def excview_tween_factory(handler, registry): |

""" A :term:`tween` factory which produces a tween that catches an |
|
24 |
exception raised by downstream tweens (or the main Pyramid request |
|
25 |
handler) and, if possible, converts it into a Response using an |
e2e51b
|
26 |
:term:`exception view`. |

.. versionchanged:: 1.9 |

The ``request.response`` will be remain unchanged even if the tween |
|
30 |
handles an exception. Previously it was deleted after handling an |
|
31 |
exception. |
|
32 |
|
|
33 |
Also, ``request.exception`` and ``request.exc_info`` are only set if |
|
34 |
the tween handles an exception and returns a response otherwise they |
|
35 |
are left at their original values. |
