Rust

Opendoas has a significantly smaller codebase. It only has 4397 lines of code compared to Sudo-rs’s staggering 35990 lines.

Hmm.

I too love making unaware "Tests Considered Harmful" arguments based on some blind analysis.

Funnily enough, one could easily do some actually potentially useful shallow analysis, instead of a completely blind one, simply by noticing the libc crate dependency, then running:

git grep -Enp -e libc:: --and --not -e '(libc::(c_|LOG)|\b(type|use)\b)'

Ignoring the usage in test modules, use of raw libc appears to be more than you would think from the title. One can also argue that some of that usage would be better served by using rustix instead of raw libc.

Of course authors can counter with arguments why using rustix* is not feasible or would complicate things, and would argue that the use of unsafe+libc is required for this kind of project, and it's still reasonably limited and contained.

And a little bit more informed back-and-forth discussion can go from there.

* Searching for rustix in the sudo-rs repo returned this. So this predictably has been brought up before.
