This refactors the RequestHandler code, to decouple RequestHandler behavior from the Server implementation. The goal is to make it easier to define additional Server implementations, in addition to just LibEventServer. This adds a RequestHandlerFactory function, rather than using a pure virtual method of the Server class. With the old model, you had to subclass each server implementation separately for each RequestHandler type you wanted to use, resulting in NxM classes if you have N server types and M request handler types. This also changes the behavior of the RequestHandler class somewhat: the code now only creates a single RequestHandler per thread, and uses that object for all request in that thread. Previously the LibEventServer code would attempt to create a new RequestHandler object for each request if supportReset() returned true. This was used by RPCRequestHandler. Now the RPCRequestHandler instead just resets itself automatically when necessary, without requiring external help from LibEventServer. contbuild test runs failed due to git server issues.
HipHop VM for PHP 
HipHop VM (HHVM) is a new open-source virtual machine designed for executing programs written in PHP. HHVM uses a just-in-time compilation approach to achieve superior performance while maintaining the flexibility that PHP developers are accustomed to. HipHop VM (and before it HPHPc) has realized > 5x increase in throughput for Facebook compared with Zend PHP 5.2.
HipHop is most commonly run as a standalone server, replacing both Apache and modphp.
Installing
You can install a prebuilt package or compile from source.
Running
You can run standalone programs just by passing them to hhvm: hhvm my_script.php.
HipHop bundles in a webserver. So if you want to run on port 80 in the current directory:
sudo hhvm -m server
For anything more complicated, you'll want to make a config.hdf and run sudo hhvm -m server -c config.hdf.
Contributing
We'd love to have your help in making HipHop better. If you run into problems, please open an issue, or better yet, fork us and send a pull request. Join us on #hhvm on freenode.
If you want to help but don't know where to start, try fixing some of the Zend tests that don't pass. You can run them with hphp/test/run. When they work, move them to zend/good and send a pull request.
