[ZODB-Dev] Transaction

[Paolo Invernizzi]

Thank you for your kind answer Jeremy,

I've forgotten to mention I would like to try to implement it with 
ZODB4... ;-(
I think that I must implement IDataManager interface...
Must I subclass the database connection and add my 
prepare/abort/commit/savepoint stuff there (along calling the base 
prepare/abort/commit/savepoint)?
Or must I implement a new DataManager and (donno how and if it is 
possible) register the MyFile with it?

Thanks in advance for your patience.
