Konrad Windszus commented on JCRVLT-85:
---------------------------------------
The testcase in https://github.com/apache/jackrabbit-filevault/pull/3/ shows
the wrong behaviour of the package installation.
The following steps are performed there:
# a package is installed containing a referenceable node with a UUID
# the referenceable node is moved (which was installed in step 1)
# the same package is installed again
Instead of throwing a failure the package will just overwrite the moved
referencable node from 2 (although its new location is even outside the filter
rules).
> 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
> Components: Packaging
> 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 to 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.
