Clarification on the UUID generation

[Alex Parvulescu <al...@gmail.com>]

Hi,

I have a question about the automatic UUID generation.
I have some code that's not working, based on oak-core only. It's a copy of
JcrUtils.putFile method [0].

The insertion fails with the following exception:
org.apache.jackrabbit.oak.api.CommitFailedException: OakConstraint0021:
/file/jcr:content[[nt:resource]]: Mandatory property jcr:uuid not found in
a new node

So who is supposed to add this information (node uuid)?
And who is doing so right now in the oak jcr layer?

thanks,
alex

hi angela,

Thanks for the clarification. indeed I saw those methods, but overall it
looks like something is missing here.
I followed Michael Duerig's advice and manually added a uuid and the commit
goes through fine.

So I can create my repo based on the plugins that I see in the Jcr class,
then I can try to upload a 'file' which apparently comes in with a set of
node type constraints (the content needs a uuid), but there is no plugin
that takes care of the auto-generated properties, shouldn't there be one?

thanks,
alex

hi alex

there are some 'generete-autocreated-items' methods... some parts of
are located in TreeUtil.autoCreateItems but i don't recall exactly
where it is used.

in any case, jcr:uuid is one of these autocreated properties.
maybe a bug somewhere or some sort of backwards incompatibility.

regards
angela
