2009-05-30- Add an AuthTktAuthenticationPolicy. This policy retrievesChris McDonough
credentials from an auth_tkt cookie managed by the application itself (instead of relying on an upstream data source for authentication data). See the Security API chapter of the documentation for more info. - Allow RemoteUserAuthenticationPolicy and RepozeWho1AuthenticationPolicy to accept various constructor arguments. See the Security API chapter of the documentation for more info.
2009-05-28- Add a ``get_app`` API functions to the ``paster`` module. ThisChris McDonough
obtains a WSGI application from a config file given a config file name and a section name. See the ``repoze.bfg.paster`` API docs for more information. - Add a new module named ``scripting``. It contains a ``get_root`` API function, which, provided a Router instance, returns a traversal root object and a "closer". See the ``repoze.bfg.scripting`` API docs for more info.

-------- - Added a ``traverse`` function to the ``repoze.bfg.traversal`` module. This function may be used to retrieve certain values computed during path resolution. See the Traversal API chapter of the documentation for more information about this function. Deprecations ------------ - Internal: ``ITraverser`` callables should now return a dictionary rather than a tuple. Up until 0.7.0, all ITraversers were assumed to return a 3-tuple. In 0.7.1, ITraversers were assumed to return a 6-tuple. As (by evidence) it's likely we'll need to add further information to the return value of an ITraverser callable, 0.8 assumes that an ITraverser return a dictionary with certain elements in it. See the ``repoze.bfg.interfaces.ITraverser`` interface for the list of keys that should be present in the dictionary. ``ITraversers`` which return tuples will still work, although a deprecation warning will be issued. Backwards Incompatibilities --------------------------- - If your code used the ITraverser interface directly (not via an API function such as ``find_model``) via an adapter lookup, you'll need to change your code to expect a dictionary rather than a 3- or 6-tuple if your code ever gets return values from the default ModelGraphTraverser or RoutesModelTraverser adapters.
2009-05-16This feature was removed.Chris McDonough
2009-05-14- Added API docs for the ``repoze.bfg.testing`` methodsChris McDonough
``registerAdapter``, ``registerUtiity``, ``registerSubscriber``, and ``cleanUp``. - Added glossary entry for "root factory".
2009-05-06FeaturesChris McDonough
-------- - Two new security policies were added: RemoteUserInheritingACLSecurityPolicy and WhoInheritingACLSecurityPolicy. These are security policies which take into account *all* ACLs defined in the lineage of a context rather than stopping at the first ACL found in a lineage. See the "Security" chapter of the API documentation for more information. - The API and narrative documentation dealing with security was changed to introduce the new "inheriting" security policy variants. - Added glossary entry for "lineage". Deprecations ------------ - The security policy previously named ``RepozeWhoIdentityACLSecurityPolicy`` now has the slightly saner name of ``WhoACLSecurityPolicy``. A deprecation warning is emitted when this policy is imported under the "old" name; usually this is due to its use in ZCML within your application. If you're getting this deprecation warning, change your ZCML to use the new name, e.g. change:: <utility provides="repoze.bfg.interfaces.ISecurityPolicy" factory="repoze.bfg.security.RepozeWhoIdentityACLSecurityPolicy" /> To:: <utility provides="repoze.bfg.interfaces.ISecurityPolicy" factory="repoze.bfg.security.WhoACLSecurityPolicy" />

2009-04-16- The interface for ``repoze.bfg.interfaces.ITraverser`` and theChris McDonough
built-in implementations that implement the interface (``repoze.bfg.traversal.ModelGraphTraverser``, and ``repoze.bfg.urldispatch.RoutesModelTraverser``) now expect the ``__call__`` method of an ITraverser to return 3 additional arguments: ``traversed``, ``virtual_root``, and ``virtual_root_path`` (the old contract was that the ``__call__`` method of an ITraverser returned; three arguments, the contract new is that it returns six). ``traversed`` will be a sequence of Unicode names that were traversed (including the virtual root path, if any) or ``None`` if no traversal was performed, ``virtual_root`` will be a model object representing the virtual root (or the physical root if traversal was not performed), and ``virtual_root_path`` will be a sequence representing the virtual root path (a sequence of Unicode names) or ``None`` if traversal was not performed. Six arguments are now returned from BFG ITraversers. They are returned in this order: ``context``, ``view_name``, ``subpath``, ``traversed``, ``virtual_root``, and ``virtual_root_path``. Places in the BFG code which called an ITraverser continue to accept a 3-argument return value, although BFG will generate and log a warning when one is encountered. - The request object now has the following attributes: ``traversed`` (the sequence of names traversed or ``None`` if traversal was not performed), ``virtual_root`` (the model object representing the virtual root, including the virtual root path if any), and ``virtual_root_path`` (the seuquence of names representing the virtual root path or ``None`` if traversal was not performed). - A new decorator named ``wsgiapp2`` was added to the ``repoze.bfg.wsgi`` module. This decorator performs the same function as ``repoze.bfg.wsgi.wsgiapp`` except it fixes up the ``SCRIPT_NAME``, and ``PATH_INFO`` environment values before invoking the WSGI subapplication. - The ``repoze.bfg.testing.DummyRequest`` object now has default attributes for ``traversed``, ``virtual_root``, and ``virtual_root_path``. - The RoutesModelTraverser now behaves more like the Routes "RoutesMiddleware" object when an element in the match dict is named ``path_info`` (usually when there's a pattern like ``http://foo/*path_info``). When this is the case, the ``PATH_INFO`` environment variable is set to the value in the match dict, and the ``SCRIPT_NAME`` is appended to with the prefix of the original ``PATH_INFO`` not including the value of the new variable. - The notfound debug now shows the traversed path, the virtual root, and the virtual root path too.

2009-02-06Revert my decision to make ``model_path`` return a tuple; itChris McDonough
now still returns a string; albeit a quoted one. An additional API (model_path_tuple) now also exists which can be used to get a model path as a tuple. - The ``repoze.bfg.traversal.model_path`` API now returns a *quoted* string rather than a string represented by series of unquoted elements joined via ``/`` characters. Previously it returned a string or unicode object representing the model path, with each segment name in the path joined together via ``/`` characters, e.g. ``/foo /bar``. Now it returns a string, where each segment is a UTF-8 encoded and URL-quoted element e.g. ``/foo%20/bar``. This change was (as discussed briefly on the repoze-dev maillist) necessary to accomodate model objects which themselves have ``__name__`` attributes that contain the ``/`` character. For people that have no models that have high-order Unicode ``__name__`` attributes or ``__name__`` attributes with values that require URL-quoting with in their model graphs, this won't cause any issue. However, if you have code that currently expects ``model_path`` to return an unquoted string, or you have an existing application with data generated via the old method, and you're too lazy to change anything, you may wish replace the BFG-imported ``model_path`` in your code with this function (this is the code of the "old" ``model_path`` implementation):: from repoze.bfg.location import lineage def i_am_too_lazy_to_move_to_the_new_model_path(model, *elements): rpath = [] for location in lineage(model): if location.__name__: rpath.append(location.__name__) path = '/' + '/'.join(reversed(rpath)) if elements: suffix = '/'.join(elements) path = '/'.join([path, suffix]) return path - The ``repoze.bfg.traversal.find_model`` API no longer implicitly converts unicode representations of a full path passed to it as a Unicode object into a UTF-8 string. Callers should either use prequoted path strings returned by ``repoze.bfg.traversal.model_path``, or tuple values returned by the result of ``repoze.bfg.traversal.model_path_tuple`` or they should use the guidelines about passing a string ``path`` argument described in the ``find_model`` API documentation. - Each argument contained in ``elements`` passed to ``repoze.bfg.traversal.model_path`` will now have any ``/`` characters contained within quoted to ``%2F`` in the returned string. Previously, ``/`` characters in elements were left unquoted (a bug). - A ``repoze.bfg.traversal.model_path_tuple`` API was added. This API is an alternative to ``model_path`` (which returns a string); ``model_path_tuple`` returns a model path as a tuple (much like Zope's ``getPhysicalPath``). - A ``repoze.bfg.traversal.quote_path_segment`` API was added. This API will quote an individual path segment (string or unicode object). See the ``repoze.bfg.traversal`` API documentation for more information.
2009-01-27FeaturesChris McDonough
-------- - The ``repoze.bfg.url.model_url`` API now works against contexts derived from Routes URL dispatch (``Routes.util.url_for`` is called under the hood). - "Virtual root" support for traversal-based applications has been added. Virtual root support is useful when you'd like to host some model in a :mod:`repoze.bfg` model graph as an application under a URL pathname that does not include the model path itself. For more information, see the (new) "Virtual Hosting" chapter in the documentation. - A ``repoze.bfg.traversal.virtual_root`` API has been added. When called, it returns the virtual root object (or the physical root object if no virtual root has been specified). Implementation Changes ---------------------- - ``repoze.bfg.traversal.RoutesModelTraverser`` has been moved to ``repoze.bfg.urldispatch``. - ``model_url`` URL generation is now performed via an adapter lookup based on the context and the request. - ZCML which registers two adapters for the ``IContextURL`` interface has been added to the configure.zcml in ``repoze.bfg.includes``.
2009-01-26- Added a ``traversal_path`` API to the traversal module; see theChris McDonough
"traversal" API chapter in the docs. This was a function previously known as ``split_path`` that was not an API but people were using it anyway. Unlike ``split_path`` it now returns a tuple instead of a list (as its values are cached).

2009-01-12- An interface specific to the HTTP verb (GET/PUT/POST/DELETE/HEAD) isChris McDonough
attached to each request object on ingress. The HTTP-verb-related interfaces are defined in ``repoze.bfg.interfaces`` and are ``IGETRequest``, ``IPOSTRequest``, ``IPUTRequest``, ``IDELETERequest`` and ``IHEADRequest``. These interfaces can be specified as the ``request_type`` attribute of a bfg view declaration. A view naming a specific HTTP-verb-matching interface will be found only if the view is defined with a request_type that matches the HTTP verb in the incoming request. The more general ``IRequest`` interface can be used as the request_type to catch all requests (and this is indeed the default). All requests implement ``IRequest``. The HTTP-verb-matching idea was pioneered by `repoze.bfg.restrequest <http://pypi.python.org/pypi/repoze.bfg.restrequest/1.0.1>`_ . That package is no longer required, but still functions fine.
2009-01-07- Add a method named ``assert_`` to the DummyTemplateRenderer. ThisChris McDonough
method accepts keyword arguments. Each key/value pair in the keyword arguments causes an assertion to be made that the renderer received this key with a value equal to the asserted value. - Projects generated by the paster templates now use the ``DummyTemplateRenderer.assert_`` method in their view tests.
2009-01-06 - A ``static`` helper class was added to the ``repoze.bfg.views``Chris McDonough
module. Instances of this class are willing to act as BFG views which return static resources using files on disk. See the :mod:`repoze.bfg.view` docs for more info.
2009-01-05 New ModulesChris McDonough
- A new module ``repoze.bfg.url`` has been added. It contains the ``model_url`` API (moved from ``repoze.bfg.traversal``) and an implementation of ``urlencode`` (like Python's ``urllib.urlencode``) which can handle Unicode keys and values in parameters to the ``query`` argument. Deprecations - The ``model_url`` function has been moved from ``repoze.bfg.traversal`` into ``repoze.bfg.url``. It can still be imported from ``repoze.bfg.traversal`` but an import from ``repoze.bfg.traversal`` will emit a DeprecationWarning. Features - The ``repoze.bfg.url.model_url`` API (nee' ``repoze.bfg.traversal.model_url``) now accepts and honors a keyword argument named ``query``. The value of this argument will be used to compose a query string, which will be attached to the generated URL before it is returned. See the API docs (in the docs directory or `on the web <http://static.repoze.org/bfgdocs>`_) for more information.

2008-11-07 FeaturesChris McDonough
- Added a ``repoze.bfg.testing`` module to attempt to make it slightly easier to write unittest-based automated tests of BFG applications. Information about this class is in the documentation. - The default template renderer now supports testing better by looking for ``ITestingTemplateRenderer`` using a relative pathname. This is exposed indirectly through the API named ``registerTemplate`` in ``repoze.bfg.testing``. Deprecations - The names ``repoze.bfg.interfaces.ITemplate`` , ``repoze.bfg.interfaces.ITemplateFactory`` and ``repoze.bfg.interfaces.INodeTemplate`` have been deprecated. These should now be imported as ``repoze.bfg.interfaces.ITemplateRenderer`` and ``repoze.bfg.interfaces.ITemplateRendererFactory``, and ``INodeTemplateRenderer`` respectively. - The name ``repoze.bfg.chameleon_zpt.ZPTTemplateFactory`` is deprecated. Use ``repoze.bfg.chameleon_zpt.ZPTTemplateRenderer``. - The name ``repoze.bfg.chameleon_genshi.GenshiTemplateFactory`` is deprecated. Use ``repoze.bfg.chameleon_genshi.GenshiTemplateRenderer``. - The name ``repoze.bfg.xslt.XSLTemplateFactory`` is deprecated. Use ``repoze.bfg.xslt.XSLTemplateRenderer``.
2008-11-02 FeaturesChris McDonough
- The ``BFG_DEBUG_AUTHORIZATION`` envvar and the ``debug_authorization`` config file value now only imply debugging of view-invoked security checks. Previously, information was printed for every call to ``has_permission`` as well, which made output confusing. To debug ``has_permission`` checks and other manual permission checks, use the debugger and print statements in your own code. - Authorization debugging info is now only present in the HTTP response body oif ``debug_authorization`` is true. - The format of authorization debug messages was improved. - A new ``BFG_DEBUG_NOTFOUND`` envvar was added and a symmetric ``debug_notfound`` config file value was added. When either is true, and a NotFound response is returned by the BFG router (because a view could not be found), debugging information is printed to stderr. When this value is set true, the body of HTTPNotFound responses will also contain the same debugging information. - ``Allowed`` and ``Denied`` responses from the security machinery are now specialized into two types: ACL types, and non-ACL types. The ACL-related responses are instances of ``repoze.bfg.security.ACLAllowed`` and ``repoze.bfg.security.ACLDenied``. The non-ACL-related responses are ``repoze.bfg.security.Allowed`` and ``repoze.bfg.security.Denied``. The allowed-type responses continue to evaluate equal to things that themselves evaluate equal to the ``True`` boolean, while the denied-type responses continue to evaluate equal to things that themselves evaluate equal to the ``False`` boolean. The only difference between the two types is the information attached to them for debugging purposes. - Added a new ``BFG_DEBUG_ALL`` envvar and a symmetric ``debug_all`` config file value. When either is true, all other debug-related flags are set true unconditionally (e.g. ``debug_notfound`` and ``debug_authorization``). Documentation - Added info about debug flag changes. - Added a section to the security chapter named "Debugging Imperative Authorization Failures" (for e.g. ``has_permssion``).
2008-09-28 FeaturesChris McDonough
- A ``repoze.bfg.location`` API module was added. Backwards incompatibilities - Applications must now use the ``repoze.bfg.interfaces.ILocation`` interface rather than ``zope.location.interfaces.ILocation`` to represent that a model object is "location-aware". We've removed a dependency on ``zope.location`` for cleanliness purposes: as new versions of zope libraries are released which have improved dependency information, getting rid of our dependence on ``zope.location`` will prevent a newly installed repoze.bfg application from requiring the ``zope.security``, egg, which not truly used at all in a "stock" repoze.bfg setup. These dependencies are still required by the stack at this time; this is purely a futureproofing move. The security and model documentation for previous versions of ``repoze.bfg`` recommended using the ``zope.location.interfaces.ILocation`` interface to represent that a model object is "location-aware". This documentation has been changed to reflect that this interface should now be imported from ``repoze.bfg.interfaces.ILocation`` instead.

2008-08-08 - Add ``find_context_from_path`` and ``find_root`` traversal APIs.Chris McDonough
In the process, make ITraverser a uni-adapter (on context) rather than a multiadapter (on context and request).
2008-08-06 - Small url dispatch overhaul: the ``connect`` method of theChris McDonough
``urldispatch.RoutesMapper`` object now accepts a keyword parameter named ``context_factory``. If this parameter is supplied, it must be a callable which returns an instance. This instance is used as the context for the request when a route is matched. - The registration of a RoutesModelTraverser no longer needs to be performed by the application; it's in the bfg ZCML now.
2008-08-04 - Add a ``request_type`` attribute to the available attributes of aChris McDonough
``bfg:view`` configure.zcml element. This attribute will have a value which is a dotted Python path, pointing at an interface. If the request object implements this interface when the view lookup is performed, the appropriate view will be called. - Remove "template only" views. These were just confusing and were never documented.
