Abstract
Methods for reducing storage and performing static analysis on violations across code base revisions are disclosed. An example method begins with receiving a child snapshot representing a code base at a specific revision. A parent snapshot is identified. Then, canonical representations for violations representing coding defects in the parent and child snapshots are computed. An example method determines matching violations between the snapshots, unmatched parent violations, and unmatched child violations. For matching violations that have different canonical representations, a mapping between the parent snapshot violation and the child snapshot violation is stored using their respective canonical representations. For unmatched parent violations, each violation's canonical representation is stored with an indication that the violation has been eliminated from the child snapshot. For unmatched child violations, each violation's canonical representation is stored with an indication that the violation has been introduced in the child snapshot.
