website: x/vgo, x/lint subrepos are 404

[dmitshur]

https://golang.org/x/vgo and https://golang.org/x/lint are 404 right now. That means godoc.org can't display their docs, and they can't be fetched with go get, etc.

They used to work recently. I don't know when exactly they stopped working. The other subrepos are fine.

There are still entries for them at https://github.com/golang/tools/blob/c1def519f03ddf76f16b3e444ee1095d73afa01b/cmd/godoc/x.go#L35 and https://github.com/golang/tools/blob/c1def519f03ddf76f16b3e444ee1095d73afa01b/cmd/godoc/x.go#L50, so I'm guessing it's related to the version of godoc deployed right now.

Did the master branch get deployed, then the release branch deployed (reverting the x/link change)?

This needs to be cherry-picked back to release branch probably.

/cc @FiloSottile too.

@andybons mentioned while fixing #25022 that he had to fix the deploy scripts to use the release branch, so probably yeah.

Many CI tests which use x/lint failed now.

golang/lint#397

It breaks the world.

[andybons]

On it.

[gopherbot]

Change https://golang.org/cl/109095 mentions this issue: [release-branch.go1.10] cmd/godoc: add x/lint and x/vgo redirects

[oiooj]

The service is normal now. Maybe we need monitor these services.

Fix has been deployed. I apologize for the downtime. Will follow up with monitoring so that we can catch this sooner in the future.

@bradfitz from golang/lint#397 (comment) with context, for anyone curious:

The original lint & vgo redirects were accidentally deployed from the master branch. They were never cherry-picked to the release branch. When golang.org was redeployed later from the release branch (correctly), it effectively reverted the lint redirects.

https://golang.org/cl/109095 does the necessary cherry-pick to the release branch.
