Zope stops responding
by Mark Gibson 25 Oct '04

25 Oct '04

Zope 2.7.2 Plone 2 python2.3.4 Linux After running normally for a while, zope will stop responding. 'top' shows no activity on the zope threads. There is nothing in the error log. zopectl stop doesn't work, and a 'kill -9' must be used to kill the process so that it can be started back up. A google search reveals that others have had the same problem, but I did not come across an explanation or solution. Any ideas? -- Mark Gibson <mark(a)kaivo.com>

Passing "error" variable to another page template?
by Jason Leach 25 Oct '04

25 Oct '04

You can put it in 'options'. If you were in a PythonScropt you could: container.myZPT(some_error='Warning. Bla bla') Then in the ZPT: <span tal:content="options/some_error"></span> On Sat, 23 Oct 2004 12:00:04 -0400 (EDT), zope-request(a)zope.org <zope-request(a)zope.org> wrote: > Send Zope mailing list submissions to > zope(a)zope.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://mail.zope.org/mailman/listinfo/zope > or, via email, send a message with subject or body 'help' to > zope-request(a)zope.org > > You can reach the person managing the list at > zope-owner(a)zope.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Zope digest..." > > Today's Topics: > > 1.

Zope Community Evaluations
by Stephan Richter 25 Oct '04

25 Oct '04

Hello everyone, Katrin Wodzicki, a psychology student at the University of Jena, is conducting a Zope Community evaluation as part of her thesis. The questionnaire tries to explore the satisfaction and motivation behind Zope community members of all kinds. She will make the results available to the community and I think that they can help us understand the need of the community better. So please take a moment and answer the questionnaire at http://evaluation.gocept.com. Thanks for your support! Regards, Stephan -- Stephan Richter CBU Physics & Chemistry (B.S.) / Tufts Physics (Ph.D. student) Web2k - Web Software Design, Development and Training

Passing "error" variable to another page template?
by Kirk Strauser 25 Oct '04

25 Oct '04

I'd like to use a tal:on-error clause to render an error message that includes the contents of the "error" variable, and I'm at a loss as to how to go about that. I guess that a more general form of the question would be, how do I pass variables to page templates? -- Kirk Strauser The Day Companies

ZODB scalability in in large Zope deployments
by Jeff Rodriguez 23 Oct '04

23 Oct '04

I'm planning on using Plone and Zope for our company intranet. If there's one thing I've learned working at my company it's that we will push whatever the product is to it's absolute limit and then ask for more. Which makes me wonder, how does ZODB scale in massive deployments? I'm not really concerned with the number of hits so much as ZODB's ability to handle: 1. Large quantities of large objects 2. Small quantities of very large objects. 3. Large quantities of small objects. I can really forsee millions of objects with sizes ranging from a couple kilobytes to hundreds of megabytes. Anyone with experience in this type of setting please let me know as I am very interested in the difficulties, compromises, or praise you have for/with ZODB/ZOPE/Plone. Thank you, Jeff Rodriguez

Hi, I've just seen that in my Zope 2.7.2 installation Copy or move permissions are granted to anonymous users by default in the zope security settings. Why that? Kai
