PyConfig_InitPythonConfig() and PyConfig_InitIsolatedConfig() no
longer return PyStatus: they cannot fail anymore.
(cherry picked from commit 8462a4936b)
Co-authored-by: Victor Stinner <vstinner@redhat.com>
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.
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().

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.
(cherry picked from commit 441b10cf28)
* bpo-38234: Py_SetPath() uses the program full path (GH-16357)
Py_SetPath() now sets sys.executable to the program full path
(Py_GetProgramFullPath()), rather than to the program name
(Py_GetProgramName()).
Fix also memory leaks in pathconfig_set_from_config().
(cherry picked from commit 1ce152a42e)
* bpo-38234: Add tests for Python init path config (GH-16358)
(cherry picked from commit bb6bf7d342)
* bpo-38234: test_embed: test pyvenv.cfg and pybuilddir.txt (GH-16366)
Add test_init_pybuilddir() and test_init_pyvenv_cfg() to test_embed
to test pyvenv.cfg and pybuilddir.txt configuration files.
Fix sysconfig._generate_posix_vars(): pybuilddir.txt uses UTF-8
encoding, not ASCII.
(cherry picked from commit 52ad33abbf)
* bpo-38234: Cleanup getpath.c (GH-16367)
* search_for_prefix() directly calls reduce() if found is greater
than 0.
* Add calculate_pybuilddir() subfunction.
* search_for_prefix(): add path string buffer for readability.
* Fix some error handling code paths: release resources on error.
* calculate_read_pyenv(): rename tmpbuffer to filename.
* test.pythoninfo now also logs windows.dll_path
(cherry picked from commit 221fd84703)
* bpo-38234: Fix test_embed pathconfig tests (GH-16390)
bpo-38234: On macOS and FreeBSD, the temporary directory can be
symbolic link. For example, /tmp can be a symbolic link to /var/tmp.
Call realpath() to resolve all symbolic links.
(cherry picked from commit 00508a7407)
* bpo-38234: Add test_init_setpath_config() to test_embed (GH-16402)
* 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.
(cherry picked from commit 8bf39b606e)
* bpo-38234: Complete init config documentation (GH-16404)
(cherry picked from commit 88feaecd46)
* bpo-38234: Fix test_embed.test_init_setpath_config() on FreeBSD (GH-16406)
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').
(cherry picked from commit 49d99f01e6)
* bpo-38234: Py_Initialize() sets global path configuration (GH-16421)
* 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().
(cherry picked from commit 12f2f177fc)
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.
(cherry picked from commit 120b707a6d)
Stop using "static PyConfig", PyConfig must now always use
dynamically allocated strings: use PyConfig_SetString(),
PyConfig_SetArgv() and PyConfig_Clear().
(cherry picked from commit 67310023f2)

* Change Py_UTF8Mode default value to 0.
* Fix _PyPreConfig_Copy(): copy also _config_init attrbibute.
* _PyPreConfig_AsDict() exports _config_init
* Fix _PyPreConfig_GetGlobalConfig(): use Py_UTF8Mode if it's greater
than 0, even if utf8_mode >= 0.
* Add unit tests on environment variables using Python API.
* _PyPreConfig_GetGlobalConfig() and _PyCoreConfig_GetGlobalConfig()
now do nothing if the configuration was not initialized with
_PyPreConfig_InitCompatConfig() and _PyCoreConfig_InitCompatConfig()

* 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.

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.

* 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.
* Add _PyInitError functions:
* _PyInitError_Ok()
* _PyInitError_Error()
* _PyInitError_NoMemory()
* _PyInitError_Exit()
* _PyInitError_IsError()
* _PyInitError_IsExit()

* Move _Py_INIT_xxx() macros to the internal API.
* Move _PyWstrList_INIT macro to the internal API.
_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.
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!
