• Sqitch Update: The Plan

  https://justatheory.com/2012/05/sqitch-plan

  I gave my first presentation on Sqitch at PGCon last week. The slides are on Slideshare and the PGCon site. It came together at the last minute, naturally. I was not able to pay as close attention to PGCon sessions as I would have liked, as I was doing last minute hacking to get the deploy command working on PostgreSQL, and then writing the slides (which are based on the tutorial). I was pleased with the response, given that this is very much a project that is still under heavy development and available only as a very very early alpha. There was great discussion and feedback afterward, which I appreciate.

  Database migration frameworks and ad-hoc solutions leave things…wanting. Herein lie some preliminary thoughts on how to solve this problem.

  Last month I gave two presentations at the PostgreSQL Conference West. The first was a variation on Unit Test Your Database!, which I’ve now given about six times (and will at least two more times, including tomorrow night for Portland PLUG and in two weeks at the JPUG 10th Anniversary Conference). The second was a new talk, a 90-minute tutorial, called “pgTAP Best Practices.” And here it is (download and Slideshare). Enjoy!

• 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.
