[Zope] Limit transaction undo

[Joakim Nicander]

Hello!

We are using Zope for several customers where we built an interface to
maintain their own websites.
Working very well, but the ZODB will grow because of all saved transactions.

We don't need the saved transactions since we do all the production on
another server.

Today we manually pack the ZODB regularly, but it would be nice to either
stop or limit this feature. I have searched but haven't found any hint on
how to do this. Is it possible?

If not, is there a way to automatically pack the ZODB regularly?

Another odd thing is that I see transactions saved when a dtml-method has
been viewed. The method doesn't contain anything that do any changes to the
ZODB. But I need to do some more testing and learn how Zope handles
transactions before be absolutely sure.

Where can read more about how/what Zope saves transactions? The handbook
didn't go in to any details.
