"""``transaction`` module: Exported transaction functions.

"""

#: Default implementation of `~ITransaction`
from transaction._transaction import Transaction
#: Default implementation of `~ISavepoint`
from transaction._transaction import Savepoint
#: A single-threaded `~ITransactionManager`
from transaction._manager import TransactionManager
#: A thread-safe `~ITransactionManager`
from transaction._manager import ThreadTransactionManager

# NB: "with transaction:" does not work under Python 3 because they worked
# really hard to break looking up special methods like __enter__ and __exit__
# via getattr and getattribute; see http://bugs.python.org/issue12022.  On
# Python 3, you must use ``with transaction.manager`` instead.

#: The default transaction manager (a `~.ThreadTransactionManager`). All other functions in
#: this module refer to this object.
