On Zope 2.1.6 if you you pack the database with '0' in the days box and then pack it again with '1' in the days box bad things happen. In our case the first pack resulted in a Data.fs of 17MBytes (not bad from a started point of nearly 2GBytes) the second pack (which I assumed would do nothing) resulted in a Data.fs of 3MBytes. Great I thought, however it also broke most of my site. Some of the symptoms are:

Accessing existing folders gives KeyError Many of my ZClasses are turned into DTML Methods (that is the icon next to them in the folder view is a DTML Method icon) All the instances of the broken classes are broken.

Thankfully I kept backups before performing the packs.

Richard -

A notice was sent out to the list a week or so ago on this - there is a bug in the packing machinery that (as you found) doesn't correctly handle things when you pack to certain time and then subsequently pack to an earlier time. The fix for this is already checked in for 2.2.

Brian You have my apology I did not spot the this notice. I shall move to 2.2 just as soon as it is out of Beta testing. Richard
