on-the-fly storage/mountpoint setup or reload configuration
by Jordi Llonch 21 Oct '08

21 Oct '08

Hello, I want to know if there's a way to reload configuration of a Zope2 zeo and instance without having to stop service. zopectl command has a reload argument but is not working for me at least from 2.7.8 to 2.11.1 versions. Theres a bug reported on Zope Collector. My goal is create a zeo filestorage without having to reload the zeo server (has other working instances). And also, reload the zope instance in order to mount the created filestorage in zeo via a mountpoint. Thanks in advance, Jordi

weird page template errors...
by Chris Withers 21 Oct '08

21 Oct '08

Hey All, Still getting the odd weird error following my move to Zope 2.11. The following are currently very confusing: Module Products.PageTemplates.ZopePageTemplate, line 330, in _exec <snip> Module zope.pagetemplate.pagetemplate, line 115, in pt_render - Warning: Macro expansion failed - Warning: zope.tal.taldefs.METALError: macro nesting limit (100) exceeded by u'template/macros/showbullet' Module zope.tal.talinterpreter, line 271, in __call__ <snip> Module zope.tal.talinterpreter, line 754, in do_insertStructure_tal UnicodeDecodeError: 'ascii' codec can't decode byte 0xa3 in position 114: ordinal not in range(128) So for starters, what's with the 2 errors? For second, I don't get this error when I view the url the error is associated with, so I'm guessing this is specific to something the browser is sending. Any clue as to why this page would render fine for me but obviously isn't for someone else? Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

analyse ZODBUtilities/space.py results
by JeanMichel FRANCOIS 21 Oct '08

21 Oct '08

Hi, I have a plone2.5 web site in production on zope2.9 with more than 100 000 objects. I would like to analyse the content of the zodb to optimize the web site, find problems and better understand the ZODB. So i have started using space.py script, and got the results in the joined csv file. BTrees.XX classes are the most important results. So i would like to understand what are those BTrees stuffs: BTrees._IOBTree.IOBucket BTrees._IIBTree.IISet BTrees._OIBTree.OIBucket BTrees._OOBTree.OOBTree BTrees._OOBTree.OOBucket BTrees._IIBTree.IIBucket BTrees._IIBTree.IITreeSet BTrees._IOBTree.IOBTree BTrees._IIBTree.IIBTree BTrees._OIBTree.OIBTree according to me, btrees are folders that support a large numbers of entries. why they are totalize 50% of the database (585MO of 1.3Go Data.fs) I have a Members folder that contains about 8500 folders, got something like 8500 btrees for a simple mail product (one per members), got the PLoneGazette product that store 1 btree folder, but not enough to make 50% of the database, or i have missed sth. Can anyone help me to understand those results ? -- JeanMichel FRANCOIS Makina Corpus

Zope failing to load causing 503 error
by rugbert 20 Oct '08

20 Oct '08

I migrated a server from one machine to another (using this thread: http://ubuntuforums.org/showthread.php?t=35087) and while most everything transferred over correctly (some permission settings didnt) apache isnt %100 working. There are two virtual host files, the default, and the mysite.test.com. and Mysite is using zope for all the web stuff. At first, apache would only server the default virtualhost file, but I disabled it and now I get a 503 error. Im assuming zope is failing to load correctly, how can I fix this? would it help to post my virtual host file? -- View this message in context: http://www.nabble.com/Zope-failing-to-load-causing-503-error-tp19860988p198… Sent from the Zope - General mailing list archive at Nabble.com.

Non-blocking long-running Zope tasks
by Pawel Lewicki 20 Oct '08

20 Oct '08

Hi, What would be the easiest way of managing long-term Zope tasks? I'm using a Plone-based application using a lot of SQL queries and I have a problem with hanging, probably because of ODBC driver - it hangs on timeouts (Windows). I have an idea to rewrite the core to delegate problematic tasks out of main Zope process. It would solve two problems at once. Long non-responding requests and hanging service. (I would check for query results by AJAX requests.) At the moment the most promising is zc.async. I would connect ZEO dispatchers and give back query results. Problem is that I don't need persistence for most of task results and I wonder if ZEO transactions are necessary for that king of processing? Any starting points to suggest? Paweł Lewicki

Five and editform
by Mark Gibson 17 Oct '08

17 Oct '08

I created a simple content type. I can create an object, but I can't call my view or edit form on it. If I try object/boring_editform or object/index.html I get a Not Found error. Here's what I have in my configure.zcml: --- <browser:editform schema="boring.interfaces.IBoring" for="boring.interfaces.IBoring" name="boring_editform" label="Edit Boring Folder" permission="boring.ManageBoring" /> <browser:page for="boring.interfaces.IBoring" name="index.html" template="view.pt" permission="zope2.View" menu="zmi_views" title="View"> </browser:page> --- What am I missing? Thanks, Mark

Zope 2.11.1-final MailHost Product
by Giampiero Benvenuti 17 Oct '08

17 Oct '08

To whom it may concern, Thanks so much for your good work and for adding the new feature (MailHost with asynchronous mode). I have just installed the new version of Zope (2.11.1) on my Mac to be able to use it. I did struggle a bit, though, because I didn't realize that in the method for sending email “mto” has to be a list and not a string, as it used to be. Is it correct? Maybe I'm wrong, but I couldn't find any indication for it in the documentation. It would be nice if you could add this, or clarify this point. One more little thing: in /MailHost/dtml/manageMailHost.dtml the two checkbox tags are not closed /> Thanks again and best regards, Giampiero
