Can not invoke zero argument RPC exposed by a Netconf device mounted on ODL using Restconf

Bug Verified Done Vaclav Demcak Balaji Varadaraju Tue, 9 Jun 2015 17:48:14 +0000 Wed, 17 Jun 2015 18:29:08 +0000 Wed, 17 Jun 2015 18:29:08 +0000 Lithium restconf 0 4 <p>Wanted to add this is a zero input RPC but it provides some output. So looks like we have an error while processing the output.</p> <p>I assume it's getting into the RestconfImpl#invokeRpc method that takes the "noPayload" string. </p> <p> final ContainerSchemaNode rpcDataSchemaNode =<br/> SchemaContextUtil.getRpcDataSchema(schemaContext, <br/> rpc.getOutput().getPath());<br/> resultNodeSchema = rpcDataSchemaNode.getDataChildByName(<br/> result.getResult().getNodeType());</p> <p>It seems that resultNodeSchema is null. However I don't understand why this code is needed when the RpcDefinition was already found earlier. Why doesn't it just use that RpcDefinition for resultNodeSchema? The NormalizedNodeXmlBodyWriter and NormalizedNodeJsonBodyWriter check for schemaPath instanceof RpcDefinition and use the output schema path.</p> <p>Seems as left-over of some refactor:</p> <p>first call:<br/> final ContainerSchemaNode rpcDataSchemaNode =<br/> SchemaContextUtil.getRpcDataSchema(schemaContext, <br/> rpc.getOutput().getPath());</p> <p>Should return rpc/output container</p> <p>Second call: tries to look up output in rpc/output container instead of RPC.</p> <p>So it seems the resultNodeSchema should be simply = rpc.getOutput()</p> <p> resultNodeSchema = rpcDataSchemaNode.getDataChildByName(<br/> result.getResult().getNodeType());</p> <p>Will try to replicate and verify.</p> <p>Actually when I tried it with a no-input rpc with output, the code path was not thru the "noPayload" method but thru the NormalizedNodeContext ("with payload") method and getData() was null. The rpc worked correctly.</p> <p>I'll debug it with Bala to see the code path for his failed mounted rpc.</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/22573/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/22573/</a></p> Duplicate CONTROLLER-1242 Development External issue ID 3650 External issue URL Issue Type ODL SR Target Milestone Priority Rank 0|i02q47:
