Abstract

A method, system, and computer program product for efficiently providing software product updates in a client'"'"'s computer system. A Software Product Update (SPU) utility initiates the software update process by downloading a response file. The response file comprises scripted code and encoded data for an update of application system files. The SPU utility processes the response file with the aid of a script processing engine (SPE), which is saved, along with installation files, on the client'"'"'s computer system during an initial software product installation. The SPU utility sets the installation properties within the installation file set to values which allow the SPE to access and run the scripted code. The embedded binary data is decoded with the aid of the running scripted code. The SPU utility completes the update of application system files and the installation properties file, with the aid of the decoded embedded data.

Claims

1. In a data processing system which includes a software application, installation files for the software application, and a script processing engine (SPE) to facilitate software updates, a method comprising:

storing, in a client system, a set of installation files for a software application and a script processing engine (SPE) which includes one or more of;

a set of scripting constructs to accept encoded binary data, process encoded binary data and update system files and properties; and

a facility to process installation properties;

the client system initiating updating of the software application, wherein the updating comprises initiating a server computer system to perform an on-the-fly comparison of a first set of files of a current program build of the software application with a second set of files of a release build of the software application at a server computer system to determine a set of file differences;

downloading a response file generated at the server computer system to the client system, the response file including code for one or more updates of a set of application system files and data, the data including a set of configuration keywords and parameters to guide a customized installation, wherein the response file includes only one or more select downloads based on the set of file differences;

the client system processing the response file by the sets of installation files;

processing the installation properties by the sets of installation files; and

updating, via a pre-determined code injection point, a set of application system files and an installation properties file, with the aid of the processed and decoded embedded data.

2. The method of claim 1, wherein the downloading the response file further comprises:

the client system automatically translating the set of file differences into a set of script code and encoded data; and

adding the set of script code and encoded data to the response file, which also includes the set of configuration keywords and parameters to guide a customized installation.

3. The method of claim 1, wherein processing the response file further comprises:

retrieving the set of configuration keywords and parameters from the response file; and

setting the installation properties within the installation file set to values which allow the SPE to access a scripted logic and encoded data, according to the set of configuration keywords and parameters from the response file.

4. The method of claim 3, wherein processing the installation properties further comprises:

passing the scripted logic to the SPE in order for the SPE to run the scripted logic, using values of the installation properties; and

decoding the encoded binary data with the aid of the scripted logic.

5. A data processing system comprising:

a processor;

a memory system;

a network connection to one or more server computer systems;

a utility executing on the processor that;

stores, in a client system, a set of installation files for a software application and a script processing engine (SPE) which includes one or more of;

a set of scripting constructs to accept encoded binary data, process encoded binary data and update system files and properties; and

a facility to process installation properties;

initiates an updating of the software application, wherein the updating comprises initiating a server computer system to perform an on the fly comparison of a first set of files of a current program build of the software application with a second set of files of a release build of the software application at a server computer system to determine a set of file differences;

downloads a response file generated at the server computer system to the client system, the response file including code for one or more updates of a set of application system files and data, the data including a set of configuration keywords and parameters to guide a customized installation, wherein the response file includes only one or more select downloads based on the set of file differences;

processes the response file by the sets of installation files;

processes the installation properties by the sets of installation files; and

updates, via a pre-determined code injection point, a set of application system files and an installation properties file, with the aid of the processed and decoded embedded data.

6. The system of claim 5, wherein the downloading the response file further comprises:

automatically translates the set of file differences into a set of script code and encoded data; and

adds the set of script code and encoded data to the response file, which also includes the set of configuration keywords and parameters to guide a customized installation.

7. The system of claim 5, wherein processing the response file further comprises:

retrieves the set of configuration keywords and parameters from the response file; and

sets the installation properties within the installation file set to values which allow the SPE to access a scripted logic and encoded data, according to the set of configuration keywords and parameters from the response file.

8. The system of claim 7, wherein processing the installation properties further comprises:

passes the scripted logic to the SPE in order for the SPE to run the scripted logic, using values of the installation properties; and

decodes the encoded binary data with the aid of the scripted logic.

9. A computer program product comprising:

a machine readable storage device; and

program code on the machine readable storage device that when executed by a data processing system performs the functions of;

storing, in a client system, a set of installation files for a software application and a script processing engine (SPE) which includes one or more of;
