This code is broken (it should say association_scope.uniq_value rather
than options[:uniq]) but the tests still pass.
I think it is designed to uniq-ify associations using finder_sql.
However, I am about to remove that anyway.

Lets stick with a symbol in join table name, it was removed in
993e1643650b7b0939437f86b7b4cda0d92b0b8f and broke the build.

Commit 3dbedd2 added NOT NULL constraints to timestamps.
Commit fcef728 started to revert this, but was incomplete.
With this commit, 3dbedd2 should be fully reverted and
timestamps will no longer default to NOT NULL.

For instance, running
rails g migration CreateMediaJoinTable artists musics:uniq
will create a migration with
create_join_table :artists, :musics do |t|
# t.index [:artist_id, :music_id]
t.index [:music_id, :artist_id], unique: true
end

Integration's definition of #to_param must override
Conversion's. Otherwise, there is a regression from
3.1 in the behavior of a non-persisted AR::Base instance
which nevertheless has an id.

Prepared statements (prepare/execute/close) were being used unnecessarily
when no bind variables were present, and disabling prepared statement using
prepared_statements:false was principally broken. While bind variables were
correctly substituted with prepared_statements:false, the prepared statement
interface was still used, costing an extra two round trips per query.
In addition to making this behavioral change, I also cleaned up the internals
of exec_stmt and exec_without_stmt so that they behave the same (calling log
and constructing the ActiveRecord::Result in the same way).
Moving the check for binds.empty? to exec_query also will mean that several
code paths explicitly calling exec_without_stmt could be cleaned up to once
again call exec_query instead. I have also left the check for binds.empty? in
exec_stmt, since it is not a private method and could be called directly with
an empty binds array. For the sake of clarity in this patch, I have not made
those changes.
= The previous behavior =
When issuing a Foo.find(1) with prepared_statements:true, the bind variable
is present in the prepared query, and execute shows a value passed:
Connect root@localhost on rails_test
Query SET SQL_AUTO_IS_NULL=0
Statistics
Query SHOW FULL FIELDS FROM `foos`
Query SHOW TABLES LIKE 'foos'
Query SHOW CREATE TABLE `foos`
Prepare SELECT `foos`.* FROM `foos` WHERE `foos`.`id` = ? LIMIT 1
Execute SELECT `foos`.* FROM `foos` WHERE `foos`.`id` = 1 LIMIT 1
Close stmt
Quit
When issuing a Foo.find(1) with prepared_statements:false, the bind variable
has already been removed and substituted with the value, but the prepared
statement interface is used anyway:
Connect root@localhost on rails_test
Query SET SQL_AUTO_IS_NULL=0
Statistics
Query SHOW FULL FIELDS FROM `foos`
Query SHOW TABLES LIKE 'foos'
Query SHOW CREATE TABLE `foos`
Prepare SELECT `foos`.* FROM `foos` WHERE `foos`.`id` = 1 LIMIT 1
Execute SELECT `foos`.* FROM `foos` WHERE `foos`.`id` = 1 LIMIT 1
Close stmt
Quit

AddXXXToYYY/RemoveXXXFromYYY migrations are produced with references
statements, for instance
rails g migration AddReferencesToProducts user:references
supplier:references{polymorphic}
will generate the migration with:
add_reference :products, :user, index: true
add_reference :products, :supplier, polymorphic: true, index: true
