Ever since MDEV-5800 enabled indexed virtual columns for InnoDB, the InnoDB shutdown relied on close_connections() that would set thd->killed for the InnoDB purge threads. Alas, the embedded server shutdown is not invoking close_connections(), and thus InnoDB purge threads fail to initiate shutdown, causing a hang. innodb_inited: Remove. Use srv_was_started instead. innobase_fast_shutdown: Remove. Use srv_fast_shutdown instead. srv_running: Renamed from thd_destructor_myvar, and made global. The value NULL means that shutdown was requested or the purge threads should not be running because of innodb_read_only_mode=1. innobase_init(): Set srv_was_started after ensuring that srv_running was initialized. (In innodb_read_only mode, the purge threads are not started and we do not care if srv_running==NULL.) innobase_start_or_create_for_mysql(): Do not set srv_was_started. Let it be set by the only caller innobase_init(). srv_purge_should_exit(): Check also srv_was_started and srv_running when evaluating thd->killed.
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.
