Go Time out con Interrupt e poi Kill


Esempio

c := exec.Command(name, arg...)
b := &bytes.Buffer{}
c.Stdout = b
c.Stdin = stdin
if err := c.Start(); err != nil {
    return nil, err
}
timedOut := false
intTimer := time.AfterFunc(timeout, func() {
    log.Printf("Process taking too long. Interrupting: %s %s", name, strings.Join(arg, " "))
    c.Process.Signal(os.Interrupt)
    timedOut = true
})
killTimer := time.AfterFunc(timeout*2, func() {
    log.Printf("Process taking too long. Killing: %s %s", name, strings.Join(arg, " "))
    c.Process.Signal(os.Kill)
    timedOut = true
})
err := c.Wait()
intTimer.Stop()
killTimer.Stop()
if timedOut {
    log.Print("the process timed out\n")
}
