Command-line parsing library

This module is an optparse-inspired command-line parsing library that:

    - handles both optional and positional arguments
    - produces highly informative usage messages
    - supports parsers that dispatch to sub-parsers

The following is a simple usage example that sums integers from the
command-line and writes the result to a file::

    parser = argparse.ArgumentParser(
        description='sum the integers at the command line')
    parser.add_argument(
        'integers', metavar='int', nargs='+', type=int,
        help='an integer to be summed')
    parser.add_argument(
        '--log', default=sys.stdout, type=argparse.FileType('w'),
        help='the file where the sum should be written')
    args = parser.parse_args()
    args.log.write('%s' % sum(args.integers))
    args.log.close()

The module contains the following public classes:

    - ArgumentParser -- The main entry point for command-line parsing. As the
        example above shows, the add_argument() method is used to populate
        the parser with actions for optional and positional arguments. Then
        the parse_args() method is invoked to convert the args at the
        command-line into an object with attributes.

    - ArgumentError -- The exception raised by ArgumentParser objects when
        there are errors with the parser's actions. Errors raised while
        parsing the command-line are caught by ArgumentParser and emitted
        as command-line messages.

    - FileType -- A factory for defining types of files to be created. As the
        example above shows, instances of FileType are typically passed as
        the type= argument of add_argument() calls.

    - Action -- The base class for parser actions. Typically actions are
        selected by passing strings like 'store_true' or 'append_const' to
        the action= argument of add_argument(). However, for greater
        customization of ArgumentParser actions, subclasses of Action may
        be defined and passed as the action= argument.

    - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter,
        ArgumentDefaultsHelpFormatter -- Formatter classes which
        may be passed as the formatter_class= argument to the
        ArgumentParser constructor. HelpFormatter is the default,
        RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser
        not to change the formatting for help text, and
        ArgumentDefaultsHelpFormatter adds information about argument defaults
        to the help.

All other classes in this module are considered implementation details.
(Also note that HelpFormatter and RawDescriptionHelpFormatter are only
considered public as object names -- the API of the formatter objects is
still considered an implementation detail.)

    Action objects are used by an ArgumentParser to represent the information
    needed to parse a single argument from one or more strings from the
    command line. The keyword arguments to the Action constructor are also
    all attributes of Action instances.

    Keyword Arguments:

        - option_strings -- A list of command-line option strings which
            should be associated with this action.

        - dest -- The name of the attribute to hold the created object(s)

        - nargs -- The number of command-line arguments that should be
            consumed. By default, one argument will be consumed and a single
            value will be produced.  Other values include:
                - N (an integer) consumes N arguments (and produces a list)
                - '?' consumes zero or one arguments
                - '*' consumes zero or more arguments (and produces a list)
                - '+' consumes one or more arguments (and produces a list)
            Note that the difference between the default and nargs=1 is that
            with the default, a single value will be produced, while with
            nargs=1, a list containing a single value will be produced.

        - const -- The value to be produced if the option is specified and the
            option uses an action that takes no values.

        - default -- The value to be produced if the option is not specified.

        - type -- A callable that accepts a single string argument, and
            returns the converted value.  The standard Python types str, int,
            float, and complex are useful examples of such callables.  If None,
            str is used.

        - choices -- A container of values that should be allowed. If not None,
            after a command-line argument has been converted to the appropriate
            type, an exception will be raised if it is not a member of this
            collection.

        - required -- True if the action must always be specified at the
            command line. This is only meaningful for optional command-line
            arguments.

        - help -- The help string describing the argument.

        - metavar -- The name to be used for the option's argument with the
            help string. If None, the 'dest' value will be used as the name.

�ZdS)ra�Factory for creating file object types

    Instances of FileType are typically passed as type= arguments to the
    ArgumentParser add_argument() method.

    Keyword Arguments:
        - mode -- A string indicating how the file is to be opened. Accepts the
            same values as the builtin open() function.
        - bufsize -- The file's desired buffer size. Accepts the same values as
            the builtin open() function.
        - encoding -- The file's encoding. Accepts the same values as the
            builtin open() function.
        - errors -- A string indicating how encoding and decoding errors are to
            be handled. Accepts the same value as the builtin open() function.

The event loop can be broken up into a multiplexer (the part
responsible for notifying us of I/O events) and the event loop proper,
which wraps a multiplexer with functionality for scheduling callbacks,
immediately or at a given time in the future.

Whenever a public API takes a callback, subsequent positional
arguments will be passed to the callback if/when it is called.  This
avoids the proliferation of trivial lambdas implementing closures.
Keyword arguments for the callback are not supported; this is a
conscious design decision, leaving the door open for keyword arguments
to modify the meaning of the API call itself.

        Return the total number of bytes which were sent.

        The method uses high-performance os.sendfile if available.

        file must be a regular file object opened in binary mode.

        offset tells from where to start reading the file. If specified,
        count is the total number of bytes to transmit as opposed to
        sending the file until EOF is reached. File position is updated on
        return or also in case of error in which case file.tell()
        can be used to figure out the number of bytes
        which were sent.

        fallback set to True makes asyncio to manually read and send
        the file when the platform does not support the sendfile syscall
        (e.g. Windows or SSL socket on Unix).

        Raise SendfileNotAvailableError if the system does not support
        sendfile syscall and fallback is False.

�st�dS)adA coroutine which creates a TCP server bound to host and port.

        The return value is a Server object which can be used to stop
        the service.

        If host is an empty string or None all interfaces are assumed
        and a list of multiple sockets will be returned (most likely
        one for IPv4 and another one for IPv6). The host parameter can also be
        a sequence (e.g. list) of hosts to bind to.

        family can be set to either AF_INET or AF_INET6 to force the
        socket to use IPv4 or IPv6. If not set it will be determined
        from host (defaults to AF_UNSPEC).

        flags is a bitmask for getaddrinfo().

        sock can optionally be specified in order to use a preexisting
        socket object.

        backlog is the maximum number of queued connections passed to
        listen() (defaults to 100).

        ssl can be set to an SSLContext to enable SSL over the
        accepted connections.

        reuse_address tells the kernel to reuse a local socket in
        TIME_WAIT state, without waiting for its natural timeout to
        expire. If not specified will automatically be set to True on
        UNIX.

        reuse_port tells the kernel to allow this endpoint to be bound to
        the same port as other existing endpoints are bound to, so long as
        they all set this flag when being created. This option is not
        supported on Windows.

        ssl_handshake_timeout is the time in seconds that an SSL server
        will wait for completion of the SSL handshake before aborting the
        connection. Default is 60s.

        start_serving set to True (default) causes the created server
        to start accepting connections immediately.  When set to False,
        the user should await Server.start_serving() or Server.serve_forever()
        to make the server to start accepting connections.

        server socket to.

        sock can optionally be specified in order to use a preexisting

        This method will try to establish the endpoint in the background.

        protocol_factory must be a callable returning a protocol instance.

        socket family AF_INET, socket.AF_INET6 or socket.AF_UNIX depending on
        host (or family if specified), socket type SOCK_DGRAM.

        reuse_address tells the kernel to reuse a local socket in

        supported on Windows and some UNIX's. If the
        :py:data:`~socket.SO_REUSEPORT` constant is not defined then this
        capability is unsupported.

        allow_broadcast tells the kernel to allow this endpoint to send

    Differences:

    - This class is not thread-safe.

    - result() and exception() do not take a timeout argument and
      raise an exception when the future isn't done yet.

    - Callbacks registered with add_done_callback() are always called
      via the event loop's call_soon().

    - This class is not compatible with the wait() and as_completed()
      methods in the concurrent.futures package.

S)ra�Primitive lock objects.

    A primitive lock is a synchronization primitive that is not owned
    by a particular coroutine when locked.  A primitive lock is in one
    of two states, 'locked' or 'unlocked'.

    It is created in the unlocked state.  It has two basic methods,
    acquire() and release().  When the state is unlocked, acquire()
    changes the state to locked and returns immediately.  When the
    state is locked, acquire() blocks until a call to release() in
    another coroutine changes it to unlocked, then the acquire() call
    resets it to locked and returns.  The release() method should only
    be called in the locked state; it changes the state to unlocked
    and returns immediately.  If an attempt is made to release an
    unlocked lock, a RuntimeError will be raised.

    When more than one coroutine is blocked in acquire() waiting for
    the state to turn to unlocked, only one coroutine proceeds when a
    release() call resets the state to unlocked; first coroutine which
    is blocked in acquire() is being processed.

    acquire() is a coroutine and should be called with 'await'.

    Locks also support the asynchronous context management protocol.
    'async with lock' statement should be used.

    Usage:

        lock = Lock()
        ...
        await lock.acquire()
        try:
            ...
        finally:
            lock.release()

    Context manager usage:

        lock = Lock()
        ...
        async with lock:
             ...

    Lock objects can be tested for locking state:

        if not lock.locked():
           await lock.acquire()
        else:
           # lock is acquired
           ...

S)raA Semaphore implementation.

    A semaphore manages an internal counter which is decremented by each
    acquire() call and incremented by each release() call. The counter
    can never go below zero; when acquire() finds that it is zero, it blocks,
    waiting until some other thread calls release().

    Semaphores also support the context management protocol.

    The optional argument gives the initial value for the internal
    counter; it defaults to 1. If the value given is less than 0,
    ValueError is raised.

�ZdS)raCommon base class for protocol interfaces.

    Usually user implements protocols that derived from BaseProtocol
    like Protocol or ProcessProtocol.

    The only case when BaseProtocol should be implemented directly is
    write-only transport like write pipe
    �cCsdS)z�Called when a connection is made.

        The argument is the transport representing the pipe connection.
        To receive data, wait for data_received() calls.
        When the connection is closed, connection_lost() is called.
        Nr)�self�	transportrr�'/usr/lib/python3.8/asyncio/protocols.py�connection_madeszBaseProtocol.connection_madecCsdS)z�Called when the connection is lost or closed.

        The argument is an exception object or None (the latter
        meaning a regular EOF is received or the connection was
        aborted or closed).
        Nr�r�excrrr	�connection_lostszBaseProtocol.connection_lostcCsdS)aCalled when the transport's buffer goes over the high-water mark.

        Pause and resume calls are paired -- pause_writing() is called
        once when the buffer goes strictly over the high-water mark
        (even if subsequent writes increases the buffer size even
        more), and eventually resume_writing() is called once when the
        buffer size reaches the low-water mark.

        Note that if the buffer size equals the high-water mark,
        pause_writing() is not called -- it must go strictly over.
        Conversely, resume_writing() is called when the buffer size is
        equal or lower than the low-water mark.  These end conditions
        are important to ensure that things go as expected when either
        mark is zero.

        NOTE: This is the only Protocol callback that is not called
        through EventLoop.call_soon() -- if it were, it would have no
        effect when it's most needed (when the app keeps writing
        without yielding until pause_writing() is called).
        Nr�rrrr	�

    The user should implement this interface.  They can inherit from
    this class but don't need to.  The implementations here do
    nothing (they don't raise exceptions).

    When the user wants to requests a transport, they pass a protocol
    factory to a utility function (e.g., EventLoop.create_connection()).

    When the connection is made successfully, connection_made() is
    called with a suitable transport object.  Then data_received()
    will be called 0 or more times with data (bytes) received from the
    transport; finally, connection_lost() will be called exactly once
    with either an exception object or None as an argument.

    State machine of calls:

      start -> CM [-> DR*] [-> ER?] -> CL -> end

    * CM: connection_made()
    * DR: data_received()
    * ER: eof_received()
    * CL: connection_lost()
    rcCsdS)zTCalled when some data is received.

        The argument is a bytes object.
        Nr)r�datarrr	�
data_received^szProtocol.data_receivedcCsdS�z�Called when the other end calls write_eof() or equivalent.

        If this returns a false value (including None), the transport
        will close itself.  If it returns a true value, closing the
        transport is up to the protocol.

ra�Interface for stream protocol with manual buffer control.

    Important: this has been added to asyncio in Python 3.7
    *on a provisional basis*!  Consider it as an experimental API that
    might be changed or removed in Python 3.8.

    Event methods, such as `create_server` and `create_connection`,
    accept factories that return protocols that implement this interface.

    The idea of BufferedProtocol is that it allows to manually allocate
    and control the receive buffer.  Event loops can then use the buffer
    provided by the protocol to avoid unnecessary data copies.  This
    can result in noticeable performance improvement for protocols that
    receive big amounts of data.  Sophisticated protocols can allocate
    the buffer only once at creation time.

    State machine of calls:

      start -> CM [-> GB [-> BU?]]* [-> ER?] -> CL -> end

    * CM: connection_made()
    * GB: get_buffer()
    * BU: buffer_updated()
    * ER: eof_received()
    * CL: connection_lost()
    rcCsdS)aPCalled to allocate a new receive buffer.

        *sizehint* is a recommended minimal size for the returned
        buffer.  When set to -1, the buffer size can be arbitrary.

        Must return an object that implements the
        :ref:`buffer protocol <bufferobjects>`.
        It is an error to return a zero-sized buffer.

    If maxsize is less than or equal to zero, the queue size is infinite. If it
    is an integer greater than 0, then "await put()" will block when the
    queue reaches maxsize, until an item is removed by get().

    Unlike the standard library Queue, you can reliably know this Queue's size
    with qsize(), since your single-threaded asyncio application won't be
    interrupted between calling qsize() and doing an operation on the Queue.

ddd�Zddd�ZdS)�_SSLPipeaAn SSL "Pipe".

    An SSL pipe allows you to communicate with an SSL/TLS protocol instance
    through memory buffers. It can be used to implement a security layer for an
    existing connection where you don't have access to the connection's file
    descriptor, or for some reason you don't want to use it.

    An SSL pipe can be in "wrapped" and "unwrapped" mode. In unwrapped mode,
    data is passed through untransformed. In wrapped mode, application level
    data is encrypted to SSL record level data and vice versa. The SSL record
    level is the lowest level in the SSL protocol suite and is what travels
    as-is over the wire.

    An SslPipe initially is in "unwrapped" mode. To start SSL, call
    do_handshake(). To shutdown SSL again, call unwrap().
    iNcCsH||_||_||_t|_t��|_t��|_d|_	d|_

        The *context* argument specifies the ssl.SSLContext to use.

        The *server_side* argument indicates whether this is a server side or
        client side transport.

        The optional *server_hostname* argument can be used to specify the
        hostname you are connecting to. You may only specify this parameter if
        the _ssl module supports Server Name Indication (SNI).

        The data must be a bytes instance. It is OK to send an empty bytes
        instance. This can be used to get ssldata for a handshake initiated by

        Return a (ssldata, appdata) tuple. The ssldata element is a list of
        buffers containing SSL data that needs to be sent to the remote SSL.

        The appdata element is a list of buffers containing plaintext data that
        needs to be forwarded to the application. The appdata list may contain
        an empty buffer indicating an SSL "close_notify" alert. This alert must
        be acknowledged by calling shutdown().

        Return an (ssldata, offset) tuple. The ssldata element is a list of
        buffers containing record level data that needs to be sent to the
        remote SSL instance. The offset is the number of plaintext bytes that
        were processed, which may be less than the length of data.

        NOTE: In case of short writes, this call MUST be retried with the SAME
        buffer passed into the *data* argument (i.e. the id() must be the
        same). This is an OpenSSL requirement. A further particularity is that
        a short write will always have offset == 0, because the _ssl module
        does not enable partial writes. And even though the offset is zero,
        there will still be encrypted data in ssldata.

        These two values control when to call the protocol's

        the low-water limit must be less than or equal to the
        high-water limit.  Neither value can be negative.

        The defaults are implementation-specific.  If only the
        high-water limit is given, the low-water limit defaults to an
        implementation-specific value less than or equal to the
        high-water limit.  Setting high to zero forces low to zero as
        well, and causes pause_writing() to be called whenever the
        buffer becomes non-empty.  Setting low to zero causes
        resume_writing() to be called only once the buffer is empty.
        Use of zero for either limit is generally sub-optimal as it
        reduces opportunities for doing I/O and computation

�r�|��s�|��r�|���q�ql���fW�S�D]}|�	�q�XdS)a�Run coroutines with staggered start times and take the first to finish.

    This method takes an iterable of coroutine functions. The first one is
    started immediately. From then on, whenever the immediately preceding one
    fails (raises an exception), or when *delay* seconds has passed, the next
    coroutine is started. This continues until one of the coroutines complete
    successfully, in which case all others are cancelled, or until all
    coroutines fail.

    The coroutines provided should be well-behaved in the following way:

    * They should only ``return`` if completed successfully.

    * They should always raise an exception if they did not complete
      successfully. In particular, if they handle cancellation, they should
      probably reraise, like this::

        try:
            # do work
        except asyncio.CancelledError:
            # undo partially completed work
            raise

    Args:
        coro_fns: an iterable of coroutine functions, i.e. callables that
            return a coroutine object when called. Use ``functools.partial`` or
            lambdas to pass arguments.

        delay: amount of time, in seconds, between starting coroutines. If
            ``None``, the coroutines will run sequentially.

        loop: the event loop to use.

    Returns:
        tuple *(winner_result, winner_index, exceptions)* where

        - *winner_result*: the result of the winning coroutine, or ``None``
          if no coroutines won.

        - *winner_index*: the index of the winning coroutine in
          ``coro_fns``, or ``None`` if no coroutines won. If the winning
          coroutine may return None on success, *winner_index* can be used
          to definitively determine whether any coroutine won.

        - *exceptions*: list of exceptions returned by the coroutines.
          ``len(exceptions)`` is equal to the number of coroutines actually
          started, and the order is the same as in ``coro_fns``. The winning
          coroutine's entry is ``None``.

    The reader returned is a StreamReader instance; the writer is a

    with various optional keyword arguments following.

    Additional optional keyword arguments are loop (to set the event loop
    instance to use) and limit (to set the buffer limit passed to the
    StreamReader).

    (If you want to customize the StreamReader and/or
    StreamReaderProtocol classes, just copy the code -- there's

    The first parameter, `client_connected_cb`, takes two parameters:
    client_reader, client_writer.  client_reader is a StreamReader
    object, while client_writer is a StreamWriter object.  This
    parameter can either be a plain callback function or a coroutine;
    if it is a coroutine, it will be automatically converted into a
    Task.

    The rest of the arguments are all the usual arguments to
    loop.create_server() except protocol_factory; most common are
    positional host and port, with various optional keyword arguments
    following.  The return value is the same as loop.create_server().

    Additional optional keyword arguments are loop (to set the event loop
    instance to use) and limit (to set the buffer limit passed to the
    StreamReader).

    The return value is the same as loop.create_server(), i.e. a
    Server object which can be used to stop the service.

        separator at the end.

        Configured stream limit is used to check result. Limit sets the
        maximal length of data that can be returned, not counting the
        separator.

        an IncompleteReadError exception will be raised, and the internal
        buffer will be reset.  The IncompleteReadError.partial attribute
        may contain the separator partially.

        If the data cannot be read because of over limit, a
        LimitOverrunError exception  will be raised, and the data
        will be left in the internal buffer, so it can be read again.

        terminated by an exception, this returns the list of traceback
        frames.

        The frames are always ordered from oldest to newest.

        The optional limit gives the maximum number of frames to
        return; by default all available frames are returned.  Its
        meaning differs depending on whether a stack or a traceback is
        returned: the newest frames of a stack are returned, but the
        oldest frames of a traceback are returned.  (This matches the
        behavior of the traceback module.)

        to which the output is written; by default output is written

        This arranges for a CancelledError to be thrown into the
        wrapped coroutine on the next cycle through the event loop.
        The coroutine then has a chance to clean up or even deny
        the request using try/except/finally.

        Unlike Future.cancel, this does not guarantee that the
        task will be cancelled: the exception might be caught and
        acted upon, delaying cancellation of the task or preventing
        cancellation completely.  The task may also return a value or
        raise a different exception.

        Immediately after this method is called, Task.cancelled() will
        not return True (unless the task was already cancelled).  A
        task will be marked as cancelled when the wrapped coroutine
        terminates with a CancelledError exception (even if cancel()

    When waiting for the yielded coroutines you'll get the results (or

    in which and as soon as they complete.

    This differs from PEP 3148; the proper way to use this is:

        for f in as_completed(fs):
            result = await f  # The 'await' may raise.
            # Use result.

    If a timeout is specified, the 'await' will raise
    TimeoutError when the timeout occurs before all Futures are done.

�|d���S)a�Return a future aggregating results from the given coroutines/futures.

    Coroutines will be wrapped in a future and scheduled in the event
    loop. They will not necessarily be scheduled in the same order as
    passed in.

    All futures must share the same event loop.  If all the tasks are
    done successfully, the returned future's result is the list of
    results (in the order of the original sequence, not necessarily
    the order of results arrival).  If *return_exceptions* is True,
    exceptions in the tasks are treated the same as successful
    results, and gathered in the result list; otherwise, the first
    raised exception will be immediately propagated to the returned
    future.

    Cancellation: if the outer Future is cancelled, all children (that
    have not completed yet) are also cancelled.  If any child is
    cancelled, this is treated as if it raised CancelledError --
    the outer Future is *not* cancelled in this case.  (This is to
    prevent the cancellation of one child to cause other children to
    be cancelled.)

    If *return_exceptions* is False, cancelling gather() after it
    has been marked done won't cancel any submitted awaitables.
    For instance, gather can be marked done after propagating an
    exception to the caller, therefore, calling ``gather.cancel()``
    after catching an exception (raised by one of the awaitables) from
    gather won't cancel any other awaitables.

a.Wait for a future, shielding it from cancellation.

    The statement

        res = await shield(something())

    is exactly equivalent to the statement

        res = await something()

    *except* that if the coroutine containing it is cancelled, the
    task running in something() is not cancelled.  From the POV of
    something(), the cancellation did not happen.  But its caller is
    still cancelled, so the yield-from expression still raises
    CancelledError.  Note: If something() is cancelled by other means
    this will still cancel shield().

    If you want to completely ignore cancellation (not recommended)
    you can combine shield() with a try/except clause, as follows:

        try:
            res = await shield(something())
        except CancelledError:

        These two values control when to call the protocol's

        the low-water limit must be less than or equal to the
        high-water limit.  Neither value can be negative.

        The defaults are implementation-specific.  If only the
        high-water limit is given, the low-water limit defaults to an
        implementation-specific value less than or equal to the
        high-water limit.  Setting high to zero forces low to zero as
        well, and causes pause_writing() to be called whenever the
        buffer becomes non-empty.  Setting low to zero causes
        resume_writing() to be called only once the buffer is empty.
        Use of zero for either limit is generally sub-optimal as it
        reduces opportunities for doing I/O and computation

    There may be several implementations, but typically, the user does
    not implement new transports; rather, the platform provides some
    useful transports that are implemented using the platform's best
    practices.

    The user never instantiates a transport directly; they call a
    utility function, passing it a protocol factory and other
    information necessary to create the transport and protocol.  (E.g.
    EventLoop.create_connection() or EventLoop.create_server().)

    The utility function will asynchronously create a transport and a
    protocol and hook them up by calling the protocol's
    connection_made() method, passing it the transport.

    process must be done within a 'with' block to allow the watcher to suspend
    its activity until the new process if fully registered (this is needed to
    prevent a race condition in some implementations).

    Example:
        with watcher:
            proc = subprocess.Popen("sleep 1")
            watcher.add_child_handler(proc.pid, callback)

    Notes:
        Implementations of this class must be thread-safe.

        Since child watcher objects may catch the SIGCHLD signal and call
        waitpid(-1), there should be only one active object per process.
    cGs
t��dS)aRegister a new child handler.

        Arrange for callback(pid, returncode, *args) to be called when
        process 'pid' terminates. Specifying another callback for the same
        process replaces the previous handler.

Executor.submit() called:
- creates a uniquely numbered _WorkItem and adds it to the "Work Items" dict
- adds the id of the _WorkItem to the "Work Ids" queue

Local worker thread:
- reads work ids from the "Work Ids" queue and looks up the corresponding
  WorkItem from the "Work Items" dict: if the work item has been cancelled then
  it is simply removed from the dict, otherwise it is repackaged as a
  _CallItem and put in the "Call Q". New _CallItems are put in the "Call Q"
  until "Call Q" is full. NOTE: the size of the "Call Q" is kept small because
  calls placed in the "Call Q" can no longer be cancelled with Future.cancel().
- reads _ResultItems from "Result Q", updates the future stored in the
  "Work Items" dict and deletes the dict entry

Process #1..n:
- reads _CallItems from "Call Q", executes the calls, and puts the resulting
  _ResultItems in "Result Q"

zProcessPoolExecutor.submitr&)�timeoutrVcs:|dkrtd��t�jtt|�t|d|i�|d�}t|�S)ajReturns an iterator equivalent to map(fn, iter).

        Args:
            fn: A callable that will take as many arguments as there are
                passed iterables.
            timeout: The maximum number of seconds to wait. If None, then there
                is no limit on the wait time.
            chunksize: If greater than one, the iterables will be chopped into
                chunks of size chunksize and submitted to the process pool.
                If set to one, the items in the list will be sent one at a time.

        Returns:
            An iterator equivalent to: map(func, *iterables) but the calls may
            be evaluated out-of-order.

        Raises:
            TimeoutError: If the entire result iterator could not be generated
                before the given timeout.

|���YnX||||fS)a�Decode encoded word and return (string, charset, lang, defects) tuple.

    An RFC 2047/2243 encoded word has the form:

        =?charset*lang?cte?encoded_string?=

    where '*lang' may be omitted but the other parts may not be.

    This function expects exactly such a string (that is, it does not check the
    syntax and may raise errors if the string is not well formed), and returns
    the encoded_string decoded first from its Content Transfer Encoding and
    then from the resulting bytes into unicode using the specified charset.  If
    the cte-decoded string does not successfully decode using the specified
    character set, a defect is added to the defects list and the unknown octets
    are replaced by the unicode 'unknown' character \uFDFF.

    The specified charset and language are returned.  The default for language,
    which is rarely if ever encountered, is the empty string.

aEncode string using the CTE encoding that produces the shorter result.

    Produces an RFC 2047/2243 encoded word of the form:

        =?charset*lang?cte?encoded_string?=

    where '*lang' is omitted unless the 'lang' parameter is given a value.
    Optional argument charset (defaults to utf-8) specifies the charset to use
    to encode the string to binary before CTE encoding it.  Optional argument
    'encoding' is the cte specifier for the encoding that should be used ('q'
    or 'b'); if it is None (the default) the encoding which produces the
    shortest encoded sequence is used, except that 'q' is preferred if it is up
    to five characters longer.  Optional argument 'lang' (default '') gives the
    RFC 2243 language string to specify in the encoded word.

The parsing methods defined in this module implement various email related
parsing rules.  Principal among them is RFC 5322, which is the followon
to RFC 2822 and primarily a clarification of the former.  It also implements
RFC 2047 encoded word decoding.

RFC 5322 goes to considerable trouble to maintain backward compatibility with
RFC 822 in the parse phase, while cleaning up the structure on the generation
phase.  This parser supports correct RFC 5322 generation by tagging white space
as folding white space only when folding is allowed in the non-obsolete rule
sets.  Actually, the parser is even more generous when accepting input than RFC
5322 mandates, following the spirit of Postel's Law, which RFC 5322 encourages.
Where possible deviations from the standard are annotated on the 'defects'
attribute of tokens that deviate.

The general structure of the parser follows RFC 5322, and uses its terminology
where there is a direct correspondence.  Where the implementation requires a
somewhat different structure than that used by the formal grammar, new terms
that mimic the closest existing terms are used.  Thus, it really helps to have
a copy of RFC 5322 handy when studying this code.

Input to the parser is a string that has already been unfolded according to
RFC 5322 rules.  According to the RFC this unfolding is the very first step, and
this parser leaves the unfolding step to a higher level message parser, which
will have already detected the line breaks that need unfolding while
determining the beginning and end of each header.

The output of the parser is a TokenList object, which is a list subclass.  A
TokenList is a recursive data structure.  The terminal nodes of the structure
are Terminal objects, which are subclasses of str.  These do not correspond
directly to terminal objects in the formal grammar, but are instead more
practical higher level combinations of true terminals.

All TokenList and Terminal objects have a 'value' attribute, which produces the
semantically meaningful value of that part of the parse subtree.  The value of
all whitespace tokens (no matter how many sub-tokens they may contain) is a
single space, as per the RFC rules.  This includes 'CFWS', which is herein
included in the general class of whitespace tokens.  There is one exception to
the rule that whitespace tokens are collapsed into single spaces in values: in
the value of a 'bare-quoted-string' (a quoted-string with no leading or
trailing whitespace), any whitespace that appeared between the quotation marks
is preserved in the returned value.  Note that in all Terminal strings quoted
pairs are turned into their unquoted values.

All TokenList and Terminal objects also have a string value, which attempts to
be a "canonical" representation of the RFC-compliant form of the substring that
produced the parsed subtree, including minimal use of quoted pair quoting.
Whitespace runs are not collapsed.

Comment tokens also have a 'content' attribute providing the string found
between the parens (including any nested comments) with whitespace preserved.

All TokenList and Terminal objects have a 'defects' attribute which is a
possibly empty list all of the defects found while creating the token.  Defects
may appear on any token in the tree, and a composite list of all defects in the
subtree is available through the 'all_defects' attribute of any node.  (For
Terminal notes x.defects == x.all_defects.)

Each object in a parse tree is called a 'token', and each has a 'token_type'
attribute that gives the name from the RFC 5322 grammar that it represents.
Not all RFC 5322 nodes are produced, and there is one non-RFC 5322 node that
may be produced: 'ptext'.  A 'ptext' is a string of printable ascii characters.
It is returned in place of lists of (ctext/quoted-pair) and
(qtext/quoted-pair).

       obs-NO-WS-CTL is control characters except WSP/CR/LF.

    So, basically, we have printable runs, plus control characters or nulls in
    the obsolete syntax, separated by whitespace.  Since RFC 2047 uses the
    obsolete syntax in its specification, but requires whitespace on either
    side of the encoded words, I can see no reason to need to separate the
    non-printable-non-whitespace from the printable runs if they occur, so we
    parse this into xtext tokens separated by WSP tokens.

    Because an 'unstructured' value must by definition constitute the entire
    value, this 'get' routine does not return a remaining value, only the
    parsed TokenList.

    Either atom or quoted-string may start with CFWS.  We have to peel off this

    the leading CFWS, if any, into the parsed sub-token.

    If neither an atom or a quoted-string is found before the next special, a
    HeaderParseError is raised.

    The token returned is either an Atom or a QuotedString, as appropriate.
    This means the 'word' level of the formal grammar is not represented in the
    parse tree; this is because having that extra layer when manipulating the
    parse tree is more confusing than it is helpful.

    That BNF is meant to indicate this routine should only be called after
    finding and handling the leading ';'.  There is no corresponding rule in
    the formal RFC grammar, but it is more convenient for us for the set of
    parameters to be treated as its own TokenList.

    This is 'parse' routine because it consumes the remaining value, but it
    would never be called to parse a full header.  Instead it is called to
    parse everything after the non-parameter value of a specific MIME header.

    To understand what this class does, it helps to have a copy of RFC 2822 in
    front of you.

    Note: this class interface is deprecated and may be removed in the future.
    Use email.utils.AddressList instead.

    This class is useless unless subclassed.  A subclass should define
    class attributes with defaults for any values that are to be
    managed by the Policy object.  The constructor will then allow
    non-default values to be set for these attributes at instance
    creation time.  The instance will be callable, taking these same
    attributes keyword arguments, and returning a new instance
    identical to the called instance except for those values changed
    by the keyword arguments.  Instances may be added, yielding new
    instances with any non-default values from the right hand
    operand overriding those in the left hand operand.  That is,

        A + B == A(<non-default values of B>)

    The repr of an instance can be used to reconstruct the object
    if and only if the repr of the values can be used to reconstruct
    those values.

jdd��ZdS)raI	Controls for how messages are interpreted and formatted.

    Most of the classes and many of the methods in the email package accept
    Policy objects as parameters.  A Policy object contains a set of values and
    functions that control how input is interpreted and how output is rendered.
    For example, the parameter 'raise_on_defect' controls whether or not an RFC
    violation results in an error being raised or not, while 'max_line_length'
    controls the maximum length of output lines when a Message is serialized.

    Any valid attribute may be overridden when a Policy is created by passing
    it as a keyword argument to the constructor.  Policy objects are immutable,
    but a new Policy object can be created with only certain values changed by
    calling the Policy instance with keyword arguments.  Policy objects can
    also be added, producing a new Policy object in which the non-default
    attributes set in the right hand operand overwrite those specified in the
    left operand.

    Settable attributes:

    raise_on_defect     -- If true, then defects should be raised as errors.
                           Default: False.

    linesep             -- string containing the value to use as separation
                           between output lines.  Default '\n'.

    cte_type            -- Type of allowed content transfer encodings

                           7bit  -- ASCII only
                           8bit  -- Content-Transfer-Encoding: 8bit is allowed

                           Default: 8bit.  Also controls the disposition of
                           (RFC invalid) binary data in headers; see the
                           documentation of the binary_fold method.

    max_line_length     -- maximum length of lines, excluding 'linesep',
                           during serialization.  None or 0 means no line
                           wrapping is done.  Default is 78.

    mangle_from_        -- a flag that, when True escapes From_ lines in the
                           body of the message by putting a `>' in front of
                           them. This is used when the message is being
                           serialized by a generator. Default: True.

    message_factory     -- the class to use to create new message objects.
                           If the value is None, the default is Message.

|�|�||�dS)aZBased on policy, either raise defect or call register_defect.

            handle_defect(obj, defect)

        defect should be a Defect subclass, but in any case must be an
        Exception subclass.  obj is the object on which the defect should be
        registered if it is not raised.  If the raise_on_defect is True, the
        defect is raised as an error, otherwise the object and the defect are
        passed to register_defect.

        This method is intended to be called by parsers that discover defects.
        The email package parsers always call it with Defect instances.

        N)�raise_on_defect�register_defect�r�obj�defectrrr�
handle_defect�szPolicy.handle_defectcCs|j�|�dS)a�Record 'defect' on 'obj'.

        Called by handle_defect if raise_on_defect is False.  This method is
        part of the Policy API so that Policy subclasses can implement custom
        defect handling.  The default implementation calls the append method of
        the defects attribute of obj.  The objects used by the email package by
        default that get passed to this method will always have a defects
        attribute with an append method.

        N)�defects�appendrBrrrrA�szPolicy.register_defectcCsdS)a[Return the maximum allowed number of headers named 'name'.

        Called when a header is added to a Message object.  If the returned
        value is not 0 or None, and there are already a number of headers with
        the name 'name' equal to the value returned, a ValueError is raised.

        Because the default behavior of Message's __setitem__ is to append the
        value to the list of headers, it is easy to create duplicate headers
        without realizing it.  This method allows certain headers to be limited
        in the number of instances of that header that may be added to a
        Message programmatically.  (The limit is not observed by the parser,
        which will faithfully produce as many headers as exist in the message
        being parsed.)

        The default implementation returns None for all header names.

dd�ZeZeZdS)a�Base64 content transfer encoding per RFCs 2045-2047.

This module handles the content transfer encoding method defined in RFC 2045
to encode arbitrary 8-bit data using the three 8-bit bytes in four 7-bit
characters encoding known as Base64.

It is used in the MIME standards for email to attach images, audio, and text
using some 8-bit character sets to messages.

This module provides an interface to encode and decode both headers and bodies
with Base64 encoding.

RFC 2045 defines a method for including character set information in an
`encoded-word' in a header.  This method is commonly used for 8-bit real names
in To:, From:, Cc:, etc. fields, as well as Subject: lines.

This module does not do the line wrapping or end-of-line character conversion
necessary for proper internationalized headers; it only does dumb encoding and
decoding.  To deal with the various line wrapping issues, use the email.header
module.

cCs"|tkrtd��|||ft|<dS)a>Add character set properties to the global registry.

    charset is the input character set, and must be the canonical name of a
    character set.

    Optional header_enc and body_enc is either Charset.QP for
    quoted-printable, Charset.BASE64 for base64 encoding, Charset.SHORTEST for
    the shortest of qp or base64 encoding, or None for no encoding.  SHORTEST
    is only valid for header_enc.  It describes how message headers and
    message bodies in the input charset are to be encoded.  Default is no
    encoding.

    Optional output_charset is the character set that the output should be
    in.  Conversions will proceed from input charset, to Unicode, to the
    output charset when the method Charset.convert() is called.  The default
    is to output in the same character set as the input.

    Both input_charset and output_charset must have Unicode codec entries in
    the module's charset-to-codec mapping; use add_codec(charset, codecname)
    to add codecs the module does not know about.  See the codecs module's
    documentation for more information.

dS)ra@	Map character sets to their email properties.

    This class provides information about the requirements imposed on email
    for a specific character set.  It also provides convenience routines for
    converting between character sets, given the availability of the
    applicable codecs.  Given a character set, it will do its best to provide
    information on how to use that character set in an email in an
    RFC-compliant way.

    Certain character sets must be encoded with quoted-printable or base64
    when used in email headers or bodies.  Certain character sets must be
    converted outright, and are not allowed in email.  Instances of this
    module expose the following information about a character set:

    input_charset: The initial character set specified.  Common aliases
                   are converted to their `official' email names (e.g. latin_1
                   is converted to iso-8859-1).  Defaults to 7-bit us-ascii.

    header_encoding: If the character set must be encoded before it can be
                     used in an email header, this attribute will be set to
                     Charset.QP (for quoted-printable), Charset.BASE64 (for
                     base64 encoding), or Charset.SHORTEST for the shortest of
                     QP or BASE64 encoding.  Otherwise, it will be None.

    body_encoding: Same as header_encoding, but describes the encoding for the
                   mail message's body, which indeed may be different than the
                   header encoding.  Charset.SHORTEST is not allowed for
                   body_encoding.

    output_charset: Some character sets must be converted before they can be
                    used in email headers or bodies.  If the input_charset is
                    one of them, this attribute will contain the name of the
                    charset output will be converted to.  Otherwise, it will
                    be None.

    input_codec: The name of the Python codec used to convert the
                 input_charset to Unicode.  If no conversion codec is
                 necessary, this attribute will be None.

    output_codec: The name of the Python codec used to convert Unicode
                  to the output_charset.  If no conversion codec is necessary,
                  this attribute will have the same value as the input_codec.

        This is either the string `quoted-printable' or `base64' depending on
        the encoding used, or it is a function in which case you should call
        the function with a single argument, the Message object being
        encoded.  The function should then set the Content-Transfer-Encoding
        header itself to whatever is appropriate.

        Returns "quoted-printable" if self.body_encoding is QP.
        Returns "base64" if self.body_encoding is BASE64.

            not count the RFC 2047 chrome.  These line lengths are only a

The feed parser implements an interface for incrementally parsing an email
message, line by line.  This has advantages for certain applications, such as
those reading email messages off a socket.

FeedParser.feed() is the primary interface for pushing new data into the
parser.  It returns when there's nothing more it can do with the available
data.  When you have no more data to push into the parser, call .close().
This completes the parsing and returns the root message object.

The other advantage of this parser is that it will never raise a parsing
exception.  Instead, when it finds something unexpected, it adds a 'defect' to
the current message.  Defects are just instances that live on the message
object's .defects attribute.

    You can also push and pop line-matching predicates onto a stack.  When the
    current predicate matches the current line, a false EOF response
    (i.e. empty string) is returned instead.  This lets the parser adhere to a
    simple abstraction -- it parses until EOF closes the current message.

        outfp is the output file-like object for writing the message to.  It
        must have a write() method.

        Optional mangle_from_ is a flag that, when True (the default if policy
        is not set), escapes From_ lines in the body of the message by putting
        a `>' in front of them.

        Optional maxheaderlen specifies the longest length for a non-continued
        header.  When a header line is longer (in characters, with tabs
        expanded to 8 spaces) than maxheaderlen, the header will split as
        defined in the Header class.  Set maxheaderlen to zero to disable
        header wrapping.  The default is 78, as recommended (but not required)
        by RFC 2822.

        The policy keyword specifies a policy object that controls a number of
        aspects of the generator's operation.  If no policy is specified,
        the policy associated with the Message object passed to the
        flatten method is used.

        unixfrom is a flag that forces the printing of a Unix From_ delimiter
        before the first object in the message tree.  If the original message
        has no From_ delimiter, a `standard' one is crafted.  By default, this
        is False to inhibit the printing of any From_ delimiter.

        Note that for subobjects, no From_ line is printed.

        linesep specifies the characters used to indicate a new line in
        the output.  The default value is determined by the policy specified
        when the Generator instance was created or, if none was specified,
        from the policy associated with the msg.

    Functionally identical to the base Generator except that the output is
    bytes and not string.  When surrogates were used in the input to encode
    bytes, these are decoded back to bytes for output.  If the policy has

    non-ASCII bytes are properly content transfer encoded, using the charset
    unknown-8bit.

    decode_header() takes a header value string and returns a sequence of

    This function takes one of those sequence of pairs and returns a Header

        Optional s is the initial header value.  If None, the initial header
        value is not set.  You can later append to the header with .append()
        method calls.  s may be a byte string or a Unicode string, but see the
        .append() documentation for semantics.

        Optional charset serves two purposes: it has the same meaning as the
        charset argument to the .append() method.  It also sets the default
        character set for all subsequent .append() calls that omit the charset
        argument.  If charset is not provided in the constructor, the us-ascii
        charset is used both as s's initial charset and as the default for
        subsequent .append() calls.

        The maximum line length can be specified explicitly via maxlinelen. For

        header which isn't included in s, e.g. `Subject') pass in the name of
        the field in header_name.  The default maxlinelen is 78 as recommended
        by RFC 2822.

        continuation_ws must be RFC 2822 compliant folding whitespace (usually
        either a space or a hard tab) which will be prepended to continuation
        lines.

        errors is passed through to the .append() call.

}YnX|j�||f�dS)a.Append a string to the MIME header.

        Optional charset, if given, should be a Charset instance or the name
        of a character set (which will be converted to a Charset instance).  A
        value of None (the default) means that the charset given in the
        constructor is used.

        s may be a byte string or a Unicode string.  If it is a byte string
        (i.e. isinstance(s, str) is false), then charset is the encoding of
        that byte string, and a UnicodeError will be raised if the string
        cannot be decoded with that charset.  If s is a Unicode string, then
        charset is a hint specifying the character set of the characters in
        the string.  In either case, when producing an RFC 2822 compliant
        header using RFC 2047 rules, the string will be encoded using the
        output codec of the charset.  If the string cannot be encoded to the
        output codec, a UnicodeError will be raised.

        Optional `errors' is passed as the errors argument to the decode
        call if s is a byte string.

�|���|S)a�Encode a message header into an RFC-compliant format.

        There are many issues involved in converting a given string for use in
        an email header.  Only certain character sets are readable in most
        email clients, and as header strings can only contain a subset of
        7-bit ASCII, care must be taken to properly convert and encode (with
        Base64 or quoted-printable) header strings.  In addition, there is a
        75-character length limit on any given encoded header field, so
        line-wrapping must be performed, even with double-byte character sets.

        Optional maxlinelen specifies the maximum length of each generated
        line, exclusive of the linesep string.  Individual lines may be longer
        than maxlinelen if a folding point cannot be found.  The first line
        will be shorter by the length of the header name plus ": " if a header
        name was specified at Header construction time.  The default value for
        maxlinelen is determined at header construction time.

        Optional splitchars is a string containing characters which should be
        given extra weight by the splitting algorithm during normal header
        wrapping.  This is in very rough support of RFC 2822's `higher level
        syntactic breaks':  split points preceded by a splitchar are preferred
        during line splitting, with the characters preferred in the order in
        which they appear in the string.  Space and tab may be included in the
        string to indicate whether preference should be given to one over the
        other as a split point when other split chars do not appear in the line
        being split.  Splitchars does not affect RFC 2047 encoded lines.

        Optional linesep is a string to be used to separate the lines of
        the value.  The default value is the most useful for typical
        Python applications, but it can be set to \r\n to produce RFC-compliant
        line separators when needed.

The implementation is designed to flexibly follow RFC5322 rules.

Eventually HeaderRegistry will be a public API, but it isn't yet,
and will probably change some before that happens.

        An address can have a 'display_name', a 'username', and a 'domain'.  In
        addition to specifying the username and domain separately, they may be
        specified together by using the addr_spec keyword *instead of* the
        username and domain keywords.  If an addr_spec string is specified it
        must be properly quoted according to RFC 5322 rules; an error will be
        raised if it is not.

        An Address object has display_name, username, domain, and addr_spec
        attributes, all of which are read-only.  The addr_spec and the string
        value of the object are both quoted according to RFC5322 rules, but
        without any Content Transfer Encoding.

        An address group consists of a display_name followed by colon and a
        list of addresses (see Address) terminated by a semi-colon.  The Group
        is created by specifying a display_name and a possibly empty list of
        Address objects.  A Group can also be used to represent a single
        address that is not in a group, which is convenient when manipulating
        lists that are a combination of Groups and individual Addresses.  In
        this case the display_name should be set to None.  In particular, the
        string representation of a Group whose display_name is None is the same
        as the Address object, if there is one and only one Address object in
        the addresses list.

BaseHeadera|Base class for message headers.

    Implements generic behavior and provides tools for subclasses.

    A subclass must define a classmethod named 'parse' that takes an unfolded
    value string and a dictionary as its arguments.  The dictionary will
    contain one key, 'defects', initialized to an empty list.  After the call
    the dictionary must contain two additional keys: parse_tree, set to the
    parse tree obtained from parsing the header, and 'decoded', set to the
    string value of the idealized representation of the data from the value.
    (That is, encoded words are decoded, and values that have canonical
    representations are so represented.)

    The defects key is intended to collect parsing defects, which the message
    parser will subsequently dispose of as appropriate.  The parser should not,
    insofar as practical, raise any errors.  Defects should be added to the
    list instead.  The standard header parsers register defects for RFC
    compliance issues, for obsolete RFC syntax, and for unrecoverable parsing
    errors.

    The parse method may add additional keys to the dictionary.  In this case
    the subclass must define an 'init' method, which will be passed the
    dictionary as its keyword arguments.  The method should use (usually by
    setting them as the value of similarly named attributes) and remove all the
    extra keys added by its parse method, and then use super to call its parent
    class with the remaining arguments and keywords.

    The subclass should also make sure that a 'max_count' attribute is defined
    that is either None or 1. XXX: need to better define this API.

        The parsed representation of the header is folded according to
        RFC5322 rules, as modified by the policy.  If the parse tree
        contains surrogateescaped bytes, the bytes are CTE encoded using
        the charset 'unknown-8bit".

        Any non-ASCII characters in the parse tree are CTE encoded using
        charset utf-8. XXX: make this a policy setting.

        The returned value is an ASCII-only string possibly containing linesep
        characters, and ending with a linesep character.  The string includes
        the header name and the ': ' separator.

DateHeadera�Header whose value consists of a single timestamp.

    Provides an additional attribute, datetime, which is either an aware
    datetime using a timezone, or a naive datetime if the timezone
    in the input string is -0000.  Also accepts a datetime as input.
    The 'value' attribute is the normalized form of the timestamp,
    which means it is the output of format_datetime on the datetime.

    A message object is defined as something that has a bunch of RFC 2822
    headers and a payload.  It may optionally have an envelope header
    (a.k.a. Unix-From or From_ header).  If the message is a container (i.e. a
    multipart or a message/rfc822), then the payload is a list of Message
    objects, otherwise it is a string.

    Message objects implement part of the `mapping' interface, which assumes
    there is exactly one occurrence of the header per message.  Some headers
    do in fact appear multiple times (e.g. Received) and for those headers,
    you must use the explicit API to set or get all the headers.  Not all of
    the mapping methods are implemented.

        Optional 'unixfrom', when true, means include the Unix From_ envelope
        header.  For backward compatibility reasons, if maxheaderlen is
        not specified it defaults to 0, so you must override it explicitly
        if you want a different maxheaderlen.  'policy' is passed to the
        Generator instance used to serialize the message; if it is not
        specified the policy associated with the message instance is used.

        If the message object contains binary data that is not encoded
        according to RFC standards, the non-compliant data will be replaced by
        unicode "unknown character" code points.

        The payload will either be a list object or a string.  If you mutate
        the list object, you modify the message's payload in place.  Optional
        i returns that index into the payload.

        Optional decode is a flag indicating whether the payload should be
        decoded or not, according to the Content-Transfer-Encoding header
        (default is False).

        When True and the message is not a multipart, the payload will be
        decoded if this header's value is `quoted-printable' or `base64'.  If
        some other encoding is used, or the header is missing, or if the
        payload has bogus data (i.e. bogus base64 or uuencoded data), the
        payload is returned as-is.

        If the message is a multipart and the decode flag is True, then None

        Optional failobj is the object to return if there is no Content-Type
        header, or the Content-Type header has no such parameter.  Optional
        header is the header to search instead of Content-Type.

        Parameter keys are always compared case insensitively.  The return
        value can either be a string, or a 3-tuple if the parameter was RFC
        2231 encoded.  When it's a 3-tuple, the elements of the value are of
        the form (CHARSET, LANGUAGE, VALUE).  Note that both CHARSET and
        LANGUAGE can be None, in which case you should consider VALUE to be
        encoded in the us-ascii charset.  You can usually ignore LANGUAGE.
        The parameter value (either the returned string, or the VALUE item in
        the 3-tuple) is always unquoted, unless unquote is set to False.

        If your application doesn't care whether the parameter was RFC 2231
        encoded, it can turn the return value into a string as follows:

            rawparam = msg.get_param('foo')
            param = email.utils.collapse_rfc2231_value(rawparam)

    PROVISIONAL

    The API extensions enabled by this policy are currently provisional.
    Refer to the documentation for details.

    This policy adds new header parsing and folding algorithms.  Instead of
    simple strings, headers are custom objects with custom attributes
    depending on the type of the field.  The folding algorithm fully
    implements RFCs 2047 and 5322.

    In addition to the settable attributes listed above that apply to
    all Policies, this policy adds the following additional attributes:

    utf8                -- if False (the default) message headers will be
                           serialized as ASCII, using encoded words to encode
                           any non-ASCII characters in the source strings.  If
                           True, the message headers will be serialized using
                           utf8 and will not contain encoded words (see RFC
                           6532 for more on this serialization format).

    refold_source       -- if the value for a header in the Message object
                           came from the parsing of some source, this attribute
                           indicates whether or not a generator should refold
                           that value when transforming the message back into
                           stream form.  The possible values are:

                           none  -- all source values use original folding
                           long  -- source values that have any line that is
                                    longer than max_line_length will be
                                    refolded
                           all  -- all values are refolded.

                           The default is 'long'.

    header_factory      -- a callable that takes two arguments, 'name' and
                           'value', where 'name' is a header field name and
                           'value' is an unfolded header field value, and
                           returns a string-like object that represents that
                           header.  A default header_factory is provided that
                           understands some of the RFC5322 header field types.
                           (Currently address fields and date fields have
                           special treatment, while all other fields are
                           treated as unstructured.  This list will be
                           completed before the extension is marked stable.)

    content_manager     -- an object with at least two methods: get_content
                           and set_content.  When the get_content or
                           set_content method of a Message object is called,
                           it calls the corresponding method of this object,
                           passing it the message object as its first argument,
                           and any arguments or keywords that were passed to
                           it as additional arguments.  The default
                           content_manager is
                           :data:`~email.contentmanager.raw_data_manager`.

        Header folding is controlled by the refold_source policy setting.  A
        value is considered to be a 'source value' if and only if it does not
        have a 'name' attribute (having a 'name' attribute means it is a header
        object of some sort).  If a source value needs to be refolded according
        to the policy, it is converted into a custom header object by passing
        the name and the value with any linesep characters removed to the
        header_factory method.  Folding of a custom header object is done by
        calling its fold method with the current policy.

        Source values are split into lines using splitlines.  If the value is
        not to be refolded, the lines are rejoined using the linesep from the
        policy and returned.  The exception is lines containing non-ascii
        binary data.  In that case the value is refolded regardless of the
        refold_source setting, which causes the binary data to be CTE encoded
        using the unknown-8bit charset.

        The same as fold if cte_type is 7bit, except that the returned value is
        bytes.

        If cte_type is 8bit, non-ASCII binary data is converted back into
        bytes.  Headers with binary data are not refolded, regardless of the
        refold_header setting, since there is no way to know whether the binary
        data consists of single byte characters or multibyte characters.

        If utf8 is true, headers are encoded to utf8, otherwise to ascii with
        non-ASCII unicode rendered as encoded words.

This module handles the content transfer encoding method defined in RFC 2045
to encode US ASCII-like 8-bit data called `quoted-printable'.  It is used to
safely encode text that is in a character set similar to the 7-bit US ASCII
character set, but that includes some 8-bit characters that are normally not
allowed in email bodies or headers.

Quoted-printable is very space-inefficient for encoding binary files; use the
email.base64mime module for that instead.

This module provides an interface to encode and decode both headers and bodies
with quoted-printable encoding.

RFC 2045 defines a method for including character set information in an
`encoded-word' in a header.  This method is commonly used for 8-bit real names
in To:/From:/Cc: etc. fields, as well as Subject: lines.

This module does not do the line wrapping or end-of-line character
conversion necessary for proper internationalized headers; it only
does dumb encoding and decoding.  To deal with the various line
wrapping issues, use the email.header module.

    Each line of encoded text will end with eol, which defaults to "\n".  Set
    this to "\r\n" if you will be using the result of this function directly
    in an email.

    Each line will be wrapped at, at most, maxlinelen characters before the
    eol string (maxlinelen defaults to 76 characters, the maximum value
    permitted by RFC 2045).  Long lines will have the 'soft line break'
    quoted-printable character "=" appended to them, so the decoded text will
    be identical to the original text.

    The minimum maxlinelen is 4 to have room for a quoted character ("=XX")
    followed by a soft line break.  Smaller values will generate a
    ValueError.

    If called without arguments, return current time.  Otherwise *dt*
    argument should be a datetime instance, and it is converted to the
    local time zone according to the system time zone database.  If *dt* is
    naive (that is, dt.tzinfo is None), it is assumed to be in local time.
    In this case, a positive or zero value for *isdst* causes localtime to
    presume initially that summer time (for example, Daylight Saving Time)
    is or is not (respectively) in effect for the specified time.  A
    negative value for *isdst* causes the localtime() function to attempt
    to divine whether summer time is in effect for the specified time.

HTTP/1.1 client library

<intro stuff goes here>
<other stuff, too>

HTTPConnection goes through a number of "states", which define when a client
may legally make another request or fetch the response for a particular
request. This diagram details these state transitions:

    (null)
      |
      | HTTPConnection()
      v
    Idle
      |
      | putrequest()
      v
    Request-started
      |
      | ( putheader() )*  endheaders()
      v
    Request-sent
      |\_____________________________
      |                              | getresponse() raises
      | response = getresponse()     | ConnectionError
      v                              v
    Unread-response                Idle
    [Response-headers-read]
      |\____________________
      |                     |
      | response.read()     | putrequest()
      v                     v
    Idle                  Req-started-unread-response
                     ______/|
                   /        |
   response.read() |        | ( putheader() )*  endheaders()
                   v        v
       Request-started    Req-sent-unread-response
                            |
                            | response.read()
                            v
                          Request-sent

This diagram presents the following rules:
  -- a second request may not be started until {response-headers-read}
  -- a response [object] cannot be retrieved until {request-sent}
  -- there is no differentiation between an unread response body and a
     partially read response body

Note: this enforcement is applied by the HTTPConnection class. The
      HTTPResponse class does not enforce this state machine, which
      implies sophisticated clients may accelerate the request/response
      pipeline. Caution should be taken, though: accelerating the states
      beyond the above pattern may imply knowledge of the server's
      connection-close behavior for certain requests. For example, it
      is impossible to tell whether the server will close the connection
      UNTIL the response headers have been read; this means that further
      requests cannot be placed into the pipeline until it is known that
      the server will NOT be closing the connection.

Logical State                  __state            __response
-------------                  -------            ----------
Idle                           _CS_IDLE           None
Request-started                _CS_REQ_STARTED    None
Request-sent                   _CS_REQ_SENT       None
Unread-response                _CS_IDLE           <response_class>

    email Parser wants to see strings rather than bytes.
    But a TextIOWrapper around self.rfile would buffer too many bytes
    from the stream, bytes which we later need to read as bytes.
    So we read the correct bytes here, as bytes, for email Parser
    to parse.

        meta-information associated with the URL.

        When the method is HTTP, these headers are those returned by
        the server at the head of the retrieved HTML page (including
        Content-Length and Content-Type).

        When the method is FTP, a Content-Length header will be
        present if (as is now usual) the server passed back a file
        length in response to the FTP retrieval request. A
        Content-Type header will be present if the MIME type can be
        guessed.

        When the method is local-file, returned headers will include
        a Date representing the file's last-modified time, a
        Content-Length giving file size, and a Content-Type
        containing a guess at the file's type. See also the
        description of the mimetools module.

        In some cases, the HTTP server redirects a client to another
        URL. The urlopen() function handles this transparently, but in
        some cases the caller needs to know which URL the client was
        redirected to. The geturl() method can be used to get at this
        redirected URL.

|j��dS)aDSet up host and port for HTTP CONNECT tunnelling.

        In a connection that uses HTTP CONNECT tunneling, the host passed to the
        constructor is used as a proxy server that relays all communication to
        the endpoint passed to `set_tunnel`. This done by sending an HTTP
        CONNECT request to the proxy server when the connection is established.

        This method must be called before the HTTP connection has been
        established.

        The headers argument should be a mapping of extra HTTP headers to send
        with the CONNECT request.

S)wa�HTTP cookie handling for web clients.

This module has (now fairly distant) origins in Gisle Aas' Perl module
HTTP::Cookies, from the libwww-perl library.

Docstrings, comments and debug strings in this code refer to the
attributes of the HTTP cookie system as cookie-attributes, to distinguish
them clearly from Python attributes.

Class diagram (note that BSDDBCookieJar and the MSIE* classes are not
distributed with the Python standard library, but are available from
http://wwwsearch.sf.net/):

a�Returns time in seconds since epoch of time represented by a string.

    Return value is an integer.

    None is returned if the format of str is unrecognized, the time is outside
    the representable range, or the timezone string is not recognized.  If the
    string contains no timezone, UTC is assumed.

    The timezone in the string may be numerical (like "-0800" or "+0100") or a
    string timezone (like "UTC", "GMT", "BST" or "EST").  Currently, only the
    timezone strings equivalent to UTC (zero offset) are known to the function.

    The function loosely parses the following formats:

    Wed, 09 Feb 1994 22:23:32 GMT       -- HTTP format
    Tuesday, 08-Feb-94 14:15:29 GMT     -- old rfc850 HTTP format
    Tuesday, 08-Feb-1994 14:15:29 GMT   -- broken rfc850 HTTP format
    09 Feb 1994 22:23:32 GMT            -- HTTP format (no weekday)

    The function knows how to deal with ",", ";" and "=" as well as quoted
    values after "=".  A list of space separated tokens are parsed as if they
    were separated by ";".

    If the header_values passed as argument contains multiple values, then they
    are treated as if they were a single value separated by comma ",".

    This means that this function is useful for parsing header fields that
    follow this syntax (BNF as from the HTTP/1.1 specification, but we relax
    the requirement for tokens).

      headers           = #header
      header            = (token | parameter) *( [";"] (token | parameter))

      token             = 1*<any CHAR except CTLs or separators>
      separators        = "(" | ")" | "<" | ">" | "@"
                        | "," | ";" | ":" | "\" | <">
                        | "/" | "[" | "]" | "?" | "="
                        | "{" | "}" | SP | HT

      quoted-string     = ( <"> *(qdtext | quoted-pair ) <"> )
      qdtext            = <any TEXT except <">>
      quoted-pair       = "\" CHAR

      parameter         = attribute "=" value
      attribute         = token
      value             = token | quoted-string

    Each header is represented by a list of key/value pairs.  The value for a
    simple token (not part of a parameter) is None.  Syntactically incorrect
    headers will not necessarily be parsed as you would want.

    This is easier to describe with some examples:

    >>> split_header_words(['foo="bar"; port="80,81"; discard, bar=baz'])
    [[('foo', 'bar'), ('port', '80,81'), ('discard', None)], [('bar', 'baz')]]
    >>> split_header_words(['text/html; charset="iso-8859-1"'])
    [[('text/html', None), ('charset', 'iso-8859-1')]]
    >>> split_header_words([r'Basic realm="\"foo\bar\""'])
    [[('Basic', None), ('realm', '"foobar"')]]

�|�|�q|S)a5Ad-hoc parser for Netscape protocol cookie-attributes.

    The old Netscape cookie format for Set-Cookie can for instance contain
    an unquoted "," in the expires field, so we have to use this ad-hoc
    parser instead of split_header_words.

    XXX This may not make the best possible effort to parse all the crap
    that Netscape Cookie headers contain.  Ronald Tschalar's HTTPClient
    parser is probably better, so could do worse than following that if
    this ever gives any trouble.

    Currently, this is also used for parsing RFC 2109 cookies.

    A and B may be host domain names or IP addresses.

    RFC 2965, section 1:

    Host names can be specified either as an IP address or a HDN string.
    Sometimes we compare one host name with another.  (Such comparisons SHALL
    be case-insensitive.)  Host A's name domain-matches host B's if

         *  their host name strings string-compare equal; or

         * A is a HDN string and has the form NB, where N is a non-empty
            name string, B has the form .B', and B' is a HDN string.  (So,
            x.y.com domain-matches .Y.com but not Y.com.)

    Note that domain-match is not a commutative operation: a.b.c.com
    domain-matches .c.com, but not the reverse.

dS)ra�HTTP Cookie.

    This class represents both Netscape and RFC 2965 cookies.

    This is deliberately a very simple class.  It just holds attributes.  It's
    possible to construct Cookie instances that don't comply with the cookie
    standards.  CookieJar.make_cookies is the factory function for Cookie
    objects -- it deals with cookie parsing, supplying defaults, and
    normalising to the representation used in this class.  CookiePolicy is
    responsible for checking them to see whether they should be accepted from
    and returned to the server.

    Note that the port may be present in the headers, but unspecified ("Port"
    rather than"Port=80", for example); if this is the case, port is None.

    WARNING: you may want to backup your browser's cookies file if you use
    this class to save cookies.  I *think* it works, but there have been
    bugs in the past!

    This class differs from CookieJar only in the format it uses to save and
    load cookies to and from a file.  This class uses the Mozilla/Netscape
    `cookies.txt' format.  lynx uses this file format, too.

    Don't expect cookies saved while the browser is running to be noticed by
    the browser (in fact, Mozilla on unix will overwrite your saved cookies if
    you change them on disk while it's running; on Windows, you probably can't
    save at all while the browser is running).

    Note that the Mozilla/Netscape format will downgrade RFC2965 cookies to
    Netscape cookies on saving.

    In particular, the cookie version and port number information is lost,
    together with information about whether or not Path, Port and Discard were
    specified by the Set-Cookie2 (or Set-Cookie) header, and whether or not the
    domain as set in the HTTP header started with a dot (yes, I'm aware some
    domains in Netscape files start with a dot and some don't -- trust me, you
    really don't want to know any more about this).

    Note that though Mozilla and Netscape use the same format, they use
    slightly different headers.  The class saves cookies using the Netscape
    header by default (Mozilla can cope with that).

Here's a sample session to show how to use this module.
At the moment, this is the only documentation.

The Basics
----------

Importing is easy...

   >>> from http import cookies

Most of the time you start by creating a cookie.

   >>> C = cookies.SimpleCookie()

Once you've created your Cookie, you can add values just as if it were
a dictionary.

   >>> C = cookies.SimpleCookie()
   >>> C["fig"] = "newton"
   >>> C["sugar"] = "wafer"
   >>> C.output()
   'Set-Cookie: fig=newton\r\nSet-Cookie: sugar=wafer'

Notice that the printable representation of a Cookie is the
appropriate format for a Set-Cookie: header.  This is the
default behavior.  You can change the header and printed
attributes by using the .output() function

   >>> C = cookies.SimpleCookie()
   >>> C["rocky"] = "road"
   >>> C["rocky"]["path"] = "/cookie"
   >>> print(C.output(header="Cookie:"))
   Cookie: rocky=road; Path=/cookie
   >>> print(C.output(attrs=[], header="Cookie:"))
   Cookie: rocky=road

The load() method of a Cookie extracts cookies from a string.  In a
CGI script, you would use this method to extract the cookies from the
HTTP_COOKIE environment variable.

   >>> C = cookies.SimpleCookie()
   >>> C.load("chips=ahoy; vienna=finger")
   >>> C.output()
   'Set-Cookie: chips=ahoy\r\nSet-Cookie: vienna=finger'

The load() method is darn-tootin smart about identifying cookies
within a string.  Escaped quotation marks, nested semicolons, and other
such trickeries do not confuse it.

   >>> C = cookies.SimpleCookie()
   >>> C.load('keebler="E=everybody; L=\\"Loves\\"; fudge=\\012;";')
   >>> print(C)
   Set-Cookie: keebler="E=everybody; L=\"Loves\"; fudge=\012;"

Each element of the Cookie also supports all of the RFC 2109
Cookie attributes.  Here's an example which sets the Path
attribute.

   >>> C = cookies.SimpleCookie()
   >>> C["oreo"] = "doublestuff"
   >>> C["oreo"]["path"] = "/"
   >>> print(C)
   Set-Cookie: oreo=doublestuff; Path=/

Each dictionary element has a 'value' attribute, which gives you
back the value associated with the key.

   >>> C = cookies.SimpleCookie()
   >>> C["twix"] = "none for you"
   >>> C["twix"].value
   'none for you'

The SimpleCookie expects that all values should be standard strings.
Just to be sure, SimpleCookie invokes the str() builtin to convert
the value to a string, when the values are set dictionary-style.

   >>> C = cookies.SimpleCookie()
   >>> C["number"] = 7
   >>> C["string"] = "seven"
   >>> C["number"].value
   '7'
   >>> C["string"].value
   'seven'
   >>> C.output()
   'Set-Cookie: number=7\r\nSet-Cookie: string=seven'

        It provides methods for creating and returning SharedMemory instances
        and for creating a list-like object (ShareableList) backed by shared

        that support synchronization across processes (i.e. multi-process-safe

    shared memory block.

    Every shared memory block is assigned a unique name.  This enables
    one process to create a shared memory block with a particular name
    so that a different process can attach to that same shared memory
    block using that same name.

    As a resource for sharing data across processes, shared memory blocks
    may outlive the original process that created them.  When one process
    no longer needs access to a shared memory block that might still be
    needed by other processes, the close() method should be called.
    When a shared memory block is no longer needed by any process, the
    unlink() method should be called to ensure proper cleanup.N���i�TFrc

        An attempt has been made to start a new process before the
        current process has finished its bootstrapping phase.

        This probably means that you are not using fork to start your
        child processes and you have forgotten to use the proper idiom
        in the main module:

            if __name__ == '__main__':
                freeze_support()
                ...

        The "freeze_support()" line can be omitted if the program
        is not going to be frozen to produce an executable.)r-rrL�RuntimeErrorrrrr�_check_not_importing_main�srVcCst�ttjt��jd�}tjdk	r2tj��|d<t	j

a�Split a pathname into drive/UNC sharepoint and relative path specifiers.
    Returns a 2-tuple (drive_or_unc, path); either part may be empty.

    If you assign
        result = splitdrive(p)
    It is always true that:
        result[0] + result[1] == p

    If the path contained a drive letter, drive_or_unc will contain everything
    up to and including the colon.  e.g. splitdrive("c:/dir") returns ("c:", "/dir")

    If the path contained a UNC path, the drive_or_unc will contain the host name
    and share up to but not including the fourth directory separator character.
    e.g. splitdrive("//host/computer/dir") returns ("//host/computer", "/dir")

    Paths cannot contain both a drive letter and a UNC path.

Package resource API
--------------------

A resource is a logical file contained within a package, or a logical
subdirectory thereof.  The package resource API expects resource names
to have their path parts separated with ``/``, *not* whatever the local
path separator is.  Do not use os.path operations to manipulate resource
names being passed into the API.

The package resource API is designed to work with normal filesystem packages,
.egg files, and unpacked .egg files.  It can also work in a limited way with
.zip files and with custom PEP 302 loaders that support the ``get_data()``
method.

    distutils.util.get_platform() normally reports the minimum version
    of Mac OS X that would be required to *use* extensions produced by
    distutils.  But what we want when checking compatibility is to know the
    version of Mac OS X that we are *running*.  To allow usage of packages that
    explicitly require a newer version of Mac OS X, we must also know the
    current version of the OS.

    If this condition occurs for any other platform with a version in its
    platform strings, this function should be extended accordingly.

        `requirements` must be a sequence of ``Requirement`` objects.  `env`,
        if supplied, should be an ``Environment`` instance.  If
        not supplied, it defaults to all distributions available within any
        entry or distribution in the working set.  `installer`, if supplied,
        will be invoked with each requirement that cannot be met by an
        already-installed distribution; it should return a ``Distribution`` or
        ``None``.

        Unless `replace_conflicting=True`, raises a VersionConflict exception
        if
        any requirements are found on the path that have the correct name but
        the wrong version.  Otherwise, if an `installer` is supplied it will be
        invoked to obtain the correct version of the requirement and activate
        it.

        `extras` is a list of the extras to be used with these requirements.
        This is important because extra requirements may look like `my_req;
        extra = "my_extra"`, which would otherwise be interpreted as a purely
        optional requirement.  Instead, we want to be able to assert that these
        requirements are truly required.

        Example usage::

            distributions, errors = working_set.find_plugins(
                Environment(plugin_dirlist)
            )
            # add plugins+libs to sys.path
            map(working_set.add, distributions)
            # display errors
            print('Could not load', errors)

        The `plugin_env` should be an ``Environment`` instance that contains
        only distributions that are in the project's "plugin directory" or
        directories. The `full_env`, if supplied, should be an ``Environment``
        contains all currently-available distributions.  If `full_env` is not
        supplied, one is created automatically from the ``WorkingSet`` this
        method is called on, which will typically mean that every directory on
        ``sys.path`` will be scanned for distributions.

        `installer` is a standard installer callback as used by the
        ``resolve()`` method. The `fallback` flag indicates whether we should
        attempt to resolve older versions of a plugin if the newest version
        cannot be resolved.

        This method returns a 2-tuple: (`distributions`, `error_info`), where
        `distributions` is a list of the distributions found in `plugin_env`
        that were loadable, along with any other distributions that are needed
        to resolve their dependencies.  `error_info` is a dictionary mapping
        unloadable plugin distributions to an exception instance describing the
        error that occurred. Usually this will be a ``DistributionNotFound`` or
        ``VersionConflict`` instance.

        `search_path` should be a sequence of ``sys.path`` items.  If not
        supplied, ``sys.path`` is used.

        `platform` is an optional string specifying the name of the platform
        that platform-specific distributions must be compatible with.  If
        unspecified, it defaults to the current platform.  `python` is an
        optional string naming the desired version of Python (e.g. ``'3.6'``);
        it defaults to the current version.

        You may explicitly set `platform` (and/or `python`) to ``None`` if you
        wish to map *all* distributions, not just those compatible with the

        This is where Mac header rewrites should be done; other platforms don't
        have anything special they should do.

        Resource providers should call this method ONLY after successfully
        extracting a compressed resource.  They must NOT call it on resources
        that are already in the filesystem.

        `tempname` is the current (temporary) name of the file, and `filename`
        is the name it will be renamed to by the caller after this routine
        returns.

        If you do not call this routine before any extractions take place, the

        is based on the ``PYTHON_EGG_CACHE`` environment variable, with various
        platform-specific fallbacks.  See that routine's documentation for more
        details.)

        Resources are extracted to subdirectories of this path based upon
        information given by the ``IResourceProvider``.  You may set this to a
        temporary directory, but then you must call ``cleanup_resources()`` to
        delete the extracted files when done.  There is no guarantee that
        ``cleanup_resources()`` will be able to remove all extracted files.

        (Note: you may not change the extraction path for a given resource
        manager once resources have been extracted, unless you first call

FileFinder��_namespace_handlers)�_namespace_packagescCs|t|<dS)a�Register `namespace_handler` to declare namespace packages

    `importer_type` is the type or class of a PEP 302 "Importer" (sys.path item
    handler), and `namespace_handler` is a callable like this::

        def namespace_handler(importer, path_entry, moduleName, module):
            # return a path_entry to use for child packages

    Namespace handlers are only called if the importer object has already
    agreed that it can handle the relevant path item, and they should only
    return a subpath if the module __path__ does not already contain an
    equivalent subpath.  For an example namespace handler, see

        Packages installed by distutils (e.g. numpy or scipy),
        which uses an old safe_version, and so
        their version numbers can get mangled when
        converted to filenames (e.g., 1.11.0.dev0+2329eae to
        1.11.0.dev0_2329eae). These distributions will not be
        parsed properly
        downstream by Distribution and safe_version, so
        take an extra step and try to get the version number from
        the metadata file itself instead of the filename.

        "appname" is the name of application.

            it is the owning company name. This falls back to appname. You may
            pass False to disable it.
        "version" is an optional version path element to append to the

            of your app to be able to run independently. If used, this
            would typically be "<major>.<minor>".
            Only applied when appname is present.
        "roaming" (boolean, default False) can be set True to use the Windows
            roaming appdata directory. That means that for users on a Windows
            network setup for roaming profiles, this user data will be
            sync'd on login. See

            of your app to be able to run independently. If used, this
            would typically be "<major>.<minor>".
            Only applied when appname is present.
        "multipath" is an optional parameter only applicable to *nix
            which indicates that the entire list of config dirs should be
            returned. By default, the first item from XDG_CONFIG_DIRS is
            returned, or '/etc/xdg/<AppName>', if XDG_CONFIG_DIRS is not set

    Typical site config directories are:
        Mac OS X:   same as site_data_dir
        Unix:       /etc/xdg/<AppName> or $XDG_CONFIG_DIRS[i]/<AppName> for each value in
                    $XDG_CONFIG_DIRS
        Win *:      same as site_data_dir
        Vista:      (Fail! "C:\ProgramData" is a hidden *system* directory on Vista.)

    For Unix, this is using the $XDG_CONFIG_DIRS[0] default, if multipath=False

    WARNING: Do not use this on Windows. See the Vista-Fail note above for why.

        "appname" is the name of application.
            If None, just the system directory is returned.
        "appauthor" (only used on Windows) is the name of the
            appauthor or distributing body for this application. Typically
            it is the owning company name. This falls back to appname. You may
            pass False to disable it.
        "version" is an optional version path element to append to the
            path. You might want to use this if you want multiple versions

            would typically be "<major>.<minor>".
            Only applied when appname is present.
        "opinion" (boolean) can be False to disable the appending of
            "Cache" to the base app data dir for Windows. See
            discussion below.

    Typical user cache directories are:
        Mac OS X:   ~/Library/Caches/<AppName>
        Unix:       ~/.cache/<AppName> (XDG default)
        Win XP:     C:\Documents and Settings\<username>\Local Settings\Application Data\<AppAuthor>\<AppName>\Cache
        Vista:      C:\Users\<username>\AppData\Local\<AppAuthor>\<AppName>\Cache

    On Windows the only suggestion in the MSDN docs is that local settings go in
    the `CSIDL_LOCAL_APPDATA` directory. This is identical to the non-roaming
    app data dir (the default returned by `user_data_dir` above). Apps typically
    put cache data somewhere *under* the given dir here. Some examples:
        ...\Mozilla\Firefox\Profiles\<ProfileName>\Cache
        ...\Acme\SuperApp\Cache\1.0
    OPINION: This function appends "Cache" to the `CSIDL_LOCAL_APPDATA` value.
    This can be disabled with the `opinion=False` option.

            would typically be "<major>.<minor>".
            Only applied when appname is present.
        "roaming" (boolean, default False) can be set True to use the Windows
            roaming appdata directory. That means that for users on a Windows
            network setup for roaming profiles, this user data will be
            sync'd on login. See
            <http://technet.microsoft.com/en-us/library/cc766489(WS.10).aspx>
            for a discussion of issues.

    Typical user state directories are:
        Mac OS X:  same as user_data_dir
        Unix:      ~/.local/state/<AppName>   # or in $XDG_STATE_HOME, if defined
        Win *:     same as user_data_dir

    For Unix, we follow this Debian proposal <https://wiki.debian.org/XDGBaseDirectorySpecification#state>
    to extend the XDG spec and support $XDG_STATE_HOME.

    That means, by default "~/.local/state/<AppName>".

        "opinion" (boolean) can be False to disable the appending of
            "Logs" to the base app data dir for Windows, and "log" to the
            base cache dir for Unix. See discussion below.

    Typical user log directories are:
        Mac OS X:   ~/Library/Logs/<AppName>
        Unix:       ~/.cache/<AppName>/log  # or under $XDG_CACHE_HOME if defined

        Vista:      C:\Users\<username>\AppData\Local\<AppAuthor>\<AppName>\Logs

    On Windows the only suggestion in the MSDN docs is that local settings
    go in the `CSIDL_LOCAL_APPDATA` directory. (Note: I'm interested in
    examples of what some windows apps use for a logs dir.)

    OPINION: This function appends "Logs" to the `CSIDL_LOCAL_APPDATA`
    value for Windows and appends "log" to the user cache dir for Unix.

pyparsing module - Classes and methods to define and execute parsing grammars
=============================================================================

The pyparsing module is an alternative approach to creating and executing simple grammars,
vs. the traditional lex/yacc approach, or the use of regular expressions.  With pyparsing, you
don't need to learn a new syntax for defining grammars or matching expressions - the parsing module
provides a library of classes that you use to construct the grammar directly in Python.

Here is a program to parse "Hello, World!" (or any greeting of the form 
C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements 
(L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to
L{Literal} expressions)::

    from pyparsing import Word, alphas

    # define grammar of a greeting
    greet = Word(alphas) + "," + Word(alphas) + "!"

    hello = "Hello, World!"
    print (hello, "->", greet.parseString(hello))

The program outputs the following::

    Hello, World! -> ['Hello', ',', 'World', '!']

The Python representation of the grammar is quite readable, owing to the self-explanatory
class names, and the use of '+', '|' and '^' operators.

The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an
object with named attributes.

The pyparsing module handles some of the problems that are typically vexing when writing text parsers:
 - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello  ,  World  !", etc.)
 - quoted strings
 - embedded comments


Getting Started -
-----------------
Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing
classes inherit from. Use the docstrings for examples of how to:
 - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes
 - construct character word-group expressions using the L{Word} class
 - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes
 - use L{'+'<And>}, L{'|'<MatchFirst>}, L{'^'<Or>}, and L{'&'<Each>} operators to combine simple expressions into more complex ones
 - associate names with your parsed results using L{ParserElement.setResultsName}
 - find some helpful expression short-cuts like L{delimitedList} and L{oneOf}
 - find more useful common expressions in the L{pyparsing_common} namespace class

        Removes and returns item at specified index (default=C{last}).
        Supports both C{list} and C{dict} semantics for C{pop()}. If passed no
        argument or an integer argument, it will use C{list} semantics
        and pop tokens from the list of parsed tokens. If passed a 
        non-integer argument (most likely a string), it will use C{dict}
        semantics and pop the corresponding value from any defined 
        results names. A second default return value argument is 
        supported, just as in C{dict.pop()}.

        Example::
            def remove_first(tokens):
                tokens.pop(0)
            print(OneOrMore(Word(nums)).parseString("0 123 321")) # -> ['0', '123', '321']
            print(OneOrMore(Word(nums)).addParseAction(remove_first).parseString("0 123 321")) # -> ['123', '321']

            label = Word(alphas)
            patt = label("LABEL") + OneOrMore(Word(nums))
            print(patt.parseString("AAB 123 321").dump())

            # Use pop() in a parse action to remove named result (note that corresponding value is not
            # removed from list form of results)
            def remove_LABEL(tokens):
                tokens.pop("LABEL")
                return tokens
            patt.addParseAction(remove_LABEL)
            print(patt.parseString("AAB 123 321").dump())
        prints::
            ['AAB', '123', '321']

        Similar to C{dict.get()}.

        Make a copy of this C{ParserElement}.  Useful for defining different parse actions
        for the same parsing pattern, using copies of the original parse element.
        
        Example::
            integer = Word(nums).setParseAction(lambda toks: int(toks[0]))
            integerK = integer.copy().addParseAction(lambda toks: toks[0]*1024) + Suppress("K")
            integerM = integer.copy().addParseAction(lambda toks: toks[0]*1024*1024) + Suppress("M")
            
            print(OneOrMore(integerK | integerM | integer).parseString("5K 100 640K 256M"))
        prints::
            [5120, 100, 655360, 268435456]
        Equivalent form of C{expr.copy()} is just C{expr()}::
            integerM = integer().addParseAction(lambda toks: toks[0]*1024*1024) + Suppress("M")

        Define name for referencing matching tokens as a nested attribute
        of the returned parse results.
        NOTE: this returns a *copy* of the original C{ParserElement} object;
        this is so that the client can define a basic element, such as an
        integer, and reference it in multiple places with different names.

        You can also set results names using the abbreviated syntax,
        C{expr("name")} in place of C{expr.setResultsName("name")} - 
        see L{I{__call__}<__call__>}.

        Example::

        Define one or more actions to perform when successfully matching parse element definition.
        Parse action fn is a callable method with 0-3 arguments, called as C{fn(s,loc,toks)},
        C{fn(loc,toks)}, C{fn(toks)}, or just C{fn()}, where:
         - s   = the original string being parsed (see note below)
         - loc = the location of the matching substring
         - toks = a list of the matched tokens, packaged as a C{L{ParseResults}} object
        If the functions in fns modify the tokens, they can return them as the return
        value from fn, and the modified list of tokens will replace the original.
        Otherwise, fn does not need to return any value.

        Optional keyword arguments:
         - callDuringTry = (default=C{False}) indicate if parse action should be run during lookaheads and alternate testing

        Note: the default parsing behavior is to expand tabs in the input string
        before starting the parsing process.  See L{I{parseString}<parseString>} for more information
        on parsing strings containing C{<TAB>}s, and suggested methods to maintain a
        consistent view of the parsed string, the parse location, and line and column
        positions within the parsed string.
        
        Example::
            integer = Word(nums)
            date_str = integer + '/' + integer + '/' + integer

            date_str.parseString("1999/12/31")  # -> ['1999', '/', '12', '/', '31']

            # use parse action to convert to ints at parse time
            integer = Word(nums).setParseAction(lambda toks: int(toks[0]))
            date_str = integer + '/' + integer + '/' + integer

            # note that integer fields are now ints, not strings
            date_str.parseString("1999/12/31")  # -> [1999, '/', 12, '/', 31]

resetCaches
zParserElement.resetCache�cCs8tjs4dt_|dkr t��t_nt�|�t_tjt_dS)a�Enables "packrat" parsing, which adds memoizing to the parsing logic.
           Repeated parse attempts at the same string location (which happens
           often in many complex grammars) can immediately return a cached value,
           instead of re-executing parsing/validating code.  Memoizing is done of
           both valid results and parsing exceptions.
           
           Parameters:
            - cache_size_limit - (default=C{128}) - if an integer value is provided
              will limit the size of the packrat cache; if None is passed, then
              the cache size will be unbounded; if 0 is passed, the cache will
              be effectively disabled.
            
           This speedup may break existing programs that use parse actions that
           have side-effects.  For this reason, packrat parsing is disabled when
           you first import pyparsing.  To activate the packrat feature, your
           program must call the class method C{ParserElement.enablePackrat()}.  If
           your program uses C{psyco} to "compile as you go", you must call
           C{enablePackrat} before calling C{psyco.full()}.  If you do not do this,
           Python will crash.  For best results, call C{enablePackrat()} immediately
           after importing pyparsing.
           
           Example::
               import pyparsing
               pyparsing.ParserElement.enablePackrat()

        Execute the parse expression with the given string.
        This is the main interface to the client code, once the complete
        expression has been built.

        If you want the grammar to require that the entire input string be
        successfully parsed, then set C{parseAll} to True (equivalent to ending
        the grammar with C{L{StringEnd()}}).

        Note: C{parseString} implicitly calls C{expandtabs()} on the input string,
        in order to report proper column numbers in parse actions.
        If the input string contains tabs and
        the grammar uses parse actions that use the C{loc} argument to index into the
        string being parsed, you can ensure you have a consistent view of the input
        string by:
         - calling C{parseWithTabs} on your grammar before calling C{parseString}
           (see L{I{parseWithTabs}<parseWithTabs>})
         - define your parse action using the full C{(s,loc,toks)} signature, and
           reference the input string using the parse action's C{s} argument
         - explictly expand the tabs in your input string before calling
           C{parseString}
        
        Example::
            Word('a').parseString('aaaaabaaa')  # -> ['aaaaa']
            Word('a').parseString('aaaaabaaa', parseAll=True)  # -> Exception: Expected end of text

        Scan the input string for expression matches.  Each match will return the
        matching tokens, start location, and end location.  May be called with optional
        C{maxMatches} argument, to clip scanning after 'n' matches are found.  If
        C{overlap} is specified, then overlapping matches will be reported.

        Note that the start and end locations are reported relative to the string
        being parsed.  See L{I{parseString}<parseString>} for more information on parsing
        strings with embedded tabs.

        Example::

        Extension to C{L{scanString}}, to modify matching text with modified tokens that may
        be returned from a parse action.  To use C{transformString}, define a grammar and
        attach a parse action to it that modifies the returned token list.
        Invoking C{transformString()} on a target string will then scan for matches,
        and replace the matched text patterns according to the logic in the parse
        action.  C{transformString()} returns the resulting transformed string.
        
        Example::
            wd = Word(alphas)
            wd.setParseAction(lambda toks: toks[0].title())
            
            print(wd.transformString("now is the winter of our discontent made glorious summer by this sun of york."))
        Prints::
            Now Is The Winter Of Our Discontent Made Glorious Summer By This Sun Of York.

        Implementation of * operator, allows use of C{expr * 3} in place of
        C{expr + expr + expr}.  Expressions may also me multiplied by a 2-integer
        tuple, similar to C{{min,max}} multipliers in regular expressions.  Tuples
        may also include C{None} as in:
         - C{expr*(n,None)} or C{expr*(n,)} is equivalent
              to C{expr*n + L{ZeroOrMore}(expr)}
              (read as "at least n instances of C{expr}")
         - C{expr*(None,n)} is equivalent to C{expr*(0,n)}
              (read as "0 to n instances of C{expr}")
         - C{expr*(None,None)} is equivalent to C{L{ZeroOrMore}(expr)}
         - C{expr*(1,None)} is equivalent to C{L{OneOrMore}(expr)}

        Note that C{expr*(None,n)} does not raise an exception if
        more than n exprs exist in the input stream; that is,
        C{expr*(None,n)} does not enforce a maximum number of expr
        occurrences.  If this behavior is desired, then write
        C{expr*(None,n) + ~expr}

            Exception raised:Expected alphaword (at char 15), (line:1, col:16)

        The output shown is that produced by the default debug actions - custom debug actions can be
        specified using L{setDebugActions}. Prior to attempting
        to match the C{wd} expression, the debugging message C{"Match <exprname> at loc <n>(<line>,<col>)"}
        is shown. Then if the parse succeeds, a C{"Matched"} message is shown, or an C{"Exception raised"}
        message is shown. Also note the use of L{setName} to assign a human-readable name to the expression,
        which makes debugging and exception messages easier to understand - for instance, the default
        name created for the C{Word} expression without calling C{setName} is C{"W:(ABCD...)"}.

        Execute the parse expression on a series of test strings, showing each
        test, the parsed results or where the parse failed. Quick and easy way to
        run a parse expression against a list of sample strings.
           
        Parameters:
         - tests - a list of separate test strings, or a multiline string of test strings
         - parseAll - (default=C{True}) - flag to pass to C{L{parseString}} when running tests           
         - comment - (default=C{'#'}) - expression for indicating embedded comments in the test 
              string; pass None to disable comment filtering
         - fullDump - (default=C{True}) - dump results as list followed by results names in nested outline;
              if False, only dump nested list
         - printResults - (default=C{True}) prints test output to stdout
         - failureTests - (default=C{False}) indicates if these tests are expected to fail parsing

        Returns: a (success, results) tuple, where success indicates that all tests succeeded
        (or failed if C{failureTests} is True), and the results contain a list of lines of each 
        test's output
        
        Example::
            number_expr = pyparsing_common.number.copy()

        lines, create a test like this::

            expr.runTest(r"this is a test\n of strings that spans \n 3 lines")
        
        (Note that this is a raw string literal, you must include the leading 'r'.)

    Token to exactly match a specified string as a keyword, that is, it must be
    immediately followed by a non-keyword character.  Compare with C{L{Literal}}:
     - C{Literal("if")} will match the leading C{'if'} in C{'ifAndOnlyIf'}.
     - C{Keyword("if")} will not; it will only match the leading C{'if'} in C{'if x=1'}, or C{'if(y==2)'}
    Accepts two optional constructor arguments in addition to the keyword string:
     - C{identChars} is a string of characters that would be valid identifier characters,
          defaulting to all alphanumerics + "_" and "$"
     - C{caseless} allows case-insensitive matching, default is C{False}.
       
    Example::
        Keyword("start").parseString("start")  # -> ['start']
        Keyword("start").parseString("starting")  # -> Exception

    For case-insensitive matching, use L{CaselessKeyword}.

rnax
    A variation on L{Literal} which matches "close" matches, that is, 
    strings with at most 'n' mismatching characters. C{CloseMatch} takes parameters:
     - C{match_string} - string to be matched
     - C{maxMismatches} - (C{default=1}) maximum number of mismatches allowed to count as a match
    
    The results from a successful parse will contain the matched text from the input string and the following named results:
     - C{mismatches} - a list of the positions within the match_string where mismatches were found
     - C{original} - the original match_string used to compare against the input string
    
    If C{mismatches} is an empty list, then the match was an exact match.
    
    Example::
        patt = CloseMatch("ATCATCGAATGGA")
        patt.parseString("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']})
        patt.parseString("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1)

        # exact match
        patt.parseString("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']})

        # close match allowing up to 2 mismatches
        patt = CloseMatch("ATCATCGAATGGA", maxMismatches=2)
        patt.parseString("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']})

�Z�fdd�Z�ZS)r1a	
    Token for matching words composed of allowed character sets.
    Defined with string containing all allowed initial characters,
    an optional string containing allowed body characters (if omitted,
    defaults to the initial character set), and an optional minimum,
    maximum, and/or exact length.  The default value for C{min} is 1 (a
    minimum value < 1 is not valid); the default values for C{max} and C{exact}
    are 0, meaning no maximum or exact length restriction. An optional
    C{excludeChars} parameter can list characters that might be found in 
    the input C{bodyChars} string; useful to define a word of all printables
    except for one or two characters, for instance.
    
    L{srange} is useful for defining custom character set strings for defining 
    C{Word} expressions, using range notation from regular expression character sets.
    
    A common mistake is to use C{Word} to match a specific literal string, as in 
    C{Word("Address")}. Remember that C{Word} uses the string argument to define
    I{sets} of matchable characters. This expression would match "Add", "AAA",
    "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'.
    To match an exact literal string, use L{Literal} or L{Keyword}.

    pyparsing includes helper strings for building Words:
     - L{alphas}
     - L{nums}
     - L{alphanums}
     - L{hexnums}
     - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.)
     - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.)
     - L{printables} (any non-whitespace character)

    Example::
        # a word composed of digits
        integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9"))
        
        # a word with a leading capital, and zero or more lowercase
        capital_word = Word(alphas.upper(), alphas.lower())

        # hostnames are alphanumeric, with leading alpha, and '-'
        hostname = Word(alphas, alphanums+'-')
        
        # roman numeral (not a strict parser, accepts invalid mix of characters)
        roman = Word("IVXLCDM")
        
        # any string of non-whitespace characters, except for ','
        csv_value = Word(printables, excludeChars=",")

    Token for matching strings that are delimited by quoting characters.
    
    Defined with the following parameters:
        - quoteChar - string of one or more characters defining the quote delimiting string
        - escChar - character to escape quotes, typically backslash (default=C{None})
        - escQuote - special quote sequence to escape an embedded quote string (such as SQL's "" to escape an embedded ") (default=C{None})
        - multiline - boolean indicating whether quotes can span multiple lines (default=C{False})
        - unquoteResults - boolean indicating whether the matched text should be unquoted (default=C{True})
        - endQuoteChar - string of one or more characters defining the end of the quote delimited string (default=C{None} => same as quoteChar)
        - convertWhitespaceEscapes - convert escaped whitespace (C{'\t'}, C{'\n'}, etc.) to actual whitespace (default=C{True})

    Example::
        qs = QuotedString('"')
        print(qs.searchString('lsjdf "This is the quote" sldjf'))
        complex_qs = QuotedString('{{', endQuoteChar='}}')
        print(complex_qs.searchString('lsjdf {{This is the "quote"}} sldjf'))
        sql_qs = QuotedString('"', escQuote='""')
        print(sql_qs.searchString('lsjdf "This is the quote with ""embedded"" quotes" sldjf'))
    prints::

    Token for matching words composed of characters I{not} in a given set (will
    include whitespace in matched characters if not listed in the provided exclusion set - see example).
    Defined with string containing all disallowed characters, and an optional
    minimum, maximum, and/or exact length.  The default value for C{min} is 1 (a
    minimum value < 1 is not valid); the default values for C{max} and C{exact}
    are 0, meaning no maximum or exact length restriction.

    Example::

    Repetition of one or more of the given expression.
    
    Parameters:
     - expr - expression that must match one or more times
     - stopOn - (default=C{None}) - expression for a terminating sentinel
          (only required if the sentinel would ordinarily match the repetition 
          expression)          

    Example::
        data_word = Word(alphas)
        label = data_word + FollowedBy(':')
        attr_expr = Group(label + Suppress(':') + OneOrMore(data_word).setParseAction(' '.join))

        text = "shape: SQUARE posn: upper left color: BLACK"
        OneOrMore(attr_expr).parseString(text).pprint()  # Fail! read 'color' as data instead of next label -> [['shape', 'SQUARE color']]

        # use stopOn attribute for OneOrMore to avoid reading label string as part of the data
        attr_expr = Group(label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join))
        OneOrMore(attr_expr).parseString(text).pprint() # Better -> [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'BLACK']]
        
        # could also be written as

    Token for skipping over all undefined text until the matched expression is found.

    Parameters:
     - expr - target expression marking the end of the data to be skipped
     - include - (default=C{False}) if True, the target expression is also parsed 
          (the skipped text and target expression are returned as a 2-element list).
     - ignore - (default=C{None}) used to define grammars (typically quoted strings and 
          comments) that might contain false matches to the target expression
     - failOn - (default=C{None}) define expressions that are not allowed to be 
          included in the skipped test; if found before the target expression is found, 
          the SkipTo is not a match

    Example::
        report = '''

    Forward declaration of an expression to be defined later -
    used for recursive grammars, such as algebraic infix notation.
    When the expression is known, it is assigned to the C{Forward} variable using the '<<' operator.

    Note: take care when assigning to C{Forward} not to overlook precedence of operators.
    Specifically, '|' has a lower precedence than '<<', so that::
        fwdExpr << a | b | c
    will actually be evaluated as::
        (fwdExpr << a) | b | c
    thereby leaving b and c out as parseable alternatives.  It is recommended that you
    explicitly group the values inserted into the C{Forward}::
        fwdExpr << (a | b | c)
    Converting to use the '<<=' operator instead will avoid this problem.

    See L{ParseResults.pprint} for an example of a recursive parser created using
    C{Forward}.

    Converter to concatenate all matching tokens to a single string.
    By default, the matching patterns must also be contiguous in the input string;
    this can be disabled by specifying C{'adjacent=False'} in the constructor.

    Example::
        real = Word(nums) + '.' + Word(nums)
        print(real.parseString('3.1416')) # -> ['3', '.', '1416']
        # will also erroneously match the following
        print(real.parseString('3. 1416')) # -> ['3', '.', '1416']

        real = Combine(Word(nums) + '.' + Word(nums))
        print(real.parseString('3.1416')) # -> ['3.1416']
        # no match when there are internal spaces
        print(real.parseString('3. 1416')) # -> Exception: Expected W:(0123...)

    Converter to return a repetitive expression as a list, but also as a dictionary.
    Each element can also be referenced using the first token in the expression as its key.
    Useful for tabular report scraping when the first column can be used as a item key.

        print(OneOrMore(attr_expr).parseString(text).dump())
        
        # instead of OneOrMore(expr), parse using Dict(OneOrMore(Group(expr))) - Dict will auto-assign names
        result = Dict(OneOrMore(Group(attr_expr))).parseString(text)
        print(result.dump())
        
        # access named fields as dict entries, or output as dict
        print(result['shape'])        
        print(result.asDict())
    prints::
        ['shape', 'SQUARE', 'posn', 'upper left', 'color', 'light blue', 'texture', 'burlap']

        [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'light blue'], ['texture', 'burlap']]
        - color: light blue
        - posn: upper left
        - shape: SQUARE
        - texture: burlap
        SQUARE

    Decorator for debugging parse actions. 
    
    When the parse action is called, this decorator will print C{">> entering I{method-name}(line:I{current_source_line}, I{parse_location}, I{matched_tokens})".}
    When the parse action completes, the decorator will print C{"<<"} followed by the returned value, or any exception that the parse action raised.

    Helper to define a delimited list of expressions - the delimiter defaults to ','.
    By default, the list elements and delimiters can have intervening whitespace, and
    comments, but this can be overridden by passing C{combine=True} in the constructor.
    If C{combine} is set to C{True}, the matching tokens are returned as a single token
    string, with the delimiters included; otherwise, the matching tokens are returned
    as a list of tokens, with the delimiters suppressed.

    Example::
        delimitedList(Word(alphas)).parseString("aa,bb,cc") # -> ['aa', 'bb', 'cc']
        delimitedList(Word(hexnums), delim=':', combine=True).parseString("AA:BB:CC:DD:EE") # -> ['AA:BB:CC:DD:EE']

    Helper to define a counted list of expressions.
    This helper defines a pattern of the form::
        integer expr expr expr...
    where the leading integer tells how many expr expressions follow.
    The matched tokens returns the array of expr tokens as a list - the leading count token is suppressed.
    
    If C{intExpr} is specified, it should be a pyparsing expression that produces an integer value.

    Example::
        countedArray(Word(alphas)).parseString('2 ab cd ef')  # -> ['ab', 'cd']

        # in this parser, the leading integer value is given in binary,
        # '10' indicating that 2 values are in the array
        binaryConstant = Word('01').setParseAction(lambda t: int(t[0], 2))

    Helper to define an expression that is indirectly defined from

        first = Word(nums)
        second = matchPreviousLiteral(first)
        matchExpr = first + ":" + second
    will match C{"1:1"}, but not C{"1:2"}.  Because this matches a
    previous literal, will also match the leading C{"1:1"} in C{"1:10"}.
    If this is not desired, use C{matchPreviousExpr}.

        second = matchPreviousExpr(first)
        matchExpr = first + ":" + second
    will match C{"1:1"}, but not C{"1:2"}.  Because this matches by
    expressions, will I{not} match the leading C{"1:1"} in C{"1:10"};
    the expressions are evaluated first, and then compared, so
    C{"1"} is compared with C{"10"}.
    Do I{not} use with packrat parsing enabled.

    Helper to quickly define a set of alternative Literals, and makes sure to do
    longest-first testing when there is a conflict, regardless of the input order,
    but returns a C{L{MatchFirst}} for best performance.

    Parameters:
     - strs - a string of space-delimited literals, or a collection of string literals
     - caseless - (default=C{False}) - treat all literals as caseless
     - useRegex - (default=C{True}) - as an optimization, will generate a Regex
          object; otherwise, will generate a C{MatchFirst} object (if C{caseless=True}, or
          if creating a C{Regex} raises an exception)

    Example::
        comp_oper = oneOf("< = > <= >= !=")
        var = Word(alphas)
        number = Word(nums)
        term = var | number
        comparison_expr = term + comp_oper + term
        print(comparison_expr.searchString("B = 12  AA=23 B<=AA AA>12"))
    prints::
        [['B', '=', '12'], ['AA', '=', '23'], ['B', '<=', 'AA'], ['AA', '>', '12']]

    Helper to easily and clearly define a dictionary by specifying the respective patterns
    for the key and value.  Takes care of defining the C{L{Dict}}, C{L{ZeroOrMore}}, and C{L{Group}} tokens
    in the proper order.  The key pattern can include delimiting markers or punctuation,
    as long as they are suppressed, thereby leaving the significant key text.  The value
    pattern can include named results, so that the C{Dict} results can include named token
    fields.

    Example::
        text = "shape: SQUARE posn: upper left color: light blue texture: burlap"
        attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join))
        print(OneOrMore(attr_expr).parseString(text).dump())
        
        attr_label = label
        attr_value = Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join)

        # similar to Dict, but simpler call format
        result = dictOf(attr_label, attr_value).parseString(text)
        print(result.dump())
        print(result['shape'])
        print(result.shape)  # object attribute access works too
        print(result.asDict())
    prints::
        [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'light blue'], ['texture', 'burlap']]
        - color: light blue
        - posn: upper left
        - shape: SQUARE
        - texture: burlap
        SQUARE
        SQUARE
        {'color': 'light blue', 'shape': 'SQUARE', 'posn': 'upper left', 'texture': 'burlap'}

    Helper to return the original, untokenized text for a given expression.  Useful to
    restore the parsed fields of an HTML start tag into the raw tag text itself, or to
    revert separate tokens with intervening whitespace back to the original matching
    input text. By default, returns astring containing the original parsed text.  
       
    If the optional C{asString} argument is passed as C{False}, then the return value is a 
    C{L{ParseResults}} containing any results names that were originally matched, and a 
    single token containing the original matched text from the input string.  So if 
    the expression passed to C{L{originalTextFor}} contains expressions with defined
    results names, you must set C{asString} to C{False} if you want to preserve those
    results name values.

    Example::
        src = "this is test <b> bold <i>text</i> </b> normal text "
        for tag in ("b","i"):
            opener,closer = makeHTMLTags(tag)
            patt = originalTextFor(opener + SkipTo(closer) + closer)
            print(patt.searchString(src)[0])
    prints::
        ['<b> bold <i>text</i> </b>']

    Helper to decorate a returned token with its starting and ending locations in the input string.
    This helper adds the following results names:
     - locn_start = location where matched expression begins
     - locn_end = location where matched expression ends
     - value = the actual parsed results

    Be careful if the input text contains C{<TAB>} characters, you may want to call
    C{L{ParserElement.parseWithTabs}}

    Example::
        wd = Word(alphas)
        for match in locatedExpr(wd).searchString("ljsdf123lksdjjf123lkkjj1222"):
            print(match)
    prints::

    Helper to easily define string ranges for use in Word construction.  Borrows

        srange("[a-z]")   -> "abcdefghijklmnopqrstuvwxyz"
        srange("[a-z$_]") -> "abcdefghijklmnopqrstuvwxyz$_"
    The input string must be enclosed in []'s, and the returned string is the expanded
    character set joined into a single string.
    The values enclosed in the []'s may be:
     - a single character
     - an escaped character with a leading backslash (such as C{\-} or C{\]})
     - an escaped hex character with a leading C{'\x'} (C{\x21}, which is a C{'!'} character) 
         (C{\0x##} is also supported for backwards compatibility) 
     - an escaped octal character with a leading C{'\0'} (C{\041}, which is a C{'!'} character)
     - a range of any of the above, separated by a dash (C{'a-z'}, etc.)
     - any combination of the above (C{'aeiouy'}, C{'a-zA-Z0-9_$'}, etc.)

    Helper to define a parse action by mapping a function to all elements of a ParseResults list.If any additional 
    args are passed, they are forwarded to the given function as additional arguments after
    the token, as in C{hex_integer = Word(hexnums).setParseAction(tokenMap(int, 16))}, which will convert the
    parsed data to an integer using base 16.

    Example (compare the last to example in L{ParserElement.transformString}::

    Helper to construct opening and closing tag expressions for XML, given a tag name. Matches

    Tr�r�ryryrzrN;scs8|r|dd��n|���dd��D���fdd�}|S)a<
    Helper to create a validating parse action to be used with start tags created
    with C{L{makeXMLTags}} or C{L{makeHTMLTags}}. Use C{withAttribute} to qualify a starting tag
    with a required attribute value, to avoid false matches on common tags such as
    C{<TD>} or C{<DIV>}.

    Call C{withAttribute} with a series of attribute names and values. Specify the list
    of filter attributes names and values as:
     - keyword arguments, as in C{(align="right")}, or
     - as an explicit dict with C{**} operator, when an attribute name is also a Python
          reserved word, as in C{**{"class":"Customer", "align":"right"}}
     - a list of name-value tuples, as in ( ("ns1:class", "Customer"), ("ns2:align","right") )
    For attribute names with a namespace prefix, you must use the second form.  Attribute
    names are matched insensitive to upper/lower case.
       
    If just testing for C{class} (with or without a namespace), use C{L{withClass}}.

    To verify that the attribute exists, but without specifying a value, pass
    C{withAttribute.ANY_VALUE} as the value.

    Example::
        html = '''

    Helper method for constructing grammars of expressions made up of
    operators working in a precedence hierarchy.  Operators may be unary or
    binary, left- or right-associative.  Parse actions can also be attached
    to operator expressions. The generated parser will also recognize the use 
    of parentheses to override operator precedences (see example below).
    
    Note: if you define a deep operator list, you may see performance issues
    when using infixNotation. See L{ParserElement.enablePackrat} for a
    mechanism to potentially improve your parser performance.

    Parameters:
     - baseExpr - expression representing the most basic element for the nested
     - opList - list of tuples, one for each operator precedence level in the
      expression grammar; each tuple is of the form
      (opExpr, numTerms, rightLeftAssoc, parseAction), where:
       - opExpr is the pyparsing expression for the operator;
          may also be a string, which will be converted to a Literal;
          if numTerms is 3, opExpr is a tuple of two expressions, for the
          two operators separating the 3 terms
       - numTerms is the number of terms for this operator (must
          be 1, 2, or 3)
       - rightLeftAssoc is the indicator whether the operator is
          right or left associative, using the pyparsing-defined
          constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}.
       - parseAction is the parse action to be associated with
          expressions matching this operator expression (the
          parse action tuple member may be omitted); if the parse action
          is passed a tuple or list of functions, this is equivalent to
          calling C{setParseAction(*fn)} (L{ParserElement.setParseAction})
     - lpar - expression for matching left-parentheses (default=C{Suppress('(')})
     - rpar - expression for matching right-parentheses (default=C{Suppress(')')})

    Example::
        # simple example of four-function arithmetic with ints and variable names
        integer = pyparsing_common.signed_integer

    Helper method for defining nested lists enclosed in opening and closing
    delimiters ("(" and ")" are the default).

    Parameters:
     - opener - opening character for a nested list (default=C{"("}); can also be a pyparsing expression
     - closer - closing character for a nested list (default=C{")"}); can also be a pyparsing expression
     - content - expression for items within the nested lists (default=C{None})
     - ignoreExpr - expression for ignoring opening and closing delimiters (default=C{quotedString})

    If an expression is not provided for the content argument, the nested
    expression will capture all whitespace-delimited content between delimiters
    as a list of separate values.

    Use the C{ignoreExpr} argument to define expressions that may contain
    opening or closing characters that should not be treated as opening
    or closing characters for nesting, such as quotedString or a comment
    expression.  Specify multiple expressions using an C{L{Or}} or C{L{MatchFirst}}.
    The default is L{quotedString}, but if no expressions are to be ignored,
    then pass C{None} for this argument.

    Example::
        data_type = oneOf("void int short long char float double")
        decl_data_type = Combine(data_type + Optional(Word('*')))
        ident = Word(alphas+'_', alphanums+'_')
        number = pyparsing_common.number
        arg = Group(decl_data_type + ident)
        LPAR,RPAR = map(Suppress, "()")

        code_body = nestedExpr('{', '}', ignoreExpr=(quotedString | cStyleComment))

        c_function = (decl_data_type("type") 
                      + ident("name")
                      + LPAR + Optional(delimitedList(arg), [])("args") + RPAR 
                      + code_body("body"))
        c_function.ignore(cStyleComment)
        
        source_code = '''

            int dec_to_hex(char hchar) { 
                if (hchar >= '0' && hchar <= '9') { 
                    return (ord(hchar)-ord('0')); 
                } else { 
                    return (10+ord(hchar)-ord('A'));
                }

        for func in c_function.searchString(source_code):

    Helper method for defining space-delimited indentation blocks, such as
    those used to define block statements in Python source code.

    Parameters:
     - blockStatementExpr - expression defining syntax of statement that
            is repeated within the indented block
     - indentStack - list created by caller to manage indentation stack
            (multiple statementWithIndentedBlock expressions within a single grammar
            should share a common indentStack)
     - indent - boolean indicating whether block must be indented beyond the
            the current level; set to False for block of left-most statements
            (default=C{True})

    A valid block must contain at least one C{blockStatement}.

    Example::
        data = '''
        def A(z):
          A1
          B = 100
          G = A2
          A2
          A3
        B
        def BB(a,b,c):
          BB1
          def BBA():
            bba1
            bba2
            bba3
        C
        D
        def spam(x,y):
             def eggs(z):
                 pass
        '''

        identifier = Word(alphas, alphanums)
        funcDecl = ("def" + identifier + Group( "(" + Optional( delimitedList(identifier) ) + ")" ) + ":")
        func_body = indentedBlock(stmt, indentStack)
        funcDef = Group( funcDecl + func_body )

        rvalue = Forward()
        funcCall = Group(identifier + "(" + Optional(delimitedList(rvalue)) + ")")
        rvalue << (funcCall | identifier | Word(nums))
        assignment = Group(identifier + "=" + rvalue)
        stmt << ( funcDef | assignment | identifier )

    Here are some common low-level expressions that may be useful in jump-starting parser development:
     - numeric forms (L{integers<integer>}, L{reals<real>}, L{scientific notation<sci_real>})
     - common L{programming identifiers<identifier>}
     - network addresses (L{MAC<mac_address>}, L{IPv4<ipv4_address>}, L{IPv6<ipv6_address>})
     - ISO8601 L{dates<iso8601_date>} and L{datetime<iso8601_datetime>}
     - L{UUID<uuid>}
     - L{comma-separated list<comma_separated_list>}
    Parse actions:
     - C{L{convertToInteger}}
     - C{L{convertToFloat}}
     - C{L{convertToDate}}
     - C{L{convertToDatetime}}
     - C{L{stripHTMLTags}}
     - C{L{upcaseTokens}}
     - C{L{downcaseTokens}}

e!�d/d0�Z$e%d1k�r"e$�dS)5a�Append module search paths for third-party packages to sys.path.

****************************************************************
* This module is automatically imported during initialization. *
****************************************************************

This will append site-specific paths to the module search path.  On
Unix (including Mac OSX), it starts with sys.prefix and
sys.exec_prefix (if different) and appends
lib/python3/dist-packages.
On other platforms (such as Windows), it tries each of the
prefixes directly, as well as with lib/site-packages appended.  The
resulting directories, if they exist, are appended to sys.path, and
also inspected for path configuration files.

For Debian and derivatives, this sys.path is augmented with directories
for packages distributed within the distribution. Local addons go
into /usr/local/lib/python<version>/dist-packages, Debian addons
install into /usr/lib/python3/dist-packages.
/usr/lib/python<version>/site-packages is not used.

If a file named "pyvenv.cfg" exists one directory above sys.executable,
sys.prefix and sys.exec_prefix are set to that directory and
it is also checked for site-packages (sys.base_prefix and
sys.base_exec_prefix will always be the "real" prefixes of the Python
installation). If "pyvenv.cfg" (a bootstrap configuration file) contains
the key "include-system-site-packages" set to anything other than "false"
(case-insensitive), the system-level prefixes will still also be
searched for site-packages; otherwise they won't.

All of the resulting site-specific directories, if they exist, are
appended to sys.path, and also inspected for path configuration
files.

A path configuration file is a file whose name has the form
<package>.pth; its contents are additional directories (one per line)
to be added to sys.path.  Non-existing directories (or
non-directories) are never added to sys.path; no directory is added to
sys.path more than once.  Blank lines and lines beginning with
'#' are skipped. Lines starting with 'import' are executed.

For example, suppose sys.prefix and sys.exec_prefix are set to
/usr/local and there is a directory /usr/local/lib/python2.5/site-packages
with three subdirectories, foo, bar and spam, and two path
configuration files, foo.pth and bar.pth.  Assume foo.pth contains the
following:

  # foo package configuration
  foo
  bar
  bletch

and bar.pth contains:

  # bar package configuration
  bar

Then the following directories are added to sys.path, in this order:

  /usr/local/lib/python2.5/site-packages/bar
  /usr/local/lib/python2.5/site-packages/foo

Note that bletch is omitted because it doesn't exist; bar precedes foo
because bar.pth comes alphabetically before foo.pth; and spam is
omitted because it is not mentioned in either path configuration file.

The readline module is also automatically configured to enable
completion for systems that support it.  This can be overridden in
sitecustomize, usercustomize or PYTHONSTARTUP.  Starting Python in
isolated mode (-I) disables automatic readline configuration.

After these operations, an attempt is made to import a module
named sitecustomize, which can perform arbitrary additional
site-specific customizations.  If this import fails with an
ImportError exception, it is silently ignored.

        Let SSL know where we can find trusted certificates for the certificate
        chain.  Note that the certificates have to be in PEM format.

        If capath is passed, it must be a directory prepared using the
        ``c_rehash`` tool included with OpenSSL.  Either, but not both, of
        *pemfile* or *capath* may be :data:`None`.

        Set the passphrase callback.  This function will be called
        when a private key with a passphrase is loaded.

        :param callback: The Python callback to use.  This must accept three
            positional arguments.  First, an integer giving the maximum length
            of the passphrase it may return.  If the returned passphrase is
            longer than this, it will be truncated.  Second, a boolean value
            which will be true if the user should be prompted for the
            passphrase twice and the callback should verify that the two values
            supplied are equal. Third, the value given as the *userdata*
            parameter to :meth:`set_passwd_cb`.  The *callback* must return
            a byte string. If an error occurs, *callback* should return a false

        Specify that the platform provided CA certificates are to be used for
        verification purposes. This method has some caveats related to the
        binary wheels that cryptography (pyOpenSSL's primary dependency) ships:

        *   macOS will only load certificates using this method if the user has
            the ``openssl@1.1`` `Homebrew <https://brew.sh>`_ formula installed
            in the default location.
        *   Windows will not work.
        *   manylinux1 cryptography wheels will work on most common Linux
            distributions in pyOpenSSL 17.1.0 and above.  pyOpenSSL detects the
            manylinux1 wheel and attempts to load roots via a fallback path.

        :return: bool
        apathaisfileaload_verify_locationsaisdiru
        Default verify paths are based on the compiled version of OpenSSL.
        However, when pyca/cryptography is compiled as a manylinux1 wheel
        that compiled location can potentially be wrong. So, like Go, we
        will try a predefined set of paths and attempt to load roots
        from there.

    An error occurred in an `OpenSSL.SSL` API.
    u
    A base class for wrapper classes that allow for intelligent exception
    handling in OpenSSL callbacks.

    :ivar list _problems: Any exceptions that occurred while executing in a
        context where they could not be raised in the normal way.  Typically
        this is because OpenSSL has called into some Python code and requires a
        return value.  The exceptions are saved to be raised later when it is
        possible to do so.
    u_CallbackExceptionHelper.__init__u_CallbackExceptionHelper.raise_if_problemu
    Wrap a callback such that it can be used as a certificate verification
    callback.
    u_VerifyHelper.__init__u
    Wrap a callback such that it can be used as an NPN advertisement callback.
    u_NpnAdvertiseHelper.__init__u
    Wrap a callback such that it can be used as an NPN selection callback.
    u_NpnSelectHelper.__init__u
    Wrap a callback such that it can be used as an ALPN selection callback.
    u_ALPNSelectHelper.__init__u
    Wrap a callback such that it can be used as an OCSP callback for the server
    side.

    Annoyingly, OpenSSL defines one OCSP callback but uses it in two different
    ways. For servers, that callback is expected to retrieve some OCSP data and
    hand it to OpenSSL, and may return only SSL_TLSEXT_ERR_OK,
    SSL_TLSEXT_ERR_FATAL, and SSL_TLSEXT_ERR_NOACK. For clients, that callback
    is expected to check the OCSP data, and returns a negative value on error,
    0 if the response is not acceptable, or positive if it is. These are
    mutually exclusive return code behaviours, and they mean that we need two
    helpers so that we always return an appropriate error code if the user's
    code throws an exception.

    Given that we have to have two helpers anyway, these helpers are a bit more
    helpery than most: specifically, they hide a few more of the OpenSSL
    functions so that the user has an easier time writing these callbacks.

    This helper implements the server side.

    An X.509 store.

    An X.509 store is used to describe a context in which to verify a
    certificate. A description of a context may include a set of certificates
    to trust, a set of certificate revocation lists, verification flags and
    more.

    An X.509 store, being only a description, cannot be used by itself to
    verify a certificate. To carry out the actual verification process, see

        if it cannot be determined.

        Throw ValueError if package is not installed.
        uCheck package origin.

        Return True if the package is a genuine distro package, or False if it
        comes from a third-party source.

        Throw ValueError if package does not exist.
        uReturn the architecture of a package.

        This might differ on multiarch architectures (e. g. an i386 Firefox
        package on a x86_64 system)
        uReturn list of files shipped by a package.

        Throw ValueError if package does not exist.
        uReturn list of all modified files of a package.uReturn modified configuration files of a package.

        Return a file name -> file contents map of all configuration files of
        package. Please note that apport.hookutils.attach_conffiles() is the
        official user-facing API for this, which will ask for confirmation and
        allows filtering.
        uReturn the package a file belongs to.

        Return None if the file is not shipped by any package.

        If uninstalled is True, this will also find files of uninstalled
        packages; this is very expensive, though, and needs network access and
        lots of CPU and I/O resources. In this case, map_cachedir can be set to
        an existing directory which will be used to permanently store the
        downloaded maps. If it is not set, a temporary directory will be used.
        Also, release and arch can be set to a foreign release/architecture
        instead of the one from the current system.
        uReturn the architecture of the system.

        This should use the notation of the particular distribution.
        uExplicitly set a distribution mirror URL.

        This might be called for operations that need to fetch distribution
        files/packages from the network.

        By default, the mirror will be read from the system configuration
        files.
        uDownload a source package and unpack it into dir..

        dir should exist and be empty.

        This also has to care about applying patches etc., so that dir will
        eventually contain the actually compiled source.

        If version is given, this particular version will be retrieved.
        Otherwise this will fetch the latest available version.

        Return the directory that contains the actual source root directory
        (which might be a subdirectory of dir). Return None if the source is
        not available.
        uCompare two package versions.

        Return -1 for ver < ver2, 0 for ver1 == ver2, and 1 for ver1 > ver2.
        aconfigurationa__enter__a__exit__areadTnnnareasearchu^\s*enabled\s*=\s*0\s*$aconfwMuReturn whether Apport should generate crash reports.

        Signal crashes are controlled by /proc/sys/kernel/core_pattern, but
        some init script needs to set that value based on a configuration file.
        This also determines whether Apport generates reports for Python,
        package, or kernel crashes.

        Implementations should parse the configuration file which controls
        Apport (such as /etc/default/apport in Debian/Ubuntu).
        uReturn the actual Linux kernel package name.

        This is used when the user reports a bug against the "linux" package.
        uInstall packages into a sandbox (for apport-retrace).

        In order to work without any special permissions and without touching
        the running system, this should only download and unpack packages into
        the given root directory, not install them into the system.

        configdir points to a directory with by-release configuration files for
        the packaging system; this is completely dependent on the backend
        implementation, the only assumption is that this looks into
        configdir/release/, so that you can use retracing for multiple
        DistroReleases. As a special case, if configdir is None, it uses the
        current system configuration, and "release" is ignored.

        release is the value of the report's 'DistroRelease' field.

        packages is a list of ('packagename', 'version') tuples. If the version
        is None, it should install the most current available version.

        If cache_dir is given, then the downloaded packages will be stored
        there, to speed up subsequent retraces.

        If permanent_rootdir is True, then the sandbox created from the
        downloaded packages will be reused, to speed up subsequent retraces.

        If architecture is given, the sandbox will be created with packages of
        the given architecture (as specified in a report's "Architecture"
        field). If not given it defaults to the host system's architecture.

        If origins is given, the sandbox will be created with apt data sources
        for foreign origins.

        If install_deps is True, then the dependencies of packages will also
        be installed.

        Return a string with outdated packages, or None if all packages were
        installed.

        If something is wrong with the environment (invalid configuration,
        package servers down, etc.), this should raise a SystemError with a
        meaningful error message.
        uReturn known package names which match given glob.apackage_name_globTw*aselfais_distro_packageaget_versionuReturn a valid package name which is not installed.

        This is only used in the test suite. The default implementation should
        work, but might be slow for your backend, so you might want to
        reimplement this.

        If uninstalled is True, this will also find files of uninstalled

        lots of CPU and I/O resources. In this case, map_cachedir can be set to
        an existing directory which will be used to permanently store the
        downloaded maps. If it is not set, a temporary directory will be used.
        Also, release and arch can be set to a foreign release/architecture

        This also has to care about applying patches etc., so that dir will
        eventually contain the actually compiled source. dir needs to exist and
        should be empty.

        If version is given, this particular version will be retrieved.
        Otherwise this will fetch the latest available version.

        If sandbox is given, it calls apt-get source in that sandbox, otherwise
        it uses the system apt configuration.

        If apt_update is True, it will call apt-get update before apt-get
        source. This is mostly necessary for freshly created sandboxes.

        Return the directory that contains the actual source root directory
        (which might be a subdirectory of dir). Return None if the source is

uapt fetcher did not fetch these packages: w a_save_virtual_mappinguInstall packages into a sandbox (for apport-retrace).

        In order to work without any special permissions and without touching
        the running system, this should only download and unpack packages into
        the given root directory, not install them into the system.

        configdir points to a directory with by-release configuration files for
        the packaging system; this is completely dependent on the backend
        implementation, the only assumption is that this looks into
        configdir/release/, so that you can use retracing for multiple
        DistroReleases. As a special case, if configdir is None, it uses the
        current system configuration, and "release" is ignored.

        release is the value of the report's 'DistroRelease' field.

        packages is a list of ('packagename', 'version') tuples. If the version
        is None, it should install the most current available version.

        If cache_dir is given, then the downloaded packages will be stored
        there, to speed up subsequent retraces.

        If permanent_rootdir is True, then the sandbox created from the
        downloaded packages will be reused, to speed up subsequent retraces.

        If architecture is given, the sandbox will be created with packages of
        the given architecture (as specified in a report's "Architecture"
        field). If not given it defaults to the host system's architecture.

        If origins is given, the sandbox will be created with apt data sources
        for foreign origins.

        If install_deps is True, then the dependencies of packages will also
        be installed.

        Return a string with outdated packages, or an empty string if all
        packages were installed.

        If something is wrong with the environment (invalid configuration,
        package servers down, etc.), this should raise a SystemError with a
        meaningful error message.
        afnmatchafilteruReturn known package names which match given glob.LadpkgTOinputupackage does not existuCall dpkg with given arguments and return output, or return None on

        This is suitable for identifying duplicates.

        For signal crashes this the concatenation of ExecutablePath, Signal
        number, and StacktraceTop function names, separated by a colon. If
        StacktraceTop has unknown functions or the report lacks any of those
        fields, return None. In this case, you can use
        crash_signature_addresses() to get a less precise duplicate signature
        based on addresses instead of symbol names.

        For assertion failures, it is the concatenation of ExecutablePath
        and assertion message, separated by colons.

        For Python crashes, this concatenates the ExecutablePath, exception
        name, and Traceback function names, again separated by a colon.

        For suspend/resume failures, this concatenates whether it was a suspend
        or resume failure with the hardware identifier and the BIOS version, if
        it exists.

        This should be used if crash_signature() fails, i. e. Stacktrace does
        not have enough symbols.

        This approach only uses addresses in the stack trace and does not rely
        on symbol resolution. As we can't unwind these stack traces, we cannot
        limit them to the top five frames and thus will end up with several or
        many different signatures for a particular crash. But these can be
        computed and synchronously checked with a crash database at the client
        side, which avoids having to upload and process the full report. So on
        the server-side crash database we will only have to deal with all the
        equivalence classes (i. e. same crash producing a number of possible
        signatures) instead of every single report.

        Return None when signature cannot be determined.

        resolve function names, but taking the raw addresses also is not
        suitable due to ASLR. But the offsets within a library should be
        constant between crashes (assuming the same version of all libraries).

        You can specify either an :class:`apt.progress.base.AcquireProgress()`

        existing :class:`apt_pkg.Acquire` object for the parameter *fetcher*.

        The return value of the function is undefined. If an error occurred,
        an exception of type :class:`FetchFailedException` or
        :class:`FetchCancelledException` is raised.

        The keyword-only parameter *allow_unauthenticated* specifies whether
        to allow unauthenticated downloads. If not specified, it defaults to
        the configuration option `APT::Get::AllowUnauthenticated`.

        least one version providing the virtual package. Otherwise,
        return only those packages where the candidate version
        provides the virtual package.

        If 'include_nonvirtual' is True then it will search for all
        packages providing pkgname, even if pkgname is not itself
        a virtual pkg.

        The second parameter, *install_progress*, is a

        The keyword-only parameter *allow_unauthenticated* specifies whether

        uConnect to a signal.

        The callback will be passed the cache as an argument, and
        any arguments passed to this function. Make sure that, if you
        pass a method of a class as your callback, your class does not
        contain a reference to the cache.

        Cyclic references to the cache can cause issues if the Cache object
        is replaced by a new one, because the cache keeps a lot of objects and
        tens of open file descriptors.

        aActionGroupuReturn an `ActionGroup` object for the current cache.

        Action groups can be used to speedup actions. The action group is
        active as soon as it is created, and disabled when the object is
        deleted or when release() is called.

        You can use the action group as a context manager, this is the
        recommended way::

            with cache.actiongroup():
                for package in my_selected_packages:
                    package.mark_install()

        This way, the action group is automatically released as soon as the
        with statement block is left. It also has the benefit of making it
        clear which parts of the code run with a action group and which
        don't.

    The APT cache file contains a hash table mapping names of binary
    packages to their metadata. A Cache object is the in-core
    representation of the same. It provides access to APTs idea of the
    list of available packages.

    The cache can be used like a mapping from package names to Package
    objects (although only getting items is supported).

    Keyword arguments:
    progress -- a OpProgress object,
    rootdir  -- an alternative root directory. if that is given the system
    sources.list and system lists/files are not read, only file relative
    to the given rootdir,
    memonly  -- build the cache in memory only.


    .. versionchanged:: 1.0

        The cache now supports package names with special architecture
        qualifiers such as :all and :native. It does not export them
        in :meth:`keys()`, though, to keep :meth:`keys()` a unique set.

    The optional parameter `progress` is a CdromProgress() subclass, which will

    object will be used.

    The optional parameter `mountpoint` may be used to specify an alternative
    mountpoint.

    If the optional parameter `nomount` is True, the cdroms will not be
    mounted. This is the default behaviour.

        This method behaves like Python 2's cmp builtin and returns an integer
        according to the outcome.  The return value is negative in case of
        self < other, zero if self == other and positive if self > other.

        The comparison includes the package name and architecture if other is
        an apt.Version object.  If other isn't an apt.Version object it'll be
        assumed that other is a version string (without package name/arch).

        installed automatically.  This is the default.

        If *fromUser* is ``True``, this package will not be marked as
        automatically installed. This is the default. Set it to False if you
        want to be able to automatically remove the package at a later stage

    uOrigin.__init__uOrigin.__repr__uRecord in a Packages file

    Represent a record as stored in a Packages file. You can use this like
    a dictionary mapping the field names of the record to their values::

        >>> record = Record("Package: python-apt\nVersion: 0.8.0\n\n")
        >>> record["Package"]
        'python-apt'
        >>> record["Version"]
        '0.8.0'

    For example, to get the tasks of a package from a cache, you could do::

        package.candidate.record["Tasks"].split()

    Of course, you can also use the :attr:`Version.tasks` property.

    This class can be used like a dictionary, where version strings are the
    keys. It can also be used as a sequence, where integers are the keys.

    You can also convert this to a dictionary or a list, using the usual way
    of dict(version_list) or list(version_list). This is useful if you need
    to access the version objects multiple times, because they do not have to
    be recreated this way.

    Examples ('package.versions' being a version list):
        '0.7.92' in package.versions # Check whether 0.7.92 is a valid version.
        package.versions[0] # Return first version or raise IndexError
        package.versions[0:2] # Return a new VersionList for objects 0-2
        package.versions['0.7.92'] # Return version 0.7.92 or raise KeyError
        package.versions.keys() # All keys, as strings.

    lets you mark the package for installation, check if it is installed, and
    much more.

        uBase classes for progress reporting.

Custom progress classes should inherit from these classes. They can also be
used as dummy progress classes which simply do nothing.
a__doc__u/usr/lib/python3/dist-packages/apt/progress/base.pya__file__a__spec__aoriginahas_locationa__cached__aprint_functionasysaOptionalaUnionaioLaAcquireProgressaCdromProgressaInstallProgressaOpProgressa__all__TOobjectametaclassa__prepare__aAcquireProgressa__getitem__u%s.__prepare__() must return a mapping, not %sa__name__u<metaclass>uapt.progress.basea__module__uMonitor object for downloads controlled by the Acquire class.

    This is an mostly abstract class. You should subclass it and implement the
    methods to get something useful.
    a__qualname__uInvoked when an item is successfully and completely fetched.adoneuAcquireProgress.doneuInvoked when an item could not be fetched.afailuAcquireProgress.failuInvoked when some of the item's data is fetched.afetchuAcquireProgress.fetchuInvoked when an item is confirmed to be up-to-date.

        Invoked when an item is confirmed to be up-to-date. For instance,
        when an HTTP download is informed that the file on the server was
        not modified.
        aims_hituAcquireProgress.ims_hituPrompt the user to change the inserted removable media.

        The parameter 'media' decribes the name of the media type that
        should be changed, whereas the parameter 'drive' should be the
        identifying name of the drive whose media should be changed.

        This method should not return until the user has confirmed to the user
        interface that the media change is complete. It must return True if
        the user confirms the media change, or False to cancel it.
        amedia_changeuAcquireProgress.media_changeuPeriodically invoked while the Acquire process is underway.

        This method gets invoked while the Acquire progress given by the
        parameter 'owner' is underway. It should display information about
        the current state.

        This function returns a boolean value indicating whether the
        acquisition should be continued (True) or cancelled (False).
        apulseuAcquireProgress.pulseastartuAcquireProgress.startuInvoked when the Acquire process stops running.astopuAcquireProgress.stopa__orig_bases__aCdromProgressuBase class for reporting the progress of adding a cdrom.

    Can be used with apt_pkg.Cdrom to produce an utility like apt-cdrom. The
    attribute 'total_steps' defines the total number of steps and can be used
    in update() to display the current progress.
    atotal_stepsuAsk for the name of the cdrom.

        If a name has been provided, return it. Otherwise, return None to
        cancel the operation.
        aask_cdrom_nameuCdromProgress.ask_cdrom_nameuAsk for the CD-ROM to be changed.

        Return True once the cdrom has been changed or False to cancel the
        operation.
        achange_cdromuCdromProgress.change_cdromuPeriodically invoked to update the interface.

        The string 'text' defines the text which should be displayed. The
        integer 'current' defines the number of completed steps.
        aupdateuCdromProgress.updateaInstallProgressuClass to report the progress of installing packages.TlZf�������?ua__init__uInstallProgress.__init__u(Abstract) Start update.astart_updateuInstallProgress.start_updateu(Abstract) Called when update has finished.afinish_updateuInstallProgress.finish_updatea__enter__uInstallProgress.__enter__a__exit__uInstallProgress.__exit__u(Abstract) Called when a error is detected during the install.uInstallProgress.erroru(Abstract) Called when a conffile question from dpkg is detected.uInstallProgress.conffileu(Abstract) Called when the APT status changed.uInstallProgress.status_changeu(Abstract) Called when the dpkg status changed.uInstallProgress.dpkg_status_changeu(Abstract) Sent just before a processing stage starts.

        The parameter 'stage' is one of "upgrade", "install"
        (both sent before unpacking), "configure", "trigproc", "remove",
        "purge". This method is used for dpkg only.
        uInstallProgress.processingarunuInstallProgress.runuInstallProgress.forkuInstallProgress.update_interfaceuInstallProgress.wait_childaOpProgressuMonitor objects for operations.

        We define three types of bytes:
        alphabet: english alphabets [a-zA-Z]
        international: international characters [-ÿ]
        marker: everything else [^a-zA-Z-ÿ]

        The input buffer can be thought to contain a series of words delimited
        by markers. This function works to filter all words that contain at
        least one international character. All contiguous sequences of markers
        are replaced by a single space ascii character.

        This filter applies to all scripts which do not use English characters.
        lld>d<aprevain_tagTd u
        Returns a copy of ``buf`` that retains only the sequences of English
        alphabet and high byte characters that are not between <> characters.
        Also retains English alphabet and high byte characters immediately
        before occurrences of >.

        This filter can be applied to all scripts which contain both English
        characters and extended ASCII characters, but is currently only used by
        ``Latin1Prober``.

    A state machine to verify a byte sequence for a particular encoding. For
    each byte the detector receives, it will feed that byte to every active
    state machine available, one byte at a time. The state machine changes its
    state based on its previous state and the byte it receives. There are 3
    states in a state machine that are of interest to an auto-detector:

    START state: This is the state to start with, or a legal byte sequence
                 (i.e. a valid code point) for character has been identified.

    ME state:  This indicates that the state machine identified a byte sequence
               that is specific to the charset it is designed for and that
               there is no other possible encoding which can contain this byte
               sequence. This will to lead to an immediate positive answer for
               the detector.

    ERROR state: This indicates the state machine identified an illegal byte
                 sequence for that encoding. This will lead to an immediate
                 negative answer for this encoding. Detector will exclude this
                 encoding from consideration from here on.

        Takes a chunk of a document and feeds it through all of the relevant
        charset probers.

        After calling ``feed``, you can check the value of the ``done``
        attribute to see if you need to continue feeding the
        ``UniversalDetector`` more data, or if it has made a prediction
        (in the ``result`` attribute).

        .. note::
           You should always call ``close`` when you're done feeding in your
           document if ``done`` is not already ``True``.

    The ``UniversalDetector`` class underlies the ``chardet.detect`` function
    and coordinates all of the different charset probers.

    To get a ``dict`` containing an encoding and its confidence, you can simply
    run:

    .. code::

            u = UniversalDetector()
            u.feed(some_bytes)
            u.close()
            detected = u.result

        Converts a python integer to a BIGNUM. The returned BIGNUM will not
        be garbage collected (to support adding them to structs that take
        ownership of the object). Be sure to register it for GC if it will
        be discarded after use.

        This method creates a bytearray, which we copy data into (hopefully
        also from a mutable buffer that can be dynamically erased!), and then
        zero when we're done.
        a_zero_datauBackend._zeroed_bytearrayarangeu
        This method takes bytes, which can be a bytestring or a mutable
        buffer like a bytearray, and yields a null-terminated version of that
        data. This is required because PKCS12_parse doesn't take a length with
        its password char * and ffi.from_buffer doesn't provide null
        termination. So, to support zeroing the data via bytearray we
        need to build this ridiculous construct that copies the memory, but
        zeroes it after use.

        An X.509 name is a two-level structure: a list of sets of attributes.
        Each list element is separated by ',' and within each list element, set
        elements are separated by '+'. The latter is almost never used in
        real world certificates.

    Return information about the current OS distribution as a tuple
    ``(id_name, version, codename)`` with items as follows:

    * ``id_name``:  If *full_distribution_name* is false, the result of
      :func:`distro.id`. Otherwise, the result of :func:`distro.name`.

    * ``version``:  The result of :func:`distro.version`.

    * ``codename``:  The result of :func:`distro.codename`.

    The interface of this function is compatible with the original
    :py:func:`platform.linux_distribution` function, supporting a subset of
    its parameters.

    The data it returns may not exactly be the same, because it uses more data
    sources than the original function, and that may lead to different data if
    the OS distribution is not consistent across multiple data sources it
    provides (there are indeed such distributions ...).

    Another reason for differences is the fact that the :func:`distro.id`
    method normalizes the distro ID string to a reliable machine-readable value
    for a number of popular OS distributions.
    aidu
    Return the distro ID of the current distribution, as a
    machine-readable string.

    For a number of OS distributions, the returned distro ID value is
    *reliable*, in the sense that it is documented and that it does not change
    across releases of the distribution.

    This package maintains the following reliable distro ID values:

    ==============  =========================================

    ==============  =========================================

    If you have a need to get distros for reliable IDs added into this set,
    or if you find that the :func:`distro.id` function returns a different
    distro ID for one of the listed distros, please create an issue in the
    `distro issue tracker`_.

    **Lookup hierarchy and transformations:**

    First, the ID is obtained from the following sources, in the specified
    order. The first available and non-empty value is used:

    * the value of the "ID" attribute of the os-release file,

    * the value of the "Distributor ID" attribute returned by the lsb_release
      command,

    * the first part of the file name of the distro release file,

    The so determined ID value then passes the following transformations,
    before it is returned by this method:

    * it is translated to lower case,

    * blanks (which should not be there anyway) are translated to underscores,

    * a normalization of the ID is performed, based upon
      `normalization tables`_. The purpose of this normalization is to ensure
      that the ID is as reliable as possible, even across incompatible changes
      in the OS distributions. A common reason for an incompatible change is
      the addition of an os-release file, or the addition of the lsb_release
      command, with ID values that differ from what was previously determined
      from the distro release file name.
    anameu
    Return the name of the current OS distribution, as a human-readable
    string.

    If *pretty* is false, the name is returned without version or codename.
    (e.g. "CentOS Linux")

    If *pretty* is true, the version and codename are appended.
    (e.g. "CentOS Linux 7.1.1503 (Core)")

    **Lookup hierarchy:**

    The name is obtained from the following sources, in the specified order.
    The first available and non-empty value is used:

    * If *pretty* is false:

      - the value of the "NAME" attribute of the os-release file,

      - the value of the "Distributor ID" attribute returned by the lsb_release
        command,

      - the value of the "<name>" field of the distro release file.

    * If *pretty* is true:

      - the value of the "PRETTY_NAME" attribute of the os-release file,

      - the value of the "Description" attribute returned by the lsb_release
        command,

      - the value of the "<name>" field of the distro release file, appended
        with the value of the pretty version ("<version_id>" and "<codename>"
        fields) of the distro release file, if available.
    aversionu
    Return the version of the current OS distribution, as a human-readable
    string.

    If *pretty* is false, the version is returned without codename (e.g.
    "7.0").

    If *pretty* is true, the codename in parenthesis is appended, if the
    codename is non-empty (e.g. "7.0 (Maipo)").

    Some distributions provide version numbers with different precisions in
    the different sources of distribution information. Examining the different
    sources in a fixed priority order does not always yield the most precise
    version (e.g. for Debian 8.2, or CentOS 7.1).

    The *best* parameter can be used to control the approach for the returned
    version:

    If *best* is false, the first non-empty version number in priority order of
    the examined sources is returned.

    If *best* is true, the most precise version number out of all examined
    sources is returned.

    **Lookup hierarchy:**

    In all cases, the version number is obtained from the following sources.
    If *best* is false, this order represents the priority order:

    * the value of the "VERSION_ID" attribute of the os-release file,
    * the value of the "Release" attribute returned by the lsb_release
      command,
    * the version number parsed from the "<version_id>" field of the first line
      of the distro release file,
    * the version number parsed from the "PRETTY_NAME" attribute of the
      os-release file, if it follows the format of the distro release files.
    * the version number parsed from the "Description" attribute returned by
      the lsb_release command, if it follows the format of the distro release
      files.
    aversion_partsu
    Return the version of the current OS distribution as a tuple
    ``(major, minor, build_number)`` with items as follows:

    * ``major``:  The result of :func:`distro.major_version`.

    * ``minor``:  The result of :func:`distro.minor_version`.

    * ``build_number``:  The result of :func:`distro.build_number`.

    For a description of the *best* parameter, see the :func:`distro.version`
    method.
    amajor_versionu
    Return the major version of the current OS distribution, as a string,
    if provided.
    Otherwise, the empty string is returned. The major version is the first
    part of the dot-separated version string.

    For a description of the *best* parameter, see the :func:`distro.version`
    method.
    aminor_versionu
    Return the minor version of the current OS distribution, as a string,
    if provided.
    Otherwise, the empty string is returned. The minor version is the second
    part of the dot-separated version string.

    For a description of the *best* parameter, see the :func:`distro.version`
    method.
    abuild_numberu
    Return the build number of the current OS distribution, as a string,
    if provided.
    Otherwise, the empty string is returned. The build number is the third part
    of the dot-separated version string.

    For a description of the *best* parameter, see the :func:`distro.version`
    method.
    alikeu
    Return a space-separated list of distro IDs of distributions that are
    closely related to the current OS distribution in regards to packaging
    and programming interfaces, for example distributions the current
    distribution is a derivative from.

    **Lookup hierarchy:**

    This information item is only provided by the os-release file.
    For details, see the description of the "ID_LIKE" attribute in the
    `os-release man page
    <http://www.freedesktop.org/software/systemd/man/os-release.html>`_.
    acodenameu
    Return the codename for the release of the current OS distribution,
    as a string.

    If the distribution does not have a codename, an empty string is returned.

    Note that the returned codename is not always really a codename. For
    example, openSUSE returns "x86_64". This function does not handle such
    cases in any special way and just returns the string it finds, if any.

    **Lookup hierarchy:**

    * the codename within the "VERSION" attribute of the os-release file, if
      provided,

    * the value of the "Codename" attribute returned by the lsb_release
      command,

    * the value of the "<codename>" field of the distro release file.
    ainfou
    Return certain machine-readable information items about the current OS
    distribution in a dictionary, as shown in the following example:

    .. sourcecode:: python

        {
            'id': 'rhel',
            'version': '7.0',
            'version_parts': {
                'major': '7',
                'minor': '0',
                'build_number': ''
            },
            'like': 'fedora',
            'codename': 'Maipo'
        }

    The dictionary structure and keys are always the same, regardless of which
    information items are available in the underlying data sources. The values
    for the various keys are as follows:

    * ``id``:  The result of :func:`distro.id`.

    * ``version``:  The result of :func:`distro.version`.

    * ``version_parts -> major``:  The result of :func:`distro.major_version`.

    * ``version_parts -> minor``:  The result of :func:`distro.minor_version`.

    * ``version_parts -> build_number``:  The result of
      :func:`distro.build_number`.

    * ``like``:  The result of :func:`distro.like`.

    * ``codename``:  The result of :func:`distro.codename`.

    For a description of the *pretty* and *best* parameters, see the
    :func:`distro.version` method.

    a__name__a_fnamea_fucall {} on an instanceajoina_UNIXCONFDIRa_OS_RELEASE_BASENAMEaos_release_fileuadistro_release_fileainclude_lsbainclude_unameu
        The initialization method of this class gathers information from the
        available data sources, and stores that in private instance attributes.
        Subsequent access to the information items uses these private instance
        attributes, so that the data sources are read only once.

        Parameters:

        * ``include_lsb`` (bool): Controls whether the
          `lsb_release command output`_ is included as a data source.

          If the lsb_release command is not available in the program execution
          path, the data source for the lsb_release command will be empty.

        * ``os_release_file`` (string): The path name of the
          `os-release file`_ that is to be used as a data source.

          An empty string (the default) will cause the default path name to
          be used (see `os-release file`_ for details).

          If the specified or defaulted os-release file does not exist, the
          data source for the os-release file will be empty.

        * ``distro_release_file`` (string): The path name of the
          `distro release file`_ that is to be used as a data source.

          An empty string (the default) will cause a default search algorithm
          to be used (see `distro release file`_ for details).

          If the specified distro release file does not exist, or if no default
          distro release file can be found, the data source for the distro
          release file will be empty.

        * ``include_name`` (bool): Controls whether uname command output is
          included as a data source. If the uname command is not available in
          the program execution path the data source for the uname command will
          be empty.

        Public instance attributes:

        * ``os_release_file`` (string): The path name of the
          `os-release file`_ that is actually used as a data source. The
          empty string if no distro release file is used as a data source.

        * ``distro_release_file`` (string): The path name of the
          `distro release file`_ that is actually used as a data source. The
          empty string if no distro release file is used as a data source.

        * ``include_lsb`` (bool): The result of the ``include_lsb`` parameter.
          This controls whether the lsb information will be loaded.

        * ``include_uname`` (bool): The result of the ``include_uname``
          parameter. This controls whether the uname information will
          be loaded.

        Raises:

        * :py:exc:`IOError`: Some I/O issue with an os-release file or distro
          release file.

        * :py:exc:`subprocess.CalledProcessError`: The lsb_release command had
          some issue (other than not being available in the program execution
          path).

        * :py:exc:`UnicodeError`: A data source has unexpected characters or

The ``distro`` package (``distro`` stands for Linux Distribution) provides
information about the Linux distribution it runs on, such as a reliable
machine-readable distro ID, or version information.

It is the recommended replacement for Python's original
:py:func:`platform.linux_distribution` function, but it provides much more
functionality. An alternative implementation became necessary because Python
3.5 deprecated this function, and Python 3.8 will remove it altogether.
Its predecessor function :py:func:`platform.dist` was already
deprecated since Python 2.6 and will also be removed in Python 3.8.
Still, there are many cases in which access to OS distribution information
is needed. See `Python issue 1322 <https://bugs.python.org/issue1322>`_ for
more information.

    Provides information about a OS distribution.

    This package creates a private module-global instance of this class with
    default initialization arguments, that is used by the
    `consolidated accessor functions`_ and `single source accessor functions`_.
    By using default initialization arguments, that module-global instance
    returns data about the current OS distribution (i.e. the distro this
    package runs on).

    Normally, it is not necessary to create additional instances of this class.
    However, in situations where control is needed over the exact data sources
    that are used, instances of this class can be created with a specific
    distro release file, or a specific os-release file, or without invoking the
    lsb_release command.

    We don't handle the following:

    1. Cache-Control: max-stale
    2. Age: headers are not used in the calculations.

    Not that this algorithm is simpler than you might think
    because we are operating as a private (non-shared) cache.
    This lets us ignore 's-maxage'. We can also ignore
    'proxy-invalidate' since we aren't a proxy.
    We will never return a stale document as
    fresh as a design decision, and thus the non-implementation
    of 'max-stale'. This also lets us safely ignore 'must-revalidate'
    since we operate as if every server has sent 'must-revalidate'.
    Since we are private we get to ignore both 'public' and
    'private' parameters. We also ignore 'no-transform' since
    we don't do any transformations.
    The 'no-store' parameter is handled at a higher level.
    So the only Cache-Control parameters we look at are:

    no-cache
    only-if-cached
    max-age
    min-fresh

          proxy_rdns: If True (default), DNS queries will not be performed
          locally, and instead, handed to the proxy to resolve.  This is useful
          if the network does not allow resolution of non-local names. In

        `proxy_info` may be:
          - a callable that takes the http scheme ('http' or 'https') and
            returns a ProxyInfo instance per request. By default, uses
            proxy_info_from_environment.
          - a ProxyInfo instance (static proxy config).
          - None (proxy disabled).

        ca_certs is the path of a file containing root CA certificates for SSL
        server certificate validation.  By default, a CA cert file bundled with
        httplib2 is used.

        If disable_ssl_certificate_validation is true, SSL cert validation will
        not be performed.

The 'uri' is the URI of the HTTP resource and can begin
with either 'http' or 'https'. The value of 'uri' must be an absolute URI.

The 'method' is the HTTP method to perform, such as GET, POST, DELETE, etc.
There is no restriction on the methods allowed.

The 'body' is the entity body to be sent with the request. It is a string
object.

Any extra headers that are to be sent with the request should be provided in the
'headers' dictionary.

The maximum number of redirect to follow before raising an
exception is 'redirections. The default is 5.

The return value is a tuple of (response, content), the first
being and instance of the 'Response' class, the second being
a string that contains the response entity body.

        Sets the proxy to be used.
        proxytype -    The type of the proxy to be used. Three types
                are supported: PROXY_TYPE_SOCKS4 (including socks4a),
                PROXY_TYPE_SOCKS5 and PROXY_TYPE_HTTP
        addr -        The address of the server (IP or DNS).
        port -        The port of the server. Defaults to 1080 for SOCKS
                servers and 8080 for HTTP proxy servers.
        rdns -        Should DNS queries be preformed on the remote side
                (rather than the local side). The default is True.
                Note: This has no effect with SOCKS4 servers.
        username -    Username to authenticate with to the server.
                The default is no authentication.
        password -    Password to authenticate with to the server.
                Only relevant when username is also provided.
        headers -     Additional or modified headers for the proxy connect
        request.

Given a list of integers, made up of (hopefully) a small number of long runs

        indicating the priority of the backend relative to all other backends.
        The priority need not be static -- it may (and should) vary based
        attributes of the environment in which is runs (platform, available
        packages, etc.).

        A higher number indicates a higher priority. The priority should raise
        a RuntimeError with a message indicating the underlying cause if the
        backend is not suitable for the current environment.

        As a rule of thumb, a priority between zero but less than one is
        suitable, but a priority of one or greater is recommended.

    An implementation of a property callable on a class. Used to decorate a
    classmethod but to then treat it like a property.

    Example:

    >>> class MyClass:
    ...    @ClassProperty
    ...    @classmethod
    ...    def skillz(cls):
    ...        return cls.__name__.startswith('My')
    >>> MyClass.skillz
    True
    >>> class YourClass(MyClass): pass
    >>> YourClass.skillz
    False
    a__qualname__uClassProperty.__get__a__orig_bases__TTaNonDataPropertyTuMuch like the property builtin, but only implements __get__,
    making it a non-data property, and can be subsequently reset.

            wants to use launchpadlib. This is used in conjunction
            with a desktop-wide integration.

            If you specify this argument, your values for
            consumer_name and allow_access_levels are ignored.

        :param consumer_name: The OAuth consumer name, for an
            application that wants its own point of integration into
            Launchpad. In almost all cases, you want to specify
            application_name instead and do a desktop-wide
            integration. The exception is when you're integrating a
            third-party website into Launchpad.

        :param allow_access_levels: A list of the Launchpad access
            levels to present to the user. ('READ_PUBLIC' and so on.)

        If the credential store runs into a problem storing the

        be invoked. The callback will not be invoked if there's a
        problem authorizing the credentials.

        :param credentials: A `Credentials` object. If the end-user
            authorizes these credentials, this object will have its
            .access_token property set.

        :param credential_store: A `CredentialStore` object. If the
            end-user authorizes the credentials, they will be
            persisted locally using this object.

        :return: If the credentials are successfully authorized, the
            return value is the `Credentials` object originally passed
            in. Otherwise the return value is None.

        Your subclass must implement this method: it has no default
        implementation.

        Because an access token may expire or be revoked in the middle
        of a session, this method may be called at arbitrary points in
        a launchpadlib session, or even multiple times during a single
        session (with a different request token each time).

        In most cases, however, this method will be called at the
        beginning of a launchpadlib session, or not at all.

        reused.

        You can customize this behavior in three ways:

        1. Pass in a filename to `credentials_file`. The end-user's
           credential will be written to that file, and on subsequent
           runs read from that file.

        2. Subclass `CredentialStore` and pass in an instance of the
           subclass as `credential_store`. This lets you change how
           the end-user's credential is stored and retrieved locally.

        3. Subclass `RequestTokenAuthorizationEngine` and pass in an
           instance of the subclass as `authorization_engine`. This
           lets you change change what happens when the end-user needs
           to authorize the Launchpad credential.

        :param application_name: The application name. This is *not*
            the OAuth consumer name. Unless a consumer_name is also
            provided, the OAuth consumer will be a system-wide
            consumer representing the end-user's computer as a whole.
        :type application_name: string

        :param launchpadlib_dir: The directory used to store cached
           data obtained from Launchpad. The cache is shared by all

        :param authorization_engine: A strategy for getting the
            end-user to authorize an OAuth request token, for
            exchanging the request token for an access token, and for
            storing the access token locally so that it can be
            reused. By default, launchpadlib will open the end-user's
            web browser to have them authorize the request token.

            `authorization_engine` any value for this argument will be
            ignored. This argument will also be ignored unless you
            also specify `consumer_name`.

            this user's OAuth access token.

        :param version: The version of the Launchpad web service to use.

        :param consumer_name: The consumer name, as appropriate for
            the `Consumer` constructor. You probably don't want to
            provide this, since providing it will prevent you from
            taking advantage of desktop-wide integration.
        :type consumer_name: string

        :param credential_save_failed: a callback that is called upon
           a failure to save the credentials locally. This argument is
           used to construct the default `credential_store`, so if
           you pass in your own `credential_store` any value for
           this argument will be ignored.
        :type credential_save_failed: A callable

        :param credential_store: A strategy for storing an OAuth
            access token locally. By default, tokens are stored in the

            provided, then tokens are stored unencrypted in that file.

        To discourage situations where a lazr.restful client fetches
        all of an enormous list, all collection slices must have a
        definitive end point. For performance reasons, all collection
        slices must be indexed from the start of the list rather than
        the end.

        to the corresponding entry resource. So each of these

    This class transforms keys to lowercase before doing a lookup on
    the underlying dictionary. That way wadllib can pass in the

    aSystemRandomuuGenerates a non-guessable OAuth token

    OAuth (1 and 2) does not specify the format of tokens except that they
    should be strings of random characters. Tokens should not be guessable
    and entropy when generating the random characters is important. Which is
    why SystemRandom is used instead of the default random.choice method.

        Signs an HTTP request with the specified parts.

        Returns a 3-tuple of the signed request's URI, headers, and body.
        Note that http_method is not returned as it is unaffected by the OAuth
        signing process. Also worth noting is that duplicate parameters
        will be included in the signature, regardless of where they are
        specified (query, body).

        The body argument may be a dict, a list of 2-tuples, or a formencoded
        string. The Content-Type header must be 'application/x-www-form-urlencoded'
        if it is present.

        If the body argument is not one of the above, it will be returned
        verbatim as it is unaffected by the OAuth signing process. Attempting to
        sign a request with non-formencoded data using the OAuth body signature
        type is invalid and will raise an exception.

        If the body does contain parameters, it will be returned as a properly-
        formatted formencoded string.

        Body may not be included if the http_method is either GET or HEAD as
        this changes the semantic meaning of the request.

        All string data MUST be unicode or be encoded with the same encoding
        scheme supplied to the Client constructor, default utf-8. This includes
        strings inside body dicts, for example.

    to their protected resources to a client.

    Typical use would be to have two views, one for displaying the authorization
    form and one to process said form on submission.

    The first view will want to utilize ``get_realms_and_credentials`` to fetch
    requested realms and useful client credentials, such as name and
    description, to be used when creating the authorization form.

    During form processing you can use ``create_authorization_response`` to
    validate the request, create a verifier as well as prepare the final
    redirection URI used to send the user back to the client.

        The dummy client should be associated with either a client secret,
        a rsa key or both depending on which signature methods are supported.
        Providers should make sure that

        This method must allow the use of a dummy client_key value.
        Fetching the secret using the dummy key must take the same amount of
        time as fetching a secret for a valid client::

        :param request: OAuthlib request.
        :type request: oauthlib.common.Request
        :returns: The list of default realms associated with the client.

        The list of default realms will be set during client registration and
        is outside the scope of OAuthLib.

        This method is used by

        Taget_realmsuGet realms associated with a request token.

        :param token: The request token string.
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request

        Taget_redirect_uriuGet the redirect URI associated with a request token.

        :param token: The request token string.
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request
        :returns: The redirect URI associated with the request token.

        It may be desirable to return a custom URI if the redirect is set to "oob".
        In this case, the user will be redirected to the returned URI and at that
        endpoint the verifier can be displayed.

        This method is used by

        * AuthorizationEndpoint
        Taget_rsa_keyuRetrieves a previously stored client provided RSA key.

        :param client_key: The client/consumer key.
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request
        :returns: The rsa public key as a string.

        This method must allow the use of a dummy client_key value. Fetching
        the rsa key using the dummy key must take the same amount of time
        as fetching a key for a valid client. The dummy key must also be of
        the same bit length as client keys.

        Note that the key must be returned in plaintext.

        * AccessTokenEndpoint
        * RequestTokenEndpoint
        * ResourceEndpoint
        * SignatureOnlyEndpoint
        Tainvalidate_request_tokenuInvalidates a used request token.

        :param client_key: The client/consumer key.

        :param request: OAuthlib request.
        :type request: oauthlib.common.Request

        Per `Section 2.3`__ of the spec:

        "The server MUST (...) ensure that the temporary
        credentials have not expired or been used before."

        .. _`Section 2.3`: https://tools.ietf.org/html/rfc5849#section-2.3

        This method should ensure that provided token won't validate anymore.
        It can be simply removing RequestToken from storage or setting
        specific flag that makes it invalid (note that such flag should be
        also validated during request token validation).

        This method is used by

        :returns: True or False

        Note that if the dummy client is supplied it should validate in same
        or nearly the same amount of time as a valid one.

        Ensure latency inducing tasks are mimiced even for dummy clients.
        For example, use::

            from your_datastore import Client

        :param request: OAuthlib request.
        :type request: oauthlib.common.Request
        :returns: True or False

        Per `Section 3.3`_ of the spec.

        "A nonce is a random string, uniquely generated by the client to allow
        the server to verify that a request has never been made before and
        helps prevent replay attacks when requests are made over a non-secure
        channel.  The nonce value MUST be unique across all requests with the
        same timestamp, client credentials, and token combinations."

        .. _`Section 3.3`: https://tools.ietf.org/html/rfc5849#section-3.3

        One of the first validation checks that will be made is for the validity
        of the nonce and timestamp, which are associated with a client key and
        possibly a token. If invalid then immediately fail the request
        by returning False. If the nonce/timestamp pair has been used before and
        you may just have detected a replay attack. Therefore it is an essential
        part of OAuth security that you not allow nonce/timestamp reuse.
        Note that this validation check is done before checking the validity of
        the client and token.::

           nonces_and_timestamps_database = [
              (u'foo', 1234567890, u'rannoMstrInghere', u'bar')

        Tavalidate_redirect_uriuValidates the client supplied redirection URI.

        :param client_key: The client/consumer key.
        :param redirect_uri: The URI the client which to redirect back to after
                             authorization is successful.
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request
        :returns: True or False

        It is highly recommended that OAuth providers require their clients
        to register all redirection URIs prior to using them in requests and
        register them as absolute URIs. See `CWE-601`_ for more information
        about open redirection attacks.

        By requiring registration of all redirection URIs it should be
        straightforward for the provider to verify whether the supplied
        redirect_uri is valid or not.

        Alternatively per `Section 2.1`_ of the spec:

        "If the client is unable to receive callbacks or a callback URI has
        been established via other means, the parameter value MUST be set to
        "oob" (case sensitive), to indicate an out-of-band configuration."

        This method is used by

        * RequestTokenEndpoint
        Tavalidate_requested_realmsuValidates that the client may request access to the realm.

        :param client_key: The client/consumer key.
        :param realms: The list of realms that client is requesting access to.
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request
        :returns: True or False

        This method is invoked when obtaining a request token and should
        tie a realm to the request token and after user authorization
        this realm restriction should transfer to the access token.

        This method is used by

        * RequestTokenEndpoint
        Tavalidate_realmsuValidates access to the request realm.

        :param client_key: The client/consumer key.
        :param token: A request token string.
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request
        :param uri: The URI the realms is protecting.
        :param realms: A list of realms that must have been granted to
                       the access token.
        :returns: True or False

        How providers choose to use the realm parameter is outside the OAuth
        specification but it is commonly used to restrict access to a subset
        of protected resources such as "photos".

        realms is a convenience parameter which can be used to provide
        a per view method pre-defined list of allowed realms.

        Can be as simple as::

            from your_datastore import RequestToken
            request_token = RequestToken.get(token, None)

            if not request_token:
                return False
            return set(request_token.realms).issuperset(set(realms))

        This method is used by

        * ResourceEndpoint
        Tavalidate_verifieruValidates a verification code.

        :param client_key: The client/consumer key.
        :param token: A request token string.
        :param verifier: The authorization verifier string.
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request
        :returns: True or False

        OAuth providers issue a verification code to clients after the
        resource owner authorizes access. This code is used by the client to
        obtain token credentials and the provider must verify that the
        verifier is valid and associated with the client as well as the
        resource owner.

        Verifier validation should be done in near constant time
        (to avoid verifier enumeration). To achieve this we need a
        constant time string comparison which is provided by OAuthLib
        in ``oauthlib.common.safe_string_equals``::

            from your_datastore import Verifier
            correct_verifier = Verifier.get(client_key, request_token)
            from oauthlib.common import safe_string_equals
            return safe_string_equals(verifier, correct_verifier)

        This method is used by

        * AccessTokenEndpoint
        Taverify_request_tokenuVerify that the given OAuth1 request token is valid.

        :param token: A request token string.
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request
        :returns: True or False

        This method is used only in AuthorizationEndpoint to check whether the
        oauth_token given in the authorization URL is valid or not.
        This request is not signed and thus similar ``validate_request_token``
        method can not be used.

        This method is used by

        * AuthorizationEndpoint
        Taverify_realmsuVerify authorized realms to see if they match those given to token.

        :param token: An access token string.
        :param realms: A list of realms the client attempts to access.
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request
        :returns: True or False

        This prevents the list of authorized realms sent by the client during
        the authorization step to be altered to include realms outside what
        was bound with the request token.

        Can be as simple as::

            valid_realms = self.get_realms(token)
            return all((r in valid_realms for r in realms))

        This method is used by

        * AuthorizationEndpoint
        Tasave_access_tokenuSave an OAuth1 access token.

        :param token: A dict with token credentials.
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request

        The token dictionary will at minimum include

        * ``oauth_token`` the access token string.
        * ``oauth_token_secret`` the token specific secret used in signing.
        * ``oauth_authorized_realms`` a space separated list of realms.

        Client key can be obtained from ``request.client_key``.

        The list of realms (not joined string) can be obtained from
        ``request.realm``.

        This method is used by

        * AccessTokenEndpoint
        Tasave_request_tokenuSave an OAuth1 request token.

        :param token: A dict with token credentials.
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request

        The token dictionary will at minimum include

        * ``oauth_token`` the request token string.
        * ``oauth_token_secret`` the token specific secret used in signing.
        * ``oauth_callback_confirmed`` the string ``true``.

        Client key can be obtained from ``request.client_key``.

        This method is used by

        * RequestTokenEndpoint
        Tasave_verifieruAssociate an authorization verifier with a request token.

        :param token: A request token string.
        :param verifier A dictionary containing the oauth_verifier and
                        oauth_token
        :param request: OAuthlib request.
        :type request: oauthlib.common.Request

        We need to associate verifiers with tokens for validation during the
        access token request.

        Note that unlike save_x_token token here is the ``oauth_token`` token
        string from the request token saved previously.

~~~~~~~~~~~~~~

This module is an implementation of various logic needed
for signing and checking OAuth 1.0 RFC 5849 requests.
a__doc__u/usr/lib/python3/dist-packages/oauthlib/oauth1/rfc5849/request_validator.pya__file__a__spec__aoriginahas_locationa__cached__aabsolute_importaunicode_literalsasysuTaSIGNATURE_METHODSautilsllTOobjectametaclassa__prepare__aRequestValidatora__getitem__u%s.__prepare__() must return a mapping, not %sa__name__u<metaclass>uoauthlib.oauth1.rfc5849.request_validatora__module__uA validator/datastore interaction base class for OAuth 1 providers.

    OAuth providers should inherit from RequestValidator and implement the
    methods and properties outlined below. Further details are provided in the
    documentation for each method and property.

    Methods used to check the format of input parameters. Common tests include
    length, character set, membership, range or pattern. These tests are
    referred to as `whitelisting or blacklisting`_. Whitelisting is better
    but blacklisting can be usefull to spot malicious activity.
    The following have methods a default implementation:

    - check_client_key
    - check_request_token
    - check_access_token
    - check_nonce
    - check_verifier
    - check_realms

    The methods above default to whitelist input parameters, checking that they
    are alphanumerical and between a minimum and maximum length. Rather than
    overloading the methods a few properties can be used to configure these
    methods.

    * @safe_characters -> (character set)
    * @client_key_length -> (min, max)
    * @request_token_length -> (min, max)
    * @access_token_length -> (min, max)
    * @nonce_length -> (min, max)
    * @verifier_length -> (min, max)
    * @realms -> [list, of, realms]

    Methods used to validate/invalidate input parameters. These checks usually
    hit either persistent or temporary storage such as databases or the
    filesystem. See each methods documentation for detailed usage.
    The following methods must be implemented:

    - validate_client_key
    - validate_request_token
    - validate_access_token
    - validate_timestamp_and_nonce
    - validate_redirect_uri
    - validate_requested_realms
    - validate_realms
    - validate_verifier
    - invalidate_request_token

    Methods used to retrieve sensitive information from storage.
    The following methods must be implemented:

    - get_client_secret
    - get_request_token_secret
    - get_access_token_secret
    - get_rsa_key
    - get_realms
    - get_default_realms
    - get_redirect_uri

    Methods used to save credentials.
    The following methods must be implemented:

    - save_request_token
    - save_verifier
    - save_access_token

    Methods used to verify input parameters. This methods are used during
    authorizing request token by user (AuthorizationEndpoint), to check if
    parameters are valid. During token authorization request is not signed,
    thus 'validation' methods can not be used. The following methods must be
    implemented:

    - verify_realms
    - verify_request_token

    To prevent timing attacks it is necessary to not exit early even if the
    client key or resource owner key is invalid. Instead dummy values should
    be used during the remaining verification process. It is very important
    that the dummy client and token are valid input parameters to the methods
    get_client_secret, get_rsa_key and get_(access/request)_token_secret and
    that the running time of those methods when given a dummy value remain
    equivalent to the running time when given a valid client/resource owner.
    The following properties must be implemented:

    * @dummy_client
    * @dummy_request_token
    * @dummy_access_token

    Example implementations have been provided, note that the database used is
    a simple dictionary and serves only an illustrative purpose. Use whichever
    database suits your project and how to access it is entirely up to you.
    The methods are introduced in an order which should make understanding
    their use more straightforward and as such it could be worth reading what
    follows in chronological order.

    Note that the value of "b5" is "=%3D" and not "==".  Both "c@" and
    "c2" have empty values.  While the encoding rules specified in this
    specification for the purpose of constructing the signature base
    string exclude the use of a "+" character (ASCII code 43) to
    represent an encoded space character (ASCII code 32), this practice
    is widely used in "application/x-www-form-urlencoded" encoded values,
    and MUST be properly decoded, as demonstrated by one of the "a3"
    parameter instances (the "a3" parameter is used twice in this
    request).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This module represents a direct implementation of `section 3.4`_ of the spec.

Terminology:
 * Client: software interfacing with an OAuth API
 * Server: the API provider
 * Resource Owner: the user who is granting authorization to the client

Steps for signing a request:

1. Collect parameters from the uri query, auth header, & body
2. Normalize those parameters
3. Normalize the uri
4. Pass the normalized uri, normalized parameters, and http method to
   construct the base string
5. Pass the base string and any keys needed to a signing function

        If binary is False, binary data is not loaded; the dictionary key is
        created, but its value will be an empty string. If it is True, it is
        transparently uncompressed and available as dictionary byte array values.
        If binary is 'compressed', the compressed value is retained, and the
        dictionary value will be a CompressedValue object. This is useful if
        the compressed value is still useful (to avoid recompression if the
        file needs to be written back).

        file needs to be opened in binary mode.

        If key_filter is given, only those keys will be loaded.

        Files are in RFC822 format, but with case sensitive keys.

        If only_new is True, only keys which have been added since the last
        load() are written (i. e. those returned by new_keys()).

        If a value is a string, it is written directly. Otherwise it must be a
        tuple of the form (file, encode=True, limit=None, fail_on_empty=False).
        The first argument can be a file name or a file-like object,
        which will be read and its content will become the value of this key.
        'encode' specifies whether the contents will be
        gzip compressed and base64-encoded (this defaults to True). If limit is
        set to a positive integer, the file is not attached if it's larger
        than the given limit, and the entire key will be removed. If
        fail_on_empty is True, reading zero bytes will cause an IOError.

        file needs to be opened in binary mode.

        Files are written in RFC822 format.

        The file will be temporarily chmod'ed to 000 to prevent frontends

        file must be a file-like object, not a path.  It needs to be opened in
        binary mode.

        If a value is a string or a CompressedValue, it is written directly.
        Otherwise it must be a tuple containing the source file and an optional
        boolean value (in that order); the first argument can be a file name or
        a file-like object, which will be read and its content will become the
        value of this key.  The file will be gzip compressed, unless the key
        already ends in .gz.

        attach_treshold specifies the maximum number of lines for a value to be
        included into the first inline text part. All bigger values (as well as
        all non-ASCII ones) will become an attachment, as well as text
        values bigger than 1 kB.

        Extra MIME preamble headers can be specified, too, as a dictionary.

        skip_keys is a set/list specifying keys which are filtered out and not
        written to the destination file.

        priority_fields is a set/list specifying the order in which keys should
        appear in the destination file.

    Provides a general-case interface for Requests sessions to contact HTTP and
    HTTPS urls by implementing the Transport Adapter interface. This class will
    usually be created by the :class:`Session <Session>` class under the
    covers.

    :param pool_connections: The number of urllib3 connection pools to cache.
    :param pool_maxsize: The maximum number of connections to save in the pool.
    :param max_retries: The maximum number of retries each connection
        should attempt. Note, this applies only to failed DNS lookups, socket
        connections and connection timeouts, never to requests where data has
        made it to the server. By default, Requests does not retry failed
        connections. If you need granular control over the conditions under
        which we retry a request, import urllib3's ``Retry`` class and pass
        that instead.
    :param pool_block: Whether the connection pool should block for connections.

    Usage::

      >>> import requests
      >>> s = requests.Session()
      >>> a = requests.adapters.HTTPAdapter(max_retries=3)
      >>> s.mount('http://', a)

Requests HTTP Library
~~~~~~~~~~~~~~~~~~~~~

Requests is an HTTP library, written in Python, for human beings. Basic GET
usage:

   >>> import requests
   >>> r = requests.get('https://www.python.org')
   >>> r.status_code
   200
   >>> 'Python is a programming language' in r.content
   True

... or POST:

   >>> payload = dict(key1='value1', key2='value2')
   >>> r = requests.post('https://httpbin.org/post', data=payload)
   >>> print(r.text)
   {
     ...
     "form": {
       "key2": "value2",
       "key1": "value1"
     },
     ...
   }

The other HTTP methods are supported - see `requests.api`. Full documentation
is at <http://python-requests.org>.

Compatibility code to be able to use `cookielib.CookieJar` with requests.

requests.utils imports from here, so be careful with imports.

    The code in `cookielib.CookieJar` expects this interface in order to correctly
    manage cookie policies, i.e., determine whether a cookie can be set, given the
    domains of the request and the cookie.

    The original request object is read-only. The client is responsible for collecting
    the new headers via `get_new_headers()` and interpreting them appropriately. You
    probably want `get_cookie_header`, defined below.

    ...what? Basically, expose the parsed HTTP headers from the server response
    the way `cookielib` expects to see them.

    uCompatibility class; is a cookielib.CookieJar, but exposes a dict
    interface.

    This is the CookieJar we create by default for requests and sessions that
    don't specify one, since some clients may expect response.cookies and
    session.cookies to support dict operations.

    Requests does not use the dict interface internally; it's just for
    compatibility with external client code. All requests code should work
    out of the box with externally provided instances of ``CookieJar``, e.g.
    ``LWPCookieJar`` and ``FileCookieJar``.

    Unlike a regular CookieJar, this class is pickleable.

        can only be called once for the life of the
        :class:`PreparedRequest <PreparedRequest>` object. Any subsequent calls
        to ``prepare_cookies`` will have no actual effect, unless the "Cookie"

When stream=True is set on the

        large responses.  The chunk size is the number of bytes it should
        read into memory.  This is not necessarily the length of each item
        returned as decoding can take place.

        chunk_size must be of type int or None. A value of None will
        function differently depending on the value of `stream`.
        stream=True will read data as it arrives in whatever size the
        chunks are received. If stream=False, data is returned as
        a single chunk.

        If decode_unicode is True, content will be decoded using the best
        available encoding based on the response.

The ``codes`` object defines a mapping from common names for HTTP statuses
to their numerical codes, accessible either as attributes or as dictionary
items.

>>> requests.codes['temporary_redirect']
307
>>> requests.codes.teapot
418
>>> requests.codes['\o/']
200

Some codes have multiple names, and both upper- and lower-case versions of
the names are allowed. For example, ``codes.ok``, ``codes.OK``, and
``codes.okay`` all correspond to the HTTP status code 200.

~~~~~~~~~~~~~~~~~~~

Data structures that power Requests.
a__doc__u/usr/lib/python3/dist-packages/requests/structures.pya__file__a__spec__aoriginahas_locationa__cached__acompatTaOrderedDictaMappingaMutableMappinglaMutableMappingametaclassa__prepare__a__getitem__u%s.__prepare__() must return a mapping, not %sa__name__u<metaclass>urequests.structuresa__module__uA case-insensitive ``dict``-like object.

    Implements all methods and operations of
    ``MutableMapping`` as well as dict's ``copy``. Also
    provides ``lower_items``.

    All keys are expected to be strings. The structure remembers the
    case of the last key to be set, and ``iter(instance)``,
    ``keys()``, ``items()``, ``iterkeys()``, and ``iteritems()``
    will contain case-sensitive keys. However, querying and contains
    testing is case insensitive::

        cid = CaseInsensitiveDict()
        cid['Accept'] = 'application/json'
        cid['aCCEPT'] == 'application/json'  # True
        list(cid) == ['Accept']  # True

    For example, ``headers['content-encoding']`` will return the
    value of a ``'Content-Encoding'`` response header, regardless
    of how the header name was originally stored.

    If the constructor, ``.update``, or equality comparison
    operations are given keys that have equal ``.lower()``s, the
    behavior is undefined.

    dictionary. Unless it can not be represented as such, return an
    OrderedDict, e.g.,

        OrderedDict([('key', 'val')])
        >>> from_key_val_list('string')
        ValueError: cannot encode objects that are not 2-tuples
        >>> from_key_val_list({'key': 'val'})
        OrderedDict([('key', 'val')])

    :rtype: OrderedDict
    aMappinguTake an object and test to see if it can be represented as a

        [('key', 'val')]
        >>> to_key_val_list({'key': 'val'})

    a_parse_list_header:l��������nn:nlnw"aunquote_header_value:ll��������naresultaappenduParse lists as described by RFC 2068 Section 2.

    In particular, parse comma-separated lists where the elements of
    the list may include quoted-strings.  A quoted-string could
    contain a comma.  A non-quoted string could have quotes in the
    middle.  Quotes are removed automatically after parsing.

    It basically works like :func:`parse_set_header` just that items
    may appear multiple times and case sensitivity is preserved.

    The return value is a standard :class:`list`:

    >>> parse_list_header('token, "quoted value"')
    ['token', 'quoted value']

    To create a header from the :class:`list` again, use the
    :func:`dump_header` function.

    :param value: a string with a list header.
    :return: :class:`list`
    :rtype: list
    w=Tw=luParse lists of key, value pairs as described by RFC 2068 Section 2 and
    convert them into a python dict:

    >>> d = parse_dict_header('foo="is a fish", bar="as well"')
    >>> type(d) is dict
    True
    >>> sorted(d.items())
    [('bar', 'as well'), ('foo', 'is a fish')]

    If there is no value for a key it will be `None`:

    >>> parse_dict_header('key_without_value')
    {'key_without_value': None}

    To create a header from the :class:`dict` again, use the
    :func:`dump_header` function.

    :param value: a string with a dict header.

    ``.write()``-supporting file-like object).

    If *skipkeys* is true then ``dict`` keys that are not basic types
    (``str``, ``unicode``, ``int``, ``long``, ``float``, ``bool``, ``None``)
    will be skipped instead of raising a ``TypeError``.

    If *ensure_ascii* is false, then the some chunks written to ``fp``
    may be ``unicode`` instances, subject to normal Python ``str`` to
    ``unicode`` coercion rules. Unless ``fp.write()`` explicitly
    understands ``unicode`` (as in ``codecs.getwriter()``) this is likely
    to cause an error.

    If *check_circular* is false, then the circular reference check
    for container types will be skipped and a circular reference will
    result in an ``OverflowError`` (or worse).

    If *allow_nan* is false, then it will be a ``ValueError`` to
    serialize out of range ``float`` values (``nan``, ``inf``, ``-inf``)
    in strict compliance of the original JSON specification, instead of using
    the JavaScript equivalents (``NaN``, ``Infinity``, ``-Infinity``). See
    *ignore_nan* for ECMA-262 compliant behavior.

    If *indent* is a string, then JSON array elements and object members
    will be pretty-printed with a newline followed by that string repeated
    for each level of nesting. ``None`` (the default) selects the most compact
    representation without any newlines. For backwards compatibility with
    versions of simplejson earlier than 2.1.0, an integer is also accepted
    and is converted to a string with that many spaces.

    If specified, *separators* should be an
    ``(item_separator, key_separator)`` tuple.  The default is ``(', ', ': ')``
    if *indent* is ``None`` and ``(',', ': ')`` otherwise.  To get the most
    compact JSON representation, you should specify ``(',', ':')`` to eliminate
    whitespace.

    *encoding* is the character encoding for str instances, default is UTF-8.

    *default(obj)* is a function that should return a serializable version
    of obj or raise ``TypeError``. The default simply raises ``TypeError``.

    If *use_decimal* is true (default: ``True``) then decimal.Decimal
    will be natively serialized to JSON with full precision.

    If *namedtuple_as_object* is true (default: ``True``),
    :class:`tuple` subclasses with ``_asdict()`` methods will be encoded
    as JSON objects.

    If *tuple_as_array* is true (default: ``True``),
    :class:`tuple` (and subclasses) will be encoded as JSON arrays.

    If *iterable_as_array* is true (default: ``False``),
    any object not in the above table that implements ``__iter__()``
    will be encoded as a JSON array.

    If *bigint_as_string* is true (default: ``False``), ints 2**53 and higher
    or lower than -2**53 will be encoded as strings. This is to avoid the
    rounding that happens in Javascript otherwise. Note that this is still a
    lossy operation that will not round-trip correctly and should be used
    sparingly.

    If *int_as_string_bitcount* is a positive number (n), then int of size
    greater than or equal to 2**n or lower than or equal to -2**n will be
    encoded as strings.

    If specified, *item_sort_key* is a callable used to sort the items in
    each dictionary. This is useful if you want to sort items other than
    in alphabetical order by key. This option takes precedence over
    *sort_keys*.

    If *sort_keys* is true (default: ``False``), the output of dictionaries
    will be sorted by item.

    If *for_json* is true (default: ``False``), objects with a ``for_json()``
    method will use the return value of that method for encoding as JSON
    instead of the object.

    If *ignore_nan* is true (default: ``False``), then out of range
    :class:`float` values (``nan``, ``inf``, ``-inf``) will be serialized as
    ``null`` in compliance with the ECMA-262 specification. If true, this will
    override *allow_nan*.

    To use a custom ``JSONEncoder`` subclass (e.g. one that overrides the
    ``.default()`` method to serialize additional types), specify it with
    the ``cls`` kwarg. NOTE: You should use *default* or *for_json* instead
    of subclassing whenever possible.

    aencodeuSerialize ``obj`` to a JSON formatted ``str``.

    If ``skipkeys`` is false then ``dict`` keys that are not basic types
    (``str``, ``unicode``, ``int``, ``long``, ``float``, ``bool``, ``None``)
    will be skipped instead of raising a ``TypeError``.

    If ``ensure_ascii`` is false, then the return value will be a
    ``unicode`` instance subject to normal Python ``str`` to ``unicode``
    coercion rules instead of being escaped to an ASCII ``str``.

    If ``check_circular`` is false, then the circular reference check
    for container types will be skipped and a circular reference will
    result in an ``OverflowError`` (or worse).

    If ``allow_nan`` is false, then it will be a ``ValueError`` to
    serialize out of range ``float`` values (``nan``, ``inf``, ``-inf``) in

    If *int_as_string_bitcount* is a positive number (n), then int of size

    aloadsareadaclsaobject_hookaparse_floataparse_intaparse_constantaobject_pairs_hookuDeserialize ``fp`` (a ``.read()``-supporting file-like object containing
    a JSON document) to a Python object.

    *encoding* determines the encoding used to interpret any
    :class:`str` objects decoded by this instance (``'utf-8'`` by
    default).  It has no effect when decoding :class:`unicode` objects.

    Note that currently only encodings that are a superset of ASCII work,
    strings of other encodings should be passed in as :class:`unicode`.

    *object_hook*, if specified, will be called with the result of every
    JSON object decoded and its return value will be used in place of the
    given :class:`dict`.  This can be used to provide custom
    deserializations (e.g. to support JSON-RPC class hinting).

    *object_pairs_hook* is an optional function that will be called with
    the result of any object literal decode with an ordered list of pairs.
    The return value of *object_pairs_hook* will be used instead of the
    :class:`dict`.  This feature can be used to implement custom decoders
    that rely on the order that the key and value pairs are decoded (for
    example, :func:`collections.OrderedDict` will remember the order of
    insertion). If *object_hook* is also defined, the *object_pairs_hook*
    takes priority.

    *parse_float*, if specified, will be called with the string of every
    JSON float to be decoded.  By default, this is equivalent to
    ``float(num_str)``. This can be used to use another datatype or parser
    for JSON floats (e.g. :class:`decimal.Decimal`).

    *parse_int*, if specified, will be called with the string of every
    JSON int to be decoded.  By default, this is equivalent to
    ``int(num_str)``.  This can be used to use another datatype or parser
    for JSON integers (e.g. :class:`float`).

    *parse_constant*, if specified, will be called with one of the
    following strings: ``'-Infinity'``, ``'Infinity'``, ``'NaN'``.  This
    can be used to raise an exception if invalid JSON numbers are
    encountered.

    If *use_decimal* is true (default: ``False``) then it implies
    parse_float=decimal.Decimal for parity with ``dump``.

    To use a custom ``JSONDecoder`` subclass, specify it with the ``cls``
    kwarg. NOTE: You should use *object_hook* or *object_pairs_hook* instead
    of subclassing whenever possible.

    uJSON (JavaScript Object Notation) <http://json.org> is a subset of
JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
interchange format.

:mod:`simplejson` exposes an API familiar to users of the standard library
:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
version of the :mod:`json` library contained in Python 2.6, but maintains
compatibility back to Python 2.5 and (currently) has significant performance
advantages, even without using the optional C extension for speedups.

Encoding basic Python object hierarchies::

    >>> import simplejson as json
    >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
    '["foo", {"bar": ["baz", null, 1.0, 2]}]'
    >>> print(json.dumps("\"foo\bar"))
    "\"foo\bar"
    >>> print(json.dumps(u'\u1234'))
    "\u1234"
    >>> print(json.dumps('\\'))
    "\\"
    >>> print(json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True))
    {"a": 0, "b": 0, "c": 0}
    >>> from simplejson.compat import StringIO
    >>> io = StringIO()
    >>> json.dump(['streaming API'], io)
    >>> io.getvalue()
    '["streaming API"]'

Compact encoding::

    >>> import simplejson as json
    >>> obj = [1,2,3,{'4': 5, '6': 7}]
    >>> json.dumps(obj, separators=(',',':'), sort_keys=True)
    '[1,2,3,{"4":5,"6":7}]'

Pretty printing::

    >>> import simplejson as json
    >>> print(json.dumps({'4': 5, '6': 7}, sort_keys=True, indent='    '))
    {
        "4": 5,
        "6": 7
    }

Decoding JSON::

    >>> import simplejson as json
    >>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
    >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
    True
    >>> json.loads('"\\"foo\\bar"') == u'"foo\x08ar'
    True
    >>> from simplejson.compat import StringIO
    >>> io = StringIO('["streaming API"]')
    >>> json.load(io)[0] == 'streaming API'
    True

Specializing JSON object decoding::

    >>> import simplejson as json
    >>> def as_complex(dct):
    ...     if '__complex__' in dct:
    ...         return complex(dct['real'], dct['imag'])
    ...     return dct
    ...
    >>> json.loads('{"__complex__": true, "real": 1, "imag": 2}',
    ...     object_hook=as_complex)
    (1+2j)
    >>> from decimal import Decimal
    >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
    True

Specializing JSON object encoding::

    >>> import simplejson as json
    >>> def encode_complex(obj):
    ...     if isinstance(obj, complex):
    ...         return [obj.real, obj.imag]
    ...     raise TypeError('Object of type %s is not JSON serializable' %
    ...                     obj.__class__.__name__)
    ...
    >>> json.dumps(2 + 1j, default=encode_complex)
    '[2.0, 1.0]'
    >>> json.JSONEncoder(default=encode_complex).encode(2 + 1j)
    '[2.0, 1.0]'
    >>> ''.join(json.JSONEncoder(default=encode_complex).iterencode(2 + 1j))
    '[2.0, 1.0]'


Using simplejson.tool from the shell to validate and pretty-print::

    $ echo '{"json":"obj"}' | python -m simplejson.tool
    {
        "json": "obj"
    }
    $ echo '{ 1.2:3.4}' | python -m simplejson.tool

        *encoding* determines the encoding used to interpret any
        :class:`str` objects decoded by this instance (``'utf-8'`` by
        default).  It has no effect when decoding :class:`unicode` objects.

        Note that currently only encodings that are a superset of ASCII work,
        strings of other encodings should be passed in as :class:`unicode`.

        *object_hook*, if specified, will be called with the result of every
        JSON object decoded and its return value will be used in place of the
        given :class:`dict`.  This can be used to provide custom
        deserializations (e.g. to support JSON-RPC class hinting).

        *object_pairs_hook* is an optional function that will be called with
        the result of any object literal decode with an ordered list of pairs.
        The return value of *object_pairs_hook* will be used instead of the
        :class:`dict`.  This feature can be used to implement custom decoders
        that rely on the order that the key and value pairs are decoded (for
        example, :func:`collections.OrderedDict` will remember the order of
        insertion). If *object_hook* is also defined, the *object_pairs_hook*
        takes priority.

        *parse_float*, if specified, will be called with the string of every
        JSON float to be decoded.  By default, this is equivalent to
        ``float(num_str)``. This can be used to use another datatype or parser
        for JSON floats (e.g. :class:`decimal.Decimal`).

        *parse_int*, if specified, will be called with the string of every
        JSON int to be decoded.  By default, this is equivalent to
        ``int(num_str)``.  This can be used to use another datatype or parser
        for JSON integers (e.g. :class:`float`).

        *parse_constant*, if specified, will be called with one of the
        following strings: ``'-Infinity'``, ``'Infinity'``, ``'NaN'``.  This
        can be used to raise an exception if invalid JSON numbers are
        encountered.

        *strict* controls the parser's behavior when it encounters an
        invalid control character in a string. The default setting of
        ``True`` means that unescaped control characters are parse errors, if
        ``False`` then control characters will be allowed in strings.

        Optionally, ``idx`` can be used to specify an offset in ``s`` where
        the JSON document begins.

        This can be used to decode a JSON document from a string that may
        have extraneous data at the end.

        If skipkeys is false, then it is a TypeError to attempt
        encoding of keys that are not str, int, long, float or None.  If
        skipkeys is True, such items are simply skipped.

        If ensure_ascii is true, the output is guaranteed to be str
        objects with all incoming unicode characters escaped.  If
        ensure_ascii is false, the output will be unicode object.

        If check_circular is true, then lists, dicts, and custom encoded
        objects will be checked for circular references during encoding to
        prevent an infinite recursion (which would cause an OverflowError).
        Otherwise, no such check takes place.

        If allow_nan is true, then NaN, Infinity, and -Infinity will be
        encoded as such.  This behavior is not JSON specification compliant,
        but is consistent with most JavaScript based encoders and decoders.
        Otherwise, it will be a ValueError to encode such floats.

        If sort_keys is true, then the output of dictionaries will be
        sorted by key; this is useful for regression tests to ensure
        that JSON serializations can be compared on a day-to-day basis.

        If indent is a string, then JSON array elements and object members
        will be pretty-printed with a newline followed by that string repeated
        for each level of nesting. ``None`` (the default) selects the most compact
        representation without any newlines. For backwards compatibility with
        versions of simplejson earlier than 2.1.0, an integer is also accepted
        and is converted to a string with that many spaces.

        If specified, separators should be an (item_separator, key_separator)
        tuple.  The default is (', ', ': ') if *indent* is ``None`` and
        (',', ': ') otherwise.  To get the most compact JSON representation,
        you should specify (',', ':') to eliminate whitespace.

        If specified, default is a function that gets called for objects
        that can't otherwise be serialized.  It should return a JSON encodable
        version of the object or raise a ``TypeError``.

        If encoding is not None, then all input strings will be
        transformed into unicode using that encoding prior to JSON-encoding.
        The default is UTF-8.

        If use_decimal is true (default: ``True``), ``decimal.Decimal`` will
        be supported directly by the encoder. For the inverse, decode JSON
        with ``parse_float=decimal.Decimal``.

        If namedtuple_as_object is true (the default), objects with
        ``_asdict()`` methods will be encoded as JSON objects.

        If tuple_as_array is true (the default), tuple (and subclasses) will
        be encoded as JSON arrays.

        If *iterable_as_array* is true (default: ``False``),
        any object not in the above table that implements ``__iter__()``
        will be encoded as a JSON array.

        If bigint_as_string is true (not the default), ints 2**53 and higher
        or lower than -2**53 will be encoded as strings. This is to avoid the
        rounding that happens in Javascript otherwise.

        If int_as_string_bitcount is a positive number (n), then int of size
        greater than or equal to 2**n or lower than or equal to -2**n will be
        encoded as strings.

        If specified, item_sort_key is a callable used to sort the items in
        each dictionary. This is useful if you want to sort items other than
        in alphabetical order by key.

        If for_json is true (not the default), objects with a ``for_json()``
        method will use the return value of that method for encoding as JSON
        instead of the object.

        If *ignore_nan* is true (default: ``False``), then out of range
        :class:`float` values (``nan``, ``inf``, ``-inf``) will be serialized
        as ``null`` in compliance with the ECMA-262 specification. If true,
        this will override *allow_nan*.

        uObject of type %s is not JSON serializablea__name__uImplement this method in a subclass such that it returns
        a serializable object for ``o``, or calls the base implementation
        (to raise a ``TypeError``).

        For example, to support arbitrary iterators, you could
        implement default like this::

            def default(self, o):
                try:
                    iterable = iter(o)
                except TypeError:
                    pass
                else:
                    return list(iterable)
                return JSONEncoder.default(self, o)

    To extend this to recognize other objects, subclass and implement a
    ``.default()`` method with another method that returns a serializable
    object for ``o`` if possible, otherwise it should call the superclass
    implementation (to raise ``TypeError``).

    To embed JSON content in, say, a script tag on a web page, the

    with the usual entities (e.g. &amp;) because they are not expanded
    within <script> tags.

    This class also escapes the line separator and paragraph separator
    characters U+2028 and U+2029, irrespective of the ensure_ascii setting,

    Scripts may be specified by filename or module name::

        python -m tornado.autoreload -m tornado.test.runtests
        python -m tornado.autoreload tornado/test/runtests.py

    Running a script with this wrapper is similar to calling
    `tornado.autoreload.wait` at the end of the script, but this wrapper
    can catch import-time problems like syntax errors that would otherwise
    prevent the script from reaching its call to `wait`.
    uAutomatically restart the server when a source file is modified.

Most applications should not access this module directly.  Instead,
pass the keyword argument ``autoreload=True`` to the
`tornado.web.Application` constructor (or ``debug=True``, which
enables this setting and several others).  This will enable autoreload
mode as well as checking for changes to templates and static
resources.  Note that restarting is a destructive operation and any
requests in progress will be aborted when the process restarts.  (If
you want to disable autoreload while using other debug-mode features,
pass both ``debug=True`` and ``autoreload=False``).

This module can also be used as a command-line wrapper around scripts
such as unit test runners.  See the `main` method for details.

The command-line wrapper and Application debug modes can be used together.
This combination is encouraged as the wrapper catches syntax errors and
other import-time failures, while debug mode catches changes once
the server has started.

This module will not work correctly when `.HTTPServer`'s multi-process
mode is used.

Reloading loses any Python interpreter command-line arguments (e.g. ``-u``)
because it re-executes Python using ``sys.executable`` and ``sys.argv``.
Additionally, modifying these variables will cause reloading to behave
incorrectly.

    Returns a future.

    The executor to be used is determined by the ``executor``
    attributes of ``self``. To use a different attribute name, pass a
    keyword argument to the decorator::

        @run_on_executor(executor='_thread_pool')
        def foo(self):
            pass

    This decorator should not be confused with the similarly-named
    `.IOLoop.run_in_executor`. In general, using ``run_in_executor``
    when *calling* a blocking method is recommended instead of using
    this decorator when *defining* a method. If compatibility with older
    versions of Tornado is required, consider defining an executor
    and using ``executor.submit()`` at the call site.

    .. versionchanged:: 4.2
       Added keyword arguments to use alternative attributes.

    uUtilities for working with ``Future`` objects.

Tornado previously provided its own ``Future`` class, but now uses
`asyncio.Future`. This module contains utility functions for working
with `asyncio.Future` in a way that is backwards-compatible with
Tornado's old ``Future`` implementation.

While this module is an important part of Tornado's internal
implementation, applications rarely need to interact with it
directly.

    For compatibility with older versions of Python, coroutines may
    also "return" by raising the special exception `Return(value)
    <Return>`.

    Functions with this decorator return a `.Future`.

    .. warning::

       When exceptions occur inside a coroutine, the exception
       information will be stored in the `.Future` object. You must
       examine the result of the `.Future` object, or the exception
       may go unnoticed by your code. This means yielding the function
       if called from another coroutine, using something like
       `.IOLoop.run_sync` for top-level calls, or passing the `.Future`
       to `.IOLoop.add_future`.

    ``children`` may either be a list or a dict whose values are
    yieldable objects. ``multi()`` returns a new yieldable
    object that resolves to a parallel structure containing their
    results. If ``children`` is a list, the result is a list of
    results in the same order; if it is a dict, the result is a dict
    with the same keys.

    That is, ``results = yield multi(list_of_futures)`` is equivalent
    to::

        results = []
        for future in list_of_futures:
            results.append(yield future)

    If any children raise exceptions, ``multi()`` will raise the first
    one. All others will be logged, unless they are of types
    contained in the ``quiet_exceptions`` argument.

    In a ``yield``-based coroutine, it is not normally necessary to
    call this function directly, since the coroutine runner will
    do it automatically when a list or dict is yielded. However,
    it is necessary in ``await``-based coroutines, or to pass
    the ``quiet_exceptions`` argument.

    This function is available under the names ``multi()`` and ``Multi()``
    for historical reasons.

    Cancelling a `.Future` returned by ``multi()`` does not cancel its
    children. `asyncio.gather` is similar to ``multi()``, but it does
    cancel its children.

    .. versionchanged:: 4.2
       If multiple yieldables fail, any exceptions after the first
       (which is raised) will be logged. Added the ``quiet_exceptions``
       argument to suppress this logging for selected exception types.

    .. versionchanged:: 4.3
       Replaced the class ``Multi`` and the function ``multi_future``

    If ``x`` is already a `.Future`, it is simply returned; otherwise
    it is wrapped in a new `.Future`.  This is suitable for use as
    ``result = yield gen.maybe_future(f())`` when you don't know whether
    ``f()`` returns a `.Future` or not.

    .. deprecated:: 4.3
       This function only handles ``Futures``, not other yieldable objects.
       Instead of `maybe_future`, check for the non-future result types
       you expect (often just ``None``), and ``yield`` anything unknown.

    Raises `tornado.util.TimeoutError` if the input future does not
    complete before ``timeout``, which may be specified in any form
    allowed by `.IOLoop.add_timeout` (i.e. a `datetime.timedelta` or
    an absolute time relative to `.IOLoop.time`)

    If the wrapped `.Future` fails after it has timed out, the exception
    will be logged unless it is either of a type contained in
    ``quiet_exceptions`` (which may be an exception type or a sequence of
    types), or an ``asyncio.CancelledError``.

    The wrapped `.Future` is not canceled when the timeout expires,
    permitting it to be reused. `asyncio.wait_for` is similar to this
    function but it does cancel the wrapped `.Future` on timeout.

    analogue to `time.sleep` (which should not be used in coroutines
    because it is blocking)::

        yield gen.sleep(0.5)

    Note that calling this function on its own does nothing; you must
    wait on the `.Future` it returns (usually by yielding it).

    The default implementation accepts lists, dictionaries, and
    Futures. This has the side effect of starting any coroutines that
    did not start themselves, similar to `asyncio.ensure_future`.

    If the `~functools.singledispatch` library is available, this function
    may be extended to support additional types. For example::

        @convert_yielded.register(asyncio.Future)
        def _(asyncio_future):
            return tornado.platform.asyncio.to_tornado_future(asyncio_future)

    .. versionadded:: 4.1

    u``tornado.gen`` implements generator-based coroutines.

.. note::

   The "decorator and generator" approach in this module is a
   precursor to native coroutines (using ``async def`` and ``await``)
   which were introduced in Python 3.5. Applications that do not
   require compatibility with older versions of Python should use
   native coroutines instead. Some parts of this module are still
   useful with native coroutines, notably `multi`, `sleep`,
   `WaitIterator`, and `with_timeout`. Some of these functions have
   counterparts in the `asyncio` module which may be used as well,
   although the two may not necessarily be 100% compatible.

Coroutines provide an easier way to work in an asynchronous
environment than chaining callbacks. Code using coroutines is
technically asynchronous, but it is written as a single generator
instead of a collection of separate functions.

For example, here's a coroutine-based handler:

.. testcode::

    class GenAsyncHandler(RequestHandler):
        @gen.coroutine
        def get(self):
            http_client = AsyncHTTPClient()
            response = yield http_client.fetch("http://example.com")
            do_something_with_response(response)
            self.render("template.html")

.. testoutput::
   :hide:

Asynchronous functions in Tornado return an ``Awaitable`` or `.Future`;
yielding this object returns its result.

You can also yield a list or dict of other yieldable objects, which
will be started at the same time and run in parallel; a list or dict
of results will be returned when they are all finished:

.. testcode::

    @gen.coroutine
    def get(self):
        http_client = AsyncHTTPClient()
        response1, response2 = yield [http_client.fetch(url1),
                                      http_client.fetch(url2)]
        response_dict = yield dict(response3=http_client.fetch(url3),
                                   response4=http_client.fetch(url4))
        response3 = response_dict['response3']
        response4 = response_dict['response4']

.. testoutput::
   :hide:

If ``tornado.platform.twisted`` is imported, it is also possible to
yield Twisted's ``Deferred`` objects. See the `convert_yielded`
function to extend this mechanism.

.. versionchanged:: 3.2

.. versionchanged:: 4.1

    If this exception is raised, its value argument is used as the
    result of the coroutine::

        @gen.coroutine
        def fetch_json(url):
            response = yield AsyncHTTPClient().fetch(url)
            raise gen.Return(json_decode(response.body))

    In Python 3.3, this exception is no longer necessary: the ``return``
    statement can be used directly to return a value (previously
    ``yield`` and ``return`` with a value could not be combined in the
    same function).

    By analogy with the return statement, the value argument is optional,
    but it is never necessary to ``raise gen.Return()``.  The ``return``
    statement can be used with no arguments instead.
    TnuReturn.__init__TOobjectaWaitIteratoruProvides an iterator to yield the results of awaitables as they finish.

    Yielding a set of awaitables like this:

    ``results = yield [awaitable1, awaitable2]``

    pauses the coroutine until both ``awaitable1`` and ``awaitable2``
    return, and then restarts the coroutine with the results of both
    awaitables. If either awaitable raises an exception, the
    expression will raise that exception and all the results will be
    lost.

    If you need to get the result of each awaitable as soon as possible,
    or if you need the result of some awaitables even if others produce
    errors, you can use ``WaitIterator``::

      wait_iterator = gen.WaitIterator(awaitable1, awaitable2)
      while not wait_iterator.done():
          try:
              result = yield wait_iterator.next()
          except Exception as e:
              print("Error {} from {}".format(e, wait_iterator.current_future))
          else:
              print("Result {} received from {} at {}".format(
                  result, wait_iterator.current_future,
                  wait_iterator.current_index))

    Because results are returned as soon as they are available the
    output from the iterator *will not be in the same order as the
    input arguments*. If you need to know which future produced the
    current result, you can use the attributes
    ``WaitIterator.current_future``, or ``WaitIterator.current_index``
    to get the index of the awaitable from the input list. (if keyword
    arguments were used in the construction of the `WaitIterator`,
    ``current_index`` will use the corresponding keyword).

    On Python 3.5, `WaitIterator` implements the async iterator
    protocol, so it can be used with the ``async for`` statement (note
    that in this version the entire iteration is aborted if any value
    raises an exception, while the previous example can continue past
    individual errors)::

      async for result in gen.WaitIterator(future1, future2):
          print("Result {} received from {} at {}".format(
              result, wait_iterator.current_future,
              wait_iterator.current_index))

    .. versionadded:: 4.1

    Handled as a special case in the coroutine runner.

    We lie and tell the type checker that a _NullFuture is a Future so
    we don't have to leak _NullFuture into lots of public APIs. But
    this means that the type checker can't warn us when we're passing
    a _NullFuture into a code path that doesn't understand what to do
    with it.
    u_NullFuture.resultu_NullFuture.doneuA special object which may be yielded to allow the IOLoop to run for
one iteration.

This is not needed in normal use but it can be helpful in long-running
coroutines that are likely to yield Futures that are ready instantly.

Usage: ``yield gen.moment``

In native coroutines, the equivalent of ``yield gen.moment`` is
``await asyncio.sleep(0)``.

        there is not an active delegate (for example, on the server

        The request may be either a string URL or an `HTTPRequest` object.
        If it is a string, we construct an `HTTPRequest` using any additional
        kwargs: ``HTTPRequest(request, **kwargs)``

        If an error occurs during the fetch, we raise an `HTTPError` unless
        the ``raise_error`` keyword argument is set to False.

        This method is **not needed in normal use** due to the way
        that `AsyncHTTPClient` objects are transparently reused.
        ``close()`` is generally only necessary when either the
        `.IOLoop` is also being closed, or the ``force_instance=True``
        argument was used when creating the `AsyncHTTPClient`.

        No other methods may be called on the `AsyncHTTPClient` after
        ``close()``.

        The request may be either a string URL or an `HTTPRequest` object.
        If it is a string, we construct an `HTTPRequest` using any additional
        kwargs: ``HTTPRequest(request, **kwargs)``

        This method returns a `.Future` whose result is an
        `HTTPResponse`. By default, the ``Future`` will raise an
        `HTTPError` if the request returned a non-200 response code
        (other errors may also be raised if the server could not be
        contacted). Instead, if ``raise_error`` is set to False, the
        response will always be returned regardless of the response
        code.

        If a ``callback`` is given, it will be invoked with the `HTTPResponse`.
        In the callback interface, `HTTPError` is not automatically raised.
        Instead, you must check the response's ``error`` attribute or
        call its `~HTTPResponse.rethrow` method.

        .. versionchanged:: 6.0

           The ``callback`` argument was removed. Use the returned
           `.Future` instead.

           The ``raise_error=False`` argument only affects the
           `HTTPError` raised when a non-200 response code is used,
           instead of suppressing all errors.

        ``AsyncHTTPClient()`` actually creates an instance of a subclass.
        This method may be called with either a class object or the
        fully-qualified name of such a class (or ``None`` to use the default,
        ``SimpleAsyncHTTPClient``)

        If additional keyword arguments are given, they will be passed
        to the constructor of each subclass instance created.  The
        keyword argument ``max_clients`` determines the maximum number
        of simultaneous `~AsyncHTTPClient.fetch()` operations that can
        execute in parallel on each `.IOLoop`.  Additional arguments
        may be supported depending on the implementation class in use.

           It is called with one argument, a ``write`` function, and should
           return a `.Future`.  It should call the write function with new
           data as it becomes available.  The write function returns a
           `.Future` which can be used for flow control.
           Only one of ``body`` and ``body_producer`` may
           be specified.  ``body_producer`` is not supported on
           ``curl_httpclient``.  When using ``body_producer`` it is recommended
           to pass a ``Content-Length`` in the headers as otherwise chunked
           encoding will be used, and many servers do not support chunked
           encoding on requests.  New in Tornado 4.0

           the final response.
        :arg collections.abc.Callable header_callback: If set, ``header_callback`` will
           be run with each header line as it is received (including the
           first line, e.g. ``HTTP/1.0 200 OK\r\n``, and a final line
           containing only ``\r\n``.  All lines include the trailing newline
           characters).  ``HTTPResponse.headers`` will be empty in the final
           response.  This is most useful in conjunction with
           ``streaming_callback``, because it's the only way to get access to
           header data while the request is in progress.
        :arg collections.abc.Callable prepare_curl_callback: If set, will be called with

        :arg str ca_certs: filename of CA certificates in PEM format,
           or None to use defaults.  See note below when used with
           ``curl_httpclient``.
        :arg str client_key: Filename for client SSL key, if any.  See
           note below when used with ``curl_httpclient``.
        :arg str client_cert: Filename for client SSL certificate, if any.
           See note below when used with ``curl_httpclient``.
        :arg ssl.SSLContext ssl_options: `ssl.SSLContext` object for use in

        :arg bool expect_100_continue: If true, send the
           ``Expect: 100-continue`` header and wait for a continue response
           before sending the request body.  Only supported with
           ``simple_httpclient``.

        .. note::

            When using ``curl_httpclient`` certain options may be
            inherited by subsequent fetches because ``pycurl`` does
            not allow them to be cleanly reset.  This applies to the
            ``ca_certs``, ``client_key``, ``client_cert``, and
            ``network_interface`` arguments.  If you use these
            options, you should pass them on every request (you don't
            have to always use the same values, but it's not possible
            to mix requests that specify these options with ones that
            use the defaults).

This module defines a common interface shared by two implementations,
``simple_httpclient`` and ``curl_httpclient``.  Applications may either
instantiate their chosen implementation class directly or use the
`AsyncHTTPClient` class from this module, which selects an implementation
that can be overridden with the `AsyncHTTPClient.configure` method.

The default implementation is ``simple_httpclient``, and this is expected
to be suitable for most users' needs.  However, some applications may wish
to switch to ``curl_httpclient`` for reasons such as the following:

* ``curl_httpclient`` has some features not found in ``simple_httpclient``,
  including support for HTTP proxies and the ability to use a specified
  network interface.

* ``curl_httpclient`` is more likely to be compatible with sites that are
  not-quite-compliant with the HTTP spec, or sites that use little-exercised
  features of HTTP.

* ``curl_httpclient`` is faster.

Note that if you are using ``curl_httpclient``, it is highly
recommended that you use a recent version of ``libcurl`` and
``pycurl``.  Currently the minimum supported version of libcurl is
7.22.0, and the minimum version of pycurl is 7.18.2.  It is highly
recommended that your ``libcurl`` installation is built with
asynchronous DNS resolver (threaded or c-ares), otherwise you may
encounter various problems with request timeouts (for more
information, see
http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTCONNECTTIMEOUTMS
and comments in curl_httpclient.py).

To select ``curl_httpclient``, call `AsyncHTTPClient.configure` at startup::

    AsyncHTTPClient.configure("tornado.curl_httpclient.CurlAsyncHTTPClient")

    This interface is provided to make it easier to share code between
    synchronous and asynchronous applications. Applications that are
    running an `.IOLoop` must use `AsyncHTTPClient` instead.

    Typical usage looks like this::

        http_client = httpclient.HTTPClient()
        try:
            response = http_client.fetch("http://www.google.com/")
            print(response.body)
        except httpclient.HTTPError as e:
            # HTTPError is raised for non-200 responses; the response
            # can be found in e.response.
            print("Error: " + str(e))
        except Exception as e:
            # Other errors are possible, such as IOError.
            print("Error: " + str(e))
        http_client.close()

    .. versionchanged:: 5.0

       Due to limitations in `asyncio`, it is no longer possible to
       use the synchronous ``HTTPClient`` while an `.IOLoop` is running.
       Use `AsyncHTTPClient` instead.

    Example usage::

            try:
                response = await http_client.fetch("http://www.google.com")

                print("Error: %s" % e)
            else:
                print(response.body)

    The constructor for this class is magic in several respects: It
    actually creates an instance of an implementation-specific
    subclass, and instances are reused as a kind of pseudo-singleton
    (one per `.IOLoop`). The keyword argument ``force_instance=True``
    can be used to suppress this singleton behavior. Unless
    ``force_instance=True`` is used, no arguments should be passed to
    the `AsyncHTTPClient` constructor. The implementation subclass as
    well as arguments to its constructor can be set with the static
    method `configure()`

    All `AsyncHTTPClient` implementations support a ``defaults``
    keyword argument, which can be used to set default values for
    `HTTPRequest` attributes.  For example::

        AsyncHTTPClient.configure(
            None, defaults=dict(user_agent="MyUserAgent"))
        # or with force_instance:
        client = AsyncHTTPClient(force_instance=True,
            defaults=dict(user_agent="MyUserAgent"))

       is excluded in both implementations. ``request_time`` is now more accurate for
       ``curl_httpclient`` because it uses a monotonic clock when available.

Typical applications have little direct interaction with the `HTTPServer`
class except to start a server at the beginning of the process
(and even that is often done indirectly via `tornado.web.Application.listen`).

.. versionchanged:: 4.0

   The ``HTTPRequest`` class that used to live in this module has been moved
   to `tornado.httputil.HTTPServerRequest`.  The old name remains as an alias.

    A server is defined by a subclass of `.HTTPServerConnectionDelegate`,
    or, for backwards compatibility, a callback that takes an
    `.HTTPServerRequest` as an argument. The delegate is usually a
    `tornado.web.Application`.

    `HTTPServer` supports keep-alive connections by default
    (automatically for HTTP/1.1, or for HTTP/1.0 when the client
    requests ``Connection: keep-alive``).

    If ``xheaders`` is ``True``, we support the
    ``X-Real-Ip``/``X-Forwarded-For`` and
    ``X-Scheme``/``X-Forwarded-Proto`` headers, which override the
    remote IP and URI scheme/protocol for all requests.  These headers
    are useful when running Tornado behind a reverse proxy or load
    balancer.  The ``protocol`` argument can also be set to ``https``
    if Tornado is run behind an SSL-decoding proxy that does not set one of
    the supported ``xheaders``.

    By default, when parsing the ``X-Forwarded-For`` header, Tornado will
    select the last (i.e., the closest) address on the list of hosts as the
    remote host IP address.  To select the next server in the chain, a list of
    trusted downstream hosts may be passed as the ``trusted_downstream``
    argument.  These hosts will be skipped when parsing the ``X-Forwarded-For``
    header.

    To make this server serve SSL traffic, send the ``ssl_options`` keyword
    argument with an `ssl.SSLContext` object. For compatibility with older
    versions of Python ``ssl_options`` may also be a dictionary of keyword
    arguments for the `ssl.wrap_socket` method.::

       ssl_ctx = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
       ssl_ctx.load_cert_chain(os.path.join(data_dir, "mydomain.crt"),
                               os.path.join(data_dir, "mydomain.key"))
       HTTPServer(application, ssl_options=ssl_ctx)

    `HTTPServer` initialization follows one of three patterns (the
    initialization methods are defined on `tornado.tcpserver.TCPServer`):

    1. `~tornado.tcpserver.TCPServer.listen`: single-process::

            async def main():
                server = HTTPServer()
                server.listen(8888)
                await asyncio.Event.wait()

            asyncio.run(main())

       In many cases, `tornado.web.Application.listen` can be used to avoid
       the need to explicitly create the `HTTPServer`.

       While this example does not create multiple processes on its own, when
       the ``reuse_port=True`` argument is passed to ``listen()`` you can run
       the program multiple times to create a multi-process service.

    2. `~tornado.tcpserver.TCPServer.add_sockets`: multi-process::

            sockets = bind_sockets(8888)
            tornado.process.fork_processes(0)
            async def post_fork_main():
                server = HTTPServer()
                server.add_sockets(sockets)
                await asyncio.Event().wait()
            asyncio.run(post_fork_main())

       The ``add_sockets`` interface is more complicated, but it can be used with
       `tornado.process.fork_processes` to run a multi-process service with all
       worker processes forked from a single parent.  ``add_sockets`` can also be
       used in single-process servers if you want to create your listening
       sockets in some way other than `~tornado.netutil.bind_sockets`.

       Note that when using this pattern, nothing that touches the event loop
       can be run before ``fork_processes``.

    3. `~tornado.tcpserver.TCPServer.bind`/`~tornado.tcpserver.TCPServer.start`:
       simple **deprecated** multi-process::

            server = HTTPServer()
            server.bind(8888)
            server.start(0)  # Forks multiple sub-processes
            IOLoop.current().start()

       This pattern is deprecated because it requires interfaces in the
       `asyncio` module that have been deprecated since Python 3.10. Support for
       creating multiple processes in the ``start`` method will be removed in a
       future version of Tornado.

       Added ``decompress_request``, ``chunk_size``, ``max_header_size``,
       ``idle_connection_timeout``, ``body_timeout``, ``max_body_size``

    All attributes are type `str` unless otherwise noted.

    .. attribute:: method

       HTTP request method, e.g. "GET" or "POST"

    .. attribute:: uri

       The requested uri.

    .. attribute:: path

       The path portion of `uri`

    .. attribute:: query

       The query portion of `uri`

    .. attribute:: version

       HTTP version specified in request, e.g. "HTTP/1.1"

    .. attribute:: headers

       `.HTTPHeaders` dictionary-like object for request headers.  Acts like
       a case-insensitive dictionary with additional methods for repeated
       headers.

    .. attribute:: body

       Request body, if present, as a byte string.

    .. attribute:: remote_ip

       Client's IP address as a string.  If ``HTTPServer.xheaders`` is set,
       will pass along the real IP address provided by a load balancer
       in the ``X-Real-Ip`` or ``X-Forwarded-For`` header.

    .. versionchanged:: 3.1
       The list format of ``X-Forwarded-For`` is now supported.

    .. attribute:: protocol

       The protocol used, either "http" or "https".  If ``HTTPServer.xheaders``
       is set, will pass along the protocol used by a load balancer if
       reported via an ``X-Scheme`` header.

    .. attribute:: host

       The requested hostname, usually taken from the ``Host`` header.

    .. attribute:: arguments

       GET/POST arguments are available in the arguments property, which
       maps arguments names to lists of values (to support multiple values
       for individual names). Names are of type `str`, while arguments
       are byte strings.  Note that this is different from
       `.RequestHandler.get_argument`, which returns argument values as
       unicode strings.

    .. attribute:: query_arguments

       Same format as ``arguments``, but contains only arguments extracted
       from the query string.

       .. versionadded:: 3.2

    .. attribute:: files

       File uploads are available in the files property, which maps file
       names to lists of `.HTTPFile`.

    .. attribute:: connection

       An HTTP request is attached to a single HTTP connection, which can
       be accessed through the "connection" attribute. Since connections
       are typically kept open in HTTP/1.1, multiple requests can be handled
       sequentially on a single connection.

        .. versionchanged:: 5.0

           Previously, this method returned a global singleton
           `IOLoop`, in contrast with the per-thread `IOLoop` returned
           by `current()`. In nearly all cases the two were the same
           (when they differed, it was generally used from non-Tornado
           threads to communicate back to the main thread's `IOLoop`).
           This distinction is not present in `asyncio`, so in order
           to facilitate integration with that package `instance()`
           was changed to be an alias to `current()`. Applications
           using the cross-thread communications aspect of
           `instance()` should instead set their own global variable
           to point to the `IOLoop` they want to use.

        .. versionchanged:: 4.1
           Added ``instance`` argument to control the fallback to
           `IOLoop.instance()`.
        .. versionchanged:: 5.0
           On Python 3, control of the current `IOLoop` is delegated
           to `asyncio`, with this and other methods as pass-through accessors.
           The ``instance`` argument now controls whether an `IOLoop`
           is created automatically when there is none, instead of
           whether we fall back to `IOLoop.instance()` (which is now
           an alias for this method). ``instance=False`` is deprecated,
           since even if we do not create an `IOLoop`, this method
           may initialize the asyncio loop.

        .. deprecated:: 6.2
           It is deprecated to call ``IOLoop.current()`` when no `asyncio`
           event loop is running.
        uMakes this the `IOLoop` for the current thread.

        An `IOLoop` automatically becomes current for its thread
        when it is started, but it is sometimes useful to call
        `make_current` explicitly before starting the `IOLoop`,
        so that code run at startup time can find the right
        instance.

        .. versionchanged:: 4.1

        .. deprecated:: 6.2
           The concept of an event loop that is "current" without
           currently running is deprecated in asyncio since Python
           3.10. All related functionality in Tornado is also
           deprecated. Instead, start the event loop with `asyncio.run`
           before interacting with it.

        If ``all_fds`` is true, all file descriptors registered on the
        IOLoop will be closed (not just the ones created by the
        `IOLoop` itself).

        Many applications will only use a single `IOLoop` that runs for the
        entire lifetime of the process.  In that case closing the `IOLoop`
        is not necessary since everything will be cleaned up when the
        process exits.  `IOLoop.close` is provided mainly for scenarios
        such as unit tests, which create and destroy a large number of
        ``IOLoops``.

        An `IOLoop` must be completely stopped before it can be closed.  This
        means that `IOLoop.stop()` must be called *and* `IOLoop.start()` must
        be allowed to return before attempting to call `IOLoop.close()`.
        Therefore the call to `close` will usually appear just after
        the call to `start` rather than near the call to `stop`.

        .. versionchanged:: 3.1
           If the `IOLoop` implementation supports non-integer objects
           for "file descriptors", those objects will have their
           ``close`` method when ``all_fds`` is true.
        uRegisters the given handler to receive the given events for ``fd``.

        The ``fd`` argument may either be an integer file descriptor or
        a file-like object with a ``fileno()`` and ``close()`` method.

        The ``events`` argument is a bitwise or of the constants
        ``IOLoop.READ``, ``IOLoop.WRITE``, and ``IOLoop.ERROR``.

        When an event occurs, ``handler(fd, events)`` will be run.

        will make the loop stop after the current event iteration completes.
        uStop the I/O loop.

        If the event loop is not currently running, the next call to `start()`
        will return immediately.

        Note that even after `stop` has been called, the `IOLoop` is not
        completely stopped until `IOLoop.start` has also returned.
        Some work that was scheduled before the call to `stop` may still
        be run before the `IOLoop` shuts down.

        The function must return either an awaitable object or
        ``None``. If the function returns an awaitable object, the
        `IOLoop` will run until the awaitable is resolved (and
        `run_sync()` will return the awaitable's result). If it raises
        an exception, the `IOLoop` will stop and the exception will be
        re-raised to the caller.

        The keyword-only argument ``timeout`` may be used to set
        a maximum duration for the function.  If the timeout expires,
        a `asyncio.TimeoutError` is raised.

        This method is useful to allow asynchronous calls in a
        ``main()`` function::

        The return value is a floating-point number relative to an
        unspecified time in the past.

        Historically, the IOLoop could be customized to use e.g.
        `time.monotonic` instead of `time.time`, but this is not
        currently supported and so this method is equivalent to
        `time.time`.

        anumbersaRealacall_atadatetimeatimedeltaatotal_secondsuUnsupported deadline %ruRuns the ``callback`` at the time ``deadline`` from the I/O loop.

        Returns an opaque handle that may be passed to
        `remove_timeout` to cancel.

        ``deadline`` may be a number denoting a time (on the same
        scale as `IOLoop.time`, normally `time.time`), or a
        `datetime.timedelta` object for a deadline relative to the
        current time.  Since Tornado 4.0, `call_later` is a more
        convenient alternative for the relative case since it does not
        require a timedelta object.

        Note that it is not safe to call `add_timeout` from other threads.
        Instead, you must use `add_callback` to transfer control to the
        `IOLoop`'s thread, and then call `add_timeout` from there.

        Subclasses of IOLoop must implement either `add_timeout` or
        `call_at`; the default implementations of each will call
        the other.  `call_at` is usually easier to implement, but
        subclasses that wish to maintain compatibility with Tornado
        versions prior to 4.0 must use `add_timeout` instead.

        Returns an opaque handle that may be passed to `remove_timeout`
        to cancel.  Note that unlike the `asyncio` method of the same
        name, the returned object does not have a ``cancel()`` method.

        to cancel.  Note that unlike the `asyncio` method of the same

        uCancels a pending timeout.

        The argument is a handle as returned by `add_timeout`.  It is
        safe to call `remove_timeout` even if the callback has already
        been run.
        uCalls the given callback on the next I/O loop iteration.

        It is safe to call this method from any thread at any time,
        except from a signal handler.  Note that this is the **only**
        method in `IOLoop` that makes this thread-safety guarantee; all
        other interaction with the `IOLoop` must be done from that
        `IOLoop`'s thread.  `add_callback()` may be used to transfer
        control from other threads to the `IOLoop`'s thread.

        To add a callback from a signal handler, see
        `add_callback_from_signal`.

In Tornado 6.0, `.IOLoop` is a wrapper around the `asyncio` event loop, with a
slightly different interface. The `.IOLoop` interface is now provided primarily
for backwards compatibility; new code should generally use the `asyncio` event
loop interface directly. The `IOLoop.current` class method provides the
`IOLoop` instance corresponding to the running `asyncio` event loop.

       :hide:

    Most applications should not attempt to construct an `IOLoop` directly,
    and instead initialize the `asyncio` event loop and use `IOLoop.current()`.
    In some cases, such as in test frameworks when initializing an `IOLoop`
    to be run in a secondary thread, it may be appropriate to construct
    an `IOLoop` with ``IOLoop(make_current=False)``. Constructing an `IOLoop`
    without the ``make_current=False`` argument is deprecated since Tornado 6.2.

    In general, an `IOLoop` cannot survive a fork or be shared across processes
    in any way. When multiple processes are being used, each process should
    create its own `IOLoop`, which also implies that any objects which depend on
    the `IOLoop` (such as `.AsyncHTTPClient`) must also be created in the child
    processes. As a guideline, anything that starts processes (including the
    `tornado.process` and `multiprocessing` modules) should do so as early as
    possible, ideally the first thing the application does after loading its
    configuration, and *before* any calls to `.IOLoop.start` or `asyncio.run`.

    .. versionchanged:: 4.2
       Added the ``make_current`` keyword argument to the `IOLoop`
       constructor.

    .. versionchanged:: 5.0

       Uses the `asyncio` event loop by default. The ``IOLoop.configure`` method
       cannot be used on Python 3 except to redundantly specify the `asyncio`
       event loop.

    .. deprecated:: 6.2
       It is deprecated to create an event loop that is "current" but not
       running. This means it is deprecated to pass
       ``make_current=True`` to the ``IOLoop`` constructor, or to create
       an ``IOLoop`` while no asyncio event loop is running unless
       ``make_current=False`` is used.

    The callback is called every ``callback_time`` milliseconds when
    ``callback_time`` is a float. Note that the timeout is given in
    milliseconds, while most other time-related functions in Tornado use
    seconds. ``callback_time`` may alternatively be given as a
    `datetime.timedelta` object.

    If ``jitter`` is specified, each callback time will be randomly selected
    within a window of ``jitter * callback_time`` milliseconds.
    Jitter can be used to reduce alignment of events with similar periods.
    A jitter of 0.1 means allowing a 10% variation in callback time.
    The window is centered on ``callback_time`` so the total number of calls
    within a given interval should not be significantly affected by adding
    jitter.

    If the callback runs for longer than ``callback_time`` milliseconds,
    subsequent invocations will be skipped to get back on schedule.

    `start` must be called after the `PeriodicCallback` is created.

    .. versionchanged:: 5.0
       The ``io_loop`` argument (deprecated since version 4.1) has been removed.

    .. versionchanged:: 5.1
       The ``jitter`` argument is added.

    .. versionchanged:: 6.2
       If the ``callback`` argument is a coroutine, and a callback runs for
       longer than ``callback_time``, subsequent invocations will be skipped.
       Previously this was only true for regular functions, not coroutines,
       which were "fire-and-forget" for `PeriodicCallback`.

       The ``callback_time`` argument now accepts `datetime.timedelta` objects,
       in addition to the previous numeric milliseconds.

        Implementation notes: Reads and writes have a fast path and a
        slow path.  The fast path reads synchronously from socket
        buffers, while the slow path uses `_add_io_state` to schedule
        an IOLoop callback.

        To detect closed connections, we must have called
        `_add_io_state` at some point, but we want to delay this as
        much as possible so we don't have to set an `IOLoop.ERROR`
        listener that will be overwritten by the next slow-path
        operation. If a sequence of fast-path ops do not end in a
        slow-path op, (e.g. for an @asynchronous long-poll request),
        we must add the error handler.

        May only be called if the socket passed to the constructor was
        not previously connected.  The address parameter is in the
        same format as for `socket.connect <socket.socket.connect>` for
        the type of socket passed to the IOStream constructor,
        e.g. an ``(ip, port)`` tuple.  Hostnames are accepted here,
        but will be resolved synchronously and block the IOLoop.
        If you have a hostname instead of an IP address, the `.TCPClient`
        class is recommended instead of calling this method directly.
        `.TCPClient` will do asynchronous DNS resolution and handle
        both IPv4 and IPv6.

        If ``callback`` is specified, it will be called with no
        arguments when the connection is completed; if not this method
        returns a `.Future` (whose result after a successful
        connection will be the stream itself).

        In SSL mode, the ``server_hostname`` parameter will be used
        for certificate validation (unless disabled in the
        ``ssl_options``) and SNI (if supported; requires Python
        2.7.9+).

        Note that it is safe to call `IOStream.write
        <BaseIOStream.write>` while the connection is pending, in
        which case the data will be written as soon as the connection
        is ready.  Calling `IOStream` read methods before the socket is
        connected works on some platforms but is non-portable.

        This enables protocols that begin in clear-text mode and
        switch to SSL after some initial negotiation (such as the
        ``STARTTLS`` extension to SMTP and IMAP).

        This method cannot be used if there are outstanding reads
        or writes on the stream, or if there is any data in the
        IOStream's buffer (data in the operating system's socket
        buffer is allowed).  This means it must generally be used
        immediately after reading or writing the last clear-text
        data.  It can also be used immediately after connecting,
        before any reads or writes.

        The ``ssl_options`` argument may be either an `ssl.SSLContext`
        object or a dictionary of keyword arguments for the
        `ssl.wrap_socket` function.  The ``server_hostname`` argument
        will be used for certificate validation unless disabled
        in the ``ssl_options``.

        This method returns a `.Future` whose result is the new
        `SSLIOStream`.  After this method has been called,
        any other operation on the original stream is undefined.

        If a close callback is defined on this stream, it will be
        transferred to the new stream.

    We support a non-blocking ``write()`` and a family of ``read_*()``
    methods. When the operation completes, the ``Awaitable`` will resolve
    with the data read (or ``None`` for ``write()``). All outstanding
    ``Awaitables`` will resolve with a `StreamClosedError` when the
    stream is closed; `.BaseIOStream.set_close_callback` can also be used
    to be notified of a closed stream.

    When a stream is closed due to an error, the IOStream's ``error``
    attribute contains the exception object.

    Subclasses must implement `fileno`, `close_fd`, `write_to_fd`,
    `read_from_fd`, and optionally `get_fd_error`.

        By default, data written to TCP streams may be held for a time
        to make the most efficient use of bandwidth (according to
        Nagle's algorithm).  The no-delay flag requests that data be
        written as soon as possible, even if doing so would consume
        additional bandwidth.

        This flag is currently defined only for TCP-based ``IOStreams``.

    The ``socket`` parameter may either be connected or unconnected.
    For server operations the socket is the result of calling
    `socket.accept <socket.socket.accept>`.  For client operations the
    socket is created with `socket.socket`, and may either be
    connected before passing it to the `IOStream` or connected with
    `IOStream.connect`.

    both.

    the locale. Otherwise we move to the next code in the list.

    By default we return ``en_US`` if no translations are found for any of

    Translations are strings with optional Python-style named placeholders
    (e.g., ``My name is %(name)s``) and their associated translations.

    The directory should have translation files of the form ``LOCALE.csv``,
    e.g. ``es_GT.csv``. The CSV files should have two or three columns: string,
    translation, and an optional plural indicator. Plural indicators should
    be one of "plural" or "singular". A given string can have both singular
    and plural forms. For example ``%(name)s liked this`` may have a
    different verb conjugation depending on whether %(name)s is one
    name or a list of names. There should be two rows in the CSV file for
    that string, one with plural indicator "singular", and one "plural".
    For strings with no verbs that would change on translation, simply
    use "unknown" or the empty string (or don't include the column at all).

    The file is read using the `csv` module in the default "excel" dialect.
    In this format there should not be spaces after the commas.

    If no ``encoding`` parameter is given, the encoding will be
    detected automatically (among UTF-8 and UTF-16) if the file
    contains a byte-order marker (BOM), defaulting to UTF-8 if no BOM
    is present.

    Example translation ``es_LA.csv``::

        "I love you","Te amo"

`tornado.locale.get()` returns the closest matching locale, not necessarily the
specific locale you requested. You can support pluralization with
additional arguments to `~Locale.translate()`, e.g.::

    people = [...]
    message = user_locale.translate(
        "%(list)s is online", "%(list)s are online", len(people))
    print(message % {"list": user_locale.list(people)})

The first string is chosen if ``len(people) == 1``, otherwise the second
string is chosen.

Applications should call one of `load_translations` (which uses a simple
CSV format) or `load_gettext_translations` (which uses the ``.mo`` format
supported by `gettext` and related tools).  If neither method is called,
the `Locale.translate` method will simply return the original string.

    a__qualname__u_TimeoutGarbageCollector.__init__u_TimeoutGarbageCollector._garbage_collecta__orig_bases__aConditionuA condition allows one or more coroutines to wait until notified.

    Like a standard `threading.Condition`, but does not need an underlying lock
    that is acquired and released.

    With a `Condition`, coroutines can wait to be notified by other coroutines:

    .. testcode::

        import asyncio
        from tornado import gen
        from tornado.locks import Condition

        condition = Condition()

        async def waiter():
            print("I'll wait right here")
            await condition.wait()
            print("I'm done waiting")

        async def notifier():
            print("About to notify")
            condition.notify()
            print("Done notifying")

        async def runner():
            # Wait for waiter() and notifier() in parallel
            await gen.multi([waiter(), notifier()])

        asyncio.run(runner())

    .. testoutput::

        I'll wait right here
        About to notify
        Done notifying
        I'm done waiting

    `wait` takes an optional ``timeout`` argument, which is either an absolute
    timestamp::

        io_loop = IOLoop.current()

        # Wait up to 1 second for a notification.
        await condition.wait(timeout=io_loop.time() + 1)

    ...or a `datetime.timedelta` for a timeout relative to the current time::

        # Wait up to 1 second.
        await condition.wait(timeout=datetime.timedelta(seconds=1))

    The method returns False if there's no notification before the deadline.

    .. versionchanged:: 5.0
       Previously, waiters could be notified synchronously from within
       `notify`. Now, the notification will always be received on the
       next iteration of the `.IOLoop`.
    areturnastruCondition.__repr__atimeoutafloatatimedeltaaboolawaituCondition.waitaintuCondition.notifyanotify_alluCondition.notify_allaEventuAn event blocks coroutines until its internal flag is set to True.

    Similar to `threading.Event`.

    A coroutine can wait for an event to be set. Once it is set, calls to
    ``yield event.wait()`` will not block unless the event has been cleared:

    .. testcode::

        import asyncio
        from tornado import gen
        from tornado.locks import Event

        event = Event()

        async def waiter():
            print("Waiting for event")
            await event.wait()
            print("Not waiting this time")
            await event.wait()
            print("Done")

        async def setter():
            print("About to set the event")
            event.set()

        async def runner():
            await gen.multi([waiter(), setter()])

        asyncio.run(runner())

    A Semaphore manages a counter representing the number of `.release` calls
    minus the number of `.acquire` calls, plus an initial value. The `.acquire`
    method blocks if necessary until it can return without making the counter
    negative.

    Semaphores limit access to a shared resource. To allow access for two
    workers at a time:

    .. testsetup:: semaphore

       from collections import deque

       from tornado import gen
       from tornado.ioloop import IOLoop
       from tornado.concurrent import Future

       async def simulator(futures):

               futures_q = deque([Future() for _ in range(3)])
               IOLoop.current().add_callback(simulator, list(futures_q))

           return futures_q.popleft()

    .. testcode:: semaphore

        import asyncio
        from tornado import gen
        from tornado.locks import Semaphore

        sem = Semaphore(2)

        async def worker(worker_id):
            await sem.acquire()
            try:
                print("Worker %d is working" % worker_id)
                await use_some_resource()
            finally:
                print("Worker %d is done" % worker_id)
                sem.release()

        async def runner():
            # Join all workers.
            await gen.multi([worker(i) for i in range(3)])

        asyncio.run(runner())

    .. testoutput:: semaphore

        Worker 0 is working
        Worker 1 is working
        Worker 0 is done
        Worker 2 is working
        Worker 1 is done
        Worker 2 is done

    Workers 0 and 1 are allowed to run concurrently, but worker 2 waits until
    the semaphore has been released once, by worker 0.

    The semaphore can be used as an async context manager::

        async def worker(worker_id):
            async with sem:
                print("Worker %d is working" % worker_id)
                await use_some_resource()

            # Now the semaphore has been released.
            print("Worker %d is done" % worker_id)

    For compatibility with older versions of Python, `.acquire` is a
    context manager, so ``worker`` could also be written as::

        @gen.coroutine
        def worker(worker_id):
            with (yield sem.acquire()):
                print("Worker %d is working" % worker_id)
                yield use_some_resource()

            # Now the semaphore has been released.
            print("Worker %d is done" % worker_id)

    .. versionchanged:: 4.3
       Added ``async with`` support in Python 3.5.

    avalueuSemaphore.__init__uSemaphore.__repr__uSemaphore.releaseuSemaphore.acquireuSemaphore.__enter__atypatracebackuSemaphore.__exit__atbuA semaphore that prevents release() being called too many times.

    If `.release` would increment the semaphore's value past the initial
    value, it raises `ValueError`. Semaphores are mostly used to guard
    resources with limited capacity, so a semaphore released too many times
    is a sign of a bug.
    uBoundedSemaphore.__init__uBoundedSemaphore.releaseaLockuA lock for coroutines.

    A Lock begins unlocked, and `acquire` locks it immediately. While it is
    locked, a coroutine that yields `acquire` waits until another coroutine
    calls `release`.

    Releasing an unlocked lock raises `RuntimeError`.

    A Lock can be used as an async context manager with the ``async
    with`` statement:

    >>> from tornado import locks
    >>> lock = locks.Lock()
    >>>
    >>> async def f():
    ...    async with lock:
    ...        # Do something holding the lock.
    ...        pass
    ...
    ...    # Now the lock is released.

    For compatibility with older versions of Python, the `.acquire`
    method asynchronously returns a regular context manager:

    >>> async def f2():
    ...    with (yield lock.acquire()):
    ...        # Do something holding the lock.
    ...        pass
    ...
    ...    # Now the lock is released.

    .. versionchanged:: 4.3

    aenable_pretty_logginguLogging support for Tornado.

Tornado uses three logger streams:

* ``tornado.access``: Per-request logging for Tornado's HTTP servers (and
  potentially other servers in the future)
* ``tornado.application``: Logging of errors from application code (i.e.
  uncaught exceptions from callbacks)
* ``tornado.general``: General-purpose logging, including any errors
  or warnings from Tornado itself.

These streams may be configured independently using the standard library's
`logging` module.  For example, you may wish to send ``tornado.access`` logs
to a separate file for analysis.

    Key features of this formatter are:

    * Color support when logging to a terminal that supports it.
    * Timestamps on every log line.
    * Robust against str/bytes encoding problems.

    This formatter is enabled automatically by
    `tornado.options.parse_command_line` or `tornado.options.parse_config_file`
    (unless ``--logging=none`` is used).

    Color support on Windows versions that do not support ANSI color codes is
    enabled by use of the colorama__ library. Applications that wish to use
    this must first initialize colorama with a call to ``colorama.init``.
    See the colorama documentation for details.

    Returns a list of socket objects (multiple sockets are returned if
    the given address maps to multiple IP addresses, which is most common
    for mixed IPv4 and IPv6 use).

    Address may be either an IP address or hostname.  If it's a hostname,
    the server will listen on all IP addresses associated with the
    name.  Address may be an empty string or None to listen on all
    available interfaces.  Family may be set to either `socket.AF_INET`
    or `socket.AF_INET6` to restrict to IPv4 or IPv6 addresses, otherwise
    both will be used if available.

    The ``backlog`` argument has the same meaning as for
    `socket.listen() <socket.socket.listen>`.

    ``flags`` is a bitmask of AI_* flags to `~socket.getaddrinfo`, like
    ``socket.AI_PASSIVE | socket.AI_NUMERICHOST``.

    ``reuse_port`` option sets ``SO_REUSEPORT`` option for every socket

    When a connection is accepted, ``callback(connection, address)`` will
    be run (``connection`` is a socket object, and ``address`` is the
    address of the other end of the connection).  Note that this signature
    is different from the ``callback(fd, events)`` signature used for
    `.IOLoop` handlers.

    A callable is returned which, when called, will remove the `.IOLoop`
    event handler and stop processing further incoming connections.

    aResolveraDefaultLoopResolveruResolves an address.

        The ``host`` argument is a string which may be a hostname or a
        literal IP address.

        Returns a `.Future` whose result is a list of (family,
        address) pairs, where address is a tuple suitable to pass to
        `socket.connect <socket.socket.connect>` (i.e. a ``(host,
        port)`` pair for IPv4; additional fields may be present for

        ``type`` can be any of `str`, `int`, `float`, `bool`,
        `~datetime.datetime`, or `~datetime.timedelta`. If no ``type``
        is given but a ``default`` is, ``type`` is the type of
        ``default``. Otherwise, ``type`` defaults to `str`.

        If ``multiple`` is True, the option value is a list of ``type``
        instead of an instance of ``type``.

        ``help`` and ``metavar`` are used to construct the
        automatically generated command line help string. The help
        message is formatted like::

           --name=METAVAR      help string

        ``group`` is used to group the defined options in logical
        groups. By default, command line options are grouped by the
        file in which they are defined.

        Command line option names must be unique globally.

        If a ``callback`` is given, it will be run with the new value whenever
        the option is changed.  This can be used to combine command-line
        and file-based options::

            define("config", type=str, help="path to config file",
                   callback=lambda path: parse_config_file(path, final=False))

        With this definition, options in the file specified by ``--config`` will
        override options set earlier on the command line, but can be overridden
        by later flags.

        `sys.argv`).

        Options look like ``--option=value`` and are parsed according
        to their ``type``. For boolean options, ``--option`` is
        equivalent to ``--option=true``

        If the option has ``multiple=True``, comma-separated values
        are accepted. For multi-value integer options, the syntax
        ``x:y`` is also accepted and equivalent to ``range(x, y)``.

        Note that ``args[0]`` is ignored since it is the program name
        in `sys.argv`.

        We return a list of all arguments that are not parsed as options.

        If ``final`` is ``False``, parse callbacks will not be run.
        This is useful for applications that wish to combine configurations
        from multiple sources.

        The config file contains Python code that will be executed (so
        it is **not safe** to use untrusted config files). Anything in
        the global namespace that matches a defined option will be
        used to set that option's value.

        Options may either be the specified type for the option or
        strings (in which case they will be parsed the same way as in
        `.parse_command_line`)

        Example (using the options defined in the top-level docs of
        this module)::

            port = 80
            mysql_host = 'mydb.example.com:3306'
            # Both lists and comma-separated strings are allowed for
            # multiple=True.
            memcache_hosts = ['cache1.example.com:11011',
                              'cache2.example.com:11011']
            memcache_hosts = 'cache1.example.com:11011,cache2.example.com:11011'

        If ``final`` is ``False``, parse callbacks will not be run.
        This is useful for applications that wish to combine configurations
        from multiple sources.

        .. note::

            `tornado.options` is primarily a command-line library.
            Config file support is provided for applications that wish
            to use it, but applications that prefer config files may
            wish to look at other libraries instead.

        .. versionchanged:: 4.1

           the system default encoding.

        .. versionchanged:: 4.4

           files, specifying the absolute path to the config file itself.

    uA command line parsing module that lets modules define their own options.

This module is inspired by Google's `gflags
<https://github.com/google/python-gflags>`_. The primary difference
with libraries such as `argparse` is that a global registry is used so
that options may be defined in any module (it also enables
`tornado.log` by default). The rest of Tornado does not depend on this
module, so feel free to use `argparse` or other configuration
libraries if you prefer them.

Options must be defined with `tornado.options.define` before use,
generally at the top level of a module. The options are then
accessible as attributes of `tornado.options.options`::

    # myapp/db.py
    from tornado.options import define, options

    define("mysql_host", default="127.0.0.1:3306", help="Main user DB")
    define("memcache_hosts", default="127.0.0.1:11011", multiple=True,
           help="Main user memcache servers")

    def connect():
        db = database.Connection(options.mysql_host)
        ...

    # myapp/server.py
    from tornado.options import define, options

    define("port", default=8080, help="port to listen on")

    def start_server():
        app = make_app()
        app.listen(options.port)

The ``main()`` method of your application does not need to be aware of all of
the options used throughout your program; they are all automatically loaded
when the modules are loaded.  However, all modules that define options
must have been imported before the command line is parsed.

Your ``main()`` method can parse the command line or parse a config file with
either `parse_command_line` or `parse_config_file`::

    import myapp.db, myapp.server
    import tornado.options

    if __name__ == '__main__':
        tornado.options.parse_command_line()
        # or
        tornado.options.parse_config_file("/etc/server.conf")

.. note::

   When using multiple ``parse_*`` functions, pass ``final=False`` to all
   but the last one, or side effects may occur twice (in particular,
   this can result in log messages being doubled).

`tornado.options.options` is a singleton instance of `OptionParser`, and
the top-level functions in this module (`define`, `parse_command_line`, etc)
simply call methods on it.  You may create additional `OptionParser`
instances to define isolated sets of options, such as for subcommands.

.. note::

   By default, several options are defined that will configure the
   standard `logging` module when `parse_command_line` or `parse_config_file`
   are called.  If you want Tornado to leave the logging configuration
   alone so you can manage it yourself, either pass ``--logging=none``
   on the command line or do the following to disable it in code::

       from tornado.options import options, parse_command_line
       options.logging = None
       parse_command_line()

.. note::

   `parse_command_line` or `parse_config_file` function should called after
   logging configuration and user-defined command line flags using the
   ``callback`` option definition, or these configurations will not take effect.

.. versionchanged:: 4.3
   Dashes and underscores are fully interchangeable in option names;
   options can be defined, set, and read with any mix of the two.
   Dashes are typical for command-line usage while config files require
   underscores.

    As of ``mock`` version 1.0.1, when an object uses ``__getattr__``
    hooks instead of ``__dict__``, ``patch.__exit__`` tries to delete
    the attribute it set instead of setting a new one (assuming that
    the object does not capture ``__setattr__``, so the patch
    created a new attribute in ``__dict__``).

    _Mockable's getattr and setattr pass through to the underlying
    OptionParser, and delattr undoes the effect of a previous setattr.

.. versionadded:: 3.2

This module integrates Tornado with the ``asyncio`` module introduced
in Python 3.4. This makes it possible to combine the two libraries on
the same event loop.

.. deprecated:: 5.0

   While the code in this module is still used, it is now enabled
   automatically when `asyncio` is available, so applications should
   no longer need to refer to this module directly.

.. note::

   Tornado is designed to use a selector-based event loop. On Windows,
   where a proactor-based event loop has been the default since Python 3.8,
   a selector event loop is emulated by running ``select`` on a separate thread.
   Configuring ``asyncio`` to use a selector event loop may improve performance
   of Tornado (but may reduce performance of other ``asyncio``-based libraries
   in the same process).

    .. deprecated:: 5.0

       Now used automatically when appropriate; it is no longer necessary
       to refer to this class directly.

    .. versionchanged:: 5.0

       Closing an `AsyncIOMainLoop` now closes the underlying asyncio loop.
    uAsyncIOMainLoop.initializeamake_currentuAsyncIOMainLoop.make_currentaAsyncIOLoopu``AsyncIOLoop`` is an `.IOLoop` that runs on an ``asyncio`` event loop.
    This class follows the usual Tornado semantics for creating new
    ``IOLoops``; these loops are not necessarily related to the
    ``asyncio`` default event loop.

    Each ``AsyncIOLoop`` creates a new ``asyncio.EventLoop``; this object
    can be accessed with the ``asyncio_loop`` attribute.

    .. versionchanged:: 6.2

       Support explicit ``asyncio_loop`` argument
       for specifying the asyncio loop to attach to,
       rather than always creating a new one with the default policy.

    .. versionchanged:: 5.0

       When an ``AsyncIOLoop`` becomes the current `.IOLoop`, it also sets
       the current `asyncio` event loop.

    .. deprecated:: 5.0

       Now used automatically when appropriate; it is no longer necessary
       to refer to this class directly.

    The default `asyncio` event loop policy only automatically creates
    event loops in the main threads. Other threads must create event
    loops explicitly or `asyncio.get_event_loop` (and therefore
    `.IOLoop.current`) will fail. Installing this policy allows event
    loops to be created automatically on any thread, matching the
    behavior of Tornado versions prior to 5.0 (or 5.0 on Python 2).

    Usage::

        asyncio.set_event_loop_policy(AnyThreadEventLoopPolicy())

    .. versionadded:: 5.0

    .. deprecated:: 6.2

        ``AnyThreadEventLoopPolicy`` affects the implicit creation
        of an event loop, which is deprecated in Python 3.10 and
        will be removed in a future version of Python. At that time
        ``AnyThreadEventLoopPolicy`` will no longer be useful.
        If you are relying on it, use `asyncio.new_event_loop`
        or `asyncio.run` explicitly in any non-main threads that
        need event loops.
    uAnyThreadEventLoopPolicy.__init__uAnyThreadEventLoopPolicy.get_event_loopuWrap an event loop to add implementations of the ``add_reader`` method family.

    Instances of this class start a second thread to run a selector.
    This thread is completely hidden from the user; all callbacks are
    run on the wrapped event loop's thread.

    This class is used automatically by Tornado; applications should not need
    to refer to it directly.

    It is safe to wrap any event loop with this class, although it only makes sense
    for event loops that do not implement the ``add_reader`` family of methods
    themselves (i.e. ``WindowsProactorEventLoop``)

    Closing the ``AddThreadSelectorEventLoop`` also closes the wrapped event loop.

    If ``num_processes`` is None or <= 0, we detect the number of cores
    available on this machine and fork that number of child
    processes. If ``num_processes`` is given and > 0, we fork that
    specific number of sub-processes.

    Since we use processes and not threads, there is no shared memory
    between any server code.

    Note that multiple processes are not compatible with the autoreload
    module (or the ``autoreload=True`` option to `tornado.web.Application`
    which defaults to True when ``debug=True``).
    When using multiple processes, no IOLoops can be created or
    referenced until after the call to ``fork_processes``.

    In each child process, ``fork_processes`` returns its *task id*, a
    number between 0 and ``num_processes``.  Processes that exit
    abnormally (due to a signal or non-zero exit status) are restarted
    with the same id (up to ``max_restarts`` times).  In the parent
    process, ``fork_processes`` calls ``sys.exit(0)`` after all child
    processes have exited normally.

    max_restarts defaults to 100.

        The callback takes one argument, the return code of the process.

        This method uses a ``SIGCHLD`` handler, which is a global setting
        and may conflict if you have other libraries trying to handle the
        same signal.  If you are using more than one ``IOLoop`` it may
        be necessary to call `Subprocess.initialize` first to designate
        one ``IOLoop`` to run the signal handlers.

        In many cases a close callback on the stdout or stderr streams
        can be used as an alternative to an exit callback if the
        signal handler is causing a problem.

        This is a coroutine-friendly alternative to `set_exit_callback`
        (and a replacement for the blocking `subprocess.Popen.wait`).

        By default, raises `subprocess.CalledProcessError` if the process
        has a non-zero exit status. Use ``wait_for_exit(raise_error=False)``
        to suppress this behavior and return the exit status without raising.

        .. note::

           The ``timeout`` argument of this method differs from that
           of the standard library's `queue.Queue.get`. That method
           interprets numeric values as relative timeouts; this one
           interprets them as absolute deadlines and requires
           ``timedelta`` objects for relative timeouts (consistent

        Used by queue consumers. For each `.get` used to fetch a task, a

        on the task is complete.

        If a `.join` is blocking, it resumes when all items have been
        processed; that is, when every `.put` is matched by a `.task_done`.

        In the examples above, ``Target`` can be a nested `Router` instance, an instance of

    uFlexible routing implementation.

Tornado routes HTTP requests to appropriate handlers using `Router`
class implementations. The `tornado.web.Application` class is a
`Router` implementation and may be used directly, or the classes in
this module may be used for additional flexibility. The `RuleRouter`
class can match on more criteria than `.Application`, or the `Router`
interface can be subclassed for maximum customization.

`Router` interface extends `~.httputil.HTTPServerConnectionDelegate`
to provide additional routing capabilities. This also means that any
`Router` implementation can be used directly as a ``request_callback``
for `~.httpserver.HTTPServer` constructor.

`Router` subclass must implement a ``find_handler`` method to provide
a suitable `~.httputil.HTTPMessageDelegate` instance to handle the
request:

.. code-block:: python

    class CustomRouter(Router):
        def find_handler(self, request, **kwargs):
            # some routing logic providing a suitable HTTPMessageDelegate instance
            return MessageDelegate(request.connection)

    class MessageDelegate(HTTPMessageDelegate):
        def __init__(self, connection):
            self.connection = connection

        def finish(self):
            self.connection.write_headers(
                ResponseStartLine("HTTP/1.1", 200, "OK"),
                HTTPHeaders({"Content-Length": "2"}),
                b"OK")
            self.connection.finish()

    router = CustomRouter()
    server = HTTPServer(router)

The main responsibility of `Router` implementation is to provide a
mapping from a request to `~.httputil.HTTPMessageDelegate` instance
that will handle this request. In the example above we can see that
routing is possible even without instantiating an `~.web.Application`.

For routing to `~.web.RequestHandler` implementations we need an
`~.web.Application` instance. `~.web.Application.get_handler_delegate`
provides a convenient way to create `~.httputil.HTTPMessageDelegate`
for a given request and `~.web.RequestHandler`.

Here is a simple example of how we can we route to
`~.web.RequestHandler` subclasses by HTTP method:

.. code-block:: python

    resources = {}

    class GetResource(RequestHandler):
        def get(self, path):
            if path not in resources:
                raise HTTPError(404)

            self.finish(resources[path])

    class PostResource(RequestHandler):
        def post(self, path):
            resources[path] = self.request.body

    class HTTPMethodRouter(Router):
        def __init__(self, app):
            self.app = app

        def find_handler(self, request, **kwargs):
            handler = GetResource if request.method == "GET" else PostResource
            return self.app.get_handler_delegate(request, handler, path_args=[request.path])

    router = HTTPMethodRouter(Application())
    server = HTTPServer(router)

`ReversibleRouter` interface adds the ability to distinguish between
the routes and reverse them to the original urls using route's name
and additional arguments. `~.web.Application` is itself an
implementation of `ReversibleRouter` class.

`RuleRouter` and `ReversibleRuleRouter` are implementations of
`Router` and `ReversibleRouter` interfaces and can be used for
creating rule-based routing configurations.

Rules are instances of `Rule` class. They contain a `Matcher`, which
provides the logic for determining whether the rule is a match for a
particular request and a target, which can be one of the following.

1) An instance of `~.httputil.HTTPServerConnectionDelegate`:

.. code-block:: python

    router = RuleRouter([
        Rule(PathMatches("/handler"), ConnectionDelegate()),
        # ... more rules
    ])

    class ConnectionDelegate(HTTPServerConnectionDelegate):
        def start_request(self, server_conn, request_conn):
            return MessageDelegate(request_conn)

2) A callable accepting a single argument of `~.httputil.HTTPServerRequest` type:

.. code-block:: python

    router = RuleRouter([
        Rule(PathMatches("/callable"), request_callable)
    ])

    def request_callable(request):
        request.write(b"HTTP/1.1 200 OK\r\nContent-Length: 2\r\n\r\nOK")
        request.finish()

3) Another `Router` instance:

.. code-block:: python

    router = RuleRouter([
        Rule(PathMatches("/router.*"), CustomRouter())
    ])

Of course a nested `RuleRouter` or a `~.web.Application` is allowed:

.. code-block:: python

    router = RuleRouter([
        Rule(HostMatches("example.com"), RuleRouter([
            Rule(PathMatches("/app1/.*"), Application([(r"/app1/handler", Handler)])),
        ]))
    ])

    server = HTTPServer(router)

In the example below `RuleRouter` is used to route between applications:

.. code-block:: python

    app1 = Application([
        (r"/app1/handler", Handler1),
        # other handlers ...
    ])

    app2 = Application([
        (r"/app2/handler", Handler2),
        # other handlers ...
    ])

    router = RuleRouter([
        Rule(PathMatches("/app1.*"), app1),
        Rule(PathMatches("/app2.*"), app2)
    ])

    server = HTTPServer(router)

For more information on application-level routing see docs for `~.web.Application`.

    This class implements an HTTP 1.1 client on top of Tornado's IOStreams.
    Some features found in the curl-based AsyncHTTPClient are not yet
    supported.  In particular, proxies are not supported, connections
    are not reused, and callers cannot select the network interface to be
    used.

    This implementation supports the following arguments, which can be passed
    to ``configure()`` to control the global singleton, or to the constructor
    when ``force_instance=True``.

    ``max_clients`` is the number of concurrent requests that can be
    in progress; when this limit is reached additional requests will be
    queued. Note that time spent waiting in this queue still counts
    against the ``request_timeout``.

    ``defaults`` is a dict of parameters that will be used as defaults on all
    `.HTTPRequest` objects submitted to this client.

    ``hostname_mapping`` is a dictionary mapping hostnames to IP addresses.
    It can be used to make local DNS changes when modifying system-wide
    settings like ``/etc/hosts`` is not possible or desirable (e.g. in
    unittests). ``resolver`` is similar, but using the `.Resolver` interface
    instead of a simple mapping.

    ``max_buffer_size`` (default 100MB) is the number of bytes
    that can be read into memory at once. ``max_body_size``
    (defaults to ``max_buffer_size``) is the largest response body
    that the client will accept.  Without a
    ``streaming_callback``, the smaller of these two limits
    applies; with a ``streaming_callback`` only ``max_body_size``
    does.

    .. versionchanged:: 4.2
        Added the ``max_body_size`` argument.

        In case the user needs to resolve and
        use a specific interface, it has to be handled outside
        of Tornado as this depends very much on the platform.

        Raises `TimeoutError` if the input future does not complete before

        relative to `.IOLoop.time`)

        Similarly, when the user requires a certain source port, it can

    "Happy Eyeballs" is documented in RFC6555 as the recommended practice
    for when both IPv4 and IPv6 addresses are available.

    In this implementation, we partition the addresses by family, and
    make the first connection attempt to whichever address was
    returned first by ``getaddrinfo``.  If that connection fails or
    times out, we begin a connection in parallel to the first address
    of the other family.  If there are additional failures we retry
    with other addresses, keeping one connection attempt per family
    in flight at a time.

        This method may be called more than once to listen on multiple ports.
        `listen` takes effect immediately; it is not necessary to call
        `TCPServer.start` afterwards.  It is, however, necessary to start the
        event loop if it is not already running.

        All arguments have the same meaning as in
        `tornado.netutil.bind_sockets`.

        .. versionchanged:: 6.2

        The ``sockets`` parameter is a list of socket objects such as
        those returned by `~tornado.netutil.bind_sockets`.
        `add_sockets` is typically used in combination with that
        method and `tornado.process.fork_processes` to provide greater
        control over the initialization of a multi-process server.
        uSingular version of `add_sockets`.  Takes a single socket object.aextenduBinds this server to the given port on the given address.

        To start the server, call `start`. If you want to run this server in a
        single process, you can call `listen` as a shortcut to the sequence of
        `bind` and `start` calls.

        Address may be either an IP address or hostname.  If it's a hostname,
        the server will listen on all IP addresses associated with the name.
        Address may be an empty string or None to listen on all available
        interfaces.  Family may be set to either `socket.AF_INET` or
        `socket.AF_INET6` to restrict to IPv4 or IPv6 addresses, otherwise both
        will be used if available.

        The ``backlog`` argument has the same meaning as for `socket.listen
        <socket.socket.listen>`. The ``reuse_port`` argument has the same
        meaning as for `.bind_sockets`.

        This method may be called multiple times prior to `start` to listen on
        multiple ports or interfaces.

        .. versionchanged:: 4.4
           Added the ``reuse_port`` argument.

        .. deprecated:: 6.2
           Use either ``listen()`` or ``add_sockets()`` instead of ``bind()``
           and ``start()``. The ``bind()/start()`` pattern depends on
           interfaces that have been deprecated in Python 3.10 and will be
           removed in future versions of Python.
        laprocessafork_processesuStarts this server in the `.IOLoop`.

        By default, we run the server in this process and do not fork any
        additional child process.

        If num_processes is ``None`` or <= 0, we detect the number of cores
        available on this machine and fork that number of child
        processes. If num_processes is given and > 1, we fork that
        specific number of sub-processes.

        Since we use processes and not threads, there is no shared memory
        between any server code.

        Note that multiple processes are not compatible with the autoreload
        module (or the ``autoreload=True`` option to `tornado.web.Application`
        which defaults to True when ``debug=True``).
        When using multiple processes, no IOLoops can be created or
        referenced until after the call to ``TCPServer.start(n)``.

        Values of ``num_processes`` other than 1 are not supported on Windows.

        The ``max_restarts`` argument is passed to `.fork_processes`.

        .. versionchanged:: 6.0

           Added ``max_restarts`` argument.

        .. deprecated:: 6.2

        If this `TCPServer` is configured for SSL, ``handle_stream``
        may be called before the SSL handshake has completed. Use

        certificate or use NPN/ALPN.

    To use `TCPServer`, define a subclass which overrides the `handle_stream`
    method. For example, a simple echo server could be defined like this::

      from tornado.tcpserver import TCPServer
      from tornado.iostream import StreamClosedError

      class EchoServer(TCPServer):
          async def handle_stream(self, stream, address):
              while True:
                  try:
                      data = await stream.read_until(b"\n") await
                      stream.write(data)
                  except StreamClosedError:
                      break

    To make this server serve SSL traffic, send the ``ssl_options`` keyword
    argument with an `ssl.SSLContext` object. For compatibility with older
    versions of Python ``ssl_options`` may also be a dictionary of keyword
    arguments for the `ssl.wrap_socket` method.::

       ssl_ctx = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
       ssl_ctx.load_cert_chain(os.path.join(data_dir, "mydomain.crt"),
                               os.path.join(data_dir, "mydomain.key"))
       TCPServer(ssl_options=ssl_ctx)

    `TCPServer` initialization follows one of three patterns:

    1. `listen`: single-process::

            async def main():
                server = TCPServer()
                server.listen(8888)
                await asyncio.Event.wait()

            asyncio.run(main())

       While this example does not create multiple processes on its own, when
       the ``reuse_port=True`` argument is passed to ``listen()`` you can run
       the program multiple times to create a multi-process service.

    2. `add_sockets`: multi-process::

            sockets = bind_sockets(8888)
            tornado.process.fork_processes(0)
            async def post_fork_main():
                server = TCPServer()
                server.add_sockets(sockets)
                await asyncio.Event().wait()
            asyncio.run(post_fork_main())

       The `add_sockets` interface is more complicated, but it can be used with
       `tornado.process.fork_processes` to run a multi-process service with all
       worker processes forked from a single parent.  `add_sockets` can also be
       used in single-process servers if you want to create your listening
       sockets in some way other than `~tornado.netutil.bind_sockets`.

       Note that when using this pattern, nothing that touches the event loop
       can be run before ``fork_processes``.

    3. `bind`/`start`: simple **deprecated** multi-process::

            server = TCPServer()
            server.bind(8888)
            server.start(0)  # Forks multiple sub-processes
            IOLoop.current().start()

       This pattern is deprecated because it requires interfaces in the
       `asyncio` module that have been deprecated since Python 3.10. Support for
       creating multiple processes in the ``start`` method will be removed in a
       future version of Tornado.

Basic usage looks like::

    t = template.Template("<html>{{ myvalue }}</html>")
    print(t.generate(myvalue="XXX"))

`Loader` is a class that loads templates from a root directory and caches
the compiled templates::

    loader = template.Loader("/home/btaylor")
    print(loader.load("test.html").generate(myvalue="XXX"))

We compile all templates to raw Python. Error-reporting is currently... uh,
interesting. Syntax for the templates::

    ### base.html
    <html>
      <head>
        <title>{% block title %}Default title{% end %}</title>
      </head>
      <body>
        <ul>
          {% for student in students %}
            {% block student %}
              <li>{{ escape(student.name) }}</li>
            {% end %}
          {% end %}
        </ul>
      </body>
    </html>

    ### bold.html
    {% extends "base.html" %}

    {% block title %}A bolder title{% end %}

    {% block student %}
      <li><span style="bold">{{ escape(student.name) }}</span></li>
    {% end %}

Unlike most other template systems, we do not put any restrictions on the
expressions you can include in your statements. ``if`` and ``for`` blocks get
translated exactly into Python, so you can do complex expressions like::

   {% for student in [p for p in people if p.student and p.age > 23] %}
     <li>{{ escape(student.name) }}</li>
   {% end %}

Translating directly to Python means you can apply functions to expressions
easily, like the ``escape()`` function in the examples above. You can pass
functions in to your template just like any other variable
(In a `.RequestHandler`, override `.RequestHandler.get_template_namespace`)::

   ### Python code
   def add(x, y):
      return x + y
   template.execute(add=add)

   ### The template
   {{ add(1, 2) }}

We provide the functions `escape() <.xhtml_escape>`, `.url_escape()`,
`.json_encode()`, and `.squeeze()` to all templates by default.

Typical applications do not create `Template` or `Loader` instances by
hand, but instead use the `~.RequestHandler.render` and
`~.RequestHandler.render_string` methods of
`tornado.web.RequestHandler`, which load templates automatically based
on the ``template_path`` `.Application` setting.

Variable names beginning with ``_tt_`` are reserved by the template
system and should not be used by application code.

Syntax Reference
----------------

Template expressions are surrounded by double curly braces: ``{{ ... }}``.
The contents may be any python expression, which will be escaped according
to the current autoescape setting and inserted into the output.  Other
template directives use ``{% %}``.

To comment out a section so that it is omitted from the output, surround it
with ``{# ... #}``.


To include a literal ``{{``, ``{%``, or ``{#`` in the output, escape them as
``{{!``, ``{%!``, and ``{#!``, respectively.


``{% apply *function* %}...{% end %}``
    Applies a function to the output of all template code between ``apply``
    and ``end``::

        {% apply linkify %}{{name}} said: {{message}}{% end %}

    Note that as an implementation detail apply blocks are implemented
    as nested functions and thus may interact strangely with variables
    set via ``{% set %}``, or the use of ``{% break %}`` or ``{% continue %}``
    within loops.

``{% autoescape *function* %}``
    Sets the autoescape mode for the current file.  This does not affect
    other files, even those referenced by ``{% include %}``.  Note that
    autoescaping can also be configured globally, at the `.Application`
    or `Loader`.::

        {% autoescape xhtml_escape %}
        {% autoescape None %}

``{% block *name* %}...{% end %}``
    Indicates a named, replaceable block for use with ``{% extends %}``.
    Blocks in the parent template will be replaced with the contents of
    the same-named block in a child template.::

        <!-- base.html -->
        <title>{% block title %}Default title{% end %}</title>

        <!-- mypage.html -->
        {% extends "base.html" %}
        {% block title %}My page title{% end %}

``{% comment ... %}``
    A comment which will be removed from the template output.  Note that
    there is no ``{% end %}`` tag; the comment goes from the word ``comment``
    to the closing ``%}`` tag.

``{% extends *filename* %}``
    Inherit from another template.  Templates that use ``extends`` should
    contain one or more ``block`` tags to replace content from the parent
    template.  Anything in the child template not contained in a ``block``
    tag will be ignored.  For an example, see the ``{% block %}`` tag.

``{% for *var* in *expr* %}...{% end %}``
    Same as the python ``for`` statement.  ``{% break %}`` and
    ``{% continue %}`` may be used inside the loop.

``{% from *x* import *y* %}``
    Same as the python ``import`` statement.

``{% if *condition* %}...{% elif *condition* %}...{% else %}...{% end %}``
    Conditional statement - outputs the first section whose condition is
    true.  (The ``elif`` and ``else`` sections are optional)

``{% import *module* %}``
    Same as the python ``import`` statement.

``{% include *filename* %}``
    Includes another template file.  The included file can see all the local
    variables as if it were copied directly to the point of the ``include``
    directive (the ``{% autoescape %}`` directive is an exception).
    Alternately, ``{% module Template(filename, **kwargs) %}`` may be used
    to include another template with an isolated namespace.

``{% module *expr* %}``
    Renders a `~tornado.web.UIModule`.  The output of the ``UIModule`` is
    not escaped::

        {% module Template("foo.html", arg=42) %}

    ``UIModules`` are a feature of the `tornado.web.RequestHandler`
    class (and specifically its ``render`` method) and will not work
    when the template system is used on its own in other contexts.

``{% raw *expr* %}``
    Outputs the result of the given expression without autoescaping.

``{% set *x* = *y* %}``
    Sets a local variable.

``{% try %}...{% except %}...{% else %}...{% finally %}...{% end %}``
    Same as the python ``try`` statement.

``{% while *condition* %}... {% end %}``
    Same as the python ``while`` statement.  ``{% break %}`` and
    ``{% continue %}`` may be used inside the loop.

``{% whitespace *mode* %}``
    Sets the whitespace mode for the remainder of the current file
    (or until the next ``{% whitespace %}`` directive). See
    `filter_whitespace` for available options. New in Tornado 4.3.

    uMiscellaneous utility functions and classes.

This module is used internally by Tornado.  It is not necessarily expected
that the functions and classes defined here will be useful to other
applications, but they are documented here in case they are.

The one public-facing part of this module is the `Configurable` class
and its `~Configurable.configure` method, which becomes a part of the
interface of its subclasses, including `.AsyncHTTPClient`, `.IOLoop`,
and `.Resolver`.

    A configurable interface is an (abstract) class whose constructor
    acts as a factory function for one of its implementation subclasses.
    The implementation subclass as well as optional keyword arguments to
    its initializer can be set globally at runtime with `configure`.

    By using the constructor as the factory method, the interface
    looks like a normal class, `isinstance` works as usual, etc.  This
    pattern is most useful when the choice of implementation is likely
    to be a global decision (e.g. when `~select.epoll` is available,
    always use it instead of `~select.select`), or when a
    previously-monolithic class has been split into specialized
    subclasses.

    Configurable subclasses must define the class methods
    `configurable_base` and `configurable_default`, and use the instance
    method `initialize` instead of ``__init__``.

    .. versionchanged:: 5.0

       It is now possible for configuration to be specified at
       multiple levels of a class hierarchy.

        Override this to clean up resources associated with

        the connection was closed during asynchronous processing; if you
        need to do cleanup after every request override `on_finish`
        instead.

        Proxies may keep a connection open for a time (perhaps
        indefinitely) after the client has gone away, so this method
        may not be called promptly after the end user closes their
        connection.

        Unlike `set_header`, `add_header` may be called multiple times
        to return multiple values for the same header.

        The argument has been percent-decoded and is now a byte string.
        By default, this method decodes the argument as utf-8 and returns
        a unicode string, but this may be overridden in subclasses.

        This method is used as a filter for both `get_argument()` and for
        values extracted from the url and passed to `get()`/`post()`/etc.

        This method only returns cookies that were present in the request.
        It does not see the outgoing cookies set by `set_cookie` in this
        handler.

        Newly-set cookies are not immediately visible via `get_cookie`;
        they are not present until the next request.

        expires may be a numeric timestamp as returned by `time.time`,
        a time tuple as returned by `time.gmtime`, or a
        `datetime.datetime` object.

        Additional keyword arguments are set on the cookies.Morsel
        directly.
        See https://docs.python.org/3/library/http.cookies.html#http.cookies.Morsel
        for available attributes.
        Tlmaset_cookieuTavalueapathaexpiresadomainuDeletes the cookie with the given name.

        Due to limitations of the cookie protocol, you must pass the same
        path and domain to clear a cookie as were used when that cookie
        was set (but there is no way to find out on the server side
        which values were used for a given cookie).

        Similar to `set_cookie`, the effect of this method will not be
        seen until the following request.
        aclear_cookieTapathadomainuDeletes all the cookies the user sent with this request.

        See `clear_cookie` for more information on the path and domain
        parameters.

        Similar to `set_cookie`, the effect of this method will not be
        seen until the following request.

        .. versionchanged:: 3.2

           Added the ``path`` and ``domain`` parameters.
        acreate_signed_valueTaversionaexpires_daysuSigns and timestamps a cookie so it cannot be forged.

        You must specify the ``cookie_secret`` setting in your Application
        to use this method. It should be a long, random sequence of bytes
        to be used as the HMAC secret for the signature.

        To read a cookie set with this method, use `get_secure_cookie()`.

        Note that the ``expires_days`` parameter sets the lifetime of the
        cookie in the browser, but is independent of the ``max_age_days``
        parameter to `get_secure_cookie`.
        A value of None limits the lifetime to the current browser session.

        Secure cookies may contain arbitrary byte values, not just unicode
        strings (unlike regular cookies)

        Similar to `set_cookie`, the effect of this method will not be
        seen until the following request.

        .. versionchanged:: 3.2.1

        Normally used via set_secure_cookie, but provided as a separate

        as a cookie use the optional value argument to get_secure_cookie.

        The decoded cookie value is returned as a byte string (unlike
        `get_cookie`).

        Similar to `get_cookie`, this method only returns cookies that
        were present in the request. It does not see outgoing cookies set by
        `set_secure_cookie` in this handler.

        .. versionchanged:: 3.2.1

           Added the ``min_version`` argument.  Introduced cookie version 2;
           both versions 1 and 2 are accepted by default.

        The version is returned as int.

        If the ``status`` argument is specified, that value is used as the
        HTTP status code; otherwise either 301 (permanent) or 302
        (temporary) is chosen based on the ``permanent`` argument.
        The default is 302 (temporary).
        uCannot write() after finish()uwrite() only accepts bytes, unicode, and dict objectsu.

        To write the output to the network, use the `flush()` method below.

        If the given chunk is a dictionary, we write it as JSON and set
        the Content-Type of the response to be ``application/json``.
        (if you want to send JSON as a different ``Content-Type``, call
        ``set_header`` *after* calling ``write()``).

        Note that lists are not converted to JSON because of a potential
        cross-site security vulnerability.  All JSON output should be
        wrapped in a dictionary.  More details at

        a_current_useraget_current_useruThe authenticated user for this request.

        This is set in one of two ways:

        * A subclass may override `get_current_user()`, which will be called
          automatically the first time ``self.current_user`` is accessed.
          `get_current_user()` will only be called once per request,
          and is cached for future access::

              def get_current_user(self):
                  user_cookie = self.get_secure_cookie("user")
                  if user_cookie:
                      return json.loads(user_cookie)
                  return None

        * It may be set as a normal variable, typically from an overridden
          `prepare()`::

              @gen.coroutine
              def prepare(self):
                  user_id_cookie = self.get_secure_cookie("user_id")
                  if user_id_cookie:
                      self.current_user = yield load_user(user_id_cookie)

        Note that `prepare()` may be a coroutine while `get_current_user()`
        may not, so the latter form is necessary if loading the user requires
        asynchronous operations.

        The user object may be any type of the application's choosing.
        Talogin_urlu@tornado.web.authenticatedalogin_urluOverride to customize the login URL based on the request.

        To prevent cross-site request forgery, we set an '_xsrf' cookie
        and include the same '_xsrf' value as an argument with all POST
        requests. If the two do not match, we reject the form submission
        as a potential forgery.

        See http://en.wikipedia.org/wiki/Cross-site_request_forgery

        This property is of type `bytes`, but it contains only ASCII
        characters. If a character string is required, there is no
        need to base64-encode it; just decode the byte string as
        UTF-8.

        .. versionchanged:: 3.2.2
           The xsrf token will now be have a random mask applied in every
           request, which makes it safe to include the token in pages
           that are compressed.  See http://breachattack.com for more
           information on the issue fixed by this change.  Old (version 1)
           cookies will be converted to version 2 when this method is called
           unless the ``xsrf_cookie_version`` `Application` setting is
           set to 1.

        .. versionchanged:: 4.3
           The ``xsrf_cookie_kwargs`` `Application` setting may be
           used to supply additional cookie options (which will be
           passed directly to `set_cookie`). For example,
           ``xsrf_cookie_kwargs=dict(httponly=True, secure=True)``
           will set the ``secure`` and ``httponly`` flags on the
           ``_xsrf`` cookie.

          or None if we generated a new token in this request.
        * token: the raw token data; random (non-ascii) bytes.
        * timestamp: the time this token was generated (will not be accurate

        field with all ``POST`` requests. If the two do not match, we
        reject the form submission as a potential forgery.

        The ``_xsrf`` value may be set as either a form field named ``_xsrf``
        or in a custom HTTP header named ``X-XSRFToken`` or ``X-CSRFToken``
        (the latter is accepted for compatibility with Django).

        See http://en.wikipedia.org/wiki/Cross-site_request_forgery

        .. versionchanged:: 3.2.2
           Added support for cookie version 2.  Both versions 1 and 2 are

        It defines the ``_xsrf`` input value, which we check on all POST
        requests to prevent cross-site request forgery. If you have set
        the ``xsrf_cookies`` application setting, you must include this
        HTML within all of your HTML forms.

        In a template, this method should be called with ``{% module
        xsrf_form_html() %}``

        See `check_xsrf_cookie()` above for more information.
        Tastatic_pathastatic_urlastatic_handler_classaStaticFileHandleramake_static_urlainclude_hostaprotocolu://ahostuReturns a static URL for the given relative static file path.

        This method requires you set the ``static_path`` setting in your
        application (which specifies the root directory of your static
        files).

        This method returns a versioned url (by default appending
        ``?v=<signature>``), which allows the static files to be
        cached indefinitely.  This can be disabled by passing
        ``include_version=False`` (in the default implementation;
        other static file implementations are not required to support
        this, but they may support other options).

        By default this method returns URLs relative to the current
        host, but if ``include_host`` is true the URL returned will be
        absolute.  If this handler has an ``include_host`` attribute,
        that value will be used as the default for all `static_url`
        calls that do not pass ``include_host`` as a keyword argument.

        acompute_etaguSets the response's Etag header using ``self.compute_etag()``.

        Note: no header will be set if ``compute_etag()`` returns ``None``.

        Returns ``True`` if the request's Etag matches and a 304 should be
        returned. For example::

            self.set_etag_header()
            if self.check_etag_header():
                self.set_status(304)
                return

        This method is called automatically when the request is finished,
        but may be called earlier for applications that override
        `compute_etag` and want to do an early check for ``If-None-Match``
        before completing the request.  The ``Etag`` header should be set
        (perhaps with `set_etag_header`) before calling this method.

    This decorator implies the following changes:

    * `.HTTPServerRequest.body` is undefined, and body arguments will not
      be included in `RequestHandler.get_argument`.
    * `RequestHandler.prepare` is called when the request headers have been
      read instead of after the entire body has been read.
    * The subclass must define a method ``data_received(self, data):``, which
      will be called zero or more times as data is available.  Note that
      if the request has an empty body, ``data_received`` may not be called.
    * ``prepare`` and ``data_received`` may return Futures (such as via
      ``@gen.coroutine``, in which case the next method will not be called
      until those futures have completed.
    * The regular HTTP method (``post``, ``put``, etc) will be called after
      the entire body has been read.

        This is a convenience alias for creating an `.HTTPServer` object and

        This is an instance method called during request processing,
        so it may raise `HTTPError` or use methods like

        are generated.

        This method may modify the path before returning it, but note that
        any such modifications will not be understood by `make_static_url`.

        (no ``settings`` argument); this is deliberate to ensure that
        ``abspath`` is able to stand on its own as a cache key.

        This method should either return a byte string or an iterator
        of byte strings.  The latter is preferred for large files
        as it helps reduce memory fragmentation.

        Return a positive number of seconds to make the result
        cacheable for that amount of time or 0 to mark resource as
        cacheable for an unspecified amount of time (subject to
        browser heuristics).

        By default returns cache expiry of 10 years for resources requested
        with ``v`` argument.
        Tastatic_url_prefixu/static/aget_versionu%s?v=%suConstructs a versioned url for the given path.

        This method may be overridden in subclasses (but note that it
        is a class method rather than an instance method).  Subclasses
        are only required to implement the signature
        ``make_static_url(cls, settings, path)``; other keyword
        arguments may be passed through `~RequestHandler.static_url`
        but are not standard.

        ``settings`` is the `Application.settings` dictionary.  ``path``
        is the static path being requested.  The url returned should be
        relative to the current host.

        ``include_version`` determines whether the generated URL should
        include the query string containing the version hash of the
        file corresponding to the given ``path``.

        uConverts a static URL path into a filesystem path.

        ``url_path`` is the path component of the URL with
        ``static_url_prefix`` removed.  The return value should be
        filesystem path relative to ``static_path``.

        This is the inverse of `make_static_url`.
        uGenerate the version string to be used in static URLs.

        ``settings`` is the `Application.settings` dictionary and ``path``
        is the relative location of the requested asset on the filesystem.
        The returned value should be a string, or ``None`` if no version
        could be determined.

        .. versionchanged:: 3.1
           This method was previously recommended for subclasses to override;
           `get_content_version` is now preferred as it allows the base
           class to handle caching of the result.

    If the user is not logged in, they will be redirected to the configured

    assume you know what you're doing and use it as-is.  If not, it
    will add a `next` parameter so the login page knows where to send

Thread-safety notes
-------------------

In general, methods on `RequestHandler` and elsewhere in Tornado are
not thread-safe. In particular, methods such as
`~RequestHandler.write()`, `~RequestHandler.finish()`, and
`~RequestHandler.flush()` must only be called from the main thread. If
you use multiple threads it is important to use `.IOLoop.add_callback`
to transfer control back to the main thread before finishing the
request, or to limit your use of other threads to
`.IOLoop.run_in_executor` and ensure that your callbacks running in
the executor do not refer to Tornado objects.

    Provides a binding between `Application` and `RequestHandler`.
    This implementation extends `~.routing.ReversibleRuleRouter` in a couple of ways:
        * it allows to use `RequestHandler` subclasses as `~.routing.Rule` target and
        * it allows to use a list/tuple of rules as `~.routing.Rule` target.
        ``process_rule`` implementation will substitute this list with an appropriate
        `_ApplicationRouter` instance.
    u_ApplicationRouter.__init__aruleu_ApplicationRouter.process_ruleatarget_paramsaHTTPMessageDelegateu_ApplicationRouter.get_target_delegateuA collection of request handlers that make up a web application.

    Instances of this class are callable and can be passed directly to
    HTTPServer to serve the application::

        application = web.Application([
            (r"/", MainPageHandler),
        ])
        http_server = httpserver.HTTPServer(application)
        http_server.listen(8080)

    The constructor for this class takes in a list of `~.routing.Rule`
    objects or tuples of values corresponding to the arguments of
    `~.routing.Rule` constructor: ``(matcher, target, [target_kwargs], [name])``,
    the values in square brackets being optional. The default matcher is
    `~.routing.PathMatches`, so ``(regexp, target)`` tuples can also be used
    instead of ``(PathMatches(regexp), target)``.

    A common routing target is a `RequestHandler` subclass, but you can also
    use lists of rules as a target, which create a nested routing configuration::

        application = web.Application([
            (HostMatches("example.com"), [
                (r"/", MainPageHandler),
                (r"/feed", FeedHandler),
            ]),
        ])

    In addition to this you can use nested `~.routing.Router` instances,
    `~.httputil.HTTPMessageDelegate` subclasses and callables as routing targets
    (see `~.routing` module docs for more information).

    When we receive requests, we iterate over the list in order and
    instantiate an instance of the first request class whose regexp
    matches the request path. The request class can be specified as
    either a class object or a (fully-qualified) name.

    A dictionary may be passed as the third element (``target_kwargs``)
    of the tuple, which will be used as keyword arguments to the handler's
    constructor and `~RequestHandler.initialize` method. This pattern
    is used for the `StaticFileHandler` in this example (note that a
    `StaticFileHandler` can be installed automatically with the
    static_path setting described below)::

        application = web.Application([
            (r"/static/(.*)", web.StaticFileHandler, {"path": "/var/www"}),
        ])

    We support virtual hosts with the `add_handlers` method, which takes in
    a host regular expression as the first argument::

        application.add_handlers(r"www\.myhost\.com", [
            (r"/article/([0-9]+)", ArticleHandler),
        ])

    If there's no match for the current request's host, then ``default_host``
    parameter value is matched against host regular expressions.


    .. warning::

       Applications that do not use TLS may be vulnerable to :ref:`DNS
       rebinding <dnsrebinding>` attacks. This attack is especially
       relevant to applications that only listen on ``127.0.0.1`` or
       other private networks. Appropriate host patterns must be used
       (instead of the default of ``r'.*'``) to prevent this risk. The
       ``default_host`` argument must not be used in applications that
       may be vulnerable to DNS rebinding.

    You can serve static files by sending the ``static_path`` setting
    as a keyword argument. We will serve those files from the
    ``/static/`` URI (this is configurable with the
    ``static_url_prefix`` setting), and we will serve ``/favicon.ico``
    and ``/robots.txt`` from the same directory.  A custom subclass of
    `StaticFileHandler` can be specified with the
    ``static_handler_class`` setting.

    Raising an `HTTPError` is a convenient alternative to calling
    `RequestHandler.send_error` since it automatically ends the
    current function.

    To customize the response sent with an `HTTPError`, override
    `RequestHandler.write_error`.

    :arg int status_code: HTTP status code.  Must be listed in
        `httplib.responses <http.client.responses>` unless the ``reason``
        keyword argument is given.
    :arg str log_message: Message to be written to the log for this error
        (will not be shown to the user unless the `Application` is in debug
        mode).  May contain ``%s``-style placeholders, which will be filled
        in with remaining positional parameters.
    :arg str reason: Keyword-only argument.  The HTTP "reason" phrase
        to pass in the status line along with ``status_code``.  Normally
        determined automatically from ``status_code``, but can be used
        to use a non-standard numeric code.
    Tl�nuHTTPError.__init__a__str__uHTTPError.__str__uAn exception that ends the request without producing an error response.

    When `Finish` is raised in a `RequestHandler`, the request will
    end (calling `RequestHandler.finish` if it hasn't already been
    called), but the error-handling methods (including
    `RequestHandler.write_error`) will not be called.

    If `Finish()` was created with no arguments, the pending response
    will be sent as-is. If `Finish()` was given an argument, that
    argument will be passed to `RequestHandler.finish()`.

    This can be a more convenient way to implement custom error pages
    than overriding ``write_error`` (especially in library code)::

        if self.current_user is None:
            self.set_status(401)
            self.set_header('WWW-Authenticate', 'Basic realm="something"')
            raise Finish()

    .. versionchanged:: 4.3
       Arguments passed to ``Finish()`` will be passed on to
       `RequestHandler.finish`.
    uException raised by `RequestHandler.get_argument`.

    This is a subclass of `HTTPError`, so if it is uncaught a 400 response
    code will be used instead of 500 (and a stack trace will not be logged).

    .. versionadded:: 3.1
    uMissingArgumentError.__init__uGenerates an error response with ``status_code`` for all requests.uErrorHandler.initializeuErrorHandler.prepareuErrorHandler.check_xsrf_cookieaRedirectHandleruRedirects the client to the given URL for all GET requests.

    You should provide the keyword argument ``url`` to the handler, e.g.::

        application = web.Application([
            (r"/oldpath", web.RedirectHandler, {"url": "/newpath"}),
        ])

    `RedirectHandler` supports regular expression substitutions. E.g., to
    swap the first and second parts of a path while preserving the remainder::

        application = web.Application([
            (r"/(.*?)/(.*?)/(.*)", web.RedirectHandler, {"url": "/{1}/{0}/{2}"}),
        ])

    The final URL is formatted with `str.format` and the substrings that match
    the capturing groups. In the above example, a request to "/a/b/c" would be
    formatted like::

        str.format("/{1}/{0}/{2}", "a", "b", "c")  # -> "/b/a/c"

    Use Python's :ref:`format string syntax <formatstrings>` to customize how
    values are substituted.

    .. versionchanged:: 4.5
       Added support for substitutions into the destination URL.

    .. versionchanged:: 5.0
       If any query arguments are present, they will be copied to the
       destination URL.
    uRedirectHandler.initializeuRedirectHandler.getuA simple handler that can serve static content from a directory.

    A `StaticFileHandler` is configured automatically if you pass the
    ``static_path`` keyword argument to `Application`.  This handler
    can be customized with the ``static_url_prefix``, ``static_handler_class``,
    and ``static_handler_args`` settings.

    To map an additional path to this handler for a static data directory
    you would add a line to your application like::

        application = web.Application([
            (r"/content/(.*)", web.StaticFileHandler, {"path": "/var/www"}),
        ])

    The handler constructor requires a ``path`` argument, which specifies the
    local root directory of the content to be served.

    Note that a capture group in the regex is required to parse the value for
    the ``path`` argument to the get() method (different than the constructor
    argument above); see `URLSpec` for details.

    To serve a file like ``index.html`` automatically when a directory is
    requested, set ``static_handler_args=dict(default_filename="index.html")``
    in your application settings, or add ``default_filename`` as an initializer
    argument for your ``StaticFileHandler``.

    To maximize the effectiveness of browser caching, this class supports
    versioned urls (by default using the argument ``?v=``).  If a version
    is given, we instruct the browser to cache this file indefinitely.
    `make_static_url` (also available as `RequestHandler.static_url`) can
    be used to construct a versioned url.

    This handler is intended primarily for use in development and light-duty
    file serving; for heavy traffic it will be more efficient to use
    a dedicated static file server (such as nginx or Apache).  We support
    the HTTP ``Accept-Ranges`` mechanism to return partial content (because
    some browsers require this functionality to be present to seek in
    HTML5 audio or video).

    **Subclassing notes**

    This class is designed to be extensible by subclassing, but because
    of the way static urls are generated with class methods rather than
    instance methods, the inheritance patterns are somewhat unusual.
    Be sure to use the ``@classmethod`` decorator when overriding a
    class method.  Instance methods may use the attributes ``self.path``
    ``self.absolute_path``, and ``self.modified``.

    Subclasses should only override methods discussed in this section;
    overriding other methods is error-prone.  Overriding
    ``StaticFileHandler.get`` is particularly problematic due to the
    tight coupling with ``compute_etag`` and other methods.

    To change the way static urls are generated (e.g. to match the behavior
    of another server or CDN), override `make_static_url`, `parse_url_path`,
    `get_cache_time`, and/or `get_version`.

    To replace all interaction with the filesystem (e.g. to serve
    static content from a database), override `get_content`,
    `get_content_size`, `get_modified_time`, `get_absolute_path`, and
    `validate_absolute_path`.

    .. versionchanged:: 3.1

    The fallback is a callable object that accepts an
    `~.httputil.HTTPServerRequest`, such as an `Application` or
    `tornado.wsgi.WSGIContainer`.  This is most useful to use both
    Tornado ``RequestHandlers`` and WSGI in the same server.  Typical
    usage::

        wsgi_app = tornado.wsgi.WSGIContainer(
            django.core.handlers.wsgi.WSGIHandler())
        application = tornado.web.Application([
            (r"/foo", FooHandler),

    uFallbackHandler.initializeuFallbackHandler.prepareuA transform modifies the result of an HTTP request (e.g., GZip encoding)

    UI modules often execute additional queries, and they can include

    {% module Template("foo.html") %} is similar to {% include "foo.html" %},
    but the module version gets its own namespace (with kwargs passed to
    Template()) instead of inheriting the outer template's namespace.

    Templates rendered through this module also get access to UIModule's
    automatic JavaScript/CSS features.  Simply call set_resources
    inside the template and give it keyword arguments corresponding to
    the methods on UIModule: {{ set_resources(js_files=static_url("my.js")) }}
    Note that these resources are output once per template file, not once
    per instantiation of the template, so they must not depend on
    any arguments to the template.

        The data argument allows a small amount of data (up to 125
        bytes) to be sent as a part of the ping message. Note that not
        all websocket implementations expose this data to
        applications.

        Consider using the ``websocket_ping_interval`` application
        setting instead of sending pings manually.

        .. versionchanged:: 5.1

           The data argument is now optional.

        acloseuCloses this Web Socket.

        Once the close handshake is successful the socket will be closed.

        ``code`` may be a numeric status code, taken from the values
        defined in `RFC 6455 section 7.4.1
        <https://tools.ietf.org/html/rfc6455#section-7.4.1>`_.
        ``reason`` may be a textual message about why the connection is
        closing.  These values are made available to the client, but are
        not otherwise interpreted by the websocket protocol.

        .. versionchanged:: 4.0

           Added the ``code`` and ``reason`` arguments.
        aurlparseanetlocTaHostuOverride to enable support for allowing alternate origins.

        The ``origin`` argument is the value of the ``Origin`` HTTP
        header, the url responsible for initiating this request.  This
        method is not called for clients that do not send this header;
        such requests are always allowed (because all browsers that
        implement WebSockets support this header, and non-browser
        clients do not have the same cross-site security concerns).

        Should return ``True`` to accept the request or ``False`` to
        reject it. By default, rejects all requests with an origin on
        a host other than this one.

        This is a security protection against cross site scripting attacks on
        browsers, since WebSockets are allowed to bypass the usual same-origin
        policies and don't use CORS headers.

        .. warning::

           This is an important security measure; don't disable it
           without understanding the security implications. In
           particular, if your authentication is cookie-based, you
           must either restrict the origins allowed by
           ``check_origin()`` or implement your own XSRF-like
           protection for websocket connections. See `these
           <https://www.christian-schneider.net/CrossSiteWebSocketHijacking.html>`_
           `articles
           <https://devcenter.heroku.com/articles/websocket-security>`_
           for more.

        To accept all cross-origin traffic (which was the default prior to
        Tornado 4.0), simply override this method to always return ``True``::

            def check_origin(self, origin):
                return True

        To allow connections from any subdomain of your site, you might
        do something like::

            def check_origin(self, origin):
                parsed_origin = urllib.parse.urlparse(origin)
                return parsed_origin.netloc.endswith(".mydomain.com")

        .. versionadded:: 4.0

        aset_nodelayuSet the no-delay flag for this stream.

        By default, small messages may be delayed and/or combined to minimize
        the number of packets sent.  This can sometimes cause 200-500ms delays
        due to the interaction between Nagle's algorithm and TCP delayed
        ACKs.  To reduce this delay (at the expense of possibly increasing
        bandwidth usage), call ``self.set_nodelay(True)`` once the websocket
        connection is established.

        See `.BaseIOStream.set_nodelay` for additional details.

    ``compression_options`` is interpreted in the same way as the
    return value of `.WebSocketHandler.get_compression_options`.

    The connection supports two styles of operation. In the coroutine
    style, the application typically calls
    `~.WebSocketClientConnection.read_message` in a loop::

        conn = yield websocket_connect(url)
        while True:
            msg = yield conn.read_message()
            if msg is None: break
            # Do something with msg

    In the callback style, pass an ``on_message_callback`` to
    ``websocket_connect``. In both styles, a message of ``None``
    indicates that the connection has been closed.

    ``subprotocols`` may be a list of strings specifying proposed
    subprotocols. The selected protocol may be found on the
    ``selected_subprotocol`` attribute of the connection object
    when the connection is complete.

    uImplementation of the WebSocket protocol.

`WebSockets <http://dev.w3.org/html5/websockets/>`_ allow for bidirectional
communication between the browser and server.

WebSockets are supported in the current versions of all major browsers,
although older versions that do not support WebSockets are still in use
(refer to http://caniuse.com/websockets for details).

This module implements the final version of the WebSocket protocol as
defined in `RFC 6455 <http://tools.ietf.org/html/rfc6455>`_.  Certain
browser versions (notably Safari 5.x) implemented an earlier draft of
the protocol (known as "draft 76") and are not compatible with this module.

.. versionchanged:: 4.0
   Removed support for the draft 76 protocol version.

    See http://dev.w3.org/html5/websockets/ for details on the
    JavaScript interface.  The protocol is specified at
    http://tools.ietf.org/html/rfc6455.

    Here is an example WebSocket handler that echos back all received messages
    back to the client:

    .. testcode::

      class EchoWebSocket(tornado.websocket.WebSocketHandler):
          def open(self):
              print("WebSocket opened")

          def on_message(self, message):
              self.write_message(u"You said: " + message)

          def on_close(self):
              print("WebSocket closed")

    .. testoutput::
       :hide:

    WebSockets are not standard HTTP connections. The "handshake" is
    HTTP, but after the handshake, the protocol is
    message-based. Consequently, most of the Tornado HTTP facilities
    are not available in handlers of this type. The only communication
    methods available to you are `write_message()`, `ping()`, and
    `close()`. Likewise, your request handler class should implement
    `open()` method rather than ``get()`` or ``post()``.

    If you map the handler above to ``/websocket`` in your application, you can
    invoke it in JavaScript with::

      var ws = new WebSocket("ws://localhost:8888/websocket");
      ws.onopen = function() {
         ws.send("Hello, world");
      };
      ws.onmessage = function (evt) {
         alert(evt.data);
      };

    This script pops up an alert box that says "You said: Hello, world".

    Web browsers allow any site to open a websocket connection to any other,
    instead of using the same-origin policy that governs other network
    access from JavaScript.  This can be surprising and is a potential
    security hole, so since Tornado 4.0 `WebSocketHandler` requires
    applications that wish to receive cross-origin websockets to opt in
    by overriding the `~WebSocketHandler.check_origin` method (see that
    method's docs for details).  Failure to do so is the most likely
    cause of 403 errors when making a websocket connection.

    When using a secure websocket connection (``wss://``) with a self-signed
    certificate, the connection from a browser may fail because it wants
    to show the "accept this certificate" dialog but has nowhere to show it.
    You must first visit a regular HTML page using the same certificate
    to accept it before the websocket connection will succeed.

    If the application setting ``websocket_ping_interval`` has a non-zero
    value, a ping will be sent periodically, and the connection will be
    closed if a response is not received before the ``websocket_ping_timeout``.

    Messages larger than the ``websocket_max_message_size`` application setting
    (default 10MiB) will not be accepted.

    .. versionchanged:: 4.5
       Added ``websocket_ping_interval``, ``websocket_ping_timeout``, and
       ``websocket_max_message_size``.

        ``subprotocols`` is a list of strings identifying the
        subprotocols proposed by the client.  This method may be
        overridden to return one of those strings to select it, or
        ``None`` to not select a subprotocol.

        Failure to select a subprotocol does not automatically abort
        the connection, although clients may close the connection if
        none of their proposed subprotocols was selected.

        The list may be empty, in which case this method must return
        None. This method is always called exactly once even if no
        subprotocols were proposed so that the handler can be advised
        of this fact.

        .. versionchanged:: 5.1

           Previously, this method was called with a list containing
           an empty string instead of an empty list if no subprotocols
           were proposed by the client.
        uWebSocketHandler.select_subprotocoluWebSocketHandler.selected_subprotocoluOverride to return compression options for the connection.

        If this method returns None (the default), compression will
        be disabled.  If it returns a dict (even an empty one), it
        will be enabled.  The contents of the dict may be used to
        control the following compression options:

        ``compression_level`` specifies the compression level.

        ``mem_level`` specifies the amount of memory used for the internal compression state.

         These parameters are documented in details here:
         https://docs.python.org/3.6/library/zlib.html#zlib.compressobj

        .. versionadded:: 4.1

        .. versionchanged:: 4.5

           Added ``compression_level`` and ``mem_level``.
        uWebSocketHandler.get_compression_optionsuInvoked when a new WebSocket is opened.

        The arguments to `open` are extracted from the `tornado.web.URLSpec`
        regular expression, just like the arguments to
        `tornado.web.RequestHandler.get`.

        `open` may be a coroutine. `on_message` will not be called until
        `open` has returned.

        .. versionchanged:: 5.1

           ``open`` may be a coroutine.

        If the connection was closed cleanly and a status code or reason
        phrase was supplied, these values will be available as the attributes
        ``self.close_code`` and ``self.close_reason``.

        .. versionchanged:: 4.0

    A ``dict`` like container for storing HTTP Headers.

    Field names are stored and compared case-insensitively in compliance with
    RFC 7230. Iteration provides the first case-sensitive key seen for each
    case-insensitive pair.

    Using ``__setitem__`` syntax overwrites fields that compare equal
    case-insensitively in order to maintain ``dict``'s api. For fields that
    compare equal, instead create a new ``HTTPHeaderDict`` and use ``.add``
    in a loop.

    If multiple fields that are equal case-insensitively are passed to the
    constructor or ``.update``, the behavior is undefined and some will be
    lost.

        Getter method to remove any trailing dots that indicate the hostname is an FQDN.

        In general, SSL certificates don't include the trailing dot indicating a
        fully-qualified domain name, and thus, they don't validate properly when
        checked against a domain name that includes the dot. In addition, some
        servers may not expect to receive the trailing dot when provided.

        However, the hostname with trailing dot is critical to DNS resolution; doing a
        lookup with the trailing dot will properly only resolve the appropriate FQDN,
        whereas a lookup without a trailing dot will search the system's search domain
        list. Thus, it's important to keep the original host around for use only in
        those cases where it's appropriate (i.e., when doing DNS lookup to establish the
        actual TCP connection across which we're going to send HTTP requests).
        u
        Setter for the `host` property.

        We assume that only urllib3 uses the _dns_host attribute; httplib itself
        only uses `host`, and it seems reasonable that other libraries follow suit.

    Based on httplib.HTTPConnection but provides an extra constructor
    backwards-compatibility layer between older and newer Pythons.

    Additional keyword parameters are used to configure attributes of the connection.
    Accepted parameters include:

      - ``strict``: See the documentation on :class:`urllib3.connectionpool.HTTPConnectionPool`
      - ``source_address``: Set the source address for the current connection.
      - ``socket_options``: Set specific options on the underlying socket. If not specified, then
        defaults are loaded from ``HTTPConnection.default_socket_options`` which includes disabling
        Nagle's algorithm (sets TCP_NODELAY to 1) unless the connection is behind a proxy.

        For example, if you wish to enable TCP Keep Alive in addition to the defaults,
        you might pass::

            HTTPConnection.default_socket_options + [
                (socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1),
            ]

        Or you may want to disable the defaults by passing an empty list (e.g., ``[]``).

        Get a connection from the pool and perform an HTTP request. This is the
        lowest level call for making a request, so you'll need to specify all
        the raw details.

        .. note::

           More commonly, it's appropriate to use a convenience method provided
           by :class:`.RequestMethods`, such as :meth:`request`.

        .. note::

           `release_conn` will only behave as expected if
           `preload_content=False` because we want to make
           `preload_content=False` the default behaviour someday soon without
           breaking backwards compatibility.

        :param method:
            HTTP request method (such as GET, POST, PUT, etc.)

        :param body:
            Data to send in the request body (useful for creating
            POST requests, see HTTPConnectionPool.post_url for
            more convenience).

        :param headers:
            Dictionary of custom headers to send, such as User-Agent,
            If-None-Match, etc. If None, pool headers are used. If provided,
            these headers completely replace any pool-specific headers.

        :param retries:
            Configure the number of retries to allow before raising a
            :class:`~urllib3.exceptions.MaxRetryError` exception.

            Pass ``None`` to retry until you receive a response. Pass a
            :class:`~urllib3.util.retry.Retry` object for fine-grained control
            over different types of retries.
            Pass an integer number to retry connection errors that many times,
            but no other types of errors. Pass zero to never retry.

            If ``False``, then retries are disabled and any exception is raised
            immediately. Also, instead of raising a MaxRetryError on redirects,
            the redirect response will be returned.

        :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int.

        :param redirect:
            If True, automatically handle redirects (status codes 301, 302,
            303, 307, 308). Each redirect counts as a retry. Disabling retries
            will disable redirect, too.

        :param assert_same_host:
            If ``True``, will make sure that the host of the pool requests is
            consistent else will raise HostChangedError. When False, you can
            use the pool on an HTTP proxy and request foreign hosts.

        :param timeout:
            If specified, overrides the default timeout for this one
            request. It may be a float (in seconds) or an instance of
            :class:`urllib3.util.Timeout`.

        :param pool_timeout:
            If set and the pool is set to block=True, then this method will
            block for ``pool_timeout`` seconds and raise EmptyPoolError if no
            connection is available within the time period.

        :param release_conn:
            If False, then the urlopen call will not release the connection
            back into the pool once a response is received (but will release if
            you read the entire contents of the response such as when
            `preload_content=True`). This is useful if you're not preloading
            the response's content immediately. You will need to call
            ``r.release_conn()`` on the response ``r`` to return the connection
            back into the pool. If None, it takes the value of
            ``response_kw.get('preload_content', True)``.

        :param chunked:
            If True, urllib3 will send the body using chunked transfer
            encoding. Otherwise, urllib3 will send the body using the standard
            content-length form. Defaults to False.

        :param int body_pos:
            Position to seek to in file-like body in the event of a retry or
            redirect. Typically this won't need to be set because urllib3 will
            auto-populate the value when needed.

        :param \**response_kw:
            Additional parameters are passed to
            :meth:`urllib3.response.HTTPResponse.from_httplib`

        Establish tunnel connection early, because otherwise httplib

        Called right before a request is made, after the socket is created.
        lPahttpsu
    Given a url, return an :class:`.ConnectionPool` instance of its host.

    This is a shortcut for not having to parse out the scheme, host, and port
    of the url before creating an :class:`.ConnectionPool` instance.

    :param url:
        Absolute URL string that must include the scheme. Port is optional.

    :param \**kw:
        Passes additional parameters to the constructor of the appropriate
        :class:`.ConnectionPool`. Useful for specifying things like
        timeout, maxsize, headers, etc.

    Example::

        >>> conn = connection_from_url('http://google.com/')
        >>> r = conn.request('GET', '/')

    Thread-safe connection pool for one host.

    :param host:
        Host used for this HTTP Connection (e.g. "localhost"), passed into
        :class:`httplib.HTTPConnection`.

    :param port:
        Port used for this HTTP Connection (None is equivalent to 80), passed
        into :class:`httplib.HTTPConnection`.

    :param strict:
        Causes BadStatusLine to be raised if the status line can't be parsed
        as a valid HTTP/1.0 or 1.1 status line, passed into
        :class:`httplib.HTTPConnection`.

        .. note::
           Only works in Python 2. This parameter is ignored in Python 3.

    :param timeout:
        Socket timeout in seconds for each individual connection. This can
        be a float or integer, which sets the timeout for the HTTP request,
        or an instance of :class:`urllib3.util.Timeout` which gives you more
        fine-grained control over request timeouts. After the constructor has
        been parsed, this is always a `urllib3.util.Timeout` object.

    :param maxsize:
        Number of connections to save that can be reused. More than 1 is useful
        in multithreaded situations. If ``block`` is set to False, more
        connections will be created but they will not be saved once they've
        been used.

    :param block:
        If set to True, no more than ``maxsize`` connections will be used at
        a time. When no free connections are available, the call will block
        until a connection has been released. This is a useful side effect for
        particular multithreaded situations where one does not want to use more
        than maxsize connections per host to prevent flooding.

    :param headers:
        Headers to include with all requests, unless other headers are given
        explicitly.

    :param retries:
        Retry configuration to use by default with requests in this pool.

    :param _proxy:
        Parsed proxy URL, should not be used directly, instead, see
        :class:`urllib3.connectionpool.ProxyManager`"

    :param _proxy_headers:
        A dictionary with proxy headers, should not be used directly,
        instead, see :class:`urllib3.connectionpool.ProxyManager`"

    :param \**conn_kw:
        Additional parameters are used to create fresh :class:`urllib3.connection.HTTPConnection`,
        :class:`urllib3.connection.HTTPSConnection` instances.

    Same as :class:`.HTTPConnectionPool`, but HTTPS.

    When Python is compiled with the :mod:`ssl` module, then
    :class:`.VerifiedHTTPSConnection` is used, which *can* verify certificates,
    instead of :class:`.HTTPSConnection`.

    :class:`.VerifiedHTTPSConnection` uses one of ``assert_fingerprint``,
    ``assert_hostname`` and ``host`` in this order to verify connections.
    If ``assert_hostname`` is False, no verification is done.

    The ``key_file``, ``cert_file``, ``cert_reqs``, ``ca_certs``,
    ``ca_cert_dir``, ``ssl_version``, ``key_password`` are only used if :mod:`ssl`
    is available and are fed into :meth:`urllib3.util.ssl_wrap_socket` to upgrade
    the connection socket into an SSL socket.

This module provides a pool manager that uses Google App Engine's
`URLFetch Service <https://cloud.google.com/appengine/docs/python/urlfetch>`_.

Example usage::

    from urllib3 import PoolManager
    from urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox

    if is_appengine_sandbox():
        # AppEngineManager uses AppEngine's URLFetch API behind the scenes
        http = AppEngineManager()
    else:
        # PoolManager uses a socket-level API behind the scenes
        http = PoolManager()

    r = http.request('GET', 'https://google.com/')

There are `limitations <https://cloud.google.com/appengine/docs/python/urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be
the best choice for your application. There are three options for using
urllib3 on Google App Engine:

1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is
   cost-effective in many circumstances as long as your usage is within the
   limitations.
2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets.
   Sockets also have `limitations and restrictions
   <https://cloud.google.com/appengine/docs/python/sockets/   #limitations-and-restrictions>`_ and have a lower free quota than URLFetch.
   To use sockets, be sure to specify the following in your ``app.yaml``::

        env_variables:
            GAE_USE_SOCKETS_HTTPLIB : 'true'

3. If you are using `App Engine Flexible
<https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard
:class:`PoolManager` without any configuration or special environment variables.

    Connection manager for Google App Engine sandbox applications.

    This manager uses the URLFetch service directly instead of using the
    emulated httplib, and is subject to URLFetch limitations as described in
    the App Engine documentation `here
    <https://cloud.google.com/appengine/docs/python/urlfetch>`_.

    Notably it will raise an :class:`AppEnginePlatformError` if:
        * URLFetch is not available.
        * If you attempt to use this on App Engine Flexible, as full socket
          support is available.
        * If a request size is more than 10 megabytes.
        * If a response size is more than 32 megabtyes.
        * If you use an unsupported request method such as OPTIONS.

    Beyond those cases, it will raise normal urllib3 errors.

    Cryptography produces a dNSName as a unicode string that was idna-decoded
    from ASCII bytes. We need to idna-encode that string to get it back, and
    then on Python 3 we also need to convert to unicode via UTF-8 (the stdlib
    uses PyUnicode_FromStringAndSize on it, which decodes via UTF-8).

    If the name cannot be idna-encoded then we return None signalling that
    the name given should be skipped.

SSL with SNI_-support for Python 2. Follow these instructions if you would
like to verify SSL certificates in Python 2. Note, the default libraries do
*not* do certificate checking; you need to do additional work to validate
certificates yourself.

This needs the following packages installed:

* pyOpenSSL (tested with 16.0.0)
* cryptography (minimum 1.3.4, from pyopenssl)
* idna (minimum 2.0, from cryptography)

However, pyopenssl depends on cryptography, which depends on idna, so while we
use all three directly here we end up having relatively few packages required.

You can install them with the following command:

    pip install pyopenssl cryptography idna

To activate certificate checking, call
:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
before you begin making HTTP requests. This can be done in a ``sitecustomize``
module, or at any other time before your application begins using ``urllib3``,
like this::

    try:
        import urllib3.contrib.pyopenssl
        urllib3.contrib.pyopenssl.inject_into_urllib3()
    except ImportError:
        pass

Now you can use :mod:`urllib3` as you normally would, and it will support SNI
when the required modules are installed.

Activating this module also has the positive side effect of disabling SSL/TLS
compression in Python 2 (see `CRIME attack`_).

If you want to configure the default list of supported cipher suites, you can
set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable.

This module contains provisional support for SOCKS proxies from within
urllib3. This module supports SOCKS4, SOCKS4A (an extension of SOCKS4), and
SOCKS5. To enable its functionality, either install PySocks or install this
module with the ``socks`` extra.

The SOCKS implementation supports the full range of urllib3 features. It also
supports the following SOCKS features:

- SOCKS4A (``proxy_url='socks4a://...``)
- SOCKS4 (``proxy_url='socks4://...``)
- SOCKS5 with remote DNS (``proxy_url='socks5h://...``)
- SOCKS5 with local DNS (``proxy_url='socks5://...``)
- Usernames and passwords for the SOCKS proxy

 .. note::
    It is recommended to use ``socks5h://`` or ``socks4a://`` schemes in
    your ``proxy_url`` to ensure that DNS resolution is done from the remote
    server instead of client-side when connecting to a domain name.

SOCKS4 supports IPv4 and domain names with the SOCKS4A extension. SOCKS5
supports IPv4, IPv6, and domain names.

When connecting to a SOCKS4 proxy the ``username`` portion of the ``proxy_url``
will be sent as the ``userid`` section of the SOCKS request::

    proxy_url="socks4a://<userid>@proxy-host"

When connecting to a SOCKS5 proxy the ``username`` and ``password`` portion
of the ``proxy_url`` will be sent as the username/password to authenticate
with the proxy::

    proxy_url="socks5h://<username>:<password>@proxy-host"

IaheadersuClasses extending RequestMethods must implement their own ``urlopen`` method.aupperarequest_urla_encode_url_methodsarequest_encode_urlafieldsarequest_encode_bodyu
        Make a request using :meth:`urlopen` with the appropriate encoding of
        ``fields`` based on the ``method`` used.

        This is a convenience method that requires the least amount of manual
        effort. It can be used in most situations, while still having the
        option to drop down to more specific methods when necessary, such as
        :meth:`request_encode_url`, :meth:`request_encode_body`,
        or even the lowest level :meth:`urlopen`.
        w?aurlencodeaselfaurlopenu
        Make a request using :meth:`urlopen` with the ``fields`` encoded in
        the url. This is useful for request methods like GET, HEAD, DELETE, etc.
        DaheadersDabodyurequest got values for both 'fields' and 'body', can only specify one.aencode_multipart_formdataTaboundaryutoo many values to unpack (expected 2)uapplication/x-www-form-urlencodeduContent-Typeaextra_kwaupdateu
        Make a request using :meth:`urlopen` with the ``fields`` encoded in
        the body. This is useful for request methods like POST, PUT, PATCH, etc.

        When ``encode_multipart=True`` (default), then
        :meth:`urllib3.filepost.encode_multipart_formdata` is used to encode
        the payload with the appropriate content type. Otherwise
        :meth:`urllib.urlencode` is used with the
        'application/x-www-form-urlencoded' content type.

        Multipart encoding must be used when posting files, and it's reasonably
        safe to use it in other times too. However, it may break request
        signing, such as with OAuth.

        Supports an optional ``fields`` parameter of key/value strings AND
        key/filetuple. A filetuple is a (filename, data, MIME type) tuple where
        the MIME type is optional. For example::

            fields = {
                'foo': 'bar',
                'fakefile': ('foofile.txt', 'contents of foofile'),
                'realfile': ('barfile.txt', open('realfile').read()),
                'typedfile': ('bazfile.bin', open('bazfile').read(),
                              'image/jpeg'),
                'nonamefile': 'contents of nonamefile field',
            }

        When uploading a file, providing a filename (the first parameter of the
        tuple) is optional but recommended to best mimic behavior of browsers.

        Note that if ``headers`` are supplied, the 'Content-Type' header will
        be overwritten because it depends on the dynamic random boundary string
        which is used to compose the body of the request. The random boundary
        string can be explicitly set with the ``multipart_boundary`` parameter.

    Convenience mixin for classes who implement a :meth:`urlopen` method, such
    as :class:`~urllib3.connectionpool.HTTPConnectionPool` and
    :class:`~urllib3.poolmanager.PoolManager`.

    Provides behavior for making common types of HTTP request methods and
    decides which type of request field encoding to use.

    Specifically,

    :meth:`.request_encode_url` is for sending requests whose fields are
    encoded in the URL (such as GET, HEAD, DELETE).

    :meth:`.request_encode_body` is for sending requests whose fields are
    encoded in the *body* of the request using multipart or www-form-urlencoded
    (such as for POST, PUT, PATCH).

    :meth:`.request` is for making any kind of request, it will look up the
    appropriate encoding format and use one of the above two methods to make
    the request.

    HTTP Response container.

    Backwards-compatible to httplib's HTTPResponse but the response ``body`` is
    loaded and decoded on-demand when the ``data`` property is accessed.  This
    class is also compatible with the Python standard library's :mod:`io`
    module, and can hence be treated as a readable object in the context of that
    framework.

    Extra parameters for behaviour not present in httplib.HTTPResponse:

    :param preload_content:
        If True, the response's body will be preloaded during construction.

    :param decode_content:
        If True, will attempt to decode the body based on the

    :param original_response:
        When this HTTPResponse wrapper is generated from an httplib.HTTPResponse
        object, it's convenient to include the original for debug purposes. It's
        otherwise unused.

    :param keep_alive:
        If ``True``, adds 'connection: keep-alive' header.

    :param accept_encoding:
        Can be a boolean, list, or string.
        ``True`` translates to 'gzip,deflate'.
        List will get joined by comma.
        String will be used as provided.

    :param user_agent:
        String representing the user-agent you want, such as
        "python-urllib3/0.6"

    Each retry attempt will create a new Retry object with updated values, so
    they can be safely reused.

    Retries can be defined as a default for a pool::

        retries = Retry(connect=5, read=2, redirect=5)
        http = PoolManager(retries=retries)
        response = http.request('GET', 'http://example.com/')

    Or per-request (which overrides the default for the pool)::

        response = http.request('GET', 'http://example.com/', retries=Retry(10))

    Retries can be disabled by passing ``False``::

        response = http.request('GET', 'http://example.com/', retries=False)

    Errors will be wrapped in :class:`~urllib3.exceptions.MaxRetryError` unless
    retries are disabled, in which case the causing exception will be raised.

    :param int total:
        Total number of retries to allow. Takes precedence over other counts.

        Set to ``None`` to remove this constraint and fall back on other
        counts. It's a good idea to set this to some sensibly-high value to
        account for unexpected edge cases and avoid infinite retry loops.

        Set to ``0`` to fail on the first retry.

        Set to ``False`` to disable and imply ``raise_on_redirect=False``.

    :param int connect:
        How many connection-related errors to retry on.

        These are errors raised before the request is sent to the remote server,
        which we assume has not triggered the server to process the request.

        Set to ``0`` to fail on the first retry of this type.

    :param int read:
        How many times to retry on read errors.

        These errors are raised after the request was sent to the server, so the
        request may have side-effects.

        Set to ``0`` to fail on the first retry of this type.

    :param int redirect:
        How many redirects to perform. Limit this to avoid infinite redirect
        loops.

        A redirect is a HTTP response with a status code 301, 302, 303, 307 or
        308.

        Set to ``0`` to fail on the first retry of this type.

        Set to ``False`` to disable and imply ``raise_on_redirect=False``.

    :param int status:
        How many times to retry on bad status codes.

        These are retries made on responses, where status code matches
        ``status_forcelist``.

        Set to ``0`` to fail on the first retry of this type.

    :param iterable method_whitelist:
        Set of uppercased HTTP method verbs that we should retry on.

        By default, we only retry on methods which are considered to be
        idempotent (multiple requests with the same parameters end with the
        same state). See :attr:`Retry.DEFAULT_METHOD_WHITELIST`.

        Set to a ``False`` value to retry on any verb.

    :param iterable status_forcelist:
        A set of integer HTTP status codes that we should force a retry on.
        A retry is initiated if the request method is in ``method_whitelist``
        and the response status code is in ``status_forcelist``.

        By default, this is disabled with ``None``.

    :param float backoff_factor:
        A backoff factor to apply between attempts after the second try
        (most errors are resolved immediately by a second try without a
        delay). urllib3 will sleep for::

            {backoff factor} * (2 ** ({number of total retries} - 1))

        seconds. If the backoff_factor is 0.1, then :func:`.sleep` will sleep
        for [0.0s, 0.2s, 0.4s, ...] between retries. It will never be longer
        than :attr:`Retry.BACKOFF_MAX`.

        By default, backoff is disabled (set to 0).

    :param bool raise_on_redirect: Whether, if the number of redirects is
        exhausted, to raise a MaxRetryError, or to return a response with a
        response code in the 3xx range.

    :param bool raise_on_status: Similar meaning to ``raise_on_redirect``:
        whether we should raise an exception, or return a response,
        if status falls in ``status_forcelist`` range and retries have
        been exhausted.

    :param tuple history: The history of the request encountered during
        each call to :meth:`~Retry.increment`. The list is in the order
        the requests occurred. Each list item is of class :class:`RequestHistory`.

    :param bool respect_retry_after_header:
        Whether to respect Retry-After header on status codes defined as
        :attr:`Retry.RETRY_AFTER_STATUS_CODES` or not.

    :param iterable remove_headers_on_redirect:
        Sequence of headers to remove from the request when a response
        indicating a redirect is returned before firing off the redirected
        request.

    By default, this function does a lot of the same work that
    ``ssl.create_default_context`` does on Python 3.4+. It:

    - Disables SSLv2, SSLv3, and compression
    - Sets a restricted set of server ciphers

    If you wish to enable SSLv3, you can do::

        from urllib3.util import ssl_
        context = ssl_.create_urllib3_context()
        context.options &= ~ssl_.OP_NO_SSLv3

    You can do the same to enable compression (substituting ``COMPRESSION``
    for ``SSLv3`` in the last line above).

    :param ssl_version:
        The desired protocol version to use. This will default to
        PROTOCOL_SSLv23 which will negotiate the highest protocol that both
        the server and your installation of OpenSSL support.
    :param cert_reqs:
        Whether to require the certificate verification. This defaults to
        ``ssl.CERT_REQUIRED``.
    :param options:

        This assumes some time has elapsed in the connection timeout and
        computes the read timeout appropriately.

        If self.total is set, the read timeout is dependent on the amount of
        time taken by the connect timeout. If the connection time has not been
        established, a :exc:`~urllib3.exceptions.TimeoutStateError` will be
        raised.

        :return: Value to use for the read timeout.

    Timeouts can be defined as a default for a pool::

        timeout = Timeout(connect=2.0, read=7.0)
        http = PoolManager(timeout=timeout)
        response = http.request('GET', 'http://example.com/')

    Or per-request (which overrides the default for the pool)::

        response = http.request('GET', 'http://example.com/', timeout=Timeout(10))

    Timeouts can be disabled by setting all the parameters to ``None``::

        no_timeout = Timeout(connect=None, read=None)
        response = http.request('GET', 'http://example.com/, timeout=no_timeout)


    :param total:
        This combines the connect and read timeouts into one; the read timeout
        will be set to the time leftover from the connect attempt. In the
        event that both a connect timeout and a total are specified, or a read
        timeout and a total are specified, the shorter timeout will be applied.

        Defaults to None.

    :type total: integer, float, or None

    :param connect:
        The maximum amount of time (in seconds) to wait for a connection
        attempt to a server to succeed. Omitting the parameter will default the
        connect timeout to the system default, probably `the global default
        timeout in socket.py
        <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_.
        None will set an infinite timeout for connection attempts.

    :type connect: integer, float, or None

    :param read:
        The maximum amount of time (in seconds) to wait between consecutive
        read operations for a response from the server. Omitting the parameter
        will default the read timeout to the system default, probably `the
        global default timeout in socket.py
        <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_.
        None will set an infinite timeout.

    :type read: integer, float, or None

    .. note::

        Many factors can affect the total amount of time for urllib3 to return
        an HTTP response.

        For example, Python's DNS resolver does not obey the timeout specified
        on the socket. Other factors that can affect total request time include
        high CPU load, high swap, the program running at a low priority level,
        or other behaviors.

        In addition, the read and total timeouts only measure the time between
        read operations on the socket connecting the client and the server,
        not the total amount of time for the request to return a complete
        response. For most requests, the timeout is raised because the server
        has not sent the first byte in the specified time. This is not always
        the case; if a server streams one byte every fifteen seconds, a timeout
        of 20 seconds will not trigger, even though the request will take
        several minutes to complete.

        If your goal is to cut off any request after a set amount of wall clock
        time, consider having a second "watcher" thread to cut off a slow
        request.

        Convert self into a url

        This function should more or less round-trip with :func:`.parse_url`. The
        returned url may not be exactly the same as the url inputted to
        :func:`.parse_url`, but it should be equivalent by the RFC (e.g., urls
        with a blank port will have : removed).

        Example: ::

            >>> U = parse_url('http://google.com/mail/')
            >>> U.url
            'http://google.com/mail/'
            >>> Url('http', 'username:password', 'host.com', 80,
            ... '/path', 'query', 'fragment').url

    Given a string and an iterable of delimiters, split on the first found
    delimiter. Return two split parts and the matched delimiter.

    If not found, then the first part is the full input string.

    Example::

        >>> split_first('foo/bar?baz', '?/=')
        ('foo', 'bar?baz', '/')
        >>> split_first('foo/bar?baz', '123')
        ('foo/bar?baz', '', None)

    Scales linearly with number of delims. Not ideal for large number of delims.

        These are the representations returned in response to an
        invocation of this method.
        a__iter__uResponseDefinition.__iter__uBind the response to a set of HTTP headers.

        A WADL response can have associated header parameters, but no
        other kind.

        This is very loosely based on the email module in the Python standard
        library.  However, that module doesn't really support directly embedding
        binary data in a form: various versions of Python have mangled line
        separators in different ways, and none of them get it quite right.
        Since we only need a tiny subset of MIME here, it's easier to implement
        it ourselves.

        :return: a tuple of two elements: the Content-Type of the message, and
            the entire encoded message as a byte string.

        :return: A 2-tuple (media_type, document).
        arepresentation_definitionsuTurn a representation ID into a RepresentationDefinition.TahrefuFind the URL containing the representation's 'real' definition.

        If a representation's structure is defined by reference, the
        <representation> tag's 'href' attribute will contain the URL
        to the <representation> that defines the structure.
        avalue_containeruInitialize with respect to a value container.

        :param value_container: Usually the resource whose representation
            has this parameter. If the resource is bound to a representation,
            you'll be able to find the value of this parameter in the
            representation. This may also be a server response whose headers
            define a value for this parameter.
        :tag: The ElementTree <param> tag for this parameter.
        uThe name of this parameter.uThe style of this parameter.uThe XSD type of this parameter.TafixeduThe value to which this parameter is fixed, if any.

        A fixed parameter must be present in invocations of a WADL
        method, and it must have a particular value. This is commonly
        used to designate one parameter as containing the name of the
        server-side operation to be invoked.
        TarequiredafalseLw1atrueuWhether or not a value for this parameter is required.aget_parameter_valueuThe value of this parameter in the bound representation/headers.

        :raise NoBoundRepresentationError: If this parameter's value
               container is not bound to a representation or a set of
               headers.
        TaoptionaOptionuReturn the set of acceptable values for this parameter.TalinkaLinkuGet the link to another resource.

        The link may be examined and, if its type is of a known WADL
        description, it may be followed.

        :return: A Link object, or None.
        alinkuThis parameter isn't a link to anything.afollowuFollow a link from this parameter to a new resource.

        This only works for parameters whose WADL definition includes a
        <link> tag that points to a known WADL description.

        :return: A Resource object for the resource at the other end
        of the link.
        aparameteruInitialize the option.

        :param parameter: A Parameter.
        :param link_tag: An ElementTree <option> tag.
        TavalueuInitialize the link.

        :param parameter: A Parameter.
        :param link_tag: An ElementTree <link> tag.
        acan_followaWADLErrorTuCannot follow a link when the target has no WADL description. Try using a general HTTP client instead.uFollow the link to another Resource.uCan this link be followed within wadllib?

        wadllib can follow a link if it points to a resource that has
        a WADL definition.
        aget_valueuTurn a resource type ID into a ResourceType.Taresource_typeTuParameter is a link, but not to a resource with a known WADL description.uFind the URL containing the definition .uInitialize with a <resource_type> tag.

        :param resource_type_tag: An ElementTree <resource_type> tag.
        areada_from_streamadoca_from_stringTaresourcesaresourcesTabasearesource_baseaResourceTypeuParse WADL and find the most important parts of the document.

        :param markup_url: The URL from which this document was obtained.
        :param markup: The WADL markup itself, or an open filehandle to it.
        aETaiterparseTastartustart-nsuend-nsustart-nsans_mapuend-nsapopastartarootaelemasetaElementTreeuTurns markup into a document.

        Just a wrapper around ElementTree which keeps track of namespaces.

        :param url: The URL (with anchor) of the desired part of the
        WADL document.
        :return: The XML ID corresponding to the anchor.
        apathuMore than one resource defined with path %samergeuLocate one of the resources described by this document.

        :param path: The path to the resource.
        uNavigate the resources exposed by a web service.

The wadllib library helps a web client navigate the resources
exposed by a web service. The service defines its resources in a
single WADL file. wadllib parses this file and gives access to the
resources defined inside. The client code can see the capabilities of
a given resource and make the corresponding HTTP requests.

If a request returns a representation of the resource, the client can
bind the string representation to the wadllib Resource object.

    parameter name that makes sense.
