[Zope] Re: zope on google file system
As an experiment, I started porting zodb to amazon s3 storage a while ago... http://code.google.com/p/s3storage/ You can use it to start zope, but it makes far too many writes inefficiently (it took about 15 minutes for zope2 to create all it's objects on a first start). Now that ec2 comes with static IP addresses, I might end up looking at it again. It needs refactoring to write only one file per transaction (or savepoint), but once done I would imagine it might then offer reasonable performance.

[Zope] ZSyncer Zope 2.10
Hello All, We've recently completed an upgrade to Zope 2.10.5 on one of our servers and we've begun to encounter problems with ZSyncer. We use ZSyncer to synchronize objects between this server and another running Zope 2.9.8 (both have ZSyncer 0.7.1 installed). When attempting to put folders from the 2.10 server to the 2.9 server, the process hangs and nothing is transferred. However, when we attempt to put individual objects, we are successful. Does anyone know what might be the cause of this issue? ZSyncer 0.7.1, which is the latest release, claims that it may not be compatible with Zope 2.9 and up, but we were able to use it successfully before this most recent upgrade to 2.10. If anyone is aware of a fix or a workaround, or simply has an insight into why this breaks for us, I would greatly appreciate the help.

[Zope] RE: Managing Zope objects in Subversion
Dear all I would like to thank all those who have responded to my query about management of Zope objects in Subversion. After I sent out my message on 2 March, I got completely side-tracked by other business. Please accept my apologies for this late response. I've experimented with FSDump and FileSystemSite, but that's a one-way solution; i.e., I cannot restore the file system back into ZODB. For me, the most promising respone was: From: Sam Rangaswamy [EMAIL PROTECTED] Sent: Sunday, March 02, 2008 5:46 PM Subject: Re: [Zope] Managing Zope objects in Subversion Hello Martin We use subversion extensively to manage our entire product development life cycle. We have built tools to move source code back and forth between file system and zodb. I will have it documented and share it with you and publish it. I think it may be useful. Best sam I will gladly wait until Sam publishes their tools, and I think this will be useful to the community indeed. Thank you in advance, Sam!

I've never tried ZSyncer with Zope 2.10; I don't have any guesses what your problem is. Have you tried syncing between two 2.10 instances? In general, you move data from 2.X to 2.X-1 at your own risk, whether using ZSyncer or the import/export tab in the ZMI. I've been the official ZSyncer maintainer for about 5 years now, but honestly I've barely touched it since 2005, since in its current state it works well enough on the rare occasions that I need it. If somebody else cares enough about ZSyncer to maintain it, please contact me. Otherwise, to be crassly honest, I'm unlikely to do any ZSyncer-related work unless somebody pays me to do so. -- Paul Winkler http://www.slinkp.com ___ 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 )

Apparently, your titles are plain strings. Therefore, Python needs to convert them to unicode at the WebDAV boundary. Obviously, an encoding is necessary to do this -- and as no explicit encoding is given, Python's defaultencoding is used (which defaults to ascii). The most proper solution would be to make your titles unicode. If all your plain strings use a common encoding, then you can set Python's defaultencoding to this encoding. You must do that at startup (e.g. in sitecustomize.py), as setdefaultencoding is removed from sys after startup. -- Dieter ___ 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 )

Re: [Zope] Re: zope on google file system
This is what I love about zope. It can be a much more flexible way to store data than in a relational db. Maybe some combination of zodb and s3 would be efficient. Zodb for frequently used business objects and a library (localfs modified ?) for storing data documents on s3. Could you update your plan when you get time? Thanks!
