* Apply record state based on parent transaction stateeileencodes2017-07-011-0/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's say you have a nested transaction and both records are saved. Before the outer transaction closes, a rollback is performed. Previously the record in the outer transaction would get marked as not persisted but the inner transaction would get persisted. ```ruby Post.transaction do post_one.save # will get rolled back Post.transaction(requires_new: true) do post_two.save # incorrectly remains marked as persisted end raise ActiveRecord::Rollback end ``` To fix this the PR changes transaction handling to have the child transaction ask the parent how the records should be marked. When there are child transactions, it will always be a SavpointTransaction because the stack isn't empty. From there we pass the parent_transaction to the child SavepointTransaction where we add the children to the parent so the parent can mark the inner transaction as rolledback and thus mark the record as not persisted. `update_attributes_from_transaction_state` uses the `completed?` check to correctly mark all the transactions as rolledback and the inner record as not persisted. ```ruby Post.transaction do post_one.save # will get rolled back Post.transaction(requires_new: true) do post_two.save # with new behavior, correctly marked as not persisted on rollback end raise ActiveRecord::Rollback end ``` Fixes #29320
* Deprecate and replace `set_state` methodeileencodes2017-07-011-0/+38
| | | | | | | | | | | | | `set_state` was directly setting the transaction state instance variable. It's better to set the state via specific methods (`rollback!` and `commit!` respectively. While undocumented and untested, it's possible someone is using `set_state` in their app or gem so I've added a deprecation notice to it. No where in the app do we use `nullify!` but I wanted to keep existing behavior while replacing the method with a better pattern.

* | | | | Deprecate delegating to `arel` in `Relation`Ryuta Kamizono2017-06-291-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Active Record doesn't rely delegating to `arel` in the internal since 425f2ca. The delegation is a lower priority than delegating to `klass`, so it is pretty unclear which method is delegated to `arel`. For example, `bind_values` method was removed at b06f64c (a series of changes https://github.com/rails/rails/compare/79f71d3...b06f64c). But a relation still could respond to the method because `arel` also have the same named method (#28976). Removing the delegation will achieve predictable behavior.

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.
