Add read_multi to ActiveSupport::Cache::Store

Reported by matthuhiggins | September 11th, 2009 @ 08:55 AM

I currently run unit tests with MemoryStore, and production with MemCacheStore. I use the 'read_multi' method provided by MemCacheStore, but read_multi is only available to MemCacheStore, so the code breaks in tests.

I realize that I can fix my tests by always using :memcache_store, and wrapping every test using 'with_local_cache' (defined in ActiveSupport::Cache::Strategy::LocalCache). However, this method is not documented, and I'm not sure if developers should be using this. If I'm testing incorrectly, this ticket is awash.

This patch adds 'read_multi' to the Rails.cache API. It duplicates the memcache behavior in that the arguments are flattened, and nonexistent keys are not included in the results.
