to the database, corrupting\nthe source host\u0027s pinning information.\n\nThe root cause is that obj_reset_changes() without recursive\u003dTrue\nonly clears the parent Instance\u0027s _changed_fields set.\noslo.versionedobjects\u0027 obj_what_changed() re-adds any ObjectField\nwhose child object carries its own internal changes, so\nnuma_topology remained dirty and was persisted by\n_save_extra_generic().\n\nFix this by calling obj_reset_changes() with recursive\u003dTrue to also\nclear the child objects\u0027 internal change tracking. On entry, we\nsnapshot which migration-context attrs were already dirty; on exit,\nwe restore the original values and only re-dirty the attrs that were\ndirty before entering the context manager.\n\nThis also resolves the FIXME assertions in test_bug_1894095 where\nthe source host picked up destination CPU pins after a periodic\nresource tracker update.\n\nCloses-Bug: #2163408\n\nAssisted-By: Claude-Code opus 4.6\nChange-Id: I56c9a3dd0081bb40263794130e3b9358765d92cd\nSigned-off-by: René Ribaud \u003crene.ribaud@gmail.com\u003e\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/ee450107feaf1a98779a7a37fa46f3984921568f"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/ee450107feaf1a98779a7a37fa46f3984921568f"}]},"branch":"refs/heads/master"}},"requirements":[],"submit_records":[{"rule_name":"gerrit~DefaultSubmitRule","status":"OK","labels":[{"label":"Verified","status":"MAY","applied_by":{"_account_id":22348,"name":"Zuul","username":"zuul","tags":["SERVICE_USER"]}},{"label":"Code-Review","status":"MAY","applied_by":{"_account_id":8313,"name":"Lajos Katona","display_name":"lajoskatona","email":"katonalala@gmail.com","username":"elajkat","status":"Ericsson Software Technology"}},{"label":"Workflow","status":"MAY"},{"label":"Review-Priority","status":"MAY"}]}],"submit_requirements":[{"name":"Verified","description":"Verified in gate by CI","status":"UNSATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Verified\u003dMAX AND -label:Verified\u003dMIN","fulfilled":false,"status":"FAIL","passing_atoms":[],"failing_atoms":["label:Verified\u003dMAX","label:Verified\u003dMIN"],"atom_explanations":{"label:Verified\u003dMAX":"","label:Verified\u003dMIN":""}}},{"name":"Code-Review","description":"Code reviewed by core reviewer","status":"UNSATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Code-Review\u003dMAX AND -label:Code-Review\u003dMIN","fulfilled":false,"status":"FAIL","passing_atoms":[],"failing_atoms":["label:Code-Review\u003dMAX","label:Code-Review\u003dMIN"],"atom_explanations":{"label:Code-Review\u003dMAX":"","label:Code-Review\u003dMIN":""}}},{"name":"Review-Priority","description":"Review Priority","status":"NOT_APPLICABLE","is_legacy":false,"applicability_expression_result":{"fulfilled":false,"status":"FAIL"},"submittability_expression_result":{"expression":"is:true","fulfilled":true,"status":"NOT_EVALUATED","passing_atoms":[],"failing_atoms":[],"atom_explanations":{}}},{"name":"Workflow","description":"Approved for gate by core reviewer","status":"UNSATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Workflow\u003dMAX AND -label:Workflow\u003dMIN","fulfilled":false,"status":"FAIL","passing_atoms":[],"failing_atoms":["label:Workflow\u003dMAX","label:Workflow\u003dMIN"],"atom_explanations":{"label:Workflow\u003dMAX":"","label:Workflow\u003dMIN":""}}}]}
