[Zope-dev] ZODB cache age

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 a

Hi, Over the last month or so, I've rather wonderfully managed to corrupt my ZODB with artifacts of my Currency class that no longer exist. This is due to: (i) moving the module to a different package (twice) (ii) renaming the module (iii) changing it's inheritance hierarchy (having removed all

Has anyone had a chance to test ZODB 3.2b3? We're hoping to do a release candidate tomorrow, and it would be good to know if anyone has tried to the beta release. If you've got a current CVS checkout of Zope 2.7, that's got the same code. Jeremy ___
