Hi masters,
As far as I know, go 1.19 supports self-adaptive stack size when spawning a
goroutine, which intends to decrease the calling times of morestack that
aims to claim more frames from heap.
After each GC happens, Go runtime will calculate the average stack usage
and the next time, goroutine would created with such a stack size.
My question is, how do we validate the whole process or check it if works
well or not.
Is there any metric or stack size checking function, or should I use pprof
to peek the alloc part ?
Kindly thanks for all
```
func main() {
go func() {
// spawn a goroutine started from a fixed stack size
}()
runtime.GC()
go func() {
// spawn a goroutine started from an avg stack size.
}()
}
```
