Commented: (JCR-134) Unreferenced VersionHistory should be deleted automatically.

Oleg Alexeyev commented on JCR-134:
-----------------------------------

IMO, this covers at least the most important use case.

Actually, "node.remove() after all versions (except the root version) have been deleted" is not possible
as the node refers to one of the versions. So, we tried to clean up VH, we used node.remove() and then
VH.removeVersion() for each Version returned by getAllVersions() enumeration except the root one.
This approach works, but leaves VH and root version nodes.

Thanks for approaching this issue! :)

> since the creation of a VersionHistory is triggered by the creation of a mix:versionable node, the
removal should happen automatically, as soon as no references to that version histroy exist anymore.
this is the case, when all mix:versionable nodes (in all workspaces) belonging to that VH are deleted, and
all the versions in the VH are removed i.e. only the jcr:rootVersion is left. At this point, the VH should be
deleted aswell.
