Problem with Zodb connections pool
by Claudio Battaglino 14 Oct '09

14 Oct '09

Hi all, I've a system with Zope 2.8.8 that since some weeks is very slow. The python process keeps busy the CPU (98-99%) and the memory used by the process is growing up. Every day a script makes a pack of the ZODB and restarts Zope so the Data.fs size is stable (about 350MB). In the event.log I can see many of this warnings: 2009-10-14T11:59:14 WARNING ZODB.DB DB.open() has 8 open connections with a pool_size of 7 What does it mean? I can see also some of these messages: 2009-10-14T12:14:16 INFO ZODB.Conflict database conflict error... According to you, are the two messages related? Thank you very much claudio

Re: [Zope] [Zope-Annce] ZClasses resurrected
by Allen Schmidt Sr. 05 Oct '09

So...we are on 2.8.10 and our biggest app on our site is a ZClass based news object. How close will this provide functionality to just drop our data.fs into 2.12 and have those zclasses work? This is huge news!

Zope 2.12.0 released
by Andreas Jung 01 Oct '09

01 Oct '09

On behalf of the Zope 2 developers community I am pleased to announce the official release of Zope 2.12.0. Major changes: - Ships with ZODB 3.9 - Runs on top of Python 2.5 and 2.6 (no official support for Python 2.4, your mileage may vary) - Fully eggified - you install Zope 2.12 directly from PyPI using *easy_install* or *zc.buildout* - Lots of cleanup on the module level (e.g. ZClasses have gone forever - like it or not) - Ships with the Zope component library (aka Zope 3.4) - RESTified documentation in order to generate nice looking HTML/PDF documents using Sphinx - lots of other small details For more details, check: http://docs.zope.org/zope2/releases/2.12/WHATSNEW.html Release notes: http://docs.zope.org/zope2/releases/2.12/CHANGES.html Especially read the installation instructions since the installation process is different from all other Zope versions (because of the eggification process). Keep in mind that we do no longer provide the traditional all-in-one source tarball: http://docs.zope.org/zope2/releases/2.12/INSTALL.html The official Zope 2.12 project page on PyPI can be found here: http://pypi.python.org/pypi/Zope2/ If you have found a bug, please report it on Launchpad: https://bugs.launchpad.net/zope2/ I would like to thank all people having contributed to this release. Special thanks to Tres Seaver for his tireless efforts in fixing bugs and maintaining the Zope 2 codebase and Hanno Schlichting who worked hard and steadfast on the eggification of Zope 2 and on the cleanup of various dark corners of the Zope 2 codebase. In addition we launched the dedicated zope2.zope.org microsite today. This is one of the first steps for relaunching the Zope sites (including www.zope.org) asap.

zope2.zope.org launched
by Andreas Jung 01 Oct '09

01 Oct '09

I am pleased to announce the launch of a new website dedicated to the Zope 2 application server: zope2.zope.org This site gives the Zope 2 application a much better representation on the web (which was more than necessary after having lived for years with the current old www.zope.org site). zope2.zope.org is not a community site. You will not be able to register or upload personal content (use www.zope.org for the time being). We will publish content on request (events, news etc.) - please contact the webmaster in such a case. It took more than half a year in order to get this site done and I would like to thank the following people for their involvement in this project: - Alma Ong (Design) - Robert Rottermann and Gerhard Hug (implementation of the Plone theme) - Jens Vagelpohl (server setup, technical support, content review) - Matthew Wilkes (content review) - Sidnei da Silva (moving Zope 2 downloads to Launchpad) - Michael Haubenwaller (the Zope webmaster) Andreas Jung Zope 2 Release Manager

lost zope password
by Jel Coward 25 Sep '09

25 Sep '09

Hi I am new around here. If I am not in the right place then please feel free to point me elsewhere. I have a site running Plone. The admin/manager password for zope is lost. I followed the instructions here after googling a bit: http://quintagroup.com/services/support/tutorials/zope-access/ to create an emergency user (following the 2. How to create emergency Zope access user in your Zope instance, created with buildout, instructions) But I can't login with the login created for the emergency user I can see the 'access' file that is created, and I put it where the instructions indicate. * Plone 3.1.6 * CMF 2.1.1 * Zope (Zope 2.10.6-final, python 2.4.5, linux2) * Python 2.4.5 (#2, Jul 31 2008, 18:51:48) [GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] * PIL 1.1.6 Running on ubuntu server. I am using the port specified in zope.conf Any pointers would be gratefully received :) Thanks! -- Jel Coward

maintaining session variables using zeocluster
by nair rajiv 14 Sep '09

14 Sep '09

Hellol, We are using a zeocluster with six clients and use pound for load balancing betwwen them. However I am having problems using session variables. I think that session variables are maintained separately for each client i.e a value set to sesssion variable when pound sends a request to one client cannot be retreived when a request is sent to some other client. What can be done in such a situation ? Thanks in advance Rajiv Nair
