Amaury Forgeot d'Arc <[EMAIL PROTECTED]> added the comment:
Python 2 is very platform-dependent: fdopen simply call the C function
fdopen() and returns a FILE*.
Since the sample code is a mistake (read on a file open in write mode),
how and when the error shows up really depends on the platform's
implementation of the FILE* object.
On the other hand Python 3 re-implemented all this, no FILE is used. The
io.UnsupportedOperation("BufferedWriter.read() not supported") is much
better IMO. And note that io.UnsupportedOperation is a IOError as well.
However the AttributeError is inconsistent. The attached patch turns it
into a UnsupportedOperation as above.
