这些是mgo的相同版本/发行版吗？

Question

I have found two places of the mongodb driver in Go

• http://godoc.org/gopkg.in/mgo.v2 and http://godoc.org/gopkg.in/mgo.v2/bson
• http://godoc.org/labix.org/v2/mgo and http://godoc.org/labix.org/v2/mgo/bson

Are they the same distribution and version of mongodb driver in Go?

Why are there two pathnames for the same package?

Which one of the two shall I use?

Thanks.

Answer 1

You can find more information in the official page. The page links

gopkg.in/mgo.v2

From what I can see, labix.org/v2/mgo is probably the version 1 of the driver, whereas gopkg.in/mgo.v2 is the new version.

Go doesn't have traditional package distribution or versioning. Therefore, if you need a major refactoring and you want to break backward-compatibility, a common approach is to publish a different version at a different path.

I guess that's what happened here.
