How To dump the StackTrace When Receiving a SIGQUIT signal

dump_stack.go

// Thanks to zeebo on #go-nuts
package main

import (
	"os"
	"os/signal"
	"runtime"
	"syscall"
)

func dumper() {
	in := make(chan os.Signal)
	signal.Notify(in, syscall.SIGQUIT)
	var buf [4096]byte
	for _ = range in {
		n := runtime.Stack(buf[:], true)
		os.Stdout.Write(buf[:n])
	}
}

// kill -QUIT <pid> to see stack 

func main() {
	//called syncly so that main doesn't exit
	dumper()
}
