Oh so close... Migrated from Zope 2.7.2 to 2.8.1 Updated all the Catalog instances according to the instructions. Fixed a few outdated products. Then just for kicks, I tried to update the Python scripts by visiting the /manage_addProduct/PythonScripts/recompile url. After about a minute, it threw up an error page. This is what shows up in the log... 2005-08-21T01:56:45 ERROR txn.170046464 Error in abort() on manager <Connection at 0956724c> Traceback (most recent call last): File "/Zope-2.8/lib/python/transaction/_transaction.py", line 456, in _cleanup File "/Zope-2.8/lib/python/ZODB/Connection.py", line 348, in abort File "/Zope-2.8/lib/python/ZODB/Connection.py", line 360, in _abort AssertionError ------ 2005-08-21T01:56:45 ERROR Zope.SiteErrorLog http://someurl.com/manage_addProduct/PythonScripts/recompile Traceback (most recent call last): File "/Zope-2.8/lib/python/ZPublisher/Publish.py", line 119, in publish File "/Zope-2.8/lib/python/Zope2/App/startup.py", line 215, in commit File "/Zope-2.8/lib/python/transaction/_manager.py", line 84, in commit File "/Zope-2.8/lib/python/transaction/_transaction.py", line 381, in commit File "/Zope-2.8/lib/python/transaction/_transaction.py", line 379, in commit File "/Zope-2.8/lib/python/transaction/_transaction.py", line 424, in _commitResources File "/Zope-2.8/lib/python/ZODB/Connection.py", line 462, in commit File "/Zope-2.8/lib/python/ZODB/Connection.py", line 483, in _commit AssertionError Nothing appears to be broken yet but I'm wondering whether I should roll back to my backup. Anyone have any ideas about this error? I'm tempted to just pretend that I didn't see it.
