Python-spdylay is a Python SPDY library on top of Spdylay C
|
|
|
|
|
library. It supports SPDY/2 and SPDY/3 protocol.
|
|
|
|
|
|
|
|
|
|
It does not perform any I/O operations. When the library needs them,
|
|
|
|
|
it calls the callback functions provided by the application. It also
|
|
|
|
|
does not include any event polling mechanism, so the application can
|
|
|
|
|
freely choose the way of handling events.
|
|
|
|
|
|
|
|
|
|
It provides almost all API Spdylay provides with Pythonic fashion.
|
|
|
|
|
|
|
|
|
|
The core library API works with Python 2 and 3. But
|
|
|
|
|
``ThreadedSPDYServer`` requires Python 3.3 because it uses TLS NPN
|
|
|
|
|
extension.

Installation
|
|
|
|
|
============
|
|
|
|
|
|
|
|
|
|
First install Spdylay library. You can grab a source distribution from
|
|
|
|
|
`sf.net download page
|
|
|
|
|
<http://sourceforge.net/projects/spdylay/files/stable/>`_
|
|
|
|
|
or `clone git repository <https://github.com/tatsuhiro-t/spdylay>`_.
|
|
|
|
|
|
|
|
|
|
See `Spdylay documentation
|
|
|
|
|
<http://spdylay.sourceforge.net/package_README.html>`_ for the
|
|
|
|
|
required packages and how to build Spdylay from git repository.
|
|
|
|
|
|
|
|
|
|
After Spdylay is installed, run ``build_ext`` command to build
|
|
|
|
|
extension module::
|
|
|
|
|
|
|
|
|
|
$ python setup.py build_ext
|
|
|
|
|
|
|
|
|
|
If you installed Spdylay library in other than standard location, use
|
|
|
|
|
``--include-dirs`` and ``--library-dirs`` to specify header file and
|
|
|
|
|
library locations respectively.
