v0.3.0

This release updates Envoy to 1.37.0. This allows us to use new dynamic modules ABIs to implement response backpressure with Envoy's flow control, the last remaining feature for full production-readiness. With this, pyvoy should generally be complete, with full implementations of ASGI and WSGI and features and controls needed for production. There are also a few additional enhancements and small bug fixes.

📈 Enhancements

• Implements response backpressure by delaying completion of application write / send requests when above the response buffer watermark
• Exposes quic listener port programatically, generally for cases where tls_port = 0 for automatic detection, resulting in separate ports for TCP and UDP
• If TLS keys passed to the CLI do not correspond to a filesystem path, they are handled as raw certificates instead of as paths
• Programmatic setup of pyvoy will fail if Envoy fails to startup. To access logs for this failure case, it becomes necessary to setup PyvoyServer without a context manager. Accessing logs programmatically will usually only be useful for pyvoy's own unit tests.

🛠️ Bug fixes

• IPv6 addresses are properly handled for scope values like server
• WSGI header values containing unicode are now presented with latin1 bytes as required rather than utf-8
