Tracking issue: expand CI testing about socket2

[Thomasdezeeuw]

@Thomasdezeeuw I'm guessing it's more the OS than the architecture that you're interested in for the tier 2 targets?

Yes let's start with the OS. I think if we can run tests on all supported OSs, on any architecture, we can ensure the functionally works. Than cargo check would be enough for different architectures just to make the we got the libc definitions and functions right.

It looks like we might be able to use MacOS workers in GitHub Actions to run some of the BSDs. Alternatively, Travis CI does seem to support FreeBSD (although I can't find any docs on it), which we do still use in some repos here in rust-lang (specifically stdarch and stdsimd).

There is also https://cirrus-ci.org/ for FreeBSD, e.g. Mio uses the following file: https://github.com/tokio-rs/mio/blob/04050dbd87d7b79c33168c6a972a8bb35cf510f8/.cirrus.yml.

I believe WASI can be supported since their lib-c exposes sockets. I'd be interested in adding it.

cc @rust-lang/infra I think we have a few repos in rust-lang with fairly extensive CI suites. Can we think of any examples that we could use to bootstrap some broader CI here? I'm thinking particularly of iOS...

[Thomasdezeeuw]

@KodrAus, @rust-lang/infra a little update: tier 2 targets are now all cargo checked, but if it's possible to actually run the tests somehow I would prefer that.

Don't think there is much left to do here, so closing.

Sounds good @jkelleyrtp. Although last I check (I think version 9/10) WASI didn't allow for the creation of sockets, however that could have changed. In either case the various socket options could still be useful.
