Potential import collision: import path should be "go.etcd.io/bbolt", not "github.com/etcd-io/bbolt"

[KateGo520]

Background

I find that go.etcd.io/bbolt and github.com/etcd-io/bbolt coexist in this repo：
https://github.com/louketo/louketo-proxy/blob/master/go.mod （Line 12 & 27）

github.com/etcd-io/bbolt v1.3.3
go.etcd.io/bbolt v1.3.3 // indirect

That’s because the etcd-io/bbolt has already renamed it’s import path from "github.com/etcd-io/bbolt" to "go.etcd.io/bbolt". When you use the old path "github.com/etcd-io/bbolt" to import the bbolt, will reintroduces etcd-io/bbolt through the import statements "import go.etcd.io/bbolt" in the go source file of etcd-io/bbolt.

https://github.com/etcd-io/bbolt/blob/v1.3.3/cursor_test.go#L14

package bbolt_test
import (
	bolt "go.etcd.io/bbolt"
	…
) 

The "go.etcd.io/bbolt" and "github.com/etcd-io/bbolt" are the same repos. This will work in isolation, bring about potential risks and problems.

Solution

Follow the requirements of [etcd-io/bbolt README.md]https://github.com/etcd-io/bbolt/blob/v1.3.3/README.md:

To start using Bolt, install Go and run go get:
>$ go get go.etcd.io/bbolt/...
This will retrieve the library and install the bolt command line utility into your $GOBIN path.

Importing bbolt
To use bbolt as an embedded key-value store, import as:
>import bolt "go.etcd.io/bbolt"
…

Replace all the old import paths, change "github.com/etcd-io/bbolt" to "go.etcd.io/bbolt ".
