[OpenSER-Devel] urgent mi_datagram problem

[Juha Heinanen]

i'm testing the new mi_datagram interface and have run into trouble,
because openser/sems unix socket interface has stopped working.  in
order to get back to life, i'm trying to modify sems to send the mi
requests according to new openser syntax.

when openser receives from sems r_reply command:

Jul  1 20:08:28 localhost /usr/sbin/sems_openser[28119]: DBG: mi_datagram: mi_datagram_server: process 28119 has received :t_reply: 200 OK 6:733512644 5E172DC5-4687DF81000BCA21-B7CD66D0 "" 

openser reports a missing newline error (see below) although 
according to mi_datagram/README, the last argument is not followed by
newline:

     * argument_list = (argument '\n')* argument 

looking at the code it may be that mi_datagram module doesn't handle
correctly empty quoted string "".

i'm badly stuck because sems has stopped working foe me and would like
to get this resolved soon. any comments from Andreea-Ancuta or others?
