[Ironpython-users] __package__

It happens in Importer.cs - there's a comment saying "// explicit relative import, calculate and store __package__"

It also happens in imp.new_module, when creating the sys module, and in PythonContext.CreateBuiltinModule, but I think those are all much less interesting.

Import bugs are really tough...  Anyone who has worked on the importer code has never looked at the CPython source code to see how it works - so there's subtle issues like this.  I'd suggest looking at CPython where it sets it and then making IronPython work the same.

Subject: [Ironpython-users] __package__

Currently, I am working on implementing zipimport. I have modules being imported from egg files (very early and not a lot of testing done yet), but I notice that the __package__ attribute is not getting set up correctly, e.g.:

Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win
Type "help", "copyright", "credits" or "license" for more information.
>>> import oauth
>>> dir(oauth)
['__builtins__', '__doc__', '__file__', '__loader__', '__name__', '__package__',

IronPython 3.0 DEBUG ( on .NET 4.0.30319.237
Type "help", "copyright", "credits" or "license" for more information.
>>> import oauth
>>> dir(oauth)
['__builtins__', '__doc__', '__file__', '__loader__', '__name__', '__path__']

I see in the code that there are references to __package__, but following where it it set is proving to be a bit difficult. Can someone point me in the right direction?
