    Entries are subject to filtering and limits, see `add_match`, `this_boot`,
    `this_machine` functions and the `data_treshold` attribute.

    Note that in order to access the system journal, a non-root user must have
    the necessary privileges, see journalctl(1) for details.  Unprivileged users
    can access only their own journal.

    Example usage to print out all informational or higher level messages for
    systemd-udevd for this boot:

    >>> from systemd import journal
    >>> j = journal.Reader()
    >>> j.this_boot()
    >>> j.log_level(journal.LOG_INFO)
    >>> j.add_match(_SYSTEMD_UNIT="systemd-udevd.service")
    >>> for entry in j:                                 # doctest: +SKIP
    ...    print(entry['MESSAGE'])
    starting version ...

    See systemd.journal-fields(7) for more info on typical fields found in the
    journal.

        Argument `flags` defines the open flags of the journal, which can be one
        of, or ORed combination of constants: LOCAL_ONLY (default) opens journal
        on local machine only; RUNTIME_ONLY opens only volatile journal files;
        and SYSTEM_ONLY opens only journal files of system services and the kernel.

        Argument `path` is the directory of journal files, either a file system
        path or a file descriptor. Note that `flags`, `path`, and `files` are
        exclusive.

        Argument `converters` is a dictionary which updates the
        DEFAULT_CONVERTERS to convert journal field values. Field names are used
        as keys into this dictionary. The values must be single argument
        functions, which take a `bytes` object and return a converted
        value. When there's no entry for a field name, then the default UTF-8
        decoding will be attempted. If the conversion fails with a ValueError,
        unconverted bytes object will be returned. (Note that ValueEror is a
        superclass of UnicodeDecodeError).

        Reader implements the context manager protocol: the journal will be
        closed when exiting the block.

    >>> journal.send('Binary message', BINARY=b'\xde\xad\xbe\xef')

    Value of the MESSAGE argument will be used for the MESSAGE= field. MESSAGE
    must be a string and will be sent as UTF-8 to the journal.

    MESSAGE_ID can be given to uniquely identify the type of message. It must be
    a string or a uuid.UUID object.

    CODE_LINE, CODE_FILE, and CODE_FUNC can be specified to identify the caller.
    Unless at least on of the three is given, values are extracted from the
    stack frame of the caller of send(). CODE_FILE and CODE_FUNC must be
    strings, CODE_LINE must be an integer.

    Additional fields for the journal entry can only be specified as keyword
    arguments. The payload can be either a string or bytes. A string will be
    sent as UTF-8, and bytes will be sent as-is to the journal.

    Other useful fields include PRIORITY, SYSLOG_FACILITY, SYSLOG_IDENTIFIER,
    SYSLOG_PID.

tjd}t|||�}tj|dd�S)a�Return a file object wrapping a stream to journal.

    Log messages written to this file as simple newline sepearted text strings
    are written to the journal.

    The file will be line buffered, so messages are actually sent after a
    newline character is written.

    >>> from systemd import journal
    >>> stream = journal.stream('myapp')                       # doctest: +SKIP
    >>> res = stream.write('message...\n')                     # doctest: +SKIP

    will produce the following message in the journal::

      PRIORITY=7
      SYSLOG_IDENTIFIER=myapp
      MESSAGE=message...

    If identifier is None, a suitable default based on sys.argv[0] will be used.

    This interface can be used conveniently with the print function:

    >>> from __future__ import print_function
    >>> stream = journal.stream()                              # doctest: +SKIP
    >>> print('message...', file=stream)                       # doctest: +SKIP

    priority is the syslog priority, one of `LOG_EMERG`, `LOG_ALERT`,
    `LOG_CRIT`, `LOG_ERR`, `LOG_WARNING`, `LOG_NOTICE`, `LOG_INFO`, `LOG_DEBUG`.

    level_prefix is a boolean. If true, kernel-style log priority level prefixes
    (such as '<1>') are interpreted. See sd-daemon(3) for more information.

Z�ZS)�JournalHandlera�Journal handler class for the Python logging framework.

    Please see the Python logging module documentation for an overview:
    http://docs.python.org/library/logging.html.

    To create a custom logger whose messages go only to journal:

    >>> import logging
    >>> log = logging.getLogger('custom_logger_name')
    >>> log.propagate = False
    >>> log.addHandler(JournalHandler())
    >>> log.warning("Some message: %s", 'detail')

    Note that by default, message levels `INFO` and `DEBUG` are ignored by the
    logging framework. To enable those log levels:

    >>> log.setLevel(logging.DEBUG)

    To redirect all logging messages to journal regardless of where they come
    from, attach it to the root logger:

    >>> logging.root.addHandler(JournalHandler())

    For more complex configurations when using `dictConfig` or `fileConfig`,
    specify `systemd.journal.JournalHandler` as the handler class.  Only
    standard handler configuration options are supported: `level`, `formatter`,
    `filters`.

    To attach journal MESSAGE_ID, an extra field is supported:

    >>> import uuid
    >>> mid = uuid.UUID('0123456789ABCDEF0123456789ABCDEF')
    >>> log.warning("Message with ID", extra={'MESSAGE_ID': mid})

    Fields to be attached to all messages sent through this handler can be
    specified as keyword arguments. This probably makes sense only for
    SYSLOG_IDENTIFIER and similar fields which are constant for the whole
    program:

    >>> JournalHandler(SYSLOG_IDENTIFIER='my-cool-app')
    <...JournalHandler ...>

    The following journal fields will be sent: `MESSAGE`, `PRIORITY`,
    `THREAD_NAME`, `CODE_FILE`, `CODE_LINE`, `CODE_FUNC`, `LOGGER` (name as
    supplied to getLogger call), `MESSAGE_ID` (optional, see above),
    `SYSLOG_IDENTIFIER` (defaults to sys.argv[0]).

    The function used to actually send messages can be overridden using
    the `sender_function` parameter.
