"""
Subprocesses with accessible I/O streams

This module allows you to spawn processes, connect to their
input/output/error pipes, and obtain their return codes.

For a complete description of this module see the Python documentation.

Main API
========
run(...): Runs a command, waits for it to complete, then returns a
          CompletedProcess instance.
Popen(...): A class for flexibly executing a command in a new process

Constants
---------
DEVNULL: Special value that indicates that os.devnull should be used
PIPE:    Special value that indicates a pipe should be created
STDOUT:  Special value that indicates that stderr should go to stdout


Older API
=========
call(...): Runs a command, waits for it to complete, then returns
    the return code.
check_call(...): Same as call() but raises CalledProcessError()
    if return code is not 0
check_output(...): Same as check_call() but returns the contents of
    stdout instead of a return code
getoutput(...): Runs a command in the shell, waits for it to complete,
    then returns the output
getstatusoutput(...): Runs a command in the shell, waits for it to complete,
    then returns a (exitcode, output) tuple

        The returned instance will have attributes args, returncode, stdout and
        stderr. By default, stdout and stderr are not captured, and those attributes
        will be None. Pass stdout=PIPE and/or stderr=PIPE in order to capture them.

        If check is True and the exit code was non-zero, it raises a
        CalledProcessError. The CalledProcessError object will have the return code
        in the returncode attribute, and output & stderr attributes if those streams
        were captured.

        If timeout is given, and the process takes too long, a TimeoutExpired
        exception will be raised.

        There is an optional argument "input", allowing you to
        pass bytes or a string to the subprocess's stdin.  If you use this argument
        you may not also use the Popen constructor's "stdin" argument, as
        it will be used internally.

        By default, all communication is in bytes, and therefore any "input" should
        be bytes, and the stdout and stderr will be bytes. If in text mode, any
        "input" should be a string, and stdout and stderr will be strings decoded
        according to locale encoding, or by "encoding" if set. Text mode is
        triggered by setting any of text, encoding, errors or universal_newlines.

        The other arguments are the same as for the Popen constructor.

        """Run command with arguments and return its output.

        If the exit code was non-zero it raises a CalledProcessError.  The
        CalledProcessError object will have the return code in the returncode
        attribute and output in the output attribute.

        The arguments are the same as for the Popen constructor.  Example:

        >>> check_output(["ls", "-l", "/dev/null"])
        b'crw-rw-rw- 1 root root 1, 3 Oct 18  2007 /dev/null\\n'

        The stdout argument is not allowed as it is used internally.
        To capture standard error in the result, use stderr=STDOUT.

        >>> check_output(["/bin/sh", "-c",
        ...               "ls -l non_existent_file ; exit 0"],
        ...              stderr=STDOUT)
        b'ls: non_existent_file: No such file or directory\\n'

        There is an additional optional argument, "input", allowing you to
        pass a string to the subprocess's stdin.  If you use this argument
        you may not also use the Popen constructor's "stdin" argument, as
        it too will be used internally.  Example:

        >>> check_output(["sed", "-e", "s/foo/bar/"],
        ...              input=b"when in the course of fooman events\\n")
        b'when in the course of barman events\\n'

        By default, all communication is in bytes, and therefore any "input"
        should be bytes, and the return value will be bytes.  If in text mode,
        any "input" should be a string, and the return value will be a string
        decoded according to locale encoding, or by "encoding" if set. Text mode
        is triggered by setting any of text, encoding, errors or universal_newlines.
