Collapsing Migrations
(6:30 pm: updated to use mysqldump) (12/14/07: updated to remove db:reset since the Rails 2.0 version now does something different.) (12/15/07: updated to not set ENV['RAILS_ENV'] since that gets passed down to child processes)
There was an old hacker who lived in a shoe; she had so many migrations she didn't know what to do. Every time her build ran clean, she spent a whole minute staring at the screen.
Fortunately, she read this blog post and now her db:setup task is so fast she's started building multiple test environments so she can run tests in parallel!
