Re: [Zope] zope operations atomic?

I don't want to be dense but it sounds like for each thread a deep copy of the items it accesses- Folder for example- is made. When session ends or something triggers a commit a check is made for conflicts.

A commit is triggered by the finalization of every HTTP request.

This sounds a bit scarry because if you have a script changing resources like a Folders it is almost certain then that there will be a conflict. At this point a retry still find conflicts. I would rather have heard the Folder was a critical section or methods like manage_changeProperties were atomic. IMHOP it should be so.

Though it sounds like you have a valid concern, I can't seem to pick it out of that series of words. ;-) What is it that you're worried about? - C
