      MWL#136: Cross-engine consistency for START TRANSACTION WITH CONSISTENT SNAPSHOT · 7322e388
      unknown authored
      Make the binlog handlerton participate in START TRANSACTION WITH CONSISTENT
      SNAPSHOT, recording the binlog position corresponding to the snapshot taken
      in other MVCC storage engines.
      
      Expose this consistent binlog position as the new status variables
      binlog_trx_file and binlog_trx_position. This enables to get a fully
      non-locking snapshot of the database (including binlog position for
      slave provisioning), avoiding the need for FLUSH TABLES WITH READ LOCK.
      
      Modify mysqldump to detect if the server supports this new feature, and
      if so, avoid FLUSH TABLES WITH READ LOCK for --single-transaction
      --master-data snapshot backups.

      MWL#116: Code simplifications for TC_LOG_MMAP. · b91ad17c
      unknown authored
      Make TC_LOG_MMAP (and TC_LOG_DUMMY) derive directly from TC_LOG, avoiding the
      inheritance hierarchy TC_LOG_queued->TC_LOG_unordered.
      
      Put the wakeup facility for commit_ordered() calls into the THD class.
      
      Some renaming to get better names.

      Fix test failure (timeout) in --valgrind tests in Buildbot. · 4cb9a326
      unknown authored
      The main.ps_ddl test does SELECT * FROM mysql.general_log; that can be really
      expensive with --valgrind if previous test cases put lots of data in the
      general log since last server restart. Fix by truncating the log at test start.

      MWL#116: Efficient group commit: Fix bug that binlog pos stored by XtraDB during commit was wrong when more than one commit in group.
      
      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().

        Save binlog position corresponding to commit in THD, and make accessible to storage engine.

        Add generic crash point for use in test cases.

      MWL#116: Efficient group commit · 8bc44536
      unknown authored
      Tweak the commit_ordered() semantics. Now it is only called for transactions
      that go through 2-phase commit. This avoids forcing engines to make commits
      visible before they are durable.
      
      Also take LOCK_commit_ordered() around START TRANSACTION WITH CONSISTENT
      SNAPSHOT, to get a truly consistent snapshot.
