Subject: [Problem report] "pack" discards reachable object (was: [Zope] Pack problem with zeo)



Jonathan wrote at 2006-8-21 11:41 -0400:
I have encountered a problem caused by packing Data.fs (pack done via ZMI -
Control Panel - Database Management - main - Pack).  After Data.fs is
packed, the ZODBmount point for the zeo server is missing.

I have the following folder set-up:

Root
  |----Coz
         |---ZeoServer1

After the pack operation, folder 'ZeoServer1' is missing.

That would be a severe bug in "FileStorage" -- and it is almost
unbelievable...

  A mount point is nothing special for a "FileStorage". It is
  treated like any other object.

  What you tell us is that a reachable object can be discarded
  by packing. As a mount point is nothing special, it could
  happen with any object.

  But it is now years back that we got the last packing problem report.


I can reproduce the behaviour very easily... after I pack and the 'ZeoServer1' folder disappears i do the following:

- stop zope
- delete Data.fs
- rename Data.fs.old to Data.fs
- start zope

And the ZeoServer1 folder is back. I then pack zope and the ZeoServer1 folder disappears again. I can do this again and again and again.
