Problems solved by technology

[0007] Since the new version of the installation package will be compressed before generating the difference file, but the compression algorithm will destroy the data structure in the new version of the installation package, so that the compressed new version of the installation package and any compressed historical version of the installation package will be generated In addition to the content of the difference in the data itself, the difference file also contains the content of the structure difference, which increases the size of the difference file and increases the time and traffic spent by the client to download the difference file

Embodiment 1

[0062] This embodiment provides a method for incremental update, see figure 1 , the method flow provided by this embodiment is specifically as follows:

[0063] 101: Unpack the new version installation package to obtain the new version unpack folder, the new version unpack folder includes at least one new version unpack file and the new version signature subfolder, the new version signature subfolder includes at least one new version unpacked file;

[0064] 102: Obtain the header file information of each new version unpacked file under the new version unpacked folder, and perform format conversion on the header file information of each new version unpacked file to obtain a new version converted folder;

[0065] 103: Pack the new version conversion folder into a new version archive file package, and obtain at least one historical version archive file package;

[0066] 104: Generate a corresponding difference file according to the new version archive file package and each hist...

Embodiment 2

[0078] Embodiment two

[0079] This embodiment provides a method for incremental update. For ease of description, this embodiment takes the new version installation package as the V2.1 installation package, and the historical version installation package as the V2.0 installation package and V1.0 installation package as an example. , the method provided in this embodiment is illustrated in detail. see image 3 , the method flow provided by this embodiment is specifically as follows:

[0080] 301: The server unpacks the new version installation package to obtain the new version unpack folder. The new version unpack folder includes at least one new version unpack file and the new version signature subfolder. The new version signature subfolder Include at least one new version unpack file;

[0081] For this step, including but not limited to unpacking the new version installation package through an unpacking algorithm, this embodiment does not limit the specific unpacking algor...

Abstract

The invention discloses an increment updating method, equipment and system and belongs to the technical field of information processing. The increment updating method comprises the steps of performing format conversion on head file information of every new version unpacking file of an unpacked new version installation pack, packing into a new version archive file pack and acquiring at least one history version archive file pack; generating into corresponding difference files according to the new version archive file pack and every history version archive file pack to obtain at least one difference file and issuing. According to the increment updating method, the new version archive file pack is obtained only by conversion of head file formats of files in the new version installation pack and the difference files are generated according to the new version archive file pack and the history version archive file packs, so that the difference files are generated under the condition that a data structure is not damaged, data structural difference contents in the difference files are omitted, the sizes of the difference files are reduced, and accordingly time and flow for a client to load the difference files are reduced.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a method, device and system for incremental updating. 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. At the same time, 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 the difference files different from the installed version of the client from the server, which reduces the time and traffic spent by the client for downloading. ...
