[NETCONF-312] ODL always uses edit operation "replace"

Relates — Thu, 14 Dec 2023 23:30:43 +0000

In my testing, ODL is always generating NETCONF <edit-config> requests with operation "replace". According to IETF Draft IETF NETCONF RESTCONF the following is expected:

-------------------------------------------------------+

RESTCONF

NETCONF

-------------------------------------------------------+

OPTIONS	none
HEAD	none
GET	<get-config>, <get>
POST	<edit-config> (nc:operation="create")
POST	invoke an RPC operation
PUT	<edit-config> (nc:operation="create/replace")
PATCH	<edit-config> (nc:operation="merge")
DELETE	<edit-config> (nc:operation="delete")

-------------------------------------------------------+
REFERENCE https://tools.ietf.org/html/draft-ietf-netconf-restconf

As a matter of consequence ODL is currently running into issues, for vendors who have not yet implemented the "replace" operation.

Somehow I believe, this is caused by an incomplete implementation. OpenDaylight already has the "checkItemDoesNotExists()" method implemented. So it should use this information to decide about using the "create" or "replace" method based on using POST or PUT.
