Cédric Damioli commented on JCR-134:
------------------------------------
And about the two other points :
- should the VH be deleted on node.removeMixin("mix:versionable") ? would it be safe ?
- may a Node be versionable in a workspace and not in another one ? I think the spec allows
it (it doesn't actually forbid it). But I need confirmation.
So the only way to do this is IMHO the following algorithm :
- when removing a Version, if this is the last version (only the jcr:rootVersion is left),
and there is no references to the jcr:rootVersion, one can remove the VH
- when removing a Node, if it is versionable, and references the jcr:rootVersion (ie have
never been checked in) and there is no other references to the VH (in others workspaces),
then delete the VH
- when removing the mix:versionable, either delete directly the VH (see my first question
in this post), either check if there is only the jcr:rootVersion left, and then delete the
VH.
WDYT ?

> 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.
