* bpo-38304: PyConfig_InitPythonConfig() cannot fail anymore (GH-16509)Victor Stinner2019-10-011-7/+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 Stinner2019-10-011-1/+0
| | | | | | | 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 Stinner2019-09-281-0/+1
| | | | | | | | | | | | | | | | | 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-36763: Use PyConfig_Clear() (GH-14445)Victor Stinner2019-07-011-1/+1
| | | | | Stop using "static PyConfig", PyConfig must now always use dynamically allocated strings: use PyConfig_SetString(), PyConfig_SetArgv() and PyConfig_Clear().
* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 _PyPreConfig._config_init (GH-13481)Victor Stinner2019-05-221-5/+17
| | | | | | | | | | | | | | | | | | | * _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-36763: Use _PyCoreConfig_InitPythonConfig() (GH-13398)Victor Stinner2019-05-181-4/+2
| | | | | | | | | | | | | | | | | _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-36763: Add _PyInitError functions (GH-13395)Victor Stinner2019-05-171-1/+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: Add _PyCoreConfig_InitPythonConfig() (GH-13388)Victor Stinner2019-05-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Add _Py_InitializeMain() (GH-13362)Victor Stinner2019-05-161-1/+2
| | | | | | | | | * 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-36594: Fix incorrect use of %p in format strings (GH-12769)Zackery Spytz2019-05-061-1/+1
| | | In addition, fix some other minor violations of C99.

* bpo-36444: Add _PyCoreConfig._init_main (GH-12572)Victor Stinner2019-03-271-1/+2
| | | | | | | | * Add _PyCoreConfig._init_main: if equals to zero, _Py_InitializeFromConfig() doesn't call _Py_InitializeMainInterpreter(). * Add interp_p parameter to _Py_InitializeFromConfig(). * pymain_init() now calls _Py_InitializeFromConfig(). * Make _Py_InitializeCore() private.
* bpo-36301: Remove _PyCoreConfig.preconfig (GH-12546)Victor Stinner2019-03-261-1/+1
| | | | | | * Replace _PyCoreConfig.preconfig with 3 new fields in _PyCoreConfig: isolated, use_environment, dev_mode. * Add _PyPreCmdline.dev_mode. * Add _Py_PreInitializeFromPreConfigInPlace().
* bpo-36142: Add _PyPreConfig structure (GH-12172)Victor Stinner2019-03-051-1/+1
| | | | | | * Add _PyPreConfig structure * Move 'ignored' and 'use_environment' fields from _PyCoreConfig to _PyPreConfig * Add a new "_PyPreConfig preconfig;" field to _PyCoreConfig
* bpo-36142: Rework error reporting in pymain_main() (GH-12113)Victor Stinner2019-03-011-1/+1
| | | | | | | | | | | Add a new _Py_INIT_EXIT() macro to be able to exit Python with an exitcode using _PyInitError API. Rewrite function calls by pymain_main() to use _PyInitError. Changes: * Remove _PyMain.err and _PyMain.status field * Add _Py_INIT_EXIT() macro and _PyInitError.exitcode field. * Rename _Py_FatalInitError() to _Py_ExitInitError().
* bpo-25711: Rewrite zipimport in pure Python. (GH-6809)Serhiy Storchaka2018-09-181-21/+19

* bpo-34523: Support surrogatepass in locale codecs (GH-8995)Victor Stinner2018-08-291-8/+0
| | | | | | | | | | | | | | | | | | | | Add support for the "surrogatepass" error handler in PyUnicode_DecodeFSDefault() and PyUnicode_EncodeFSDefault() for the UTF-8 encoding. Changes: * _Py_DecodeUTF8Ex() and _Py_EncodeUTF8Ex() now support the surrogatepass error handler (_Py_ERROR_SURROGATEPASS). * _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx() now use the _Py_error_handler enum instead of "int surrogateescape" to pass the error handler. These functions now return -3 if the error handler is unknown. * Add unit tests on _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx() in test_codecs. * Rename get_error_handler() to _Py_GetErrorHandler() and expose it as a private function. * _freeze_importlib doesn't need config.filesystem_errors="strict" workaround anymore.
* bpo-34523: Add _PyCoreConfig.filesystem_encoding (GH-8963)Victor Stinner2018-08-291-1/+8
| | | | | | | | | | | | | | | | | | | | | | | _PyCoreConfig_Read() is now responsible to choose the filesystem encoding and error handler. Using Py_Main(), the encoding is now chosen even before calling Py_Initialize(). _PyCoreConfig.filesystem_encoding is now the reference, instead of Py_FileSystemDefaultEncoding, for the Python filesystem encoding. Changes: * Add filesystem_encoding and filesystem_errors to _PyCoreConfig * _PyCoreConfig_Read() now reads the locale encoding for the file system encoding. * PyUnicode_EncodeFSDefault() and PyUnicode_DecodeFSDefaultAndSize() now use the interpreter configuration rather than Py_FileSystemDefaultEncoding and Py_FileSystemDefaultEncodeErrors global configuration variables. * Add _Py_SetFileSystemEncoding() and _Py_ClearFileSystemEncoding() private functions to only modify Py_FileSystemDefaultEncoding and Py_FileSystemDefaultEncodeErrors in coreconfig.c. * _Py_CoerceLegacyLocale() now takes an int rather than _PyCoreConfig for the warning.
* bpo-34170: Add _PyCoreConfig._frozen parameter (GH-8591)Victor Stinner2018-08-011-2/+1
| | | Modify frozenmain.c to use _Py_InitializeFromConfig().
* bpo-34170: Cleanup pymain_read_conf() (GH-8476)Victor Stinner2018-07-261-1/+1
| | | | | | | | | | * Config: Rename ignore_environment field to use_environment. * _PyCoreConfig_Read(): if isolated is set, use_environment and site_import are now always set to 0. * Inline pymain_free_raw() into pymain_free() * Move config_init_warnoptions() call into pymain_read_conf_impl() * _PyCoreConfig_Read(): don't replace values if they are already set: faulthandler, pycache_prefix, home.
* bpo-34170: Add _Py_InitializeFromConfig() (GH-8454)Victor Stinner2018-07-251-6/+12
| | | | | | | | | | | | | | * If _Py_InitializeCore() is called twice, the second call now copies and apply (partially) the new configuration. * Rename _Py_CommandLineDetails to _PyCmdline * Move more code into pymain_init(). The core configuration created by Py_Main() is new destroyed before running Python to reduce the memory footprint. * _Py_InitializeCore() now returns the created interpreter. _Py_InitializeMainInterpreter() now expects an interpreter. * Remove _Py_InitializeEx_Private(): _freeze_importlib now uses _Py_InitializeFromConfig() * _PyCoreConfig_InitPathConfig() now only computes the path configuration if needed.
* bpo-32030: Split Py_Main() into subfunctions (#4399)Victor Stinner2017-11-151-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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)
