Change LGTM here, but two concerns:

I believe you are supposed to call startloading
, but this assumption that __init__
finished running has never been enforced or made true anywhere else at any time, so it seems fairly sketchy to assume it is enforced here.

Ok. if that's a bigger question, then I'll just directly handle package_locks
in #54674

Yeah, I don't think we've enforced it, but I do think that it's reasonable to start enforcing it. It would be weird if two threads start doing using Foo
, which spins up some C state in its __init__
, but for one of them using
returns before that happens.

The wrong uuid was being used for the fast path for exts (cherry picked from commit 1b6ec0d)

The fast path wasn't respecting package_locks meaning it could return before another thread finished running the packageSee Fix uuidkey of exts in fast path of__init__
