You can't use rsync on Data.fs when Zope is running though. You will have to shut down both the source Zope (to prevent writs during sync) and the target Zope. The latter because FileStorage wasn't designed to have it's datastore shift around underneath it. What do you need load balancing for anyway? Is it for scalability, or for reliability? If you want scalability, surely the cost for ZEO can be justified? Also, do realize that Zope on a single machine can scale pretty awesome. We recon ZEO is only necessary for the absolute top range of websites. Zope.org runs on a single machine, just flexing its muscles a bit on 2 million hits per month. If you want reliability, why not have a second machine on standby, to take over in case of failure? I am sure that tweaking FileStorage to hold back from Data.fs for a backup wouldn't be that hard. This is not strictly necessary either, you'd only miss the transaction or so. You can then have the back-up Zope take over when a monitoring process deems it necessary. -- Martijn Pieters, Software Engineer | Digital Creations http://www.digicool.com | Creators of Zope http://www.zope.org | mailto:mj@digicool.com ICQ: 4532236 | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 -------------------------------------------

RE: [Zope] Worldpilot - logon

that depends on what imap server you are accessing for the mail content. WorldPilot does not "create" users for itself, it asks the imap server that you specified upon instantiating the WorldPilot if the username and password are existing and correct. if you run the standard wu-imap that comes with most linux distros on localhost your login will be your username/password that you use to log into linux. jens -----Original Message----- From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On Behalf Of Graham Chiu Sent: Saturday, February 19, 2000 01:26 To: zope(a)zope.org Subject: [Zope] Worldpilot - logon Hi, Installed this product.

Jet DA
by Jonothan Farr 19 Feb '00

19 Feb '00

I decided to write a database adapter just for fun and education so I slapped together this adapter for the Jet (MS Access) engine using Mark Hammond's infinitely cool win32com extensions. I can't imagine it actually being useful to anyone but it seems to work pretty well and I figure, what the heck? http://www.zope.org/Members/jfarr/Products/ZJetDA --jfarr

Problems with ZClasses...
by jiva＠devware.com 19 Feb '00

19 Feb '00

Okay, I'm trying to grok zclasses. Admitably, my Zope Zen quotient is very low right now, but I'm trying. My problem is, I create a ZClass, and I try to pop an index_html into the ZClass. I can view it from the products screen, but when I create an instance of it and try to access it, it prompts me for a username and password, but I haven't even defined any security on the file. This is in the same folder that I can access other items just fine. What am I missing? -- Man is the only animal that can remain on friendly terms with the victims he intends to eat until he eats them. -- Samuel Butler (1835-1902)

I don't know about Samba, but Jim Fulton warns against _accessing_ Data.fs over NFS. It is a surefire way of corrupting it. About sharing the Data.fs between multiple Zope processes: Don't do it, it doesn't work. The Data.fs file is locked by the Zope process using it for a reason. For load balancing like this yuo will have to go with either ZEO, or some form of XML-RPC based load balancing (ie. write your own). -- Martijn Pieters, Software Engineer | Digital Creations http://www.digicool.com | Creators of Zope http://www.zope.org | mailto:mj@digicool.com ICQ: 4532236 | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 -------------------------------------------

Hey WorldPilot authors, you have a bug
by Tom Neff 19 Feb '00

19 Feb '00

I am posting this to Zope Digest since the N & H people have no Bug Collector of their own on the WorldPilot site, and I don't know how to get through to them otherwise. If you know anybody who works for them, please pass this on. There is a bug in WorldPilot 1.0 release 1 that causes a re.split error if you have certain kinds of IMAP folder names, e.g. an all numeric one like "2000". The problem is that in WorldPilot.py around line 415 you have 414 for folder in FS: 415 FolderFullName=folder[2] 416 cf=rf 417 Folders=re.split(r'\.', FolderFullName) but apparently folder[2] may not be a string if the IMAP name looked un-stringlike. The following change fixes the problem and lets you work with any IMAP folder name: 415 FolderFullName=str(folder[2]) I really like the looks of WorldPilot - all it lacks to be a really killer app is a search function.
