Well, I know _I_ think Session support is important (hint: I wouldn't have spent the effort on SQLSession otherwise). If the decision was made to take the CST package and change the interface before making it part of the preinstalled set of Products, I'd _strongly_ urge that the documentation for it be updated.

ghosts of removed products haunting ZSQL Methods?
by John Ziniti 09 Jan '02

09 Jan '02

I used to have the Product TrackerBase installed and have removed it. Now, however, attempts to access the "Advanced" tab of ZSQL Methods is broken because a chain of events attempt to get info about a the non-existent Product: lib/python/Shared/DC/ZRDB/dtml/advanced.dtml calls manage_product_zclass_info ../ZRDB/DA.py.manage_product_zclass_info (line 546) calls self.aq_acquire('_getProductRegistryData')('zclasses') One of these items is the dict: "{'id': 'Tracker', 'meta_type': 'Tracker', 'product': 'Tracker', 'meta_class': <ZClass instance at d55af0>} Then, line 548 calls "if hasattr(z._zclass_,'_p_deactivate')". The attempt to access z._zclass_ fails because this product doesn't exist. 1) the call to z._zclass_ doesn't actuallt do anything except: ## Eek, persistent 2) Is this schizophrenic state my fault? 3) How to rectify the problem (Make *all* of Zope know that TrackerBase is gone)?

Session Tracking in 2.5
by seb bacon 08 Jan '02

08 Jan '02

I thought it was time to catch up on the CST stuff which has made it into the core, only to find that it's only *based on* Chris' CST stuff. And I can't find a fishbowl project anywhere describing the rationale, apis, whatever... Is there a fishbowl for this? Or was session tracking implemented as a guerilla project? seb

_getProductRegistryData('zclasses') returns non-existent Products -- permission to muck around?
by John Ziniti 08 Jan '02

08 Jan '02

My ProductRegistry has references to products which no longer exist in my Zope installation. This causes a variety of problems in lots of different places when other products try to get more information about all the products in the ProductRegistry (obviously). 1) How does this occur? 2) Is it OK to put my boots on, get in there and manually delete entries which refer to non-existent Products? TIA Ziniti

Zope 2.5.0 Sessions & Testing
by Chris Withers 08 Jan '02

08 Jan '02

Hi, Trying to test a URL in a unittest.py test using code as follows: apply(Site.restrictedTraverse('/folder/cmfsite/skinmethod'),params) Now, skinmethod uses the new Zope 2.5.0 sessioning: session=context.REQUEST.SESSION session.set('key','value') but the BeforeTraversal hook doesn't seem to kick in when restrictedTraverse is used :-( We always get an AttributeError on SESSION. How should we fix this and go about testing this method properly? cheers, Chris

asyncore.py & Broken-Pipe error
by Dirk Datzert 08 Jan '02

08 Jan '02

Hi, I knew that sometimes ZServer stopps working with the error OS-error Broken-Pipe in the log-file. And I knew that this is fixed in Zope 2.5b with a change of asyncore.py I need a working asyncore.py for my 2.4.3 Zope. Can anybody sent me a working version ?

PDF-specific Bug in the ZServer implementation??? Or just strange behavoiur of IE?
by Joachim Werner 07 Jan '02

07 Jan '02

Hi! This is my first post in the new year, so best wishes for 2002 from Germany! And on we go with my problem: I have a ZClass-based Class derived from File. It holds PDF documents. SOME (not all) of them do not auto-open in Acrobat Reader as they are supposed to if MS IE 5.x is used. Opera etc. seem to work. The files themselves are o.k., and opening in Acrobat Reader AFTER downloading (via right mouseclick/save as) works fine, too. If the same document that doesn't auto-open when downloaded fom the Zope server is downloaded from plain Apache, it works ... The configuration is Zope 2.4.1 (binary release, python 2.1, linux2-x86), python 2.1.0, linux2 on a SuSE Linux with Apache as Proxy server (via proxy_pass). I checked the HTTP header with WGET, and they are identical for working and non-working PDF docs. The mime type is set to application/pdf ... Any hints on that? Joachim

Hi! Just to answer my own question and complete the mail archive: If you have problems with downloads that make use of the HTTP range functionality (e.g. with the latest Acrobat Reader in MS IE), Zope 2.5 fixes the problem (for me).
