I wrote a simple example of stopping go rutines. But I think that this can be implemented better.
Please see my code
package main
import (
"fmt"
"time"
)
var chans = map[string]chan int{
"test1":make(chan int),
"test2":make(chan int),
"test3":make(chan int),
"test4":make(chan int),
"test5":make(chan int),
}
func main() {
stop1 := make(chan int, 1)
go task("test1", stop1)
go task("test2", stop1)
go task("test3", stop1)
go task("test4", stop1)
go task("test5", stop1)
stopRoutines(stop1)
for {
select {
case t1 := <-chans["test1"]:
if t1 == 1 {
fmt.Println("Routine task1 stopped ")
}
case t2 := <-chans["test2"]:
if t2 == 1 {
fmt.Println("Routine task2 stopped ")
}
case t3 := <- chans["test3"]:
if t3 == 1 {
fmt.Println("Routine task3 stopped ")
}
case t4 := <-chans["test4"]:
if t4 == 1 {
fmt.Println("Routine task4 stopped ")
}
case t5 := <-chans["test5"]:
if t5 == 1 {
fmt.Println("Routine task5 stopped ")
}
default:
fmt.Println(len(stop1))
time.Sleep(3 * time.Second)
fmt.Println("------------")
}
}
}
func task(name string, stop chan int) {
fmt.Println("Task running")
for {
select {
case s := <-stop:
if s == 1 {
chans[name] <- 1
stop <- 1
return
}
default:
fmt.Println("task1")
time.Sleep(1 * time.Second)
}
}
}
func stopRoutines(stop chan int) {
time.Sleep(5 * time.Second)
fmt.Println("Signal stop for all routines")
stop <- 1
}
