[go-nuts] Exported singleton in vendor is initialized on every call

[Rayland]

Greetings fellow gophers,

I have a library in my vendor folder that looks like this:

package gorm

import (
       "fmt"
       "github.com/jinzhu/gorm"
       _ "github.com/jinzhu/gorm/dialects/mysql"
       conf "github.com/spf13/viper"
       "math/rand"
       "time"
)

var DB *gorm.DB

func GetDB() (*gorm.DB, error) {
       if DB != nil {
              return DB, nil
       }

       DB_NAME := conf.GetString("db.sql.mysql.dbname")
       DB_USERNAME := conf.GetString("db.sql.mysql.username")
       DB_PASSWORD := conf.GetString("db.sql.mysql.password")
       DB_IPS := conf.GetStringSlice("db.sql.mysql.ips")
       ipsNr := len(DB_IPS)

       rand.Seed(int64(time.Now().Nanosecond()))

       connString := 
fmt.Sprintf("%s:%s@tcp(%s)/%s?charset=latin1&parseTime=True",
              DB_USERNAME,
              DB_PASSWORD,
              DB_IPS[rand.Intn(ipsNr)],
              DB_NAME,
       )

       DB, err := gorm.Open("mysql", connString)
       if err != nil {
              return nil, err
       }

       return DB, nil
}


And every time I use GetDB() I get a new database connection instead of 
getting the one already initialized. 

When I do the same thing outside the vendor folder it works as intended.

What's the catch here?


Thank you
