* bpo-39401: Avoid unsafe DLL load on Windows 7 and earlier (GH-18231)Steve Dower2020-01-291-50/+5
| | | | As Windows 7 is not supported by Python 3.9, we just replace the dynamic load with a static import. Backports will have a different fix to ensure they continue to behave the same.
* bpo-38353: getpath.c: allocates strings on the heap (GH-16585)Victor Stinner2019-10-041-6/+16
| | | | | | | | | | | * _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-38353: Cleanup includes in the internal C API (GH-16548)Victor Stinner2019-10-021-1/+2
| | | | Use forward declaration of types to avoid includes in the internal C API. Add also comment to justify other includes.
* bpo-38322: Fix gotlandmark() of PC/getpathp.c (GH-16489)Victor Stinner2019-09-301-8/+6
| | | | | | Write the filename into a temporary buffer instead of reusing prefix. The problem is that join() modifies prefix inplace. If prefix is not normalized, join() can make prefix shorter and so gotlandmark() does modify prefix instead of returning it unmodified.
* bpo-38234: Add test_init_setpath_config() to test_embed (GH-16402)Victor Stinner2019-09-261-3/+3
| | | | | | | | | | | | * 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: Cleanup getpath.c (GH-16367)Victor Stinner2019-09-251-15/+15
| | | | | | | | | * 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
* bpo-38234: read_pth_file() now returns PyStatus (GH-16338)Victor Stinner2019-09-231-76/+131
| | | | | | | | | Refactor path configuration code: * read_pth_file() now returns PyStatus to report errors, rather than calling Py_FatalError(). * Move argv0_path and zip_path buffers out of PyCalculatePath structures. * On Windows, _PyPathConfig.home is now preferred over PyConfig.home.
* bpo-38234: Fix _PyConfig_InitPathConfig() (GH-16335)Victor Stinner2019-09-231-41/+69
| | | | | | | | | | | | | | | | * _PyConfig_InitPathConfig() now starts by copying the global path configuration, and then override values set in PyConfig. * _PyPathConfig_Calculate() implementations no longer override _PyPathConfig fields which are already computed. For example, if _PyPathConfig.prefix is not NULL, leave it unchanged. * If Py_SetPath() has been called, _PyConfig_InitPathConfig() doesn't call _PyPathConfig_Calculate() anymore. * _PyPathConfig_Calculate() no longer uses PyConfig, except to initialize PyCalculatePath structure. * pathconfig_calculate(): remove useless temporary "_PyPathConfig new_config" variable. * calculate_module_search_path(): remove hack to workaround memory allocation failure, call Py_FatalError() instead. * Fix get_program_full_path(): handle memory allocation failure.
* bpo-38236: Dump path config at first import error (GH-16300)Victor Stinner2019-09-231-3/+2
| | | | Python now dumps path configuration if it fails to import the Python codecs of the filesystem and stdio encodings.
* bpo-38234: Fix PyConfig_Read() when Py_SetPath() was called (GH-16298)Victor Stinner2019-09-201-3/+6
| | | | | | * If Py_SetPath() has been called, _PyConfig_InitPathConfig() now uses its value. * Py_Initialize() now longer copies path configuration from PyConfig to the global path configuration (_Py_path_config).
* bpo-38234: Remove _PyPathConfig.dll_path (GH-16307)Victor Stinner2019-09-201-25/+34
| | | | | | | | | 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 Dower2019-06-291-3/+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.

| | | | | | | | | | | | | | 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-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

| | | | | | | | | | | | | | | | | | | | | | | | | | _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: 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
