ZODB.blob.rename_or_copy_blob may silently overwrite existing blob files since it uses os.rename without checking for the target file first. This may affect committed data although we remove write permissions after the commit.
This seems questionable to us, so we wonder whether it is actually desired behaviour or a bug. We think raising an error would be appropriate. -- Thomas _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
