Problem: ======== SHOW BINLOG EVENTS FROM <pos> causes a variety of failures, some of which are listed below. It is not a race condition issue, but there is some non-determinism in it. Analysis: ======== "show binlog events from <pos>" code considers the user given position as a valid event start position. The code starts reading data from this event start position onwards and tries to map it to a set of known events. Each event has a specific event structure and asserts have been added to ensure that read event data satisfies the event specific requirements. When a random position is supplied to "show binlog events command" the event structure specific checks will fail and they result in assert. Fix: ==== The fix is split into different parts. Each part addresses either an ASAN issue or an assert/crash. **Part1: Checksum based position validation when checksum is enabled** Using checksum validate the very first event read at the user specified position. If there is a checksum mismatch report an appropriate error for the invalid event. |

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).
