New submission from R. David Murray <rdmur...@bitdance.com>:
>>> socket.create_connection(('a..com', 25))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/rdmurray/python/py3k/Lib/socket.py", line 300, in
create_connection
for res in getaddrinfo(host, port, 0, SOCK_STREAM):
File "/home/rdmurray/python/py3k/Lib/encodings/idna.py", line 167, in encode
result.extend(ToASCII(label))
File "/home/rdmurray/python/py3k/Lib/encodings/idna.py", line 73, in ToASCII
raise UnicodeError("label empty or too long")
UnicodeError: label empty or too long
I have two problems with this: why is it a UnicodeError? (That confused me
into going down a blind alley before finding my typo in the original context
where I encountered this). The other problem is the term 'label'. I realize
this is technically correct and precise, but I doubt most users will recognize
it (I didn't remember what it meant until I looked it up). Could we perhaps
change it to 'domain name subpart'?
Note that in 2.x this gives 'name or service not known' unless the input string
is unicode, in which case it gives the error above. So in 2.x the UnicodeError
was at least not totally dissociated from the cause of the error, but still
strikes me as sub-optimal. I would expect a ValueError.
