When MySQL 5.7 introduced indexed virtual columns, it introduced several bugs into the online table-rebuilding ALTER, that is, the row_log_table_apply() family of functions. The online_log format that was introduced for online table-rebuilding ALTER in MySQL 5.6 should be sufficient. Ideally, any indexed virtual column values would be evaluated based on the log records in the temporary file. There is no need to log virtual column values. (For ADD INDEX, that is row_log_apply(), we always must log the values of the keys, no matter if the columns are virtual.) Because omitting the virtual column values removes any chance of row_log_table_apply() working with indexed virtual columns, we will for now refuse LOCK=NONE in table-rebuilding ALTER operations when indexes on virtual columns exist. This restriction would be lifted in MDEV-14341. innobase_indexed_virtual_exist(): New predicate, to determine if indexed virtual columns exist in a table definition. ha_innobase::check_if_supported_inplace_alter(): Refuse online rebuild if indexed virtual columns exist. rec_get_converted_size_temp_v(), rec_convert_dtuple_to_temp_v(): Remove. row_log_table_delete(), row_log_table_update(, row_log_table_insert(): Remove parameters for virtual columns. trx_undo_read_v_rows(): Remove the col_map parameter. row_log_table_apply(): Do not deal with virtual columns. |

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.
