Removing content

[ehsavoie]

Hi,
I have a nt:file node with its jcr:content child. When I remove my node
(node.remove()) it is correctly removed but the content is still on my
filesystem :( in the repository/datastore/....
How do I delete the content ?

hi if you are using the datastore
you must start the garbage collector

@see http://wiki.apache.org/jackrabbit/DataStore

It doesn't seem to work :((
Here is my code


session = repository.login(new SimpleCredentials(
          attachment.getWorkerId(), new char[0]));
      Node rootNode = session.getRootNode();
      Node fileNode = rootNode.getNode(attachment.getJcrPath(language));
      Node contentNode = fileNode.getNode(JcrConstants.JCR_CONTENT);
      contentNode.remove();
      fileNode.remove();
      session.save();
      GarbageCollector gc = ((org.apache.jackrabbit.core.SessionImpl) session)
          .createDataStoreGarbageCollector();
      if (gc != null && gc.getDataStore() != null) {
        gc.scan();
        gc.stopScan();
        gc.deleteUnused();
      }

What am I missing ?

(the test on the gc is done because I am using a MemoryDatastore for my JUnit tests)

Hi,

I have updated the wiki page, maybe this is the problem:

"Objects in the data store are only removed when they are not
reachable (that means, objects referenced in the cache or in memory
are not collected)"

To clean the cache, you probably have to close the repository (logout
all sessions) and then log in again. To un-reference objects in memory
you can try calling System.gc() (but this will not always work).

Why do you need to delete the files quickly?

Sounds interesting... Did you write it? Did you consider donating it
to Jackrabbit? You don't have to, but probably it would be interesting
for others as well.

Regards,
Thomas

I want to have online edition of OpenOffice document using Webdav.
I have two version of the same document : the in progress visible to the
edting user, and the stable version which can be seen by the others.
Currently the file is stored on the filesystem, so when a user wants to
use it, I move it to jakrabbit and provide a webdav link to the file.
When the user wants to share his modifications, I overwrite the file on
the filesystem and delete my node.
I think I will have the same duplication issue when I move completly to
Jackrabbit since I will have my working document and my shared document
even when no work is in progress.
