MemcacheStore: deserialize the entry reading from local_cache when using

MemcacheStore: deserialize the entry reading from local_cache when using raw.

When with :raw => true and storing the Marshal.dump(obj) into the memcached, Rails.cache.read(key) will return the the serialization data. MemCacheStore should try to deserialize the entry before returning the result.

I like this idea. How do you think @josevalim?

[josevalim]

But isn't :raw exactly about storing a raw object (without dumping)? If your code is dumping it before caching it, you are expected to Marshal.load it as well.

[josevalim]

In other words, what is your use case? :)

The problem is not that leave Marshal.load to app when fetching, instead, the solution here is not consistent.

When the entry doesn't exist in LocalCache, the MemcacheStore will try to Marshal.load the raw value before returning the value to app. However, if the entry exists in LocalCache, it will directly return the raw value without Marshal.load.

So we should always leave the dump/load to app users or deserialize both.

Ah, now I see. The original issue was not clear in the issue message. Thanks.
