Facebook’s Hiphop

I spent several hours Saturday poking around in Facebook’s new Hiphop PHP source code compiler. I haven’t successfully built the program yet, but after taking some time to review the source code I’m very optimistic.

I would have a build already, but I tried to build the tool on a virtual server with 256Megs of ram. The only problem is that one of the source code files is 1.8 MB of text. The compiler footprint would balloon up to 800 Megs and swap thrash for a while before ultimately running out of memory when it tried to compile it. I’m going to build a 2Gig VM soon and that should be plenty of RAM to get it to build successfully.
