* Revert "Fix expanding cache key for single element arrays"David Heinemeier Hansson2012-01-271-1/+1
| | | | | | This reverts commit abe915f23777efe10f17d611bf5718ca855a0704. This broke all existing keys and it's wrong anyway. The array is just there as a convenience option for building the string. It's intentional that [ "stuff"] and "stuff" generates the same key.

| * Fix expanding cache key for single element arraysOlek Janiszewski2011-12-161-1/+1
| | | | | | | | | | | | | | | | | | In short: expand_cache_key(element) should not equal expand_cache_key([element]) This way a fragment cache key for an index page with only a single element in the collection is different than a fragment cache for a typical show page for that element.

* ActiveSupport::Cache refactoringBrian Durand2010-04-271-69/+427
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All Caches * Add default options to initializer that will be sent to all read, write, fetch, exist?, increment, and decrement * Add support for the :expires_in option to fetch and write for all caches. Cache entries are stored with the create timestamp and a ttl so that expiration can be handled independently of the implementation. * Add support for a :namespace option. This can be used to set a global prefix for cache entries. * Deprecate expand_cache_key on ActiveSupport::Cache and move it to ActionController::Caching and ActionDispatch::Http::Cache since the logic in the method used some Rails specific environment variables and was only used by ActionPack classes. Not very DRY but there didn't seem to be a good shared spot and ActiveSupport really shouldn't be Rails specific. * Add support for :race_condition_ttl to fetch. This setting can prevent race conditions on fetch calls where several processes try to regenerate a recently expired entry at once. * Add support for :compress option to fetch and write which will compress any data over a configurable threshold. * Nil values can now be stored in the cache and are distinct from cache misses for fetch. * Easier API to create new implementations. Just need to implement the methods read_entry, write_entry, and delete_entry instead of overwriting existing methods. * Since all cache implementations support storing objects, update the docs to state that ActiveCache::Cache::Store implementations should store objects. Keys, however, must be strings since some implementations require that. * Increase test coverage. * Document methods which are provided as convenience but which may not be universally available. MemoryStore * MemoryStore can now safely be used as the cache for single server sites. * Make thread safe so that the default cache implementation used by Rails is thread safe. The overhead is minimal and it is still the fastest store available. * Provide :size initialization option indicating the maximum size of the cache in memory (defaults to 32Mb). * Add prune logic that removes the least recently used cache entries to keep the cache size from exceeding the max. * Deprecated SynchronizedMemoryStore since it isn't needed anymore. FileStore * Escape key values so they will work as file names on all file systems, be consistent, and case sensitive * Use a hash algorithm to segment the cache into sub directories so that a large cache doesn't exceed file system limits. * FileStore can be slow so implement the LocalCache strategy to cache reads for the duration of a request. * Add cleanup method to keep the disk from filling up with expired entries. * Fix increment and decrement to use file system locks so they are consistent between processes. MemCacheStore * Support all keys. Previously keys with spaces in them would fail * Deprecate CompressedMemCacheStore since it isn't needed anymore (use :compress => true) [#4452 state:committed] Signed-off-by: Jeremy Kemper <jeremy@bitsweat.net>
