* gh-120389: Add PyLong_FromInt64() and PyLong_AsInt64() (#120390)Victor Stinner2024-08-281-0/+8
| | | | | | | | | | | | Add new functions to convert C <stdint.h> numbers from/to Python int: * PyLong_FromInt32() * PyLong_FromUInt32() * PyLong_FromInt64() * PyLong_FromUInt64() * PyLong_AsInt32() * PyLong_AsUInt32() * PyLong_AsInt64() * PyLong_AsUInt64()
* gh-105201: Add PyIter_NextItem() (#122331)Erlend E. Aasland2024-08-072-0/+5
| | | | | | | | | Return -1 and set an exception on error; return 0 if the iterator is exhausted, and return 1 if the next item was fetched successfully. Prefer this API to PyIter_Next(), which requires the caller to use PyErr_Occurred() to differentiate between iterator exhaustion and errors. Co-authered-by: Irit Katriel <iritkatriel@yahoo.com>

* gh-120600: Make Py_TYPE() opaque in limited C API 3.14 (#120601)Victor Stinner2024-06-181-0/+1
| | | | In the limited C API 3.14 and newer, Py_TYPE() is now implemented as an opaque function call to hide implementation details.
* gh-74929: PEP 667 C API documentation (gh-119379)Alyssa Coghlan2024-06-011-0/+32
| | | | | | | | * Add docs for new APIs * Add soft-deprecation notices * Add What's New porting entries * Update comments referencing `PyFrame_LocalsToFast()` to mention the proxy instead * Other related cleanups found when looking for refs to the deprecated APIs
* gh-74929: Implement PEP 667 (GH-115153)Tian Gao2024-05-041-0/+3

* gh-117987: Restore several functions removed in Python 3.13 alpha 1 (GH-117993)Victor Stinner2024-04-181-0/+4
| | | | | | | | | Restore these functions removed in Python 3.13 alpha 1: * Py_SetPythonHome() * Py_SetProgramName() * PySys_SetArgvEx() * PySys_SetArgv()
* gh-117929: Restore removed PyEval_InitThreads() function (#117931)Victor Stinner2024-04-171-0/+1

* gh-116936: Add PyType_GetModuleByDef() to the limited C API (#116937)Victor Stinner2024-03-251-0/+1
|
* gh-115754: Add Py_GetConstant() function (#116883)Victor Stinner2024-03-211-0/+2
| | | | | | | | | | | | Add Py_GetConstant() and Py_GetConstantBorrowed() functions. In the limited C API version 3.13, getting Py_None, Py_False, Py_True, Py_Ellipsis and Py_NotImplemented singletons is now implemented as function calls at the stable ABI level to hide implementation details. Getting these constants still return borrowed references. Add _testlimitedcapi/object.c and test_capi/test_object.py to test Py_GetConstant() and Py_GetConstantBorrowed() functions.

* gh-114329: Add `PyList_GetItemRef` function (GH-114504)Sam Gross2024-02-022-0/+5
| | | | | | | The new `PyList_GetItemRef` is similar to `PyList_GetItem`, but returns a strong reference instead of a borrowed reference. Additionally, if the passed "list" object is not a list, the function sets a `TypeError` instead of calling `PyErr_BadInternalCall()`.

| | | | | | | | | | | | | | | | | | | | | * Revert "gh-111089: Use PyUnicode_AsUTF8() in Argument Clinic (#111585)" This reverts commit d9b606b3d04fc56fb0bcc479d7d6c14562edb5e2. * Revert "gh-111089: Use PyUnicode_AsUTF8() in getargs.c (#111620)" This reverts commit cde1071b2a72e8261ca66053ef61431b7f3a81fd. * Revert "gh-111089: PyUnicode_AsUTF8() now raises on embedded NUL (#111091)" This reverts commit d731579bfb9a497cfb0076cb6b221058a20088fe. * Revert "gh-111089: Add PyUnicode_AsUTF8() to the limited C API (#111121)" This reverts commit d8f32be5b6a736dc2fc9dca3f1bf176c82fc9b44. * Revert "gh-111089: Use PyUnicode_AsUTF8() in sqlite3 (#111122)" This reverts commit 37e4e20eaa8f27ada926d49e5971fecf0477ad26.
* gh-111089: Add PyUnicode_AsUTF8() to the limited C API (#111121)Victor Stinner2023-10-201-0/+1
| | | | | | | | Add PyUnicode_AsUTF8() function to the limited C API. multiprocessing posixshmem now uses PyUnicode_AsUTF8() instead of PyUnicode_AsUTF8AndSize(): the extension is built with the limited C API. The function now raises an exception if the filename contains an embedded null character instead of truncating silently the filename.
* gh-85283: Add PySys_Audit() to the limited C API (#108571)Victor Stinner2023-10-171-0/+2
| | | | | | | | | | The PySys_Audit() function was added in Python 3.8 by the PEP 578 "Python Runtime Audit Hooks". Add also PySys_AuditTuple() to the limited C API, function added to Python 3.13. Move non-limited "PerfMap" C API from Include/sysmodule.h to Include/cpython/sysmodule.h.
* gh-85283: Add PyMem_RawMalloc() to the limited C API (#108570)Victor Stinner2023-10-171-0/+4
| | | | | | | | | Add PyMem_RawMalloc(), PyMem_RawCalloc(), PyMem_RawRealloc() and PyMem_RawFree() to the limited C API. These functions were added by Python 3.4 and are needed to port stdlib extensions to the limited C API, like grp and pwd. Co-authored-by: Erlend E. Aasland <erlend@python.org>
* gh-110289: C API: Add PyUnicode_EqualToUTF8() and ↵Serhiy Storchaka2023-10-111-0/+2
| | | | PyUnicode_EqualToUTF8AndSize() functions (GH-110297)
* gh-110397: Add Py_IsFinalizing() to the stable ABI (#110441)Victor Stinner2023-10-071-0/+1

* gh-110014: Remove PY_TIMEOUT_MAX from limited C API (#110217)Victor Stinner2023-10-021-1/+0
| | | | | | | | If the timeout is greater than PY_TIMEOUT_MAX, PyThread_acquire_lock_timed() uses a timeout of PY_TIMEOUT_MAX microseconds, which is around 280.6 years. This case is unlikely and limiting a timeout to 280.6 years sounds like a reasonable trade-off. The constant PY_TIMEOUT_MAX is not used in PyPI top 5,000 projects.
* gh-110014: Fix _POSIX_THREADS and _POSIX_SEMAPHORES usage (#110139)Victor Stinner2023-09-301-0/+1
| | | | | | | | | | | | | | | | * pycore_pythread.h is now the central place to make sure that _POSIX_THREADS and _POSIX_SEMAPHORES macros are defined if available. * Make sure that pycore_pythread.h is included when _POSIX_THREADS and _POSIX_SEMAPHORES macros are tested. * PY_TIMEOUT_MAX is now defined as a constant, since its value depends on _POSIX_THREADS, instead of being defined as a macro. * Prevent integer overflow in the preprocessor when computing PY_TIMEOUT_MAX_VALUE on Windows: replace "0xFFFFFFFELL * 1000 < LLONG_MAX" with "0xFFFFFFFELL < LLONG_MAX / 1000". * Document the change and give hints how to fix affected code. * Add an exception for PY_TIMEOUT_MAX name to smelly.py * Add PY_TIMEOUT_MAX to the stable ABI
* gh-108511: Add C API functions which do not silently ignore errors (GH-109025)Serhiy Storchaka2023-09-171-0/+4
| | | | | | | | | Add the following functions: * PyObject_HasAttrWithError() * PyObject_HasAttrStringWithError() * PyMapping_HasKeyWithError() * PyMapping_HasKeyStringWithError()
* gh-108444: Add PyLong_AsInt() public function (#108445)Victor Stinner2023-08-241-0/+1
| | | | | | * Rename _PyLong_AsInt() to PyLong_AsInt(). * Add documentation. * Add test. * For now, keep _PyLong_AsInt() as an alias to PyLong_AsInt().
* gh-106004: Add PyDict_GetItemRef() function (#106005)Victor Stinner2023-07-211-0/+2
| | | | | * Add PyDict_GetItemRef() and PyDict_GetItemStringRef() functions. Add these functions to the stable ABI version 3.13. * Add unit tests on the PyDict C API in test_capi.
* bpo-42327: C API: Add PyModule_Add() function (GH-23443)Serhiy Storchaka2023-07-181-0/+1
| | | | | It is a fixed implementation of PyModule_AddObject() which consistently steals reference both on success and on failure.
* gh-106307: C API: Add PyMapping_GetOptionalItem() function (GH-106308)Serhiy Storchaka2023-07-111-0/+2
| | | | Also add PyMapping_GetOptionalItemString() function.
* gh-106521: Add PyObject_GetOptionalAttr() function (GH-106522)Serhiy Storchaka2023-07-111-0/+2
| | | | | | It is a new name of former _PyObject_LookupAttr(). Add also PyObject_GetOptionalAttrString().
* gh-106572: Convert PyObject_DelAttr() to a function (#106611)Victor Stinner2023-07-111-0/+2
| | | | | | | | * Convert PyObject_DelAttr() and PyObject_DelAttrString() macros to functions. * Add PyObject_DelAttr() and PyObject_DelAttrString() functions to the stable ABI. * Replace PyObject_SetAttr(obj, name, NULL) with PyObject_DelAttr(obj, name).
* gh-105927: Add PyWeakref_GetRef() function (#105932)Victor Stinner2023-06-212-0/+5
| | | | Add tests on PyWeakref_NewRef(), PyWeakref_GetObject(), PyWeakref_GET_OBJECT() and PyWeakref_GetRef().
* Add Py_TYPE() to Doc/data/refcounts.dat (#105949)Victor Stinner2023-06-201-0/+3
|
* gh-105922: Add PyImport_AddModuleRef() function (#105923)Victor Stinner2023-06-202-0/+4
| | | | | | * Add tests on PyImport_AddModuleRef(), PyImport_AddModule() and PyImport_AddModuleObject(). * pythonrun.c: Replace Py_XNewRef(PyImport_AddModule(name)) with PyImport_AddModuleRef(name).
* gh-85275: Remove old buffer APIs (#105137)Inada Naoki2023-06-022-19/+0
| | | | | They are now abi-only. Co-authored-by: Victor Stinner <vstinner@python.org>
* gh-105182: Remove PyEval_AcquireLock() and PyEval_InitThreads() (#105183)Victor Stinner2023-06-012-10/+0
| | | | | | | | | | | | Remove functions in the C API: * PyEval_AcquireLock() * PyEval_ReleaseLock() * PyEval_InitThreads() * PyEval_ThreadsInitialized() But keep these functions in the stable ABI. Mention "make regen-limited-abi" in "make regen-all".
* gh-105107: Remove PyCFunction_Call() function (#105181)Victor Stinner2023-06-011-1/+0
| | | | | * Keep the function in the stable ABI. * Add unit tests on PyCFunction_Call() since it remains supported in the stable ABI.
* gh-105156: Cleanup usage of old Py_UNICODE type (#105158)Victor Stinner2023-06-011-40/+20
| | | | | | | | | | | | * refcounts.dat: * Remove Py_UNICODE functions. * Replace Py_UNICODE argument type with wchar_t. * _PyUnicode_ToLowercase(), _PyUnicode_ToUppercase(), _PyUnicode_ToTitlecase() are no longer deprecated in comments. It's no longer needed since they now use Py_UCS4 type, rather than the deprecated Py_UNICODE type. * gdb: Remove unused char_width() method.
* gh-105145: Remove old functions to config Python init (#105154)Victor Stinner2023-06-011-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the following old functions to configure the Python initialization, deprecated in Python 3.11: * PySys_AddWarnOptionUnicode() * PySys_AddWarnOption() * PySys_AddXOption() * PySys_HasWarnOptions() * PySys_SetArgvEx() * PySys_SetArgv() * PySys_SetPath() * Py_SetPath() * Py_SetProgramName() * Py_SetPythonHome() * Py_SetStandardStreamEncoding() * _Py_SetProgramFullPath() Most of these functions are kept in the stable ABI, except: * Py_SetStandardStreamEncoding() * _Py_SetProgramFullPath() Update Doc/extending/embedding.rst and Doc/extending/extending.rst to use the new PyConfig API. _testembed.c: * check_stdio_details() now sets stdio_encoding and stdio_errors of PyConfig. * Add definitions of functions removed from the API but kept in the stable ABI. * test_init_from_config() and test_init_read_set() now use PyConfig_SetString() instead of PyConfig_SetBytesString(). Remove _Py_ClearStandardStreamEncoding() internal function.
* gh-105107: Remove PyEval_CallFunction() function (#105108)Victor Stinner2023-05-311-3/+0
| | | | | | | | | | | | | | Remove 4 functions from the C API, deprecated in Python 3.9: * PyEval_CallObjectWithKeywords() * PyEval_CallObject() * PyEval_CallFunction() * PyEval_CallMethod() Keep 3 functions in the stable ABI: * PyEval_CallObjectWithKeywords() * PyEval_CallFunction() * PyEval_CallMethod()
