[yep, copied on this message] For perpetuity: In a private discussion Jim explained that the blob .open() method returns things intended to be file-like, but the method itself isn't intended to mimic Python's "open" function, and as-such doesn't support the additional mode variations. This distinction is similar to why __init__ methods aren't described in (zope.interface) interfaces; how you construct an object isn't prescribed by the interface exposed by the object itself. -- Benji York Senior Software Engineer Zope Corporation _______________________________________________ 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
