      MDEV-7424: InnoDB: Assertion failure in thread 139901753345792 · fe0112e2
      Jan Lindström authored
        in file buf0mtflu.cc line 439
      
        Analysis: At shutdown multi-threaded flush sends a exit work
        items to all mtflush threads. We wait until the work queue is
        empty. However, as we did not hold the mutex, some other thread
        could also put work-items to work queue.
      
        Fix: Take mutex before adding exit work items to work queue and
        wait until all work-items are really processed. Release
        mutex after we have marked that multi-threaded flush is not
        anymore active.
      
        Fix test failure on innodb_bug12902967 caused by unnecessary
        info output on xtradb/buf/buf0mtflush.cc.
      
         Do not try to enable atomic writes if the file type
         is not OS_DATA_FILE. Atomic writes are unnecessary
         for log files. If we try to enable atomic writes
         to log writes that are stored to media supporting
         atomic writes we will end up problems later.

      MDEV-7273 - 10.1 fails to start up during tc_log initializations on PPC64 · f65901ee
      Sergey Vojtovich authored
      log-tc-size is 24K by default. Page size is 64K on PPC64. But log-tc-size
      must be at least 3 x page size. This is enforced by TC_LOG_MMAP::open()
      with a comment: to guarantee non-empty pool.
      
      This all makes server not startable in default configuration on PPC64.
      
      Autosize log-tc-size, so that it's min value= page size * 3, default
      value= page size * 6, block size= page size.

      wsrep_status was renamed to wsrep_info. Adjusted deb build scripts accordingly.

      MDEV-7364 - mysqld --help --verbose prints random values for "debug" · db89dd3a
      Sergey Vojtovich authored
      getopt value pointer of "debug" variable was pointing to incorrect address:
      &global_system_variables. Runtime statements like SHOW VARIABLES materialize
      value from DBUG structures on demand, so they never access getopt value pointer.
      But mysqld --help --verbose loaded this value from &global_system_variables.
      
      Remove "debug" variable from mysqld --help --verbose output by setting value
      pointer to NULL.

      MDEV-162 Enhanced semisync replication · 0b87de12
      Jonas Oreland authored
      Implement --semi-sync-master-wait-point=AFTER_SYNC|AFTER_COMMIT.
      
      When AFTER_SYNC, the semi-sync wait will be done earlier, before the storage
      engine commit rather than after. This means that a transaction will not be
      visible on the master until at least one slave has received it.

      MDEV-7257: Dump Thread Enhancements · 4d8b346e
      Jonas Oreland authored
      Make the binlog dump threads not need to take LOCK_log while sending
      binlog events to slave. Instead, a new LOCK_binlog_end_pos is used
      just to coordinate tracking the current end-of-log.
      
      This is a pre-requisite for MDEV-162, "Enhanced semisync
      replication". It should also help reduce the contention on LOCK_log on
      a busy master.
      
      Also does some much-needed refactoring/cleanup of the related code in
      the binlog dump thread.
