webdav webapp is not relinquishing disk space
Hi, we are using the webdav webapp (jackrabbit-webapp-1.5.5.war) configured
with the FileDataStore. We have noticed that files that are deleted from
WebDAV do not seem to relinquish any disk space on the server.
This page indicates that Garbage collection must be done manually in code:
http://wiki.apache.org/jackrabbit/DataStore
Is this why disk space does not seem to be recovered? Is there a way to
configure the webapp to do this automatically?
Thanks,
Greg Schueler

That would be helpful for others as well... If you like to share this
jsp page, please create a Jackrabbit issue and attach the jsp page
there ('Attach file' / 'Grant license to ASF for inclusion ...'):

Thanks, I have actually just created a simple jsp file to drop in along with
the other .jsps in the webdav webapp that will let the garbage collection be
performed on demand.

Hi,
> what is the simplest solution to invoking the garbage collection?
See http://wiki.apache.org/jackrabbit/DataStore - Running Data Store
Garbage Collection (Jackrabbit 1.x)
The Jackrabbit 1.x example doesn't work with the current Jackrabbit
2.0 (not even when using the snapshot). I will fix that.

Yes

No, currently not.

Ok, for installations that have already been configured to use the
FileDataStore, what is the simplest solution to invoking the garbage
collection? It's not clear to me how I can go about doing that.
Do I have to modify the existing webapp/servlet code to add this custom
service and rebuild it? or is it possible to do this via RMI?

You don't have to use the data store - you can use a bundle
persistence manager only, with eg. blob store option on. The data
store is optimized for the typical content repository case, where
deletions are seldom and things are kept/archived for a long(er) time.

I see, so as it stands the webdav webapp cannot really be used "standalone"
as a simple file based WebDAV repository solution, because it requires
custom code to in actualy delete files?

No, afaik not. You need to add your custom background service/thread
to run garbage collection when needed (eg. every night).
