hyperframe 3.0.1

HTTP/2 framing layer for Python

======================================
hyperframe: Pure-Python HTTP/2 framing
======================================

.. image:: https://travis-ci.org/python-hyper/hyperframe.png?branch=master
:target: https://travis-ci.org/python-hyper/hyperframe

This library contains the HTTP/2 framing code used in the `hyper`_ project. It
provides a pure-Python codebase that is capable of decoding a binary stream
into HTTP/2 frames.

This library is used directly by `hyper`_ and a number of other projects to
provide HTTP/2 frame decoding logic.

Release History
===============

3.0.1 (2016-01-08)
------------------

**Bugfixes**

- Fix issue where unpadded DATA, PUSH_PROMISE and HEADERS frames that had empty
bodies would raise ``InvalidPaddingError`` exceptions when parsed.

3.0.0 (2016-01-08)
------------------

**Backwards Incompatible API Changes**

- Parsing padded frames that have invalid padding sizes now throws an
``InvalidPaddingError``.

2.2.0 (2015-10-15)
------------------

**API Changes**

- When an unknown frame is encountered, ``parse_frame_header`` now throws a
``ValueError`` subclass: ``UnknownFrameError``. This subclass contains the
frame type and the length of the frame body.

2.1.0 (2015-10-06)
------------------

**API Changes**

- Frames parsed from binary data now carry a ``body_len`` attribute that
matches the frame length (minus the frame header).

2.0.0 (2015-09-21)
------------------

**API Changes**

- Attempting to parse unrecognised frames now throws ``ValueError`` instead of
``KeyError``. Thanks to @Kriechi!
- Flags are now validated for correctness, preventing setting flags that
``hyperframe`` does not recognise and that would not serialize. Thanks to
@mhils!
- Frame properties can now be initialized in the constructors. Thanks to @mhils
and @Kriechi!
- Frames that cannot be sent on a stream now have their stream ID defaulted
to ``0``. Thanks to @Kriechi!

**Other Changes**

- Frames have a more useful repr. Thanks to @mhils!

1.1.1 (2015-07-20)
------------------

- Fix a bug where ``FRAME_MAX_LEN`` was one byte too small.

1.1.0 (2015-06-28)
------------------

- Add ``body_len`` property to frames to enable introspection of the actual
frame length. Thanks to @jdecuyper!

1.0.1 (2015-06-27)
------------------

- Fix bug where the frame header would have an incorrect length added to it.

1.0.0 (2015-04-12)
------------------

- Initial extraction from `hyper`_.
