Cannot read CSS configuration through netconf/restconf

Both of them should be easy to get (at least theoretically).. For the latter one, we just have to turn on the DEBUG logs for sal.netconf.connector something and read the config DS through RESTCONF or directly manually issue the &lt;get-config&gt; rpc over the SSH session.. And from that we can see what part of config is not valid.. I can try to get this response tomorrow..</p> <p>Yeah, we need netconf - layer data, first the document to see if it is well formed (to a certain whether XML parser is okay). If the XML document is wrong, then we need NormalizedNode dump before it is encoded. If the data is wrong, we'll need to dig deeper...</p> <p>I don't think the CSS netconf endpoint actually uses normalized nodes.. If I recall this correctly, ConfigSubsystemFacade creates the XML according to its internal mapping of created CSS modules and QNames. Not really sure about this I would have to check the implementation.</p> <p>Anyway, thinking about this once over again, is this really a blocker? I mean the CSS is already deprecated in Nitrogen and it still should be able to create modules. The only thing that is broken is that we cannot get the CSS config through loopback connection and maybe also we cannot push the config over the loopback. I am not sure if the latter is guaranteed in Nitrogen anyway..</p> <p>Fair point on NormalizedNodes, but even though CSS is deprecated, it should continue to work – can you capture the output XML, please?</p> <p> Here it is<br/> <span class="nobr"><a href="https://jira.opendaylight.org/secure/attachment/14635/14635_CSS-config" title="CSS-config attached to CONTROLLER-1827">CSS-config^{<img

The problem is that identity value is not treated specially in config-manager-facede-xml's SimpleIdentityRefAttributeWritingStrategy and the same prefix is used as for simple attributes. That code needs to be fixed to declare another namespace and use that for the identity value.</p> <p>This is not a regression in that component, as that bug has been present in the initial code drop done by Maros Marsalek. It is a regression in functionality: you can no longer mount the CSS endpoint as a NETCONF device and expect it to work.</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>&lt;type xmlns:prefix="urn:opendaylight:params:xml:ns:yang:controller:md:sal:binding:v1:codec"&gt;prefix:binding-codec-tree-factory&lt;/type&gt;</pre> </div></div> <p>is clearly wrong: binding-codec-tree-factory has a</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>"urn:opendaylight:params:xml:ns:yang:controller:md:sal:binding"</pre> </div></div> <p>namespace and therefore the line should read something like:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>&lt;type xmlns:prefix="urn:opendaylight:params:xml:ns:yang:controller:md:sal:binding:v1:codec" xmlns:odlident="urn:opendaylight:params:xml:ns:yang:controller:md:sal:binding"&gt;odlident:binding-codec-tree-factory&lt;/type&gt;</pre> </div></div> <p>Something along the lines of completely untested  <a href="https://git.opendaylight.org/gerrit/71808," class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/71808</a> or perhaps some other magic in SimpleIdentityRefAttributeWritingStrategy – but that needs a longer look.</p> <p>Following TSC meeting we decided not to fix this bug </p> Development Rank 0|i03e8f:
