From 86ed4016ea6a681d4f579ace62cea032a679544d Mon Sep 17 00:00:00 2001 From: Chris McDonough Date: Sun, 24 May 2009 23:12:59 +0000 Subject: Features -------- - It is now possible to write a custom security policy that returns a customized ``Forbidden`` WSGI application when BFG cannot authorize an invocation of a view. To this end, ISecurityPolicy objects must now have a ``forbidden`` method. This method should return a WSGI application. The returned WSGI application should generate a response which is appropriate when access to a view resource was forbidden by the security policy (e.g. perhaps a login page). ``repoze.bfg`` is willing to operate with a custom security policy that does not have a ``forbidden`` method, but it will issue a warning; eventually security policies without a ``forbidden`` method will cease to work under ``repoze.bfg``. Note that the ``forbidden`` WSGI application returned by the security policy is not used if a developer has registered an IForbiddenAppFactory (see the "Hooks" narrative chapter); the explicitly registered IForbiddenAppFactory will be preferred over the (more general) security policy forbidden app factory. - All default security policies now have a ``forbidden`` callable attached to them. This particular callable returns a WSGI application which generates a ``401 Unauthorized`` response for backwards compatibility (had backwards compatibility not been an issue, this callable would have returned a WSGI app that generated a ``403 Forbidden`` response). Backwards Incompatibilities --------------------------- - Custom NotFound and Forbidden (nee' Unauthorized) WSGI applications (registered a a utility for INotFoundAppFactory and IUnauthorizedAppFactory) could rely on an environment key named ``message`` describing the circumstance of the response. This key has been renamed to ``repoze.bfg.message`` (as per the WSGI spec, which requires environment extensions to contain dots). Deprecations ------------ - The ``repoze.bfg.interfaces.IUnauthorizedAppFactory`` interface has been renamed to ``repoze.bfg.interfaces.IForbiddenAppFactory``. --- repoze/bfg/wsgi.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'repoze/bfg/wsgi.py') diff --git a/repoze/bfg/wsgi.py b/repoze/bfg/wsgi.py index abe7ebead..027345673 100644 --- a/repoze/bfg/wsgi.py +++ b/repoze/bfg/wsgi.py @@ -105,7 +105,7 @@ def wsgiapp2(wrapped): class HTTPException(object): def __call__(self, environ, start_response, exc_info=False): try: - msg = escape(environ['message']) + msg = escape(environ['repoze.bfg.message']) except KeyError: msg = '' html = """ -- cgit v1.2.3
