Précisions sur une relation bidirectionnelle 1 -- 0..1
by Tony Chemit 17 Sep '14

17 Sep '14

Hello, Je voudrais avoir quelques précisions sur une relation bidirectionnel 1 -- 0..1 J'ai dans le modèle : Section (0..1 -- 0.*) Catch Brancheline (0..1 -- 0.1) Catch Dans le cadre de la relation Section, l'information en base est portée par la table Catch ce qui est logique : plusieurs Catch peuvent être rattaché à une Section. Par contre pour la relation BrancheLine l'information est portée par la table BrancheLine, ce qui peut se comprendre aussi car on ne peut avoir qu'un seul Catch associé. Cependant, je voudrais que l'information soit portée par la table Catch et non pas BrancheLine. Est-ce possible au niveau d'hibernate ? Je vois que le mapping généré est : (dans BrancheLine) <many-to-one name="catch" class="fr.ird.observe.entities.longline.CatchImpl" column="catch" node="catch/@topiaId"/> (dans Catch) <many-to-one name="branchline" class="fr.ird.observe.entities.longline.BranchlineImpl" column="branchline" node="branchline/@topiaId"/> Merci, tony.

Fetch mathematics
by Eric Chatellier 26 Aug '14

26 Aug '14

Bonjour, Pour faire un retours sur la performance (ou non performance des fetch), voici quelque stats sur un cas rapide sur PostgresSQL, mais très lent sur Sql Server. Le problème de lenteur n'est pas le point ici, mais plutot le volume de données qui transit. Pour la volumétrie de la requete, on a: - 1 Mail (23 champs) - 4 Pièces jointes (9 champs) - 56 Ligne d'historique (7 champs) - 11 autres entité de cardinalité 1 (EtatAttente, DemandStatus...) La requete executée est la suivante: http://forge.codelutin.com/issues/5655#note-3 Elle retourne environ 224 lignes (soit le produit cartésien de 1 * 4 * 56) L'ensemble des champs représente 131 colonne. Soit un ResultSet composé de 29344 élément. Donc 29344 pour afficher un seul élément. À titre de comparaison, la même fonctionnalité en 3 requêtes aurait retourné 1 * 115 = 115 (email + relation 0..1 avec fetch) 4 * 9 = 36 (attachments) 56 * 7 = 392 (historique) Soit un result set de 543 éléments, mais en 3 requetes. Le produit cartésien augmente beaucoup la taille donc je me demande si c'est si performant que ca, ou que cela doit être nuancé par la volumétries des données. Ne faudrait-il pas laisser les fetch pour les relations (0..1) et effectuer d'autres requetes pour les autres relations (2..*) ? -- Éric Chatellier - www.codelutin.com - 02.40.50.29.28

Pool C3p0 non fermé

This probably means that an application using c3p0 was undeployed, but not all PooledDataSources were closed prior to undeployment. This may lead to resource leaks over time. Please take care to close all PooledDataSources. J'ai trouvé un gros gros hack qui fonctionne: http://stackoverflow.com/a/7472386 ce qui semble bien démontrer qu'il y a un problème quelque part avec Topia/Hibernate (c3p0?).

Composition et cascade
by Eric Chatellier 20 May '14

20 May '14

Bonjour, Dans la PJ, les relations utilisent des compositions, mais les cascades générées sont: cascade="delete" C'est typiquement le boulot d'hibernate de sauvegarder ces instances, et je ne devrais pas à avoir à forcer la sauvegarde manuellement. Mais est-ce généralisable à toutes les compositions ? Cordialement, Eric Chatellier -- Éric Chatellier - www.codelutin.com - 02.40.50.29.28

Par exemple, dans le code suivant : https://forge.codelutin.com/projects/faxtomail/repository/revisions/61/entr… Les lignes 119 à 139 et 142 à 144 sont inutiles.
