[Systers-dev] Proposal to split dlist handler

[Erica Wolfe]

Hello all,

I would like some feedback on a fix I propose.

While researching a pair of unsubscription bugs, 386133 and 3244206, I was
only able to reproduce 324406.  However, I was able to determine that the
problems stem from running dlist unsubscribe emails through all the Mailman
handlers.  Expanding on the patch proposed by beachbrake, splitting the
dlist handler into two parts resolves the issues so I created an early dlist
handler and a late dlist handler.  The early dlist handler contains only the
code to unsubscribe from dlists but I chose a generic name as I expect that
other folks may wont to put code in the file at some point as well.  The
late dlist handler contains everything except the unsubscribe
functionality.  In addition, I created a dlist handler util file but can put
that code into Mailman/DlistUtils if that is deemed more appropriate.

Does this seem logical and reasonable to folks?

Regards,
