2009-09-30- For behavior like Django's ``APPEND_SLASH=True``, use theChris McDonough
``repoze.bfg.view.append_slash_notfound_view`` view as the Not Found view in your application. When this view is the Not Found view (indicating that no view was found), and any routes have been defined in the configuration of your application, if the value of ``PATH_INFO`` does not already end in a slash, and if the value of ``PATH_INFO`` *plus* a slash matches any route's path, do an HTTP redirect to the slash-appended PATH_INFO. Note that this will *lose* ``POST`` data information (turning it into a GET), so you shouldn't rely on this to redirect POST requests.
2009-09-30- The import of ``repoze.bfg.view.NotFound`` is deprecated in favor ofChris McDonough
``repoze.bfg.exceptions.NotFound``. The old location still functions, but emits a deprecation warning. - The import of ``repoze.bfg.security.Unauthorized`` is deprecated in favor of ``repoze.bfg.exceptions.Forbidden``. The old location still functions but emits a deprecation warning. The rename from ``Unauthorized`` to ``Forbidden`` brings parity to the the name of the exception and the system view it invokes when raised. - New ``repoze.bfg.exceptions`` module was created to house exceptions that were previously sprinkled through various modules. - An ``exceptions`` API chapter was added, documenting the new ``repoze.bfg.exceptions`` module.
2009-09-17- Add a ``repoze.bfg.url.static_url`` API which is capable ofChris McDonough
generating URLs to static resources defined by the ``<static>`` ZCML directive. See the "Views" narrative chapter's section titled "Generating Static Resource URLs" for more information.
2009-09-16- The ``repoze.bfg.testing.registerDummyRenderer`` API has beenChris McDonough
deprecated in favor of ``repoze.bfg.testing.registerTemplateRenderer``. A deprecation warning is *not* issued at import time for the former name; it will exist "forever". - The ``repoze.bfg.templating.renderer_from_cache`` function has been moved to ``repoze.bfg.renderer.template_renderer_factory``. This was never an API, but code in the wild was spotted that used it. A deprecation warning is issued at import time for the former. - Better error message when a wrapper view returns None.

2009-07-01- Deprecate the ``authentication_policy`` and ``authorization_policy``Chris McDonough
arguments to ``repoze.bfg.router.make_app``. Instead, developers should use the various authentication policy ZCML directives (``repozewho1authenticationpolicy``, ``remoteuserauthenticationpolicy`` and ``authtktauthenticationpolicy``) and the `aclauthorizationpolicy`` authorization policy directive as described in the changes to the "Security" narrative documentation chapter and the wiki tutorials.
2009-06-24- Added the ``repoze.bfg.url.route_url`` API. This is meant toChris McDonough
"front" for the Routes ``url_for`` API. See the URL Dispatch narrative chapter and the "repoze.bfg.url" module API documentation for more information.

2009-06-19Edit.Chris McDonough
2009-06-02- Add API named ``repoze.bfg.settings.get_settings`` which retrieves aChris McDonough
derivation of values passed as the ``options`` value of ``repoze.bfg.router.make_app``. This API should be preferred instead of using getUtility(ISettings). I added a new ``repoze.bfg.settings`` API document as well.
2009-06-02- The ``repoze.bfg.location.locate`` API was removed: it didn't doChris McDonough
enough to be very helpful and had a misleading name.
2009-06-02Remove this from the docs.Chris McDonough
2009-06-02- Add ``repoze.bfg.request.current_request`` function. This functionChris McDonough
should be used (**very sparingly**) to retrieve the "current" request. See the ``repoze.bfg.request`` API documentation for more information.
2009-05-30Docs.Chris McDonough
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.

2009-05-18FeaturesChris McDonough
-------- - 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.
