test fails without feature tls12

[jonassmedegaard]

One test requires feature tls12, or it fails like this:

error[E0425]: cannot find value `TLS12` in module `rustls::version`

What test command are you running?

[jonassmedegaard]

Sorry, I forgot to copy that and no longer have that build log lying around - but it was likely cargo test --all-targets --no-default-features.

I am packaging this crate for Debian, and run tests in various feature combinations.

This one-line fix solved the issue for me: https://salsa.debian.org/debian/rust-tokio-rustls/-/blob/debian/latest/debian/patches/1001_tls12.patch

Good catch, would you like to open a PR?

[jonassmedegaard]

Thanks for the kind suggestion, but no - for political reasons: Github Terms of Service arguably contains a special licensing clause which is not problematic for liberally licensed code like this project but effectively weakens stronger copyleft licensed code. I therefore never push code to Github.

I already shared the code change as a patch. Please tell me if helpful to you that I provide it as a git branch that you can clone and merge. I fully understand if you have no interest in playing along with my policital game, though.

Anyone else feel like fixing this?

I notice that a new release went out, without this getting fixed :-(
