HTTP Parser

Dear Lazyweb, please write a XS module which interfaces to Mongrel's HTTP Parser (also seen in Thin). I'll buy you dimsum!

Sure, why not

Hmm, I might take a crack at it.

That state language compiler sure generates some nasty C code though!

Has an XS HTTP Header parser on CPAN.

Yeah I looked at that once, but it doesn't give you an HTTP::Request object or anything nice like that.

What we also need is a fast HTTP body parser in C, our HTTP::Body module in Catalyst is really slow for doing things like multipart body parsing. Haven't looked at Mongrel enough yet to know if it does body parsing or just headers.

May not be as fast...

I wrote a quick XS wrapper for benchmark purposes and for parsing a real-world header, here are the results.

                  Rate http-parser-xs        perlbal
http-parser-xs 55582/s             --           -12%
perlbal        63509/s            14%             --

This is just raw parsing speed, not creation of a useful HTTP::Request object.
