The github.com/usk81/generic
uses Go modules and the current release version is v2
. And it’s module path is "github.com/usk81/generic"
, instead of "github.com/usk81/generic/v2"
. It must comply with the specification of "Releasing Modules for v2 or higher" available in the Modules documentation. Quoting the specification:
A package that has opted in to modules must include the major version in the import path to import any v2+ modules
To preserve import compatibility, the go command requires that modules with major version v2 or later use a module path with that major version as the final element. For example, version v2.0.0 of example.com/m must instead use module path example.com/m/v2.
https://github.com/golang/go/wiki/Modules#releasing-modules-v2-or-higher
GO111MODULE=on, run go get
targeting any version >= v2.2.0 of the usk81/generic
:
$ go get github.com/usk81/[email protected]
go: finding github.com/usk81/generic v2.2.0
go: finding github.com/usk81/generic v2.2.0
go get github.com/usk81/[email protected]: github.com/usk81/[email protected]: invalid version: module contains a go.mod file, so major version must be compatible: should be v0 or v1, not v2
run go get github.com/usk81/generic
, the version will stuck in v2.1.0:
go: downloading github.com/usk81/generic v1.1.0
go: downloading github.com/usk81/generic v2.1.0+incompatible
go: github.com/usk81/generic upgrade => v2.1.0+incompatible
SO anyone using Go modules will not be able to easily use any newer version of usk81/generic
.
This would push them back to not being managed by Go modules (instead of incorrectly using Go modules).
Ensure compatibility for downstream module-aware projects and module-unaware projects projects
Patch the go.mod
file to declare the module path as github.com/usk81/generic/v2
as per the specs. And adjust all internal imports.
The downstream projects might be negatively affected in their building if they are module-unaware (Go versions older than 1.9.7 and 1.10.3; Or use third-party dependency management tools, such as: Dep, glide,govendor…).
If you don't want to break the above repos. This method can provides better backwards-compatibility.
Release a v2 or higher module through the major subdirectory strategy: Create a new v2 subdirectory
(github.com/usk81/generic/v2) and place a new go.mod file in that subdirectory. The module path
must end with /v2
. Copy or move the code into the v2 subdirectory. Update import statements
within the module to also use /v2
(import "github.com/usk81/generic/v2/…"). Tag the release with v2.x.y
.
If the standard rule of go modules conflicts with your development mode. Or not intended to be used as a library and does not make any guarantees about the API. So you can’t comply with the specification of "Releasing Modules for v2 or higher" available in the Modules documentation.
Regardless, since it's against one of the design choices of Go, it'll be a bit of a hack. Instead of go get github.com/usk81/generic@version-tag
, module users need to use this following way to get the usk81/generic
:
(1) Search for the tag
you want (in browser)
(2) Get the commit hash
for the tag
you want
(3) Run go get github.com/usk81/generic@commit-hash
(4) Edit the go.mod file to put a comment about which version you actually used
This will make it difficult for module users to get and upgrade usk81/generic
.
[*] You can see who will be affected here: [1 module user, e.g., usk81/go-dmm]

You can make a choice to fix DM issues by balancing your own development schedules/mode against the affects on the downstream projects.
