I think I've tracked down the problem. Cacheable did not inherit from
Persistent. I was infact using a super class of Cacheable called
NamedCacheable which inherited Acquisition.Implicit which I'd thought was
enough (a long time ago when I wrote it).
Just for the record, how I tracked this down was by using dumps. In pdb I
did
from pickle import dumps
pp state['attributename']
until I found the parts of the state that raised errors.

[Zope] Re: UnpickleableError: Cannot pickle objects
I think I've tracked it down to a RamCacheManager inside a volitile
variable. But I thought volitile variables we'ren't stored? Am I doing
something strange with my heirachy that is abusing the ZODB? The heirachy is
object.[Cacheable] And the Cacheable has _v_ZCacheable_cache =
RamCacheManager. I believe the RamCacheManager has locks in it.

Good suggestion (I did try to get debugging working in WingIDE and Boa but
your way worked best in the end).
Unfortunatly I'm still none the wiser.
I know which object it is and I've looked at its state (below). I've looked
at the OOBTree and made sure it contains nothing that has a lock in it. I
can look at sys.exc_info[1].args which is a lock object but what I really
need to do is work out where this lock object is and why its entangled with
my transaction. Any suggestions?

[Zope] Single worklist for documents with different states?
I've implemented a workflow (in Plone Workflow, derived from DCWorkflow), and would like my reviewers to see a "worklist" portal. However, since I have two reviewer roles that must independently review the document, I have two intervening states in my workflow (ie: "needAB" then either "needA" or "needB" and then "submitted"). I'd like the "A" reviewers to see documents in the "needA" and "needAB" states, while the reviewers see documents in "needB" and "needAB" states. Of course, I'm presuming these will be separate worklists. Is there some other way to implement these worklists? I can create a "portal_tab" which pulls a ZPT that generates the list of items on which the member could work (as Owner, Editor or one of the reviewer roles), but I was hoping to make the worklists work in the short term.

[Zope] Zope Corp and Z3ECM
Zope Corporation is delighted to announce its active participation in the Zope 3 Enterprise Content Management project recently organized by Nuxeo and joined by a number of community members. It's clear that the Zope Community will benefit from a consolidation of common patterns and their implementations in order to grow Zope's market share and we are excited to participate in this effort. In conjunction with the Zope Foundation we expect the Z3ECM project to set the example for global collaboration on sophisticated content management functionality and its application. We are looking forward to launching the Foundation with community involvement so that the Z3ECM project can safely share in the Zope brand. We would like to sincerely thank all of the pioneers who planted the seeds for this effort at the recent sprints (Castle, Paris, etc.). We know from first-hand, large-scale commercial experience that Zope 3 will excel at supporting this effort. Zope Corporation has been making substantial investments in Zope 3 evolution and associated add-on componentry for the last year. An example of this investment is the XML Process Definition Language (XPDL) support that is now available in Zope 3. XPDL support is the first in a series of substantial, customer-inspired contributions that Zope Corporation will be making to the ZECMP over the coming months. Together with Nuxeo's significant ongoing investment in CPS (the Zope 3 version of which will also be contributed to the Z3ECM) we expect the platform will quickly evolve to be the world-leading content management platform. We also propose a name change to the project from Z3ECM to Zope Enterprise Content Management Platform (ZECMP). This will allow the project to disassociate from Zope 3 (it seems likely that there will be 2.8/"5" ports of many/most capabilities). It also makes for a natural transition to the Zope Foundation when that's available in the early Fall. Thanks again to everyone who has helped get Zope 3 and these ideas to this exciting point!

[Zope] ANNOUNCE: Zope Foundation
Zope Corporation has begun the process of creating a Zope Foundation. The Zope Foundation will provide a mechanism for managing the various Zope projects (e.g., Zope 2, the Zope CMF, Zope 3, and other Zope community projects) in a vendor neutral way. The Foundation will have global copyrights over the Zope source code (to include Zope 2, Zope 3, and any other projects managed by the Foundation) as well as a limited, world-wide, non-exclusive, irrevocable, perpetual license to use the Zope trademarks (i.e., "Zope" and the "Circle Z") to brand its software releases. In addition, zope.org will be operated and maintained by the Foundation. The Foundation's governance mechanisms are being developed by taking the most appropriate ideas from other leading open source projects. These mechanisms are being developed and legally reviewed. We will launch the Foundation by or before the end of October 2005. We have scheduled an IRC session to answer questions from the community about the Foundation. IRC Session Summary: - Who: Zope Corp and Zope Community - What: IRC session to discuss the Zope Foundation - When: Tue, 21 Jun 2005 10a - 12p (US EDT) - Where: irc.freenode.net #zope Please send specific questions to: mailto:[EMAIL PROTECTED] We hope to see you there!

The only "gotcha" I've encountered is where the products were out of sync between instances.

I have a nagging feeling I'm missing something here...which I think flows form your use of the term "settings" - would you care to expand on what objects you are thinking of? -- Regards, PhilK Email: [EMAIL PROTECTED] PGP Public key: http://www.xfr.co.uk Voicemail & Facsimile: 07092 070518 "You'll find that one part's sweet and one part's tart: say where the sweetness and the sourness start." - Tony Harrison ___ 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] ZEO recommended for single-cpu?
Also, concerning multi-cpu, I think it's the other way around. Because python processes only use one CPU, it's useless to run one Zope instance on a multi-cpu system, as only one CPU will be used. That's why on multi-cpu system lots of people run at least Zeo + one instance of Zope (and often one Zope instance per CPU). But Zeo is really lightweight, so it's worth trying to use Zeo+Zope on a single cpu system, to take advantage of what Chris describes below.

Zope allows free mixing of content, code and configuration, so working out which parts are which, in order to update code and configuration while leaving content alone, is up to you as the maintainer of the individual solution. If you can tell which parts of the OFS tree represent the data, vs. which parts represent the code and configuration you want to update, exporting the appropriate folders/objects from your development system and importing them to your live one may do the job, or at least get you most of the way there. If it's not that simple - if you've got objects (eg tools) containing both configuration and content, you can't avoid having to do a bit more work, but that doesn't mean there's no alternative to the time-consuming and error-prone approach of manually re-applying your changes. Anything you can do in the ZMI can be done in code, so these configuration changes can be scripted, and the script can be tested on a fresh copy of the live data before being used for real.

[Zope] Objects loosing persistency
I have a Plone web app where the users are complaining that they can create objects, edit titles etc. But when they return to the objects a little later, they are gone. The same behaviour as when an object doesn't have its _p_changed = 1 set, it seems to me. So I just wonder if anybody knows what can be causing this? It is not programming error as it happens with stable products. It is only this particular site that has the problem. There are reletively many objects in the system, so I suspect it to be some kind of conflict with a lot of reads blocking for the writing to the ZODB? -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science ___ 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 )

I have created a product to redirect authenticated users to HTTPS, using a pre-traversal hook. In the hook, it turned out that URL is the url to the folder with the pre-traversal hook, and not the requested url. I think that URL is modified during the traversal process, so that it contains the url for the current object. Only when the last object is reached does URL contain the full requested url, and is it equal to ACTUAL_URL.
