[Opensim-dev] Question on What is meant to happen with Offline IMs between Hypergrid Connected Grids

[Aine Caoimhe]

In my testing:

- if both users are online and in their respective homes grids an IM 
between them is *usually* but not always successful. In many cases when 
I receive an IM from someone in either Metro or in OSGrid I have to tp 
to their grid to be able to respond to it, even when they're online. 
I've also been told that people have sent me an IM when I was online but 
I never received it...this is a lot more likely to occur if I've been 
HGed elsewhere and returned to my own grid so  now any time I HG 
anywhere I always log off, wait a couple of minutes, and then log in again.

- if both users are online and both in the same grid (even if it's a 3rd 
grid) an IM will usually succeed

- if both users are online but the "target" of the IM is in a different 
grid when an IM chat is initiated, it bounces back as though the HGed 
user is offline and the message is never stored...to have an IM stored 
for someone who is offline you have to HGTP to their grid and leave them 
a message while you're there

- if both users initiate a conversation while in the same grid (or in 
their respective home grids) and keep their IM chat boxes open, they can 
often continue to communicate even when they subsequently both tp to 
other different grids. As soon as the chat is closed they cannot resume 
it and no messages are stored.

I assume the problem here is that as soon as you HGTP away from your 
home grid it treats that as a log out (it doesn't track or monitor where 
you are) so when an inbound IM comes into the grid it checks, sees 
you're offline, and responds that way. I guess once an IM "session" is 
initiated the two viewers know the target IP to send the messages to so 
as long as the session remains open they're able to continue the 
conversation no matter where they are. I would expect any undeliverable 
IM to be stored as offline IM but for whatever reason they are 
not...offline IM only works when the IM is initiated from within the 
"target" user's grid. I also don't have the faintest idea why IMs 
between myself and OSG/Metro users frequently seems to be so problematic 
even when both of us are online in our home grids whereas I don't 
encounter that problem with the majority of interactions with users in 
other grids.
