Rails::Configuration default_cache_store not called

+1

I recently run into this issue, because Rails 2.1 kept storing my cache in memory, instead of tmp/cache and I had to debug extensively.

(I wanted to preserve cache content between deploys on a particular ActiveResource-based application. No need to flush precious cached content because of some minor change in CSS, better done with precision aim of Cap/Rake task).

Looks like this was added.

    def initialize_cache
      unless defined?(RAILS_CACHE)
        silence_warnings { Object.const_set "RAILS_CACHE", ActiveSupport::Cache.lookup_store(configuration.cache_store) }
      end
    end
