Data.fs.lock => shouldn't be there?
by Serge Renfer 23 Mar '05

23 Mar '05

Hello all, Me again! Always with Zope 2.7.4 on Solaris 9. I've detected that I had a lock on the Data.fs (more than 2Gb) file (Data.fs.lock) for several days (Data.fs hadn't changed its modification date for days) and the Data.fs.tmp was growing over 11Mb! I removed the lock (rm Data.fs.lock), but it didn't change anything to this situation. After an export of all the sensible data, I did a restart! It wouldn't restart! I moved the Data.fs.index out the "var", and restarted => it did restart, but all the changes from the moment Data.fs had been locked had gone (probably what was in the Data.fs.tmp => since it got back to 0k) It takes a little longer to reboot (since it has to remake its index), but the problem is here again: there is again a Data.fs.lock file in the "var" directory ! => I can assume that it has to be there during reboot while it's making its index, but then it should desapear, shouldn't it? Or is it a lock from zope itself and it is always there? 1) At some time, my zope instance get blocked outside the Data.fs ! 2) It seems that the index does not keep up, as it generates errors while restarting ! Is there a link between these two situations? I cannot figure what could lock out zope from the Data.fs ? Is this Data.fs too big (not far from 3 Gb => in fact it was more than 3Gb but I packed it before restarting it => it didn't affect the size of the Data.fs.tmp though, that remained over 11Mb) ? Thank you for your reading of my problems! serge

Running as an incorrect use can cause all sorts of problems, so lets say "yes" for the sake of argument ;-) > The error_log object in the zope root has no entries, and the error_log > object in the plone root has since been overwritten with new exceptions. > Both weren't set up to copy exceptions to the event log, I've turned > this on to log these errors. Good :-) cheers, Chris

Where to sys.setcheckinterval() for plone/zope? (was: Re: [Zope] Re: SMP and Zope.

For a normal plone site: Where would it get picked up? I added it to the beginning of $SOFTWARE_HOME/Zope/Startup/zopectl.py (the script called by "zopectl start"). However, the new checkinterval ist not passed on to the rest. Do I have to set this at the beginning of each script? Where would be a suitable place/file to add this setting?

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_
