grpc-panic-handler

grpc-panic-handler is an interceptor to protect a process from aborting by panic and return Internal error as status code.

Usage

import (
	panichandler "github.com/kazegusuri/grpc-panic-handler"
)

func main() {
	uIntOpt := grpc.UnaryInterceptor(panichandler.UnaryPanicHandler)
	sIntOpt := grpc.StreamInterceptor(panichandler.StreamPanicHandler)
	grpc.NewServer(uIntOpt, sIntOpt)
}

Custom Panic Handler

You can write custom panic handler in case of panic. Use InstallPanicHandler.

func main() {
	panichandler.InstallPanicHandler(func(r interface{}) {
		fmt.Printf("panic happened: %v", r)
	}
}

Built-in custom panic handler

• LogPanicDump
• debug.Stack() to stderr
• LogPanicStackMultiLine
• show stack trace in multi line by glog
