#1050268: make parseaddr 'quote' the contents of quoted strings in addresses.
Also made the doc string for email._parseaddr's 'quote' function more
accurate; I'd love to make the function match the old docstring instead,
but other code uses it according the existing semantics.

#1194222: make parsedate always return RFC2822 four character years.
Two character years are now converted to four character years using
the Posix standard rule (<68 == 2000, >=68==1900). This makes the
parsed date RFC2822 compliant even if the input is not.

#3196: if needed pad a short base64 encoded word before trying to decode.
The RFCs encourage following Postel's law: be liberal in what you accept.
So if someone forgot to pad the base64 encoded word payload to an
even four bytes, we add the padding before handing it to base64mime.decode.
Previously, missing padding resulted in a HeaderParseError.

#1555570: correctly handle a \r\n that is split by the read buffer.
Patch and test by Tony Nelson.
........
Previously, unexpected results occurred when email was passed, for example,
'utf8' as a charset name, since email would accept it but would *not* use
the 'utf-8' codec for it, even though Python itself recognises that as
an alias for utf-8. Now Charset checks with codecs for aliases as well
as its own internal table. Issue 8898 has been opened to change this
further in py3k so that all aliasing is routed through the codecs module.
If a body part ended with \r\n, feedparser, using '$' to terminate its
search for the newline, would match on the \r\n, and think that it needed
to strip two characters in order to account for the line end before the
boundary. That made it chop one too many characters off the end of
the body part. Using \Z makes the match correct.
Patch and test by Tony Nelson.
Fixes (mysterious, to the end user) UnicodeErrors when using utf-8 as
the charset and unicode as the _text argument. Also makes the way in
which unicode gets encoded to quoted printable for other charsets more
sane (it only worked by accident previously). The _payload now is encoded
to the charset.output_charset if it is unicode.
Yukihiro Nakadaira noticed a typo in encode_7or8bit that was trying
to special case iso-2022 codecs. It turns out that the code in
question is never used, because whereas it was designed to trigger
if the payload encoding was eight bit but its output encoding was
7 bit, in practice the payload is always converted to the 7bit
encoding before encode_7or8bit is called. Patch by Shawat Anand.
base64 transfer-encoded payload *after* decoding it; it no longer does.
email had a special method in utils, _bdecode, specifically to do this,
so it must have served a purpose at some point, yet it is clearly wrong
per RFC. Fixed with Barry's approval, but no backport. Email package
minor version number is bumped, now version 4.0.1.
Patch by Joaquin Cuenca Abela.
message/rfc822 it turns it into an object whose body consists of
a list containing a single Message object. HeaderParser, on the
other hand, just copies the body as a string. Generator.flatten
has a special handler for the message mime type that expected the
body to be the one item list. This fails if the message was parsed
by HeaderParser. So we now check to see if the body is a string
first, and if so just we just emit it.
headers in multipart/signed MIME parts, which fixes one of the sources of
invalid modifications to such parts by Generator. Patch and tests by
Martin von Gagern.
though with some changes by me. This patch should not be back ported or
forward ported. It's a bit too risky for 2.6 and 3.x does things fairly
differently.
[ 1752723 ] email.message_from_string: initial line gets discarded
I added a test to assert that when the first line of text passed to
message_from_string() contains a leading space, the message ends up with the
appropriate FirstHeaderLineIsContinuationDefect on its defects list.
The bug is invalid.
2047-like headers where there is no whitespace between encoded words. This
fix changes the matching regexp to include a trailing lookahead assertion that
the closing ?= must be followed by whitespace, newline, or end-of-string.
This also changes the regexp to add the MULTILINE flag.
it into email 4.0. Specifically, in Message.get_content_charset(), handle RFC
2231 headers that contain an encoding not known to Python, or a character in
the data that isn't in the charset encoding. Also forward port the
appropriate unit tests.
points out there are really two types of continued headers defined in this
RFC (i.e. "encoded" parameters with the form "name*0*=" and unencoded
parameters with the form "name*0="), but we were were handling them both the
same way and that isn't correct.
This patch should be much more RFC compliant in that only encoded params are
%-decoded and the charset/language information is only extract if there are
any encoded params in the segments. If there are no encoded params then the
RFC says that there will be no charset/language parts.
Note however that this will change the return value for Message.get_param() in
some cases. For example, whereas before if you had all unencoded param
continuations you would have still gotten a 3-tuple back from this method
(with charset and language == None), you will now get just a string. I don't
believe this is a backward incompatible change though because the
documentation for this method already indicates that either return value is
possible and that you must do an isinstance(val, tuple) check to discriminate
between the two. (Yeah that API kind of sucks but we can't change /that/
without breaking code.)
Test cases, some documentation updates, and a NEWS item accompany this patch.
Specifically, instead of raising a ValueError when there is a single tick in
the parameter, simply return that the entire string unquoted, with None for
both the charset and the language. Also, if there are more than 2 ticks in
the parameter, interpret the first three parts as the standard RFC 2231 parts,
then the rest of the parts as the encoded string.
Test cases added.
Original fewer-than-3-parts fix by Tokio Kikuchi.
Resolves SF bug # 1218081. I will back port the fix and tests to Python 2.4
(email 3.0) and Python 2.3 (email 2.5).
Also, bump the version number to email 4.0.1, removing the 'alpha' moniker.
Patch #1464708 from William McVey: fixed handling of nested comments in mail
addresses. E.g.
"Foo ((Foo Bar)) <foo@example.com>"
Fixes for both rfc822.py and email package. This patch needs to be back
ported to Python 2.3 for email 2.5.
SF bug #1403349 solution for email 3.0; some MUAs use the 'file' parameter
name in the Content-Distribution header, so Message.get_filename() should fall
back to using that. Will port to the Python 2.5 trunk.
Also, bump the email package version to 3.0.1 for eventual release. Of
course, add a test case too.
