C API Stability
***************

Unless documented otherwise, Python’s C API is covered by the
Backwards Compatibility Policy, **PEP 387**. Most changes to it are
source-compatible (typically by only adding new API). Changing
existing API or removing API is only done after a deprecation period
or to fix serious issues.

CPython’s Application Binary Interface (ABI) is forward- and
backwards-compatible across a minor release (if these are compiled the
same way; see Platform Considerations below). So, code compiled for
Python 3.10.0 will work on 3.10.8 and vice versa, but will need to be
compiled separately for 3.9.x and 3.11.x.

There are two tiers of C API with different stability expectations:

* Unstable API, may change in minor versions without a deprecation
  period. It is marked by the "PyUnstable" prefix in names.

* Limited API, is compatible across several minor releases. When
  "Py_LIMITED_API" is defined, only this subset is exposed from
  "Python.h".

These are discussed in more detail below.

Names prefixed by an underscore, such as "_Py_InternalState", are
private API that can change without notice even in patch releases. If
you need to use this API, consider reaching out to CPython developers
to discuss adding public API for your use case.


Unstable C API
==============

Any API named with the "PyUnstable" prefix exposes CPython
implementation details, and may change in every minor release (e.g.
from 3.9 to 3.10) without any deprecation warnings. However, it will
not change in a bugfix release (e.g. from 3.10.0 to 3.10.1).

It is generally intended for specialized, low-level tools like
debuggers.

Projects that use this API are expected to follow CPython development
and spend extra effort adjusting to changes.


Stable Application Binary Interface
===================================

For simplicity, this document talks about *extensions*, but the
Limited API and Stable ABI work the same way for all uses of the API –
for example, embedding Python.


Limited C API
-------------

Python 3.2 introduced the *Limited API*, a subset of Python’s C API.
Extensions that only use the Limited API can be compiled once and be
loaded on multiple versions of Python. Contents of the Limited API are
listed below.

Py_LIMITED_API

   Define this macro before including "Python.h" to opt in to only use
   the Limited API, and to select the Limited API version.

   Define "Py_LIMITED_API" to the value of "PY_VERSION_HEX"
   corresponding to the lowest Python version your extension supports.
   The extension will be ABI-compatible with all Python 3 releases
   from the specified one onward, and can use Limited API introduced
   up to that version.

   Rather than using the "PY_VERSION_HEX" macro directly, hardcode a
   minimum minor version (e.g. "0x030A0000" for Python 3.10) for
   stability when compiling with future Python versions.

   You can also define "Py_LIMITED_API" to "3". This works the same as
   "0x03020000" (Python 3.2, the version that introduced Limited API).


Stable ABI
----------

To enable this, Python provides a *Stable ABI*: a set of symbols that
will remain ABI-compatible across Python 3.x versions.

Note:

  The Stable ABI prevents ABI issues, like linker errors due to
  missing symbols or data corruption due to changes in structure
  layouts or function signatures. However, other changes in Python can
  change the *behavior* of extensions. See Python’s Backwards
  Compatibility Policy (**PEP 387**) for details.

The Stable ABI contains symbols exposed in the Limited API, but also
other ones – for example, functions necessary to support older
versions of the Limited API.

On Windows, extensions that use the Stable ABI should be linked
against "python3.dll" rather than a version-specific library such as
"python39.dll".

On some platforms, Python will look for and load shared library files
named with the "abi3" tag (e.g. "mymodule.abi3.so"). It does not check
if such extensions conform to a Stable ABI. The user (or their
packaging tools) need to ensure that, for example, extensions built
with the 3.10+ Limited API are not installed for lower versions of
Python.

All functions in the Stable ABI are present as functions in Python’s
shared library, not solely as macros. This makes them usable from
languages that don’t use the C preprocessor.


Limited API Scope and Performance
---------------------------------

The goal for the Limited API is to allow everything that is possible
with the full C API, but possibly with a performance penalty.

For example, while "PyList_GetItem()" is available, its “unsafe” macro
variant "PyList_GET_ITEM()" is not. The macro can be faster because it
can rely on version-specific implementation details of the list
object.

Without "Py_LIMITED_API" defined, some C API functions are inlined or
replaced by macros. Defining "Py_LIMITED_API" disables this inlining,
allowing stability as Python’s data structures are improved, but
possibly reducing performance.

By leaving out the "Py_LIMITED_API" definition, it is possible to
compile a Limited API extension with a version-specific ABI. This can
improve performance for that Python version, but will limit
compatibility. Compiling with "Py_LIMITED_API" will then yield an
extension that can be distributed where a version-specific one is not
available – for example, for prereleases of an upcoming Python
version.


Limited API Caveats
-------------------

Note that compiling with "Py_LIMITED_API" is *not* a complete
guarantee that code conforms to the Limited API or the Stable ABI.
"Py_LIMITED_API" only covers definitions, but an API also includes
other issues, such as expected semantics.

One issue that "Py_LIMITED_API" does not guard against is calling a
function with arguments that are invalid in a lower Python version.
For example, consider a function that starts accepting "NULL" for an
argument. In Python 3.9, "NULL" now selects a default behavior, but in
Python 3.8, the argument will be used directly, causing a "NULL"
dereference and crash. A similar argument works for fields of structs.

Another issue is that some struct fields are currently not hidden when
"Py_LIMITED_API" is defined, even though they’re part of the Limited
API.

For these reasons, we recommend testing an extension with *all* minor
Python versions it supports, and preferably to build with the *lowest*
such version.

We also recommend reviewing documentation of all used API to check if
it is explicitly part of the Limited API. Even with "Py_LIMITED_API"
defined, a few private declarations are exposed for technical reasons
(or even unintentionally, as bugs).

Also note that the Limited API is not necessarily stable: compiling
with "Py_LIMITED_API" with Python 3.8 means that the extension will
run with Python 3.12, but it will not necessarily *compile* with
Python 3.12. In particular, parts of the Limited API may be deprecated
and removed, provided that the Stable ABI stays stable.


Platform Considerations
=======================

ABI stability depends not only on Python, but also on the compiler
used, lower-level libraries and compiler options. For the purposes of
the Stable ABI, these details define a “platform”. They usually depend
on the OS type and processor architecture

It is the responsibility of each particular distributor of Python to
ensure that all Python versions on a particular platform are built in
a way that does not break the Stable ABI. This is the case with
Windows and macOS releases from "python.org" and many third-party
distributors.
