Introduce transaction_joinable flag to mark that the fixtures transaction can't joined, a new savepoint is required even if :requires_new is not set. Use :requires_new option instead of :nest. Update changelog.

[#383 state:committed]

Don't use the transaction instance method so that people with has_one/belongs_to :transaction aren't fubared

[#1551 state:committed]
Signed-off-by: NJeremy Kemper <jeremy@bitsweat.net>

Rename ActiveRecord::Base#transaction's :force option to :nest. Improve documentation for nested transactions.

Improve documentation for DatabaseStatements#transactions and AbstractAdapter#transactional_fixtures, especially with regard to support for nested transactions.

Wrap overview documentation for ActiveRecord::Transactions::ClassMethods so that it's easier to read in a text editor with word wrapping enabled.

Add overview description for ActiveRecord::Transactions, telling the reader to look at ClassMethods instead.

Previously this would have committed the transaction but not carried out save or destroy operation.

 * Generate Reader and Writer methods which cache attribute values in hashes.  This is to avoid repeatedly parsing the same date or integer columns.
 * Move the attribute related methods out to attribute_methods.rb to de-clutter base.rb
 * Change exception raised when users use find with :select then try to access a skipped column.  Plugins could override missing_attribute() to lazily load the columns.
 * Move method definition to the class, instead of the instance
 * Always generate the readers, writers and predicate methods.

 Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections.

 PostgreSQL: introduce allow_concurrency option which determines whether to use blocking or asynchronous #execute. Adapters with blocking #execute will deadlock Ruby threads. The default value is ActiveRecord::Base.allow_concurrency.
 r4648@asus:  jeremy | 2006-06-19 13:08:40 -0700
 Pass the default allow_concurrency when instantiating new connections.

 Break out concurrent transaction tests and run them for PostgreSQLAdapter only (need to fork or system('some_test_script') for the other adapters)

 Row locking. Provide a locking clause with the :lock finder option or true for the default "FOR UPDATE".
