Recovering corrupt XML Export files?
by Terry Hancock 25 Aug '02

25 Aug '02

Hi, I recently had some problems with my site involving CookieUserFolder, so I was trying to back it out. However, even after removing all CUF folders and the product, I still had cookie authentication coming up (apparently following the information in regular UserFolders (?)). Anyway, thinking that something invisible was going on in the site, I tried exporting and importing a large part of the site. The export seemed to work, but the import failed, initially with a complaint about an __init__() not receiving enough parameters. This was apparently from a DTMLFile class instance. Unfortunately, I hadn't backed up the Data.fs right before doing this (I was unfortunately relying on the export to work -- I know ... I should've known better). Anyway, I was hoping to try to recover this XML export file. I made a copy and tried to chop out references to the CookieUserFolder and DTMLFile objects. I figured I'd probably lose some data, but might be able to get the bulk of it to load. I did this by cutting "item" and "record" elements containing the strings "CookieUserFolder" or "DTMLFile". I did get past the __init__ error, but now am seeing a new one: cPickle.BadPickleGet I should also mention that this XML file is just over 64 megabytes in size -- I suppose I could be running out of memory or something. I don't know enough about how it's parsed to know if that's likely (but surely Zope export files are expected to be large?). I'm also inquiring with my hosting provider, who I think keeps fairly frequent backups -- I may be able to restore a not-too-old copy of my Data.fs file, but I'm hoping to get some recent data out, if at all possible. I don't really understand the structure in the XML export file. It looks really fine-grained, and I'm not sure I can easily extract data based on the original folder structure -- is there any chance of doing that (i.e. finding the most important elements out of the file and restoring just those?). Is there a way to trace the exact point in the export file where Zope failed (as it is, I get a traceback that refers to the importing code, but doesn't tell me what it was chewing on when it choked). I tried to search the Zope site for some information on this, but I'm not really sure what I should be looking for exactly. Well, anyway, any advice appreciated. I feel like an idiot, but maybe I'll learn something useful out of it. Thanks, Terry -- ------------------------------------------------------ Terry Hancock hancock(a)anansispaceworks.com Anansi Spaceworks http://www.anansispaceworks.com P.O.

Unlocking locked Folder?
by Andreas Kostyrka 25 Aug '02

25 Aug '02

Hi! I've got a small problem with one of my Zope sites: I've deleted a version, but the ZMI still shows some folders as locked by the already nonexistant version? So my question: Is there any way to unlock such a folder other then undoing the manage_deleteObject? Andreas

RE: [Zope] dtml-if fustration!

dtml-if fustration!
by Greg Conway 25 Aug '02

25 Aug '02

Hi all, I have a fustrating problem with dtml-if's!! I've tried to work round it in many ways, but there is probably an easy one I am overlooking knowing my luck... Anyway... Consider the following dtml-if statement: <dtml-if SelectSID> SelectSID = <dtml-var SelectSID> <dtml-call "REQUEST.set('SelectSID', SelectSID)"> </dtml-if> This works okay, and stores the variable SelectSID in the request for the code to pick up again on it's next pass. However, on the next pass, the variable SelectSID doesn't exist! As the variable is now REQUEST.SelectSID - and the following code doesn't work.... <dtml-if "REQUEST.SelectSID"> SelectSID = <dtml-var SelectSID> <dtml-call "REQUEST.set('SelectSID', REQUEST.SelectSID)"> </dtml-if> ...as an error is thrown up if REQUEST.SelectSID doesn't exist! Anybody got a simple answer to my dilemma?!! Many thanks for any help! Regards, Greg Conway.

FW: [Zope] dtml-if fustration! (right code!)
by Greg Conway 25 Aug '02

25 Aug '02

Okay, scrub all that... Here's the right code! :) <dtml-in "REQUEST.CustomLinkVars"> <dtml-let Counter=sequence-index> <dtml-let OuterVar=sequence-item> <dtml-if "_.getattr(REQUEST,REQUEST.CustomLinkVars[Counter])"> <dtml-if sequence-start> <dtml-if "REQUEST.Where==0"> WHERE </dtml-if> </dtml-if> <dtml-if "REQUEST.NeedSeperator==1"> AND <dtml-call "REQUEST.set('NeedSeperator',0)"></dtml-if> <dtml-var "REQUEST.CustomLinkFields[Counter]">=<dtml-var "_.int(_.getattr(REQUEST,REQUEST.CustomLinkVars[Counter]))"> <dtml-call "REQUEST.set('NeedSeperator',1)"> </dtml-if> </dtml-let> </dtml-let> </dtml-in> I'm not going to snip anything this time so I don't mess it up in any way!! REQUEST.CustomLinkVars is an array, currently containing (ie) ['SelectStudentID'] but could contain ['SelectStudentID','SelectOrgID','SelectHomeID'], etc. and could also be empty! ['']. When this array is empty, no problems - the whole section doesn't run as it's inside a <dtml-in .. > statement. that's good. The problem occurs when this array DOES contain a value, but the value of the variable it contains does not exist in the request. ie REQUEST.CustomLinkVars is an array containing ['SelectStudentID'], but SelectStudentID is not a variable in the request. I want this line... <dtml-if "_.getattr(REQUEST,REQUEST.CustomLinkVars[Counter])"> ... to test if this variable inside a variable exists inside the request, and act accordingly. BUT it doesn't - it throws up an error if the variable does not exist!! So, hopefully it makes sense THIS time!! many thanks for any help!

2.7 on dev.zope.org
by pieterb＠gewis.nl 25 Aug '02

25 Aug '02

Hello, Today, I found the page describing the 2.7 release (http://dev.zope.org/Projects/) hidden somewhere on the dev.zope.org website. It might be a good idea to link it directly from http://dev.zope.org in order for more people to find it. I think the dev.zope.org should also give a brief overview of the current direction of the Zope releases. I read the following: at http://dev.zope.org/Wikis/DevSite/Projects/SupportPython22/VisionStatement "The intent is to release Zope 2.7 in parallel with Zope 2.6. Zope 2.6 will provide new features for people who are unable to transition to Python 2.2 right away. Zope 2.7 is being driven by some specific business needs of several companies (not including Zope Corporation). For this reason, we would like to make Zope 2.7 available in August. It's possible that Zope 2.7 will be released before the release of Zope 2.6." It might be a good idea to summarize that at http://dev.zope.org/ Some other remarks about that page: - I couldn't find a way to only bug Brian about the page. Thats why I now email it to the whole community - The footer contains: "(c) 2000, Digital Creations, Inc. All rights reserved", rather outdated ;) Regards, Pieter

Howdy, Windows 2000, Zope 2.5.1 I'd like to move data.fs from \Program Files\Zope\var\data.fs to another location. I tried \Program Files\Zope\start.bat -p "c:\new\location\data.fs" , no good. TIA, Kent
