* gh-105716: Support Background Threads in Subinterpreters Consistently ↵Eric Snow2023-10-021-0/+4
| | | | | | | (gh-109921) The existence of background threads running on a subinterpreter was preventing interpreters from getting properly destroyed, as well as impacting the ability to run the interpreter again. It also affected how we wait for non-daemon threads to finish. We add PyInterpreterState.threads.main, with some internal C-API functions.
* gh-109853: Fix sys.path[0] For Subinterpreters (gh-109994)Eric Snow2023-10-021-10/+28
| | | This change makes sure sys.path[0] is set properly for subinterpreters. Before, it wasn't getting set at all. This PR does not address the broader concerns from gh-109853.

* gh-106320: Remove private pythonrun API (#108599)Victor Stinner2023-08-291-0/+1
| | | | | | | | | | | Remove these private functions from the public C API: * _PyRun_AnyFileObject() * _PyRun_InteractiveLoopObject() * _PyRun_SimpleFileObject() * _Py_SourceAsString() Move them to the internal C API: add a new pycore_pythonrun.h header file. No longer export these functions.
* gh-105145: Remove old functions to config Python init (#105154)Victor Stinner2023-06-011-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the following old functions to configure the Python initialization, deprecated in Python 3.11: * PySys_AddWarnOptionUnicode() * PySys_AddWarnOption() * PySys_AddXOption() * PySys_HasWarnOptions() * PySys_SetArgvEx() * PySys_SetArgv() * PySys_SetPath() * Py_SetPath() * Py_SetProgramName() * Py_SetPythonHome() * Py_SetStandardStreamEncoding() * _Py_SetProgramFullPath() Most of these functions are kept in the stable ABI, except: * Py_SetStandardStreamEncoding() * _Py_SetProgramFullPath() Update Doc/extending/embedding.rst and Doc/extending/extending.rst to use the new PyConfig API. _testembed.c: * check_stdio_details() now sets stdio_encoding and stdio_errors of PyConfig. * Add definitions of functions removed from the API but kept in the stable ABI. * test_init_from_config() and test_init_read_set() now use PyConfig_SetString() instead of PyConfig_SetBytesString(). Remove _Py_ClearStandardStreamEncoding() internal function.

* gh-77782: Deprecate global configuration variable (#93943)Victor Stinner2022-06-171-6/+15
| | | | | | | Deprecate global configuration variable like Py_IgnoreEnvironmentFlag: the Py_InitializeFromConfig() API should be instead. Fix declaration of Py_GETENV(): use PyAPI_FUNC(), not PyAPI_DATA().
* gh-57684: Add -P cmdline option and PYTHONSAFEPATH env var (#31542)Victor Stinner2022-05-051-1/+1
| | | | | | | | | | | | Add the -P command line option and the PYTHONSAFEPATH environment variable to not prepend a potentially unsafe path to sys.path. * Add sys.flags.safe_path flag. * Add PyConfig.safe_path member. * Programs/_bootstrap_python.c uses config.safe_path=0. * Update subprocess._optim_args_from_interpreter_flags() to handle the -P command line option. * Modules/getpath.py sets safe_path to 1 if a "._pth" file is present.
* gh-92345: Import rlcompleter before sys.path is extended (#92346)Christian Heimes2022-05-051-1/+10
| | | | | | | | | | ``pymain_run_python()`` now imports ``readline`` and ``rlcompleter`` before sys.path is extended to include the current working directory of an interactive interpreter. Non-interactive interpreters are not affected. Also move imports of ``re`` and ``keyword`` module to top level so they are materialized early, too. The ``keyword`` module is trivial and the ``re`` is already imported via ``inspect`` -> ``linecache``.
* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
* bpo-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-031-1/+6
| | | | | The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code. This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.
* bpo-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)Victor Stinner2021-10-121-0/+1
| | | | | | | * Move _PyObject_CallNoArgs() to pycore_call.h (internal C API). * _ssl, _sqlite and _testcapi extensions now call the public PyObject_CallNoArgs() function, rather than _PyObject_CallNoArgs(). * _lsprof extension is now built with Py_BUILD_CORE_MODULE macro defined to get access to internal _PyObject_CallNoArgs().
* bpo-45439: Rename _PyObject_CallNoArg() to _PyObject_CallNoArgs() (GH-28891)Victor Stinner2021-10-111-1/+1
| | | | | Fix typo in the private _PyObject_CallNoArg() function name: rename it to _PyObject_CallNoArgs() to be consistent with the public function PyObject_CallNoArgs().

* bpo-32381: pymain_run_command() uses PyCF_IGNORE_COOKIE (GH-23724)Victor Stinner2020-12-231-19/+23
| | | | | | | | | | The coding cookie (ex: "# coding: latin1") is now ignored in the command passed to the -c command line option. Since pymain_run_command() uses UTF-8, pass PyCF_IGNORE_COOKIE compiler flag to the parser. pymain_run_python() no longer propages compiler flags between function calls.
* bpo-32381: pymain_run_file() uses PySys_FormatStderr() (GH-23778)Victor Stinner2020-12-151-17/+34
| | | | | If config->run_filename doesn't exist, log the error into sys.stderr using "%R" format, to escape properly unencodable characters (usually with backslashreplace).
* bpo-32381: Add _PyRun_AnyFileObject() (GH-23723)Victor Stinner2020-12-091-27/+8
| | | | | | | | | | pymain_run_file() no longer encodes the filename: pass the filename as an object to the new _PyRun_AnyFileObject() function. Add new private functions: * _PyRun_AnyFileObject() * _PyRun_InteractiveLoopObject() * _Py_FdIsInteractive()
* bpo-32381: Add _PyRun_SimpleFileObject() (GH-23709)Victor Stinner2020-12-081-27/+14
| | | | pymain_run_startup() now pass the filename as a Python object to _PyRun_SimpleFileObject().

* bpo-40268: Rename _PyInterpreterState_GET_UNSAFE() (GH-19509)Victor Stinner2020-04-141-1/+1
| | | | | | | Rename _PyInterpreterState_GET_UNSAFE() to _PyInterpreterState_GET() for consistency with _PyThreadState_GET() and to have a shorter name (help to fit into 80 columns). Add also "assert(tstate != NULL);" to the function.
* bpo-40268: Include explicitly pycore_interp.h (GH-19505)Victor Stinner2020-04-141-0/+1
| | | | pycore_pystate.h no longer includes pycore_interp.h: it's now included explicitly in files accessing PyInterpreterState.
* bpo-40268: Add _PyInterpreterState_GetConfig() (GH-19492)Victor Stinner2020-04-131-2/+2
| | | | | | | | Don't access PyInterpreterState.config member directly anymore, but use new functions: * _PyInterpreterState_GetConfig() * _PyInterpreterState_SetConfig() * _Py_GetConfig()
* bpo-38353: Cleanup includes in the internal C API (GH-16548)Victor Stinner2019-10-021-0/+1
| | | | Use forward declaration of types to avoid includes in the internal C API. Add also comment to justify other includes.
* bpo-37474: Don't call fedisableexcept() on FreeBSD (GH-16515)Victor Stinner2019-10-011-13/+0
| | | | | On FreeBSD, Python no longer calls fedisableexcept() at startup to control the floating point control mode. The call became useless since FreeBSD 6: it became the default mode.
* bpo-38304: PyConfig_InitPythonConfig() cannot fail anymore (GH-16509)Victor Stinner2019-10-011-5/+1
| | | | PyConfig_InitPythonConfig() and PyConfig_InitIsolatedConfig() no longer return PyStatus: they cannot fail anymore.
* bpo-38304: Remove PyConfig.struct_size (GH-16500) (GH-16508)Victor Stinner2019-10-011-7/+2
| | | | | | | 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 Stinner2019-09-281-1/+8
| | | | | | | | | | | | | | | | | 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-15999: Clean up of handling boolean arguments. (GH-15610)Serhiy Storchaka2019-09-011-1/+1
| | | | | | * 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.

* bpo-36763: Use PyConfig_Clear() (GH-14445)Victor Stinner2019-07-011-4/+8
| | | | | Stop using "static PyConfig", PyConfig must now always use dynamically allocated strings: use PyConfig_SetString(), PyConfig_SetArgv() and PyConfig_Clear().
* bpo-37253: Add _PyCompilerFlags_INIT macro (GH-14018)Victor Stinner2019-06-131-1/+1
| | | | | Add a new _PyCompilerFlags_INIT macro to initialize PyCompilerFlags variables, rather than initializing cf_flags and cf_feature_version explicitly in each variable.
* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-45/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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-36965: Fix includes in main.c on Windows with non-MSC compilers (GH-13421)Erik Janssens2019-05-211-2/+2
| | | | Include windows.h rather than crtdbg.h to get STATUS_CONTROL_C_EXIT constant. Moreover, include windows.h on Windows, not only when MSC is used.
* bpo-36763: _Py_RunMain() doesn't call Py_Exit() anymore (GH-13390)Victor Stinner2019-05-171-46/+75
| | | | | | | | | Py_Main() and _Py_RunMain() now return the exitcode rather than calling Py_Exit(exitcode) when calling PyErr_Print() if the current exception type is SystemExit. * Add _Py_HandleSystemExit(). * Add pymain_exit_err_print(). * Add pymain_exit_print().
* bpo-36763: Add _PyCoreConfig_InitPythonConfig() (GH-13388)Victor Stinner2019-05-171-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* bpo-36763: Remove _PyCoreConfig.program (GH-13373)Victor Stinner2019-05-171-2/+2
| | | Use _PyCoreConfig.program_name instead.
* bpo-36763: Add _PyCoreConfig.parse_argv (GH-13361)Victor Stinner2019-05-161-1/+1
| | | | | | | * _PyCoreConfig_Read() doesn't parse nor update argv if parse_argv is 0. * Move path configuration fields in _PyCoreConfig. * Add an unit test for parse_argv=0. * Remove unused "done": label in _Py_RunMain().
