Automatic merge from submit-queue Fix leaking goroutines in watch cache Fixes #38670 which causes leaked goroutines in the API server. The root cause is: if the WatchServer timeout [fires](https://github.com/kubernetes/kubernetes/blob/master/pkg/apiserver/watch.go#L187-L188) when the `result` channel is full, `sendWatchCacheEvent` will be blocked on the write to the `result` even though `cacheWatch.Stop()` is [called](https://github.com/kubernetes/kubernetes/blob/master/pkg/apiserver/watch.go#L171), because WatchServer stops consuming the `result` channel after the timeout. Thanks to @krousey for identifying the problem. cc @mml @yujuhong |
