2018-03-08 18:04:39 -05:00
Added `config/credentials.yml.enc` file to store production app secrets.
It allows saving any authentication credentials for third-party services
directly in repository encrypted with a key in the `config/master.key` file or
the `RAILS_MASTER_KEY` environment variable.
This will eventually replace `Rails.application.secrets` and the encrypted
secrets introduced in Rails 5.1.
Furthermore, Rails 5.2
[opens API underlying Credentials](https://github.com/rails/rails/pull/30940),
so you can easily deal with other encrypted configurations, keys, and files.
[ci skip] Add securing rails app guide link to credential section * In 5.2 release note, added [securing rails app guide](http://edgeguides.rubyonrails.org/security.html#custom-credentials) link to [credentials section](http://edgeguides.rubyonrails.org/5_2_release_notes.html#credentials).

Rails 5.2 ships with a new DSL that allows you to configure a
[Content Security Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy)

values into the header such as account subdomains in a multi-tenant application.
Move CSP info from 5.2 release notes to guide [ci skip] - Add mention about "nonce". Related to https://github.com/rails/rails/pull/32222#issuecomment-372268157

rolledback. This will correctly mark records from the inner transaction
as not persisted.

post-type-cast value for rendering in single-field form inputs.

([Pull Request](https://github.com/rails/rails/pull/29916))
* `Relation#or` now accepts two relations who have different values for
`references` only, as `references` can be implicitly called by `where`.

`bin/rails db:migrate` with empty VERSION behaves as without `VERSION`.
Check a format of `VERSION`: Allow a migration version number
or name of a migration file. Raise error if format of `VERSION` is invalid.
Raise error if target migration doesn't exist.
([Pull Request](https://github.com/rails/rails/pull/30714))
* Add new error class `StatementTimeout` which will be raised
when statement timeout exceeded.
([Pull Request](https://github.com/rails/rails/pull/31129))
* `update_all` will now pass its values to `Type#cast` before passing them to
`Type#serialize`. This means that `update_all(foo: 'true')` will properly
persist a boolean.
([Commit](https://github.com/rails/rails/commit/68fe6b08ee72cc47263e0d2c9ff07f75c4b42761))

([Commit](https://github.com/rails/rails/commit/9e7260da1bdc0770cf4ac547120c85ab93ff3d48))
* Fixed inconsistency with `first(n)` when used with `limit()`.
The `first(n)` finder now respects the `limit()`, making it consistent
with `relation.to_a.first(n)`, and also with the behavior of `last(n)`.
([Pull Request](https://github.com/rails/rails/pull/27597))
* Fix nested `has_many :through` associations on unpersisted parent instances.
([Commit](https://github.com/rails/rails/commit/027f865fc8b262d9ba3ee51da3483e94a5489b66))

([Commit](https://github.com/rails/rails/commit/63fc1100ce054e3e11c04a547cdb9387cd79571a))
* Fix `#columns_for_distinct` of MySQL and PostgreSQL to make
`ActiveRecord::FinderMethods#limited_ids_for` use correct primary key values
even if `ORDER BY` columns include other table's primary key.
([Commit](https://github.com/rails/rails/commit/851618c15750979a75635530200665b543561a44))
* Fix `dependent: :destroy` issue for has_one/belongs_to relationship where
the parent class was getting deleted when the child was not.
([Commit](https://github.com/rails/rails/commit/b0fc04aa3af338d5a90608bf37248668d59fc881))

* Pass gem name and deprecation horizon to deprecation notifications.
([Pull Request](https://github.com/rails/rails/pull/28800))
* Add support for versioned cache entries. This enables the cache stores to
recycle cache keys, greatly saving on storage in cases with frequent churn.
Works together with the separation of `#cache_key` and `#cache_version`
in Active Record and its use in Action Pack's fragment caching.
([Pull Request](https://github.com/rails/rails/pull/29092))
* Add `ActiveSupport::CurrentAttributes` to provide a thread-isolated
attributes singleton. Primary use case is keeping all the per-request
attributes easily available to the whole system.

([Pull Request](https://github.com/rails/rails/pull/29681))
* Make the order of `Hash#reverse_merge!` consistent
with `HashWithIndifferentAccess`.
([Pull Request](https://github.com/rails/rails/pull/28077))
* Add purpose and expiry support to `ActiveSupport::MessageVerifier` and
`ActiveSupport::MessageEncryptor`.
([Pull Request](https://github.com/rails/rails/pull/29892))
* Update `String#camelize` to provide feedback when wrong option is passed.
([Pull Request](https://github.com/rails/rails/pull/30039))
* `Module#delegate_missing_to` now raises `DelegationError` if target is nil,
similar to `Module#delegate`.
([Pull Request](https://github.com/rails/rails/pull/30191))

`ActiveSupport::EncryptedConfiguration`.
([Pull Request](https://github.com/rails/rails/pull/30067))

`HashWithIndifferentAccess#transform_keys`.
([Pull Request](https://github.com/rails/rails/pull/30728))
* `Hash#slice` now falls back to Ruby 2.5+'s built-in definition if defined.
([Commit](https://github.com/rails/rails/commit/01ae39660243bc5f0a986e20f9c9bff312b1b5f8))
* `IO#to_json` now returns the `to_s` representation, rather than
attempting to convert to an array. This fixes a bug where `IO#to_json`
would raise an `IOError` when called on an unreadable object.
([Pull Request](https://github.com/rails/rails/pull/30953))
* Add same method signature for `Time#prev_day` and `Time#next_day`
in accordance with `Date#prev_day`, `Date#next_day`.
Allows pass argument for `Time#prev_day` and `Time#next_day`.
([Commit](https://github.com/rails/rails/commit/61ac2167eff741bffb44aec231f4ea13d004134e))

([Commit](https://github.com/rails/rails/commit/ee9d81837b5eba9d5ec869ae7601d7ffce763e3e))
* Fix acronym support in `humanize`.
([Commit](https://github.com/rails/rails/commit/0ddde0a8fca6a0ca3158e3329713959acd65605d))
* Allow `Range#include?` on TWZ ranges.

* Cache: Enable compression by default for values > 1kB.
([Pull Request](https://github.com/rails/rails/pull/31147))
* Redis cache store.
([Pull Request](https://github.com/rails/rails/pull/31134),
[Pull Request](https://github.com/rails/rails/pull/31866))
* Handle `TZInfo::AmbiguousTime` errors.
([Pull Request](https://github.com/rails/rails/pull/31128))
* MemCacheStore: Support expiring counters.
([Commit](https://github.com/rails/rails/commit/b22ee64b5b30c6d5039c292235e10b24b1057f6d))
* Make `ActiveSupport::TimeZone.all` return only time zones that are in
`ActiveSupport::TimeZone::MAPPING`.
([Pull Request](https://github.com/rails/rails/pull/31176))
* Changed default behaviour of `ActiveSupport::SecurityUtils.secure_compare`,
to make it not leak length information even for variable length string.
Renamed old `ActiveSupport::SecurityUtils.secure_compare` to
`fixed_length_secure_compare`, and started raising `ArgumentError` in
case of length mismatch of passed strings.
([Pull Request](https://github.com/rails/rails/pull/24510))
* Use SHA-1 to generate non-sensitive digests, such as the ETag header.
([Pull Request](https://github.com/rails/rails/pull/31289),
[Pull Request](https://github.com/rails/rails/pull/31651))
* `assert_changes` will always assert that the expression changes,
regardless of `from:` and `to:` argument combinations.
([Pull Request](https://github.com/rails/rails/pull/31011))
* Add missing instrumentation for `read_multi`
in `ActiveSupport::Cache::Store`.
([Pull Request](https://github.com/rails/rails/pull/30268))
* Support hash as first argument in `assert_difference`.
This allows to specify multiple numeric differences in the same assertion.
([Pull Request](https://github.com/rails/rails/pull/31600))
* Caching: MemCache and Redis `read_multi` and `fetch_multi` speedup.
Read from the local in-memory cache before consulting the backend.

Update "Ruby on Rails 5.2 Release Notes" Guide [ci skip] - Add a description of major features in Rails 5.2. - Add a reference to Pull Request/Commit to every entry in CHANGELOGs, note that some of them combined. - Add section "Ruby on Rails Guides" with notable changes. - Note that - Skipped this since encrypted secrets are already on the way out. ``` * Add `rails secrets:show` command. ([Pull Request](https://github.com/rails/rails/pull/29695)) ``` - Skipped this since it was backported all the way to 5-0-stable. ``` * Make Rails' test runner work better with minitest plugins. ([Pull Request](https://github.com/rails/rails/pull/29572)) ``` Thanks to everyone who has been working on Rails 5.2! <3
