      Bug#55375 Transaction bigger than max_binlog_cache_size crashes slave · b6682591
      authored
      When slave executes a transaction bigger than slave's max_binlog_cache_size,
      slave will crash. It is caused by the assert that server should only roll back
      the statement but not the whole transaction if the error ER_TRANS_CACHE_FULL 
      happens. But slave sql thread always rollbacks the whole transaction when
      an error happens.
                  
      Ather this patch, we always clear any error set in sql thread(it is different
      from the error in 'SHOW SLAVE STATUS') and it is cleared before rolling back
      the transaction.

      Bug#56822: Add a thread state for sessions waiting on the query cache lock · 76643a46
      Davi Arnaut authored
      The problem was that threads waiting on the query cache lock
      are not easily seen due to the lack of a state indicating that
      the thread is waiting on the said lock. This made it difficult
      for users to quickly spot (for example, via SHOW PROCESSLIST)
      a query cache contention problem.
      
      The solution is to update the thread state when the query cache
      lock needs to be acquired. Whenever the lock is to be acquired,
      the thread state is updated to "Waiting for query cache lock"
      and is reset once the lock is granted or the wait is interrupted.
      The intention is to make query cache related hangs more evident.
      
      To further investigate query cache related locking problems, one
      may use PERFORMANCE_SCHEMA to track the overhead associated with
      the locking bits and determine which particular lock is being a
      contention point.
