[PATCH] sandbox.py replaces builtin type file with builtin function open
This is a copy of http://bugs.python.org/setuptools/issue59:
builtin open changed from an alias to the file type to a function in Python 2.5. sandbox.py assumes file is open when replacing/restoring the two with sandboxed versions
Attached is a patch that removes that hardcoding
Prioritized as critical, this is evil!
