I'm 99.9% sure that version commit and abort are broken in ZODB.DB. The commit methods in CommitVersion, and AbortVersion (and TransactionalUndo) call invalidate on the databse too soon -- before the transaction has committed. This can have a number of bad effects, including causing inconsistent data in connections.
An argument for keeping version in the past was that they "worked". Well, I think they don't work and I'm not interested in writing the test to fix them. Is anyone else?
I will write the necessary tests to fix the undo bug. Jim -- Jim Fulton mailto:[EMAIL PROTECTED] Python Powered!
