* bpo-32030: Fix calculate_path() on macOS (#4526)Victor Stinner2017-11-231-8/+9

* bpo-32030: Rewrite calculate_path() (#4521)Victor Stinner2017-11-231-338/+517
| | | | | | | | | | | | | | | | | * calculate_path() rewritten in Modules/getpath.c and PC/getpathp.c * Move global variables into a new PyPathConfig structure. * calculate_path(): * Split the huge calculate_path() function into subfunctions. * Add PyCalculatePath structure to pass data between subfunctions. * Document PyCalculatePath fields. * Move cleanup code into a new calculate_free() subfunction * calculate_init() now handles Py_DecodeLocale() failures properly * calculate_path() is now atomic: only replace PyPathConfig (path_config) at once on success. * _Py_GetPythonHomeWithConfig() now returns an error on failure * Add _Py_INIT_NO_MEMORY() helper: report a memory allocation failure * Coding style fixes (PEP 7)
* bpo-32030: Add _PyMainInterpreterConfig.pythonhome (#4513)Victor Stinner2017-11-231-3/+3
| | | | | | | | | | | | * Py_Main() now reads the PYTHONHOME environment variable * Add _Py_GetPythonHomeWithConfig() private function * Add _PyWarnings_InitWithConfig() * init_filters() doesn't get the current core configuration from the current interpreter or Python thread anymore. Pass explicitly the configuration to _PyWarnings_InitWithConfig(). * _Py_InitializeCore() now fails on _PyWarnings_InitWithConfig() failure. * Pass configuration as constant
* bpo-32030: Move PYTHONPATH to _PyMainInterpreterConfig (#4511)Victor Stinner2017-11-231-9/+9
| | | | Move _PyCoreConfig.module_search_path_env to _PyMainInterpreterConfig structure.
* bpo-32030: Add _PyCoreConfig.module_search_path_env (#4504)Victor Stinner2017-11-231-18/+43
| | | | | | | | | | | Changes: * Py_Main() initializes _PyCoreConfig.module_search_path_env from the PYTHONPATH environment variable. * PyInterpreterState_New() now initializes core_config and config fields * Compute sys.path a little bit ealier in _Py_InitializeMainInterpreter() and new_interpreter() * Add _Py_GetPathWithConfig() private function.
* bpo-31532: Fix memory corruption due to allocator mix (#3679)nurelin2017-09-201-1/+1
| | | | | | | | | | | | Fix a memory corruption in getpath.c due to mixed memory allocators between Py_GetPath() and Py_SetPath(). The fix use the Raw allocator to mimic the windows version. This patch should be used from python3.6 to the current version for more details, see the bug report and https://github.com/pyinstaller/pyinstaller/issues/2812

* Issue #23731: Implement PEP 488.Brett Cannon2015-04-131-3/+2
| | | | | | The concept of .pyo files no longer exists. Now .pyc files have an optional `opt-` tag which specifies if any extra optimizations beyond the peepholer were applied.
* Issue #23753: Move _Py_wstat() from Python/fileutils.c to Modules/getpath.cVictor Stinner2015-03-241-0/+17
| | | | | | | I expected more users of _Py_wstat(), but in practice it's only used by Modules/getpath.c. Move the function because it's not needed on Windows. Windows uses PC/getpathp.c which uses the Win32 API (ex: GetFileAttributesW()) not the POSIX API.

Without this patch running python.exe from the build tree will fail when these tree conditions are true: 1) the CWD is not the root of build tree 2) python.exe is found through $PATH 3) the framework is not yet installed
