I have a question about golang preempt schedule, here is my example code;
I doubt why the bar groutine don't happen preempt schedule? (I build with
-gcflags “-N -l” to stop func inline)
More if my server with one or two cpu bound worker goroutine runing, when
the gc need stop the world, how it can stop the worker?
package main
import “time"
// GOMAXPROCS=1
var sum1 int64
func add1() {
for i := 0; i < 10000; i++ {
for j := 0; j < 10000; j++ {
sum1++
}
}
}
func bar() {
for {
add1()
}
}
func main() {
go bar()
time.Sleep(1*time.Second)
println("debug>>>")
}
