In the following situation:
```ruby
class Bar
end
module Baz
end
class Foo
prepend Baz
end
class Foo::Bar
end
```
Running `Inflector.constantize('Foo::Bar')` would blow up with a NameError.
What is happening is that `constatize` was written before the introduction
of prepend, and wrongly assume that `klass.ancestors.first == klass`.
So it uses `klass.ancestors.inject` without arguments, as a result
a prepended module is used in place of the actual class.
This fixes the following warning.
```

Ref: 65e27c8b13
This behavior changed in Ruby starting with 2.3.0, as a result of
https://bugs.ruby-lang.org/issues/11360. This results in a change in
behavior of these methods which is likely undesirable.
Fixes#27238
The issue affects MRI 2.2.5, MRI 2.3.3, JRuby 9.1.6.0. It can be reproduced by:
```
$ cd activemodel
$ NO_FORK=1 bundle exec rake test
```
If we wrap original arguments in quotes, it will be considered as a one big single argument.
Later, [`rake/rake_test_loader.rb`](https://github.com/ruby/rake/blob/7863b97/lib/rake/rake_test_loader.rb#L15)
will iterate over ARGS and try to require that huge single "argument" (which is a list of multiple .rb files).
This leads to an exception:
```

Originally quotes were introduced in https://github.com/rails/rails/pull/19819 to fix MRI 2.2.2.
The fix solves issue on all affected platforms: MRI 2.2.5, MRI 2.3.3, JRuby 9.1.6.0.
Prior to this commit, `3.months - 3.months` would result in a duration
that has the "parts" of `[[:months, 3], [:months, -3]]`. This would mean
that it was subtly different than `2.months - 2.months`. When applied to
a time, the date might actually change if the resulting day doesn't
exist however many months in the future, even though in both cases we
just wanted to add `0`, which should always be an identity operation.
With this change, we now store the parts as a hash, so `3.months -
3.months` is simply stored as `{ months: 0 }`.
`depend_on` message format is `"No such file to load -- %s.rb"`.
But `require_dependency` message is missing `.rb` suffix.
```
% git grep -n 'No such file to load'
actionview/test/actionpack/abstract/helper_test.rb:112: assert_equal "No such file to load -- very_invalid_file_name.rb", e.message
activesupport/lib/active_support/dependencies.rb:245: def require_dependency(file_name, message = "No such file to load -- %s.rb")
activesupport/lib/active_support/dependencies.rb:333: def depend_on(file_name, message = "No such file to load -- %s.rb")
```
This fixes an error where the test runner would try and run
XMLMiniEngineTest like a normal test class, except it's abstract. Now,
to circumvent this, we don't include any of the actual tests in
XMLMiniEngineTest; they are wrapped in a module that is included in
subclass when they inherit from XMLMiniEngineTest. Pretty neat, huh?
Created a new module (a la Action Cable subscription adapter's test
suite) to be included in all sub class test to ensure compatability and
reduce duplicated code.
Will help get rid of errors like the following:
```
1) Error:
JDOMEngineTest#test_order=:
ArgumentError: wrong number of arguments (0 for 1)
/Users/jon/code/rails/rails/activesupport/lib/active_support/core_ext/module/attribute_accessors.rb:106:in `test_order='
```
The issue presented in #26246 showed a deeper underlying problem. When
we fell back to the exception handler for an exceptions cause, we were
calling that handler with the outer raised exception. This breaks the
calling code's expectations, especially if the exception has methods on
it behond those from `StandardError`.
AS::Testing::Isolation has two ways to isolate the process:
forking and subprocessing. The second way is used on JRuby and other
platforms that don't support forking.
The way how subprocessing works is that we prepare a command to run a
new process:
```
/opt/rubies/2.3.0/bin/ruby -I{skipped_load_path} test/initializable_test.rb '' -nInitializableTests::Basic#test_Initializer_provides_context's_class_name
```
As you see, there's unescaped quote at the end of the line.
It leads to:
```
sh: -c: line 0: unexpected EOF while looking for matching `''
sh: -c: line 1: syntax error: unexpected end of file
```
This fixes tests on MRI + NO_FORK variable and on JRuby 🎉
This reverts commit bad3a120f1690f393d8f6204b3ceee60f0ce707b, reversing
changes made to 2384317465ccb1dfca456a2b7798714b99f32711.
Reason: Adding a new option in the API for something that can be done
with a `#presence` check could do.
