Hi again.
Did you perhaps intend to make the call to monitorWorker() as a goroutine?
That would let it run in parallel with the rest of main.

Hi Abhi.
I believe that the wait group timeout (in monitorWorker) was set to 2 seconds
in the code you posted.
I put a debugging print in the timeout case, and it is taking place.
What were you expecting to see?

hi John
Thanks for the reply
sorry
I mean Work2 takes => 3 seconds
work1 takes => 1 seconds
Wait group timeout is => 1 seconds
It is expected that only Work1 should get done and Work 2 should get timeout
which is not happening
Waitgroup waits for both work.. program doing something wrong
func Work2(message chan *TestStruct, wg *sync.WaitGroup, tokenNumber string) {
defer wg.Done()
v1 := new(TestStruct)
v1.Name = tokenNumber
time.Sleep(3 * time.Second)
message <- v1
fmt.Printf("finished %s\n", tokenNumber)
}
Thanks,
Abhi

Ø Work 2 - have 3 second
I’m not sure exactly what you are trying to do, but I suspect that changing
“messges” to hold 2 items might make it work.
messges := make(chan *TestStruct, 2)
I’m guessing, but I suspect that you didn’t realize that if Work1 runs first,
then Work2 will block since the channel is full (or until you close it).
