appengine 1.6.4 datanucleus-appengine-2.0.0 datanucleus cache 3.0.1

こんにちは、みんな

datanucleusレベル2キャッシュを使用して、読み取りクエリから古いデータが返されます。

私の永続的な構成にはキャッシュ設定がないため、ドキュメントからはデフォルト設定を使用しています。

問題

ステップ1：TX1で、エンティティMerchantPromotion（5）で単純なマージを実行します。

結果1：データストアビューアは、エンティティが正しく更新されたことを示します。

ステップ2：TX2で、エンティティMerchantPromotion（5）の読み取りを実行します。

結果2：返されるデータは、変更されたデータではなく、事前にマージされたデータです。

レベル2キャッシュがNONEに設定されている場合、操作は正常に機能するため、レベル2キャッシュに関連しているようです。

DNトレースが添付されます。

助けていただければ幸いです。

アプリエンジンでdatanucleusを使用してjpaを使用しています。クエリ「DELETE FROM SOMETABLENAME a」を実行し、後でその ID でオブジェクトをフェッチしても、キャッシュはそれを返します!

私のpersistance.xmlファイルに追加すると、問題が修正されました。

現在のライブラリのバージョンは

datanucleus-api-jdo-3.1.1 
datanucleus-api-jpa-3.1.1
datanucleus-core-3.1.1

スタック トレースの一部

ObjectManagerImpl.getObjectFromCache(Object) line: 5030 
ObjectManagerImpl.findObject(Object, boolean, boolean, String) line: 3282   
JPAEntityManager.find(Class<T>, Object, LockModeType, Map<String,Object>) line: 358 
JPAEntityManager.find(Class, Object) line: 256

これは過去 6 か月以内に発生した更新ですか? このバージョンに更新する前は、すべての単体テストは問題ありませんでした。キャッシュを無効にした後、すべてが再びチェックアウトされます。アプリ エンジンは新しい設定を尊重しますか?
