In case a table accessed by a PS/SP is dropped after the first execution of PS/SP and a view created with the same name as a table just dropped then the second execution of PS/SP leads to allocation of a memory on SP/PS memory root already marked as read only on first execution. For example, the following test case: CREATE TABLE t1 (a INT); PREPARE stmt FROM "INSERT INTO t1 VALUES (1)"; EXECUTE stmt; DROP TABLE t1; CREATE VIEW t1 S SELECT 1; --error ER_NON_INSERTABLE_TABLE EXECUTE stmt; # (*) DROP VIEW t1; will hit assert on running the statement 'EXECUTE stmt' marked with (*) when allocation of a memory be performed on parsing the view. Memory allocation is requested inside the function mysql_make_view when a view definition being parsed. In order to avoid an assertion failure, call of the function mysql_make_view() must be moved after invocation of the function check_and_update_table_version(). It will result in re-preparing the whole PS statement or current SP instruction that will free currently allocated items and reset read_only flag for the memory root. |

Code status:
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 and the MariaDB corporation. 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 Corporation, the MariaDB Foundation 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:
https://mariadb.com/kb/en/mariadb-vs-mysql-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/
https://mariadb.com/kb/en/library/new-and-old-releases/
As MariaDB is a full replacement of MySQL, the MySQL manual at http://dev.mysql.com/doc is generally applicable.
Help
More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss and the #maria IRC channel on Freenode.
Live QA for beginner contributors
MariaDB has a dedicated time each week when we answer new contributor questions live on Zulip and IRC. From 8:00 to 10:00 UTC on Mondays, and 10:00 to 12:00 UTC on Thursdays, anyone can ask any questions they’d like, and a live developer will be available to assist.
New contributors can ask questions any time, but we will provide immediate feedback during that interval.
