📝 Walkthrough

Walkthrough

The change adds network modification group deletion APIs, removes stashed study-tree elements during study invalidation, and updates the endpoint documentation to describe the expanded behavior.

Changes

Study invalidation cleanup

Layer / File(s) Summary
Modification group deletion APIs and tests
src/main/java/org/gridsuite/study/server/service/NetworkModificationService.java, src/test/java/org/gridsuite/study/server/service/NetworkModificationServiceTest.java
Adds deletion methods for regular and stashed modification groups. The tests verify URLs, JSON UUID payloads, headers, HTTP methods, and typed responses.
Stashed study-tree cleanup
src/main/java/org/gridsuite/study/server/service/NetworkModificationTreeService.java, src/main/java/org/gridsuite/study/server/service/SupervisionService.java, src/main/java/org/gridsuite/study/server/controller/SupervisionController.java
Removes stashed modifications and node entities before root network invalidation. Updates the Swagger summary for the invalidation endpoint.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to babd2

For studies with multiple root networks, a redundant cleanup failure can leave a later root network loaded rather than invalidated. This should be corrected before merge.

Does a stashed modification exists in a group which contain a non stashed modification in a non stashed node ?
I see that when we stash a node, we call deleteStashedModifications. it's not clear for me i will investigate.

Maybe add a comment in the Supervision Controller here:

@DeleteMapping(value = "/studies/{studyUuid}/invalidate")
@Operation(summary = "Invalidate built nodes and delete root node network")

suggestion:

@DeleteMapping(value = "/studies/{studyUuid}/invalidate")
@Operation(summary = "Invalidate all node tree, clean stashed elements and delete root networks")

this is all modification groups for all notStashedNodes for all root networks.
Then we should rename stashedModificationGroupUuids to notStashedNodesModificationGroupsUuids
the filtering between stashed modification or not stashed ones is not done here and there is no meaning of stashed or not stashed groups in the system.

List<UUID> stashedModificationGroupUuids = networkModificationNodeInfos.stream()
.map(NetworkModificationNodeInfoEntity::getModificationGroupUuid)

I think it's ambiguous. Some network modifications should remain.

Suggested change
// remove all stashed nodes and network modifications
// remove all stashed nodes and stashed network modifications

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Run study-wide stashed-element cleanup once, outside the root-network loop.

invalidateStudy processes every root-network ID, but deleteAllStashedElements(studyUuid) reads all nodes for the study and sends a remote deletion request for all non-stashed groups on each invocation. If a later invocation fails, the per-root catch runs before invalidateStudyRootNetwork, so that root network remains LOADED and is not invalidated. Move the cleanup before the loop, handle its exception separately, and keep the per-root error handling for root-network invalidation.
