Since Rails 4.0, we add an ORDER BY in the `first` method to ensure consistent results among different database engines. But for singular associations this behavior is not needed since we will have one record to return. As this ORDER BY option can lead some performance issues we are removing it for singular associations accessors. Fixes #12623.

This fixes a bug where `select(:id)` combined with `joins()` raised: ``` ActiveRecord::StatementInvalid: SQLite3::SQLException: ambiguous column name: id: SELECT id, authors.author_address_id FROM "posts" INNER JOIN "authors" ON "authors"."id" = "posts"."author_id" ORDER BY posts.id LIMIT 3 ``` The `select_values` are still String and Symbols because other parts (mainly calculations.rb) rely on that fact. /cc @tenderlove

Before this patch find_in_batches raises this error only on second iteration. So you will know about the problem only when you get the batch size threshold.

With the introduction of `#second` method and friends, we added an offsets hash which replaced the @first variable, so removing it from the reset method to avoid creating an unused variable now. Introduced in bc625080.

This variable is internal and should not be exposed to end users

This commit bring the famous ordinal Array instance methods defined in ActiveSupport into ActiveRecord as fully-fledged finders. These finders ensure a default ascending order of the table's primary key, and utilize the OFFSET SQL verb to locate the user's desired record. If an offset is defined in the query, calling #second adds to the offset to get the actual desired record. Fixes #13743.

This fixes a regression (#13744) that was caused by 67d8bb96. In 67d8bb96, we introduced lazy rollback for records, such that the record's internal states and attributes are not restored immediately after a transaction rollback, but deferred until they are first accessed. This optimization is only performed when the model does not have any transactional callbacks (e.g. `after_commit` and `after_create`). Unfortunately, the models used to test the affected codepaths all comes with some sort of transactional callbacks. Therefore this codepath remains largely untested until now and as a result there are a few issues in the implementation that remains hidden until now. First, the `sync_with_transaction_state` (or more accurately, `update_attributes_from_transaction_state`) would perform the synchronization prematurely before a transaction is finalized (i.e. comitted or rolled back). As a result, when the actuall rollback happens, the record will incorrectly assumes that its internal states match the transaction state, and neglect to perform the restore. Second, `update_attributes_from_transaction_state` calls `committed!` in some cases. This in turns checks for the `destroyed?` state which also requires synchronization with the transaction stae, which causes an infnite recurrsion. This fix works by deferring the synchronization until the transaction has been finalized (addressing the first point), and also unrolled the `committed!` and `rolledback!` logic in-place (addressing the second point). It should be noted that the primary purpose of the `committed!` and `rolledback!` methods are to trigger the relevant transactional callbacks. Since this code path is only entered when there are no transactional callbacks on the model, this shouldn't be necessary. By unrolling the method calls, the intention here (to restore the states when necessary) becomes more clear.

The `subclass_from_attrs` method is called even if the column specified by the `inheritance_column` setting doesn't exist. This prevents setting associations via the attributes hash if the association name clashes with the value of the setting, typically `:type`. This worked previously in Rails 3.2.

Closes #13650, #13672 This is an alternate implementation to solve #13650. Currently form fields contain the enum value (eg. "1"). This breaks because the setter `enum=` expects the label (eg. "active"). ActiveRecord::Enum allows you to use labels in your application but store numbers. We should make sure that all parts after AR are dealing with labels and not the underlying mapping to a number. This patch defines `_before_type_cast` on every enum column to return the label. This method is later used to fetch the value to display in form fields. I deliberately copied the implementation of the enum getter instead of delegating to it. This allows you to overwrite the getter and for example return a `Value Object` but have it still work for form fields.

Currently Active Record can be configured via the environment variable `DATABASE_URL` or by manually injecting a hash of values which is what Rails does, reading in `database.yml` and setting Active Record appropriately. Active Record expects to be able to use `DATABASE_URL` without the use of Rails, and we cannot rip out this functionality without deprecating. This presents a problem though when both config is set, and a `DATABASE_URL` is present. Currently the `DATABASE_URL` should "win" and none of the values in `database.yml` are used. This is somewhat unexpected to me if I were to set values such as `pool` in the `production:` group of `database.yml` they are ignored. There are many ways that active record initiates a connection today: - Stand Alone (without rails) - `rake db:<tasks>` - ActiveRecord.establish_connection - With Rails - `rake db:<tasks>` - `rails <server> | <console>` - `rails dbconsole` We should make all of these behave exactly the same way. The best way to do this is to put all of this logic in one place so it is guaranteed to be used. Here is my prosed matrix of how this behavior should work: ``` No database.yml No DATABASE_URL => Error ``` ``` database.yml present No DATABASE_URL => Use database.yml configuration ``` ``` No database.yml DATABASE_URL present => use DATABASE_URL configuration ``` ``` database.yml present DATABASE_URL present => Merged into `url` sub key. If both specify `url` sub key, the `database.yml` `url` sub key "wins". If other paramaters `adapter` or `database` are specified in YAML, they are discarded as the `url` sub key "wins". ``` ### Implementation Current implementation uses `ActiveRecord::Base.configurations` to resolve and merge all connection information before returning. This is achieved through a utility class: `ActiveRecord::ConnectionHandling::MergeAndResolveDefaultUrlConfig`. To understand the exact behavior of this class, it is best to review the behavior in activerecord/test/cases/connection_adapters/connection_handler_test.rb though it should match the above proposal.

- Earlier, change_table was creating database-agnostic object. - After this change, it will create correct object based on current database adapter. - This will ensure that create_table and change_table will get same objects. - This makes update_table_definition method public and nodoc. - Fixes #13577 and #13503
