Fix test_sys.test_stdlib_dir() when Python is built outside the source tree: compare normalized paths.

vstinner · Oct 7, 2021

@ericsnowcurrently: In a perfect world, we would be able ot normalize paths in C, but for now, I think that it's ok to have build/../ in sys._stdlib_dir. There is the same issue with sys.executable.

I propose to fix the test, we can revisit normalization during Python startup later.

You may want to have a chat with @zooba, who has been threatening to make getpath.c pure Python (frozen). 🙂

LGTM

Thanks for doing this.

@vstinner, do we have a buildbot for out-of-tree builds? Clearly I've missed cases where I broke that with some of my recent work.

I rewrote getpath.c in pure Python: #23169

But it changes the behavior, Nick Coghlan requested a PEP. I wasn't very motivated. I abandonned my PR.

It seems like we don't. The issue was catched by my colleague Miro @hroncok when he built the Fedora Python 3.11.0a1 package.
