``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).

function populates a component registry from a ZCML file for testing
purposes.
|
|
--------
- Add ``setUp`` and ``tearDown`` functions to the
``repoze.bfg.testing`` module. Using ``setUp`` in a test setup and
``tearDown`` in a test teardown is now the recommended way to do
component registry setup and teardown. Previously, it was
recommended that a single function named
``repoze.bfg.testing.cleanUp`` be called in both the test setup and
tear down. ``repoze.bfg.testing.cleanUp`` still exists (and will
exist "forever" due to its widespread use); it is now just an alias
for ``repoze.bfg.testing.setUp`` and is nominally deprecated.
- The BFG component registry is now available in view and event
subscriber code as an attribute of the request
ie. ``request.registry``. This fact is currently undocumented
except for this note, because BFG developers never need to interact
with the registry directly anywhere else.
- The BFG component registry now inherits from ``dict``, meaning that
it can optionally be used as a simple dictionary. *Component*
registrations performed against it via e.g. ``registerUtility``,
``registerAdapter``, and similar API methods are kept in a
completely separate namespace than its dict members, so using the
its component API methods won't effect the keys and values in the
dictionary namespace. Likewise, though the component registry
"happens to be" a dictionary, use of mutating dictionary methods
such as ``__setitem__`` will have no influence on any component
registrations made against it. In other words, the registry object
you obtain via e.g. ``repoze.bfg.threadlocal.get_current_registry``
or ``request.registry`` happens to be both a component registry and
a dictionary, but using its component-registry API won't impact data
added to it via its dictionary API and vice versa. This is a
forward compatibility move based on the goals of "marco".
Documentation
-------------
- Various tutorial test modules updated to use
``repoze.bfg.testing.setUp`` and ``repoze.bfg.testing.tearDown``
methods in order to encourage this as best practice going forward.
Backwards Incompatibilities
---------------------------
- Importing ``getSiteManager`` and ``get_registry`` from
``repoze.bfg.registry`` is no longer supported. These imports were
deprecated in repoze.bfg 1.0. Import of ``getSiteManager`` should
be done as ``from zope.component import getSiteManager``. Import of
``get_registry`` should be done as ``from repoze.bfg.threadlocal
import get_current_registry``. This was done to prevent a circular
import dependency.
- Code bases which alternately invoke both
``zope.testing.cleanup.cleanUp`` and ``repoze.bfg.testing.cleanUp``
(treating them equivalently, using them interchangeably) in the
setUp/tearDown of unit tests will begin to experience test failures
due to lack of test isolation. The "right" mechanism is
``repoze.bfg.testing.cleanUp`` (or the combination of
``repoze.bfg.testing.setUp`` and
``repoze.bfg.testing.tearDown``). but a good number of legacy
codebases will use ``zope.testing.cleanup.cleanUp`` instead. We
support ``zope.testing.cleanup.cleanUp`` but not in combination with
``repoze.bfg.testing.cleanUp`` in the same codebase. You should use
one or the other test cleanup function in a single codebase, but not
both.
Internal
--------
- Created new ``repoze.bfg.configuration`` module which assumes
responsibilities previously held by the ``repoze.bfg.registry`` and
``repoze.bfg.router`` modules (avoid a circular import dependency).
- The result of the ``zope.component.getSiteManager`` function in unit
tests set up with ``repoze.bfg.testing.cleanUp`` or
``repoze.bfg.testing.setUp`` will be an instance of
``repoze.bfg.registry.Registry`` instead of the global
``zope.component.globalregistry.base`` registry. This also means
that the threadlocal ZCA API functions such as ``getAdapter`` and
``getUtility`` as well as internal BFG machinery (such as
``model_url`` and ``route_url``) will consult this registry within
unit tests. This is a forward compatibility move based on the goals
of "marco".
- Removed ``repoze.bfg.testing.addCleanUp`` function and associated
module-scope globals. This was never an API.
