[ANNOUNCE] Mailman 2.1 alpha 2
by barry＠digicool.com March 25, 2002

March 25, 2002

This the official announcement for Mailman 2.1 alpha 2. Because it's an alpha, this announcement is only going out to the mailman-* mailing lists. I'll make two warnings: you probably should still not use this version for production systems (but TIA for any and all testing you do with it!), and I've already had a couple of bug fixes from early adopters. 2.1a2 should still be useful, but you might want to keep an eye on cvs and the mailman-checkins list for updates. I am only making the tarball available on SourceForge, so you'll need to go to http://sf.net/projects/mailman to grab it. You'll also need to upgrade to mimelib-0.4, so be sure to go to http://sf.net/projects/mimelib to grab and install that tarball first. To view the on-line documentation, see http://www.list.org/MM21/index.html or http://mailman.sf.net/MM21/index.html Below is an excerpt from the NEWS file for all the changes since 2.1alpha1. There are a bunch of new features coming down the pike, and I hope to have an alpha3 out soon. I'm also planning on doing much more stress testing of this version with real list traffic, and I'm hoping we'll start to get more languages integrated into cvs. Enjoy, -Barry -------------------- snip snip -------------------- 2.1 alpha 2 (11-Jul-2001) - Building o mimelib 0.4 is now required. Get it from http://mimelib.sf.net. If you've installed an earlier version of mimelib, you must upgrade. o /usr/local/mailman is now the default installation directory. Use configure's --prefix switch to change it back to the default (/home/mailman) or any other installation directory of your choice. - Security o Better definition of authentication domains. The following roles have been defined: user, list-admin, list-moderator, creator, site-admin. o There is now a separate role of "list moderator", which has access to the pending requests (admindb) page, but not the list configuration pages. o Subscription confirmations can now be performed via email or via URL. When a subscription is received, a unique (sha) confirm URL is generated in the confirmation message. Simply visiting this URL completes the subscription process. o In a similar manner, removal requests (via web or email command) no longer require the password. If the correct password is given, the removal is performed immediately. If no password is given, then a confirmation message is generated. - Internationalization o More I18N patches. The basic infrastructure should now be working correctly. Spanish templates and catalogs are included, and English, French, Hungarian, and Big5 templates are included. o Cascading specializations and internationalization of templates. Templates are now search for in the following order: list-specific location, domain-specific location, site-wide location, global defaults. Each search location is further qualified by the language being displayed. This means that you only need to change the templates that are different from the global defaults. Templates renamed: admlogin.txt => admlogin.html Templates added: private.html - Web UI o Redesigned the user options page. It now sits behind an authentication so user options cannot be viewed without the proper password. The other advantage is that the user's password need not be entered on the options page to unsubscribe or change option values. The login screen also provides for password mail-back, and unsubscription w/ confirmation. Other new features accessible from the user options page include: ability to change email address (with confirmation) both per-list and globally for all list on virtual domain; global membership password changing; global mail delivery disable/enable; ability to suppress password reminders both per-list and globally; logout button. [Note: the handle_opts cgi has gone away] o Color schemes for non-template based web pages can be defined via mm_cfg. o Redesign of the membership management page. The page is now split into three subcategories (Membership List, Mass Subscription, and Mass Removal). The Membership List subcategory now supports searching for member addresses by regular expression, and if necessary, it groups member addresses first alphabetically, and then by chunks. Mass Subscription and Mass Removal now support file upload, with one address per line. o Hyperlinks from the logos in the footers have been removed. The sponsors got too much "unsubscribe me!" spam from desperate user of Mailman at other sites. o New buttons on the digest admin page to send a digest immediately (if it's non-empty), to start a new digest volume with the next digest, and to select the interval with which to automatically start a new digest volume (yearly, monthly, quarterly, weekly, daily). DEFAULT_DIGEST_VOLUME_FREQUENCY is a new configuration variable, initially set to give a new digest volume monthly. o Through-the-web list creation and removal, using a separate site-wide authentication role called the "list creator and destroyer" or simply "list creator". If the configuration variable OWNERS_CAN_DELETE_THEIR_OWN_LISTS is set to 1 (by default, it's 0), then list admins can delete their own lists. This feature requires an adaptor for the particular MTA you're using. An adaptor for Postfix is included, as is a dumb adaptor that just emails mailman@yoursite with the necessary Sendmail style /etc/alias file changes. Some MTAs like Exim can be configured to automatically recognize new lists. The adaptor is selected via the MTA option in mm_cfg.py - Email UI o In email commands, "join" is a synonym for "subscribe". "remove" and "leave" are synonyms for "unsubscribe". New robot addresses are support to make subscribing and unsubscribing much easier: mylist-join@mysite mylist-leave@mysite o Confirmation messages have a shortened Subject: header, containing just the word "confirm" and the confirmation cookie. This should help for MUAs that like to wrap long Subject: lines, messing up confirmation. o Mailman now recognizes an Urgent: header, which, if it contains the list moderator or list administrator password, forces the message to be delivered immediately to all members (i.e. both regular and digest members). The message is also placed in the digest. If the password is incorrect, the message will be bounced back to the sender. - Performance o Refinements to the new qrunner subsystem which preserves FIFO order of messages. o The qrunner is no longer started from cron. It is started by a Un*x init-style script called bin/mailmanctl (see below). cron/qrunner has been removed. - Command line scripts o bin/mailmanctl script added, which is used to start, stop, and restart the qrunner daemon. o bin/qrunner script added which allows a single sub-qrunner to run once through its processing loop. o bin/change_pw script added (eases mass changing of list passwords). o bin/update grows a -f switch to force an update. o bin/newlang renamed to bin/addlang; bin/rmlang removed. o bin/mmsitepass has grown a -c option to set the list creator's password. The site-wide `create' web page is linked to from the admin overview page. o bin/newlist's -o option is removed. This script also grows a way of spelling the creation of a list in a specific virtual domain. o The `auto' script has been removed. o bin/dumpdb has grown -m/--marshal and -p/--pickle options. o bin/list_admins can be used to print the owners of a mailing list. o bin/genaliases regenerates from scratch the aliases and aliases.db file for the Postfix MTA. - Archiver o New archiver date clobbering option, which allows dates to only be clobber if they are outrageously out-of-date (default setting is 15 days on either side of received timestamp). New configuration variables: ARCHIVER_CLOBBER_DATE_POLICY ARCHIVER_ALLOWABLE_SANE_DATE_SKEW The archived copy of messages grows an X-List-Received-Date: header indicating the time the message was received by Mailman. o PRIVATE_ARCHIVE_URL configuration variable is removed (this can be calculated on the fly, and removing it actually makes site configuration easier). - Miscellaneous o Several new README's have been added. o Most syslog entries for the qrunner have been redirected to logs/error. o On SIGHUP, qrunner will re-open all its log files and restart all child processes. See "bin/mailmanctl restart". - Patches and bug fixes o SF patches and bug fixes applied: 420396, 424389, 227694, 426002, 401372 (partial), 401452. o Fixes in 2.0.5 ported forward: Fix a lock stagnation problem that can result when the user hits the `stop' button on their browser during a write operation that can take a long time (e.g. hitting the membership management admin page). o Fixes in 2.0.4 ported forward: Python 2.1 compatibility release. There were a few questionable constructs and uses of deprecated modules that caused annoying warnings when used with Python 2.1. This release quiets those warnings. o Fixes in 2.0.3 ported forward: Bug fix release. There was a small typo in 2.0.2 in ListAdmin.py for approving an already subscribed member (thanks Thomas!). Also, an update to the OpenWall security workaround (contrib/securelinux_fix.py) was included. Thanks to Marc Merlin.

Re: [Mailman-Users] Upgrading from 2.0b5 to 2.1a2
by barry＠zope.com Nov. 6, 2001

Nov. 6, 2001

[Note: I'm moving this discussion to malman-developers. -baw] >>>>> "JAA" == Jose A Accino <jaccino(a)ieev.uma.es> writes: JAA> Is there any clean way to make a smooth upgrade from 2.0b5 to JAA> lates 2.1a2?

JAA> However, I've been unable to upgrade the old lists. Here are JAA> the main points: There's two ways to upgrade, neither of which has gotten a lot of testing. Based on you're message I tried the first way, and I'm about to check in a bunch of patches to make that go smoother. I'll try the second way soon. 1) Install a fresh virgin MM2.1 in /usr/local/mailman and then move lists from /home/mailman (MM2.0.x) to /usr/local/mailman. This way lets you migrate lists one at a time, gaining confidence in the new system in measured increments. I will probably upgrade {python,zope}.org this way. 2) Install MM2.1 overtop an existing MM2.0.x installation and have everything just magically work. I'll probably upgrade wooz.org's production lists this way. Both ought to work, and ought to be easy. After the checkins, here's a recipe that makes #1 easy: - Do a fresh install of MM2.1 in /usr/local/mailman according to the instructions. - Copy or move `mylist' by first moving /home/mailman/lists/mylist to /usr/local/mailman/lists/mylist and /home/mailman/archives/private/mylist.mbox to /usr/local/mailman/archives/private BTW, I used rsync for this, just cause it's a cool tool and I can actually remember how to invoke it with the right options. :) That's it. Everything else should just work, except for possibly two minor complications. - If your web server is going to support both installations, it's possible you'll have two different base urls, one for your MM2.0.x installation and one for your MM2.1 installation. If so, you'll need to manually change each moved list's web_page_url attribute. Fortunately, I'm about to add a script called `fix_url' which will reset a list's web_page_url to mm_cfg.DEFAULT_URL. So if you configure mm_cfg.py correctly, then run fix_url, you should be golden. I.e. % bin/withlist -l -r fix_url mylist - Same dealie with your MTA, i.e. your wrapper aliases may point to two different directories. Here, because I use Postfix and glued them together as described in README.POSTFIX, all I needed to do was run bin/genaliases and the new list aliases got installed. I'm sure that if you use Exim and glued them together as per README.EXIM, you probably don't need to do anything. (I'm still waiting on contributions for better gluing instructions for Sendmail, qmail, and any others.) -Barry

Bug in mail->news gateway in 2.0.5 (and *simple* fix)
by "Jürgen A. Erhard" Oct. 20, 2001

Oct. 20, 2001

Bug: in Mailman/Handlers/ToUsenet.py, there are spaces inserted after colons where they are missing ("NNTP is strict about spaces after the colon in headers"). If a colon appears in a continuation line, it is treated as a header colon. Fix: skip lines that start with whitespace. For those interested, the history of the finding of the bug: Problem: my signed emails appeared on Usenet garbled. The multipart boundary had an extra space inserted (which of course the actual boundaries hadn't). After some exchange with Martin Armstrong (who made me aware of this) we concluded it had to be the mail->news gateway (as my direct mail to him, also signed, wasn't garbled). I then investigated ToUsenet.py, and found the error. Why this hasn't hit a lot more often is simple: most MUA seem to use some random gibberish as the boundary string. SEMI doesn't... Of course, if this is fixed in 2.1, you can ignore this (assuming that it comes out soonish ;-) Bye, J -- Jürgen A.

MM 2.1a2: bug if dont_respond_to_post_requests=N -> lang is undefined
by Luca Maranzano Sept. 10, 2001

Sept. 10, 2001

Hi, I've already submitted a bug to SF about this, but I can confirm that if I set dont_respond_to_post_requests to NO then this seems to arise a bug in Hold.py, i.e. the variable lang is not set and I get the following error: Aug 30 16:43:04 2001 (17624) Uncaught runner exception: Local variable 'lang' referenced before assignment Aug 30 16:43:04 2001 (17624) Traceback (most recent call last): File "/home/mailman/Mailman/Queue/IncomingRunner.py", line 134, in _dopipeline sys.modules[modname].process(mlist, msg, msgdata) File "/home/mailman/Mailman/Handlers/Hold.py", line 145, in process hold_for_approval(mlist, msg, msgdata, ModeratedPost) File "/home/mailman/Mailman/Handlers/Hold.py", line 277, in hold_for_approval charset=Utils.GetCharSet(lang)) UnboundLocalError: Local variable 'lang' referenced before assignment I think that the patch is quite simple, but I'm not yet able to provide it :) MM 2.1a2.

[PATCH] Duplicate mail avoiding in Mailman
by Ben Gertzfield Sept. 2, 2001

Sept. 2, 2001

Finally! Here's the patch to avoid sending out list duplicates to users who don't want it. This is a solution to the never-ending feuding on various Debian mailing lists about whether or not people should Cc: folks already on the list; hopefully, this user-configurable behavior will make everyone's lives easier. This patch is against mailman CVS. The patch adds a DontReceiveDuplicates flag to mm_cfg (value 128). By default, this is 0, which is the same as our current behavior. If DontReceiveDuplicates is set to 1 for the user, then they will not receive a list message if: 1) the qrunner process has already set a mail with that message-id to that user -or- 2) the user is specifically listed in the To:, Cc:, Resent-To:, or Resent-Cc: fields. If DontReceiveDuplicates is set to 0 and Personalization is enabled for the list, a X-Mailman-Duplicate: yes will be added to every duplicate message sent out (not the first) to allow users to filter for themselves. I have not done any i18n for this code, mea culpa. But the option is settable via the web interface or the mail interface. (it's the "nodupes" option via mail.) Issues: 1) What happens if people fake their Message-IDs? It's possible (but hard) to stop real list mail from coming through to someone who doesn't get duplicates, if you send out lots of messages with the same Message-ID. 2) Does this use a lot of memory? I'm using a two-level hash to store the message IDs and email addresses that have been seen; I don't know if this will grow huge on big sites. 3) Is there any way to add the X-Mailman-Duplicate: yes header to various users when the admin is not using Personalization on the lists? 4) If multiple qrunner processes end up handling mails, it's possible a user who doesn't want duplicates will get them. How can we fix this? 5) Some users probably don't want list duplicates if the message is addressed to multiple lists that they belong to, but DO want duplicates if they're specifically listed in To:/Cc:/etc. Should we make yet another option for this? Please, comments are definitely appreciated. The patch works for me, as long as the previous patch I sent to the list (allowing users to actually set options) is applied.

Easy question about 2.1a2 - I hope.
by Wayne Ringling Aug. 31, 2001

Aug. 31, 2001

I was able to get Mailman 2.1a2 working on my SuSe 7.2 box. I have done some testing and all seems to be working fine. Nice job Barry! I have been customizing the listinfo pages and can't seem to find where I can change the text displayed with <MM-Editing-Options>. Is there any way to change this info? or is it hard coded into a module. If so then which module, I think I could hack it from there. Also, one other thing, in the README docs that talks about customizing the install, a blurb about how to edit the user interface pages might be a needed addition. I went back into the list archives to learn how to make custom list specific pages. But some users won't go to that extent. TIA Wayne Ringling

Why no regex for forbidden_posters[] ?
by Nathan V. Patwardhan Aug. 30, 2001

Aug. 30, 2001

All, I'd hoped that Mailman would let me have "closed" lists in the sense that I could reject anything from outside of 'atg.com'. forbidden_posters[], I figured, was implemented to take a regular expression. Instead, it seems that Utils.py implements FindMatchingAddresses(...), which returns an *exact match* of an address. This isn't the behavior that I'd hoped for, since (a) we're sure to have open lists that are only used internally and (b) So, I guess that I have two questions: 1. What would be wrong with having something like this: # in a list's config forbidden_posters = ['^.*(a)(?!atg.com$)', 'another_regex_here', 'etc...'] # from Handlers/Hold.py addrs = Utils.FindMatchingAddresses(sender, forbiddens) if addrs: hold_for_approval(mlist, msg, msgdata, ForbiddenPoster) ... def FindMatchingAddresses(sender, forbiddens): res = [] for each_banned in forbiddens: p = re.compile(each_banned) m = p.match(each_banned) if m != None: res.append(each_banned) return res 2. Instead of hold_for_approval(...), would anyone have any objections if a method like kill_forbidden_message(...) was implemented? We have many, many lists and often times a list administrator (the users themselves) won't think to delete messages that are blocked, yet get held for approval. -- Nate Patwardhan Art Technology Group ******************************************** $ ping elvis elvis is alive

I'm standing back! ;-) But this is where Texinfo improves on the troff -man markup; it generally relies less on convention and template-driven authoring to get the job done, so is easier to convert. > I really like how the Python documentation is done.

I agree. DocBook would solve both the general documentation and man page problem. So go with DocBook like I told you. ;-) Seriously, the common tools for DocBook leave something to be desired, especially for typeset formats. Writting a better tool would not be terribly hard these days, especially if you went with the XML version of DocBook. -Fred -- Fred L. Drake, Jr. <fdrake at acm.org> PythonLabs at Zope Corporation
