Automatic merge from submit-queue. Manual cherrypick of #65034 to 1.9: make json serializer case sensitive fixes partially https://github.com/kubernetes/kubernetes/issues/64612 This PR imports the latest jsoniterator library so that case sensitivity during unmarshalling is optional. The PR also sets Kubernetes json serializer to be case sensitive. **Release note**: ```release-note ACTION REQUIRED: Kubernetes JSON deserializer is now case-sensitive to restore compatibility with pre-1.8 servers. If your config files contains fields with wrong case, the config files will be now invalid. ``` /sig api-machinery /kind bug /assign caesarxuchao liggitt thockin sttts mbohlool Kubernetes-commit: f4cf484c2cb6056e28fb9759a3c913be3eed990a
concurrent
- concurrent.Map: backport sync.Map for go below 1.9
- concurrent.Executor: goroutine with explicit ownership and cancellable
concurrent.Map
because sync.Map is only available in go 1.9, we can use concurrent.Map to make code portable
m := concurrent.NewMap()
m.Store("hello", "world")
elem, found := m.Load("hello")
// elem will be "world"
// found will be true
concurrent.Executor
executor := concurrent.NewUnboundedExecutor()
executor.Go(func(ctx context.Context) {
everyMillisecond := time.NewTicker(time.Millisecond)
for {
select {
case <-ctx.Done():
fmt.Println("goroutine exited")
return
case <-everyMillisecond.C:
// do something
}
}
})
time.Sleep(time.Second)
executor.StopAndWaitForever()
fmt.Println("executor stopped")
attach goroutine to executor instance, so that we can
- cancel it by stop the executor with Stop/StopAndWait/StopAndWaitForever
- handle panic by callback: the default behavior will no longer crash your application
