Subject: [IronPython] Embedding CPython Messes with the IronPython 2 Import
Mechanism
Hello Guys,
Not sure what is going on here, nor whether it indicates a bug in
IronPython, but it is certainly odd. Loading a CPython interpreter
through the Python.NET assembly seems to change the IronPython (2a5)
import machinery.
I have a test module 'xyzz.py' that has an unused name 'wibble'.
Unsurprisingly, attempting to import this into IronPython 2.0a5 raises a
name error:

I'm not sure what's going on here - I've pinged the CLR dev who owns this
feature. In some patches (at some point) post v2.0.50727.42 there were some
changes made to Ref.Emit w.r.t. ModuleBuilder's vs. Modules - this looks like
it could be a regression related to those changes. But I don't understand the
big picture here.
As a work around you might be able to run in -X:GenerateAsSnippets mode. In
v2.0 this results in about a 10% perf degrade (last time I measured at least,
and this was against Pystone) but stops us from generating types to create
modules. So ultimately we won't create an assembly and won't go down this code
path. Of course, that may just be putting off the inevitable.
Another possiblity might be grepping Python.NET to see if they're doing
anything weird w/ Module or Assembly objects, although I wouldn't know exactly
what to look for.
