I just tested it and atom swaps are not rolled back if a transaction is retried. (Agent sends are held until a transaction succeeds). On the other hand it has to be before any (ensure a-ref) or similar transaction-associated things within the dosync, as the transaction can apparently abort at such points and the atom might therefore not get bumped unless the swap comes earlier. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
