Hi, it seems (in fact I'm sure) there's a bug in changeOwner's behavior: I suspect changeOwner of changing ownership on the folder's content when you change ownership on the folder itself, e.g.: Folder-A |--Folder-B |--Object-C |--Folder-D |--Object-E if I change ownership on A but not its subobjects, then it seems that ownership is changed on A,B, C and D, while E retains its original ownership. is it normal ? To me it's not. it seems like if you try to change ownership recursively from an object (Folderish) on something you already own, changeOwner returns successfully immediately even if you're not the owner of the complete subtree. AccessControl/Owner.py says: --- CUT --- if old==new: return --- CUT --- which seems to confirm my point. any comment ?
