import transaction
Something simple:
s = transaction.savepoint()
s.rollback()
Something less so:
s = transaction.savepoint()
s1 = transaction.savepoint()
s.rollback()
...okay, so we can nest savepoints, yay!
>>> s1.rollback()
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File
"lib/python/transaction/_transaction.py", line 682, in rollback
raise interfaces.InvalidSavepointRollbackError
transaction.interfaces.InvalidSavepointRollbackError
That makes sense, since we already rolled back to before it.
Okay:
s = transaction.savepoint()
transaction.commit(1)
s.rollback()
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File
"lib/python/transaction/_transaction.py", line 682, in rollback
raise interfaces.InvalidSavepointRollbackError
transaction.interfaces.InvalidSavepointRollbackError
wtf?
