[issue2849] Remove usage of rfc822 from the stdlib

New submission from Brett Cannon <brett[at]python.org>:

The rfc822 module has been deprecated for a while but is still used in the
stdlib (at least in 'cgi' and 'test_urllib2'). All uses need to go before
the module can be removed.

[issue2849] Remove usage of rfc822 from the stdlib [In reply to]

Humberto Diogenes <humberto[at]digi.com.br> added the comment:

A quick search for rfc822 imports in py3k reveals this:

$ find . -name '*.py' | xargs egrep -nr '(from|import) rfc822'
./Demo/scripts/mboxconvert.py:7:import rfc822
./Lib/cgi.py:39:import rfc822
./Lib/mimetools.py:5:import rfc822
./Lib/test/test_rfc822.py:1:import rfc822
./Lib/test/test_urllib2.py:587: import rfc822, socket
./Tools/faqwiz/faqwiz.py:210: import rfc822
./Tools/scripts/mailerdaemon.py:3:import rfc822
./Tools/versioncheck/pyversioncheck.py:2:import rfc822

The real "release blockers" should be cgi, mimetools and test_urllib2.

Humberto Diogenes <humberto[at]digi.com.br> added the comment:

Tried to just replace rfc822.Message with email.message_from_file in
cgi.py but it didn't work. I still have to figure out how to fix
FieldStorage.read_multi.

Added file: http://bugs.python.org/file10376/remove_rfc822-cgi-incomplete.py

Humberto Diogenes <humberto[at]digi.com.br> added the comment:

Seems that removing rfc822 from `cgi` is not an easy task -- please see issue 1112856.

[issue2849] Remove usage of rfc822 from the stdlib [In reply to]

Humberto Diogenes <humberto[at]digi.com.br> added the comment:

Added a patch that successfully removes rfc822 dependency from the cgi
module, using ideas from issue 1112856. I had to change one test, as the
email FeedParser ignores trailing spaces in subparts.

[issue2849] Remove usage of rfc822 from the stdlib [In reply to]

Humberto Diogenes <humberto[at]digi.com.br> added the comment:

With the attached patches, rfc822 won't be used anywhere inside Lib/
anymore (with the exception of mimetools, which is going away too).

Is there any reason to convert the files below? Shouldn't they be removed
from 3.0?
Demo/scripts/mboxconvert.py -> superseded by mailbox.py
Tools/faqwiz/faqwiz.py -> really old (1998)
Tools/scripts/mailerdaemon.py -> still useful?
Tools/versioncheck/pyversioncheck.py -> really old (1997)

Probably. I bet both the Demo and Tools directory need a thorough clean-up.

Barry A. Warsaw <barry[at]python.org> added the comment:

Reviewed and applied to Python 3.0 in r64161. The patch did not apply
cleanly for 2.6. I'm going to bump this down to critical for the first
betas. Humberto, can you back port it to Python 2.6?

So, does it make sense to backport this too?
