Message335424
When converting an email.message.Message with the policy set to email.policy.EmailPolicy with all default settings, I eventually end up with this exception:
File "/usr/lib/python3.7/email/_header_value_parser.py", line 2727, in _fold_as_ew
first_part = to_encode[:text_space]
TypeError: slice indices must be integers or None or have an __index__ method
Which is caused because text_space is a float of value +inf. This is set on line 2594 of the same file: maxlen = policy.max_line_length or float("+inf")
For some reason policy.max_line_length is set to zero, even though the default should be 78 after a glance into the source.
So there's maybe even two issues:
1.) The fallback for maxlen shouldn't be float("+inf"), as that is not an integer and thus can't be sliced by. I think a big integer would suffice instead, for example 100000000
2.) policy.max_line_length seems to lose it's value in the default settings somewhere along the way if it isn't explicitly set.
Current workaround:
Set max_line_length of the policy to a value (78 is default) |
