On many of our projects we use Gearman to do background processing. One of problems with doing things in the background is that the web debug toolbar isn’t available to help with debugging problems, including queries. Normally when you want to see your queries you can look at the debug toolbar and get a runnable version of the query quickly. However, when its running in the background, you have to look at the application logs to see what the query is. The logs don’t contain a runnable format of the query, for example they may look like this:
Problem is you can’t quickly take that to your database and run it to see the results. Plugging in the parameters is easy enough, but it takes time. I decided to quickly whip up a script that will take what is in the gist above and convert it to a runnable format. I’ve posted this over at http://code.setfive.com/doctrine-query-log-converter/ . This hopefully will save you some time when you are trying to debug your background processes.
It should work with both Doctrine 1.x/symfony 1.x and Doctrine2.x/Symfony2.x. If you find any issues with it let me know.
Good luck debugging!
