2009-01-22- ``repoze.bfg.traversal.split_path`` now also handles decodingChris McDonough
path segments to unicode (for speed, because its results are LRU cached). - ``repoze.bfg.traversal.step`` was made a method of the ModelGraphTraverser.
2009-01-22- The ``unicode_path_segments`` configuration variable and theChris McDonough
``BFG_UNICODE_PATH_SEGMENTS`` configuration variable have been removed. Path segments are now always passed to model ``__getitem__`` methods as unicode. "True" has been the default for this setting since 0.5.4, but changing this configuration setting to false allowed you to go back to passing raw path element strings to model ``__getitem__`` methods. This services a speed goal (we get about +80 req/s by removing the check), and it's clearer just to always expect unicode path segments in model ``__getitem__`` methods.

Bug Fixes --------- - Fix a bug where the Paste configuration's ``unicode_path_segments`` (and os.environ's ``BFG_UNICODE_PATH_SEGMENTS``) may have been defaulting to false in some circumstances. It now always defaults to true, matching the documentation and intent. - The ``repoze.bfg.traversal.find_model`` API did not work properly when passed a ``path`` argument which was unicode and contained high-order bytes when the ``unicode_path_segments`` or ``BFG_UNICODE_PATH_SEGMENTS`` configuration variables were "true". - A new module was added: ``repoze.bfg.settings``. This contains deployment-settings-related code. Behavior Changes ---------------- - The ``make_app`` callable within ``repoze.bfg.router`` now registers the ``root_policy`` argument as a utility (unnamed, using the new ``repoze.bfg.interfaces.IRootFactory`` as a provides interface) rather than passing it as the first argument to the ``repoze.bfg.router.Router`` class. As a result the ``repoze.bfg.router.Router`` router class only accepts a single argument: ``registry``. The ``repoze.bfg.router.Router`` class retrieves the root policy via a utility lookup now. The ``repoze.bfg.router.make_app`` API also now performs some important application registrations that were previously handled inside ``repoze.bfg.registry.makeRegistry``. - The ``repoze.bfg.settings.Settings`` class (an instance of which is registered as a utility providing ``repoze.bfg.interfaces.ISettings`` when any application is started) now automatically calls ``repoze.bfg.settings.get_options`` on the options passed to its constructor. This means that usage of ``get_options`` within an application's ``make_app`` function is no longer required (the "raw" ``options`` dict or None may be passed). Deprecations ------------ - Moved the ``repoze.bfg.registry.Settings`` class. This has been moved to ``repoze.bfg.settings.Settings``. A deprecation warning is issued when it is imported from the older location. - Moved the ``repoze.bfg.registry.get_options`` function This has been moved to ``repoze.bfg.settings.get_options``. A deprecation warning is issued when it is imported from the older location. - The ``repoze.bfg.interfaces.IRootPolicy`` interface was renamed within the interfaces package. It has been renamed to ``IRootFactory``. A deprecation warning is issued when it is imported from the older location.
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.
2008-12-18 - Speed up ``traversal.model_url`` execution by using a custom urlChris McDonough
quoting function instead of Python's ``urllib.quote``, by caching URL path segment quoting and encoding results, and by disusing Python's ``urlparse.urljoin`` in favor of a simple string concatenation.
2008-12-17 - In the past, during traversal, the ModelGraphTraverser (theChris McDonough
default traverser) always passed each URL path segment to any ``__getitem__`` method of a model object as a byte string (a ``str`` object). Now, by default the ModelGraphTraverser attempts to decode the path segment to Unicode (a ``unicode`` object) using the UTF-8 encoding before passing it to the ``__getitem__`` method of a model object. This makes it possible for model objects to be dumber in ``__getitem__`` when trying to resolve a subobject, as model objects themselves no longer need to try to divine whether or not to try to decode the path segment passed by the traverser. Note that since 0.5.4, URLs generated by repoze.bfg's ``model_url`` API will contain UTF-8 encoded path segments as necessary, so any URL generated by BFG itself will be decodeable by the traverser. If another application generates URLs to a BFG application, to be resolved successully, it should generate the URL with UTF-8 encoded path segments to be successfully resolved. The decoder is not at all magical: if a non-UTF-8-decodeable path segment (e.g. one encoded using UTF-16 or some other insanity) is passed in the URL, BFG will raise a ``TypeError`` with a message indicating it could not decode the path segment. To turn on the older behavior, where path segments were not decoded to Unicode before being passed to model object ``__getitem__`` by the traverser, and were passed as a raw byte string, set the ``unicode_path_segments`` configuration setting to a false value in your BFG application's section of the paste .ini file, for example:: unicode_path_segments = False Or start the application using the ``BFG_UNICODE_PATH_SEGMENT`` envvar set to a false value:: BFG_UNICODE_PATH_SEGMENTS=0
2008-12-14 Backwards IncompatibilitiesChris McDonough
- URL-quote "extra" element names passed in as ``**elements`` to the ``traversal.model_url`` API. If any of these names is a Unicode string, encode it to UTF-8 before URL-quoting. This is a slight backwards incompatibility that will impact you if you were already UTF-8 encoding or URL-quoting the values you passed in as ``elements`` to this API. Bugfixes - UTF-8 encode each segment in the model path used to generate a URL before url-quoting it within the ``traversal.model_url`` API. This is a bugfix, as Unicode cannot always be successfully URL-quoted.
2008-11-19 - Fix ModelGraphTraverser; don't try to change the ``__name__`` orChris McDonough
``__parent__`` of an object that claims it implements ILocation during traversal even if the ``__name__`` or ``__parent__`` of the object traversed does not match the name used in the traversal step or the or the traversal parent . Rationale: it was insane to do so. This bug was only found due to a misconfiguration in an application that mistakenly had intermediate persistent non-ILocation objects; traversal was causing a persistent write on every request under this setup. - ``repoze.bfg.location.locate`` now unconditionally sets ``__name__`` and ``__parent__`` on objects which provide ILocation (it previously only set them conditionally if they didn't match attributes already present on the object via equality). Prep for 0.5.0.
2008-11-12 - ``repoze.bfg.traversal.model_url`` now always appends a slash toChris McDonough
all generated URLs unless further elements are passed in as the third and following arguments. Rationale: views often use ``model_url`` without the third-and-following arguments in order to generate a URL for a model in order to point at the default view of a model. The URL that points to the default view of the *root* model is technically ``http://mysite/`` as opposed to ``http://mysite`` (browsers happen to ask for '/' implicitly in the GET request). Because URLs are never automatically generated for anything *except* models by ``model_url``, and because the root model is not really special, we continue this pattern. The impact of this change is minimal (at most you will have too many slashes in your URL, which BFG deals with gracefully anyway). Prep for 0.4.8.
2008-11-10 - The ``model_path`` and ``model_url`` traversal APIs returned theChris McDonough
wrong value for the root object (e.g. ``model_path`` returned ``''`` for the root object, while it should have been returning ``'/'``). Prep for 0.4.6.
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.

2008-07-20 - Add find_interface API.Chris McDonough
2008-07-19 - The concept of "view factories" was removed in favor of alwaysChris McDonough
calling a view, which is a callable that returns a response directly (as opposed to returning a view). As a result, the ``factory`` attribute in the bfg:view ZCML statement has been renamed to ``view``. Various interface names were changed also. - ``render_template`` and ``render_transform`` no longer return a Response object. Instead, these return strings. The old behavior can be obtained by using ``render_template_to_response`` and ``render_transform_to_response``.
