* bpo-29778: Ensure python3.dll is loaded from correct locations when Python ↵Steve Dower2020-07-061-1/+44
| | | | | | is embedded (GH-21297) Also enables using debug build of `python3_d.dll` Reference: CVE-2020-15523

* bpo-29782: Consolidate _Py_Bit_Length() (GH-20739)Niklas Fiekas2020-06-151-0/+40
| | | | | | | | | | In GH-2866, _Py_Bit_Length() was added to pymath.h for lack of a better location. GH-20518 added a more appropriate header file for bit utilities. It also shows how to properly use intrinsics. This allows reconsidering bpo-29782. * Move the function to the new header. * Changed return type to match __builtin_clzl() and reviewed usage. * Use intrinsics where available. * Pick a fallback implementation suitable for inlining.
* bpo-29882: Add _Py_popcount32() function (GH-20518)Victor Stinner2020-06-081-1/+41
| | | | | | * Rename pycore_byteswap.h to pycore_bitutils.h. * Move popcount_digit() to pycore_bitutils.h as _Py_popcount32(). * _Py_popcount32() uses GCC and clang builtin function if available. * Add unit tests to _Py_popcount32().
* bpo-40602: _Py_hashtable_set() reports rehash failure (GH-20077)Victor Stinner2020-05-141-5/+9
| | | | If _Py_hashtable_set() fails to grow the hash table (rehash), it now fails rather than ignoring the error.
* bpo-40602: Write unit tests for _Py_hashtable_t (GH-20091)Victor Stinner2020-05-141-0/+88
| | | | | | | Cleanup also hashtable.c. Rename _Py_hashtable_t members: * Rename entries to nentries * Rename num_buckets to nbuckets
* bpo-39849: Enable assertions in _testcapimodule.c and _testinternalcapi.c ↵Hai Shi2020-04-201-0/+3

* bpo-40302: Add pycore_byteswap.h header file (GH-19552)Victor Stinner2020-04-171-1/+31
| | | | | | | | | | | | | | Add a new internal pycore_byteswap.h header file with the following functions: * _Py_bswap16() * _Py_bswap32() * _Py_bswap64() Use these functions in _ctypes, sha256 and sha512 modules, and also use in the UTF-32 encoder. sha256, sha512 and _ctypes modules are now built with the internal C API.
* bpo-40241: Add pycore_gc.h header file (GH-19494)Victor Stinner2020-04-131-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | Move the PyGC_Head structure and the following private macros to the internal C API: * _PyGCHead_FINALIZED() * _PyGCHead_NEXT() * _PyGCHead_PREV() * _PyGCHead_SET_FINALIZED() * _PyGCHead_SET_NEXT() * _PyGCHead_SET_PREV() * _PyGC_FINALIZED() * _PyGC_PREV_MASK * _PyGC_PREV_MASK_COLLECTING * _PyGC_PREV_MASK_FINALIZED * _PyGC_PREV_SHIFT * _PyGC_SET_FINALIZED() * _PyObject_GC_IS_TRACKED() * _PyObject_GC_MAY_BE_TRACKED() * _Py_AS_GC(o) Keep the private _PyGC_FINALIZED() macro in the public C API for backward compatibility with Python 3.8: make it an alias to the new PyObject_GC_IsFinalized() function. Move the SIZEOF_PYGC_HEAD constant from _testcapi module to _testinternalcapi module.
* bpo-39947: Move get_recursion_depth() to _testinternalcapi (GH-18974)Victor Stinner2020-03-131-1/+12
| | | | | Move get_recursion_depth() function from _testcapi to _testinternalcapi to avoid accessing PyThreadState attributes directly in _testcapi.
* 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-36635: Add _testinternalcapi module (GH-12841)Victor Stinner2019-04-181-0/+45
Add a new _testinternalcapi module to test the internal C API. Move _Py_GetConfigsAsDict() function to the internal C API: _testembed now uses _testinternalcapi to access the function.
