Okay this is now working for me locally.

Thanks!

@ioquatix do you mind addressing the linter failure? https://github.com/bryanp/llhttp/actions/runs/13664554845/job/38204178670?pr=32

[ioquatix]

Yes sure, those lines were me debugging the server tests. I've removed them.

[ioquatix]

This PR also changes the minimum Ruby version. Hopefully that is okay?

[bryanp]

Can it be dropped down to 3.0? This gem is used by http.rb which still depends on 3.0: https://github.com/httprb/http/blob/1af3c8e2dfb84d73e7febaaffce7bd7f4829cced/http.gemspec#L28

If that's an issue I can open a PR over there to try and bump it next release.

[ioquatix]

My suggestion would be to skip those tests on older Ruby versions, as there is nothing intrinsically problematic about the code in lib.

[bryanp]

The issue is that you bumped the minimum ruby version in the gemspec to 3.1—doesn't that make new releases of this gem incompatible with http.rb?

[ioquatix]

Yes, you'd need to revert the changes I made to the gemspec, and then only pull in async for the tests on Ruby 3.1+. Are you able to get this PR across the finish line?

[bryanp]

Yeah will do, thanks again for your help.

[ioquatix]

Great! Well done.
