Description: Pyramid
        =======
        
        Pyramid is a small, fast, down-to-earth, open source Python web application
        development framework. It makes real-world web application development and
        deployment more fun, more predictable, and more productive.
        
        Pyramid is the newest web framework produced by the `Pylons Project
        <http://pylonsproject.org/>`_.
        
        Pyramid was previously known as `repoze.bfg <http://bfg.repoze.org>`_.

        1.2a1 (2011-08-24)
        ==================
        
        Features
        --------
        
        - The ``[pshell]`` section in an ini configuration file now treats a
        ``setup`` key as a dotted name that points to a callable that is passed the
        bootstrap environment.  It can mutate the environment as necessary for
        great justice.
        
        - A new configuration setting named ``pyramid.includes`` is now available.
        It is described in the "Environment Variables and ``.ini`` Files Settings"
        narrative documentation chapter.
        
        - Added a ``route_prefix`` argument to the
        ``pyramid.config.Configurator.include`` method.  This argument allows you
        to compose URL dispatch applications together.  See the section entitled
        "Using a Route Prefix to Compose Applications" in the "URL Dispatch"
        narrative documentation chapter.
        
        - Added a ``pyramid.security.NO_PERMISSION_REQUIRED`` constant for use in
        ``permission=`` statements to view configuration.  This constant has a
        value of the string ``__no_permission_required__``.  This string value was
        previously referred to in documentation; now the documentation uses the
        constant.
        
        - Added a decorator-based way to configure a response adapter:
        ``pyramid.response.response_adapter``.  This decorator has the same use as
        ``pyramid.config.Configurator.add_response_adapter`` but it's declarative.
        
        - The ``pyramid.events.BeforeRender`` event now has an attribute named
        ``rendering_val``.  This can be used to introspect the value returned by a
        view in a BeforeRender subscriber.
        
        - New configurator directive: ``pyramid.config.Configurator.add_tween``.
        This directive adds a "tween".  A "tween" is used to wrap the Pyramid
        router's primary request handling function.  This is a feature may be used
        by Pyramid framework extensions, to provide, for example, view timing
        support and as a convenient place to hang bookkeeping code.
        
        Tweens are further described in the narrative docs section in the Hooks
        chapter, named "Registering Tweens".
        
        - New paster command ``paster ptweens``, which prints the current "tween"
        configuration for an application.  See the section entitled "Displaying
        Tweens" in the Command-Line Pyramid chapter of the narrative documentation
        for more info.
        
        - The Pyramid debug logger now uses the standard logging configuration
        (usually set up by Paste as part of startup).  This means that output from
        e.g. ``debug_notfound``, ``debug_authorization``, etc. will go to the
        normal logging channels.  The logger name of the debug logger will be the
        package name of the *caller* of the Configurator's constructor.
        
        - A new attribute is available on request objects: ``exc_info``.  Its value
        will be ``None`` until an exception is caught by the Pyramid router, after
        which it will be the result of ``sys.exc_info()``.
        
        - ``pyramid.testing.DummyRequest`` now implements the
        ``add_finished_callback`` and ``add_response_callback`` methods.
        
        - New methods of the ``pyramid.config.Configurator`` class:
        ``set_authentication_policy`` and ``set_authorization_policy``.  These are
        meant to be consumed mostly by add-on authors.
        
        - New Configurator method: ``set_root_factory``.
        
        - Pyramid no longer eagerly commits some default configuration statements at
        Configurator construction time, which permits values passed in as
        constructor arguments (e.g. ``authentication_policy`` and
        ``authorization_policy``) to override the same settings obtained via an
        "include".
        
        - Better Mako rendering exceptions via
        ``pyramid.mako_templating.MakoRenderingException``
        
        - New request methods: ``current_route_url``, ``current_route_path``, and
        ``static_path``.
        
        - New functions in ``pyramid.url``: ``current_route_path`` and
        ``static_path``.
        
        - The ``pyramid.request.Request.static_url`` API (and its brethren
        ``pyramid.request.Request.static_path``, ``pyramid.url.static_url``, and
        ``pyramid.url.static_path``) now accept an asbolute filename as a "path"
        argument.  This will generate a URL to an asset as long as the filename is
        in a directory which was previously registered as a static view.
        Previously, trying to generate a URL to an asset using an absolute file
        path would raise a ValueError.
        
        - The ``RemoteUserAuthenticationPolicy ``, ``AuthTktAuthenticationPolicy``,
        and ``SessionAuthenticationPolicy`` constructors now accept an additional
        keyword argument named ``debug``.  By default, this keyword argument is
        ``False``.  When it is ``True``, debug information will be sent to the
        Pyramid debug logger (usually on stderr) when the ``authenticated_userid``
        or ``effective_principals`` method is called on any of these policies.  The
        output produced can be useful when trying to diagnose
        authentication-related problems.
        
        - New view predicate: ``match_param``.  Example: a view added via
        ``config.add_view(aview, match_param='action=edit')`` will be called only
        when the ``request.matchdict`` has a value inside it named ``action`` with
        a value of ``edit``.
        
        Internal
        --------
        
        - The Pyramid "exception view" machinery is now implemented as a "tween"
        (``pyramid.tweens.excview_tween_factory``).
        
        - WSGIHTTPException (HTTPFound, HTTPNotFound, etc) now has a new API named
        "prepare" which renders the body and content type when it is provided with
        a WSGI environ.  Required for debug toolbar.
        
        - Once ``__call__`` or ``prepare`` is called on a WSGIHTTPException, the body
        will be set, and subsequent calls to ``__call__`` will always return the
        same body.  Delete the body attribute to rerender the exception body.
        
        - Previously the ``pyramid.events.BeforeRender`` event *wrapped* a dictionary
        (it addressed it as its ``_system`` attribute).  Now it *is* a dictionary
        (it inherits from ``dict``), and it's the value that is passed to templates
        as a top-level dictionary.
        
        - The ``route_url``, ``route_path``, ``resource_url``, ``static_url``, and
        ``current_route_url`` functions in the ``pyramid.url`` package now delegate
        to a method on the request they've been passed, instead of the other way
        around.  The pyramid.request.Request object now inherits from a mixin named
        pyramid.url.URLMethodsMixin to make this possible, and all url/path
        generation logic is embedded in this mixin.
        
        - Refactor ``pyramid.config`` into a package.
        
        - Removed the ``_set_security_policies`` method of the Configurator.
        
        - Moved the ``StaticURLInfo`` class from ``pyramid.static`` to
        ``pyramid.config.views``.
        
        - Move the ``Settings`` class from ``pyramid.settings`` to
        ``pyramid.config.settings``.
        
        - Move the ``OverrideProvider``, ``PackageOverrides``, ``DirectoryOverride``,
        and ``FileOverride`` classes from ``pyramid.asset`` to
        ``pyramid.config.assets``.
        
        Deprecations
        ------------
        
        - All Pyramid-related deployment settings (e.g. ``debug_all``,
        ``debug_notfound``) are now meant to be prefixed with the prefix
        ``pyramid.``.  For example: ``debug_all`` -> ``pyramid.debug_all``.  The
        old non-prefixed settings will continue to work indefinitely but supplying
        them may eventually print a deprecation warning.  All scaffolds and
        tutorials have been changed to use prefixed settings.
        
        - The ``settings`` dictionary now raises a deprecation warning when you
        attempt to access its values via ``__getattr__`` instead of
        via ``__getitem__``.
        
        Backwards Incompatibilities
        ---------------------------
        
        - If a string is passed as the ``debug_logger`` parameter to a Configurator,
        that string is considered to be the name of a global Python logger rather
        than a dotted name to an instance of a logger.
        
        - The ``pyramid.config.Configurator.include`` method now accepts only a
        single ``callable`` argument (a sequence of callables used to be
        permitted).  If you are passing more than one ``callable`` to
        ``pyramid.config.Configurator.include``, it will break.  You now must now
        instead make a separate call to the method for each callable.  This change
        was introduced to support the ``route_prefix`` feature of include.
        
        - It may be necessary to more strictly order configuration route and view
        statements when using an "autocommitting" Configurator.  In the past, it
        was possible to add a view which named a route name before adding a route
        with that name when you used an autocommitting configurator.  For example::
        
        config = Configurator(autocommit=True)
        config.add_view('my.pkg.someview', route_name='foo')
        config.add_route('foo', '/foo')
        
        The above will raise an exception when the view attempts to add itself.
        Now you must add the route before adding the view::
        
        config = Configurator(autocommit=True)
        config.add_route('foo', '/foo')
        config.add_view('my.pkg.someview', route_name='foo')
        
        This won't effect "normal" users, only people who have legacy BFG codebases
        that used an autommitting configurator and possibly tests that use the
        configurator API (the configurator returned by ``pyramid.testing.setUp`` is
        an autocommitting configurator).  The right way to get around this is to
        use a non-autocommitting configurator (the default), which does not have
        these directive ordering requirements.
        
        - The ``pyramid.config.Configurator.add_route`` directive no longer returns a
        route object.  This change was required to make route vs. view
        configuration processing work properly.
        
        Documentation
        -------------
        
        - Narrative and API documentation which used the ``route_url``,
        ``route_path``, ``resource_url``, ``static_url``, and ``current_route_url``
        functions in the ``pyramid.url`` package have now been changed to use
        eponymous methods of the request instead.
        
        - Added a section entitled "Using a Route Prefix to Compose Applications" to
        the "URL Dispatch" narrative documentation chapter.
        
        - Added a new module to the API docs: ``pyramid.tweens``.
        
        - Added a "Registering Tweens" section to the "Hooks" narrative chapter.
        
        - Added a "Displaying Tweens" section to the "Command-Line Pyramid" narrative
        chapter.
        
        - Added documentation for the ``pyramid.tweens`` and ``pyramid.includes``
        configuration settings to the "Environment Variables and ``.ini`` Files
        Settings" chapter.
        
        - Added a Logging chapter to the narrative docs (based on the Pylons logging
        docs, thanks Phil).
        
        - Added a Paste chapter to the narrative docs (moved content from the Project
        chapter).
        
        - Added the ``pyramid.interfaces.IDict`` interface representing the methods
        of a dictionary, for documentation purposes only (IMultiDict and
        IBeforeRender inherit from it).
        
        - All tutorials now use - The ``route_url``, ``route_path``,
        ``resource_url``, ``static_url``, and ``current_route_url`` methods of the
        request rather than the function variants imported from ``pyramid.url``.
        
        - The ZODB wiki tutorial now uses the ``pyramid_zodbconn`` package rather
        than the ``repoze.zodbconn`` package to provide ZODB integration.
        
        Dependency Changes
        ------------------
        
        - Pyramid now relies on PasteScript >= 1.7.4.  This version contains a
        feature important for allowing flexible logging configuration.
        
        Scaffolds
        ----------
        
        - All scaffolds now use the ``pyramid_tm`` package rather than the
        ``repoze.tm2`` middleware to manage transaction management.
        
        - The ZODB scaffold now uses the ``pyramid_zodbconn`` package rather than the
        ``repoze.zodbconn`` package to provide ZODB integration.
        
        - All scaffolds now use the ``pyramid_debugtoolbar`` package rather than the
        ``WebError`` package to provide interactive debugging features.
        
        - Projects created via a scaffold no longer depend on the ``WebError``
        package at all; configuration in the ``production.ini`` file which used to
        require its ``error_catcher`` middleware has been removed.  Configuring
        error catching / email sending is now the domain of the ``pyramid_exclog``
        package (see https://docs.pylonsproject.org/projects/pyramid_exclog/dev/).
        
        Bug Fixes
        ---------
        
        - Fixed an issue with the default renderer not working at certain times.  See
