Differential upgrade patch manufacturing method and device

Abstract

The invention discloses a differential upgrade patch manufacturing method and device. The method comprises the steps that binary data of a source version are obtained, and mathematical transformation and sorting are carried out on the data to obtain a metadata set, wherein the metadata set comprises set attribute data with the minimum base unit; the data in the metadata set are serialized into an intermediate file; when a differential upgrade patch needs to be manufactured, differentiation analysis is carried out on the source version and a target version according to the intermediate file so as to build a differential upgrade patch. According to the differential upgrade patch manufacturing method and device, the intermediate file is utilized for manufacturing the differential upgrade patch, the differential upgrade patch manufacturing efficiency is improved, and differential upgrade patch manufacturing time is shortened; in addition, due to the fact that a cache optimization mechanism is introduced, the time spent for the processing process in which a differential patch tool is used for manufacturing a differential patch with the longest time is shortened, working efficiency is further improved, the labor cost is saved, and the differential upgrade technology is further applied and popularized.

Description

technical field [0001] The present invention relates to the field of differential upgrade technology, in particular to a method for making a differential upgrade package and a device thereof. Background technique [0002] Usually, the terminal device needs to upgrade the corresponding firmware after a period of time, but due to the limitation of the storage space of the device, it cannot accommodate a complete new version of data for upgrading, so it needs to be based on the difference between the two new and old versions of firmware, Make a differential upgrade package, and upgrade the firmware of the old version according to the differential upgrade package, so as to reduce the overhead of storage space. [0003] The time overhead required to make a differential package through the existing technology mainly depends on the size and specific difference degree of the two new and old versions of firmware, and the production efficiency of the differential package is low. In a...

[0003] The time overhead required to make a differential package through the existing technology mainly depends on the size and specific difference of the two new and old versions of firmware, and the production efficiency of the production package is low

In addition, some differential techniques are currently proposed in some public documents. This type of differential technique will calculate an intermediate temporary conversion file by its own algorithm, but there is no such intermediate file in the prior art. Technology for upgrading packages to improve production efficiency of differential packages
