Abstract

Described herein are methods for sharing resource dependencies between applications stored on a system. For example, in at least certain embodiments, a computer-implemented method for sharing resource dependencies includes installing or initiating installation of multiple application bundles having one or more applications and respective resources on the system. Next, an installer determines identifiers (e.g., hash signatures) for first and second resources and determines whether the resources are identical if an identifier for the first resource matches an identifier for the second resource. Then, a link is created from the second application bundle to the first resource of the first application bundle if the first resource is identical to the second resource. The second resource may be removed from the system if it has been installed. Alternatively, installation of the second resource is terminated if it has not been installed on the system.

4. The computer-implemented method of claim 3, wherein determining whether the first resource is identical to the second resource if the first identifier matches the second identifier is based on a comparison of additional signature files including property list files of the first resource and additional signature files including property list files of the second resource.

5. The computer-implemented method of claim 1, wherein determining whether the second identifier matches a first identifier of the first resource comprises comparing the second identifier to the first identifier, which is stored in cache memory.

6. A non-transitory computer readable medium containing executable computer program instructions which when executed by a computing system cause said system to perform a method, the method comprising:

installing a second application bundle including a second application and an embedded second resource on the data processing system, wherein the data processing system includes a first application bundle including a first application and an embedded first resource;

determining a second identifier for the second resource;

removing the second resource from the data processing system if the first resource is identical to the second resource.

7. The non-transitory computer readable medium of claim 6, further comprising:

creating a link from the second application bundle to the first resource if the first resource is identical to the second resource.

8. The non-transitory computer readable medium of claim 6, wherein determining whether the first resource is identical to the second resource if the first identifier matches the second identifier is based on a comparison of additional signature files including at least one of permission sets, pathnames, and filenames of the first resource and additional signature files including at least one of permission sets, pathnames, and filenames of the second resource.

9. The non-transitory computer readable medium of claim 8, wherein determining whether the first resource is identical to the second resource if the first identifier matches the second identifier is based on a comparison of additional signature files of the first resource and additional signature files of the second resource.

10. The non-transitory computer readable medium of claim 6, wherein determining whether the second identifier matches a first identifier of the first resource comprises comparing the second identifier to the first identifier, which is stored in cache memory.

11. A data processing system, comprising:

a non-transitory storage unit to store a first application bundle including a first application and an associated first resource;

a processing system coupled to the non-transitory storage unit;

a cache memory coupled to the processing system; and

one or more programs, wherein the one or more programs are configured to be executed by the processing system, the programs including;

instructions to install a second application bundle including a second application and an associated second resource on the storage unit;

instructions to determine a second identifier for the second resource;

instructions to determine whether the second identifier matches a first identifier of the first resource;

instructions to determine whether the second identifier including a signature file matches a first identifier including a signature file of the first resource;

instructions to determine whether the first resource is identical to the second resource if the first identifier matches the second identifier, wherein determining whether the first resource is identical to the second resource if the first identifier matches the second identifier is based on a comparison of additional signature files of the first resource and additional signature files of the second resource; and

instructions to remove the second resource from the storage unit if the first resource is identical to the second resource.

12. The system of claim 11, wherein the one or more programs are configured to be executed by the processing system, the programs further including:

instructions to create a link from the second application bundle to the first resource if the first resource is identical to the second resource.

13. The system of claim 11, wherein determining whether the first resource is identical to the second resource if the first identifier matches the second identifier is based on a comparison of additional signature files including at least one of permission sets, pathnames, and filenames of the first resource and additional signature files including at least one of permission sets, pathnames, and filenames of the second resource.

14. The system of claim 13, wherein determining whether the first resource is identical to the second resource if the first identifier matches the second identifier is based on a comparison of additional signature files of the first resource and additional signature files of the second resource.
