Message 319145 - Python tracker (original) (raw)
I was making suggestions, not demanding anything. Except for the quirk with del, Gary’s changes (revision fb28362) look okay to add on their own as a bug fix.
I wouldn’t claim that IOBase is “fully implemented” however, until the return values for “seek” and “truncate” are fixed.
The underlying problem is the original SpooledTemporaryFile imitated Python 2’s file class/type, and wasn’t completely adapted for Python 3’s file classes.
