This is the summary of the 12. week of my Google Summer of Code project: HTTP/2 prototype server implementation in node.js.
The main item that I got done this week was the upgrade to the latest draft of the spec: draft-ietf-httpbis-http2-06. This was a really smooth transition.
I had to rewrite a large part of the compression code, but that was expected. I have to say that I like the current version of the compression spec much better than previous versions. The text is much cleaner and it finally allows the building of a streaming header encoder and decoder implementation. The new implementation is therefore consists of a pair of transform streams that do the compression/decompression. The decompressor is in fact just buffering the input and then processing it in one large batch at the end, but fixing that is already on my todo list (issue #46). The next step would be exposing these streaming interfaces on the public API.
For the next week, I'd like to finally start implementing a HTTP/2 test page for browsers (using the to-be-done failure injection capability). It has been on the table for a long time now, but I think that the time has come to finally start working on this.
