requests_SSL_v3 2.1.0

Python HTTP for Humans.

Requests SSL_v3 with OpenSSL
=========================

Why did I make this fork?
-------------------------
If you receive errors such as:

    SSLError: [Errno 1] _ssl.c:504: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version
Try using this fork. This is mainly an issue with Ubuntu's OpenSSL lib not playing nice with the python ssl library.
I will try and stay as up to date as I can with the [official requests repo](https://github.com/kennethreitz/requests
Why not open an issue on requests?
----------------------------------

If you search the issues of official request repo, you'll see many issues
regarding the inability to easily select SSL versions. The issue seems to be
caused by OpenSSL on some Ubuntu machines, but requests has not adapted to this
issue.
The resolution to most issues is "upgrade your Python" or "upgrade OpenSSL",
neither of which have worked for me. So this fork will contain my hack
found in [#1788](https://github.com/kennethreitz/requests/pull/1788)
This hack is a more updated version of (https://github.com/kennethreitz/requests/pull/799) to make
requests work with sites that enforce SSLv3.

Requests is an Apache2 Licensed HTTP library, written in Python, for human
beings.

Most existing Python modules for sending HTTP requests are extremely
verbose and cumbersome. Python's builtin urllib2 module provides most of
the HTTP capabilities you should need, but the api is thoroughly broken.
It requires an enormous amount of work (even method overrides) to
perform the simplest of tasks.

Things shouldn't be this way. Not in Python.

.. code-block:: pycon

    >>> r = requests.get('https://api.github.com', auth=('user', 'pass'))
    >>> r.status_code
    204
    >>> r.headers['content-type']
    'application/json'
    >>> r.text
    ...

See `the same code, without Requests <https://gist.github.com/973705>`_.

Requests allow you to send HTTP/1.1 requests. You can add headers, form data,
multipart files, and parameters with simple Python dictionaries, and access the
response data in the same way. It's powered by httplib and `urllib3
<https://github.com/shazow/urllib3>`_, but it does all the hard work and crazy
hacks for you.


Features
--------

- International Domains and URLs
- Keep-Alive & Connection Pooling
- Sessions with Cookie Persistence
- Browser-style SSL Verification
- Basic/Digest Authentication
- Elegant Key/Value Cookies
- Automatic Decompression
- Unicode Response Bodies
- Multipart File Uploads
- Connection Timeouts
- Thread-safety
- HTTP(S) proxy support


Installation
------------

To install Requests, simply:

.. code-block:: bash

    $ pip install requests

Or, if you absolutely must:

.. code-block:: bash

    $ easy_install requests

But, you really shouldn't do that.

-------------

Documentation is available at http://docs.python-requests.org/.

Release History
---------------

2.1.0 (2013-12-05)
++++++++++++++++++

- Updated CA Bundle, of course.
- Clean up connections when we hit problems during chunked upload, rather than leaking them.
- Return connections to the pool when a chunked upload is successful, rather than leaking it.
- Match the HTTPbis recommendation for HTTP 301 redirects.
- Prevent hanging when using streaming uploads and Digest Auth when a 401 is received.
- Values of headers set by Requests are now always the native string type.
- Fix previously broken SNI support.
- Fix accessing HTTP proxies using proxy authentication.
- Unencode HTTP Basic usernames and passwords extracted from URLs.
- Support for IP address ranges for no_proxy environment variable
- Parse headers correctly when users override the default ``Host:`` header.
- Avoid munging the URL in case of case-sensitive servers.
- Looser URL handling for non-HTTP/HTTPS urls.
- Accept unicode methods in Python 2.6 and 2.7.
- More resilient cookie handling.
- Make ``Response`` objects pickleable.
- Actually added MD5-sess to Digest Auth instead of pretending to like last time.
- Updated internal urllib3.
- Fixed @Lukasa's lack of taste.

2.0.1 (2013-10-24)
++++++++++++++++++

- Updated included CA Bundle with new mistrusts and automated process for the future
- Added MD5-sess to Digest Auth
- Accept per-file headers in multipart file POST messages.
- Fixed: Don't send the full URL on CONNECT messages.
- Fixed: Correctly lowercase a redirect scheme.
- Fixed: Cookies not persisted when set via functional API.
- Fixed: Translate urllib3 ProxyError into a requests ProxyError derived from ConnectionError.
- Updated internal urllib3 and chardet.

2.0.0 (2013-09-24)
++++++++++++++++++

**API Changes:**

- Keys in the Headers dictionary are now native strings on all Python versions,
  i.e. bytestrings on Python 2, unicode on Python 3.
- Proxy URLs now *must* have an explicit scheme. A ``MissingSchema`` exception
  will be raised if they don't.
- Timeouts now apply to read time if ``Stream=False``.
- ``RequestException`` is now a subclass of ``IOError``, not ``RuntimeError``.
- Added new method to ``PreparedRequest`` objects: ``PreparedRequest.copy()``.
- Added new method to ``Session`` objects: ``Session.update_request()``. This
  method updates a ``Request`` object with the data (e.g. cookies) stored on
  the ``Session``.
- Added new method to ``Session`` objects: ``Session.prepare_request()``. This
  method updates and prepares a ``Request`` object, and returns the
  corresponding ``PreparedRequest`` object.
- Added new method to ``HTTPAdapter`` objects: ``HTTPAdapter.proxy_headers()``.
  This should not be called directly, but improves the subclass interface.
- ``httplib.IncompleteRead`` exceptions caused by incorrect chunked encoding
  will now raise a Requests ``ChunkedEncodingError`` instead.
- Invalid percent-escape sequences now cause a Requests ``InvalidURL``
  exception to be raised.
- HTTP 208 no longer uses reason phrase ``"im_used"``. Correctly uses
  ``"already_reported"``.
- HTTP 226 reason added (``"im_used"``).

**Bugfixes:**

- Vastly improved proxy support, including the CONNECT verb. Special thanks to
  the many contributors who worked towards this improvement.
- Cookies are now properly managed when 401 authentication responses are
  received.
- Chunked encoding fixes.
- Support for mixed case schemes.
- Better handling of streaming downloads.
- Retrieve environment proxies from more locations.
- Minor cookies fixes.
- Improved redirect behaviour.
- Improved streaming behaviour, particularly for compressed data.
- Miscellaneous small Python 3 text encoding bugs.
- ``.netrc`` no longer overrides explicit auth.
- Cookies set by hooks are now correctly persisted on Sessions.
- Fix problem with cookies that specify port numbers in their host field.
- ``BytesIO`` can be used to perform streaming uploads.
- More generous parsing of the ``no_proxy`` environment variable.
- Non-string objects can be passed in data values alongside files.

  requests
- Add ``elapsed`` attribute to ``Response`` objects to time how long a request
  took.
- Fix ``RequestsCookieJar``
- Sessions and Adapters are now picklable, i.e., can be used with the
  multiprocessing library
