Abstract
(EN)
Disclosed are a method, apparatus and device for generating a differential upgrade package. The method comprises: respectively dividing a source version file and a target version file into multiple blocks according to the length of a candidate block (201); comparing the blocks of the source version file with the blocks of the target version file to obtain difference information and duplication dependency relationships between the blocks of the source version file and the blocks of the target version file (202); and generating a differential upgrade package according to the difference information and the duplication dependency relationships (203).

La présente invention concerne un procédé, un appareil et un dispositif permettant de générer un paquet de mise à niveau différentiel. Le procédé comprend les étapes suivantes : diviser respectivement un fichier de version source et un fichier de version cible en de multiples blocs en fonction de la longueur d'un bloc candidat (201) ; comparer les blocs du fichier de version source avec les blocs du fichier de version cible pour obtenir des informations de différence et des relations de dépendance de duplication entre les blocs du fichier de version source et les blocs du fichier de version cible (202) ; et générer un paquet de mise à niveau différentiel conformément aux informations de différence et aux relations de dépendance de duplication (203).
