The original issue reported in https://bugs.launchpad.net/zope2/+bug/372632 seems to be fixed. The issue discussed in comment #15 and later is basically the same as in https://bugs.launchpad.net/zope-cmf/+bug/558340. So there is only *one* issue: If errors are rendered by 'raise_standardErrorMessage' or by an error view they are not re-raised. In that case the error handling in 'publish_module_standard' and 'HTTPResponse.exception' is no longer invoked. I'm not sure how to resolve this. Approach 1: We try to restore the old behavior. The changes were made because the old machinery didn't work with exceptions like zope.publisher.interfaces.NotFound, but I'm optimistic we can find a less intrusive fix for that. Approach 2: The _unauthorized call seems to be the only part of the old error handling that people are actually missing. We could try to add a new hook for that and deprecate big parts of the old code. But is that old code really useless? >> and a workaround for the CookieCrumbler issue: >> http://dev.plone.org/collective/changeset/92340 > > Hmm, registering an exception view which re-raises the exception is > definitely suggestive of something wrong in the plumbing. Yes. But *if* we don't want restore the old behavior, we could move CookieCrumbler's complete redirect logic into an error view. And get rid of _unauthorized.
