`User.where(id: [[1,2],3])` was equal to `User.where(id:[1, 2, 3])`
in Rails 4.1.x but because of some refactoring in Arel this stopped
working in 4.2.0. This fixes it in Rails.

The name of the foreign key is not relevant from a users perspective.
Using random names resolves the urge to rename the foreign key when the
respective table or column is renamed.

Reliant on https://github.com/rails/rails/pull/15747 but pulled to a
separate PR to reduce noise. `has_many :through` associations have the
undocumented behavior of automatically detecting counter caches.
However, the way in which it does so is inconsistent with counter caches
everywhere else, and doesn't actually work consistently.
As with normal `has_many` associations, the user should specify the
counter cache on the `belongs_to`, if they'd like it updated.

Topics call `serialize :content`, which means that the values in the
database should be YAML encoded, and we would only expect to receive
YAML strings to `update_column` and `update_columns`.

This bug can be triggered when serializing record R (the instance) of type C
(the class), provided that the following conditions are met:
1. The name of one or more columns/attributes on C/R matches an existing private
method on C (e.g. those defined by `Kernel`, such as `format`).
2. The attribute methods have not yet been generated on C.
In this case, the matching private methods will be called by the serialization
code (with no arguments) and their return values will be serialized instead. If
the method requires one or more arguments, it will result in an `ArgumentError`.
This regression is introduced in d1316bb.
* * *
Attribute methods (e.g. `#name` and `#format`, assuming the class has columns
named `name` and `format` in its database table) are lazily defined. Instead of
defining them when a the class is defined (e.g. in the `inherited` hook on
`ActiveRecord::Base`), this operation is deferred until they are first accessed.
The reason behind this is that is defining those methods requires knowing what
columns are defined on the database table, which usually requires a round-trip
to the database. Deferring their definition until the last-possible moment helps
reducing unnessary work, especially in development mode where classes are
redefined and throw away between requests.
Typically, when an attribute is first accessed (e.g. `a_book.format`), it will
fire the `method_missing` hook on the class, which triggers the definition of
the attribute methods. This even works for methods like `format`, because
calling a private method with an explicit receiver will also trigger that hook.
Unfortunately, `read_attribute_for_serialization` is simply an alias to `send`,
which does not respect method visibility. As a result, when serializing a record
with those conflicting attributes, the `method_missing` is not fired, and as a
result the attribute methods are not defined one would expected.
Before d1316bb, this is negated by the fact that calling the `run_callbacks`
method will also trigger a call to `respond_to?`, which is another trigger point
for the class to define its attribute methods. Therefore, when Active Record
tries to run the `after_find` callbacks, it will also define all the attribute
methods thus masking the problem.
* * *
The proper fix for this problem is probably to restrict `read_attribute_for_serialization`
to call public methods only (i.e. alias `read_attribute_for_serialization` to
`public_send` instead of `send`). This however would be quite risky to change
in a patch release and would probably require a full deprecation cycle.
Another approach would be to override `read_attribute_for_serialization` inside
Active Record to force the definition of attribute methods:
def read_attribute_for_serialization(attribute)
self.class.define_attribute_methods
send(attribute)
end
Unfortunately, this is quite likely going to cause a performance degradation.
This patch therefore restores the behaviour from the 4-0-stable branch by
explicitly forcing the class to define its attribute methods in a similar spot
(when records are initialized). This should not cause any extra roundtrips to
the database because the `@columns` should already be cached on the class.
Fixes #15188.

Changed the call to a scope block to be evaluated with instance_eval.
The result is that ScopeRegistry can use the actual class instead of base_class when
caching scopes so queries made by classes with a common ancestor won't leak scopes.

conflicting private method defined on its ancestors.
The problem is that `method_defined_within?(name, klass, superklass)`
only works correclty when `klass` and `superklass` are both `Class`es.
If both `klass` and `superklass` are both `Class`es, they share the
same inheritance chain, so if a method is defined on `klass` but not
`superklass`, this method must be introduced at some point between
`klass` and `superklass`.
This does not work when `superklass` is a `Module`. A `Module`'s
inheritance chain contains just itself. So if a method is defined on
`klass` but not on `superklass`, the method could still be defined
somewhere upstream, e.g. in `Object`.
This fix works by avoiding calling `method_defined_within?` with a
module while still fufilling the requirement (checking that the
method is defined withing `superclass` but not is not a generated
attribute method).
4d8ee288 is likely an attempted partial fix for this problem. This
unrolls that fix and properly check the `superclass` as intended.
Fixes #11569.

This commit fixes two regressions introduced in cafe31a078 where
newly created finder methods #second, #third, #forth, and #fifth
caused a NoMethodError error on reload associations and where we
were pulling the wrong element out of cached associations.
Examples:
some_book.authors.reload.second
# Before
# => NoMethodError: undefined method 'first' for nil:NilClass
# After
# => #<Author id: 2, name: "Sally Second", ...>
some_book.first.authors.first
some_book.first.authors.second
# Before
# => #<Author id: 1, name: "Freddy First", ...>
# => #<Author id: 1, name: "Freddy First", ...>
# After
# => #<Author id: 1, name: "Freddy First", ...>
# => #<Author id: 2, name: "Sally Second", ...>
Fixes #13783.

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.

PR #5210 added a Friendship model to illustrate a bug, but in doing so
created a confusing structure because both belongs_to declarations in
Friendship referred to the same side of the join. The new structure
maintains the integrity of the bug test while changing the follower

This caused a bug with the new associations implementation, because now
association conditions are represented as Arel nodes internally right up
to when the whole thing gets turned to SQL.
In Rails 3.2, association conditions get turned to raw SQL early on,
which prevents Relation#merge from interfering.
The current implementation was buggy when a default_scope existed on the
target model, since we would basically end up doing:
default_scope.merge(association_scope)
If default_scope contained a where(foo: 'a') and association_scope
contained a where(foo: 'b').where(foo: 'c') then the merger would see
that the same column is representated on both sides of the merge and
collapse the wheres to all but the last: where(foo: 'c')
Now, the RHS of the merge is left alone.
Fixes #8990

Rename `ActiveRecord::Fixtures` class to `ActiveRecord::FixtureSet`. Instances of this class normally hold a collection of fixtures (records) loaded either from a single YAML file, or from a file and a folder with the same name. This change make the class name singular and makes the class easier to distinguish from the modules like `ActiveRecord::TestFixtures`, which operates on multiple fixture sets, or `DelegatingFixtures`, `::Fixtures`, etc., and from the class `ActiveRecord::Fixture`, which corresponds to a single fixture.

ActiveRecord::ConnectionAdapters::Column#microseconds did an unnecessary
conversion to from Rational to float when calculating the integer number
of microseconds. Some terminating decimal numbers in base10 are
repeating decimal numbers in base2 (the format of float), and
occasionally this causes a rounding error.

Improve the derivation of HABTM join table name to take account of nesting.
It now takes the table names of the two models, sorts them lexically and
then joins them, stripping any common prefix from the second table name.
Some examples:
Top level models
(Category <=> Product)
Old: categories_products
New: categories_products
Top level models with a global table_name_prefix
(Category <=> Product)
Old: site_categories_products
New: site_categories_products
Nested models in a module without a table_name_prefix method
(Admin::Category <=> Admin::Product)
Old: categories_products
New: categories_products
Nested models in a module with a table_name_prefix method
(Admin::Category <=> Admin::Product)
Old: categories_products
New: admin_categories_products
Nested models in a parent model
(Catalog::Category <=> Catalog::Product)
Old: categories_products
New: catalog_categories_products
Nested models in different parent models
(Catalog::Category <=> Content::Page)
Old: categories_pages
New: catalog_categories_content_pages
Also as part of this commit the validity checks for HABTM assocations have
been moved to ActiveRecord::Reflection One side effect of this is to move when
the exceptions are raised from the point of declaration to when the association
is built. This is consistant with other association validity checks.

If a model belongs_to two associations with the same class, then reset_counters
will reset the wrong counter cache.
Finding the right reflection should use the foreign_key instead, which should
be unique.

is 00:50 GMT+1. Without the quoting, the YAML parser would parse this as 00:50 UTC, into the local time of 01:50 GMT+1. Then, it would get written into the database in local time as 01:50. When it came back out the UTC date from the database and the UTC date of two weeks ago would be compared. The former would be 23:50, and the latter would be 00:50, so the two dates would differ, causing the assertion to fail. Quoting it prevents the YAML parser from getting involved.
