Uses OpenRewrite to parse Java source across versions (11/17/21), builds class and package dependency graphs with JGraphT, detects cycle-breaking candidates using two graph algorithms, and returns everything in `CodebaseGraphDTO`. Entry point: `JavaGraphBuilder.getCodebaseGraphDTO()`. + +**graph-algorithms** — Two cycle-decomposition algorithms used by `JavaGraphBuilder`: +- *Directed Feedback Vertex Set* (`org.hjug.feedback.vertex.kernelized`) — kernelized algorithm; identifies the minimum vertex set to remove to break all cycles. +- *Feedback Arc Set with PageRank* (`org.hjug.feedback.arc.pageRank`) — identifies edges to remove; uses PageRank on the line digraph. Based on Geladaris et al. +- See `DIAGRAM.md` files in each algorithm package for pseudocode diagrams. + +**effort-ranker** — Runs PMD rules (`category/java/design.xml` + custom `CBORule`) to detect God Classes (ATFD, WMC, TCC) and highly coupled classes (CBO). Also detects Brain Classes, Data Classes, Feature Envy, and several other disharmonies in `DisharmonyDetector`. + +**change-proneness-ranker** — Uses JGit to read Git commit history and assign change-frequency scores to classes. + +**cost-benefit-calculator** — Orchestrates the full pipeline: runs effort-ranker and change-proneness-ranker, combines scores into `RankedDisharmony` objects. Main orchestration class: `CostBenefitCalculator`. + +**report** — Generates HTML (with embedded bubble charts), CSV, and JSON output. Reports with >4000 classes switch to a simplified 3D viewer. + +**cli** — PicoCLI-based executable. Entry: `org.hjug.refactorfirst.Main` → `ReportCommand`. + +**refactor-first-maven-plugin** — Maven plugin wrapper; key config options: `showDetails`, `backEdgeAnalysisCount` (default 50; set 0 for all), `analyzeCycles`, `excludeTests`. + +## Key Data Model + +`CodebaseGraphDTO` is the central transfer object passed between modules. It holds: +- JGraphT directed graphs for class and package dependencies +- Detected disharmony lists (God Classes, Brain Classes, etc.) +- Metrics per class (ATFD, WMC, TCC, CBO) + +`RankedDisharmony` carries the final prioritized output consumed by report generators. + +## Architectural Patterns + +- **Visitor** — `JavaVisitor` (OpenRewrite) walks the AST to collect class dependencies. +- **Pipeline** — `CostBenefitCalculator` chains multiple independent rankers then merges results. +- **DTO** — `CodebaseGraphDTO` decouples parsing from ranking and reporting. +- Lombok `@Data`/`@Builder` is used extensively; avoid adding boilerplate that Lombok already removes. + +## Testing + +JUnit 5 (Jupiter) with parameterized tests. Test fixtures live in `test-resources/src/test/resources`. When adding or modifying graph-algorithm behavior, check `JavaGraphBuilderTest` and `CircularReferenceCheckerTests` for integration-level coverage. + +Mutation testing via PIT (`pitest-maven`) is configured but not part of the default build; run explicitly if needed. + +## Java & Toolchain + +- Source/target: Java 11 minimum; OpenRewrite parser supports 11, 17, 21. +- Logging: SLF4J; use `log.debug()` for verbose per-class output, `log.info()` sparingly. +- Spotless enforces Palantir Java format — run `mvn spotless:apply` before committing. diff --git a/change-proneness-ranker/src/main/java/org/hjug/git/ChangePronenessRanker.java b/change-proneness-ranker/src/main/java/org/hjug/git/ChangePronenessRanker.java index 2b57a2cd..ec4ac789 100644 --- a/change-proneness-ranker/src/main/java/org/hjug/git/ChangePronenessRanker.java +++ b/change-proneness-ranker/src/main/java/org/hjug/git/ChangePronenessRanker.java @@ -9,24 +9,33 @@ public class ChangePronenessRanker { private final TreeMap changeCountsByTimeStamps = new TreeMap<>();

+ * Unlike {@link File}, which always implies a file path on the current computer, + * {@link FilePath} represents a file path on a specific agent or the controller. + * + * Despite that, {@link FilePath} can be used much like {@link File}. It exposes + * a bunch of operations (and we should add more operations as long as they are + * generally useful), and when invoked against a file on a remote node, {@link FilePath} + * executes the necessary code remotely, thereby providing semi-transparent file + * operations. + * + *

Using {@link FilePath} smartly

+ *

+ * The transparency makes it easy to write plugins without worrying too much about + * remoting, by making it works like NFS, where remoting happens at the file-system + * layer. + * + *

+ * But one should note that such use of remoting may not be optional. Sometimes, + * it makes more sense to move some computation closer to the data, as opposed to + * move the data to the computation. For example, if you are just computing a MD5 + * digest of a file, then it would make sense to do the digest on the host where + * the file is located, as opposed to send the whole data to the controller and do MD5 + * digesting there. + * + *

+ * {@link FilePath} supports this "code migration" by in the + * {@link #act(FileCallable)} method. One can pass in a custom implementation + * of {@link FileCallable}, to be executed on the node where the data is located. + * The following code shows the example: + * + * 

+ * void someMethod(FilePath file) {
+ *     // make 'file' a fresh empty directory.
+ *     file.act(new Freshen());
+ * }
+ * // if 'file' is on a different node, this FileCallable will
+ * // be transferred to that node and executed there.
+ * private static final class Freshen implements FileCallable<Void> {
+ *     private static final long serialVersionUID = 1;
+ *     @Override public Void invoke(File f, VirtualChannel channel) {
+ *         // f and file represent the same thing
+ *         f.deleteContents();
+ *         f.mkdirs();
+ *         return null;
+ *     }
+ * }
+ *
+ * + *

+ * When {@link FileCallable} is transferred to a remote node, it will be done so + * by using the same Java serialization scheme that the remoting module uses. + * See {@link Channel} for more about this. + * + *

+ * {@link FilePath} itself can be sent over to a remote node as a part of {@link Callable} + * serialization. For example, sending a {@link FilePath} of a remote node to that + * node causes {@link FilePath} to become "local". Similarly, sending a + * {@link FilePath} that represents the local computer causes it to become "remote." + * + * @author Kohsuke Kawaguchi + * @see VirtualFile + */ +public final class FilePath implements SerializableOnlyOverRemoting { + /** + * Maximum http redirects we will follow.
