Vendor setuptools 67.7.2 #11997

pfmoore · 2023-04-25T15:20:33Z

This PR vendors setuptools 67.7.2, and suppresses the deprecation warning for pkg_resources.

pfmoore · 2023-04-25T15:25:03Z

I've only tested this manually, using python -Werror -m pip list, which produces an error without the warning suppression code, but works with it. We don't test that pip works with -Werror, and I don't honestly think this is the time to start doing so - if we want to do that (I don't personally think we need to), let's cover it in a follow-up PR for 23.2.

hroncok · 2023-04-25T15:33:33Z

How does this suppression work when pip builds a project that imports from pkg_resources (e.g. in the setup.py script)? I suppose this goes trough subprocess, so the warning will still be visible in that case, correct?

I suppose this goes trough subprocess, so the warning will still be visible in that case, correct?

If the build succeeds, then no. If it fails, whatever the default behaviour with warnings is.

hroncok · 2023-04-25T15:36:37Z

I was just checking whether the behavior stays the same as now. I suppose your comment answers that.

pradyunsg

Hmm... the major version bump is due to a behaviour change in handling of parsed_version relying on PEP 440, which is #11715 basically.

I think it's worth doing a manual test that having a non-PEP 440 version installed in the environment doesn't blow up pip unconditionally. If it does, we should protect against that.

The rest LGTM!

pradyunsg · 2023-04-25T15:43:00Z

I'll be walking to PyCon US's sprints now; and will dig into this if I don't get pulled into a conversation. :)

I think it's worth doing a manual test that having a non-PEP 440 version installed in the environment doesn't blow up pip unconditionally. If it does, we should protect against that.

I'm not sure I follow what your concern is, so I'd appreciate it if you could manually test this.

If it does blow up, then we can consider how best to proceed, but I'm inclined to say that in that case we would need to stop and consider the implications carefully, and not let ourselves be pushed into rushing a solution just because of the time pressure around the imp deprecation work for Python 3.12. Ultimately, the problem here is that setuptools hasn't left their users (i.e., us!) with a clean upgrade path, and that's something we should be pushing back on them, rather than firefighting multiple breakages as part of our release process.

Looks like that's not an issue! :)

Also, this needed me to do a hacky-ish install (to achieve a 23.whatever version being installed). With the latest setuptools, you have:

So we don't have a problem, correct? As another data point, we didn't have any reports of issues with non-PEP440 versions in the period when 23.1 was released before 23.1.1, so that indicates we don't have a problem, as well.

If you're OK with this, then just approve and I'll merge it and cut a 23.1.2. And then hopefully we're done...

We do not, and this is good to go!

Thanks, I'll do 23.3.2 tomorrow (UK time).

+    # Suppress the pkg_resources deprecation warning
+    # Note - we use a module of .*pkg_resources to cover
+    # the normal case (pip._vendor.pkg_resources) and the
+    # devendored case (a bare pkg_resources)
+    warnings.filterwarnings(
+        action="ignore", category=DeprecationWarning, module=".*pkg_resources"
+    )


Would this also filter out pip._internal.metadata.pkg_resources? It’s probably fine since we probably won’t deprecate anything in that module anyway (any new development happens in the importlib.metadata backend instead), but I just want to clarify this in case.

Yes, it would. Ideally, I'd have made the filter just on pip._vendor.pkg_resources, but that wouldn't have handled the devendoring case. I could have had 2 separate filters, or even left it for whoever does the devendoring to sort out, but that seems unnecessarily unfriendly.

I'd be fine with someone submitting a PR to tighten this up (I didn't even think of pip._internal.metadata.pkg_resources), but like you I think it's probably fine as it is.
