Run more linters with golangci-lint
Currently we run only golint and gofmt. We should at least enable linters which are enabled by default in golangci-lint:
$ golangci-lint help linters
Enabled by default linters:
deadcode: Finds unused code [fast: true, auto-fix: false]
errcheck: Errcheck is a program for checking for unchecked errors in go programs. These unchecked errors can be critical bugs in some cases [fast: true, auto-fix: false]
gosimple (megacheck): Linter for Go source code that specializes in simplifying a code [fast: true, auto-fix: false]
govet (vet, vetshadow): Vet examines Go source code and reports suspicious constructs, such as Printf calls whose arguments do not align with the format string [fast: true, auto-fix: false]
ineffassign: Detects when assignments to existing variables are not used [fast: true, auto-fix: false]
staticcheck (megacheck): Staticcheck is a go vet on steroids, applying a ton of static analysis checks [fast: true, auto-fix: false]
structcheck: Finds unused struct fields [fast: true, auto-fix: false]
typecheck: Like the front-end of a Go compiler, parses and type-checks Go code [fast: true, auto-fix: false]
unused (megacheck): Checks Go code for unused constants, variables, functions and types [fast: false, auto-fix: false]
varcheck: Finds unused global variables and constants [fast: true, auto-fix: false]
Enabling some of them (I've checked errcheck and deadcode) would require fixing outstanding issues.
Work here should be done incrementally, one-by-one.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
@bitcodr that's great to hear. I think the best way to proceed is to pick up one of the linters from above (e.g. deadcode of errcheck), enable it and fix all reported issue and send me a PR for a review.
Hey @bitcodr Are you perhaps still working on this? If so feel free to /assign this issue. I was just looking for places to contribute and didn't know if this issue was taken or not. Thanks.
@oxddr Cleared errors for few of the modules, need some help on "clusterloader2" on few errors,
ERRO Running error: deadcode: analysis skipped: errors in package: [.../perf-tests/clusterloader2/pkg/chaos/nodes.go:109:52: cannot use k.client (variable of type kubernetes.Interface) as kubernetes.Interface value in argument to util.GetSchedulableUntainedNodes: wrong type for method AdmissionregistrationV1 .../perf-tests/clusterloader2/pkg/chaos/nodes.go:114:52
@satishbellapu - this looks strange. But let's work iteratively on it. Feel free to send a PR that is fixing just some of the errors. And then the pattern should be:
- extend the presubmit to check gofmt, but make it not fail the test (just informative)
- we will be working on fixing it while having it running
- once we fix everything, we will make it blocking
I didn't see any actions from @satishbellapu for last month, so it seems fine.
Hi @wojtek-t with https://github.com/kubernetes/perf-tests/pull/1448, we will have six outstanding linters running with golangci-lint. Apart from them I would like to suggest staticcheck & goimport to be enabled, what do you suggest do we need them or we are fine without them?
