The current module is broken in py3k. I suppose it is still usable for
things like fetching group descriptions, but you can't e.g. read
Also, http://bugs.python.org/issue9360 mentions that API changes were
discussed by Brett and the OP at EuroPython (I wasn't there):
“Change API methods to return strings instead of bytes. This breaks API
compatibility, but given that the parameters need to be passed as
strings and many of the returned values would need to be passed to
other API methods, I consider the current API to be broken. I've
discussed this with Brett at the EuroPython sprint, and he agrees.”
My changes build on the patch proposed on this issue and add further
Yes, the new API could be checked in as "nntplib2" instead. I am a
bit uneasy with that, though, since 1) the original nntplib would still
be broken 2) the changes I have in mind don't seem enough to warrant
such a grandiloquent naming :-)
