Fix typo for touch later test description. laster -> later 

- It will return false in Rails 6.1 not 6.0. Also fixed the default
  value which is true for new applications.

Add missing `touch_all` delegation to relation

Follow up of #31513.

[ci skip] Mark ActiveRecord::TouchLater as private doc

Do not exclude paths in the global level of Code Climate

We use only RuboCop in Code Climate and exclude paths are specified in
RuboCop's setting.

The global level excludes paths should not be specified to match the
behavior of local and CodeClimate.

This is completely same with `test_last`.

Stash `left_joins` into `joins` to deduplicate redundant LEFT JOIN

fix typo in the guides (use Rails instead of rails) [ci skip]

Originally the `JoinDependency` has the deduplication for eager loading
(LEFT JOIN). This re-uses that deduplication for `left_joins`.

And also, This makes left join order into part of joins, i.e.:

Before:

```
association joins -> stash joins (eager loading, etc) -> string joins -> left joins
```

After:

```
association joins -> stash joins (eager loading, left joins, etc) -> string joins
```

Now string joins are able to refer left joins.

Fixes #34325.
Fixes #34332.
Fixes #34536.

Add documentation for 'after_save_commit' [ci skip]

Adds 'detach_from' to 'ActiveSupport::Subscriber' to detach a subscriber from a namespace.

Fix arity warning for template handlers

Mainly to help with knowning which template is reponsible for the
warning.

handler.class # => Class

handler.to_s # => Coffee::Rails::TemplateHandler

Before:

Change:
  >> Class#call(template)
To:
  >> Class#call(template, source)

After:

Change:
  >> Coffee::Rails::TemplateHandler.call(template)
To:
  >> Coffee::Rails::TemplateHandler.call(template, source)

Follow up of #26764 and #35700.

And add test case for #35700.

Fix deprecation warning about variants and formats

  https://github.com/rails/rails/pull/35406, the `formats` and
  `variants` methods are deprecated in favor of `format` and `variant`.

Fix `count(:all)` with eager loading and explicit select and order

This follows up ebc09ed9.

We've still experienced a regression for `size` (`count(:all)`) with
eager loading and explicit select and order when upgrading Rails to 5.1.

In that case, the eager loading enforces `distinct` to subselect but
still keep the custom select, it would cause the ORDER BY with DISTINCT
issue.

```
% ARCONN=postgresql bundle exec ruby -w -Itest test/cases/relations_test.rb -n test_size_with_eager_loading_and_custom_select_and_order
Using postgresql
Run options: -n test_size_with_eager_loading_and_custom_select_and_order --seed 8356

# Running:

E

Error:
RelationTest#test_size_with_eager_loading_and_custom_select_and_order:
ActiveRecord::StatementInvalid: PG::InvalidColumnReference: ERROR:  for SELECT DISTINCT, ORDER BY expressions must appear in select list
LINE 1: ..." ON "comments"."post_id" = "posts"."id" ORDER BY comments.i...
                                                             ^
```

As another problem on `distinct` is enforced, the result of `count`
becomes fewer than expected if `select` is given explicitly.

e.g.

```ruby
Post.select(:type).count
# => 11

Post.select(:type).distinct.count
# => 3
```

As long as `distinct` is enforced, we need to care to keep the result of
`count`.

This fixes both the `count` with eager loading problems.

Refactor `Relation#cache_key` is moved from `CollectionCacheKey#collection_cache_key`

The implementation of `Relation#cache_key` depends on some internal
relation methods (e.g. `apply_join_dependency`, `build_subquery`), but
somehow that implementation exists on the model class
(`collection_cache_key`), it sometimes bothers to me.

This refactors that implementation moves to `Relation#cache_key`, then
we can avoid `send` to call internal methods.

Optimizer hints should be applied on Top level query as much as possible

Fix partial caching ignore repeated items issue

I've experienced this issue in our app, some hints only works on Top
level query (e.g. `MAX_EXECUTION_TIME`).

This is because we only use hash to maintain the result. So when the key
are the same, the result would be skipped. The solution is to maintain
an array for tracking every item's position to restructure the result.
