Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for aggregating source code metric values. One of the methods includes obtaining data representing a directed graph, wherein one or more nodes of the graph are associated with a respective set of one or more metric instances, wherein each set of metric instances for each node includes all metric instances occurring in sets of any node descendant from the node in the graph, wherein each metric instance identifies a location in a source code base, and wherein each metric instance has a respective metric value, a respective identifier, and a respective attribute type. An attribute value is computed for a first node in the graph from the respective metric value of each metric instance in a first set of metric instances associated with the first node.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating widened types for computing measures of rework normalized churn. One of the methods includes determining a plurality of commit chains for a software developer. Respective measures of rework churn occurring in each commit chain are calculated. An overall rework factor is computed for the developer using the respective measures of rework churn for each commit chain in the plurality of commit chains for the developer. A measure of rework normalized churn is computed for the developer including adjusting the initial measure of churn by the overall rework factor. Productivity of the developer is quantified relative to one or more other developers using the measure of rework normalized churn for the developer.
