documentation branch

rails core

rails.lighthouseapp.com

Rails 2.1

app extractions

from real world apps, timezones, named scopes

refactoring / doc / thiner + faster

making rails beauty, speed, rubyprof, http://ruby-prof.rubyforge.org/, smaller footprint

features

merging migrations, timestamps, tracking already applied migrations, cursor => schema_version, history => schema_migrations

time_zone situps, mesage.created_at.to_s(:short), Time.zone = current_user.time_zone, Time.zone.now, Time.zone.parse '5/30/08', etc..., ActiveSupport::TimeWithZone, config.time_zone = 'Tijuana'

gem dependencies, config.gem 'mysql', :version => '2.7', rake -T gems

memcache, memcache-client blunded, config.cache_store = :mem_cache_store, %w(foo-app-01, foo-app-02), cache [user, :recent_messages], :expires_in => 1.minute

partial update / dirty, partial danger, optimistic locking!

smarter :include, avoids giant (unnecessary) join chains

named scopes
