Description As a consequence of the above, when I run pip3 freeze, I get a whole load of seemingly nonsensical warnings:

@cjerdonek’s change at https://github.com/pypa/pip/pull/6538 improves this slightly (previously there was no clue that these weird names referred to anything in the site-packages directory), but as a naive user this I’m still left unsure what I’m being told or what to do about it. When encountering this message, I’m left adrift in a couple of ways:

  1. The new message falls short of explicitly stating that the warning was triggered by a folder with a weird name in the site-packages directory. It mentions the directory, and mentions the weird name, and then leaves me to guess.
  2. The name given isn’t even a perfect match for anything in the site-packages directory! The subdirectories triggering the errors start with a ~, but in the error message that ~ has somehow shapeshifted into a -.
  3. Even if I correctly infer that the weird subfolders in my site-packages directory somehow relate to this error message despite the above hurdles, I’m still left confused and guessing about what that implies. Why are they there at all? Should I delete them or is that going to break my Python installation somehow? Is something horribly corrupted and do I need to reinstall Python? The error message gives me no guidance; it suggests that something is wrong with the fact that these folders exist, but that’s all the help I get.

(The answer to my rhetorical questions in point 3 is that they’re temporary folders created by Pip, possibly left behind when I killed a Pip process previously before it could clean up, and that deleting them is safe. But I’m not sure how I could’ve found this out without stumbling across this Stack Overflow answer.)

It’s got to be possible to avoid confusing and worrying the user in this way.

A possible easy fix

Make pip freeze ignore ~-prefixed folders without logging a warning. From what I understand from https://stackoverflow.com/a/57488427/1709587, ~-prefixed directories are guaranteed to be temporary directories. So just treat them like they don’t exist in freeze.

A possible harder fix

Attack the root cause by ensuring that these temporary directories eventually get cleaned up properly, even if a pip process gets uncleanly killed. I see two strategies for this:

  • Check for their presence and attempt cleanup on every pip invocation, even if the command is to do something unrelated (similarly to how git, by default, sometimes decides to run garbage collection on the objects in your local repo).
  • Use the OS’s temp directory (e.g. via Python’s builtin tempfile module) instead

(I’m throwing both these ideas out naively, without much understanding of Pip’s internals; I apologise if either of them is stupid for a reason I’m not seeing.)

There is a middleground here: leave undocumented folders that can’t be automatically cleaned up, but avoid treating them like installed distributions. The root issue is actually in pkg_resources, where dist-info directory names are consumed without validation. But pip can probably do some lateral cleanup to avoid them from being shown to the user. Would this be good enough?

The AdjacentTempDirectory was originally introduced in #6029

Hmm - sounds like we should ping @zooba, then, since he wrote #6029 and may have some wisdom to offer.
