New pypi override breaks people who override pypi

The OpenStack build farm has a decently complicated set of things it does to make sure that ~/.pip/pip.conf and ~/.pydistutils are set. The new hack_home_env code subverts that and is causing build failures in our build farm because it's causing things to actually talk to pypi.python.org, which we generally don't want to happen. BUT - we do not set pypi.openstack.org in our tox.ini files because we don't want devs running at home to be hitting our mirror.

Can we add a flag that allows disabling this behavior? We could work around it by just setting TOX_INDEX_URL in the env - but there are times when we construct this:

[global]
index-url = http://pypi.openstack.org/openstack
extra-index-url = http://pypi.python.org/simple

For things that are not official, and therefore not covered by our mirror.

Monty, Marcus,

I've uploaded a tox-1.6.1 release candidate to my development index:

http://devpi.net/hpk/dev/+simple/

You can use it with "-i" to install tox-1.6.1. I'd be grateful if
you can verify it works for you. The final 1.6.1 may still change
but not in this area.

best,
holger

fix issue116: make 1.6 introduced behaviour of changing to a
per-env HOME directory during install activities dependent
on "--set-home" for now. Should re-establish the old behaviour.

Yes, currently $HOME is set to a pseudo-location ({envtmpdir}) during installation of dependencies. While i want to get tox to perform more isolation in the future this change shouldn't have made it to 1.6.0.

so, to be clear, in 1.6, ~/.pip/pip.conf is ignored completely due to the HOME change?

FYI I plan to back the change out by making it depend on an option. And release a 1.6.1... Pending on camping place network connectivity :-)

more things:

a) you might want to look into http://devpi.net to simplify your index setup (and remove the need for "extra-index".

b) You might want to check if the new testenv install_command setting could help.

c) i am open to a command line option to disable/control the hack-home setting

d) sorry for the troubles

Could you add a -i ALL=our_index_url to the tox invocation? (it will set pip.conf/pydistutils.cfg in the pseudo home). As to extra-url, that would need to be added to tox, i think.

(note i am off for two weeks vacation so no or slow responses now)
