It also documents backwards +incompatibilities between the two versions and deprecations added to +:app:`Pyramid` 1.5, as well as software dependency changes and notable +documentation additions. + +Feature Additions +----------------- + +The feature additions in Pyramid 1.5 follow. + +- Add ``pdistreport`` script, which prints the Python version in use, the + Pyramid version in use, and the version number and location of all Python + distributions currently installed. + +- Add the ability to invert the result of any view, route, or subscriber + predicate value using the ``not_`` class. For example: + + .. code-block:: python + + from pyramid.config import not_ + + @view_config(route_name='myroute', request_method=not_('POST')) + def myview(request): ... + + The above example will ensure that the view is called if the request method + is not POST, at least if no other view is more specific. + + The :class:`pyramid.config.not_` class can be used against any value that is + a predicate value passed in any of these contexts: + + - :meth:`pyramid.config.Configurator.add_view` + + - :meth:`pyramid.config.Configurator.add_route` + + - :meth:`pyramid.config.Configurator.add_subscriber` + + - :meth:`pyramid.view.view_config` + + - :meth:`pyramid.events.subscriber` + +- View lookup will now search for valid views based on the inheritance + hierarchy of the context. It tries to find views based on the most specific + context first, and upon predicate failure, will move up the inheritance chain + to test views found by the super-type of the context. In the past, only the + most specific type containing views would be checked and if no matching view + could be found then a PredicateMismatch would be raised. Now predicate + mismatches don't hide valid views registered on super-types. Here's an + example that now works: + + .. code-block:: python + + class IResource(Interface): + + ... + + @view_config(context=IResource) + def get(context, request): + + ... + + @view_config(context=IResource, request_method='POST') + def post(context, request): + + ... + + @view_config(context=IResource, request_method='DELETE') + def delete(context, request): + + ... + + @implementor(IResource) + class MyResource: + + ... + + @view_config(context=MyResource, request_method='POST') + def override_post(context, request): + + ... + + Previously the override_post view registration would hide the get + and delete views in the context of MyResource -- leading to a + predicate mismatch error when trying to use GET or DELETE + methods. Now the views are found and no predicate mismatch is + raised. + See https://github.com/Pylons/pyramid/pull/786 and + https://github.com/Pylons/pyramid/pull/1004 and + https://github.com/Pylons/pyramid/pull/1046 + +- ``scripts/prequest.py`` (aka the ``prequest`` console script): added support + for submitting ``PUT`` and ``PATCH`` requests. See + https://github.com/Pylons/pyramid/pull/1033. add support for submitting + ``OPTIONS`` and ``PROPFIND`` requests, and allow users to specify basic + authentication credentials in the request via a ``--login`` argument to the + script. See https://github.com/Pylons/pyramid/pull/1039. + +- :class:`pyramid.authorization.ACLAuthorizationPolicy` supports ``__acl__`` as + a callable. This removes the ambiguity between the potential + ``AttributeError`` that would be raised on the ``context`` when the property + was not defined and the ``AttributeError`` that could be raised from any + user-defined code within a dynamic property. It is recommended to define a + dynamic ACL as a callable to avoid this ambiguity. See + https://github.com/Pylons/pyramid/issues/735. + +- Allow a protocol-relative URL (e.g. ``//example.com/images``) to be passed to + :meth:`pyramid.config.Configurator.add_static_view`. This allows + externally-hosted static URLs to be generated based on the current protocol. + +- The :class:`pyramid.authentication.AuthTktAuthenticationPolicy` has a new + ``parent_domain`` option to set the authentication cookie as a wildcard + cookie on the parent domain. This is useful if you have multiple sites + sharing the same domain. It also now supports IPv6 addresses when using + the ``include_ip=True`` option. This is possibly incompatible with + alternative ``auth_tkt`` implementations, as the specification does not + define how to properly handle IPv6. See + https://github.com/Pylons/pyramid/issues/831. + +- Make it possible to use variable arguments via + :func:`pyramid.paster.get_appsettings`. This also allowed the generated + ``initialize_db`` script from the ``alchemy`` scaffold to grow support for + options in the form ``a=1 b=2`` so you can fill in values in a parameterized + ``.ini`` file, e.g. ``initialize_myapp_db etc/development.ini a=1 b=2``. See + https://github.com/Pylons/pyramid/pull/911 + +- The ``request.session.check_csrf_token()`` method and the ``check_csrf`` view + predicate now take into account the value of the HTTP header named + ``X-CSRF-Token`` (as well as the ``csrf_token`` form parameter, which they + always did). The header is tried when the form parameter does not exist. + +Backwards Incompatibilities +--------------------------- + +This release has no known backwards incompatibilities with Pyramid 1.4.X. + +Deprecations +------------ + +This release has no new deprecations as compared to Pyramid 1.4.X. + + +Documentation Enhancements +-------------------------- + +Many documentation enhancements have been added, but we did not track them as +they were added. + +Dependency Changes +------------------ + +No dependency changes from Pyramid 1.4.X were made in Pyramid 1.5. + |
