FunctionalNonTxBackupOwnerBecomingPrimaryOwnerTest.testPrimaryOwnerChangingDuringRemove random failures ------------------------------------------------------------------------------------------------------- Key: ISPN-6040 URL: https://issues.jboss.org/browse/ISPN-6040 Project: Infinispan Issue Type: Bug Components: Core, Test Suite - Core Affects Versions: 8.1.0.Final Reporter: Dan Berindei Assignee: Galder Zamarreño Priority: Blocker Labels: testsuite_stability Fix For: 8.2.0.CR1 Similar to ISPN-6039, the test failure is caused by the state transfer put happening after the test's remove. In this case, the command types are different, so blocking works correctly. However, when the {{ReadWriteKeyValueCommand}} executes before the state transfer put, it doesn't find any value, and it doesn't commit the entry. This means the key is not added to {{CommitManager}}'s {{tracker}} map, and the state transfer put is allowed to write to it - effectively undoing the remove. {noformat} java.lang.AssertionError: expected:<null> but was:<v0> at org.testng.AssertJUnit.fail(AssertJUnit.java:59) at org.testng.AssertJUnit.failNotEquals(AssertJUnit.java:364) at org.testng.AssertJUnit.assertEquals(AssertJUnit.java:80) at org.testng.AssertJUnit.assertEquals(AssertJUnit.java:88) at org.infinispan.distribution.rehash.NonTxBackupOwnerBecomingPrimaryOwnerTest.doTest(NonTxBackupOwnerBecomingPrimaryOwnerTest.java:194) at org.infinispan.functional.distribution.rehash.FunctionalNonTxBackupOwnerBecomingPrimaryOwnerTest.testPrimaryOwnerChangingDuringRemove(FunctionalNonTxBackupOwnerBecomingPrimaryOwnerTest.java:103) {noformat}
