ReadView::copy_trx_ids(): Relax a debug check. It failed to account for TRX_STATE_PREPARED_RECOVERED, which was introduced in MDEV-15772. It was also reading trx->state twice and failed to tolerate TRX_STATE_COMMITTED_IN_MEMORY, which could be concurrently assigned in lock_trx_release_locks(), which is not holding trx_sys->mutex. This bug is specific to the MariaDB 10.2 series. The ReadView was introduced in MariaDB 10.2.2 by merging the code that had been introduced in MySQL 5.7.2. In MariaDB 10.3, ReadView::snapshot() would use the lock-free trx_sys.rw_trx_hash. MDEV-14638 moved the corresponding assertion to trx_sys_t::find(), where it was duly protected by trx->mutex, and later MDEV-14756 moved the check to rw_trx_hash_t::validate_element(). This check was correctly adjusted when MDEV-15772 was merged to 10.3. |

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.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.
