[JBoss JIRA] Created: (JBCACHE-1585) JBossCache eviction thread creating a Timer without making the new thread a daemon thread

by Mats Henrikson (JIRA)

JBossCache eviction thread creating a Timer without making the new thread a daemon thread ----------------------------------------------------------------------------------------- Key: JBCACHE-1585 URL: https://jira.jboss.org/browse/JBCACHE-1585 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 1.4.1.SP13 Reporter: Mats Henrikson Assignee: Manik Surtani There is a problem where the class org.jboss.cache.eviction.RegionManager.EvictionTreeCacheListener.cacheStarted(), line 499: {code} evictionThread_ = new Timer(); {code} Since the new Timer() is created without telling it that it is a daemon thread this Timer thread will actually cause the JVM to not exit when the main() method of the application finishes - it makes it necessary to call System.exit() to shut the JVM down. Since this is the thread that periodically runs the specified eviction policy there is no need for it to cause the JVM to stay running - it's up to the developer to say if the JVM should stay running or not, not JBossCache. The line should be changed to something like: {code} evictionThread_ = new Timer(true); {code} in order to specify that this is a daemon thread. (At the same time it would also be good if the Timer is passed a thread name like for instance "JBossCache Eviction Thread".)

[JBoss JIRA] Created: (JBCACHE-1596) Initial state transfer with more than 200, 000 nodes deadlock on eviction queue

[JBoss JIRA] Created: (JBCACHE-1582) ExpirationAlgorithm doesn't evict nodes that have been created in a long Tx

by Nicolas Filotto (JIRA)

ExpirationAlgorithm doesn't evict nodes that have been created in a long Tx ---------------------------------------------------------------------------- Key: JBCACHE-1582 URL: https://jira.jboss.org/browse/JBCACHE-1582 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Components: Eviction Affects Versions: 3.2.5.GA Reporter: Nicolas Filotto Assignee: Manik Surtani Attachments: TestExpirationAlgorithm.java, TestExpirationAlgorithm.java I noticed that I had a memory leak in my application when I use the ExpirationAlgorithm (maybe this bug happens with other algorithms) some nodes were never evicted. After a deeper investigation, I noticed that the no EvictionEntry was created for those nodes since the method getExpiration returns null (which also means that cache.peek(fqn, false) returns null). I finally found the problem, that is because if the Expiration Thread wakes up before that the related Tx is committed, it won't find the node into the cache so it will considered it as removed but in fact it is just because the Tx has not yet been committed. This has for consequence that the node will never be evicted and thus create a memory leak. Please find the related unit test as attached file. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Commented: (PCACHE-85) Detach leaves internal Fqns lying around

by Thomas Strecker (JIRA)

[ https://issues.jboss.org/browse/PCACHE-85?page=com.atlassian.jira.plugin.... ] Thomas Strecker commented on PCACHE-85: --------------------------------------- I have followed the issue closely and evaluated my options, but unfortunately I cannot use the workarounds presented here. Another suggested workaround was to manually detach the internal Fqns. However, I cannot find a way to achieve that. Are there any suggestions? > Detach leaves internal Fqns lying around > ---------------------------------------- > > Key: PCACHE-85 > URL: https://issues.jboss.org/browse/PCACHE-85 > Project: JBoss POJO Cache > Issue Type: Bug > Security Level: Public(Everyone can see) > Affects Versions: 3.0.0.GA > Reporter: Galder Zamarreño > Assignee: Galder Zamarreño > Attachments: AttachDetachStressTest.java > > > Detach leaves around internal Fqns even though they've been nulled the objects stored within them. > This means that in apps that do a fair bit of attach/detach, the memory consumption keeps growing up. > We should do a better cleanup process on detach. > Please find attached a simple test that needs further enhancing. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBCACHE-1595) PARENT column needs an index

by Bill Middleton (JIRA)

PARENT column needs an index ---------------------------- Key: JBCACHE-1595 URL: https://issues.jboss.org/browse/JBCACHE-1595 Project: JBoss Cache Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Cache loaders Affects Versions: 3.2.5.GA Environment: Oracle, other relations databases Reporter: Bill Middleton Assignee: Manik Surtani We've struggled here for some time using JBC and recently got some help from a database expert. He noticed correctly that our implementation does a lot of selectChildNames(), but that there exists no index on PARENT column in the database, only on the FQN column. Creating one vastly improved our implementation. I wonder if it's been considered as a default functionality before in JBC? I suspect that there are a number of TimeoutException issues which are currently open here which could be resolved by implementing this. Note that even simple hot-start times (where we dont actually fetch children at all in our app) dropped dramatically. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
