This bug was originally spotted by using golangci-lint so I put it here to track the status because it affects this project too 🙂 It is caused by upstream dependency go-tools and I've created issue in respective repo dominikh/go-tools#806

Cheers!

Seems it was fixed, so we need to wait when the honnef.co/go/tools will release a new version, so unfortunately we cannot update to the master branch due an error with unused linter:

go run cmd/golangci-lint/main.go run --allow-parallel-runners --disable-all -Egosimple --no-config test_gosimple/...
# github.com/golangci/golangci-lint/pkg/golinters
pkg/golinters/unused.go:16:7: undefined: unused.NewChecker````

The list of liters from honnef.co/go/tools that will need an additional attention during an upgrade:

  • gosimple
  • statickcheck
  • stylecheck
  • unused

Hey @SVilgelm, the version honnef.co/go/tools v0.0.1-2020.1.5 is fixed and works as expected for the case reported in this issue. Moreover, this version is already in go.mod so I built golangci-lint from the newest commit and tested. Everything works as expected 🎉 hence after release, this can be closed. Thanks for your help 🙂

In newest golangci-lint v1.31.0 this bug doesn't exist, so issue is resolved and can be closed
