zope2instance has to set software home

[Wichert Akkerman]

ploneout trunk is horribly broken at the moment. A Zope startup fails with ImageFile unable to find images. This is the root cause for that:

(Pdb) p getConfiguration().softwarehome
'/Users/wichert/Development/instances/ploneout/src/Products.CMFPlone'

softwarehome is set in App.FindHomes:

try:
    home = os.environ['SOFTWARE_HOME']
except KeyError:
    home = os.path.abspath(package_home(Products.__dict__))

Now that we have more Products.* eggs this will not work unless we set SOFTWARE_HOME.

This is a bit tricky since we can not set SOFTWARE_HOME from zope.conf and insisting on having it in the environment everywhere is tedious. I have a workaround though:

Index: FindHomes.py

 try:
     home = os.environ['SOFTWARE_HOME']
 except KeyError:
- home = os.path.abspath(package_home(Products.__dict__))
+ import Zope2
+ home = os.path.abspath(package_home(Zope2.__dict__))

     home, e = os.path.split(home)
     d, e = os.path.split(home)

This gets around the problem by basing the path on something that is guaranteed not to be a namespace but always located inside the Zope2 software home.
