Hi all:
Our lab has been fighting against a problem recently with owfs and python 2.6.
We had been happily using python 2.5 and owfs p22 for quite some time.
Its been nice and stable, and life was good. Unfortunately, we had a
new piece of code that required us to upgrade our python system. Ever
since upgrading to 2.6, our attempts at running our software blow up.
Our software engineer on the project traced the blow-up to when he
called an owfs function. The blow-up is a recursion depth problem,a
nd in the process, it only sees one OW device on our network now.
So, first thing we did: upgraded to the latest version of owfs (p39),
and retry. Unfortunately, the behavior is the same. We're at a loss,
as we have stripped out as much of our code as possible.
I'm currently trying to get a dev machine going on python2.5 again to
try and concretely nail down the problem, but for the moment, this is
what I have. Any suggestions?
Here's sample output:

Any suggestions on this?
