[swift-server-dev] Prototype of the discussed HTTP API Spec

Hi all,

David here, working with Paulo on Zewo and more. There’s absolutely a lack of process, as Paulo mentioned. We have a very rough road ahead of us, with a ton of extra work, if we need to start writing implementation code at this level. Tests and dummy implementations should be well enough to allow us to gather feedback.

The way forward, as I see it, is agreeing on the API for HTTP Request/Response/Headers/Method/Status/Version based on a proposal structure and pull requests.

I should also mention that I strongly oppose bringing in dependencies from any actor in the Swift community to the work group org at this stage.

One of the advantages of this approach is that it widens the funnel of participation out from "API designers" to include users, who can try out the API and provide feedback.

That doesn't mean that your proposal is ignored - in fact it gives us an excellent list of areas that we can debate incrementally and see what the effect would be via working use cases and performance tests.

I really think we should move incrementally with well defined scopes and deadlines for every round. We didn't have that so far. Carl and others said that my suggestion is counter productive. I think the opposite, of course, as what I'm proposing is a well defined process where when we settle on a design for a particular set of base APIs then we move on to a higher absctraction. This way we won't be discussing the same things over and over again. I'll repeat, if we can't agree on the base types how can we move on? I'm saying let's first *settle* on Version, Headers, Message, Request and Response. Really *define* the API so then we move on, incrementally, from lower abstraction to higher abstraction.

I really don't want to discuss this over and over, ad infinitum. The most important in the messages I sent before is that we need a well defined process. We don't have it. Just taking the first implementation, with a lot of things that admitedly don't fit the scope, and adding that so we can rework doesn't feel right to me. I'm actually confused about the scope this project is taking. The code there explicitly mentions a WebApp, which is a higher responsibility than HTTP. When we started this project the scope as very clear. Crypto/TLS, Socket, HTTP. A well designed HTTP module shouldn't depend *at all* on the socket implementation. Providing an implementation would be just a matter of injecting a dependency. Moving that code as is to the org really doesn't feel right to me. All I'm saying is that we definitely should start having code on the org. But I say we move first Version, Headers, Message, Request, Response. And again, the "least controversial" I sent yesterday isn't radically strange. It's an evolution of Johaness original proposal, plus Carl's, plus Helge's suggestions, plus my suggestions. The only thing I added that wasn't discussed before is HTTPHeader.Field which does a case insensitive comparison in its equatable implementation, and the Message protocol which holds the properties common to request and response (version and headers). If we can't agree on that, which is the sum of everything that was discussed about these particular types. How can we agree on that full implementation?

It’s about a prototype implementation of an API that was already proposed and discussed a month and a half ago.  The prototype isn't a full-featured framework like Vapor or Kitura, but it does actually work and it even has XCTests with decent (>75%) code coverage.
