David Rauschenbach closed JCR-1122.
-----------------------------------
Resolution: Cannot Reproduce
I just noticed that I cannot reproduce this problem from the command-line. It
only fails from within Eclipse. Therefore I have some sort of other issue
interfering.
> JCR2SPI Node.addMixin ignored and not added to ChangeLog
> --------------------------------------------------------
>
> Key: JCR-1122
> URL: https://issues.apache.org/jira/browse/JCR-1122
> Project: Jackrabbit
> Issue Type: Bug
> Components: SPI
> Affects Versions: 1.4
> Reporter: David Rauschenbach
>
> The Node.addMixin(String) method does not result in any state change being
> recorded. A subsequent save then becomes a noop, because there are no
> affected nodes.
> The addMixin method is called on an existing node that does not yet contain a
> jcr:mixinTypes property, so SessionItemStateManager performs
> addPropertyState, and then performs nState.markModified().
> When rootNode (parent of the node used above) save() is called,
> getItemState() is immediately called by save, and returns state.status =
> Status.EXISTING. However there are pending changes, so save falls through and
> calls getChangeLog, which returns an empty log because
> NodeEntryImpl.collectStates returns nothing, because getAllChildEntries also
> returns nothing, not even a propertyEntry for the new transient
> jcr:mixinTypes property.
> Test code:
> final String NODE = "testNode";
>
> Session serverSession = login(repository, creds);
> Node serverRootNode = serverSession.getRootNode();
> Node serverNode = serverRootNode.addNode(NODE,
> "nt:unstructured");
> serverSession.save();
> assertEquals(0, serverNode.getMixinNodeTypes().length);
>
> Session clientSession = login(clientRepository, creds);
> Node clientNode = clientSession.getRootNode().getNode(NODE);
> clientNode.addMixin("mix:referenceable"); <== Doesn't mark
> anything modified
> clientSession.save(); <== Does nothing
> serverNode.refresh(false);
> assertEquals(1, serverNode.getMixinNodeTypes().length); <==
> fails
> I'm using an SPI I implemented, in conjunction with the jcr2spi and spi2jcr
> bridges, coupled with a back-end Jackrabbit in-memory filesystem. So there's
> always the possibility that node or property SPI calls inject errors and
> cause this downstream problem.
