Proposed new URL rules for explicit namespace control in Zope
by Jim Fulton 10 Nov '01

10 Nov '01

We are proposing to introduce some new syntax in Zope URLs to provide explicit namespace control, including: - Avoiding name conflicts between folder content ids and folder presentation names, and - Suppoting explicit rather than implicit acquisition. The issues are, IMO, surprisingly subtle and complicated. The issues are described at some length at: http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/ExplicitNa… If you would like to wade in, comments (especially Wiki comments :) are welcome.

pdf - "Files" not viewable
by Tim McLaughlin 09 Nov '01

09 Nov '01

This used to work, and I'm vexed as to why it doesn't now. When PDFs are uploaded as file objects and then viewed, on IE 5.0+ with Acrobat Reader, they appear as blank when Acrobat Reader pops up to read them. I get no errors on the stupid log, and generally haven't any idea what the deal is since this used to work. Did something change in 2.4 that could have caused File objects to function badly? Thanks, Tim -- Tim McLaughlin iterationZERO - www.iterationzero.com 703.481.2233

Debugging help wanted for really weird ZClass problem
by Matt Behrens 09 Nov '01

09 Nov '01

I need some debugging help with a problem I've had with 2.4 and ZClasses. I have been completely unsuccessful in tracking this one down so I can reproduce it and file a proper bug report on it. Specifically, while developing ZClasses (occasionally deleting and recreating them, i.e. to change base classes), I will often get to a point where I get a traceback ending in NameError: global name 'ClassName' is not defined I'm using the default constructor DTML method in this case, although a python script yields the same error. I thought I had this trapped in the wild, as I backed up Data.fs with the broken behavior, then exported the ZClass products this particular one depended on, made a new Data.fs, and reimported them. They worked. So then I restored the old Data.fs and it was suddenly working (no amount of packing, restarting, or cleanGlobals-ing could get me this far before, but somehow backing up and restoring Data.fs did...?) I'm really stumped here. Anyone have a clue or three? I'm willing to do some debug legwork if I can catch it again... -- Matt Behrens <matt.behrens(a)kohler.com> System Analyst, Baker Furniture

ZMailIn patch (index 'date' as DateTime object)
by Jean Jordaan 09 Nov '01

09 Nov '01

Hi Andy & all There I was, trying to select last week's mail messages from the ZMailInCatalog, when I realized that the 'date' index was a simple string. Here's a patch, adding a property 'datetime', which can be used as an index of type DateTime. Anything I'm missing here? In particular, I'm not sure I understand what 'sortableDate' is meant for. It's a string like this:: str('%04d%02d%02d%02d%02d%02d' % (dateTuple[0],dateTuple[1], dateTuple[2],dateTuple[3],dateTuple[4],dateTuple[5])) But it's still a string, and can't be used in comparisons with DateTimes. Why not just use 'datetime', also sortable?

RE: [Zope-dev] Deleting objects in BTreeFolder

Oops... this isn't a problem; I accidentally passed _delObject() an object reference instead of its id... Doh. My bad.

How To Upgrade 2.3 to 2.4??
by Chris Bruce 08 Nov '01

08 Nov '01

Hi, I was wondering how to upgrade Zope Version 2.3 to 2.4? I looked for documentation, but nothing mentions if my data.fs will stay intact after the install. Also, I would like to test my existing site under 2.4 before upgrading. Can I just copy the products and the data.fs to the fresh Zope 2.4 install or is there a specific upgrade path? Any help, is mucho appreciated. Thanks, Chris __________________________________________________ Do You Yahoo!? Find a job, post your resume. http://careers.yahoo.com
