Abstract

A computer program product includes program code for managing changes to one or more files via a link is associated with the changes that result in an updated version of the one or more files. A changed section determiner determines which sections associated with the one or more files have changed. The changed section operator further determines metadata regarding the nature of the changes to the sections. Based on the metadata a metrics generator generates a first weight associated with each of the changed sections. A mapping record generator generates a mapping record for each of the changed sections. A first mapping record comprises data associated with the first weight. The first mapping record is associated with a particular version of the one or more files and is linked to mapping records associated with other changed sections using the link.

Claims

1. An apparatus for managing changes to one or more files, the apparatus comprising:

a central processing unit;

a changed section determiner that;

determines a plurality of sections associated with one or more files that have changed, wherein the one or more files further comprises at least one code file and at least one documentation file; and

determines metadata regarding the nature of one or more changes to the plurality of sections, wherein the one or more changes resulted in an updated version of the one or more files;

a metrics generator that uses the metadata to generate a first weight associated with each of the one or more sections that have changed, assigns a greater first weight to a particular section that has changed based on at least one of;

a larger size of a change, a greater complexity of a change, and a more recent change; and

a mapping record generator that generates a set of mapping records comprising a mapping record for each of the plurality of sections that have changed, wherein a first mapping record of the set of mapping records comprises data associated with the first weight, wherein the first mapping record is associated with a particular version of the one or more files, and wherein the first mapping record is linked to each other mapping record in the set of mapping records that is associated with one or more other changed sections via a link, wherein the link is associated with the one or more changes, and wherein the set of mapping records associated with the link comprises the same identifier.

2. The apparatus of claim 1,

wherein the metadata is associated with at least one of:

a size of a change, a complexity of a change, and a recency of a change.

3. The apparatus of claim 1, further comprising:

a resolver that, in response to receiving a proposed change, retrieves one or more proximate change mapping records associated with one or more previous changes that are proximate to the proposed change.

4. The apparatus of claim 3, wherein the metrics generator further:

assigns a second weight to each of the one or more proximate change mapping records.

5. The apparatus of claim 3, wherein the resolver further:

obtains one or more further mapping records associated with one or more further changes having a same link as the one or more proximate change mapping records.

6. The apparatus of claim 5, wherein the metrics generator further:

assigns a third weight to each of the one or more further mapping records.

7. The apparatus of claim 5, wherein the resolver further:

generates one or more region records, wherein a region record is an aggregation of changes where an overlap exists between each of the one or more previous changes and the one or more further changes, wherein the one or more previous changes and the one or more further changes do not require the same link.

8. The apparatus of claim 7, wherein the metrics generator further:

assigns a fourth weight to each of the one or more region records.

9. The apparatus of claim 7, wherein the resolver further:

sorts the one or more region records.

10. The apparatus of claim 1, the program code further comprising code that when run on the computer, enables the computer to:

in response to receiving a proposed change, retrieve one or more proximate change mapping records associated with one or more previous changes that are proximate to the proposed change.

11. The apparatus of claim 10, the program code further comprising code that when run on the computer, enables the computer to:

assign a second weight to each of the one or more proximate change mapping records.

12. The apparatus of claim 10, the program code further comprising code that when run on the computer, enables the computer to:

obtain one or more further mapping records associated with one or more further changes having a same link as the one or more proximate change mapping records.

13. The apparatus of claim 12, the program code further comprising code that when run on the computer, enables the computer to:

assign a third weight to each of the one or more further mapping records.

14. The apparatus of claim 12, the program code further comprising code that when run on the computer, enables the computer to:

generate one or more region records, wherein a region record is an aggregation of changes where an overlap exists between each of the one or more previous changes and the one or more further changes, wherein the one or more previous changes and the one or more further changes do not require the same link.

15. The apparatus of claim 14, the program code further comprising code that when run on the computer, enables the computer to:

assign a fourth weight to each of the one or more region records.

16. The apparatus of claim 14, the program code further comprising code that when run on the computer, enables the computer to:

sort the one or more region records.

17. The apparatus of claim 1, wherein the metrics generator assigns a greater first weight to a particular section that has changed based on a greater complexity of a change, wherein generating the first weight associated with each of the plurality of sections that have changed further comprises the metrics generator calculating a cyclomatic complexity of each of an updated version of the one or more files and a preceding version of the one or more files.

18. A computer program product comprising program code stored on a non-transitory computer storage medium that when run on a computer, enables the computer to:

determine a plurality of sections associated with one or more files that have changed, wherein the one or more files further comprises at least one code file and at least one documentation file; and

determine metadata regarding the nature of one or more changes to the plurality of sections, wherein the one or more changes resulted in an updated version of the one or more files;

generate, using on the meta data, a first weight associated with each of the plurality of sections that have changed;

assigns a greater first weight to a particular section that has changed based on at least one of;

a larger size of a change, a greater complexity of a change, and a more recent change; and

generate a set of mapping records comprising a mapping record for each of the plurality of sections that have changed, wherein a first mapping record of the set of mapping records comprises data associated with the first weight, wherein the first mapping record is associated with a particular version of the one or more files, and wherein the first mapping record is linked to each other mapping record in the set of mapping records that is associated with one or more other changed sections via a link, wherein the link is associated with the one or more changes, and wherein the set of mapping records associated with the link comprises the same identifier.

19. The computer program product of claim 18,

wherein the metadata is associated with at least one of:

a size of a change, a complexity of a change, and a recency of a change.

20. The computer program product of claim 18, the program code further comprising code that when run on the computer, enables the computer to:

assign a greater first weight to a particular section that has changed based on a greater complexity of a change, wherein generating the first weight associated with each of the plurality of sections that have changed further comprises calculating a cyclomatic complexity of each of an updated version of the one or more files and a preceding version of the one or more files.
