WalkthroughThe update changes the logic for traversing parent nodes in a node hierarchy. Instead of halting traversal when encountering an external parent node with no current node, the code now skips that parent and continues searching upward. A TODO comment was added regarding potential edge cases with root nodes and entity resolvers. Changes

257-262: Good improvement to parent traversal logic.The change from
breaktocontinuewhen encountering an external parent node is a logical improvement. This allows the traversal to skip non-selectable external parents while continuing to search for a valid root node higher in the hierarchy, which aligns better with the method's goal of finding a resolution starting point.

Address the TODO regarding unreachable root nodes.
The TODO comment highlights a critical edge case where a root node with an enabled entity resolver might be selected but remain unreachable because no parent can provide the required key. This could lead to invalid query plans.
Please verify if this edge case can occur in practice and consider implementing the suggested integration with the duplicate node selection process. You can run the following script to search for related test cases or similar logic patterns:
🏁 Script executed:
#!/bin/bash
# Search for test cases related to entity resolvers and key provision
echo "Searching for entity resolver tests..."
rg -A 10 -B 5 "entity.*resolver|DisabledEntityResolver" --type go
echo -e "\nSearching for key provision logic..."
rg -A 5 -B 5 "provide.*key|requiresKey" --type go
echo -e "\nSearching for duplicate node selection logic..."
rg -A 10 -B 5 "selectDuplicateNodes|duplicated.*node" --type goLength of output: 67504
Implement handling for unreachable root nodes with enabled entity resolver
The TODO at v2/pkg/engine/plan/datasource_filter_visitor.go (around lines 264–267)
// TODO: there could be a potential situation when we have selected root node with enabled entity resolver,
// but we can't jump to it because no parent could provide a key for it
// Need to consider how to move this logic into the selection process of duplicated nodes maybe?remains unaddressed and no existing tests cover a scenario where:
- a node is marked
IsRootNode && !DisabledEntityResolver - but its ancestor chain cannot provide the required key path (
isSelectedParentCouldProvideKeysForCurrentNodefails all the way to the root) - causing the planner to select an unreachable entry point
To resolve:
• In selectDuplicateNodes (and/or the initial root-selection stage), filter out any IsRootNode && !DisabledEntityResolver candidates when there is no valid parent-to-child key path.
• Add a new unit test in datasource_filter_visitor that constructs a query plan where a root entity is resolvable but disconnected (no key-providing parent) and asserts it is correctly skipped or replaced by an alternate duplicate with a valid key path.
Fix at:
- v2/pkg/engine/plan/datasource_filter_visitor.go, method(s) around root-node discovery and in
selectDuplicateNodes - Add corresponding test in v2/pkg/engine/plan/datasource_filter_visitor_test.go

In v2/pkg/engine/plan/datasource_filter_visitor.go around lines 264 to 267, the
TODO about handling root nodes with enabled entity resolver but no valid parent
key path is unaddressed. Fix this by updating the selectDuplicateNodes function
and/or the root-selection logic to filter out any nodes marked IsRootNode with
DisabledEntityResolver false when no parent can provide the required key path.
Additionally, add a unit test in
v2/pkg/engine/plan/datasource_filter_visitor_test.go that creates a query plan
with such a disconnected root entity and verifies it is skipped or replaced by a
valid duplicate node with a proper key path.
