Now the actual binlog position for each commit is stored in THD, and XtraDB can fetch the correct value from within commit_ordered() or commit(). mysql-test/r/group_commit_binlog_pos.result: Test case for XtraDB binlog position. mysql-test/t/group_commit_binlog_pos-master.opt: Test case for XtraDB binlog position. mysql-test/t/group_commit_binlog_pos.test: Test case for XtraDB binlog position. sql/log.cc: Save binlog position corresponding to commit in THD, and make accessible to storage engine. sql/sql_parse.cc: Add generic crash point for use in test cases. storage/xtradb/handler/ha_innodb.cc: Update to use new method of getting current binlog position that works with group commit. storage/xtradb/handler/ha_innodb.h: Update to use new method of getting current binlog position that works with group commit.
