RE: [Zope] reading zope.config file for ClientStorage
OK, the opts object really did have everything loaded. On careful inspection the opts.configroot has an attribute "databases" with a list of Zope.Startup.datatypes.ZopeDatabase instances. I can do what I originally set out to do which was to open a ZEO.ClientStorage configured from the zope-with-zeo.conf file (the ZEO.ClientStorage is now wrapped in a ZEOClient object): from Zope.Startup import options, handlers opts = options.ZopeOptions() opts.configfile='c:\Zope-Instance-Test\etc\zope-with-zeo.conf' opts.load_schema() opts.load_configfile() for db in opts.configroot.databases: if is instance(db.config.storage, ZODB.config.ZEOClient): db.config.storage.open() >What does your zope-with-zeo.conf file look like? My zope-with-zeo.conf file is pretty standard except for a designation to use a zeoclient. I've also included a username and password as my zeo server is using digest authentication: mount-point / server localhost:8090 storage 1 name zeostorage var $INSTANCE/var username metalfor password my_zeo_cleartext_password Thanks much!

RE: [Zope] reading zope.config file for ClientStorage
I've taken a look at stepper and dug into the zope source again. It looks like both are relying on a startup script akin to zopectl to marshal everything correctly. I would rather not be using a startup script (besides I couldn't sort it out); this is what I have so far: from Zope.Startup import options, handlers opts = options.ZopeOptions() opts.configfile='c:\Zope-Instance-Test\etc\zope-with-zeo.conf' opts.load_schema() opts.load_configfile() unfortunately in the resulting options object, I'm not getting the stuff I need from the conf file, namely the ZODB storage stuff needed for ClientStorage. The schema file that is being used by ZopeOptions is Zope/Startup/zopeschema.xml. This only has a skeleton zodb_db section. It looks like the meat & potatoes are in ZODB/component.xml, but I don't see how that is actually pulled in. Any more ideas?

Any ideas? Have a look at the run.py file in Stepper: http://www.simplistix.co.uk/software/zope/stepper It shows you how to parse zope.conf without having to start Zope up... You may wish to wait for Stepper 1.3.0, though, which shows you how to do this for both Zope 2.7 and Zope 2.8... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] reading zope.config file for ClientStorage
To initialize ZEO clients with ClientStorage I need info such as host, port, etc. All the needed stuff is tucked away nicely in the zope.config file and I would like to be using the zope machinery access it. I know that what I need is in there somewhere, but when I try to follow how it happens in say the Zope startup, I get lost in all the dependencies and my head starts swirling. I would like to be able to use something like is in ZODB/config.py: class ZEOClient(BaseConfig): def open(self): from ZEO.ClientStorage import ClientStorage # config.server is a multikey of socket-address values # where the value is a socket family, address tuple. L = [server.address for server in self.config.server] return ClientStorage( L, storage=self.config.storage, cache_size=self.config.cache_size, name=self.config.name, client=self.config.client, var=self.config.var, min_disconnect_poll=self.config.min_disconnect_poll, max_disconnect_poll=self.config.max_disconnect_poll, wait=self.config.wait, read_only=self.config.read_only, read_only_fallback=self.config.read_only_fallback, username=self.config.username, password=self.config.password, realm=self.config.realm) here BaseConfig has that bit of magic that has self.config. I guess I need to know how to instantiate this class. Any ideas? David P.

RE: [Zope] ZEO client authentication
Thanks! Works great.

[Zope] ZEO client authentication
I see that ZEO supports a simple digest authenitcation of clients and that this is set in the zeo's config file with the keys: authentication-protocol, authentication-database and authentication-realm. Further, I can see that a client can connect using e.g. ZEO.ClientStorage with arguments for a userid & password (set in the ZEO authentication database). However, how does one configure Zope (as a client to the ZEO server) to use this authentication? I see nothing in the Zope config file. Somehow Zope must be able to pass a valid userid and password in the authentication database to ZEO.
