1.20.2 — diff review from 1.20.1 only (current) safe-to-deploy

From mozilla/supply-chain copy of hg. By Erich Gubler.

This update works around a Cargo bug that forces the addition of portable-atomic into a lockfile, which we have never needed to use.

The current version of OnceCell is 1.20.2.

cargo-vet does not verify reviewers' identity. You have to fully trust the source the audits are from.

safe-to-run

This crate can be compiled, run, and tested on a local workstation or in controlled automation without surprising consequences. More…

does-not-implement-crypto (implies crypto-safe)

Inspection reveals that the crate in question does not attempt to implement any cryptographic algorithms on its own.

Note that certification of this does not require an expert on all forms of cryptography: it's expected for crates we import to be "good enough" citizens, so they'll at least be forthcoming if they try to implement something cryptographic. When in doubt, please ask an expert.

crypto-safe
Implied by other criteria

All crypto algorithms in this crate have been reviewed by a relevant expert.

Note: If a crate does not implement crypto, use does-not-implement-crypto, which implies crypto-safe, but does not require expert review in order to audit for.

safe-to-deploy (implies safe-to-run)

This crate will not introduce a serious security vulnerability to production software exposed to untrusted input. More…

I reviewed this crate with default features. All code outside the sync module is simple and clearly correct, and the code in the sync module comes from std with minor changes.

Lib.rs has been able to verify that all files in the crate's tarball, except Cargo.lock, are in the crate's repository with a git tag matching the version. Please note that this check is still in beta, and absence of this confirmation does not mean that the files don't match.

Crates in the crates.io registry are tarball snapshots uploaded by crates' publishers. The registry is not using crates' git repositories, so there is a possibility that published crates have a misleading repository URL, or contain different code from the code in the repository.

To review the actual code of the crate, it's best to use cargo crev open once_cell. Alternatively, you can download the tarball of once_cell v1.20.2 or view the source online.
