C API 穩定性
************

除非有另外記錄於文件，Python 的 C API 被包含在向後相容性策略 **PEP
387** 中。大多數改動都是相容於原始碼的（通常只會增加新的 API）。更改現
有 API 或刪除 API 僅在棄用期後或修復嚴重問題時進行。

CPython 的應用程式二進位介面 (Application Binary Interface, ABI) 在次
要版本中是向前和向後相容的（如果它們以相同的方式編譯；請參閱下面的平台
注意事項）。因此，為 Python 3.10.0 編譯的程式碼將能夠在 3.10.8 上運行
，反之亦然，但 3.9.x 和 3.11.x 就需要分別編譯。

C API 有兩層級，有不同的穩定性期望：

* 不穩定 API，可能會在次要版本中發生變化，而沒有棄用階段。會在名稱中以
  "PyUnstable" 前綴來標記。

* 受限 API，在多個次要版本之間相容。當有定義 "Py_LIMITED_API" 時，只有
  這個子集會從 "Python.h" 公開。

下面將更詳細地討論這些內容。

帶有底線前綴的名稱是私有 API (private API)，像是 "_Py_InternalState"，
即使在補丁版本 (patch release) 中也可能被更改，不會另行通知。如果你需
要使用這個 API，可以聯繫 CPython 開發者 並針對你的使用方法來討論是否新
增公開的 API。


不穩定的 C API
==============

任何以 "PyUnstable" 前綴命名的 API 都會公開 CPython 實作細節，並可能在
每個次要版本中進行更改（例如從 3.9 到 3.10），而不會出現任何棄用警告。
但是它不會在錯誤修復發布版本中發生變化（例如從 3.10.0 到 3.10.1）。

它通常用於專門的低階工具，例如偵錯器。

使用此 API 的專案應該要遵循 CPython 開發細節，並花費額外的力氣來針對這
些變動來做調整。


穩定的應用程式二進位介面
========================

為簡單起見，本文件討論*擴充 (extension)*，但受限 API 和穩定 ABI 在所有
API 使用方式中都以相同的方式運作 -- 例如在嵌入式 Python (embedding
Python) 中。


受限 C API
----------

Python 3.2 引入了*受限 API (Limited API)*，它是 Python C API 的一個子
集。僅使用受限 API 的擴充可以只編譯一次就被載入於多個版本的 Python。受
限 API 的內容列在下方。

Py_LIMITED_API

   在包含 "Python.h" 之前定義此巨集以選擇只使用受限 API，並挑選受限
   API 版本。

   將 "Py_LIMITED_API" 定義為對應於你的擴充有支援的最低 Python 版本的
   "PY_VERSION_HEX" 值。該擴充與從指定版本開始的所有 Python 3 版本之
   ABI 相容，並且可以使用過去版本有引入的受限 API。

   與其直接使用 "PY_VERSION_HEX" 巨集，不如寫死 (hardcode) 最小次要版
   本（例如代表 Python 3.10 的 "0x030A0000"），以便在使用未來的 Python
   版本進行編譯時仍保持穩定性。

   你還可以將 "Py_LIMITED_API" 定義為 "3"，這與 "0x03020000"（Python
   3.2，引入了受限 API 的版本）相同。


穩定 ABI
--------

為了實現它，Python 提供了一個*穩定 ABI (Stable ABI)*：一組將在各個
Python 3.x 版本之間保持 ABI 相容的符號。

備註:

  穩定 ABI 可以防止 ABI 問題，例如由於結構布局或函式簽名變化導致缺少符
  號或數據損壞的鏈接器 (linker) 錯誤。然而，Python 的其他變化可能會改
  變 *行為* 的擴充。有關詳細信息，請參閱 Python 的向後相容性政策
  (**PEP 387**)。

穩定 ABI 被包含在受限 API 中開放的符號，但也包含其他符號 - 例如，支援
舊版受限 API 所必需的函式。

在 Windows 上，使用穩定 ABI 的擴充應該連接到 "python3.dll" 而不是特定
版本的函式庫，例如 "python39.dll"。

在某些平台上，Python 將查找並加載以 "abi3" 標籤命名的共享函式庫檔案（
例如 "mymodule.abi3.so"）。它不檢查此類擴充是否符合穩定的 ABI。確保的
責任在使用者（或者打包工具）身上，例如使用 3.10+ 受限 API 建置的擴充不
會為較低版本的 Python 所安裝。

穩定 ABI 中的所有函式都作為函式存在於 Python 的共享函式庫中，而不僅是
作為巨集。這使得它們可被用於不使用 C 預處理器 (preprocessor) 的語言。


受限 API 範圍和性能
-------------------

受限 API 的目標是允許使用完整的 C API 進行所有可能的操作，但可能會降低
性能。

例如，雖然 "PyList_GetItem()" 可用，但它的「不安全」巨集變體
"PyList_GET_ITEM()" 為不可用。巨集運行可以更快，因為它可以依賴 list 物
件的特定版本實作細節。

如果沒有定義 "Py_LIMITED_API"，一些 C API 函式將被嵌入或被替換為巨集。
定義 "Py_LIMITED_API" 會禁用嵌入，從而隨著 Python 資料結構的改進而提高
穩定性，但可能會降低性能。

透過省略 "Py_LIMITED_API" 定義，可以使用特定版本的 ABI 編譯受限 API 擴
充。這可以提高該 Python 版本的性能，但會限制相容性。使用
"Py_LIMITED_API" 編譯將產生一個擴充，可以在特定版本的擴充不可用的地方
發布 — 例如，用於即將發布的 Python 版本的預發布版本 (prerelease)。


受限 API 注意事項
-----------------

請注意，使用 "Py_LIMITED_API" 進行編譯*不*完全保證程式碼符合受限 API
或穩定 ABI。"Py_LIMITED_API" 僅涵蓋定義，但 API 還包括其他議題，例如預
期的語義 (semantic)。

"Py_LIMITED_API" 無法防範的一個問題是使用在較低 Python 版本中無效的引
數來呼叫函式。例如一個開始接受 "NULL" 作為引數的函式。在 Python 3.9 中
，"NULL" 現在代表選擇預設行為，但在 Python 3.8 中，引數將被直接使用，
導致 "NULL" 取消參照 (dereference) 且崩潰 (crash)。類似的引數適用於結
構 (struct) 的欄位。

另一個問題是，當有定義 "Py_LIMITED_API" 時，一些結構欄位目前不會被隱藏
，即使它們是受限 API 的一部分。

出於這些原因，我們建議要以它支援的*所有*次要 Python 版本來測試擴充，並
且最好使用*最低*版本進行建置。

我們也建議要查看所有使用過的 API 的文件，檢查它是否明確屬於受限 API。
即使有定義 "Py_LIMITED_API"，一些私有聲明也會因為技術原因（或者甚至是
無意地，例如臭蟲）而被公開出來。

另請注意，受限 API 不一定是穩定的：在 Python 3.8 中使用
"Py_LIMITED_API" 進行編譯意味著擴充將能以 Python 3.12 運行，但不一定能
以 Python 3.12 *編譯*。特別是如果穩定 ABI 保持穩定，部分受限 API 可能
會被棄用和刪除。


平台注意事項
============

ABI 穩定性不僅取決於 Python，還取決於使用的編譯器、低階函式庫和編譯器
選項。出於穩定 ABI 的目的，這些細節定義了一個「平台」。它們通常取決於
作業系統種類和處理器架構

每個特定的 Python 發布者都有責任確保特定平台上的所有 Python 版本都以不
破壞穩定 ABI 的方式建置。"python.org" 和許多第三方發布者發布的 Windows
和 macOS 版本就是這種情況。
