• Sqitch — VCS-powered SQL Change Management

  https://justatheory.com/2012/04/sqitch-draft

  Back in January, I wrote three posts outlining some ideas I had about a straight-forward, sane way of managing SQL change management. The idea revolved around specifying scripts to deploy and revert in a plan file, and generating that plan file from VCS history. I still feel pretty good about the ideas there, and work has agreed to let me write it and open-source it. Here is the first step making it happen. I call it “Sqitch.”

• Keep DBI's connect_cached From Horking Transactions

  https://justatheory.com/2009/09/dbi-connect-cached-hack

  I’ve been on a bit of a Perl hacking tear lately. In addition to knocking out Test::XPath last week, I’ve been experimenting with TAP::Harness sources, Template::Declare, Catalyst views, a new Module::Build subclass for building database-backed applications, and, last but not least, an IRC logging bot. Oh, and that application I’m working on for PGX with Quinn Weaver. So much is crowding my mind these days that I’m having trouble sleeping. Tonight I’m up late hacking to try to get some of this stuff out of my head.

• Sqitch: Rename Step Objects and the SQL Directory?

  https://justatheory.com/2012/06/sqitch-steps-to-change

  After all of the thinking and rethinking about how to manage a Sqitch plan, I am just about done with all the changes to make it all work. One of the changes I’ve made is that tags are no longer objects that stand on their own between change steps, but are simply names the refer to specific change steps. Not only is this much more like how a VCS thinks of tags (basically another name for a single commit), but it also greatly simplifies the code for iterating over a plan and updating metadata in the database.
