* bpo-41100: Support macOS 11 and Apple Silicon (GH-22855)Ronald Oussoren2020-11-081-10/+32
| | | | | | | | | | | Co-authored-by: Lawrence D’Anna <lawrence_danna@apple.com> * Add support for macOS 11 and Apple Silicon (aka arm64) As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy * Support building on recent versions of macOS while deploying to older versions This allows building installers on macOS 11 while still supporting macOS 10.9.
* bpo-40910: Export Py_GetArgcArgv() function (GH-20721)Victor Stinner2020-06-081-1/+1
| | | | | | | | | | | | Export explicitly the Py_GetArgcArgv() function to the C API and document the function. Previously, it was exported implicitly which no longer works since Python is built with -fvisibility=hidden. * Add PyConfig._orig_argv member. * Py_InitializeFromConfig() no longer calls _PyConfig_Write() twice. * PyConfig_Read() no longer initializes Py_GetArgcArgv(): it is now _PyConfig_Write() responsibility. * _PyConfig_Write() result type becomes PyStatus instead of void. * Write an unit test on Py_GetArgcArgv().
* bpo-35890: Use RegQueryInfoKeyW and CryptAcquireContextW explicitly (GH-19974)Minmin Gong2020-05-181-2/+2

* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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-36763: Add _PyInitError functions (GH-13395)Victor Stinner2019-05-171-0/+1
| | | | | | | | | | | | | | | * Add _PyInitError functions: * _PyInitError_Ok() * _PyInitError_Error() * _PyInitError_NoMemory() * _PyInitError_Exit() * _PyInitError_IsError() * _PyInitError_IsExit() * _PyInitError_Failed() * frozenmain.c and _testembed.c now use functions rather than macros. * Move _Py_INIT_xxx() macros to the internal API. * Move _PyWstrList_INIT macro to the internal API.
* bpo-36763: Rework _PyInitError API (GH-13031)Victor Stinner2019-05-011-2/+2
| | | | | | | | | * Remove _PyInitError.user_err field and _Py_INIT_USER_ERR() macro: use _Py_INIT_ERR() instead. _Py_ExitInitError() now longer calls abort() on error: exit with exit code 1 instead. * Add _PyInitError._type private field. * exitcode field type is now unsigned int on Windows. * Rename prefix field to _func. * Rename msg field to err_msg.
* bpo-35550: Fix incorrect Solaris define guards (GH-11275)Jakub Kulík2018-12-311-2/+2
| | | | | | | Python source code uses on several places ifdef sun or defined(sun) without the underscores, which is not standard compliant and shouldn't be used. Defines should check for __sun instead.

* bpo-18407: win32_urandom() uses PY_DWORD_MAX (GH-10656)Victor Stinner2018-11-221-4/+2
| | | | | | CryptGenRandom() maximum size is PY_DWORD_MAX, not INT_MAX. Use DWORD type for the 'chunk' variable Co-Authored-By: Jeremy Kloth <jeremy.kloth@gmail.com>
* 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
* bpo-35214: Initial clang MemorySanitizer support (GH-10479)Gregory P. Smith2018-11-121-0/+9
| | | | | | | | | | Adds configure flags for msan and ubsan builds to make it easier to enable. These also encode the detail that address sanitizer and memory sanitizer should disable pymalloc. Define MEMORY_SANITIZER when appropriate at build time and adds workarounds to existing code to mark things as initialized where the sanitizer is otherwise unable to determine that. This lets our build succeed under the memory sanitizer. not all tests pass without sanitizer failures yet but we're in pretty good shape after this.
* bpo-34170: Add Python/coreconfig.c for _PyCoreConfig (GH-8607)Victor Stinner2018-08-011-29/+0
| | | | | | | * Add Include/coreconfig.h * Move config_*() and _PyCoreConfig_*() functions from Modules/main.c to a new Python/coreconfig.c file. * Inline _Py_ReadHashSeed() into config_init_hash_seed() * Move global configuration variables to coreconfig.c
* bpo-33021: Release the GIL during fstat() calls (GH-6019)Nir Soffer2018-03-111-1/+6
| | | | | | | | | | | | | | fstat may block for long time if the file descriptor is on a non-responsive NFS server, hanging all threads. Most fstat() calls are handled by _Py_fstat(), releasing the GIL internally, but but _Py_fstat_noraise() does not release the GIL, and most calls release the GIL explicitly around it. This patch fixes last 2 calls to _Py_fstat_no_raise(), avoiding hangs when calling: - mmap.mmap() - os.urandom() - random.seed()
* bpo-32329: Fix -R option for hash randomization (#4873)Victor Stinner2017-12-141-27/+10
| | | | | | | | | | | | bpo-32329, bpo-32030: * The -R option now turns on hash randomization when the PYTHONHASHSEED environment variable is set to 0 Previously, the option was ignored. * sys.flags.hash_randomization is now properly set to 0 when hash randomization is turned off by PYTHONHASHSEED=0. * _PyCoreConfig_ReadEnv() now reads the PYTHONHASHSEED environment variable. _Py_HashRandomization_Init() now only apply the configuration, it doesn't read PYTHONHASHSEED anymore.
* bpo-32241: Add the const qualifire to declarations of umodifiable strings. ↵Serhiy Storchaka2017-12-121-4/+4

* bpo-32030: Enhance Py_Main() (#4412)Victor Stinner2017-11-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parse more env vars in Py_Main(): * Add more options to _PyCoreConfig: * faulthandler * tracemalloc * importtime * Move code to parse environment variables from _Py_InitializeCore() to Py_Main(). This change fixes a regression from Python 3.6: PYTHONUNBUFFERED is now read before calling pymain_init_stdio(). * _PyFaulthandler_Init() and _PyTraceMalloc_Init() now take an argument to decide if the module has to be enabled at startup. * tracemalloc_start() is now responsible to check the maximum number of frames. Other changes: * Cleanup Py_Main(): * Rename some pymain_xxx() subfunctions * Add pymain_run_python() subfunction * Cleanup Py_NewInterpreter() * _PyInterpreterState_Enable() now reports failure * init_hash_secret() now considers pyurandom() failure as an "user error": don't fail with abort(). * pymain_optlist_append() and pymain_strdup() now sets err on memory allocation failure.
* bpo-32030: Split Py_Main() into subfunctions (#4399)Victor Stinner2017-11-151-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Don't use "Python runtime" anymore to parse command line options or to get environment variables: pymain_init() is now a strict separation. * Use an error message rather than "crashing" directly with Py_FatalError(). Limit the number of calls to Py_FatalError(). It prepares the code to handle errors more nicely later. * Warnings options (-W, PYTHONWARNINGS) and "XOptions" (-X) are now only added to the sys module once Python core is properly initialized. * _PyMain is now the well identified owner of some important strings like: warnings options, XOptions, and the "program name". The program name string is now properly freed at exit. pymain_free() is now responsible to free the "command" string. * Rename most methods in Modules/main.c to use a "pymain_" prefix to avoid conflits and ease debug. * Replace _Py_CommandLineDetails_INIT with memset(0) * Reorder a lot of code to fix the initialization ordering. For example, initializing standard streams now comes before parsing PYTHONWARNINGS. * Py_Main() now handles errors when adding warnings options and XOptions. * Add _PyMem_GetDefaultRawAllocator() private function. * Cleanup _PyMem_Initialize(): remove useless global constants: move them into _PyMem_Initialize(). * Call _PyRuntime_Initialize() as soon as possible: _PyRuntime_Initialize() now returns an error message on failure. * Add _PyInitError structure and following macros: * _Py_INIT_OK() * _Py_INIT_ERR(msg) * _Py_INIT_USER_ERR(msg): "user" error, don't abort() in that case * _Py_INIT_FAILED(err)
* bpo-22257: Private C-API for core runtime initialization (PEP 432). (#1772)Eric Snow2017-05-241-3/+5

* bpo-22257: Small changes for PEP 432. (#1728)Eric Snow2017-05-231-0/+629
PEP 432 specifies a number of large changes to interpreter startup code, including exposing a cleaner C-API. The major changes depend on a number of smaller changes. This patch includes all those smaller changes.
