Run Python in isolated mode. This also implies -E and -s. In isolated mode
sys.path contains neither the script’s directory nor the user’s
site-packages directory. All PYTHON* environment variables are ignored,
too. Further restrictions may be imposed to prevent the user from
injecting malicious code.
PyStructSequence_InitType() except that it has a return value (0 on success,
-1 on error).
* PyStructSequence_InitType2() now raises MemoryError on memory allocation failure
* Fix also some calls to PyDict_SetItemString(): handle error
_PyDict_GetItemId() is more efficient: it only builds the Unicode string once.
Identifiers (dictionary keys) are now created at Python initialization, and if
the creation failed, Python does exit with a fatal error.
Before, PyDict_GetItemString() failure was not handled: structseq_new() could
call PyObject_GC_NewVar() with a negative size, and structseq_dealloc() could
also crash.
attributes to None.
The long-term goal is for people to be able to rely on these
attributes existing and checking for None to see if they have been
set. Since import itself sets these attributes when a loader does not
the only instances when the attributes are None are from someone
overloading __import__() and not using a loader or someone creating a
module from scratch.
This patch also unifies module initialization. Before you could have
different attributes with default values depending on how the module
object was created. Now the only way to not get the same default set
of attributes is to circumvent initialization by calling
ModuleType.__new__() directly.
faulthandler requires the importlib if "-X faulthandler" option is present on
the command line, so initialize faulthandler after importlib.
Add also an unit test.
be implicit.
Added a warning for when sys.path_hooks is found to be empty. Also
changed the meaning of None in sys.path_importer_cache to represent
trying sys.path_hooks again (an interpretation of previous semantics).
Also added a warning for when None was found.
The long-term goal is for None in sys.path_importer_cache to represent
the same as imp.NullImporter: no finder found for that sys.path entry.
rewriting functionality in pure Python.
To start, imp.new_module() has been rewritten in pure Python, put into
importlib (privately) and then publicly exposed in imp.
importlib._bootstrap is now frozen into Python/importlib.h and stored
as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen
code along with sys and imp and then uses _frozen_importlib._install()
to set builtins.__import__() w/ _frozen_importlib.__import__().
in order to make algorithmic complexity attacks on (e.g.) web apps much more complicated.
The environment variable PYTHONHASHSEED and the new command line flag -R control this
behavior.

Windows if the mbcs codec is not available, and fail with a fatal error if we
cannot get the locale encoding (if nl_langinfo(CODESET) is not available)
instead of using UTF-8.
* Set the default value of all_threads arguments to True
* Py_FatalError() dumps all threads, instead of only the current thread
Dump only the current thread is not reliable. In some cases, Python is unable
to retrieve the state of the current thread and so is unable to dump the
traceback. faulthandler keeps a reference to the interpreter and so is always
able to dump the traceback of all threads.

* 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
* PyUnicode_EncodeFSDefault(), PyUnicode_DecodeFSDefaultAndSize() and
PyUnicode_DecodeFSDefault() use the locale encoding instead of UTF-8 if
Py_FileSystemDefaultEncoding is NULL
* redecode_filenames() functions and _Py_code_object_list (issue #9630)
are no more needed: remove them
Redecode the filenames of:
- all modules: __file__ and __path__ attributes
- all code objects: co_filename attribute
- sys.path
- sys.meta_path
- sys.executable
- sys.path_importer_cache (keys)
Keep weak references to all code objects until initfsencoding() is called, to
be able to redecode co_filename attribute of all code objects.

POSIX systems with a C extension module. This is required in order for
the subprocess module to be made thread safe.
The pure python implementation is retained so that it can continue to be
used if for some reason the _posixsubprocess extension module is not
available.
The unittest executes tests on both code paths to guarantee compatibility.
