| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The delegation was needed since passing `relation` with `relation.bound_attributes`. It should use `relation.arel` in that case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Passing `klass.connection` is redundant because `AssociationScope` is passed an association itself and an association has `klass`.

Therefore, query cache is unavailable when entering the ActiveRecord::Base.cache block without being connected. ```ruby ActiveRecord::Base.cache do Task.find(1) # access to database. Task.find(1) # access to database. unavailable query cache end ``` If we use query cache with batch script etc, we need to connect before that. ```ruby Task.connection ActiveRecord::Base.cache do Task.find(1) # access to database. Task.find(1) # available query cache end ``` Before version 3.1, query cache had been enabled if a configuration was set up. In order to solve the `DATABASE_URL` issue(#8074), ActiveRecord has checked whether a connection is connected or not. Today, ActiveRecord.configurations respect `DATABASE_URL`. https://github.com/rails/rails/blob/master/activerecord/lib/active_record/core.rb#L46

This cache is cleared in AR::Relation#reset, but not in CollectionProxy#reset or CollectionProxy#reload. Because of this, since #29098, calling #first/#find_nth/etc after calling #reload or #reset on an association could return a stale record. This is an issue both when the full association target is loaded and when the item is loaded in #find_nth. This commit solves the problem by clearing the `@offsets` cache in CollectionProxy#reset and CollectionProxy#reload.

Previously, the way to determine if the value is scalar was to try quoting it. If `quote` raised with an error than the value has to be converted to YAML. This flow is not very obvious. Ideally we could have a `quotable?` method in the connection, but I think that we can avoid begin/rescue block by simply checking if the value is Array or Hash. https://github.com/rails/rails/commit/aa31d21f5f4fc4d679e74a60f9df9706da7de373

INNER JOIN posts ON... LEFT OUTER JOIN comments ON...` instead of doing `SELECT ... INNER JOIN posts ON... INNER JOIN comments ON...`. This behavior is unexpected and makes little sense as, basically, doing `Post.joins(:comments)` means I want posts that have comments. Turning it to a LEFT JOIN means I want posts and join the comments data, if any. We can see this problem directly in the existing tests. The test_relation_merging_with_merged_joins_as_symbols only does joins from posts to comments to ratings while the ratings fixture isn't loaded, but the count is non-zero.
