Debugging Techniques for Drupal

A general approach to debugging Drupal problems will be presented, followed by an overview of a variety of tools such as the Devel suite, krumo, xdebug, and client side debugging such as Firebug and LiveHTTPHeaders. In addition to debugging functionality, approaches to performance related problems will be covered. Some of these techniques apply generally to all web applications or other PHP code.

A structured debugging approach that narrows down problems, rather than making random changes and guesses, is the main goal of the talk. Developers should come away with an approach to debugging as a specific activity separate from ordinary developement, that they can focus on and improve.

The audience will have a chance to share any debugging tricks they have during a question and answer session.
