quoting:
in non-strict mode, messages don't require a blank line at the end
with a missing end-terminator. A single newline is sufficient now.
Handle trailing whitespace at the end of a boundary. Had to switch
from using string.split() to re.split()
Handle whitespace on the end of a parameter list for Content-type.
Handle whitespace on the end of a plain content-type header.
Specifically,
get_type(): Strip the content type string.
_get_params_preserve(): Strip the parameter names and values on both
sides.
_parsebody(): Lots of changes as described above, with some stylistic
changes by Barry (who hopefully didn't screw things up ;).
argument to the constructor -- defaulting to true -- which is
different than Anthony's approach of using global state.
parse(), parsestr(): Grow a `headersonly' argument which stops parsing
once the header block has been seen, i.e. it does /not/ parse or even
read the body of the message. This is used for parsing message/rfc822
type messages.
We need test cases for the non-strict parsing. Anthony will supply
these.
_parsebody(): We can get rid of the isdigest end-of-line kludges,
although we still need to know if we're parsing a multipart/digest so
we can set the default type accordingly.
email package's Parser to handle the three common line endings.
Certain protocols such as IMAP define CRLF line endings and it doesn't
make sense for the client app to have to normalize the line endings
before handing it message off to the Parser.
_parsebody(): Be more flexible in the matching of line endings for
finding the MIME separators. Accept any of \r, \n and \r\n. Note
that we do /not/ change the line endings in the payloads, we just
accept any of those three around MIME boundaries.
non-us-ascii character sets in headers and bodies. Some API changes
(with DeprecationWarnings for the old APIs). Better RFC-compliant
implementations of base64 and quoted-printable.
Updated test cases. Documentation updates to follow (after I finish
writing them ;).
headers. It does not parse the body of the message, instead simply
assigning it as a string to the container's payload. This can be much
faster when you're only interested in a message's header.
Also, add a clause to the big-if to handle message/delivery-status
content types. These create a message with subparts that are
Message instances, which best represent the header blocks of this
content type.
<http://sf.net/projects/mimelib>. There /are/ API differences between
mimelib and email, but most of the implementations are shared (except
where cool Py2.2 stuff like generators are used).
