Recently, without changes to codes/libs, I started getting python error_proto: line too long error when reading email (poplib.retr) from hotmail inbox. I am using Python version 2.7.8. I understand that a long line may be caused this error. But is there a way to go around this or a certain version I need to put in place. Thank you for any advice/direction anyone can give.
Here is a traceback error:
"/opt/rh/python27/root/usr/lib64/python2.7/poplib.py", line 232, in retr\n return self._longcmd(\'RETR %s\' % which)\n',
' File "/opt/rh/python27/root/usr/lib64/python2.7/poplib.py", line 167, in _longcmd\n return self._getlongresp()\n',
' File "/opt/rh/python27/root/usr/lib64/python2.7/poplib.py", line 152, in _getlongresp\n line, o = self._getline()\n',
' File "/opt/rh/python27/root/usr/lib64/python2.7/poplib.py", line 377, in _getline\n raise error_proto(\'line too long\')\n',
'error_proto: line too long\n'
Are you sure you've not updated poplib? Have a look at the most recent diff, committed last night:
# Added:
...
# maximal line length when calling readline(). This is to prevent
# reading arbitrary length lines. RFC 1939 limits POP3 line length to
# 512 characters, including CRLF. We have selected 2048 just to be on
# the safe side.
_MAXLINE = 2048
...
# in_getline()...
if len(self.buffer) > _MAXLINE:
raise error_proto('line too long')
...it looks suspiciously similar to your problem.
So if you roll back to the previous version, it will probably be OK.
