PR Summary

Now, 'logical controls' becomes an asynchronous computation, just like the others (loadflow, state estimation, etc).

Works with gridsuite/gridstudy-app#4257 and a up-to-date state-estimation-server.

Walkthrough

The study server now runs logical-controls computations through dedicated endpoints and services. It stores result UUIDs, processes logical-controls events, reports status, invalidates results after parameter updates, and supports result deletion.

Changes: Logical Controls

Layer / File(s) Summary
Result identity and persistence
src/main/java/org/gridsuite/study/server/dto/*, src/main/java/org/gridsuite/study/server/networkmodificationtree/entities/RootNetworkNodeInfoEntity.java, src/main/java/org/gridsuite/study/server/service/RootNetworkNodeInfoService.java, src/main/java/org/gridsuite/study/server/service/StudyService.java, src/main/resources/db/changelog/*
Adds logical-controls metadata, result UUID storage, a database column, and computation-status reporting.
Run, status, and result flow
src/main/java/org/gridsuite/study/server/controller/logicalcontrols/LogicalControlsController.java, src/main/java/org/gridsuite/study/server/service/logicalcontrols/*, src/main/java/org/gridsuite/study/server/service/ConsumerService.java, src/main/java/org/gridsuite/study/server/notification/NotificationService.java, src/main/resources/config/application.yaml, src/main/java/org/gridsuite/study/server/controller/stateestimation/StateEstimationController.java, src/main/java/org/gridsuite/study/server/service/stateestimation/*
Adds run, stop, result, and status endpoints; computation-server requests; event consumers; and notifications. Removes the former state-estimation logical-controls path.
Invalidation and result cleanup
src/main/java/org/gridsuite/study/server/dto/InvalidateNodeInfos.java, src/main/java/org/gridsuite/study/server/dto/RemoteDeletionInfos.java, src/main/java/org/gridsuite/study/server/repository/rootnetwork/RootNetworkNodeInfoRepository.java, src/main/java/org/gridsuite/study/server/service/RootNetworkNodeInfoService.java, src/main/java/org/gridsuite/study/server/service/SupervisionService.java, src/main/java/org/gridsuite/study/server/service/stateestimation/StateEstimationService.java
Passes result UUIDs through invalidation and deletion data. Invalidates logical-controls results after parameter updates. Adds result deletion and dry-run counting.
Integration validation
src/test/java/org/gridsuite/study/server/LogicalControlsTest.java, src/test/java/org/gridsuite/study/server/*Test.java, src/test/java/org/gridsuite/study/server/service/stateestimation/StateEstimationServiceTest.java
Tests logical-controls execution, messaging, retrieval, stopping, invalidation, failure handling, deletion, and updated computation-status responses.

Suggested reviewers: klesaulnier

Priority: Normal

Merge Risk: Low · previous review 1b304

A failed rerun can leave result and status requests pointing to a deleted result, and converting node information can lose a saved result ID. These bounded risks warrant owner acceptance or a fix before merging.

Persist the new result before best-effort cleanup.

If the previous DELETE succeeds and the new runLogicalControls request fails, updateComputationResultUuid is not called. The node keeps the deleted UUID, so result and status requests can propagate 404 responses.

Do not only move deletion after the update. A deletion exception can roll back the surrounding transaction and leave the node pointing to the old UUID. Run the new computation, store its UUID, and handle cleanup failure without aborting the transaction.
