I think some specific interleaving execution of `Invoke` and `Destroy` may lead to panic: |Invoke|Destroy|Description| |-------|---------|------------| |di.closed.Load() / di.reqNum().Load()<0||return false because destroy has not been called| ||di.closed.Store(true)|| ||di.reqNum.Load() == 0|return true because no reqNum has been added in invoke| ||di.reqNum.Add(-1)|| ||di.client = nil|set di.client to nil| |di.reqNum.Add(1)||| |di.client.Request||may panic because di.client is nil|| |di.reqNum.Add(-1)||| ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
