I wouldn't expect it to, I'd expect to roll back on an exception, or
commit if not. Perhaps this will help you. I use it in production
code.
##
# This is a transaction context manager. It will ensure that the code

exception

reraised.
# If no exception occurs, the transaction will be committed.
# db is a database connection object.
from contextlib import contextmanager
@contextmanager
def transaction(db):
db.begin()
try:
yield None
except:
db.rollback()
raise
else:
db.commit()
