While I’m a big fan of dependency injection, I find dependency injection containers less alluring. I’ve found that liberal usage of containers can make application code harder to follow, and often the container definitions go untested, creating a spawning pool for bugs.
I’m always looking for new challenges. With my background mostly being in web development, I have little to no experience in low-level languages. In the past I’ve tinkered with C, and go-lang. This summer, I decided to try and learn Rust. Rust aims to be a very safe and performant systems-level language.
For a number of years, I’ve developed the AssetCompress CakePHP plugin. Simultaneously, I’ve maintained similar code at FreshBooks.
With CakePHP 3.0 out the door, I thought it would be good to reflect on the project. CakePHP 3.0 is the longest and largest open source project milestone I’ve ever participated in. At FreshBooks we do retrospectives on large projects as a way to see what went well, and what could have gone better. The goal is to discover things we should keep doing, and what to improve the next time around.
One approach to scaling out a database for a multi-tenant application is to horizontally shard or partition the data by customer. This often takes the form of having multiple identical copies of an application’s schema in each shard. For example customer A’s data would be in shard 1, while customer C’s data would be in shard 2.
I recently finished upgrading this site to CakePHP 3.0.0-dev from 2.5.5. I thought I’d share my experiences, as they might be helpful to other people attempting to update a CakePHP 2.x application to 3.0.
In terms of scale & size, this site is pretty small and simple. It has a mere 12 tables, and ~5000 lines of code including HTML, and uses 3 plugins.
Earlier today, I packaged up AssetCompress 0.17. This release has a few noteworthy features.
Cached builds in development
Historically, in development every build file would be rebuilt on every request even if the source files did not change. While this works OK if you have a few build targets, it can get pretty slow if you have many build targets, big build targets or use a pre-processor like sass. As of 0.
A few weeks back during CakeFest 2014, I had the opportunity to hunker down and get DebugKit upgraded to CakePHP 3.0. While it was less of an upgrade and more of a re-design and re-write, I think the end results justify the drastic approach I took. First, a few of the problems I was trying to solve in the new version:
1. It is hard to make DebugKit look great as it lives on the same page as your app.
