* gh-107211: No longer export internal functions (6) (#108424)Victor Stinner2023-08-241-0/+1
| | | | | | | | | | | | No longer export these 5 internal C API functions: * _PyArena_AddPyObject() * _PyArena_Free() * _PyArena_Malloc() * _PyArena_New() * _Py_FatalRefcountErrorFunc() Change comment style to "// comment" and add comment explaining why other functions have to be exported.
* gh-107211: No longer export internal functions (4) (#107217)Victor Stinner2023-07-251-0/+1
| | | | | | | | | No longer export these 2 internal C API functions: * _PyEval_SignalAsyncExc() * _PyEval_SignalReceived() Add also comments explaining why some internal functions have to be exported, and update existing comments.
* bpo-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-031-54/+4
| | | | | 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-45211: Remember the stdlib dir during startup. (gh-28586)Eric Snow2021-09-281-0/+1
| | | | | During runtime startup we figure out the stdlib dir but currently throw that information away. This change preserves it and exposes it via PyConfig.stdlib_dir, _Py_GetStdlibDir(), and sys._stdlib_dir. https://bugs.python.org/issue45211
* bpo-29778: test_embed tests the path configuration (GH-21306)Victor Stinner2020-07-071-0/+1
|
* bpo-39372: Clean header files of declared interfaces with no implementations ↵Pablo Galindo2020-01-181-2/+0
| | | | | | | | (GH-18037) The public API symbols being removed are: _PyBytes_InsertThousandsGroupingLocale, _PyBytes_InsertThousandsGrouping, _Py_InitializeFromArgs, _Py_InitializeFromWideArgs, _PyFloat_Repr, _PyFloat_Digits, _PyFloat_DigitsInit, PyFrame_ExtendStack, _PyAIterWrapper_Type, PyNullImporter_Type, PyCmpWrapper_Type, PySortWrapper_Type, PyNoArgsFunction.
* bpo-38353: getpath.c: allocates strings on the heap (GH-16585)Victor Stinner2019-10-041-3/+2
| | | | | | | | | | | * _Py_FindEnvConfigValue() now returns a string allocated by PyMem_RawMalloc(). * calculate_init() now decodes VPATH macro. * Add calculate_open_pyenv() function. * Add substring() and joinpath2() functions. * Fix add_exe_suffix() And a few cleanup changes.
* bpo-38234: Py_Initialize() sets global path configuration (GH-16421)Victor Stinner2019-09-261-1/+1
| | | | | | * 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: Add test_init_setpath_config() to test_embed (GH-16402)Victor Stinner2019-09-261-4/+11
| | | | | | | | | | | | * 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-38236: Dump path config at first import error (GH-16300)Victor Stinner2019-09-231-0/+1
| | | | Python now dumps path configuration if it fails to import the Python codecs of the filesystem and stdio encodings.
* bpo-38234: Remove _PyPathConfig.dll_path (GH-16307)Victor Stinner2019-09-201-4/+6
| | | | | | | | | 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-37369: Fix initialization of sys members when launched via an app ↵Steve Dower2019-06-291-0/+2
| | | | | | | container (GH-14428) sys._base_executable is now always defined on all platforms, and can be overridden through configuration. Also adds test.support.PythonSymlink to encapsulate platform-specific logic for symlinking sys.executable
* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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: Remove _PyCoreConfig.dll_path (GH-13402)Victor Stinner2019-05-181-0/+4

* bpo-36635: Change pyport.h for Py_BUILD_CORE_MODULE define (GH-12853)Victor Stinner2019-04-171-2/+2
| | | | | | | | | | | | | | | | | | | | Change PyAPI_FUNC(type), PyAPI_DATA(type) and PyMODINIT_FUNC macros of pyport.h when Py_BUILD_CORE_MODULE is defined. The Py_BUILD_CORE_MODULE define must be now be used to build a C extension as a dynamic library accessing Python internals: export the PyInit_xxx() function in DLL exports on Windows. Changes: * Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE now imply Py_BUILD_CORE directy in pyport.h. * ceval.c compilation now fails with an error if Py_BUILD_CORE is not defined, just to ensure that Python is build with the correct defines. * setup.py now compiles _pickle.c with Py_BUILD_CORE_MODULE define. * setup.py compiles _json.c with Py_BUILD_CORE_MODULE define, rather than Py_BUILD_CORE_BUILTIN define * PCbuild/pythoncore.vcxproj: Add Py_BUILD_CORE_BUILTIN define.
* bpo-36236: Handle removed cwd at Python init (GH-12424)Victor Stinner2019-03-191-1/+3
| | | | | | | | At Python initialization, the current directory is no longer prepended to sys.path if it has been removed. Rename _PyPathConfig_ComputeArgv0() to _PyPathConfig_ComputeSysPath0() to avoid confusion between argv[0] and sys.path[0].
* bpo-36301: Add _PyWstrList structure (GH-12343)Victor Stinner2019-03-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace messy _Py_wstrlist_xxx() functions with a new clean _PyWstrList structure and new _PyWstrList_xxx() functions. Changes: * Add _PyCoreConfig.use_module_search_paths to decide if _PyCoreConfig.module_search_paths should be computed or not, to support empty search path list. * _PyWstrList_Clear() sets length to 0 and items to NULL, whereas _Py_wstrlist_clear() only freed memory. * _PyWstrList_Append() returns an int, whereas _Py_wstrlist_append() returned _PyInitError. * _PyWstrList uses Py_ssize_t for the length, instead of int. * Replace (int, wchar_t**) with _PyWstrList in: * _PyPreConfig * _PyCoreConfig * _PyPreCmdline * _PyCmdline * Replace "int orig_argv; wchar_t **orig_argv;" with "_PyWstrList orig_argv". * _PyCmdline and _PyPreCmdline now also copy wchar_argv. * Rename _PyArgv_Decode() to _PyArgv_AsWstrList(). * PySys_SetArgvEx() now pass the fixed (argc, argv) to _PyPathConfig_ComputeArgv0() (don't pass negative argc or NULL argv). * _PyOS_GetOpt() uses Py_ssize_t
* bpo-36142: Move command line parsing to coreconfig.c (GH-12123)Victor Stinner2019-03-011-14/+0
| | | | | | | | | | | | | | | * Add _PyCoreConfig_ReadFromArgv() function which parses command line options: move code from main.c to coreconfig.c. * Add _PyCoreConfig_Write() to write the new configuration: coerce the LC_CTYPE locale, set Py_xxx global configuration variables, etc. * _PyCoreConfig_ReadFromArgv() now only changes the LC_CTYPE locale temporarily. _PyCoreConfig_Write() becomes responsible to set the LC_CTYPE locale. * Add _Py_SetArgcArgv() and _Py_ClearArgcArgv() functions * Rename many "pymain_xxx()" functions * Add "const" to some function parameters * Reorganize main.c to declare functions in the order in which they are called.
* bpo-34725: Adds _Py_SetProgramFullPath so embedders may override ↵Steve Dower2018-11-181-2/+1
| | | | sys.executable (GH-9860)
* bpo-35081: Internal headers require Py_BUILD_CORE (GH-10363)Victor Stinner2018-11-091-2/+2
| | | | | | | | | * All internal header files now require Py_BUILD_CORE or Py_BUILD_CORE_BUILTIN to be defined. * _json.c is now compiled with Py_BUILD_CORE_BUILTIN to access pycore_accu.h header. * Add an example to Modules/Setup to show how to build _json as a built-in module; it requires non trivial compiler options.
* bpo-35081: Add _PyCoreConfig_AsDict() (GH-10362)Victor Stinner2018-11-061-0/+4
| | | | | | | | | | | | _testcapimodule.c must not include pycore_pathconfig.h, since it's an internal header files. Changes: * Add _PyCoreConfig_AsDict() function to coreconfig.c. * Remove pycore_pathconfig.h include from _testcapimodule.h. * pycore_pathconfig.h now requires Py_BUILD_CORE to be defined. * _testcapimodule.c compilation now fails if it's built with Py_BUILD_CORE defined.
* bpo-35081: And pycore_lifecycle.h and pycore_pathconfig.h (GH-10273)Victor Stinner2018-11-011-0/+68
* And pycore_lifecycle.h and pycore_pathconfig.h headers to Include/internal/ * Move Py_BUILD_CORE specific code from coreconfig.h and pylifecycle.h to pycore_pathconfig.h and pycore_lifecycle.h * Move _Py_wstrlist_XXX() definitions and _PyPathConfig code from pycore_state.h to pycore_pathconfig.h * Move "Init" and "Fini" function definitions from pylifecycle.c to pycore_lifecycle.h.
