leaf-list diff

[pkmuthu83]

The diff API does not seem to give full diffs/annotations while changing order of elements in leaf-list. For ex, if we have leaf-list "testleaf", and the data tree dtree1 has the value [A, B], while the dtree2 has [B, A]. When we do dtree1.diff(dtree2), we get :

         {
        "testleaf": [
          "B"
        ],
        "@testleaf": [
          {
            "yang:operation": "replace",
            "yang:orig-default": false,
            "yang:orig-value": "A",
            "yang:value": ""
          }
        ]
      }

This does not give full idea of the diff, right? The first element A changed B, and second element B changed A.
Shouldn't it be something like below:
{
"testleaf": [
"B",
"A",
],
"@testleaf": [
{
"yang:operation": "replace",
"yang:orig-default": false,
"yang:orig-value": "A",
"yang:value": ""
},
{
"yang:operation": "replace",
"yang:orig-default": false,
"yang:orig-value": "B",
"yang:value": ""
}
]
}

Well, the term diff may be misleading, I suppose. The meaning of diff between data tree A and B is a data tree with operations that, when applied to data tree A, you get data tree B.

Thanks for responding. But, can you please elaborate on how the below diff can be applied to dtree1 to get dtree2 ?

         {
        "testleaf": [
          "B"
        ],
        "@testleaf": [
          {
            "yang:operation": "replace",
            "yang:orig-default": false,
            "yang:orig-value": "A",
            "yang:value": ""
          }
        ]
      }

In short, call lyd_diff_apply_all().
