Go channels and deadlock

Question

I\'m trying to understand the Go language. I tried to create two goroutines that chain the flow between them using two channels:

func main() {
c1 := make(cha         


        

Answer 1

nmichaels is right on with his answer, but I thought I'd add that there are ways to figure out where you're deadlocking when debugging a problem like this.

A simple one is if you're on a Unix-like OS, run the command

kill -6 [pid]

This will kill the program and give a stack trace for each goroutine.

A slightly more involved way is to attach gdb.

gdb [executable name] [pid]

You can examine the stack and variables of the active goroutine as normal, but there's no easy way to switch goroutines that I know of. You can switch OS threads in the usual way, but that might not be enough to help.
