We audit crates for vulnerabilities on CI already. Lacking a lockfile means the audit is meaningless if the dependency versions can change between subsequent runs because of a e.g. minor or patch semver fix of a security vulnerability. There are advantages and disadvantages to having deterministic dependencies: Advantages: - Aforementioned auditing - Bisectability - More predictable behavior when binaries are installed with `cargo install --locked ...`. Disadvantages: - Cargo's dependency resolution can end up duplicating transitive dependencies in downstream crates which use a `rust-vmm` dependency that shares dependencies with more than one of the others. This can be inspected with `cargo-tree`. - Requires extra maintainer attention and effort to keep the lockfile up-to-date. The Rust Cargo team currently recommends against committing the lockfile for library crates in version control, but plans to reverse this recommendation in the future. You can read the new Cargo recommendations in the Nightly version docs: * https://doc.rust-lang.org/nightly/cargo/faq.html#why-have-cargolock-in-version-control * Web snapshot in Internet Archive: http://web.archive.org/web/20230921033901/https://doc.rust-lang.org/nightly/cargo/faq.html#why-have-cargolock-in-version-control Signed-off-by: Manos Pitsidianakis <manos.pitsidianakis@linaro.org>

I was thinking that with a committed lock file we will also get more dependabot PRs because then updates to patch/minor release will also need to be specifically done, they'll no longer be picked up by default. I guess since we're also doing batch dependabot updates that's not such a big concern. WDYT? |
