Subject: Switch to LIFO for the connection pool

Using a FIFO for the connection pool can lead to issues when there are
upstream components (pgbouncer, haproxy, etc.) that terminate
connections that are idle after a period of time. Switching to a LIFO
reduces the probability that a thread will checkout a connection that is
about to be closed by an idle timeout in an upstream component.

Subject: Enable query cache on all connection pools

Since the query cache no longer eagerly checks out a connection, we can
enable it on all connection pools at the start of every request, and it
will only take effect for requests that actually use those pools.

Subject:     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.

Subject: activerecord: Remove a redundant mutation tracker

The extra mutation tracker was needed in Rails 5.1 to preserve the
old behaviour of `changes`, but now there is no difference
between `changes` and `changes_to_save`, so `@mutation_tracker`
can be removed.

In the case of remote, it should be the same behavior as submitting
HTML form.

Subject: Don't expose Active Storage routes

These routes are only used internally in Active Storage, and it seems
that there is no need for the user to directly use them.

Therefore, I think that routes should not be exposed to users.

Subject: Update Form Helpers guide to fix example codes [ci skip]

* It looks that example codes are not based on actual output. So I've fixed it.
* Specifically:
  * There are no lines about utf-8 and authenticity_token.
  * The submit button doesn't have data-disabled-with attribute.
  * Each attribute order of html element is different from actual ones.

Subject: Update Layouts and Rendering in Rails [ci skip]

* The example code on this page are similar to ones generated
  by scaffold generator, but some points are different.

* Of course, it is no reason to be as same as scaffolding codes.
  But this is the guide for beginners, I thought it's better
  to be almost same as scaffolding codes.

-### Reachable
-
-A named module is reachable if it is stored in its corresponding constant. It means you can reach the module object via the constant.
-
-That is what ordinarily happens, if a module is called "M", the `M` constant exists and holds it:
-
-```ruby
-module M
-end
-
-M.reachable? # => true
-```
-
-But since constants and modules are indeed kind of decoupled, module objects can become unreachable:
-
-```ruby
-module M
-end
-
-orphan = Object.send(:remove_const, :M)
-
-# The module object is orphan now but it still has a name.
-orphan.name # => "M"
-
-# You cannot reach it via the constant M because it does not even exist.
-orphan.reachable? # => false
-
-# Let's define a module called "M" again.

-# The constant M exists now again, and it stores a module
-# object called "M", but it is a new instance.

Subject: Return `through_scope` only if the scope is not empty scope

Related 2b5f5cdd7c1d95716de6a206b6d09ccbb006dc17.

If `through_scope` is empty scope, it is unnecessary to merge it.
And also, comparing relations is a little expensive (will cause
`build_arel`). It is enough to use `empty_scope?` to determine whether
empty scope.

Subject: Place class level `update`, `destroy`, and `delete` in
 `Persistence::ClassMethods`

The docs are obviously for class level `update`, `destroy`, and
`delete`. It should be placed in `Persistence::ClassMethods` rather than
`Relation`. And also, these methods are not dependent on relation. So it
is not needed to delegate to `all` (plus, `klass.find` is faster than
`relation.find`).

Subject: Ensure returning affected objects for class level `update` and
 `destroy`

Class level `update` and `destroy` are using `find` in the internal, so
it will raise `RecordNotFound` if given ids cannot find an object even
though the method already affect (update or destroy) to any objects.
These methods should return affected objects even in that case.

Subject: Extract `associate_records_to_owner` to refactor
 `Preloader::Association`

Since we have `Preloader#preload`, `Preloader::Association#preload` is a
little confusing. And also, since the `preload` method is an abstract
method, it is hard to read where `associated_records_by_owner` is
called. This refactors `Preloader::Association` to ease to read where
`associated_records_by_owner` is called.

+### Retrying or Discarding failed jobs
+
+It's also possible to retry or discard a job if an exception is raised during execution.
+For example:
+
+```ruby
+class RemoteServiceJob < ActiveJob::Base
+  retry_on CustomAppException # defaults to 3s wait, 5 attempts
+
+  discard_on ActiveJob::DeserializationError
+
+  def perform(*args)
+    # Might raise CustomAppException or ActiveJob::DeserializationError
+  end
+end
+```
+
+To get more details see the API Documentation for [ActiveJob::Exceptions](http://api.rubyonrails.org/classes/ActiveJob/Exceptions/ClassMethods.html).
+
 ### Deserialization
 
 GlobalID allows serializing full Active Record objects passed to `#perform`.

Subject: Use `TOPLEVEL_BINDING` in rails runner command

Binding to capture the local scope. This means that if a constant with same
name as constant specified by the user exists in local scope, constant
defined in local will use. This is different from what the user expects.
Therefore, fixed to use top-level binding instead of local scope.

Fixes #30644

Subject: Prevent extra `column_for` for `change_column_{default,null,comment}`

`change_column_{default,null,comment}` in mysql2 adapter are passing
`column.sql_type` as `type` to `change_column` to intend keeping
previous type. But `column_for` requires extra query, so use passing
`nil` to `type` explicitly in the internal for the purpose.

Subject: Move integer-like primary key normalization to
 `new_column_definition`

Currently the normalization only exists in `primary_key` shorthand. It
should be moved to `new_column_definition` to also affect to
`add_column` with primary key.

Subject: Make bang version work with `InheritableOptions`

Currently, bang version does not work with `InheritableOptions`.
`InheritableOptions` treats the argument Hash as the default value.
However, `Hash#fetch` does not use the default value when key is not
found, so can not get the default value.
So in bang version, should use `Hash#[]` instead of `Hash#fetch`.

-### Session Storage
+### Encrypted Session Storage
 
 NOTE: _Rails provides several storage mechanisms for the session hashes. The most important is `ActionDispatch::Session::CookieStore`._
 
-Rails 2 introduced a new default session storage, CookieStore. CookieStore saves the session hash directly in a cookie on the client-side. The server retrieves the session hash from the cookie and eliminates the need for a session ID. That will greatly increase the speed of the application, but it is a controversial storage option and you have to think about the security implications of it:
+The `CookieStore` saves the session hash directly in a cookie on the
+client-side. The server retrieves the session hash from the cookie and
+eliminates the need for a session ID. That will greatly increase the
+speed of the application, but it is a controversial storage option and
+you have to think about the security implications and storage
+limitations of it:
+
+* Cookies imply a strict size limit of 4kB. This is fine as you should
+  not store large amounts of data in a session anyway, as described
+  before. Storing the current user's database id in a session is common
+  practice.
+
+* Session cookies do not invalidate themselves and can be maliciously
+  reused. It may be a good idea to have your application invalidate old
+  session cookies using a stored timestamp.
+
+The `CookieStore` uses the
+[encrypted](http://api.rubyonrails.org/classes/ActionDispatch/Cookies/ChainedCookieJars.html#method-i-encrypted)
+cookie jar to provide a secure, encrypted location to store session
+data. Cookie-based sessions thus provide both integrity as well as
+confidentiality to their contents. The encryption key, as well as the
+verification key used for
+[signed](http://api.rubyonrails.org/classes/ActionDispatch/Cookies/ChainedCookieJars.html#method-i-signed)
+cookies, is derived from the `secret_key_base` configuration value.
+
+As of Rails 5.2 encrypted cookies and sessions are protected using AES
+GCM encryption. This form of encryption is a type of Authenticated
+Encryption and couples authentication and encryption in single step
+while also producing shorter ciphertexts as compared to other
+algorithms previously used. The key for cookies encrypted with AES GCM
+are derived using a salt value defined by the
+`config.action_dispatch.authenticated_encrypted_cookie_salt`
+configuration value.
+
+Prior to this version, encrypted cookies were secured using AES in CBC
+mode with HMAC using SHA1 for authentication. The keys for this type of
+encryption and for HMAC verification were derived via the salts defined
+by `config.action_dispatch.encrypted_cookie_salt` and
+`config.action_dispatch.encrypted_signed_cookie_salt` respectively.
+
+Prior to Rails version 4 in both versions 2 and 3, session cookies were
+protected using only HMAC verification. As such, these session cookies
+only provided integrity to their content because the actual session data
+was stored in plaintext encoded as base64. This is how `signed` cookies
+work in the current version of Rails. These kinds of cookies are still
+useful for protecting the integrity of certain client-stored data and
+information.
+
+__Do not use a trivial secret for the `secret_key_base`, i.e. a word
+from a dictionary, or one which is shorter than 30 characters! Instead
+use `rails secret` to generate secret keys!__
+
+It is also important to use different salt values for encrypted and
+signed cookies. Using the same value for different salt configuration
+values may lead to the same derived key being used for different
+security features which in turn may weaken the strength of the key.
 
-* Cookies imply a strict size limit of 4kB. This is fine as you should not store large amounts of data in a session anyway, as described before. _Storing the current user's database id in a session is usually ok_.
+In test and development applications get a `secret_key_base` derived from the app name. Other environments must use a random key present in `config/credentials.yml.enc`, shown here in its decrypted state:
 
-* The client can see everything you store in a session, because it is stored in clear-text (actually Base64-encoded, so not encrypted). So, of course, _you don't want to store any secrets here_. To prevent session hash tampering, a digest is calculated from the session with a server-side secret (`secrets.secret_token`) and inserted into the end of the cookie.
+    secret_key_base: 492f...
 
-In Rails 4, encrypted cookies through AES in CBC mode with HMAC using SHA1 for
-verification was introduced. This prevents the user from accessing and tampering
-the content of the cookie. Thus the session becomes a more secure place to store
-data. The encryption is performed using a server-side `secret_key_base`.
-Two salts are used when deriving keys for encryption and verification. These
-salts are set via the `config.action_dispatch.encrypted_cookie_salt` and
-`config.action_dispatch.encrypted_signed_cookie_salt` configuration values.
+If you have received an application where the secret was exposed (e.g. an application whose source was shared), strongly consider changing the secret.
 
-Rails 5.2 uses AES-GCM for the encryption which couples authentication
-and encryption in one faster step and produces shorter ciphertexts.
+### Rotating Keys for Encrypted and Signed Cookies
 
-Encrypted cookies are automatically upgraded if the
-`config.action_dispatch.use_authenticated_cookie_encryption` is enabled.
+It is possible to rotate the `secret_key_base` as well as the salts,
+ciphers, and digests used for both encrypted and signed cookies. Rotating
+the `secret_key_base` is necessary if the value was exposed or leaked.
+It is also useful to rotate this value for other more benign reasons,
+such as an employee leaving your organization or changing hosting
+environments.
 
-_Do not use a trivial secret, i.e. a word from a dictionary, or one which is shorter than 30 characters! Instead use `rails secret` to generate secret keys!_
+Key rotations can be defined through the
+`config.action_dispatch.cookies_rotations` configuration value. This
+value is set to an instance of
+[RotationConfiguration](http://api.rubyonrails.org/classes/ActiveSupport/RotationConfiguration.html)
+which provides an interface for rotating signed and encrypted cookie
+keys, salts, digests, and ciphers.
 
-In test and development applications get a `secret_key_base` derived from the app name. Other environments must use a random key present in `config/credentials.yml.enc`, shown here in its decrypted state:
+For example, suppose we want to rotate out an old `secret_key_base`, we
+can define a signed and encrypted key rotation as follows:
 
-    secret_key_base: 492f...
+```ruby
+config.action_dispatch.cookies_rotations.rotate :encrypted,
+  cipher: "aes-256-gcm",
+  secret: Rails.application.credentials.old_secret_key_base,
+  salt: config.action_dispatch.authenticated_encrypted_cookie_salt
 
-If you have received an application where the secret was exposed (e.g. an application whose source was shared), strongly consider changing the secret.
+config.action_dispatch.cookies_rotations.rotate :signed,
+  digest: "SHA1",
+  secret: Rails.application.credentials.old_secret_key_base,
+  salt: config.action_dispatch.signed_cookie_salt
+```
+
+Multiple rotations are possible by calling `rotate` multiple times. For
+example, suppose we want to use SHA512 for signed cookies while rotating
+out SHA256 and SHA1 digests using the same `secret_key_base`
+
+```ruby
+config.action_dispatch.signed_cookie_digest = "SHA512"
+
+config.action_dispatch.cookies_rotations.rotate :signed,
+  digest: "SHA256",
+  secret: Rails.application.credentials.secret_key_base,
+  salt: config.action_dispatch.signed_cookie_salt
+
+config.action_dispatch.cookies_rotations.rotate :signed,
+  digest: "SHA1",
+  secret: Rails.application.credentials.secret_key_base,
+  salt: config.action_dispatch.signed_cookie_salt
+```
+
+For more details on key rotation with encrypted and signed messages as
+well as the various options the `rotate` method accepts, please refer to
+the
+[MessageEncryptor API](api.rubyonrails.org/classes/ActiveSupport/MessageEncryptor.html)
+and
+[MessageVerifier API](api.rubyonrails.org/classes/ActiveSupport/MessageVerifier.html)
+documentation.

From b5aa2e0c495b310cbef90b2185ef28cd00745b23 Mon Sep 17 00:00:00 2001
From: Kasper Timm Hansen <kaspth@gmail.com>

Subject: Remove advanced key generator rotations from verifier/encryptor.

Noticed that verifiers and encryptors never once mentioned key generators
and salts but only concerned themselves with generated secrets.

Clears up the confusing naming around raw_key and secret as well. And
makes the rotation API follow the constructor signature to the letter.

Subject: [ci skip] Attempt a new explanation for rotations.

It's become clear to me that the use case is still a bit muddy
and the upgrade path is going to be tough for people to figure
out.

This attempts at understanding it better through documentation,
but still needs follow up work.

+For example to rotate out an old `secret_key_base`, we can define signed and
+encrypted rotations as follows:
 
 ```ruby
-config.action_dispatch.cookies_rotations.rotate :encrypted,
-  cipher: "aes-256-gcm",
-  secret: Rails.application.credentials.old_secret_key_base,
-  salt: config.action_dispatch.authenticated_encrypted_cookie_salt
-
-config.action_dispatch.cookies_rotations.rotate :signed,
-  digest: "SHA1",
-  secret: Rails.application.credentials.old_secret_key_base,
-  salt: config.action_dispatch.signed_cookie_salt
+Rails.application.config.action_dispatch.cookies_rotations.tap do |cookies|
+  cookies.rotate :encrypted, secret: Rails.application.credentials.old_secret_key_base
+  cookies.rotate :signed,    secret: Rails.application.credentials.old_secret_key_base
+end
 ```
 
-Multiple rotations are possible by calling `rotate` multiple times. For
-example, suppose we want to use SHA512 for signed cookies while rotating
-out SHA256 and SHA1 digests using the same `secret_key_base`:
+It's also possible to set up multiple rotations. For instance to use `SHA512`
+for signed cookies while rotating out SHA256 and SHA1 digests, we'd do:
 
 ```ruby
-config.action_dispatch.signed_cookie_digest = "SHA512"
+Rails.application.config.action_dispatch.signed_cookie_digest = "SHA512"
 
-config.action_dispatch.cookies_rotations.rotate :signed,
-  digest: "SHA256",
-  secret: Rails.application.credentials.secret_key_base,
-  salt: config.action_dispatch.signed_cookie_salt
-
-config.action_dispatch.cookies_rotations.rotate :signed,
-  digest: "SHA1",
-  secret: Rails.application.credentials.secret_key_base,
-  salt: config.action_dispatch.signed_cookie_salt
+Rails.application.config.action_dispatch.cookies_rotations.tap do |cookies|
+  cookies.rotate :signed, digest: "SHA256"
+  cookies.rotate :signed, digest: "SHA1"
+end
 ```
 
+While you can setup as many rotations as you'd like it's not common to have many
+rotations going at any one time.

 well as the various options the `rotate` method accepts, please refer to

Subject: Preload digest/sha2 to avoid thread safe error.

I got this error in production using Puma in multi-threaded mode:

```
RuntimeError: Digest::Base cannot be directly inherited in Ruby
from active_support/security_utils.rb:23:in `variable_size_secure_compare'
from active_support/security_utils.rb:23:in `hexdigest'
from active_support/security_utils.rb:23:in `digest'
```

Looks like Digest uses const_missing to load Digest::SHA256 (https://github.com/ruby/ruby/blob/trunk/ext/digest/lib/digest.rb#L8)

Subject: Fix cookies/session tests broken after merging key rotation.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Based on, yet closes https://github.com/rails/rails/pull/30708

Fix the session test by properly truncating the legacy encryption
key for cbc encryption. Borrowed straight from 👆.

Fix the cookies test a little differently than the PR. Basically
keep every config within the config block.

 If you have received an application where the secret was exposed (e.g. an application whose source was shared), strongly consider changing the secret.
 
-### Rotating Keys for Encrypted and Signed Cookies
+### Rotating Encrypted and Signed Cookies Configurations
 
-It is possible to rotate the `secret_key_base` as well as the salts,
-ciphers, and digests used for both encrypted and signed cookies. Rotating
-the `secret_key_base` is necessary if the value was exposed or leaked.
-It is also useful to rotate this value for other more benign reasons,
-such as an employee leaving your organization or changing hosting
-environments.
+Rotation is ideal for changing cookie configurations and ensuring old cookies
+aren't immediately invalid. Your users then have a chance to visit your site,
+get their cookie read with an old configuration and have it rewritten with the
+new change. The rotation can then be removed once you're comfortable enough
+users have had their chance to get their cookies upgraded.
 
-For example to rotate out an old `secret_key_base`, we can define signed and
-encrypted rotations as follows:
+It's possible to rotate the ciphers and digests used for encrypted and signed cookies.
+
+For instance to change the digest used for signed cookies from SHA1 to SHA256,
+you would first assign the new configuration value:
 
 ```ruby
-Rails.application.config.action_dispatch.cookies_rotations.tap do |cookies|
-  cookies.rotate :encrypted, secret: Rails.application.credentials.old_secret_key_base
-  cookies.rotate :signed,    secret: Rails.application.credentials.old_secret_key_base
-end
+Rails.application.config.action_dispatch.signed_cookie_digest = "SHA256"
 ```
 
-It's also possible to set up multiple rotations. For instance to use `SHA512`
-for signed cookies while rotating out SHA256 and SHA1 digests, we'd do:
+Then you'd set up a rotation with the old configuration to keep it alive.
 
 ```ruby
-Rails.application.config.action_dispatch.signed_cookie_digest = "SHA512"
-
 Rails.application.config.action_dispatch.cookies_rotations.tap do |cookies|
   cookies.rotate :signed, digest: "SHA256"
-  cookies.rotate :signed, digest: "SHA1"
 end
 ```
 
+Then any written signed cookies will be digested with SHA256. Old cookies
+that were written with SHA1 can still be read, and if accessed will be written
+with the new digest so they're upgraded and won't be invalid when you remove the
+rotation.
+
+Once users with SHA1 digested signed cookies should no longer have a chance to
+have their cookies rewritten, remove the rotation.
+
 While you can setup as many rotations as you'd like it's not common to have many
 rotations going at any one time.

Subject: Change :github git source for bug report templates

:github source uses `git://` url by default, `https://` is recommended.
See http://bundler.io/v1.15/guides/git.html#security

We do the same in our `Gemfile` and templates.

Subject: `Postgres::OID::Range` serializes to a `Range`, quote in `Quoting`

PostgreSQL 9.1+ introduced range types, and Rails added support for
using this datatype in ActiveRecord. However, the serialization of
`PostgreSQL::OID::Range` was incomplete, because it did not properly
quote the bounds that make up the range. A clear example of this is a
`tsrange`.

Normally, ActiveRecord quotes Date/Time objects to include the
milliseconds. However, the way `PostgreSQL::OID::Range` serialized its
bounds, the milliseconds were dropped. This meant that the value was
incomplete and not equal to the submitted value.

An example of normal timestamps vs. a `tsrange`. Note how the bounds
for the range do not include their milliseconds (they were present in
the ruby Range):

    UPDATE "iterations" SET "updated_at" = $1, "range" = $2 WHERE
    "iterations"."id" = $3
    [["updated_at", "2017-09-23 17:07:01.304864"],
    ["range", "[2017-09-23 00:00:00 UTC,2017-09-23 23:59:59 UTC]"],
    ["id", 1234]]

`PostgreSQL::OID::Range` serialized the range by interpolating a
string for the range, which works for most cases, but does not work
for timestamps:

    def serialize(value)
      if value.is_a?(::Range)
        from = type_cast_single_for_database(value.begin)
        to = type_cast_single_for_database(value.end)
        "[#{from},#{to}#{value.exclude_end? ? ')' : ']'}"
      else
        super
      end
    end

    (byebug) from = type_cast_single_for_database(value.begin)
    2010-01-01 13:30:00 UTC

    (byebug) to = type_cast_single_for_database(value.end)
    2011-02-02 19:30:00 UTC

    (byebug) "[#{from},#{to}#{value.exclude_end? ? ')' : ']'}"
    "[2010-01-01 13:30:00 UTC,2011-02-02 19:30:00 UTC)"

@sgrif (the original implementer for Postgres Range support) provided
some feedback about where the quoting should occur:

  Yeah, quoting at all is definitely wrong here. I'm not sure what I
  was thinking in 02579b5, but what this is doing is definitely in the
  wrong place. It should probably just be returning a range of
  subtype.serialize(value.begin) and subtype.serialize(value.end), and
  letting the adapter handle the rest.

`Postgres::OID::Range` now returns a `Range` object, and
`ActiveRecord::ConnectionAdapters::PostgreSQL::Quoting` can now encode
and quote a `Range`:

    def encode_range(range)
      "[#{type_cast(range.first)},#{type_cast(range.last)}#{range.exclude_end? ? ')' : ']'}"
    end

    ...

    encode_range(range)
    #=> "['2010-01-01 13:30:00.670277','2011-02-02 19:30:00.745125')"

This commit includes tests to make sure the milliseconds are
preserved in `tsrange` and `tstzrange` columns

Subject: Ensure `HashWithIndifferentAccess#transform_keys` to return
 `HashWithIndifferentAccess`

Currently, `#transform_values`, `#select` and `#reject` return instance
of `HashWithIndifferentAccess`. But `#transform_keys` returns instance
of Hash. This behavior is a bit confusing.

I think that `HashWithIndifferentAccess#transform_keys` should also return
instance of `HashWithIndifferentAccess` as well as other methods.

Subject: Encourage html-safe API in layouts/rendering guide

While the code example was not unsafe, it
encourages the use of confusingly unsafe APIs
(specifically `html_safe`). We have a safe
alternative and we should encourage people to use
it under all circumstances.

Subject: Deprecate secret_token, long since usurped by secret_key_base.

See the changelog entry.

Remove `secrets.secret_token` from the bug report templates,
since we don't accept bug reports for Rails versions that
don't support a `secret_key_base`.

+*   Deprecate `secrets.secret_token`.
+
+    The architecture for secrets had a big upgrade between Rails 3 and Rails 4,
+    when the default changed from using `secret_token` to `secret_key_base`.
+
+    `secret_token` has been soft deprecated in documentation for four years
+    but is still in place to support apps created before Rails 4.
+    Deprecation warnings have been added to help developers upgrade their
+    applications to `secret_key_base`.
+
+    *claudiob*, *Kasper Timm Hansen*
+
 *   Return an instance of `HashWithIndifferentAccess` from `HashWithIndifferentAccess#transform_keys`.

+# extracting its first frame, and a PDF blob can be previewed by extracting its first page.
+#
+# A previewer extracts a preview image from a blob. Active Storage provides previewers for videos and PDFs:
+# ActiveStorage::Previewer::VideoPreviewer and ActiveStorage::Previewer::PDFPreviewer. Build custom previewers by
+# subclassing ActiveStorage::Previewer and implementing the requisite methods. Consult the ActiveStorage::Previewer
+# documentation for more details on what's required of previewers.
+#
+# To choose the previewer for a blob, Active Storage calls +accept?+ on each registered previewer in order. It uses the
+# first previewer for which +accept?+ returns true when given the blob. In a Rails application, add or remove previewers
+# by manipulating +Rails.application.config.active_storage.previewers+ in an initializer:
+#
+#   Rails.application.config.active_storage.previewers
+#   # => [ ActiveStorage::Previewer::PDFPreviewer, ActiveStorage::Previewer::VideoPreviewer ]
+#
+#   # Add a custom previewer for Microsoft Office documents:
+#   Rails.application.config.active_storage.previewers << DOCXPreviewer
+#   # => [ ActiveStorage::Previewer::PDFPreviewer, ActiveStorage::Previewer::VideoPreviewer, DOCXPreviewer ]
+#
+# Outside of a Rails application, modify +ActiveStorage.previewers+ instead.

+#
+#   * {ffmpeg}[https://www.ffmpeg.org]
+#   * {mupdf}[https://mupdf.com]

Subject: Fix "warning: method redefined; discarding old
 test_scaffold_plural_names"

Since warning was issued due to duplication of test names, fix the test
name to a meaningful name.

This fixes following warnings:

```
railties/test/generators/named_base_test.rb:141: warning: method redefined; discarding old test_scaffold_plural_names
railties/test/generators/named_base_test.rb:62: warning: previous definition of test_scaffold_plural_names was here

Subject: Don't use Active Support where it is not needed.

This code has been changed with https://github.com/rails/rails/pull/30735/files#diff-8e5f6b33c191ad6dec07f3288345a13fL47.

However, `active_support/time` is not load automatically, so if use
Action Pack alone, `days` method can not use and an error occurs.
In this case, I think that there is no problem by specifying a value
with Integer.

Subject: Remove `:api:` tag that has leaked on the doc directly [ci skip]

Currently `:api:` tag has leaked on the doc directly since RDoc doesn't
support `:api:` tag directive.

http://api.rubyonrails.org/v5.1/classes/AbstractController/Rendering.html

So `:api: private` doesn't work as expected. We are using `:nodoc:` for
the purpose.

Related #13989.

 INFO: _A CAPTCHA is a challenge-response test to determine that the response is not generated by a computer. It is often used to protect registration forms from attackers and comment forms from automatic spam bots by asking the user to type the letters of a distorted image. This is the positive CAPTCHA, but there is also the negative CAPTCHA. The idea of a negative CAPTCHA is not for a user to prove that they are human, but reveal that a robot is a robot._
 
-A popular positive CAPTCHA API is [reCAPTCHA](http://recaptcha.net/) which displays two distorted images of words from old books. It also adds an angled line, rather than a distorted background and high levels of warping on the text as earlier CAPTCHAs did, because the latter were broken. As a bonus, using reCAPTCHA helps to digitize old books. [ReCAPTCHA](https://github.com/ambethia/recaptcha/) is also a Rails plug-in with the same name as the API.

 You will get two keys from the API, a public and a private key, which you have to put into your Rails environment. After that you can use the recaptcha_tags method in the view, and the verify_recaptcha method in the controller. Verify_recaptcha will return false if the validation fails.
 The problem with CAPTCHAs is that they have a negative impact on the user experience. Additionally, some visually impaired users have found certain kinds of distorted CAPTCHAs difficult to read. Still, positive CAPTCHAs are one of the best methods to prevent all kinds of bots from submitting forms.

Subject: Make automatically synchronize test schema work inside engine

In Rails engine, migration files are in under `db/migrate` of engine.
Therefore, when rake task is executed in engine, `db/migrate` is
automatically added to `DatabaseTasks.migrations_paths`.
https://github.com/rails/rails/blob/a18cf23a9cbcbeed61e8049442640c7153e0a8fb/activerecord/lib/active_record/railtie.rb#L39..L43

However, if execute the rake task under dummy app, migration files will not
be loaded because engine's migration path setting process is not called.

Therefore, in order to load migration files correctly, it is necessary to
execute rake task under engine.

Fixes #30765

especially in the Ruby community, some people still use NPM (and,
really, ES2015+ syntax has nothing to do with NPM or Yarn).

Subject: Implement H2 Early Hints for Rails

When puma/puma#1403 is merged Puma will support the Early Hints status
code for sending assets before a request has finished.

While the Early Hints spec is still in draft, this PR prepares Rails to
allowing this status code.

If the proxy server supports Early Hints, it will send H2 pushes to the
client.

This PR adds a method for setting Early Hints Link headers via Rails,
and also automatically sends Early Hints if supported from the
`stylesheet_link_tag` and the `javascript_include_tag`.

Once puma supports Early Hints the `--early-hints` argument can be
passed to the server to enable this or set in the puma config with
`early_hints(true)`. Note that for Early Hints to work
in the browser the requirements are 1) a proxy that can handle H2,
and 2) HTTPS.

To start the server with Early Hints enabled pass `--early-hints` to
`rails s`.

This has been verified to work with h2o, Puma, and Rails with Chrome.

The commit adds a new option to the rails server to enable early hints
for Puma.

Early Hints spec:

Subject: Replace variation key use with SHA256 of key to prevent long
 filenames

If a variant has a large set of options associated with it, the generated
filename will be too long, causing Errno::ENAMETOOLONG to be raised. This
change replaces those potentially long filenames with a much more compact
SHA256 hash. Fixes #30662.

In addition, there's a new rake task, `rake rails:update:application_controller` to do this automatically for you - and it will be run as part of the normal `rake rails:update` process.

 Rails can now provide localized views, depending on the locale that you have set. For example, suppose you have a `Posts` controller with a `show` action. By default, this will render `app/views/posts/show.html.erb`. But if you set `I18n.locale = :da`, it will render `app/views/posts/show.da.html.erb`. If the localized template isn't present, the undecorated version will be used. Rails also includes `I18n#available_locales` and `I18n::SimpleBackend#available_locales`, which return an array of the translations that are available in the current Rails project.

 `Blob` models store attachment metadata (filename, content-type, etc.), and their identifier key in the storage service. Blob models do not store the actual binary data. They are intended to be immutable in spirit. One file, one blob. You can associate the same blob with multiple application models as well. And if you want to do transformations of a given `Blob`, the idea is that you'll simply create a new one, rather than attempt to mutate the existing one (though of course you can delete the previous version later if you don't need it).

Subject: Distinguish missing adapter gems from load errors within the adapter

* When the adapter is missing, raise an exception that points out config
  typos and missing Gemfile entries. (We can assume that a non-builtin
  adapter was used since these are always available.)
* When loading an adapter raises a LoadError, prefix its error message
  to indicate that the adapter is likely missing an optional dependency.

From: Jeremy Daer <jeremydaer@gmail.com>
Date: Thu, 28 Sep 2017 21:54:00 -0700
Subject: redis-rb 4.0 support

* Use `gem 'redis', '~> 4.0'` for new app Gemfiles
* Loosen Action Cable redis-rb dep to `>= 3.3, < 5`
* Bump redis-namespace for looser Redis version dep
* Avoid using the underlying `redis.client` directly
* Use `Redis.new` instead of `Redis.connect`

-Dealing with Ajax events
-------------------------
-
-Here are the different events that are fired when you deal with elements
-that have a `data-remote` attribute:
-
-NOTE: All handlers bound to these events are always passed the event object as the
-first argument. The table below describes the extra parameters passed after the
-event argument. For example, if the extra parameters are listed as `xhr, settings`,
-then to access them, you would define your handler with `function(event, xhr, settings)`.
-
-| Event name          | Extra parameters | Fired                                                       |
-|---------------------|------------------|-------------------------------------------------------------|
-| `ajax:before`       |                  | Before the whole ajax business, aborts if stopped.          |
-| `ajax:beforeSend`   | xhr, options     | Before the request is sent, aborts if stopped.              |
-| `ajax:send`         | xhr              | When the request is sent.                                   |
-| `ajax:success`      | xhr, status, err | After completion, if the response was a success.            |
-| `ajax:error`        | xhr, status, err | After completion, if the response was an error.             |
-| `ajax:complete`     | xhr, status      | After the request has been completed, no matter the outcome.|
-| `ajax:aborted:file` | elements         | If there are non-blank file inputs, aborts if stopped.      |
-
-### Stoppable events
-
-If you stop `ajax:before` or `ajax:beforeSend` by returning false from the
-handler method, the Ajax request will never take place. The `ajax:before` event
-is also useful for manipulating form data before serialization. The

-If you stop the `ajax:aborted:file` event, the default behavior of allowing the

Subject: Fix test name for daemon option test

In this test file, "server option" refers to the server used to start
Rails(e.g. `puma`, `thin`).
But this test, "server option" is not specified. Therefore, I think that
it is incorrect that `server_option` is included in the test name.

This is the fix for the regression of #29848.

In #29848, I've kept existing select list in the subquery for the count
if ORDER BY is given. But it had accidentally affect to GROUP BY
queries also. It should keep the previous behavior in that case.

Fixes #30886.

primary key, but also for composite primary key. In that case,
`auto_increment: true` should be dumped explicitly in the
`db/schema.rb`.

Fixes #30894.

Subject: Fix longer sequence name detection for serial columns (#28339)

We already found the longer sequence name, but we could not consider
whether it was the sequence name created by serial type due to missed a
max identifier length limitation. I've addressed the sequence name
consideration to respect the max identifier length.

Fixes #28332.

Subject: Add a test case that eager-loading with a polymorphic association and
 using `exists?`

This test covers the case of 02da8aea.

Previously `exists?` was always eager-loading the includes values. But
now it is eager-loaded only when necessary since 07a611e0.

So the case of the eager-loading had not covered in the test.

Subject: `ActiveRecord::Tasks::DatabaseTasks.load_schema` has always to
 establish database connection

  When load schema from `structure.sql`, database connection isn't
  established. `ActiveRecord::Tasks::DatabaseTasks.load_schema` has to
  establish database connection since it executes
  ```
  ActiveRecord::InternalMetadata.create_table
  ActiveRecord::InternalMetadata[:environment] = environment
  ```

 I18n support in Ruby on Rails was introduced in the release 2.2 and is still evolving.

Subject: Start bringing attributes API to AM

This is the first PR of a WIP to bring the attributes API to
ActiveModel.  It is not yet ready for public API.

The `attributes_dirty_test.rb` file was created based on `dirty_test.rb`,
and the simplifications in the diff do much to motivate this change.

Subject: Keep `:api: plugin` methods in the doc [ci skip]

`:api:` tag was removed in 5349f231 since RDoc doesn't support `:api:`
tag. But those methods are not private API, they are public API for
renderers. The renderers should be able to know that they can override
this method.

Subject: Let Hash#slice return a Hash

In order to keep this method compatible with the Ruby 2.5 version of Hash#slice.

but it might not cause a real problem, since HWIA, the biggest use case of Hash subclassing here,
already overrides `slice` to return another HWIA.

Subject: Avoid slicing from Thor's original HWIA

Because `options` here is not AS::HWIA but an instance of Thor::CoreExt::HWIA
that looks very similar to ours but behaves slightly different, we need to keep
this object be an instance of Thor::CoreExt::HWIA.
Since Ruby 2.5 has Hash#slice that returns a new Hash instance now,
we need to avoid calling `slice` on this tricky object.

The default adapter in new Rails applications is the asynchronous (`async`) adapter.

acts_like?

Add a case statement to use direct symbols instead of string
interpolation for the three scenarios I found in the Rails codebase:
time, date, and string.

For time/date/string, this change prevents two string allocations for
each time the method is called and speeds up the method by ~2.7x. For
other arguments, there is no memory difference and performance
difference is within margin of error.

Subject: Remove `supports_disable_referential_integrity?`

`supports_disable_referential_integrity?` used to handle
if PostgreSQL database supports
`ALTER TABLE <table name> DISABLE/ENABLE TRIGGER` statements.
Refer https://github.com/rails/rails/commit/9a947af0e79cfb8692eb7e5ae94c1b8c40756f49

These statements have been documented since 8.1.

https://www.postgresql.org/docs/8.1/static/sql-altertable.html
> DISABLE/ENABLE TRIGGER

Now Rails supports PostgreSQL 9.1 or higher only.
No need to handle `supports_disable_referential_integrity?` anymore.
Also, this method does not exist in any other adapters including AbstractAdapter.

Subject: Cache regexps generated from acronym_regex

The Problem
-----------

The following line from `String#camelize`:

  string = string.sub(/^(?:#{inflections.acronym_regex}(?=\b|[A-Z_])|\w)/) { |match| match.downcase }

and the following line from `String#camelize`:

  word.gsub!(/(?:(?<=([A-Za-z\d]))|\b)(#{inflections.acronym_regex})(?=\b|[^a-z])/) { "#{$1 && '_'.freeze }#{$2.downcase}" }#{$2.downcase}" }

Both generate the same regexep in the first part of the `.sub`/`.gsub`
method calls every time the function is called, creating an extra object
allocation each time.  The value of `acronym_regex` only changes if the
user decides add an acronym to the current set of inflections and apends
another string on the the regexp generated here, but beyond that it
remains relatively static.

This has been around since acronym support was introduced back in 2011
in PR#1648.

Proposed Solution
-----------------
To avoid re-generating these strings every time these methods are
called, cache the values of these regular expressions in the
`ActiveSupport::Inflector::Inflections` instance, making it so these
regular expressions are only generated once, or when the acronym's are
added to.

Other notable changes is the attr_readers are nodoc'd, as they shouldn't
really be public APIs for users.  Also, the new method,
define_acronym_regex_patterns, is the only method in charge of
manipulating @acronym_regex, and initialize_dup also makes use of that
new change.

** Note about fix for non-deterministic actionpack test **

With the introduction of `@acronym_underscore_regex` and
`@acronym_camelize_regex`, tests that manipulated these for a short
time, then reset them could caused test failures to happen.  This
happened because the previous way we reset the `@acronyms` and
`@acronym_regex` was the set them using #instance_variable_set, which
wouldn't run the #define_acronym_regex_patterns method.

This has now been introduced into the actionpack tests to avoid this
failure.

 INFO: The following calculation methods have edge cases in October 1582, since days 5..14 just do not exist. This guide does not document their behavior around those days for brevity, but it is enough to say that they do what you would expect. That is, `Date.new(1582, 10, 4).tomorrow` returns `Date.new(1582, 10, 15)` and so on. Please check `test/core_ext/date_ext_test.rb` in the Active Support test suite for expected behavior.

Subject: Change `VENDOR_PATH` to `APP_ROOT` in `bin/yarn`

This variable was initially used to hold the vendor directory.
https://github.com/rails/rails/commit/3dac36b

Therefore, the variable name `VENDOR_PATH` was appropriate.
However, `package.json` is now placed in the root of the project.
https://github.com/rails/rails/commit/8e9e943

Therefore, like other bin scripts, I think the variable name `APP_ROOT`
is appropriate.
https://github.com/rails/rails/blob/2c845f6b03ddf2aa233b00385d24d769a4a34fa6/railties/lib/rails/generators/rails/app/templates/bin/setup.tt#L5

Subject: Prevent extra string allocations when no 'rel' arg passed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Do a check if the 'rel' argument is passed in, and simply set it to
'nofollow' if 'rel' was not passed in. This prevents three string
allocations for each call to `link_to` in that scenario. In the scenario
where the 'rel' argument is passed in, performance is around the same as
before as the `key?` check is very fast.

```ruby
begin
  require "bundler/inline"
rescue LoadError => e
  $stderr.puts "Bundler version 1.10 or later is required. Please update
                your Bundler"
  raise e
end

gemfile(true) do
  source "https://rubygems.org"

  gem "benchmark-ips"
  gem "rails"
end

def allocate_count
  GC.disable
  before = ObjectSpace.count_objects
  yield
  after = ObjectSpace.count_objects
  after.each { |k,v| after[k] = v - before[k] }
  after[:T_HASH] -= 1 # probe effect - we created the before hash.
  GC.enable
  result = after.reject { |k,v| v == 0 }
  GC.start
  result
end

@hash = {}

def master_version
  "#{@hash['rel'.freeze]} nofollow".lstrip
end

def fast_version
  if @hash.key?('rel'.freeze)
    "#{@hash["rel"]} nofollow".lstrip
  else
    "nofollow".freeze
  end
end

puts 'no rel key'

puts "master_version"
puts allocate_count { 1000.times { master_version } }
puts "fast_version"
puts allocate_count { 1000.times { fast_version } }

Benchmark.ips do |x|
  x.report("master_version") { master_version }
  x.report("fast_version")     { fast_version }
  x.compare!
end

puts 'rel key'

@hash['rel'] = 'hi'.freeze

puts "master_version"
puts allocate_count { 1000.times { master_version } }
puts "fast_version"
puts allocate_count { 1000.times { fast_version } }

Subject: Deprecate ActiveSupport::Inflector#acronym_regex

To be removed in Rails 6.0 (default for the deprecate helper).  Code
moved around as well for the ActiveSupport::Deprecation modules, since
it was dependent on ActiveSupport::Inflector being loaded for it to
work.  By "lazy loading" the Inflector code from within the Deprecation
code, we can require ActiveSupport::Deprecation from
ActiveSupport::Inflector and not get a circular dependency issue.

Subject: `source_type_scope` should respect correct table alias

`join_scopes` in `PolymorphicReflection` is passed aliased `table`, so
it should be respected for `source_type_scope`.

Closes #13969.
Fixes #13920.
Fixes #15190.

Subject: Address incorrect number of queries executed at Oracle enhanced
 adapter

This pull request addresses these 17 failures when tested with Oracle enhanced adapter.
All of these failures are due to the incorrect number of queries. Here is the first one.

```ruby
$ ARCONN=oracle bin/test test/cases/nested_attributes_test.rb:1086
Using oracle
Run options: --seed 27985

F

Finished in 0.874514s, 1.1435 runs/s, 1.1435 assertions/s.

  1) Failure:
TestHasManyAutosaveAssociationWhichItselfHasAutosaveAssociations#test_circular_references_do_not_perform_unnecessary_queries [/home/yahonda/git/rails/activerecord/test/cases/nested_attributes_test.rb:1086]:
6 instead of 3 queries were executed.
Queries:

```

Since https://github.com/rsim/oracle-enhanced/pull/1490 Oracle enhanced adapter drops its own schema caching called OracleEnhancedAdapter.cache_columns` to use Rails scehema cache
generated by `db:schema:cache:dump`.

By this change some extra sql statements executed at ActiveRecord unit test, which can be
fixed by adding the sql statement to `oracle_ignored`.

Subject: Ignore "gem "bundler" cannot be uninstalled because it is a default
 gem" error when tested with ruby-head

This pull request attempts to ignore the following error
when tested with ruby-head which has bundler as a default gem.

```ruby
$ rvm @global do gem uninstall bundler --all --ignore-dependencies --executables
ERROR:  While executing gem ... (Gem::InstallError)

    gem "bundler" cannot be uninstalled because it is a default gem

The command "rvm @global do gem uninstall bundler --all --ignore-dependencies --executables" failed and exited with 1 during .
```

Refer https://travis-ci.org/rails/rails/jobs/295600391

This workaround should be removed once https://github.com/bundler/bundler/issues/6072 is addressed.

In `AVLogSubscriberTest`, if the `Rails.root` is not defined, define the
method and undef it in teardown.
https://github.com/rails/rails/blob/master/actionview/test/template/log_subscriber_test.rb#L21..L33

However, in `bin/test`, `Rails.root` is defined, which results in referring to
uninitialized variables and warnings.

Subject: Specify bundler version in template files

We have already specified to install `bundler` 1.15.4 in `.travis.yml`.
https://github.com/rails/rails/blob/master/.travis.yml#L31..L32

However, `bundler` 1.16.0 may be used in the test.
https://travis-ci.org/rails/rails/jobs/296582467#L2208

The test failed due to this influence.
In order to avoid this, specifying `bundler` version in bug report
templates.

Subject: Generate the correct path in nested scaffold generator

Currently, namespaced scaffold generator will generate an incorrect path
and the generated file will not work properly.

```
$ ./bin/rails g scaffold admin/user
$ ./bin/rails db:migrate
$  ./bin/rails t test/controllers
# Running:

E

Error:
Admin::UsersControllerTest#test_should_create_admin_user:
NameError: undefined local variable or method `admin_admin_users_url' for #<Admin::UsersControllerTest:0x000055a59f25ff68>
Did you mean?  admin_users
    test/controllers/admin/users_controller_test.rb:20:in `block (2 levels) in <class:UsersControllerTest>'
    test/controllers/admin/users_controller_test.rb:19:in `block in <class:UsersControllerTest>'

bin/rails test test/controllers/admin/users_controller_test.rb:18
```

This is because combine `controller_class_path` and `singular_table_name`
to generate route.
https://github.com/rails/rails/blob/360698aa245b45349d1d1b12e1afb34759515e69/railties/lib/rails/generators/named_base.rb#L172

Normally, if using namspaced generator, table name already contains
namespace. Therefore, adding `controller_class_path` adds extra namespace.
Since it is special only when explicitly specifying `model-name`, it is
modified to change the value only when `model-name`is specified.

Follow up of #30729

Subject: Show `RequestForgeryProtection` methods in api doc  [ci skip]

Several methods of `RequestForgeryProtection` are not showed in the api
doc even though `:doc:` is specified.
(e.g. `form_authenticity_param`)
http://api.rubyonrails.org/classes/ActionController/RequestForgeryProtection.html

These methods are listed in the doc of v4.1.
http://api.rubyonrails.org/v4.1/classes/ActionController/RequestForgeryProtection.html

This is due to the influence of `:nodoc:` added in #18102, methods after
 `CROSS_ORIGIN_JAVASCRIPT_WARNING` not showed from the doc.
Therefore, in order to show the method like originally, added `startdoc`
after `CROSS_ORIGIN_JAVASCRIPT_WARNING`.

Subject: Ensure `apply_join_dependency` for `update_all` and `delete_all` if
 eager-loading is needed

If a relation has eager-loading values, `count` and `exists?` works
properly, but `update_all` and `delete_all` doesn't work due to missing
`apply_join_dependency`. It should be applied to work consistently.

Fixes #28863.

Subject: Fix preloading polymorphic association when through association has
 already loaded

If through association has already loaded, `source_type` is ignored to
loaded through records. The loaded records should be filtered by
`source_type` in that case.

Fixes #30904.

Subject: Fix preloading polymorphic multi-level through association

This is partially fixed by e617fb57 when through association has already
loaded. Otherwise, second level through association should respect
`preload_scope`.

Fixes #30242.
Closes #30076.

Subject: `scoping` should respect current class and STI constraint (#29199)

A relation includes `klass`, so it can not be used as it is if current
class is different from `current_scope.klass`. It should be created new
relation by current class to respect the klass and STI constraint.

Fixes #17603.
Fixes #23576.

Subject: Explicitly pass window handle to `resize_window_to`

Unlike `resize_window`, `resize_window_to` has three arguments.
https://github.com/thoughtbot/capybara-webkit/blob/d63c3c8e3ae844f0c59359532a6dcb50f4a64d0a/lib/capybara/webkit/driver.rb#L135-L143

Therefore, if pass only width and height just like `resize_window`,
`ArgumentError`will be raised.
To prevent this, explicitly pass window handler.

Subject: Fix acronym support in `humanize`

Acronym inflections are stored with lowercase keys in the hash but
the match wasn't being lowercased before being looked up in the hash.
This shouldn't have any performance impact because before it would
fail to find the acronym and perform the `downcase` operation anyway.

Fixes #31052.

Subject: Resolve Minitest 6 deprecation in assert_no_changes

These changes resolve a deprecation warning in `assert_no_changes`
when asserting that an expression evaluates to `nil` before and after
the passed block is evaluated.

The smallest demonstration of this edge case:

```ruby
assert_no_changes "nil" do
  true # noop
end
```

Under the covers, this is evaluating

```ruby
assert_equal nil, nil
```

Minitest 5 issues a deprecation warning, and Minitest will fail
completely.

For additional context, the motivations and implications of this change
to Minitest have been discussed at length in [seattlerb/minitest#666][].

Subject: Properly check transaction in persistence

```
[NoMethodError]: undefined method `state' for nil:NilClass  Method:[rescue in block in refresh]
```

In `within_new_transaction`, there is the possibility that
`begin_transaction` returns a `nil`. (i.e.: so `transaction = nil`)
So this method is checking `transaction` for nil in 2 spots.

Unfortunately, there is one line that is not checking `transaction` for `nil`
That line, `commit_transaction`, throws an exception for us in AR 5.0.0.1

The problem with the method is finally realized in the error checking itself.
it calls `transaction.state` (i.e.: nil.state) and that is the final exception
raised.

The actual underlying (user) issue is hidden by this line.

Solution is test transaction for nil.

Subject: `rails new` runs `rails active_storage:install`

Omit `rails activestorage:install` for jdbcmysql, jdbc and shebang tests

AppGeneratorTest#test_config_jdbcmysql_database

  rails aborted!
  LoadError: Could not load 'active_record/connection_adapters/mysql_adapter'.
  Make sure that the adapter in config/database.yml is valid.
  If you use an adapter other than 'mysql2', 'postgresql' or 'sqlite3' add
  the necessary adapter gem to the Gemfile.
  (compressed)
  bin/rails:4:in `<main>'
  Tasks: TOP => activestorage:install => environment
  (See full trace by running task with --trace)

AppGeneratorTest#test_config_jdbc_database

  rails aborted!
  LoadError: Could not load 'active_record/connection_adapters/jdbc_adapter'.
  Make sure that the adapter in config/database.yml is valid.
  If you use an adapter other than 'mysql2', 'postgresql' or 'sqlite3' add
  the necessary adapter gem to the Gemfile.

  (See full trace by running task with --trace)

AppGeneratorTest#test_shebang_is_added_to_rails_file

  /home/ubuntu/.rbenv/versions/2.4.1/bin/ruby: no Ruby script found in input (LoadError)

Prevent PendingMigrationError in tests

 * Run `bin/rails db:migrate RAILS_ENV=test` in test_cases before start tests to prevent PendingMigrationError
 * FileUtils.rm_r("db/migrate")
 * --skip-active-storage

Fix failed tests in `railties/test/railties/engine_test.rb`

Related to #30111

Imporve `SharedGeneratorTests#test_default_frameworks_are_required_when_others_are_removed`

 - Explicitly skip active_storage
 - Ensure that skipped frameworks are commented
 - Ensure that default frameworks are not commented

Fix error `Errno::ENOSPC: No space left on device - sendfile`

Since `rails new` runs `rails active_storage:install`
that boots an app.

Since adding Bootsnap 0312a5c67e35b960e33677b5358c539f1047e4e1
during booting an app, it creates the cache:

   264K    tmp/cache/bootsnap-load-path-cache
   27M     tmp/cache/bootsnap-compile-cache

* teardown_app must remove app

Subject: Fix `bin/rails db:migrate` with specified `VERSION`

Ensure that `bin/rails db:migrate` with specified `VERSION` reverts
all migrations only if `VERSION` is `0`.
Raise error if target migration doesn't exist.

+*   Fix `bin/rails db:migrate` with specified `VERSION`.
+    `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.
+
+    *bogdanvlviv*
+
 *   Fixed a bug where column orders for an index weren't written to
     db/schema.rb when using the sqlite adapter.

Subject: Remove useless `associated_records_by_owner`

`associated_records_by_owner` had returned customizing result before
calling `associate_records_to_owner` for through association subclasses.
Since #22115, `associate_records_to_owner` is called in the method and
not returned owner and result pairs. Removing the method will reduce
method call and block call nesting.

Subject: Use plain assert in assert_changes to avoid MT6 refutes

Seeing the previously issued PRs about it, we can avoid the `nil`
comparisons that can happen in `assert_changes` by using plain `assert`
calls.

This is to avoid a deprecation warning about comparing `nil` values in
`assert_equal` for Minitest 5 and a crash in Minitest 6.

You can see the preparations done in [`assert_equal`][ae]. You can also
see that [`assert`][a] does not care about `nil`s.

[ae]: https://github.com/seattlerb/minitest/blob/ca6a71ca901016db09a5ad466b4adea4b52a504a/lib/minitest/assertions.rb#L159-L188

Subject: Do not run `active_storage:install` when bundle install is skipped

In order to execute the `rails` command, need to run bundle install in
advance.
Therefore, if skipped bundle install, `rails` command may fail and
should not do it.

Subject: Allow `Range#include?` on TWZ ranges

In #11474 we prevented TWZ ranges being iterated over which matched
Ruby's handling of Time ranges and as a consequence `include?` stopped
working with both Time ranges and TWZ ranges. However in
ruby/ruby@b061634 support was added for `include?` to use `cover?` for
'linear' objects. Since we have no way of making Ruby consider TWZ
instances as 'linear' we have to override `Range#include?`.

Fixes #30799.

Subject: Run `ConcurrentTransactionTest` if `supports_transaction_isolation?`
 returns true

Not only postgresql or mysql2 adapter, Oracle enhanced adapter
whose default isolation level is read commited, passes these two test cases.

`ConcurrentTransactionTest#test_transaction_per_thread`
`ConcurrentTransactionTest#test_transaction_isolation__read_committed`

```ruby
$ ARCONN=oracle bin/test test/cases/transactions_test.rb:961 -v

```

```ruby
$ ARCONN=oracle bin/test test/cases/transactions_test.rb:979 -v

Also, regardless it is a file based or memory based these tests could fail with SQLite3Adapter.

Subject: Correctly kill the server started with ujs test

`Kernel.#spawn` execute command via the shell if contains shell
metacharacters in the command.
In that case, return value of `spawn` is pid of the shell, not the server.
Therefore, just killing the pid will leave the process of server.

In order to correctly kill the server, send a signal to the process
group, not the process.

Subject: Prevent deadlocks with load interlock and DB lock.

This fixes an issue where competing threads deadlock each other.

- Thread A holds the load interlock but is blocked on getting the DB lock
- Thread B holds the DB lock but is blocked on getting the load interlock (for example when there is a `Model.transaction` block that needs to autoload)

This solution allows for dependency loading in other threads while a thread is waiting to acquire the DB lock.

Fixes #31019

Subject: Fix field_error_proc wrap form select optgroup and divider option tag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

### Summary

The [`:field_error_proc`](https://github.com/rails/rails/blob/master/actionview/lib/action_view/base.rb#L145) is responsible for decorating input tags that refer to attributes with errors. This default build-in rails feature wrap invalid form elements with additional markup: `<div class="field_with_errors">[…]</div>`.

* Fix for `field_error_proc` wraps form select `optgroup`
* Fix for `field_error_proc` wraps form select divider `option`
* Add tests for uncovered elements with errors

[Fixes #31088]

#### Test coverage
* `test_select_grouped_options_with_errors`
* `test_time_zone_select_with_priority_zones_and_errors`

#### Extend test coverage
* `test_collection_select_with_errors`
* `test_label_with_errors`
* `test_check_box_with_errors`
* `test_check_boxes_with_errors`
* `test_radio_button_with_errors`
* `test_radio_buttons_with_errors`
* `test_collection_check_boxes_with_errors`
* `test_collection_radio_buttons_with_errors`

Subject: Add missing requires

Currently, executing the test with only `attribute_set_test.rb` results in an error.

```
./bin/test -w test/cases/attribute_set_test.rb
Run options: --seed 33470

# Running:

E

Error:
ActiveModel::AttributeSetTest#test_#map_returns_a_new_attribute_set_with_the_changes_applied:
NameError: uninitialized constant ActiveModel::AttributeSetTest::AttributeSet
Did you mean?  ActiveModel::Attributes
               ActiveModel::Attribute
    activemodel/test/cases/attribute_set_test.rb:235:in `block in <class:AttributeSetTest>'

bin/test test/cases/attribute_set_test.rb:234
```

Added a missing require to fix this.

Also, I suspect that this is the cause of failures in CI.

Subject: Add missing requires

Currently, executing the test with only `attribute_test.rb` results in an error.

```
./bin/test -w test/cases/attribute_test.rb
Run options: --seed 41205

# Running:

....E

Error:
ActiveModel::AttributeTest#test_attributes_do_not_equal_attributes_with_different_types:
NameError: uninitialized constant ActiveModel::AttributeTest::Type
    rails/activemodel/test/cases/attribute_test.rb:159:in `block in <class:AttributeTest>'

bin/test test/cases/attribute_test.rb:158
```

Added a missing require to fix this.

Subject: Relation merging should keep joining order

`joins_values.partition` will break joins values order. It should be
kept as user intended order.

Fixes #15488.

Subject: Add missing autoload `Type` (#31123)

Attribute modules (`Attribute`, `Attributes`, `AttributeSet`) uses
`Type`, but referencing `Type` before the modules still fail.

```
% ./bin/test -w test/cases/attribute_test.rb -n test_with_value_from_user_validates_the_value
Run options: -n test_with_value_from_user_validates_the_value --seed 31876

E

Error:
ActiveModel::AttributeTest#test_with_value_from_user_validates_the_value:
NameError: uninitialized constant ActiveModel::AttributeTest::Type
    /Users/kamipo/src/github.com/rails/rails/activemodel/test/cases/attribute_test.rb:233:in `block in <class:AttributeTest>'

bin/test test/cases/attribute_test.rb:232

Finished in 0.002985s, 335.0479 runs/s, 335.0479 assertions/s.
1 runs, 1 assertions, 0 failures, 1 errors, 0 skips
```

Probably we need more autoloading at least `Type`.

Subject: Deprecate encrypted secrets in favor of credentials.

This also removes the need for any of the setup code, so the
generator can be ripped out altogether.

Subject: Action Cable: run Redis tests against a default config without a
 password

Simplify our dev testing and CI story since we're also testing against
Redis for the Active Support cache store.

Directly test whether db, host, password, etc are passed through as
config instead of spinning up a Redis server with a password set on it.

Subject: Verify credentials format before saving

Currently, credentials does not check the format when saving. As a result,
incorrect data as yaml is also saved.
If credentials is used in config files., an error will occur in credential
yaml parsing before edit, and will not be able to edit it.

In order to prevent this, verify the format when saving.

Subject: Add new error class `StatementTimeout` which will be raised when
 statement timeout exceeded (#31129)

We are sometimes using The MAX_EXECUTION_TIME hint for MySQL depending
on the situation. It will prevent catastrophic performance down by wrong
performing queries.

The new error class `StatementTimeout` will make to be easier to handle
that case.

Subject: Make sidekiq and resque integration tests work in CI

Since 8f2490b, the integration test of sidekiq and resque is not working
in CI.
https://travis-ci.org/rails/rails/jobs/301276197#L2055
https://travis-ci.org/rails/rails/jobs/301276197#L2061

Because 8f2490b removed password from `redis-server`.
So must also remove passwords from these tests.

Subject: Properly cast input in `update_all`

The documentation claims that given values go through "normal AR type
casting and serialization", which to me implies
`serialize(cast(value))`, not just serialization. The docs were changed
to use this wording in #22492. The tests I cited in that PR (which is
the same test modified in this commit), is worded in a way that implies
it should be using `cast` as well.

It's possible that I originally meant "normal type casting" to imply
just the call to `serialize`, but given that `update_all(archived:
params['archived'])` seems to be pretty common, I'm inclined to make
this change as long as no tests are broken from it.

Subject: Built-in Redis cache store

* 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.

 ```
 
+### ActiveSupport::Cache::RedisCacheStore
+
+The Redis cache store takes advantage of Redis support for least-recently-used
+and least-frequently-used key eviction when it reaches max memory, allowing it
+to behave much like a Memcached cache server.
+
+Deployment note: Redis doesn't expire keys by default, so take care to use a
+dedicated Redis cache server. Don't fill up your persistent-Redis server with
+volatile cache data! Read the
+[Redis cache server setup guide](https://redis.io/topics/lru-cache) in detail.
+
+For an all-cache Redis server, set `maxmemory-policy` to an `allkeys` policy.
+Redis 4+ support least-frequently-used (`allkeys-lfu`) eviction, an excellent
+default choice. Redis 3 and earlier should use `allkeys-lru` for
+least-recently-used eviction.
+
+Set cache read and write timeouts relatively low. Regenerating a cached value
+is often faster than waiting more than a second to retrieve it. Both read and
+write timeouts default to 1 second, but may be set lower if your network is
+consistently low latency.
+
+Cache reads and writes never raise exceptions. They just return `nil` instead,
+behaving as if there was nothing in the cache. To gauge whether your cache is
+hitting exceptions, you may provide an `error_handler` to report to an
+exception gathering service. It must accept three keyword arguments: `method`,
+the cache store method that was originally called; `returning`, the value that
+was returned to the user, typically `nil`; and `exception`, the exception that
+was rescued.
+
+Putting it all together, a production Redis cache store may look something
+like this:
+
+```ruby
+cache_servers = %w[ "redis://cache-01:6379/0", "redis://cache-02:6379/0", … ],
+config.cache_store = :redis_cache_store, url: cache_servers,
+
+  connect_timeout: 30,  # Defaults to 20 seconds
+  read_timeout:    0.2, # Defaults to 1 second
+  write_timeout:   0.2, # Defaults to 1 second
+
+  error_handler: -> (method:, returning:, exception:) {
+    # Report errors to Sentry as warnings
+    Raven.capture_exception exception, level: 'warning",
+      tags: { method: method, returning: returning }
+  }
+```
+
 ### ActiveSupport::Cache::NullStore
 
 This cache store implementation is meant to be used only in development or test environments and it never stores anything. This can be very useful in development when you have code that interacts directly with `Rails.cache` but caching may interfere with being able to see the results of code changes. With this cache store, all `fetch` and `read` operations will result in a miss.

Subject: Add `environment` as dependency of `load_config` (#31135)

Currently the environment is not loaded in some db tasks.
Therefore, if use encrypted secrets values in `database.yml`,
`read_encrypted_secrets` will not be true, so the value can not be
used correctly.

To fix this, added `environment` as dependency of `load_config`.
It also removes explicit `environment` dependencies that are no longer
needed.

Fixes #30717

Subject: Cache: Enable compression by default for values > 1kB.

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.

     *Jeremy Daer*
 
+*   Cache: Enable compression by default for values > 1kB.
+
+    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.
+
+    *Jeremy Daer*
+
 *   Allow `Range#include?` on TWZ ranges
 
     In #11474 we prevented TWZ ranges being iterated over which matched

-* `:compress` - This option can be used to indicate that compression should be used in the cache. This can be useful for transferring large cache entries over a slow network.
+* `:compress` - Enabled by default. Compresses cache entries so more data can be stored in the same memory footprint, leading to fewer cache evictions and higher hit rates.
 
-* `:compress_threshold` - This option is used in conjunction with the `:compress` option to indicate a threshold under which cache entries should not be compressed. This defaults to 16 kilobytes.
+* `:compress_threshold` - Defaults to 1kB. Cache entries larger than this threshold, specified in bytes, are compressed.
 
 * `:expires_in` - This option sets an expiration time in seconds for the cache entry when it will be automatically removed from the cache.

Subject: Update configuring.md

It was brought to my attention that the Rails guide suggests using filenames to ensure code load order, so I thought I would suggest a better alternative.

 NOTE: You can use subfolders to organize your initializers if you like, because Rails will look into the whole file hierarchy from the initializers folder on down.
 
-TIP: If you have any ordering dependency in your initializers, you can control the load order through naming. Initializer files are loaded in alphabetical order by their path. For example, `01_critical.rb` will be loaded before `02_normal.rb`.
+TIP: While Rails supports numbering of initializer file names for load ordering purposes, a better technique is to place any code that need to load in a specific order within the same file. This reduces file name churn, makes dependencies more explicit, and can help surface new concepts within your application.

Subject: Handle `TZInfo::AmbiguousTime` errors

Make `ActiveSupport::TimeWithZone` match Ruby's handling of ambiguous
times by choosing the later period, e.g.

Ruby:
```
ENV["TZ"] = "Europe/Moscow"
Time.local(2014, 10, 26, 1, 0, 0)   # => 2014-10-26 01:00:00 +0300
```

Before:
```
>> "2014-10-26 01:00:00".in_time_zone("Moscow")
TZInfo::AmbiguousTime: 26/10/2014 01:00 is an ambiguous local time.
```

After:
```
>> "2014-10-26 01:00:00".in_time_zone("Moscow")
=> Sun, 26 Oct 2014 01:00:00 MSK +03:00
```

Fixes #17395.

+
+Threading and Code Execution in Rails
+=====================================
+
+After reading this guide, you will know:
+
+* What code Rails will automatically execute concurrently
+* How to integrate manual concurrency with Rails internals
+* How to wrap all application code
+* How to affect application reloading
+
+--------------------------------------------------------------------------------
+
+Automatic Concurrency
+---------------------
+
+Rails automatically allows various operations to be performed at the same time.
+
+When using a threaded web server, such as the default Puma, multiple HTTP
+requests will be served simultaneously, with each request provided its own
+controller instance.
+
+Threaded Active Job adapters, including the built-in Async, will likewise
+execute several jobs at the same time. Action Cable channels are managed this
+way too.
+
+These mechanisms all involve multiple threads, each managing work for a unique
+instance of some object (controller, job, channel), while sharing the global
+process space (such as classes and their configurations, and global variables).
+As long as your code doesn't modify any of those shared things, it can mostly
+ignore that other threads exist.
+
+The rest of this guide describes the mechanisms Rails uses to make it "mostly
+ignorable", and how extensions and applications with special needs can use them.
+
+Executor
+--------
+
+The Rails Executor separates application code from framework code: any time the
+framework invokes code you've written in your application, it will be wrapped by
+the Executor.
+
+The Executor consists of two callbacks: `to_run` and `to_complete`. The Run
+callback is called before the application code, and the Complete callback is
+called after.
+
+### Default callbacks
+
+In a default Rails application, the Executor callbacks are used to:
+
+* track which threads are in safe positions for autoloading and reloading
+* enable and disable the Active Record query cache
+* return acquired Active Record connections to the pool
+* constrain internal cache lifetimes
+
+### Wrapping application code
+
+If you're writing a library or component that will invoke application code, you
+should wrap it with a call to the executor:
+
+```ruby
+Rails.application.executor.wrap do
+  # call application code here
+end
+```
+
+TIP: If you repeatedly invoke application code from a long-running process, you
+may want to wrap using the Reloader instead.
+
+Each thread should be wrapped before it runs application code, so if your
+application manually delegates work to other threads, such as via `Thread.new`
+or Concurrent Ruby features that use thread pools, you should immediately wrap
+the block:
+
+```ruby
+Thread.new do
+  Rails.application.executor.wrap do
+    # your code here
+  end
+end
+```
+
+NOTE: Concurrent Ruby uses a `ThreadPoolExecutor`, which it sometimes configures
+with an `executor` option. Despite the name, it is unrelated.
+
+The Executor is safely re-entrant; if it is already active on the current
+thread, `wrap` is a no-op.
+
+If it's impractical to physically wrap the application code in a block (for
+example, the Rack API makes this problematic), you can also use the `run!` /
+`complete!` pair.
+
+### Concurrency
+
+The Executor will put the current thread into `running` mode in the Load
+Interlock. This operation will block temporarily if another thread is currently
+either autoloading a constant or unloading/reloading the application.
+
+Reloader
+--------
+
+Like the Executor, the Reloader also wraps application code. If the Executor is
+not already active on the current thread, the Reloader will invoke it for you,
+so you only need to call one. This also guarantees that everything the Reloader
+does, including all its callback invocations, occurs wrapped inside the
+Executor.
+
+```ruby
+Rails.application.reloader.wrap do
+  # call application code here
+end
+```
+
+### Callbacks
+
+Before entering the wrapped block, the Reloader will check whether the running
+application needs to be reloaded -- for example, because a model's source file has
+been modified. If it determines a reload is required, it will wait until it's
+safe, and then do so, before continuing. When the application is configured to
+always reload regardless of whether any changes are detected, the reload is
+instead performed at the end of the block.
+
+The Reloader also provides `to_run` and `to_complete` callbacks; they are
+invoked at the same points as those of the Executor, but only when the current
+execution has initiated an application reload. When no reload is deemed
+necessary, the Reloader will invoke the wrapped block with no other callbacks.
+
+### Class Unload
+
+The most significant part of the reloading process is the Class Unload, where
+all autoloaded classes are removed, ready to be loaded again. This will occur
+immediately before either the Run or Complete callback, depending on the
+`reload_classes_only_on_change` setting.
+
+Often, additional reloading actions need to be performed either just before or
+just after the Class Unload, so the Reloader also provides `before_class_unload`
+and `after_class_unload` callbacks.
+
+### Concurrency
+
+Only long-running "top level" processes should invoke the Reloader, because if
+it determines a reload is needed, it will block until all other threads have
+completed and left any Executor block.
+
+If this were to occur in a "child" thread, with a waiting parent inside the
+Executor, it would cause an unavoidable deadlock: the reload must occur before
+the child thread is executed, but it cannot be safely performed while the parent
+thread is mid-execution.
+
+Child threads should use the Executor instead.
+
+Load Interlock
+--------------
+
+The Load Interlock allows autoloading and reloading to be enabled in a
+multi-threaded runtime environment.
+
+When one thread is performing an autoload by evaluating the class definition
+from the appropriate file, it is important no other thread encounters a
+reference to the partially-defined constant.
+
+Similarly, it is only safe to perform an unload/reload when no application code
+is in mid-execution: after the reload, the `User` constant, for example, may
+point to a different class. Without this rule, a poorly-timed reload would mean
+`User.new.class == User`, or even `User == User`, could be false.
+
+Both of these constraints are addressed by the Load Interlock. It keeps track of
+which threads are currently running application code, loading a class, or
+unloading autoloaded constants.
+
+Only one thread may load or unload at a time, and to do either, it must wait
+until no other threads are running application code. If a thread is waiting to
+perform a load, it doesn't prevent other threads from loading (in fact, they'll
+cooperate, and each perform their queued load in turn, before all resuming
+running together).
+
+### `permit_concurrent_loads`
+
+The Executor automatically acquires a `running` lock for the duration of its
+block, and autoload knows when to upgrade to a `load` lock, and switch back to
+`running` again afterwards.
+
+Other blocking operations performed inside the Executor block (which includes
+all application code), however, can needlessly retain the `running` lock. If
+another thread encounters a constant it must autoload, this can cause a
+deadlock.
+
+For example, assuming `User` is not yet loaded, the following will deadlock:
+
+```ruby
+Rails.application.executor.wrap do
+  th = Thread.new do
+    Rails.application.executor.wrap do
+      User # inner thread waits here; it cannot load
+           # User while another thread is running
+    end
+  end
+
+  th.join # outer thread waits here, holding 'running' lock
+end
+```
+
+To prevent this deadlock, the outer thread can `permit_concurrent_loads`. By
+calling this method, the thread guarantees it will not dereference any
+possibly-autoloaded constant inside the supplied block. The safest way to meet
+that promise is to put it as close as possible to the blocking call only:
+
+```ruby
+Rails.application.executor.wrap do
+  th = Thread.new do
+    Rails.application.executor.wrap do
+      User # inner thread can acquire the load lock,
+           # load User, and continue
+    end
+  end
+
+  ActiveSupport::Dependencies.interlock.permit_concurrent_loads do
+    th.join # outer thread waits here, but has no lock
+  end
+end
+```
+
+Another example, using Concurrent Ruby:
+
+```ruby
+Rails.application.executor.wrap do
+  futures = 3.times.collect do |i|
+    Concurrent::Future.execute do
+      Rails.application.executor.wrap do
+        # do work here
+      end
+    end
+  end
+
+  values = ActiveSupport::Dependencies.interlock.permit_concurrent_loads do
+    futures.collect(&:value)
+  end
+end
+```
+
+
+### ActionDispatch::DebugLocks
+
+If your application is deadlocking and you think the Load Interlock may be
+involved, you can temporarily add the ActionDispatch::DebugLocks middleware to
+`config/application.rb`:
+
+```ruby
+config.middleware.insert_before Rack::Sendfile,
+                                  ActionDispatch::DebugLocks
+```
+
+If you then restart the application and re-trigger the deadlock condition,
+`/rails/locks` will show a summary of all threads currently known to the
+interlock, which lock level they are holding or awaiting, and their current
+backtrace.
+
+Generally a deadlock will be caused by the interlock conflicting with some other
+external lock or blocking I/O call. Once you find it, you can wrap it with
+`permit_concurrent_loads`.

+
+Framework Behavior
+------------------
+
+The Rails framework components use these tools to manage their own concurrency
+needs too.
+
+`ActionDispatch::Executor` and `ActionDispatch::Reloader` are Rack middlewares
+that wraps the request with a supplied Executor or Reloader, respectively. They
+are automatically included in the default application stack. The Reloader will
+ensure any arriving HTTP request is served with a freshly-loaded copy of the
+application if any code changes have occurred.
+
+Active Job also wraps its job executions with the Reloader, loading the latest
+code to execute each job as it comes off the queue.
+
+Action Cable uses the Executor instead: because a Cable connection is linked to
+a specific instance of a class, it's not possible to reload for every arriving
+websocket message. Only the message handler is wrapped, though; a long-running
+Cable connection does not prevent a reload that's triggered by a new incoming
+request or job. Instead, Action Cable uses the Reloader's `before_class_unload`
+callback to disconnect all its connections. When the client automatically
+reconnects, it will be speaking to the new version of the code.
+
+The above are the entry points to the framework, so they are responsible for
+ensuring their respective threads are protected, and deciding whether a reload
+is necessary. Other components only need to use the Executor when they spawn
+additional threads.
+
+### Configuration
+
+The Reloader only checks for file changes when `cache_classes` is false and
+`reload_classes_only_on_change` is true (which is the default in the
+`development` environment).
+
+When `cache_classes` is true (in `production`, by default), the Reloader is only
+a pass-through to the Executor.
+
+The Executor always has important work to do, like database connection
+management. When `cache_classes` and `eager_load` are both true (`production`),
+no autoloading or class reloading will occur, so it does not need the Load
+Interlock. If either of those are false (`development`), then the Executor will
+use the Load Interlock to ensure constants are only loaded when it is safe.

Subject: Avoid creating extra `relation` and `build_arel` in `_create_record`
 and `_update_record` (#29999)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently `_create_record` and `_update_record` in `Persistence` are
creating extra `unscoped` and calling `build_arel` in the relation. But
`compile_insert` and `compile_update` can be done without those
expensive operation for `SelectManager` creation. So I moved the
implementation to `Persistence` to avoid creating extra relation and
refactored to avoid calling `build_arel`.

https://gist.github.com/kamipo/8ed73d760112cfa5f6263c9413633419

Before:

```
Warming up --------------------------------------
      _update_record   150.000  i/100ms
Calculating -------------------------------------
      _update_record      1.548k (±12.3%) i/s -      7.650k in   5.042603s
```

After:

```
Warming up --------------------------------------
      _update_record   201.000  i/100ms
Calculating -------------------------------------
      _update_record      2.002k (±12.8%) i/s -      9.849k in   5.027681s
```

30% faster for STI classes.

Subject: Deprecate an `after_bundle` callback in Rails plugin templates

Since fbd1e98cf983572ca9884f17f933ffe92833632a, Rails plugin does not
run `bundle install` when generating.
Therefore, `after_bundle` callback is not actually executed after `bundle`.

Since there is a difference between the name and the actual behavior,
I think that should be remove.

+If you want to use a headless browser, you could use Headless Chrome by adding `headless_chrome` in the `:using` argument.
+
+```ruby
+require "test_helper"
+
+class ApplicationSystemTestCase < ActionDispatch::SystemTestCase

 If your Capybara configuration requires more setup than provided by Rails, this
 additional configuration could be added into the `application_system_test_case.rb`

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These extra `spawn` are called via `klass.all` and `klass.all` is called
everywhere in the internal. Avoiding the extra `spawn` makes` klass.all`
30% faster for STI classes.

Subject: Fix direct uploads to local service
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Disable CSRF protection for ActiveStorage::DiskController#update. The local disk service is intended to imitate a third-party service like S3 or GCS, so we don't care where direct uploads originate: they’re authorized by signed tokens.

Closes #30290.

https://github.com/jruby/activerecord-jdbc-adapter ActiveRecord JDBC Adapter is actively developed
and it supports Rails 5.1 now. This pull request addresses one of the failure when running
ActiveRecord unit tests with ActiveRecord JDBC Adapter.

As of right now, ActiveRecord JDBC Adapter supports Rails 5.1, not master branch
then this test only can run on `5-1-stable` branch. But I have opened this pull request to `master` branch
since this type cast should be going to work in the future versions of ActiveRecord JDBC Adapter .

Particularly, the bulleted list was getting formatted as a code block because of the extra level of indentation.  Pulling it back to the left makes it render properly as a list instead.

The cause is writing io from different thread at the same time.

`connection.process` sends handshake message from [StreamEventLoop's thread][] whereas
`connection.handle_open` sends welcome message from current thread.

Subject: Compare the actual string after comparing the HMAC proccessed strings

Even that collisions are unlikely we need to make sure the two strings
are equal.

Timing is not important in this case because this only runs after the
comparison between the SHA256 digested strings returns true.

Subject: Change `form_with` to generates ids by default

When `form_with` was introduced we disabled the automatic
generation of ids that was enabled in `form_for`. This usually
is not an good idea since labels don't work when the input
doesn't have an id and it made harder to test with Capybara.

You can still disable the automatic generation of ids setting
`config.action_view.form_with_generates_ids` to `false.`

Subject: Remove field ids from scaffold form

This was added with 27f103fc7e3260efe0b8dde66bf5354f2202ee32 for link labels and fields.
However, `form_with` changed to generates ids by default with d3893ec38ec61282c2598b01a298124356d6b35a.
So I think that adding an explicit ids is unnecessary.

This PR philosophically conflicts with #30800 and Matthew thinks we

Subject: Rename `TransactionTimeout` to more descriptive `LockWaitTimeout`
 (#31223)

Since #31129, new error class `StatementTimeout` has been added.
`TransactionTimeout` is caused by the timeout shorter than
`StatementTimeout`, but its name is too generic. I think that it should
be a name that understands the difference with `StatementTimeout`.

Subject: Add new error class `QueryCanceled` which will be raised when
 canceling statement due to user request (#31235)

This changes `StatementTimeout` to `QueryCanceled` for PostgreSQL.

In MySQL, errno 1317 (`ER_QUERY_INTERRUPTED`) is only used when the
query is manually cancelled.

But in PostgreSQL, `QUERY_CANCELED` error code (57014) which is used
`StatementTimeout` is also used when the both case. And, we can not tell
which reason happened.

So I decided to introduce new error class `QueryCanceled` closer to the
error code name.

Subject: Inverse instance should not be reloaded during autosave if called in
 validation

Record saved in save_has_one_association already make call to association.loaded! via record's before_save callback of save_belongs_to_association,
 but this will reload object if accessed in record's validation.

Subject: Use Puma 3.11 in newly generated applications

In order to use early hints, need to use Puma 3.11.0 or higher.
So, I think that should specify that version in newly generated applications.

Ref: https://github.com/puma/puma/commit/f6f3892f4d82638fb7a2a57d993641b1486ee88a

Subject: Enable `Style/DefWithParentheses` rubocop rule

The def with blank `()` was newly added in #31176, but we have not used
the blank `()` style in most part of our code base.
So I've enabled `Style/DefWithParentheses` to prevent to newly added the
code.

+*   Add DSL for configuring Content-Security-Policy header
+
+    The DSL allows you to configure a global Content-Security-Policy
+    header and then override within a controller. For more information
+    about the Content-Security-Policy header see MDN:
+
+    https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy
+    
+    Example global policy:
+    
+        # config/initializers/content_security_policy.rb
+        Rails.application.config.content_security_policy do
+          p.default_src :self, :https
+          p.font_src    :self, :https, :data
+          p.img_src     :self, :https, :data
+          p.object_src  :none
+          p.script_src  :self, :https
+          p.style_src   :self, :https, :unsafe_inline
+        end
+    
+    Example controller overrides:
+    
+        # Override policy inline
+        class PostsController < ApplicationController
+          content_security_policy do |p|
+            p.upgrade_insecure_requests true
+          end
+        end
+
+        # Using literal values
+        class PostsController < ApplicationController
+          content_security_policy do |p|
+            p.base_uri "https://www.example.com"
+          end
+        end
+
+        # Using mixed static and dynamic values
+        class PostsController < ApplicationController
+          content_security_policy do |p|
+            p.base_uri :self, -> { "https://#{current_user.domain}.example.com" }
+          end
+        end
+        
+    Allows you to also only report content violations for migrating
+    legacy content using the `content_security_policy_report_only`
+    configuration attribute, e.g;
+    
+        # config/initializers/content_security_policy.rb
+        Rails.application.config.content_security_policy_report_only = true
+

+        class PostsController < ApplicationController
+          self.content_security_policy_report_only = true

+    reasons since the header is calculated at runtime.

+
+Ruby on Rails 5.2 Release Notes
+===============================
+
+Highlights in Rails 5.2:
+
+* Active Storage
+* Redis Cache Store
+* HTTP/2 Early hints support
+* Credentials
+
+These release notes cover only the major changes. To learn about various bug
+fixes and changes, please refer to the change logs or check out the [list of
+commits](https://github.com/rails/rails/commits/5-2-stable) in the main Rails
+repository on GitHub.
+
+--------------------------------------------------------------------------------
+
+Upgrading to Rails 5.2
+----------------------
+
+If you're upgrading an existing application, it's a great idea to have good test
+coverage before going in. You should also first upgrade to Rails 5.1 in case you
+haven't and make sure your application still runs as expected before attempting
+an update to Rails 5.2.
+
+
+Major Features
+--------------
+
+### Active Storage
+
+[README](https://github.com/rails/rails/blob/d3893ec38ec61282c2598b01a298124356d6b35a/activestorage/README.md)
+
+### Redis Cache Store

Subject: Drop mysql2 version less than 0.4.3 to guarantee fork safety (#31244)

Since #31173, mysql2 adapter depends on `automatic_close` which is
introduced since mysql2 0.4.3. So the adapter with the mysql2 version
before doesn't work with fork now.

```
% ARCONN=mysql2 be ruby -w -Itest test/cases/connection_adapters/connection_handler_test.rb -n test_forked_child_doesnt_mangle_parent_connection
Using mysql2
Run options: -n test_forked_child_doesnt_mangle_parent_connection --seed 19988

/Users/kamipo/src/github.com/rails/rails/activerecord/lib/active_record/connection_adapters/mysql2_adapter.rb:108:in `discard!': undefined method `automatic_close=' for #<Mysql2::Client:0x00007fedaa91dfd0> (NoMethodError)
```

This drops mysql2 version less than 0.4.3 to guarantee fork safety.

Subject: Change how `AttributeSet::Builder` receives its defaults

There are two concerns which are both being combined into one here, but
both have the same goal. There are certain attributes which we want to
always consider initialized. Previously, they were handled separately.
The primary key (which is assumed to be backed by a database column)
needs to be initialized, because there is a ton of code in Active Record
that assumes `foo.id` will never raise. Additionally, we want attributes
which aren't backed by a database column to always be initialized, since
we would never receive a database value for them.

Ultimately these two concerns can be combined into one. The old
implementation hid a lot of inherent complexity, and is hard to optimize
from the outside. We can simplify things significantly by just passing
in a hash.

This has slightly different semantics from the old behavior, in that
`Foo.select(:bar).first.id` will return the default value for the
primary key, rather than `nil` unconditionally -- however, the default
value is always `nil` in practice.

Subject: Update cookie_store_test to use encrypted cookies

This now modernizes these tests to use encrypted cookies instead of
using secret_token HMACs. This commit also adds a tests to ensure
session cookies with :expires_after set are invalidated and no longer
accepted when the time has elapsed.

 What Does a Controller Do?
 --------------------------
 
-Action Controller is the C in MVC. After the router has determined which controller to use for a request, the controller is responsible for making sense of the request and producing the appropriate output. Luckily, Action Controller does most of the groundwork for you and uses smart conventions to make this as straightforward as possible.
+Action Controller is the C in [MVC](https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller). After the router has determined which controller to use for a request, the controller is responsible for making sense of the request, and producing the appropriate output. Luckily, Action Controller does most of the groundwork for you and uses smart conventions to make this as straightforward as possible.
 
 For most conventional [RESTful](https://en.wikipedia.org/wiki/Representational_state_transfer) applications, the controller will receive the request (this is invisible to you as the developer), fetch or save data from a model and use a view to create HTML output. If your controller needs to do things a little differently, that's not a problem, this is just the most common way for a controller to work.

Subject: Prevent scope named same as a ActiveRecord::Relation instance method.
 Due to inconsistent behavior when chaining scopes and one scope named after a
 Relation method

Validation code added in 2 places:

- scope, to prevent problematic scope names.
- enum, cause it tries to auto define scope.

Subject: Refactor Date/Time next_occurring and prev_occurring
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These methods were originally added in https://github.com/rails/rails/pull/26600

This includes a couple of refactors to make these methods behave more similarly to other Date/Time extensions added by Active Support:

1. Use `advance` instead of `since` and `ago` to time-travel — this is particularly important to keep the returned instance’s class matching `self`.  Before this change:

    today = Date.today                     # => Tue, 28 Nov 2017
    today.class                            # => Date
    today.next_occurring(:wednesday)       # => Wed, 29 Nov 2017 00:00:00 UTC +00:00
    today.next_occurring(:wednesday).class # => ActiveSupport::TimeWithZone

  After this change, a Date (or Time, or DateTime) instance is properly returned (just like is shown in the new docs).  This is generally how everything else in DateAndTime::Calculations works.

2. Move the tests from the DateTime tests to the DateAndTimeBehavior tests.  The latter location is mixed in to the core_ext tests for _all_ of Date, Time, and DateTime to test the behavior across all of the classes.  The previous location is for testing core_ext functionality added specifically just to DateTime.

3. Better docs!

Subject: Use `credentials` instead of `keyfile` in GCS sevice

The `keyfile` was renamed to `credentials` in `google-cloud-storage` 1.8.0.
https://github.com/GoogleCloudPlatform/google-cloud-ruby/blob/master/google-cloud-storage/CHANGELOG.md#180--2017-11-14

Although `keyfile` can still be used, but it looks like deprecate.
https://github.com/GoogleCloudPlatform/google-cloud-ruby/blob/ddf7b2a856d676316525eb581c1a4cc83ca6097b/google-cloud-storage/lib/google/cloud/storage.rb#L589...L590

Therefore, I think that should use `credentials` in newly generated
applications.

Subject: Keep current Code Climate behavior before upgrade

If you merge these changes now (*before Monday, December 4th*), Code Climate will run the same analysis on Rails as it always has on your pull requests.

*If you do not merge these changes*, when Code Climate migrates Rails to our new analysis, Code Climate will continue to run Rubocop, but it will ALSO run Code Climate's new maintainability checks (https://codeclimate.com/blog/10-point-technical-debt-assessment).

You may want this ... you may not.

Just want to make sure you knew the quick option to disable them if it's a problem!

Subject: Add support for PostgreSQL operator classes to add_index

Add support for specifying non-default operator classes in PostgreSQL
indexes. An example CREATE INDEX query that becomes possible is:

    CREATE INDEX users_name ON users USING gist (name gist_trgm_ops);

Previously it was possible to specify the `gist` index but not the
custom operator class. The `add_index` call for the above query is:

    add_index :users, :name, using: :gist, opclasses: {name: :gist_trgm_ops}

Subject: Maintain raising `RecordNotFound` for class level `update` and`
 destroy`

In 35836019, class level `update` and `destroy` suppressed
`RecordNotFound` to ensure returning affected objects. But
`RecordNotFound` is a common exception caught by a `rescue_from`
handler. So changing the behavior when a typical `params[:id]` is passed
has a compatibility problem. The previous behavior should not be
changed.

Fixes #31301.

Subject: Fix typo in test error message

With the current code, a failing test shows this error, which is missing
the number of times called and has two periods at the end.

```
/railties$ be ruby -Itest test/generators/app_generator_test.rb -n test_active_storage_install

Failure:
AppGeneratorTest#test_active_storage_install [test/generators/app_generator_test.rb:313]:
active_storage:install expected to be called once, but was called  times..
Expected: 1
  Actual: 2
```

After the fix, the error message looks correct:

```
/railties$ be ruby -Itest test/generators/app_generator_test.rb -n test_active_storage_install

Failure:
AppGeneratorTest#test_active_storage_install [test/generators/app_generator_test.rb:313]:
active_storage:install expected to be called once, but was called 2 times.
Expected: 1
  Actual: 2

Subject: Emulate JSON types for SQLite3 adapter (#29664)

Actually SQLite3 doesn't have JSON storage class (so it is stored as a
TEXT like Date and Time). But emulating JSON types is convinient for
making database agnostic migrations.

Subject: SQLite3 valid integer value should be 8 bytes (64-bit signed integer)
 (#28379)

This is a regression since Rails 4.2.

SQLite3 integer is stored in 1, 2, 3, 4, 6, or 8 bytes depending on the
magnitude of the value. Assuming default valid value as 4 bytes caused
that actual valid value in INTEGER storage class cannot be stored and
existing value cannot be found.

https://www.sqlite.org/datatype3.html

We should allow valid value in INTEGER storage class in SQLite3 to fix
the regression.

Fixes #22594.

`get_all_versions` doesn't use passed `connection`. So it should be

Subject: Fix example code in ActiveJob::Core [ci skip]

1) It seems that it raise error on example code in `ActiveJob::Core`.

Before:

```ruby
class DeliverWebhookJob < ActiveJob::Base
  def serialize
    super.merge('attempt_number' => (@attempt_number || 0) + 1)
  end

  def deserialize(job_data)
    super
    @attempt_number = job_data['attempt_number']
  end

  rescue_from(Timeout::Error) do |exception|
    raise exception if @attempt_number > 5
    retry_job(wait: 10)
  end

  def perform
    raise Timeout::Error
  end
end
```

Then it run `DeliverWebhookJob.perform_now` in `rails console`. And raise error:

NoMethodError: undefined method `>' for nil:NilClass
from /app/jobs/deliver_webhook_job.rb:12:in `block in <class:DeliverWebhookJob>'

So I thought it's necessary to fix it.

After:

```ruby
class DeliverWebhookJob < ActiveJob::Base
  attr_writer :attempt_number

  def attempt_number
    @attempt_number ||= 0
  end

  def serialize
    super.merge('attempt_number' => attempt_number + 1)
  end

  def deserialize(job_data)
    super
    self.attempt_number = job_data['attempt_number']
  end

  rescue_from(Timeout::Error) do |exception|
    raise exception if attempt_number > 5
    retry_job(wait: 10)
  end

  def perform
    raise Timeout::Error
  end
end
```

Then it run `DeliverWebhookJob.perform_now` in `rails console`. And it does'nt raise error NoMethodError.

2) Use `Timeout::Error` instead of `TimeoutError` (`TimeoutError` is deprecated).

Subject: Fix sqlite migrations with custom primary keys

Previously, if a record was created with a custom primary key, that
table could not be migrated using sqlite. While attempting to copy the
table, the type of the primary key was ignored.

Once that was corrected, copying the indexes would fail because custom
primary keys are autoindexed by sqlite by default.

To correct that, this skips copying the index if the index name begins
with "sqlite_". This is a reserved word that indicates that the
index is an internal schema object. SQLite prohibits applications from
creating objects whose names begin with "sqlite_", so this string should
be safe to use as a check.

Subject: Fix Rails environment when running tests with Ruby

I frequently run tests with `ruby`, not with a runner like `rake` or
`rails`.  When running the test with just `ruby` the `RAILS_ENV`
environment variable did not get set to "test", and this would cause the
tests to fail (and even mutate the development database!)

This commit adds integration tests for running tests with just `ruby`
and ensures the environment gets defaulted to "test".  I also added a
test to ensure that passing an environment to `-e` actually works (and
fixed that case too).

An interesting / annoying thing is that Minitest picks up it's plugins
by asking RubyGems for a list of files:

  https://github.com/seattlerb/minitest/blob/ca6a71ca901016db09a5ad466b4adea4b52a504a/lib/minitest.rb#L92-L100

This means that RubyGems needs to somehow know about the file before it
can return it to Minitest.  Since we are not packaging Rails as a Gem
before running the integration tests on it (duh, why would you do
that?), RubyGems doesn't know about the file, so it can't tell Minitest,
so Minitest doesn't automatically require it.  This means I had to
manually require and insert the plugin in our integration test.  I've
left comments about that in the test as well.

Ugh.

Subject: [ci skip] Make Todo classes inherit ApplicationRecord

Example codes that use `has_many` or `before_create` in `Module::Concerning` look like active record models.
So I've made them inherit `ApplicationRecord`.

Subject: Fix `scope_for_create` to do not lose polymorphic associations

This regression was caused at 213796fb due to polymorphic predicates are
combined by `Arel::Nodes::And`. But I'd like to keep that combined
because it would help inverting polymorphic predicates correctly
(e9ba12f7), and we can collect equality nodes regardless of combined by
`Arel::Nodes::And` (`a AND (b AND c) AND d` == `a AND b AND c AND d`).
This change fixes the regression to collect equality nodes in
`Arel::Nodes::And` as well.

Fixes #31338.

Subject: SQLite: Fix `copy_table` with composite primary keys

`connection.primary_key` also return composite primary keys, so
`from_primary_key_column` may not be found even if `from_primary_key` is
presented.

```
% ARCONN=sqlite3 be ruby -w -Itest
test/cases/adapters/sqlite3/sqlite3_adapter_test.rb -n
test_copy_table_with_composite_primary_keys
Using sqlite3
Run options: -n test_copy_table_with_composite_primary_keys --seed 19041

# Running:

E

Error:
ActiveRecord::ConnectionAdapters::SQLite3AdapterTest#test_copy_table_with_composite_primary_keys:
NoMethodError: undefined method `type' for nil:NilClass
    /path/to/rails/activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb:411:in
    `block in copy_table'
```

This change fixes `copy_table` to do not lose composite primary keys.

Subject: Add failing test for wrong database connection

When tests are run with just `ruby`, the RAILS_ENV is set to
`development` too early, and we connect to the development database
rather than the test database.

Subject: Set the Rails environment from an environment variable

Option parsing happens too late to have any impact on the Rails
environment.  Rails accesses the environment name and memoizes it too
early in the boot process for a commandline option to have any impact on
the database connection, so we'll change this test to set the
environment from an environment variable (and ensure it still works when
running tests with `ruby`)
