This is preparation for MDEV-12288, which would set DB_TRX_ID=0 when purging history. Also with that change in place, delete-marked records must always refer to an undo log record via a nonzero DB_TRX_ID column. (The DB_TRX_ID is only present in clustered index leaf page records.) btr_cur_parse_del_mark_set_clust_rec(), rec_get_trx_id(): Statically allocate the offsets (should never use the heap). Add some debug assertions. Replace some use of rec_get_trx_id() with row_get_rec_trx_id(). trx_undo_report_row_operation(): Add some sanity checks that are common for all operations that produce undo log. |

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