.. function:: deque(iterable, maxlen[, flags])
Deques (double-ended queues) are a list-like container that support O(1)
appends and pops from either side of the deque. New deques are created
using the following arguments:
- *iterable* must be the empty tuple, and the new deque is created empty.
- *maxlen* must be specified and the deque will be bounded to this
maximum length. Once the deque is full, any new items added will
discard items from the opposite end.
- The optional *flags* can be 1 to check for overflow when adding items.
As well as supporting `bool` and `len`, deque objects have the following
methods:
.. method:: deque.append(x)
Add *x* to the right side of the deque.
Raises IndexError if overflow checking is enabled and there is no more room left.
.. method:: deque.popleft()
Remove and return an item from the left side of the deque.
Raises IndexError if no items are present.

Supported operators are:
Supported operators and special sequences are:
``'.'``
``.``
Match any character.
``'[...]'``
``[...]``
Match set of characters. Individual characters and ranges are supported,
including negated sets (e.g. ``[^a-c]``).
``'^'``
``^``
Match the start of the string.
``'$'``
``$``
Match the end of the string.
``'?'``
``?``
Match zero or one of the previous sub-pattern.
``'*'``
``*``
Match zero or more of the previous sub-pattern.
``'+'``
``+``
Match one or more of the previous sub-pattern.
``'??'``
``??``
Non-greedy version of ``?``, match zero or one, with the preference
for zero.
``'*?'``
``*?``
Non-greedy version of ``*``, match zero or more, with the preference
for the shortest match.
``'+?'``
``+?``
Non-greedy version of ``+``, match one or more, with the preference
for the shortest match.
``'|'``
``|``
Match either the left-hand side or the right-hand side sub-patterns of
this operator.
``'(...)'``
``(...)``
Grouping. Each group is capturing (a substring it captures can be accessed
with `match.group()` method).
**NOT SUPPORTED**: Counted repetitions (``{m,n}``), more advanced assertions
(``\b``, ``\B``), named groups (``(?P<name>...)``), non-capturing groups
(``(?:...)``), etc.
``\d``
Matches digit. Equivalent to ``[0-9]``.
``\D``
Matches non-digit. Equivalent to ``[^0-9]``.
``\s``
Matches whitespace. Equivalent to ``[ \t-\r]``.
``\S``
Matches non-whitespace. Equivalent to ``[^ \t-\r]``.
``\w``
Matches "word characters" (ASCII only). Equivalent to ``[A-Za-z0-9_]``.
``\W``
Matches non "word characters" (ASCII only). Equivalent to ``[^A-Za-z0-9_]``.
``\``
Escape character. Any other character following the backslash, except
for those listed above, is taken literally. For example, ``\*`` is
equivalent to literal ``*`` (not treated as the ``*`` operator).
Note that ``\r``, ``\n``, etc. are not handled specially, and will be
equivalent to literal letters ``r``, ``n``, etc. Due to this, it's
not recommended to use raw Python strings (``r""``) for regular
expressions. For example, ``r"\r\n"`` when used as the regular
expression is equivalent to ``"rn"``. To match CR character followed
by LF, use ``"\r\n"``.
**NOT SUPPORTED**:
* counted repetitions (``{m,n}``)
* named groups (``(?P<name>...)``)
* non-capturing groups (``(?:...)``)
* more advanced assertions (``\b``, ``\B``)
* special character escapes like ``\r``, ``\n`` - use Python's own escaping
instead
* etc.
Example::
import ure
# As ure doesn't support escapes itself, use of r"" strings is not
# recommended.

Limitations
-----------
Accessing non-scalar fields leads to allocation of intermediate objects
1. Accessing non-scalar fields leads to allocation of intermediate objects
to represent them. This means that special care should be taken to
layout a structure which needs to be accessed when memory allocation
is disabled (e.g. from an interrupt). The recommendations are:
* Avoid nested structures. For example, instead of
* Avoid accessing nested structures. For example, instead of
``mcu_registers.peripheral_a.register1``, define separate layout
descriptors for each peripheral, to be accessed as
``peripheral_a.register1``.
* Avoid other non-scalar data, like array. For example, instead of
``peripheral_a.register[0]`` use ``peripheral_a.register0``.
``peripheral_a.register1``. Or just cache a particular peripheral:
``peripheral_a = mcu_registers.peripheral_a``. If a register
consists of multiple bitfields, you would need to cache references
to a particular register: ``reg_a = mcu_registers.peripheral_a.reg_a``.
* Avoid other non-scalar data, like arrays. For example, instead of
``peripheral_a.register[0]`` use ``peripheral_a.register0``. Again,
an alternative is to cache intermediate values, e.g.
``register0 = peripheral_a.register[0]``.
Note that these recommendations will lead to decreased readability
and conciseness of layouts, so they should be used only if the need
to access structure fields without allocation is anticipated (it's
even possible to define 2 parallel layouts - one for normal usage,
and a restricted one to use when memory allocation is prohibited).
2. Range of offsets supported by the ``uctypes`` module is limited.
The exact range supported is considered an implementation detail,
and the general suggestion is to split structure definitions to
cover from a few kilobytes to a few dozen of kilobytes maximum.
In most cases, this is a natural situation anyway, e.g. it doesn't make
sense to define all registers of an MCU (spread over 32-bit address
space) in one structure, but rather a peripheral block by peripheral
block. In some extreme cases, you may need to split a structure in
several parts artificially (e.g. if accessing native data structure
with multi-megabyte array in the middle, though that would be a very
synthetic case).

:mod:`usocket` -- socket module
*******************************
.. include:: ../templates/unsupported_in_circuitpython.inc
.. module:: usocket
:synopsis: socket module
|see_cpython_module| :mod:`cpython:socket`.
This module provides access to the BSD socket interface.
.. admonition:: Difference to CPython
:class: attention
For efficiency and consistency, socket objects in MicroPython implement a ``stream``
(file-like) interface directly. In CPython, you need to convert a socket to
a file-like object using `makefile()` method. This method is still supported
by MicroPython (but is a no-op), so where compatibility with CPython matters,
be sure to use it.
Socket address format(s)
------------------------
The native socket address format of the ``usocket`` module is an opaque data type
returned by `getaddrinfo` function, which must be used to resolve textual address
(including numeric addresses)::
sockaddr = usocket.getaddrinfo('www.micropython.org', 80)[0][-1]
# You must use getaddrinfo() even for numeric addresses
sockaddr = usocket.getaddrinfo('127.0.0.1', 80)[0][-1]
# Now you can use that address
sock.connect(addr)
Using `getaddrinfo` is the most efficient (both in terms of memory and processing
power) and portable way to work with addresses.
However, ``socket`` module (note the difference with native MicroPython
``usocket`` module described here) provides CPython-compatible way to specify
addresses using tuples, as described below.
Summing up:
* Always use `getaddrinfo` when writing portable applications.
* Tuple addresses described below can be used as a shortcut for
quick hacks and interactive use, if your port supports them.
Tuple address format for ``socket`` module:
* IPv4: *(ipv4_address, port)*, where *ipv4_address* is a string with
dot-notation numeric IPv4 address, e.g. ``"8.8.8.8"``, and *port* is and
integer port number in the range 1-65535. Note the domain names are not
accepted as *ipv4_address*, they should be resolved first using
`usocket.getaddrinfo()`.
* IPv6: *(ipv6_address, port, flowinfo, scopeid)*, where *ipv6_address*
is a string with colon-notation numeric IPv6 address, e.g. ``"2001:db8::1"``,
and *port* is an integer port number in the range 1-65535. *flowinfo*
must be 0. *scopeid* is the interface scope identifier for link-local
addresses. Note the domain names are not accepted as *ipv6_address*,
they should be resolved first using `usocket.getaddrinfo()`.
Functions
---------
.. function:: socket(af=AF_INET, type=SOCK_STREAM, proto=IPPROTO_TCP)
Create a new socket using the given address family, socket type and
protocol number. Note that specifying *proto* in most cases is not
required (and not recommended, as some MicroPython ports may omit
``IPPROTO_*`` constants). Instead, *type* argument will select needed
protocol automatically::
# Create STREAM TCP socket
socket(AF_INET, SOCK_STREAM)
# Create DGRAM UDP socket
socket(AF_INET, SOCK_DGRAM)
.. function:: getaddrinfo(host, port)
Translate the host/port argument into a sequence of 5-tuples that contain all the
necessary arguments for creating a socket connected to that service. The list of
5-tuples has following structure::
(family, type, proto, canonname, sockaddr)
The following example shows how to connect to a given url::
s = usocket.socket()
s.connect(usocket.getaddrinfo('www.micropython.org', 80)[0][-1])
.. admonition:: Difference to CPython
:class: attention
CPython raises a ``socket.gaierror`` exception (`OSError` subclass) in case
of error in this function. MicroPython doesn't have ``socket.gaierror``
and raises OSError directly. Note that error numbers of `getaddrinfo()`
form a separate namespace and may not match error numbers from
:py:mod:`uerrno` module. To distinguish `getaddrinfo()` errors, they are
represented by negative numbers, whereas standard system errors are
positive numbers (error numbers are accessible using ``e.args[0]`` property
from an exception object). The use of negative values is a provisional
detail which may change in the future.
.. function:: inet_ntop(af, bin_addr)
Convert a binary network address *bin_addr* of the given address family *af*
to a textual representation::
>>> usocket.inet_ntop(usocket.AF_INET, b"\x7f\0\0\1")
'127.0.0.1'
.. function:: inet_pton(af, txt_addr)
Convert a textual network address *txt_addr* of the given address family *af*
to a binary representation::

Note that you don't need to specify these in a call to `usocket.socket()`,
because `SOCK_STREAM` socket type automatically selects `IPPROTO_TCP`, and
`SOCK_DGRAM` - `IPPROTO_UDP`. Thus, the only real use of these constants
is as an argument to `usocket.socket.setsockopt()`.

class socket
============
Methods
-------
.. method:: socket.close()
Mark the socket closed and release all resources. Once that happens, all future operations
on the socket object will fail. The remote end will receive EOF indication if
supported by protocol.
Sockets are automatically closed when they are garbage-collected, but it is recommended
to `close()` them explicitly as soon you finished working with them.
.. method:: socket.bind(address)
Bind the socket to *address*. The socket must not already be bound.
.. method:: socket.listen([backlog])
Enable a server to accept connections. If *backlog* is specified, it must be at least 0
(if it's lower, it will be set to 0); and specifies the number of unaccepted connections
that the system will allow before refusing new connections. If not specified, a default
reasonable value is chosen.
.. method:: socket.accept()
Accept a connection. The socket must be bound to an address and listening for connections.
The return value is a pair (conn, address) where conn is a new socket object usable to send
and receive data on the connection, and address is the address bound to the socket on the
other end of the connection.
.. method:: socket.connect(address)
Connect to a remote socket at *address*.
.. method:: socket.send(bytes)
Send data to the socket. The socket must be connected to a remote socket.
Returns number of bytes sent, which may be smaller than the length of data
("short write").
.. method:: socket.sendall(bytes)
Send all data to the socket. The socket must be connected to a remote socket.
Unlike `send()`, this method will try to send all of data, by sending data
chunk by chunk consecutively.
The behavior of this method on non-blocking sockets is undefined. Due to this,
on MicroPython, it's recommended to use `write()` method instead, which
has the same "no short writes" policy for blocking sockets, and will return
number of bytes sent on non-blocking sockets.
.. method:: socket.recv(bufsize)
Receive data from the socket. The return value is a bytes object representing the data
received. The maximum amount of data to be received at once is specified by bufsize.
.. method:: socket.sendto(bytes, address)
Send data to the socket. The socket should not be connected to a remote socket, since the
destination socket is specified by *address*.
.. method:: socket.recvfrom(bufsize)
Receive data from the socket. The return value is a pair *(bytes, address)* where *bytes* is a
bytes object representing the data received and *address* is the address of the socket sending
the data.
.. method:: socket.setsockopt(level, optname, value)
Set the value of the given socket option. The needed symbolic constants are defined in the
socket module (SO_* etc.). The *value* can be an integer or a bytes-like object representing
a buffer.
.. method:: socket.settimeout(value)
**Note**: Not every port supports this method, see below.
Set a timeout on blocking socket operations. The value argument can be a nonnegative floating
point number expressing seconds, or None. If a non-zero value is given, subsequent socket operations
will raise an `OSError` exception if the timeout period value has elapsed before the operation has
completed. If zero is given, the socket is put in non-blocking mode. If None is given, the socket
is put in blocking mode.
Not every ``MicroPython port`` supports this method. A more portable and
generic solution is to use `uselect.poll` object. This allows to wait on
multiple objects at the same time (and not just on sockets, but on generic
``stream`` objects which support polling). Example::
# Instead of:
s.settimeout(1.0) # time in seconds
s.read(10) # may timeout
# Use:
poller = uselect.poll()
poller.register(s, uselect.POLLIN)
res = poller.poll(1000) # time in milliseconds
if not res:
# s is still not ready for input, i.e. operation timed out
.. admonition:: Difference to CPython
:class: attention
CPython raises a ``socket.timeout`` exception in case of timeout,
which is an `OSError` subclass. MicroPython raises an OSError directly
instead. If you use ``except OSError:`` to catch the exception,
your code will work both in MicroPython and CPython.
.. method:: socket.setblocking(flag)
Set blocking or non-blocking mode of the socket: if flag is false, the socket is set to non-blocking,
else to blocking mode.
This method is a shorthand for certain `settimeout()` calls:
* ``sock.setblocking(True)`` is equivalent to ``sock.settimeout(None)``
* ``sock.setblocking(False)`` is equivalent to ``sock.settimeout(0)``
.. method:: socket.makefile(mode='rb', buffering=0)
Return a file object associated with the socket. The exact returned type depends on the arguments
given to makefile(). The support is limited to binary modes only ('rb', 'wb', and 'rwb').
CPython's arguments: *encoding*, *errors* and *newline* are not supported.
.. admonition:: Difference to CPython
:class: attention
As MicroPython doesn't support buffered streams, values of *buffering*
parameter is ignored and treated as if it was 0 (unbuffered).
.. admonition:: Difference to CPython
:class: attention
Closing the file object returned by makefile() WILL close the
original socket as well.
.. method:: socket.read([size])
Read up to size bytes from the socket. Return a bytes object. If *size* is not given, it
reads all data available from the socket until EOF; as such the method will not return until
the socket is closed. This function tries to read as much data as
requested (no "short reads"). This may be not possible with
non-blocking socket though, and then less data will be returned.
.. method:: socket.readinto(buf[, nbytes])
Read bytes into the *buf*. If *nbytes* is specified then read at most
that many bytes. Otherwise, read at most *len(buf)* bytes. Just as
`read()`, this method follows "no short reads" policy.
Return value: number of bytes read and stored into *buf*.
.. method:: socket.readline()
Read a line, ending in a newline character.
Return value: the line read.
.. method:: socket.write(buf)
Write the buffer of bytes to the socket. This function will try to
write all data to a socket (no "short writes"). This may be not possible
with a non-blocking socket though, and returned value will be less than
the length of *buf*.
Return value: number of bytes written.
.. exception:: usocket.error
MicroPython does NOT have this exception.
.. admonition:: Difference to CPython
:class: attention
CPython used to have a ``socket.error`` exception which is now deprecated,
and is an alias of `OSError`. In MicroPython, use `OSError` directly.

:mod:`ussl` -- SSL/TLS module
=============================
.. include:: ../templates/unsupported_in_circuitpython.inc
.. module:: ussl
:synopsis: TLS/SSL wrapper for socket objects
|see_cpython_module| :mod:`cpython:ssl`.
This module provides access to Transport Layer Security (previously and
widely known as “Secure Sockets Layer”) encryption and peer authentication
facilities for network sockets, both client-side and server-side.
Functions
---------
.. function:: ussl.wrap_socket(sock, server_side=False, keyfile=None, certfile=None, cert_reqs=CERT_NONE, ca_certs=None)
Takes a ``stream`` *sock* (usually usocket.socket instance of ``SOCK_STREAM`` type),
and returns an instance of ssl.SSLSocket, which wraps the underlying stream in
an SSL context. Returned object has the usual ``stream`` interface methods like
``read()``, ``write()``, etc. In MicroPython, the returned object does not expose
socket interface and methods like ``recv()``, ``send()``. In particular, a
server-side SSL socket should be created from a normal socket returned from
:meth:`~usocket.socket.accept()` on a non-SSL listening server socket.
Depending on the underlying module implementation in a particular
``MicroPython port``, some or all keyword arguments above may be not supported.
.. warning::
Some implementations of ``ussl`` module do NOT validate server certificates,
which makes an SSL connection established prone to man-in-the-middle attacks.
Exceptions
----------
.. data:: ssl.SSLError
This exception does NOT exist. Instead its base class, OSError, is used.
Constants
---------
.. data:: ussl.CERT_NONE
ussl.CERT_OPTIONAL
ussl.CERT_REQUIRED
Supported values for *cert_reqs* parameter.

* @defgroup WIZnet_socket_APIs 1. WIZnet socket APIs
* @brief WIZnet socket APIs are based on Berkeley socket APIs, thus it has much similar name and interface.
* But there is a little bit of difference.
* @details
* <b> Comparison between WIZnet and Berkeley SOCKET APIs </b>
* <table>
* <tr> <td><b>API</b></td> <td><b>WIZnet</b></td> <td><b>Berkeley</b></td> </tr>
* <tr> <td>socket()</td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>bind()</b></td> <td>X</td> <td>O</td> </tr>
* <tr> <td><b>listen()</b></td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>connect()</b></td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>accept()</b></td> <td>X</td> <td>O</td> </tr>
* <tr> <td><b>recv()</b></td> <td>O</td> <td>O</td> </tr>

* <tr> <td><b>recvfrom()</b></td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>sendto()</b></td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>closesocket()</b></td> <td>O<br>close() & disconnect()</td> <td>O</td> </tr>
* </table>
* There are @b bind() and @b accept() functions in @b Berkeley SOCKET API but,
* not in @b WIZnet SOCKET API. Because socket() of WIZnet is not only creating a SOCKET but also binding a local port number,
* and listen() of WIZnet is not only listening to connection request from client but also accepting the connection request. \n
* When you program "TCP SERVER" with Berkeley SOCKET API, you can use only one listen port.
* When the listen SOCKET accepts a connection request from a client, it keeps listening.
* After accepting the connection request, a new SOCKET is created and the new SOCKET is used in communication with the client. \n
* Following figure shows network flow diagram by Berkeley SOCKET API.
* @image html Berkeley_SOCKET.jpg "<Berkeley SOCKET API>"
* But, When you program "TCP SERVER" with WIZnet SOCKET API, you can use as many as 8 listen SOCKET with same port number. \n
* Because there's no accept() in WIZnet SOCKET APIs, when the listen SOCKET accepts a connection request from a client,
* it is changed in order to communicate with the client.
* And the changed SOCKET is not listening any more and is dedicated for communicating with the client. \n
* If there're many listen SOCKET with same listen port number and a client requests a connection,
* the SOCKET which has the smallest SOCKET number accepts the request and is changed as communication SOCKET. \n
* Following figure shows network flow diagram by WIZnet SOCKET API.
