site.py not compatible with python 2.7

[leoliu]

We use python 2.7 exclusively and it is a surprise to discover today that site.py in all virtual envs with python 2.7 use py2.6's site.py which lacks many new functions added in python 2.7.

[qwcode]

can you give an example of what is not working for you?

site.getsitepackages() doesn't work.

Reproduced on OS X:

$ virtualenv -p python2.7 ve
$ ./ve/bin/python -c 'import site; print(getattr(site, "getsitepackages"))'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute 'getsitepackages'

Running outside venv works for me -

$ python -c 'import site; print(getattr(site, "getsitepackages"))'
<function getsitepackages at 0x104198410>``` 

$ ./ve/bin/python -c 'import site; print(site.file)'
/private/tmp/ve/lib/python2.7/site.pyc
$ python -c 'import site; print(site.file)'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.pyc

We ship our own `./virtualenv_embedded/site.py`

Consider updating (and ensuring backwardly compat) site.py

I don't think this should be marked as a release blocker. although it would be great to support feature-compatible site.py files, this shortcoming has been like this for years.

" this shortcoming has been like this for years". And hell yeah, it still hurts... :(
Consider fixing this plz, thx

This bit me today; it would be really, really nice to get an updated site.py included in virtualenv since the old 2.6 version doesn't have things like site.getusersitepackages().
