Set up golangci-lint linter based on gometalinter #670

ginywiny · 2021-08-07T00:14:51Z

Creating a new PR because the previous one had a weird amount of strange commit history which went over my head to squash despite the many attempts taken.

Test HIGHLY based on test-gometalinter, as it is used to lint the same files, except where golangci-lint is used instead of gometalinter.

Notes:

When golangci-lint uses the --skip-files flag, it still lints the file, but simply doesn't display the linting results.
The build fails because the revive linter has found issues with certain files. This is new as revive is a new linter being used to replace golint, as it runs more quickly. This will be fixed down the line.
Comments and TODOs from the previous gometalinter test file were kept in case new linters are being used.

What was done:

Updated make deps script to install golangci-lint
Created golangci-lint script based on test-gometalinter
Updated test script to run test-golangci-lint

I see:

./test.sh: line 34: ./test/test-golangci-lint.sh: Permission denied

Did you u+x the file? Where do you see the list of lint errors we expect?

ginywiny · 2021-08-09T20:00:59Z

@purpleidea Whoops, must've forgot to change that. Fixed it and squashed.
The list of errors are expected for the "revive" linter.

Great! Please rebase to master and force-push and let's see what happens. (I pushed some fixes.)

Patch looks good, just needs a few small changes.
Also check your $EDITOR, it's letting you save files without EOF newlines.

why is this version hardcoded? can we use the latest version? is there a safer way to do this so we don't pipe to shell? if not, please change this so it only runs in ci.

It is recommended to use a specific version as per the installation instructions (https://golangci-lint.run/usage/install/), to avoid introducing new linter errors from new minor or major releases. However, would it still be preferred to use the latest version?

I have changed this to something else. Any thoughts of it now?

are these five lines of comments valid?

Added these lines in case somebody were to move over any changes from gometalinter to golangci-lint. There were some linters which were entirely commented out, whereas some were still left as TODO, since they still require some fixes. More for clarity purposes, but they can be removed.

Are they still valid?

This is/will be removed in #671 so if that's merged first, this will need to be rebased and updated

Can you remove all of the gometalinter references from here and other places in the codebase?

I don't know what @purpleidea thinks about this, but it seems wise to run this check in Github Actions, at least when running in Github. Perhaps we can skip installation and running in GH and only do it in other CI systems? Then to provide the same functionality, drop in the relevant configuration into https://github.com/purpleidea/mgmt/blob/master/.github/workflows/test.yaml
https://golangci-lint.run/usage/install/#github-actions

To clarify (as explained on the linked page), this provides useful comments in PRs in context of where the issues are, instead of being hidden away in the actions tab

@ginywiny Want to rebase to newest master and fixup?

@purpleidea I will rebase and make a fix.
