grpc-panic-handler
Taken from https://github.com/kazegusuri/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
