We're working on migrating Zend Framework to Git. One issue we're trying to deal with is enforcing that commits come from CLA signees.

One possibility presented to us was the possibility of utilizing GPG signing of commit messages. Unfortunately, I was able to find little to no information on the 'net about how this might be done, so I started to experiment with some solutions.

The approach I chose utilizes git hooks, specifically the commit-msg hook client-side, and the pre-receive hook server-side.

Brandon Savage approached me with an interesting issue regarding ZF bootstrap resources, and accessing them in your action controllers. Basically, he'd like to see any resource initialized by the bootstrap immediately available as simply a public member of his action controller.

So, for instance, if you were using the "DB" resource in your application, your controller could access it via $this->db.

I see a number of questions regularly about module bootstraps in Zend Framework, and decided it was time to write a post about them finally.

In Zend Framework 1.8.0, we added Zend_Application, which is intended to (a) formalize the bootstrapping process, and (b) make it re-usable. One aspect of it was to allow bootstrapping of individual application modules -- which are discrete collections of controllers, views, and models.

The most common question I get regarding module bootstraps is:

Why are all module bootstraps run on every request, and not just the one for the requested module?

To answer that question, first I need to provide some background.

In previous articles, I've explored building service endpoints and RESTful services with Zend Framework. With RPC-style services, you get to cheat: the protocol dictates the content type (XML-RPC uses XML, JSON-RPC uses JSON, SOAP uses XML, etc.). With REST, however, you have to make choices: what serialization format will you support?

Why not support multiple formats?

There's no reason you can't re-use your RESTful web service to support multiple formats. Zend Framework and PHP have plenty of tools to assist you in responding to different format requests, so don't limit yourself. With a small amount of work, you can make your controllers format agnostic, and ensure that you respond appropriately to different requests.
