``request.response_content_type = 'foo'``. Assignments and mutations of
the following request attributes that were considered by the framework for
response influence are now deprecated: ``response_content_type``,
``response_headerlist``, ``response_status``, ``response_charset``, and
``response_cache_for``. Instead of assigning these to the request object
for detection by the rendering machinery, users should use the appropriate
API of the Response object created by accessing ``request.response``
(e.g. ``request.response_content_type = 'abc'`` ->
``request.response.content_type = 'abc'``).
- Custom request objects are now required to have a ``response`` attribute
(or reified property) if they are meant to be used with renderers. This
``response`` attribute should be an instance of the class
``pyramid.response.Response``.
- The JSON and string renderer factories now use
``request.response.content_type`` rather than
``request.response_content_type``. They determine whether they should set
the content type of the response by comparing the response's content type
against the default (usually ``text/html``); if the content type is not the
default, the renderer changes the content type (to ``application/json`` or
``text/plain`` for JSON and string renderers respectively).
- Made it possible to assign to and delete
``pyramid.testing.DummyRequest.registry`` (bugfix).

--------
- Compatibility with WebOb 1.0.
Requirements
------------
- Now requires WebOb >= 1.0.
Backwards Incompatibilities
---------------------------
- Due to changes introduced WebOb 1.0, the
``repoze.bfg.request.make_request_ascii`` event subscriber no longer
works, so it has been removed. This subscriber was meant to be used
in a deployment so that code written before BFG 0.7.0 could run
unchanged. At this point, such code will need to be rewritten to
expect Unicode from ``request.GET``, ``request.POST`` and
``request.params`` or it will need to be changed to use
``request.str_POST``, ``request.str_GET`` and/or
``request.str_params`` instead of the non-``str`` versions of same,
as the non-``str`` versions of the same APIs always now perform
decoding to Unicode.

--------
- A ``request.matched_route`` attribute is now added to the request
when a route has matched. Its value is the "route" object that
matched (see the ``IRoute`` interface within
``repoze.bfg.interfaces`` API documentation for the API of a route
object).
- The ``exception`` attribute of the request is now set slightly
earlier and in a slightly different set of scenarios, for benefit of
"finished callbacks" and "response callbacks". In previous
versions, the ``exception`` attribute of the request was not set at
all if an exception view was not found. In this version, the
``request.exception`` attribute is set immediately when an exception
is caught by the router, even if an exception view could not be
found.
Backwards Incompatibilities
---------------------------
- The router no longer sets the value ``wsgiorg.routing_args`` into
the environ when a route matches. The value used to be something
like ``((), matchdict)``. This functionality was only ever
obliquely referred to in change logs; it was never documented as an
API.
- The ``exception`` attribute of the request now defaults to ``None``.
In prior versions, the ``request.exception`` attribute did not exist
if an exception was not raised by user code during request
processing; it only began existence once an exception view was
found.
Deprecations
------------
- References to the WSGI environment values ``bfg.routes.matchdict``
and ``bfg.routes.route`` were removed from documentation. These
will stick around internally for several more releases, but it is
``request.matchdict`` and ``request.matched_route`` are now the
"official" way to obtain the matchdict and the route object which
resulted in the match.
Documentation
-------------
- Added two sections to the "Hooks" chapter of the documentation:
"Using Response Callbacks" and "Using Finished Callbacks".
- Added documentation of the ``request.exception`` attribute to the
``repoze.bfg.request.Request`` API documentation.
- Added glossary entries for "response callback" and "finished
callback".
- The "Request Processing" narrative chapter has been updated to note
finished and response callback steps.
|
|
-------------
- Add an API chapter for the ``repoze.bfg.request`` module, which
includes documentation for the ``repoze.bfg.request.Request`` class
(the "request object").
- Modify the "Request and Response" narrative chapter to reference the
new ``repoze.bfg.request`` API chapter. Some content was moved from
this chapter into the API documentation itself.
Features
--------
- A new ``repoze.bfg.request.Request.add_response_callback`` API has
been added. This method is documented in the new
``repoze.bfg.request`` API chapter. It can be used to influence
response values before a concrete response object has been created.
Internal
--------
- The (internal) feature which made it possible to attach a
``global_response_headers`` attribute to the request (which was
assumed to contain a sequence of header key/value pairs which would
later be added to the response by the router), has been removed.
The functionality of
``repoze.bfg.request.Request.add_response_callback`` takes its
place.

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