From 6626833db13a69786f9f6cd56b9f53c4017c3e39 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jos=C3=A9=20Valim?= Date: Sat, 8 May 2010 17:44:40 +0300 Subject: Revert "Add index length support for MySQL [#1852 state:open]" This commit breaks dumping a few tables, as the sessions table. To reproduce, just create a new application and: rake db:sessions:create rake db:migrate rake db:test:prepare And then look at the db/schema.rb file (ht: Sam Ruby).
