Subject [jira] [Commented] (IGNITE-2969) Optimistic transactions support in deadlock detection

Semen Boikov commented on IGNITE-2969:
--------------------------------------

Andrey,

Looked at your changes, I think you need implement proper synchronization in GridDhtTxPrepareFuture
between future timeout and 'normal' future processing. Is it possible now that PrepareTimeoutObject
completed future, but some other thread still continue to process GridDhtTxPrepareRequest/GridDhtTxPrepareResponses?
(the same for GridNearOptimisticTxPrepareFuture).
