6 months ago I did not know someone was still interested in this project. Saying this I have been working on this project recently to revive the front end and also look at how I can make mutex locking better. I was thinking about making it useful for DWDW as PCEP is used there as well. I will try to take a look at this issue today or tomorrow as I have everything set up.

6 months ago I moved the mutex lock so that part should work now. But that also means you would probably get an error in the logs somewhere.
err := ptypes.UnmarshalAny(lsMessage, &NLRINode) if err != nil { logrus.Println(err) return } node := &Node{ ASN: NLRINode.LocalNode.Asn, IGPRouteID: NLRINode.LocalNode.IgpRouterId, } var LsAttribute api.LsAttribute for _, item := range p.Pattrs { if ptypes.Is(item, &LsAttribute) { err := ptypes.UnmarshalAny(item, &LsAttribute) if err != nil { logrus.Println(err) return } node.RouterID = LsAttribute.Node.LocalRouterId node.Name = LsAttribute.Node.Name node.SRRangeStart = int(LsAttribute.Node.SrCapabilities.Ranges[0].Begin) node.SRRangeEnd = int(LsAttribute.Node.SrCapabilities.Ranges[0].End) } }
Because UnmarshalAny does not work for some reason. Potentially due to new attributes in BGP LS. I can fix it too if you are interested and can provide some data on Juniper version etc...

Yep now it crashes with

I don't mind being guinea pig if you like - I'm actually looking at ODL at the same time.. running JunOS 21.4R3 atm.

6 months ago I added a nil pointer check so it will should not crash anymore. I also added a debug check to print out whole LsAttribute as json.

Seems to have done the trick, it's no longer crashing at least :)

5 months ago This issue is back! :( I established a bgp-ls session with a ios-xr device and when it started actually sending data the crash came back :(

After a bit of hassle I managed to get gopcep to function. Have to control it from remote so had to hackaround in your .js and stuff to get it functioning. But after finally getting everything up and running I attached it to a Juniper box and configured all knobs that has to be configured.. when it finally started to send bgp-ls updates gopcep broke down with the error "fatal error: sync: Unlock of unlocked RWMutex".
Complete log from start to crash:
