[jira] [Commented] (IGNITE-3537) Add tests checking that data structures work inside user transactions

["Semen Boikov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-3537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15754539#comment-15754539 ] 

Semen Boikov commented on IGNITE-3537:
--------------------------------------

Some more details:
implementation of ignite data structures internally uses special system caches, need make sure that transaction on these system caches do not intersect with transactions stared by user. Test pseudo-code (also GridCachePartitionedAtomicSequenceTxSelfTest.testIsolation can be used as example):
{noformat}
        IgniteAtomicLong atomicLong = ignite.atomicLong();
        
        try (Transaction tx = ignite(0).transactions().txStart()) {
            atomicLong.incrementAndGet();

            cache.put(1, 1);

            tx.rollback();
        }
        
        assertEquals(1L, atomicLong.get()); // Tx was rolled back, but IgniteAtomicLong increment should be committed.
{noformat}

Need add tests for IgniteSet, IgniteQueue, IgniteSemaphore, IgniteLock, IgniteCountDownLatch, IgniteAtomicStamped, IgniteAtomicReference, IgniteAtomicLong. We already have test classes for all these data structures (e.g. IgniteAtomicLongApiAbstractSelfTest), need just add new testcases into these class.

> Need create tests to check that Ignite data structures work inside user transaction. Now data structures should use independent transactions, test should jus check that there are no exceptions.
