Use Unicode for module name and paths in the following functions:
* PyImport_ImportModuleLevel()
* add_submodule()
* ensure_from_list()
* get_parent()
* import_module_level()
* import_submodule()
* load_next()
* mark_miss()
* Use Unicode for module name and path in the following functions:
* get_file()
* load_source_module(), parse_source_module()
* make_compiled_pathname(), check_compiled_module(),
read_compiled_module(), load_compiled_module(), write_compiled_module(),
update_compiled_module()
* On Windows, use CreateDirectoryW() instead of mkdir()
* update_compiled_module() cannot fail anymore
* Document the function
* Use RegQueryValueW() instead of RegQueryValueA()
* Use _Py_fopen() instead of fopen()
* Allocate registry key on the heap, not on the stack, and handle memory
allocation failure
* Handle Python exception in find_module()
- is_builtin(), init_builtin(), load_builtin() and other builtin related
functions use Unicode strings, instead of byte strings
- Rename _PyImport_FixupExtensionUnicode() to _PyImport_FixupExtensionObject()
- Rename _PyImport_FindExtensionUnicode() to _PyImport_FindExtensionObject()
And as a consequence, mark also name argument of
_PyImport_FindExtensionUnicode() constant too. But I plan to change this
argument type to PyObject* later.
* Rename _PyImport_FindExtension() to _PyImport_FindExtensionUnicode():
the filename becomes a Unicode object instead of byte string
* Rename _PyImport_FixupExtension() to _PyImport_FixupExtensionUnicode():
the filename becomes a Unicode object instead of byte string
filesystem encoding instead of utf-8.
imp_cache_from_source() encodes the input path to filesystem encoding and this
path is passed to make_compiled_pathname().
* _Py_fopen() and _Py_stat() come from Python/import.c
* (_Py)_wrealpath() comes from Python/sysmodule.c
* _Py_char2wchar(), _Py_wchar2char() and _Py_wfopen() come from Modules/main.c
* (_Py)_wstat(), (_Py)_wgetcwd(), _Py_wreadlink() come from Modules/getpath.c
fromlist to get __import__ to return the module desired. Now it uses the proper
approach of fetching the module from sys.modules.
Closes issue #9252. Thanks to Alexander Belopolsky for the bug report.
Call _wfopen() on Windows, or fopen() otherwise. Return the new file object on
success, or NULL if the file cannot be open or (if PyErr_Occurred()) on unicode
error.
* On non-Windows OSes: the constructor accepts bytes filenames
and use surrogateescape for unicode filenames
* On Windows: use GetFileAttributesW() instead of GetFileAttributesA()
