=========
Archivers
=========
Mailman supports pluggable archivers, and it comes with several default
archivers.
>>> mlist = create_list('test@example.com')
>>> msg = message_from_string("""\
... From: aperson@example.org
... To: test@example.com
... Subject: An archived message
... Message-ID: <12345>
...
... Here is an archived message.
... """)
Archivers support an interface which provides the RFC 2369 List-Archive
header, and one that provides a 'permalink' to the specific message object in
the archive. This latter is appropriate for the message footer or for the RFC
5064 Archived-At header.
Pipermail does not support a permalink, so that interface returns None.
Mailman defines a draft spec for how list servers and archivers can
interoperate.
>>> archivers = {}
>>> from operator import attrgetter
>>> for archiver in sorted(config.archivers, key=attrgetter('name')):
... print archiver.name
... print ' ', archiver.list_url(mlist)
... print ' ', archiver.permalink(mlist, msg)
... archivers[archiver.name] = archiver

Sending the message to the archiver
===================================
The archiver is also able to archive the message.
>>> archivers['pipermail'].archive_message(mlist, msg)
>>> import os
>>> from mailman.interfaces.archiver import IPipermailMailingList
>>> pckpath = os.path.join(
... IPipermailMailingList(mlist).archive_dir(),
... 'pipermail.pck')
>>> os.path.exists(pckpath)
True
Note however that the prototype archiver can't archive messages.
>>> archivers['prototype'].archive_message(mlist, msg)
Traceback (most recent call last):
...
NotImplementedError
The Mail-Archive.com
====================
The Mail-Archive <http://www.mail-archive.com> is a public archiver that can
be used to archive message for free. Mailman comes with a plugin for this
archiver; by enabling it messages to public lists will get sent there
automatically.
>>> archiver = archivers['mail-archive']
>>> print archiver.list_url(mlist)
http://go.mail-archive.dev/test%40example.com
>>> print archiver.permalink(mlist, msg)
http://go.mail-archive.dev/ZaXPPxRMM9_hFZL4vTRlQlBx8pc=
To archive the message, the archiver actually mails the message to a special
address at the Mail-Archive. The message gets no header or footer decoration.
>>> archiver.archive_message(mlist, msg)
>>> from mailman.queue.outgoing import OutgoingRunner
>>> from mailman.testing.helpers import make_testable_runner
>>> outgoing = make_testable_runner(OutgoingRunner, 'out')
>>> outgoing.run()
>>> from operator import itemgetter
>>> messages = list(smtpd.messages)
>>> len(messages)
1
>>> print messages[0].as_string()
From: aperson@example.org
To: test@example.com
Subject: An archived message
Message-ID: <12345>
X-Message-ID-Hash: ZaXPPxRMM9_hFZL4vTRlQlBx8pc=
Sender: test-bounces@example.com
Errors-To: test-bounces@example.com
X-Peer: 127.0.0.1:...
X-MailFrom: test-bounces@example.com
X-RcptTo: archive@mail-archive.dev
<BLANKLINE>
Here is an archived message.
>>> smtpd.clear()
However, if the mailing list is not public, the message will never be archived
at this service.
>>> mlist.archive_private = True
>>> print archiver.list_url(mlist)
None
>>> print archiver.permalink(mlist, msg)
None
>>> archiver.archive_message(mlist, msg)
>>> list(smtpd.messages)
[]
Additionally, this archiver can handle malformed Message-IDs.
>>> mlist.archive_private = False
>>> del msg['message-id']
>>> msg['Message-ID'] = '12345>'
>>> print archiver.permalink(mlist, msg)
http://go.mail-archive.dev/bXvG32YzcDEIVDaDLaUSVQekfo8=
>>> del msg['message-id']
>>> msg['Message-ID'] = '<12345'
>>> print archiver.permalink(mlist, msg)
http://go.mail-archive.dev/9rockPrT1Mm-jOsLWS6_hseR_OY=
>>> del msg['message-id']
>>> msg['Message-ID'] = '12345'
>>> print archiver.permalink(mlist, msg)
http://go.mail-archive.dev/ZaXPPxRMM9_hFZL4vTRlQlBx8pc=
>>> del msg['message-id']
>>> msg['Message-ID'] = ' 12345 '
>>> print archiver.permalink(mlist, msg)
http://go.mail-archive.dev/ZaXPPxRMM9_hFZL4vTRlQlBx8pc=
MHonArc
=======
The MHonArc archiver <http://www.mhonarc.org> is also available.
>>> archiver = archivers['mhonarc']
>>> print archiver.name
mhonarc
Messages sent to a local MHonArc instance are added to its archive via a
subprocess call.
>>> archiver.archive_message(mlist, msg)
>>> archive_log = open(os.path.join(config.LOG_DIR, 'archiver'))
>>> try:
... contents = archive_log.read()
... finally:
... archive_log.close()
>>> print 'LOG:', contents
LOG: ... /usr/bin/mhonarc -add
-dbfile /.../private/test@example.com.mbox/mhonarc.db
-outdir /.../mhonarc/test@example.com
-stderr /.../logs/mhonarc
-stdout /.../logs/mhonarc
-spammode -umask 022
