``repoze.bfg.configuration`` module began to attempt to import the
``repoze.bfg.chameleon_zpt`` and ``repoze.bfg.chameleon_text``
modules, and these cannot be used on non-CPython platforms. It now
tolerates startup time import failures for these modules, and only
raise an import error when a template from one of these packages is
actually used.

keyword argument: ``__provides__``. If this constructor argument is
provided, it should be an interface or a tuple of interfaces. The
resulting model will then provide these interfaces (they will be
attached to the constructed model via
``zope.interface.alsoProvides``).

or classes, and the ``for`` of first view registered was a
superclass of the second, the ``repoze.bfg` view machinery would
incorrectly associate the two views with the same "multiview".
Multiviews are meant to be collections of views that have *exactly*
the same for/request/viewname values, without taking inheritance
into account. Symptom: wrong view callable found even when you had
correctly specified a ``for_`` interface/class during view
configuration for one or both view configurations.

``request_type`` predicate caused a startup time failure when it was
encountered in imperative configuration or in a decorator (symptom:
``Type Error: Required specification must be a specification``).
This now works again, although ``request_method`` is a more modern
predicate.

purpose of isolating tests from one another may now begin to fail
due to lack of isolation between tests.
Here's why: In repoze.bfg 1.1 and prior, the registry returned by
``repoze.bfg.threadlocal.get_current_registry`` when no other
registry had been pushed on to the threadlocal stack was the
``zope.component.globalregistry.base`` global registry (aka the
result of ``zope.component.getGlobalSiteManager()``). In repoze.bfg
1.2+, however, the registry returned in this situation is the new
module-scope ``repoze.bfg.registry.global_registry`` object. The
``zope.testing.cleanup.cleanUp`` function clears the
``zope.component.globalregistry.base`` global registry
unconditionally. However, it does not know about the
``repoze.bfg.registry.global_registry`` object, so it does not clear
it.
If you use the ``zope.testing.cleanup.cleanUp`` function in the
``setUp`` of test cases in your unit test suite instead of using the
(more correct as of 1.1) ``repoze.bfg.testing.setUp``, you will need
to replace all calls to ``zope.testing.cleanup.cleanUp`` with a call
to ``repoze.bfg.testing.setUp``.
If replacing all calls to ``zope.testing.cleanup.cleanUp`` with a
call to ``repoze.bfg.testing.setUp`` is infeasible, you can put this
bit of code somewhere that is executed exactly **once** (*not* for
each test in a test suite; in the `` __init__.py`` of your
package would be a reasonable place)::
import zope.testing.cleanup
from repoze.bfg.testing import setUp
zope.testing.cleanup.addCleanUp(setUp)
- When there is no "current registry" in the
``repoze.bfg.threadlocal.manager`` threadlocal data structure (this
is the case when there is no "current request" or we're not in the
midst of a ``r.b.testing.setUp``-bounded unit test), the ``.get``
method of the manager returns a data structure containing a *global*
registry. In previous releases, this function returned the global
Zope "base" registry: the result of
``zope.component.getGlobalSiteManager``, which is an instance of the
``zope.component.registry.Component`` class. In this release,
however, the global registry returns a globally importable instance
of the ``repoze.bfg.registry.Registry`` class. This registry
instance can always be imported as
``repoze.bfg.registry.global_registry``.
Effectively, this means that when you call
``repoze.bfg.threadlocal.get_current_registry`` when no request or
``setUp`` bounded unit test is in effect, you will always get back
the global registry that lives in
``repoze.bfg.registry.global_registry``. It also means that
:mod:`repoze.bfg` APIs that *call* ``get_current_registry`` will use
this registry.
This change was made because :mod:`repoze.bfg` now expects the
registry it uses to have a slightly different API than a bare
instance of ``zope.component.registry.Components``.
