* MDEV-7769 MY_CHARSET_INFO refactoring# On branch 10.2Alexander Barkov2016-10-101-5/+2

| | | | | | | | | PROCEDURE ANALYSE in UNION Reverting a part of the patch for "MDEV-8909union parser cleanup", as a parenthesized SELECT with PROCEDURE followed by UNION is not disallowed by the grammar (only a non-parenthesized SELECT with PROCEDURE followed by a UNION is disallowed grammatically).
* Fix assertion/hang in read_init_file()Kristian Nielsen2016-09-091-1/+12
| | | | | | | | | | | If there are other threads running (for example binlog background thread), then the thread count may not drop to zero at the end of do_handle_bootstrap(). This caused an assertion and missing wakeup of the main thread. The missing wakeup is because THD::~THD() only signals the COND_thread_count mutex when the number of threads drops to zero.

* | | | | MDEV-5535: Cannot reopen temporary tableNirbhay Choubey2016-06-101-10/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mysqld maintains a list of TABLE objects for all temporary tables created within a session in THD. Here each table is represented by a TABLE object. A query referencing a particular temporary table for more than once, however, failed with ER_CANT_REOPEN_TABLE error because a TABLE_SHARE was allocate together with the TABLE, so temporary tables always had only one TABLE per TABLE_SHARE. This patch lift this restriction by separating TABLE and TABLE_SHARE objects and storing TABLE_SHAREs for temporary tables in a list in THD, and TABLEs in a list within their respective TABLE_SHAREs.

It allows to replace easily one instance of such a list for another. Besides it will facilitate to compare two lists if they originate from the same window specification. In fact any direct assignment for objects of the type SQL_I_List<ORDER> was not valid.
| * | | | | | Initial patch for the implementation of window functions (MDEV-6115):Igor Babaev2016-02-121-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - All parsing problems look like resolved - Stub performing name resolution of window functions in simplest queries has been added.

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.

| * | | | | MDEV-717 LP:1003679 - Wrong binlog order on concurrent DROP schema and ↵Alexey Botchkov2016-03-231-46/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CREATE function. The cause of the issue is when DROP DATABASE takes metadata lock and is in progress through it's execution, a concurrently running CREATE FUNCTION checks for the existence of database which it succeeds and then it waits on the metadata lock. Once DROP DATABASE writes to BINLOG and finally releases the metadata lock on schema object, the CREATE FUNCTION waiting on metadata lock gets in it's code path and succeeds and writes to binlog.
