1.2b2 (2010-01-21)

Bug Fixes

• When the Configurator is passed an instance of zope.component.registry.Components as a registry constructor argument, fix the instance up to have the attributes we expect of an instance of repoze.bfg.registry.Registry when setup_registry is called. This makes it possible to use the global Zope component registry as a BFG application registry.

• When WebOb 0.9.7.1 was used, a deprecation warning was issued for the class attribute named charset within repoze.bfg.request.Request. BFG now requires WebOb >= 0.9.7, and code was added so that this deprecation warning has disappeared.

• Fix a view lookup ordering bug whereby a view with a larger number of predicates registered first (literally first, not “earlier”) for a triad would lose during view lookup to one registered with fewer.

• Make sure views with exactly N custom predicates are always called before views with exactly N non-custom predicates given all else is equal in the view configuration.

Documentation

• Change renderings of ZCML directive documentation.

• Add a narrative documentation chapter: “Using the Zope Component Architecture in repoze.bfg”.

Dependencies

• Require WebOb >= 0.9.7

1.2b1 (2010-01-18)

Bug Fixes

• In bfg_routesalchemy, bfg_alchemy paster templates and the bfgwiki2 tutorial, clean up the SQLAlchemy connection by registering a repoze.tm.after_end callback instead of relying on a __del__ method of a Cleanup class added to the WSGI environment. The __del__ strategy was fragile and caused problems in the wild. Thanks to Daniel Holth for testing.

Features

• Read logging configuration from PasteDeploy config file loggers section (and related) when paster bfgshell is invoked.

Documentation

• Major rework in preparation for book publication.

1.2a11 (2010-01-05)

Bug Fixes

• Make paster bfgshell and paster create -t bfg_xxx work on Jython (fix minor incompatibility with treatment of __doc__ at the class level).

• Updated dependency on WebOb to require a version which supports features now used in tests.

Features

• Jython compatibility (at least when repoze.bfg.jinja2 is used as the templating engine; Chameleon does not work under Jython).

• Show the derived abspath of template resource specifications in the traceback when a renderer template cannot be found.

• Show the original traceback when a Chameleon template cannot be rendered due to a platform incompatibility.

1.2a10 (2010-01-04)

Features

• The Configurator.add_view method now accepts an argument named context. This is an alias for the older argument named for_; it is preferred over for_, but for_ will continue to be supported “forever”.

• The view ZCML directive now accepts an attribute named context. This is an alias for the older attribute named for; it is preferred over for, but for will continue to be supported “forever”.

• The Configurator.add_route method now accepts an argument named view_context. This is an alias for the older argument named view_for; it is preferred over view_for, but view_for will continue to be supported “forever”.

• The route ZCML directive now accepts an attribute named view_context. This is an alias for the older attribute named view_for; it is preferred over view_for, but view_for will continue to be supported “forever”.

Documentation and Paster Templates

• LaTeX rendering tweaks.

• All uses of the Configurator.add_view method that used its for_ argument now use the context argument instead.

• All uses of the Configurator.add_route method that used its view_for argument now use the view_context argument instead.

• All uses of the view ZCML directive that used its for attribute now use the context attribute instead.

• All uses of the route ZCML directive that used its view_for attribute now use the view_context attribute instead.

• Add a (minimal) tutorial dealing with use of repoze.catalog in a repoze.bfg application.

This is only a documentation licensing change; the repoze.bfg software continues to be offered under the Repoze Public License at http://repoze.org/license.html (BSD-like).

1.2a9 (2009-12-27)

Documentation Licensing

• The documentation (the result of make <html|latex|htmlhelp> within the docs directory) in this release is now offered under the Creative Commons Attribution-Noncommercial-No Derivative Works 3.0 United States License as described by http://creativecommons.org/licenses/by-nc-nd/3.0/us/ . This is only a licensing change for the documentation; the repoze.bfg software continues to be offered under the Repoze Public License at http://repoze.org/license.html (BSD-like).

Documentation

• Added manual index entries to generated index.

• Document the previously existing (but non-API) repoze.bfg.configuration.Configurator.setup_registry method as an official API of a Configurator.

• Fix syntax errors in various documentation code blocks.

• Created new top-level documentation section: “ZCML Directives”. This section contains detailed ZCML directive information, some of which was removed from various narrative chapters.

• The LaTeX rendering of the documentation has been improved.

• Added a “Fore-Matter” section with author, copyright, and licensing information.

1.2a8 (2009-12-24)

Features

• Add a **kw arg to the Configurator.add_settings API.

• Add hook_zca and unhook_zca methods to the Configurator API.

• The repoze.bfg.testing.setUp method now returns a Configurator instance which can be used to do further configuration during unit tests.

Bug Fixes

• The json renderer failed to set the response content type to application/json. It now does, by setting request.response_content_type unless this attribute is already set.

• The string renderer failed to set the response content type to text/plain. It now does, by setting request.response_content_type unless this attribute is already set.

Documentation

• General documentation improvements by using better Sphinx roles such as “class”, “func”, “meth”, and so on. This means that there are many more hyperlinks pointing to API documentation for API definitions in all narrative, tutorial, and API documentation elements.

• Added a description of imperative configuration in various places which only described ZCML configuration.

• A syntactical refreshing of various tutorials.

• Added the repoze.bfg.authentication, repoze.bfg.authorization, and repoze.bfg.interfaces modules to API documentation.

Deprecations

• The repoze.bfg.testing.registerRoutesMapper API (added in an early 1.2 alpha) was deprecated. Its import now generates a deprecation warning.

1.2a7 (2009-12-20)

Features

• Add four new testing-related APIs to the repoze.bfg.configuration.Configurator class: testing_securitypolicy, testing_models, testing_add_subscriber, and testing_add_template. These were added in order to provide more direct access to the functionality of the repoze.bfg.testing APIs named registerDummySecurityPolicy, registerModels, registerEventListener, and registerTemplateRenderer when a configurator is used. The testing APIs named are nominally deprecated (although they will likely remain around “forever”, as they are in heavy use in the wild).

• Add a new API to the repoze.bfg.configuration.Configurator class: add_settings. This API can be used to add “settings” (information returned within via the repoze.bfg.settings.get_settings API) after the configurator has been initially set up. This is most useful for testing purposes.

• Add a custom_predicates argument to the Configurator add_view method, the bfg_view decorator and the attribute list of the ZCML view directive. If custom_predicates is specified, it must be a sequence of predicate callables (a predicate callable accepts two arguments: context and request and returns True or False). The associated view callable will only be invoked if all custom predicates return True. Use one or more custom predicates when no existing predefined predicate is useful. Predefined and custom predicates can be mixed freely.

• Add a custom_predicates argument to the Configurator add_route and the attribute list of the ZCML route directive. If custom_predicates is specified, it must be a sequence of predicate callables (a predicate callable accepts two arguments: context and request and returns True or False). The associated route will match will only be invoked if all custom predicates return True, else route matching continues. Note that the value context will always be None when passed to a custom route predicate. Use one or more custom predicates when no existing predefined predicate is useful. Predefined and custom predicates can be mixed freely.

Internal

• Remove the repoze.bfg.testing.registerTraverser function. This function was never an API.

Documenation

• Doc-deprecated most helper functions in the repoze.bfg.testing module. These helper functions likely won’t be removed any time soon, nor will they generate a warning any time soon, due to their heavy use in the wild, but equivalent behavior exists in methods of a Configurator.

1.2a6 (2009-12-18)

Features

• The Configurator object now has two new methods: begin and end. The begin method is meant to be called before any “configuration” begins (e.g. before add_view, et. al are called). The end method is meant to be called after all “configuration” is complete.

  Previously, before there was imperative configuration at all (1.1 and prior), configuration begin and end was invariably implied by the process of loading a ZCML file. When a ZCML load happened, the threadlocal data structure containing the request and registry was modified before the load, and torn down after the load, making sure that all framework code that needed get_current_registry for the duration of the ZCML load was satisfied.

  Some API methods called during imperative configuration, (such as Configurator.add_view when a renderer is involved) end up for historical reasons calling get_current_registry. However, in 1.2a5 and below, the Configurator supplied no functionality that allowed people to make sure that get_current_registry returned the registry implied by the configurator being used. begin now serves this purpose. Inversely, end pops the thread local stack, undoing the actions of begin.

  We make this boundary explicit to reduce the potential for confusion when the configurator is used in different circumstances (e.g. in unit tests and app code vs. just in initial app setup).

  Existing code written for 1.2a1-1.2a5 which does not call begin or end continues to work in the same manner it did before. It is however suggested that this code be changed to call begin and end to reduce the potential for confusion in the future.

• All paster templates which generate an application skeleton now make use of the new begin and end methods of the Configurator they use in their respective copies of run.py and tests.py.

Documentation

• All documentation that makes use of a Configurator object to do application setup and test setup now makes use of the new begin and end methods of the configurator.

Bug Fixes

• When a repoze.bfg.exceptions.NotFound or repoze.bfg.exceptions.Forbidden class (as opposed to instance) was raised as an exception within a root factory (or route root factory), the exception would not be caught properly by the repoze.bfg. Router and it would propagate to up the call stack, as opposed to rendering the not found view or the forbidden view as would have been expected.

• When Chameleon page or text templates used as renderers were added imperatively (via Configurator.add_view or some derivative), they too-eagerly attempted to look up the reload_templates setting via get_settings, meaning they were always registered in non-auto-reload-mode (the default). Each now waits until its respective template attribute is accessed to look up the value.

• When a route with the same name as a previously registered route was added, the old route was not removed from the mapper’s routelist. Symptom: the old registered route would be used (and possibly matched) during route lookup when it should not have had a chance to ever be used.

1.2a5 (2009-12-10)

Features

• When the repoze.bfg.exceptions.NotFound or repoze.bfg.exceptions.Forbidden error is raised from within a custom root factory or the factory of a route, the appropriate response is now sent to the requesting user agent (the result of the notfound view or the forbidden view, respectively). When these errors are raised from within a root factory, the context passed to the notfound or forbidden view will be None. Also, the request will not be decorated with view_name, subpath, context, etc. as would normally be the case if traversal had been allowed to take place.

Internals

• The exception class representing the error raised by various methods of a Configurator is now importable as repoze.bfg.exceptions.ConfigurationError.

Documentation

• General documentation freshening which takes imperative configuration into account in more places and uses glossary references more liberally.

• Remove explanation of changing the request type in a new request event subscriber, as other predicates are now usually an easier way to get this done.

• Added “Thread Locals” narrative chapter to documentation, and added a API chapter documenting the repoze.bfg.threadlocals module.

• Added a “Special Exceptions” section to the “Views” narrative documentation chapter explaining the effect of raising repoze.bfg.exceptions.NotFound and repoze.bfg.exceptions.Forbidden from within view code.

Dependencies

• A new dependency on the twill package was added to the setup.py tests_require argument (Twill will only be downloaded when repoze.bfg setup.py test or setup.py nosetests is invoked).

1.2a4 (2009-12-07)

Features

• repoze.bfg.testing.DummyModel now accepts a new constructor keyword argument: __provides__. If this constructor argument is provided, it should be an interface or a tuple of interfaces. The resulting model will then provide these interfaces (they will be attached to the constructed model via zope.interface.alsoProvides).

Bug Fixes

• Operation on GAE was broken, presumably because the repoze.bfg.configuration module began to attempt to import the repoze.bfg.chameleon_zpt and repoze.bfg.chameleon_text modules, and these cannot be used on non-CPython platforms. It now tolerates startup time import failures for these modules, and only raise an import error when a template from one of these packages is actually used.

1.2a3 (2009-12-02)

Bug Fixes

• The repoze.bfg.url.route_url function inappropriately passed along _query and/or _anchor arguments to the mapper.generate function, resulting in blowups.

• When two views were registered with differering for interfaces or classes, and the for of first view registered was a superclass of the second, the repoze.bfg view machinery would incorrectly associate the two views with the same “multiview”. Multiviews are meant to be collections of views that have exactly the same for/request/viewname values, without taking inheritance into account. Symptom: wrong view callable found even when you had correctly specified a for_ interface/class during view configuration for one or both view configurations.

Backwards Incompatibilities

• The repoze.bfg.templating module has been removed; it had been deprecated in 1.1 and never actually had any APIs in it.

1.2a2 (2009-11-29)

Bug Fixes

• The the long description of this package (as shown on PyPI) was not valid reStructuredText, and so was not renderable.

• Trying to use an HTTP method name string such as GET as a request_type predicate argument caused a startup time failure when it was encountered in imperative configuration or in a decorator (symptom: Type Error: Required specification must be a specification). This now works again, although request_method is now the preferred predicate argument for associating a view configuration with an HTTP request method.

Documentation

• Fixed “Startup” narrative documentation chapter; it was explaining “the old way” an application constructor worked.

1.2a1 (2009-11-28)

Features

• An imperative configuration mode.

  A repoze.bfg application can now begin its life as a single Python file. Later, the application might evolve into a set of Python files in a package. Even later, it might start making use of other configuration features, such as ZCML. But neither the use of a package nor the use of non-imperative configuration is required to create a simple repoze.bfg application any longer.

  Imperative configuration makes repoze.bfg competetive with “microframeworks” such as Bottle and Tornado. repoze.bfg has a good deal of functionality that most microframeworks lack, so this is hopefully a “best of both worlds” feature.

  The simplest possible repoze.bfg application is now:

  from webob import Response
  from wsgiref import simple_server
  from repoze.bfg.configuration import Configurator
  
  def hello_world(request):
      return Response('Hello world!')
  
  if __name__ == '__main__':
      config = Configurator()
      config.add_view(hello_world)
      app = config.make_wsgi_app()
      simple_server.make_server('', 8080, app).serve_forever()

• A new class now exists: repoze.bfg.configuration.Configurator. This class forms the basis for sharing machinery between “imperatively” configured applications and traditional declaratively-configured applications.

• The repoze.bfg.testing.setUp function now accepts three extra optional keyword arguments: registry, request and hook_zca.

  If the registry argument is not None, the argument will be treated as the registry that is set as the “current registry” (it will be returned by repoze.bfg.threadlocal.get_current_registry) for the duration of the test. If the registry argument is None (the default), a new registry is created and used for the duration of the test.

  The value of the request argument is used as the “current request” (it will be returned by repoze.bfg.threadlocal.get_current_request) for the duration of the test; it defaults to None.

  If hook_zca is True (the default), the zope.component.getSiteManager function will be hooked with a function that returns the value of registry (or the default-created registry if registry is None) instead of the registry returned by zope.component.getGlobalSiteManager, causing the Zope Component Architecture API (getSiteManager, getAdapter, getUtility, and so on) to use the testing registry instead of the global ZCA registry.

• The repoze.bfg.testing.tearDown function now accepts an unhook_zca argument. If this argument is True (the default), zope.component.getSiteManager.reset() will be called. This will cause the result of the zope.component.getSiteManager function to be the global ZCA registry (the result of zope.component.getGlobalSiteManager) once again.

• The run.py module in various repoze.bfg paster templates now use a repoze.bfg.configuration.Configurator class instead of the (now-legacy) repoze.bfg.router.make_app function to produce a WSGI application.

Documentation

• The documentation now uses the “request-only” view calling convention in most examples (as opposed to the context, request convention). This is a documentation-only change; the context, request convention is also supported and documented, and will be “forever”.

• repoze.bfg.configuration API documentation has been added.

• A narrative documentation chapter entitled “Creating Your First repoze.bfg Application” has been added. This chapter details usage of the new repoze.bfg.configuration.Configurator class, and demonstrates a simplified “imperative-mode” configuration; doing repoze.bfg application configuration imperatively was previously much more difficult.

• A narrative documentation chapter entitled “Configuration, Decorations and Code Scanning” explaining ZCML- vs. imperative- vs. decorator-based configuration equivalence.

• The “ZCML Hooks” chapter has been renamed to “Hooks”; it documents how to override hooks now via imperative configuration and ZCML.

• The explanation about how to supply an alternate “response factory” has been removed from the “Hooks” chapter. This feature may be removed in a later release (it still works now, it’s just not documented).

• Add a section entitled “Test Set Up and Tear Down” to the unittesting chapter.

Bug Fixes

• The ACL authorization policy debugging output when debug_authorization console debugging output was turned on wasn’t as clear as it could have been when a view execution was denied due to an authorization failure resulting from the set of principals passed never having matched any ACE in any ACL in the lineage. Now in this case, we report <default deny> as the ACE value and either the root ACL or <No ACL found on any object in model lineage> if no ACL was found.

• When two views were registered with the same accept argument, but were otherwise registered with the same arguments, if a request entered the application which had an Accept header that accepted either of the media types defined by the set of views registered with predicates that otherwise matched, a more or less “random” one view would “win”. Now, we try harder to use the view callable associated with the view configuration that has the most specific accept argument. Thanks to Alberto Valverde for an initial patch.

Internals

• The routes mapper is no longer a root factory wrapper. It is now consulted directly by the router.

• The repoze.bfg.registry.make_registry callable has been removed.

• The repoze.bfg.view.map_view callable has been removed.

• The repoze.bfg.view.owrap_view callable has been removed.

• The repoze.bfg.view.predicate_wrap callable has been removed.

• The repoze.bfg.view.secure_view callable has been removed.

• The repoze.bfg.view.authdebug_view callable has been removed.

• The repoze.bfg.view.renderer_from_name callable has been removed. Use repoze.bfg.configuration.Configurator.renderer_from_name instead (still not an API, however).

• The repoze.bfg.view.derive_view callable has been removed. Use repoze.bfg.configuration.Configurator.derive_view instead (still not an API, however).

• The repoze.bfg.settings.get_options callable has been removed. Its job has been subsumed by the repoze.bfg.settings.Settings class constructor.

• The repoze.bfg.view.requestonly function has been moved to repoze.bfg.configuration.requestonly.

• The repoze.bfg.view.rendered_response function has been moved to repoze.bfg.configuration.rendered_response.

• The repoze.bfg.view.decorate_view function has been moved to repoze.bfg.configuration.decorate_view.

• The repoze.bfg.view.MultiView class has been moved to repoze.bfg.configuration.MultiView.

• The repoze.bfg.zcml.Uncacheable class has been removed.

• The repoze.bfg.resource.resource_spec function has been removed.

• All ZCML directives which deal with attributes which are paths now use the path method of the ZCML context to resolve a relative name to an absolute one (imperative configuration requirement).

• The repoze.bfg.scripting.get_root API now uses a ‘real’ WebOb request rather than a FakeRequest when it sets up the request as a threadlocal.

• The repoze.bfg.traversal.traverse API now uses a ‘real’ WebOb request rather than a FakeRequest when it calls the traverser.

• The repoze.bfg.request.FakeRequest class has been removed.

• Most uses of the ZCA threadlocal API (the getSiteManager, getUtility, getAdapter, getMultiAdapter threadlocal API) have been removed from the core. Instead, when a threadlocal is necessary, the core uses the repoze.bfg.threadlocal.get_current_registry API to obtain the registry.

• The internal ILogger utility named repoze.bfg.debug is now just an IDebugLogger unnamed utility. A named utility with the old name is registered for b/w compat.

• The repoze.bfg.interfaces.ITemplateRendererFactory interface was removed; it has become unused.

• Instead of depending on the martian package to do code scanning, we now just use our own scanning routines.

• We now no longer have a dependency on repoze.zcml package; instead, the repoze.bfg package includes implementations of the adapter, subscriber and utility directives.

• Relating to the following functions:

  repoze.bfg.view.render_view

  repoze.bfg.view.render_view_to_iterable

  repoze.bfg.view.render_view_to_response

  repoze.bfg.view.append_slash_notfound_view

  repoze.bfg.view.default_notfound_view

  repoze.bfg.view.default_forbidden_view

  repoze.bfg.configuration.rendered_response

  repoze.bfg.security.has_permission

  repoze.bfg.security.authenticated_userid

  repoze.bfg.security.effective_principals

  repoze.bfg.security.view_execution_permitted

  repoze.bfg.security.remember

  repoze.bfg.security.forget

  repoze.bfg.url.route_url

  repoze.bfg.url.model_url

  repoze.bfg.url.static_url

  repoze.bfg.traversal.virtual_root

  Each of these functions now expects to be called with a request object that has a registry attribute which represents the current repoze.bfg registry. They fall back to obtaining the registry from the threadlocal API.

Backwards Incompatibilites

• Unit tests which use zope.testing.cleanup.cleanUp for the purpose of isolating tests from one another may now begin to fail due to lack of isolation between tests.

  Here’s why: In repoze.bfg 1.1 and prior, the registry returned by repoze.bfg.threadlocal.get_current_registry when no other registry had been pushed on to the threadlocal stack was the zope.component.globalregistry.base global registry (aka the result of zope.component.getGlobalSiteManager()). In repoze.bfg 1.2+, however, the registry returned in this situation is the new module-scope repoze.bfg.registry.global_registry object. The zope.testing.cleanup.cleanUp function clears the zope.component.globalregistry.base global registry unconditionally. However, it does not know about the repoze.bfg.registry.global_registry object, so it does not clear it.

  If you use the zope.testing.cleanup.cleanUp function in the setUp of test cases in your unit test suite instead of using the (more correct as of 1.1) repoze.bfg.testing.setUp, you will need to replace all calls to zope.testing.cleanup.cleanUp with a call to repoze.bfg.testing.setUp.

  If replacing all calls to zope.testing.cleanup.cleanUp with a call to repoze.bfg.testing.setUp is infeasible, you can put this bit of code somewhere that is executed exactly once (not for each test in a test suite; in the `` __init__.py`` of your package or your package’s tests subpackage would be a reasonable place):

  import zope.testing.cleanup
  from repoze.bfg.testing import setUp
  zope.testing.cleanup.addCleanUp(setUp)

• When there is no “current registry” in the repoze.bfg.threadlocal.manager threadlocal data structure (this is the case when there is no “current request” or we’re not in the midst of a r.b.testing.setUp-bounded unit test), the .get method of the manager returns a data structure containing a global registry. In previous releases, this function returned the global Zope “base” registry: the result of zope.component.getGlobalSiteManager, which is an instance of the zope.component.registry.Component class. In this release, however, the global registry returns a globally importable instance of the repoze.bfg.registry.Registry class. This registry instance can always be imported as repoze.bfg.registry.global_registry.

  Effectively, this means that when you call repoze.bfg.threadlocal.get_current_registry when no request or setUp bounded unit test is in effect, you will always get back the global registry that lives in repoze.bfg.registry.global_registry. It also means that repoze.bfg APIs that call get_current_registry will use this registry.

  This change was made because repoze.bfg now expects the registry it uses to have a slightly different API than a bare instance of zope.component.registry.Components.

• View registration no longer registers a repoze.bfg.interfaces.IViewPermission adapter (it is no longer checked by the framework; since 1.1, views have been responsible for providing their own security).

• The repoze.bfg.router.make_app callable no longer accepts the authentication_policy nor the authorization_policy arguments. This feature was deprecated in version 1.0 and has been removed.

• Obscure: the machinery which configured views with a request_type and a route_name would ignore the request interface implied by route_name registering a view only for the interface implied by request_type. In the unlikely event that you were trying to use these two features together, the symptom would have been that views that named a request_type but which were also associated with routes were not found when the route matched. Now if a view is configured with both a request_type and a route_name, an error is raised.

• The route ZCML directive now no longer accepts the request_type or view_request_type attributes. These attributes didn’t actually work in any useful way (see entry above this one).

• Because the repoze.bfg package now includes implementations of the adapter, subscriber and utility ZCML directives, it is now an error to have <include package="repoze.zcml" file="meta.zcml"/> in the ZCML of a repoze.bfg application. A ZCML conflict error will be raised if your ZCML does so. This shouldn’t be an issue for “normal” installations; it has always been the responsibility of the repoze.bfg.includes ZCML to include this file in the past; it now just doesn’t.

• The repoze.bfg.testing.zcml_configure API was removed. Use the Configurator.load_zcml API instead.

Deprecations

• The repoze.bfg.router.make_app function is now nominally deprecated. Its import and usage does not throw a warning, nor will it probably ever disappear. However, using a repoze.bfg.configuration.Configurator class is now the preferred way to generate a WSGI application.

  Note that make_app calls zope.component.getSiteManager.sethook( repoze.bfg.threadlocal.get_current_registry) on the caller’s behalf, hooking ZCA global API lookups, for backwards compatibility purposes. If you disuse make_app, your calling code will need to perform this call itself, at least if your application uses the ZCA global API (getSiteManager, getAdapter, etc).

Dependencies

• A dependency on the martian package has been removed (its functionality is replaced internally).

• A dependency on the repoze.zcml package has been removed (its functionality is replaced internally).
