When a table is renamed to an internal #sql2 or #sql-ib name during a table-rebuilding DDL operation such as OPTIMIZE TABLE or ALTER TABLE, and shortly after that a purge operation in an index on virtual columns is attempted, the operation could fail, but purge would fail to release the table reference. innodb_acquire_mdl(): Release the reference if the table name is not valid for acquiring a meta-data lock (MDL). innodb_find_table_for_vc(): Add a debug assertion if the table name is not valid. This code path is for DML execution. The table should have a valid name for executing DML, and furthermore a MDL will prevent the table from being renamed. row_vers_build_clust_v_col(): Add a debug assertion that both indexes must belong to the same table. |
