This can be done in a ``sitecustomize`` +module, or at any other time before your application begins using ``urllib3``, +like this: + +.. code-block:: python + + try: + import pip._vendor.urllib3.contrib.pyopenssl as pyopenssl + 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`_). + +.. _sni: https://en.wikipedia.org/wiki/Server_Name_Indication +.. _crime attack: https://en.wikipedia.org/wiki/CRIME_(security_exploit) +.. _pyopenssl: https://www.pyopenssl.org +.. _cryptography: https://cryptography.io +.. _idna: https://github.com/kjd/idna +""" +from __future__ import absolute_import + +import OpenSSL.crypto +import OpenSSL.SSL +from cryptography import x509 +from cryptography.hazmat.backends.openssl import backend as openssl_backend + +try: + from cryptography.x509 import UnsupportedExtension +except ImportError: + # UnsupportedExtension is gone in cryptography >= 2.1.0 + class UnsupportedExtension(Exception): + pass + + +from io import BytesIO +from socket import error as SocketError +from socket import timeout + +try: # Platform-specific: Python 2 + from socket import _fileobject +except ImportError: # Platform-specific: Python 3 + _fileobject = None + from ..packages.backports.makefile import backport_makefile + +import logging +import ssl +import sys +import warnings + +from .. import util +from ..packages import six +from ..util.ssl_ import PROTOCOL_TLS_CLIENT + +warnings.warn( + "'urllib3.contrib.pyopenssl' module is deprecated and will be removed " + "in a future release of urllib3 2.x.

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 + + 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. +""" + +import datetime +import numbers +import re +import sys +import os +import textwrap + +from tornado.escape import _unicode, native_str +from tornado.log import define_logging_options +from tornado.util import basestring_type, exec_in + +from typing import ( + Any, + Iterator, + Iterable, + Tuple, + Set, + Dict, + Callable, + List, + TextIO, + Optional, +) + + +class Error(Exception): + """Exception raised by errors in the options module.""" + + pass + + +class OptionParser: + """A collection of options, a dictionary with object-like access. + + Normally accessed via static functions in the `tornado.options` module, + which reference a global instance. + """ + + def __init__(self) -> None: + # we have to use self.__dict__ because we override setattr. + self.__dict__["_options"] = {} + self.__dict__["_parse_callbacks"] = [] + self.define( + "help", + type=bool, + help="show this help information", + callback=self._help_callback, + ) + + def _normalize_name(self, name: str) -> str: + return name.replace("_", "-") + + def __getattr__(self, name: str) -> Any: + name = self._normalize_name(name) + if isinstance(self._options.get(name), _Option): + return self._options[name].value() + raise AttributeError("Unrecognized option %r" % name) + + def __setattr__(self, name: str, value: Any) -> None: + name = self._normalize_name(name) + if isinstance(self._options.get(name), _Option): + return self._options[name].set(value) + raise AttributeError("Unrecognized option %r" % name) + + def __iter__(self) -> Iterator: + return (opt.name for opt in self._options.values()) + + def __contains__(self, name: str) -> bool: + name = self._normalize_name(name) + return name in self._options + + def __getitem__(self, name: str) -> Any: + return self.__getattr__(name) + + def __setitem__(self, name: str, value: Any) -> None: + return self.__setattr__(name, value) + + def items(self) -> Iterable[Tuple[str, Any]]: + """An iterable of (name, value) pairs. + + .. versionadded:: 3.1 + """ + return [(opt.name, opt.value()) for name, opt in self._options.items()] + + def groups(self) -> Set[str]: + """The set of option-groups created by ``define``. + + .. versionadded:: 3.1 + """ + return {opt.group_name for opt in self._options.values()} + + def group_dict(self, group: str) -> Dict[str, Any]: + """The names and values of options in a group. + + Useful for copying options into Application settings:: + + from tornado.options import define, parse_command_line, options + + define('template_path', group='application') + define('static_path', group='application') + + parse_command_line() + + application = Application( + handlers, **options.group_dict('application')) + + .. versionadded:: 3.1 + """ + return { + opt.name: opt.value() + for name, opt in self._options.items() + if not group or group == opt.group_name + } + + def as_dict(self) -> Dict[str, Any]: + """The names and values of all options. + + .. versionadded:: 3.1 + """ + return {opt.name: opt.value() for name, opt in self._options.items()} + + def define( + self, + name: str, + default: Any = None, + type: Optional[type] = None, + help: Optional[str] = None, + metavar: Optional[str] = None, + multiple: bool = False, + group: Optional[str] = None, + callback: Optional[Callable[[Any], None]] = None, + ) -> None: + """Defines a new command line option. + + ``type`` can be any of `str`, `int`, `float`, `bool`, + `~datetime.datetime`, or `~datetime.timedelta`.

+"""``tornado.web`` provides a simple web framework with asynchronous
+features that allow it to scale to large numbers of open connections,
+making it ideal for `long polling
+`_.
+
+Here is a simple "Hello, world" example app:
+
+.. testcode::
+
+    import asyncio
+    import tornado
+
+    class MainHandler(tornado.web.RequestHandler):
+        def get(self):
+            self.write("Hello, world")
+
+    async def main():
+        application = tornado.web.Application([
+            (r"/", MainHandler),
+        ])
+        application.listen(8888)
+        await asyncio.Event().wait()
+
+    if __name__ == "__main__":
+        asyncio.run(main())
+
+See the :doc:`guide` for additional information.
+
+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.

+            (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 ` 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.

+    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`.

+    """Subclass this class to create a basic WebSocket handler.
+
+    Override `on_message` to handle incoming messages, and use
+    `write_message` to send messages to the client. You can also
+    override `open` and `on_close` to handle opened and closed
+    connections.
+
+    Custom upgrade response headers can be sent by overriding
+    `~tornado.web.RequestHandler.set_default_headers` or
+    `~tornado.web.RequestHandler.prepare`.
+
+    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")
+
+    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``.
+    Both settings are in seconds; floating point values are allowed.
+    The default timeout is equal to the interval.
+
+    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``.

+    .. warning::
+
+       WSGI is a *synchronous* interface, while Tornado's concurrency model
+       is based on single-threaded *asynchronous* execution.  Many of Tornado's
+       distinguishing features are not available in WSGI mode, including efficient
+       long-polling and websockets. The primary purpose of `WSGIContainer` is
+       to support both WSGI applications and native Tornado ``RequestHandlers`` in
+       a single process. WSGI-only applications are likely to be better off
+       with a dedicated WSGI server such as ``gunicorn`` or ``uwsgi``.
+
+    Wrap a WSGI application in a `WSGIContainer` to make it implement the Tornado
+    `.HTTPServer` ``request_callback`` interface.  The `WSGIContainer` object can
+    then be passed to classes from the `tornado.routing` module,
+    `tornado.web.FallbackHandler`, or to `.HTTPServer` directly.
+
+    This class is intended to let other frameworks (Django, Flask, etc)
+    run on the Tornado HTTP server and I/O loop.
+
+    Realistic usage will be more complicated, but the simplest possible example uses a
+    hand-written WSGI application with `.HTTPServer`::
+
+        def simple_app(environ, start_response):
+            status = "200 OK"

+
+    The recommended pattern is to use the `tornado.routing` module to set up routing
+    rules between your WSGI application and, typically, a `tornado.web.Application`.
+    Alternatively, `tornado.web.Application` can be used as the top-level router
+    and `tornado.web.FallbackHandler` can embed a `WSGIContainer` within it.
+
+    If the ``executor`` argument is provided, the WSGI application will be executed
+    on that executor. This must be an instance of `concurrent.futures.Executor`,
+    typically a ``ThreadPoolExecutor`` (``ProcessPoolExecutor`` is not supported).
+    If no ``executor`` is given, the application will run on the event loop thread in
+    Tornado 6.3; this will change to use an internal thread pool by default in
+    Tornado 7.0.
+
+    .. warning::
+       By default, the WSGI application is executed on the event loop's thread. This
+       limits the server to one request at a time (per process), making it less scalable
+       than most other WSGI servers. It is therefore highly recommended that you pass
+       a ``ThreadPoolExecutor`` when constructing the `WSGIContainer`, after verifying
+       that your application is thread-safe. The default will change to use a
+       ``ThreadPoolExecutor`` in Tornado 7.0.
+
+    .. versionadded:: 6.3
+       The ``executor`` parameter.
+
+    .. deprecated:: 6.3
+       The default behavior of running the WSGI application on the event loop thread
+       is deprecated and will change in Tornado 7.0 to use a thread pool by default.
