[NETCONF-777] Http 500 internal server error when deleting non existing data

Wed, 2 Jun 2021 10:54:24 +0000

Restconf DELETE on non existing netconf device data results in HTTP 500 - internal server error instead of 409. The problem appeared in Silicon release and I believe was introduced in https://git.opendaylight.org/gerrit/c/netconf/+/92446 by ditching the DeleteDataTransactionUtil.checkItemExists in DeleteDataTransactionUtil.deleteData.
For example:
1. We have data some data on ../yang-ext:mount/network-topology:network-topology
2. DELETE ../yang-ext:mount/network-topology:network-topology , works fine, data is deleted and Http 204 is returned.
3. DELETE ../yang-ext:mount/network-topology:network-topology , returns Http 500, instead of 409 as it did in previous releases and as I believe is stated in restconf spec.

I also observed the same thing happening when manipulating(POST/PUT) data to netconf device that is not valid according to schema, I think the problem is this problematic-check which in these cases is never true so this exception is returned and since that exception did not map the DocumentedException.ErrorTag it later results in error code 500.

Steps to reproduce:
download silicon release

./karaf clean
feature:install odl-netconf-topology odl-restconf-nb-rfc8040
start netconf-testtool with md-sal :
- create folder schemaToaster with yang model
- java -jar netconf-testtool-1.13.2-SNAPSHOT-executable.jar --schemas-dir schemaToaster --md-sal true
add testtool to topology-netconf:
- restconf PUT on http://127.0.0.1:8181/rests/data/network-topology:network-topology/topology=topology-netconf/node=testtool with payload:

 {
    "netconf-topology:node" :[ 
    	{
	      "node-id": "testtool",
	      "host": "127.0.0.1",
	      "port": 17830,
	      "username": "admin",
	      "password": "admin",
	      "tcp-only": false,
	      "keepalive-delay": 0,
	      "netconf-node-configuration:schemaless": false
        }
    ]
  }

when device is connected execute restconf DELETE on toaster:toaster via mount point of the device:
DELETE http://127.0.0.1:8181/rests/data/network-topology:network-topology/topology=topology-netconf/node=ru-device/yang-ext:mount/toaster:toaster

You should get Http error code 500 internal-server-error and message :

{
    "errors": {
        "error": [
            {
                "error-type": "application",
                "error-tag": "operation-failed",
                "error-info": "NetconfDocumentedException{message=RPC during tx failed. Data is missing, cannot execute DELETE operation , errorType=PROTOCOL, errorTag=DATA_MISSING, errorSeverity=ERROR, errorInfo={}}",
                "error-message": "Transaction failed"
            }
        ]
    }
}

which is wrong and should be 409.
