[Zope-dev] Turn-off undo.

[Kevin Dangoor]

Hi,

You can't exactly "turn off undo". This is a feature of the FileSystem
storage. Even if undo were removed, the FileSystem storage works by
appending all changes to the end of the file, so it would keep growing and
growing.

There are a couple of solutions. One: you can use BerkeleyStorage instead of
FileSystem Storage. That storage (available on Zope.org) doesn't support
undo, and also doesn't grow wildly when changes are made to objects.

Two: you can store all of your poll results in an SQL database.

For future development, I'd also recommend looking at ZPatterns... with
that, you'll be able to implement some things in ZODB and others in SQL and
have it all be pretty transparent to applications.
