Abstract

A version compatibility method may identify an interface provided by a first version of an operating system and identify an interface provided by a second version of the operating system. A monitoring module generates difference information between the first version and the second version of the operating system. A compatibility module on a host machine determines, using the difference information, whether a computer application program running on the host machine can resolve an interface dependency if an operating system running on the host machine is changed from the first version to the second version.

First claim

What is claimed is:

1. A method comprising:
receiving, at a host machine, an installable package, the installable package comprising difference information describing differences between a plurality of versions of an operating system, the difference information comprising a plurality of elements, each element corresponding to differences between corresponding versions of the plurality of versions of the operating system from an original version to a most recent version;
invoking the installable package; and
determining, by a processing device using the difference information and in response to an operating system running on the host machine being changed from a first version to a second version, whether a computer application program running on the host machine can resolve an interface dependency, wherein the determining comprises:
identifying a library provided by the first version of the operating system, the library utilized by the computer application program;
identifying an element, of the plurality of elements, the element corresponding to differences between the first version and the second version of the operating system; and
determining whether the element indicates that an interface for the library has been removed from the second version of the operating system.

2. The method of claim 1 , wherein the difference information comprises changes to the interfaces provided by the first version and the second version of the operating system.

3. The method of claim 1 , further comprising:
invoking the installable package on the host machine in response to a request to change the operating system running on the host machine from the first version to the second version.

4. The method of claim 1 , further comprising:
invoking the installable package on the host machine in response to a request to determine whether the computer application program is compatible with the second version of the operating system.

5. The method of claim 1 , wherein the computer application program is an independent software vendor (ISV) application.

6. The method of claim 1 , wherein the installable package is received through an online repository.

7. A system comprising:
a memory; and
a processing device operatively coupled to the memory, the processing device to:
receive, at a host machine, an installable package, the installable package comprising difference information describing differences between a plurality of versions of an operating system, the difference information comprising a plurality of elements, each element corresponding to differences between corresponding versions of the plurality of versions of the operating system from an original version to a most recent version;
invoke the installable package; and
determine, using the difference information and in response to an operating system running on the host machine being changed from a first version to a second version, whether a computer application program running on the host machine can resolve an interface dependency, wherein to determine, the processing device to:
identify a library provided by the first version of the operating system, the library utilized by the computer application program;
identifying an element, of the plurality of elements, the element corresponding to differences between the first version and the second version of the operating system; and
determine whether the element indicates that an interface for the library has been removed from the second version of the operating system.

8. The system of claim 7 , wherein the difference information comprises changes to the interfaces provided by the first version and the second version of the operating system.

9. The system of claim 7 , wherein the processing device is further to:
invoke the installable package on the host machine in response to a request to change the operating system running on the host machine from the first version to the second version.

10. The system of claim 7 , wherein the processing device is further to:
invoke the installable package on the host machine in response to a request to determine whether the computer application program is compatible with the second version of the operating system.

11. The system of claim 7 , wherein the computer application program is an independent software vendor (ISV) application.

12. The system of claim 7 , wherein the installable package is received through bootable media.

13. A non-transitory machine-readable storage medium storing instructions which when executed cause a processing device to:
receive, at a host machine, an installable package, the installable package comprising difference information describing differences between a plurality of versions of an operating system, the difference information comprising a plurality of elements, each element corresponding to differences between corresponding versions of the plurality of versions of the operating system from an original version to a most recent version;
invoke the installable package; and
determine, by the processing device using the difference information and in response to an operating system running on the host machine being changed from a first version to a second version, whether a computer application program running on the host machine can resolve an interface dependency, wherein to determine, the processing device to:
identify a library provided by the first version of the operating system, the library utilized by the computer application program;
identify an element, of the plurality of elements, the element corresponding to differences between the first version and the second version of the operating system; and
determine whether the element indicates that an interface for the library has been removed from the second version of the operating system.

14. The storage medium of claim 13 , wherein the difference information comprises changes to the interfaces provided by the first version and the second version of the operating system.

15. The storage medium of claim 13 , the instructions further to cause the processing device to:
invoke the installable package on the host machine in response to a request to change the operating system running on the host machine from the first version to the second version.

16. The storage medium of claim 13 , the instructions further to cause the processing device to:
invoke the installable package on the host machine in response to a request to determine whether the computer application program is compatible with the second version of the operating system.

17. The storage medium of claim 13 , wherein the computer application program is an independent software vendor (ISV) application.
