Performing partial analysis of a source code base

A system comprising:

• one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• receiving, from a user, a request for partial analysis results to identify source code violations introduced by the user in changes made by the user to one or more source code files in a first snapshot of a project;
• generating an initial set of primary source code files comprising only one or more source code files changed by the user relative to source code files in the first snapshot of the project;
• obtaining data representing a dependency graph of source code files in the project, wherein the dependency graph has a directed link from a first node representing a first source code file to a second node representing a second source code file whenever the first source code file imports the second source code file or uses one or more definitions in the second source code file;
• generating an augmented set of primary source code file, including adding, to the initial set of primary source code files, one or more additional source code files represented by nodes in the dependency graph having a link to any node representing any f the files in the initial set of primary source code files;
• generating a set of secondary source code files including identifying source code files represented by nodes to which a link in the dependency graph exists from any node representing any of the files in the augmented set of primary source code file;
• performing a partial analysis of the project using one or more files included in the augmented set of primary source code files an the set of secondary source code files to identify unmatched violations occurring in the augmented set of primary source code files but not occurring in the first snapshot, the unmatched violations being violations introduced by the uder in changes made by the user to the one or more source code files in the initial set of primary source code files;
• and
• providing partial analysis results for the files included in the augmented set of primary source code files, wherein the partial analysis results identify locations of the violations introduced by the user in the one or more source code files.

A computer program product, encoded on one or more computer-readable hardware storage devices, comprising instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

• receiving, from a user, a request for partial analysis results to identify source code violations introduced by the user in changes made by the user to one or more source code files in a first snapshot of a project;
• generating an initial set of primary source code files comprising only one or more source code files changed by the user relative to source code files in the first snapshot of the project;
• obtaining data representing a dependency graph of course code files in the project, wherein the dependency graph has a directed link from a first node representing a first source code file to a second node representing a second source code file whenever the first source code file imports the second source code file or uses one or more definitions in the second source code file;
• generating an augmented set of primary source code file, including adding, to the initial set of primary source code files, one or more additional source code files represented by nodes in the dependency graph having a link to any node representing any of the files in the initial set of primary source code files;
• generating a set of secondary source code files including identifying source code files represented by nodes to which a link in the dependency graph exists from any node representing any of the files in the augmented set of primary source code file;
• performing a partial analysis of the project using one or more files included in the augmented set of primary source code files and the set of secondary source code files but not occurring in the first snapshot, the unmatched violations being violations introduced bu the user in changes made by the user to the one or more source code filed in the initial set of primary source code files;
• and
• providing partial analysis results for the files included in the augmented set of primary source code files, wherein the partial analysis results identify locations of the violations introduced by the user in the one or more source code files.
