Several packages are only used while running the e2e suite. These packages are less important to update, as the they can not influence the final executable that is part of the Ceph-CSI container-image. By moving these dependencies out of the main Ceph-CSI go.mod, it is easier to identify if a reported CVE affects Ceph-CSI, or only the testing (like most of the Kubernetes CVEs).

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
