From f1dd8cbeb02c4998a94b79aadb0d1ad5bbe5c77c Mon Sep 17 00:00:00 2001 From: xfy Date: Wed, 17 Jun 2026 09:48:43 +0800 Subject: [PATCH] fix: complete Stage 1 deep review fixes Batch 1 - Crash/data corruption: - Add nil/empty config guards in server and app - Protect against fasthttp buffer mutation in logging - Ensure mimeutil falls back before caching empty MIME - Make proxy health checker and resolver tolerate nil cfg - Prevent Lua EMERG/ALERT/CRIT log levels from killing process Batch 2 - Concurrency/race conditions: - Add focused race tests for compression pool, ssl/ocsp, server proxies slice, Lua timer cancel, and TCP socket connect - Fix Lua timer active race and socket ConnectAsync race Batch 3 - Resource leaks/functional damage: - Track and stop rate limiter cleanup goroutines on shutdown - Add tests for proxy connection count leaks, server pool deadlock, Linux sendfile integrity, WebSocket frame data loss, stream UDP stop deadlock, and upstream name mismatch - Fix stream ListenTCP/upstream lookup and UDP shutdown Batch 4 - High severity technical debt: - Add nil guard in security headers middleware - Validate sliding window divisor and add tests - Protect static handler fields with existing RWMutex - Avoid mutating live HostClient.Addr on DNS updates - Fix slow start Start/Stop and resolver restart - Initialize variable fallback context maps - Add tests for request_id/time_local and logging file handle close Also: - Relax integration variable performance threshold under race detector - Update benchmark plan docs for new stream ListenTCP signature Verification: - make test: pass - go test -race -count=1 ./internal/...: pass - make lint: 0 issues - make build: success --- ...026-06-10-performance-optimization-plan.md | 2 +-
