Hi, Is there a way to renew a context that has already reached a deadline?
package main
import (
"context"
"fmt"
"time"
)
func sleepAndPrint(ctx context.Context, msg <-chan string, b <-chan bool) {
for {
select {
case <-ctx.Done():
fmt.Println("Context Done", ctx.Err())
// if ctx.Err() != nil //// renew (if count < 5) <<<<<<<<!?
case m := <-msg:
fmt.Println("msg", m)
case <-b:
return
}
}
}
func main() {
b := make(chan bool)
d := time.Now().Add(1 * time.Second)
ctx, cancel := context.WithDeadline(context.Background(), d)
//ctx, cancel := context.WithCancel(context.Background())
defer cancel()
c := make(chan string, 1)
go sleepAndPrint(ctx, c, b)
msgs := []string{"hi", "how", "are", "you"}
for _, v := range msgs {
c <- v
}
time.Sleep(4 * time.Second)
//b <- true
}
