[issue14660] Implement PEP 420: Implicit Namespace Packages
|
|
New submission from Eric V. Smith <eric [at] trueblade>:
I have created a branch features/pep-420 where I'll be developing a proof of concept implementation of PEP 420.
I've checked in a basic version, but it has these issues:
- We need to decide how finders communicate that they've found part of
a namespace package. Per Brett's suggestion, I'm currently returning a
string that means "the returned path is part of a namespace package".
I think that's an okay design.
- I guess we need to create a "namespace loader", so we can initialize __loader__. It's a little odd because it would be a loader for which there's no need for a find_module method. I'm currently setting __loader__ to the finder, which is completely wrong, but keeps things working.
- test_import and test_importlib both fail because they're checking
that imports with no __init__.py fail. Those tests need to be removed.
- There are no tests yet.
