DB_COL_APPEARS_TWICE_IN_INDEX: Remove. This condition is already checked and reported by MySQL before passing the index definition to the storage engine. row_create_index_for_mysql(): Remove the redundant check for DB_COL_APPEARS_TWICE_IN_INDEX. When enforcing the column prefix index limit, invoke dict_mem_index_free(index) to plug the memory leak. In the loop, use index->n_def instead of dict_index_get_n_fields(index), because the latter would be 0 for indexes that have not been copied to the data dictionary cache. innodb-use-sys-malloc.test: Add test cases for attempting to trigger the error checks in row_create_index_for_mysql(). Before MySQL 5.5 and WL#5743, the leak is only reproducible if ha_innobase::max_supported_key_part_length() returned a higher limit than the one used in row_create_index_for_mysql(). In MySQL 5.5 and later, the leak is reproducible with innodb_large_prefix=true. rb:688 approved by Jimmy Yang |
