Traversal and five
by Miles 03 Mar '09

03 Mar '09

Hi, In Zope 2.9.9, is there a way to register a traversal adapter and if so how? I've googled for examples, but haven't found anything pertinent. I'm not clear where to find the API for the adapter, and also if this is used in as old a zope as 2.9.9. Can anyone confirm? Thanks, Miles

Zope2 and XMLRPC methods
by Rowan Woodhouse 21 Feb '09

21 Feb '09

Hi, I'm having some trouble getting XML-RPC methods going on Zope2/Five. I've got the following in my configure.zcml: <configure xmlns="http://namespaces.zope.org/zope" xmlns:browser="http://namespaces.zope.org/browser" xmlns:five="http://namespaces.zope.org/five" xmlns:xmlrpc="http://namespaces.zope.org/xmlrpc"> <include package="zope.app.publisher.xmlrpc" file="meta.zcml" /> <include package="zope.app.security" file="meta.zcml" /> <xmlrpc:view for="MZCore.interface.IMZTag" methods="smeg" class="MZCore.MZTag.MZTag.MZTagXmlRpcInterface" permission="zope.Public" /> </configure> and MZTag.py has the following in it: from zope.app.publisher.xmlrpc import XMLRPCView class MZTagXmlRpcInterface(XMLRPCView): def smeg(self): """something """ return 'hello!' But when I try to access the method via XML-RPC as follows (where aaa is and object that implements IMZTag) >>> s = ServerProxy('http://admin:admin@192.168.69.135:9673/aaa') >>> s.smeg() I get an error back saying "Cannot locate object at: http://192.168.69.135:9673/aaa/smeg" I'm at a loss now as what to try next. If I change the method name in either the configure.zcml or python files I get an error back saying that the method cannot be found when the .zcml file is parsed so I know it is being included. Does anyone have any ideas? Thanks, Rowan

Come to the Zope Sprint @ PyCon 2009
by Lennart Regebro 20 Feb '09

20 Feb '09

There will be a Zope + Friends sprint @ PyCon 2009, to work on Zope and Zope-related technologies like Grok, Repoze, Deliverence etc. http://us.pycon.org/2009/sprints/projects/zope/ Because of the Repoze overlap with WSGI based frameworks we plan to work closely together with the WSGI/Pylons/TurboGears/Repoze sprint happening at the same time, so this will be a supercool webframwork sprint! Everyone is welcome! It is not necessary to sign up beforehand, but it is recommended for planning purposes. Either put your name on the wiki-page yourself, or mail me and I will add you. http://us.pycon.org/2009/sprints/projects/zope/ For general information on the sprints, see: http://us.pycon.org/2009/sprints/ or ask me. Help out / Learn / Have fun! -- Lennart Regebro http://regebro.wordpress.com/ +33 661 58 14 64

Weird "undefined symbol: PyUnicodeUCS{2|4}_AsEncodedString" errors
by Chris Withers 18 Feb '09

18 Feb '09

Hi All, I wonder if anyone has seen errors like these before... Scenario is as follows, two Zope instances and a zeo server all running from the debian zope2.9 packages. All the control scripts for these instances fail with the following error when used: Traceback (most recent call last): File "/usr/lib/zope2.9/lib/python/Zope2/Startup/zopectl.py", line 322, in ? main() ... File "/usr/lib/zope2.9/lib/python/persistent/__init__.py", line 19, in ? from cPersistence import Persistent, GHOST, UPTODATE, CHANGED, STICKY ImportError: /usr/lib/zope2.9/lib/python/persistent/cPersistence.so: undefined symbol: PyUnicodeUCS4_AsEncodedString However, when run as a cron job as follows: @daily /var/lib/zope2.9/instance/x/bin/zopectl run /var/lib/zope2.9/instance/x/Products/Stepper/run.py -q / jobs ...the control scripts behave properly and the stepper jobs get run. To solve the problem, I built python from source and installed the latest Zope 2.9 from source. Now, all the instances behave fine, except the above cron job now fails with the following: Traceback (most recent call last): File "/opt/Zope-2.9/lib/python/Zope2/Startup/zopectl.py", line 334, in ? exitstatus = main() ... File "/opt/Zope-2.9/lib/python/persistent/__init__.py", line 19, in ? from cPersistence import Persistent, GHOST, UPTODATE, CHANGED, STICKY ImportError: /opt/Zope-2.9/lib/python/persistent/cPersistence.so: undefined symbol: PyUnicodeUCS2_AsEncodedString So, the problem seems inverted now and the error is about UCS2 rather than UCS4. Anyone ever seen anything like this? What is that symbol and why would it be there when run from a shell and not there when run from cron? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Periodic task in a Zope 2 environment
by Marco Bizzarri 18 Feb '09

18 Feb '09

Hi all. A little of background, before. I need to run some tasks, inside a zope environment, in a periodic way. Even though I could resort to using cron and wget, I do not like the solution too much, also because it requires me to rely on something completly external to the application to schedule the task itsel (I need to update the cron to change how often a job is run... ). Now, I can see I can run a task using zopectl run + a script. My script would therefore be something like: while True: do something sleep(for sometime) of course, there are dozen of ways to write this in a better way, but that is not the problem. My problem is understanding if it is possible to run such a script via the zdaemon. Can anyone shred some light on this topic? Is there a better way to run such tasks in Zope 2 environments?

Stored Procedures Versus ZSQL Methods
by Remy Pinsonnault 17 Feb '09

17 Feb '09

Hello, We have a Zope application with thousands of Z SQL methods connected to an Oracle Database. Our DBA want us to develop our new applications using stored procedures called through external methods, instead of using directly Z SQL methods, for performance issues and memory usage. Do stored procedures will allow better performance? Thanks in advance Rémy

Moving an application from Zope 2.8 to Zope 2.11
by Marco Bizzarri 17 Feb '09

17 Feb '09

Hi all. Following the advices I received about upgrading the current release of Zope, I'm moving an application from Zope 2.8 to Zope 2.11. I've already solve some minor issues with other Products I have, but now I would like to know how to handle this: I'm using Localizer inside the application, and TranslationService Product to proviide i18n namespace to PageTemplates. However, I think TransationService should not be used anymore in Zope 2.11, as there should be some other way to handle this stuff. Can anyone provide pointers? Regards Marco -- Marco Bizzarri http://notenotturne.blogspot.com/ http://iliveinpisa.blogspot.com/
