From 1c82d4b51883d42835a42d5c5b04c4a0776d99a1 Mon Sep 17 00:00:00 2001 From: Benoit Chesneau Date: Fri, 3 Apr 2026 09:09:16 +0200 Subject: [PATCH 01/15] Add ASGI test suite enhancement with 134 new tests New test files covering areas identified as gaps compared to Daphne and Uvicorn test coverage: - test_asgi_header_security.py: Header validation, normalization, injection prevention - test_asgi_error_handling.py: Application errors, body receiver errors, graceful shutdown - test_asgi_protocol_http.py: HTTP connection management, chunked encoding, methods, scope building - test_asgi_websocket_enhanced.py: WebSocket message limits, connection rejection, subprotocols - test_asgi_lifespan.py: Lifespan message formats and behavior - test_asgi_forwarded_headers.py:
