Version 0.7 of The State Decoded is now available on GitHub. This is a really meaty release, dedicated entirely to optimizations: it’s faster, more efficient, easier to extend, easier to contribute to, easier to deploy, and easier to navigate. This release is comprised of a whopping 353 Git commits—that’s more than every commit that went into versions 0.1 through 0.6, combined. Here are some of the major changes:
Tuning
Every line of code was reviewed to see how it could be made faster—in tiny ways (instances of stristr() replaced with strstr()—or, better, strpos()) and in large ways (tossing out whole methods and starting again). The indices in MySQL were evaluated and revised, and any PHP error of level E_NOTICE and above was quieted. And the parser’s memory usage has been reduced substantially, making it faster and more efficient to process large legal codes that previously might have strained (or broken) Apache’s per-process memory limit.
Caching
There are now hooks for both APC and Varnish, so that folks running either of those popular caching applications (or, better, both of them) can reap the speed benefits. API keys, all constants, and templates are cached in APC now, with more caching on tap in upcoming releases.
Development Environment
This version was developed substantially within a Vagrant staging environment, resulting in the inevitable optimization of The State Decoded to run within Vagrant. That involved a lot of tiny changes (e.g., respecting port numbers in URLs) that collectively create a smooth experience when developing locally. We have the under-development Vagrant configuration for The State Decoded in its own repository. This version and all future versions will have a Vagrant machine image available for download, to make it trivial to get started. Vagrant is working on a path to deploy Vagrant machine configurations as AWS instances, which is why this is a bandwagon worth hopping on now.
Standardization
Out with HTML Purifier, in with HTML Tidy. Out with MDB2, in with PDO. Out with late-nineties-style commenting and code formatting, in with PEAR-style commenting and code formatting. There was nothing wrong with any of those prior approaches, but it’s best to establish an environment that contributors expect—that makes it easier for folks to contribute code to the project, or customize it for their own website. Also, HTML Tidy and PDO are already installed by default on a great many systems, which simplifies the setup process.
Extensibility
Several steps have been made to facilitate customization. All non-obvious database columns are now commented, there’s infrastructure for inline help text (stored and distributed as JSON), and there’s support for importing, storing, and display arbitrary metadata fields alongside the standard data about each law.
New Features
And, of course, we couldn’t resist a few new features. There’s now keyboard navigation within laws and structures, for those power-users who want to flip through laws quickly. There’s baked-in support for Disqus-based commenting on each law page—just enter your site’s Disqus shortname in config.inc.php and you’re up and running. And, finally, there’s bulk generation of both plain text and JSON versions of laws. To what end? Dunno—that’s for you to figure out.
This release involved a lot of work over the course of four months. Bill Hunt has scrubbed in to help as a core contributor, and he’s responsible for a lot of these improvements. Some very helpful bug reports, wiki edits, and pull requests came from Chris Birk and Daniel Trebbien.
Next up: versions 0.8 and 0.9, which will be released soon, and close together. Version 0.8 will be comprised of the UI/UX branch, which only has a handful of small tasks remaining, thanks to months of work by Meticulous (John Athayde and Lynn Wallenstein). And Version 0.9 will be comprised of the Solr branch, and is dedicated to baking Apache Solr into The State Decoded. That’s based on several months of work by the team at OpenSource Connections, who finished up earlier this week—there are only about a dozen outstanding issues, all of which build on OSC’s work to add some valuable new features to The State Decoded.
