Recovery not fully triggered when distributed transaction falls down at prepare phase of 2PC

    XMLWordPrintable

    Details

      Description

      It looks like recovery process is not fully triggered on a distributed transaction when the transaction falls down at prepare phase of 2PC. In the new crash recovery tests over propagated transactions only one of two servers recovers from the crash, but the other keeps an unfinished tx in its tx log.

      It corresponds to prepareHaltClient and prepareHaltServer test methods of org.jboss.as.test.jbossts.crashrec.txpropagation.TxPropagationCrashRecoveryTestCase, see JBQA-2604 for general description of the new tests. The prepareHaltClient test crashes the server which initiated the transaction, while as the prepareHaltServer test crashes the second server.

      The tests are written against EAP6.x branch, so for reproducing this it is needed a built server from the 7.1 branch of AS7.

      Steps to reproduce.
      1. git clone -b as7 git://git.app.eng.bos.redhat.com/jbossqe/eap-tests-transactions.git
      2. cd eap-tests-transactions
      3. git checkout tx_propag_crashrec_tests
      4a. mvn clean verify -Dtest=TxPropagationCrashRecoveryTestCase#prepareHaltClient -Djboss.dist=<path to jboss-as-7.1.3.Final-SNAPSHOT>
      or
      4b. mvn clean verify -Dtest=TxPropagationCrashRecoveryTestCase#prepareHaltServer -Djboss.dist=<path to jboss-as-7.1.3.Final-SNAPSHOT>

      The logs of prepareHaltClient run attached to this jira.
