We need to revisit the bit spreaders we use as well as the way we place nodes on a hash wheel and try and improve on this. Virtual nodes may help as well, although that adds significant complexity to the distribution implementation. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-232) add service to provide key that would map to the same (Specified) node

by Mircea Markus (JIRA)

add service to provide key that would map to the same (Specified) node ---------------------------------------------------------------------- Key: ISPN-232 URL: https://jira.jboss.org/jira/browse/ISPN-232 Project: Infinispan Issue Type: Feature Request Reporter: Mircea Markus Assignee: Manik Surtani background: in order to obtain a hashcode that maps to the current node, the way to go is to generate random keys and pass them to the hashing algorithm until the hash for one of them will match the node. This JIRA is about creating an async service to do that, so that the calling thread won't be blocked while this happens. -------------------- from an email discussion What about adding a service to asynchronously generate and pool a number of ids that map to a certain node (in our use case same node)? Advantage would be that the calling thread won't have to wait until we determine an appropriate value. ----------- -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-472) Stop creating a new instance of Decoder10 per each request

by Galder Zamarreno (JIRA)

Stop creating a new instance of Decoder10 per each request ---------------------------------------------------------- Key: ISPN-472 URL: https://jira.jboss.org/browse/ISPN-472 Project: Infinispan Issue Type: Bug Components: Cache Server Affects Versions: 4.1.0.BETA2 Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 4.1.0.CR1 There's no need for HotRodDecoder to create a brand new instance Decoder10 for each request, this is wasteful. It can easily be an instance variable since a new HotRodDecoder is created for each new incoming connection. For the moment, Decoder10 can just be an instance variable in HotRodDecoder. In the future, as more versions are supported, there'll be a map. -- 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] Created: (ISPN-474) Some maven plugins used in build have undefined versions

Some maven plugins used in build have undefined versions -------------------------------------------------------- Key: ISPN-474 URL: https://jira.jboss.org/browse/ISPN-474 Project: Infinispan Issue Type: Bug Affects Versions: 4.1.0.BETA1 Reporter: Sanne Grinovero Assignee: Sanne Grinovero Priority: Minor I'm currently unable to build the trunk of Infinispan as Maven is attempting to use a SNAPSHOT maven-enforcer-plugin which is defined as available but not available for download.

[JBoss JIRA] Created: (ISPN-447) Asking for a cache that doesn't exists in other nodes freezes Infinispan

by Oswaldo Cavalcanti Dantas Junior (JIRA)

Asking for a cache that doesn't exists in other nodes freezes Infinispan ------------------------------------------------------------------------ Key: ISPN-447 URL: https://jira.jboss.org/browse/ISPN-447 Project: Infinispan Issue Type: Bug Components: Distributed Cache Affects Versions: 4.1.0.BETA1 Reporter: Oswaldo Cavalcanti Dantas Junior Assignee: Manik Surtani Attachments: infinispan-test.zip I'm evaluating some of the clustering possibilities with Infinispan and I might have found a bug introduced somewhere in 4.1.x (no problems occur when repeating the same procedures with 4.0.0.Final). I'll attach a simple maven test case where I isolated the freezing conditions. Basically, after starting a test in debug mode twice with a breakpoint after trying to get a cache that doesn't exist on the first VM, the second freezes with the following stack (more details on the attached InfinispanTest class): Thread [main] (Suspended) Unsafe.park(boolean, long) line: not available [native method] LockSupport.park(Object) line: 158 FutureTask$Sync(AbstractQueuedSynchronizer).parkAndCheckInterrupt() line: 747 FutureTask$Sync(AbstractQueuedSynchronizer).doAcquireSharedInterruptibly(int) line: 905 FutureTask$Sync(AbstractQueuedSynchronizer).acquireSharedInterruptibly(int) line: 1217 FutureTask$Sync.innerGet() line: 218 FutureTask<V>.get() line: 83 DistributionManagerImpl.waitForJoinToComplete() line: 144 NativeMethodAccessorImpl.invoke0(Method, Object, Object[]) line: not available [native method] NativeMethodAccessorImpl.invoke(Object, Object[]) line: 39 DelegatingMethodAccessorImpl.invoke(Object, Object[]) line: 25 Method.invoke(Object, Object...) line: 597 ReflectionUtil.invokeAccessibly(Object, Method, Object[]) line: 170 AbstractComponentRegistry$PrioritizedMethod.invoke() line: 852 ComponentRegistry(AbstractComponentRegistry).internalStart() line: 672 ComponentRegistry(AbstractComponentRegistry).start() line: 574 ComponentRegistry.start() line: 148 CacheDelegate<K,V>.start() line: 291 DefaultCacheManager.createCache(String) line: 446 DefaultCacheManager.getCache(String) line: 409 InfinispanTest.test() line: 61 NativeMethodAccessorImpl.invoke0(Method, Object, Object[]) line: not available [native method] NativeMethodAccessorImpl.invoke(Object, Object[]) line: 39 DelegatingMethodAccessorImpl.invoke(Object, Object[]) line: 25 Method.invoke(Object, Object...) line: 597 FrameworkMethod$1.runReflectiveCall() line: 44 FrameworkMethod$1(ReflectiveCallable).run() line: 15 FrameworkMethod.invokeExplosively(Object, Object...) line: 41 InvokeMethod.evaluate() line: 20 BlockJUnit4ClassRunner.runChild(FrameworkMethod, RunNotifier) line: 76 BlockJUnit4ClassRunner.runChild(Object, RunNotifier) line: 50 ParentRunner$3.run() line: 193 ParentRunner$1.schedule(Runnable) line: 52 BlockJUnit4ClassRunner(ParentRunner<T>).runChildren(RunNotifier) line: 191 ParentRunner<T>.access$000(ParentRunner, RunNotifier) line: 42 ParentRunner$2.evaluate() line: 184 RunBefores.evaluate() line: 28 BlockJUnit4ClassRunner(ParentRunner<T>).run(RunNotifier) line: 236 JUnit4TestClassReference(JUnit4TestReference).run(TestExecution) line: 46 TestExecution.run(ITestReference[]) line: 38 RemoteTestRunner.runTests(String[], String, TestExecution) line: 467 RemoteTestRunner.runTests(TestExecution) line: 683 RemoteTestRunner.run() line: 390 RemoteTestRunner.main(String[]) line: 197 Probably there is a simpler, more elegant way to test this condition (one that could be used in a official test case) but this was the fastest way for me to reproduce the bug without going too deep in the Infinispan internals. -- 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
