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.

-------- - 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.
2010-07-02- 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.
2010-04-25Allow default exception views to handle the case where they'veChris McDonough
been registered explicitly via set_XXX_view instead of as exception views.
2010-04-25Make default_notfound_view and default_forbidden_view expect an exception asChris McDonough
a context. Cause append_slash_notfound_view to work in case it is registered via set_notfound_view.

2010-04-18- Use "Venusian" (`http://docs.repoze.org/venusianChris McDonough
<http://docs.repoze.org/venusian>`) to perform ``bfg_view`` decorator scanning rather than relying on a BFG-internal decorator scanner. (Truth be told, Venusian is really just a generalization of the BFG-internal decorator scanner). - A new install-time dependency on the ``venusian`` distribution was added. - Remove ``repoze.bfg.compat.pkgutil_26.py`` and import alias ``repoze.bfg.compat.walk_packages``. These were only required by internal scanning machinery; Venusian replaced the internal scanning machinery, so these are no longer required.

2009-12-19- Add a ``custom_predicates`` argument to the ``Configurator``Chris McDonough
``add_view`` method, the ``bfg_view`` decorator and the attribute list of the ZCML ``view`` directive. If ``custom_predicates`` is specified, it must be a sequence of predicate callables (a predicate callable accepts two arguments: ``context`` and ``request`` and returns ``True`` or ``False``). The associated view callable will only be invoked if all custom predicates return ``True``. Use one or more custom predicates when no existing predefined predicate is useful. Predefined and custom predicates can be mixed freely. - Add a ``custom_predicates`` argument to the ``Configurator`` ``add_route`` and the attribute list of the ZCML ``route`` directive. If ``custom_predicates`` is specified, it must be a sequence of predicate callables (a predicate callable accepts two arguments: ``context`` and ``request`` and returns ``True`` or ``False``). The associated route will match will only be invoked if all custom predicates return ``True``, else route matching continues. Use one or more custom predicates when no existing predefined predicate is useful. Predefined and custom predicates can be mixed freely.
2009-12-09- General documentation freshening which takes imperativeChris McDonough
configuration into account in more places and uses glossary references more liberally.
2009-11-27- The ``repoze.bfg.testing.setUp`` function now accepts three extraChris McDonough
optional keyword arguments: ``registry``, ``request`` and ``hook_zca``. If the ``registry`` argument is not ``None``, the argument will be treated as the registry that is set as the "current registry" (it will be returned by ``repoze.bfg.threadlocal.get_current_registry``) for the duration of the test. If the ``registry`` argument is ``None`` (the default), a new registry is created and used for the duration of the test. The value of the ``request`` argument is used as the "current request" (it will be returned by ``repoze.bfg.threadlocal.get_current_request``) for the duration of the test; it defaults to ``None``. If ``hook_zca`` is ``True`` (the default), the ``zope.component.getSiteManager`` function will be hooked with a function that returns the value of ``registry`` (or the default-created registry if ``registry`` is ``None``) instead of the registry returned by ``zope.component.getGlobalSiteManager``, causing the Zope Component Architecture API (``getSiteManager``, ``getAdapter``, ``getUtility``, and so on) to use the registry we're using for testing instead of the global ZCA registry. - The ``repoze.bfg.testing.tearDown`` function now accepts an ``unhook_zca`` argument. If this argument is ``True`` (the default), ``zope.component.getSiteManager.reset()`` will be called, causing the "base" registry to once again start returnining the result of ``zope.component.getSiteManager``. - Remove hook_zca and unhook_zca methods from Configurator.

2009-11-19- Each of the ``repoze.bfg.view.render_view``,Chris McDonough
``repoze.bfg.view.render_view_to_iterable``, ``repoze.bfg.view.render_view_to_response``, ``repoze.bfg.view.append_slash_notfound_view``, ``repoze.bfg.view.default_notfound_view``, ``repoze.bfg.view.default_forbidden_view``, and the ``repoze.bfg.configuration.rendered_response`` functions now expects to be called with a request object that has a ``registry`` attribute which represents the current ZCA registry. This should only be a problem when passing a custom request object to code which ends up calling these functions in a unit test. To retrofit tests that end up calling these functions which expect to be able to use a non-registry-aware request object, use the ``repoze.bfg.threadlocal.get_current_request`` API in the test to create the request; this will return a ``repoze.bfg.testing.DummyRequest`` that has the current registry as its ``registry`` attribute. Alternatively, use the ``repoze.bfg.threadlocal.get_current_registry`` API: call this function and add an attribute to your unit test request object named ``registry`` with the result. - The ``repoze.bfg.view.derive_view`` callable has been removed. Use ``repoze.bfg.configuration.Configurator.derive_view`` instead (still not an API, however).

2009-11-01- The ``repoze.bfg.functional`` module was renamed toChris McDonough
``repoze.bfg.compat``.
2009-10-29- The ``repoze.bfg.request.Request`` class, which is a subclass ofChris McDonough
``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).

2009-10-21- Change how ``bfg_view`` decorator works when used as a class methodChris McDonough
decorator. In 1.1a7, it actually tried to grope every class in scanned package at startup time looking for methods, which led to some strange symptoms (e.g. ``AttributeError: object has no attribute __provides__``). Now, instead of groping methods at startup time, we just cause the ``bfg_view`` decorator itself to populate its class' __dict__ when its used inside a class as a method decorator. This is essentially a reversion back to 1.1a6 "grokking" behavior plus some special magic for using the ``bfg_view`` decorator as method decorator inside the ``bfg_view`` class itself.
2009-10-18- The ``@bfg_view`` decorator can now be used against a class method::Chris McDonough
from webob import Response from repoze.bfg.view import bfg_view class MyView(object): def __init__(self, context, request): self.context = context self.request = request @bfg_view(name='hello') def amethod(self): return Response('hello from %s!' % self.context) When the bfg_view decorator is used against a class method, a view is registered for the *class* (it's a "class view" where the "attr" happens to be the method they're attached to), so the view class must have a suitable constructor.
2009-10-18- More than one ``@bfg_view`` decorator may now be stacked on top ofChris McDonough
any number of others. Each invocation of the decorator registers a single view. For instance, the following combination of decorators and a function will register two views:: from repoze.bfg.view import bfg_view @bfg_view(name='edit') @bfg_view(name='change') def edit(context, request): pass This makes it possible to associate more than one view configuration for a single callable without requiring ZCML.
2009-10-14- Add ``xhr``, ``accept``, and ``header`` view configurationChris McDonough
predicates to ZCML view declaration, ZCML route declaration, and ``bfg_view`` decorator. See the ``Views`` narrative documentation chapter for more information about these predicates.

2009-09-30Use API to get routes.Chris McDonough
2009-09-30- For behavior like Django's ``APPEND_SLASH=True``, use theChris McDonough
``repoze.bfg.view.append_slash_notfound_view`` view as the Not Found view in your application. When this view is the Not Found view (indicating that no view was found), and any routes have been defined in the configuration of your application, if the value of ``PATH_INFO`` does not already end in a slash, and if the value of ``PATH_INFO`` *plus* a slash matches any route's path, do an HTTP redirect to the slash-appended PATH_INFO. Note that this will *lose* ``POST`` data information (turning it into a GET), so you shouldn't rely on this to redirect POST requests.
2009-09-30- The import of ``repoze.bfg.view.NotFound`` is deprecated in favor ofChris McDonough
``repoze.bfg.exceptions.NotFound``. The old location still functions, but emits a deprecation warning. - The import of ``repoze.bfg.security.Unauthorized`` is deprecated in favor of ``repoze.bfg.exceptions.Forbidden``. The old location still functions but emits a deprecation warning. The rename from ``Unauthorized`` to ``Forbidden`` brings parity to the the name of the exception and the system view it invokes when raised. - New ``repoze.bfg.exceptions`` module was created to house exceptions that were previously sprinkled through various modules. - An ``exceptions`` API chapter was added, documenting the new ``repoze.bfg.exceptions`` module.

2009-09-20- The way ``bfg_view`` declarations are scanned for has been modified.Chris McDonough
This should have no external effects. - An object implementing the ``IRenderer`` interface (and ``ITemplateRenderer`, which is a subclass of ``IRenderer``) must now accept an extra ``system`` argument in its ``__call__`` method implementation. Values computed by the system (as opposed to by the view) are passed by the system in the ``system`` parameter, which will always be a dictionary. Keys in the dictionary include: ``view`` (the view object that returned the value), ``renderer_name`` (the template name or simple name of the renderer), ``context`` (the context object passed to the view), and ``request`` (the request object passed to the view). Previously only ITemplateRenderers received system arguments as elements inside the main ``value`` dictionary.
