Hi, Can I install ZPygresqlDA without uninstalling ZPsycopgDA on the same m/c? Will it work properly? Also please find attached the OpenFlow-1.1.0 .I had downloaded it from the following link - http://openflow.cvs.sourceforge.net/viewvc/openflow/ <http://openflow.cvs.sourceforge.net/viewvc/openflow/> as I could not find it on the site i.e. www.openflow.it <http://www.openflow.it/> Also, ZPsycopgDA is properly installed on my m/c & also appears installed in ZMI's Product list. Only in the imported source code, ZPygresqlDA connection object appears broken along with OpenFlow. Do I need to install any other product for zexp imports??

Re: [Zope] problem installing Openflow product of zope on LINUX

Hi Marco, I have already installed the following products on my dev RedHat LINUX m/c - 1) Zope-2.11.4 2) Python-2.4.4 3) Egenix-2.0.6 4) Postgresql-7.4.13 5) Psycopg-1.1.6 6) OpenFlow-1.1.0 & on the live m/c also all these products are installed with a mismatch in versions of the products. Only in case of Database Adapter instead of ZPsycopgDA, ZPygresqlDA is installed on live. But still when I import my project's source code (i.e. .zexp file) from live to dev m/c all the code is imported successfully except it gives errors in Pygresql_Database_Connection & OpenFlow. For Pygresql_Database_Connection & Openflow it gives error as 'This object from PygresqlDA product is broken' & 'This object from OpenFlow product is broken' respectively. Is the issue because of mismatch of PygresqlDA & PsycopgDA at live & dev respectively?? Thanks a Lot In Advance!

Openflow product is broken on ZMI
by Smita Kamdar 06 Dec '10

Hi, I just got OpenFlow1.1.0 downloaded. But didn't know the steps to install. But as I extracted Openflow source tar ball in Zope's lib/python/Products directory, it created .pyc files for instance.py, activity.py, openflow.py, process.py, transition.py & workitem.py. & so because of that I thought that openflow is installed. But after that I was not able to see that in the Products dir of Zope Management Interface screen. So after that I implemented the solution that u gave me in your last mail i.e. to change a line (from Products.PageTemplates.Expressions import getEngine, _SecureModuleImporter) in expression.py file. After doing this & restarting zope now I am able to see the openflow on ZMI. Thanks a Lot for Ur invaluable help. After all this, I imported my project's code from live server to the development server (Please note that now I am in the process of setting up development env set up). But after importing the entire project code from live to dev server, on ZMI for OpenFlow it is giving error as 'Openflow Product is broken', while on live server it works perfectly. Only after importing code on dev server ZMI it is showing this error.Pls note that I am importing my project code in binary form (i.e. in .zexp format). On LINUX dev server, I started zope as (./zopectl fg) while doing all the above stuff. It showed the below error - ------------------------------------------------------------------------ ------------------------------------------------------------------------ ------------------------------------------------------------------------ ------------------------------------------------------------------------ -------------------------------------- [test@test bin]$. /zopectl fg /opt/zope/bin/runzope -X debug-mode=on 2010-11-30 20:23:33 INFO ZServer HTTP server started at Tue Nov 30 20:23:33 2010 Hostname: 0.0.0.0 Port: 8080 2010-11-30 20:23:33 WARNING Init Class Products.openflow-engine.instance.instanc method 'History' 2010-11-30 20:23:33 WARNING Init Class Products.openflow-engine.instance.instanc method 'History' 2010-11-30 20:23:33 WARNING Init Class Products.openflow-engine.activity.activit method 'editActivity' 2010-11-30 20:23:33 WARNING Init Class Products.openflow-engine.transition.transent method 'editTransition' 2010-11-30 20:23:33 WARNING Init Class Products.openflow-engine.transition.transent method 'editTransition' 2010-11-30 20:23:33 WARNING Init Class Products.openflow-engine.process.process method 'Map' 2010-11-30 20:23:33 WARNING Init Class Products.openflow-engine.process.process method 'Map' /opt/zope/lib/python/OFS/Application.py:809: DeprecationWarning: __init__.py of mehods' attribute.

WebDAV lock in Zope 2.11.4
by Brian Sullivan 03 Dec '10

03 Dec '10

Somehow in testing use of ExternalEditor product I have set the WebDAV lock on a file. The problem is that the lock doesn't seem to appear in the list of locks from the Control Panel, nor does it clear on a restart. I am at loss -- how do I proceed? Is there anyway around this?
