TODO Should the cache be cleared if new translations are stored?
In Ruby < 1.9 the following is true: { :foo => 1, :bar => 2 }.hash == { :foo => 2, :bar => 1 }.hash Therefore we must use the hash of the inspect string instead to avoid cache key colisions.
# File lib/i18n/backend/cache.rb, line 78 78: def _fetch(cache_key, &block) 79: result = I18n.cache_store.read(cache_key) and return result 80: result = catch(:exception, &block) 81: I18n.cache_store.write(cache_key, result) unless result.is_a?(Proc) 82: result 83: end
