+
+ Usage::
+
+ P = ParamSpec('P')
+
+ Parameter specification variables exist primarily for the benefit of static
+ type checkers. They are used to forward the parameter types of one
+ callable to another callable, a pattern commonly found in higher order
+ functions and decorators. They are only valid when used in ``Concatenate``,
+ or s the first argument to ``Callable``. In Python 3.10 and higher,
+ they are also supported in user-defined Generics at runtime.
+ See class Generic for more information on generic types. An
+ example for annotating a decorator::
+
+ T = TypeVar('T')
+ P = ParamSpec('P')
+
+ def add_logging(f: Callable[P, T]) -> Callable[P, T]:
+ '''A type-safe decorator to add logging to a function.'''
+ def inner(*args: P.args, **kwargs: P.kwargs) -> T:
+ logging.info(f'{f.__name__} was called')
+ return f(*args, **kwargs)
+ return inner
+
+ @add_logging
+ def add_two(x: float, y: float) -> float:
+ '''Add two numbers together.'''
+ return x + y
+
+ Parameter specification variables defined with covariant=True or
+ contravariant=True can be used to declare covariant or contravariant
+ generic types. These keyword arguments are valid, but their actual semantics
+ are yet to be decided. See PEP 612 for details.
+
+ Parameter specification variables can be introspected. e.g.:
+
+ P.__name__ == 'T'
+ P.__bound__ == None
+ P.__covariant__ == False
+ P.__contravariant__ == False
+
+ Note that only parameter specification variables defined in global scope can

+
+1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is

+ limitations.
+2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets.
+ Sockets also have `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

+TLS with SNI_-support for Python 2. Follow these instructions if you would
+like to verify TLS 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:
+
+.. code-block:: bash
+
+ $ python -m 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:
+
+.. 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`_).

+SecureTranport support for urllib3 via ctypes.
+
+This makes platform-native TLS available to urllib3 users on macOS without the
+use of a compiler. This is an important feature because the Python Package
+Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL
+that ships with macOS is not capable of doing TLSv1.2. The only way to resolve
+this is to give macOS users an alternative solution to the problem, and that
+solution is to use SecureTransport.
+
+We use ctypes here because this solution must not require a compiler. That's
+because pip is not allowed to require a compiler either.
+
+This is not intended to be a seriously long-term solution to this problem.
+The hope is that PEP 543 will eventually solve this issue for us, at which
+point we can retire this contrib module. But in the short term, we need to
+solve the impending tire fire that is Python on Mac without this kind of
+contrib module. So...here we are.
+
+To use this module, simply import and inject it::
+
+ import pip._vendor.urllib3.contrib.securetransport as securetransport
+ securetransport.inject_into_urllib3()
+
+Happy TLSing!
+

+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:
+
+.. code-block:: python
+
+ proxy_url="socks4a://@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:
+
+.. code-block:: python
+
+ proxy_url="socks5h://:@proxy-host"

+
+ 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.
+
+ 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

+
+ Set to ``0`` to fail on the first retry of this type.
+
+ :param int other:
+ How many times to retry on other errors.
+
+ Other errors are errors that are not connect, read, redirect or status errors.
+ These errors might be raised after the request was sent to the server, so the
+ request might have side-effects.
+
+ Set to ``0`` to fail on the first retry of this type.
+
+ If ``total`` is not set, it's a good idea to set this to 0 to account
+ for unexpected edge cases and avoid infinite retry loops.
+
+ :param iterable allowed_methods:
+ 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_ALLOWED_METHODS`.

+
+ .. warning::
+
+ Previously this parameter was named ``method_whitelist``, that
+ usage is deprecated in v1.26.0 and will be removed in v2.0.
+
+ :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 ``allowed_methods``
+ 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.DEFAULT_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`.
