Problème à la libération

Libération de ressources lors

du fork

de la création d'un processus (fork)

Pour exécuter certaines tâches ( Modules, Workers, ... ), le Broker doit créer de nouveaux processus sur le système.

Sur les environnements UNIX et notamment Linux, la procédure pour créer un nouveau processus consiste à dupliquer le processus courant. L'appel système associé se nomme fork, ainsi, cette action est souvent appelé appelée un fork.

Sous Linux, l'opération de fork est rapide, l'allocation effective de la mémoire du nouveau processus se faisant lorsque le nouveau processus veut y accéder.

Python disposant d'un garbage collector, un outil parcourant la mémoire pour identifier les zones inutilisés inutilisées et la restituer au système, la mémoire héritée du parent finit par être intégralement copiée dans le nouveau processus.

Pour éviter une consommation inutile de ressources, après le fork, on nettoie les données inutiles issues du processus père  (mémoire principalement)

Plus concrètement, le Broker va supprimer les données produites par les modules qu'il a instanciéinstanciés.

Les modules peuvent fournir une méthode pour gérer la libération de leur leurs ressources.

Si cette méthode provoque une erreur, on retrouvera un log de ce style Dans tous les cas, le log suivant permet de suivre le nettoyage des ressources :
