This slightly change the code in the Arel to allow +/-INFINITY as open
ended since the Active Record expects that behavior. See 5ecbeda0.

Allow space for mysql enum and set keyword.

Preserve key order of #fetch_multi

Respect Rails.env when running `rails yarn:install`

Add Action Text to guides [ci skip]

Add `--skip-action-text` option to `rails new`

Add `action_text_content` hook to the guide [ci skip]

Test actiontext on Rails 6.0

Remove comment from `actiontext/actiontext.gemspec`

Fix API docs of `ActionText::RichText` [ci skip]

Use ES6 and Webpacker in ActionCable guide.

- config.load_defaults 6.0 in the dummy app and
  fix the test since by default rails 6.0 configured
  does not generate "utf8" hidden input, see #32125
- Use `ActiveRecord::Migration[6.0]` in the dummy app
  since actiontext will be since Rails 6.0
- Fix `CreateActiveStorageTables` migration in the dummy app.
  Add `t.foreign_key :active_storage_blobs, column: :blob_id`
  It was added in 2ae3a295.
- `rails/actiontext$ yarn install`

Since PR#34816 was merged in c6ef670a,
we should add this option for flexibility, and consistency.

- Move some actiontext/README.md content to Action Text Overview guide
- I added WIP label to that guide since we definitely want to complement it.
- Add Action Text to Major Features of Rails 6.0

Similar approach was used in #34812

See actiontext/lib/action_text/content.rb:132

This comment was autogenerated, see
`railties/lib/rails/generators/rails/plugin/templates/%name%.gemspec.tt`
Since actiontext is well described in this file, I think we shouldn't
keep this comment. Note that this commit is more like cosmetic change,
so it is OK if we don't merge this.

This text should appear on the page
https://api.rubyonrails.org/v6.0/classes/ActionText/RichText.html

Import Action Text

Also, make tests and examples for individual execution counters
clearer, as it wasn't entierly clear what would happen in this case:

```
retry_on CustomException, OtherException, attempts: 3
```

The job would be retried at most 3 times in total, for both
CustomException and OtherException. To have the job retry 3 times at
most for each exception individually, the following retry_on
declarations are necessary:

```
retry_on CustomException, attempts: 3
retry_on OtherException, attempts: 3
```

[ci skip]

When using the `rich_text_area_tag` form helper from within a Rails
engine, the direct_upload_url and blob_url_template options would
default to non-existent routes.

By prefixing these routes with `main_app` we ensure the application
root is used rather than the engine.

Test Action Mailbox configurations

Fix `new_framework_defaults_6_0.rb` file

Add `ActiveModel::Errors#of_kind?`

Clarify `delegate_missing_to` [ci skip]

Since #34864 removed explicit receiver to clarify the
purpose of `delegate_missing_to`, I think it will be
better to do the same a few lines above to easier figure
out that `delegate_missing_to` defines `method_missing`,
`respond_to_missing?` when comparing these examples.

`Rails.application.config.active_job.return_false_on_aborted_enqueue`
should be commented as well.

When no environment variables are set the expectation is that we are in
development.
