This require makes the dependency even more clear.
In particular we are eager loading the session
store but that does not work if AR is used
outside Rails, this patch is preliminary work
in fixing #7160.

Rename test file so that the test suite matches it, implement `persisted?` for SqlBypass as expected by tests and convert session_id to string before using on queries to get correct quotes on postgresql (avoid casting error).

This reverts commit 0e407a90, reversing
changes made to 533a9f84.

Conflicts:

	activerecord/lib/active_record/connection_adapters/abstract/schema_statements.rb
	activerecord/test/cases/migration_test.rb

Two issues fixed:
1) connection_pool is not defined - needed by SessionStore#drop_table!
and create_table! since c94651f8

2) initialization of connection to the default of AR::Base.connection
only occurred at the singleton level - the instance level method defined
by cattr_accessor did not have this logic

I have found that Rails will take an invalid session ID specified by the
client and materialize a session based on that session ID. This means
that it is possible, among other things, for a client to use an
arbitrarily weak session ID or for a client to resurrect a previous used
session ID. In other words, we cannot guarantee that all session IDs are
generated by the server and that they are (statistically) unique through
time.

The fix is to always generate a new session ID in #get_session if an
existing session cannot be found under the incoming session ID.

Also added new tests that make sure that an invalid session ID is never
materialized into a new session, regardless of whether it comes in via a
cookie or a URL parameter (when :cookie_only => false).

Now you can omit |t| block parameter and all the t. from your migration code, that means, the syntax looks more Rails-3-ish, like the routes DSL and ActionMailer DSL.
Also, this change won't break any of your existing migration files, since the traditional syntax is still available.

updated AR#create! to accept an options hash so the mass-assignment security role can be passed in, also updated the Changelog to mention the change to some of the AR method signatures.

- persisted? is the API defined in ActiveModel
- makes it easier for extension libraries to conform to ActiveModel APIs

Replaced hardcoded SessionStore table creation SQL with calls to ActiveRecord adapter migration methods

Otherwise hardcoded table creation SQL was failing on Oracle database

This reverts commit f4cce71d.

First step to merge Rails and Rack session stores. Rack always expects to receive the SID since it may have different behavior if the SID is nil.

This reverts commit e210895b.
