Bug#20777 Function w BIGINT UNSIGNED shows diff. behaviour with and without --ps-protocol
- Stored procedures returning unsinged values returns signed values if text protocol is used. The reason is that the stored proceedure item Item_func_sp wasn't initializing the member variables properly based on the information contained in the associated result field. - The patch is to upon field-item association, ::fix_fields, initialize the member variables in appropriate order. - Field type of an Item_func_sp was hard coded to MYSQL_TYPE_VARCHAR. This is changed to return the type of the actual result field. - Member function name sp_result_field was refactored to the more appropriate init_result_field. - Member function name find_and_check_access was refactored to sp_check_access.
