Be careful what you do when you find that "isConnected()" returns false. Note, that, in general, it would be a bug to just reopen a new connection in this case: previous operations against the connection might have been lost without notice when you simply reopen a new connection and do as if nothing bad had happened. Instead, you should reopen the connection and then raise an exception similar to "ZODB.POSException.ConflictError". Hopefully, the publisher will handle this kind of exception correctly (by retrying the complete request). -- Dieter _______________________________________________ Zope3-dev mailing list Zope3firstname.lastname@example.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com
