Key Error
by Asad Habib 08 Jan '04

08 Jan '04

Hello. Zope is flagging me with a 'Key Error' when I try to execute the following code. <dtml-let numberDegrees="REQUEST.get('numberDegrees')"> <dtml-in "_.range(0, _.int(numberDegrees), 1)"> <dtml-let degree_description="REQUEST.form['degree_description_<dtml-var sequence-item>']"> </dtml-let> </dtml-in> </dtml-let> The variables designated by degree_description_<dtml-var sequence-item> are being successfully passed into this DTML method from a DTML document. However, I don't know any other way of accessing them within the loop. Any help would be greatly appreciated. Thanks. - Asad

Mappings to folders inside localfs objects aren't accepted
by Josef Meile 08 Jan '04

08 Jan '04

Hi, I have a VirtualHostMonster on the root of my zope server (version 2.6.1). On the past (on 2.5.1 I think), I added some mappings to folders inside localfs objects and it worked. Now, I'm trying to add new mappings and the problem is that the previous mappings that I made become invalid and are followed by the text: "#! Path must lead to an Object Manager" I found that the problem is the following validation in the VirtualHostMonster.py file: -- if not getattr(ob.aq_base, 'isAnObjectManager', 0): ---- raise 'LineError', ('Path must lead to ' ---- 'an Object Manager') I removed it, restarted zope, and it worked. Does this also happen with the latest versions of zope? is this a bug? Thanks, Josef

Thanks to PieterB for this url: Following the procedure at http://www.zettai.net/Members/george/python213FreeBSDPlone.blog/view seems to have improved the situation. Time will tell I couldn't find the patched thread_pthread.h at plone.org so skipped that step. Jim.

communication between Zope's now broken
by Dennis Allison 08 Jan '04

08 Jan '04

I have one complex of Zopes that have one adminsistration site and a collection of productions sites. The administration site invokes actions on in the production sites through the web using a redirect, and control is returned to the administrative site by a redirect back. It's worked pretty well. I've now cloned the site--and all the inter-zope communications no long work. If I invoke them through a browser URL, they work, but programmatically they do not. I suspect a security/permissions problem, but I've not been able to identify it. Any suggestions appreciated.

RE: [Zope] LDAPUserFolder and roles assignements Problem

The LDAPUserFolder is not at fault but maybe your LDAP Server. If you have an Active Directoy LDAP Server, you have a limit of 1000 Objects, which you can increase.

LDAPUserFolder and roles assignements Problem
by Gabriela LÃ³pez Ruiz 08 Jan '04

08 Jan '04

Hi people, I instantiated a Group User Folder object for my Zope+Plone app. and configured it to take users from an LDAP server in order to get users id and passwords validated. The underlying users source is an LDAPUserFolder object which cannot retrieve the entire users list ( LDAPUserFolder is limited in results size!). In this way, I'm not able to assign roles to my users in the ZMI since I don't get the user list! I also dont have the Comma separated list of special additional role userid's and Comma separated list of additional roles for special userid's I used to have in a LDAPAdapter object for instance. Has anybody found a way to assign roles to LDAP-based user names? Thanks in advance!

Multiple threads using Apache Rewrite
by jim＠jaydublu.com 08 Jan '04

08 Jan '04

We have a machine (FreeBSD) set up running Apache to dish up 'normal' websites on port 80, and we have been developing a couple of Zope based Intranet type sites, so we have ZServer running on its default port of 8080. We're using Apache mod-rewrite to transaprently proxy Zope request to the ZServer. All is sweet. That is until a request that ties ZServer up for a period of time is closely followed by a second request - the result from Apache is a 'proxy error' - i.e. there was no server visible to respond to the second proxy request. Running ps -aux only ever shows two Zope processes, no matter how hard one is working. Isn't there supposed to be a monitor process running which forks new processes when existing ones get busy, like Apache does? Both Apache and Zope were installed from FreeBSD Ports using default startup scripts. Advice gratefully received. Jim Whiteside.

Can't use FTP to upload file
by Albert Lee.K.W 08 Jan '04

08 Jan '04

Hi, I am using WS-FTP to upload files, however, I can login successful , can't list, upload and download the files. I have already add -f 9089 in the start script. And enable the ftp access privileges in the ZMI. I have a router but I allow the TCP port 9089 in to my ZServer. How can I solve the problem?? There is the log of FTP : USER admin 331 Password required. PASS (hidden) 230 Login successful. PWD 257 "/" is the current directory.

Sessiondata in SQL
by Heimo Laukkanen 08 Jan '04

08 Jan '04

Hi ya all, I wondered about integration applications in php better with applications in Zope and thought about even handing over sessiondata via sql. What is the contemporary way to have sessiondata in SQL RDBMS and are the drawbacks in it too much to even think about it - compared to using the ram based sessiondata? I tried to google but did not find that much information about whether people had written their own sessiondatamanagers or sessiondata storages to do this - hence the question. -huima

Strange errors preventing our Zope instance from starting

Hello, We are running a Zope 2.5.1 (yes, I know, old) version on one of our servers and yesterday we started getting these errors (quite a lot of them) on the error log: 2004-01-05T11:06:05 ERROR(200) ZODB Couldn't load state for '\x00\x00\x00\x00\x00y0s' Traceback (innermost last): File /var/Zope/Zope-2.5.1-src/lib/python/ZODB/Connection.py, line 447, in setstate File /var/Zope/Zope-2.5.1-src/lib/python/ZODB/FileStorage.py, line 582, in load (Object: /var/Zope/instances/cc251/var/Data.fs) File /var/Zope/Zope-2.5.1-src/lib/python/ZODB/FileStorage.py, line 557, in _load (Object: /var/Zope/instances/cc251/var/Data.fs) POSKeyError: 0000000000793073 And then this: 2004-01-06T06:05:06 PROBLEM(100) ZODB FS FS21 warn: /var/Zope/instances/cc251/var/Data.fs truncated, possib ly due to damaged records at 2137747449 ------ 2004-01-06T06:05:06 PROBLEM(100) ZODB FS FS21 warn: Writing truncated data from /var/Zope/instances/cc251/v ar/Data.fs to /var/Zope/instances/cc251/var/Data.fs.tr0 ------ [ ... more logs in here ... ] ------ 2004-01-06T06:24:52 PROBLEM(100) OFS.Application Duplicate Product name After loading Product 'SiteAccess' from '/var/Zope/instances/cc251/Products', I skipped the one in '/var/Zope/Zope-2.5.1-src/lib/python/Products'. ------ 2004-01-06T06:24:53 PANIC(300) z2 Startup exception Traceback (innermost last): File /var/Zope/Zope-2.5.1-src/z2.py, line 571, in ?
