[ZODB-Dev] propose to change undo support in ZEO
I'm working on improving the zeo architecture to make it perform better. Undo is causing some problems. For storages that support undo *and* work with ZEO, I'd like to add a new method, transaction_oids, that returns the oids modified by a transaction. Currently AFAIK, there are only 2 storages that work with ZEO and support undo, FileStorage and DirectoryStorage. I'm not 100% that DirectoryStorage still works with ZEO. I propose to add a new interface that includes this new method and require this interface to support undo with ZEO. This will break undo support for DirectoryStorage in ZEO, but I doubt that anyone will care.
