S102, at differentiation file described in client, according to described client current version installation kit and described differentiation file, generates the redaction installation kit of described application program.
Described application program updating system comprises client and service end.
Wherein, described service end and described client can be service-specific end and the clients of described application program, can be also third party's service end and the clients being independent of outside described application program.If third party's service end and client, described third party's service end can be downloaded from network, or obtains by other means the installation kit of each version of described application program, and preserves the installation kit of described each version in described third party's service end.
Described differentiation file refers to the differential file of difference between the installation kit of two versions of describing described application program, when developer is uploading after the redaction of application program, this redaction installation kit and client current version installation kit can be carried out to differentiation scanning in described service end, and generate a differentiation file, also can be described as increment installation kit.
The generation of described differentiation file can represent by following formula:
F1=F2-F3；
Wherein, F1 is described differentiation file, the redaction installation kit that F2 is described application program, and F3 is described client current version installation kit.
Described in described client, after differentiation file, according to described client current version installation kit and described differentiation file, generate described redaction installation kit.The generation of described redaction installation kit represents with following formula:
F2=F3+F1。
Client generates described redaction installation kit, and it is scalable described application program that described redaction installation kit is installed.Can be set to particularly described user side and generate directly operation after described redaction installation kit, or send prompting message, prompting user can upgrade, the described redaction installation kit upgrading of reruning in the time receiving customer upgrade instruction.
The present invention is by obtaining the redaction installation kit of service end application programs and the differentiation file that client current version installation kit generates, and client need be only scalable described application program according to described client current version installation kit and described differentiation file generated redaction installation kit.The data volume of described differentiation file is less, has reduced the data traffic of downloading in application program updating process, has reduced communications cost and the communication cost of escalation process.
In the present invention, in described service end, preserve redaction installation kit and the client current version installation kit of described application program; And client current version installation kit described in described client storage need to escalate into described redaction installation kit.And conventionally, a described service end need to coordinate with multiple described clients, complete the application program updating of client described in each and operate.And the client current version installation kit of preserving in client described in each may be not identical, the client current version installation kit that for example user side A preserves is first version, and the client current version installation kit that user side B preserves is the second version, the redaction installation kit that described service end is preserved is third edition basis, needs the installation kit of the first version that described user side A is preserved and the installation kit of the second version that user side B preserves to be all upgraded to described third edition installation kit originally.
Therefore, the client current version installation kit of preserving in described service end can have multiple different versions, and for example, in example above, the installation kit of both having preserved first version in server is also preserved the installation kit of the second version.Preferably, in the time that service end generates described differentiation file, in advance by described redaction installation kit respectively from multiple different client current version installation kit comparisons, generate respectively corresponding described differentiation file, differentiation file described in each is kept to service end with the version information of corresponding each client current version installation kit.
