%) are checked off. In the issue I pointed to the 3.11 imp docs which have suggestions of how to upgrade each functions/constants, and most seemed fine with that so far, except for one noting imp.load_source has no suggestions.

Due to nose being unmaintained (number 41 in your list), that's why there's pynose now (number 55 in your list).
It's a complete drop-in replacement for all occurrences. (Let me know if that isn't the case.)
