-------- - 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.

2010-09-13- Call response callbacks *after* INewResponse event.Chris McDonough
- Rearrange router logic so that start_response is not called until there is no chance of an exception occurring.
2010-09-13FeaturesChris McDonough
-------- - 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.
2010-09-12- The BFG router now emits an additional event unconditionally at theChris McDonough
end of request processing: ``repoze.bfg.interfaces.IFinishedRequest``. This event is meant to be used when it is necessary to perform unconditional cleanup after request processing. See the ``repoze.bfg.events.FinishedRequest`` class documentation for more information. - The ``repoze.bfg.interfaces.IWSGIApplicationCreatedEvent`` event interface was renamed to ``repoze.bfg.interfaces.IApplicationCreated``. Likewise, the ``repoze.bfg.events.WSGIApplicationCreatedEvent`` class was renamed to ``repoze.bfg.events.ApplicationCreated``. The older aliases will continue to work indefinitely. - The ``repoze.bfg.interfaces.IAfterTraversal`` event interface was renamed to ``repoze.bfg.interfaces.IContextFound``. Likewise, the ``repoze.bfg.events.AfterTraveral`` class was renamed to ``repoze.bfg.events.ContextFound``. The older aliases will continue to work indefinitely.

2010-09-09FeaturesChris McDonough
-------- - In support of making it easier to configure applications which are "secure by default", a default permission feature was added. If supplied, the default permission is used as the permission string to all view registrations which don't otherwise name a permission. These APIs are in support of that: - A new constructor argument was added to the Configurator: ``default_permission``. - A new method was added to the Configurator: ``set_default_permission``. - A new ZCML directive was added: ``default_permission``. Documentation ------------- - Added documentation for the ``default_permission`` ZCML directive. - Added documentation for the ``default_permission`` constructor value and the ``set_default_permission`` method in the Configurator API documentation. - Added a new section to the "security" chapter named "Setting a Default Permission". - Document ``renderer_globals_factory`` and ``request_factory`` arguments to Configurator constructor.

2010-09-08- The ``repoze.bfg.interfaces`` API documentation page is now renderedChris McDonough
via ``repoze.sphinx.autointerface``. - The URL Dispatch narrative chapter now refers to the ``interfaces`` chapter to explain the API of an ``IRoute`` object. - ``tests_require`` now includes ``repoze.sphinx.autointerface`` as a dependency.
2010-09-08- The ``repoze.bfg.urldispatch.Route`` constructor (not an API) nowChris McDonough
accepts a different ordering of arguments. Previously it was ``(pattern, name, factory=None, predicates=())``. It is now ``(name, pattern, factory=None, predicates=())``. This is in support of consistency with ``configurator.add_route``. - The ``repoze.bfg.urldispatch.RoutesMapper.connect`` method (not an API) now accepts a different ordering of arguments. Previously it was ``(pattern, name, factory=None, predicates=())``. It is now ``(name, pattern, factory=None, predicates=())``. This is in support of consistency with ``configurator.add_route``. - The ``repoze.bfg.urldispatch.RoutesMapper`` object now has a ``get_route`` method which returns a single Route object or ``None``. - A new interface ``repoze.bfg.interfaces.IRoute`` was added. The ``repoze.bfg.urldispatch.Route`` object implements this interface. - The canonical attribute for accessing the routing pattern from a route object is now ``pattern`` rather than ``path``. - The argument to ``repoze.bfg.configuration.Configurator.add_route`` which was previously called ``path`` is now called ``pattern`` for better explicability. For backwards compatibility purposes, passing a keyword argument named ``path`` to ``add_route`` will still work indefinitely. - The ``path`` attribute to the ZCML ``route`` directive is now named ``pattern`` for better explicability. The older ``path`` attribute will continue to work indefinitely. - All narrative, API, and tutorial docs which referred to a route pattern as a ``path`` have now been updated to refer to them as a ``pattern``. - The routesalchemy template has been updated to use ``pattern`` in its route declarations rather than ``path``.

2010-09-06- The ``repoze.bfg.interfaces.INewResponse`` interface now includes aChris McDonough
``request`` attribute; as a result, a handler for INewResponse now has access to the request which caused the response. - The INewResponse event is now not sent to listeners if the response returned by view code (or a renderer) is not a "real" response (e.g. if it does not have ``.status``, ``.headerlist`` and ``.app_iter`` attribtues).
2010-09-05- Each of the follow methods of the Configurator now allow theChris McDonough

2010-09-05DocumentationChris McDonough
------------- - 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.

2010-08-08- New public interface: ``repoze.bfg.exceptions.IExceptionResponse``.Chris McDonough
This interface is provided by all internal exception classes (such as ``repoze.bfg.exceptions.NotFound`` and ``repoze.bfg.exceptions.Forbidden``), instances of which are both exception objects and can behave as WSGI response objects. This interface is made public so that exception classes which are also valid WSGI response factories can be configured to implement them or exception instances which are also or response instances can be configured to provide them. - New API class: ``repoze.bfg.view.AppendSlashNotFoundViewFactory`` (undoes previous custom_notfound_view on request passsed to append_slash_notfound_view). - Previously, two default view functions were registered at Configurator setup (one for ``repoze.bfg.exceptions.NotFound`` named ``default_notfound_view`` and one for ``repoze.bfg.exceptions.Forbidden`` named ``default_forbidden_view``) to render internal exception responses. Those default view functions have been removed, replaced with a generic default view function which is registered at Configurator setup for the ``repoze.bfg.interfaces.IExceptionResponse`` interface that simply returns the exception instance; the ``NotFound` and ``Forbidden`` classes are now still exception factories but they are also response factories which generate instances that implement the new ``repoze.bfg.interfaces.IExceptionResponse`` interface.
2010-08-07FeaturesChris McDonough
-------- - There can only be one Not Found view in any ``repoze.bfg`` application. If you use ``repoze.bfg.view.append_slash_notfound_view`` as the Not Found view, it still must generate a NotFound response when it cannot redirect to a slash-appended URL; this not found response will be visible to site users. As of this release, if you wish to use a custom notfound view callable when ``append_slash_notfound_view`` does not redirect to a slash-appended URL, use a wrapper function as the ``repoze.bfg.exceptions.NotFound`` view; have this wrapper attach a view callable which returns a response to the request object named ``custom_notfound_view`` before calling ``append_slash_notfound_view``. For example:: from webob.exc import HTTPNotFound from repoze.bfg.exceptions import NotFound from repoze.bfg.view import append_slash_notfound_view def notfound_view(exc, request): def fallback_notfound_view(exc, request): return HTTPNotFound('It aint there, stop trying!') request.fallback_notfound_view = fallback_notfound_view return append_slash_notfound_view(exc, request) config.add_view(notfound_view, context=NotFound) ``custom_notfound_view`` must adhere to the two-argument view callable calling convention of ``(context, request)`` (``context`` will be the exception object). If ``custom_notfound_view`` is not found on the request object, a default notfound response will be generated when the ``append_slash_notfound_view`` doesn't redirect to a slash-appended URL. Documentation -------------- - Expanded the "Cleaning Up After a Request" section of the URL Dispatch narrative chapter. - Expanded the "Redirecting to Slash-Appended Routes" section of the URL Dispatch narrative chapter.

2010-07-24Remove match_val feature: it's a pretty nuisanceChris McDonough
2010-07-24- A new method of the ``Configurator`` exists:Chris McDonough
``set_request_factory``. If used, this method will set the factory used by the :mod:`repoze.bfg` router to create all request objects. - The ``Configurator`` constructor takes an additional argument: ``request_factory``. If used, this argument will set the factory used by the :mod:`repoze.bfg` router to create all request objects. - The ``Hooks`` narrative chapter now contains a section about changing the request factory.
2010-07-23- The ``Hybrid`` narrative chapter now contains a description of theChris McDonough
``traverse`` route argument. - Fix route ZCML directive to use traverse.
2010-07-23- New argument to ``repoze.bfg.configuration.Configurator.add_route``Chris McDonough
and the ``route`` ZCML directive: ``traverse``. If you would like to cause the ``context`` to be something other than the ``root`` object when this route matches, you can spell a traversal pattern as the ``traverse`` argument. This traversal pattern will be used as the traversal path: traversal will begin at the root object implied by this route (either the global root, or the object returned by the ``factory`` associated with this route). The syntax of the ``traverse`` argument is the same as it is for ``path``. For example, if the ``path`` provided is ``articles/:article/edit``, and the ``traverse`` argument provided is ``/:article``, when a request comes in that causes the route to match in such a way that the ``article`` match value is '1' (when the request URI is ``/articles/1/edit``), the traversal path will be generated as ``/1``. This means that the root object's ``__getitem__`` will be called with the name ``1`` during the traversal phase. If the ``1`` object exists, it will become the ``context`` of the request. The Traversal narrative has more information about traversal. If the traversal path contains segment marker names which are not present in the path argument, a runtime error will occur. The ``traverse`` pattern should not contain segment markers that do not exist in the ``path``. A similar combining of routing and traversal is available when a route is matched which contains a ``*traverse`` remainder marker in its path. The ``traverse`` argument allows you to associate route patterns with an arbitrary traversal path without using a a ``*traverse`` remainder marker; instead you can use other match information. Note that the ``traverse`` argument is ignored when attached to a route that has a ``*traverse`` remainder marker in its path.
2010-07-15FeaturesChris McDonough
-------- - New view predicate: match_val. The ``match_val`` value represents the presence of a value in the structure added to the request named ``matchdict`` during URL dispatch representing the match values from the route pattern (e.g. if the route pattern has ``:foo`` in it, and the route matches, a key will exist in the matchdict named ``foo``). Like all other view predicates, this feature is exposed via the ``bfg_view`` API, the Configurator ``add_view`` API, and the ZCML ``view`` directive. Documentation ------------- - API documentation for the ``add_view`` method of the configurator changed to include ``match_val``. - ZCML documentation for ``view`` ZCML directive changed to include ``match_val``. - The ``Views`` narrative chapter now contains a description of the ``match_val`` predicate. Bug Fixes --------- - The ``header`` predicate (when used as either a view predicate or a route predicate) had a problem when specified with a name/regex pair. When the header did not exist in the headers dictionary, the regex match could be fed ``None``, causing it to throw a ``TypeError: expected string or buffer`` exception. Now, the predicate returns False as intended. Internal -------- - Remove ``repoze.bfg.configuration.isclass`` function in favor of using ``inspect.isclass``.
2010-07-13docs tweaksChris McDonough
2010-07-04documentation updatesChris McDonough
2010-07-02- The ``repoze.bfg.url.route_url`` API has changed. If a keywordChris McDonough
``_app_url`` is present in the arguments passed to ``route_url``, this value will be used as the protocol/hostname/port/leading path prefix of the generated URL. For example, using an ``_app_url`` of ``http://example.com:8080/foo`` would cause the URL ``http://example.com:8080/foo/fleeb/flub`` to be returned from this function if the expansion of the route pattern associated with the ``route_name`` expanded to ``/fleeb/flub``. - It is now possible to use a URL as the ``name`` argument fed to ``repoze.bfg.configuration.Configurator.add_static_view``. When the name argument is a URL, the ``repoze.bfg.url.static_url`` API will generate join this URL (as a prefix) to a path including the static file name. This makes it more possible to put static media on a separate webserver for production, while keeping static media package-internal and served by the development webserver during development.
