rexml is only used in the xml_mini backend and it should be the users
choice if they want to use that feature or not. If they do we will warn
them that installing rexml is needed like we do with all backends.
Let's bump Zeitwerk in preparation for Rails 6.1.
With Zeitwerk 2.3, applications can enable reloading and eager loading
at the same time. As of this writing, Rails does not implement that
logic, but if we do we know the dependency is in place to support it.
Zeitwerk minor releases are backwards compatible, should be a seamlessly
upgrade.
Fix: https://github.com/rails/rails/issues/37650
The classic autoloader used to totally unregister any constant that
failed midway. Which mean `"SomeConst".constantize` was idempotent.
However Zeitwerk rely on normal `Kernel#require` behavior, which mean
that if an exception is raised during a class/module definition,
it will be left incompletely defined. For instance:
```ruby
class FooController
::DoesNotExist
def index
end
end
```
Will leave `FooController` defined, but without its `index` method.
Because of this, when silencing a NameError, it's important
to make sure the missing constant is really the one we were trying
to load.
This commit more or less undoes 9b5401f, restores autoloaded? not to
touch the descendants tracker, and autoloaded_constants because it is
documented in the guide.
The original message from Zeitwerk is "can't reload, please call
loader.enable_reloading before setup (Zeitwerk::Error)", which is not
very informative for Rails programmers.
Rails should err with a message worded in terms of its interface.
Rails.autoloader and Rails.once_autoloader was just tentative API good
enough for a first patch. Rails.autoloader is singular and does not
convey in its name that there is another autoloader. That might be
confusing, for example if you set a logger and miss traces. On the other
hand, the name `once_autoloader` is very close to being horrible.
Rails.autoloaders.main and Rails.autoloaders.once read better for my
taste, and have a nice symmetry. Also, both "main" and "once" are four
letters long, short and same length.
They are tagged as "rails.main" and "rails.once", respectively.

We had a discussion on the Core team and we don't want to expose this information
as a JSON endpoint and not by default.
It doesn't make sense to expose this JSON locally and this controller is only
accessible in dev, so the proposed access from a production app seems off.
This reverts commit 8eaffe7e89, reversing
changes made to b6e4305c3b.
Generally followed the pattern for https://github.com/rails/rails/pull/32034
* Removes needless CI configs for 2.4
* Targets 2.5 in rubocop
* Updates existing CHANGELOG entries for fewer merge conflicts
* Removes Hash#slice extension as that's inlined on Ruby 2.5.
* Removes the need for send on define_method in MethodCallAssertions.
