I can see the benefit in being able to supply an error view that handles the error completely, and thus no logging takes place, but I wonder whether this is in active use, and why in that case even such errors end up going to the error reporting utility. I.e. should we unify towards the simple case, or should we be unifying towards the case where something like isSystemError can be defined? Note that there's also a whole machinery, independent of this, to actually have exception side effects, something that the Zope 3 core at least doesn't appear to be using. I wonder whether anyone uses it, and if not, whether we can get rid of it completely.

Hey, Replying to myself: if people feel like digging into things, there are some issues that contain some context: http://www.zope.org/Collectors/Zope3-dev/686/collector_issue_contents I also ran into this independenly in this issue, so it contains lots of contents on this: http://www.zope.org/Collectors/Zope3-dev/558 Regards, Martijn ___ Zope3-dev mailing list Zope3-dev@zope.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com
