This indicates that "fsrefs" does not understand the data. There are several possible causes: * "fsrefs" does not have the correct version * "fsrefs" has a bug * your storage is damaged. As you have reported that the storage content could be successfully exported, a damage is not that likely (the export should have the same problem in this case). > >I think I can see some corruption in the oids of the referenced objects >as they show as: >\x00\x00\x00\x00\x00\x11'@ >\x00\x00\x00\x00\x00#\xd4\xa9 >\x00\x00\x00\x00\x00\x11'* >etc... - i wasn't expecting to see [EMAIL PROTECTED] and friends. This does not indicate any corruption: the oids are treated as 8 byte binary strings. If a byte has a printable representation, this one is used on printing, otherwise its hex representation. >For example, fsrefs reports not being able to find >'\x00\x00\x00\x00\x00#\xd4"'. However, I can load the database at the >zopectl prompt and load objects, and get ob._p_oid to report >'\x00\x00\x00\x00\x00#\xd4"'. Looks like an "fsrefs" bug. If you can load an object from the storage, "fsrefs" should not report it as missing. >I also wondered if the first few bytes of the database could have been >cut off This is unlikely. The first bytes contain a magic number (identifying the storage format). I think, a "FileStorage" would not open when the magic number were unrecognizable. -- Dieter _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
