In Lib/test/test_inspect/inspect_fodder.py, the last class has a bunch of comments where the comment includes the specific line number, i.e. # line 95 is line 95 of the original file. The updates in this PR include adding lines to that file and so those comments are no longer on the lines that they reference.

I'm having trouble getting the test suite working locally to get a sense of if that matters at all, but I'm guessing that some inspect tests may be looking at those comments for some reason or another?

I believe I fully reverted that in my later commits. There should no longer be any changes to inspect_fodder.py. Which commit have you pulled?

Those comments are there to test the comment extractor part of inspect.py. After a bit of testing I felt adding new stuff to the fodder file required changing more hard coded numbers than I thought was worthwhile, so I made a new fodder file.

I'm also having trouble getting the test suite working after my last pull from main. Are you getting the same "cannot import name 'Union' from '_typing' (unknown location)" error?

ope, my bad, was looking at a commit and spent so long trying to get the devcontainer to work you had made new updates since then that I didn't look at.

can you please check the failing tests here please, Tests / Hypothesis tests on Ubuntu (pull_request) ? if they are relevant failures?

Syncing with main this afternoon seems to have fixed it. I'm not sure why it was failing in the first place, since it seems to test code that I didn't modify at all. The tests ran fine on my Ubuntu terminal before and after I submitted so that was a bit baffling to me.

The test is flaky I think (we've seen similar failures elsewhere)

@picnixz Do you have any thoughts on this pr? It's been a couple weeks and I'm hoping for core dev to look at it.

I don't have time until the end of the week so I'm requesting myself a review

I haven't looked at this PR yet, but note that there is a duplicate of this function in the pydoc module.

Good to know then. @lincolnj1 can you check also the pydoc module please?

It seems to me that you went overboard with the tests (the simplest test would have been enough),

This is a trauma I had from maintaining Sphinx. There were so many edge cases because of inheritance. It also serves as a robust way to detect future possible regressions (but I agree that it's a bit of an overkill).

Yes, it seems that one is also broken in the same way (see below). I'll take a look at fixing it. Should I open a new PR to fix that or keep working in this one?

Edit: I used the private _getdoc method here when I should've used the public getdoc, but the behavior is consistent using either method.

If there are plans to backport this change, you need to fix the pydoc version too (it is just a copy). Otherwise, you may wait until #132686 has been resolved.
