Problems solved by technology
[0005] In order to solve the problem in the prior art that the server needs to perform a differential calculation on each difference file, correspondingly, the client also needs to perform an inverse difference calculation on each difference file, and the process of restoring the installation package of the new version by the client requires a relatively Too much time affects the update efficiency. The embodiment of the present invention provides a method and device for generating a program installation package. The technical solution is as follows:

The invention relates to a program installation package generation method and device. The method comprises the following steps that: when a server generates an update data package, combining difference files, carrying out differential calculation on a first combination file obtained by combination to obtain a differential file, and generating an update data package which contains the differentialfile; and according to the differential file contained in a differential data package and an old-version installation package pre-stored in a terminal, carrying out inverse differential calculation bythe terminal to obtain the first combination file, and generating a new-version installation package according to the first combination file. When the terminal generates a new-version data package, the inverse differential calculation only needs to be carried out on the differential file for one time to obtain each difference file, each differential file does not need to be independently subjected to the inverse differential calculation, the inverse differential calculation frequencies of the terminal can be reduced, so that time for generating the new-version installation package on a terminal side can be shortened, and efficiency for the terminal side to update an application can be improved.
Description
technical field [0001] The invention relates to the technical field of network applications, in particular to a method and device for generating a program installation package. Background technique [0002] With the continuous development of computer and network application technology, and the continuous popularization of smart devices such as smartphones, more and more applications are constantly enriching people's network life. [0003] The provider of the application program usually updates and improves the application program on a regular basis, so as to provide users with a better experience. Incremental update is a commonly used algorithm for generating an installation package of a new version of the application program. Specifically, after receiving the installation package of a new version of a certain application, the server providing update services for the application program compares the installation package of the new version with the installation package of the...
