* bpo-38304: PyConfig_InitPythonConfig() cannot fail anymore (GH-16509)Victor Stinner2019-10-011-10/+2
| | | | PyConfig_InitPythonConfig() and PyConfig_InitIsolatedConfig() no longer return PyStatus: they cannot fail anymore.
* bpo-38304: Remove PyConfig.struct_size (GH-16500) (GH-16508)Victor Stinner2019-10-011-8/+1
| | | | | | | For now, we'll rely on the fact that the config structures aren't covered by the stable ABI. We may revisit this in the future if we further explore the idea of offering a stable embedding API. (cherry picked from commit bdace21b769998396d0ccc8da99a8ca9b507bfdf)
* bpo-38304: Add PyConfig.struct_size (GH-16451)Victor Stinner2019-09-281-4/+25
| | | | | | | | | | | | | | | | | Add a new struct_size field to PyPreConfig and PyConfig structures to allow to modify these structures in the future without breaking the backward compatibility. * Replace private _config_version field with public struct_size field in PyPreConfig and PyConfig. * Public PyPreConfig_InitIsolatedConfig() and PyPreConfig_InitPythonConfig() return type becomes PyStatus, instead of void. * Internal _PyConfig_InitCompatConfig(), _PyPreConfig_InitCompatConfig(), _PyPreConfig_InitFromConfig(), _PyPreConfig_InitFromPreConfig() return type becomes PyStatus, instead of void. * Remove _Py_CONFIG_VERSION * Update the Initialization Configuration documentation.
* bpo-38234: Py_Initialize() sets global path configuration (GH-16421)Victor Stinner2019-09-261-2/+2
| | | | | | * Py_InitializeFromConfig() now writes PyConfig path configuration to the global path configuration (_Py_path_config). * Add test_embed.test_get_pathconfig(). * Fix typo in _PyWideStringList_Join().
* bpo-38234: Remove _PyPathConfig.dll_path (GH-16307)Victor Stinner2019-09-211-2/+2
| | | | | | | | | The DLL path is not computed from any user configuration and cannot be configured by PyConfig. Instead, add a new _Py_dll_path global variable. Remove _PyConfig_SetPathConfig(): replaced with _PyPathConfig_Init(). Py_Initialize() now longer sets the "global path configuration", but only initialize _Py_dll_path.

* bpo-38070: Add _PyRuntimeState.preinitializing (GH-16245)Victor Stinner2019-09-171-3/+8
| | | | | | Add _PyRuntimeState.preinitializing field: set to 1 while Py_PreInitialize() is running. _PyRuntimeState: rename also pre_initialized field to preinitialized.
* bpo-15999: Clean up of handling boolean arguments. (GH-15610)Serhiy Storchaka2019-09-011-2/+2
| | | | | | * Use the 'p' format unit instead of manually called PyObject_IsTrue(). * Pass boolean value instead 0/1 integers to functions that needs boolean. * Convert some arguments to boolean only once.
* Make PyXXX_Fini() functions private (GH-15531)Victor Stinner2019-08-271-12/+12
| | | | | For example, rename PyTuple_Fini() to _PyTuple_Fini(). These functions are only declared in the internal C API.

| | | Adds sys.audit, sys.addaudithook, io.open_code, and associated C APIs.
* bpo-36763: Rename private Python initialization functions (GH-13511)Victor Stinner2019-05-231-58/+50
| | | | | | | | | | | * Rename private C functions: * _Py_Initialize_ReconfigureCore => pyinit_core_reconfigure * _Py_InitializeCore_impl => pyinit_core_config * _Py_InitializeCore = > pyinit_core * _Py_InitializeMainInterpreter => pyinit_main * init_python => pyinit_python * Rename _testembed.c commands: add "test_" prefix.
* bpo-36763: Add _PyPreConfig._config_init (GH-13481)Victor Stinner2019-05-221-2/+2
| | | | | | | | | | | | | | | | | | | * _PyPreConfig_GetGlobalConfig() and _PyCoreConfig_GetGlobalConfig() now do nothing if the configuration was not initialized with _PyPreConfig_InitCompatConfig() and _PyCoreConfig_InitCompatConfig() * Remove utf8_mode=-2 special case: use utf8_mode=-1 instead. * Fix _PyPreConfig_InitPythonConfig(): * isolated = 0 instead of -1 * use_environment = 1 instead of -1 * Rename _PyConfig_INIT to _PyConfig_INIT_COMPAT * Rename _PyPreConfig_Init() to _PyPreConfig_InitCompatConfig() * Rename _PyCoreConfig_Init() to _PyCoreConfig_InitCompatConfig() * PyInterpreterState_New() now uses _PyCoreConfig_InitPythonConfig() as default configuration, but it's very quickly overriden anyway. * _freeze_importlib.c uses _PyCoreConfig_SetString() to set program_name. * Cleanup preconfig_init_utf8_mode(): cmdline is always non-NULL.
* bpo-36829: Add sys.unraisablehook() (GH-13187)Victor Stinner2019-05-221-0/+12
| | | | | | | | | | | | | | | | | | | Add new sys.unraisablehook() function which can be overridden to control how "unraisable exceptions" are handled. It is called when an exception has occurred but there is no way for Python to handle it. For example, when a destructor raises an exception or during garbage collection (gc.collect()). Changes: * Add an internal UnraisableHookArgs type used to pass arguments to sys.unraisablehook. * Add _PyErr_WriteUnraisableDefaultHook(). * The default hook now ignores exception on writing the traceback. * test_sys now uses unittest.main() to automatically discover tests: remove test_main(). * Add _PyErr_Init(). * Fix PyErr_WriteUnraisable(): hold a strong reference to sys.stderr while using it
* bpo-36763: Fix _PyRuntime.preconfig.coerce_c_locale (GH-13444)Victor Stinner2019-05-201-7/+19
| | | | | | | | | | | _PyRuntime.preconfig.coerce_c_locale can now be used to check if the C locale has been coerced. * Fix _Py_LegacyLocaleDetected(): don't attempt to coerce the C locale if LC_ALL environment variable is set. Add 'warn' parameter: emit_stderr_warning_for_legacy_locale() must not the LC_ALL env var. * _PyPreConfig_Write() sets coerce_c_locale to 0 if _Py_CoerceLegacyLocale() fails.
* bpo-36763: Fix Python preinitialization (GH-13432)Victor Stinner2019-05-201-20/+37
| | | | | | | | | | | | | | | | | | | | | * Add _PyPreConfig.parse_argv * Add _PyCoreConfig._config_init field and _PyCoreConfigInitEnum enum type * Initialization functions: reject preconfig=NULL and config=NULL * Add config parameter to _PyCoreConfig_DecodeLocaleErr(): pass config->argv to _Py_PreInitializeFromPyArgv(), to parse config command line arguments in preinitialization. * Add config parameter to _PyCoreConfig_SetString(). It now preinitializes Python. * _PyCoreConfig_SetPyArgv() now also preinitializes Python for wide argv * Fix _Py_PreInitializeFromCoreConfig(): don't pass args to _Py_PreInitializeFromPyArgv() if config.parse_argv=0. * Use "char * const *" and "wchar_t * const *" types for 'argv' parameters and _PyArgv.argv. * Add unit test on preinitialization from argv. * _PyPreConfig.allocator type becomes int * Add _PyPreConfig_InitFromPreConfig() and _PyPreConfig_InitFromCoreConfig() helper functions

| | | | | | | * The type of initlization function 'argc' parameters becomes Py_ssize_t, instead of int. * Change _PyPreConfig_Copy() return type to void, instead of int. The function cannot fail anymore. * Fix compilation warnings on Windows.
* bpo-36763: Add _PyCoreConfig_InitPythonConfig() (GH-13388)Victor Stinner2019-05-171-8/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new functions to get the Python interpreter behavior: * _PyPreConfig_InitPythonConfig() * _PyCoreConfig_InitPythonConfig() Add new functions to get an isolated configuration: * _PyPreConfig_InitIsolatedConfig() * _PyCoreConfig_InitIsolatedConfig() Replace _PyPreConfig_INIT and _PyCoreConfig_INIT with new functions _PyPreConfig_Init() and _PyCoreConfig_Init(). _PyCoreConfig: set configure_c_stdio and parse_argv to 0 by default to behave as Python 3.6 in the default configuration. _PyCoreConfig_Read() no longer sets coerce_c_locale_warn to 1 if it's equal to 0. coerce_c_locale_warn must now be set to -1 (ex: using _PyCoreConfig_InitPythonConfig()) to enable C locale coercion warning. Add unit tests for _PyCoreConfig_InitPythonConfig() and _PyCoreConfig_InitIsolatedConfig(). Changes: * Rename _PyCoreConfig_GetCoreConfig() to _PyPreConfig_GetCoreConfig() * Fix core_read_precmdline(): handle parse_argv=0 * Fix _Py_PreInitializeFromCoreConfig(): pass coreconfig.argv to _Py_PreInitializeFromPyArgv(), except if parse_argv=0

| | | | | | | | | | | | | | * Add PyMemAllocatorName enum * _PyPreConfig.allocator type becomes PyMemAllocatorName, instead of char* * Remove _PyPreConfig_Clear() * Add _PyMem_GetAllocatorName() * Rename _PyMem_GetAllocatorsName() to _PyMem_GetCurrentAllocatorName() * Remove _PyPreConfig_SetAllocator(): just call _PyMem_SetupAllocators() directly, we don't have do reallocate the configuration with the new allocator anymore! * _PyPreConfig_Write() parameter becomes const, as it should be in the first place!
* bpo-36763: Add _Py_InitializeMain() (GH-13362)Victor Stinner2019-05-161-1/+16
| | | | | | | | | * Add a private _Py_InitializeMain() function. * Add again _PyCoreConfig._init_main. * _Py_InitializeFromConfig() now uses _init_main to decide if _Py_InitializeMainInterpreter() should be called. * _PyCoreConfig: rename _frozen to pathconfig_warnings, its value is now the opposite of Py_FrozenFlag. * Add an unit test for _init_main=0 and _Py_InitializeMain().
* bpo-36763: _PyInitError always use int for exitcode (GH-13360)Victor Stinner2019-05-161-7/+4
| | | | | | | | | | | | | | | | | We cannot use "unsigned int" for exitcode on Windows, since Py_Main() and _Py_RunMain() always return an "int". Changes: * _PyPathConfig_ComputeSysPath0() now returns -1 if an exception is raised. * pymain_run_python() no longer uses _PyInitError but display the exception and set exitcode to 1 in case of error. * Fix _Py_RunMain(): return an exitcode rather than calling exit() on pymain_run_python() failure. * _Py_ExitInitError() no longer uses ExitProcess() on Windows, use exit() on all platforms. * _Py_ExitInitError() now fails with a fatal error if 'err' is not an error not an exit.
* bpo-36900: Replace global conf vars with config (GH-13299)Victor Stinner2019-05-141-2/+3
| | | | | | Replace global configuration variables with core_config read from the current interpreter. Cleanup dynload_hpux.c.

* bpo-36710: Add 'ceval' local variable to ceval.c (GH-12934)Victor Stinner2019-05-101-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Add "struct _ceval_runtime_state *ceval = &_PyRuntime.ceval;" local variables to function to better highlight the dependency on the global variable _PyRuntime and to point directly to _PyRuntime.ceval field rather than on the larger _PyRuntime. Changes: * Add _PyRuntimeState_GetThreadState(runtime) macro. * Add _PyEval_AddPendingCall(ceval, ...) and _PyThreadState_Swap(gilstate, ...) functions. * _PyThreadState_GET() macro now calls _PyRuntimeState_GetThreadState() using &_PyRuntime. * Add 'ceval' parameter to COMPUTE_EVAL_BREAKER(), SIGNAL_PENDING_SIGNALS(), _PyEval_SignalAsyncExc(), _PyEval_SignalReceived() and _PyEval_FiniThreads() macros and functions. * Add 'tstate' parameter to call_function(), do_call_core() and do_raise(). * Add 'runtime' parameter to _Py_CURRENTLY_FINALIZING(), _Py_FinishPendingCalls() and _PyThreadState_DeleteExcept() macros and functions. * Declare 'runtime', 'tstate', 'ceval' and 'eval_breaker' variables as constant.
