Due to this bug many queries that contained a window function with MIN/MAX aggregation returned wrong results. Calculation of a MIN/MAX aggregate function uses cache objects and a comparator object that are created and set up in Item_sum_hybrid::fix_fields () by a call of Item_sum_hybrid::setup_hybrid(). The latter binds the objects to the first argument of the MIN/MAX function. Meanwhile window function perform aggregation over fields of a temporary table. So binding must be done rather to these fields. The earliest moment when setup the objects used in MIN/max functions can be done is after all calls of the method split_sum_func(). This patch introduces this late setup, but only for aggregate functions used in window functions. Probably it makes sense to use this late setup for all MIN/MAX objects. |

MariaDB: drop-in replacement for MySQL
MariaDB is designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariadB Foundation and the MariaDB Corporation, and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at: http://mariadb.org/ https://mariadb.com/kb/en/ https://mariadb.com/kb/en/mariadb-vs-mysql-features/ https://mariadb.com/kb/en/mariadb-versus-mysql-features/ https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/
As MariaDB is a full replacement of MySQL, the MySQL manual at http://dev.mysql.com/doc is generally applicable.
