If r_1 has privilege, r_2 doesn't have, and has relationship like r_1 -> r_2 -> user, user should have privilege to visit db.

Do you mean user has role r_2
r_2 has role r_1 ?
I think activeRoles contains both r_1 and r_2 ? @imtbkcat

ctx.ActiveRoles just contain r_1, you could use MySQLPrivileges.FindAllRole to get r_1 and r_2.
