1273.1.5	Remove last vestiges of savepoint_alloc_size, savepoint_offs... Remove last vestiges of savepoint_alloc_size, savepoint_offset, and SAVEPOINT struct.	Jay Pipes	14 years ago
1273.1.4	This patch significantly reworks the way that This patch significantly reworks the way that savepoints are handled: 1) Memory management Removes the trans_prealloc_size and trans_block_size variables which set up a separate mem_root for storing "savepoint data". Without the binlog, this separate memory root, which by default allocated 1M for every single transaction regardless of whether savepoints were used, was not useful any more. 2) No more DIY linked lists of SAVEPOINT pointers The Session::transaction struct used to contain a member "savepoints" which was of type pointer to SAVEPOINT. This has been replaced with an STL std::deque<drizzled::NamedSavepoint> and the pointeri and linked-list fiddling is gone, replaced with STL conventions. 3) SAVEPOINT struct is now drizzled::NamedSavepoint The SAVEPOINT struct has been converted to an STL container- safe class called drizzled::NamedSavepoint. 4) RollbackToSavepoint, Savepoint, and ReleaseSavepoint RollbackToSavepoint, Savepoint, and ReleaseSavepoint classes have had their logic revamped and documented. 5) The innodb.test case had (has?) an error in it The innodb.test case was testing a wrong assertion that a ROLLBACK TO SAVEPOINT x; should result in an error if called twice in a row. This is incorrect behaviour. If a ROLLBACK TO SAVEPOINT x; is executed, the savepoint x should stay on the top of the savepoint stack. 6) XID and XID_STATE classes made STL-container-safe Places proper initializer lists and constructors for the XID and XID_STATE classes and removes use of the horrible memset(this, 0, sizeof(*this)); usage. 7) The various savepoint-handling routines use references A switch was made to the various savepoint-handling routines of TransactionServices to ensure only references to a drizzled::NamedSavepoint were being passed, and not void pointers.

1273.1.3	Removes pointless ha_enable_transaction call. This wasn't u... Removes pointless ha_enable_transaction call. This wasn't used anywhere to any effect.	Jay Pipes	14 years ago
1273.1.2	This patch does not change any algorithms or code paths, This patch does not change any algorithms or code paths, it just moves the transaction-related methods in the drizzled/ha_commands.cc file into a file named drizzled/transaction_services.cc and creates a singleton Service class called TransactionServices containing all the previous ha_xxx methods related specifically to the XA distributed transaction processing model. This is a quick stopgap patch in the move towards separating out the XA Resource Manager API from the Storage Engine API.	Jay Pipes	14 years ago
1273.1.1	* Changes Session::warn_id to Session::warn_query_id * Changes Session::warn_id to Session::warn_query_id * Makes Session::query_id and Session::warn_query_id private members * Adds getters and setters for above members * Changes ReplicationServices::initTransactionMessage() to use Session::getQueryId() instead of Session::getTransactionId()	Jay Pipes	14 years ago
