   Code Block
   [ { "int:interface-B": { "interface": [ { "name": "Interface-B", "address": "10.10.10.200", "subnet-mask": "255.255.255.10" } ] } } ]

   
   

Inconsistencies with Patch Operation

When updating multiple data trees with only leaf nodes

Assuming the following data is in the data base, having one leaf node in each data tree

{
  "first-container": {
    "a-leaf": "a-value"
  },
  "last-container": {
    "x-leaf": "x-value"
  }
}

An update operation is performed on both data trees as follows:

curl --location --request PATCH 'http://localhost:8080/cps/api/v1/dataspaces/testDataspace/anchors/multipleDataTree/nodes?xpath=%2F' --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Authorization: Basic Y3BzdXNlcjpjcHNyMGNrcyE=' --header 'Cookie: JSESSIONID=node0kglnliqz1tzc1g0x6opgrphei0.node0' \
--data '{
  "first-container": {
    "a-leaf": "a-new-value"
  },
  "last-container": {
    "x-leaf": "x-new-value"
  }
}'

On performing a get operation, it is noticed that only first data tree gets updated

[
  {
    "multiple-data-tree:last-container": {
      "x-leaf": "x-new-value"
    }
  },
  {
    "multiple-data-tree:first-container": {
      "a-leaf": "a-value"
    }
  }
]

When updating list node with xpath set as root node xpath "/", returns Status 200 but data is not updated

Assuming the following data is in the databse

{
  "int:interface-A": {
    "domain": "false",
    "host-name": "host",
    "interface": [
      {
        "name": "Interface-A",
        "address": "10.10.10.200",
        "enabled": true,
        "subnet-mask": "255.255.255.0"
      }
    ]
  }
}

When performing update operation with xPath set as root

curl --location --request PATCH 'http://localhost:8080/cps/api/v1/dataspaces/testDataspace/anchors/sample/nodes?xpath=%2F' --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Authorization: Basic Y3BzdXNlcjpjcHNyMGNrcyE=' --header 'Cookie: JSESSIONID=node01ejoiyh1brii5zx8z9mk2r39l1.node0' \
--data '{
  "int:interface-A": {
    "domain": "false",
    "host-name": "New-Host",      		//updated value 
    "interface": [
      {
        "name": "Interface-A",
        "address": "10.10.10.0",   	    //updated value
        "enabled": false,			    //updated value
        "subnet-mask": "255.255.255.0"
      }
    ]
  }
}'

Status 200 OK is returned, but on performing the Get operation it is noticed only the leaf nodes get updated and list node remains as it is.

{
  "int:interface-A": {
    "domain": "false",
    "host-name": "New-Host",
    "interface": [
      {
        "name": "Interface-A",
        "address": "10.10.10.200",
        "enabled": true,
        "subnet-mask": "255.255.255.0"
      }
    ]
  }
}
