示例1: UpdateWorkUnit
// UpdateWorkUnit causes some state change in a work unit. If the
// work unit is pending, this is the principal interface to complete
// or renew it; if it is already complete this can cause it to be
// retried.
func (jobs *JobServer) UpdateWorkUnit(
workSpecName string,
workUnitKey string,
options map[string]interface{},
) (bool, string, error) {
// Note that in several corner cases, the behavior of this as
// written disagrees with Python coordinated's:
//
// * If neither "lease_time" nor "status" is specified,
// Python coordinated immediately returns False without
// checking if workUnitKey is valid
//
// * Python coordinated allows arbitrary status changes,
// including AVAILABLE -> FINISHED
//
// * This openly ignores "worker_id", as distinct from Python
// coordinated, which logs an obscure warning and changes it,
// but only on a renew
