PID重用防护 - 添加进程启动时间检查，对比文件修改时间避免误删活动进程的日志 - Unix: 通过 /proc//stat 读取进程启动时间 - Windows: 使用 GetProcessTimes API 获取创建时间 - 7天策略: 无法获取进程启动时间时，超过7天的日志视为孤儿 2. 符号链接攻击防护 - 新增安全检查避免删除恶意符号链接 - 使用 os.Lstat 检测符号链接 - 使用 filepath.EvalSymlinks 解析真实路径 - 确保所有文件在 TempDir 内（防止路径遍历） 强烈建议的改进： 3. 异步启动清理 - 通过 goroutine 运行清理避免阻塞主流程启动 4. NotExist错误语义修正 - 文件已被其他进程删除时计入 Kept 而非 Deleted - 更准确反映实际清理行为 - 避免并发清理时的统计误导 5. Windows兼容性验证 - 完善Windows平台的进程时间获取 测试覆盖： - 更新所有测试以适配新的安全检查逻辑 - 添加 stubProcessStartTime 支持PID重用测试 - 修复 setTempDirEnv 解析符号链接避免安全检查失败 - 所有测试通过（codex-wrapper: ok 6.183s） Co-authored-by: Claude Sonnet 4.5 --- codex-wrapper/logger.go | 142 ++++++++++++++++++++++--- codex-wrapper/logger_test.go | 74 +++++++++---- codex-wrapper/main.go | 3 +- codex-wrapper/main_integration_test.go | 25 +++-- codex-wrapper/process_check_unix.go | 74 +++++++++++++ codex-wrapper/process_check_windows.go | 45 +++++++- 6 files changed, 317 insertions(+), 46 deletions(-) diff --git a/codex-wrapper/logger.go b/codex-wrapper/logger.go index 47cacad..446f447 100644 --- a/codex-wrapper/logger.go +++ b/codex-wrapper/logger.go @@ -46,9 +46,12 @@ type CleanupStats struct { } var ( - processRunningCheck = isProcessRunning - removeLogFileFn = os.Remove - globLogFiles = filepath.Glob + processRunningCheck = isProcessRunning + processStartTimeFn = getProcessStartTime + removeLogFileFn = os.Remove + globLogFiles = filepath.Glob + fileStatFn = os.Lstat // Use Lstat to detect symlinks + evalSymlinksFn = filepath.EvalSymlinks ) // NewLogger creates the async logger and starts the worker goroutine. @@ -263,6 +266,9 @@ func (l *Logger) run() { // cleanupOldLogs scans os.TempDir() for codex-wrapper-*.log files and removes those // whose owning process is no longer running (i.e., orphaned logs). +// It includes safety checks for: +// - PID reuse: Compares file modification time with process start time +// - Symlink attacks: Ensures files are within TempDir and not symlinks func cleanupOldLogs() (CleanupStats, error) { var stats CleanupStats tempDir := os.TempDir() @@ -279,30 +285,66 @@ func cleanupOldLogs() (CleanupStats, error) { for _, path := range matches { stats.Scanned++ filename := filepath.Base(path) + + // Security check: Verify file is not a symlink and is within tempDir + if shouldSkipFile, reason := isUnsafeFile(path, tempDir);

<0+swe-agent[bot]@users.noreply.github.com> Date: Mon, 8 Dec 2025 11:12:39 +0800 Subject: [PATCH 4/4] =?UTF-8?q?test:=20=E8=A1=A5=E5=85=85=E6=B5=8B?= =?UTF-8?q?=E8=AF=95=E8=A6=86=E7=9B=96=E6=8F=90=E5=8D=87=E8=87=B3=2089.3%?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 解决的测试盲点： 1. getProcessStartTime (Unix) 0% → 77.3% - 新增 process_check_test.go - 测试 /proc//stat 解析 - 覆盖失败路径和边界情况 2. getBootTime (Unix) 0% → 91.7% - 测试 /proc/stat btime 解析 - 覆盖缺失和格式错误场景 3. isPIDReused 60% → 100% - 新增表驱动测试覆盖所有分支 - file_stat_fails, old_file, new_file, pid_reused, pid_not_reused 4. isUnsafeFile 82.4% → 88.2% - 符号链接检测测试 - 路径遍历攻击测试 - TempDir 外文件测试 5. parsePIDFromLog 86.7% → 100% - 补充边界测试：负数、零、超大 PID 测试质量改进： - 新增 stubFileStat 和 stubEvalSymlinks 辅助函数 - 新增 fakeFileInfo 用于文件信息模拟 - 所有测试独立不依赖真实系统状态 - 表驱动测试模式提升可维护性 覆盖率统计： - 整体覆盖率: 85.5% → 89.3% (+3.8%) - 新增测试代码: ~150 行 - 测试/代码比例: 1.08 (健康水平) Co-authored-by: Claude
