On error, call(), check_call(), check_output() and getstatusoutput() functions
of the subprocess module now kill the process, read its status (to avoid
zombis) and close pipes.
The right-hand part in [extension: foo] is now used as the name of the
extension module. (I changed the separator from = to : and allowed
whitespace to make the sections look nicer.)
This huge module is the heir of six distutils modules, and contains
a number of miscellaneous functions. I have attempted to help readers
of the source code with an annoted __all__. Removed or deprecated
functions have been removed from the documentation; I’m working on
another patch to document the remaining public functions.
For the curious:
The unzip_file and untar_file were used by (or intended to be used by)
“pysetup install path/to/archive.tar.gz”, but the code presently used
shutil.unpack_archive and an helper function, so I just deleted them.
They’re still in the repository if we need them in the future.
The find_packages function is not used anymore but I want to discuss
module and package auto-discovery (in “pysetup create”) again before
removing it.
subst_vars now lives in sysconfig; rfc822_escape is inlined in
packaging.metadata. Other functions are for internal use only, or
deprecated; I have left them out of __all__ and sprinkled TODO notes
for future cleanups.

- Issue #11241: subclasses of ctypes.Array can now be subclassed.
Windows does set the errno attribute to ENOENT, but the error message
displays the Windows error number (3 -> ERROR_PATH_NOT_FOUND), not the
errno number (2 -> ENOENT).
The Unix errno corresponding to 3 is ESRCH, explaining the confusion,
which can be seen in the following snippet:
>>> shutil.rmtree("foo")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "Z:\default\lib\shutil.py", line 272, in rmtree
onerror(os.listdir, path, sys.exc_info())
File "Z:\default\lib\shutil.py", line 270, in rmtree
names = os.listdir(path)
WindowsError: [Error 3] The system cannot find the path specified:
'foo\\*.*'
>>> e = sys.last_value
>>> e.errno
2
>>> e.winerror
3
>>> errno.errorcode[2]
'ENOENT'

There was already a test for this, but it was complicated and had a
subtle bug (custom command objects need to be put in dist.command_obj so
that other command objects may see them) that rendered it moot.
Packaging uses the shutil.make_archive function copied from distutils,
which does not support compress. There is no test to check that
“bdist --format whatever” works, so this slipped by.
These options were used to implement “setup.py --name”,
“setup.py --version”, etc. which are now handled by the pysetup metadata
action or direct parsing of the setup.cfg file.
As a side effect, the Distribution class no longer accepts a 'url' key
in its *attrs* argument: it has to be 'home-page' to be recognized as a
valid metadata field and passed down to the dist.metadata object.
I cleaned up some comments, docstrings and code along the way.
When called without option (“-f field” or “--all”), “pysetup metadata”
didn’t do anything useful. Now it prints out all metadata fields. The
“--all” option is removed.
