Hi Kapil Thangavelu!
I dont know of if this is what your after, but here is one way do do
transacts with / without rollback
One simple way of having rollback is to do it with except raising a
flag, then
if the flag gets turned on do whatever is needed to undo the current
action
this can be done recursivly, to rollback a whole sequence of actions
rollback=0
try:
[do stuff foo]
try:
[do stuff bar]
except:
rollback=1
if rollback:
[rollback bar]
except:
rollback=1
if rollback:
[rollback foo]
> hmmm... related question (i think) how does one make a method whose
> effect can't be rolled back?
try:
[do stuff foo]
[do stuff bar]
except:
pass
