Methods, systems, and apparatus, including computer programs encoded on computer storage media, for computing weights for source code alerts. One of the methods includes generating a respective sample of alerts for each feature of a plurality of features. One or more feature values are computed for alerts having a same respective attribute value for each feature of a plurality of features. An importance distribution that maps each feature value to a respective measure of importance for an alert having the feature value is used to compute a respective feature score for the feature using one or more feature values computed the alert. A respective weight is computed for each alert by combining the plurality of feature scores computed for the alert.

Weighting static analysis alerts

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for discounting source code contributions occurring in reverted commits. One of the methods includes identifying, in a time-ordered sequence of commits, one or more matching sequences of additions and deletions of the files which have the same file path, comprising. A value for a contribution metric is computed for a responsible developer entity including discounting portions of the metric resulting from additions and deletions in any of the identified matching sequence of additions and deletions for the files having the same file path.

Commit reversion detection

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing user-specific source code alert information. One of the methods includes receiving a user identifier of a user that has previously accessed source code of a code base, and receiving source code access data that includes access metrics related to prior user access of the source code. Based on the source code access data and on source code that has previously been accessed by the user, relevant source code that has previously been accessed by other users is determined. Source code alerts are received for the code base, and a user-specific organization of alerts is provided for the user that identifies alerts for source code problems occurring in the source code, including at least one source code unit that has previously been accessed by another user.
