BINGO! The results listed several lists without error, and then there was
the attribute error for real_name. The preceeding list was the mailman
list! So with appropriate backups, I renamed the mailman list's
config.pck.last file to config.pck and ran mylist_lists again, and it ran
without error, listing all of my lists! And guess what, the list overview
web page works as expected now!
Traceback (most recent call last):
File "./mylist_lists", line 123, in ?
File "./mylist_lists", line 103, in main
longest = max(len(mlist.real_name), longest)
File "/var/lib/mailman/Mailman/MailList.py", line 144, in __getattr__
raise AttributeError, name
Do you agree that there was something VERY subtle about what was wrong with
it? Here's a snippet from the original config.pck:
The real_name -looks- OK to a text editor, no?
Here's how it looks now:
Running diff adds to the confusion, and it's getting difficult to explain.
If I diff the present (working) config.pck (the renamed config.pck.last
file) and config-orig.pck (the problem file), there is NO DIFFERENCE.
However, if I diff config-orig.pck (problem file) and config.pck.last.orig
(the original pck.last file), there IS a difference!! So it seems that
simply renaming the "same" (according to diff) file fixed the problem?!
Some very subtle binary difference not detectable in the text output from
Luke:/var/lib/mailman/lists/mailman# diff config.pck config-orig.pck
Luke:/var/lib/mailman/lists/mailman# diff config-orig.pck
Binary files config-orig.pck and config.pck.last.orig differ
A special THANK YOU to Mark Shapiro for his patient and detailed help on
this problem. Hopefully something in this thread has helped someone else
now or in the future! - John
