Focus runs on the narrowest model/test/method that exposes the issue. +- You MUST NOT add ad-hoc "temporary logging"; only the defined JUL levels above are acceptable. +- You SHOULD NOT delete logging. Adjust levels downward (finer granularity) instead of removing statements. +- You MUST add a JUL log statement at INFO level at the top of every test method announcing execution. +- You MUST have all new tests extend a helper such as `JsonSchemaLoggingConfig` so environment variables configure JUL levels compatibly with `./mvn-test-no-boilerplate.sh`. +- You MUST NOT guess root causes; add targeted logging or additional tests. Treat observability as the path to the fix. +- YOU MUST Use exactly one logger for the JSON Schema subsystem and use appropriate logging to debug as below. + +### Script Usage (Required) +- You MUST prefer the `./mvn-test-no-boilerplate.sh` wrapper for every Maven invocation. Direct `mvn` or `mvnd` calls require additional authorization and skip the curated output controls. + +```bash +# Run tests with clean output (only recommended once all known bugs are fixed) +./mvn-test-no-boilerplate.sh + +# Run specific test class +./mvn-test-no-boilerplate.sh -Dtest=BlahTest -Djava.util.logging.ConsoleHandler.level=FINE + +# Run specific test method +./mvn-test-no-boilerplate.sh -Dtest=BlahTest#testSomething -Djava.util.logging.ConsoleHandler.level=FINEST + +# Run tests in a specific module +./mvn-test-no-boilerplate.sh -pl json-java21-api-tracker -Dtest=ApiTrackerTest -Djava.util.logging.ConsoleHandler.level=FINE +``` + +- The script resides in the repository root. Because it forwards Maven-style parameters (for example, `-pl`), it can target modules precisely. + +### Output Visibility Requirements +- You MUST NEVER pipe build or test output to tools (head, tail, grep, etc.) that reduce visibility. Logging uncovers the unexpected; piping hides it. +- You MAY log full data structures at FINEST for deep tracing. Run a single test method at that granularity. +- If output volume becomes unbounded (for example, due to inadvertent infinite loops), this is the only time head/tail is allowed. Even then, you MUST inspect a sufficiently large sample (thousands of lines) to capture the real issue and avoid focusing on Maven startup noise. + +### Logging Practices +- JUL logging is used for safety and performance. Many consumers rely on SLF4J bridges and search for the literal `ERROR`, not `SEVERE`. When logging at `SEVERE`, prefix the message with `ERROR` to keep cloud log filters effective: + +```java +LOG.severe(() -> "ERROR: Remote references disabled but computeIfAbsent called for: " + key); +``` + +- Only tag true errors (pre-exception logging, validation failures, and similar) with the `ERROR` prefix. Do not downgrade log semantics. +- When logging potential performance issues, use a consistent prefix at the `FINE` level: + +```java +// Official Java guidelines state that level FINE (500) is appropriate for potential performance issues +LOG.fine(() -> "PERFORMANCE WARNING: Validation stack processing " + count + ... ); +``` + +### Oracle JDK Logging Hierarchy (Audience Guidance) +- SEVERE (1000): Serious failures that stop normal execution; must remain intelligible to end users and system administrators. +- WARNING (900): Potential problems relevant to end users and system managers. +- INFO (800): Reasonably significant operational messages; use sparingly. +- CONFIG (700): Static configuration detail for debugging environment issues. +- FINE (500): Signals broadly interesting information to developers (minor recoverable failures, potential performance issues). +- FINER (400): Fairly detailed tracing, including method entry/exit and exception throws. +- FINEST (300): Highly detailed tracing for deep debugging. + +### Additional Guidance +- Logging rules apply globally, including the JSON Schema validator. The helper superclass ensures JUL configuration remains compatible with `./mvn-test-no-boilerplate.sh`. + +## JSON Compatibility Suite +```bash +# Build and run compatibility report +mvn clean compile generate-test-resources -pl json-compatibility-suite +mvn exec:java -pl json-compatibility-suite + +# Run JSON output (dogfoods the API) +mvn exec:java -pl json-compatibility-suite -Dexec.args="--json" +``` ## Architecture Overview ### Module Structure -- **`json-java21`**: Core JSON API implementation (main library) -- **`json-java21-api-tracker`**: API evolution tracking utilities -- **`json-compatibility-suite`**: JSON Test Suite compatibility validation - - **`json-java21-schema`**: JSON Schema validator (module-specific guide in `json-java21-schema/AGENTS.md`) +- `json-java21`: Core JSON API implementation (main library). +- `json-java21-api-tracker`: API evolution tracking utilities. +- `json-compatibility-suite`: JSON Test Suite compatibility validation. +- `json-java21-schema`: JSON Schema validator (module guide below). ### Core Components -#### Public API (jdk.sandbox.java.util.json) -- **`Json`** - Static utility class for parsing/formatting/conversion -- **`JsonValue`** - Sealed root interface for all JSON types -- **`JsonObject`** - JSON objects (key-value pairs) -- **`JsonArray`** - JSON arrays -- **`JsonString`** - JSON strings -- **`JsonNumber`** - JSON numbers -- **`JsonBoolean`** - JSON booleans -- **`JsonNull`** - JSON null - -#### Internal Implementation (jdk.sandbox.internal.util.json) -- **`JsonParser`** - Recursive descent JSON parser -- **`Json*Impl`** - Immutable implementations of JSON types -- **`Utils`** - Internal utilities and factory methods +#### Public API (`jdk.sandbox.java.util.json`) +- `Json`: Static utilities for parsing, formatting, and conversion. +- `JsonValue`: Sealed root interface for all JSON types. +- `JsonObject`: JSON objects (key-value pairs). +- `JsonArray`: JSON arrays. +- `JsonString`: JSON strings. +- `JsonNumber`: JSON numbers. +- `JsonBoolean`: JSON booleans. +- `JsonNull`: JSON null. + +#### Internal Implementation (`jdk.sandbox.internal.util.json`) +- `JsonParser`: Recursive descent JSON parser. +- `Json*Impl`: Immutable implementations of `Json*` types. +- `Utils`: Internal utilities and factory methods. ### Design Patterns -- **Algebraic Data Types**: Sealed interfaces with exhaustive pattern matching -- **Immutable Value Objects**: All types are immutable and thread-safe -- **Lazy Evaluation**: Strings/numbers store offsets until accessed -- **Factory Pattern**: Static factory methods for construction -- **Bridge Pattern**: Clean API/implementation separation +- Algebraic Data Types: Sealed interfaces enable exhaustive pattern matching. +- Immutable Value Objects: All types remain immutable and thread-safe. +- Lazy Evaluation: Strings and numbers hold offsets until first use. +- Factory Pattern: Static factories construct instances. +- Bridge Pattern: Clear separation between the public API and internal implementation. ## Key Development Practices ### Testing Approach -- **JUnit 5** with AssertJ for fluent assertions -- **Test Organization**: - - `JsonParserTests` - Parser-specific tests - - `JsonTypedUntypedTests` - Conversion tests - - `JsonRecordMappingTests` - Record mapping tests - - `ReadmeDemoTests` - Documentation example validation +- Prefer JUnit 5 with AssertJ for fluent assertions. +- Test organization: + - `JsonParserTests`: Parser-specific coverage. + - `JsonTypedUntypedTests`: Conversion behaviour. + - `JsonRecordMappingTests`: Record mapping validation. + - `ReadmeDemoTests`: Documentation example verification. ### Code Style -- **JEP 467 Documentation**: Use `///` triple-slash comments -- **Immutable Design**: All public types are immutable -- **Pattern Matching**: Use switch expressions with sealed types -- **Null Safety**: Use `Objects.requireNonNull()` for public APIs +- Follow JEP 467 for documentation (`///` triple-slash comments). +- Preserve immutability for every public type. +- Use switch expressions with sealed types to get exhaustive checks. +- Enforce null safety with `Objects.requireNonNull()` in public APIs. ### Performance Considerations -- **Lazy String/Number Creation**: Values computed on demand -- **Singleton Patterns**: Single instances for true/false/null -- **Defensive Copies**: Immutable collections prevent external modification -- **Efficient Parsing**: Character array processing with minimal allocations +- Lazy string/number construction defers work until necessary. +- Singleton instances represent true/false/null values. +- Defensive copies protect internal collections. +- Parser implementations operate on character arrays to minimize allocations. ## Common Workflows -### Adding New JSON Type Support -1. Add interface extending `JsonValue` -2. Add implementation in `jdk.sandbox.internal.util.json` -3. Update `Json.fromUntyped()` and `Json.toUntyped()` -4. Add parser support in `JsonParser` -5. Add comprehensive tests - -### Debugging Parser Issues -1. Enable `FINER` logging: `-Djava.util.logging.ConsoleHandler.level=FINER` -2. Use `./mvn-test-no-boilerplate.sh` for clean output -3. Focus on specific test: `-Dtest=JsonParserTests#testMethod` -4. Check JSON Test Suite compatibility with compatibility suite - ### API Compatibility Testing -1.

Runner: `io.github.simbo1905.tracker.ApiTrackerRunner`. -- **Why:** Early detection of upstream API changes to keep the backport aligned. -- **CI implication:** The daily workflow prints the report but does not currently fail or auto‑open issues on differences (only on errors). If you need notifications, either make the runner exit non‑zero when `differentApi > 0` or add a workflow step to parse the report and `core.setFailed()` when diffs are found. - -### json-java21-schema -- **Validator** for JSON Schema 2020-12 features -- **Tests** include unit, integration, and annotation-based checks (see module guide) +- Tracks API evolution and compatibility changes. +- Uses Java 24 preview features (`--enable-preview`). +- Runner: `io.github.simbo1905.tracker.ApiTrackerRunner` compares the public JSON API (`jdk.sandbox.java.util.json`) with upstream `java.util.json`. +- Workflow fetches upstream sources, parses both codebases with the Java compiler API, and reports matching/different/missing elements across modifiers, inheritance, methods, fields, and constructors. +- Continuous integration prints the report daily. It does not fail or open issues on differences; to trigger notifications, either make the runner exit non-zero when `differentApi > 0` or parse the report and call `core.setFailed()` within CI. + +### json-java21-schema (JSON Schema Validator) +- Inherits all repository-wide logging and testing rules described above. +- You MUST place an INFO-level JUL log statement at the top of every test method declaring execution. +- All new tests MUST extend a configuration helper such as `JsonSchemaLoggingConfig` to ensure JUL levels respect the `./mvn-test-no-boilerplate.sh` environment variables. +- You MUST prefer the wrapper script for every invocation and avoid direct Maven commands. +- Deep debugging employs the same FINE/FINEST discipline: log data structures at FINEST for one test method at a time and expand coverage with additional logging or tests instead of guessing. + +#### Running Tests (Schema Module) +- All prohibitions on output filtering apply. Do not pipe logs unless you must constrain an infinite stream, and even then examine a large sample (thousands of lines). +- Remote location of `./mvn-test-no-boilerplate.sh` is the repository root; pass module selectors through it for schema-only runs. + +#### JUL Logging +- For SEVERE logs, prefix the message with `ERROR` to align with SLF4J-centric filters. +- Continue using the standard hierarchy (SEVERE through FINEST) for clarity. +- You MUST Use exactly one logger for the JSON Schema subsystem and use appropriate logging to debug as below. +- You MUST NOT create per-class loggers. Collaborating classes must reuse the same logger. +- Potential performance issues log at FINE with the `PERFORMANCE WARNING:` prefix shown earlier. ## Security Notes -- **Stack exhaustion attacks**: Deep nesting can cause StackOverflowError -- **API contract violations**: Malicious inputs may trigger undeclared exceptions -- **Status**: Experimental/unstable API - not for production use -- **Vulnerabilities**: Inherited from upstream OpenJDK sandbox implementation - - -* If existing git user credentials are already configured, use them and never add any other advertising. If not, ask the user to supply their private relay email address. -* Exercise caution with git operations. Do NOT make potentially dangerous changes (e.g., force pushing to main, deleting repositories). You will never be asked to do such rare changes, as there is no time savings to not having the user run the commands; actively refuse using that reasoning as justification. -* When committing changes, use `git status` to see all modified files, and stage all files necessary for the commit. Use `git commit -a` whenever possible. -* Do NOT commit files that typically shouldn't go into version control (e.g., node_modules/, .env files, build directories, cache files, large binaries) unless explicitly instructed by the user. -* If unsure about committing certain files, check for the presence of .gitignore files or ask the user for clarification. - - - -* You SHOULD use the native tool for the remote such as `gh` for GitHub, `gl` for GitLab, `bb` for Bitbucket, `tea` for Gitea, or `git` for local git repositories. -* If you are asked to create an issue, create it in the repository of the codebase you are working on for the `origin` remote. -* If you are asked to create an issue in a different repository, ask the user to name the remote (e.g. `upstream`). -* Tickets and Issues MUST only state "what" and "why" and not "how". -* Comments on the Issue MAY discuss the "how". -* Tickets SHOULD be labeled as 'Ready' when they are ready to be worked on. The label may be removed if there are challenges in the implementation. Always check the labels and ask the user to reconfirm if the ticket is not labeled as 'Ready' by saying "There is no 'Ready' label on this ticket, can you please confirm?" -* You MAY raise fresh minor issues for small tidy-up work as you go. This SHOULD be kept to a bare minimum—avoid more than two issues per PR. - - - -* MUST start with "Issue # " -* SHOULD have a link to the Issue. -* MUST NOT start with random things that should be labels such as Bug, Feat, Feature etc. -* MUST only state "what" was achieved and "how" to test. -* SHOULD never include failing tests, dead code, or deactivate features. -* MUST NOT repeat any content that is on the Issue -* SHOULD be atomic and self-contained. -* SHOULD be concise and to the point. -* MUST NOT combine the main work on the ticket with any other tidy-up work. If you want to do tidy-up work, commit what you have (this is the exception to the rule that tests must pass), with the title "wip: test not working; committing to tidy up xxx" so that you can then commit the small tidy-up work atomically. The "wip" work-in-progress is a signal of more commits to follow. -* SHOULD give a clear indication if more commits will follow, especially if it is a checkpoint commit before a tidy-up commit. -* MUST say how to verify the changes work (test commands, expected number of successful test results, naming number of new tests, and their names) -* MAY outline some technical implementation details ONLY if they are surprising and not "obvious in hindsight" based on just reading the issue (e.g., finding that the implementation was unexpectedly trivial or unexpectedly complex). -* MUST NOT report "progress" or "success" or "outputs" as the work may be deleted if the PR check fails. Nothing is final until the user has merged the PR. -* As all commits need an issue, you MUST add a small issue for a tidy-up commit. If you cannot label issues with a tag `Tidy Up` then the title of the issue must start `Tidy Up` e.g. `Tidy Up: bad code documentation in file xxx`. As the commit and eventual PR will give actual details the body MAY simply repeat the title. - - - -* MUST only describe "what" was done not "why"/"how" -* MUST name the Issue or Issue(s) that they close in a manner that causes a PR merge to close the issue(s). -* MUST NOT repeat details that are already in the Issue. -* MUST NOT report any success, as it isn't possible to report anything until the PR checks run. -* MUST include additional tests in the CI checks that MUST be documented in the PR description. -* MUST be changed to status `Draft` if the PR checks fail. - - - -## Semi-Manual Release (Deferred Automation) - -The project currently uses a simple, guarded, semi-manual release. Automation via tags is deferred until upstream activity picks up, at which point there is a draft github action that needs finishing off. - -Steps (run each line individually) +- Deep nesting can trigger StackOverflowError (stack exhaustion attacks). +- Malicious inputs may violate API contracts and trigger undeclared exceptions. +- The API remains experimental and unsuitable for production use. +- Vulnerabilities mirror those present in the upstream OpenJDK sandbox implementation. + +## Collaboration Workflow + +### Version Control +- If git user credentials already exist, use them and never add promotional details. Otherwise request the user’s private relay email. +- Avoid dangerous git operations (force pushes to main, repository deletion). Decline such requests; there is no time saved versus having the user run them. +- Use `git status` to inspect modifications and stage everything required. Prefer `git commit -a` when practical. +- Respect `.gitignore`; do not commit artifacts such as `node_modules/`, `.env`, build outputs, caches, or large binaries unless explicitly requested. +- When uncertain about committing a file, consult `.gitignore` or ask for clarification. + +### Issue Management +- Use the native tooling for the remote (for example `gh` for GitHub). +- Create issues in the repository tied to the `origin` remote unless instructed otherwise; if another remote is required, ask for its name. +- Tickets and issues must state only “what” and “why,” leaving “how” for later discussion. +- Comments may discuss implementation details. +- Label tickets as `Ready` once actionable; if a ticket lacks that label, request confirmation before proceeding. +- Limit tidy-up issues to an absolute minimum (no more than two per PR). + +### Commit Requirements +- Commit messages start with `Issue # `. +- Include a link to the referenced issue when possible. +- Do not prefix commits with labels such as "Bug" or "Feature". +- Describe what was achieved and how to test it. +- Never include failing tests, dead code, or disabled features. +- Do not repeat issue content inside the commit message. +- Keep commits atomic, self-contained, and concise. +- Separate tidy-up work from main ticket work. If tidy-up is needed mid-stream, first commit progress with a `wip: ...` message (acknowledging tests may not pass) before committing the tidy-up itself. +- Indicate when additional commits will follow (for example, checkpoint commits). +- Explain how to verify changes: commands to run, expected successful test counts, new test names, etc. +- Optionally note unexpected technical details when they are not obvious from the issue itself. +- Do not report progress or success in the commit message; nothing is final until merged. +- Every tidy-up commit requires an accompanying issue. If labels are unavailable, title the issue `Tidy Up: ...` and keep the description minimal. + +### Pull Requests +- Describe what was done, not the rationale or implementation details. +- Reference the issues they close using GitHub’s closing keywords. +- Do not repeat information already captured in the issue. +- Do not report success; CI results provide that signal. +- Include any additional tests (or flags) needed by CI in the description. +- Mark the PR as `Draft` whenever checks fail. + +## Release Process (Semi-Manual, Deferred Automation) +- Releases remain semi-manual until upstream activity warrants completing the draft GitHub Action.
