Subject [jira] Commented: (JCR-1865) Add the Data Store to the Jackrabbit API
Date Wed, 02 Sep 2009 20:00:32 GMT

    [ https://issues.apache.org/jira/browse/JCR-1865?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12750636#action_12750636
] 

Jukka Zitting commented on JCR-1865:
------------------------------------

> Could you provide code examples, and all interfaces required for your solution?

Here's a quick example of how this could work:

    ManagedRepository mr = new ManagedRepositoryImpl(RepositoryConfig.create(...));

    // Accessing the repository through normal JCR API
    Repository  repository = mr.getRepository();
    ...;

    // Getting an administrative session (see the similar Sling API)
    Session admin = mr.loginAdministrative();
    ...;

    // Collecting garbage
    GarbageCollector collector = mr.getGarbageCollector();
    try {
        collector.mark();
        collector.sweep();
    } finally {
        collector.close();
    }

    // Closing the repository
    mr.shutdown();

The advantage of this approach over adding things to JackrabbitSession is that access control
to such admin features becomes a deployment issue, not an authorization issue. We won't need
to extend the JCR access control mechanism with custom privileges like "garbage collection"
or "repository shutdown".

> No, because the user may not want to call sweep()

Good point.

> Currently, the garbage collection is not part of the Jackrabbit API. However, the data
store garbage collection must be used once in a while if the data store is enabled. I propose
to add the required interfaces to the Jackrabbit API. This will also allow to call garbage
collection using RMI.
