| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `merged_options` method is private and the output is never mutated. Using this info we can get rid of the `dup` behavior. We can also eliminate the `merge` call in the case where all the options being merged are the same. Returned results are frozen as an extra layer of protection against mutation. Before ``` Total allocated: 741749 bytes (6642 objects) ``` After ``` Total allocated: 734039 bytes (6648 objects) ``` Diff ``` (741749 - 734039) / 741749.0 => ~ 1.0 % ``` If you don't feel comfortable modifying this method, we could rename it and only use it internally.

* Don't marshal ActiveSupport::Cache::Entry objects twiceSean Griffin2018-03-141-13/+14
| | | | | | | | | When upgrading to Rails 5.2 we're seeing `ActiveSupport::Cache::Entry#compress` and `ActiveSupport::Cache::Entry#should_compress?` as the highest usage of our CPU. At least some part of this is coming from the fact that objects are being marshaled multiple times. This memoizes the marshaled value to eliminate half the problem.

* Cache: Enable compression by default for values > 1kB.Jeremy Daer2017-11-131-11/+9
| | | | | | | | | | | | | Compression has long been available, but opt-in and at a 16kB threshold. It wasn't enabled by default due to CPU cost. Today it's cheap and typical cache data is eminently compressible, such as HTML or JSON fragments. Compression dramatically reduces Memcached/Redis mem usage, which means the same cache servers can store more data, which means higher hit rates. To disable compression, pass `compress: false` to the initializer.
* Built-in Redis cache storeJeremy Daer2017-11-131-12/+33
| | | | | | | | | | | * Supports vanilla Redis, hiredis, and Redis::Distributed. * Supports Memcached-like sharding across Redises with Redis::Distributed. * Fault tolerant. If the Redis server is unavailable, no exceptions are raised. Cache fetches are treated as misses and writes are dropped. * Local cache. Hot in-memory primary cache within block/middleware scope. * `read_/write_multi` support for Redis mget/mset. Use Redis::Distributed 4.0.1+ for distributed mget support. * `delete_matched` support for Redis KEYS globs.

| | | | | | | | | | | Rails.cache.write_multi foo: 'bar', baz: 'qux' Plus faster `fetch_multi` with stores that implement `write_multi_entries`. Keys that aren't found may be written to the cache store in one shot instead of separate writes. The default implementation simply calls `write_entry` for each entry. Stores may override if they're capable of one-shot bulk writes, like Redis `MSET`.

| | | | | | | | | | | | | tjschuck/require_as_notifications_in_cache" This reverts commit b86631d9d9f12d834868ff44735ff551668bfb8a, reversing changes made to 8776a7139757d0b264785c774d4e7f37d4bc1ac7. ActiveSupport::Notifications is loaded using autoload that is defined by the top level file of `active_support`. All the frameworks of Rails requires the top level files before using any of the others files inside the framework because the top level file is what setup the autoload hooks and require the common dependencies.
* Explicitly require AS::Notifications in AS::CacheT.J. Schuck2017-04-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now, if you install the current release version of Active Support (5.0.2) and try to use its cache implementation standalone by requiring `active_support/cache`, it crashes with `NameError: uninitialized constant ActiveSupport::Notifications`. `AS::Notifications` is used in `cache.rb` down around [line 555](https://github.com/rails/rails/blob/8776a7139757d0b264785c774d4e7f37d4bc1ac7/activesupport/lib/active_support/cache.rb#L555). Here's a quick repro script: ```ruby require "bundler/inline" gemfile(true) do source "https://rubygems.org" gem "activesupport", "5.0.2" end require "active_support/cache" cache_store = ActiveSupport::Cache::MemoryStore.new cache_store.write('test', 'okay') puts cache_store.read('test') ``` However, any version _newer_ than 5.0.2 passes. This is because [this commit](https://github.com/rails/rails/commit/75924c4517c8f87712d3f59c11f10152ed57b9d8) inadvertently included `AS::Notifications` into `AS::Cache` (thus fixing the issue) by mixing [`AS::Deprecation` into `AS::Duration`](https://github.com/rails/rails/blob/75924c4517c8f87712d3f59c11f10152ed57b9d8/activesupport/lib/active_support/duration.rb#L4), giving you a nice require chain of [`Cache` including `Time`][1] [including `Duration`][2] [including `Deprecation`][3] [including `Behaviors`][4] [including `Notifications`][5]. Phew. Aside from being not very explicit, the fact that the fixing is specifically done by `AS::Deprecation` means that this fix is probably only temporary (until the deprecation is removed). This PR just makes the inclusion explicit to future-proof against this breakage. (Ideally, this would also be backported to `5-0-stable` to get picked up in any subsequent point release.)
