This would happen especially in optimistic parallel replication, where there is a good chance that a transaction will be rolled back (due to conflicts) after it has executed record_gtid(). If the transaction did any deletions of old rows as part of record_gtid(), those deletions will be undone as well. And the code did not properly ensure that the deletions would be re-tried. This patch makes record_gtid() remember the list of deletions done as part of a transaction. Then in rpl_slave_state::update() when the changes have been committed, we discard the list. However, in case of error and rollback, in cleanup_context() we will instead put the list back into rpl_global_gtid_slave_state so that the deletions will be re-tried later. Probably fixes part of the cause of MDEV-12147 as well. Signed-off-by: Kristian Nielsen <knielsen@knielsen-hq.org> |

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. More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss and the #maria IRC channel on Freenode. *************************************************************************** NOTE: MariaDB is specifically available only under version 2 of the GNU General Public License (GPLv2).
