HitranLab v1.5.4

HitranLab v1.5.4

Release Date: 2026-09-16

---

What's New

Bug Fixes

• Fixed the layer manager falsely reporting "Q(T) / cross-section view" when deleting a curve
• Fixed the duplicated "not configured (not configured)" API key status text
• Fixed the download engine still showing "HAPI2 official API (with api_key)" after clearing the API key: hapi2_bootstrap(force=True) ignored force, and the stale key stayed in SETTINGS; the Clear button now actually revokes the key
• Fixed the status panel never refreshing: it now refreshes when the tab is opened and immediately after saving/clearing the key
• Cross-section API errors are now classified by HTTP status code instead of blaming the user for server-side failures (401/403 → key issue, 404 → not found, 5xx → server fault, URLError → network/proxy, timeout → timeout)
• Fixed "Import spectrum" and "Compute spectrum" silently wiping each other's curves
• Fixed hover readout mislabeling units in sigma mode; imported external data is no longer labeled as alpha
• Fixed merged-CSV header unit mislabeling when the first dataset is imported external data
• Fixed the NumPy 2 deprecation warning from np.trapz
• Added an upper bound to the on-disk computation cache (bounded startup load; oldest entries evicted with their .npz)

Security & Privacy

• Credential redaction: the official v2 API puts the API key in the request URL path, so exception text could leak it into MCP responses, log fields, GUI messages and Hitran_Data/error.log; now scrubbed at all three exits
• Self-update hardening: https-only asset URL, basename-only filename, %% escaping for install paths containing %
• Release privacy gate: numba on-disk caches (.nbc, which embed the builder's absolute path) are stripped before packaging, and the whole artifact is rescanned

Improvements

• Fetch errors are classified: network failures are no longer conflated with "this window has no HITRAN lines"
• Network precheck now validates proxy reachability and reports the exact proxy address

新增内容

问题修复

• 修复「图层管理」删除曲线误报"当前为 Q(T)/截面视图"
• 修复「运行状态」API key 显示"未配置（未配置）"
• 修复取消 API key 后「下载引擎」仍显示 HAPI2 官方 API（两个根因：force 被短路 + key 残留）；「清除」现在真正取消 key
• 修复「运行状态」面板不刷新（切到该页自动刷新；保存/清除 key 后立即刷新）
• 截面接口报错按 HTTP 状态码区分，不再把官方服务端故障栽给用户
• 修复「导入光谱」与「计算光谱」互相清空曲线
• 修复悬停读数在 sigma 模式谎标单位；外部导入数据不再谎标 alpha
• 修复合并导出 CSV 表头单位谎标
• 修复 NumPy 2 下 np.trapz 弃用告警
• 磁盘计算缓存加上限（启动只加载最新若干条，按时间淘汰最旧）

安全与隐私

• 凭据脱敏：官方 v2 API 把 key 放在 URL 路径中，异常文本可能把 key 带进 MCP 响应 / log / GUI 提示 / error.log；现已在三处出口统一脱敏
• 自更新加固：强制 https、文件名只取 basename、对含 % 的安装路径做 %% 转义
• 发布隐私闸门：打包前清除会内嵌构建机绝对路径的 numba 磁盘缓存，并回扫全产物

优化改进

• 取数错误分类：联网失败不再与"该窗口无 HITRAN 收录线"并列
• 网络预检纳入代理连通性，并给出具体代理地址

HitranLab v1.5.3

What's Changed

Bug Fixes

• Introduced task generation checks: stale messages from cancelled worker threads no longer pollute the new task's UI state
• Fixed cross-section file import failure from arbitrary paths: files are now auto-copied into xsc_data/ before import
• Fixed silent isotopologue selection override: line strength mode now correctly passes the isotopologue parameter
• Fixed UI freezing when saving API key: hapi2_bootstrap is now executed on a background thread
• Fixed UI freezing when importing large spectrum files: switched to numpy.loadtxt for batch reading
• Fixed progress bar being updated by cancelled background tasks: progress callbacks now include generation checks

---

本次更新

问题修复

• 引入任务世代校验机制：停止计算后旧线程的残留消息不再污染新任务 UI
• 修复浏览截面文件导入失败：选完文件自动复制到 xsc_data/ 目录
• 修复非主同位素被静默忽略：线强模式正确传递同位素参数
• 修复 API key 保存时阻塞 UI：hapi2_bootstrap 移到后台线程执行
• 修复导入大文件光谱卡死 UI：改用 numpy.loadtxt 批量读取
• 修复进度条被已取消任务继续刷新
