If I remember correctly, though, there was still a lot in question about legitimate use cases. The web-services cluster-safety use-case I sketched out here (http://mail.zope.org/pipermail/zope3-dev/2002-October/003112.html) is still (perhaps) a valid case, but ONLY in a very-carefully constructed application (and even that case leaves me wanting a better app-level way to do it).
I think I agree with the feeling that versions should stay in ZODB, but be depreciated/marked as "official evil" in ZMI.
As you and Guido are talking about the ZMI (which means, AFAIK, the managament interface), let me just say that as far as I understand it, deprecating/marking-as-evil and even removing OFSP/Version.py is not what I would like to see happen (not only). The problem lies in ZODB.ZApplication.ZApplicationWrapper def __bobo_traverse__(self, REQUEST=None, name=None): db, aname, version_support = self._stuff if version_support is not None and REQUEST is not None: version=REQUEST.get(version_support,'') else: version='' conn=db.open(version) ... As I understand it, even if the Version product is removed, just putting at variable named 'Zope-Version' into the REQUEST will cause reads and writes to happen in a version. Am I missing something here? cheers, oliver
