"Re-factor the code for post-join operations". The patch mainly contains the code ported from mysql-5.6 and created for two essential architectural changes: 1. WL#5558: Resolve ORDER BY execution method at the optimization stage 2. WL#6071: Inline tmp tables into the nested loops algorithm The first task was implemented for mysql-5.6 by Ole John Aske. It allows to make all decisions on ORDER BY operation at the optimization stage. The second task implemented for mysql-5.6 by Evgeny Potemkin adds JOIN_TAB nodes for post-join operations that require temporary tables. It allows to execute these operations within the nested loops algorithm that used to be used before this task only for join queries. Besides these task moves all planning on the execution of these operations from the execution phase to the optimization phase. Some other re-factoring changes of mysql-5.6 were pulled in, mainly because it was easier to pull them in than roll them back. In particular all changes concerning Ref_ptr_array were incorporated. The port required some changes in the MariaDB code that concerned the functionality of EXPLAIN and ANALYZE. This was done mainly by Sergey Petrunia. |
