| | | | | | | | | | | | * gh-110850: Add PyTime_t C API Add PyTime_t API: * PyTime_t type. * PyTime_MIN and PyTime_MAX constants. * PyTime_AsSecondsDouble(), PyTime_Monotonic(), PyTime_PerfCounter() and PyTime_GetSystemClock() functions. Co-authored-by: Victor Stinner <vstinner@python.org>
* gh-112026: Add again <unistd.h> include in Python.h (#112046)Victor Stinner2023-11-151-3/+12
| | | | Add again <ctype.h> and <unistd.h> includes in Python.h, but don't include them in the limited C API version 3.13 and newer.
* gh-108765: Python.h no longer includes <stddef.h> on Windows (#111563)Victor Stinner2023-10-311-3/+0
| | | | In practice, only Windows is impacted, because the HAVE_STDDEF_H macro was only defined on Windows.
* gh-108724: Add PyMutex and _PyParkingLot APIs (gh-109344)Sam Gross2023-09-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | PyMutex is a one byte lock with fast, inlineable lock and unlock functions for the common uncontended case. The design is based on WebKit's WTF::Lock. PyMutex is built using the _PyParkingLot APIs, which provides a cross-platform futex-like API (based on WebKit's WTF::ParkingLot). This internal API will be used for building other synchronization primitives used to implement PEP 703, such as one-time initialization and events. This also includes tests and a mini benchmark in Tools/lockbench/lockbench.py to compare with the existing PyThread_type_lock. Uncontended acquisition + release: * Linux (x86-64): PyMutex: 11 ns, PyThread_type_lock: 44 ns * macOS (arm64): PyMutex: 13 ns, PyThread_type_lock: 18 ns * Windows (x86-64): PyMutex: 13 ns, PyThread_type_lock: 38 ns PR Overview: The primary purpose of this PR is to implement PyMutex, but there are a number of support pieces (described below). * PyMutex: A 1-byte lock that doesn't require memory allocation to initialize and is generally faster than the existing PyThread_type_lock. The API is internal only for now. * _PyParking_Lot: A futex-like API based on the API of the same name in WebKit. Used to implement PyMutex. * _PyRawMutex: A word sized lock used to implement _PyParking_Lot. * PyEvent: A one time event. This was used a bunch in the "nogil" fork and is useful for testing the PyMutex implementation, so I've included it as part of the PR. * pycore_llist.h: Defines common operations on doubly-linked list. Not strictly necessary (could do the list operations manually), but they come up frequently in the "nogil" fork.

* gh-108765: Python.h no longer includes <ctype.h> (#108831)Victor Stinner2023-09-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | Remove <ctype.h> in C files which don't use it; only sre.c and _decimal.c still use it. Remove _PY_PORT_CTYPE_UTF8_ISSUE code from pyport.h: * Code added by commit b5047fd01948ab108edcc1b3c2c901d915814cfd in 2004 for MacOSX and FreeBSD. * Test removed by commit 52ddaefb6bab1a74ecffe8519c02735794ebfbe1 in 2007, since Python str type now uses locale independent functions like Py_ISALPHA() and Py_TOLOWER() and the Unicode database. Modules/_sre/sre.c replaces _PY_PORT_CTYPE_UTF8_ISSUE with new functions: sre_isalnum(), sre_tolower(), sre_toupper(). Remove unused includes: * _localemodule.c: remove <stdio.h>. * getargs.c: remove <float.h>. * dynload_win.c: remove <direct.h>, it no longer calls _getcwd() since commit fb1f68ed7cc1536482d1debd70a53c5442135fe2 (in 2001).

| | | | | | | | | | | | * Move <ctype.h>, <limits.h> and <stdarg.h> standard includes to Python.h. * Move "pystats.h" include from object.h to Python.h. * Remove redundant "pymem.h" include in objimpl.h and "pyport.h" include in pymem.h; Python.h already includes them earlier. * Remove redundant <wchar.h> include in unicodeobject.h; Python.h already includes it. * Move _SGI_MP_SOURCE define from Python.h to pyport.h. * pycore_condvar.h includes explicitly <unistd.h> for the _POSIX_THREADS macro.
* gh-106320: Remove private _PyTraceMalloc C API functions (#106324)Victor Stinner2023-07-021-1/+1
| | | | | | | * Remove private _PyTraceMalloc C API functions: move them to the internal C API. * Don't export most of these functions anymore, but still export _PyTraceMalloc_GetTraceback() used by tests. * Rename Include/tracemalloc.h to Include/cpython/tracemalloc.h
* gh-106316: Remove pytime.h header file (#106317)Victor Stinner2023-07-011-1/+0
| | | | | | | | | | | | | | | | | Remove the "cpython/pytime.h" header file: it only contained private functions. Move functions to the internal pycore_time.h header file. Move tests from _testcapi to _testinternalcapi. Rename also test methods to have the same name than tested C functions. No longer export these functions: * _PyTime_Add() * _PyTime_As100Nanoseconds() * _PyTime_FromMicrosecondsClamp() * _PyTime_FromTimespec() * _PyTime_FromTimeval() * _PyTime_GetPerfCounterWithInfo() * _PyTime_MulDiv()

* bpo-35134: Remove the Include/code.h header file (GH-32385)Victor Stinner2022-04-071-1/+1
| | | | | | Remove the Include/code.h header file. C extensions should only include the main <Python.h> header file. Python.h includes directly Include/cpython/code.h instead.
* bpo-45459: Add pytypedefs.h header file (GH-31527)Victor Stinner2022-02-241-0/+1
| | | | | | | | | | | | | | | | | | Move forward declarations of Python C API types to a new pytypedefs.h header file to solve interdependency issues between header files. pytypedefs.h contains forward declarations of the following types: * PyCodeObject * PyFrameObject * PyGetSetDef * PyInterpreterState * PyLongObject * PyMemberDef * PyMethodDef * PyModuleDef * PyObject * PyThreadState * PyTypeObject
* bpo-45459: Rename buffer.h to pybuffer.h (#31201)Victor Stinner2022-02-221-1/+1
| | | | | | | | | Rename Include/buffer.h header file to Include/pybuffer.h to avoid conflicts with projects having an existing "buffer.h" header file. * Incude pybuffer.h before object.h in Python.h. * Remove #include "buffer.h" from Include/cpython/object.h. * Add a forward declaration of the PyObject type in pybuffer.h to fix an inter-dependency issue.

* bpo-39026: Fix Python.h when building with Xcode (GH-29488)Victor Stinner2021-11-231-1/+1
| | | | Fix Python.h to build C extensions with Xcode: remove a relative include from Include/cpython/pystate.h.
* bpo-45434: Only exclude <stdlib.h> in Python 3.11 limited C API (GH-29027)Victor Stinner2021-10-191-4/+6
| | | | | | | The Python 3.11 limited C API no longer includes stdlib.h, stdio.h, string.h and errno.h. * Exclude Py_MEMCPY() from Python 3.11 limited C API. * xxlimited C extension is now built with Python 3.11 limited C API.
* bpo-45482: Rename namespaceobject.h to pycore_namespace.h (GH-28975)Victor Stinner2021-10-151-1/+0
| | | | | | | | | Rename Include/namespaceobject.h to Include/internal/pycore_namespace.h. The _testmultiphase extension is now built with the Py_BUILD_CORE_MODULE macro defined to access _PyNamespace_Type. object.c: remove unused "pycore_context.h" include.
* bpo-45434: Remove Include/eval.h header file (GH-28973)Victor Stinner2021-10-151-1/+0
| | | | Move Include/eval.h content into Include/ceval.h and Include/cpython/ceval.h, and remove Include/eval.h.
* bpo-35134: Move classobject.h to Include/cpython/ (GH-28968)Victor Stinner2021-10-151-5/+5
| | | | | | | | | Move classobject.h, context.h, genobject.h and longintrepr.h header files from Include/ to Include/cpython/. Remove redundant "#ifndef Py_LIMITED_API" in context.h. Remove explicit #include "longintrepr.h" in C files. It's not needed, Python.h already includes it.
* bpo-35134: Move Include/cellobject.h to Include/cpython/ (GH-28964)Victor Stinner2021-10-151-1/+1

* bpo-43774: Remove unused PYMALLOC_DEBUG macro (GH-25711)Victor Stinner2021-04-291-9/+0
| | | Enhance also the documentation of debug hooks on memory allocators.
* bpo-43244: Remove the pyarena.h header (GH-25007)Victor Stinner2021-03-241-1/+0
| | | | | | | | | | | | | | | | | | Remove the pyarena.h header file with functions: * PyArena_New() * PyArena_Free() * PyArena_Malloc() * PyArena_AddPyObject() These functions were undocumented, excluded from the limited C API, and were only used internally by the compiler. Add pycore_pyarena.h header. Rename functions: * PyArena_New() => _PyArena_New() * PyArena_Free() => _PyArena_Free() * PyArena_Malloc() => _PyArena_Malloc() * PyArena_AddPyObject() => _PyArena_AddPyObject()
* bpo-43244: Remove parser_interface.h header file (GH-25001)Victor Stinner2021-03-241-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | Remove parser functions using the "struct _mod" type, because the AST C API was removed: * PyParser_ASTFromFile() * PyParser_ASTFromFileObject() * PyParser_ASTFromFilename() * PyParser_ASTFromString() * PyParser_ASTFromStringObject() These functions were undocumented and excluded from the limited C API. Add pycore_parser.h internal header file. Rename functions: * PyParser_ASTFromFileObject() => _PyParser_ASTFromFile() * PyParser_ASTFromStringObject() => _PyParser_ASTFromString() These functions are no longer exported (replace PyAPI_FUNC() with extern). Remove also _PyPegen_run_parser_from_file() function. Update test_peg_generator to use _PyPegen_run_parser_from_file_pointer() instead.
* bpo-35134: Move non-limited C API files to Include/cpython/ (GH-24561)Nicholas Sim2021-02-191-5/+5
| | | | | | Include/{odictobject.h,parser_interface.h,picklebufobject.h,pydebug.h,pyfpe.h} into Include/cpython/. Parser: peg_api: include Python.h instead of parser_interface.h.
* bpo-35134: Move Include/{pyarena.h,pyctype.h} to Include/cpython/ (GH-24550)Nicholas Sim2021-02-171-2/+2
| | | | Move non-limited C API headers pyarena.h and pyctype.h into Include/cpython/ directory.
* bpo-35134, Include: Move pytime.h to cpython/pytime.h (GH-23988)Nicholas Sim2021-02-161-1/+1
| | | | This change is backward compatible since C extension modules must not include "pytime.h" directly, but only include "Python.h".
* bpo-40939: Rename PyPegen* functions to PyParser* (GH-21016)Lysandros Nikolaou2020-06-211-0/+1
| | | | | | Rename PyPegen* functions to PyParser*, so that we can remove the old set of PyParser* functions that were using the old parser.
* bpo-40421: Add Include/cpython/code.h header file (GH-19756)Victor Stinner2020-04-281-0/+1
| | | | | | | | | | | bpo-35134, bpo-40421: Add Include/cpython/code.h header file. code.h now defines PyCodeObject type in the limited C API. It is now included by Python.h. Give a name to the PyCodeObject structure: it is now called "struct PyCodeObject". So it becomes possible to define PyCodeObject as "struct PyCodeObject" in the limited C API without defining the structure.
* bpo-40421: Add pyframe.h header file (GH-19755)Victor Stinner2020-04-281-0/+1
| | | | | | | | | | Add a new separated pyframe.h header file of the PyFrame public C API: it is included by Python.h. Add PyFrame_GetLineNumber() to the limited C API. Replace "struct _frame" with "PyFrameObject" in header files. PyFrameObject is now defined as struct _frame by pyframe.h which is included early enough in Python.h.
* bpo-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-151-0/+1
| | | | Remove explicit pythread.h includes: it is always included by Python.h.
* bpo-39481: Implementation for PEP 585 (#18239)Guido van Rossum2020-04-071-0/+1
| | | | | | | | | | | | This implements things like `list[int]`, which returns an object of type `types.GenericAlias`. This object mostly acts as a proxy for `list`, but has attributes `__origin__` and `__args__` that allow recovering the parts (with values `list` and `(int,)`. There is also an approximate notion of type variables; e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`. Type variables are objects of type `typing.TypeVar`.
* bpo-35081: Move dtoa.h header to the internal C API (GH-18489)Victor Stinner2020-02-121-1/+0
| | | | | | | Move the dtoa.h header file to the internal C API as pycore_dtoa.h: it only contains private functions (prefixed by "_Py"). The math and cmath modules must now be compiled with the Py_BUILD_CORE macro defined.
* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add a whole new documentation page: "Python Initialization Configuration" * PyWideStringList_Append() return type is now PyStatus, instead of int * PyInterpreterState_New() now calls PyConfig_Clear() if PyConfig_InitPythonConfig() fails. * Rename files: * Python/coreconfig.c => Python/initconfig.c * Include/cpython/coreconfig.h => Include/cpython/initconfig.h * Include/internal/: pycore_coreconfig.h => pycore_initconfig.h * Rename structures * _PyCoreConfig => PyConfig * _PyPreConfig => PyPreConfig * _PyInitError => PyStatus * _PyWstrList => PyWideStringList * Rename PyConfig fields: * use_module_search_paths => module_search_paths_set * module_search_path_env => pythonpath_env * Rename PyStatus field: _func => func * PyInterpreterState: rename core_config field to config * Rename macros and functions: * _PyCoreConfig_SetArgv() => PyConfig_SetBytesArgv() * _PyCoreConfig_SetWideArgv() => PyConfig_SetArgv() * _PyCoreConfig_DecodeLocale() => PyConfig_SetBytesString() * _PyInitError_Failed() => PyStatus_Exception() * _Py_INIT_ERROR_TYPE_xxx enums => _PyStatus_TYPE_xxx * _Py_UnixMain() => Py_BytesMain() * _Py_ExitInitError() => Py_ExitStatusException() * _Py_PreInitializeFromArgs() => Py_PreInitializeFromBytesArgs() * _Py_PreInitializeFromWideArgs() => Py_PreInitializeFromArgs() * _Py_PreInitialize() => Py_PreInitialize() * _Py_RunMain() => Py_RunMain() * _Py_InitializeFromConfig() => Py_InitializeFromConfig() * _Py_INIT_XXX() => _PyStatus_XXX() * _Py_INIT_FAILED() => _PyStatus_EXCEPTION() * Rename 'err' PyStatus variables to 'status' * Convert RUN_CODE() macro to config_run_code() static inline function * Remove functions: * _Py_InitializeFromArgs() * _Py_InitializeFromWideArgs() * _PyInterpreterState_GetCoreConfig()

* bpo-36142: Exclude coreconfig.h from Py_LIMITED_API (GH-12111)Victor Stinner2019-03-011-1/+1
| | | | | | | | | The whole coreconfig.h header is now excluded from Py_LIMITED_API. Move functions definitions into a new internal pycore_coreconfig.h header. * Move Include/coreconfig.h to Include/cpython/coreconfig.h * coreconfig.h header is now excluded from Py_LIMITED_API * Move functions to pycore_coreconfig.h
* bpo-28503: Use crypt_r() when available instead of crypt() (GH-11373)Gregory P. Smith2018-12-301-0/+10
| | | | | Use crypt_r() when available instead of crypt() in the crypt module. As a nice side effect: This also avoids a memory sanitizer flake as clang msan doesn't know about crypt's internal libc allocated buffer.
* bpo-35214: Add _Py_ prefix to MEMORY_SANITIZER def. (GH-10503)Gregory P. Smith2018-11-131-2/+2
| | | | Rename our new MEMORY_SANITIZER define to _Py_MEMORY_SANITIZER. Project based C Preprocessor namespacing at its finest. :P
