Data Insert Problems
by Jay Zeemer 22 Mar '05

22 Mar '05

Hello all, I am currently running into an issue with an application I am working. I have a form, currently 5 fields but will soon grow to be much larger, and when I run 50 conncurrent users against it from Open STA. Of the 50 attempts I am seeing about 60% of them actually completed in the SQL database, I am seeing an error of: ZODB conflict error at /VirtualHostBase/http/server.domain.com:80/VirtualHostRoot/dir1//dir2/submit /processForm (27 conflicts since startup at 2005-03-21T13:33:44) Most of what I have found in digging is that data write intensive applications may have this issue, but I was wondering if anyone could recommend away around this? Could any one tell me what is happening that is causing this, the processForm object writes out to a SQL database, not to the ZODB?? Thanks for any and all help!! Jay

Cache flipping?
by Darian V Schramm 22 Mar '05

22 Mar '05

I'm getting many of these in my event.log 2005-03-15T10:17:56 INFO(0) ZEC:1-None-1 flipping cache files. new current = 1 The goes down, every few days with no errors, other than the one above. In one instance the site went down after an error in a page template. This code shows in the event log just prior to the site going down. <p tal:repeat="photo container/objectValues"> <img tal:replace="structure photo"> <span tal:replace="photo/title">title</span> <span tal:replace="photo/getDescription">Description</span> </p> It seems improbable that the site would go down because of an error in a page template.

shared/virtual hosting recommendations
by AM Thomas 22 Mar '05

22 Mar '05

Hi everybody, I'm looking for good, solid, somewhat helpful Zope hosting for my several very small customers (five main domains) and myself. I found the long list of hosting providers on the Zope.org site (at http://www.zope.org/Resources/ZSP/) but I was hoping for personal endorsements, or a pointer to personal endorsements. Now is the time to praise your hosting provider! Maybe this would be less annoying to people with actual coding/configuring/installing problems if you sent your response to me, then I compile and publish the responses. I'm completely willing to do this. Zettai.net looks promising; they'll serve up 5 domains for $240, 10 for $390, which is roughly (very roughly - I'm interested in quality here) the price range I'm looking for. However, I've been unable to find ratings/testimonials anywhere but on their own site. I did search the recent e-groups archives of this list for "hosting" (no hits). I've also looked at a couple of hosting ranking sites, but couldn't find anything specifically for Zope hosts (nor a way to search for them), and I'm not sure I really trust that kind of thing anyway. I thought about just managing my own co-located server, but frankly I don't enjoy dealing with the interface between my own systems and the rest of the world; I'd just like to have someone else configure the server and set up the system initially, as long as I can muck around on it when I want to add another feature. So, I don't necessarily need a FreeBSD jail setup, but I very much want to be able to set up / have set up for me: Plone, a few other products, and my ancient custom product that some of my sites are running (which I hope to improve upon). One other thing I've discovered is important to me: being able to send e-mail messages from the server that _aren't_ likely to be blocked as spam. That means that if the server is on spam / open relay blacklists, it could be a problem. If you've had issues like this one, I'd like to hear about it, but I may or may not include it in the compiled information. This is my best guess for where to post this question. I'd be happy to be directed elsewhere. Thanks! - AM

Zope page templates and access controls
by Matthew X. Economou 22 Mar '05

22 Mar '05

Hello, I have a brief question about Zope page templates and access controls. My page template was written for Plone (it is a portlet macro), but I believe my question applies to Zope in general. What is the best forum to ask these kinds of software development questions? Should I post to a Plone developers' mailing list first? In case this is the appropriate place to ask, my page template lists the contents of a folder and prints out links to those items: <h5 tal:content="here/title_or_id">Folder Name</h5> <div tal:repeat="item here/objectValues" tal:omit-tag=""> <div class="portletContent even" tal:condition="repeat/item/odd"> <a href="#odd" tal:attributes="href item/absolute_url" tal:content="item/title_or_id">Odd item title</a> </div> <div class="portletContent odd" tal:condition="repeat/item/even"> <a href="#even" tal:attributes="href item/absolute_url" tal:content="item/title_or_id">Even item title</a> </div> </div>  To call this template, one simply adds the name of this page template to the end of the URI, e.g. portal/path/portlet_folder_contents in the Plone site's left or right slots, or http://web.irtnog.org/legal/portlet_folder_contents in the browser. I don't want this page template to display anything if the user does not have rights to read the underlying folder or its contents, e.g. I use this list the contents of a folder to which only authenticated users should have access. Do I simply change the view permissions on the folder and contents themselves (that would be ideal) or on the Zope page template itself, or must I encode some permissions check in the body of the page template? Pointers to the relevant documentation would be greatly appreciated. I am in the midst of reading through the 2.7 edition of the Zope Book. Best wishes, Matthew -- "The challenge of a moral life is to do nothing that requires forgiveness." - Roger Ebert in his review of _The Woodsman_

I know that - I even mentioned it in my post, and it doesn't affect what is used in the access log. I think it should, or at least configurably should. I can't find any documentation on what you can put in the log's "format" directive apart from %(message)s, but this would seem to be the place to put it. Getting apache to log works well, but we are using squid for a proxy, and getting it to log is not so easy - at least not if you want the extra things in the detailed logs like reffering pages, browser types and user names. As there didn't seem to be any existing solutions we've had a look at zope's internals, and made a patch that logs the last address from the x-forwarded-for header, rather than the IP address of the proxy where available. I've attached it to this message. As zope is deployed behind a proxy probably 99% of the time, it seems like a good way to work. I've attached the patch below. Robert (Jamie) Munro
