Database setup on CircleCI gives RAILS_CACHE error

[meltingice]

This always happens when trying to setup the database on CircleCI. I cannot seem to produce this locally in Mac OSX. File ordering can be different on Linux, which can cause bugs like this, but I'm having a hard time pinning down where RAILS_CACHE is originally defined.

Running:

• Ruby 2.0.0
• Rails 3.2.16
• makara 0.2.0 ab0b485

ubuntu@box15:~/layervault$ RAILS_ENV=test bundle exec rake db:create db:schema:load --trace
** Invoke db:create (first_time)
** Invoke db:load_config (first_time)
** Execute db:load_config
** Invoke rails_env (first_time)
** Execute rails_env

If I override the database creation such that it loads the full Rails environment first, it works.

bundle exec rake environment db:create db:schema:load --trace

Not sure if this is really the best solution, though.

So a possible option for makara is to check for the existence of RAILS_CACHE before trying to use Rails.cache. RAILS_CACHE is deprecated, however, so we'd have to do that with an AR version check.

An alternative to loading the env is to set the makara cache explicitly: Makara::Cache.store = :noop.
