Abstract

Disclosed is a method and an apparatus for incremental upgrade. When a server generates an incremental file, it acquires sub-files of different types in an old version compressed file and a new version compressed file, and performs different difference comparison steps on the sub-files of different types, to obtain difference data files for corresponding types: for sub-files that satisfy a preset decompression condition, a decompression comparison method is used to perform difference comparison, and for sub-files that do not satisfy the preset decompression condition, a direct comparison method is used to perform difference comparison; subsequently, a client acquires the difference data files from the server, and according to the type of a difference data file, carries out a merge operation on the difference data file and the old version compressed file to obtain the new version compressed file.

Claims23

Dependent claims

A method for incremental upgrade, comprising:

acquiring, by a server, at least one of a first type sub-file, a second type sub-file, and a third type sub-file, wherein:
the first type sub-file is a file existing in a new version compressed file, but not in an old version compressed file,
the second type sub-file is a file existing in both the new version compressed file and the old version compressed file, and both satisfy a preset decompression condition, including the second type sub-file in the new version compressed file and the second type sub-file in the old version compressed file, and
the third type sub-file is a file existing in both the new version compressed file and the old version compressed file, and not satisfying, in part or wholly, the preset decompression condition, including the third type sub-file in the new version compressed file and the third type sub-file in the old version compressed file;
based on the acquired file comprising the second type sub-file, decompressing, by the server, the second type sub-file in the new version compressed file and the second type sub-file in the corresponding old version compressed file, and performing, by the server, difference comparison to obtain a first difference data file;
based on the acquired file comprising the third type sub-file, performing, by the server, difference comparison between the third type sub-file in the new version compressed file and the third type sub-file in the corresponding old version compressed file without decompression to obtain a second difference data file;
and
according to the acquired at least one of the first type sub-file, the first difference data file,, and the second difference data file, generating, by the server, an incremental file for a client to perform incremental upgrade.
