I cannot say I really need features from 2.3, but I think it worth using the latest release (especially given that I already had to patch my Rails 2.2.2 installation to remove some bugs from it).
As usual, the migration turns to be an adventure:
- Change all tests which extend
Test::Unit::TestCaseand use fixtures with
- Many test failures were fixed by adding
self.use_transactional_fixtures = falseto
- Fixed tests with cookies (see a good post with the explanation)
- Faced a bug with cookie escaping in tests. This bug is not fixed in 2.3.2, so some tests are failing unless edge 2.3.x is used.
- DEPRECATION: formatted_ paths had to be replaced. Replaced.
- DEPRECATION: session.delete => session.clear
- DEPRECATION: session.session_id => request.session_options[:id] (faced another already fixed bug)
Some of these issues are described in Rails 2.3 change log. And some (like bugs ;) are not.
So now, tests are successful again (for the latest 2.3 branch). But I'm not going to update production yet, will do some more testing. And, probably, wait for 2.3.3.
