It took all of my sunday, but I just finished porting Ben Gertzfield's
excellent dupe removal patch to mailman cvs
(I also had to learn some python in the process. I'm starting to believe
that Mailman is a conspiracy to get people to learn python :-p)
In a nutshell, the patch does two things:
1) it does not send you your list copy if
- your subscribed Email address is already in the headers
- you already received the message through another list (Cc accross two
lists or more on the same site)
2) The new "nodupes" setting is really something you probably want as a
default on all lists. I also had lists were people wanted notmetoo as a
default too.
Ben's fix for that is to have a bitfield per list that you can set and
that states which options newly added users get.
As Ben said, this breaks the one patch one functionality rule, but when I
ported his work to mailman-cvs, I realized that it didn't make sense to take
them apart.
However, Barry, if that would stop you from merging #1 in CVS, I could
remove it, but I'm not sure why one would want to.
I've done reasonable tests to make sure I didn't break all of mailman in the
process, and the core logic hasn't changed, so the basic functionality is
the same that Ben had written and that has been used for 6-9mo? on the
debian lists now.
In other words, it should work (it does for me, and I'm already running it
on my production mailman-cvs list server), but there is always the chance
that there might be a corner case buglet left somewhere.
Considering this was a pain to port, and how this puts to rest many of the
reply-to munging discussions (the only real argument for reply-to munging is
that it "solves" the duplicate mails you other receive when people use reply
to all), I'm hoping that this could make it in (wink, wink :-D)
Thanks,
Marc
