Data file incremental updating method, server, client and system

Abstract

The invention discloses a data file incremental updating method, a server, a client and a system, which are used for improving the incremental updating efficiency, reducing the complexity of version management, and simplifying an incremental updating process. The data file incremental updating method includes: acquiring a new version of a data file, and acquiring a plurality of file blocks corresponding to the new version of the data file according to the new version of the data file; calculating a new version block proof test value of each file block according to the plurality of file blocks; and writing the new version block proof test value of each file block, and a file name and a download address corresponding to the new version of the data file in a configuration file, and providing the configuration file for a client so as to allow the client to complete incremental updating according to the configuration file.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for incremental updating of data files, a server, a client and a system. Background technique [0002] When the client performs a software update, it needs to download the new version installation package of the software from the server through the Internet, and the client needs to pay the corresponding download time and traffic for the download of the new version installation package. However, most of the files in the installation package of the new version and the files in the installation package of the installed version of the client have not changed, so a large part of the download time and traffic paid by the client is for these same files. of. The incremental update method only needs to download a patch package different from the installed version of the client from the server, which reduces the time and traffic spent by the client for downloading. Therefore, t...

Problems solved by technology

[0011] In the process of realizing the present invention, the inventor found that the above-mentioned incremental update method has at least the following disadvantages: 1), slow execution speed, and high memory usage of mobile devices

2) When there are more versions of the installation package, more patch packages need to be generated. From the above examples, there will be a large number of patch packages regardless of linear upgrade or direct upgrade of any version, which increases the complexity of version management of the installation package. Reduced version management efficiency

3) Since the server will compress the installation packages of each version before generating the patch package, the client also needs to decompress the patch package first when downloading the patch package, which complicates the entire incremental update process
