- What I did

go1.12.3 (released 2019/04/08) fixes an issue where using the prebuilt binary releases on older versions of GNU/Linux led to failures when linking programs that used cgo. golang/go#31293

see: https://github.com/golang/go/issues?utf8=✓&q=milestone%3AGo1.12.3

This change is because of no newline at end of file.

as @thaJeztahsaid,

I'm actually thinking of removing this "pin by digest", as it doesn't add much for our use-case 🤔

I also agree very much. Do we need to remove this "pin by digest" ? 🤔

[thaJeztah]

I am ok with removing it

It seems that the lint task failed, I ran the lint task locally and found that it takes 4m+.

/go/src/github.com/docker/cli # time /usr/local/bin/gometalinter --config=gometalinter.json ./...
real 4m 55.06s
user 1m 55.14s
sys 0m 26.43s

should we increasing deadline? 🤔

And I found gometalinter has been archived by the owner. alecthomas/gometalinter#590

should we change to use golangci-lint or other active lint tool?

Thanks!

Left one question about the timeout, and let's wait for the others to reply wrt the digest

For the linter: I just recalled there's a pull request to replace it (that I didn't review yet 🤭🤫😳) #1797

[thaJeztah]

Interesting;

WARNING: deadline exceeded by linter unused (try increasing --deadline)

Sorry, I didn't notice its existence. I just tried to change gometalinter to golangci-lint locally. 😆
