Interesting. This looks good to me, but I will leave this open for @simonpasquier as he has also been involved in prometheus/prometheus#5621.

Thanks @carlosedp.

Ideally the bump should be done in the upstream repositories for anything that is an indirect dependency as it would benefit other consumers of those modules too.

[simonpasquier]

From github.com/miekg/dns, this repository hasn't yet moved to Go modules but it's in progress (miekg/dns#980).

[simonpasquier]

From github.com/prometheus/client_golang/prometheus which is already enabled for Go modules.

[simonpasquier]

From github.com/PuerkitoBio/purell (via github.com/go-openapi/spec) which isn't Go modules ready.

@simonpasquier actually the bump only added an indirect reference to x/sys. The tools and crypto were already there.
I might take a look if those require bumps as well later.
Do you think we can proceed here?

Hey @simonpasquier , can I rebase this PR?

[simonpasquier]

@carlosedp go ahead!

[carlosedp]

@simonpasquier done! Some weird error on test_frontend...

[simonpasquier]

Yes see #2013, you'll need to rebase after it merges.

[carlosedp]

Ah, ok. I'll wait till it's merged.

[simonpasquier]

It's merged 😏

[carlosedp]

I've rebased but still errors....

[simonpasquier]

It was a CI glitch. I've removed the go 1.13 directive from go.mod and it should be ok to merge on green.

[simonpasquier]

Thanks!

[carlosedp]

Thanks for the merge and sorry about the 1.13 directive!
