aergo-lib

This repository is a collection of common libraries used in the aergo project. See godoc to get more detail descriptions and usages.

config

Package config provides an easy way to create and manage configurations for aergo projects written in go.

db

Package db is an wrapper of database implementations. Currently, this supports badgerdb. More implementations (e.g. leveldb) will be updated in the future

log

Package log is a global and configurable logger pkg, based on zerolog

aergo-lib's Issues

BadgerDB logger seems to be broken in latest update

Hi, It seems like the latest update of Aergo-lib doesn't allow for BadgerDB instance to be created. Specifically, I can't create a BadgerDB instance without the lib panicing. This didn't happen in the previous version (v1.3.0).

I have a minimal code example to demonstrate this panic:

package main

import (
	"log"

	"github.com/aergoio/aergo-lib/db"
)

func main() {
	aergoDB, err := db.NewBadgerDB("data")
	if err != nil {
		log.Fatal(err)
	}
	defer aergoDB.Close()
}

Here is the panic that is generated:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x1562c12]

goroutine 1 [running]:

exit status 2

If it helps, the contents of the data dir after this panic is just a single file MANIFEST.

I believe this is probably related to the replacement of the badger default logger in edf758f, but I am currently not too familiar with the lib. Am I using this wrong (e.g. API changed), or does this look like a legitimate bug?

Thanks,
