变更说明

禁漫(JM)下载的交付物从「整本一个加密 PDF」改为「每章一份 AES-256 加密 PDF(同一个随机 8 位密码),打包成一个无密码 zip」:多章节本子不再需要一本几十上百 MB 的单文件才能翻开,zip 解压后按文件名就是阅读顺序。

交付结构:

JM1114751 测试本子.zip          ← 无密码,作为独立文件消息发送
├── JM1114751 001 序章.pdf      ← AES-256,密码统一
├── JM1114751 002.pdf
└── JM1114751 003 第三话.pdf

影响范围

用户可见行为

  • 合并转发仍是「本子信息 / 解密密码」两节点,随后单独发一条文件消息——发的是 zip;密码节点措辞改为「zip 内所有 PDF 的解密密码(8 位):…」,避免用户以为 zip 本身要密码。密码仍不进历史摘要。
  • zip 条目为 JM<车号> <三位章节序号>[ <章节标题>].pdf,序号取服务端章节 order 并补零(空章节不占号,服务端没给标题的章节只留序号、不再重复本子标题)。
  • 单章超限只跳过该章、其余章节照常打包,信息节点写明「N 章未打包」;所有章节都没能出 PDF 时仍只发「本子信息 / 状态」两个节点。

破坏性配置变更

  • [jm].max_file_size → [jm].chapter_max_file_size(默认仍 100MB,0 不限、<0 回退 100)。语义从「整本 PDF 上限」变为「单章 PDF 上限」,超限只丢该章;旧键失效并回退默认值,需要用户改配置。zip 总体积 = 章节数 × 单章上限,不再受配置约束(QQ/NapCat 侧上传上限由部署承担)。
  • 同步更新:config.toml.example、docs/configuration.md、docs/pipelines.md、docs/usage.md、docs/development.md、README.md、ARCHITECTURE.md、jm_book 的 README 与 config.json 描述。

内部接口

  • src/Undefined/jm/downloader.py:JmDownload 拆成 JmChapterArchive(zip_path + 每章 ChapterPdfInfo + skipped_chapters,状态 ok/partial/empty)与 JmPlainDownload(uid 路径的单份未加密 PDF);download_book_pdf → download_book,_download_sync 拆成 _download_archive_sync / _download_plain_sync。
  • 逐章组装取代整本组装:每章 download → _write_pdf → 收集,该章页面随即释放(峰值内存 ≈ 一章页面 + 已完成章节 PDF),zip 写完后删掉散落副本,任务目录只留最终交付物;删除「整本源图字节累计超限就中止整本」的预判。
  • src/Undefined/jm/sender.py:_send_result(zip_path=...),build_info_text / build_history_message 收窄为 JmChapterArchive,无密码时状态节点文案由「PDF 未发送」改为「文件未发送」。
  • 投递语义一字未改:文件不进合并转发(转发节点里的文件在 QQ 客户端下载会失败)、转发被明确拒绝才降级为「信息 / 密码」两条普通消息、delivery_uncertain / file_transfer_error 不降级重发但 zip(此前从未发出)照常单独发送、文件自身投递未确认直接上抛。
  • jm_book 的 output_mode=uid 维持单份未加密整本 PDF(供 file_analysis_agent 解析),仅共用新的单章上限校验。
  • v3.18.3 发布准备:CHANGELOG 条目 + 版本号同步(pyproject.toml、src/Undefined/__init__.py、两个 App 的 package/lock/Cargo/tauri.conf 与 uv.lock,lock 只改根包版本、无依赖漂移)。

关联 Issue

无

自检

  • uv run ruff check . 与 uv run ruff format --check . 通过(815 files)
  • uv run mypy . 通过(815 source files,Success)
  • uv run pytest tests/ --cov 通过(覆盖率不低于 pyproject.toml 中的 fail_under)
  • 改动 apps/undefined-console/ 或 src/Undefined/webui/static/js/:已跑 cd apps/undefined-console && npm run check
  • 改动 apps/undefined-chat/:已跑 cd apps/undefined-chat && npm run check
  • 涉及配置项:已同步 config.toml.example 与 docs/configuration.md
  • 涉及 WebUI / Tauri 界面:已附截图

说明:未跑全量 pytest --cov(只跑了受影响模块的测试集:JM 全套 + skills 导入边界 + 配置模板/env/映射 + 管线注册,共 147 passed);两个 App 只有版本号改动,其 Biome / tsc / cargo fmt / check / test 由 pre-commit 全量钩子覆盖并通过。

备注

  • 部署注意:升级后请把 config.toml 里的 [jm].max_file_size 改成 [jm].chapter_max_file_size,否则会静默回退默认 100MB。可用 uv run python scripts/sync_config_template.py 同步模板(旧键不会被自动删除,也不会被读取)。
  • 回滚方式:直接 revert 本 PR 即可,无数据迁移、无 schema 变更;已发出的 zip 与新 PDF 不受影响。
  • 真实链路已验证:真图 → 每章真 PDF → zip,zip 无需密码即可列出/解压,每个章节 PDF 需密码且同一密码可打开。

Summary by CodeRabbit

  • New Features
    • JM book downloads now provide a ZIP containing a separate AES-256-encrypted PDF for each chapter. All PDFs share a password, provided with the book information; the ZIP is sent separately.
    • Chapters that exceed the size limit or cannot produce a PDF are skipped individually; remaining chapters are still delivered, with skipped chapters reported. If none can be included, book information and status are sent without a ZIP or password.
  • Configuration
    • The per-chapter size setting is now chapter_max_file_size (default: 100 MB). Set it to 0 for no limit. The previous setting name is no longer recognized.

禁漫下载的交付物从「整本一个加密 PDF」改为「每章一份加密 PDF,统一密码打包成
一个无密码 zip」:多章节本子不再需要一本几十上百 MB 的单文件才能翻开,zip 解压后
按文件名就是阅读顺序。

- `downloader.py`:`JmDownload` 拆成 `JmChapterArchive`(zip + 每章 PDF 元信息 +
  `skipped_chapters`,状态 `ok`/`partial`/`empty`)与 `JmPlainDownload`(uid 路径的
  单份未加密 PDF),`download_book_pdf` → `download_book`;逐章 `download →
  _write_pdf → 收集`,每章页面在该章写完即释放,zip 写完后删掉散落副本,任务目录
  只留最终交付物。
- zip 条目为 `JM<车号> <三位章节序号>[ <章节标题>].pdf`(序号取服务端章节 `order`,
  空章节不占号),zip 用标准库 `zipfile` + `ZIP_DEFLATED` 写成、不加密;每个章节
  PDF 各自用同一个随机 8 位密码做 AES-256 加密。
- 体积语义改为单章上限:`[jm].max_file_size` 改名为 `[jm].chapter_max_file_size`
  (默认仍 100MB),超限只跳过那一章、其余章节照常打包,信息节点写明「N 章未打包」;
  旧键失效并回退默认值。zip 总体积不再受配置约束。
- `sender.py`:文件消息改发 zip,密码节点写明「zip 内所有 PDF 的解密密码」;投递语义
  不变(文件不进合并转发、转发被明确拒绝才降级两条普通消息、`delivery_uncertain` /
  `file_transfer_error` 不重发但 zip 照常发送、密码不进历史摘要)。
- `jm_book` 工具的 `output_mode=uid` 维持单份未加密 PDF;配置模板、README、
  ARCHITECTURE、docs(configuration / pipelines / usage / development)与工具
  README/config.json 描述同步更新。
- 版本 3.18.2 → 3.18.3。

📝 Walkthrough

Walkthrough

JM send mode now packages separately encrypted chapter PDFs in an unencrypted ZIP. A per-chapter size setting controls PDF output. The sender delivers the ZIP separately from the information-and-password forward. Attachment retrieval continues to use one combined, unencrypted PDF.

Changes

JM chapter archive

Layer / File(s) Summary
Per-chapter size configuration
src/Undefined/config/*, tests/test_jm_config.py, config.toml.example, docs/configuration.md
The JM size setting changes to chapter_max_file_size. It defaults to 100 MB, uses 0 for no limit, and falls back to 100 MB for negative values.
Chapter PDF and ZIP construction
src/Undefined/jm/downloader.py, tests/test_jm_downloader.py, docs/pipelines.md, CHANGELOG.md, README.md, docs/development.md, ARCHITECTURE.md
The downloader creates one encrypted PDF per chapter and packages successful PDFs in an unencrypted ZIP. It skips chapters that produce no usable PDF or exceed the per-chapter limit. Without a password, it creates one combined unencrypted PDF.
Archive delivery and plain-PDF attachment
src/Undefined/jm/sender.py, tests/test_jm_sender.py, src/Undefined/skills/*, docs/usage.md
The sender delivers the ZIP separately from the forward and omits the file and password when no chapter PDFs are produced. Attachment retrieval uses the combined plain-PDF path. Tool descriptions document the updated output.

chapter-processing loop for the download directory and _chapter_pdf_name, so
duplicate chapter orders or titles cannot create duplicate artifact names. Keep
the original chapter_order in ChapterPdfInfo.

Comment thread src/Undefined/jm/downloader.py Outdated
服务端若返回重复的章节序号(异常数据),下载目录与章节 PDF 名都会撞在一起:
`overwrite=False` 会复用前一条章节的图片,zip 里同名的条目也会被后一份覆盖,
两条章节最终只留下一条。

- 章节产物的序号优先仍用服务端 `ChapterBrief.order`(与阅读顺序一致);
  同一次下载内出现重复序号时退回本次的局部序号并记 warn 日志,保证下载目录名与
  zip 条目名唯一。
- `ChapterPdfInfo.order` 保持服务端原始序号不变,去重只影响产物命名。
- 补充回归用例:三章都报同一序号时三份 PDF 都在 zip 里、下载目录互不相同。
