Hello,
I thought BTrees have conflict resolution code.
We have here a weird conflict here, the BTree in question is a
SessionDataContainer. The conflict seems to appear when one transaction
removes and the other adds an entry.
(snip)
/ZODB/Connection.py", line 566, in commit
self._commit(transaction)
File
"/home/zope/eggs/ZODB3-3.9.7-py2.6-linux-x86_64.egg/ZODB/Connection.py",
line 614, in _commit
self._store_objects(ObjectWriter(obj), transaction)
File
"/home/zope/eggs/ZODB3-3.9.7-py2.6-linux-x86_64.egg/ZODB/Connection.py",
line 666, in _store_objects
s = self._storage.store(oid, serial, p, '', transaction)
File
"/home/zope/eggs/ZODB3-3.9.7-py2.6-linux-x86_64.egg/ZODB/FileStorage/FileStorage.py",
line 512, in store
data=data)
ConflictError: database conflict error (oid 0x18, class
