Tim Starling implemented basic support for HipHop for PHP in MediaWiki, and invited other developers to improve and continue his work. We will pick this work back up later this year after the completion of some of the other projects above.

HipHop was discussed during the Berlin hackathon, and it was agreed that HipHop support would be part of the MediaWiki 1.20 release.

HipHop support is still planned to be part of MediaWiki 1.20. In the meantime, we're looking for volunteers to help us package it for different distributions. Please contact Sumana Harihareswara or the wikitech-l mailing list if you have experience with packaging or would like to get involved in this area.

Mark Hershberger and Tim Starling, with volunteer Mike Dupont, are seeking help with Debian packaging for HipHop.

Facebook has announced that it will be providing virtual machines for HipHop. That will aid in developing for it. The Roadmap now calls for Platform Engineering and Ops to make more decisions and plans regarding HipHop in February 2012.

After Facebook announced that they were developing virtual machines for HipHop, Tim Starling indicated that Wikimedia would put their current efforts on HipHop on hold, until the virtual machines can be evaluated. Other performance efforts like Wikitext scripting will take priority instead.

Several engineers at the Wikimedia Foundation met with Facebook engineers to discuss potential deployment of HHVM in 2013 (summary). We formed the HipHop mailing list to discuss moving forward with this work.

Work is starting back up on this, with the goal of having at least one production service running on HipHop by the end of the quarter. Tim Starling is working with the HHVM upstream to finish off a compatibility layer for running Zend extensions (ext_zend_compat) under HipHop, with the goal of using it for our Lua module. Ori Livneh is working on packaging and deployment issues, as well as generally wrangling the overall development effort. Aaron Schulz is starting to investigate what is needed for wmferrors support.

The team continued to work on porting C extensions to HHVM. Tim Starling did major work on a compatibility layer allowing Zend extensions to be used by HHVM, and started further work on making the layer compatible with newer HHVM interfaces. The team has made a preliminary deployment of HHVM to the Beta cluster, but this still needs further debugging before it is useful to a wider audience.
