You are right.
The only thing I could come up with was something like below, using a
decorator instead of a context.
-Matthias
@doTransaction(count = 5)
def storeData():
... store data here ...
def doTransaction(transaction = None, count = 3):
def decorator(func):
def do():
for i in range(1+count):
try:
func()
except:
transaction.abort()
raise
try:
transaction.commit()
except ConflictError:
if i == count:
raise
else:
return
return do
return decorator
