No backward compatibility with the alpha API is provided. The version numbers will now be independent from the spec to provide release independence for the library. ### Breaking Changes -#### Field Rename: `class` → `category` - -The field previously named `class` has been renamed to `category` to align with the official XARF v4 specification. This change was made to avoid conflicts with programming language reserved keywords and better reflect the field's purpose. - -**Impact:** -- All JSON reports must now use `"category"` instead of `"class"` -- Python code must access `report.category` instead of `report.class_` -- Validation checks for `"category"` field presence - -**Migration:** -- Update all JSON generation code to use `"category"` -- Replace all `report.class_` with `report.category` in Python code -- See [MIGRATION_GUIDE.md](docs/MIGRATION_GUIDE.md) for detailed migration instructions - -```python -# Before (v3.x) -report = { - "class": "content", # Old field name - "type": "phishing" -} -print(report.class_) # Awkward Python workaround - -# After (v4.0.0+) -report = { - "category": "content", # New field name - "type": "phishing" -} -print(report.category) # Clean Python access -``` +- **New public API**: `parse()`, `create_report()`, `create_evidence()` are now module-level functions. The `XARFParser` and `XARFGenerator` classes have been removed. +- **Structured result objects**: `parse()` and `create_report()` now return `ParseResult` and `CreateReportResult` dataclasses respectively, rather than bare model instances or dicts. +- **Structured errors**: `ValidationError` and `ValidationWarning` are dataclasses with `field`, `message`, and (for errors) `value` attributes — previously errors were plain strings. +- **Package name**: published as `xarf` (was `xarf-parser`). +- **Python version**: minimum is now 3.10 (was 3.8). ### Added -- **Generator Functionality**: New `XARFGenerator` class for programmatically creating XARF v4 reports - - `create_report()` - Generate complete reports with validation - - `create_messaging_report()` - Generate messaging category reports (spam, phishing) - - `create_connection_report()` - Generate connection category reports (DDoS, port scans) - - `create_content_report()` - Generate content category reports (phishing sites, malware) - - Automatic UUID generation for `report_id` - - Timestamp generation in ISO 8601 format - - Built-in validation during generation - -- **Reporter `on_behalf_of` Field**: Support for infrastructure providers sending reports on behalf of other organizations - - `reporter.on_behalf_of.org` - Organization being represented - - `reporter.on_behalf_of.contact` - Contact email for represented organization - - Useful for MSSPs, abuse reporting services, and infrastructure providers - -- **Enhanced Validation**: Improved validation for all XARF v4 requirements - - Category-specific field validation - - Evidence structure validation - - Reporter information validation - - Timestamp format validation - -- **Python 3.12 Support**: Added support for Python 3.12 - -### Changed - -- **Model Classes**: Updated all model classes to use `category` instead of `class_` - - `XARFReport.category` replaces `XARFReport.class_` - - `MessagingReport.category` replaces `MessagingReport.class_` - - `ConnectionReport.category` replaces `ConnectionReport.class_` - - `ContentReport.category` replaces `ContentReport.class_` - -- **Parser Validation**: Updated validation logic to check for `"category"` field - - Old reports with `"class"` will fail validation - - Use migration helper to convert legacy reports - -- **Field Access**: Removed `class_` aliasing workaround in favor of clean `category` field - - Pydantic models now use `category` directly - - No more Python keyword conflicts - -### Removed - -- **Converter Module**: Temporarily removed `xarf.converter` module for XARF version conversion - - Will be redesigned and re-added in a future release - - Users needing conversion should implement temporary solution (see migration guide) - -- **Python 3.7 Support**: Dropped support for Python 3.7 (EOL June 2023) - - Minimum Python version is now 3.8 - -### Fixed - -- Improved error messages for validation failures -- Better handling of optional fields -- Fixed timezone handling for timestamps - -### Documentation - -- Added comprehensive [MIGRATION_GUIDE.md](docs/MIGRATION_GUIDE.md) with: - - Step-by-step migration instructions - - Before/after code examples - - Common migration issues and solutions - - Database migration examples - - Backward compatibility patterns - -- Updated [README.md](README.md) with: - - Generator usage examples - - Updated JSON examples using `"category"` - - `on_behalf_of` examples - - Security best practices - - Links to xarf.org website - - Updated feature matrix - -### Security - -- Enhanced input validation for all fields -- Added size limits for evidence payloads (5MB per item, 15MB total) -- Improved email validation for reporter contact fields -- Better handling of untrusted input in strict mode - ---- - -## [3.0.0] - 2023-11-15 - -### Added -- Initial XARF v3 support -- Basic JSON parsing and validation -- Support for common abuse types -- Python 3.8+ compatibility +- **All 7 categories fully implemented**: messaging, connection, content, infrastructure, copyright, vulnerability, reputation — with Pydantic v2 discriminated union models covering all 32 report types. +- **Schema-driven validation**: validation rules are derived from the official xarf-spec JSON schemas via `jsonschema` + `referencing` (Draft 2020-12); no hardcoded type or field lists. +- **`SchemaRegistry`**: programmatic access to schema-derived categories, types, and field metadata. Exposed as the `schema_registry` module-level singleton. +- **`SchemaValidator`**: AJV-equivalent JSON Schema validator with strict mode (promotes `x-recommended` fields to required before validation). +- **`create_evidence()`**: helper that computes hash, base64-encodes payload, and records size — supports `sha256`, `sha512`, `sha1`, `md5`. +- **`show_missing_optional`** parameter on `parse()` and `create_report()`: populates `result.info` with missing recommended and optional field details. +- **v3 backward compatibility** fully integrated into `parse()`: automatic detection and conversion with `XARFv3DeprecationWarning`. +- **`python -m xarf fetch-schemas`**: CLI command to pull fresh schemas from the xarf-spec GitHub release. +- **`python -m xarf check-schema-updates`**: CLI command to report whether a newer spec version is available. +- **`py.typed` marker** (PEP 561): downstream `mypy` picks up types when the package is installed. +- **Bundled schemas**: schemas ship inside the wheel, pinned to spec v4.2.0, loaded via `importlib.resources`. ### Changed -- Migrated from XARF v2 to v3 format - ---- - -## [2.1.0] - 2023-06-10 - -### Added -- Evidence attachment support -- Custom field handling - -### Fixed -- Timestamp parsing issues -- Validation edge cases - ---- - -## [2.0.0] - 2023-03-20 - -### Added -- Complete rewrite for XARF v2 -- Pydantic-based models -- JSON Schema validation -- Comprehensive test suite - ---- - -## [1.0.0] - 2022-09-15 - -### Added -- Initial release -- Basic XARF v1 parsing -- Limited validation - ---- - -## Migration Guides - -- **v3.x → v4.0.0**: See [MIGRATION_GUIDE.md](docs/MIGRATION_GUIDE.md) -- **v2.x → v3.x**: Contact support for legacy migration assistance - -## Links - -- [XARF v4 Specification](https://xarf.org/docs/specification/) -- [GitHub Repository](https://github.com/xarf/xarf-parser-python) -- [PyPI Package](https://pypi.org/project/xarf-parser/) -- [Issue Tracker](https://github.com/xarf/xarf-parser-python/issues) -- [XARF Website](https://xarf.org) - -## Versioning -This project follows [Semantic Versioning](https://semver.org/): -- **MAJOR** version for incompatible API changes -- **MINOR** version for backwards-compatible functionality additions -- **PATCH** version for backwards-compatible bug fixes +- **Tooling**: switched to `ruff` (replaces `black`, `isort`, `flake8`); `mypy --strict`; `bandit`; `pytest` with 80% coverage threshold. +- **`v3_compat.py`**: aligned type mappings exactly with the JS reference implementation (8 types, PascalCase + lowercase variants for each). +- **`models.py`**: replaced with result dataclasses (`ParseResult`, `CreateReportResult`, `ValidationError`, `ValidationWarning`) and base Pydantic models (`XARFReport`, `XARFEvidence`, `ContactInfo`). -Alpha releases use suffix: `4.0.0a1`, `4.0.0a2`, etc. -Beta releases use suffix: `4.0.0b1`, `4.0.0b2`, etc. +[Unreleased]: https://github.com/xarf/xarf-python/compare/v0.1.0...HEAD +[0.1.0]: https://github.com/xarf/xarf-python/releases/tag/v0.1.0 diff --git a/CODE_OF_CONDUCT.md b/CODE_OF_CONDUCT.md index 577e221..a2bc02f 100644 --- a/CODE_OF_CONDUCT.md +++ b/CODE_OF_CONDUCT.md @@ -1,48 +1,77 @@ -Contributor Covenant Code of Conduct -Our Pledge +# Contributor Covenant Code of Conduct + +## Our Pledge + We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation. + We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community. -Our Standards + +## Our Standards + Examples of behavior that contributes to a positive environment for our community include: -* Demonstrating empathy and kindness toward other people -* Being respectful of differing opinions, viewpoints, and experiences -* Giving and gracefully accepting constructive feedback -* Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience -* Focusing on what is best not just for us as individuals, but for the overall community +- Demonstrating empathy and kindness toward other people +- Being respectful of differing opinions, viewpoints, and experiences +- Giving and gracefully accepting constructive feedback +- Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience +- Focusing on what is best not just for us as individuals, but for the overall community Examples of unacceptable behavior include: -* The use of sexualized language or imagery, and sexual attention or advances of any kind -* Trolling, insulting or derogatory comments, and personal or political attacks -* Public or private harassment -* Publishing others’ private information, such as a physical or email address, without their explicit permission -* Other conduct which could reasonably be considered inappropriate in a professional setting +- The use of sexualized language or imagery, and sexual attention or advances of any kind +- Trolling, insulting or derogatory comments, and personal or political attacks +- Public or private harassment +- Publishing others' private information, such as a physical or email address, without their explicit permission +- Other conduct which could reasonably be considered inappropriate in a professional setting + +## Enforcement Responsibilities -Enforcement Responsibilities Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful. + Community leaders have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate. -Scope + +## Scope + This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces.
