* bpo-44131: Py_FrozenMain() uses PyConfig_SetBytesArgv() (GH-26201)Victor Stinner2021-05-202-27/+30
| | | | | Moreover, Py_FrozenMain() relies on Py_InitializeFromConfig() to handle the PYTHONUNBUFFERED environment variable and configure C stdio streams like stdout (make the stream unbuffered).
* bpo-44131: Fix Makefile for test_frozenmain (GH-26203)Victor Stinner2021-05-182-1/+4
| | | | Remove Programs/test_frozenmain.h Makefile target: it ran make in parallel which caused build errors on LTO+PGO builds.
* bpo-44131: Test Py_FrozenMain() (GH-26126)Victor Stinner2021-05-174-9/+150
| | | | | | | | | * Add test_frozenmain to test_embed * Add Programs/test_frozenmain.py * Add Programs/freeze_test_frozenmain.py * Add Programs/test_frozenmain.h * Add make regen-test-frozenmain * Add test_frozenmain command to Programs/_testembed * _testembed.c: add error(msg) function
* bpo-44113: Deprecate old functions to config Python init (GH-26060)Victor Stinner2021-05-121-0/+5
| | | | | | | | | | | | | | | | | Deprecate the following functions to configure the Python initialization: * PySys_AddWarnOption() * PySys_AddWarnOptionUnicode() * PySys_AddXOption() * PySys_HasWarnOptions() * Py_SetPath() * Py_SetProgramName() * Py_SetPythonHome() * Py_SetStandardStreamEncoding() * _Py_SetProgramFullPath() Use the new PyConfig API of the Python Initialization Configuration instead (PEP 587).
* bpo-43445: Add frozen modules to sys.stdlib_module_names (GH-24798)Victor Stinner2021-03-101-0/+16
| | | | | | Add frozen modules to sys.stdlib_module_names. For example, add "_frozen_importlib" and "_frozen_importlib_external" names. Add "list_frozen" command to Programs/_testembed.
* bpo-42882: Add test_embed.test_unicode_id_init() (GH-24198)Victor Stinner2021-01-121-0/+38
| | | | Test that _PyUnicode_FromId() works when Python is initialized multiples times.
* bpo-42260: Compute the path config in the main init (GH-23211)Victor Stinner2020-11-101-2/+2
| | | | | | | | | | | | | | | | | | | | | The path configuration is now computed in the "main" initialization. The core initialization no longer computes it. * Add _PyConfig_Read() function to read the configuration without computing the path configuration. * pyinit_core() no longer computes the path configuration: it is now computed by init_interp_main(). * The path configuration output members of PyConfig are now optional: * executable * base_executable * prefix * base_prefix * exec_prefix * base_exec_prefix * _PySys_UpdateConfig() now skips NULL strings in PyConfig. * _testembed: Rename test_set_config() to test_init_set_config() for consistency with other tests.
* bpo-42260: Add _PyInterpreterState_SetConfig() (GH-23158)Victor Stinner2020-11-041-0/+50
| | | | | | | | * Inline _PyInterpreterState_SetConfig(): replace it with _PyConfig_Copy(). * Add _PyErr_SetFromPyStatus() * Add _PyInterpreterState_GetConfigCopy() * Add a new _PyInterpreterState_SetConfig() function. * Add an unit which gets, modifies, and sets the config.
* bpo-41162: Clear audit hooks later during finalization (GH-21222)Konge2020-07-031-0/+8

* bpo-40939: Remove some extra references to PYTHONOLDPARSER (GH-20815)Pablo Galindo2020-06-111-3/+0
| | | Automerge-Triggered-By: @pablogsal
* bpo-40939: Remove the old parser (GH-20768)Pablo Galindo2020-06-111-1/+0
| | | This commit removes the old parser, the deprecated parser module, the old parser compatibility flags and environment variables and all associated support code and documentation.
* bpo-40910: Export Py_GetArgcArgv() function (GH-20721)Victor Stinner2020-06-081-0/+42
| | | | | | | | | | | | 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-40854: Allow overriding sys.platlibdir via PYTHONPLATLIBDIR env-var ↵Sandro Mani2020-06-081-0/+8
| | | | (GH-20605)
* bpo-40453: Add PyConfig._isolated_subinterpreter (GH-19820)Victor Stinner2020-05-011-0/+2
| | | | | | | | | An isolated subinterpreter cannot spawn threads, spawn a child process or call os.fork(). * Add private _Py_NewInterpreter(isolated_subinterpreter) function. * Add isolated=True keyword-only parameter to _xxsubinterpreters.create(). * Allow again os.fork() in "non-isolated" subinterpreters.
* bpo-40334: Rename PyConfig.use_peg to _use_peg_parser (GH-19670)Victor Stinner2020-04-231-2/+3
| | | | | | | | | | | * Rename PyConfig.use_peg to _use_peg_parser * Document PyConfig._use_peg_parser and mark it a deprecated * Mark -X oldparser option and PYTHONOLDPARSER env var as deprecated in the documentation. * Add use_old_parser() and skip_if_new_parser() to test.support * Remove sys.flags.use_peg: use_old_parser() uses _testinternalcapi.get_configs() instead. * Enhance test_embed tests * subprocess._args_from_interpreter_flags() copies -X oldparser
* bpo-40334: PEP 617 implementation: New PEG parser for CPython (GH-19503)Pablo Galindo2020-04-221-0/+3

* bpo-40268: Remove unused imports in pylifecycle.c (GH-19533)Victor Stinner2020-04-151-1/+0
| | | | | | | | | | Remove unused imports in files: * initconfig.c * main.c * preconfig.h * pylifecycle.c * python.c * pythonrun.c
* bpo-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-151-1/+0
| | | | Remove explicit pythread.h includes: it is always included by Python.h.
* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-141-2/+2
|
* bpo-39877: Remove useless PyEval_InitThreads() calls (GH-18883)Victor Stinner2020-03-091-4/+2
| | | | Py_Initialize() calls PyEval_InitThreads() since Python 3.7. It's no longer needed to call it explicitly.
* bpo-39489: Remove COUNT_ALLOCS special build (GH-18259)Victor Stinner2020-02-031-1/+0
| | | | | | | | | | | Remove: * COUNT_ALLOCS macro * sys.getcounts() function * SHOW_ALLOC_COUNT code in listobject.c * SHOW_TRACK_COUNT code in tupleobject.c * PyConfig.show_alloc_count field * -X showalloccount command line option * @test.support.requires_type_collecting decorator

| | | | PyConfig_InitPythonConfig() and PyConfig_InitIsolatedConfig() no longer return PyStatus: they cannot fail anymore.
* bpo-38304: Remove PyConfig.struct_size (GH-16500) (GH-16508)Victor Stinner2019-10-012-93/+17
| | | | | | | 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-38317: Fix PyConfig.warnoptions priority (GH-16478)Victor Stinner2019-09-291-0/+59
| | | | | | | | | Fix warnings options priority: PyConfig.warnoptions has the highest priority, as stated in the PEP 587. * Document options order in PyConfig.warnoptions documentation. * Make PyWideStringList_INIT macro private: replace "Py" prefix with "_Py". * test_embed: add test_init_warnoptions().
* bpo-38304: Add PyConfig.struct_size (GH-16451)Victor Stinner2019-09-282-13/+109
| | | | | | | | | | | | | | | | | 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: Fix test_embed.test_init_setpath_config() on FreeBSD (GH-16406)Victor Stinner2019-09-261-1/+11
| | | | | | | | | Explicitly preinitializes with a Python preconfiguration to avoid Py_SetPath() implicit preinitialization with a compat preconfiguration. Fix also test_init_setpath() and test_init_setpythonhome() on macOS: use self.test_exe as the executable (and base_executable), rather than shutil.which('python3').
* bpo-38234: Add test_init_setpath_config() to test_embed (GH-16402)Victor Stinner2019-09-261-27/+25
| | | | | | | | | | | | * Add test_embed.test_init_setpath_config(): test Py_SetPath() with PyConfig. * test_init_setpath() and test_init_setpythonhome() no longer call Py_SetProgramName(), but use the default program name. * _PyPathConfig: isolated, site_import and base_executable fields are now only available on Windows. * If executable is set explicitly in the configuration, ignore calculated base_executable: _PyConfig_InitPathConfig() copies executable to base_executable. * Complete path config documentation.
* bpo-38234: Add tests for Python init path config (GH-16358)Victor Stinner2019-09-241-10/+95

* bpo-36763: PyConfig_Read() handles PySys_AddXOption() (GH-15431)Victor Stinner2019-08-231-0/+49
| | | | | | | | | | PyConfig_Read() is now responsible to handle early calls to PySys_AddXOption() and PySys_AddWarnOption(). Options added by PySys_AddXOption() are now handled the same way than PyConfig.xoptions and command line -X options. For example, PySys_AddXOption(L"faulthandler") enables faulthandler as expected.

| | | | | | | | | | | | | | | | | | | | | * 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
* bpo-36763: Use _PyCoreConfig_InitPythonConfig() (GH-13398)Victor Stinner2019-05-182-38/+79
| | | | | | | | | | | | | | | | | _PyPreConfig_InitPythonConfig() and _PyCoreConfig_InitPythonConfig() no longer inherit their values from global configuration variables. Changes: * _PyPreCmdline_Read() now ignores -X dev and PYTHONDEVMODE if dev_mode is already set. * Inline _PyPreConfig_INIT macro into _PyPreConfig_Init() function. * Inline _PyCoreConfig_INIT macro into _PyCoreConfig_Init() function. * Replace _PyCoreConfig_Init() with _PyCoreConfig_InitPythonConfig() in most tests of _testembed.c. * Replace _PyCoreConfig_Init() with _PyCoreConfig_InitIsolatedConfig() in _freeze_importlib.c. * Move some initialization functions from the internal to the private API.

* bpo-36945: Add _PyPreConfig.configure_locale (GH-13368)Victor Stinner2019-05-171-0/+28
| | | | | _PyPreConfig_InitIsolatedConfig() sets configure_locale to 0 to prevent Python to modify the LC_CTYPE locale. In that case, coerce_c_locale an coerce_c_locale_warn are set to 0 as well.
* bpo-36763: Add _PyCoreConfig_InitPythonConfig() (GH-13388)Victor Stinner2019-05-172-29/+125

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 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: Add _PyCoreConfig.parse_argv (GH-13361)Victor Stinner2019-05-161-0/+32
| | | | | | | * _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().
