Why is this Go code blocking?

Question

I wrote the following program:

package main

import (
    \"fmt\"
)

func processevents(list chan func()) {
    for {
        //a := <-list
        //a()
         


        

Answer 1

Here is another solution - use range to read from the channel. This code will yield to the scheduler correctly and also terminate properly when the channel is closed.

func processevents(list chan func()) {
    for a := range list{
        a()
    }
}
