failure-checker should say which packages failed to publish

[sofisl]

Failure checker tells me some releases may have failed, but not which:
googleapis/google-cloud-node#3975

I went through and manually confirmed which ones didn't release, but it would be great if the bot could say it in the description (specifically for monorepos).

This is not really feasible. The bot does not have access to logs nor should it be able to parse them to determine what failed.

How does failurechecker determine that something was not published?

The reason I ask is because failurechecker keeps opening up issues for a given release (googleapis/google-cloud-node#3898) that it thinks didn't succeed, and every time I close it it reopens it because it accurately determines I must have missed one: https://github.com/googleapis/google-cloud-node/issues?q=is%3Aissue+is%3Aclosed+warning%3A+a+recent+release+failed. I thought this was because failurechecker was checking against a given package manager to see if the package was published, but if not, then maybe this reopening is a bug with failure checker that just happens to be right? shrug

Ok, I think this is actually a broken-clock-is-right-twice-a-day bug. I've confirmed that all the packages in this release have been published, and yet failurechecker keeps opening up a new bug. See latest here: googleapis/google-cloud-node#3981 (but there are many open for the same release)

Talked to Ben, seems like I need to remove the autorelease: failed label.
