    Description

      alter online table t order by f;

      mysqltest: At line 2: query 'alter online table t order by f' failed: ER_ALTER_OPERATION_NOT_SUPPORTED_REASON (1846): LOCK=NONE is not supported. Reason: COPY algorithm requires a lock. Try LOCK=SHARED

      If it's expected, it needs to be documented, I didn't find it so far.
