[JBoss JIRA] (JBTM-1602) Determine why 4 locks acquired in LockManager.propagate

by Michael Musgrove (JIRA)

[ https://issues.jboss.org/browse/JBTM-1602?page=com.atlassian.jira.plugin.... ] Michael Musgrove commented on JBTM-1602: ---------------------------------------- The test that originally showed up the race condition (org.jboss.jbossts.qa.junit.testgroup.TestGroup_jtsremote#JTSRemote_DistributedHammerTest2) used to fail on average after about 20 runs so 1000 runs with your changes certainly looks to have fixed the original issue.

by Mark Little (JIRA)

[ https://issues.jboss.org/browse/JBTM-1602?page=com.atlassian.jira.plugin.... ] Mark Little commented on JBTM-1602: ----------------------------------- Reverted some of the optimisations and re-tested against jtsremote qa test runs. Added to run-tests.xml: <target name="foobar">  <junit-tests tests="jtsremote"/> </target> (Will not commit this change - it's only to test these changes locally.) Then run: ant -f run-tests.xml foobar 1000 times, with the output below from each run: Buildfile: /Users/marklittle/github/narayana/qa/run-tests.xml foobar: [echo] Running junit test group jtsremote from basedir=/Users/marklittle/github/narayana/qa [junit] Running org.jboss.jbossts.qa.junit.testgroup.TestGroup_jtsremote [junit] Tests run: 9, Failures: 0, Errors: 0, Time elapsed: 75.86 sec BUILD SUCCESSFUL Total time: 1 minute 17 seconds > Determine why 4 locks acquired in LockManager.propagate > ------------------------------------------------------- > > Key: JBTM-1602 > URL: https://issues.jboss.org/browse/JBTM-1602 > Project: JBoss Transaction Manager > Issue Type: Task > Security Level: Public(Everyone can see) > Components: Transaction Core > Affects Versions: 5.0.0.M2 > Reporter: Mark Little > Assignee: Mark Little > -- This message is automatically generated by JIRA.

[JBoss JIRA] (JBTM-1608) Reconsider whether all STLA 2PC methods need context associating (for TXOJ)

by Mark Little (JIRA)

Mark Little created JBTM-1608: --------------------------------- Summary: Reconsider whether all STLA 2PC methods need context associating (for TXOJ) Key: JBTM-1608 URL: https://issues.jboss.org/browse/JBTM-1608 Project: JBoss Transaction Manager Issue Type: Task Security Level: Public (Everyone can see) Components: JTS, STM, Transaction Core Affects Versions: 5.0.0.M2 Reporter: Mark Little Assignee: Mark Little All of the ServerTopLevelAction 2PC methods have local context association commented out, since it's not strictly needed in the JTS (a Resource is implicitly associated with a single transaction). It's not invalid either though, but we commented it out years ago. It's been added back for the rollback method. Check to see if it needs to be added back to all methods for consistency. May be needed for distributed STM. -- This message is automatically generated by JIRA.

by Mark Little (JIRA)

[ https://issues.jboss.org/browse/JBTM-1602?page=com.atlassian.jira.plugin.... ] Mark Little commented on JBTM-1602: ----------------------------------- This may also relate to https://issues.jboss.org/browse/JBTM-648 in so much as the issue could have been masked by the use of our own locking implementation in the past which was less optimal (e.g., reduced the chance of race conditions.) > Determine why 4 locks acquired in LockManager.propagate > ------------------------------------------------------- > > Key: JBTM-1602 > URL: https://issues.jboss.org/browse/JBTM-1602 > Project: JBoss Transaction Manager > Issue Type: Task > Security Level: Public(Everyone can see) > Components: Transaction Core > Affects Versions: 5.0.0.M2 > Reporter: Mark Little > Assignee: Mark Little > -- This message is automatically generated by JIRA.

[JBoss JIRA] (JBTM-1602) Determine why 4 locks acquired in LockManager.propagate

by Mark Little (JIRA)

[ https://issues.jboss.org/browse/JBTM-1602?page=com.atlassian.jira.plugin.... ] Mark Little commented on JBTM-1602: ----------------------------------- I'm not convinced this change is the right one to make or has been applied consistently to the rest of the class. I'll take a look at the test case you had which reproduced the problem and revert some of the optimisations we've applied over the years to LockManager to reduce contention and which have probably introduced this vulnerability. > Determine why 4 locks acquired in LockManager.propagate > ------------------------------------------------------- > > Key: JBTM-1602 > URL: https://issues.jboss.org/browse/JBTM-1602 > Project: JBoss Transaction Manager > Issue Type: Task > Security Level: Public(Everyone can see) > Components: Transaction Core > Affects Versions: 5.0.0.M2 > Reporter: Mark Little > Assignee: Mark Little > -- This message is automatically generated by JIRA.
