Quick and dirty annotations for Go stack traces
Aug 3, 2015Filippo Valsorda

Summary
This post introduces a technique for improving the debuggability of Go stack traces by converting IPv4 addresses to their uint32 representation and passing this as a blank identifier parameter to goroutines. This allows engineers to quickly identify which network interface a specific goroutine is listening on by examining the stack trace, significantly aiding in troubleshooting issues within their large-scale Go applications like RRDNS.
