Due to the recent xz trouble I presume? Good idea, I was thinking about this on an ecosystem wise scale (e.g. all of crates.io or all of a Linux distro) which is a much harder problem to solve.
Not sure if the tag logic is needed though. I thought cargo embedded the commit ID in the published package?
Also I’m amazed that the name cargo-goggles was available.
Correct. To be clear, the xz vulnerability shows that this is just a very small step, but it will at least make git repo audits more useful since you will then know that the crates.io release matches.
Unfortunately, the git commit isn’t always available, either because of releases made with old versions of cargo, or because maintainers deliberately publish with cargo publish --allow-dirty or cargo hack --no-dev-deps
Yes, obviously there are more ways to hide malicious code.
As for the git commit ID, I didn’t see you using it even when it was available though? But perhaps that could be a weakness, if the commit ID used does not match the tag in the repo, that would be a red flag too. That could be worth checking.
I’m not completely sure what to do here because many crates seem to get published from the release PR branch, not the main one, so the commit id is usually unreliable anyway.
On one side I want something strict that can’t be easily bypassed, on the other if everything’s a red flag you’ll just ignore it
