While working on updating Paper Trail for 5.1 compatibility, I noticed
that I was required to pass a second argument to `attribute`. I didn't
intend for this to be the case, as `attribute :foo` is totally
reasonable shorthand for "I want `attr_accessor :foo`, but also have it
work with things like `.attributes` and `ActiveRecord::Dirty`"

Fixes casting of IDs to the data type of the association primary key,
rather than then the data type of the model's primary key. (Tests use a
string primary key on the association, rather than an int.)

9c9fb19 changed the behaviour of the _ids= setters for associations to
raise an AssociationTypeMismatch when unknown IDs are given:
Class: <ActiveRecord::AssociationTypeMismatch>
Message: <"Developer(#43811860) expected, got NilClass(#16732720)">
This restores the original ActiveRecord::RecordNotFound exception with a
much clearer error message:
Class: <ActiveRecord::RecordNotFound>
Message: <"Couldn't find all Developers with 'id': (1, -9999) [WHERE \"contracts\".\"company_id\" = ?] (found 1 results, but was looking for 2)">

Since 9.4, PostgreSQL recommends using `pgcrypto`'s `gen_random_uuid()`
to generate version 4 UUIDs instead of the functions in the `uuid-ossp`
extension.
These changes uses the appropriate UUID function depending on the
underlying PostgreSQL server's version, while maintaining
`uuid_generate_v4()` in older migrations.

This patch brings back the functionality of passing true to the
association proxy. The behavior was deprecated with #20888 and scheduled
for removal in Rails 5.1.
The deprecation mentioned that instead of `Article.category(true)` one
should use `article#reload.category`. Unfortunately the alternative does
not expose the same behavior as passing true to the reader
did. Specifically reloading the parent record throws unsaved changes and
other caches away. Passing true only affected the association.
This is problematic and there is no easy workaround. I propose to bring
back the old functionality by introducing this new reader method for
singular associations.

Should except `:distinct` rather than `:order` for `exists?`

Records fetching order is very important for performance if `limit` is
presented. Should not except the order in the case.
And `exists?` replaces select list to `1 AS one` therefore `:distinct`
is useless (`DISTINCT 1 AS one`). And PostgreSQL raises the following
error if `:distinct` and `:order` are used in the same time.
```
ERROR: for SELECT DISTINCT, ORDER BY expressions must appear in select list

As reported via #26904, there is a regression in how values for
Postgres' HStore column type are being processed, beginning in Rails 5.
Currently, the way that Active Record checks whether or not values need
to be serialized and put into the correct storage format is whether or
not it is a `Hash` object. Since `ActionController::Parameters` no
longer inherits from `Hash` in Rails 5, this conditional now returns
false. To remedy this, we are now checking to see whether the `value`
parameters being passed in responds to a certain method, and then
calling the `serialize` method, except this time with a real Hash
object. Keeping things DRY!
Fixes #26904.

- CollectionAssociation#select was removed in
https://github.com/rails/rails/pull/25989 in favor of
QueryMethods#select but it caused a regression when passing arguments
to select and a block.
- This used to work earlier in Rails 4.2 and Rails 5. See gist
https://gist.github.com/prathamesh-sonpatki/a7df922273473a77dfbc742a4be4b618.
- This commit restores the behavior of Rails 4.2 and Rails 5.0.0 to
allow passing arguments and block at the same time but also deprecates
it.
- Because, these arguments do not have any effect on the output of
select when select is used with a block.
- Updated documentation to remove the example passing arguments and
block at the same time to `CollectionProxy#select`.

- If the attribute is not changed, then update_attribute does not run
SQL query, this effectively means that no change was made to the
attribute.
- This change was made in https://github.com/rails/rails/commit/0fcd4cf5
to avoid a SQL call.
- But the change resulted into `nil` being returned when there was no
change in the attribute value.
- This commit corrects the behavior to return true if there is no change
in attribute value. This is same as previous behavior of Rails 4.2
plus benefit of no additional SQL call.
- Fixes #26593.

When the association is autosaved we were storing the details with
string keys. This was creating inconsistency with other details that are
added using the `Errors#add` method. It was also inconsistent with the
`Errors#messages` storage.
To fix this inconsistency we are always storing with symbols. This will
cause a small breaking change because in those cases the details could
be accessed as strings keys but now it can not.
The reason that we chose to do this breaking change is because `#details`
should be considered a low level object like `#messages` is.
Fix #26499.

I still think that this is something that should be handled in the pg
gem, but it's not going to end up happening there so we'll do it here
instead. Once we bump to pg 0.19 we can pass the encoding to the
`encode` method instead.
This issue occurs because C has no concept of encoding (or strings,
really). The bytes that we pass here when sending the value to the
database will always be interpreted as whatever encoding the connection
is currently configured to use. That means that roundtripping to the
database will lose no information
However, after assigning we round trip through our type system without
hitting the database. The only way that we can do the "correct" thin
here would be to actually give a reference to the connection to the
array type and have it check the current value of the connection's
encoding -- which I'm strongly opposed to. We could also pass in the
encoding when it's constructed, but since that can change independently
of the type I'm not a huge fan of that either.
This feels like a reasonable middle ground, where if we have an array of
strings we simply use the encoding of the string we're given.
Fixes #26326.

If a parent association was accessed in an `after_find` or
`after_initialize` callback, it would always end up loading the
association, and then immediately overwriting the association we just
loaded. If this occurred in a way that the parent's `current_scope` was
set to eager load the child, this would result in an infinite loop and
eventually overflow the stack.
For records that are created with `.new`, we have a mechanism to
perform an action before the callbacks are run. I've introduced the same
code path for records created with `instantiate`, and updated all code
which sets inverse instances on newly loaded associations to use this
block instead.
Fixes #26320.

Previously, if the the association was previously loaded and then
the foreign key changed by itself, a #save call would trigger a
load of the new associated record during autosave. This is unnecessary
and the autosave code (in that case) didn't use the loaded record
anyways.

Strict mode controls how MySQL handles invalid or missing values in
data-change statements such as INSERT or UPDATE. If strict mode is not
in effect, MySQL inserts adjusted values for invalid or missing values
and produces warnings.
```ruby
def test_mysql_not_null_defaults_non_strict
using_strict(false) do
with_mysql_not_null_table do |klass|
record = klass.new
assert_nil record.non_null_integer
assert_nil record.non_null_string
assert_nil record.non_null_text
assert_nil record.non_null_blob
record.save!
record.reload
assert_equal 0, record.non_null_integer
assert_equal "", record.non_null_string
assert_equal "", record.non_null_text
assert_equal "", record.non_null_blob
end
end
end
```
It is inconsistent with other types that only text/blob defaults treated
as an empty string. This commit fixes the inconsistency.

The current behaviour of checking if there is a LEFT OUTER JOIN arel
node to detect if we are doing eager_loading is wrong. This problem
wasn't frequent before as only some pretty specific cases would add
a LEFT OUTER JOIN arel node. However, the recent new feature
left_outer_joins also add this node and made this problem happen
frequently.
Since in the perform_calculation function, we don't have access to
eager_loading information, I had to extract the logic for the distinct
out to the calculate method.
As I was in the file for left_outer_join tests, I fixed a few that had
bugs and I replaced some that were really weak with something that
will catch more issues.
In relation tests, the first test I changed would have failed if it
had validated the hash returned by count instead of just checking how
many pairs were in it. This is because this merge of join currently
transforms the join node into an outer join node, which then made
count do a distinct. So before this change, the return was
{1=>1, 4=>1, 5=>1}.

So this bug is kinda funky. The code path is basically "if we weren't passed an
instance of the class we compose to, and we have a converter, call that".
Ignoring the hash case for a moment, everything after that was roughly intended
to be the "else" clause, meaning that we are expected to have an instance of
the class we compose to. Really, we should be blowing up in that case, as we
can give a much better error message than what they user will likely get (e.g.
`NameError: No method first for String` or something). Still, Ruby is duck
typed, so if the object you're assigning responds to the same methods as the
type you compose to, knock yourself out.
The hash case was added in 36e9be8 to remove a bunch of special cased code from
multiparameter assignment. I wrongly assumed that the only time we'd get a hash
there is in that case. Multiparameter assignment will construct a very specific
hash though, where the keys are integers, and we will have a set of keys
covering `1..part.size` exactly. I'm pretty sure this could actually be passed
around as an array, but that's a different story. Really I should convert this
to something like `class MultiParameterAssignment < Hash; end`, which I might
do soon. However for a change that I'm willing to backport to 4-2-stable, this
is what I want to go with for the time being.
