Pyramid Pluggable Session 0.0.0a2

Description:

pyramid pluggable session 0.0.0a2

pyramid_pluggable_session
Want to be able to change out session backends using a simple configuration
change, want to store your session data in a new location but re-implementing
ISession from Pyramid looks too daunting, fear not, pyramid_pluggable_session
makes this really simple.

Is this a pyramid_beaker replacement?
Yes. Although I’ve already been told that unless I implement ALL existing
beaker backends that I am not doing it right, so I am hereby doing it wrong
;-).

Pull requests
Want to add a new backend? Perfect. Want to write some tests? Documentation?

0.0.0a2

Add better protection against session fixation:

Upon failure to deserialize/unpack/expiration of session a new session id
is generated.
Upon calling invalidate() a new session is generated with a new session
id

Add more clean-up using the new clear() functionality. When a session fails
to deserialize, we remove it from the backends, if a session fails to unpack
we remove it from the backends, and if it has expired we also remove it from
the backends.
Update the included backends memory/file/chain to add the new clear()
function required by IPlugSession.
Add clear() to IPlugSession interface to allow the session to explicitly have
the backend plugs remove the session data associated with a certain session
id.
On _save_session we set the cookie to response that is provided to us by the
callback, and not request.response which may not be the users response.
