Objectifying Drupal: What do you want to know?

So we're a month away from DrupalCon DC 2009, and although the official schedule has not been published it seems likely from the preliminary schedule that my Objectifying Drupal session will be accepted. The basic idea is to help Drupal's mainly procedural army of developers get up to speed on object-oriented development, which has been gaining popularity in contrib (most notably the Views module) and will be in many parts of Drupal 7.

Of course, given how large an army of developers we have there is no one level of existing expertise I can target. There are entire multi-course college programs on OOP design, and I have an hour. :-) So, how about some preliminary feedback? What do you want to see in a one hour session on object-oriented code in Drupal?

Dependency injection, testing, and Drupal

Via Planet PHP I stumbled across this article decrying Singletons. It's not a new argument, really, but one of the comments pointed me toward a Google Tech Talk video entitled "Global State and Singletons". To be honest I don't agree with everything said in either the article or the video, but both are spot on about the problems of global state, something I've lamented before in relation to testing.

That is especially relevant now, as we consider the question of Handlers in Drupal. Why? Because the most controvercial part so far, the environment variable, is designed to address exactly this problem, a problem that is currently prevalent throughout all of Drupal.

Permit me to explain.

Handlers in core: Concept Needs Review

Some time ago, I posted an RFC for pluggable "system handlers". It generated a fair bit of feedback, nearly all of it positive. That was followed up with a presentation in Szeged, which generated even more positive feedback.

So what's happened since then? Well, a fair bit. There's working code, but there are still some key gotchas to sort out. That gives us a couple of options for how to proceed, for which I would like feedback, particularly from core developers and maintainers. (Dries, webchick, this means you! :-) )

Autoloading classes in Drupal 6

I need to not have spare time. When I have spare time, I do crazy things. Not crazy things like your mother told you not to do, but things like write modules on a lark.

Like I said, dangerous. But, useful. In this case, it was a conversation over on Ryan Szrama's blog that kinda got out of hand and gave me another idea for a module, which I am happy to announce is now available for download.
