@pubiu can you post a protofile that reproduces this?

@pubiu can you post a protofile that reproduces this?

package handlers

import (
    "core/example-service/hook"
    "core/example-service/svc"
    "fmt"
    "os"
    "os/signal"
    "syscall"

    env        string // run environment
    configFile string
)

func init() {
    flag.StringVar(&env, "e", "local", "running environment")
    flag.StringVar(&configFile, "c", "", "config file")
}

func InterruptHandler(errc chan<- error) {
    c := make(chan os.Signal, 1)
    signal.Notify(c, syscall.SIGINT, syscall.SIGTERM)
    terminateError := fmt.Errorf("%s", <-c)

    // Place whatever shutdown handling you want here

    errc <- terminateError
}

func SetConfig(cfg svc.Config) svc.Config {
    return cfg
}

This code causes a running panic

zaquestion commented 2 years ago

@pubiu that's not the code causing the panic, it's something in ./proto/service.proto which seems to not be parsing correctly. Perhaps you figured it out and that's why you closed the ticket? Otherwise I'll need to .proto file to debug further.
