Until you pack the database.
For our application it would be useful to access these past states for
an object. I have in mind something along the lines of the wikipedia
History tab, which allows you to see what an object was like at a
given past instance.
The actual Undo functionality is not too important for the
application, and there are certainly users that I would want to be
able to view the past states but not be able to revert (undo) to it.
Since the undo data is already being stored it feels like I should be
able to tap into this to access the past states, without having to
actively store anything - does anyone have any hints on how I might go
A Zope object versioning system is more appropriate for this case.
One take is in the zope trunk now--maybe zope.app.versioning?
