[jira] Created: (JCR-600) Repository does not release all resources
on shutdown
Repository does not release all resources on shutdown
-----------------------------------------------------
Key: JCR-600
URL: http://issues.apache.org/jira/browse/JCR-600
Project: Jackrabbit
Issue Type: Bug
Components: core
Affects Versions: 1.0, 1.0.1, 1.1
Reporter: Marcel Reutegger
Assigned To: Marcel Reutegger
Priority: Minor
When Jackrabbit is shutdown some java.util.Timer threads are still running in the background even though no tasks are scheduled. This prevents the GC from collecting the classes when Jackrabbit is redeployed within a web application.

See http://svn.apache.org/viewvc?view=rev&revision=467292 for the changes. The link should also appear on the "All" and "Subversion Commits" tabs of this page in a short while as the SVN-Jira integration does it's magic.

-----------------------------------
I tried with both a 1.1 with the patches attached, and a fresh svn snapshot from Nov 28th 06, and I still see permgen growing without bounds. The code I use is simply
public void contextInitialized(ServletContextEvent event) {
// set up repository
try {
String rootDirectory = (String) ConfigManager.getEnvironmentEntry("jackrabbit/directory");
String configFile = (String) ConfigManager.getEnvironmentEntry("jackrabbit/configfile");
if (configFile.indexOf("/WEB-INF/") == 0) {
log.debug("loading repository config from web application context root: " + configFile);
URL url = event.getServletContext().getResource(configFile);
InputStream repositoryXml = event.getServletContext().getResourceAsStream(configFile);
RepositoryConfig config = RepositoryConfig.create(repositoryXml, rootDirectory);
repository = new TransientRepository(config);
} else {
repository = new TransientRepository(configFile, rootDirectory);
}
Session session = repository.login(new SystemCredentials());
session.logout();
} catch (Exception e) {
log.error("unable to configure Jackrabbit repository; ", e);
}

[jira] Reopened: (JCR-600) Repository does not release all
resources on shutdown
Posted by "Marcel Reutegger (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/JCR-600?page=all ]
Marcel Reutegger reopened JCR-600:
----------------------------------
You are right. My test didn't involve a login. I simply re-deployed the jackrabbit-server.war.
There is still a commit log thread local which holds a strong reference to a jackrabbit class, preventing the GC from collecting the WebappClassLoader.

-----------------------------------
It still doesn't work. Are there other classes that needs modification in jackrabbit 1.1? I've seen that there are threads used in other classes as well, eg RepositoryImpl, TransientFileFactory, ObservationDispatcher and others.

What operations do you perform before you re-deploy the web application?
It works for me when I do a login, read a couple of items and logout again.

Posted by "Marcel Reutegger (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/JCR-600?page=all ]
Marcel Reutegger resolved JCR-600.
----------------------------------
Resolution: Fixed
Jackrabbit now uses a custom Timer class which wraps the java.util.Timer. When there are no tasks scheduled the wrapped java.util.Timer is canceled which effectively terminates the background thread.

I've done a bit more testing and it does in-fact seem to work properly now, so I guess this issue can be resolved as fixed.
