After updating Twisted to 12.3.0 I started getting errors like the following one
2013-01-17 14:38:23+0100 [-] File
"/usr/lib64/python2.7/site-packages/twisted/names/common.py", line 93, in

2013-01-17 14:38:23+0100 [-] TypeError: u'example.com' is not a byte string
Taking a look at documentation I found this document
http://twistedmatrix.com/documents/current/core/howto/python3.html
which states
"twisted.names.dns deals with strings with a wide range of meanings,
often several for each DNS record type. Most of these strings have
remained as byte strings, which will probably require application
updates (for the reason given in the FilePath section above). Some
strings have changed to text strings, though. Any string representing a
human readable address (for example, Record_A's address parameter) is
now a text string. Additionally, time-to-live (ttl) values given as
strings must now be given as text strings."
which seems to describe the problem I'm experiencing.
But let me say that I'm currently using Python 2.7.3 and I was surprised in
realizing
that a simple update from a minor 12.x release was enough to disrupt my
application.
Don't you think that a kind of compatibility mechanism (maybe with a warning
message)
would have been a more gentle way of doing this transition especially for those
who
are still using Python 2?
Thanks and regards,
