------------------------------------------------------------ revno: 2630.22.3 committer: Davi Arnaut <Davi.Arnaut@Sun.COM> branch nick: 4284-6.0 timestamp: Thu 2008-08-07 22:33:43 -0300 message: WL#4284: Transactional DDL locking Make transaction management more modular through a new interface. The overall objective of this change is to provide groundwork for the design of transactional DDL locking by cleaning up the transaction high level API to better distinguish operations implicit and explicit, and single statement transaction from operations on the normal transaction. Having a a high-level interface for transaction management provides a better base for implementing transactional concepts that are not always tied to storage engines and also makes it easier to interect with other higher level modules of the server.
