? This very message came to me with the following header: Errors-To: mailman-developers-admin(a)python.org All my bounces come to the list admin address, set in the admin webpage, in the second field of General Options. Do you have that set to something, and bounces still come to root? > 2.

Membership management chunking requires two authentications..
by Ted Cabeen 19 Jul '00

19 Jul '00

Mailman: 1.1 Python: 1.5.2 OS: Solaris 5.7 I don't know if this has been fixed in the CVS version, but I thought I'd submit it anyways. There seems to be a small authentication bug with the chunking in the membership management page. The page will load up correctly the first time it is accessed with the first chunk size shown. However, when you request a different chunk, it requires a reauthentication and then gives the chunk=0 page instead of the requested chunk. If you then click on the alternate chunk it loads fine. However, the additional click and authentication is annoying. -- Ted Cabeen http://www.pobox.com/~secabeen secabeen(a)pobox.com Check Website or finger for PGP Public Key secabeen(a)midway.uchicago.edu "I have taken all knowledge to be my province." -F.

Re-tries for failed SMTPDirect deliveries
by Barry A. Warsaw 01 Jun '00

01 Jun '00

Last night, I added some code to queue messages that fail delivery when using SMTPDirect. What happens is this: If a message either totally fails delivery (e.g. the smtp socket connect fails) or partial delivery fails for some, but not all, recipients, then the message is stored on the file system for a re-try later. For every failed message, two files are created. The base name of these files is the SHA hexdigest dump of the message text. This should be nearly guaranteed unique. A new directory contains these files, called `qfiles'. The first file created is the complete plain text of the failed message. The second file is a marshal of useful information related to the failed delivery. This contains the listname and the failed recip list along with a few other moderately useful bits of info. There's a new cron script called `qrunner' which cruise the files in qfiles. It claims a lock (to prevent multiple qrunner processes) and then goes through each file it finds, attempting redelivery. If there are any problems reading a qfile file, it skips it for next time (assumes it's a transient problem with the file, but logs a message). When qrunner notices that the message has been handed off the the smtp daemon for all outstanding recipients, it deletes the two message files. I've moderately tested this stuff with total delivery failure by shutting off my smtp daemon, attempting some deliveries, turning it back on and running qrunner. I don't have the time right now to test partial delivery failures, but I still claim that without DSN support, these will be unlikely. Hopefully some of you can help look at this. I'm about to check all this stuff in. Let me know what you think. -Barry

pipermail/hypermail mbox-archive
by Thomas Wouters 01 Jun '00

01 Jun '00

There was a short discussion a month or so ago about the hyperarch 'mbox' archives having the wrong kind of date in the 'From ' lines... 'unixfrom' lines should have a very specific dateformat, namely that which 'time.ctime' returns. The following patch fixes Archiver/HyperArch.py. However, I'm not entirely sure if it will work correctly in other locales... can anyone test that, and propose a locale-independant way of producing this format ?

Re: [Mailman-Developers] lock lifetime

Regarding signals: Some time back, I occasionally received reports from my users that some list, while its web admin interface was being accessed, suddenly got unresponsive for a period of time that matched the lock lifetime pretty well. There were no entries/backtraces in logs/error, but I sometimes saw list lock files left lying around, and upon checking their contents found that their creating process was now gone. I suspect this is what happened: * Web browser connects to Mailman. * Web browser for some reason closes its side of the connection before Mailman has given any response. * When Mailman tries to print out its response, it receives a SIGPIPE. I tried fixing the problem with this patch: Index: driver =================================================================== RCS file: /projects/cvsroot/mailman/scripts/driver,v retrieving revision 1.19 diff -u -r1.19 driver --- driver 2000/04/06 19:30:38 1.19 +++ driver 2000/04/12 14:43:23 @@ -89,6 +89,13 @@ main() finally: sys.stderr = sys.__stderr__ + except IOError, e: + import errno + if e.errno == errno.EPIPE: + # Log something + logger.write("EPIPE caught, ARGV=%s\n" % sys.argv) + else: + raise except SystemExit: # this is a valid way for the function to exit pass (Well, something like that patch anyway... :) However, if my understanding of the problem is right, and this is the correct fix for it, I don't understand why the bare except: clause around the run_main() call in driver didn't kick in to produce a log entry... Does anyone have any insight on how to properly avoid SIGPIPEs in python? -- Harald

Yup. This might produce a SIGPIPE, and/or the corresponding IOError EPIPE, and I've experienced that these didn't always get caught -- an attempt at a fix is near the end of run_main in <URL: http://www.uio.no/~hmeland/tmp/mailman-userdb/scripts/driver>, but I'm by no means positive that it's the Right fix. -- Harald

suggestion for heldmsg placement
by Ricardo Kustner 30 Apr '00

30 Apr '00

Hi, I think it could be better to place the heldmsg-* files that are created for messages held for approval in a directory like ~mailman/listname/lists/mailinglist/pending instead of all messages for all lists in ~mailman/data... does anybody agree with me? :) Ricardo. --

change the envelope sender with Sendmail.py?
by Brian Edmonds 30 Apr '00

30 Apr '00

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've been having a problem (using 2.0beta2) with a number of bounce messages going back to the poster rather than the list owner. I've tracked it down to the envelope sender being left as the poster, and not being changed to the list admin address. It appeared to be inconsistent since some MTAs were handling Errors-To, which was being set to the admin address, while some use the envelope sender. The change is on line 91 of Handlers/Sendmail.py[1], where msg.GetSender needs to become mlist.GetAdminEmail. Brian. [1] I don't know if this is also a problem in the direct SMTP module. I'm using Sendmail.py because my MTA is sendmail, but I'm using postfix in outgoing only configuration for the list delivery since mailman was getting sendmail to send each message as one huge batch of addresses. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.1 (GNU/Linux) Comment: Processed by Mailcrypt 3.5.5 and Gnu Privacy Guard <http://www.gnupg.org/> iD8DBQE5DKQbcCEFQUX5+OwRAvxkAJ91zqlhXTD5XAezZ/PHKKDWa+jNagCeKFO1 2zVlOt8M2I0sn3qFAXD2XGY= =79kq -----END PGP SIGNATURE-----

nightly_gzip not compressing weeklys?
by Ron Jarrell 28 Apr '00

Does nightly_gzip only handle monthlies? It's not clear from the code (and my knowledge of python :-)), but it sure looks like it's only compressing monthlys.
