simonw/datasette:原始碼導讀
本頁用語說明
- Entrypoint record(進入點記錄)
- 分析器標記為「程式可能從這裡開始執行」的檔案。附有 __main__ guard 摘錄時,表示檔案裡有 if __name__ == "__main__": 區塊,摘錄顯示它呼叫了什麼;沒有摘錄時,只是依檔名判斷。
- Bounded static execution path(有界靜態執行路徑)
- 不執行程式、直接從原始碼重建出的呼叫鏈,走到固定步數就停。它說明在紙面上能追到多遠,不代表實際執行時會發生什麼。
- Unresolved boundary(未解析邊界)
- 靜態路徑停下的地方:下一個呼叫進入外部函式庫,或不執行就無法確定。這是本次分析的邊界,不是 repository 的缺陷。
- Static relations(靜態關係)
- 在原始碼中找到的呼叫與 import。「external or unresolved」表示指向分析範圍以外。
- Module role(模組角色)
- 分析器依呼叫進出次數推論的檔案標籤(例如 core、entry/orchestration、leaf)。它描述的是在呼叫圖中的位置,不是作者的設計意圖。
- Test-like files(類測試檔案)
- 名稱或位置看起來像測試的檔案。本次分析只計數,不執行。
- Observed · inferred · author-claimed · unresolved
- 每句話的依據:直接讀自分析的檔案;由分析器從檔案推論;repository 作者自述(metadata、README);或本次分析無法確定。
- Verified(已驗證)
- 本頁有兩種用法。在分析器的記錄裡(「verified provenance」「verified entrypoint」),它表示這筆記錄是直接從分析的檔案讀到的,也就是本指南所說的 observed;以進入點來說,就是檔案裡確實有 __main__ guard 的文字。分析器在 2026-10-04 修正後,只有 cli.py、main.py 這類像進入點的檔名、沒有 guard 的檔案,會記為 inferred(推測);在那之前分析的指南仍把這類檔案標成 verified,它依然只是對檔案用途的推測。它不代表程式被執行或測試過。「最後驗證」是這份指南最後一次通過本實驗室檢查的日期,檢查對象是所標示版本的分析記錄,不是對 repository 本身的審查。
怎麼使用這份導讀
這份導讀依據分析器的課程和可依行定位的區塊,提供一條有先後次序的 repository 閱讀順序。導讀裡的行號範圍,來自分析器在有界靜態分析下,為被分析版本記錄的區塊。在這次分析中,區塊是分析器可依行定位的單位,它的說明反映的是靜態推論,而不是動態執行的證明。
第 1 站:定位
先檢視頂層的容器,它們勾勒出橫跨應用程式核心和測試 fixture 的程式碼庫輪廓。
datasette/__main__.py:1-4:moduledatasette/__main__.py,datasette/__main__.py 裡被分析程式碼的檔案層級容器。tests/build_small_spatialite_db.py:1-23:moduletests/build_small_spatialite_db.py,tests/build_small_spatialite_db.py 裡被分析程式碼的檔案層級容器。tests/fixtures.py:1-492:moduletests/fixtures.py,tests/fixtures.py 裡被分析程式碼的檔案層級容器。datasette/app.py:1-3552:moduledatasette/app.py,datasette/app.py 裡被分析程式碼的檔案層級容器。datasette/cli.py:1-918:moduledatasette/cli.py,datasette/cli.py 裡被分析程式碼的檔案層級容器。
第 2 站:執行的故事
順著靜態重建的執行順序,從 main 的呼叫走到命令列的處理。
datasette/__main__.py:3-4:main_guard__main__,控制在直接執行(而不是被 import)時才會跑的程式碼。datasette/cli.py:127-134:functioncli,封裝一個具名的操作,沒有任何已解析的下游關係。datasette/app.py:1-3552:moduledatasette/app.py,datasette/app.py 裡被分析程式碼的檔案層級容器。
靜態執行路徑從 datasette/__main__.py:__main__ 直接追進 datasette/cli.py:cli。
第 3 站:核心程式碼
分析器核心程式碼課程的八個區塊,全都直接位在函式庫程式碼裡。請注意,接下來的函式庫閱讀集是 AI Frontier 實驗室依呼叫次數挑選的,不是分析器的課程。
在 datasette/utils/__init__.py(service 候選,519 個呼入、53 個呼出)裡:
datasette/utils/__init__.py:576-655:functionmake_dockerfile,連到 24 條下游關係。datasette/utils/__init__.py:659-736:functiontemporary_docker_directory,連到 31 條下游關係。
在 datasette/app.py(entry 候選,356 個呼入、197 個呼出)裡:
datasette/app.py:394-3037:classDatasette,把相關的行為歸在同一個類別邊界裡。datasette/app.py:3040-3314:classDatasetteRouter,把相關的行為歸在同一個類別邊界裡。
在 datasette/utils/asgi.py(service 候選,369 個呼入、21 個呼出)裡:
datasette/utils/asgi.py:86-284:classRequest,把相關的行為歸在同一個類別邊界裡。datasette/utils/asgi.py:506-610:classResponse,把相關的行為歸在同一個類別邊界裡。
在 datasette/views/table.py(service 候選,46 個呼入、283 個呼出)裡:
datasette/views/table.py:1956-2436:functiontable_view_data,連到 142 條下游關係。datasette/views/table.py:923-1236:classTableInsertView,把相關的行為歸在同一個類別邊界裡。
第 4 站:修改會波及哪裡
修改程式時,請先檢查這些區塊,因為靜態圖顯示它們在 Python 和用戶端 JavaScript 兩邊都有集中的耦合和下游依賴。
datasette/app.py:394-3037:classDatasette,把相關的行為歸在同一個類別邊界裡。datasette/static/edit-tools.js:2761-3137:functioncreateTableAlterColumnRow,連到 158 條下游關係。datasette/views/table.py:1956-2436:functiontable_view_data,連到 142 條下游關係。datasette/static/edit-tools.js:969-1280:functioncreateTableColumnRow,連到 142 條下游關係。datasette/resources.py:23-41:classTableResource,把相關的行為歸在同一個類別邊界裡。datasette/app.py:2684-2954:functionDatasette._routes,連到 131 條下游關係。
這份導讀看不到的東西
這份導讀嚴格建立在靜態分析上。它無法解析反射、動態 import、執行期依賴注入、monkey-patching 或動態分派這類動態行為。指令和執行流程都沒有驗證,壓縮過的素材在解析時被略過,不確定性課程裡信心值較低的區塊,只能當作有限度的參考。
這次分析無法確定的事
這些是撰寫模型對分析記錄自己的說明。lim_3、exec_* 或 claim_… 這類識別碼指的是那次分析裡的記錄;陳述與依據表引用的也是同一批記錄。
- 靜態分析不解析動態分派、框架在執行期的接線或動態 import。
- 有兩個壓縮過的打包檔只被清點,沒有納入關係擷取。
