Abstract

A first code version is received. The first code version includes a plurality of code features, such as methods or classes. A second code version is received. The second code version includes a plurality of code features. The first code version is executed. A first plurality of code features executed during the execution of the first code version are determined. A second plurality of code features differing between the first and second code versions are determined. The first and second plurality of code features are compared. An indication is provided that a code feature is potentially relevant to the code behavior if the code feature is present in the first plurality of code features and in the second plurality of code features.

Claims

1. One or more non-transitory computer-readable storage media storing computer-executable instructions for causing a computing system to perform processing to identify at least one code feature potentially associated with a code behavior of interest, the processing comprising:

receiving a first code version, the first code version comprising a plurality of code features;

receiving a second code version, the second code version comprising a plurality of code features;

executing the first code version;

determining a first plurality of code features executed during the execution of the first code version;

determining a second plurality of code features differing between the first code version and the second code version;

comparing the first plurality of code features and the second plurality of code features; and

providing an indication that a code feature is potentially associated with the code behavior of interest if the code feature is present in the first plurality of code features and the second plurality of code features.

2. The one or more non-transitory computer-readable storage media of claim 1, wherein determining a first plurality of code features executed during the execution of the first code version comprises analyzing a call stack associated with the execution of the first code version.

3. The one or more non-transitory computer-readable storage media of claim 1, the processing further comprising, for at least one code feature indicated as potentially associated with the code behavior of interest:

comparing source code of the first code version associated with the at least one code feature with source code of the second code version associated with the at least one code feature;

displaying the first source code version with an indication of changes to the second source code version.

4. The one or more non-transitory computer-readable storage media of claim 3, wherein a plurality of code features are indicated as potentially associated with the code behavior of interest, and the processing further comprises:

ranking the plurality of code features.

5. The one or more non-transitory computer-readable storage media of claim 1, wherein a plurality of code features are indicated as potentially associated with the code behavior of interest, and the processing further comprises:

ranking the plurality of code features;

wherein the ranking is based at least in part on the identity of individuals associated with changes to the code features.

6. The one or more non-transitory computer-readable storage media of claim 1, wherein a plurality of code features are indicated as potentially associated with the code behavior of interest, and the processing further comprises:

ranking the plurality of code features;

wherein the code features are methods of one or more classes and the ranking is based at least in part on the identity of the classes.

7. The one or more non-transitory computer-readable storage media of claim 1, the processing further comprising:

ranking the plurality of code features;

wherein the code features are methods of one or more classes and the ranking is based at least in part on a number of changed methods associated with the one or more classes.

8. The one or more non-transitory computer-readable storage media of claim 1, wherein the determining of the first or second plurality of code features comprises applying at least one filter criterion.

9. The one or more non-transitory computer-readable storage media of claim 1, wherein the determining of the first or second plurality of code features comprises applying at least one filter criterion, the at least one filter criterion comprising a user identifier.

10. The one or more non-transitory computer-readable storage media of claim 1, wherein the determining of the first or second plurality of code features comprises applying at least one filter criterion, the at least one filter criterion comprising at least one class identifier.

11. The one or more non-transitory computer-readable storage media of claim 1, wherein determining the first plurality of code features comprises applying at least one filter criterion, the at least one filter criterion comprising at least one execution identifier.

12. The one or more non-transitory computer-readable storage media of claim 1, wherein determining the second plurality of code features comprises:

determining definition information for each of the code features; and

comparing the definition information between the first and second code versions.

13. The one or more non-transitory computer-readable storage media of claim 1, wherein determining the second plurality of code features comprises:

determining implementation information for each of the code features; and

comparing the implementation information between the first and second code versions.

14. The one or more non-transitory computer-readable storage media of claim 1, wherein determining the second plurality of code features comprises:

determining definition information for each of the code features;

comparing the definition information between the first and second code versions;

determining implementation information for at least code features having the same definition information in the first and second code versions; and

if the definition information for a code feature is the same in the first and second code versions, comparing the implementation information of the code feature in the first and second code versions.

15. The one or more non-transitory computer-readable storage media of claim 1, wherein determining the second plurality of code features comprises:

determining definition information for each of the code features;

comparing the definition information between the first and second code versions;

determining implementation information for at least code features having the same definition information in the first and second code versions; and

if the definition information for a code feature is the same in the first and second code versions, comparing the implementation information of the code feature in the first and second code versions;

wherein, if the definition information for a code feature differs between the first and second code versions, the code feature is an added or deleted code feature, if the definition information for a code feature is the same between the first and second code versions, but the implementation information differs, the code feature is a changed code feature, and, if the definition and implementation for the code feature is the same between the first and second code versions, the code feature is unchanged.

16. The one or more non-transitory computer-readable storage media of claim 1, wherein executing the first code version comprises:

executing a plurality of stored commands.

17. The one or more non-transitory computer-readable storage media of claim 1, wherein determining a second plurality of code features comprises determining added code features, deleted code features, and modified code features.

18. The one or more non-transitory computer-readable storage media of claim 1, wherein the code behavior of interest comprises a runtime error.

19. A computing system that implements a code analysis system, the computing system comprising:

memory;

one or more processing units coupled to the memory; and

one or more non-transitory computer readable storage media storing instructions that, when loaded into the memory, cause the one or more processing units to perform operations for;
