New submission from Ezio Melotti <ezio.melo...@gmail.com>:
def _decode_header_to_utf8(self, hdr):
l = []
for part, encoding in decode_header(hdr):
if encoding:
part = part.decode(encoding)
l.append(part)
return ''.join([s.encode('utf-8') for s in l])
If the encoding is specified, l becomes a list of unicode strings that can be
encoded in the listcomp, but if the encoding is not specified, l becomes a list
of byte strings that can't be encoded if they contain non-ascii characters.
The latter causes lot of decoding errors that gets reported to the admins due
to all the spam messages (apparently with no encoding specified) that get sent
to b.p.o.
I'm going to fix this by attempting the decoding of the part using utf-8 and
falling back to iso-8859-1 in case of error. This will ensure that l is a list
of unicode strings that can be encoded. This will also stop the decoding
errors in the listcomp, and let the spam messages through, hopefully to be
blocked shortly after when Roundup figures out the user is not registered.
