3.7.0 — 自上一正式版 3.6.0 以来的完整更新

\n

本次正式版整合 3.6.1、3.6.2、3.6.3、3.6.4、3.6.5 和 3.6.6 的全部功能更新与修复。

\n

3.6.1：代码对比显示修复（#1006，修复 #1004）

\n
  • 修复 Monaco 代码对比区域的高度布局，为合并编辑器容器设置高度，恢复对比内容的正常显示。
\n

3.6.2：提交记录布局修复（#1013）

\n
  • 修复题目 ID 为 0、缺少重新提交链接时提交记录的排版错误，避免相关处理打断页面。
  • 安全构造提交记录中的链接，并将缺失链接的判断限定在需要重新提交链接的处理逻辑中。
\n

3.6.3：获取数据功能升级（#1015）

\n
    \n
  • 页面没有数据申请区域时自动创建获取数据控件。
    • \n
  • 默认模式采用 gzip + Base93 压缩传输，逐字节保留任意输入，支持文本、Unicode 和混合内容；无效 UTF-8 以可逆的逐字节转义形式显示。
    • \n
  • 新增可选 NSC3 高速数值模式，压缩 long long 整数及每行数值个数；规范数值输入可恢复空格、空行、换行与末尾换行，非规范或混合内容原样回退。
    • \n
  • 新增“保留换行”选项，默认开启。关闭后，规范数值输入恢复为单行空格分隔数据，降低随机行长带来的输出开销；仅适用于 cin 或 scanf 等不依赖行边界的读取方式，不适用于 getline 或按行解析。
    • \n
  • 界面增加各模式的说明与适用范围，帮助选择通用模式或高速数值模式。
    • \n
  • 生成的数据获取程序先向 stderr 输出并刷新，再通过 abort() 触发运行错误以返回数据；同时兼容读取旧版异常包装结果。
    • \n
\n

3.6.4：提交验证码支持（#1019）

\n
    \n
  • 修复评测队列繁忙、服务端启用验证码时，脚本提交界面丢失验证码字段而导致提交失败的问题。
    • \n
  • 显示验证码图片与输入框，支持点击图片更换、按回车提交，并在提交请求中携带验证码。
    • \n
  • 新增 AutoCaptcha 设置，支持在浏览器本地通过模板匹配识别四位数字验证码，不调用外部 AI 服务。识别不确定时交由用户输入；非四位数字类型提示手动填写。
    • \n
  • 普通提交与强制提交均检查验证码是否为空，并在实际发送请求前再次检查，避免用户中途清空或刷新图片后仍发送空验证码。
    • \n
  • 若服务端在页面加载后才要求验证码，或返回验证码错误，显示并刷新验证码、恢复提交按钮并提示重新填写。
    • \n
\n

3.6.5：比赛结束后回退提交修复（#1021）

\n
    \n
  • 修复比赛结束后向原题回退提交时响应被忽略、提交静默丢失的问题。
    • \n
  • 从比赛题目列表中解析完整原题编号，避免固定截取四位数字造成题号错误。
    • \n
  • 正确处理成功跳转、提交冷却与服务端错误；遇到重复提交限制时按三秒间隔重试，最多尝试五次，并显示进度及失败原因。
    • \n
  • 每次回退请求前重新检查验证码并携带当前输入；验证码失效时刷新图片并要求重新填写。
    • \n
  • 处理比赛页面读取、题目列表解析及提交网络错误，恢复按钮状态，避免一直停留在“正在提交”。
    • \n
\n

3.6.6：验证码自动更换与重试（#1023）

\n
    \n
  • 启用自动识别后，若当前验证码识别不确定，自动更换图片重试，最多尝试五张；仍不确定时提示手动输入或点击换图。
    • \n
  • 换图请求期间暂时锁定输入框，避免用户根据旧图片填写；图片加载完成或请求失败后恢复输入。
    • \n
  • 防止过期异步请求覆盖较新的验证码状态，并避免自动识别覆盖用户已经输入的内容。
    • \n
  • 验证码图片加载失败时给出明确提示，支持点击图片重试。
    • \n
