Currently `ActiveSupport::Duration` implicitly converts to a seconds
value when used in a calculation except for the explicit examples of
addition and subtraction where the duration is the receiver, e.g:
>> 2 * 1.day
=> 172800
This results in lots of confusion especially when using durations
with dates because adding/subtracting a value from a date treats
integers as a day and not a second, e.g:
>> Date.today
=> Wed, 01 Mar 2017
>> Date.today + 2 * 1.day
=> Mon, 10 Apr 2490
To fix this we're implementing `coerce` so that we can provide a
deprecation warning with the intent of removing the implicit coercion
in Rails 5.2, e.g:
>> 2 * 1.day
DEPRECATION WARNING: Implicit coercion of ActiveSupport::Duration
to a Numeric is deprecated and will raise a TypeError in Rails 5.2.
=> 172800
In Rails 5.2 it will raise `TypeError`, e.g:
>> 2 * 1.day
TypeError: ActiveSupport::Duration can't be coerced into Integer
This is the same behavior as with other types in Ruby, e.g:
>> 2 * "foo"
TypeError: String can't be coerced into Integer
>> "foo" * 2
=> "foofoo"
As part of this deprecation add `*` and `/` methods to `AS::Duration`
so that calculations that keep the duration as the receiver work
correctly whether the final receiver is a `Date` or `Time`, e.g:
>> Date.today
=> Wed, 01 Mar 2017
>> Date.today + 1.day * 2
=> Fri, 03 Mar 2017
Fixes#27457.
ActionMailer::Base#instrument_name and
ActionController::Base#instrument_name will be frequently called once
caching is enabled. So it's better to freeze them instead of create new
string on every call.
Also, the instrument name in #instrument_fragment_cache will usually
be "write_fragment.action_controller" or
"read_fragment.action_controller". So freezing them might also gain some
performance improvement. We have done something like this in other places:
https://github.com/rails/rails/blob/master/actionview/lib/action_view/template.rb#L348
The raw_source method is documented as returning the exact value that
was used to create the body; mutating it breaks that contract.
Additionally, if the value used to create the body is blank, raw_source
returns a frozen string which causes the interceptor to raise an error.
If we create nested (namespaced) rails engine such like bukkits-admin,
`bin/rails g scaffold User name:string age:integer`
will create
`bukkits-admin/app/controllers/bukkits/users_controller.rb`
but it should create
`bukkits-admin/app/controllers/bukkits/admin/users_controller.rb`.
In #6643, we changed `namespaced_path` as root path
because we supposed application_controller is always in root
but nested rails engine's application_controller will not.
All indentation was normalized by rubocop auto-correct at 80e66cc4d9.
But comments was still kept absolute position. This commit aligns
comments with method definitions for consistency.
Usually users extends tests classes doing something like:
ActionView::TestCase.include MyCustomTestHelpers
This is bad because it will load the ActionView::TestCase right aways
and this will load ActionController::Base making its on_load hooks to
execute early than it should.
One way to fix this is using the on_load hooks of the components like:
ActiveSupport.on_load(:action_view) do
ActionView::TestCase.include MyCustomTestHelpers
end
The problem with this approach is that the test extension will be only
load when ActionView::Base is loaded and this may happen too late in the
test.
To fix this we are adding hooks to people extend the test classes that
will be loaded exactly when the test classes are needed.
