I'm thinking of taking the time to try a simple SQL based implementation, as well as one in ZODB.

Request time grows with memory size
by Gerhard Schmidt 27 Apr '09

27 Apr '09

HI, I've encounters a performance Problem with Zope. Some requests take very long time to process while others are served very fast. All request go for the URL. The time for the delayed Requests grows with the memory size of the Zope Process. It's direct proportional. I have generated a chart showing the request times and memory size of the Zope Process. The chart can be found at http://etustar.ze.tum.de/frontend.jpg Our watchdog system restarts the Zope Process when it reaches 7.3 Gig Memory. The physical memory of the server is 16 Gig and its only used for the zope Server. There are at least 7 Gig Memory free. As you can see most of the requests are delivered within 2 seconds but some take up to 12 seconds. The Requests monitored are the request of our watchdog system. These requests are send approximately every 20 sec. When I set the restart memory limit higher the request time of the delayed request continues to grows proportionally. This server is part of a pool of 19 Servers. All are connected to one ZEO server. All show the same effect. We observe the same effect with regular requests. Some are served at normal speed but some requests are delayed. Any idea what causes this effect and how to fix it.

How to move acl_users from Zope 2.7.8 to 2.10.7 ?
by Aleksey Tsalolikhin 25 Apr '09

25 Apr '09

Hi. I am migrating a Web application from Zope 2.7.8 to 2.10.7. I noticed the format of acl_users has changed (the format of acl_users' exported XML file is different). How do I migrate the contents of acl_users from Zope 2.7.8 to 2.10.7, please? Thanks, Aleksey -- Aleksey Tsalolikhin UNIX System Administrator "I get stuff done!" http://www.verticalsysadmin.com/ LinkedIn - http://www.linkedin.com/in/atsaloli

The history of Zope
by Garito 24 Apr '09

24 Apr '09

To Jim Fulton with the permission of the list: Did you read the Guido's The history of Python weblog? If you are not busy enought ;), will be so much interessant and useful for us to know the Zope history We win on empathy with the people who make it possible (and we need to win on this ;)) We win on general knowledge with Zope We win on don't repeat the same mistakes you do (I think this is a goal for you, isn't it?) ;) Thanks! -- Mis Cosas http://blogs.sistes.net/Garito Zope Smart Manager http://blogs.sistes.net/Garito/670

problem accessing object as anonymous
by robert rottermann 22 Apr '09

22 Apr '09

Hi there, I try to find out, why in an intranet accessing an object from a link sendt by email is not possible. situation: a user from a plone intranet sends a link to a dokument within the intranet to a colleague. if that colleague clicks on the link while *not logged* into the intranet she is presented with the *browser* login box repeatedly. entering the credential does not help. the error log shows that access to the document is forbidden for the document for the user Anonymous while debugging I found out, that the __roles__ property of a given document is a tuple of the form ('GroupMember', 'Guest', 'Manager', 'FolderManager', 'Owner') if I copy the same document to a vanilla plone site its __roles__ property is ['Anonymous', 'Manager', 'Reviewer', 'Manager', 'Anonymous'] I have the impression, that when 'Anonymous' is part of __roles__, access to the object is possible. without it, access fails. now my questions: is the assumption, that the failed acces is caused by the missing 'Anonymous' role in __roles__ correct? if yes: what controls the setting of __roles__ if not: what could be the reason of the fact, that users are not presented the cookieCrumbler-base plone login is not presented? thanks very much for your help robert

by Bobby 21 Apr '09

21 Apr '09

Hi, I can't compare a string (pid) to an integer (brand_id); what's is wrong with my code below? pid is being passed in the URL as &pid= , brand_id is an integer from a database table. Could someone help me with this so that I could make the if statement comparison work? Thanks. <dtml-in "getTable()"> <OPTION VALUE="<dtml-var brand_id>" <dtml-if expr="brand_id==pid">SELECTED </dtml-if> /> <dtml-var brand_name> </dtml-in getTable>

cache for python calls
by iarly selbir | ski0s 17 Apr '09

17 Apr '09

I'm doing a hard task, trying to improve maximum of possible performance to Zope/Plone server, I already installed CacheFu that improved so much performance, I saw on a blog about cache for Python calls but wasn't explained about your configuration or installation. there are any related product for zope to do it or something like that? The main question is improve a better performance to this server. Any tip/solution is welcome. Thanks in advance. Regards, - - iarly selbir | ski0s :wq!

No problem guy all test that I doing is on "test environment" xD, errors are acceptable, all problems solution are stored in my personal knowledge base heh Btw I'm reading about memoize installation I don't saw anything related to code changes Look: plone.memoize Installation ======================= * Create a file called ``plone.memoize-configure.zcml`` in the ``/path/to/instance/etc/package-includes`` directory. The file should only contain this:: <include package="plone.memoize" /> Regards, - - iarly selbir | ski0s :wq!
