Memory Leak Debugging
by Jonathan Bowlas 28 Feb '06

28 Feb '06

Hi All, We're having serious problems with performance running Silva CMS on Zope 2.7.8-final, python 2.3.5, linux2 set up on a machine with 2.5GB RAM. There are currently only about 65 users and around 2000 documents in the CMS but it seems to run for a week, then the RAM fills up and crashes so we have to restart the server manually. The Zope logs aren't much help as I enquired on the Zope list and their response was we need more RAM. But surely 2.5GB is enough. I've also checked Control_Panel/DebugInfo for any refcounts with significant jumps and Products.Silva.Image.Image seems to be the culprit: 11.32am 11.36am Products.Silva.Image.Image 56203 58153 +1950 Acquisition.ImplicitAcquirerWrapper 44825 45151 +326 So we've tried to figure out which kind of request triggers these refcount jumps by creating a separate instance with a very small ZODB Cache (so it gets filled up soon), and clicked around a little, watching the refcounts but we cannot seem to replicate it. So basically this is a plea for help from an expert Zope debugger who can assist us in finding the source of the problem so we can resolve it. Or alternatively someone who can give us a set of instructions that we can follow that will enable us to locate the problem, I've googled it and there are no clear answers. FYI we have the following products installed on our Zope instance.

Dynamic dictionary keys?
by Andrew Hedges 28 Feb '06

28 Feb '06

Allow me to preface this by saying I am a complete newbie to Zope (I prefer to think of it as beginner's mind...). What I am attempting to do is dynamically add items to a dictionary, but Zope complains "keyword can't be an expression". Here's the reduced case of my code: <dtml-let eventsDict="{}"> <dtml-let calstart="somestring"> <dtml-call "REQUEST.set(eventsDict[calstart]=id)"> </dtml-let> </dtml-let> This kind of construct *seems* perfectly reasonable, yet it doesn't work. Any suggestions? Other possible ways of doing the same thing? Thanks! -Andrew ----- Andrew Hedges, Clearwired Web Services andrew(a)clearwired.com / http://clearwired.com/

Packing data.fs programmatically
by Jonathan Cleaver 27 Feb '06

27 Feb '06

I am using the following module to pack my data.fs programmatically before a backup is made. This was largely taken out of the Zopelabs cookbook - thanks! ------------------------ def packZODB(): try: import os, sys os.chdir("/path/to/Zope/python") sys.path+=['/path/to/Zope/python/was/required/to/load/Zope/module'] import Zope Zope.configure("/path/to/zope.conf") app = Zope.app() app.Control_Panel.Database.manage_pack(days=0) get_transaction().commit() app._p_jar.close() return 1 except Exception, inst: for arg in inst.args: print "Oh dear! %s" % arg -------------------------- Now for the wierd bit. I successfully ran the code that went into this module line-by-line in the Python interpreter. The data.fs was beautifully packed. However, when I run this script from the command line (through another script that acts as a hook) the line "app = Zope.app()" fails with the error "No such file or directory". Now I am confused, coz the code lines that you would expect to fail if either of the required paths were not correct ran quite happily. I am running Python 2.3.5 and Zope 2.7. Does anyone have any thoughts? Cheers Jonathan Cleaver

Dates off by one day
by Kevin Carlson 27 Feb '06

27 Feb '06

Recently moved to a new server farm and am having a problem with dates from MySQL that are rendered using strftime. The date in MySQL is correct (e.g. 2005-01-22) but if the date is rendered with strftime the date displayed is one day earlier (e.g., 2005-01-21). MySQL and Zope are on separate servers as they were before the switch to the new servers but this didn't happen in the old environment. Anyone have any thoughts on this? Thanks, Kevin

Zope scheduling problem
by Nicholas Watmough 27 Feb '06

27 Feb '06

Hello, I'm not sure if this is the correct forum for my question. I'm running Zope 2.9.0 (though I've tried it on 2.8.5, with the same problem). I have a Python script in a Zope folder that checks a specified email address, packages all the emails and attachments, and adds them into a PloneArticle running on a Plone site. It finds the correct PloneArticle to add the item into, by doing a ZCatalog search (on the Plone portal_catalog). This works properly when I run the script myself. The user I run this as has the Manager role. I've set a proxy for the script so it runs as a Manager. However, when I set a ZopeScheduler to run this script, I get an error where the ZCatalog doesn't find any results when I search for the PloneArticle instance. Now the article I am searching for is catalogued, so I'm not sure why this is happening. This may be a problem with ZopeScheduler, or with Plone's catalog. Not sure which. Any assistance would be appreciated. Nick

Using ReStructuredText instead of StructuredDocument inside ZPT
by John Schinnerer 26 Feb '06

26 Feb '06

Hello, I have been using the Structured Document (SD) product with page templates (to provide some content sections that a client can edit using structured text). Now I would like to use ReStructuredText Document (RSTD) instead of SD. I have been using code like this in a page template to render the content of a SD within the page template: ... <div metal:fill-slot="pagebody"> <p tal:content="structure container/client_content/vision_statement"> Vision Statement </p> </div>  ... ...where vision_statement is a SD object. I expected that this would work the same if vision_statement were a RSTD object...however it does not. What displays is only the unrendered, plain text content of the RSTD. Can I use a RSTD object in the same way I have been using a SD? If so, how do I get it to render? This is on zope 2.7.5 with the ZReST that comes "built in." A RSTD called directly (instead of inside a ZPT as above) renders as expected. thanks, John S. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
