pb module Shelve avec TextBuffer object

bonjour
j'ai mis ce post dans le forum général python, mais je n'inspire pas grand monde. Je tente à nouveau ici

j'ai un problème pour utiliser le module shelve.
Mon objectif est d'utiliser sa fonction de persistance pour stocker le buffer d'un textview de pygtk. C'est normalement un objet comme un autre. Mais j'ai un message d'erreur. J'ai cherché sur internet les restrictions d'usage de shelve sans succès.

Si une bonne âme pouvait me mettre sur la voie du problème. Quelle erreur je commet?
Voici un code qui fonctionne

pourquoi can't pickle TextBuffer objects, c'est normalement un objet comme un autre????
Merci d'avance de votre aide

bonjour
j'ai résolu une partie de mon problème.
la cause-racine vient là.

Le protocole version 0 est le protocole ASCII original et il est retro-comptatible avec les versions précédentes de Python

Le protocole version 1 est l'ancien format binaire qui est également compatible avec les anciennes versions de Python

Le protocole version 2 a été introduit avec Python 2.3. Il fournit un pickling plus efficace pour les classes de nouveau style.

Code:

---

db = shelve.open(save_file,protocol=2)

---

voilà il faut utiliser le bon protocole.

Le piège étant que le code ci-dessous fonctionne.
Dans l'état je n'ai pas encore compris, puisque class ShelveDemo(object):
est une classe nouveau style:ccool:
et cela fonctionne avec protocol=0 qui est la valeur par defaut.:oops:

NOTA: je suis en python 2.6:aie: mais j'aime :zoubi:

Avis donc à ceux qui rament avec shelve ne pas oublier de choisir le bon protocole......mais je suis sur qui il y a encore autre chose....

Si une bonne âme peut se pencher sur le pb du chargement :lol:

Bonjour
Personne n'a la moindre idée du problème que j'ai posé:cry::lol::cry::lol:

Bonjour je fais remonter le topic à la une...::mouarf::mouarf:
Je suis toujours en galère sur ce point
j'ai un objet Textview qui n'est pas persistant avec l'usage de Shelve

j'ai gratté et trouvé que selon le type d'objet il faut utilisé le bon protocole.

j'utilise python 2.6.5 et le meilleurs protocole est 2 les autres plantent.:aie::aie:

Je pense que c'est une problématique générale de persistance d'objet avec un cas particulier sur une instance de TextView.
J'ai mis ce topic aussi sur le forum python général......:cry:

Le symptôme , je stocke bien l'objet dans un fichier mais lorsque je veux recharger l'objet je n'ai pas d'affichage.
Quelqu'un aurait-il une piste???:roll::roll:

Bonjour
Je totalise 154 visites sur ma question et je n'ai aucun embryon de réponse.
Vous êtes vraiment très dur avec moi.......:cry::aie::cry::aie:
