* gh-111506: Implement Py_SET_REFCNT() as opaque function in limited C API ↵Victor Stinner2023-11-031-0/+1
| | | | | | | | (#111508) In the limited C API version 3.13, Py_SET_REFCNT() function is now implemented as an opaque function call. Add _Py_SetRefcnt() to the stable ABI.
* gh-110968: Py_MOD_PER_INTERPRETER_GIL_SUPPORTED was added to 3.12 (#111584)Victor Stinner2023-11-011-2/+2

* gh-90815: Exclude mimalloc .c files from Windows build (#111532)Dino Viehland2023-10-311-0/+3
| | | | * Don't include mimalloc .c's in Windows build * Fix warnings on Windows related to mimalloc
* gh-110481: Implement biased reference counting (gh-110764)Sam Gross2023-10-301-0/+2
|
* 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: Build winsound extension with limited C API (#110978)Victor Stinner2023-10-172-129/+25
| | | Replace type->tp_name with PyType_GetQualName().
* gh-110964: Remove private _PyArg functions (#110966)Victor Stinner2023-10-177-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the following private functions and structures to pycore_modsupport.h internal C API: * _PyArg_BadArgument() * _PyArg_CheckPositional() * _PyArg_NoKeywords() * _PyArg_NoPositional() * _PyArg_ParseStack() * _PyArg_ParseStackAndKeywords() * _PyArg_Parser structure * _PyArg_UnpackKeywords() * _PyArg_UnpackKeywordsWithVararg() * _PyArg_UnpackStack() * _Py_ANY_VARARGS() Changes: * Python/getargs.h now includes pycore_modsupport.h to export functions. * clinic.py now adds pycore_modsupport.h when one of these functions is used. * Add pycore_modsupport.h includes when a C extension uses one of these functions. * Define Py_BUILD_CORE_MODULE in C extensions which now include directly or indirectly (via code generated by Argument Clinic) pycore_modsupport.h: * _csv * _curses_panel * _dbm * _gdbm * _multiprocessing.posixshmem * _sqlite.row * _statistics * grp * resource * syslog * _testcapi: bad_get() no longer uses METH_FASTCALL calling convention but METH_VARARGS. Replace _PyArg_UnpackStack() with PyArg_ParseTuple(). * _testcapi: add PYTESTCAPI_NEED_INTERNAL_API macro which is defined by _testcapi sub-modules which need the internal C API (pycore_modsupport.h): exceptions.c, float.c, vectorcall.c, watchers.c. * Remove Include/cpython/modsupport.h header file. Include/modsupport.h no longer includes the removed header file. * Fix mypy clinic.py
* 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

* 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-83180: Made launcher treat shebang 'python' tags as low priority so that ↵Steve Dower2023-10-021-6/+32
| | | | active virtual environments are preferred (GH-108101)
* 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-108996: fix and enable test_msvcrt (#109226)AN Long2023-09-222-1/+106
| | | | | | * Add _testconsole.flush_console_input_buffer() function. * test_kbhit(), test_getwch() and test_getwche() now call flush_console_input_buffer(). * Don't override sys.stdin anymore (not needed).
* gh-74481: Add missing debug function docs and constants to msvcrt (GH-109650)AN Long2023-09-211-0/+4
|
* 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-109266: Fix msvcrt.kbhit's documented return value (GH-109267)AN Long2023-09-122-4/+4

* gh-107603: Argument Clinic: Only include pycore_gc.h if needed (#108726)Victor Stinner2023-08-315-24/+14
| | | | | | | | | | | | | | | | | | | | Argument Clinic now only includes pycore_gc.h if PyGC_Head is needed, and only includes pycore_runtime.h if _Py_ID() is needed. * Add 'condition' optional argument to Clinic.add_include(). * deprecate_keyword_use() includes pycore_runtime.h when using the _PyID() function. * Fix rendering of includes: comments start at the column 35. * Mark PC/clinic/_wmimodule.cpp.h and "Objects/stringlib/clinic/*.h.h" header files as generated in .gitattributes. Effects: * 42 header files generated by AC no longer include the internal C API, instead of 4 header files before. For example, Modules/clinic/_abc.c.h no longer includes the internal C API. * Fix _testclinic_depr.c.h: it now always includes pycore_runtime.h to get _Py_ID().
* gh-108635: Make parameters of some implementations of special methods ↵Serhiy Storchaka2023-08-292-33/+8

* gh-106320: Remove private _PyLong converter functions (#108499)Victor Stinner2023-08-261-1/+2
| | | | | | | | | | | Move these private functions to the internal C API (pycore_long.h): * _PyLong_UnsignedInt_Converter() * _PyLong_UnsignedLongLong_Converter() * _PyLong_UnsignedLong_Converter() * _PyLong_UnsignedShort_Converter() Argument Clinic now emits #include "pycore_long.h" when these functions are used.
* gh-108444: Argument Clinic uses PyLong_AsInt() (#108458)Victor Stinner2023-08-243-27/+27
| | | | Argument Clinic now uses the new public PyLong_AsInt(), rather than the old name _PyLong_AsInt().
* 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-106869: Use new PyMemberDef constant names (#106871)Victor Stinner2023-07-251-2/+2

* 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.
* gh-86493: Use PyModule_Add() instead of PyModule_AddObjectRef() (GH-106860)Serhiy Storchaka2023-07-182-22/+5
|
* 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

* gh-102304: Fix Py_INCREF() stable ABI in debug mode (#104763)Victor Stinner2023-06-061-2/+0
| | | | | | | | | | | When Python is built in debug mode (if the Py_REF_DEBUG macro is defined), the Py_INCREF() and Py_DECREF() function are now always implemented as opaque functions to avoid leaking implementation details like the "_Py_RefTotal" variable or the _Py_DecRefTotal_DO_NOT_USE_THIS() function. * Remove _Py_IncRefTotal_DO_NOT_USE_THIS() and _Py_DecRefTotal_DO_NOT_USE_THIS() from the stable ABI. * Remove _Py_NegativeRefcount() from limited C API.

* gh-92536: Argument Clinic no longer emits PyUnicode_READY() (#105208)Victor Stinner2023-06-013-15/+3
| | | | | | Since Python 3.12, PyUnicode_READY() does nothing and always returns 0. Argument Clinic now also checks for .cpp files (PC/_wmimodule.cpp).
* gh-105156: Argument Clinic avoids Py_UNICODE type (#105161)Victor Stinner2023-05-312-80/+72
| | | | Argument Clinic now uses "const wchar_t*" type instead of "const Py_UNICODE*" type for the "Py_UNICODE" format.
* gh-102304: Fix 2 New Stable ABI Functions (gh-104762)Eric Snow2023-05-301-0/+2
