parameter from os.remove / os.unlink.
Patch written by Georg Brandl. (I'm really looking forward to George
getting commit privileges so I don't have to keep doing checkins on his
behalf.)
Many functions now support "dir_fd" and "follow_symlinks" parameters;
some also support accepting an open file descriptor in place of of a path
string. Added os.support_* collections as LBYL helpers. Removed many
functions only previously seen in 3.3 alpha releases (often starting with
"f" or "l", or ending with "at"). Originally suggested by Serhiy Storchaka;
implemented by Larry Hastings.
when the path existed and had the S_ISGID mode bit set when it was
not explicitly asked for. This is no longer an exception as mkdir
cannot control if the OS sets that bit for it or not.

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__().

The environment variable PYTHONHASHSEED and the new command line flag -R control this

called collections.abc, following the pattern used by importlib.abc. For
backwards compatibility, the names continue to also be imported into the
collections module.
Use only one global warning.catch_warnings() context, instead of two local
contexts. Improve also the explaination why the function uses a local import.
error handler, or strict error handler on Windows.
* Rewrite os.fsencode() documentation
* Improve os.fsencode and os.fsdecode() tests using the new PYTHONFSENCODING

subprocess.Popen() and os._execvpe() support bytes program name. Add
os.supports_bytes_environ flag: True if the native OS type of the environment
is bytes (eg. False on Windows).
Create os.environb mapping and os.getenvb() function, os.unsetenv() encodes str
argument to the file system encoding with the surrogateescape error handler
(instead of utf8/strict) and accepts bytes, and posix.environ keys and values
are bytes.

Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and
bytes strings for environment keys and values

Fix test_undecodable_env of test_subproces for non-ASCII directory
This test was introduced by r80421 (issue #8391).
The fix: copy the environment variables instead of starting Python in an empty
environement. In an empty environment, the locale is C and Python uses ASCII
for the default file system encoding. The non-ASCII directory will be encoded
using surrogates, but Python3 is unable to load a module or package with a
filename using surrogates.
See issue #8242 for more information about running Python3 with a non-ascii
directory in an empty environement.
