This is for people who've implemented ZODB data managers. Data managers are components that manage persistent data under transaction control,
We've recently tried to clean up and document the data-manager interfaces. In addition, over the weekend, I implemented savepoints and was able to simplify the interfaces quite a bit. See IDataManager and ISavePointDatamanager in:
In particular, note that:
- The subtransaction APIs have disappeared fro data managers, and
- tpc_begin no longer takes a second "subtransaction" argument.
I *could* try to provide support for data managers with tpc_begin taking 2 arguments, but I'm guessing that I don't need to. I'm guessing that no one has written data managers that require a second argument. If this is not true and you have a data manager that requires a second argument that I need to support, please let me know.
