说明

  • treeCheckable={0} 正常启用复选、多选、级联及显示策略,相关选择回调和禁用判断保持一致。
  • 将 label 展示的本地空值判断统一到 isNonNullable,删除重复 isNil helper。
  • 将 @rc-component/util 最低版本提升到 ^1.13.0,补充模式与零值标签回归测试。

验证

  • npm test -- --runInBand(187 项通过)
  • npm run tsc
  • 改动源码 ESLint 检查通过。
  • 使用本组最新 Tree/Select 源码验证零值复选框、级联、严格模式、禁用节点和 onChange。

Summary by CodeRabbit

  • 修复
    • 改进复选选项和单选值的处理,确保数字 0 等有效 React 内容能正确参与多选、选中策略及标签显示。
    • 更新节点值的空值判断;缺少节点值时仍会在开发环境中发出警告。

Walkthrough

本次更新复选状态的可渲染性判断,并将本地空值判断替换为共享工具。新增测试覆盖 treeCheckable={0} 和 labelInValue 中零值标签的渲染。

Changes

TreeSelect 渲染与空值处理

Layer / File(s) Summary
共享空值判断
package.json、src/utils/valueUtil.ts、src/hooks/useDataEntities.ts、src/TreeSelect.tsx
依赖版本更新为 @rc-component/util ^1.13.0。移除 isNil,并用 isNonNullable 检查节点值及单选值。
复选可渲染性判断
src/TreeSelect.tsx、src/OptionList.tsx、src/utils/warningPropsUtil.ts、tests/renderability.test.tsx
复选状态和相关显示条件改为检查内容是否可渲染。新增测试覆盖零值复选内容及零值标签。

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Suggested reviewers: zombiej

Merge Risk: 🟡 Moderate · up to 3fa22

With the declared Tree version, a zero-valued checkbox does not work as intended. Update the Tree dependency and test the actual checkbox interaction before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 3fa22

The change affects how a public selection control behaves, but the reviewed paths do not introduce a new security boundary or privileged operation. Some behavior depends on external component utilities that could not be fully verified here.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The identified exposure is to applications consuming TreeSelect selection values and callbacks; the inspected flow does not establish a service, tenant, data-store, or credential boundary crossing.

Trust Boundaries and Controls

  • observed — For the checkable path, OptionList returns before forwarding a node that is disabled, has its checkbox disabled, or has checkable set to false. The PR changes when that path applies, not the disabled-node predicate.

让回归测试覆盖 Tree 的复选框交互。

当前测试未传入 open,也未查询 .rc-tree-select-tree-checkbox 或触发 onCheck。它只验证 TreeSelect 的外层多选状态,以及 defaultValue 产生的 B 标签。因此,Tree 将 checkable={0} 当作 false 时,现有断言仍不会失败。

增加真实的复选框渲染断言,并点击父节点验证级联结果:

@rc-component/tree 1.5.3 checkable zero fix @rc-component/select 1.11.0 zero label fix

💡 Result:

These look like version-change notes, but the **`@rc-component/select@1.11.0` release does not list a zero-label fix**—its release note says it fixes option-position announcements in virtual mode. ([github.com](https://github.com/react-component/select/releases?utm_source=openai))

I couldn’t verify from the available release notes what changed in **`@rc-component/tree@1.5.3`** regarding checkable zero values. The package version exists, and its docs describe `checkable` as enabling node checking. ([npmjs.com](https://www.npmjs.com/package/%40rc-component/tree?utm_source=openai))

提升 @rc-component/tree 的最低版本。

@rc-component/tree@1.5.3 使用 if (props.checkable),并将 checkable 强制转换为 !!checkable。因此 treeCheckable={0} 仍会被当作未启用。src/OptionList.tsx 中的 isReactRenderable 不能修复 Tree 内部的转换。

@rc-component/select@1.11.0 已通过数字分支保留标签 0,无需因该问题提升 Select 版本。将 @rc-component/tree 的最低版本提升到包含零值 checkable 修复的已发布版本。
