Re: Testing HTTP/2 support in PHP

Hi Davey, Davey Shafik wrote:

However, Rasmus raised the possibility of adding HTTP/2 support to the cli-server [2], and (someone? @php-pulls) suggested we pull in a third party lib to do the heavy lifting [3]. My recommendation would be to use libnghttp2 [4] which curl also uses — however, as this adds a new dependency, I think it should be optional (e.g. --with-nghttp2-dir=[PATH]), with it falling back to the current HTTP/1.x implementation. We could also add a flag (e.g. --[no-]http2) on the CLI for enabling/disabling it — this would be helpful for testing HTTP/2 client fallback when it's not supported.

Hmm, this would mean a new dependency, and more potential complexity. I'm not sure if HTTP/2 justifies it. Also, don't all the major client implementations of HTTP/2 require TLS? Or is localhost given a free pass?

This is a much more useful tool than relying on node for make tests, and allows us to test adding HTTP/2 support to ext/curl, the HTTP stream (which could also use libnghttp2…), userland HTTP/2 clients, pecl_http (if that's still a thing), etc.

If added, I suppose it would be useful for PHP developers testing HTTP/2 features like Server Push, assuming the CLI server supported it. Thanks. -- Andrea Faulds https://ajf.me/
