[YANGTOOLS-1471] Fail to process unsupported augment statement

Sat, 31 Dec 2022 13:23:17 +0000

Parsing of a data model with an augment statement with if-feature sub-statement fails if

the feature is not supported
the augment statement targets a node defined with a nested grouping and dependent on the feature

For example, parsing of the following example fails when bar-feature is not supported:

module foo {
  namespace "urn:foo";
  prefix "foo";

  feature bar-feature;

  grouping baz-group {
    container baz;
  }

  grouping bar-group {
    container bar {
      if-feature bar-feature;
      uses baz-group;
    }
  }

  container foo {
    uses bar-group;
  }

  augment "/foo/bar/baz" {
    if-feature bar-feature;
    leaf baz-leaf {
      type string;
    }
  }
}

Parser complains that /foo/bar/baz does not exist but it shouldn't attempt to augment the path:
