fix(choro): surface tool errors and incomplete searches by Oscar-Williams · Pull Request #595 · slow-stack/mneme

Oscar-Williams · 2026-11-06T16:44:10Z

Fixes #579.

Summary

DSH showed invalid output when a chorography tool returned a repository or page error. The three tools now use the host's error path and tell callers how to register or select a repository, locate a page, or restore access to its file.

Search keeps matches from readable pages and lists the pages it could not read. If no matches are available and a page could not be read, the tool reports that the search was incomplete.

Validation

The same dispatcher and HTTP tests failed in six cases on 6a521d7 and passed all 16 on this branch. They exercise a registered checkout unavailable on the current machine, unreadable pages, and unknown repository IDs.
The full suite passed on Windows and Ubuntu with Node 22 and 24. Windows skipped the existing symlink case. Both legacy host configurations passed on Ubuntu.
The source and lib sync check, Linux coverage run, and MCP parity tests passed.

I used AI assistance for the patch and regression tests and reviewed every line of the final diff.

Summary by CodeRabbit

功能改进
- 搜索遇到无法读取的页面时，会提示结果可能不完整；如已有匹配结果，仍会保留并显示。
- 页面读取失败时，会区分页面缺失与其他读取问题，并提供相应提示。
- 仓库未登记或仓库选择存在歧义时，会显示错误提示。
文档
- 补充仓库地志工具的启用方式、多仓库选择说明及搜索结果提示。

Walkthrough

此变更调整地志工具的仓库解析和页面读取错误处理。搜索会跳过不可读页面，并在结果中报告遗漏页面；已有命中仍会返回。

Changes: 地志工具错误与搜索

Layer / File(s)	Summary
页面读取错误分类与 API 响应 `lib/wiki/queries.js`, `src/wiki/queries.js`, `lib/api.js`, `src/api.js`, `test/wiki-api.test.js`	查询根据读取错误区分页面缺失和不可读；页面 API 的 409 响应提供对应提示。API 测试覆盖这两类错误。
地志工具错误路径 `lib/tools.js`, `src/tools.js`, `test/wiki-tools.test.js`	仓库解析失败和页面读取失败通过工具错误通道报告。测试通过 Cordis 宿主调用验证工具可用性、仓库选择及错误结果。
不完整搜索结果与说明 `lib/wiki/queries.js`, `src/wiki/queries.js`, `lib/tools.js`, `src/tools.js`, `test/wiki-tools.test.js`, `README.md`, `CHANGELOG.md`	搜索记录不可读页面。存在命中时保留命中并提示遗漏页面；没有命中且存在不可读页面时报告搜索不完整。测试和文档说明相关行为。

Explanation

Docstring coverage is 72.73% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 11 functions across 8 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

补充命中上限后的不可读页面测试。

在 dsh-mneme/test/wiki-tools.test.js 中增加 limit: 1 的宿主测试：先让可读页面产生一个命中，再让排序靠后的页面不可读，并断言返回该页面的 slug 和 Search was incomplete 提示。当前 search 在达到命中上限后立即返回，这个测试可以锁定该边界行为。

达到命中上限后仍需检查剩余页面

当 limit=1 且可读的 a 页先命中时，搜索会立即返回。如果后面的 z 页不可读，结果不会报告该页或提示搜索不完整。请在保留命中上限的同时检查剩余页面，并报告不可读的页。

感谢这个修复，已合并（merge commit b9217635，main CI 全绿）。

合并前我做了一步你没做的事，在此说明：main 在你开 PR 之后又进了两条（#593 pin 修复 → 79d49d29），分支保护是 strict: true（必须 up-to-date），所以 gh pr update-branch 直接报 Cannot update PR branch due to conflicts。冲突只有一个文件 dsh-mneme/CHANGELOG.md 的 ## [Unreleased] 段首（你加 #579 条目、main 加 #593 条目，同位置插入）。

处理方式：在本地把 origin/main merge 进 fix/choro-tool-errors，冲突按「两条都保留、本次的 #579 条目在上」解，产生 merge commit 3d708c7（parents = 你原来的 89d7c70 + main 79d49d29），然后推到了你的 fork 分支 Oscar-Williams/mneme 的 fix/choro-tool-errors（maintainerCanModify 为 true）。代码本身一个字符没动 —— 只动了 CHANGELOG 的冲突段。

验证（在新 head 3d708c7 上）：

定向 node --test test/wiki-tools.test.js test/wiki-api.test.js → 16/16 pass
node scripts/check-sync.js → ✓ src/ 与 lib/ 一致（95 个文件）
CI 13 项：12 pass + osv-scanner skipping（fork PR 的 run 需要维护者手动 approve，已批准后跑完）
相对 main 的改动清单仍是原来那 10 个文件，.mimosa / tools/ / 临时产物 0 命中

如果你的本地分支还在 89d7c70，记得 git fetch + git reset --hard 到新 head，别把 CHANGELOG 那段冲突再手解一遍。
