Whoops. Pinning cloudpickle<2.0 got lost, and now doit does not work with PyPy.

Apparently the pin would not help. Any use of cloudpickle does not work with PyPy.

I guess it will take a while for upstream to solve this...

So I have made cloudpickle an optional import on code. It is still installed by default unless on pypy. (on version 0.37 - unreleased as of now).

Note some tests related to DBM are also failing on pypy...

Thanks. Where can I see the failing tests?

@mattip https://github.com/pydoit/doit/runs/7481585043?check_suite_focus=true#step:13:911 Problem might be just with doit test suite. I will check on my next "open source time slot".

I fixed the failing tests. PyPy 3.8 & 3.9 are now part of CI again.

I will keep this issue open until cloudpickle works with PyPy again...

Thanks!

DBM are also failing on pypy...

This module is also unvendored in e.g. pyodide, which makes patching required to get doit to import.

Seems like leaving the cloudpickle dependency optional, and making dbm a lazier import is a fine path: no dependencies are my favorite dependencies for a low-level tool.
