Future proofing: treat most warnings as errors in pytest, and fix existing ones #3380

neutrinoceros · 2021-06-26T09:13:22Z

PR Summary

fix #3379
Though independent, this is complementary with #3376.

An important note is that there are some internal deprecation warnings with no obvious solution yet, so I'm adding them to the ignore-list in conftest.py but they will need to be addressed in future releases. Specifically, I'm talking about fields ("all", "px") and ("gas", "px") (respectively "py", "dpx" and "dpy"), that are used internally in slice selectors, but never with explicit field/particle types. Getting to a stable solution here requires much more thought and design that what I'm solving here so I'll defer it to future works, and in any case it's not as urgent as other deprecation warnings because it's internal so it won't break haphazardly.

TODO

pass CI
document why each ignored warning gets a pass (comments)

There remains only one failure in the py38_unittest job but I'm struggling to reproduce it locally. Any help would be greatly appreciated.
edit: done ! ✅
Hopefully this is the last thing that needs solving here, though I'm writing this before I can see the results from the py38 job on Jenkins.

To anyone wondering: the reasoning here is that the distutils builtin package is slanted for removal in Python 3.12 (which should be released around October 2023), but it is currently used in several places in yt, making it de facto incompatible with Python 3.12
Solving this doesn't seem like a priority but I'll document it as an issue !

I'd like to see one of the changes reworked, but otherwise this looks good to me.

I think some like this may arise from field detection.

oh, good call ! I'll keep this in mind if I ever feel daring enough to fix these :)
