- 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``.

This URL is a subclass of the built-in Python exception named
``UnicodeDecodeError``.
- When decoding a URL segment to Unicode fails, the exception raised
is now ``repoze.bfg.exceptions.URLDecodeError`` instead of
``UnicodeDecodeError``. This makes it possible to register an
exception view invoked specifically when ``repoze.bfg`` cannot
decode a URL.

``repoze.bfg.configuration.Configurator.add_static_view``. Before
1.3a4, view names that contained a slash were supported as route
prefixes. 1.3a4 broke this by trying to treat them as full URLs.

``_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.

dispatch route (each of the predicate functions fed to the
``custom_predicates`` argument of
``repoze.bfg.configuration.Configurator.add_route``) has always
required a 2-positional argument signature, e.g. ``(context,
request)``. Before this release, the ``context`` argument was
always ``None``.
As of this release, the first argument passed to a predicate is now
a dictionary conventionally named ``info`` consisting of ``match``,
``route``, and ``mapper``. ``match`` is a dictionary: it represents
the arguments matched in the URL by the route. ``route`` is an
object representing the route that matched. ``mapper`` is the url
dispatch route mapper object.
This is useful when predicates need access to the route match. For
example::
def any_of(segment_name, *args):
def predicate(info, request):
if info['match'][segment_name] in args:
return True
num_one_two_or_three = any_of('num, 'one', 'two', 'three')
add_route('/:num', custom_predicates=(num_one_two_or_three,))

============
Paster Templates
----------------
- The ``bfg_alchemy`` and ``bfg_routesalchemy`` templates no longer
register a ``handle_teardown`` event listener which calls
``DBSession.remove``. This was found by Chris Withers to be
unnecessary.
Documentation
-------------
- The "bfgwiki2" (URL dispatch wiki) tutorial code and documentation
was changed to remove the ``handle_teardown`` event listener which
calls ``DBSession.remove``.
- Any mention of the ``handle_teardown`` event listener as used by the
paster templates was removed from the URL Dispatch narrative chapter.

--------
- A locale negotiator no longer needs to be registered explicitly. The
default locale negotiator at
``repoze.bfg.i18n.default_locale_negotiator`` is now used
unconditionally as... um, the default locale negotiator.
- The default locale negotiator has become more complex.
* First, the negotiator looks for the ``_LOCALE_`` attribute of
the request object (possibly set by an :term:`event listener`).
* Then it looks for the ``request.params['_LOCALE_']`` value.
* Then it looks for the ``request.cookies['_LOCALE_']`` value.
Backwards Incompatibilities
---------------------------
- The default locale negotiator now looks for the parameter named
``_LOCALE_`` rather than a parameter named ``locale`` in
``request.params``.
Behavior Changes
----------------
- A locale negotiator may now return ``None``, signifying that the
default locale should be used.
Documentation
-------------
- Documentation concerning locale negotiation in the
Internationalizationa and Localization chapter was updated.

be used to generate a BFG view callable from a user-supplied
function, instance, or class. This useful for external framework and
plugin authors wishing to wrap callables supplied by their users
which follow the same calling conventions and response conventions
as objects that can be supplied directly to BFG as a view callable.
See the ``derive_view`` method in the
``repoze.bfg.configuration.Configurator`` docs.

for all Chameleon BFG templates by setting a BFG-related Paster
``.ini`` file setting named ``debug_templates``. The exceptions
raised by Chameleon templates when a rendering fails are sometimes
less than helpful. ``debug_templates`` allows you to configure your
application development environment so that exceptions generated by
Chameleon during template compilation and execution will contain
more helpful debugging information. This mode is on by default in
all new projects.

<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.
