Chris, please help me understand how this makes a difference in ZODB. I currently store a persistent list in the ZODB as follows: root[db_name] = some list
What class do you use for the list?
I suspect root's class isn't too clever, but I can't remember...
Are you suggesting that I store it in some other, nested dictionary off of root, such as:
root[db_name][listname] = some list
Yes, in particular:
from BTrees.OOBTree import OOBTree root[db_name]=OOBTree() root[db_name]['something']=your_list
the btrees implementations are specially designed to minimise the kind of conflict errors you've been experiencing. They work just like python dictionaries...
cheers,
Chris
