Why is the file locked to the ZMI when I use custom_zodb.py?

an idea for zopewiki

Exporting Plone objects to Zope CMF
by Kanealii, Priam Mr KRS 29 Apr '05

29 Apr '05

Dear Zope-list, Running with Zope 2.7.5 Plone 2.0.5.. What "nice" method exists, if any, to export CMF-ish things like documents, events, and news items from Plone to ZopeCMF? (Or, what search terms may have escaped me?) Ideally, I'd like to be able to export folders in Plone and import them to Zope CMF such that Plone-ized CMF items were magically de-Ploned (and allow for sufficiently Plone-ized things to remain broken). Unfortunately, importing folders or most other objects raises a Copy Error:: "Object *broken* does not support this operation." I'm just wondering if there are options to porting content by hand ..which will be less than a day's work in this case (we're just getting started). In absence of a nice method, I'm curious what methods others may have applied in a similar situation. Mahalo, Priam

Zope large-file-threshold
by Joern Wallstabe 29 Apr '05

29 Apr '05

Hello, i'm trying to upload a large file (90Mb) via a web form. While doing so I expect Zope writing a temporary file into /tmp because the request is large than 'large-file-threshold' in zope.conf. But it all gets loaded into memory and no file ist created in /tmp. Am I missing something ? My Setup ist Zope-2.7.5 and Python 2.3.5 Regards Joern

Corrupt Data.fs
by Michael Kaplan 29 Apr '05

29 Apr '05

Hi, I just found out that my Data.fs is corrupt. Zope is still running, and restarting but I'm getting POSKeyErrors if a want to see folder contents and so on. I tried to follow the advice in http://www.zopelabs.com/cookbook/1095965033 (I use Zope-2.7.4) but end up with >>> obj=root.unrestrictedTraverse('/folder') Traceback (most recent call last): File "<stdin>", line 1, in ? NameError: name 'root' is not defined what's wrong here? Therefore I used fsrefs.py and got information like oid 0x030571 Products.CMFCore.ActionInformation.ActionInformation last updated: 2005-03-14 08:20:34.643177, tid=0x35BE85493CF9666L refers to invalid object: oid 0x0304fa object creation was undone: 'Products.CMFCore.Expression.Expression' For this oid I get > python Python 2.4 (#1, Jan 14 2005, 00:24:33) [GCC 2.95.3 20010315 (release)] on sunos5 Type "help", "copyright", "credits" or "license" for more information. >>> from Zope.Startup.run import configure;configure('/etc/zope.conf') >>> from Zope import app >>> from ZODB.utils import p64 >>> from ZODB import POSException >>> app = app() >>> obj = app._p_jar[p64(0x030571)] >>> print obj.getId() view >>> print obj.bobobase_modification_time() 2005/03/14 09:20:34.643 GMT+1 >>> print obj.meta_type simple item >>> print obj.__ac_local_roles__ None Could anybody tell me, how I can delete this object from Data.fs? Will obj.manage_delObjects(id) do the job for me? What parameters do I have to give to the programm? Thanks a lot in advance Michael

Unable to login to zope management interface on Ubuntu
by Vishwas Narendra 28 Apr '05

28 Apr '05

Hi, I'm running Ubuntu (warty). I just installed zope 2.6.4-1.1 through synaptic. I created a user with the "zpasswd inituser" command. I could connect to the zope server on port 9673. The zope quick start page comes up. When I click on the management interface link, I'm asked to enter the username and password. Even after I enter it correctly (the same values that I entered through zpasswd), I keep getting the same dialog box over and over again and I'm not able to proceed beyond this stage. Where am I going wrong? Vishwas.

Session Variable Error
by Asad Habib 28 Apr '05

28 Apr '05

I have a session variable called 'undergraduateProjectsDirected' that I declare using the following syntax: <dtml-call "REQUEST.SESSION.set('undergradProjectsDirected', [ ])"> When I try to append items to this list variable, I get the following error: AttributeError: 'NoneType' object has no attribute 'append' I know for a fact that this variable exists since flushing the SESSION attribute of the REQUEST variable using <dtml-var "REQUEST.SESSION"> yields its name and shows that it is initially empty. I am using the following statement to append items: <dtml-call "(REQUEST.SESSION.get('undergraduateProjectsDirected')).append([student_name, description])"> The strange thing is that when I change the name of this variable to 'undergradProjectsDirected', the error does not occur anymore. Has anyone experienced something similar? I think a variable with the same name exists (perhaps I created one in another one of my intranet applications) and Zope is referring to the old copy instead of the newly created one. I tried flushing the transient object container as well but it did not make a difference. Any help would be greatly appreciated. Thank you. - Asad
