all go routines are asleep - deadlock

Question

I don\'t understand why the deadlock is occurring in this code. I\'ve tried several different things to get the deadlock to stop (several different versions using WorkGroup)

Answer 1

You never close the "truck" channel ch, so UnloadTrucks never returns.

You can close the channel after all workers are done, by using a WaitGroup:

go func() {
    wg.Wait()
    close(ch)
}()
UnloadTrucks(ch)
