All tablespace metadata is buffered in fil_system. There is a LRU mechanism, but that only controls the opening and closing of fil_node_t::handle. It is much more efficient and less error-prone to access data file names by looking up the fil_space_t object rather than by essentially joining each row with an access to SYS_DATAFILES via the InnoDB internal SQL parser. dict_get_first_path(): Declare static. The function may only be needed when loading or updating the data dictionary. Also, change a condition in order to avoid a bogus GCC 10 -Wstringop-overflow warning for mem_strdupl() about len==ULINT_UNDEFINED. i_s_sys_tablespaces_fill_table(): Do not access other InnoDB internal dictionary tables than SYS_TABLESPACES. |
