Ages ago, I found a documentation about the ZODB that details its transaction handling. I have remembered the essential facts but forgot where I have found the documentation. With your favorite search engine, you might be able to find it.... Alternatively, you can look at the source code for "transaction._transaction.Transaction.commit" or use Zope's "shared.DC.ZRDB.TM.TM" (the "TM" stands for "Transaction Manager"). The "TM" class is used to interface Zope's relational database adapters to the transaction system. To see how "TM" might be used, you can look at the implementation of a Zope database adapter. The "TM" use is traditionally found in a file called "db.py" ((almost) all adapters seem to have been copied from a common ancestor and then modified), e.g. "ZPsycopaDA/db.py". -- Dieter _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
