when two different users want to commit changes made to the same object at the same time
In http://www.dieter.handshake.de/pyprojects/zope/zope.html#bct_sec_5.1: 'The ZODB usually guarantees that a transaction does not read inconsistent data by issuing a |ReadConflictError| when it tries to read an object from the ZODB that has been modified since transaction start. Zope usually restarts the transaction in this case.' I would guess so that: * Since there is no such thing as 'at the same time' ... * the /first/ client that will issue a commit will be fine * Without Dieter's patch, the /second/ one should fail because a |ReadConflictError will have been thrown | -- Gérard
