Golangci-lint: Goimports regression after v1.12.4

[sagikazarmark]

During the latest update of my local golangci-lint binary (from 1.12.3 to 1.12.5) I started to receive an error for package github.com/hashicorp/go-getter: File is notgoimports-ed

The package name of go-getter is actually getter which is used in the source file.

Tried with 1.12.4 as well, so I think it's safe to say this is the version where the regression has been introduced.

Version of golangci-lint: golangci-lint has version 1.12.5 built from 609de32 on 2018-12-23T09:40:14Z

Hi!
These warnings came from the newest version of goimports (from this commit). Do you use the latest one (go get -u golang.org/x/tools/cmd/goimports)? What behavior did you expect?

[sagikazarmark]

I use prebuilt binaries of golangci, currently downgraded to 1.12.3.

I expect that the linter does not complain when the package path (github.com/hashicorp/go-getter) and the package name (getter) don't match.

[daenney]

I got the same issue in CI where we use the pre-built binaries GolangCI is providing. I wasn't aware I then have to manually update goimports or the other linters it depends on?

[sagikazarmark]

Me neither. I'd find it quite odd.

[jirfag]

You don't need to use external goimports. Golangci-lint doesn't depend on it. You may do it just to compare and ensure that golangci-lint is in sync with upstream goimports.

Also you can fix the issue in all files by running something like:

go get -u golang.org/x/tools/cmd/goimports
find . -name "*.go" | fgrep -v vendor/ | xargs goimports -w

P.S. We are planning to add option like --fix to golangci-lint to fix all goimports (and other linters) issues automatically).

[sagikazarmark]

Okay, so it looks like this is an intended change, not a bug after all. I thought this was some sort of configuration change, but after reading the commit, this looks pretty logical to me.

One thing though: it might make sense not to make these kind of updates in a patch version. Minor version is questionable as well, but that would be acceptable IMHO.

[sagikazarmark]

The main confusion came from Goland removing those aliases.
Looks like this is going to be fixed in 2019.1: https://youtrack.jetbrains.com/issue/GO-6146

[jirfag]

the idea of including this into the patch commit was that it's a bug we don't use the latest version of goimports. A few users reported that we are out of sync with goimports.
But you are right: better was to make a new minor release
