Collaboration: Seeing other users is Inconsistent

[CarolineM]

There are 3 of us logged into a collaboration server.
The web page for eJabber says we are all online.
Last week we could all see each other.

Today one person can see one other person but the other 2 of us can't see anyone.

We are willing to help debug but we are not sure where to start.

This continues to be an issue. Sometimes we see each ohter sometimes we don't, rebooting the XOs a few times seems to help.

My XO is not using automatic or extreme power management

Please follow ​http://wiki.laptop.org/go/Telepathy_debugging to enable logging on the XOs. Please provide presenceservice.log from each XO that has failed to see all the other XOs.

I'm having collaboration problems, too. I'm trying to collaborate among a real XO (updated yesterday to build 767), a desktop PC running latest LiveCD (XO-LiveCD_081201.iso), and a desktop PC running Ubuntu 8.04.1 up-to-date with latest Sugar from Ubuntu repository. Collaboration is inconsistent, doesn't detect when one computer goes offline (reboots or whatever), doesn't seem to link up invitations and joins, doesn't show a shared activity on Neighborhood view when it should, etc.

Is there a writeup of the collaboration protocols for making presence known, inviting, joining, detecting loss of one member (offline), and so on? Perhaps something like a UML sequence diagram would help so testers can run through the proper sequences and see what works and doesn't work, where things get stuck or lost, etc.

overbyte, ​http://wiki.laptop.org/go/Presence_Service may help. It should link to all the relevant documentation we have.

It sounds like you are using serverless collaboration, which unfortunately is unreliable and difficult to debug. Furthermore, we have scalability problems and bugs in the server collaboration using ejabberd, including where a server's reliability degrades with the number of users registered on it.

Please provide presenceservice.log from each machine and we'll try to debug from that. See ​http://wiki.laptop.org/go/Telepathy_debugging to enable logging on the XO, and http://sugarlabs.org/go/Community/Distributions/Ubuntu to enable logging on Ubuntu.

There have been changes to this part of the code. Are people still seeing this problem?

[gregdek]

cc:ing cassidy here. If we are still seeing these kinds of problems with the latest code drops, we'd like to knock them out for 0.84 if possible.

[gdesmott]

Are you using Gadget or the shared roster?

[morgs]

The reporters have not provided any log files, so there is nothing we can specifically work on.

Please use these instructions on non XO http://sugarlabs.org/go/BugSquad/TelepathyDebugging

Caroline says this got much better since the last updates, so we'll tentatively close this one and keep an eye open for inconsistencies.
