Abstract

A risk level of a software commit is assessed through the use of a classifier. The classifier may be generated based on attributes pertaining to previous commits and used to determine a risk level for deployment of a software commit into a production environment based on attributes extracted from the software commit

First claim

What is claimed is:

1 . A method, comprising:
extracting, by a feature extraction engine, a plurality of attributes pertaining to a software commit; and determining, by a risk assessment engine, a risk level for deployment of the software commit into a production environment based on the extracted attributes.

2 . The method of claim 1 wherein the attributes include an attribute that provides information about the software commit, an attribute that provides information about a label for the software commit, and an attribute indicative of the code complexity of the software commit for which the risk level is determined.

3 . The method of claim 1 wherein determining the risk level includes providing the attributes to a classification engine.

4 . The method of claim 1 further comprising generating a classifier based on previous software commits, providing the attributes to the classifier, and wherein determining the risk level comprising running the classifier.

5 . The method of claim 4 wherein the risk level includes a plurality of levels.

6 . A non-transitory computer-readable storage device containing software that, when executed by a processor, causes the processor to:
determine a plurality of attributes pertaining to a software commit; provide the attributes to a classifier; and use the classifier to classify a risk level for deployment of the software commit into a production environment.

7 . The non-transitory computer-readable storage device of claim 6 wherein, when executed, the software causes the processor to generate the classifier based on previous commits.

8 . The non-transitory computer-readable storage device of claim 7 wherein, when executed, the software causes the processor to generate the classifier based on leave-1-out cross validation.

9 . The non-transitory computer-readable storage device of claim 6 wherein the attributes include an attribute that provides information about the software commit and an attribute that provides information about a label for the software commit.

10 . The non-transitory computer-readable storage device of claim 6 wherein the attributes include an attribute indicative of code complexity of the software commit for which the risk level is determined.

11 . The non-transitory computer-readable storage device of claim 6 wherein the software commit includes an update to an existing software application.

12 . The non-transitory computer-readable storage device of claim 6 further comprising a data structure to include a plurality of entries, each entry to correspond to a separate software commit and to include attributes specific to that software commit, each entry also to include a label that specifies whether the corresponding software commit was good or bad.

13 . A system, comprising:
a data structure to include a plurality of software commits, each software commit to include a plurality of attributes and a label, the attributes including at least one attribute about the software commit and the label indicating a success level of the software commit; a classifier engine to generate a classifier based on the software commits from the data structure.

14 . The system of claim 13 wherein the features include a plurality of attributes including a source control feature based on the software commit and a previous labels feature indicative of a label of a previous commit.

15 . The system of claim 14 , wherein the attributes also include a measure of code complexity of the software commit for which the risk level is determined
