I *think* Shane Hathaway recently fixed a similar versions bug. Hopefully he'll pipe up. Cees de Groot wrote:

This morning, I wanted to save a big chunk of changes and noticed that after doing "Save", changed documents were still marked with the red diamond and that outside the version, the base folder suddenly gave a key error. Undoing the save luckily restored the status quo, and so it was time to hunt the Zope.org site for information.

I noticed that similar behaviour has been reported a couple of times last year on the mailing lists, and except for a very old instance I never saw a response from an "official" on what can cause this, what one can do to prevent this, and whether this will be fixed, ever.

The work-around I picked up from previous reports (packing the database and retrying) worked beautifully in my case, but is generally not acceptable: we host a lot of websites on this system, our dealers are constantly building/modifying customer sites and I'm only dimly aware of when they are busy. It is of course not very nice that every time I want to save a version, I have to kill their undo history by packing the DB (I usually don't pack the DB, and if I do at +30 days).

So: 1. Is this a problem that can be avoided in some way? 2. Will it be fixed?

Regards,

Cees
