Empty Products folder with Zope 2.13.1
by Stefan Loidl 13 Dec '10

13 Dec '10

Hi, I've installed Zope 2.13.1 with easy_install and python 2.6.6 on SLES 11.1, but the Products folder in the ZMI is empty and there's no 'Help!' link on any page. Same result with python 2.7.1. Is this like it is expected to be or is this a bug? There's no error message in the event log, but during installation I've seen these error messages: ... Searching for RestrictedPython Reading http://download.zope.org/Zope2/index/2.13.1/RestrictedPython/ Best match: RestrictedPython 3.6.0 Downloading http://pypi.python.org/packages/source/R/RestrictedPython/RestrictedPython-… Processing RestrictedPython-3.6.0.zip Running RestrictedPython-3.6.0/setup.py -q bdist_egg --dist-dir /tmp/easy_install-oRxtry/RestrictedPython-3.6.0/egg-dist-tmp-0A0PjW SyntaxError: ('invalid syntax', ('build/bdist.linux-x86_64/egg/RestrictedPython/tests/before_and_after27.py', 30, 17, ' x= {y: y for y in whatever if y}\n')) SyntaxError: ('invalid syntax', ('build/bdist.linux-x86_64/egg/RestrictedPython/tests/security_in_syntax27.py', 6, 13, ' {y: y for _restricted_name in x}\n')) SyntaxError: ('invalid syntax', ('/home/ndu/zope2.13.1/lib/python2.6/site-packages/RestrictedPython-3.6.0-py2.6.egg/RestrictedPython/tests/before_and_after27.py', 30, 17,' x = {y: y for y in whatever if y}\n')) SyntaxError: ('invalid syntax', ('/home/ndu/zope2.13.1/lib/python2.6/site-packages/RestrictedPython-3.6.0-py2.6.egg/RestrictedPython/tests/security_in_syntax27.py', 6, 13,' {y: y for _restricted_name in x}\n')) Adding RestrictedPython 3.6.0 to easy-install.pth file ... Any hints where the problem could be? Am I missing something? I don't see this problem with Zope 2.12.14 (there are products in the Products folder and the 'Help!' links exist). Many thanks, Stefan

Question about Upgrading Zope and OS X Server
by Dan Gaibel 09 Dec '10

09 Dec '10

Greetings, I have recently inherited the responsibility of supporting a fairly complex web server running Zope 2.8.6 on Python 2.3.5. This configuration is currently on a Linux (Fedora Core) server and I would like very much to migrate to OS X Server Snow Leopard. It also seems to me that I should consider upgrading Zope to a more current release while I'm at it. We heavily use MySQL and associated products, LocalFS, and the Python Imagining Library. We have a variety of ZClass homegrown products as well. I know that I'm in for a headache no matter what, but I wonder if any of you folks could point me in the right direction or offer advice on the situation. Is it crazy to jump from 2.8.6 to 2.12? Does anyone use OS X Server for Zope? Is this migration a mistake? Any pitfalls I should be looking out for? Many thanks, Dan

Openflow_ZPygresqlDA_products_broken_on_ZMI

Hi, Can I install ZPygresqlDA without uninstalling ZPsycopgDA on the same m/c? Will it work properly? If it works properly I will install ZPygresqlDA-0.0.3 on dev Linux box & again import my source code & check whether it still appears broken? Please help me so that I can progress accordingly. If this doesn't work I will install all the products on dev with the same version as the products on live as suggested by you. Thanks a Lot in Advance!

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
by Smita Kamdar 07 Dec '10

07 Dec '10

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

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?

"double opt-in" or "opt-in with confirmation".
by Brian Sullivan 30 Nov '10

30 Nov '10

I am looking for a strategy or samples (or even just a hint as to the best process) to create an email opt-in strategy in Zope. I am thinking that what you do is use some sort of hash or unique id creation mechanism (based on the email address, time or something else). Based on what I am seeing -- some sort of MD5(not totally sure what that means but I understand there are Python supplied functions to generate it) hash of a combination of the email address and date/time stored and then sent to the user should guarantee that it is unique, can't be auto generated by some bot and should allow verification on http access using the hash in the url? All the potential solutions I am seeing use Python 2.5 + -- the version of Zope I am using is based on Python 2.4.4. Anybody have any ideas or have implemented something like this?
