Looks like this pickle file hasn't been removed. It needs to be removed and probably added to tests/.gitignore.
There's more files missed like this.

So I think the file was removed the first time around. But I think Github shows the diffs for binary files that don't end with the extension .0 as a bit different for the other files. I tried adding them back, checked that there were no diffs and then deleted them again using git rm and I do see the files being shown in the delete mode
delete mode 100644 tests/multidict-pure-python.pickle.1
delete mode 100644 tests/multidict-pure-python.pickle.2
delete mode 100644 tests/multidict-pure-python.pickle.3
delete mode 100644 tests/multidict-pure-python.pickle.4
delete mode 100644 tests/multidict-pure-python.pickle.5
But the UI shows the same. Let me know if you have any other ideas on how to address this

@vrdn-23 your console snippet shows a multidict file, not cimultidict.

Try git rm -f tests/*.pickle.*.

I guess, it might be GitHub's poor data representation, after all (although, I haven't checked in detail).
Anyway, per https://github.com/aio-libs/multidict/pull/924/files#r1463633143, we might need to keep the files, after all.

Okay. I'm following the different threads but I'm not sure what the final resolution is. What is the final specification/requirements we want from this change? Could you update #922 with the new changes/ set of requirements that we need?

You're right. I'll try to circle back later.

Does this work without turning the generator into a list?

If not, please use tuple instead.

There's already a pickle_protocol that is injected through pytest_generate_tests. Can't you depend on it instead of maintaining a copy of the same logic?

Please, use a reasonable variable name for the data you're storing there.

Could you move this into tests/.gitignore?
Also, having text files without a trailing LF is a bad tone.

This test might need renaming since it no longer uses a file on disk.
Also, it seems like test_pickle might cover this case already.

OTOH, upon further reflection, I think I might know why the actual files are committed in Git — this is to ensure that newer multidict versions can load pickles of the older ones.
So we might be treating this incorrectly.
We might need to have a CLI interface for making the files in pytest but keep them. A fixture w/o an in-memory strucutre would be useful, though.

What do these changes do?
Refactors the pickling tests so that the pickles are stored in-memory and not on disk and move them into a purest function-scoped fixture.
Are there changes in behavior for the user?
No behavior changes for end user.
