Dear Mailman developers,

I dare to post this problem to mailman-developers, because it is critical to us to solve it. I assume that "code insiders" as you can possibly help in this case.

While updating MM from 2.1.2 to 2.1.5 (Mailman stopped, MTA stopped, lock directory cleared manually, Apache stopped, 'check_perms -f' done) the process of updating gets stuck at a specific point. I added a 'print mlist' in 'def update_pending()' after 'for listname in Utils.list_names(): mlist = MailList.MailList(listname)'

to know where it happens:

# bin/update Upgrading from version 0x20102f0 to 0x20105f0 getting rid of old source files Updating mailing list: XXX

[...updates all lists with one "could not acquire lock" message...]

Updating Usenet watermarks

• nothing to update here Updating Mailman 2.1.4 pending.pck database WARNING: Ignoring duplicate pending ID: 7544.

  [..warns for many more "pending IDs"..]

<mailing list "list1" (locked) at 4b8300> <mailing list "list2" (locked) at 4bbdf0>

...and here the process stalls forever. I ^C-stopped the update several times, but it gets always stuck at the same list.

If I nevertheless start 2.1.5, I get around 20 of the following errors;

# mailmanctl start Starting Mailman's master qrunner. # Traceback (most recent call last): File "/usr/pack/mailman-2.1.5-inf/bin/qrunner", line 270, in ? main() File "/usr/pack/mailman-2.1.5-inf/bin/qrunner", line 230, in main qrunner.run() File "/usr/pack/mailman-2.1.5-inf/Mailman/Queue/Runner.py", line 70, in run filecnt = self._oneloop() File "/usr/pack/mailman-2.1.5-inf/Mailman/Queue/Runner.py", line 99, in _oneloop msg, msgdata = self._switchboard.dequeue(filebase) File "/usr/pack/mailman-2.1.5-inf/Mailman/Queue/Switchboard.py", line 147, in dequeue data = cPickle.load(fp) EOFError [...] #

After that, MM 2.1.5 does not deliver any mails. I can go back to 2.1.2 and mail delivery continues (even for mails posted in the meantime, i.d. when 2.1.5 was running), after having given me a about a dozen errors of the following type:

Jun 26 21:43:27 2004 (1204) lost data files for filebase: 1088195523.0786779+4c5e6189f5cc4ba967f1556ffb911c03c84d6174

If I then go back to bin/update, the process stopps within the same procedure as above, but at an other maillist (see above).

An other obervation is, that when doing bin/update, I get errors like the following with some maillists:

# bin/update [...] Updating mailing list: XXXX Updating the held requests database.

• updating old private mbox file looks like you have a really recent CVS installation... you're either one brave soul, or you already ran me
• updating old public mbox file
• This list looks like it might have <= b4 list templates around Traceback (most recent call last): File "/usr/pack/mailman-2.1.5-inf/bin/update", line 782, in ? errors = main() File "/usr/pack/mailman-2.1.5-inf/bin/update", line 672, in main errors = errors + dolist(listname) File "/usr/pack/mailman-2.1.5-inf/bin/update", line 357, in dolist os.rename(o_tmpl, n_tmpl) OSError: [Errno 2] No such file or directory

After that, bin/update exits and I have to restart it. The next run it will give the error with an other list. This happens three times, so the fourth time bin/update runs through and finally stopps at the error described at the beginning of this posting.

I'm running Python 2.2.2 on a Solaris 9 host.

Do you need more information to track down this problem?

Please reply to my personal address (fthommen@inf.ethz.ch), since I am not member of this list and please be very specific if it comes to coding, as I dont really speak Python.

Thanks a lot in advance from me and my 70 maillists :-)
