python2.6 smtplib seems to require the server to support starttls

[whycrying]

env:
Arch Linux
python2.6
when post_commit, it raises:

..............
  File "/usr/lib/python2.6/site-packages/bzrlib/plugins/email/smtp_connection.py", line 83, in _create_connection
    self._connection.starttls()
  File "/usr/lib/python2.6/smtplib.py", line 611, in starttls
    raise SMTPException("STARTTLS extension not supported by server.")
SMTPException: STARTTLS extension not supported by server.

But it works good in python2.4 and python2.5

Can anyone else reproduce this?

Could it be that you somewhere configured it to want tls?

I can't test this atm, but I have not heard any such reports in Mailman, which is now Python 2.6 compatible and probably very rarely used with STARTTLS. It's possible of course that we just haven't heard about such bugs.

here is my ~/.bazaar/bazaar.conf

[DEFAULT]
email = <email address hidden>

smtp_server=mail.zopen.cn
post_commit_mailer=smtplib
post_commit=bzrlib.plugins.email.post_commit
<email address hidden>
<email address hidden>

--------------------------------------------------------
It's that something wrong?

And the smtp_server uses exim4. Now I don't know how to set the TLS in exim4. But it works good with python 2.4 under ubuntu 8.04 and python 2.5 under fedora 10.
Or the problem of Arch Linux?

And I submited a PKGBUILD to AUR, that is:
http://aur.archlinux.org/packages.php?ID=24231

Ah,I find out something doubtful. The python-paramiko package now in archlinux is out of date. It was packaged to work with python 2.5 ! (I flagged it out of date just now.)
That maybe the problem.
I will try to install them all with easy_install.

[Martin Pool (mbp)]

This is similar to bug 340264. It may be that python2.6 changed this method to raise an exception rather than giving a warning.

[Martin Pool (mbp)]

We should catch that exception for python 2.6.

[whycrying (sour2001)]

It's also the problem.

Waiting for you to fix it!

[Martin Pool (mbp)]

It just needs a code review of https://code.edge.launchpad.net/~mbp/bzr-email/335332-starttls/+merge/4331

[Martin Pool (mbp)]

This is now fixed in bzr-email trunk, pull from there and it should be fine.

[whycrying (sour2001)]

Thank you!
I will try it later.

[whycrying (sour2001)]

It's OK now! Thx.
