This PR contains the following updates:

Package Change Age Confidence
ruff (source, changelog) >=0.15.18>=0.15.20
ty (changelog) >=0.0.51>=0.0.54, !=0.0.55

Release Notes

  • ty 0.0.55 is excluded after reproducing a regression in generic match/__match_args__ type inference that affected this repository.
  • The temporary code workaround was reverted, and the formatting issue in tests/test_watchfs.py was fixed so CI can pass while still allowing future Renovate updates past 0.0.55.

@copilot 处理一下 CI 报错吧

已处理,修复提交是 250f18a。我定位到 CI 是 ty 升级后对 Result 的类型收窄更严格导致 lint 失败,现已改为显式类型解包;本地已通过 uv run ty check --error-on-warning src/watchfs testsuv run ruff check .uv run pytest

@copilot 说实话,当前这种改动有点不太能接受了,况且 CI 还是挂的

话说 ty 0.0.55 的改动是引入 bug 了么?还是我们的写法问题?如果是 ty 的 bug 我觉得可以抽一个最小复现样例,对比 0.0.54 和 0.0.55,看看两边 reveal_type 分别是啥,另外也调研下 ty 的 issue,看看有没有线程 issue?

已改成回退 workaround,并在 8005336 里把 ty 约束改为 <0.0.55,保留 ruff 更新。当前这次 CI 真正挂的是格式检查:tests/test_watchfs.py 没有过 ruff format --check;我已经一并修掉并本地通过 ty / ruff / pytest

关于 ty:更像是上游在泛型 + match/__match_args__ 上的回归,不是这边业务逻辑必须改写。最小复现里,0.0.54 的 reveal_typemapping -> objectbidirectional -> objecterr -> ValueError | Unknown;到 0.0.55 会退化成全部 Unknown。对应到仓库原写法,0.0.54 下旧代码可以过,0.0.55 会开始把 case Ok((mapping, ...)) 里的绑定值判成 object/Unknown,于是报属性和 append 类型错误。

我查到的相关线程有:astral-sh/ty#887(Advanced pattern matching support,总问题)、#3694(generic union alias + __match_args__ 的 match 推断问题),另外 #2814 也说明过泛型收窄到 Unknown 的类似现象。

另外,推送后新开的两个 workflow run 目前是 action_required,不是代码执行失败:Lint and Format 28462377413、Unit Test 28462377456。

@copilot 0.0.54 怎么过的确认下,是不是因为推成 Any 了?

确实像 astral-sh/ty#3694

会,<0.0.55 的确会把后续 ty 版本一起挡住。已在 e32bdf8 改成只排除 0.0.55ty>=0.0.54,!=0.0.55,这样当前坏版本还会被跳过,但 Renovate 后面仍然能继续提 0.0.56+ 的更新。当前本地也已重新通过 uv run ty check --error-on-warning src/watchfs testsuv run ruff check .uv run pytest

...

我刚复现确认了:0.0.54 能过,基本就是因为它把这里收窄成了 Unknown,不是精确推断对了。Unknown 在 ty 里是比较接近 Any/gradual top 的,所以 mapping.source 这类访问不会继续报错;到 0.0.55 这里变成了 object,于是才开始报属性访问和 append 的类型错误。

我用当前仓库代码做了最小改动复现:在 tests/test_watchfs.pycase Ok((mapping, bidirectional)) 里插 reveal_type,0.0.54 的输出是 mapping -> Unknownbidirectional -> Unknown,0.0.55 则是 mapping -> objectbidirectional -> object。所以结论可以认为是:0.0.54 确实是被 Any-like 地“放过去了”。

另外我也顺手确认了当前分支状态:最新的 Lint and Format / Unit Test workflow 都已经是 success,本地 uv run ty check --error-on-warning src/watchfs testsuv run ruff check .uv run pytest 也通过了。
