Well, I figured out a kludge from the "How to backup Zope data base?" thread and from the rc shutdown script. Turns out I needed to remove the Data.fs.*, pcgi.soc, and *.pid files -- leaving ONLY Data.fs and a few others, like the FSSession directory. That got both 2.2.5 and 2.3b1 to start up with my data. Only problem is that all instances of the ZClass I had created in my product (which I named ArticleProduct, btw) are broken in 2.3b1. The product itself appears in the Product Management menu, but even instances of ZClasses within the product are broken. Re-importing ArticleProduct.zexp does no good... I still get that "append" AttributeError (see traceback below). Is this a bug w/ 2.3b1 or am I missing something? Any help? ajl
I'm trying to upgrade to 2.3.0b1 from 2.2.5b1... I installed the new version (according to the ZopeInstall HowTo, just to be safe), which started fine. I then shutdown Zope (2.3.0b1), moved the default var/Data.fs* files to a backup directory, then copied my old Data.fs* files over. When I tried to re-start 2.3.0b1, nothing happened. No debug message either. So I put the default Data.fs* files back in and restarted successfully.
Fine, I thought, the database files aren't all that necessary. All the work I'd done on the previous version had been exported to a .zexp product export file, which were all subclassed from your run-of-the-mill ZClasses (image, file, folder, object manager, ZCatalog aware) and used DTML for all methods. No PythonMethods, no FSSessions, etc. So I put the .zexp file into the "import" folder and tried to import the product from within Zope. I got this error:
Error Type: AttributeError Error Value: append
Traceback (innermost last): File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/2-3/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/2-3/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_importObject) File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_importObject) File /usr/local/zope/2-3/lib/python/OFS/ObjectManager.py, line 542, in manage_importObject (Object: Traversable) File /usr/local/zope/2-3/lib/python/ZODB/ExportImport.py, line 208, in importFile AttributeError: (see above)
Here's my questions: 1. Why are my old data files screwing up Zope 2.3.0b1? 2. Why can't I import my product?
Note: I also tried this with 2.2.5b1 --> 2.2.5, same errors.
Any insights? Thanks, ajl
