Sorry folks, I figured it out. Turns out I was sending a Cache Control header elsewhere in the code. That was preventing IE from saving the file in it's temp internet files folder, and that's why "open" didn't open squat - the file never got cached... In hindsight it makes perfect sense...

importing files into Zope?
by Manuela 12 Jan '04

12 Jan '04

Hi there, I have a problem with importing files into Zope and maybe you can help? I have installed Zope on an Apache server on my Windows machine at home. Everything is working fine, but when I try to import an .zexp file (which I exported from Zope at work) it does show the folder with the correct name but when I click on that folder, I get the following error message: ------------------- Zope Error Zope has encountered an error while publishing this resource. Error Type: AttributeError Error Value: __getitem__ Troubleshooting Suggestions The URL may be incorrect. The parameters passed to this resource may be incorrect. A resource that this resource relies on may be encountering an error. For more detailed information about the error, please refer to the HTML source for this page. If the error persists please contact the site maintainer. Thank you for your patience. --------------------- There are some subfolders in that folder. I can click on the "+" next to the folder and it will show the tree with the subfolders but I can't open any of the folders. I guess that the Zope version at work is older than the one I have on my home computer. Could that be a problem? Thanks for your help.

RE: Zope Digest, Vol 6, Issue 15

Hi Jim, Perhaps the solution to your problem: Delete the "Temporary Internet Files" in Internet Explorer and try again. I had similar problems with viewing the source of webpages. Deleting the cache was a solution on the microsoft website and it worked for my problem. It seems an IE bug that exposes itself when the cache limit is (almost) reached.

FieldedTextIndex weighting implemented
by Casey Duncan 12 Jan '04

12 Jan '04

I have an initial implementation of the per-field weighting checked into cvs. I haven't released 0.2 yet, but I expect to sometime in the next week or so. The new feature is unit-tested and documented in the README, so feel free to check it out in the mean time. You can download it directly from CVS at: http://cvs.zope.org/Products/FieldedTextIndex/ There is a link to generate a tarball at the bottom, or you can check in out using anonymous cvs if you want to track changes. Let me know what you think. -Casey

The first thing I would try to do is look at the security tab in the root of your Plone instance. Take all of the permissions normally assigned to 'Member' (and perhaps to 'Owner' if that doesn't work) and assign them to anonymous. If that works, try removing the permissions that you feel are overkill one by one (my guess here is that anonymous needs 'List Folder Contents', but it really could be almost anything). If that doesn't work try installing the VerboseSecurity product, and erasing the CookieCrumbler 'cookie_authentication' instance's 'Auto-login page ID' field so that you can see the traceback and which permissions are needed. I hope that helps. Alec Mitchell

Zope 2.6.3 and min (...)
by Gilles Lenfant 11 Jan '04

11 Jan '04

I see that "min" and others have been removed from "secure" python (TTW scripts, dtml...). Is this a bug or a VERY BAD idea ? x = _.min([1,2,3,4]) return x Runs perfectly with Zope 2.6.2. but raises this with Zope 2.6.3... Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 261, in __call__ Module Shared.DC.Scripts.Bindings, line 292, in _bindAndExec Module Products.PythonScripts.PythonScript, line 311, in _exec Module test, line 1, in test - <PythonScript at /test> - Line 1 AttributeError: min Now I got to make my own "min", "max"... functions or externals to override this or wait for the bugfix :-( Or stay with Zope 2.6.2 -- Gilles

Undo machinery and OOBtrees
by Alec Mitchell 11 Jan '04

11 Jan '04

Hello, I hav a python product that I'm working on which contains a content class which uses OOBtrees and OOSets internally for storing structured data. The problem is that changes to this object which involve those structures do not seem to be undoable (i.e. no transaction shows up in the manage_undo or manage_change_history_page of the instance or its parent). I've tried explicity using get_transaction() to commit and annotate the transaction, and the note seems to end up in the Data.fs, but the transaction still does not appear. Are those datatypes not subject to transactions in the usual manner? Is there a way around this? Should I just use dictionaries and _p_changed if I want to track revisions? Thanks in advance for any enlightenment on these issues. Alec Mitchell
