-----------------------------------
Summary: [Test] Null can be erroneously passed to filter in
optimistic transaction
Key: IGNITE-592
URL: https://issues.apache.org/jira/browse/IGNITE-592
Project: Ignite
Issue Type: Bug
Reporter: Artem Shutak
Assignee: Yakov Zhdanov
Fix For: sprint-3
For optimsitic transaction filter is applied in
GridCacheTxLocalAdapter.enlistWrite, and there are two issues:
- when put is started from backup node we pass to filter detached entry without
value, so that GridCacheEntry.peek returns null even if we have value locally
- when offheap is enabled then entry is unswapped before it is passed to
filter, but there is a race so that another thread can swap it again before
filter is applied
(GridCacheOffHeapMultiThreadedUpdateSelfTest.testPutWithFilterTx)
