keystone tests fail unless tox is configured "just so"

[Doug Hellmann]

As discussed on IRC:

[Mon 03:49:43 PM] <dhellmann> I'm trying to package keystone from master, and run the tests. In order to run the tests in the virtualenv I'm creating, I change tox.ini to set a couple of variables differently: http://paste.openstack.org/show/76559/
[Mon 03:49:50 PM] <dhellmann> morganfainberg: yeah
[Mon 03:50:02 PM] <dhellmann> it seems that setting usedevelop=False breaks that function
[Mon 03:50:14 PM] <morganfainberg> oh oh i see how it could.
[Mon 03:50:15 PM] <morganfainberg> doh*
[Mon 03:50:41 PM] <dhellmann> because it finds a path for the module with a full path, and the / becomes a . and then import complains that '.home.whatever.some.long.path' has an empty module name
[Mon 03:50:45 PM] <dhellmann> at the front there
[Mon 03:51:33 PM] <dhellmann> morganfainberg: so we could fix it a couple of ways, either by doing more smart work with the paths, or by converting those modules to be loaded with stevedore
[Mon 03:51:44 PM] <dhellmann> morganfainberg: before I submit a patch, I thought I'd see which you all would prefer
[Mon 03:51:47 PM] <morganfainberg> dhellmann, the latter would be better
[Mon 03:52:15 PM] <morganfainberg> dhellmann, i would rather use stevedore for all of our backends eventually, it makes sense that the tests should be the same
[Mon 03:52:16 PM] <dhellmann> ok, I concur, but didn't know if there was some reason it was done this way to begin with
[Mon 03:52:38 PM] <morganfainberg> dhellmann, we haven't converted stuff to stevedore yet, afaict that is the reason

    Fix the "search for sql.py" files for db models

    Fix the search logic for sql.py files for the db model import so
    that reflection created schemas are consistent.

    This does not mitigate the need to move to stevedore in the future
    for loading of backends / tests, but does solve the immidiate problem.
