1273.1.27	Completes the work of removing the weirdness around transact... Completes the work of removing the weirdness around transaction boundaries in the storage engine API. * Transactional storage engines are now all explicitly notified of the start of a new "normal" transaction in the new PSE API method plugin::TransactionalStorageEngine::doStartTransaction() This new method takes a start_transaction_option_t as one of its parameters, and passing this option allows the storage engine API to cleanly signal the start of a consistent snapshot (and in the future additional transaction attributes). This meant the removal of the old start_consistent_snapshot() method. * The TransactionServices component now fully manages the transaction boundaries, notification of transaction boundaries to participating resource managers (transactional storage engines) Adds a simple test case (to be expanded with future XA work) for transaction behaviour.

1273.1.15	This patch completes the first step in the splitting of This patch completes the first step in the splitting of the XA resource manager API from the storage engine API, as outlined in the specification here: http://drizzle.org/wiki/XaStorageEngine * Splits plugin::StorageEngine into a base StorageEngine class and two derived classes, TransactionalStorageEngine and XaStorageEngine. XaStorageEngine derives from TransactionalStorageEngine and creates the XA Resource Manager API for storage engines. - The methods moved from StorageEngine to TransactionalStorageEngine include releaseTemporaryLatches(), startConsistentSnapshot(), commit(), rollback(), setSavepoint(), releaseSavepoint(), rollbackToSavepoint() and hasTwoPhaseCommit() - The methods moved from StorageEngine to XaStorageEngine include recover(), commitXid(), rollbackXid(), and prepare() * Places all static "EngineVector"s into their proper namespaces (typedefs belong in header files, not implementation files) and places all static methods corresponding to either only transactional engines or only XA engines into their respective files in /drizzled/plugin/ * Modifies the InnoDB "handler" files to extend plugin::XaStorageEngine and not plugin::StorageEngine The next step, as outlined in the wiki spec page above, is to isolate the XA Resource Manager API into its own plugin class and modify plugin::XaStorageEngine to implement plugin::XaResourceManager via composition. This is necessary to enable building plugins which can participate in an XA transaction without having to have that plugin implement the entire storage engine API	Jay Pipes	14 years ago
