Millistel juhtudel võib goroutine'is käivitatud ülesanne lisada plaanija globaaljärjekorda?

In Go, a task running in a goroutine can be added to the global scheduler queue in the following cases:

• When the goroutine is created with go: Calling go func() { ... }() creates a new goroutine and places it in the global scheduler queue for execution.

• If the current thread (M) is busy or overloaded: The scheduler can move the goroutine to the global queue to distribute the load among threads.

• When the goroutine is blocked: If the goroutine is waiting for a resource (e.g., a channel or timer), it can be suspended and, after being unblocked, added to the global queue.

• When the local scheduler queue is empty: The scheduler can take tasks from the global queue to balance the load.

Example of starting a goroutine:

func main() {
    go func() {
        fmt.Println("Hello from goroutine")
    }()
    time.Sleep(time.Second) // to give the goroutine time to execute
}

Here, the goroutine is immediately added to the global scheduler queue for execution.
