* gh-97758: Fix a crash in getpath_joinpath() called without arguments (GH-97759)Miss Islington (bot)2022-10-051-1/+1
| | | | | (cherry picked from commit f8cbd79d328d90443acabc41d246332c302c815a) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* gh-94526: getpath_dirname() no longer encodes the path (GH-97645)Miss Islington (bot)2022-09-301-9/+14
| | | | | | | | | | | | | | Fix the Python path configuration used to initialized sys.path at Python startup. Paths are no longer encoded to UTF-8/strict to avoid encoding errors if it contains surrogate characters (bytes paths are decoded with the surrogateescape error handler). getpath_basename() and getpath_dirname() functions no longer encode the path to UTF-8/strict, but work directly on Unicode strings. These functions now use PyUnicode_FindChar() and PyUnicode_Substring() on the Unicode path, rather than strrchr() on the encoded bytes string. (cherry picked from commit 9f2f1dd131b912e224cd0269adde8879799686c4) Co-authored-by: Victor Stinner <vstinner@python.org>
* bpo-46890: Fix setting of sys._base_executable with framework builds on ↵Ronald Oussoren2022-04-051-0/+6
| | | | | | | | | macOS (GH-31958) The side effect of this bug was that venv environments directly used the main interpreter instead of the intermediate stub executable, which can cause problems when a script uses system APIs that require the use of an application bundle.
* bpo-46362: Ensure ntpath.abspath() uses the Windows API correctly (GH-30571)neonene2022-01-131-3/+3
| | | This makes ntpath.abspath()/getpath_abspath() follow normpath(), since some WinAPIs such as PathCchSkipRoot() require backslashed paths.
* bpo-46049: Fixes ._pth support on non-Windows (GH-30051)Steve Dower2021-12-111-1/+1
|
* bpo-46048: Fix parsing of single character lines in getpath readlines() ↵Steve Dower2021-12-111-3/+3
| | | | (GH-30048)
* bpo-46015: Fixes calculation of sys.path in a venv on Windows (GH-29992)Steve Dower2021-12-081-1/+1
| | | Also ensures that pybuilddir.txt is written early enough in the build to be picked up by later steps.
* bpo-45582: Fix framework path and bootstrap build (GH-29954)Christian Heimes2021-12-071-9/+12
| | | | | | | * Check NS API return values for NULL to prevent segfault in ``_bootstrap_python``. * Set modPathInitialized to 1 so the ``decode_to_dict`` path is used. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-45582: framework build: modPath must not be const (GH-29944)Christian Heimes2021-12-061-1/+1

* bpo-45582: Fix out-of-tree build issues with new getpath (GH-29902)Christian Heimes2021-12-031-1/+1
|
* bpo-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-031-1397/+715
| | | | | 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-45506: Normalize _PyPathConfig.stdlib_dir when calculated. (#29040)Eric Snow2021-10-221-6/+40
| | | | | The recently added PyConfig.stdlib_dir was being set with ".." entries. When __file__ was added for from modules this caused a problem on out-of-tree builds. This PR fixes that by normalizing "stdlib_dir" when it is calculated in getpath.c. https://bugs.python.org/issue45506
* bpo-45434: pyport.h no longer includes <stdlib.h> (GH-28914)Victor Stinner2021-10-131-1/+2
| | | | | Include <stdlib.h> explicitly in C files. Python.h includes <wchar.h>.
* Fix typos in the Modules directory (GH-28761)Christian Clauss2021-10-071-1/+1
|
* bpo-45211: Remember the stdlib dir during startup. (gh-28586)Eric Snow2021-09-281-0/+10
| | | | | 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-45211: Move helpers from getpath.c to internal API. (gh-28550)Eric Snow2021-09-271-56/+8
| | | | | | | | | | | | This accomplishes 2 things: * consolidates some common code between getpath.c and getpathp.c * makes the helpers available to code in other files FWIW, the signature of the join_relfile() function (in fileutils.c) intentionally mirrors that of Windows' PathCchCombineEx(). Note that this change is mostly moving code around. No behavior is meant to change. https://bugs.python.org/issue45211
* bpo-44285: getpath.c: Assert that env_file is NULL during an error check ↵stratakis2021-06-021-0/+1
| | | | | (GH-26486) This was flagged by a static analyzer, but the logic of why this is NULL on error is hard to follow for humans as well.
* bpo-41100: Support macOS 11 and Apple Silicon (GH-22855)Ronald Oussoren2020-11-081-4/+0
| | | | | | | | | | | Co-authored-by: Lawrence D’Anna <lawrence_danna@apple.com> * Add support for macOS 11 and Apple Silicon (aka arm64) As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy * Support building on recent versions of macOS while deploying to older versions This allows building installers on macOS 11 while still supporting macOS 10.9.
* bpo-40947: getpath.c uses PyConfig.platlibdir (GH-20807)Victor Stinner2020-06-111-11/+20
| | | | | | | | | | | Followup of bpo-40854, there is one remaining usage of PLATLIBDIR which should be replaced by config->platlibdir. test_sys checks that sys.platlibdir attribute exists and is a string. Update Makefile: getpath.c and sysmodule.c no longer need PLATLIBDIR macro, PyConfig.platlibdir member is used instead. Co-authored-by: Sandro Mani <manisandro@gmail.com>
* bpo-40854: Allow overriding sys.platlibdir via PYTHONPLATLIBDIR env-var ↵Sandro Mani2020-06-081-10/+6

* bpo-40268: Remove unused osdefs.h includes (GH-19532)Victor Stinner2020-04-151-1/+1
| | | When the include is needed, add required symbol in a comment.
* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-141-3/+2
|
* bpo-1294959: Add sys.platlibdir attribute (GH-18381)Victor Stinner2020-03-101-12/+40
| | | | | | | | | | | | | Add --with-platlibdir option to the configure script: name of the platform-specific library directory, stored in the new sys.platlitdir attribute. It is used to build the path of platform-specific dynamic libraries and the path of the standard library. It is equal to "lib" on most platforms. On Fedora and SuSE, it is equal to "lib64" on 64-bit systems.

* bpo-38353: Fix typos in calculate_argv0_path_framework() (GH-16695)Victor Stinner2019-10-101-4/+4
| | | | | bpo-38353, bpo-38429: Fix typos introduced by commit c02b41b1fb115c87693530ea6a480b2e15460424 in calculate_argv0_path_framework() of getpath.c.
* bpo-38353: Simplify calculate_pybuilddir() (GH-16614)Victor Stinner2019-10-071-5/+0
| | | | Calling _Py_wfopen() is enough to check if filename is an existing file or not. There is no need to check first isfile().
* bpo-38353: getpath.c: allocates strings on the heap (GH-16585)Victor Stinner2019-10-041-295/+383
| | | | | | | | | | | * _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: getpath.c uses dynamically allocated strings (GH-16582)Victor Stinner2019-10-041-91/+115
| | | | * PyCalculatePath: add "_macro" to the 3 fields storing macro values * Add dynamically allocated strings to PyCalculatePath
* bpo-38353: Rework ismodule() in getpath.c (GH-16574)Victor Stinner2019-10-041-64/+80
| | | | * ismodule() no longer modify the input string. * copy_absolute(), joinpath(): rename parameters and local variables.
* bpo-38353: Add subfunctions to getpath.c (GH-16572)Victor Stinner2019-10-041-153/+259
| | | | | | | | | | | | | | Following symbolic links is now limited to 40 attempts, just to prevent loops. Add subfunctions: * Add resolve_symlinks() * Add calculate_argv0_path_framework() * Add calculate_which() * Add calculate_program_macos() Fix also _Py_wreadlink(): readlink() result type is Py_ssize_t, not int.
* bpo-38353: Fix calculate_argv0_path() for symlinks (GH-16549)Victor Stinner2019-10-031-1/+1
| | | | calculate_argv0_path() must read argv0_path link, not read program_full_path link.
* bpo-38234: Cleanup getpath.c (GH-16367)Victor Stinner2019-09-251-73/+116
| | | | | | | | | * 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: Add tests for Python init path config (GH-16358)Victor Stinner2019-09-241-3/+3

* bpo-38234: read_pth_file() now returns PyStatus (GH-16338)Victor Stinner2019-09-231-79/+112
| | | | | | | | | 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 Stinner2019-09-231-62/+78
| | | | | | | | | | | | | | | | * _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-38234: Fix PyConfig_Read() when Py_SetPath() was called (GH-16298)Victor Stinner2019-09-201-4/+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-20443: Fix calculate_program_full_path() warning (GH-14446)Victor Stinner2019-06-281-1/+1
| | | | Don't call _Py_isabs() with a bytes string (char*), the function expects as wide string.
* bpo-20443: _PyConfig_Read() gets the absolute path of run_filename (GH-14053)Victor Stinner2019-06-251-8/+8
| | | | | | | | | | | | Python now gets the absolute path of the script filename specified on the command line (ex: "python3 script.py"): the __file__ attribute of the __main__ module, sys.argv[0] and sys.path[0] become an absolute path, rather than a relative path. * Add _Py_isabs() and _Py_abspath() functions. * _PyConfig_Read() now tries to get the absolute path of run_filename, but keeps the relative path if _Py_abspath() fails. * Reimplement os._getfullpathname() using _Py_abspath(). * Use _Py_isabs() in getpath.c.
* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-238/+238
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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()

| | | | | | | | | | | | | | | * 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 _Py_InitializeMain() (GH-13362)Victor Stinner2019-05-161-3/+3
| | | | | | | | | * 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-36763: Rework _PyInitError API (GH-13031)Victor Stinner2019-05-011-2/+2
| | | | | | | | | * Remove _PyInitError.user_err field and _Py_INIT_USER_ERR() macro: use _Py_INIT_ERR() instead. _Py_ExitInitError() now longer calls abort() on error: exit with exit code 1 instead. * Add _PyInitError._type private field. * exitcode field type is now unsigned int on Windows. * Rename prefix field to _func. * Rename msg field to err_msg.
* bpo-36352: Avoid hardcoded MAXPATHLEN size in getpath.c (GH-12423)Victor Stinner2019-03-191-150/+234
| | | | * Use Py_ARRAY_LENGTH() rather than hardcoded MAXPATHLEN in getpath.c. * Pass string length to functions modifying strings.
