Hullo List,

A few days ago it was noticed that the viewcvs on our server was showing a blank page. The apache logfile muttered something about not being able to find the SAPI module.

I compared various backup images, and found that overnight every .py file in /usr/share/python-support had been added again but as .pyc (see below).

I know nothing about the intricacies of python; it would seem this is the same time as it would have broken though. viewcvs and apache2 have upgraded in this time. Can anyone can give me a hint as to where to start foraging for incompatibilities? Presumably something didn't upgrade that should?

Here are the installed python-related packages (sorry to post loads of output)

Many thanks,

etc etc

Well sapi appears to be part of the viewcvs package

david@sid:/var/log/apache2$ dpkg -L viewcvs | grep sapi /usr/share/python-support/viewcvs/sapi.py

Do you have a PythonPath statement in the apache settings for viewcvs?

David, thanks.

The problem was eventually fixed with an update-python-modules -f

Thanks, Brett, for irc help as well.

Jenny
