Jeffrey Hagelberg updated ATLAS-991:
------------------------------------
Description:
It is often the case multiple entities get deleted at the same time. The
current delete logic does not compute the delete closure up front, so it is
possible for the processing of a particular Entity to trigger a lower bound
violation in an entity that will be deleted but has not been processed yet.
Here's a simple test that can be added to
GraphBackedMetatadataRepositoryDeleteTestBase to reproduce the issue:
{{monospaced}}
@Test
public void testLowerBoundsIgnoredOnDeletedEntities() throws Exception {
String hrDeptGuid = createHrDeptGraph();
ITypedReferenceableInstance hrDept =
repositoryService.getEntityDefinition(hrDeptGuid);
Map<String, String> nameGuidMap = getEmployeeNameGuidMap(hrDept);
ITypedReferenceableInstance john =
repositoryService.getEntityDefinition(nameGuidMap.get("John"));
String johnGuid = john.getId()._getId();
ITypedReferenceableInstance max =
repositoryService.getEntityDefinition(nameGuidMap.get("Max"));
String maxGuid = max.getId()._getId();
ITypedReferenceableInstance jane =
repositoryService.getEntityDefinition(nameGuidMap.get("Jane"));
String janeGuid = jane.getId()._getId();
//the lower bound constraint on jane.subordinates should not be
enforced since jane is being deleted
deleteEntities(johnGuid, maxGuid, janeGuid);
}
