File cache store is limited by filename length constraint.

File cache store is limited by filename length constraint.

This seems more of an issue with the underlying cache store, per rails/rails#10894, but I'm taking a look into a reasonable fix within Garner.

[fancyremarker]

So, rails/rails#4907 is actually the more relevant issue, and rails/rails#4911 fixes this. In lieu of upgrading to Rails 4.0, I recommend something like the following in an initializer:

silence_warnings do
  ActiveSupport::Cache::FileStore::FILENAME_MAX_SIZE = 228
end

Cool! Thanks!!

Setting the max size didn't work. One workaround is to use a MemoryStore. Another is a possible monkey patch:

module Garner
  module Cache

    private

    class << self

      alias_method :_compound_key, :compound_key

      def compound_key(bindings, key_hash)
        key = _compound_key(bindings, key_hash)
        Digest::SHA1.hexdigest(key.to_s) if key
      end

    end

  end
end

File paths of unlimited length seem problematic even if we're able to work around this particular obstacle. Are there any drawbacks to using the digest instead?
