Implemented Smart Logging (telemetry) in `Client` and `AsyncClient` to help users debug API requests, generated URLs, and server errors (`404`, `400`, `429`). - Added a new "Logging & Debugging" section to `README.md`. -

Refactored the `Config` routing engine to use a deterministic, data-driven approach (`EXACT_ROUTES` and `PREFIX_ROUTES`) for better maintainability. - Improved dynamic API version resolution for domain endpoints to gracefully switch between `v1`, `v3`, and `v4` for nested resources, with a safe fallback to `v3`. - Secured internal configuration registries by wrapping them in `MappingProxyType` to prevent accidental mutations of the client state. +- Broadened type hints for `files` (`Any | None`) and `timeout` (`int | float | tuple`) to fully support `requests`/`httpx` capabilities (like multipart lists) without triggering false positives in strict IDEs. - Modernized the codebase using modern Python idioms (e.g., `contextlib.suppress`) and resolved strict typing errors for `pyright`. - Updated Dependabot configuration to group minor and patch updates and limit open PRs. +- Migrated the fragmented linting and formatting pipeline (Flake8, Black, Pylint, Pyupgrade, etc.) to a unified, high-performance `ruff` setup in `.pre-commit-config.yaml`. +- Refactored `api_call` exception blocks to use the `else` clause for successful returns, adhering to strict Ruff (TRY300) standards. +- Enabled pip dependency caching in GitHub Actions to drastically speed up CI workflows. ### Fixed +- Fixed a silent data loss bug in `create()` where custom `headers` passed by the user were ignored instead of being merged into the request. +- Fixed a kwargs collision bug in `update()` by using `.pop("headers")` instead of `.get()` to prevent passing duplicate keyword arguments to the underlying request. +- Preserved original tracebacks (PEP 3134) by properly chaining `TimeoutError` and `ApiError` using `from e`. +- Used safely truncating massive HTML error responses to 500 characters (preventing a log-flooding vulnerability (OWASP CWE-532)). +- Replaced a fragile `try/except TypeError` status code check with robust `getattr` and `isinstance` validation to prevent masking unrelated exceptions. - Resolved `httpx` `DeprecationWarning` in `AsyncEndpoint` by properly routing serialized JSON string payloads to the `content` parameter instead of `data`. - Fixed a bug in `domains_handler` where intermediate path segments were sometimes dropped for nested resources like `/credentials` or `/ips`. - Fixed flaky integration tests failing with `429 Too Many Requests` and `403 Limits Exceeded` by adding proper eventual consistency delays and state teardowns. - Fixed DKIM key generation tests to use the `-traditional` OpenSSL flag, ensuring valid PKCS1 format compatibility. - Fixed DKIM selector test names to strictly comply with RFC 6376 formatting (replaced underscores with hyphens). +### Pull Requests Merged + +- [PR_36](https://github.com/mailgun/mailgun-python/pull/36) -

Security guardrail (CWE-319) in `Config` that logs a warning if a cleartext `http://` API URL is configured. - Python 3.14 support to the GitHub Actions test matrix. - Implemented Smart Logging (telemetry) in `Client` and `AsyncClient` to help users debug API requests, generated URLs, and server errors (`404`, `400`, `429`). -- Added a new "Logging & Debugging" section to `README.md`. +- Smart Webhook Routing: Implemented payload-based routing for domain webhooks. The SDK dynamically routes to `v1`, `v3`, or `v4` endpoints based on the HTTP method and presence of parameters like `event_types` or `url`. +- Deprecation Interceptor: Added a registry and interception hook that emits non-breaking `DeprecationWarning`s and logs when utilizing obsolete Mailgun APIs (e.g., v3 validations, legacy tags, v1 bounce-classification). - Added `build_path_from_keys` utility in `mailgun.handlers.utils` to centralize and dry up URL path generation across handlers. - Overrode __dir__ in Client and AsyncClient to expose dynamic endpoint routes (e.g., .messages, .domains) directly to IDE autocompletion engines (VS Code, PyCharm). - Native dynamic routing support for Mailgun Optimize, Validations Service, and Email Preview APIs without requiring new custom handlers. - Advanced path interpolation in `handle_default` to automatically inject inline URL parameters (e.g., `/v2/x509/{domain}/status`). +- Added a new "Logging & Debugging" section to `README.md`. - An intelligent live meta-testing suite (`test_routing_meta_live.py`) to strictly verify SDK endpoint aliases against live Mailgun servers. ### Changed @@ -26,6 +28,8 @@ We [keep a changelog.](http://keepachangelog.com/) - Broadened type hints for `files` (`Any | None`) and `timeout` (`int | float | tuple`) to fully support `requests`/`httpx` capabilities (like multipart lists) without triggering false positives in strict IDEs. - **Performance**: Implemented automated Payload Minification. The SDK now strips structural spaces from JSON payloads (`separators=(',', ':')`), reducing network overhead by ~15-20% for large batch requests. - **Performance**: Memoized internal route resolution logic using `@lru_cache` in `_get_cached_route_data`, eliminating redundant string splitting and dictionary lookups during repeated API calls. +- Replaced flat timeouts with strict `(10.0, 60.0)` connect/read tuple timeouts in both `Endpoint` and `AsyncEndpoint` to enforce fail-fast network resiliency. +- Updated `DOMAIN_ENDPOINTS` mapping to reflect Mailgun's latest architecture, officially moving `tracking`, `click`, `open`, `unsubscribe`, and `webhooks` from `v1` to `v3`. - Modernized the codebase using modern Python idioms (e.g., `contextlib.suppress`) and resolved strict typing errors for `pyright`. - **Documentation**: Migrated all internal and public docstrings from legacy Sphinx/reST format to modern Google Style for cleaner readability and better IDE hover-hints. - Updated Dependabot configuration to group minor and patch updates and limit open PRs. diff --git a/README.md b/README.md index 18b3bd7..ac79057 100644 --- a/README.md +++ b/README.md @@ -3,7 +3,9 @@ Welcome to the official Python SDK for [Mailgun](http://www.mailgun.com/)!
