Conflict error
by Ulrich Wisser 10 Nov '04

10 Nov '04

Hello, yes I have read the Zope book about SESSIONs and the conflict errors. But the book says it should almost never happen, it happens constantly at my site (~10 users). I use Zope sessions. Any suggestions? I have sold in Zope to my boss, so my and Zopes reputation is on the line. Please help!!!

zope startup script
by John Poltorak 10 Nov '04

10 Nov '04

When I originally installed Zope 2.6.2 a startup script was created in /etc/init.d, although I don't recall how it got created. Does v2.7.3 create a new version of this file when running make install? If not, how is it created? -- John

zope2.6.4/python2.2 doesn't restart after crash, with python2.1 it does
by Jonas Meurer 10 Nov '04

10 Nov '04

hello, we encounterd some problems with our zope 2.6.4 installation. if we put an instance under heavy load, it crashes and thus - according to event.log) tries to restart the server. zope 2.6.4 compiled with python2.1 does this very well, and is back after max. 1 minute. zope 2.6.4 compiled with python2.2 doesn't do this, in other words it fails. event.log tells me something like other processes are already accessing and thus locking the Data.fs. is this a known issue, are workarounds available? normally we use the debian packages for zope 2.6.4 which run zope with python2.2, but we just installed a source installation of zope 2.6.4 with python2.1 for debugging issues, and i realized this bug in python2.2 usage. i thought that zope 2.6.4 has official python2.2 suppport? bye jonas

ZOPE_HOME
by John Poltorak 10 Nov '04

10 Nov '04

How does Zope (v2.6.2) establish what constitutes ZOPE_HOME ? I don't see any reference for this variable in /etc/zope and wondered what I would need to change if I wanted to move Zope to a different location. -- John

by Stephan Richter 09 Nov '04

09 Nov '04

Hello everyone, on popular demand from a couple of people we have decided to create a new Zope 3 Users mailing list that will serve to answer your questions about Zope 3. The Zope 3 developers have made a commitment to answer your questions in a timely manner. We hope that this way the generic Zope and Zope3-Dev mailing list will be disburdened from user-related questions. You can subscribe to the mailing list at: http://mail.zope.org/mailman/listinfo/zope3-users Regards, Stephan -- Stephan Richter CBU Physics & Chemistry (B.S.) / Tufts Physics (Ph.D. student) Web2k - Web Software Design, Development and Training

adding properties trough pythonscript
by rv000299 09 Nov '04

09 Nov '04

Hi all, I have some problems adding properties trough a python script def publishcontainer(container,path): ov=map(lambda x:(x.id,x), container.objectValues()) ov.sort() for (oid,obj) in ov: if not (hasattr(obj,"isPortalContent") or obj.isPrincipiaFolderish): continue id="" if hasattr(obj,"isPortalContent"): print "ID: ",path+"/"+str(obj.id) try: context.manage_addProperty('prop', 0, 'boolean') print "prop added<br>" except: print "adding prop to",str(obj.id),"failed<br>" if hasattr(obj,"objectValues"): print publishcontainer(obj,path+"/"+str(obj.id)) return printed The problem is not getting the property added, it does, but editing it afterwards in the ZMI is impossible. When I hit the Properties tab of the item, the newly added property is not on the page. However when I call the prop with a dtml-var it is rendered. I'm at a loss here. Can someone help me out?

RPCAuth again
by David Cake 09 Nov '04

09 Nov '04

OK, I asked previously about installing RPCAuth on Debian. I got no useful responses (thanks to Tres Seaver for passing my message on to the author, but they didn't get back to me). There is basically no documentation on this product, couldn't get it to install on either zope 2.7 on Debian (apparently stops entire zope instance from working) or Mac OS X (just never shows up - its in /Applications/Plone2/Sites/Default/Products/ along with other products, but can't see any evidence Zope knows its there). So, anyone managed to install this product, or know how to debug installation problems of this kind? I'm having a very mixed experience with Zope/Plone - I either get a lot done in a short time, or things don't work and I get stopped dead, with very little documentation or help as to how to proceed. Regards David

Re: Application Design and Photos
by Gregor Melhorn 09 Nov '04

09 Nov '04

Hello zope-users, thank you very much for your suggestions! I thought about it for a while, and the following solution came to my mind :-) First: Speed is critical to the site, since there may be several thousand users online at the same time. What about using the extImage Product, letting apache serve the content from an external image repository? So Zope only serves image urls. This should be way faster than letting serve Zope the images all by itself. For security, I thought of creating a separate directory for each user containing the user's photos. Directorys are configured to not be listable by anonymous users via apache. Every filename is a random string with at least 30 characters, so guessing the files should be impossible. For added security: I don't know if there is some kind of apache rule that allows locking out ips that tried to guess files, therefore generating a lot of 404s. Security could further be improved by checking the referrer in the rewrite rule, which is used by extImage. Also it would be possible to set a cookie at the gallery page, and checking the cookie in a rewrite rule. This would prevent authenticated users from linking directly to the images (and therefore allowing unauthorized access). Not 100% secure, but should be difficult for everyone that doesn't know how to fake a cookie and modify his referrer = the average user). What do you think about that solution? Thanks for your help!!! Gregor
