Try making a temp directory for the blob storage, setting up a blob storage around the demo storage, and then cleaning up the temp dir at the end of the test. ...or something else, depending on your use case/testing needs. :-) Gary ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

[Zope3-Users] Using z3c.extfile with ZEO
Hello, I am trying to use z3c.extfile on clients running ZEO. My zope.conf has the following configuration: zodb zeoclient server localhost:8101 storage 1 blob-dir var/blob cache-size 20MB /zeoclient /zodb Then I get the following error: 2008-04-20T23:13:54 ERROR ZODB.Connection Couldn't load state for 0x0de14f Traceback (most recent call last): File /root/workspace/eggs/tmpZKaS-m/ZODB3-3.8.0-py2.5-linux-i686.egg/ZODB/Connection.py, line 804, in setstate File /root/workspace/eggs/tmpZKaS-m/ZODB3-3.8.0-py2.5-linux-i686.egg/ZODB/Connection.py, line 869, in _setstate File /root/workspace/eggs/ZODB3-3.8.0-py2.5-linux-i686.egg/ZEO/ClientStorage.py, line 1034, in loadBlob self._server.sendBlob(oid, serial) File /root/workspace/eggs/tmpZKaS-m/ZODB3-3.8.0-py2.5-linux-i686.egg/ZEO/ServerStub.py, line 289, in sendBlob File /root/workspace/eggs/tmpZKaS-m/ZODB3-3.8.0-py2.5-linux-i686.egg/ZEO/zrpc/connection.py, line 679, in call AttributeError: 'FileStorage' object has no attribute 'loadBlob' Does that mean the FileStroage on the ZEO server doesn't support Blob?

Yes, I was off track a little with my last mail. I did get that I need to replace ModuleProxy as you say. I'm trying to figure just what is required of the ModuleProxy class (if not to be as complete as zope.proxy.ProxyBase). I'm not doing very well with understanding _zope_proxy_proxy.c to even figure out what ProxyBase does provide. I hope this hint helps. Well, yes.
