[Python-Dev] PEP 405 (built-in virtualenv) status

[Kristján Valur Jónsson]

Hi Carl.
I'm very interested in this work.
At CCP we work heavily with virtual environments.  Except that we don't use virtualenv because it is just a pain in the neck.  We like to be able to run virtual python environments of various types as they arrive checked out of source control repositories, without actually "installing" anything.
For some background, please see:  http://blog.ccpgames.com/kristjan/2010/10/09/using-an-isolated-python-exe/.  It's a rather quick read, actually.

The main issue for us is: How to prevent your local python.exe from reading environment variables and running some global site.py?

There are a number of points raised in the above blog, please take a look at the "Musings" at the end.

Best regards,

Kristján

Thanks for the report! I've added this to the list of open issues in the PEP and I'll look into it.
