Abstract

A system, method and facility for manipulating registries on a computer system. The system includes a generic registry facility, which features functions classified according to the breadth of their applicability to varying types of registries. The registries may be classified as file-based and proprietary. The file-based registries may be binary or text-based. The generic registry facility provides a library of generic registry facility functions that may be included in a specific registry manipulation module through which a computer program can manipulate a specific registry. The generic registry facility functions may be customized by the developer of the registry manipulation module for a specific registry. The functions may include an action verification function that includes a commit sequence for ensuring that requested changes to a registry are made successfully. The functions may also include a trigger function for triggering events upon the occurrence of a change to a registry.

Claims

1. A registry manipulation system for use by a computer program in manipulating a specific registry on a computer system, the specific registry having a type of storage, the registry manipulation system comprising:

a registry manipulation facility for manipulating registries including a plurality of generic functions, the generic functions being defined within classes, the classes including a first level class and a second level class, wherein the second level class inherits the generic functions of the first level class; and

a registry manipulation module including a registry-specific definition for the specific registry and wherein the registry manipulation module inherits the generic functions of the second level class,

wherein the first level class provides an interface usable by the computer program, and wherein the second level class provides support for the type of storage for the registry.

2. The registry manipulation system of claim 1, wherein the second level class applies to file-based registries, the file-based registries being of a category, and wherein the registry manipulation facility further includes a third level class inheriting the functions of the second level class, wherein the third level class provides support for the category of the specific registry.

3. The registry manipulation system of claim 2, wherein the category is a category selected from the group including binary and text-based.

4. The registry manipulation system of claim 1, wherein the type of storage is a proprietary storage mechanism.

5. The registry manipulation system of claim 1, wherein the type of storage is file-based.

6. The registry manipulation system of claim 5, wherein the specific registry is a file-based registry and the file-based registry has a category, and wherein the registry manipulation facility further includes a third level class inheriting the functions of the second level class, wherein the third level class provides support for the category of the specific registry.

7. The registry manipulation system of claim 6, wherein the category is a category selected from the group including binary and text-based.

8. The registry manipulation system of claim 1, wherein the registry-specific definition includes a record structure definition for records of the specific registry.

9. The registry manipulation system of claim 1, wherein the generic functions includes functions for adding, deleting, getting and changing a record in the specific registry.

10. The registry manipulation system claimed in claim 1, wherein the generic functions include:

a manipulation function for performing a requested change to the specific registry, the manipulation function for creating a temporary registry, the temporary registry being a copy of the specific registry, and for causing the requested change to be made to the temporary registry; and

a verify action function for verifying that the requested change was successful, the verify action function for comparing the temporary registry to the specific registry to identify a difference between them, for comparing the difference to the requested change to determine if the difference and the requested change match, and for replacing the specific registry with the temporary registry when the difference and the requested change match.

11. The registry manipulation system claimed in claim 10, wherein the verify action function includes a return code, the return code being indicative of whether the difference and the requested change match to indicate success or failure.

12. The registry manipulation system claimed in claim 10, wherein the specific registry has a registry path name and the computer system further includes a backup registry having a backup path name, and wherein the verify action function unlinks the backup path name from the backup registry, links the backup path name to the specific registry and renames the temporary registry with the registry path name.

13. The registry manipulation system claimed in claim 10, wherein the verify action function successively compares each line in the specific registry to each line in the temporary registry to confirm that the lines match and identifies the difference when the lines do not match.

14. The registry manipulation system claimed in claim 10, wherein the requested change includes an addition to the specific registry.

15. The registry manipulation system claimed in claim 10, wherein the requested change includes a deletion from the specific registry.

16. The registry manipulation system claimed in claim 1, wherein the generic functions include:

a manipulation function for performing a requested change to the specific registry; and

a trigger function for performing an action in response to the performance of the requested change to the specific registry.

17. The registry manipulation system claimed in claim 16, wherein the action includes sending a signal to an active process.

18. A computer program product comprising a computer readable medium carrying program instructions for use by a computer program in manipulating a specific registry on a computer system, the registry having a type of storage, the program instructions including,

providing a registry manipulation facility for manipulating registries including a plurality of generic functions for manipulating registries, the generic functions being defined within classes, the classes including a first level class and a second level class, wherein the second level class inherits the generic functions of the first level class;

and

providing a registry manipulation module including a registry-specific definition for the specific registry and wherein the registry manipulation module inherits the generic functions of the second level class,

wherein the first level class provides an interface usable by the computer program, and wherein the second level class provides support for the type of storage for the registry.

19. The computer program product of claim 18, wherein the second level class applies to file-based registries, the file-based registries being of a category, and wherein the registry manipulation facility further includes a third level class inheriting the functions of the second level class, wherein the third level class provides support for the category of the specific registry.

20. The computer program product of claim 19, wherein the category is a category selected from the group including binary and text-based.

21. The computer program product of claim 18, wherein the type of storage is a proprietary storage mechanism.

22. The computer program product of claim 18, wherein the type of storage is file-based.

23. The computer program product of claim 22, wherein the specific registry is a file-based registry and the file-based registry has a category, and wherein the registry manipulation facility further includes a third level class inheriting the functions of the second level class, wherein the third level class provides support for the category of the specific registry.

24. The computer program product of claim 23, wherein the category is a category selected from the group including binary and text-based.
