[jira] [Commented] (IGNITE-7770) Ignite Cache 6:
testRandomMixedTxConfigurations failed probably after jsr166 removal
[ https://issues.apache.org/jira/browse/IGNITE-7770?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16387722#comment-16387722 ]
Andrey Kuznetsov commented on IGNITE-7770:
------------------------------------------
There are at least two possible flaky failure scenarios.
1 - Most frequent.
NPE; first {{get()}} in transaction returns {{null}}, this should be impossible due to test code structure.
2 - Less frequent.
Timeout while waiting for {{multithreadedAsync()}} completion.
First, some optimistic transaction commits changed entry with key K and parks forever:
sun.misc.Unsafe.park(Native Method)
java.util.concurrent.locks.LockSupport.park(LockSupport.java:304)
org.apache.ignite.internal.util.future.GridFutureAdapter.get0(GridFutureAdapter.java:177)
org.apache.ignite.internal.util.future.GridFutureAdapter.get(GridFutureAdapter.java:140)
org.apache.ignite.internal.processors.cache.transactions.TransactionProxyImpl.commit(TransactionProxyImpl.java:293)
org.apache.ignite.internal.processors.cache.transactions.TxRollbackOnTimeoutTest$4.run(TxRollbackOnTimeoutTest.java:444)
org.apache.ignite.testframework.GridTestUtils$9.call(GridTestUtils.java:1275)
org.apache.ignite.testframework.GridTestThread.run(GridTestThread.java:86)
This transaction keeps hanging even after its timeout occured.
Next, a bunch of pessimistic transactions also park forever on {{put()}} for the same key K:
sun.misc.Unsafe.park(Native Method)
java.util.concurrent.locks.LockSupport.park(LockSupport.java:304)
org.apache.ignite.internal.util.future.GridFutureAdapter.get0(GridFutureAdapter.java:177)
org.apache.ignite.internal.util.future.GridFutureAdapter.get(GridFutureAdapter.java:140)
org.apache.ignite.internal.processors.cache.GridCacheAdapter$22.op(GridCacheAdapter.java:2390)
org.apache.ignite.internal.processors.cache.GridCacheAdapter$22.op(GridCacheAdapter.java:2388)
org.apache.ignite.internal.processors.cache.GridCacheAdapter.syncOp(GridCacheAdapter.java:4088)
org.apache.ignite.internal.processors.cache.GridCacheAdapter.put0(GridCacheAdapter.java:2388)
org.apache.ignite.internal.processors.cache.GridCacheAdapter.put(GridCacheAdapter.java:2369)
org.apache.ignite.internal.processors.cache.GridCacheAdapter.put(GridCacheAdapter.java:2346)
org.apache.ignite.internal.processors.cache.IgniteCacheProxyImpl.put(IgniteCacheProxyImpl.java:1084)
org.apache.ignite.internal.processors.cache.GatewayProtectedCacheProxy.put(GatewayProtectedCacheProxy.java:886)
org.apache.ignite.internal.processors.cache.transactions.TxRollbackOnTimeoutTest$4.run(TxRollbackOnTimeoutTest.java:442)
org.apache.ignite.testframework.GridTestUtils$9.call(GridTestUtils.java:1275)
org.apache.ignite.testframework.GridTestThread.run(GridTestThread.java:86)
And also there is a number of threads operating normally.
