Resolve deadlock

[JustinObanor (Justin)]

Not sure why there’s a deadlock, even though the channel was closed, and i looped the amount of times needed

import (
	"fmt"
	"time"
)

func sth() {

	ticker := time.NewTicker(500 * time.Millisecond)

	done := make(chan bool)
	c := make(chan int)

	go func() {
		for i := 0; i < 10; i++ {
			select {
			case <-done:
				return
			case <-ticker.C:
				c <- i
			}
		}
		close(c)
	}()

	for i := 0; i < 10; i++ {
		fmt.Println(<-c)
	}
	

	time.Sleep(1 * time.Second)
	ticker.Stop()
	done <- true
	fmt.Println("Ticker stopped")
}

func main() {
	sth()
}

Thats the full code.

Before executing the line done <-true, channel c and Ticker are both closed (ended) so this line blocks and try to transfer control to another task but there is none so that’s the reason you got the message “all goroutines are asleep”
