For the old-style provider cache directory model we hashed the individual executable file for each provider. That's no longer appropriate because we're giving each provider package a whole directory to itself where it can potentially have many files. This therefore introduces a new directory-oriented hashing algorithm, and it's just using the Go Modules directory hashing algorithm directly because that's already had its cross-platform quirks and other wrinkles addressed during the Go Modules release process, and is now used prolifically enough in Go codebases that breaking changes to the upstream algorithm would be very expensive to the Go ecosystem. This is also a bit of forward planning, anticipating that later we'll use hashes in a top-level lock file intended to be checked in to user version control, and then use those hashes also to verify packages _during_ installation, where we'd need to be able to hash unpacked zip files. The Go Modules hashing algorithm is already implemented to consistently hash both a zip file and an unpacked version of that zip file. |
