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 Interfaces¶

Python’s Stable ABI allows extensions to be compatible with multiple versions of Python, without recompilation.

There are two Stable ABIs:

• abi3, introduced in Python 3.2, is compatible with non-free-threaded builds of CPython.

• abi3t, introduced in Python 3.15, is compatible with free-threaded builds of CPython. It has stricter API limitations than abi3.

  Added in version 3.15: abi3t was added in PEP 803

It is possible for an extension to be compiled for both abi3 and abi3t at the same time; the result will be compatible with both free-threaded and non-free-threaded builds of Python. Currently, this has no downsides compared to compiling for abi3t only.

Each Stable ABI is versioned using the first two numbers of the Python version. For example, Stable ABI 3.14 corresponds to Python 3.14. An extension compiled for Stable ABI 3.x is ABI-compatible with Python 3.x and above.

Extensions that target a stable ABI must only use a limited subset of the C API. This subset is known as the Limited API; its contents are listed below.

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

On some platforms, Python will look for and load shared library files named with the abi3 or abi3t tag (for example, mymodule.abi3.so). Free-threaded interpreters only recognize the abi3t tag, while non-free-threaded ones will prefer abi3 but fall back to abi3t. Thus, extensions compatible with both ABIs should use the abi3t tag.

Python does not necessarily check that extensions it loads have compatible ABI. Extension authors are encouraged to add a check using the Py_mod_abi slot or the PyABIInfo_Check() function, but the user (or their packaging tool) is ultimately responsible for ensuring that, for example, extensions built for Stable ABI 3.10 are not installed for lower versions of Python.

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

0x30b0000  /* Py_PACK_VERSION(3,11) */
0x30c0000  /* Py_PACK_VERSION(3,12) */
0x30d0000  /* Py_PACK_VERSION(3,13) */
0x30e0000  /* Py_PACK_VERSION(3,14) */
0x30f0000  /* Py_PACK_VERSION(3,15) */
0x3100000  /* Py_PACK_VERSION(3,16) */

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 ABIs, 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 ABIs, or the version-specific ABIs. This is the case with Windows and macOS releases from python.org and many third-party distributors.

ABI Checking¶

Python includes a rudimentary check for ABI compatibility.

This check is not comprehensive. It only guards against common cases of incompatible modules being installed for the wrong interpreter. It also does not take platform incompatibilities into account. It can only be done after an extension is successfully loaded.

Despite these limitations, it is recommended that extension modules use this mechanism, so that detectable incompatibilities raise exceptions rather than crash.

Most modules can use this check via the Py_mod_abi slot and the PyABIInfo_VAR macro, for example like this:

PyABIInfo_VAR(abi_info);

static PyModuleDef_Slot mymodule_slots[] = {
   {Py_mod_abi, &abi_info},
   ...
};

The full API is described below for advanced use cases.

int PyABIInfo_Check(PyABIInfo *info, const char *module_name)¶

Part of the Stable ABI since version 3.15.

Verify that the given info is compatible with the currently running interpreter.

Return 0 on success. On failure, raise an exception and return -1.

If the ABI is incompatible, the raised exception will be ImportError.

The module_name argument can be NULL, or point to a NUL-terminated UTF-8-encoded string used for error messages.

Note that if info describes the ABI that the current code uses (as defined by PyABIInfo_VAR, for example), using any other Python C API may lead to crashes. In particular, it is not safe to examine the raised exception.

Added in version 3.15.

PyABIInfo_VAR(NAME)¶

This macro is available when compiling for the Stable ABI since version 3.15.

Define a static PyABIInfo variable with the given NAME that describes the ABI that the current code will use. This macro expands to:

static PyABIInfo NAME = {
    1, 0,
    PyABIInfo_DEFAULT_FLAGS,
    PY_VERSION_HEX,
    PyABIInfo_DEFAULT_ABI_VERSION
}

Added in version 3.15.

type PyABIInfo¶

Part of the Stable ABI (including all members) since version 3.15.

uint8_t abiinfo_major_version¶

The major version of PyABIInfo. Can be set to:

• 0 to skip all checking, or

• 1 to specify this version of PyABIInfo.

uint8_t abiinfo_minor_version¶

The minor version of PyABIInfo. Must be set to 0; larger values are reserved for backwards-compatible future versions of PyABIInfo.

uint16_t flags¶

This field is usually set to the following macro:

PyABIInfo_DEFAULT_FLAGS¶

Part of the Stable ABI since version 3.15.

Default flags, based on current values of macros such as Py_LIMITED_API and Py_GIL_DISABLED.

Alternately, the field can be set to the following flags, combined by bitwise OR. Unused bits must be set to zero.

ABI variant – one of:

PyABIInfo_STABLE¶

Part of the Stable ABI since version 3.15.

Specifies that Stable ABI is used.

PyABIInfo_INTERNAL¶

Specifies ABI specific to a particular build of CPython. Internal use only.

Free-threading compatibility – one of:

PyABIInfo_FREETHREADED¶

Part of the Stable ABI since version 3.15.

Specifies ABI compatible with free-threaded builds of CPython. (That is, ones compiled with --disable-gil; with t in sys.abiflags)

PyABIInfo_GIL¶

Part of the Stable ABI since version 3.15.

Specifies ABI compatible with non-free-threaded builds of CPython (ones compiled without --disable-gil).

PyABIInfo_FREETHREADING_AGNOSTIC¶

Part of the Stable ABI since version 3.15.

Specifies ABI compatible with both free-threaded and non-free-threaded builds of CPython, that is, both abi3 and abi3t.

uint32_t build_version¶

The version of the Python headers used to build the code, in the format used by PY_VERSION_HEX.

This can be set to 0 to skip any checks related to this field. This option is meant mainly for projects that do not use the CPython headers directly, and do not emulate a specific version of them.

uint32_t abi_version¶

The ABI version.

For Stable ABI, this field should be the value of Py_LIMITED_API or Py_TARGET_ABI3T. If both are defined, use the smaller value. (If Py_LIMITED_API is 3; use Py_PACK_VERSION(3, 2) instead of 3.)

Otherwise, it should be set to PY_VERSION_HEX.

It can also be set to 0 to skip any checks related to this field.

PyABIInfo_DEFAULT_ABI_VERSION¶

Part of the Stable ABI since version 3.15.

The value that should be used for this field, based on current values of macros such as Py_LIMITED_API, PY_VERSION_HEX and Py_GIL_DISABLED.

Added in version 3.15.
