Method, equipment and system of incremental update

A server for incremental software update, comprising:

• memory;
• one or more processors;
• an unpacking module stored in the memory and to be executed by the one or more processors for unpacking a new version installation package to get a new version unpacked folder having at least one new version unpacked file;
• a first acquisition module stored in the memory and to be executed by the one or more processors for obtaining header file information of the at least one new version unpacked file in the new version unpacked folder;
• a transforming module stored in the memory and to be executed by the one or more processors for converting a format of the header file information of the at least one new version unpacked file to a new version convert folder, wherein the header file information comprises a file length, a file name length, a calibration value, a file name and data content in a second preset format;
• a packing module stored in the memory and to be executed by the one or more processors for packing the new version convert folder to a new version archive package;
• a second acquisition module stored in the memory and to be executed by the one or more processors for obtaining at least one historical version archive package;
• a generating module stored in the memory and to be executed by the one or more processors for generating and obtaining at least one differential file according to the new version archive package and the at least one historical version archive package;
• and
• a release module stored in the memory and to be executed by the one or more processors for releasing the at least one differential file wherein the at least one differential file that is released is selected by a client to download and form a second new version installation package according to the at least one differential file that is downloaded.

A method for updating a software, comprising:

• acquiring, by a device having one or more processors, a historical version installation package that corresponds to the software installed on the device, and downloading a differential file corresponding to the historical version installation package from a server;
• unpacking, by the device, the historical version installation package, and getting a historical version unpacked folders wherein the historical version unpacked folder comprises at least one historical version unpacked file and a historical version signature subfolder comprising at least one historical version unpacked file;
• obtaining, by the device, header file information of the at least one historical version unpacked file, and converting a format of the header file information of the at least one historical version unpacked file to a historical version transformed folder;
• packing, by the device, the historical version transformed folder into a historical version archive file package, and getting a new version archive file package according to the historical version archive file package and the differential file;
• unpacking, by the device, the new version archive file package, and getting a new version transformed folder;
• obtaining, by the device, header file information of files in the new version transformed folder, and converting a format of the header file information of files to a plurality of new version unpacked files;
• and
• getting, by the device, the new version installation package based on the plurality of new version unpacked files.

• a first unpacking module stored in the memory and to be executed by the one or more processors for unpacking the historical version installation package, and getting a historical version unpacked folders wherein the historical version unpacked folder comprises at least one historical version unpacked file and a historical version signature subfolder comprising at least one historical version unpacked file;
• a second acquisition module stored in the memory and to be executed by the one or more processors for header file information of the at least one historical version unpacked file in the historical version unpacked folder;
• a first transforming module stored in the memory and to be executed by the one or more processors for converting a format of the header file information of the at least one historical version unpacked file to a historical version transformed folder;
• a packing module stored in the memory and to be executed by the one or more processors for packing the historical version transformed folder into a historical version archive file package;
• a third acquisition module stored in the memory and to be executed by the one or more processors for acquiring a new version archive file package according to the historical version archive file package and the differential file;
• a second unpacking module stored in the memory and to be executed by the one or more processors for unpacking the new version archive file package, and getting a new version transformed folder;
• a fourth acquisition module stored in the memory and to be executed by the one or more processors for acquiring header file information of files in the new version transformed folder;
• a second transforming module stored in the memory and to be executed by the one or more processors for converting a format of the header file information of files in the new version transformed folder to a plurality of new version unpacked files;
• a fifth acquisition module stored in the memory and to be executed by the one or more processors for acquiring the new version installation package based on the plurality of new version unpacked files.
