* Fix elapsed time calculationsbogdanvlviv2019-02-081-2/+2
| | | | | | | | | | | | | | | | | | | I've found a few places in Rails code base where I think it makes sense to calculate elapsed time more precisely by using `Concurrent.monotonic_time`: - Fix calculation of elapsed time in `ActiveSupport::Cache::MemoryStore#prune` - Fix calculation of elapsed time in `ActiveRecord::ConnectionAdapters::ConnectionPool::Queue#wait_poll` - Fix calculation of elapsed time in `ActiveRecord::ConnectionAdapters::ConnectionPool#attempt_to_checkout_all_existing_connections` - Fix calculation of elapsed time in `ActiveRecord::ConnectionAdapters::Mysql2Adapter#explain` See https://docs.ruby-lang.org/en/2.5.0/Process.html#method-c-clock_gettime https://blog.dnsimple.com/2018/03/elapsed-time-with-ruby-the-right-way Related to 7c4542146f0dde962205e5a90839349631ae60fb

* [close #33907] Error when using "recyclable" cache keys with a store that ↵schneems2018-09-201-0/+7
| | | | | | | | | | | | | | does not support it If you are using the "in cache versioning" also known as "recyclable cache keys" the cache store must be aware of this scheme, otherwise you will generate cache entries that never invalidate. This PR adds a check to the initialization process to ensure that if recyclable cache keys are being used via ``` config.active_record.cache_versioning = true ``` Then the cache store needs to show that it supports this versioning scheme. Cache stores can let Rails know that they support this scheme by adding a method `supports_in_cache_versioning?` and returning true.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ActiveSupport::Cache::MemoryStore Previously, the cache size of `ActiveSupport::Cache::MemoryStore` was calculated as the sum of the size of its entries, ignoring the size of keys and any data structure overhead. This could lead to the calculated cache size sometimes being 10-100x smaller than the memory used, e.g., in the case of small values. The size of a key/entry pair is now calculated via `#cached_size`: def cached_size(key, entry) key.to_s.bytesize + entry.size + PER_ENTRY_OVERHEAD end The value of `PER_ENTRY_OVERHEAD` is 240 bytes based on an [empirical estimation](https://gist.github.com/ssimeonov/6047200) for 64-bit MRI on 1.9.3 and 2.0. Fixes GH#11512 https://github.com/rails/rails/issues/11512

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
