Setuptools 60 is breaking tests

[uranusjr]

Filed for tracking and discussion. Unfortuantely I don’t (and won’t for a while) have time to look into the cause, but from a quick peek, it seems like this is a debundling issue caused by setuptools’s distutils vendoring adoption:

self = <setuptools.command.egg_info.egg_info object at 0x000001ABC5892140>
dist = <setuptools.dist.Distribution object at 0x000001ABC58A0790>

    def __init__(self, dist):
        """Create and initialize a new Command object.  Most importantly,
        invokes the 'initialize_options()' method, which is the real
        initializer and depends on the actual command being
        instantiated.
        """
        # late import because of mutual dependence between these classes
        from distutils.dist import Distribution
    
        if not isinstance(dist, Distribution):
>           raise TypeError("dist must be a Distribution instance")
E           TypeError: dist must be a Distribution instance

Distribution = <class 'distutils.dist.Distribution'>
dist       = <setuptools.dist.Distribution object at 0x000001ABC58A0790>
self       = <setuptools.command.egg_info.egg_info object at 0x000001ABC5892140>

Setuptools is using isinstance to check whether dist is of the correct type, but it imports Distribution from its vendored distutils, which dist is actually created from the system distutils. Or the other way around, I’m not sure. But something like that, I think. It’d be awesome if someone could dig deeper into this and file an issue in pypa/setuptools with deeper investigation.

Regarding pip’s situation, I think this does not affect the actual code base (which never imports setuptools), only the test suite, and we should be able to work around this by capping setuptools to <60. Or with some workaround in test setup.

/cc @jaraco for awareness.

As a reminder, Setuptools isn't vendoring distutils. It's adopting it. The difference is subtle but important. The adoption means that Setuptools intends to absorb the functionality and supersede stdlib distutils without there being any standalone distutils.

Part of the issue here is that Setuptools does expect that distutils comes from exactly one place (stdlib or local), but specifically for the pip case, the hook that directs imports to the Setuptools-hosted version of distutils is disabled.

I'm pretty sure if pip can eliminate its reliance on distutils per #8761, that exclusion could be removed, and this issue would resolve itself.

Somehow related: Since setuptools v60 at least on Debian running get-pip.py over an existing pip + setuptools fails, when the Debian python3-distutils package is installed, e.g. as dependency of the Python development headers package:

/usr/local/lib/python3.9/dist-packages/_distutils_hack/__init__.py:24: UserWarning: Distutils was imported before Setuptools, but importing Setuptools also replaces the `distutils` module in `sys.modules`. This may lead to undesirable behaviors or errors. To avoid these issues, avoid using distutils directly, ensure that setuptools is installed in the traditional way (e.g. not an editable install), and/or make sure that setuptools is always imported before distutils.
  warnings.warn(

This _distutils_hack comes from get-pip.py. Looks like removing any use and detangling distutils from pip in favour of setuptools would solve both issues.

[pradyunsg]

This _distutils_hack comes from get-pip.py.

It does not. This comes from setuptools directly (https://github.com/pypa/setuptools/tree/main/_distutils_hack), and this style of failure should likely be reported as a bug against setuptools or Debian (it might have already been reported, so please check for duplicates before filing a new one).

@pradyunsg
Ah you're right, I missed the /usr/local/lib/python3.9/dist-packages/setuptools/__init__.py showing that it's coming from setuptools.

@jaraco
Many thanks for sending it upstream already.

I forgot the workaround in case someone else runs into the same issue:

pip3 uninstall -y setuptools
python3 ./get-pip.py

Of course if pip is installed already, one usually wouldn't use get-pip.py again, but we kept calling it as a generic install/upgrade/repair step on scripted reinstall.

[MichaIng]

Hmm, while setuptools v60.3 solved the reinstall failure, it became even worse as while get-pip.py run through without error pip remains uninstalled:

In #10796, I've worked around this by using the standard library distutils. I don't like this at all, but I can't really think of anything lower-effort to unblock making 22.0.

I think we should keep this issue open, until we drop the "hack" added in that PR. I might end up spending some time to modernise our test scaffolding and venv handling, once #10421 winds down. :)

[pradyunsg]

Okay, this is no longer a release blocker. :)

Just started updating pip to latest version and found that some new units are failing.
I'm currently setuptools 60.9.3.

[ichard26]

Does this issue still need to be around given we're approaching setuptools 70 and at the moment pip is green?

[pfmoore]

The hack added in #10796 seems to have been removed since (in #11293). As @pradyunsg only wanted this issue kept open until that happened, I agree this can now be closed - @pradyunsg do you object?

[ichard26]

I'll close this for now. We can revisit this if needed.
