Cesc,
Great work! I have been working on SEMS the last few days, evaluating SEMS
for use in
ONsip.org Getting Started. So, I tried to replicate your problem,
which I successfully did. I applied your patch and it seems to be working.
:-)

Subject: Re: [Serusers] Local ACKs for SER-SEMS
Hi,
I found it ... now it works. There is a pseudo-patch at the end of the
message (pseudo because it cannot directly be applied ... it is just
to mark the three lines i needed to change ... ). The patch is for
ser-rel-0.9.4 (i send it to openser-devel ... i did not look, but
probably the problem is there too).
It is just a small bug ... from 0.9.0 to 0.9.4 a part of the loop was
moved outside the loop, to the end of the function ... and in a place
where there used to be a return now the loop would just continue ...
Then, the matching_3261 function would, if a transaction matching the
ACK was found, would always return e2e ack ... even though the
ack_matching function returned it as a local transaction ...
For me, this patch fixes it ... but as it is a delicate part, i am not
sure if it affects other parts ... i don't think so, but ...
Tks for all who took a look at the problem (greger, jan, samuel, ... )!
Regards,
Cesc
PS - This should affect anyone using SEMS ... so, if no one saw it ...
does it mean there is really a few people using it? what a pitty ...
