        Highlights
        ==========
        
        - Re-use the same socket connection for multiple requests
          (``HTTPConnectionPool`` and ``HTTPSConnectionPool``)
          (with optional client-side certificate verification).
        - File posting (``encode_multipart_formdata``).
        - Built-in redirection and retries (optional).
        - Supports gzip and deflate decoding.
        - Thread-safe and sanity-safe.
        - Works with AppEngine, gevent, and eventlib.
        - Tested on Python 2.6+, Python 3.2+, and PyPy, with 100% unit test coverage.
        - Small and easy to understand codebase perfect for extending and building upon.
          For a more comprehensive solution, have a look at
          `Requests <http://python-requests.org/>`_ which is also powered by ``urllib3``.
        
        
        You might already be using urllib3!
        ===================================
        
        ``urllib3`` powers `many great Python libraries
        <https://sourcegraph.com/search?q=package+urllib3>`_, including ``pip`` and
        ``requests``.
        
        
        What's wrong with urllib and urllib2?
        =====================================
        
        There are two critical features missing from the Python standard library:
        Connection re-using/pooling and file posting. It's not terribly hard to
        implement these yourself, but it's much easier to use a module that already
        did the work for you.
        
        The Python standard libraries ``urllib`` and ``urllib2`` have little to do
        with each other. They were designed to be independent and standalone, each
        solving a different scope of problems, and ``urllib3`` follows in a similar
        vein.
        
        
        Why do I want to reuse connections?
        ===================================
        
        Performance. When you normally do a urllib call, a separate socket
        connection is created with each request. By reusing existing sockets
        (supported since HTTP 1.1), the requests will take up less resources on the
        server's end, and also provide a faster response time at the client's end.
        With some simple benchmarks (see `test/benchmark.py
        <https://github.com/shazow/urllib3/blob/master/test/benchmark.py>`_
        ), downloading 15 URLs from google.com is about twice as fast when using
        HTTPConnectionPool (which uses 1 connection) than using plain urllib (which
        uses 15 connections).
        
        This library is perfect for:
        
        - Talking to an API
        - Crawling a website
        - Any situation where being able to post files, handle redirection, and
          retrying is useful. It's relatively lightweight, so it can be used for
          anything!
        
        
        Examples
        ========
        
        Go to `urllib3.readthedocs.org <http://urllib3.readthedocs.org>`_
        for more nice syntax-highlighted examples.
        
        But, long story short::
        
          import urllib3
        
          http = urllib3.PoolManager()
        
          r = http.request('GET', 'http://google.com/')
        
          print r.status, r.data
        
        The ``PoolManager`` will take care of reusing connections for you whenever
        you request the same host. For more fine-grained control of your connection
        pools, you should look at `ConnectionPool
        <http://urllib3.readthedocs.org/#connectionpool>`_.
        
        
        Run the tests
        =============
        
        We use some external dependencies, multiple interpreters and code coverage
        analysis while running test suite. Our ``Makefile`` handles much of this for
        you as long as you're running it `inside of a virtualenv
        <http://docs.python-guide.org/en/latest/dev/virtualenvs/>`_::
        
          $ make test
          [... magically installs dependencies and runs tests on your virtualenv]
          Ran 182 tests in 1.633s
        
          OK (SKIP=6)
        
        Note that code coverage less than 100% is regarded as a failing run. Some
        platform-specific tests are skipped unless run in that platform.  To make sure
        the code works in all of urllib3's supported platforms, you can run our ``tox``
        suite::
        
          $ make test-all
          [... tox creates a virtualenv for every platform and runs tests inside of each]

          py33: commands succeeded

        1.9 (2014-07-04)
        ++++++++++++++++
        
        * Shuffled around development-related files. If you're maintaining a distro
          package of urllib3, you may need to tweak things. (Issue #415)
        
        * Unverified HTTPS requests will trigger a warning on the first request. See
          our new `security documentation
          <https://urllib3.readthedocs.org/en/latest/security.html>`_ for details.
          (Issue #426)

          (Issue #326)
        
        * All raised exceptions should now wrapped in a
          ``urllib3.exceptions.HTTPException``-extending exception. (Issue #326)
        
        * All errors during a retry-enabled request should be wrapped in
          ``urllib3.exceptions.MaxRetryError``, including timeout-related exceptions
          which were previously exempt. Underlying error is accessible from the
          ``.reason`` propery. (Issue #326)
        
        * ``urllib3.exceptions.ConnectionError`` renamed to
          ``urllib3.exceptions.ProtocolError``. (Issue #326)
        
        * Errors during response read (such as IncompleteRead) are now wrapped in
          ``urllib3.exceptions.ProtocolError``. (Issue #418)
        
        * Requesting an empty host will raise ``urllib3.exceptions.LocationValueError``.
          (Issue #417)
        
        * Catch read timeouts over SSL connections as
          ``urllib3.exceptions.ReadTimeoutError``. (Issue #419)

        1.8.3 (2014-06-23)
        ++++++++++++++++++
        
        * Fix TLS verification when using a proxy in Python 3.4.1. (Issue #385)
        
        * Add ``disable_cache`` option to ``urllib3.util.make_headers``. (Issue #393)
        
        * Wrap ``socket.timeout`` exception with
          ``urllib3.exceptions.ReadTimeoutError``. (Issue #399)
        
        * Fixed proxy-related bug where connections were being reused incorrectly.
          (Issues #366, #369)
        
        * Added ``socket_options`` keyword parameter which allows to define
          ``setsockopt`` configuration of new sockets. (Issue #397)
        
        * Removed ``HTTPConnection.tcp_nodelay`` in favor of
          ``HTTPConnection.default_socket_options``. (Issue #397)
        
        * Fixed ``TypeError`` bug in Python 2.6.4. (Issue #411)
        
        
        1.8.2 (2014-04-17)
        ++++++++++++++++++

        1.8.1 (2014-04-17)
        ++++++++++++++++++
        
        * Fix AppEngine bug of HTTPS requests going out as HTTP. (Issue #356)
        
        * Don't install ``dummyserver`` into ``site-packages`` as it's only needed
          for the test suite. (Issue #362)
        
        * Added support for specifying ``source_address``. (Issue #352)
        
        
        1.8 (2014-03-04)
        ++++++++++++++++
        
        * Improved url parsing in ``urllib3.util.parse_url`` (properly parse '@' in
          username, and blank ports like 'hostname:').
        
        * New ``urllib3.connection`` module which contains all the HTTPConnection
          objects.
        
        * Several ``urllib3.util.Timeout``-related fixes. Also changed constructor
          signature to a more sensible order. [Backwards incompatible]
          (Issues #252, #262, #263)
        
        * Use ``backports.ssl_match_hostname`` if it's installed. (Issue #274)
        
        * Added ``.tell()`` method to ``urllib3.response.HTTPResponse`` which
          returns the number of bytes read so far. (Issue #277)
        
        * Support for platforms without threading. (Issue #289)
        
        * Expand default-port comparison in ``HTTPConnectionPool.is_same_host``
          to allow a pool with no specified port to be considered equal to to an
          HTTP/HTTPS url with port 80/443 explicitly provided. (Issue #305)
        
        * Improved default SSL/TLS settings to avoid vulnerabilities.
          (Issue #309)
        
        * Fixed ``urllib3.poolmanager.ProxyManager`` not retrying on connect errors.
          (Issue #310)
        
        * Disable Nagle's Algorithm on the socket for non-proxies. A subset of requests
          will send the entire HTTP request ~200 milliseconds faster; however, some of
          the resulting TCP packets will be smaller. (Issue #254)
        
        * Increased maximum number of SubjectAltNames in ``urllib3.contrib.pyopenssl``
          from the default 64 to 1024 in a single certificate. (Issue #318)
        
        * Headers are now passed and stored as a custom
          ``urllib3.collections_.HTTPHeaderDict`` object rather than a plain ``dict``.
          (Issue #329, #333)
        
        * Headers no longer lose their case on Python 3. (Issue #236)
        
        * ``urllib3.contrib.pyopenssl`` now uses the operating system's default CA
          certificates on inject. (Issue #332)
        
        * Requests with ``retries=False`` will immediately raise any exceptions without
          wrapping them in ``MaxRetryError``. (Issue #348)
        
        * Fixed open socket leak with SSL-related failures. (Issue #344, #348)
        
        
        1.7.1 (2013-09-25)
        ++++++++++++++++++
        
        * Added granular timeout support with new ``urllib3.util.Timeout`` class.
          (Issue #231)
        
        * Fixed Python 3.4 support. (Issue #238)
        
        
        1.7 (2013-08-14)
        ++++++++++++++++
        
        * More exceptions are now pickle-able, with tests. (Issue #174)
        
        * Fixed redirecting with relative URLs in Location header. (Issue #178)
        
        * Support for relative urls in ``Location: ...`` header. (Issue #179)
        
        * ``urllib3.response.HTTPResponse`` now inherits from ``io.IOBase`` for bonus
          file-like functionality. (Issue #187)
        
        * Passing ``assert_hostname=False`` when creating a HTTPSConnectionPool will
          skip hostname verification for SSL connections. (Issue #194)
        
        * New method ``urllib3.response.HTTPResponse.stream(...)`` which acts as a
          generator wrapped around ``.read(...)``. (Issue #198)
        
        * IPv6 url parsing enforces brackets around the hostname. (Issue #199)
        
        * Fixed thread race condition in
          ``urllib3.poolmanager.PoolManager.connection_from_host(...)`` (Issue #204)
        
        * ``ProxyManager`` requests now include non-default port in ``Host: ...``
          header. (Issue #217)
        
        * Added HTTPS proxy support in ``ProxyManager``. (Issue #170 #139)
        
        * New ``RequestField`` object can be passed to the ``fields=...`` param which
          can specify headers. (Issue #220)
        
        * Raise ``urllib3.exceptions.ProxyError`` when connecting to proxy fails.
          (Issue #221)
        
        * Use international headers when posting file names. (Issue #119)
        
        * Improved IPv6 support. (Issue #203)
        
        
        1.6 (2013-04-25)
        ++++++++++++++++
        
        * Contrib: Optional SNI support for Py2 using PyOpenSSL. (Issue #156)
        
        * ``ProxyManager`` automatically adds ``Host: ...`` header if not given.
        
        * Improved SSL-related code. ``cert_req`` now optionally takes a string like
          "REQUIRED" or "NONE". Same with ``ssl_version`` takes strings like "SSLv23"
          The string values reflect the suffix of the respective constant variable.
          (Issue #130)
        
        * Vendored ``socksipy`` now based on Anorov's fork which handles unexpectedly
          closed proxy connections and larger read buffers. (Issue #135)
        
        * Ensure the connection is closed if no data is received, fixes connection leak
          on some platforms. (Issue #133)
        
        * Added SNI support for SSL/TLS connections on Py32+. (Issue #89)
        
        * Tests fixed to be compatible with Py26 again. (Issue #125)
        
        * Added ability to choose SSL version by passing an ``ssl.PROTOCOL_*`` constant
          to the ``ssl_version`` parameter of ``HTTPSConnectionPool``. (Issue #109)
        
        * Allow an explicit content type to be specified when encoding file fields.
          (Issue #126)
        
        * Exceptions are now pickleable, with tests. (Issue #101)
        
        * Fixed default headers not getting passed in some cases. (Issue #99)
        
        * Treat "content-encoding" header value as case-insensitive, per RFC 2616
          Section 3.5. (Issue #110)
        
        * "Connection Refused" SocketErrors will get retried rather than raised.
          (Issue #92)
        
        * Updated vendored ``six``, no longer overrides the global ``six`` module
          namespace. (Issue #113)
        
        * ``urllib3.exceptions.MaxRetryError`` contains a ``reason`` property holding
          the exception that prompted the final retry. If ``reason is None`` then it
          was due to a redirect. (Issue #92, #114)
        
        * Fixed ``PoolManager.urlopen()`` from not redirecting more than once.
          (Issue #149)
        
        * Don't assume ``Content-Type: text/plain`` for multi-part encoding parameters
          that are not files. (Issue #111)
        
        * Pass `strict` param down to ``httplib.HTTPConnection``. (Issue #122)
        
        * Added mechanism to verify SSL certificates by fingerprint (md5, sha1) or
          against an arbitrary hostname (when connecting by IP or for misconfigured
          servers). (Issue #140)
        
        * Streaming decompression support. (Issue #159)
        
        
        1.5 (2012-08-02)
        ++++++++++++++++
        
        * Added ``urllib3.add_stderr_logger()`` for quickly enabling STDERR debug
          logging in urllib3.
        
        * Native full URL parsing (including auth, path, query, fragment) available in
          ``urllib3.util.parse_url(url)``.
        
        * Built-in redirect will switch method to 'GET' if status code is 303.
          (Issue #11)
        
        * ``urllib3.PoolManager`` strips the scheme and host before sending the request
          uri. (Issue #8)
        
        * New ``urllib3.exceptions.DecodeError`` exception for when automatic decoding,
          based on the Content-Type header, fails.
        
        * Fixed bug with pool depletion and leaking connections (Issue #76). Added
          explicit connection closing on pool eviction. Added
          ``urllib3.PoolManager.clear()``.
        
        * 99% -> 100% unit test coverage.
        
        
        1.4 (2012-06-16)
        ++++++++++++++++
        
        * Minor AppEngine-related fixes.
        
        * Switched from ``mimetools.choose_boundary`` to ``uuid.uuid4()``.
        
        * Improved url parsing. (Issue #73)
        
        * IPv6 url support. (Issue #72)
        
        
        1.3 (2012-03-25)
        ++++++++++++++++
        
        * Removed pre-1.0 deprecated API.
        
        * Refactored helpers into a ``urllib3.util`` submodule.
        
        * Fixed multipart encoding to support list-of-tuples for keys with multiple
          values. (Issue #48)
        
        * Fixed multiple Set-Cookie headers in response not getting merged properly in
          Python 3. (Issue #53)
        
        * AppEngine support with Py27. (Issue #61)
        
        * Minor ``encode_multipart_formdata`` fixes related to Python 3 strings vs
          bytes.
        
        
        1.2.2 (2012-02-06)
        ++++++++++++++++++
        
        * Fixed packaging bug of not shipping ``test-requirements.txt``. (Issue #47)
        
        
        1.2.1 (2012-02-05)
        ++++++++++++++++++
        
        * Fixed another bug related to when ``ssl`` module is not available. (Issue #41)
        
        * Location parsing errors now raise ``urllib3.exceptions.LocationParseError``
          which inherits from ``ValueError``.
        
        
        1.2 (2012-01-29)
        ++++++++++++++++
        
        * Added Python 3 support (tested on 3.2.2)
        
        * Dropped Python 2.5 support (tested on 2.6.7, 2.7.2)
        
        * Use ``select.poll`` instead of ``select.select`` for platforms that support
          it.
        
        * Use ``Queue.LifoQueue`` instead of ``Queue.Queue`` for more aggressive
          connection reusing. Configurable by overriding ``ConnectionPool.QueueCls``.
        
        * Fixed ``ImportError`` during install when ``ssl`` module is not available.
          (Issue #41)
        
        * Fixed ``PoolManager`` redirects between schemes (such as HTTP -> HTTPS) not
          completing properly. (Issue #28, uncovered by Issue #10 in v1.1)
        
        * Ported ``dummyserver`` to use ``tornado`` instead of ``webob`` +
          ``eventlet``. Removed extraneous unsupported dummyserver testing backends.
          Added socket-level tests.
        
        * More tests. Achievement Unlocked: 99% Coverage.
        
        
        1.1 (2012-01-07)
        ++++++++++++++++
        
        * Refactored ``dummyserver`` to its own root namespace module (used for
          testing).
        
        * Added hostname verification for ``VerifiedHTTPSConnection`` by vendoring in
          Py32's ``ssl_match_hostname``. (Issue #25)
        
        * Fixed cross-host HTTP redirects when using ``PoolManager``. (Issue #10)
        
        * Fixed ``decode_content`` being ignored when set through ``urlopen``. (Issue
          #27)
        
        * Fixed timeout-related bugs. (Issues #17, #23)
        
        
        1.0.2 (2011-11-04)
        ++++++++++++++++++
        
        * Fixed typo in ``VerifiedHTTPSConnection`` which would only present as a bug if
          you're using the object manually. (Thanks pyos)
        
        * Made RecentlyUsedContainer (and consequently PoolManager) more thread-safe by
          wrapping the access log in a mutex. (Thanks @christer)
        
        * Made RecentlyUsedContainer more dict-like (corrected ``__delitem__`` and
          ``__getitem__`` behaviour), with tests. Shouldn't affect core urllib3 code.
        
        
        1.0.1 (2011-10-10)
        ++++++++++++++++++
        
        * Fixed a bug where the same connection would get returned into the pool twice,
          causing extraneous "HttpConnectionPool is full" log warnings.
        
        
        1.0 (2011-10-08)
        ++++++++++++++++
        
        * Added ``PoolManager`` with LRU expiration of connections (tested and
          documented).
        * Added ``ProxyManager`` (needs tests, docs, and confirmation that it works
          with HTTPS proxies).
        * Added optional partial-read support for responses when
          ``preload_content=False``. You can now make requests and just read the headers
          without loading the content.
        * Made response decoding optional (default on, same as before).
        * Added optional explicit boundary string for ``encode_multipart_formdata``.
        * Convenience request methods are now inherited from ``RequestMethods``. Old
          helpers like ``get_url`` and ``post_url`` should be abandoned in favour of
          the new ``request(method, url, ...)``.
        * Refactored code to be even more decoupled, reusable, and extendable.
        * License header added to ``.py`` files.
        * Embiggened the documentation: Lots of Sphinx-friendly docstrings in the code
          and docs in ``docs/`` and on urllib3.readthedocs.org.
        * Embettered all the things!
        * Started writing this file.
        
        
        0.4.1 (2011-07-17)
        ++++++++++++++++++
        
        * Minor bug fixes, code cleanup.
        
        
        0.4 (2011-03-01)
        ++++++++++++++++
        
        * Better unicode support.
        * Added ``VerifiedHTTPSConnection``.
        * Added ``NTLMConnectionPool`` in contrib.
        * Minor improvements.
        
        
        0.3.1 (2010-07-13)
        ++++++++++++++++++
        
        * Added ``assert_host_name`` optional parameter. Now compatible with proxies.
        
        
        0.3 (2009-12-10)
        ++++++++++++++++
        
        * Added HTTPS support.
        * Minor bug fixes.
        * Refactored, broken backwards compatibility with 0.2.
        * API to be treated as stable from this version forward.
        
        
        0.2 (2008-11-17)
        ++++++++++++++++
        
        * Added unit tests.
        * Bug fixes.
        
        
        0.1 (2008-11-16)
        ++++++++++++++++
        
        * First release.
