Python 2.6 & elementTree

[pcurry]

Greetings. I am trying to help a co-worker use AuthKit in our
environment. He claims that AuthKit specifically requires elementTree
1.2.6, rather than the one included with Python 2.6.

Could you point me to where the incompatibilities might lie, or why
there are not incompatibilities, that would be really helpful. Thank
you!

elementTree is a dependency of the OpenID libraries I believe so if you
aren't using them it shouldn't be a problem.

I'm sorry I didn't specify, we're using the 0.4.5 version of AuthKit.

Our plan was simply to alias in the elementTree implementation in Python 2.6.  We only saw the one import of elementTree, in authkit.authenticate.sso.api at line 16:

from elementTree import ElementTree

We changed that to:

from xml.etree import ElementTree

AuthKit imported fine.  The only use of the ElementTree we uncovered was in authkit.authenticate.sso.cas, at line 89:

            tree = ElementTree.fromstring(response)

which was unaffected by our change.  Though it does render AuthKit incompatible with Python 2.4.  To retain backwards compatibility, you could wrap the xml.etree call in an exception handler, and import elementTree from a third-party module if necessary.  It would certainly save trouble in Python 2.5 + environments.

Thanks for your response!
