refactor(handler/http): split handler monolith into 7 focused files with 96 unit tests
Extract the 1024-line handler.go into concern-focused files:
util.go — 5 pure functions (decodeServerName, basicProxyAuth, upgradeType,
normalizeHostPort, buildConnectResponse) — 100% coverage
auth.go — authenticate (5 probe-resistance strategies + knock) + checkRateLimit
connect.go — handleConnect, sniffAndHandle, dial, setupTrafficLimiter
proxy.go — handleProxy keep-alive loop, proxyRoundTrip, handleUpgradeResponse
websocket.go — WebSocket frame sniffing/recording with rate-limited sampling
udp.go — UDP-over-HTTP relay with SOCKS5 tunnel
metadata.go — metadata struct, parseMetadata, probeResistance type
Key improvements:
- Transport injection (http.RoundTripper field) enables testing without real network
- Nil Router guards in dial, handleUDP, and nil Addr guard in checkRateLimit
- Pure functions converted from methods to package-level (no state dependency)
- setupTrafficLimiter returns cleanup closure to preserve defer lifetime
- handleConnect accepts caller's resp for correct recorder status capture
- Comprehensive package doc with full request-flow documentation
96 tests: 100% on pure functions, 86% on metadata parsing, 55% overall (integration
paths verified by e2e tests).
