This fixes a regression (#13744) that was caused by 67d8bb9.
In 67d8bb9, 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.

Just create a local variable whenever we need the record, rather than
doing an extra find for every test on the setup method.

Ensure the child can actually be touched. The `Bulb` model has no
timestamp column, thus trying to touch it would return `nil`.

This makes the tests inside `migration_test.rb` order independent.
The assignments to `Reminder.table_name_prefix` and `Reminder.table_name_suffix`
previously leaked and had impact on following test cases.
This patch isolates the assignments on a throw-away subclass.

This solves order dependent issues where the last test
leaked the query cache state. This resulted in the following error:

This fixes broken `rake test_sqlite3_mem` suite for Active Record.
The problem is that that the old database with the schema is lost
when establishing a new connection. Upon reconnting we are left
with a blank database and tests down the line start failing.

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.

- 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

Previously, this would give an `ArgumentError`:
class Issue < ActiveRecord::Base
enum :status, [:open, :finished]
end
Issue.open.build # => ArgumentError: '0' is not a valid status
Issue.open.create # => ArgumentError: '0' is not a valid status
PR #13542 muted the error, but the issue remains. This commit fixes
the issue by allowing the enum value to be written directly via the
setter:
Issue.new.status = 0 # This now sets status to :open
Assigning a value directly via the setter like this is not part of the
documented public API, so users should not rely on this behavior.
Closes #13530.

Previously, the writer methods would simply check whether the passed
argument was the symbol representing the integer value of an enum field.
Therefore, it was not possible to specify the numeric value itself but
the dynamically defined scopes generate where clauses relying on this
kind of values so a chained call to a method like `find_or_initialize_by`
would trigger an `ArgumentError`.
