code for Version Purging

@ Jitendera, I tried your solution but got an error

@kautuksahni,

I tried option [1],got an error 'org.apache.jackrabbit.core.NodeImpl cannot be cast to javax.jcr.version.VersionHistory'

'

As mentioned by Jitendera,

Option 1:-

Link:- http://wemcode.wemblog.com/version-purging

would help you in writing a code to do version purging.

//

VersionManager mgr = session.getWorkspace().getVersionManager();

// get version history
    VersionHistory vh = (VersionHistory) node.getParent().getParent();
//  VersionHistory vh = mgr.getVersionHistory(path);
    String id = vh.getIdentifier();
 
//  get the names of the versions
    List<String> names = new LinkedList<String>();
    VersionIterator vit = vh.getAllVersions();
    while (vit.hasNext()) {
        Version v = vit.nextVersion();
        if (!v.getName().equals("jcr:rootVersion")) {
           names.add(v.getName());
        }
    }
        
// remove all versions
    for (String name: names) {
      vh.removeVersion(name);
    }

option 2:- Using CURL

Link:- https://helpx.adobe.com/experience-manager/kb/curl-command-version-purge.html

//

Using cron job, schedule the curl commands [1], and then remove the progress file. The following list explains the various input parameters.

• <cmd>  The value can be "dryrun" OR "purge."  The value "dryrun" helps to preview the purged versions. And, value "purge" launches the purge of the versions on the node that the path defines.
• <maxdays> The maximum age of the version of a node. When the age of a version exceeds this value, it is purged.
• <maxversions> The maximum number of versions to keep for a node. When this number exceeds this value, the oldest versions are purged.
• <path> An absolute path on which the purge is applied.
• <recursive> When purging data, you can choose between performing the operation on one node or on a whole hierarchy by selecting Recursive.

An example of curl command to purge everything except last five versions for the tree/content/geometrixx/en/test  is [2] & [3].

[1]

curl -u <userid>:<password> -f -o progress.txt -d "cmd=<cmd>&maxdays=<maxdays>&maxversions=<maxversions>&path=<path>&recursive=<recursive>" "http://<host>:<port>/etc/versioning/purge.html"

[2]

curl -u admin:admin -f -o progress.txt -d "cmd=purge&maxdays=0&maxversions=5&path=/content/geometrixx/en/test&recursive=true" "http://localhost:4502/etc/versioning/purge.html"

[3]

rm progress.txt

I hope this would help you.

Thanks and Regards

Hi,

Here is the code which does the purging. I have not tested this code. However, it seems quite good.

Here is the configuration doc which explains important attributes needed for purging tool
