[JBoss JIRA] Created: (JBCACHE-1423) Call to put(Fqn, Map) where Fqn is passivated leads to out of date data

by Brian Stansberry (JIRA)

Call to put(Fqn, Map) where Fqn is passivated leads to out of date data ----------------------------------------------------------------------- Key: JBCACHE-1423 URL: https://jira.jboss.org/jira/browse/JBCACHE-1423 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Components: Cache loaders, Eviction Affects Versions: 3.0.0.CR1, 2.2.1.CR1 Reporter: Brian Stansberry Assignee: Brian Stansberry Fix For: 2.2.1.GA See JBCACHE-1172 for discussion of core problem; this is a variant of that wherein put(Fqn, Map) doesn't result result in loading data from the cache loader. Result is if the put(...) overwrote a key, the in-memory data in the node has the new value but the old value still exists on disk and node.isDataLoaded() will still return false. When a later request causes JBC to detect that n.isDataLoaded() == false, the old data will be retrieved from the cache loader and will replace the newer correct data. Following test to be added to PassivationTestsBase shows the issue: public void testPutDataMapAfterPassivation() throws Exception { Fqn f = Fqn.fromString("/a"); assert !cache.exists(f); assert !loader.exists(f); Map<Object, Object> input = new HashMap(); input.put("one", "one"); input.put("two", "two"); cache.put(f, input); cache.evict(f); input = new HashMap(); input.put("one", "oneA"); cache.put(f, input); Map data = cache.getRoot().getChild(f).getData(); assertEquals("incorrect # of entries", 2, data.size()); assertEquals("Has key 'one", "oneA", data.get("one")); // FAILS!!! assertEquals("Has key 'two", "two", data.get("two")); } Simple fix is in CacheLoaderInterceptor: change from 'false' to 'true' value of 'allKeys' param passed to loadIfNeeded() by visitPutDataMapCommand(). A more general fix would be to change CacheLoaderInterceptor.loadNode() such that no key/value pair in the map loaded from the cache loader is allowed to override an existing key/value pair in the in-memory node. That could have broader repercussions though, so I intend to fix this the simple way. -- 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: (JBCACHE-1420) LockForChildInsertRemove flag not set for root node

by Krzysztof Sobolewski (JIRA)

LockForChildInsertRemove flag not set for root node --------------------------------------------------- Key: JBCACHE-1420 URL: https://jira.jboss.org/jira/browse/JBCACHE-1420 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 2.2.0.GA Reporter: Krzysztof Sobolewski Assignee: Manik Surtani The lockForChildInsertRemove flag gets propagated to all nodes but the root. The root node is being constructed at least four times, three of which properly extract this flag from Configuration object; the remaining one doesn't because it receives null Configuration (it's the first one created). The thing is that the object returned as the root node to the application is the only one with this flag uninitialized. At this point I saw the stack trace and gave up all hopes of penetrating the initialization logic :) Usually this is no big deal, but I have a test that can reliably blow up in 10 seconds on average (on an old, UP laptop) because of that :) and it scares me... -- 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: (JBCACHE-1408) Optimistic locking + JDBC cache loader + DataSources

by Mircea Markus (JIRA)

Optimistic locking + JDBC cache loader + DataSources ---------------------------------------------------- Key: JBCACHE-1408 URL: https://jira.jboss.org/jira/browse/JBCACHE-1408 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 3.0.0.ALPHA1, 2.2.0.GA Reporter: Mircea Markus Assignee: Manik Surtani CacheStoreInterceptor.handleCommitCommand calls CacheStoreInterceptor.storeInternalState. In the optimistic scenario, this will try to add the version of the node (internal state) to the previously stored nodes (nodes are being called in handlePrepareCommand). The problem is that handleCommitCommand is called in an transaction having the status Status.COMMITTED, and when trying to fetch a Connection, org.jboss.resource.connectionmanager.TxConnectionManager checks for current tx status and throws an exception if running tx is not active. Solution: move the code which stores additional info in handlePrepareCommand. This should also bring important performance gains, as for each node a new DB call is made in order to add the version (see CacheStoreInterceptor.storeInternalState). -- 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
