| Identifier | resource ID | http://old.zope.org/Collectors/Ape/10 |
| Title | resource name | Read conflict errors. |
| Description | resource summary | How to reproduce: 1) in /fs create folder a 2) in /fs create script: updateA with content: context.a.manage_editProperties({'title' : 'ABC'}) 3) in /fs/a create four folders: '1', '2', '3', '4' 4) restart zope 5) right after restarting zope execute: /fs/updateA - it will give you conflict error: ConflictError: ('/fs/a/1',) already exists This happened because when 'a' is loaded it creates 4 'ghosted' objects '1', '2', '3', '4'. Ape treated ghosted objects as new objects because setstate function was not yet called and getState function (in zodb3.connection.py ) for those objects will return HASH0. I have created patch for connection.py that works for me but not 100% sure that I didn't brake anything else: ---------------------------------------- diff -w -b -r1.1 connection.py 256a257 > ghostyObject = 0 262a264 > ghostyObject = 1 267a270 > if ghostyObject : continue |
