Can't pickle function objects error
by Gitte Wange 19 Aug '04

19 Aug '04

Hello, I have tried and google for an answer to this but without any luck. I have added an attribute to a class which saves an integer and the above error is raised: Traceback (innermost last): * Module ZPublisher.Publish, line 104, in publish * Module Zope.App.startup, line 221, in commit * Module ZODB.Transaction, line 233, in commit * Module ZODB.Transaction, line 348, in _commit_objects * Module ZODB.Connection, line 417, in commit __traceback_info__: (('Products.MyMediaManager.MediaEvent', 'MediaEvent'), '\x00\x00\x00\x00\x00\x00\x1a\x92', '') * Module copy_reg, line 69, in _reduce_ex TypeError: can't pickle function objects (It didn't happen before I added this attribute so I'm quite sure that is the reason for the error). My code looks like this: poster_rotation = req.get('poster_rotation', None) if poster_rotation is not None: self._poster_rotation = int(poster_rotation) I'm running Zope-2.7, Python-2.3.3 and Plone-2.0.3 Any hints? Greetings, Gitte Wange

cookiecrumbler and webdav
by John Hunter 19 Aug '04

19 Aug '04

I have some File instances on my zope server and am using cookie crumbler for authetication. I have the various view, access and webdav permissions set so the user has permission to access the document. When using internet explorer, the http basic authorization dialog box pops up (the user then can reenter their username and passwd and all is well). I would like to avoid forcing the user to reauthenticate. >From my googling, it appears there is a problem using cookie based authentication and webdav. The cookiecrumbler readme states If CookieCrumbler gets in the way of WebDAV interactions, use a WebDAV source port (see the Zope documentation.) Could someone elucidate? Does this mean I should munge the link to the document do it is accessed as, for example http://mysite.com:1980/somefile.doc where 1980 is my <webdav-source-server> address? Actually, I don't want the documents to be editable (they are read only). Ideally, the documents would be accessed via normal http. Is there a way to make this happen on the server side w/o having to make all the clients change their browser settings. I saw some reference top WEBDAV_SOURCE_PORT_CLIENTS in the zope book which looked a little promising along these lines. Is there any guidance for how this variable should be used with internet explorer? Thanks, John Hunter

problem downloading PDF:File does not begin with '%PDF-
by robert rottermann 19 Aug '04

19 Aug '04

Hi there, for some time (10 days) we have problems downloading PDF-Files from a zope site. It used to work before. The only thing that was done, was updating Linux with security updates. Now we get on windows clients:File does not begin with '%PDF-' (both with IE6.x, Firebird, Mozilla). On a Linux client things work fine. When I change the content-type in the ZMI from application/pdf to application/x-pdf The file is downloaded and presented in the acrobat reader without glitch. What we use is: Zope 2.7 Python 2.3.3 Apache 2 Suse Linux 9.1 (Kernal 2.6) Can somebody indicate me towards an solution less radical than changing all content-types ? Thanks Robert

PloneLocalFS problem
by Kamil Kaczorowski 18 Aug '04

18 Aug '04

Hi, similar question was posted some time ago at the list but no answer was given. I want to use PloneLocalFS in my application. There's no input or something else to hook my local fs directory to the product. Is it some kind of bug?. I've tried PloneLocalFS-0.0.7 on Zope2.7.0. Thanks for any answer or links to documentation.
