劫持恐慌输出

Question

When my golang app is panicking, it is printing go routines stack trace and quiting. I wonder if there is nice way to get panic output for further processing. Redirecting stderr is not enough, because one would like to put some error logs there. I would like to get only panic output.

Answer 1

You can get a formatted stack trace using the runtime.Stack function. By passing true as the second argument, you can see stack traces of all gouroutines.
