bengal-pounce 0.3.0

Highlights

• Fast HTTP/1.1 parser — Custom _fast_h1.py replaces h11 on the sync worker hot path. Direct bytes parsing (~3 µs/req vs ~22 µs for h11) with full safety: method validation, header size limits, null byte/control character injection rejection, duplicate Content-Length detection, and request smuggling prevention (RFC 7230 §3.3.3).
• 30k req/s on pure Python — Sync worker throughput now matches uvicorn through fused parsing, shared request pipeline, and single-pass header scanning.
• Shared request pipeline — prepare_request(), negotiate_compressor(), log_request(), and is_trusted_peer() are shared between Worker and SyncWorker for feature parity and code deduplication.

Added

• _fast_h1.py — Fast HTTP/1.1 parser for sync workers
• _headers.py — Shared get_header() consolidates 7 duplicate copies across modules
• _request_pipeline.py — Shared request pipeline for Worker and SyncWorker
• TCP_NODELAY set on accepted connections in accept_distributor.py

Changed

• Middleware classification cached — MiddlewareStack.__init__ classifies middleware once via inspect.signature instead of per-request
• ConnectionClosed → ConnectionCompleted — Lifecycle event renamed for clarity
• trusted_hosts type — Changed from tuple[str, ...] to frozenset[str] for O(1) lookup with pre-computed wildcard flag
• Single-pass header scanning — Response send path detects Content-Length and Transfer-Encoding in one pass
• OpenTelemetry optimizations — Pre-instantiated propagator, filtered to trace headers only
• Static file header extraction — Single pass over request headers
• Shared socket for thread workers — create_listeners(shared=True) avoids macOS SO_REUSEPORT distribution issues
• Server and supervisor simplified — Streamlined lifecycle state machine and worker spawning
