Facebook: HipHop for PHP

Facebook officially announced the project, titled HipHop, this morning and confirmed that it would be released as open source this evening.

Facebook has been working on a PHP compiler that will increase speed by around 80% and offer a just-in-time (JIT) compilation engine that will offer a number of advantages.

Less CPU means fewer servers, which means less overhead. This project has had a tremendous impact on Facebook

HipHop for PHP isn’t technically a compiler itself, it is a source code transformer. HipHop programmatically transforms your PHP source code into highly optimized C++ and then uses g++ to compile it.

HipHop executes the source code in a semantically equivalent manner and sacrifices some rarely used features — such as eval() — in exchange for improved performance.

HipHop includes a code transformer, a reimplementation of PHP’s runtime system, and a rewrite of many common PHP Extensions to take advantage of these performance optimizations.

Simple registration request and response parsing and object representation

This module contains objects representing simple registration requests and responses that can be used with both OpenID relying parties and OpenID providers.

  1. The relying party creates a request object and adds it to the AuthRequest object before making the checkid_ request to the OpenID provider: 
    auth_request.addExtension(SRegRequest(required=['email']))
  2. The OpenID provider extracts the simple registration request from the OpenID request using SRegRequest.fromOpenIDRequest, gets the user’s approval and data, creates a SRegResponse object and adds it to the id_res response: 
    sreg_req = SRegRequest.fromOpenIDRequest(checkid_request.message)
# [ get the user's approval and data, informing the user that
#   the fields in sreg_response were requested ]
sreg_resp = SRegResponse.extractResponse(sreg_req, user_data)
sreg_resp.toMessage(openid_response.fields)
  3. The relying party uses SRegResponse.fromSuccessResponse to extract the data from the OpenID response: 
    sreg_resp = SRegResponse.fromSuccessResponse(success_response)
