Added the ability to initialize `thread_mattr_*` methods with default
values like so:
``` ruby
class MyClass
thread_attr_reader :foo, default: :foo
thread_attr_writer :bar, default: :bar
thread_attr_accessor: baz do
"baz"
end
end
```
This is consistent with the api exposed by `mattr_accessor`.

Removes unnecessary conditional and method call for significant
performance improvement. As a side effect, this fixes an unexpected
behavior where passing a limit of 0 would return a frozen string.
This also implements the Rails 6.1 intended behavior with regards to
negative limits, and removes the previous deprecation warnings.
String#first Comparison:
new: 3056515.0 i/s
old: 1943310.2 i/s - 1.57x slower
String#last Comparison:
new: 2691919.0 i/s
old: 1924256.6 i/s - 1.40x slower
(Note: "old" benchmarks have deprecation warnings commented out, for a
more fair comparison.)

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 "".

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)

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.
Fixes #36522

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.

* Add test asserting truncate returns unfrozen string
* Ensure strings returned from truncate are not frozen
This fixes an issue where strings too short to be truncated were
returned unfrozen, where as long-enough strings were returned
frozen. Now retuned strings will not be frozen whether or not
the string returned was shortened.
* Update changelog w/ new truncate behavior description

```
After:
```ruby

```

support for Range arguments, with similar handling of this case.

In #10634 the behavior of Time#advance was changed to maintain a
proleptic gregorian calendar for dates before calendar reform. However
it didn't full address dates a long time before calendar reform and
they gradually drift away from the proleptic calendar the further you
go back in time. Fix this by always converting the date to gregorian
before calling advance which sets the reform date to -infinity.

Enable `Style/RedundantBegin` cop to avoid newly adding redundant begin block
|
| | |
| |
| |
| |
| |
| |
| |
| |
| |

Currently we sometimes find a redundant begin block in code review
(e.g. https://github.com/rails/rails/pull/33604#discussion_r209784205).
I'd like to enable `Style/RedundantBegin` cop to avoid that, since
rescue/else/ensure are allowed inside do/end blocks in Ruby 2.5
(https://bugs.ruby-lang.org/issues/12906), so we'd probably meets with
that situation than before.

- Adding a Float as a duration to a datetime would result in the Float
being rounded. Doing something like would have no effect because the
0.45 seconds would be rounded to 0 second.
```ruby
time = DateTime.parse("2018-1-1")
time += 0.45.seconds
```
This behavior was intentionally added a very long time ago, the
reason was because Ruby 1.8 was using `Integer#gcd` in the
constructor of Rational which didn't accept a float value.
That's no longer the case and doing `Rational(0.45, 86400)` would
now perfectly work fine.
- Fixes #34008

Since Rails 6.0 will support Ruby 2.4.1 or higher
`# frozen_string_literal: true` magic comment is enough to make string object frozen.
This magic comment is enabled by `Style/FrozenStringLiteralComment` cop.
* Exclude these files not to auto correct false positive `Regexp#freeze`
- 'actionpack/lib/action_dispatch/journey/router/utils.rb'
- 'activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb'
It has been fixed by https://github.com/rubocop-hq/rubocop/pull/6333
Once the newer version of RuboCop released and available at Code Climate these exclude entries should be removed.
* Replace `String#freeze` with `String#-@` manually if explicit frozen string objects are required
- 'actionpack/test/controller/test_case_test.rb'

The method removes and returns the elements for which the block returns a true value.
If no block is given, an Enumerator is returned instead.
```
numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
odd_numbers = numbers.extract! { |number| number.odd? } # => [1, 3, 5, 7, 9]

- There was an issue inside controller tests where order params were not respected, the reason
was because we were calling `Hash#to_query` which sorts the results lexicographically.
1e4e1b62 fixed that issue by not using `to_query` but instead a utility function provided by rack.
- However with the fix came another issue where it's now no longer possible to do this
```
post :foo, params: { user: User.first }
# Prior to the patch the controller will receive { "user" => "1" }
# Whereas now you get { "user": "#<User: ...>" }
```
The fix in this PR is to modify `Hash#to_query` to sort only when it
doesn't contain an array structure that looks something like "bar[]"

When multiplying or dividing a duration by a scalar, it's tempting to
operate directly on the duration's value in seconds and recompute the
parts from the result. However this loses information, as there are
multiple combinations of parts that map to any given number of seconds
(e.g. `2.weeks` or `336.hours`). This is especially problematic when
dealing with durations on the scale of months or years, as converting an
exact number of seconds to one of those intervals and then using the
resulting duration to modify a date will give the wrong result.
