[NETCONF-933] 'commit' sent to devices without 'candidate' capability

Tue, 3 Jan 2023 11:01:09 +0000

Configuration of devices without the 'candidate' capability and only with the 'writable-running' capability fails with an 'operation-not-supported' error because a 'commit' RPC is sent to the device which does not support the RPC.

For example, this is the error message returned for a PUT request to Calix E9:

{
    "errors": {
        "error": [
            {
                "error-tag": "operation-not-supported",
                "error-info": "TransactionCommitFailedException{message=Netconf transaction commit failed, errorList=[RpcError [message=Netconf transaction commit failed, severity=ERROR, errorType=APPLICATION, tag=operation-failed, applicationTag=null, info=null, cause=NetconfDocumentedException{message=RPC during tx failed. Unsupported capability :candidate <bad-element>commit</bad-element>, errorType=PROTOCOL, errorTag=operation-not-supported, errorSeverity=ERROR, errorInfo={}}]]}",
                "error-message": "RPC during tx failed. Unsupported capability :candidate <bad-element>commit</bad-element>",
                "error-type": "protocol"
            }
        ]
    }
}

This appears to be a regression of NETCONF-755.
