patricksrobertson/bigserial_id_not_identifying_pk"

In #10410 it was noted that you can no longer create PK's with the
type of bigserial in PostgreSQL in 4.0.0.rc1. This is mostly
because the newer adapter is checking for column type with the
id column instead of just letting it pass through like it did
before.
Side effects:
You may just create a PK column of a type that you really don't
want to be your PK. As far as I can tell this was allowed in 3.2.X
and perhaps an exception should be raised if you try and do
something extremely dumb.

counter cache
At present, calling destroy multiple times on the same record results
in the belongs_to counter cache being decremented multiple times. With
this change the record is checked for whether it is already destroyed
prior to decrementing the counter cache.

fixes #10419
Following code should raise IrreversibleMigration. But the code was
failing since options is an array and not a hash.
def change
change_table :users do |t|
t.remove_index [:name, :email]
end
end
Fix was to check if the options is a Hash before operating on it.

assignment
For one-to-one nested associations, if you build the new (in-memory)
child object yourself before assignment, then the NestedAttributes
module will not overwrite it, e.g.:
class Member < ActiveRecord::Base
has_one :avatar
accepts_nested_attributes_for :avatar
def avatar
super || build_avatar(width: 200)
end
end
member = Member.new
member.avatar_attributes = {icon: 'sad'}
member.avatar.width # => 200

autosave_association issue that occurs when table has unique index (resubmission)

fixes bug introduced by #3329
These are the conditions necessary to reproduce the bug:
- For an association, autosave => true.
- An association record is being destroyed
- A new association record is being created.
- There is a unique index one of the association's fields.
- The record being created has the same value as the record being
destroyed on the indexed field.
Before, the deletion of records was postponed until after all
insertions/saves. Therefore the new record with the identical value in
the indexed field caused a non-unique value error to be thrown at the database
level.
With this fix, the deletions happen first, before the insertions/saves.
Therefore the record with the duplicate value is gone from the database
before the new record is created, thereby avoiding the non-uniuqe value
error.

test_mysql_integer_not_null_defaults in test/cases/defaults_test.rb was
failing. This test relies on the connection being in strict mode. By
default a new connection is not in strict mode, but Active Record
automatically places it in strict mode.
ActiveSchemaTest overwrites the connection's #execute method in order to
prevent SQL statements from actually being executed. One of the
operations which is performed in ActiveSchema test is a #recreate_database.
Since 2088bf27981137a2c6c8b2f718f33b417b4045af, recreate_database on
mysql or mysql2 will trigger a reconnect.
Due to the implementation of the hacking of #execute in
ActiveSchemaTest, this reconnect would take place, but the connection
would *not* be placed in strict mode because #execute had been
overridden to prevent SQL queries hitting the database.
Therefore, after ActiveSchemaTest, the connection would no longer be in
strict mode, causing test_mysql_integer_not_null_defaults to fail.
I don't think that the way that ActiveSchemaTest is implemented is
particularly nice or clean, but I have taken steps to make its hacks
more isolated - it now create a separate connection object which is
thrown away after the test, and the hacks are applied on the singleton
class of this object.

Handle aliased attributes in AR::Relation

When using symbol keys, ActiveRecord will now translate aliased attribute names to the actual column name used in the database:
With the model
class Topic
alias_attribute :heading, :title
end
The call
Topic.where(heading: 'The First Topic')
should yield the same result as
Topic.where(title: 'The First Topic')
This also applies to ActiveRecord::Relation::Calculations calls such as `Model.sum(:aliased)` and `Model.pluck(:aliased)`.
This will not work with SQL fragment strings like `Model.sum('DISTINCT aliased')`.

activerecord/lib/active_record/associations.rb states:
# [association=(associate)]
# Assigns the associate object, extracts the primary key, sets it as the foreign key,
# and saves the associate object.
Since commit 42dd5d9f2976677a4bf22347f2dde1a8135dfbb4 to fix #7191, this
is no longer the case if the associate has changed, but is the same
object. For example:
# Pirate has_one :ship
pirate = Pirate.create!(catchphrase: "A Pirate")
ship = pirate.build_ship(name: 'old name')
ship.save!
ship.name = 'new name'
pirate.ship = ship
That last line should trigger a save. Although we are not changing the
association, the associate (ship) has changed.
