The old ZODB object cache had a notion of cache age. Objects that hadn't been accessed within a certain time were removed from the cache. This feature was removed in Zope 2.6, but all of the APIs that controlled the age (sometimes called cacheDeactivateAfter) were kept around. I'd like to mark all of these APIs as deprecated. That includes manage_cache_age in App.CacheManager and a handful of methods in ZODB.DB. Does anyone have a problem with that? Jeremy
