We're already running Performance/RegexpMatch cop, but it seems like the cop is not always =~ justice

In case a negative position is provided that exceeds the size of the
string, we're relying on -1 returned from max to get 0 length by + 1
and let [] with a 0 length returning "" for us.
E.g. "hello".to(-7), where -7 + 5 size = -2. That's
lower than -1, so we use -1 instead and + 1 would turn it into 0.
Instead allow outer bounds access and always return "".

GB18030 is Unicode compatible and covers all Unicode code points so we can temporarily convert GB18030 strings to UTF-8 to perform the transliteration. After transliterating we want to convert back to GB18030.
In all cases of transcoding, we replace invalid or undefined characters with the default replacement character ("?"). This is in line with the behavior of tidy_bytes which is used on the UTF-8 string before transliterating.

US-ASCII is a subset of UTF-8 so we can temporarily convert US-ASCII strings to UTF-8 to perform the transliteration. After we've converted characters to ASCII representations, we can set the encoding back to US-ASCII to return the same encoding we accepted.

`Messages::Rotator` has `@on_rotation` not `@rotation`.

Merge payload for EventObject subscribers
|

When instrumenting a block of code like:
```ruby
ActiveSupport::Notifications.instrument("process_action.action_controller", raw_paylaod) do |payload|
payload[:view_runtime] = render_view
end
```
If we use an evented subscriber like so:
``` ruby
ActiveSupport::Notifications.subscribe("process_action.action_controller", raw_payload) do |event|
assert event.payload[:view_runtime]
end
```
The code breaks because the underlying EventObject's payload does not have the
`:view_runtime` key added during instrumentation.
This is because the `EventedObject` subscriber calls the `finish` method with the
`payload` of the event at the time it was pushed into the stack, before the
block executes, but we want to call `finish` with the `payload` after the
instrument block executes this way if the `payload` was modified during the block
we have access to it. This is consistent with the other types of subscribers
who don't have this bug.

Add compact_blank shortcut for reject(&:blank?)

I frequently find myself having to .compact but for blank. which means
on an array reject(&:blank?) (this is fine), or,
on a hash `.reject { |_k, v| v.blank? }` which is slightly more
frustrating and i usually write it as .reject(&:blank?) first and am
confused when it's trying to check if the keys are blank.
I've added the analagous .compact_blank! where there's a reject! to
build on (there's also a reject! in Set, but there's no other core_ext
touching Set so i've left that alone)

- This class is used to rotate a previously determined value to a new
one before making the comparions.
We use this at Shopify to rotate Basic Auth crendials but I can
imagine other use cases.
The implementation uses the same `Messages::Rotator` module than
the MessageEncryptor/MessageVerifier class so it works exactly the
same way.
You can use it as follow:
```ruby
rotator = ActiveSupport::SecureCompareRotator.new('new_production_value')
rotator.rotate('previous_production_value')
rotator.secure_compare!('previous_production_value')
```

Add support for Proc based parameter filtering on arrays of values

Based on the way parameters are currently processed, a parameter value of type Hash is recursively processed. For a value of type Array however, the current behavior is to simply return the original array, with no filtering. It is not clear what the expected behavior should be. But, doing nothing seems incorrect, since it bypasses custom Proc based parameter filtering all together for arrays of values. This change introduces a failing test in preparation to add logic that proposes one possible option for the expected behavior with Array values.

Exclude missing marshal_dump and _dump methods from being delegated to
an object's delegation target via the delegate_missing_to extension.
This avoids unintentionally adding instance variables to an object
during marshallization, should the delegation target be a method which
would otherwise add them.
In current versions of Ruby, a bug exists in the way objects are
marshalled, allowing for instance variables to be added or removed
during marshallization (see https://bugs.ruby-lang.org/issues/15968).
This results in a corrupted serialized byte stream, causing an object's
instance variables to "leak" into subsequent serialized objects during
demarshallization.
In Rails, this behavior may be triggered when marshalling an object that
uses the delegate_missing_to extension, if the delegation target is a
method which adds or removes instance variables to an object being
marshalled - when calling Marshal.dump(object), Ruby's built in behavior
will check whether the object responds to :marshal_dump or :_dump, which
in turn triggers the delegation target method in the
responds_to_missing? function defined in
activesupport/lib/active_support/core_ext/module/delegation.rb
While future versions of Ruby will resolve this bug by raising a
RuntimeError, the underlying cause of this error may not be readily
apparent when encountered by Rails developers. By excluding marshal_dump
and _dump from being delegated to an object's target, this commit
eliminates a potential cause of unexpected behavior and/or
RuntimeErrors.

`ActiveSupport::Inflector.transliterate`"
|
| | | | |
| | | | |
| | | | |
| | | | |
| | | | |
| | | | | |
It's noted in #34062 that String#parameterize will raise an `Encoding::CompatibilityError` if the string is not UTF-8 encoded. The error is raised as a result of passing the string to `.unicode_normalize`.
This PR raises a higher level `ArgumentError` if the provided string is not UTF-8 and updates documentation to note the encoding requirement.

Fix problem with accessing deprecated constant proxy's subclass

This commit fixes #36313.
After #32065 moved `SourceAnnotationExtractor` into `Rails` module, it
broke the ability to access `SourceAnnotationExtractor::Annotate`
directly as user would get this error:
TypeError: Rails::SourceAnnotationExtractor is not a class/module
This commit fixes the issue by making `DeprecatedConstantProxy` to
inherit from `Module` and then defines `method_missing` and
`const_missing` to retain the previous functionality.
Thank you Matthew Draper for the idea of how to fix the issue!

Return a copy of the cache entry when local_cache exists:

| | | | | |

| | | | | |
| | | | | |
| | | | | | |
- When the local cache exists (during the request lifecycle), the
entry returned from the LocalStore is passed as a reference which
means mutable object can accidentaly get modified.
This behaviour seems unnecessarily unsafe and is prone to
issues like it happened in our application.
This patch dup the `Entry` returned from the cache and dup it's
internal value.

We sometimes say "✂️ newline after `private`" in a code review (e.g.
https://github.com/rails/rails/pull/18546#discussion_r23188776,
https://github.com/rails/rails/pull/34832#discussion_r244847195).
Now `Layout/EmptyLinesAroundAccessModifier` cop have new enforced style
`EnforcedStyle: only_before` (https://github.com/rubocop-hq/rubocop/pull/7059).
That cop and enforced style will reduce the our code review cost.

- Use case:
I'm writing a wrapper around MessageEncryptor to make things easier
to rotate a secret in our app.
It works something like
```ruby
crypt = RotatableSecret.new(['old_secret', 'new_secret'])
crypt.decrypt_and_verify(message)
```
I'd like the caller to not have to care about passing the
`on_rotation` option and have the wrapper deal with it when
instantiating the MessageEncryptor object.
Also, almost all of the time the on_rotation should be the same when
rotating a secret (logging something or StatsD event) so I think
it's not worth having to repeat ourselves each time we decrypt a message.

And also, add new `monotonic` argument to the last of the method
signature rather than the first.

Fix EventedFileUpdateChecker through a symlink

On MacOS, Dir.tmpdir gives me a folder inside "/var/folders/". However,
/var is a symlink to /private/var.
Previously, the nonexistent directory test would fail because it was
initialized with /var/folders/... but the filenames from listen would be
the realpaths.
This commit normalizes the dirs by calling realpath on them if they
exist. This is done on boot!, so it will work with newly directories
through the symlink.

| | |
| | |
| | |
| | | |
The common include of this test creates a tmpdir, we should use that for
consistency.

Rails 4 -> Rails 5 introduced a #to_hash call in
HashWithIndifferentAccess#initialize to guarantee access to
the #default and #default_proc methods. This can be a very
expensive operation for very large HashWithIndifferentAccess
objects. This commit bypasses this #to_hash call if it is
already a Hash.

The change to monotonic times causes failures for applications
where the subscribed block is expecting Time objects as described
in this issue: https://github.com/rails/rails/issues/36145
The original PR (https://github.com/rails/rails/pull/35984) was
concerned with errors on the cpu_time. Test was edited to reflect
changes to initializer using 0 values instead of nil

Refactor `ActiveSupport::Deprecation.deprecate_methods` not to expose internal methods

internal methods
In #33325, `deprecate_methods` is replaced from `prepend` to completely
emurated `alias_method_chain`, it exposed two internal methods
`xxx_with_deprecation` and `xxx_without_deprecation`.
After that, #34648 restored the `prepend` implementation, which doesn't
expose any internal methods, so we no longer be able to ensure to always
expose that internal methods.
As I said at https://github.com/rails/rails/pull/33325#issuecomment-409016725,
I think that internal methods exposed is not a specification but a
limitation when using `alias_method_chain`, there is no longer a reason
to follow that limitation.

Actionable errors let's you dispatch actions from Rails' error pages. This
can help you save time if you have a clear action for the resolution of
common development errors.
The de-facto example are pending migrations. Every time pending migrations
are found, a middleware raises an error. With actionable errors, you can
run the migrations right from the error page. Other examples include Rails
plugins that need to run a rake task to setup themselves. They can now
raise actionable errors to run the setup straight from the error pages.
Here is how to define an actionable error:
```ruby
class PendingMigrationError < MigrationError #:nodoc:
include ActiveSupport::ActionableError
action "Run pending migrations" do
ActiveRecord::Tasks::DatabaseTasks.migrate
end
end
```
To make an error actionable, include the `ActiveSupport::ActionableError`
module and invoke the `action` class macro to define the action. An action
needs a name and a procedure to execute. The name is shown as the name of a
button on the error pages. Once clicked, it will invoke the given
procedure.
