* bpo-37369: Fix initialization of sys members when launched via an app ↵Steve Dower2019-06-291-3/+17
| | | | | | | 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 Stinner2019-05-271-73/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 _PyInitError functions (GH-13395)Victor Stinner2019-05-171-0/+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-34977: Use venv redirector instead of original python.exe on Windows ↵Steve Dower2018-12-101-1/+7

* Revert "bpo-34977: Add Windows App Store package (GH-10245)" (GH-11019)Victor Stinner2018-12-071-7/+1
| | | This reverts commit 468a15aaf9206448a744fc5eab3fc21f51966aad.
* bpo-35436: Add missing PyErr_NoMemory() calls and other minor bug fixes. ↵Zackery Spytz2018-12-071-2/+10
| | | | | | (GH-11015) Set MemoryError when appropriate, add missing failure checks, and fix some potential leaks.

| | | | sys.executable (GH-9860)
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-121-1/+1
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
* bpo-34217: Use lowercase header for Windows (GH-8453)erikjanss2018-07-251-1/+1

* bpo-34170: Add _PyCoreConfig.isolated (GH-8417)Victor Stinner2018-07-241-2/+2
| | | | | | | | | | | | | | | * _PyCoreConfig: add isolated and site_import attributes * Replace Py_IgnoreEnvironment with config->ignore_environment when reading the current configuration * _PyCoreConfig_Read() now sets ignore_environment, utf8_mode, isolated and site_import from Py_IgnoreEnvironment, Py_UTF8Mode, Py_IsolatedFlag and Py_NoSiteFlag * _Py_InitializeCore() now sets Py_xxx flags from the configuration * pymain_read_conf() now uses _PyCoreConfig_Copy() to save/restore the configuration. * Rename _disable_importlib of _PyCoreConfig to _install_importlib * _PyCoreConfig_SetGlobalConfig() now also set Py_HashRandomizationFlag * Replace !Py_NoSiteFlag with core_config->site_import
* bpo-34170: _PyCoreConfig_Read() leaves Py_IsolatedFlag unchanged (GH-8361)Victor Stinner2018-07-211-11/+7
| | | | | | | | | | * _PyCoreConfig_Read() no longer directly modifies Py_IsolatedFlag and Py_NoSiteFlag global configuration flags. The function now requires two pointers to integer, so these flags can be set later, to avoid side effets in _PyCoreConfig_Read(). * pathconfig_global_init() now leaves Py_IsolatedFlag and Py_NoSiteFlag unchanged. * Fix pathconfig_global_init(): avoid computing the path configuration twice, use _PyCoreConfig_SetPathConfig().
* bpo-34170: Rework _PyCoreConfig_Read() to avoid side effect (GH-8353)Victor Stinner2018-07-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Rework _PyCoreConfig_Read() function which *reads* core configuration to not *modify* the path configuration. A new _PyCoreConfig_SetPathConfig() function now recreates the path configuration from the core configuration. This function is now called very late in _Py_InitializeCore(), just before calling initimport(). Changes: * Add _PyCoreConfig.dll_path * Py_SetPath() now fails with a fatal python error on memory allocation failure. * Rename _PyPathConfig_Calculate() to _PyPathConfig_Calculate_impl() * Replace _PyPathConfig_Init() with _PyPathConfig_Calculate(): the function now requires a _PyPathConfig * Add _PyPathConfig_SetGlobal() to set the _Py_path_config global variable. * Add _PyCoreConfig_InitPathConfig(): compute the path configuration * Add _PyCoreConfig_SetPathConfig(): set path configuration from core configuration * Rename wstrlist_append() to _Py_wstrlist_append() * _Py_wstrlist_append() now handles integer overflow.
* bpo-32457: Improves handling of denormalized executable path when launching ↵Steve Dower2018-02-221-54/+42
| | | | Python (GH-5756)
* bpo-32030: Add _PyCoreConfig.module_search_paths (#4954)Victor Stinner2018-01-241-0/+3
| | | | | | | | | | | _PyCoreConfig_Read() is now responsible to compute sys.path. So sys.path is now computed before calling _Py_InitializeCore(). Changes: * Add module_search_path, module_search_paths, executable, prefix, base_prefix, exec_prefix and base_exec_prefix to _PyCoreConfig. * _PyMainInterpreterConfig_Read() now only converts wchar_t** lists into a Python list, it doesn't compute sys.path anymore.
* bpo-32030: Add _Py_FindEnvConfigValue() (#4963)Victor Stinner2017-12-211-53/+3
| | | | | | | | | | | | | | | Add a new _Py_FindEnvConfigValue() function: code shared between Windows and Unix implementations of _PyPathConfig_Calculate() to read the pyenv.cfg file. _Py_FindEnvConfigValue() now uses _Py_DecodeUTF8_surrogateescape() instead of using a Python Unicode string, the Python API must not be used early during Python initialization. Same change in Unix search_for_exec_prefix(): use _Py_DecodeUTF8_surrogateescape(). Cleanup also encode_current_locale(): PyMem_RawFree/PyMem_Free can be called with NULL. Fix also "NUL byte" => "NULL byte" typo.
* bpo-32030: Rewrite _PyMainInterpreterConfig (#4854)Victor Stinner2017-12-141-23/+22
| | | | | | | | | | | | | | | | | | | | _PyMainInterpreterConfig now contains Python objects, whereas _PyCoreConfig contains wchar_t* strings. Core config: * Rename _PyMainInterpreterConfig_ReadEnv() to _PyCoreConfig_ReadEnv() * Move 3 strings from _PyMainInterpreterConfig to _PyCoreConfig: module_search_path_env, home, program_name. * Add _PyCoreConfig_Clear() * _PyPathConfig_Calculate() now takes core config rather than main config * _PyMainInterpreterConfig_Read() now requires also a core config Main config: * Add _PyMainInterpreterConfig.module_search_path: sys.path list * Add _PyMainInterpreterConfig.argv: sys.argv list * _PyMainInterpreterConfig_Read() now computes module_search_path

* bpo-32030: _PyPathConfig_Init() sets home and program_name (#4673)Victor Stinner2017-12-021-18/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | _PyPathConfig_Init() now also initialize home and program_name: * Rename existing _PyPathConfig_Init() to _PyPathConfig_Calculate(). Add a new _PyPathConfig_Init() function in pathconfig.c which handles the _Py_path_config variable and call _PyPathConfig_Calculate(). * Add home and program_name fields to _PyPathConfig.home * _PyPathConfig_Init() now initialize home and program_name from main_config * Py_SetProgramName(), Py_SetPythonHome() and Py_GetPythonHome() now calls Py_FatalError() on failure, instead of silently ignoring failures. * config_init_home() now gets directly _Py_path_config.home to only get the value set by Py_SetPythonHome(), or NULL if Py_SetPythonHome() was not called. * config_get_program_name() now gets directly _Py_path_config.program_name to only get the value set by Py_SetProgramName(), or NULL if Py_SetProgramName() was not called. * pymain_init_python() doesn't call Py_SetProgramName() anymore, _PyPathConfig_Init() now always sets the program name * Call _PyMainInterpreterConfig_Read() in pymain_parse_cmdline_envvars_impl() to control the memory allocator * C API documentation: it's no more safe to call Py_GetProgramName() before Py_Initialize().
* bpo-32030: Add Python/pathconfig.c (#4668)Victor Stinner2017-12-011-118/+1
| | | | | | | * Factorize code from PC/getpathp.c and Modules/getpath.c to remove duplicated code * rename pathconfig_clear() to _PyPathConfig_Clear() * Inline _PyPathConfig_Fini() in pymain_impl() and then remove it, since it's a oneliner
* bpo-32030: Don't call _PyPathConfig_Fini() in Py_FinalizeEx() (#4667)Victor Stinner2017-12-011-6/+13
| | | | | | | | | | | | | | | Changes: * _PyPathConfig_Fini() cannot be called in Py_FinalizeEx(). Py_Initialize() and Py_Finalize() can be called multiple times, but it must not "forget" parameters set by Py_SetProgramName(), Py_SetPath() or Py_SetPythonHome(), whereas _PyPathConfig_Fini() clear all these parameters. * config_get_program_name() and calculate_program_full_path() now also decode paths using Py_DecodeLocale() to use the surrogateescape error handler, rather than decoding using mbstowcs() which is strict. * Change _Py_CheckPython3() prototype: () => (void) * Truncate a few lines which were too long
* bpo-32030: Fix Py_GetPath(): init program_name (#4665)Victor Stinner2017-12-011-27/+38
| | | | | | | | | | | | | | | * _PyMainInterpreterConfig_ReadEnv() now sets program_name from environment variables and pymain_parse_envvars() implements the falls back on argv[0]. * Remove _PyMain.program_name: use the program_name from _PyMainInterpreterConfig * Move the Py_SetProgramName() call back to pymain_init_python(), just before _Py_InitializeCore(). * pathconfig_global_init() now also calls _PyMainInterpreterConfig_Read() to set program_name if it isn't set yet * Cleanup PyCalculatePath: pass main_config to subfunctions to get directly fields from main_config (home, module_search_path_env and program_name)
* bpo-32030: Cleanup "path config" code (#4663)Victor Stinner2017-12-011-61/+54
| | | | | | | | | | * Rename PyPathConfig structure to _PyPathConfig and move it to Include/internal/pystate.h * Rename path_config to _Py_path_config * _PyPathConfig: Rename program_name field to program_full_path * Add assert(str != NULL); to _PyMem_RawWcsdup(), _PyMem_RawStrdup() and _PyMem_Strdup(). * Rename calculate_path() to pathconfig_global_init(). The function now does nothing if it's already initiallized.
* bpo-32030: Add _PyPathConfig_Init() (#4551)Victor Stinner2017-11-251-113/+205
| | | | | | | | | | | | | | * Add _PyPathConfig_Init() and _PyPathConfig_Fini() * Remove _Py_GetPathWithConfig() * _PyPathConfig_Init() returns _PyInitError to allow to handle errors properly * Add pathconfig_clear() * Windows calculate_path_impl(): replace Py_FatalError() with _PyInitError * Py_FinalizeEx() now calls _PyPathConfig_Fini() to release memory * Fix _Py_InitializeMainInterpreter() regression: don't initialize path config if _disable_importlib is false * PyPathConfig now uses dynamically allocated memory
* bpo-32030: Add _PyMainInterpreterConfig.program_name (#4548)Victor Stinner2017-11-241-33/+28
| | | | | | * Py_Main() now calls Py_SetProgramName() earlier to be able to get the program name in _PyMainInterpreterConfig_ReadEnv(). * Rename prog to program_name * Rename progpath to program_name
* bpo-32030: Add _PyMainInterpreterConfig_ReadEnv() (#4542)Victor Stinner2017-11-241-23/+26
| | | | | | | | | | | | | | | | | | Py_GetPath() and Py_Main() now call _PyMainInterpreterConfig_ReadEnv() to share the same code to get environment variables. Changes: * Add _PyMainInterpreterConfig_ReadEnv() * Add _PyMainInterpreterConfig_Clear() * Add _PyMem_RawWcsdup() * _PyMainInterpreterConfig: rename pythonhome to home * Rename _Py_ReadMainInterpreterConfig() to _PyMainInterpreterConfig_Read() * Use _Py_INIT_USER_ERR(), instead of _Py_INIT_ERR(), for decoding errors: the user is able to fix the issue, it's not a bug in Python. Same change was made in _Py_INIT_NO_MEMORY(). * Remove _Py_GetPythonHomeWithConfig()
* bpo-32030: Rewrite calculate_path() (#4521)Victor Stinner2017-11-231-208/+385
