Remove unused version history

[Marek Slama <ms...@email.cz>]

Hello,

I want to ask if there is any way how to remove unused version history. My 
(incorrect used case)

1.Add versionable node.
2.Remove versionable node without removing version history.

I know it is possible to remove version history when I get version history 
first from node using:
versionHistory = versionManager.getVersionHistory(String absPath);

But if it is omitted I can only find out unused version history nodes but as
they are protected it is not possible to
remove it.

Thanks

Marek

Hi,

ok I see. If version history has at least one regular version I will check 
if node with UUID jrc:versionableUuid exists.
If it does not exist it is orphaned version history and I can remove it by 
removing versions from it (from version history).

If version history has only root version there is now no way how to remove 
it till JCR-3238 is fixed. (root version frozen node
actually does not contain any big data - we use nt:file nodes as versionable
so I am mainly concerned about saving space).
(Our old code was wrong - it created versionable nodes and deleted them 
right before next update without calling checkin.
So it resulted exactly in second case.)

Thanks

Marek

Hi,
"
removing the last regular version of a version history should remove
the version history. See: https://issues.apache.org/jira/browse/JCR-134

however, there's a special case and an open issue, when only a root version
exists for a versionable node. see: https://issues.apache.org/jira/browse/
JCR-3238
