NeoSetzer 85

v85 — 2026-10-02

主要改进

• 修复多处运行时崩溃：本批崩溃均由新引入的静态检查流程发现，属单元测试覆盖不到的 GTK 运行路径——偏好设置快捷键捕获按下任意键即崩（缺 Gdk 导入）；构建日志行右键菜单弹出即崩（GdkRectangle 不是 PyGObject 暴露的名字，应为 Gdk.Rectangle）；取消「保存构建日志」对话框即崩（except GLib.Error 未导入 GLib）；AI 修复发送后执行阶段崩（agent_runner 为函数局部导入不跨方法共享，提升为模块级导入）。

• 修复解释器缺失弹窗无法操作：latexmk 缺失时弹窗没有任何按钮也无法可靠关闭；现两个分支共用「取消 / 前往偏好设置」响应组。

• 修复预览分段控件全灭态判断：Adw.ToggleGroup 未选中时 get_active() 返回 G_MAXUINT 而非负数，原来的 active < 0 兜底永不成立；改为按档位数判界，恒有一档亮着。

• 恢复失焦时关闭 undo 分组：document controller 中 _on_focus_leave 被后置的空占位实现静默覆盖，删除占位后「切走再切回时 Ctrl+Z 不再作用于上一段连续输入」的行为恢复生效。

• 代码清理：93 个文件清理未使用导入与未用局部变量；测试中行内 open() 改 with 语句消除 ResourceWarning，文档字符串加 r 前缀消除 SyntaxWarning；全仓库通过 ruff check 零告警。

Improvements

• fix: Preference shortcut capture no longer crashes on any keypress (missing Gdk import).
• fix: Build log crashes fixed — row context menu popup (GdkRectangle → Gdk.Rectangle), cancelling "Save log" (unimported GLib.Error), and the AI-fix execute step (agent_runner hoisted to a module-level import).
• fix: Interpreter-missing dialog shares its Cancel / Go-to-Preferences responses across both branches; the latexmk branch previously produced a buttonless dialog that could not reliably be closed.
• fix: Preview segmented control now handles the "no active toggle" state (G_MAXUINT, not negative) by falling back per toggle count.
• fix: Focus-leave closes the undo group again (an empty stub overriding the real implementation was removed).
• refactor: Removed unused imports and locals across 93 files; tests use with-open and raw docstrings (no more ResourceWarning/SyntaxWarning); the repo passes ruff check with zero warnings.
