email package and line ending

[Manlio Perillo]

Regards.

The problem is this code:
[color=blue][color=green][color=darkred]
>>> import email.Message
>>> msg = email.Message.M essage()
>>> msg["subject"] = "email bug"
>>> msg["from"] = "Manlio Perillo"
>>> print repr(msg.as_str ing())[/color][/color][/color]
'subject: email bug\nfrom: Manlio Perillo\n\n'


Why line ending is '\n' and not '\r\n' ?
RFC 2822 says that the delimiter must(?) be '\r\n'.

The same problem is presente in email.Generator and email.Header (for
multiline headers).


P.S.
email.Header has a bug:

this code causes an infinite recursion:
[color=blue][color=green][color=darkred]
>>> from email.Header import Header
>>> h = Header('multili ne header', 'iso-8859-1', maxlinelen=4)
>>> e.encode()[/color][/color][/color]

Because all you have there is a string. It doesn't have anything to do
with RFC 2822. \n is probably the safest cross-platform way to represent a
newline in a Python string.

Note that smtplib, which DOES have to worry abouot RFC 2822 compliance,
will replace all standalone \r and \n characters with \r\n.

I'm not sure I would call that a bug. I'd call that a usage error; you've
asked it to accomplish something that cannot be done. However, it is true
that _split has enough information to diagnose this.
