Konrad Windszus created JCRVLT-85:
-------------------------------------
Summary: ImportUUIDBehavior.IMPORT_UUID_COLLISION_REMOVE_EXISTING
might lead to removal of nodes which are not overwritten by the package
Key: JCRVLT-85
URL: https://issues.apache.org/jira/browse/JCRVLT-85
Project: Jackrabbit FileVault
Issue Type: Bug
Affects Versions: 3.1.16
Reporter: Konrad Windszus
Currently the DocViewSaxImporter is using the
{{ImportUUIDBehavior.IMPORT_UUID_COLLISION_REMOVE_EXISTING}}
(https://github.com/apache/jackrabbit-filevault/blob/trunk/vault-core/src/main/java/org/apache/jackrabbit/vault/fs/impl/io/DocViewSAXImporter.java#L1010).
According the the JCR Spec
(http://www.day.com/specs/jcr/2.0/11_Import.html#11.8.2%20Remove%20Existing%20Node)
that means the node with the same ID is first removed from the repo (no matter
where it is located), then the new node one is imported with that ID.
That is a problem, if by coincidence the ID 1 is used for node /content/a in
the repository and now you install a package containing /content/b also having
the ID 1.
Then the package would remove the /content/a node from the repository, although
this is not intended.
