  • State changed from “new” to “invalid”

  The MemoryStore has been killed off. I'd recommend either using active_record_store or, even better, start using the default cookie store.

  Hi all, I can not see a reason to remove memory_store from rails 2.3 sessions. Sometimes it is too much simple to configure a session as : config.action_controller.session_store = :memory_store

  I do not feel comfortable in use active_record_store or mem_cache_store in my app. My application does not have a database, so I am not using the active_record_store, and I do not want to configure one because all my data comes from Semantic Web endpoints.

  Also, I don't want to configure a cache server to store users' sessions because my app is too small to demand such effort.

  I thing that :memory_store has its applicability and should be kept in future version.

  :memory_store is useful only in very limited circumstances -- very simple servers where session data must be kept secret, or servers which require session fixation for other reasons. But here is a re-implementation for Rails 2.3, in case you really need it. Put the file into It's not threadsafe, just like the original.

  # Port of old CGI::Session::MemoryStore to Rails 2.3
  module ActionController
    module Session
      # In-memory session storage class.
      #
      # Implements session storage as a global in-memory hash.  Session
      # data will only persist for as long as the ruby interpreter 
      # instance does.
      class MemoryStore < AbstractStore
        GLOBAL_HASH_TABLE = {} #:nodoc:
  
        private
          def get_session(env, sid)
            sid ||= generate_sid
            session = GLOBAL_HASH_TABLE[sid] || {}
            session = AbstractStore::SessionHash.new(self, env).merge(session)
            [sid, session]
          end
  
          def set_session(env, sid, session_data)
            GLOBAL_HASH_TABLE[sid] = session_data
            return true
          end
      end
    end
  end unless RAILS_GEM_VERSION =~ /^([01]\.|2\.[012]\.)/

  Create a file in config/initializers/ containing the above code; then your existing session configuration will continue to work in Rails 2.3.
