LOCK_thd_data was used to protect both THD data and ensure that the THD is not deleted while it was in use This patch moves the THD delete protection to LOCK_thd_kill, which already protects the THD for kill. The benefits are: - More well defined what LOCK_thd_data protects - LOCK_thd_data usage is now much simpler and easier to verify - Less chance of deadlocks in SHOW PROCESS LIST as there is less chance of interactions between mutexes - Remove not needed LOCK_thread_count from thd_get_error_context_description() - Fewer mutex taken for thd->awake() Other things: - Don't take mysys->var mutex in show processlist to check if thread is kill marked - thd->awake() now automatically takes the LOCK_thd_kill mutex (Simplifies code) - Apc uses LOCK_thd_kill instead of LOCK_thd_data |

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: https://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.

More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss and the #maria IRC channel on Freenode.
