locking is enabled
This issue is caused by `@_trigger_update_callback` won't be updated due
to `_update_record` in `Locking::Optimistic` doesn't call `super` when
optimistic locking is enabled.
Now optimistic locking concern when updating is supported by
`_update_row` low level API, therefore overriding `_update_record` is no
longer necessary.
Removing the method just fix the issue.
Closes #29096.
Closes #29321.
Closes #30823.

Currently primary key value can not be updated if a record has a locking
column because of `_update_record` in `Locking::Optimistic` doesn't
respect `id_in_database` as primary key value unlike in `Persistence`.
And also, if a record has dirty primary key value, it may destroy any
other record by the lock version of dirty record itself.
When updating/destroying persisted records, it should identify
themselves by `id_in_database`, not by dirty primary key value.

Fix destroying existing object does not work well when optimistic
locking enabled and `locking column` is null in the database.

Currently, loading the schema (schema_load)
accesses the locking column (locking_column)
which defaults the value (reset_locking_column)
which invalidates the schema (reload_schema_from_cache)
which forces another schema load.
Good news:
The second schema_load does accesses locking_column,
but locking_column is set, so it does not reset_locking_column
and it does not trigger an infinite loop.
The solution is not invalidate the cache while default locking_column

Make sure we handle explicitly passed nil's to lock_version as well.
An explicitly passed nil value is now converted to 0 on LockingType,
so that we don't end up with ActiveRecord::StaleObjectError in update record
optimistic locking

It's finally finished!!!!!!! The reason the Attributes API was kept
private in 4.2 was due to some publicly visible implementation details.
It was previously implemented by overloading `columns` and
`columns_hash`, to make them return column objects which were modified
with the attribute information.
This meant that those methods LIED! We didn't change the database
schema. We changed the attribute information on the class. That is
wrong! It should be the other way around, where schema loading just
calls the attributes API for you. And now it does!
Yes, this means that there is nothing that happens in automatic schema
loading that you couldn't manually do yourself. (There's still some
funky cases where we hit the connection adapter that I need to handle,
before we can turn off automatic schema detection entirely.)
There were a few weird test failures caused by this that had to be
fixed. The main source came from the fact that the attribute methods are
now defined in terms of `attribute_names`, which has a clause like
`return [] unless table_exists?`. I don't *think* this is an issue,
since the only place this caused failures were in a fake adapter which
didn't override `table_exists?`.
Additionally, there were a few cases where tests were failing because a
migration was run, but the model was not reloaded. I'm not sure why
these started failing from this change, I might need to clear an
additional cache in `reload_schema_from_cache`. Again, since this is not
normal usage, and it's expected that `reset_column_information` will be
called after the table is modified, I don't think it's a problem.
Still, test failures that were unrelated to the change are worrying, and
I need to dig into them further.
Finally, I spent a lot of time debugging issues with the mutex used in
`define_attribute_methods`. I think we can just remove that method
entirely, and define the attribute methods *manually* in the call to
`define_attribute`, which would simplify the code *tremendously*.
Ok. now to make this damn thing public, and work on moving it up to
Active Model.

Building the Arel AST, and manipulating the relation manually like this
is prone to errors and breakage as implementation details change from
underneath it.

The reason this bug occured is that we never actually check to see if
this column has changed from it's default, since it was never assigned
and is not mutable.
It appears I was wrong in b301c40224c6d15b539dbcc7485adb44d810f88c, with
my statement of "there is no longer a case where a given value would
differ from the default, but would not already be marked as changed."
However, I chose not to revert the deletion of
`initialize_internals_callback` from that commit, as I think a solution
closer to where the problem lies is less likely to get erroneously
removed. I'm not super happy with this solution, but it mirrors what is
being done in `_update_record`, and a fix for one should work for the
other.
I toyed with the idea of changing the definition of `changed?` on the
type to `changed_in_place?`. If we type cast the raw value, it'll break
a test about updating not modifying the lock column if nothing else was
changed. We could have the definition check if `raw_old_value` is `nil`,
but this feels fragile and less intention revealing. It would, however,
have the benefit of cleaning up old data that incorrectly persisted as
`nil`.

Part of the larger refactoring to remove type casting from Arel. We can
inform it that we already have the right type by wrapping the value in
an `Arel::Nodes::Quoted`. This commit can be reverted when we have
removed type casting from Arel in Rail 5.1

Oh hey, we got to remove some code because of that!

We are moving this behavior out to an object that we would like to keep
separated from `ActiveRecord::Base`, which means not passing the class
object to it. As such, we need to stop using `instance_exec`, and
instead close over the subclass on global type decorators that are
applied in `Base`.

Adding `# :nodoc:` to the parent `class` / `module` is not going
to ignore nested classes or modules.
There is a modifier `# :nodoc: all` but sadly the containing class
or module will continue to be in the docs.
