[ci skip] Declare `product` as `_product partial`

Show an error message if bundler 1.10.x is not installed when reporting bugs

Remove `config.assets.version` from Configuring Rails Application Guide

modify console of app method in that can use the path helpers

Add the bug report templates to the Travis CI build

Remove warning for setting eager_load

The bug report templates are now executed from the `ci/travis.rb` when
`GEM` contains `guides`.

I started by creating a `test` task in `guides/Rakefile` to handle this,
but since inline `gemfile` must not be executed with `bundle exec`, that
rake task would not be consistent with others. So I went back by
executing them directly from `Build`.

Use inline Gemfile dependency when reporting gem bugs

[ci skip] Fix `thoughtbot` capitalization

The company name is spelled `thoughtbot` per
https://github.com/thoughtbot/presskit/blob/master/README.md#name

AppTemplate::Application.new does not run load hooks.

To load this configuration we need to use create which will 
run load hooks to load this configuration.

[ci skip] Use inline Gemfile dependency when reporting bugs

Require active_support/duration.

ActiveSupport::TimeWithZone references `ActiveSupport::Duration` but
does not require it, which can result in a `LoadError` when required
directly without requiring a component less granular like
`active_support/time`, where the autoload for `ActiveSupport::Duration`
is set up.

Removed duplicate test cases for template execution

Apply Active Record suppression to all saves

It was not being applied to creates and updates attempted through the
non-bang save methods. This means that, for example, creation of
records for singular associations through the `create_*` methods was
not appropriately ignored in .suppress blocks.

With Bundler `1.10.3`, it is possible to list the gems inline without the
need to create a `Gemfile` if none is found in the current directory.

Also add a CHANGELOG entry for #18587

[ci skip]

Allow configuration of ActionMailer queue name

The `GetIp` class doesn't need to keep a reference to the middleware, so
there is no reason to pass the middleware instance to the `GetIp` class

[ci skip] fix the `collection.clear` guide

Improve the guide about `has_many` `collection.clear` to indicate
the behavior for each dependent strategy according to
`collection.delete_all`.

Based on #17179, I changed the `collection.delete` docs to also
clarify the default strategy for each `hm` and `hm:t` associations.

Fixes #20170.

This reverts commit a9d58c77, reversing
changes made to 041c2c87.

Reason: The old behavior is how it was working in previous version of
Rails since 4.0.x so it is not safe to backport to a stable branch.

Use block variable instead of global

```ruby
require 'benchmark/ips'

Benchmark.ips do |x|
  x.report("$&") {
    "foo".sub(/f/) { $&.upcase }
  }
  x.report("block var") {
    "foo".sub(/f/) {|match| match.upcase }
  }
end

```

```
Calculating -------------------------------------
                  $&    48.658k i/100ms
           block var    49.666k i/100ms
-------------------------------------------------
                  $&    873.156k (± 9.3%) i/s -      4.331M
           block var    969.744k (± 9.2%) i/s -      4.818M
```

It's faster, and gets rid of a few "magic" global variables
