Plugin Compatibility Checker for CakePHP by Damien Damien Seguy

While PHP compatibility is a classic quest, CakePHP compatibility is an uncharted new territory. With each version of the platform, new classes, methods and arguments appears, while other fade away: this is the pace of modern evolution. And it is a lot easier to keep up with an automated tool.
We introduce the PDFF archive. PHP Document File Format is an open source format, built from the very source of CakePHP. It provides an encyclopedic description of the OOP API. Static analysis tool take full advantage of this knowledge to audit the code and identify discrepancies, both at PHP and CakePHP level.
Best of all, PDFF is both machine and human friendly : it serves as documentation, by listing all structural evolutions, and help cross the versions gap : including the upcoming ones.
During this presentation, we’ll describe what are PDFF files, how they are used with static analysis and automated documentation, and what other usage are planned for the future.
