request rather than a FakeRequest when it sets up the request as a
threadlocal.
- The ``repoze.bfg.traversal.traverse`` API now uses a 'real' WebOb
request rather than a FakeRequest when it calls the traverser.
- The ``repoze.bfg.request.FakeRequest`` class has been removed.
``repoze.bfg.url.route_url``
``repoze.bfg.url.model_url``
``repoze.bfg.url.static_url``
``repoze.bfg.traversal.virtual_root``
Each of these functions now expects to be called with a request
object that has a ``registry`` attribute which represents the
current ZCA registry.
Get rid of extraneous uses of ZCA threadlocal API.

traversal *after* url dispatch via ``<route>`` paths containing the
``*traverse`` element) were broken in 1.1-final and all 1.1 alpha
and beta releases. Views registered without a ``route_name`` route
shadowed views registered with a ``route_name`` inappropriately.

expecting to be able to call the root factory with a bare
``environ`` rather than a request object.
- The ``repoze.bfg.scripting.get_app`` function now expects a
``request`` object as its second argument rather than an
``environ``.

--------
- In previous versions of BFG, the "root factory" (the ``get_root``
callable passed to ``make_app`` or a function pointed to by the
``factory`` attribute of a route) was called with a "bare" WSGI
environment. In this version, and going forward, it will be called
with a ``request`` object. The request object passed to the factory
implements dictionary-like methods in such a way that existing root
factory code which expects to be passed an environ will continue to
work.
Internal
--------
- The request implements dictionary-like methods that mutate and query
the WSGI environ. This is only for the purpose of backwards
compatibility with root factories which expect an ``environ`` rather
than a request.
- The ``repoze.bfg.request.create_route_request_factory`` function,
which returned a request factory was removed in favor of a
``repoze.bfg.request.route_request_interface`` function, which
returns an interface.
- The ``repoze.bfg.request.Request`` class, which is a subclass of
``webob.Request`` now defines its own ``__setattr__``,
``__getattr__`` and ``__delattr__`` methods, which override the
default WebOb behavior. The default WebOb behavior stores
attributes of the request in ``self.environ['webob.adhoc_attrs']``,
and retrieves them from that dictionary during a ``__getattr__``.
This behavior was undesirable for speed and "expectation" reasons.
Now attributes of the ``request`` are stored in ``request.__dict__``
(as you otherwise might expect from an object that did not override
these methods).
- Reverse the order in which the router calls the request factory and
the root factory. The request factory is now called first; the
resulting request is passed to the root factory.
- The ``repoze.bfg.request.request_factory`` function has been
removed. Its functionality is no longer required.
- The "routes root factory" that wraps the default root factory when
there are routes mentioned in the configuration now attaches an
interface to the request via ``zope.interface.directlyProvides``.
This replaces logic in the (now-gone)
``repoze.bfg.request.request_factory`` function.
- The ``route`` and ``view`` ZCML directives now register an interface
as a named utility (retrieved from
``repoze.bfg.request.route_request_interface``) rather than a
request factory (the previous return value of the now-missing
``repoze.bfg.request.create_route_request_factory``.

``webob.Request`` now defines its own ``__setattr__``,
``__getattr__`` and ``__delattr__`` methods, which override the
default WebOb behavior. The default WebOb behavior stores
attributes of the request in ``self.environ['webob.adhoc_attrs']``,
and retrieves them from that dictionary during a ``__getattr__``.
This behavior was undesirable for speed and "expectation" reasons.
Now attributes of the ``request`` are stored in ``request.__dict__``
(as you otherwise might expect from an object that did not override
these methods).
- The router no longer calls ``repoze.bfg.traversal._traverse`` and
does its work "inline" (speed).

directive. If this value is set, it must be an integer representing
the number of seconds which the auth tkt cookie will survive.
Mainly, its existence allows the auth_tkt cookie to survive across
browser sessions.
- The ``reissue_time`` argument to the ``authtktauthenticationpolicy``
ZCML directive now actually works. When it is set to an integer
value, an authticket set-cookie header is appended to the response
whenever a request requires authentication and 'now' minus the
authticket's timestamp is greater than ``reissue_time`` seconds.
- The router now checks for a ``global_response_headers`` attribute of
the request object before returning a response. If this value
exists, it is presumed to be a sequence of two-tuples, representing
a set of headers to append to the 'normal' response headers. This
feature is internal, rather than exposed internally, because it's
unclear whether it will stay around in the long term. It was added
to support the ``reissue_time`` feature of the authtkt
authentication policy.
- The ``authtkt`` authentication policy ``remember`` method now no
longer honors ``token`` or ``userdata`` keyword arguments.

a request that matches using URL dispatch. This feature was only
there to service the ``repoze.bfg.wsgi.wsgiapp2`` decorator and it
did it wrong; use ``*subpath`` instead now.
- The interface generation performed for named request factories had the
wrong base classes.

should be used (**very sparingly**) to retrieve the "current"
request. See the ``repoze.bfg.request`` API documentation for more
information.

``bfg_view`` decorators can now be one of the strings ``GET``,
``POST``, ``PUT``, ``DELETE``, or ``HEAD`` instead of a reference to
the respective interface type imported from
``repoze.bfg.interfaces``.

the request machinery will attempt to decode values from the utf-8
encoding to Unicode automatically when they are obtained via
``request.params``, ``request.GET``, and ``request.POST``. The
previous behavior of BFG was to return a bytestring when a value was
accessed in this manner. This change will break form handling code
in apps that rely on values from those APIs being considered
bytestrings. If you are manually decoding values from form
submissions in your application, you'll either need to change the
code that does that to expect Unicode values from
``request.params``, ``request.GET`` and ``request.POST``, or you'll
need to explicitly reenable the previous behavior. To reenable the
previous behavior, add the following to your application's
``configure.zcml``::
<subscriber for="repoze.bfg.interfaces.INewRequest"
handler="repoze.bfg.request.make_request_ascii"/>
See also the documentation in the "Views" chapter of the BFG docs
entitled "Using Views to Handle Form Submissions (Unicode and
Character Set Issues)".

# request methods within ``router.py`` when constructing a request
# object rather than using ``alsoProvides`` to attach the proper
# interface to an unsubclassed webob.Request. This pattern is purely
# an optimization (e.g. preventing calls to ``alsoProvides`` means the
# difference between 590 r/s and 690 r/s on a MacBook 2GHz).
