how is the listening goroutine supposed to exit in the example? #229
Description
https://godoc.org/github.com/fsnotify/fsnotify#example-NewWatcher
watcher, err := fsnotify.NewWatcher()
if err != nil {
log.Fatal(err)
}
defer watcher.Close()
done := make(chan bool)
go func() {
for {
select {
case event := <-watcher.Events:
log.Println("event:", event)
if event.Op&fsnotify.Write == fsnotify.Write {
log.Println("modified file:", event.Name)
}
case err := <-watcher.Errors:
log.Println("error:", err)
}
}
}()
err = watcher.Add("/tmp/foo")
if err != nil {
log.Fatal(err)
}
<-doneIf say the watcher closes, the listening goroutine would not close, it would just remain open forever printing zero valued errors/events.
What is the correct way to use the API to ensure the goroutine exits when the watcher is closed?
