cargo-goggles: verify that crates.io releases can be reproduced from the git repository
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-dirtyorcargo hack --no-dev-depsYes, 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.
