Leon Brocard (aka acme) is an orange-loving Perl eurohacker with many varied contributions to the Perl community, including the GraphViz module on the CPAN. YAPC::Europe was all his fault. He is still looking for a Perl Monger group he can start which begins with the letter 'D'.

HTTP Parser

[ #35298 ]
Dear Lazyweb, please write a XS module which interfaces to Mongrel's HTTP Parser (also seen in Thin). I'll buy you dimsum!

  • 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.
  • 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, n
