Barry Warsaw 81a06d4260 In response to this SF bug:
[ 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.

Barry Warsaw dcd24ae501 SF bug #1582282; decode_header() incorrectly splits not-conformant RFC
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.

Barry Warsaw cbbc3f19c1 Tokio Kikuchi's fix for SF bug #1629369; folding whitespace allowed in the

Barry Warsaw 1e3c3b15df decode_rfc2231(): As Christian Robottom Reis points out, it makes no sense to
test for parts > 3 when we use .split(..., 2).
2006-10-04 02:06:36 +00:00
Barry Warsaw d92ae78bdb Forward port some fixes that were in email 2.5 but for some reason didn't make
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.
2006-07-26 05:54:46 +00:00
Barry Warsaw b110bad2d9 More RFC 2231 improvements for the email 4.0 package. As Mark Sapiro rightly
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.
2006-07-21 14:51:07 +00:00
Barry Warsaw 18d2f39af7 decode_rfc2231(): Be more robust against buggy RFC 2231 encodings.
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.
2006-07-17 23:07:51 +00:00
Barry Warsaw dbcc8d9b24 Port forward from 2.4 branch:
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.

Barry Warsaw 7cf9ce2440 Fixes for SF #1076485, which I'll apply to the CVS head too. The problem was
caused by a self._input.readline() call that wasn't checking for the
NeedsMoreData marker.

msg_43.txt contains a message that illustrates the problem, when
email.message_from_*() is called.  That interface uses the Parser API, which
splits reads into 8192 byte chunks.  It so happens that for the test message,
the 8192 chunk falls inside a message/delivery-status, which is where in the
FeedParser the readline() call was that didn't check for NeedsMoreData.

I also added an assert to unreadline() so it'll be more evident if an attempt
to push back NeedsMoreData ever happens again.

Bump the email package version number.

Barry Warsaw 99b7d6445c There's likely nothing more to do to the email package before Python 2.4 is

Barry Warsaw 2e8c1f189a Fix for SF bug #1072623. When the last line of the input string does not end
in a newline, and it's an end boundary, the FeedParser wasn't recognizing it
as such.  Tweak the regexp to make the ending linesep optional.

For grins, clear self._partial when closing the BufferedSubFile.

Added a test case.

Barry Warsaw dee0cf12e3 Fix SF bug # 1030941. In _parsegen(), in the clause where we're
capturing_preamble but we found a StartBoundaryNotFoundDefect, we need to
consume all lines from the current position to the EOF, which we'll set as the
epilogue of the current message.  If we're not at EOF when we return from
here, the outer message's capturing_preamble assertion will fail.

Barry Warsaw bb11386730 Big email 3.0 API changes, with updated unit tests and documentation.
Briefly (from the NEWS file):

- Updates for the email package:
  + All deprecated APIs that in email 2.x issued warnings have been removed:
    _encoder argument to the MIMEText constructor, Message.add_payload(),
    Utils.dump_address_pair(), Utils.decode(), Utils.encode()
  + New deprecations: Generator.__call__(), Message.get_type(),
    Message.get_main_type(), Message.get_subtype(), the 'strict' argument to
    the Parser constructor.  These will be removed in email 3.1.
  + Support for Python earlier than 2.3 has been removed (see PEP 291).
  + All defect classes have been renamed to end in 'Defect'.
  + Some FeedParser fixes; also a MultipartInvariantViolationDefect will be
    added to messages that claim to be multipart but really aren't.
  + Updates to documentation.

Barry Warsaw e8bedeb45b Resolution of bug #997368, "strftime() backward compatibility".

Barry Warsaw 4e59bc1e67 readline(): RFC 2046, section 5.1.2 (and partially 5.1) both state that the
parser must recognize outer boundaries in inner parts.  So cruise through the
EOF stack backwards testing each predicate against the current line.

There's still some discussion about whether this is (always) the best thing to
do.  Anthony would rather parse these messages as if the outer boundaries were
ignored.  I think that's counter to the RFC, but might be practically more
useful.  Can you say behavior flag?  (ug).

Hye-Shik Chang 3e2a306920 Add CJK codecs support as discussed on python-dev. (SF #873597)
Several style fixes are suggested by Martin v. Loewis and
Marc-Andre Lemburg. Thanks!
2004-01-17 14:29:29 +00:00
Barry Warsaw 4a44293735 Fixes to support CJKCodecs as per SF bug #852347. Actually, this
patch removes dependencies on the old unsupported KoreanCodecs package
and the alternative JapaneseCodecs package.  Since both of those
provide aliases for their codecs, this removal just makes the generic
codec names work.

We needed to make slight changes to __init__() as well.

This will be backported to Python 2.3 when its branch freeze is over.

Barry Warsaw b03136ad52 __init__(): The docstring was incorrect regarding how header wrapping
gets done when maxheaderlen <> 0.  The header really gets wrapped via
the email.Header.Header class, which has a more sophisticated
algorithm than just splitting on semi-colons.

test program.

test_rfc2231_no_language_or_charset_in_boundary(),
test_rfc2231_no_language_or_charset_in_charset(): New tests for proper

can be None, and what to do in that situation.

Barry Warsaw 0b6f0d8810 decode_rfc2231(): We need to urllib.unquote() the value even if the
charset and language fields are not present, e.g. as in:

    title*0="This%20is%20encoded"

Barry Warsaw db6888b7df _make_boundary(): Fix for SF bug #745478, broken boundary calculation
